Measuring the Severity of a Banking Crisis and Finding Its Associated Factors: How Are the Factors Different for Simple and Severe Banking Crises?  [PDF]
Anichul Hoque Khan, Hasnat Dewan
Theoretical Economics Letters (TEL) , 2014, DOI: 10.4236/tel.2014.49109
Abstract: This study measures the severity of a banking crisis by using its duration and the cost. Using this new methodology, we find that the factors associated with a severe banking crisis are not quite the same as those associated with a simple banking crisis. An ordered logit model and a large panel data set were used for this study. One of our major findings is that there exists a four-year time lag between an economic boom, or financial system liberalization, and the occurrence of a severe banking crisis in a country. This indicates that banking problems start much earlier than the time when they are revealed as banking crises. This study also finds that the lower the remains of a past banking crisis, the higher the probability of a severe banking crisis. It could be due to less-attentiveness of banking sector policy-makers with elapsed time. A high rate of inflation, existence of an explicit deposit insurance scheme, and a weak institutional environment are found to be common factors positively associated with both simple and severe banking crisis.
Does the Primary Condition for a Sustainable Human Development Meet the Feasibility Condition of Cost-Benefit Analysis?
Hasnat Dewan
Journal of Sustainable Development , 2011, DOI: 10.5539/jsd.v4n2p3
Abstract: The primary condition for a sustainable human development (SHD) uses both monetary and non-monetary indicators to determine the sustainable level of human development. As defined, this condition can be expressed in terms of the damage elasticity of human development, where damage is defined based on the non-monetary cost to the natural and social environments (NSE). A comparison between this sustainability condition and the feasibility condition of cost-benefit analysis (CBA) is useful for determining the sustainability premium or the deadweight loss. Since the cost-benefit methodology uses monetary estimates of all impacts and the primary condition for sustainable human development uses both monetary and non-monetary indicators, the two methodologies are unlikely to yield the same outcome unless there is a one-to-one relationship between monetary and non-monetary benefits and costs. Unlike the feasibility condition of CBA, the primary condition for a sustainable human development varies based on the level of human development and the damage to the NSE in any locality/country.
Effect of Annealing Temperature on Structural, Optical and Electrical Properties of Pure CdS Thin Films Deposited by Spray Pyrolysis Technique  [PDF]
A. Hasnat, J. Podder
Advances in Materials Physics and Chemistry (AMPC) , 2012, DOI: 10.4236/ampc.2012.24034

Effect of annealing temperature on the properties of CdS thin films are carried out in this work. Nanocrystalline cadmium sulphide (CdS) thin films were prepared using spray pyrolysis deposition (SPD) technique and the structural, optical and electrical properties were investigated for different annealing temperature (as deposited, 300, 400 & 500 C). The surface morphology and compositional properties studied by SEM and EDX respectively. The crystal structure of CdS thin film was studied by X-ray diffraction. The crystallite size and lattice constant of SPD CdS thin films were investigated. The optical parameters such as transmittance, absorption coefficient and energy band gap of the films with thermal annealing temperature was investigated by UV/VIS spectrophotometer. The variation of band gap values of CdS thin film samples were found to be in the range of 2.51 to 2.8 eV. Electrical resistivity measurements were carried out in fourprobe Vander Pauw method at different temperature. So CdS films may be a good candidate for suitable application in various optoelectronic devices.

Performance Optimization of a Six-Strand Tundish  [PDF]
Siddharth Gupta, Anupam Dewan
World Journal of Mechanics (WJM) , 2013, DOI: 10.4236/wjm.2013.33018

The aims of the present study are to predict and improve inclusion separation capacity of a six strand tundish by employing flow modifiers (dams and weirs) and to assess the influence of inclusion properties (diameter and density) together with velocity of liquid steel at the inlet gate on the inclusion removal efficiency of a six-strand tundish. Computational solutions of the Reynolds-Averaged Navier-Strokes (RANS) equations together with the energy equation are performed to obtain the steady, three-dimensional velocity and temperature fields using the standard k-ε model of turbulence. These flow fields are then used to predict the inclusion sepapration by numerically solving the inclusion transport equation. To account for the effects of turbulence on particle paths a discrete random walk model is employed. It was observed that with the employment of flow modifiers, the inclusion separation capacity of tundish increases without any large variation in the outlet temperatures. It is shown that inclusion properties and velocity are important parameters in defining the operating conditions of a six-strand tundish.

