An anaemic baby is more susceptible to infection than the normal infant3' and this, is an important factor in the mortality rate of infants of subnormal birth weight. Lichtenstein6, from his extensive work with premature babies, concluded that these infants regularly become anaemic in the first months of life although they are not anaemic at birth. The average haemoglobin level of thirty-six pr...

The topic of this paper is experimental and numerical analysis the impact strength unreinforced concrete slabs. Impact significant in case some accidental loads during exploitation. can be determined experimentally, using Drop-weight test, Charpy Projectile Explosive etc. In research, a model for determining slabs based on Finite element method (FEM) high-end engineering software has been propo...

Polytetrafluoroethylene/aluminum/tungsten (PTFE/Al/W) reactive materials of three different component mass ratios (73.5/26.5/0, 68.8/24.2/7 and 63.6/22.4/14) were studied in this research. Different from the PTFE/Al/W composites published elsewhere, the materials in our research were fabricated under a much lower sintering temperature and for a much shorter duration to achieve a brittle propert...

electrospinning is a method of nanofiber filter media production. by this method, it is possibleto produce media with nanofiber in the range of nanometer to micrometer. nanofibrous media provide a large specific surface area in a finite volume thus they are suitable for filtration applications. in this study, nanofiber non-woven membranes production of nylon-6 by electrospinning method is inves...

The main objective of this work was to determine the optimum level pruning in pitaya. In addition, we want establish relationship between levels and intensity flowering, flowering heavy flower bud drop that affects species. With these aims, two experiments were performed on Hylocereus undatus [(Haw.) Britton Rose] cultivated greenhouses trained a trellis system. Our results conclude cane leavin...

A series of drop weight tests were conducted to evaluate the dynamic flatwise compression strength and flexural strength of sandwich panels with a novel core structure. This sandwich core material, known as Norcore, consists of interconnected cells in a unique configuration of truncated pyramid with sloping cell walls. Core materials made of thermoplastic including virgin Lexan, polycarbonate, ...

The dynamics of drop formation and pinch-off have been investigated for a series of low viscosity elastic fluids possessing similar shear viscosities, but differing substantially in elastic properties. On initial approach to the pinch region, the viscoelastic fluids all exhibit the same global necking behaviour that is observed for a Newtonian fluid of equivalent shear viscosity. For these low ...

PURPOSE To study histopathological findings due to a model of closed head injury by weight loss in rats. METHODS A platform was used to induce closed cranial lesion controlled by weight loss with a known and predefined energy. 25 male Wistar rats (Rattus novergicus albinus) were divided in five equal groups which received different cranial impact energy levels: G1, G2, G3 and G4 with 0.234J, ...
