mergency care is important to me for lots of reasons, but for one in particular: it's important to patients. We know that A&E services—and by implication all the components that make up the whole emergency care system—are among patients' top concerns. Within A&E I believe a critical concern for patients is how long they have to wait for clinical care, and I can't blame them. When you are in pai...

There are three main areas of our federal system that need reform. The first is the allocation of powers and functions between the levels of government. The allocation made by the framers of the Constitution in the 1890s may no longer be appropriate today. Many of the complaints of unnecessary duplication, cost-shifting and lack of coordination can be traced back to the absence of clear divisio...

in this paper, using a one-dimensional simulation model, the reforming process of sour gas, i.e. ch4, co2, and h2s, to the various charged particles and syngas in a dielectric barrier discharge (dbd) reactor is studied. an electric field is applied across the reactor radius, and thus a non-thermal plasma discharge is formed within the reactor. based on the space-time coupled finite element meth...

methanol steam reforming plays a pivotal role to produce hydrogen for fuel cell systems in a low temperature range. to accomplish higher methanol conversion and lower co production, the reaction was catalyzed by cuznfe mixed oxides. various ratios of fe and cu/zn were coprecipitated in differential method to optimize the cuznfe structure. the sample containing 45cu50zn5fe (wt. %) revealed its m...

a micro-channel heat exchanger reactor with different micro-baffle shapes has been studied numerically. governing equations were solved base on the finite volume method with fluent software. in upper section, oxidation reaction of methanol was occurred and in lower section, steam reforming of methanol was done. two sections were separated with solid part which played as heat exchanger and trans...

In this report, we introduce a novel and commercially viable method to recover renewable hydrogen and carbon nanotubes from waste glycerol produced in the biodiesel process. Gas-phase catalytic reforming converts glycerol to clean hydrogen fuel and by replacing the problematical coke formed on the catalyst with high value carbon nanotubes, added value can be realised. Additional benefits of aro...

this paper aims to show the impact of fear of god, as one of the most important signs of religious spirituality, on improving sexual and gender relationships in family and society as well as other social relationships and thus to offer some procedures for enhancing and expanding this character at familial and societal levels in order to reduce the problems involved in social relations specially...

A compact reformer to generate hydrogen for portable fuel cell applications is presented. This reformer is a conventional type single-path tubular reactor packed with granular catalyst particles in which steam reforming and catalytic partial oxidation reactions take place in series using a mixture of methanol and water as a feed. The novel feature of this reformer is in the interlacing of the f...

A detailed model is presented for the analysis of temperature, species concentration, and current density profiles as well as the efficiency and power density of a planar solid oxide fuel cell at direct internal reforming condition. The model describes the interactions of mass transport, heat transport, heterogeneous chemistry, and electrochemistry. The heterogeneous chemistry model for the cat...

The high efficiency and energy density of miniaturized fuel cells provide an attractive alternative to batteries in the portablepower-generation market for consumer and military electronic devices [1-3]. The best fuel cell efficiency is typically achieved with hydrogen, but safety and reliability issues remain with current storage options. Consequently, there is continued interest in reforming ...
