Abstract: Present study revealed that during period of highly floral scarcity (May and June) Apis mellifera showed foraging activity on Parthenium hysterophorus which is considered worst weed for environment and human health. Average foraging activity was recorded 4.9 bees/m²/min. Maximum abundance of foraging bees (13 bees/m²/min.) was observed from 800 to 845 hours. Average foraging frequency of bees was found to be 48.1 flowers/min. but maximum number of flowers visited/ min. was noted to be 60 from 815 to 845 hours. Average pollen load was 5.28 mg/bee. So this weed serves as subsistence flora at very critical time of dearth. Keywords: Parthenium hysterophorus, Apis mellifera, Foraging behaviour of bees, pollen collection.

Abstract: Myotonic dystrophy type 1 or Steinert's disease is the most common form of adult muscular dystrophy affecting multiple systems with a wide spectrum of phenotypes. This paper focuses on the different methods to diagnose myotonic dystrophy type 1 that have been used over the years and the various modifications that have been made to the previous diagnostics. The different diagnostic assays and their different advantages and disadvantages are discussed.

Abstract: The amino acid composition of yellow and brown tiger nut (Cyperus esculentus) milk preparations and their mixtures were studied. The mixed variety was prepared from mixing equal proportion of the two varieties. The milk preparation was obtained by blending and subsequent expression of the milk.. Protein analysis stated with the hydrolysis of the milk preparation with HCl for 23hrs and the resulting amino acids were quantified with amino acid analyzer (Technicom TSM-1). The % nitrogen for the yellow, Brown and the mixture are 3.72, 3.24 and 2.22 respectively. Arginine has the highest value of 15.87, 16.22 and 19.20 g/100g respectively conferring same order of amino acid basicity. Methionine and tyrosine are the lowest (0.60 and 0.63, 0.68 and 0.48, 0.49 and 0.48 g/100g protein) respectively. Tryptophan is not prominently associated with the myriad of essential amino acids of tiger nut milk. It was not detectable in any of the varieties. The overall result of the study showed that the tiger nut milk is a rich source of protein. It can also be consumed as a valuable substitute for conventional cow milk and other known milk sources. The milk prepared from mixed variety exhibited synergistic effect as it combined some beneficial amino acid that either of the two varieties lacks. Keywords : Tiger nut, milk, amino acid, synergistic effect, protein

Abstract: Aspirin is easily hydrolyzed by water and it is therefore produced by slugging, which is a time consuming process. This work was aimed at studying the effect of humidity on the physical properties of aspirin tablets produced by melt granulation in comparison with conventionally produced aspirin tablets. Goat fat (1 to 2% w/w) and carnauba wax (2 to 7.5% w/w) were the waxes used as granulating agents in the melt granulation technique. The granules were characterized and the ones with adequate flow were compressed to tablets of diameter 13.8± 0.1 mm and thickness 3.2 ± 0.1mm using a single punch tableting machine. Resulting tablets were evaluated and then stored under ambient humidity and 1% relative humidity and the effect of the storage on the physical properties of the tablets were analyzed monthly for two months duration. The bulk and tapped densities of the granules were between the ranges of 0.62 ± 0.00 - 0.71 ± 0.01 g/cm3 and 0.77 ± 0.02 - 0.85 ± 0.00 g/cm3 respectively. The angle of repose ranged from 26.96 ± 0.07o - 39.21 ± 0.02o, Carr's index between 10.34 ± 0.14 and 21.88 ± 0.01 and Hausner's ratio being in the range of 1.12 ± 0.05 - 1.28 ± 0.11. The resulting tablets displayed a good disintegration, having disintegration time ranging from 2.28 ± 0.12 - 5.30 ± 0.13 min. Tablet friability and tensile strength ranged from 1.09 ± 0.05 - 3.10 ± 0.01% and 0.02 ± 0.01 - 0.07 ± 0.00 MNm-2 respectively. After storage there was no change in tensile strength, however, there was a change in disintegration time and friability ranging from 0.46 ± 0.05 – 5.50 ± 0.08 min and 1.25 ± 0.01 - 3.50 ± 0.10% respectively. Melt granulation, which is a simpler method, had the least influence of humidity on the physical properties of aspirin tablets.
