CHAPTER 2. THE INTERNET AND WORLD WIDE WEB
-Advanced Research Projects Agency (ARPA)…an agency of the U.S. Department of Defense. ARPA’s goal was to build a network that (1) would allow scientists at different locations to share information and work together on military and scientific projects and
(2) could function even if part of the network were disabled or destroyed by a disaster such as a nuclear attack.
Rheumatoid arthritis is not curable. Medications will be recommended to relieve pain, reduce inflammation, slow the progression of RA, and save joints and tissues from permanent damage (Rheumatoid Arthritis, 2017). The most common medications are nonsteroidal anti-inflammatory drugs (NSAID) and disease-modifying antirheumatic drugs (DMARD), e.t.c. When having RA, it is important to exercise regularly, apply heat or cold to affected areas, relax, and eat healthy. Physical therapy is usually part of treatment for RA. The goal is to stimulate the bones, muscles, and joints to give them strength and flexibility (Physical Therapy for RA, n.d.). Foods that have lots of omega-3 (fish, chia seeds, flax seeds, and walnuts), high antioxidants like vitamin A, E, and C (berries, dark chocolate, spinach, kidney beans, pecans, and artichokes), and lots of fiber can help reduce inflammation (Foods that fight RA inflammation,
There are some traditional medicines that are used to help with Rheumatoid Arthritis such as a mixture of ufudu, sengaparele, and ishaba bark are boiled and then strained. The patient should drink it four times daiy to take away pain. There have been many tests done and it has been proven that in most pateints borage seed oil helps to relieve pain and swelling of joints. Blackcurrent seed oil also improves the tenderness of joints in patients with Rheumatoid Arthritis.
Across the world there are countless religions, new and old, each having their own unique traditions and laws that believers abide by. As defined by World History, Sharia, the Arabic word meaning “the path” or “the way”, alludes to traditional Islamic law. (Ellis, Esler, and Beers, 255) Sharia originates within the Koran, the holy book of Islam, which Muslims consider the unaltered word of God. Along with the Koran, Sharia is derived from the teachings and examples set by the Islamic prophet, Muhammad, who Muslims view as the perfect man of faith. Muslims believe that God revealed his true conviction to Muhammad, who in turn was to spread the commands of God through the Koran. Between Muhammad’s death in the seventh century and leading up to the tenth century, many Islamic scholars worked to understand Sharia in its entirety, and apply it to the rapidly expanding Muslim Empire of the time (Dunn, 57). Sharia played a key role in uniting the Islamic Empire by serving as the precedent which dictated laws concerning both private and public behavior.
Furthermore, Sharia is not only an arrangement of laws but also the proper way of life, and guidance of Allah. For example, in Sharia there are differences between the various schools of law as to the level of what a woman may wear and reveal in public. (Friedland) The Qur 'an is the key source of the Sharia, both the Qur 'an and Hadith push the thought of modesty in the way women of the Islamic faith dress when in public. In essence Sharia is simply endeavors by Muslims to make an arrangement of common society and administration with equity and
“Saussure defined a sign as being composed of a signifier and a signified. The sign is the whole that results from association of the signifier with the signified. The relationship between the signified and signifier is signification. The signifier is now commonly interpreted as the material or physical form of the sign, it is something which can be seen, heard, touched, smelt or tasted. Both the signifier and the signified were purely psychological.” (Saussure,
Today, the swastika is typically identified with racism, hate, violence, death, and antisemitism due to the Nazis, however, its history shows that it was primitively a symbol for many other things, including life, the sun, power, good luck, and well-being. The word swastika comes from the Sanskrit svastika, which means “good fortune” or “well-being”. The swastika has been around for thousands of years, and some even say it is the oldest known symbol. It is thought to have first been used in Neolithic Eurasia, perchance depicting the movement of the sun through the sky. The symbol became sacred to the religions of Hinduism, Buddhism, and Jainism, and is a common sight to see in places like India and Indonesia.
