Contributions of Women’s Participation in the Local Government of Bangladesh  [PDF]
Md. Mizanur Rahman
Sociology Mind (SM) , 2015, DOI: 10.4236/sm.2015.53018
Abstract: Union Parishad (UP) as a unit of rural local government of Bangladesh has a history of 145 years but women’s representation was ensured only 2 decades ago. The paper is based on the argument that within the span of 2 decades, despite encountering huge challenges some women leaders (WLs) might have performed their role with their constrained participation in the UP. Against such a context, the paper is aimed at unraveling the research question: How did WLs perform in the UP amidst their challenges and constrained participation? The paper is based on hermeneutic phenomenological approach which was supported by case study, content analysis and observation methods. The findings of the paper revealed that having ensured their limited participation in the UP some women leaders were able to promote transparency and accountability, establish social justice and provide community services in the rural society.

Food and Nutrition Sciences (FNS) , 2013, DOI: 10.4236/fns.2013.49A2001
Abstract:

Calcium hypochlorite commercially known as bleaching powder is used as a bleaching agent in shrimp processing industries in many countries and known to effect biochemical alteration in shrimp muscle. Studies were, therefore, undertaken to determine their effect in different concentrations viz., 10, 20, 30, 40 and 50 ppm with different time intervals on the quality of head-on, headless shell-on and peeled giant freshwater prawn (Macrobrachium rosenbergii) by determining biochemical and organoleptic aspects. Myofibrillar protein solubility of fresh head-on, headless shell-on and peeled samples were 90.5%, 90% and 88%, respectively indicating a gradual decrease in protein solubility with increasing concentration of bleaching powder. Decrease in protein solubility was also higher in samples kept at longer duration in different concentration of bleaching powder. At a given concentration of 50 ppm for 30 min treatment, the loss of myofibrillar protein was higher (26.14%) in peeled samples than those of head-on and headless shell-on samples (20.44% and 21.11%). Shelf life of bleaching powder treated prawn samples was found to be reduced to 4 - 5 days in iced condition compared to 6 - 7 days for control samples. Peeled samples were also found to be more susceptible to bleaching powder than that of head-on and headless shell-on samples.

Md. Mizanur Rahman, Ayub Ali, Md. Abdullah Yusuf, Md. Zamil Zaidur Rahim, Md. Mahfuzur Rahman, Zahir-ul Islam
Journal of Tuberculosis Research (JTR) , 2017, DOI: 10.4236/jtr.2017.52015
Abstract: Background: Clinical presentation of intestinal tuberculosis is varied. It is also essential to know the clinical and demographic characteristics of incidentally detected intestinal tuberculosis patient. Objective: The purpose of the present study was to find out the clinic-demographic characteristics of intestinal tuberculosis in clinically and preoperatively unsuspected laparotomies. Methodology: This cross-sectional study was carried out in the Department of Surgery at Dhaka Medical College Hospital, Dhaka from March 2002 to March 2004 for a period of two (2) years. All the patients underwent laparotomy presented without any suspicion of pulmonary or intestinal tuberculosis were included as study population. Patients who were without the history of cough, haemoptysis, antitubercular drug therapy were included. Per operative suspicion was raised due to enlarged lymph nodes in mesentery, omental masses, ileocaecal masses, suspicious growth in ileum, omental thickening, perforation suspected by tuberculosis. Biopsy was taken from suspicious lesions. Histopathology was confirmed the tubercular lesion. Results: A total number of 300 patients under laparotomy were recruited for this study of which 38 positive cases were found in the study with a percentage of 12.7%. Maximum affected age group was 21 to 30 years which was 16 (42%) cases. Male was predominant to female which was 28 (73.7%) cases and 10 (26.3%) cases respectively. Low socioeconomic people are affected more (76.3%). Most common presentation in positive cases was acute and sub-acute intestinal obstruction 20 (52.6%) followed by intestinal perforation (26.31%). Conclusion: In conclusion young age male patient is the most commonly affected intestinal tuberculosis which is frequently presented with sub-acute intestinal obstruction among the preoperatively unsuspected laparotomy patients.
Secure Data Exchange in P2P Data Sharing Systems in eHealth Perspective
Mehedi Masud,Sk. Md. Mizanur Rahman
International Journal of Computer Science Issues , 2012,
Abstract: In P2P data sharing systems (P2PDSS) peers share data in a pair-wise fashion. Data are shared on-the-fly by establishing temporary data exchange session for user queries. Generally, the communication link between peers is unsecured while exchanging data. In P2P eHealth data sharing scenarios, peers may need to exchange highly confidential data among them. Hence, there are some security threats that need to be considered (e.g. data might be trapped and disclosed by the intruders). In a P2PDSS, we cannot assume any third party security infrastructure (e.g. PKI) to protect confidential data. Considering the need of secure data exchange in P2PDSS, in this paper we propose a secure data exchange model. The model is based on pairing-based cryptography and the data sharing policy between peers. Applying the model, peers compute secret session keys dynamically by computing pairing on elliptic curve, based on the data sharing policies while exchanging data. The proposed protocol is robust against the man-in-the middle attack, the masquerade attack and the replay attack.

