Method Development and Validation of Metronidazole Using UV Spectrophotometer
Metronidazole in METRONIDAZOLE I.V. Infusion 500mg/100ml was determined by Spectrophotometric method. Being a very simple, reliable and sensitive method was developed and adopted to perform the analysis of METRONIDAZOLE I.V. Infusion 500mg/100ml. The Spectrophotometric method described was found to be simple, sensitive and accurate. Therefore this could be applied for the determination of METRO...
متن کاملNitrate reductase for nitrate analysis in water
Nitrate analysis in water is one of the most frequently applied methods in environmental chemistry. Current methods for nitrate are generally based on toxic substances. Here, we show that a viable alternative method is to use the enzyme nitrate reductase. The key to applying this Green Chemistry solution for nitrate analysis is plentiful, inexpensive, analytical grade enzyme. We demonstrate tha...
متن کاملDetermination of Nitrate in Sea Water by Cadmium-copper Reduction to Nitrite*
An accurate, dependable determination of 0-60 ,ug-at./l. of NOs -N in sea water has been developed. The sample is treated with tetrasodium ethylenediaminetetraacetate solution and passed through a column of copperized cadmium filings. A nearly quantitative reduction of nitrate to nitrite results. Nitrite is then determined by a diazotization method. Neither sulphide nor high nitrite concentrati...
متن کاملanalysis of ruin probability for insurance companies using markov chain
در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...
15 صفحه اولA method for range calculation of proton in liquid water: Validation study using Monte Carlo method and NIST data
Introduction: The main advantage of using ion beams over photons in radiotherapy is due to their inverse depth-dose profiles, allowing higher doses to tumors, while better sparing normal tissues. When calculating dose distributions with ion beams, one crucial point is the uncertainty of the Bragg-peak range. Recently great effort is devoted to enhance the accuracy of the comput...
