The program was tasked with implementing time dependent analysis of charges particles into an existing finite element code with adaptive meshing, called Beam Optics Analyzer (BOA). BOA was initially funded by a DOE Phase II program to use the finite element method with adaptive meshing to track particles in unstructured meshes. It uses modern programming techniques, state-of-the-art data structures, so that new methods, features and capabilities are easily added and maintained. This Phase II program was funded to implement plasma simulations in BOA and extend its capabilities to model thermal electrons, secondary emissions, self magnetic field and implement a more comprehensive post-processing and feature-rich GUI. The program was successful in implementing thermal electrons, secondary emissions, and self magnetic field calculations. The BOA GUI was also upgraded significantly, and CCR is receiving interest from the microwave tube and semiconductor equipment industry for the code. Implementation of PIC analysis was partially successful. Computational resource requirements for modeling more than 2000 particles begin to exceed the capability of most readily available computers. Modern plasma analysis typically requires modeling of approximately 2 million particles or more. The problem is that tracking many particles in an unstructured mesh that is adapting becomes inefficient. In particular memory requirements become excessive. This probably makes particle tracking in unstructured meshes currently unfeasible with commonly available computer resources. Consequently, Calabazas Creek Research, Inc. is exploring hybrid codes where the electromagnetic fields are solved on the unstructured, adaptive mesh while particles are tracked on a fixed mesh. Efficient interpolation routines should be able to transfer information between nodes of the two meshes. If successfully developed, this could provide high accuracy and reasonable computational efficiency.

An assessment of the impact of the pet trade on five CITES-Appendix II case studies - Boa constrictor imperator

Montgomery, Chad E.; Boback, Scott M.; Reed, Robert N.; Frazier, Julius A.

2015-01-01

Boa constrictor is a wide ranging snake species that is common in the pet trade and is currently listed in CITES Appendix II. Hog Island boas, or Cayos Cochinos boas, are a dwarf, insular race of Boa constrictor imperator endemic to the Cayos Cochinos Archipelago, Honduras. Cayos Cochinos boas are prized in the international pet trade for their light pink dorsal coloration, as well as for being much smaller and more docile than mainland boas (Porras, 1999; Russo, 2007). The boa population in the Cayos Cochinos was heavily exploited for the pet trade from 1979 to 1993, and researchers reported finding no boas on the islands during a five day herpetological survey trip in the early 1990s (Wilson and CruzDiaz, 1993), leading to the speculation that the population had been extirpated (e.g., Russo, 2007). The Cayos Cochinos Archipelago Natural Marine Monument has been managed by the Honduran Coral Reef Foundation since 1994 and prohibits removal of boas from the area. Poaching for the pet trade continues today, although at a lower level. Due to the endemic nature of this island morph of B. c. imperator it is imperative that we understand the dynamics of the populations and the ongoing threats that could negatively impact their long-term survival.

Parallel selective pressures drive convergent diversification of phenotypes in pythons and boas.

Esquerré, Damien; Scott Keogh, J

2016-07-01

Pythons and boas are globally distributed and distantly related radiations with remarkable phenotypic and ecological diversity. We tested whether pythons, boas and their relatives have evolved convergent phenotypes when they display similar ecology. We collected geometric morphometric data on head shape for 1073 specimens representing over 80% of species. We show that these two groups display strong and widespread convergence when they occupy equivalent ecological niches and that the history of phenotypic evolution strongly matches the history of ecological diversification, suggesting that both processes are strongly coupled. These results are consistent with replicated adaptive radiation in both groups. We argue that strong selective pressures related to habitat-use have driven this convergence. Pythons and boas provide a new model system for the study of macro-evolutionary patterns of morphological and ecological evolution and they do so at a deeper level of divergence and global scale than any well-established adaptive radiation model systems. © 2016 John Wiley & Sons Ltd/CNRS.

Boa is a Neotropical genus of snakes historically recognized as monotypic despite its expansive distribution. The distinct morphological traits and color patterns exhibited by these snakes, together with the wide diversity of ecosystems they inhabit, collectively suggest that the genus may represent multiple species. Morphological variation within Boa also includes instances of dwarfism observed in multiple offshore island populations. Despite this substantial diversity, the systematics of the genus Boa has received little attention until very recently. In this study we examined the genetic structure and phylogenetic relationships of Boa populations using mitochondrial sequences and genome-wide SNP data obtained from RADseq. We analyzed these data at multiple geographic scales using a combination of phylogenetic inference (including coalescent-based species delimitation) and population genetic analyses. We identified extensive population structure across the range of the genus Boa and multiple lines of evidence for three widely-distributed clades roughly corresponding with the three primary land masses of the Western Hemisphere. We also find both mitochondrial and nuclear support for independent origins and parallel evolution of dwarfism on offshore island clusters in Belize and Cayos Cochinos Menor, Honduras.

Richter, Barbara; Kübber-Heiss, Anna; Weissenböck, Herbert

2008-05-06

A female boa (Boa constrictor) from a zoological collection was submitted for necropsy after sudden death. Prominent pathological findings included a diphtheroid colitis, endoparasitism, focal pneumonia and inclusion bodies typical for inclusion body disease (IBD). In the colon entamoebae were identified, which differed in size and distribution from Entamoeba invadens. Gene sequence analysis of the 18S ribosomal RNA revealed 100% similarity with an Entamoeba species from the African bullfrog (Pyxicephalus adspersus), probably Entamoeba ranarum. The snake was possibly immunosuppressed, and the source of infection remains unclear. This is the first report of an infection with an amphibian Entamoeba species associated with colitis in a snake.

BOA: Pipe-asbestos insulation removal robot system

Schempf, H.; Bares, J.; Mutschler, E.

1995-01-01

This paper describes the BOA system, a mobile pipe-external crawler used to remotely strip and bag (possibly contaminated) asbestos-containing lagging and insulation materials (ACLIM) from various diameter pipes in (primarily) industrial installations across the DOE weapons complex. The mechanical removal of ACLIM is very cost-effective due to the relatively low productivity and high cost involved in human removal scenarios. BOA, a mechanical system capable of removing most forms of lagging (paper, plaster, aluminum sheet, clamps, screws and chicken-wire), and insulation (paper, tar, asbestos fiber, mag-block) uses a circular cutter and compression paddles to cut and strip the insulation off the pipe through compression, while a HEPA-filter and encapsulant system maintain a certifiable vacuum and moisture content inside the system and on the pipe, respectively. The crawler system has been built and is currently undergoing testing. Key design parameters and performance parameters are developed and used in performance testing. Since the current system is a testbed, we also discuss future enhancements and outline two deployment scenarios (robotic and manual) for the final system to be designed and completed by the end of FY '95. An on-site demonstration is currently planned for Fernald in Ohio and Oak Ridge in Tennessee

The BOA beamline at the Swiss spallation neutron source SINQ at Paul Scherrer Institut is a flexible instrument used mainly for testing novel techniques and devices for neutron scattering and optics, but, due to the large and relatively homogeneous field of view, it can be successfully used for experiments in the field of neutron imaging. The beamline allows also for the exploitation of advanced imaging concepts such as polarized neutron imaging and diffractive neutron imaging. In this paper we present the characterization of the BOA beamline in the light of its neutron imaging capabilities. We show also the different techniques that can be employed there as user-friendly plugins for non-standard neutron imaging experiments

Ultrasound is a method for noninvasive diagnosis, their effectiveness in the diagnosis of liver disease has been described in snakes. The liver is the largest organ of the coelomic cavity of reptiles. Elongated and flattened. The caudal vena cava and portal vein divides the body into two lobes. The hepatic parenchyma is homogeneous hypoechoic echogenicity. The objective is to describe and to obtain reference images in the study of liver four snakes of Boa constrictor amarali, through an ultrasound and tomography. Physical restraint made for the ultrasound examination held in prone position, to compare the texture and mark the structures for the slices on CT. A linear multifrequency probe of 6-10 mHz was used. The anesthetic protocol for computed tomography consisted of isoflurane. In helical CT scanner, the animal was positioned in the prone position, and used continuous cross sections of 2 mm by 2. The ultrasound and CT examinations allowed the identification of liver contours as well as the definition and extension of the caudal vena cava and portal vein. Normal pattern recognition of CT aspect of the present study will be of help in the diagnosis of liver diseases in snakes (Boa constrictor amarali). (author)

FREUD, JUNG AND BOAS: THE PSYCHOANALYTIC ENGAGEMENT WITH ANTHROPOLOGY REVISITED.

Science.gov (United States)

Kenny, Robert

2015-06-20

Sigmund Freud's and C. G. Jung's turn to evolutionist anthropological material after 1909 is usually seen as a logical progression of their long-term interest in such material. It is also seen that they used this material ignorant of the significant challenges to the evolutionist paradigm underpinning such material, in particular the challenges led by Franz Boas. This paper argues otherwise: that both psychologists' turnings to such material was a new development, that neither had shown great interest in such material before 1909, and that their turnings to such material, far from being taken in ignorance of the challenges to evolutionist anthropology, were engagements with those challenges, because the evolutionist paradigm lay at the base of psychoanalysis. It argues that it is no coincidence that this engagement occurred after their return from America in 1909, where they had come into first-hand contact with the challenges of Franz Boas.

Full Text Available Boa constrictor is widely used in traditional communities in many different folk remedies and products derived from it are sold in public markets throughout northeastern Brazil and as its body fat has many different therapeutic indications as a folk remedy. The present work evaluates the antibacterial activity of the body fat from the snake Boa constrictor when employed either alone or in combination with antibiotics and discusses the ecological implications of the use of this traditional remedy. Oil (OBC was extracted from body fat located in the ventral region of B. constrictor using hexane as a solvent. The antibacterial activity of OBC was tested against standard as well as multi-resistant lines, either alone and in combination with antibiotics. OBC did not demonstrate any relevant antibacterial activity against standard or multidrug-resistant bacterial strains. OBC showed synergistic activity when combined with the aminoglycoside antibiotics. Our results indicate that the body fat of Boa constrictor does not possess bactericidal activity, from the clinical point of view, but when combined with an antibiotic, the fat demonstrated a significant synergistic activity.

2001-01-01

The objective of this task is to develop and demonstrate a mechanical, asbestos-removal system that can be remotely operated without a containment area. The technology, known as BOA, consists of a pipe-crawler removal head and a boom vehicle system with dual robots. BOA's removal head can be remotely placed on the outside of the pipe and can crawl along the pipe, removing lagging and insulation. The lagging and insulation is cut using a hybrid endmill water-jet cutter and then diced into 2-inch cube sections of ACM. These ACM sections are then removed from the pipe using a set of blasting fan- spray nozzles, vacuumed off through a vacuum hose, and bagged. Careful attention to vacuum and entrapment air flow ensures that the system can operate without a containment area while meeting local and federal standards for fiber count

In July 2015, fifteen research flights were conducted on a US Navy Twin Otter aircraft as part of the Biological and Oceanic Atmospheric Study (BOAS) campaign. The flights took place near the California coast at Monterey, to investigate the effects of sea surface temperature and algal blooms on oceanic particulate emissions, the diurnal mixing of urban pollution with other airmasses, and the impacts of biological aerosols on the California atmosphere. The aircraft's payload included an aerosol mass spectrometer (AMS), a differential mobility analyzer, a cloud condensation nuclei counter, a counterflow virtual impactor, a cloudwater collector, and two instruments designed to detect biological aerosols - a wideband integrated biological spectrometer and a SpinCon II - as well as a number of meteorology and aerosol probes, two condensation particle counters, and instruments to measure gas-phase CO, CO2, O3, and NOx. Here, we describe in depth the objectives and outcomes of BOAS and report preliminary results, primarily from the AMS. We detail the spatial characteristics and meteorological variability of speciated aerosol components over a strong and persistent bloom of Pseudo-Nitzschia, the harmful algae that cause 'red tide', and report newly identified AMS markers for biological particles. Finally, we compare these results with data collected during BOAS over urban, forested, and agricultural environments, and describe the mixing observed between oceanic and terrestrial airmasses.

Seasonal variation of serum biochemical values of Amazonian snakes (Boa constrictor constrictor kept in captivity

2012-11-01

Full Text Available In northern Brazil, the seasons are not well defined compared to the South and Southeast regions, due to a hot and humid equatorial climate with a rainy season, known as the Amazonian winter, and a period with less rain, known as the Amazonian summer. The goal of this study was to evaluate the biochemical variation of serum from the Amazon Boa constrictor by correlating the values with the seasons of the region. A biochemical analysis of the serum was performed (AST, ALT, LDH, ALP, calcium, uric acid, phosphorus, total protein, albumin and globulin using 31 individuals of Boa constrictor constrictor, which were kept in captivity. It was observed that eight of the ten parameters were higher in the winter compared to the summer (total protein, albumin, globulin, ALT, AST, ALP, LDH and calcium. The ALT, AST and calcium values had statistically significant differences for the summer and winter, while the other parameters appear to be influenced by seasonality. This was the first study of snakes kept in captivity that analyzed the serum chemistry profile of Boa constrictor constrictor from the state of Pará, Brazil.

Ecological specialization and morphological diversification in Greater Antillean boas.

Colonization of islands can dramatically influence the evolutionary trajectories of organisms, with both deterministic and stochastic processes driving adaptation and diversification. Some island colonists evolve extremely large or small body sizes, presumably in response to unique ecological circumstances present on islands. One example of this phenomenon, the Greater Antillean boas, includes both small (<90 cm) and large (4 m) species occurring on the Greater Antilles and Bahamas, with some islands supporting pairs or trios of body-size divergent species. These boas have been shown to comprise a monophyletic radiation arising from a Miocene dispersal event to the Greater Antilles, though it is not known whether co-occurrence of small and large species is a result of dispersal or in situ evolution. Here, we provide the first comprehensive species phylogeny for this clade combined with morphometric and ecological data to show that small body size evolved repeatedly on separate islands in association with specialization in substrate use. Our results further suggest that microhabitat specialization is linked to increased rates of head shape diversification among specialists. Our findings show that ecological specialization following island colonization promotes morphological diversity through deterministic body size evolution and cranial morphological diversification that is contingent on island- and species-specific factors. © 2016 The Author(s).

The CASL Level 1 Milestone CASL.P4.01, successfully completed in December 2011, aimed to 'conduct, using methodologies integrated into VERA, a detailed sensitivity analysis and uncertainty quantification of a crud-relevant problem with baseline VERA capabilities (ANC/VIPRE-W/BOA).' The VUQ focus area led this effort, in partnership with AMA, and with support from VRI. DAKOTA was coupled to existing VIPRE-W thermal-hydraulics and BOA crud/boron deposit simulations representing a pressurized water reactor (PWR) that previously experienced crud-induced power shift (CIPS). This work supports understanding of CIPS by exploring the sensitivity and uncertainty in BOA outputs with respect to uncertain operating and model parameters. This report summarizes work coupling the software tools, characterizing uncertainties, and analyzing the results of iterative sensitivity and uncertainty studies. These studies focused on sensitivity and uncertainty of CIPS indicators calculated by the current version of the BOA code used in the industry. Challenges with this kind of analysis are identified to inform follow-on research goals and VERA development targeting crud-related challenge problems.

Recent studies have described the detection and characterisation of new, snake specific arenaviruses in boas and pythons with inclusion body disease (IBD). The objective of this study was to detect arenaviral RNA in live snakes and to determine if these were associated with IBD in all cases. Samples for arenavirus detection in live animals were compared. Detected viruses were compared in order to understand their genetic variability. Esophageal swabs and whole blood was collected from a total of 28 boas and pythons. Samples were tested for arenaviral RNA by RT-PCR. Blood smears from all animals were examined for the presence of inclusion bodies. Internal tissues from animals that died or were euthanized during the study were examined for inclusions and via RT-PCR for arenaviral RNA. All PCR products were sequenced and the genomic sequences phylogenetically analysed. Nine live animals were found to be arenavirus-positive. Two additional snakes tested positive following necropsy. Five new arenaviruses were detected and identified. The detected viruses were named "Boa Arenavirus Deutschland (Boa Av DE) numbers 1-4" and one virus detected in a python (Morelia viridis) was named "Python Av DE1". Results from sequence analyses revealed considerable similarities to a portion of the glycoprotein genes of recently identified boid snake arenaviruses. Both oral swabs and whole blood can be used for the detection of arenaviruses in snakes. In most cases, but not in all, the presence of arenaviral RNA correlated with the presence of inclusions in the tissues of infected animals. There was evidence that some animals may be able to clear arenavirus infection without development of IBD. This is the first detection of arenaviruses in live snakes. The detection of arenaviruses in live snakes is of importance for both disease detection and prevention and for use in quarantine situations. The findings in this study support the theory that arenaviruses are the cause of IBD, but

Full Text Available Production of the watermelon is important in all regions of Brazil. However, productive and qualitative information for fruit of different cultivars grown in the same environment is still scarce, especially in the State of Roraima, a fact that makes it necessary to carry out studies in order to meet this need. As a result, this study aimed to evaluate the agronomic performance of watermelon cultivars produced in the Cerrado at Boa Vista, Roraima. The experiment was conducted at the Agua Boa Experimental Farm of Embrapa Roraima, from December 2013 to February 2014. The experimental design was of randomised blocks (DBC, with six replications. The treatments comprised six watermelon cultivars: Verena, Explore, Elisa, Juliane, Crimson Sweet and Crimson Sweet Super, for which the productive, physical, chemical and physicochemical characteristics of the fruit were evaluated. There was no difference between cultivars in yield, number of fruit ha-1 or the number of fruit with a weight of between 6 and 9 kg. The cultivars differed as to physical characteristics (weight, size and number of seeds per fruit. There were differences between cultivars for all the chemical and physicochemical characteristics of the fruit. The cultivar Elisa displayed the highest levels for total soluble solids (12.58 °Brix. Fruits of the cultivars Explore and Crimson Sweet Super showed the greatest ratio between total soluble solids and titratable acidity. The fruits of the cultivars Explore and Elisa had the highest pH. The conditions of soil and climate in the Cerrado at Boa Vista favour the productive and qualitative characteristics of the cultivars being analysed. = A produção de melancia é consolidada em todas as regiões do Brasil. Porém, as informações sobre produtividade e qualidade dos frutos, de diferentes cultivares no mesmo ambiente, ainda são tímidas, sobretudo em Roraima, tornando necessária a realização de estudos para suprir essa carência.

Ultrasound is a method for noninvasive diagnosis, their effectiveness in the diagnosis of liver disease has been described in snakes. The liver is the largest organ of the coelomic cavity of reptiles. Elongated and flattened. The caudal vena cava and portal vein divides the body into two lobes. The hepatic parenchyma is homogeneous hypoechoic echogenicity. The objective is to describe and to obtain reference images in the study of liver four snakes of Boa constrictor amarali, through an ultrasound and tomography. Physical restraint made for the ultrasound examination held in prone position, to compare the texture and mark the structures for the slices on CT. A linear multifrequency probe of 6-10 mHz was used. The anesthetic protocol for computed tomography consisted of isoflurane. In helical CT scanner, the animal was positioned in the prone position, and used continuous cross sections of 2 mm by 2. The ultrasound and CT examinations allowed the identification of liver contours as well as the definition and extension of the caudal vena cava and portal vein. Normal pattern recognition of CT aspect of the present study will be of help in the diagnosis of liver diseases in snakes (Boa constrictor amarali). (author)

Full Text Available Grapevine plants have been grown in different tropical regions of Brazil. In the state of Roraima, this culture was introduced commercially in 2005 in Boa Vista. Unlike temperate regions, tropical regions present thermal conditions for grape production throughout the year. To evaluate the climatic characteristics on different periods of the year, it can be used different indices. The objective of this study was to characterize climate suitability of Boa Vista, Roraima, Brazil, for grapevine cultivation at different months of the year. For climate classification it was used the Geoviticulture Multicriteria Climatic Classification System (CCM, which is composed by three indices: Heliothermal (IH, Cool Night (IF, and Drought (IS. It was also used the Zuluaga Index (IZ, to assess the risk of incidence of fungal diseases on the vine, especially in relation to the incidence of downy mildew (Plasmopara viticola, one of the main grapevine diseases in humid regions. Based on the evaluated indices, it was found that the most favorable period for grape production goes from October to March because of the lower values of rainfall. During the other months, it can be employed branch pruning without fruit production, as occurs in other tropical locations of Brazil. =A videira tem sido cultivada em diferentes regiões tropicais do Brasil. No estado de Roraima, ela foi implantada comercialmente em 2005 em Boa Vista.

Schempf, H.; Bares, J.E.

