Abstract -- In this study, the peels of waste agricultural products (banana, orange, potato) used as biosorbent in order to remove textile dyes from aquatic solutions. Biosorption of the commonly used textile dye such as Acid Red P-2BX (AR) was investigated by the peels of different agricultural products. The waste peels of banana, orange and potato were prepared as dried and ash biosorbent. The effects of pH, biosorbent type, dye concentration, biosorbent dosage and temperature on dye biosorption were tested at batch scale level. The best removal of dye was performed by the banana peel. Biosorption by dried banana peel for AR dye was found to be 73.58% at optimum conditions. It was concluded that dried banana peels were effectively used in the treatment of textile dye- contaminated water.

The banana is one of the most commonly consumed fruits in Sri Lanka; after the fruit is harvested, the pseudostem is thrown down as waste. The banana pseudostem is a good source of natural fiber. The purpose of this project is to investigate the effects of banana fiber extraction, examine treatment parameters on fiber fineness and establish suitable methods to reduce the fineness that enable banana fibers to be used as textile materials. Ten popular Sri Lankan varieties of banana pseudostem were selected for this study. From the mechanically extracted banana fiber of these 10 varieties, Ambun (genome AAA) was selected for further analysis because it had the lowest fiber fineness. Four layers from the pseudostem of Ambun were extracted and put through a fineness and single fiber strength test. Scanning electron microscopy and fiber linear density were used to observe and determine the fineness of the enzyme and chemical treated banana fiber. The mechanical strength of the treated banana fibers was obtained by using a universal tensile tester machine. The test result showed the second and the third layers of the pseudostem to be the finest. The mechanically extracted fiber of the second and third layers of the pseudostem were put through an enzyme and chemical treatment. Results showed enzyme and chemical combined treated fibers to be the finest, with a reduced diameter from 168.4 µm to 48.8 µm, which is about 71% reduction compared to mechanical extraction.

Textile waste is produced in the starch process, a starch removal process, coloring, and printing. The use of banana peel (Musa Paradisiaca) was an alternative that was being developed as an absorbent to remove the color content and metal ions in textile waste. The purpose of this study was to analyze the workings and effectiveness of heavy metal adsorption and textile dyes with banana peel waste. Banana peel particles that were ready to be used as adsorbents were characterized using Scanning Electron Microscopy (SEM) to obtain particle morphology. Absorbance curve of Cu2+ dan Cr6+ can be obtained using spectrophotometric UV-Vis analysis with a wavelength of 635 nm for copper (Cu) and 469 nm for chromium (Cr). The activated carbon of banana peel was applied to 50 ml industrial waste solution and observed changes in absorbance for 120 minutes. The activated carbon was directly in contact with the solution of metal ions but the adsorption power was still not seen effectively so that the Atomic Absorption Spectroscopy (AAS) test was performed. The results of AAS analysis, namely activated carbon can reduce copper and chromium ion content respectively by 55.5% and 61%. If this activated carbon was used as an adsorbent for dyes in textile waste, the average absorption capacity of dye ion was 12.21% during the contact time of adsorption 120 minutes.

To show that banana inflorescence has effective adsorbent for the adsorption of dyes (congo red, remazol yellow, remazol black and methylene blue) from textile dyes waste and also to detrmine the optimum conditions of variety of pH (4-10), temperature (30°C-90°C), and contact time (15-105 minute) on the percentage adsorption capacity of banana inflorescence. Textile dyes waste and their degradation products such as aromatic amines are highhly carcinogenic. Adsorption-fluidization is a new technology for treatment of waste water containing different types of dyes. Adsorption-fluidization process is adopted for adsorption of dyes from the textile dyes waste using banana inflorescence in treated form and were analysed by Utraviolet-Visible Spectroscopy. The results showed that the optimum condition from adsorption process of Congo Red dye by banana inflorescence was reached at pH 5 (1.78%), temperature 60°C (1.51%) and 45 minute contact time (1.63%). While Remazol Yellow dye optimum at pH 9 (4.29%), temperature 50°C (4.65%) and 75 min (1.83%). Another dye, Methylene Blue showed the optimum condition at pH 9 (0.36%), temperature 40°C (0.22%) and 45 min contact time of adsorption (0.43%). The last, Remazol Black dye was reached at pH 5 (0.56%), temperature 40°C (0.56%) and 75 min contact time (0.56%).

