The Eyes essays

The Eyes essays The eye houses 70% of all sensory receptors of the body. At first glance, the eye seems to be a simple structure, but it is very complex. The actual eye or eyeball is a hollow sphere consisting of many parts. The structure includes the ora serrata retinae, ciliary body, suspensory ligament, cornea, iris, pupil, anterior pole, anterior segment, lens, the scleral venous sinus, the posterior segment, the sclera, the choroid, the treina, the macula lutea, the fovea centralis, the posterior pole, the optic nerve, the central artery and the vein of the retina and the optic disc. Each of these performs a unique function. When abnormalities occur, the result is a vision problem, disease or blindness. The vascular tunic or uvea is the middle coat of the eyeball. It has three regions called the choroid, ciliary body and the iris. The choroid is a dark brown membrane that provided nutrition to the eye tunics. The ciliary body is a thickened ring of tissue that encircles the lens and consists of muscle bundles. The iris is the colored part of the eye, which is the visible portion seen and referred to as a persons eye color. It is shaped like a flat doughnut and is located between the cornea and the lens. The pupil is the round central opening of the iris and allows light to enter the eye. The retina also known as the sensory tunic consists of two layers, a pigmented layer and a neural (nervous) layer. The neural layer of the retina plays a direct role in vision. It is composed of three types of neurons: photoreceptors, bipolar cells and ganglion cells. Rods and cones are found in ural retinas. Rods aid in our dim-light and peripheral vision while cones aid in our bright light and high color vision. There are also various chamber and fluids within the eye, which aid in proper vision and prevention of disease and blindness. The lens is the biconves, transparent, flexible structure of the eye that can change shape and ...

