Drying kinetics of Cape gooseberry was studied and modeled during processing at four temperatures (60, 70, 80 and 90C). Desorption isotherm was obtained at 40C giving a monolayer moisture content of 0.086 g water/g d.m. Experimental drying curves showed that drying process took place only in the falling rate period. Several thin-layer drying models available in the literature were evaluated bas...

To unveil the mechanism of fast autooxidation of fish myoglobins, the effect of temperature on the structural change of tuna myoglobin was investigated. Purified myoglobin was subjected to preincubation at 5, 20, 50 and 40C. Overall helical structural decay through thermal treatment up to 95C was monitored by circular dichroism spectrometry, while the structural changes around the heme pocket w...

The large (7 m×4 m cylinder, 84 m3) AIDA (Aerosol Interactions and Dynamics in the Atmosphere) cloud chamber facility at Forschungszentrum, Karlsruhe, Germany was used to test the ice nucleating ability of two desert dust samples from the Sahara and Asia. Aerosol samples were lognormally distributed with a mode diameter of 0.4(±0.1)μm and geometric standard deviation of ∼1.7(±0.2). At temperatu...

The extremely halophilic archaeon Natrinema sp. strain SSBJUP-1, which produces extracellular cellulase and xylanase, was isolated from the Lonar Lake situated in Buldhana, Maharashtra. The enzymes were optimally active at pH 9–10 and temperature 40–60 C and they were most stable up to pH 11 and 16 % of NaCl concentration. The xylanase showed maximum activity at 50C and cellulase at 40C. Xylana...

A nitrogen-containing carbon (N-C) film was synthesized by pyrolysis of vapor phase polymerized polypyrrole (PPy). This carbon film exhibits excellent rate capability and cyclability as a lithium-ion battery anode. The reversible capacities are 908.4, 825.7, 664.0, 531.6, 415.5 and 325.9 mA h g(-1) at 1C, 2C, 5C, 10C, 20C and 40C, respectively.

KCNQ1 and KCNE1 (Q1 and E1) associate to form the slow delayed rectifier I(Ks) channels in the heart. A short stretch of eight amino acids at the extracellular end of S1 in Q1 (positions 140-147) harbors six arrhythmia-associated mutations. Some of these mutations affect the Q1 channel function only when coexpressed with E1, suggesting that this Q1 region may engage in the interaction with E1 c...
