Fortune In Troilus And Cressida Essay, Research Paper Woman Fortune: Friend or Foe? The substance of Fortune in Chaucer # 8217 ; s Troilus and Criseyde. Woman Fortune and her wheel are two of the most withstanding images in world # 8217 ; s history. Witness the famous game show, Wheel of Fortune. While it might look senseless, it demonstrates that something of this build has remained with in our brain, even today. The request of karma is foremost is Chaucer # 8217 ; s Troilus and Criseyde. Chaucer gives the peruser characters with entirely clashing musings of Lady Fortune and her effect on their lives. By breaking down Boethius # 8217 ; s Consolation of Philosophy, the peruser can trust to happen an answer for these varying situations on karma. To begin with, Boethius # 8217 ; s impact on Chaucer and the character of Fortune that he presents must be inspected. When this is built up as a benchmark, the peruser can to the full comprehend the misguided judgments Troilus has sing fates. Troilus sticks, as Boethius does in his Consolation of Philosophy, to the memory of his dedicated help to Fortune. At long last, the character of Pandarus must be tended to. He, of all Chaucer # 8217 ; s characters, has an immovable catch on the universe of the Lady Fortune and her ever-evolving nature. Indeed, an investigation of the content of Troilus and Criseyde will demo that Chaucer gives Pandarus an extremely comparative capacity to that of Lady Philosophy in The Consolation of Philosophy. Boethius # 8217 ; s Consolation of Philosophy Boethius # 8217 ; s work exchanges with the cosmopolitan experience of misery. He ends up detained and under threat of executing. As Boethius explains his distresses and shortcoming # 8220 ; flighty Fortune # 8221 ; ( p. 35 ) , he ends up helped by as a matter of fact Lady Philosophy. Their treatment is introduced finally for the peruser to experience judgment on. The development curiously confronting Boethius # 8217 ; s misguided judgments of Fortune and is of inclusion to this announcement is found predominantly in Book II. Woman Philosophy brings up to Boethius definitely what the foundation of his activity is toward the start of this development. # 8220 ; You are passing over in hurting and craving for your previous good karma, # 8221 ; she lets him know ( p.54 ) . This is on the grounds that he has overlooked the genuine idea of Fortune. When he goes to a dread of Fortune and how she functions as an instrument of God, he will be mended of his disease of despondency. Boethius so moves the discussion to a face to stand up to treatment with Fortune. B.L. Jefferson, in his book Chaucer and the Consolation of Philosophy of Boethius, asserts that # 8220 ; Boethius was the first to picture Fortune in this most close to home way # 8221 ; ( p. 49 ) . Boethius # 8217 ; s treatment about karma makes three unique focuses. To begin with, that modification is the truly idea of Fortune. This alterability is called attention to by Lady Philosophy, # 8220 ; Change is her ordinary conduct, her actual nature # 8230 ; You have found the adjusting appearances of the irregular goddess, # 8221 ; she tells Boethius ( Consolation, p. 55 ) . No grown-up male can stop her wheel from turning ; it conflicts with Fortune # 8217 ; s truly nature to make so. She can kill her face from a grown-up male each piece quickly as she goes it to him. Jefferson describes the announcement thusly, # 8220 ; Absolutely without comprehension, [ Fortune ] thinks about one grown-up male than a nother # 8221 ; ( 50 ) . Following comes the resistance of Fortune without anyone else. Her announcement is straightforward: I have simply reclaimed what was mine in the primary topographic point. # 8220 ; Inconstancy is my very piece, # 8221 ; she says, # 8220 ; it is the game I neer stop to play as I turn my wheel in its ever modifying circle, loaded up with euphoria as I carry the top to the underside and the underside to the top. Indeed, lift up on my wheel in the event that you like, however wear # 8217 ; t number it a hurt when by a similar thing you start to fall, as the guidelines of the game will require # 8221 ; ( Consolation, p. 57 ) . Boethius has no confirmations for his diseases since all that he has of the sum total of what time had was given to him by Fortune. On the off chance that she chooses to take it back, it is her privilege. This ought to non direct him to the holes of distress. # 8220 ; Indeed, my truly changeability gives you just improve things, # 8221 ; Fortune tells Boethius ( 58 ) . Only as the wheel has borne him down, so would it be able to manage him back up to better things. Last, Lady Philosophy teaches Boethius in Fortune # 8217 ; s more profound essentialness, as a retainer of God. Jefferson again, # 8220 ; Of an association with Providence, Fortune herself does non appear to be perceptive, for she works indiscriminately and wantonly. However, behind her and managing her, is the all-wise Capital of rhode island. Through the hardships of Fortune, Providence makes in work powers what we presently call character # 8230 ; . In Fortune [ Boethius ] saw the instrument of God # 8221 ; ( 50 ) . This made what Boethius was making an extremely genuine issue. It was all extremely ideal to talk about the fancies of karma, however to tie it sensibly and directly to the Providence of God was a completely extraordinary issue. Boethius # 8217 ; s Influence on Chaucer It is from these purposes of proclamation with Fortune that we can perceive how Boethius affected Chaucer, especially in Troilus and Criseyde. A large portion of the writing on Troilus appears to back up this case each piece great. # 8220 ; The Boethian subject of Fortune rules Troilus and Criseyde, and Chaucer even consolidates direct receptions from the Consolation of Philosophy, # 8221 ; says Martin Camargo ( 214 ) . Jefferson says that the Consolation had more effect on Troilus than on some other long section type of Chaucer # 8217 ; s ( 120 ) . It appears, by the by, that Chaucer did non just use Boethius unpredictably in this content. He actually cautiously spread with a similar cardinal issues of Fortune and God # 8217 ; s Providence that Boethius did in his Consolation. That is the reason Pandarus sounds just like Lady Philosophy when he addresses Troilus in Book 1: # 8220 ; Than blaestow Fortune For thow craftsmanship wroth ; ye now at erst I see. Woost thow nat wel that Fortune is comune To everi manere wight in som grade? But then thow hast this solace, lo, parde, That, as recruit joies moten overgon, So bit hir sorwes passen everecho. For if enlist whiel stynte any thyng to torne, Than cessed she Fortune anon to be. Presently, sith recruit whiel by no may sojourne, What woostow if enlist mutabilite Directly as thyselven list wol Don by the, Or on the other hand that she be nothing fer fro thyn helpynge? Paraunter thow hast cause for to synge # 8221 ; ( I.841-54 ) . Similar purposes of articulation are repeated here in Chaucer # 8217 ; s ain words. Pandarus is expressing precisely the same things as Lady Philosophy # 8217 ; s proclamation. Fortune is the equivalent to each grown-up male. The delights she brings may experience away, yet so will the distresses. Her wheel can non end. She would cease to be fortune. The peruser can see the immediate correlativity between Boethius # 8217 ; s work and Pandarus # 8217 ; s words. Fortune in Troilus and Criseyde Chaucer gives Pandarus an away from of Lady Fortune. It is his character who drives Troilus and educates him, as Lady Fortune did Boethius. Camargo demands that it was of import for Chaucer that his perusers see the correlativity between the hole of the Consolation and the hole of Troilus and Criseyde. # 8220 ; Because it was of import to Chaucer that his perusers perceive the analogies among Troilus and Boethius and Pandarus and Philosophy from the earliest starting point, he took specific strivings in Book I to recall the Consolation # 8217 ; s striking opening scene # 8221 ; ( Camargo, p. 215 ) . Only as Lady Philosophy discovered Boethius under the influence of the Muses, so Chaucer starts this scene with Troilus singing altogether in his room. He other than comes to him and scolds him for his disarray roughly Fortune as noted in the progress from Book I refered to above. Be that as it may, Pandarus is truly a self-searcher with regards to Fortune. He advises Troilus and Criseyde to take the risk introduced to them b Y this affection. â€Å"By transforming Lady Philosophy’s exercise into a hidden carpe diem, Pandarus exhibits his excited belief of the transient endowments of Fortune, † Joseph Salemi composes. Pandarus energizes Troilus by expressing that Fortune must be blessing him, and Tells Criseyde this is a â€Å"good aventure† ( II.288 ) . In Book IV, Pandarus again advocates Troilus on Fortune. Notwithstanding, presently Fortune has killed her face from Troilus. He says: # 8220 ; Who woulde have wende that in so litel a throwe Fortune oure joie wold Han overthrowe? For in this universe ther is no creature, With respect to my dom, that ever saugh ruyne Straunger than this, intensive Ca or aventure. Be that as it may, who may al eschue, or al devyne? Swich is this universe! Forthi I consequently diffyne: Ne trust no wight to fynden in Fortune Ay propertee ; connect with yiftes ben comune # 8221 ; ( IV.384-92 ) . He gets a handle on that the truly idea of Fortune is to take what she has given. No 1 can comprehend her unpredictable nature, but to cognize that she changes. Pandarus proceeds to state Troilus that he should look for another affection. Most likely Fortune will bless him in the signifier of another dulcinea! This is really a Boethian tenet. As Fortune turns her wheel, at last the wheel will pass on thriving again ( Consolation, II. Pr 1 ) . Troilus has an entirely extraordinary position sing Fortune. He is substantially more like Boethius. # 8220 ; He [ Troilus ] and Pandarus speak to two each piece twisted places of Fortune: that of the self-searcher and the determinist, # 8221 ; says Joseph Salemi ( 219 ) . Jefferson other than concurs that Troilus is # 8220 ; the kind of

