Effects of runoff harvesting through semi-circular bund on some soil characteristics
In this study, to investigate the effects of runoff harvesting on soil properties in the semiarid forest, runoff harvesting through semi-circular bund was considered as a method to conserve soil and thereby combat tree mortality. In order to evaluate this hypothesis, runoff was harvested through the semi-circular bund affecting soil quality and moisture storage. The selected forest site is loca...
متن کاملOccurrence of cytophagas in sewage plants.
With the application of plate count methods and of the KOH-flexirubin test, bacteria belonging to the Cytophaga group were proved to occur regularly in samples from biological sewage treatment facilities. Generally, the percentage of Cytophaga colonies of the total heterotrophic colonies was lowest in the inflow sewage water as compared with the values found in activated sludge, trickling filte...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

متن کاملA preliminary spatial-temporal study of some soil characteristics in the calcareous massif of Sicó, Portugal.
The mountainous massif of Sicó, in the centre of Portugal, is an extensive area composed of calcareous Jurassic formations. Hillside calcareous soils, with high pH, present chemical restrictions to support plant growth and are subjected to important erosion processes leading to their degradation if not protected by vegetation. In a first year of study some soil physicochemical characteristics h...
