Measuring the Association of Overweight and Obesity with Human Disease and Other Factors in Bangladesh

Open Journal of Statistics 2020年第3期10卷 402-411页

作者： md. Roshidul Islam md. Anamul haque Department of Statistics Begum Rokeya University Rangpur Bangladesh

Overweight and obesity in people are epidemic in North America and internationally. In the United States, the number of overweight children and adolescents has doubled in the last two to three decades, and similar increasing rates are being observed worldwide, including developing countries as Bangladesh where an increase in Westernization of behavioral and dietary lifestyles is evident. Human diseases associated with overweight and obesity are similar in children as in the adult population. The main purpose of this study was to examine the association between overweight and obesity with human disease and other factors in Bangladesh. We have attempted to estimate the relationship between associated variables by using the Pearson Chi-Square test. It also showed how important an individual variable is by itself. The study also employed a statistical technique namely, logistic regression analysis which has been used to find out the association of overweight and obesity with human disease and other factors. We have seen that 16.96% people are overweight

利用三维地震和测井资料对Maui气田晚白垩世—上新世的沉积层序建立构造模型，结合地质统计学方法预测Taranaki盆地的构造力学特征。通过构造模型识别出受断裂影响的3期构造运动：晚白垩世—古新世裂谷期、晚始新世—中新世挤压性断裂期、上新世一更新世构造分化期（Maui气田南部挤压性断裂、Maui气田北部正断层活动）。各期构造运动形成不同的构造样式，早渐新世以前具有轻微走滑特征的正断层较发育，断层倾角大（40°-70°），北部地层倾角（10°-15°）低于南部（15°-20°）；中渐新世一晚中新世发育低角度逆断层（20°-40°），表明这一时期构造整体受到挤压性应力作用；中渐新世—上新世地层出现构造反转，表明这一时期构造应力为先挤压后拉张。

International Journal of Sediment Research 2007年第1期22卷 49-59页

To mitigate scour around bridge piers, sacrificial piles are economic method where natural processes are involved. The arrangement should be such that scoured materials from the sacrificial piles should have enough volume to fill the scour hole created upstream of the pier in such a way that sediments are trapped inside the scour hole. This concept differs from earlier study made with sacrificial piles that mainly deals to reduce the strength of horseshoe vortex. To determine the effect of sacrificial piles for scour mitigation, alternative arrangements of piles were tested in front of a rectangular pier under clear-water condition and found that when the group of piles is placed at a distance of twice the projected width of the pier, for which percentage of blockage of the pier width is 60%, the scour volume can be reduced upto 61% while the maximum scour depth can be reduced upto 50%.

Ion-Acoustic Higher Order Non-Linear Structures in Quantum Dusty Plasma

引用

Journal of Modern Physics 2013年第11期4卷 1530-1535页

作者： md Manir Hossain Monirul Hasan md A saduzzaman md Mahfuzul haque Department of Electrical and Electronic Engineering Bangladesh University of Business and Technology Dhaka Bangladesh Institute of Natural Science United International University Dhaka Bangladesh

The prominent features of higher order nonlinear ion-acoustic waves involving quantum corrections in an unmagnetized quantum dusty plasma are revisited with the theoretical framework of Hossain et al. [1]. The fluid model is demonstrated here by its constituent inertial ions, Fermi electrons with quantum effect, and immovable dust grain with negative charge. We have used the ideology of Gardner equation. The well-known RPM method is employed to derive the equation. Indeed, the basic features of quantum dust ion-acoustic Gardner solitons (GSs) are pronounced here. GSs are shown to exist for the value of dust to ion ratio around 2/3 which is valid for space plasma [2], and are different from those of K-dV (Korteweg-de Vries) solitons, which do not exist for the value around 2/3. The implications of our results are suitable for cosmological and astrophysical environments.