Running away with the field

Running away with the field (Ive come out of blogger hibernation to post something too awesome not to share, and hope you all dont mind. Welcome to the new bloggers and have a great first semester, Class of 2011!) As I wrote in a previous entry about Spring 07 classes, I took a short story writing class with Professor Junot Diaz. I was inspired to take it by Nadja 07 and Yang 09, each of whom had taken a class from him and recommended it. Good call, guys. We students in the class knew he wrote a well-known book in 1996, but he never really discussed it and that was that. Fast-forward to two weeks ago, when I was surfing the web and reading some of New York Magazines picks for the fall. Junot (we didnt call him Professor Diaz) was interviewed about his new book, and I ignored the possibility of awkwardness just long enough to email it to the class. (Junot is also on the class list. awk) Date: Sat, 25 Aug 2007 From: Mitra Subject: NY Magazine raves To: [emailprotected] http://nymag.com/guides/fallpreview/2007/books/36501/ Hope youre all doing well! mitra Heres a quotation from the article: Díaz, pushing 40 but looking 30, is talking about the eleven years it took him to follow up on his best-selling, six-figure-advanced, award-winning book of short stories, Drownâ€"by most accounts the first great work of Dominican-American fiction. Every now and then you catch one, bro, and I caught a f*cking bad one. At long last, thanks to his gentle agent, his hard-nosed editor, Sean McDonald (who also editedâ€"and survivedâ€"James Frey), a good therapist, and “sheer ornery stubbornness,” his first novel, which fulfills his two-book contract, is doneâ€"and in many ways it’s even better than Drown. Yay. Then, much to my surprise, Junot (sort of) emailed back. Date: Sat, 25 Aug 2007 From: Junot Diaz Subject: And Time Magazine To: [emailprotected] Professor Diaz is away but if youre trading reviews try this one: http://www.time.com/time/magazine/article/0,9171,1655718,00.html Cordially Ysabel de León Assistant to Professor Diaz Heres another juicy quotation for the click-averse: Then Díaz more or less disappeared for 11 years, long enough for most readers to assume that, like most next great hopes of American literature, he wasnt coming back. Now he has, and with a book so astoundingly great that in a fall crowded with heavyweightsRichard Russo, Philip RothDíaz is a good bet to run away with the field. You could call The Brief Wondrous Life of Oscar Wao (Riverhead; 352 pages), out on Sept. 6, the saga of an immigrant family, but that wouldnt really be fair. Its an immigrant-family saga for people who dont read immigrant-family sagas. and my favorite paragraph of the review: Díaz has written Oscar Wao (a mishearing of Oscar Wilde) in a mongrel argot of his devising, a mixture of straight-up English, Dominican Spanish and hieratic nerdspeak crowded with references to Tolkien, DC Comics, role-playing games and classic science fiction. (What more sci-fi than the Santo Domingo? Oscar asks, What more fantasy than the Antilles?) In lesser hands Oscar Wao would merely have been the saddest book of the year. With Díaz on the mike, its also the funniest. As Oscar and Lola grow up and go to college, they find themselves fighting the lingering dooms of the old country, the alien demands of New Jersey and the depredations of their romantic hearts, all at the same time. Its an unwinnable three-front war, and the outcome isnt a fantasy; its brutal reality. You know exactly what kind of world we live in, Díaz writes. It aint no f*cking Middle-earth. Yes, this is pretty much how Junot speaks during class. We then shifted from trading reviews to trading tour info Date: Thu, 30 Aug 2007 From: Brooke Subject: go see Junot!

So if (like me) you now live a little south of Boston David Date: Fri, 31 Aug 2007 From: Louis Subject: Re: go see Junot! To: [emailprotected] Anyone know anything about any California events? Ysabel swoops in again with a lifesaver email Date: Fri, 31 Aug 2007 From: Junot Diaz Subject: Re: go see Junot! To: [emailprotected] Professor Diazs tour schedule can be found at: http://www.newyorker.com/magazine/tnyevents Cordially Ysabel de Leon Assistant to Professor Diaz Um, how hot is it to have your tour schedule posted by The New Yorker? So very hot. Finally came the big one From The New York Times review Junot Díaz’s Brief Wondrous Life of Oscar Wao is a wondrous, not-so-brief first novel that is so original it can only be described as Mario Vargas Llosa meets Star Trek meets David Foster Wallace meets Kanye West. It is funny, street-smart and keenly observed, and it unfolds from a comic portrait of a second-generation Dominican geek into a harrowing meditation on public and private history and the burdens of familial history. An extraordinarily vibrant book that’s fueled by adrenaline-powered prose, it’s confidently steered through several decades of history by a madcap, magpie voice that’s equally at home talking about Tolkien and Trujillo, anime movies and ancient Dominican curses, sexual shenanigans at Rutgers University and secret police raids in Santo Domingo. Who wrote this review? Carrie Bradshaw-hating author and critic Michiko Kakutani. Nice. Do check out both Drown and The Brief Wondrous Life of Oscar Wao. And then laugh at people who think that MIT doesnt have a strong humanities department. (Give them the books too, since that was kind of mean.) Edited to add: Junot Diaz on Charlie Rose!

Global Warming Not a Big Deal - 529 Words

For the past decade or so, global warming has been a topic of debate for people to determine whether it exists or not. I personally believe global warming is a natural occurrence, and the world is going through it’s course as a planet. However, many scientists, researchers, and environmentalists are showing concerns in the fact it does exist. But, there are still few people who disagree global warming is not occurring. I will discuss why I think global warming does not exist, human involvement, and costs and benefits of the topic. Global warming is not as big as a threat as claimed. There is a substantial amount of evidence proving that temperatures have fluctuated for thousands of years. Surface temperature recordings show a warming period from about 1910 to 1940, followed by a cooling period until 1975, and now we are experiencing a slight warming trend, again. In the seventies, scientists even claimed global cooling was occurring! Although there has been an increase in 1 de gree celsius, that is enough to make a difference but not enough to call it global warming. In the past 2 years, arctic ice has also increased by 50%. According to townhall.com, some people have predicted all of the arctic ice would have melted by now. There is an obvious question to all of this, how can we be experiencing global warming where there is in fact, no global warming?

