    Full Text Available The rhea (Rhea americana is a South American bird of the ratite group and of the Rheiformes order. It has been exploited for economical purposes, as cattle alternative in European and South American countries. In Brazil, the State of Rio Grande do Sul is outstanding, in rhea rearing and it is in the process of implantation in the Country Northeasty Region. This work aims to describe the morphology of the blood cells in rheas. In this work ten rheas were used, regardless age and sex. Two ml of peripheral blood were collected by puncture of the brachial vein with disposable syringe. The samples here partially used to make extensions with Leishman stain. Seven types of nucleate cells have been observed through morphologic analysis on the light microscope. The erythrocyte revealed an elliptical form, with condensed nucleus of elliptical form; acidophilic cytoplasm. The thrombocyte revealed an elliptical form, with nucleus located in one of the polar regions; pale cytoplasm. As to the round-shaped leukocytes, within the granulocytes, the heterophils presented excentric, condensed, and lobulated nucleus; cytoplasm rich in fusiform salmon-colored granules. The eosinophils distinguish from the heterophils due to the round eosinophilic granules. The basophils stand out from the other granulocytes due to its large and central nucleus with round specific cytoplasmic and highly basophilic granules. Within the agranulocytes, the monocytes presented reniform nucleus, which is frequently central, with slack chromatin, with small areas of condensation; cytoplasm lightly basophilic and with vacuoles. The lymphocytes presented varies forms and sizes; large nucleus with slack chromatin with some nucleoli; scarce and basophilic cytoplasm. The cells of the peripheral blood of Rhea americana present on the light microscope morphology similar to the other birds which have already been studied.

    Full Text Available Human activities have been diminishing greater rhea Rhea americana (Linnaeus, 1758 populations throughout their natural distribution. The reintroductions of captive-born greater rheas have been tried but without success; since the individuals reintroduced were killed by predators. Captive-born animals that have been isolated from predators for many generations can lose their predator recognition abilities. To enhance the survival rates of the reintroduced animals, researchers are now using antipredator training techniques. We studied the response of 15 zoo-borne greater rheas to antipredator training. The animals were divided into three groups: two test groups and one control group. We ran 15 antipredator tests and four control testes with each group. Antipredator tests consisted of pairing a taxidermized predator model or a real predator (domestic dog with a simulation of a capture procedure. Control tests consisted of presenting the predator model (jaguar to the birds, after training but not associating it with an aversive event and recording behavioural responses. All tests were video-recorded and analysed a posteriori. Results showed that the trained rheas responded appropriately to the predators, becoming more vigilant and that there was considerable individual differences in response to antipredator training. The results demonstrated that antipredator training is effective and therefore an invaluable tool for reintroduction projects involving greater rheas. Furthermore, the methods employed in this research project should be applicable to other species of flightless birds.As atividades humanas têm diminuído as populações de emas Rhea americana (Linnaeus, 1758 por toda sua área de distribuição. Reintroduções de emas nascidas em cativeiro têm sido tentadas, mas sem sucesso, uma vez que os indivíduos reintroduzidos são mortos por predadores.

    Full Text Available The antipredator training is a powerful tool now being used to help the reintroduced animals to recognise and escape from their predators. Testing the memory capacity of the animals after antipredator training is important to evaluate if the application of the training is worthwhile. A group of 15 captive-born greater rheas was studied at Belo Horizonte Zoo. Eight birds were antipredator trained and seven birds were not. After the end of the antipredator training sessions, we run four memory tests at 40, 55, 70 and 88 days after training was completed. The memory tests consisted of showing a predator model to the rheas and recording their behavioural responses. It was measured the capacity of antipredator information storage, the influence of the group size on the behaviour of the birds and the influence of the antipredator training on the elicitation of the correct behavioural responses of the birds when confronted by a predator. The results showed that the rheas retained predator recognition for almost three months, that the group size affected the responses of the birds (more defence behaviours expressed when tested alone and that the antipredator training is essential to elicit the adequate antipredatory responses, since untrained birds behaved in a tranquil manner when confronted by a predator model. We concluded that antipredator training is worthwhile for future reintroduction programs for greater rheas, since their memory capacity is considerable.O treinamento anti-predação é uma ferramenta poderosa usada atualmente para ajudar os animais reintroduzidos a reconhecer e escapar de seus predadores. Testar a capacidade de memória dos animais após o treinamento é importante para se avaliar a validade de sua aplicação. Um grupo de 15 emas nascidas em cativeiro foi estudado no zoológico de Belo Horizonte. Oito aves foram treinadas contra predadores e sete não.

    Full Text Available One of the tools set by the European Community (EC to reduce the environmental impact of firms is EMAS Regulation (Regulation (EC No 1221/2009, setting up an Environmental Management System (EMS, which aims for a continuous improvement of environmental performances. Italy has the highest number of certified organization among all European Member States, accounting for over one thousand registrations. The paper presents the result of a survey conducted through a questionnaire about EMAS implementation and targeted to all Italian registered organizations. Of nearly 1000 organizations, over 500 answers were collected. The main goal is to understand how organizations experience the scheme, focusing on main drivers for its adoption, main difficulties encountered, and perceived benefits. In particular, survey results contribute to define a reflection on the difficulties regarding EMAS diffusion among European companies. Aspects identified as critical can lead to a contraction of registration requests, especially those formulated by SMEs, which constitute the majority of Italian companies. Moreover, perceived difficulties might affect the firms’ willingness to renew EMAS registration. Data provided by the Italian Institute for Environmental Protection and Research (ISPRA recently highlighted the increasing rate of firms who decide to withdraw from registration. This study offers interesting inputs related to main critical issues in EMAS implementation, which can be the baseline for future research on companies that abandon the certification scheme, in order to provide suggestions for the improvement of its effectiveness both for national and communitarian institutions.

    In October 1995, Doel NPP of Electrabel, Belgium opted to seek registration under the EC Eco-management and Audit Scheme (EMAS). A comprehensive environmental management system (EMS) has been introduced and implemented, encompassing all four PWRs and the supporting departments. A critical step was to seek certification from an accredited environmental auditing body against the International Standard ISO 14001. This provided the foundation for the publicly available environmental statement required by EMAS. The complications of achieving EMAS at a time when national and international standards were being re-formulated were successfully overcome and Doel NPP passed its EMAS audit in June 1997. (author)

    Rhea was imaged to a resolution of approximately 1 km/lp by the Voyager spacecraft, providing the most detailed view of any Saturnian satellite. A preliminary study of Rhea divided the northern hemisphere into population 1 cratered terrain (between 20 deg and 120 deg) and population 2 cratered terrain (between 300 deg and 360 deg). Population 1 includes craters that are 40 km and were formed before the termination of population 2 bombardment, which formed craters primarily 40 km. Several geomorphic features on Rhea are classified and interpreted including three physiographic provinces, multiringed basins, craters, megascarps, ridges and scarps, and troughs and coalescing pit chains. A generalized chronology for Rhea is constructed from an analysis of the superposition relationships among the landforms and physiographic provinces.

    Full Text Available The equine piroplasmosis caused by Theileria equi is one of the most important parasitic diseases of the equine, causing damage to animal health and economic losses. In T. equi, 2 merozoite surface proteins, equi merozoite antigen EMA-1 and EMA-2, have been identified as the most immunodominant antigens. This suggests that these antigens might be used as immunobiological tools. The EMA-1 of Theileria equi was cloned and expressed in the yeast Pichia pastoris. The transformed yeast was grown at high cell density, expressing up to 389 mg.L-1 of recombinant protein. The protein was concentrated and detected in Dot blot. The recombinant product was antigenically similar to the native protein as determined using monoclonal antibodies, and polyclonal antibodies obtained from equines naturally infected with T. equi. The immunogenicity of rEMA-1 protein was demonstrated by IFAT using sera from recombinant-protein-immunized mice using aluminum hydroxide as adjuvant. All animals vaccinated with rEMA-1 developed a high specific antibody response. This results suggest that rEMA-1expressed in P. pastoris might be a strong candidate to be used as an antigen for immune diagnostics as well as a vaccine antigen.A piroplasmose equina causada por Theileria equi é uma das mais importantes doenças parasitárias de equídeos, causando danos a saúde animal e perdas econômicas. Em T. equi, 2 proteínas de superfície de merozoítos, equi merozoite antigen EMA-1 e EMA-2, têm sido identificadas como antígenos imunodominantes. Sugerindo que estes antígenos possam ser usados como produtos imunobiológicos. O gene EMA-1 de T. equi foi clonado e expressado na levedura Pichia pastoris. As leveduras transformadas foram cultivadas a altas densidades celulares expressando 389 mg.L-1 de proteína recombinante. A proteína foi concentrada e detectada em Dot blot.

    Full Text Available Sequential banding analysis (Giemsa-C-banding-Ag NOR of chromosomes of the common rhea (Rhea americana was performed. Metaphases were obtained by peripheral blood lymphocyte culture and monolayer embryo cell culture. The diploid chromosome number was 80, different from the 2n = 82 in previous reports. Macrochromosome pairs 1, 2 and 5 were submetacentric and pair 3, subacrocentric. The 4th pair was acrocentric and all of the microchromosomes appeared to be acrocentric, with the exception of a clearly metacentric pair which was fully heterochromatic. The Z was slightly larger than the W, both being acrocentric and C-band negative. Nucleolar organizer regions were observed in the secondary constriction of a microchromosome pair. Correct identification of the NOR-bearing pair was possible only by sequential analyses, Giemsa staining followed by the Ag-NOR technique.Foram efetuadas análises seqüenciais de bandeamento cromossômico (Giemsa-banda-C-AgNOR em material da espécie Rhea americana (ema com o objetivo de identificar os cromossomos portadores de regiões organizadoras de nucléolos e confirmar o cariótipo desta espécie. As metáfases foram obtidas de culturas de leucócitos e de células de embrião. O número diplóide de cromossomos, determinado pela análise de metáfases oriundas de 19 espécimes, foi de 80 (2n = 80, NF = 95, o que difere da literatura. Os pares de macrocromossomos números 1, 2 e 5 eram submetacêntricos e o par 3 era sub-acrocêntrico, confirmado pelo bandeamento C. O par 4 era acrocêntrico, bem como todos os microcromossomos, com exceção de um metacêntrico inteiramente heterocromático. O cromossomo Z era ligeiramente maior que o W, sendo ambos acrocêntricos e banda-C negativos. A região organizadora de nucléolos foi observada na constrição secundária de um par de microcromossomos.

    Full Text Available This study was undertaken to explore gum from <em>Bombax buonopozense em>calyxes as a binding agent in formulation of immediate release dosage forms using wet granulation method. The granules were characterized to assess the flow and compression properties and when compressed, non-compendial and compendial tests were undertaken to assess the tablet properties for tablets prepared with bombax gum in comparison with those prepared with tragacanth and acacia gums. Granules prepared with bombax exhibited good flow and compressible properties with angle of repose 28.60°, Carr’s compressibility of 21.30% and Hausner’s quotient of 1.27. The tablets were hard, but did not disintegrate after one hour. Furthermore, only 52.5% of paracetamol was released after one hour. The drug release profile followed zero order kinetics. Tablets prepared with bombax gum have the potential to deliver drugs in a controlled manner over a prolonged period at a constant rate.

    Full Text Available Foi estudada a flora vascular de uma área de cerrado, situada no distrito de Emas, município de Pirassununga, Estado de São Paulo (aproximadamente, 22º02'S e 47º30'W. Entre abril de 1994 e abril de 1995, realizou-se um levantamento florístico, em que foram amostradas 358 espécies. A partir dos dados deste levantamento, estudaram-se as variações fenológicas das espécies, procurando analisá-las como estratégias adaptativas. Os componentes herbáceo-subarbustivo e arbustivoarbóreo comportaram-se de maneira distinta. As espécies arbustivo-arbóreas floresceram principalmente no início da estação chuvosa, enquanto que as herbáceo-subarbustivas produziram flores, de modo geral, apenas no final da estação úmida, após período de acúmulo de carboidratos. As espécies do componente herbáceo-subarbustivo tiveram pico de frutificação no final da estação chuvosa, qualquer que fosse a síndrome de dispersão de seus diásporos. Já as espécies do componente arbustivo-arbóreo apresentaram comportamentos distintos, conforme a síndrome de dispersão. As espécies zoocóricas frutificaram ao longo de toda estação úmida, enquanto que as anemocóricas e autocóricas produziram frutos, principalmente no início da estação seca.The vascular flora of the cerrado in Emas district, Pirassununga municipality, São Paulo State (approximately 22º02'S and 47º30'W was studied.

    Full Text Available The erythrocytic-stage surface protein, Equi Merozoite Antigen 1 (EMA-1, is a major candidate for the development of a diagnostic antigen for equine piroplasmosis. In order to establish an effective diagnostic method for practical use, the gene encoding the entire EMA-1 of Theileria equi Jaboticabal strain was cloned and expressed in Escherichia coli as a histidine-tagged protein (His6-EMA1. The expressed EMA-1 reacted with specific antibodies in Western blot and had an apparent molecular mass of 34 kDa which was largely consistent with its theoretical value. The nucleotide sequence of the EMA-1 gene of Jaboticabal strain was comparatively analyzed with other published sequences. The results indicated a high degree of homology with EMA-1 genes of all other strains isolated from various countries. The recombinant purified His6-EMA1 protein was tested in an enzyme-linked immunosorbent assay (ELISA for the detection of antibodies anti-T. equi in horses. The ELISA clearly differentiated T. equi-infected from Babesia caballi-infected horse sera or normal horse sera. Field serum samples collected from horses in the State of São Paulo, Southeastern Brazil, were examined for the diagnosis of T. equi infection by ELISA. Of 170 samples analyzed, 95.88% (163/170 were positive for T. equi infection. These results suggest that the His6-EMA1 protein expressed in E. coli could be a reliable immunodiagnostic antigen for ELISA test and that T. equi infection is a serious concern in the State of São Paulo, Brazil.A proteína de superfície eritrocitária, Antígeno 1 do Merozoíta de Theileria equi (EMA-1, é um potencial candidato para o desenvolvimento de antígenos de valor diagnóstico para a piroplasmose equina.

    2012-12-01

    Full Text Available The rhea (Rhea americana americana is an american bird belonging to Ratite's family. Studies related to its morphology are still scarce. This study aims to describe the macroscopic structures of the oropharyngeal cavity. Five heads (2 to 6 months old formalin preserved were anatomically dissected to expose the oropharynx. The oropharynx of the rhea was "bell-shaped" composed by the maxillary and mandibular rhamphotheca. The roof and floor presented two distinct regions different in colour of the mucosa. The rostral region was pale pink contrasting to grey coloured caudal region. The median longitudinal ridge extended rostrally from the apex of the choana to the tip of the beak in the roof and it is clearly more prominent and rigid than the homolog in the floor that appeared thin and stretched merely along the rostral portion of the regio interramalis. The floor was formed by the interramal region, (regio interramalis tongue and laryngeal mound containing glove-shaped glottis. This study confirmed the basic morphology of the oropharinx of the rhea. However, important morphological information not previously described is highlighted and contradictory information present in the literature is clarified.

    Full Text Available This study aimed to verify the occurrence of antibodies againstToxoplasma gondii in rheas (Rhea americana and ostriches (Struthio camelus commercially breeding in Brazil. Blood samples from 20 rheas and 46 ostriches (young and adults were serologically tested using a technique known as modified agglutination test (MAT at an initial titration of 1:16 for ostriches and 1:25 for rheas. Antibodies against T. gondii were found in 50% (10/20 of the rheas, with titers ranging from 1:25 to 1:6,400. The incidence of antibodies against T. gondii in ostriches was 17.4% (8/46 with titers ranging from 1:16 to 1:256. Birds showing titers higher than 1:200 forT. gondii were mainly the young ones. Therefore, rheas and ostriches may be parasitized by T. gondii, showing high levels of antibodies against this parasite.

  18. Morphogenesis of the rhea (Rhea americana respiratory system in different embryonic and foetal stages

    Renata P. Sousa

    Full Text Available ABSTRACT: The rhea (Rhea americana is an important wild species that has been highlighted in national and international livestock. This research aims to analyse embryo-foetal development in different phases of the respiratory system of rheas. Twenty-three embryos and foetuses were euthanized, fixed and dissected. Fragments of the respiratory system, including the nasal cavity, larynx, trachea, syrinx, bronchi and lungs, were collected and processed for studies using light and scanning electron microscopy. The nasal cavity presented cubic epithelium in the early stages of development. The larynx exhibited typical respiratory epithelium between 27 and 31 days. The trachea showed early formation of hyaline cartilage after 15 days. Syrinx in the mucous membrane of 18-day foetuses consisted of ciliated epithelium in the bronchial region. The main bronchi had ciliated epithelium with goblet cells in the syringeal region. In the lung, the parabronchial stage presented numerous parabronchi between 15 and 21 days. This study allowed the identification of normal events that occur during the development of the rhea respiratory system, an important model that has not previously been described. The information generated here will be useful for the diagnosis of pathologies that affect this organic system, aimed at improving captive production systems.

    Saturn's largest icy moon, Rhea, hosts a tenuous surface-sputtered exosphere composed primarily of molecular oxygen and carbon dioxide. In this Letter, we examine Cassini Plasma Spectrometer velocity space distributions near Rhea and confirm that Cassini detected nongyrotropic fluxes of outflowing CO2+ during both the R1 and R1.5 encounters. Accounting for this nongyrotropy, we show that these possess comparable along-track densities of ˜2 × 10-3 cm-3. Negatively charged pickup ions, also detected during R1, are surprisingly shown as consistent with mass 26 ± 3 u which we suggest are carbon-based compounds, such as CN-, C2H-, C2-, or HCO-, sputtered from carbonaceous material on the moon's surface. The negative ions are calculated to possess along-track densities of ˜5 × 10-4 cm-3 and are suggested to derive from exogenic compounds, a finding consistent with the existence of Rhea's dynamic CO2 exosphere and surprisingly low O2 sputtering yields. These pickup ions provide important context for understanding the exospheric and surface ice composition of Rhea and of other icy moons which exhibit similar characteristics.

    Since the arrival of the Cassini spacecraft at Saturn in June 2004, the Visual and Infrared Mapping Spectrometer has obtained new spectral data of the icy satellites of Saturn in the spectral range from 0.35 to 5.2 ??m. Numerous flybys were performed at Saturn's second largest satellite Rhea, providing a nearly complete coverage with pixel-ground resolutions sufficient to analyze variations of spectral properties across Rhea's surface in detail. We present an overview of the VIMS observations obtained so far, as well as the analysis of the spectral properties identified in the VIMS spectra and their variations across its surface compared with spatially highly resolved Cassini ISS images and digital elevation models. Spectral variations measured across Rhea's surface are similar to the variations observed in the VIMS observations of its neighbor Dione, implying similar processes causing or at least inducing their occurrence. Thus, magnetospheric particles and dust impacting onto the trailing hemisphere appear to be responsible for the concentration of dark rocky/organic material and minor amounts of CO 2 in the cratered terrain on the trailing hemisphere. Despite the prominent spectral signatures of Rhea's fresh impact crater Inktomi, radiation effects were identified that also affect the H 2O ice-rich cratered terrain of the leading hemisphere. The concentration of H 2O ice in the vicinity of steep tectonic scarps near 270??W and geologically fresh impact craters implies that Rhea exhibits an icy crust at least in the upper few kilometers. Despite the evidence for past tectonic events, no indications of recent endogenically powered processes could be identified in the Cassini data. ?? 2011 Elsevier Ltd. All rights reserved.

    2010-01-01

    Full Text Available Environmental Management Accounting (EMA is a system, which collects, records, evaluates and disseminates information about environmentally induced financial impacts and environmental impacts of the system itself. EMA is an important source of information for decision-making processes such as management of an organization, for EMS or environmental reporting. Identified barriers were included in the study which was conducted in three phases – in organizations espousing to Responsible Care, in selected companies with ISO 14000 and in companies with environmental management systems, validated by European EMAS. In early 2010 research was completed in the field of environmental management accounting and barriers defending the implemention of EMA to organization’s information system and the subsequent use of EMA. Primary data obtained from this study were subjected to cluster analysis and the results are presented in this scientific thesis. In practise there are many obstacles to full-fledged EMA implementation process into practice organization and its functioning. Findings of the study give answers to the question: „What barriers act as obstacles to the implementation of EMA into the practise of the organization and its functioning?“

    Full Text Available The Eco-Management and Audit Scheme (EMAS is the official Environmental Management System (EMS issued by the European Union (EU. Italy is the country where EMAS is most widespread, accounting for over 1000 registered organizations. Since entry into the force of the Regulation in 1997, the number of registrations has constantly grown until 2008, when the figures started to drop. The phenomena are due to both the decrease of the annual registration rate and the lack of renewals. According to the Italian Institute for Environmental Protection and Research (ISPRA, in recent years, an increasing number of organizations decided to withdraw from EMAS registration. The purpose of this paper is to analyze the reasons of this negative trend. The first step consisted of a literature review concerning the main barriers, difficulties, and costs incurred by EMAS-registered organizations. Subsequently, this information was integrated with data about the evolution of EMAS registrations and the results of a previous survey, which involved the entire population of registered firms. The present exploratory research highlighted economic and operational domains concerning the cancellation trends that deserve a deeper investigation, which will be conducted through a questionnaire addressed to Italian firms that did not renew the registration in the last lustrum. The intended output will allow us to identify stakeholders’ priority intervention areas in order to suggest an operative strategy to reduce EMAS cancellation rates, addressed to Member States (MS Competent Bodies.

    Full Text Available The adoption of formal environmental management systems (EMS according to EMAS (Eco-Management and Audit Scheme represents a voluntary approach that aims to increase corporate environmental performance. Though EMAS can offer several advantages for organizations, registration numbers are falling. In the hospital sector, the dissemination of EMAS is low. The question arises as to what hinders hospitals when planning, implementing, and maintaining such voluntary environmental management initiatives. The results from interviews with environmental managers in EMAS registered hospitals reveal problems such as high initial effort for creation of the required documents, or lacking knowledge and staff awareness. The barriers are presented in a model synthesizing the problems chronologically on the organizational, group, and individual level. The challenges for the adoption of EMAS as a voluntary environmental management approach in hospitals are discussed. This paper contributes by creating an understanding of the barriers organizations might face when implementing an EMS. Thus, measures to actively manage and overcome barriers can be developed by organizations, consultants, reviewers, policy makers, and researchers.

    2013-04-01

    Economically motivated adulteration (EMA) of food, also known as food fraud, is the intentional adulteration of food for financial advantage. A common form of EMA, undeclared substitution with alternative ingredients, is usually a health concern because of allergen labeling requirements. As demonstrated by the nearly 300,000 illnesses in China from melamine adulteration of infant formula, EMA also has the potential to result in serious public health consequences. Furthermore, EMA incidents reveal gaps in quality assurance testing methodologies that could be exploited for intentional harm. In contrast to foodborne disease outbreaks, EMA incidents present a particular challenge to the food industry and regulators because they are deliberate acts that are intended to evade detection. Large-scale EMA incidents have been described in the scientific literature, but smaller incidents have been documented only in media sources. We reviewed journal articles and media reports of EMA since 1980. We identified 137 unique incidents in 11 food categories: fish and seafood (24 incidents), dairy products (15), fruit juices (12), oils and fats (12), grain products (11), honey and other natural sweeteners (10), spices and extracts (8), wine and other alcoholic beverages (7), infant formula (5), plant-based proteins (5), and other food products (28). We identified common characteristics among the incidents that may help us better evaluate and reduce the risk of EMA. These characteristics reflect the ways in which existing regulatory systems or testing methodologies were inadequate for detecting EMA and how novel detection methods and other deterrence strategies can be deployed. Prevention and detection of EMA cannot depend on traditional food safety strategies. Comprehensive food protection, as outlined by the Food Safety Modernization Act, will require innovative methods for detecting EMA and for targeting crucial resources toward the riskiest food products.

    Do organizations certified under the Eco-Management and Audit Scheme (EMAS) effectively discharge their environmental accountability through their statements? Is the EMAS statement a step forward for the transparency of environmental management and the empowerment of organizational stakeholders' decision-making? Drawing from the Greek EMAS registry we apply an evaluation method for the completeness and materiality of environmental statements. While the latest version of the EMAS Regulation has introduced a set of forward-looking - yet challenging - improvements, the application of the standard should be closely examined. With this in mind, the key objective of this research note is to provide - from a descriptive standpoint - insights on the content of EMAS-based environmental accountability and a basis for future research as well as fruitful policy debate.

  9. Cassini RADAR Observations of Phoebe, Iapetus, Enceladus, and Rhea

    Operating in its scatterometry mode, the Cassini radar has obtained 2.2-cm-wavelength echo power spectra from Phoebe on the inbound and outbound legs of its flyby (subradar points at W. Long, Lat. = 245,-22 deg and 328,+27 deg), from Iapetus' leading side (66,+39 deg) and trailing side (296,+44 deg) on the inbound and outbound legs of orbit BC, from Enceladus during orbits 3 (0,0 deg) and 4 (70,-13 deg), and from Rhea during orbit 11 (64,-77 deg). Our echo spectra, obtained in the same linear (SL) polarization as transmitted, are broad, nearly featureless, and much stronger than expected if the echoes were due just to single backreflections. Rather, volume scattering from the subsurface probably is primarily responsible for the echoes. This conclusion is supported by the strong anticorrelation between our targets' radar albedos (radar cross section divided by target projected area) and disc brightness temperatures estimated from passive radiometric measurements obtained during each radar flyby. Taking advantage of the available information about the radar properties of the icy satellites of Saturn and Jupiter, especially the linear- and circular-polarization characteristics of groundbased echoes from the icy Galilean satellites (Ostro et al. 1992, J. Geophys. Res. 97, 18227-18244), we estimate our targets' 2.2-cm total-power (TP) albedos and compare them to Arecibo and Goldstone values for icy satellites at 3.5, 13, and 70 cm. Our four targets' albedos span an order of magnitude and decrease in the same order as their optical albedos: Enceladus/Rhea/Iapetus/Phoebe. This sequence most likely corresponds to increasing contamination of near-surface water ice, whose extremely low electrical loss at radio wavelengths permits the multiple scattering responsible for high radar albedos. Plausible candidates for contaminants causing variations in radar albedo include ammonia, silicates, and polar organics. Modeling of icy Galilean satellite echoes indicates that penetration

    Full Text Available The adoption of Energy Management Systems (EnMSs based on international standards has gained momentum since the ISO 50001 standard was launched in 2011. Before that, the potential to improve the energy management with Environmental Management Systems (EMSs based on ISO 14001 and EMAS was identified in the literature. However, no in-depth analysis reported in the literature has explored this claim. The need for research is now even more evident with the development of new versions of the standards for environmental management―ISO 14001:2015 and EMAS III. Since many companies that already have a certified EMSs might be uncertain whether to adopt an ISO 50001 based EnMSs, the present work aims to shed light on the contribution of ISO 14001:2015 and EMAS III to energy management. Furthermore, the work summarizes the results of an empirical exploratory study carried out in eight Spanish organizations, four with an EMS implemented and certified based on ISO 14001:2015 and four more with an EMS registered to EMAS III. The findings show that both ISO14001 and EMAS certified organizations carry out energy management practices, even though they have no formal EnMSs implemented. Implications for managers and policy makers are discussed, together with avenues for further research.

    1978-01-01

    An inversion procedure to obtain the reflectance of the central region of a satellite's disk from lunar occultation data is presented. The scheme assumes that the limb darkening of the satellite depends only on the radial distance from the center of the disk. Given this assumption, normal reflectances can be derived that are essentially independent of the limb darkening and the diameter of the satellite. The procedure has been applied to our observations of the March 1974 lunar occultation of Tethys, Dione, Rhea, Titan, and Iapetus. In the V passband we derive the following normal reflectances: Rhea (0.97 plus or minus 0.20), Titan (0.24 plus or minus 0.03), Iapetus, bright face (0.60 plus or minus 0.14). For Tethys and Dione the values derived have large uncertainties, but are consistent with our result for Rhea.

    2016-09-01

    Full Text Available In recent years a growing demand for ratite meat, including ostrich, emu, and rhea has been observed all over the world. However, consumers as well as the meat industry still have limited and scattered knowledge about this type of meat, especially in the case of emu and rhea. Thus, the aim of the present review is to provide information on technological and nutritional properties of ostrich, emu, and rhea meat, including carcass composition and yields, physicochemical characteristics, and nutritive value. Carcass yields and composition among ratites are comparable, with the exception of higher content of fat in emu. Ostrich, emu, and rhea meat is darker than beef and ratite meat acidification is closer to beef than to poultry. Ratite meat can be recognised as a dietetic product mainly because of its low level of fat, high content of polyunsaturated fatty acids (PUFA, favourable n6/n3 ratio, and high iron content in comparison with beef and chicken meat. Ratite meat is also rich in selenium, copper, vitamin B, and biologically active peptides such as creatine (emu and anserine (ostrich, and has low content of sodium (ostrich. The abundance of bioactive compounds e.g. PUFA, makes ratite meat highly susceptible to oxidation and requires research concerning elaboration of innovative, intelligent packaging system for protection of nutritional and technological properties of this meat.

    Full Text Available Abstract In Italy there are two species of <em>Apodemus> (<em>Sylvaemus>: <em>Apodemus sylvaticusem> on the mainland and the main island, and <em>Apodemus flavicollisem> only on the mainland. The trend of some morphometric characters of the skull (incisive foramen length - FI; interorbital breadth = IO; length of palatal bridge = PP; upper alveolar length = $M^1M^3$ was analized and some theoretical models verified for <em>A. sylvaticusem>. If one considers the sympatric population of <em>A. sylvaticusem> and <em>A. flavicollisem> simultaneously the characters PP, IO and $M^1M^3$ appear significantly isometric being directly correlated ($P leq O.O1$, while FI character results allometric with respect to the previous ones, as expected. If one considers the sympatric populations of each of the species separately, the scenario is different. For <em>A. sylvaticusem> only PP and $M^1M^3$ are isometric ($P leq 0.05$. For <em>A. flavicollisem> only $M^1M^3$ and FI appear to be correlated, although not as significantly as for <em>A. sylvaticusem> ($P le 0.05$; one tail. The insular populations of <em>A. sylvaticusem> do not show significant correlations, except for FI and $M^1M^3$ ($P le 0.05$. On the contrary, considering all populations, sympatric and allopatric, of <em>A. sylvaticusem> at the same time are significant correlations ($P le 0.05$ in all combinations of characters, except for those involving the IO. We suggest that the isometric relations in sympatric assemblages are confined within a morphological range available to the genus <em>Apodemus>. In such a space, the two species are split in two different and innerly homogeneous distributions. We found no evidence to confirm the niche variation hypothesis. On the contrary, the variability expressed as SO or CV's appears higher in the sympatric populations than in the allopatric ones, for three of the four characters, confirming previous results

  19. Dione and Rhea seasonal exospheres revealed by Cassini CAPS and INMS

    Teolis, B. D.; Waite, J. H.

