Blood composition - Essay Example The latter are responsible for giving rise to the blood cells. The mixed myeloid progenitor cells differentiate into the colony forming units (CFU), which ultimately give rise to a particular type of the blood cell. Erythroid cells form the red blood cells which are responsible for carrying hemoglobin and transport oxygen. The white blood cells include monocytes and granulocytes. Monocytes circulate in the blood for some time and then migrate to the tissues to take part in the inflammatory reactions. Three types of granulocytes circulate in the blood, neutrophils, eosinophils and basophils. Neutrophils are the most common among the three. They serve to protect against the infections as they recognize and destroy the foreign antigens. Eosinophils account for 1-6% of the circulating WBCs and are responsible for eliciting allergic reactions and also fight against Platyhelminthes and protozoa. Basophils are involved in hypersensitivity reactions by interacting with IgE antibody. Platelet s arise from megakaryocytes and after activation form fibrin plugs to control abnormal

The House on the Lagoon by Rosario Ferre Essay Example for Free

The House on the Lagoon by Rosario Ferre Essay Rosario Ferre is one of the most noted and famous Puerto Rican writers who have made their mark in the world of literature. Her books illustrate the political and social conditions of her native land. In this paper, we attempt to review and understand her book ‘The House on the Lagoon’ which is extremely famous and provides an interesting insight into the Puerto Rican conditions and the views of the writer as a supporter of feminism.   Ã¢â‚¬ËœThe house on the Lagoon’ was nominated for the National Book Award in 1995. The story revolves around Isabel and Quintin Mendizabal who are a quintessential Puerto Rican couple belonging to the privileged section of this society. The wife, Isabel, has a streak of independence and she feels suffocated in the typically bourgeois environment. She wishes to fulfill her long cherished dream of becoming a famous writer. For the fulfillment of this dream she decides to write a novel based on the life and family history of her husband and herself. However, the husband suddenly discovers the less than flattering description of his family that his wife wishes to make public by getting it published. He is obviously shaken and tries to alter the version that his wife has written in order to make it more appreciative of his family.   The story appears to be simple on the surface. However, while reading it, so many undercurrents appear that it becomes a delightful experience to discover the countless nuances. Many special features and styles of writing adorn the book. The most famous, the most talked about and perhaps the most exciting is the concept of two distinct narrative voices. In the beginning, the book proceeds as a simple family history being retold by a woman. However, a few chapters into the book, suddenly we discover that the narration switches over to the woman’s husband Quintin, who discovers that his wife is writing a novel. Surprises do not cease here. We are treated to another surprise as we discover that the book we are reading i.e. ‘The House on the Lagoon’ is the book that the husband is so incensed on finding. Thereon the narrative continues to switch from Quintin to Isabel and vice versa and this turns out to have far reaching consequences on the novel as a whole.   The double narrative allows for a more democratic unfolding of the story than a single narrative. It allows us to find out Quintin’s reactions to his wife’s narration of his family history. It puts in more animation into a mundane story of family history. Their arguments keep the narration alive and keep the reader guessing at reality and the next sequence of events. Also, there is a marked difference in the ways Quintin and Isabel approach the novel. Quintin, as we are told, has been a student of history in Columbia. To him, misinterpretation of facts and misinterpretation of history is a gross error and in addition, he is extremely embarrassed by the way his family is portrayed in a bad light by his wife. On the other hand, Isabel feels that her main objective is to gain literary fame and she is not concerned with being historically, socially or politically correct. While reading the book, we are thus treated to Isabel’s views and then we read her husband’s comments and views on her writing. This allows for a multiple perspective presentation and the nature of characters becomes more engrossing than the story that they are both trying to tell in their own way.   It has been argued that the dual narrative serves certain higher purposes than simply telling us the dual viewpoints on the story. The dual narrative has been construed as a metaphor for colonization[1]. Rosario’s books usually deal with the conflicts plaguing her native land Puerto Rico, the major one being whether to remain independent or become a part of the US. In the book, through dual narrative, Rosario attempts to bring out this conflict. Isabel, the writer’s alter ego, represents Puerto Rico while her husband represents the dominating influence of the US. Thus multiple perspectives enable the writer to demonstrate Puerto Rico’s quest for identity and her constant struggle against foreign dominance.   Another interesting characteristic of the book is the imagery that is used to illustrate certain finer points[2]. Right from the first scene, where there is a confrontation between the boy serenading Isabel and her fiancà © Quintin, we have a glimpse into the strong characters that we will encounter further on in the book. It also illustrates that Quintin has a violent streak. The relationships between the characters are brought out later in the book. Especially evident is the marital discord between Quintin and Isabel over the issue of her novel which Quintin feels paints his family black. Later in the book, we are provided with another extremely vivid scene which portrays the reason why Isabel is so haunted by her past. Isabel’s mother was forced to have an abortion by her grandmother. This abortion was probably botched and the description of the scene from the child’s point of view sends shivers down the readers’ spine. The gory details such as the pool of blood, the unconscious mother and the dropping of the doll are all images which haunt the reader as much as they must have haunted the young girl. It not only tells us of Isabel’s miserable past but also provides us an understanding of the person she is in the present and why. It also helps us to identify with her dream of making it big as she wishes to escape the drudgery that her female ancestors went through.   Also noteworthy in the novel is the daydreams that Isabel indulges herself with. Her past is so woebegone that she tries to absorb herself in passionate pursuits of her dreams and reveries. These reveries lull us into a false sense of security until the silence before the storm breaks with a shattering incident. This sense of the unexpected renders the narrative far from banal. The most interesting of her happiness and indulgence appears towards the end of the story when she enrolls into a ballet school to fulfill her passion. This dream, like that of becoming a famous writer, reveals Isabel’s desire for fame. She enjoys her dancing lessons immensely and we are again forced to expect some happiness coming her way. However, our hopes are shattered brutally by the public display of pedophilia as the curtain opens at the wrong time during her stage performance. Again, Isabel finds herself abused and unhappy. The ending of the story is thus somewhat tragic and in sync with the mood of the whole story.   In conclusion, it must be said that a subject as ordinary as the relation of family history is made extraordinary by the excellent style of Rosario Ferre and her unique writing style including the double narratives, the imagery and the reveries. Her strong characters help us understand human psyche and also provide insight into the actual political and social problems of Puerto Rico through the characters. In the end, the novel turns out to be more than a story of marital discord or a narration of family history. It helps us to understand history, politics, sociology, psychology and also literature. Few novels are able to achieve such high purpose.

