OBJECTIVE To investigate the long-term impact of health education in intestinal helminth infection control in rural Bangladesh. STUDY DESIGN Longitudinal study to compare knowledge, awareness and practice for intestinal helminths between four communities: two receiving health education and two not receiving health education. METHODS Parents of 1497(More)
BACKGROUND Tobacco smoking issues in developing countries are usually taught non-systematically as and when the topic arose. The World Health Organisation and Global Health Professional Student Survey (GHPSS) have suggested introducing a separate integrated tobacco module into medical school curricula. Our aim was to assess medical students' tobacco smoking(More)
OBJECTIVES To determine the extent of all forms of tobacco usage in adult Bangladeshis in relation to gender and locality. METHODS Three annual urban and rural cross-sectional surveys were carried out between 2001 and 2003 involving a total of 35,446 adults, of whom 54.3% were female and 51.0% were rural dwellers. Data were collected through interview(More)
BACKGROUND To estimate the amount of regret and weights of harm by omission and commission during therapeutic decisions for smear-negative pulmonary Tuberculosis. METHODS An interviewer-administered survey was done among young physicians in India, Pakistan and Bangladesh with a previously used questionnaire. The physicians were asked to estimate(More)
BACKGROUND Thrombus formed in blood vessels lead to atherothrombotic diseases such as myocardial or cerebral infarction. Thrombolytic agents are used to dissolve the already formed clots in the blood vessels; however, these drugs sometimes cause serious and fatal consequences. Herbal preparations have been used since ancient times for the treatment of(More)
Wireless sensor networks (WSNs) face significant scalability challenges due to the proliferation of wide-area wireless monitoring and control systems that require thousands of sensors to be connected over long distances. Due to their short communication range, existing WSN technologies such as those based on IEEE 802.15.4 form many-hop mesh networks(More)

Interference between concurrent transmissions causes severe performance degradation in a wireless network. This paper addresses interference cancellation to enable simultaneous packet receptions at a node with a single radio in Wireless Sensor Networks (WSN). Interference cancellation is particularly important for WSN as most of its applications rely on(More)
Accessibility problems such as obstacles on sidewalks can make navigation dangerous for the visually impaired. Detecting these accessibility problems using embedded cameras is a plausible remedy. However, current computer vision algorithms for object detection rely on exhaustive search with high-dimensional features that present a heavy computational burden(More)