Effect of Variety and Growth Regulator Concentration on Success of Air Layering in Plum

引用

Agricultural Sciences 2022年第1期13卷 65-73页

作者： Shailendra Nath Mozumder md. Iqbal haque md. Masudul haque Dristi Sarkar Muhammad Shahiduzzaman Regional Spices Research Center Bangladesh Agricultural Research Institute Gazipur Bangladesh Bangladesh Maize and Wheat Research Institute Nashipur Bangladesh

The experiment was conducted at the Regional Spices Research Center, BARI, Gazipur during June 2016 to October 2017 to evaluate the effect of genotype and growth regulator (IBA) on the success and performance of plum air layering. Air layering was done on two plum varieties (BARI Alubokhara-1 and PD Gaz 004) using seven levels of IBA concentration (viz. 0, 1000, 2000, 3000, 4000, 5000 and 6000 ppm) under a complete randomized (factorial) design (CRD). Significant variation was observed on rooting, establishment and death of layers due to variety and IBA concentrations except rooting and separation time. The un-fruiting line PD Gaz 004 showed outstanding performance in rooting and survivability of layers over BARI Alubokhara-1. Poor rooting and lower establishment caused very high mortality of layers in BARI Alubokhara-1. Rooting and survivability, number of roots, length of roots and leaf production increased with the increasing levels of IBA concentration up to 5000 ppm. The maximum (10 out of 10) rooting success of layer with 65.83% and 59.17% establishment from PD Gaz004 was obtained when 3000 and 4000 ppm IBA was used, respectively. In BARI Alubokhara-1, the highest rooting success (3.08), establishment rate (29.42%), number of root (4.28/layer) and root length (5.08 cm) were recorded with 4000 ppm IBA concentration.

Indium tin oxide(ITO) thin film was deposited on glass substrate by means of vacuum evaporation technique and annealed at 200 ℃, 300℃ and 400 ℃ in air for 1 h. The characterization and properties of the deposited film samples were analyzed by X-ray diffraction(XRD), scanning electron microscopy(SEM), and UV-VIS-NIR spectroscopy techniques. From the XRD patterns, it was found that the deposited thin film was of crystalline at an annealing temperature of 400℃. The crystalline phase was indexed as cubic structure with lattice constant and crystallite size of 0.511 nm and 40 nm, respectively. The SEM images showed that the films exhibited uniform surface morphology with well-defined spherical grains. The optical transmittance of ITO thin film annealed at 400 ℃ was improved from 44% to 84% in the wavelength range from 250 nm to 2 100 nm and an optical band gap was measured as 3.86 e V. Hall effect measurement was used to measure the resistivity and conductivity of the prepared film.

Morphological and Molecular Characterizations of Country Bean (Lablab purpureus L.) Genotypes for Drought Tolerance

引用

American Journal of Plant Sciences 2024年第11期15卷 1069-1090页

作者： Nazifa Tasnia Ruan Binte haque Mirza Mofazzal Islam md. Ashraful haque Department of Genetics and Plant Breeding Bangladesh Agricultural University Mymensingh Bangladesh Department of Biochemistry and Molecular Biology Jahangirnagar University Savar Dhaka Bangladesh Plant Breeding Division Bangladesh Institute of Nuclear Agriculture (BINA) Mymensingh Bangladesh

Country bean, Lablab purpureus (L.) is considered one of the most important leguminous crops, but their cultivation under drought stress condition encounters challenges. In this study, an experiment has been conducted among 30 genotypes under drought condition to explore morphological diversity of qualitative and quantitative, biochemical, molecular analysis. The study identified significant variations in eight traits among the genotypes examined, with phenotypic variance exceeding genotypic variance, indicating both genetic and environmental influences. High heritability and genetic advance were observed in primary, secondary, and tertiary branch lengths, suggesting these traits are likely controlled by additive gene effects, making them effective targets for selection. Principal component analysis identified three components that made a substantial contribution, accounting for approximately 73.06% of the overall quantitative variations. Among the quantitative traits, the highest coefficient of variation (CV%) has been found in number of flowers (55.05%). While number of primary branches, primary branch length, number of secondary branches, secondary branch length, number of tertiary branches, tertiary branch length has individually more than 20% of CV%. The genotypes have been grouped into three clusters based on quantitative traits. Analysis of protein reveals that the genotypes of DS28 and DS29 have higher protein content than other genotypes. Dehydrogenase responsive genotypes have been found on DS28 and DS29 from the molecular analysis. The results suggest that the genotypes DS28 and DS29 could contribute as genetic resource of high protein content and DREB responsive, and the eight quantitative traits of 30 genotypes could be used for further breeding programme.