Mohammad Mizanur Rahman, Mohammad Abdur R. Akond, Mohammad Khairul Basher, Md. Quamrul Huda
World Journal of Nuclear Science and Technology (WJNST) , 2014, DOI: 10.4236/wjnst.2014.42013
Abstract:

The COOLOD-N2 and PARET computer codes were used for a steady-state thermal hydraulic and safety analysis of the 3 MW TRIGA Mark-II research reactor located at Atomic Energy Research Establishment (AERE), Savar, Dhaka, Bangladesh. The objective of the present study is to ensure that all important safety related thermal hydraulic parameters uphold margins far below the safety limits by steady-state calculations at full power. We, therefore, have calculated the hot channel fuel centreline temperature, fuel surface temperature, cladding surface temperature, the departure from nucleate boiling (DNB) heat flux and DNB ratio, axial fuel centreline temperature and compared. The comparison indicates that the calculated values are in satisfactory agreement between the codes. The data obtained in this investigation are largely far to compromise safety of the reactor. The results can also be used to upgrade the current core configuration of the TRIGA reactor.

Design of a High Performance Reversible Multiplier
Md.Belayet Ali,Hosna Ara Rahman,Md. Mizanur Rahman
International Journal of Computer Science Issues , 2011,
Abstract: Reversible logic circuits are increasingly used in power minimization having applications such as low power CMOS design, optical information processing, DNA computing, bioinformatics, quantum computing and nanotechnology. The problem of minimizing the number of garbage outputs is an important issue in reversible logic design. In this paper we propose a new 44 universal reversible logic gate. The proposed reversible gate can be used to synthesize any given Boolean functions. The proposed reversible gate also can be used as a full adder circuit. In this paper we have used Peres gate and the proposed Modified HNG (MHNG) gate to construct the reversible fault tolerant multiplier circuit. We show that the proposed 44 reversible multiplier circuit has lower hardware complexity and it is much better and optimized in terms of number of reversible gates and number of garbage outputs with compared to the existing counterparts.

Agricultural Sciences (AS) , 2017, DOI: 10.4236/as.2017.86037
Abstract: To know the position, problems and suggestion of harvest mechanization of rice, the study conducted in 21 upzillas under seven regions (Dhaka, Mymensingh, Sylhet, Comilla, Bogra, Rajshahi and Rangpur) based on different agro-climatic condition and cropping intensity and 126 farmers participated in the interview. For collecting data, a structured questionnaire was used and statistical analysis of the collected data was carried out. In study area, the average cultivable area was 225 to 1239 decimal (1 decimal = 40 m2) and 97.60% farmer reaping by sickle and only 0.80% used combine harvester. Cut paddy transported by head (13.49%), shoulders (12.7%) or both of them of 11.11% farmer and 44.44% of farmers used small truck or field threshed. Threshing was mainly done using (49.21%) closed drum thresher and open drum thresher (26.20%), likewise 1 of 126 farmer use head-feed combine harvester. The study area, most farmers (37.3%) used kula for the cleaning of rice, but only 8.74% of farmers used winnower. In considerable amount, 80.95% of farmers had machinery, while the remaining (19.05%) did not have machines. Farmers agreed that harvesting was a labor-intensive method (35.71%) and time consuming (28.57%). Transporting of harvested paddy was dangerous and painful for head, shoulder, hand, waist, backbone, leg, etc. With mechanization and the introduction of machinery, 40.48% of farmers identified the main ceiling as the price of the machine and information/lack of credit system (21.43%). In survey area, most farmers (36.51%) identified the vital advantage of mechanized harvesting as lower labor requirement, while 21.43% of farmers said that a lower loss of rice. All farmers who participated in the interview expressed their need for machinery and mentioned agricultural credit with easy terms and conditions, subsidy for buying machinery and the ensuring of a fair market price for their rice.

Open Journal of Soil Science (OJSS) , 2017, DOI: 10.4236/ojss.2017.75007
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.

Abstract: Background: The word asphyxia is now commonly used to describe a range of conditions for which the lack of oxygen whether it is partial (hypoxia) or complete (anoxia) is considered to be the cause. The cardinal signs of asphyxia are cyanosis, congestion and petechial haemorrhage.Objective: To investigate the causes and manner of asphyxial death.Materials and Methods: It was a retrospective study conducted in the department of Forensic Medicine, Dinajpur Medical College, Dinajpur during July 2004 to June 2006. A total of 96 cases were examined and recorded. These cases were brought to the morgue of Dinajpur Medical College from 13 different police stations and 1 railway GRP station of Dinajpur district. The data were collected from the autopsy reports (preserved third copy) with permission of the concerned autopsy surgeons.Results: 88.55% of asphyxia deaths were due to hanging, 6.25% due to strangulation and 5.20% were due to suffocation.Conclusion: Most of the asphyxial deaths are due to hanging.
Rethinking the Approaches to Women Empowerment: Bangladesh Perspective
Ismail Hossain,Tahmina Akhtar,Md. Mizanur Rahman,Md. Taj Uddin
Journal of Applied Sciences , 2006,
Abstract: This research re-examines the approaches to women empowerment highlighting their weakness in the existing field of application. The three approaches of women empowerment-integrated development approach, economic development approach and consciousness raising and organizing approach are not fulfilling the expectation of women as the whole process of decision making is done by the men, whereas women participation is indispensable for equal, just and gender unbiased society. The findings of the article indicate that women are ignored in decision making process because male attitude towards female is not positive, which causes gender discrimination in the society leading the existing approaches of women empowerment to rethinking for a new approach, which may fulfill the goal of women empowerment in the new millennium. This study comes to a conclusion suggesting the new approach for the empowerment of women in this challenging era of globalized world.
