DOS CABIDES DE EMPREGO AOS CABIDES DO CONHECIMENTO: UM CASO DE PARCERIA ENTRE O INSTITUTO GENERAL MOTORS E A ESCOLAMUNICIPAL DE ENSINO PROFª. ALCINA DANTAS FEIJÃO NO DESENVOLVIMENTO DA RESPONSABILIDADE SOCIAL EMPRESARIAL

O Brasil, até poucos anos atrás, não via em sua agenda de prioridades a educação como foco principal para o crescimento econômico, talvez por não acreditar que com a estabilidade da moeda, abertura da economia e outros fatores necessitassem de pessoal qualificado para poder manter a capacidade produtiva. Assim, o país tenta corrigir esta situação investindo em educação, incorporando novas tecnologias no processo produtivo, necessitando de uma força de trabalho hábil para aprender e desenvolver as novas técnicas. Atualmente o Brasil mantém um dos menores índices de desemprego, no entanto, muitas empresas sofrem com o apagão da qualificação, necessitando realizar treinamentos e por consequência aumento em seus custos. As empresas tentam driblar a falta de pessoal qualificado investindo nos programas de estágio e trainee, realizando contratações de profissionais estrangeiros, criando universidades corporativas, e em alguns casos, as empresas estreitam seus laços junto às redes de ensino, a fim de preparar jovens para o domínio de novas tecnologias, associado ao aprimoramento em sua área de atuação, evitando assim o desequilíbrio entre teoria e prática . As organizações empresariais conscientes de seu papel começam a compreender que a prosperidade tão almejada não se traduz por faturamentos vultosos ou simplesmente pela quantidade de produtos vendidos. Estas despertam para a criação e adaptação de empresas-cidadãs que por meio de suas ações sociais, buscam desenvolver atividades solidárias. Neste contexto, o presente trabalho tem como objetivo geral analisar a Responsabilidade Social Empresarial sob a ótica de parcerias com escolas (parceria entre a General Motors do Brasil, por meio de seu braço social - o Instituto General Motors e a Escola Municipal de Ensino Profª. Alcina Dantas Feijão da Cidade de São Caetano do Sul). A parceria se concretiza, por meio do Programa Jovens Empreendedores ou Fábrica de Cabides . O intuito do Programa é despertar o espírito empreendedor nos estudantes e incentivar a formação de futuros empresários. Com os objetivos específicos determinou-se: a) estudar parcerias entre empresas e escolas no desenvolvimento da RSE; b) entender os motivos que levaram a empresa e a escola a concretizar a parceria e suas expectativas; c) identificar possíveis alterações ocorridas na escola, atribuídas ao processo de parceria. A partir destes objetivos, o procedimento metodológico foi orientado pelo método de estudo de caso, objetivando uma pesquisa mais voltada para abordagem qualitativa, levantando-se referenciais teóricos, bem como, procedimentos de análise de dados por meio de questionário, observação direta e artefatos físicos. A análise compreensiva dos dados foi realizada a partir de dois núcleos temáticos: importância da parceria e mercado de trabalho. Os resultados evidenciam que iniciativas de parcerias podem se reverter em melhoria da qualidade de ensino que permita o desenvolvimento de habilidades e competências necessárias à inserção responsável no mercado de trabalho com uma dimensão cidadã.

Consórcio de cártamo e feijão caupi: alternativa para a produção de biodiesel na agricultura familiar

The new development strategies should operate mainly in the areas of energy efficiency and sustainable agriculture. Thus, the substitution of fossil fuels with biofuels, such as biodiesel, is increasingly on the agenda. The cultivation of oilseed plants for biodiesel production must take place in integrated systems that enable best environmental benefits and are more economically significant. The objectives of this study were to assess the morphological, anatomic, and physiological characteristics of safflower (Carthamus tinctorius L., promising oilseed for biodiesel production) grown in monoculture and intercropping with cowpea bean (Vigna unguiculata L. Walp.); and identify socioeconomic family farmers and verify their acceptance about safflower as an energy crop. The methodology used for the analysis of safflower growth in monoculture and intercropped with beans, were morphoanatomical and histochemical analyzes, made with samples of plants grown in the field in two cropping systems throughout the range of the life cycle of these plants. There were no changes in growth and anatomy of plants, even in the consortium, which is satisfactory to indicate the intercropping system for those crops and can be a good alternative for the family farmer, who may have safflower as a source of income without giving up planting their livelihood. To check the acceptance of safflower by farmers, interviews were made to family farmers by Canudos agrovila in Ceará-Mirim/RN. It was noticed that many of them accept the introduction of safflower as oil crop, although unaware of the species, and that, being more resistant to drought, safflower help in the stability of families who depend on the weather conditions for success their current crops. In general, it is concluded that safflower has features that allows it to be grown in consortium for biodiesel production combined with the production of food, such as cowpea, and can be used enabling better development for family farmers.

