1. In vitro induction and regeneration of tetraploids and mixoploids of two cassava cultivars
Abstract We report the in vitro induction of polyploids from two cassava cultivars by colchicine treatment. Shoot nodal segments, collected from in vitro cultivated plants of Porquinho and Vassourinha cultivars, were used as explants. Explants were treated in liquid media without and with colchicine (0.05, 0.10 or 0.15%), at 90 rpm, in the dark, for 48 or 96

2. 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

3. Anatomia de folhas e raízes de Aechmea lindenii (E. Morren) Baker var. lindenii (bromeliaceae)
Aechmea lindenii (E. Morren) Baker var. lindenii (Bromeliaceae-Bromelioideae) ocorre em restingas e Floresta Pluvial de Encosta Atlântica em Santa Catarina e Nordeste do Rio Grande do Sul, BR. Pode ser encontrada total ou parcialmente exposta à irradiação solar e em distintas formas de vida - terrícola, rupícola e epifítica. Apresenta variações morf

4. Padrão de venação e epiderme foliar de espécies de lauraceae juss do Distrito Federal, Brasil
Eighteen Lauraceae species, occurrent in Distrito Federal Brazil, had their leaf blades examined with the aim to assess the general characters usually considered in studies about epidermis and leaf architecture beyond proposing the use of additional characters. For the venation patterns analysis, some characters were proposed as well as the distancing betwee

5. ObtenÃÃo e CaracterizaÃÃo de calos e plÃntulas a partir de embriÃes zigÃticos imaturos de Coffea arabica L. e anÃlise in silico do Gene Serk / Obtaining and characterization of calluses and plantules starting from immature zygotic embryos of Coffea arabica L. and gene SERK in silico analysis
It was intended in this work be obtained alternatives to the explant to foliate and nodal seeking the micropropagation of you cultivate of coffee plants related to the quality of the drink, like âBourbon Amareloâ and to the productivity as the âRubiâ for the south area of Minas Gerais. A main plant of Bourbon Amarelo was used for obtaining of the fruits

6. Reavaliação do papel do óxido nítrico como um componente da rota de sinalização do ácido abscísico em células-guardas / Re-evaluation of the role of nitric oxide as a component of abscisic acid signalling pathway in guard cells
O ácido abscísico (AAB), sintetizado em resposta ao défice hídrico, induz o fechamento dos estômatos via ativação de uma complexa cascata de sinalização. Tem-se demonstrado que o óxido nítrico (ON) é um componente chave na cadeia de sinalização que leva ao fechamento dos estômatos induzido pelo AAB em várias espécies, sob boa disponibilidade

7. Morfo-anatomia e fitoquímica de Cymbopogon densiflorus (Steud.) Stapf e Cymbopogon nardus (L.) Rendle (Poaceae: Panicoideae) / Morphology, anatomy and phytochemistry of Cymbopogon densiflorus (Steud.) Stapf and Cymbopogon nardus (L.) Rendle
The genus Cymbopogon Sprengel belong to the Poaceae family and it has 40 species distributed in Tropical and Subtropical Africa, Asia and Australia, although some species went introduced in America. Many species of this genus are cultivated for the extraction of essential oil, from their leaves, with large medicinal, food and industrial importance. The speci

8. Efeito da suplementação calórico-protéica no sistema imunológico de homens integrantes do grupamento ciclístico da guarda civil municipal de Piracicaba - SP / Effect of the energetic-proteic supplementation in the immune system of members of the bykers group belonging to the Civil Municipal Guard Piracicaba - SP
O objetivo deste trabalho foi verificar os efeitos da suplementação energético-protéica na contagem de células T e de seus subtipos CD4 e CD8. Os sujeitos eram praticantes de atividade física de carga alta e diária. Foram avaliados em dois momentos: repouso (antes da atividade) e agudo (após a atividade). A contagem de células foi feita por citômet

10. cellular networks; Mobile networks / Controle de admissÃo de chamas e reserva de recursos em redes mÃveis celulares
Handoff in wireless/mobile networks is the mechanism that transfers an ongoing call from the current cell as the mobile station moves through the coverage area of the system. User applications may experience performance degradation due to handoffs from user mobility. If the target cell does not have sufficient available bandwidth, the call will be dropped. F

11. Aspectos da biologia, estrutura populacional e parentesco intranidal em vespas do gênero Trypoxylon (Hymenoptera: Sphecidae).
Wasps of the genus Trypoxylon (Sphecidae) building their nests with mud and mass-provisioned them with paralyzed spiders. The males of the subgenus Trypargilum may act as guards during the period of nest construction and provisioning. This behavior is common to other Sphecidae, but unusual in Hymenoptera. Theoretically, such behavior makes sense, due to hapl

12. Evidence for an Extracellular Reception Site for Abscisic Acid in Commelina Guard Cells.
The phytohormone abscisic acid (ABA) triggers stomatal closing as a physiological response to drought stress. Several basic questions limit an understanding of the mechanism of ABA reception in guard cells. Whether primary ABA receptors are located on the extracellular side of the plasma membrane, within the intracellular space of guard cells, or both remain
