Roman Roads free essay sample

Compare/contrast Roman roads to modern roads The Romans created many useful objects that people use today. For example, they created arches, domes, pizza, and many other great things. The strong Roman road stuck out in my mind because we use roads everyday. The modern road wouldnt be strong and durable enough if the tough Roman road wasnt created. One of the secrets behind the Roman roads success is the materials used to form it. The bottom layer of the mighty Roman road, called the fossa, is made up of fine dirt. The middle layer, called the pavimentum, is crafted with gravel or sand. The second to top layer, known as the radus, is made with fine concrete. The top layer, called the summum dorsum, is made with flat stones and concrete. Our modern roads are made with crushed rock, known as arggregate, at the bottom. Then there is the base, which is a huge layer of concrete in the middle. We will write a custom essay sample on Roman Roads or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Lastly, there is the pavement, called the super pave, at the top. Both Roman roads and modern roads have had many uses. One usage of the roads is for transportation of people. Another usage is the transportation of food and supplies. Lastly, both the Roman road and the modern road have been used for parades. There are quite a few similarities between Roman roads and modern roads. One of the similarities is that both are made up of a mixture of rocks and concrete. Also, both last a long time and are only only fixed when needed. Likewise, both usually have a drainage system on the sides of the road. Lastly, both supported parades when they were used. There are also differences between the Roman road and the modern road. For instance, Roman roads are older than modern roads and last longer. Also, modern roads have covered drains, while Roman roads have coverless ditches. Furthermore, Roman roads have tightly fitting stones on the surface while modern roads are paved on the surface. Lastly, Romans used horse drawn carriages, oxen drawn carriages, or chariots for transportation, while in modern times we use cars and bicycles to get around. Roman roads have a major effect on my life. I use roads to go to school and other places usually everyday. If there were no such thing as Roman roads, transportation would be harder today. Without roads, it would take me longer to go to school and such. Food and other necessities would take longer to come. Even if we use planes, we wouldnt have a smooth runway for takeoff. That is why Roman roads have a major effect on my life. Roman roads are important to us because because they make transportation easier. Without Roman roads, we wouldnt have durable roads today. I think the Roman road was a great invention because it helped make transportation quicker and easier. Also, Roman roads made the movement of goods faster. Most inventions that transport objects and such need a smooth, strong road to be successful. For example, airplanes need smooth runways, cars need strong roads, and helicopters need a safe landing platform. That is why I think the Roman road is a great architectural achievement.

