Homeostasis in humans - Essay Example Homeostasis includes control of blood water balance, sugar level, temperature and urea in the blood. Cells combine to form tissues which form organs. Fluids contained in the cells are referred to as intracellular fluid while the fluid surrounding the cells are extracellular fluids. Nutrients such as glucose, oxygen and water are supplied through the extracellular fluid. (Chiras, 2003) The main body organs that are used to maintain homeostasis include the brain which has different parts responsible for various body functions, the liver and the kidneys and the skin. To achieve coordination, sensors in the various body organs send signals to the brain. Looking superficially at the functions of these organs as pertains to homeostasis, the brain has three main roles in homeostasis which are executed by the hypothalamus, the autonomous nervous system and the endocrine system which has the pituitary gland as the master gland which controls and oversees the working of all other hormone producing parts of the body. The negative feedback works to maintain an optimum value which represents a set point in homeostasis. When a condition deviates, this corrective mechanism returns it to norm. In order for it to be functional the receptors detect the change while the effectors carry out the corrective measures. The brain is the control centre that coordinates this response. If the deviations are not corrected, further deviation occurs and this is referred to as positive feedback. For instance, glucose is transported to the blood. In case of rise in the blood sugar, for example after a meal, regulation would involve both the pancreas and the liver. In the pancreas, there are Islets of Langerhans which are groups of a special cells that secrete more insulin and less glucagon. For a system to attain a sustainable system, both the negative and positive feedbacks should be present. The lungs homeostatic functions involve regulation of pH and gaseous exchange

Start up of Replacement Ink - Assignment Example The concept of CRM is very closely related to the relationship marketing.

Metabical Analysis Essay Example for Free

Metabical Analysis Essay All other Weight-Loss Options in Exhibit 2 are more expensive that the target $30/ month out of pocket cost. No other weight loss option offers cost containment cards. No other product combines two mechanisms for weight loss: Metabical combines two pharmacologic mechanisms to produce weight loss: Fat blocker, meditonan and appetite suppressant, calosera. Due to the dual mechanism, the medications can be dosed in lower levels and therefore have a better safety profile and fewer side effects than either of the medications that have similar mechanisms, Meridia (prescription appetite suppressant phentermine) or Xenical (originally prescription fat blocker, now over the counter in a lower dose with fewer side effects, Alli) Metabical is dosed once daily, which leads to better patient compliance than over the counter Alli, which must be taken with each meal in order to block fat absorption. Metabical is FDA approved, which demonstrates efficacy and relative safety as compared to over the counter or herbal remedies. Metabical is dispensed by prescription only, which allows physicians to have more control and awareness of what their patients are taking, and to coordinate the use of Metabical with other prescription drugs in a group of patients (moderately obese), who are prone to obesity related disease states, such as heart disease, hypertension, diabetes, sleep apnea, and joint injuries. Metabical is the only prescription weight loss medication with an indication for moderate obesity (BMI 28-30). Other prescription weight loss preparations are indicated for morbidly obese patients with BMI 30. * As a prescription drug, physicians are also able to combine Metabical with nutrition counseling or behavior modification support.

Euthanasia And The Robert Latimer Case :: Free Euthanasia Essay

Euthanasia and the Robert Latimer Case Euthanasia is undoubtedly an issue that plagues the minds of those living with children or adults who are severely disabled. Rarely is one found to have a ‘ neutral' outlook upon it; that is, a side must be chosen, for or against. It is too delicate a topic to be ‘in the middle' about. Over the years, cases involving euthanasia have caused massive controversies as to whether or not it is feasible to take the life of another human being in order to ‘put them out of their misery'. One of the strong questions raised in my mind is: Does the killer really want to put the victim out of their misery? Or is it the killer who is under the extreme pressures of living with the victim, and is it their own lifestyle that they are truly fed up with? In the Robert Latimer case, as in many other cases of euthanasia, it can never be proven whether or not Latimer killed his young daughter Tracy to ‘save' her, or to save himself. While I have never experienced living with someone who is severely disabled, I have had the chance to discuss the issue with many friends and associates. From what I have learned, it is, indeed, an extremely tough matter to deal with. While no-one I have spoken to has been suicidal over the matter, they have seen the true pain and misery that some severely disabled individuals are forced to deal with every day of their lives. Still, many agree with myself on the point that a human life is just that, a human life; and that everyone alive has the right to live, no matter whether or not it is under tougher circumstances than another person. Nobody has the right to take the life of another person, and technically, the law states that nobody has the right to take their own life as well. A severely disabled person may have to deal with much pain in their lives, but they are entitled to the right of simply enjoying being alive, and denying them that right would be an infringement upon their freedom. Latimer should have taken the law into deeper consideration before taking his daughters life. He may have seen the suffering that she went through, but it is evident that he had some sort of strange love for his daughter. Indeed, he did want ‘what was best' for Tracy, but possibly what he was after was what he thought was best. He valued her rights as his daughter, unfortunately he did not value her rights as

