Flame stability in a lean fuel-air mixture is studied experimentally in a metal–ceramic porous burner. Ceramic medium with small pore diameter is inserted on the metal porous medium in order to prevent flame blow off. Position of the flame is obtained with the measured temperature profile in the sidewalls of the burner. Temperature profiles are obtained at different firing rates and equivalence...
of overlapping interests. Put them in a good physical plant with lots of shared space, and let them go to it. When it comes to the size of individual research groups, there’s a value-formoney issue too — we are mostly spending the taxpayers’ coin, after all. I have always had the impression that individual laboratory groups larger than about a dozen full-time workers produce less science per do...
managed to lure chemical geneticist Guri Giaever away from Stanford University two years ago, part of the inducement was a new, bigger lab, and part was a prestigious government-funded research chair. But the biggest factor in the move, Giaever says, was the colleagues with whom she would be working. “In terms of what I’m doing, I would pretty much say hands down that Toronto is the best place ...
Infertility affects both men and women. Literature suggests that disorders in males and females account for an equal proportion of infertility [1]. Concerns have been expressed about rising cases of male infertility [3]. This can be as a result of congenital and acquired urogenital abnormalities, infections of the genital tract, increased scrotal temperature (varicocele), endocrine disturbances...
In the article, the authors analyse features of aluminium, which are important for the noncontact measurement of the temperature. This study is based on the results of experiments, which were carried out at foreign research institutes. Rising interest of the industry in contactless measurement of foamy aluminium profiles during their production was the motivation for this article.
The interaction between flowers and insect pollinators is an important aspect of the reproductive mechanisms of many plant species. Several laboratory and field studies indicate that raising flower temperature above ambient can be an advantage in attracting pollinators. Here we demonstrate that this preference for warmer flowers is, in fact, context-dependent. Using an Australian native bee as ...
Heat injury is a problem for the Armed Forces, especially during deployment to localities with very hot and humid climates. Early warning of a rising core body temperature (TC) can help prevent heat injuries. To this end, we developed an algorithm that, given a series of past TC measurements obtained using an ingestible temperature pill, accumulates evidence of a rising TC over time and provide...
in the presented research, heat transfer of a mobile electrolyte alkaline fuel cell (afc) (which the electrolyte has cooling role of system) has been considered. proper control volumes of system with specific qualification have been chosen. consequently, heat and mass transfer in control volumes have been assessed. considerations on them and contributed models lead to approve a double tube heat...
weather condition is one of the much effective factors in the principle of architecture and urbanization. so in this research long-term trend of effective climate elements in architecture of darab city including mean of minimum temperature, temperature mean, mean of maximum temperature, minimum relative humidity, maximum relative humidity, relative humidity mean, wind speed and sun hours in mon...