Frederick Douglass :: essays research papers

Frederick Douglass asserts that he, as an adolescent "understood the pathway from slavery to freedom" upon his comprehension of English reading. To contemporary audiences, this may be a hard concept to grasp, an individual reared from birth as a slave understanding the significance of literacy and equating such with freedom. His cognition of this enormous concept can be explained as such: by breaking the literacy barrier, Douglass raised his status (symbolically) from a subhuman, slave status, to human, a White equal. Because all humans are entitled to certain rights, his symbolic progression from slave to human affords those rights, in particular the right to freedom. Slaves were forbidden to read and slave owners were forbidden to teach slaves to read and write. The existence of such a restriction on educating slaves is proof that the slaveholders felt a need to suppress the capabilities of slaves. As a slave, Douglass was given the opportunity to learn and elevate his status only to have all that, including the invitation to join "high" society snatched away. Such a tease and broken promise of a better day proved to be more than Douglass could bear. He devoted each of his idle moments to mastering the language arts. In addition, as if mastering it were not enough, Douglass meticulously educated other slaves in the English language of reading and writing. Douglass' action was indicative of the significance found in literacy. If he had not put literacy at such high esteem, he would not have taken the time to continue his education and persuade others to pursue theirs. Douglass knew first hand that education was a effective tool of empowe rment especially to slaves—those who had spent their lives without any power. This separation of man from education was a control issue and reclaiming control meant education one's self and his or her peers. Through educating his peers, Douglass demonstrated his knowledge of the underlying power in literacy. Douglass practiced not only reading but also writing his English language.

