1. Anatomical and histochemical studies of the somatic embryogenesis of Syagrus oleracea from immature inflorescences
Abstract Anatomical and histochemical studies were carried out during the somatic embryogenesis of Syagrus oleracea (Mart.) Becc. from immature inflorescences. Immature rachillas were inoculated on Murashige and Skoog medium with 4.52 μM 4-amino-3,5,6-trichloropicolinic acid (Picloram) and 2,4-diclorophenoxyacetic acid. Auxin concentrations were gradually r

2. Gonadal development and reproductive period of the characin Astyanax aff. bimaculatus (Characiformes: Characidae) in a tropical reservoir in southeastern Brazil
ABSTRACT The gonadal development of the characin Astyanax aff. bimaculatus from Funil Reservoir, an impoundment in the middle reaches of the Paraiba do Sul River in southeastern Brazil was analysed through histological, histochemical and histometric techniques, and the spawning season was determined. Unbalanced sex ratio was found, with females outnumbering

4. NEAR INFRARED SPECTROSCOPY: RAPID AND ACCURATE ANALYTICAL TOOL FOR PREDICTION OF NON-STRUCTURAL CARBOHYDRATES IN WOOD
ABSTRACT The non-structural carbon reserves in the various organs of trees are associated with their growth and the mechanism of resilience when exposed to environmental stresses, especially the water deficit. The goal of this study was to develop multivariate models to estimate the amount of non-structural carbohydrates (starch, sucrose, reducing sugars, to

5. Efectos del uso de electrolitos soportes en ensayos electroquímicos de la aleación Al-4%Mg expuesta a bioetanol combustible
ABSTRACT The growth of world energy demand directly affects the consumption of petroleum-based fuels, increasing the negative impact of the use of these fuels and the decrease of crude oil reserves. This creates an opportunity for the use of fuels that are more efficient, of low environmental impact and, above all, of a renewable nature. Bioethanol is a biof

6. The effect of Agaricus brasiliensis extract supplementation on honey bee colonies
ABSTRACT This study was done to discover any beneficial effect of a medicinal mushroom Agaricus brasiliensis extract on the honey bee. Firstly, a laboratory experiment was conducted on 640 bees reared in 32 single-use plastic rearing cups. A. brasiliensis extract proved safe in all doses tested (50, 100 and 150 mg/kg/day) irrespective of feeding mode (sugar

7. Survival and growth of tree seedlings as a function of seed size in a gallery forest under restoration
ABSTRACT Seed size is commonly related to higher rates of emergence and survival, and biomass of seedlings when introduced by direct seeding. However, few studies have evaluated whether this relationship persists when species are reintroduced as seedlings or if this effect persists after seed reserves decline. This study evaluated the effect of seed size (ma

8. Protein content of leaf-cutting ant queens before the nuptial flight and during the post-claustral phase
Protein content of leaf-cutting ant queens before the nuptial flight and during the post-claustral phase. This study evaluated the crude protein content of queens of Atta sexdens before the nuptial flight and after the claustral phase in laboratory and field colonies. The hypothesis was that protein is used for survival of the queen and for early colony grow

9. Optimization of biodegradable plastic production on sugar cane molasses in Enterobacter sp. SEL2
Contaminated environments have a large number of bacteria which can accumulate PHA as their energy reserves. Out of 54 isolated bacterial strains from three groups of contaminated sites 48 were found PHA positive. The sites were grouped on the basis of the type of carbon sources i.e. sugars, fatty acids and much diverse type. Strains MFD5, MFD11, UML3, USL2,

10. Effects of both ecdysone and the acclimation to low temperature, on growth and metabolic rate of juvenile freshwater crayfish Cherax quadricarinatus (Decapoda, Parastacidae)
Growth, metabolic rate, and energy reserves of Cherax quadricarinatus (von Martens, 1868) juveniles were evaluated in crayfish acclimated for 16 weeks to either 25ºC (temperature near optimum) or 20ºC (marginal for the species). Additionally, the modulating effect of ecdsyone on acclimation was studied. After 12 weeks of exposure, weight gain of both exper

11. OPPORTUNITIES CREATED BY GLOBAL ALLIANCES IN THE OIL &GAS INDUSTRY FROM THE PERSPECTIVE OF NETWORK THEORY: THE CASE OF TECHNIP BRASIL / OPORTUNIDADES CRIADAS PELAS ALIANÇAS GLOBAIS NA INDÚSTRIA DE ÓLEO E GÁS NA PERSPECTIVA DA TEORIA DE REDE: O CASO DA TECHNIP BRASIL
This research was motivated by the perception of momentum that the oil and gas industry is going through in Brazil, with the discovery of new oil reserves, and consequent economic growth of the country. Thus, from these new discoveries, several opportunities begin to arise for companies operating in this industry. However, due to the high complexity and inve

12. Alternativas técnico produtivas para o aproveitamento do gás natural da camada pré-sal / Technical productive alternatives to the use of natural gas in pre-salt layer
The Brazilian reserves of oil and natural gas will present a significant growth from the development of the reserves of the pre-salt layer. According to estimates prepared by the EPE and the EIA, the next twenty years, the supply of natural gas will exceed demand. As the transportation sector natural gas has great importance in the formation of the cost of e
