Blood Cells Leukocytes (WBC’s) Leukocytes also known as white blood cells (WBCs) are cells which play a defensive roll in the body against injury and infection. They migrate towards tissues where they are needed and become functional performing various activities. WBCs can be divided into 2 groups: Polymorphonuclear granulocytes and mononuclear agranulocytes. Both types are spherical while suspended in blood plasma but when they invade tissues after leaving the blood vessels they become amoeboid

"A carbon fiber is a long‚ thin strand of material about 0.005-0.010 mm in diameter and composed mostly of carbon atoms. The carbon atoms are bonded together in microscopic crystals that are more or less aligned parallel to the long axis of the fiber. The crystal alignment makes the fiber incredibly strong for its size. Several thousand carbon fibers are twisted together to form a yarn‚ which may be used by itself or woven into a fabric. The yarn or fabric is combined with epoxy and wound or molded

Carbon-14 Dating: An Invaluable Yardstick in the Chronology of Humans Archaeologists utilize several methods to analyze data from the past. One scientific tool helps to analyze the radioactive decay of chemical elements found in plant and animal remains‚ pottery‚ and even rocks. Radiocarbon dating‚ also known as carbon-14 dating‚ has developed into one of the most important radioisotope dating methods archaeologists employ. This scientific tool‚ first developed by Willard F. Libby in the late

Carbon steel is steel in which the main interstitial alloying constituent is carbon in the range of 0.12–2.0%. The American Iron and Steel Institute(AISI) defines carbon steel as the following: "Steel is considered to be carbon steel when no minimum content is specified or required for chromium‚cobalt‚ molybdenum‚ nickel‚ niobium‚ titanium‚ tungsten‚ vanadium or zirconium‚ or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 0

government announced a framework to implement a Carbon Tax from July 1‚ 2012 has triggered an intense controversy among the Australian citizens. The term “Carbon tax” refers to an environmental tax that polluters will pay per ton of carbon they release into the atmosphere. This essay will argue that carbon taxes should not be introduced in Australia due to inefficacy‚ financial burdens and better actions to protect environment. First of all‚ implementing carbon taxes would not do anything to solve the

percentage of children within each blood lead level category‚ out of all children screened 9 to 47 months of age. The blood lead levels are organized into four categories: 0-4 µg/dL‚ 5-9 µg/dL‚ 10-24 µg/dL‚ and ≥25 µg/dL. For each category‚ the number (N) and percentage (%) of screened children whose highest blood lead specimen fell within the category is shown. Blood lead levels in the 10-24 µg/dL category are considered elevated and blood lead levels ≥25 µg/dL signify lead poisoning. Also‚ the CDC uses

life have increased the risk that information technology will be used unethically. At the centre of the government’s policy on climate change is pricing carbon. Many commenters and politicians have referred to this as a “carbon tax”. The idea is that polluters will pay per tonne of carbon they release into the atmosphere. This cost will initially be set at $23‚ and increase gradually until 2015. This is widely thought of as the most effective and least costly mechanism to reduce carbon output