Determinação da composição química de quatro variedades de feijão caupi (Vigna unguiculata L. Walp) cultivadas em solo potiguar

The cowpea (Vigna unguiculata L. Walp) is a major food crops in northeastern Brazil. In Rio Grande do Norte, the cowpea, vigna beans or cowpea, as it is known, has great socioeconomic importance as a source of nutrients in food, with great emphasis among agricultural products. To improve productivity and resistance to pests, two cultivars were developed exclusively by EMPARN (Agricultural Research Corporation of Rio Grande do Norte), for breeding. The samples were provided by EMPARN, two improved (Potiguar and Laugh year) and two landraces (Rib of beef and Canapu). The seeds were ground and made into flour samples and the determination of moisture and ash by graviméticos methods, lipids by Soxhlet extraction, fibers with determiner fiber, carbohydrates by difference and minerals by ICP-OES were performed except the match analyzed by UVvis. The results showed a high fiber content (55.55% and 55.32% and 50.04% improved samples and 50.32% creole samples) and protein (25.52% and 25.27% improved and 27 samples, 23% and 24.99% creole samples). Comparing the results of the mineral content, the improved cultivars stood out in relation to Ca, Co, P, Mg, Mo and Na. Creole cultivars showed better results for Cu, Cr (low), Fe, Mn, Ni, K and Zn. The results will be important in future nutritional research and to build a table of Brazilian chemical composition of foods.

Potencial do óleo de Aloysia citriodora Palau no controle de fitopatógenos e na indução de resistência ao tombamento de plântulas de feijão, pepino e beterraba

The crops are affected by pests and diseases that decrease productivity. Among them are the damping off of seedlings that can occur in pre and post-emergence. In bean crops, cucumber and beet these diseases occur, being caused by various pathogens, especialy fitopathogenic fungi. Several measures are used for the controle of such diseases, among them, is the chemical seed treatment fungicides. However, society has become increasingly concerned about the quality and food and environmental contamination, generation a growting search for sensitive products to humans and the environment. The use of essential oils to control plant pathogens is an example of alternative tested by science in the search for less aggressive technologies. This study aimed to evaluate the efficiency of the use of essential oil Aloysia citriodora, in control of pathogens causing damping off in beans, cucumber and beet. This thesis was divided in four chapters, the introductory first, and the other addressing the control of Pythium sp. in beans, Sclerotinia sclerotiorum on cucumber, and Fusarium sp. on beet. The methodology consisted of four experiments in each pathosystem, with all the work done at the Federal Technological University of Parana, Campus Dois Vizinhos. In the first experiment evaluated the fungistatic and fungicidal effect of the essential oil of A. citriodora on PDA in vitro in mycelial growth of pathogens studied. In the second experiment evaluated the in vitro effect of essential oil concentrations of A. citriodora in BD medium on microscope slides, on the germination of sporangia Pythium sp. and conidia Fusarium sp., and in Petri dishes with PDA medium, the sclerotia germination speed index of S. sclerotiorum. In the third experiment, we evaluated in germination test in paper roll (PR), the phytotoxic effect or not the use of essential oil concentrations of A. citriodora in dry bean seed, cucumber and beet. The variables used to assess this experiment were the germination percentage, mediun green mass per plant and average length of seedlings. In the fourth experiment we assessed the effect of treating bean seeds, cucumber and beet with essential oil contents of A. citriodora, seeds in their subsequent substrates contamined with pathogens studied, Pythium sp., S. sclerotiorum and Fusarium sp. In this experiment we used the following variables: percentage of emergence, percentage of post-emergence damping off, green average mass per plant, average length per plant and biochemical analyzes. The biochemistry of plant tissues evaluated were as follows: protein content, enzymatic activities of peroxidases, phenylalanine ammonia-liase (PAL), chitinases and β-1,3-glucanases. The in vitro results show that the essential oil has fungistatic and fungicidal effect on mycelial growth, on sporangia germination, conidia and sclerotia of the pathogens studied in this work, wich may be related to its major components, citral and limonene. The oil also exhibits low phytotoxicity to seeds of the species studied, only in beans decreases germination in most studied dosage (0,25%), cucumber also in the higher dosage (0,25%) reduce the length of seedlings, and beet there were no negative effects to the seedlings. In the test in substrate contaminated with the pathogens, the use of essential oil: increased germination and decreased post emergence damping off of beans seedlings; at a concentration of 0,0625% decreases post emergence damping off in cucumber. In biochemical analyzes found an increase in the enzymatic activity of peroxidases and β-1,3-glucanases on beans, and glucanases on cucumber, and increased enzyme activity of peroxidases on beet, showing action in resistance induction at damping off.

