This paper presents an experimental investigation of the effect impact force on residual strength capacity simply supported reactive powder slabs. Eight specimens reinforced concrete slabs with dimensions 500 x mm and 70 in four categories were used. The influences slab compressive (conventional concrete), steel fiber proportion (1, 1.5, 2%), percentage reinforcement tension zone (ρ1=0.007, ρ2=...

A cryogenic pilot distillation column operating at total reflux is described. It was used to measure the pressure drop and flooding of various structured packings, first using pure nitrogen and then using an oxygen-argon mixture. By varying the pressure, the nitrogen system was used to characterize the capacity of each packing via Wallis plots. The oxygen-argon flooding data can be accurately p...

The design and fabrication of a piezoelectric micro actuator on a silicon diaphragm is presented for application of micro ink jet. We developed the micro devices for the fluid transference that are fabricated using thick film technologies for ceramic materials and Si micro-machining. The performance of drop ejection was shown from the optimal design parameters. It is closely related to the prec...

There is a tremendous growth in the deployment and usage of Wireless Local Area Networks (WLANs) in recent years. There is also an increasing interest in supporting voice applications over WLANs. In this paper we use analytical models presented in the literature for saturation throughput, average packet delay and packet drop probability and simulative results for jitter to evaluate voice traffi...

Pulmonary function tests were performed at rest and following blood transfusion on 17 patients with thalassemia major. At rest, diffusion capacity was significantly reduced (mean of 57 percent), and forced vital capacity was mildly reduced (mean of 85 percent). In two of the patients, arterial oxygen tension was low. Other pulmonary function results were in the normal range. Following blood tra...

Optical burst switching (OBS) is a viable approach proposed with the objective of utilizing the huge transmission capacity available with WDM links both efficiently and cost effectively. In this paper simulation results for an OBS node with self-similar traffic comparing with drop history schemes, CTBR with the Horizon and the LAUC-VF scheduling algorithms clearly indicate their overall schedul...

Although from an athletic performance perspective it may be beneficial to undertake drop jump training when fatigued (principle of "specificity" of training), such endurance fatigue may expose the body to a greater risk of injury if it causes an increase in peak impact accelerations. This study aimed to determine if endurance fatigue resulted in an increase in tibial peak impact acceleration an...
