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...
The service industry has become increasingly important in our daily lives and global economies, and improving service quality will have a significant social and economical impact. The massive amount of data readily available provides us with opportunities to integrate advanced statistical methodologies with system knowledge to better model and control the quality of service systems. Monitoring ...
Recently much attention has been paid by horticulturists to light-emitting diodes as a new source of economical and spectral-selective light. The reason is mainly coming from their versatility in handling and mounting, long working time, wattage use efficiency and lower heat production. In this study we examined their potential in promoting seed germination and producing quality flower seedling...
The stability of radiance measurements taken by the Sky Quality Meter (SQM)was tested under rapidly changing temperature conditions during exposure to a stable light field in the laboratory. The reported radiance was found to be negatively correlated with temperature, but remained within 7% of the initial reported radiance over a temperature range of -15 °C to 35 °C, and during temperature chan...
beyond its quantity, natural light has unique properties used intelligently in iranian historical architecture in order to transfer spiritual concepts. religious buildings are a good context for re-reading of light concept. due to its valuable place in iranian-islamic belief as well as its direct relationship with wisdom and philosophy, the qualitative presence of light in architecture, aimed a...