Full textAbstract:
The use of natural fibres allows reducing environmental impact, due to their natural renewable origin and the lower energy needed for their production and processing. This work presents the mechanical characterization of a newly developed technical textile, with banana fibre treated by enzymes, comparing experimental results with numerical simulation based on the definition of the unit cell at micromechanical level. The experimental test shows that the composite with the fabric of banana fibre presents worse mechanical behaviour than the one with commercial flax fibre. The presence of wool, necessary for producing the yarn, reduces the mechanical properties of the banana textile. The numerical simulation had an acceptable error compared with the experimental results, with a global average error of 9%, showing that the predictive modelling based on the multiscale method is suitable for the design process of this kind of composite.

Full textAbstract:
Disposal of reactive dye contaminants in surface waters causes serious health risks to the aquatic living bodies and populations adjacent to the polluted water sources. This study investigated the applicability of banana peels to remediate water contamination with reactive dyes used in the textile industry. A set of batch experiments was conducted using a standard dye solution to determine optimum adsorption parameters, and these parameters were used for the removal of dyes from actual wastewater. Fitting experimental data into the isotherm and kinetic models suggested monolayer dye adsorption with chemisorption rate-limiting step. The maximum adsorption found from modeling results was 28.8 mg/g. Fourier transformed infrared (FTIR) spectra revealed the existence of hydroxyl, amine and carboxylic groups, contributing to high adsorption of dye molecules onto the adsorbent surface. About 93% of the dyes from the standard solution were removed at optimum conditions (pH—7.0, initial dye concentration—100 mg/L, contact time—60 min, and adsorbent dose—0.5 g) while this value was 84.2% for industrial textile wastewater. This difference was mainly attributed to the composition difference between the solutions. However, the removal efficiency for actual wastewater is still significant, indicating the high potentiality of banana peel removing dyes from textile effluent. Furthermore, desorption studies showed about 95% of banana peel can be recovered with simple acid-base treatment.

The global textile business is now gearing towards greener alternatives to combat pollution and avoid synthetics in production. Ironically, there is an increased awareness among consumers on the quality of the product and choices they make in their shopping. The natural and synthetic fibres have set limitations, which has made manufacturers look out for other alternative fibres. Bamboo, banana, milk, and corn are experimented for its commercial capabilities to perform as a textile material. To add on to the list, orange, the popular, and the most preferred fruit are known for its refreshing flavour. The peels after consumption/ processing of the fruit are discarded in the landfill, which is an organic waste with immense potential. This paper details the successful brand ‘Orange fibre’, its journey from scratch, and the properties of textiles made from processing orange peel waste. The current areas of research have also been covered in a brief way, to invite more scholars to create solutions for the hitherto pollution orange peel waste.

Cellulose acetate hollow fiber membrane from banana stem fibers coated by TiO2 (CAHFMT) was prepared and characterized as an alternative material for degradation of waste textile dye. Its applicability was demonstrated by mechanical properties, FTIR, SEM, thermal resistance, performance, and degradation efficiency. Cellulose acetate (CA) was synthesized from banana stem fibers by swelling stage, acetylation reaction, and hydrolysis reaction. CA was modified using TiO2 of various concentrations. CAHFMT with 22 % w/v dope concentration has the optimum mechanical properties (stress, strain and Young’s modulus), as well as hydrophilic properties. The performances of CAHFMT with Congo red were determined. The SEM results showed that the membrane had rigid pores. Moreover, this research stated that CAHFMT could be a solution to overcome economical and effective problems.