Symbolism In Master Harold . . And The Boys Essays - Free Essays

Symbolism In 'Master Harold' . . And The Boys Essays - Free Essays Symbolism In 'Master Harold' . . And The Boys Symbolism in 'Master Harold' . . and the Boys Ainsley Donovan 125055 English 110.6 Section 23 April 25, 1997 Athol Fugard's 'Master Harold' . . . and the Boys is about Hally, a white young man, and the damage done by apartheid and alcoholism. The play takes place on the southeast cost of South Africa, 1950, in Hally's parents' restaurant. This is where two black servants, Sam and Willie, work for the white family. Sam and Willie have been a part of Hally's upbringing and are close friends. Hally has educated Sam with the knowledge acquired from school textbooks, but Sam has been trying to teach Hally vital lessons necessary for a healthy lifestyle. With a racist environment and a boorish alcoholic as a father, Sam has been a positive role model for Hally. The question would be, could Sam's influence outweigh the negative environment, shaping the confused boy? There are symbols in the play that illustrate the stimuli contributing to the answer. In 'Master Harold' . . . and the Boys, one can examine the kite, dance, bench, and disease; these are the symbols of the conflicting forces competing for Hally's future. The kite is an object symbolic of transcendence. Even as a child, Hally had an ingrain sense of defeat, disappointment, and failure; that is why Sam made him the kite. He wanted the little boy to be proud of something, proud of himself. Sam gave to him the phenomena of flying, the ideology of climbing high above his shame. The kite triggered neurotic thoughts but exhilarated the despairing boy. This is it, I thought. Like everything else in my life, here comes another fiasco. Then you shouted Go, Hally! and I started to run. I don't know how to describe it, Sam. Ja! The miracle happened! I was running, waiting for it to crash to the ground, but instead suddenly there was something alive behind me at the end of the string, tugging at it as if it wanted to be free. I looked back . . . I still can't believe my eyes. It was flying. . . I was so proud of us. . . I would have been suicidal if anything had happened to it(Fugard, pp.1691-92). The kite conjured up ideas and feelings of believing in miracles, of being alive, and free. Sam left Hally up on the hill, with the a sense of pride, beside the bench. Hally wondered why Sam had left him alone that day. The two of them were up there for a long time; the only bench on the hill read whites only. The bench is the symbol of apartheid, division, hatred, and racism. It is apartheid that Hally hides behind as he uses Sam and Willie as his scapegoat. Hally is filled with so much rage over his father, he is torn between love and hate. When the conflict supernovas, Hally lashes out on his two black friends. He tries to pretend they are not friends by acting strictly like a boss. Carrying on with this little man routine, Hally asks Sam to call him Master Harold. Sam would only do this if they were no longer friends; Hally would be no different from his father. This is the case for, when he spits in Sam's face, Hally becomes Master Harold. Apartheid is victorious in the corruption of another white male as Hally takes his place on the bench of segregation. If you're not careful . . . Master Harold . . . you're going to be sitting up there by yourself for a long time to come, and there won't be a kite in the sky(Fugard, p.1709). Along with the kite and the bench, the dance is another symbol in 'Master Harold' . . . and the Boys. After one of the phone calls that trigger his explosions, Hally, once again, is calmed by the idealistic voice of Sam. They begin talking about the art of dancing and how it can be seen as a metaphor of life. The dance is a symbol of inner harmony, social peace, and a world without violence or aggression. This is an ideal world. Sam points out that none of us know the steps; there is no music playing, but it does not stop the whole world from continuing. Even though there are bumps that leave bruises, life keeps on existing. We should just learn to dance life like champions. Hally, who only has words and books without value, falls in love with this analogy. At least

Week 2 ILAB Research Paper Example | Topics and Well Written Essays - 250 words

Week 2 ILAB - Research Paper Example The sweetener is relatively safe in terms of both physical and chemical reactions. The sweetener reacts slowly with both cold and hot water. The sweetener is soluble in all liquids but its solubility depends on different temperature. However, it creates certain diseases such as diabetes mellitus and diabetes insipidus if consumed at high or low levels respectively. Different research studies show that sucrose is not associated with obesity, for example Bolton-Smith and Woodward found no relationship between bodyweight, and sugar intake in Australian adults aged between 25-64 years (Winsome Parnell, 2007). This data is in agreement with that of Gibson, who found no evidence that obese people in the United Kingdom were consuming a diet high in sucrose. A study carried out in New Zealand also showed that overweight adults did not have a high sugar intake than normal weight adults; obese children also gave the same results (Winsome Parnell,

