Slavery Reparations Are Wrong essays

Subjugation Reparations Are Wrong articles Women and honorable men: I don't accept that anybody in this chamber would move to differ with that servitude was an abomination, submitted from the profundities of the darkest pieces of the human sole. Savagery is the availability to offer torment to other people or absence of worry for their anguish. Relating to precisely what the white man did to the dark slaves. Subjugation was not a foundation of neither prudent nor a paternalistic framework. It was a ruthless, unfeeling maltreatment of humanity. Africans were seized from their local land, and sold into lives of bondage in a remote land. To be sure, it was a disaster on such a scale, that can't be estimated nor evaluated. Furthermore, it is this very idea of catastrophe, which addresses the matter of reparations for bondage. To be very dull, reparations, regardless of whether they might be merited, are not practical under any framework or financial digression. Not exclusively would such an endeavor not cure the circumstance, yet it would sink Africa and her kin more profound into the pattern of neediness and abuse that they have so battled to liberate themselves from. While the contentions against reparations may appear to be shallow or self-serving to promoters of such a framework, upon assessment, the coordinations of what to give, and whom to disperse it to, block any potential advantages of such an arrangement of reimbursement and compensate. The purpose of the accompanying investigate isn't to state that Africans were not abused, nor that they are not deserving of reparations, yet that maybe reparations are not a satisfactory answer for this circumstance, and surely will just serve to exacerbate. Beside any philosophical or thought based contentions against reparations, there exist various strategic boundaries to compensating blacks for their misery. Prompt inquiries emerge in the domain of conveyance - it is natural that such reparations would be hard to disseminate, considerably less to choose how a lot, or where to put the assets or help.

