2. Anatomy, histochemistry and oxalic acid content of the leaflets of Averrhoa bilimbi and Averrhoa carambola
Abstract Averrhoa bilimbi L. and A. carambola L., Oxalidaceae, are the only two species of the genus Averrhoa L. Their leaves are widely used in folk medicine as an adjuvant in the treatment of diabetes. Some species may contain, for example, calcium oxalate crystals, which may lead to risk in its use when there is predisposition of individuals with reduced

3. Effect of growth regulators application on the quality maintenance of 'Brookfield' apples
AbstractThe main goal of the present study was to elucidate the effect of growth regulators at harvest and postharvest quality of 'Brookfield' apples stored under controlled atmosphere through a multivariate approach. Thus, an experiment with two steps (field and storage) was carried out. The treatments in field were applied with an output of 1,000 L ha–1

4. Avaliação da formação de trialometanos considerando o uso de cloro e permanganato de potássio como pré-oxidantes em águas de abastecimento / Evaluation of Formation of Trihalomethanes considering the Use of Chlorine and potassium permanganate as pre-oxidants in drinking water supplies
O cloro tem sido utilizado como principal pré-oxidante da matéria orgânica, inativando microrganismos patogênicos que vivem em águas naturais há mais de cem anos. A matéria orgânica encontrada em mananciais superficiais contém substâncias húmicas que podem reagir com o cloro, gerando compostos orgânicos halogenados potencialmente cancerígenos, d

5. Ação de absorvedores de etileno e de oxigênio na conservação pós-colheita de morango / Action of ethylene and oxygen absorbers on postharvest strawberry conservation
The present work aimed to study the influence of the PVC (polyvinyl chloride) film of different concentrations of KMnO4 (ethylene absorbent) and the oxygen absorber sachet (O-Buster) on the quality and postharvest conservation of Oso Grande strawberries. In order to achieve this physical-chemical, enzymatic and visual analyses were performed every 2 days on

6. Determination of cinnamic acid in human urine by flow injection chemiluminescence
It was found that cinnamic acid can react with potassium permanganate in the acidic medium and produce chemiluminescence, which was greatly enhanced by glyoxal. Under the optimum conditions, the linear range for the determination of cinnamic acid was 1.0×10-8 to 1.0×10-4 mol L-1 with a detection limit of 8.0×10-9 mol L-1, the relative standard deviation w

7. Avaliação do processo oxidativo avançado por permanganato de potássio no tratamento de solos contaminados com idrocarbonetos poliaromáticos / Evaluation advanced oxidation Process by permanganate potassium in the Treatment of contaminated Soils with Polyaromatic Hydrocarbons
A contaminação de solo com petróleo é uma das grandes preocupações das indústrias que atuam no ramo e também dos órgãos ambientais. O petróleo é constituído basicamente por hidrocarbonetos alcanos e aromáticos. Os exemplos mais comuns dos hidrocarbonetos poliaromáticos são: naftaleno, antraceno, fenantreno, benzopireno e seus vários isômero

8. Embalagens ativas de fonte renovável / Active packaging from renewable source
Active biodegradable packaging foams type were developed, obtained from cassava starch, to increase the shelf-life of minimally processed fruits. For this, active agents that prevent the proliferation of fungi, weight loss and, still, provide a visual indication (change of packaging color) of the packaged product quality, were added to the renewable packagin

9. Remoção de sulfeto de hidrogênio, ferro e manganês de águas de abastecimento através dos processos de dessorção gasosa, nanofiltração e oxidação com permanganato de potássio
Many regions in Brazil have problems associated with the water quality of their supplies, which bring problems to the production of safe drinking water that is distributed in communities. Generally, consumers judge the drinking water safety through the use of their organoleptic senses. The conventional processes used in water treatment are not effective to r

10. Conservação refrigerada de lima ácida "Tahiti" em combinação com atmosfera modificada, ácido giberélico e permanganato de potássio / Cold storage Tahiti lime in combination with modified atmosphere, gibberellic acid and potassium permanganate
Although Brazil is the largest producer and exporter of Tahitilime, actually, exports only 5% of total production. This is, in part, because of a lack of quality of these limes, characterized by loss of green skin colour after harvest. The purpose of this research was to evaluate the efficiency of modified atmosphere, gibberellic acid (GA) and potassium perm

11. Removal of microcystins in water from eutrophic reservoir involving technical of clarification, pre-oxidation with potassium permanangate, adsorption with powdered activated carbon and post-chlorination / Remoção de microcistina em águas provenientes de reservatório eutrofizado associando técnicas de clarificação, pré-oxidação com permanganato de potássio, adsorção em carvão ativado e pós-cloração
The present work had as objective to evaluate the removal of three different concentrations of extracellular microcystins in different combinations of water treatment for supplying, in bench scale, that had as basic sequence the clarification associated or not with the processes of pre-oxidation with KMNO IND.4, adsorption on PAC and post-chlorination.

12. Conservação pós-colheita do jiló em embalagens ativas / The post-harvest conservation of the giló Solanum gilo Raddi in active packages
The Solanum gilo Raddi (jiloeiro) belongs to the Solanaceae family. The immature fruits are light-green or dark-green colored, but become orangereddish when ripe. The flavor of the fruits in all cultivars are characteristically bitter, which is agreeable to some consumers, but limits their consumption by others . The giló S. gilo is considered a vegetable t