Encryption and network security Essay Example for Free

Encryption and network security Essay Honeynets: Observing Hackers’ Tools, Tactics and Motives in a Controlled Environment Solutions to hacker attacks are usually fixes that are developed when damage has been done. Honeynets were solely developed to catch and monitor threats (i. e. a probe, scan or attack). They are designed to gather extensive data about the threats. These data are then interpreted and used for the development of new tools to prevent actual damages to computer systems. Talabis defines a honeynet as a network of high interaction honeypots that simulates a production network and configured such that all activity is monitored, recorded and in a degree, discretely regulated. Seen below is a diagram of a typical honeynet setup as given by Krasser, Grizzard, Owen and Levine. Figure 1 A typical honeynet setup Deployment of honeynets may vary as it is an architecture. The key element of any honeynet is the honeywall. This is the command and control gateway through which all activities come and go. This separates the actual systems from the honeypot systems wherein threats are directed to intentionally. Two more elements are essential in any honeynet. These are discussed below. Data Control Data control is necessary to lessen the risks posed by the captured threats without compromising the amount of data you are able to gather. To do this, connection counting and Network Intrusion Prevention System (NIPS) are used. These are both automated data control. Connection counting limits outbound activity wherein connections beyond the limit are blocked. NIPS blocks or disables known threats before it can attack outbound. The Honeynet Project Research Alliance has defined a set of requirements and standards for the deployment of Data Control. First is the use of both manual and automated data controls. Second, there must be at least two layers of data control to protect against failure. Third, in case of failures, no one should be able to connect to the honeynet. Fourth, the state of inbound and outbound connections must be logged. Fifth, remote administration of honeynets should be possible. Sixth, it should be very difficult for hackers to detect data control. And finally, automatic alerts should be raised when a honeynet is compromised. Data Capture The Honeynet Project identifies three critical layers of Data Capture. These are firewall logs, network traffic and system activity. The data collection capabilities of the honeynet should be able to capture all activities from all three layers. This will allow for the production of a more useful analysis report. Firewall logs are created by NIPS. The Snort process logs network traffic. Snort is a tool used to capture packets of inbound and outbound honeynet traffic. The third is capturing keystrokes and encryption. Sebek is a tool used to bypass encrypted packets. Collected data is hiddenly transmitted by Sebek to the honeywall without the hacker being able to sniff these packets. Risks As with any tool, honeynets are also threatened by risks affecting its usage and effectiveness. These include the risk of a hacker using the honeynet to attack a non-honeynet system; the risk of detection wherein the honeynet is identified by the hacker and false data is then sent to the honeynet producing misleading reports; and the risk of violation wherein a hacker introduces illegal activity into your honeynet without your knowledge. Alerting As mentioned in the requirements and standards set for data control, alerts should be in place once an attack is done to your honeynet. Otherwise, the honeynet is useless. An administrator can monitor the honeynet 24/7 or you can have automated alerts. Swatch is a tool that can be used for this. Log files are monitored for patterns and when found, an alert is issued via email or phone calls. Commands and programs can also be triggered to run. Honeynet Tools Several honeynet tools are available to the public for free so they can setup their own honeynet for research purposes. These tools are used in the different elements of a honeynet. Discussed below are just three of them. Honeynet Security Console This is a tool used to view events on the honeynet. These events may be from SNORTÂ ®, TCPDump, Firewall, Syslog and Sebek logs. Given these events, you will be able to come up with an analysis report by correlating the events that you have captured from each of the data types. The tool’s website lists its key features as follows: quick and easy setup, a user-friendly GUI for viewing event logs, the use of powerful, interactive graphs with drilldown capabilities, the use of simple search/correlation capabilities, integrated IP tools, TCPDump payload and session decoder, and a built in passive OS fingerprinting and geographical location capabilities. Honeywall CDRom Roo This is the recommended tool for use by the Honeynet Project. This is a bootable CDRom containing all of the tools and functionality necessary to quickly create, easily maintain, and effectively analyze a third generation honeynet. Much like the Honeynet Security Console, this tool capitalizes on its data analysis capability which is the primary purpose of why honeynets are deployed – to be able to analyze hacker activity data. GUI is used to maintain the honeywall and to track and analyze honeypot activities. It displays an overview of all inbound and outbound traffic. Network connections in pcap format can be extracted. Ethereal, another tool, can then be used with the extracted data for a more in-depth analysis. Sebek data can also be analyzed by this tool. Walleye, another tool, is used for drawing visual graphs of processes. Although this tool may be useful already, several improvements will still have to be introduced to increase its effectiveness. Walleye currently supports only one honeynet. Multiple honeynets can be deployed but remote administration of these distributed systems still needs to be worked on. Sebek This is a tool used for data capture within the kernel. This is done by intercepting the read() system call. This hiddenly captures encrypted packets from inbound and outbound activities by hackers on the honeypot. Basically, Sebek will tell us when the hacker attacked the honeypot, how he attacked it and why by logging his activities. It consists of two components. First, a client that runs on the honeypot. Its purpose is to capture keystrokes, file uploads and passwords. After capturing, it then sends the data to the server, the second component. The server normally runs on the honeywall where all captured data from the honeypot are stored. Found below is the Sebek architecture. Figure 2 Sebek Architecture A web interface is also available to be able to analyze data contained in the Sebek database. Three features are available: the keystroke summary view; the search view; and the table view which provides a summary of all activities including non-keystroke activities.

