Full textThe use of plant extracts in animal feeding trials has been considered as a potential alternative to improve the redox stability of meat. Bioactive compounds from plant extracts can provide the antioxidative mechanisms required to improve animal health and welfare and, to protect meat against oxidation. Pharmacological properties and antioxidant effects have been associated to the extract of hops and to the extracts of yerba mate. However, the effects of hops and yerba mate as dietary supplement for animal feeding on the metabolic profile and the redox stability of meat have not been reported yet. Addition of extract of mate to a standard maize/soy feed at a level of 0.5, 1.0 or 1.5% to the diet of feedlot for cattle resulted in an increased level of inosine monophosphate, creatine, carnosine and of conjugated linoleic acid in the fresh meat. The tendency to radical formation in meat slurries as quantified by EPR spin-trapping decreased for increasing mate extract addition to feed especially after storage of the meat indicating an increased resistance to oxidation for meat. Addition of hops extract at different levels (0, 30 ppm, 60 ppm, 240 ppm) to the diet of broilers demonstrated to have significant effects on the averaged concentration of polar metabolites that are of relevance for meat quality. The major metabolic differences between control group (no supplements) and broilers fed different levels of β-acids were achieved using 30 ppm of supplement. As determined by EPR spin-trapping, increased redox stability was obtained in the samples referring to the animals fed 30 ppm of lupulones and may be related to the highest level of endogenous antioxidants, especially anserine, carnosine and NADH. Myosin and actin were recognized as the main targets of protein oxidation in meat. Myofibrillar proteins from animals fed with hops β-acids showed to be less susceptible to oxidation when compared to control group. Mate and hops β-acids extracts demonstrated to be promising additives to feedlot for, respectively, cattle and broilers and can improve the oxidative stability, nutritive value, sensory quality, and consumer acceptance of meat.

Full textThe herb mate is a Brazilian tree species from the South and Midwestern of Brazil. The quality of its product is determine by its answers to ecophysiological stress, since it is a climax plant which natural habitat is a microenvironment sheltered by larger arboreal extracts. The use of herb mate leaves and branches as chimarrão and tererê beverages are the best-known and popularized ones in the Southern states of Brazil. Currently, there has been a strong competition from more profitable annual crops expanding, and a growing demand for pharmaceutical and food industries due to its rich composition in phenolic compounds and antioxidants, which concentration depends on the production environment condition, resulting in prices increase of the products obtained and the demand for more favorable environment to high quality. Thus, more appropriate cultivation and handling practices are necessary to different micrometeorological conditions, depending on the region and time of year. The objective of this study was to evaluate the ecophysiological responses of herb mate under different levels of shading, concerning the effect of soil cover by plant residues, and mechanical stress resulting from the increase of wind speed. Two experiments were conduct with the DF /UFSM. In experiment one, conducted with young plants of herb mate, the field, the land cover factor (covered and bared soil) and the percentage factor of plants shading (0, 18, 35 and 50%) were evaluated in a completely randomized design. Each sample consisted of 12 plants of a progeny with four replications. In experiment 2, conducted in field by taking advantage of a side protection structure of an old greenhouse, the shading factors were tested (18 and 35%) and wind speed (natural ( 0), 2, 4 and 6 m s-1), being tht each sample had 12 plants in three repetitions. Ventilation was generated by portable fans of different powers. The results showed that the soil cobetura is beneficial for young plants having an increased height, the number of sprouts and more intense staining green hue. The shading of 35 and 50% had higher gain in dry mass, higher leaf area, more intense green color and increased stomatal opening. As the phytochemical composition the concentration of polyphenols and flavonoids was higher in sombremamentos getting 35% higher antioxidant capacity. The application of forced ventilation reduced the number of shoots and stomatal opening, and the leaves were less intense green color and slightly altering the phytochemical composção of phenolic compounds and flavonoids and antioxidant capacity. Young erveiras have better establishment to higher growth and better development with greater accumulation of phytochemicals compounds covered soils with partial shading of 50% and places with little wind.
