OCTOBER 2003 AMERICAN METEOROLOGICAL SOCIETY | G reat effort is continually being made to improve the parameterization of clouds in global circulation models (GCMs), and as a result the physical realism of cloud parameterizations has been improved considerably. Almost all GCMs now use a prognostic equation to represent the evolution of cloud condensate (e.g., Sundqvist 1978; del Genio et al. 19...

The lipid profiles and fatty acid composition of fish eggs (roes) from two common freshwater fish species viz., catla (Catla catla) and mrigal (Cirrhinus mrigala) have been studied. The total lipid of the egg was extracted using chloroform/methanol (2:1, v/v) and was separated into neutral lipids, glycolipids and phospholipids using silica gel column chromatography. The fatty acid composition o...

Dynamic Head Space methodology was applied to evaluate the possible contribution of some volatile compounds to the development of boar taint in pig backfat samples with low concentrations of skatole and androstenone, but which had previously been classified as tainted by a trained test panel. Volatile compounds were collected in a trap of graphited charcoal and analysed by GC-MS in Scan mode. A...

Abstract. The occurrence of climate warming is unequivocal, and is expected to be experienced through increases in the magnitude and frequency of extreme events, including flooding. This paper presents an analysis of the implications of climate change on the future flood hazard in the Beijiang River basin in South China, using a variable infiltration capacity (VIC) model. Uncertainty is conside...

Suhu kolom Gas Chromatography-Mass Spectrometry (GCMS) merupakan salah satu variabel yang harus diperhatikan pada analisis senyawa kimia, agar terpisahkan dengan baik. Penelitian ini bertujuan untuk menentukan suhu terprogram optimum asam lemak menggunakan instrumen GCMS. Sampel digunakan berasal dari hasil ekstrak mikroalga Chlorella. Ekstrasi Chlorella dilakukan cara sonikasi selama 60 menit ...

The pheromone biosynthetic pathway for production of the sex pheromone disparlure, 2-methyl-7R,8S-epoxy-octadecane, was determined for the gypsy moth. Each step in the pathway was followed by using deuterium-labeled compounds that could be identified by using GCMS. This approach provides unequivocal determination of specific reactions in the pathway. It was shown that the alkene precursor, 2-me...

during the 1970s made possible the observation of the seasonally shifting patterns of global precipitation. It was not until recently, however, that the record could be considered long enough to investigate longer-term trends and the relationship between global precipitation and global warming. Using data from the Special Sensor Microwave Imager (SSM/I) instrument, Wentz et al. [2007] reported ...

Present work is directed toward the isolation and identification of biological active (antimicrobial) compound from metabolite extracted from endophytic fungus Emericella qaudrilineata(RS-5) (Accession number KC662361). Crude extracted from endophytic fungus Emericella qaudrilineata possessing antibacterial activity was subjected to bioassay guided fractionation in which toluene fraction exhibi...
