Uptake of L-alanine and L-phenylalanine by purified bursh-border-membrane vesicles isolated from human small intestine was investigated by using a rapid-filtration technique. L-Alanine entered the same osmotically reactive space as D-glucose, indicating that transport into the vesicle rather than binding to the membranes was being observed. The uptake rate for L-alanine was higher in the presen...

The present study was carried out to evaluate three interpolation methods including weighted moving average (WMA) with the power of 2 and 3, Kriging and Cokriging methods. Data of 23 wells in Mazandaran province were collected in fall and spring 2006. Seven parameters including electrical conductivity (EC), pH, total dissolved solids (TDS), sodium adsorption ratio (SAR), total hardness (TH), ch...

The interaction of tetratopic amidinium-containing receptors with terephthalate anions leads to porous framework materials assembled through charge-assisted hydrogen bonds. The frameworks form in good yield within minutes in water at room temperature, but no framework material is obtained if other anions (Cl-, Br-, NO3-, SO42- or isophthalate2-) are used in place of terephthalate. Two forms of ...

The electrochemical corrosion behavior of NiTi alloy electrodeposited conductive polypyrrole (PPy) coatings doped with small size sulfate (SO42 ), medium size para-toluene sulfonate (pTS ) and large size dodecylbenzene sulfonate (DBS ) counter anions has been studied by electrochemical measurements and surface analysis. It is demonstrated that PPy coatings inhibit the corrosion of NiTi substrat...

The oxidative degradation of Procion Red MX-5B by solar Fenton’s has been investigated using sunlight as irradiation source in presence of hydrogen peroxide and Fe2+. Maximum decolorization (99%) and COD removal (97%) for MX-5B was obtained at H2O2 dose of 16.6 mM and at 30 min irradiation time. Fe2+ dose of 0.36 mM was optimum for Procion Red MX-5B degradation. The solar degradation mechanism ...

This paper presents a constant-time implementation of Classic McEliece for ARM Cortex-M4. Specifically, our target platform is stm32f4-Discovery, development board on which the amount SRAM not even large enough to hold public key smallest parameter sets McEliece. Fortunately, flash memory enough, so we use it store key. For level-1 mceliece348864 and mceliece348864f, takes 582 199 cycles encaps...
