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.
Detection of Mechanical Deformation in Old Aged Power Transformer Using Cross Correlation Co-Efficient Analysis Method  [PDF]
Asif Islam, Shahidul Islam Khan, Aminul Hoque
Energy and Power Engineering (EPE) , 2011, DOI: 10.4236/epe.2011.34073
Abstract: Detection of minor faults in power transformer active part is essential because minor faults may develop and lead to major faults and finally irretrievable damages occur. Sweep Frequency Response Analysis (SFRA) is an effective low-voltage, off-line diagnostic tool used for finding out any possible winding displacement or mechanical deterioration inside the Transformer, due to large electromechanical forces occurring from the fault currents or due to Transformer transportation and relocation. In this method, the frequency response of a transformer is taken both at manufacturing industry and concern site. Then both the response is compared to predict the fault taken place in active part. But in old aged transformers, the primary reference response is unavailable. So Cross Correlation Co-Efficient (CCF) measurement technique can be a vital process for fault detection in these transformers. In this paper, theoretical background of SFRA technique has been elaborated and through several case studies, the effectiveness of CCF parameter for fault detection has been represented.
Measurement of Signal Strength in CDMA by Simulation of Power Losses Estimation
Muhammad Rezaul Hoque Khan
Asian Journal of Information Technology , 2012,
Abstract: CDMA (Code Division Multiple Access) combines multiple signals and improves signal strength. This leads to the near elimination of interference and fading. Both electrical background noise (computer noise) and acoustic background noise (background conversations) are filtered out by using narrow bandwidth, which corresponds to the frequency of the human voice. This keeps background noise out of our conversations. In this paper a simulation of power lossess estimation is compared with real measurements. The field strength at corner points of each cell is calculated using modified Hata model based on reference regarding the antenna heights of the base station and mobile station at 30 and 1.5 meters and the antenna gain of the base station and mobile station at 17 dB and 0 dB respectively. Results obtained are compared with those of predicted by Citycell Digital, only CDMA operator in Bangladesh, first to adopt CDMA technology in the sub-continent. In this paper the experimental data collected through the area of coverage in different cases.

Open Journal of Preventive Medicine (OJPM) , 2012, DOI: 10.4236/ojpm.2012.23055
Abstract: The concept of fecundability derives its importance for the study of human fertility from the fact that it is one of the principal determinants of fertility and is a major standard by which the impact of fertility regulation can be assessed; very few attempts have been made in Bangladesh for estimating fecundability. This study attempts to evaluate the levels, patterns, and trends of fecundability and identify the factors affecting fecundability in Bangladesh based on national surveys of Bangladesh Demographic and Health Survey (BDHS) 2007-1994. Total 9703 ever married women are included in the bivariate and multivariate analyses which reveal that age at first birth, age at marriage and marital duration play an important role in influencing marriage to first birth interval positively and thus fecundability negatively. Although fecundability in Bangladesh showed an increasing trend, but it is very low compared to developed and developing countries.

Asian Journal of Plant Sciences , 2003,
Abstract: An experiment was conducted at the Agronomy Field Laboratory, BAU, Mymensingh during June to December 2000 to assess the effect of varieties of transplanted aman rice and weeding regimes on weed growth and yield of transplant aman rice. Five varieties and five weeding were used in the experiment. The results revealed that BRRI dhan 34 was the most competitive variety, which provided with the least accumulation of weed dry matter per unit area. The ranking was BRRI dhan 34 =Binashail > Nizershail > BRRI dhan 39 =BRRI dhan 33 The ranking of the varieties in respect of grain yield was BRRI dhan 39 =BRRI dhan 33 > Binashail > BRRI dhan 34 > Nizershail. The effect of weeding regimes produced significant differences on the weed growth and grain yield of transplant aman rice. The reduction of weed dry matter was similar in both two weeding and three weeding regimes. The highest grain yield was noted under three weeding conditions (3.95 t ha-1) which was at par with weed free (4.01 t ha-1), but dissimilar to two weeding regimes (3.71 t ha-1).
A New Surgical Technique of Biliary Drainage  [PDF]
Shafiqul Hoque
International Journal of Clinical Medicine (IJCM) , 2013, DOI: 10.4236/ijcm.2013.49072
Abstract: Introduction: Roux-en-Y Hepatico-jejunostomy is the standard technique of biliary reconstruction after excision of choledochal cyst. Here the author describes a new surgical technique of biliary reconstruction using native gall bladder as biliary conduit. New Surgical Technique: The choledochal cyst is excised as standard technique but gall bladder with its neck is kept in situ. The gall bladder neck is anastomosed with the common hepatic duct stump and gall bladder fundus is anastomosed with the antero-inferior wall of the first part of distal duodenum. Materials & Methods: Eleven patients with choledochal cyst have been operated with the new technique from July 2011 to December 2012 in the city of Dhaka, Bangladesh. Feeding was started from 3rd post-operative day and drain was removed by 7th day unless complicated and they were released from the hospital between 10-15 days. Results: The ages of eleven patients were from 3 months to 11 years. There were 7 females and 4 males. Lump was felt in 3 patients and jaundice was present in 4 patients. Recurrent abdominal pain was present in all patients. They were diagnosed by ultrasonography and MRCP was done in 6 patients only. Prothrombin time was elevated by 10% & 15% in 2 patients. Average operation time was 2 hours and 10 minutes. A 9-year girl died suddenly and unexpectedly on the 5th post-operative day from severe convulsion of unknown origin. One child suffered from prolonged bile leakage and re-explored to repair anastomotic leak. Another patient had a collection near the anastomosis which resolved spontaneously. Discussion: Benefits of the new surgical technique are total absence of Roux-en-Y related intestinal complications. Possible disadvantages are discussed. It is anatomical and physiological. Small incision and less operation time are other benefits which need to be mentioned. Possible disadvantages are discussed.

Abstract: In-vitro callus induction and regeneration method was developed using different plant growth regulators (PGRs), and basal media (Murashige and Skoog (MS), CHU (N6) and Gamborg (B5) media) of Citrus sinensis (L.) Osbeck. Observations of the effect of PGRs were carried out using different concentrations of 2,4-dichlorophenoxyacetic acid (2,4-D),1-naphthalene acetic acid (NAA) and combinations of 2,4-D and NAA using different basal media. This study found Citrus sinensis (L.) Osbeck exhibited a high frequency of callus induction on MS medium supplemented with 3 mg/L 2,4-D and callus induction frequency was 86.7% ± 3.4% whereas N6 and B5 showed lower callus induction frequency of 83.3% ± 8.8% and 82.2% ± 1.9% respectively

Lourdes DelRosso, Romy Hoque
Case Reports in Clinical Medicine (CRCM) , 2012, DOI: 10.4236/crcm.2012.11001
Abstract: We present a 4-year-old girl with allergies and asthma who developed night terrors after initia- tion of montelukast at 2 years of age. Montelu-kast was discontinued and cetirizine was started. Nigh terrors persisted. Sleep diaries were col- lected and diagnosticpolysomnogram (PSG) was ordered. Sleep diaries revealed an average sleep time of 10 hours with night terrors occur- ring three nights a week approximately two hours after sleep onset. The PSG did not show evidence of sleep disordered breathing or peri- odic leg movements. Cetirizine was discontin- ued and the night terrors ceased. Upon re-intro- duction of the medication, the sleep terrors re- curred.
