Detecção de defeitos em rolamentos atraves do processamento e analise de sinais de vibrações
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro TecnologicoOs métodos de avaliação das condições de operação de máquinas através de monitoramento de vibrações tem desempenhado um importante papel na melhoria do desempenho e disponibilidade do equipamento, além de reduzir os custos de manutenção. Os rolamentos são elementos indispensáveis na maioria das máquinas. Além disso, nos métodos de manutenção convencionais é grande o desperdício de elementos que são substituídos estando ainda em bom estado, porquanto os rolamentos têm uma expectativa de vida tão dispersa que o intervalo entre manutenções deve ser menor que sua vida média, afim de evitar ou diminuir a possibilidade de falha catastrófica. Pelas razões acima, tem sido relatado que os maiores benefícios da instalação de sistema de monitoramento são conseguidos quando aplicados a rolamentos. A Técnica da Análise Espectral e a da Curtose para o monitoramento e diagnóstico de falhas em rolamentos são as mais ostensivamente relatadas. Neste trabalho é apresentado um modelo teórico para a variação do Coeficiente de Curtose com a rotação, além de um modelo simplificado para o espectro de um rolamento com defeito. Também é mostrada a determinação das expressões teóricas para a obtenção das frequências geradas pela rotação. As expressões teóricas para o Coeficente de Curtose foram comparadas com resultados experimentais. A despeito da simplicidade do modelo teórico, através dele puderam-se prever limitações na Técnica da Curtose as quais foram confirmadas pelos resultados experimentais. Dois novos parâmetros que consistem de uma modificação da Curtose foram propostos para melhorar a eficiência da Técnica da Curtose. Finalmente, foi feita uma aplicão simples da Técnica da Análise Espectral
Seminario de posgrado: Una alternativa al capitalismo globalizado: la teoría de la desconexión de Samir Amin
No full textEn este seminario presentamos la teoría de la desconexión de Samir Amin y mostramos su capacidad explicativa en el análisis aplicado a los gobiernos de Juan Domingo Perón (1946-1955) y los de Néstor Kirchner y Cristina Fernández (2003-2015). Samir Amin aporta un valioso marco teórico para la comprensión del funcionamiento del sistema capitalista global a partir de su teoría de los cinco monopolios en disputa: recursos naturales, recursos financieros, investigación científica y técnica, armas de destrucción masiva y medios de comunicación. Según el autor el control estratégico sobre estos recursos permite a los países centrales a través de sus empresas transnacionales apoderarse de los excedentes económicos de los países más débiles mediante la generación de un sistema de precios globales. La desconexión implica en términos económicos el intento de generar en los países y regiones desconectadas, sistemas de precios internos distintos de los globales, de manera tal que se genera un diferente modo de acumulación de riqueza. Lo cual supone recuperar el uso de los instrumentos de regulación del Estado y la posibilidad de distribuir el excedente económico contemplando la integración del tejido social.Neste seminário, apresentamos a teoria da desconexão de Samir Amin e mostramos seu poder explicativo na análise aplicado aos governos de Juan Domingo Perón (1946-1955) e Nestor Kirchner e Cristina Fernandez (2.003-2.015). Samir Amin fornece um quadro teórico valioso para a compreensão do funcionamento do sistema capitalista global a partir de sua teoria dos cinco monopólios em disputa: recursos naturais, recursos financeiros, pesquisa científica e técnica, as armas de destruição em massa e mídia. Segundo o autor, o controle estratégico desses recursos permite que os países centrais, através de suas corporações transnacionais, aproveitem os superávits econômicos dos países mais fracos através da geração de um sistema global de preços. A desconexão implica, em termos econômicos, a tentativa de gerar nos países e regiões desconectados, sistemas de preços internos diferentes dos globais, de tal forma que um modo diferente de acumulação de riqueza seja gerado. Isso significa recuperar o uso de instrumentos de regulação estatal e a possibilidade de distribuir o excedente econômico contemplando a integração do tecido social.In this seminar we present the theory of the disconnection/dislinking of Samir Amin and show its explanatory capacity in the analysis applied to the governments of Juan Domingo Perón (1946-1955) and those of Néstor Kirchner and Cristina Fernández (2003-2015). Samir Amin provides a valuable theoretical framework for understanding the functioning of the global capitalist system based on his theory of the five monopolies in dispute: natural resources, financial resources, scientific and technical research, weapons of mass destruction and media. According to the author, strategic control over these resources allows the central countries, through their transnational corporations, to seize the economic surpluses of the weakest countries through the generation of a global price system. The disconnection/dislinking implies in economic terms the attempt to generate in the disconnected countries and regions, internal price systems different from the global ones, in such a way that a different mode of accumulation of wealth is generated. This means recovering the use of state regulation instruments and the possibility of distributing the economic surplus contemplating the integration of the social fabric.Seminario de posgrado dictado en la Facultad de Trabajo Social de la Universidad Nacional de La Plata en el año 2018.Facultad de Trabajo Socia

Effect of Oxalic Acid on Control of Post-harvest Browning of Litchi (Litchi chinensis L.)
No full textPost-harvest browning of litchi is a common phenomenon that occurs due to enzymatic and non-enzymatic reactions. Enzymatic browning is primarily caused by polyphenol oxidase (PPO) activity, leading to the formation of brown pigments. Non-enzymatic browning is caused by the Maillard reaction between reducing sugars and amino acids. Factors such as temperature, humidity, and mechanical damage can accelerate browning. Proper handling, storage, and the use of antioxidants can help minimize post-harvest browning, extending the shelf life and maintaining the visual appeal of litchi fruits. The present investigation was laid out in the post-harvest laboratory of horticulture department, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during the year 2022-2023. The experiment was laid out in the CRBD with 8 treatments and 3 replications. Litchi fruit, Cv. Purvi (about 80%- matured stage), were harvest from a Local market Prayagraj, fruit was selected for uniformity of size and colour, and blemished and diseased fruit were discarded. The selected fruit were dipped in different oxalic acid concentration solution (0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5 and 4.0mM) and Bavistin (0.05mg) as the control) for 10 mint 4 h of harvest, and then air dried. Each 10 fruit of the treated fruit was packed into a plastic punnet and wrapped with a 0.2-mm polyethylene bag, and then stored in an ambient condition. Post-harvest storage studies revealed that under ambient and refrigerated storage conditions T8 Oxalic acid (4.0mM) + Bavistin (0.05%) treatment showed slower rate of reduction on fruit length (cm) and fruit weight (g), browning (%) were significantly affected by treatments. There was significant effect of treatments on chemical parameters like pH, TSS (0Brix), acidity (%), ascorbic acid (mg100g), reducing sugar under ambient and refrigerated storage at different day’s intervals