    2016-07-01

    A Dione O2 and CO2 exosphere of similar composition and density to Rhea's is confirmed by Cassini spacecraft Ion Neutral Mass Spectrometer (INMS) flyby data. INMS results from three Dione and two Rhea flybys show exospheric spatial and temporal variability indicative of seasonal exospheres, modulated by winter polar gas adsorption and desorption at the equinoxes. Cassini Plasma Spectrometer (CAPS) pickup ion fluxes also show exospheric structure and evolution at Rhea consistent with INMS, after taking into consideration the anticipated charge exchange, electron impact, and photo-ionization rates. Data-model comparisons show the exospheric evolution to be consistent with polar frost diffusion into the surface regolith, which limits surface exposure and loss of the winter frost cap by sputtering. Implied O2 source rates of ∼45(7) × 1021 s-1 at Dione(Rhea) are ∼50(300) times less than expected from known O2 radiolysis yields from ion-irradiated pure water ice measured in the laboratory, ruling out secondary sputtering as a major exospheric contributor, and implying a nanometer scale surface refractory lag layer consisting of concentrated carbonaceous impurities. We estimate ∼30:1(2:1) relative O2:CO2 source rates at Dione(Rhea), consistent with a stoichiometric bulk composition below the lag layer of 0.01(0.13) C atoms per H2O molecule, deriving from endogenic constituents, implanted micrometeoritic organics, and (in particular at Dione) exogenous H2O delivery by E-ring grains. Impact deposition, gardening and vaporization may thereby control the global O2 source rates by fresh H2O ice exposure to surface radiolysis and trapped oxidant ejection.

    Full Text Available Environmental management accounting (EMA is a system that collects, records, evaluates and transmits information about environmentally induced financial impacts and environmental impacts of the given system. In 2006 and 2010 there were two questionnaire surveys. The first survey was carried out under the resolution of grant, which was funded by the Internal Grant Agency of the Mendel University of Agriculture and Forestry in Brno, No. 68/2006, entitled “Development of the EMAS and environmental management accounting in the Czech Republic”. The second evaluated questionnaire survey was conducted in the study, which was made in connection with solution of the thesis of author‘s article. Group of 25 companies that had validated EMAS during the first questionnaire survey was subjected to a survey. The second questionnaire survey was carried out in the same companies in order to make evaluation of development over time. The aim of this paper is to create coherent conclusion about firms that had or have validated EMAS system and use a voluntary instrument EMA in its corporate practice. Partial aim is to evaluate the development of validated organizations and ‘sites’ with EMAS in time in EU countries. EMAS is a system of management of company and audits in terms of environmental protection. This system is applied within the European Union.

    2016-01-01

    Cassini's Composite Infrared Spectrometer (CIRS) observed both of Rhea's polar regions during a close (2000 km) flyby on 9th March 2013 during orbit 183. Rhea's southern pole was again observed during a more distant (51,000 km) flyby on 10th February 2015 during orbit 212. The results show Rhea's southern winter pole is one of the coldest places directly observed in our Solar System: surface temperatures of 25.4 +/-7.4 K and 24.7 +/-6.8 K are inferred from orbit 183 and 212 data, respectively. The surface temperature of the northern summer pole inferred from orbit 183 data is warmer: 66.6 +/-0.6 K. Assuming the surface thermophysical properties of the two polar regions are comparable then these temperatures can be considered a summer and winter seasonal temperature constraint for the polar region. Orbit 183 will provide solar longitude ( LS ) coverage at 133 deg and 313 deg for the summer and winter poles respectively, while orbit 212 provides an additional winter temperature constraint at LS 337 deg. Seasonal models with bolometric albedo values between 0.70 and 0.74 and thermal inertia values between 1 and 46 J m( exp -2) K( exp -1) s (exp -1/2) (otherwise known as MKS units) can provide adequate fits to these temperature constraints (assuming the winter temperature is an upper limit). Both these albedo and thermal inertia values agree within the uncertainties with those previously observed on both Rhea's leading and trailing hemispheres. Investigating the seasonal temperature change of Rhea's surface is particularly important, as the seasonal wave is sensitive to deeper surface temperatures ( approximately tens of centimeters to meter depths) than the more commonly reported diurnal wave (typically less than a centimeter), the exact depth difference dependent upon the assumed surface properties. For example, if a surface porosity of 0.5 and thermal inertia of 25 MKS is assumed then the depth of the seasonal thermal wave is 76 cm, which is much deeper than the

    Early thermal history of Rhea is investigated. The role of the following parameters of the model is investigated: time of beginning of accretion, tini, duration of accretion, tac, viscosity of ice close to the melting point, η0, activation energy in the formula for viscosity, E, thermal conductivity of silicate component, ksil, ammonia content, XNH3, and energy of serpentinization, cserp. We found that tini and tac are crucial for evolution. All other parameters are also important, but no dramatic differences are found for realistic values. The process of differentiation is also investigated. It is found that liquid state convection could delay the differentiation for hundreds of My. The results are confronted with observational data from Cassini spacecraft. It is possible that differentiation is fully completed but the density of formed core is close to the mean density. If this interpretation is correct, then Rhea could have accreted any time before 3-4 My after formation of CAI.

    Full Text Available The aim of this paper is to verify the effectiveness of EMA indicator according to selected time intervals. The underlying assumption is that, on longer timescales EMA is profitable and provides more relevant signals. The second objective of this paper is to test the signals of indicators in different months. It is believed that in September and January the number of trading signals on this indicator will increase. Testing will be done on the five-minute time frame. The test will be subjected to 65,000 rate values of the EUR / USD currency pair. Effectiveness of the analysis will be evaluated on the basis of digital (binary option. Business strategy is based on EMA crossover indicator of current exchange rate. By the contribution there were confirmed hypotheses about more profitable signals when selecting a greater timeframe breadth of moving average. There was also confirmed an increased amount of signals in September, but not in January.

    The importance of 16S rRNA gene amplicon profiles for understanding the influence of microbes in a variety of environments coupled with the steep reduction in sequencing costs led to a surge of microbial sequencing projects. The expanding crowd of scientists and clinicians wanting to make use of sequencing datasets can choose among a range of multipurpose software platforms, the use of which can be intimidating for non-expert users. Among available pipeline options for high-throughput 16S rRNA gene analysis, the R programming language and software environment for statistical computing stands out for its power and increased flexibility, and the possibility to adhere to most recent best practices and to adjust to individual project needs. Here we present the Rhea pipeline, a set of R scripts that encode a series of well-documented choices for the downstream analysis of Operational Taxonomic Units (OTUs) tables, including normalization steps, alpha - and beta -diversity analysis, taxonomic composition, statistical comparisons, and calculation of correlations. Rhea is primarily a straightforward starting point for beginners, but can also be a framework for advanced users who can modify and expand the tool. As the community standards evolve, Rhea will adapt to always represent the current state-of-the-art in microbial profiles analysis in the clear and comprehensive way allowed by the R language.

    The nutritional value of proteins was investigated after the storage and cooking of rhea M. Gastrocnemius pars interna. Oxidation of basic and aromatic amino acids, surface hydrophobicity and aggregation state of proteins, were determined in raw and cooked meat. In addition, myofibrillar proteins were exposed in vitro to proteases of the digestive tract. Cooking markedly affected the protein surface hydrophobicity. The BBP bound content was three times greater in cooked than in fresh rhea meat. A small increment in tryptophan content after cooking was observed. Storage influenced Schiff bases formation indicating the presence of protein-aldehyde adducts after cooking. High content of Schiff bases was found after cooking of samples stored for 5 days, demonstrating a probable implication of free amino groups, most likely from lysine. Cooking decreased the myofibrillar protein susceptibility to pepsin activity. After cooking, the proteolysis rate by pancreatic enzymes increased. Our findings support the importance of protein aggregation in the nutritional value of meat proteins. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Morphological analyses of landforms on Rhea are used to define three physiographic provinces: cratered terrain 1 undifferentiated; cratered terrain 1 lineated; and cratered terrain 2. The important statigraphic relationships between the different provinces are examined with respect to major impact basins and tectonic features. It is shown that the formation of multiringed basins may have caused, or at least controlled the locations of major resurfacing and mantling events. The diameters of the central peaks relative to the impact crater diameters are found to be significantly larger than those within the craters of the moon or Mercury. Both cratered and noncrater lineaments have regional orientations which do not fit current global or regional stress models. On the basis of the morphological analysis, a chronological order is established for the origin of the three provinces: the cratered terrain 1 province was formed first; and cratered terrain 1 lineated and cratered terrain 2 were formed second, and last, respectively. It is shown that the chronological order is generally consistent with current theoretical models of the evolution of Rhea.

    As healthcare systems continue to expand and interconnect with each other through patient sharing, administrators, policy makers, infection control specialists, and other decision makers may have to take account of the entire healthcare 'ecosystem' in infection control. We developed a software tool, the Regional Healthcare Ecosystem Analyst (RHEA), that can accept user-inputted data to rapidly create a detailed agent-based simulation model (ABM) of the healthcare ecosystem (ie, all healthcare facilities, their adjoining community, and patient flow among the facilities) of any region to better understand the spread and control of infectious diseases. To demonstrate RHEA's capabilities, we fed extensive data from Orange County, California, USA, into RHEA to create an ABM of a healthcare ecosystem and simulate the spread and control of methicillin-resistant Staphylococcus aureus. Various experiments explored the effects of changing different parameters (eg, degree of transmission, length of stay, and bed capacity). Our model emphasizes how individual healthcare facilities are components of integrated and dynamic networks connected via patient movement and how occurrences in one healthcare facility may affect many other healthcare facilities. A decision maker can utilize RHEA to generate a detailed ABM of any healthcare system of interest, which in turn can serve as a virtual laboratory to test different policies and interventions.

    1993-08-01

    The Composite Development Division of the Propulsion Laboratory at Marshall Space Flight Center (MSFC) is currently developing a class of electromechanical actuators (EMA's) for use in space transportation applications such as thrust vector control (TVC) and propellant control valves (PCV). These high power servomechanisms will require rugged, reliable, and compact power electronic modules capable of modulating several hundred amperes of current at up to 270 volts. MSFC has selected the brushless dc motor for implementation in EMA's. This report presents the results of an investigation into the applicability of two new technologies, MOS-controlled thyristors (MCT's) and pulse density modulation (PDM), to the control of brushless dc motors in EMA systems. MCT's are new power semiconductor devices, which combine the high voltage and current capabilities of conventional thyristors and the low gate drive requirements of metal oxide semiconductor field effect transistors (MOSFET's). The commanded signals in a PDM system are synthesized using a series of sinusoidal pulses instead of a series of square pulses as in a pulse width modulation (PWM) system. A resonant dc link inverter is employed to generate the sinusoidal pulses in the PDM system. This inverter permits zero-voltage switching of all semiconductors which reduces switching losses and switching stresses. The objectives of this project are to develop and validate an analytical model of the MCT device when used in high power motor control applications and to design, fabricate, and test a prototype electronic circuit employing both MCT and PDM technology for controlling a brushless dc motor.

    Spectral measurements from the ground in the time leading up to the Cassini mission at Saturn provide important context for the interpretation of the forthcoming spacecraft data. Whereas ground-based observations cannot begin to approach the spatial scales Cassini will achieve, they do possess the benefits of better spectral resolution, a broader possible time baseline, and unique veiewing geometries not obtained by spacecraft (i.e., opposition). In this spirit, we present recent NIR reflectance spectra of four icy satellites of Saturn measured with the SpeX instrument at the IRTF. These measurements cover the range 0.8-4.0 m of both the leading and trailing sides of Tethys and the leading side of Rhea. The L-band region (2.8-4.0 m) offers new opportunities for searches of minor components on these objects. Additionally, these data include 0.8-2.5 m spectra of both the leading and trailing sides of Mimas and of the (mostly) trailing side of Enceladus. The spectrum of Enceladus shows activity near 2.25 m that we interpret as a possible signature of NH3 ice. The presence of ammonia in the Saturn system is not unexpected, and may help explain the apparent recent geologic activity of Enceladus. Analysis of leading/trailing differences inH2O band depths, spectral slopes, and albedo imply a separate regime of surface modification for Mimas and Enceladus than for the more distant icy satellites (Tethys, Dione, Rhea). Aside from the potential NH3 on Enceladus, no other minor constituents are detected in these icy surfaces.

    Full Text Available Pembiayaan gadai emas di bank syariah mencuat ketika harga emas dunia mengalami fluktuasi yang cukup tajam. Hal ini mendorong masyarakat beralih kepada investasi emas. Diawali oleh BRI syariah membuka layanan gadai emas yang diidasarkan pada akad rahn dan ijaroh, namun pada praktiknya membuka prosedur layanan beli gadai yang disinyalir rentan dengan spekulasi yang dilarang oleh agama islam. Produk beli gadai selanjutnya dikenal dengan berkebun emas ini dibatasi oleh Bank Indonesia guna membatasi gerak spekulasi nasabah atas emas. Akan tetapi beberapa bank syariah seperti BNI dan BSM yang juga membuka layanan gadai emas tidak melakukan transaksi beli gadai sebagaimana BRI syariah melainkan hanya melayani gadai emas sebagaimana dalam fatwa DSN MUI No 26/DSN-MUI/III/2002. Namun transaksi gadai emas yang berjalan bukan berarti tanpa masalah ditilik dari fikih dan etika salah satunya adalah penetapan harga ijaroh yang didasarkan pada metode tiring dan taksasi pembiayaan yang diterima. Penetapan harga ijaroh dan transaksi gadai emas  dirasakan telah menyalahi konsepsi Rahn yang seharusnya didudukkan pada akad keterdesakan yang beresensi ta’awun tolong menolong.

The first reports of the professional and sport fishing there date back from the 30's, which is the same period when the tourism took place. The present paper provides an environmental valuation of this place and an assessment of the differences among the major groups of people using the area. During 2006 we interviewed 33 professional fishers, 107 sport fishers, 45 tourists and 103 excursionists in order to estimate the Willingness to Pay (WTP for each category and to analyze the influence of socioeconomic factors by means of logistic regressions and ANCOVAs. The WTP of professional fisher was significantly influenced by age and education, and the WTP for the sport fishers was influenced by the family income. The variables that influenced the tourists' and excursionists' WTP were sex and education. The total annual aggregated value to maintain the waterfall in the current conditions was estimated in US$ 11.432.128, and US$ 55.424.283 to restore it.A Cachoeira de Emas, no Rio Mogi-Guaçu, é reconhecida regionalmente como um importante local para a pesca e o turismo.

    Social insect polyphenisms provide models to examine the neural basis of division of labor and anatomy of the invertebrate social brain. Worker size-related behavior is hypothesized to enhance task performance, raising questions concerning the integration of morphology, behavior, and cellular neuroarchitecture, and how variation in sensory inputs and cognitive demands of behaviorally differentiated workers is reflected in higher-order processing ability. We used the highly polymorphic ant Pheidole rhea, which has three distinct worker size classes - minors, soldiers, and supersoldiers - to examine variation in synaptic circuitry across worker size and social role. We hypothesized that the density and size of synaptic complexes (microglomeruli, MG) would be positively associated with behavioral repertoire and the relative size of the mushroom bodies (MB). Supersoldiers had significantly larger and less dense MG in the lip (olfactory region) of the MB calyx (MBC), and larger MG in the collar (visual region) compared to minors. Soldiers were intermediate in synaptic phenotype: they did not differ significantly in MG density from minors and supersoldiers, had MG of similar size to minors in the lip, and did not differ from these two worker groups in MG size in the collar. Results suggest a complex relationship between MG density, size, behavior, and worker body size involving a conserved and plastic neurobiological development plan, although workers show strong variation in size and social role.

    The Component Development Division of the Propulsion Laboratory at Marshall Space Flight Center (MSFC) is currently developing a class of electromechanical actuators (EMA's) for use in space transportation applications such as thrust vector control (TVC) and propellant control valves (PCV). These high power servomechanisms will require rugged, reliable, and compact power electronic modules capable of modulating several hundred amperes of current at up to 270 volts. MSFC has selected the brushless dc motor for implementation in EMA's. A previous project performed by Auburn University examined the use of the resonant dc link (RDCL) inverter, pulse density modulation (PDM), and mos-controlled thyristors (MCT's) for speed control of a brushless dc motor. The speed of the brushless dc motor is proportional to the applied stator voltage. In a PDM system, the control system determines the number of resonant voltage pulses which must be applied to the stator to achieve a desired speed. The addition of a waveshaping circuit to the front end of a standard three-phase inverter yields a RDCL inverter; the resonant voltage pulses are produced through the action of this wave shaping circuit and the inverter. This project has focused on the implementation of a system which permits zero-voltage switching with the bus voltage clamped at the input voltage level. In the same manner as the RDCL inverter, the inverter selected for this implementation is a combination of waveshaping circuit and a standard three-phase inverter. In addition, this inverter allows a pulse-width modulated (PWM)-like control scheme instead of a PDM scheme. The operation of waveshaping circuit will be described through analysis and waveforms. Design relationships will also be presented.

  11. Tectonic and volcanic history of Rhea as inferred from studies of scarps, ridges, troughs, and other lineaments

    The 13 geomorphic feature types presently defined through the analysis of landforms on Rhea are with only one exception interpretable as of tectonic or volcanic-tectonic origin. The troughs, grabens, grooves, pit chains, scarps, and other lineaments are purely extensional in nature, while the ridges are volcanic features formed in an extensional stress field; this extension was followed by a global compression era generating megaridges and megascarps. The extensional landforms seem to form a global grid pattern that is directionally similar to the theoretically projected pattern of a tidally distorted planet. 17 references

    Full Text Available The purpose of the study was to investigate the antioxidant characteristics of <em>Anisomeles indicaem> methanol extract and the inhibitory effect of ovatodiolide on melanogenesis. In the study, the antioxidant capacities of <em>A. indicaem> methanol extract such as DPPH assay, ABTS radical scavenging assay, reducing capacity and metal ion chelating capacity as well as total phenolic content of the extract were investigated. In addition, the inhibitory effects of ovatodiolide on mushroom tyrosinase, B16F10 intracellular tyrosinase and melanin content were determined spectrophotometrically. Our results revealed that the antioxidant capacities of <em>A. indicaem> methanol extract increased in a dose-dependent pattern. The purified ovatodiolide inhibited mushroom tyrosinase activity (IC50 = 0.253 mM, the compound also effectively suppressed intracellular tyrosinase activity (IC50 = 0.469 mM and decreased the amount of melanin (IC50 = 0.435 mM in a dose-dependent manner in B16F10 cells. Our results concluded that <em>A. indicaem> methanol extract displays antioxidant capacities and ovatodiolide purified from the extract inhibited melanogenesis in B16F10 cells. Hence, <em>A. indicaem> methanol extract and ovatodiolide could be applied as a type of dermatological whitening agent in skin care products.

  13. Early thermal history of Rhea: the role of serpentinization and liquid state convection

    Czechowski, Leszek; Losiak, Anna

    2015-04-01

    Intorduction: Thermal history of Rhea from the beginning of accretion is investigated. The numerical model of convection combined with the parameterized theory is developed. Melting of the satellite's matter, gravitational differentiation and serpentinization of silicates are included. The role of the following parameters of the model is investigated: time of beginning of accretion, duration of accretion, viscosity of ice close to the melting point, activation energy in the formula for viscosity E, thermal conductivity of silicate component, ammonia content X, and energy of serpentinization. 1. Numerical model: In our calculations we use numerical model developed by Czechowski (2012) (see e.g. description in [1]). The model is based on parameterized theory of convection combined with 1-dimensional equation of the heat transfer in spherical coordinates: δT(r,t)- ρcp δt = div(k(r,T ) gradT (r,t))+ Q(r,T), where r is the radial distance (spherical coordinate), ρ is the density [kg m-3], cp [J kg1 K-1 ] is the specific heat, Q [W kg-1] is the heating rate, and k[W m-1 K-1] is the thermal conductivity. Q(r,t) includes sources and sinks of the heat. The equation is solved in time dependent region [0, R(t)]. During accretion the radius R(t) increases in time according to formula: R(t) = atfor tini tac , i.e. after the accretion (see e.g. [2]), where tinidenotes beginning of accretion and tac denotes duration of this process. If the Rayleigh number in the considered layer exceeds its critical value Racr then convection starts. It leads to effective heat transfer. The full description of convection is given by a velocity field and temperature distribution. However, we are interested in convection as a process of heat transport only. For solid state convection (SSC) heat transport can be described by dimensionless Nusselt number Nu. We use the following definition of the Nu: Nu= (True total surface heat flow)/(Total heat flow without convection). The heat transport by

    Rhea (Rhea americana) muscles Obturatorius medialis (OM) Iliotibialis lateralis (IL) and Iliofibularis (I), obtained from farmed animals, were evaluated regarding their oxidative/antioxidant status. The mean level of thiobarbituric acid reactive substances (TBARS) expressed as malonaldehyde (MDA) content was of 0.84 mg MDA/kg wet tissue for the three muscles. TBARS level was significantly higher in IL than OM and I, with the two latter showing similar levels. The mean level of carbonyl proteins expressed as dinitrophenylhydrazine (DNPH) was 1.59 nmol DNPH mg(-1). Carbonyl protein levels were significantly different (POM>I). Iron-induced TBARS generation was not significantly different between the three muscles at any time, nor for each muscle during the 5 h of the experiment. Superoxide dismutase activity in IL muscle was significantly higher (P<0.05) than in I muscle. However, the difference between IL and OM muscles was not significant. The differences between the three muscles became not significant when the results were expressed by mg of protein contained in the extract, instead by g of wet tissue. No differences were found for catalase (micromol of discomposed H(2)O(2) min(-1) g(-1) wet tissue or by mg of protein contained in the extract) and glutathione peroxidase (micromol ol of oxidized NADPH min(-1) g(-1) of wet tissue or by mg of protein contained in the extract) activities between the three muscles. 2009 Elsevier Ltd.

    The electromagnetic articulograph (EMA) is a device that can collect movement data by positioning sensors at multiple points, measuring displacements of the structure in real time, as well as the acoustics and mechanics of speech using a microphone connected to the measurement system. The aim of this study is to describe protocols for the generation, measurement and visualization of mandibular border and functional movements in the three spatial planes (frontal, sagittal and horizontal) using the EMA. The EMA has transmitter coils that determine magnetic fields to collect information about movements from sensors located on different structures (tongue, palate, mouth, incisors, skin, etc.) and in every direction in an area of 300 mm. After measurement with the EMA, the information is transferred to a computer and read with the Visartico software to visualize the recording of the mandibular movements registered by the EMA. The sensors placed in the space between the three axes XYZ are observed, and then the plots created from the mandibular movements included in the corresponding protocol can be visualized, enabling interpretation of these data. Four protocols for the obtaining of images of the opening and closing mandibular movements were defined and developed, as well as border movements in the frontal, sagittal and horizontal planes, managing to accurately reproduce Posselt's diagram and Gothic arch on the latter two axes. Measurements with the EMA will allow more exact data to be collected in relation to the mandibular clinical physiology and morphology, which will permit more accurate diagnoses and application of more precise and adjusted treatments in the future.

    2011-01-01

    This paper introduces a 4-DOFs exoskeletal meal assistance system (EMAS II) for progressive muscle dystrophy patient. It is generally better for the patient to use his/her hands by himself in daily life because active works maintain level of residual functions, health and initiative of him/her. The EMAS II that has a new joystick-type user interface device and three-DOFs on a shoulder part is enhanced for an easier operation and more comfortable support on eating, as the succeeding model of the previous system that has two-DOFs on a shoulder. In order to control the 4-DOFs system by the simple user interface device, the EMAS II simulates upper limb motion patterns of a healthy person. The motion patterns are modeled by extracting correlations between the height of a user's wrist joint and that of the user's elbow joint at the table. Moreover, the EMAS II automatically brings user's hand up to his/her mouth or back to a table when he/she pushes a preset switch on the interface device. Therefore a user has only to control a position of his/her wrist to pick or scoop foods and then flip the switch to start automatic mode, while a height of the elbow joint is automatically controlled by the EMAS II itself. The results of experiments, where a healthy subject regarded as a muscle dystrophy patient eats a meal with EMAS II, show that the subject finished her meal in a natural way in 18 minutes 40 seconds which was within a recommended time of 30 minutes. © 2011 IEEE

    Full Text Available Chronic bee paralysis virus (CBPV infection causes chronic paralysis and loss of workers in honey bee colonies around the world. Although CBPV shows a worldwide distribution, it had not been molecularly detected in Japan. Our investigation of <em>Apis melliferaem> and <em>Apis cerana japonicaem> colonies with RT-PCR has revealed CBPV infection in <em>A. melliferaem> but not <em>A. c. japonicaem> colonies in Japan. The prevalence of CBPV is low compared with that of other viruses: deformed wing virus (DWV, black queen cell virus (BQCV, Israel acute paralysis virus (IAPV, and sac brood virus (SBV, previously reported in Japan. Because of its low prevalence (5.6% in <em>A. melliferaem> colonies, the incidence of colony losses by CBPV infection must be sporadic in Japan. The presence of the (− strand RNA in dying workers suggests that CBPV infection and replication may contribute to their symptoms. Phylogenetic analysis demonstrates a geographic separation of Japanese isolates from European, Uruguayan, and mainland US isolates. The lack of major exchange of honey bees between Europe/mainland US and Japan for the recent 26 years (1985–2010 may have resulted in the geographic separation of Japanese CBPV isolates.

    To investigate the sensitivity and specificity of eosin-5'-maleimide (EMA)assay for the diagnosis of hereditary spherocytosis (HS), and to verify the stability of reagent and samples. EMA flow cytometry test, NaCl-osmotic fragility test and acidified glycerol lysis test were performed using peripheral blood samples from 80 patients with HS and 44 patients with other blood diseases, the sensitivity and specificity of the three methods were compared, and the feasibility of EMA binding test was estimated. The stability of EMA reagent and HS samples stored at different temperatures were tested. Among the 124 tested samples, the sensitivity and specificity of EMA binding test was 0.925 and 0.954, that of NaCl-osmotic fragility test was 0.950 and 0.455, and that of acidified glycerol lysis test was 1.000 and 0.318, respectively. Although the sensitivity of NaCl-osmotic fragility test and acidified glycerol lysis test was a little higher than that of EMA binding test, the specificity of the former two methods was poor, they couldn't clearly distinguish whether spherocytosis is hereditary spherocytosis. The experiment results showed that EMA was sensitive to the temperature and should not be stored in a small aliquots at -80 ℃ over a period of 6 months. The stability of the HS sample was better, 6 days storage at 4 ℃ and 3 days storage at room temperature had no influence on the results. EMA binding test by flow cytometry showed good sensitivity and specificity for HS diagnosis. EMA reagent should be stored at-80 ℃ and the HS samples should be tested within 6 days storage at 4 ℃ and 3 days at room temperature.

    A combination of Finite Element Method (FEM) and Experiment Modal Analysis (EMA) have been employed here to characterize the structural dynamic response of mechanical elastic wheel (ME-Wheel) operating under a specific thermal environment. The influence of high thermal condition on the structural dynamic response of ME-Wheel is investigated. The obtained results indicate that the EMA results are in accordance with those obtained using the proposed Finite Element (FE) model, indicting the high reliability of this FE model applied in analyzing the modal of ME-Wheel working under practical thermal environment. It demonstrates that the structural dynamic response of ME-Wheel operating under a specific thermal condition can be predicted and evaluated using the proposed analysis method, which is beneficial for the dynamic optimization design of the wheel structure to avoid tire temperature related vibration failure and improve safety of tire.

  15. BCL::EMAS — Enantioselective Molecular Asymmetry Descriptor for 3D-QSAR

    Directory of Open Access Journals (Sweden)

    2012-08-01

    Full Text Available Stereochemistry is an important determinant of a molecule’s biological activity. Stereoisomers can have different degrees of efficacy or even opposing effects when interacting with a target protein. Stereochemistry is a molecular property difficult to represent in 2D-QSAR as it is an inherently three-dimensional phenomenon. A major drawback of most proposed descriptors for 3D-QSAR that encode stereochemistry is that they require a heuristic for defining all stereocenters and rank-ordering its substituents. Here we propose a novel 3D-QSAR descriptor termed Enantioselective Molecular ASymmetry (EMAS that is capable of distinguishing between enantiomers in the absence of such heuristics. The descriptor aims to measure the deviation from an overall symmetric shape of the molecule. A radial-distribution function (RDF determines a signed volume of tetrahedrons of all triplets of atoms and the molecule center. The descriptor can be enriched with atom-centric properties such as partial charge. This descriptor showed good predictability when tested with a dataset of thirty-one steroids commonly used to benchmark stereochemistry descriptors (r2 = 0.89, q2 = 0.78. Additionally, EMAS improved enrichment of 4.38 versus 3.94 without EMAS in a simulated virtual high-throughput screening (vHTS for inhibitors and substrates of cytochrome P450 (PUBCHEM AID891.

    The spatial and temporal pattern of appearance of nestin, epithelial membrane antigen (EMA) and mesothelin proteins was immunohistochemically determined in the cells of normal developing and adult human meninges and meningiomas. Human meninges developed as two mesenchymal condensations in the head region. The simple squamous epithelium on the surface of leptomeninges developed during mesenchymal to epithelial transformation. Nestin appeared for the first time in week 7, EMA in week 8, while mesothelin appeared in week 22 of development. In the late fetal period and after birth, nestin expression decreased, whereas expression of EMA and mesothelin increased. EMA appeared in all surface epithelial cells and nodules, while mesothelin was found only in some of them. In adult meninges, all three proteins were predominantly localized in the surface epithelium and meningeal nodules. In meningothelial meningiomas (WHO grade I), EMA was detected in all tumor cells except in the endothelial cells, mesothelin characterized nests of tumor cells, while nestin was found predominantly in the walls of blood vessels. The distribution pattern of those proteins in normal meningeal and tumor cells indicates that nestin might characterize immature cells, while EMA and mesothelin appeared in maturing epithelial cells. Neoplastic transformation of these specific cell lineages contributes to the cell population in meningiomas. Copyright © 2010 Elsevier GmbH. All rights reserved.

    Early-life nutrition is critical for optimal brain development; however, few studies have evaluated the impact of diet as a whole in early childhood on neurological development with inconsistent results. The present analysis is a cross-sectional study nested within an ongoing prospective birth cohort, the Rhea study, and aims to examine the association of dietary patterns with cognitive and psychomotor development in 804 preschool (mean age 4·2 years) children. Parents completed a validated FFQ, and dietary patterns were identified using principal component analysis. Child cognitive and psychomotor development was assessed by the McCarthy Scales of Children's Abilities (MSCA). Multivariable linear regression models were used to investigate the associations of dietary patterns with the MSCA scales. After adjustment for a large number of confounding factors, the 'Snacky' pattern (potatoes and other starchy roots, salty snacks, sugar products and eggs) was negatively associated with the scales of verbal ability (β=-1·31; 95 % CI -2·47, -0·16), general cognitive ability (β=-1·13; 95 % CI -2·25, -0·02) and cognitive functions of the posterior cortex (β=-1·20; 95 % CI -2·34, -0·07). Further adjustment for maternal intelligence, folic acid supplementation and alcohol use during pregnancy attenuated the observed associations, but effect estimates remained at the same direction. The 'Western' and the 'Mediterranean' patterns were not associated with child neurodevelopmental scales. The present findings suggest that poorer food choices at preschool age characterised by foods high in fat, salt and sugar are associated with reduced scores in verbal and cognitive ability.

