Efeito imediato do método de secagem na qualidade de sementes de crambe

Crambe (Crambe abyssinica Hochst) seeds have high oil contents and its growth in Brazil aims to produce bio diesel. The crambe seeds production and commercialization began a few years ago. Research in technology production is essential and it is also important to use high quality seeds regardless of the technological level employed in the crop production. One of the factors that affect seed quality there is the drying process. Seed drying performed properly can reduce seed moisture content for storage without decrease in its qualitative characteristics. The aim of this study was to evaluate the immediate effect of natural and artificial drying methods (using heated and unheated air) on crambe seeds quality. The seeds were produced at Fazenda Lageado, Faculdade de Ciências Agronômicas, UNESP, Botucatu/SP, on April 2009. Seeds were submitted to the following drying methods: a) seed drying in the shade with natural ventilation; b) artificial drying method using heated air; c) artificial drying method using unheated air; d) drying on ceramic patio; e) drying on the mother plant. The seeds were evaluated immediately after drying. The following tests were performed: seed moisture content; standard germination; first count of germination; seedling emergence; emergence speed index and electrical conductivity. The experimental design was randomized blocks and the data obtained was subjected to analysis of variance, worth means being compared by Tukey test at 5% probability. There was no significant difference among drying treatments in relation to: germination rate, first count of germination, electrical conductivity, seedling emergence and emergence speed index. The highest percentage of abnormal seedlings was obtained on treatment with heated air drying. The drying on the mother plant method showed the lower percentage of dead seeds. The drying methods studied did not cause an immediate effect on crambe seeds quality, which showed high percentage of dormant seeds post-harvest.

O valor econômico da extração manejada de madeira no baixo Amazonas, estado do Pará

O objetivo deste trabalho foi estimar o valor econômico e a margem de comercialização da madeira em tora oriunda de áreas manejadas. Essa cadeia, além de produzir margem positiva, os valores são relativamente superiores aos gerados nas atividades que concorrem para o desmatamento na Amazônia para se estabelecerem. Adicionalmente, determinou-se o coeficiente médio de desdobramento de 37,3% (2,68 m³ de madeira em tora para cada 1,0 m³ de madeira serrada), o qual revelou baixo grau tecnológico das empresas. O valor econômico médio da extração e comercialização da madeira em pé no mercado local foi de R$ 23,48/m³, tendo um valor mínimo de R$ 9,06/m³ para as espécies da categoria C4 (madeira branca) e um máximo de R$ 55,63/m³ para as espécies da categoria C1 (madeira especial). Assim, para um fluxo de 30 anos e extração de 25 m³/ha nos planos de manejo das áreas de concessão florestal do Estado do Pará, gera-se um valor médio de R$ 587,00/ha, ou R$ 19,56/ha/ano. No fluxo de 30 anos, esse resultado é relativamente superior ao gerado pelas atividades de pecuária extensiva (em torno de R$ 180,00/ha) e das lavouras de grãos (em torno dos R$ 420,00/ha), principais responsáveis pelo desmatamento da Amazônia. Também, apresenta maior rentabilidade do que o reflorestamento com paricá, que gera R$ 192,26/ha. A margem de comercialização indicou que a sociedade tende a se apropriar de 14,3% do valor econômico gerado na cadeia da madeira oriunda dos contratos de concessão florestal.

El nuevo escenario global y un modelo de negocio para la industria naval militar del 2025

