Introduction: Multi-drug resistant tuberculosis (MDR-TB) is a public health crisis throughout the world including Bangladesh particularly due to its complexities in diagnosis, longer treatment regimen, and adverse drug reaction. Nutritional supplementation has significant impact on patient’s weigh gain and optimum weight gain is a biomarker of treatment response. The objective of this study was to measure body mass index (BMI) progress among MDR-TB patients in different phases of treatment. Methodology: A prospective observational study was conducted from March 2010 to July 2015 in Chest Disease Hospital (CDH), Rajshahi and different communities of Rajshahi Division, Bangladesh. A total of 233 confirmed MDR-TB patients were selected from CDH who received treatment and nutritional support from ongoing national TB control program (NTP). They received free diagnosis, follow up tests, treatment and nutritional support as regular diet as well as cash amount Bangladeshi taka (BDT.) 1000 per month in CDH. Along with treatment, they also received only cash amount BDT. 1500 per month as nutritional support at community level. Weight measurement was taken at regular interval from enrollment to completion of treatment. Chi-square, paired t-test and linear regression analysis were used in this study.

The purpose of this study was to investigate the physiological responses of drought-tolerant and drought-susceptible soybean genotypes to exogenous abscisic acid(ABA) application during progressive soil drying at seedling stages. Five-day old soybean seedlings were transplanted into PVC tubes filled with soil mixture. Seedlings were watered daily with similar water volumes until second trifoliate leaves emerged, and thereafter soil drying with or without exogenous ABA application was imposed. Half of the seedlings of each genotype were left for regular watering as control plants. Soil water status declined significantly over seven days of withholding water supply for both genotypes. Leaf expansion rate, stomatal conductance(g_s), leaf water potential(ψ_w), and relative water content of leaves(%RWC) declined significantly under soil drying as well as soil drying with ABA application, compared to their values for well-watered soybean genotypes. However, a drought-tolerant genotype(C12) responded more rapidly than a drought-susceptible genotype(C08) after imposition of soil drying and soil drying with exogenous ABA. In addition, application of exogenous ABA to water-restricted soybeans resulted in higher %RWC and ψwin the drought-tolerant than in the drought-susceptible genotype. Compared to the drought-susceptible genotype, the drought-tolerant genotype was more responsive to exogenous ABA application, resulting in a higher root-to-shoot ratio.

Air-stripping method was used to remove ammonia from the wastewater collected from natural gas fertilizer factory. Different materials were used as packing materials for the air stripping system. The effect of pH over 10.5, air-water flow ratio, nature of packing materials, height of materials and initial influent concentration of ammonia on air stripping unit were investigated. An attempt has been made to find out the stripping con-stant. Stripping constant was found to be .001, 0014, .001 and .0009 for coal, plastic ring, stone chips and wood chips, respectively. Best result was found for plastic ring for its higher surface area. Wood chips did not give good result, because the chips amalgamate with each other and hence reduces the surface area.

Transportation Problems (TP), as is known, are a basic network problem which can be formulated as a Linear Programming Problem (LPP). Transportation networks are built up in order to save transportation cost. In the solution procedure of a TP, finding an Initial Basic Feasible Solution (IBFS) is necessary to obtain the optimal solution. Optimality gives us the optimal route that prompts either most extreme benefit or least aggregate cost whichever is required. In this research paper, a new method named Least Cost Mean Method is proposed to obtain a better IBFS where row penalty and column penalty is brought out by the mean of lowest and next lowest cost of each row and each column of the cost matrix. The method is illustrated with numerical examples. To verify the performance of the proposed method, a comparative study is also carried out and observed that it is computationally easier and yielding comparatively better solution.