Caracterização da fração de óleo de café extraido de grãos sadios, verdes e preto-verdes, e a influência na adição deste na sensorial de café liofilizado

The application of roasted coffee oil directly on freeze dried soluble coffee is used to minimize the formation of fine poder which adhere on the glass packaging, which results in a negative visual appearance, as well as contributes to the aromatic impact when opening the packaging. The coffee oil is considered a high cost product obtained from Arabica coffee beans, previosly selected and roasted, by mechanical press. In Brazil the coffee culture and marketing results in the selection of the beans by type of defects and beverage, the volume of exportation works with types of coffee beans with low quantity of defects resulting in a large volume of defective coffee beans trading on the domestic market. Nevertheless, coffees which present defective grains like green, black-green beans present differences in the final flavor of the roasted coffees. The aim of this study was to evaluate the chemical composition of the oils extracted from grains classified as normal, green and black-green, at natural and roasted conditions. The oil was obtained by cold extraction using solvents of different polarities, and yield was calculated as well as its fatty acid composition. The oil of the roasted defective coffee grains was also used to prepare drinks of lyophilized soluble coffee in order to verify if jugdes were able to differenciate the sensory caracteristics of the beverages, in comparison to the product prepared using commercial oil obtained by mechanical pressing. Samples of oil obtained from defective grains showed similar extraction yields compared to hot extraction. Cromatographs of oils of the deffective grains did not showed differences compared to normal grains. In relation to the sensory analysis of the soluble coffee beverages, it was verified that when applying oils of light roasted black-green beans or oils of medium and dark roasted green beans obtained with rapid process, judges had more difficulties to distinguish differences between samples. Economic viability demonstrated that with the actual prices of the coffee beans, the use of defective beans could reduce in 64% the costs of the raw beans.

Influência do uso e ocupação do solo na qualidade da água e no processo erosivo da bacia de captação do Rio Barro Preto, Coronel Vivida-PR

This study was developed in objecting to investigate the use and occupation of land in 1999, 2005, 2011 e 2015 and estimate soil degradation by laminar erosion and the relation with water quality in 2015 in the catchment basin of the Barro Preto river, Coronel Vivida – PR. For multitemporal analysis of use and occupation of land in the basin used in the Landsat 5, 7 and 8 images and Geographic Information System. The laminar erosion was estimated by the Universal Soil Loss Equation through the systematization of calculations of the factors that compose the equation in SPRING/INPE. The water quality of the studied river section was evaluated according to the Water Quality Idex and the Resolution CONAMA n. 357/2005. The multitemporal analysis of the use and occupation of land has demonstrated that basin is predominantly agricultural in all years studied, as well as the permanent preservation area presents it not regularized during the period in accordance with the Brazilian Forest Code in force. In relation the quantification of laminar soil erosion in the study period, the rainfall and runoff factor was estimated considering the rainfall data from 1986 to 2014 and resulted in a value of 11.573,47 MJ/ha.mm/a. The Dystrophic Red Latosol, Dystrophic Red Nitisol, Fluvisol and Leptosol soil erodibility factor were 0,0138, 0,0137, 0,0207, 0,0196 t.ha.h/ha.MJ.mm/a, respectively. The topographical factor has demonstrated that the catchment basin has the rough terrain because the moderate and moderate strong classes are dominant in the study area. The cover and management and support practice factors were estimated according to the multitemporal analysis of the use and occupation of land in the basin and the values ranged from 0,0006 to 0,0688. The soil losses by laminar erosion were simulated with agriculture areas with corn and soybeans in no-till. The soil losses with maize crop in no-till in 1999, 2005, 2011 and 2015 were 9.782,75, 10.592,71, 9.636,61 e 11.058,26 t/year, respectively, and soybeans crops in no-till were 15.140,01, 16.645,20, 14.662,14 e 17.049,85 t/year, respectively. In relation with water quality of the section studied river, the average of Water Quality Index during the season were 55,47, 53,09 and 49,72, for the first, second and third sample point, respectively. Indication a decrease in water quality since the source to the last sample point. It is concluded that the use and occupation of land in the catchment basin interferes in the water quality, as well as in soil degradation.

