Recent data underscore the importance of intertissue communication in the maintenance of normal glucose homeostasis. Important signals are conveyed by hormones, cytokines, and fuel substrates and are sensed through a variety of cellular mechanisms. The ability of tissues to sense and adapt to changes in metabolic status and fuel availability is altered in insulin-resistant states including type...

To help understand the complex fuel spray combustion phenomena in modern diesel engine using high injection pressure, a fuel injection test bench and a constant volume combustion chamber were developed and demonstrated in this study for diesel spray diagnostics. Both facilities are significant when linking between spray injection and combustion dynamics and engine performance. This link is impo...

In cold-exposed adult humans, significant or lethal decreases in body temperature are delayed by reducing heat loss via peripheral vasoconstriction and by increasing rates of heat production via shivering thermogenesis. This brief review focuses on the mechanisms of fuel selection responsible for sustaining long-term shivering thermogenesis. It provides evidence to explain large discrepancies i...

One half of the world's population relies on biomass fuel as the primary source of domestic energy. Biomass fuel exposure causes a high degree of morbidity and mortality in humans. This is especially true in the context of developing countries, which account for 99% of the world's biomass fuel use. Biomass fuel consists of fire wood, dung cakes, agricultural crop residues such as straw, grass, ...

Previous Advanced Fuel Cycle Initiative (AFCI) studies were made to assess the effects of the existing accumulation of LWR spent fuel in the United States on the capability to partition/transmute actinides using existing and advanced LWRs. The concept of treating the “oldest fuel first” indicated that significant advantages could be gained in both partitioning, transmutation, and in overall cos...

This paper presents a new type of eddy current transducer, send-receiver type, using the rotating magnetic field method. The forward problem was solved, the experimental results obtained for detection of different types of degradation have proved the capability to emphasize blisters, and garter springs location and tilt as well as hydrogen content. INTRODUCTION The nondestructive testing of met...

Peatlands represent a globally important carbon store; however, the human exploitation of this ecosystem is increasing both the frequency and severity of fires on drained peatlands. Yet, the interactions between the hydrological conditions (ecotopes), the fuel types being burned, the burn severity, and the charring temperatures (pyrolysis intensity) remain poorly understood. Here we present a p...

purpose: the purpose of this paper is to evaluate to what extent the construction of common and individual biogas plants can answer the fuel needs of rural people or families. methodology: the present study with descriptive - analytical method, examines the fuel needs of the rural people and its supply by biogas from livestock waste. findings: the primary outcome of the proportion of rural popu...
