...Introduction and Abstract Copyright(c), 1984, Fred Cohen - All Rights Reserved This paper defines a major computer security problem called a virus. The virus is interesting because of its ability to attach itself to other programs and cause them to become viruses as well. There are two spellings for the plural of virus; 'virusses', and 'viruses'. We use the one found in Webster's 3rd International Unabridged Dictionary Given the wide spread use of sharing in current computer systems, the threat of a virus carrying a Trojan horse [Anderson72] [Linde75] is significant. Although a considerable amount of work has been done in implementing policies to protect from the illicit dissemination of information [Bell73] [Denning82], and many systems have been implemented to provide protection from this sort of attack [McCauley79] [Popek79] [Gold79] [Landwehr83], little work has been done in the area of keeping information entering an area from causing damage [Lampson73] [Biba77]. There are many types of information paths possible in systems, some legitimate and authorized, and others that may be covert [Lampson73], the most commonly ignored one being through the user. We will ignore covert information paths throughout this paper. The general facilities exist for providing provably correct protection schemes [Feiertag79], but they depend on a security policy that is effective against the types of attacks being carried out. Even some quite simple protection systems cannot be proven 'safe' [Harrison76]...

...These wars caused many laborers to stop their way of living and move into the cities. Thus diseases and viruses, such as the smallpox, infected the cities causing death to many.1With emperors coming and going, one strict emperor named Diocletian, ruled. In his reign, he was able to save the economy and handle the army’s needs.1His most important contribution was when he decided to separate administrations. He instituted the Tetrarchy, which separated the empire into the Western and Eastern Roman Empire, appointing an emperor and a junior emperor to each empire.1Diocletian became a branch that led to a declining Western Empire and a flourishing Eastern...

...their temper and values. As a result, the both sides will fight against each other. Gamble is also present in the game, the highest bet is 5,000 pesos and the lowest is 300 pesos. Again, money for them is not that important anymore. Many players says that “Dota is the best past time ever,” so it’s Ok for them to waste their money. Due to playing, eating is irrelevant; the satisfaction they get form playing is the same as the satisfaction they get from eating. As a result, the body’s immune systems are getting weaker and now expose the different viruses and diseases. All in all, Dota really affects the life style of the youth who are in to this game, although it has one good benefit, but it corrupts the mind and the way the youth think. It also weakened the body system, money and moral values were not given importance because of this game. There are many students and even some young professional are addicted to Defense of the Ancients or Dota. This is a kind of computer games that can be played by many players and is one of the most popular games to young students. Many students get addicted to this game and they even long hours inside the computer shop just playing this kind of game. There are studies that getting addicted in playing computer games affects their studies and this is the cause why they are lying to their parents that they need extra money for their school project but the truth is they are just using the money to rent a computer where they can play Dota with their...

...Of all the marvelous feats in Roman architecture, few rival the societal contributions of the Cloaca Maxima and the system of Aqueducts. Sanitation in early Roman society was far from adequate. With the lack of any significant drainage system, human and animal waste alike covered the streets and flooding among low lying areas of the city was substantial . The issue of water was also prevalent. The city suffered from a lack of fresh water flow that not only led to an extreme shortage of drinkable water, but also to a stagnation of the city’s waste . Rome was in desperate need of a system that both provided water free from pollution for consumption and also supplied a constant flow to the various public baths, toilets, fountains, and private households. The Great Greek historian Dionysius of Halicarnassus stated in his collection “Roman Antiquities” that “The extraordinary greatness of the Roman Empire manifests itself above all in three things: the aqueducts, the paved roads, and the construction of the drains .” Dionysius’ statement certainly rang true. The commissioning of the roman aqueducts as well as the construction and expansion of the Cloaca Maxima were vital to the improved sanitation in Rome. To understand how important these two architectural feats were to the Roman people, it is necessary to first understand the state of Roman sanitation before major expansions to the aqueducts and sewage system. Most Romans relied heavily on limited local sources like springs and...