Mestrado em MarketingEste projeto consiste na elaboração de um Plano de Marketing a iniciar em 2016 para a loja Banana Chiclete. O estabelecimento concilia a venda de artigos têxteis e acessórios em 2ª mão com o serviço de cafetaria na zona histórica da cidade de Coimbra. Com este Plano, pretendeu-se efetuar o diagnóstico empresarial da loja, com enfoque na aferição da qualidade do serviço na perceção do cliente, determinação dos objetivos e estratégias genéricas de Marketing e delineação das táticas de Marketing Mix apropriadas. A Action Research foi a estratégia de investigação adotada. Nesta, o trabalho colaborativo entre o investigador e os membros da organização facilita o diagnóstico da situação organizacional para a analisar posteriormente e agilizar as restantes etapas do Plano. A aferição da qualidade do serviço é um fator-chave na perceção dos clientes (Zeithaml, Bitner, & Gremler, 2005), pelo que,com base no instrumento SERVPERF, se aplicou um inquérito por questionário aos clientes do estabelecimento. Deste projeto conclui-se que o recente interesse que desencadeou o crescimento deste mercado nos últimos anos, em Portugal, contrasta com a falta de dados do perfil sociodemográfico deste consumidor, a par da inexistência de dados de mercado deste setor. Além disso, é necessário ter em conta a importância do digital, tanto na comunicação destes estabelecimentos, assim como na venda de artigos neste meio - e-commerce. É necessária, também, a existência de serviços alternativos, a par de uma renovação constante do stock existente e criação de eventos que cativem os clientes a visitar o estabelecimento mais vezes.
This project consists in developing a marketing plan for the year 2016 for a second hand store named Banana Chiclete. They combine the sale of second hand garments and accessories with a cafeteria service, set in the historic city of Coimbra. The aim was to make the diagnosis of the store?s business, focusing on measuring the customers? perceived service quality, setting of goals and generic marketing strategies and definition of appropriate marketing mix tactics. Action Research was the adopted research strategy where the collaborative work between the researcher and the members of the staff allows the diagnosis of organizational situation for later review and streamlining of the remaining steps of the Plan. Gauging the quality of service is a key factor in customer perception (Zeithaml, Bitner, & Gremler, 2005) and, based on the SERVPERF instrument, administered a questionnaire to the store customers. This project concludes that the recent growing interest on this market in recent years, in Portugal, contrasts with the lack of sociodemographic this consumer profile data, along with the absence of market data in this sector. These facts make it difficult or even prevents a more accurate analysis. Moreover, it is necessary to take into vogue the importance of digital, especially in the communication of these establishments, as well as the sale of articles in this medium - e-commerce. Moreover, existence of alternative services, along with a constant renewal of the existing stock and creating events that captivate customers to visit more often establishment.

In this work was investigated the potential of banana tree pseudostem, an agricultural waste used in natura (BIN) and treated with methanol (BTM), as adsorbents in removal of textile dyes Violet Brilliant Remazol and Turquoise Remazol from aqueous solution. The adsorbents were characterized by infrared spectroscopy, 13C nuclear magnetic resonance, elemental analysis, thermogravimetry and X-ray diffraction. The zero point of charge (pHzpc) the materials were 5.1 (BIN) and 4.3 (BTM). The pH study showed that the maximum amount adsorbed occurred in pH's 1.0 and 2.0. The kinetics was performed at pH 2.0, 25°C and was evaluated at concentrations of 250 and 1000 mg.L-1. The contact times required for both adsorbents reach equilibrium in the two concentrations studied were 120 and 300 minutes for the dyes Violet and Turquoise, respectively. The kinetics sorption data were fitted to pseudo-first order, second order, and intraparticle diffusion models and the equilibrium data were fitted to the Langmuir and the Freundlich isotherm models. Taking into account correlation coefficients, the data were best fitted to the second order kinetic model (R2> 0.999). The intraparticle diffusion model is also involved in the mechanism of adsorption, which showed that the adsorption takes place in three steps. With the exception of Turquoise Remazol by BIN, all other systems were best fitted to Freundlich isotherms. The adsorption isotherms were evaluated at four different temperatures (10, 25, 40 and 55 °C) by varying the concentration of the dye from 100 to 1000 mg.L-1 in the best conditions of pH and equilibrium time. The thermodynamic parameters indicated that the process is endothermic (Turquoise) and exothermic (Violet). The spontaneity of the sorption processes for all dyes was also confirmed by the favorable negative values of Gibbs free energy and by positive entropic data. Desorption of dyes was carried out in alkaline (pH 8.0), being recovered 44% (BIN) and 38% (BTM) for the Violet Brilliant Remazol and 34% (BIN) and 21% (BTM) for the dye Turquoise Remazol. This value suggests the application of this biopolymer as a favorable agent for textile dyes removal from a given system.
Neste trabalho foi investigado o potencial do pseudocaule de bananeira, um resíduo agrícola utilizado in natura (BIN) e tratado com metanol (BTM), como adsorventes na remoção dos corantes têxteis Violeta brilhante remazol e Turquesa remazol de soluções aquosa. Os adsorventes foram caracterizados por espectroscopia no infravermelho, ressonância magnética nuclear de 13C, análise elementar, termogravimetria e difratometria de raios X. O ponto de carga zero (pHzpc) dos materiais foram 5,1 (BIN ) e 4,3 (BTM). O estudo do pH mostrou que a quantidade máxima adsorvida ocorreu nos pH s 1,0 e 2,0. As cinéticas foram realizadas em pH 2,0, temperatura de 25°C e foram avaliados nas concentrações de 250 e 1000 mg.L-1. Os tempos de contato necessários para ambos os adsorventes atingirem o equilíbrio, nas duas concentrações estudadas foram 120 e 300 minutos para os corantes Violeta e Turquesa, respectivamente. Os dados cinético de adsorção foram ajustados aos modelos de pseudo-primeira ordem, segunda ordem e difusão intrapartícula e os dados de equilíbrio foram ajustados aos modelos de isoterma de Langmuir e Freundlich. Levando em consideração os coeficientes de correlação, os dados cinéticos foram melhor ajustados ao modelo de segunda ordem (R2 > 0,999). O modelo de difusão intrapartícula também está envolvido no mecanismo de adsorção, o qual mostrou que a adsorção acontece em três etapas. Com exceção do Turquesa remazol pelo BIN, todos os outros sistemas foram melhor representados pela isoterma de Freundlich. As isotermas de adsorção foram avaliadas em quatro temperaturas diferentes (10, 25, 40 e 55 ºC) variando-se a concentração do corante de 100 a 1000 mg.L-1 nas melhores condições de pH e tempo de equilíbrio. Os parâmetros termodinâmicos indicaram que o processo é endotérmico (Turquesa), exotérmico (Violeta). A espontaneidade dos processos de sorção de todos os corantes também foi confirmada pelos valores negativos da energia livre de Gibbs e pelos dados positivos de entropia. A dessorção dos corantes foi realizada em meio alcalino (pH 8,0), sendo recuperado 44% (BIN) e 38% (BTM) para Violeta brilhante remazol e 34% (BIN) e 21% (BTM) pra o corante Turquesa remazol. Este valor sugere a aplicação deste biopolímero como agente favorável para a remoção de corantes de efluentes têxteis a partir de um determinado sistema.

