A Review Of The Battle Of Lz Albany History Essay

A Review Of The Battle Of Lz Albany History Essay The battle in review is LZ Albany. This battle took place during the Vietnam War under Operation Pleiku. LZ Albany was an ambush on American troops en route to landing zone Albany by NVA regulars. The battle took place on the afternoon of November 17, 1965. The fight involved the US Army 2nd battalion of the 7th Cavalry (2/7) and the NVA 8th battalion of the 66th Regiment. Although the end result of the battle is considered an American victory, the losses suffered were horrendous. It is safe to say this was a pyrrhic victory for the US, only due to the fact that they held the ground at Albany at the end of the battle. This did alter the amount of troops the NVA could attack LZ Columbus with as a side effect. The battle itself would teach many lessons to the US army in regards to the importance of security and the role support by fire played in this theatre of combat. The Vietnam War was a civil war in which the United States was actively involved in. The Northern faction of Vietnam adopted Communism, and thus gained Russia and China as allies. Vietnam until this point was a French territory which was in the process of being liberated by the North Vietnamese. They had defeated France and driven them from parts of the country. France and South Vietnam sought aid from the United States. In reply the United States rendered aid and advisors to South Vietnam. This was due to US foreign policy at the time and staunch opposition to Communism by the US government. If Vietnam fell to Communism it also posed a great economic threat to US interests in South Asia as well. By 1965 the US Armed Forces no longer played the role of advisors for the South Vietnamese in the Vietnam conflict. We were at the point of actively engaging the North Vietnamese in combat. (Stewart 386-320) Under Operation Pleiku, US Army divisions were first employed against the North Vietnamese. This is exactly what the North Vietnamese commander Gen. Nguyen Chi Tranh had desired. His main strategy enc ompassed liberating a vast majority of South Vietnam from southern control and inflicting mass casualties on US forces. The idea was that the American public would not support a war in which multitudes of American soldiers lost their lives. His intent was to shatter the American public’s support and thus drive another foreign imposer out of the country. This plan was titled the Dong Xuan Campaign. (Coleman.51) American forces had already been occupying the provincial capital of Pleiku. Frequent attacks and skirmishes by the NVA gave the impression that they were probing for the best possible place to attack to retake the city. This indicated to US commanders that there was a sizable force of enemy soldiers in the Northern plateaus that needed to be dealt with. A series of landing zones were reconnoitered for probable attack positions. The Army’s objective was simple: to destroy the enemy threat in the area and their will to fight. After securing LZ X-ray, it was the jo b of the 2/7 Cavalry to sweep the gap between LZ X-ray and LZ Columbus, which held US artillery. Their mission was also very simple: to sweep the area between LZ Columbus and LZ Albany, and engage whatever enemy they found.

Embryo Gene Activation Essay Example | Topics and Well Written Essays - 1000 words

