    Mental health reform in Brazil presupposes mental health becoming integrated into the Brazilian health system, involving multidisciplinary teams whose professional practice has yet to be defined. The present study forms part of a project aimed at understanding human resources practices in Brazilian mental healthcare services. This was a descriptive, exploratory study using a sample of highly qualified practitioners involved in the Ribeirao Preto/SP public mental health network. The project was approved by the Ribeirao Preto College of Nursing/University of Sao Paulo's ethics committee. A semi-structured questionnaire was used and the data was statistically analyzed. One hundred and forty-four of the 193 practitioners from the 8 public mental and psychiatric health care services agreed to participate. It was observed that current practice was mainly based on individual care, emphasizing medical, psychological and nursing care. Group activities were more frequently provided by community services. Mental care was infrequently prescribed and a low value was placed on activities like observation, recording and therapeutic interaction. Mental care services were being structured; however, practitioners still had difficulties in implementing current policy.

    Full Text Available The aim of this study was to evaluate methods for developing a Brazilian maize core collection. For an initial survey of the active collection, passport information, as well as characterization and evaluation of accessions, were taken into consideration, these then being divided according to geographic region and kernel-type. Multiple sampling methods were evaluated. The strategy of constant sampling generated extensive alterations in extract accession frequency. The multivariate strategy with dispersion graphs and principal components associated with the Tocher method was considered efficient for identifying the most divergent genotypes. The multivariate strategy generated greater alterations in the variance of traits. The average number of traits revealed few modifications with the various sampling strategies used. Therefore, the active collection could be considered as possessing a satisfactory amount of information for most of its accessions. Moreover, the multivariate strategy generated modifications in the variance of the traits, independent of sampling intensity.

    Full Text Available Microsatellite markers, also known as SSRs (Simple Sequence Repeats, have proved to be excellent tools for identifying variety and determining genetic relationships. A set of 127 SSR markers was used to analyze genetic similarity in twenty five Coffea arabica varieties. These were composed of nineteen commercially important Brazilians and six interspecific hybrids of Coffea arabica, Coffea canephora and Coffea liberica. The set used comprised 52 newly developed SSR markers derived from microsatellite enriched libraries, 56 designed on the basis of coffee SSR sequences available from public databases, 6 already published, and 13 universal chloroplast microsatellite markers. Only 22 were polymorphic, these detecting 2-7 alleles per marker, an average of 2.5. Based on the banding patterns generated by polymorphic SSR loci, the set of twenty-five coffee varieties were clustered into two main groups, one composed of only Brazilian varieties, and the other of interspecific hybrids, with a few Brazilians. Color mutants could not be separated. Clustering was in accordance with material genealogy thereby revealing high similarity.

    2011-07-01

    Full Text Available The globalization phenomenon has given rise to a new and virtually limitless dimension for companies to gain access to new markets beyond their country borders. This has proven to be an opportunity for growth and expansion. Given the transformations that this phenomenon has driven in the international business environment, one is struck by the fact that the presence of Brazilian companies abroad is still low, as Brazilian business is continues to be shy of expanding via internationalization. One concludes that the leaders of Brazilian firms are better prepared to operate in the domestic market and with processes and businesses that focus on exports; few executives are required to run operations abroad. However, the reality of internationalization calls for a new type of manager, the “global executive,” who is expected to be cosmopolitan, a negotiator and a cross-culture communicator that is able to generate synergy and lead changes. Brazilian companies that want to grow beyond cultural and ethnic frontiers are facing the challenge of forming theses “citizens of the world,” capable not only of making room in the international market, but also of leading the processes of transformation and change within corporate environments. The aim of this article is to discuss how to develop people for the strategic management of internationalization processes, as well as to identify current gaps and to provide recommendations both for the development of the competences that a global mindset requires among our managers, and for the management of the international mobility of Brazilian executives.Key words: Company internationalization. Expatriation. People management. Leadership.

    The Plasma Physics Laboratory (PPLUnB) has been developing a Permanent Magnet Hall Thruster (PHALL) for the Space Research Program for Universities (UNIESPAÇO), part of the Brazilian Space Activities Program (PNAE) since 2004. The PHALL project consists on a plasma source design, construction and characterization of the Hall type that will function as a plasma propulsion engine and characterized by several plasma diagnostics sensors. PHALL is based on a plasma source in which a Hall current is generated inside a cylindrical annular channel with an axial electric field produced by a ring anode and a radial magnetic field produced by permanent magnets. In this work it is shown a brief description of the plasma propulsion engine, its diagnostics instrumentation and possible applications of PHALL on orbit transfer maneuvering for future Brazilian geostationary satellite space missions.

  12. Path Dependence and Institutional Change in Brazilian Development

    2015-06-01

    Full Text Available The left turn in Latin American politics has been associated to a new consensus over the role of the state in fostering development. Brazil historically stands as one of the most socially and economically unequal countries in the world. However, data on poverty reduction and social mobility in the country in the last decade have brought back the recognition of Brazilian government's ability to conduct a development process, which was strongly questioned since the fiscal crisis of the 80s. Drawing on the literature of path dependency and institutional change, the paper presents an analysis of these changes, focusing on the central question: to what extent the rise of a left-wing party to power and mentioned changes represent a break with the legacy of institutional development of the country and to what extent are them conditioned by this legacy?

    Full Text Available Historical epistemology has played an important role in the development of modern Brazilian Public Health or “Saúde Coletiva” (Collective Health. Born as an academic search for new conceptual foundations of a social committed field of scientific knowledge, as well as a social political movement against civil-military dictatorship implanted in Brazil in 1964, the so called Brazilian Sanitary Reform Movement found in the French historical epistemology, particularly in the works of Georges Canguilhem, a powerful ally. This paper aims to revisit the main features of this relationship, focusing in particular the inaugural works of Sergio Arouca and Cecília Donnangelo and the Health Work Process Theory as developed in the Department of Preventive Medicine of the Medical School of the University of São Paulo. The discussion is centered in the way Canguilhem’s philosophical concepts, such as the normative character of life and of its knowledge, the qualitative discontinuity between normal and pathological phenomena and the value oriented definition of health on one hand, and on the other hand, Canguilhem’s historiographical method, focused on the rational development of concepts as the core subject of the historical-epistemological research, the acknowledge of “external” influences over scientific developments, such as social and technological conditions, and the positive role attributed to obstacles, failures and accidents in the progress of a scientific discipline were all crucial to promote the intertwining of the political and academic goals of the Movement and still remain a challenging element for the development of the philosophical and historical reflections of the field of “Saúde Coletiva”.

    Full Text Available Dissociated motor development (DMD is considered when the baby starts independent walking late, with normality of the other fields of development. There is evidence that babies with DMD present an atypical crawling pattern and hypotonia. To investigate the frequency and characteristics of DMD, neurological examination was performed monthly in 177 healthy full-term babies from 6 months age, in urban and rural zone samples in Brazil. Among 20 children with atypical crawling, none presented hypotonia neither did they start independent walking late. The means of the ages at the begining of atypical crawling and independent walking acquisitions, 7.40mo (SD 1.4 and 12.76mo (SD 2.5 respectively, did not differ from the group with crossed crawling pattern. Thus, in this sample of Brazilian healthy children we did not find cases with DMD.

    2007-08-01

    The primary goal of the BRAVO project is to generate investment in information technology, with particular emphasis on datamining and statistical analysis. From a scientific standpoint, the participants assembled to date are engaged in several scientific projects in various fields of cosmology, astrophysics, and data analysis, with significant contributions from international partners. These scientists conduct research on clusters of galaxies, small groups of galaxies, elliptical galaxies, population synthesis, N-body simulations, and a variety of studies in stellar astrophysics. One of the main aspects of this project is the incorporation of these disparate areas of astrophysical research within the context of the coherent development of database technology.Observational cosmology is one of the branches of science experiencing the largest growth in the past few decades. large photometric and spectroscopic surveys have been carried out in both hemispheres. As a result, an extraordinary amount of data in all portions of the electromagnetic spectrum exists, but without standard techniques for storage and distribution. This project will utilize several specific astronomical databases, created to store data generated by several instruments (including SOAR, Gemini, BDA, etc), uniting them within a common framework and with standard interfaces. We are inviting members of the entire Brazilian astronomical community to partake in this effort. This will certainly impact both education and outreach efforts, as well as the future development of astrophysical research. Finally, this project will provide a constant investment in human resources. First, it will do so by stimulating ongoing short technical visits to Johns Hopkins University and Caltech. These will allow us to bring software technology and expertise in datamining back to Brazil. Second, we will organize the Summer School on Software Technology in Astrophysics, which will be designed to ensure that the Brazilian

    Japanese-Brazilians were the third largest immigrant group in Japan in 2011. Their health issues have caused concern, as their limited language made them vulnerable by hindering access to health services. Upon considering child health, mothers' health literacy (HL) is very important. This study aimed to develop a health literacy scale among Brazilian mothers (HLSBM) in Japan. Questionnaires in Portuguese were distributed to 1474 mothers from December 2011 to March 2012. Among 698 collected, 558 questionnaires were analyzed. We prepared 29 candidate items for HLSBM based on Nutbeam's concept of functional, interactive and critical literacy. The dimensional structure was determined statistically using confirmatory factor analysis. Validity was also analyzed by Pearson's correlation with Ishikawa's scale and Kendall's coefficient of concordance among researchers. Cronbach's α coefficients were calculated to examine internal consistency. The confirmatory factor analysis revealed a two-factor model (five items for basic literacy and five items for critical literacy) with sufficient goodness of fit (GFI 969, AGFI 945, NFI 959, CFI 972, RMSEA 060). The internal consistency values of the total score, basic and critical literacy sub-scales were 0.819, 0.889 and 0.667, respectively. Kendall's coefficient of concordance showed good agreement of researchers (p literacy and 0.472 for critical literacy. The HLSBM consisting of two factors was confirmed to be valid and reliable. The HLSBM must be useful for understanding this vulnerable group's health literacy and its associated factors. © The Author 2016. Published by Oxford University Press. All rights reserved.

    Full Text Available In Brazil, the main program with respect to biodiesel is the National Program of Biodiesel Production and Use (NPBP. It is also considered the regulation mark of biodiesel production in Brazil and its directives are social inclusion and regional development. Considering these directives, this paper aims to analyse the perspective of biodiesel sector stakeholders in Brazil to understand whether NPBP directives are in consonance with the reality of the sector for its development. A questionnaire was created with 48 questions in order to understand the importance of 13 variables for the stakeholders, and the responses were treated by factor analysis (FA. The results showed the existence of a trade-off related to technological advances in biodiesel production that confronts NPBP directives, that is, the biodiesel sector tends not to evolve in terms of the use of advanced technologies. If policies change so as to develop the biodiesel sector using advanced technologies, NPBP should change its directives in order to involve family farmers in another way in the Brazilian economy.

    Full Text Available Abstract Introduction: The Hayling Test assesses the components of initiation, inhibition, cognitive flexibility and verbal speed by means of a sentence completion task. This study presents the process of developing the Brazilian version of the Child Hayling Test (CHT and reports evidence of its content validity. Methods: 139 people took part in the study. The adaptation was performed by seven translators and 12 specialist judges. An initial sample of 92 healthy children was recruited to test a selection of sentences adapted from previous adult and pediatric versions of the instrument, and a sample of 28 healthy children was recruited for pilot testing of the final version. The instrument was developed in seven stages: 1 translation, 2 back-translation, 3 comparison of translated versions, 4 preparation of new stimuli, 5 data collection with healthy children to analyze comprehension of the stimuli and analyses by the authors against the psycholinguistic criteria adopted, 6 analyses conducted by judges who are specialists in neuropsychology or linguistics, and 7 the pilot study. Results: Twenty-four of the 72 sentences constructed were selected on the basis of 70-100% agreement between judges evaluating what they assessed and level of comprehensibility. The pilot study revealed better performance by older children, providing evidence of the instrument's sensitivity to developmental factors. Conclusions: Future studies employing this version of CHT with clinical pediatric populations who have frontal lesions and dysfunctions and in related areas are needed to test functional and differential diagnoses of preserved or impaired executive functions.

  20. Cooperation for Development, Brazilian Regional Leadership and Global Protagonism

    2014-08-01

    Full Text Available This article aims to analyze Brazil’s policy towards South America during Luiz Inácio "Lula" da Silva’s government by discussing what kind of leadership the country was able to perform in the region during this time. The authors examine the role played by the policy of International Cooperation for Development on such regional leadership. The central argument is that although Brazil has performed the role of a regional leader, there is a need for distinguishing leadership for regional matters – inwards regional leadership – from leadership for global issues – outwards regional leadership. We argue that inwards regional leadership was in fact successfully performed by Brazil in South America, mainly due to its role as a Development Leader. On the other hand, we also verified that such leadership for regional matters did not always allow Brazil to act on behalf of the entire region on the global arena. Nevertheless, we argue that Brazilian diplomacy left behind the belief that, in order to have global protagonism, the country should use South America as a regional launching platform. Instead, Brazil has been making use of global coalitions such as IBSA and BRICS to boost its global role.

    The use of renewable alternative sources of energy in the world has been growing in the last few decades due to concerns about dependence on fossil sources and to environmental reasons, related to climatic change and its effects on mankind. Tax and/or financial incentives have been instituted for the population, to have access to renewable source technologies, and for the local equipment industry, to develop more quickly. In Brazil, the PV (photovoltaic) equipment to convert solar into electricity is more often used in low income rural communities, located distant from the grid network. However, since there is no currently specific regulatory incentive mechanism for this source in the country, the Brazilian PV equipment industry has not made great advances and the market is largely dominated by multinationals. Against this background, this work has as objective to analyze the current PV equipment industry in Brazil, in such way that the obtained information can aid in a future elaboration of a national program development to promote the use of this technology, stimulating the domestic industry and reducing the dependence on imported equipment.

    The present study evaluates how five sectors of two Brazilian hospitals have implemented lean healthcare concepts in their operations. The main characteristics of the implementation process are analyzed in the present study: the motivational factor for implementation, implementation time, form (consultancy or internal), team (hospital and consultants), lean implementation continuity/sustainability, lean healthcare tools and methods implemented, problems/improvement opportunities, lean healthcare barriers faced during the implementation process, and critical factors that affected the implementation and the results obtained in each case. The case studies indicate that reducing patient lead times and costs and making financial improvements were the primary factors that motivated lean healthcare implementation in the hospitals studied. Several tools and methods were used in the cases studied, especially value stream mapping and DMAIC. The barriers found in both hospitals are primarily associated with the human factor. Additionally, the results obtained after implementation were analyzed and improvements in financial aspects, productivity and capacity, and lead time reduction of the analyzed sectors were observed. Further, this study also exhibited four propositions elaborated from the results obtained from the cases that highlighted barriers and challenges to lean healthcare implementation in developing countries. Two of these barriers are hospital organizational structure (and, consequently, how the senior management works with medical staff), and outsourcing hospital activities. This study also concluded that the initialization and maintenance of lean healthcare implementation rely heavily on external support because lean healthcare subject knowledge is not yet available in the healthcare organization, which represents a challenge.

    In countries with endemic Chagas disease, coinfection involving Trypanosoma cruzi and HIV is expected to become more frequent. There is a clear need to structure a comprehensive care network aimed at dealing with this situation, with mobilization going from primary care to care at the highest level of technological complexity. The objective of this study was to describe the Brazilian response to the challenges of Chagas disease: the history, current issues, and future of the Brazilian Network for attending and studying T. cruzi/HIV coinfection. This descriptive study reviewed technical documents relating to the basis and structuring process of the Brazilian network for attending and studying T. cruzi/HIV coinfection. The process of setting up the network was marked by technical and political debates in technical-scientific meetings going back to the 1990s. This process made it possible to expand and focus on different aspects of comprehensive care for Chagas disease in Brazil, regardless of the associated immunosuppressive conditions. These meetings produced a structure of national technical guidelines and standards, health care and research protocols and research priorities, along with mobilization and awareness-raising among HIV/AIDS reference centers regarding occurrences of coinfection. The creation of the Brazilian network was a milestone for the country in terms of integration of control programs, with the reference point of quality of care and comprehensiveness. The possibility of extending this network to form a Latin American network is seen as a strategy for dealing more effectively with this condition.

    Recommended practice is to verify the gain and/or output of hearing aids with speech or speech-shaped signals. This study has the purpose of developing a speech test signal in Brazilian Portuguese that is electroacoustically similar to the international long-term average speech spectrum (ILTASS) for use in real ear verification systems. A Brazilian Portuguese speech passage was recorded using standardized equipment and procedures for one female talker and compared to ISTS. The passage consisted of simple, declarative sentences making a total of 148 words. The recordings of a Brazilian Portuguese passage were filtered to the ILTASS and compared to the International Speech Test Signal (ISTS). Aided recordings were made at three test levels, for three audiograms for the Brazilian Portuguese passage and the ISTS. The unaided test signals were spectrally matched to within 0.5 dB. Aided evaluation revealed that the Brazilian Portuguese passage produced aided spectra that were within 1 dB on average, within about 2 dB per audiogram, and within about 3 dB per frequency for 95% of fittings. Results indicate that the Brazilian Portuguese passage developed in this study provides similar electroacoustic hearing-aid evaluations to those expected from the standard ISTS passage.

    The review gives data on the history of smallpox vaccination and shows the high topicality of designing the current safe vaccines against orthopoxviruses. Four generations of live smallpox, protein subunit, and DNA vaccines are considered. Analysis of the data published leads to the conclusion that it is promising to use the up-to-date generations of safe smallpox subunit or DNA vaccines for mass primary immunization with possible further revaccination with classical live vaccine.

    2010-01-01

    In recent years, canine genetics had made huge progress. In 1999 the first complete karyotype and ideogram of the dog was published. Several linkage and RH maps followed. Using these maps, sets of microsatellite markers for whole genome scans were compiled. In 2003 the sequencing of the DNA of a female Boxer began. Now the second version of the dog genome assembly has been put online, and recently, a microchip SNP array became available. Parallel to these developments, some causal mutations for different traits have been identified. Most of the identified mutations were responsible for monogenic canine hereditary diseases. With the tools available now, it is possible to use the advantages of the population structure of the various dog breeds to unravel complex genetic traits. Furthermore, the dog is a suitable model for the research of a large number of human hereditary diseases and particularly for cancer genetics, heart and neurodegenerative diseases. There are some examples where it was possible to benefit from the knowledge of canine genetics for human research. The search for quantitative trait loci (QTL), the testing of candidate genes and genome-wide association studies can now be performed in dogs. QTL for skeletal size variations and for canine hip dysplasia have been already identified and for these complex traits the responsible genes and their possible interactions can now be identified.

We assume that such theoretical foundation helps us understand some aspects of the redesign of higher education underway in Brazil conducted by governments Lula da Silva and Dilma Rousseff, particularly the Program of Support to the Restructuring and Expansion of Federal Universities (REUNI. Thus, presenting some data expansion in the two largest public universities in the state of Rio de Janeiro in order to demonstrate the extent to which this process is indicating the precariousness / intensification of teaching and a deep reconfiguration of Brazilian public university.

    Biofuels represent an opportunity for domestic fuel production from renewable energy sources with potential environmental and social benefits such as reducing greenhouse gas (GHG) and promoting rural development. However, as demand for biofuel continues to increase worldwide, concerns about land competition between food and fuel, excessive water usage and other unintended environmental consequences have grown. Through a comparative study between US corn ethanol and Brazilian sugarcane ethanol, we examine the energy, land, water and GHG performance of the two largest industrial fuel ethanol production systems in the world. Our comparisons include current and potential future systems with improved agronomic practices, crop yields, ethanol conversion processes, and utilization of agricultural residues. Our results suggest that the average water footprints of US corn ethanol and Brazilian sugarcane ethanol are fairly close (108 and 110 m3/GJ of ethanol, respectively) while the variations can range from 50 to 250 m3/GJ for sugarcane ethanol and 50 to380 m3/GJ for corn ethanol. Results emphasize the need to examine the water footprint within the context of local and regional climatic variability, water availability, competing uses (e.g. agricultural, industrial, and municipal water needs) and other ecosystem constraints. Research is under way (at the National Renewable Energy Laboratory and other institutions) to develop models to analyze water supply and demand at the watershed-scale for current and future biomass production, and to understand the tradeoffs among water supply, demand and quality due to more intensive agricultural practices and expansion of biofuels. Land use efficiency metrics, with regards to life cycle GHG emissions (without land use change) savings through gasoline displacement with ethanol, illustrate the progression of the biofuel industry and the importance of maximizing bioenergy production by utilizing both the crops and the residues.

    This report presents the Brazilian experience on the elaboration of a matrix of children's environmental health indicators to the Brazilian Health Surveillance System. This experience was part of a project with the financial support of the Ministry of Health of Brazil to develop appropriate indicators for identification, measuring, and monitoring of the environmental risk factors to the children's health. The methodology adopted for the development of the matrix of indicators of children's environmental health to Brazil comprised 3 steps. In the first step, the main causes of morbidity and mortality in the Brazilian population, aged 0-14 years, were identified, according to the data available from the Ministry of Health. The second step consisted of the identification of the Brazilian public-access information systems, with available official data regarding environmental, health, and socioeconomic conditions. In the third step, a preliminary matrix was elaborated. Correlation analyses were done to determine the indicators that would constitute the final matrix. The selected indicators allowed the identification and surveillance of cancer, injuries, adverse birth outcomes, diarrheic and respiratory diseases, associated with environmental risk factors, in the Brazilian child population. The existing Brazilian official information systems provided data with the necessary quality for the construction of children's environmental health indicators. Nevertheless, some official systems on health information presented limitations related to the data availability over the course of time and timeliness of data capture. Concerning the environmental information, the major limitation was accessibility. A matrix of indicators of children's environmental health to Brazil can come to contribute to the implementation of a surveillance system of children's exposure to environmental contaminants in Brazil.

    Full Text Available The infectious bronchitis virus (IBV was detected for the first time in Brazil by Hipólito in 1957 in chickens sold life in the municipal market of Belo Horizonte, MG, when commercial poultry production was just starting in that country. The Massachusetts (Mass serotype was identified. However, the clinical disease was only observed in 1975, when poultry production was intensely growing. The extensive outbreak produced the classical condition in layers and breeders, affecting egg production and quality, whereas broilers presented respiratory and "nephritis-nephrosis" signs. The disease rapidly spread to all poultry-producing regions in the country, and in 1979, both the imports and the manufacturing of live vaccines against IB strains Mass, H120 and H52, were licensed. In 1980, inactivated vaccines were introduced. Molecular techniques, particularly PCR, started to bed in the identification of IBV. A retrospective analysis showed that, up to 1989, the main IBV strain circulating in Brazil was Mass. However, other studies shows the presence of a wide diversity of IBV strains in Brazil since the first strains were isolated, even before vaccination was introduced. Most researchers agree that the incidence of IBV different from Mass has increased, including of exclusively Brazilian genotypes, different from those described in other countries. Indeed, during the last few years, the number of genotypical variants has been much higher than that of the classical Mass serotype. Clinically, in addition of the classic presentations, atypical forms such as testicular atrophy and stones in the epidydimis associated to low fertility have been described. Serological techniques started to be used in vaccination monitoring and as a diagnostic tool. Serological response standards were developed, and have shown to be very useful to determine the expected profile in vaccination programs and when clinical disease is suspected. However, the immuno-enzymatic test

    2009-05-01

    Full Text Available The article argues that theories of economic development are metaphors which have a strong mythical content, albeit unacknowledged by social scientists. The policies derived from such theories have two agendas: a “positive” agenda that states which problems should be tackled and how; and a “negative” agenda that contains issues and policies to be avoided. This approach is used to interpret the hegemonic view of development, as stated by the Washington Consensus, showing that such view contains all ingredients of a millenary myth – the crossing of the Desert towards a Promised Land. The two agendas of this view of development, which have ruled the Brazilian development strategy of the second half of the nineties, are then analyzed as applied to the Brazilian case. Finally, the article discusses alternative approaches to the present view of development, arguing for open-ended metaphors, as expressed by the Ulysses myth.

    2014-09-01

    Full Text Available This article aims to verify the factors associated with the development of human resource management (HRM competences in foreign subsidiaries of Brazilian multinationals. These competences are essential in that they allow foreign units to adopt HRM practices that are consistent with the countries or markets in which they operate. A multilevel research was conducted, involving headquarters and subsidiaries of major Brazilian companies; the empirical analysis employed hierarchical linear modelling. Despite the recurrent debate on global standardisation versus local adaptation, it was identified that the integration of international HRM policies (addressing simultaneously global guidelines and local response may stimulate competences development. In addition, interaction in external networks in the host country may enhance the development of HRM competences in the subsidiaries. However, specific cultural factors of the company may inhibit development activity in units abroad.

    2006-12-01

    Full Text Available This article presents some applications of airborne polarimetric and/or interferometric microwave data to improve the knowledge of forest structures. Three airborne SAR (Synthetic Aperture Radar experiments were done in the Amazon tropical forest: (a to study the spatial distribution of very large trees (VLTs in the primary forest using local maximum filtering and a series of Markov processes; (b to model the estimation of biomass variations in primary and secondary forests; (c to analyze the retrieval of timber volume over selective logging areas. Another experiment (d was to investigate the relation among SAR data and the volumetric configuration in stands of Eucalyptus sp. done by an airborne SAR imaging mission in SE-Brazil. To perform the objectives (b, (c and (d we carry out regression techniques, using variables got from multipolarimetric and/or interferometric SAR attributes and biophysical parameters from the forest cover. All data from the experiments were calibrated radiometrically to extract information during digital processing, besides an exhaustive field survey which was done simultaneously to SAR imaging, to know the physiognomy/structure of forest typology and to support the models produced for each case. The results of this series of experiments show advances at the techniques to treat SAR data, focusing on models of stand architecture and forest stock density. This will be helpful to increase the regional inventory and surveying procedures of forest conversion in the Brazilian territory in the near future.

    This research study aimed to evaluate the level of moral and ethical development of first-year students in a dental school. The students were presented with a dilemma that touched on personal and conflicting values. In responding to the questions posed, they had to present their criteria for judgments and norms that directly influence their behavior. Answers were then analyzed, leading to the categorization of interviewees into five stages of moral development according to Kohlberg's moral development system. The first, lowest stage in Kohlberg's system was reached by 11 percent of students. Most interviewees (47 percent) were in stage two, where individuals are conscious of their own conflicting interests, but an individualistic and instrumental set of morals tends to regulate those interests. Thirty percent of interviewees were identified with stage three, and 8.3 percent were found in stage four, whose main characteristic is the perception of self as a member of society, thus integrating interpersonal perspectives. Only one student reached stage five, in which the person recognizes universal rights and establishes a hierarchy of priorities. No individuals were found in stage six of moral development. The level of moral development found was low for students at this level, which may compromise the optimal moral development of the future dentist. The low level of moral development found may jeopardize the work of the future professionals, their treatment of patients, and society as a whole.

    Hydropower plants cause negative environmental impacts during the phases of construction and operation. On the other hand, there is a general assumption that these projects also induce local development of the affected places, since there is a great influx of social and financial capital brought locally, especially during the construction phase the relationship between hydropower plant implementation s and local development has been controversial in the Environmental Impact Assessment field, and there is no empirical evidence showing how hydroelectric dam construction affects local development. Considering municipal development as a kind of local development and operationalizing the concept of human development by adopting income, longevity and education dimensions defined by Amartya Sen, this study aimed to verify empirical evidences regarding the role of hydropower plants in human development of their flooded municipalities in Brazil. For this, we considered 134 hydroelectric plants and correspondent 641 flooded municipalities, for which 155 human development indicators were obtained for the period of 2000 to 2010. Results obtained from statistical correlation analysis and their assumption tests showed that increases in the municipal flooded area and increases in the period of flooding - to which a given municipality is submitted - were associated with lower performances of human development indicators. Specifically, increases in social inequality, poverty and lower performances of longevity and education were detected for the flooded municipalities. We also found that the financial compensation was associated with better performance of municipal income and lower performances of education and longevity. Finally, approaching the growth poles theory of François Perroux and the productive linkages theory of Albert Hirschman, we suggest that the size of the flooded areas, the flooding period and the financial compensation may lead to an enclave situation in

    2015-04-01

    Full Text Available This paper presents a review of the Brazilian scientific literature on the sense and meaning of work, in order to identify the researchers’ use of terminology and the branches of research on the subject. We examine a corpus of 70 papers electronically retrieved from databases for psychology and related fields through software-aided content analysis. The studies on the sense and meaning of work have primarily been developed since the year 2000, especially in the field of psychology. Most of these studies have a qualitative aspect and rely on a wide variety of distinct theoretical perspectives. These perspectives can be understood through four categories of terminological use: exclusive use of meaning of work; exclusive use of sense of work; use of both meaning and sense of work; and no identifiable or unique terminological preference.

    Full Text Available Schistosomiasis is a parasitic disease that, according to the World Health Organization, constitutes a major public health problem associated with severe morbidity, mostly children in preschool age. The administration of drugs in children always constitutes a difficult task, especially when formulations are not developed specifically for pediatric use, when high doses of drug are required and the drug has a bitter taste, as in the case of praziquantel. Polymer nanoparticles are promising systems for development of encapsulated drugs with low water solubility and bitter taste, due to the good physical and chemical stability, adequate biocompatibility and simple manufacturing processes. Moreover, they can enhance the bioavailabili-ty and reduce variability of treatment among patients. Poly (methyl methacrylate doped with praziquantel was produced through a miniemulsion polymerization pro-cess to compose a pediatric pharmaceutical suspension. Nanoparticles were cha-racterized in terms of physico-chemical properties, toxicological properties and biological activity in mice, being concluded that obtained results were satisfactory. The results were encapsulation rate around 90%, absence of chemical interaction drug - polymer and the presence of biological activity. A collaborative approach was used for this development, involving national partnerships and independent funding mechanisms, a powerful pathway for development of drugs for neglected diseases.

    It is well established that olfactory dysfunction has significant implications for safety, nutrition, and quality of life. The more reliable standardized tests of olfactory function, such as the University of Pennsylvania Smell Identification Test (UPSIT), assess odor identification ability. Unfortunately, cultural factors can influence such tests, as a number of odors are not universally recognized. In this study, a Portuguese language version of the UPSIT was administered to an age- and sex-stratified prospective sample of 1820 Brazilian subjects. Normative data were developed for a subset of 1578 subjects who reported having no difficulties smelling or tasting. Individuals with a history of head trauma or, in the case of those over the age of 64 years, Mini-Mental State Examination Scores <24, were excluded from analysis. As in other populations, the test scores were significantly influenced by age and sex. The median overall difference between the North American and Brazilian UPSIT scores was 2.2 points for men and 0.8 points for women, although subtle age-related differences were also apparent. This research represents that largest clinical study of olfaction ever performed in South America. Correction factors based upon age and sex are provided to allow for direct comparisons of Brazilian test scores to those based upon North American norms. © The Author 2014.

    2014-10-01

    Full Text Available OBJECTIVE: This study describes educational actions concerning organic foods conducted in Brazilian public schools and investigates how these actions are associated with the weekly workload and duration of employment of the dietician responsible for school meals. METHODS: In 2012 this cross-sectional, census-type study used an electronic questionnaire to collect data from dieticians or others responsible for school meals in all 5,565 Brazilian municipalities. The software Stata 11.0 was used for the statistical analyses. RESULTS: Although all Brazilian municipalities were contacted, 93.1% (n=5,184 replied. Of these, 94.2% had dieticians in charge of the school meals. Organic food-related educational actions were provided in the schools of 37.9% of the municipalities. The main actions were school gardening (67.1% and development of educational material (50.7%. Having a dietician responsible for school meals was not associated with the existence of educational actions at school (p=0.372. However, municipalities with dieticians in charge of school meals for at least twelve months were 22.0% and 20.0%, respectively, more likely to provide educational actions at school and include the subject 'organic foods' in the municipal school curriculum (p<0.05 for both. Dieticians' weekly work hours was directly related to the performance of school gardening-related activities (p=0.016. CONCLUSION: The percentage of Brazilian municipalities that provide organic food-related educational actions at school is low. Additionally, the availability of such actions relates to the dietician's duration of employment and weekly work hours.

    Miniature synaptic currents have long been known to represent random transmitter release under resting conditions, but much remains to be learned about their nature and function in central synapses. In this work, we describe a new class of miniature currents ("preminis") that arise by the autocrine activation of axonal receptors following random vesicular release. Preminis are prominent in gabaergic synapses made by cerebellar interneurons during the development of the molecular layer. Unlike ordinary miniature postsynaptic currents in the same cells, premini frequencies are strongly enhanced by subthreshold depolarization, suggesting that the membrane depolarization they produce belongs to a feedback loop regulating neurotransmitter release. Thus, preminis could guide the formation of the interneuron network by enhancing neurotransmitter release at recently formed synaptic contacts. Copyright 2010 Elsevier Inc. All rights reserved.

    Full Text Available It investigates the contradiction between paradigms of the current Process Civil Statute. On the one hand is the vertical effect of precedents, whose assumption is the identity between case for the replication of the decision and objective is legal certainty. On the other hand is the balancing, whose assumption is the uniqueness of the decision for the case and takes the contingency as an endless burden. To do so, it was based on the analysis of the legal-positive norm and the institutional history of previous procedures that resemble the investigated postulates to then enter into the recent doctrine on the themes. The mentioned contradiction was identified, as well as its near effects and close the initial possibilities of solutions. In addition to the literature review and leading cases, the critical method was used. It was found the divorce between the normative discourse, of which the foregoing are contained, and the act of judicial decision of the current dispute.

  10. A prospective analysis of Brazilian biofuel economy: Land use, infrastructure development and fuel pricing policies

    Nunez Amortegui, Hector Mauricio

    Being the two largest ethanol producers in the world, transportation fuel policies in Brazil and the U.S. affect not only their domestic markets but also the global food and biofuel economy. Hence, the complex biofuel policy climate in these countries leaves the public with unclear conclusions about the prospects for supply and trade of agricultural commodities and biofuels. In this dissertation I develop a price endogenous mathematical programming model to simulate and analyze the impacts of biofuel policies in Brazil and the U.S. on land use in these countries, agricultural commodity and transportation fuel markets, trade, and global environment. The model maximizes the social surplus represented by the sum of producers' and consumers' surpluses, including selected agricultural commodity markets and fuel markets in the U.S., Brazil, Argentina, China, and the Rest-of-the-World (ROW), subject to resource limitations, material balances, technical constraints, and policy restrictions. Consumers' surplus is derived from consumption of agricultural commodities and transportation fuels by vehicles that generate vehicle-kilometers-traveled (VKT). While in the other regional components aggregate supply and demand functions are assumed for the commodities included in the analysis, the agricultural supply component is regionally disaggregated for Brazil and the U.S., and the transportation fuel sector is regionally disaggregated for Brazil. The U.S. agricultural supply component includes production of fourteen major food/feed crops, including soybeans, corn and wheat, and cellulosic biofuel feedstocks. The Brazil component includes eight major annual crops, including soybeans, corn, wheat, and rice, and sugarcane as the energy crop. A particular emphasis is given to the beef-cattle production in Brazil and the potential for livestock semi-intensification in Brazilian pasture grazing systems as a prospective pathway for releasing new croplands. In the fuel sector of both

    Polyurethane foam (PUF) disk passive air samplers were deployed over summer (December-March) and winter (June-August) periods in 2007-2008 along altitudinal gradients in Brazilian southeastern and southern mountain regions. As part of the Global Atmospheric Passive Sampling (GAPS) Network, this work was initiated to address the lack of knowledge on the fate of legacy and current-use pesticides in South America, particularly in mountainous regions. Of the pesticides measured, concentrations in air were dominated by the current-use pesticides (CUPs) endosulfan (and its metabolite, endosulfan sulphate (EndoSO4)) and chlorpyrifos. Other pesticides that were regularly detected included α- and γ-hexachlorocyclohexanes (HCHs), dieldrin, heptachlor epoxide and p,p‧-DDE. Highest air concentrations were observed for total endosulfan (Endo I + Endo II + EndoSO4) (100s-1000s pg m-3), followed by chlorpyrifos, ΣDDT (mainly o,p‧-DDT + p,p‧-DDE), ΣHCH (α-HCH + γ-HCH), dieldrin and heptachlor epoxide. Seasonal variations did not show any clear trends for pesticides, except for endosulfan which reached concentration values one order of magnitude higher during summer at all sites compared to levels during winter. Along the altitudinal gradients, some pesticides showed higher atmospheric concentrations at sites above 1500 m which may indicate efficient high-altitude transport from regional sources. Northerly and southerly air back trajectories appeared to be the main continental influences at the two highest-altitude sites in both mountain regions. These trajectories travelled over extended crop areas from central Brazil to Argentina. A strong, positive correlation between air concentration and altitude was observed (Spearman's correlation, p < 0.05) for endosulfan, consistent with previous studies of endosulfan in mountainous regions in South America.

    Full Text Available Proficiency in management activities undertaken in product development processes is regarded as a key competitive advantage for companies, particularly for high-tech industrial firms, which benefit from the important competitiveness factor of launching products with a differentiated technological content. This paper’s objective was to identify, through case study, practices for integration between the roles of R & D with others involved in product development in a large Brazilian company of industrial automation. The results suggest some management practices to improve the integration in new products development, such as the use of employees from marketing with knowledge and experience previously gained from R & D activities and uses the heavyweight product manager to solve synchronization problems between product and technology development.

    Maya Reyes-Ricon

    2010-10-01

    Full Text Available The recent events in the global economy have revitalized the debate about the size and functions of the State. The neoliberal discourse was put in check, reopening the discussions concerning Market Liberty and the importance of the State. Since the proclamation of the Republic, the Brazilian government has undergone numerous reforms, sometimes assuming a liberal, external market dependent orientation, while at other times assuming an authoritarian, developmental state-driven orientation. The aim of this article is to develop insights into the evolution of the governmental organization and reflect on the assumptions that lie behind the various reforms that have taken place since the beginning of the Republic. The theoretical framework is divided into three parts: Development and Liberty based on the perspectives of Friedrich Hayek and Amartya Sen; the role of the State and its impact on the economy and; the formats assumed by the Brazilian State throughout the history of the Republic. The latter part of the work returns to the theoretical framework, summarizing all that has been discussed in order to fulfil the aims of the study.

    In this article, our aim is to analyze institutional practices guided to promote the development of moral values within the context of military education of Brazilian Army combatant commissioned officers. From a cultural psychological approach, we discuss how social guidance within military culture operates at different levels of the affective-semiotic regulation of individuals, structuring complex experiences that give rise to hypergeneralized meaning fields regarding morality and military values. For this goal, we first introduce some theoretical topics related to values development, emphasizing their affective roots and role in the emergence, maintenance, amplification and attenuation of all relations between the person and the environment. Following a brief discussion on how social institutions try to promote changes in personal values, we provide an overview of values present in the military culture and socialization. Finally, the text focuses on the education of Brazilian Army combatant commissioned officers, describing how practices related to different levels of affective-semiotic experience combine in order to promote the internalization and externalization of specific moral values. We conclude suggesting issues for future investigation.

    Current ANSTO scientific research on wasteform development for mainly high-level radioactive waste is directed towards practical applications. Titanate wasteform products we have developed or are developing are aimed at immobilization of: (a) tank wastes and sludges; (b) U-rich wastes from radioisotope production from reactor irradiation of UO2 targets; (c) Al-rich wastes arising from reprocessing of Al-clad fuels; (d) 99Tc; (e) high- Mo wastes arising from reprocessing of U-Mo fuels and (f) partitioned Cs-rich wastes. Other wasteforms include encapsulated zeolites or silica/alumina beads for immobilization of 129I. Wasteform production techniques cover hot isostatic and uniaxial pressing, sintering, and cold-crucible melting. In addition, building on previous work on speciation and leach resistance of Cs in cementitious products, we are studying geopolymers. Although we have a strong focus on candidate wasteforms for actual wastes, we have a considerable program directed at basic understanding of the wasteforms in regard to crystal chemistry, their dissolution behavior in aqueous media, radiation damage effects and processing techniques.

    Recognized as one of the world’s most vital natural and cultural resources, the Amazon faces a wide variety of threats from natural resource and infrastructure development. Within this context, rigorous scientific study of the region’s complex social-ecological system is critical to inform and direct decision-making toward more sustainable environmental and social outcomes. Given the Amazon’s tightly linked social and ecological components and the scope of potential development impacts, effective study of this system requires an easily accessible resource that provides a broad and reliable data baseline. This paper brings together multiple datasets from diverse disciplines (including human health, socio-economics, environment, hydrology, and energy) to provide investigators with a variety of baseline data to explore the multiple long-term effects of infrastructure development in the Brazilian Amazon.

    Full Text Available The aim of the present study is to identify the relationship between spending on research and development (R&D and the stock price of Brazilian companies listed for trading on the São Paulo Stock Exchange (Bovespa, following on the studies of Lopes (2001;2002 and Rezende (2005 about the value-relevance of accounting information in Brazil. This empirical-analytic study was based on the model of Collins et al. (1997, which is a proxy for the Residual Income Valuation (RIV model of Ohlson (1995, and on the classification of technological intensity in the study of Chan et al. (1990, carried out in the United States. The sample consisted of Brazilian firms with shares traded on the Bovespa between 1996 and 2006. By means of multiple regressions we identified that R&D spending is not statistically significant for the stock prices of the firms analyzed. These conclusions do not corroborate the findings of Chan et al. (1990, but do provide support for the studies of Ohlson (1995 and Lopes (2001; 2002 and complement the study by Rezende (2005, since our results indicate that earnings is statistically significant for stock price, with a positive relationship even after deducting R&D spending accounted for as expense. The situation is different for book value, which ceased being statistically significant and being related with stock price after deducting R&D spending accounted for as investment.

