1. Biologia de nidificação e estrutura sociogenética de ninhos de Trypoxylon (Trypargilum) albitarse Fabricius 1804 (Hymenoptera: Crabronidae): comportamento de guarda do macho e paternidade
Crabronid wasps of the genus Trypoxylon are characterized by being solitary and nest in preexisting cavities or in mud nests. The species Trypoxylon (Trypargilum) albitarse is included in the latter group, because builds its own mud nests. These nests are made by mud tubes with the lower portion open. Each tube is internally formed by a linear series of cell

2. CATENARY DOME OF FIBER SOIL STRUCTURED WITH BAMBOO - CONCEPTION AND CONSTRUCTIVE PROCESS / CÚPULA CATENÁRIA DE FIBROBARRO ESTRUTURADO COM BAMBU - CONCEPÇÃO E PROCESSO CONSTRUTIVO
The current model of cities development, considering the wild consumption of not renewable resources, has shown impracticable due the sustainability point of view. Fact which is really concerned a lot of preoccupation in many sectors of human society. In the world-wide scenery, mainly at civil construction sector, it is growing a big demand for the use of ne

3. The agroecological transition in rice-fish growing : the case from 25 of november settlement, Capão do Leão, RS. / A transição agroecológica em rizipiscicultura : o caso do assentamento 25 de novembro, Capão do Leão, RS.
Rice-fish growing, based on agroecology, combines the cultivation of irrigated rice and the growing of fish, in the absence of pesticides. Two situations occur: the simultaneous in which rice and fish are grown together and the alternate, which intercalates fish and rice. In a participative work, a reference experiment was installed for the agroecological tr

4. Pyrethroid insecticide evaluation on different house structures in a Chagas disease endemic area of the Paraguayan Chaco
Insecticide effects of deltamethrin 2.5% SC (flowable solution) on different substrates and triatomine infestation rates in two indigenous villages (Estancia Salzar and Nueva Promesa) of the Paraguayan Chaco are reported. This field study was carried out to determine the extent to which variability in spray penetration may affect residual action of the insec

5. CONSTRUÇÃO COM FIBROSOLO: UM ESTUDO DE CASO SOBRE O RESGATE DA TÉCNICA DE TAIPA, E SEUS EFEITOS NO AMBIENTE DE CLIMA TROPICAL ÚMIDO COM ESTAÇÃO SECA E CHUVAS DE VERÃO / FIBER SOIL CONSTRUCTION: A CASE STUDY CONCERNING THE RECOVERY OF MUD WALL TECHNIQUES AND THEIR EFFECTS ON HUMID TROPICAL CLIMATE ENVIRONMENTS
Our goal is the search for development models that minimize environment impact. The benefits deriving from mans constructed objects on these environments reflect an adequate interference to the inhabited space. The resulting interference from habitation constructions is described. A process of deterioration and impoverishment of traditional constructive know

6. Genetic Control of Male Germ Unit Organization in Arabidopsis1
In flowering plants, the vegetative nucleus and the two sperm cells are proposed to form a functional assemblage, the male germ unit (MGU). Here, we describe the developmental pathway of MGU assembly in Arabidopsis and report two classes of mutations that affect the integrity and/or the positioning of the MGU in the mature pollen grain. In germ unit malforme

7. Titanospirillum velox: A huge, speedy, sulfur-storing spirillum from Ebro Delta microbial mats
A long (20–30 μm), wide (3–5 μm) microbial-mat bacterium from the Ebro Delta (Tarragona, Spain) was grown in mixed culture and videographed live. Intracellular elemental sulfur globules and unique cell termini were observed in scanning-electron-microprobe and transmission-electron micrographs. A polar organelle underlies bundles of greater than 60 flag

8. Defining a rob Regulon in Escherichia coli by Using Transposon Mutagenesis
The Rob protein of Escherichia coli is a member of the AraC-XylS family of prokaryotic transcriptional regulators and is expressed constitutively. Deletion of the rob gene increases susceptibility to organic solvents, while overexpression of Rob increases tolerance to organic solvents and resistance to a variety of antibiotics and to the superoxide-generatin
