Biological Importance of Metal Complexes of Pyrimidine-2-Thione - Research Paper Example Mo205L2(H2O)2.H2O (1)preparation. (5cm3)Aqueous solution of (NH4)2(MoO4) which is 0.24g and 1.0mmol respectively is added to LH solution in 25cm3 of EtOH (Speziale, 1963). The resultant slurry is subjected to heat, and the resultant solution, orange in color, is refluxed for duration of 4hours (Harris & Bertolucci, 1989). In this time duration, orange precipitate is realized (Foster & Snyder, 1963). The solid is then collected through filtration, immediately thereafter washed in 2cm3 of ethanol and diethyl ether, and then dried through vacuo (Wells, 1984). The yield is 35%, based on metal (Podson & King, 1945). Elemental analytical computation for the C8H16N8O10S2Mo: S, 10.00; C, 15.00; N, 17.50; H, 2.50%; illustrate that N, 17.51; C, 14.98; N, 17.51; H, 2.82; and AM(DMSO) 3 S cm2per mol (Greenwood & Earnshaw, 1997).  W2O5L2(H2O)2.H2O (2) preparation (Anthony, 2007). This uses (NH4)2(WO4) and uses the same method applied in the first procedure (Peter, 2003). In this procedure, a br ight yellow substance is isolated (Petricci et al, 2002). The yield is 50% metal based (Housecroft & Sharpe, 2005). The elemental analytical computation for C8H16N8O10S2W: H, 1.96; S, 7.85; C, 11.77; N, 13.73%, indicates that C, 11.62; S, 7.95; N, 13.77; H, 1.90%; and AM(DMSO) 2 S cm2per mol (Cotton et al, 1999).   In analyzing the antimicrobial activity; the bacterial strains were cultured in the nutrient agar slants (De Vito et al, 2005).

Capstone project - Research Proposal Example It is the mandate of all nurses who deals with such patients to ensure that their safety if prioritized. This proposal seeks to address this issue by making sure that it is mandatory for all practicing nurses who deal with such patients of stroke, to administer dysphagia tests immediately a patient is admitted in the hospital before giving them any food substances. For this project, I will use an evidence based model. For effective results, in this research, I have used the conduct and utilization of research in nursing model (CURN) since the model seeks to carry out a research which gives findings to s particular behavior which improves the patients’ health outcome. (Scmidt, 2014)Similarly, conducted over a period of two weeks, this research seeks to prove that Dysphagia screening saves lives of persons who suffer from stroke on admission to hospitals. Many stroke patients need critical attention. Ensuring their safety while they have been admitted is one of the nurses’ most important things. The manner in which stroke patients are handled on arriving at the hospitals needs to be addressed. Most of the nurses do not carry out dysphagia screening as recommended for all stroke patients in the AHA/ASA guidelines (Stephenie, 2013). Some nurses go to the point of giving these patient foods without having the swallowing tests done on them prior to this. According to the data collected from my experience, only 3 out of 4 patients go through the swallowing tests. This means that the safety of the remaining patients is not prioritized. For the reason that nurses fail to carry out this necessary test, an estimated 50,000 die every year due to aspiration pneumonia after stroke. Evidently, most of these deaths can therefore be avoided by carrying out this test. The problems with swallowing in these patients are associated with a higher mortality rate (Jeff, 2013). Moreover, technologies have evolved which enable the patients to be screened for dysphagia
