Computational Fluid Dynamics is used to investigate the global forces and moments acting on the KVLCC2 hull form under going straight line, drift and pure sway planar motion mechanism tests. Simulated results are compared with experimental results for the unappended hull in shallow water and a fully appended hull with a propeller acting at the ship self propulsion point. A body fitted mesh unde...

the initial step in any breeding program including the breeding of walnut is an evaluation of the genetic diversity of its population and on identification of its superior and promising genotypes. this research was carried out during 2009-2010 growing seasons to evaluate the walnut genotypes, population grown in the vicinities of eghlid city, as one of the richest walnut population regions in t...

Evidence suggests that dietary walnuts are able to induce improvements in memory and learning functions. In addition, polyphenols have been shown to modulate critical neuronal signalling pathways involved in processes of learning and memory. The aim of our present work was to study the effect of polyphenol extracts from walnut testa (42%) on learning and memory functions in hypercholesterolemia...

Although the walnut husk fly, Rhagoletis completa, is sometimes considered to be a weak flier, very little is known about the actual flight capacity of this fly. With funding from CDFA and CSU-ARI (California State University Agricultural Research Initiative), we initiated studies, in the laboratory and field, of flight capacity and dispersal ability of husk flies. Adult flies in the laboratory...

Temporal and spatial variations in the water status of walnut trees (Juglans regia L.) and the soil in which they were growing were traced by analyzing the differences in hydrogen isotopes during spring and summer in a 7-year-old walnut stand. Walnut root dynamics were measured in both dry and wet seasons. Walnut roots were mainly distributed in the upper soil (0-30 cm depth), with around 60% o...

OBJECTIVE To determine the effects of daily walnut consumption on endothelial function, cardiovascular biomarkers, and anthropometric measures in type 2 diabetic individuals. RESEARCH DESIGN AND METHODS This study was a randomized, controlled, single-blind, crossover trial. Twenty-four participants with type 2 diabetes (mean age 58 years; 14 women and 10 men) were randomly assigned to one of ...

BACKGROUND Optimal macronutrient distribution of weight loss diets has not been established. The distribution of energy from carbohydrate and fat has been observed to promote differential plasma lipid responses in previous weight loss studies, and insulin resistance status may interact with diet composition and affect weight loss and lipid responses. METHODS AND RESULTS Overweight and obese w...

English walnut (Juglans regia) has become an important crop in Chile, representing 11.5% of the total area fruit trees, surpassed only by grapevine. As Chilean industry rapidly expands, young orchards are at risk from emergence new fungal diseases. Botryosphaeriaceae and Diaporthaceae fungi have been recognized as main causes wood diseases walnut, with symptoms dieback, canker, blight. In winte...

The phenolic extracts of walnut cultivars with a red pellicle (HWE), purple (ZWE) and yellow (WWE) were compared. total contents phenolics, flavonoids condensed tannins, as well in vitro antioxidant activities (ABTS DPPH) the evaluated. results showed that 25 compounds identified three colored walnuts. HWE contained highest phenolics while ZWE content flavonoids. DPPH ABTS assays indicated colo...
