Abstract

It goes without saying that Garments industry of Bangladesh has drawn a special attention to the mass people in the world because of being both cost leader and quality leader at the same time. The purpose of this research paper is to analyze the garments industry in Bangladesh which is going to be an emerging tiger in the world economy. It also aims to assess the impact of macro-environmental factors affecting the industry by PESTEL analysis. Again, five forces model has been analyzed to assess the impacts of competitive external factors on the Garments industry in Bangladesh. Furthermore, Garments sector competitive responses to the primary issues affecting the industry have been evaluated here. It also outlines the primary external influences to which this industry is subject. In this case, SWOT analysis has been conducted to assess the competitive position of this industry in comparison with the global perspective. The study suggests that total export is highly correlated with the exports of garments. It also finds that there is severe lacking in the safety and security compliance, wages and compensations and code of conduct of the current organizations. Moreover, GSP facility withdrawn can impact severely on the ready made garments of Bangladesh to compete with price in the international market with China, India and Vietnam etc. The ready made garments sector of Bangladesh is enjoying cost leadership as a source of completive advantage because of cheap labor. Finally, the study would like to recommend for further improvement of garment sector in Bangladesh.

Abstract

The purpose of the study is to identify the impact of some assumed dimensions as vital reasons for investment sluggishness in Bangladesh resulting stabilized GDP growth rate around 6 percent over last decade in spite of having some favorable microeconomic and macroeconomic indicators such as controlled inflation rate, huge foreign exchange reserve, export growth etc. The study is descriptive in nature where correlation, regression and trend analysis have been conducted from the data of primary and secondary sources. The result of the analysis shows that mainly five important dimensions of investment sluggishness named high lending interest rate, corruption in public and private organizations, political unrest, inadequate power generation and supply and infrastructure problem are significantly affecting investment sluggishness in Bangladesh resulting stabilized GDP growth rate. At the end of the research paper, some measures have been recommended to overcome the obstacles of investment growth.

Abstract

The purpose of the study is to identify the main reasons of money laundering in Bangladesh among the twenty seven predicate offences of money laundering prescribed by Bangladesh Bank and position of Bangladesh among South Asian Countries regarding anti-money laundering practices. Besides, an anti-money laundering model has been developed to combat against money laundering as 14 percent bankers think that only existing know your customer form and transaction profile of banking sector are not enough to detect money laundering. To conduct the study, 91 bankers have been surveyed to take response through structured questionnaire regarding their opinion about the predicate offences of money laundering and sufficiency of existing KYC form of banking sector to detect money laundering. From the responses, factor analysis, test of hypothesis, correlation and regression analysis have been conducted using SPSS software. The study identifies that predicate offences of money laundering can be minimized mainly through scrutinizing the activities of local criminals with foreign network and strict anti-corruption measures through automation in National Board of Revenue, strict policy adoption of criminal detection and support from foreign experts. Besides, regression model shows that only six predicate offences of money laundering explains 87.2 percent of money laundering that should get more emphasize to combat against money laundering. From the comparative analysis, it has been found that Bangladesh in holding better position just after India among six South Asian Countries according to Basel AML Index score. This study provides a complete understanding of the position of Bangladesh in case of money laundering and anti-money laundering practices. The integration of four domains, i.e. AML model development, factor analysis, econometric analysis and comparative analysis of AML index will provide insights to managers and policy makers about the money laundering scenario in Bangladesh.

Chemical and biological investigations of Delonix regia (Bojer ex Hook.) Raf.

