Esses são responsáveis por controles preventivos e curativos das plantas cultivadas em relação a problemas causados por insetos-pragas, doenças e plantas daninhas, porém, deve-se evitar a contaminação ambiental, humana e do alimento por meio da deriva, que é a perda do produto fitossanitário aplicado para locais não desejados. Para que essa deriva seja evitada, busca-se adquirir um conhecimento do comportamento das gotas após as pulverizações, principalmente em aplicações aéreas, onde as condições climáticas são ainda mais determinantes. Neste contexto, o objetivo dessa pesquisa foi analisar, comparativamente, os métodos de coleta de dados para modelagem de deriva com coletores horizontais e verticais em pulverizações de gotas finas e médias, visando analisar as implicações da escolha de um dos métodos e correlacionar os dados obtidos em ambas as metodologias em aplicação aérea. Foram avaliados dois tratamentos com quatro repetições, com gotas finas (GF) e médias (GM) pulverizadas com uma aeronave Ipanema e ponta de pulverização CP-03, em que foi pulverizada uma calda contendo uma concentração de inseticida em mistura ao corante azul brilhante. A deriva foi avaliada fora da área aplicada, na direção do vento predominante, por meio de coletores horizontais (lâminas de vidro) e coletores verticais (fios de nylon) distribuídos até 500 metros em relação à área aplicada. Os dados do índice de deriva foram calculados por meio de espectrofotometria e as médias do índice de deriva foram agrupados e ajustados para uma curva (modelo) através das médias e correlacionados a partir do coeficiente de Pearson a 5% de probabilidade. Nos dois tipos de coletores avaliados o tratamento com gotas finas (GF) apresentou maior valor de deriva comparado ao tratamento com gotas médias (GM). Na coleta vertical, o tratamento GM propiciou índices de deriva 50,0% menores na comparação direta com o GF e na coleta horizontal o tratamento GM propiciou índices de deriva 56,8% menores na comparação direta com o GF. A partir do ponto a 380 metros até a distância de 500 metros da área aplicada foi observada uma inflexão, em que o índice de deriva capturado nos coletores horizontais passa a ser maior para o tratamento GM. Nas correlações para avaliar o comportamento dos diferentes coletores para os tratamentos testados foi possível observar que para ambos os coletores a correlação foi significativa e positiva somente para o tratamento GM. É conclusivo, para esse estudo, que para o tratamento GM os dois tipos de coletores estudados apresentam correlação significativa e positiva a variação do índice de deriva. As gotas finas permanecem na corrente de ar por maiores distâncias e os coletores horizontais são ineficientes na coleta dessas gotas em tal camada, sendo os coletores verticais o melhor método para a coleta da deriva em aplicação aérea, por não haver inflexão nos tratamentos analisados e por apresentarem uma boa eficiência na coleta dos tratamentos com gotas finas e médias. / Modern large-scale agricultural production is not possible without the use of pesticides. These products are responsible for the maintenance, prevention and protection of crops against problems caused by pests, diseases and weeds. Additionally, a great deal of care has been taken to avoid the environmental, human and food contamination from spray drift, which is defined as the loss of applied pesticide to undesirable locations. To achieve this goal, knowledge of the behavior of droplets after the spraying, especially in aerial application, is even more crucial given the greater effect of climatic conditions. Thus, the aim of this study was to comparatively analyze the methods of data collection for modeling spray drift in aerial application with horizontal and vertical collectors in order to analyze the implications of the choice of a method and correlate the data obtained in both methodologies. Two treatments with four repetitions, a Fine spray (GF) and a Medium spray (GM), were used. The treatments were made using an aircraft (Ipanema) equipped with CP nozzles, and sprayed insecticide + Brilliant Blue dye as the spray solution. The drift was evaluated downwind from the applied area, using horizontal collectors (glass slides) and vertical collectors (nylon strings) positioned at distances up to 500 meters downwind of the applied area. The data for the drift index were determined from the spectrophotometry method and averages of the drift index were grouped and adjusted to a curve (model) through the averages and correlated the data from the Pearson Coefficient at a 5% probability. Results showed that with both collector types higher drift values were observed with the Fine spray than the treatment with the Medium spray. Results from the vertical collectors showed that the treatment with the Medium spray had a drift index 50.0% lower than the treatment with the Fine spray. Results from the horizontal collectors showed that the treatment with the Medium spray had a drift index 56.8% lower than the treatment with the Fine spray. From the collector at 380 meters downwind until 500 meters downwind from the applied area resulted in an inversion, where the drift index collected from the horizontal collectors was larger with the Medium spray treatment than the Fine spray treatment. When the correlations were calculated, the results for both collector types showed a significant and positive correlation only to Medium spray. It is conclusive from this study that to Medium spray to both types of the collectors showed significant and positive correlation the variation of the drift index. The Fine spray remained suspended in the air for longer distances and the horizontal collectors were unable to collect them in these conditions. The vertical collectors were the best method to capture drifting droplets in aerial application, given the lack of inversion from the treatments and in part from the good collection efficiency with both the Medium and Fine spray treatments.

