Calcium Absorption Essay Example for Free

Calcium Absorption Essay In order to determine the content of calcium and magnesium in an unknown sample of limestone, the utilization of atomic absorption spectrophotometry can help in deciphering the unknown concentrations of each molecule in the limestone sample. Atomic absorption spectrophotometry, emits radiation of the correct frequency that is passed through a flame and the intensity of the transmitted radiation is measured?. The calcium concentration or ppm can be measured using the absorbance of the solution and comparing it to a standard curve for calcium?. Whereas magnesium, needs to be determined using the standard addition method. The concentrations of each respective molecule can be presented as CaO and MgO percentages of the unknown limestone sample. Materials and Methods The compound calcium carbonate (CaCO3, CAS: 471-34-1, 204. 89ppm) was utilized to compare its absorbance to the unknown sample of limestone # 8066 on the standard curve. Moreover, magnesium sulfate heptahydrate (MgSO4*7H2O, CAS: 10034-99-8, 40. 8ppm) was also utilized to compare its absorbance against that of the unknown. Lab personnel from the CSU Eastbay department of chemistry stockroom performed all calibrations on the Perkin Elmer AAnalyst 300 atomic absorption spectrometer. All chemicals used in this experiment were obtained from the CSU Eastbay department of chemistry stockroom. A Denver Instrument Co. Sargent-Welch analytical balance was used to determine the mass of the unknown, mass of calcium carbonate, and mass of magnesium sulfate heptahydrate. A Perkin Elmer AAnalyst 300 atomic absorption spectrometer equipped with a Lumina Calcium and Magnesium Lamp was used to determine the absorbance. The instrument used Argon and Acetylene as the carrier gas and oxidant gas, respectively. Calcium Absorption. (2018, Oct 17).

Sex addiction - Essay Example gh sexual dysfunction (problems that interfere with the ability to have sex) are often seen as a greater psychological problem, sexual addiction is a dangerous disease that can destroy the lives of individuals, their families, and their friends.

Researchers have a difficult time trying to determine a specific percentage of involved individuals because many of the acts are illegal and reporting methods typically are unreliable† (Bellnir, 2005, p. 328). This is the case for any kind of sexual disorder, because the stigma involved with sexual problems prevents many people from discussing their problems or seeking help. Usually when we talk of sexual addiction, we are referring to behaviors that involve compulsive sexual acts, most likely with a variety of partners, particularly when the sexual behavior has the nature of upsetting the person engaging in it, or otherwise negatively affective his or her life (even if they cannot admit the problem). The DSM-IV categorizes sexual addiction with other miscellany at 302.9 Sexual Disorder Not Otherwise Specified.

Sonoco is a 100 year old organization that have survived wars and repeated economic crises. It is also a paternal organization that values relationship rather than performance. Sonoco will be examined in this thesis to assess how the value of human resource management will be applied. Background The growing role of Human Resource Management in organizations (Losey, Meisinger, & Ulrich, 2005) that enable it to play an important role in strategic initiatives cannot be made more apparent that in the case of Sonoco. For the better part of the last one hundred years Sonoco packaging company have successfully achieved uninterrupted growth coupled with impressive financial success. However, the past several glob al crises have also affected the primary customers of Sonoco that contributed to a drastic reduction in its fiscal performance.