To address these complaints and improve performance of the emergency department the Six Sigma Team must understand process improvement proposals. The process must identify the reason of the bottleneck; identify the correct data collection method; the use of capacity planning; accurate analysis of the scheduling and controlling techniques; and identify a recommendation on staffing or alternative sources of care. Process Improvement Proposals A process improvement proposal is a mechanism to define the opportunities needed to reduce the number of steps, interactions, decision points, reports, and the length of the defined practice (Langabeer, 2008). Three key areas need to be addressed when improving a current practice. According to Langabeer (2008), these areas include increasing capacity, reducing the use of resources, and reducing the amount of variation (p. 79). For example, if the emergency department is currently seeing patients at a rate of four per hour during normal business hours, and this rate drops to one per hour during the period listed a bottleneck will result. To address this issue the department needs to provide the resources necessary to avoid the problem. However, when the reason for the bottleneck is known the correction must include steps to preserve resources. These steps must address reducing the cost per patient, removing excessive steps, and exposures that are unnecessary. Because the data shows the bottleneck occurring after normal business hours the third key area is equally important for successful performance. This area involves the development of control tools. These tools will assist the department when variation occurs, these tools can include the development of contingency plans to use other hospital resources available after normal business hours; for example the use of clinical examination rooms for patient overflow. Process of Improvement Method Edward Deming introduces a method known as the Deming Cycle to identify bottlenecks within organizational structures. The Deming Cycle comprised of a continuous process cycle that involve planning, implementation, assessment and decision-making. Deming postulated that â€Å"business processes should be analyzed and measured to identify sources of variations that cause products to deviate from customer requirement† (Arveson, 1998, para 1). Each step gives operation managers the feedback needed to determine if they are meeting current objectives. Arveson also suggest that this checklist will help reduce bottlenecks from happening while increasing productivity within every department. Comparing the Middleton Hospital use of Six Sigma methodology to Deming Cycle both methods can help reduce bottlenecks issues with waiting time that occurs during interval time of 6:00 p. . to 10:00 p. m. Six Sigma methodology uses phases of defining a problem and provide an alternative solution to the problem. The next phase includes measuring the solution’s outcomes, analyzing the outcomes’ goals and effectiveness, improving any flaws that was identified in the improvement process, and controlling any costs or activities to contain cost and resource deficiency (National Association of Health Care Quality, 2009). The Six Sigma system addresses each problem measuring a quantitative solution to be addressed by upper management and delivered to department heads for implementation. Appropriate Collection Methods Middletown Hospital needs to look at different ways of collecting data. Data collection can be subdivided into three categories with service type, department, and floor. This collection of data is valuable tool that managers need to have in order to understand the flow of business within each department. With the collection of data it will allow managers to calculate the volumes of patients during specific times. The SST will require data collected from all computers used to monitor access to the admission system. Additional data will have specific times at which the patient reported to various stations of treatment, and when the patient was discharged. A multivariate trend forecasting method will be more appropriate in this setting; the use of multiple variables about the item being forecasted allows seasons and cycles to be combined with other variables and improve forecast accuracy (Langabeer, 2008). This will give operation managers better forecasting abilities as they will be able to see trends. Finally, the SST will need to analyze the amount of resources or assets available to serve demand (Langabeer, 2008). Quantitative data needed to measure capacity will include: the number of available beds and treatment rooms, the number of key providers and other staff available at each point of care between 6:00 p. m. and 10:00 p. m. , and availability of key medical technologies and equipment. Examples of key medical equipment are diagnostic imaging, X-ray and laboratory equipment. Methods to Analyze The first step in analyzing the cause of Middletown Hospital’s emergency department bottleneck is to perform a capacity analysis that will help to identify appropriate assets and resources to serve the increased need within each emergency department. The analysis should capture statistical data in time series format that will show sequential data recorded during different time periods throughout the day. Data should be included from time periods when the emergency room is successful in handling demand as well as occurrences of the bottleneck. Creation of a control chart can also be useful in discovering areas of daily operations that are contributing to the current issue of meeting demand. Middletown Hospital is aware that they can not keep up with the demand placed upon each department with current needs. In knowing the limitations, data from the other 20 hours in which emergency department is in operation can be used to obtain values for a mean and average to be used to create a control limit. Taking data from the entire day can be used to obtain a standard deviation value as well. Data and observations that show a large deviation from the mean will alert the staff to areas that need to be updated or streamlined. The control data that is being recorded should be able to define staff ratios, numbers of patients seen, time of day, day of the week, equipment or technology malfunctions, ime of patient visit, reason, and duration. A control chart can help Middletown Hospital distinguish normal and abnormal processes within their patient delivery service. Bottlenecks Operation managers need to handle many different jobs at once. These jobs can be dealing with bottlenecks, and forecasting. Operation managers need to look at current flow of business to determine the proper amount of staffing needed to handle problems in the future. By working with an accurate forecast managers are able to see what is expected and when the flow of business will occur. When increasing staffing in any department the profitability will decrease at start, but soon will rebound as more patients realize they are receiving treatment at a faster pace. According to Langabeer (2008), one of the keys to increase throughput or capacity is to remove these obstacles or bottlenecks, which is called de-bottlenecking (p. 96). Increasing the number of staff on during peak times it will be easy to reduce the number of complaints and increase the profitability of every department. Being able to remove the barriers will allow managers to see the results within days instead of weeks. Within any department comes demand and being able to predict the demand allows managers to become better forecasters. According to Langabeer (2008), â€Å"forecasting is a collaborative process that estimates the volume of patients that will be served over a specific time period. More precisely, it is a projection of demand that will occur along three dimensions: service type, location, and time dimensions† (p. 97-98). Managers will have to better look at the forecasting they are doing in order to make sure they are using the most current data in order to predict flow and handle problems. Recommendation on Staffing Middletown hospital’s ability to move patients smoothly through the emergency department has become a conversation of complaint for patients. Due to the high volume of patients being seen during the hours of 6:00 p. m. and 10:00 p. m. changes need to be made to optimize waiting times and efficiently treat patients. The emergency department is averaging 100 patients per day which, means that 70 of them are coming through the emergency department between 6:00 p. m. and 9:00 p. m. According to Langabeer (2008), in health care, wait times are frequently a source of poor patient satisfaction and process inefficiency (p. 10). The hospital emergency department is currently plagued with a lack of staff scheduled at key times and needs to look at alternatives to better manage the movement of patients. Creating a solution for Middletown hospital means using multiple channel servers to reduce check in time and maximize on hand staff’s time management. Because a majority of the iss ues arise at a key time in the day the revision of the patient routing and flow is required. According to Hall (2006), therefore, by altering patient routing and flow, it may be possible to minimize patient waiting times and increase staff utilization (p. 221). Bottlenecks occur in a hospital emergency department because of the triage concept of putting most significant injuries first. This means many minor care issues will be pushed back. Combating this issue creating a fast track lane to handle minor care issues will decrease patient complaints and wait time. These concepts should reduce the wait time of patients within this three hour block and maximize their experience in the emergency department at Middletown hospital. Conclusion Bottleneck is often the result of an organization lacking the capacity to meet the needs of clients in delivering a particular service. Middletown hospital was given a recommendation to review its current organization capacity by examining their processes, resources, technology. Middletown hospital was able to define other available resources which could be used to assist with meeting their patient demand. Reference Arveson, P. (1998). The Deming Cycle.

