Heat exchangers are commonly used in industrial fields such as air conditioning, petrochemical and agriculture-food industries. The design and utilization of a heat exchanger should fulfill some conditions of performance, economy and space requirement. The most widely operated heat exchangers make use of fin-and-tube configuration in association with the application of heating, ventilating, air...
Downy mildew is currently the most serious disease of sweet basil around the world. The oomycete causal agent Peronospora belbahrii requires ≥ 4h free leaf moisture for infection and ≥7.5h of water-saturated atmosphere (relative humidity RH≥95%) at night for sporulation. We show here that continued nocturnal fanning (wind speed of 0.4-1.5 m/s) from 8pm to 8am dramatically suppressed downy milde...
A flax fiber pilot plant is needed to process small samples of flax straw into fibers to facilitate research on retting and fiber properties. Our objective was to develop and test a modular design for a flax processing pilot plant based on a commercial line that was capable of cleaning fiber and seed flax straw from unretted, dew-retted, and enzyme-retted samples. The USDA Flax Fiber Pilot Plan...
Cucumis melo fruit is highly valued for its sweet and refreshing flesh, however the flavour and value are also highly influenced by aroma as dictated by volatile organic compounds (VOCs). A simple and robust method of sampling VOCs on polydimethylsiloxane (PDMS) has been developed. Contrasting cultivars of C. melo subspecies melo were investigated at commercial maturity: three cultivars of var....
Dew water condensation is due to the radiative cooling of a surface and hence promoted on surfaces with high emissivity in IR spectrum. The search for enhanced properties usually carried out without considering contribution condensation. On condensing substrate, however, droplets can occupy more than 55 % surface. Given (∼ 0.98), condensed thus expected modify efficiency. present study aims inv...
