The aim of the present study was to get a total physical and chemical characterization and comparison of the principal components in Bangladeshi buffalo (B), Holstein cross (HX), Indigenous cattle (IC) and Red Chittagong Cattle (RCC) milk. Protein and casein (CN) composition and type, casein micellar size (CMS), naturally occurring peptides, free amino acids, fat, milk fat globule size (MFGS), fatty acid composition, carbohydrates, total and individual minerals were analyzed. These components are related to technological and nutritional properties of milk. Consequently, they are important for the dairy industry and in the animal feeding and breeding strategies. Considerable variation in most of the principal components of milk were observed among the animals. The milk of RCC and IC contained higher protein, CN, ${\beta}$-CN, whey protein, lactose, total mineral and P. They were more or less similar in most of the all other components. The B milk was found higher in CN number, in the content of ${\alpha}_{s2}-$, ${\kappa}$-CN and ${\beta}$-lactalbumin, free amino acids, unsaturated fatty acids, Ca and Ca:P. The B milk was also lower in ${\beta}$-lactoglobulin content and had the largest CMS and MFGS. Proportion of CN to whey protein was lower in HX milk and this milk was found higher in ${\beta}$-lactoglobulin and naturally occuring peptides. Considering the results obtained including the ratio of ${\alpha}_{s1}-$, ${\alpha}_{s2}-$, ${\beta}$- and ${\kappa}$-CN, B and RCC milk showed best data both from nutritional and technological aspects.

A.S.M. Badrudduza,S.H. Islam,M.K. Kundu,I.S. Ansari 한국통신학회 2023 ICT Express Vol.9 No.2

In this paper, the physical layer security aspects of a wireless framework over shadowed (AKMS) fading channel are examined by acquiring closed-form novel expressions of average secrecy capacity, secure outage probability (SOP), and strictly positive secrecy capacity. The lower bound of SOP is derived along with the asymptotic expression of SOP at the high signal-to-noise ratio regime in order to achieve secrecy diversity gain. Capitalizing on these expressions, the consequences due to the simultaneous occurrence of fading and shadowing are quantified. Finally, Monte-Carlo simulations are demonstrated to assess the correctness of the expressions.

The aim of this study was to scrutinize thephysicochemical and qualitative microbial examination of 30 different (of various dosage forms) herbal medicinalproducts marketed by pharmaceutical and herbal manufacturersin Bangladesh. The microbial evaluation includedtotal viable aerobic bacteria, Escherichia coli, fungi andStaphylococcus aureus count; physicochemical propertieslike weight variation, hardness, disintegration time, friabilityand density. The IMViC (indole, methyl red, Voges–Proskauer and citrate utilization) tests were frequentlyemployed for identification of E. coli and S. aureus. Totalviable aerobic bacterial counts in the samples analyzed wereranged from 3.8 × 10⁴ to 3.2 × 108 CFU/ml or CFU/g and 36.67 % were within BP standard limit. S. aureus wasdetected in 53.33 % (16) of the samples, ranged from anestimated 3 × 10² to 9.2 × 106 CFU/ml or CFU/g whichwere above the USP standard. E. coli was detected in 40 %(12) of the samples, ranging from 1 × 10² to 4.8 × 10⁴CFU/ml or CFU/g that were above the USP standard. Theranges of the fungi counts were 3.4 × 10³ – 3.1 × 106 CFU/ml or CFU/g and 46.67 %of which were within BP standard. Physicochemical properties of herbal products manufacturedby pharmaceutical manufacturers were found betterthan that of the herbal manufacturers. From the label andpack insert of herbal products, definite release patterninformation weren’t obtained and the majority of herbalproducts showed scattered disintegration time. In order toreduce the potential health related complications, there isnecessity of constant monitoring and control of the standardsof herbal medicine products available in the Bangladeshimarket.

Hassanuzzaman, M.,Ahammad, M.U.,Bulbul, S.M.,Nurul Alam, A.M.M.,Islam, M.A. Asian Australasian Association of Animal Productio 2004 Animal Bioscience Vol.17 No.11

An experiment was carried out with day-old "Sonali" (♂RIR$\times$♀Fayoumi) chicks to investigate the efficacy of locally made low cost brooders for brooding chicks in rural areas. Three types of indigenous brooders viz. charcoal, haricane and sawdust brooders were used for brooding chicks throughout the experimental period of 28 days. The efficiency of the brooders was observed in respect of their ability to maintain temperature, fluctuation in temperature during operation and cost effectiveness. Following initial trial of temperature maintenance for 48 h, the chicks were put under the brooder stoves and brooded up to 28 days. The experimental birds were fed on chick starter diet. Maintenance of temperature with sawdust brooders was found satisfactory and optimum for brooding the chicks at different stages of brooding and at the same time involved least cost for brooding in comparison with charcoal and haricane brooders which did not perform well in generating heat necessary for brooding and were not economically feasible for poor farmers. On the other hand, performance of charcoal brooders was better in respect of temperature maintenance during initial stage (when the brooder was started) but the temperature fluctuated rapidly, whereas fluctuation of temperature was gradual in sawdust brooders. Body weight gain and feed conversion were best in sawdust brooders. Survivability was highest in sawdust brooders and lowest in haricane brooders. Sawdust brooders may be appropriate for brooding chicks in rural areas, where electricity is not available.

