Absorption

over 80 women over the course of the research, giving them the jobs of analyzing spectral photographs for absorption lines in order to be classified. Williamina Fleming, former housekeeper of Pickering and the woman whom Pickering put in charge of the other workers, classified the stellar objects by their hydrogen lines. In the spectra of the various objects they were observing, the absorption lines of hydrogen were very strong in some objects and very weak in others, which was indicative of…

Discovered as a deficiency in the early 60’s, the chemical element zinc serves multiple roles in the body. Zinc travels through the body by protein which assists other proteins with metabolism. Moreover, zinc play a role in growth, development, behavior, and learning. In addition, zinc aids hormones such as thyroid and insulin. Zinc deficiency remain common in developing countries while less common in the United States…

The absorption of unknown # 2 was a lot higher than that of the 0.4 molar standard solution, which was also an indication that the concentration of unknown #2 was much higher than that of the 0.4 standard solution. Since the absorption is directly proportional to the concentration of the solution, we decided to dilute the mixture in a 1:1 ratio with distilled water. The…

deficient water. Thus, corns were not substrate for photosynthesis rate and stress. Corns produced less carbohydrates and starch that affect to yield. Root phenotype is long and short .long root is deep in soil for absorption of underground water. Short root is spread wide root at absorption of top soil for water and nutrients. When corns were got a lot of water or flood. Sometimes root of corns were not oxygen. Corn is low photosynthesis rate. Light Corns are low photosynthesis rate at low…

Lactate is co transported with protons. That’s why the lactate transport is affected by the protons gradient between blood and brain: when pH decreases, lactate absorption increases. 21 Degree in Physiotherapy. Biochemistry. With an important level of lactate and a prosperous protons gradient, we can see a considerable increase of lactate absorption by the brain. During a moderate exercise, the rate of lactate in arterial blood is superior to…

identify the unknown materials. In infrared spectroscopy the infrared radiations are passed through a sample. A portion of the radiation is absorbed by the sample and the remaining is passed through it. The resultant spectrum represents the molecular absorption and transmissions, creating a molecular finger print of the sample (Shurvell 2002). The advantages of infrared spectroscopy over other spectroscopic techniques include wide applicability, no destructiveness, measurement under…

A vegetarian diet is one lacking red meat, poultry and seafood. Whether or not vegetarianism is good for one’s health tends to be a controversial topic, as meat contains more essential nutrients than vegetables. Meat provides a higher-quality source of protein than vegetables because meat is packed with amino acids that vegetables do not supply. The type of iron in meat also absorbs better than vegetables which contributes to low iron levels in vegetarians. Due to these facts many believe that…

Abstract The purpose of this experiment was for the researcher to study one of the process of digestion which is absorption, and seeing if starch and glucose could diffuse through the dialysis tubing, and could the two be absorbed by the small intestines, and if so or not, why? To begin, in this experiment, the researchers gathered different solutions, such as, starch and glucose, filling half of each mixtures in a single dialysis tube. The researchers carefully then rinsed and pat dry the…

Photoacoustic spectroscopy (PAS) is a tool to study thermal emission resulting from non-radiative relaxation followed by absorption of radiation. PAS was studied primarily by Alexander Graham Bell, John Tyndall, Wilhelm Rontgen and Lord Rayleigh in 1884. For the history of PAS, was not until 1975 that photoacoustic spectroscopy started to be used as a wide range of different applications. This technique provides the following main advantages over the known types of spectroscopy. The advantages…

about this procedure. Knowledge of injection sites is key. In the debate of ventrogluteal injection versus dorsogluteal injection, the ventrogluteal site is triumphant. Reasons behind this include the ventrogluteal site aids better in medication absorption because of the thicker muscles, and it is safer for patients. Using the dorsogluteal site also increases the risk for sciatic nerve injury. To ensure patient safety while also providing them with exceptional care, use of the ventrogluteal site…
