Vegetable oils have always played an essential role in the diet of man, besides being an important raw material in many industries. The demand for these oils increases with the population and through the discovery of new uses for them. In order to meet this increasing demand, oils from new,...
Achondroplastic dwarf men and women find it difficult to acquire
clothing that fits well. Their major problem is that their torso is
long in relationship to the length of their arms and legs, but other
physical problems do enter into the selection and construction of
clothing. The multiplicity of their...
Male Sprague Dawley rats received a single intraperitoneal dose
of BCNU in experiments designed to measure biochemical changes associated with the pulmonary toxicity described for this agent. Changes in
serum and lung lavage angiotensin converting enzyme (ACE) activity
were measured to detect changes in pulmonary endothelial cell integrity. Alpha-1-proteinase inhibitor...
Previous investigation showed that 20 mg/kg BCNU
caused inhibition of sulfobromophthalein (BSP) excretion
and inhibited bile salt independent bile flow (BSIF) in
rats by 48 h after treatment (Hoyt, 1984).
The present investigation demonstrated that BCNU
inhibited the canalicular step in the excretion of BSP.
This was indicated by the...
A general procedure is presented for calibrating a model
for rainfall erosivity based on daily rainfall. The approach
is based on probability distributions of wet-day
precipitation amount and monthly erosivities which are
inferred from published data summaries. The calibrated
model was tested by comparisons with erosivities
computed from hourly precipitation...
Distributed temperature data are used as input and
as calibration data for an energy based temperature model
of a first order stream in Luxembourg. A DTS (Distributed
Temperature Sensing) system with a fiber optic cable of
1500m was used to measure stream water temperature with
1m resolution each 2 min....
Several methods of infering plant water stress for
irrigation scheduling are based upon measurements of the
environment in which the plants grow. These measurements
include parameters such as soil water content, air
temperature, pan evaporation and incident radiation. It is
hypothesized that improved estimates of plant water deficit
can be...
Groundwater resources have become seriously threatened
due to improper use by industrial, municipal, and even public
sectors. Widespread contamination of aquifer systems has
jeopardized human health and the environment and methods for
restoring these systems are needed. Biological and chemical
in situ remediation, where contaminants are degraded within
the natural...
Precise management of the changing matric potential during infiltration into unsaturated soil required the development of miniature, high-speed, planar tensiometers. A novel design was developed, with response time of less than 1 s. The applicability of the devices is shown through measurements of the matric potential in growing instabilities, both...
