Iowa Comprehensive Heart Disease and Stroke Plan, 2010-2014, March 22, 2010

Heart disease is the number one cause of death for both men and women nationally as well as in the state of Iowa, while stroke is the third leading cause of death. These two diseases are often grouped together under the broader term ―cardiovascular disease‖ (CVD), which accounts for one-third of all deaths within the state. Ongoing efforts to increase prevention of, and improve care for, those who experience CVD have resulted in a decline in the number of deaths in Iowa caused by these conditions. In 1991, the death rate as a result of cardiovascular disease was 344.9 per 100,000 people; by 2006, that number had fallen to 239.9. Deaths as a result of stroke have also dropped, from 74.7 in 1991 to 57.4 in 2006.1 Although progress has been made; these illnesses are still major causes of death and serious disability for many Iowans. Despite the fact that some progress has been made through past efforts, current data show that the journey must continue to achieve the long, quality filled lives that Iowans deserve, free of chronic disease. Up to this point, there has been a lack of involvement by stakeholders against heart disease and stroke in Iowa. Causes of CVD are largely known and preventable, and more must be done to educate and spread this information throughout the state. This comprehensive statewide plan is a call to action to improve prevention, treatment, and management of heart disease and stroke in Iowa. Through the commitment and collaborative efforts of many, the Iowa Comprehensive Heart Disease and Stroke Plan 2010-2014 provides a guide to improve the health status of all Iowans. The people of Iowa have a long history of working together to do the right thing. We must rise to the challenge of lowering the incidence of heart disease and stroke through early and ongoing education that stresses prevention and healthy lifestyle choices, medical services that provide evidence-based, effective treatment and long term care management without disparity, and environmental policies that support the prevention of heart disease and stroke in our schools, work sites, and communities. This strategic plan is a guide to improving cardiovascular health in Iowa through 2014.

Desempenho de cultivares de morango submetidas a diferentes tipos de polinização em cultivo protegido

O objetivo deste trabalho foi avaliar o efeito de diferentes tipos de polinização sobre a qualidade de frutos de cultivares de morangueiro e sua contribuição isolada para a massa dos frutos, bem como determinar o potencial de Plebeia nigriceps (Hymenoptera: Apidae, Meliponini) como agente polinizador em ambiente protegido. As cultivares Aromas, Diamante e Cegnidarem foram submetidas a tratamentos com autopolinização, polinização por P. nigriceps e polinização livre. Os experimentos foram conduzidos em estufa tipo pampeana, coberta com polietileno transparente e desprovida de telas anti-insetos nas laterais, com 1.344 plantas. Para as avaliações, foram marcadas 56 flores primárias em botão, de cada cultivar, e considerou-se cada planta uma repetição. Avaliaram-se massa de matéria fresca, peso, diâmetro, comprimento e presença de deformação nos frutos. A polinização entomófila tem contribuição variada à massa dos frutos, de acordo com a cultivar. As cultivares apresentam sensibilidade variada à autopolinização, no que se refere à incidência de frutos deformados. A interferência da polinização entomófila na produtividade do morangueiro está mais relacionada à redução do percentual de frutos deformados do que ao aumento da massa dos frutos em si. O comportamento de P. nigriceps indica que a espécie apresenta potencial para polinização da cultura do morangueiro em ambiente protegido.

Análise genética de características de crescimento e perímetro escrotal em bovinos da raça Brangus

O objetivo deste trabalho foi estimar os parâmetros genéticos e a tendência genética de características de crescimento e perímetro escrotal em animais da raça Brangus. Dados de 6.340 animais, criados em cinco propriedades nas regiões Sul, Sudeste e Centro‑Oeste do Brasil, foram utilizados para avaliação de: perímetro escrotal (PE) ao sobreano e pesos ao nascer (PN), à desmama (P205), ao ano (P365) e ao sobreano (P550). Os componentes de covariância foram estimados por inferência bayesiana, sob modelo animal, com efeitos fixos de grupos de contemporâneos e de classe de idade da vaca ao parto, e efeitos aleatórios genético aditivo direto e residual. Os efeitos aleatórios genético materno e de ambiente permanente materno foram incluídos somente para PN e P205. O efeito linear da covariável idade do animal na mensuração foi considerado para todas as características analisadas, exceto PN. As médias observadas foram 33,6, 184,6, 235,9, 344,9 e 33,8 cm para PN, P205, P365, P550 e PE, respectivamente, e as tendências genéticas foram de ‑0,001, 0,107, 0,177, 0,217 kg por ano e 0,001 cm por ano. As estimativas das herdabilidades direta e materna variaram de 0,16 (PN) a 0,61 (PE) e de 0,08 (PN) a 0,09 (P205), indicativas de que as características avaliadas são passíveis de seleção para o melhoramento genético da raça Brangus.

