این پایان نامه در ابتدا به چگونگی اندازه گیری ضرایب نفوذ منفرد با استفاده از تکنیک pfg اسپکتروسکوپی nmr و تحلیل طیفها بوسیله برنامه core می پردازد و سپس با بدست آوردن ضرایب نفوذ منفرد اجزا سیستم به مطالعه سیستم سورفکتانهای triton x-100, ctab و sds می پردازد که نقاط cmc سورفکتانتهای ctab و triton x-100 بدست آمد و سپس مخلوط این دو سورفکتانت بررسی شد و وجود سینرجیسم...
An assessment is made of the dominant features contributing to the triton potential energy, with the objective of understanding qualitatively their origins and sensitivities. Relativistic effects, short-range repulsion, and OPEP dominance are discussed. A determination of the importance of various regions of nucleon-nucleon separation is made numerically.
Neptune’s largest satellite, Triton, is one of the most fascinating and enigmatic bodies in the solar system. Among its numerous interesting traits, Triton appears to have far fewer craters than would be expected if its surface was primordial. Here we combine the best available crater count data for Triton with improved estimates of impact rates by including the Kuiper Belt as a source of impac...
A common breach of network security is the class of attacks called Worm-virus. This paper proposes a language called Triton whose goal is to efficiently and effectively safeguard large network security for management system. We represent abstract language that supports various functions. This high-level language abstracts the control behavior of the network nodes, which has various setting-up m...
BACKGROUND The rapid, simple determination of surfactants in environmental samples is essential because of the extensive use and its potential as contaminants. We describe a simple, rapid chemiluminescence method for the direct determination of the non-ionic surfactant Triton X-100 (polyethylene glycol tert-octylphenyl ether) in environmental water samples. The optimized experimental conditions...
Four cell surface-exposed, integral membrane proteins from H4-II-E-3 hepatoma monolayer cultures, derivatized by the membrane-impermeant reagent sulfosuccinimidyl 2-(biotin-amido)ethyl-1,3-dithioproprionate, were resistant to extraction with Triton X-100 at 0 degrees C. Thirty-three other similarly derivatized proteins were solubilized under these same conditions. Antisera were prepared that re...
1. Lipoprotein lipase activity was measured in heart homogenates and in heparin-releasable and non-releasable fractions of isolated perfused rat hearts, after the intravenous injection of Triton WR-1339. 2. In homogenates of hearts from starved, rats, lipoprotein lipase activity was significantly inhibited (P less than 0.001) 2h after the injection of Triton. This inhibition was restricted excl...
Measurements of the surface tensions, densities and viscosities of aqueous solutions of Triton X-100 (TX-100) and rhamnolipid (RL) mixtures, at constant concentration of RL or TX-100, were carried out. The measured values of the surface tension were compared to those determined using different theoretical models and on the basis of the surface tension of aqueous solutions of individual surfacta...
SCOPE Investigations into the immunological response of proteins is often masked by lipopolysaccharide (LPS) contamination. We report an optimized Triton X-114 (TX-114) based LPS extraction method for β-lactoglobulin (BLG) and soy protein extract suitable for cell-based immunological assays. METHODS AND RESULTS Optimization of an existing TX-114 based phase LPS extraction method resulted in >...
A simultaneous determination of cationic and nonionic surfactants has been developed using ion-association titration. Tetrabromophenolphthalein ethyl ester (TBPE) was used as an indicator. Benzalkonium reacted with TBPE to form a blue ion-associate in the organic phase. When tetrakis(4-fluorophenyl)borate was added dropwise to the solution, the color of the organic phase turned to yellow at the...
