  • Advancement of Biodiesel in Bangladesh

Saifullah1, Md. Abdul Karim2, Md. Raisul Karim3 1, 2Department of Mechanical Engineering, IUBAT – International University of Business Agriculture and Technology, Dhaka 1230, Bangladesh 3Department of Mechanical Engineering, Dhaka University of Engineering and Technology, Gazipur 1700, Bangladesh Abstract:–This paper presents an overview of Biodiesel resources and research in Bangladesh. The energy sector of Bangladesh largely depends on natural gas and petroleum oil. But the reserves are inadequate to meet the energy demand for long term economic growth. Biodiesel can be an alternative to these fossil fuels. Biodiesel is non-toxic and biodegradable. The combustion of Biodiesel emits very less amount of COX, SOX, hydrocarbons and particulate matter. In Bangladesh, a good number of edible and non-edible Biodiesel feedstock is available. But the edible sources are not promising as they need arable lands for cultivation. The arable lands in Bangladesh are used for food production. About 47750 km of road and railway side arid lands can be used to produce non-edible Biodiesel feedstock. But Algae can be the most effective source of Biodiesel. Algae possess high productivity and high lipid content. Producing 1kg of Algae Biodiesel can fix 1.83 kg of CO2. Algae can be produced in non-arable lands, fresh water, salt water and waste water. In Bangladesh, about 4.418 million hectares of infertile land, 1.383 million hectares of water areas (lakes, rivers, costal saline water etc.) and 0.31 million hectares of ponds are available which can be used for Algae production.

The accessibility of these fluid powers is decreased because of the gigantic utilization of transportation. Normally the accessibility of energizes shifted depending up on surface of the earth. Couple of nations are holding enormous limit of oils. The remaining is buy from those nations. The expense of the fuel is additionally fluctuated depending up on the accessibility; henceforth the world exchanges can't ready to foresee the expense of the oil and to minimize the fuel utilization. From this basic circumstance compelled to locate another fuel which is utilized to infer the source as much as long. It starts to deliver oils from non palatable seed cakes. Jatropha curcas plant is one of the oil plants. The Jatropha seed cakes are utilized to deliver oils. The oil was mixed with Diesel and infers the vehicle. It gives closest proficiency when contrasted and immaculate diesel. At that point the administration starts to plant Jatropha curcas trees and deliver oil from itself.

Received: 1 February 2013; in revised form: 16 April 2013 / Accepted: 19 April 2013 / Published: 3 May 2013 Abstract: High temperature (HT) stress is a major environmental stress that limits plant growth, metabolism, and productivity worldwide. Plant growth and development involve numerous biochemical reactions that are sensitive to temperature. Plant responses to HT vary with the degree and duration of HT and the plant type. HT is now a major concern for crop production and approaches for sustaining high yields of crop plants under HT stress are important agricultural goals.

  • A Case Study of Bansi River, Savar, Dhaka, Bangladesh Kamrun Nahar Khan Mukti1
    UITS Journal Volume: 5 Issue: 1 Study of Sources of Pollution and its Effects on Water Quality and Human Habitat: A Case Study of Bansi River, Savar, Dhaka, Bangladesh Kamrun Nahar Khan Mukti1 Abstract—Bansi River catchment is surrounded with different land use activities ranging from urbanization to agriculture and quarrying. The objectives of this study are to establish the number of point and non-point sources pollution of Bansi River and to identify which area source pollutions have the potential to increase the pollution rate in this river with its effects. This study involved both field and laboratory data (secondary data) study. Field study is conducted to establish the number of sources pollution and its effects. The various parameters of the water such as Dissolved Oxygen, Biochemical Oxygen Demand, pH, Chlorine, etc. were examined. Laboratory data was collected from Bangladesh Water Development Board (BWDB) and Department of Environment (DOE). Based on an analysis that has compliance with these standards, it can be concluded that point and non-point sources pollution that toward the station (Nayarhat area) have potential to increase pollution rate in the River. Key words: Point sources pollution, Non-Point source pollution, Water Quality Analysis. Introduction Bansi River is located approximately 20 km far from of the Dhaka city. The Bansi is located within 2393 north latitude to 2381 north latitude and 9021 east longitude to 9026 east longitude. Savar area is on the bank of Eastern side and Nayarhat is on the western side of the Bansi River. The river system of Bansi River is spread in Dhaka district and in neighboring areas of Dhaka City.

DARREN A. PRUM KATHRYN KISSKA-SCHULZE ABSTRACT Effective January 1, 2012, the European Union (EU) instituted the first emissions trading scheme (ETS) for aviation, which affected the domestic and international commercial airlines flying into and out of the EU. The EU established the ETS to counter the global aviation sector’s role in releasing greenhouse gas (GHG) emissions; however, such measures were met with heavy opposition by foreign countries, the International Civil Aviation Organization (ICAO), various commercial airlines and the Air Transport Association of America (ATA).

The leaves and petioles of castor plants were collected from the earthen pot to determine the leaf and petiole nutrient contents. So this study provides a reliable account of the endogenic concentrations of nutrients present in petiole and their content in leaves including the morphological parameters such as plant height, stem diameter, leaf growth, fresh and dry weight of leaves, petiole and root length of the plant at 2 vegetative growth stages grown in Silty clay loam soil were attempted. The experiment revealed that the morpholog- ical parameters responded better in mature plant compared to young plant but the physiological parameter showed variations at 2 growth stages.