Resumo: Este trabalho estudou o processo de obtenção de banana nanica crocante através da secagem a altas temperaturas e curto período de tempo (HTST - High Temperature and Short Time). O processo consistiu de um pré-tratamento a 70°C durante 5 minutos, de uma etapa à alta temperatura (130°C, 1400C e 150°C) e curto tempo (9, 12 e 15 minutos) e de uma etapa à temperatura de 70°C até atividade de água em torno de 0,320. De modo a verificar a influência da etapa HTST no processo, montou-se um planejamento experimental fatorial 22 com 3 pontos centrais, cujas respostas do processo foram o grau de reidratação, o parâmetro k do modelo de Lewis (para a etapa HTST, 70°C e secagem completa) e a crocância, avaliada por medidas sensoriais e instrumentais de textura. O planejamento experimental resultou numa matriz com as condições de ensaios de 130°C-9min, 130°C-15min, 150°C-9min, 150°C-15min e três pontos centrais a 140°C-12min. Banana crocante foi obtida com as condições de 140°C-12min e 150°C-15min de etapa HTST, com atividade de água de 0,345 e 0,363, respectivamente. Os resultados mostram que o melhor grau de reidratação ocorreu para os tempos de 10 e 5 minutos e que existe uma significativa relação entre a crocância e a temperatura da fase HTST. Não foi possível encontrar um ajuste adequado ao parâmetro k do modelo de Lewis para a etapa HTST e a 70°C, porque as umidades iniciais eram diferentes e promoveram grande diferença nos valores desse parâmetro. Adicionalmente, caracterizou-se a crocância de frutas comerciais liofilizadas e determinou-se a aw. Os resultados obtidos para a banana comercial liofilizada foram comparados com os da banana desidratada obtida neste estudo. As medidas instrumentais e sensoriais mostraram que ambas foram consideradas crocantes
Abstract: We present here a study about producing crispy banana using a HTST (High Temperature Short Time) process. The process involves pretreatment of the fruit during 5 minutes at 70°C, a dry HTST stage (130, 140 and 150°C and 9, 12 and 15 minutes) and, finally, a dry stage at 70°C until the water activity (aw) is near 0,300. In order to evaluate the HTST stage in the process, we used a factorial 22 design with 3 center points. The results produced by this analysis were the rehydratation degree, the model parameter of Lewis k (considering either the complete process, the HTST stage and the dry stage at 70°C). Also, crispness was analyzed according to sensorial and instrumental measurements. This process generated a matrix containing the results of several trial runs for the following settings: 130°C-9min, 130°C-15min, 150°C-9min, 150°C-15min and 3 center points at 140°C-12min. Crispy banana was obtained only with 140°C-12min and 150°C15min, where aw = 0,345 and aw = 0,363, respectively. The results show that the best rehydration degree occurs for 10 and 5 minutes. Also, there exists a relationship between the crispness (sensorial and instrumental) and the HTST stage. However, it was not possible to find a suitable value to the Lewis Model parameter k to HTST and 70°C dry stages. This is because the initial moisture of the fruits was not the same for all tests, which produced different values for k. In addition, we evaluated the crispness of commercial freeze-dried fruits and the water activity value. Finally, we compared measurements of the commercial banana with the dried banana obtained in this work. Both were considered crispy

