Limits on Efficient Computation in the Physical World

Date palm fruit is consumed as fresh fruit or processed to produce date paste and date syrup. Date syrup (DS) a natural sweetener contains mainly glucose and fructose and used with different food products. The effect of substituting sucrose with different level of DS (0, 25, 50 and 100%) on the physiochemical and sensory properties of ice cream were investigated. The overrun increased with incr...

Abstract Advances in sensor miniaturization are increasing the global popularity of unmanned aerial vehicle (UAV)-based remote sensing applications many domains agriculture. Fruit orchards (the source fruit industry chain) require site-specific or even individual-tree-specific management throughout growing season—from flowering, fruitlet development, ripening, and harvest—to tree dormancy. The ...

In this study, the aim is to develop a population model based approach to optimize fruit harvesting strategies with regard to fruit quality and its derived economic value. This approach was applied to the case of tomato fruit harvesting under Vietnamese conditions. Fruit growth and development of tomato (cv. "Savior") was monitored in terms of fruit size and color during both the Vietnamese win...

increasing product marketability and introduction of new cultivars for fresh consumption of apple is the world's most important breeding objectives. in this study, the qualitative and quantitative characteristics of the genotypes from cross between red spur and golab-e-kohanz apple cultivars were evaluated. a total of 19 traits including fruit attributes (firmness, fruit weight,...) and th...

Background Observational evidence suggests that intake of fruits, and of dietary antioxidants would be protective against symptoms and severity of asthma in children. Intervention studies with single or combined antioxidant supplements have so far been disappointing. To date, there have been no interventions using fresh fruit on asthmatic children. We plan to carry out a 3 month randomised cont...

Background & Aim: Strawberry (Fragaria vesca L.) is a plant belonging to the Rosaceae family with medicinal properties, including antioxidant activity. The present study aimed at investigating the antioxidant properties of strawberry. Experimental method: To examine the antioxidant effect, fruit extracts at two phonological stages of growth (ripe and unripe strawberry) were prepared. ...

Bunch thinning is one of the main cultural practices that enhance fruit quality. Hand thinning of date palm bunches is tedious and can not be implemented on a large scale. In this study, the cytokinin derivative CPPU [Nchloro4 pyridyl) N-phenyl urea] and fine mist of water were used 2 days prior pollination as thinning agent via reducing fruit set of Barhi and Lulu cultivars in two separate stu...

In the present study, the production of dextran from date extract and sucrose as carbon sources by the bacterium Leuconostoc mesenteroides NRRL B512 (f) was investigated. In comparison to blue dextran (Mw≈2000 Da), dextran molecular weight was reduced (Mw2000 KDa). Flow behavior indices of dextran solutions from date extracts were investigated and rheological parameters were evaluated at concen...