A erva-mate (Ilex paraguariensis St. Hil.) é uma planta arbórea nativa do Sul e Centro-Oeste brasileiro. A qualidade de seu produto é determinada pelas respostas dessa planta a estresses ecofisiológicos, por tratar-se de uma planta climácica em que seu habitat natural é um microambiente abrigado por extratos arbóreos maiores. A utilização das folhas e ramos da erva-mate como chimarrão e tererê são os mais conhecidos e popularizados nos estados da região Sul do Brasil. Atualmente observa-se uma forte competição com culturas anuais mais rentáveis em expansão e uma demanda crescente pela indústria farmacêutica e alimentícia, devido a sua composição rica em compostos fenólicos e antioxidantes, cuja concentração depende da condição do ambiente de produção, resultando em aumento dos preços dos produtos obtidos e na procura do ambiente mais favorável à alta qualidade. Assim, são necessárias práticas de cultivo e manejo mais adequadas às diferentes condições micrometeorológicas, decorrentes da região e da época do ano. O objetivo deste trabalho foi o de avaliar as respostas fenométricas e qualidade da erva-mate sob diferentes níveis de sombreamento, quanto ao efeito da cobertura do solo por restos vegetais e ao estresse mecânico ocasionado pelo aumento da velocidade do vento. Foram conduzidos dois experimentos junto ao Departamento de Fitotecnia UFSM. No experimento 1 conduzido com plantas jovens de erva-mate, a campo, avaliou-se o fator cobertura do solo (solo coberto e desnudo) e o fator percentual de sombreamento das plantas (0, 18, 35 e 50%) em um delineamento inteiramente causualizado. Cada parcela se constituiu de 12 plantas de um progênie, com 4 repetições. No experimento 2, conduzido a campo com uma estrutura de proteção lateral foram, testados os fatores sombreamento (18 e 35%) e o velocidade do vento (natural ( 0), 2, 4 e 6 m s-1), sendo cada parcela constituída por 12 plantas, em três repetições. A ventilação foi gerada por ventiladores portateis de diferentes potências. Os resultados demonstraram que a cobetura do solo é benéfica para as plantas jovens havendo um aumento na altura, no número de brotos e coloração com tonalidade verde mais intenso. Os sombreamentos de 35 e 50% apresentaram maior ganho na massa seca, maior área foliar, cor verde mais intensa e aumento da abertura estomática. Quanto a composição fitoquímica a concentração de polifenóis e flavonoides foi maior nos sombremamentos 35% obtendo maior capacidade antioxidante. A aplicação da ventilação forçada reduziu o número de brotos e a abertura estomática, sendo que as folhas apresentaram coloração verde menos intensa e pouco alterando a composção fitoquímica dos compostos fenólicos e flavonoides e a capacidade antioxidante. As erveiras jovens possuem uma melhor estabelecimento com maior crescimento e melhor desenvolvimento com maior acúmulo de compostos fitoquímicos em solos cobertos, com sombreamento parcial de até 50% e locais com pouco vento.

