Determination of tryptophan with N-bromosuccinimide using the stopped-flow method.

Flow injection chemiluminescence determination of N-bromosuccinimide and N-chlorosuccinimide.

buckling of viscoelastic composite plates using the finite strip method

در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....

A new method for the determination of dithiocarbamate fungicides using n-bromosuccinimide reagent

A simple and convenient method has been developed for the determination of Dithiocarbamate fungicides e.g. Ziram, Thiram, Ferbam, Zineb and ZDC in technical form and in their formulations. Aliquots containing 1-5 mg of the sample were taken in a 100ml conical flask and 5ml of 0.02 N,N-Bromosuccinimide (NBS), 10ml of glacial acetic acid and 5ml of 4 N HCI were added to it. The contents were shak...

Flow injection chemiluminescence determination of amino acids by oxidation with N-bromosuccinimide.

Reactivity of the tryptophan residues in bovine pancreatic deoxyribonuclease with N-bromosuccinimide.

DNase, containing 3 tryptophan residues, can be inactivated by modification of this amino acid with Nbromosuccinimide. Chromatography of acid hydrolysates shows all three tryptophan residues modified by the time inactivation is complete. However, spectrophotometric measurement indicates that only 2 residues are modified. The discrepancy is due to the unreliability of the spectrophotometric meth...
