When water is plentiful, growers usually schedule irrigation practices around other farming activities. For example, most growers change furrow irrigation sets at 12- or 24-hour intervals because this timing is convenient and uses labor efficiently. When water is in short supply, you need to rethink some practices to obtain maximum...
Phosphorus is an essential building block for all forms of life, from plants to animals, including humans. Because phosphorus is closely tied to land productivity and plant growth, many homeowners apply phosphorus fertilizers liberally to lawns, while growers add them to cropland. However, in certain environments, too much phosphorus can...
El fósforo es un componente esencial para toda forma de vida, tanto para las plantas como para los animales, incluso los seres humanos. El fósforo es importante para la productividad del suelo y el crecimiento de plantas. Por eso, los dueños de casa a menudo fertilizan el césped con grandes...
Shocked porous granular material experiences pressure dependent compaction. D. John
Pastine introduced a model in which the degree of compaction is dependent on the pressure induced
by the shock wave, the shear strength of the material, and the distribution of void sizes. In the
past, the model could only be...
This thesis seeks to explore how visual cues in the new environment affect Chinese international students studying abroad in the United States. Through open-ended interviews, Photovoice, and focus groups, Chinese international students shared their perspectives on their orientation, residence, campus places, color association, and on-campus place preferences. During the study,...
Anaerobic digestion is a microbially mediated process by which organic matter is decomposed in the absence of oxygen. The end products of anaerobic digestion include treated sludge and biogas, a mixture of methane and carbon dioxide, which can be recovered and used for energy generation. The majority of wastewater treatment...
This study examined the potentially stressful
effects of tagging juvenile rainbow trout Oncorhynchus mykiss
with passive integrated transponder (PIT) tags by measuring
short-term (<120-h) changes in plasma concentrations of
cortisol and hepatic heat shock protein 70 (hsp70). In a
laboratory experiment, plasma cortisol levels were measured
in fish before they...