Los retos y oportunidades a los que se enfrentan las organizaciones y administraciones de las primeras décadas del siglo XXI se caracterizan por una serie de fuerzas perturbadoras como la globalización, el avance de las tecnologías emergentes y el desequilibrio económico, que están actuando como impulsores de la transformación del mercado. La acción conjunta de estos factores está obligando a todas las empresas industriales a tener que trabajar con mayores y más exigentes niveles de productividad planteándose continuamente como mejorar y lograr satisfacer los requerimientos de los clientes. De esta situación surge la necesidad de volver a plantearse de nuevo ¿quién es el cliente?, ¿qué valora el cliente? y ¿cómo se pueden generan beneficios sostenibles? La aplicación de esta reflexión a la industria naval militar marca los objetivos a los que esta tesis doctoral busca dar respuesta. El primer objetivo, de carácter general, consiste en la definición de un modelo de negocio sostenible para la industria naval militar del 2025 que se adapte a los requisitos del cliente y al nuevo escenario político, económico, social, tecnológico y ambiental que rodea esta industria. El segundo objetivo, consecuencia del modelo general, trata de desarrollar una metodología para ejecutar programas de apoyo al ciclo de vida del “buque militar”. La investigación se estructura en cuatro partes: en la primera se justifica, por un lado, la necesidad del cambio de modelo y por otro se identifican los factores estructurantes para la definición del modelo. La segunda parte revisa la literatura existente sobre uno de los aspectos básicos para el nuevo modelo, el concepto Producto-Servicio. La tercera parte se centra totalmente en la industria naval militar estudiando los aspectos concretos del sector y, en base al trabajo de campo realizado, se identifican los puntos que más valoran las Marinas de Guerra y como estas gestionan al buque militar durante todo su ciclo de vida. Por último se presentan los principios del modelo propuesto y se desarrollan los pilares básicos para la ejecución de proyectos de Apoyo al Ciclo de Vida (ACV). Como resultado de la investigación, el modelo propuesto para la industria naval militar se fundamenta en once principios: 1. El buque militar (producto de alto valor añadido) debe ser diseñado y construido en un astillero del país que desarrolla el programa de defensa. 2. El diseño tiene que estar orientado al valor para el cliente, es decir, se tiene que diseñar el buque militar para que cumpla su misión, eficaz y eficientemente, durante toda su vida operativa, asegurando la seguridad del buque y de las personas y protegiendo el medio ambiente de acuerdo con las regulaciones vigentes. 3. La empresa debe suministrar soluciones integrales de apoyo al ciclo de vida al producto. 4. Desarrollar y mantener las capacidades de integración de sistemas complejos para todo el ciclo de vida del buque militar. 5. Incorporar las tecnologías digitales al producto, a los procesos, a las personas y al propio modelo de negocio. 6. Desarrollar planes de actuación con el cliente domestico a largo plazo. Estos planes tienen que estar basados en tres premisas: (i) deben incluir el ciclo de vida completo, desde la fase de investigación y desarrollo hasta la retirada del buque del servicio; (ii) la demanda debe ser sofisticada, es decir las exigencias del cliente, tanto desde la óptica de producto como de eficiencia, “tiran” del contratista y (iii) permitir el mantenimiento del nivel tecnológico y de las capacidades industriales de la compañía a futuro y posicionarla para que pueda competir en el mercado de exportación. 7. Impulsar el sector militar de exportación mediante una mayor actividad comercial a nivel internacional. 8. Fomentar la multilocalización ya que representa una oportunidad de crecimiento y favorece la exportación posibilitando el suministro de soluciones integrales en el país destino. 9. Reforzar la diplomacia institucional como palanca para la exportación. 10. Potenciar el liderazgo tecnológico tanto en producto como en procesos con políticas activas de I + D+ i. 11. Reforzar la capacidad de financiación con soluciones innovadoras. El segundo objetivo de esta tesis se centra en el desarrollo de soluciones integrales de Apoyo al Ciclo de Vida (ACV). La metodología planteada trata de minimizar la brecha entre capacidades y necesidades a lo largo de la vida operativa del barco. Es decir, el objetivo principal de los programas de ACV es que la unidad conserve durante toda su vida operativa, en términos relativos a las tecnologías existentes, las capacidades equivalentes a las que tendrá cuando entre en servicio. Los ejes de actuación para conseguir que un programa de Apoyo al Ciclo de Vida cumpla su objetivo son: el diseño orientado al valor, la ingeniería de Apoyo al Ciclo de Vida, los proyectos de refresco de tecnología, el mantenimiento Inteligente y los contratos basados en prestaciones. ABSTRACT On the first decades of the 21st century, organizations and administrations face challenges and come across opportunities threatened by a number of disruptive forces such as globalization, the ever-changing emerging technologies and the economic imbalances acting as drivers of the market transformation. This combination of factors is forcing all industrial companies to have more and higher demanding productivity levels, while bearing always in mind how to improve and meet the customer’s requirements. In this situation, we need to question ourselves again: Who is the customer? What does the customer value? And how can we deliver sustainable economic benefits? Considering this matter in a military naval industry framework sets the goals that this thesis intends to achieve. The first general goal is the definition of a new sustainable business model for the 2025 naval industry, adapted to the customer requirements and the new political, economic, social, technological and environmental scenario. And the second goal that arises as a consequence of the general model develops a methodology to implement “warship” through life support programs. The research is divided in four parts: the first one justifies, on the one hand, the need to change the existing model and, on the other, identifies the model structural factors. On the second part, current literature regarding one of the key issues on the new model (the Product-Service concept) is reviewed. Based on field research, the third part focuses entirely on military shipbuilding, analyzing specific key aspects of this field and identifying which of them are valued the most by Navies and how they manage through life cycles of warships. Finally, the foundation of the proposed model is presented and also the basic grounds for implementing a Through Life Support (TLS) program are developed. As a result of this research, the proposed model for the naval industry is based on eleven (11) key principles: 1. The warship (a high added value product) must be designed and built in a shipyard at the country developing the defense program. 2. Design must be customer value oriented, i.e.warship must be designed to effectively fulfill its mission throughout its operational life, ensuring safety at the ship and for the people and protecting the environment in accordance with current regulations. 3. The industry has to provide integrated Through Life Support solutions. 4. Develop and maintain integrated complex systems capabilities for the entire warship life cycle. 5. Introduce the product, processes, people and business model itself to digital technologies. 6. Develop long-term action plans with the domestic customer. These plans must be based on three premises: (i) the complete life cycle must be included, starting from the research and development stage throughout the ship’s disposal; (ii) customer demand has to be sophisticated, i.e. customer requirements, both from the efficiency and product perspective, "attract" the contractor and (iii) technological level and manufacturing capabilities of the company in the future must be maintained and a competitive position on the export market has to be achieved. 7. Promote the military exporting sector through increased international business. 8. Develop contractor multi-location as it entails an opportunity for growth and promote export opportunities providing integrated solutions in the customer's country. 9. Strengthen institutional diplomacy as a lever for export. 10. Promote technological leadership in both product and processes with active R & D & I policies (Research & Development & Innovation) 11. Strengthen financing capacity through innovative solutions. The second goal of this thesis is focused on developing integrated Through Life Support (TLS) solutions. The proposed methodology tries to minimize the gap between needs and capabilities through the ship operational life. It means, the main TLS program objective is to maintain the ship’s performance and capabilities during operational life, in relative terms to current technologies, equivalent to those the ship had when it entered service. The main actions to fulfill the TLS program objectives are: value-oriented design, TLS engineering, technology updating projects, intelligent maintenance and performance based contracts.