Elisa Ans Henry

Describe the relationship between Elisa and Henry at the start of the story, citing examples from the text, and then again at the end of the story. Did their relationship change? How? If not, what might this suggest about Elisa and Henry’s marriage? Based upon my understanding of the reading, Henry and Elisa seemed to have a great relationship. Elisa is portrayed as a rather stern, strong minded, and exacting– to a point type of person. However, Edward appeared to be more submissive and jovial. In essence, Elisa takes on a more masculine role, and she has a peculiar demeanor. † In her tone and on her face there was a little smugness†(Steinbeck, 2011, p. 375). She wanted to know the business that â€Å"those† men had on the ranch. Her reactions to certain situations personified her as very aggressive and masculine. The author signifies evidence of this tone by the way he scripted her response: â€Å"Henry, who were those men you were talking to?! † (Steinbeck, 2011, p. 375). She did not even give him a chance to tell her who they were. Why, sure, that’s what I came to tell you (Steinbeck, 2011, p. 375). At the end of the story, their relationship changed for the best. They actually grew closer despite the polar differences in their personalities. Edward gave Elisa more compliments. He even noticed that a suggestion of movie and dinner brought out the â€Å"feminine side† of his wife– something he had not seen much of. Earlier in the story, she was dress in a very manly hat that covered her eyes, a big corduroy apron, and heavy gardening gloves. As time progressed, Elisa began letting her guard down and became softer, even as soft as the delicate chrysanthemums she nurtured daily. â€Å"He took one hand from the wheel and patted her knee. â€Å"I ought to take you in to dinner oftener. It would be good for both of us. We get so heavy out on the ranch†(Steinbeck, 2011, p. 375). . References Steinbeck, J. (2011). The Chrystanthimums. In D. L. Pike, & A. M.