Full textThis work was aimed at evaluating the effect of the exposure to stressing ammonia and oxygen levels in vivo as well as the effect of the treatment with erva-mate extract (Ilex paraguariensis) post mortem on the lipid stability of fillets of dourado (Salminus brasiliensis). The influence of different levels of ammonia and oxygen on the proximate composition, fatty acid composition and lipid peroxidation of dourado fillets, as well as on the stability of these fillets during the frozen storage (12 months at -7±1oC) was evaluated. The effect of erva-mate extract on lipid and colour changes of raw fillets of dourado during the frozen storage and on the sensory characteristics and lipid oxidation of cooked dourado fillets during chilled storage was also evaluated. The exposure of dourado during 15 days at high ammonia concentration (0.1 mg/L) affected the composition of fillets, while the exposure to high oxygen (> 6.0 mg/L) increased the value of thiobarbituric acid reactive substances (TBARS) measured immediately after slaughtering. However, the in vivo exposure to stressing ammonia and oxygen levels for 12 hours, did not change TBARS formation during the frozen storage. A 12-hours exposure to high ammonia increased the susceptibility of fillets to lipid oxidation during the frozen storage (higher conjugated dienes and peroxides values). On the other hand, the exposure to low oxygen concentration (4.5 mg/L) did not increase the lipid oxidation of fillets. The aqueous 10% (w/v) erva-mate extract had an antioxidant capacity equivalent to 25.8 mg trolox/mL extract in the DPPH radical scavenging assay. The treatment of dourado fillets with this extract (fillets dipped in the extract for 1 min) reduced the colour changes during frozen storage (lower changes in luminosity and hue values) and the fillets treated with erva-mate extract had lower increase of free fatty acids, conjugated dienes and TBARS values during the frozen storage (12 meses at - 7±1oC). The treatment of dourado fillets with aqueous crude 10 or 20% erva-mate extract did not modify the taste, but caused important changes in the colour (decrease of luminosity and increase in the yellowness) of cooked dourado fillets. Since crude erva-mate extract changed the colour, it was decided to purify the extract in order to eliminate chlorophyll and other pigments. Liquid-liquid partition yielded a clear upper phase with antioxidant activity in the DPPH radical scavenging assay (1.2 vs. 0.7 mg trolox equivalents/ml extract, upper phase vs. lower phase). The purified erva-mate extract reduced peroxides, but had no significant effect on the content of TBARS of cooked dourado fillets during chilled storage (6 dias at 7±1oC). No effect of ammonia or oxygen was observed on the fatty acid composition. Similarly, there was no effect of the frozen storage or of the treatment with erva-mate extract. The results indicate that the exposure to high ammonia levels increased the susceptibility of fillets to lipid oxidation during the frozen storage. In addition, ervamate had antioxidant activity in frozen fillets and some protective effect against lipid oxidation of cooked dourado fillets under chilling storage. This demonstrates the possible use of erva-mate to extend the shelf-life of fish fillets.
Este trabalho teve como objetivo avaliar os efeitos da exposição in vivo a concentrações estressantes de amônia e oxigênio na água e do tratamento com extrato de erva-mate (Ilex paraguariensis) post mortem sobre a estabilidade lipídica de filés de dourado (Salminus brasiliensis). Foi avaliada a influência de diferentes níveis de amônia e oxigênio sobre a composição centesimal, composição de ácidos graxos e a peroxidação lipídica de filés de dourado, assim como a estabilidade desses filés durante o armazenamento congelado (12 meses a -7±1oC). Avaliou-se também o efeito do extrato de erva-mate sobre alterações lipídicas e de cor de filés crus de dourado durante o armazenamento congelado e sobre as características sensoriais e a oxidação lipídica de filés cozidos de dourado durante o armazenamento refrigerado. A exposição do dourado durante 15 dias a alta concentração de amônia (0,1 mg/L) afetou a composição dos filés e a exposição a alto oxigênio (>6,0 mg/L) aumentou os valores de substâncias reativas ao ácido tiobarbitúrico (TBARS) medidos logo após o abate. No entanto, a exposição in vivo a níveis estressantes de amônia e oxigênio por 12 horas, não afetou a formação de TBARS durante o armazenamento congelado. A exposição durante 12 horas à alta amônia aumentou à susceptibilidade dos filés a oxidação lipídica durante o armazenamento congelado (maiores valores de dienos conjugados e peróxidos). Por outro lado, a exposição à baixa concentração de oxigênio (4.5 mg/L) não aumentou a taxa de oxidação lipídica dos filés. O extrato aquoso de erva-mate 10% (p/v) apresentou uma capacidade antioxidante equivalente a 25,8 mg trolox/ml extrato no ensaio de remoção do radical