Abstract: This study analyzed the long run relationship between trade openness and output growth for Pakistan using annual time series data for 1972-2010. This study follows the Engle and Granger co integration analysis and error correction approach to analyze the long run relationship between the two variables. The Error Correction Term (ECT) for output growth and trade openness is significant at 5% level of significance and indicates a positive long run relation between the variables. This study has also analyzed the causality between trade openness and output growth by using granger causality test. The results of granger causality show that there is a bi-directional significant relationship between trade openness and economic growth.

Prevalence of hepatitis B and C virus seropositivity among tribal and non-tribal voluntary blood donors of Rangamati, Bangladesh
G Dewan
Journal of Universal College of Medical Sciences , 2013, DOI: 10.3126/jucms.v1i4.9571
Abstract: INTRODUCTION: Prevalence of hepatitis B and C virus seropositivity is not defined among blood donors of Rangamati district of Bangladesh. This region is mainly inhabited by tribal population of multiethnic stocks. Government policy formulation for tribal health is lacking data on this issue among tribal population of Bangladesh. MATERIALS AND METHODS: A retrospective study on eight years data from 2005 to 2013 carried out to define hepatitis B and C virus related seropositivity among tribal and non-tribal voluntary blood donors in Rangamati General Hospital. RESULTS: A total of 4974 unit of blood were screened during this period. Of them 2760 unit were from tribal and 2214 unit from non-tribal donors. Result shows there is higher prevalence of hepatitis B seropositivity among tribal donors (?=100) compared to non-tribal (n =26). The prevalence rate for hepatitis B virus was 3.62% for tribal population and 1.17% for non-tribal population. This difference was statistically significant (p< 0.0001). Hepatitis C seropositivity was low in both groups. CONCLUSION: In Rangamati tribal population bear significantly higher burden of hepatitis B infection than non-tribal population.

Hypercalcemia in a patient with SLE and antiphospholipid antibody syndrome: a rare case report from Bangladesh
G Dewan
Journal of Universal College of Medical Sciences , 2014, DOI: 10.3126/jucms.v2i1.10490
Abstract: Association of hypercalcemia with SLE is very rare. Since initial report in 1991 only hand full cases have been described mainly in adult patients sporadically. Three pattern observed in this rare presentation. Commonly it is associated with serositis and lymphadenopathy or lymphedema known as hypercalcemia-lymphadenopathy SLE {HL-SLE) or hypercalcemia- lymphedema syndrome. Second group do not show this particular association. Concomitant primary hyperparathyroidism is responsible for third variety. This report describes a case of hypercalcemia associated with SLE from Bangladesh. DOI: http://dx.doi.org/10.3126/jucms.v2i1.10490 ?

Facies Development and Depositional Environment of the Patherwa Formation (Semri Group), Son Valley, India  [PDF]
Abul Hasnat Masood Ahmad, Ghulam Mohammad Bhat, Ruchi Agarwal
Open Journal of Geology (OJG) , 2012, DOI: 10.4236/ojg.2012.22009
Abstract: The present study documents three facies associations recorded from the Patherwa Formation. These facies are related to tidally influenced fluvial channel (Facies association A), tidal channel (Facies association B) and tidal sand bar/tidal flat sandy facies (Facies association C). The spatio-temporal variation of these facies associations and palaeocurrent trends suggest tide dominated estuarine system. The estuaries were operational along a 60 km long NW-SE trending palaeo-shoreline. The Patherwa Formation grades up-section into facies packages of increasing tidal energy and terminate with the deposition within the upper flow regime estuarine settings.
