1. Aspectos da biogeoquímica dos rios Teles Pires e Cristalino - MT / Aspects of the biogeochemistry of Teles Pires and Cristalino rivers - MT
The Amazon basin occupies around 40% of the brazilian territory and contains more than 60% of the water resources of the country. Abundant and yet little exploited region water resources constitute a national treasure to which the nation can not turn its back. Besides changes in land use/cover, several hydroelectrical plants are planned for rivers in the reg

2. Accumulation of organic and inorganic solutes in NaCl-stressed sorghum seedlings from aged and primed seeds
Although it has been known that the seed's physiological potential affects its response to osmoconditioning and abiotic stresses, researches involving seed aging and priming associated to abiotic stresses are scarce. The aim of this work was to evaluate the role of seed priming on salt tolerance in sorghum seedlings from seeds with two vigor levels (aged or

3. Physiological answers and biochemists in meloeiro (Cucumis melo L) inoculated with arbuscular mycorrhizal fungi (AMF) under estresse saline / Respostas fisiolÃgicas e bioquÃmicas em Meloeiro (Cucumis melo L.) inoculado com fungos micorrÃzicos arbusculares sob estresse salino
Nas regiÃes Ãridas e semi-Ãridas à comum a acumulaÃÃo de sais no solo em quantidades prejudiciais ao crescimento e rendimento das plantas. Neste contexto, os fungos micorrÃzicos arbusculares (FMA) vÃm sendo estudados nos Ãltimos anos, havendo resultados que indicam que as associaÃÃes micorrÃzicas com as plantas minimizam alguns efeitos do estress

4. AlteraÃÃoes fisiolÃgicas e bioquÃmicas em plÃntulas de cajueiro anÃo-precoce submetidas à salinidade em duas condiÃÃes de cultivo / Physiological and biochemical changes in early-dwarf cashew seedlings subjected to salinity in two cultivation conditions
O presente trabalho teve por objetivo estudar as respostas fisiolÃgicas e bioquÃmicas de plÃntulas de cajueiro anÃo-precoce (Anacardium occidentale L.) Ã salinidade em duas condiÃÃes ambientais de cultivo. Para isso, as plÃntulas foram cultivadas em vasos de polietileno contendo somente soluÃÃo nutritiva (tratamento controle) ou soluÃÃo nutritiva

5. Estudo da cristalização de lactose em diferentes solventes
In the study of the lactose crystallization process, the nucleation phenomena and crystalline growth have been evaluated, when the systems were submitted to different solvent and operational conditions. The solubilitys curves, for each of the solvents, were obtained experimentally and compared with theoretical data, serving as a basis for the crystallization

6. ESTUDO EXPERIMENTAL DA INTERAÇÃO FOLHELHO-FLUIDO ATRAVÉS DE ENSAIOS DE IMERSÃO / EXPERIMENTAL STUDY OF INTERACTION SHALE-FLUID THROUGH IMMERSION TESTS
Most of borehole instability problems occur when argillaceous rocks such as shales are drilled and the drilling fluid interacts with the rock. The rock-fluid interaction is materialized through the exchange of ions and water molecules between the drilling fluid and the rock, generating pore pressure variation inside the shale and changes in minerals structur

7. Nonradioactive monitoring of organic and inorganic solute transport into single Xenopus oocytes by capillary zone electrophoresis.
Transport of organic and inorganic solutes into and out of cells requires specialized transport proteins. Given a sufficiently sensitive analytical method for measuring cellular solute concentrations, it should be possible to monitor solute transport across the plasma membrane at the level of single cells. We report a capillary zone electrophoresis approach

8. Growth, Water Relations, and Accumulation of Organic and Inorganic Solutes in Roots of Maize Seedlings during Salt Stress.
Seedlings of maize (Zea mays L. cv Pioneer 3906), hydroponically grown in the dark, were exposed to NaCl either gradually (salt acclimation) or in one step (salt shock). In the salt-acclimation treatment, root extension was indistinguishable from that of unsalinized controls for at least 6 d at concentrations up to 100 mM NaCl. By contrast, salt shock rapidl

9. Hormone-Solute Interactions in the Lettuce Hypocotyl Hook 12
The hypocotyl hook of the lettuce (Lactuca sativa cv. Grand Rapids) seedling is stimulated to a high degree of curvature through a synergistic interaction of ethylene and gibberellic acid in the light. Presentation of various inorganic salts to the seedlings caused extensive alteration of the hormone-induced curvatures, with ammonium and sulfate being the mo

10. Major Facilitator Superfamily
The major facilitator superfamily (MFS) is one of the two largest families of membrane transporters found on Earth. It is present ubiquitously in bacteria, archaea, and eukarya and includes members that can function by solute uniport, solute/cation symport, solute/cation antiport and/or solute/solute antiport with inwardly and/or outwardly directed polarity.

11. Osmotic significance of glycerol accumulation in exponentially growing yeasts.
Natural-abundance 13C-nuclear magnetic resonance spectroscopy has shown glycerol to be the major osmotically significant low-molecular-weight solute in exponentially growing, salt-stressed cells of the yeasts Saccharomyces cerevisiae, Zygosaccharomyces rouxii, and Debaromyces hansenii. Measurement of the intracellular nonosmotic volume (i.e., the fraction of

12. The Relationship between Inorganic Nitrogen Metabolism and Proline Accumulation in Osmoregulatory Responses of Two Euryhaline Microalgae 1
Chlorella autotrophica, a euryhaline marine alga, and Stichococcus bacillaris, a salt-tolerant soil alga, grow in the presence of methionine sulfoximine (MSX), an inhibitor of glutamine synthetase, by maintaining high levels of NADPH-glutamate dehydrogenase. Nitrate reductase showed no change in MSX-adapted cells. For both species, MSX-adapted cells retained
