No. of bitstreams: 1 FABIANO PEREIRA CAVALCANTE – TESE (UAEMa) 2016.pdf: 9796097 bytes, checksum: 383028e550cf57512a5833a1e68df7d9 (MD5) Previous issue date: 2016-02-29 / A redução das temperaturas durante a produção e a aplicação das misturas betuminosas proporciona benefícios de sustentabilidade evidentes a curto, médio e longo prazo, os quais estão relacionados a impactos positivos sociais, econômicos e ambientais. Os aditivos naturais com origem em oleaginosas, tais como: a palma, a soja, o girassol, o amendoim, a linhaça e a mamona se constituem, potencialmente, como agentes viáveis para a redução da temperatura de usinagem e de compactação (TUC) ao serem incorporados ao CAP que integrará as misturas asfálticas. Este trabalho teve como objetivo o estudo dos efeitos da adição de oleaginosas, tais como o óleo de Mamona e o de Linhaça, sobre as Propriedades Reológicas dos Cimentos Asfálticos de Petróleo. Foram observados os comportamentos reológicos dos CAPs convencional (CAP 50/70) e modificado (CAP 55/75) considerando percentuais de 4%, 5% e 6% de óleo, bem como as propriedades mecânicas das misturas asfálticas dosadas pelos procedimentos Marshall e Superpave. Os resultados reológicos dos CAPs com a adição do óleo de Linhaça apresentaram valores melhores do que aqueles obtidos com a adição do óleo de Mamona, segundo os parâmetros relacionados aos ensaios de penetração, de ponto de amolecimento, de viscosidade rotacional e de reologia (MSCR) quando as mostras foram submetidas ao envelhecimento a curto prazo (RTFO). Para as misturas asfálticas estudadas foram obtidas uma melhor adesividade e coesão, com consequente maior resistência à ação deletéria da água quando os corpos de provas foram submetidos ao ensaio de dano por umidade induzida (Lottman modificado) e ao ensaio de desgaste Cântabro, cujos resultados foram significativamente superiores aos das misturas compostas por CAPs na condição natural. Infere-se que as oleaginosas, na proporção estudada de 5%, podem ser utilizadas como aditivos, a fim de melhorar as propriedades reológicas dos Cimentos Asfálticos, convencional e modificado, com significativa diminuição do poder oxidativo inerente ao aumento de temperatura e, consequentemente, melhoria das propriedades mecânicas das misturas asfálticas. / The decrease in temperature during the production and application of asphalt provides evident sustainability benefits, in the short, medium and long term, which are related to social, economic and environmental positive impacts. Natural additives derived from oilseeds such as palm, soy, sunflower, peanut, linseed and castor beans are potential viable agents to reduce the mixing and compaction temperature (TUC) to be incorporated into the CAP that will make the asphalt mixtures. This study a ims to analyze the effects of adding oil, especially the Castor and linseed oil, on the Rheological Properties of the Petroleum Asphalt Cement. Conventional rheological behavior CAPs were observed (CAP 50/70) and modified (CAP 55/75) considering percentage of 4%, 5% and 6% of the oil, as well as the mechanical properties of asphalt mixtures dosage by Marshall and Superpave procedures. The rheological results of CAPs with the addition of linseed oil showed better results than those obtained with the addition of Castor beans oil, according to the parameters related to the penetration tests, softening point, rotational viscosity and rheology (MSCR), when the samples were subjected to short-term ageing (RTFO). For the asphalt mixtures, it was obtained a better adhesion and cohesion what resulted in a greater resistance to deleterious action of water when the test samples were subjected to induced moisture damage test (modified Lottman) and the Cantabro wear test whose results were significantly better compared to the blends with CAPs in natural condition. It can be inferred that the oilseeds, in the proportion of 5%, can be used as additives for improving the rheological properties of asphalt, conventional and modified Cement, with a significant reduction in oxidative power inherent to temperature increase, and, consequently, with the improvement of mechanical properties of asphalt mixtures.

Factors regulating the expression and activity of digestive enzymes in the tick \kur{Ixodes ricinus} / Factors regulating the expression and activity of digestive enzymes in the tick \kur{Ixodes ricinus}

KONVIČKOVÁ, Jitka January 2015 (has links)
The intracellular proteolysis of ingested meal plays an essential role in tick development. The thesis focuses on the factors influencing the expressions and activities of digestive enzymes in Ixodes ricinus females during the feeding and post-feeding period. We have revealed the effect of fertilization on blood feeding and digestion. The females cannot reach the rapid engorgement phase without being fertilized. The rate of mated females in the nature proved the presumption that mating can occur even off the host. Implementation of in vitro feeding technique further extended our current knowledge about tick digestive apparatus. Adult females were fed on hemoglobin-rich and hemoglobin-poor diet and the mRNA expression levels of digestive proteases were determined. In line with obtained data, we assumed that albuminolysis is conducted by the same or similar pathway as hemoglobinolysis. The gene silencing method and protein immuno-detection were used to unequivocally identify the isoforms of 'early expressed' IrCL1 and 'late expressed' IrCL3 isoform of cathepsin L.