    Full Text Available Biofuel production has been greatly discussed in Brazil. In 2004, some debates lead the country to develop new policies and implement the National Biodiesel Use and Production Program (PNPB, with the intent to increase the share of renewable energy and foster sustainable regional development. In this context, the present study aims to assess the linkages between family farmer’s living standard and the adoption of oil seed activity in northern Brazil, in a region of transition between the Cerrado (Brazilian savanna and the Amazon rain forest. Ranges of socio-economic indicators were collected among smallholders who cultivate soybean. A fuzzy logic set theory based on living standard criteria and a non-linear probit model was applied to assess the inclusion of poor rural families in the biodiesel chain. Preliminary results point towards a negative relation between the family degree of deprivation and adoption of oil seed activity, for the soybean production.

    Full Text Available Premise of the study: Microsatellite markers were developed for Verbenoxylum reitzii (Verbenaceae, a tree endemic to the Brazilian Atlantic Forest, to investigate their usefulness in population genetic studies. The loci were tested for cross-amplification in the related genera Recordia and Duranta. Methods and Results: Eleven polymorphic microsatellite markers were isolated from an enriched library of V. reitzii and characterized. The primers were tested on 60 individuals from three populations of this species. The number of alleles per locus ranged from two to 11, and the observed and expected heterozygosities varied from 0.0 to 1.0 and from 0.088 to 0.758, respectively. Ten loci successfully amplified in R. boliviana and all failed in D. vestita. Conclusions: Our results suggest the usefulness of the microsatellite loci developed here to access genetic variability for phylogeographic and population genetic studies in V. reitzii, which are important for the conservation of this rare species.

    Full Text Available Population growth in the context of limited land resources makes the global scientific society research new ways to increase the agricultural yields. Over the past 20 years, biotechnology and GM crops have become widely spread and now are cultivated in 28 countries. The total area of crops has tripled, and it suggests the further vertical and horizontal integration in short term. In 2015, the US Department of Agriculture authorized the commercial use of GM farm animals. The development of agricultural biotechnology market is constrained by opponents of GM crops in more than 160 countries, which include Russia and the European Union, where the production of GM crops is banned due to economic, ethical, ideological and biological reasons. Currently, the EU is seeking to reduce the imports of GM crops and products; Russia's GM imports and exports are prohibited, and the deadline of designing a consolidated position on agricultural biotechnology has been moved to 2017. The author seeks to analyze the volume of production and international trade of agricultural products based on biotechnologies and to describe the main trends in the global market, which could be integrated into the food value chain in Russia. In the context of the worsening economic indicators, the article proposes the possibility of extending the use of GM crops in Russia non-food sector.

    Full Text Available In general, biological exposure limits are only used for the promotion and preservation of workers' health and are not applied for diagnostic purposes. However, the issue is controversial for certain types of occupational poisoning. This paper proposes the utilization of biological exposure limits currently applied to blood lead levels in Brazil as an important criterion for diagnosing occupational lead poisoning. The author argues that contrary to the traditional clinical criterion, one should deal with the diagnostic problem of lead poisoning from an epidemiological perspective, using the current Brazilian value for the biological exposure limit applied to blood lead level as an indicator of high relative risk.

    ECLAIRs, a 2-D coded-mask imaging camera on-board the Sino-French SVOM space mission, will detect and locate Gamma-ray bursts (GRBs) in near real time in the 4-150 keV energy band. The design of ECLAIRs has been mainly driven by the objective of achieving a low-energy threshold of 4 keV, unprecedented for this type of instrument. The detection plane is an assembly of 6400 Schottky CdTe semiconductor detectors of size 4x4x1 mm3 organized on elementary hybrid matrices of 4x8 detectors. The detectors will be polarized from -300V to -500V and operated at -20°C to reduce both the leakage current and the polarization effect induced by the Schottky contact. The remarkable low-energy threshold homogeneity required for the detection plane has been achieved thanks to: i) an extensive characterization and selection of the detectors, ii) the development of a specific low-noise 32-channel ASIC, iii) the realization of an innovative hybrid module composed of a thick film ceramic (holding 32 CdTe detectors with their high voltage grid), associated to an HTCC ceramic (housing the ASIC chip within an hermetic enclosure). In this paper, we start describing a complete hybrid matrix, and then the manufacturing of a first set of 50 matrices (representing 1600 detectors, i.e. a quarter of ECLAIRs detector's array). We show how this manufacturing allowed to validate the different technologies used for this hybridization, as well as the industrialization processes. During this phase, we systematically measured the leakage current on Detector Ceramics after an outgassing, and the Equivalent Noise Charge (ENC) for each of the 32 channels on ASIC Ceramics, in order to optimize the coupling of the two ceramics. Finally, we performed on each hybrid module, spectral measurements at -20°C in our vacuum chamber, using several calibrated radioactive sources (241Am and 55Fe), to check the performance homogeneity of the 50 modules. The results demonstrated that the 32-detector hybrid matrices

    Brazilian jiu-jitsu is characterized by musculoskeletal disorders and high occurrence of sports injuries. The present study was aimed to analyze some internal factors, as well as to describe occurrence and characteristics of retrospective musculoskeletal injuries in different age groups of Brazilian jiu-jitsu practitioners. One hundred ninety-three Brazilian jiu-jitsu practitioners, which were divided into three age groups: Adolescent, Adult, and Master. Besides anthropometric characterization, standard clinical tests were conducted to analyze the global and segmental joint flexibility, lumbar spine range of motion, and handgrip strength. Sports injury occurrence and total physical activity were obtained from an adapted morbidity survey and International Physical Activity Questionnaire - Short Form (IPAQ-SF), respectively. A total of 247 cases of retrospective injuries was registered (1.27 injury/ participant). Occurrence of rectus femoral muscle retraction in the right leg was increased within Master. Adult and Master have exhibited higher occurrence of sports injuries than Adolescent group (p Brazilian jiu-jitsu practitioners. While female gender and exposure time constituted the most predictive variables for sports injury occurrence in Adolescent, graduation level was more associated with sports injuries occurrence in Adult. Joint injuries derived from combat demands were the main sports injury in all age categories of Brazilian jiu-jitsu. Master subjects presented a higher occurrence of clinical changes and retrospective musculoskeletal injuries in relation to other age groups. Female gender and exposure time constituted the main predictive factors in adolescent subjects, while graduation category was more directly associated with retrospective injury onset in the Adult group.

    The preparation of enantiomerically pure or enriched substances is of fundamental importance to pharmaceutical, food, agrochemical, and cosmetics industries and involves a growing market of hundreds of billions of dollars. However, most chemical processes used for their production are not environmentally friendly because in most cases, stoichiometric amounts of chiral inductors are used and substantial waste is produced. In this context, asymmetric catalysis has emerged as an efficient tool for the synthesis of enantiomerically enriched compounds using chiral catalysts. More specifically, considering the current scenario in the Brazilian chemical industry, especially that of pharmaceuticals, the immediate prospect for the use of synthetic routes developed in Brazil in an enantioselective fashion or even the discovery of new drugs is practically null. Currently, the industrial production of drugs in Brazil is primarily focused on the production of generic drugs and is basically supported by imports of intermediates from China and India. In order to change this panorama and move forward toward the gradual incorporation of genuinely Brazilian synthetic routes, strong incentive policies, especially those related to continuous funding, will be needed. These incentives could be a breakthrough once we establish several research groups working in the area of organic synthesis and on the development and application of chiral organocatalysts and ligands in asymmetric catalysis, thus contributing to boost the development of the Brazilian chemical industry. Considering these circumstances, Brazil can benefit from this opportunity because we have a wide biodiversity and a large pool of natural resources that can be used as starting materials for the production of new chiral catalysts and are creating competence in asymmetric catalysis and related areas. This may decisively contribute to the growth of chemistry in our country. (author)

    2017-10-01

    Full Text Available One of the most important demands imposed by the consumer market on the Brazilian Productive Chain of Flowers and Ornamental Plants is the constant launching of innovations in cultivated species and varieties. Such innovations include the constant introduction of flowers and plants not yet grown and commercialized, both native and adapted exotic species, as well as transformations and changes in size, shape, coloring and conduction patterns and presentation of these goods to the market. Brazil does not have a relevant breeding and cultivation industry. In this sense, it is highly dependent on imports of genetic material developed by countries such as the Netherlands, Germany, Japan, the United States of America, Thailand, among others. Recent developments in the sectoral policy to protect the rights of genetic developers, in the development of internationally adequate legislation and in the control of the use and trade of cultivars, has allowed Brazil greater access to new genetic materials of high quality and in line with contemporary international trends in the consumption. This article aims to discuss the state of the art of protection of cultivars in Brazil, pointing to the advances that the legislation and the inspection have allowed in relation to the introduction of genetic innovations, evaluating the impact of these measures on the growth and development of the market of consumption of flowers and ornamental plants in the country.

    Lutjanid species exhibit multiple spawning behaviour during an extended spawning season in warm months, asynchronous oocyte development and indeterminate fecundity. Although early studies have contributed to knowledge of the reproductive cycle of many species within the group, they have not considered aspects about the number of cortical alveoli oocyte stage throughout maturity phases along spawning season. The latter aspect is also considered very important to confirm indeterminate fecundity hypothesis. In the present study, were analyzed 154 Brazilian snapper Lutjanus alexandrei female gonads obtained from artisanal fisheries in Pernambuco State (Brazil) between October 2010 and March 2011. Were measured oocyte size frequency distribution for maturity phases (developing, spawning capable and actively spawning), and oocyte development stage (unyolked oocytes, cortical alveoli, primary, secondary and tertiary vitellogenic oocytes and hydrated oocytes), and also the oocyte stage frequency during spawning season. The frequency of cortical alveoli oocyte stage was constantly found in the spawning period (>37%), showing slight variation throughout maturity phases. The absence of gap in the oocyte size frequency distribution between primary and secondary oocyte growth stages during spawning season is a strong indicator of continuous oocyte recruitment from reserve stocks. In addition, co-occurrence of tertiary vitellogenic oocytes, hydrated oocytes, post-ovulatory follicles and yellow-brown bodies in the histological sections of ovaries reinforce indeterminate fecundity hypothesis.

    2008-04-01

    Beamed energy propulsion and beamed energy vehicle performance control concepts are equally promising and challenging. In Brazil, the two concepts are being currently investigated at the Prof Henry T Nagamatsu Laboratory of Aerothermodynamics and Hypersonics, of the Institute for Advanced Studies—IEAv, in collaboration with the Rensselaer Polytechnic Institute—RPI, Troy, NY, and the United States Air force Research Laboratory-AFRL. Until recently, only laser energy addition for hypersonic flow control was being investigated at the Laboratory using a 0.3 m nozzle exit diameter hypersonic shock tunnel, T2, and two 7 joule CO2 TEA lasers. Flow visualization, model pressure and heat flux measurements of the laser energy addition perturbed flow around a model were produced as a result of this joint IEAv-RPI investigation. Presently, with the participation of AFRL and the newly commissioned 0.6 m. nozzle exit diameter hypersonic shock tunnel, T3, a more ambitious project is underway. Two 400 Joule Lumonics 620 CO2 TEA lasers will deliver a 20 cm X 25 cm propulsive laser beam to a complete laser propelled air breather/rocket hypersonic engine, located inside T3 test section. Schlieren photographs of the flow inside de engine as well as surface and heat flux measurements will be performed for free stream Mach numbers ranging from 6 to 25. The present paper discusses past, present and future Brazilian activities on beamed energy propulsion and related technologies.

    This paper looks at the greenhouse gas (GHG) emissions trading schemes and examines the prospects of carbon trading. The first part of the paper gives an overview of several mandatory GHG trading schemes around the world. The second part focuses on the future trends in carbon trading. It argues that the emergence of new schemes, a gradual enlargement of the current ones, and willingness to link existing and planned schemes seem to point towards geographical, temporal and sectoral expansion of emissions trading. However, such expansion would need to overcome some considerable technical and non-technical obstacles. Linking of the current and emerging trading schemes requires not only considerable technical fixes and harmonisation of different trading systems, but also necessitates clear regulatory and policy signals, continuing political support and a more stable economic environment. Currently, the latter factors are missing. The global economic turmoil and its repercussions for the carbon market, a lack of the international deal on climate change defining the Post-Kyoto commitments, and unfavourable policy shifts in some countries, cast serious doubts on the expansion of emissions trading and indicate that carbon trading enters an uncertain period. - Highlights: > The paper provides an extensive overview of mandatory emissions trading schemes around the world. > Geographical, temporal and sectoral expansion of emissions trading are identified as future trends. > The expansion requires considerable technical fixes and harmonisation of different trading systems. > Clear policy signals, political support and a stable economic environment are needed for the expansion. > A lack of the post-Kyoto commitments and unfavourable policy shifts indicate an uncertain future for carbon trading.

  19. Current developments concerning medial tibial stress syndrome.

    Science.gov (United States)

    Craig, Debbie I

    2009-12-01

    Medial tibial stress syndrome (MTSS) is one of the most common lower leg injuries in athletes who run. Studies have reported MTSS to occur in 4% to 20% of this population. It can be defined as an overuse injury that creates pain over an area covering the distal to middle third of the posteriomedial tibial border, which occurs during exercise and creates cyclic loading. Differential diagnosis includes ischemic disorders and stress fractures. Although the pathology of this injury is understood, the etiology is less agreed upon. This makes it difficult for clinicians to diagnose and treat this common injury. The purpose of this article is to present health care practitioners with the most current information regarding MTSS so they can better diagnose and treat this common injury. To this end, a literature review was conducted, with the most current results presented. The areas of etiological theories, imaging techniques, and treatment options for MTSS were searched. Five of the most prevalent etiological theories are presented with supporting evidence. Of the imaging tools available to the clinician, magnetic resonance imaging (MRI) and bone scintigraphy have comparable specificity and sensitivity. Clinicians should first make the clinical diagnosis of MTSS, however, because of high percentages of positive MRI scans in asymptomatic patients. There have been few randomized controlled trials investigating treatment options for athletes with MTSS. Those that have been performed rendered no significant findings, leading researchers to conclude that rest is equal to or better than other treatment options. Given the evidence, treatment suggestions for practitioners caring for athletes with MTSS are provided.

    Stingless bees are an important asset to assure plant biodiversity in many natural ecosystems, and fulfill the growing agricultural demand for pollination. However, across developing countries stingless beekeeping remains an essentially informal activity, technical knowledge is scarce, and management practices lack standardization. Here we profited from the large diversity of stingless beekeepers found in Brazil to assess the impact of particular management practices on productivity and economic revenues from the commercialization of stingless bee products. Our study represents the first large-scale effort aiming at optimizing stingless beekeeping for honey/colony production based on quantitative data. Survey data from 251 beekeepers scattered across 20 Brazilian States revealed the influence of specific management practices and other confounding factors over productivity and income indicators. Specifically, our results highlight the importance of teaching beekeepers how to inspect and feed their colonies, how to multiply them and keep track of genetic lineages, how to harvest and preserve the honey, how to use vinegar traps to control infestation by parasitic flies, and how to add value by labeling honey containers. Furthermore, beekeeping experience and the network of known beekeepers were found to be key factors influencing productivity and income. Our work provides clear guidelines to optimize stingless beekeeping and help transform the activity into a powerful tool for sustainable development.

    One of the most strategical factor in the field of the generation of electric energy, especially for power levels of 500 kW or higher, is the domain of the gas turbine technology and, in this aspect, few countries in the world withhold it. The objectives of the present work are: to project, to calculate, and to construct a gas turbine, based in the use of the natural gas as combustible. To accomplish these objectives the project was planned to be developed in two phases; in the first one, we envisage the set up of a concept test unit, for evidencing the capability of the involved team and of the national suppliers for manufacturing and providing the gas turbine parts. The second stage was planned to project and to construct a prototype unit for certification of the Brazilian gas turbine, aiming finally at the industrial production and commercialization, to attend the marked demand for gas turbines of power levels within the range of 500 kW to 2000 kW, using natural gas as fuel. In this work we show that the results obtained up to now - when we are in the final of the first phase - prove the existence of national technological strength for producing and supplying key parts of gas turbines, as well as qualified human resources to develop and dominate the complete gas turbine technology, in a sufficiently short period.

    Full Text Available Context: Oils and butter of seed from Brazilian biodiversity are extending the range of innovative products for cosmetics development. They have a fat potential similar to skin composition, leading to the improved performance of these product. Aims: Improve the emulsions spreadability through prior screening of grease composition and studying the viscosity, and the emulsions accelerated stability. Methods: Emulsions were formulated using oils from semiarid plants from Bahia: Syagrus coronate, Pachira retusa, and Pachira aquatica, so as to compare them with oils already standard in the production of cosmetics. Spreadability and stability tests were made comparing the results. The same criteria were used with Amazon seed butter: Virola surinamensis, Butyrospermum parkii, Astrocaryum murumuru, Theobroma cacao and Theobroma grandiflorum. For the emulsions screening and performance, a system was developed for oil/ butter, following tests of accelerated stability, viscosity, and spreadability. Results: The combined system of spreadability was optimized using screening. Emollients containing oleic and palmitic acids, and light chain fatty acids obtained good spreadability. The oil emulsion containing Pachira retusa and Virola surinamensis butter had a higher viscosity. Conclusions: With high content of fatty acids such as oleic, palmitic or the light chain fatty acids obtain an appropriated appearance, texture, and spreadability for cosmetic use. Thus, oils with a low fatty acid content may be combined with butter that have a high fatty acid content and vice-versa. Analyzing and strategically combining grease composition, one can optimize the performance of cosmetic formulations.

    Full Text Available Stingless bees are an important asset to assure plant biodiversity in many natural ecosystems, and fulfill the growing agricultural demand for pollination. However, across developing countries stingless beekeeping remains an essentially informal activity, technical knowledge is scarce, and management practices lack standardization. Here we profited from the large diversity of stingless beekeepers found in Brazil to assess the impact of particular management practices on productivity and economic revenues from the commercialization of stingless bee products. Our study represents the first large-scale effort aiming at optimizing stingless beekeeping for honey/colony production based on quantitative data. Survey data from 251 beekeepers scattered across 20 Brazilian States revealed the influence of specific management practices and other confounding factors over productivity and income indicators.

  5. Energy-conserving development regulations: current practice

    Energy Technology Data Exchange (ETDEWEB)

    1980-05-01

    Almost every aspect of land development has an effect on energy use, from minute architectural details to broad considerations of urban density. Energy-efficiency depends in part on how development is planned and carried out. Conventional development regulations, such as zoning ordinances and subdivision regulations, can be adapted in many ways to promote energy conservation at the community level. This report is about energy-efficient site and neighborhood design. It examines recent experiences of local governments that have adopted new development regulations or amended existing ones to promote energy conservation, more efficient generation and distribution, or a switch to alternative, renewable sources. Although much has been written in recent years about saving energy through community design, actual experience in applying these new ideas is still limited. To date, most communities have focused their efforts on studying the problem, documenting consumption patterns, and writing reports and plans. Only a handful have amended their land-use controls for the express purpose of saving energy. This study identifies 13 of these pioneering communities, after undertaking a survey of over 1400 local, regional, and state planning agencies. It takes a look at their experiences, to learn what has been done, how well it has worked, and what problems have been encountered.

    General reduction of dental caries and patient interest in dental aesthetics have resulted in the development of new restorative materials and techniques. Composite materials and adhesive techniques have become the foundation of modern restorative dentistry. Mechanical performance, wear resistance, and aesthetic potential of composite resins have been significantly improved, and the material is now used in cases ranging from the restoration of initial decays and cosmetic corrections to the veneering in extended prosthetic rehabilitation. Polymerization shrinkage of the resin matrix remains a challenge and still imposes limitations in the application of direct techniques. The learning objective of this article is to review the most significant advances of composite materials and the importance of utilizing the available treatment options with discretion, selecting those which preserve the tooth structure and require the least maintenance.

    Full Text Available This article presents a systematization and quantitative evaluation of the economic literature regarding the Brazilian Development Bank – BNDES – produced since its foundation, in 1952, until 2013. We identified, catalogued, read and analyzed approximately 1000 studies, in order to understand what were the major themes and questions raised in this literature, what types of methodologies were employed and how these changed over time, as well as indicators of authorship, collaboration and institutional affiliation. Using this database, a quantitative analysis was carried out using the following indicators: (i production, which evaluates both the quantity and characteristics of these publications, (ii impact, which measures the repercussion of this production and (iii relational, which evaluates citation, co-citation and co-authorship networks. The results showed a growing trend in the number of publications, especially in the last two decades. Additionally, this analysis revealed that the distribution of these publications was significantly concentrated in terms of the most cited documents, the most prolific authors and the institutions which sponsored these publications. Furthermore, a network analysis showed a reduced density in the citation and co-authorship networks, as well as isolated debates on certain themes.

    This study investigated the possible correlation between the mineralization of the second molars and the chronological age of a sample population of the state of Paraiba, Brazil. One thousand eight hundred fifty-four digitized panoramic images using a scanner of a private dental radiology service were obtained in six months. Of these, 457 were selected from patients aged 4.6 to 16 years who met certain criteria. The images were assessed twice by a radiologist with 5 years experience. A minimum interval of 30 days between the evaluations of the same patient was established. To analyze the relationship between chronological age, calcification level proposed by Demirjian et al in 1973, gender, and tooth, a multiple linear regression model was adjusted, taking age as the response variable (p<0.05). The gender and calcification level were significantly correlated with the age of the patients (p<0.05). There was a significant difference between the average age of the patients' upper teeth compared to the lower ones in both genders (p<0.05). The dental development occurred earlier in female individuals than in male ones, and there was no significant difference between the right and left second permanent molars. It was observed that ethnic variables are related to certain parameters of age and sex identification in the Brazilian population, providing important information for forensic evaluations.

    To compare the occurrence of sleep complaints among senior citizens resident in the local communities of two municipalities with differing Human Development Indices (HDIs): Campinas, State of São Paulo (IDH = 0.852) and Parnaíba, State of Piauí (IDH = 0.674). Descriptive study as part of the multicentric project going by the name of Frailty among Brazilian Senior Citizens (Fragilidade em Idosos Brasileiros--FIBRA). A total of 988 senior citizens were analysed, making use of a social and demographic questionnaire about sleep problems (Nottingham Health Profile); questions about naps (Minnesota Leisure Activity Questionnaire). The Chi-Square and Mann-Whitney tests were used in the analysis of the data, at a significance level of 5% (p<0.05). The chronologically advantaged individuals in Parnaíba showed a higher incidence of sleep complaints when compared to the senior citizens of Campinas. There was a significant association between municipality and the following variables: number of sleep complaints, non-restoring sleep, precocious awakening, difficulty in falling and staying asleep. The nursing staff must intervene in favour of the promotion of health with actions that either reduce or prevent these sleep-related problems.

    To assess the use of a health monitoring tool in Brazilian children, with emphasis on the variables related to growth and development, which are crucial aspects of child health care. A systematic review of the literature was carried out in studies performed in Brazil, using the Cochrane Brazil, Lilacs, SciELO and Medline databases. The descriptors and keywords used were "growth and development", "child development", "child health record", "child health handbook", "health record and child" and "child handbook", as well as the equivalent terms in Portuguese. Studies were screened by title and summary and those considered eligible were read in full. Sixty-eight articles were identified and eight articles were included in the review, as they carried out a quantitative analysis of the filling out of information. Five studies assessed the completion of the Child's Health Record and three of the Child's Health Handbook. All articles concluded that the information was not properly recorded. Growth monitoring charts were rarely filled out, reaching 96.3% in the case of weight for age. The use of the BMI chart was not reported, despite the growing rates of childhood obesity. Only two studies reported the completion of development milestones and, in these, the milestones were recorded in approximately 20% of the verified tools. The results of the assessed articles disclosed underutilization of the tool and reflect low awareness by health professionals regarding the recording of information in the child's health monitoring document.

    Phloem, as a major tissue mediating long-distance communication, has been an object of extensive research ever since its structure was first reported in 1837. Functional phloem consists of sieve elements (SEs) and companion cells (CCs). While SEs are enucleated conducting cells in the phloem, CCs are cells with intact cellular components and are known to support the functioning of SEs. CCs are closely linked to SEs by symplastic connections mediated by plasmodesmata (PD). Sieve elements are notoriously sensitive to manipulation, which has hampered efforts to investigate their structure using microscopy or histology; phloem thus remains a mysterious tissue almost 200 yr after its discovery. Nevertheless, consistent efforts have overcome many of the technical barriers and generated considerable amounts of data about the structure and function of phloem. Advances in the 1950s and 1960s significantly improved our understanding of phloem anatomy and function. A major function of the phloem is to establish symplastic connections throughout the plant body, delivering nutrients and various signaling molecules, which play pivotal roles in growth and development. Despite the importance of phloem, details about the molecular mechanisms responsible for the establishment and maintenance of phloem continuity remain elusive. © 2014 Botanical Society of America, Inc.

    Air quality is a public health issue and this article includes a reminder of the related causes and issues and a description of the monitoring of ambient air quality in France. It also provides a review of major developments in recent years of the pollutants measured. Emissions of major air pollutants have declined significantly since the 1970s, and this is reflected in an overall improvement in the quality of ambient air. Nevertheless, various forms of air pollution remain a concern (in the case of photochemical pollution) and health data show that air pollution is still a cause of morbidity and mortality. The fight against air pollution must remain a priority and requires multi-pollutant and multi-effect approaches. The National Health and Environment Program adopted during the Grenelle environment stakeholder consultation processes includes targets for reducing human exposure to air pollution, especially particulate matter, as well as measures to improve indoor air quality. In a context dominated by the struggle against the emission of greenhouse gases, problems of air quality should not be underestimated and policies relating to climate protection must be taken into account.

    The goal of this study was to translate, adapt and validate the items of the Gap-Kalamazoo Communication Skills Assessment Form for use in the Brazilian cultural setting. The Gap-Kalamazoo Communication Skills Assessment Form was translated into Portuguese by two independent bilingual Brazilian translators and was reconciled by a third bilingual healthcare professional. The translated text was then assessed for content using a modified Delphi technique and adjusted as needed to assure content validity. A total of nine phrases in the completed tool were adjusted. The final tool was then used to assess videotaped simulations as a means of validation.  Response process was assessed using exploratory factor analysis and internal structure was assessed via Cronbach's Alpha (internal consistency) and Intraclass Correlation (test-retest reliability and inter-rater reliability). One hundred and four (104) videotaped communication skills simulations were assessed by 38 subjects (6 staff physicians, 4 faculty physicians, 8 resident physicians, 4 professional actors with experience in simulation, and 16 other allied healthcare professionals). Measures of Internal consistency (Cronbach's alpha = 0.818) and test-retest reliability (intra-class correlation coefficient = 0.942) were high.  Exploratory factor analysis confirmed the uni-dimensionality of the instrument. Our results support the validity and reliability of the Brazilian Gap-Kalamazoo Communication Skills Assessment Form when used among Brazilian medical residents.  The Brazilian version of Gap-Kalamazoo Communication Skills Assessment Form was found to be adequate both in the linguistic and technical aspects.  The use of this instrument in Brazilian medical education can enhance the assessment of physician-patient-team relationships on an ongoing basis.

    2010-01-01

    Background Economic development is often evoked as a driving force that has the capacity to improve the social and health conditions of remote areas. However, development projects produce uneven impacts on local communities, according to their different positions within society. This study examines the spatial distribution of three major health threats in the Brazilian Amazon region that may undergo changes through highway construction. Homicide mortality, AIDS incidence and malaria prevalence rates were calculated for 70 municipalities located within the areas of influence of the Cuiabá-Santarém highway (BR-163), i.e. in the western part of the state of Pará state and the northern part of Mato Grosso. Results The municipalities were characterized using social and economic indicators such as gross domestic product (GDP), urban and indigenous populations, and recent migration. The municipalities' connections to the region's main transportation routes (BR-163 and Trans-Amazonian highways, along with the Amazon and Tapajós rivers) were identified by tagging the municipalities that have boundaries crossing these routes, using GIS overlay operations. Multiple regression was used to identify the major driving forces and constraints relating to the distribution of health threats. The main explanatory variables for higher malaria prevalence were: proximity to the Trans-Amazonian highway, high proportion of indigenous population and low proportion of migrants. High homicide rates were associated with high proportions of migrants, while connection to the Amazon River played a protective role. AIDS incidence was higher in municipalities with recent increases in GDP and high proportions of urban population. Conclusions Highways induce social and environmental changes and play different roles in spreading and maintaining diseases and health threats. The most remote areas are still protected against violence but are vulnerable to malaria. Rapid economic and demographic

    Full Text Available The aim of this paper is to investigate whether Brazilian manufacturing firms are credit constrained. We exploit a rich database that contains more than three thousand firms with characteristics that may affect their degree of credit constraint: size, being listed in the Brazilian stock market and level of exports-sales ratio. Our results show that all dimensions considered here may affect the sensitiveness of investment to cash flow. Large firms, stock market listed firms as well as firms with better export capacity are associated with inexistence or less credit restriction. Specifically, considering firms’ size, our results corroborate the economic theory prediction and empirical international literature. Furthermore, the influence of being listed in the stock market and export capacity is beyond any possible correlation with size. Even small and middle firms are not credit constrained when listed in the stock market or when the exports-sales ratio is higher.

    Brazil is a country of continental dimensions with a large heterogeneity of climates and massive mixing of the population. Almost the entire national territory is located between the Equator and the Tropic of Capricorn, and the Earth axial tilt to the south certainly makes Brazil one of the countries of the world with greater extent of land in proximity to the sun. The Brazilian coastline, where most of its population lives, is more than 8,500 km long. Due to geographic characteristics and cultural trends, Brazilians are among the peoples with the highest annual exposure to the sun. Epidemiological data show a continuing increase in the incidence of non-melanoma and melanoma skin cancers. Photoprotection can be understood as a set of measures aimed at reducing sun exposure and at preventing the development of acute and chronic actinic damage. Due to the peculiarities of Brazilian territory and culture, it would not be advisable to replicate the concepts of photoprotection from other developed countries, places with completely different climates and populations. Thus the Brazilian Society of Dermatology has developed the Brazilian Consensus on Photoprotection, the first official document on photoprotection developed in Brazil for Brazilians, with recommendations on matters involving photoprotection.

To do this, first, we examine the basis of postcolonial theory, especially the general context where it emerged. Then, we examine the historical context of Brazil in the 1950s and 1960s, by discussing works by the author that portrayed the transformations in the country within this period. We devote special attention to his sociological reduction theory, as it shows his concern to discuss both epistemic colonialism and his idea of development. Finally, we compare how the postcolonial approach and Guerreiro Ramos' ideas relate to one of the most widespread theories having the precept of development as its main source of legitimacy: the International Business and Management Studies (IBMS. This analysis demonstrates that epistemic colonialism was among the key issues of Guerreiro Ramos' thought. However, we conclude that, despite the author's merits in having raised an earlier discussion that is congruent with postcolonial concerns, his thought was deeply rooted in a mystified idea of international development, similar to that of IBMS, very criticized by postcolonialism. This article seeks to contribute to the Brazilian critical organization studies, by showing the potential of postcolonial thought to challenge and defamiliarize ethnocentric and universalistic assumptions that have grounded theories and decision making processes in most of the world's societies since World War II.

    A space weather program is being initiated at the Brazilian National Institute for Space Research (INPE) to study events from their initiation on the sun to their impacts on the earth, including their effects on space-based and ground-based technological systems. The program is built on existing capabilities at INPE, which include scientists with a long tradition and excellence in the observation, analysis and modeling of solar and solar-terrestrial phenomena and an array of geophysical instruments that spans all over the Brazilian territory from the north to south of the magnetic dip equator. Available sensors include solar radio frequency receivers and telescopes, optical instruments and solar imagers, GNSS receivers, ionosondes, radars, allsky imagers, magnetometers and cosmic ray detectors. In the equatorial region, ionosphere and thermosphere constitute a coupled system with electrodynamical and plasma physical processes being responsible for a variety of peculiar phenomena. The most important of them are the equatorial electrojet current system and its instabilities, the equatorial ionization anomaly, and the plasma instabilities/irregularities of the night-time ionosphere (associated with the plasma bubble events). In addition, space weather events modify the equatorial ionosphere in a complex and up to now unpredictable manner. Consequently, a main focus of the program will be on monitoring the low, middle and upper atmosphere phenomena and developing a predictive model of the equatorial ionosphere through data assimilation, that could help to mitigate against the deleterious effects on radio communications and navigation systems. The technological, economic and social importance of such activities was recognized by the Brazilian government and a proposal for funding was approved for the period 2008-2011. New ground instruments will be installed during this period allowing us to extend our current capability to provide space weather observations, accurate

    Full Text Available This study aims to offer a model to apply the VMI to manage purchasing and inventory in the Brazilian footwear industry as this industry’s is inserted in a rising product diversity environment, with shorter product lifecycle while facing heavy, international competitive pressures. The model that is being proposed is also related to establishing minimum inventory levels and the ideal inventory replenishment cycle for industrial operations, and it also classifies materials according to their financial impact and to how critical their provision is. This research, which is defined as an exploratory and qualitative one, addresses a case study of a Brazilian footwear company to gather fundamental information associated with operations history, strategic operational characteristics in the purchasing area, and purchasing management systems, all performed by means of an in-depth interview. When data was analyzed, it showed that among the various materials used by a footwear company, the use of VMI would be needed for materials that were classified as being non-critical components and competitive components, that is, those with a low degree of uncertainty regarding to offer and both high and low financial impact, respectively.

    Full Text Available Two different approaches, referred to as Bu and Ej, can be used to examine the time development of electric fields and currents in space plasmas based on the fundamental laws of physics. From the Bu approach, the required equation involves the generalized Ohm's law with some simplifying assumptions. From the Ej approach, the required equation can be derived from the equation of particle motion, coupled self-consistently with Maxwell's equation, and the definition of electric current density. Recently, some strong statements against the Ej approach have been made. In this paper, we evaluate these statements by discussing (1 some limitations of the Bu approach in solving the time development of electric fields and currents, (2 the procedure in calculating self-consistently the time development of the electric current in space plasmas without taking the curl of the magnetic field in some cases, and (3 the dependency of the time development of magnetic field on electric current. It is concluded that the Ej approach can be useful to understand some magnetospheric problems. In particular, statements about the change of electric current are valid theoretical explanations of change in magnetic field during substorms.

    This paper describes the comparison results of sizing performance for two systems. The KHNP developed a new eddy current testing system for the inspection of steam generator tubing in domestic nuclear power plants. The equivalency assessment of the newly developed system with the EPRI-qualified system was already carried out. In this paper, the comparisons of depth-sizing performance for the artificial flaws between two systems were performed. The results show that the newly developed system is in good agreement with the qualified system. Therefore, it is expected that the newly developed eddy current system can be used for the inspection of steam generator tubing in nuclear power plants. There are some non-destructive examination (NDE) methods for the inspection of components in nuclear power plants, such as ultrasonic, radiographic, eddy current testing, etc. The eddy current testing is widely used for the inspection of steam generator (SG) tubing because it offers a relatively low cost approach for high speed, large scale testing of metallic materials in high pressure and temperature engineering systems. The Korea Hydro and Nuclear Power Co., Ltd. (KHNP) developed an eddy current testing system for the inspection of steam generator tubing in nuclear power plants. This system includes not only hardware but software such as the frequency generator and data acquisition-analysis program. The foreign eddy current system developed by ZETEC is currently used for the inspection of steam generator tubing in domestic nuclear power plants. The equivalency assessment between two systems was already carried out in accordance with the EPRI steam generator examination guidelines.

    2014-06-01

    Full Text Available The growth of industries and the strong economic base in Brazil require improvements and adaptations in business processes. Cross-functional teams (CFT may help to companies achieve these improvements. This research looks at characterizing CFT according to application processes, structures, objectives and impacts, considering the context of demand planning and related processes. In-depth interviews with 22 managers were performed in three Brazilian manufacturing companies. A framework to characterize CFT and respective impacts is proposed, including elements such as: procedures, context and goals, power distribution, impacts on cross-functional integration, impacts on teams' performance and on organization's performance. One significant managerial finding is that effective and efficient CFTs need balanced distribution of power among members by effectively establishing and structuring the team. By doing this, managers may observe positive impacts on inter-functional integration and in firm's results. Moreover, teams should permanently perform joint planning to predict unfavorable situations, improve communication and mutual understanding.

    Full Text Available This experimental study focuses on the relationship between language development and the reasoning of first-order false belief (FB standard tasks by children acquiring Brazilian Portuguese. We investigate to what extent mastering specific language structures, such as complementing syntax, affects the performance of this kind of reasoning by 3-4 year olds, as proposed by de Villiers (2004, 2005 and 2007. This study reconciles a minimalist conception of language (CHOMSKY, 1995-2001 with the Syntactic Bootstrapping hypothesis (GLEITMAN, 1990. We report results of an experimental activity that consisted of 3 pre-tests and a classic FB task of location-change, applied to 24 children aged 3-4 and 5-6 years old. The results of the experiments reported here are compatible with the working hypothesis, namely, that the complementing syntax is not a sufficient condition for the establishment of FBs reasoning.

    Soraya da Rocha BRITTO

    Full Text Available ABSTRACT Objective: This study examined food product advertisements directed to children and aired on closed television channels in Brazil, according to the types of foods and beverages advertised and the advertising content. Methods: A descriptive study was conducted on the adequacy of food commercials directed to children and aired by six pay-television broadcasters according to two parameters: "The Food Guide for the Brazilian Population, 2014", and the National Council on Children's and Adolescents' Rights Resolution nº 163 of 2014 about food advertising. The advertisements were recorded in July 2015, at different times and days of the week. Results: One hundred and sixty-two hours were recorded, registering 3,468 commercials: 1,850 were related to internal programming and 1,618 advertised toys (22.15%, food and beverages (5.61%, applications for electronic devices (5.58%, and entertainment/events (5.56%. The Fisher exact test showed fewer number of food commercials compared to other types of commercials (p<0.001. The main food items advertised by all television stations were ultraprocessed foods and no advertisements of fresh food were observed (p<0.001. Most of the food commercials (64.30% used children's language and characters; 43.00% used songs in children's voices, and 21.40% linked gift distribution to food. Conclusion: The number of food commercials observed was lower than in previous national studies. However, the advertisements did not follow current legislation, indicating the abuse of marketing communication to children. More effective public policies and the respect and enforcement of legislation on child advertising could protect children from high consumption of ultraprocessed foods.

    The authors of the present article describe the historical context of family therapy in Poland and current issues in the field. They highlight the fact that Polish therapists first began to develop the field after coming into contact with family therapy leaders from the United States and Western Europe. With the political breakthrough of 1989, there were new opportunities for multilateral cooperation, attendance at international conferences, and the exchange of experiences. Currently, the work of Polish family therapists, the place of family therapy among other forms of psychotherapy, and the related problems and challenges do not differ from other European nations.

  6. Knowledge Transfer in Product Development: an Analysis of Brazilian Subsidiaries of Multinational Corporations

    Directory of Open Access Journals (Sweden)

    Dusan Schreiber

    2011-07-01

    Full Text Available Several studies about knowledge transfer in multinational corporations have found that the process is influenced by factors such as absorptive capacity, tacit knowledge and power relations, all of which impact knowledge sharing strategies between corporate headquarters and foreign subsidiaries. A multiple case study of Brazilian subsidiaries of three multinational corporations using in-depth interviews, based on a conceptual model consisting of four propositions, was conducted to identify factors linked to the knowledge transfer process and to assess their influence on that transfer. The first proposition tries to assess explicit knowledge, primarily through the use of IT tools; the second analyzes the role of the subsidiary within the corporate network and how it influences the degree of knowledge sharing. The third assesses the influence of subsidiary absorptive capacity and the fourth analyzes the impact of worker exchange programs on knowledge sharing between headquarters and foreign subsidiaries. Study results confirm the four propositions and enable the identification of relationships between factors, especially explicit knowledge and worker expatriation as complementary factors in knowledge transfer strategies.

    2012-01-01

    The operational diagnostic criteria for major depression have remained more or less the same in the past 40 years. However, the threshold for the diagnosis fixed by operational definitions has been criticized for either being too high, excluding many depressive states which do not differ from currently defined major depression on several variables, or too low, so that the milder cases receiving the diagnosis do not respond to antidepressants better than to placebo. Furthermore, it has been stated that current operational criteria do not convey anymore the gestalt of the depressive syndrome, and that they lead to the inclusion under the heading of depression of several homeostatic responses to adverse life events. This paper reviews the development and validation of the current concept of major depression and identifies priorities for future research. Copyright © 2012 S. Karger AG, Basel.

    To determine the association of single-nucleotide polymorphisms (SNPs) in genes related to craniofacial development, which were previously identified as susceptibility signals for nonsyndromic oral clefts, in Brazilians with nonsyndromic cleft lip and/or palate (NSCL/P). The SNPs rs748044 (TNP1), rs1106514 (MSX1), rs28372960, rs15251 and rs2569062 (TCOF1), rs7829058 (FGFR1), rs1793949 (COL2A1), rs11653738 (WNT3), and rs242082 (TIMP3) were assessed in a family-based transmission disequilibrium test (TDT) and a structured case-control analysis based on the individual ancestry proportions. The SNPs were initially analyzed by TDT, and polymorphisms showing a trend toward excess transmission were subsequently studied in an independent case-control sample. The study sample consisted of 189 case-parent trios of nonsyndromic cleft lip with or without cleft palate (NSCL±P), 107 case-parent trios of nonsyndromic cleft palate (NSCP), 318 isolated samples of NSCL±P, 189 isolated samples of NSCP, and 599 healthy controls. Association of alleles with NSCL/P pathogenesis. Preferential transmission of SNPs rs28372960 and rs7829058 in NSCL±P trios and rs11653738 in NSCP trios (P = .04) were observed, although the structured case-control analysis did not confirm these associations. The haplotype T-C-C formed by TCOF1 SNPs rs28372960, rs15251, and rs2569062 was more frequently transmitted from healthy parents to NSCL±P offspring, but the P value (P = .01) did not withstand Bonferroni correction for multiple tests. With the modest associations, our results do not support the hypothesis that TNP1, MSX1, TCOF1, FGFR1, COL2A1, WNT3, and TIMP3 variants are risk factors for nonsyndromic oral clefts in the Brazilian population.

