In a previous communication it was reported that under certain dietary conditions, depending on the source of the vitamin B complex, homocystine was incapable of replacing methionine for the support of growth of animals on a cystine-methionine-free diet (l), a finding which was corroborated by Rose and Rice (2). On the other hand we were able to confirm their observation that with tikitiki and ...

Parameter uncertainty and sensitivity for a watershed-scale simulation model in Portugal were explored to identify the most critical model parameters in terms of model calibration and prediction. The research is intended tohelpprovideguidance regardingallocationof limiteddata collection andmodel parameterization resources for modelers working in any data and resource limited environment. The wa...

This study evaluates the watershed-scale effects of non-point-source (NPS) pollution loads caused by rice straw mulching and no-tillage applications in upland crop areas using the Hydrological Simulation Program–Fortran (HSPF) model. The study area is the Byulmi-cheon watershed (1.21 km2) of South Korea. Hourly rainfall, discharge and stream water quality data were collected for three years (20...

astrocytes, as well as Hort.ega's triple impregna tions, did not reveal protoplasmic processes of the tumor cells, it was unlikely that the tumor was of neuro-ectodermal origin. The possibility of a mesodermal tumor, although suggested by a pen vascular arrangement of the tumor cells, found little support from the results of special technics. Azan stains revealed no collagen outside the vu cula...

Hydrologic models are essential to watershed planning and management, particularly in the San Antonio River watershed where competition for scarce water resources is a challenge. As a result, the calibration and validation of hydrologic models are essential steps for their successful application. In this study, we examined the use of a loosely coupled genetic algorithm (GA) as an autocalibratio...

These control-release formulations also decrease pestiThe modification of smectitic clays with organic cations via cationcides losses by offering protection from other processes exchange reactions produces sorbents with an increased sorption capacity for organic compounds such as acidic herbicides. These organoclays such as volatilization (El-Nah...