A network can be based on either a peer-to-peer level or server-based, also referred to as domain-based. To distinguish the difference, a peer-to-peer network, also known as a workgroup, is a network in which a group of computers are connected together to share resources, such as files, applications, or peripherals. The computers in a peer-to-peer network are peers to one another, meaning no single computer has control over one another. There is also no central location for users to access resources, which means that each individual computer must share their files in order for other computers to have access (Muller, 2003, p.411). “In a peer-to-peer environment, access rights are governed by setting sharing permissions on individual machines.” (Cope, 2002) On the other hand, in a domain-based network, the computers connected together are either servers or clients. All of the other computers connected to the network are called client computers. The server is a dedicated machine that acts as a central location for users to share and access resources. The server controls the level of authority each user has to the shared resources. When logging on to the network, users on client machines are authenticated by the server, based on a user name and password (Lowe, 2004, p.13).
The problem of Rheumatoid arthritis is it causes disabling pain and is difficult to postpone the rate of which it develops. There are a number of ways the pain aspect can be reduced, and processes are available to avoid pain and prevent inflammation. The most common way to prevent this aspect is the use of painkillers such as codeine and paracetamol, non-steroidal anti-inflammatory drugs such as ibuprofen and naproxen, and corticosteroids drugs are usually used (4).
Rheumatoid arthritis, also commonly known as RA, is one of the most severe forms of arthritis an individual can have. About 1.3 million people in the United States suffer from this autoimmune disease that attacks one’s joints. The immune system will mistakenly attack normal cells within the body which can lead to inflammation in certain areas. RA is a chronic long term disease that cause edema, stiffness, pain and limited function of many joints. Many patient who suffer from rheumatoid arthritis state that their symptoms become worse in the morning or very late in the evening. RA may be hard to detect in many patients because of its subtle symptoms. Because many diseases behave like RA, it is hard to tell if achy joints and stiffness is a reliable symptom for this disease. Weakness, low grade fevers, loss of appetite are some of the first symptoms patients’ experience. Some other major signs and symptoms to look for are dryness of the eyes, mouth, nose and throat, stiff, locked joints particularly in the knees and elbows, and numbness or tingling in the hands. Although RA is a progressive disease that cannot be cured it is best that patients begin their treatment during the early stages; otherwise it can lead to permanent damage of the bones, joints, and cartilage. There are many treatment forms that are used in treating this disease. Disease modifying antirhumatic drugs such as Methotrexate and anti-inflammatories such as Mobic, are two classes of drugs that are highly effective for treating rheumatoid arthritis.
Software - the programs or language that controls the functioning of the hardware. Table of contents - a section on a CD that lists the locations of files to help a computer locate data.
A desktop computer consists of a computer system unit, a keyboard, a mouse, and a monitor. These are also input devices which are the devices used to input data in the computer or used to provide data and control signals to an information processing system. The computer system unit is the enclosure for all the other main interior components of a computer. The primary function of the computer system unit is to hold all the other components together and protect the sensitive electronic parts from the outside elements.
Sharia’s history can be dated back to 570 CE, in Mecca, the birthplace of Muhammad. Muhammad is Islam’s prophet, who unified Arabia into one religious state, by claiming to spread the revelations and word of God. The word of God was then created into the Quran, Islam’s most holy book; Muhammad’s sayings were put into the Hiddath, and his way of life and daily practices, were put into the Sunnah, also both holy Islamic scriptures. These holy books were created after Muhammad’s death, when the tribes of Arabia began to come together underneath one religion, and that was the beginning of Islam, and the birth of Sharia. The Sharia is taken from the Quran, the Sunna, and the Hadith, which are all religious texts.
System units are commonly mistaken as the Central Processing unit (CPU). System units sometimes called “computer chassis”, “base units” or “Tower cases” however are simply the housing for the integral parts of a computer. System units usual house all components of a computer excluding the monitor, Keyboard and mouse. System Units are a very simple component of the computer because they do none of the actual computing. They are usually just a square or rectangular prism made of some type of plastic or metal that hold all of the vital parts of a computer in a secure manner. Other than that there is not much to be said about the system unit.
According to Parsons and Oja (2014), they state that a “microprocessor is an integrated circuit designed to process instructions” (p 67).
Input is really important for the computer. Through this device, users are allows to enter data or instructions into a computer. It changed something on the screen through the response. There are many kinds of input device for users to select depending on their application to get the result they want. There are many input technologies, for example, keyboard, pointing device, trackball, touch screen, touchpads and audio input. These devices can help users to connect with computer system directly.
