Gastrointestinal helminths of dogs in Western Pomerania, Poland.
A total of 763 fecal samples were collected from dogs in Western Pomerania during 2006-2007 to determine the gastrointestinal parasite fauna of dogs in this region. In the city of Szczecin, 648 fecal samples were collected every month in the annual cycle from nine city areas and analysed. Six fecal samples were taken at each collection time from each site. A total of 115 fecal samples from rura...
متن کاملGamma Spectrometric Analysis of Iron Ore Samples of Arak, Iran
Introduction Iron ore is one of the most important natural raw materials that is widely used for manufacturing iron and steel. This type of ore contains various amounts of radionuclides; thus, exposing workers handling their extraction, transportation, and processing to radiation. Materials and Methods In this study, 12 ore samples (each mass weighing about 2 kg) were collected from the iron or...
متن کاملSweet Spot Supersymmetry
We find that there is no supersymmetric flavor/CP problem, μ-problem, cosmological moduli/gravitino problem or dimension four/five proton decay problem in a class of supersymmetric theories with O(1) GeV gravitino mass. The cosmic abundance of the nonthermally produced gravitinos naturally explains the dark matter component of the universe. A mild hierarchy between the mass scale of supersymmet...
متن کاملPerceiving the sweet spot.
Many sports involve aligning a hitting implement with a ball trajectory such that contact is made at the implement's center of percussion or 'sweet spot'. This spot is not visibly distinct; its perception must be haptic. Although it is functionally defined with respect to contact--it is the point of impact that produces the least vibration in the hand holding the implement--hitting success requ...