...Assignment 2: Goddess Essay Hera Adam Smith 24th April 2012 Hera is undoubtedly one of the most complex goddesses portrayed throughout history. Unlike many other goddesses who have kept relatively stable images, Hera has been tossed out and about being perceived on entirely different ends of the spectrum as both the Great Mother Goddess and the nagging and jealous wife of Zeus. She is the perfect example of a matriarchal deity that was taken over and transformed by patriarchal culture. It was in “Old” Ancient Greece that Hera was the primary divinity of a matriarchal culture, until the “New” Ancient Greece was founded by the Indo-European Hellenes from the north. It was the Mediterranean pre-Hellenic Greeks that worshiped Hera, and their culture was based around women (Morgan, 2006). Hera was portrayed in the three stages that women experience: the maiden (youth without children or responsibility), the mother (women with children and families in the prime of their lives), and the crone (past mothers who live for themselves once again). There was actually a competitive festival that happened every four years (like a sort of female Olympics) in which women of all ages were divided into three age groups (representing the three stages of Hera) and participated in 160-yard races, bare-breasted and with their hair unbound. There were three winners (one for each age/life stage category) and each winner had the honour of placing a statuette of herself in Hera’s shrine, received...

...DBRAE200D Professor Daily 28 October 2012 Position Essay: The Necessity for the Explanations of Weather in Ancient Greece The complex, but plausible circumstances surrounding the explanations for different forms of weather in ancient Greece were necessary due to the lack of technological and intellectual advancements it took to really explain the origins of wind, thunderstorms, and rain. “The economy of the ancient Mediterranean world was agriculturally-based. Given the importance of weather to agriculture, it should not be surprising that there was a good deal of interest in the explanation and prediction of weather in the ancient world” (Taub). The mortals of ancient Greece were “normal” people. They worked for a living, served the gods and feared Zeus’ wrath. More revolutionary explanations for the weather in their world would not come around for hundreds of years, leaving a haze of uncertainty and a flurry of stories. The ancient Greeks had many explanations for and references to natural occurrences such as rain, wind, and thunderstorms. The thoughtful myths and the reasoning behind them made these curious occurrences suddenly logical and rational. It was through the descriptions of these events that the mortals of Greece realized that the actions of the gods were out of their control. Taking into account the simplistic lifestyle that Greek mortals led in a society sustained by growing crops year-round, they needed to know-or think they knew why their crops would die...

...Ancient Egypt Love Poems Ancient Egypt literature and poetry foundation and growth were religious basses and beliefs. In a short amount of time, poetry evolved to deal with people ordinary lives and had a great place among Ancient Egyptian civilization. They wrote religious hymns, plays, dramatic poetry, songs, and in particular love poetry. Ancient Egyptians started and utilized strong literature in order to efficiently communicate their feeling that it affected other cultures, yet these master pieces lack names and titles. These master pieces are originally written inside tomb walls, papyrus and limestone which celebrates the pleasures of food, music, dance, and love. Ancient Egypt Love Poems are significant in our literature because they are one of the first recordings of human literary works and sure enough the earliest example of love poetry. It took them a long time to create these magnificent pieces of literature in writing, but before that oral poetry was part of their tradition; composition of Hymns, stories, and prayers that were passed down from a generation to another orally. The reason was that only a few could read and write in a city and they were more likely royals and merchandisers. Egyptian invented hieroglyphic writing to help their trade system for recording their merchants; later on, they used this writing in tombs in order to compose biographies, narrative poems, and songs. Soon after, Egyptian came up with a new system of writing, hieratic script, which...