DPPH. O tratamento dos filés com este extrato (filés mergulhados por 1 min no extrato) reduziu as alterações de cor durante o armazenamento congelado (menor alteração de luminosidade e ângulo de matiz) e os filés tratados com o extrato de erva-mate apresentaram menor aumento nos valores de ácidos graxos livres, dienos conjugados e TBARS durante o congelamento (12 meses a -7±1oC). O tratamento dos filés de dourado com extrato bruto de erva-mate (10 e 20%) não alterou o sabor, mas provocou importantes alterações de cor (redução na luminosidade e aumento na tendência ao amarelo) dos filés cozidos de dourado. Como o extrato bruto alterou a cor, decidiu-se purificar o extrato de erva-mate para eliminar a clorofila e outros pigmentos através de partição líquido-líquido, obtendo-se uma fase superior límpida com atividade antioxidante no ensaio de remoção do radical DPPH (1,2 vs. 0,7 mg equivalentes de trolox/ml extrato, fase superior vs. fase inferior). O extrato purificado de erva-mate reduziu o valor de peróxidos, sem efeito significativo no conteúdo de TBARS de filés cozidos de dourado durante a armazenagem refrigerada (6 dias a 7±1oC). Não foi observado efeito da amônia ou do oxigênio sobre a composição de ácidos graxos, da mesma maneira que não houve influência do armazenamento congelado ou do tratamento com extrato de erva-mate. Os resultados indicam que a exposição a altos teores de amônia aumentou à susceptibilidade dos filés a oxidação lipídica durante o armazenamento congelado e a erva-mate apresentou atividade antioxidante nos filés congelados e certa proteção contra a oxidação de filés de dourado cozidos e armazenados sob refrigeração. Isto demonstra o possível uso da erva-mate para estender a vida útil de filés de pescados.

Full textIn mutually ornamented species, female conspicuous traits could be non-functional by-products of sexual selection acting on male traits or could be directly under selection. The aim of this PhD was to test the hypothesis of sexual selection in Blue tit (Cyanistes caeruleus) females on three traits present in both males and females: (1) the structural coloration of the UV/blue crown, (2) the yellow chest coloration based on carotenoids and (3) aggressiveness. To do so, we experimentally tested (1) the links between plumage coloration and the transfer of potentially beneficial components in egg yolks, (2) the condition-dependence of the plumage coloration, (3) the use of the plumage coloration in female-female interactions and (4) the link between female aggressiveness and investment in reproduction. Finally, we explored the role of female plumage coloration in male mate choice by testing the link between female UV/blue crown coloration and the n umber of extra-pair young in the nest and by estimating whether the individuals were assortatively mated in respect of their yellow and blue coloration in the studied population. Our results suggest that (1) there is a link between female plumage coloration and maternal quality, (2) plumage UV/blue and yellow coloration is condition-dependant, (3) the UV/blue crown is used as a badge of status in female-female interactions, (4) there could be a trade-off between female aggressiveness and female investment in reproduction and (5) there is a potential mutual mate choice based on both coloration. So, this PhD supports the hypothesis that in a mutually ornamented species, female ornaments are potentially under direct sexual selection

Full textLa tesis tiene como objetivo analizar el concepto de calidad y discutir de forma unificada su papel tanto en la dirección de operaciones como en el pensamiento estratégico. El trabajo argumenta en contra de la opinión generalizada de que la calidad es satisfacer las necesidades y expectativas del cliente de tal manera que la diferencia entre percepciones y expectativas se reduzca. Se desarrolla una propuesta sistemática con el fin de entender el concepto sobre la base intuitiva de que la calidad se relaciona con lo bien que funcionan las cosas para un fin determinado. El análisis se basa en el hecho de que cualquier uso del concepto de calidad supone que hay actores que realizan una acción con la ayuda de un medio. En consecuencia, la calidad es un tipo particular de relación entre medios y fines. En términos generales, la calidad de un medio es su capacidad para mejorar las consecuencias esperadas de la acción. El análisis muestra cómo ésta conclusión puede entenderse en términos de preferencias multiatributo bajo condiciones de incertidumbre. Que las consecuencias sean mejores o no depende de suponer una relación de preferencias que debe ser correcta dados los propósitos y circunstancias de los actores, pero que puede ser distinta de las preferencias reales de muchos actores individuales. La calidad no es subjetiva (no cambia en función de los procesos psicológicos de un individuo en particular) ni objetiva (en cierto sentido, depende de la acción y la cognición), sino que es relativa a ciertas