Shape Memory Alloys for Smart Materials- MyAssignmenthelp.com

Question: Discuss about theShape Memory Alloysfor Smart Materials. Answer: Definition of Smart Materials (shape memory alloys) Shape memory alloys (SMAs) are types of smart materials. By definition, smart materials are materials whose properties can react to the changes within their environment. This implies that an external condition, such as pressure, temperature, electricity or light, can change one of the properties of these materials (Roy, 2016). However, the change is reversible. SMA is an alloy that can be folded, twisted or bent into a shape (i.e. get deformed) and return to or regain its original shape when heated above a certain temperature level (Ivanic, Gojic and Kozuh, 2014), as shown in Figure 1 below (GCSEScience.com, 2015). In other words, SMA can remember its original shape. Figure 1: Changes of an SMA Characteristics of Smart Materials (SMAs) Some characteristics of SMAs are as follows: their properties change with changing conditions such as temperature, pressure, light or electricity; change memory effect; they are highly super elastic; they are lightweight; they have high wear and tear resistance; they have high ductile and fatigue properties; their yield strength is relatively low than that of steel but higher than that of aluminium or steel; electrical resistance that changes with temperature; high resistance to vibration; resistance to acoustic damping. Composition of Smart Materials The composition of SMAs depend on the specific type of metals that make up the alloy. The most common SMAs is Nitinol, which comprises of nickel and titanium. Other compositions of SMAs include: copper-aluminium-nickel (Cu-Al-Ni), silver cadmium (Ag-Cd), Au-Cd, Cu-Sn, copper zinc (Cu-Zn), In-Ti, nickel and aluminium (Ni-Al), Mn-Cu, Fe-Pt, among others. These metals are the ones that determine the properties of a particular SMA. Classifications of Smart Materials There are two main categories of SMAs: one way SMA and two way SMA. One way SMAs are those that when they are in their cold state i.e. below temperature at the start of Martensite-to-Austenite transformation (As), they can be stretched or bent while still holding their shape until when they are heated to temperatures exceeding the transition temperature. When they get heated, their shape changes to the original shape. On cooling, they retain their hot temperature shape until they deform again. Therefore the macroscopic shape of these SMAs does not change when they are cooled from the high temperatures. Two way SMA are those that remember two shapes. One of these shapes is when the SMA is at high temperature and the other one is when it is at low temperature. Two way SMAs exhibit shape memory effect when they are being cooled and heated. They can also be manipulated so as to leave some properties they acquire when they get deformed at low temperature during the high temperature phase. But when they get heated beyond a certain temperature level, two way SMAs lose the two way memory effect. When this happens, it is referred to as amnesia. History of Smart Materials According to Shuai, Yen-Yu and Xi (2009), the history of SMAs goes back to 1930s. It was in 1932 when Au-Cd alloys pseudoelastic behavior was discovered by Olander. Greninger and Mooradian then made observations on how martensitic phase formed and disappeared when temperature of Cu-Zn alloy was decreased and increased. A decade later, there was extensive discussion about the fundamental concept of memory effect that was governed by martensite phases thermoelastic behavior. During early 1960s, shape memory effect was discovered in equiatomic nickel and titanium alloy by people working at the U.S. Naval Ordnance Laboratory. This was a major breakthrough in discovery of shape memory materials. The nickel and titanium alloy was given the name Nitinol to mean Nickel-Titanium Naval Ordnance Laboratory. After that, there followed numerous investigations towards understanding the basic behavior of Nitinol and its mechanics. Nitinol, also referred to as NiTi, started being used widely due to its shape memory effect and superelasticity. These two are very new properties in comparison with traditional metal alloys. Production Methods to Produce Smart Materials There are several production methods used to produce SMAs. These include: vacuum melting, induction melting, vacuum arc melting, plasma arc melting, hot and cold working (which comprises of rolling, forging and wire drawing), electron beam melting, rapid solidification methods such as continuous casting and melt spinning (Ivanic, Gojic and Kozuh, 2014). In general, the key processes of manufacturing SMAs are: casting process, heat treatment process, forming process, and machining process (Markopoulos, Pressas and Manolakos, 2016). After manufacturing, the SMAs go through fabrication where they are welded, soldered, joined, machined and coated/plated. Application of Smart Materials in Modern Day Machinery SMAs have a wide range of applications including industrial (automotive, spacecraft and aircraft, and robotics), civil structures (piping and telecommunication), medicine (optometry, dentistry and essential tremor), crafts and engines. Limitations on use of smart materials There are also several factors that limit use of SMAs. Some of these are: response symmetry, response time, functional fatigue, structural fatigue, unintended actuation, high cost, low energy efficiency and limited availability. Future of Smart Materials The future of SMAs is very promising because these materials are expected to be improved further so as to make them better and increase their applications (Weber, 2010). SMAs have great potential of transforming several industries including manufacturing, robotics, healthcare, etc. These materials are expected to find more applications in production of different products used in industries, homes and offices. It is also expected that researchers of these materials will continue developing strategies of overcoming the limitations of SMAs. Additionally, new types of SMAs are expected to be discovered in the near future (Brown, 2015). For instance, there are several ongoing research and development projects exploring the uses of SMAs. Some of these include use of SMAs to make the following products: amplitie, puddlejumper coat, cooling jacket, adaptable airplane wings, automatic rolling shirt sleeves, opaque glass, disappearing ink, etc. (Cooper, 2013). All these products are made by ap plying the fact that SMAs are able to learn and change their properties because of surrounding conditions. If properly used, SMAs can improve the performance of almost all present products including robots, automobiles, airplanes, electrical appliances, etc. (Rossiter, 2017). Therefore as the global population continues to increase and natural resources become scarcer, SMAs are expected to play a major role in coping up with scarcity of resources (Busscher, 2015). In general, SMAs are anticipated to improve the future and those who want to build the future must understand them. Works Cited Brown, J. (2015). Shape Memory alloys Continue to Improve the Future.