Battle of Guilford Court House in the American Revolution

Battle of Guilford Court House in the American Revolution Battle of Guilford Courthouse - Conflict Date: The Battle of Guilford Court House occurred on March 15, 1781, and was part of the southern campaign of the American Revolution (1775-1783). Armies Commanders: Americans Major General Nathanael Greene4,400 men British Lieutenant General Lord Charles Cornwallis1,900 men Battle of Guilford Court House - Background: In the wake of Lieutenant Colonel Banastre Tarletons defeat at the Battle of Cowpens in January 1781, Lieutenant General Lord Charles Cornwallis turned his attention to pursuing Major General Nathanael Greenes small army. Racing through North Carolina, Greene was able to escape over the swollen Dan River before the British could bring him to battle. Making camp, Greene was reinforced by fresh troops and militia from North Carolina, Virginia, and Maryland. Pausing at Hillsborough, Cornwallis attempted to forage for supplies with little success before moving on to the forks of Deep River.   He also endeavored to recruit Loyalist troops from the region. While there on March 14, Cornwallis was informed that General Richard Butler was moving to assault his troops. In actuality, Butler had led the reinforcements that had joined Greene. The following night, he received reports that the Americans were near Guilford Court House. Despite only having 1,900 men on hand, Cornwallis resolved to take the offensive.   Detaching his baggage train, his army began marching that morning. Greene, having re-crossed the Dan, had established a position near Guilford Court House. Forming his 4,400 men in three lines, he loosely replicated the alignment used by Brigadier General Daniel Morgan at Cowpens. Battle of Guilford Court House - Greenes Plan: Unlike the previous battle, Greenes lines were several hundred yards apart and were unable to support each other. The first line was comprised of North Carolina militia and rifleman, while the second consisted of Virginia militia situated in a thick forest. Greenes final and strongest line was comprised of his Continental regulars and artillery. A road ran through the center of the American position. The fighting opened approximately four miles from the Court House when Tarletons Light Dragoons encountered Lieutenant Colonel Henry Light Horse Harry Lees men near Quaker New Garden Meeting House. Battle of Guilford Court House - Fighting Begins: After a  sharp fight which led the 23rd Regiment of Foot advancing to aid Tarleton, Lee withdrew back to the main American lines. Surveying Greenes lines, which were on rising ground, Cornwallis began advancing his men along the west side of the road around 1:30 PM. Moving forward, British troops began taking heavy fire from the North Carolina militia which was positioned behind a fence. The militia was supported by Lees men who had taken a position on their left flank. Taking casualties, the British officers urged their men forward, ultimately compelling the militia to break and flee into the nearby woods (Map). Battle of Guilford Court House - Cornwallis Bloodied: Advancing into the woods, the British quickly encountered the Virginia militia. On their right, a Hessian regiment pursued Lees men and Colonel William Campbells riflemen away from the main battle. In the woods, the Virginians offered stiff resistance and fighting often became hand-to-hand. After half and hour of bloody fighting which saw a number of disjointed British attacks, Cornwallis men were able to flank the Virginians and force them to retreat. Having fought two battles, the British emerged from the wood to find Greenes third line on high ground across an open field. Charging forward, British troops on the left, led by Lieutenant Colonel James Webster, received a disciplined volley from Greenes Continentals. Thrown back, with heavy casualties, including Webster, they regrouped for another attack. To the east of the road, British troops, led by Brigadier General Charles OHara, succeeded in breaking through the 2nd Maryland and turning Greenes left flank. To avert disaster, the 1st Maryland turned and counterattacked, while Lieutenant Colonel William Washingtons dragoons struck the British in the rear. In an effort to save his men, Cornwallis ordered his artillery to fire grapeshot into the melee. This desperate move killed as many of his own men as Americans, however it halted Greenes counterattack. Though the outcome was still in doubt, Greene was concerned about the gap in his lines. Judging it prudent to depart the field, he ordered a withdrawal up Reedy Creek Road towards Speedwell Ironworks on Troublesome Creek. Cornwallis attempted a pursuit, however his casualties were so high that it was quickly abandoned when Greenes Virginia Continentals offered resistance. Battle of Guilford Court House - Aftermath: The Battle of Guilford Court House cost Greene 79 killed and 185 wounded. For Cornwallis, the affair was much bloodier with losses numbering 93 dead and 413 wounded. These amounted to over a quarter of his force. While a tactical victory for the British, Guilford Court House cost the British losses they could ill-afford.   Though unhappy with the result of the engagement, Greene wrote to the Continental Congress and stated that the British have met with a defeat in a victory. Low on supplies and men, Cornwallis retired to Wilmington, NC to rest and refit. Shortly thereafter, he embarked on an invasion of Virginia. Freed from facing Cornwallis, Greene set about liberating much of South Carolina and Georgia from the British. Cornwallis campaign in Virginia would end that October with his surrender following the Battle of Yorktown.

Compare and contrast the regional variations that are prevalent in the Research Paper

Compare and contrast the regional variations that are prevalent in the Romanesque Church architecture of Lombardy, Germany and the Low Countries, and Tuscany Give examples - Research Paper Example This style of construction and building can be identified in almost all parts of Europe. The most notable buildings that are still standing presently are the churches, with some of these being the large cathedrals and abbey churches (Jackson 32-34). According to Fletcher (25-27), the church was the ultimate emblematic structure of the Romanesque architecture, and since they were constructed to meet specific needs of liturgy, their construction was depended on the needs. These churches had similar architectural designs that included the thick walls semi-circular arches, towers, roofs and round arches in arcades, doors, windows and vaults (Jackson 36). However, these churches differed in the ground plans, the shape and position of towers, shape of columns, piers and the east end, and the building materials (Fletcher 28). This paper seeks to give the similarities and differences between the Romanesque Church architecture of Germany and the Low Countries, Lombardy and Tuscany. The Romanesque architects constructed myriad buildings with most of them being abbey and village churches, castles and cathedrals (Itcher 23). All these churches were constructed to shelter, welcome and hold the faithful in an environment that was dignified and gave a sense of depth and an ambulatory apse (Flecher 31). The Romanesque churches were built with an interior that was complex and with a densely molded material typified by strong chiaroscuro differences that strengthened the plastic outlines of the columns and heightened the sense of encrusted distinctive thickness and spatial depth (Jackson 44-45). From a structural standpoint, this was successful due to the implementation of the system of anchorages taken as longitudinal units; they were made to be spatial bodies that were added to the next one in a symmetrical manner (Icher 49). The buildings had an isolated crossing that was a normal aspect