preferencias de referencia. En la tesis se estudia qué se considera un medio, cómo se relaciona con un fin, qué atributos son relevantes, cuándo las preferencias de referencia están bien formadas, y a qué tipo de medios tiene sentido aplicar el concepto. Como complemento, se presenta un modelo simple (construido a partir de propiedades de las funciones booleanas) sobre relaciones medios-fines. El concepto de calidad aparece en la gestión bajo dos formas interrelacionadas: (a) las actividades de las organizaciones para intervenir en la calidad de lo que utilizan y proporcionan, y (b) las iniciativas para competir a través de la calidad. (a) Las actividades básicas de la gestión de la calidad se examinan bajo la perspectiva del análisis del concepto: definición de criterios de calidad, diseño de productos, diseño de procesos, planificación operativa, control, estandarización, mejora del producto, mejora de procesos, y redefinición de las preferencias de referencia. (b) El papel de la calidad en la rentabilidad y la ventaja competitiva sostenibles depende de cómo la calidad se relaciona con las barreras de entrada. El trabajo trata diferentes formas en que la calidad puede interactuar con la diferenciación del producto, los efectos de aprendizaje, las economías de alcance, la reputación, los requisitos de capital, el acceso a canales de distribución, los efectos red, las barreras legales o las economías de escala. Se argumenta que no es fácil de construir ventajas competitivas sostenibles solamente sobre la base de la calidad; su papel complementario en otras estrategias competitivas tiene varios aspectos a considerar. Por último, se trata el ejemplo concreto de la calidad de los flujos de información (procesos que mueven información desde el entorno hasta las decisiones para modificarlo). Se estudian, y se ilustran mediante dos casos reales, los factores decisivos de su calidad: la coherencia y las asimetrías en la información. El ejemplo de la información tiene por objetivo mostrar la necesidad de un análisis del concepto de calidad más allá de exhortaciones sobre clientes, productos, percepciones y expectativas.
L’objectiu de la tesi és analitzar el concepte de qualitat i discutir de forma unificada el seu paper tant en la direcció d'operacions com en el pensament estratègic. El treball argumenta en contra de l'opinió generalitzada de que la qualitat consisteix en satisfer les necessitats i expectatives del client de manera que la diferència entre percepcions i expectatives es redueixi. Es desenvolupa una proposta sistemàtica per tal d'entendre el concepte sobre la base intuïtiva de que la qualitat es relaciona amb com de bé funcionen les coses per una finalitat determinada. L'anàlisi es basa en el fet que qualsevol ús del concepte de qualitat suposa que hi ha actors que realitzen una acció amb l'ajuda d'un mitjà. En conseqüència, la qualitat és un tipus particular de relació entre mitjans i fins. En termes generals, la qualitat d'un mitjà és la seva capacitat per millorar les conseqüències esperades de l'acció. L'anàlisi mostra com aquesta conclusió es pot entendre en termes de preferències multiatribut sota condicions d'incertesa. Que les conseqüències siguin millors o no depèn de suposar una relació de preferències que ha de ser correcta donats els propòsits i circumstàncies dels actors, però que pot ser diferent de les preferències reals de molts actors individuals. La qualitat no és subjectiva (no canvia en funció dels processos psicològics d'un individu en particular) ni objectiva (en certa manera, depèn de l'acció i la cognició), sinó que és relativa a certes preferències de referència. En la tesi s'estudia què es considera un mitjà, com es relaciona amb un fi, quins atributs són rellevants, quan les preferències de referència estan ben formades, i a quin tipus de mitjans té sentit aplicar el concepte. Com a complement, es presenta un model simple (construït a partir de propietats de les funcions booleanes) sobre les relacions entre mitjans i fins. El concepte de qualitat apareix en la gestió sota dues formes interrelacionades: (a) les activitats de les organitzacions per intervenir en la qualitat d’allò que fan servir i proporcionen, i (b) les iniciatives per competir a través de la qualitat. (a) Les activitats bàsiques de la gestió de la qualitat s'examinen sota la perspectiva de l'anàlisi del concepte: definició de criteris de qualitat, disseny de productes, disseny de processos, planificació operativa, control, estandardització, millora del producte, millora de processos , i redefinició de les preferències de referència. (b) El paper de la qualitat en la rendibilitat i l'avantatge competitiu sostenibles depèn de com la qualitat es relaciona amb les barreres d'entrada. El treball tracta diferents formes en les que la qualitat pot interactuar amb la diferenciació del producte, els efectes d'aprenentatge, les economies d'abast, la reputació, els requisits de capital, l'accés a canals de