Reconstruction Dbq

The Civil War was one of the most difficult and trying times during American history. The war ended with the the Union and Confederate states torn apart over one major issue: slavery. With the end of the Civil War came the end of slavery in the United States. Although the former black slaves were now free, they had no land and very few rights, and most did not even have family. Though out reconstruction, blacks were able to gain rights, but were continuously repressed by the white Southerners. The only way to truly enfranchise the former slaves was by effectively disenfranchising their former masters.The reign the masters had over their former slaves disabled the slaves from trying to fulfill their lives as equal American citizens. In most cases, the blacks of American were granted certain freedoms and then were taken away or oppressed by the whites. The former plantation and slave owners were not receptive to treating the blacks as their fellow counterparts. As Reconstruction began to start in the United States, the question of how the Southern states would be welcomed back into the Union begged at the issue. Reconstruction started to become a struggle between the executive and legislative branches.Radical Republicans, such as Thaddeus Stevens, wanted to approach Reconstruction from a military prospective because they were seeking revenge and felt the South needed to be taught a lesson because of the havoc and damage that they imposed on the Union (Document A). On the other hand, Andrew Johnson wanted to take a more moderate approach to reconstruction in order to quickly reincorporate the Southern states into the Union. To be allowed back into the Union, as per Andrew Johnson’s plan of reconstruction, the Southern states had to, among many other terms, agree to the 13th Constitutional Amendment that recognized the freedom of blacks.Many blacks felt that they knew their previous masters best and argued that although the states would agree to the recognit ion of 13th amendment, it was only â€Å"lip deep† (Document C). They also argued that the only way to really make the Southerners see the blacks as their equals was with the assistance of the federal government to put military reconstruction into place (Document C). The first Reconstruction act was passed in March 2nd, 1867 and divided the South into five military districts, each under a major general (Document I).In each of these districts, freed males slaves were granted suffrage. This act also offered readmission to the Union if the states ratified the Fourteenth Amendment, which would grant citizenship and civil liberties to all people born or naturalized in the United States. The Fourteenth Amendment was another step toward black equality and secured the rights of the former slaves (Document H). Although blacks were now allowed to vote, whites in the South would use severe intimidation tactics in order to oppress the newly acquired rights of the blacks.Voting is one of the most basic rights of an American citizen, so it would seem that the right to vote for all would equate peace and happiness between the whites and blacks (Document F). The idea of a master seeing his former slave at the same voting polls was an belligerent concept. During this time period, it seemed that the only way for the blacks to have their rights without being oppressed was to disenfranchise the whites. Even though the blacks were released from slavery, the whites still used tactics to keep the blacks in order beneath them.The Black Codes were created to make a cheap labor source for the South. Blacks would be arrested for vagrancy and judged by a jury that consisted of white men; blacks still could not serve on a jury at this time, still displaying that blacks did not receive full rights of white citizens. Thus, blacks would always be convicted by the jury of whites who wanted to ensure a labor force. Once convicted, the blacks were put on farms to work. Blacks would also have to pay a penalty if they were jumping contracts and moving from plantation to plantation; they could not leave the plantation.The whites were basically creating a â€Å"legal† system of slavery, which undermined the blacks newly acquired rights as a free citizen. Andrew Johnson would soon prove to be the oppressor in the fight for black equality during the time of reconstruction in the United States. First, the distribution of land was being brought about by a reconstruction-made institution, known as the Freedmen’s Bureau. The Freedmen’s Bureau provided food, clothing, education, and land to the blacks. By June 1865, the Bureau had settled nearly 10,000 black families on their own land, which was abandoned plantations.Just as the blacks were coming into and accepting their new freedom, the Southern white plantation owners were returning and demanding the return of their land. Andrew Johnson would support their demands and the government would eventually re turn all of the land. Just by this instance, it was proved that the whites in the South had tremendous control over the blacks and the government seemed to be supporting them. The North actually feared the potential power of the South in the most recent events of oppression (Document G). Andrew Johnson was also presented with the newly created Reconstruction Amendments, all of which he vetoed.Although he was overridden by Congress, this shows how the â€Å"white men† has once again oppressed the blacks. Also, Andrew Johnson would soon pull the institution of the Freedmen’s Bureau. This was once again preventing the blacks from bettering themselves as individuals and accepting their new rights and freedoms as citizens of the United States. Tensions ran extremely high between the whites and blacks that it started to become deadly. Hate groups were beginning to form in order to undermine the blacks where they were the majority. The most prevalent hate group was the Ku Klu x Klan.These groups policed themselves in groups around voting polls in order to keep the blacks from exercising their rights given to them in the Fifteenth Amendment. The treatment these hate groups, including the Knights of the White Camellia, oppressed the blacks from exercising the most basic of their civil rights and began to return them to their previous way of life. The hatred and means to put the blacks down was beginning to become incredible because the whites did not want to see blacks become their equals and wanted no help or interaction with their former chattel (Document B).Segregation in the South was becoming more relevant during the time of Reconstruction. At first, there were public areas, such as schools, that accepted both black and white children. Even with such established integrated public places, white Southerners still refused to send their children to school with black children. The court case Plessy v. Ferguson made the term â€Å"separate but equal† sanctified in Supreme Court. This means that black and white accommodations had to be equal, but permitted to be separated.This case also established the Jim Crow Laws, which made the segregation of the races possible. In all reality, although Plessy v. Ferguson determined that black and white accommodations were separate but equal, the accommodations of the whites were of higher standards than those of the former slaves. The segregated and racist mindset of the whites in the South made it hard for the former slaves to make any progress because every step the African Americans took toward securing their civil liberties, the whites were there to take a stand against them by any means.Fredrick Douglass believe that all people in the South could live together in peace if the South merely cooperated (Document D). The Election of 1876 would be the death of Radical Reconstruction. After a discrepancy with the votes in the election, a compromise was made that would make Republican Rutherf ord B. Hayes the presidential winner. The victory of the Republican party would then mean that the Union army must pull out of the five Southern regions. Thus, the Freedmen are now turned away from by the Radical Republicans and are left for the Southerners to handle.The Southern whites will continue to oppress the former slaves and will try to take away every right they have come to gain. The only way for the Freemen to become rich with their civil rights and able to express them would be to take the opportunities away from the whites to oppress them. If the oppression of the blacks by the whites is continuously ignored, then it will be impossible for the blacks to even become completely equal with the whites among them.