1995-01-01

Based on several key design criteria and site visits, we developed a Robot design and built a system which automatically strips the lagging and insulation from the pipes, and encapsulates them under complete vacuum operation. The system can operate on straight runs of piping in horizontal or vertical orientations. Currently we are limited to four-inch diameter piping without obstacles as well as a somewhat laborious emplacement and removal procedure. Experimental results indicated that the current robotic abatement process is sound yet needs to be further expanded and modified. One of the main discoveries was that a longitudinal cut to fully allow the paddles to dig in and compress the insulation off the pipe is essential. Furthermore, a different cutting method might be explored to alleviate the need for a deeper cut and to enable a combination of certain functions such as compression and cutting. Unfortunately due to a damaged mechanism caused by extensive testing, we were unable to perform vertical piping abatement experiments, but foresee no trouble in implementing them in the next proposed Phase. Other encouraging results have BOA removing asbestos at a rate of 4-5 ft./h compared to 3 ft./h for manual removal of asbestos with a 3-person crew. However, we feel confident that we can double the asbestos removal rate by improving cutting speed, and increasing the length of the BOA robot. The containment and vacuum system on BOA is able to achieve the regulatory requirement for airborne fiber emissions of 0.01 fibers/ccm/8-hr. shift. Currently, BOA weighs about 117 pounds which is more than a human is permitted to lift overhead under OSHA requirements (i.e., 25 pounds). We are considering designing the robot into two components (i.e., locomotor section and cutter/removal section) to aid human installation as well as incorporating composite materials. A more detailed list of all the technical modifications is given in this topical report

Full Text Available A reprodução faz parte do ciclo de vida dos animais permitindo a perpetuação e a conservação das espécies. Em serpentes, existe uma escassez de informações técnicas a respeito do ciclo reprodutivo. Este estudo teve o objetivo de avaliar o aparelho reprodutivo por meio da ultrassonografia em serpentes vivíparas cativas da família Boidae, permitindo diagnosticar as diferentes fases reprodutivas. Foram avaliadas ultrassonograficamente onze serpentes adultas de quatro espécies da família Boidae: Eunectes murinus, Boa constrictor constrictor, Corallus hortulanus e Epicrates cenchria pertencentes ao acervo do Museu Biológico do Instituto Butantan, São Paulo Brasil. Para a avaliação ultrassonográfica, as serpentes foram contidas fisicamente com gancho herpetológico e depois manualmente por aproximadamente 15 minutos. A avaliação foi feita aplicando-se gel acústico sobre a pele e posicionando o transdutor na linha lateral-ventral direita e esquerda, em região medial do corpo em sentido crânio-caudal. O exame ultrassonográfico permitiu avaliar todo o ciclo reprodutivo nas serpentes. Nas avaliações ultrassonográficas das fêmeas pode-se definir as fases de desenvolvimento ovariano e ovidutal. Os folículos ovarianos durante a fase pré-vitelogênica foram visualizados como homogêneos e anecogênicos, em forma de "cacho de uva". Já na fase vitelogênica, os folículos estavam maiores e mais ecogênicos seguidos uns dos outros, como um "colar de pérolas". Quando não houve cópula, os folículos foram reabsorvidos dentro do ovário retornando a fase pré-vitelogênica. Na fase pós ovulatória foram visualizados três estágios bem definidos de desenvolvimento fetal dentro do oviduto: 1 logo após a ovulação (e fecundação, somente o vitelo foi visualizado; 2 o vitelo ocupava 60% e o feto 40% do ovo e 3 o feto estava formado e não havia vitelo.

The purpose of this study was to evaluate the radiological procedures used at the odontologic clinics of Boa Vista, Roraima-Brazil. The following parameters were recorded: field diameter, half value layer, total filtration, discrepancy between the preset and the applied kilovoltage and exposure time. Dose to the patient's skin from radiography of the upper molar tooth was also estimated. The results showed that 78% of the inspected units had field diameters larger than 6,0 cm, which is outside the limits recommended by the Brazilian Health Ministry. The results also showed that 14% of the equipment presented a discrepancy of more than 10% between preset and applied kilovoltage. On the other hand, the discrepancy between preset and applied exposure time is higher than 10% in 70% of the tested units. The total filtration of 77% units is lower than 1,5 mm of Al, a value recommended by the Brazilian Health Ministry for equipment that operates in the range of 50 kV to 70 kV. The survey also indicates that for 35% of the units the entrance dose in high than 3,5 mGy that is the reference value established by the Brazilian Health Ministry for dental radiography with film type. It was observed that the majority of the clinics use neither aprons nor collars for patients and that films are processed manually, without controlling temperature or processing time. Based on the results obtained it is strongly recommended that a quality control program be implemented in dental radiological clinics in Boa Vista, Roraima. (author)

Nature/nurture and the anthropology of Franz Boas and Margaret Mead as an agenda for revolutionary politics

Directory of Open Access Journals (Sweden)

Sidney M. Greenfield

2001-12-01

Full Text Available There is much more involved in the nature/nurture debate than an abstract theoretical disagreement among dispassionate scientists. Each side of the debate leads logically to significantly different views of the social order and holds different implications for social policy. In this paper I shall argue that Boas' Anthropology with its emphasis on cultural relativism was as much a social and political agenda as it was a scientific theory. The positions on public policy issues he opposed were informed (and rationalized by what its advocates claimed to be science. To be able to counter the discriminatory policy proposals that followed from this science, it was necessary for Boas both to challenge its validity and then replace it with an alternative that would support a more liberal political agenda. This chapter of anthropology's history gains relevance in today's context as neoevolutionary, reductionist theories once more provide "scientific" support for conservative, separatist and often discriminatory social policies.O debate natureza/cultura é muito mais do que um desentendimento teórico e abstrato entre cientistas desapaixonados. Cada lado do debate leva a visões diferentes da ordem social e traz implicações diferentes para políticas sociais. Neste artigo, sugiro que a Antropologia de Boas, com sua ênfase no relativismo cultural, tanto quanto uma teoria científica, foi um programa social e político. As posturas de política pública às quais ele se opunha eram informadas (e racionalizadas por algo apresentado por seus proponentes como ciência. Para combater as propostas discriminatórias que decorriam desta ciência, cabia a Boas desafiar sua validade e substituí-la por uma alternativa que daria apoio a uma agenda política mais liberal. Esse capítulo da história da antropologia assume maior relevância no contexto atual em que teorias néo-evolucionistas e reducionistas mais uma vez fornecem uma base "científica" para pol

Full Text Available Many snakes are able to use their chemosensory system to detect scent of conspecifics, which is important in many social contexts. Age discrimination based on chemical cues may be especially important to ensure access to sexually mature potential partners. In this study, we used 24 individual Boa constrictor snakes (12 adults mature and 12 non-mature individuals that had been captured in different areas of Ecuador, and were maintained in captivity at the Vivarium of Quito. We used tongue-flick experiments to examine whether these snakes were able to discriminate between scents from mature and non-mature individuals. Results showed that B. constrictor snakes used chemical cues to recognize conspecifics and that the scent of individuals of different ages elicited chemosensory responses of different magnitudes. The scents from adult conspecifics elicited the quickest and highest chemosensory responses (i.e., short latency times and high tongue-flick rates, although we did not find differential responses to scent of males and females. The magnitude of the responses was lower to scent of sub adult individuals, and then even lower to scent of juvenile snakes, but in all cases the scent of snakes was discriminated from a blank control. We discuss the potential chemical mechanisms that may allow age recognition and its implications for social and sexual behavior of this snake species.Muchas serpientes son capaces de usar su sistema quimiosensorial para detectar el olor de individuos coespecíficos, lo que es importante en muchos contextos sociales.

Full Text Available O projeto dos jardins da Quinta da Boa Vista foi apresentado ao Imperador D. Pedro II por Auguste François-Marie Glaziou em 1868 e as obras, efetivamente, iniciadas em 1872. Construídos para o deleite não só da família imperial, seus convidados e das pessoas que moravam no interior da propriedade, o acesso era aberto à população em geral aos domingos, talvez, numa tentativa de acalmar os ânimos revolucionários do povo, tal qual acontecera na Inglaterra nos séculos anteriores. Inspirado nos jardins paisagísticos franceses, aliado aos conhecimentos das matas nacionais, o projeto executado por Glaziou para a Quinta da Boa Vista produz grande impacto nos frequentadores devido aos contrastes proporcionados. A utilização maciça de vegetação arbórea — principalmente em suas extremidades — produz um distanciamento visual da cidade que pode promover uma evasão tanto da situação geográfica como de seus problemas, gerando uma sensação de conforto e bem-estar, característica de vários parques da época.

(Abstr. Appl. Anal. 2012:680340, 2012). We establish the moments of the operator and a Voronvskaja type asymptotic theorem and then proceed to studying the convergence of the operators with the help of Lipschitz type space and weighted modulus of continuity. Next, we obtain a direct approximation theorem with the aid of unified Ditzian-Totik modulus of smoothness. Furthermore, we study the approximation of functions whose derivatives are locally of bounded variation.

2017-01-01

Recent studies of animal personality have focused on its proximate causation and ecological and evolutionary significance in particular, but the question of its development was largely overlooked. The attributes of personality are defined as between-individual differences in behaviour, which are consistent over time (differential consistency) and contexts (contextual generality) and both can be affected by development. We assessed several candidates for personality variables measured in various tests with different contexts over several life-stages (juveniles, older juveniles, subadults and adults) in the Northern common boa. Variables describing foraging/feeding decision and some of the defensive behaviours expressed as individual average values are highly repeatable and consistent. We found two main personality axes—one associated with foraging/feeding and the speed of decision, the other reflecting agonistic behaviour. Intensity of behaviour in the feeding context changes during development, but the level of agonistic behaviour remains the same. The juveniles and adults have a similar personality structure, but there is a period of structural change of behaviour during the second year of life (subadults). These results require a new theoretical model to explain the selection pressures resulting in this developmental pattern of personality. We also studied the proximate factors and their relationship to behavioural characteristics. Physiological parameters (heart and breath rate stress response) measured in adults clustered with variables concerning the agonistic behavioural profile, while no relationship between the juvenile/adult body size and personality concerning feeding/foraging and the agonistic behavioural profile was found. Our study suggests that it is important for studies of personality development to focus on both the structural and differential consistency, because even though behaviour is differentially consistent, the structure can change.

Traffic informatization has significantly improved the transport efficiency and the internet of things (IoT) bring more new technology and new methods for the development of traffic informatization. The internet of vehicles (IoV) is subsequently generated and is now under developing. However, it has some technical problems in the application process, such as monitoring the detail component of vehicle. In this paper, a technology is proposed that is accessible the small parts of traffic equipment through BOA technology. If the hardware itself has embedded control interface, can the remote monitor be used to revise the components parameters through integration BOA with the interface. By this way, the whole or parts of the equipments can be monitored and optimized by integrating with the CAN bus. It can even reach a wide range of remoting access and monitoring parameters by setting up separated virtual IPv6 address for the BOA. Finally, the example of the controlled video surveillance with the BOA technology is used to demonstrate the feasibility of this technology.%交通信息化提高了交通效率,物联网技术为交通信息化的发展带来更多新技术、新方法,由此产生了“车联网技术”.物联网技术是一种在发展的新技术,故此车联网技术在应用过程中存在一些技术障碍,如车辆细部部件的监控等.本文提出一种通过BOA技术进行交通设备部件访问的服务技术,如果硬件本身具有嵌入式控制接口,通过BOA技术与这种接口集成可以远程对部件进行监控与参数修改.这样BOA通过CAN总线集成的操作可以对设备整体进行全部部件监控和更多的优化操作,甚至可以对BOA设置单独的虚拟IPv6地址,达到更大范围内的远程参数获取与监控.最后,通过具有BOA技术的可控视频监控实例证明,此种技术可行.

The purpose of this study was to evaluate the radiological procedures used at the odontologic clinics of Boa Vista, Roraima-Brazil. The following parameters were recorded: field diameter, half value layer, total filtration, discrepancy between the preset and the applied kilovoltage and exposure time. Dose to the patient's skin from radiography of the upper molar tooth was also estimated. The results showed that 78% of the inspected units had field diameters larger than 6,0 cm, which is outside the limits recommended by the Brazilian Health Ministry. The results also showed that 14% of the equipment presented a discrepancy of more than 10% between preset and applied kilovoltage. On the other hand, the discrepancy between preset and applied exposure time is higher than 10% in 70% of the tested units. The total filtration of 77% units is lower than 1,5 mm of Al, a value recommended by the Brazilian Health Ministry for equipment that operates in the range of 50 kV to 70 kV. The survey also indicates that for 35% of the units the entrance dose in high than 3,5 mGy that is the reference value established by the Brazilian Health Ministry for dental radiography with film type. It was observed that the majority of the clinics use neither aprons nor collars for patients and that films are processed manually, without controlling temperature or processing time. Based on the results obtained it is strongly recommended that a quality control program be implemented in dental radiological clinics in Boa Vista, Roraima. (author)

Mandibular osteosynthesis in a Boa constrictor snake

Jorge Luiz Costa Castro

2014-02-01

Full Text Available Nowadays are observed an increase in the finding of certain wild animals in urban areas, due to environmental changes caused by deforestation and economic use of natural areas. It causes disappearance of usual prey and forces these animals, including snakes, to migrate to urban areas, becoming vulnerable to injuries caused by aggressions, car accidents and capture. Mandibular and maxillar fractures are common in many animal species, representing about 3-6% of all bone fractures in dogs and cats. Mandibular trauma usually occurs as a result of fights, car accidents and improper handling and/or restraint, and fractures can be closed or open, clean or contaminated. The jaw is a flat bone with differences from the long bones that should be taken into consideration for successful treatment, being minimal muscle coverage and need to maintain occlusion factors that influence the definition of the best ostheosynthesis method. The methods of stabilization include using intramedullary pins, wires, external skeletal fixation, bone plate, and acrylic resin. Conventional bone plates are efficient but related to some complications, such as the necessity of muscular elevation and high risk of injuries to mandibular structures. This article describes the successful results of the application of plate and screws in the ostheosynthesis of a mandibular fracture in a female Boa constrictor snake with weight of 8.0 kg and length of 1.80 m, at the RIOZOO Foundation (Rio de Janeiro, RJ, Brazil.

Toward a Tree-of-Life for the boas and pythons: multilocus species-level phylogeny with unprecedented taxon sampling.

Graham Reynolds, R; Niemiller, Matthew L; Revell, Liam J

2014-02-01

Snakes in the families Boidae and Pythonidae constitute some of the most spectacular reptiles and comprise an enormous diversity of morphology, behavior, and ecology. While many species of boas and pythons are familiar, taxonomy and evolutionary relationships within these families remain contentious and fluid. A major effort in evolutionary and conservation biology is to assemble a comprehensive Tree-of-Life, or a macro-scale phylogenetic hypothesis, for all known life on Earth. No previously published study has produced a species-level molecular phylogeny for more than 61% of boa species or 65% of python species. Using both novel and previously published sequence data, we have produced a species-level phylogeny for 84.5% of boid species and 82.5% of pythonid species, contextualized within a larger phylogeny of henophidian snakes. We obtained new sequence data for three boid, one pythonid, and two tropidophiid taxa which have never previously been included in a molecular study, in addition to generating novel sequences for seven genes across an additional 12 taxa. We compiled an 11-gene dataset for 127 taxa, consisting of the mitochondrial genes CYTB, 12S, and 16S, and the nuclear genes bdnf, bmp2, c-mos, gpr35, rag1, ntf3, odc, and slc30a1, totaling up to 7561 base pairs per taxon. We analyzed this dataset using both maximum likelihood and Bayesian inference and recovered a well-supported phylogeny for these species. We found significant evidence of discordance between taxonomy and evolutionary relationships in the genera Tropidophis, Morelia, Liasis, and Leiopython, and we found support for elevating two previously suggested boid species. We suggest a revised taxonomy for the boas (13 genera, 58 species) and pythons (8 genera, 40 species), review relationships between our study and the many other molecular phylogenetic studies of henophidian snakes, and present a taxonomic database and alignment which may be easily used and built upon by other researchers

Full Text Available La relación entre la fluorescencia variable y la fluorescencia máxima (Fv/Fm de las comunidades de algas se ha utilizado comúnmente como una medida de la eficiencia fotosintética del fitoplancton. Dicha eficiencia puede estar afectada por la localización de los ambientes acuáticos en distintas provincias limnológicas. En este trabajo se quiso establecer la diferencia en la relación Fv/Fm entre el lago Boa (150 msnm, Amazonía colombiana y el lago Guatavita (3000 msnm, cordillera oriental de los Andes colombianos. Los promedios de las eficiencias medidas fueron en general bajos (0,212 a 0,367 y 0,089 a 0,32 en los lagos Boa y Guatavita, respectivamente, lo que señala estrés fisiológico para las algas. La eficiencia fue mayor en aguas intermedias y presentó cambios fuertes entre épocas de muestreo y entre ecosistemas. En aguas superficiales se presentó fotoinhibición, la cual fue más fuerte en Guatavita. La eficiencia fotosintética fue menor en el lago andino debido posiblemente a diferencias climáticas, de altura sobre el nivel del mar y de estratificación. Durante los ensayos de laboratorio se observó que la eficiencia disminuyó con el tiempo, lo cual pudo deberse a una aclimatación de las algas a la oscuridad. Los datos de laboratorio confirmaron que el fitoplancton epilimnético del lago Guatavita estuvo fotoinhibido en la época de estratificación.Commonly relation between variable fluorescence and maximum fluorescence (Fv/Fm of the algae community has been utilized like a measure of the phytoplanktonic photosynthetic efficiency.

2015-02-01

Full Text Available Body size is highly correlated with metabolism, which in turn influences physiological rates such as heart rate. In general, heart rate is negatively influenced by the size of animal's body, but there is insufficient data corroborating this pattern in snakes. This study evaluated how body size affects heart rate in captive Boa constrictor Linnaeus, 1758. We measured the heart rate of 30 snakes using digital palpation and evaluated how this rate is influenced by body mass and sex using Analysis of Covariance (ANCOVA. The heart rate of the snakes was 58.8 ± 6.7 bpm (beats per minute. Body size, estimated as log-transformed body mass, negatively influenced heart rate (F1,28 = 10.27, p = 0.003, slope = -0.00004, R2 = 0.27, but sex had no effect (F1,27 = 0.07, p = 0.80. In conclusion, this result corroborates the negative relationship between body size and heart rate for snakes and reinforces the influence of related metabolic characteristics, such as body size, on the physiological parameters of snakes.

2012-12-01

Full Text Available Many snakes are able to use their chemosensory system to detect scent of conspecifics, which is important in many social contexts. Age discrimination based on chemical cues may be especially important to ensure access to sexually mature potential partners. In this study, we used 24 individual Boa constrictor snakes (12 adults mature and 12 non-mature individuals that had been captured in different areas of Ecuador, and were maintained in captivity at the Vivarium of Quito. We used tongue-flick experiments to examine whether these snakes were able to discriminate between scents from mature and non-mature individuals. Results showed that B. constrictor snakes used chemical cues to recognize conspecifics and that the scent of individuals of different ages elicited chemosensory responses of different magnitudes. The scents from adult conspecifics elicited the quickest and highest chemosensory responses (i.e., short latency times and high tongue-flick rates, although we did not find differential responses to scent of males and females. The magnitude of the responses was lower to scent of sub adult individuals, and then even lower to scent of juvenile snakes, but in all cases the scent of snakes was discriminated from a blank control. We discuss the potential chemical mechanisms that may allow age recognition and its implications for social and sexual behavior of this snake species.

Here we report the first witnessed attack on a marmoset by a constrictor snake. The incident occurred mid-morning in a gallery forest within an altered landscape of the Cerrado region of central Brazil and refers to a fatal attack by a Boa constrictor on two juvenile black-tufted-ear marmosets (Callithrix penicillata) simultaneously. The snake captured both individuals at a height of ~ 4 m while a group of eight marmosets traveled through the subcanopy. The actual strike was not seen. After 2 min, the boa fell to the ground with both marmosets in its coils and proceeded to kill one animal at a time through constriction. Two adult marmosets immediately descended to where the snake held its victims on the ground and attacked it. The snake showed no apparent reaction, and after ~ 1-2 min, the adults rejoined the remaining group members that were mobbing and vocalizing from 5 to 6 m above. The group left the scene ~ 7 min after the onset of the attack and was not seen again. The snake loosened its coils 10 min after its initial strike, left the two carcasses on the ground and stayed behind a nearby tree. Thus, we are not sure if the victims were in fact ingested. This report confirms that marmosets are vulnerable to boid snakes and capable of highly organized and cooperative antipredation behavior. It also suggests that snakes pose a greater threat to callitrichids than previously thought.