distribució, els efectes xarxa, les barreres legals o les economies d'escala. S'argumenta que no és fàcil construir avantatges competitius sostenibles només sobre la base de la qualitat; el seu paper complementari en altres estratègies competitives té diversos aspectes a considerar. Finalment, es tracta l'exemple concret de la qualitat dels fluxos d'informació (processos que mouen informació des de l'entorn fins a les decisions per modificar). S'estudien, i s'il•lustren mitjançant dos casos reals, els factors decisius de la seva qualitat: la coherència i les asimetries en la informació. L'exemple de la informació té per objectiu mostrar la necessitat d'una anàlisi del concepte de qualitat més enllà d’exhortacions sobre clients, productes, percepcions i expectatives.

Full textIt is observed how the life quality of people is affected while having to carry out a large amount of activities leaving little time to enjoy with friends or family. Also, many times it can happen that you do not have the proper skills to perform tasks at home such as plumbing, locksmith, painting, cleaning or electrician. For this reason, we have developed a new business model, which offers simplicity, safety and quality in each of its services aimed at home care, which we call Make it Easy. It's intended to reach the final customer through a close interaction with them where they can perceive positive attributes of the brand, this will mainly be through actions on social networks and activations at strategic points. On the other hand, regarding the recruitment of our technicians it is considered that this is possible through advertisements in different places such as large home improvement chains in which related services are offered or also large posters located in kiosks. It is necessary to indicate that the segment to be attended are people from socioeconomic level A and B who live in zones 6 and 7 of the city of Lima, according to the APEIM classification; which gives us a market of S /. 13 659 651 of which we intend, with an initial investment of S /. 65,409.67, obtain 1%; as well as obtaining a Net Present value of S / 191,136.38 and an internal rate of return of 94.2% projected to 3 years.

Full textThe purposes of this study were (1) to identify selected consumers' attitudes toward purchasing domestic- made shirts and those imported from a low-wage country, and (2) to evaluate the relative effects of price, brand name, and country-of-origin on perception of quality of menâ s dress shirts. A convenience sample of 120 male undergraduate students registered at Virginia Tech completed questionnaires in selected classes.
Research hypotheses that consumers' attitudes toward selected beneficial and imagery attributes would be more positive for domestic shirts than for imported shirts were supported in the single cue situation. The effects of price, brand name and country-of-origin on consumers' quality perception were significant with price and brand name slightly more important than country-of-origin. The interactions between price and country-of-origin, and between brand name and country-of-origin were not significant.

Full textIndustrial cities still maintain structures for a mass production and consumption dynamics, which result in several issues such as unemployment, homeless, traffic jams, pollution, diseases, violence and so on. This urban industrial configuration no longer fits with the value creation principles of the new techno-economic paradigm. The dynamics of the new techno-economic paradigm demand that cities redeem their very essence in order to start a new cycle of wealth creation. In order to overcome this crisis and encompass this new dynamics, cities of the future must find suitable trajectories to become smart cities. However, there is no consensus about what really makes a city smarter. What is a smart city? What are the driving elements that can enhance the smartness of a city? The objective of this study is to propose an integrated framework in order to understand the process to make cities smarter To achieve this objective, it was realized a systematic literature review and a multiple case studies from smart cities projects in four European cities (Amsterdam, Barcelona, Lisbon, Vienna) where some experts were interviewed. Results show that cities to become smarter should integrate their dimensions and elements in order to offer high quality of life and a prosperous environment for innovation and creativity in the most sustainable way. If a city wants to start this process of transformation, it should develop some specific projects that that use and improve its enviro-urban configuration, its techno-economic dynamics and its socio-institutional structure in order to create wealth through a comprehensive innovation process. Therefore, the challenge to make a city smarter lies on defining how to articulate those driving elements in each dimension properly in order to build up its own urban innovation ecosystem.