Riordan Manufacturing Legal Review

Riordan Manufacturing Legal Review Cody Morse BSA310 10/29/12 Morris Polston Riordan Manufacturing Legal Review Upon reviewing Riordan Manufacturing’s legal section I found the page to be devoid of any information regarding to current business system. However, the page does detail the relationship between Riordan Manufacturing and their legal partners, Litteral & Finkel, who have been legal representatives of Riordan Manufacturing since the company’s founding.Litteral & Finkel are global but lack an office in China to directly assist Riordan Manufacturing on its legal matters regarding their future expansion into Shanghai. The Legal page contributes information regarding the board of directors and the basic governing policies regarding it. Litteral and Finkel have stated that they can send attornies from their closest offices to help aide Riordan Manufacturing should the need arise.Although this is helpful and most useful it would be great to see a virtual meeting syste m incorporated into the communication between both parties (Apollo Group, Inc. , 2012). It is would recommend that both Riordan Manufacturing and Litteral & Finkel, invest in the implementation of a virtual meeting software such as Citrix Go-to-meeting. This would allow for face to face video communication regarding legal matters and would also facilitate realtime document sharing between the parties.An issue with security has also been found during the review. A memorandum was marked confidential however it was protected by any incription. We can see no security measures to protect information internally or externally. It is our recommendation that firewalls be added to all locations to protect from outside interference. It would also be wise to start using a program like Bitlocker on all hard drives.