Giant Constrictors: Biological and Management Profiles and an Establishment Risk Assessment for Nine Large Species of Pythons, Anacondas, and the Boa Constrictor, estimates the ecological risks associated with colonization of the United States by nine large constrictors. The nine include the world's four largest snake species (Green Anaconda, Eunectes murinus; Indian or Burmese Python, Python molurus; Northern African Python, Python sebae; and Reticulated Python, Broghammerus reticulatus), the Boa Constrictor (Boa constrictor), and four species that are ecologically or visually similar to one of the above (Southern African Python, Python natalensis; Yellow Anaconda, Eunectes notaeus; DeSchauensee's Anaconda, Eunectes deschauenseei; and Beni Anaconda, Eunectes beniensis). At present, the only probable pathway by which these species would become established in the United States is the pet trade. Although importation for the pet trade involves some risk that these animals could become established as exotic or invasive species, it does not guarantee such establishment. Federal regulators have the task of appraising the importation risks and balancing those risks against economic, social, and ecological benefits associated with the importation. The risk assessment quantifies only the ecological risks, recognizing that ecosystem processes are complex and only poorly understood. The risk assessment enumerates the types of economic impacts that may be experienced, but leaves quantification of economic costs to subsequent studies. Primary factors considered in judging the risk of establishment were: (1) history of establishment in other countries, (2) number of each species in commerce, (3) suitability of U.S. climates for each species, and (4) natural history traits, such as reproductive rate and dispersal ability, that influence the probability of establishment, spread, and impact. In addition, the risk assessment reviews all management tools for control of invasive giant

Full Text Available The Roraima viticulture began in 2003 with the creation of the Vale do Rio Branco project, in which the cultivation of grapes was enlarged for a commercial production. However, no information has been found in literature  about the mineral content of grapes produced. Considering the essentiality and importance of this information for human nutrition, quantification of species K by flame photometry and Ca, Fe and Zn by flame atomic absorption spectrometry in pulps of grapes of the Isabel, Vitis labrusca L. variety, cultivated in Boa Vista/RR has been realized, as well as determination of the physical characteristics of the grape bunches and berries. The determinations´ results indicate that K had the highest concentration, followed by Ca, Fe and Zn, being similar to the data, described in other literature sources, except for Ca, which showed smaller, indicating an intervention demand of culture methods employed to optimize the absorption of this species by vines. The consumption of Isabel grape can contribute to the achievement of the adequate intake recommendations of mineral elements. The results of the physical characterization let us classify Isabel grape bunches to very small, loose and green stalks. Overall, this study reveals new data about the physical characteristics and mineral composition present in Isabel grape grown in Boa Vista/RR.

Full Text Available En el presente trabajo se experimentó sobre la habilidad de Boa constrictor occidentalis para discriminar y seguir olores feromonales conespecíficos y heteroespecíficos. Las hembras presentaron elevada frecuencia de extrusiones de lengua hacia los estímulos de olor de piel de macho, piel de hembra y glándula de hembra, mostrando un mayor desplazamiento hacia el estímulo piel de hembra. Los machos respondieron con un incremento en el número de lengüeteos y búsqueda activa de los rastros frente a las secreciones de macho. Ambos sexos manifestaron preferencia por los olores conespecíficos aumentando la intensidad del lengüeteo y el seguimiento activo de rastros, mientras que exhibieron una marcada disminución de la frecuencia de extrusiones de lengua y escaso desplazamiento frente al estímulo heteroespecífico. Los resultados sugieren la estrecha relación existente entre la identificación de un estímulo mediante el lengüeteo y la actividad de rastreo. The ability in adult Boa constrictor occidentalis to discriminate between species and sexes and follow pheromonal trails was tested. Females presented elevated tongue flick rate (T.F.R. to male skin odor, female skin odor and female cloacal secretion. Trailing activity was higher to female skin odor. Males answered with elevated T.F.R. and exhibited active movements and searching of trails to their own secretions —male skin and male cloacal musk—. Both sexes had preferences to conespecific stimuli showing higher T.F.R. and active trailing while they were not interested in heterospecific trails presenting lower T.F.R. and limited movements. Results suggest the relationship between stimuli recognition by tongue flicking and trailing activity.

To determine the ultrasonographic features of the coelomic organs of healthy snakes belonging to the Boidae and Pythonidae families. 16 ball pythons (Python regius; 7 males, 8 females, and 1 sexually immature), 10 Indian rock pythons (Python molurus molurus; 5 males, 4 females, and 1 sexually immature), 12 Python curtus (5 males and 7 females), and 8 boa constrictors (Boa constrictor imperator; 4 males and 4 females). All snakes underwent complete ultrasonographic evaluation of the coelomic cavity; chemical restraint was not necessary. A dorsolateral approach to probe placement was chosen to increase image quality and to avoid injury to the snakes and operators. Qualitative and quantitative observations were recorded. The liver, stomach, gallbladder, pancreas, small and large intestines, kidneys, cloaca, and scent glands were identified in all snakes. The hemipenes were identified in 10 of the 21 (48%) male snakes. The spleen was identified in 5 of the 46 (11%) snakes, and ureters were identified in 6 (13%). In 2 sexually immature snakes, the gonads were not visible. One (2%) snake was gravid, and 7 (15%) had small amounts of free fluid in the coelomic cavity. A significant positive correlation was identified between several measurements (diameter and thickness of scent glands, gastric and pyloric walls, and colonic wall) and body length (snout to vent) and body weight. The study findings can be used as an atlas of the ultrasonographic anatomy of the coelomic cavity in healthy boid snakes. Ultrasonography was reasonably fast to perform and was well tolerated in conscious snakes.

Co-infecting Reptarenaviruses Can Be Vertically Transmitted in Boa Constrictor.

Directory of Open Access Journals (Sweden)

Saskia Keller

2017-01-01

Full Text Available Boid inclusion body disease (BIBD is an often fatal disease affecting mainly constrictor snakes. BIBD has been associated with infection, and more recently with coinfection, by various reptarenavirus species (family Arenaviridae. Thus far BIBD has only been reported in captive snakes, and neither the incubation period nor the route of transmission are known. Herein we provide strong evidence that co-infecting reptarenavirus species can be vertically transmitted in Boa constrictor. In total we examined five B. constrictor clutches with offspring ranging in age from embryos over perinatal abortions to juveniles. The mother and/or father of each clutch were initially diagnosed with BIBD and/or reptarenavirus infection by detection of the pathognomonic inclusion bodies (IB and/or reptarenaviral RNA. By applying next-generation sequencing and de novo sequence assembly we determined the "reptarenavirome" of each clutch, yielding several nearly complete L and S segments of multiple reptarenaviruses. We further confirmed vertical transmission of the co-infecting reptarenaviruses by species-specific RT-PCR from samples of parental animals and offspring. Curiously, not all offspring obtained the full parental "reptarenavirome". We extended our findings by an in vitro approach; cell cultures derived from embryonal samples rapidly developed IB and promoted replication of some or all parental viruses. In the tissues of embryos and perinatal abortions, viral antigen was sometimes detected, but IB were consistently seen only in the juvenile snakes from the age of 2 mo onwards. In addition to demonstrating vertical transmission of multiple species, our results also indicate that reptarenavirus infection induces BIBD over time in the offspring.

Full Text Available Pesquisas indicam que o processo de desflorestamento na Amazônia está associado à abertura de estradas, uma vez que favorece o fluxo migratório, a ocupação de terras e a exploração de madeiras. O objetivo deste trabalho foi analisar o desflorestamento no entorno (20 km da rodovia BR-174 para um período de 30 anos (1978-2008. Foram utilizadas imagens LANDSAT, dados do INPE/PRODES, dados cartográficos e econômicos e trabalhos de campo. Os resultados demonstraram um crescimento do desflorestamento, passando de 622,15 km2 em 1978 para 2.618,58 km2 em 2008. As principais atividades econômicas dos municípios por onde passa a BR-174, exceto Manaus, estão associadas à agropecuária. Em Manaus, o desflorestamento ocorre principalmente na área urbana. Ainda que a construção da BR-174 esteja associada a processos de desflorestamento, a rodovia possui grande importância para a região, pois foi responsável pela ligação terrestre entre duas capitais do norte do país (Manaus/AM e Boa Vista/RR e possibilitou formar comunidades onde são desenvolvidas atividades econômicas e sociais. A criação de projetos de desenvolvimento sustentável é o grande desafio dos governos locais, para agregar valor aos empreendimentos existentes e desenvolver novos modelos de uso e ocupação na região.

The "pseudo-craniovertebral articulation" in the deep-sea fish Stomias boa (Teleostei: Stomiidae).

2008-05-01

Many predatory deep-sea fishes show highly specialized modifications of their feeding apparatus, e.g., elongate jaws studded with long daggerlike teeth, often combined with a very distensible stomach, to be capable of swallowing relatively large prey. These striking features can be observed in members of the marine teleost family Stomiidae. The present study gives a detailed morphological description of the mesopelagic predatory fish, Stomias boa, based on a combined approach of clearing and double staining, serial sections and dissection. In this genus, large pads made of dense connective tissue extend from the first enlarged neural arch to the ventral side of the chordal sheath, embracing the prominent exoccipitals and thus constituting a kind of double ball- and socket joint for the head. The notochordal occipito-vertebral gap is enlarged, probably not by loss of vertebral centra as is proposed for other genera of the stomiid family, e.g., in Astronesthes or Photostomias. We conclude that this "pseudo-craniovertebral articulation" serves as a functional substitute for the absent vertebrae and strengthens the flexible, anterior part of the vertebral column during extreme dorsal expansion of the gape during prey capture and swallowing.

A avaliação da adequação às boas práticas ocorreu por meio da aplicação da lista de verificação com base na Portaria 78/09-RS. A avaliação da higiene das superfícies, por meio da técnica de Trifosfato de Adenosina bioluminescência, apontou que 13 entre as 39 superfícies analisadas foram classificadas como insatisfatórias. Todas as UANs apresentaram menos de 50% de conformidade frente à lista de verificação. Destacam-se os itens Higienização, Preparação do alimento, Armazenagem e transporte do alimento preparado, como os itens com maiores percentuais de não-conformidades. Os itens Abastecimento de água e Controle de pragas foram 100% conformes em todas as UANs. Os resultados demonstram que é imprescindível que estas UANs revejam os procedimentos de higiene e executem de forma efetiva as boas prá- ticas nas rotinas de produção e distribuição de alimentos.

Sarcocystis nesbitti, using snakes as the definitive host, is a causative agent of acute human muscular sarcocystosis in Malaysia. Therefore, it is important to explore the distribution and prevalence of S. nesbitti in snakes. Nevertheless, epizootiological information of S. nesbitti in snakes remains insufficient because few surveys have assessed Sarcocystis infection in snakes in endemic countries. In Japan, snakes are popular exotic pet animals that are imported from overseas, but the degree of Sarcocystis infection in them remains unclear. The possibility exists that muscular sarcocystosis by S. nesbitti occurs in contact with captive snakes in non-endemic countries. For a total of 125 snake faecal samples from 67 snake species collected at animal hospitals, pet shops and a zoo, this study investigated the presence of Sarcocystis using polymerase chain reaction (PCR) for the 18S ribosomal RNA gene (18S rDNA). Four (3.2%) faecal samples were positive by PCR. Phylogenetic analysis of the 18S rDNA sequences obtained from four amplification products revealed one isolate from a beauty snake (Elaphe taeniura), Sarcocystis zuoi, which uses rat snakes as the definitive host. The isolate from a Macklot's python (Liasis mackloti) was closely related with unidentified Sarcocystis sp. from reticulated pythons in Malaysia. The remaining two isolates from tree boas (Corallus spp.) were closely related with Sarcocystis lacertae, Sarcocystis gallotiae and unidentified Sarcocystis sp. from smooth snakes, Tenerife lizards and European shrews, respectively. This report is the first of a study examining the distribution of Sarcocystis species in captive snakes in Japan.

O simbolismo religioso, expresso em rituais de fé e de submissão, permeado por um catolicismo popular, articula-se às demandas de dominação política e econômica, típicas das práticas de mandonismo e de coronelismo brasileiro. Tal simbolismo, ainda, constrói uma economia de trocas simbólicas das quais surgem sofisticadas estratégias de dominação, resistência e negociação entre religiosos, coronéis e sertanejos. A realidade em Boa Vista entre as décadas de 1840 e 1860 foi um jogo em que política e religiosidade constituíram campos de poder nos quis as fronteiras do sagrado e do profano constituíam a arena privilegiada de atuação de Frei Francisco de Monte São Vitor.

2013-05-01

As part of the calibration of the second lifetime position on the Cosmic Origins Spectrograph (COS) far-ultraviolet (FUV) detectors, observations of the external target, G191-B2B, were obtained with the G130M, G160M, and G140L gratings in combi- nation with the Bright Object Aperture. The observations were designed to verify the performance of these spectroscopic modes by reproducing similar observations taken during the SM4 Servicing Mission Observatory Verification (SMOV) of COS. These observations allowed for a detailed determination of the spatial location and profile of the spectra from the three gratings, as well as a determination of the spectral resolution of the G130M grating prior to and after the lifetime move. In general, the negligi- ble differences which exist between the two lifetime positions can be attributed to slight differences in the optical path. In particular, the spectral resolution appears to be slightly improved. The stability of the absolute and relative flux calibration was investigated for G130M as well using STIS echelle data of G191-B2B. We determine that the COS ab- solute flux calibration with the BOA is accurate to 10%, and flux calibrated data are reproducible at the 1-2% level since SMOV.

Inclusion body disease (IBD) is an infectious fatal disease of snakes typified by behavioral abnormalities, wasting, and secondary infections. At a histopathological level, the disease is identified by the presence of large eosinophilic cytoplasmic inclusions in multiple tissues. To date, no virus or other pathogen has been definitively characterized or associated with the disease. Using a metagenomic approach to search for candidate etiologic agents in snakes with confirmed IBD, we identified and de novo assembled the complete genomic sequences of two viruses related to arenaviruses, and a third arenavirus-like sequence was discovered by screening an additional set of samples. A continuous boa constrictor cell line was established and used to propagate and isolate one of the viruses in culture. Viral nucleoprotein was localized and concentrated within large cytoplasmic inclusions in infected cells in culture and tissues from diseased snakes. In total, viral RNA was detected in 6/8 confirmed IBD cases and 0/18 controls. These viruses have a typical arenavirus genome organization but are highly divergent, belonging to a lineage separate from that of the Old and New World arenaviruses. Furthermore, these viruses encode envelope glycoproteins that are more similar to those of filoviruses than to those of other arenaviruses. These findings implicate these viruses as candidate etiologic agents of IBD. The presence of arenaviruses outside mammals reveals that these viruses infect an unexpectedly broad range of species and represent a new reservoir of potential human pathogens. Inclusion body disease (IBD) is a common infectious disease of captive snakes. IBD is fatal and can cause the loss of entire animal collections. The cause of the disease has remained elusive, and no treatment exists. In addition to being important to pet owners, veterinarians, breeders, zoological parks, and aquariums, the study of animal disease is significant since animals are the source of

Though international trade is increasing, the significance of imported reptiles as carriers of pathogens with relevance to animal and human health is largely unknown. Reptiles imported to Germany were therefore investigated for blood parasites using light microscopy, and the detected parasites were morphologically characterized. Four hundred ten reptiles belonging to 17 species originating from 11 Asian, South American and African countries were included. Parasites were detected in 117 (29%) of individual reptiles and in 12 species. Haemococcidea (Haemogregarina, Hepatozoon, Schellackia) were found in 84% of snakes (Python regius, Corallus caninus), 20% of lizards (Acanthocercus atricollis, Agama agama, Kinyongia fischeri, Gekko gecko) and 50% of turtles (Pelusios castaneus). Infections with Hematozoea (Plasmodium, Sauroplasma) were detected in 14% of lizards (Acanthocercus atricollis, Agama agama, Agama mwanzae, K. fischeri, Furcifer pardalis, Xenagama batillifera, Acanthosaura capra, Physignathus cocincinus), while those with Kinetoplastea (Trypanosoma) were found in 9% of snakes (Python regius, Corallus caninus) and 25 % of lizards (K. fischeri, Acanthosaura capra, G. gecko). Nematoda including filarial larvae parasitized in 10% of lizards (Agama agama, Agama mwanzae, K. fischeri, Fu. pardalis, Physignathus cocincinus). Light microscopy mostly allowed diagnosis of the parasites' genus, while species identification was not possible because of limited morphological characteristics available for parasitic developmental stages. The investigation revealed a high percentage of imported reptiles being carriers of parasites while possible vectors and pathogenicity are largely unknown so far. The spreading of haemoparasites thus represents an incalculable risk for pet reptiles, native herpetofauna and even human beings.

The guava fruit (Psidium guajava) is among the most strongly affected by fruit flies in Brazil. In the Brazilian Amazon, 11 species of Anastrepha have been reported in guava orchards to date. This work aimed to identify the species of Anastrepha present in a guava orchard in the municipality of Boa Vista, determine the species infesting the fruits, and identify any parasitoids present. Two McPhail traps with food bait were installed and weekly collections were made between January and December 2008. Fruits were also collected systematically during this period, with a view to determining the association between host plant and tephritid species. Nine species of Anastrepha were identified, in addition to one specimen belonging to a probable new species. Anastrepha striata Schiner, Anastrepha sororcula Zucchi, Anastrepha obliqua (Macquart), and Anastrepha fraterculus (Wiedemann) were the dominant species in the orchard, accounting for 84.8% of all captured individuals. All females collected directly from fruits were A. striata. Doryctobracon areolatus (Szépligeti) was the only parasitoid species obtained. In this work, Anastrepha ethalea (Walker) is reported for the first time in the state of Roraima.

Full Text Available A descrição é um dos principais modos de organização do discurso, pois é por intermédio dela que se adquire a base fundamental para bem utilizar outras formas de organizar a redação de um texto. A descrição viabiliza a possibilidade de as pessoas terem a noção particular e individual sobre si mesmas e sobre tudo o que as envolve. Enfatiza-se que a construção das imagens que constituem o mundo em que vivemos ocorre através dos cinco sentidos (visão, audição, olfato, paladar e tato e da imaginação criadora do ser humano. Explicitar todos esses aspectos fomentou a elaboração deste estudo que tem por objetivo demonstrar a importância da descrição como ferramenta fundamental para uma boa comunicação. Para isso, utilizou-se a pesquisa bibliográfica de natureza qualitativa como metodologia neste trabalho que se caracteriza como um estudo exploratório. Do referencial teórico que embasou o trabalho, cabe ressaltar que a descrição é a forma mais natural no ser humano de produzir um texto porque os instrumentos do descrever, ou seja, os sentidos humanos, já estão em nós e constituem os elementos vitais da nossa sensibilidade (AMARAL; ANTÔNIO; PATROCÍNIO, 2001. Neste estudo, por meio da análise de diversos tipos de texto, são identificadas técnicas descritivas e formas de influência exercidas pela descrição nos modos de organização do discurso narrativo e argumentativo. Em síntese, é preciso priorizar o estudo da descrição como modo de organização do discurso essencial para a obtenção de conhecimento de mundo e para a realização de uma comunicação precisa e eficaz.

Full Text Available El análisis sobre el uso del hábitat es una herramienta fundamental para la conservación y el manejo de las poblaciones silvestres. Cuantificar los cambios en el uso de recursos asociados con la reproducción puede ofrecer una idea de las fuerzas selectivas que actúan sobre los organismos durante esta fase crítica de su historia de vida. Se ha observado en distintas especies de ofidios que hembras grávidas frecuentan hábitats distintos de los que utilizan hembras no grávidas y machos, por lo que la selección de un ambiente en particular podría estar influenciado por el comportamiento reproductivo. En el presente trabajo evaluamos el uso del hábitat en Boa constrictor occidentalis mediante radiorastreo a nivel de microhábitat durante la estación seca en la localidad de El Quemado, Departamento Pocho, Córdoba. Se marcaron mediante radiotransmisores 14 individuos adultos: 5 hembras reproductivas, 4 hembras no reproductivas y 5 machos reproductivos. Las diferencias en el uso del hábitat observadas en las lampalaguas en función de la condición reproductiva durante la estación seca, reflejarían diferencias en los requerimientos para la termorregulación. El uso que las hembras reproductivas hacen del hábitat les permitiría seleccionar sitios que brinden buenos lugares para asolearse permitiendo obtener temperaturas mayores y óptimas para el desarrollo de los embriones. Habitat use analysis is a basic tool for the conservation and management of wild populations. Quantifying the changes in the use of resources associated with reproduction can offer an insight into the selective forces acting on organisms in this critical phase of life history. Reproduction condition often has obvious effects on habitat use. Reproductive individual females have been observed in habitats different from those frequented by males and non reproductive females. In this study, we evaluate the differential use of habitats in Boa constrictor occidentalis

Full Text Available RESUMO: Doença do corpúsculo de inclusão (IBD é uma enfermidade caracterizada por corpúsculos intracitoplasmáticos em diversos tecidos, principalmente no sistema nervoso central, responsável pelos principais sinais clínicos atribuídos à doença que acomete Boas e Phytons de cativeiro; essa enfermidade tem sido uma preocupação mundial devido à alta morbidade e mortalidade. O diagnóstico é feito pela visualização dos corpúsculos causados por um Arenavírus modificado. Salmonella sp. pertence à microflora de animais de sangue frio e quente, e é um patógeno oportunista que pode causar quadros gastrointestinais ou septicêmicos. Em répteis a Salmonella sp. é a bactéria com maior frequência de citações em espondilites e osteomielites. Relata-se um caso de uma jiboia (Boa constrictor constrictor que apresentava restrição de movimento e múltiplos granulomas dorsais nas vértebras; à radiografia evidenciaram-se regiões fraturadas. Após meses de tratamentos sem melhora clínica e o aparecimento de novas lesões o animal ficou prostrado, anoréxico, caquético e desenvolveu opistótono; optou-se pela eutanásia. À necropsia verificaram-se, nas vértebras, múltiplos focos dorsais com aumento de volume que variava de 1,7cm à 3,8cm. Ao corte as vértebras eram deformadas e exibiam conteúdo caseoso focal próximo ao canal medular, este foi coletado para microbiologia onde se identificou Salmonella sp. À microscopia as vértebras tinham um infiltrado inflamatório multifocal moderado de macrófagos e heterofilos. Algumas áreas possuíam grande quantidade de granulomas com calcificação central e inúmeras células gigantes; outros mostravam áreas de osteomalácia e fibrose. Em raros focos havia fratura do corpo vertebral e compressão da medula espinhal com leve infiltrado inflamatório invadindo o canal medular. No pulmão, principalmente no epitélio brônquico, por vezes até dentro de linfócitos do tecido linfoide

The Fdb3 transcription factor of the Fusarium Detoxification of Benzoxazolinone gene cluster is required for MBOA but not BOA degradation in Fusarium pseudograminearum.

