    The Project on The Revision and Updating of the Strategic Transport Plan for Dhaka (RSTP) Final Report 12. FORMULATION OF THE URBAN TRANSPORT MASTER PLAN Development of the RSTP Urban Transportation Master Plan (1) Methodology The development of the RSTP Urban Transportation Master Plan adopted the following methodology (see Figure 12.1): (i) Elaborate the master plan network through a screen line analysis by comparing the network capacity and future demand. (ii) Identify necessary projects to meet future demand at the same time avoiding excessive capacity. (iii) Conducts economic evaluation of each project to give priority on projects with higher economic return. (iv) Conduct preliminary environmental assessment of every project and consider countermeasures against environmental problems, if any. (v) Make a final prioritization of all physical projects by examining their respective characteristics from different perspectives. (vi) Classify the projects into three categories, namely short-, medium- and long-term projects, by considering the financial constraints. (vii) Prepare an action plan for short-term projects together with “soft” measures. Mid-term Project Source: RSTP Study Team Figure 12.1 Development Procedure for the Master Plan 12-1 The Project on The Revision and Updating of the Strategic Transport Plan for Dhaka (RSTP) Final Report (2) Output of the Transportation Network Plan The RSTP urban transportation network plan was developed based on a review and a modification of the STP network plan. The main points of the modification or adoption of the STP network master plan are as follows: i. Harmonization with future urban structure, land-use plan and development of network plan.

  • Sediment Dispersal Process and Its Management in the Meghna
    Sediment Problems and Sediment Management in Asian River Basins 203 (Proceedings of the Workshop held at Hyderabad, India, September 2009). IAHS Publ. 349, 2011. Sediment dispersal processes and management in coping with climate change in the Meghna Estuary, Bangladesh MAMINUL HAQUE SARKER, JAKIA AKTER, MD RUKNUL FERDOUS & FAHMIDA NOOR Center for Environmental and Geographic Information Services (CEGIS), House no.6, Road no. 23/C, Gulshan-1, Dhaka-1212, Bangladesh [email protected] Abstract Due to flat terrain and dense population, the Bengal Delta is highly vulnerable to sea level rise. At present the delta building process is active in the Meghna Estuary. Information on sediment dispersal processes in the estuary and their response to different exogenic and anthropogenic forces is an important requirement for managing the sediment and developing adaptive measures to counter the potential impact of climate change. Historical maps, satellite images and tidal water level data were analysed and the response of the Meghna Estuary to extreme events, e.g. the 1950 Assam earthquake, as well as anthropogenic interventions, was assessed. The issue of sediment management was addressed, based on an understanding of the response of the estuary to the extreme natural event and anthropogenic interventions, along with an assessment of the response of the estuary to sea level rise. Among other interventions, emphasis has been directed to promoting vertical accretion by injecting sediment into polders. Key words Bengal delta; Meghna Estuary; sea level rise; sediment dispersal processes; vertical accretion; sediment injection INTRODUCTION Deltas are a large accumulation of both fluvial and marine sediments which have infilled river mouths and extended onto the continental shelf (Fookes et al., 2007).

  • Effect of Nitrogen and Boron on the Yield of Wheat Cv. Kanchan
    J. Bangladesh Agril. Univ. 3(2): 215-220, 2005 ISSN 1810-3030 Effect of nitrogen and boron on the yield of wheat cv. Kanchan M.M. Khan', A.K. Hasan2, M.H. Rashid2, and F. Ahrned3 Palli Karma Sahayak Foundation (PKSF), Sher-e-Banglanagar, Dhaka, 2Department of Agronomy and 3 Department of Agroforestry, Bangladesh Agricultural University, Mymensingh Abstract An experiment was carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from January to April 2004 to study the effect of different levels of nitrogen and boron on the yield of wheat cv. Kanchan. The treatments included four levels of nitrogen VIZ., 45, 60, 85 and 110 kg N ha-1 and four levels of boron viz., 0, 1, 2 and 3 kg B ha-1. The experiment was laid out in a Randomized Complete Block Design with three replications. The results revealed that Yield and yield contributing characters were influenced significantly by both levels of nitrogen and boron. Among the levels of nitrogen, 110 kg N ha-1 produced the highest grain (5.54 t ha-1)and straw (8.21 t ha-1 ) yields. The lowest grain (3.23 t ha-1) and straw (5.52 t ha-1) yields were observed with the application of 45 kg N ha-1. The highest grain (4.95 t ha-1)and straw (7.38 t ha 1) yields were produced With 3 kg B ha-1. The minimum grain (3.59 t ha-1)and straw (6.14 t ha-1)yields were found in the control treatment.

  • Connecting Bangladesh: Economic Corridor Network
    Connecting Bangladesh: Economic Corridor Network Economic corridors are anchored on transport corridors, and international experience suggests that the higher the level of connectivity within and across countries, the higher the level of economic growth. In this paper, a new set of corridors is being proposed for Bangladesh—a nine-corridor comprehensive integrated multimodal economic corridor network resembling the London Tube map. This paper presents the initial results of the research undertaken as an early step of that development effort. It recommends an integrated approach to developing economic corridors in Bangladesh that would provide a strong economic foundation for the construction of world-class infrastructure that, in turn, could support the growth of local enterprises and attract foreign investment. About the Asian Development Bank COnnecTING BANGLADESH: ADB’s vision is an Asia and Pacific region free of poverty. Its mission is to help its developing member countries reduce poverty and improve the quality of life of their people. Despite the region’s many successes, it remains home to a large share of the world’s poor. ADB is committed to reducing poverty through inclusive economic growth, environmentally sustainable growth, and regional integration. ECONOMIC CORRIDOR Based in Manila, ADB is owned by 67 members, including 48 from the region. Its main instruments for helping its developing member countries are policy dialogue, loans, equity investments, guarantees, grants, NETWORK and technical assistance. Mohuiddin Alamgir

Synthesis, physical and spectroscopic data for all new compounds General considerations: All reactions were performed under an atmosphere of argon by using standard Schlenk or dry box techniques; solvents were dried over Na metal, K metal or CaH2. Reagents were of analytical grade, obtained from commercial suppliers and used without further purification. 1H, 13C, 11B, and 27Al{1H} NMR spectra were obtained with a Bruker AV 300, Bruker AV 400 or Bruker AVIII 400MHz BBFO1, spectrometers at 298 K unless otherwise stated. NMR multiplicities are abbreviated as follows: s = singlet, d = doublet, t = triplet, sept = septet, m = multiplet, br = broad signal. Coupling constants J are given in Hz. Electrospray ionization (ESI) mass spectra were obtained at the Mass Spectrometry Laboratory at the Division of Chemistry and Biological Chemistry, Nanyang Technological University. Melting points were measured with OptiMelt Stanford Research System. IR spectrum was measured using Shimadzu IR Prestige-21 FITR spectrometer. N-(2,6-diisopropylphenyl)pivalimidoyl chloride [(DippN=C(tBu)Cl)] was synthesized according to literature report.[1] Synthesis of compound 1: 1 was generated in situ using a modified literature procedure.[2] Phenyl hydrazine (0.99 t mL, 10.0 mmol) and NEt3 (2.09 mL, 15.0 mmol) were added dropwise to a THF solution of [(DippN=C( Bu)Cl)] (2.80 g, 10.0 mmol).
