Traditional Profession and Livelihood: A Study on Sweeper Community

The study aims to find the trend of traditional profession, livelihood situation of sweeper community and causes behind the living in between poverty in Bangladesh. Survey and focus group discussion (FGD) were taken as method. The findings show that all household of the sweeper are being deprived from socio economic advantages, comparatively with general community. Most of the sweeper's households are burden by excess expenditure over income. They are depending on loan from informal sector. Over the generation, they have not been changing their profession radically due to several causes. Government and non- government sector should take more initiative that ensures sweeper communities access to same rights and services enjoyed by mainstream society. Immediate action is necessary to uplift and reform their livelihood and professio

DOMESTIC VIOLENCE AGAINST WOMEN: A HISTORIC AND SOCIO-CULTURAL REALITY IN BANGLADESH

Domestic violence against women is prevalent throughout the world in different forms even in this twenty first century. Though the view towards domestic violence varies across the countries the World Bank has already spotted it as a global epidemic. Domestic violence, whether in urban or rural areas, puts women community at vulnerable position as it causes both physical and psychological grievances. Several forms of domestic violence including physical, psychological, sexual and economical violence have been illustrated by different organizations worldwide. In Bangladesh, the patriarchal capitalism puts women in such a position that they always remain subservient under mail domination and in many cases this is reflected through violence against them. This was criminalized in Bangladesh in 2010. But the laws are not enough alone to protect the women from sufferings. Strategies should be taken to raise the awareness among the general population along with effective implementation of the law. This paper depicts an overview on domestic violence against women from socio-cultural and legal perspective emphasizing especially over the situation in Bangladesh

Measuring Climatic and Hydrological Effects on Cash Crop Production and Production Forecasting in Bangladesh Using ARIMAX Model

The objective of this study is to measure the climatic and hydrological effects on cash crop productions in Bangladesh using Box-Jenkins Auto-Regressive Integrated Moving Average (ARIMA) model with external regressor variables, that is, ARIMAX model. At the same time, forecasting cash crop production using the same model under consideration of the climatic and hydrological effects. It is not very easy to measure the climatic and hydrological effects on different types of agricultural crop production in as usual regression model because of time sequence dataset. Because of time sequence data, Box-Jenkins ARIMAX model is used in this study to measure the climatic and hydrological effects on different major cash crop production in Bangladesh, where climatic and hydrological variables are used as external regressor variable. This is the new study to measure climatic and hydrological effects on crop production using ARIMAX model. The best fitted ARIMAX model for Sugarcane, Tea, Tobacco and Cotton production are ARIMAX(0,1,1), ARIMAX(0,1,1), ARIMAX(0,1,1), ARIMAX(1,1,0) respectively. Keywords: Climate, Hydrology, Cash Crop, ARIMAX Model, Forecasting, Bangladesh.

Design of Low Power MAX Operator for Multi-valued Logic System

AbstractA voltage-mode three transistor based MAX circuit for implementation of multi-valued logic (MVL) system is proposed in this paper. The proposed MAX operates at very low power consumption ranging in micro watts. To evaluate MAX performance, a NOR gate realization is done and compared to standard CMOS NOR gate. The HSpice simulation result confirms the MAX based NOR gate to operate with minimal delay at low power level. The simulations have been performed on 180nm technology

A Legal Approach to Prevent Road Accident in Bangladesh: Drawbacks and Recommendations

As a serious man-made epidemic and distressing occurrence in the community is known road accident, which is affected though personally but afterwards harsh impact goes to social and economies field Major concern is road traffic accidents and picture of injuries have now emerged as outrageously or tremendously. The alarming rate of dreadful road traffic accidents may have increased due to certain reasons: lack of political concern, lack of accountability of the principal category of law abiding citizens, incompetent drivers, inadequate punishment etc. In a country with limited resources, like Bangladesh it considered as hinders of all development and caused worst impact on GDP. This study focused on observing the behavior of law abiding pedestrians and drivers; and try to relation under the obligation of Law as the sole identity of citizenship. Also, the road safety situation how developed and some contemporary issues and priorities are briefly discus in this dissertation. Keywords: Safety, Transport, Traffic, Accident, Injure, Problem, Punishment. DOI: 10.7176/JLPG/81-07

