Pretreatment of ITO electrode and its physiochemical properties: Towards device fabrication

Abstract: The aim of this review is to discuss the effect of different pretreatments on the physical and chemical properties of Indium Tin Oxide (ITO) thin films, as well as device performance towards sensor applications. The emphasis is on the surface science studies of ITO thin films before and after treatment in order to provide connecting points between surface properties with a broader field of materials science of ITO. The morphology of a monolayer deposited on ITO directly affects the surface properties of prepared ITO films. Thus, it is a topic of interest to study the influence pretreatment on the surface morphology of ITO films on device fabrication and applications as a device platform.

Prevalence and Risk Factors of Obesity and Hypertension Among University Students in Rajshahi City, Bangladesh

Abstract: Obesity has become a new challenge for health care providers in the world, which leads to reduced life expectancy or increased health problems. The aim of the present study was to assess the prevalence and risk factors of obesity and hypertension among the undergraduate and postgraduate students in Rajshahi city. About 675 students were interviewed by standard questionnaires with their verbal consents. In this study, we found that a major portion of the population (13.93% which is about 94 students out of 675) were overweight and 61 students (9.04%) were obese at different stages on the basis of Body Mass Index (BMI) values where 75.41% and 31.15% were male and female students, respectively. About 31.15% of the obese students came from families with monthly income of 31000-40000 taka and 29.50% obese students have at least one obese parent. We also observed that about 32 students (52.46%) out of 61 obese students were pre-hypertensive and 34.43% obese students were stage I hypertensive patient. In this study, we found that the most common risk factors of obesity and hypertension among university students were sedentary life style, physical activity less than 30 min/day, smoking, frequent intake of soft drinks, fast food and food rich in fats (Junk food). This may be the first health survey conducted regarding obesity and hypertension among these university students in Bangladesh, which might be helpful for health workers to raise awareness among the mass people.

Evaluation of hydrogeological conditions through vertical electrical soundings survey at Mankiganj pourashava, Manikganj, central part of Bangladesh

Abstract: The Pourashava area of Manikganj, located in the central part of Bangladesh is treated as arsenic hotspot in the country as the outcome of various studies concludes that almost 80% of the domestic tube wells at this area exceed arsenic level of Bangladesh standard (50 μg/l) for drinking water. To enhance the potable water supply in the area, 15 geoelectric soundings survey using Schlumberger configuration with spreading AB/2 = 300 meters has been executed to decipher the subsurface lithology distribution and aquifers at different depths, to determine the lateral and vertical extent of aquifer at the area. Correlation of the analyzed VES results with primary and secondary borelogs, the subsurface sequence of the area is broadly divided into two geoelectric units. Firstly, the near surface geoelectric unit of resistivity less than 20.0 Ω-m represents the top soil composed of silty clay to clay. The thickness of this layer varies from 1 meter to 5 meters. The second geoelectric unit represents the sand layer and is characterized by a resistivity range of 21.0 to 190.0 Ω-m. This unit encompasses the very fine sand with variable thickness of 2 to 248m while resistivity is from 21.0 to 30.0 Ω-m, very fine to fine sand having thickness from 174-280m and geoelectric value ranges from 31.0 to 40.0 Ω-m, fine sand with resistivity from 44.0 to 50.0 Ω-m, fine to medium sand having resistivity from 51.0 to 70.0 Ω-m, medium sand and medium to coarse sand with resistivity value 75.0 to 110.0 Ω-m, and 140.0 to 190.0 Ω-m, respectively. The ultimate thickness of this unit could not be determined due to limited spread of survey but at least continues to a depth of 300 m. In the context of groundwater storage, the second geoelectric unit acts as the regional aquifer and is used for groundwater development in the Pourashava area for water supply. Bangladesh J. Sci.

Sustainable energy sources in Bangladesh: A review on present and future prospect

Abstract: Bangladesh is a small country with its large population struggled with several challenges over the last few decades, including overpopulation, power grid disruptions, floods, and global warming. Sufficient rate of energy production is must for a developing country, but quickly expanding population and overall economic growth interrupt the energy sector. Renewable energy plays a vital role to contribute in this sector. For becoming an agricultural country biomass is an important sustainable energy source for this country. Organic crop residues, animal waste, and municipal solid waste are the most accessible biomass energy sources in this country. On the other hand, by using the membrane gas separation technology the quality biogas can be improved and it helps the environment from the toxic CO2 which is a major element of biogas. This study represents the extension, potential and innovations identified with the utilization of biomass assets. Besides the improvement of biogas also discussed in this paper. This paper also represents the various initiatives conducted by the government that are all relevant to biomass energy. This work further can be studies to innovate different biomass technology and to improve the quality of biogas.

Role of RNase on microbial community analysis in the rice and wheat plants soil by 16S rDNA-DGGE

Abstract: In this work, we reported the role of RNase on microbial community analysis from soil samples. The amounts of chemical components were measured from the adjoining soil of rice and wheat plants. The chemical properties of these soils were rich in surface level as compared to other soil layers. Total DNA was extracted from freshly collected soils. To obtain pure DNA, half of the sample was incubated with RNase and half was without RNase. A total of 16S rDNA fragments were amplified and analyzed by Denaturing Gradient Gel Electrophoresis (DGGE). RNase-treated DNA followed by PCR resulted in a PCR product of good yield and integrity. DGGE bands and cluster analysis indicated a significant difference between the patterns obtained from RNase-treated and RNase non-treated samples. The sequencing results of 16S rDNA fragments from DGGE profiles of soil samples indicated that the dominant bacteria are composed of different gene sequences. This is an interesting preliminary observation which indicates that the RNase treatment prior to amplification and DGGE analysis modifies the pattern obtained. Therefore, it is suitable for community analysis of agricultural plant soil samples as well as environmental samples.