    Saliva can be easily obtained in medical and non-medical settings, and contains numerous bio-molecules, including those typically found in serum for disease detection and monitoring. In the past two decades, the achievements of high-throughput approaches afforded by biotechnology and nanotechnology allow for disease-specific salivary biomarker discovery and establishment of rapid, multiplex, and miniaturized analytical assays. These developments have dramatically advanced saliva-based diagnostics. In this review, we discuss the current consensus on development of saliva/oral fluid-based diagnostics and provide a summary of recent research advancements of the Texas-Kentucky Saliva Diagnostics Consortium. In the foreseeable future, current research on saliva based diagnostic methods could revolutionize health care.

    Pharmacologic stress testing for myocardial perfusion imaging is a widely used noninvasive method for the evaluation of known or suspected coronary artery disease. The use of exercise for cardiac stress has been practiced for over 60 years and clinicians are familiar with its using. However, there are inevitable situations in which exercise stress is inappropriate. A large number of patients with cardiac problems are unable to exercise to their full potential due to comorbidity such as osteoarthritis, vascular disease and pulmonary disease and a standard exercise stress test for myocardial perfusion imaging is suboptimal means for assessment of coronary artery disease. This problem has led to the development of the pharmacologic stress test and to a great increase in its popularity. All of the currently used pharmacologic agents have well-documented diagnostic value. This review deals the physiological actions, clinical protocols, safety, nuclear imaging applications of currently available stress agents and future development of new vasodilating agents.

    Full Text Available Current needs for further development of Serbian legislation relate to the field of collective employee-employer relations and their collective rights and obligations. These are the relations established by the workers' and employers' mutually, but also the relationship between them, on the one hand and the state on the other. In other words, this is the need to strengthen the industrial democracies (including the improvement of labour legislation in the field of collective rights of employees and employers, which is actually still in stagnation. The fact is that trade union movement in Serbia, social dialogue, collective bargaining on working conditions, employees participation in management are weakening, which is where one should seek current needs for further development of labour law in order to strengthen and provide normatively the legal platform to stop these negative tendencies.

  12. The Challenge of Limiting Greenhouse Gas Emissions Through Activities implemented Jointly in Developing Countries: A Brazilian Perspective

    Energy Technology Data Exchange (ETDEWEB)

    La Rovere, E.L.

    1998-11-01

    This paper addresses, from the Brazilian perspective, the main problems with Joint Implementation/Activities Implemented Jointly (JI/AIJ) between industrialized (Annex I) and developing (non-Annex I) countries, as defined by the United Nations Framework Convention on Climate Change (UNFCCC). Four possible GHG emissions abatement measures are presented for Brazil: forest protection, reforestation projects for carbon sequestration or charcoal manufacturing, use of ethanol produced from sugar cane as a car fuel, and electrical energy conservation through an increase in end-use efficiencies. These four case studies form the basis of a discussion regarding the validity of developing countries' concerns about JI/AIJ. Recommendations are offered for overcoming the present shortcomings of JI/AIJ in developing countries. The primary conclusion is that Annex I countries' funding of JI/AIJ projects in developing countries in return for GHG emissions credits is not the best means to implement the UNFCCC. However, JI/AIJ projects can be a productive means of preventing global climate change if combined with other measures, including GHG emissions reduction targets for all countries involved in JI/AIJ projects and limits on the percentage of industrialized countries' emissions reductions that can be met through projects in developing countries.

    Tuberculosis (TB) continues to be a global health threat. BCG was developed as an attenuated live vaccine for tuberculosis control nearly a century ago. Despite being the most widely used vaccine in human history, BCG is not an ideal vaccine and has two major limitations: its poor efficacy against adult pulmonary TB and its disconcerting safety in immunocompromised individuals. A safer and more effective TB vaccine is urgently needed. This review article discusses current strategies to develop the next generation of TB vaccines to replace BCG. While some progresses have been made in the past decade, significant challenges lie ahead.

    Rabies is an infectious disease among humans and animals that remains incurable, despite its longstanding research history. The only way to prevent the disease is prompt treatment, including vaccination as an obligatory component and administration of antirabies immunoglobulin as a supplement. Since the first antirabies vaccination performed in the 19th century, a large number of different rabies vaccines have been developed. Progress in molecular biology and biotechnology enabled the development of effective and safe technologies of vaccine production. Currently, new-generation vaccines are being developed based on recombinant rabies virus strains or on the production of an individual recombinant rabies antigen-glycoprotein (G protein), either as a component of nonpathogenic viruses, or in plants, or in the form of DNA vaccines. In this review, the main modern trends in the development of rabies vaccines have been discussed.

    Anthropometric data are essential for the design of military equipment including sizing of aircraft cockpits and personal gear. Currently, there are no anthropometric databases specific to Brazilian military personnel. The aim of this study was to create a Brazilian anthropometric database of Air Force pilots. The methods, protocols, descriptions, definitions, landmarks, tools and measurements procedures followed the instructions outlined in Measurer's Handbook: US Army and Marine Corps Anthropometric Surveys, 2010-2011 - NATICK/TR-11/017. The participants were measured countrywide, in all five Brazilian Geographical Regions. Thirty-nine anthropometric measurements related to cockpit design were selected. The results of 2133 males and 206 females aged 16-52 years constitute a set of basic data for cockpit design, space arrangement issues and adjustments, protective gear and equipment design, as well as for digital human modelling. Another important implication is that this study can be considered a starting point for reducing gender bias in women's career as pilots. Practitioner Summary: This paper describes the first large-scale anthropometric survey of the Brazilian Air Force pilots and the development of the related database. This study provides critical data for improving aircraft cockpit design for ergonomics and comprehensive pilot accommodation, protective gear and uniform design, as well as digital human modelling.

    In Brazil, more than 99% of malaria cases are reported in the Amazon, and the State of Amazonas accounts for 40% of this total. However, the accumulated experience and challenges in controlling malaria in this region in recent decades have not been reported. Throughout the first economic cycle during the rubber boom (1879 to 1912), malaria was recorded in the entire state, with the highest incidence in the villages near the Madeira River in the Southern part of the State of Amazonas. In the 1970s, during the second economic development cycle, the economy turned to the industrial sector and demanded a large labor force, resulting in a large migratory influx to the capital Manaus. Over time, a gradual increase in malaria transmission was observed in peri-urban areas. In the 1990s, the stimulation of agroforestry, particularly fish farming, led to the formation of permanent Anopheline breeding sites and increased malaria in settlements. The estimation of environmental impacts and the planning of measures to mitigate them, as seen in the construction of the Coari-Manaus gas pipeline, proved effective. Considering the changes occurred since the Amsterdam Conference in 1992, disease control has been based on early diagnosis and treatment, but the development of parasites that are resistant to major antimalarial drugs in Brazilian Amazon has posed a new challenge. Despite the decreased lethality and the gradual decrease in the number of malaria cases, disease elimination, which should be associated with government programs for economic development in the region, continues to be a challenge.

    2017-01-01

    Toxoplasma gondii causes fatal and debilitating brain and eye diseases. Medicines that are currently used to treat toxoplasmosis commonly have toxic side effects and require prolonged courses that range from weeks to more than a year. The need for long treatment durations and the risk of relapsing disease are in part due to the lack of efficacy against T. gondii tissue cysts. The challenges for developing a more effective treatment for toxoplasmosis include decreasing toxicity, achieving therapeutic concentrations in the brain and eye, shortening duration, eliminating tissue cysts from the host, safety in pregnancy, and creating a formulation that is inexpensive and practical for use in resource-poor areas of the world. Over the last decade, significant progress has been made in identifying and developing new compounds for the treatment of toxoplasmosis. Unlike clinically used medicines that were repurposed for toxoplasmosis, these compounds have been optimized for efficacy against toxoplasmosis during preclinical development. Medicines with enhanced efficacy as well as features that address the unique aspects of toxoplasmosis have the potential to greatly improve toxoplasmosis therapy. This review discusses the facets of toxoplasmosis that are pertinent to drug design and the advances, challenges, and current status of preclinical drug research for toxoplasmosis.

    The monolithic alternating current light emitting diode (ACLED) has been revealed for several years and was regarded as a potential device for solid state lighting. In this study, we will discuss the characteristics, development status, future challenges, and ITRI's development strategy about ACLED, especially focusing on the development progress of the monolithic GaN-based Schottky barrier diodes integrated ACLED (SBD-ACLED). The SBD-ACLED design can not only improve the chip area utilization ratio but also provide much higher reverse breakdown voltage by integrating four SBDs with the micro-LEDs array in a single chip, which was regarded as a good on-chip ACLED design. According to the experimental results, higher chip efficiency can be reached through SBD-ACLED design since the chip area utilization ratio was increased. Since the principle and the operation condition of ACLED is quite different from those of the typical DCLED, critical issues for ACLED like the current droops, the flicker phenomenon, the safety regulations, the measurement standards and the power fluctuation have been studied for getting a practical and reliable ACLED design. Besides, the "AC LED application and research alliance" (AARA) lead by ITRI in Taiwan for the commercialization works of ACLED has also been introduced.

    The conduct of randomized controlled trials for vasculitis, especially for the antineutrophil cytoplasmic antibody-associated vasculitides [AAV, granulomatosis with polyangiitis (Wegener's) and microscopic polyangiitis], has been greatly advanced by the development, use, and acceptance of validated outcome measures. Trials have subsequently provided the opportunity to validate and refine reliable, valid outcome measures for these multisystemic and relapsing rare diseases. The Outcome Measures in Rheumatology (OMERACT) Vasculitis Working Group was formed in 2004 to foster development of validated and widely accepted outcomes in vasculitis using data-driven analyses, a dedication to building consensus, and adherence to, and guidance by, the principles of the OMERACT approach. This work led to the endorsement by OMERACT of the core set of domains and associated outcome measures for AAV. Next steps for the study of existing outcome tools in AAV include better definition of response criteria through development of more data-driven weighting of the elements of activity and damage assessment. The Working Group is now also embarking on a series of linked projects to develop validated patient-reported outcomes for use in clinical research in vasculitis. Additionally, the Working Group is studying how current methods of disease assessment and plans for new outcomes can be informed by the conceptual framework of the International Classification of Function of the World Health Organization. The success of the Group's work in AAV has also led to a formal process for developing outcomes for the large vessel vasculitides (Takayasu arteritis and giant cell arteritis) and Behçet disease.

    Full Text Available In North America, the use of the term ‘social pedagogy’ is a relatively new phenomenon, but social pedagogical practices have been used for a long time. The recent interest in the field of social pedagogy can be explained in part by the publication of an unprecedented volume of books and articles in English language, the creation of a new international journal, the simultaneous development of graduate programs in social pedagogy in the UK and the USA, and the establishment of a social pedagogy association that brings together academics and practitioners. In North America, social pedagogy thinking is influenced by the history of the field, by current social pedagogy theory and practice in other parts of the world, and by several traditions that connect education with social change. The paper discusses ten of them: indigenous education, progressive education, social movement learning, community development, public pedagogy, popular education, participatory action research, social economy, participatory democracy, and critical theory.

    Full Text Available Malformations of cortical development (MCD result from disruptions in the complex process of the human brain cortex formation and are highly associated to severe epilepsy, neurodevelopmental delay and motor dysfunction. Nowadays, magnetic resonance imaging (MRI is the cornerstone of the work-up of patients with epilepsy and modern advanced imaging techniques have improved not only our ability to detect and characterize cortical malformations, but also in identifying associated functional abnormalities that are far beyond the structural visualized lesions. Herein, we address the most currently used classifications of MCD and make a concise review of the embryological process of cortical development. Our main goal is to summarize recent advances and new trends in diagnostic imaging techniques concerning MCD. Thereafter, follows a brief discussion of specific disorders and their radiological features.

    TB persists as a global epidemic with high morbidity and mortality, especially in low-income countries. It is the only infectious disease ever declared as a global emergency by the WHO. The HIV pandemic and the emergence of drug resistance represent two additional obstacles to better control of the disease. Important progress has been made in the last decade in TB diagnostics. Major needs still exist, such as the availability of a real point-of-care test, a better diagnosis of TB in immune-compromised populations and in children, and the possibility to predict progression to disease in latently infected people. This review will summarize the current developments in TB diagnostics and the perspectives for future developments in the field.

    Respiratory syncytial virus (RSV) is the etiological agent for a serious lower respiratory tract disease responsible for close to 200,000 annual deaths worldwide. The first infection is generally most severe, while re-infections usually associate with a milder disease. This observation and the finding that re-infection risks are inversely associated with neutralizing antibody titers suggest that immune responses generated toward a first RSV exposure can significantly reduce morbidity and mortality throughout life. For more than half a century, researchers have endeavored to design a vaccine for RSV that can mimic or improve upon natural protective immunity without adverse events. The virus is herein described together with the hurdles that must be overcome to develop a vaccine and some current vaccine development approaches. PMID:23385470

    Highlights: • Design and R&D for DEMO TF conductors. • Wind&react vs. react&wind options for Nb{sub 3}Sn high grade TF conductors. • Progress in the manufacture of short length Nb{sub 3}Sn proptotypes. • Design and prototype manufacture for high current HTS cabled conductors. - Abstract: The large size of the magnets for DEMO calls for very large operating current in the forced flow conductor. A plain extrapolation from the superconductors in use for ITER is not adequate to fulfill the technical and cost requirements. The proposed DEMO TF magnets is a graded winding using both Nb{sub 3}Sn and NbTi conductors, with operating current of 82 kA @ 13.6 T peak field. Two Nb{sub 3}Sn prototypes are being built in 2014 reflecting the two approaches suggested by CRPP (react&wind method) and ENEA (wind&react method). The Nb{sub 3}Sn strand (overall 200 kg) has been procured at technical specification similar to ITER. Both the Nb{sub 3}Sn strand and the high RRR, Cr plated copper wire (400 kg) have been delivered. The cabling trials are carried out at TRATOS Cavi using equipment relevant for long length production. The completion of the manufacture of the two 20 m long prototypes is expected in the end of 2014 and their test is planned in 2015 at CRPP. In the scope of a long term technology development, high current HTS conductors are built at CRPP and ENEA. A DEMO-class prototype conductor is developed and assembled at CRPP: it is a flat cable composed of 20 twisted stacks of coated conductor tape soldered into copper shells. The 10 kA conductor developed at ENEA consists of stacks of coated conductor tape inserted into a slotted and twisted Al core, with a central cooling channel. Samples have been manufactured in industrial environment and the scalability of the process to long production lengths has been proven.

    2012-01-01

    Antibiotics and vaccines are the two most successful medical countermeasures that humans have created against a number of pathogens. However a select few e.g., Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis (TB) have evaded eradication by vaccines and therapeutic approaches. TB is a global public health problem that kills 1.4 million people per year. The past decade has seen significant progress in developing new vaccine candidates, but the most fundamental questions in understanding disease progression and protective host responses that are responsible for controlling Mtb infection still remain poorly resolved. Current TB treatment requires intense chemotherapy with several antimicrobials, while the only approved vaccine is the classical viable whole-cell based Bacille-Calmette-Guerin (BCG) that protects children from severe forms of TB, but fails to protect adults. Taken together, there is a growing need to conduct basic and applied research to develop novel vaccine strategies against TB. This review is focused on the discussion surrounding current strategies and innovations being explored to discover new protective antigens, adjuvants, and delivery systems in the hopes of creating an efficacious TB vaccine.

    The report aims at presenting the overall state of grouting competence and development relating to the final repository and at motivating and giving detail to the grouting sections presented in the 2007 version of the overall SKB report 'Programme for research, development and demonstration of methods for the management and disposal of nuclear waste' that is presented to the government every three years. The report offers suggestions for principles for planning, design and execution of grouting and describes the further work thought to be necessary in order to meet the requirements of the final repository, that are currently given as working premises. This report does not aim to, and cannot, describe the grouting processes in detail. For details of current concepts, experience and development work, a list of references is provided. In Chapter 2, the task of sealing the underground repository is examined and an overall approach presented. Although the requirements related to this task are preliminary, it is made evident that they concern both the actual grouting results and the process leading to the achievement of these results. Chapter 3 is a conceptual description of grouting and the factors that govern the spreading of grout in the rock mass. It is intended as an introduction to Chapters 4-6, which describe the state of grouting competence and the tools available for the sealing of the final repository facility. Both common practice and cutting-edge research are dealt with in these chapters, mainly relying on references where available. Chapters 4 and 5 focus on the system consisting of the fundamental components the rock mass, the grout materials and the grouting technology, and how these system components interact whilst, in Chapter 6, the rock/grout technical system is viewed in a brief organizational context. Based on the requirements on results and the overall grouting process on the one hand and the current competence in grouting theory and

    Full Text Available This work presents an overview of the development of analytical chemistry in Brazil in the last 25 years under the influence of Brazilian Chemical Society (SBQ. It is shown that the common sense that analytical chemistry is still an under-developed area is not true. Data from specialized literature show a significant contribution of Brazilian analytical chemists in high impact periodicals and for several areas there is a good adherence among works carried out in Brazil and abroad according to a comparison of studies presented in the 11th Brazilian Meeting on Analytical Chemistry (Campinas, September, 2001 and the XI European Conference on Analytical Chemistry (Lisboa, September, 2000. According to the opinion of investigators in this area, there are some topics that require a focused attention for proper evolution. However, there is an absolute consensus about the evolution of graduate programs and the need to improve and extend strategies to absorb newcomers in the area. Some suggestions are presented considering possible pathways of analytical chemistry in Brazil.

    2013-01-01

    Stereotactic ablative radiotherapy (SABR) has developed from the principles and techniques used in the stereotactic radiosurgery treatment of brain metastases. Advances in computer technology, imaging, planning and treatment delivery and evidence from retrospective analysis of single- and multi-institutional early-phase studies have established SABR in the treatment of medically inoperable early lung cancer. Effective multidisciplinary team working is crucial to safe delivery of SABR. The variation in patient selection, radiotherapy planning and delivery techniques has led to a collective approach to SABR implementation across the UK. Centres developing the technique are represented in the UK SABR Consortium, which is supported by the relevant UK professional bodies and represents a platform to develop extracranial SABR across the UK. The uptake of SABR in the UK has been slowed by workforce issues, but at least 15 centres are currently delivering treatment with over 500 patients treated using UK SABR Consortium guidance. A mentoring program is being piloted helping new centres to develop their programs, and over 30 UK centres are expected to be offering SABR treatment by the end of 2014. The use of consistent guidance for patient selection, treatment planning and delivery in the UK gives the opportunity to collect and audit toxicity and outcome across the centres, contributing to the internationally reported SABR experience. Having established this service in the UK, the development of SABR through clinical research is a priority, and with input from the Radiotherapy Trials Quality Assurance Group, the UK is developing a national study program that includes participation in international trials.

    Every year, hundreds of thousands of students and teachers from all over the country take part in the Brazilian Olympiad of Astronomy and Astronautics (OBA). This has the aim of both spreading astronomy and astronautics-related concepts and training teachers about these topics. After being marked some of the exams are sent by participant schools to the Organizing Committee to select candidates for the international competition. The OBA exam archive thereby offers an unique opportunity to evaluate the teaching of astronomy in Brazil in relation to school level and content, as well as over time. Understanding the misconceptions unraveled by the exams is of utmost importance to planning successful outreach activities. In this talk I will present how the analysis of the 2013 OBA event helped the Museum of Astronomy and Related Sciences to develop an astronomy education kit aimed at teachers and how this cooperation between an academic institution and schools is helping educators in their pedagogical practice to teach astronomy in the classroom.

    Full Text Available This article aims to reflect on the history of the practices of ombudsmen in the Brazilian and Portuguese media, seeking simultaneously to identify the challenges and difficulties inherent to this function in mediatic communication. A comparative approach is adopted here, which, as is generally the case in social science, seeks to discover regularities and recognize differences in the activities developed by the ombudsmen in Brazil and Portugal between 1989 and 2013. Hence, using comparison to obtain a method to objectify the analysis, this study purports to outline the function in communication vehicles in both countries. With almost 25 years’ existence in the lusophone sphere and, despite having properties such as the accountability mechanism, hetero- and auto-regulation, the ombudsman has not been widely adopted in Portuguese-speaking countries. In Brazil, the expansion of the function is still conceivable, while in Portugal, the ombudsman is an instrument undergoing steady decline. Affected by the European economic crisis, the Portuguese media have resisted the establishment of the institution  and those who have already accepted it seem to be abandoning it progressively.

    Full Text Available This article examines the influence of the translation in the formation of cultural identities, following a text of Lawrence Venuti, in which he explains the process of translation and its effects, the representation of foreign cultures and the creation of domestic subjects, and argues on the ethics of translation under the ethnocentric perspective. Based on the teachings of Venuti, this paper presents the example of the influence of some Brazilian texts in international terminology referring to the first of the eight Millennium Development Goals - “eradicate hunger and extreme poverty.” The emphasis of the article is mainly on the influence that translation can have in collective identities, when it is authorized and supported by institutions. Moreover, it ascertains, under a contrastive perspective to the Venuti’s text, that in the Presidency of the Federative Republic of Brazil the translator does not choose the texts to be translated, and translations published by that institution do not mention their authorship.

    This milestone report covers the progress and status of Corsica modeling for DIII-D experiments over the past year, since our previous report in September, 1995. During this time, we have concentrated on improvements to the code in support of our ability to do self-consistent, predictive modeling of DIII-D discharges. Our interest is in obtaining a tool, benchmarked with experimental data, for developing advanced tokamak operations scenarios including simulation and analysis of high performance negative central shear (NCS) discharges and control of the current profile evolution. Our major focus has been on installing and improving the neutral beam current drive mode in Corsica; this element is critical to modeling the evolution of DIII-D discharges. The NFREYA neutral beam deposition code was installed (starting with a version consistent with GA`s ONETWO code) and the capability for following particle orbits, including the effects of drifts, was added for determining the current driven by neutral beam -injection. In addition, improved methods for more easily integrating experimental profile measurements into the code operation and for calculating Z{sub eff} either from models or from impurity density measurements have been added. We have recently begun to turn on various transport models in our simulation of discharge evolution. We have concentrated on the NCS configuration and have simulated the evolution of two different high neutron reactivity discharges; an NCS discharge with L-mode edge and a single- null, weak NCS discharge from the JET/ITER/DIII-D equivalent shape experiments. Corsica simulation results for these discharges were presented at the EPS meeting in Kiev, Ukraine in June, 1996.

    Accurate diagnosis of Helicobacter pylori (H. pylori) infection is a crucial part in the effective management of many gastroduodenal diseases. Several invasive and non-invasive diagnostic tests are available for the detection of H. pylori and each test has its usefulness and limitations in different clinical situations. Although none can be considered as a single gold standard in clinical practice, several techniques have been developed to give the more reliable results. Invasive tests are performed via endoscopic biopsy specimens and these tests include histology, culture, rapid urease test as well as molecular methods. Developments of endoscopic equipment also contribute to the real-time diagnosis of H. pylori during endoscopy. Urea breathing test and stool antigen test are most widely used non-invasive tests, whereas serology is useful in screening and epidemiological studies. Molecular methods have been used in variable specimens other than gastric mucosa. More than detection of H. pylori infection, several tests are introduced into the evaluation of virulence factors and antibiotic sensitivity of H. pylori, as well as screening precancerous lesions and gastric cancer. The aim of this article is to review the current options and novel developments of diagnostic tests and their applications in different clinical conditions or for specific purposes. PMID:26523098

    Current Ebola virus outbreak in West Africa already reached the total number of 1,323 including 729 deaths by July 31st. the fatality is around 55% in the southeastern area of Guinea, Sierra Leone, Liberia, and Nigeria. The number of patients with Ebola Hemorrhagic Fever (EHF) was continuously increasing even though the any effective therapeutics or vaccines has not been developed yet. The Ebola virus in Guinea showed 98% homology with Zaire Ebola Virus. Study of the pathogenesis of Ebola virus infection and assess of the various candidates of vaccine have been tried for a long time, especially in United States and some European countries. Even though the attenuated live vaccine and DNA vaccine containing Ebola viral genes were tested and showed efficacy in chimpanzees, those candidates still need clinical tests requiring much longer time than the preclinical development to be approved for the practical treatment. It can be expected to eradicate Ebola virus by a safe and efficient vaccine development similar to the case of smallpox virus which was extinguished from the world by the variola vaccine.

    Full Text Available The importance of harmonization of accounting atandards is now widely accepted all over the world. The increased international movement of investments has strongly forces the harmonization of the various national accounting standards in a uniform financial reporting system accepted worldwide. Recently the Securities and Exchange Commission has agreed to remove the requirement international firms reporting under International Financial Reporting Standards (IFRS and listed in the U.S to provide reconciliation to U.S. Generally Accepted Accounting Principles (GAAP. This recent move of the Securities and Exchange Commission indicate that U.S. financial reporting is likely to converge with IFRS in the near future. The International Accounting Standards Board (IASB and the Financial Accounting Standards Board (FASB are currently working together so as to converge their existing accounting standards into a common set of international accounting standards. The objective of this paper is to discuss the FASB and IASB convergence process by addressing current developments regarding significant topics that were deemed critical to this convergence. The convergence of GAAP and IFRS seems inevitable. Mixed opinions have been voiced about this convergence process. Many have begun to consider obstacles that is possible to lay ahead as well as the possible costs and benefits of such a move to the IFRS .

    Full Text Available Commercial surgical robots have been in clinical use since the mid-1990s, supporting surgeons in various tasks. In the past decades, many systems emerged as research platforms, and a few entered the global market. This paper summarizes the currently available surgical systems and research directions in the broader field of surgical robotics. The widely deployed teleoperated manipulators aim to enhance human cognitive and physical skills and provide smart tools for surgeons, while image-guided robotics focus on surpassing human limitations by introducing automated targeting and treatment delivery methods. Both concepts are discussed based on prototypes and commercial systems. Through concrete examples the possible future development paths of surgical robots are illustrated. While research efforts are taking different approaches to improve the capacity of such systems, the aim of this survey is to assess their maturity from the commercialization point of view.

    2012-12-07

    Endohedral metallofullerenes (EMFs), a new class of hybrid molecules formed by encapsulation of metallic species inside fullerene cages, exhibit unique properties that differ distinctly from those of empty fullerenes because of the presence of metals and their hybridization effects via electron transfer. This critical review provides a balanced but not an exhaustive summary regarding almost all aspects of EMFs, including the history, the classification, current progress in the synthesis, extraction, isolation, and characterization of EMFs, as well as their physiochemical properties and applications in fields such as electronics, photovoltaics, biomedicine, and materials science. Emphasis is assigned to experimentally obtained results, especially the X-ray crystallographic characterizations of EMFs and their derivatives, rather than theoretical calculations, although the latter has indeed enhanced our knowledge of metal-cage interactions. Finally, perspectives related to future developments and challenges in the research of EMFs are proposed. (381 references).

    Full Text Available Rehabilitation services are set to become central to modern health care systems as they strive to support an increasingly ageing population to live as independently as possible, while maintaining quality services. Alternative service delivery options such as telerehabilitation may assist in meeting the growing demand for services and many countries are exploring the potential use of telerehabilitation within their health care systems. The Scottish Centre for Telehealth commissioned an independent scoping study and subsequent report into the potential development and realisation of telerehabilitation services across Scotland. The scope of the report was restricted to adult rehabilitation services and aimed to identify opportunities for the use of telerehabilitation and to recommend clear and achievable steps towards implementation of telerehabilitation. This article outlines some of the telerehabilitation initiatives currently underway in Scotland and discusses some of the key recommendations made in the report to the Scottish Centre for Telehealth for the future advancement and application of telerehabilitation across Scotland.

    Full Text Available Chronic constipation is a common gastrointestinal disease severely affecting the patient׳s quality of life. The traditional treatment of constipation is the use of laxatives. Recently, several new drugs including lubiprostone, linaclotide and prucalopride have been approved for treatment of chronic constipation. However, a significant unmet medical need still remains, particularly among those patients achieving poor results by current therapies. The 5-HT4 receptor modulators velusetrag and naronapride, the guanylate cyclase C agonist plecanatide and the ileal bile acid transporter inhibitor elobixibat are recognized as the most promising drugs under investigation. Herein, we give a comprehensive review on the pharmacological therapeutics for the treatment of chronic constipation, with the purpose of reflecting the drug development trends in this field.

    Fabrication of high T{sub c} superconductors and its applications for electric power device were carried out for developing superconductor application technologies. High quality YBCO superconductors was fabricated by melt texture growth, top-seeded melt growth process and multi-seeded melt growth process and the properties was compared. The critical current density of the melt processed YBCO superconductors was about few 10,000 A/cm{sup 2} and the levitation force was 50 N. The processing time needed for the growth of the 123 single grain was greatly reduced by applying multi-seeding without no significant degradation of the levitation force. The multi-seeded melt growth process was confirmed as a time-saving and cost-effective method for the fabrication of bulk superconductors with controlled crystallographic orientation.

    Non-small-cell lung cancer (NSCLC) is a highly prevalent and aggressive disease. In the metastatic setting, major advances include the incorporation of immunotherapy and targeted therapies into the clinician's therapeutic armamentarium. Standard chemotherapeutic regimens have long been reported to interfere with the immune response to the tumor; conversely, antitumor immunity may add to the effects of those therapies. The aim of immunotherapy is to specifically enhance the immune response directed to the tumor. Recently, many trials addressed the role of such therapies for metastatic NSCLC treatment: ipilimumab, tremelimumab, nivolumab and lambrolizumab are immunotherapeutic agents of main interest in this field. In addition, anti-tumor vaccines, such as MAGE-A3, Tecetomide, TG4010, CIMAvax, ganglioside vaccines, tumor cell vaccines and dendritic cell vaccines, emerged as potent inducers of immune response against the tumor. The current work aims to address the most recent developments regarding these innovative immunotherapies and their implementation in the treatment of metastatic NSCLC.

    The Dortmund Low Background Facility (DLB) is a low-background gamma ray spectrometry system with an artificial overburden. The overburden of ten meters of water equivalent, in combination with a multi-layer lead castle and an active muon veto are shielding a high-purity germanium detector of 60 % relative efficiency. The background level is remarkably low compared to a conventional spectrometer system without special shielding and enables sensitivities well below 1 Bq/kg. Thus, material screening measurements as well as environmental monitoring measurements are possible on an easy-accessible location above ground at the campus of the Technische Universitaet Dortmund. The integral background count rate between 40 keV and 2700 keV is 2.528±0.004 counts/kg/min, which is comparable to systems that are situated below ground. In the talk, an overview of the current status of the DLB is given and recent developments are presented.

    Full Text Available This work makes an analysis of the determinants of Corporate Social Responsibility (CSR of Brazilian firms, as proxied by firm membership of the ISE Index of BM&FBOVESPA. Besides other proposed determinants of CSR present in the literature (firm size, profitability, growth opportunities, the work examines ownership concentration and the persistence on CSR status. Logit regression estimates have been run for a sample of 1649 firm-year observations in the period 2006-2011. The findings show that CSR of Brazilian firms is inversely correlated to its ownership concentration indicating that controlling voting shareholders may not see social concerns as a priority. Besides, firms tend to maintain their present CSR status. The results also indicate that leading CSR firms are larger, face more growth opportunities, and are persistent in their superior CSR situation.

  13. Malaria in the State of Amazonas: a typical Brazilian tropical disease influenced by waves of economic development

    Full Text Available In Brazil, more than 99% of malaria cases are reported in the Amazon, and the State of Amazonas accounts for 40% of this total. However, the accumulated experience and challenges in controlling malaria in this region in recent decades have not been reported. Throughout the first economic cycle during the rubber boom (1879 to 1912, malaria was recorded in the entire state, with the highest incidence in the villages near the Madeira River in the Southern part of the State of Amazonas. In the 1970s, during the second economic development cycle, the economy turned to the industrial sector and demanded a large labor force, resulting in a large migratory influx to the capital Manaus. Over time, a gradual increase in malaria transmission was observed in peri-urban areas. In the 1990s, the stimulation of agroforestry, particularly fish farming, led to the formation of permanent Anopheline breeding sites and increased malaria in settlements. The estimation of environmental impacts and the planning of measures to mitigate them, as seen in the construction of the Coari-Manaus gas pipeline, proved effective. Considering the changes occurred since the Amsterdam Conference in 1992, disease control has been based on early diagnosis and treatment, but the development of parasites that are resistant to major antimalarial drugs in Brazilian Amazon has posed a new challenge. Despite the decreased lethality and the gradual decrease in the number of malaria cases, disease elimination, which should be associated with government programs for economic development in the region, continues to be a challenge.

  16. Current issues of RNAi therapeutics delivery and development.

    Haussecker, D

    2014-12-10

    12 years following the discovery of the RNAi mechanism in Man, a number of RNAi therapeutics development candidates have emerged with profiles suggesting that they could become drugs of significant medical importance for diseases like TTR amyloidosis, HBV, solid cancers, and hemophilia. Despite this robust progress, the perception of RNAi therapeutics has been on a roller-coaster ride driven not only by science, but also regulatory trends, the stock markets, and Big Pharma business development decisions [1]. This presentation provides an update on the current state of RNAi therapeutics development with a particular focus on what RNAi delivery can achieve today and key challenges to be overcome to expand therapeutic opportunities. The delivery of RNAi triggers to disease-relevant cell types clearly represents the rate-limiting factor in broadly expanding the applicability of RNAi therapeutics. Today, with at least 3 delivery options (lipid nanoparticles/LNPs, GalNAc-siRNA conjugates, Dynamic PolyConjugates/DPCs) for which profound gene knockdowns have been demonstrated in non-human primates and in the clinic, RNAi therapeutics should in principle be able to address most diseases related to gene expression in the liver. Given the central importance of the liver in systemic physiology, this already represents a significant therapeutic and commercial opportunity rivaling that of e.g. monoclonal antibodies. Beyond the liver, there is a reason to believe that current RNAi therapeutics technologies can address a number of solid tumors (e.g. LNPs), diseases of the eye (e.g. self-delivering RNAi triggers) as well as diseases involving the respiratory epithelium (e.g. aerosolized LNPs), certain phagocytic cells (LNPs), hematopoietic stem cells and their progeny (lentiviral DNA-directed RNAi), vascular endothelial cells (cationic lipoplexes), and certain cell types in the kidney (self-delivering RNAi triggers, DPCs; Table 1). Despite this success, there has been a sense that

    Infant developmental delays have been associated with several risk factors, such as familial environmental, individual and demographic characteristics. The goal of this study was to longitudinally investigate the effects of maternal knowledge and practices, home environment and biological factors on infant motor and cognitive outcomes. This was a prospective cohort study with a sample of 49 infants from Southern Brazil. The infants were assessed three times over 4 months using the Alberta Infant Motor Scale and the Bayley Scale of Infant Development (Mental Development Scale). Parents completed the Daily Activities Scale of Infants, the Affordances in The Home Environment for Motor Development - Infant Scale, the Knowledge of Infant Development Inventory and a demographic questionnaire. Generalized estimating equation with Bonferroni method as the follow-up test and Spearman correlation and multivariate linear backward regression were used. Cognitive and motor scores were strongly associated longitudinally and increased over time. Associations between the home affordances, parental practices and knowledge, and motor and cognitive development over time were observed. This relationship explained more variability in motor and cognitive scores compared with biological factors. Variability in motor and cognitive development is better explained by environment and parental knowledge and practice. The investigation of factors associated with infant development allows the identification of infants at risk and the implementation of educational programs and parental training to minimize the effects of developmental delay. © 2016 Japan Pediatric Society.

    Food contamination by pathogenic microorganisms has been a serious public health problem and a cause of huge economic losses worldwide. Foodborne pathogenic Escherichia coli (E. coli) contamination, such as that with E. coli O157 and O104, is very common, even in developed countries. Bacterial contamination may occur during any of the steps in the farm-to-table continuum from environmental, animal, or human sources and cause foodborne illness. To understand the causes of the foodborne outbreaks by E. coli and food-contamination prevention measures, we collected and investigated the past 10 years' worldwide reports of foodborne E. coli contamination cases. In the first half of this review article, we introduce the infection and symptoms of five major foodborne diarrheagenic E. coli pathotypes: enteropathogenic E. coli (EPEC), Shiga toxin-producing E. coli/enterohemorrhagic E. coli (STEC/EHEC), Shigella/enteroinvasive E. coli (EIEC), enteroaggregative E. coli (EAEC), and enterotoxigenic E. coli (ETEC). In the second half of this review article, we introduce the foodborne outbreak cases caused by E. coli in natural foods and food products. Finally, we discuss current developments that can be applied to control and prevent bacterial food contamination.

  19. Development and regulation of biosimilars: current status and future challenges.

    2013-06-01

    Biologic medicinal products developed via rDNA technology as recombinant protein-based medicines that have been in clinical use since the early 1980s as original biopharmaceuticals have greatly contributed to the therapy of severe metabolic and degenerative diseases. The recent expiration of the data protection or patents for most of them created opportunities for the development of copy versions of original biopharmaceuticals with similar biologic activity (termed biosimilars). Production of these new products is expected to meet worldwide demand, promote market competition, maintain the incentives for innovation, and sustain the healthcare systems. The licencing of these products, however, relies on the experience gained with the original biopharmaceuticals. Critical issues related to this class of medicinal products include their terminology (to avoid confusion with generics and non-innovator copy versions that have not been tested according to the biosimilar guidelines), manufacturing, and regulation. The European Union (EU) has been the first to establish a regulatory framework for marketing authorization application (MAA) and has named these products biosimilars, a term also recently adopted by the US FDA. Unlike the conventional, more common small molecular weight human medicines and chemical generics, protein-based medicines exhibit higher molecular weight, complexity in structure and function that can be affected by changes in the manufacturing process. Therefore, biosimilars represent a relatively heterogeneous class of medicinal products that make their regulation quite challenging. According to the current understanding in the EU, a biosimilar is a copy version of an already authorized biopharmaceutical (or reference product) with similar biologic activity, physicochemical characteristics, efficacy, and safety, based on a full comparability exercise at quality, preclinical and clinical level to ensure similar efficacy and safety. Guidance has been

    2017-01-01

    Psoriasis is a chronic and complex autoimmune inflammatory skin disease that affects over 125 million people worldwide. It can exhibit at any age, in spite of the fact that children are less normally influenced than adults. It is characterized by distinct erythematous plaques shielded with conspicuous silvery scales that shows up in different areas of the skin. Knowledge of pathophysiology, especially the pathogenesis of psoriasis, has significantly progressed in the recent decade. Advancement in molecular knowledge leads to better understanding of the disease, thus influencing the development of efficient treatment modalities. However, even with the availability of various options of treatment most of the efficient treatment modalities are costly. Expenses of health care bring about major financial weight to the patients as well as to health care systems. Thus, it was important to review the available current treatment options and those which are under development, in terms of efficacy, safety and cost to assist in selecting the most appropriate treatment for psoriasis patients. Literatures were searched by using key words psoriasis, topical treatment, systemic treatment, biologics and phototherapies, on Embase, Medline, Jstor, Cochrane and Merck Index databases. Life-style choices such as smoking, alcohol consumption, obesity and stress are recognised as risk factors and triggers associated with psoriasis. Psoriasis poses psycho-social and economic burden on affected patients that sometimes leads to depression, reduced social interaction and suicidal tendencies in patients. Depending on the type, severity and extent of the disease, comorbidities, patient preference, efficacy and safety profile, numerous treatment modalities and therapeutic agents are available such as topical, systemic, biologic and phototherapeutic treatments. However, it was found that among all the current available treatments for psoriasis, biologic agents and phototherapeutic modalities are

    WERNER, Patricia Ulson Pizarro

    2015-07-01

    Full Text Available This study presents a reflection on the position of the Brazilian Judicial Branch in recognizing joint liability of government entities in providing services as part of the Brazilian National Publich Health Systems (SUS. This study aims to demonstrate the need to avoid general-izing this interpretation in cases of judicial actions that have the power to change public policy. The question of joint liability should not be considered only from the procedural angle, but conversely, in terms of the fact that the federal government cannot continue to meet demands alone. In light of these unquestionable limitations in terms of the budget, human resources, and structure, strengthening institutional dialog will create a consistent, transparent, and improved system and it will stimulate the legitimate and long-lasting development of public health policies.

    Worldwide, tuberculosis (TB) remains the most frequent and important infectious disease causing morbidity and death. One-third of the world's population is infected with Mycobacterium tuberculosis (MTB), the etiologic agent of TB. The World Health Organization estimates that about eight to ten million new TB cases occur annually worldwide and the incidence of TB is currently increasing. In this context, TB is in the top three, with malaria and HIV being the leading causes of death from a single infectious agent, and approximately two million deaths are attributable to TB annually. In particular, pulmonary TB, the most common form of TB, is a highly contagious and life-threatening infection. Moreover, enhanced susceptibility to TB in HIV-infected populations is another serious health problem throughout the world. In addition, multidrug-resistant TB (MDR-TB) has been increasing in incidence in many areas, not only in developing countries but industrialized countries as well, during the past decade. These situations, particularly the global resurgence of TB and the rapid emergence of MDR-TB, underscore the importance of the development of new antituberculous drugs and new protocols for efficacious clinical control of TB patients using ordinary antimycobacterial drugs. Concerning the development of new antituberculous drugs, the following points are of particular importance. (1) Development of drugs which display lasting antimycobacterial activity in vivo is desirable, since they can be administered with long intervals and consequently facilitate directly observed therapy and enhance patient compliance. (2) Development of novel antituberculosis compounds to combat MDR-TB is urgently needed. (3) The eradication of slowly metabolizing and, if possible, dormant populations of MTB organisms that cause relapse, using new classes of anti-TB drugs is very promising for prevention of TB incidence, because it will markedly reduce the incidence of active TB from persons who are

    Flowers, the reproductive structures of the approximately 400 000 extant species of flowering plants, exist in a tremendous range of forms and sizes, mainly due to developmental differences involving the number, arrangement, size and form of the floral organs of which they consist. However, this tremendous diversity is underpinned by a surprisingly robust basic floral structure in which a central group of carpels forms on an axis of determinate growth, almost invariably surrounded by two successive zones containing stamens and perianth organs, respectively. Over the last 25 years, remarkable progress has been achieved in describing the molecular mechanisms that control almost all aspects of flower development, from the phase change that initiates flowering to the final production of fruits and seeds. However, this work has been performed almost exclusively in a small number of eudicot model species, chief among which is Arabidopsis thaliana. Studies of flower development must now be extended to a much wider phylogenetic range of flowering plants and, indeed, to their closest living relatives, the gymnosperms. Studies of further, more wide-ranging models should provide insights that, for various reasons, cannot be obtained by studying the major existing models alone. The use of further models should also help to explain how the first flowering plants evolved from an unknown, although presumably gymnosperm-like ancestor, and rapidly diversified to become the largest major plant group and to dominate the terrestrial flora. The benefits for society of a thorough understanding of flower development are self-evident, as human life depends to a large extent on flowering plants and on the fruits and seeds they produce. In this preface to the Special Issue, we introduce eleven articles on flower development, representing work in both established and further models, including gymnosperms. We also present some of our own views on current trends and future directions of the

    Protected areas are the leading forest conservation policy for species and ecoservices goals and they may feature in climate policy if countries with tropical forest rely on familiar tools. For Brazil's Legal Amazon, we estimate the average impact of protection upon deforestation and show how protected areas' forest impacts vary significantly with development pressure. We use matching, i.e., comparisons that are apples-to-apples in observed land characteristics, to address the fact that protected areas (PAs) tend to be located on lands facing less pressure. Correcting for that location bias lowers our estimates of PAs' forest impacts by roughly half. Further, it reveals significant variation in PA impacts along development-related dimensions: for example, the PAs that are closer to roads and the PAs closer to cities have higher impact. Planners have multiple conservation and development goals, and are constrained by cost, yet still conservation planning should reflect what our results imply about future impacts of PAs.

