Produtividade E Qualidade De Cultivares De Batata Para Industrialização Na Forma De Batata-palha E Chips

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Brazilian market of potato processing has presented expressive development in recent years. However,its expansion is constrained by raw material supply suitable for industrial processing. Selection of adequate cultivars contributes to final product cost reduction as well as its yield and quality improvement. The research aimed to study tuber yield and evaluate its frying potential for shoestrings and chips,of potato cultivars recently introduced in Brazil. Nine potato cultivars (Arizona,Caruso,Destiny,Excelence,Saviola,Agata,Almera,Fontane and Markies) were assessed in an experiment carried out between January and May,2013,in South-West region of Minas Gerais State,Brazil. ‘Arizona’ and ‘Caruso’ cultivars exhibited superior productive potential and along with ‘Markies’ the highest production of marketable tubers. ‘Caruso’ and ‘Destiny’ produced more than 20% of dry matter and the lowest reducing sugar levels. ‘Caruso’ exhibited the highest frying yield in both processing shapes and absorbed less fat as shoestring. ‘Destiny’ absorbed less fat when processed as chips. ‘Excelence’ presented intermediary performance for every evaluated attribute. ‘Caruso’,‘Destiny’,and ‘Excelence’ produced chips with appropriate color for market. Among the assessed cultivars,‘Caruso’,‘Destiny’,and ‘Excelence’ were the most promising. These cultivars demonstrated appropriate processing ability in the shape of shoestrings. ‘Destiny’ could also be indicated to be processed as chips. © 2016,Sociedade de Olericultura do Brasil.

A method for finding new sets of axioms for classes of semigroups

We introduce a general technique for finding sets of axioms for a given class of semigroups. To illustrate the technique, we provide new sets of defining axioms for groups of exponent n, bands, and semilattices

DEBATENDO O FAZER DIDÁTICO: A PERCEPÇÃO DOS ESTUDANTES DE CIÊNCIAS CONTÁBEIS ACERCA DAS ESTRATÉGIAS DIDÁTICAS UTILIZADAS

O presente estudo buscou analisar a percepção dos estudantes sobre as estratégias didáticas utilizadas pelos seus professores. O estudo de natureza descritiva, do tipo survey e com abordagem quali-quantitativa analisou dados de 131 estudantes de Ciências Contábeis do 1º ao 8º período da maior universidade privada do país. As técnicas de análise de dados utilizadas foram a estatística descritiva à luz das teorias pedagógicas vigentes. Os resultados demonstraram que em geral os professores utilizam estratégias ativas e passivas (ambas) e que os alunos percebem essa combinação (58%) como mais proveitosa para o processo de ensino-aprendizagem. Dentre as contribuições das estratégias didáticas para o processo de ensino-aprendizagem destacaram-se: Resolução de exercícios (16%); Aula expositiva (15%); Discussão e debates (13%); Estudo de Caso (12%). Além disso, na perspectiva dos respondentes existe uma necessidade de maior comprometimento das partes (35,64%) e conexão com o mercado de trabalho (40,28%) para que o processo de ensino-aprendizagem melhore. 

SALO, a novel classical pathway complement inhibitor from saliva of the sand fly Lutzomyia longipalpis.

Blood-feeding insects inject potent salivary components including complement inhibitors into their host's skin to acquire a blood meal. Sand fly saliva was shown to inhibit the classical pathway of complement; however, the molecular identity of the inhibitor remains unknown. Here, we identified SALO as the classical pathway complement inhibitor. SALO, an 11 kDa protein, has no homology to proteins of any other organism apart from New World sand flies. rSALO anti-complement activity has the same chromatographic properties as the Lu. longipalpis salivary gland homogenate (SGH)counterparts and anti-rSALO antibodies blocked the classical pathway complement activity of rSALO and SGH. Both rSALO and SGH inhibited C4b deposition and cleavage of C4. rSALO, however, did not inhibit the protease activity of C1s nor the enzymatic activity of factor Xa, uPA, thrombin, kallikrein, trypsin and plasmin. Importantly, rSALO did not inhibit the alternative or the lectin pathway of complement. In conclusion our data shows that SALO is a specific classical pathway complement inhibitor present in the saliva of Lu. longipalpis. Importantly, due to its small size and specificity, SALO may offer a therapeutic alternative for complement classical pathway-mediated pathogenic effects in human diseases

Phosphate fertilization and phosphorus forms in an Oxisol under no-till

Under no-till phosphorus (P) accumulates in a few centimeters of the topsoil layer. Plant residues left on the soil surface release P and organic acids, which may improve P availability and fertilizer efficiency, including both soluble (such as triple super phosphate) and less soluble sources (such as reactive natural phosphates). In this study, soybean response to P fertilizer and P forms in the top 40 cm of an Oxisol were evaluated after surface application of different phosphates in a 5-year-old no-till system. Treatments consisted of 0 or 80 kg ha-1 of total P2O5 applied on the soil surface, both as natural reactive phosphate (NRP) or triple super phosphate (TSP). In addition, 80 kg ha-1 of P2O5 were applied to subplots, in furrows below and beside the soybean (Glycine max L.) seeds, in different combinations of NRP and TSP. Soil samples were taken before and after the soybean growth, down to 0.40 m and soil phosphorus was chemically fractionated. The responses to NRP were similar to TSP, with an increase in P reserves at greater depths, even in non-available forms, such as P-occluded. After the soybean harvest, P-occluded levels were lower at the surface layer, but an increase was observed in the soluble, organic and total P down to 40 cm. An improved P distribution in soil depth, especially regarding the soluble and organic forms, resulted in higher soybean yields, even when the phosphates were applied to the soil surface.Em semeadura direta o fósforo (P) acumula-se na camada mais superficial do solo, mas os resíduos deixados na superfície liberam P e ácidos orgânicos, que podem melhorar a disponibilidade e a eficiência de fertilizantes como o superfosfato triplo e fosfatos naturais reativos. Neste estudo, a resposta da soja à adubação com P e as formas de P até 40 cm de profundidade do solo foram avaliadas após a aplicação de fosfatos em um sistema conduzido em semeadura direta há cinco anos. Os tratamentos consistiram de 0 ou 80 kg ha-1 P2O5 total, aplicados na superfície do solo como fosfato natural reativo (FNR) ou superfosfato triplo (SFT). Nas subparcelas foram aplicados, no sulco de semeadura, 80 kg ha-1 de P2O5, em diferentes combinações de FNR e SFT. Amostras de solo foram coletadas até 0.4 m, antes e depois do cultivo da soja (Glycine max L.), para fracionamento do P. As respostas ao FNR foram semelhantes às do SFT, com aumento das reservas de P em profundidade, mesmo em formas não-disponíveis como P-ocluso. Após a colheita da soja, os teores de P-ocluso diminuíram na camada mais superficial, mas foi observado um aumento nas formas solúvel, orgânica e P - total em toda a espessura de solo estudada. A melhor distribuição do P no solo, principalmente em formas solúvel e orgânica, resultou em maior produtividade da soja, mesmo quando o fertilizante foi aplicado na superfície do solo