Histopathological and environmental effects of the insecticide, sumithion on the fish, tilapia (Oreochromis niloticus) in pond condition

The present research work was conducted to evaluate the effects of organophosphate insecticide, sumithion on water quality parameters, density of plankton population and histological changes of kidney and liver of the fish, tilapia (Oreochromis niloticus) in aquaculture ponds during July to December 2016. The experiment was conducted with four treatments, each with two replications. Treatment T0 was used as control (no sumithion) and other three treatments with 0.025 ppm (T1), 0.050 ppm (T2) and 0.100 ppm sumithion (T3). The water quality parameters such as dissolved oxygen, free carbon dioxide, pH, total alkalinity, NO3-N and PO4-P fluctuated significantly under four treatments during the experimental period but they were not affected by sumithion application. The phytoplankton densities (×105 cells L-1) was not affected by sumithion. Six genera of phytoplankton populations were found in the experimental ponds. On the other hand, zooplankton population densities (×103 cells L-1) were significantly reduced with increasing doses of sumithion (T2 and T3) in comparison with that of control (T0). Histological changes of kidney were observed after application of sumithion. The renal corpuscle, collecting duct, hematopoietic cells and other cells of the kidney in control (T0) were normal and systematically arranged. Abnormal collecting duct, Intra-cellular space, degenerated renal corpuscle, irregular shaped blood vessel, ruptured membrane large vacuole and necrosis were found in T1, T2 and T3.Normal structure of liver cells such as hepato-pancreas, hepatic cell and blood vessel were observed in T0 (control). Sumithion exposed liver sections showed rupturedhepato-pancreas, necrosis, hemorrhage, intra-cellular space, degenerated hepatopancreas and large vacuole were found in T1, T2 and T3. Therefore, it reveals that sumithion has adverse effects on kidney and liver of the test fish. So, sumithion should not be used indiscriminately in agriculture and aquaculture practices. It may be concluded from the research finding that dissolved oxygen, free carbon dioxide, pH, total alkalinity, PO4-P, NO3-N, phytoplankton and zooplankton values under treatment, T0, are significantly different from treatments T1, T2, and T3 in most cases.

Pyrolysis of municipal green waste: a modelling, simulation and experimental analysis

Pyrolysis is the thermo-chemical conversion of carbonaceous feedstock in the absence of oxygen to produce bio-fuel (bio-oil, bio-char and syn-gas). Bio-fuel production from municipal green waste (MGW) through the pyrolysis process has attracted considerable attention recently in the renewable energy sector because it can reduce greenhouse gas emissions and contribute to energy security. This study analyses properties of MGW feedstock available in Rockhampton city of Central Queensland, Australia, and presents an experimental investigation of producing bio-fuel from that MGW through the pyrolysis process using a short sealed rotary furnace. It was found from the experiment that about 19.97% bio-oil, 40.83% bio-char and 29.77% syn-gas can be produced from the MGW. Then, a four-stage steady state simulation model is developed for pyrolysis process performance simulation using Aspen Plus software. In the first stage, the moisture content of the MGW feed is reduced. In the second stage, the MGW is decomposed according to its elemental constituents. In the third stage, condensate material is separated and, finally, the pyrolysis reactions are modelled using the Gibbs free energy minimisation approach. The MGW\u27s ultimate and proximate analysis data were used in the Aspen Plus simulation as input parameters. The model is validated with experimentally measured data. A good agreement between simulation and experimental results was found. More specifically, the variation of modelling and experimental elemental compositions of the MGW was found to be 7.3% for carbon, 15.82% for hydrogen, 7.04% for nitrogen and 5.56% for sulphur. The validated model is used to optimise the biofuel production from the MGW as a function of operating variables such as temperature, moisture content, particle size and process heat air-fuel ratio. The modelling and optimisation results are presented, analysed and discussed
