1. Millet irrigation with treated wastewater: Gas exchange response and nutrient accumulation
RESUMO As águas residuárias podem ser consideradas como uma fonte hídrica e nutricional excelente para as plantas cultivadas. Porém, a presença de altas concentrações de sais e de compostos tóxicos pode afetar negativamente as plantações. Avaliou-se o efeito da irrigação com diferentes concentrações de água residuária tratada sobre o acumulo

2. IMPROVEMENT OF AN ANALYTICAL METHOD BASED ON HPLC WITH REFRACTIVE INDEX DETECTION FOR THE ANALYSIS OF GLYCEROL OXIDATION PRODUCTS
The optimized analytical methodology described herein is based on an ion exchange column and an H3PO4 solution (pH 2.24) as the mobile phase, with a flow rate of 0.4 mL min-1 and refractive index detection (RID). On applying the methodology, it was possible to identify 7 products obtained from the oxidation of glycerol with an analysis time of 27 min. The de

3. GROWTH AND PHOTOSYNTHETIC EFFICIENCY OF Atriplex nummularia UNDER DIFFERENT SOIL MOISTURE AND SALINE TAILINGS
RESUMO O descarte do rejeito dos dessanilizadores é um problema crescente sobretudo nas regiões semiáridas, sendo necessário o estudo de plantas halófitas como a Atriplex nummularia para o reuso dessas águas salinas. Dessa forma, objetivou-se avaliar o efeito da interação entre níveis de teor de água solo e de salinidade da água de irrigação, na

5. Não linearidade entre câmbio e preços no Brasil e implicações para uma estratégia de desenvolvimento econômico
RESUMO O objetivo deste artigo é realizar uma análise da política monetária no Brasil a partir de um modelo de Vetores Autorregressivos com Cadeias de Markov (MS-VAR), na busca de evidências da não linearidade da relação entre câmbio e preços no Brasil. A análise demonstrou que, em períodos de apreciação cambial, tanto pelo lado da demanda quan

6. Water deficit modifies the carbon isotopic composition of lipids, soluble sugars and leaves of Copaifera langsdorffii Desf. (Fabaceae)
ABSTRACT Water deficit is most frequent in forest physiognomies subjected to climate change. As a consequence, several tree species alter tissue water potential, gas exchange and production of carbon compounds to overcome damage caused by water deficiency. The working hypothesis, that a reduction in gas exchange by plants experiencing water deficit will affe

7. Soil Fertility and Electrical Conductivity Affected by Organic Waste Rates and Nutrient Inputs
ABSTRACT The composition of organic waste (OW) and its effect on soil processes may change soil fertility and electrical conductivity (EC). The side effects of waste use in crop fertilization are poorly understood for Brazilian soils. This study examined the effect of the addition of 15 different organic wastes to Oxisols and a Neosol on pH, base saturation,

8. Photosynthetic gas exchange and antioxidative system in common bean plants infected by Colletotrichum lindemuthianum and supplied with silicon
This study investigated the effects of silicon (Si) on the resistance of common bean plants to anthracnose caused by Colletotrichum lindemuthianum. The plants were grown in a nutrient solution containing 0 (control) or 2 mM Si (+Si) and both photosynthesis and antioxidative metabolism levels were evaluated. The Si concentrations in the leaf tissues of +Si pl

9. Therapeutic effects of blood purification in treatment of fulminant hepatic failure
OBJECTIVES: To evaluate the clinical effects of blood purification for treating fulminant hepatic failure (FHF). METHODS: Thirty-three severe FHF patients with hepatic encephalopathy (HE) above grade III were subjected to a combined blood purification treatment in addition to the comprehensive liver protection therapy. Patients underwent continuous hemofiltr

10. Resposta do arroz de terras altas a diferentes doses de carvão vegetal: desenvolvimento da planta e deficiência hídrica / Resposta do arroz de terras altas a diferentes doses de carvão vegetal: desenvolvimento da planta e deficiência hídrica / Response of upland rice to different doses of charcoal, plant development and water deficit / Response of upland rice to different doses of charcoal, plant development and water deficit
The average national rice yield was 11,3 million tones, with a harvested area of about 2,7 million hectares (IBGE 2010). Part of this comes from upland production systems in savannas that have high acidity, low fertility, with low phosphorus and potassium levels, low cation exchange capacity and high aluminum saturation. Upland rice in the Brazilian savannas

11. Gas exchange in massai grass under five nitrogen fertilization levels during establishment and regrowth
The objective of this study was to evaluate gas exchange in the massai grass during establishment and regrowth cycles in a greenhouse, using five nitrogen (N) fertilization levels. A completely randomized split-plot design of five nitrogen levels (0; 150; 300; 450 and 600 mg N•dm-3 of soil) was employed with the N levels as plots, and the cycles (establish

12. Equilibrium study of binaries and ternary ion exchange systems envolving copper, cadmium and calcium ions by alginate biopolymer / Estudo do equilibrio dos sistemas binarios e ternario de troca ionica dos ions cobre, cadmio e calcio pelo biopolimero alginato
In this work, it was studied the ion exchange process involving copper, cadmium and calcium ions. The heavy metals, copper and cadmium, were evaluated due to its high toxicity, its presence in industrial effluent and difficulty in its removal when in low concentrations, however, above permitted levels by law. Alginate was used as ionic exchanger. In the pres
