‘BARI Masur-9’: An extra-early lentil cultivar for a rice-based cropping system in Bangladesh
No full textLentil (Lens culinaris Medik) is the third-most important grain legume in the world. In Bangladesh, it is important for human food and nutrition, animal feed, and sustainable rice-based cropping systems. However, lentil area is declining due to competition with other winter and spring crops, particularly irrigated spring rice (boro rice; Oryza sativa L.). To increase lentil production, the extra-early (<95 d) lentil line LRIL-22-70 was selected to grow in the short fallow period between monsoon and spring rice under a proposed new cropping pattern. LRIL-22-70 was identified from a recombinant inbred line population through rigorously evaluated in diverse agro-ecological conditions of Bangladesh and released for commercial cultivation by Pulses Research Centre, BARI, as ‘BARI Masur-9’ (Reg. no. CV-36, PI 700307) in 2018. BARI Masur-9 is a transgressive segregant for earliness (matures in <93 d) and fits well in the new monsoon rice–lentil–spring rice cropping pattern. It is a medium-seeded (2.38 g 100–1 seed) cultivar with high tolerance to Stemphylium blight. The average seed yield of BARI Masur-9 was 1,201 kg ha–1, with higher concentrations of Fe (73 mg kg−1) and Zn (61 mg kg−1) compared with other genotypes; thus, BARI Masur-9 contributes to combatting micronutrient malnutrition in Bangladesh. BARI Masur-9, the first extra-early lentil cultivar, can successfully be grown to replace fallow between rice as a new cropping pattern monsoon rice–lentil (BARI Masur-9)–spring rice in about 8 million ha in Bangladesh, eastern Indian states, and eastern Nepal
Effect of External Shading and Window Glazing on Energy Consumption of Buildings in Bangladesh
No full textThis thesis is submitted to the Department of Electrical and Electronic Engineering, Khulna University of Engineering & Technology in partial fulfillment of the requirements for the degree of Master of Science in Electrical and Electronic Engineering, September, 2014.Cataloged from PDF Version of Thesis.Includes bibliographical references (pages 56-59).Energy efficiency of buildings is attracting significant attention from the research
community as the world is moving towards sustainable buildings design. Energy efficient
approaches are measures or ways to improve the energy performance and energy
efficiency of buildings. This study investigated various energy-efficient approaches for
residential building. External shading controls the solar energy on a window and the
energy transfer within the room through the window. In the present study, the effect of
overhang and fin on single clear glazing window as well as the effect of advanced glazing
on the solar energy transmitted into or lost from the room through the fenestration areas
have been evaluated for typical residential buildings in Bangladesh, using EnergyPlus
software in different frontage wall orientation. Four types of glazing (single clear, double
low-E opaque, double layer argon gapping, and double clear glazing) and six types of
window shading ( with different dimensions of overhang and fin) are used in this project.
It was found that appropriate overhangs or side fins in the north, south, west and east
windows would lead to the optimal reduction of the annual energy transferred into the
buildings and can have an energetic behavior equivalent to high performance glazing. As
'V
well as the energy consumption for north facing window with overhang and side fin in left
side is the lowest and generously shaded (like north facing) south-facing window can also
be used for residential building with considering cp index i.e., ener
11 gy consumption can be reduced by proper window shading. In addition, double low-E opaque glazing in window
is more efficient for energy saving in building. But with considering illuminance and
energy consumption Double low-E clear (Argon) is best selection for Bangladeshi climate.Md. Jahangir AlamMaster of Science in Energy Technolog
Development of a microinjection-based protocol for the cryopreservation of Japanese whiting Sillago japonica embryos
No full textMobile Network Planning and KPI Improvement
No full textIn this project, coverage planning in GSM networks as well as capacity and frequency planning has been studied. Various signal interruptions and the necessary steps to remove those interruptions in order to maintain signal quality in mobile communication have been studied. Precautions that should be taken for reducing the effects of interruptions have also been discussed. A drive test has been performed as a part of the improvement process. Guidelines for key performance indicators (KPI) pave the way for radio network quality, coverage and the smooth functioning of the GSM system

Application of Nonlinear Site Response Analysis in Coastal Plain South Carolina
No full textThe 1933 Long Beach, 1957 San Francisco, 1967 Caracas, 1985 Mexico City, 1989 Loma Prieta, and 1994 Northridge earthquake events left evidences of how the local site condition can affect the characteristics of propagating earthquake wave from the bedrock through the top soil. The ground motion amplitude, frequency content or the duration can be affected by the local site condition and thus can cause significant amplification or de-amplification to the original bedrock motion which can seriously affect the structures. Quantification of such site effect on ground motions is a challenging task. This dissertation is dedicated to improve the existing ground response quantification techniques and the related knowledge base. The first major attempt towards ground response quantification was the development of the 1994 NEHRP (BSSC, 1995) seismic site factor provision. Since the development of the NEHRP provisions, several studies have found these factors to produce inadequate predictions for the state of South Carolina. In an attempt to generate seismic site factors based on conditions specific to South Carolina Coastal Plain (SCCP), a series of nonlinear one-dimensional ground response analyses are performed by this author as part of a research team considering appropriate soil profiles and location specific ground excitations. After the generation of this new site factor model, a systematic repercussions study is performed by applying earthquake loads, considering both NEHRP and the new site factors, on typical highway bridge structures
Weight-length, length-length relationships and form factor of three flatfish species from the Bay of Bengal, Bangladesh
No full textBiometrics such as weight-length relationships (WLRs), length-length relationships (LLRs), as well as form factor (a3.0) were investigated for three flatfish species, Cynoglossus lingua, Cynoglossus arel, and Brachirus pan which were captured using seines and gill nets between September 2021 and March 2022 from the Bay of Bengal, Bangladesh. The lengths were measured to adjacent 0.1 cm accuracy with a digital caliper and weights to the accuracy of 0.01 g with a digital balance for each individual. The WLRs were accurately adjusted for all species (r2 > 0.9500). Brachirus pan had the lowest b value of 2.9543, whereas C. arel had the highest b value of 3.2924 amongst the three species. For the investigated species of fish, LLRs were also highly significant (r2 > 0.9600, p < 0.01). The estimated form factor values were 0.0023 for B. pan, 0.0026 for C. arel, 0.0027 for C. lingua. New maximum total lengths for C. arel and B. pan have also been recorded. Since there are no weight-length relationships (WLRs), length-length relationships (LLRs), as well as form factor (a3.0) data for these species in Bangladesh; the information supplied here expands the depth of knowledge for these species
