The objectives of POL’s research for 2002 has been to; (i) Provide continued guidance design criteria to OMNI Technologies for the development of acoustic suspended sediment and flow measuring instrumentation, which is to be mounted on the surface of a mine. (ii) The calibration of one of the systems developed by OMNI in the sediment tower at POL. (iii) The assessment of scattering models for s...

This study investigated the effects of pelvic suspension on the meat quality of M. longissimus dorsi, M. semimembranosus and M. adductor from 35 heifers with at least 75% Charolais breeding. Two-thirds of the heifers were slaughtered directly from pasture at 18 months of age and one-third was finished indoors and slaughtered at 22 months. After slaughter and electrical stimulation one side of e...

The influence of soy-protein diet on brain lipid peroxidation in female rats was studied using a tail-suspension model of weightlessness. The study tested the efficacy of diets containing 0% or 11.1% soy-protein in 4 groups of female Sprague Dawley rats that were maintained with or without tail-suspension for a period of 3 weeks. At term, the whole brain was removed, segmented, and analyzed for...

When suspended in methylcellulose, primary mouse keratinocytes cease proliferation and differentiate. Suspension also reduces the activity of the cyclindependent kinase cdk2, an important cell cycle regulatory enzyme. To determine how suspension modulates these events, we examined its effects on wild-type keratinocytes and keratinocytes nullizygous for the cdk2 inhibitor p21. After suspension o...

When colloidal particles are suspended in a liquid, the particle suspension can be stable or unstable. Particles in a stable suspension are dispersed individually. In an unstable suspension, particles aggregate. This means that particles stick to each other, first they form doublets, and later larger aggregates. When there are only small aggregates, one refers to early stages of the aggregation...

The need for accurate in vitro dosimetry remains a major obstacle to the development of cost-effective toxicological screening methods for engineered nanomaterials. An important key to accurate in vitro dosimetry is the characterization of sedimentation and diffusion rates of nanoparticles suspended in culture media, which largely depend upon the effective density and diameter of formed agglome...

• Suspended sediments distribution and its variance indicates their preferential gatherings non-uniformity. Vertical vorticity component coincides well with particle out of a mixing layer. Large-scale turbulent structures along the side vegetation patch deplete particles away from The parcels are located periphery large eddies. Increase Dn ( < 0.1) accelerates vertical suspension particles. Tur...

Research suggests that suspension is not an effective deterrent and that more should be done to meet the needs of those who are continually suspended.

1 Hindlimb suspension induces extensive muscle atrophy in plantar flexor muscles that contain 2 predominantly slow-twitch fibers (e.g., soleus). However, plantar flexor muscles containing a high 3 percentage of fast twitch fibers (e.g., gastrocnemius) also atrophy. Although apoptosis has been 4 demonstrated in soleus during hindlimb suspension, it is not known whether apoptosis is also involved...