Science.gov (United States)

Kettle, Andrew J; Carere, Jason; Batley, Jacqueline; Manners, John M; Kazan, Kemal; Gardiner, Donald M

2016-03-01

A number of cereals produce the benzoxazolinone class of phytoalexins. Fusarium species pathogenic towards these hosts can typically degrade these compounds via an aminophenol intermediate, and the ability to do so is encoded by a group of genes found in the Fusarium Detoxification of Benzoxazolinone (FDB) cluster. A zinc finger transcription factor encoded by one of the FDB cluster genes (FDB3) has been proposed to regulate the expression of other genes in the cluster and hence is potentially involved in benzoxazolinone degradation. Herein we show that Fdb3 is essential for the ability of Fusarium pseudograminearum to efficiently detoxify the predominant wheat benzoxazolinone, 6-methoxy-benzoxazolin-2-one (MBOA), but not benzoxazoline-2-one (BOA). Furthermore, additional genes thought to be part of the FDB gene cluster, based upon transcriptional response to benzoxazolinones, are regulated by Fdb3. However, deletion mutants for these latter genes remain capable of benzoxazolinone degradation, suggesting that they are not essential for this process. Crown Copyright © 2016.

Seasonal influence on biochemical profile and serum protein electrophoresis for Boa constrictor amarali in captivity

Directory of Open Access Journals (Sweden)

LFN Silva

Full Text Available Similarly to other reptiles, snakes are ectothermic animals and depend exclusively on the environment for the maintenance of their physiological, biochemical and immunological processes. Thus, changes in biochemical values can be expected due to seasonal influence. Twenty-two adult specimens of Boa constrictor amarali kept in captivity were used. Blood collections were done in two different seasons: winter (July 2004 and summer (January 2005 for the following assays: uric acid, aspartate aminotransferase (AST, glucose, cholesterol, total protein, and serum protein electrophoresis. The mean biochemical results found in summer and winter, respectively, were: 6.3 ± 3.4 and 11.3 ± 6.2 mg/dL for uric acid; 28.7 ± 12.4 and 20.7 ± 16.2 UI/L for AST; 26.3 ± 17 and 17.4 ± 6.8 mg/dL for glucose; 67.3 ± 30.2 and 69.7 ± 38.5 mg/dL for cholesterol; and 5.9 ± 1.6 and 5.9 ± 1.4 g/dL for total protein. Results regarding electrophoresis in summer and winter, respectively, were: 1.9 ± 0.7 and 2.4 ± 0.6 g/dL for albumin; 0.7 ± 0.2 and 0.5 ± 0.2 g/dL for α-globulin; 1.5 ± 0.5 and 1.7 ± 0.6 g/dL for β-globulin; and 1.8 ± 0.5 and 1.5 ± 0.5 g/dL for g-globulin. In the summer, there was a significant increase in AST and a decrease in uric acid (p < 0.05. Serum protein electrophoresis showed a significant increase in α-globulin fraction (p < 0.05 in the same season. There were not significant differences between seasons for the remaining variables. Based on these results, the period of the year must be considered in the interpretation of some biochemical values for these animals.

Sex allocation and secondary sex ratio in Cuban boa ( Chilabothrus angulifer): mother's body size affects the ratio between sons and daughters

Science.gov (United States)

Frynta, Daniel; Vejvodová, Tereza; Šimková, Olga

2016-06-01

Secondary sex ratios of animals with genetically determined sex may considerably deviate from equality. These deviations may be attributed to several proximate and ultimate factors. Sex ratio theory explains some of them as strategic decisions of mothers improving their fitness by selective investment in sons or daughters, e.g. local resource competition hypothesis (LRC) suggests that philopatric females tend to produce litters with male-biased sex ratios to avoid future competition with their daughters. Until now, only little attention has been paid to examine predictions of sex ratio theory in snakes possessing genetic sex determination and exhibiting large variance in allocation of maternal investment. Cuban boa is an endemic viviparous snake producing large-bodied newborns (˜200 g). Extremely high maternal investment in each offspring increases importance of sex allocation. In a captive colony, we collected breeding records of 42 mothers, 62 litters and 306 newborns and examined secondary sex ratios (SR) and sexual size dimorphism (SSD) of newborns. None of the examined morphometric traits of neonates appeared sexually dimorphic. The sex ratio was slightly male biased (174 males versus 132 females) and litter sex ratio significantly decreased with female snout-vent length. We interpret this relationship as an additional support for LRC as competition between mothers and daughters increases with similarity of body sizes between competing snakes.

Polymethyl-methacrylate (PMMA) is commonly used primarily for baseplates of orthodontic appliances (BOA). The activities of cariogenic bacteria in biofilm on these surfaces may contribute to dental caries, gingival inflammation and periodontal disease. The PMMA incorporated with nanoparticles of silver (NanoAg-I-PMMA) and NanoAg in situ in PMMA (NanoAg-IS-PMMA) have been shown to control the growth of cariogenic bacteria, but clinical trial of anti-cariogenic application of these novel materials in orthodontics has not been evaluated. The main aim of the study is to compare the clinical effectiveness of using NanoAg-IS-PMMA and NanoAg-I-PMMA for construction of new BOA in inhibiting the planktonic growth and biofilm formation of the cariogenic bacteria. Twenty four patients with a median age of 12.6 years (7-15) harboring Streptococcus mutans, Streptococcus sobrinus and Lactobacillus acidophilus as well as Lactobacillus casei participated in the randomized, double-blind, cross-over study. The experimental BOA, NanoAg-IS-BOA and NanoAg-I-BOA, contained 0.5% w/w NanoAg while the control BOA was standard PMMA. Antibacterial effect of NanoAg-IS-BOA and NanoAg-I-BOA was assessed against test cariogenic bacteria by planktonic and biofilm bacterial cells growth inhibition. The average levels of test cariogenic bacteria in saliva decreased about 2 to 70 fold (30.9-98.4%) compared to baseline depending on the microorganism type and test BOA. Biofilm inhibition analysis demonstrated that NanoAg-I-BOA and NanoAg-IS-BOA inhibited the biofilm of all test bacteria by 20.1 to 79.9% compared to BOA. NanoAg-IS-BOA had a strong anti-biofilm effect against S. mutans, S. sobrinus and L. casei. However, NanoAg-I-BOA showed only slight anti-biofilm effects on test bacteria. Most notably, at all period of the clinical trial, NanoAg-IS-BOA showed a higher antibacterial activity than NanoAg-I-BOA. Based on the novel data that presented here, the NanoAg-IS-BOA had strong antimicrobial

Assessment was done subjectively and densitometry was performed using a defined protocol. The length of the right lung was calculated to be 11.1% of the body length, without a significant difference between species. The length of the left lung in proportion to the right was dependent on the species examined. The most developed left lung was in P. regius (81.2%), whereas in B. constrictor, the left lung was vestigial or absent (24.7%). A median attenuation of -814.6 HU and a variability of 45.9 HU were calculated for all species with no significant difference between species. Within the species, a significantly higher attenuation was found for P. regius in the dorsal and cranial aspect of the lung compared with the ventral and caudal part. In B. constrictor, the reduced left lung was significantly hyperattenuating compared with the right lung. Results of this study emphasize the value of CT and provide basic reference data for assessment of the snake lung in these species. Veterinary Radiology &

Brachycephalic obstructive airway syndrome (BOAS) is an important health and welfare problem in several popular dog breeds. Whole-body barometric plethysmography (WBBP) is a non-invasive method that allows safe and repeated quantitative measurements of respiratory cycles on unsedated dogs. Here respiratory flow traces in French bulldogs from the pet population were characterised using WBBP, and a computational application was developed to recognise affected animals. Eighty-nine French bulldogs and twenty non-brachycephalic controls underwent WBBP testing. A respiratory functional grading system was used on each dog based on respiratory signs (i.e. respiratory noise, effort, etc.) before and after exercise. For development of an objective BOAS classifier, functional Grades 0 and I were considered to have insignificant clinical signs (termed here BOAS-) and Grades II and III to have significant signs (termed here BOAS+). A comparison between owner-perception of BOAS and functional grading revealed that 60 % of owners failed to recognise BOAS in dogs that graded BOAS+ in this study.WBBP flow traces were found to be significantly different between non-brachycephalic controls and Grade 0 French bulldogs; BOAS- and BOAS+ French bulldogs. A classifier was developed using quadratic discriminant analysis of the respiratory parameters to distinguish BOAS- and BOAS + French bulldogs, and a BOAS Index was calculated for each dog. A cut-off value of the BOAS Index was selected based on a receiver operating characteristic (ROC) curve. Sensitivity, specificity, positive predictive value, and negative predictive value of the classifier on the training group (n=69) were 0.97, 0.93, 0.95, and 0.97, respectively. The classifier was validated using a test group of French bulldogs (n=20) with an accuracy of 0.95. WBBP offers objective screening for the diagnosis of BOAS in French Bulldogs. The technique may be applied to other brachycephalic breeds affected by BOAS, and possibly to

Full Text Available The objective of this study was to diagnose pests, diseases, weeds, and practices associated with the use of agrochemicals on the production of vegetables under protected conditions in Boa Vista, Roraima, Brazil. The descriptive study was conducted in urban and rural areas during February to April 2008, in the gardens monitored by Project Greenhouse, administered by the Municipal Development agricultural Secretary of the City. The data collection instrument was a semistructured questionnaire with 50 questions, applied in situ without notice to 75 farmers (47% of the population under study.Data were analyzed by descriptive statistics. After analyzing the data it was found that the whitefly, aphids, thrips and caterpillars were the insect pests that needed to be better controlled. The principal diseases were blight and leaf blight. Significant weed pests originated from the species of the families Poaceae, Cyperaceae, Amaranthaceae, and Portulacaeae. Relative to the use of pesticides, the results showed that 68% of farmers used insecticides, 24% fungicides, and 8% herbicides; 92% indicated that they had received some kind of technical guidance and 41.3% seek the technical assistance in order to acquire a pesticide. Therefore, we conclude that there is a high incidence of problems in plant vegetable gardens, intensive use of pesticides, a variety of formulations of insecticides, fungicides and herbicides associated with the adoption of practices and attitudes of risk for farmers, which can aggravate the direct and indirect problems of intoxication, and cause contamination to the environment. =Objetivou-se com esse trabalho fazer o diagnóstico das pragas, doenças, plantas daninhas e das práticas associadas ao uso dos agrotóxicos utilizados na produção de hortaliças, em ambiente protegido, no município de Boa Vista, Roraima.

Full Text Available Esta pesquisa se propôs a problematizar, através dos Estudos de Gênero e Culturais Pós-Estruturalistas, as relações entre professoras e mães de alunos na Educação Infantil. Entende-se que os discursos da pedagogia, da medicina e da psicologia do desenvolvimento, que fundamentam a formação docente, instituem não só posições de sujeito e identidades de professor/a e aluno/a mas, também, determinadas formas de exercício da maternidade. A partir da análise cultural se problematizam alguns ensinamentos sobre maternidade que tanto são produzidos nas relações escolares, como ao mesmo tempo são configurados. Foi observada uma turma de Educação Infantil, atentando para as práticas discursivas que permeiam as relações entre mães e professora, materializadas através dos bilhetes de agenda e dos contatos na entrada e saída da aula, bem como aquelas que delimitam e atravessam as práticas pedagógicas desenvolvidas, sobretudo na semana do dia das mães. Apesar da ênfase atualmente atribuída à participação da família-mãe na escola, estas são chamadas apenas em momentos definidos e delimitados pela escola e pela professora. De fato, a participação da instituição escolar na valoração e legitimação de determinadas formas de exercício da maternidade é bastante intensa, pois a representação de boa-mãe é definida em sutis falas do cotidiano escolar, onde cenas familiares são suscitadas. Entendendo que essas relações têm efeitos pedagógicos importantes pode se observar que, por um lado elas educam as mães das crianças para exercerem uma maternidade definida como aceitável pela instituição, ao mesmo tempo em que ensinam às crianças como suas mães devem ser.

Xiaoming Zhang

2013-02-01

Full Text Available Inspired by the transmission of beans in nature, a novel evolutionary algorithm-Bean Optimization Algorithm (BOA is proposed in this paper. BOA is mainly based on the normal distribution which is an important continuous probability distribution of quantitative phenomena. Through simulating the self-adaptive phenomena of plant, BOA is designed for solving continuous optimization problems. We also analyze the global convergence of BOA by using the Solis and Wetsarsquo; research results. The conclusion is that BOA can converge to the global optimization solution with probability one. In order to validate its effectiveness, BOA is tested against benchmark functions. And its performance is also compared with that of particle swarm optimization (PSO algorithm. The experimental results show that BOA has competitive performance to PSO in terms of accuracy and convergence speed on the explored tests and stands out as a promising alternative to existing optimization methods for engineering designs or applications.

Full Text Available Abstract Background Burkholderia pseudomallei and Burkholderia mallei cause the diseases melioidosis and glanders, respectively. A well-studied aspect of pathogenesis by these closely-related bacteria is their ability to invade and multiply within eukaryotic cells. In contrast, the means by which B. pseudomallei and B. mallei adhere to cells are poorly defined. The purpose of this study was to identify adherence factors expressed by these organisms. Results Comparative sequence analyses identified a gene product in the published genome of B. mallei strain ATCC23344 (locus # BMAA0649 that resembles the well-characterized Yersinia enterocolitica autotransporter adhesin YadA. The gene encoding this B. mallei protein, designated boaA, was expressed in Escherichia coli and shown to significantly increase adherence to human epithelial cell lines, specifically HEp2 (laryngeal cells and A549 (type II pneumocytes, as well as to cultures of normal human bronchial epithelium (NHBE. Consistent with these findings, disruption of the boaA gene in B. mallei ATCC23344 reduced adherence to all three cell types by ~50%. The genomes of the B. pseudomallei strains K96243 and DD503 were also found to contain boaA and inactivation of the gene in DD503 considerably decreased binding to monolayers of HEp2 and A549 cells and to NHBE cultures. A second YadA-like gene product highly similar to BoaA (65% identity was identified in the published genomic sequence of B. pseudomallei strain K96243 (locus # BPSL1705. The gene specifying this protein, termed boaB, appears to be B. pseudomallei-specific. Quantitative attachment assays demonstrated that recombinant E. coli expressing BoaB displayed greater binding to A549 pneumocytes, HEp2 cells and NHBE cultures. Moreover, a boaB mutant of B. pseudomallei DD503 showed decreased adherence to these respiratory cells. Additionally, a B. pseudomallei strain lacking expression of both boaA and boaB was impaired in its ability to

This paper presents a new distributed Bayesian optimization algorithm (BOA) to overcome the efficiency problem when solving NP scheduling problems.The proposed approach integrates BOA into the co-evolutionary schema,which builds up a concurrent computing environment.A new search strategy is also introduced for local optimization process.It integrates the reinforcement learning(RL) mechanism into the BOA search processes,and then uses the mixed probability information from BOA (post-probability) and RL (pre-probability) to enhance the cooperation between different local controllers,which improves the optimization ability of the algorithm.The experiment shows that the new algorithm does better in both optimization (2.2%) and convergence (11.7%),compared with classic BOA.

Giant Constrictors' Climate Space The giant constrictors' climate space data set represents the information needed to recreate the climate space and climate matching analyses in Reed and Rodda (2009). A detailed methodology and results are included in that report. The data include locations for nine species of large constrictors including Python molurus, Broghammerus reticulatus, P. sebae, P. natalensis, Boa constrictor, Eunectes notaeus, E. deschauenseei, E. beniensis, and E. murinus. The locations are from published sources. Climate data are included for monthly precipitation and average monthly temperature along with the species locations. The individual spreadsheets of location data match the figures in the Reed and Rodda (2009) report, illustrating areas of the mainland United States that match the climate envelope of the native range. The precipitation and temperature data at each location were used to determine the climate space for each species. Graphs of climate space formed the basis for the algorithms in the data set, and more details can be found in Reed and Rodda (2009). These algorithms were used in ArcGIS to generate maps of areas in the United States that matched the climate space of locations of the snakes in their native range. We discovered a rounding error in ArcGIS in the implementation of the algorithms, which has been corrected here. Therefore the shapefiles are slightly different than those appearing in the risk assessment figures illustrating areas of the United States that match the climate envelope of the species in their native ranges. However, the suitable localities are not different at the scale of intended use for these maps, although there are more noticeable differences between areas classified as 'too cold' and 'too hot'.

The major detoxification product in maize roots after 24 h benzoxazolin-2(3H)-one (BOA) exposure was identified as glucoside carbamate resulting from rearrangement of BOA-N-glucoside, but the pathway of N-glucosylation, enzymes involved and the site of synthesis were previously unknown. Assaying whole cell proteins revealed the necessity of H2O2 and Fe(2+) ions for glucoside carbamate production. Peroxidase produced BOA radicals are apparently formed within the extraplastic space of the young maize root. Radicals seem to be the preferred substrate for N-glucosylation, either by direct reaction with glucose or, more likely, the N-glucoside is released by glucanase/glucosidase catalyzed hydrolysis from cell wall components harboring fixed BOA. The processes are accompanied by alterations of cell wall polymers. Glucoside carbamate accumulation could be suppressed by the oxireductase inhibitor 2-bromo-4´-nitroacetophenone and by peroxidase inhibitor 2,3-butanedione. Alternatively, activated BOA molecules with an open heterocycle may be produced by microorganisms (e.g., endophyte Fusarium verticillioides) and channeled for enzymatic N-glucosylation. Experiments with transgenic Arabidopsis lines indicate a role of maize glucosyltransferase BX9 in BOA-N-glycosylation. Western blots with BX9 antibody demonstrate the presence of BX9 in the extraplastic space. Proteomic analyses verified a high BOA responsiveness of multiple peroxidases in the apoplast/cell wall. BOA incubations led to shifting, altered abundances and identities of the apoplast and cell wall located peroxidases, glucanases, glucosidases and glutathione transferases (GSTs). GSTs could function as glucoside carbamate transporters. The highly complex, compartment spanning and redox-regulated glucoside carbamate pathway seems to be mainly realized in Poaceae. In maize, carbamate production is independent from benzoxazinone synthesis.

Full Text Available As padarias ou panifi cadoras se difundiram no Brasil a partir da colonização, quando portugueses e espanhóis trouxeram hábitos alimentares da Europa, tornando-se parte da nossa história e cultura. Hoje as padarias estão deixando de ser apenas estabelecimentos responsá- veis pela fabricação artesanal e venda de pães, e estão se transformando em centros de convivência, gastronomia e serviços. Com o crescimento populacional em algumas cidades, as pessoas buscam sempre formas mais práticas para se alimentar e também com menor custo, ocasionando vários problemas de intoxicação e infecção alimentar devido a alimentos preparados. Assim, o presente trabalho teve por objetivo avaliar as condições higiênico-sanitárias de três panifi cadoras a partir da aplicação de uma lista de verifi cação e análise microbiológica das superfícies dos equipamentos. Pelos itens avaliados, a panifi cadora B foi a que mais apresentou conformidade aos itens analisados (91,7%, seguida pela panifi cadora A (86,7% e por último a panifi cadora C (83,3%. Concluiu-se que as panifi cadoras encontravam-se em condições higiênico-sanitárias inadequadas. Desta forma foi elaborado um material informativo para incentivar a adoção de medidas corretivas para higiene dos manipuladores e melhor higienização/sanitização dos equipamentos. O comprometimento de todos os envolvidos na produção de panifi cados é uma condição básica para o sucesso da implantação das boas práticas de fabricação e higienização no local de trabalho.

Habitat fragmentation reduces the extent and connectivity of suitable habitats, and can lead to changes in population genetic structure. Limited gene flow among isolated demes can result in increased genetic divergence among populations, and decreased genetic diversity within demes. We assessed patterns of genetic variation in the Caribbean boa Chilabothrus monensis (Epicrates monensis) using two mitochondrial and seven nuclear markers, and relying on the largest number of specimens of these snakes examined to date. Two disjunct subspecies of C. monensis are recognized: the threatened C. m. monensis, endemic to Mona Island, and the rare and endangered C. m. granti, which occurs on various islands of the Puerto Rican Bank. Mitochondrial and nuclear markers revealed unambiguous genetic differences between the taxa, and coalescent species delimitation methods indicated that these snakes likely are different evolutionary lineages, which we recognize at the species level, C. monensis and C. granti. All examined loci in C. monensis (sensu stricto) are monomorphic, which may indicate a recent bottleneck event. Each population of C. granti exclusively contains private mtDNA haplotypes, but five of the seven nuclear genes assayed are monomorphic, and nucleotide diversity is low in the two remaining markers. The faster pace of evolution of mtDNA possibly reflects the present-day isolation of populations of C. granti, whereas the slower substitution rate of nuDNA may instead mirror the relatively recent episodes of connectivity among the populations facilitated by the lower sea level during the Pleistocene. The small degree of overall genetic variation in C. granti suggests that demes of this snake could be managed as a single unit, a practice that would significantly increase their effective population size.

