Effects of Biochar Recycling on Switchgrass Growth and Soil and Water Quality in Bioenergy Production Systems
(2012-07-16)
Intensive biomass production in emerging bioenergy systems could increase nonpoint-source sediment and nutrient losses and impair surface and groundwater quality. Recycling biochar, a charcoal byproduct from pyrolysis of ...
Regulation of the Nitrogen Fixation Genes in the Heterocystous Cyanobacterium Anabaena sp. Strain PCC 7120
(2012-02-14)
Many multicellular cyanobacteria produce specialized nitrogenfixing heterocysts. During diazotrophic growth of Anabaena (Nostoc) sp. strain PCC 7120, a regulated developmental pattern of single heterocysts separated by ...
Designing An Interplanetary Autonomous Spacecraft Navigation System Using Visible Planets
(2012-07-16)
A perfect duality exists between the problem of space-based orbit determination from line-of-sight measurements and the problem of designing an interplanetary autonomous navigation system. Mathematically, these two problems ...
Humor Alert: Muslim and Arab Stand-Up Comedy in Post-9/11 United States
(2012-07-16)
After 9/11, American stand-up comedy includes an increasing presence of Arab and Muslim comedians whose humor engages some of the recurring Islamophobic stereotypes circulating in the United States. These comedians combine ...
Coherent Control of Optical Processes in a Resonant Medium
(2012-02-14)
The resonant absorption, emission, and scattering of light are the fundamental optical processes that have been used both to probe matter and to manipulate light itself. In the last decade there has been essential progress ...
Coastal Microstructure: From Active Overturn to Fossil Turbulence
(2012-02-14)
The Remote Anthropogenic Sensing Program was a five year effort (2001- 2005) to examine subsurface phenomena related to a sewage outfall off the coast of Oahu, Hawaii. This research has implications for basic ocean ...
Evaluation of Fatigue Resistance in Alaskan Sled Dogs Through Exercise Induced Myocyte Gene Expression
(2012-02-14)
The physiological responses to exercise depend on intensity, duration, and type of exercise. The muscles in the body have complex regulation responses in order to create a certain resistance and adaptation to the exercise ...
Colon Cancer Chemoprotection through Epigenetic Effects of a Fish Oil/Pectin Diet
(2012-10-19)
Accumulated genetic and epigenetic abnormalities contribute to the development of colon cancer. We have shown that a combination of fish oil (containing decosahexaenoic acid, DHA, 22:6 n-3) and pectin (fermented to butyrate ...
Nutritional Contribution of Phytoplankton to the Pacific White Shrimp Litopenaeus vannamei
(2012-07-16)
The goal of this study was to characterize the nutritional contribution of microalgae to white-legged shrimp and optimize fish meal (FM) and fish oil (FO) inclusion levels in their diets in the presence of microalgae. ...
Reconstruction of Early Paleogene North Pacific Deep-Water Circulation using the Neodymium Isotopic Composition of Fossil Fish Debris
(2012-10-19)
To better understand the operating mode of the deep oceans during fundamentally warm climate intervals, we present new Nd isotope data from Deep Sea Drilling Project and Ocean Drilling Program sites in the North Pacific ...