Crescimento e produtividade de nogueira-macadâmia em consórcio com cafeeiro arábica irrigado

O objetivo deste trabalho foi avaliar o crescimento e a produtividade de cultivares de nogueira-macadâmia (Macadamia integrifolia), em sistema de cultivo consorciado com café (Coffea arabica) irrigado. O experimento foi realizado em delineamento inteiramente ao acaso, com dez repetições. Seis cultivares de macadâmia foram utilizadas, das quais três nacionais (IAC 4-12B, IAC 4-20 e IAC 9-20) e três havaianas (HAES 344, HAES 660 e HAES 816). Nos quatro primeiros anos de produção, foram feitas avaliações de: altura de planta, diâmetro de copa e de tronco, número de nozes por planta, peso médio de noz, peso médio de amêndoa, produção de nozes por planta, taxa de recuperação e produção de amêndoas por planta. As cultivares nacionais apresentaram menor crescimento em altura, com destaque para IAC 4-20, porém, com copas de maior diâmetro. As cultivares nacionais são mais produtivas, com destaque para a IAC 4-12B.

Selection of bee species for environmental risk assessment of GM cotton in the Brazilian Cerrado

The objective of this work was to list potential candidate bee species for environmental risk assessment (ERA) of genetically modified (GM) cotton and to identify the most suited bee species for this task, according to their abundance and geographical distribution. Field inventories of bee on cotton flowers were performed in the states of Bahia and Mato Grosso, and in Distrito Federal, Brazil. During a 344 hour sampling, 3,470 bees from 74 species were recovered, at eight sites. Apis mellifera dominated the bee assemblages at all sites. Sampling at two sites that received no insecticide application was sufficient to identify the three most common and geographically widespread wild species: Paratrigona lineata, Melissoptila cnecomola, and Trigona spinipes, which could be useful indicators of pollination services in the ERA. Indirect ordination of common wild species revealed that insecticides reduced the number of native bee species and that interannual variation in bee assemblages may be low. Accumulation curves of rare bee species did not saturate, as expected in tropical and megadiverse regions. Species-based approaches are limited to analyze negative impacts of GM cotton on pollinator biological diversity. The accumulation rate of rare bee species, however, may be useful for evaluating possible negative effects of GM cotton on bee diversity.

Neurotrophic activity of human adipose stem cells isolated from deep and superficial layers of abdominal fat.

New approaches to the clinical treatment of traumatic nerve injuries may one day utilize stem cells to enhance nerve regeneration. Adipose-derived stem cells (ASC) are found in abundant quantities and can be harvested by minimally invasive procedures that should facilitate their use in such regenerative applications. We have analyzed the properties of human ASC isolated from the deep and superficial layers of abdominal fat tissue obtained during abdominoplasty procedures. Cells from the superficial layer proliferate significantly faster than those from the deep layer. In both the deep and superficial layers, ASC express the pluripotent stem cell markers oct4 and nanog and also the stro-1 cell surface antigen. Superficial layer ASC induce the significantly enhanced outgrowth of neurite-like processes from neuronal cell lines when compared with that of deep layer cells. However, analysis by reverse transcription with the polymerase chain reaction and by enzyme-linked immunosorbent assay has revealed that ASC isolated from both layers express similar levels of the following neurotrophic factors: nerve growth factor, brain-derived neurotrophic factor and glial-derived neurotrophic factor. Thus, human ASC show promising potential for the treatment of traumatic nerve injuries. In particular, superficial layer ASC warrant further analysis of their neurotrophic molecules.

Analysis of a finite volume method for a cross-diffusion model in population dynamics

The main goal of this paper is to propose a convergent finite volume method for a reactionâeuro"diffusion system with cross-diffusion. First, we sketch an existence proof for a class of cross-diffusion systems. Then the standard two-point finite volume fluxes are used in combination with a nonlinear positivity-preserving approximation of the cross-diffusion coefficients. Existence and uniqueness of the approximate solution are addressed, and it is also shown that the scheme converges to the corresponding weak solution for the studied model. Furthermore, we provide a stability analysis to study pattern-formation phenomena, and we perform two-dimensional numerical examples which exhibit formation of nonuniform spatial patterns. From the simulations it is also found that experimental rates of convergence are slightly below second order. The convergence proof uses two ingredients of interest for various applications, namely the discrete Sobolev embedding inequalities with general boundary conditions and a space-time $L^1$ compactness argument that mimics the compactness lemma due to Kruzhkov. The proofs of these results are given in the Appendix.