Amin, M.R.,Husain, S.S.,Islam, A.B.M.M.,Saadullah, M. Asian Australasian Association of Animal Productio 2001 Animal Bioscience Vol.14 No.7

A field trial on selection for increased live weight in Black Bengal (BB) goat was conducted over two generations. Parents of both sexes were selected (mass selection) based on mature body weight criteria set against age. A parallel randomly mated line was maintained to compare the response (R) of selection at birth. 3, 6, 9 and 12 months of age in both generations. Lactation yield (LY), average per day yield (APDY) and lactation length (LL) were evaluated in the selected line in comparison to randombreds as a result of correlated response. Live weights were significantly improved at onward bir:th in first generation and only at birth in second generation. Improvements (%) in live weight at 3, 6. 9 and 12 months in first generation were 17.6, 18.4, 16.6, and 12.0 at birth in second generation. Significant correlated R were found in LY and APDY. Results suggest that there may be a positive relationship between live weight and lactational traits in BB goats of Bangladesh. It was also concluded that such a field scheme can be effectively used for genetic improvement of goats in subsistence farming, at least for short term gain.

( M. Z. Islam ),( M. A. Mele ),( M. J. Jeong ),( I. S. Kim ),( S. K. Hong ),( I. L. Choi ),( J. P. Baek ),( H. M. Kang ) 강원대학교 농업생명과학연구원(구 농업과학연구소) 2014 강원 농업생명환경연구 Vol.26 No.3

This study was conducted to find out the performance of silicon foliar spray treatment on storability of truss tomatoes (Lycopersicon esculentum Mill. cv. Campari and Temptation) in MA (20,000 cc/m2 · day· atm O2 permeability film) storage. Tomatoes were grown by hydroponics at Gangwon province in Korea during the winter, harvested at light red maturity stage and packaged with MA condition for stored at 8℃ and to investigate the storability. The silicon sprayed as a whole plant that displayed the utmost visual quality had the oxygen 5.94-12.28%, carbon dioxide 6.72-7.94% and ethylene concentration around 0.43-1.67 μL/L of ‘Campari’ and the oxygen 3.82-10.84%, carbon dioxide 7.40-10.20% and ethylene concentration around 0.69-1.75 μL/L of ‘Temptation’. The range of fresh weight loss of ‘Campari’ was less than 0.22% and ‘Temptation’ was less than 0.20% during the storage period at 8℃. The higher visual quality maintained by silicon sprayed as a whole plant than other treatments of both cultivars on the MA storage period at 8℃. The silicon sprayed as a whole plant had a positive effect to reduce the fungal incidence of both cultivars during the MA storage period at 8℃. Moreover, the silicon sprayed as a whole plant showed more prominent firmness than other treatments for storage days of both cultivars. Therefore, the silicon foliar sprays as whole plant has the positive effect to advance storability, reduced fungal incidence, maintained vitamin C, soluble solids and retain firmness.

Coloration of polyester fiber with natural dye henna (Lawsonia inermis L.) without using mordant: a new approach towards a cleaner production

M. A. Rahman Bhuiyan,A. Ali,A. Islam,MA Hannan,S. M. Fijul Kabir,M. N. Islam 한국의류학회 2018 Fashion and Textiles Vol.5 No.1

The demand of natural colorants for the dyeing of textile fbers has been increasing gradually in recent years due to a growing global ecological awareness as well as a greater emphasis on a cleaner and greener production process. The eco-friendly dyeing of polyester fber with natural dye henna is a novel approach that has extensively been studied in this article. To this end, the dyeing of polyester fber with henna dye was conducted at diferent temperatures without using hazardous metallic mordants. Then the dyeing performance was investigated in terms of depth of shade measurement, analysis of colorimetric properties of color and assessment of color fastness properties of henna dyed polyester fabric samples. The amount of dye absorption by fber and the resulting depth of shade were found to increase with increasing dyeing temperature. In case of colorfastness properties, all dyed substrates demonstrated excellent fastness ratings against washing, rubbing and perspiration with little to no deterioration of color. Moreover, the detailed morphological study revealed that surface structure of fber remained unchanged after dyeing at an elevated temperature and pressure. So, the fndings suggest that dyeing of polyester fber with henna dye without any metallic mordants is a promising approach to get the desired dyeing performance alongside opening up an avenue for eco-friendly dyeing.

Genetic Analysis of Three River Populations of Catla catla (HAMILTON) Using Randomly Amplified Polymorphic DNA Markers

Islam, M.S.,Ahmed, A.S.I.,Azam, M.S.,Alam, M.S. Asian Australasian Association of Animal Productio 2005 Animal Bioscience Vol.18 No.4

The genetic variations in three major river populations viz. the Halda, the Jamuna and the Padma of the Indian major carp, Catla catla were analyzed by Random Amplified Polymorphic DNA (RAPD) markers. Four decamer primers were used for amplifying DNA of 10 individuals from each population. The proportion of polymorphic loci and the gene diversity estimates were 59.4 and 0.20 for the Halda, 37.5 and 0.14 for the Jamuna and 46.9 and 0.16 for the Padma populations respectively indicating the existence of a relatively high level of genetic variation in the Halda river population. The inter-population similarity indices, gene flow and genetic distance values indicated that the Jamuna-Padma population pair of catla was genetically closer than the Halda-Jamuna and the Halda-Padma population pairs in compliance with the geographical distances among them. The coefficient of gene differentiation ($G_{ST}$=0.13) reflects some degree of genetic differentiation among three populations of catla studied. The data suggest that the RAPD technique could be used to discriminate different river populations of catla.