Spinoza Essay Research Paper This paper will free essay sample

Spinoza Essay, Research Paper This paper will sketch Spinoza s statement in Part 1 of his Ethical motives of substance. He argues that there is merely one substance, which is the same as God, that includes everything in the existence. It will walk through each proposition and explicate his cogent evidence of it, which relies of his declared definitions. This paper will besides explicate the difference between Spinoza s belief of substance and that of Leibniz from his Discourse on Metaphysics. It will so reason that Leibniz s history of the figure of substances superior. Spinoza s first proposition is that substance is by nature prior to its fondnesss ( Cahn p.417 ) . This proposition relies on his definition of a substance which is self created. The fondnesss of the substance, harmonizing to his definition, are things that are created by something else. Since the substance is self-created, the substance must hold created the fondnesss from itself. Therefore, the substance is prior to its fondnesss since the substance has to be in being to make its fondnesss. Proposition 2, two substances holding different properties have nil in common ( Cahn p.417 ) , besides relies on the definition that a substance is self-created. If one property of a substance is created from that substance, it belongs merely to that substance. Therefore, two different substances holding the same property are non different, but the same substance. If two substances are genuinely different, they have none of the same properties. If all the properties of the two substances are wholly different, they have nil in common. One thing, which is wholly different from the other, can non hold caused the other. This is true because something created must hold some cognition of its Godhead, as stated in Spinoza s axiom 4. Since the two different things have nil in common, which includes no cognition of the other, one can non hold created the other. Spinoza states this in proposition 3. When things have nil in common, one can non be the cause of the other ( Cahn p. 417 ) . He besi des reaffirms this in proposition 4 by saying that things are different by the fact of differences in their properties or fondnesss. This fact is seen easy by looking at the proofs beforehand of propositions 1,2, and 3. Proposition 5 and 6 restate earlier propositions in footings of substances, as opposed to things. Proposition 5 provinces: In the existence at that place can non be two or more substances of the same nature or property ( Cahn p.417 ) . Since two substances are distinguished by a difference in their properties or fondnesss ( proposition 4 ) , the substances would non be different from one another if the had the same property. The two substances would be the same. Proposition 6 provinces that One substance can non be produced by another substance ( Cahn p.417 ) . If a substance were to make another one, they would hold something in common such as an property. However, there can non be two substances with the same property ( proposition 5 ) , they must hold different properties and, hence, be different. If the substances are different, they have nil in common ( proposition 2 ) , and substances with nil in common on could non hold caused the other ( proposition3 ) . One substance can non make another. Spinoza has proved all this about a substance, but has non proved that substance exists. In proposition 7 he does: Existence belongs to the nature of substance ( Cahn p. 418 ) . He states that since substance is self-caused, being is needfully involved in it kernel, intending that being is portion of its nature. Now that substance exists, Spinoza proves it is infinite. He says that if substance were finite, it would be limited by another substance with the same property of being. But no two substances can hold the same property ( proposition 5 ) . Therefore, substance is infinite. Since Spinoza has proved that there is a alone, infinite substance that exists, he now goes on to turn out that the substance is God, merely one of which exists. He must first include some propositions, which will be used subsequently to assist turn out this point. He begins by turn outing that the more existent something is, the more properties it has ( proposition 9 ) . He feels that this proposition is apparent in the definition of an property: that which the mind perceives of substance as representing its being ( Cahn p.416 ) . The more world that is associated with the kernel of a substance the more properties it has because an property is what the mind perceives the kernel of the substance to be. The substance itself must gestate each of these properties ( proposition 10 ) . Harmonizing to definition 3, gestating a substance does non necessitate the construct of something else with which to organize the substance. Besides, gestating something is based on its kernel. Therefore, attributes used to gestate a substance must be conceived through itself. Now Spinoza proves that God exists in proposition 11: God, or substance consisting of infinite properties, each of which expresses ageless and infinite kernel, needfully exists ( Cahn p.419 ) . He easy proves this utilizing axiom 7: if a thing can be conceived as non bing, its kernel does non affect being ( Cahn p.416 ) . He says it is absurd to gestate God as nonexistent since being belongs to the nature of God, or substance ( proposition 7 ) . He besides says that there is no substance that can turn out that God does non be since two different substances have nil in common ( proposition 2 ) . Therefore, God exists. Now that Spinoza has proved that the infinite substance of God exists, he proves that substance can non be divided in proposition 12. He that if it were divided, each portion would be infinite, self-caused, and would hold to hold different properties, doing several different substances to be caused from the one substance which is impossible because no substance can be caused from another ( proposition 6 ) . Proposition affirms that an perfectly infinite substance is indivisible ( Cahn p.421 ) . It is impossible to split an perfectly infinite substance because several substances would be with the same properties, which is impossible harmonizing to proposition 5. Spinoza now proves proposition 14 ; that no other substance other than God exists. Since God is an perfectly infinite being, any other existing substance would hold to exhibit an property of God. This is impossible because no two substances can be with the same property ( proposition 5 ) . Being is an property of God ; hence no other substance can be. Leibniz s place on substance differs form that of Spinoza in the figure of substances. Leibniz does non believe in one substance, but in many substances, or as he calls them monads. He believes that everything is made up of monads with their ain properties. These monads are in harmoniousness throughout the existence, neer coming in contact. He believes that anything thing that consists of monads with the same properties are non different, but the same, similar to the belief of Spinoza. The lone difference is the figure of substances. Leibniz s history of the figure of substances is superior. The many monads, each with its ain properties, allows for the many different things in the existence to be. Since everything does non hold all the same monads, they can be different. A Canis familiaris and a stone are evidently non the same. They are non the same because they are composed of monads with different properties. If they did consist of the same monads, they would be the same, and they evidently are non. Harmonizing to Spinoza, God is the lone substance. Everything we know is portion of God. God includes all properties. If I am portion of God, I contain all properties. However, I do non incorporate all properties. There are many that I do non include such and eternity. I am evidently non infinite. Leibniz s history of the figure of substances allows me to be, non incorporating every property.

Womens Novels free essay sample

Compares novels portrayals of women, Canadian culture, characterizations, world views, settings. The Handmaids Tale ( Margaret Atwood ) Maria Chapdelaine ( Louis Hemon ) There is a wide gulf separating the French-Canadian work Maria Chapdelaine by Louis Hmon and The Handmaids Tale by Margaret Atwood, but there are also certain characteristics linking the two works as expressions of a certain worldview, especially toward the role of women in society. Hmon writes a realistic account of rural life among French Canadians in the early part of this century, while Atwood offers a speculative dramatization of a dystopian society such as might develop in the future if certain trends she perceives in contemporary society continue. One thing that links the two works is a certain view of women and their ability to transcend the roles given them by society, though Atwood is quite self-conscious in presenting this theme while Hmon merely demonstrates an attitude toward women without making it a central or overt issue.