Patents in the Information and Communications Technology Sector - Development Trends, Problem Areas and Pressures for Change

The patent system was created for the purpose of promoting innovation by granting the inventors a legally defined right to exclude others in return for public disclosure. Today, patents are being applied and granted in greater numbers than ever, particularly in new areas such as biotechnology and information andcommunications technology (ICT), in which research and development (R&D) investments are also high. At the same time, the patent system has been heavily criticized. It has been claimed that it discourages rather than encourages the introduction of new products and processes, particularly in areas that develop quickly, lack one-product-one-patent correlation, and in which theemergence of patent thickets is characteristic. A further concern, which is particularly acute in the U.S., is the granting of so-called 'bad patents', i.e. patents that do not factually fulfil the patentability criteria. From the perspective of technology-intensive companies, patents could,irrespective of the above, be described as the most significant intellectual property right (IPR), having the potential of being used to protect products and processes from imitation, to limit competitors' freedom-to-operate, to provide such freedom to the company in question, and to exchange ideas with others. In fact, patents define the boundaries of ownership in relation to certain technologies. They may be sold or licensed on their ownor they may be components of all sorts of technology acquisition and licensing arrangements. Moreover, with the possibility of patenting business-method inventions in the U.S., patents are becoming increasingly important for companies basing their businesses on services. The value of patents is dependent on the value of the invention it claims, and how it is commercialized. Thus, most of them are worth very little, and most inventions are not worth patenting: it may be possible to protect them in other ways, and the costs of protection may exceed the benefits. Moreover, instead of making all inventions proprietary and seeking to appropriate as highreturns on investments as possible through patent enforcement, it is sometimes better to allow some of them to be disseminated freely in order to maximize market penetration. In fact, the ideology of openness is well established in the software sector, which has been the breeding ground for the open-source movement, for instance. Furthermore, industries, such as ICT, that benefit from network effects do not shun the idea of setting open standards or opening up their proprietary interfaces to allow everyone todesign products and services that are interoperable with theirs. The problem is that even though patents do not, strictly speaking, prevent access to protected technologies, they have the potential of doing so, and conflicts of interest are not rare. The primary aim of this dissertation is to increase understanding of the dynamics and controversies of the U.S. and European patent systems, with the focus on the ICT sector. The study consists of three parts. The first part introduces the research topic and the overall results of the dissertation. The second part comprises a publication in which academic, political, legal and business developments that concern software and business-method patents are investigated, and contentiousareas are identified. The third part examines the problems with patents and open standards both of which carry significant economic weight inthe ICT sector. Here, the focus is on so-called submarine patents, i.e. patentsthat remain unnoticed during the standardization process and then emerge after the standard has been set. The factors that contribute to the problems are documented and the practical and juridical options for alleviating them are assessed. In total, the dissertation provides a good overview of the challenges and pressures for change the patent system is facing,and of how these challenges are reflected in standard setting.

Competencia de trabajo en equipo: definición y categorización

La competencia de trabajo en equipo se impone a la individualización laboral. El cambio de estructura y proceso de las organizaciones de la sociedad actual ha generado un gran impacto en la nueva manera de trabajar. Las tareas han aumentado su dificultad, haciendo que su resolución individual sea imposible. Es por este motivo, que las organizaciones del trabajo reclaman, hoy más que nunca, la competencia transversal de trabajo en equipo. Este constructo (Competencia de Trabajo en Equipo) recientemente nuevo en las organizaciones ofrece definiciones y modelos de categorización subyacentes que necesitan hacerse oír en el panorama sociolaboral. En esta revisión de la literatura se analizan los 4 modelos más representativos de la competencia de trabajo en equipo, a través de los cuales se propone una definición de la competencia y una posible estructura de la categorización de la misma.