CAPES
Banana is a perishable fruit, as it ripens fast and cannot be adequately preserved by the cold, resulting in large post-harvest losses. The application of preservation techniques, such as osmotic dehydration, reduces losses of the commodity in post-harvest stage, extend its shelf-life, while not severely affecting its nutritional values, and functional and sensorial properties, which makes it at processing alternative for the fruit. The aim of this study is to evaluate the kinetics of osmotic dehydration, as well as the quality of the osmotically dehydrated samples in terms of color, texture, and antioxidant capacity, using fructo-oligosaccharide, corn syrup and the mixture of both, under different temperatures. To determine the kinetics, the fruit, cut in cubes, was dehydrated in different solutions, under temperatures of 40, 50 and 60 ? C. The kinetics of water loss (WL) and solid gain (SG) were evalueted at 30, 60, 90, 120, 180, 240, 360, 720 to 1440 minutes. The analysis of variance was used to verify the effect of each solution and temperature on kinetics. The kinetic parameters were modeled based on the equations of Peleg, Page modified and Barbosa Junior et al. using non-linear regression. The time to reduce the dehydration rate or penetration to one third of its initial values (t(1/3)) and the process average time (t(average)) were obtained on the Barbosa Junior et al. model The quality of the samples was accessed at these two times, in different solutions under different temperatures. For such, the variation of the instrumental parameters of color, antioxidant capacity (FRAP, DPPH and total phenolic content), and texture (axial compression tests) of samples, in nature as well as processed, were verified. The WL was not affected significantly by the type of solute used, however, the temperature presented significant influence over these parameters (p < 0.05). The experimental data for the WL was adequately adjusted to the Peleg and Page modified models with coefficients of determination (R?) superior than 0.98, mean relative error (E) inferior than 6.5% in all treatments. The water loss content values varied from 15.75 to 28.79% at time t(1/3), while for the time t(averege) 15.75 to 30.27% between treatments. The process of osmotic dehydration had affect on the quality of the final product, showing significant differences between the fruits in natura and processed state, in terms of color, antioxidant capacity and texture of the samples.
A banana ? um fruto perec?vel, pois sofre r?pido amadurecimento, n?o pode ser devidamente conservado pelo frio, sendo acometido por grandes perdas p?s-colheita. A utiliza??o de t?cnicas de conserva??o, como a desidrata??o osm?tica, reduz as perdas p?s-colheita, estende a validade comercial, n?o acarreta em severas altera??es nas caracter?sticas nutricionais, funcionais e sensoriais e mostra-se como uma alternativa de processamento para este fruto. O objetivo desde trabalho foi avaliar a cin?tica da desidrata??o osm?tica, bem como, a qualidade das amostras desidratadas osmoticamente em termos de cor, textura e capacidade antioxidante, utilizando fruto-oligossacar?deo, xarope de milho e a mistura de ambos, em diferentes temperaturas. Para determina??o da cin?tica, a banana, cortada em cubos foi desidratada nas diferentes solu??es, sob as temperaturas de 40, 50 e 60 ?C. As Cin?ticas de Perda de ?gua (PA) e ganho de s?lidos (GS) foram avaliadas nos tempos 30, 60, 90, 120, 180, 240, 360, 720 e 1440 minutos. A an?lise de vari?ncia foi usada, a fim de verificar o efeito do tipo de soluto e da temperatura na cin?tica. Os par?metros cin?ticos foram modelados de acordo com a equa??o Peleg, Page modificado e Barbosa J?nior et al. utilizando regress?o n?o-linear. A partir do modelo de Barbosa J?nior et al., obteve-se o tempo para reduzir a taxa de desidrata??o ou impregan??o a um ter?o de seus valores iniciais (t(1/3)) e o tempo m?dio de processo (t(m?dio)). A qualidade das amostras foi avaliada nestes dois tempos, nos diferentes solutos e temperaturas. Para tal, foram verificadas a varia??o dos par?metros instrumentais de cor, a capacidade antioxidante (FRAP, DPPH e teor de fen?licos totais) e a textura (ensaios de compress?o axial) das amostras in natura e processadas. A PA n?o foi afetada significamente pelo tipo de soluto empregado, no entanto, a temperatura apresentou influ?ncia significativa neste par?metro (p < 0,05). Os dados experimentais para a PA se ajustaram adequadamente ao modelo de Peleg e Page modificado e obtiveram-se coeficientes de determina??o (R?) maiores do que 0,98, desvio relativos m?dios (E) inferiores a 6,5% em todos os tratamentos. O modelo do tempo de n-redu??o da taxa de desidrata??o se mostrou uma boa alternativa na defini??o do tempo de processamento das amostras submetidas ? desidrata??o osm?tica. Os valores de perda de ?gua variaram de 15,70 a 28,79% no tempo t(1/3), enquanto que para o tempo de t(m?dio) de 15,75 a 30,27% entre os tratamentos. O processo de desidrata??o osm?tica influenciou na qualidade final dos produtos, apresentando diferen?as significativas entre a fruta in natura e a processada para varia??o dos par?metros de cor, a capacidade antioxidante e a textura das amostras in natura e processadas.

