In vitro propagation of Stevia rebaudiana Bert in Bangladesh
MS Uddin, MSH Chowdhury, MMMH Khan, MB Uddin, R Ahmed, MdA Baten
African Journal of Biotechnology , 2006,
Abstract: An experiment was conducted on in vitro culture of Stevia rebaudiana Bert, an important non-caloric sweetening herb to explore its potential for micro-propagation. Leaf, nodal and inter-nodal segments of the selected herb as explant were cultured on MS medium containing 2,4-D at 2, 3, 4 and 5 mg/L for callus induction. Inter-nodal segments initiated callus earlier than node and leaf. The highest amount of callus was found in MS medium with 3.0 mg/L 2,4-D and MS medium with 5.0 mg/L 2,4-D gave the poorest callus
Botulinum toxin for treatment of blepharospasm and hemifacial spasm
Soltanzadeh A,Javadian MDA
Tehran University Medical Journal , 1997,
Abstract: Botulinum toxin produced by Clostridium butolinum in one of the most fatal toxins known. Botulism is the name given to condition produced by this toxin. In recent years the diluted form of this toxin has been produced in injection form and used for treatment of hemifacial spasm and blepharospasm. This toxin blocks neuromuscular junction and inhibits acetylcholine release. In this article we reported 36 patients suffering from hemifacial & blepharospasm treated by injections of botulinum A toxin. 85 to 90 percent of patients responded well. The common complications of this drug were ptosis, hemifacial paresis, burning of the mouth and discoloration of the injection site. Generally speaking the patients preferred this toxin to taking oral medications which were less effective.

International Journal of Stochastic Analysis , 2006, DOI: 10.1155/jamsa/2006/98764
Abstract: We study a stochastic control problem for linear degenerate systems. We establish the existence of a classical solution of the degenerate Bellman equation by the technique of viscosity solutions, and the optimal policy is shown to exist from the optimality conditions.
Role of Mass Media in Promotion of Family Planning in Bangladesh
Saidul Hasan,Azizul Baten
Journal of Applied Sciences , 2005,
Abstract: This study has been made to examine the levels, differentials and determinants of female access to mass media in Bangladesh using data from Bangladesh Demographic and Health Survey (BDHS). Studies in access to mass media differentials provide information for assessing inequalities among women with respect to mass media. In response, about two fifths (39.0%) of the respondent listen to the radio weekly. Only 18.0% watch television weekly while only a little proportion of ever-married women read newspaper weekly. Multivariate analysis shows that respondents place of residence, education, economic status, geographical region, ownership of radio and ownership of TV appeared as most significant variables in determining access to mass media. This study helps to identify those underprivileged segments of women who experience lower access to mass media.

Performance of Nationalized and Private Commercial Banks in Bangladesh
Saidul Hasan,Azizul Baten
Journal of Applied Sciences , 2005,
Abstract: This study was conducted to evaluate the comparative performance of the public and private commercial banks operating in Bangladesh with loan default as a big concern. Janata Bank (JB) has been taken as the sample bank to represent the Nationalized Commercial Banks (NCBs) and National Bank Ltd. (NBL) has been selected as the sample bank to represent the Private Commercial Banks (PCBs), respectively. A statistical analysis of dummy variables and log linear method have been used to compare the performance of NCBs and PCBs with respect to their loan default. The study (both dummy variable and log linear) reveals that the rate of default is the highest in NCBs as compared to PCBs. In sample banks’ default rate, we observe that both JB and NBL have alarming default rate while NBL’s default rate is a bit lower than that of JB. However, better situation of NBL in terms of loan recovery than JB. The study suggests that if the bank can successfully screen out the fake entrepreneurs and identify the genuine entrepreneurs; the recovery rate will automatically rise.
Characterization of Fundamental Particles
Ben J Baten
Physics , 2000,
Abstract: This report provides an alternative to the Standard Model of particle physics. The model described here is based on results from Quantum Field Mechanics, according to which all fundamental particles and interactions originate from the interaction of two pre-space/pre-time protofields. In contrast with the Standard Model, (virtual) interaction-particles are absent in the description of any of the four fundamental interactions. Electrons perform a single quantum beat process while mesons and baryons have, respectively, two and three bound quantum beat processes. Quantum Field Mechanics suggests that the charge of an electron and positron can be identified with the two possible phases of a quantum beat process as observed in the electromagnetic protofield. This report assumes that short-range binding interaction between quantum beat processes has a masking effect on the externally observable charge of hadrons. Using this assumption, the internal structure of particles is derived from their known particle charges and relative masses. The particle structures are used to obtain the so-called charge-quantum phase law. The fractional charge of quantum beat processes inside a particle is deduced by rewriting the charge-quantum phase law in terms of a linear combination of charge contributions of individual constituent quantum beat processes. Strangeness and isospin are mathematically defined in terms of the quantum beat phases of sets of particles of the same type. Application of conservation laws to particle processes leads to relations between quantum phase, strangeness and isospin.
Salinity Intrusion in Interior Coast of Bangladesh: Challenges to Agriculture in South-Central Coastal Zone  [PDF]