    To propose a new Extended Monopole antenna Array with individual Shields (EMAS) coil that improves the B1 field coverage and uniformity along the z-direction. To increase the spatial coverage of Monopole antenna Array (MA) coil, each monopole antenna was shielded and extended in length. Performance of this new coil, which is referred to as EMAS coil, was compared with the original MA coil and an Extended Monopole antenna Array coil with no shield (EMA). For comparison, flip angle, signal-to-noise ratio (SNR), and receive sensitivity maps were measured at multiple regions of interest (ROIs) in the brain. The EMAS coil demonstrated substantially larger flip angle and receive sensitivity than the MA and EMA coils in the inferior aspect of the brain. In the brainstem ROI, for example, the flip angle in the EMAS coil was increased by 45.5% (or 60.0%) and the receive sensitivity was increased by 26.9% (or 14.9%), resulting in an SNR gain of 84.8% (or 76.3%) when compared with the MA coil (or EMA). The EMAS coil provided 25.7% (or 24.4%) more uniform B1+ field distribution compared with the MA (or EMA) coil in sagittal. The EMAS coil successfully extended the imaging volume in lower part of the brain. Magn Reson Med 75:2566-2572, 2016. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

On this basis european common rules are necessary and European Commission issued Regulation 1836/93 known also as EMAS - Environmental Management and Audit Scheme-that is proposing to industries a voluntary adhesion to it. Rational Use of Energy can be integrated in this Management and Audit scheme because of his direct effect on emission and resources` consumption. Therefore energy efficiency is a primary need for an industry not only for its social aspect but also for its strategic impact on market success.

    The cytochrome P450 monooxygenase Ema1 from Streptomyces tubercidicus R-922 and its homologs from closely related Streptomyces strains are able to catalyze the regioselective oxidation of avermectin into 4"-oxo-avermectin, a key intermediate in the manufacture of the agriculturally important insecticide emamectin benzoate (V. Jungmann, I. Molnár, P. E. Hammer, D. S. Hill, R. Zirkle, T. G. Buckel, D. Buckel, J. M. Ligon, and J. P. Pachlatko, Appl. Environ. Microbiol. 71:6968-6976, 2005). The gene for Ema1 has been expressed in Streptomyces lividans, Streptomyces avermitilis, and solvent-tolerant Pseudomonas putida strains using different promoters and vectors to provide biocatalytically competent cells. Replacing the extremely rare TTA codon with the more frequent CTG codon to encode Leu4 in Ema1 increased the biocatalytic activities of S. lividans strains producing this enzyme. Ferredoxins and ferredoxin reductases were also cloned from Streptomyces coelicolor and biocatalytic Streptomyces strains and tested in ema1 coexpression systems to optimize the electron transport towards Ema1.

    Full Text Available Single nucleotide polymorphisms (SNPs are currently the marker of choice in a variety of genetic studies. Using the high resolution melting (HRM genotyping approach, 101 gene-based SNP markers were developed for <em>Apostichopus japonicusem>, a sea cucumber species with economic significance for the aquaculture industry in East Asian countries. HRM analysis revealed that all the loci showed polymorphisms when evaluated using 40 <em>A. japonicusem> individuals collected from a natural population. The minor allele frequency ranged from 0.035 to 0.489. The observed and expected heterozygosities ranged from 0.050 to 0.833 and 0.073 to 0.907, respectively. Thirteen loci were found to depart significantly from Hardy–Weinberg equilibrium (HWE after Bonferroni corrections. Significant linkage disequilibrium (LD was detected in one pair of markers. These SNP markers are expected to be useful for future quantitative trait loci (QTL analysis, and to facilitate marker-assisted selection (MAS in <em>A. japonicusem>.

    Full Text Available The Small hive beetle, <em>Aethina tumidaem>, is an invasive pest of honey bees. Indigenous to sub-Saharan Africa, it has now become established in North America and Australia. It represents a serious threat to European honey bees. Commercially available entomopathogenic agents were screened for their potential to control beetle larvae. Entomopathogenic fungi investigated had minimal impact. The nematodes <em>Steinernema> krausseiem> and <em>S. carpocapsaeem> provided excellent control with 100% mortality of larvae being obtained. Sequential applications of the nematodes following larvae entering sand to pupate also provided excellent control for up to 3 weeks. The information gained supports the development of contingency plans to deal with <em>A. tumidaem> should it occur in the UK, and is relevant to the management of Small hive beetle where it is already present.

    Eosin-5'-maleimide (EMA) binding test is a flow cytometric test used to detect hereditary spherocytosis (HS). To perform the test sample from patients, 5-6 reference samples of red blood are needed. Our aim was to investigate how the mean corpuscular volume (MCV) of red blood cells influences on the value of fluorescence of bounded EMA dye and how the choice of reference samples affects the test result. EMA test was performed in peripheral blood from 404 individuals, including 31 children suffering from HS. Mean fluorescence channel of EMA-RBCs was measured with Cytomics FC500 flow cytometer. Mean corpuscular volume of RBCs was assessed with LH750 Beckman Coulter. Statistical analysis was performed using Graph Pad Prism. The correlation Spearman coefficient between mean channel of fluorescence of EMA-RBCs and MCV was r = 0.39, p < 0.0001. Interpretation of EMA test depends on MCV of the reference samples. If reference blood samples have lower MCV than the patients MCV, EMA test result might be negative. Due to different MCV values of RBCs in infancy and ca. Three months later, EMA test in neonates might be interpreted falsely negative. Samples from children younger than 3 months old had EMA test result 86.1 ± 11.7 %, whereas same samples that analyzed 4.1 ± 2.1 later had results of 75.4 ± 4.5 %, p < 0.05. Mean fluorescence of EMA-bound RBC depends on RBC's volume. MCV of reference samples affects EMA test results; thus, we recommend selection of reference samples with MCV in range of ±2 fL compared to MCV of patient RBC's.

    This volume of IOP Conference Series: Materials Science and Engineering contains papers from the 12th Workshop of the European Microbeam Analysis Society (EMAS) on Modern Developments and Applications in Microbeam Analysis, which took place from the 15-19 May 2011 in the Angers Congress Centre, Angers, France. The primary aim of this series of workshops is to assess the state-of-the-art and reliability of microbeam analysis techniques. The workshops also provide a forum where students and young scientists starting out on a career in microbeam analysis can meet and discuss with the established experts. The workshops have a very specific format comprising invited plenary lectures by internationally recognized experts, poster presentations by the participants and round table discussions on the key topics led by specialists in the field. This workshop was organized in collaboration with GN-MEBA - Groupement National de Microscopie Electronique à Balayage et de microAnalysis, France. The technical programme included the following topics: the limits of EPMA, new techniques, developments and concepts in microanalysis, microanalysis in the SEM, and new and less common applications of micro- and nanoanalysis. As at previous workshops there was also a special oral session for young scientists. The best presentation by a young scientist was awarded with an invitation to attend the 2012 Microscopy and Microanalysis meeting at Phoenix, Arizona. The prize went to Pierre Burdet, of the Federal Institute of Technology of Lausanne (EPFL), for his talk entitled '3D EDS microanalysis by FIB-SEM: enhancement of elemental quantification'. The continuing relevance of the EMAS workshops and the high regard in which they are held internationally can be seen from the fact that 74 posters from 18 countries were on display at the meeting, and that the participants came from as far away as Japan, Canada and the USA. A selection of participants with posters were invited to give a short oral

    The application of the eco-management and audit scheme ordinance to small hydro-power-plants deals with the possibility to take an environmental-relevant audition on sites of small hydro-power-plants to achieve the environmental EMAS-certificate. Within the realization of the acquired improvement steps also the efficiency of the power plants should be increased that the audit also becomes interesting in economic matters. Contents: after explaining the legal frame being prescribed by the European Community, its interpretation and relevance for the sites of SHP, common impacts of these on the environment are particularized. From these facts a valuation-catalogue has been developed, which will be used by the power plant-owners for the assessment of their sites to take part in the EMAS-system. This catalogue is split up into six modules, which comprise all possible valuation areas which can appear concerning the different kinds of plants. These modules are: MODUL A: backwater area; MODUL B: weir; MODUL C: powerhouse; MODUL D: tail water area; MODUL E: diversion channel / penstock; MODUL F: diversion section. Furthermore three submodules to gather common data concerning plant and river have been created. At the development of the catalogue there was particularly attached importance to a user-friendly application. The goal was to realize the valuation by the plant owners to minimize costs. To take objectiveness into account the module-catalogue was created in a way that auditors (the power plant owners) must not formulate specifications by themselves; the possible assessments only have to be marked with a cross at the corresponding parameters, which have been listed up.

    With the release of Regulation 1394/2007, a new framework for gene and cell therapy medicinal products and tissue-engineered products was established in the European Union. For all three product classes, called advanced therapy medicinal products, a centralised marketing authorisation became mandatory. The European Medicines Agency (EMA) together with its Committee for Advanced Therapies, Committee for Human Medicinal Products and the network of national agencies is responsible for scientific evaluation of the marketing authorisation applications. For a new application, data and information relating to manufacturing processes and quality control of the active substance and the final product have to be submitted for evaluation together with data from non-clinical and clinical safety and efficacy studies. Technical requirements for ATMPs are defined in the legislation, and guidance for different products is available through several EMA/CAT guidelines. Due to the diversity of ATMPs, a tailored approach for regulating these products is considered necessary. Thus, a risk-based approach has been introduced for ATMPs allowing flexibility for the regulatory requirements. Since the regulatory framework for ATMPs was established, five products have been licenced in the European Union. However, the pipeline of new ATMPs is much bigger, as seen from the significant numbers of different products discussed by the CAT in scientific advice and classification procedures. In 2013, a public consultation on the ATMP Regulation was conducted by the European Commission, and the results were published in 2014. The report proposes several improvements for the current framework and established procedures for the regulation of ATMPs.

    In order to assure the structural integrity of reactor pressure vessels (RPVs), the fracture toughness of the ferritic steels used to fabricate the RPV must be shown to be adequate during their entire operating life, including extended license life. The Charpy V-notch (CVN) impact test has been used in the nuclear industry since it uses a small test specimen that can be irradiated in surveillance programs and provides an indirect way of assessing the fracture toughness of RPV steels. The effects of embrittlement typically are characterized by changes to the average Charpy curves measured before and after irradiation: shift of the 30 ft-lb (41 J) index temperature, and decrease in the CVN upper shelf energy (USE). Requirements in the USA for the USE of RPV belt-line materials are codified in Title 10, Code of Federal Regulations, Part 50 (10 CFR 50), Appendix G. Before irradiation, USE in the transverse (T-L) orientation for base materials and crack extension in the welding direction for weld materials must be greater than or equal to 75 ft-lb (102 J), and it is not to become less than 50 ft-lb (68 J) due to radiation embrittlement throughout the license of the RPV. If the projected USE of any RPV belt-line steel falls below 50 ft-lb (68 J), the projected value must be demonstrated to provide a margin of safety against ductile fracture equivalent to that required by Appendix G of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, Section XI. The analytical evaluation method used is called an equivalent margin analysis (EMA). This paper reviews the current status of EMAs and recommends improvements and clarifications that can be made to meet the needs of extended license life to 80 years. Focus is placed on analytical methodology, material property needs and proper implementation. (authors)

  2. High Voltage EEE Parts for EMA/EHA Applications on Manned Launch Vehicles

    2011-01-01

    The objective of this paper is an assessment of high voltage electronic components required for high horsepower electric thrust vector control (TVC) systems for human spaceflight launch critical application. The scope consists of creating of a database of available Grade 1 electrical, electronic and electromechanical (EEE) parts suited to this application, a qualification path for potential non-Grade 1 EEE parts that could be used in these designs, and pathfinder testing to validate aspects of the proposed qualification plan. Advances in the state of the art in high power electric power systems enable high horsepower electric actuators, such as the electromechnical actuator (EMA) and the electro-hydrostatic actuator (EHA), to be used in launch vehicle TVC systems, dramaticly reducing weight, complexity and operating costs. Designs typically use high voltage insulated gate bipolar transistors (HV-IGBT). However, no Grade 1 HV-IGBT exists and it is unlikely that market factors alone will produce such high quality parts. Furthermore, the perception of risk, the lack of qualification methodoloy, the absence of manned space flight heritage and other barriers impede the adoption of commercial grade parts onto the critical path. The method of approach is to identify high voltage electronic component types and key parameters for parts currently used in high horsepower EMA/EHA applications, to search for higher quality substitutes and custom manufacturers, to create a database for these parts, and then to explore ways to qualify these parts for use in human spaceflight launch critical application, including grossly derating and possibly treating hybrid parts as modules. This effort is ongoing, but results thus far include identification of over 60 HV-IGBT from four manufacturers, including some with a high reliability process flow. Voltage ranges for HV-IGBT have been identified, as has screening tests used to characterize HV-IGBT. BSI BS ISO 21350 Space systems Off

    Studies of grasslands on specific soil types suggest that different nutrients can limit biomass production and, hence, species composition and number. The Brazilian cerrado is the major savanna region in America and once covered about 2 million km(2), mainly in the Brazilian Central Plateau, under seasonal climate, with wet summer and dry winter. In view of the importance of soil chemical factors in the distribution of the vegetation forms within the Cerrado domain and which may influence the number of species, we analyzed some soil characteristics in three herbaceous vegetation forms -- hyperseasonal cerrado, seasonal cerrado, and wet grassland -- in Emas National Park, a core cerrado site, to investigate the relationship between number of species and soil characteristics. We collected vegetation and soil samples in these three vegetation forms and submitted the obtained data to multiple linear regression. We found out that aluminum and pH were the best predictors of species density, the former positively related to species density and the latter negatively related. Since the predictable variation in species density is important in determining areas of conservation, we can postulate that these two soil factors are indicators of high species density areas in tropical grasslands, which could be used in selecting priority sites for conservation.

    Estuary is a place of accumulation of the population’s actitivites produced by domestic, industry or agriculture. This research was conducted to three of estuary of the rivers around the waters of Port of Tanjung Emas Semarang (PTES). They were estuaries of Baru river, Banjir Kanal Timur (BKT) and Siangker in west monsoon from October to December 2015. The purpose of this research was to analyze pollution index, the abundance of microorganisms either phytoplankton or zooplankton, the content of heavy metal in sediment and sea water, biological index that included diversity (H), uniformity (e), dominance (D), Saprobik Index (SI), and the Total of Saprobik Index (TSI) in the waters either HTL (High Tide Level) or LTL (Low Tide Level). The concentration of heavy metal in both sea water and sediments were analyzed by using Atomic Absorption Spectrophotometer (AAS). The result obtained from 12 parameters which were tested showed that the three waters can be categorized at heavily polluted condition at each value from 12.52 to 24.98. The concentration of heavy metal at sea water during HTW and LTW ranging from Cd is around 0.033 and 0. 048 mg/kg, Cu 0.047 and 0.07 mg/kg, Pb 0.48 and 0.71 mg/kg, and Zn 0.043 and 0.057 mg/kg. The saprobity value index based on the existence of phytoplankton or zooplankton was ranging of Oligosaprobik at low pollution or has not been polluted yet.

    Full text: The EMA beamline (Extreme condition X-ray Methods of Analysis) is one of the hard x-ray undulator beamlines within the first phase of the new synchrotron source in Brazil (Sirius project). This beamline is thought to make a difference where a high brilliance (high flux of up to 2 x 10 14 photons/sec with beam size down to 0.5 x 0.5 μm 2 ) is essential, which is the case for extreme pressures that require small focus and time-resolved that require high photon flux. With that in mind we propose the beamline to have two experimental hutches to cover most of the extreme condition techniques today employed at synchrotron laboratories worldwide. These two stations are thought to provide the general infrastructure for magnets and lasers experiments, which may evolve as new scientific problems appear. In addition to the hutches, support laboratories will be strongly linked and supportive to the experiments at the beamline, covering high pressure instrumentations using diamond anvil cells and pump-and-probe requirements for ultrafast and high power lasers. Along these lines, we will describe the following techniques covered at this beamline: magnetic spectroscopy (XMCD) and scattering (XRMS) under high pressure and very low temperature in order to fully probe both ferromagnetic and antiferromagnetic materials and the dependence with pressure; extreme pressure and temperature XRD and XAS experiments using very small diamond culet anvils and high power lasers.

    Full Text Available CONTEXT: Patients with autoimmune rheumatologic conditions and celiac disease tend to have a variety of autoantibodies, many of which have no clear pathogenic role. The literature contains frequent reports of celiac disease being more prevalent in patients with rheumatologic diseases, although this remains controversial. OBJECTIVES: To investigate the prevalence of positive serum tests for celiac disease, particularly IgA and IgG antigliadin (AGA antibodies and IgA antiendomysium antibodies (EmA in patients with autoimmune rheumatologic diseases. A second aim was to correlate positive serum tests with prednisone and immunosuppressant medication. METHODS: A total of 190 adults and pediatric patients with a variety of autoimmune rheumatologic diseases (systemic lupus erythematosus, rheumatoid arthritis, juvenile rheumatoid arthritis and spondyloarthrophathies were evaluated and tested for IgA and IgG antigliadin-antibodies and IgA antiendomysium antibodies. Patients with positive serum tests underwent endoscopic duodenal biopsies for pathology studies. RESULTS: There were four positive sera (2.1% for AGA IgA, all of which tested negative for AGA IgG and EmA. Three sera (1.6% tested positive for AGA IgG; all were negative for AGA IgA and EmA. The EmA test at a 1:2.5 serum dilution tested positive in 94 patients (49.5%; at a 1:5 serum dilution it was positive in 41 patients (21.6%. Eleven subjects tested positive for EmA at 1:40 dilution; and all of these tested negative for IgA tissue antitransglutaminase (tTG antibodies. Nine of the 11 EmA-positive patients and all 7 patients with positive antigliadin antibodies tests underwent duodenal endoscopic biopsies, and no significant changes were demonstrated in their duodenal mucosa. A positive EmA was associated with elevated optical density AGA IgA readings; however, there was no relationship between positive EmA and AGA IgG optical density readings. Prednisone and immunosuppressant use were unrelated

    Decades of research demonstrate the pernicious effects of targeted cigarette marketing on young people. Now, with tobacco marketing shifting toward greater incorporation of alternative products, it is critical to identify current attitudes toward the new landscape of tobacco advertisements. The purpose of this study was to understand the present landscape of tobacco marketing to which young adults are exposed, and to assess how they respond to it. During 2015-2016, we used ecological momentary assessment (EMA), in which 44 young adults (aged 18-28) carried smartphones equipped with a survey app. Seventy-seven percent were ever-users of tobacco and 29.5% were intermittent users of tobacco (someday users of cigarettes and/or those who used another tobacco product >5 times within the past year). For ten days, participants were prompted at three random times/day to complete a brief survey about their exposures and responses to tobacco-related advertising. Analyses used t-test and multilevel modeling. Intermittent users reported greater exposure than non-intermittent users to tobacco advertising. Further, both intermittent and ever-users reported more positive attitudes toward the tobacco advertising. Of the tobacco advertisements reported, 22% were for products unregulated by the FDA at the time of data collection. Conclusions/Importance: These findings indicate that young adults, and especially young adults who use tobacco, are exposed to a fair amount of tobacco advertising on a weekly basis. As the tobacco users in our sample were largely experimental and occasional users, these marketing exposures could put young adults at risk for progression toward regular use.

  11. Food cravings in everyday life: An EMA study on snack-related thoughts, cravings, and consumption.

    Food craving refers to an intense desire to consume a specific food and is regularly experienced by the majority of individuals. Yet, there are interindividual differences in the frequency and intensity of food craving experiences, which is often referred to as trait food craving. The characteristics and consequences of trait and state food craving have mainly been investigated in questionnaire-based and laboratory studies, which may not reflect individuals' behavior in daily life. In the present study, sixty-one participants completed the Food Cravings Questionnaire-Trait-reduced (FCQ-T-r) as measure of trait food craving, followed by seven days of Ecological Momentary Assessment (EMA), during which they reported snack-related thoughts, craving intensity, and snack consumption at five times per day. Results showed that 86 percent of reported snacks were high-caloric, with chocolate-containing foods being the most often reported snacks. Individuals with high FCQ-T-r scores (high trait food cravers, HCs) thought more often about high-calorie than low-calorie snacks whereas no differences were found in individuals with low FCQ-T-r scores (low trait food cravers, LCs). Further, the relationship between craving intensity and snack-related thoughts was stronger in HCs than in LCs. Higher craving intensity was associated with more consumption of snacks and again this relationship was stronger in HCs than in LCs. Finally, more snack-related thoughts were related to more frequent consumption of snacks, independent of trait food craving. Thus, HCs are more prone to think about high-calorie snacks in their daily lives and to consume more snack foods when they experience intense cravings, which might be indicative of a heightened responding towards high-calorie foods. Thus, trait-level differences as well as snack-related thoughts should be targeted in dietary interventions. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Environmental concerns, growing public pressure and regulatory measures are changing the way people do business around the world. Consumers and shareholders are increasingly demanding environmentally-friendly ceramic products, as well as transparency in the environmental performance of the companies. Since its creation in 1995, The Eco-Management and Audit Scheme (EMAS is a voluntary tool recognized as the most reliable environmental management system available in EU for organizations to evaluate, improve and report companies’ environmental performance. Regulation (EC No 1221/2009 of the European Parliament and of the Council, known as EMAS III or Global EMAS, allows organizations outside EU to participate, making EMAS more attractive for ceramic companies that usually export. Ceramic companies that implement EMAS, achieve marketplace advantages and improve company image, as well as adding credibility and confidence with customers, stakeholders and public authorities. They also benefit of environmental legislation relief and other advantages as exception of financial insurance obligation included in new Environmental Responsibility legislation.

    This paper studies the effect of a high-Z extra mural absorber (EMA) to improve the spatial resolution of a plastic (polystyrene) scintillating fiber array for 14.1 MeV fusion neutron imaging. Crosstalk induced by recoil protons was studied, and platinum (Pt) was selected as EMA material, because of its excellent ability to suppress the recoil protons penetrating the fibers. Three common fiber arrays (cylindrical scintillating fibers in square and hexagonal packing arrangements and square scintillating fibers) were simulated using the Monte Carlo method for evaluating the effect of Pt-EMA in improving spatial resolution. It is found that the resolution of the 100 μm square fiber array can be improved from 1.7 to 3.4 lp/mm by using 10- μm-thick Pt-EMA; comparatively, using an array with thinner square fibers (50 μm) only obtains a resolution of 2.1 lp/mm. The packing fraction decreases with the increase of EMA thickness. Our results recommend the use of 10 μm Pt-EMA for the square and the cylindrical (hexagonal packing) scintillating fiber arrays with fibers of 50-200 μm in the cross-sectional dimension. Besides, the dead-zone material should be replaced by high-Z material for the hexagonal packing cylindrical fiber array with fibers of 50-200 μm in diameter. Tungsten (W) and gold (Au) are also used as EMA in the three fiber arrays as a comparison. The simulation results show that W can be used at a lower cost, and Au does not have any advantages in cost and resolution improvement.

    Stress and emotions alter eating behavior in several ways: While experiencing negative or positive emotions typically leads to increased food intake, stress may result in either over- or undereating. Several participant characteristics, like gender, BMI and restrained, emotional, or external eating styles seem to influence these relationships. Thus far, most research relied on experimental laboratory studies, thereby reducing the complexity of real-life eating episodes. The aim of the present study was to delineate the effects of stress, negative and positive emotions on two key facets of eating behavior, namely taste- and hunger-based eating, in daily life using ecological momentary assessment (EMA). Furthermore, the already mentioned individual differences as well as time pressure during eating, an important but unstudied construct in EMA studies, were examined. Fifty-nine participants completed 10days of signal-contingent sampling and data were analyzed using multilevel modeling. Results revealed that higher stress led to decreased taste-eating which is in line with physiological stress-models. Time pressure during eating resulted in less taste- and more hunger-eating. In line with previous research, stronger positive emotions went along with increased taste-eating. Emotional eating style moderated the relationship between negative emotions and taste-eating as well as hunger-eating. BMI moderated the relationship between negative as well as positive emotions and hunger-eating. These findings emphasize the importance of individual differences for understanding eating behavior in daily life. Experienced time pressure may be an important aspect for future EMA eating studies.

Additionally, we addressed the hypothesis that the M. tridactyla population studied has low levels of polymorphism and high levels of inbreeding and relatedness and that animals with overlapping home range are highly related. All five microsatellite loci displayed low levels of polymorphism and of expected and observed heterozygosity. The low level of polymorphism and high inbreeding showed by the population studied may be the outcome of high mortality and reduction in population size due to recurrent fire events in the Emas National Park, as reported in 1994. The reduction in population size may have led to a higher frequency of mating between closely related animals, augmented by the isolation of the population in the park because of the expansion of agricultural land and fragmentation of the Cerrado environment. The natural history of M. tridactyla and the phylopatric (sex-biased dispersal behavior of females should increase the effects of isolation and bottlenecking, decreasing gene flow and increasing inbreeding. However, the low levels of polymorphism found in this population may simply be due to the natural history and evolution of M. tridactyla as reported for other species. The genetic structure and dynamics of this population needs to be investigated more profoundly in order to provide sound data for the design of conservation strategies for M. tridactyla in the Emas National Park.

    Maternal diet during pregnancy might influence the development of childhood allergic disorders. The aim of the present study was to evaluate the impact of Mediterranean diet (MD) adherence during pregnancy on wheeze and eczema in the first year of life in two population-based mother-child cohorts in Spain and Greece. We studied 1771 mother-newborn pairs from the Spanish multi-centre 'INMA' (INfancia y Medio Ambiente) study (Gipuzkoa, Sabadell and Valencia) and 745 pairs from the 'RHEA' study in Crete, Greece. The symptoms of wheeze and eczema were based on the criteria of the International Study of Asthma and Allergies in Childhood. Maternal diet during pregnancy was assessed by FFQ and MD adherence was evaluated through an a priori score. Multivariate log-binomial regression models were used to adjust for several confounders in each cohort and summary estimates were obtained by a meta-analysis. MD adherence was not associated with the risk of wheeze and eczema in any cohort, and similar results were identified in the meta-analysis approach. High meat intake (relative risk (RR) 1·22, 95 % CI 1·00, 1·49) and 'processed' meat intake (RR 1·18, 95 % CI 1·02, 1·37) during pregnancy were associated with an increased risk of wheeze in the first year of life, while a high intake of dairy products was significantly associated with a decreased risk of infantile wheeze (RR 0·83, 95 % CI 0·72, 0·96). The results of the present study show that high meat intake during pregnancy may increase the risk of wheeze in the first year of life, while a high intake of dairy products may decrease it.

    Poor perinatal maternal mental health has been linked with negative outcomes on early child development; however, the importance of maternal personality has been neglected thus far. We aimed to examine the effects of antenatal and postnatal maternal mental health, including assessment of maternal personality characteristics, on child neuropsychological and behavioral development at preschool years in a population based mother-child cohort (Rhea Study) in Crete, Greece. Self-reported measures of maternal depression (EPDS), trait anxiety (STAI-Trait) and personality traits (EPQ-R) were assessed in a sample of 288 women at 28-32 weeks of gestation. A larger sample of 642 mothers completed the EPDS scale at 8 weeks postpartum. Children's neuropsychological (MSCA) and behavioral (ADHDT and SDQ) development were assessed at 4 years of age. Linear regression analyses were used to estimate the associations between the exposures and outcomes of interest after adjustment for potential confounders. Regarding child neuropsychological development, increased postnatal depressive symptoms were associated with child's perceptual performance, whereas increased maternal psychoticism was linked with child's motor ability at 4 years of age. Furthermore, elevated levels of maternal depression during pregnancy and postpartum, and the predisposing personality characteristics of trait anxiety and neuroticism, were associated with children's behavioral difficulties. A clinical diagnostic instrument for maternal mental health was not used and assessment of children's behavior was based on maternal report. These findings suggest that poor perinatal maternal mental health and an adverse personality profile may be associated with impaired child neuropsychological and behavioral development at preschool years.

    Epithelial membrane antigen (EMA or MUC1) is a heavily glycosylated, type I transmembrane glycoprotein commonly expressed by epithelial cells of duct organs. It has been shown to be aberrantly glycosylated in several diseases including cancer. Protein sequence based annotation and analysis of glycosylation profile of glycoproteins by robust computational and comprehensive algorithms provides possible insights to the mechanism(s) of anomalous glycosylation. In present report, by using a number of bioinformatics applications we studied EMA/MUC1 and explored its trans-membrane structural domain sequence that is widely subjected to glycosylation. Exploration of different extracellular motifs led to prediction of N and O-linked glycosylation target sites. Based on the putative O-linked target sites, glycosylated moieties and pathways were envisaged. Furthermore, Protein network analysis demonstrated physical interaction of EMA with a number of proteins and confirmed its functional involvement in cell growth and proliferation pathways. Gene Ontology analysis suggested an involvement of EMA in a number of functions including signal transduction, protein binding, processing and transport along with glycosylation. Thus, present study explored potential of bioinformatics prediction approach in analyzing glycosylation, co-expression and interaction patterns of EMA/MUC1 glycoprotein.

    The 1836/93 EMAS is the European regulation on environmental management and auditing scheme. Its aim is to answer the precise requirements of a standard for the management of the environmental impacts of industrial activities. The ISO 14001 standard defines the requirements of an environmental management policy at the international scale. The aim of this study is to make a statement of the enforcement of the ISO 14001 and EMAS environmental management systems in France in terms of results and with respect to the help provided by public authorities. The following aspects are analyzed successively: the aim of the study (context, global goal, hypotheses, cost-benefit analysis, qualitative appraisal); the methodological aspects (selection of sites, sectoral distribution, geographical, legal and financial aspects, data collection, analysis and synthesis); the motivation of companies (sectoral analysis, business aspects, reduction of operation costs, personnel motivation); the objectives of the environmental management system (conformability analysis, environmental goals, effluents, soil pollution, energy and water conservation, wastes, consumption of raw materials, noise and other pollutants); economical aspects (cost, personnel training, audits, benefits, minimization of environmental impacts, reduction of energy, water and materials consumption); cost-benefit evaluation; environmental efficiency of the environmental management system; attitude of other companies; comparison with other European countries; synthesis and proposals.

    Full Text Available The objective of this paper is to analyze the influence of the sources of motivation that lead companies to adopt a global standard of the Environmental Management System and the barriers found in the process, on the perceived benefits of the implementation and certification of the standard. To achieve the objectives proposed, primary data were collected using a survey questionnaire that was administered to a representative sample of companies certified as EMAS-Eco-Management and Audit Scheme of the Autonomous Community of Galicia (sample of 114 of the 255 companies. An extensive review of the academic literature published on ISO 14001 and EMAS about motivations, barriers and benefits was carried out in order to establish the working hypotheses that are analyzed using structural equation models as the statistical tool. The findings of this study show that the motivations positively affect the benefits derived from implementation, noting that the internal motivations (related to efficiency; improved performance, productivity and profitability have a stronger influence on the benefits than the external motivations (related to stakeholders’ social pressure. In addition, the motivations also affect the perceived barriers, and these affect the benefits negatively, i.e., the higher the barriers encountered, the lower the perceived benefits. The results obtained allow us to identify important implications for managers, which will help them establish management strategies in the field of environmental management.

