Poisoning is a global problem. Most recent estimate of World Health Organization (WHO) suggests 180 thousands deaths in 2010 due to various poisoning agents (1). Poisoning is relatively less common in children and is mostly accidental than adults. Poisoning account for 16% of bed occupancy in children hospitals and 3.9% in pediatric intensive care unit in India (2-4). Poisoning is predominantly...

Abstract- A novel low-voltage two-stage operational amplifier employing resistive biasing is presented. This amplifier implements neutralization and correction common mode stability in second stage while employs capacitive dc level shifter and coupling between two stages. The structure reduces the power consumption and increases output voltage swing. The compensation is performed by simple mill...

In this work a low power, low voltage and high gain operational amplifier is proposed. For this purpose a negative resistance structure is used in parallel with output to improve the achievable gain. Because of using self cascode transistors in the output, the proposed structure remains approximately constant in a relatively large output voltage swing causing an invariable gain. To evaluate the...

background: poison control centre of morocco (mpcc) plays a key role in promoting health. this study was aimed to demonstrate the role of the mpcc in improving public health and poisoning management. methods: this was a retrospective study of poisoning cases reported to the mpcc between 1980 and 2011. the collected data included number of poisoning cases, profession of interlocutor who called t...

OBJECTIVE The aims of this study were to (1) determine recognition of and self-reported concern regarding alcohol poisoning symptoms versus other alcohol-related behaviors among students turning 21 years old, (2) assess the frequency of helping behavior among students in situations where peers display alcohol poisoning symptoms, (3) assess sources from which students seek help, and (4) consider...

Article history: Received on: 12/12/2012 Revised on: 29/12/2012 Accepted on: 09/01/2013 Available online: 28/01/2013 Poisoning is an important public health problem causing significant morbidity and mortality throughout the world. Information available with regard to acute poisoning in adults is limited at Salem, Tamil Nadu. Hence this study was done with the above objective. It is a retrospect...

A second order switched capacitor sigma-delta modulator operating at a supply voltage of 1 V is presented. This low supply voltage restricts the gate overdrive voltage available for switching transistors. The design relies on the elimination of critical switches by using a modified switched op amp for the integrator and novel switched half-supply and reference voltage generators. The design has...

Background: Pesticide poisoning is a common method of suicide attempt and less commonly accidental poisoning in Bangladesh. This review for the first time estimated the extent and characteristics of pesticide poisoning in Bangladesh and explored existing limitations in methodologies of studies done on poisoning in the country. Methods: A narrative search in electronic medical databases includin...

Conductive and porous polythiophene (PTh) films, which are used as host matrices for Pt and Pt/Pd nanoparticles, are synthesized electrochemically. PTh films containing nanometre-sized Pt and Pt/Pd bimetallic particles are electro synthesized on an indium tin oxide (ITO) glass plate by voltammetric cycling between –0.1 to +1V (Vs Ag/AgCl / 2M NaCl). The ensuing PTh electrode, modified with nano...

We report here and experimentally demonstrate an actively controlled gate-tunable plasmonic metasurface operating in the visible region of the electromagnetic spectrum, where – strikingly – the operating voltages for reflectance modulation are much less than 1V. The electrically tunable metasurface consists of inverse dolmen structures (iDolmen) patterned on silver and chromium on a quartz subs...
