Selection leads to genetic improvement but also reduces genetic variation in the progeny. When all animals in a population are closely related there is little genetic variation and little scope for further genetic progress. Mate selection procedures are used to help maintain genetic variation, and hence genetic progress, in the future and to avoid the fitness problems related to severe inbreeding.

This final rule amends the Clinical Laboratory Improvement Amendments of 1988 (CLIA) regulations to specify that, upon the request of a patient (or the patient's personal representative), laboratories subject to CLIA may provide the patient, the patient's personal representative, or a person designated by the patient, as applicable, with copies of completed test reports that, using the laborato...

Selection strategies for the genetic improvement of reproductive performance of sheep in Australia are discussed in the context of current and emerging industry practice. The predicted rates of gain in reproductive rate are compared with varying amounts of pedigree and performance records of relatives. The paper also considers the merits of exploiting indirect as well as direct selection, inclu...

Aligning Financial Incentives (FIs) to health policy goals is becoming increasingly popular. In many cases, such initiatives have failed to deliver anticipated benefits. Attributing this to the actions of self-interested and resistant professionals is not an entirely helpful approach. It is important to avoid simplistic assumptions to build knowledge of how and why schemes are implemented in pr...

CONTEXT Short-contact application of 0.1% tazarotene gel for acne was devised to minimize local adverse effects. Its efficacy and safety are unknown. OBJECTIVES To assess acne improvement and tolerability during 12 weeks of short-contact treatment with 0.1% tazarotene gel vs a nonmedicated gel control. DESIGN A randomized, masked, vehicle-controlled trial. SETTING Outpatient facilities at...

the aim of this research was to explain the difference in the dimensions of learning organization between federations of team and individual sports. this research was a comparative survey. the statistical population consisted of 795 fulltime employees of iran sport federations. out of 212 returned questionnaires, 158 questioners were from individual sport federations and 54 from team sport fede...

The solar radiation absorbed by the photovoltaic thermal systems and not transformed into electricity creates a problem that significantly influences reliability efficiency of cells. In order to passively solve this in hot arid climate, night radiative cooling technology was proposed work, where water system cooled circulating collector exploiting technique, it used next day for For aim, mathem...

Entrapped air in the chambers of a T-girder bridge generates considerably large vertical force which is harmful to safety superstructure. The contribution entrapped not considered when calculating flood related specifications, and also it has been taken into account by researchers. Two-dimensional, scaled-down models at 1:40 scale are selected as research object. Analytical numerical methods em...