Background: Cholecystectomy is one of the most now common abdominal surgeries performed every day. The incidence of bile duct injury (BDI) following open cholecystectomy is only 0.1% - 0.2%. After the introduction of laparoscopic cholecystectomy, the incidence has gone up to 0.4% - 0.7%. The present study is a prospective analysis of all patients with bile duct injury who were admitted to Dhaka Medical College Hospital during or at a variable period following cholecystectomy. Methods: To determine the pattern of presentation of iatrogenic biliary injury following cholecystectomy in the department of surgery of Dhaka Medical College Hospital, a total of 30 patients were purposively selected from May 2018 to November 2018. Patient particulars, records of physical and clinical evaluation, and operative details were collected by individual researchers. Data analysis was done by SPSS for windows version 21. Results: BDI was found very common among the age group 21 - 30 yrs (36%) and female dominant (60%). Majority of the patients presented with abdominal pain (96%), intra-abdominal collection (88%), biliary peritonitis (68%), cholangitis (60%), and obstructive jaundice (40%), and biliary fistula (40%). Laparoscopic cholecystectomy (84%) was the principal cause of biliary injury in our study. 48% of patients experienced clinical features within 7 days post-cholecystectomy. Per-operative diagnosis was done in only 12% of cases. 44% of patients in this study were recognized as Bismuth grade-3, followed by 36%, grade-2 patients. Management outcomes included wound infection (41.66%), minor bile leak (25%), peritonitis (8.33%), and renal impairment (8.33%). Conclusion: The effect of BDI is an extremely distressful clinical condition for the patients and their family members, hence proper care and management protocol should be followed.

Consider X and Y are two real or complex Banach spaces. We introduce and study a modified Gauss-type proximal point algorithm (in short modified G-PPA) for solving the generalized equations of the form 0 ∈h(x) + H(x), where h : X → Y is a smooth function on Ω ⊆X and H : X ⇉2Y is a set valued mapping with closed graph. When H is metrically regular and under some sufficient conditions, we analyze both semi-local and local convergence of the modified G-PPA. Moreover, the convergence results of the modified G-PPA are justified by presenting a numerical example.

In this paper, security issue in multiple input multiple output (MIMO) multicasting system has been analyzed in the presence of a group of eavesdroppers in cognitive radio networks (CRNs). Primary base station (PBS) and secondary base station (SBS) communicate with multiple primary and secondary receivers, respectively via a precoding relay having multiple antennas. At first, considering interference the secrecy multicast capacity at the primary receivers (PRs) and the secondary receivers (SRs) has been calculated and investigated the impact of interferences on it. Then, the zero-forcing (ZF) precoding technique at the relay has been employed which enhances the secrecy multicast capacity at the PRs and SRs by zeroing the impact of interference on each other. Secondly, the existing constructive interference energy of the communication medium employing selective precoding (SP) technique at the relay has been used to improve the secrecy multicast capacity of the PRs and SRs. Finally, phase alignment precoding (PAP) technique at the relay has been introduced which uses the destructive part of interference for further increase in the secrecy multicast capacity at the PRs and SRs. It is observed that among the three precoding techniques, the best performance is achieved by using the PAP at the relay in terms of secrecy multicast capacity and secure outage probability analysis. This is due to the fact that PAP technique at the relay not only uses the constructive interference part but also it rotates the destructive interference part in such a way that the resulting interference is always instantaneously constructive. So using these precoding relays interference power can be used to enhance system performance without increasing base station power.

At the Genetics and Plant Breeding Laboratory of the Department of Agronomy and Agricultural Extension, University of Rajshahi, Bangladesh, strawberry in vitro propagation was done. Five Benzylaminopurine (BAP) concentrations were utilized for shoot induction—0.0 mg/L (Control), 0.5 mg/L, 1.0 mg/L, 1.5 mg/L, and 2.0 mg/L and five Indole Buteric Acid (IBA) concentrations—0.0 mg/L(Control), 0.5 mg/L, 1.0 mg/L, 1.5 mg/L, and 2.0 mg/l—were used for the induction of the root. The highest mean amount of shoots (eight) and length of the shoot (3.40 cm) were observed at a concentration of BAP of 0.5 mg/L. Festival also had the highest mean amount of leaves (6) when we used the identical concentration, while RABI-3 and Camarosa did the least well. The IBA of 0.5 mg/L concentration of rooting performed the best across all metrics tested among the five concentrations. The longest (3.3 cm) roots and most roots (7) were likewise obtained from this concentration in Festival. However, RABI-3 and Camarosa performed worse than Festival in the same concentration. Half-strength MS media without IBA concentration showed no response regarding root induction for each of the three cultivars.
