1. Differential leaf gas exchange performance of mango cultivars infected by different isolates of Ceratocystis fimbriata
ABSTRACT Caused by the vascular fungus Ceratocystis fimbriata, mango wilt is considered to be one of the most serious threats in mango-producing regions worldwide. However, changes in leaf gas exchange level and the mechanisms underlying host responses to this fungal infection remain poorly described. This study aimed to evaluate potential changes in the lea

2. Análise de simulantes para produtos ácidos acondicionados em embalagens metálicas / Analysis of simulants to acidic products conditioned in meal package
Tin-plate cans represent most of the cans for canned food. Since they are not inert, during the storage period, interaction occurs with the product and metal dissolution can occur, especially when it is acid food. To minimize this interaction it is used organic coatings, and epoxy-phenolic resin is the the most used. As the foods are complex biochemical syst

3. Comportamento fisiologico de duas cultivares de amendoim submetidas a diferentes regimes hidricos.
Duas cultivares de amendoim (Arachis hypogaea L.) foram submetidas a 10 dias de suspensao de rega em casa de vegetacao, objetivando compara-la quanto ao carater resistencia a seca. As cultivares Nigeria 55437 (CNPA 76 AM), resistente, e IAC Tupa, sensivel, foram semeadas em potes, recebendo suprimento hidrico normal ate 20 dias apos a semeadura, quando houve

4. Numerical Simulation of Accidental Explosions in Offshore Production Plant
The production of oil and gas is an inherently hazardous task. Therefore it is crucial to provide reliable estimates of the risks involved. The major contributors to the risk level of an offshore installation, for example, arise from accidents involving explosion and fire. Computational Fluid Dynamics (CFD) can be a powerful tool to help with the calculation

5. Avaliação fisiológica da aroeira (Schinus terebinthifolius Raddi) sob déficit hídrico com vista para o reflorestamento.
This work aimed to study the effect of water deficit on gas exchange, leaf water potential, dry matter production, and some biochemical aspects of Schinus terebinthifolius Raddi. young plants. A research project was developed, under greenhouse conditions, at the Laboratório de Fisiologia Vegetal, Departamento of Biologia of Universidade Rural de Pernambuco

6. Nitrogen fertilization effects and phosphorus sources in sabiá (Mimosa caesalpiniaefolia Benth.), subjected to hydric stress. / Efeitos da adubação nitrogenada e fontes de fósforo em sabiá (Mimosa caesalpiniaefolia Benth.), submetido ao estresse hídrico.
Due to the social accountability demanded from university research, this study is related to the challenge of making available development strategies for regionssuch as the semi-arid northeastern regions, which is characterized mainly by its limited soil and climate conditions. The purpose of this work was to assess the behavior of sabiá seedlings (Mimosa c

7. Aspectos do comportamento de gás metano dissolvido na água de reservatórios brasileiros / Aspects of dissolved methane behavior in water bodies of brazilian reservoirs
Extended water bodies such as the hydroelectric reservoirs here studied can be greenhouse gas sources ( CH IND.4 and CO IND.2 ) due to decay of part of submerged forest biomass and also due to allochtonous and autochtonous organic compounds. This work presents concentrations, ebullitive and diffusive fluxes of the gases dissolved in the water column in the f

8. Superficial Nitrogen Enrichment of Austenitic stainless steel ISO 5832-1 / ElevaÃÃo do teor superficial de nitrogÃnio no aÃo inoxidÃvel austenÃtico ISO 5832-1
The insertion of nitrogen in stainless steel has been studied since 1925. When in solid solution it produces a few effects such as: increase in mechanical strength, hardness, resistance to fatigue, to wear and corrosion. Although benefic effects of nitrogen on the proprieties of steel are well known, the introduction of this element in high amounts is not tr

9. Caracteristicas morfo-fisiologicas dofeijoeiro (Phaseolus vulgaris L.) relaci onadas com a resistencia a seca
The study was conducted at the National Pice and Bean Research Center (CNPAF-EMBRAPA) experimental station Goianira GO during the months of May to August in the year 1987 and 1988. The objectives of the experiments conducted were to evaluate drought resistance mechanisms in bean cultivar BAT 477 Carioca; and RAB 96 all promising for planting during dry perio

11. Stomatal Dimensions and Resistance to Diffusion 1
In the past, relations of diffusive resistance to stomatal geometry have concerned circular pores or pores that are replaced by equivalent circles of the same area. We calculated the resistance for general shapes that include the realistic slit. The resistance comprises two terms. The first is an outer resistance that depends only on ventilation and leaf geo

12. Effect of Leaf Water Deficit on Stomatal and Nonstomatal Regulation of Net Carbon Dioxide Assimilation 1
The effect of leaf water deficit on net CO2 assimilation was studied under two conditions: in one, the stomata were allowed to contribute to the regulation of CO2 assimilation; in the other, air was forced through the leaf at a constant rate to overcome the effects of change in stomatal resistance accompanying changes in leaf water deficit. When the stomata
