n engl j med 360;7 nejm.org february 12, 2009 653 fees.1 Congress appropriately feared the potential problems with access to care that could result from such a fee reduction. But although putting more money into the same broken physician-reimbursement system may buy lawmakers a little more time to address the need for a new one — helpful only if they use it to set the direction for a new system...

Trade Performance Depends on Bold Reform. The comparative study of What's inside ... he radical transformations of the fifteen countries of the former Soviet Union (FSU), along with those of the transition economies of Eastern Europe, are producing demographic trends never before seen in developed countries. These include declining birth rates in all fifteen countries, plunging some of them to ...

“Architecture” may seem a rather pretentious word to describe the ad hoc set of arrangements that make up the current international financial system . Even a reformed financial system will surely lack the clarity of structure and design that are the hallmarks of good architecture . But a financial system should nevertheless conform to certain broad principles, which can be readily understood an...

Many countries are in the earliest stage of reforming the care sector. Reformers face challenges as they develop public policy to expand family based care and shrink institutional care. To mention a few: installing the keystone component of care reform - a system to monitor and support children post-institutionalization; enabling children to grow up where they belong, in families; meeting child...

Direct internal reforming in solid oxide fuel cell (SOFC) results in increased overall efficiency of the system. Present study focus on the chemical and electrochemical process in an internally reforming anode supported SOFC button cell running on humidified CH4 (3% H2O). The computational approach employs a detailed multi-step model for heterogeneous chemistry in the anode, modified Butler–Vol...

The activity of Ni supported on mesoporous SBA-15, MCM-41, KIT-6, and a sol-gel prepared Ni/γAl2O3, for catalysing methane dry reforming was investigated. The chemical and physical characteristics of the catalysts before and after catalytic testing were investigated using X-Ray diffraction, X-ray Photoemission Spectroscopy, Transmission Electron Microscopy, Scanning Electron Microscopy / Energy...

A highly active and stable nano structured Pt/Mg1-xNixO catalysts was developed by a simple co-precipitation method. The obtained Pt/Mg1-xNixO catalyst exhibited cubic structure nanocatalyst with a size of 50-80 nm and realized CH4 and CO2 conversions as high as 98% at 900°C with excellent stability in the dry reforming of methane. The characterization of catalyst was performed using various ki...

A detailed study on the preparation of bimetallic PtSn/C catalysts using surface-controlled synthesis methods, and on their catalytic performance in the glycerol steam reforming reaction has been carried out. In order to obtain these well-defined bimetallic phases, techniques derived from Surface Organometallic Chemistry on Metals (SOMC/M) were used. The preparation process involved the reactio...

An experimental and kinetic modeling study on the Ni-catalyzed conversion of methane under oxidative and reforming conditions is presented. The numerical model is based on a surface reaction mechanism consisting of 52 elementary-step like reactions with 14 surface and six gas-phase species. Reactions for the conversion of methane with oxygen, steam, and CO2 as well as methanation, water-gas shi...

Synthesis gas manufacturing by steam reforming of hydrocarbons is an important industrial process. High endothermic nature of the process makes it one of the most cost and heat intensive processes. In the present work, composite effect of different inert gases on synthesis gas yield, feed gas conversion and temperature distribution along the reactor length has been studied using a heterogeneous...
