The Islamist Militant Threat in Bangladesh

Description: This report discusses the current security climate in Bangladesh in regards to terrorism. Bangladesh is attractive to jihadists because it is a politically destabilized Muslim majority nation that could offer inroads to both Burma, through the alienated Muslim Rohingya refugee group, or to neighboring India.

Bangladesh: Background and U.S. Relations

Description: This report discusses the key issues regarding U.S.-Bangladesh Relations. U.S. policy toward Bangladesh emphasizes support for political stability and democracy; social and economic development; and improvement of human rights. The United States has long-standing supportive relations with Bangladesh and has viewed Bangladesh as a moderate voice in the Islamic world.

Toward a philosophy of water: Politics of the pollution and damming along the Ganges River.

Description: This thesis sets out to develop a beginning of a philosophy of water by considering philosophical implications of ecological crises currently happening along the waters of the Ganges River. In my first chapter, I give a historical account of a philosophy of water. In my second chapter, I describe various natural and cultural representations of the Ganges, accounting for physical features of the river, Hindu myths and rituals involving the river, and ecological crises characterized by the pollution and damming of the river. In my third and final chapter, I look into the philosophical implications of these crises in terms of the works of the contemporary philosopher Bruno Latour.

ElectroChemical Arsenic Removal (ECAR) for Rural Bangladesh--Merging Technology with Sustainable Implementation

Description: Today, 35-77 million Bangladeshis drink arsenic-contaminated groundwater from shallow tube wells. Arsenic remediation efforts have focused on the development and dissemination of household filters that frequently fall into disuse due to the amount of attention and maintenance that they require. A community scale clean water center has many advantages over household filters and allows for both chemical and electricity-based technologies to be beneficial to rural areas. Full cost recovery would enable the treatment center to be sustainable over time. ElectroChemical Arsenic Remediation (ECAR) is compatible with community scale water treatment for rural Bangladesh. We demonstrate the ability of ECAR to reduce arsenic levels> 500 ppb to less than 10 ppb in synthetic and real Bangladesh groundwater samples and examine the influence of several operating parameters on arsenic removal effectiveness. Operating cost and waste estimates are provided. Policy implication recommendations that encourage sustainable community treatment centers are discussed.

Arsenic remediation of drinking water using iron-oxide coated coal bottom ash

Description: We describe laboratory and field results of a novel arsenic removal adsorbent called 'Arsenic Removal Using Bottom Ash' (ARUBA). ARUBA is prepared by coating particles of coal bottom ash, a waste material from coal fired power plants, with iron (hydr)oxide. The coating process is simple and conducted at room temperature and atmospheric pressure. Material costs for ARUBA are estimated to be low (~;;$0.08 per kg) and arsenic remediation with ARUBA has the potential to be affordable to resource-constrained communities. ARUBA is used for removing arsenic via a dispersal-and-removal process, and we envision that ARUBA would be used in community-scale water treatment centers. We show that ARUBA is able to reduce arsenic concentrations in contaminated Bangladesh groundwater to below the Bangladesh standard of 50 ppb. Using the Langmuir isotherm (R2 = 0.77) ARUBA's adsorption capacity in treating real groundwater is 2.6x10-6 mol/g (0.20 mg/g). Time-to-90percent (defined as the time interval for ARUBA to remove 90percent of the total amount of arsenic that is removed at equilibrium) is less than one hour. Reaction rates (pseudo-second-order kinetic model, R2>_ 0.99) increase from 2.4x105 to 7.2x105 g mol-1 min-1 as the groundwater arsenic concentration decreases from 560 to 170 ppb. We show that ARUBA's arsenic adsorption density (AAD), defined as the milligrams of arsenic removed at equilibrium per gram of ARUBA added, is linearly dependent on the initial arsenic concentration of the groundwater sample, for initial arsenic concentrations of up to 1600 ppb and an ARUBA dose of 4.0 g/L. This makes it easy to determine the amount of ARUBA required to treat a groundwater source when its arsenic concentration is known and less than 1600 ppb. Storing contaminated groundwater for two to three days before treatment is seen to significantly increase ARUBA's AAD. ARUBA can be separated from treated water by coagulation and ...

Climate-Resilient Low Emission Development in Bangladesh (Fact Sheet)

Description: Bangladesh is widely considered to be one of the nations most threatened by climate change. With two-thirds of the country less than 20 feet above sea level, the intrusion of salt into freshwater wells, frequent flooding, and the displacement of people from their homes is an ongoing threat. At the same time, the country's cities are rapidly growing, and the demand for energy is increasing at a corresponding rate.

Lessons Learned Through the Follow-up of the Long-Term Effects of Over-Exposure to an Ir192 Industrial Radiography Source in Bangladesh

Description: An industrial radiographer was accidentally over-exposed while taking the radiograph of weld-joints of gas pipe-lines in 1985 in Bangladesh. Symptoms of high radiation exposure occurred immediately after the accident and skin erythema developed leading to progressive tissue deterioration. The consequences of this over-exposure is being followed up to assess the long-term effects of ionizing radiation on the victim. Progressive tissue deteriorations have already led to multiple surgeries and successive amputations of the finger-tips so far. Lessons learned from this accident are also reported in this paper.

How Do I Use Renewable Energy in My Region?

Description: NREL can asses renewable energy resource information and integrate it with data using geographic information systems (GIS) and interface the data with key analytical models. Planners and energy developers use these integrated resource assessments to make decisions about the feasibility, cost-effectiveness, and risks of developing projects in specific locations and for regional planning.