Provocações e novos desafios surgem a cada dia em busca de analisarmos se estamos atuando ou não de forma moral e ética. A sustentabilidade e o consumismo são características bem opostas, de um lado empresas que primam pelo progresso, oferecem vagas de empregos e beneficiam seres humanos com suas atividades, do outro, uma nova educação, dotada de preocupações com a preservação ambiental. Considerado um dos assuntos mais comentados na atualidade, a educação para sustentabilidade está intrinsecamente ligada à solidariedade, respeito e afetividade e precisa estar conectada a três pilares: prosperidade econômica, respeito ao meio ambiente e proteção social. Para isto, é necessário que as pessoas substituam o pensamento capitalista consumista, mantendo a sustentabilidade. Esta pesquisa teve o objetivo de identificar acontecimentos atuais provocados por uma mineradora no município de São João da Boa Vista e o quanto a conscientização pela Educação para a Sustentabilidade pode proporcionar para a localidade e humanidade. Investigouse a Lei Orgânica e Legislação Municipal a fim de evitarem a ação da mineradora e manter, sem maiores danos, o turismo local e regional.   Education is considered an important source of transformation of social being.

This paper describes the design and the capabilities of the Naval Research Laboratory Big Optical Array (BOA), an interferometric optical array for high-resolution imaging of stars, stellar systems, and other celestial objects. There are four important differences between the BOA design and the design of Mark III Optical Interferometer on Mount Wilson (California). These include a long passive delay line which will be used in BOA to do most of the delay compensation, so that the fast delay line will have a very short travel; the beam combination in BOA will be done in triplets, to allow measurement of closure phase; the same light will be used for both star and fringe tracking; and the fringe tracker will use several wavelength channels

The plant growth promoter activity of irradiated chitosan on Gladiolus hortulanus cv. Amsterdam was studied. Chitosan was applied in the form of foliar spray at third leaf stage. Corms were sown at three different dates with 15-day intervals. Data on several parameters such as survival percentage, leaf area, plant height, number of florets per spike, and vase life were collected. Chitosan-treated plants showed superior results as compared to the control samples. Acrylic acid-based superabsorbent hydrogel was prepared using phenyltriethoxysilane (PTES) as cross-linker. Different amounts of PTES were incorporated and irradiated at different doses of up to a maximum of 30 kGy. The cross-linked acrylic acid showed hydrogel properties, and its swelling kinetics, gel fraction, and equilibrium degree of swelling (EDS) were studied. The swelling of hydrogel was also affected by pH, ionic strength, and temperature. These hydrogels can be further explored as a super water absorbent material in semi-arid and drought prone areas.

Impact of Facial Conformation on Canine Health: Brachycephalic Obstructive Airway Syndrome

2015-01-01

The domestic dog may be the most morphologically diverse terrestrial mammalian species known to man; pedigree dogs are artificially selected for extreme aesthetics dictated by formal Breed Standards, and breed-related disorders linked to conformation are ubiquitous and diverse. Brachycephaly–foreshortening of the facial skeleton–is a discrete mutation that has been selected for in many popular dog breeds e.g. the Bulldog, Pug, and French Bulldog. A chronic, debilitating respiratory syndrome, whereby soft tissue blocks the airways, predominantly affects dogs with this conformation, and thus is labelled Brachycephalic Obstructive Airway Syndrome (BOAS). Despite the name of the syndrome, scientific evidence quantitatively linking brachycephaly with BOAS is lacking, but it could aid efforts to select for healthier conformations. Here we show, in (1) an exploratory study of 700 dogs of diverse breeds and conformations, and (2) a confirmatory study of 154 brachycephalic dogs, that BOAS risk increases sharply in a non-linear manner as relative muzzle length shortens. BOAS only occurred in dogs whose muzzles comprised less than half their cranial lengths. Thicker neck girths also increased BOAS risk in both populations: a risk factor for human sleep apnoea and not previously realised in dogs; and obesity was found to further increase BOAS risk. This study provides evidence that breeding for brachycephaly leads to an increased risk of BOAS in dogs, with risk increasing as the morphology becomes more exaggerated. As such, dog breeders and buyers should be aware of this risk when selecting dogs, and breeding organisations should actively discourage exaggeration of this high-risk conformation in breed standards and the show ring.

Full Text Available Specimens of Hepatozoon-infected Boa constrictor constrictor were obtained from localities in Pará State, north Brazil. Gametocytes in erythrocytes of the peripheral blood measured 10 x 2.5-16.2 x 3.7 µm. They were similar to those described as Haemogregarina terzii by Sambon & Seligmann (1907 in B. c. constrictor, in that they did not distort the infected erythrocyte, and their dimensions approximated those given by Carini (1947. Lungs and liver of infected snakes contained actively dividing meronts of a single type, and cysts containing two to six cystozoites were also present in the liver. Our initial feeding of Culex quinquefasciatus on infected snakes consistently resulted in a heavy death-rate of the engorged mosquitoes, with only a few surviving till the 9th day post feeding. These contained numerous oocysts which were undivided or in early stages of division. A fifth and final experiment, however, provided a few mosquitoes surviving up to 21 days post infection (dpi, and these contained fully sporulated oocysts measuring 190-200 µm in diameter and containing over 60 sporocysts of 19-30 µm in diameter. The number of sporozoites in each sporocyst was estimated as approximately 50. The nature of the parasite's sporogonic cycle in the mosquito thus justifies inclusion of this haemogregarine in the genus Hepatozoon. Two wild-caught specimens of the lizard Tropidurus torquatus were fed with mosquitoes containing fully developed oocysts (21 dpi. When sacrificed, three months later, large numbers of dizoic, tetrazoic and hexazoic cysts were demonstrated in their livers. Cystozoites released from these cysts were shown to possess a conspicuous refractile body.

Distinguishing the Effects of Bond-Length Alternation versus Bond-Order Alternation on the Nonlinear Optical Properties of π-Conjugated Chromophores

Gieseking, Rebecca L.; Risko, Chad; Bredas, Jean-Luc

2015-01-01

Understanding the relationships between the molecular nonlinear optical (NLO) properties and the bond-length alternation (BLA) or π-bond-order alternation (BOA) along the molecular backbone of linear π-conjugated systems has proven widely useful in the development of NLO organic chromophores and materials. Here, we examine model polymethines to elucidate the reliability of these relationships. While BLA is solely a measure of molecular geometric structure, BOA includes information pertaining to the electronic structure. As a result, BLA is found to be a good predictor of NLO properties only when optimized geometries are considered, whereas BOA is more broadly applicable. Proper understanding of the distinction between BLA and BOA is critical when designing computational studies of NLO properties, especially for molecules in complex environments or in nonequilibrium geometries. © 2015 American Chemical Society.

Proper understanding of the distinction between BLA and BOA is critical when designing computational studies of NLO properties, especially for molecules in complex environments or in nonequilibrium geometries. © 2015 American Chemical Society.

Full Text Available The purpose of this work was to describe the population patterns of Anastrepha in three municipalities of the state of Roraima, Brazil, via faunistic analysis. Weekly collections were performed from January through December 2008, using McPhail traps containing 5% hydrolysed protein, in domestic orchards in the municipalities of Boa Vista, Bonfim and Pacaraima. We captured 301 females of Anastrepha in Boa Vista, 212 in Bonfim, and 167 in Pacaraima. Boa Vista presented the highest species richness (S = 10 and Pacaraima the lowest (S = 4. Anastrepha striata was the predominant species in Boa Vista (47.18% and Pacaraima (65.87%, whereas A. obliqua predominated in Bonfim (46.23%. Boa Vista presented the highest Shannon-Wiener diversity index (H' = 1.19 and Margalef index (α = 1.58, and Bonfim presented the highest Pielou's evenness index (J' = 0.69. In Pacaraima the cumulative curves reached stability, confirming that the observed and expected species richness were the same. In the other two municipalities, the curves showed a moderate growth, suggesting that the sampling effort was not sufficient to produce an accurate depiction of species richness. In this study, Anastrepha zernyi is reported for the first time in Roraima.

2011-01-01

Breakout afterburner (BOA) laser-ion acceleration has been demonstrated for the first time in the laboratory. In the BOA, an initially solid-density target undergoes relativistically induced transparency, initiating a period of enhanced ion acceleration. First-ever kinetic simulations of the BOA in three dimensions show that the ion beam forms lobes in the direction orthogonal to laser polarization and propagation. Analytic theory presented for the electron dynamics in the laser ponderomotive field explains how azimuthal symmetry breaks even for a symmetric laser intensity profile; these results are consistent with recent experiments at the Trident laser facility.

Does really Born-Oppenheimer approximation break down in charge transfer processes? An exactly solvable model

International Nuclear Information System (INIS)

Kuznetsov, Alexander M.; Medvedev, Igor G.

2006-01-01

Effects of deviation from the Born-Oppenheimer approximation (BOA) on the non-adiabatic transition probability for the transfer of a quantum particle in condensed media are studied within an exactly solvable model. The particle and the medium are modeled by a set of harmonic oscillators. The dynamic interaction of the particle with a single local mode is treated explicitly without the use of BOA. Two particular situations (symmetric and non-symmetric systems) are considered. It is shown that the difference between the exact solution and the true BOA is negligibly small at realistic parameters of the model. However, the exact results differ considerably from those of the crude Condon approximation (CCA) which is usually considered in the literature as a reference point for BOA (Marcus-Hush-Dogonadze formula). It is shown that the exact rate constant can be smaller (symmetric system) or larger (non-symmetric one) than that obtained in CCA. The non-Condon effects are also studied

Microbes encounter a broad spectrum of antimicrobial compounds in their environments and often possess metabolic strategies to detoxify such xenobiotics. We have previously shown that Fusarium verticillioides, a fungal pathogen of maize known for its production of fumonisin mycotoxins, possesses two unlinked loci, FDB1 and FDB2, necessary for detoxification of antimicrobial compounds produced by maize, including the γ-lactam 2-benzoxazolinone (BOA). In support of these earlier studies, microarray analysis of F. verticillioides exposed to BOA identified the induction of multiple genes at FDB1 and FDB2, indicating the loci consist of gene clusters. One of the FDB1 cluster genes encoded a protein having domain homology to the metallo-β-lactamase (MBL) superfamily. Deletion of this gene (MBL1) rendered F. verticillioides incapable of metabolizing BOA and thus unable to grow on BOA-amended media. Deletion of other FDB1 cluster genes, in particular AMD1 and DLH1, did not affect BOA degradation. Phylogenetic analyses and topology testing of the FDB1 and FDB2 cluster genes suggested two horizontal transfer events among fungi, one being transfer of FDB1 from Fusarium to Colletotrichum, and the second being transfer of the FDB2 cluster from Fusarium to Aspergillus. Together, the results suggest that plant-derived xenobiotics have exerted evolutionary pressure on these fungi, leading to horizontal transfer of genes that enhance fitness or virulence.

Computer-based Creativity Enhanced Conceptual Design Model for Non-routine Design of Mechanical Systems

Computer-based conceptual design for routine design has made great strides, yet non-routine design has not been given due attention, and it is still poorly automated. Considering that the function-behavior-structure(FBS) model is widely used for modeling the conceptual design process, a computer-based creativity enhanced conceptual design model(CECD) for non-routine design of mechanical systems is presented. In the model, the leaf functions in the FBS model are decomposed into and represented with fine-grain basic operation actions(BOA), and the corresponding BOA set in the function domain is then constructed. Choosing building blocks from the database, and expressing their multiple functions with BOAs, the BOA set in the structure domain is formed. Through rule-based dynamic partition of the BOA set in the function domain, many variants of regenerated functional schemes are generated. For enhancing the capability to introduce new design variables into the conceptual design process, and dig out more innovative physical structure schemes, the indirect function-structure matching strategy based on reconstructing the combined structure schemes is adopted. By adjusting the tightness of the partition rules and the granularity of the divided BOA subsets, and making full use of the main function and secondary functions of each basic structure in the process of reconstructing of the physical structures, new design variables and variants are introduced into the physical structure scheme reconstructing process, and a great number of simpler physical structure schemes to accomplish the overall function organically are figured out. The creativity enhanced conceptual design model presented has a dominant capability in introducing new deign variables in function domain and digging out simpler physical structures to accomplish the overall function, therefore it can be utilized to solve non-routine conceptual design problem.

Introduction The aim of this study was to objectively ascertain the level of readability of standardised consent forms for orthopaedic procedures. Methods Standardised consent forms (both in summary and detailed formats) endorsed by the British Orthopaedic Association (BOA) were retrieved from orthoconsent.com and assessed for readability. This involved using an online tool to calculate the validated Flesch reading ease score (FRES). This was compared with the FRES for the National Health Service (NHS) Consent Form 1. Data were analysed and interpreted according to the FRES grading table. Results The FRES for Consent Form 1 was 55.6, relating to the literacy expected of an A level student. The mean FRES for the BOA summary consent forms (n=27) was 63.6 (95% confidence interval [CI]: 61.2-66.0) while for the detailed consent forms (n=32), it was 68.9 (95% CI: 67.7-70.0). All BOA detailed forms scored >60, correlating to the literacy expected of a 13-15-year-old. The detailed forms had a higher FRES than the summary forms (p<0.001). Conclusions This study demonstrates that the BOA endorsed standardised consent forms are much easier to read and understand than the NHS Consent Form 1, with the detailed BOA forms being the easiest to read. Despite this, owing to varying literacy levels, a significant proportion of patients may struggle to give informed consent based on the written information provided to them.

Barnes, J P; Putnam, A R

1987-04-01

Two phytotoxic compounds [2,4-dihydroxy-1,4(2H)-benzoxazin-3-one (DIBOA) and 2(3H)-benzoxazolinone (BOA)] were previously isolated and identified in 35-day-old greenhouse-grown rye shoot tissue. Both compounds were also detected by TLC in greenhouse-grown root and fieldgrown shoot tissue. The concentration of DIBOA varied in the tissues, with the greatest quantity detected in greenhouse-grown shoots. DIBOA and BOA were compared with β-phenyllactic acid (PLA) and β-hydroxybutyric acid (HBA) for activity on seed germination and seedling growth and were consistently more toxic than either compound. Dicot species tested, including lettuce (Lactuca sativa L.), tomato (Lycopersicon esculentum Mill.), and redroot pigweed (Amaranthus retroflexus L.), were 30% more sensitive than the monocots tested. Of the two benzoxazinone compounds, DIBOA was most toxic to seedling growth. DIBOA and BOA reduced chlorophyll production inChlamydomonas rheinhardtii Dangeard, by 50% at 7.5 × 10(-5) M and 1.0 × 10(-3) M, respectively. Both DIBOA and BOA inhibited emergence of barnyardgrass (Echinochloa crusgalli L. Beauv.), cress (Lepidium sativum L.), and lettuce when applied to soil, indicating their potential for allelopathic activity.

A fritura é um método rápido de cocção, em que há transferência de calor do óleo de fritura para o alimento, propiciando características sensoriais únicas de aroma, textura e sabor. Por ser um método bastante conveniente, é amplamente empregado em serviços de alimentação. No entanto, a qualidade dos alimentos fritos depende principalmente do tipo e da qualidade do óleo usado na fritura. Devido à ação da água presente nos alimentos à elevada temperatura de fritura (em torno de 180ºC e ao oxigênio do ar, ocorre uma série de reações químicas, gerando compostos de degradação que nem sempre são benéfi cos à saúde. Por conta disso, o descarte do óleo de fritura deve ser monitorado, através de métodos físico-químicos, tais como ácidos graxos livres e compostos polares. Atualmente, não há legislação no Brasil para avaliar os óleos descartados. Há apenas recomendações de boas práticas de fritura. Este trabalho objetivou, portanto, avaliar o processo de fritura de 13 estabelecimentos comerciais de Campinas/SP, analisar os óleos descartados e recomendar medidas corretivas. Os resultados deste estudo comprovaram que, embora os estabelecimentos careçam de informações sobre o processo de fritura, os óleos e gorduras descartados, em geral, não apresentaram condições abusivas de uso e poderiam ser utilizados por mais tempo. Embora nada se possa afi rmar sobre a qualidade sensorial dos alimentos fritos e aceitação dos consumidores, é de extrema importância o atendimento às boas práticas de frituras por parte dos produtores de alimentos fritos.

The benzoxazolinones benzoxazolin-2(3H)-one (BOA) and 6-methoxybenzoxazolin-2(3H)-one (MBOA) and selected degradation products of these compounds were examined for their in vitro antifungal activity against Cephalosporium gramineum, Gaeumannomyces graminis var. graminis, and Fusarium culmorum. BOA was also applied to the soil-incorporated inoculum of C. gramineum to test its capability of reducing Cephalosporium stripe disease in winter wheat. MBOA reduced the mycelial growth of G. graminis var. tritici, C. gramineum, and F. culmorum by 50% (EC50) at the concentrations of 77, 134, and 271 microg/mL of corn meal agar, respectively, and the corresponding BOA EC50 values for the fungi were 11, 189, and 456 microg/mL. BOA degradation products 2-amino-3H-phenoxazin-3-one (APO), 2-acetylamino-3H-phenoxazin-3-one (AAPO), and o-aminophenol (o-AP) were much more inhibitory to the growth of C. gramineum and G. graminis var. tritici than the parent compounds. APO, AAPO, and o-AP EC50 values were found to be as low as 0.58, 4.57, and 1.4 microg/mL, respectively, for C. gramineum and 0.78, 2.18, and 0.80 microg/mL for G. graminis var. tritici. These compounds applied at the corresponding concentrations did not significantly affect the mycelial growth of F. culmorum. The treatment of C. gramineum inoculum with a 1% water solution of BOA resulted in a significant reduction infection of winter wheat with C. gramineum as compared to the control with the untreated inoculum,but this treatment was not as effective as the application of a commercial fungicide.

Despite their popularity, many brachycephalic breeds are affected by an early-onset, lifelong respiratory disorder, brachycephalic obstructive airway syndrome (BOAS. This disorder arises due to a mismatch in the proportions of the skull and the soft tissues held within the nose and pharynx, resulting in obstruction of the airway during respiration. Increased airway resistance encourages secondary changes such as eversion of the laryngeal saccules and collapse of the larynx. Clinical signs of BOAS are often early onset and chronic, including dyspnea, exercise intolerance, heat intolerance, and abnormal and increased respiratory noise. Episodes of severe dyspnea can also occur, leading to cyanosis, syncope, and death. BOAS may have a severe impact upon the welfare of affected dogs, compromising their ability to exercise, play, eat, and sleep. Although a well-described condition, with surgical treatments for the palliation of this disorder published since the 1920s, many dogs still experience airway restrictions postsurgically and a compromised quality of life. In addition, the prevalence of this disorder does not appear to have substantially reduced in this time, and may have increased. Ultimately, strategies to improve the breeding of these dogs to prevent BOAS are required to improve brachycephalic health and welfare. Recent studies have revealed conformational risk factors associated with BOAS, such as short muzzles and thick necks, which should be discouraged to avoid perpetuating this serious disorder.

Inclusion body disease (IBD) is a worldwide disease in captive boa constrictors (boa constrictor) and occasionally in other snakes of the families Boidae and Pythonidae. The exact causative agent(s) and pathogenesis are not yet fully understood. Currently, diagnosis of IBD is based on the light microscopic identification of eosinophilic intracytoplasmic inclusion bodies in hematoxylin and eosin stained tissues or blood smears. An antigenically unique 68 KDa protein was identified within the IBD inclusion bodies, called IBD protein. A validated immuno-based ante-mortem diagnostic test is needed for screening snakes that are at risk of having IBD. In this study, despite difficulties in solubilizing semi-purified inclusion bodies, utilizing hybridoma technology a mouse anti-IBD protein monoclonal antibody (MAB) was produced. The antigenic specificity of the antibody was confirmed and validated by western blots, enzyme-linked immunosorbent assay, immuno-transmission electron microscopy, and immunohistochemical staining. Paraffin embedded tissues of IBD positive and negative boa constrictors (n=94) collected from 1990 to 2011 were tested with immunohistochemical staining. In boa constrictors, the anti-IBDP MAB had a sensitivity of 83% and specificity of 100% in detecting IBD. The antibody also cross-reacted with IBD inclusion bodies in carpet pythons (Morelia spilota) and a ball python (python regius). This validated antibody can serve as a tool for the development of ante-mortem immunodiagnostic tests for IBD. PMID:24340066

This paper describes the use of electro-hydrodynamic actuation to control the transition between three major flow patterns of an aqueous-oil Newtonian flow in a microchannel: droplets, beads-on-a-string (BOAS), and multi-stream laminar flow. We observed interesting transitional flow patterns between droplets and BOAS as the electric field was modulated. The ability to control flow patterns of a two-phase fluid in a microchannel adds to the microfluidic tool box and improves our understanding of this interesting fluid behavior.

