The Master thesis dealt with changes in cytoplasmatic membrane of model strain Streptomyces nodosus subsp. asukaensis. This strain produces polyketide antibiotic called asukamycin. Changes of cytoplasmatic membrane were observed as a response to the age of bacterial culture (exponential and stationary growth phase) and addition of produced antibiotic precursor (cyclohexanecarboxylic acid) to incubation medium. Observed parametres were the composition of membrane fatty acids and the membrane fluidity.

O trabalho apresenta uma proposta metodológica para caracterização de aptidões e restrições do meio físico, considerando a variação contínua dos atributos e também a existência de gradação nos contatos entre as unidades. Os mapas do substrato rochoso e dos materiais inconsolidados foram obtidos utilizando-se de procedimentos da lógica fuzzy para representação da gradação nos contatos. As cartas de declividade, de menor extensão do percurso da água superficial, de potencial de escoamento superficial, de susceptibilidade à erosão e de potencial agrícola foram obtidas utilizando-se mapas numéricos e a variação contínua dos atributos. Para realização das operações de geoprocessamento foram utilizados o sistema de informação geográfica SPRING e a linguagem de programação LEGAL, que permitiram, tanto a representação dos contatos gradacionais (fuzzy) quanto a classificação contínua e o cruzamento das informações. Para avaliação de alterações introduzidas no meio, foi proposta a aplicação do atributo resistência à penetração do solo como geoindicador ambiental. As medidas de resistência à penetração foram feitas utilizando-se um novo equipamento, que consiste de um penetrômetro de solo acoplado a uma sonda TDR. Este procedimento permitiu a caracterização de modificações das condições naturais de compactação dos solos da bacia, frente às atividades de uso do terreno vigentes, bem como forneceu um parâmetro para comparação frente a modificações de uso futuras. O zoneamento da área foi obtido a partir da adoção das unidades de lanforms como unidades de compartimentação, o que possibilitou a caracterização das aptidões, restrições e conflitos de uso / This study presents a methodological technique to characterize environmental restrictions and aptitudes considering continuous variation in the attributes and gradation in contato between units. Fuzzy logic procedures were used to generate representation of contact gradation for rocky substratum and unconsolidated materials maps. Continuous attribute variation and numerical maps were used to produce slope least water runoff distance, runoff potential, erosion susceptibility and agricultural potential charts. Geoprocessing operations using the SPRING geographical information system and its LEGAL programming language permitted the representation of gradation in contac (fuzzy), continuous classification nad information crossing. Soil penetration resistance was proposed as the environmental geondicator to evaluate environmental changes. Measurement of soil penetration resistance by a soil penetrometer connected to a TDR proble permitted the characterization and specification of natural basin soil compaction conditions and the comparison of different occupation activities on the soil. A parameter for future changes due to soil occupation was therefore identified by this procedure. Area zoning was attained by the adoption of landform units as segmentation units. The characterization of aptitudes, restrictions and conflicts in occupation were achived by this procedure

