this study was undertaken for the purpose to determine the concentration of caffeine in eight brands of soft drinks with the use of an Ultraviolet spectroscopy. This told us about the best brand among the different brands containing caffeine. The highest concentration of caffeine was found in Sting 500mL (560.29 µg/mL), so it is strongest CNS (central nervous system) stimulant among all samples and it is harmful for health. The lowest concentration of caffeine was found in 7up 500mL (29.71 µg/mL). So it is a weakest stimulant among all samples and can be sold in market
Optimization the production of extracellular lipase in culture of Bacillus cereus has been investigated. From 10 samples of diesel fuel polluted soil it was found that 3 samples was positive for the presence of B. cereus. Lipase production by B. cereus isolated from diesel fuel polluted soil was investigated and optimized. The enzyme production was increased with increasing time and maximum enzyme activity was obtained after 72 hrs of incubation. Effect of pH and temperature indicated that, the lipase production was maximum at pH 8.0 (60.2 U/ml) and at 35°C (55.25 U/ml). The lipase production was optimized in shake flask experiments. With a selected carbon sources, maltose (65.5 U/mL) and nitrogen source, peptone (66.25 U/mL) was suitable substrates for accelerating lipase production. The present study indicates that the various factors influenced enzyme production by the bacteria, it appears that the nature of the supplements had significantly influenced on the produc
Phonics skills are considered to be the predictors of reading disability, which is off late viewed as a language based disorder. The aim of the present study is to compare the phonics skills of high and low academic achievers across Bengali and English. A checklist consisting of three parameters was developed in both the languages to assess phonics skills. A total of 42 normally developing bilingual females who attended standard three to standard five in the age range eight to eleven years participated in the study. The participants were classified as high and low academic achiever based upon school performance. Significant differences were found in all the phonics skills in both the languages except vowel sound skill in Bengali and letter name in English. It is concluded that phonics tasks should be provided importance and during classroom curriculum as it distinguishes between high academic achievers from the low academic achievers.
The purpose of this study was to determine the concentrations of toxic metals (Cd, Hg, Cr, Pb, As) in meat at the Kumasi Central Abattoir, Ghana by using a Varian 220 Atom Absorption Spectrophotometer. The levels of toxic metals in meat (cow, pig, sheep, goat, grass cutter, deer) varied in concentration. The concentration of lead was above the tolerance level in all the meat samples with the highest concentration recorded in beef at 1.154 mg/kg and the lowest at 0.037 mg/kg in pork. The amount of mercury, Hg observed in the various meat samples fell within the range of 0.059 mg/kg to 0.012 mg/kg, a little over the tolerable level of 0.05 mg/kg. The highest mercury, Hg concentration was observed in grasscutter meat (0.071 mg/kg) and the lowest concentration in pork, which was observed at 0.012 mg/kg, with the former above the permissible limit and
Car Accidents often result in injuries to the parties involved. In 2012 alone, North Carolina reported over 100,000 car accident injuries and over 1,200 fatalities.
November is COPD Awareness Month. COPD stands for Chronic Obstructive Pulmonary Disease. COPD is a common lung disease and consists of two main forms, Chronic Bronchitis and Emphysema.
