Six male college long jumpers volunteered as subjects
to determine the kinematic differences between depth jumps
from 0.75 m and 1.10 m, and long jump take-off. The variables
examined were approach and take-off vertical, horizontal
and resultant velocities with contact time and
angles of take-off.
Subjects undertook six depth jump...
Past research has implied that differences in blender performance
between commercial and laboratory particleboard blenders
may not be attributed to resin distribution between screen fractions,
as is commonly believed in the industry today, but to which particles
within a screen fraction have resin and which do note
To test this,...
In 2006, NASA led a field campaign to investigate the factors that control the fate of African easterly waves (AEWs) moving westward into the tropical Atlantic Ocean. Aircraft and surface-based equipment were based on Cape Verde's islands, helping to fill some of the data void between Africa and the Caribbean....
Reconciling conservation and livelihoods is a concern wherever forests are important in local people’s lives. We plead for engaging these people in survey activities to clarify what is important to them, as a first step in conservation planning. This will help to address their priorities and gain their guidance and...
This paper demonstrates the use of model-based predictive control for energy
storage systems to improve the dispatchability of wind power plants. Large-scale wind
penetration increases the variability of power flow on the grid, thus increasing reserve
requirements. Large energy storage systems collocated with wind farms can improve
dispatchability of the...
Medusahead [Taeniatherum caput-medusae (L.) Nevski], a non-native, winter-annual grass (Poaceae), has
invaded rangelands throughout the western USA. Medusahead is an aggressive competitor that crowds out native plants
and reduces forage for wildlife and livestock. Sulfometuron methyl is a sulfonylurea herbicide used to control medusahead,
but its effect on non-target native...
A fast-response chromel–constantan thermocouple sensor was constructed for use on the microstructure profiler Chameleon and used for 60 ocean profiles off the coast of Oregon. The stability of the thermocouple was compared to that of an FP07 microbead thermistor, and its frequency response was compared to a high-resolution microconductivity probe....
Our component of the TROPIC HEAT 1987 experiment was
designed to investigate a number of questions raised by our
TROPIC HEAT 1984 measurements (Park et al, 1985; Mourn and
Caldwell, 1985; Mourn et al, 1986; Chereskin et al, 1986; Mourn et
al; 1987). In particular, the goals of LEG 2...
MILDEX, a mixed layer dynamics experiment, began
October 21, 1983 and lasted until November 16, 1983.
R.P. Flip, R.V. Wecoma and R.V. Acania rendezvoused at
34° N, 127° W to participate in joint observations of
the mixed layer and upper ocean. This report contains
data from the WAve Zone Profiler,...
