A method for the determination of selenium by ion chromatography (IC) after oxygen flask combustion has been developed and applied to the determination of selenium in bulk prednisolone. We found elemental selenium [Se(0)], selenite ion [Se(IV)] and selenate ion [Se(VI)] (ca. 5, 75 and 20%) in the absorbing liquid obtained by oxygen flask combustion of Se(0), Se(IV) and Se(VI). Se(VI) was direct...

Covid-19 encourages the use of Digital Library sources. especially for students who are completing college assignments, preparing their final project, lecturer in compling teaching material, including researchers. On other hand, technology has developed rapidly. Technological developments have changed pattern human life and business models various organizations order to survive this digital era...

A spectrophotometric method for the determination of chlorine,bromine or iodine ion by using1,5-bis(6-methy1-4-pyrimidyl)carbazone has been established.The ranges of determination were0.355-3.55ppm of Cl-,0.799-7.99ppm of Br and1.27-12.7ppm of F.The proposed method could be applied to the analyses of various halogen-containing organic compounds, including sulfur-containing compounds.Eleven comm...

It is not possible for the wax pattern of most large-volume maxillary resection obturators to be placed into a flask for conventional compression molding processing and positioning of the wax pattern. However, these wax patterns and their channel access design often can be modified and aligned in position for processing with the continuous pressure injection technique. This article describes th...

The molecular weight of ethyl acetate was determined in this experiment using a formula derived from the ideal gas law and experimental measurements of mass, volume, temperature and pressure of the sample. The molecular weight was determined to be 50 g/mol +/10% (RSD). This value compares unfavorably to the literature value of 88 g/mol [1]. RESULTS AND DISCUSSION The experiment was performed us...

Grape cultivation and wine production has been in practice since 7000 BC ancient China. Today, top producing countries are France, Italy, Spain, including the United States. New York State is third largest state US, with over 28 million gallons produced 2017. Wine pomace, residue from making after pressing could be used for of electricity heat replacing fossil resources. One alternative route a...

In this paper, Isopropanol (IPA) availability during the anisotropic etching of silicon in Potassium Hydroxide (KOH) solutions was investigated. Squares of 8 to 40 μm were patterned to (100) oriented silicon wafers through DWL (Direct Writing Laser) photolithography. The wet etching process was performed inside an open HDPE (High Density Polyethylene) flask with ultrasonic agitation. IPA volume...

Establishment of a near-linear temperature gradient in an incubator has been accomplished by the application of heat to one terminus of a conducting body, normally a metal bar, and the removal of heat from the other terminus of the conducting body. Such incubators have been complex and unwieldy because of the need for mechanical refrigeration. We have described a simplified temperature gradient...

In this paper, a numerical study to assess the dosimetry of an in vitro exposure setup at the intermediate frequencies (IF) is presented and validated. The setup is able to reproduce any complex magnetic induction (B) field waveform using a couple of square coils. In our work, actual signals generated by a 1.5 T magnetic resonance imaging (MRI) apparatus were exploited. Firstly, the simulated B...
