Heat removing under hypersonic conditions

Differential gene expression in Festuca under heat stress conditions.

Fescues (Festuca sp.) are major cool-season forage and turf grass species around the world. Heat stress is one of the limiting factors in the production of fescues as forage in the southern Great Plains of the US. Heat responsive gene transcripts were cloned by using suppression subtractive hybridization between a heat-tolerant and a heat-sensitive fescue genotype subjected to a slowly increase...

Convective Heat Transfer of Binary Mixtures under Flow Boiling Conditions

The present study represents part of an effort in considering the replacement of ethylene-glycol/water mixtures with propyleneglycol/water mixtures for engine cooling in automotive application. Experimental results are presented for the heat transfer coeffic ient under flow boiling conditions for water and mixtures of water with ethylene-glycol and propylene-glycol. The range covered includes t...

Water Salinity Under Heat Stress in Grazing Conditions

Metabolic Heat Production by Artemia Embryos under Anoxic Conditions

The metabolic status of encysted Artemia embryos under anoxic conditions has been studied by calorimetry. Previous work demonstrated a very low, but still measurable, source of metabolic heat (31nWmg21 drymass) after 6 days of anoxia, attributed to the catabolism of small amounts of carbohydrate storage compounds and the unusual nucleotide diguanosine tetraphosphate. Our results indicate that t...

Rubisco activase and wheat productivity under heat-stress conditions.

Rubisco activase (RCA) constrains the photosynthetic potential of plants at high temperatures (heat stress). Endogenous levels of RCA could serve as an important determinant of plant productivity under heat-stress conditions. Thus, in this study, the possible relationship between expression levels of RCA and plant yield in 11 European cultivars of winter wheat following prolonged exposure to he...
