Physics : Atomic Absorption ( Aa ) Spectroscopy

- Theory: Atomic Absorption (AA) Spectroscopy is a quantitative analysis technique that uses the absorption of light through a flame and gaseous chemicals. AA Spectroscopy can be used for a multitude of purposes, most notably finding the concentration of one or a few elements in a compound. AA Spectroscopy can work in two different ways using an open flame and gaseous chemicals or a graphite furnace. Flame AA Spectroscopy works by taking a compound or element and disassociating it into an aqueous solution....   [tags: Spectroscopy, Chemistry, Absorption spectroscopy]

The Israeli Ministry Of Absorption

- Similar to immigrants who journeyed to the United States with an “American Dream,” Russians arrived in Israel with high expectations and believing promises that were made to them. Unfortunately, some promises were “deceitful,” such as portraying the city of Ariel in the West Bank “as a university town in the center” (Glozman, 2013). While immigrants were facing immediate instabilities, the burdens of their situation accentuated Israel’s larger economic vulnerability. According to the Middle East Research and Information Project: The Israeli Ministry of Absorption developed a “direct method” whereby immigrants have free choice on where to settle; they are not directed to an absorption cente...   [tags: Israel, Judaism, Ethiopia, Beta Israel]

Luminal precipitate formation requires high concentrations of divalent ions and a chemically favorable high pH. The high divalent ion content required for precipitate formation is supplied by the high calcium content of imbibed seawater, that reaches the intestine in a concentration range that varies between 3-15 mM depending on the species (Fuentes et al., 2006; Genz et al., 2011; Wilson et al., 2002)....   [tags: water, fluid, absorption, intestine]

- Hydrocephalus is a condition characterized by cerebrospinal fluid (CSF) accumulating in excess in the brain. Ventricles, which are spaces in the brain, begin growing abnormally large because of the excess fluid. The widening ventricles can cause harmful pressure on brain tissues. Normally, CSF flows freely through the ventricles of the brain, coats the brain and spinal cord, and is reabsorbed by bloodstream. This fluid is constantly produced, so equilibrium between production and absorption is essential for the body....   [tags: obstruction, passageways]

Spectrophotometry measures the amount of any chemical substance which is absorbed or transmitted. A spectrophotometer is an apparatus used to measure the intensity of light after passing through a solution. Visible spectrophotometers use light over the ultra violet range 185-400nm and visible range of 400-700nm of electromagnetic radiation. When using visible spectrophotometry to determine absorption or transmission you need to observe the colour of the solution....   [tags: Chemistry, Concentration]

We can view a large range of color from a small selection of wavelengths along the electromagnetic spectrum, 400nm-700nm. Our understanding of this perception of color comes from two major theories Tri-chromatic theory of color vision and opponent-process theory. Both theories have their merits and one actually grew out of the other. The first theory that was proposed was the tri-chromatic theory. The tri-chromatic theory of color vision states that our color vision is dependent on the activity of our three color receptors....   [tags: Color, Color blindness, Color vision]

How the Human Body Obtains Cholesterol

- According to the scientific report from Gunness and Gidley (2010), the human body obtains cholesterol from two sources. The major source is liver. Liver synthesizes about 700-900 mg cholesterol per day. Another source is diet, which account for up to 300-500 mg/d. The major route cholesterol eliminates from human body is to convert to bile salts (BS) and excrete from the gastrointestinal tract (Gunness & Gidley, 2010). Bile salts (BS) are synthesized from cholesterol in the liver. Hydroxyl (OH) groups are inserted at several points of cholesterol, and then the second ring of cholesterol loses its double-bond....   [tags: liver, diet, metabolism]

- Photosynthetic organisms have the ability to convert solar energy into electrochemical energy. This creates a dynamic relationship between the organisms and the light that they absorb. Although light is required to drive photosynthesis, the photosynthetic machinery can only tolerate so much of it. Excess light may lead to the generation of reactive oxygen intermediates resulting in oxidative damage to the photosynthetic apparatus (Niyogi, 1999). Therefore it is necessary for organisms such as the green algae Chlamydomonas reinhardtii to employ photoprotective mechanisms in order to maintain photosynthetic efficiency and reduce stress caused by excess light....   [tags: Photosynthesis, Oxygen, Redox, Chlorophyll]