Plato Crito free essay sample

Examining Socrates in Crito In the Dialogue Crito, Socrates employs his Elenchus to examine the notion of justice and one’s obligation to justice. In the setting of the dialogue, Socrates has been condemned to die, and Crito comes with both the hopes and the means for Socrates to escape from prison. When Socrates insists that they should examine whether he should escape or not, the central question turns into whether if it is unjust to disobey laws. Socrates’ ultimate answer is that it is unjust; he makes his argument by first showing that it’s wrong to revenge injustice, then arguing that he has made an agreement with the city’s law for its benefits, and finally reasoning that he should keep to that agreement and accept its consequences. However, the examination in Crito was incompletely and its logic flawed; in making this decision, Socrates has forsaken his life for his ideal of justice. We will write a custom essay sample on Plato Crito or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The examination was done in the elenchus, which has the structure that Socrates will start with an assumption and find contradictions to eliminate possible answers; the assumption here is that there are good reasons why Socrates should escape from prison. Socrates starts his argument by first eliminating the public opinion as a reason why he should escape. Socrates observes that concerning a person’s health, only a doctor’s opinion would matter instead of the public opinion; he then draws a parallel of that analogy to justice, that â€Å"We should not give so much thought to what the majority of people will say about us, but think instead of what the person who understands just and unjust things will say † (Crito 48b) While the public opinion would certainly urge Socrates to preserve his life, Socrates discredits it as a reason for his escape. Next Socrates assumes that since only a good life is worth living, and that living a good life is the same as living a just life (Crito 48b), Socrates should escape for his life only if it is just for him to do so. Effectively, Socrates has reduced the question to whether if it is just to disobey the law (by escaping prison and execution) to decide if he should escape. To this question, first Socrates says that he should not revenge injustice. Because doing injustice is bad in any circumstances (Crito 49b), to return injustice just because of having injustice done onto himself would bad also (Crito 49c). Therefore Socrates should not commit injustice just to get even with Athens. Injustice is bad because it harms, and disobedience to the law would harm the city (Crito 50b); so it seems that to disobey the law would be an injustice. But why should Socrates obey the law of the city? Socrates reasons that since the city has done him great benefactions, such as giving birth to his life, taking care of his physical upbringing and his education, and granting him long years of benefits from the legal system (Crito 50e 51c), Socrates owns the state a strong duty of gratitude just as a child would own to his father. One of those duties is to obey the state (like how a child obeys his parents), which always has included the possibility of death such as in times of war (Crito 51b). Socrates should obey the city because he has made an agreement to do so. This agreement is the social contract that he has implicitly accepted and lived under for 70 years. This contract is legitimate because Socrates had a thorough understanding of the legal system (Crito 51e 52a), he did not leave the city when he was given the fair chance all his life (Crito 51 c-e), and that he even has consciously benefited legally from this implicit agreement with law all his life. Therefore it is evident that Socrates has made such a social contract with Athens, which he has been satisfied with so far. It is just for one to keep the agreement he has made, therefore Socrates should keep the agreement made with Athens; and thus he should obey the state and its laws (Crito 53c). Furthermore, Socrates has been given the chance to convince Athens not sentence him to death, and he even could’ve proposed to be exiled that would have the same consequences as if he escapes now; if Socrates had the chance to accomplish thise with legal means when he did not, he would not be justified to do so now illegally (Crito 52c). Following this reasoning, Socrates concludes that he should not escape from prison and his eventual execution. Although Socrates’ commitment to his ideals is admirable, his reasoning is critically flawed. Socrates lacks the definition of justice throughout the discussion of justice. Socrates certainly thinks of justice as something intrinsic and absolute, instead of simply laws imposed by the state; this is evident when he refused to arrest Leon of Salamis by the order of the 30 tyrants (which is an act of disobedience) on the grounds of justice (Apology 32c). Clearly he believes that justice is higher than rulings of sovereignty. But Socrates never made clear what is this virtue that makes justice just; instead, he only vaguely calls some actions just, such as when one keeps an agreement, or behaves well towards one’s parents. It is because of this lack of definition Socrates ends up contradicting himself. For instance, Socrates makes the proposition that one should seek expert knowledge instead of following majority opinion when it comes to justice; this would imply that the justice is not related to the opinion of the majority, as well as that the majority are no expert in justice. If the social contract in the democratic Athens is assumed to be an agreement made between by the majority of the society, then justice is certainly independent from that social contract. But later Socrates argues that he has to obey the state’s laws and keep the agreement made to the state, which implies that justice is to keep the social contract (contraposition of â€Å"not keeping to the contract is unjust†). Furthermore, Socrates assumes that disobeying laws and agreements is unjust. But what is the state? It is no more than a collective of Athenians. Where do these laws come from? The majority opinion of the Athenians (in the case of the tyrants Socrates wouldn’t obey the laws anyways) and the agreements they’ve made. If indeed the laws and agreements the majority of Athenians, it seems that they determine what’s just without knowing what’s just (or else their opinion would matter! ), which would be unacceptable for Socrates. Furthermore, Socrates’ gratitude and duty towards the state does not equate obeying the state; in-fact, if killing Socrates is an injustice that would do Athens harm, then Socrates ought to do whatever that is in his power to prevent being executed by escaping to fulfill his duty of benefiting the city. There is another more fundamental flaw in Socrates’ argument. If he considers justice to be morally independent of laws, then some laws would be just and other unjust. There could be unjust laws, or just laws abused. Socrates never considered these cases of whether he indeed justly deserves the death sentence or not. Therefore to simply obey laws may not necessarily lead to justice. This argument would destroy the whole purpose of obeying laws and not escape from prison. We may speculate, if we have presented these arguments to Socrates, would he be convinced to escape prison? Perhaps not, as Socrates is already 70 and was expected to die soon anyways (the average life span for male was around 40). Dying in the name of justice, instead of old age in a distant place, is definitely more romantic and held more appeal. Furthermore, to live in exile would have no positive effect on his children, it would tarnish his reputation, and such a life in exile will not be enjoyable (Crito 53d – 54d). Therefore, it would be possible that Socrates will still choose to die as a martyr to justice and philosophy.
