In this study, the effects of vacuum infusion configuration on homogeneities glass fiber reinforced vinyl ester composites have been evaluated. Three different sizes samples (100x100, 500x500, and 1000x1000 mm) were fabricated. configurations used to fabricate samples. The first two had one inlet, while third inlets for resin infusion. Thickness variations hardness (Shore D) measurements perfor...

Co-flows model a modern scheduling setting that is commonly found in a variety of applications in distributed and cloud computing. In co-flow scheduling, there are m input ports and m output ports. Each co-flow j ∈ J can be represented by a bipartite graph between the input and output ports, where each edge (i, o) with demand dji,o means that d j i,o units of packets must be delivered from port...

The effectiveness of a three-dimensional mixed-flow turbulence model describing airspeed and temperature distribution in a laboratory scale slot-ventilated chamber was evaluated. Airspeed and temperature profiles were investigated near the inlet jet region and along an axial line extending from the inlet. The observed jet-floor impingement location was accurately predicted^ with a maximum diffe...

The objective of this study was to evaluate the feasibility of an aqueous process to extract the residual oil from sunflower press cakes using a co-rotating twin-screw extruder. Two different configurations were tested: the expression fromwhole seeds followed by the aqueous extraction, in two successive apparatus or in the same one. For the aqueous extraction stage, the oil yield depended on th...

In this research, a CFD solver is developed for solving the 2D/3D compressible flow problem: finite volume method based on multi-block structural grids used to solve Reynolds averaged Navier–Stokes equations (RANS). Included in methodology are multiple high-order reconstruction schemes, such as 3rd-order MUSCL (Monotone Upstreamcentered Schemes Conservation Laws), 5th-order WENO (Weight Essenti...

Hydrodynamics analyses as a part of the APEX (advanced power extraction) study demonstrates the potential application of applying swirling thick liquid walls to innovative confinement concepts such as field reversed configuration (FRC), spherical torus (ST) and heavy-ion fusion (HIF). This paper addresses the design and the hydrodynamic aspects of fusion relevant swirling flow including 3-D vel...

Implantable ports are used for intravenous infusion therapy and play an important role in management of oncology patients. These ports are best suited for patients requiring long-term therapy (>4 weeks). Implanted ports provide reliable venous access protect peripheral access increase patients’ comfort through reducing repeated and difficult vein punctures allow for safe and comfortable admi...

Tsunami-induced currents present an obvious hazard to maritime activities and ports in particular. The historical record is replete with accounts from ship captains and harbour masters describing their fateful encounters with currents and surges caused by these destructive waves. Despite the well-known hazard, only since the trans-oceanic tsunamis of the early twenty-first century (2004, 2010 a...

Internal combustion engines in now a days is the best available reliable source of power for all domestic, large scale industrial and transportation applications. The major issue arises at the efficiency of these engines. Every attempt made to improve these engines tends to attain the maximum efficiency. The performances of the diesel engines are enhanced by proper design of inlet manifold, exh...

Abstract Background Totally implantable central venous access devices (ports) have been available for over 10 years, but have not been achieved widespread use in pediatric oncology patients. Ports facilitate the administration of chemotherapy in children with cancer. Materials and Methods In this study, early complications of implantable central venous access devices in children with diff...
