More than 2.3 billion pounds of pesticides with a value of $4.1 billions are applied by farmworkers to agricultural crops each year. These chemicals applied to farm lands lead not only to acute and chronic health effects, they also enter the groundwater and food chain of populations. In recent years...
Boron sprays produced fruit set increases in 'Barcelona'
hazelnut orchards in 1984 and in 1985. The absolute fruit set was
correlated with leaf B content but not with nut B. With relative
fruit set (RFS), B content of nuts in May (r = 0.63**) was more
strongly related to set...
Nucleation and growth kinetics of oxygen precipitates and bulk
defects in epitaxial silicon wafers were investigated. Low temperature
nucleation heat treatments were applied to the well characterized
epitaxial silicon wafers before and after the epitaxial deposition
processing. Subsequently the wafers were heat treated at a high
temperature.
In the case...
Rates of germination and emergence of corn were measured as
influenced by soil physical parameters using blotter paper and a sandy
loam soil as growth media. The corn seeds used were a hybrid of
Funk's (DJ7xLH93).
Experimental conditions were soil temperature of 20°C, 25°C,
30°C, and 35°C, soil water potential...
In rodent models as well as in fish models there are significant
species differences in the susceptibility toward aflatoxin B₁ (AFB₁)
carcinogenesis. Mouse is less susceptible toward AFB₁ carcinogenesis
than rat. Researchers have come to the conclusion that the lower
susceptibility of mice is not a result of less effective...
Documentation of the side effects of pesticides on
arthropod natural enemies has expanded rapidly since the
1950's as part of an increase in non-target side effects
literature. Most reviews have been based on empirical
analysis of selected literature. The SELCTV database was
developed to make a larger information base accessible...
The Salt Range and Potwar Plateau are part of the currently active
foreland fold-thrust belt of the Himalaya in Pakistan. Seismic reflection data have been combined with surface mapping, drillhole and
paleomagnetic information to construct balanced structural cross-sections of the current frontal thrust zone (Salt Range), and to estimate
the...