Previous issue date: 2009-09-28This dissertation presents the development of a computer vision system for bananas (Musa sapientum) analysis in post-harvest stage based on digital image processing techniques. The development used considerations about image acquisition, pre-processing, identification based on texture, percentage of brown spots and injuries on the fruits and classification of its maturity levels. The validation has been developed considering geometric patterns generated in laboratory, as well as real fruits. With the texture map it was possible to identify the existence of brown spots or injuries in a specific region of the images. The assessment of the level of maturation was performed considering both human observers and the computer vision system. The average of identification level of maturity was equal to 50% for human observers and 100% for computer vision. The results show identification rates of 80.40% for brown spots on the single image of banana, 97.70% for brown spots on the images of bundle of bananas, 97.80% for injuries for the set of single image of banana, and 75.30% for hand injuries considering the images of bundle of bananas. Besides, the method presents application for quality assessing of fruits in the post-harvest procedures.
Este trabalho apresenta o desenvolvimento de um sistema de visão computacional para análise de bananas (Musa sapientum), em estágio de pós-colheita, utilizando técnicas de processamento digital de imagens. Para o desenvolvimento foram consideradas as etapas de aquisição das imagens, pré-processamento, identificação baseada em textura, classificação em níveis de maturação e a obtenção do percentual de manchas marrons e injúrias. A validação foi desenvolvida considerando padrões geométricos gerados em laboratório, bem como considerando frutas reais. A obtenção do mapa de textura viabilizou a identificação da existência de manchas marrons ou injúrias em uma região da imagem. A avaliação método de classificação em nível de maturação foi realizada considerando os resultados obtidos com observadores humanos e visão computacional. A média da taxa de acerto dos observadores foi de 50% e a taxa de acerto da visão computacional foi de 100%. Além disso, os resultados da análise de manchas marrons e injúrias indicam uma taxa de acerto de 80,40% para manchas marrons em imagem de banana individual, 97,70% para manchas marrons em imagem de penca de bananas, 97,80% para injúrias em imagem de banana individual e 75,30% para injúrias em imagem de pencas. Adicionalmente, o desempenho global do sistema motiva a aplicação desta metodologia para avaliação da qualidade dos frutos no pós-colheita de bananas.

