1. Inducible cellulase production from an organic solvent tolerant Bacillus sp. SV1 and evolutionary divergence of endoglucanase in different species of the genus Bacillus
Abstract Bacteria are important sources of cellulases with various industrial and biotechnological applications. In view of this, a non-hemolytic bacterial strain, tolerant to various environmental pollutants (heavy metals and organic solvents), showing high cellulolytic index (7.89) was isolated from cattle shed soil and identified as Bacillus sp. SV1 (99.2

2. Searching for convergent evolution in manganese superoxidase dismutase using hydrophobic cluster analysis
There are numerous examples of convergent evolution in nature. Major ecological adaptations such as flight, loss of limbs in vertebrates, pesticide resistance, adaptation to a parasitic way of life, etc., have all evolved more than once, as seen by their analogous functions in separate taxa. But what about protein evolution? Does the environment have a stron

3. Diversidade de estratégias ecológicas das espécies de árvore dominantes de uma floresta de terra firme da Amazônia Central / Diversity of ecological strategies of the dominant tree species from a terra-firme forest in Central Amazonia
As plantas têm diversos modos de resolver problemas como a escassez de recursos, o ataque de herbívoros ou a perda de água. O modo como uma planta resolve um desses problemas pode ser considerado uma tática e o conjunto dessas táticas constitui uma estratégia ecológica. As estratégias só são possíveis porque as plantas têm uma série de atributos

4. The EG95 antigen of Echinococcus spp. contains positively selected amino acids, which may influence host specificity and vaccine efficacy
Echinococcosis is a worldwide zoonotic parasitic disease of humans and various herbivorous domestic animals (intermediate hosts) transmitted by the contact with wild and domestic carnivores (definitive hosts), mainly foxes and dogs. Recently, a vaccine was developed showing high levels of protection against one parasite haplotype (G1) of Echinococcus granulo

5. A música sacra em duas igrejas evangélicas do DF : estudo analítico sobre a retratação da música cristã tradicional ante o avanço da música cristã contemporânea
This work provides a brief evolution of music in the Christian church highlighting its characteristic trends since the Protestant Reform of the 16th century. Emphasizes the educational role of music in church as a means to teach and spread the doctrine of the apostles with psalms and hymns containing the truths of the Christian faith; lyrics and music become

6. Filogenia do complexo Caladieae-zomicarpeae (araceae) baseada em seqüências do DNA plastidial
The complex Caladieae-Zomicarpeae is composed by the genera Zomicarpa, Zomicarpella, Ulearum, Filarum, Hapaline, Scaphispatha, Caladium, Jasarum, Xanthosoma, Chlorospatha and Syngonium. The complex has an essentially Neotropical distribution, with the sole exception of the Asian genera Hapaline. The group contains elements of moderate economic importance, as

7. Estudo crítico do pronunciamento conceitual básico "Estrutura Conceitual para Elaboração e Apresentação das Demonstrações Contábeis" emitido pelo Comitê de Pronunciamentos Contábeis (CPC)
The history of the evolution of accounting, so overall, shows the relationship between the development of accounting knowledge and the environmental characteristics (political, economic, cultural and institutional). With the development and opening economic markets, the accounting is now considered the financial language of business. From then on, trying to

8. Study of evolution of zinc phosphate cement´s setting reaction by laser, applying an optics technique of dynamic speckle / "Estudo da evolução da reação de presa do cimento de fosfato de zinco através de luz laser, aplicando a técnica óptica de speckle dinâmico"
The prosthesis cementation and/or other prosthetic elements, consists in permanent concern, since one of the major applications of zinc phosphate cement is as lutting agent. This study aims at the microstructural analyze to the evolution of the zinc phosphate cement´s setting reaction. More specifically, searched to verify, based on the known phenomenon as

12. Comparative Analysis of Gene Expression for Convergent Evolution of Camera Eye Between Octopus and Human
Although the camera eye of the octopus is very similar to that of humans, phylogenetic and embryological analyses have suggested that their camera eyes have been acquired independently. It has been known as a typical example of convergent evolution. To study the molecular basis of convergent evolution of camera eyes, we conducted a comparative analysis of ge
