Female aspic vipers (Vipera aspis) are ‘‘capital breeders,’’ and delay reproduction until they have amassed large energy reserves. Data from an eight-year mark– recapture study on free-ranging vipers suggest that potential costs of reproduction were high for these animals, in terms of survival as well as growth and energy storage. Females that reproduced experienced higher mortality rates than ...

due to increasingly expansion of energy consumption and also decreasing and tendency towardsending fossil energy reserves, the current energy cycle needs to use alternative energy speciallywind energy, because it’s considerably cheaper than other recycling sources. the present researchinvestigates possibility of creating wind power station economically at soltanieh zone of zanajnprovince regard...

The volatility of oil prices has increased visibly in the last decade. Undoubtedly, occurrence affects economics exporting and importing differently. Increases positively affect economic indicators economies, while decreases have negative effects. In this regard, increases attracted researchers’ attention, a vast literature is found investigating both countries as well advanced emerging market ...

a r t i c l e i n f o JEL classifications: G34 L71 M20 Keywords: Takeovers Mergers & acquisitions Oil and gas industry Oil reserves Energy Can broad factors such as natural resources endowment and global commodity markets influence corporate takeovers? This paper theorizes that managers are motivated in mergers and acquisitions to purchase energy reserves and to time the commodity market in the...

where he is also Director of the Center for the Environment. He currently serves on President Obama's Council of Advisors on Science and Technology. He has authored more than one hundred articles on topics in geochemistry, geology, paleoclimatology, ocean-ography, energy technology, and energy policy. Over the last ten years, technological innovation has transformed U.S. energy resources. Geolo...

This study evaluates the influence of different states of energy balance, positive and negative, on the accumulation and utilisation of energy reserves during the period of gonad development in the clam Ruditapes decussatus (L.). Our results show a clear sexual differentiation in the biochemical composition of the clams. The differences were associated with gonad development and were particular...

Wind power generation is variable and uncertain. In the power systems with high penetration of wind power, determination of equivalent operating reserve is the main concern of systems operator. In this paper, a model is proposed to determine operating reserves in simultaneous market clearing of energy and reserve by stochastic programming based on scenarios generated via Monte Carlo simulation ...

Understanding how environmental temperature affects metabolic and physiological functions is of crucial importance to assess the impacts of climate change on organisms. Here, we used different laboratory strains and a wild-caught population of the fruit fly Drosophila melanogaster to examine the effect of temperature on the body energy reserves of an ectothermic organism. We found that permanen...

in this study, the energy reserves of prediapause and diapausing adult bugs were examined using colorimetric biochemical techniques to determine carbohydrates, lipids, glycogen, and protein content. to this end, 45-day-old bugs were obtained from three different sources: laboratory colony, cold-stored insects, or natural habitat. the results showed that prediapause males and females had signifi...