Law School Admissions Essay - The Spirit Lives -- Sample Law School Ad

"Hasta la victoria siempre." (Che Guevara) I want to study law so I can help people with problems in the workplace.   I am unhappy with the decrease in real wages, the huge increase in temporary and part-time employment that includes few or no fringe-benefits, and the continued existence of unsafe work places.   I believe that technological advances are going to continue to put people out of work, perhaps on a massive scale, in the next twenty to fifty years, and that government, business, and workers will have a new opportunity to share the gains in productivity that are to come.   I believe that people have the right to work at a job that allows them to afford to raise a family, live in a comfortable, safe home, and work in a safe environment.   I want to devote my work to improving workers' pay levels, assuring them access to health care, paid vacation time, fair treatment by their employers, and physical safety in the work place.   Increasing the number of safe, well-paid, secure jobs will go a long way towards helping alleviate many of the social ills that are associated with poverty.   Ã‚  Ã‚   I was involved with labor issues at my job at the San Francisco International Youth Hostel, where I worked from 1992 to 1996.   I helped organize a group of workers there to discuss our work place and to smooth out scheduling conflicts between management and our group of workers.   In September 1995, part-time staff's holiday pay was taken away without any discussion at all, and I called the Executive Director of the Company the (The Golden Gate Council) and persuaded her to re-institute it.   I was regularly consulted for my opinion on various wage, hour and working-condition matters.   Ã‚  Ã‚   I have seen how working people organize them... ...ing as a community organizer for a volunteer service-exchange program that benefits seniors and the disabled.   the work I am doing reinforces the goals I have of helping solve problems in the workplace.   At my job here in West and South Berkeley, I have again seen the poverty that a dearth of good jobs breeds in a community.   I want to help raise my community's living standards through a more equitable sharing of the resources we transform in our workplaces.   Ã‚  Ã‚   The last thing I can say about myself is that I am interested in almost everything and hope to learn much more about solutions to social problems, science, questions of spirituality and religion, history, visual arts, music, literature, and the list could go on for a while form there.   The curiosity and interest in knowing about the world is an asset that I will take into whatever endeavor I choose.

Division of the Department of Education Essay

The Cebu City Schools Division of the Department of Education (DepEd) is reminding public school canteens about the policy prohibiting the selling of junk food and softdrinks. According to the Education Program Supervisor Delia Kiamco, they are regularly monitoring public school canteens to ensure that they only sell nutritious food. Business and sanitary permits and other licenses are annually checked by DepEd to assure that the food sold in the canteen are clean and safe. Kiamco said that those who are managing canteens should always bear in mind that service and not profit is the main consideration in operating a school canteen. As provided for under DepEd Order 17, only nutrient-rich and fortified food shall be made available in school canteens. Processed fortified food should bear the ‘Sangkap Pinoy’ seal. Among beverages, only milk, vegetable and fruit shakes and juices are allowed. Kiamco said that in order to curb the malnutrition problem among school children, selling of soft drinks and other carbonated drinks, sugar-based synthetic or artificially flavored juices and junk food are prohibited since these are detrimental to children’s health. DepEd also prohibits the use of mono sodium glutamate or vetsin in food. Only iodized salt should be used to help eliminate the iodine deficiency disorder among school children. School canteen operators are required to post their menu indicating nutritional value on a bulletin board within the school canteen premises. Label dilemma However, Kiamco said that because almost all junk food brands in the market have the â€Å"Sangkap Pinoy† and Fortified seal some canteens justify their sale. â€Å"Sometimes, canteen operators are after money making. We are strongly implementing the food service teachers from selling softdrinks and junk food,† Kiamco said. Kiamco said that they will hold another meeting to decide what action to take on food products with Sangkap Pinoy and Fortified labels. She is asking the public to report to DepEd if there are any public school canteens that still sell prohibited food and drinks. DedEd is also having problems with those selling junk food outside school campuses. â€Å"We cannot do anything against these vendors outside the schools except to remind students not to patronize them,† said Kiamco. /Christine Emily L.
