an investigation was carried out to reveal the changes in the concentration of soluble carbohydrates under tuber dormancy in food yam (dioscorea esculenta) tubers and in an economically important spice cum medicinal plant turmeric (curcuma longa) rhizomes under storage. harvested, fully matured tubers of yam and rhizomes of turmeric were stored in wooden boxes under the conditions of 28 ? 2?c t...

Nowadays one of the most important energy sources is natural gas. By depletion of oil reservoirs in the world, natural gas will emerge as the future energy source for human life. One of the major concerns of gas suppliers is being able to supply this source of energy the entire year. This concern intensifies during more consuming seasons of the year when the demand for natural gas increases, r...

Renewable energy sources (RES), especially wind power plants, have high priority of promotion in the energy policies worldwide. An increasing share of RES and distributed generation (DG), should, as has been assumed, provide improvement in reliability of electricity delivery to the customers. Paper presented here concentrates on electricity storage systems technologies and applications pinpoint...

the effects of uv-c illumination at the dosage of 6.6 kj m-2 on postharvest quality of mango fruit cv. ‘kaew kamin’ during storage at 25 or 12°c were investigated. the changes in fresh weight, texture, ripening index (ri), peel and pulp colours, visual appearance, total carotenoids (tc) and ascorbic acid (asa) content were determined on days 0, 4, 8, 12 and 16 of storage. uv-c irradiation effec...

Native population of raspberry fruits (Rubus spp) were treated with Methyl Jasmonate (MJ) fumigation and were assayed for the antioxidant capacity, total anthocyanins and postharvest quality after 7 days storage at 4?C. The result of experiment revealed that berries treated with methyl jasmonate (MJ) showed higher antioxidant capacity and total anthocyanins compared to the controled ones (non...

sensitivity of tomato fruit to low temperature and chilling injury limits the storage, handling and marketability of the fruit. as a recommended postharvest treatment, effects of hot water treatment (hwt) on reducing chilling injury and quality traits, variation of tomato fruits during storage life were investigated. tomato fruits were harvested at mature green stage. they were treated by hot w...
