Supersymmetric models are typically taken to have p parameter and all soft supersymmetry breaking parameters at or near the weak scale. We point out that a small window of allowed values exists in which ~1 and the electroweak gaugino masses are in the few GeV range. Such models naturally solve the supersymmetry CP problem, can reduce the discrepancy in &,, and suppress proton decay. In this win...

We study the asymptotic behaviour of solutions to the porous media equation in an exterior domain, Ω, which excludes one or several holes, with zero Dirichlet data on ∂Ω. We prove that, when the space dimension is three or more, this behaviour is given by a Barenblatt function away from the fixed boundary ∂Ω and near the free-boundary. On the other hand, if we scale the solution according to it...

Sixty-four white-faced rams and wethers were dressed with the aid of a commercial pelt puller. The effects of age, castration, and season on difficulty of pelt removal and pelt damage were evaluated. Lambs were divided into two age groups (5 and 12 mo) within gender (ram and whether) and season (spring and fall). A greater force (P less than .05) was required to remove pelts from rams than from...

Sequence data from cDNA and genomic clones, coupled with analyses of expressed sequence tag databases, indicate that the CesA (cellulose synthase) gene family from barley (Hordeum vulgare) has at least eight members, which are distributed across the genome. Quantitative polymerase chain reaction has been used to determine the relative abundance of mRNA transcripts for individual HvCesA genes in...

Beneficial effects of leaving residue at the soil surface are well documented for steep lands, but not for flat lands that are drained with surface inlets and tile lines. This study quantified the effects of tillage and nutrient source on tile line and surface inlet water quality under continuous corn (Zea mays L.) from relatively flat lands (<3%). Tillage treatments were either fall chisel or ...

background: prevalence of fall-related mortality is rising in the elderly population. falling is one of the causes of the murderous and non-murderous injuries in the elderly population which can lead to disability, dependence and decline of quality of life. fractures constitute a major part of the fall-related injuries. the present study is designed to investigate the prevalence of fall-related...

objectives: this study aimed to identify elderly fallers and non-fallers by balance test under dual tasks conditions. methods & materials: this study was an analyze-comparative study. subjects were from three park of tehran. subjects were 20 older adults with outhistory of falls (aged 75.95±6.28 years) and 21 older adults with a history of 2 or more falls in the previous one year (aged 72.50±7....

The structure of a discharge across a magnetic field in a dusty plasma is analysed. The dust macroparticles are negatively charged, but are unmagnetized because of their high mass. The electrons are highly magnetized, and the ions have intermediate magnetization. This results in different transport rates of the different species across the magnetic field. Depending on the size of the magnetic f...

Access to livestock manure is increasing in semi-arid cropping systems of U.S. Northwest prompting evaluation fertilization strategies on regional production systems. A study conducted from fall 2012 2019 used: fall- or spring-applied dairy (56 Mg ha−1), fall-applied composted (33 urea SUPERU (Koch Agronomic Services), and a control (n = 6) corn (Zea mays L.)–barley (Hordeum vulgare L.)–alfalfa...

The mechanisms of stress-assisted grain growth are explored using molecular dynamics simulations of nanoindentation in nanocrystalline Ni and Ni-1 at.% P as a function of grain size and deformation temperature. Grain coalescence is primarily confined to the high stress region beneath the simulated indentation zone in nanocrystalline Ni with a grain size of 3 nm. Grain orientation and atomic dis...
