Wet friction clutches have become widely used in today’s transmissions, e.g. automatic transmissions, dual clutch transmissions, etc. It is known that the central role of this particular component is strongly determined by its friction characteristics. While a clutch is in use, degradation inevitably takes place that consequently deteriorates its friction characteristics. However, to the author...

Thua nao was a Thai alkali fermented product from soybean by Bacillus and it had a special flavour and aroma. The microorganisms involved in traditional thua nao were mixed natural flora of Bacillus, B. subtilis, B. megaterium and B. cereus, contaminated from cooked soybeans. The product had a very strong smell of ammonia. Ammonia content in dried product was lower than in the wet product. The ...

With the improvement of the urbanization level, the mixed city water has surged and the traditional denitrogenating cost in the course of wastewater reuse has been unbearable. This experiment used the technology of the constructed rapid infiltration (CRI) and applied the soil column simulation method in the laboratory. The results show that nitrogen removal rates of two soil columns are 73.73% ...

Species of the woody root rot fungus Armillaria are indigenous in cool temperate rain forest, mixed forest, and wet and dry sclerophyll eucalypt forests in Australia. Four species have been described or identified from southeastern Australia: A. luteobubalina Watling and Kile, A. fumosa Kile and Watling, A. hinnulea Kile and Watling, and A. novae-zelandiae (Stevenson) Boesewinkel. The latter sp...

The lower montane zone of northwestern Ecuador, like many parts of the tropics, is undergoing rapid conversion from native forest vegetation to crop and pastureland. The current landscape is a mosaic of agricultural land, forest fragments and secondgrowth vegetation in various stages of development. While there is abundant research documenting the e€ects of land-use change in the lowland tropic...

The mixed-wet nature of reservoir formations imposes a wide range rock wettability from strong resident-fluid wetting to invading-fluid wetting. characteristics two-phase flow in porous media composed mixed-wetting surfaces remain poorly understood. In this study, we investigated the displacement resident ethylene glycol (EG) by hexane two micromodels identical 2.5-D geometry heterogeneity, wit...