Neste trabalho, foram desenvolvidas antenas têxteis de micro-ondas para aplicação em sistemas vestíveis, operando nas bandas ISM de 2,45 GHz e 5,8 GHz. Foram compiladas informações sobre o estado da arte em antenas têxteis, sendo realizado um estudo sobre antenas planares de micro-ondas e técnicas de alimentação das mesmas. Foi feita uma prospecção dos processos de fabricação de antenas têxteis de micro-ondas, definindo-se o processo e materiais têxteis usados na construção das antenas desenvolvidas. Procedeu-se à caracterização do tecido usado como substrato das antenas determinando-se suas características eletromagnéticas, utilizadas no projeto das antenas. Foram desenvolvidas antenas de microfita com plaqueta retangular e alimentação por sonda coaxial, para banda ISM de 2,45 GHz. Investigou-se o efeito da espessura do substrato da antena, tendo-se obtido experimentalmente larguras de banda de 4,8% e 6,0% para substratos com 0,7 mm e 1,4 mm de espessura, respectivamente. Foi proposta uma antena de microfita alimentada via acoplamento por proximidade que integra um transformador de um quarto de comprimento de onda ao circuito de alimentação, resultando em alargamento de banda da antena. Essa configuração foi utilizada no projeto de quatro antenas, que demonstraram experimentalmente larguras de banda de 11,2%, 13,4%, 17,0% e 24,0%. Uma configuração de antena têxtil empregando cavidade de um quarto de modo foi proposta para operação em banda dupla, sendo a tecnologia de guia de ondas integrado ao substrato - SIW, empregada em sua fabricação. Foi desenvolvido um procedimento de projeto para essa antena, o qual foi aplicado ao projeto de uma antena de banda dupla para as faixas ISM e 2,45 GHz e 5,8 GHz. Os resultados experimentais demostraram operação em banda dupla, com largura da banda inferior de 9,3%, e largura da banda superior de 9,2%. A antena de cavidade de quarto de modo apresentou as vantagens de maior ganho e menores dimensões relativamente às antenas têxteis de microfita desenvolvidas. De forma geral, os resultados experimentais dos protótipos construídos apresentaram boa concordância com os resultados fornecidos por simulação, demonstrando que as configurações de antenas propostas atenderam a seus objetivos, e a efetividade dos procedimentos de projeto adotado.In this work, textile microwave antennas for use in wearable systems operating at 2.45 GHz and 5.8 GHz ISM bands were developed. Information on the state of art in textile antennas were compiled, and a study on microwave planar antennas and feeding techniques was performed. Processes for manufacturing textile microwave antennas were presented, and the fabrication process and textile materials used in this work were defined. The electromagnetic characteristics of the fabric used as antenna substrate were experimentally obtained, and used in the antenna design. Microstrip antennas using rectangular patch and coaxial probe feed were designed to operate at the 2.45 GHz ISM band. The effect of the antenna substrate thickness on the antenna characteristics was investigated, and experimental bandwidths of 4,8% and 6% were demonstrated for antennas with 0.7 mm and 1.4 mm thick substrates, respectively. A microstrip antenna fed by proximity coupling, including a quarter wavelength transformer at the feeding circuit, was proposed, resulting in the widening of the antenna bandwidth. This configuration was used to design four antennas, which experimentally demonstrated bandwidths of 11.2%, 13.4%, 17.0% and 24.0%. A textile antenna configuration employing a fourth mode cavity was proposed for dual band operation. Substrate integrated waveguide technology - SIW, was used for the antenna manufacturing. A design procedure was developed for this antenna, which has been applied to the design of a dual band antenna for the 2.45 GHz and 5.8 GHz ISM bands. The experimental results of this antenna demonstrated dual band operation, with 9.3% bandwidth at the lower band and 9.2% bandwidth at the higher band. The quarter mode cavity antenna presented the advantages of increased gain and smaller area than the designed textile microstrip antennas. In general, the experimental results of the fabricated prototypes exhibited good agreement with the results provided by simulation, demonstrating that the textile antenna configurations proposed met their expected performance and validating the design procedures adopted.

The embroidery of the Banjara people makes an important part of Indian culture, The Banjara are a previously migrating non-hinduistic ethnic, today mostly settled and merging with the hinduistic population which represents the majority. We still have very scarce information about this distinctive textile production. This theses is based on mostly Indian studies, as well as on field-work which was carried out in fourteen Banjara communities living in two Indian states, Maharashtra and Karnataka. Another source of information were several collections of Banjara textile in important European museums and a collection of more than 550items in the Czech Republic. The theses focuses on five subjects: 1. The typology of the fourty most common and traditional types of textile pieces made by Banjara women, 2. The description of the material and embroidery techniques, 3. The attempt of the iconography analysis of the Banjara embroidery, 4. The provenience of the Banjara traditional pieces, and 5. The description of the state of art of the mbroidery which still exists in the present day Banjara communities. Vast photodocumentation made during the field-work is included in the theses and a catalogue of typical examples from studied collections. A side product has evolved during the study of the Indian literature - an...