    Web-based interventions for smoking cessation available in Portuguese do not adhere to evidence-based treatment guidelines. Besides, all existing web-based interventions are built on proprietary platforms that developing countries often cannot afford. We aimed to describe the development of "Viva sem Tabaco", an open-source web-based intervention. The development of the intervention included the selection of content from evidence-based guidelines for smoking cessation, the design of the first layout, conduction of 2 focus groups to identify potential features, refinement of the layout based on focus groups and correction of content based on feedback provided by specialists on smoking cessation. At the end, we released the source-code and intervention on the Internet and translated it into Spanish and English. The intervention developed fills gaps in the information available in Portuguese and the lack of open-source interventions for smoking cessation. The open-source licensing format and its translation system may help researchers from different countries deploying evidence-based interventions for smoking cessation.

    Full Text Available The paper is concerned with the problem of preschool education in Russia and the Vologda region. It shows that in the current context of shortage of places in state nurseries it is necessary to develop private care service providers. Day-care is in great demand among parents having children at the ages from 1 to 3. The paper analyses the main characteristics of preschool educational organi-zations. It shows that in the Vologda region, particularly in Vologda, private demand for preschool education service is to a wide extent unsatisfied. In Vologda more than ten thousand children are on waiting lists for preschool educational organizations. In total, in the Vologda region the list numbers about 28.9 thousand children, 34% of them are registered in Vologda. The paper provides the results of the study into Vologda private nurseries and day-care carried out in May-June 2015 by using the method of involved observation. It reveals key factors hampering growth of private nurseries.It is noted that one of the factors is the lack of license for educational activities and motivation for most entrepreneurs to obtain it. The results show that unlicensed gardens are not controlled by the authorities and public organizations. Interaction between the private institutions of pre-school education is not provided as well. We can observe that some private sector organizations do not meet the requirement of health and safety standards and impose limiting measures for the sake of children health such as organization of walks due to the absence of a secure walking site. High amount of parental fee is also found out.It offers directions for the development of private preschool education service

    Our approach to prokaryotic single-cell Whole Genome Amplification at the JGI continues to evolve. To increase both the quality and number of single-cell genomes produced, we explore all aspects of the process from cell sorting to sequencing. For example, we now utilize specialized reagents, acoustic liquid handling, and reduced reaction volumes eliminate non-target DNA contamination in WGA reactions. More specifically, we use a cleaner commercial WGA kit from Qiagen that employs a UV decontamination procedure initially developed at the JGI, and we use the Labcyte Echo for tip-less liquid transfer to set up 2uL reactions. Acoustic liquid handling also dramatically reduces reagent costs. In addition, we are exploring new cell lysis methods including treatment with Proteinase K, lysozyme, and other detergents, in order to complement standard alkaline lysis and allow for more efficient disruption of a wider range of cells. Incomplete lysis represents a major hurdle for WGA on some environmental samples, especially rhizosphere, peatland, and other soils. Finding effective lysis strategies that are also compatible with WGA is challenging, and we are currently assessing the impact of various strategies on genome recovery.

    Clinical pharmacology in Russia has long history and is currently active, but rather unrecognized internationally. It is governmentally approved as a teaching/scientific specialty since 1983 and as a medical specialty since 1997. Courses of clinical pharmacology are included in the undergraduate curricula in the 5th and/or 6th year of education at all medical schools in the Russian Federation. Postgraduate education includes initial specialization in internal medicine with further residency in clinical pharmacology. Governmental legislation recommends that every healthcare institution has either a department or a single position of clinical pharmacologist. Major routine duties include information about and monitoring of medication use, consultations in difficult clinical situations, pharmacogenetic counseling, therapeutic drug monitoring, pharmacovigilance, and participation in drug and therapeutics (formulary) committees. There are official experts in clinical pharmacology in Russia responsible for coordinating relevant legislative issues. The chief expert clinical pharmacologist represents the discipline directly at the Ministry of Health. Research in clinical pharmacology in Russia is extensive and variable, but only some of it is published internationally. Russia is a participant of international societies of clinical pharmacology and therapeutics and collaboration is actively ongoing. There are still certain problems related to the development of the discipline in Russia-some healthcare institutions do not see the need for clinical pharmacology. However, the number of clinical pharmacologists in Russia is increasing as well as their role in physicians' education, national healthcare, and research.

    Full Text Available Biofuel production has been greatly discussed in Brazil. In 2004, these debates led the country to develop new policies and implement a national program for biodiesel use and production (PNPB with the intent to increase the share of renewable energy and foster regional development. In this context, the present study aims to assess the impacts of PNPB on regional development in Tocantins State, northern Brazil. For this purpose, ranges of socio-economic indicators were collected among national and regional stakeholders, as well as specific literature. The preliminary results point out that distribution logistics appears to be a considerable constraint to the success of the PNPB. The concentration of biodiesel industries in the central-west region of the country, and the large distances to deliver biodiesel in the northern Brazil make biodiesel prices non-competitive when compared to fossil diesel. The results also suggest that the PNPB is not succeeding in promoting the integration of family agriculture in the Tocantins state, especially due to the structural difficulty of the agricultural sector, as well as the technical and political shortcomings presented by the mechanism of incentives.

    Introduction: Human papillomavirus (HPV), belonging to the Papovavirida family, is the most prevalent sexually transmitted disease (STD) agent worldwide. In Brazil, it is estimated that there are 3-6 million people infected with HPV. Aim: The aim of this study was to evaluate the knowledge of young male students about penis cancer related to HPV infection. Methods: This exploratory and quantitative study was conducted to analyze answers of 242 male students attending a private college located in Uberaba city, Minas Gerais state, Brazil, during 2015. Results: Most of the 242 participants (88.8%) affirmed having started sexual life very early, the majority (79.3%) were currently married and 69.8% had a single sexual partner. Regardless of their knowledge about HPV virus and its relationship with penis cancer, our data showed a general lack of awareness of the participants. Conclusion: Our results suggest that despite efforts to propagate information about HPV infection and its relation to penis cancer, the level of knowledge of students is low. Because of that, it is important to improve the information spread by media, emphasizing prevention and treatment of HPV infection in men. Creative Commons Attribution License

    Full Text Available This article focuses on the determinants of firm's growth in Brazil. In particular it investigates the individual characteristics of firm that determine its growth; how institutional development affects firm's performance, and how institutional development differently affects small and large firms. We find that, consistently with the learning models, growth is decreasing on age and negatively correlated to size. As expected, firms that belong to an economic group, export and maintain operations abroad grow faster. Growth is negatively correlated to profitability. Furthermore, we observe that shortcomings in institutional development, when measured in terms of corruption, inefficiency of the judicial system and lack of financial development, have a negative impact on firms' growth. This negative impact of corruption and inefficiency of the judicial system is stronger for smaller firms. Large firms benefit the most with financial development. Overall our results indicate that improvement in institutions can be an important mechanism to promote growth. Furthermore, institutional underdevelopment has the perverse effect of promoting concentration.Este artigo foca nos determinantes da taxa de crescimento das firmas no Brasil. Em particular, investigamos as características individuais das empresas que determinam o seu crescimento, como o desenvolvimento institucional afeta a performance da firma e como o desenvolvimento institucional afeta de maneira diversa pequenas e grandes empresas.

    The Global Positioning System (GPS) is widely used by the civil community. Differential GPS (DGPS) was developed to provide better accuracy than autonomous GPS. The DGPS concept is based on the high correlation of errors due to atmospheric effects, satellite clocks and orbits. However, as the baseline grows, its efficiency decreases because the error correlation is reduced. This limitation can be handled by using a reference station network and applying the network DGPS concept (called NDGPS). In this paper, the goal is to present aspects related to the development and application of NDGPS in real time at the São Paulo state network in Brazil. The NDGPS corrections were computed from data received via the Internet using NTRIP (Networked Transport of RTCM via Internet Protocol). Our implementation was based on BNC (BKG Ntrip Client) software. NDGPS provided RMS improvements of up to 59% in horizontal components and 31% in vertical components when compared to DGPS. The availability of the system, the first of this nature in Brazil, was also analyzed within the context of the SP State GNSS Network, located in the southeastern region of Brazil. The results also serve as an indication of the quality of local internet infrastructure for using in geodetic positioning.

    The objective of this article is to contribute to the analysis of the Brazilian public policy related to biodiesel within the context of sustainable development and environmental management. Biofuels have been steadily increasing in popularity on a global scale. Brazil, a country that boasts abundant natural resources and agricultural land, has emerged as a world leader in the production of biofuels. In order to verify biodiesel's potential to contribute to sustainable development, it is necessary to analyze the biofuel in a larger social, environmental, and economic context. The methodology applied to this study included a brief review of the evolution of the concept of sustainable development and instruments of environmental management, which served as a basis to evaluate the policy documents and data relating to the policy's implementation. Although the implementation is still within its initial stage, significant weakness has been found in the policy. One consequence is the domination of soy as a primary material for biodiesel. Other weaknesses identified are related to the Selo (''certification of a socially inclusive fuel'') to promote social inclusion, as well as a lack of support for family-based agriculture to aggregate value to the primary material that they produce.

    The Joint Research Centre of the European Commission (JRC) is developing the prototype of the European Drought Observatory (EDO) for drought forecasting, detection, and monitoring in Europe. EDO is conceived as a web-based information system (http://edo.jrc.ec.europa.eu), integrating information from various sources and disciplines relevant to monitor and detect droughts throughout Europe. The prototype is currently performing the pre-operational production of drought indices using meteorological information, modelled hydrological parameters, and remote sensing data. In particular, the Standardized Precipitation Index (SPI) shows the general precipitation status according to the historical average in the predefined period. SPI in monthly step is calculated for the 1, 3, 6, 9 and 12 months averaging periods. Soil moisture estimations are produced daily by the LISFLOOD hydrological model, along with their anomalies and seven days forecasts. Two satellite remote sensing drought indicators are produced: Normalized Difference Water Index (NDWI) and Fraction of Absorbed Photosynthetic Active Radiation (fAPAR) anomalies. NDWI 10-day composites are obtained daily from Moderate Resolution Imaging Spectroradiometer (MODIS) data, while fAPAR anomalies are calculated from 10-day composites delivered by the European Space Agency (ESA) and estimated from Medium Resolution Imaging Spectrometer Instrument (MERIS) data. All these drought indicators are made available online for visualization and querying by means of a map viewer based on University of Minnesota MapServer and Oracle. The tool generates maps of the different indicators and provides functionalities to browse the maps, query the data, produce graphs, and output the maps in various formats.

It is often argued that personalizing treatment will inevitably improve clinical outcomes for patients and help achieve more effective use of health care resources. Demand is increasing for demonstrable evidence of clinical and cost-effectiveness to support the use of personalized medicine in health care. This paper begins with an overview of the existing challenges in conducting economic evaluations of genetics- and genomics-targeted technologies, as an example of personalized medicine. Our paper illustrates the complexity of the challenges faced by these technologies by highlighting the variations in the issues faced by diagnostic tests for somatic variations, generally referring to genetic variation in a tumor, and germline variations, generally referring to inherited genetic variation in enzymes involved in drug metabolic pathways. These tests are typically aimed at stratifying patient populations into subgroups on the basis of clinical effectiveness (response or safety (avoidance of adverse events. The paper summarizes the data requirements for economic evaluations of genetics and genomics-based technologies while outlining that the main challenges relating to data requirements revolve around the availability and quality of existing data. We conclude by discussing current developments aimed to address the challenges of assessing the cost-effectiveness of genetics and genomics-based technologies, which revolve around two central issues that are

    Full Text Available INTRODUCTION: Among psychiatric disorders schizophrenia is often said to be the condition with the most disputed definition.The Bleulerian and Schneiderian approaches have given rise to diagnostic formulations that have varied with time and place. Controversies over the concept of schizophrenia were examined within European/North American settings in the early 1970s but little has since been reported on the views of psychiatrists in developing countries. In Brazil both concepts are referred to in the literature. A scale was developed to measure adherence to Bleulerian and Schneiderian concepts among psychiatrists working in S. Paulo. METHODOLOGY: A self-reported questionnaire comprising seventeen visual analogue-scale statements related to Bleulerian and Schneiderian definitions of Shizophrenia, plus sociodemographic and training characteristics, was distributed to a non-randomised sample of 150 psychiatrists. The two sub-scales were assessed by psychometric methods for internal consistency, sub-scale structure and test-retest reliability. Items selected according to internal consistency were examined by a two-factor model exploratory factor analysis. Intraclass correlation coefficients described the stability of the scale. RESULTS: Replies were received from 117 psychiatrists (mean age 36 (SD 7.9, 74% of whom were made and 26% female. The Schneiderian scale showed better overall internal consistency than the Bleulerian scale. Intra-class correlation coefficients for test-retest comparisons were between 0.5 and 0.7 for Schneiderian items and 0.2 and 0.7 for Bleulerian items. There was no negative association between Bleulerian and Schneiderian scale scores, suggesting that respondents may hold both concepts. Place of training was significantly associated with the respondent's opinion; disagreement with a Bleulerian standpoint predominated for those trained at the University of S. Paulo. CONCLUSIONS: The less satisfactory reliability for the

    Full Text Available Food is central to human beings and their social life. The growing industrialization of the food system has led to a greater availability of food, along with an increasing risk perception and awareness in consumers. At the same time, there is an increasing resistance from citizens to the dominant model of production and a growing demand for healthy food. As a consequence, an increasing number of social networks have been formed worldwide involving the collaboration between producers and consumers. One of these networks, the Ecovida Agroecology Network, which operates in Southern Brazil, involves farming families, non-governmental organizations, and consumer organizations, together with other social actors. Using a qualitative approach based on participant observation and an analysis of documents, the article examines this network. The theoretical framework used is social innovation, which is commonly recognized as being fundamental in fostering rural development. Results show that Ecovida has instigated innovations that relate to its horizontal and decentralized structure, its participatory certification of organic food, and its dynamic relationship with the markets based on local exchanges and reciprocal relations. Furthermore, such innovation processes have been proven to impact on public sector policies and on the increasing cooperation between the social actors from rural and urban areas.

    A fast paced industrial and port development has occurred at Suape Estuary, Northeast Brazil, but no information about hydrocarbon concentrations in water is available to this area. Considering that, the contamination level of Suape was determined by UV-Fluorescence in terms of dissolved and/or dispersed petroleum hydrocarbons (DDPHs), during wet and dry seasons. DDPHs ranged between 0.05 and 4.59 μg L(-1) Carmópolis oil equivalents and 0.01-1.39 μg L(-1) chrysene equivalents, indicating DDPHs close to a baseline contamination level. Some relatively high concentrations (>1 μg L(-1)) were probably associated with shipyard operations (hull paintings and ship docking), pollutants remobilization by dredging operations, occasional industrial discharges and oil derivatives released by vessels. DDPHs concentrations were lower in the wet season suggesting that the increased dilution rates caused by rainfall dominated upon the wet deposition of atmospheric combustion-derived PAHs process. Results in this study may be used as baseline to further studies in this area. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The present study is part of a project designed to investigate the development of disorders related to the work of orchestra violinists. To describe and analyze the functional disorders of the musculoskeletal systems of violinists from the four orchestras in Belo Horizonte, Brazil. Analyses of musculoskeletal system disorders found in violinists from orchestras in Belo Horizonte, Brazil, were completed using a variety of approaches, including Occupational Therapy, Epidemiology and the Social Science methodologies. Participants sustained musculoskeletal disorders despite their common sense belief that musicians are generally healthier than other professional groups. The struggle for a better financial situation forced study participants to work harder, in a variety of work environments, increasing and diversifying their exposure to risk factors. Protective and preventive measures were scarce and in most cases these were only employed after the onset of musculoskeletal disorders. The use of inadequate strategies and the lack of appropriate options to deal with risk factors contributed to the maintenance of symptoms or the onset of health disorders.

    2012-12-01

    The article contextualizes the emergence of an international policy for the Brazilian Unified Health System as the common agenda of the Pan American Health Organization (PAHO) and the Brazilian Ministry of Health. For this purpose, two contextual axes were explored throughout the work. The first discusses the explicit relationship between the development-cooperation-health triad from an international perspective. The second examines the recent evolution of Brazilian foreign policy, particularly with respect to the role it is playing in South-South cooperation on health matters. The contextual framework that defines Brazilian international cooperation with PAHO is emphasized, above all with regard to the implementation of a specific cooperation agreement. The article concludes that this agreement, within the framework of South-South cooperation, is one of the principal institutional mechanisms established to bring about technical cooperation in health in the current setting.

  16. Small-scale Tourism Development in Brazilian Amazonia: The Creation of a ‘Tourist Bubble’

    Directory of Open Access Journals (Sweden)

    Mirjam A.F. Ros-Tonen

    2009-04-01

    Full Text Available In Brazil, tourism is promoted as a means of generating employment, tax revenues, foreign exchange and investments in infrastructure. The Amazon region is thereby primarily marketed as a ‘green’ destination. One such a destination is the village of Alter do Chão in the municipality of Santarém in the state of Pará, where tourism has expanded rapidly during the past decade. Looking at the main characteristics of tourism in the study area and the actors involved, the authors show that the notion of a ‘tourist bubble’, which was developed for large-scale enclave-like resorts, may apply equally to a small-scale destination. First, it is in the sense of abstracting from historical and cultural contexts in relation to the antecedents of the local population and by commercializing the local Sairé festival as ‘staged authenticity’. Second, a ‘tourist bubble’ is emerging as a result of increasing physical and functional segregation of tourism and residential areas. As far as the local population is concerned, the creation of the ‘bubble’ primarily represents new economic opportunities. However, the introduction of ‘invented traditions’ is also easily adopted because it fits in with the ongoing ethnic reclassification process in Brazil among culturally fragmented populations in search for their ‘roots’ and lost rights. The authors conclude that in order to fully understand the complexity and dynamics of cultural and economic transformations following tourism development, it is necessary to also look beyond the ‘tourist bubble’.Resumen: El desarrollo turístico de pequeña escala en la Amazonía brasileña: la creación de una ‘burbuja turística’En Brasil, los gobiernos en todos niveles están promoviendo el turismo para generar empleo, impuestos, divisas e inversiones en infraestructura.

    Grande do Sul. Many were relatively small producers who were attracted to the Alto Parana region of Paraguay near the Brazilian border by its geographic proximity, extensive availability of land at low prices, and favorable credit and tax policies. Many small proprietors from Brazil were able to buy extensive tracts in Paraguay and to develop an economy based on cultivation of export crops on small and medium sized holdings. A serious and efficient plan for financial aid, together with technical assistance and intensive training programs, could have placed Paraguayan cultivators in a position similar to that of the Brazilians. Paraguayan colonists in the frontier areas could then have progressed rapidly beyond their current state of subsistence or semisubsistence agriculture to the kind of entrepreneurial agriculture practiced by the Brazilians.

    2015-01-01

    In this article, we present the Brazilian Portuguese Lexicon, a new word-based corpus for psycholinguistic and computational linguistic research in Brazilian Portuguese. We describe the corpus development, the specific characteristics on the internet site and database for user access. We also perform distributional analyses of the corpus and comparisons to other current databases. Our main objective was to provide a large, reliable, and useful word-based corpus with a dynamic, easy-to-use, and intuitive interface with free internet access for word and word-criteria searches. We used the Núcleo Interinstitucional de Linguística Computacional's corpus as the basic data source and developed the Brazilian Portuguese Lexicon by deriving and adding metalinguistic and psycholinguistic information about Brazilian Portuguese words. We obtained a final corpus with more than 30 million word tokens, 215 thousand word types and 25 categories of information about each word. This corpus was made available on the internet via a free-access site with two search engines: a simple search and a complex search. The simple engine basically searches for a list of words, while the complex engine accepts all types of criteria in the corpus categories. The output result presents all entries found in the corpus with the criteria specified in the input search and can be downloaded as a.csv file. We created a module in the results that delivers basic statistics about each search. The Brazilian Portuguese Lexicon also provides a pseudoword engine and specific tools for linguistic and statistical analysis. Therefore, the Brazilian Portuguese Lexicon is a convenient instrument for stimulus search, selection, control, and manipulation in psycholinguistic experiments, as also it is a powerful database for computational linguistics research and language modeling related to lexicon distribution, functioning, and behavior.

  4. Development and validation of the Brazilian version of the Attitudes to Aging Questionnaire (AAQ: An example of merging classical psychometric theory and the Rasch measurement model

    Directory of Open Access Journals (Sweden)

    Trentini Clarissa M

    2008-01-01

    Full Text Available Abstract Background Aging has determined a demographic shift in the world, which is considered a major societal achievement, and a challenge. Aging is primarily a subjective experience, shaped by factors such as gender and culture. There is a lack of instruments to assess attitudes to aging adequately. In addition, there is no instrument developed or validated in developing region contexts, so that the particularities of ageing in these areas are not included in the measures available. This paper aims to develop and validate a reliable attitude to aging instrument by combining classical psychometric approach and Rasch analysis. Methods Pilot study and field trial are described in details. Statistical analysis included classic psychometric theory (EFA and CFA and Rasch measurement model. The latter was applied to examine unidimensionality, response scale and item fit. Results Sample was composed of 424 Brazilian old adults, which was compared to an international sample (n = 5238. The final instrument shows excellent psychometric performance (discriminant validity, confirmatory factor analysis and Rasch fit statistics. Rasch analysis indicated that modifications in the response scale and item deletions improved the initial solution derived from the classic approach. Conclusion The combination of classic and modern psychometric theories in a complementary way is fruitful for development and validation of instruments. The construction of a reliable Brazilian Attitudes to Aging Questionnaire is important for assessing cultural specificities of aging in a transcultural perspective and can be applied in international cross-cultural investigations running less risk of cultural bias.

    This study aimed to identify the prevalence and correlates of meeting the current physical activity for health (PAfH) guidelines, proposed by the World Health Organization in 2010, in community-dwelling older women from Brazil. A cross-sectional study was performed with 1806 women (aged 60.0-92.7 years) who were randomly selected from eighteen care centers. The short version of the International Physical Activity Questionnaire was used to determine the weekly time spent in physical activities, and this variable was categorized into three categories (0<150min/wk; 1: 150-299.9min/wk; 2: ≥300min/wk). Age, race/ethnicity, economic class, education level, occupational and marital status, body mass index and blood pressure status, medical conditions, use of medications, and self-rated health status were the potential correlates. The ordinal logistic regression was used as a measure of association. From the total group of participants, 49.9% followed the current recommendations related to basic health benefits (150-299min/wk), and 35.9% met the guidelines for additional health effects (300 or more min/wk). Women with secondary complete education (OR=1.43, 95% confidence interval [CI]: 1.17-1.74), positive self-rated health (OR=5.25, 95% CI: 2.10-13.09), and high blood pressure (OR=1.33, 95% CI: 1.09-1.62) were more likely to meet the current PAfH guidelines than their peers with primary incomplete education, negative self-rated health, and normal blood pressure. Increasing age was inversely associated with meeting the PAfH guidelines (odds ranging: 0.77-0.48). These results highlighted the elderly population subgroups, in a developing country, that needspecific guidelinesfor inclusion inhealth programs andmotivation toparticipate in physical activities.

    2017-01-01

    The minimally invasive surgery for gastric cancer in Brazil has begun about two years after the first laparoscopic gastrectomy (LG) performed by Kitano in Japan, in 1991. Although the report of first surgeries shows the year of 1993, there was no dissemination of the technique until the years 2010. At that time with the improvement of optical devices, laparoscopic instruments and with the publications coming from Asia, several Brazilian surgeons felt encouraged to go to Korea and Japan to learn the standardization of the LG. After that there was a significant increase in that type of surgery, especially after the IRCAD opened a branch in Brazil. The growing interest for the subject led some services to begin their own experience with the LG and, since the beginning, the results were similar with those found in the open surgery. Nevertheless, there were some differences with the papers published initially in Japan and Korea. In those countries, the surgeries were laparoscopic assisted, meaning that, in the majority of cases, the anastomoses were done through a mini-incision in the end of the procedure. In Brazil since the beginning it was performed completely through laparoscopic approach due to the skills acquired by Brazilian surgeons in bariatric surgeries. Another difference was the stage. While in the east the majority of cases were done in T1 patients, in Brazil, probably due to the lack of early cases, the surgeries were done also in advanced cases. The initial experience of Zilberstein et al. revealed low rates of morbidity without mortality. Comparing laparoscopic and open surgery, the group from Barretos/IRCAD showed shorter surgical time (216×255 minutes), earlier oral or enteral feeding and earlier hospital discharge, with a smaller number of harvested lymph nodes (28 in laparoscopic against 33 in open surgery). There was no significant difference regarding morbidity, mortality and reoperation rate. In the first efforts to publish a multicentric study

    Full Text Available Cutaneous malignant melanoma is the most lethal form of skin cancer and an increasingly common disease worldwide. It remains one of the most treatment-refractory malignancies. The current treatment options for patients with metastatic melanoma are limited and in most cases non-curative. This review focuses on conventional chemotherapeutic drugs for melanoma treatment, by a single or combinational agent approach, but also summarizes some potential novel phytoagents discovered from dietary vegetables or traditional herbal medicines as alternative options or future medicine for melanoma prevention. We explore the mode of actions of these natural phytoagents against metastatic melanoma.

    The genus Solanum (family Solanaceae) includes more than 1400 species and has buzz-pollinated flowers with poricidal anthers. The present study aimed to describe the distribution, breeding system and pollination mechanism of Solanum melissarum, a species endemic to Brazil. The study of breeding system was conducted in an urban forest fragment in Jataí, GO. Distribution data were gathered from floristic surveys and digital plant databases. The floral morphology and the pollination mechanism were studied on through field observations and preserved flowers. The breeding system was determined through hand pollination treatments. The species has a distribution only in the Brazilian Atlantic forest coastal, and this study provides the first records of S. melissarum for the state of Goiás. The pendulous flowers have poricidal anthers close to the stigma, with membranous thecae joined by a connective bearing osmophores that attract males of Euglossa cordata bees. As they collect fragrances, the bees press the thecae and pollen is released through a bellows mechanism. Based on the hand-pollination treatments, this species is self-incompatible. Isolated forest fragments may not include enough pollinators to ensure the pollination of plants with specialized systems. However, they are essential for the conservation of species with interesting phytogeographic patterns, such as the vicariance observed in S. melissarum, and for the conservation of regional diversity.

    2009-12-01

    The development of peptides as drugs is attracting increasing attention from the pharmaceutical industry. This interest is at least partially a consequence of the widespread acceptance of therapeutic proteins by physicians and patients, and because of improvements to problems such as a short half-life and delivery issues. The markets for peptide-based compounds can be substantial, with six peptide drugs attaining global sales of more than US $750 million in 2008. To track trends in the clinical development and marketing approval of peptides, Tufts Center for the Study of Drug Development and Ferring Research Institute compiled publically available data for peptides that entered clinical trials sponsored by commercial firms, with a focus on peptide therapeutics, but also including peptide vaccines and diagnostics. The results provide an historical overview of the development of peptide therapeutics, and may inform strategic planning in this area.

Evidence shows telehealth has been used in essentially all countries of the world, but is embedded in few. Uses and needs of telehealth vary between the developed and developing world; the latter struggles with both communicable diseases and noncommunicable diseases, and with very few resources. Common clinical applications include teleconsultation, telecardiology (transmission of ECGs, teleradiology, and teledermatology. Many telehealth projects exist throughout Latin America and the Caribbean, Asia, and Africa, but there is little published evidence and only isolated examples of sustained programs, although several sustained humanitarian networks exist. Application of mobile solutions (m-health is on the rise in many developing countries. Telehealth is still not integrated into existing health care systems globally. Reasons vary: lack of proven large-scale operations, poor evidence base, inadequate implementation, lack of attention to the “soft side” of implementation (readiness, change management, and many others. For the developing world, reasons can be more pragmatic, including limited resources, unreliable power, poor connectivity, and high cost for the poverty stricken – those most in need. Telehealth is poised to improve health and health care in the developing world, driven by both altruistic and profit motives. But to have the desired effect, telehealth must address very specific and evidence-based health “needs” of each facility, region, or country; the shortage of health workers and specialist services; and the required skills upgrading and training

    2008-03-01

    Even 125 year after the discovery of Mycobacterium tuberculosis as the aetiological agent of tuberculosis by Robert Koch, tuberculosis is still a global health emergency according to WHO. The high infection rate with M. tuberculosis that persists in the human host until a weakened host immune system allows a reactivation and complicated and expensive antituberculous chemotherapy urgently demand the development of new vaccines. Increasing numbers of multidrug-resistant tuberculosis, especially in the successor states of the former Soviet Union and China, further complicate an efficient tuberculosis control. For decades, there was no new release of an antituberculous drug to efficiently fight tuberculosis. Hence, also drug development has to keep up with the development of resistance by the pathogen. The following review describes the immune response to M. tuberculosis infection and the deduction of strategies for novel vaccines. Thanks to international financial support, several new vaccine candidates are already in the pipeline and close to clinical testing phases.

    Mucosal vaccination has several advantages compared with that of injection-type vaccination. Secretory IgA(SIgA) produced at mucosal surface plays a key role for inactivation of toxins and inhibition of pathogen invasion. Although oral or nasal vaccination with attenuated live microorganisms have been shown to be effective in the induction of protective immunity, these types of vaccine have the ability to infect transiently to the host. For the development of safe and effective mucosal vaccine, an obvious strategy is the preparation of inactivated subunit-type mucosal vaccine. Here we introduce our frontier technology for the development of rice-based oral vaccines, as a new generation of mucosal vaccine. Further, we also discuss recent progress in the development of other types of mucosal vaccine and adjuvant.

The resulting hyperammonemia causes severe brain injury unless aggressive steps are taken to reduce the accumulation of ammonia, which is thought to be the most toxic metabolite. This review describes the current state of chronic management of urea cycle disorders, focusing on new and emerging therapies. Management strategies include the mainstay of treatment, namely dietary protein restriction and supplementation with l-arginine or l-citrulline. Several currently approved medications utilize and enhance alternative pathways of waste nitrogen excretion (sodium benzoate, sodium phenylacetate, sodium phenylbutyrate in several formulations, and glycerol phenylbutyrate, working through conjugation of the drug to either glycine (in the case of benzoate or glutamine, the products of which are excreted in the urine. Carglumic acid activates the first committed step of conversion of ammonia to urea, carbamoylphosphate synthetase, and thus effectively treats defective synthesis of the endogenous activator, N-acetylglutamate, whether due to genetic defects or biochemical inhibition of the N-acetylglutamate synthase enzyme. Approaches to neuroprotection during episodes of hyperammonemia are discussed, including the use of controlled hypothermia (brain cooling, as well as proposed, but as yet untested, pharmacologic therapies. Finally, cell-based therapies, including liver transplantation, infusion of fresh or cryopreserved hepatocytes, use of stem cells, and new approaches to gene

    Full Text Available This paper presents fat mass centile charts for Brazilian youth and investigates the roles of socioeconomic status and physical fitness (PF on fat mass (FM development. Two northeast Brazilian samples were used: a cross-sectional sample of 3659 (1921 girls aged 8 to 16 years and a mixed-longitudinal series of cohorts (8–10, 10–12, 12–14, 14–16 years with 250 boys and 250 girls. A measure of somatic maturity was used as a marker of biological maturation; PF comprised agility, explosive and static strength, and aerobic capacity. Socioeconomic status was based on school attended; public or private. Slaughter’s anthropometric equations were used to estimate FM. Percentile charts was constructed using the LMS method. HLM (Hierarchical Linear Model 7 software modeled FM changes, identifying inter-individual differences and their covariates. Girls and boys had different FM percentile values at each age; FM increased nonlinearly in both girls and boys. Higher PF levels reduced FM changes across time in both sexes. Sex-specific non-linear FM references were provided representing important tools for nutritionists, pediatriciann and educators. Physical fitness levels were found to act as a protective factor in FM increases. As such, we emphasize PF importance as a putative health marker and highlight the need for its systematic development across the school years.

    Behavioral medicine in China has developed quickly in the last three decades. We briefly summarized the history, the main scope and achievements, and the future development of behavioral medicine in China. We did a literature search and discussed with senior scholars in behavioral medicine in China. The concept and main scope of behavioral medicine in China have been developed largely in accordance with the international perspective. Research in behavioral medicine in China significantly contributed to the better understanding of the relationship between various health behavioral factors and psychosomatic disorders and possible mechanisms of this relationship. The following aspects will be the main areas to be further developed in behavioral medicine in China: (1) Basic theories of behavioral medicine and theoretical mechanisms of higher nervous activities in human behavior regulation. (2) Etiology, pathogenesis, and mechanisms of common diseases that are closely related to human lifestyle behaviors. (3) Assessment criteria for unhealthy and disease-related behaviors. (4) Behavioral therapy of psychosomatic disorders, and rehabilitation technologies of disability. (5) Application of major findings from research of behavioral medical science in clinical practice and in health promotion of the whole society. Behavioral medicine in China, as a multidisciplinary subject, plays a relevant role in preventing behavior-related psychosomatic diseases and in promoting health of the public.

  7. New and Traditional Multilateral Development Banks: Current and Potential Cooperation

    Full Text Available Most experts on multilateral development banks (MDBs mention the possibility of large-scale co-financing in their forecasts concerning their future operations. However, interaction between MDBs and other actors, including co-financing, is rarely considered as a research problem for analytical and scientific papers. Yet this type of cooperation is one of the most important factors of effectiveness for the entire system of MDB financing. Thus, working in partnership with governmental institutions (development assistance agencies, export credit agencies, etc., MDBs help attract additional financial resources and expertise in the countries where they are active. Working on state, regional and global levels, multilateral banks cooperate not only with governmental institutions, but also with private sector and civil society representatives. Such cooperation benefits both parties. In addition to mobilizing additional financial resources, it improves project preparation and implementation, taking into account national peculiarities, while partner institutions get a chance to use their experience and expertise. Given the recent establishment of the New Development Bank (NDB and Asian Infrastructure Investment Bank (AIIB, they are unlikely to achieve their main goal of narrowing the infrastructure financing deficit in developing countries without active cooperation with other institutions. This article discusses the results and examines the prospects of the NDB and AIIB cooperating with traditional MDBs. It also focuses on the new banks’ engagement with other financial institutions, including commercial banks and national development banks. The author analyzes interbank memorandums and agreements as a formal basis for cooperation between various institutions, and examines in detail the examples of co-financing infrastructure projects by the new and traditional MDBs, as well as new multilateral cooperation mechanisms established by development banks.

    Syphilis is a multistage disease caused by the invasive spirochete Treponema pallidum subsp. pallidum. Despite inexpensive and effective antibiotic therapy, syphilis remains a prevalent disease in developing countries and has re-emerged as a public health threat in developed nations. In addition to the medical burden imparted by infectious syphilis, congenital syphilis is considered the most significant infectious disease affecting fetuses and newborns worldwide, and individuals afflicted with syphilis have an enhanced risk for HIV transmission and acquisition. The global disease burden of syphilis and failure of decades of public health efforts to stem the incidence of disease highlight the need for an effective syphilis vaccine. Although challenges associated with T. pallidum research have impeded understanding of this pathogen, the existence of a relevant animal model has enabled insight into the correlates of disease protection. Complete protection against infection has been achieved in the animal model using an extended immunization regimen of γ-irradiated T. pallidum, demonstrating the importance of treponemal surface components in generation of protective immunity and the feasibility of syphilis vaccine development. Syphilis is a prime candidate for development of a successful vaccine due to the (1) research community's accumulated knowledge of immune correlates of protection; (2) existence of a relevant animal model that enables effective pre-clinical analyses; (3) universal penicillin susceptibility of T. pallidum which enhances the attractiveness of clinical vaccine trials; and (4) significant public health benefit a vaccine would have on reduction of infectious/congenital syphilis and HIV rates. Critical personnel, research and market gaps need to be addressed before the goal of a syphilis vaccine can be realized, including recruitment of additional researchers to the T. pallidum research field with a proportional increase in research funding

    Full Text Available The global meat market and primarily the chicken meat market represents a very dynamically developing area. The objective of the present article is the analysis of the chicken meat market in the world in order to identify the basic development trends associated with the development of production of and trade in chicken meat, and also in order to identify the individual entities controlling the global chicken meat market. In methodological terms, the article analyzes the development of production of, consumption of and trade (export and import in chicken meat in the years 1961–2009. The main sources of data necessary for the processing of the individual analyses are the FAOSTAT and UN COMTRADE databases. The results of the conducted analysis show the following findings. World production of poultry meat increased from 7.5 million tons to more than 86 million tons. The global market reacted in a flexible manner, in which there was an increase in volumes of executed trade from 271 thousand tons/year in the year 1961 to more than 10.7 million tons/year in the year 2010. Further, the value of world trade in chicken meat within the analyzed period increased from approximately USD 169 million to approximately USD 16 billion. If we analyze the global chicken meat market, it may be stated that it is very concentrated. The analysis of the global market further shows that Brazil, the USA and China represent, in terms of global production, consumption and trade, the main driving force on the chicken meat market. These three countries have a share in global production of approximately 46%, their share in global consumption ranges at a level of over 40%. The share of these countries in global export ranges at a level exceeding 50%.

    2017-01-01

    Epigenetics has drawn much attention as a mechanism of transcriptional regulation involving modifications to genomic DNA and histone, without changes to nucleotide sequences. Epigenetics is related to various biological phenomena. We defined one of these phenomena as "epigenetic toxicity", in which chemicals affect epigenetic regulation and result in undesirable effects on living organisms. We then detailed the importance of epigenetics and the need for intensive research. Epigenetics is a mechanism that might explain the long-lasting effects of chemicals in an organism, and the formation of a predisposition to various diseases. Recent significant technological advancement in the study of epigenetics could break through the barrier of the mysterious black box of epigenetic toxicity. However, at present it is difficult to say whether the epigenetic point of view is being fully utilized in the evaluation of chemical safety. In this review, we will first summarize the epigenetic toxicity research field, with examples of epigenetic toxicities and technologies for epigenetic analysis. Following that, we will point out some challenges in which an epigenetic viewpoint may be essential for the evaluation of chemical safety, and we will show some current approaches. We hope this review will trigger a discussion about epigenetic toxicity that will lead to encouraging research advancements.

    Kashikar-Zuck, Susmita; Ting, Tracy V.

    2015-01-01

    Juvenile-onset fibromyalgia (JFM) is a poorly understood chronic pain condition most commonly affecting adolescent girls. The condition is characterized by widespread musculoskeletal pain and other associated symptoms, including fatigue, nonrestorative sleep, headaches, irritable bowel symptoms, dysautonomia and mood disorders such as anxiety and/or depression. In the past few years, there has been a greater focus on understanding JFM in adolescents. Research studies have provided insight into the clinical characteristics of this condition and its effect on both short-term and long-term psychosocial and physical functioning. The importance of early and effective intervention is being recognized, as research has shown that symptoms of JFM tend to persist and do not resolve over time as was previously believed. Efforts to improve treatments for JFM are underway, and new evidence strongly points to the potential benefits of cognitive–behavioural therapy on improving mood and daily functioning. Research into pharmacotherapy and other nonpharmacological options is in progress. Advancements in the understanding of adult fibromyalgia have paved the way for future studies on diagnosis, assessment and management of JFM. This Review focuses on our current knowledge of the condition, provides an update of the latest research advances, and highlights areas for further study. PMID:24275966

    Dengue is a significant global health problem. Even though a vaccine against dengue is now available, which is a notable achievement, its long-term protective efficacy against each of the 4 dengue virus serotypes remains to be definitively determined. Consequently, drugs directed at the viral targets or critical host mechanisms that can be used safely as prophylaxis or treatment to effectively ameliorate disease or reduce disease severity and fatalities are still needed to reduce the burden of dengue. This review will provide a brief account of the status of therapeutics research and development for dengue. © The Author 2016.

    Amanna, Ian J.; Slifka, Mark K.

