Understanding the variability of pedological properties as well as the soil quality attributes on different landscape positions in hummocky terrains would result in a better land management in such areas. Despite the importance of such studies, no research has been couducted on the landscape-scale variability of soil quality indices in Iran and most researchers have so far focussed on pedologic...

as far as bandura’s (1977) conceptualization of the sense of self-efficacy is concerned, it is argued to be context- and even task-specific, compared to other concepts like self-esteem (brown, 2000); therefore, upon the previous research studies, related theories and definitions, and the ideas and views obtained from the interviews conducted with the scholars, the current research study aimed a...

South Carolina, despite being a small state, possesses a wide range and diversity of hydrogeologic conditions, generally arranged into geologic belts or physiographic provinces. These distinct areas range from the mountains and piedmont with crystalline metamorphic and igneous rocks with major geologic structural features, to a broad coastal plain with sand and limestone aquifers (Fig. 1). Acco...

I. ABSTRACT Fire can play a significant role in runoff, sediment yield and nutrient transport from aquatic and terrestrial ecosystems in the southeast US. Hydrologic and nutrient cycling interactions with fire are likely to vary considerably across the physiographic regions of the southern U.S.; however, there have been few large comparative studies. Our approach was to combine field measuremen...

abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...

Tillage system effect, Conventional (CT) vs. No-Till (NT), on soil physical properties and Br transport was studied at two locations in North Carolina. The soil types were a Typic Paleudults at Coastal Plain (site 1) and a Typic Kanhapludults at Piedmont (site 2). Bulk density (BD), total porosity (TP), macroporosity (MP), and saturated hydraulic conductivity (Ks) .were measured in plant row (R...