Full textAbstract:
Sustainable agriculture can be defined in many different ways. In industrial nations, sustainable agriculture means improving energy use efficiency, reducing environmental pollution, and increasing and sustaining profitability. For millions of small-holder farmers throughout the tropics, sustainable agriculture means providing basic food needs for the farming family, improving the farmer’s ability to replenish soil nutrients and control soil degradation, and optimizing crop yield per unit area of land. Soil utilization for agricultural production in the tropics during the past two centuries, to a large extent, has been influenced by the technological and economic changes in temperate regions. Research and development for agriculture during the colonial era were mainly focused on the needs of industrial nations, while the production of food crops for the indigenous inhabitants was largely left in the hands of the traditional slash-and-burn cultivators. Large and small cash crop plantations were developed on fertile, high-base-status allophanic and oxidic soils for coffee, cocoa, banana, and sugarcane production throughout the humid and subhumid tropics. Cotton was cultivated on smectitic soils and high-base-status kaolinitic soils in the subhumid and semiarid regions of Africa for the textile industries in temperate regions. In tropical America, cattle ranching, a production system introduced by European immigrants, still occupies most of the fertile flat land today, while food grains are usually cultivated on less fertile land or in shallow soils on steep slopes. In tropical Africa and Latin America, a wide range of food crops, such as maize and beans, potato, cowpea, sorghum, millet, cassava, and yam are mostly produced under the traditional slash-and-burn system of cultivation on less fertile kaolinitic soils. In tropical Asia, the indigenous intensive rice-based agriculture on wet smectitic soil has been practiced over many centuries and has been able to meet the basic food needs for the increasing population in the region. Generally, upland food crop production in the tropics has not kept pace with human population growth in the tropics during the past century. It was not until the 1950s and 1960s, following the independence of many nations in tropical Asia and Africa, that more attention was given to the research and development of food crop production.

Full textAbstract:
One term that has acquired a particular air of consumer suspicion in recent years is “processed food. ” Processing is seen as being something that is used to make food less fresh, less natural, and so more suspicious. However, even though we say we don’t want processed food, every food product, before it gets to your mouth, has been subjected to some form of processing and treatment that has a scientific basis. Even washing an apple, chilling sushi, or peeling a banana are forms of food processing, while the bag of salad we buy in a shop or market isn’t full of air as we might expect. All of these phenomena I will discuss in coming chapters. Before dealing with the science of food processing, it is worth discussing what exactly that highly loaded term means. To a food scientist (well, me anyway), food processing means subjecting foods or raw materials to external forces designed to cause a desirable change in the food, typically in terms of its safety and stability, and also in many cases its flavor, texture, and color. In many cases, the primary target of food processing is the resident population of contaminating microorganisms that, if not dealt with, might otherwise cause the food to spoil, or else spoil the day of consumers who finds themselves with a range of symptoms of food poisoning, up to the most lethal. The force most commonly applied in processing is temperature, whether low (refrigeration), very low (freezing), high (for example, pasteurization or cooking), or very high (canning or sterilization). Temperature is indeed probably the key physical variable of significance to food, as almost everything that happens in and to food is influenced by temperature, and most changes take place optimally in a relatively narrow band around body temperature (37 °C). If temperature is pictured as a line scale, the zone of greatest danger and likelihood is centered around that point, but food processors look far below and above that zone and have come to understand how we can work around the optimum temperatures for various reactions and biological changes in order to make our food safer and more stable.

Puffing is an attractive alternative for the production of healthy crisp snacks without frying. Although image analysis has been used in some prior studies to evaluate puffing, such an evaluation was made only in one or two dimensions, which is inadequate when a sample deforms in three dimensions. In this study, use of combined hot-air and microwave drying to dry and puff banana slices was first evaluated. Algorithms were then developed to characterize the changes in the appearance of puffed banana slices. Various image-based parameters, both in two and three dimensions were assessed and used to monitor the puffing. Keywords: Deformation; Puffing; Imge analysis; Physical properties; Surface texture
