シミュレーションデータ
1.通常のブリッジ抵抗回路シミュレーション

トランスの表現、ワイヤレス給電の表現において、結合係数Kが活用されます。結合係数の値の最大値は「1」です。1で100%の伝達を示します。現実の回路において、100%の伝達はありえませんので、電源回路のトランスの場合、0.9999の値を推奨します。また、コイルについては、2個の設定だけではなく、任意に結合させる対象となるコイルを増やすことができます。

ethanol experiment TinaCampbell37

This method uses a redox titration to determine the ethanol concentration in alcoholic beverages like beer and wine. Ethanol in a diluted sample is oxidized by dichromate overnight. The excess dichromate is then titrated with thiosulfate using a starch indicator. The titration results are used to calculate the original ethanol content. Beer samples are diluted 1:20 and wine samples 1:50 before the overnight oxidation and subsequent titration steps.

ICP PresentationK Thambi durai

This document summarizes a training presentation on inductively coupled plasma-optical emission spectroscopy (ICP-OES) given to CRCL Group A officers. The presentation covers the basic principles and instrumentation of ICP-OES, including sample introduction using nebulization, plasma generation using a radio frequency coil, excitation of atoms in the plasma, and emission detection using a photomultiplier tube. Applications discussed include clinical, environmental, pharmaceutical and industrial analysis, as well as specific examples analyzing metals in CRCL samples such as estimating elements in alloys and heavy metals in oils and minerals. The document provides details on sample and standard preparation, microwave digestion of samples, and calculations for determining unknown sample concentrations from ICP-O

Tables for Group TheoryDharma Initiative

This document provides character tables and other group theory information for various point groups. It includes: 1. Character tables for common point groups like Cn, Dn, Cnv up to n=8. 2. Tables on direct products of irreducible representations for selected point groups. 3. Information on descent in symmetry and subgroups. 4. General formulas, worked examples, and illustrations of point groups and molecules.

Determination of ascobic acid by coulometerchamith herath

This experiment determined the concentration of ascorbic acid using constant current coulometry. Ascorbic acid was oxidized at the anode according to the reaction: C6H8O6 → C6H6O6 + 2H+ + 2e-. The quantity of electricity required to oxidize known amounts of ascorbic acid was measured. A linear relationship between the amount of ascorbic acid and the quantity of electricity passed indicated the method followed Faraday's law. The concentration of ascorbic acid in an unknown sample was then determined using this relationship. Current efficiency was found to be 145.5%, higher than the required 100% for an accurate determination.

Dry AshingKassa Belay

This study validated a dry ashing method for determining levels of heavy metals like lead, cadmium, and chromium in common Ethiopian spices using atomic absorption spectroscopy. Samples of fenugreek, black cumin, garlic, and ginger were collected and ashed at 500°C for 5 hours before dissolving in nitric acid. Calibration curves were prepared and used to determine metal concentrations. Lead, cadmium, and chromium levels in the samples were found to be below recommended safety limits. The dry ashing method provided clear digests and was validated through recovery tests and analysis of variance.

11 kf-theory jntu pharmacyDr. Suman Pattanayak

This document discusses Karl Fischer titration methods for determining water content. It covers the KF reaction, volumetric and coulometric titration techniques, endpoint indication, drift correction, parameters, and KF instrumentation. Volumetric titration uses an iodine titrant while coulometric generates iodine via electrolysis. Both methods indicate the endpoint potentiometrically and use drift as a secondary check. Parameters like dynamics, stop criteria, and currents must be optimized. Common KF titration instruments include the Titrino, Titrando, Coulometer, and oven systems.