In this study, five compounds, lupeol (1), epilupeol (2), β-sitosterol (3), stigmasterol (4) and p-methoxybenzaldehyde (5) were isolated from the petroleum ether and dichloromethane fractions of a methanolic extract of the stem bark of Delonix regia. Antimicrobial screening of the different extracts (15 μg mm-2) was conducted by the disc diffusion method. The zones of inhibition demonstrated by the petroleum ether, carbon tetrachloride and dichloromethane fractions ranged from 9-14 mm, 11-13 mm and 9-20 mm, respectively, compared to kanamycin standard with the zone of inhibition of 20-25 mm. In brine shrimp lethality bioassay, the carbon tetrachloride soluble materials demonstrated the highest toxicity with LC 50 of 0.83 μg mL-1, while petroleum ether and dichloromethane soluble partitionates of the methanolic extract revealed LC 50 of 14.94 and 3.29 μg mL-1, respectively, in comparison with standard vincristine sulphate with LC 50 of 0.812 μg mL-1. This is the first report on compounds separation from D. regia, their antimicrobial activity and cytotoxicity.

The design of a printed compact planar antenna of asymmetrical structure with ultra wide bandwidth is described and investigated in this paper. The antenna provides more than 114% impedance bandwidth below VSWR 2 (from 3.3 to more than 12 GHz) with a center frequency of 7.65 GHz; thus it covers the bandwidth requirement for portable UWB wireless device applications. The structure of the asymmetric proposed antenna is very simple and composed of a small hexagonal shaped patch with two asymmetrical coplanar ground planes. It occupies an area of only 20 × 24.5 mm2 when printed on one side of an FR4 substrate with a thickness of 1.6 mm.

Oxidative Stress in Painters Exposed to Low Lead Levels

Lead toxicity is a public health problem particularly to the children and to occupationally exposed adults. Evidence is mounting successively regarding the adverse health effects of lead at low levels. This study was undertaken to assess the antioxidant status of lead-exposed residential and commercial painters of Lucknow city in Uttar Pradesh, India.

Thirty-five painters aged 20 to 50 years who had blood lead levels ≤400 μg L-1 were selected for the study from a population of 56 male painters initially screened for blood lead. The control group included an equal number of subjects of the same age group without any occupational exposure to lead.

We studied the association between low lead level exposure and antioxidant status and found that blood lead levels in painters were approximately seven times as high as in controls [(219.2 ± 61.9) μg L-1 vs. (30.6±10.1) μg L-1, respectively]. Among the biomarkers of lead toxicity a significant decrease in the level of delta-aminolevulinic acid dehydratase [(9.13±4.62) UL-1 vs. (39.38±5.05) UL-1] and an increase in the level of zinc protoporphyrin [(187.9±49.8) μg L-1 vs. (26.4±5.5) μg L-1] were observed in painters compared to controls. Among antioxidant enzymes, painters showed a significant decrease in catalase [(56.77±11.11) UL-1 vs. (230.30±42.55) UL-1] and superoxide dismutase [(0.64±0.19) UL-1 vs. (2.68±0.62) UL-1] compared to controls. Lipid peroxidation was monitored by measuring thiobarbituric acid reactive substances (TBARS) that were expressed in terms of malondialdehyde (MDA) equivalents. Concentration of MDA in plasma was higher in painters than in controls [(7.48±1.31) nmol mL-1 vs. (3.08±0.56) nmol mL-1]. Significant changes were also observed in reduced and oxidised glutathione levels. The strong association between blood lead levels and oxidative stress markers in this population suggests that oxidative stress should be considered in the pathogenesis of lead-related diseases among people with low level environmental exposure to lead.

Abstract

Cathinone, the active principle of khat (Catha edulis), stimulates, excites and produces euphoric feelings in khat users. Locomotor and rearing activities, either individual or in groups, of male Swiss albino mice were decreased significantly compared to the control. Motor coordination tests (rotarod, rope climb and grip tests) have shown decreased motor performance in the mice treated with cathinone compared to the control. The elevated plus maze test has shown significant anxiety in the mice compared to the control. Contents of dopamine and its metabolite, homovanillic acid, were increased in the limbic areas compared to the control group. In contrast, contents of 3,4-dihydroxyphenyl acetic acid were depleted significantly and dose dependently compared to the control group in the limbic areas of mice. In conclusion, natural cathinone has depleted motor coordination, accelerated anxiety in mice and altered the contents of dopamine and its metabolites.