Difficult childrens influence on married life Essays Difficult childrens influence on married life Essay Difficult childrens influence on married life Essay Some of the disablements kids may be diagnosed with are autism spectrum upsets, sightlessness or ocular damages, hearing loss, hearing damages, and deaf-blindness, developmental disablements, larning disablements, mental Illness, and a scope of other disablements. While any kind of disablement can be lay waste toing to a twosome, depending on what type of disablement All of which impact households in a assortment of ways and have different socio-cultural significance to the twosome. For many old ages, scientists have explored how parental struggles and other matrimonial jobs can impact the wellbeing of kids. Far less attending has been paid to the opposite inquiry: How do kids, particularly hard kids, influence the quality of married life? Couples face many challenges in today s society. Pressures to suit into the prefect cast of the happy household are plastered every where we look. Romantic comedies show existent twosomes traveling through break-ups and makeups looking comparatively cursed and believe it or non their job was a misinterpretation. Who knew? However, the twosomes I will be turn toing in this paper do non suit into the perfect cast Couples who have a kid with attending shortage hyperactivity upset are about twice every bit likely to disassociate or divide as twosomes who do non hold kids with the psychiatric upset, harmonizing to a unequivocal new survey that is the first to explicitly research the inquiry. The ground appears simple: Having a kid who is inattentive or overactive can be highly nerve-racking for health professionals and can worsen struggles, tensenesss, and statements between parents. The research subject is sensitive because it can be easy misinterpreted to intend that scientists are faulting childs for the matrimonial sufferings of their parents ; that may be one ground research workers have by and large avoided the subject and limited their probes to how parental struggles affect kids. But progressively, the grounds suggests that the lines of influence run in both waies. The survey, led by psychologists Brian Wymbs and William Pelham and published last twelvemonth in the Journal of Consulting and Clinical Psychology, longitudinally tracked a big figure of households with and without kids diagnosed with ADHD, a upset characterized by inattention and hyperactivity and frequently accompanied by behavior jobs and oppositional behaviour. While 12.6 per centum of the parents of kids without ADHD were divorced by the clip the kids were 8 old ages old, the figure was 22.7 per centum for parents of childs with ADHD. Couples with ADHD childs besides tended to make the point of divorce or separation faster. We have known for a long clip that childs can be nerve-racking for their parents. What we show is they can be truly nerve-racking and can take to matrimonial dissatisfaction and divorce, said Pelham, who works at the State University of New York at Buffalo. What it means is ADHD should non be treated without affecting the parents in the intervention. Pelham said his involvement in the subject was piqued after he conducted a survey that looked into how kids s behaviour influenced the leaning of their parents to devour intoxicant. Pelham had a big figure of parents interact with kids who were non their ain. Some of the childs were trained to move hand in glove, while others were trained to move as though they had ADHD. The parents were given a interruption midway through the session, when they could devour intoxicant, and so sent back in for a 2nd period with the same kid. The parents thought the experiment was mensurating how parent-child interactions changed depending on intoxicant usage ; in world, Pelham wanted to cognize how covering with easy and hard kids influenced the leaning of health professionals to imbibe. The psychologist found that parents indiscriminately assigned to interact with the hard kids drank a humongous 40 per centum more intoxicant during the interruption than parents who were assigned manageable childs. Several old surveies have hinted at connexions between matrimonial wellness and kids s behaviour. Parents of kids with ADHD study less matrimonial satisfaction, fight more frequently, and utilize fewer positive and more negative verbalisations during child-rearing treatments than do parents of kids without ADHD particularly if the kid besides has behavior or oppositional jobs, Pelham and Wymbs noted in their paper. Many other factors influence whether twosomes stay together. Communication jobs, substance maltreatment, fiscal troubles and mental wellness jobs among spouses all play a function in the wellness of intimate relationships. The difference between those other factors and the function that kids play is that the other factors have been widely documented and discussed. Wymbs said that in a separate survey, he brought parents with and without ADHD childs into a research lab. As earlier, he assigned them to interact with kids who were non their ain ; some had been trained to move hand in glove, and others had been trained to move hard. ( The hard childs in the survey were nowhere every bit hard as many childs with ADHD in existent life ; ethical guidelines forbade research workers from developing child histrions to hit or shout. ) Wymbs had the parents and childs perform four exercisings: The first involved playing the game Jenga, which requires strategic thought and planning. Childs trained to be helpful worked hand in glove with the parents ; the childs trained to move hard undermined the parents at every bend. A 2nd exercising called for parents to supervise the childs work outing math jobs while they themselves had to make full out a chequebook, the sort of parallel processing that induces emphasis. The easy childs attended to their prep ; the hard childs refused to make their prep, scrabbling on their documents or wipe outing their replies and blowing the shaves on the parents. In the 3rd undertaking, the childs directed drama. The kid histrions ever chose to play mini-bowling and mini-basketball. The concerted kids took bends and helped put up the games, and the hard kids played out of bend and were riotous. The 4th undertaking involved killing where, as you might conceive of, the kids were trained to be either helpful or unhelpful. Wymbs videotaped the interactions. What he was on the sentinel for was non how the parents interacted with the kids, but how the kids s behaviour affected the manner the parents worked with each other. Regardless of whether they had kids with ADHD, Wymbs found, the parents asked to work with hard kids were four times every bit likely to interchange negative unfavorable judgment and inquiries, or to disregard each other and trade gestural shot, than the parents in the other group. And regardless of whether they were covering with easy or hard kids, parents who had ADHD kids at place were three times every bit likely to be negative toward each other as parents who did non. Put another manner, the parents of kids with ADHD merely had less ability to react to challenges with composure ; they appeared to be psychologically worn thin. Pelham said that although medicines are effectual in turn toing ADHD symptoms, they frequently prove unhelpful when it comes to parent-child interactions because ADHD drugs are stimulations, normally given to the childs in the forenoon before they head to school. The medicine is have oning off by the clip childs get place and have most of their interactions with their parents. It is nt advisable to give kids more medicine because it would maintain them up at dark. Several research workers said parents need to develop behavioural techniques to better get bying accomplishments. When you sit back, you can express joy at it, but in the minute it is phenomenally nerve-racking for the household, said Charlotte Johnston, a psychological science professor at the University of British Columbia, mentioning to the day-to-day challenges that parents of childs with ADHD face. Often the parents have different tolerances for fits. One wants to stand house, but the other is willing to give in. Now the parents are set up to contend, [ stating, ] You Lashkar-e-Taiba him make that? or You are excessively rigorous with him! Johnston teaches parents to acquire on the same page and follow three regulations: The first is to pare down their outlooks and to concentrate on merely one or two job behaviours in their ADHD kid. The 2nd regulation is the familiar parental technique of honoring all positive behaviour and detering negative behaviour, frequently by disregarding it. The 3rd regulation is to systematically lodge with the technique long plenty to see it work. Other experts said it is besides of import to learn parents to take clip to featherbed themselves and put themselves back together psychologically. Many parents do non take attention of themselves. We encourage them to make that even though they may experience they have no clip because of all their committednesss to their households, said Andrea Chronis-Tuscano, a psychologist who directs the University of Maryland s ADHD Program. One of our mantras is, If you do nt take attention of yourself, you ca nt make your best as a parent. hypertext transfer protocol: //www.washingtonpost.com/wp-dyn/content/article/2009/03/02/AR2009030201787.html? hpid=smartliving About 60 old ages ago, I used to watch Roy Rogers and Dale Evans on Television. When I was six, Roy and Dale were the sort of heroes that I needed. I was still larning about the universe, and their show made it easy to state the good cats from the bad 1s. What I did nt cognize back so was that Roy and Dale were besides parents of a badly disabled kid. Their Daughter Robin had Down syndrome with tonss of complications. She merely lived a twosome of old ages, but Roy and Dale loved her and did everything they could to maintain her alive every bit long as they could. Dale was one of the first parents to talk