The acceptance of public participation in science and technology governance in liberal democratic contexts is evident in the institutionalization of a variety of mechanisms for participation in recent decades. Yet questions remain about the extent to which institutions have actually transformed their policy practice to embrace democratic governance of techno-scientific decision making. A critic...

hirchsprung’s disease is a developmental disorder of the enteric nervous system, characterized by abdsence of ganglion cell in the myenterric and submucosal plexuese along a variable portion of the distal intestine.the purpose of this study is the presentation of a new procedure for reduction of the postoperative complications of hirschsprung’s disease (hd) by offering a modified swenson’s tech...

background: visceral leishmaniasis is systematic serous parasitic disease with pub­lic health importance. zoonotic form of visceral leishmaniasis is wide spread in mediterranean basin and south america regions. direct agglutination test (dat) is an accurate, reliable and non-expensive serological test for the diagnosis of visceral leishmaniasis in human and canines but the antigen preparation i...

chromium (vi) adsorption behavior and capacity by surface modified nanozeolite a has been investigated. surface modification was performed and the morphology of modified and unmodified nanozeolite was studied using scanning electron microscope (sem) and transmission electron microscope (tem). adsorption isotherms were studied under different conditions (ph, adsorbent dose, adsorbate concentrati...

this paper provides an overview of how the surface properties of ferromagnetic nanoparticles dispersed in fluids is modified by natural and biocompatible polymers. among common magnetic nanoparticles, magnetite (fe3o4) and maghemite (g-fe203) are popular candidates because of their biocompatibility. natural polymeric coating materials are the most commonly used biocompatible magnetic nanopartic...

OBJECTIVE To conduct a clinical and economic evaluation of outpatient weight loss strategies in overweight and obese adult U.S. women. RESEARCH METHODS AND PROCEDURES This study was a lifetime cost-use analysis from a societal perspective, using a first-order Monte Carlo simulation. Strategies included routine primary care and varying combinations of diet, exercise, behavior modification, and...

The potential to reduce cardiovascular morbidity through dietary modification remains an area of intense clinical and scientific interest. Any putatively beneficial intervention should be tested within a randomised controlled trial which records appropriate endpoints, ideally incident CVD and death. However, the large sample sizes required for these endpoints and associated high costs mean that...

Recognizing that: • The global burden of maternal and child undernutrition remains unconscionably large, and is the single greatest constraint facing global development efforts. • A renewed and strengthened evidence base exists for a set of essential nutrition interventions that if effectively targeted to mothers and children from conception to two years of age, could prevent at least a quarter...

BACKGROUND An independent Systematic Review Team performed a meta-analysis of 12 randomized, controlled trials comparing multiple micronutrients with daily iron-folic acid supplementation during pregnancy. OBJECTIVE To provide an independent interpretation of the policy and program implications of the results of the meta-analysis. METHODS A group of policy and program experts performed an i...

Currently, carbide cutting tools are mainly used for processing blanks of machine parts. Increasing the working life plates is one urgent tasks in mechanical engineering. The paper proposes to increase due complex modification surfaces tool. Modification tool surface proposed be carried out on basis electron beam alloying with an alloy based niobium and hafnium, followed by application a wear-r...