Sporamins are tuberous storage proteins and account for 80% of soluble protein in sweet potato tubers with trypsin-inhibitory activity. The expression of sporamin protein in transgenic Chinese kale (line BoA 3-1) conferred insecticidal activity toward corn earworm [ Helicoverpa armigera (Hubner)] in a previous report. In this study, we present a preliminary safety assessment of transgenic Chinese kale BoA 3-1. Bioinformatic and simulated gastric fluid (SGF) analyses were performed to evaluate the allergenicity of sporamin protein. The substantial equivalence between transgenic Chinese kale and its wild-type host has been demonstrated by the comparison of important constituents. A reliable real-time polymerase chain reaction (PCR) detection method was also developed to control sample quality. Despite the results of most evaluations in this study being negative, the safety of sporamin in transgenic Chinese kale BoA 3-1 was uncluded because of the allergenic risk revealed by bioinformatic analysis.

The superconductive operating mode represents a thermal equilibrium that can tolerate a certain amount of disturbance before it is lost. The basin of attraction (BOA), in many ways equivalent to a potential well, is a measure of the size of disturbance needed to lift the device from the superconductive into a resistive operating mode. The BOA for a simple geometry is calculated and discussed. Experimental results are reported, showing how the concept is used to gain information on the disturbances occurring in a superconducting device

The blood parasites from the genus Hepatozoon Miller, 1908 (Apicomplexa: Adeleida: Hepatozoidae) represent the most common intracellular protozoan parasites found in snakes. In the present study, we examined 209 individuals of snakes, from different zoogeographical regions (Africa, America, Asia and Europe), for the occurrence of blood parasites using both molecular and microscopic examination methods, and assess phylogenetic relationships of all Hepatozoon parasites from snakes for the first time. In total, 178 blood smears obtained from 209 individuals, representing 40 species, were examined, from which Hepatozoon unicellular parasites were found in 26 samples (14·6% prevalence). Out of 180 samples tested by molecular method polymerase chain reaction (PCR), the presence of parasites was observed in 21 individuals (prevalence 11·6%): 14 snakes from Africa belonging to six genera (Dendroaspis, Dispholidus, Mehelya, Naja, Philothamnus and Python), five snakes from Asia from the genus Morelia and two snakes from America, from two genera (Coluber and Corallus). The intensity of infection varied from one to 1433 infected cells per 10 000 erythrocytes. Results of phylogenetic analyses (Bayesian and Maximum Likelihood) revealed the existence of five haplotypes divided into four main lineages. The present data also indicate neither geographical pattern of studied Hepatozoon sp., nor congruency in the host association.

Rust fungi are obligate pathogens with multiple life stages often including different spore types and multiple plant hosts. While individual rust pathogens are often associated with specific plants, a wide range of plant species are infected with rust fungi. To study the interactions between these important pathogenic fungi and their host plants, one must be able to differentiate fungal tissue from plant tissue. This can be accomplished using the In situ hybridization (ISH) protocol described here. To validate reproducibility using the ISH protocol, samples of Chrysanthemum × morifolium infected with Puccinia horiana, Gladiolus × hortulanus infected with Uromyces transversalis and Glycine max infected with Phakopsora pachyrhizi were tested alongside uninfected leaf tissue samples. The results of these tests show that this technique clearly distinguishes between rust pathogens and their respective host plant tissues. This ISH protocol is applicable to rust fungi and potentially other plant pathogenic fungi as well. It has been shown here that this protocol can be applied to pathogens from different genera of rust fungi with no background staining of plant tissue. We encourage the use of this protocol for the study of plant pathogenic fungi in paraffin embedded sections of host plant tissue.

A qualidade e a segurança dos alimentos estão associadas às boas práticas de produção (BPP. A implantação das BPP resulta na redução do número de microrganismos do leite levando a uma melhor qualidade microbiológica e maior vida de prateleira do produto final. O objetivo deste trabalho foi avaliar o impacto da implantação de boas práticas de ordenha na melhoria da qualidade microbiológica do leite, visando atingir os padrões estabelecidos pela Instrução Normativa 51. Foram aplicadas diferentes práticas de ordenha nos principais pontos de contaminação, identificados previamente, em quatro propriedades do Agreste Pernambucano. As práticas foram avaliadas através da enumeração de microrganismos indicadores aeróbios mesófilos, psicrotróficos, estafilococos coagulase positivos, coliformes totais e Escherichia coli antes e após aplicação das práticas. As práticas adotadas foram: desprezo dos três primeiros jatos de leite, imersão dos tetos em solução clorada, higienização vigorosa e posterior inversão dos latões e baldes para eliminação da água residual. Os resultados demonstram com aplicação das práticas redução média de 99,9% de microrganismos aeróbios mesófilos no leite. As práticas indicadas são simples, eficientes, de fácil incorporação na rotina da ordenha em qualquer situação de tecnificação das propriedades e não requerem gastos com instalações.

Resection and Primary Closure of Edematous Glossoepiglottic Mucosa in a Dog Causing Laryngeal Obstruction.

Schabbing, Kevin J; Seaman, Jeffrey A

An approximately 22 mo old male neutered English bulldog was evaluated for acute onset of dyspnea with suspected brachycephalic obstructive airway syndrome (BOAS). Laryngoscopic exam revealed diffuse, severe edema and static displacement of redundant glossoepiglottic (GE) mucosa causing complete obstruction of the larynx and epiglottic entrapment. Static displacement of the GE mucosa was observed and determined to be the overriding component of dyspnea in this patient with BOAS. Resection and primary closure with two separate, simple continuous sutures of the GE mucosa were performed. Resection and primary closure of the GE mucosa resolved the acute onset of dyspnea in this patient. Surgical correction of the stenotic nares, elongated soft palate, and everted laryngeal saccules were performed under the same anesthetic procedure. Static displacement of the GE mucosa may occur in patients with BOAS. Surgical resection and closure of the GE mucosa resolved this patient's dyspnea and is recommended in airway obstruction. It remains to be determined if primary closure and subsequent tensioning or scar tissue of the GE mucosa results in further complications related to restricted epiglottic movement.

The relaxivity and transmetallation of two lipophilic paramagnetic chelates incorporated onto perfluorocarbon nanoparticles, i.e., gadolinium-methoxy-tetraazacyclododecane-tetraacetic acid phosphatidylethanolamine (Gd-MeO-DOTA-PE) and gadolinium-methoxy-tetraazacyclododecane-tetraacetic acid triglycine phosphatidylethanolamine (Gd-MeO-DOTA-triglycine-PE (Gd-MeO-DOTA-triglycine-PE)), were compared to a prototypic gadolinium-diethylene-triamine-pentaacetic acid bis-oleate (Gd-DTPA-BOA) paramagnetic formulation. Nanoparticles with MeO-DOTA-based chelates demonstrated higher relaxivity (40% higher for Gd-MeO-DOTA-PE and 55% higher for Gd-MeO-DOTA-triglycine-PE) and less transmetallation than the original Gd-DTPA-BOA-based agent.

Nowadays are observed an increase in the finding of certain wild animals in urban areas, due to environmental changes caused by deforestation and economic use of natural areas. It causes disappearance of usual prey and forces these animals, including snakes, to migrate to urban areas, becoming vulnerable to injuries caused by aggressions, car accidents and capture. Mandibular and maxillar fractures are common in many animal species, representing about 3-6% of all bone fractures in dogs and ca...

Captivity of non-venomous snakes such as python and boa are common in zoos, aquariums and as pets in households. Poor captivity conditions expose these reptiles to numerous pathogens which may result in disease conditions. The purpose of this study was to investigate the common bacteria isolated from necropsied captive snakes in Malaysia over a five year period. A total of 27 snake carcasses presented for necropsy at the Universiti Putra Malaysia (UPM) were used in this survey. Samples were aseptically obtained at necropsy from different organs/tissues (lung, liver, heart, kindey, oesophagus, lymph node, stomach, spinal cord, spleen, intestine) and cultured onto 5% blood and McConkey agar, respectively. Gram staining, morphological evaluation and biochemical test such as oxidase, catalase and coagulase were used to tentatively identify the presumptive bacterial isolates. Pythons had the highest number of cases (81.3%) followed by anaconda (14.8%) and boa (3.7%). Mixed infection accounted for 81.5% in all snakes and was highest in pythons (63%). However, single infection was only observed in pythons (18.5%). A total of 82.7%, 95.4% and 100% of the bacterial isolates from python, anaconda and boa, respectively were gram negative. Aeromonas spp was the most frequently isolated bacteria in pythons and anaconda with incidences of 25 (18%) and 8 (36.6%) with no difference (p > 0.05) in incidence, respectively, while Salmonella spp was the most frequently isolated in boa and significantly higher (p snakes have public health importance and have been incriminated in human infections worldwide.

The search for biomarkers of aging (BoAs) has been largely unsuccessful to-date and there is widespread skepticism about the prospects of finding any that satisfy the criteria developed by the American Federation of Aging Research. This may be because the criteria are too strict or because a composite measure might be more appropriate. Telomere length has attracted a great deal of attention as a candidate BoA. We investigate whether it meets the criteria to be considered as a single biomarker of aging, and whether it makes a useful contribution to a composite measure. Using data from a large population based study, we show that telomere length is associated with age, with several measures of physical and cognitive functioning that are related to normal aging, and with three measures of overall health. In the majority of cases, telomere length adds predictive power to that of age, although it was not nearly as good a predictor overall. We used principal components analysis to form two composites from the measures of functioning, one including telomere length and the other not including it. These composite BoAs were better predictors of the health outcomes than chronological age. There was little difference between the two composites. Telomere length does not satisfy the strict criteria for a BoA, but does add predictive power to that of chronological age. Equivocal results from previous studies might be due to lack of power or the choice of measures examined together with a focus on single biomarkers. Composite biomarkers of aging have the potential to outperform age and should be considered for future research in this area.

Stark, David J.; Yin, Lin; Albright, Brian J.; Nystrom, William; Bird, Robert

2018-04-01

We present a particle-in-cell study of linearly polarized laser-ion acceleration systems, in which we use both two-dimensional (2D) and three-dimensional (3D) simulations to characterize the ion acceleration mechanisms in targets which become transparent to the laser pulse during irradiation. First, we perform a target length scan to optimize the peak ion energies in both 2D and 3D, and the predictive capabilities of 2D simulations are discussed. Tracer analysis allows us to isolate the acceleration into stages of target normal sheath acceleration (TNSA), hole boring (HB), and break-out afterburner (BOA) acceleration, which vary in effectiveness based on the simulation parameters. The thinnest targets reveal that enhanced TNSA is responsible for accelerating the most energetic ions, whereas the thickest targets have ions undergoing successive phases of HB and TNSA (in 2D) or BOA and TNSA (in 3D); HB is not observed to be a dominant acceleration mechanism in the 3D simulations. It is in the intermediate optimal regime, both when the laser breaks through the target with appreciable amplitude and when there is enough plasma to form a sustained high density flow, that BOA is most effective and is responsible for the most energetic ions. Eliminating the transverse laser spot size effects by performing a plane wave simulation, we can isolate with greater confidence the underlying physics behind the ion dynamics we observe. Specifically, supplemented by wavelet and FFT analyses, we match the post-transparency BOA acceleration with a wave-particle resonance with a high-amplitude low-frequency electrostatic wave of increasing phase velocity, consistent with that predicted by the Buneman instability.

Cryptosporidium is an important pathogen causing gastrointestinal disease in snakes and is distributed worldwide. The main objectives of this study were to detect and identify Cryptosporidium species in captive snakes from exotic pet shops and snake farms in Thailand. In total, 165 fecal samples were examined from 8 snake species, boa constrictor (Boa constrictor constrictor), corn snake (Elaphe guttata), ball python (Python regius), milk snake (Lampropeltis triangulum), king snake (Lampropeltis getula), rock python (Python sebae), rainbow boa (Epicrates cenchria), and carpet python (Morelia spilota). Cryptosporidium oocysts were examined using the dimethyl sulfoxide (DMSO)-modified acid-fast staining and a molecular method based on nested-PCR, PCR-RFLP analysis, and sequencing amplification of the SSU rRNA gene. DMSO-modified acid-fast staining revealed the presence of Cryptosporidium oocysts in 12 out of 165 (7.3%) samples, whereas PCR produced positive results in 40 (24.2%) samples. Molecular characterization indicated the presence of Cryptosporidium parvum (mouse genotype) as the most common species in 24 samples (60%) from 5 species of snake followed by Cryptosporidium serpentis in 9 samples (22.5%) from 2 species of snake and Cryptosporidium muris in 3 samples (7.5%) from P. regius.

Operation notes are an important part of medical records for clinical, academic and medicolegal reasons. This study audited the quality of operative note keeping for total knee replacements against the standards set by the British Orthopaedic Association (BOA). A prospective review of all patients undergoing total knee replacement at a district general hospital over 8 months. Data recorded were compared with those required by the BOA good-practice guidelines. Change in practice was implemented and the audit cycle completed. Data were statistically analysed. A total of 129 operation notes were reviewed. There was a significant improvement in the mean number of data points recorded from 9.6 to 13.1. The least well recorded data were diagnosis, description of findings, alignment and postoperative flexion range. All had a significant improvement except description of findings. The operating surgeon writing the note improved from 56% to 67%. Detailed postoperative instructions also improved in quality. Surgeon education and the use of a checklist produce better quality total knee replacement operation notes in line with BOA guidelines. Further improvements may be made by making the data points part of the operation note itself.

Full Text Available RESUMO: Por serem frequentes na clínica de animais silvestres, faz-se necessária a manipulação de jiboias e para isso, indispensável o conhecimento sobre as manobras precisas para o tratamento das possíveis afecções. Quando se opta pela contenção química, ou pela realização de procedimentos cirúrgicos, um dos fármacos utilizados na anestesia de serpentes é a cetamina. Viu-se a necessidade de buscar uma via alternativa, semelhante em eficácia às tradicionais para a contenção química, porém que minimizasse os riscos e efeitos adversos encontrados na sua execução. O presente trabalho sugere que a via retal seja esta alternativa, por isso, treze jiboias foram submetidas à administração de 70mg/kg de cloridrato de cetamina, com sonda uretral, através da cloaca até o cólon-reto. Foram avaliados, nos tempos 0, 10, 20, 30, 40, 50, 60, 70, 80, 90 e 120 minutos, a partir da administração do fármaco, os seguintes parâmetros: frequência cardíaca, relaxamento muscular e mobilidade, resistência à contenção ou manipulação e reação postural de endireitamento. Foi realizada coleta de 0,5mL de sangue por punção do seio venoso paravertebral cervical, antes da administração do fármaco, no dia seguinte e após nove dias. Foram dosadas as concentrações plasmáticas de cálcio, fósforo e ácido úrico de todos os exemplares a fim de verificar o perfil bioquímico renal e avaliar a influência do fármaco neste sistema. Não foram observadas alterações bioquímicas plasmáticas durante o período de avaliação. Foi possível promover a contenção química das jiboias Boa constrictor, utilizando cloridrato de cetamina pela via cólon-retal.

O objetivo deste trabalho foi avaliar os possíveis impactos da aplicação do efluente proveniente da suinocultura, após seu tratamento, nos atributos químicos do solo, em área cultivada com algodão. O experimento foi realizado no Perímetro Irrigado Formoso, no município de Bom Jesus da Lapa, BA, em área experimental da Companhia de Desenvolvimento dos Vales do São Francisco e do Parnaíba - CODEVASF. Foram testados cinco tratamentos: MC - manejo convencional = água de "boa qualidade" + adubação química; ET100 = 100 % de efluente tratado; ET75:25 = 75 % de efluente tratado + 25 % de água boa; ET50:50 = 50 % de efluente tratado + 50 % de água boa; ET25:75 = 25 % de efluente tratado + 75 % de água boa. O delineamento experimental foi em blocos ao acaso com quatro repetições. Os atributos químicos do solo avaliados foram: pH, condutividade elétrica, teores de N, P, K, Ca, Mg, Na, Zn, Fe, Mn e Cu. Em geral, quanto aos atributos químicos do solo, a adoção do manejo com efluente tratado apresentou resultados semelhantes aos obtidos com o MC, favorecendo a melhoria da fertilidade do solo e constituindo-se em uma fonte alternativa de fertilização de baixo custo. O efluente tratado, independentemente do fator de diluição, também demonstrou ser uma fonte alternativa de água.

Periodic orbits of the hydrogen molecular ion and their quantization

Duan, Y.; Yuan, J.; Bao, C.

1995-01-01

In a classical study of the hydrogen molecular ion beyond the Born-Oppenheimer approximation (BOA), we have found that segments of trajectories resemble that of the Born-Oppenheimer approximation periodic orbits. The importance of this fact to the classical understanding of chemical bonding leads us to a systematic study of the periodic orbits of the planar hydrogen molecular ion within the BOA. Besides introducing a classification scheme for periodic orbits, we discuss the convergence properties of families of periodic orbits and their bifurcation patterns according to their types. Semiclassical calculations of the density of states based on these periodic orbits yield results in agreement with the exact quantum eigenvalues of the hydrogen molecular ion system

Semiclassical approximations for gravity and the issue of backreaction

International Nuclear Information System (INIS)

Padmanabhan, T.

1989-01-01

Semiclassical approximations, which are useful in the study of a quantum system interacting with a classical system, are studied and compared. In particular, we consider the Born-Oppenheimer approximation (BOA) (corresponding to G → O at fixed ℎ), the effective action approach (ℎ → O at fixed G) and their combinations. We show that in the strict BOA limit there is no backreaction on gravity. In the effective action approach one can obtain a semi-classical description of gravity, if certain stringent requirements are satisfied. In most situations of interest these conditions will not be met and the O(ℎ) contribution from gravitons will be comparable to that from quantum fields. (author)

During aging processing, black carbon (also called soot) particles may tend to be mixed with other aerosols, and highly influence their radiative forcing. In this study, freshly emitted soot particles were simulated as fractal aggregates composed of small spherical primary monomers. After aging in the atmosphere, soot monomers were coated by a thinly layer of sulfate as thinly coated soot particles. These soot particles were entirely embedded into large sulfate particle by further aging, and becoming heavily coated soot particles. In clear-sky conditions, black carbon radiative forcing with different aging states were investigated for the bottom and top of atmosphere (BOA and TOA). The simulations showed that black carbon radiative forcing increased at BOA and decreased at TOA after their aging processes. Thinly and heavily coated states increased up to ~12% and ~35% black carbon radiative forcing at BOA, and black carbon radiative forcing at TOA can reach to ~20% and ~100% smaller for thinly and heavily coated states than those of freshly emitted states, respectively. The effect of aging states of black carbon radiative forcing was varied with surface albedo, aerosol optical depth and solar zenith angles. These findings would be helpful for the assessments of climate change.

A mechanism is proposed to enhance a proton acceleration field in laser plasma interaction. A double-layer plasma with different densities is illuminated by an intense short pulse. Electrons are accelerated to a high energy in the first layer by the wakefield. The electrons accelerated by the laser wakefield induce the enhanced target normal sheath (TNSA) and breakout afterburner (BOA) accelerations through the second layer. The maximum proton energy reaches about 1 GeV, and the total charge with an energy higher than 100 MeV is about several tens of μC/μm. Both the acceleration gradient and laser energy transfer efficiency are higher than those in single-target-based TNSA or BOA. The model has been verified by 2.5D-PIC simulations

ASSESSMENT OF BOTTOM-OF-ATMOSPHERE REFLECTANCE IN LIDAR DATA AS REFERENCE FOR HYPERSPECTRAL IMAGERY

Full Text Available While airborne lidar has confirmed its leading role in delivering high-resolution 3D topographic information during the last decade, its radiometric potential has not yet been fully exploited. However, with the increasing availability of commercial lidar systems which (a make use of full-waveform information and (b operate at several wavelengths simultaneously, this potential is increasing as well. Radiometric calibration of the full-waveform information mentioned before allows for the derivation of physical target surface parameters such as the backscatter coefficient and a diffuse reflectance value at bottom of atmosphere (BOA, i.e. the target surface. With lidar being an active remote sensing technique, these parameters can be derived from lidar data itself, accompanied by the measurement or estimation of reference data for diffuse reflectance. In contrast to this, such a radiometric calibration for passive hyperspectral imagery (HSI requires the knowledge and/or estimation of much more unknowns. However, in case of corresponding wavelength(s radiometrically calibrated lidar datasets can deliver an areawide reference for BOA reflectance. This paper presents criteria to check where the assumption of diffuse BOA reflectance behaviour is fulfilled and how these criteria are assessed in lidar data; the assessment is illustrated by an extended lidar dataset. Moreover, for this lidar dataset and an HSI dataset recorded over the same area, the corresponding reflectance values are compared for different surface types.

Automated global structure extraction for effective local building block processing in XCS.

