Urban-rural differences in disability-free life expectancy in Bangladesh using the 2010 HIES data
Full text linkBackground
Research on health expectancy has been carried out in Bangladesh but none of it has examined the differences in Disability-Free Life Expectancy (DFLE) between urban and rural setting in context of rapid urbanization of Bangladesh in past decades.
Objectives
The present study aims to estimate DFLE for people of all ages living in urban and rural areas in Bangladesh, and to examine the differences in DFLE between these two areas.
Methods
Data from the Sample Vital Registration System 2010 and the Bangladesh Household Income and Expenditure Survey (HIES) 2010 were used in this study. The Sullivan method was applied to estimate DFLE in Bangladesh.
Results
Higher rates of mortality and disability were observed in rural areas compared to urban areas with few exceptions. Statistically significant differences in DFLE were revealed from birth to age 15 years for both sexes between urban and rural areas. Urban males had a longer life expectancy (LE), longer DFLE and shorter LE with disability both in number and proportion when compared to rural males. Rural females at age 20+ years had a longer LE than urban females but urban females had a longer DFLE and a shorter LE with disability in both number and proportion at all ages than did rural females.
Conclusion
This study demonstrates that there were clear inequalities in LE, DFLE and LE with disability between rural and urban areas of Bangladesh along with age-specific differences as well. These findings may serve as useful and benchmark for intervention and policy implications for reducing the gap in health outcomes

A weighted sample of 4842 individuals who had given a live birth in the three years preceding the surveys. For women who had more than one live birth, only the first live birth was considered in this study.
The outcome variable for this study was whether a Skilled Birth Attendant was present while a woman gave birth to her child
MIMO System Capacity based on Multiple fading channels and varying numbers of antennas including the comparison of MIMO-NOMA and MIMO-OMA
Full text linkMultiput-Input, Multiple-Output (MIMO) systems have greatly improved data speed, connection stability, and spectrum efficiency, revolutionizing wireless communication. In cases where numerous fading channels coexist and the number of antennas at both the transmitter and receiver fluctuates, this paper examined the functionality of MIMO systems. In actual wireless settings, fading channels frequently occur, resulting in time-varying and spatially correlated channel characteristics. In this paper, we used a thorough analysis to investigate the capability of MIMO systems under some difficult circumstances. We considered circumstances with various numbers of antennas, channel correlation, and fading statistics, ranging from Single-Input, Single-Output (SISO) to MIMO setups. We investigated the impact of geographic diversity, Rayleigh, Rician, Nakagami fading models, and correlated fading channels on system performance. The trade-offs between the quantity of antennas, channel correlation, and capacity in MIMO systems are well illustrated by our findings. We presented our evidence in this paper to show that MIMO-NOMA is solely superior to MIMO-OMA in terms of total channel capacity, except in scenarios where communication is limited to one individual, with a power disparity for which MIMO-NOMA can achieve strictly larger rate pairs than MIMO-OMA. This study also explored the outage probability (OP) performance of MIMO-NOMA and MIMO-OMA systems in a massive MIMO communication scenario, including different fading channels. Based on these findings, we demonstrated that MIMO-NOMA can achieve a higher total ergodic capacity than MIMO-OMA
Improvement of Aerodynamic Characteristics of an Airfoil by Static Extended Trailing Edge
No full textThis thesis is submitted to the Department of Mechanical Engineering, Khulna University of Engineering & Technology in partial fulfillment of the requirements for the degree of Master of Science in Mechanical Engineering, April, 2017.Cataloged from PDF Version of Thesis.Includes bibliographical references (pages 44-45).The objective of this work is to study the SETE as an alternative flow control technique for lift enhancement at a small drag penalty in cruise flight. The geometrical quantities, chord distribution and other properties are given in convenient analytical expressions.The experiment was about to enhance the lift of NACA0012 airfoil with static extended trailing edge (SETE). A thin sheet was introduced to the wing trailing edge as a mechanical device without changing the basic configuration of the wing. Calculations were done to compare
the coefficient of lift using static extended trailing edge (SETE) with those of using flap.
The effects of SETE on the wing aerodynamics are mainly due to modifications of the airfoil camber and the flow structure at the trailing edge. The lift enhancement by the SETE is, expectedly, due to the camber effect. It is speculated that the drag penalty of the
SETE is small because it is usually embedded in the wake of the main airfoil. Experimental results are presented, including the lift and drag coefficient of the baseline NACA0012 airfoil model and of model with the SETE and Gurney flaps. The lift enhancement is achieved by the SETE, whereas the drag polar and lift-to-drag ration remains largely unchanged. The zero-lift drag and Oswald’s efficiency are not significantly affected by the SETE. The benefit analysis for the SETE in cruise flight is given in comparison with Gurney flap.Md.

