Hydrogen has the potential to be a sustainable alternative to the fossil fuels currently used in the transportation sector. The aim of our study is to appoint that producing hydrogen from biomass can be considered a green technology. There are three options for producing hydrogen from biomass. Our efforts must be focused on maximizing the reforming and shift conversions along with maximum economical...
Environmentally harmless energy sources, like hydrogen, will become important in a future sustainable system based on renewable energy. Hydrogen is an important, though little studied, trace component of the atmosphere. It is present at the mixing ratio of about 510 ppb. Hydrogen is therefore an indirect greenhouse gas with a global warming potential GWP of 5.8 over a 100-year time horizon. A future...
The aim of this study was to investigate and correlate the anatomical parameters of the superior laryngeal artery (SLA). For the study, 50 adult, human specimens were used; laryngeal pieces were drawn from 16 cadavers and the arteries were dissected intralaryngeally. In 68%, the SLA originated from the superior thyroid artery and in 32%, directly from the external carotid artery. In five sides, an...
BSP has shown that structured parallel programming is not only a performance win, but it is also a program construction win, especially if we add a formal method for designing. Maybe the most important advantage that BSP brings is the effective cost model that allows a good evaluation of the performance. The paper presents a technique for cost evaluation from specifications for BSP programs. We consider...
