Finite groups have even more centralizers
For a finite group $G$, let $Cent(G)$ denote the set of centralizers of single elements of $G$. In this note we prove that if $|G|leq frac{3}{2}|Cent(G)|$ and $G$ is 2-nilpotent, then $Gcong S_3, D_{10}$ or $S_3times S_3$. This result gives a partial and positive answer to a conjecture raised by A. R. Ashrafi [On finite groups with a given number of centralizers, Algebra Collo...
متن کاملPatterns in Benthic Biodiversity Link Lake Trophic Status to Structure and Potential Function of Three Large, Deep Lakes
Relative to their scarcity, large, deep lakes support a large proportion of the world's freshwater species. This biodiversity is threatened by human development and is in need of conservation. Direct comparison of biodiversity is the basis of biological monitoring for conservation but is difficult to conduct between large, insular ecosystems. The objective of our study was to conduct such a com...
متن کاملWithin-lake variability of subfossil chironomid assemblage in a large, deep subtropical lake (Lugu lake, Southwest China)
The present study analysed the distribution of subfossil chironomid larval head caspules in a suite of surface sediment samples from a large deep subtropical lake, i.e. Lugu lake, located in Southwest China. In order to identify the relationships between environmental variables and the chironomid assemblages ordination methods were used. A total of 41 chironomid taxa were found across the 46 sa...

متن کاملNutrient dynamics of Lake Tanganyika
The large and productive fishery of Lake Tanganyika is an important source of income and nutrition for the surrounding areas. This fishery, based primarily on pelagic clupeids (Kiswahili: dagaa), is very productive, and provides a readily available, nutritious, and inexpensive source of protein to the rapidly growing human populations in this area. The regional importance of the Lake Tanganyika...