Factors influencing performance of stroke management among nurses in Bangladesh
Full text linkDepartment of NursingABSTRACT Factors Influencing Performance of Stroke Management among Nurses in Bangladesh Md. Shariful Islam Department of Nursing The Graduate School Yonsei University Stroke has become the leading cause of disability and death worldwide. Nurses’ role is pivotal in preventing secondary complications of stroke. Individual and organizational factors greatly influence towards nurses performance of stroke patient management. This study examined level of performance of stroke management and its influencing factors among nurses in Bangladesh. This is a cross-sectional descriptive study. After IRB approval, data were collected from May, 25 to August, 25, 2017 using paper and pencil questionnaire. A total of 226 nurses were recruited from three tertiary level hospitals in Bangladesh. Nurses’ performances were investigated using Demographic Questionnaire (DQ-11), Practice on Stroke Management Questionnaire (PSMQ-10), Stroke Knowledge Questionnaire (SKQ-12), Attitudes on Stroke Mangement Questionnaire (ASMQ-14), Leadership Practice Inventory (LPI-17), Organizational Learning Survey (OLS-25) and Organizational Readiness for Change (ORC-11) related questionnaire. Data were analyzed using descriptive statistics, independent t-test, one way ANOVA, Pearson’s Product-Moment Correlation-Coefficient and Multiple Regression Analysis. Results showed that nurses had moderate level of knowledge (Mean = 3.19, SD = 2.24), attitudes (M = 45. 19, SD = 4.46) and performance (M = 30.29, SD = 6.97). A significant positive correlation found between nurses knowledge and attitudes (r = 0.16, p = 0.05) and between knowledge and performance (r = 0.44, p = 0.000) respectively. However no significant relationship found between attitudes and performance towards stroke management (r = 0.030, p >0.05). Statistical analysis showed that nurses working with ICU ward (β = 7.598, p <0.01), leadership practice ability (β = 0.031, p <0.05), and stroke knowledge (β = 0.864, p <0.001) were major factors affecting nurses’ performance towards stroke management which explained 29.4% of the total variance. In-service stroke education program need to be provided for less experienced nurses who have no previous education on stroke patient maangement to enhance their clinical performance. In addition tertiary level hospital management need to provide more opportunities for their nurses to obtain continuing education on stroke or increase the number of courses available at the institutional level in order to enhance their nurses’ performance towards stroke patient management. ________________________________________________________________________open박

No full textWe synthesized mixed ? and ?-Fe2O3 nanoparticles and investigated their toxic effects against HeLa cells under induced AC (alternating current) magnetic-fields and photoexcited conditions at room temperature. The findings revealed that the cellkilling percentage was increased with increasing dose for all types of treatments. Finally, 99% cancer cells were destructed at 1.2 mL dose when exposed to combined AC magnetic-field and photoexcited conditions (T3) whereas 89 and 83 % of HeLa cells were killed under only AC magnetic-field induced (T1) or only photoexcited (T2) condition at the same dose
Development of electric stove for smart use of Solar Photovoltaic energy with national grid
No full textThis thesis report is submitted in partial fulfillment of the requirements for the degree of Bachelor of Science in Electrical and Electronic Engineering, 2013.Cataloged from PDF version of thesis report.Includes bibliographical references (page 70-72).Saving energy is now one of the major concerns for the researchers. Still a lot of fossil fuels are being consumed directly or indirectly just for cooking and hence affecting the global environment. With the rapid increase in demand of energy for cooking with proportion to population increase, it will not take much time to finish all the resources that are available now. According to the thesis, energy for cooking is mostly supplied from solar photovoltaic panels in alliance with national grid line. The major contribution of this project will be the invention of re-designing existing stove coil. The national grid will be in action only when, panel and battery are not giving sufficient power to the load. An Electric Charge Controller will ensure safety of the system and store charge in the Battery. The research given in this thesis aims at analyzing the time requirement for cooking same foods in comparison with the gas or normal electric stove. To show the effectiveness as compared to natural gas or electric stove, the thesis contains a huge statistical data, taken for a number of times. Modification of the stove for providing variable energy to cook different food is the future work of the thesis.Md. Shariful IslamMd. Sabbir Bin AzadHumayra Fakir RongonB.