Evaluation of winter temperatures on apple budbreak using grafted twigs

Temperature is the main climate factor related to induction, maintenance and dormancy release in apple (Malus domestica Borkh.). The inadequate chilling exposure in apples causes budbreak problems, resulting in decrease in yield potential. Thus, the knowledge of physiological principles and environmental factors determining the dormancy phenomenon, especially winter temperature effects, it is necessary for the efficient selection of cultivars in a productive region. In addition, it is indispensable to adapt the orchard management aiming to decrease the problems caused by lack chilling during winter. The objective of this study was to evaluate the influence of different thermal conditions during the dormancy period on budbreak of apple cultivars. One-year-old twigs of 'Castel Gala' and 'Royal Gala' cultivars, grafted on M7 rootstock, were submitted to temperatures of 5, 10 and 15ºC for different exposure periods (168; 336; 672; 1,008 and 1,344 hours). After treatments execution, the plants were kept in a greenhouse at 25ºC. Budbreak was quantified when accumulated 3,444; 6,888; 10,332; 13,776; 17,220 and 20,664 GDHºC after temperature treatments. The cultivars responded differently to temperature effect during the winter period. The temperature of 15ºC during winter shows a greater effectiveness on 'Castel Gala' apple budbreak while in the 'Royal Gala' apples the temperatures of 5 and 10ºC show better performance. 'Castel Gala' cultivar (low chilling requirement) may supply its physiological necessities, may be capable to budburst, even when subjected to higher temperatures in relation to 'Royal Gala' apples (high chilling requirement).

La chute comme événement du parcours de vie : signification, conséquences, adaptation et prévention

La chute chez les personnes âgées est considérée comme un problème de santé publique en raison de sa fréquence, de ses conséquences ainsi que de l'efficacité de certain programmes de prévention. La chute est pourtant très souvent non signalée par les personnes ou par les professionnels. Je postule que la chute est un événement traumatisant ; j'examine d'une part son impact sur les trajectoires de personnes à partir de 50 ans et d'autre part l'adaptation à cet événement. Mobilisant différents types de données existantes, ce travail met en évidence les nombreux impacts de la chute au-delà de la santé, et notamment sur les dimensions sociales et sur la qualité de vie ; en comparaison à d'autres événements de santé, la chute présente un effet sur plusieurs indicateurs qui s'exprime tant à court qu'à long terme. J'identifie des facteurs de vulnérabilité à la chute : le moment de survenue de l'événement est un critère déterminant, l'adaptation étant plus difficile quand la chute survient chez des moins de 65 ans ; la gravité de l'événement entrave également la probabilité de s'y adapter. Par contre, les ressources institutionnelles sont sous-utilisées par les personnes concernées et les effets d'un programme généraliste de prévention des chutes fondé sur de l'activité physique et de l'éducation pour la santé sont modestes et ne se maintiennent pas au-delà de l'intervention. Au final, cette thèse apporte une contribution originale à l'étude psychosociale de la chute envisagée au moyen du modèle de la vulnérabilité : ses conclusions permettent d'ajuster des interventions qui devraient prioritairement viser à renforcer les ressources et stratégies individuelles et ensuite à gérer les conséquences identitaires et émotionnelles liées à la chute.

Emergência de plântulas e enraizamento de estacas e alporques de porta-enxertos de nogueira-macadâmia

A nogueira macadâmia apresenta-se como uma importante alternativa para a fruticultura paulista, principalmente pela sua rusticidade e pelo valor alcançado por seus frutos. No entanto, estudos da propagação säo necessários para melhorar o sistema de produção de mudas. Com o objetivo de aumentar a emergência das plântulas, o enraizamento de estacas e a produção de alporques de porta-enxertos da nogueira- macadâmia, conduziram-se diferentes experimentos: emergência de plântulas de oito cultivares de nogueira-macadâmia ('HAES-344', 'HAES-660', 'IAC 1-21', 'HAES-816', 'IAC 4-20', 'IAC Campinas - B', 'Aloha' e 'IAC 4-12-B'); emergência de plântulas do porta-enxerto de nogueira-macadâmia 'Aloha' em diferentes temperaturas no substrato (23; 25; 27; 29 e 31ºC); enraizamento de diferentes tipos de estacas do porta-enxerto de nogueira-macadâmia 'Aloha' (estacas com uma folha inteira, duas folhas inteiras, uma folha reduzida e duas folhas reduzidas), tratadas com ou sem ácido indolbutírico (3.000 mg L-1) por 10 seg.; alporquia em ramos de nogueira-macadâmia 'Aloha', realizada em diferentes épocas (agosto, dezembro e abril) e tratadas com diferentes concentrações de ácido indolbutírico (0; 3.000;6.000 e 9.000 mg L-1 por 10 seg.). Os resultados mostraram que a maior massa da matéria seca da parte aérea e do sistema radicular foi obtida com a cultivar Aloha; a maior emergência de plântulas foi obtida com a temperatura de 27 ºC; a maior porcentagem de enraizamento foi obtida em estacas com duas folhas inteiras e tratadas com AIB; os melhores resultados para a alporquia da cultivar Aloha foram obtidos em dezembro, sem o tratamento com AIB.
