In this study, five compounds, lupeol (1), epilupeol (2), β-sitosterol (3), stigmasterol (4) and p-methoxybenzaldehyde (5) were isolated from the petroleum ether and dichloromethane fractions of a methanolic extract of the stem bark of Delonix regia. Antimicrobial screening of the different extracts (15 μg mm-2) was conducted by the disc diffusion method.(More)
Bangladesh is a predominantly agricultural country containing 86,000 villages. The village population consists of mainly farmers, with the majority of them being resource-poor in the sense of having small land holdings on which they grow various crops, the major crop being paddy. Most farmers maintain one or two cows, buffaloes, or goats in their(More)
A simple spectrophotometric method is presented for the rapid determination of copper at a trace level using 2,5-dimercapto-1,3,4-thiadiazole (DMTD) as a new spectrophotometric reagent. The method is based on the reaction of non-absorbent DMTD in a slightly acidic (0.002-0.014 mol dm(-3) sulfuric acid) aqueous solution with copper(II) to produce a highly(More)
Bangladesh has been a signatory to the Convention on Biological Diversity (CBD) although implementation of the convention has been poor. We independently assessed the extent to which the program of work (POW) of the CBD has been implemented in Bangladesh by carrying out workshops involving local communities, conservation organizations, universities, and(More)
In this paper, we have focused on the view-based spatio-temporal template matching approach for human action detection and classification. We have proposed an approach for human activity modeling that describes human motions as a texture pattern. We have combined two relatively simple feature extractors for obtaining a system to get more accurate result. In(More)
Long Term Evolution (LTE) is the new standard specified by Third Generation Partnership Project (3GPP) on the way towards the 4G mobile network. The LTE introduces enhance data link mechanisms to support successful implementation of new data services across the network. The incorporated scheduling mechanisms can significantly contribute to this goal. In(More)
Telemedicine encompasses methods for electronically transmitting medical information to sustain and/or improve patient's health condition by using information and communication technology. Different countries of South Asia have tried to introduce telemedicine services from different perspectives for the rural people where health care facilities are poor(More)
This paper describes an on-line e-voting system security implementation to reduce attacks. E-voting is gaining popularity in applications that require high security. Evoting is the electronically voting process via Internet. The system represents security analysis against largescale attacks performed by rationally thinking attackers. Electronic Voting(More)
Parallel programming is becoming more and more prevalent in this era of concurrent programming. Because of the nondeterministic nature of parallel programming, it is notoriously difficult to debug concurrency bugs, moreover attempt to fix one bug may result in deadlock or other concurrency bugs. Though many static and dynamic data race detection tool is(More)
Guillain-Barré syndrome (GBS) is a post-infectious autoimmune polyneuropathy regulated by pro- and anti-inflammatory cytokines; TNFA polymorphisms may exert immune pathogenic roles in GBS. We assessed TNFA promoter region polymorphisms (-238G/A, -308G/A, -857C/T, -863C/A) in Bangladeshi patients with GBS (n=300) and healthy controls (n=300) by PCR-RFLP and(More)