    2014-01-01

    West Nile virus (WNV) is a mosquito-borne flavivirus that has become endemic in the United States. From 1999-2012, there have been 37,088 reported cases of WNV and 1,549 deaths, resulting in a 4.2% case-fatality rate. Despite development of effective WNV vaccines for horses, there is no vaccine to prevent human WNV infection. Several vaccines have been tested in preclinical studies and to date there have been 8 clinical trials, with promising results in terms of safety and induction of antiviral immunity. Although mass vaccination is unlikely to be cost-effective, implementation of a targeted vaccine program may be feasible if a safe and effective vaccine can be brought to market. Further evaluation of new and advanced vaccine candidates is strongly encouraged. PMID:24689659

    2010-09-01

    Brain-computer interfaces (BCIs) have been developed over the past decade to restore communication to persons with severe paralysis. In the most severe cases of paralysis, known as locked-in syndrome, patients retain cognition and sensation, but are capable of only slight voluntary eye movements. For these patients, no standard communication method is available, although some can use BCIs to communicate by selecting letters or words on a computer. Recent research has sought to improve on existing techniques by using BCIs to create a direct prediction of speech utterances rather than to simply control a spelling device. Such methods are the first steps towards speech prostheses as they are intended to entirely replace the vocal apparatus of paralyzed users. This article outlines many well known methods for restoration of communication by BCI and illustrates the difference between spelling devices and direct speech prediction or speech prosthesis.

In particular, a speculative forecasting scenario designed in the end of 2004, that properly predicted the world stock market increases in 2007, is updated by setting some more precise constraints on the time of duration of the present long-term equity market bullish phase. A termination of this phase is evaluated to occur in around November 2009. In particular, on the way towards this dead-line, a Spring-Summer 2008 increase is expected. On the precious metals market a forthcoming critical time signal is detected at the turn of March/April 2008 which marks a tendency for at least a serious correction to begin.

  11. Prenatal screening: current practice, new developments, ethical challenges.

    Prenatal screening pathways, as nowadays offered in most Western countries consist of similar tests. First, a risk-assessment test for major aneuploides is offered to pregnant women. In case of an increased risk, invasive diagnostic tests, entailing a miscarriage risk, are offered. For decades, only conventional karyotyping was used for final diagnosis. Moreover, several foetal ultrasound scans are offered to detect major congenital anomalies, but the same scans also provide relevant information for optimal support of the pregnancy and the delivery. Recent developments in prenatal screening include the application of microarrays that allow for identifying a much broader range of abnomalities than karyotyping, and non-invasive prenatal testing (NIPT) that enables reducing the number of invasive tests for aneuploidies considerably. In the future, broad NIPT may become possible and affordable. This article will briefly address the ethical issues raised by these technological developments. First, a safe NIPT may lead to routinisation and as such challenge the central issue of informed consent and the aim of prenatal screening: to offer opportunity for autonomous reproductive choice. Widening the scope of prenatal screening also raises the question to what extent 'reproductive autonomy' is meant to expand. Finally, if the same test is used for two different aims, namely detection of foetal anomalies and pregnancy-related problems, non-directive counselling can no longer be taken as a standard. Our broad outline of the ethical issues is meant as an introduction into the more detailed ethical discussions about prenatal screening in the other articles of this special issue. © 2014 John Wiley & Sons Ltd.

    Okeke, P. N.

    Astronomy is important to developing African countries. In this paper, a brief review of the situation of astronomical research in Africa before 1991 is given. During that period only South Africa and Egypt were carrying out observational research in astronomy. In other African countries astronomy research was in its infancy, except the University of Nigeria Space Research Centre (UNNSRC) in theoretical areas. A summary of the important recommendations for Africa at the United Nations/ European Space Agency (UN/ESA) series of workshops on basic space science were itemized to help identify those which have now been accomplished. Additionally, UNNSRC has now embarked on further observational programmes through the establishment of strong collaborative ventures with two observatories in South Africa, the Hartesbeesthoek Radio Astronomical Observatory (Hart RAO) and the South African Astronomical Observatory (SAAO). UNNSRC has also made permanent arrangements with HartRAO, SAAO, and the Jodrell Bank for collaborations in data analysis. A new interest in astronomy appears to have awakened in Nigeria with three more universities joining this area of basic space science. It is recommended that the time has come for all African countries to contribute towards a common facility such as the Southern African Large Telescope (SALT). The efforts of UN/ESA which resulted in tremendous achievements are commended.

    2005-01-01

    The book explores what can be learned about the Sun and interplanetary space using present-day and future radio observations and techniques. The emphasis is on interpretation of radio data with high spatial and spectral resolution, motivated by the planned construction of a new, powerful, solar-dedicated radio array called the Frequency Agile Solar Radiotelescope (FASR). The book is unique in exploring a broad frequency range, which corresponds to heights ranging from the low solar atmosphere out to the Earth. The book contains a thorough review of the entire field of solar and Space Weather radio research; gives background information suitable for advanced undergraduates, graduates, and researchers in solar and Space Weather research and related fields; and looks at what new results may be expected in the next two decades with FASR and other new instruments now under development. The individual chapters are written by international experts in each topic, and although each chapter may be read as a stand-alone...

  15. Curative treatment of oesophageal carcinoma: current options and future developments

    2011-05-01

    Full Text Available Abstract Since the 1980s major advances in surgery, radiotherapy and chemotherapy have established multimodal approaches as curative treatment options for oesophageal cancer. In addition the introduction of functional imaging modalities such as PET-CT created new opportunities for a more adequate patient selection and therapy response assessment. The majority of oesophageal carcinomas are represented by two histologies: squamous cell carcinoma and adenocarcinoma. In recent years an epidemiological shift towards the latter was observed. From a surgical point of view, adenocarcinomas, which are usually located in the distal third of the oesophagus, may be treated with a transhiatal resection, whereas squamous cell carcinomas, which are typically found in the middle and the upper third, require a transthoracic approach. Since overall survival after surgery alone is poor, multimodality approaches have been developed. At least for patients with locally advanced tumors, surgery alone can no longer be advocated as routine treatment. Nowadays, scientific interest is focused on tumor response to induction radiochemotherapy. A neoadjuvant approach includes the early and accurate assessment of clinical response, optimally performed by repeated PET-CT imaging and endoscopic ultrasound, which may permit early adaption of the therapeutic concept. Patients with SCC that show clinical response by PET CT are considered to have a better prognosis, regardless of whether surgery will be performed or not. In non-responding patients salvage surgery improves survival, especially if complete resection is achieved.

  16. Overview of robotic colorectal surgery: Current and future practical developments

    2016-01-01

    Minimal access surgery has revolutionised colorectal surgery by offering reduced morbidity and mortality over open surgery, while maintaining oncological and functional outcomes with the disadvantage of additional practical challenges. Robotic surgery aids the surgeon in overcoming these challenges. Uptake of robotic assistance has been relatively slow, mainly because of the high initial and ongoing costs of equipment but also because of limited evidence of improved patient outcomes. Advances in robotic colorectal surgery will aim to widen the scope of minimal access surgery to allow larger and more complex surgery through smaller access and natural orifices and also to make the technology more economical, allowing wider dispersal and uptake of robotic technology. Advances in robotic endoscopy will yield self-advancing endoscopes and a widening role for capsule endoscopy including the development of motile and steerable capsules able to deliver localised drug therapy and insufflation as well as being recharged from an extracorporeal power source to allow great longevity. Ultimately robotic technology may advance to the point where many conventional surgical interventions are no longer required. With respect to nanotechnology, surgery may eventually become obsolete.

  17. Invasive FFR — Current Applications and New Developments

    Full Text Available Myocardial ischemia caused by coronary atherosclerosis is the main cause of cardiovascular mortality, which is the first cause of death in developed countries. Inducible myocardial ischemia is a negative prognostic factor for coronary artery disease patients, and it represents a major risk stratification marker for predicting mortality. The evolution of these patients depends largely on the extension of the ischemic myocardial mass and the severity of the inducible ischemia. Most patients do not show angiographically significant coronary stenosis. Therefore, such patients do not undergo coronary revascularization therapies, even though they present functional stenoses that trigger myocardial ischemia under stress conditions, which subsequently lead to a high risk for major adverse cardiovascular events. We performed a review that aims to pinpoint invasive techniques used for evaluating the functional impact of a coronary lesion that is considered non-significant upon angiographic examination, but which triggers episodes of myocardial ischemia under stress conditions, and to describe the functional markers that show the highest specificity for predicting ischemic risk, in order to recommend invasive coronary revascularization.

    Full Text Available Through the many documents regularly emitted by those dedicated to this activity, it is comparatively easy to describe factual developments in the field of open and distance education in different places in the world. However, it is much more difficult to produce judgements of value about their quality. Quality is a subjective rather than an absolute concept and may be examined from different analytical perspectives: consumers' satisfaction level, intrinsic value of scientific and technical content of learning materials, soundness of learning strategies, efficiency of organisation and procedures, adequate use of advanced technologies, reliability of student support mechanisms, etc.These parameters should be put into the context of specific objectives, nature of target populations and availability of different kinds of resources. In a specific geographic, social, economic and cultural situation a given set of solutions might be judged as adequate and deserving the qualification of "good practice," while in a different context it could be considered of rather poor quality.The selection of examples in this article is the sole responsibility of the authors: neither should the chosen cases be considered as clearly better than any other one, nor missing cases be interpreted as lack of appreciation or a negative judgement.Finally, the authors are aware of the risks of interpreting trends and trying to extrapolate them into the near future: readers should use their own judgement in accepting (or forcefully rejecting these projections.

    Full Text Available Background: Immigrants face many challenges when settling in a foreign country, numerous factors influence this immigrant experience including the resources they bring with them and those they find in the host society. The literature has indicated that a significant number of individuals migrate in search of a better quality of life. In this context, the objective of the study was to analyze the quality of life and health of Brazilian immigrants living in Portugal, using the "Medical Outcomes Study: 36-Item Short Form Survey" (SF-36. Methods and Results: A cross-sectional study with a quantitative approach developed under the project titled: Health status and quality of life of Brazilian immigrants in Portugal conducted in the first half of 2016, with 682 Brazilian immigrant women over 18 living in Portugal. This study adopted as reference SF-36, a generic instrument for the evaluation of Quality of Life. It can be affirmed that the quality of life and health of Brazilian immigrants living in Portugal is good, since all dimensions presented values above 50%. It was evidenced that Brazilian immigrants who live alone have lower levels of quality of life and health than those who live with someone and, that Brazilian immigrants who are unemployed, have low levels of quality of life and health compared to those who are in another employment situation, and Brazilian immigrants entering the labor market with a workload of more than 40 hours per week present similar levels of quality of life and health compared to those who work fewer hours. Conclusion: In general, one can affirm that the quality of life and health of Brazilian immigrants living in Portugal is good, but due to the particularities of the migration process in the current political and international context, a systematic monitoring of living conditions and health of this population is necessary.

  20. Interleukin-6 and prostate cancer: Current developments and unsolved questions.

    Science.gov (United States)

    Culig, Zoran; Puhr, Martin

    2017-03-16

    Interleukin (IL)-6 is a pro-inflammatory cytokine that is expressed in prostate tumors and in the stromal tumor micro-enviroment. It is known to regulate proliferation, apoptosis, angiogenesis, and differentiation. The signaling pathway of Janus kinase and signal transducer and activator of transcription (STAT)3, which is activated by IL-6, is in the focus of scientific investigations for improved treatment approaches. Different effects of IL-6 and/or STAT3 on tumor cell growth have been observed in human and murine prostate cancer (PCa) models. Experimental therapies have been proposed in order to block the IL-6/STAT3 signaling pathway. In this context, the anti-IL-6 antibody siltuximab (CNTO 328) has been demonstrated to inhibit growth of prostate tumors in vitro and in vivo and delays progression towards castration resistance. However, clinically, the anti-IL-6 antibody was not successful as a monotherapy in phase II studies in patients with metastatic PCa. IL-6 is implicated in regulation of cellular stemness by increasing phosphorylation of STAT3. The cytokine has also a role in development of resistance to the non-steroidal anti-androgen enzalutamide. Endogenous inhibitors of IL-6 are suppressors of cytokine signaling and protein inhibitors of activated STAT. Although they inhibit signal transduction through STAT3, they may also exhibit anti-apoptotic effects. On the basis of complexity of IL-6 action in PCa, an individualized approach is needed to identify patients who will benefit from anti-IL-6 therapy in combination with standard treatments.

    Bacterial adhesion and subsequent biofilm formation on material surfaces represent a serious problem in society from both an economical and health perspective. Surface coating approaches to prevent bacterial adhesion and biofilm formation are of increased importance due to the increasing prevalence of antibiotic resistant bacterial strains. Effective antimicrobial surface coatings can be based on an anti-adhesive principle that prevents bacteria to adhere, or on bactericidal strategies, killing organisms either before or after contact is made with the surface. Many strategies, however, implement a multifunctional approach that incorporates both of these mechanisms. For anti-adhesive strategies, the use of polymer chains, or hydrogels is preferred, although recently a new class of super-hydrophobic surfaces has been described which demonstrate improved anti-adhesive activity. In addition, bacterial killing can be achieved using antimicrobial peptides, antibiotics, chitosan or enzymes directly bound, tethered through spacer-molecules or encased in biodegradable matrices, nanoparticles and quaternary ammonium compounds. Notwithstanding the ubiquitous nature of the problem of microbial colonization of material surfaces, this review focuses on the recent developments in antimicrobial surface coatings with respect to biomaterial implants and devices. In this biomedical arena, to rank the different coating strategies in order of increasing efficacy is impossible, since this depends on the clinical application aimed for and whether expectations are short- or long term. Considering that the era of antibiotics to control infectious biofilms will eventually come to an end, the future for biofilm control on biomaterial implants and devices is likely with surface-associated modifications that are non-antibiotic related.

    The coastal area concentrates many uses that require integrated management based on diagnostic and predictive tools to understand and anticipate the future of pollution from land or sea, and learn more about natural hazards at sea or activity on the coast. The realistic modelling of coastal hydrodynamics needs to take into account various processes which interact, including tides, surges, and sea state (Wolf [2008]). These processes act at different spatial scales. Unstructured-grid models have shown the ability to satisfy these needs, given that a good mesh resolution criterion is used. We worked on adding a sea state forcing in a hydrodynamic circulation model. The sea state model is the unstructured version of WAVEWATCH III c (Tolman [2008]) (which version is developed at IFREMER, Brest (Ardhuin et al. [2010]) ), and the hydrodynamic model is the 2D barotropic module of the unstructured-grid finite element model T-UGOm (Le Bars et al. [2010]). We chose to use the radiation stress approach (Longuet-Higgins and Stewart [1964]) to represent the effect of surface waves (wind waves and swell) in the barotropic model, as previously done by Mastenbroek et al. [1993]and others. We present here some validation of the model against academic cases : a 2D plane beach (Haas and Warner [2009]) and a simple bathymetric step with analytic solution for waves (Ardhuin et al. [2008]). In a second part we present realistic application in the Ushant Sea during extreme event. References Ardhuin, F., N. Rascle, and K.

    Full Text Available Competences, interdisciplinarity and contextualization became part of the discourse from the majority of educators, mainly after the issue of the Curricular Directives for High School Teaching (DCNEM and the National Curricular Parameters (PCN and PCN+ by the Brazilian Ministry of Education. Nevertheless, this does not imply that their practices are aligned with the proposals embodied in the documents. One of the reasons for it is the difficulty in understanding those notions and in their implementation in classrooms. The present work intends to clarify some of the main ideas contained in the PCN and PCN+, namely, the notion of competences, interdisciplinarity and contextualization, from the point of view of their authors, more specifically in the area of Natural Sciences, Mathematics and their Technologies. For this, semi-structured interviews were used. The thesis that there is a rupture between the DCNEM and the National Curricular Parameters, as far as educational, political and philosophical aspects are concerned, is also argued for.

    Full Text Available Identity is composed by values, beliefs and goals to which an individual is committed. There are four states of identity determined according to the exploration of alternatives and the intensity of commitment: diffusion, foreclosure, moratorium and achievement. This work evaluated the identity states of 753 Brazilian adolescents from 15 to 18 years old who study in public schools in the city of São Paulo. They responded to the Extended Objective Measure of Ego Identity Status (EOMEIS 2 a kind of Likert scale that measures states of identity. Most adolescents were in moratorium state. A positive association was identified between the female gender and both the states of moratorium and achievement, as well as, between the first year of high school and foreclosure.

  6. Evaluating fire danger in Brazilian biomes: present and future patterns

    2017-04-01

    Climate change is expected to have a significant impact on fire occurrence and activity, particularly in Brazil, a region known to be fire-prone [1]. The Brazilian savanna, commonly referred to as cerrado, is a fire-adapted biome covering more than 20% of the country's total area. It presents the highest numbers of fire events, making it particularly susceptible to changes in climate. It is thus essential to understand the present fire regimes in Brazilian biomes, in order to better evaluate future patterns. The CPTEC/INPE, the Brazilian Center for Weather Forecasting and Climate Research at the Brazilian National Institute of Space Research developed a fire danger index based on the occurrence of hundreds of thousands of fire events in the main Brazilian biomes [2]: the Meteorological Fire Danger Index (MFDI). This index indicates the predisposition of vegetation to be burned on a given day, for given climate conditions preceding that day. It relies on daily values of air temperature, relative humidity, accumulated precipitation and vegetation cover. In this study we aim to access the capability of the MFDI to accurately replicate present fire conditions for different biomes, with a special focus on cerrado. To this end, we assess the link between the MFDI as calculated by three different reanalysis (ERA-Interim, NCEP/DOE Reanalysis 2 and MERRA-2) and the observed burned area. We further calculate the validated MFDI using a regional climate model, the RCA4 as forced by EC-Earth from CORDEX, to understand the ability of the model to characterize present fire danger. Finally, the need to calibrate the model to better characterize future fire danger was also evaluated. This work was developed within the framework of the Brazilian Fire-Land-Atmosphere System (BrFLAS) Project financed by the Portuguese and Brazilian science foundations, FCT and FAPESP (project references FAPESP/1389/2014 and 2014/20042-2).

    Full Text Available The theme of corporate social responsibility (CSR has not been widely examined in the context of multinationals. This dearth is even greater with respect to subsidiaries, particularly the subject of reverse transfer of practices, that is, the transfer of practices developed in subsidiaries back to the parent company. Because of this theoretical gap, the present article investigates the factors involved on reverse transfer of CSR practices. The research hypotheses test the importance of developing nonlocation-bound capabilities, of integration between subsidiaries and parent and of institutional distance. The data were obtained by a survey of the main foreign subsidiaries in Brazil. All told, we analyzed 150 Brazilian subsidiaries of multinationals, by applying multiple linear regression. The results indicate that the reverse transfer of CSR depends on the development of nonlocation-bound capabilities of the subsidiaries and integration between the parent company and its foreign subsidiaries.

    In order to improve radiation protection it is necessary to have knowledge of the occupational radiation dose levels in all radiation facilities. This information comes from individual monitoring services, which are responsible for measuring and providing information about workers' radiation exposure. In 1981, the Comissao Nacional de Energia Nuclear (CNEN) of Brazil starts to develop a comprehensive system for regulation and storage of occupational radiation dose. This paper starts with an overview of the evolution of the Brazilian authorization and data storage system for external individual monitoring. It starts with a rule for authorization of all Brazilian photon individual monitoring services and the obligation for them to send the measured dose to CNEN. Up to now there is no regulation for neutron individual monitoring. The aim of this paper is to present the current scenario of the Brazilian external monitoring system, reinforcing its importance and remaining problems. The number of monitored workers greatly increases every year, having surpassed 150,000 people monitored. The stored data show that the mean annual occupational external dose is decreasing from 2.4 mSv in 1987 to about 0.6 mSv, in 2012, but there is still some not realistic very high dose measured (higher than 100 mSv), without investigation. About 80% of the annual dose values are lower than the monthly register level. As expected, the higher real photon doses are found in Nuclear Medicine, Industrial Radiology and Interventional Radiology. All recorded annual neutron dose values are lower than 20 mSv. (author)

    The effects of the addition of different strains of lactic acid bacteria on different quality parameters of a Brazilian goat semi-hard cheese (coalho) were assessed during 7 days of storage (10°C) as follows: Control, Lactobacillus lactis subsp. lactis and L. lactis subsp. cremoris (standard); C2, L. acidophilus; C3, L. paracasei; C4, Bifidobacterium lactis; and C5, L. acidophilus, L. paracasei and B. lactis. There were no differences for the proteolysis index and depth of proteolysis among the assessed cheeses. The cheeses presented increase in hardness, gumminess and chewiness during the storage. Regarding the ability to melt, all evaluated cheeses showed a reduction in diameter. Cheeses presented high luminosity with predominance of the yellow component; and number of lactic bacteria greater than 10⁶-10⁷ cfu/g during the 7 days of storage. C5 had better sensory scores in the acceptance test, purchase intention and preference ranking test. Coalho goat cheese could be a potential carrier of probiotic lactic acid bacteria.

    Both the national domain of the technology for the separation of rare earth elements and the large reserves of these minerals in Brazilian territory, motivated the study of national sheets scintillators converter of neutrons, using a granular mixture Gd{sub 2}O{sub 3}-Zn S:Ag. Three methodologies were used for the manufacture of such sheets, namely: deposition done with a compressed-air gun on a sheet of cellulose type CG3460-3M; fusion of granular mixture with EVA in the mixing chamber and deposition of granular mixture on the substrate of EVA. It was used the flux of the order of 4,46 x 10{sup 5} neutrons thermic/cm{sup 2}.s, coming from the channel irradiation, J-9, of the reactor Argonauta/IEN/CNEN and the radiographic film AA-400 Kodak Industrex. The performances of national scintillator neutrons converter sheets were analyzed and the images obtained with the, demonstrated that the methodologies proposed are technically feasible and can contribute to the reduction of cost of this technique for NDA, but which lack optimization is aimed at increasing the number of photons of light to allow its use in neutrongraphies in Real Time (NRTR).

    Few studies have focused on the quality of life (QoL) of patients with disorders of sex development (DSD). Our aim was to evaluate QoL in DSD patients with defined diagnoses followed until adulthood in a single tertiary centre. Adult patients with DSD (56 patients with 46,XX DSD - 49 with female social sex and 7 with male social sex as well as 88 patients with 46,XY DSD - 54 with female social sex and 34 with male social sex). QoL using WHOQOL-Bref questionnaire. Both patients with 46,XX DSD and patients with 46,XY DSD had similar QoL scores on the WHOQOL-Bref, comparable to the scores of the Brazilian general population. The chronological age at the start of treatment was negatively and significantly associated with general QoL score. Patients with male social sex DSD had better scores on the psychological domain than patients with female social sex DSD, as found in the Brazilian general population. In addition, among the 46,XY DSD group, the male social sex patients had better QoL compared with the female social sex patients. There was a positive and significant correlation between sexual performance and general QoL, although it explained only 4% of the variability of the general QoL score. The most influencing variables were general health, positive feelings and spirituality, religion and personal beliefs, each of them contributing with 18% of the variability of the general QoL score. Our large cohort of adult patients with DSD, which was followed by a multidisciplinary team in a single tertiary centre, had good QoL in adulthood; in addition, late treatment compromised the QoL of patients with DSD, whereas sexual performance has little influence on QoL. © 2014 John Wiley & Sons Ltd.

    The electronic ballot box has played a significant role in the consolidation of Brazilian political process. It has enabled paper ballots extinction as a support for the elector's vote as well as for voting counting processes. It is also widely known that election automation has decisively collaborated to the legitimization of Brazilian democracy, getting rid of doubts about the winning candidates. In 1995, when the project was conceived, it represented a compromise solution, balancing technical efficiency and costs trade-offs. However, this architecture currently limits the ergonomic enhancements to the device operation, transportation, maintenance and storage. Nowadays are available in the market devices of reduced dimensions, based on novel computational architecture, namely tablet computers, which emphasizes usability, autonomy, portability, security and low power consumption. Therefore, the proposal under discussion is the replacement of the current electronic ballot boxes for tablet-based devices to improve the ergonomics aspects of the Brazilian voting process. These devices offer a plethora of integrated features (e.g., capacitive touchscreen, speakers, microphone) that enable highly usable and simple user interfaces, in addition to enhancing the voting process security mechanisms. Finally, their operational systems features allow for the development of highly secure applications, suitable to the requirements of a voting process.

    To assess the current practices in gout management among Brazilian rheumatology residents. We performed a cross-sectional online survey among all the rheumatology residents and those rheumatologists who had just completed their training (post-residency (PR)) regarding their approach to gout management. Results were compared with the 2012 American College of Rheumatology (ACR) gout guidelines and with the responses of a previous survey with a representative sample of practicing Brazilian rheumatologists (RHE). We received 224 responses (83%) from 271 subjects. Among all respondents, the first-choice treatment for gout flares was the combination of a nonsteroidal anti-inflammatory drug + colchicine for otherwise healthy patients. A target serum urate 75%. Less than 70% reported starting allopurinol at low doses (≤100 mg/day) for patients with normal renal function and gout guidelines, especially among PR. However, some important aspects of gout management need improvement. These results will guide the development of a physician education program to improve the management of gout patients in Brazil.

  19. Passages on Brazilian scientific cinema.

    de Almeida, Jane; da Silva, Cicero Inacio; Suppia, Alfredo; Stalbaum, Brett

    2017-07-01

    The article examines the conditions of production and recognition of scientific cinema in Brazil by comparing three distinct moments and contexts: the first moment takes place in the nineteenth century, and it is related to the contribution of a Brazilian astronomer otherwise little known to Brazilian film scholars, the second addresses Benedito Junqueira Duarte's voluminous mid-twentieth-century filmography, and the third moment documents recent scientific film experiences within ultra high resolution movies transmitted over photonic networks. Future trajectories for aesthetic concerns and practical issues such as the archiving of ultra high definition cinema are usefully informed by these histories of scientific cinema, even as a current generation of multidisciplinary teams including scientists, filmmakers, computer scientists, and network engineers reinvent, rediscover, and necessarily expand the scientific cinema toward concerns of real time collaboration and teaching.

    Full Text Available With one of the most notable floras in the world for sustainable research, the Brazilian Amazon region currently counts on financial incentives from the Brazilian Government for private national and foreign businesses. The ongoing implantation of a Biocosmetics Research and Development Network (REDEBIO aims to stimulate research involving natural resources from the Brazilian states that make up the zone defined as “Amazônia Legal”. The objective of this region, still under development in Brazil, is principally to aggregate value to products manufactured in small local industries through the use of sustainable technology currently being established. Certain certified raw materials already included in the country’s sustainability program, have also begun to be cultivated according to the requirements of organic cultivation (Neves, 2009. The majority are species of Amazonian vegetation: Euterpe oleracea (Açai, Orbignya martiana (Babaçu, Theobroma grandi-florum (Cupuaçu, Carapas guianensis (Andiroba, Pentaclethra macroloba (Pracaxi, Copaifera landesdorffi (Copaiba, Platonia insignis (Bacuri, Theobroma cacao (Cacao, Virola surinamensis (Ucuuba and Bertholletia excelsa (Brazil nut. These generate phytopreparations, such as oils, extracts, and dyes that are widely used in the manufacture of Brazilian organic cosmetics with scientifically proven topical and capillary benefits. In the final balance, Brazilian organic cosmetics should continue to gain force over the next few years, especially with the regulation of the organic cosmetics market that is being drafted by the Brazilian Ministry of Agriculture. Moreover, lines of ecologically aware products that provide quality of life for both for rural and metropolitan communities show a tendency to occupy greater space in the market.

    Full Text Available Significant progress has been obtained since the Second Brazilian Consensus Conference on Helicobacter pylori Infection held in 2004, in São Paulo, SP, Brazil, and justify a third meeting to establish updated guidelines on the current management of H. pylori infection. The Third Brazilian Consensus Conference on H pylori Infection was organized by the Brazilian Nucleus for the Study of Helicobacter, a Department of the Brazilian Federation of Gastroenterology and took place on April 12-15, 2011, in Bento Gonçalves, RS, Brazil. Thirty-one delegates coming from the five Brazilian regions and one international guest, including gastroenterologists, pathologists, epidemiologists, and pediatricians undertook the meeting. The participants were allocated in one of the five main topics of the meeting: H pylori, functional dyspepsia and diagnosis; H pylori and gastric cancer; H pylori and other associated disorders; H pylori treatment and retreatment; and, epidemiology of H pylori infection in Brazil. The results of each subgroup were submitted to a final consensus voting to all participants. Relevant data were presented, and the quality of evidence, strength of recommendation, and level of consensus were graded. Seventy per cent and more votes were considered as acceptance for the final statement. This article presents the main recommendations and conclusions to guide Brazilian doctors involved in the management of H pylori infection.

    2014-10-01

    The objective of Brazilian Eratosthenes Project is the development and application of teaching training actions according the ``docent autonomy" concept to basic Astronomy Education. Argentina coordinates the project in South America, but Brazil works in this project since 2010 with the theme ``Projeto Eratóstenes Brasil" in the homepage: http://sites.google.com/site/projetoerato. Two schools measure a sticks shadow and communicate their results. After, they calculate an average radius of Earth. The stick (gnomon) should stay in vertical position in the leveled ground. Since 2010, the project received hundreds of Brazilian schools with different experiments that were constructed with autonomy, because our site doesn't show some itinerary pre-ready to elaborate the experiments. To collect data for our research, we will use interviews via Skype with the teachers. These data are useful to researches about Science Education area and the Teaching Formation. Teaching professional practice could change and we see modifications in the teachers work, what depends of their realities and context. This project intents to respect the docent autonomy. This autonomy to responsible modifications during continued formation is called ``activist formative model" according Langhi & Nardi (Educação em Astronomia: repensando a formação de professores. São Paulo: Escrituras Editora, 2012). This project discusses about researches in Astronomy Education - still extreme rare in Brazil, when we compare with other areas in Science Education. We believe that actions like this could motivate the students to learn more Astronomy. Furthermore, this national action can be a rich source of data to investigations about teaching formation and scientific divulgation.

    Makundi, W.; Sathaye, J. [eds.] [Lawrence Berkeley Lab., CA (United States); Fearnside, P.M. [Instituto Nacional de Pesquisas da Amazonia (INPA), Manaus, AM (Brazil). Departmento de Ecologia

    1992-08-01

    Deforestation in Brazilian Amazonia in 1990 was releasing approximately 281--282 X 10{sup 6} metric tons (MT) of carbon on conversion to a landscape of agriculture, productive pasture, degraded pasture, secondary forest and regenerated forest in the proportions corresponding to the equilibrium condition implied by current land-use patterns. Emissions are expressed as ``committed carbon,`` or the carbon released over a period of years as the carbon stock in each hectare deforested approaches a new equilibrium in the landscape that replaces the original forest. To the extent that deforestation rates have remained constant, current releases from the areas deforested in previous years will be equal to the future releases from the areas being cleared now. Considering the quantities of carbon dioxide, carbon monoxide, methane, nitrous oxide, NO{sub x} and non-methane hydrocarbons released raises the impact by 22--37%. The relative impact on the greenhouse effect of each gas is based on the Intergovernmental Panel on Climate Change (IPCC) calculations over a 20-year time period (including indirect effects). The six gases considered have a combined global warming impact equivalent to 343 to 386 million MT of C0{sub 2}-equivalent carbon, depending on assumptions regarding the release of methane and other gases from the various sources such as burning and termites. These emissions represent 7--8 times the 50 million MT annual carbon release from Brazil`s use of fossil fuels, but bring little benefit to the country. Stopping deforestation in Brazil would prevent as much greenhouse emission as tripling the fuel efficiency of all the automobiles in the world. The relatively cheap measures needed to contain deforestation, together with the many complementary benefits of doing so, make this the first priority for funds intended to slow global warming.

    2015-07-01

    Food waste (FW) related issues in developing countries is currently considered to be a major threatening factor for sustainable development and FW management systems. Due to incomplete FW management systems, many developing countries are facing challenges, such as environmental and sanitary problems that are caused by FW. The difference in FW generation trends between developing countries and developed countries was reviewed in this work, which demonstrated that the effects of income level, population growth, and public participation in FW management are very important. Thus, this work aimed to provide an overview of recycling activities, related regulations, and current FW treatment technology in developing countries by following some case studies. Taiwan, has been suggested as being a successful case in terms of FW management, and is therefore a typical model for developing countries to follow. Finally, an integrative management system as a suitable model for FW management has been suggested for developing countries. Copyright © 2015 Elsevier Ltd. All rights reserved.

  14. Development and validation of a stability indicating method for quantification of the sesquiterpene lactone eremantholide C from Lychnophora trichocarpha (Brazilian arnica

    Directory of Open Access Journals (Sweden)

    Bárbara O. Henriques

    Full Text Available ABSTRACT Pharmacological activities as anti-inflammatory, anti-hyperuricemic, anti-gouty arthritis, antitumor and trypanocidal activities of the aerial parts from Lychnophora trichocarpha (Spreng. Spreng. ex Sch.Bip., Asteraceae (Brazilian arnica have already been proved. Eremantholide C is a sesquiterpene lactone and one of the active chemical constituents responsible for these activities presented by L. trichocarpha. Therefore, the aim of this work was to develop and validate a stability indicating HPLC method for eremantholide C. Eremantholide C stability was evaluated in L. trichocarpha ethanolic extract and in its isolated form. Analytical conditions employed C18 column, acetonitrile/water in gradient elution, flow of 0.8 ml/min at 30 ºC. To correct for the loss of analyte during sample preparation the use of coumarin as an internal standard was necessary. The developed method provides good separation and resolution of the peaks, allowing quantification of eremantholide C, isolated or directly in the ethanolic extract, in internal standard presence. Validation results showed that this method is linear in the concentration range 2–180 µg/ml, precise, accurate and specific. Stability studies showed that L. trichocarpha ethanolic extract and eremantholide C remain stable for 6 months when stored at room temperature and impermeable glass bottle, therefore they can be used safely and effectively within this period. While at 40 ºC there was stability loss, at 8 ºC a stability increase was observed for the extract and the isolated eremantholide C. Forced degradation studies showed that eremantholide C degraded under acidic and alkaline conditions and was stable for three days under neutral and oxidative conditions, and when exposed to high temperature. Thus, with the development of a stability indicative method and the application of it in eremantholide C stability studies, the results can guide the development of new products that

  15. What the Current System Development Trends tell us about Systems Development Methodologies: Toward explaining SSDAM, Agile and IDEF0 Methodologies

    Directory of Open Access Journals (Sweden)

    Abdulla F. Ally

    2015-03-01

    Full Text Available Systems integration, customization and component based development approach are of increasing attention. This trend facilitates the research attention to also focus on systems development methodologies. The availability of systems development tools, rapid change in technologies, evolution of mobile computing and the growth of cloud computing have necessitated a move toward systems integration and customization rather than developing systems from scratch. This tendency encourages component based development and discourages traditional systems development approach. The paper presents and evaluates SSADM, IDEF0 and Agile systems development methodologies. More specifically, it examines how they fit or not fit into the current competitive market of systems development. In the view of this perspective, it is anticipated that despite of its popularity, SSADM methodology is becoming obsolete while Agile and IDEF0 methodologies are still gaining acceptance in the current competitive market of systems development. The present study more likely enrich our understanding of the systems development methodologies concepts and draw attention regarding where the current trends in system development are heading.

    2017-04-01

    Although reclamation techniques for forest ecosystems recovery have been developed over the past decades, there is still a great difficulty in the establishment on environment assessment, especially when compared to the non-disturbed ecosystems. This work evaluated the results and limitations on cassiterite-mined areas in reclamation, at Brazilian Amazônia. Floristic variables from 29 plots located on 15-year-old native species reforestation sites and two plots from preserved open/closed canopy forests were analyzed in a chronosequece way (2010-2015). Regeneration density, species richness, average girth, and average height were evaluated every year, by means of cluster analysis (Euclidian distance, Ward method) and submitted to multiscale bootstrap resampling (a=5%). It was conduced the regression analysis for each identified group in 2015 in order to verify differences between the chronosequece development. The results showed the existence of two main groups in 2010, one witch all mined plots were allocated and other with open/closed canopy plots. After 2011 some mined areas became allocated in the open/closed canopy plots group. From 2013 and on open/closed canopy plots appeared shuffled in the formed groups, indicating the reclamation sites conditions became similar to natural areas. Finally, in 2015 three main groups were formed. The regression analysis showed that group three had a higher trend of development for regeneration density, with higher angular coefficient and higher values. For species richness all the groups had a similar trend, with values lower than open/closed canopy forest. In average girth higher trends were observed in group one and all values were near to open canopy forest in 2015. Average height showed better trends and higher values in group two. It was concluded that all mined sites had a forest recovery process. However, different responses to reclamation process were observed due to the differences in the degraded soils

  18. A Constructivist Perspective on Leadership Thought among Brazilian and North-American Scholars

    Directory of Open Access Journals (Sweden)

    Anderson de Souza Sant'Anna

    2011-04-01

    Full Text Available This paper presents the results of an exploratory, inductive cataloguing of the views of Brazilian and U.S. academics regarding current leadership theory and development. Semi structured interviews with academics from a variety of institutional settings in Brazil and the U.S. were content analyzed to identify major themes and tendencies across the two countries. Our analyses revealed that neither Brazilian nor U.S. academics adopted the bulk of current formal leadership thought uncritically. Instead, both the Brazilian and North American business education fields adopted theories selectively and formulated idiosyncratic approaches to the field. The U.S. interviewees appeared to vary much more from one another than the Brazilian scholars, whose positions were more critical but more homogeneous overall. There was also considerable variation across the two national settings. We found Bourdieu’s practice theory useful in interpreting our results, particularly the concepts of field differentiation and heteronomy, habitus, and cultural capital. Still, much research remains to be done to disentangle the purely historical and cultural factors from the impacts of the social construction of the field of business education in the two countries.

    The aim of this paper is to analyse the capacity of the 'inflexible production', by state-owned Brazilian company PETROBRAS at its natural gas-based thermo-electrical generation stations, to promote in a increase in the use of the Brazil- Bolivia Gaspipe (Gasbol), which is the natural gas transport pipe related to 90,66% of the Brazilian natural gas imports. As the contract is a 'take or pay' contract, Brazil ends up paying for such a large volume of gas that the country does not effectively consume, since the consume of natural gas in Brazil has not come to the expectations which were prevailing when the import contract was signed. Last but not least, this article addresses the future possibilities for the increase of the share of natural gas in the total Brazilian energy consumption. (author)

    2018-01-01

    This study compared three methods designed for age estimation. A sample of 468 radiographs (234 panoramic and 234 carpal radiographs) collected from patients ranging from 5 to 14 years old (mean age: 11.27years old±2.27years) was used. Three age estimation methods: were applied: one founded on dental development, one founded on hand and wrist development, and a method combining both measurements. For each method, the mean error (ME), mean absolute error (MAE), root mean square error (RMSE), and mean percentage of absolute error (MPAE) were quantified. The methods: were compared based on their effectiveness for estimating age in relation to sex and age range. The data show that the method exclusively using the development of the hand and wrist had the highest error rates (ME: 1.28M, 1.85F; MAE: 1.64M, 1.96F; RMSE: 1.94M, 2.32F) for both males (M) and females (F). In males, the method combining dental and skeletal development obtained outcomes that were slightly better than the method founded on only dental development (MPAE: 6.99% and 7.47%, respectively). In females, the opposite result was observed (MPAE: 8.48% and 6.59%, respectively). The method founded exclusively on skeletal development significantly overestimated (p=0.001) the age (mean chronological and estimated ages: 11.27 and 12.88, respectively). The methods involving dental development provided more accurate age estimates of chronological age. The method exclusively based on hand and wrist development resulted in outcomes that were highly discrepant from the chronological age. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2012-01-01

    The Mediterranean fruit fly Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) is one of the principal exotic pests affecting Brazilian production in the northeastern and southeastern regions of Brazil. In the south, it is has potential as a serious threat to temperate-climate fruit farms, since it is already found in urban and suburban communities in this region. We studied the biological characteristics of C. capitata populations from Pelotas-RS (temperate climate), Petrolina-PE (tropical), and Campinas-SP (subtropical). Ceratitis capitata biology was studied under controlled temperature (15, 20, 25, 30, and 35 ± 1 °C), 70 ± 10% RH, and 14:10 L:D photoperiod. The duration and survival rate of the egg, larval, and pupal stages were evaluated and the thermal requirements of these three populations were determined. The duration and survival of these developmental stages varied with temperature, with similar values for the three populations, except for some variation in the egg phase. Egg to adult developmental time for all three populations was inversely proportional to temperature; from 15 to 30 °C developmental time varied from 71.2 to 17.1, 70.2 to 17.1, and 68.5 to 16.9 days, respectively. Survival during development was affected at 15 to 30 °C, and differed significantly from survival at 20 to 25 °C. At 35 °C, immature stages did not develop. The basal temperature and degree-day requirement were similar for all immature stages except for the egg stage. The basal temperatures and thermal constants were 9.30 and 350, 8.47 and 341, and 9.60 °C and 328 degree-days for the Pelotas, Petrolina, and Campinas populations, respectively. Results suggested that survival and thermal requirements are similar for these tropical, subtropical, and temperate populations of C. capitata, and demonstrate the species' capacity to adapt to different climate conditions.

    The Mediterranean fruit fly Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) is one of the principal exotic pests affecting Brazilian production in the northeastern and southeastern regions of Brazil. In the south, it is has potential as a serious threat to temperate-climate fruit farms, since it is already found in urban and suburban communities in this region. We studied the biological characteristics of C. capitata populations from Pelotas-RS (temperate climate), Petrolina-PE (tropical), and Campinas-SP (subtropical). Ceratitis capitata biology was studied under controlled temperature (15, 20, 25, 30, and 35 ± 1 °C), 70 ± 10% RH, and 14:10 L:D photoperiod. The duration and survival rate of the egg, larval, and pupal stages were evaluated and the thermal requirements of these three populations were determined. The duration and survival of these developmental stages varied with temperature, with similar values for the three populations, except for some variation in the egg phase. Egg to adult developmental time for all three populations was inversely proportional to temperature; from 15 to 30 °C developmental time varied from 71.2 to 17.1, 70.2 to 17.1, and 68.5 to 16.9 days, respectively. Survival during development was affected at 15 to 30 °C, and differed significantly from survival at 20 to 25 °C. At 35 °C, immature stages did not develop. The basal temperature and degree-day requirement were similar for all immature stages except for the egg stage. The basal temperatures and thermal constants were 9.30 and 350, 8.47 and 341, and 9.60 °C and 328 degree-days for the Pelotas, Petrolina, and Campinas populations, respectively. Results suggested that survival and thermal requirements are similar for these tropical, subtropical, and temperate populations of C. capitata, and demonstrate the species' capacity to adapt to different climate conditions.