Embryo Gene Activation - Essay Example Embryonic genes, which are active prior to the 4-cell stage, are small in number and they code for proteins used in controlling and stabilizing maternal mRNA and proteins. Parental proteins regulated at the post-translational glassy by adjusting the proteins phosphorylation form. Alternatively, these protein states created by the embryonic kinases can stimulate the activities of proteins and change their cell location. For embryo development, change and degradation of maternal mRNA proteins are crucial just before the embryo gene activation. This paper discusses embryo gene activation, DNA repair and the pathways involved in the processes (Lauritzen 240). During the 4-cell phase of embryo gene activation, remodeling of chromatin, which allows transcription of the embryo, and hence synthesizing the translation machinery. The genome of embryos becomes active and starts transcription of metabolic, apoptosis and cell cycle protein regulation (Khanna &Yosef 119). The proteins for maternal mRNAs continuously reduce in the early phases of the 4-cell phase. Signaling pathways for embryonic gene activation example is the hedgehog signaling. The signaling pathway that transfers information to embryonic cells helps for right development. Each part of the embryo can contain different concentrations of these signaling proteins. Not only in embryonic cell development, this kind of pathway has a bigger role in adults and malfunction can cause diseases like, basal cell carcinoma. This signaling pathway is a focus regulator in most animals’ growth (Song & Lee 48). In some other animals, lack of this pathway can lead to poor development of the brain, lungs, and the skeleton. Hedgehog signaling is crucial in regulating the maintenance and regeneration of most adult cells and tissues. Pharmaceutical companies have associated this pathway as a cause of cancer and developed drugs to cure the signaling causing diseases (Polin, William, & Steven 58). Breast cancer susceptibilit y gene 1 (BRCA1) and BRCA2 are genes which suppress tumor and the mutant phenotypes that predispose to both ovarian and breast cancers. These proteins are involved in most cellular processes and contribute DNA repair and regulation in response to the damage of DNA (Ensley 113). BRCA proteins protect the genome from damage by providing maintenance of the stability of chromosomes. The big number of cellular proteins, which interact with the BCRA, propels most functions of the BRCA proteins and their functions linked to different phosphorylation events. Reasons why these proteins cause both ovarian and breast cancer are unknown today (Knobil, Jimmy & Neill 69). These proteins are present in breast cells where they help repair the damaged DNA or destroy the cells in cases where the DNA is unrepaired body (Alpi, Pasierbek, Gartner & Loidl 16). Damaging the BRCA1 by any chance causes the damaged DNA not repaired and this may increase the chances of cancer. Most mammals have complex mechan isms to monitor damage of DNA and the required responses to maintain their integrity and repair. Some of the mechanisms for detection, repair, and cell cycle arrest to prevent damage from gametes or embryo cells (Gordon 670). The repair of the DNA in these newly formed embryos relies on the mRNA proteins from prior ovulation. These repair genes developed in the early stages of the animal development need to be enough to equip the embryo with the maternal products for the gene expression to start at the right

Individual Paper on Accounting Profession Essay

Individual Paper on Accounting Profession - Essay Example There are lots of information assets that have to be protected within the information system of an enterprise. The purpose of this paper is to describe the controls for information technology (IT) reporting and evaluation. One of the most valuable information assets that must be safeguarded is the employee personal files. The law protects the employees and it is the duty of the company to have 100% assurance that this information is not leaked or fall into the wrong hands because the workers could become victims of identity theft. There are two facets to protecting the personal files of employees. The first aspect is the manual paperwork that most companies keep with employee information. Those files cannot be kept in filing cabinets where anyone could have access to them. These files must be kept in a separate room that is locked at all times. The only persons that should have access to the information are the director of human resources and his or her staff. The second aspect of sa feguarding this important information asset is the protection that needs to exist within the computerized information system of the company. The computerized information system of a company must be divided in modules. Each module should be independent of each other. For instance engineers would not have access to the accounting module and vice versa. ... erk with the level of clearance system would be a low level clearance employee which means his access within the accounting module of the information system would be limited to the payable work the person performs for the company. â€Å"Two major reasons why we need to protect information assets are (1) the potential for compromises of such assets, unintentionally or otherwise, and (2) compliance with regulatory requirements concerning information protection and communication (Raval & Fichadia, 2007). There are certain information assets that are so valuable companies that to take extreme measures to protect them. An example of such an asset is patents. Any paper work of a patent should be kept in a safe in the office of the chief executive officer (CEO). The CEO should then decide which employees can be given access to that privilege information. In terms of any digital information concerning patents the system of establishing clearance that gives access to the system is a good way to ensure the information is not leaked into the wrong hands. The top level of clearance within the information system of a company should be given to the CEO and the board of directors. The executive managerial staff would fall to the next level of clearance. The managers or directors of different department would have maximum clearance within their pertinent modules such as accounting, marketing, human resources and engineering, but they would not have full clearance for other modules within the system. It is imperative to avoid compromises of the IT system. An example of a compromise would be the unlawful entrance of a hacker into the information system of the company. If an attack occurs the entire system becomes compromised. At that time the IT department has to take measures to find out
