The National Science Foundation (NSF) and the U.S. Department of Agriculture's (USDA) National Institute of Food and Agriculture (NIFA) have issued 27 research project awards, totaling more than $18 m...
The purpose of the present study was to determine whether any relationships were present between lower-body muscle structure and, lower-body strength, variables measured during a countermovement jump ...
Strong earthquakes can trigger several phenomena inducing soil deformation, such as liquefaction, ground fracturing and landslides, which can often cause more damage than the seismic shaking itself. A...
The sudden event of the spread of dengue fever (or break-bone fever) that appeared for the first time in Cape Verde in 2009 revealed that inappropriate management of waste can be considered a major ca...
Shear wave velocity, Vs, is one of the important input parameters in seismic response analysis of the ground. Various methods have been examined to measure the soil Vs directly. Direct measurement of ...
The Ocean Biogeographic Information System (OBIS) grew from a series of workshops funded by the Sloan Foundation to explore the feasibility and goals of a Census for Marine Life. During the workshop t...
We explored the use of stable nitrogen (N) isotope analysis to assess trophic position of consumers in two marine ecosystems: the kelp forests of southern California and a coral atoll in the tropical ...
The relationships between conformation and longevity traits were analysed in 58 493 Czech Fleckvieh cows first calved from 1994 to 2003. All cows were scored for conformation during the first lactatio...
Test-day records of purebred Tsigai, Improved Valachian and Lacaune ewes were used to analyse the effect of environmental factors on milk fat and protein content. There were 121 424 and 121 158 measur...
This dissertation uses a combination of microbiology, mineralogy, and geochemistry to understand dissimilatory iron reduction in hyperthermophilic archaea and the role and potential impact of these an...
Four Korean native cattle (KNC) breeds—Hanwoo, Chikso, Heugu, and Jeju black—are entered in the Domestic Animal Diversity Information System of the United Nations Food and Agriculture Organization (FA...
