GRAPE (GRavity PipE) processors are special purpose computers for simulation of classical particles. The performance of MD-GRAPE, one of the GRAPEs developed for molecular dynamics, was investigated. The effective speed of MD-GRAPE was equivalent to approximately 6 Gflops. The precision of MD-GRAPE was good judging from the acceptable fluctuation of the total energy. Then a software named PEACH...

Grape seeds represent a high percentage (20% to 26%) of the grape marc obtained as a byproduct from white winemaking and keep a vast proportion of grape polyphenols. In this study, seeds obtained from 11 monovarietal white grape marcs cultivated in Northwestern Spain have been analyzed in order to characterize their polyphenolic content and antioxidant activity. Seeds of native (Albariño, Caiño...

The purpose of present study was to investigate the effect of water and ethanol extracts of red grape seeds on inhibition of pancreatic -amylase and lipase in vitro. Total proanthocyanidins were determined in grape seed extracts (GSEs). Different concentrations (400, 800, 1300 and 1800 ppm) of each GSE were employed to evaluate their potentials on pancreatic -amylase and lipase after pre-incuba...

Rain-shelter cultivation is an effective cultural method to prevent rainfall damage during grape harvest and widely applied in the Chinese rainy regions. In this study we investigated the effect of rain-shelter cultivation on grape diseases and phenolic composition in the skins of Vitis vinifera cv. Cabernet Gernischet grape berries through the comparison with open-field cultivation at two vint...

This study was conducted to investigate the effect of dietary grape skin on lipid peroxidation and antioxidant defense system in rats fed high fat diet. The Sprague-Dawley rats were fed either control (5% fat) diet or high fat (25% fat) diet which was based on AIN-93 diet for 2 weeks, and then they were grouped as control group (C), control + 5% grape skin group (CS), high-fat group (HF), high ...

The effect of 2% grape seed and 2% grape skin powder added to chicken thigh patties stored at 4°C was assessed by measuring lipid oxidation, total phenolic content, pH, color changes and sensory attributes. The addition of these grape by-products to the patties lowered pH values and significantly reduced in lightness, redness and yellowness compared with the control. However, the addition of gr...

To understand the adaptation of grape rootstocks commonly used in major grape production areas worldwide to Florida, where Pierce’s dsease (PD) is the primary limiting factor in grape production, ten important grape rootstocks were cultivated at the experimental vineyard, Florida A&M University, Tallahassee, Florida. Disease resistance and symptoms and growing performance were evaluated. PD sym...

We present Particle–Particle–Particle–Mesh (PPPM) and Tree Particle–Mesh (TreePM) implementations on GRAPE-5 and GRAPE-6A systems, special-purpose hardware accelerators for gravitational many-body simulations. In our PPPM and TreePM implementations on GRAPE, the computational time is significantly reduced compared with the conventional implementations without GRAPE, especially under the strong ...