Intellectual Communications and Contemporarly Technologies Alternatives of the Science Libraries

(Summary of: Varbanova-Dencheva, K. Intellectual communications and contemporarly technologies. Alternatives of the science libraries. Sofia, Marin Drinov academic publishing house. 2003, 114p. ) The new technologies and the globalization are the factors which have brought essential changes in human society and its environment. The unceasing dynamic changes imposed new strategies for survival and prosperity of institutions and people in the new conditions. The spheres with greatest potential for achieving competition priority are compatible to the fastness of research results implementation in each field of human activity. The extended knowledge requires narrower specialization as well as interdisciplinarity to solve the arising problems. The new research fields and trends are a synthesis of science and high technologies determined by the new discoveries. The present study aims at finding answers to the questions about the place of science library in the dynamic restructuring of research environment. The necessity of transformation of the scientific library’s genetically set functions from a guardian of the achieved knowledge to an active participant in the creation of new knowledge is a natural consequence of the processes and tendencies of the social medium. The priorities of Europe and USA for intensive creation of knowledge economics are at the first place and this requires intensification of that research an integral part of which are the new communications realized at a new technological level.

A tractable means of correcting sector level TFP calculations in the face of biased technological change.

The measurement of the impact of technical change has received significant attention within the economics literature. One popular method of quantifying the impact of technical change is the use of growth accounting index numbers. However, in a recent article Nelson and Pack (1999) criticise the use of such index numbers in situations where technical change is likely to be biased in favour of one or other inputs. In particular they criticise the common approach of applying observed cost shares, as proxies for partial output elasticities, to weight the change in quantities which they claim is only valid under Hicks neutrality. Recent advances in the measurement of product and factor biases of technical change developed by Balcombe et al (2000) provide a relatively straight-forward means of correcting product and factor shares in the face of biased technical progress. This paper demonstrates the correction of both revenue and cost shares used in the construction of a TFP index for UK agriculture over the period 1953 to 2000 using both revenue and cost function share equations appended with stochastic latent variables to capture the bias effect. Technical progress is shown to be biased between both individual input and output groups. Output and input quantity aggregates are then constructed using both observed and corrected share weights and the resulting TFPs are compared. There does appear to be some significant bias in TFP if the effect of biased technical progress is not taken into account when constructing the weights