    We present a new version of the Brazilian developments on the Regional Atmospheric Modeling System (BRAMS), in which different previous versions for weather, chemistry, and carbon cycle were unified in a single integrated modeling system software. This new version also has a new set of state-of-the-art physical parameterizations and greater computational parallel and memory usage efficiency. The description of the main model features includes several examples illustrating the quality of the transport scheme for scalars, radiative fluxes on surface, and model simulation of rainfall systems over South America at different spatial resolutions using a scale aware convective parameterization. Additionally, the simulation of the diurnal cycle of the convection and carbon dioxide concentration over the Amazon Basin, as well as carbon dioxide fluxes from biogenic processes over a large portion of South America, are shown. Atmospheric chemistry examples show the model performance in simulating near-surface carbon monoxide and ozone in the Amazon Basin and the megacity of Rio de Janeiro. For tracer transport and dispersion, the model capabilities to simulate the volcanic ash 3-D redistribution associated with the eruption of a Chilean volcano are demonstrated. The gain of computational efficiency is described in some detail. BRAMS has been applied for research and operational forecasting mainly in South America. Model results from the operational weather forecast of BRAMS on 5 km grid spacing in the Center for Weather Forecasting and Climate Studies, INPE/Brazil, since 2013 are used to quantify the model skill of near-surface variables and rainfall. The scores show the reliability of BRAMS for the tropical and subtropical areas of South America. Requirements for keeping this modeling system competitive regarding both its functionalities and skills are discussed. Finally, we highlight the relevant contribution of this work to building a South American community of model

    This paper reports that the authors have developed and tested a 6.6 kV/1.5 kA-class fault current limiter wound with a 42-strand AC superconducting wire having ultra-fine MbTi filaments in a high resistivity matrix. In experiments, voltages up to 7.2 kV were applied to the limiter with phase angles of 0, 45, and 90 degrees. The limiter was able to limit the fault current to 1.8 kA successfully from the 55 kA short-circuit current that would flow in a circuit without limiter.

    A multi-site, multi-device and multi-criteria decision support tool designed to support the development of tidal current energy in the Philippines was developed. Its platform is based on Geographic Information Systems (GIS) which allows for the collection, storage, processing, analyses and display of geospatial data. Combining GIS tools with open source web development applications, it becomes a webGIS-based marine spatial planning tool. To date, the webGIS-based tool displays output maps and graphs of power and energy density, site suitability and site-device analysis. It enables stakeholders and the public easy access to the results of tidal current energy resource assessments and site suitability analyses. Results of the initial development showed that it is a promising decision support tool for ocean renewable energy project developments.

    Full Text Available ABSTRACT Current meters are equipment widely used for estimating flow velocity in rivers and streams. Periodic calibrations of current meters are important to ensure the quality of measurements, but the required testing facilities are complex and only available in a few institutions. However, advances in electronics and automation may contribute to developing simple and reliable calibration systems. Thus, this study aimed to develop an automated system for testing current meters, which consisted of a trapezoidal channel, a step motor, a tow car and a management system, composed of a supervisory application and microprocessed modules to control the motor and the data acquisition. Evaluations of the displacement velocity showed that it matched the reference value up to 1.85 m s-1 for a vertical-axis current meter and 2.3 m s-1 for a horizontal-axis one. The developed system showed reliability during tests, for both current meter movement and data acquisition. The management of the system based on the developed modules and the supervisory application improved its user interface, turning all the procedure into a simple task.

    Full Text Available The territory ‘Meio Oeste Contestado’, located in Santa Catarina, Brazil, was created in 2003, after the implementation of the rural territorial development policy of the government of Luiz Inácio Lula da Silva (2003-2010. This article analyzes how social and political relations were established and administered in the territory; how the disputes between different actors and interests were dealt with; the ideas and interpretations that were at stake; and what territorial rules and regulations were established for the negotiation and conciliation between the different social actors. In general, we observe that the ideas that the territorial actors have about public policies for rural territorial development differ from those of the federal government. The main interest of the different actors in the territority is to raise more financial resources for the local organizations and municipalities in the territory due to the fragile nature of the different territorial institutions.

    Despite strong evidence for a relationship between high salt intake and hypertension, plus the widespread recommendations for dietary salt restriction among hypertensive subjects, there are no nursing studies describing effective theory-based interventions. To describe a systematic process for development of a theory-based nursing intervention that is aimed at reducing salt intake among hypertensive women, by applying the 'intervention mapping' protocol. We developed our intervention following the six steps of the 'intervention mapping' protocol: assessing needs, creating a matrix of change objectives, selecting theoretical methods and practical applications, defining the intervention programme, organizing the adoption and implementation plan, and defining the evaluation plan. Addition of salt during cooking is identified as the main source for salt consumption, plus women are identified as the people responsible for cooking meals at home. In our study, the motivational predictors of this behaviour were self-efficacy and habit. Guided practice, verbal persuasion, coping barriers, consciousness-raising and counter-conditioning were the theoretical methods we selected for enhancing self-efficacy and promoting habit change, respectively. Brainstorming, role-playing, cookbook use, measuring spoon use, label reading, hands-on skill-building activities and reinforcement phone calls were the chosen practical applications. We designed our intervention programme, and then organized the adoption and implementation plans. Finally, we generated a plan to evaluate our intervention. 'Intervention mapping' was a feasible methodological framework to guide the development of a theory-based nursing intervention for dietary salt reduction among hypertensive women.

  14. Agroecology, Public Policies and Labor-Driven Intensification: Alternative Development Trajectories in the Brazilian Semi-Arid Region

    Directory of Open Access Journals (Sweden)

    Paulo F. Petersen

    2017-03-01

    Full Text Available The institutional recognition obtained by family farming in Brazil over recent decades has translated into the launching of a broad and diverse set of public policies specifically aimed towards this sociopolitical category. However, the design of these policies was heavily influenced by the productivist bias derived from the agricultural modernization paradigm, making the sector increasingly dependent on input and capital markets. In this same movement of institutional evolution, policies consistent with the agroecological approach created new margins for maneuvering for development trajectories founded on the use of local resources self-controlled by rural families and communities. Taking as a reference the recent trajectory of rural development in Brazil’s semi-arid region, the article analyses the role of the agroecological perspective in the strategic combination between territorially endogenous rural resources and public resources redistributed by the State. Based on the analysis of the economy of agroecosystems linked to two sociotechnical networks structured by contrasting logics of productive intensification, the study demonstrates agroecology’s potential as a scientific-technological approach for the combined attainment of various Sustainable Development Goals, starting with the economic and political emancipation of the socially most vulnerable portions of the rural population.

    There is an increased need for capacity building of researchers and professionals in low- and middle-income countries with evidence-based approaches across the tobacco control continuum, particularly with regard to gender-relevant strategies. We describe the development, implementation, and evaluation of a Career Development and Research Training Program (CDRTP) in tobacco control. The CDRTP is organized into two modules: Module I is open to the public and provides an overview of tobacco control; Module II, consists of a one-year program with multi-mode sessions toward the development of a pilot research project. Activities are implemented through co-learning to facilitate cross-fertilization of knowledge, collaborations, and team science. Between 2010 and 2015, 255 individuals participated in Module I with 57 applying for Module II's selective process. Out of these, 35 were selected, 29 completed the program (83%), 21 submitted pilot research projects that have undergone review, and 16 were approved for funding. Pre- and post-tests among the 29 participants who completed the training indicated improvement in scholars' perceived knowledge and skills on all of the components. In addition to attracting researchers and professionals who have not been working in tobacco control, the capacity building program has promoted knowledge, skills, and confidence among participants to pursue gender-relevant tobacco control research.

    Brazilian society declares no intention to development a nuclear artifact. This is on its Constitution. The submarine of nuclear propulsion may be used as a weapon of defense and, therefore, has a peaceful objective. Nationalism must be applied only to benefit the society. Nationalist attention has always been devoted, at various occasions, to the Brazilian nuclear sector. However, since Brazilian society has many needs and the Brazilian government always had numerous energy options, this sector has not been developed as it could be. Other successful applications of nuclear technology, besides electric generation, are not considered here. At present, the country is experiencing a moment of harassment of liberal forces. It is difficult to know if the population understands what is going on, due to the traditional media control. This media belongs to the capital. The rise and the fall of the nationalist strand in a country follow a global tendency and also depend of actions of the international capital. In nationalist periods, more decisions with positive social impact are taken. Therefore, sovereignty is necessary to increase the benefits to society. Unfortunately, the Brazilians deceived by the companies of mass communication and corrupt political leaderships allow the country to be dominated. Even the armed forces had their projects paralyzed. The nuclear sector, as all other, suffers with the low budget and the future is difficult to predict. (author)

  17. A new 3D fully wave-current model MARS-WAVEWATCH : development, validation and application to the rip currents

    2010-12-01

    The interaction of waves with three-dimensional current structure is investigated using a two-way coupled modelling system combining MARS3D (Lazure and Dumas 2008) with WAVEWATCH III (Tolman 2008, Ardhuin et al. 2009) , a wave model (NOAA/NCEP, Tolman 2008). After a basic validation in two dimensions, the flow model MARS3D was adapted with three options that solve for the total momentum (Mellor 2003, 2008) or the quasi-Eulerian momentum (Ardhuin et al. 2008b). Adiabatic model results show that, as expected from theory (Ardhuin et al. 2008a), the total momentum fluxes parameterized by Mellor are not self-consistent and can lead to very large errors (Bennis and Ardhuin 2010). We thus use the model option to solve for the quasi-Eulerian momentum, including sources of momentum and turbulent kinetic energy (TKE). The influence of these TKE sources is investigated in the case of the NSTS experiment (Thornton and Guza, 1986). The feedback of the currents on the waves is negligible in this case. The sources of TKE from wave breaking and wave bottom friction are found to have strong influence on the bottom friction, in a way consistent with the parameterizations by Longuet-Higgins (1970) and Mellor (2002). The complete model is then applied to a real case of a large rip current on the South-West coast of France (Bruneau et al., Cont. Shelf Res. 2009). The breaking of waves on the opposed current generates a strong coupling on the rip current that partially controls the strength of the current and it three-dimensional shape.

    2014-05-01

    Full Text Available The direct methanol fuel cell (DMFC adopts methanol solution as a fuel suitable for low power portable applications. A miniature, lightweight, passive air-breathing design is therefore desired. This paper presents a novel planar disc-type DMFC with multiple cells containing a novel developed lightweight current collector at both the anode and cathode sides. The present lightweight current collector adopts FR4 Glass/Epoxy as the substrate with the current collecting areas located at the corresponding membrane electrolyte assembly (MEA areas. The current collecting areas are fabricated by sequentially coating a corrosion resistant layer and electrical conduction layer via the thermal evaporation technique. The anode current collector has carved flow channels for fuel transport and production. The cathode current collector has drilled holes for passive air breathing. In order to ensure feasibility in the present concept a 3-cell prototype DMFC module with lightweight disc type current collectors is designed and constructed. Experiments were conducted to measure the cell performance. The results show that the highest cell power output is 54.88 mW·cm−2 and successfully demonstrate the feasibility of this novel design.

    Los Alamos is extending the performance of the Friedman-type, high-current relativistic klystron amplifier (RKA) to the microsecond regime while attempting to achieve the gigawatt-level peak power capability that has been characteristic of the RKA at shorter pulse lengths. Currently the electron beam power into the device is about 1 GW in microsecond duration pulses, with an effort underway to increase the beam power to 2.5 GW. To date the device has yielded an RF modulated electron beam power of 350 MW, with up to 50 MW coupled into the waveguide. Several aspects of RKA operation under investigation that affect RKA beam bunching efficiency and amplifier gain include cavity tuning, beam diameter, beam current, and input RF drive power, and the development of an output coupler that efficiently couples the microwave power from the low impedance beam into rectangular waveguide operating in the dominant mode. Current results from experimental testing and code modelling are presented.

    A fault detection system is applied to power lines consisting of both overhead power line and underground power cable in order to detect a fault on the underground power cable section and prevent the automatic reclosing. The fault detection system using optical fiber current sensor has two subjects. The fist subject is that we have to use wound-type current transformer together, when applying the fault detection system to single-core underground power cable. The second subject is that we are not able to detect three-phase short-circuit fault in using the fault detection system. This paper describes that we developed a new fault detection system using optical fiber current sensor by applying the multiplex transmission technology of optical fiber current sensor signal in order to solve these subjects.

  2. Development and water requirements of cowpea under climate change conditions in the Brazilian semi-arid region

    Directory of Open Access Journals (Sweden)

    Edmilson G. Cavalcante Junior

    Full Text Available ABSTRACT This study aimed to determine the impacts that climate change may cause on the development and evapotranspiration of cowpea, in semi-arid climate region of Northeast Brazil. The study was conducted in the municipalities of Apodi, Ipanguaçu and Mossoró, in the state of Rio Grande do Norte. In order to evaluate the influence of climate change on crop water consumption, changes in air temperature and relative humidity were simulated using the PRECIS climate model. Two scenarios of emissions were evaluated based on the report of the Intergovernmental Panel on Climate Change: a pessimistic named A2 and an optimistic B2. The duration of the crop cycle showed an average reduction of 14 and 23 days for the optimistic and pessimistic scenarios, respectively. Temperatures will be well above the limit tolerated by crop, which could have a negative impact on its development and yield. There will be a decrease in total evapotranspiration of 4.8%, considering the optimistic scenario, and 8.7% in the pessimistic scenario.

    Bipolar disorders are often not recognized and undertreated. The diagnosis of current or past episodes of hypomania is of importance in order to increase diagnostic certainty. The Hypomania Checklist-32 is a self-applied questionnaire aimed at recognizing these episodes. As part of the international collaborative effort to develop multi-lingual versions of the Hypomania Checklist-32, we aimed to validate the Brazilian version and to compare its psychometric properties with those of the Mood Disorder Questionnaire. Adult outpatients with bipolar disorder I (n=37), bipolar disorder II (n=44) and major depressive disorder (n=42) of a specialized mood disorder unit were diagnosed according to DSM-IV-TR using a modified version of the SCID. We analyzed the internal consistency and discriminative ability of the Hypomania Checklist-32 Brazilian version in relation to the Mood Disorder Questionnaire. The internal consistency of the Brazilian Hypomania Checklist-32, analyzed using Cronbach's alpha coefficient, was 0.86. A score of 18 or higher in the Hypomania Checklist-32 Brazilian version distinguished between bipolar disorder and major depressive disorder, with a sensitivity of 0.75 and a specificity of 0.58, compared to 0.70 and 0.58, respectively, for the Mood Disorder Questionnaire (score>7). The Hypomania Checklist-32 Brazilian version showed a dual factor structure characterized by "active/elated" and "risk-taking/irritable" items. Hence, the Hypomania Checklist-32 Brazilian version was found to have a higher sensitivity but the same specificity as the Mood Disorder Questionnaire. The Brazilian version of the Hypomania Checklist-32 has adequate psychometric properties and helps discriminating bipolar disorder from major depressive disorder (but not bipolar disorder I from bipolar disorder II) with good sensitivity and specificity indices, similar to those of the Mood Disorder Questionnaire.

    Full Text Available Melampus coffeus belongs to a primitive group of pulmonate mollusks found mainly in the upper levels of the marine intertidal zone. They are common in the neotropical mangroves. Little is known about the biology of this species, particularly about its reproduction. The aim of this study was to 1 characterize the morphology and histology of M. coffeus' gonad; 2 describe the main gametogenesis events and link them to a range of maturity stages; 3 chronologically evaluate the frequency of the different maturity stages and their relation to environmental factors such as water, air and sediment temperatures, relative humidity, salinity and rainfall; and 4 characterize M. coffeus' spawning, eggs and newly hatched veliger larvae. Samples were collected monthly between February, 2007 and January, 2009 from the mangroves of Praia de Arpoeiras, Acaraú County, State of Ceará, northeastern Brazil. The characterization of the gonad development stages was carried out using routine histological techniques. The results of this study show that Melampus coffeus is a simultaneous hermaphrodite. The follicles have masculine and feminine elements, interleaved within the gonad. M. coffeus presents a well-defined synchronous reproductive cycle, showing successive maturation, release and resting periods. The average diameter of the oocytes was negatively correlated with salinity and positively correlated with rainfall. The results show that no reproductive activity occurs during periods of drought. After the dry season, the increasing rainfall levels and reduced salinity lead to the appearance of very dense populations, predominantly composed of small individuals.

    Full Text Available The present research seeks to understand to what extent companies in emerging countries, specifically, Brazilian, adopt dominant management practices, the so-called Euro-American practices, possess their one, or show a syncretism between the two. Methods: Mixed research. One phase was to collect data using a survey about cultural dimensions adopted from GLOBE (House 1998 management practices and also from Brazilian academy. Another was to collect data through interviews, which were analyzed in parallel. Results: Of the seven dominant cultural dimensions, indigenous practices influenced two. Another three were influenced by dominant management practices. Two of the local dimensions, even with internationalization, merged practices with Brazilian cultural traits. Even so, the practices derived from Jeitinho diminished relative to the international relations and experience of managers. Conclusions: The paper shows the existence of powerful Brazilian Indigenous Managerial Practices such as personalism and formalism. These practices have great influence on international business negotiations. On the other hand, it also shows that there are still dominant managerial practices specially in the case of more internationalized Brazilian managers

    To provide a quantitative profile of the indications and use of stereotactic body radiotherapy (SBRT) in a developing country oncology-based institution. In addition, to describe the patients' and treatment characteristics, and to provide a temporal analysis. SBRT patients treated from 2007 to 2015 were retrospectively evaluated by two independently investigators. Data were stratified and compared in two periods: first experience (FE) (May 2007 to April 2011), and following experience (FollowE) (May 2011 to April 2015). The following parameters were compared between the groups: total number of treated patients and lesions, treatment site, additional image fusion used, formal protocol adoption, and SBRT planning technique. One hundred and seventy-six (176) patients with 191 lesions were treated: 34 (18%) lesions in the FE and 157 (82%) lesions in FollowE. The majority of lesions were metastases (60.3%), and lung (60.2%) was the most common treatment site, followed by spine (31%), and others (8.8%). An average of 1.4 (±0.6) additional imaging exams for delineation was performed. Conformal 3D radiotherapy planning technique was used in 64.4%, and intensity modulated radiotherapy (IMRT) or volumetric-modulated arc therapy (VMAT) in the remaining 35.6% (p=0.0001). Higher rates of curative treatments were observed in FE, as well as more lung lesions, patients ≥ 70 years, 3D conformal, number of additional images and ECOG 0, and all presented p<0.05. The global rate of protocol statement was 79%, lung treatment being the most stated. SBRT application is rapidly increasing in our setting. Treatment sites and planning techniques are becoming more diversified and complex.

    We compared sociodemographic characteristics and psychiatric status in obese Brazilian patients who did (n=32) and did not (n=33) meet DSM-IV criteria for binge-eating disorder (BED). The sample's mean age was 35.0 years (+/-10.5), with 92.3% of individuals being female and 41.5% having some higher education. Obese binge eaters (OBE) were significantly more likely than obese non-binge eaters to meet criteria for a current diagnosis of any axis I disorder, any mood disorder and any anxiety disorder. Specifically, OBE patients were characterized by significantly higher rates of current and lifetime histories of major depressive disorder. Similar to patients from developed countries, Brazilian patients with BED display increased rates of psychiatric comorbidity, particularly mood and anxiety disorders.

    Thermally stimulated current (TSC) measurement is widely used in a variety of research fields, i.e., physics, electronics, electrical engineering, chemistry, ceramics, and biology. TSC is short-circuit current that flows owing to the displacement of charges in samples during heating. TSC measurement is very simple, but TSC curves give very important information on charge behaviors. In the 1970s, TSC measurement contributed greatly to the development of electrical insulation engineering, semiconductor device technology, and so forth. Accordingly, the TSC experimental technique and its analytical method advanced. Over the past decades, many new molecules and advanced functional materials have been discovered and developed. Along with this, TSC measurement has attracted much attention in industries and academic laboratories as a way of characterizing newly discovered materials and devices. In this review, we report the latest research trend in the TSC method for the development of materials and devices in Japan.

    2010-08-01

    Full Text Available The present work describes details of the several steps of the technology involved for the orbital Gas Tungsten Arc Welding (GTAW process of pure commercially titanium tubes. These pieces will be used to connect the several components of the propulsion system of the China-Brazilian Satellite CBERS, and is part of the Brazilian aerospace industry development. The implantation involved the steps of environment control; cut and facing of the base metal; cleaning procedures; piece alignment; choice of the type, geometry and installation of the tungsten electrode; system for the pressure of the purge gas; manual tack welding; choice of the welding parameters; and, finally, the qualification of welding procedures. Three distinct welding programs were studied, using pulsed current with increasing speed, continuous current and pulsed current with decreasing amperage levels. The results showed that the high quality criteria required to the aerospace segment is such that usual welding operations must be carefully designed and executed. The three welding developed programs generated welds free of defects and with adequate morphology, allowing to select the condition that better fits the Brazilian aerospace segment, and to be implanted in the welding of the CBERS Satellite Propulsion System.

    The paper reports about the development and fabrication of a 600 A HTS current lead prototype. Main focus of this task was an economic and robust design. Thus we used a fiberglass housing, also providing electrical insulation, replaceable parts and common soldering technology. The HTS part was made from an YBCO bar fabricated according to the ATZ in-house Ceramo Crystal Growth technology. Due to mechanical reasons and to reach a sufficient low contact resistance, a bar had to be used which had a far higher transport current carrying capability than the required 600 A. The measurements at low temperatures showed, that the chosen design is suitable for application. Especially advantages for high current applications can be expected. (3 refs).

    In many industrialized countries, clinical pharmacy has developed into a separate discipline and become a vital part of inpatient care in hospitals. However, as compared to many established branches of medicine, clinical pharmacy is still in its infancy, with much room for growth, improvement, and recognition by both the medical community and patients. In this study, a widely-recognized development strategy analysis tool, Strength, Weakness, Opportunity and Threat (SWOT), was used to systematically address several key issues to the development of clinical pharmacy in China. This analysis aims to provide feasible recommendations for the development of clinical pharmacy in China by identifying current problems and growth opportunities. Full development of clinical pharmacy as a mature clinical discipline will help promote the rational use of drugs by both clinicians and patients and lead to enhanced drug efficacy and safety.

    This study examined the muscle power of Brazilian circumpubertal girls and extended the analysis to a cross-cultural dimension. A total of 462 children, 123 Brazilian girls and 339 French girls, 9-18 years, participated in this investigation. Anthropometric data included body mass (BM), height, skinfold thicknesses, and estimated lean leg volume (LLV). All subjects completed a physical activity questionnaire. Cycling peak power was measured including the flywheel inertia of the device (CPPi). Brazilian girls self-assessed their maturation using pubic hair development. CPPi and optimal velocity (v(opt) = velocity at CPPi) increased with stages of puberty. A multiple stepwise regression with anthropometric variables as explanatory factors showed only LLV and age explaining the variance of CPPi (R2 = 0.40, P CPPi in Brazilian girls was related to undetermined qualitative individual factors, which may be related to cycling skill. Even when normalized for anthropometric variables, the anaerobic performance (CPPi and v(opt)) of Brazilian girls was significantly lower than a cohort of French girls. The latter demonstrated a high participation in sport and training activities, while 50% of the Brazilian girls had only physical education classes in the form of regular physical activity. Moreover, most of the Brazilian girls demonstrated an ineffective sprint cycling skill. The data suggest that motor learning is an important issue in muscle power assessment and might, therefore, partially explain peak power differences in Brazilian compared with French girls.

    The present paper focuses on developing a numerical oil spill model that incorporates the full three-dimensional wave-current interactions for a better representation of the spilled oil transport mechanics in complicated coastal environments. The incorporation of surface wave effects is not only imposing a traditional drag coefficient formulation at the free surface, but also the 3D momentum equations are adjusted to include the impact of the vertically dependent radiation stresses on the currents. Based on the current data from SELFE and wave data from SWAN, the oil spill model utilizes oil particle method to predict the trajectory of individual droplets and the oil concentration. Compared with the observations in Dalian New Port oil spill event, the developed model taking into account wave-current coupling administers to giving better conformity than the one without. The comparisons demonstrates that 3D radiation stress impacts the spill dynamics drastically near the sea surface and along the coastline, while having less impact in deeper water.

    The term "Service robotics" describes semi- or fully autonomous technical systems able to perform services useful to the well-being of humans. Service robots have the potential to support and disburden both persons in need of care as well as nursing care staff. In addition, they can be used in prevention and rehabilitation in order to reduce or avoid the need for help. Products currently available to support people in domestic environments are mainly cleaning or remote-controlled communication robots. Examples of current research activities are the (further) development of mobile robots as advanced communication assistants or the development of (semi) autonomous manipulation aids and multifunctional household assistants. Transport robots are commonly used in many hospitals. In nursing care facilities, the first evaluations have already been made. So-called emotional robots are now sold as products and can be used for therapeutic, occupational, or entertainment activities.

    Malaria remains a global public health threat, with half of the world's population at risk. Despite numerous efforts in the past decade to develop new antimalarial drugs to surmount increasing resistance to common therapies, challenges remain in the expansion of the current antimalarial arsenal for the elimination of this disease. The requirement of prophylactic and radical cure activities for the next generation of antimalarial drugs demands that new research models be developed to support the investigation of the elusive liver stage of the malaria parasite. In this Review, we revisit current antimalarial therapies and discuss recent advances for in vitro and in vivo malaria research models of the liver stage and their importance in probing parasite biology and the discovery of novel drug candidates.

  10. The current status and trend of clinical pharmacology in developing countries

    Science.gov (United States)

    2013-01-01

    Background Several international forums for promoting clinical pharmacology in developing countries have been held since 1980, and several clinical pharmacology programmes targeting developing countries were instituted such that the status of clinical pharmacology in developing countries is not where it was 50 years ago. Therefore, a survey and an appraisal of the literature on the current status of clinical pharmacology in developing countries were undertaken with a hope that it would enable development of appropriate strategies for further promotion of clinical pharmacology in these countries. Methods First, nine determinants (or enabling factors) for running a successful clinical pharmacology programme were identified, i.e., disease burden, drug situation, economic growth, clinical pharmacology activities, recognition, human capital, government support, international collaboration, and support for traditional/alternative medicines. These factors were then evaluated with regard to their current status in the developing countries that responded to an electronic questionnaire, and their historical perspective, using the literature appraisal. From these, a projected trend was constructed with recommendations on the way forward. Results Clinical pharmacology services, research and teaching in developing countries have improved over the past 50 years with over 90% of countries having the appropriate policies for regulation and rational use of medicines in place. Unfortunately, policy implementation remains a challenge, owing to a worsening disease burden and drug situation, versus fewer clinical pharmacologists and other competing priorities for the national budgets. This has led to a preference for training ‘a physician clinical pharmacologist’ in programmes emphasizing local relevancy and for a shorter time, and the training of other professionals in therapeutics for endemic diseases (task shifting), as the most promising strategies of ensuring rational use of

    To describe the profile and the scientific output of physical therapists researchers holding a research productivity fellowship (PQ) from the Brazilian National Council of Scientific and Technological Development (Conselho Nacional de Desenvolvimento Científico e Tecnológico-CNPq). This is a cross-sectional study, which has evaluated the Lattes Curriculum of all PQ physiotherapy researchers registered at CNPq holding a research productivity fellowship in the period of 2010. The variables analyzed were: gender, geographic and institutional distribution, duration since doctorate defense, research productivity fellowship level, scientific output until 2010 and the H index in Scopus(®) and ISI databases. A total of 55 PQ from the CNPq were identified in the area of knowledge of Physical Therapy and Occupational Therapy, being 81.8% from the Southeast region of Brazil. They were predominantly female (61.8%), with research productivity fellowship level PQ2 (74.5%), and with average time since doctorate defense of 10.1 (±4.1) years. A total of 2.381 articles were published, with average of 42.5 (±18.9) articles/researcher. The average of articles published after doctorate defense was 39.40 (±18.9) articles/researchers with a mean output of 4.2 (±2.0) articles/year. We found 304 articles indexed in the Scopus(®) database with 2.463 citations, and 222 articles indexed in the Web of Science with 1.805 citations. The articles were published in 481 journals, being 244 (50.7%) of them listed on JCR-web. The researchers presented a median 5 of the H index in the Scopus(®) database, and a median 3 in ISI. The scientific output of the researchers with research productivity fellowship in the field of physical therapy stands out in their indicators, since the figures are very promising for a relatively young area and as it can be observed by the amount of published articles and citations obtained by the national and international research community.

    to describe the current state of midwifery and explore the development of midwifery research during the last two decades in four non-English speaking European countries in order to understand what factors influenced the course of establishing research as a professional activity. qualitative collective case study. Germany, Austria, Switzerland and the Netherlands. with the ICM Workshop in Germany in 1989 as a central starting point for midwifery research in all four countries, different courses, in timing as well as content, characterised its development in the individual countries. Major factors contributing to this development during the last decades involved the history and character of midwifery, initiatives of individual midwifery researchers, alliances with other professions and the transition of midwifery programmes into higher education. Whereas midwifery research is currently established as a professional role in all countries, future challenges involve the creation of its own profile and identity, while building up its own academic workforce and strengthening the role of midwifery in multidisciplinary alliances. although a common vision was shared between the four countries in 1989, midwifery research developed as a context-specific phenomenon related to the character of midwifery and education in each country. These factors have to be taken into account in the further development of midwifery as an academic discipline at a national as well as at an international level. Copyright © 2012 Elsevier Ltd.

    Over the last 120 years, the extensive advances in medical imaging allowed enhanced diagnosis and therapy of many diseases and thereby improved the quality of life of many patient generations. From the beginning, all technical solutions and imaging procedures were combined with dedicated pharmaceutical developments of contrast media, to further enhance the visualization of morphology and physiology. This symbiosis of imaging hardware and contrast media development was of high importance for the development of modern clinical radiology. Today, all available clinically approved contrast media fulfill the highest requirements for clinical safety and efficacy. All new concepts to increase the efficacy of contrast media have also to consider the high clinical safety standards and cost of goods of current marketed contrast media. Nevertheless, diagnostic imaging will contribute significantly to the progresses in medicine, and new contrast media developments are mandatory to address the medical needs of the future.

    2016-01-01

    Full Text Available Prospects for space robotics concern both the development of used prototypes to extend the capabilities and the creation of new classes of systems, the operating analogues of which are, currently, unavailable. Thus, a uniqueness of the objects of space robotics, extreme operating conditions, difficulty in full-scale ground work and tests define a variety of design solutions and a wide scope of issues for further theoretical and experimental studies. The paper highlights the tasks successfully solved up to date, involving the space robotics equipment that was used in orbital environment, those of currently solved, involving the robotics equipment that is in use, and the long-term objectives, following from the logic of the space technology development to define the ways of its further development and require a development and creation of new equipment of space robotics. Thus, the development trends of space robotics are largely defined by its history of development, on the one hand, and by a growing demand for the robotic service as applied to the promising objects of space technology, on the other one. The paper considers the trends of space robotics development, which are a consequence of the natural logic of its development and are determined by a demand for advanced objects of space technology in robotic servicing. Highlights the most important elements of a design concept and the creating and operating features of the multipurpose extendable space systems, including those, which have no analogues and prototypes, are rolled into one demand for automation, and associated with their creation, operation, and problems of utilization. The concept of assembly and service autonomous robotic space modules has been under consideration. Within the orbital assembly procedure, the typical dynamic modes, relevant in terms of practical implementation of controlled movement are highlighted.

  2. Brazilian sandy beaches: characteristics, ecosystem services, impacts, knowledge and priorities

    Directory of Open Access Journals (Sweden)

    Antonia Cecília Zacagnini Amaral

    Full Text Available ABSTRACT Sandy beaches constitute a key ecosystem and provide socioeconomic goods and services, thereby playing an important role in the maintenance of human populations and in biodiversity conservation. Despite the ecological and social importance of these ecosytems, Brazilian sandy beaches are significantly impacted by human interference, chemical and organic pollution and tourism, as well as global climate change. These factors drive the need to better understand the environmental change and its consequences for biota. To promote the implementation of integrated studies to detect the effects of regional and global environmental change on beaches and on other benthic habitats of the Brazilian coast, Brazilian marine researchers have established The Coastal Benthic Habitats Monitoring Network (ReBentos. In order to provide input for sample planning by ReBentos, we have conducted an intensive review of the studies conducted on Brazilian beaches and summarized the current knowledge about this environment. In this paper, we present the results of this review and describe the physical, biological and socioeconomics features of Brazilian beaches. We have used these results, our personal experience and worldwide literature to identify research projects that should be prioritized in the assessment of regional and global change on Brazilian sandy beaches. We trust that this paper will provide insights for future studies and represent a significant step towards the conservation of Brazilian beaches and their biodiversity.

    The aim of the present study was to provide new spirometry reference equations in a sample of the Brazilian population for the following parameters: forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC ratio, peak of expiratory flow (PEF), forced expiratory flow at 50% (FEF50%), 75% average vital capacity (FEF25-75%), and average forced expiratory flow time (FEFT). This was a prospective study using results from chest radiographs, electrocardiograms, and questionnaires to investigate the participants' respiratory symptoms, sedentarism, and comorbidities (Charlson comorbidity index). From December 2010 to July 2014, individuals were randomly selected from various locations in the state of Rio de Janeiro. All individuals were examined by a single technician in the morning at the laboratory, and performed the spirometry with the same spirometer. Spirometry values were tabulated for the creation of three equation models: linear regression, logarithmic regression, and logarithms through a method that incorporates the lambda, median, and coefficient of variation (LMS method). Initially, 7003 individuals from both genders were contacted, and 454 were recruited. The data from the new equations were compared with one Brazilian and eight international equations, resulting in a high correlation (r>0.9). The values derived from the LMS method and linear regression were very similar (P>0.5), and both could be used to acquire the reference values for Brazilian spirometry. Data derived from the equations of this study were different from the current Brazilian equation, which could be justified by the different method used.

    2015-01-01

    Japanese encephalitis (JE) remains a public health threat in Asia. Although several vaccines have been licensed, ∼ 67,900 cases of the disease are estimated to occur annually, probably because the vaccine coverage is low. Therefore, effective antiviral drugs are required to control JE. However, no licensed anti-JE drugs are available, despite extensive efforts to develop them. We provide a general overview of JE and JE virus, including its transmission cycle, distribution, structure, replication machinery, immune evasion mechanisms and vaccines. The current situation in antiviral drug development is then reviewed and future perspectives are discussed. Although the development of effective anti-JE drugs is an urgent issue, only supportive care is currently available. Recent progress in our understanding of the viral replication machinery and immune evasion strategies has identified new targets for anti-JE drug development. To date, most candidate drugs have only been evaluated in single-drug formulations, and efficient drug delivery to the CNS has virtually not been considered. However, an effective anti-JE treatment is expected to be achieved with multiple-drug formulations and a targeted drug delivery system in the near future.

    2016-08-01

    Despite being the most common type of inflammatory arthritis, gout is often poorly managed. Except for febuxostat and pegloticase, research in new therapeutic agents for the management of hyperuricemia in gout remained insufficient for several decades. With emerging evidence of possible roles of hyperuricemia in cardiometabolic comorbidities, as well as more convincing evidence regarding poor outcomes (e.g. disability, recurrent hospital admissions) in patients with uncontrolled gout, several agents are current under development. Increasing knowledge regarding renal urate transporters has resulted in the development of new generation uricosurics such as lesinurad and arhalofenate. This review aims at discussing current therapeutic strategies for gout, as well as their limitations and the possible role of emerging agents in the chronic management of hyperuricemia in gout. Drugs in phases I and II of development will be discussed, along with new agents and therapeutic classes, such as purine nucleoside phosphorylase inhibitors and dual-action drugs. These new developments are encouraging, and will hopefully contribute to a more adequate management of hyperuricemia in gout.

    2015-01-01

    Full Text Available Osteoporotic vertebral compression fractures (OVCFs have gradually evolved into a serious health care problem globally. In order to reduce the morbidity of OVCF patients and improve their life quality, two minimally invasive surgery procedures, vertebroplasty (VP and balloon kyphoplasty (BKP, have been developed. Both VP and BKP require the injection of bone cement into the vertebrae of patients to stabilize fractured vertebra. As such, bone cement as the filling material plays an essential role in the effectiveness of these treatments. In this review article, we summarize the bone cements that are currently available in the market and those still under development. Two major categories of bone cements, nondegradable acrylic bone cements (ABCs and degradable calcium phosphate cements (CPCs, are introduced in detail. We also provide our perspectives on the future development of bone cements for VP and BKP.

    2008-09-01

    Probabilistic risk assessments (PRAs) play an increasingly important role in the regulatory framework of the U.S. nuclear power industry. The Nuclear Regulatory Commission (NRC) relies on a set of plant-specific Standardized Plant Analysis Risk (SPAR) models to provide critical risk-based input to the regulatory process. The Significance Determination Process (SDP), Management Directive 8.3 - NRC Incident Investigation Program, Accident Sequence Precursor (ASP) and Mitigating Systems Performance Index (MSPI) programs are among the regulatory initiatives that receive significant input from the SPAR models. Other uses of the SPAR models include: Screening & Resolution of Generic Safety Issues, License Amendment reviews and Notice of Enforcement Discretion (NOEDs). This paper presents the current status of SPAR model development activities, future development objectives, and issues related to the development, verification and maintenance of the SPAR models.

    2013-01-01

    Managing portfolios of development and engineering projects currently presents significant challenges to companies. This is even more the case in the management of portfolio risks, where both industry and academia currently lack a clear conceptual understanding of what portfolio risks are and what...... of interdependencies in PD project portfolios (Technology, Budget, Objectives and Requirements, Infrastructure and Equipment, Skillset and Human Resources, Process and Schedule, Supplier, Legal and Regulatory, and finally Market and Customer). Second, we investigate how risk management on the portfolio level...... influences them. The objective of this paper is two-fold: First, based on a literature review and industry focus group discussions, we introduce a new model for describing portfolio-level risks. It consists of three types of risks (escalated risks, common cause risks, and cascading risks) based on 9 types...

    Zheng, Kang H; Stroes, Erik S G

    2016-12-01

    Because human genetic studies and large clinical trials have demonstrated that HDL-cholesterol levels are not causally related to cardiovascular disease risk, attention has shifted toward the functional properties of HDL. Infusion of HDL mimetics containing apolipoprotein A-I remains a potential strategy to exploit the atheroprotective effects of HDL. Three HDL mimetic drugs are under development and currently being evaluated in clinical trials. Upon infusion, these drugs increase cholesterol efflux capacity. Although proof-of-concept studies are promising, large outcome studies are awaited. Alternatively, HDL particles may be used for targeted drug delivery in a nanomedicine approach. Finally, links between cholesterol efflux and myelopoeisis may prove to be a target for HDL infusion in the future. Clinical studies are currently ongoing to evaluate the potential of several HDL mimetic drugs. Novel nanomedicinal approaches and emerging pathophysiological insights may further expand the relevance of HDL infusion.

    2013-01-01

    An eddy current testing (ECT) system using a high sensitive anisotropic magnetoresistive (AMR) sensor was developed. In this system, a 20 turn circular coil with a diameter of 3 mm was used to produce the excitation field. A high sensitivity AMR sensor was used to measure the magnetic field produced by the induced eddy currents. A specimen made of copper alloy was prepared to simulate the combustion chamber of liquid rocket. Scanning was realized by rotating the chamber with a motor. To reduce the influence of liftoff variance during scanning, a dual frequency excitation method was used. The experimental results proved that ECT system with an AMR sensor could be used to check liquid rocket combustion chamber.

  15. Articulating current service development practices: a qualitative analysis of eleven mental health projects.

    2014-01-17

    The utilisation of good design practices in the development of complex health services is essential to improving quality. Healthcare organisations, however, are often seriously out of step with modern design thinking and practice. As a starting point to encourage the uptake of good design practices, it is important to understand the context of their intended use. This study aims to do that by articulating current health service development practices. Eleven service development projects carried out in a large mental health service were investigated through in-depth interviews with six operation managers. The critical decision method in conjunction with diagrammatic elicitation was used to capture descriptions of these projects. Stage-gate design models were then formed to visually articulate, classify and characterise different service development practices. Projects were grouped into three categories according to design process patterns: new service introduction and service integration; service improvement; service closure. Three common design stages: problem exploration, idea generation and solution evaluation - were then compared across the design process patterns. Consistent across projects were a top-down, policy-driven approach to exploration, underexploited idea generation and implementation-based evaluation. This study provides insight into where and how good design practices can contribute to the improvement of current service development practices. Specifically, the following suggestions for future service development practices are made: genuine user needs analysis for exploration; divergent thinking and innovative culture for idea generation; and fail-safe evaluation prior to implementation. Better training for managers through partnership working with design experts and researchers could be beneficial.

  16. Current Status on the Development of a Double Wall Tube Steam Generator

    2007-12-15

    A fast reactor, which uses sodium as a coolant, has a lot of merits as a next generation nuclear reactor. However, the possibility of a sodium-water reaction occurrence hinders the commercialization of this reactor. As one way to improve the reliability of a steam generator, a double-wall tube steam generator is being developed in GEN-4 program. In this report, the current state of the technical developments for a double-wall tube steam generator are reviewed and a future plan for the development of a double-wall tube steam generator is established. The current focuses of this research are an improvement of the heat transfer capability for a double-wall tube and the development of a proper leak detection method for the failure of a double-wall tube during a reactor operation. The ideal goal is an on-line leak detection of a double wall tube to prevent the sodium-water reaction. However, such a method is not developed as yet. An alternative method is being used to improve the reliability of a steam generator by performing a non-destructive test of a double wall tube during the refueling period of a reactor. In this method a straight double wall tube is employed to perform this test easily, but has a difficulty regarding an absorption of a thermal expansion of the used materials. If an on-line leak detection method is developed, the demerits of a straight double-wall tube are avoided by using a helical type double-wall tube, and the probability of a sodium-water reaction can be reduced to a level less than the design-based accident.

