Volcanic activity has a significant influence on the development of terrestrial ecosystems, including Kamchatka Peninsula. We aimed to study algoflora Mutnovsky and Gorely volcanoes based use clonal cultures algae cyanobacteria, phenotypic molecular genetic analyses. A total 48 taxa were identified: 9 32 Chlorophyta (11 Chlorophyceae, 21 Trebouxiophyceae), 3 Ochrophyta, 4 Charophyta. In soils v...
Culturing, isolation, purification, and identification of cyanobacteria collected from wheat field soil, in five stations around the industrial areas in Yazd province (Iran) were conducted in this study. Identification of taxa was based on morphology and molecular methods. Cluster analysis and principal component analyses performed using SPSS software and rate of resemblance among the taxa were...
antifungal and antibacterial activity of some heterocystous cyanobacteria from paddy-fields in the north of iran was studied. soil samples were collected from paddy-fields of gillan, mazandaran and golestan provinces and cyanobacteria were isolated. supernatants, methanolic and hexane extracts from biomass of 150 strains of cyanobacteria were isolated and screened against six strains of bacteri...

One of the most important functions of the skin is to protect against various stressors. Environmental stimuli such as UV and environmental pollution increase reactive oxygen species and cause wrinkles and skin aging. Skin aging is associated with decreased collagen production and decreased activity of enzymes involved in collagen structure. Moisturizing chemicals increase the skin's ability to...
a large number of single research studies on the effects of strategy-based instruction (sbi) in teaching english as a foreign or second language has been conducted so far. however, the lack of a comprehensive meta-analysis targeting the effectiveness of english language sbi is observed. moreover, the findings of experimental studies regarding the context of the english language, proficiency lev...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
in this paper, the metazoan parasite community system of capoeta damascina in the tigris basin (mesopotamian region) in the middle-east is presented. overall, 54 species have been identified. between 2005 and 2008, iranian surveys of capoeta damascina found a total of 47 metazoan parasites species, most identified to species level. in addition, 6 parasite species from iraq and 1 species from oc...
in this study, calcareous nannofossils at the boundary between tirgan and sarcheshmeh formations at taherabad and mozduran sections have been studied. these sections are located in the eastern kopet-dagh basin. 22 nannoplankton species of 14 genera in taherabad section and 20 species of 14 genera in mozduran section were identified. according to the first occurrence of index species and fossil ...