NPS Deploying network policy server Essay Example | Topics and Well Written Essays - 2000 words

NPS Deploying network policy server - Essay Example Each and every employee in the organization who participates in project implementation has the responsibility do so. Because of the reason above, the best way in ensuring data security in for one central park and at the same time being economical to the company is by investing it the team’s technology. Technology is very dynamic and new things come every other time. When a principle instructs the vendor to direct or educate the employees on information system security the concerned employees feel that their contribution to the company is valued. The information security system that is supposed to be implemented in a bank must take in consideration the four major principles of information security. These are information confidentiality, integrity, authenticity and availability. Information confidentiality is whereby the information of a company is protected from getting into the hands of people who are not authorized. Integrity is a security factor that stops undetected modific ation of data for example the issue of students examination result cannot be modified or edited by unauthorized person because it is only the examination coordinator that have the right of doing editing it. The integrity is breached when anybody who is not an exam coordinator make an amendments. Authenticity means that particular information that is used for a certain purpose is genuine. The validity of individual that get access to some data is ensured by using authentication methods for example he use of password. The security of information that goes via internet is aided by ensuring that the channel that it goes through is the right one (Mueller, 2011). This is by use of IP address that is assigned to each computer. Availability means that the information is accessible anytime the users want. The paper gives details on implementing Network Policy Server in one central park. Security vulnerability Servers are network-based. This exposes all the data it contains to network attacks . A network attacker can use the exposures in the protocols that are ranked high and stronger applications to cultivate the disadvantage that are not checked by the firewalls that are of previous version. The access may prove dangerous as the client data would be reviewed during the transfer to a third party and it would be difficult to track as the activity is a part of the process created for a particular server and hence the severity of this activity is high. Considering the fact that only the users that are involved into this activity will have access to the transferred data, the likelihood of any intrusion is moderate. Database server that stores employee information uses student’s identification details as the only form of security. A password cracker that can overcome the technology used in designing the password can get access to the employee information. More so, database administrator’s password can be cracked and modification. Company’s information fo r example policies can create a mess in the institution. Super user privileges grant a great amount of power to any party who has access to the super user account. If an aggressive party is able to access a super user account on the database server they will be able to copy. The wireless access point devices are vulnerable to physical damages for example fire or theft. This will lead to denial of services in the entire department that

FDI provide opportunities to host countries to enhance their economic development and opens new opportunities to home countries to optimize their earnings by employing their ideal resources. India ranks fifteenth in the services output and it provides employment to around 23% of the total workforce in the country. The various sectors under the Services Sector in India are construction, trade, hotels, transport, restaurant, communication and storage, social and personal services, community, insurance, financing, business services, and real estate. Meaning: FDI stands for Foreign Direct Investment, a component of a countrys national financial accounts. Foreign direct investment is investment of foreign assets into domestic structures, equipment, and organizations. It does not include foreign investment into the stock markets. Foreign direct investment is thought to be more useful to a country than investments in the equity of its companies because equity investments are potentially hot money which can leave at the first sign of trouble, whereas FDI is durable and generally useful whether things go well or badly. Classifications of Foreign Direct Investment FDI is classified depending on the direction of flow of money. * Outward FDI:Any investment made by a country in other countries will account for outward FDI.