In the Northeast of Brazil it is commonly cultivated by small farmers intercropped with cotton, cowpea, sesamum, sunflower, sorghum or peanuts. Two field experiments were carried during 2008, 2009 and 2010, at “ Fazenda Experiental Lavoura Seca”, Quixada, Ceara, with the objective to evaluate the behavior of castor bean and sunflower under two intercropping arrangements. In experiment I, its was evaluated the intercropping castor bean (CB) x sunflower (SF) with 1CB:1SF; 1CB:2SF; 1CB:3SF; 2SB:2SF; 2CB:3SF rows, added of sole crop of castor bean and sunflower. In the experiment II, was evaluated with the early planting of castor bean in 0, 7, 14 or 21 days in relations to sunflower the intercropping systems. In both experiments it was used a randomized complete block design with 4 replications. In this study it was determined the yield, yield components and land equivalent ratio (LER) for castor bean and sunflower grown in intercropping and sole crop. The grain yield of castor bean and sunflower was significantly higher in sole crop than intercropping in both experiments. Between the intercropping systems the highest yields were observed when early planting of castor bean was of 14 or 21 days before sunflower. In experiments I and II, showed that the castor bean was the dominant crop in relation to sunflower. Rainfall lower the water requirements of castor bean and sunflower crops, showed a reduction in LER. / A mamoneira (Ricinus communis) é tolerante a seca e cultivada para produção de óleo para uso industrial. Na região Nordeste os pequenos produtores cultivam a mamona consorciada algodão, feijão caupi, gergelim, girassol, milho, sorgo ou amendoim. Dois experimentos de campo foram conduzidos nos anos agrícolas 2008, 2009 e 2010, na Fazenda Experimental Lavoura Seca, Quixadá, Ceará, com o objetivo de avaliar o comportamento da mamona e girasssol cultivados em dois padrões de consorciação. No experimento I avaliou-se o consorcio mamona (Ma) x girassol (Gi) com 1Ma:1Gi; 1Ma:2Gi; 1Ma:3Gi; 2Ma:2Gi; 2Ma:3Gi fileiras, acrescidos da mamona e girassol em monocultivo. No experimento II, avaliou-se o consorcio mamona x girassol com antecipação do plantio da mamona em 0, 7, 14 ou 21 dias antes do plantio do girassol. Para cada experimento adotou-se o delineamento de blocos ao acaso com 4 repetições. Avaliou-se a produtividade de grãos, seus componentes e o uso eficiente da terra para a mamona e girassol consorciados e em monocultivo. A produtividade da mamona e girassol no monocultivo foi significativamente superior nos dois sistemas de consórcio. A antecipação do plantio da mamona 14 e 21 dias em comparação ao girassol mostraram vantagens em relação as demais datas de plantio. No experimentos I e II verificou-se que a mamona foi dominante sobre ao girassol. Precipitações pluviais inferiores a demanda hídrica das culturas da mamona e girassol, proporcionaram redução no uso eficiente de terra (UET).