Caracterização fisio-molecular de cultivares de feijão (Phaseolus vulgaris L.) em resposta à deficiência hídrica

The identification of genotypes for drought tolerance has a great importance in breeding programs. The aim of this study was to characterize genotypes of beans in response to drought tolerance in different reproductive stages through physiologic, agronomic and molecular analysis. The experiment was conducted in greenhouse, using a randomized block design with four replicates; 10 cultivars: ANFC 9, ANFP 110, BRS Esplendor, BRSMG Realce, IPR Siriri, IPR Tangará, IPR Tuiuiu, IPR Uirapuru, IAC Imperador and IAC Milênio under two conditions of irrigation: plants irrigated during their entire life cycle, and plants under irrigation suppression in the reproductive stage (R7) until 16% of field capacity, when the irrigation was restored. In the last four days of stress, the gas exchanges were analyzed, and in the last day of stress was analyzed the percentage of closed stomata in the abaxial surface of the leaves, collected in different times of the day (9h, 12h, 15h and 18h). Additionally, plant samples were collected for the following analysis: fresh and dry mass of leaves, stems and legumes, and proline content in leaves and roots. The plants were harvested at the physiological maturity and the yield components and grain yield were determined. In addition, in order to identify polymorphisms in the sequences of promoters and genes related to drought, seven pairs of primers were tested on the group of genotypes. The drought susceptibility indexes (ISS) ranged from 0.65 to 1.10 in the group of genotypes, which the lowest values observed were for IAC Imperador (0.65) and BRS Esplendor (0.87), indicating the ability of these two genotypes to maintain grain yield under water stress condition. All genotypes showed reduction in yield components under water stress. IAC Imperador (43.4%) and BRS Esplendor (60.6%) had the lowest reductions in productivity and kept about 50% of the stomata closed during all the different times evaluated at last day of irrigation suppression. IAC Imperador showed greater water use efficiency and CO2 assimilation rate under drought stress. IPR Tuiuiú, IPR Tangará and IAC Imperador had the highest proline concentrations in the roots. Under water stress condition, there was a strong positive correlation (0.696) between the percentage of stomata closed with the number of grains per plant (0.696) and the fresh mass of leaves (0.731), the maximum percentage of stomata closed 73.71% in water stress. The accumulation of proline in the root was the character that most contributed to the divergence between the genotypes under water deficit, but not always the genotypes that have accumulated more proline were the most tolerant. The polymorphisms in DNA of coding and promoting sequences of transcription factors studied in this experiment did not discriminate tolerant genotypes from the sensitive ones to water stress.

Avaliação da hidrólise alcalina da quitina e elaboração de filmes de quitosana para aplicação na adsorção do corante têxtil reativo preto 5

Nesta pesquisa, diferentes amostras de quitosana foram produzidas por diferentes condições de hidrólise alcalina da quitina. A partir das amostras de quitosana foram produzidos filmes,sendo estes aplicados na adsorção do corante têxtil reativo preto 5 e os resultados foram comparados com os dos seus respectivos pós. Os valores das massas molares da quitosana aumentaram em função do aumento do diâmetro da quitina e diminuíram com o aumento da relação de solução NaOH:quitina, da concentração de NaOH e tempo de reação, e ficaram na faixa de 100 a 200 kDa. Um comportamento inverso foi observado para o grau de desacetilação da quitosana, e seus valores variaram de 65 a 95%. Quanto aos filmes biopoliméricos elaborados, os que apresentaram melhores valores quanto as suas propriedades mecânicas e de permeabilidade ao vapor de água foram os filmes produzidos com quitosana de mais elevada massa molar e menor grau de desacetilação. A fim de avaliar o comportamento dos filmes em processos de adsorção, estes foram aplicados na remoção do corante reativo preto 5 (RB5) em diferentes condições de pH (4, 6 e 8). Após, foram escolhidos quatro filmes de quitosana (FQ), com diferentes graus de desacetilação e massas molares, que foram comparados com as quitosanas na forma de pó (PQ) no estudo de adsorção. Este foi realizado sob diversas condições experimentais (pH, temperatura e taxa de agitação) através das isotermas de equilíbrio, da termodinâmica e da cinética. Análises de interação e ciclos de adsorção-dessorção também foram realizados. Verificou-se que PQ e FQ com grau de desacetilação de 95% e massa molar de 100 kDa foram os adsorvente mais adequados, apresentando mais de 99% de remoção do corante RB5 em pH 4,0. Para ambos, PQ e FQ, o modelo de Langmuir foi o mais adequado para representar os dados de equilíbrio. As capacidades máximas de adsorção foram 654,3 e 589,5 mg g-1 para PQ e FQ, respectivamente, obtidos a 298 K. O processo de adsorção foi espontâneo, favorável e exotérmico. A adsorção de RB5 para PQ e FQ seguiu o modelo cinético de Elovich,e ocorreram interações eletrostáticas do PQ-RB5 e do FQ-RB5. Os filmes de quitosana foram reutilizados três vezes, enquanto que a quitosana em pó não pode ser reutilizada.
