This work aims to verify the effects of natural structure a residual soil on its erodibility and potential, employing compaction, restore erosion resistance. It is gneiss that occurs in state Santa Catarina, Southern Brazil. Infrastructure earthworks expose this material action water, which can develop severe erosive features. The evaluation was made using MCT methodology based infiltrability m...
Physically based distributed hydrological models aim at an adequate representation of processes, including runoff generation. A significant proportion is generated through the subsurface, i.e. by groundwater flow or unsaturated subsurface stormflow. However, in case high rainfall intensity and/or low soil-surface infiltrability, surface may strongly contribute to total runoff, too, either satur...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...
Extensive deforestation in tropical regions may significantly influence the hydrological cycle. However, subsurface runoff processes thick soil layers humid forests are poorly understood; thus, impact of land-use changes such remains unclear. To understand generation mechanisms tropics, we monitored groundwater and moisture dynamics a forested hillslope Sumatra, Indonesia. We also conducted fie...
the aim of this study has been to find answers for the following questions: 1. what is the effect of immediate correction on students pronunciation errors? 2. what would be the effect of teaching the more rgular patterns of english pronunciation? 3. is there any significant difference between the two methods of dealing with pronuciation errore, i. e., correction and the teaching of the regular ...
