Abstract: Medium-term changes in the labile nutrient pool of microbial biomass carbon (MBC) and nitrogen (MBN) resulting from organic manure application in rice (Oryza sativa L.)-based triple cropping systems have been poorly studied. Therefore, the effects of organic materials on the soil physico-chemical properties and microbial biomass in rice fields were investigated at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Bangladesh, from April 2010 to December 2012. Five treatments (control, cow dung, poultry manure, rice straw, and chemical fertilizer) were laid out in a randomized complete block design with four replications. The organic residues (2 t C ha-1) were applied 7 days before transplanting and were combined with inorganic fertilizers, following integrated plant nutrition systems. This paper presents the results from the last of the five consecutive rice growing seasons. All of the organic residues increased the pH, and organic C, N, P, and K contents of the soil. However, poultry manure was more efficient in increasing soil fertility than cow dung and rice straw, resulting in a significant increase in P from 22 mg·kg-1 to 63 mg·kg-1 at crop harvest. All of the organic residues also increased the soil water holding capacity and decreased bulk density. Furthermore, poultry manure resulted in significantly higher microbial biomass C (432 mg·kg-1; P < 0.05) and N (31.60 mg·kg-1; P < 0.05) levels in the soil at crop harvest, followed by cow dung and rice straw. These findings indicate that the regular application of organic residues and manures will help to enhance soil fertility and production sustainability.
Determinants of Maternal Health Care Utilization in Bangladesh

Research Journal of Applied Sciences , 2012,
Abstract: Utilization of maternal health care services and maternal health seeking behaviors is a complex phenomenon in Bangladesh due to various factors. It is found that a complex set of relationship exists among the various socioeconomic, cultural, behavioral and demographic events, which affect the utilization of maternity care in Bangladesh, which can only provide us a preliminary idea of how important each variable is by itself. Result shows that maternal education, mother s age at birth, present place of residence, access to mass media and NGO and wealth quintile significantly increase the utilization rates for antenatal care, delivery care and postnatal care. Findings need to be scientifically utilized in developing suitable programs addressing the case of maternal health care services in the developing countries as well as in Bangladesh.
Levels and Differentials of Maternal Health Care Utilization in Bangladesh
K.M. Mustafizur Rahman,Prosannajid Sarkar
Research Journal of Medical Sciences , 2012,
Abstract: Maternal health situation appears to be very poor in Bangladesh. Utilization of basic health services in Bangladesh has remained poor even though, there has been increasing public and private expenditure on the provision of advanced health care. The low utilization seems to be due to low levels of household income, high illiteracy and ignorance and a host of traditional factors. On the other hand, despite substantial public investments in health infrastructure the supply of such services continues to be inadequate and of poor quality. Over the last several decades maternal health care in Bangladesh has improved, but that condition is not satisfactory stage considerably compared to many other developing nations. However, for cultural and economic reasons, puerperal maternal health care has not received much attention when compared to the care provided during pregnancy. This may be attributed to the fact that although, the pregnant female is cared for, the attention is focused on the child, which the mother carries, rather than the mother. Although, the overall situations of maternal health care services in Bangladesh are increased after independent, but these are not better picture to reduce maternal mortality to reach the target of millennium development goal.
Determinants of Infant and Child Mortality in Bangladesh