  17. Development of a high average current polarized electron source with long cathode operational lifetime

    Directory of Open Access Journals (Sweden)

    C. K. Sinclair

    2007-02-01

    Full Text Available Substantially more than half of the electromagnetic nuclear physics experiments conducted at the Continuous Electron Beam Accelerator Facility of the Thomas Jefferson National Accelerator Facility (Jefferson Laboratory require highly polarized electron beams, often at high average current. Spin-polarized electrons are produced by photoemission from various GaAs-based semiconductor photocathodes, using circularly polarized laser light with photon energy slightly larger than the semiconductor band gap. The photocathodes are prepared by activation of the clean semiconductor surface to negative electron affinity using cesium and oxidation. Historically, in many laboratories worldwide, these photocathodes have had short operational lifetimes at high average current, and have often deteriorated fairly quickly in ultrahigh vacuum even without electron beam delivery. At Jefferson Lab, we have developed a polarized electron source in which the photocathodes degrade exceptionally slowly without electron emission, and in which ion back bombardment is the predominant mechanism limiting the operational lifetime of the cathodes during electron emission. We have reproducibly obtained cathode 1/e dark lifetimes over two years, and 1/e charge density and charge lifetimes during electron beam delivery of over 2×10^{5}   C/cm^{2} and 200 C, respectively. This source is able to support uninterrupted high average current polarized beam delivery to three experimental halls simultaneously for many months at a time. Many of the techniques we report here are directly applicable to the development of GaAs photoemission electron guns to deliver high average current, high brightness unpolarized beams.

    2010-08-15

    Brazilian agriculture covers about one-third of the land area and is expected to expand further. We assessed the compliance of present Brazilian agriculture with environmental legislation and identified challenges for agricultural development connected to this legislation. We found (i) minor illegal land use in protected areas under public administration, (ii) a large deficit in legal reserves and protected riparian zones on private farmland, and (iii) large areas of unprotected natural vegetation in regions experiencing agriculture expansion. Achieving full compliance with the environmental laws as they presently stand would require drastic changes in agricultural land use, where large agricultural areas are taken out of production and converted back to natural vegetation. The outcome of a full compliance with environmental legislation might not be satisfactory due to leakage, where pristine unprotected areas become converted to compensate for lost production as current agricultural areas are reconverted to protected natural vegetation. Realizing the desired protection of biodiversity and natural vegetation, while expanding agriculture to meet food and biofuel demand, may require a new approach to environmental protection. New legal and regulatory instruments and the establishment of alternative development models should be considered.

  1. The Brazilian investment in science and technology

    2001-01-01

    Full Text Available An analysis of Brazilian federal expenditures in science and technology is presented is this study. The 1990-1999 data were compiled from records provided by two federal agencies (MCT and CNPq responsible for managing most of the national budget related to these activities. The results indicate that the federal investments in Brazilian science and technology stagnated during the last decade (US$ 2.32 billion in 1990, US$ 2.39 billion in 1996, and US$ 2.36 billion in 1999. In contrast, a great increase in private investments in research was acknowledged both by industry and by the government during the same period, from US$ 2.12 to US$ 4.64 billion. However, this investment did not result in an increase in invention patents granted to residents (492 in 1990 and only 232 in 1997 or in a reduction of patent costs. Despite this unfavorable scenario, the number of graduate programs in the country has increased two-fold in the last decade and the contribution of Brazilians to the database of the Institute for Scientific Information has increased 4.7-fold from 1990 (2,725 scientific publications to 2000 (12,686 scientific publications. Unstable federal resources for science, together with the poor returns of private resources in terms of developing new technologies, may jeopardize the future of Brazilian technological development.

  2. Current practice in software development for computational neuroscience and how to improve it.

    Gewaltig, Marc-Oliver; Cannon, Robert

    2014-01-01

    Almost all research work in computational neuroscience involves software. As researchers try to understand ever more complex systems, there is a continual need for software with new capabilities. Because of the wide range of questions being investigated, new software is often developed rapidly by individuals or small groups. In these cases, it can be hard to demonstrate that the software gives the right results. Software developers are often open about the code they produce and willing to share it, but there is little appreciation among potential users of the great diversity of software development practices and end results, and how this affects the suitability of software tools for use in research projects. To help clarify these issues, we have reviewed a range of software tools and asked how the culture and practice of software development affects their validity and trustworthiness. We identified four key questions that can be used to categorize software projects and correlate them with the type of product that results. The first question addresses what is being produced. The other three concern why, how, and by whom the work is done. The answers to these questions show strong correlations with the nature of the software being produced, and its suitability for particular purposes. Based on our findings, we suggest ways in which current software development practice in computational neuroscience can be improved and propose checklists to help developers, reviewers, and scientists to assess the quality of software and whether particular pieces of software are ready for use in research.

In this article, the development of a new generation of humanized mice was discussed as well as their relevant application in HIV disease. Furthermore, current techniques employed to overcome the initial limitations of mouse model were reviewed. Highly immunodeficient mice which support cell and tissue differentiation and do not reject xenografts are indispensable for generating additional appropriate models useful in disease study, this phenomenom deserves emphases, scientific highlight and a definitive research focus. Since the early 2000s, a series of immunodeficient mice appropriate for generating humanized mice has been successively developed by introducing the IL-2Rγnull gene (e.g. NOD/SCID/γcnull and Rag2nullγcnull mice) through various genomic approaches. These mice were generated by genetically introducing human cytokine genes into NOD/SCID/γcnull and Rag2nullγcnull mouse backgrounds. The application of these techniques serves as a quick and appropriate mechanistic model for basic and therapeutic investigations of known and emerging infections.

    Full Text Available Abstract The Republic of Croatia is administratively subdivided into 20 counties and the City of Zagreb. Each county comprises many municipalities and towns. The library research and development service in the area of a county is provided by a county public library. In 2014 there were 10 mobile library services with 14 bookmobiles in nine counties and the City of Zagreb. 11 counties have not organised mobile library services yet despite the fact that many areas are still uncovered by the library services. This was the reason why in 2013 the Commission for mobile library services undertook a Research on the needs and plans of mobile library services development surveying all county public libraries. The research was focused on short term and long term development plans of a county library network with special emphasis to mobile library services. The results of the research are presented along with the data on the current state of mobile library services in 2013. The data are regularly collected by the Commission for mobile library services thus illustrating the current state of mobile library services in Croatia. The importance of mobile library services being a key element of the Croatian library system which offers access to a wide range of library services to the population is underlined.

    Full Text Available This paper presents partial outcomes of the research conducted under the cover of the project “V4 Scientific Centers for the Enhancement of Financial Literacy and Entrepreneurship Education“, International Visegrad Fund, Standard Grant No. 21410134. In this paper we focus on dissolving current gaps in entrepreneurship education and its impact on business development in Slovakia (one of participating countries. We do so by using the whole variety of research methods, including structured survey, direct observation, decomposition, implication, etc. We are dealing with the identification of the university education attributes important for the entrepreneurial competences development, followed by further insights into the specific area - university support of individual initiative and entrepreneurial thinking. To avoid the subjective dimension of research outcome, we look at it from two different points of view – students and teachers perceptions. We also use a cross-cultural approach and different cultural dimensions to identify the general perception of normal state of this attribute in the society. The last part of this paper summarizes our recommendations intending to improve the current state of university education system in the field of entrepreneurial competences development.

    2015-09-01

    Full Text Available The air transportation network in a country has a great impact on the local, national and global economy. In this paper, we analyze the air transportation network in Brazil with complex network features to better understand its characteristics. In our analysis, we built networks composed either by national or by international flights. We also consider the network when both types of flights are put together. Interesting conclusions emerge from our analysis. For instance, Viracopos Airport (Campinas City is the most central and connected airport on the national flights network. Any operational problem in this airport separates the Brazilian national network into six distinct subnetworks. Moreover, the Brazilian air transportation network exhibits small world characteristics and national connections network follows a power law distribution. Therefore, our analysis sheds light on the current Brazilian air transportation infrastructure, bringing a novel understanding that may help face the recent fast growth in the usage of the Brazilian transport network.

  10. Brazilian Air Force aircraft structural integrity program: An overview

    2009-01-01

    Full Text Available This paper presents an overview of the activities developed by the Structural Integrity Group at the Institute of Aeronautics and Space - IAE, Brazil, as well as the status of ongoing work related to the life extension program for aircraft operated by the Brazilian Air Force BAF. The first BAF-operated airplane to undergo a DTA-based life extension was the F-5 fighter, in the mid 1990s. From 1998 to 2001, BAF worked on a life extension project for the BAF AT- 26 Xavante trainer. All analysis and tests were performed at IAE. The fatigue critical locations (FCLs were presumed based upon structural design and maintenance data and also from exchange of technical information with other users of the airplane around the world. Following that work, BAF started in 2002 the extension of the operational life of the BAF T-25 “Universal”. The T-25 is the basic training airplane used by AFA - The Brazilian Air Force Academy. This airplane was also designed under the “safe-life” concept. As the T-25 fleet approached its service life limit, the Brazilian Air Force was questioning whether it could be kept in flight safely. The answer came through an extensive Damage Tolerance Analysis (DTA program, briefly described in this paper. The current work on aircraft structural integrity is being performed for the BAF F-5 E/F that underwent an avionics and weapons system upgrade. Along with the increase in weight, new configurations and mission profiles were established. Again, a DTA program was proposed to be carried out in order to establish the reliability of the upgraded F-5 fleet. As a result of all the work described, the BAF has not reported any accident due to structural failure on aircraft submitted to Damage Tolerance Analysis.

  11. Collection development and outsourcing in academic health sciences libraries: a survey of current practices.

    1999-04-01

    Academic health sciences libraries in the United States and Canada were surveyed regarding collection development trends, including their effect on approval plan and blanket order use, and use of outsourcing over the past four years. Results of the survey indicate that serials market forces, budgetary constraints, and growth in electronic resources purchasing have resulted in a decline in the acquisition of print items. As a result, approval plan use is being curtailed in many academic health sciences libraries. Although use of blanket orders is more stable, fewer than one-third of academic health sciences libraries report using them currently. The decline of print collections suggests that libraries should explore cooperative collection development of print materials to ensure access and preservation. The decline of approval plan use and the need for cooperative collection development may require additional effort for sound collection development. Libraries were also surveyed about their use of outsourcing. Some libraries reported outsourcing cataloging and shelf preparation of books, but none reported using outsourcing for resource selection. The reason given most often for outsourcing was that it resulted in cost savings. As expected, economic factors are driving both collection development and outsourcing practices.

    2011-01-21

    Over the last thirty years, the world has seen HIV circulate the globe, affecting 33 million people to date and killing 2 million people a year. The disease has affected developed and developing countries alike, and in the U.S., remains one of the top ten leading causes of death. Many regions of the world are highly impacted by this disease, including sub-Saharan Africa, South and South-East Asia, and Eastern Europe. Fortunately, multilateral, global efforts, along with successful developments in diagnostic tools and anti-retroviral drugs (ARVs) have successfully curbed the spread of HIV over the last ten years. In spite of this fact, access to HIV treatment and preventive healthcare is varying and limited in developing countries. A lack of healthcare infrastructure, financial support, and healthcare workers are some logistical factors that are responsible. HIV stigmatization, discrimination, and inadequate education pose additional social challenges that are hindering countries from advancing in HIV prevention. This review focuses on current technological tools that are used for HIV diagnosis and ongoing research that is aimed at addressing the conditions in low-resource settings. Recent developments in microfluidic applications and mobile health technologies are promising approaches to building a compact, portable, and robust device that can provide information-rich, real-time diagnoses. We also discuss the role that governments, healthcare workers, and even researchers can play in order to increase the acceptance of newly introduced devices and treatments in rural communities.

    2017-06-01

    Full Text Available The paper deals with the Italian economic development, explaining the main features and the crucial variables in the long-term transformation process. The Italian economy has been analysed taking into account the different and changing international rules in medium and long-term to understand their role on the development strategies and on the changing competitive position of the country. The comparative international analysis on selected crucial variables shows some contradictions between expectations and effective outcomes of changing institutional rules and introduced economic policies. This underlines both the emergence of unexpected trajectories and economic performances and the lasting of structural differences among European countries. The selection of consistent economic policies in Europe, then, should take into account these phenomena. The paper underlines the crucial role of long-term economic analysis to fully understand not only the crucial structural variables but even opportunities and challenges for strategic decisions in the current economic crisis.

    The early effectiveness of combinatorial antiretroviral therapy (cART) in the treatment of HIV infection has been compromised to some extent by rapid development of multidrug-resistant HIV strains, poor bioavailability, and cumulative toxicities, and so there is a need for alternative strategies of antiretroviral drug discovery and additional therapeutic agents with novel action modes or targets. From this perspective, we first review current strategies of antiretroviral drug discovery and optimization, with the aid of selected examples from the recent literature. We highlight the development of phosphate ester-based prodrugs as a means to improve the aqueous solubility of HIV inhibitors, and the introduction of the substrate envelope hypothesis as a new approach for overcoming HIV drug resistance. Finally, we discuss future directions for research, including opportunities for exploitation of novel antiretroviral targets, and the strategy of activation of latent HIV reservoirs as a means to eradicate the virus.

    This manuscript summarized current developments on continuous hydrogen production technologies researched in Korea advanced institute of science and technology (KAIST). Long-term continuous pilot-scale operation of hydrogen producing processes fed with non-sterile food waste exhibited successful results. Experimental findings obtained by the optimization processes of growth environments for hydrogen producing bacteria, the development of high-rate hydrogen producing strategies, and the feasibility tests for real field application could contribute to the progress of fermentative hydrogen production technologies. Three major technologies such as controlling dilution rate depending on the progress of acidogenesis, maintaining solid retention time independently from hydraulic retention time, and decreasing hydrogen partial pressure by carbon dioxide sparging could enhance hydrogen production using anaerobic leaching beds reactors and anaerobic sequencing batch reactors. These findings could contribute to stable, reliable and effective performances of pilot-scale reactors treating organic wastes.

    Full Text Available Consumer cooperatives is a partner of the state in solving social problems, it produces a variety of consumer products and services to the population. The competitiveness of various industries is estimated by the degree of demand for consumer products. Purpose of the study was to examine the industry – one of the main sectors of activity of consumer cooperatives Centrosoyuz, indicators that characterize its current state, and through the comparison of the dynamics, structure of production – to identify ways of further development of an efficient and competitive in the long term. The study methods were used: a comparison, in the abstract, logical, monographic, Economics and Statistics. Cooperative industry not only carries out the processing of agricultural raw materials purchased from the population and agricultural enterprises of different ownership forms, but also a source of commodity resources for caterers and retailers. In the industry of consumer cooperatives retained the structure of production, characteristic of the Soviet period still and hardly takes into account the current trends in the market: not only produced new products, slowing the renewal of production assets. Studies have shown that improving the efficiency of the industry is possible with a full utilization of production capacity with the introduction of advanced technologies. Under such conditions, industry consumer cooperatives to fully perform the task of providing the population with high-quality semi-finished products and processed agricultural products. Results can then be used to develop long-term programs of development of consumer cooperation. Conclusions and recommendations will contribute to the further development and improvement of competitiveness of the industry of consumer cooperatives.

    2007-01-01

    In the Brazilian society's context of meager financial resources for health care, associated with structural features of fiscal federalism and with the current model of funding transfers for the Unified Health System's (SUS), important inequities directly impact political negotiations and the deployment of federal financing alternatives which are not directly linked to the supply and production of health care activities and services by states and municipalities. We observed that health policies, since the second half of the nineties, have developed their own mechanisms that, in the above mentioned context, tend to accommodate different interests and federative conflicts generated by structural factors and by institutional rules. However, the absence of an integrated planning program between the criteria to establish resource redistribution for financing the Unified Health System and the Brazilian Federation's fiscal sharing system, end up reinforcing certain asymmetric patterns and generating new imbalances, making the compensation of inequities difficult in public health spending at the sub-national domain.

    Full Text Available Medications are frequently used for the treatment of patients with the irritable bowel syndrome (IBS, although their actual benefit is often debated. In fact, the recent progress in our understanding of the pathophysiology of IBS, accompanied by a large number of preclinical and clinical studies of new drugs, has not been matched by a significant improvement of the armamentarium of medications available to treat IBS. The aim of this review is to outline the current challenges in drug development for IBS, taking advantage of what we have learnt through the Rome process (Rome I, Rome II and Rome III. The key questions that will be addressed are: a do we still believe in the "magic bullet", i.e. a very selective drug displaying a single receptor mechanism capable of controlling IBS symptoms? b IBS is a "functional disorder" where complex neuroimmune and brain-gut interactions occur and minimal inflammation is often documented: do we need to target gut motility, visceral sensitivity or minimal inflammation? c are there validated biomarkers (accepted by regulatory agencies for studies of sensation and motility with experimental medications in humans? d do animal models have predictive and translational value? d in the era of personalised medicine, does pharmacogenomics applied to these medications already play a role? Finally, this review will briefly outline medications currently used or in development for IBS. It is anticipated that a more focussed interaction between basic science investigators, pharmacologists and clinicians will lead to better treatment of IBS.

    Full Text Available Hydrological and pollutant fate models have long been developed for research purposes. Today, they find an application in integrated watershed management, as decision support systems (DSS. GIBSI is such a DSS designed to assist stakeholders in watershed management. It includes a watershed database coupled to a GIS and accessible through a user-friendly interface, as well as modelling tools that simulate, on a daily time step, hydrological processes such as evapotranspiration, runoff, soil erosion, agricultural pollutant transport and surface water quality. Therefore, GIBSI can be used to assess a priori the effect of management scenarios (reservoirs, land use, waste water effluents, diffuse sources of pollution that is agricultural pollution on surface hydrology and water quality. For illustration purposes, this paper presents several management-oriented applications using GIBSI on the 6680 km2 Chaudière River watershed, located near Quebec City (Canada. They include impact assessments of: (i municipal clean water program; (ii agricultural nutrient management scenarios; (iii past and future land use changes, as well as (iv determination of achievable performance standards of pesticides management practices. Current and future developments of GIBSI are also presented as these will extend current uses of this tool and make it useable and applicable by stakeholders on other watersheds. Finally, the conclusion emphasizes some of the challenges that remain for a better use of DSS in integrated watershed management.

    HIV (Human Immunodeficiency virus) causes (acquired immunodeficiency syndrome) AIDS, in which the immune system of body totally fails to develop any defense against the foreign invaders. Infection with HIV occurs by transfer of blood, semen, and breast milk. HIV/AIDS is a global problem and it results nearly 25 million deaths worldwide. Developing countries like Pakistan have issues regarding Public Health. Currently, epidemic of HIV/AIDS is established in Pakistan and there is a threat of an expanded HIV/AIDS outbreak in the country. The major reason is that population is engaging in high-risk practices, low awareness about HIV/AIDS, and treacherous blood transfusion practices. A supplementary threat to Pakistan is India because both sharing a border and India is facing a rapidly growing HIV/AIDS epidemic. Local NGOs, National and International organizations are warning that in near future Pakistan may experiences bad situation regarding HIV/AIDS.In the present article we focused current situation of surveillance of HIV/AIDS, its virology, genotype, diagnostics, high-risk groups, reasons of vulnerability in Pakistani population, and the role of different national and international organizations in this situation.

    Work was performed to develop a prototype Particle Size Analyzer (PSA) for application to coated particle fuel characterization. This system was based on a light obscuration method and targeted towards high throughput analysis. Although never matured to the point of replacing existing lower throughput optical microscopy shadowgraph methods, the system was successfully applied to automating the counting of large particle samples for increased accuracy in calculating mean particle properties based on measurements of multiparticle samples. The measurement of particle size with the PSA was compared to current shadowgraph techniques and found to result in considerably greater throughput at the cost of larger measurement uncertainty. The current algorithm used by the PSA is more sensitive to particle shape and this is a likely cause of the greater uncertainty when attempting to measure average particle diameter. The use of the PSA to measure particle shape will require further development. Particle transport through the PSA and stability of the light source/detector are key elements in the successful application of this technique. A number of system pitfalls were studied and addressed.

    Liver transplantation (LT) in children now has a 20-year survival of >80%, but the longterm outcome of these grafts remains uncertain. Serial protocol liver biopsies after transplantation from several pediatric centres have demonstrated the gradual development of unexplained graft inflammation ("idiopathic" posttransplant hepatitis; IPTH) and graft fibrosis in biopsies obtained >12 months post-LT in children with good graft function and (near) normal liver biochemistry. Although the clinical significance of these findings is uncertain, there is evidence to suggest that IPTH may be a form of rejection or chronic antibody-mediated rejection as it is associated with the presence of auto/alloantibodies; de novo Class II donor-specific HLA antibodies (DSA); previous episodes of rejection, and may improve or be prevented with increased immunosuppression. Currently, the only method of diagnosing either hepatitis or fibrosis has been by serial protocol biopsies as neither serum markers of fibrosis nor noninvasive methods to detect fibrosis such as transient elastography (TE) are sufficiently validated in children. This review will focus on the diagnosis and management of idiopathic posttransplant hepatitis and graft fibrosis, discuss current methods for detecting graft injury, and potential mechanisms for their development.

    A program to demonstrate Solvent Refined Coal (SRC) technology has been initiated by the US Department of Energy (DOE) in partnership with two industrial groups. Project management responsibility has been assigned to the Oak Ridge Operations Office (ORO) of DOE. ORO requested that the Oak Ridge National Laboratory assess current research and development (R and D) activities and develop recommendations for those activities that might contribute to successful completion of the SRC demonstration plant projects. The objectives of this final report are to discuss in detail the problem areas in SRC; to discuss the current and planned R and D investigations relevant to the problems identified; and to suggest appropriate R and D activities in support of designs for the SRC demonstration plants. Four types of R and D activities are suggested: continuation of present and planned activities; coordination of activities and results, present and proposed; extension/redirection of activities not involving major equipment purchase or modifications; and new activities. Important examples of the first type of activity include continuation of fired heater, slurry rheology, and slurry mixing studies at Ft. Lewis. Among the second type of activity, coordination of data acquisition and interpretation is recommended in the areas of heat transfer, vapor/liquid equilibria, and physical properties. Principal examples of recommendations for extension/redirection include screening studies at laboratory scale on the use of carbonaceous precoat (e.g., anthracite) infiltration, and 15- to 30-day continuous tests of the Texaco gasifier at the Texaco Montebello facility (using SRC residues).

    Curation of NASA's astromaterials sample collections is a demanding and evolving activity that supports valuable science from NASA missions for generations, long after the samples are returned to Earth. For example, NASA continues to loan hundreds of Apollo program samples to investigators every year and those samples are often analyzed using instruments that did not exist at the time of the Apollo missions themselves. The samples are curated in a manner that minimizes overall contamination, enabling clean, new high-sensitivity measurements and new science results over 40 years after their return to Earth. As our exploration of the Solar System progresses, upcoming and future NASA sample return missions will return new samples with stringent contamination control, sample environmental control, and Planetary Protection requirements. Therefore, an essential element of a healthy astromaterials curation program is a research and development (R&D) effort that characterizes and employs new technologies to maintain current collections and enable new missions - an Advanced Curation effort. JSC's Astromaterials Acquisition & Curation Office is continually performing Advanced Curation research, identifying and defining knowledge gaps about research, development, and validation/verification topics that are critical to support current and future NASA astromaterials sample collections. The following are highlighted knowledge gaps and research opportunities.

    Full Text Available The optimization of the energy generated by a MagnetoHydroDynamic (MHD channel using a superconducting magnet demands the optimization of the magnetic field of the system and of the critical points on the magnet winding. This work must include the development of a high performance superconductor wire suitable for this system. Aiming to the construction of improved performance MHD channel, it was developed a low cost superconductor wire, with the required characteristics. The wire was made using a technology compatible with the assembling steps and heat treatment conditions of the MHD superconducting magnets fabrication. It was used the internal Sn method in Nb-7.5wt%Ta tube to fabricate a 271-filament wire with a diameter of 0.81 mm and a Cu/nonCu ratio of 2.3. The wire was heat treated at 200 °C to diffuse the Sn into the Cu shell, producing bronze, followed by the final reaction at temperatures ranging from 670 °C to 730 °C during 25 to 150 h, to produce (Nb,Ta3Sn. The superconducting wire characterization was made measuring the critical current Ic versus the applied magnetic field in the range of 5 to 20 T, the critical temperature Tc and the residual resistivity ratio (RRR. The wire transported critical currents above those available in commercial superconducting wires. These values of Ic are higher than the expected values for the optimization of the MHD channel.

    Treatment of primary adrenal insufficiency (PAI) requires lifelong hormone replacement with glucocorticoids (GCs) and mineralocorticoids. Impaired quality of life and increased standardized mortality ratio in these patients emphasize the importance of tailoring therapy to individual needs. Role of education is paramount in improving patient compliance and in anticipating and preventing adrenal crises. Although discovery of synthetic GCs was a major breakthrough in treatment of patients with this life-threatening condition, management of PAI continues to be challenging. The obstacles for clinicians appear to vary widely across the globe. While optimization and individualization of therapy after diagnosis of PAI remain the main challenges for clinicians in the developed world, doctors in a developing country face problems at almost every stage from the diagnosis to the treatment and follow-up of these patients; cost of therapy, lack of resources, and funding are the main hindrances. Adherence to therapy and patient education are found to be common issues in most parts of the world. This commentary highlights the challenges from both developed and developing country's perspective in treating PAI; it also provides an update on current management scenario and future treatment options.

    Paleoceanographic reconstructions in upwelling regions can provide relevant information about changes in primary productivity, ocean-atmosphere interactions and the carbon budget. Here, we assessed new data on planktonic foraminifera from a sediment core located near to coastal upwelling zones along the Brazilian coast. Our new data was combined with previous records to reveal the state of upwelling systems along the western South Atlantic margin throughout the last two deglacial and interglacial periods sensu lato. Despite the contemporary oligotrophic scenario of the Santos Basin, a remarkably high relative abundance of Globigerina bulloides and low temperatures at a depth of 100 m indicated upwelling conditions similar to current shelf upwelling zones from 130 to 90 kyr BP. Comparing these results with previous studies, we argue that Brazilian shelf upwelling zones expanded offshore between 20 and 28°S. We develop two conceptual scenarios to characterize the system: (1) during Marine Isotopic Stage (MIS 5), the system expanded along the continental margin between 20 and 28°S following the eccentricity maximum; and (2) after 20 kyr BP, the system retracted to current continental shelf zones. We propose a new mechanism whereby variation of the Earth's eccentricity, which drives seasonality, is the main factor controlling expansion or retraction of the Brazilian upwelling system. Absence of such conditions in more recent periods supports our model and indicates that current upwelling zones are the remnants of a larger upwelling system. However, more studies are required to better define the latitudinal boundaries of the Brazilian upwelling system in the past and its possible influences over the regional carbon budget.

    Full Text Available The prevalence of obesity, pre-diabetes, and type 2 diabetes (T2D is increasing worldwide, especially in the developing nations of South America. Brazil has experienced an exponential increase in the prevalence of these chronic non-communicable diseases. The rising prevalence is probably due to changing eating patterns, sedentary living, and a progressive aging of the population. These trends and their underlying causes carry untoward consequences for all Brazilians and the future of Brazilian public health and the healthcare system. Lifestyle changes that include healthy eating (nutrition therapy and regular physical activity (structured exercise represent efficient inexpensive measures to prevent and/or treat the aforementioned disorders and are recommended for all afflicted patients. Regrettably, the implementation of lifestyle changes is fraught with clinical and personal challenges in real life. The transcultural Diabetes Nutrition Algorithm (tDNA is a therapeutic tool intended to foster implementation of lifestyle recommendations and to improve disease-related outcomes in common clinical settings. It is evidence-based and amenable to cultural adaptation. The Brazilian Diabetes Association, Society of Cardiology and Ministry of Health guidelines for nutrition therapy and physical exercise were considered for the Brazilian adaptation. The resultant tDNA-Brazil and its underlying recommendations are presented and explained.

    A bright ray that developed in the wake of a fast coronal mass ejection (CME) on 2005 September 7 presents a unique opportunity to study the early development and physical characteristics of a reconnecting current sheet (CS). Polarization brightness images from the Mk4 K-Coronameter at the Mauna Loa Solar Observatory are used to determine the structure of the ray along its axis low in the corona as it progressed outward. Coverage of the early development of the ray out to ∼1.3 R {sub ☉} for a period of ∼27 hr after the start of the event enables for the first time in white light a measurement of a CME CS from the top of the arcade to the base of the flux rope. Measured widths of the ray are combined to obtain the kinematics of the upper and lower {sup Y-}points described in reconnection flux-rope models such as that of Lin and Forbes. The time dependence of these points are used to derive values for the speed and acceleration of the growth of the CS. We note the appearance of a large structure which increases in size as it expands outward in the early development of the ray and an apparent oscillation with a period of ∼0.5 hr in the position angle of the ray.

    Diabetes mellitus is a major health problem in developing countries. There are various insulin therapies to manage diabetes mellitus. This systematic review evaluates various insulin therapies for management of diabetes mellitus worldwide. This review also focuses on recent developments being explored for better management of diabetes mellitus. We reviewed a number of published articles from 2002 to 2016 to find out the appropriate management of diabetes mellitus. The paramount parameters of the selected studies include the insulin type & its dose, type of diabetes, duration and comparison of different insulin protocols. In addition, various newly developed approaches for insulin delivery with potential output have also been evaluated. A great variability was observed in managing diabetes mellitus through insulin therapy and the important controlling factors found for this therapy include; dose titration, duration of insulin use, type of insulin used and combination therapy of different insulin. A range of research articles on current trends and recent advances in insulin has been summarized, which led us to the conclusion that multiple daily insulin injections or continuous subcutaneous insulin infusion (insulin pump) is the best method to manage diabetes mellitus. In future perspectives, development of the oral and inhalant insulin would be a tremendous breakthrough in Insulin therapy. Copyright © 2017 Diabetes India. Published by Elsevier Ltd.

    Full Text Available A content analysis of four Brazilian news media portals found that economic news dominated the top headlines with little attention paid to education, the environment and welfare. Other trends included a focus on local events and national news sources, reliance on few sources, mostly official ones, and a low percentage of news that fitted the concept of newsworthiness (a combination of both social significance and deviance concepts. Other findings of a study of 432 top news stories published by UOL, Estadão, iG and Terra during a 15-day period between February and March 2008 indicate that the top portions of the portals’ front pages carry news that lacks story depth, editorial branding, and multimedia applications. The results suggest that online news portals are in their infancy although Brazil has the largest online population of Latin America. This study hopes to shed light on the gatekeeping process in Brazilian news portals. Brazilian media portals have yet to become a significant editorial force able to provide knowledge about social issues and public affairs in a socially responsible fashione.

    New scientific articles about tuberculosis (TB) are published daily worldwide. However, it is difficult for health care workers, overloaded with work, to stay abreast of the latest research findings and to discern which information can and should be used in their daily practice on assisting TB patients. The purpose of the III Brazilian Thoracic Association (BTA) Guidelines on TB is to critically review the most recent national and international scientific information on TB, presenting an updated text with the most current and useful tools against TB to health care workers in our country. The III BTA Guidelines on TB have been developed by the BTA Committee on TB and the TB Work Group, based on the text of the II BTA Guidelines on TB (2004). We reviewed the following databases: LILACS (SciELO) and PubMed (Medline). The level of evidence of the cited articles was determined, and 24 recommendations on TB have been evaluated, discussed by all of the members of the BTA Committee on TB and of the TB Work Group, and highlighted. The first version of the present Guidelines was posted on the BTA website and was available for public consultation for three weeks. Comments and critiques were evaluated. The level of scientific evidence of each reference was evaluated before its acceptance for use in the final text.

    The integument forms a number of different types of mineralized element, including dermal denticles, scutes, ganoid scales, elasmoid scales, fin rays and osteoderms found in certain fish, reptiles, amphibians and xenarthran mammals. To this list can be added teeth, which are far more widely represented and studied than any of the other mineralized elements mentioned above, and as such can be thought of as a model mineralized system. In recent years the focus for studies on tooth development has been the mouse, with a wealth of genetic information accrued and the availability of cutting edge techniques. It is the mouse dentition that this review will concentrate on. The development of the tooth will be followed, looking at what controls the shape of the tooth and how signals from the mesenchyme and epithelium interact to lead to formation of a molar or incisor. The number of teeth generated will then be investigated, looking at how tooth germ number can be reduced or increased by apoptosis, fusion of tooth germs, creation of new tooth germs, and the generation of additional teeth from existing tooth germs. The development of mineralized tissue will then be detailed, looking at how the asymmetrical deposition of enamel is controlled in the mouse incisor. The continued importance of epithelial-mesenchymal interactions at these later stages of tooth development will also be discussed. Tooth anomalies and human disorders have been well covered by recent reviews, therefore in this paper we wish to present a classical review of current knowledge of tooth development, fitting together data from a large number of recent research papers to draw general conclusions about tooth development.

    2017-01-01

    Safety tested Modified Vaccinia virus Ankara (MVA) is licensed as third-generation vaccine against smallpox and serves as a potent vector system for development of new candidate vaccines against infectious diseases and cancer. Historically, MVA was developed by serial tissue culture passage in primary chicken cells of vaccinia virus strain Ankara, and clinically used to avoid the undesirable side effects of conventional smallpox vaccination. Adapted to growth in avian cells MVA lost the ability to replicate in mammalian hosts and lacks many of the genes orthopoxviruses use to conquer their host (cell) environment. As a biologically well-characterized mutant virus, MVA facilitates fundamental research to elucidate the functions of poxvirus host-interaction factors. As extremely safe viral vectors MVA vaccines have been found immunogenic and protective in various preclinical infection models. Multiple recombinant MVA currently undergo clinical testing for vaccination against human immunodeficiency viruses, Mycobacterium tuberculosis or Plasmodium falciparum. The versatility of the MVA vector vaccine platform is readily demonstrated by the swift development of experimental vaccines for immunization against emerging infections such as the Middle East Respiratory Syndrome. Recent advances include promising results from the clinical testing of recombinant MVA-producing antigens of highly pathogenic avian influenza virus H5N1 or Ebola virus. This review summarizes our current knowledge about MVA as a unique strain of vaccinia virus, and discusses the prospects of exploiting this virus as research tool in poxvirus biology or as safe viral vector vaccine to challenge existing and future bottlenecks in vaccinology. © 2017 Elsevier Inc.

    Full Text Available Over the last two decades, the number of studies on motor imagery in children has witnessed a large expansion. Most studies used the hand laterality judgment paradigm or the mental chronometry paradigm to examine motor imagery ability. The main objective of the current review is to collate these studies to provide a more comprehensive insight in children’s motor imagery development and its age of onset. Motor imagery is a form of motor cognition and aligns with forward (or predictive models of motor control. Studying age-related differences in motor imagery ability in children therefore provides insight in underlying processes of motor development during childhood. Another motivation for studying age-related differences in motor imagery is that in order to effectively apply motor imagery training in children (with motor impairments, it is pertinent to first establish the age at which children are actually able to perform motor imagery.Overall, performance in the imagery tasks develops between 5 and 12 years of age. The age of motor imagery onset, however, remains equivocal, as some studies indicate that children of 5 to 7 years old can already enlist motor imagery in an implicit motor imagery task, whereas other studies using explicit instructions revealed that children do not use motor imagery before the age of 10. From the findings of the current study, we can conclude that motor imagery training is potentially a feasible method for paediatric rehabilitation in children from 5 years on. We suggest that younger children are most likely to benefit from motor imagery training that is presented in an implicit way. Action observation training might be a beneficial adjunct to implicit motor imagery training. From 10 years of age, more explicit forms of motor imagery training can be effectively used.

    Full Text Available The elaboration of profile characteristics that can serve as parameters in the different categories and investment in scientific studies of Brazilian volleyball have shown their importance in developing new athletes. In this sense, the objective of the descriptive study in question was to analyze important characteristics such as somatotype and anthropometry in the Brazilian under-17 and under-18 national teams, respectively. The population was composed of 33 (14 females and 19 males athletes from the aforementioned teams. We used a high-precision scale and stadiometer to verify anthropometric characteristics and Heath & Carter’s method to evaluate somatotype. The men’s team obtained the following mean results: Age = 16.71; height = 195.9cm; body weight = 87.7kg; endomorphy = 1.26; mesomorphy = 3.18 and ectomorphy = 3.8; while the women’s results were: Age = 15.9; height = 181.6cm; body weight = 67.4kg; endomorphy = 3.09; mesomorphy = 2.21 and ectomorphy = 3.88. We can conclude from the results that the teams in question have similar characteristics to those of the high-performance adult teams, and exhibit a predominance of the ectomorphic component of the somatotype. This finding is of great importance, given the current demands of high-performance volleyball, and shows us the high level of the group studied.

    Adolescents with Asperger syndrome (AS: without delay in speech development, diagnosed according to ICD-10 clinical criteria) were compared with a group with high-functioning autism (HFA: all with delayed speech development), and a group with conduct disorder (CD). Family and genetic studies suggest that Asperger syndrome and autism form part of the same spectrum, whereas the social impairments in conduct disorder are assumed to have different origins. The aims were to explore the relationships between early speech development and other aspects of functioning in autistic disorders, and to compare autistic and nonautistic social impairments. Early and current behaviour and IQ profiles were investigated. The CD group were clearly different from both the AS and HFA groups. The AS group tended to have less severe early behavioural abnormalities than the HFA group, and were unlikely to have speech abnormalities, but other communicative, social, and restricted/ stereotyped behavioural difficulties were largely of a similar pattern to the abnormalities in the HFA group. Eighty per cent of the AS group met criteria for autism on the diagnostic algorithm associated with the Autism Diagnostic Interview-Revised. By adolescence, the AS group were reported to be as abnormal as the HFA group but in structured 1:1 interaction their conversation was better. IQ profile in the AS group showed relative strength on verbal measures, unlike the HFA group, but relatively good performance on the Block Design subtest of the WISC/WAIS was a feature of both the AS and HFA groups. The results indicate closely similar behavioural manifestations may arise by adolescence despite differences in speech development. Follow-up studies and further family investigations will be required to clarify the origins of these and other patterns of autistic development.

    The Association for Professionals in Infection Control and Epidemiology, Inc, developed its first model of infection preventionist (IP) competency in 2011. The model is based on the principles of patient safety, professional and practice standards, and core competencies identified through research conducted by the Certification Board of Infection Control and Epidemiology, Inc. In addition, the model highlights 4 domains that are predicted to be key areas for future competency development. Performance improvement (PI) and implementation represent 1 of the 4 forward-focused domains. Concurrently, the inclusion of implementation science (IS) in the competency model is consistent with the research goals established by the Association for Professionals in Infection Control and Epidemiology, Inc, in its 2020 strategic plan. This article explains the importance of PI and IS and describes their relevance to the current and future IP role development. Significant challenges such as role delineation and compression are discussed. The need for the IP to acquire new competencies at integrating, as well as differentiating, PI and IS are explored in terms of emerging issues and trends.

    In the last two decades, the educational landscape for health-care training has been seen in a new light as a result of complex social changes. Against this background, the present report offers an interim appraisal and assessment of the process of making health care more academic in view of current developments and challenges. The report begins with a short description and examination of the present training situation at a pre-academic level; several reform ideas are also presented. Following this, the report reconstructs the first phase of the academization of health care in the 1990s before the advent of the Bachelor's and Master's university degrees, which were created in the framework of the Bologna Reforms, and in which it first became possible to academicize to a limited extent certain areas of the large spectrum of health-care practices. The central part of the report is a discussion of the present situation and the newest developments in the field of academic health care within the context of the Bologna process and further changing conditions. In the conclusion, the report discusses the future prerequisites that could promote a sustainable and qualitative development of the academization of health care.

  7. Viewpoint – Swimming against the Current: Questioning Development Policy and Practice

    Directory of Open Access Journals (Sweden)

    Kurt Mørck Jensen

    2013-06-01

    Full Text Available The water world is dominated by normative policies prescribing what 'good development' is all about. It is a universe of its own where policies live their own lives and feed in and out of each other. As new buzzwords continue to be invented or reinvented, policies continue to maintain their shiny images of how water resources or water supply should be managed. There are many water professionals acting as missionaries in the service of policies but probably fewer professionals acting up against blindfolded policy promotion. It is when water policies are being implemented in the real world that the trouble starts. In spite of their well-intended mission, water policies often suffer shipwreck on the socio-economic and political realities in developing countries. Through cases from India and the Mekong, the author demonstrates what happens when normative water polices are forced out of their comfort zone and into social and political realities. Although policies are made of stubborn material they need to be questioned through continuous analytical insight into developing country realities. But undertaking critical analysis and questioning the wisdom of water policies are easier said than done. It takes a lot of effort to swim against the policy current.

    Despite many recent advances in the HIV prevention landscape, an effective vaccine remains the most promising tool to end the HIV-1 pandemic. Areas covered: This review summarizes past HIV vaccine efficacy trials and current vaccine strategies as well as new approaches about to move into first-in-human trials. Expert opinion: Despite many setbacks in early HIV vaccine efficacy trials, the success of RV144 has provided the glimmer of hope necessary to invigorate the vaccine field, and has led to the development of a large number of vaccine strategies aiming at inducing an array of different immune responses. The follow-up pox-protein trials, developed to replicate and enhance the polyfunctional antibody responses induced by the RV144 regimen, are already reaching efficacy trials, while a large body of work providing a more complete understanding of the development of broadly neutralizing antibodies is now being translated into immunogen design using several different strategies. T-cell based vaccines, fallen out of favor after Ad5-based trials showed increased infection rates in Ad5 seropositive vaccine recipients, are experiencing a comeback based in part on the promising results from non-human primate challenge studies using rhCMV-based immunogens. This diverse array of vaccine candidates may finally allow us to identify a broadly effective HIV vaccine able to contain the epidemic.

