nanoporous sodium montmorillonite clay (na+-mmt) was used as a support for the immobilization of 1-methyl-3-(trimethoxysilylpropyl)-imidazolium hydrogen sulfate (na+-mmt-[pmim]hso4). this catalyst showed excellent catalytic activity for the preparation of 2-amino-3-cyano-5-oxo-5,6,7,8-tetrahydro-4h-benzopyrans via three-component reactions between aldehydes, dimedone and malononitrile. the proc...

introduction: the study was conducted to assess the school activity of thalassemic children and to reveal the relationship between school activity with the socio-demographic factors as well as clinico-therapeutic profile. methods: a total of 365 admitted thalassemic patients of burdwan medical college (ages 5 to 12 years) were participated in this cross sectional descriptive study conducted on ...

This study examines whether readers of the paper and online versions of a national newspaper acquire different perceptions of the importance of political issues. Using data from a weeklong experiment in which subjects either read the print version of the New York Times, the online version of that paper, or received no special exposure, this study finds evidence that people exposed to the Times ...

food anticipatory activity (faa) was assessed in rainbow trout ( oncorhynchus mykiss ) in two small raceways using demand-feeding (t2) and hand-feeding (t2). the fish of both raceways were subjected to restricted feeding (rf) at two times in two places and the fish distribution and/or trigger actuation, total agonistic behaviour between fish, and swimming speed were measured. food anticipatory ...

In this project various types of carbonyl compounds were efficiently converted to their corresponding 1,3-oxathiolanes  with 2-mercaptoethanol in the presence of catalytic amount of Al-MCM-41 with microwave energy. The catalyst can be reused several times without loss of its catalytic activity. Very short reaction times, reusability of the catalyst, and easy workup are noteworthy advantages of ...

[1] A one-dimensional (1-D) numerical magnetohydrodynamic (MHD) code is applied to propagate the solar wind from 1 AU through 10 AU, i.e., beyond the heliocentric distance of Saturn’s orbit, in a non-rotating frame of reference. The time-varying boundary conditions at 1 AU are obtained from hourly solar wind data observed near the Earth. Although similar MHD simulations have been carried out an...

aquatic animals are important resources for extraction of valuable compounds such as enzymes. in this study, lipase was extracted from the intestine of rainbow trout. samples were defatted with acetone several times; ammonium sulphate (60%) was used for precipitation followed by ultrafiltration for concentrating the samples. the final purification of the enzyme was performed by passing of the s...
