This paper presents a novel high performance computational (HPC) framework for multidisciplinary design optimization (MDO) of aero-craft shapes by using “Grid computing” technology. In this HPC framework, MDO computation is completed by using a genetic algorithm based optimization code and some performance evaluation codes. All those codes in the HPC system are named as “Grid Services” independ...

Haemangiopericytoma (HPC) is a rare vascular tumor with borderline malignancy, considerable histological variability, and unpredictable clinical and biological behavior. HPC can present a diagnostic challenge because of its indeterminate clinical, radiological, and pathological features. HPC generally presents in adulthood and is equally frequent in both sexes. HPC can arise in any site in the ...

Acquired memory initially depends on the hippocampus (HPC) for the process of cortical permanent memory formation. The mechanisms through which memory becomes progressively independent from the HPC remain unknown. In the HPC, adult neurogenesis has been described in many mammalian species, even at old ages. Using two mouse models in which hippocampal neurogenesis is physically or genetically su...

The synthesis of highly porous carbon (HPC) materials from poplar catkin by KOH chemical activation and hydrothermal carbonization as a conductive additive to a lithium-sulfur cathode is reported. Elemental sulfur was composited with as-prepared HPC through a melt diffusion method to form a S/HPC nanocomposite. Structure and morphology characterization revealed a hierarchically sponge-like stru...

Concrete has been prestressed traditionally with high-strength steel. The vulnerability of such material to corrosion calls for alternate materials, if thin-sheet products are to be prestressed. A research project at Columbia University is investigating the feasibility of using aramid fiber mesh for such purpose. This paper explores the chemical and mechanical properties of aramid in the form o...

Cellulose based polymers have shown tremendous potential as drug delivery carrier for oral drug delivery system (DDS). Hydroxyethyl cellulose (HEC) and hydroxypropyl cellulose (HPC) are widely explored as excipients to improve the solubility of poorly water soluble drugs and to improve self-life of dosage form. This work is an attempt to modulate the physicochemical properties of these cellulos...

abstract aims: one of the consequences of taking ground water into surface is changing its chemical quality, specially increasing the concentration of dissolved salts. this research was performed in order to analyze growth possibility of heterotrophic bacteria in the membrane of active desalination plants in kashan city, iran. instrument & methods: this descriptive cross-sectional study was don...
