We examine the validity of classical approximation waterfall phase transition in hybrid inflation from an effective field theory (EFT) point view. The EFT is constructed by integrating out fluctuations, up to one-loop order perturbative expansion. Assuming slow-roll conditions are obeyed, right after onset phase, we find backreaction fluctuations evolution system can be dominant. In this case c...

The integrability of the Bukhvostov–Lipatov four-fermion model is investigated. It is shown that the classical model possesses a current of Lorentz spin 3, conserved both in the bulk and on the half-line for specific types of boundary actions. It is then established that the conservation law is spoiled at the quantum level — a fact that might indicate that the quantum Bukhvostov–Lipatovmodel is...

ing to use the old maize after careful selection and rejection of spoiled grains (some 40 maunds were thus lost out of 100). I decided to use the carefully picked old maize. The rice was new, that is, it was purchased in end of December, and was at least three months old ; but, where possible, I prefer rice a couple of months older to begin with. It so happened therefore that on the 21st March ...

Three different strains of bacteria isolated from spoiled, uncooked chicken were grown in pure culture on Trypticase soy agar supplemented with yeast extract. The volatile organic compounds produced by each culture were concentrated on a porous polymer precolumn and analyzed by high-resolution gas chromatographic mass spectrometry. Twenty different compounds were identified. Both qualitative an...

Despite the fact that precarious modes of employment have become increasingly common in academic careers, studies shown contracts are often hidden and masked within higher education structures. This has important implications for identities those on such contracts. paper uses Goffman’s work stigma, ‘spoiled identities’, identity management, Archer’s concepts morphostasis morphogenesis as heuris...

Maintenance of HVAC&R systems and scheduled replacement of components to avoid costly down time, degraded comfort conditions, or health hazards is not new. In fact, designs have not changed dramatically in many years. However, new regulations placed on CFC emissions and other environmental and energy conservation concerns are causing changes. On the traditional side of things, cost for down tim...