O trabalho foi conduzido no Depto. Fitossanidade - UNESP, Jaboticabal, em frutos de laranja infestados artificialmente com ácaros criados em câmara climatizada. Testou-se o efeito residual e tópico de propargite e verificou-se que o acaricida possui ambos os efeitos. Investigou-se o efeito da cobertura de frutos com pulverização da calda dos acaricidas: cyhexatin, óxido de fenbutatina, dinocap e propargite na concentração comercial e metade desta. Verificaram-se efeitos diferenciados, sendo a maior eficiência verificada para o cyhexatin e a maior migração dos ácaros da área tratada para o óxido de fenbutatina. Neste ensaio foi confirmado que quanto maior a área do fruto tratada maior a mortalidade dos ácaros. Determinou-se, então a cobertura mínima com base no tamanho e número de gotas a ser depositada para obtenção de controle satisfatório do ácaro. Utilizou-se o acaricida propargite nas concentrações de 0,036%, 0,072%, com e sem espalhante-adesionante e 0,144% sem espalhante-adesionante. Verificou-se que a adição do espalhante-adesionante prejudicou o efeito acaricida da calda. A cobertura mínima necessária para o controle do ácaro com a calda de propargite a 0,072% determinada no trabalho, foi resultante de 18 gotas de 293 æm por centímetro quadrado. / The aim of this research work was to identify the minimum adequate spray coverage number and size to control the mite Brevipalpus phoenicis. The research was conducted at Department of Crop Protection - UNESP, Jaboticabal, using oranges artificially infested by mites reared in a controlled chamber. Residual and topical actions of propargite were tested and it was observed that the mitecide has both of effects. Effects of fruit coverage with spray of mitecides: cyhexatin, fenbutatin oxide, dinocap and propargite were investigated using the commercially recommended dosage rate and half of this dosage. It was verified that the effects varied being cyhexatin the most effective and fenbutatin oxide causing more escape of mites from treated area. In this trial was confirmed that larger the sprayed area higher was the mortality of mites. Minimum effective coverage was studied using 0.036% and 0.072% propargite solution, with and without spreader-sticker and 0.144% without the spreader-sticker. It was verified that addition of the spreader-sticker had detrimental effect on mitecide action. The minimum spray coverage to achieve control of the mite using 0.072% propargite solution determined in this work is 18 droplets of 293 æm per square centimeter.

Feasibility of a Mobile Meditation Application to Improve Psychological Factors Affecting Performance in Baseball Players

January 2018 (has links)
abstract: Pitchers are a vital part of the game of baseball and may account for up to two-thirds of the variance in win percentage. As they rise through the ranks of competition, physical skill set becomes less of a factor when compared to mentality. Pitchers are the “first line of defense” for keeping opponents from having an opportunity to score, as well as for holding onto their own team’s lead. Baseball pitchers not only face pressure to perform, but also experience stress from factors such as low pay, adjusting to higher levels of competition, and internal team competition for a limited number of spots. Athletes are often resistant to seeking aid from sport psychologists and often turn to unfavorable means to cope (i.e. drugs/alcohol, excessive exercise) with stress instead. Meditation has been shown to have beneficial effects on psychological factors associated with performance including emotional regulation, anxiety, confidence, focus, and mindfulness. Mobile applications have become a popular means of delivering mindfulness. The purpose of this study was to determine the feasibility and preliminary effectiveness of delivering a mindful meditation intervention using a mobile meditation application to improve psychological factors associated with performance (i.e. emotional regulation, anxiety (somatic and cognitive), confidence, focus, mindfulness) to minor league baseball pitchers. Pitchers in instructional league (Phase one) and off season (Phase two) were asked to meditate daily for 10-minutes each day for three weeks (Phase one) and eight weeks (Phase two). Pitchers were asked to complete self-report questionnaires and satisfaction surveys at pre- and post-intervention. Pitchers in phase one reported enjoying meditation, had improvements in self-confidence and sport confidence, and reported moderate decreases in cognitive anxiety and concentration disruption. Pitchers in phase two also enjoyed meditating (94.7%) and had improvements in self-confidence and moderate decreases in somatic anxiety. Low adherence due to timing (off-season) of intervention may have been a contributing factor to fewer outcomes. Future research should explore the feasibility and effectiveness of implementing meditation during the baseball season. / Dissertation/Thesis / Masters Thesis Exercise and Wellness 2018

Cobertura da cultura da soja e deposição de insiticida aplicado com e sem adjuvante e diferentes equipamentos e volumes de calda /

