The dietary consumption of grape and its products is associated with a lower incidence of degenerative diseases such as cardiovascular disease and certain types of cancers. Most recent interest has focused on the bioactive phenolic compounds in grape. Anthocyanins, flavanols, flavonols and resveratrol are the most important grape polyphenols because they possess many biological activities, such...

The two-spotted spider mite, Tetranychus urticae Koch, has caused significant damage to vineyards in the valley of São Francisco River Brazil. Neoseiulus idaeus Denmark & Muma is one most abundant species predatory mites on vines this region. This study evaluated population growth rates T. leaves two grape (Vitis vinifera L.) cultivars (‘Italia’ and ‘Superior Seedless’) jack bean [Canavalia ens...

We overview the GRAPE-6 project, a follow-up of the ter-aaops GRAPE-4 project. GRAPE-6 will be completed by 1999-2000 and its planned peak speed is 200 TTops. Its architecture will be largely similar to that of GRAPE-4, which is a specialized hardware to calculate the gravitational interaction between particles. The improvement in the speed will come mainly from the advance in the silicon semic...

Grapes are one of the most widely grown fruits and have been used for winemaking since the ancient Greek and Roman civilizations. Grape seeds are rich in proanthocyanidins which have been shown to possess potent free radical scavenging activity. Grape seeds are a complex matrix containing 40% fiber, 16% oil, 11% proteins, and 7% complex phenols such as tannins. Grape seeds are rich sources of f...

Grape metabolites can be affected by many extrinsic and intrinsic factors, such as grape variety, ripening stage, growing regions, vineyard management practices, and edaphoclimatic conditions. However, there is still much about the in vivo formation of grape metabolites that need to be investigated. The winemaking process also can create distinct wines. Nowadays, wine fermentations are driven m...

The aim of this research is to improve an existing low-cost and simple but consistent culturing technique for measuring the adsorption of grape skin pigments on yeasts, comprising: (i) growing yeasts in Petri dishes on chromogenic grape-skin-based medium, (ii) photographing the yeast biomass, (iii) measuring its red, green, and blue colour components, and (iv) performing the statistical analysi...

Most convolutional neural network (CNN) models have various difficulties in identifying crop diseases owing to morphological and physiological changes tissues, cells. Furthermore, a single disease can show different symptoms. Usually, the differences symptoms between early late stages include area of color disease. This also poses additional for CNN models. Here, we propose lightweight model ca...
