abstract soil organic matter and its components are important factors in formation and stability of aggregates and subsequently soil structure. however data regarding organic matter distribution in soil aggregates is scarce, particularly in arid soils of central iran. the objective of this study was to investigate the distribution of organic carbon (oc), total nitrogen (tn), and carbohydrates i...
Background and purpose: This study aimed at determining the relationship between the body mass index and pattern of fat distribution with blood lipid serum among secondary school girls. Materials and methods: A total of 780 students who volunteered to participate in this study signed an informed consent form. Among them 155 were active, 340 were inactive and 285 students were moderately active...
Abstract In the present study, the structure of macrobenthos communities of Chabahar Bay prior to monsoon in 2016 was investigated. We identified 87 species contain 22 amphipods species, 14 species of other crustaceans, 31 species of molluscs, and 20 polychaets species, where amphipods followed by polychates were dominant taxa. The PERMANOVA test revealed that there is a significant difference...
Background and purpose: Chloroform is a disinfection byproducts (DBPs) that results from reactions between residual chlorine and organic compounds as precursors. The presence of these DBPs in chlorinated drinking water can pose a severe public health threat including potential carcinogenicity. In this study chloroform concentrations as an indicator of DBPs of chlorinated water was evaluated in ...
The forest ecosystem is the largest land vegetation type, which plays the role of unreplacement with its unique value. And in the landscape scale, the research on forest landscape pattern has become the current hot spot, wherein the study of forest canopy structure is very important. They determines the process and the strength of forests energy flow, which influences the adjustments of ecosyst...
Confined spatial patterns of microbial distribution are prevalent in nature, such as in microbial mats, soil communities, and water stream biofilms. The symbiotic two-species consortium of Pseudomonas putida and Acinetobacter sp. strain C6, originally isolated from a creosote-polluted aquifer, has evolved a distinct spatial organization in the laboratory that is characterized by an increased fi...