    Full Text Available EMA can be defined as the identification, collection, estimation, analysis, internal reporting, and use of materials and energy flow information, environmental cost information, and other cost information for both conventional and environmental decision-making within an organization. Thus EMA incorporates and integrates two of the three building blocks of sustainable development – environment and economics – as they relate to an organization’s internal decision-making. EMA is a relatively new tool in environmental management. Decades ago environmental costs were very low, so it seemed wise to include them in the overhead account for simplicity and convenience. Recently there has been a steep rise in all environmental costs, including energy and water prices as well as liabilities.

    This essay argues that Chang-rae Lee’s novel A Gesture Life exemplifies both the conceptual gains and the potential pitfalls of current Asian American literature’s transnationalism. The first section of the essay discusses the interlocking of psychoanalytic theory and political philosophy, specifically Freud’s uncanny and Arendt’s banality of evil, in Lee’s portrait of the psychology of criminal repression. The second section juxtaposes Lee’s novel against real-life comfort women’s survivor testimonies to probe broader questions of historical memory, politicized historiography, and the modes of circulation and authority in contemporary international comfort women discourse. The final section, which recontextualizes Lee’s novel within current debates in Asian and Asian American Studies, argues against a paradigm of alterity vis-à-vis the comfort women and proposes instead a transnational aesthetic premised on the human.

    Breast feeding duration has been associated with improved cognitive development in children. However, few population-based prospective studies have evaluated dose-response relationships of breastfeeding duration with language and motor development at early ages, and results are discrepant. The study uses data from the prospective mother-child cohort ('Rhea' study) in Crete, Greece. 540 mother-child pairs were included in the present analysis. Information about parental and child characteristics and breastfeeding practices was obtained by interview-administered questionnaires. Trained psychologists assessed cognitive, language and motor development by using the Bayley Scales of Infant Toddler Development (3rd edition) at the age of 18 months. Duration of breast feeding was linearly positively associated with all the Bayley scales, except of gross motor. The association persisted after adjustment for potential confounders with an increase of 0.28 points in the scale of cognitive development (β=0.28; 95% CI 0.01 to 0.55), 0.29 points in the scale of receptive communication (β=0.29; 95% CI 0.04 to 0.54), 0.30 points in the scale of expressive communication (β=0.30; 95% CI 0.04 to 0.57) and 0.29 points in the scale of fine motor development (β=0.29; 95% CI 0.02 to 0.56) per accumulated month of breast feeding. Children who were breast fed longer than 6 months had a 4.44-point increase in the scale of fine motor development (β=4.44; 95% CI 0.06 to 8.82) compared with those never breast fed. Longer duration of breast feeding was associated with increased scores in cognitive, language and motor development at 18 months of age, independently from a wide range of parental and infant characteristics. Additional longitudinal studies and trials are needed to confirm these results. Published by the BMJ Publishing Group Limited.

    EMAS (Environmental Management and Audit Scheme) introduced by the Regulation n. 1836/93, is one of the new tools activated by the European Community to overcome the old `Command and Control` philosophy and adopt an approaching policy in the `Moral suasion` logic. It is based on the sharing out of the responsibility, dialogue and action agreed upon by the concerned parties on the basis of impartial and reliable information. EMAS has voluntary character and presents many analogies with ISO 14.000 international system with which a deeper integration is being attempted for a revision of the Regulation. In the frame of present national and international situation, the report shows the recording path of an EMAS site and the experiences achieved up to now particularly by ENEA. [Italiano] L`EMAS (Environmental Management and Audit Scheme), introdotto con il Rergolamento n. 1836/93, rappresenta uno dei nuovi strumenti che la Comunita` Europea ha attivato per superare la vecchia logica del `Command and Control` (Imponi e Sorveglia) e passare ad una nuova filosofia di approccio nella logica della `Moral suasion` (persuasione morale) per un rapporto basato sulla ripartizione delle responsabilita` attraverso un dialogo e un`azione concertata tra le parti interessate sulla base di un`informazione obiettiva ed affidabile. Lo strumento EMAS ha carattere di volontarieta` e presenta profonde analogie con il sistema internazionale ISO 14.000 con il quale si sta tentando, a livello di revisione del Regolamento EMAS, una integrazione piu` profonda.

    This paper summarises the results of EM analyses for ITER in-vessel components, such as blanket modules, backplate and divertor modules. In the ITER design the following two disruption scenarios are taken into account: centered or radial disruption, and vertical displacement event (VDE). Eddy currents and forces due to plasma disruption were calculated using the 3D shell element code EDDYCUFF and the 3D solid element code EMAS. The plasma motion and current decay used in the EM analysis was supplied by 2-D axisymmetric plasma equilibrium codes, TSC and MAXFEA. (authors)

    The purpose of this work is to characterize the role of the financial institutions in achieving sustainable development meaning a process of development which leaves at least the same amount of capital, natural and man-made, to future generations as current generations have access to. This makes it clear that sustainable development is about capital allocation and thus should be at the core of financial markets activity. On a more practical level the different ways banks affect environment are analyzed: as investors - supplying the investments with environmental perspective; as lenders - developing new financial products to encourage sustainable development; as valuers - estimating risks and opportunities in project-financing; as powerful stake holders - as shareholders and lenders they can exercise considerable influence over companies; - as polluters - while not dirty industries, financial institutions do consume natural resources. By the study of these environmental aspects it comes out that bank should introduce the environmental variable in internal management to reduce their own impacts and, above all, in credit assessment, in development of new financial products to encourage businesses to invest in duty technologies and adopt environmental management systems (EMAS, ISO 14001), and in helping small shareholders in deciding how to invest their own money, for example advising Green funds.

    The research-and-development project aims at gathering, systemising and assessing the entirety as well as selected points concerning the promotion of participation to EMAS by the use of incentives and awards regulations as practised in the member states of the European Union. It intends, furthermore, to make proposals for measures and regulations to improve the situation. This research centres on the impact of environment-policy or environmental-law instruments as regulating incentives and awards. The survey involves three different, interlocking methodical approaches: the jurisprudential analysis and interpretation method, secondary analysis and empirical components in the form of polls. The concepts of 'incentive' and 'reward' are used as synonyms. Binding commitments, explicitly promising advantages to organisations applying EMAS are considered to be 'incentives and awards regulations'. Incentives and rewards regulations have - in part - already become an integral part of the EMAS Regulation in domestic Federal law, mainly in the shape of the EMAS-Privilege Regulation (EMAS-PrivilegV). The interpretation of the incentive and rewards regulations in the member states reveals striking similarities: there, one concentrates mainly on environmental information, reduction of fees as well as promotional programmes as instrument categories. Compared to this, the categories of environmental obligations and official handling still experienced a clear, though weaker, preference. Planning instruments, official handling, environmental agreements and most of economic instruments are either not used, marginally used, or little used. As it turns out, the exemplary registration of the public sector, in particular, strongly needs to be upgraded. The instrument of 'official handling' still contains valuable potential for the promotion of EMAS. There is still plenty of room for improvement in the use of the EMAS logo, in spite of the very

    Full Text Available Polymer electrolytes based on 90 wt% of methyl methacrylate and 10 wt% of ethyl methacrylate (90MMA-co-10EMA incorporating different weight ratios of sodium iodide were prepared using the solution casting method. The complexation between salt and copolymer host has been investigated using Fourier transform infrared spectroscopy. The ionic conductivity and thermal stability of the electrolytes were measured using impedance spectroscopy and differential scanning calorimetry, respectively. Scanning electron microscopy was used to study the morphology of the polymer electrolytes. The ionic conductivity and glass transition temperature increased up to 20 wt% of sodium iodide (5.19 × 10−6 S·cm−1 and decreased with the further addition of salt concentration, because of the crosslinked effect. The morphology behavior of the highest conducting sample also showed smaller pores compared to the other concentration. The total ionic transference number proved that this system was mainly due to ions, and the electrochemical stability window was up to 2.5 V, which is suitable for a dye-sensitized solar cell application. This sample was then tested in a dye-sensitized solar cell and exhibited an efficiency of 0.62%.

    This study was conducted in October 1998 and November 1999 in the Emas National Park (131,868 ha), a savanna-type cerrado region situated in the far south of Goias State, Brazil, near the geographic center of South America (15 degrees -23 degrees S; 45 degrees -55 degrees W). Animals were captured with the aid of nets and anesthetized (15 mg/kg ketamine + 1 mg/kg xylasine) in order to collect ticks for identification and to establish laboratory colonies. They included giant anteaters (Myrmecophaga tridactyla) (n = 4) and yellow armadillos (Euphractus sexcinctus) (n = 6). Free-living ticks (larvae, nymphs, and adults) were collected from the field by using a 1 x 2-m flannel cloth. Free-living ticks were identified as Amblyomma sp., A. cajennense, and A. triste. Adult ticks collected from anteaters were identified as Amblyomma cajennense and A. nodosum and from armadillos as A. pseudoconcolor and A. nodosum. The relevance of these host-tick relationships to possible mechanisms underlying emergence of tick-borne pathogens of importance to public health is discussed.

    The process leading to a regulatory outcome is guided by factors both related and unrelated to the data package, defined in this analysis as 'formal and informal factors', respectively. The aim of this qualitative study was to analyse which formal and informal factors drive the decision-making process of the European Medicines Agency (EMA) and Food and Drug Administration (FDA) regulators with regard to anticancer drugs, using in-depth semi-structured interviews with regulators of the two agencies. In line with the theory and practice of qualitative research, no set sample size was defined a priori. Respondent enrolment continued until saturation and redundancy were reached. Data were collected through means of in-depth semi-structured interviews conducted either in a face-to-face setting or via Skype(®) with each regulator. The interviews were audio-recorded and verbatim transcribed. The analysis was manually carried out on the transcribed text. Data were independently coded and categorized by two researchers. Interpretation of the findings emerged through a process of triangulation between the two. Seven EMA and six FDA regulators, who had extensive experience with making decisions about anticancer medicines, were interviewed between April and June 2012. There is an open dialogue between the FDA and EMA, with the two moving closer and exchanging information, not opinions. Differences in decision-making between the agencies may be due to a different evaluation of end points. Different interaction modalities with industry and patients represent an additional source of divergence with a potential impact on decision-making. The key message of our respondents was that the agencies manage uncertainty in a different way: unlike the EMA, the FDA has a prevailing attitude to take risks in order to guarantee quicker access to new treatments. Although formal factors are the main drivers for regulatory decisions, the influence of informal factors plays an important role in

    The societal costs of disasters around the world are continuing to increase and Pacific Island countries are considered some of the most vulnerable.This is primarily due to a combination of high hazard exposure coupled with a range of social,economic,physical,and political vulnerabilities.This article contributes to the growing body of work that aims to understand the causal factors of disaster vulnerability,but with a specific focus on small island developing states.The article first develops a framework for understanding disaster vulnerability,drawing on extensive literature and the well-established Methods for the Improvement of Vulnerability in Europe (MOVE) framework,and second,applies this adapted framework using empirically-derived data from fieldwork on Emae Island,Vanuatu to provide a working understanding of the causal elements of disaster vulnerability.Drawn from a significant body of scholarship at the time,the MOVE framework was primarily developed as a heuristic tool in which disaster vulnerability is considered to be a function of exposure,susceptibility (socially,economically,physically,culturally,environmentally,institutionally),and a lack of resilience.We posit that this adapted framework for small islands should also include historical susceptibility,and we prefer livelihood resilience (as capabilities,social capital,knowledge,participation,and human rights) over lack of resilience.We maintain that understanding disaster vulnerability holistically,which is inclusive of both strengths and drawbacks,is crucial to ensure that limited resources can target the causal factors that produce vulnerability and help safeguard and improve livelihoods in both the short and long term.

    Solar pasteurization is effective in reducing the level of indicator organisms in stored rainwater to within drinking water standards. However, Legionella spp. were detected at temperatures exceeding the recommended pasteurization temperatures using polymerase chain reaction assays. The aim of the current study was thus to apply EMA quantitative polymerase chain reaction (EMA-qPCR) to determine whether the Legionella spp. detected were intact cells and therefore possibly viable at pasteurization temperatures >70°C. The BacTiter-Glo™ Microbial Cell Viability Assay was also used to detect the presence of ATP in the tested samples, as ATP indicates the presence of metabolically active cells. Chemical analysis also indicated that all anions and cations were within the respective drinking water guidelines, with the exception of iron (mean: 186.76 μg/L) and aluminium (mean: 188.13 μg/L), which were detected in the pasteurized tank water samples at levels exceeding recommended guidelines. The BacTiter-Glo™ Microbial Cell Viability Assay indicated the presence of viable cells for all pasteurized temperatures tested, with the percentage of ATP (in the form of relative light units) decreasing with increasing temperature [70-79°C (96.7%); 80- 89°C (99.2%); 90-95°C (99.7%)]. EMA-qPCR then indicated that while solar pasteurization significantly reduced (p0.05) in the mean copy numbers was detected with an increase in the pasteurization temperature, with 6 × 10(3) genomic copies/mL DNA sample obtained at 95°C. As intact Legionella cells were detected in the pasteurized tank water samples, quantitative microbial risk assessment studies need to be conducted to determine the potential health risk associated with using the water for domestic purposes.

    To identify cell-surface molecules that mediate interactions between neurons and their environment during neural development, we used monoclonal antibody techniques to define a developmentally regulated antigen in the central nervous system of the mouse. The antibody we produced (2A1) immunolabels cells throughout the central nervous system; we analyzed its distribution in the developing cerebral cortex, where it is expressed on cells very soon after they complete mitosis and leave the periventricular proliferative zone. Expression continues into adult life. The antibody also labels the epithelium of the choroid plexus and the renal proximal tubules, but does not label neurons of the peripheral nervous system in the dorsal root ganglia. In dissociated cell culture of embryonic cerebral cortex, 2A1 labels the surface of neurons but not glia. Immunolabeling of neurons in tissue culture is particularly prominent on the edge of growth cones, including filopodia and the leading edge of lamellipodia, when observed with either immunofluorescence or freeze-etch immunoelectron microscopy. Immunopurification with 2A1 of a CHAPS-extracted membrane preparation from brains of neonatal mice produces a broad (32-36 kD) electrophoretic band and a less prominent 70 kD band that are sensitive to N-glycosidase but not endoglycosidase H. Thus the 2A1 antibody recognizes a developmentally regulated, neuronal cell surface glycoprotein (or glycoproteins) with complex N-linked oligosaccharide side chains. We have termed the glycoprotein antigen EMA because of its prominence on the edge membrane of growth cones. EMA is similar to the M6 antigen (Lagenaur et al: J. Neurobiol. 23:71-88, 1992) in apparent molecular weight, distribution in tissue sections, and immunoreactivity on Western blots, suggesting that the two antigens are similar or identical. Expression of EMA is a very early manifestation of neuronal differentiation; its distribution on growth cones suggests a role in mediating the

    Micro-, small-, and medium-sized enterprises (SMEs) have been considered as key players who can bring innovative medicinal products and/or technologies into the field. However, they may need much regulatory/scientific supports to provide their products, technologies, or services to the market in a timely way. Both the Pharmaceuticals and Medical Devices Agency (PMDA) and the European Medicines Agency (EMA), regulatory authorities for medicinal products in Japan and the EU, respectively, have prepared supportive measures for SMEs from the early phase of product/technology development to the postmarketing phase. With respect to supports for SMEs, both agencies have provided similar SME-specific supportive activities, including routine administrative assistance, consultations about product development strategy from an early phase, as well as specific regulatory/scientific issues and fee incentives. In addition, there is a system to register SME status in the EU, which can be a tool for regulators to know how much potential SME-driven activities have and with whom they should communicate to provide necessary supports. Furthermore, as new technologies and novel products from SMEs are not limited to the region where they are developed, close communication about these topics between the PMDA and the EMA will contribute to advancing patients' access to necessary medicinal products.

    Full Text Available Abstract A grid-trapping (CMR Method of the Wood Mouse (<em>A. sylvaticusem> resident population was carried on three sample areas in a Mediterranean Oak-wood (Bosco della Ficuzza, Palermo. Fifty live traps were settled on a 0.5 ha grid at each sample area and permitted to calculate the Petersen-Lincoln Index (modified by Chapman. The relative density in the typical oak-wooded area (20.4/ha is highest than in the ecotonal and gazed sample area (12.6/ha. Analysis of ground permanence shows that the population in the wooded area is more dinamic than in the other area; in the former area a large number of new captures occurs, in fact, each month and the monthly variation of the relative density has a different trend. These results would confirm the indirect data coming from pellets analysis showing how in Sicily the highest densities occur in woodlands (oak-woods, as well as beech forests. The ecological niche of the Wood Mouse, due also to the apparent lack of <em>A. flavicollisem>, is thus larger than in peninsular Italy and continental Europe. The reproductive season lasts over the whole year but the birth peaks occurred in summer (1988 and late fall (1989. Population each year stabilizes for overwintering and later (Jun-Nov is almost completely renowed. Moreover, differences in sex and age trappability in relation to the two mode1 of traps utilized and a low mortality due to the cautions in handling the trapped mice, were recorded.

    In the present work, the rare earth elements concentration (REE) in plant leaves of the species Solanum lycocarpum from `Cerrado de Emas`, Pirassununga, Sao Paulo, and the soil where they have grown up, was determined by using instrumental neutron activation analysis. The obtained values for most of the light REE (La, Ce, Nd) were higher than the reference values for REE in plants. These results suggest that the light REE are more available in the soil than the heavy REE. The concentration of REE in the plant and the soil were normalized to chondrite contents, showing in the soil diagram a negative anomaly for the concentration of Eu and a positive anomaly for the concentration of Ce, which were not observed in the plant diagram.

    Full Text Available Benjamin Graham, also known as the “father of value investing” proposed that investment in the stock exchange can be a safe endeavor while receiving gains that outperform the market if the investor makes carefully thought out purchases. This study aims to determine if the use of some of Benjamin Graham’s stock selection criteria is able to generate returns that are significantly greater than the returns in the stock exchange of Malaysia, particularly, the comprehensive FTSE Bursa Malaysia EMAS Index. This study collected secondary data regarding fundamentals of companies listed in the FTSE Bursa Malaysia EMAS Index from the year 2000 to 2009. Five criteria were set up in this research based on one or a combination of price-to-earnings ratio, price-to-book value, current ratio and dividend yield. The listed companies were screened using those criteria. An equally weighted portfolio was created using the screened companies and their one-year and two-year returns calculated. The returns were compared to the market return. Hypotheses of this research were tested using t-test statistic to determine the significance of the data. This research found that most of the screening criteria used generated returns that were higher than the market return in almost every year they were tested in. Benjamin Graham’s stock selection criteria although have been conceived over 80 years ago is still applicable today in the Malaysian market. Further research can be conducted with different criteria with varying holding periods and in different markets.

However, FISH detection is costly and time consuming. Thus, we established nuclei microarray with extracted intact nuclei from paraffin embedded breast cancer tissues for FISH detection. The nuclei microarray FISH (NMFISH technology serves as a useful platform for analyzing <em>HER2em> gene/chromosome 17 centromere ratio. We examined <em>HER2em> gene status in 152 cases of invasive ductal carcinomas of the breast that were resected surgically with FISH and NMFISH. <em>HER2em> gene amplification status was classified according to the guidelines of the American Society of Clinical Oncology and College of American Pathologists (ASCO/CAP. Comparison of the cut-off values for <em>HER2em>/chromosome 17 centromere copy number ratio obtained by NMFISH and FISH showed that there was almost perfect agreement between the two methods (κ coefficient 0.920. The results of the two methods were almost consistent for the evaluation of <em>HER2em> gene counts. The present study proved that NMFISH is comparable with FISH for evaluating <em>HER2em> gene status. The use of nuclei microarray technology is highly efficient, time and reagent conserving and inexpensive.

The primary aim of this series of workshops is to assess the state-of-the-art and reliability of microbeam analysis techniques. The workshops also provide a forum where students and young scientists starting out on careers in microbeam analysis can meet and discuss with the established experts. The workshops have a very distinct format comprising invited plenary lectures by internationally recognized experts, poster presentations by the participants and round table discussions on the key topics led by specialists in the field. For this workshop EMAS invited speakers on the following topics: EPMA, EBSD, fast energy-dispersive X-ray spectroscopy, three-dimensional microanalysis, and micro-and nanoanalysis in the natural resources industry. The continuing relevance of the EMAS workshops and the high regard in which they are held internationally can be seen from the fact that 69 posters from 16 countries were on display at the meeting and that the participants came from as far away as Japan and the USA. A number of participants with posters were invited to give short oral presentations of their work in two dedicated sessions. As at previous workshops there was also a special oral session for young scientists. Small cash prizes were awarded for the three best posters and for the best oral presentation by a young scientist.

    Full Text Available Satellite cell activity is necessary for postnatal skeletal muscle growth. Severe phosphate (PO4 deficiency can alter satellite cell activity, however the role of neonatal PO4 nutrition on satellite cell biology remains obscure. Twenty-one piglets (1 day of age, 1.8 ± 0.2 kg BW were pair-fed liquid diets that were either PO4 adequate (0.9% total P, supra-adequate (1.2% total P in PO4 requirement or deficient (0.7% total P in PO4 content for 12 days. Body weight was recorded daily and blood samples collected every 6 days. At day 12, pigs were orally dosed with BrdU and 12 h later, satellite cells were isolated. Satellite cells were also cultured <em>in vitroem> for 7 days to determine if PO4 nutrition alters their ability to proceed through their myogenic lineage. Dietary PO4 deficiency resulted in reduced (<em>P> < 0.05 sera PO4 and parathyroid hormone (PTH concentrations, while supra-adequate dietary PO4 improved (<em>P> < 0.05 feed conversion efficiency as compared to the PO4 adequate group. <em>In vivoem> satellite cell proliferation was reduced (<em>P> < 0.05 among the PO4 deficient pigs, and these cells had altered <em>in vitroem> expression of markers of myogenic progression. Further work to better understand early nutritional programming of satellite cells and the potential benefits of emphasizing early PO4 nutrition for future lean growth potential is warranted.

Meskipun telah menyediakan lapangan kerja untuk masyarakat lokal, kegiatan tersebut menurunkan kualitas lingkungan, khususnya sungai, karena penggunaan merkuri. Dalam hal ini penggunaan merkuri dalam proses pengambilan emas murni dari batuan telah mempengaruhi air sungai sehingga memiliki kandungan 0,002-1 mg/l Hg;0,05 mg/l Pb; 0,4 mg/l Cu and 28,39 mg/l Fe. Berdasarkan peraturan -pemerintah No. 822001 tentang pengelolaan kualitas air dan air irigasi, konstituen metal tersebut telah melebihi baku mutu air. Penggunaan mineral zeolite sebagai adsorben pada proses penambangan emas tradisional menunjukkan bahwa zeolit dengan ukuran 80- 100 mesh dapat mengurangi kadar hg sehingga masuk ke dalam baku mutu air.   ABSTRACT The gold mine activity of people in jendi village has been conducted since 1993. Even though this activity provide job for the local people. It will degrade the environmental quality especially river, because of Mercury use. The use of Mercury in the process to extract natural gold from concentrate of rock mill affects river water because it contains 0.002-1 mg/l Hg; 0,05 mg/l Pb; 0,4 mg/l Cu and 28,39 mg/l Fe. Based on the Government Regulation No. 82/2001 Concerning the Management of Water Quality and Irrigation water, those metal constituents have already been above the water standard quality. Using mineral zeolite as adsorbent on the traditional gold processing showed that zeolite with size 80-100 mesh could reduce the content of Hg, Pb, Cu, and Fe, which fall within the water standard quality.

    Patients with adrenal insufficiency have impaired health-related quality of life (QoL). The dual-release hydrocortisone preparation, Plenadren, has been developed to mimic the physiological cortisol release more closely than conventional hydrocortisone treatment. Plenadren has been shown to improve QoL, in particular fatigue, in patients with primary adrenal insufficiency. However, the effect has not been investigated in patients with secondary adrenal insufficiency; furthermore, no study has taken the diurnal variation of fatigue into account. To assess diurnal variations, it is necessary to use repeated daily measurements, such as ecological momentary assessments (EMAs). This study aims to evaluate EMAs of fatigue as outcome in future large-scale randomised clinical trials. The PlenadrEMA trial is an investigator-initiated open-label switch pilot trial of the effect of Plenadren versus conventional hydrocortisone on fatigue in patients with secondary adrenal insufficiency. The trial will include 30 participants. After 5 weeks on their usual hydrocortisone treatment, patients will be shifted to Plenadren for 16 weeks. Fatigue will be assessed using momentary versions of the Multidimensional Fatigue Inventory (MFI-20). Items will be administered to participants via a smartphone application four times daily during 20 days. Assessments will be performed before treatment shift and repeated after 12.5 weeks on Plenadren. The study will identify the best suited outcome for future randomised clinical trials, and in addition, estimate the variability and difference in fatigue between the two treatments to perform power calculations. The trial will be conducted in accordance with the Declaration of Helsinki and has been approved by the Regional Scientific Ethical Committee in Copenhagen (ID: H-1-2014-073). All patients will receive written and verbal information about the trial and will give informed consent before enrolment. Findings will be published in peer

Most of the fish (80%) were counted not in the fish ladder itself, but in two adjacent spillways at its left, perhaps due to the comparatively increased flow as they are narrower than the ladder. The bulk of the migration occurred in September/October. We inspected the degree of injury of the fish in order to examine the hypothesis that larger fish are less injured, however no conclusion was reached. The degree of injury varied between different points and in different months of the year.

    Previous bi-spectral imager retrievals of cloud optical thickness (COT) and effective particle radius (CER) based on the Nakajima and King (1990) approach, such as those of the operational MODIS cloud optical property retrieval product (MOD06), have typically paired a non-absorbing visible or near-infrared wavelength, sensitive to COT, with an absorbing shortwave or midwave infrared wavelength sensitive to CER. However, in practice it is only necessary to select two spectral channels that exhibit a strong contrast in cloud particle absorption. Here it is shown, using eMAS observations obtained during NASAs SEAC4RS field campaign, that selecting two absorbing wavelength channels within the broader 1.88 micron water vapor absorption band, namely the 1.83 and 1.93 micron channels that have sufficient differences in ice crystal single scattering albedo, can yield COT and CER retrievals for thin to moderately thick single-layer cirrus that are reasonably consistent with other solar and IR imager-based and lidar-based retrievals. A distinct advantage of this channel selection for cirrus cloud retrievals is that the below cloud water vapor absorption minimizes the surface contribution to measured cloudy TOA reflectance, in particular compared to the solar window channels used in heritage retrievals such as MOD06. This reduces retrieval uncertainty resulting from errors in the surface reflectance assumption, as well as reduces the frequency of retrieval failures for thin cirrus clouds.

    Full Text Available A water-soluble polysaccharide (BEBP was extracted from <em>Boletus edulis em>Bull using hot water extraction followed by ethanol precipitation. The polysaccharide BEBP was further purified by chromatography on a DEAE-cellulose column, giving three major polysaccharide fractions termed BEBP-1, BEBP-2 and BEBP-3. In the next experiment, the average molecular weight (Mw, IR and monosaccharide compositional analysis of the three polysaccharide fractions were determined. The evaluation of antioxidant activities both <em>in vitroem> and <em>in vivo em>suggested that BEBP-3 had good potential antioxidant activity, and should be explored as a novel potential antioxidant.

Buscamos, em primeiro lugar, uma definição estética do que seria um retrato cinematográfico, sempre em tensão com os critérios formais e padrões estilísticos que historicamente constituíram o retrato pictórico. Em seguida, relacionamos essa questão com a importância que se deu à representação do close-up de rosto nas primeiras décadas do cinema, quando foi atribuído aos filmes um papel inédito no estudo da fisionomia e da expressão facial. Por fim, apresentamos exemplos de autorretratos na pintura e no cinema para expor a forma como a autorrepresentação põe em crise as noções de subjetividade e identidade em que a definição clássica do retrato se apoiava.

    Full Text Available In this communication we discuss the development of ionophore based nanosensors for the detection and monitoring of histamine levels <em>in vivoem>. This approach is based on the use of an amine-reactive, broad spectrum ionophore which is capable of recognizing and binding to histamine. We pair this ionophore with our already established nanosensor platform, and demonstrate <em>in vitroem> and <em>in vivoem> monitoring of histamine levels. This approach enables capturing rapid kinetics of histamine after injection, which are more difficult to measure with standard approaches such as blood sampling, especially on small research models. The coupling together of <em>in vivoem> nanosensors with ionophores such as nonactin provide a way to generate nanosensors for novel targets without the difficult process of designing and synthesizing novel ionophores.

    2012-08-01

    Full Text Available Ascidians have developed multiple defensive strategies mostly related to physical, nutritional or chemical properties of the tunic. One of such is chemical defense based on secondary metabolites. We analyzed a series of colonial Antarctic ascidians from deep-water collections belonging to the genera <em>Aplidium> and <em>Synoicum> to evaluate the incidence of organic deterrents and their variability. The ether fractions from 15 samples including specimens of the species <em>A.> <em>falklandicum>, <em>A.> <em>fuegiense>, <em>A.> <em>meridianum>, <em>A.> <em>millari> and <em>S.> <em>adareanum> were subjected to feeding assays towards two relevant sympatric predators: the starfish <em>Odontaster> <em>validus>, and the amphipod <em>Cheirimedon> <em>femoratus>. All samples revealed repellency. Nonetheless, some colonies concentrated defensive chemicals in internal body-regions rather than in the tunic. Four ascidian-derived meroterpenoids, rossinones B and the three derivatives 2,3-epoxy-rossinone B, 3-epi-rossinone B, 5,6-epoxy-rossinone B, and the indole alkaloids meridianins A–G, along with other minoritary meridianin compounds were isolated from several samples. Some purified metabolites were tested in feeding assays exhibiting potent unpalatabilities, thus revealing their role in predation avoidance. Ascidian extracts and purified compound-fractions were further assessed in antibacterial tests against a marine Antarctic bacterium. Only the meridianins showed inhibition activity, demonstrating a multifunctional defensive role. According to their occurrence in nature and within our colonial specimens, the possible origin of both types of metabolites is discussed.

    Full Text Available This study was designed to investigate the DNA-methylation status of <em>E>-cadherin (<em>CDH1em> and <em>H>-cadherin (<em>CDH13em> in serum samples of cervical cancer patients and control patients with no malignant diseases and to evaluate the clinical utility of these markers. DNA-methylation status of <em>CDH1em> and <em>CDH13em> was analyzed by means of MethyLight-technology in serum samples from 49 cervical cancer patients and 40 patients with diseases other than cancer. To compare this methylation analysis with another technique, we analyzed the samples with a denaturing high performance liquid chromatography (DHPLC PCR-method. The specificity and sensitivity of <em>CDH1em> DNA-methylation measured by MethyLight was 75% and 55%, and for <em>CDH13em> DNA-methylation 95% and 10%. We identified a specificity of 92.5% and a sensitivity of only 27% for the <em>CDH1em> DHPLC-PCR analysis. Multivariate analysis showed that serum <em>CDH1em> methylation-positive patients had a 7.8-fold risk for death (95% CI: 2.2–27.7; <em>p> = 0.001 and a 92.8-fold risk for relapse (95% CI: 3.9–2207.1; <em>p> = 0.005. We concluded that the serological detection of <em>CDH1em> and <em>CDH13em> DNA-hypermethylation is not an ideal diagnostic tool due to low diagnostic specificity and sensitivity. However, it was validated that <em>CDH1em> methylation analysis in serum samples may be of potential use as a prognostic marker for cervical cancer patients.