...UYO AKWA IBOM STATE, NIGERIA. FEBRUARY, 2012 1. INTRODUCTION All human societies have medical beliefs that provide explanations for birth, death, and disease. Throughout history, illness has been attributed to witchcraft, demons, astral influence, or the will of the gods. These ideas still retain some power, with faith healing and shrines still used in some places, although the rise of scientific medicine over the past millennium has altered or replaced mysticism in most cases. The ancient Egyptians had a system of medicine that was very advanced for its time and influenced later medical traditions. The Egyptians and Babylonians both introduced the concepts of diagnosis, prognosis, and medical examination. The Hippocratic Oath, still taken by doctors today, was written in Greece in the 5th century BCE, Horstmanshoff et al (2004:7). In the medieval era, surgical practices inherited from the ancient masters were improved and then systematized in Rogerius's The Practice of Surgery. During the Renaissance, understanding of anatomy improved, and the invention of the microscope would later lead to the germ theory of disease. These advancements, along with developments in chemistry, genetics, and lab technology (such as the x-ray) led to modern medicine, O'Leary (1939:65). 2. PREHISTORIC MEDICINE Although there is no record to establish when plants were first used for medicinal purposes (herbalism), the use of plants as healing...

...of Khufu and some say Djedefre, also Khufu’s son was the immediate successor and Khafre followed his rule. Either way Khafre is known to have ruled during the 4th Dynasty of the Old Kingdom. During his rule he was married to two queens, Khamerenebty I and Meresankh. He had a son with Khamerenebty who was named Menkaure and became king after Khafre’s death. When Khafre became king seems to be lost in history. Sources I have come across believe his rule to roughly be between 2558 BC and 2532 BC. Our book however, (Art History Vol. 1) states his rule to be from 2520-2494 BCE. What I get from this is that little evidence is available for a reliable time of rule. Khafre’s pyramid which will be the main focus of my paper is one of the Ancient Egyptian Pyramids of Giza located in the outskirts of Cairo, Egypt. Khafre’s pyramid lays roughly a few hundred meters to the southwest of his father Khufu and Menkaure’s pyramid lays a few hundred meters further southwest of his father. (Pyramids by Joyce Filer) It only seems natural to first discuss the creation of the pyramid temple of Khafre. To build such a monumental structure thousands of workers would be needed including stone cutters, surveyors, carpenters, mortar makers, and general laborers. These worker would work year round and would stay on site whether at the build site or in the quarries. The stones they used at the bottom of the pyramid are very large and decrease in size to twenty inches thick at the top. Larger...

...town stood. The town government was led by a lord mayor and a council, whom usually were among the wealthiest of the tradesmen and craftsmen. A town was usually surrounded by big stone walls. People lived in tall, narrow wooden houses, usually with more than one floor. The ground floor normally was used as the owner’s shop or area to practice his profession. The other floors were the living spaces of the household, and also the place where they kept their animals. Roads in the towns were narrow and long. Before the 13th century, streets were the responsibility of each household. Later on when the council started taking more responsibility, new roads were often built over the previous ones, without bothering to clean them. In London ancient Roman ruins are found at 20 feet below today’s street level. Even though people were supposed to be responsible for the part of the street in front of their house, they never showed much concern and never tried to keep it clean. The only exceptions were during an outbreak of the plague or a royal visit. This wasn’t the only problem for sanitation in the medieval cities. Main drains ran along the side of the streets and people threw dirty water out in their general direction. Stables opened into the streets and livestock like pigs were left to roam. Many people had pigs because they were...

...Sculptures fulfilled a publicity role, as they had no newspapers or photographs these sculptures were a way to communicate to the public. Realism, hair gains volume, beard appears, Chiaroscuro effects First, that sculpture in this text functions as a kind of mapping device, as a means of constructing or imagining a sacred territory. Second, that the resulting “sacred map” is actually more about locating self than the sacred, about negotiating identity within a particular place and time, and in the face of a variety of socio-politico-cultural forces, in this instance, Flavian Rome. (Ehrenkrook 2008) Among the social institutions of ancient Rome, public baths were unique for their inclusive rather than exclusive policy and their vast appeal to the masses regardless of sex, color, creed, or wealth. Roman baths . What is more interesting, although we have considerable evidence for social segregation in many other institutions of public entertainment, such as the theater, the amphitheater, the stadium and the circus where sits or blocks of seats were formally and rigidly reserved for certain classes or groups, the same groups in mentioned in their benefaction charters appear to have mixed in public baths without restrictions. (Yegul 2010) when fine polished stones are carved, the strong light and reflections conceal the carving. The carving could best be seen by turning the carved part against a strong light."