Learning Classifier Systems (LCSs), such as the accuracy-based XCS, evolve distributed problem solutions represented by a population of rules. During evolution, features are specialized, propagated, and recombined to provide increasingly accurate subsolutions. Recently, it was shown that, as in conventional genetic algorithms (GAs), some problems require efficient processing of subsets of features to find problem solutions efficiently. In such problems, standard variation operators of genetic and evolutionary algorithms used in LCSs suffer from potential disruption of groups of interacting features, resulting in poor performance. This paper introduces efficient crossover operators to XCS by incorporating techniques derived from competent GAs: the extended compact GA (ECGA) and the Bayesian optimization algorithm (BOA). Instead of simple crossover operators such as uniform crossover or one-point crossover, ECGA or BOA-derived mechanisms are used to build a probabilistic model of the global population and to generate offspring classifiers locally using the model. Several offspring generation variations are introduced and evaluated. The results show that it is possible to achieve performance similar to runs with an informed crossover operator that is specifically designed to yield ideal problem-dependent exploration, exploiting provided problem structure information. Thus, we create the first competent LCSs, XCS/ECGA and XCS/BOA, that detect dependency structures online and propagate corresponding lower-level dependency structures effectively without any information about these structures given in advance.

The instantaneous ΔF averages obtained vary from −122 ± 37 Wm⁻² (aerosol optical depth, AOD, at 0.55 μm, 0.85 ± 0.45 at the BOA for the mixture of desert mineral dust and biomass burning aerosols in West Africa and −42 ± 22 Wm⁻² (AOD = 0.9 ± 0.5 at the TOA for the pure mineral dust also in this region up to −6 ± 3 Wm⁻² and −4 ± 2 Wm⁻² (AOD = 0.03 ± 0.02 at the BOA and the TOA, respectively, for free troposphere conditions. This last result may be taken as reference on a global scale. Furthermore, we observe that the more absorbing aerosols are overall more efficient at the BOA in contrast to at the TOA, where they backscatter less solar energy into the space. The analysis of the radiative balance at the TOA shows that, together with the amount of aerosols and their absorptive capacity, it is essential to consider the surface albedo of the region on which they are. Thus, we document that in regions with high surface reflectivity (deserts and snow conditions atmospheric aerosols lead to a warming of the Earth-atmosphere system.

Environmental DNA (eDNA sampling improves occurrence and detection estimates of invasive burmese pythons.

Full Text Available Environmental DNA (eDNA methods are used to detect DNA that is shed into the aquatic environment by cryptic or low density species. Applied in eDNA studies, occupancy models can be used to estimate occurrence and detection probabilities and thereby account for imperfect detection. However, occupancy terminology has been applied inconsistently in eDNA studies, and many have calculated occurrence probabilities while not considering the effects of imperfect detection. Low detection of invasive giant constrictors using visual surveys and traps has hampered the estimation of occupancy and detection estimates needed for population management in southern Florida, USA. Giant constrictor snakes pose a threat to native species and the ecological restoration of the Florida Everglades. To assist with detection, we developed species-specific eDNA assays using quantitative PCR (qPCR for the Burmese python (Python molurus bivittatus, Northern African python (P. sebae, boa constrictor (Boa constrictor, and the green (Eunectes murinus and yellow anaconda (E. notaeus. Burmese pythons, Northern African pythons, and boa constrictors are established and reproducing, while the green and yellow anaconda have the potential to become established. We validated the python and boa constrictor assays using laboratory trials and tested all species in 21 field locations distributed in eight southern Florida regions. Burmese python eDNA was detected in 37 of 63 field sampling events; however, the other species were not detected. Although eDNA was heterogeneously distributed in the environment, occupancy models were able to provide the first estimates of detection probabilities, which were greater than 91%. Burmese python eDNA was detected along the leading northern edge of the known population boundary. The development of informative detection tools and eDNA occupancy models can improve conservation efforts in southern Florida and support more extensive studies of invasive

Full Text Available In this article I focus on comments raised by the presentation of Andréa Lobo in the Cycle of debates: Diálogos Brasil-Cabo Verde (Dialogues Brazil-Cape Verde. From an ethnographic study made at an institution of child protection, located on Yeu island (France, it offers some counterpoints between these two ethnographic contexts, on the Boa Vista and Yeu islands. Therefore, insularity, child mobility and rights of the child are issues addressed at the intersection of studies on kinship and anthropology of childhood. This exercise highlights the relative social isolation that brings families called "single-parent in difficulty" to the institution on Yeu island, in contrast to the abundance of relationships in which child mobility is central to the dynamics of kinship and relatedness on Boa Vista island.

Safety-oriented global analysis of reactor dynamics

International Nuclear Information System (INIS)

Belhadj, M.; Aldemir, T.

1992-01-01

It is well known that the asymptotic solutions of the non-linear systems encountered in reactor dynamics can change from stable to periodic or from periodic to chaotic with a very small change in system parameters and/or initial conditions. In that respect, determination of the domains of attraction (DOAs) in the state-space that contains the asymptotic solutions and the identification of the basins of attraction (BOAs) and lead to these DOAs usually requires a global analysis of reactor dynamics (as opposed to a local analysis through perturbation theory). From the standpoint of safety, the DOAs indicate whether the reactor behavior remains within the imposed constraints or not, and the BOAs show which initial conditions lead to safe operation. Due to the lack of a general theory, often the only feasible method for the global analysis of nonlinear systems is the direct integration of governing equations. However, direct integration can be computationally prohibitive, particularly if there is uncertainty on the values of the system parameters to be used in the analysis, and/or asymptotic system behavior is chaotic. In a recent study, a global analysis algorithm was presented to determine the structure of DOAs (and their probability distribution when there is uncertainty on the system parameters) more quickly than by direct integration. This paper shows how the new algorithm can be expanded to determine the BOAs of reactor dynamics equations as well as their DOAs

A collimated ion beam is generated through the interaction between ultra-intense laser pulse and a double layer plasma. The maximum energy is above 1 GeV and the total charge of high energy protons is about several tens of nC/μm. The double layer plasma is combined with an underdense plasma and a thin overdense one. The wakefield traps and accelerates a bunch of electrons to high energy in the first underdense slab. When the well collimated electron beam accelerated by the wakefield penetrates through the second overdense slab, it enhances target normal sheath acceleration (TNSA) and breakout after-burner (BOA) regimes. The mechanism is simulated and analyzed by 2.5 dimensional Particle-in-cell code. Compared with single target TNSA or BOA, both the acceleration gradient and energy transfer efficiency are higher in the double layer regime. (paper)

Carnegie Mellon University (CMU) is developing novel robotic and user interface systems to assist in the cleanup activities undertaken by the U.S. Department of Energy (DOE). Under DOE's EM-50 funding and administered by the Federal Energy Technology Center (FETC), CMU has developed a novel asbestos pipe-insulation abatement robot system, called BOA, and a novel generic user interface control and training console, dubbed RoboCon. The use of BOA will allow the speedier abatement of the vast DOE piping networks clad with hazardous and contaminated asbestos insulation by which overall job costs can be reduced by as much as 50%. RoboCon will allow the DOE to evaluate different remote and robotic system technologies from the overall man-machine performance standpoint, as well as provide a standardized training platform for training site operators in the operation of remote and robotic equipment

The Born-Oppenheimer approximation (BOA) provides the foundation for virtually all computational studies of chemical binding and reactivity, and it is the justification for the widely used "balls and springs" picture of molecules. The BOA assumes that nuclei effectively stand still on the timescale of electronic motion, due to their large masses relative to electrons. This implies electrons never change their energy quantum state. When molecules react, atoms must move, meaning that electrons may become excited in violation of the BOA. Such electronic excitation is clearly seen for: ( i ) Schottky diodes where H adsorption at Ag surfaces produces electrical "chemicurrent;" ( ii ) Au-based metal-insulator-metal (MIM) devices, where chemicurrents arise from H-H surface recombination; and ( iii ) Inelastic energy transfer, where H collisions with Au surfaces show H-atom translation excites the metal's electrons. As part of this work, we report isotopically selective hydrogen/deuterium (H/D) translational inelasticity measurements in collisions with Ag and Au. Together, these experiments provide an opportunity to test new theories that simultaneously describe both nuclear and electronic motion, a standing challenge to the field. Here, we show results of a recently developed first-principles theory that quantitatively explains both inelastic scattering experiments that probe nuclear motion and chemicurrent experiments that probe electronic excitation. The theory explains the magnitude of chemicurrents on Ag Schottky diodes and resolves an apparent paradox--chemicurrents exhibit a much larger isotope effect than does H/D inelastic scattering. It also explains why, unlike Ag-based Schottky diodes, Au-based MIM devices are insensitive to H adsorption.

An approximately 500-base pair fragment of 18S rDNA common to Hepatozoon spp. and some other apicomplexans was amplified and sequenced from the tissues or blood of 16 vertebrate host species from the southern United States, including 1 opossum (Didelphis virginiana), 2 bobcats (Lynx rufus), 1 domestic cat (Felis catus), 3 coyotes (Canis latrans), 1 gray fox (Urocyon cinereoargenteus), 4 raccoons (Procyon lotor), 1 pet boa constrictor (Boa constrictor imperator), 1 swamp rabbit (Sylvilagus aquaticus), 1 cottontail rabbit (Sylvilagus floridanus), 4 woodrats (Neotoma fuscipes and Neotoma micropus), 3 white-footed mice (Peromyscus leucopus), 8 cotton rats (Sigmodon hispidus), 1 cotton mouse (Peromyscus gossypinus), 1 eastern grey squirrel (Sciurus carolinensis), and 1 woodchuck (Marmota monax). Phylogenetic analyses and comparison with sequences in the existing database revealed distinct groups of Hepatozoon spp., with clusters formed by sequences obtained from scavengers and carnivores (opossum, raccoons, canids, and felids) and those obtained from rodents. Surprisingly, Hepatozoon spp. sequences from wild rabbits were most closely related to sequences obtained from carnivores (97.2% identical), and the sequence from the boa constrictor was most closely related to the rodent cluster (97.4% identical). These data are consistent with recent work identifying prey-predator transmission cycles in Hepatozoon spp. and suggest this pattern may be more common than previously recognized.

On realistic size equivalence and shape of spheroidal Saharan mineral dust particles applied in solar and thermal radiative transfer calculations

Directory of Open Access Journals (Sweden)

Full Text Available Realistic size equivalence and shape of Saharan mineral dust particles are derived from in-situ particle, lidar and sun photometer measurements during SAMUM-1 in Morocco (19 May 2006, dealing with measured size- and altitude-resolved axis ratio distributions of assumed spheroidal model particles. The data were applied in optical property, radiative effect, forcing and heating effect simulations to quantify the realistic impact of particle non-sphericity. It turned out that volume-to-surface equivalent spheroids with prolate shape are most realistic: particle non-sphericity only slightly affects single scattering albedo and asymmetry parameter but may enhance extinction coefficient by up to 10 %. At the bottom of the atmosphere (BOA the Saharan mineral dust always leads to a loss of solar radiation, while the sign of the forcing at the top of the atmosphere (TOA depends on surface albedo: solar cooling/warming over a mean ocean/land surface. In the thermal spectral range the dust inhibits the emission of radiation to space and warms the BOA. The most realistic case of particle non-sphericity causes changes of total (solar plus thermal forcing by 55/5 % at the TOA over ocean/land and 15 % at the BOA over both land and ocean and enhances total radiative heating within the dust plume by up to 20 %. Large dust particles significantly contribute to all the radiative effects reported. They strongly enhance the absorbing properties and forward scattering in the solar and increase predominantly, e.g., the total TOA forcing of the dust over land.

ANTHROPOLOGY AT WAR: ROBERT H. LOWIE AND THE TRANSFORMATION OF THE CULTURE CONCEPT, 1904 to 1954.

Science.gov (United States)

Bargheer, Stefan

2017-03-01

The concept of culture used in American anthropology has fundamentally transformed throughout the first half of the twentieth century. The changing resonance of the work of Robert H. Lowie offers revealing insights into this development. Lowie was part of the first generation of students of Franz Boas that highlighted the importance of individual variation for the study of both primitive and civilized societies. Yet, its initial resonance notwithstanding, the culture concept that prevailed in the discipline went into a different direction as the result of anthropologists' involvement in the war effort. It was advanced by the second generation of Boas' students such as Ruth Benedict and Margaret Mead, who stressed the homogeneity of cultures. The contrast highlights the diversity of approaches available within anthropology in the first half of the century and the crucial impact of World War II in determining which of these possibilities became institutionalized in the decades after the war. © 2017 Wiley Periodicals, Inc.

Formation of beads-on-a-string structures during break-up of viscoelastic filaments

Science.gov (United States)

Bhat, Pradeep P.; Appathurai, Santosh; Harris, Michael T.; Pasquali, Matteo; McKinley, Gareth H.; Basaran, Osman A.

2010-08-01

Break-up of viscoelastic filaments is pervasive in both nature and technology. If a filament is formed by placing a drop of saliva between a thumb and forefinger and is stretched, the filament's morphology close to break-up corresponds to beads of several sizes interconnected by slender threads. Although there is general agreement that formation of such beads-on-a-string (BOAS) structures occurs only for viscoelastic fluids, the underlying physics remains unclear and controversial. The physics leading to the formation of BOAS structures is probed by numerical simulation. Computations reveal that viscoelasticity alone does not give rise to a small, satellite bead between two much larger main beads but that inertia is required for its formation. Viscoelasticity, however, enhances the growth of the bead and delays pinch-off, which leads to a relatively long-lived beaded structure. We also show for the first time theoretically that yet smaller, sub-satellite beads can also form as seen in experiments.

Concentrations and allelopathic effects of benzoxazinoid compounds in soil treated with rye (Secale cereale) cover crop.

Rice, Clifford P; Cai, Guimei; Teasdale, John R

2012-05-09

The concentration of benzoxazinoids (BX) was measured in field soils at selected intervals after rye residue was either incorporated or left on the soil surface. The spectrum of compounds arising in the soil persisted approximately two weeks and was dominated by methoxy containing BX compounds, which were only minor components of the rye foliage. Growth assays with lettuce and smooth pigweed species showed inhibition when treated soils were tested during the first two weeks after rye applications; however, there were no sufficient concentrations of any one BX compound in the soil to explain these affects. Solution applications of two pure BX compounds, benzoxazolin-2(3H)-one (BOA) and 6-methoxy-benzoxazolin-2(3H)-one (MBOA), to the surface of soils revealed that movement into the soil column was minimal (greater than 70% BOA and 97% MBOA remained in the top 1-cm of soil profiles) and that the time course for their complete dissipation was less than 24 h.

Potential use of germicides in vase solutions for gladiolus ‘White Friendship’

Directory of Open Access Journals (Sweden)

Maria Carolina Casares

2017-03-01

Full Text Available Gladiolus (Gladiolus x hortulanus is one of the most important crops for cut flowers worldwide, however having a short longevity. Usually, stems are harvested at the bud stage and need water and carbohydrates to support inflorescence development and to ensure flower quality. Vase solutions can supply these elements. However, sugars may benefit bacterial proliferation, which eventually can block xylem vessels. Bactericides potentially inhibit microorganism proliferation and new compounds are being tested constantly. This experiment was conducted to evaluate ‘White Friendship’ cut gladiolus performance in vase solutions with sodium dichloroisocyanurate dihydrate (Na-DCC, 8-hydroxyquinoline (8-HQ or polymeric biguanide (PB. Inflorescences harvested at commercial maturity were placed in distilled water with 4% w/v of sucrose plus the germicides and kept under ambient conditions. Vase life, inflorescence postharvest development, fresh mass, membrane stability index and water relations were evaluated. There were no visual symptoms of toxicity in the treatments. The highest values of vase life, fully-open flowers, fresh mass and water balance were obtained with the Na-DCC treatment. Inflorescences treated with 8-HQ exhibited the highest values of solution uptake and wilting flowers. PB had a limited effect in gladiolus postharvest since the obtained results were similar to the sucrose alone. There was no effect of germicides on membrane stability index and its reduction was due to flower senescence progress only. Vase solution with Na-DCC plus sucrose improved water balance, increased open flowers, reduced wilting of flowers and fresh mass loss. Therefore, vase solutions with sucrose 4% w/v and Na-DCC enhance postharvest quality of cut gladiolus inflorescences.

Maytenus truncata (Celastraceae) is a plant species widely used in the treatment of ulcers and tumors. Despite the intensive harvest of native specimens in the State of Bahia, northeastern Brazil, there is no information about the genetic variability or structure of this species. Therefore, the goal of this study was to estimate the genetic diversity and population structure of M. truncata based on inter simple sequence repeat (ISSR) molecular markers. The samples comprised specimens from Jequié, Contendas do Sincorá, Boa Nova, and Boa Vista do Tupim in the State of Bahia. After selection of eight ISSR primers, the percentage of polymorphic loci was equal to 96.2% and genetic diversity was 0.3581. The Mantel test revealed positive correlation among genetic and geographic distances (r = 0.5462), but it was not significant (r ≥ 0, P = 0.8365). Even though AMOVA revealed that most variation was found within populations (68%), a high structuring was detected among them (ΦST = 0.31, P extractivism of populations of this species.

Formation of beads-on-a-string structures during the pinch-off of viscoelastic filaments

Science.gov (United States)

Bhat, Pradeep; Appathurai, Santosh; Harris, Michael; Pasquali, Matteo; McKinley, Gareth; Basaran, Osman

2009-11-01

Breakup of liquid filaments is omnipresent in nature and technology. When a filament formed by placing a drop of syrup between a thumb and a forefinger is stretched by pulling apart the two fingers, it resembles a thinning cylinder. If the same experiment is repeated with saliva, the filament's morphology close to pinch-off resembles that of beads of several sizes interconnected by slender threads. Although there is general agreement that formation of such beads-on-a-string (BOAS) morphology only occurs for viscoelastic fluids, the mechanism behind this phenomenon remains unclear and controversial. The physics of formation of BOAS structures is probed here by simulation which reveals that viscoelasticity alone does not give rise to a small, satellite bead between two much larger main drops (beads) but that inertia is required for its formation. Viscoelasticity, however, enhances the growth of the satellite bead and delays pinch-off, which leads to a relatively long-lived, stable beaded filament. The new simulations also show the formation of second-generation sub-satellite beads in certain cases, as observed experimentally but not, heretofore, predicted theoretically.

Relativistic Buneman instability in the laser breakout afterburner

International Nuclear Information System (INIS)

Albright, B. J.; Yin, L.; Bowers, Kevin J.; Hegelich, B. M.; Flippo, K. A.; Kwan, T. J. T.; Fernandez, J. C.

2007-01-01

A new laser-driven ion acceleration mechanism has been identified in particle-in-cell simulations of high-contrast-ratio ultraintense lasers with very thin (10 s of nm) solid targets [Yin et al., Laser and Particle Beams 24, 291 (2006); Yin et al., Phys. Plasmas 13, 072701 (2007)]. After a brief period of target normal sheath acceleration (TNSA), 'enhanced' TNSA follows. In this stage, the laser rapidly heats all the electrons in the target as the target thickness becomes comparable to the skin depth and enhanced acceleration of the ions results. Then, concomitant with the laser penetrating the target, a large accelerating longitudinal electric field is generated that co-moves with the ions. This last phase has been termed the laser 'breakout afterburner' (BOA). Earlier work suggested that the BOA was associated with the Buneman instability that efficiently converts energy from the drift of the electrons into the ions. In this Brief Communication, this conjecture is found to be consistent with particle-in-cell simulation data and the analytic dispersion relation for the relativistic Buneman instability

Ultraintense laser interaction with nanoscale targets: a simple model for layer expansion and ion acceleration

Albright, B J; Yin, L; Hegelich, B M; Bowers, K J; Huang, C; Fernandez, J C; Flippo, K A; Gaillard, S A; Kwan, T J T; Henig, A; Tajima, T; Habs, D; Yan, X Q

2010-01-01

A simple model has been derived for expansion of a thin (up to 100s of nm thickness) target initially of solid density irradiated by an ultraintense laser. In this regime, ion acceleration mechanisms, such as the Break-Out Afterburner (BOA) [1], emerge with the potential for dramatically improved energy, efficiency, and energy spread. Ion beams have been proposed [2] as drivers for fast ignition inertial confinement fusion [3]. Analysis of kinetic simulations of the BOA shows the period of enhanced acceleration occurs between times t 1 , when the target becomes relativistically transparent to the laser, and t 2 , when the target becomes classically underdense and the enhanced acceleration terminates. A simple model for target expansion has been derived that contains early, one-dimensional (1D) expansion of the target and three-dimensional (3D) expansion at late times. The model assumes expansion is slab-like at the instantaneous ion sound speed and requires as input target composition, laser intensity, laser spot area, and the efficiency of laser absorption into electron thermal energy.