Synthetic seeds were produced using <em>in vitroem> proliferated microshoots upon complexation of 3% sodium alginate prepared in Llyod and McCown woody plant medium (WPM and 100 mM calcium chloride. Re-growth ability of encapsulated nodal segments was evaluated after storage at 4 °C for 0, 1, 2, 4, 6 and 8 weeks and compared with non-encapsulated buds. Effects of different media <em>viz>; Murashige and Skoog medium; Lloyd and McCown woody Plant medium, Gamborg’s B5 medium and Schenk and Hildebrandt medium was also investigated for conversion into plantlets. The maximum frequency of conversion into plantlets from encapsulated nodal segments stored at 4 °C for 4 weeks was achieved on woody plant medium supplement with 5.0 μM BA and 1.0 μM NAA. Rooting in plantlets was achieved in half-strength Murashige and Skoog liquid medium containing 0.5 μM indole-3-acetic acid (IAA on filter paper bridges. Plantlets obtained from stored synseeds were hardened, established successfully <em>ex vitroem> and were morphologically similar to each other as well as their mother plant. The genetic fidelity of <em>Rauvolfia em>clones raised from synthetic seeds following four weeks of storage at 4 °C were assessed by using random amplified polymorphic<em> em>DNA (RAPD and inter-simple sequence repeat<em> em>(ISSR markers. All the RAPD and ISSR profiles from generated plantlets were monomorphic and comparable<em> em>to the mother plant, which confirms the genetic<em> em>stability among the clones. This synseed protocol could be useful for establishing a particular system for conservation, short-term storage and production of genetically identical and stable plants before it is released for commercial purposes.

  6. The EM Earthquake Precursor

    2013-12-01

    Many attempts have been made to determine a sound forecasting method regarding earthquakes and warn the public in turn. Presently, the animal kingdom leads the precursor list alluding to a transmission related source. By applying the animal-based model to an electromagnetic (EM) wave model, various hypotheses were formed, but the most interesting one required the use of a magnetometer with a differing design and geometry. To date, numerous, high-end magnetometers have been in use in close proximity to fault zones for potential earthquake forecasting; however, something is still amiss. The problem still resides with what exactly is forecastable and the investigating direction of EM. After the 1989 Loma Prieta Earthquake, American earthquake investigators predetermined magnetometer use and a minimum earthquake magnitude necessary for EM detection. This action was set in motion, due to the extensive damage incurred and public outrage concerning earthquake forecasting; however, the magnetometers employed, grounded or buried, are completely subject to static and electric fields and have yet to correlate to an identifiable precursor. Secondly, there is neither a networked array for finding any epicentral locations, nor have there been any attempts to find even one. This methodology needs dismissal, because it is overly complicated, subject to continuous change, and provides no response time. As for the minimum magnitude threshold, which was set at M5, this is simply higher than what modern technological advances have gained. Detection can now be achieved at approximately M1, which greatly improves forecasting chances. A propagating precursor has now been detected in both the field and laboratory. Field antenna testing conducted outside the NE Texas town of Timpson in February, 2013, detected three strong EM sources along with numerous weaker signals. The antenna had mobility, and observations were noted for recurrence, duration, and frequency response. Next, two

    Full Text Available The mottled skate, <em>Raja pulchraem>, is an economically valuable fish. However, due to a severe population decline, it is listed as a vulnerable species by the International Union for Conservation of Nature. To analyze its genetic structure and diversity, microsatellite markers were developed using 454 pyrosequencing. A total of 17,033 reads containing dinucleotide microsatellite repeat units (mean, 487 base pairs were identified from 453,549 reads. Among 32 loci containing more than nine repeat units, 20 primer sets (62% produced strong PCR products, of which 14 were polymorphic. In an analysis of 60 individuals from two <em>R. pulchra em>populations, the number of alleles per locus ranged from 1–10, and the mean allelic richness was 4.7. No linkage disequilibrium was found between any pair of loci, indicating that the markers were independent. The Hardy–Weinberg equilibrium test showed significant deviation in two of the 28 single-loci after sequential Bonferroni’s correction. Using 11 primer sets, cross-species amplification was demonstrated in nine related species from four families within two classes. Among the 11 loci amplified from three other <em>Rajidae> family species; three loci were polymorphic. A monomorphic locus was amplified in all three <em>Rajidae> family species and the <em>Dasyatidae> family. Two <em>Rajidae> polymorphic loci amplified monomorphic target DNAs in four species belonging to the Carcharhiniformes class, and another was polymorphic in two Carcharhiniformes species.

Dessa forma, o objetivo desse trabalho foi realizar o levantamento da população de ácaros associados às plantas ornamentais no município de Arapiraca-AL, em função dos diversos problemas acarretados por essa espécie. O levantamento foi realizado entre os meses de abril a março, através de amostragens mensais de folhas coletadas da parte basal, intermediária e apical de plantas existentes em praças e jardins. Foram coletados 55 ácaros pertencentes à ordem Prostigmata em 20 famílias de plantas. As plantas com as maiores riquezas de ácaros foram as Coleus blumei L. e Bxuxus sempervirens L., que apresentaram 65% dos valores amostrais. Analisando-se as coletas realizadas, pode-se observar que houve uma maior incidência populacional de ácaros na coleta do mês de maio, cuja percentagem foi de 36% de ácaros levantados, sendo que no levantamento dos dados amostrais de março a percentagem encontrada foi de 14%, nas amostragens dos meses de abril e junho, a percentagem amostrada dos dados foi de 22 e 28%, respectivamente. O estudo do levantamento de ácaros em plantas ornamentais permitiu observar a relação entre ácaros e a relação com a planta hospedeira, facilitando posteriormente um estudo mais aprofundado sobre plantas hospedeiras, e pode-se observar que em períodos chuvosos ocorre uma menor incidência populacional.

Gold’s price is allegedly influenced by another factors such as US Dollar, oil’s price, inflation rate, and stock exchange so that its model is not only affected by its value. The aim of this research is to determine the best forecasting model and influencing factors to gold’s price. This research reviews the univariate modeling as a benchmark and comparison to the multivariate one. Univariate time series is modeled using the ARIMA model which indicates that the fluctuation of the gold prices are following the white noise. Gold’s multivariate modeling is built using the Vector Error Correction Model with oil’s price, US Dollar and Dow Jones indices, and inflation rate as its predictors. Research’s result shows that the VECM model has been able to model the gold’s price well and all factors investigated are influencing gold’s price. US Dollar and oil’s price are negatively correlated with gold’s price as the inflation rate is positively correlated. Dow Jones Index is positively correlated with gold’s price only at its first two periods

Pupae, newly-emerged adults and foraging adults were sampled from honey bee colonies at one site in S. Texas, USA. <em>Varroa>‑infested bees displayed elevated titer of Deformed Wing Virus (DWV, suggestive of depressed capacity to limit viral replication. Expression of genes coding three anti-microbial peptides (<em>defensin1, abaecin, hymenoptaecinem> was either not significantly different between <em>Varroa>-infested and uninfested bees or was significantly elevated in <em>Varroa>-infested bees, varying with sampling date and bee developmental age. The effect of <em>Varroa> on nutritional indices of the bees was complex, with protein, triglyceride, glycogen and sugar levels strongly influenced by life-stage of the bee and individual colony. Protein content was depressed and free amino acid content elevated in <em>Varroa>-infested pupae, suggesting that protein synthesis, and consequently growth, may be limited in these insects. No simple relationship between the values of nutritional and immune-related indices was observed, and colony-scale effects were indicated by the reduced weight of pupae in colonies with high <em>Varroa> abundance, irrespective of whether the individual pupa bore <em>Varroa>.

    Full Text Available A case of sacrococcygeal chordoma in a 9-year-old boy is presented. The symptoms at presentation were pain in both legs and sacrococcygeal region for the last two years that increased in the last four weeks irradiating mainly to the left leg. X-ray and CT scan examinations of the lumbar region revealed an expansive process in the coccygeal region with multiple calcifications and a partially eroded coccyx. There was no invasion of the retroperitoneum and regional lymph nodes. A biopsy was performed and showed cords and nests of cells with large cytoplasm, sometimes vacuolated, nuclei with moderate pleomorphism and clumped chromatin. Immunohistochemistry with avidin-biotin peroxidase technique showed positivity for CK, S-100 protein, CEA, vimentin and to EMA. Chordomas are a distinctly uncommon neoplasm in the first two decades of life, specially in the sacrococcygeal region. They have an aggressive behavior. Treatment of choice is complete resection.Os autores apresentam um caso de cordoma sacroccígeo em um menino de 9 anos de idade. O paciente foi admitido no hospital com história de dor na região sacral e nos membros inferiores com dois anos de evolução, piorando nas últimas quatro semanas. O exame físico revelou atrofia muscular moderada em ambos os membros inferiores, diminuição do reflexo patelar e presença do sinal de Lasègue à esquerda. Os exames de imagem da região lombar mostraram um processo expansivo na região sacrococcígea com erosão parcial do coccix e focos de calcificação, sem evidência de metástases para linfonodos regionais. Foi realizada biópsia diagnóstica que mostrou neoplasia formada por cordões e ninhos de células de citoplasma amplo, por vezes vacuolado, com núcleos moderadamente pleomórficos com cromatina grumosa.

    Full Text Available O índice de infecções pós-operatórias em pacientes neuro-cirúrgicos que receberam antibióticos profiláticos neste período foi comparado com o de pacientes que não receberam antibióticos. Infecções ocorreram em proporções significativamente maiores nos pacientes que receberam antibióticos, particularmente naqueles com afecções intracranianas graves; estas infecções foram graves e fatais na maioria dos casos. A administração de antibióticos profiláticos nestes pacientes não só foi incapaz de prevenir o aparecimento de infecções pós-operatórias, como aparentemente favoreceu o seu desenvolvimento.

    2014-05-01

    Many attempts have been made to determine a sound forecasting method regarding earthquakes and warn the public in turn. Presently, the animal kingdom leads the precursor list alluding to a transmission related source. By applying the animal-based model to an electromagnetic (EM) wave model, various hypotheses were formed, but the most interesting one required the use of a magnetometer with a differing design and geometry. To date, numerous, high-end magnetometers have been in use in close proximity to fault zones for potential earthquake forecasting; however, something is still amiss. The problem still resides with what exactly is forecastable and the investigating direction of EM. After a number of custom rock experiments, two hypotheses were formed which could answer the EM wave model. The first hypothesis concerned a sufficient and continuous electron movement either by surface or penetrative flow, and the second regarded a novel approach to radio transmission. Electron flow along fracture surfaces was determined to be inadequate in creating strong EM fields, because rock has a very high electrical resistance making it a high quality insulator. Penetrative flow could not be corroborated as well, because it was discovered that rock was absorbing and confining electrons to a very thin skin depth. Radio wave transmission and detection worked with every single test administered. This hypothesis was reviewed for propagating, long-wave generation with sufficient amplitude, and the capability of penetrating solid rock. Additionally, fracture spaces, either air or ion-filled, can facilitate this concept from great depths and allow for surficial detection. A few propagating precursor signals have been detected in the field occurring with associated phases using custom-built loop antennae. Field testing was conducted in Southern California from 2006-2011, and outside the NE Texas town of Timpson in February, 2013. The antennae have mobility and observations were noted for

    Full Text Available Foi realizado um estudo de casos de osteoporose em caprinos provenientes de uma propriedade na área de abrangência do LPV-UFSM, determinando a epidemiologia, o quadro clínico-patológico e discutindo os prováveis mecanismos patogenéticos. Cinco cabras, fêmeas, SRD, de seis meses a seis anos de idade foram afetadas. As cabras eram mantidas em campo nativo, sem suplementação com ração e sob superlotação. Os principais sinais clínicos foram emagrecimento, dificuldade de locomoção e permanência em decúbito por longos períodos. As principais alterações macroscópicas nos ossos examinados foram vistas nas superfícies de corte e caracterizavam-se por depleção do osso esponjoso (porosidade e redução acentuada da espessura do osso cortical. Havia também marcada atrofia serosa da gordura da medula óssea. Microscopicamente, nas regiões avaliadas (úmero proximal, rádio distal, fêmur distal, tíbia proximal e corpos das vértebras lombares foi observada redução moderada a acentuada do número e da espessura das trabéculas ósseas nas epífises e metáfises dos ossos longos e nos corpos vertebrais. Os achados clínico-patológicos indicaram que a osteoporose observada provavelmente foi causada pela desnutrição. As alterações ósseas (diminuição no número e na espessura das trabéculas do osso esponjoso sugerem que ambos os mecanismos, má formação óssea e reabsorção óssea aumentada, contribuíram para a ocorrência de osteoporose nos caprinos deste estudo.

    Full Text Available Cellulose synthase (CESA, which is an essential catalyst for the generation of plant cell wall biomass, is mainly encoded by the <em>CesA> gene family that contains ten or more members. In this study; four full-length cDNAs encoding CESA were isolated from<em> Betula platyphyllaem> Suk., which is an important timber species, using RT-PCR combined with the RACE method and were named as <em>BplCesA3em>, <em>−4em>,> −7 em>and> −8em>. These deduced CESAs contained the same typical domains and regions as their <em>Arabidopsis> homologs. The cDNA lengths differed among these four genes, as did the locations of the various protein domains inferred from the deduced amino acid sequences, which shared amino acid sequence identities ranging from only 63.8% to 70.5%. Real-time RT-PCR showed that all four <em>BplCesAs> were expressed at different levels in diverse tissues. Results indicated that BplCESA8 might be involved in secondary cell wall biosynthesis and floral development. BplCESA3 appeared in a unique expression pattern and was possibly involved in primary cell wall biosynthesis and seed development; it might also be related to the homogalacturonan synthesis. BplCESA7 and BplCESA4 may be related to the formation of a cellulose synthase complex and participate mainly in secondary cell wall biosynthesis. The extremely low expression abundance of the four BplCESAs in mature pollen suggested very little involvement of them in mature pollen formation in <em>Betula>. The distinct expression pattern of the four <em>BplCesAs> suggested they might participate in developments of various tissues and that they are possibly controlled by distinct mechanisms in <em>Betula.>

Todavia, também não são nada. Abelardo as chama de ‘quase coisas’ (<em style="mso-bidi-font-style: normal;">quasi resem>. No presente artigo, explicamos, primeiro, essas duas noções essenciais da lógica abelardiana, antes de tentar, em seguida, encontrar a fonte dessa metafísica particular. Em oposição a comentadores importantes da lógica de Abelardo, que estimam que haja uma forte influência platônica sobre essa concepção específica, defendemos antes, com apoio de textos significativos e de acordo com o nominalismo abelardiano, que a maior ascendência sobre a metafísica do nosso autor é a do estoicismo, sobretudo, antigo.In his work, Peter Abelard (1079-1142 highlights two metaphysical notions, which sustain his logical theory: the <em>status> and the <em>dictum propositionisem>, causing respectively both the imposition (<em>impositio> of universal terms and the thuth-value of propositions.

    A busca por estruturas em grandes escalas (aglomerados de galáxias, por exemplo) é um ativo tópico de pesquisas hoje em dia, pois a detecção de um único aglomerado em altos redshifts pode por vínculos fortes sobre os modelos cosmológicos. Neste projeto estamos fazendo uma busca de estruturas distantes em campos contendo pares de quasares próximos entre si em z Â3 0.9. Os pares de quasares foram extraídos do catálogo de Véron-Cetty & Véron (2001) e estão sendo observados com os telescópios: 2,2m da University of Hawaii (UH), 2,5m do Observatório de Las Campanas e com o GEMINI. Apresentamos aqui a análise preliminar de um par de quasares observado nos filtros i'(7800 Å) e z'(9500 Å) com o GEMINI. A cor (i'-z') mostrou-se útil para detectar objetos "early-type" em redshifts menores que 1.1. No estudo do par 131046+0006/J131055+0008, com redshift ~ 0.9, o uso deste método possibilitou a detecção de sete objetos candidatos a galáxias "early-type". Num mapa da distribuição projetada dos objetos para 22 escala. Um outro argumento em favor dessa hipótese é que eles obedecem uma relação do tipo Kormendy (raio equivalente X brilho superficial dentro desse raio), como a apresentada pelas galáxias elípticas em z = 0.

    Full Text Available An ultrasound and microwave assisted alternant extraction method (UMAE was applied for extracting dihydroquercetin (DHQ from <em>Larix gmeliniem>i> wood. This investigation was conducted using 60% ethanol as solvent, 1:12 solid to liquid ratio, and 3 h soaking time. The optimum treatment time was ultrasound 40 min, microwave 20 min, respectively, and the extraction was performed once. Under the optimized conditions, satisfactory extraction yield of the target analyte was obtained. Relative to ultrasound-assisted or microwave-assisted method, the proposed approach provides higher extraction yield. The effect of DHQ of different concentrations and synthetic antioxidants on oxidative stability in soy bean oil stored for 20 days at different temperatures (25 °C and 60 °C was compared. DHQ was more effective in restraining soy bean oil oxidation, and a dose-response relationship was observed. The antioxidant activity of DHQ was a little stronger than that of BHA and BHT. Soy bean oil supplemented with 0.08 mg/g DHQ exhibited favorable antioxidant effects and is preferable for effectively avoiding oxidation. The <em>L. gmeliniiem> wood samples before and after extraction were characterized by scanning electron microscopy. The results showed that the UMAE method is a simple and efficient technique for sample preparation.

O objetivo desta revisão foi coletar dados sobre tratamento da dor em queimados. CONTEÚDO: Foi feita revisão sobre os mecanismos de dor, avaliação do paciente com queimadura e o tratamento farmacológico e não farmacológico. CONCLUSÕES: O manejo da dor em pacientes vítimas de queimaduras ainda é um desafio por parte da equipe multiprofissional. A avaliação frequente e contínua da resposta apresentada pelo paciente é muito importante, tendo em vista os vários momentos por que passa o paciente internado em decorrência de uma queimadura, além de uma terapêutica combinada com medicações analgésicas e medidas não farmacológicas. Entender a complexidade de alterações fisiopatológicas, psicológicas e bioquímicas apresentadas por um paciente em tratamento de queimadura é o primeiro passo para alcançar o sucesso no seu manejo analgésico.

    Full Text Available Um museu participativo incentiva a que a experiência da visita seja criativa e pessoal. Facilita a participação biográfica do visitante - com a sua experiência, conhecimento e interesses. Muitas exposições, porém, não promovem esse envolvimento pessoal. Neste artigo apresentamos uma revisão da literatura que indicia que a mediação com objetos mediadores facilita o envolvimento pessoal, a construção de conhecimento e a criatividade. O problema teórico que colocamos é se os museus mais tradicionais se podem abrir à participação e, neste contexto, o nosso objetivo é perceber que papel podem ter os objetos mediadores nesse processo. Discutimos o recurso a objetos mediadores como forma de adicionar múltiplos níveis de relação e modos de ver, potencial que consideramos subaproveitado em muitos museus. Começamos por apresentar o museu como espaço potencialmente participativo, que convida a um envolvimento ativo e crítico – ativo, porque o visitante é desafiado a fazer coisas; crítico, porque é estimulado a pensar, optar, discutir e refletir. Discutimos depois diferentes formas de usar objetos mediadores para incentivar o visitante a um envolvimento com os artefactos, recorrendo à memória, experiência, conhecimento e sentimentos. A participação biográfica potencia o cruzamento entre o mundo interior do visitante e os artefactos e conteúdos do museu. Esse espaço de cruzamento - inbetween - é o espaço da construção de conhecimento. Apresentamos diversas formas de um museu, mesmo não sendo interativo, se tornar mais criativo e participativo, o que pode contribuir para uma mudança nas práticas dos museus, nomeadamente na montagem e remodelação de exposições permanentes.

    Full Text Available The thermal decomposition of Zn(II, Cd(II and Hg(II complexes of <em>N-ethyl-N>-phenyl and <em>N-butyl-N>-phenyl dithiocarbamates have been studied using thermogravimetric analysis (TGA and differential scanning calorimetry (DSC. The products of the decomposition, at two different temperatures, were further characterized by scanning electron microscopy (SEM and energy-dispersive X-ray spectroscopy (EDX. The results show that while the zinc and cadmium complexes undergo decomposition to form metal sulphides, and further undergo oxidation forming metal oxides as final products, the mercury complexes gave unstable volatiles as the final product.

    Full Text Available An apoptosis correlated molecule—protein Latcripin-1 of <em>Lentinula> edodesem> C91-3—was expressed and characterized in <em>Pichia pastorisem> GS115. The total RNA was obtained from <em>Lentinula edodesem> C91–3. According to the transcriptome, the full-length gene of Latcripin-1 was isolated with 3'-Full Rapid Amplification of cDNA Ends (RACE and 5'-Full RACE methods. The full-length gene was inserted into the secretory expression vector pPIC9K. The protein Latcripin-1 was expressed in <em>Pichia pastorisem> GS115 and analyzed by Sodium Dodecylsulfonate Polyacrylate Gel Electrophoresis (SDS-PAGE and Western blot. The Western blot showed that the protein was expressed successfully. The biological function of protein Latcripin-1 on A549 cells was studied with flow cytometry and the 3-(4,5-Dimethylthiazol-2-yl-2,5-Diphenyl-tetrazolium Bromide (MTT method. The toxic effect of protein Latcripin-1 was detected with the MTT method by co-culturing the characterized protein with chick embryo fibroblasts. The MTT assay results showed that there was a great difference between protein Latcripin-1 groups and the control group (<em>p em>< 0.05. There was no toxic effect of the characterized protein on chick embryo fibroblasts. The flow cytometry showed that there was a significant difference between the protein groups of interest and the control group according to apoptosis function (<em>p em>< 0.05. At the same time, cell ultrastructure observed by transmission electron microscopy supported the results of flow cytometry. The work demonstrates that protein Latcripin-1 can induce apoptosis of human lung cancer cells A549 and brings new insights into and advantages to finding anti-tumor proteins.

    Full Text Available The antibacterial activity and mechanism of two kinds of chitosan were investigated against twelve <em>Xanthomonas> strains recovered from <em>Euphorbia pulcherrimaem>. Results indicated that both chitosans markedly inhibited bacterial growth based on OD loss. Furthermore, the release of DNA and RNA from three selected strains was increased by both chitosans. However, the release of intracellular proteins was inhibited by both chitosans at different concentration and incubation times, except chitosan A at 0.1 mg/mL for 0.5 h incubation and 0.2 mg/mL for 2.0 h incubation increased the release of proteins, indicating the complexity of the interaction and cell membranes, which was affected by incubation time, bacterial species, chitosan type and concentration. Transmission electron microscopic observations revealed that chitosan caused changes in protoplast concentration and surface morphology. In some cells, the membranes and walls were badly distorted and disrupted, while other cells were enveloped by a thick and compact ribbon-like layer. The contrary influence on cell morphology may explain the differential effect in the release of material. In addition, scanning electron microscope and biofilm formation test revealed that both chitosans removed biofilm biomass. Overall, this study showed that membrane and biofilm play an important role in the antibacterial mechanism of chitosan.

Foram comparadas rações-teste ajustadas ou não para as quantidades de cloreto de colina e premix de vitaminas e microminerais em relação à ração-referência. Adotou-se o método tradicional de coleta total de excretas utilizando-se 360 pintos de corte machos e fêmeas da linhagem Ross de 15 a 23 dias de idade, alojados em baterias metálicas com bandejas coletoras de excretas. As aves foram distribuídas em esquema de blocos casualizados, de acordo com o andar das baterias, com dois tratamentos e 12 repetições de dez aves (cinco machos e cinco fêmeas. Em um tratamento, efetuou-se a substituição de 40% da ração-referência por farelo de soja, enquanto no outro, além dessa substituição, ajustaram-se as quantidades de cloreto de colina e dos premixes de vitaminas e microminerais com base na ração-referência. Os valores médios e os respectivos erros-padrão para EMA e EMAn (kcal/kg do farelo de soja, com base na matéria natural, foram 2.462±29,62 e 2.269±25,80 para ração ajustada e 2.353±26,18 e 2.191±23,88 para ração não ajustada. O ajuste das quantidades de cloreto de colina e do premix de vitaminas e microminerais na ração-teste propiciou maiores valores de EMA e EMAn do farelo de soja em relação à ração não-ajustada. É importante ajustar as quantidades de vitaminas e microminerais nas rações-teste em experimentos visando determinar a energia metabolizável de ingredientes para aves.The objective of this study was to evaluate the effects of vitamin and micromineral levels adjustment in the test diet on the total collection method for determination of apparent metabolizable energy (EMA and apparent metabolizable energy corrected by nitrogen retention

    Full Text Available Our goal was to identify the bacteria inhabiting the reproductive system of the female oriental fruit fly, <em>Bactrocera dorsalisem> (Hendel, and evaluate the chemotaxis of <em>B>. <em>dorsalis> to the metabolites produced by the bacteria. Based on 16S rRNA-based polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE, 18 operational taxonomic units (OTUs were assigned to the five bacterial classes <em>Betaproteobacteria>, <em>Alphaproteobacteria>, <em>Gammaproteobacteria>, <em>Bacilli> and <em>Actinobacteria>. Nine OTUs were assigned to <em>Gammaproteobacteria>, which was the most highly represented class. <em>Enterobacteriaceae> constituted the dominant family, and within this family, three genera and five species were identified, including <em>Enterobacter sakazakiiem>, <em>Klebsiella> <em>oxytoca>, <em>Klebsiella> <em>pneumoniae,> Raoultellaem> <em>terrigena em>and <em>Enterobacter> <em>amnigenus>. In this set, the first two species were the dominant components, and the latter three species were the minor ones. Finally, we found that the metabolites produced by <em>R.> terrigenaem>, <em>K. oxytocaem> and <em>K.> pneumoniae em>were attractive to the <em>B.> dorsalisem> adults, and in field studies, <em>B.> dorsalisem> adults were most attracted to <em>K.> oxytocaem>. Collectively, our results suggest that the female reproductive system plays an important role in the transfer of enterobacteria from the gut to fruit. Our data may prompt the development of a female-targeted population control strategy for this fly.

Nella penisola la specie presenta un areale discontinuo, il cui limite settentrionale è dato dal comune di Manciano (GR, sul versante tirrenico e da una linea che dalla provincia de L'Aquila arriva al Gargano. In Sicilia la distribuzione è relativamente continua anche in aree non protette. Dati genetici hanno permesso di confermare la presenza in Corsica. Al contrario, nell?Isola d'Elba, a seguito di estese ricerche, sono stati identificati solo esemplari di <em>L. europaeusem>. Nell?Italia peninsulare <em>L. corsicanusem> è spesso presente in simpatria con popolazioni di <em>L. europaeusem>, mentre in Sicilia la lepre europea non ha originato popolazioni stabili, nonostante l?immissione di molte migliaia di individui. La distribuzione ecologica di <em>L. corsicanusem> ed analisi ambientali specifiche, suggeriscono l?adattamento prevalente agli ambienti a clima mediterraneo, benché essa sia presente anche a quote elevate (> 1.500 m s.l.m.. Dati preliminari di abbondanza relativa hanno evidenziato una situazione diversificata tra la penisola e la Sicilia e tra aree a diverso regime di gestione; un confronto tra le aree protette ha evidenziato rispettivamente valori di 5,54 e 11,73 ind./km². La riduzione quali-quantitativa e la frammentazione dell?<em>habitat> delle lepri è un fenomeno potenzialmente pericoloso per la sopravvivenza delle popolazioni, determinando fenomeni di estinzione locale dovuti alle basse densità di popolazione, inducendo fenomeni di erosione della variabilità genetica e di riduzione della <em>fitness> degli individui. L?introduzione di <em>L. europaeusem> può costituire un importante fattore limitante sia per la possibile competizione

    In Colombia, citrus, tree tomato and mango crops are likely to suffer considerable losses from anthracnose caused by several <em>Colletotrichum> species, which were identified by the present study on infected organs of the three fruit crops, sampled in different regions of the country. Identification was based on their morphological and molecular characteristics, as well as on fungicide (benomyl and copper hydroxide sensitivity and pathogenicity tests. The latter assessed infectivity on both the original hosting crop and the other two crops (crossed infection, by putting the fungi in contact with organs taken from the three fruit crops. Molecular identification of the <em>Colletotrichum> species was carried out through amplification of rDNA ITS regions by means of <em>C. gloeosporioidesem> (CgInt and <em>C. acutatumem> (CaInt2 specific primer PCR combining the use of ITS4 universal primer. The results indicate that <em>C. acutatumem> is the infectious agent in Tahiti lime and tree tomato, and so is <em>C. gloeosporioidesem> in mango. Although <em>C. acutatumem> is the infectious agent in two diferent fruit species, the strains proved to be specific of their original hosts.

    Full Text Available In the Indian system of traditional medicine (Ayurveda it is recommended to consume <em>Ipomoea em>aquatica> to mitigate disorders like jaundice. In this study, the protective effects of ethanol extract of <em>I. aquaticaem> against liver damage were evaluated in thioacetamide (TAA-induced chronic hepatotoxicity in rats. There was no sign of toxicity in the acute toxicity study, in which Sprague-Dawley (SD rats were orally fed with <em>I. aquaticaem> (250 and 500 mg/kg for two months along with administration of TAA (i.p injection 200 mg/kg three times a week for two months. The results showed that the treatment of <em>I. aquaticaem> significantly lowered the TAA-induced serum levels of hepatic enzyme markers (ALP, ALT, AST, protein, albumin, bilirubin and prothrombin time. The hepatic content of activities and expressions SOD and CAT that were reduced by TAA were brought back to control levels by the plant extract supplement. Meanwhile, the rise in MDA level in the TAA receiving groups also were significantly reduced by <em>I. aquaticaem> treatment. Histopathology of hepatic tissues by H&E and Masson trichrome stains displayed that <em>I. aquaticaem> has reduced the incidence of liver lesions, including hepatic cells cloudy swelling, infiltration, hepatic necrosis, and fibrous connective tissue proliferation induced by TAA in rats. Therefore, the results of this study show that the protective effect of <em>I. aquaticaem> in TAA-induced liver damage might be contributed to its modulation on detoxification enzymes and its antioxidant and free radical scavenger effects. Moreover, it confirms a scientific basis for the traditional use of <em>I. aquaticaem> for the treatment of liver disorders.