Full textThe aim the thesis was to investigate, the prevalence of Lower Urinary Tract Symptoms (LUTS). Moreover, we examine symptom severity and different levels of distress and describe how different symptoms from the lower urinary tract affect the self-assessed health, sadness, happiness and the quality of life in men.
The studies are based on two data collections. In the first data collection, all men aged 40 – 80 years (n=2571) living in the Swedish community received a postal questionnaire. Twelve months later, 504 men who had earlier reported LUTS and 504 who had not reported symptoms were asked to complete the DAN-PSS and the SF-36 questionnaires.
The overall prevalence of LUTS was 24%. Post-micturition dribbling (21%) was the most frequent symptom, and stress incontinence (2%) was the least frequent symptom. Urge incontinence, stress incontinence and “other” incontinence cause a high level of distress, even if the symptoms do not occur very often. Men experiencing mild, moderate or severe urge, stress or “other incontinence” had lower mean scores for all of the eight dimensions measured by the SF-36 than men without the same symptoms. Men experiencing a moderate/severe degree of weak stream or nocturia reported a poorer quality of life in all dimensions compared to men with a mild level of the same symptoms. The total burden of moderate/severe LUTS is related to self-assessed health, sadness and happiness. For each of the 12 specific LUTS, men with mild, moderate or severe symptoms had lower scores for self-assessed health and happiness, and higher scores for self-assessed sadness, than men without the same symptoms.
In conclusions, one of every four men reports LUTS. Urinary incontinence causes high level of distress even to men who experience this symptom rarely. LUTS have a negative impact on quality of life, health, sadness and happiness.

Full textThe purpose of this qualitative exploratory multiple-case study was to explore the lived experiences and the challenges African American male nurses faced in leadership roles and in providing quality care for minority patients. Participants included 15 African American male registered nurses (RNs) working in executive, administrative, and managerial leadership positions in Florida’s hospitals and other healthcare organizations. The participation criteria included being an African American male RN working in a leadership position in Florida with experiences in leadership and providing quality care for minority patients and at least 5 years of leadership experience. Participants completed in-depth face-to-face, digitally recorded interviews answering open-ended questions. Analysis of the interview data identified emerging themes and patterns using NVivo 10 qualitative data analysis software. Four major themes were identified: (a) specific leadership challenges associated with being an African American male leader, (b) general leadership challenges, (c) patient-level challenges limit the ability to provide quality care for minority patients, and (d) systemic challenges limit the ability to provide quality care for minority patients. Recommendations to healthcare leaders include a work environment free of gender segregation and racial discrimination, organizations adequately funded to deliver quality care, and strong leadership support for nurses and staff. Future studies should include additional geographic locations to increase the generalizability of findings to other populations.