American Journal of Climate Change (AJCC) , 2015, DOI: 10.4236/ajcc.2015.43020
Abstract: This paper investigates the impacts of salinity on crop agriculture in south-central coastal zone of Bangladesh, more particularly interior coast. The coastal areas of Bangladesh, with near flat topography and location at the tip of “funnel shaped” Bay of Bengal, are susceptible to a number of natural hazards such as cyclones, tidal surges, salinity intrusion, riverbank erosion, and shoreline recession. The coastal zone of Bangladesh, especially exposed coast has come into focus in a number of policy and academic studies for salinity intrusion, but with the accelerated impacts of climate change salinity extends from the exposed to the interior coast hampering crop production. To investigate extent of salinity level in interior coast and its impact on crop agriculture, this study tested irrigation water collected in between October and December 2011 from the lower Meghna at Gosairhat upazila in Shariatpur district and interviewed experts and local farmers. This study estimated that salinity concentration of surface water was 1.3 dS/m which was 0.8 dS/m higher than the earlier estimation by ICZMP (Integrated Coastal Zone Management Plan) in 2003. The test further revealed that Chloride ion concentration in irrigation water was 500 ppm, pH level was 7.99 and concentration of Carbonate ion was 221 ppm, which were much higher than the desired level. Estimated salinity concentration has already put a threat to the crop production and a significant yield loss has already been noticed in dry season. In the changing scenario of sea level rise, it has been predicted that the increasing concentration of salinity would create more pressure to the farmer by reducing yield on one hand and threatening livelihood, income generation and food security on the other hand. Therefore, to reduce the future loss and prevent the present loss, the study recommends leaching and selecting salinity tolerant crop varieties as adaptation techniques.

Journal of Geoscience and Environment Protection (GEP) , 2018, DOI: 10.4236/gep.2018.67007
Abstract: Water and nitrogen are two key elements required for successful rice cultivation. We examined the responses of nitrogen and water management on methane emission of Boro rice in the field laboratory of Bangladesh Agricultural University research farm, Mymensingh. Three treatments were studied in the field experiment viz, T1: Control plot (no nitrogen fertilizer), T2: Urea super granule (78 kg N/ha), T3: Prilled urea (104 kg N/ha) with three replications under two water management of Continuous Standing Water (CSW) and Alternate Wetting and Drying (AWD). Air samples were collected by the closed-chamber method and methane gas was determined by gas chromatography. The highest CH4 emission was found from CSW plots and the lowest from AWD plots. Under CSW condition, the effects of urea treatments on CH4 emission were not significant. In case of urea treatments, the highest CH4 emission was observed from treatment T3 under CSW condition and T2 under AWD condition and the lowest emission was from the control treatment. The overall results suggest that prilled urea and urea super granule should be applied under AWD and CSW condition, respectively to keep less CH4 emission from irrigated rice agriculture.
