1. Efeitos dos Softwares de Análise de Dados Qualitativos na Qualidade de Pesquisas
Resumo O objetivo deste estudo é descrever os efeitos dos softwares de análise de dados qualitativos (Qualitative Data Analysis Software [QDAS]) na qualidade das pesquisas qualitativas, segundo a perspectiva de pesquisadores. O que motivou esta pesquisa foi a divergência de opiniões com relação aos efeitos dos QDAS na qualidade das pesquisas qualitativ

2. Filogenia do Complexo Drosophila Buzzatii (Grupo Repleta): Inferências de Análises Multilocus Mitocondriais e Nucleares. / Phylogeny of Drosophila buzzatii Complex (Repleta Group): Inferences from Mitochondrial and Nuclear Multilocus Analysis.
O complexo Drosophila buzzatii (grupo repleta) compreende 13 espécies, divididas em três clusters, de acordo com o bandeamento observado nos cromossomos politênicos: cluster D. stalkeri, incluindo D. richardsoni e D. stalkeri, restrito às ilhas do Caribe e Flórida; cluster D. martensis, incluindo D. martensis, D. uniseta, D. venezolana e D. starmeri, en

3. In vitro and in vivo electrochemical studies of nickel-chromium-molybdenum-titanium alloy applied to oral implant suprastructures / Estudos eletroquímicos in vitro e in vivo da liga níquelcromomolibdênio titânio aplicada em supraestruturas de implantes orais
The electrochemical behavior of the nickel-chromium-molybdenum-titanium (Ni-Cr-Mo-Ti) alloy was studied and compared to a gold-platinum-palladium (Au-Pt-Pd) alloy in 0.15 mol.L -1 NaCl medium at 36.5ºC. In vitro studies also involved the electrochemical titanium characterization since these alloys are employed in osseointegrated implant suprastructures. In

4. Slow-growing Rhizobium japonicum comprises two highly divergent symbiotic types.
We examined the interrelationships of the genomes of 10 slow-growing strains of Rhizobium japonicum to provide a foundation for molecular genetic studies of these agriculturally important endosymbiotic bacteria of commercial soybeans. The degree of base substitution in and around known symbiotic genes (nif and presumptive nod), constitutively expressed genes

5. Unusual plasmid DNA organization in an octopine crown gall tumor.
A cloned tobacco crown gall tumor, 1595501, incited by A. tumefaciens strain 15955 was studied. Molecular analysis of the organization of the T-DNA by means of Southern transfer and hybridization techniques indicated that the 1595501 tumor has about 10 copies of TL DNA, five of which are complete TL DNA, whereas most octopine tumors have only one to two copi

6. Variable efficiency of a Ti plasmid-encoded VirA protein in different agrobacterial hosts.
The transconjugant CB100, harboring the Ti plasmid from the Agrobacterium tumefaciens biovar 2 strain D10B/87 in the chromosomal background of the biovar 1 strain C58, was defective in vir gene induction. This defect was corrected in the presence of virA from pTiA6. Based on this complementation result and an analysis of the induction requirements of the tra

7. The phylogeny of closely related species as revealed by the genealogy of a speciation gene, Odysseus
Molecular differentiation between races or closely related species is often incongruent with the reproductive divergence of the taxa of interest. Shared ancient polymorphism and/or introgression during secondary contact may be responsible for the incongruence. At loci contributing to speciation, these two complications should be minimized (1, 2); hence, thei

8. Gene duplication and speciation in Drosophila: Evidence from the Odysseus locus
The importance of gene duplication in evolution has long been recognized. Because duplicated genes are prone to diverge in function, gene duplication could plausibly play a role in species differentiation. However, experimental evidence linking gene duplication with speciation is scarce. Here, we show that a hybrid-male sterility gene, Odysseus (OdsH), arose
