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...

Increasing pollution has significantly threatened the Antarctic ecosystem. The contamination of hydrocarbons drawn a considerable amount attention owing to their toxicity, recalcitrance, and persistence. Considering Treaty, only indigenous species are allowed bioremediate contaminated environment. However, knowledge ecological role, physiology, function, genomics endemic hydrocarbon consumers i...

Cyanobacteria are photosynthetic, gram negative, and diverse group of prokaryotic organisms, inhabiting a wide range habitats including caves. This study was aimed to isolate identify cyanobacteria in selected caves Bulabog Putian National Park, Dingle, Iloilo, Western Visayas, Philippines. Based on morphology 16S rRNA gene sequence analysis six strains were identified. The homology search by B...

A b s t r a c t In this paper, we briefly discuss the dynamic and functional approach to computer symbolic tensor analysis. The ccgrg package for Wolfram Language/Mathematica is used to illustrate this approach. Some examples of applications are attached.

In this article, we propose a fuzzy class relation assigning to each pair of finite fuzzy sets a degree to which they are equipollent, which indicates that they have the same number of elements. The concepts of fuzzy sets and fuzzy classes in the class of all countable sets are introduced, and several standard relations and constructions, such as the fuzzy power set and exponentiation, are defi...