5 categorías para obtener la green card

Obtener la tarjeta de residencia permanente, tambià ©n conocida como green card, da derecho a vivir y a trabajar en Estados Unidos. Ademà ¡s, si asà ­ se desea, es el primer paso en el trà ¡mite para obtener la ciudadanà ­a estadounidense a travà ©s de la naturalizacià ³n. Cada aà ±o fiscal se tramitan aproximadamente un millà ³n de nuevas tarjetas de residencias. En este artà ­culo se informa sobre las 5 grandes categorà ­as para obtenerla y cuà ¡les son las razones por las que la peticià ³n de la green card puede rechazarse. Conseguir la green card por và ­nculos familiares En Estados Unidos, la mayorà ­a de los migrantes obtienen la green card por peticià ³n de un familiar, que debe ser ciudadano de los Estados Unidos o residente permanente. Los ciudadanos estadounidenses pueden pedir los papeles para sus padres, cà ³nyuges, hijos y hermanos. Los progenitores, esposos e hijos solteros menores de 21 aà ±os tienen la consideracià ³n de familiares directos y la tramitacià ³n se demora, como regla general, en torno a los 12 meses. Sin embargo, las peticiones para hijos casados de cualquier edad, hijos solteros mayor de 21 aà ±os y hermanos se demoran aà ±os, incluso dà ©cadas. Ademà ¡s, en el caso de pedir a un migrante mexicano, la demora es todavà ­a mayor. En todos estos casos el tiempo de espera va a venir determinado por la fecha de prioridad de la solicitud. Por otro lado, los residentes permanentes legales pueden pedir a sus cà ³nyuges y a sus hijos solteros, tanto menores de 21 aà ±os como mayores de dicha dicha edad. El boletà ­n de visas que publica todos los meses el Departamento de Estado es la mejor herramienta para tener una idea aproximada de cuà ¡nto se està ¡n demorando las peticiones para hermanos, hijos casados o hijos mayores de 21 aà ±os de ciudadanos y todas las peticiones de familia efectuadas por un residente permanente. Permiso de residencia por razones laborales Las empresas estadounidenses pueden solicitar una green card para trabajadores extranjeros, siempre que ese puesto de trabajo no pueda ser cubierto por ciudadanos americanos o residentes permanentes legales. Estas son las 100 empresas que mà ¡s patrocinan. Es posible que las empresas no patrocinen directamente la green card. De hecho, un amplio nà ºmero de extranjeros que son patrocinados por una empresa son profesionales titulares de una  H-1B  y que pueden utilizar su visa como trampolà ­n para conseguir la residencia en Estados Unidos. Esta es una de las pocas visas que tiene una naturaleza considerada de  doble intencià ³n. Es decir, en principio se concede por un plazo de  3 aà ±os  que se pueden extender hasta seis, pero durante este tiempo se puede realizar un ajuste de estatus, por razones familiares o laborales, y asà ­ conseguir la  green card.  Pero la H-1B no se convierte jamà ¡s automà ¡ticamente en una residencia, sino que debe haber una peticià ³n de la tarjeta por parte de una empresa. Asimismo, la visa  L-1, transfer entre empresas, tambià ©n es considerada de doble intencià ³n y permite buscar activamente un patrocinador de una green card. Ademà ¡s de esos casos, existen situaciones especiales donde incluso no es necesario el patrocinio de una empresa. Por ejemplo, el caso de personas con habilidades especiales, como artistas, deportistas o cientà ­ficos de gran prestigio pueden autopatrocinarse una residencia permanente mediante la visa EB-1, ya que no hay necesidad de mostrar oferta de empleo previa. Cabe destacar que son casos excepcionales.   Loterà ­a de visas de diversidad para residencia en EE.UU. Cada aà ±o el gobierno de Estados Unidos sortea 50.000 visas de inmigrante conocidas como de diversidad que dan derecho a una green card para la persona que gane el sorteo, su cà ³nyuge y los hijos solteros menores de 21 aà ±os. Se aplica para esta loterà ­a todos los aà ±os al inicio del aà ±o fiscal estadounidense, es decir, en octubre, y sà ³lo se admiten solicitudes digitales. Se prohà ­be que participen los ciudadanos de paà ­ses con altas tasas de inmigracià ³n hacia EEUU. En estos momentos, los siguientes paà ­ses hispanoparlantes està ¡n excluidos Colombia, Ecuador, El Salvador, Mà ©xico, Perà º y Repà ºblica Dominicana. El permiso de residencia para inversionistas Los extranjeros que inviertan un mà ­nimo de un millà ³n de dà ³lares y creen al menos diez puestos de trabajo en Estados Unidos tienen derecho a una visa EB-5 y acabar consiguiendo la green card. La cantidad a invertir puede reducirse a medio millà ³n de dà ³lares, si la inversià ³n se realiza en una determinada à ¡rea econà ³micamente deprimida designada asà ­ por las autoridades inmigratorias. Esta residencia en Estados Unidos es temporal, en el sentido de que pueden ser revocadas si no se mantienen los requisitos de cumplimiento durante cierto tiempo. Tradicionalmente era necesaria una inversià ³n directa, trabajando el inversor en el negocio. Ahora, sin embargo, se admite una inversià ³n indirecta. No hay que confundir esta visa de inmigrante EB-5 con las visas no inmigrante pero que tambià ©n se dan por inversià ³n y que se conocen como E-2, para todo tipo de negocios, o como E-1 para los casos de negocios de importacià ³n/exportacià ³n. Finalmente decir que, en contra de una creencia muy extendida, una inversià ³n inmobiliaria por muy cara que sea no es suficiente ni para obtener la green card por la visa EB-5 ni una visa no inmigrante, a travà ©s de la E-2. es necesario que se trate en ambos casos de un negocio real y activo. La green card por razones humanitarias Las personas que sufran considerable violencia fà ­sica y psicolà ³gica y, al mismo tiempo, ayuden a la policà ­a o a agencias del gobierno estadounidense en el esclarecimiento de un crimen podrà ­an vivir y trabajar en EEUU protegidos por una visa U. Al transcurrir tres aà ±os, siempre y cuando oficialmente se certifique su ayuda en la investigacià ³n o castigo de una actividad criminal, podrà ­an solicitar una tarjeta de residencia permanente. Tambià ©n existe la visa T para las và ­ctimas de trà ¡fico humano y una autopeticià ³n por VAWA para casos especà ­ficos de violencia domà ©stica. Asimismo, cabe destacar el programa de Inmigrantes Juveniles Especiales -SIJ, por sus siglas en inglà ©s- para jà ³venes que han sido abusados o abandonados por uno de sus padres o ambos. En todos estos casos, antes de iniciar cualquier tipo de tramitacià ³n es altamente recomendable asesorarse con un abogado migratorio puesto que si no sale bien la peticià ³n el migrante podrà ­a acabar siendo deportado. Situaciones especialespara sacar la green card Existen otros caminos para conseguir la green card, pero està ¡n limitadas a casos muy especà ­ficos, como por ejemplo los de asilo y refugiados polà ­ticos o el registry, para los migrantes que pueden demostrar presencia continuada en Estados Unidos desde 1972, etc. Problemas para obtener la residencia permanente Reunir los requisitos para poder solicitar el permiso de residencia no garantiza que se vaya a conceder, pues hay causas que obligan a las autoridades migratorias a rechazar  la solicitud de la tarjeta de residencia porque no se cumplen los requisitos para ser admisible para ingresar a Estados Unidos. Cabe destacar que, aunque en la mayorà ­a de los casos es posible solicitar  perdà ³n en los casos de negacià ³n de la peticià ³n de permiso de residencia, es difà ­cil obtenerlo. Ademà ¡s, en muchos casos, incluso no es posible ni siquiera pedirlo. Precisamente porque entender cà ³mo sacar la green card y dà ³nde pueden surgir los problemas es complicado, se recomienda tomar  este quiz - trivial o test- para verificar que tienes los conocimientos bà ¡sicos para obtener y conservar la tarjeta de residencia.   Por à ºltimo, si se està ¡ abierto a la posibilidad de emigrar a un paà ­s que no sea Estados Unidos, estos son 20 paà ­ses con programas de obtencià ³n de ciudadanà ­a y/o residencia a cambio de una inversià ³n. Las cantidades y las condiciones varà ­an enormemente. Puntos clave Se puede sacar la residencia por familia, inversià ³n, loterà ­a, razones humanitarias y otrasMà ¡s de un millà ³n de migrantes sacan la green card anualmenteLos tiempos de demora varà ­an desde unos meses a mà ¡s de 2 dà ©cadasInmigracià ³n no da la aprobacià ³n final a las peticiones de migrantes considerados inadmisibles Este artà ­culo es sà ³lo informativo.

