Pathogenesis Hoerlein determined that intervertebral disc disease (IVDD) accounted for 2.02% of all diseases diagnosed in dogs (Hoerlein 1952). Incidence of IVDD peaks at 4 to 6 years of age in chondrodystrophic breeds and at 6 to 8 years in nonchondrodystrophic breeds (Priester 1976). The Dachshund had the highest frequency followed in succession by the Pekingese, Welsh corgi, Beagle, Lhasa Ap...

this study describes the result of relationship between disc personality types and pay to performance system. also, describe the relationship between herzberg two-factor model and pay to performance. we invited 300 mangers’ of bank refahe kargaran to participate in the study through random selection and received 208 returned responses. the responses rate was 69.3 percent. the data used in this ...

This analysis of the introduction of racial theories to Brazil and their reception by Brazilian intellectuals in the late nineteenth/early twentieth centuries looks at miscegenation, racism, and whitening policies through the lenses of two novels that bear witness to the era's mentality: O cortiço (1890; A Brazilian tenement, 1976), by Aluísio Azevedo, and Canaã (1902; Canaan, 1920), by Graça A...

Rock anisotropy plays an important role in engineering behavior of rocks. Slates are anisotropic rocks which have long been used for gable roof, floor tiles, borrow materials, and other purposes. The slates studied in this research are calcareous and have a porphyro-lepidoblastic texture. To determine the role of the anisotropy on the tensile strength and fracture pattern, two variables includi...

An interaction between a star-disc system and another star will perturb the disc, possibly resulting in a significant modification of the disc structure and its properties. It is still unclear if such an encounter can trigger fragmentation of the disc to form brown dwarfs or gas giant planets. This paper details high resolution Smoothed Particle Hydrodynamics (SPH) simulations investigating the...

We present time-dependent simulations of a two-phase accretion flow around a black hole. The accretion flow initially is composed of an optically thick and cool disc close to the midplane, while on top and below the disc there is a hot and optically thin corona. We consider several interaction mechanisms as heating of the disc by the corona and Compton cooling of the corona by the soft photons ...

brazilian peppertree (schinus terebinthifolius) leaf extract was applied against two strains of the crown gall disease agent (agrobacterium tumefaciens); strains c58 and ar125. in vitro, we used the agar well diffusion method and the extract was tested in different solvents selected according to their polarity indices, at different concentrations and different incubation temperatures. in vivo, ...

The unsustainable use of resources and the rising demand for traditional concrete have disrupted ecological equilibrium, necessitating adoption a more appropriate long-lasting alternative. One such substitute cement in production is geopolymer concrete, although this material prone to cracking fracturing due its low tensile strength, leading costly repairs or even structural collapse. Fiber-rei...
