1. Investigation of dormancy and storage potential of seeds of yellow passion fruit
Resumo: Passiflora actinia Hooker é uma espécie nativa de maracujazeiro, típica da Mata Atlântica e da Mata com Araucária, que apresenta valores econômico (fruto comestível), medicinal (atividades sedativa e ansiolítica), além de ser usada em propagação vegetativa (porta-enxerto para outras espécies de Passiflora). Este trabalho teve por objetivo

2. Dynamics of the restoration of physical trails in the grass-cutting ant Atta capiguara (Hymenoptera, Formicidae)
ABSTRACT Dynamics of the restoration of physical trails in the grass-cutting ant Atta capiguara. Leaf-cutting ants of the genus Atta build long physical trails by cutting the vegetation growing on the soil surface and removing the small objects they find across their path. Little is known on the dynamics of trail construction in these ants. How much time do

3. Fresamento com ar quente: uma proposta para minimizar a formação de trincas térmicas em ferramentas de metal duro
This work presents the results, analyses and conclusions about a study carried out with objective of minimizing the thermal cracks formation on cemented carbide inserts during face milling. The main focus of investigation was based on the observation that milling process is an interrupted machining process, which imposes cyclic thermal loads to the cutting t

4. Avaliação do processo de usinagem com corte interrompido utilizando a análise de esforços e frequências. / Interrupted cutting turning process evaluation using frequencies and forces analisys.
Processos de torneamento, muitas vezes na condição de corte interrompido, estão presentes em diversas operações na manufatura de componentes mecânicos, seja quando uma geometria específica é necessária como função deste componente ou quando ela é resultante de uma etapa anterior no processo produtivo, como no caso de peças forjadas. Este trabalh

5. The interrupted seduction : sexuality and power in Arab-Muslim narratives on female circumcision / A sedução interrompida : sexualidade e poder em poder em narrativas arabe-muçulmanas sobre a circuncisão feminina
This study of anthropological nature regards agressive practices imposed upon the feminine body in Muslim and Arab societies, namely genital cutting operations on women performed not for therapeutic reasons but to comform to an anatomical ideal compatible with specific cultural patterns. Conceptions like modesty, promiscuity and feminine sexuality shown in t

6. Sociocultural actiives, figurations, power and differentiation in Bico, Cuiamucu and Canela-Fina - amazon communities / Praticas socioculturais, poder e diferenciação em Bico, Cuiamucu e Canela-Fina - comunidades amazonicas
The study was made of three communities of the county of Boa Vista do Ramos, AM, 270 km from Manaus as the crow flies but 367 km by river. The trip from Manaus to Boa Vista takes 16 to 17 hours. From the city hall to Bicó, Cuiamucu and Canela-Fina it takes another two hours by motor canoe. Fictitious names for the communities studied were chosen to conceal

7. Some observations on wear and damages in cemented carbide tools
Cutting tools are subjected to extremely unfavorable conditions during machining operations. High cutting temperatures, compressive and shearing stresses, chemical attacks, variable cyclic thermal and mechanical loads are some adverse conditions that wear and damage these tools. Therefore, it is crucial to understand the process of tool wear and damage and h

8. Cerambicideos associados a melastomataceas : biologia e padrão de utilização das plantas hospedeiras, Serra do Japi, Jundiai-SP
Cerambycidae constitute one of the largest groups of insects, presenting cosmopolitan distribution, being very abundant and diversified in the tropics. Larvae of this beetle are wood borers, utilizing live or dead trunks. This study investigated aspects of the biology of Oncideres humeralis Thoms (Cerambycidae: Lamiinae), especificity cerambieid-host plant,

9. Estudo geológico e geofísico da falha de carnaubais, Bacia Potiguar-RN, e implicações neotectônicas
The segment of Carnaubais Fault located in the southeasthern portion of Guamaré Graben (Potiguar Basin) was studied. Several structures were detected and some of them strongly suggest that the last movements in Carnaubais Fault are of Neotectonic age. The study comprises an integrated interpretation of geologic, geomorphologic and geophysical data (gravimet

10. Site-Specific Recombination Determined by I-Scei, a Mitochondrial Group I Intron-Encoded Endonuclease Expressed in the Yeast Nucleus
The Saccharomyces cerevisiae mitochondrial endonuclease I-SceI creates a double-strand break as the initiating step in the gene conversional transfer of the omega(+) intron to omega(-) DNA. We have expressed a galactose-inducible synthetic I-SceI gene in the nucleus of yeast that also carries the I-SceI recognition site on a plasmid substrate. We find that t

11. Identification of the site of interruption in relaxed circles producing during bacteriophage lambda DNA circle replication.
The DNA that accumulates in the lambda infection restricted to the early (circular) stage of replication consists of approximately two-thirds covalently closed circles and one-third relaxed circles bearing a single interruption in either strand of the duplex. The latter molecules are presumed to be a unique class in that the interruption is not repairable by

12. restless, an active Ac-like transposon from the fungus Tolypocladium inflatum: structure, expression, and alternative RNA splicing.
Elements of the hAT transposon family, such as the maize activator (Ac), have been discovered in a large number of eukaryotic species. This type of class II transposon, present in both plants and animals, has not been previously detected in any fungal organism. However, using a differential screening method to detect repetitive DNA, we have identified a hAT