Para isto, dois experimentos foram desenvolvidos em ambiente protegido, usando em cada um deles um delineamento experimental inteiramente casualizado, constituído cada um por uma cultivar de mamona e oito tratamentos de fertilização, num fatorial 2x2x2 da combinação N-P-K, sendo duas doses de N (Ni=200 e N2= 300 kg/ha), duas doses de P (Pi=150 e P2=250 kg/ha) e duas doses de K (Ki=150 e K2=250 kg/ha), com três repetições, totalizando 24 unidades experimentais. A testemunha correspondeu as menores doses estudadas (NjPiKi). O conteúdo de água do solo foi mantido a capacidade de campo e monitorado diariamente através de uma sonda DrVTNNER, inserida no solo através de um tubo de acesso instalado em cada vaso. Aos 20, 40, 60, 80, 100, 120, 140 e 160 dias após a semeadura foram avaliados a altura da planta, diâmetro caulinar, fitomassa e o numero e comprimento de folhas. A produção da cultura foi avaliada medindo o comprimento e o peso do racemo, número de frutos e quantidades de sementes por racemo, peso de 100 sementes e teor de óleo e proteína bruta. A aplicação das maiores doses de nitrogénio, fósforo e potássio de forma combinada não foi suficiente para as plantas desenvolverem todo o seu potencial produtivo. O nitrogénio foi o nutriente mais eficiente no crescimento, desenvolvimento e na produção das duas cultivares de mamonas estudadas. As cultivares, em plena frutificação, apresentaram carência de nitrogênio, fósforo, potássio, cálcio e enxofre e elevados teores de magnésio. Independente das dosagens de NPK estudadas, o teor de óleo nas sementes foi menor que o teor admitido como ideal para a mamona, mas, apesar de inferior ao valor mínimo exigido o nitrogênio promoveu aumento nos teores de óleo da planta. As doses de nitrogênio exerceram efeito significativo na produção de proteína bruta. / The fertilization is a practice that normally increases the productivity of the cultures. Considering that the NPK needs of the castor bean are still unknown an study was conducted aiming to evaluate the effects of nitrogen, phosphorus and potassium on the growth and production of castor bean (Ricinus communis L.) cultivar BRS 188 Nordestina and BRS 149 Paraguaçu. For this, two experiments were installed in a greenhouse using a 2 x 2 x 2 factorial design completely randomized subjected to two leveis of nitrogen (Ni=200 and N2=300 kg ha"1), two leveis of phosphorus (Pi=150 and P2=250 kg ha"1) and two leveis of potassium (Ki=150 and K2=250 kg ha'1) with three replicates, totalizing 24 experimental units. The testimony corresponded to the treatment with the lowest leveis of NPK (N1P1K1). Soil water content was maintained at field capacity and monitored daily using a DIVTNER probe inserted into the soil throughout an access tube installed in each vase. Plant height, stem diameter, number and length of leaves were measured at 20, 40, 60, 80, 100,120, 140 and 160 days after planting. Castor bean production was evaluated measuring the length and weight of the raceme, the number of fruits, the amount of seeds by raceme, weight of 100 seeds, and oil and protein content of the seed. The combined application of the highest leveis of nitrogen, phosphorus and potassium was not enough for the plants to develop its productive potential. Nitrogen was the nutrient that promoted the highest growth, development and yield of the two cultivars. On fructification, both castor beans cultivars presented low content of nitrogen, phosphorus, potassium, calcium and sulfur and high contents of magnesium. Independently of the NPK leveis studied, the oil content of the seeds was under the ideal and admitted levei. Although the oil content of the seed was low, the nitrogen application increased the seed oil content. The application of nitrogen increased significantly the protein production.

Orientador: Maurício Dutra Zanotto / Banca: Mirian Luiza Myczkowski / Banca: Flávio Rielli Mazetto / Banca: José Geraldo Carvalho do Amaral / Resumo: A mamoneira (Ricinus communis L.) é uma planta oleaginosa de alto valor econômico. O óleo extraído de suas sementes é um dos mais versáteis encontrado na natureza; apresenta inúmeras aplicações em diversas áreas, podendo substituir de forma satisfatória o uso do petróleo em muitos produtos. Atualmente existe um grande interesse em aumentar a produtividade da planta mediante o aumento do número de flores femininas (pistiladas) que, conseqüentemente, aumentará o número de frutos e de sementes. Dessa forma, o objetivo desse trabalho foi através do método de melhoramento denominado seleção massal, selecionar e avaliar plantas de mamoneira da população FCA-UNESP-PB (porte baixo) para aumento da freqüência de flores femininas visando maior produtividade final. A seleção (ciclo de seleção) foi feita no ano de 2007 na fazenda Experimental Lageado e avaliada (ciclo de avaliação) em 2008 nas Fazendas Experimentais Lageado e São Manuel, ambas pertencentes à Faculdade de Ciências Agronômicas - UNESP - campus Botucatu e localizadas, respectivamente, nos municípios de Botucatu - SP e São Manuel - SP. O critério de seleção foram plantas que apresentaram 100% de flores femininas no racemo primário. As plantas com esse fenótipo que sofreram reversão sexual durante o ciclo de desenvolvimento, tiveram seus racemos autofecundados assim que passaram a produzir flores masculinas (estaminadas). Para o ciclo de avaliação foram colhidas sementes do racemo primário das plantas selecionadas com 100% de flores femininas - tratamento 1 (aberto);sementes dos racemos autofecundados dessas plantas inicialmente 100% femininas - tratamento 2 (autofecundado) e sementes colhidas ao acaso que serviram de controle - tratamento 3 (controle).

