Unfortunately, you're still vulnerable to the 200-plus other viruses floating around during any given year, Collins says, and they can combine to create more than 1,500 different variations of colds.
By comparing the results of these two sets of calculations, experimental designs were defined for air temperature treatments covering the climatic year-to-year variation of cold sum accumulation in August and September.
Ecotype specific transcripts and related gene ontology (GO) categories were identified to delineate natural variation of cold stress regulated differential gene expression in the model plant A. thaliana.
The results can be explained by the fact that a great majority of hot water usages occur during peak periods when variations of actual cold water temperature are rather small (within ± 1°C, in shaded areas of Figure 14).
Association analysis between phenotypic variations for cold stress and the SSR markers linked to candidate genes could further validate if these markers are predictive of cold tolerance in oil palm.
QTL analyses have been carried out using rice populations with large levels of genetic variation for cold tolerance (Futsuhara and Toriyama [1969]).
Natural variation for cold response and tolerance is an important element of adaptation and geographic distribution of plant species.
The cumulative occurrence of low air temperatures in August and September was quantified by calculating a cold sum for that period each year, and the climatic year-to-year variation of the cold sum accumulation was subsequently determined.
The results show that variation of the cold exit orifice hole diameter significantly influences the energy separation between two exits.
The closed-loop power law controlled system shows a much smaller variation of the cold chamber internal temperature and electrical energy consumption economy of 35.24% in comparison with the traditional on off system, under the same operating conditions.
The optimal neural model of disc brake operation has been shown to be valid for predicting the brake factor C variation of the cold disc brake over a wide range of brake's operating regimes and for different types of friction material.