out about being the female parent of a kid with a terrible developmental disablement, in a clip when most parents hid such kids. Roy joined her in stating people that Robin had been a fantastic approval for their household. They were heroes in more ways than one dorsum so, and merely like on their show, it was easy to state who the good cat s were.A Today, life is a batch more complicated. We have new heroes. In a few yearss, Robert Latimer s slaying strong belief comes before the Supreme Court of Canada. Repeatedly we are told that he was a hero for killing his ain kid, for saving her from a life of wretchedness. Peoples tell me that he must hold been compassionate, rational, and brave. Media experts tell me that he must hold loved his girl a batch to make what he did. I guess it s a new millenary and we have different sorts of heroes now.A There is surely no deficit of them. Michael Gentry will be sentenced for nonvoluntary manslaughter of his 15-year-old badly disabled girl in Los Angeles on July 6th. Possibly this excessively was an act of love. Oto Orlik stabbed his 14-year-old badly handicapped daughter more than 30 times before she died in Wisconsin in 1998. How many male parents could be that rational or feel for? Eight-year-old Justin Blair, who was blind and had intellectual paralysis was beaten to decease with a cock by his male parent in New Hampshire.A I can non conceive of the sort of bravery that would necessitate. There are 110 male parents, step-fathers, Foster male parents, and adoptive male parents who are implicated in the homicides of their developmentally disabled kids in our current homicide database at the University of Alberta. These heroes shot, scalded, stabbed, poisoned, electrocuted, starved, round, drowned, hanged, smothered, round and gassed their handicapped kids to death.A One male parent who was enraged because the infirmary would non give his kid the attention that he felt was required, threw the kid out of a 12th narrative window.A Merely a few instances get much attending from the media. Often the sentences are light. In 1984, Louise Brown s male parent killed her and so claimed that his auto had been stolen with her in it. The justice sentenced him to merely five old ages for killing his girl who had Down syndrome because he thought that her male parent might hold been traumatized by holding a handicapped kid. After all, he was no menace to society and a theoretical account citizen, merely another heroic male parent overcome with heartache, who spared his handicapped girl and his beloved household a life of impossible agony. The English tribunals were less forgiving when he came back before them in 1997.A They sentenced him to life for killing his brother by knifing him 63 times.A Dick SobseyA June, 2000 And it is nt merely parents of kids who have ADHD who appear to be more at hazard for divorce.A There are statistics being thrown out at that place for parents of kids who are on the autism spectrum as well.A It seems most people in the autism community are hearing these stats that up to 80 % of parents who have a kid on the spectrum will acquire a divorce.A Yet the beginning of this peculiar statistic is hard to happen as mentioned by Kristina Chew who writes a web log called Autism Vox. A So what is a parent to do of all this? A They are stating us that holding a kid who has particular demands can do emphasis for us parents.A Like Duh.A Tell us something we do nt already know.A Possibly what needs to be discussed are ways of get bying with the emphasis of rearing a kid who requires so much of our clip due to disputing demands and behaviours. A How can parents of particular demands kids trade with this emphasis and come together alternatively of interrupting apart? A A It is my sentiment that one needs to first understand that each parent may manage the challenge of raising a kid who has exceeding demands in really different ways.A I recall a conversation I had with a friend once.A She had a boy who was about my boy s age and this kid besides had autism.A My friend wanted me to talk to her hubby to seek to assist him.A She told me that he merely was nt acquiring it and would non open up about discoursing their son.A I was loath to come in such a state of affairs and asked her what I could perchance do.A She wanted me to give books to her hubby about autism.A I told her that this was something I could decidedly do.A But so she added that the books had to all be positive as he did nt desire to hear anything bad.A In seeking through my books I had a really difficult clip happening any book which depicted autism without adverting any of the challenges or hardships.A When I told my friend of my quandary she told me non to trouble oneself because she d id nt believe he would read anything on the subject anyway.A Clearly they were both fighting in their ain manner. While my friend had already dealt with accepting that her boy had autism, her hubby had non yet reached that stage.A She was researching everything in sight about the subject but he merely wanted to avoid speaking about it because he did nt experience ready.A I ca nt state you how many parents I have talked to where one parent hits the land running by making dozenss of research and obtaining services and therapies and the other parent may still be in denial that their kid needs aid at all. A This difference in where parents are in the procedure of credence can do for some really nerve-racking times.A Both parties can experience entirely in covering with things.A A One parent can hold the position that their spouse is making excessively much, over reacting, or passing excessively much clip with their child.A And the other parent can experience resentful for making so much of the work, experience entirely in their concern, and experience unsupported by their partner.A It is an wholly excessively common scenario being played out in families where kids with particular demands reside. A Rearing a kid with particular demands is non easy on a good day.A And it is even more hard if parents are non on the same page every bit far as credence, outlooks, and programs for the hereafter. A Here are some conversation starting motors to assist bridge that possible spread between you and your spouse in working together to raise your kid: A A What does the disorder/disability/diagnosis of your kid mean to you? A For some parents the diagnosing is confounding and some parents will deny the being of challenges.A For others the diagnosing means worry over the loss of dreams they had for their kid. A One parent I know wondered if their kid who was on the autism spectrum would of all time make normal things like go to the prom, autumn in love, or travel to college.A A parent I know who has a kid with ADHD admirations if this diagnosing will forestall his boy from of all time keeping down a job.A These concerns, frights, and significances attributed to your kid s diagnosing needs to be discussed openly between parents. What is your doctrine of how to assist our kid? A One of the many dissensions which may originate is in the outlooks of any instruction, interventions or therapies.A Some parents strive to assist their kid to go as normal as possible and fit into the mainstream, while other parents veer more towards accepting their kid s restrictions and doing adaptations.A This subject needs to be addressed early on as these differences in outlooks can take to disagree quickly.A What are our restrictions of assisting our kid? A There are some parents who do non believe in any bounds to assisting their child.A They will pass any sum of money, any sum of clip, and will put in any therapy which they believe will assist their child.A I know parents who have spent all their money, have lost their occupations, their friendly relationships, clip with other kids, and some finally lose their partner because no bounds are set on what is done to assist their kid who has particular needs.A These restrictions need to be discussed and agreed upon by parents.A Compromise is critical here. How shall we learn or train our kid? A When you have a kid who has challenges and knows how to force your buttons it is really of import to hold a clear apprehension with your spouse of how to cover with your kid s behaviors.A Professionals can be of great aid here including instructors, healers, and persons trained in behavior direction strategies.A How shall we split up the undertakings needed to outdo aid and back up our kid? A It helps to diminish bitterness if jobs and undertakings related to your kid s attention are divided up.A It gets particularly complex when both parents are working and are pressed for time.A Yet this still needs to be discussed because if one parent feels excessively stressed because they feel that they are making all the work so this bitterness will come out within the relationship.A A It helps to play to the strengths of each parent.A My hubby is better at making physical activities with our boy and enjoys it so he takes him on long motorcycle drives on the weekends.A I like to make more custodies on activities and to learn so I do baking and humanistic disciplines and trades with our son.A When do we pass clip with each other? A Probably the figure one thing I can state you to diminish emphasis within your matrimony is to happen clip to be with each other without kids. A You might experience selfish or even guilty for disbursement clip off but I am stating you that it is necessary.A It is deserving every penny to engage a baby-sitter on a regular footing or happen some kind of reprieve so that you can acquire a break.A Join a gym, travel for a walk, have a repast together, anything which rejuvenates you both.A It ca nt be all about the childs or you will lose your relationship with your spouse.A Make the clip for yourselves and the whole household benefits as you will hold more energy and staying power for when you are with your child.A It does no good for anyone if you are wholly burned out and stressed out.A Remember the old proverb, If mamma ( or dad ) ai nt happy so cipher is happy.