Mean sea-level rise impacts on Santos Bay, Southeastern Brazil - physical modelling study

The greenhouse effect and resulting increase in the Earth`s temperature may accelerate the mean sea-level rise. The natural response of bays and estuaries to this rise, such as this case study of Santos Bay (Brazil), will include change in shoreline position, land flooding and wetlands impacts. The main impacts of this scenario were studied in a physical model built in the Coastal and Harbour Division of Hydraulic Laboratory, University of Sao Paulo, and the main conclusions are presented in this paper. The model reproduces near 1,000 km(2) of the study area, including Santos, Sao Vicente, Praia Grande, Cubatao, Guaruja and Bertioga cities.

Cytokine Signatures of Innate and Adaptive Immunity in 17DD Yellow Fever Vaccinated Children and Its Association With the Level of Neutralizing Antibody

Background. The live attenuated yellow fever (YF) vaccines have been available for decades and are considered highly effective and one of the safest vaccines worldwide. Methods. The impact of YF-17DD-antigens recall on cytokine profiles of YF-17DD-vaccinated children were characterized using short-term cultures of whole blood samples and single-cell flow cytometry. This study enrolled seroconverters and nonseroconverters after primovaccination (PV-PRNT(+) and PV-PRNT(-)), seroconverters after revaccination (RV-PRNT(+)), and unvaccinated volunteers (UV-PRNT(-)). Results. The analysis demonstrated in the PV-PRNT(+) group a balanced involvement of pro-inflammatory/regulatory adaptive immunity with a prominent participation of innate immunity pro-inflammatory events (IL-12(+) and TNF-alpha(+) NEU and MON). Using the PV-PRNT(+) cytokine signature as a reference profile, PV-PRNT(+) presented a striking lack of innate immunity proinflammatory response along with an increased adaptive regulatory profile (IL-4(+) CD4(+) T cells and IL-10(+) and IL-5(+) CD8(+) T cells). Conversely, the RV-PRNT(+) shifted the overall cytokine signatures toward an innate immunity pro-inflammatory profile and restored the adaptive regulatory response. Conclusions. The data demonstrated that the overall cytokine signature was associated with the levels of PRNT antibodies with a balanced innate/adaptive immunity with proinflammatory/regulatory profile as the hallmark of PV-PRNT(MEDIUM+), whereas a polarized regulatory response was observed in PV-PRNT(-) and a prominent proinflammatory signature was the characteristic of PV-PRNT(HIGH+).

Educational characteristics of adult students in portuguese technological schools

Despite a massive expansion of education in Portugal, since the 1970’s, educational attainment of the adult population in the country remains low. The numbers of working-age people in some form of continuing education are among the lowest, according to the OECD and EU-27 statistics. Technological Schools(TS), initially created in the 1990’s, under the umbrella of the Ministry of Economy in partnership with industry and industrial associations, aimed to prepare qualified staff for industries and services in the country, particularly in the engineering sector, through the provision of post secondary non-university programmes of studies, the CET (Technological Specialization Courses). Successful CET students are awarded a DET(Diploma of Technological Specialization), which corresponds to Vocational Qualification level IV of the EU, according to the latest alteration (2005) of the Education Systems Act (introduced in 1986). In this, CET’s are also clearly defined as one of the routes for access to Higher Education (HE), in Portugal. The PRILHE (Promoting Reflective and Independent Learning in Higher Education) multinational project, funded by the European Socrates Grundtvig Programme, aimed to identify the learning processes which enable adult students in higher education to become autonomous reflective learners and search best practices to support these learning processes. During this research, both quantitative and qualitative methods were used to determine how students organise their studies and develop their learning skills. The Portuguese partner in the project’ consortium used a two case studies approach, one with students of Higher Education Institutions and other with students of TS. This paper only applies to students of TS, as these have a predominant bias towards engineering. Results show that student motivation and professional teaching support contribute equally to the development of an autonomous and reflective approach to learning in adult students; this is essential for success in a knowledge economy, where lifelong learning is the key to continuous employment.