    Although the European Commission and the Member States of the European Union (EU) have promoted a number of policy initiatives to foster the Energy Services Company (ESCO) industry, a recent survey of ESCO businesses in Europe has indicated that major differences exist in the development of the ESCO business among the various countries. In some countries a large number of ESCOs have been successfully operating for a number of years, while in other countries only a few ESCOs have recently started to operate. This difference could be explained by several factors, such as different levels of support offered to ESCOs by national and regional energy authorities, local market structures and rules, and variation in the definitions, roles and activities of ESCOs. This paper reviews and analyses the development and the current status of ESCO industries in the EU and the New Accession Countries. Based on the review and the analysis, a long-term strategy to foster the development of ESCOs in Europe is formulated. The strategic actions recommended build on successful experience in Europe and are proposed with an eye to existing and planned legislative measures, such as the proposed Energy Service Directive and the deployment of the Kyoto flexible mechanisms.

  10. Use of Adult Stem Cells for Cartilage Tissue Engineering: Current Status and Future Developments

    2015-01-01

    Full Text Available Due to their low self-repair ability, cartilage defects that result from joint injury, aging, or osteoarthritis, are the most often irreversible and are a major cause of joint pain and chronic disability. So, in recent years, researchers and surgeons have been working hard to elaborate cartilage repair interventions for patients who suffer from cartilage damage. However, current methods do not perfectly restore hyaline cartilage and may lead to the apparition of fibro- or hypertrophic cartilage. In the next years, the development of new strategies using adult stem cells, in scaffolds, with supplementation of culture medium and/or culture in low oxygen tension should improve the quality of neoformed cartilage. Through these solutions, some of the latest technologies start to bring very promising results in repairing cartilage from traumatic injury or chondropathies. This review discusses the current knowledge about the use of adult stem cells in the context of cartilage tissue engineering and presents clinical trials in progress, as well as in the future, especially in the field of bioprinting stem cells.

    Due to the pressing demand for metallic ore exploration technology in China, several new technologies are being employed in the relevant exploration instruments. In addition to possessing the high resolution of the traditional transient electromagnetic method, high-efficiency measurements, and a short measurement time, the multichannel transient electromagnetic method (MTEM) technology can also sensitively determine the characteristics of a low-resistivity geologic body, without being affected by the terrain. Besides, the MTEM technology also solves the critical, existing interference problem in electrical exploration technology. This study develops a full-waveform voltage and current recording device for MTEM transmitters. After continuous acquisition and storage of the large, pseudo-random current signals emitted by the MTEM transmitter, these signals are then convoluted with the signals collected by the receiver to obtain the earth's impulse response. In this paper, the overall design of the full-waveform recording apparatus, including the hardware and upper-computer software designs, the software interface display, and the results of field test, is discussed in detail.

    Wound management covers all aspects of patient care from initial injury, treatment of infection, fluid loss, tissue regeneration, wound closure to final scar formation and remodeling. There are many wound-care products available including simple protective layers, hydrogels, metal ion-impregnated dressings and artificial skin substitutes, which facilitate surface closure. This review examines recent developments in wound dressings, biomaterials and devices. Particular attention is focused on the design and manufacture of hydrogel-based dressings, their polymeric constituents and chemical modification. Finally, topical negative pressure and hyperbaric oxygen therapy are considered. Current wound-management strategies can be expensive, time consuming and labor intensive. Progress in the multidisciplinary arena of wound care will address these issues and be of immense benefit to patients, by improving both clinical outcomes and their quality of life.

    Motor neurone disease is a neurodegenerative condition with a significant morbidity and shortened life expectancy. Hypoventilatory respiratory failure is the most common cause of death and respiratory function significantly predicts both survival and quality of life in patients with motor neurone disease. Accordingly, supporting and maintaining respiratory function is important in caring for these patients. The most significant advance in motor neurone disease care of recent years has been the domiciliary provision of non-invasive ventilation for treating respiratory failure. Neuromuscular respiratory weakness also leads to ineffective cough and retained airways secretions, predisposing to recurrent chest infections. In this review, we discuss current practice and recent developments in the respiratory management of motor neurone disease, in terms of ventilatory support and cough augmentation.

    Musculoskeletal diseases such as rheumatoid arthritis are complex multifactorial disorders that are chronic in nature and debilitating for patients. A number of drug families are available to clinicians to manage these disorders but few tests exist to target these to the most responsive patients. As a consequence, drug failure and switching to drugs with alternate modes of action is common. In parallel, a limited number of laboratory tests are available which measure biological indicators or 'biomarkers' of disease activity, autoimmune status, or joint damage. There is a growing awareness that assimilating the fields of drug selection and diagnostic tests into 'companion diagnostics' could greatly advance disease management and improve outcomes for patients. This review aims to highlight: the current applications of biomarkers in rheumatology with particular focus on companion diagnostics; developments in the fields of proteomics, genomics, microbiomics, imaging and bioinformatics and how integration of these technologies into clinical practice could support therapeutic decisions.

    2014-01-01

    Full Text Available The paper outlines the current views on mechanisms for pain development in osteoarthrosis (OA. The problem of analgesia in OA remains to be solved, which gives rise to a more careful study of the mechanisms in OA. Whether peripheral somatosensory nerve damage occurs in OA is the subject of careful investigation and dispute. The paper gives the results of studies of the neurogenic component of pain in OA patients. There is sufficient evidence for the presence of sensory anomalies accompanying pain in OA. The clinical use of questionnaires to detect neuropathic pain may assist in identifying central sensitization in patients with OA. Medicaments for the symptomatic therapy of pain are characterized.

    The present work identifies, characterizes and analyses the normative requirements for the development and implementation of quality management systems in Brazilian nuclear installations and activities. The requirements established in standards IAEA GS-R-3, IAEA GS-G-3.1, IAEA DS 349, NBR ISO 9001:2000 e CNEN-NN-1.16 are critically analyzed. A correlation matrix of the applicable standards is presented and the related topics among them are identified. The standards IAEA GS-R-3, IAEA GS-G-3.1 and IAEA DS 349 define general requirements for establishing, implementing, assessing and continually improving an integrated management system in nuclear installations and activities, in IAEA member countries. The standard NBR ISO 9001:2000 establishes general requirements for the implementation of a quality management system in all kinds of organizations. The standard CNEN NN-1.16 establishes the regulating requirements for the quality assurance systems and programs of nuclear installations, for licensing and authorization for operation of these installations in Brazil. The standard IAEA GS-R-3 that replaces the code IAEA 50-C-Q introduces the concept of 'Integrated Management System' for the nuclear area, in preference to the concepts of 'Quality Assurance' and 'Quality Management'. This new approach is aligned with the current tendency incorporating requirements of quality, safety, health, environment, security, economics and other in a unique management system. Examples of quality management systems implemented by Brazilian nuclear organizations and by nuclear organizations outside Brazil are analyzed and considered in the discussion of results. (author)

    Different types of managed aquifer recharge (MAR) schemes are widely distributed and applied on various scales and for various purposes in the European countries, but a systematic categorization and compilation of data has been missing up to now. The European MAR catalogue presented herein contains various key parameters collected from the available literature. The catalogue includes 224 currently active MAR sites found in 23 European countries. Large quantities of drinking water are produced by MAR sites in Hungary, Slovakia, the Netherlands, Germany, Finland, Poland, Switzerland and France. This inventory highlights that, for over a century, MAR has played an important role in the development of European water supply and contributes to drinking-water production substantially. This development has occurred autonomously, with "trial-and-error" within the full range of climatically and hydrogeologically diverse conditions of the European countries. For the future, MAR has the potential to facilitate optimal (re)use and storage of available water resources and to take advantage of the natural purification and low energy requirements during MAR operations. Particularly with respect to the re-use of wastewater treatment-plant effluent and stormwater, which is currently underdeveloped, the use of MAR can support the public acceptance of such water-resource efficient schemes. Particularly for the highly productive and urbanized coastal zones, where the pressure on freshwater supplies increases by growing water demand, salinization and increased agricultural needs for food production (such as along the Mediterranean and North Sea coasts), MAR is expected to be increasingly relied on in Europe.

    The present work aimed to describe the current status of IVIVC/IVIVR development in the pharmaceutical industry, focusing on the use and perception of specific approaches as well as successful and failed case studies. Two questionnaires have been distributed to 13 EFPIA partners of the Oral Biopharmaceutics Tools Initiative and to the Pharmacokinetics Working Party of the European Medicines Agency in order to capture the perspectives and experiences of industry scientists and agency members, respectively. Responses from ten companies and three European Agencies were received between May 21st 2014 and January 19th 2016. The majority of the companies acknowledged the importance of IVIVC/IVIVR throughout the drug development stages and a well-balanced rate of return on investment. However, the IVIVC/IVIVR approach seemed to be underutilized in regulatory submissions. Four of the ten companies stated to have an internal guidance related to IVIVC/IVIVR modelling, whereas three felt that an overall strategy is not necessary. Successful models mainly served to support formulation development and to provide a better mechanistic understanding. There was not yet much experience with safe-space IVIVRs as well as the use of physiologically based modelling in the field of IVIVC. At the same time, the responses from both industry and agencies indicated that there might be a need for a regulatory framework to guide the application of these novel approaches. The relevance of IVIVC/IVIVR for oral IR drug products was recognized by most of the companies. For IR formulations, relationships other than Level A correlation were more common outcomes among the provided case studies, such as multiple Level C correlation or safe-space IVIVR, which could be successfully used for requesting regulatory flexibility. Compared to the responses from industry scientists, there was a trend towards a higher appreciation of the BCS among the regulators, but a less positive attitude towards the utility

    Full Text Available The purpose of this study is to test for the sustainability of current account in 18 developed and 10 developing countries. The stability of the relationship between export (inflows and import (outflows is assessed using the tests proposed by Mohitosh Kejriwal and Pierre Perron (2010. In particular, the nature of the long-run relationship, when multiple regime shifts are identified endogenously, is analyzed using the residual-based test of the null hypothesis of cointegration with multiple breaks proposed by Kejriwal (2008. The results clearly indicate that, for all countries, (i the stability tests reject the null of coefficient stability of the long-run relationship between exports and imports; (ii the cointegration tests that correspond to the number of breaks selected reject the null of cointegration (weak form of sustainability; and (iii the strong form of sustainability hypothesis is not supported by the data for all countries in most regimes but not for 20 of 28 countries especially in the last regime (the post-2000 era. For eight countries (Canada, New Zealand, Spain, Brazil, Mexico, South Africa, Thailand, and Turkey, the findings may be perceived as a warning to creditors and policymakers unless there are policy distortions or permanent productivity shocks to the domestic economies.

    Highlights: • Waste management is a matter of great concern for small island developing states. • On average, waste generation rate in these islands amounts to 1.29 kg/capita/day. • Illegal dumping and landfilling prevail in most small island developing states. • Sustainable waste management practices, previously absent, are now emerging. • However, many challenges still hinder the implementation of these practices. - Abstract: This article reviews the current status of waste management in Small Island Developing States (SIDS) and the challenges that are faced in solid waste management. The waste generation rates of SIDS were compared within the three geographic regions namely Caribbean SIDS, Pacific SIDS and Atlantic, Indian Ocean, Mediterranean and South China (AIMS) SIDS and with countries of the Organisation for Economic Co-Operation and Development (OECD). Only Pacific SIDS had a waste generation rate less than 1 kg/capita/day. The waste generation rates for the three SIDS regions averaged 1.29 kg/capita/day while that for OECD countries was at a mean value of 1.35 kg/capita/day. The waste compositions in the different SIDS regions were almost similar owing to comparable consumption patterns while these differed to a large extent with wastes generated in OECD countries. In SIDS, the major fraction of MSW comprised of organics (44%) followed by recyclables namely paper, plastics, glass and metals (total: 43%). In contrast, MSW in OECD countries consisted mainly of recyclables (43%) followed by organics (37%). This article also reviewed the other functional elements of the waste management systems in SIDS. Several shortcomings were noted in the process of waste collection, transfer and transport namely the fact of having outdated collection vehicles and narrow roads which are inaccessible. Among the waste management practices in SIDS, waste disposal via landfilling, illegal dumping and backyard burning were favoured most of the time at the expense of

    This study had the objective of determining the content of dry extract of commercial alcoholic extracts of bee propolis through Partial Least Squares (PLS) multivariate calibration and electronic spectroscopy. The PLS model provided a good prediction of dry extract content in commercial alcoholic extracts of bee propolis in the range of 2.7 a 16.8% (m/v), presenting the advantage of being less laborious and faster than the traditional gravimetric methodology. The PLS model was optimized with outlier detection tests according to the ASTM E 1655-05. In this study it was possible to verify that a centrifugation stage is extremely important in order to avoid the presence of waxes, resulting in a more accurate model. Around 50% of the analyzed samples presented content of dry extract lower than the value established by Brazilian legislation, in most cases, the values found were different from the values claimed in the product's label.

    Full Text Available Energy demand in Malaysia is increasing over seven per cent a year, while forty per cent of the energy is supplied from conventional fossil fuel. However, a number of social barriers have mired the social acceptance of renewable energy among the users. This study investigates the current status of renewable energy, problems and future outlook of renewable energy in Malaysia. A total of 200 respondents were surveyed from Klang Valley in Malaysia. Majority of the respondents use energy to generate electricity. Although some respondents reported using solar energy, there is lack of retail availability for solar energy. The findings show that limited information on renewable energy technologies, lack of awareness, and limited private sector engagement emerged as major barriers to sustainable renewable energy development. In addition, the respondents suggest for increasing policy support from the government to make information more accessible to mass users, provide economic incentives to investors and users, and promote small-community based renewable energy projects. The study suggests that the government begin small scale projects to build awareness on renewable energy, while academically, higher learning institutions include renewable energy syllabus in their academic curriculum. The study concluded that to have sustainable renewable energy development, government’s initiative, private sector engagement and users awareness must be given priority.

    Zirconium-based (Zr-based) alloys have been widely used as materials for the key components in light water reactors (LWRs), such as fuel claddings which suffer from waterside corrosion, hydrogen uptakes and strength loss at elevated temperature, especially during accident scenarios like the lost-of-coolant accident (LOCA). For the purpose of providing a safer, nuclear leakage resistant and economically viable LWRs, three general approaches have been proposed so far to develop the accident tolerant fuel (ATF) claddings: optimization of metallurgical composition and processing of Zr-based alloys, coatings on existing Zr-based alloys and replacement of current Zr-based alloys. In this manuscript, an attempt has been made to systematically present the historic development of Zr-based cladding, including the impacts of alloying elements on the material properties. Subsequently, the research investigations on coating layer on the surface of Zr-based claddings, mainly referring coating materials and fabrication methods, have been broadly reviewed. The last section of this review provides the introduction to alternative materials (Non-Zr) to Zr-based alloys for LWRs, such as advanced steels, Mo-based, and SiC-based materials.

    The task of achieving efficient delivery of drugs that have poor bioavailability or narrow absorption windows have plagued the pharmaceutically industry for decades. Thus, much research has been dedicated to the development of novel polymeric-based gastroretentive drug delivery technologies that may optimize the bioavailability and subsequent therapeutic efficacy of such drugs. An effective approach of achieving this is through the prolongation of the gastric residence time employing several gastroretentive drug delivery mechanisms such as the use of buoyant systems, high density systems, magnetic systems, mucoadhesive systems, swelling/expanding systems, superporous hydrogels and the inclusion of gastric motility retarding agents with biocompatible polymeric materials. It is known that variations in the gastric physiology such as, gastric pH, and motility exhibit both intra-as well as inter-subject variability demonstrating a significant impact on the gastric retention time and drug delivery behavior. Nevertheless, gastroretentive drug delivery systems have shown promising results. Therefore, in this mini-review, current research and development in this field (i.e. over the last 3-5 years), the polymeric material used for the design of gastroretentive drug delivery systems and techniques employed for the pharmaceutical evaluation of gastroretentive technologies are comprehensively revealed and discussed in an assimilatory manner.

    Groundwater ecosystems constitute the largest terrestrial freshwater biome. They are dark, extremely low in energy and do not provide much space but they contain an unexpectedly high diversity of living forms showing characteristic adaptive features. The restricted accessibility along with the enormous 'invisible' heterogeneity challenged for a long time testing of scientific theories and unraveling of ecosystem functioning. Triggered by an improved interdisciplinarity, comprehensive sampling strategies and current developments in biotechnology and statistical analysis, groundwater ecology gains momentum entering a new era of research. We are only beginning to understand adaptive mechanisms, species distribution patterns and ecosystem functioning. Ninety-five percent of global liquid freshwater is stored in the terrestrial subsurface constituting a major source of water for drinking, irrigation and industrial purposes. There is an urgent need to integrate evolutionary and ecological research for developing a holistic perspective of the functional roles of biodiversity and ecosystem services and predicting global changes under alternative groundwater resource use scenarios.

    This article analyses the current situation and development of Chinese medical device testing institutes from the perspectives of the two most important functions - testing functions and medical device standardization functions. Areas Covered: The objective of the Chinese government regulations for medical device industry is to ensure the safety and effectiveness of medical devices for Chinese patients. To support the regulation system, the Chinese government has established medical device testing institutes at different levels for example, the national, provincial, and municipal levels. These testing institutes also play an important role in technical support during medical device premarket registration and post market surveillance, they are also the vital practitioners of Chinese medical device standardization. Expert Commentary: Chinese medical device testing institutes are technical departments established by government, and serve the regulatory functions of government agency. In recent years, with the rapid development of medical device industry as well as constantly increasing international and domestic medical device market, the importance of medical device testing institute is more prominent, However, there are still some problems unsolved, such as their overall capacity remains to be improved, construction of standardization is to be strengthened, etc.

    Full Text Available In recent years, various technological developments markedly improved imaging of mucosal inflammation in patients with inflammatory bowel diseases. Although technological developments such as high-definition-, chromo-, and autofluorescence-endoscopy led to a more precise and detailed assessment of mucosal inflammation during wide-field endoscopy, probe-based and stationary confocal laser microscopy enabled in vivo real-time microscopic imaging of mucosal surfaces within the gastrointestinal tract. Through the use of fluorochromes with specificity against a defined molecular target combined with endoscopic techniques that allow ultrastructural resolution, molecular imaging enables in vivo visualization of single molecules or receptors during endoscopy. Molecular imaging has therefore greatly expanded the clinical utility and applications of modern innovative endoscopy, which include the diagnosis, surveillance, and treatment of disease as well as the prediction of the therapeutic response of individual patients. Furthermore, non-invasive imaging techniques such as computed tomography, magnetic resonance imaging, scintigraphy, and ultrasound provide helpful information as supplement to invasive endoscopic procedures. In this review, we provide an overview on the current status of advanced imaging technologies for the clinical non-invasive and endoscopic evaluation of mucosal inflammation. Furthermore, the value of novel methods such as multiphoton microscopy, optoacoustics, and optical coherence tomography and their possible future implementation into clinical diagnosis and evaluation of mucosal inflammation will be discussed.

    Full Text Available The article is aimed at studying the current status and determining the main results of conducting the State financial audit by the State audit service in Ukraine, as well as developing proposals as to ways of its improvement in view of the experience of the world’s leading countries and the requirements of international standards in this sphere of relations. The main indicators and results, which characterize the status of conducting by bodies of the State Audit Service of the State financial audit on key directions, were considered. The obtained data indicate that the State financial audit is taking place in the direction corresponding to international practice. Today, however, because of a number of problems and declarative provisions related to the organization and conduct of the State financial audit, it cannot fully implement all its functional capabilities and tasks. Directions of improvement and transformation of the State financial audit have been proposed. The prospect for further research is development of a holistic mechanism for the functioning of the State financial audit, which will unite all its directions at different levels and its participants.

    Full Text Available An increasing morbidity of atopic diseases (atopic dermatitis, food allergy, asthma and allergic rhinitis documented in large cohort epidemiological studies is at least partially determined by high hygienic standards of living. Over the last 40 years, the accepted concept of pathogenesis of atopic diseases, the so-called atopic march, was proposed by Fouchard in 1973. It referred to the natural history of atopy manifestation, with a typical sequence of symptoms presented as atopic dermatitis in early childhood for subsequent development of allergic respiratory symptoms in late childhood and adolescence. New data suggests that the leading role of atopic dermatitis in atopic march might be less pronounced than previously expected, indicating coexistence rather than succession of atopic symptoms. The objective of this paper is to present the currently discussed concepts of atopic dermatitis – its pathogenesis, etiology, course and role in the development of other allergic diseases. More widely, we will present: 1. The genetic factors involved in skin barrier disruption with the leading role of loss-of-function gene for filaggrin mutation, 2. Genetic defects and epigenetic regulation of the immune system 3. Epidermal changes with physical barrier dysfunction as well as 4. Skin microbiome disturbances with Staphylococcus aureus colonization leading to abnormalities of the epidermal protective barrier.

    This study aims to present the percentages of the Brazilian population holding health insurance plans, itemized by social-demographic characteristics, based on the data of the National Health Survey carried out in 2013, and to compare this information with the administrative data of the National Supplementary Health Agency for the same year. Data from the National Health Survey, and from the Beneficiaries Information System of the National Health Agency for the year 2013, were used. The percentage of people having a health plan was described according to stratification for: all of Brazil, urban/rural, Brazilian official Regions, Brazilian States and state capitals, gender, age group, level of schooling, position in the workforce, ethnic classification, and self-assessed state of health. Results include the following: The percentage of people saying they had some health plan in Brazil was 27.9% (CI 95%: 27.1-28.8). A significant difference was found relating to level of schooling - the percentage being highest for those who stated they had complete secondary education (68.8% CI 95%: 67.2-70.4) and for those who said they were currently in work (32.5% CI 95%: 31.5-33.5). The increase in health plan coverage in the Brazilian population reflects the improvement of the suply of employment and the growth in the country's economy.

    Full Text Available The implementation of modern banking activities involves the realization of investments. Investment is a complex discussion economic category, characterized by a number of features. The types and forms of investment are manifold and can be transformed with account of the state of the economy and the level of development of industrial relations. The faster growth of the financial sector in the economy has stipulated the development of financial investment. Banks as financial and lending institutions actively make financial investments in securities. Banks’ investment in securities pursues a number of purposes which determine the selection of securities for investment and their quality. The article identified the targets of bank investments in securities and their development trends under current conditions on the basis of the analysis of the actual data for 2010–2014. Negative revaluation and the actual decrease in the value of corporate securities of Russian issuers reduce their commercial appeal. Banks refuse to speculate on the stock market in favor of the securities that ensure liquidity. Banks’ investments aim to purchasing securities from the Lombard List of the Bank of Russia in order to obtain loans and participate in the repo transactions. Thus, during the analyzed period, banks’ investments in securities transformed from systemically important assets that generate substantial profit into the mechanism that provides liquidity. It should be noted that a significant part of investment resources of Russian banks services the debt obligations of Russia’s Government. The article also identified a trend of banks’ increasing investment in the participation portfolios of subsidiaries and associated joint stock companies. The official data of the Central Bank of the Russian Federation (Bank of Russia [15], and the Federal State Statistics Service [14] were used as the information base for the study

    A great number of problem-oriented software packages (e.g., DAPHNE, ESRAY, GYROSIM, just to name a few) are used for computer-aided design (CAD) and optimization of high-power gyrotrons for fusion research (most notably for ECRH and ECCD). In them, adequate self-consistent physical models formulated in a two-dimensional space (2D) are implemented. Most of the problems encountered in recent years in the development of megawatt-class gyrotrons, however, can be attributed to physical factors and phenomena that are both non-stationary (for instance various electron beam instabilities, dynamics of the trapped particles) and inherently three-dimensional by nature (e.g., non-uniformity of the emission, misalignment of the electrodes and magnetic coils, etc.). In order to address these problems and to take into account most of the physical factors that have so far been neglected, a work on the development of a novel problem-oriented software package called GYREOSS (which stands for Gyrotron Electron-Optical System Simulation) was initiated recently. Since then, GYREOSS has evolved into a test bed for experimenting with different numerical methods, algorithms, and programming techniques for ray tracing (trajectory analysis) and particle-in-cell (PIC) simulations. In this paper, we outline the current status of GYREOSS and present both its physical model formulated in 2D and 3D and its program realization. We illustrate the capabilities of the latest version of the code, which includes a novel 3D field solver and an efficient relativistic particle pusher. Finally, we present an outlook for a further development of GYREOSS.

    Full Text Available This work focuses on the rural education. It aimed to analyze and discuss the rural education in the Brazilian educational context, indicating its character and its importance from the 1990s in the perspective of building an education aimed at human emancipation and that contradictory it is also supported and guided by neoliberal educational policies. From the studies of production on rural education was found challenges, problems, difficulties and contradictions that permeate the attempt to create a perspective of rural education. The concept of rural education was initially developed within the Movement of Landless Workers (MST and other social movements from the political pressure and demands for the state to take over public education / field took dimension of public policy. This complex situation currently directs rural schools, a critical perspective that seeks an education beyond the capital.

    The assessment of the health state in patients and changes in their health state for the purpose of diagnosis, prognosis and monitoring of treatment response plays a central role in clinical practice. Quality criteria for measurements in medicine include validity, reliability, responsiveness, interpretability, and feasibility. High-quality measurement instruments are a prerequisite for evidence-based medicine. Therefore, international outcomes research groups have developed methods for quality assurance and for the standardisation of measurement instruments. Quality indicators are instruments to measure the quality of care. Due to the increasing relevance of quality assessment for all stakeholders in healthcare and due to the political intention to draw relevant conclusions from the assessment of the quality of care, quality indicators must at least meet the same high standards that are required for clinical trial end points. However, independent researchers and clinicians do not engage in the validation and standardisation of quality indicators in Germany; currently, only the AQUA institute (as assigned by the German GBA) deals with this important issue. Current activities concerning the validation of quality indicators do not meet the requirements of evidence-based healthcare. This is a critical barrier to achieving the political goals of quality medicine. Therefore, the authors propose a multi-step, multi-professional, evidence-driven and evidence-generating consensus process on the basis of established methods of outcomes research for the advancement of quality assessment with quality indicators in Germany. All relevant stakeholders should participate in this process. Copyright © 2013. Published by Elsevier GmbH.

    We have developed a high-current hydrogen-negative ion source for a negative-ion-based NBI system in Large Helical Device (LHD). The ion source is a cesium-seeded volume-production source equipped with an external magnetic filter. An arc chamber is rectangular, the dimensions of which are 35 cm x 145 cm in cross section and 21 cm in depth. A three-grid single-stage accelerator is divided into five sections longitudinally, each of which has 154(14 x 11) apertures in an area of 25 cm x 25 cm. The ion source was tested in the negative-NBI teststand, and 25 A of the negative ion beam is incident on a beamdump 13 m downstream with an energy of 104 keV for 1 sec. Multibeamlets of 770 are focused on a focal point 13 m downstream with an averaged divergence angle of 10 mrad by the geometrical arrangement of five sections of grid and the aperture displacement technique of the grounded grid. A uniform beam in the vertical direction over 125 cm is obtained with uniform plasma production in the arc chamber by balancing individual arc currents flowing through each filament. Long-pulse beam production was performed, and 1.3 MW of the negative ion beam is incident on the beamdump for 10 sec, and the temperature rise of the cooling water is almost saturated for the extraction and the grounded grids. These results satisfy the first-step specification of the LHD-NBI system. (author)

    Full Text Available Introduction. The number, range, and diversity of events with a character of festivals have been growing in the Lublin Region over the last several years. The events are organised by various entities and institutions. Information about them is largely dispersed. No study has been conducted so far determining the spatial distribution of festivals at the regional scale, and analysing their offer in the context of possibilities of development of festival tourism. Therefore, a study in the scope was undertaken with consideration of the cultural conditionings of some of the events. Material and methods. In periods from July to December 2010 and from September to December 2013, secondary information was analysed (statistics, records, and scientific studies, and original material was collected (field inventory, interview, and diagnostic survey regarding the current condition of festival tourism in the Lublin Region. Results. The collected data on festival tourism offers suggest that the number of festivals in the Lublin Region has been continuously increasing from year to year. According to the obtained data, festivals with a duration of 3 and 5 days are dominant. The majority of festivals are held in summer months, usually on weekends. Music and interdisciplinary festivals with international, national, and regional range are prevalent. Some of them already have a history of 47 years. The analysis of the spatial distribution of the festivals subject to the inventory suggests that the majority of them are organised in the largest cities of the region, namely Lublin, Zamośæ, and Kazimierz Dolny. Conclusions. Due to the very diverse offer of festivals, and the manner of their promotion, they play an important role in the promotion of the Lublin Region. The offer, spatial distribution, and dynamics in the scope of organisation of festivals provide good perspectives for the development of festival tourism in the Lublin Region.

    This article reviews the current status of waste management in Small Island Developing States (SIDS) and the challenges that are faced in solid waste management. The waste generation rates of SIDS were compared within the three geographic regions namely Caribbean SIDS, Pacific SIDS and Atlantic, Indian Ocean, Mediterranean and South China (AIMS) SIDS and with countries of the Organisation for Economic Co-Operation and Development (OECD). Only Pacific SIDS had a waste generation rate less than 1kg/capita/day. The waste generation rates for the three SIDS regions averaged 1.29kg/capita/day while that for OECD countries was at a mean value of 1.35kg/capita/day. The waste compositions in the different SIDS regions were almost similar owing to comparable consumption patterns while these differed to a large extent with wastes generated in OECD countries. In SIDS, the major fraction of MSW comprised of organics (44%) followed by recyclables namely paper, plastics, glass and metals (total: 43%). In contrast, MSW in OECD countries consisted mainly of recyclables (43%) followed by organics (37%). This article also reviewed the other functional elements of the waste management systems in SIDS. Several shortcomings were noted in the process of waste collection, transfer and transport namely the fact of having outdated collection vehicles and narrow roads which are inaccessible. Among the waste management practices in SIDS, waste disposal via landfilling, illegal dumping and backyard burning were favoured most of the time at the expense of sustainable waste treatment technologies such as composting, anaerobic digestion and recycling.

  8. Development and application of freshwater sediment-toxicity benchmarks for currently used pesticides

    2016-01-01

    Sediment-toxicity benchmarks are needed to interpret the biological significance of currently used pesticides detected in whole sediments. Two types of freshwater sediment benchmarks for pesticides were developed using spiked-sediment bioassay (SSB) data from the literature. These benchmarks can be used to interpret sediment-toxicity data or to assess the potential toxicity of pesticides in whole sediment. The Likely Effect Benchmark (LEB) defines a pesticide concentration in whole sediment above which there is a high probability of adverse effects on benthic invertebrates, and the Threshold Effect Benchmark (TEB) defines a concentration below which adverse effects are unlikely. For compounds without available SSBs, benchmarks were estimated using equilibrium partitioning (EqP). When a sediment sample contains a pesticide mixture, benchmark quotients can be summed for all detected pesticides to produce an indicator of potential toxicity for that mixture. Benchmarks were developed for 48 pesticide compounds using SSB data and 81 compounds using the EqP approach. In an example application, data for pesticides measured in sediment from 197 streams across the United States were evaluated using these benchmarks, and compared to measured toxicity from whole-sediment toxicity tests conducted with the amphipod Hyalella azteca (28-d exposures) and the midge Chironomus dilutus (10-d exposures). Amphipod survival, weight, and biomass were significantly and inversely related to summed benchmark quotients, whereas midge survival, weight, and biomass showed no relationship to benchmarks. Samples with LEB exceedances were rare (n = 3), but all were toxic to amphipods (i.e., significantly different from control). Significant toxicity to amphipods was observed for 72% of samples exceeding one or more TEBs, compared to 18% of samples below all TEBs. Factors affecting toxicity below TEBs may include the presence of contaminants other than pesticides, physical

  9. Short-term and long-term Vadose zone monitoring: Current technologies, development, and applications

    Faybishenko, Boris

    1999-05-01

    At Hanford, Savannah River, Oak Ridge, Idaho National Engineering and Environmental Laboratory (INEEL), and other DOE sites, field vadose zone observations have shown complex water seepage and mass transport behavior in a highly heterogeneous, thick vadose zone on a variety of scales. Recent investigation showed that severe contamination of soils and groundwater by organic contaminant and nuclear waste occurred because of water seepage and contaminant transport along localized, preferential, fast flow within the heterogeneous vadose zone. However, most of the existing characterization and monitoring methods are not able to locate these localized and persistent preferential pathways associated with specific heterogeneous geologic features, such as clastic dikes, caliche layers, or fractures. In addition, changes in the chemical composition of moving and indigenous solutes, particularly sodium concentration, redox conditions, biological transformation of organic materials, and high temperature, may significantly alter water, chemicals, and bio-transformation exchange between the zones of fast flow and the rest of the media. In this paper, using the data from Hanford and INEEL sites, we will (1) present evidence that central problems of the vadose zone investigations are associated with preferential, fast flow phenomena and accelerated migration of organic and radioactive elements, (2) identify gaps in current characterization and monitoring technologies, and (3) recommend actions for the development of advanced vadose zone characterization and monitoring methods using a combination of hydrologic, geochemical, and geophysical techniques.

  10. Psychosocial factors and their role in chronic pain: A brief review of development and current status

    Directory of Open Access Journals (Sweden)

    Innes Stanley I

    2005-04-01

    Full Text Available Abstract The belief that pain is a direct result of tissue damage has dominated medical thinking since the mid 20th Century. Several schools of psychological thought proffered linear causal models to explain non-physical pain observations such as phantom limb pain and the effects of placebo interventions. Psychological research has focused on identifying those people with acute pain who are at risk of transitioning into chronic and disabling pain, in the hope of producing better outcomes. Several multicausal Cognitive Behavioural models dominate the research landscape in this area. They are gaining wider acceptance and some aspects are being integrated and implemented into a number of health care systems. The most notable of these is the concept of Yellow Flags. The research to validate the veracity of such programs has not yet been established. In this paper I seek to briefly summarize the development of psychological thought, both past and present, then review current cognitive-behavioural models and the available supporting evidence. I conclude by discussing these factors and identifying those that have been shown to be reliable predictors of chronicity and those that may hold promise for the future.

  13. Current situation, potentials and prospects for the development of organic farming in Šumadija

    Brković Duško

    2016-01-01

    Full Text Available Šumadija is rich in natural potentials which provide a good basis for the future development of organic farming, given the fact that natural resources are limited. The composition and structure of natural resources are highly suitable for organic production. The region's relatively unpolluted land, favourable climate, abundant water resources and preserved biodiversity are some of the main organic farming requirements satisfied. Organic production is not possible without ensuring at least a minimum level of preservation of natural resources in areas where organic farming is practised; on the other hand, organic production itself has a positive effect on the preservation and improvement of environmental quality in these areas. Small plots of land can be advantageous for this production, particularly in upland areas, and used specifically for organic production as the conversion period is short. They can be used for vegetable farming because the soil is uncontaminated owing to distance from roads. Positive experience indicates that potatoes, rye, oats and root vegetables can be successfully grown in these areas. Another advantage is the wealth of indigenous cultivars of apples, pears and plums which are highly resistant to pathogenic pests and environmental conditions, and hence suitable for cultivation without the use of mineral fertilisers and chemical agents. Major issues currently facing organic farming are a small-scale organic market and low prices of organic products, a low level of consumer awareness of the advantages of organic farming, suspicion and ignorance, low purchasing power, low availability of organic products through sales channels, etc.

    2016-12-01

    Bovine neosporosis is a worldwide concern due to its global distribution and great economic impact. Reproductive failure in cattle due to abortion leads to major economic losses associated with the disease. Currently, there is no treatment or vaccine available against abortion or transmission caused by Neospora caninum infection in cattle. However, vaccination is considered the best measure of control against bovine neosporosis. Several host and parasite factors can influence the dynamics of the infection in bovines. Moreover, the availability of well-defined infection models is a key factor for the evaluation of vaccine candidates. However, working with cattle is not easy due to difficult handling, facilities and costs, and therefore, 'more affordable' models could be used for screening of promising vaccines to establish proof of concept. So far, live-attenuated vaccines have shown good efficacy against exogenous transplacental transmission; however, they have relevant disadvantages and associated risks, which render inactivated or subunit vaccines the best way forward. The identification of novel potential targets and vaccines, and the application of innovative vaccine technologies in harmonized experimental animal models, will accelerate the development of an effective vaccine against bovine neosporosis. © 2016 John Wiley & Sons Ltd.

    SA508 Gr.3 Mn-Mo-Ni low alloy steels have been used for nuclear reactor pressure vessel steels up to now. Currently, the design goal of nuclear power plant is focusing at larger capacity and longer lifetime. Requirements of much bigger pressure vessels may cause critical problems in the manufacturing stage as well as for the welding stage. Application of higher strength steel may be required to overcome the technical problems. It is known that a higher strength and fracture toughness of low alloy steels such as SA508 Gr.4N low alloy steel could be achieved by increasing the Ni and Cr contents. Therefore, SA508 Gr.4N low alloy steel is very attractive as eligible RPV steel for the next generation PWR systems. In this report, we propose the possibility of SA508 Gr.4N low alloy steel for an application of next generation commercial RPV, based on the literature research result about development history of the RPV steels and SA508 specification. In addition, we have surveyed the research result of HSLA(High Strength Low Alloy steel), which has similar chemical compositions with SA508 Gr.4N, to understand the problems and the way of improvement of SA508 Gr.4N low alloy steel. And also, we have investigated eastern RPV steel(WWER-1000), which has higher Ni contents compared to western RPV steel.

    The adverse effects of dietary trans fat on biomarkers of chronic disease are well documented. Regulatory authorities in many countries have enacted legislation aimed at reducing trans fat content of their food supplies, either by requiring trans fat labeling on pre-packaged foods or by limiting the amount of trans fat in oils used for food production. Increased use by the food industry of oils with a low trans fat content necessitates reevaluation of official methods used by the food industry and regulatory agencies for the determination of total trans fat. Attenuated total reflection-Fourier-transform infrared (ATR-FTIR) spectroscopy and gas chromatography with flame ionization detection (GC-FID) are two techniques used in official methods approved by method-endorsing organizations, for example AOAC International and the American Oil Chemists' Society. Here, we review current official ATR-FTIR and GC-FID methods for determination of trans fat, with a focus on factors affecting quantification of low levels of trans fat. We include new data on method performance that have only recently become available, and provide an overview of notable recent developments in lipid analysis (e.g. IR spectroscopy procedures, ionic-liquid GC columns, and multidimensional chromatographic techniques) that have the potential to substantially improve the accuracy, sensitivity, and/or speed of trans fat determination.

    Full Text Available This paper reports the results on the impact of the current visa regime policy on tourism recovery and development in Zimbabwe. The focus was on finding out how the visa regime could impact on efforts to bring into the country more visitors following the decline in visitor inflows from 2000 to 2008. Data was collected from selected visitors from different member states which require visas to enter into the county in the period between January 2010 and July 2010.The findings shows that visa restrictions play a small part in discouraging visitors to visit Zimbabwe. The visa regime policy was designed in such a way that it was easy for passport holders from traditional markets to have relatively easy passage into Zimbabwe. It was also discovered that visa restrictions were part of international travel conditions but how to get the visa became the competitive advantage or disadvantage a destination can have compared with its competitors. Zimbabwe’s traditional markets believed that the visa was not difficult to get nor was it too expensive as to scare away visitors. However, the emerging markets such as China who are in Group C had problems getting the visa as they were required to apply for the visa before traveling to Zimbabwe.

    Full Text Available Current state and development of land degradation processes based on soil monitoring system in Slovakia is evaluated in this contribution. Soil monitoring system in Slovakia is consistently running since 1993 year in 5-years repetitions. Soil monitoring network in Slovakia is constructed using ecological principle, taking into account all main soil types and subtypes, soil organic matter, climatic regions, emission regions, polluted and non-polluted regions as well as various land use. The result of soil monitoring network is 318 sites on agricultural land in Slovakia. Soil properties are evaluated according to the main threats to soil relating to European Commission recommendation for European soil monitoring performance as follows: soil erosion and compaction, soil acidification, decline in soil organic matter and soil contamination. The most significant change has been determined in physical degradation of soils. The physical degradation was especially manifested in compacted and the eroded soils. It was determined that about 39% of agricultural land is potentially affected by soil erosion in Slovakia. In addition, slight decline in soil organic matter indicates the serious facts on evaluation and extension of soil degradation processes during the last period in Slovakia. Soil contamination is without significant change for the time being. It means the soils contaminated before soil monitoring process this unfavourable state lasts also at present.

    To present the current recommendations for breast cancer screening in Brazil, as devised by the Brazilian College of Radiology and Diagnostic Imaging, the Brazilian Breast Disease Society, and the Brazilian Federation of Gynecological and Obstetrical Associations. We analyzed scientific studies available in the Medline and Lilacs databases. In the absence of evidence, the recommendations reflected the consensus of a panel of experts. Annual mammography screening is recommended for women 40-74 years of age. Among women ≥ 75 years of age, annual mammography screening should be reserved for those with an expected survival > 7 years. Complementary ultrasound should be considered for women with dense breasts. Complementary magnetic resonance imaging is recommended for women at high risk. When available, an advanced form of mammography known as tomosynthesis can be considered as a means of screening for breast cancer.

    Objective To present the current recommendations for breast cancer screening in Brazil, as devised by the Brazilian College of Radiology and Diagnostic Imaging, the Brazilian Breast Disease Society, and the Brazilian Federation of Gynecological and Obstetrical Associations. Materials and methods We analyzed scientific studies available in the Medline and Lilacs databases. In the absence of evidence, the recommendations reflected the consensus of a panel of experts. Recommendations Annual mammography screening is recommended for women 40-74 years of age. Among women ≥ 75 years of age, annual mammography screening should be reserved for those with an expected survival > 7 years. Complementary ultrasound should be considered for women with dense breasts. Complementary magnetic resonance imaging is recommended for women at high risk. When available, an advanced form of mammography known as tomosynthesis can be considered as a means of screening for breast cancer. PMID:28894332