    2005-01-01

    Full Text Available Competência no exercício da medicina depende de um processo evolutivo ao longo da vida do profissional, processo este fundamentado em eficiência, experiência e em princípios éticos. A eficiência depende da cultura médica, de habilidades técnicas e relacionamento interpessoal com o paciente. A experiência ao longo da vida vai refinando o médico, favorecendo o evolver do conhecimento e da sabedoria vivencial. Finalmente, a ética médica se fundamenta na justiça, compaixão e amor ao próximo. Didaticamente, distinguimos 3 fases da evolução profissional do médico: a infância profissional ou visão linear: o médico se restringe em geral ao atendimento da doença, negligenciando o doente. É quase exclusivamente técnico e tem percepção acanhada da medicina-arte. b Maturidade profissional ou visão humanística: resultado de evolução da personalidade, da cultura e da experiência do médico, agora voltado para o doente com sua doença. c Excelência profissional ou visão holística: estágio máximo que se pode alcançar, quando o médico vislumbra a si e ao seu cliente em todas suas dimensões integradas e atua como mestre, procurando despertar no paciente condições próprias de cura, oriundas de sua essência. Conclui-se que exercer medicina com competência significa desempenhar adequadamente a ciência e a arte médica.

    Complaints against Emergency Medical Services (EMS) agencies represent a concerning and potentially time-consuming problem for all involved in the delivery of prehospital emergency medical care. The objective of this study was to identify the source of complaints against an EMS system to help focus quality and performance improvement and customer service efforts. We conducted a retrospective review of complaints filed against a busy urban EMS agency over a 6-year period. All complaints were included, totaled by season and by year, and categorized by originator and nature of the complaint. A total of 286 complaints were registered during the 6-year period, with an average of 48 per year and 9.3 per 10,000 responses. The most common originators of complaints were patients (53%) followed by medical personnel (19%) and family members or friends (12%). Rude behavior accounted for 23% of the complaints registered, followed by technical skills (20%), transport problems (18%), and loss of belongings (13%). The identification of areas of dissatisfaction will allow focused quality and performance improvement programs directed at customer service and risk management.

  2. Adding large EM stack support

    Serial section electron microscopy (SSEM) image stacks generated using high throughput microscopy techniques are an integral tool for investigating brain connectivity and cell morphology. FIB or 3View scanning electron microscopes easily generate gigabytes of data. In order to produce analyzable 3D dataset from the imaged volumes, efficient and reliable image segmentation is crucial. Classical manual approaches to segmentation are time consuming and labour intensive. Semiautomatic seeded watershed segmentation algorithms, such as those implemented by ilastik image processing software, are a very powerful alternative, substantially speeding up segmentation times. We have used ilastik effectively for small EM stacks – on a laptop, no less; however, ilastik was unable to carve the large EM stacks we needed to segment because its memory requirements grew too large – even for the biggest workstations we had available. For this reason, we refactored the carving module of ilastik to scale it up to large EM stacks on large workstations, and tested its efficiency. We modified the carving module, building on existing blockwise processing functionality to process data in manageable chunks that can fit within RAM (main memory). We review this refactoring work, highlighting the software architecture, design choices, modifications, and issues encountered.

Está presente nos cinco continentes e é considerada endêmica em algumas regiões pela Organização Internacional de Epizootias (OIE. Pertence à lista de enfermidades notificáveis, que compreende as doenças transmissíveis de importância sócio-econômica e/ou em saúde-pública, cujo controle é necessário para o comércio internacional de animais e alimentos de origem animal. A importância da doença de Johne não se restringe somente aos prejuízos econômicos causados à indústria animal, mas também na possível participação do Map na íleocolite granulomatosa que afeta seres humanos, conhecida como doença de Crohn. No Brasil, a paratuberculose já foi descrita em diversas espécies de ruminantes e em vários estados. Embora os relatos naturais da enfermidade sejam pontuais, acredita-se na possibilidade da transmissão interespecífica e na disseminação do agente através da compra e venda de animais infectados. O objetivo deste artigo foi reunir as informações disponíveis referentes aos aspectos epidemiológicos, clínico-patológicos e laboratoriais da paratuberculose em bovinos, bubalinos, caprinos e ovinos no Brasil, e salientar a necessidade de implementação de medidas de controle sanitário da enfermidade no país, o que possibilitaria a melhoria da qualidade e valorização dos produtos de origem animal no mercado internacional.

    Full Text Available Ionic liquid based, ultrasound-assisted extraction was successfully applied to the extraction of phenolcarboxylic acids, carnosic acid and rosmarinic acid, from <em>Rosmarinus officinalisem>. Eight ionic liquids, with different cations and anions, were investigated in this work and [C8mim]Br was selected as the optimal solvent. Ultrasound extraction parameters, including soaking time, solid–liquid ratio, ultrasound power and time, and the number of extraction cycles, were discussed by single factor experiments and the main influence factors were optimized by response surface methodology. The proposed approach was demonstrated as having higher efficiency, shorter extraction time and as a new alternative for the extraction of carnosic acid and rosmarinic acid from <em>R. officinalisem>> em>compared with traditional reference extraction methods. Ionic liquids are considered to be green solvents, in the ultrasound-assisted extraction of key chemicals from medicinal plants, and show great potential.

    Full Text Available Abstract In small Mammals biogeography, available data are up to now by far too scanty for elucidate the distribution of a lot of taxa, especially with regard to the absence from a given area. In this respect, standardized quantitative sampling techniques, like Owl pellets analysis can enable not only to enhance faunistic knowledges, but also to estimate the actual absence probability of a given taxon "m", lacking from the diet of an individual raptor. For the last purpose, the relevant frequencies of "m" in the other ecologically similar sites of the same raptor species diets are averaged ($f_m$ : the relevant standard error (multiplicated by a coefficient, according to the desired degree of accuracy, in relation of the integral of probabilities subtracted ($overline{F}_m - a E$: then, the probability that a single specimen is not pertaining to "m" is obtained ($P_0 = 1 - F_m + a E$; lastly, the desiderate accuracy probability ($P_d$ is chosen. Now, "$N_d$" (the number of individuals of all prey species in a single site needed for obtain, with the desired probability, a specimen at least of "m" is obtained through $$N = frac{ln P_d}{ln P_0}$$ Obviously, every site-diet with more than "N" preyed individuals and without any "i" specimen is considered to be lacking of such taxon. A "usefulness index" for the above purposes is outlined and checked about three raptors. Some exanples about usefulness of the Owl pellet analysis method in biogeography are given, concerning <em>Tyto albaem> diets in peninsular Italy about: - <em>Sorex minutusem>, lacking in some quite insulated areas; - <em>Sorex araneusem> (sensu stricto, after GRAF et al., 1979, present also in lowland areas in Emilia-Romagna; - <em>Crocidura suaveolensem> and - <em>Suncus etruscusem>, present also in the southermost part of Calabria (Reggio province; - <em>Talpa caecaem>, present also in the Antiapennines of Latium (Cimini mounts; - <em>Talpa romanaem

Quarenta e dois porcento desses tumores eram de origem mesenquimal; 37% eram epiteliais; 14,5% eram derivados da crista neural; 5% eram tumores do cordão sexual; e 1,5 eram tumores originários do sistema nervoso periférico. O tumor mais frequentemente encontrado foi o linfoma (28% de todos os tumores, a maioria dos casos como parte do complexo leucose bovina enzoótica. O carcinoma de células escamosas foi o segundo tumor mais frequente (15% de todos os tumores. É chamada a atenção para a frequência desses tumores e para a sua importância no diagnóstico diferencial no abatedouro frigorífico entre eles e outras lesões importantes, incluindo as lesões granulomatosas da tuberculose. Houve uma ocorrência significativa do feocromocitoma adrenal (13% de todos os tumores. Papilomatose representou apenas 3% de todos os tumores. Como papilomas são comuns em bovinos, seu baixo número nesse estudo pode ser explicado pelo fato de que eles não são usualmente diagnosticados no exame post mortem (quando o couro já foi retirado da carcaça, mas sim no exame ante mortem, como ocorreu na maioria dos casos deste estudo. Tumores encontrados com menor frequência (cada um perfazendo entre 1.5 e 3% de todos os tumores incluíram adenocarcinoma apócrino misto da cauda, adenocarcinoma mamário, adenocarcinoma uterino, carcinoma de células renais, fibroma interdigital, hemangiossarcoma, leiomioma uterino, lipoma, lipossarcoma, mesotelioma, neurofibroma, tumor de células da granulosa, tumor estromal gastrointestinal, tumores hepáticos, tumores melanocíticos, e tumores pulmonares primários. Pretende-se que os resultados dessa pesquisa possam ajudar na identificação das lesões na inspeção oficial em matadouros frigoríficos.

    Full Text Available I due <em>Neomys> italiani sono ancora da chiarire dal punto di vista della loro caratterizzazione morfologica e ecologica. Il lavoro prende in considerazione un campione di entrambe le specie proveniente da habitat forestali dell?Appennino settentrionale per i quali sono stati identificati i principali parametri ambientali. Vengono quindi descritte la variabilità dei tratti morfologici delle due specie in aree localizzate nel Parco Nazionale Foreste Casentinesi, Monte Falterona e Campigna nell?Appennino tosco-romagnolo. Risultano di sicuro effetto discriminatorio la maschera facciale, il rapporto piede posteriore/coda e i caratteri cranici. Sulla base dei criteri identificativi si sono realizzate rilevazioni di misure corporee per le due specie e una comparazione degli habitat utilizzati. <em>N. fodiensem> appare unica specie nelle faggete-abetine e dominante nei castagneti, mentre nell?Ontaneta e nelle zone aperte e termofile si registra la sola presenza di <em>N. anomalusem>. Mancano entrambi nei prati cespugliati, nella pecceta e nella cerreta. I gradienti presenti sono quindi illustrati. Non appare una differenza altitudinale nel campione esaminato, posto in stazioni tra i 400 e i 1300 m, ma per entrambe vi sono maggiori riscontri nella fascia tra 700 e 850 m. Nell?analisi multivariata rispetto alle altre specie e alle variabili ambientali si riscontra sempre una discreta correlazione con la presenza di acqua di una certa ampiezza, che comunque è significativa solo per <em>N. fodiensem>, mentre risulta di interesse la positiva correlazione di <em>N. anomalusem> con <em>Apodemus sylvaticusem>.

    Full Text Available Abstract After the discovery of two different phonic types within the common pipistrelle (<em>Pipistrellus pipistrellusem>, mtDNA analysis confirmed the existence of two separate species named as common pipistrelle (<em>P. pipistrellusem> and soprano pipistrelle (<em>P. pygmaeusem>. The discrimination of these two cryptic species using external characters and measures has proved to be somewhat problematic. We examined two colonies of soprano pipistrelle from Donji Miholjac, Croatia. As a result, only two characters proved to be of help for field identification: wing venation (89% of cases and penis morphology and colour for males. The difference in length between the 2nd and 3rd phalanxes of the 3rd finger should be discarded as diagnostic trait between <em>P. pipistrellusem> and <em>P. pygmaeusem> in Croatia.

A seguito della descrizione di due differenti "tipi fonici" nel pipistrello nano (<em>Pipistrellus pipistrellusem> e della successiva conferma su basi genetiche dell'esistenza di due specie distinte, designate come pipistrello nano (<em>P. pipistrellusem> e pipistrello pigmeo (<em>P. pygmaeusem>, la distinzione delle due specie in base a caratteristiche morfologiche esterne si è dimostrata un problema di difficile soluzione. Sulla base delle caratteristiche distintive e delle differenze biometriche proposte da altri Autori, sono state esaminate due colonie di pipistrello pigmeo a Donji Miholjac, in Croazia. I risultati ottenuti evidenziano che, tra tutti i potenziali caratteri sinora proposti, solo due risultano utili per un'identificazione diretta sul campo: la venatura delle ali, risultata utile alla discriminazione nell'89% degli esemplari analizzati, e la colorazione e morfologia del pene nei maschi.

    Full Text Available The ability of macroencapsulated <em>Saccharomyces cerevisiae em>CBS8066<em> em>to withstand readily and not readily <em>in situem> convertible lignocellulose-derived inhibitors was investigated in anaerobic batch cultivations. It was shown that encapsulation increased the tolerance against readily convertible furan aldehyde inhibitors and to dilute acid spruce hydrolysate, but not to organic acid inhibitors that cannot be metabolized anaerobically. Gene expression analysis showed that the protective effect arising from the encapsulation is evident also on the transcriptome level, as the expression of the stress-related genes <em>YAP1em>, <em>ATR1em> and <em>FLR1em> was induced upon encapsulation. The transcript levels were increased due to encapsulation already in the medium without added inhibitors, indicating that the cells sensed low stress level arising from the encapsulation itself. We present a model, where the stress response is induced by nutrient limitation, that this helps the cells to cope with the increased stress added by a toxic medium, and that superficial cells in the capsules degrade convertible inhibitors, alleviating the inhibition for the cells deeper in the capsule.

  16. New hominin fossils from Kanapoi, Kenya, and the mosaic evolution of canine teeth in early hominins

    Directory of Open Access Journals (Sweden)

    J. Michael Plavcan

    2012-03-01

    Full Text Available Whilst reduced size, altered shape and diminished sexual dimorphism of the canine–premolar complex are diagnostic features of the hominin clade, little is known about the rate and timing of changes in canine size and shape in early hominins. The earliest <em>Australopithecus>, <em>Australopithecus anamensisem>, had canine crowns similar in size to those of its descendant <em>Australopithecus afarensisem>, but a single large root alveolus has suggested that this species may have had larger and more dimorphic canines than previously recognised. Here we present three new associated dentitions attributed to <em>A. anamensisem>, recently recovered from the type site of Kanapoi, Kenya, that provide evidence of canine evolution in early <em>Australopithecus>. These fossils include the largest mandibular canine root in the hominin fossil record. We demonstrate that, although canine crown height did not differ between these species, <em>A. anamensisem> had larger and more dimorphic roots, more like those of extant great apes and <em>Ardipithecus ramidusem>, than those of <em>A. afarensisem>. The canine and premolar occlusal shapes of <em>A. anamensisem> also resemble those of <em>Ar. ramidusem>, and are intermediary between extant great apes and <em>A. afarensisem>. <em>A. afarensisem> achieved <em>Homo>-like maxillary crown basal proportions without a reduction in crown height. Thus, canine crown size and dimorphism remained stable during the early evolution of <em>Australopithecus>, but mandibular root dimensions changed only later within the <em>A. anamensis–afarensisem> lineage, coincident with morphological changes in the canine–premolar complex. These observations suggest that selection on canine tooth crown height, shape and root dimensions was not coupled in early hominin evolution, and was not part of an integrated adaptive package.

    Full Text Available Os modos europeus e norte-americanos de entender como funciona o mundo dependem em grande parte do uso de dualismos - pares de conceitos, objetos ou sistemas de crenças opostos. Este ensaio enquadra especialmente três deles: sexo/gênero, natureza/criação e real/construído. Embora este texto verse sobre gênero, discuto regularmente o modo como as idéias de raça e gênero surgem a partir de supostos subjacentes sobre a natureza física do corpo. Entender como operam raça e gênero - em conjunto e independentemente - nos ajuda a compreender melhor como o social se torna corporificado.Euro-American ways of understanding how the world works depend heavily on the use of dualisms - pairs of opposing concepts, objects, or belief sytems. This text focuses especially on three of these: sex/gender, nature/nurture, and real/constructed. And although this text focuses on gender, I regularly discuss the ways in which the ideas of both race and gender emerge from underlying assumptions about the body's physical nature. Understanding how race and gender work - together and independently - help us learn more about how the social becomes embodied.

  1. PEG Enhancement for EM1 and EM2+ Missions

    Science.gov (United States)

    Von der Porten, Paul; Ahmad, Naeem; Hawkins, Matt

    2018-01-01

    NASA is currently building the Space Launch System (SLS) Block-1 launch vehicle for the Exploration Mission 1 (EM-1) test flight. The next evolution of SLS, the Block-1B Exploration Mission 2 (EM-2), is currently being designed. The Block-1 and Block-1B vehicles will use the Powered Explicit Guidance (PEG) algorithm. Due to the relatively low thrust-to-weight ratio of the Exploration Upper Stage (EUS), certain enhancements to the Block-1 PEG algorithm are needed to perform Block-1B missions. In order to accommodate mission design for EM-2 and beyond, PEG has been significantly improved since its use on the Space Shuttle program. The current version of PEG has the ability to switch to different targets during Core Stage (CS) or EUS flight, and can automatically reconfigure for a single Engine Out (EO) scenario, loss of communication with the Launch Abort System (LAS), and Inertial Navigation System (INS) failure. The Thrust Factor (TF) algorithm uses measured state information in addition to a priori parameters, providing PEG with an improved estimate of propulsion information. This provides robustness against unknown or undetected engine failures. A loft parameter input allows LAS jettison while maximizing payload mass. The current PEG algorithm is now able to handle various classes of missions with burn arcs much longer than were seen in the shuttle program. These missions include targeting a circular LEO orbit with a low-thrust, long-burn-duration upper stage, targeting a highly eccentric Trans-Lunar Injection (TLI) orbit, targeting a disposal orbit using the low-thrust Reaction Control System (RCS), and targeting a hyperbolic orbit. This paper will describe the design and implementation of the TF algorithm, the strategy to handle EO in various flight regimes, algorithms to cover off-nominal conditions, and other enhancements to the Block-1 PEG algorithm. This paper illustrates challenges posed by the Block-1B vehicle, and results show that the improved PEG

Os diagnósticos psiquiátricos destes pacientes variam: são neuróticos, apresentam transtornos de pesonalidade, são psicóticos e quase sempre com graves doenças secundárias: alcoolismo e toxicomania (Códigos Classificação Internacional de Doenças 295 a 299, 300. 301, 303 e 304. Propõe-se, à luz da compreensão psicanalítica destas pessoas, um tratamento psicoterápico breve, focal, com o auxílio de uma hospitalização em regime fechado. Para a avaliação dos resultados do método psicoterápico diádico, criaram-se critérios de cura coerentes com a proposta terapêutica, e equiparam-se estes critérios clínicos a valores numéricos. Utilizando 36 pacientes internados, verificou-se até que ponto eles alcançavam estes critérios. Cada paciente recebeu um escore - valor numérico - que expressou o seu desempenho durante o tratamento em regime de internação, e sua conduta pós-alta hospitalar, durante um seguimento médio de 21 meses. Estes 36 pacientes puderam ser divididos em dois grupos: os de evolução favorável (obtivemos 36,1% e os de evolução desfavorável. Por meio de uma amostra sistemática composta por 41 pacientes que não foram submetidos ao método, internados no mesmo período de tempo, no mesmo hospital, e pareados com nossa casuística, fêz-se uma comparação estatística entre os percentis obtidos nas evoluções dos dois grupos.

Diet composition of two family groups of alpine marmots was investigated in two areas of the Agordino’s Dolomites (Italian Alps in June-September 2001, by means of microscopic analysis of faeces and of direct observation of feeding activity. During the whole period of activity, a high consume of Angiosperms was confirmed, especially plants in flower; among them the “graminoids” seemed to play an important role only during the initial part of the active period. Generally vegetative parts predominated over flowers. The ingestion of animal preys was not confirmed by the analysis of droppings.

Diet showed low diversity considering the abundance of plant species in the surrounding environment. Food resources were probably used in relation to their easy digestibility, with a high content in proteins, sugar and water.

    Full text: 'Yudou No. 2' is a good soybean variety grown in the Honan Province. EMS was applied to seeds and valuable mutants were selected among the descendants. In a short period, several genetically stable strains were obtained. In the M 2 population, the early-maturing mutants were the most frequent, followed by short culm mutants. Other mutations altered leaf shape, grain size, habit of pod bearing, number of pods etc. One of the best strains is '86-180'. It is highly disease-resistant and ripens 19 days earlier than the original 'Yodou No. 2'. It bears more pods, although the seeds are a little bit smaller and is highly productive (4110kg/ha). Another good strain is '86-223'. It is also disease-resistant and highly productive (3390kg/ha). (author)

    Full text: 'Yudou No. 2' is a good soybean variety grown in the Honan Province. EMS was applied to seeds and valuable mutants were selected among the descendants. In a short period, several genetically stable strains were obtained. In the M{sub 2} population, the early-maturing mutants were the most frequent, followed by short culm mutants. Other mutations altered leaf shape, grain size, habit of pod bearing, number of pods etc. One of the best strains is '86-180'. It is highly disease-resistant and ripens 19 days earlier than the original 'Yodou No. 2'. It bears more pods, although the seeds are a little bit smaller and is highly productive (4110kg/ha). Another good strain is '86-223'. It is also disease-resistant and highly productive (3390kg/ha). (author)

    Full Text Available This study compared the usefulness of in vitro culture, PCR, and nested PCR for the diagnosis of Theileria equi in horses submitted to stress during exercise. Blood samples from 15 apparently healthy horses, previously conditioned to a high-speed equine treadmill, were taken prior to and after exercise. The animals were divided into two experimental groups: 30-day training schedule (G1 and 90-day training schedule (G2. Statistical analysis was performed using a chi-square test and kappa statistic was used in order to assess agreement. No significant difference was observed between samples collected at resting or after exercise. In G1, merozoites of T. equi were detected in the blood smears of four horses before in vitro culture, whereas 14 samples were positive, confirmed by culture. In G2, five and 11 horses were positive before and after culture, respectively. No PCR amplified product was observed in any of the tested animals although the PCR system based on the 16S rRNA gene of T. equi detected DNA in blood with an equivalent 8x10-5% parasitaemia. The nested PCR based on the T. equi merozoite antigen gene (EMA-1 allowed the visualization of amplified products in all the horses. Therefore, nested PCR should be considered as a means of detection of sub-clinical T. equi infections and in vitro culture could be used as a complement to other methods of diagnosis.Comparou-se a utilização do cultivo in vitro, PCR e nested PCR no diagnóstico de Theileria equi em eqüinos submetidos ao estresse induzido por exercícios.

    Peat soil is known as geotechnical problematic soil since it is the softest soil having highly organic and moisture content which led to high compressibility, low shear strength and long-term settlement. The aim of this study was to obtain the stabilized peat soils using the Effective Microorganisms (EM). The volume of EM added and mixed with peat soils varied with 2%, 4%, 6%, 8% and 10% and then were cured for 7, 14 and 21 days. The experiment was done for uncontrolled and controlled moisture content. Prior conducting the main experiments, the physical properties such as moisture content, liquid limit, specific gravity, and plastic limit etc. were measure for raw peat samples. The Unconfined Compressive Strength (UCS) test was performed followed by regression analysis to check the effect of EM on the soil strength. Obtained results have shown that the mix design for controlled moisture contents showed the promising improvement in their compressive strength. The peat soil samples with 10% of EM shows the highest increment in UCS value and the percentage of increments are in the range of 44% to 65% after curing for 21 days. The regression analysis of the EM with the soil compressive strength showed that in controlled moisture conditions, EM significantly improved the soil stability as the value of R2 ranged between 0.97 – 0.78. The results have indicated that the addition of EM in peat soils provides significant improving in the strength of the soil as well as the other engineering properties.

    Full Text Available A divalent cation-independent lectin—HOL-18, with cytotoxic activity against leukemia cells, was purified from a demosponge, <em>Halichondria okadaiem>. HOL-18 is a 72 kDa tetrameric lectin that consists of four non-covalently bonded 18 kDa subunits. Hemagglutination activity of the lectin was strongly inhibited by chitotriose (GlcNAcβ1-4GlcNAcβ1-4GlcNAc, fetuin and mucins from porcine stomach and bovine submaxillary gland. Lectin activity was stable at pH 4–12 and temperatures lower than 60 °C. Frontal affinity chromatography with 16 types of pyridylaminated oligosaccharides indicated that the lectin had an affinity for <em>N>-linked complex-type and sphingolipid-type oligosaccharides with <em>N>-acetylated hexosamines and neuramic acid at the non-reducing termini. The lectin killed Jurkat leukemia T cells and K562 erythroleukemia cells in a dose- and carbohydrate-dependent manner.

    Full Text Available Abstract <em>Rhinolophus euryaleem> and <em>R. mehelyiem> are morphologically very similar species and their distributions overlap extensively in the Mediterranean basin. We modelled their foraging behaviour using echolocation calls and wing morphology and, assuming niche segregation occurs between the two species, we explored how it is shaped by these factors. Resting frequency of echolocation calls was recorded and weight, forearm length, wing loading, aspect ratio and wing tip shape index were measured. <em>R. mehelyiem> showed a significantly higher resting frequency than <em>R. euryaleem>, but differences are deemed insufficient for dietary niche segregation. Weight and forearm length were significantly larger in <em>R. mehelyiem>. The higher values of aspect ratio and wing loading and a lower value of wing tip shape index in <em>R. melehyiem> restrict its flight manoeuvrability and agility. Therefore, the flight ability of <em>R. mehelyiem> may decrease as habitat complexity increases. Thus, the principal mechanism for resource partitioning seems to be based on differing habitat use arising from differences in wing morphology.

  18. Training for Defense? From Stochastic Traits to Synchrony in Giant Honey Bees (<em>Apis dorsataem>

    Full Text Available In Giant Honey Bees, abdomen flipping happens in a variety of contexts. It can be either synchronous or cascaded, such as in the collective defense traits of shimmering and rearing-up, or it can happen as single-agent behavior. Abdomen flipping is also involved in flickering behavior, which occurs regularly under quiescent colony state displaying singular or collective traits, with stochastic, and (semi- synchronized properties. It presumably acts via visual, mechanoceptive, and pheromonal pathways and its goals are still unknown. This study questions whether flickering is preliminary to shimmering which is subject of the <em>fs em>(flickering-shimmering-transition> hypothesis? We tested the respective prediction that trigger sites (<em>ts> at the nest surface (where shimmering waves had been generated show higher flickering activity than the alternative non-trigger sites (<em>nts>. We measured the flickering activity of <em>ts>- and <em>nts>-surface bees from two experimental nests, before and after the colony had been aroused by a dummy wasp. Arousal increased rate and intensity of the flickering activity of both <em>ts>- and <em>nts> cohorts (P < 0.05, whereby the flickering intensity of <em>ts>-bees were higher than that of <em>nts>-bees (P < 0.05. Under arousal, the colonies also increased the number of flickering-active <em>ts>- and <em>nts>-cohorts (P < 0.05. This provides evidence that cohorts which are specialist at launching shimmering waves are found across the quiescent nest zone. It also proves that arousal may reinforce the responsiveness of quiescent curtain bees for participating in shimmering, practically by recruiting additional trigger site bees for expanding repetition of rate and intensity of shimmering waves. This finding confirms the <em>fs-transition> hypothesis and constitutes evidence that flickering is part of a basal colony-intrinsic information system

    Full Text Available Environmental exposure to benzene occurs through cigarette smoke, unleaded gasoline and certain types of plastic. Benzene is converted to hematotoxic metabolites by the hepatic phase-I enzyme CYP2E1, and these metabolites are detoxified by the phase-II enzyme NQO1. The genes encoding these enzymes are highly polymorphic and studies of these polymorphisms have shown different pathogenic and prognostic features in various hematological malignancies. The potential role of different cytochrome p450 metabolizing enzymes in the pathogenesis of acute myeloid leukemia (AML in an area of active interest. In this study, we demonstrate aberrant CYP2E1 mRNA over-expression by quantitative real-time polymerase chain reaction in 11 cases of <em>de novoem> AML with inv(16; CBFβ-MYH11. CYP2E1 mRNA levels correlated with <em>CBFβ>-MYH11 em>transcript levels and with bone marrow blast counts in all cases. CYP2E1 over-expression correlated positively with NQO1 mRNA levels (R2 = 0.934, n = 7. By immunohistochemistry, CYP2E1 protein was more frequently expressed in AML with inv(16 compared with other types of AML (<em>p> < 0.001. We obtained serial bone marrow samples from two patients with AML with inv(16 before and after treatment. CYP2E1 mRNA expression levels decreased in parallel with <em>CBFβ>-MYH11 em>transcript levels and blast counts following chemotherapy. In contrast, CYP1A2 transcript levels did not change in either patient. This is the first study to demonstrate concurrent over-expression of CYP2E1 and NQO1 mRNA in AML with inv(16. These findings also suggest that a balance between CYP2E1 and NQO1 may be important in the pathogenesis of AML with inv(16.

    2018-03-01

    The concept of EM Drive has attracted much attention and groups of work have been conducted to prove or verify it, of which the published experimental outcome is criticized in great details while the theoretical foundation has not been discussed. The present essay investigates on the theoretical derivations of the net thrust in the "EM drive" and reveals the self-contradiction arising at the very start, when the law of conservation of momentum was utilized and opposed simultaneously.

    Full Text Available In traditional Chinese medicine, shikonin and its derivatives, has been used in East Asia for several years for the prevention and treatment of several diseases, including cancer. We previously identified that β,β-dimethylacrylshikonin (DA could inhibit hepatocellular carcinoma growth. In the present study, we investigated the inhibitory effects of DA on human colorectal cancer (CRC cell line HCT-116 <em>in vitroem> and <em>in vivoem>. A viability assay showed that DA could inhibit tumor cell growth in a time- and dose-dependent manner. Flow cytometry showed that DA blocks the cell cycle at G0/G1 phase. Western blotting results demonstrated that the induction of apoptosis by DA correlated with the induction of pro-apoptotic proteins Bax, and Bid, and a decrease in the expression of anti-apoptotic proteins Bcl-2 and Bcl-xl. Furthermore, treatment of HCT-116 bearing nude mice with DA significantly retarded the growth of xenografts. Consistent with the results <em>in vitroem>, the DA-mediated suppression of HCT-116 xenografts correlated with Bax and Bcl-2. Taken together, these results suggest that DA could be a novel and promising approach to the treatment of CRC.

    Full Text Available Relatou-se um caso clínico de dermatite multifatorial em cão, envolvendo Demodex canis, Sporothrix schenckii e bactérias dos gêneros Staphylococcus e Streptococcus. O animal, macho, da raça Pit Bull, com um ano e três meses de idade, apresentou lesões úmidas, hiperêmicas, descamativas e ulcerativas nas regiões do pescoço e do tórax. Exames laboratoriais confirmaram o diagnóstico de infecção concomitante por fungo, bactéria e parasito. A terapia antimicrobiana com moxidectina, itraconazol e amoxicilina foi efetiva, com remissão dos sinais clínicos após 30 dias de tratamento. Este relato salienta a importância do diagnóstico de certeza, que foi determinante para estabelecimento da terapêutica adequada e recuperação do animal.

  18. Monorquidismo em um equino marchador

    Directory of Open Access Journals (Sweden)

    Jéssica Fontana de Magalhães

    2015-06-01

    Full Text Available O monorquidismo é um quadro raramente descrito em equinos, que não apresenta descrições prévias na literatura nacional. Trata-se de um equino adulto brasileiro, com oito anos de idade, sem raça definida, porém com características de raças de origem nacional. Por abordagem inguinal do lado esquerdo, localizou-se a túnica vaginal intacta, que, aberta, continha a cauda de um epidídimo mal formado, o ducto deferente e um delgado pedículo vascular, mas sem indícios de testículo. Exames histológicos e hormonais confirmaram a ausência de tecido testicular. Conclui-se que os exames histológicos e hormonais são essenciais para o diagnóstico de monorquidismo que, apesar de raro, também pode acometer equinos nacionais

  19. Self: um conceito em desenvolvimento

    Directory of Open Access Journals (Sweden)

    Lídia Suzana Rocha de Macedo

    2012-08-01

    Full Text Available Diversas definições de self coexistem nas teorias e práticas psicológicas. Essa variedade é resultante de bases epistemológicas a partir das quais se adotam estratégias diferentes para abordar e demarcar os limites do objeto em questão e descrevê-lo. Este estudo teve como objetivo oferecer uma revisão dos conceitos de self e uma reflexão sobre como esse conceito se articula nas diferentes abordagens teóricas da psicologia. Destaca-se que dilemas centrais à psicologia do desenvolvimento atravessam o conceito de self. Por essa razão, apresenta-se a tese de que, ao analisar cada definição de self, deve-se buscar responder como cada teoria colocou-se diante das dicotomias estabilidade versus transformação, específico versus universal e mundo interno versus mundo externo.

