Crop coefficient curves provide simple, reproducible means to estimate crop evapotranspiration (ET) from weather-based reference ET values. The dual crop coefficient sKcd method of the Food and Agricultural Organization of the United States (FAO) Irrigation and Drainage Paper No. 56 (FAO-56) is intended to improve daily simulation of crop ET by considering(More)
Although many animals deposit scent marks, previous studies have focused almost entirely on rodents or on the chemical structure of the signal. Here, we study the quantity and temporal pattern of chemical deposition by the territorial sagebrush lizard Sceloporus graciosus, measuring both femoral pore and fecal deposits. Specifically, we tested whether(More)
The agricultural use of water is higher than 85% in the western USA, resulting in an increasing water deficit in the region; this situation is commonly encountered throughout the world where irrigated and irrigation-assisted production systems are operational. The objective of this study was to examine differences among dry bean (Phaseolus vulgaris L.)(More)
The effects of intravenous (IV) infusion of human recombinant tumor necrosis factor-α (rTNF-α, Cetus) on normal brain and malignant glioma in rats were examined. Twelve Fischer 344 rats were given either a single injection of 106U rTNF-α or injections of 5 × 105U rTNF-α for three days. One day post-rTNF-α injection (s), rats were injected IV with(More)
Quantifying evapotranspiration (ET) from agricultural fields is important for field water management, water resources planning, and water regulation. Traditionally, ET from agricultural fields has been estimated by multiplying the weather-based reference ET by crop coefficients sKcd determined according to the crop type and the crop growth stage. Recent(More)
The diffusion of water-soluble solutes in water-soaked porous media was studied by following the release of benzoic acid from poly(vinyl stearate) matrices. The results were analyzed using a pseudo-steady-state diffusion model coupled with the fundamental concepts of percolation theory. The results of the study indicated that the relationship between the(More)
Human recombinant tumor necrosis factor-α (rTNF-α) was administered to normal Fischer 344 rats by stereotaxic intracerebral (IC) injection. Animals received a single injection of either 6×104 UrTNF-α or excipient in their right parietal lobe. Others received three consecutive daily injections of either 6×104 U rTNF-α or excipient to examine effects of(More)
A procedure for estimating the molar water solubility (S) for a series of structurally related drug compounds is presented. HPLC methods for the determination of partition coefficients (P) are combined with semiempirical calculations for S. Multidimensional plots are developed with the physical constants S and P along the x and y axes and with a biological(More)
Human recombinant tumor necrosis factor-α (rTNF-α) was administered to normal Fischer 344 rats by stereotaxic intracerebral (IC) injection. Animals receiving a single injection of either 6 x 104 U rTNF-α or an equivalent volume of excipient (vehicle) in their right parietal lobe. In order to demonstrate any effects rTNF-α might have on the blood-brain(More)