FDI IN INDIA After getting independence in 1947, the government of India envisioned a socialist approach based on the USSR system to developing the country’s economy. The last decade of the 20th century witnessed a drastic increase in foreign direct investment (FDI), accompanied by a marked change in the attitude of most developing countries towards inward investment. FDI flows have grown in importance relative to other forms of international capital flows, and the resulting production has increased as a share of world output.. FDI in India has in a lot of ways enabled India to achieve a certain degree of financial stability, growth and development during recession. This money has allowed India to focus on the areas that may have needed economic attention and address various problems that continue to challenge the country. The factors that attracted investment in India are stable economic policies, availability of cheap and quality human resources, and opportunities of new unexplored markets.

Deception in Shakespeares Othello :: GCSE English Literature Coursework

Deception in Othello  Ã‚   In the play Othello, the very evil and conniving character Iago deceives the main characters. He prays mostly on the main character Othello. Othello is a black general who is married to a white woman named Desdemona. In the beginning of the play Othello promotes a man named Cassio to be his right hand man in his army. Iago, thinking that he was going to get the promotion, is furious by this and swears revenge on Othello. In his revenge he uses many people. One of these people is Rodrigo. He is in love with Othello’s wife Desdemona. Iago prays on Rodrigo and causes him to have a battle with Cassio. Iago prays very heavily on Othello towards the middle of the play. He begins to tell him that his wife Desdemona is cheating on him with Cassio. Iago plans this perfectly. Iago tells Othello to keep close watch on his wife Desdemona. At the same time he told Cassio to be very good to Desdemona. Iago tells Cassio that the only way to be back on Othello’s good side was to get close to his love, and that is Desdemona. So while Othello’s suspicious are up, Cassio is being especially nice to Desdemona. Iago chose a very good time to attack Othello’s emotions. At a time when Cassio has wronged Othello, he tells Cassio to get close to Othello’s wife, the love of his life. For a lot of Othello’s rule, Iago has been like Othello’s advise giver. He has been like a best friend to Othello. Iago was not only Othello’s advise giver but to many persons of power. This puts him in a great position already to do his evil bidding. Othello plays right along with Iago’s plan. Othello believes everything that Iago says. In a way, he falls into Iago’s plan a little to well. For Iago, everything happens at exactly the right time. Othello listens to what Iago says because Iago has gained much trust from Othello. He has no reason not to believe what Iago was saying. He played a part in his own downfall because he falls for every lie that Iago throws at him. He needed to have a stronger mind for things like that. Othello needed to think harder about what was being said to him by Iago. At the time that Iago was telling him these lies, it all seemed to make sense.

Psychology and the Importance in Churches Essay

I believe psychology is important in churches today because when I look at the attitude and conduct of church members, it exhibits the function of one’s mind, social behavior and development. Specifically when dealing with the mechanics of reception. Religions and churches face different possible reactions from its members or visitors which are directly correlated to the human behavior of the mind. It is easy to see how the Muslims by their social behavior are so fanatical and often times all-consuming in their faith. Muslims are more inclined to say that their religion is an important part of their daily lives. It is said that nine out of ten Muslims said their faith was more important in their lives, while the figure was 85% for Hindus and 66% for Christians. We see that there are various levels of reaction; other religions could fall into the category of having strong and mild attachment, proving that the human mind is a key ingredient into how people react and consume religion. This not only plays a role in people with religious beliefs, it’s also displayed in non-believers of faith such as agnostics and atheist. This is so because religion will not have an impact on some individuals; they will be indifferent, having no particular interest or sympathy. While others may be observant, willing to learn but some will still be unmoved to come to faith or beliefs. These are just a few arguments as to why I feel psychology plays a pertinent role, because people that help make up all religions will have different reactions from their minds, thus leading to various behaviors and level of belief. Along with actions and reaction, the mind will also contemplate upon past experiences, this enables one to either come to faith or not at all, based on what someone had said or done to them. This is known as locking or unlocking the mind. In conclusion, Behaviors and reactions are a state of one’s mind based upon life experiences. Psychology and the human mind play an intricate role in the growth or stunt of a Religion or a Church.