  20. Mastites em ruminantes no Brasil

    Directory of Open Access Journals (Sweden)

    Atzel Candido Acosta

    Full Text Available Resumo: A mastite é uma doença complexa e considerada uma das principais causas de perdas à indústria leiteira mundial. Objetivou-se com esta revisão compilar informações dos últimos dez anos sobre a mastite em ruminantes no Brasil. A prevalência da mastite subclínica chega a 48,64% na espécie bovina, 30,7% na espécie caprina, 31,45% na espécie ovina e 42,2% na espécie bubalina, destacando-se a etiologia por Staphylococcus spp. Os fatores de risco associados à ocorrência de mastite estão relacionados a problemas no saneamento ambiental e ao manejo dos animais. As bactérias isoladas do leite mastítico apresentam maior percentual de resistência a penicilina, ampicilina, amoxicilina e neomicina e a utilização de técnicas moleculares no diagnóstico dos agentes causadores de mastites no país, ainda é escassa o que dificulta a obtenção de um diagnóstico mais rápido, sensível e específico.

    Full Text Available A crescente hegemonia do modo de produção digital de textos literários a serem disponibilizados em rede torna urgente o questionamento a respeito das possíveis mudanças que ocorrem na produção de hipertextos eletrônicos a partir de textos literários. O presente ensaio desenvolve uma reflexão crítica sobre o problema a partir de uma distinção do duplo significado de tecnologia enquanto, de um lado, instrumental para a produção de objetos e, de outro, ambiente estruturante que não só produz objetos mas, principalmente, molda os sujeitos que deles fazem uso, reconstituindo no processo hábitos e procedimentos. Se levarmos a sério o conceito de tecnologia enquanto ambiente estruturante, então é bem possível que a literatura traduzida ou produzida diretamente no formato hipertextual sofra modificações profundas quando comparadas à produção literária no meio impresso

    Maria Elisabetta Guerzoni

    2012-06-01

    Full Text Available Chemical constituents of liverwort (<em>Porella cordaeanaem> extracts have been identified using solid-phase microextraction-gas chromatography mass spectrometry (SPME-GC/MS. The methanol, ethanol and ethyl acetate extracts were rich in terpenoids such as sesquiterpene hydrocarbons (53.12%, 51.68%, 23.16%, and monoterpene hydrocarbons (22.83%, 18.90%, 23.36%, respectively. The dominant compounds in the extracts were β-phellandrene (15.54%, 13.66%, 12.10% and β-caryophyllene (10.72%, 8.29%, 7.79%, respectively. The antimicrobial activity of the extracts was evaluated against eleven food microorganisms using the microdilution and disc diffusion methods. The minimum inhibitory concentration (MIC varied from 0.50 to 2.00 mg/mL for yeast strains (<em>Saccharomyces cerevisiae 635em>, <em>Zygosacharomyces bailii 45em>, <em>Aerobasidium pullulans L6Fem>, <em>Pichia membranaefaciens OC 71em>, <em>Pichia membranaefaciens OC 70em>, <em>Pichia anomalaem> <em>CBS 5759em>, <em>Pichia anomala DBVPG 3003em> and<em> em>>Yarrowia lipolytica RO13em>, and from 1.00 to 3.00 mg/mL for bacterial strains<em> em>(Salmonella> <em>enteritidis 155em>, <em>Escherichia coli 555em> and <em>Listeria monocytogenes 56Lyem>. Methanol extract showed better activity in comparison with ethanol and ethyl acetate extracts. High percentages of monoterpene and sesquiterpene hydrocarbons could be responsible for the better antimicrobial activity.

  3. Revivendo experiências: em foco a leitura em comunidades

    Marlene Edite Pereira Rezende

    Full Text Available Este artigo teve como objetivo recuperar, de forma destacada, duas experiências de trabalho de extensão na UFMG: o carro-biblioteca da ECI\\UFMG e a implantação das Bibliotecas Públicas e Biblioteca Móvel do COLTEC\\UFMG. A estas experiências somaram-se ainda as informações sobre as atividades de extensão, através de Carros-Biblioteca, realizadas no âmbito da Biblioteca Pública Estadual Luiz de Bessa e pelo SESC. Revendo estas experiências torna-se patente a importância destas ações para as comunidades, mas, revelam-se também as dificuldades/limitações para a continuidade e ampliação destes serviços que são de caráter significativo para a população. Destaca-se também que os projetos visam permitir o acesso à leitura em comunidades com carências socioculturais, mas, demostram, de forma crítica, a realidade e os desafios dos municípios de Caparaó e Alto Caparaó na administração e manutenção das bibliotecas lá instaladas. Argumenta-se ainda, como aspecto significativo, a necessidade de articulação das comunidades, de forma a reivindicarem junto aos gestores públicos o atendimento aos direitos da população.

    Full Text Available Avaliou-se o efeito de dietas com níveis de proteína bruta ‒ PB (10, 12, 14 e 16% na matéria seca ‒ MS em vacas Holandesas mestiças com produção de leite médio (PL de 13kg/dia. Utilizou-se silagem de milho como volumoso, e a relação volumoso:concentrado foi de 75:25. Houve aumento linear para o consumo de todos os componentes da dieta, exceto para o consumo de carboidratos totais e carboidratos não fibrosos (CNF, que reduziram linearmente. O consumo dos nutrientes digestíveis totais (NDT apresentou comportamento quadrático, com valor máximo estimado de 10,13kg/dia, na dose de 15,62% de PB na dieta. As digestibilidades de PB, EE, FDN e FDNcp aumentaram linearmente. Já os valores de digestibilidade de MS, MO, CNF e NDT apresentaram efeito quadrático, estimando-se ponto de máximo de 65,09; 67,23; 78,35 e 67,92 nas doses de 15,39; 15,22; 15,62 e 15,68% de PB, respectivamente. A PL, sem e com correção para 3,5% de gordura, a variação de peso corporal e a composição do leite aumentaram linearmente, exceto para lactose, que não apresentou efeito. O nível de 14% de PB na dieta é o mais indicado para alimentação de vacas com produção média de 13kg/dia de leite.

  5. <em>Helicobacter pyloriem> Disrupts Host Cell Membranes, Initiating a Repair Response and Cell Proliferation

    Directory of Open Access Journals (Sweden)

    Hsueh-Fen Juan

    2012-08-01

    Full Text Available <em>Helicobacter pyloriem> (<em>H. pyloriem>, the human stomach pathogen, lives on the inner surface of the stomach and causes chronic gastritis, peptic ulcer, and gastric cancer. Plasma membrane repair response is a matter of life and death for human cells against physical and biological damage. We here test the hypothesis that <em>H. pyloriem> also causes plasma membrane disruption injury, and that not only a membrane repair response but also a cell proliferation response are thereby activated. Vacuolating cytotoxin A (VacA and cytotoxin-associated gene A (CagA have been considered to be major <em>H. pyloriem> virulence factors. Gastric cancer cells were infected with <em>H. pyloriem> wild type (vacA+/cagA+, single mutant (ΔvacA or ΔcagA or double mutant (ΔvacA/ΔcagA strains and plasma membrane disruption events and consequent activation of membrane repair components monitored. <em>H. pyloriem> disrupts the host cell plasma membrane, allowing localized dye and extracellular Ca2+ influx. Ca2+-triggered members of the annexin family, A1 and A4, translocate, in response to injury, to the plasma membrane, and cell surface expression of an exocytotic maker of repair, LAMP-2, increases. Additional forms of plasma membrane disruption, unrelated to <em>H.> pylori em>exposure, also promote host cell proliferation. We propose that <em>H. pyloriem> activation of a plasma membrane repair is pro-proliferative. This study might therefore provide new insight into potential mechanisms of <em>H. pyloriem>-induced gastric carcinogenesis.

  6. Net Energy, CO2 Emission and Land-Based Cost-Benefit Analyses of <em>Jatropha> em>Biodiesel: A Case Study of the Panzhihua Region of Sichuan Province in China

    Full Text Available Bioenergy is currently regarded as a renewable energy source with a high growth potential. Forest-based biodiesel, with the significant advantage of not competing with grain production on cultivated land, has been considered as a promising substitute for diesel fuel by many countries, including China. Consequently, extracting biodiesel from <em>Jatropha> curcasem> has become a growing industry. However, many key issues related to the development of this industry are still not fully resolved and the prospects for this industry are complicated. The aim of this paper is to evaluate the net energy, CO2 emission, and cost efficiency of <em>Jatropha> biodiesel as a substitute fuel in China to help resolve some of the key issues by studying data from this region of China that is well suited to growing <em>Jatropha>. Our results show that: (1 <em>Jatropha> biodiesel is preferable for global warming mitigation over diesel fuel in terms of the carbon sink during <em>Jatropha> tree growth. (2 The net energy yield of <em>Jatropha> biodiesel is much lower than that of fossil fuel, induced by the high energy consumption during <em>Jatropha> plantation establishment and the conversion from seed oil to diesel fuel step. Therefore, the energy efficiencies of the production of <em>Jatropha> and its conversion to biodiesel need to be improved. (3 Due to current low profit and high risk in the study area, farmers have little incentive to continue or increase <em>Jatropha> production. (4 It is necessary to provide more subsidies and preferential policies for <em>Jatropha> plantations if this industry is to grow. It is also necessary for local government to set realistic objectives and make rational plans to choose proper sites for <em>Jatropha> biodiesel development and the work reported here should assist that effort. Future research focused on breading high-yield varieties, development of efficient field

    Full Text Available Abstract To appreciate the influence of the introduction of the Eastern cottontail (<em>Sylvilagus floridanusem> on the food habits of the red fox (Vulpes vulpes, between June 1998 and February 2000 fox diet was investigated by means of scat analysis (N=115 in a 250 ha wide Natural Reserve of NW Italy, and compared with data collected in the same area prior to cottontail colonization (1988-1989. Comparison included also the diet of badgers (<em>Meles melesem>, considered as potential competitors for food resources. Alien lagomorphs (mean percent volume, Vm% = 68% represented by far the most exploited resource, only three other food items reaching values of mean percent volume barely higher than 5%. Cottontails frequency of occurrence did not vary according either to season or to their reproductive cycle (II-IX vs. X-I, whilst diet niche breadth varied inversely proportional to the use of this key-resource. Overall fox trophic niche breadth varied from 0.64 in 1988-89 to 0.31 in 1998-00 (B, Levin’s index. These findings led us to consider the feeding habits of the fox in the study area as a result of local specialization of a typical generalist carnivore, according to the predictions of optimal foraging theory. No variation occurred in the badger niche breadth since cottontail introduction, whilst niche overlap between foxes and badgers decreased from 0.59 to 0.13 (O, Pianka’s index, possibly reducing competition for food in summer.

    Directory of Open Access Journals (Sweden)

    Mahiran Basri

    2012-08-01

    Full Text Available <em>Pp>CHS is a member of the type III polyketide synthase family and catalyses the synthesis of the flavonoid precursor naringenin chalcone from <em>p>-coumaroyl-CoA. Recent research reports the production of pyrone derivatives using either hexanoyl-CoA or butyryl-CoA as starter molecule. The Cys-His-Asn catalytic triad found in other plant chalcone synthase predicted polypeptides is conserved in <em>Pp>CHS. Site directed mutagenesis involving these amino acids residing in the active-site cavity revealed that the cavity volume of the active-site plays a significant role in the selection of starter molecules as well as product formation. Substitutions of Cys 170 with Arg and Ser amino acids decreased the ability of the <em>Pp>CHS to utilize hexanoyl-CoA as a starter molecule, which directly effected the production of pyrone derivatives (products. These substitutions are believed to have a restricted number of elongations of the growing polypeptide chain due to the smaller cavity volume of the mutant’s active site.

    2012-05-01

    Full Text Available The knowledge of flavonoids involved in plant-plant interactions and their mechanisms of action are poor and, moreover, the structural characteristics required for these biological activities are scarcely known. The objective of this work was to study the possible <em>in vitro em>phytotoxic effects of 27 flavonoids on the germination and early radical growth of <em>Raphanus sativus em>L.> and <em>Lepidium sativumem> L., with the aim to evaluate the possible structure/activity relationship. Moreover, the antioxidant activity of the same compounds was also evaluated. Generally, in response to various tested flavonoids, germination was only slightly affected, whereas significant differences were observed in the activity of the various tested flavonoids against radical elongation. DPPH test confirms the antioxidant activity of luteolin, quercetin, catechol, morin, and catechin. The biological activity recorded is discussed in relation to the structure of compounds and their capability to interact with cell structures and physiology. No correlation was found between phytotoxic and antioxidant activities.

    Postmenopausal osteoporosis is a highly prevalent disease. Prevention through lifestyle measures includes an adequate calcium intake. Despite the guidance provided by scientific societies and governmental bodies worldwide, many issues remain unresolved. To provide evidence regarding the impact of calcium intake on the prevention of postmenopausal osteoporosis and critically appraise current guidelines. Literature review and consensus of expert opinion. The recommended daily intake of calcium varies between 700 and 1200mg of elemental calcium, depending on the endorsing source. Although calcium can be derived either from the diet or supplements, the former source is preferred. Intake below the recommended amount may increase fragility fracture risk; however, there is no consistent evidence that calcium supplementation at, or above, recommended levels reduces risk. The addition of vitamin D may minimally reduce fractures, mainly among institutionalised people. Excessive intake of calcium, defined as higher than 2000mg/day, can be potentially harmful. Some studies demonstrated harm even at lower dosages. An increased risk for cardiovascular events, urolithiasis and even fractures has been found in association with excessive calcium intake, but this issue remains unresolved. In conclusion, an adequate intake of calcium is recommended for general bone health. Excessive calcium intake seems of no benefit, and could possibly be harmful. Copyright © 2017 Elsevier B.V.

    Women form a large part of many workforces throughout Europe. Many will be working throughout their menopausal years. Whilst the menopause may cause no significant problems for some, for others it is known to present considerable difficulties in both their personal and working lives. During the menopausal transition women report that fatigue and difficulties with memory and concentration can have a negative impact on their working lives. Furthermore, hot flushes can be a source of embarrassment and distress. Some consider that these symptoms can impact on their performance. Greater awareness among employers, together with sensitive and flexible management can be helpful for women at this time. Particular strategies might include: fostering a culture whereby employees feel comfortable disclosing health problems, allowing flexible working, reducing sources of work-related stress, providing easy access to cold drinking water and toilets, and reviewing workplace temperature and ventilation.

    In this paper the instrumentation of a 500 kJ, 15 mm bore diameter railgun and the power switching are described in detail. Emphasis has been laid on electro-optical measurement techniques. The presented results include electrical measurements on the switching circuit, breech and muzzle voltages and projectile position. In addition, material problems concerning rail erosion with plasma-driven projectiles are discussed. After some ten shots with peak currents up to 600 kA, rails and insulators were fully operational. The rail material loss has been tolerable. The surface roughness increased remarkably, due to the formation of a porous heterogeneous, nearly insulating surface layer of variable thickness

    Full Text Available Abstract Little is known on the ecology and behaviour of alpine mountain hare (<em>Lepus timidusem>. Between 1996 and 1997 we analysed by radiotracking the pattern of space use of 8 mountain hares from the Swiss Alps. We estimated home range size using both the kernel density estimator and the minimum convex polygon. We found smaller ranges (38 ha compared to those reported for the species in boreal or arctic habitats, but similar to ranges in Scotland. Hares did not use a centre of major activity (core area and showed high home range overlap, confirming their non-territorial behaviour. Smaller ranges were used during winter compared to the other seasons, whilst no difference in size was found between sexes. Riassunto Dinamica dell'uso dello spazio della lepre bianca (<em>Lepus timidusem> nelle Alpi Svizzere Le informazioni relative all'ecologia e al comportamento della lepre alpina (<em>Lepus timidusem> sono ad oggi scarse.

    The Office of Technology Development (TD) supports research and development of technologies that will lower cost, reduce risk, improve safety, and accelerate cleanup of the Nuclear Weapons Complex and provide solutions to currently untractable environmental problems. The TD strategic plan outlines Applied Research, Development, Demonstration, Testing, and Evaluation (RDDT and E) that will provide needed technology products to be used by Environmental Restoration and Waste Management operations (i.e., our customers). The TD strategic plan is derived from EM Goals, Objectives, and Strategy and is incorporated into DOE'S Five-Year Plan for Environmental Restoration and Waste Management. The TD strategic plan is developed based on integrating customer requirements, and is complemented by a top-down, bottom-up analysis of Site Specific Technology Needs and environmental problems. The execution of TD's strategic plan is implemented largely through Integrated Programs (IP) and Integrated Demonstrations (ID). IDs have proven to be a cost-effective method of managing technology development, testing and evaluation, and implementation of successful technology systems into the DOE Environmental Restoration and Waste Management Programs. The Savannah River ID for Volatile Organic Compounds (VOCs) in Saturated Soils resulted in a 51 percent cost savings over stand-alone demonstrations, saving over $8 million. The IPs and IDs are selected based on customer needs, technical complexity, and complex-wide regulatory and compliance agreements. New technology systems are selected for incorporation into an IP or ID from offerings of the DOE laboratories, industry, and the universities. A major TD initiative was announced in August 1991, with the release of a Program Research and Development Announcement (PRDA) requesting industry and universities to propose innovative new technologies to clean up the Weapons Complex.

    As a reflection of its growing culture of openness, and in response to the public's need for accurate information about its activities, the U.S. Department of Energy (DOE) Office of the Assistant Secretary for Environmental Restoration and Waste Management (EM) has increased the amount of information available to the public through communication tools such as brochures, fact sheets, and a travelling exhibit with an interactive computer display. Our involvement with this effort has been to design, develop, and critique booklets, brochures, fact sheets and other communication tools for EM. This paper presents an evaluation of the effectiveness of two communication tools we developed: the EM Booklet and the EM Fact Sheets. We measured effectiveness using non-parametric testing. This paper describes DOE's culture change, EM's communication tools and their context within DOE'S new open culture, our research, test methods and results, the significance of our research, and our plans for future research.

    Full Text Available <em>Vulpes vulpesem> (Linnaeus, 1758 is one of the most common carnivore in Italy and its spread includes almost the whole national territory. The species shows an high ecological plasticity and a variable diet composition connected in part to human sources. This high adaptability permits the red foxes to colonize different habitats like the suburbs of large cities as well as the small villages located in mountain areas. On the other hand, the tourism pressure seems to assume a great importance in the Alps, also in those areas where the foxes live. So, indirect interactions could take place between these animals and the humans. The role of <em>V. vulpesem> in the zoonoses has not to be understated since this carnivore could transmit parasitic diseases that are able to cause serious pathologies in humans. This study aims just to investigate on intestinal communities of helmiths of <em>V. vulpesem> in order to make progress in current knowledge on epidemiological situation in Italian Alps. During 1998-2003, we have examined 450 foxes from Trentino Alto Adige, Veneto, Lombardia and Valle d'Aosta. The specimens collected were found dead or have been hunted (according to national law n. 157/92 in localities situated between 170 and 2200 m a.s.l. The carcasses were carried to the provincial sections of Zooprofilattici Institutes, where the intestine was drawn by each sample and all the material was sent to the Faculty of Veterinary Medicine of Milan. Parasitological examination of the small intestines was performed by the analysis of the whole sediment and counting technique (SCT. Parasites were preserved in alcohol 70° before to be clarified or stained and identified by microscope (Zeiss Axioscop.

    Odílio Alves Aguiar

    2015-07-01

    Full Text Available O presente artigo visa refletir sobre o pensamento de Hannah Arendt à luz do par conceitual necessidade-liberdade. Esse caminho é produtivo, pois dá conta tanto da obra mais conhecida e reconhecida da autora quanto das suas reflexões anteriores à Origens do Totalitarismo, que se dirigiam, na sua maioria, à comunidade dos Judeus e tinham a questão judaica como ponto central. As meditações arendtianas sobre o judaísmo, consideradas no presente artigo, foram publicadas em duas coletâneas na França: La tradition Cachée (1987 e Auschwitz et Jérusalem (1991. O artigo gravita em torno da defesa arendtiana sobre a inerência entre política e liberdade e sua substituição pela compreensão da política como submetida à esfera da necessidade. Essa perspectiva, segundo a autora, fez-se presente na tradição assimilacionista entre os judeus, mas já tinha obtido a hegemonia na cultura ocidental. Isso sucedeu em razão da primazia da vita contemplativa sobre a vita activa, do trabalho e da questão social em detrimento da ação e, por fim, da supremacia da filosofia da história em prejuízo da Filosofia Política.

    Full Text Available CONTEXT: Several studies have demonstrated a higher prevalence of celiac disease (CD among females with Turner syndrome when compared to the general population. Nevertheless, there is no record in literature concerning this investigation among Brazilian patients. OBJECTIVE: To assess the prevalence of CD among a group of Brazilian patients with Turner syndrome. METHODS: Fifty-six females with Turner syndrome and on gluten-containing diet were screened for CD utilizing immunoglobulin A antiendomysium (IgA-EMA and immunoglobulin A anti-tissue transglutaminase (IgA-tTG antibody assays. Additionally, they were genotyped for CD human leukocyte antigen (CD-HLA predisposing alleles. Patients showing positivity in serological testing were offered to perform small intestine biopsy for histological confirmation. RESULTS: Mean age at diagnosis of Turner syndrome was 5.5 ± 4.4 years; mean age at screening for CD was 17.0 ± 9.3 years (from 10 months of age to 52 years. Two girls were positive for IgA-EMA and IgA-tTG, presented predisposing HLA-DQ2 alleles and both had the diagnosis of CD confirmed by jejunal biopsy. CONCLUSION: The 3.6% prevalence of biopsy-proven CD among this group of females with Turner syndrome is 10 times higher than the one among females from the general population of the same geographical area. This result provides additional support to an association between these two disorders and restates that girls and women with Turner syndrome represent a high risk population for developing CD.CONTEXTO: Alguns estudos têm demonstrado maior prevalência de doença celíaca entre mulheres com síndrome de Turner, quando comparadas com a população geral. Entretanto, não há registro na literatura desta investigação em pacientes brasileiras.

    Full Text Available O cavalo, dado o seu meio ambiente, está sujeito a afecções frequentes da córnea e da conjuntiva, tecidos oculares bastante expostos a bactérias e fungos, principalmente Aspergillus spp. e Fusarium spp. As ceratites ulcerativas bacterianas e fúngicas, bem como as ceratites fúngicas não ulcerativas, caracterizadas principalmente pelo abscesso estromal, são frequentes nessa espécie. Ocorrida a lesão inicial, perpetua-se um ciclo vicioso, com liberação de citocinas inflamatórias, que desencadeiam uma rápida e severa infiltração corneal por células polimorfonucleares. A córnea torna-se sujeita à destruição por enzimas proteolíticas liberadas pelos micro-organismos e por células inflamatórias, capazes de desencadear a dissolução estromal e a perfuração do bulbo ocular. O tratamento clínico para a resolução da doença corneal e o controle da uveíte reflexa deve ser agressivo e associado, muitas das vezes, à terapia cirúrgica. Este artigo discorre sobre a fisiopatologia e o tratamento da ceratomicose em equinos.Environmental and behavioral factors make horses susceptible to corneal and conjunctival lesions, since these structures are constantly exposed to bacteria and fungi specially Aspergillus spp. and Fusarium spp. Bacterial and fungal ulcerative keratitis, as well as non-ulcerative fungal keratitis such as stromal abscess, are frequent in horses. A "cascade" effect follows the initial lesion which triggers the release of inflammatory cytokines followed by an acute and severe infiltrate of polymorphonuclear cells in the cornea. The cornea becomes susceptible to the activity of proteolytic enzymes released by microorganisms and polymorphonuclear cells, resulting in stromal degradation and ocular perforation. The medical treatment targeting the corneal disease and the controlling of reflexive uveitis should be aggressive and surgical therapy should be associated in most of the cases.

    Highlights: • Breaking up of an intense EM pulse into filaments is a spectacular demonstration of the nonlinear wave-plasma interaction. • Filaments are spectacularly sharper, highly extended and longer lived at relativistic temperatures. • EM energy concentration can trigger new nonlinear phenomena with absolute consequences for high energy density matter. - Abstract: Through 2D particle-in-cell (PIC) simulations, we demonstrate that the nature of filamentation of a high intensity electromagnetic (EM) pulse propagating in an underdense plasma, is profoundly affected at relativistically high temperatures. The “relativistic” filaments are sharper, are dramatically extended (along the direction of propagation), and live much longer than their lower temperature counterparts. The thermally boosted electron inertia is invoked to understand this very interesting and powerful phenomenon.

    1994-01-01

    The mission of EM-60 is to plan, implement, and manage receipt of surplus facilities resulting from downsizing of the DOE Weapons Complex facilities and DOE operating program offices to EM, and to ensure prompt deactivation of such facilities in order to reach a minimum surveillance and maintenance condition. The revised organizational structure of EM-60 into four offices (one at headquarters, and the other three at field sites), reflects increased operating functions associated with deactivation, surveillance, and maintenance of facilities. EM-60's deactivation and transition role concerns technical, socioeconomic, institutional, and administrative issues. The primary objective of the deactivation process is to put facilities in the lowest surveillance and maintenance condition safely and quickly by driving down the open-quotes mortgageclose quotes costs of maintaining them until final disposition. EM-60's three key activities are: (1) Inventory of surplus facilities - The 1993 Surplus Facility Inventory and Assessment (SFIA) serves as a planning tool to help the Department and EM-60 determine optimal transition phasing, with safety and cost-effectiveness remaining a priority. (2) Management of accelerated facility life cycle transition - Transitions currently underway illustrate site issues. These include addressing the interests of federal and state regulatory agencies as well as interests of local stakeholders, safe management of large amounts of production residues, and options for treatment, storage, transportation, and disposal. Of equal importance in the transition process is planning the optimal transition of the labor force. (3) Economic development - to address the socio-economic impacts on affected communities of the severe and rapid downsizing of the DOE Weapons Complex, DOE is pursuing an approach that uses the land, equipment, technology assets, and highly skilled local workforces as a basis for alternative economic development

    Full Text Available Through bioassay-guided fractionation of the extracts from the aerial parts of the Chinese herb <em>Hypericum japonicumem> Thunb. Murray, Isojacareubin (ISJ was characterized as a potent antibacterial compound against the clinical methicillin-resistant S<em>taphylococcus aureusem> (MRSA. The broth microdilution assay was used to determine the minimal inhibitory concentrations (MICs and minimal bactericidal concentrations (MBCs of ISJ alone. The results showed that its MICs/MBCs ranged from 4/16 to 16/64 μg/mL, with the concentrations required to inhibit or kill 50% of the strains (MIC50/MBC50 at 8/16 μg/mL. Synergistic evaluations of this compound with four conventional antibacterial agents representing different types were performed by the chequerboard and time-kill tests. The chequerboard method showed significant synergy effects when ISJ was combined with Ceftazidime (CAZ, Levofloxacin (LEV and Ampicillin (AMP, with the values of 50% of the fractional inhibitory concentration indices (FICI50 at 0.25, 0.37 and 0.37, respectively. Combined bactericidal activities were also observed in the time-kill dynamic assay. The results showed the ability of ISJ to reduce MRSA viable counts by log10CFU/mL at 24 h of incubation at a concentration of 1 × MIC were 1.5 (LEV, additivity, 0.92 (CAZ, indifference and 0.82 (AMP, indifference, respectively. These <em>in vitroem> anti-MRSA activities of ISJ alone and its synergy with conventional antibacterial agents demonstrated that ISJ enhanced their efficacy, which is of potential use for single and combinatory therapy of patients infected with MRSA.

    Este trabalho teve por objetivo avaliar o teor de amido resistente (AR em farinhas de banana verde produzidas a partir de treze genótipos de bananeira. Para a produção da farinha foram separadas a 1ª, 3ª e 5ª pencas de cada genótipo, na qual cada penca correspondeu a uma repetição. Os frutos de cada penca no estádio 1 (casca completamente verde de maturação foram descascados manualmente, cortados em fatias circulares de 0,5 cm e desidratados em estufa com circulação de ar a 40ºC por 48 horas, sendo em seguida moídos. A análise de AR consistiu em um processo enzimático, calculando-se o conteúdo final pela concentração de glicose liberada. Os resultados foram submetidos à análise estatística e mostraram diferenças significativas para o teor de AR nas farinhas obtidas dos genótipos de bananeira, sendo que a farinha com maior teor de AR foi a produzida a partir do cultivar ‘Nam’ (40,25% e a menor pelo híbrido ‘Fhia 01’ (10,01%. Pode-se concluir que o conteúdo de AR varia em relação ao genótipo utilizado para a confecção da farinha e que a banana pode ser uma boa opção de estudo de alimento funcional.

We examined roost selection in a breeding population of <em>B. barbastellusem> from the Abruzzo Lazio and Molise National Park (central Italy at three levels: woodland structure and management type; tree characteristics; and cavity characteristics. In 2001-2002, we fitted 31 adult <em>B. barbastellusem> (29 lactating females, one pregnant female and one male with 0.48g radio-tags and tracked them to their roost-trees. The bats were tracked for 4.5 ± 3.7 days (range: 0-12 days. We located 33 roosts used by 25 subjects (1.8±1.2 roosts/bat, range 1-5. The bats switched roosts frequently: 13 bats used more than one tree over the study period. A chi-square analysis showed that the roosts were not distributed at random across woodland categories: unmanaged woodland was positively selected, whereas shelterwood-harvested woodland was used in proportion to its availability, and ?pastures+scattered trees? was avoided. Twenty out of 33 roost trees were dead <em>Fagus sylvaticaem> trees; conversely, living <em>F. sylvaticaem> dominated in a tree sample obtained at random; dead trees were used more than expected (Χ² test, <em>P> <0.001.

