ویژگی های زمین شیمیایی، کانی شناسی، و میکرومورفولوژیکی خاک ها و سنگ مادر مربوطه در منطقه بین بخش های جنوبی زاگرس و خلیج فارس تا دریای عمان(استان هرمزگان، ایران) مورد بررسی قرار گرفت. هدف های این مطالعه شناسایی تغییرات در خصوصیات فیزیکی، شیمیایی، و ترکیب کانی شناسی خاک، مطالعه میکرومورفولوژی و تکامل خاک، و بررسی توزیع عنصر خاک بر اساس هوازدگی، پروسه های خاک و زمین شناسی جهت توصیف اثرات مواد مادر...

The Bio-chemical Activity of Soils

Introduction Many methods have been devised in order to obtain a picture of the relatively broad spectrum of microorganisms present in the soil (Waksman, 1932; Lohnis, 1938 ; Beijerinck, 1946 ; Winogradsky, 1949). Techniques for direct microscopic examination, including contact slide methods, were developed by a number of research workers (Rossi, 1921, 1936; Conn, 1928, 1929 ; Cholodny, 1930; K...

Satellite Earth observation data to identify anthropogenic pressures in selected protected areas

Protected areas are experiencing increased levels of human pressure. To enable appropriate conservation action, it is critical to map and monitor changes in the type and extent of land cover/use and habitat classes, which can be related to human pressures over time. Satellite Earth observation (EO) data and techniques offer the opportunity to detect such changes. Yet association with field info...

Using spatial analysis to identify areas vulnerable to infant mortality.

OBJECTIVE To analyze the spatial distribution of infant mortality and identify clusters with high risk of death in the first year of life. METHODS The Thiessen (Voronoi) polygon method was used to analyze spatial distribution of the infant mortality rate, calculated by municipality. The triennium 2006 - 2008 was used as a reference to estimate the average infant mortality rate, and the first ...

Applying GC-MS analysis to identify chemical composition of Iranian propolis prepared with different solvent and evaluation of its biological activity

Soils of Amazonia with particular reference to the RAINFOR sites

The tropical forests of the Amazon Basin occur on a wide variety of different soil types reflecting a rich diversity of geologic origins and geomorphic processes. We here review the existing literature about the main soil groups of Amazonia, describing their genesis, geographical patterns and principal chemical, physical and morphologic characteristics. Original data is also presented, with pro...