The oil extracted from its seeds is one of the most versatile found in nature, has many applications in different areas and it can satisfactorily replace the use of petroleum in many products. Currently there is great interest in increasing the grain yield of the plant by increasing the number of female flowers (pistillate) that, consequently, increase the number of fruit and seeds. The objective of this research was through the method called for mass selection, select and evaluates castor bean plants of the population FCA-UNESP-PB (dwarf height) to increase the frequency of female flowers aimed at increasing grain yield. The selection (selection cycle) was conducted in 2007 in Experimental Lageado farm and evaluate (evaluation cycle) in 2008 in Experimental Lageado and Experimental São Manuel farms, both belonging to the Agriculture College of São Paulo State University - UNESP - campus Botucatu, located respectively in Botucatu - SP and São Manuel - SP cities. The selection criterion was plants that had 100% female flowers on the first raceme. Plants with this phenotype had their racemes selfed when they start to produce male (staminate) flowers (sex reversal). For the evaluation cycle were harvested seeds of the first raceme of selected plants with 100% female flowers - treatment 1 (open); seeds of selfed racemes with plants initially 100% female - treatment 2 (selfed) and seeds taken at random who served as control - treatment 3 (control).

Atividade antimicrobiana das soluções de Barbatimão, Mamona e Clorexidina utilizadas na Endodontia. Avaliação comparativa in vitro / Antimicrobial activities of Stryphnodendron adstringens, Ricinus communis detergent and chlorhexidine solutions in Endodontics. In vitro comparative study.

Mauricio Antonio Miranda 26 March 2010 (has links)
No presente trabalho foram avaliadas as atividades antimicrobianas do extrato hidroalcoólico do barbatimão (Stryphnodendron adstringens), do detergente de mamona (Endoquil Poliquil®) e da solução de digluconato de clorexidina a 2% sobre microrganismos bucais potencialmente envolvidos em infecções endodônticas O barbatimão, como é popularmente conhecido, é muito utilizado na medicina popular para o tratamento de algumas enfermidades como a gonorréia, diarréia, úlceras, como antiinflamatório e cicatrizante. O detergente de mamona (Ricinus communis) possui atividade antimicrobiana similar ao do hipoclorito de sódio a 0,5% quando usado no tratamento de canais com polpa necrosada. A clorexidina é muito conhecida por sua atividade antimicrobiana e tem sido utilizada como medicação intracanal, apresentando efeito antimicrobiano residual, ou substantividade, além de baixa toxicidade. Este trabalho tem por objetivo comparar as atividades antimicrobianas destas substâncias pela técnica da difusão (técnica do cilindro) e pela determinação da concentração inibitória mínima (CIM) frente aos seguintes microrganismos: Prevotella nigrescens ATCC 33563, Actinomyces naeslundii (cepa de campo), Actinomyces naeslundii ATCC 19039, Porphyromonas gingivalis (cepa de campo), Porphyromonas gingivalis ATCC 33277, Enterococcus faecalis ATCC 4082, Enterococcus faecalis (cepa de campo), Haemophilus actinomycetemcomitansATCC 43717. Os resultados foram submetidos à análise estatística (ANOVA) e mostraram a atividade antimicrobiana do extrato bruto do barbatimão mais efetivo que o Endoquil® no teste de difusão,mas menor efetividade que a solução de clorexidina 2% em relação a todos os microrganismos utilizados. Conclui-se que o extrato bruto do Stryphnodendron adstringens (barbatimão) apresenta atividade antimicrobiana sobre microrganismos presentes nas infecções endodônticas, segundo os parâmetros empregados nesta pesquisa. / Antimicrobial activities of the hydroalcoholic extract of Barbatimão (Stryphnodendron adstringens), the detergent of castor bean (Endoquil, Poliquil®), and the Chlorhexidine 2% on oral microorganisms potentially involved in endodontic infections were evaluated. The Barbatimão, as it is popularly know, is often used in popular Medicine to treat some diseases like gonorrhea, diarrhea, ulcer, as an anti-inflammatory and cicatrizant. As observed in the literature, the detergent derived from the castor bean oil (Ricinus comunis) has similar antimicrobial activity to the sodium hypochlorite 0.5% when used on the treatment of canals with pulp showing necrosis. The Chlorhexidine is well known for its antimicrobial activity and it has been used as auxiliary solution in Endodontics, showing residual antimicrobial effect, or substantivity, as well as low toxicity. The aim of this study is to compare the antimicrobial activities of those substances by the diffusion technique (cylinder technique) and by determining the minimal inhibitory concentration (MIC) in the following microorganisms: Prevotella nigrescens ATCC 33563, Actinomyces naeslundii (cepa de campo), Actinomyces naeslundii ATCC 19039, Porphyromonas gingivalis (cepa de campo), Porphyromonas gingivalis ATCC 33277, Enterococcus faecalis ATCC 4082, Enterococcus faecalis (cepa de campo), Haemophilus actinomycetemcomitans ATCC 43717. The results were subjected to statistical analysis (ANOVA) and showed that the antimicrobial activity of the raw extract of barbatimão was more effective than the Endoquil®, but still less effective than the Chlorhexidine 2% when compared to all studied microorganisms in agar diffusion method. It can be concluded that the raw extract of Stryphnodendron adstringens (barbatimão) has antimicrobial activities on microorganisms, according to the parameters used in this study.