Essay on Character Analysis of Roderigo in Othello

In Shakespeare’s play, Othello, several incidents occur that portray the purpose of Roderigo’s character. If one event is isolated from the rest, the thematic desire is lost. It is only when the events are looked at as a whole that the actual theme is obtained. Roderigo is a minor character who carries out a vital role in the play. Although Roderigo has very few lines, he plays a crucial role on a thematic level. The play begins with a conversation between Roderigo and Iago. The opening lines are significant in that they set the tone and initiate the plot. Roderigo’s thematic purpose is portrayed through Iago’s manipulation in the lines, â€Å"Tush, never tell me! I take it much unkindly/ That thou, Iago, who hast had my purse/ As if the†¦show more content†¦Later on in the play, Iago lies to Roderigo when he tells him that Othello will be taking Desdemona with him to Mauritania. He suggests that if Roderigo ever wants to see Desdemona again he has to make sure that Othello extends his stay in Cyprus. To do so, he suggests that Cassio must be killed, â€Å"Why, by making him uncapable of Othello’s place—/ knocking out his brains.†(4.2.226-227). If Othello goes to Mauritania, Cassio will be assigned Othello’s place. By killing Cassio, Iago gets his revenge and Roderigo would have a chance to win over Desdemona. Roderigo’s character is used to portray the theme of manipulation. He is persuaded into doing Iago’s ill deeds. Iago is only after one thing, to be appointed lieutenant, and he will do whatever is necessary to reach his goal. The theme of jealousy is portrayed through various characters within the play. Iago increases Roderigo’s jealousy of Othello. By reflecting on the jealousy he bears within himself, Iago brings out the jealousy in others. Roderigo sees Othello as an opponent, which he has to compete against in order to win Desdemona’s heart. He expresses his emotions towards Othello when he states, â€Å"What a full fortune does the thick-lips owe,/ If he can carry it thus!†(1.1.67-68). Roderigo says that Othello only got Desdemona out of luck and he will not be able to carry it off. It is because of this jealousy that Roderigo continues to seek Iago’s assistance.