Di Oliveira, José Rodolfo Guimarães. January 2008 (has links)
Orientador: Marcelo da Costa Ferreira / Banca: Adeney de Freitas Bueno / Banca: Júlio César Galli / Resumo: Objetivou-se avaliar o espectro, a deposição e cobertura das gotas de pulverização em função de equipamentos, volumes de calda, adjuvantes e dosagem de inseticida na mortalidade de Pseudoplusia includens. No laboratório realizou-se uma aplicação sobre as lagartas com os tratamentos: 2 equipamentos (bico rotativo e hidráulico) 2 volumes de calda (17 e 50 L ha-1 com o bico rotativo e 50 e 100 L ha-1 com o bico hidráulico), 2 dosagens do inseticida endosulfan (0,5 e 1,0 L pc ha-1), e 1 testemunha, seguindo o delineamento inteiramente casualizado. O experimento de campo foi realizado na fazenda da UNESP/Jaboticabal nas safras 2006/07 e 2007/08, em blocos casualizados com: 2 equipamentos (bico hidráulico e rotativo), 3 volumes de aplicação (50; 75; e 100 L ha-1 com o bico hidráulico e 17; 35; e 50 L ha-1 com o bico rotativo), aplicação com e sem adjuvante e 1 testemunha. Avaliou-se o número de lagartas vivas, a cobertura das gotas no papel hidrossensível, a deposição nas folhas de soja, e o espectro das gotas aspergidas utilizando um aparelho medidor de tamanho de partículas em tempo real do Laboratório de Análise do Tamanho de Partículas, do Departamento de Fitossanidade UNESP/Jaboticabal. Verificou-se que o volume de calda pode ser reduzido sem prejudicar o controle de P. includens, a dosagem de 0,5 L pc ha-1 não controla a lagarta-falsa-medideira em laboratório. Em campo, a melhor cobertura, deposição e mortalidade das lagartas foram alcançadas utilizando-se volume de 75 L ha-1 com o bico TT 11001, com a adição de adjuvante. O bico rotativo produz gotas de maior uniformidade e menor porcentagem de gotas suscetíveis à deriva, em relação ao bico hidráulico. A adição de adjuvantes promove gotas de maior tamanho e menos suscetíveis á deriva. / Abstract: The aim of this work was to evaluate the spectrum, the deposition and coverage of droplets of spray due equipment, spray volumes, surfactans and dosage of insecticide in mortality of Pseudoplusia includens. The application in laboratory was done over the caterpillars with the tr~atments: 2 equipment (atomizer and hydraulic nozzles) 2 spray volumes (17 and 50 L ha-1 with the atomizer and 50 and 100 L ha-1 with the hydraulic nozzle), 2 doses of the insecticide endosulfan (0.5 and 1.0 L pc ha-1), and 1 untreated check, following the randomized plots. Was evaluated, the mortality of caterpillars, and the spectrum of droplets. The experiment was carried out in field with randomized blocks: 2 equipment (hydraulic nozzle and atomizer), 3 spray volumes (50, 75, and 100 L ha-1 with hydraulic nozzle and 17, 35 and 50 L ha-1 with atomizer), with and without adjuvant application and 1 untreated check. Was evaluated, the number of alive caterpillars, the coverage of droplets on sensitive paper, deposition on leaves of soybean, and the spectrum of droplets sprayed using in a particle size analyzer in real time. It was observed that spray volume in the laboratory can be reduced without harming the control of P. includens. The dos age of 0.5 L pc ha-1 does not controled satisfactorily the soybean looper caterpillar. On the field, the best coverage, deposition and controlled of caterpillar is achieved using a volume of 75 L ha-1 with hydraulic nozzle TI 11001, with addition of adjuvant. The atomizer produces droplets of more uniformity and less susceptibility to the percentage of droplets to drift, than hydraulic nozzle. The addition of adjuvants results in increase of droplets size and reducing susceptibility to drift. / Mestre

DNA Nanostructure as a Scaffold for Immunological Applications

January 2012 (has links)
abstract: DNA nanotechnology has been a rapidly growing research field in the recent decades, and there have been extensive efforts to construct various types of highly programmable and robust DNA nanostructures. Due to the advantage that DNA nanostructure can be used to organize biochemical molecules with precisely controlled spatial resolution, herein we used DNA nanostructure as a scaffold for biological applications. Targeted cell-cell interaction was reconstituted through a DNA scaffolded multivalent bispecific aptamer, which may lead to promising potentials in tumor therapeutics. In addition a synthetic vaccine was constructed using DNA nanostructure as a platform to assemble both model antigen and immunoadjuvant together, and strong antibody response was demonstrated in vivo, highlighting the potential of DNA nanostructures to serve as a new platform for vaccine construction, and therefore a DNA scaffolded hapten vaccine is further constructed and tested for its antibody response. Taken together, my research demonstrated the potential of DNA nanostructure to serve as a general platform for immunological applications. / Dissertation/Thesis / Movie 4.1-a / Movie 4.1-b / Movie 4.1-c / Ph.D. Biochemistry 2012