    Full Text Available Introdução: A escabiose consiste em uma doença contagiosa causada pelo ácaro Sarcoptes scabie, parasita exclusivo da pele humana, transmitida pelo contato direto com pessoa infectada. Pode ocorrer em qualquer faixa etária, independente do sexo, etnia ou hábitos de higiene, sendo diagnosticada com base na história de coceira noturna, associada a lesões cutâneas. Em geral, há mais de um caso na mesma residência. Apresenta diversos diagnósticos diferenciais por ser essencialmente uma dermatite. Objetivo: Alertar para possibilidade de escabiose na comunidade. Metodologia: As informações contidas nesse relato foram obtidas por meio de consultas médicas, registros fotográficos, evolução, hipóteses diagnósticas e revisão de literatura. Relato de Caso: E.T.L.T, sexo feminino. Aos 21 dias de vida, mãe relata vermelhidão nas costas da paciente e ao exame físico observa-se eritema máculo papular na região de transição parieto-occipital do crânio. A conduta baseia-se em orientação quanto à lavagem de roupa de cama com sabão de coco, remoção de xampu e talco e observação do rash cutâneo. Treze dias depois, mãe refere piora das manchas vermelhas e aparecimento de lesões em tórax anterior e posterior, pescoço e face. Relata ainda, ter cachorro em casa e lesões semelhantes em seu próprio tórax e mamas antes mesmo de a criança nascer. A orientação foi mantida, além de ser receitado enxofre precipitado a 10% para a mãe e a 5% para a criança. Após cinco dias de tratamento, as manchas regrediram e a paciente voltou a ser amamentada. Conclusão: A escabiose continua a ser uma dermatose frequente, cujo tratamento em idade pediátrica se restringe aos “steps” para o diagnóstico correto, desinfecção dos fômites e uso de um bom escabicida, tanto para a criança quanto para seus cuidadores.

    In a very famous passage of his <em>Institutes>, the ancient jurist Gaius had divided the Roman Private Law in two parts: the Civil Law and the Law of People. The former is the Law created by the Roman people, whereas the latter is the Law followed by every nation.

    Despite its classical origin, there is some disagreement among specialists about the right way to interpret this distinction. By the beginning of the 20th century, historians like Michel Villey had seen in this distinction the influence of Greek philosophy (Stoic but even Aristotelian among the Roman jurists. But Levy and more recently Kelly have challenged this view and proposed that, in the roman period, philosophers and jurists had completely distinct notions of nature and natural law. The aim of this paper is not to prove the exact influence of Greek philosophy among jurists, but only to suggest that it is not possible to give an interpretation of the classical texts without ascribing to them a theoretical notion of the natural law.

    Em uma famosa passagem de suas <em>Institutas>, o jurista romano Gaio dividiu o direito privado em duas partes: o direito civil e o direito dos povos. O primeiro é o direito criado pelo povo romano enquanto o segundo é o direito seguido por todas as nações. A despeito de sua origem clássica, os especialistas discordam acerca do modo de interpretar essa tese. No início do século XX, historiadores como Michel Villey viram na distinção sinais da influência da filosofia grega (estóica e mesmo aristotélica entre os juristas romanos. Posteriormente Levy e mais recentemente Kelly contestaram essa afirmação e defenderam que filósofos e juristas possuíam, no período clássico, noções de natureza e direito natural completamente distintas. O objetivo desse artigo não está em provar a exata influência da filosofia grega entre os juristas, mas apenas em sugerir que não é possível fornecer uma interpretação dos

    Full Text Available Este trabalho analisa a realidade do ensino de língua espanhola em escolas de Ensino Fundamental e Médio da cidade de Pelotas (RS. A ideia surgiu a partir de observações realizadas na disciplina de Estágio de Observação, do curso de Português e Espanhol da UFPel, no semestre 2015/1, a partir do momento em que se pôde perceber que o que o estagiário encontra em sala de aula não condiz com o que é estudado, principalmente em aulas de Linguística Aplicada. Para este estudo, utilizaram-se relatos obtidos pelo autor deste trabalho e de mais quatro informantes, os quais estagiaram em escolas da rede pública pelotense no mesmo período. A análise comparativa fundamentou-se principalmente em textos de teorias de aprendizagem de línguas estrangeiras e nos PCN’s para o ensino de LE’s no Brasil, de modo a contrastar o que afirmam os teóricos e o que realmente encontrou-se nas escolas. Este estudo ancora-se na abordagem qualitativa e na metodologia aplicada por serem formas de pesquisa mais relacionadas às experiências humanas, suas interpretações terem carácter mais flexível e por permitirem uma melhor aplicação ao ensino e aprendizagem de LE. Os resultados obtidos indicam que a realidade do ensino de espanhol nas escolas difere do que ensinam os professores na universidade, pois se percebeu que o ensino dessa língua é precário, não indo ao encontro do que sugerem os PCN’s, no que se refere à transformação do aluno em agente discursivo em LE.Palavras-chave: aprendizagem, espanhol, língua estrangeira.

    Full Text Available La martora, <em>Martes martesem>, è un mustelide storicamente presente su gran parte del territorio italiano, soprattutto dove siano presenti foreste mature altamente strutturate e ricche di risorse. Nel corso dei decenni passati, cause quali la deforestazione con conseguente frammentazione dell'habitat, la caccia e la persecuzione da parte dell'uomo hanno portato ad un sensibile declino sia nel numero d'individui sia di popolazioni in tutta l'Europa. Frammentazione degli areali e diminuzione del numero di soggetti costituiscono le cause principali di un limitato flusso genico con conseguente formazione di popolazioni isolate di martora e perdita di variabilità genetica (Kyle <em>et al.em>, 2003. Per queste ragioni la martora risulta attualmente tutelata secondo quanto previsto dalla Convenzione di Berna (appendice III e dalla Direttiva europea 92/43/CEE "Habitats & Species". Di fronte a prospettive di tipo conservazionistico, diventa necessario disporre di metodologie per la valutazione della variabilità residua nella specie a livello d'individui e di popolazioni. Secondo numerosi Autori, i microsatelliti costituiscono marcatori molto efficaci nella descrizione della struttura genetica e della storia demografica di specie (Beaumont & Bruford, 1999; Linares, 1999. Il presente lavoro propone i risultati ottenuti attraverso il confronto di due campioni costituiti da individui di <em>Martes martesem> provenienti dalla Sardegna (25 esemplari e dal territorio italiano (6 esemplari.

    Full Text Available The complete 15,413-bp mitochondrial genome (mitogenome of <em>Sesamia inferensem> (Walker (Lepidoptera: Noctuidae was sequenced and compared with those of four other noctuid moths. All of the mitogenomes analyzed displayed similar characteristics with respect to gene content, genome organization, nucleotide comparison, and codon usages. Twelve-one protein-coding genes (PCGs utilized the standard ATN, but the <em>cox1 em>gene used CGA as the initiation codon; <em>cox1em>, <em>cox2em>, and <em>nad4em> genes had the truncated termination codon T in the <em>S. inferens em>mitogenome. All of the tRNA genes had typical cloverleaf secondary structures except for <em>trnS1(AGNem>, in which the dihydrouridine (DHU arm did not form a stable stem-loop structure. Both the secondary structures of <em>rrnL> and <em>rrnS> genes inferred from the <em>S. inferens em>mitogenome closely resembled those of other noctuid moths. In the A+T-rich region, the conserved motif “ATAGA” followed by a long T-stretch was observed in all noctuid moths, but other specific tandem-repeat elements were more variable.

Assim, o ódio é representado nos primeiros círculos de socialização (na família e na escola, mais tarde surge também em esferas sociais mais complexas. Em todos esses espaços, os personagens se utilizam de discursos diversos para legitimá-lo, evidenciando a labilidade da cultura como barreira discursiva do princípio da violência. Apesar da maleabilidade da cultura no processo de configuração dessa emoção e sua livre exposição, os protagonistas acabam confrontados com um excesso emocional não compreendido, levando um à afasia e outro à destruição da família, com o objetivo de calar o indesejado.

    2018-01-01

    In many electromagnetic (EM) methods - such as magnetotelluric, spectral-induced polarization (SIP), time-domain-induced polarization (TDIP), and controlled-source audio magnetotelluric (CSAMT) methods - it is important to evaluate and test the EM receivers during their development stage. To assess the performance of the developed EM receivers, controlled synthetic data that simulate the observed signals in different modes are required. In CSAMT and SIP mode testing, the waveform generator should use the GPS time as the reference for repeating schedule. Based on our testing, the frequency range, frequency precision, and time synchronization of the currently available function waveform generators on the market are deficient. This paper presents a multifunction waveform generator with three waveforms: (1) a wideband, low-noise electromagnetic field signal to be used for magnetotelluric, audio-magnetotelluric, and long-period magnetotelluric studies; (2) a repeating frequency sweep square waveform for CSAMT and SIP studies; and (3) a positive-zero-negative-zero signal that contains primary and secondary fields for TDIP studies. In this paper, we provide the principles of the above three waveforms along with a hardware design for the generator. Furthermore, testing of the EM receiver was conducted with the waveform generator, and the results of the experiment were compared with those calculated from the simulation and theory in the frequency band of interest.

    Full Text Available Eucalyptus bark contains significant amounts of triterpenoids with demonstrated bioactivity, namely triterpenic acids and their acetyl derivatives (ursolic, betulinic, oleanolic, betulonic, 3-acetylursolic, and 3-acetyloleanolic acids. In this work, the supercritical fluid extraction (SFE of <em>Eucalyptus> <em>globulus> deciduous bark was carried out with pure and modified carbon dioxide to recover this fraction, and the results were compared with those obtained by Soxhlet extraction with dichloromethane. The effects of pressure (100–200 bar, co-solvent (ethanol content (0, 5 and 8% wt, and multistep operation were studied in order to evaluate the applicability of SFE for their selective and efficient production. The individual extraction curves of the main families of compounds were measured, and the extracts analyzed by GC-MS. Results pointed out the influence of pressure and the important role played by the co-solvent. Ethanol can be used with advantage, since its effect is more important than increasing pressure by several tens of bar. At 160 bar and 40 °C, the introduction of 8% (wt of ethanol greatly improves the yield of triterpenoids more than threefold.

    2012-08-01

    Full Text Available High permittivity (<em>k> gate dielectric films are widely studied to substitute SiO2 as gate oxides to suppress the unacceptable gate leakage current when the traditional SiO2 gate oxide becomes ultrathin. For high-<em>k> gate oxides, several material properties are dominantly important. The first one, undoubtedly, is permittivity. It has been well studied by many groups in terms of how to obtain a higher permittivity for popular high-<em>k> oxides, like HfO2 and La2O3. The second one is crystallization behavior. Although it’s still under the debate whether an amorphous film is definitely better than ploy-crystallized oxide film as a gate oxide upon considering the crystal boundaries induced leakage current, the crystallization behavior should be well understood for a high-<em>k> gate oxide because it could also, to some degree, determine the permittivity of the high-<em>k> oxide. Finally, some high-<em>k> gate oxides, especially rare earth oxides (like La2O3, are not stable in air and very hygroscopic, forming hydroxide. This topic has been well investigated in over the years and significant progresses have been achieved. In this paper, I will intensively review the most recent progresses of the experimental and theoretical studies for preparing higher-<em>k> and more stable, in terms of hygroscopic tolerance and crystallization behavior, Hf- and La-based ternary high-<em>k> gate oxides.

Esta pesquisa teve autorização do Sistema de Autorização e Informação em Biodiversidade do Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis para ser realizado. Utilizaram-se 19 serpentes da família Boidae mantidas em cativeiro, pertencentes ao "Museu Paraense Emilio Goeldi" (Belém/PA e "Sítio Xerimbabo" (Santo Antônio do Tauá/PA. A pesquisa de hemogregarina foi realizada em esfregaços sanguíneos examinados no aumento de 400x, enquanto que a parasitemia foi determinada contando- se 550 hemácias em aumento de 1000x. Do total de animais estudados (n=19, nove encontraram-se parasitados (47,36%, não havendo correlação entre presença de hemogregarina, pré-disposição sexual, alterações clínicas e hematológicas nas serpentes hospedeiras. A correlação da hemoparasitose foi detectada apenas quanto à presença de ectoparasitas nas serpentes, no entanto, estudos adicionais são necessários para verificar a prevalência de hemogregarinas em animais mantidos em cativeiro no Estado do Pará, visto que, existe grande lacuna de dados na literatura veterinária especializada no que diz respeito à fauna da região amazônica.

    Full Text Available Num estudo retrospectivo de 1.071 necropsias de bovinos, foram encontrados 20 casos de babesiose cerebral confirmados pelo exame de esfregaços do córtex telencefálico. A maioria desses casos ocorreu no verão, em bovinos adultos de raças européias ou suas cruzas. Além dos sinais clínicos neurológicos, observou-se hemoglobinúria, anorexia, febre, taquicardia, taquipnéia e queda na produção de leite. O hemograma realizado em cinco bovinos afetados revelou acentuada anemia regenerativa; em média, 20% dos eritrócitos estavam parasitados por Babesia bovis. Na necropsia de todos os casos, a substância cinzenta dos córtices telencefálico e cerebelar e dos núcleos da base era consistente e caracteristicamente róseo-cereja. Essa coloração devia-se ao seqüestro de eritrócitos nos capilares encefálicos. Nesses eritrócitos, podiam-se observar, tanto em esfregaços do córtex como em preparações histológicas do encéfalo, microorganismos com morfologia compatível com B. bovis. Outros achados de necropsia incluíam hemoglobinúria, rins vermelho-escuros, hepatoesplenomegalia, fígado vermelho-alaranjado, icterícia, hemorragias epicárdicas e endocárdicas e edema e congestão dos linfonodos mesentéricos.

  14. Regional EM studies in the 80's

    1987-09-01

    The review describes in broad terms the development of regional EM studies during the last five-six years. Large simultaneous magnetometer arrays, broadband and dense profiling with five component instruments, the use of remote reference techniques and in-field data processing have increased both the number and the quality of EM surveys. The increase has been strong all over the world. An extensive list of references, divided geographically, is presented. Selected examples of regional resisitivity-versus-depth curves are shown for Africa, the Baikal region, the Baltic Shield, the Canadian Shield, the Carpathian regions, the Central Andes, Iceland, India, the Juan de Fuca Plate, the Münsterland Basin, the Rio Grande rift, the Scottish Caledonides, the Tasman Sea, and for the United States in general. Because of the influence of tectonic settings and the metamorphic grade of rocks, only qualitative aspects of the results are relevant. ‘Classical’ array studies, especially in Australia, in the Carpathian regions, in India, in North Germany and in Scotland have been reinterpreted and completed with more accurate 2D modelling and dense MT profiling. In the USA and Canada also new regions have been surveyed extensively. New regional EM work has been conducted extensively on the Baltic Shield and in Central and North Africa, Siberia, China, in the areas around the Caspian and Black Seas and in South America. The newest studies are supported by or compared with other geophysical data, which also are used in extrapolating for missing EM data density. There are several successful large-scale projects in operation: the European Geotraverse (EGT), the KAPG International Geotraverses and the EMSLAB project (with its first preliminary results). Regional EM studies have been increasingly applied to geothermal, hydrocarbon and mineral prospecting as well as local structural studies, e.g. studies of sites for nuclear waste disposal.

    Full Text Available A series of twenty-five novel salicylanilide <em>N>-alkylcarbamates were investigated as potential acetylcholinesterase inhibitors. The compounds were tested for their ability to inhibit acetylcholinesterase (AChE from electric eel (<em>Electrophorus electricusem> L.. Experimental lipophilicity was determined, and the structure-activity relationships are discussed. The mode of binding in the active site of AChE was investigated by molecular docking. All the discussed compounds expressed significantly higher AChE inhibitory activity than rivastigmine and slightly lower than galanthamine. Disubstitution by chlorine in C'(3,4 of the aniline ring and the optimal length of hexyl-undecyl alkyl chains in the carbamate moiety provided the most active AChE inhibitors. Monochlorination in C'(4 exhibited slightly more effective AChE inhibitors than in C'(3. Generally it can be stated that compounds with higher lipophilicity showed higher inhibition, and the activity of the compounds is strongly dependent on the length of the <em>N>-alkyl chain.

    “Locas al Rescate: The Transnational Hauntings of Queer <em>Cubanidad>” (originally published in <em>Cuba Transnationalem> offers a significant contribution both to transnational American Studies and to gender studies. In telling the insider story of the alternative identity formation, practices, and forms of “rescue” initiated by the affective activism of the Cuban American society in drag in 1990s Miami/South Beach, Lima resuscitates the liberatory gestures of a subculture defined by its pursuit of its own acceptance, value, and freedom. With their aesthetic and political life on a raft, the gay micro-communities inside Cuban America asserted their own islandic space, Lima observes, performing “takeovers” in and of parks and bars and beaches—creating a post-Habermasian sphere of public activism focused on private parts, saving themselves from AIDS, from the disaffection and disaffiliation of the right-wing Cuban immigrant community, and from the failure of their own yearning to belong, to be wanted, to be embodied as the figure of their compelling <em>Cubanidad>. Against the hegemony of the invented collective politics of the sacrificing immigrants whose recognition of the queer side of being (of a being constituted by identity loss is yet to come, Lima suggests a spectral return—a personal and transnational reckoning of those whose lives the dream of freedom drowned.

    Full Text Available O artigo analisa as associações negras pelotenses que permitiram a constituição de uma identidade negra positiva percebida em relação direta com o contexto relacional vivenciado em âmbito nacional e internacional. Destacamos ainda a busca por um entrelaçamento entre diferentes associações tendo como ponto em comum a identificação racial mediada pela busca por uma posição social diferenciada. Diretamente vinculado ao período do pós-Abolição almejava-se a cidadania em uma sociedade ainda muito preconceituosa racialmente. A delimitação espacial focaliza o estudo na cidade de Pelotas, localizada no extremo sul do Rio Grande do Sul, entre os anos de 1820 a 1943. Tem inicio com a criação da primeira irmandade negra em 1820. Dentre as associações destacamos o surgimento dos clubes sociais negros (1917-1931 e suas atividades em conjunto, com ênfase para o surgimento da Frente Negra Pelotense (1933 e a busca por uma identidade racial que fosse comungada por todo o grupo negro local.

    The Electron Microscopy DataBank (EMDB) is growing rapidly, accumulating biological structural data obtained mainly by electron microscopy and tomography, which are emerging techniques for determining large biomolecular complex and subcellular structures. Together with the Protein Data Bank (PDB), EMDB is becoming a fundamental resource of the tertiary structures of biological macromolecules. To take full advantage of this indispensable resource, the ability to search the database by structural similarity is essential. However, unlike high-resolution structures stored in PDB, methods for comparing low-resolution electron microscopy (EM) density maps in EMDB are not well established. We developed a computational method for efficiently searching low-resolution EM maps. The method uses a compact fingerprint representation of EM maps based on the 3D Zernike descriptor, which is derived from a mathematical series expansion for EM maps that are considered as 3D functions. The method is implemented in a web server named EM-SURFER, which allows users to search against the entire EMDB in real-time. EM-SURFER compares the global shapes of EM maps. Examples of search results from different types of query structures are discussed. We developed EM-SURFER, which retrieves structurally relevant matches for query EM maps from EMDB within seconds. The unique capability of EM-SURFER to detect 3D shape similarity of low-resolution EM maps should prove invaluable in structural biology.

    Full Text Available OBJETIVO: Identificar vantagens e desvantagens do uso de segmentos em relação ao sorteio feito a partir da lista completa de endereços, para o sorteio de domicílios em amostragem por conglomerados em múltiplos estágios em favelas. PROCEDIMENTOS METODOLÓGICOS: Estudo qualitativo realizado em quatro favelas sorteadas no Inquérito de Saúde do Município de São Paulo, SP, 2008, nas quais foram aplicadas as duas técnicas. Foram realizados grupos focais com pesquisadores de campo - "arroladores" e entrevistadores do inquérito. Os conteúdos das conversações foram analisados, agrupados em categorias e organizados em núcleos temáticos. ANÁLISE DOS RESULTADOS: A utilização de segmentos de domicílios foi associada a numerosas vantagens e poucas desvantagens. Entre as vantagens, constaram a rapidez e facilidade na elaboração do cadastro de endereços e na localização e identificação de domicílios na etapa de realização das entrevistas, maior segurança dos entrevistadores e da população, maior acesso aos entrevistados, maior estabilidade e maior cobertura do cadastro produzido, e menor ocorrência de erros na identificação dos domicílios sorteados. CONCLUSÕES: A construção de cadastro de domicílios por meio da criação de segmentos é vantajosa em relação à listagem completa de endereços, quando feita em favelas. Por ter se mostrado uma opção econômica e fácil de ser aplicada, constitui alternativa para a simplificação do processo de amostragem em áreas com as suas características de desorganização e adensamento de domicílios.

Não se extendem em discussão, nem comentarios, tampouco, relacionam suas verificações com o que já foi relatado sobre o assunto em trabalhos nacionais e estrangeiros, pelo fato de que, não se trata de um resultado definitivo e sim de atividades que irão proseguir. Os estudos sistematicos em torno da endemia esquistosomica foram executados em duas localidades diversas pela população e pela situação geografica e ecologica. Pontezinha é uma povoação de 1200 habitantes localizada proximo a um conjunto de charcos e lagõas de agua dôce onde pululam caramujos do tipo olivaceus de Spix, e apresenta uma taxa de infestação de 21,4% para individuos do sexo masculino, e de 14,7% para os do sexo feminino. A distribuição por grupos de idade mostra que a incidencia cresce até o grupo de 16 a 20 anos de idade, quando atinge a percentagem de 37,8%, para decrescer em seguida. Em Vitoria a incidencia foi maior nos indivíduos do sexo feminino, atingindo a taxa de 41,4%, dando o sexo masculino a taxa de 36,9%. Por idade a percentagem maxima é atingida pelo grupo de 11 a 15 anos. Vitoria é uma cidade de 1500 habitantes, construida á margem do rio Tapacurá, onde se encontram numerosos caramujos do tipo centimetralis Lutz. A divergencia de incidencia corre por conta dos habitos da população e pela utilização que ela faz do rio, sendo maior em Vitoria porque a proximidade do rio facilita o uso de suas aguas para banho e serviços domesticos, condicionando este ultimo fato, a maior infestação das mulheres. O estudo da frequencia da infestação dos caramujos por cercarias de diversos trematodios, permite suspeitar uma relação inversa entre a taxa de infestação e o diametro maximo atingido pelos caramujos, parecendo este fato confirmar os trabalhos de Vianna Martins sobre a identidade dos hospedeiros

A evolução foi satisfatória em 80% dos casos atendidos, nos demais casos (20% observou-se óbito da fêmea acometida. Do total de óbitos, os prolapsos vaginais foram responsáveis por 60% (3/5 e os prolapsos uterinos por 40% (2/5. A etiologia dos prolapsos não foi definida nos casos atendidos, sendo esses associados com o período pós-parto em sua maioria (56%, provavelmente associados com quadros de hipocalcemia, altas concentrações séricas de estrógeno e hipertonia uterina. Além disso, a predisposição genética não pode ser descartada.

  12. Salmonella Enteritidis em Aves: Retrospectiva no Brasil

    Full Text Available Salmonella Enteritidis (SE emergiu como um grande problema avícola e de saúde pública no Brasil a partir de 1993. Os estudos epidemiológicos, incluindo a fagotipagem e sonda complementar de rRNA, sugerem a entrada de SE no Brasil via importação de material genético avícola contaminado, provavelmente no final da década de 80. As taxas de crescimento da avicultura brasileira na década de 90 criaram condições favoráveis para a manutenção e proliferação da SE nos plantéis avícolas. Além disso, o uso indiscriminado de antibióticos em aves, particularmente as quinolonas, encorajou a manutenção de lotes positivos para SE. As cepas de SE isoladas de aves têm mostrado alta sensibilidade aos antibióticos de uso comum em avicultura, incluindo as quinolonas. Entretanto, o aumento da resistência antimicrobiana e multirresistência tem sido observado em cepas de origem humana. Os últimos levantamentos realizados no ano de 2001 continuam a mostrar que a SE em materiais avícolas é o principal sorovar responsável pelas infecções humanas. Embora as carcaças de frangos apresentem altas taxas de contaminação por SE, são os ovos e seus derivados - principalmente a maionese caseira - os principais responsáveis pelos surtos humanos. O uso de vacinas específicas em poedeiras e reprodutoras tem se mostrado uma ferramenta auxiliar no controle de SE. O procedimento mais indicado para o controle de SE na avicultura está na aquisição e produção de lotes livres do agente. As rações e matérias primas de origem animal parecem não ser tão importantes na perpetuação do problema de SE, porém, os roedores parecem ser reservatórios ambientais importantes de SE em granjas contaminadas.

    Prior studies have highlighted wide variation in emergency medical services (EMS) workplace safety culture across agencies. To determine the association between EMS workplace safety culture scores and patient or provider safety outcomes. We administered a cross-sectional survey to EMS workers affiliated with a convenience sample of agencies. We recruited these agencies from a national EMS management organization. We used the EMS Safety Attitudes Questionnaire (EMS-SAQ) to measure workplace safety culture and the EMS Safety Inventory (EMS-SI), a tool developed to capture self-reported safety outcomes from EMS workers. The EMS-SAQ provides reliable and valid measures of six domains: safety climate, teamwork climate, perceptions of management, working conditions, stress recognition, and job satisfaction. A panel of medical directors, emergency medical technicians and paramedics, and occupational epidemiologists developed the EMS-SI to measure self-reported injury, medical errors and adverse events, and safety-compromising behaviors. We used hierarchical linear models to evaluate the association between EMS-SAQ scores and EMS-SI safety outcome measures. Sixteen percent of all respondents reported experiencing an injury in the past three months, four of every 10 respondents reported an error or adverse event (AE), and 89% reported safety-compromising behaviors. Respondents reporting injury scored lower on five of the six domains of safety culture. Respondents reporting an error or AE scored lower for four of the six domains, while respondents reporting safety-compromising behavior had lower safety culture scores for five of the six domains. Individual EMS worker perceptions of workplace safety culture are associated with composite measures of patient and provider safety outcomes. This study is preliminary evidence of the association between safety culture and patient or provider safety outcomes.

  14. A infância em Piaget e o infantil em Freud: temporalidades e moralidades em questão

    Directory of Open Access Journals (Sweden)

    Maria Regina Maciel

    Full Text Available Resumo O presente artigo propõe uma abordagem comparativa entre as noções de infância em Jean Piaget e de infantil em Sigmund Freud, tomando como conceitos básicos a noção de tempo e de moral em ambos os autores. Sustenta-se ser possível afirmar, a partir de uma leitura da epistemologia genética, que a infância vai-se transformando à medida que agimos e conhecemos de acordo com estruturas cognitivas operatórias. No entanto, segundo a psicanálise, é possível nos remeter ao infantil, presente também na vida adulta. O infantil escapa à racionalidade que subjaz àquela noção de estrutura piagetiana. A permanência do infantil é fonte das experiências criativas e da instauração de um movimento permanente de subjetivação.

    1977-01-01

    A cotton-substantive, anionic, fluorescent whitening agent manufactured by several suppliers under various trade names e.g. Tinopal EMS, has been synthesized in radioactive form. Intubation of detergent or aqueous solution into rats resulted in little absorption from the intestinal tract as evidenced by low radioactivity in the urine and tissues. Most of the dose was excreted rapidly in the faeces. After parenteral administration to rats, the radioactivity was rapidly excreted in the faeces with small amounts remaining in tissues and organs. There was slight evidence of retention of radioactivity in the kidneys. Very small amounts of Tinopal EMS in detergent were absorbed through rat skin, but only when concentrations greater than those normally used by the consumer, together with occlusion of the skin were employed. Small amounts were absorbed through skin when applied in ethanol. It is concluded that the possibility of systemic toxic effects in man as a result of percutaneous absorption is remote

    Full Text Available Exposure to endogenous sex hormones has been reported as a risk factor for breast cancer. The <em>CYP11A1em> gene encodes the key enzyme that catalyzes the initial and rate-limiting step in steroid hormone synthesis. In this study, the associations between single nucleotide polymorphisms (SNPs in <em>CYP11A1em> and breast cancer susceptibility were examined. Six SNPs in <em>CYP11A1 em>were genotyped using the MassARRAY IPLEX platform in 530 breast cancer patients and 546 healthy controls. Association analyses based on a χ2 test and binary logistic regression were performed to determine the odds ratio (<em>OR> and 95% confidence interval (95% <em>CI> for each SNP. Two loci (rs2959008 and rs2279357 showed evidence of associations with breast cancer risk. The variant genotype C/T-C/C of rs2959008 was significantly associated with a decreased risk (age-adjusted<em> ORem>, 0.75; 95% <em>CI>, 0.58–0.96; <em>P em>= 0.023 compared with the wild-type TT. However, the homozygous TT variant of rs2279357 exhibited increased susceptibility to breast cancer (age-adjusted<em> ORem>, 1.44; 95% <em>CI>, 1.05–1.98; <em>P em>= 0.022. The locus rs2959003 also showed an appreciable effect, but no associations were observed for three other SNPs. Our results suggest that polymorphisms of <em>CYP11A1em> are related to breast cancer susceptibility in Han Chinese women of South China.

  7. Subsurface imaging by electrical and EM methods

    Energy Technology Data Exchange (ETDEWEB)

    1998-12-01

    This report consists of 3 subjects. 1) Three dimensional inversion of resistivity data with topography : In this study, we developed a 3-D inversion method based on the finite element calculation of model responses, which can effectively accommodate the irregular topography. In solving the inverse problem, the iterative least-squares approach comprising the smoothness-constraints was taken along with the reciprocity approach in the calculation of Jacobian. Furthermore the Active Constraint Balancing, which has been recently developed by ourselves to enhance the resolving power of the inverse problem, was also employed. Since our new algorithm accounts for the topography in the inversion step, topography correction is not necessary as a preliminary processing and we can expect a more accurate image of the earth. 2) Electromagnetic responses due to a source in the borehole : The effects of borehole fluid and casing on the borehole EM responses should thoroughly be analyzed since they may affect the resultant image of the earth. In this study, we developed an accurate algorithm for calculating the EM responses containing the effects of borehole fluid and casing when a current-carrying ring is located on the borehole axis. An analytic expression for primary vertical magnetic field along the borehole axis was first formulated and the fast Fourier transform is to be applied to get the EM fields at any location in whole space. 3) High frequency electromagnetic impedance survey : At high frequencies the EM impedance becomes a function of the angle of incidence or the horizontal wavenumber, so the electrical properties cannot be readily extracted without first eliminating the effect of horizontal wavenumber on the impedance. For this purpose, this paper considers two independent methods for accurately determining the horizontal wavenumber, which in turn is used to correct the impedance data. The 'apparent' electrical properties derived from the corrected impedance

    Stephen H. Thomas

    2012-01-01

    Full Text Available Patients, EMS systems, and healthcare regions benefit from Helicopter EMS (HEMS utilization. This article discusses these benefits in terms of specific endpoints utilized in research projects. The endpoint of interest, be it primary, secondary, or surrogate, is important to understand in the deployment of HEMS resources or in planning further HEMS outcomes research. The most important outcomes are those which show potential benefits to the patients, such as functional survival, pain relief, and earlier ALS care. Case reports are also important “outcomes” publications. The benefits of HEMS in the rural setting is the ability to provide timely access to Level I or Level II trauma centers and in nontrauma, interfacility transport of cardiac, stroke, and even sepsis patients. Many HEMS crews have pharmacologic and procedural capabilities that bring a different level of care to a trauma scene or small referring hospital, especially in the rural setting. Regional healthcare and EMS system's benefit from HEMS by their capability to extend the advanced level of care throughout a region, provide a “backup” for areas with limited ALS coverage, minimize transport times, make available direct transport to specialized centers, and offer flexibility of transport in overloaded hospital systems.
