A simulation model capable of execution on a programmable
calculator was developed to study voluntary intake,
liveweight change, and fertility of grade Zebu cows in the
Llanos of Colombia. Organic nitrogen in the diet and meta
bolic weight were used to predict intake; age, liveweight,
and energy concentration were the...
A 2x2 factorial experimental design with 2 replications was
used to study the effects of a combination of electrical stimulation
and delayed chilling of pre-rigor muscle on meat characteristics.
Twenty Standard and Good grade beef cattle were slaughtered and 5
carcasses were assigned to each of the 4 treatments. Meat...
I. Frozen bovine semen samples were measured by flow cytometry
(FCM) to determine if FCM analyses could be useful for sperm quality
evaluation and prediction of bull fertility. Fluorescent dyes
utilized were acridine orange, to measure sperm nuclear chromatin
heterogeneity by quantifying susceptibility of the chromatin to
denaturation, and rhodamine...
Most of the feed required for poultry production in
the Republic of Yemen is imported from Europe. Sometimes,
feed shipments arrive later due to lack of hard currencies
to pay for the feed or to pay the freight charges. Yemeni
broiler producers in such cases feed their birds a single...
This experiment is concerned with sampling submicrometer
particles in near sonic and supersonic flows.
The study employed a high volume condensation aerosol
generator to produce stearic acid particles having a
geometric mean diameter of 0.8 μm and a geometric
standard deviation of 1.28. The aerosol was diluted
with dry air...
Six experiments were carried out with Single Comb White Leghorn laying chickens to
assess the effect of feeding a source of direct-fed microbials (Lactobacillus; Lacto) and its
carrier [condensed cane molasses solubles (CCMS)] on the retentions of fat, nitrogen and
several minerals; on the status of the pH of the...
The adsorption equilibrium and kinetic behavior exhibited
by β-lactoglobulin at silanized silicon surfaces of varying
hydrophobicity were examined using ellipsometry. Adsorption
equilibrium results were used to construct adsorption
isotherms; the adsorbed mass of β-lactoglobulin was observed
to increase with increasing surface hydrophobicity, within a
defined range of hydrophobicity. Adsorption kinetics...
The assumption of constant quartz accumulation for the deep-sea
sediment core Y69-106P, taken in the Panama Basin, has been
used to date the core and construct a sedimentation rate versus time
curve for it. Stratigraphic control for the calculated time scale
includes three carbon-14 measurements, the extinction of the
radiolarian...
Thermo-hygro-rheology of wood-adhesive systems plays an important role during the hot pressing process of wood based composites. The principal objective of this research is to quantitatively study the thermo-hygro rheological characteristics of wood-adhesive systems used in such composites. This is with a view to providing material characteristics which may be...
