Acorn Contribution to Mammalian Energetics
Acorns are a highly nutritious food source for many mammal species including white-tailed deer (Odocoileus virginianus), white-footed mice (Peromyscus leucopus), eastern gray squirrels (Sciurus carolinenis), and fox squirrels (S. niger). Oak trees (genus (Quercus) produce variable amounts of acorn …

Swimming behavior and energetics of sharks
In a field study of blue shark swimming behavior, acoustic telemetry was used to record depth, swimming speed and tailbeat frequency from free-ranging blue sharks (Prionace glauca) in northwestern Atlantic slope waters. Records obtained from five sharks show a consistent pattern of vertical …

DISTRIBUTED ENERGETICS OF BOREAL FOREST SNOWMELT
The energetics of snowmelt under boreal forest canopies in central Saskatchewan were examined with respect to the influence of forest canopy structure on the snow cover depletionrate. The distribution of snow water equivalent was examined prior to melt and during melt in five distinct boreal forest …

Energetics of neutral interstitials in germanium
Significant obstacles remain for the fabrication of germanium n-MOSFETs, including enhanced diffusion of donor atoms which leads to electrical deactivation. The preferential generation of self-interstitials via proton irradiation reduces donor diffusion and offers a promising route for effective …

Role of pavements in urban energetics
… which can be described as the study of urban energetics. The term ’microscale UHI’ is adopted to highlight this difference and is studied in terms of differences in air temperature at 2 m height averaged over an hour of the day. To determine the contribution of pavements to the development of …

Energetics of substrate unfolding by ClpA
… The goal of this work is to describe the energetics of ClpA's interactions with both soluble and membrane-bound protein substrates. Green fluorescent protein modified with an 11-amino acid tag that facilitates ClpA recognition (GFP-ssrA) is used as a model soluble substrate, and …

Energetics of low-input corn production
… nitrogen-fixing legume production and use. The energetics of com silage and com grain production under standard and alternative practices are examined. Economic analyses of crop production practices are used to aid the selection of recommended alternative practices. In corn silage production, …

Instability and energetics in a baroclinic ocean
This thesis is made of two separate, but interrelated parts. In Part I the instability of a baroclinic Rossby wave in a two-layer ocean of inviscid fluid without topography, is investigated and its results are applied in the ocean. The velocity field of the basic state (the wave) is characterized …

Movement and energetics of swimming marine mollusks
Mollusks constitute a significant proportion of marine animal biomass and fulfill essential ecosystem functions. Yet, our knowledge of their behavior and energy output in natural environments remains elusive. This key knowledge gap stems from our inability to quantify their positions and movements …

Extracellular Metabolic Energetics Can Promote Cancer Progression
… modulation of intra- and extracellular energetics by colon cancer cells that contributed to colon cancer cell survival in the liver microenvironment, allowing for development of macrometastases and finally liver colonization. Further investigation identified the membrane transporter …

Towards Improved Estimates of Upper Ocean Energetics
<p>The energy exchanged between the atmosphere and the ocean is an important parameter in understanding the Earth’s climate. One way of quantifying this energy exchange is through the use of “wind work,” or the work done on the ocean by the wind. Since wind work is calculated according to the …

Energetics and mixing in stratified turbulent flows
Turbulent mixing has an important influence on many physical processes in the ocean. For example, the upwelling of water through the stably stratified ocean interior, needed to close the global circulation, is only possible through the enhanced vertical mixing resulting from turbulence. The …

Optimal workloop energetics of muscle-actuated systems
… study the role of muscle co-activation from an energetics perspective: Are there situations in which antagonist co-activation leads to enhanced power generation, and if so, what is the underlying mechanism? The mechanical energetics of muscles are traditionally characterized in terms of workloop …

Energetics of a sustainable crop-livestock system
… one kilogram of baled hay. To compare the energetics of the two systems on a whole farm basis, the amount of energy required to produce one dollar of return was calculated. The sustainable system required 12.4 megajoules to produce one dollar of return, while the conventional system …

Modeling the Energetics of the Upper Atmosphere
… we also develop the Atmospheric Chemistry and Energetics (ACE) 1D model using up-to-date aeronomic results. The model self-consistently solves the 1D momentum and energy equations to produce a global average profile of the coupled thermosphere and ionosphere system in terms of its constituent …
