Meiotic cell-cycle progression in progesterone-stimulated Xenopus oocytes requires that the translation of pre-existing maternal mRNAs occur in a strict temporal order. Timing of translation is regulated through elements within the mRNA 3' untranslated region (3' UTR), which respond to cell cycle-dependant signalling. One element that has been previously implicated in the temporal control of mR...
A total of ninety seven pre-pubertal Bunaji (BJ) and Friesian-Bunaji (FR x BJ) heifers were allotted randomly to two treatments groups for a period of 15 months. The treatment groups consisted of the followings: Mature Bull Exposure (MBE) and No Bull Exposure (NBE). Heifers were body condition scored and their live weights recorded on 28 days consecutive intervals. A heifer tactile stimulation ...
A fast Monte Carlo simulator with a graphical user interface is an ideal education tool for students learning about molecular beam epitaxy (MBE). This paper discusses the implementation of such a simulator, as well as simulation techniques that may be used to tailor surfaces. Simulations carried out on the learning tool show how MBE can recover step-flow growth, in addition to the temperature d...
A new analytic theory is developed for asymptotic stage of self-catalyzed growth III-V nanowires (NWs) by molecular beam epitaxy (MBE), where NWs collect all group III atoms deposited from vapor. The shadowing NW length derived which corresponds the full substrate surface in MBE. and radius are depending on effective deposition thickness MBE parameters. It shown that increases, their decreases ...
