Abstract  

Waste management plays an important role in radioactive waste volume reduction as well as lowering disposal costs and minimizing the environment-detrimental impact. The employment of biomass in the removal of heavy metals and radioisotopes has a significant potential in liquid waste treatment. The aim of this study is to evaluate the radioactive waste treatment by using three different bacterial communities (BL, BS, and SS) isolated from impacted areas, removing radioisotopes and organic compounds. The best results were obtained in the BS and BL community, isolated from the soil and a lake of a uranium mine, respectively. BS community was able to remove 92% of the uranium and degraded 80% of tributyl phosphate and 70% of the ethyl acetate in 20 days of experiments. BL community removed 81% of the uranium and degraded nearly 60% of the TBP and 70% of the ethyl acetate. SS community collected from the sediment of São Sebastião channel removed 76% of the uranium and 80% of the TBP and 70% of the ethyl acetate. Both americium and cesium were removed by all communities. In addition, the BS community showed to be more resistant to radioactive liquid waste than the other communities. These results indicated that the BS community is the most viable for the treatment of large volumes of radioactive liquid organic waste.

I collected stories of conversion from university students in Kolozsvár/Cluj. They had come into contact with representatives of the revival movement and constructed their own identities under the influence of the identity patterns conveyed by these people. The conversion means that their relationship with God becomes personal in that they accept salvation from sin for themselves, declare themselves to be the children of God and place their lives under His guidance. This goes together with a new way of life involving daily reading and interpretation of the Bible, impromptu personal prayers and participation in charity work. In the stories of conversion they speak about this new identity and the process through which they changed their identities. Parallel with the restructuring of the individual identity the collective identity also changes since, from the time of their conversion, they regard themselves as members of the community and the activity of the community extends to all fields of life: Bible hours, religious services, sports, summer camps, film club, etc.

Introduction Urinary tract infections (UTIs) are among prevalent infections acquired both in community and in hospitals. It is estimated that 40% of women will have a UTI with a rate of 25% for recurrent UTIs [ 1 ]. Klebsiella

Abstract  

In invisible colleges the relative frequency of coauthorships is higher between scientists with the same number of publications than between authors of different ones. The opposite is valid in institutionalized communities.

Changes in species composition during the succession of ecological communities potentially reflect the differential effects of environmental filters and limiting similarity on structuring communities. As ecological succession can represent community assembly in action, understanding how successional time affects the functional and phylogenetic structure of communities can reveal the influence of different factors on the assembly process. We analysed functional patterns of multiple traits related to the succession of tropical forests to answer if there are trait convergence and/or divergence with regeneration age, and if functional and phylogenetic diversity can be predicted by forest age. We compiled checklists from studies of 23 successional forests in Brazilian Atlantic Forest, ranging from 4 to 120 years old. We also compiled functional traits for a total of 355 species. We analysed the data by a method that includes scaling-up trait-based data to the community level and matrix correlations of multiple traits. We built linear models to show the relationship between each trait and diversity (taxonomic, functional and phylogenetic) with successional time. We found no phylogenetic signal at the species pool and metacommunity levels, but significant trait divergence (tree guild, leaf slenderness, leaf area, pollination entomophilous generalist and pollination by vertebrate) and trait convergence (arboreal habitus, tree guild, leaf compoundness, pollination entomophilous generalist) patterns related to the successional gradient. Also, functional diversity increased during succession, with a significant increase in leaf slenderness and zoochoric dispersal and decrease in tree guild. Phylogenetic diversity also increased along the successional gradient. We found that the communities in the studied successional gradient are structured by both environmental (measured by trait convergence) and biotic (measured by trait divergence) filtering. The species turnover and diversification at taxonomic level are followed by well-defined patterns of trait turnover, revealing that community assembly is constrained by environmental filters at the beginning and by limiting similarity at the advanced stages of the succession.

Abstract  

Social network analysis is an important research tradition in structural sociology and has contributed much to our understanding of inter and intra organizational relations. Of particular significance is the contribution of social network analysis to the definition of community. Communities, whether traditional or scientific, can be effectively thought of as a series of positions and roles. This paper proposes four hypotheses about a select group of management scholars (laureates) and the network ties that connect them. Laureates were asked to identify individuals who had influenced their intellectual development and work in the management discipline. An invisible college in the traditional sense did not exist but rather a complex series of intellectual neighborhoods were identified. These neighborhoods, as contrasted to true communities or colleges were small, uncoordinated, and fragmented.
