An increase in anthropogenic activities since the industrial revolution, primarily due to burning of fossil fuels and changes in land cover, has resulted in a steady increase in the global mean atmospheric CO2 concentrations. While there is unequivocal scientific evidence on global warming and its multidimensional impacts on natural and...
The aim of this study was to investigate the vitamin B-6 status of Saudi adult males and compare the status between rural and urban subjects. Fifty-one adult male subjects were recruited from urban (n=31) and rural (n=20) populations of Riyadh. These subjects were reclassified to cigarette smokers (n=19), water pipe...
Gamma Ray Bursts (GRBs) are the most energetic explosions in the Universe, producing up to $\sim10^{53}$ ergs of energy in the first few seconds of their emission -- the so-called prompt phase that is dominated by high energy X-ray and $\gamma$-ray photons. The very large luminosities released in these events...
The development of the energy crisis has caused the
use of depletable energy resources to be monitored quite
closely in the United States. Within the agricultural
sector, irrigation is a large user of energy, with the
potential of using many times more energy than all other
agricultural field operations. A...
Oxide materials exhibit a wide variety of structures and properties. In particular, transition metal oxides tend to be highly stable while exhibiting a wide range of properties that can be used for numerous applications. This work focuses on investigating how the structures’ of 4d and 5d transition metal oxides influences...
Variation in cheese quality due to geographic location is important to cheese producers, consumers, and retailers on a global level. Understanding the impacts of geographic location of cheese plants may be useful to businesses for marketing, cost reduction, and quality improvement. Many aspects of variation due to geography have been...
The persistent color (pc) trait in snap bean (Phaseolus vulgaris L.) belongs to a member of the cosmetic stay-green gene family. It is considered very desirable by snap bean breeders for its impacts on pod quality. Persistent color imparts a uniform dark-green color to pods and expresses in seeds as...
The goal of this dissertation was to improve our abilities in acquiring critical in vivo data by establishing embryo-larva zebrafish as an exemplary model to quantitatively evaluate cancer progression. The living environment that encompasses a tumor has a significant effect on how cancer develops, grows and metastasizes. In order to...
The Great Recession, which resulted from the burst of housing bubble and officially lasted from December 2007 to June 2009, started as a national recession in the U.S. and then affected countries across the world. Economies reacted differently to this recession and those systems that lost fewer jobs and/or recovered...
The last century has experienced a marked increase in emerging infectious disease (EID, hereafter) – jeopardizing human, domestic animal, and wildlife health. EIDs are commonly associated with spillover from one host species into a novel host species, with many destructive diseases, for both livestock and wildlife, emerging at the wildlife-livestock...
