An analysis of water consumption rates in agricultural irrigation systems
… background for the discussion of the high water consumption rates found in irrigation systems which use projectile-type sprinkler heads, the history and evolution of irrigation systems is discussed. The effect of evaporation is studied as as explanation for the water losses, but it is found to be …

Abrasive Blasting Process Optimization: Enhancing Productivity, and Reducing Consumption and Solid/Hazardous Wastes
… establishing relationships between applied feed rates and resulting productivity and consumption rates. It is clear that the high costs of disposal of the multimedia wastes generated by the dry abrasive blasting processes are of increasing concern in the future of shipbuilding industry. In such …

Air Consumption and Air Management in the Fire Service
… difference between various factors affecting air consumption rates and air management in the fire service. The purpose was to develop a better understanding of what had the most significant effect on air consumption rates in order to develop a point of focus so that fire departments could …

The behavioral physiology of labroid fishes
… torpor, or hibernation, based on low oxygen consumption rates in winter, contributing to a large Q10 value of 8.5. It is thus established as one of the few marine species that is known to hibernate. Cunner withstood four months of starvation at 4°C. Glycogen, lipid, and protein in the liver …

Responses to salinity of color polymorphs in two populations of the sea star, Pisaster achraceus
… 30, and 40 psu).</p> <p>Wet mass-specific oxygen consumption rates were not significantly affected by color, location, or salinity, and Dry mass-specific oxygen consumption rates showed no significant differences for main effects, but a three-way interaction was identified. Similarly, ammonia …

Biochemical Thermodynamic Modelling of Cellular Bioenergetics: A Quantitative Systems Pharmacology Approach
… bioenergetics, capable of simulating oxygen consumption rates of a cohort of in vitro human primary hepatocyte data. The model is finally used to simulate perturbations in key bioenergetic variables and reaction fluxes, illustrating the resulting changes on mitochondrial pH, membrane …

Effects of Temperature on Winter Energetics of Female Indiana Bats (Myotis Sodalis)
… at 9°, 7°, 5°, 3°, and 1°C to calculate oxygen consumption during torpor, and during arousals at 9°, 7°, 5°, and 3°C. Torpid metabolism was affected by temperature; particularly, torpor metabolism at 9°C was higher than at 7° or 5°C. Although metabolism for arousals was not different among …

Aspects of the respiratory metabolism of juvenile rainbow trout (Oncorhynchus mykiss) at sustained swimming speeds
… detectable diurnal variation in the respiration rates of juvenile rainbow trout. Experiments investigating aerobic energy expenditure at sustained swimming speeds, through measurements of oxygen consumption rates, are described. Oxygen consumption was found to increase exponentially with …

Effects of zinc and mercury on the white shrimp, Penaeus setiferus
… of locomotor activity, mortality, and oxygen consumption. Four-day mortality results (the number or percentage dead) allowed reasonable conclusions concerning zinc and mercury toxicity, but other methods of expressing data yielded additional information. Expressing mortality (time to death for …

Modeling oxygen requirements in ischemic cardiomyocytes
… and compare these conditions to baseline energy consumption rates. Glycolytic metabolism is modeled using a system of coupled ordinary differential equations that describe the individual metabolic reactions that occur within the cardiac myocyte and its surrounding tissue. Over 200 conditions were …

Determinants and Developmental Consequences of Organic Contaminant Uptake in Nestling Insectivorous Birds
… each population were analyzed. Nestlings’ growth rates were measured in the field from which values consumption rates were estimated. Contamination loads were estimated by multiplying consumption rates by food-specific contaminant concentrations and combined with egg-acquired burdens in a …

Energetic costs of toxicant metabolism in rainbow trout ( Oncorhynchus mykiss)
… metabolism was measured as changes in oxygen consumption rates and changes in plasma glucose and triglyceride concentrations as well as liver glycogen. PCB-126 and BNF treatments resulted in significant changes in metabolic parameters. Treatments with RVT were inconclusive. Although results …

The Effects of Seasonal Changes and Turbidity on Swimming Performance in White Crappie Pomoxis Annularis and Black Crappie Pomoxis Nigromaculatus.
… displayed a significant increase in oxygen consumption in response to elevated turbidity. There were no differences in oxygen consumption rates between the two species within any of the four seasons or at the three levels of turbidity tested.

Predicting the impact of future climate on ecologically important macroalgae
… and chemical performance of macroalgae and the consumption rates of associated herbivores. Many studies have focused on ocean acidification or ocean warming individually but there is an overall lack of research investigating the combined effects and the ensuing repercussions on consumer-prey …