Schoolhouse Lane Estates - Development and Industry Maturation of Wine Term Paper

Schoolhouse Lane Estates - Development and Industry Maturation of Winery - Term Paper Example The demand eventually grew and so Jan decided to operate her own winery. Eventually, Jan became a proud winery owner as what she dreamed about. The business continued to operate and since then Jan was able to encounter expansion of her business at the local wine markets such as wholesalers, retailers, restaurants and caterers. Schoolhouse Lane’s products resulted in net growing revenues. Along with its growth comes the increase on expenses such as on sales and marketing and eventually the spiralling growth of inventories considering that red wines and red wine blends would need a long period of time for ageing in oak barrels. Eventually, Schoolhouse Lane Estates winery is a growing company and is considering rapid expansion as far as there is continued support for its products in the local markets. The case starts with the company history. There is substantial evidence presented about the winery and its evolution which was primarily dated back to Long Island’s Wine Industry in the 1970s. There are also substantial data on Schoolhouse Lane Estates in line with its income statements, balance sheets, and statement of cash flow from 1999 to 2003. The case also cited the information on recent development and industry maturation of winery, the wine production in the United States, the changing dynamics of the US wine market, the competition involved and specific courses of actions made by Jan in order to continue to operate and expand its business. It is clear that the level of analyses that must be involved in the case are combined Level 1 (Industry Issues) and Level 2 (Organization Issues) considering that the demand for wines decreases across California while selling high and eventually more acres of land were converted into fruit trees. This resulted in several wineries gone bankrupt. On the other hand, Jan planned to purchase a new acre of land for her winery  expansion yet considering the Industry’s current trend; it would be a problem on her part to look for sources of working capital as far as her financial options are concerned.  

The woman warrior by maxine hong kingston Essay Example | Topics and Well Written Essays - 750 words

The woman warrior by maxine hong kingston - Essay Example This story is evocative of Chinese patriarchy and a society where a woman in a socially undesirable position finds everything being stripped away from her, including her identity, so that when Kingston’s mother tells her the story, she informs her daughter that â€Å"We say that your father has all brothers because it is as if she had never been born† (Kingston 1). Such is the harsh fate that meets women and her mother uses this story as a basis to caution her daughter against sexual indiscretion, for it is not the man who must suffer the consequences, but the woman. There is no attempt made by anyone in her family to even consider that the aunt could have been a victim of rape or a passionate sexual individualist as Kingston imagines - instead, the villagers attack her family home and humiliate her to the point where her life becomes unbearable and she finally kills herself. The section of the book titled â€Å"White Tigers† is one of the best stories indicating the dichotomy in the treatment accorded to women as opposed to men. Kingston narrates the old Chinese saying which states that â€Å"when fishing for treasures in the flood, be careful not to pull in girls’, because that is what one says about daughters, even when one is in America (Kingston 52). Her own family is no different, because they mouth the same words and prepare the same ink drawings of unwanted little girl babies being pushed down the river with long flood hooks. She remarks with irony that she has read in an anthropology book that the Chinese say â€Å"Girls are necessary too† (Kingston 52-53), but in her own experience, she has not found it to be so. The story of White Tigers is Kingston’s re-telling of the traditional story of the Chinese warrior, Fa Mu Lan, a woman who dons the guise of a man, creating a character who is not limited by the boundaries of her gender. She is a brave swordswoman, and Kingston’s writing brings her fighting skills to life in stunning visuals