Pakistan Journal of Social Sciences , 2012,
Abstract: Infant and child mortality rates reflect a country s level of socio-economic development and quality of life and are used for monitoring and evaluating population and health programs and policies. This study examines the mortality of children under five using information from women s birth histories pertaining to children born during the 10 years period before the survey by major divisions in Bangladesh, using data from the 1999-2000 Bangladesh Demographic and Health Survey (BDHS). Specifically, information is provided on levels, trends and differentials in neonatal, post-neonatal, infant and child mortality and assessing the effects of socio-economic, demographic and mother s health-care characteristics on infant and child mortality. Mortality estimates are desegregated by urban-rural residence, division, mother s education and antenatal care received and by selected demographic characteristics to identify segments of the population requiring special attention. This will help policy makers to formulate better policies in order to fight the current situation.
Situation of Maternal Health Care Services in Bangladesh
Prosannajid Sarkar,K.M. Mustafizur Rahman
The Social Sciences , 2013,
Abstract: Improvement of the reproductive health status of women in the third world is being considered as one of the most important goals of human and social development. Bangladesh has achieved health gains over the last decade of the 20th century. However, equivalent program has not been realized in the area of maternal health. Despite the presence of an impressive establishment of the health infrastructure in the country to date the maternal health situation remains poor. Even through, the most maternal deaths are avoidable if adequate preventive observed are taken. Increasing the proportion of maternal health care services is being advocated as an important step in preventing maternal death.
Trends of Population Ageing from 1950-2050: A Comparative Study Between Bangladesh and World
K.M. Mustafizur Rahman,Muntasir Ibn Mohsin,Ismail Tareque
Pakistan Journal of Social Sciences , 2012,
Abstract: Population ageing-the process by which older individuals become a proportionally larger share of the total population-was one of the most distinctive demographic events of the 20th century. It will surely remain important through out the 21st century. Initially experienced by more developed countries, the process has recently become apparent in much of developing world like Bangladesh as well. Since, the older population is growing at a considerably faster rate and the life expectancies are increased with the advancement of time, the elderly should be considered not as a burden to the society but their valuable experience should be utilized fruitfully and it should be the responsibility of not only society and the government but also the people. The state has not yet develops the mechanisms to respond to the emerging ageing challenge.
Effects of Egg Size on Fertilization, Fecundity and Offspring Performance: a Comparative Study Between Two Sibling Species of Tropical Sea Urchins (Genus Echinometra)
M. Aminur Rahman,Tsuyoshi Uehara,S. Mustafizur Rahman
Pakistan Journal of Biological Sciences , 2002,
Abstract: The effects of egg size on fertilization, fecundity, embryonic and larval development as well as offspring performance were compared between two closely related species of tropical sea urchins, Echinometra sp. A (Ea) and Echinometra sp. C (Ec) through laboratory experiments. Ec had significantly larger gametes in terms of egg diameter, egg volume and sperm head length and produced significantly larger but fewer eggs with higher fertilization rate than Ea. Developmental time from fertilization to the formation of echinus rudiment, just prior to the metamorphic competence of Ea were significantly longer than Ec, suggesting that increased allocation to energy reserves in larger Ec eggs reduced the development period as compared with the small Ea eggs. Consequently, smaller eggs of Ea produced smaller larvae than Ec throughout the larval period, due to the small amount of maternal investment as stored nutrients. As Ea and Ec have diverged from their ancestral species, the differences of the above traits related to egg sizes transcended species differences between Ea and Ec.

Md. Mustafizur Rahman,Md. Elias,M. A. Alim
Journal of Engineering and Applied Sciences , 2009,
Abstract: In this paper, a study of mixed convection flow inside a rectangular ventilated cavity in the presence of a heat conducting square cylinder at the center has been carried out. An external fluid flow enters the cavity through an opening in the left vertical wall and exits from another opening in the right vertical wall. The governing equations are transformed into non-dimensional form and the resulting partial differential equations are solved by the finite element method. Results are presented in the form of average Nusselt number of the heated wall, average temperature of the fluid in the cavity and temperature at the cylinder center for the range of Richardson number and cavity aspect ratio. The streamlines and isothermal lines are also presented.

Asian Journal of Plant Sciences , 2006,
Abstract: The incidence of leaf spot of mustard (cv. BARI sharisha 13) grown in different orientations and distances under around twelve years old Akashmoni (Acacia auriculiformis) tree was studied in the field laboratory of the Department of Agroforestry, BAU, Mymensingh during 2004-05. The assessment result showed that the disease incidence was higher near the tree base in every side (1 m from the tree base) and higher in North side in all distances at different date of sowing. The lowest disease incidences were found in South orientations 3 m from the tree base and highest in North 1 m from the tree base. The siliqua infection significantly influenced on crop yield. The highest seed yield was observed in South orientation 3 m from the tree base and lowest in North 1 m from the tree base plot. The distance and orientation showed marked effect in disease development at different date after sowing. In open field condition (control) disease incidence also affect on yield and statistically different from tree-crop combination.

Md. Asikur Rahman,Md. Mustafizur Rahman,Md. Mustafa Kamal Bhuiyan,S. M. Shahnewaz
International Journal of Data Mining & Knowledge Management Process , 2012,
Abstract: Clustering analysis is an important function of data mining. There are various clustering methods in DataMining. Based on these methods various clustering algorithms are developed. Ant-clustering algorithm isone of such approaches that perform cluster analysis based on “Swarm Intelligence’. Existing antclusteringalgorithm uses two user defined parameters to calculate the picking-up probability and droppingprobability those are used to form the cluster. But, use of user defined parameters may lead to form aninaccurate cluster. It is difficult to anticipate about the value of the user defined parameters in advance toform the cluster because of the diversified characteristics of the dataset. In this paper, we have analyzedthe existing ant-clustering algorithm and then numerical analysis method of linear equation is proposedbased on the characteristics of the dataset that does not need any user defined parameters to form theclusters. Results of numerical experiments on synthetic datasets demonstrate the effectiveness of theproposed method.