As pastagens ocupam a maior parte da área agrícola e contribuem com a segunda e a quinta atividades que compõem o PIB agropecuário brasileiro, a carne e o leite. A crescente utilização da irrigação de pastagens surgiu primordialmente em áreas leiteiras, juntamente com processos que aprimoram a produção, e posteriormente espalhou-se por áreas de gado de corte. Assim surge a necessidade de um manejo adequado da irrigação de pastagens, e é fundamental conhecer sua evapotranspiração, seus limites produtivos e suas caracteristicas nesse processo de intensificação. Portanto, o objetivo deste trabalho foi determinar o consumo de água, os valores do coeficiente de cultura (Kc) e os parâmetros produtivos e biométricos de duas gramíneas tropicais (Panicum maximum cv. Mombaça e Cynodon spp.), em cultivos exclusivos e consorciados em sobressemeadura com aveia preta e azevém. Como objetivos secundários, buscou-se: (i) medir os parâmetros biométricos de altura do dossel forrageiro (ADF) e indice de area foliar (IAF) entre os ciclos identificando o melhor período de corte, (ii) estimar o acúmulo médio de graus dias de desenvolvimento (GDD) nas diferentes estações do ano correlacionando com o crescimento das forrageiras, (iii) estimar o consumo de água das plantas com a sonda FDR Diviner 2000® e correlacionar seus dados com o consumo de água medido em lisímetros de pesagem. O estudo foi realizado na Escola Superior de Agricultura \"Luiz de Queiroz\" (ESALQ/USP) em Piracicaba-SP (Latitude 22°42\'14\"S; Longitude 47°37\'24\"O; Altitude de 569 m). Os experimentos foram conduzidos de março de 2015 a fevereiro de 2017, com delineamento experimental de blocos ao acaso com 4 tratamentos: 1- capim Mombaça em cultivo exclusivo, 2- capim Mombaça em cultivo sobressemeado com aveia e azevém, 3 - Cynodon spp em cultivo exclusivo; 4 - Cynodon spp em cultivo sobressemeado com aveia e azevém. Foram utilizados a aveia preta (Avena strigosa) cv. Embrapa 29 (Garoa) e azevém (Lolium multiflorum) cv. Fepagro São Gabriel. As calibrações dos métodos de lisimetria e da sonda FDR (Diviner 2000®) apresentaram bons ajustes, com altos coeficientes de correlação. Os resultados de consumo de água pelas gramíneas mostraram uma grande variação por período e dentro dos ciclos com grandes consumos de água, obtendo vários valores de Kc maiores que 1. Foram obtidas boas correlações entre crescimento, IAF e acúmulo de graus dias (GDD). Os valores acumulados de evapotranspiração de cultura (Kc) obtidos com o sensor FDR foram maiores que os medidos nos lisímetros. Os resultados detalhados encontram-se no desenvolvimento de cada capítulo deste trabalho. / Pastures represent the largest part of the agricultural area and contribute to the second and fifth activities that make up the Brazilian GPD, meat and milk. The increasing use of pasture irrigation primarily arose in dairy areas, along with processes that improve the production, and subsequently reache areas of beef cattle. Thus, there is a need for an adequate irrigation management, and it is fundamental to know the crop evapotranspiration of pastures, their productive limits and their characteristics in this intensification process. Therefore, this work aimed to determine the crop water consumption, the values of crop coefficient (Kc), and the productive and biometric parameters of two tropical grasses (Panicum maximum cv. \'Mombasa\' and Cynodon spp.) single cropped and intercropped in oversseeding with black oats and ryegrass . As secondary goals, it sought: (i) measuring the biometric parameters of forage canopy height (ADF) and leaf area index (LAI) between the cycles, identifying the best cutting period; (ii) estimating the mean accumulation of degree-days of development (GDD) in the different seasons, correlating them with forage growth; (iii) estimating the crop water consumption with the FDR probe Diviner 2000® and correlating its data with the crop water consumption measured on weighing lysimeters. The study was carried out at the \"Luiz de Queiroz\" College of Agriculture (ESALQ/USP), at Piracicaba, SP (Latitude 22°42\'14\"S; Longitude 47°37\'24\"W; Altitude de 569 m a.s.l.). The experiments were conducted from March 2015 to February 2017, with a randomized complete block design with 4 treatments: 1 - single cropped \'Mombasa guinea grass ; 2- \'Mombasa\' guinea grass intercropped with oats and ryegrass; 3 - single cropped Cynodon spp.; 4 - Cynodon spp. intercropped with oats and ryegrass. The winter forages were black oats (Avena strigosa) cv. Embrapa 29 (Garoa) and ryegrass (Lolium multiflorum) cv. Fepagro São Gabriel. The calibrations of the lysimeters and the FDR probe had good adjustments, with high correlation coefficients. The results obtained of crop water consumption by the grasses showed a great variation by period and inside the growing cycles with great water consumption, often obtaining Kc values above 1. Good correlations were obtained between crop growth, LAI and degrees-days accumulation (GDD). The accumulated values of crop coefficient (Kc) were higher with the FDR sensor than with the lysimeters. The detailed results can be found in the chapters of this work.

Master’s thesis deals with the design of monitoring of handling equipment. Measured quantities are the switched-on state of the forklift, the time of active use, monitoring of transported material, and the total traveled distance. For each quantity, several possible sensing methods are outlined followed by a summary of the pros and cons of each method, which served as the basis for selecting the most suitable sensor for sensing the required information. The theoretical part of the thesis outlines the proposals in terms of both theoretical aspects as well as the implementation of the sensors along with proposals for possible mounting on a forklift. The proposed application was built on top of the Workmonitor RKC2.0 development kit, which was first developed for injection molding machine monitoring equipment. The proposed solution further expands the Workmonitor RKC2.0 software with additional features, such as forklift data collection, data processing, and streaming of collected data via WiFi to a local server. The final part then describes the mounting of sensors in the forklift, the final software changes, and the presentation of the collected data.
