Research ArticleOpen accessIn the abstractWound Healing Process of Uncomplicated “Rusterholz” Ulcer, Following Treatment by Wooden Block and Hoofgel® in Bovine Hoof: Histopathological AspectsH. Azarabad, I. Nowrouzian, E. Soleymani et al.A broad and very detailed histopathological knowledge on cutaneous wound healing particularly in human skin is available, but few studies have documented this event in bovine claw sole ulcers. It seems the mechanism of wound healing might be basically the same followed by second intention healing which is finished in a period of time by formation of granulation tissue in … …American Journal of Animal and Veterinary Sciences, Vol. 1, Issue 2 · 31 Dec 2006 · 7,853 accessesView PDFCite
Research ArticleOpen accessIn the abstractResonance in Satellite's Motion Under Air DragRashmi Bhardwaj, Mani SethiThis article studies the attitude motion of a satellite in a circular orbit under the influence of central body of mass M and its moon of mass m, whose orbit is assumed to be circular and coplanar with the orbit of the satellite. The body is assumed to be tri-axial body with principal moments of inertia A < B < … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 7,003 accessesView PDFCite
Research ArticleOpen accessIn the abstractRecovery and Germination of Grass Seeds Ingested by CattleFerhat GökbulakSeeds of bluebunch wheatgrass [Psuedoroegneria spicata (Pursh) A. Love] and Sandberg bluegrass (Poa secunda Presl.) were fed to Holstein heifers in different amounts to investigate the effects of seed feeding level and seed size on the recovery and germinability of passed seed. Animals were fed 60,000, 30,000,15,000, and 7,500 seeds of each species. Passed seeds were recovered from dungcollected daily … …OnLine Journal of Biological Sciences, Vol. 6, Issue 1 · 30 Jun 2006 · 6,756 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntagonism Between Chlorpyrifos and Flaxedil in Toad and Earthworm Neuromuscular TransmissionYong-Chiang Chang, Amauri B. Bartoszeck, Samir A. Madeira, Charles I. AbramsonThe cholinesterase inhibition effect of chlorpyrifos, a commercial insecticide, was tested by its antagonism to the acetylcholine inhibition effect of flaxedil in 30 isolated nerve-sartorius muscle preparations of the toad, compared with its antagonism in 30 isolated nerve cord-body wall muscle preparations of the earthworm. Inhibition and facilitation in this antagonism were measured by changes in depolarizing rate of toad … …American Journal of Environmental Sciences, Vol. 2, Issue 2 · 30 Jun 2006 · 6,396 accessesView PDFCite

About 95-99% of Fly Ash consists of oxides of Si, Al, Fe and Ca, about 0.5 to 3.5% consists of Na, P, K and S and the remainder is composed of trace … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,017 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Crosslinker and Monomer to the Polymerization of Polymethacrylamide Gel Dosimeters by Direct and Indirect MethodsElias Saion, A. H. Shaari, M. Z.A. Rahman et al.Radiation-induced polymerization in Polymethacrylamide Gels (PMAAGs) potentially used for 3D dose verification in radiotherapy has been studied using both Raman spectroscopy and Nuclear Magnetic Resonance (NMR) method. The dosimeters are composed of aqueous Methacrylamide (MAA) monomer and N, N’ methyelene-bis-acrylamide (BIS) crosslinker at various concentrations from 2 to 6% (w/w) and gelatin at 6% (w/w). The dosimeters were irradiated to … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 7,170 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiological Activity of Methyl tert-butyl Ether in Relation to Soil Microorganisms has a Negative Environmental ImpactGholam H.S. BonjarFuel oxygenates are added to gasoline to enhance combustion efficiency of automobiles and reduce air pollution. Methyl tert-butyl ether (MTBE) is the most commonly used oxygenate because of its low cost, high-octane level and ease of blending with gasoline. However, due to its water solubility, high mobility and low biodegradability it leaches in soil subsurface at the speed of groundwater. … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,665 accessesView PDFCite