Ionic Sieving Properties of Graphene Oxide (GO) Membranes

Ionic Sieving Properties of Graphene Oxide (GO) Membranes ABSTRACT: We characterized the ionic sieving properties of graphene oxide (GO) membranes by performing classical molecular dynamics (MD) simulations. The Lerf-Klinowski model is used for GO nanosheets structure. The Optimized Potentials for Liquid Simulations for all atoms (OPLS-AA) force field is used for GO potential. The SPC/E model is used for water molecules. We show that GO membranes can act as reverse osmosis (RO) membranes, although the water flow in GO membranes is hundred times faster than RO membranes. In this work two important factors in ionic sieving process are studied. First the GO layers separation and second the pressure of water. Each simulation runs until at least half of the water molecules are desalinated. The water flux, permeability, salt rejection, potential of mean force (PMF), and radial distribution function (RDF) are measured. We show that the GO membranes can be the appropriate choice for desalination of seawater in future due to the simplicity in produc tion, low cost, fast water flow, and great ion rejection ability. By 2030 nearly half the global population could be facing water scarcity, with demand outstripping supply by 40 percent, said United Nations Secretary General Ban Ki-Moon.Over 97% of the water on the Earth is saline water and only three percent is fresh water and about two thirds of this fresh water is frozen.So in the near future the only way to provide fresh water is desalination of seawater. There are common ways to desalinate seawater like reverse osmosis (RO) or methods based on distillation. In the RO method an applied pressure is used to overcome natural osmotic pressure so water passes through a semi-permeable membrane leaving salt behind. In the Distillation methods seawater is evaporated and then condensed to produce freshwater. Both methods require a lot of energy and are very costly. Recently nanotube-based membranes and graphene-based membranes have attracted many interests for their potential in water desalination due to their high permeability and great ion rejection. Although these membranes have a great theoretical advantages, the problem of synthesis and fabrication is a major challenge for producing cost effective membranes. Graphene oxide (GO) is a chemical derivative of graphene with several functional groups such as epoxide and hydroxyl that is produced from graphite by the Hummers method. GO has been synthesized and fabricated in the forms of papers and films in the industrial-scale. Functional groups and layers separation of GO membranes can optimized simply during synthesis process to achieve best performance for desalination. In the GO membranes, water molecules permeate through the nanochannels between oxidized regions (pristine regions), which are provided by the hydrophobicity of functional groups. Particles that have a smaller size than the GO nanochannels can permeate in the GO membrane with speed orders of magnitude greater than common membranes. Dry GO membranes have a layers separation of ~5 ±1 angstroms which only lets water vapor molecules permeate through the nanochannels. When a GO membrane is immersed in water, it is swelled so the layers separation is increased to ~12 ±1 angstroms. Na+ is the smallest ion in the saline water which has a hydrated diameter of à ¯Ã‚ Ã‚ ¾9 Ã…. Therefore after swelling of the membrane, small ions such as Na+ can permeate easier which leads to reduction of ion rejection. Several methods have been tried to prevent swelling of GO membranes, such as physical confinement, and crosslinking of nanosheets In this paper we present a next generation of ultrathin membranes which have remarkable abilities like high permeability, good ion rejection, and great resistance to blockage. Furthermore the simple and cheap methods for synthesis of GO membranes make them energy efficient. We performed Classical molecular dynamics (MD) simulations using the large-scale atomic molecular massively parallel simulator (LAMMPS).The VMD and OVITO were used for analysis and visualization. All simulations were carried out in NVT ensemble with a Nosà ©-Hoover thermostat and a damping constant of 10 femtoseconds. The equations of motion were integrated with a time step of 1 femtosecond using the velocity-verlet algorithm. The periodic boundary conditions (PBC) were applied for all three directions. The all-atom optimized potential for liquid simulations (OPLS-AA) is used for graphene oxide (GO) and salt ions.This potential contains many-body terms, including bond stretching, bond angle bending, van der Waals, and electrostatic interactions. In addition, OPLS uses a geometric combining rule for the Lennard-Jones coefficients. The extended simple point charge model (SPC/E) is used for water molecules, following previous studies on similar systems. The force field parameters are given in the table S1 to table S4 completely (see supporting information). The SHAKE algorithm is applied for water molecules to reduce high frequency vibrations that require shorter time steps. The interaction between water and GO includes both van der Waals and electrostatic terms. The van der Waals forces are truncated at 1.0 nm, and the long-range Coulomb interactions are computed by using the particle-particle particle-mesh (PPPM) algorithm. As it is seen in the figure S1 (see supporting information), in our model of GO, both hydroxyl and epoxide groups are considered, following the Lerfà ¢Ã‹â€ Ã¢â‚¬â„¢Klinowski model that is the most well-known model for GO. The structure of the single sheet of GO was considered as 1.5ÃÆ'-3 nm2 containing 18 epoxide and 25 hydroxyl groups. The oxygen functional groups were distributed on both sides of GO sheet. The single sheet of GO contains 206 carbon atoms and 43 oxygen atoms. Therefore, the ratio of C/O is about 4.8 which is in consistent with the Lerfà ¢Ã‹â€ Ã¢â‚¬â„¢Klinowski model. The size of simulation box in the x, y and z directions were about 17, 37 and 11 nm respectively. For preventing the membrane from movement, carbon atoms in the edges of the sheets were fixed. In the first step, a membrane was designed with 13 GO sheets and two layers according to the GO membranes structure proposed in previous studies. Distance between the edges was considered 2 nm. Figure S2 shows the designed membrane (see supporting information). Simulations were carried out for multiple values of layers separation from 7 to 8.5 angstroms with increment of 0.5 angstroms. For each choice of layers separation, three simulations were run for different nominal water pressures of 500 atm, 1000 atm, and 2000 atm. These numbers are nominal pressures but in the feed side of simulation box using voronoi atom volume estimation, feed pressure determined as 600 atm, 980 atm, and 1600 atm. Water pressure on the feed side of the membrane was enforced by applying specified and uniform forces in the z-direction to the piston atoms, thus ensuring that the water pressure was kept constant. Figure S3 shows the membrane with the layers separation of 8.5 angstroms, water, salt ions, and the piston (see supporting information). In the Figure S3a after 0.1 ns water molecules are in the pressure of 2000 atm and in the Figure S3b after 14 ns, we have 94 percent salt rejection and more than half of water molecules purified. In our simulations, saltwater was generated on the feed side of the membrane, consisted of 4800 water molecules and 52 Na+/Clà ¢Ã‹â€ Ã¢â‚¬â„¢ pairs, corresponding to a salt concentration of 35.5 g/L, which is close to the normal salinity of seawater (~35 g/L). Figure 1a shows the flux of water (volume per unit of time per area) passing through the membrane as a function of applied pressure and layers separation. In our simulations, we had to use high pressures in compare to typical pressures that is needed for desalination, because we have a time scale limit in molecular dynamics. We can solve this problem with calculating permeability (volume per unit of time per area per pressure) of membrane that is shown in figure 1b. Another possible method is extrapolating the graphs in figure 1a to low pressures like 10 atm, so we can reach to appropriate flux due to approximately linear relation (R2=0.99). In figure 1b it is obvious that with increasing the layers separation, the membrane permeability increases linearly (R2=0.98). As it is expected the numbers for membrane permeability are in consistent with other reports.Figure 1c shows salt rejection for the membranes with different layers separation and different water pressures. Salt passage wa s calculated from proportion of filtered salt ions number at time t (t is the time that half of the water molecules passed from membrane) to initial salt ions number in the feed side. So we have salt rejection = (1 salt passage). As it is seen in the figure 1c, with increasing the pressure or layers separation, salt rejection reduces which is expected. It is clear that with using lower water pressures like 10 atm, we can achieve higher ion rejection. Figure 2a shows the number of water molecules versus time in the membrane part. For each value of separation there is a limit for number of water molecules that can be in the membrane. In the simulations with higher pressures, the membrane gets filled faster as it is shown in figure 2b. Furthermore in longer times (about 15 ns) the separation value controls the number of water molecules in the membrane. Therefore, without attention to the water pressure, anyway the membrane is filled with water completely. Figure 3 indicates number of filtered water molecules against time. The graphs are plotted at the time that half of the water molecules are desalinated. According to the figure 3b, it is obvious that after about 5 ns the membrane is filled approximately. So we can see a stable flow due to linear relationship between filtered molecules and time. Figure 3a shows water flow for different layers separation and figure 3b shows water flow for different pressures in constant separation value. Figure 4 is the 3D color map for potential of mean force (PMF) for a particle passing through two sheets of GO. The PMF was calculated from steered molecular dynamics (SMD). We used harmonic potential U = K(x à ¢Ã‹â€ Ã¢â‚¬â„¢ x0)2/2, where K is 20 Kcal/mole-angstrom2 and end of spring moving with velocity of 0.00005 angstrom/femtosecond that is enough for reversible pulling. For checking the reversible pulling, the SMD was performed in X direction and -X direction at same width, but the results were same. Also using umbrella sampling and weighted histogram analysis method (WHAM) give us the same results as SMD for PMF calculation. For creating each PMF map, 30 simulations were performed to cover all of the GO layers width. We have done these simulations for 3 different layers separation. So we have a PMF map that shows barriers and valleys of energy all over the GO layers completely. In figure 4a, 4b, and 4c the PMF are plotted for Cl ion that passing from one side of GO layers to another side. In each path, Cl ion sees many barriers that prevent from movement of the ions. Also the ions can stuck in the valleys of energy between the barriers. Figure 4d, 4e, and 4f show PMF map for Na ion. In comparison to Cl ion, the barriers are shorter and valleys have a higher depth. So the Na ions in the valleys can move out with lower energy than Cl ions. PMF for H2O molecule in figure 4g, 4h, and 4i are shown. Flat surfaces indicate easy movement of H2O molecules across GO layers without encountering any barriers or valleys. As we can see in all of the plots, with increasing the layers separation, height of barriers and depth of valleys are reduced so the ions and water molecules move easier. Figure 5 shows salt concentration in the three part of feed, membrane, and filtered against time. In figure 5a the simulation is selected with layers separation of 8 angstroms and pressure of 2000 atmosphere. At the first of all simulations the salt concentration is 35.5 g/lit in the feed part which is same as sea water salinity. Salt concentration of feed part is slightly increased until reach to 90 g/lit at the time that half of the water molecules are desalinated. In the filtered part there are some peaks showing passage of ions through membrane. After the each peak, the salt concentration is reduced until the next peak because of passing water molecules from membrane into filtered part. Salt concentration in the membrane part fluctuates around the mean value of 17 g/lit until the end of simulation. So this fluctuation is enough to ensure that the membrane blockage does not occur even in higher salt concentrations like 90 g/lit. In figure 5b the layers separation is 8.5 angstroms with the water pressure of 2000 atmosphere. As we can see the behavior of plots is similar to figure 5a except number of peaks in the filtered part. Figure S4 indicates radial distribution function (RDF) for water and functional groups in GO layers (see supporting information). Figure S4a shows correlation between oxygen and hydrogen in water. Figure S4b presents RDF between oxygen in water and hydrogen in hydroxyl groups. Figure S4c shows RDF between hydrogen in water and oxygen in hydroxyl groups. Figure S4d shows correlation between hydrogen in water and oxygen of epoxide groups. The first peak in all of the plots in figure S4 shows length of hydrogen bond. As we can see in the figure the longest hydrogen bond is belong to hydrogen of water and oxygen of epoxide. We show that nanometer-scale pores in single-layer freestanding graphene can effectively filter NaCl salt from water. Using classical molecular dynamics, we report the desalination performance of such membranes as a function of pore size, chemical functionalization, and applied pressure.