Full textA germinação pré-colheita é um dos principais problemas da triticultura mundial. Na germinação pré-colheita ocorrem transformações bioquímicas próprias da germinação que também ocorrem na maltagem, porém sem controle e com intensidade variável. O objetivo do presente estudo foi avaliar o uso de trigo com germinação pré-colheita na produção de malte. Treze amostras de trigo com germinação pré-colheita obtidas de diferentes regiões do Paraná e Rio Grande do Sul foram analisadas a fim de avaliar a intensidade das mudanças nas propriedades físicas, composição química e atividade enzimática, em função da intensidade do dano causado pela chuva. Foram avaliados falling number (FN), peso hectolitro, peso de mil sementes, nitrogênio total, nitrogênio solúvel (NS), nitrogênio de aminoácidos livres (NAL), cinzas, açúcares redutores, atividade enzimática e alterações na fração de gliadina. A segunda etapa teve como objetivo otimizar a maltagem de uma amostra de trigo com germinação pré-colheita, utilizando metodologia de superfície de resposta e avaliando o efeito da temperatura de embebição e germinação, umidade inicial de germinação e tempo de germinação. Os maltes foram avaliados quanto as perdas de maltagem, extrato, atenuação limite, viscosidade, atividade de α e β-amilase, nitrogênio total, NS e NAL. Na terceira etapa foi avaliada a qualidade do malte de amostras de trigo com diferentes intensidades de germinação pré-colheita, quanto às perdas de maltagem, extrato, atenuação limite, viscosidade, atividade de α e β-amilase, nitrogênio total, NS e NAL. Nas amostras de trigo com germinação pré-colheita, as variáveis açúcares redutores, NS, NAL, atividade de α-amilase, β-glucanase e protease apresentaram correlações significativas com FN. À medida que houve redução do falling number, as gliadinas apresentaram alterações nas bandas entre 40 e 30 KDa que ficaram mais intensas. No estudo de otimização da maltagem, a temperatura de embebição e germinação foi o fator que influenciou um maior número de parâmetros de qualidade do malte, seguido por tempo de germinação e umidade inicial de germinação. A metodologia de superfície de resposta possibilitou otimizar a maltagem do trigo, e as melhores condições definidas pela ferramenta de desejabilidade foram 45% de umidade inicial, embebição e germinação a 12,5oC e germinação por 78 horas. A maltagem de amostras com diferentes intensidades de germinação pré-colheita nas condições anteriormente citadas, produziram maltes que atenderam aos parâmetros de viscosidade, extrato, níveis de perdas, nitrogênio de aminoácidos livres, nitrogênio solúvel e índice de Kolbach. A amostra com falling number acima de 200 s apresentou nitrogênio solúvel inferior; mas atividade de α e β-amilase e extrato, superiores às amostras com germinação pré-colheita. O conjunto de resultados obtidos indica a viabilidade técnica de produção de maltes de trigos com germinação pré-colheita.
The preharvest sprouting damage (PHSD) is one of the main problems in world wheat crop. During the preharvest sprouting typical germination biochemical process occurs, which also happens in malting, but without control and with variable intensity. The aim of this study was to evaluate the use of preharvest sprouted wheat in malt production. Thirteen samples of preharvest sprouted wheat were collected in Paraná and Rio Grande do Sul states and were analyzed to assess the changes in physical properties, chemical composition and enzyme activity, due to rain damage. Falling number (FN), hectoliter weight, thousand seed weight, total nitrogen, soluble nitrogen (SN), free amino acid nitrogen (FAN), ash, reducing sugars, enzyme activity and changes in the gliadin fraction were investigated. In the second study response surface methodology was used to optimize the malting of preharvest sprouted wheat. The influence of three malting parameters (degree of steeping, germination time and temperature) on the quality of wheat malt was investigated. Malt quality was evaluated as malting losses, extract, attenuation limit, viscosity, α and β-amylase activity, total nitrogen, Kolbach index, SN and FAN. In the third study, the quality of preharvest sprouted wheat malt containing various levels of PHSD was investigated about malting losses, extract, attenuation limit, viscosity, α and β-amylase activity, total nitrogen, Kolbach index, SN and FAN. In samples of preharvest sprouted wheat, reducing sugars, SN, FAN, α and β-amylase activity, and protease activity showed significant correlations with FN. In samples with lower falling number values, the gliadins displayed changes to the 40 and 30 kda bands, which become more intense. In the malting optimization study, temperature of malting was the factor that influenced a greater number of malt quality parameters, followed by germination time and degree of steeping. The response surface methodology enabled to optimize the malting of the wheat, and the best conditions defined by the desirability tool were degree of steeping 45%, temperature 12.5oC and germination time 78 hours. Wheat malt samples containing various levels of PHSD reached the desible parameters: viscosity, extract, malting losses, free amino nitrogen, soluble nitrogen and kolbach index. The sample with falling number greater than 200 s showed lower soluble nitrogen concentration; but higher α and β-amylase activity and extract than the samples of preharvest sprouted wheat with lower values of falling number. The set of results indicates that is possible to produce malt, using pre-harvest sprouting wheat.