Optimization method to determine mass transfer variables in a PWR crud deposition risk assessment tool

International Nuclear Information System (INIS)

Do, Chuong; Hussey, Dennis; Wells, Daniel M.; Epperson, Kenny

2016-01-01

Optimization numerical method was implemented to determine several mass transfer coefficients in a crud-induced power shift risk assessment code. The approach was to utilize a multilevel strategy that targets different model parameters that first changes the major order variables, mass transfer inputs, then calibrates the minor order variables, crud source terms, according to available plant data. In this manner, the mass transfer inputs are effectively simplified as 'dependent' on the crud source terms. Two optimization studies were performed using DAKOTA, a design and analysis toolkit, with the difference between the runs, being the number of model runs using BOA, allowed for adjusting the crud source terms, therefore, reducing the uncertainty with calibration. The result of the first case showed that the current best estimated values for the mass transfer coefficients, which were derived from first principle analysis, can be considered an optimized set. When the run limit of BOA was increased for the second case, an improvement in the prediction was obtained with the results deviating slightly from the best estimated values. (author)

The present work has as objective to present the main bases of 'PAT/IG Project', accomplished in Boa Esperanca Farm (Delfim Moreira - MG), by an accord between Itajuba's Federal University and Mines and Energy Ministry. In a moment that the look for sustainable development is the law in Brazil, low costs and environmental impact alternatives must be prioritized. By this way, the PAT/IG Project continuous the Viana's (1987) works, that developed all Brazilian theoretical bases for using Pumps Working as Turbine (PAT). Besides that, the application of induction motors operating as induction generators will be evaluated, as the velocity control system of the PAT/IG group will be developed. The existing Boa Esperanca Farm's micro power plant will be rebuild ed, to receive a new generating group formed for a PAT and a IG, that will be used as natural sized test workbench of Itajuba's Federal University. At the ending of the project, there will be enough subsidies to prove, in practice, the feasibility presented in laboratorial tests by PAT/IG groups as conventional turbines replacer in micro powerplants.

Full Text Available We described the spatial distribution of fish trophic groups in the Água Boa Stream, MS, Brazil. Specimens were caught using electrofishing in the upper, intermediate and lower stretches of the stream, between March and November 2008. We analyzed 415 stomach contents of 24 species. Detritus/sediment and aquatic invertebrates were the main exploited resources. Ordination analysis categorized the species in six trophic groups. Aquatic invertivores showed the highest richness (10 species, followed by detritivores (08 species, omnivores (03 species, terrestrial invertivores (03 species, algivores (02 species and herbivore (01 species. Three trophic groups occurred in the upper stretch, six in the intermediate and five in the lower. Detritivores, omnivores and algivores showed the highest density, while detritivores and aquatic invertivores presented the highest biomass. Autochthonous resources were particularly important to the studied fish fauna, especially aquatic invertebrates, so, conservation actions reducing the simplification of the habitat by silting and recovering the riparian forest are essential to maintain the ichthyofauna of the Água Boa Stream.

Full Text Available O artigo parte dos pressupostos de que as crianças têm direito e são competentes para falar sobre as suas experiências e de que conhecer suas perspectivas sobre suas experiências educacionais enriquece e amplia o nosso conhecimento sobre elas. As falas produzidas em várias pesquisas que ouviram crianças no Brasil informam, dentre muitas outras coisas que: fazer amigos e brincar é o que mais apreciam; uma alimentação saborosa é muito importante; a boa professora é sensível às suas demandas e não grita nem castiga; não gostam das tarefas que lhes tomam tanto tempo da rotina; e, no caso das crianças negras, enfrentam problemas para construir uma boa imagem de si. São indicações fundamentais para políticas voltadas a essa etapa da educação, como políticas de formação inicial e continuada de professores, de currículo, de construção e reforma de prédios escolares, aquisição de brinquedos e livros infantis.

Snakes mimic earthworms: propulsion using rectilinear travelling waves

Science.gov (United States)

Marvi, Hamidreza; Bridges, Jacob; Hu, David L.

2013-01-01

In rectilinear locomotion, snakes propel themselves using unidirectional travelling waves of muscular contraction, in a style similar to earthworms. In this combined experimental and theoretical study, we film rectilinear locomotion of three species of snakes, including red-tailed boa constrictors, Dumeril's boas and Gaboon vipers. The kinematics of a snake's extension–contraction travelling wave are characterized by wave frequency, amplitude and speed. We find wave frequency increases with increasing body size, an opposite trend than that for legged animals. We predict body speed with 73–97% accuracy using a mathematical model of a one-dimensional n-linked crawler that uses friction as the dominant propulsive force. We apply our model to show snakes have optimal wave frequencies: higher values increase Froude number causing the snake to slip; smaller values decrease thrust and so body speed. Other choices of kinematic variables, such as wave amplitude, are suboptimal and appear to be limited by anatomical constraints. Our model also shows that local body lifting increases a snake's speed by 31 per cent, demonstrating that rectilinear locomotion benefits from vertical motion similar to walking. PMID:23635494

Improving beam spectral and spatial quality by double-foil target in laser ion acceleration for ion-driven fast ignition

International Nuclear Information System (INIS)

Huang, Chenkun; Albright, Brian J.

2010-01-01

Mid-Z ion driven fast ignition inertial fusion requires ion beams of 100s of MeV energy and < 10% energy spread. An overdense run-scale foil target driven by a high intensity laser pulse can produce an ion beam that has attractive properties for this application. The Break Out Afterburner (BOA) is one laser-ion acceleration mechanism proposed to generate such beams, however the late stages of the BOA tend to produce too large of an energy spread. The spectral and spatial qualities of the beam quickly evolve as the ion beam and co-moving electrons continue to interact with the laser. Here we show how use of a second target foil placed behind a nm-scale foil can substantially reduce the temperature of the co-moving electrons and improve the ion beam energy spread. Particle-In-Cell simulations reveal the dynamics of the ion beam under control. Optimal conditions for improving the spectral and spatial spread of the ion beam is explored for current laser and target parameters, leading to generation of ion beams of energy 100s of MeV and 6% energy spread, a vital step for realizing ion-driven fast ignition.

A simple model has been derived for the expansion of a thin (up to 100s of nm thickness), solid-density target driven by an u.ltraintense laser. In this regime, new ion acceleration mechanisms, such as the Break-Out Afterburner (BOA) (1), emerge with the potential to dramatically improve energy, efficiency, and energy spread of laser-driven ion beams. Such beams have been proposed (2) as drivers for fast ignition inertial confinement fusion (3). Analysis of kinetic simulations of the BOA shows two dislinct times that bound the period of enhanced acceleration: t 1 , when the target becomes relativistically transparent to the laser, and t 2 , when the target becomes classically underdense and the enhanced acceleration terminates. A silllple dynamical model for target expansion has been derived that contains both the early, one-dimensional (lD) expansion of the target as well as three-dimensional (3D) expansion of the plasma at late times, The model assumes that expansion is slab-like at the instantaneous ion sound speed and requires as input target composition, laser intensity, laser spot area, and the efficiency of laser absorption into electron thermal energy.

From Nano to Micro: Importance of Structure and Architecture in Spider Silk Adhesives

Science.gov (United States)

Sahni, Vasav; Dhinojwala, Ali

2012-02-01

Spiders have developed outstanding adhesives over millions of years of evolution for prey capture and locomotion. We show that the structure and architecture of these adhesives play an important role in the adhesion. The adhesive produced by orb-weaving spiders to capture prey (viscid glue) is laid on a pair of silk fibers as micron-size glue drops composed of salts and glycoproteins. By stretching single drops, we show that viscid glue behaves like a viscoelastic solid and that elasticity is critical in enhancing adhesion caused by specific adhesive ligands by over 100 times. Comparing viscid glue with gumfoot glue, the glue produced by cob-weavers, the evolutionary descendants of orb-weavers, showed that, in spite of being produced in homologous aggregate glands, gumfoot glue behaves like a viscoelastic liquid. Moreover, gumfoot glue is humidity-resistant and viscid glue is humidity-sensitive. We use a synthetic strategy to spin beads-on-a-string (BOAS) architecture to mimic the adhesive properties of spider silk. Using these mimic threads, we show that the BOAS structure adheres more than a cylindrical structure during contact (collision of prey) and during separation (escape attempt of prey). These results inspire design of novel tunable adhesives.

Reed, R.N.; Kraus, F.

2010-01-01

In the annals of invasive species biology, higher taxa such asmammals, plants and insects have received the lion’s shareof research attention, largely because many of these invadershave demonstrated a remarkable ability to degrade ecosys-tems and cause economic harm. Interest in invasive reptilesand amphibians (collectively ‘herpetofauna’, colloquially‘herps’) has historically lagged but is now garnering in-creased scrutiny as a result of their escalating pace ofinvasion. A few herpetofaunal invaders have received con-siderable attention in scientific and popular accounts, in-cluding the brown treesnakeBoiga irregularison Guam,Burmese pythonPython molurusin Florida, Coqu´ıEleutherodactylus coquiin Hawaii and cane toadBufomarinusin Australia. However, relatively few are aware ofmany emerging and potentially injurious herpetofaunalinvaders, such as Nile monitorsVaranus niloticusin Flor-ida, common kingsnakesLampropeltis getulain the CanaryIslands, boa constrictorsBoa constrictoron Aruba andCozumel, or a variety of giant constrictor snakes in PuertoRico. For the vast majority of the most commonlyintroduced species, real or potential impacts to nativeecosystems or human economic interests are poorly under-stood and incompletely explored; major pathways of intro-duction have only recently been elucidated, and effectivemanagement interventions have been limited (Kraus, 2009).

Representational difference analysis was used to identify strain-specific differences in the pseudoautosomal region (PAR) of mouse X and Y chromosomes. One second generation (C57BL/6 x Mus spretus) x Mus spretus interspecific backcross male carrying the C57BL/6 (B6) PAR was used for tester DNA. DNA from five backcross males from the same generation that were M. spretus-type for the PAR was pooled for the driver. A cloned probe designated B6-38 was recovered that is B6-specific in Southern analysis. Analysis of genomic DNA from several inbred strains of laboratory mice and diverse Mus species and subspecies identified a characteristic Pst I pattern of fragment sizes that is present only in the C57BL family of strains. Hybridization was observed with sequences in DBA/2J and to a limited extent with Mus musculus (PWK strain) and Mus castaneus DNA. No hybridization was observed in DNA of different Mus species, M. spretus, M. hortulanus, and M. caroli. Genetic analyses of B6-38 was conducted using C57BL congenic males that carry M. spretus alleles for distal X chromosome loci and the PAR and outcrosses of heterozygous congenic females with M. spretus. These analyses demonstrated that the B6-38 sequences were inherited with both the X and Y chromosome. B6-38 sequences were genetically mapped as a locus within the PAR using two interspecific backcrosses. The locus defined by B6-38 is designated DXYRp1. Preliminary analyses of recombination between the distal X chromosome gene amelogenin (Amg) and the PAR loci for either TelXY or sex chromosome association (Sxa) suggest that the locus DXYRp1 maps to the distal portion of the PAR.

Assigning breed origin to alleles in crossbred animals.

2016-08-22

For some species, animal production systems are based on the use of crossbreeding to take advantage of the increased performance of crossbred compared to purebred animals. Effects of single nucleotide polymorphisms (SNPs) may differ between purebred and crossbred animals for several reasons: (1) differences in linkage disequilibrium between SNP alleles and a quantitative trait locus; (2) differences in genetic backgrounds (e.g., dominance and epistatic interactions); and (3) differences in environmental conditions, which result in genotype-by-environment interactions. Thus, SNP effects may be breed-specific, which has led to the development of genomic evaluations for crossbred performance that take such effects into account. However, to estimate breed-specific effects, it is necessary to know breed origin of alleles in crossbred animals. Therefore, our aim was to develop an approach for assigning breed origin to alleles of crossbred animals (termed BOA) without information on pedigree and to study its accuracy by considering various factors, including distance between breeds. The BOA approach consists of: (1) phasing genotypes of purebred and crossbred animals; (2) assigning breed origin to phased haplotypes; and (3) assigning breed origin to alleles of crossbred animals based on a library of assigned haplotypes, the breed composition of crossbred animals, and their SNP genotypes. The accuracy of allele assignments was determined for simulated datasets that include crosses between closely-related, distantly-related and unrelated breeds. Across these scenarios, the percentage of alleles of a crossbred animal that were correctly assigned to their breed origin was greater than 90 %, and increased with increasing distance between breeds, while the percentage of incorrectly assigned alleles was always less than 2 %. For the remaining alleles, i.e. 0 to 10 % of all alleles of a crossbred animal, breed origin could not be assigned. The BOA approach accurately assigns

Systematic mutagenesis of genes encoding predicted autotransported proteins of Burkholderia pseudomallei identifies factors mediating virulence in mice, net intracellular replication and a novel protein conferring serum resistance.

Full Text Available Burkholderia pseudomallei is the causative agent of the severe tropical disease melioidosis, which commonly presents as sepsis. The B. pseudomallei K96243 genome encodes eleven predicted autotransporters, a diverse family of secreted and outer membrane proteins often associated with virulence. In a systematic study of these autotransporters, we constructed insertion mutants in each gene predicted to encode an autotransporter and assessed them for three pathogenesis-associated phenotypes: virulence in the BALB/c intra-peritoneal mouse melioidosis model, net intracellular replication in J774.2 murine macrophage-like cells and survival in 45% (v/v normal human serum. From the complete repertoire of eleven autotransporter mutants, we identified eight mutants which exhibited an increase in median lethal dose of 1 to 2-log10 compared to the isogenic parent strain (bcaA, boaA, boaB, bpaA, bpaC, bpaE, bpaF and bimA. Four mutants, all demonstrating attenuation for virulence, exhibited reduced net intracellular replication in J774.2 macrophage-like cells (bimA, boaB, bpaC and bpaE. A single mutant (bpaC was identified that exhibited significantly reduced serum survival compared to wild-type. The bpaC mutant, which demonstrated attenuation for virulence and net intracellular replication, was sensitive to complement-mediated killing via the classical and/or lectin pathway. Serum resistance was rescued by in trans complementation. Subsequently, we expressed recombinant proteins of the passenger domain of four predicted autotransporters representing each of the phenotypic groups identified: those attenuated for virulence (BcaA, those attenuated for virulence and net intracellular replication (BpaE, the BpaC mutant with defects in virulence, net intracellular replication and serum resistance and those displaying wild-type phenotypes (BatA. Only BcaA and BpaE elicited a strong IFN-γ response in a restimulation assay using whole blood from seropositive donors

This has led sociologists to redefine the 'ages' of early childhood. These are: 0-2, the crèche, 2-3, the kindergarten and from three years old on, play school. To this must be added home care with a child-minder for wealthier classes. Based on interviewswith parents, É. Plaisance shows that those involved put freedom of choice first (even when the choices are rare and the weight of evidence underlines that the solution arrived at was the best for them and their child. But the responses also show that they try to inform themselves by ways that favor word of mouth and giveroom for rumor and hearsay. The 'choice' of those involved is constrained, but as if to reassure themselves and to show that they are assuming their responsibility, they willingly describe it as 'free'.

This research aims at analyzing the efficiency of public spending on hospital care and primary education in the State capitals in 2009. We used descriptive research, literature, quantitative and qualitative. Data collection was performed at the STN sites, IBGE, DATASUS, MEC and System FIRJAN. The results revealed that average spending on hospital care amounted to R $ R $ 403,151,579.13, being the capital Macapá with lower allocation of funds for this subfunction and Sao Paulo that with greater allocation of resources. It was further observed that expenditure on primary education were on average R $ 376,799,800.62. São Paulo is the capital with the highest allocation of funds to elementary and Boa Vista which allocated fewer resources in 2009. We conclude that among the 22 capitals analyzed four of them (Florianopolis, Joao Pessoa, São Paulo and Macapa were effective with respect to spending on hospital care and 6 of them (Boa Vista, Manaus, Porto Velho, Rio de Janeiro, Salvador and São Paul were efficient as the application of basic education spending.

Ticks were collected or recorded from 522 individual reptiles on Dominica and from 658 reptiles from the Bahamas. Two species of ticks were collected on Dominica: Amblyomma antillorum and Amblyomma rotundatum. Similarly, 2 species were collected in the Bahamas: Amblyomma albopictum and Amblyomma torrei. On Dominica, A. antillorum was recorded from 517 Lesser Antillean iguanas (Iguana delicatissima), 2 boa constrictors (Boa nebulosa), 1 Antilles snake (Alsophis sibonius), and 1 Dominican ground lizard (Ameiva fuscata), whereas A. rotundatum was recorded from 1 Lesser Antillean skink (Mabuya mabouya). In the Bahamas, A. albopictum was recorded from 131 Andros iguanas (Cyclura cychlura cychlura), 271 Exuma Island iguanas (Cyclura cychlura figginsi), and 1 Andros curlytail lizard (Leiocephalus carinatus coryi), whereas A. torrei was recorded from 255 Exuma Island iguanas. In the Bahamas, A. albopictum parasitized iguanas on Andros Island and the central Exuma Islands, and A. torrei parasitized iguanas in the southern Exumas. An exception to this trend was that A. torrei was collected from iguanas on Pasture Cay in the central Exumas, an anomaly that is explained by the fact that iguanas (with attached ticks) on Pasture Cay were introduced by humans in the past from islands further south. External hyperparasitic larval erythraeid mites ( Leptus sp.) were recorded from A. torrei in the Bahamas.

Seasonal dynamics of Aedes aegypti (Diptera: Culicidae in the northernmost state of Brazil: a likely port-of-entry for dengue virus 4

Full Text Available Roraima is the northernmost state of Brazil, bordering both Venezuela and Guyana. Appropriate climate and vector conditions for dengue transmission together with its proximity to countries where all four dengue serotypes circulate make this state, particularly the capital Boa Vista, strategically important for dengue surveillance in Brazil. Nonetheless, few studies have addressed the population dynamics of Aedes aegypti in Boa Vista. In this study, we report temporal and spatial variations in Ae. aegypti population density using ovitraps in two highly populated neighbourhoods; Centro and Tancredo Neves. In three out of six surveys, Ae. aegypti was present in more than 80% of the sites visited. High presence levels of this mosquito suggest ubiquitous human exposure to the vector, at least during part of the year. The highest infestation rates occurred during the peak of the rainy seasons, but a large presence was also observed during the early dry season (although with more variation among years. Spatial distribution of positive houses changed from a sparse and local pattern to a very dense pattern during the dry-wet season transition. These results suggest that the risk of dengue transmission and the potential for the new serotype invasions are high for most of the year.

Antidiabetic Theory of Superconducting State Transition: Phonons and Strong Electron Correlations the Old Physics and New Aspects

International Nuclear Information System (INIS)

Banacky, P.

2010-01-01

Complex electronic ground state of molecular and solid state system is analyzed on the ab initio level beyond the adiabatic Born-Oppenheimer approximation (BOA). The attention is focused on the band structure fluctuation (BSF) at Fermi level, which is induced by electron-phonon coupling in superconductors, and which is absent in the non-superconducting analogues. The BSF in superconductors results in breakdown of the adiabatic BOA. At these circumstances, chemical potential is substantially reduced and system is stabilized (effect of nuclear dynamics) in the anti adiabatic state at broken symmetry with a gap(s) in one-particle spectrum. Distorted nuclear structure has fluxional character and geometric degeneracy of the anti adiabatic ground state enables formation of mobile bipolarons in real space. It has been shown that an effective attractive e-e interaction (Cooper-pair formation) is in fact correction to electron correlation energy at transition from adiabatic into anti adiabatic ground electronic state. In this respect, Cooper-pair formation is not the primary reason for transition into superconducting state, but it is a consequence of anti adiabatic state formation. It has been shown that thermodynamic properties of system in anti adiabatic state correspond to thermodynamics of superconducting state. Illustrative application of the theory for different types of superconductors is presented.

Enhanced Electron-Phonon Coupling at Metal Surfaces

Energy Technology Data Exchange (ETDEWEB)

Plummer, Ward E.

2010-08-04

The Born-Oppenheimer approximation (BOA) decouples electronic from nuclear motion, providing a focal point for most quantum mechanics textbooks. However, a multitude of important chemical, physical and biological phenomena are driven by violations of this approximation. Vibronic interactions are a necessary ingredient in any process that makes or breaks a covalent bond, for example, conventional catalysis or enzymatically delivered biological reactions. Metastable phenomena associated with defects and dopants in semiconductors, oxides, and glasses entail violation of the BOA. Charge exchange in inorganic polymers, organic slats and biological systems involves charge- induced distortions of the local structure. A classic example is conventional superconductivity, which is driven by the electron-lattice interaction. High-resolution angle-resolved photoemission experiments are yielding new insight into the microscopic origin of electron-phonon coupling (EPC) in anisotropic two-dimensional systems. Our recent surface phonon measurement on the surface of a high-Tc material clearly indicates an important momentum dependent EPC in these materials. In the last few years we have shifted our research focus from solely looking at electron phonon coupling to examining the structure/functionality relationship at the surface of complex transition metal compounds. The investigation on electron phonon coupling has allowed us to move to systems where there is coupling between the lattice, the electrons and the spin.

Allelopathic cover crop of rye for integrated weed control in sustainable agroecosystems

Directory of Open Access Journals (Sweden)

Vincenzo Tabaglio

2013-02-01

Full Text Available The allelopathic potential of rye (Secale cereale L. is mainly due to phytotoxic benzoxazinones, compounds that are produced and accumulated in young tissues to different degrees depending on cultivar and environmental influences. Living rye plants exude low levels of benzoxazinones, while cover crop residues can release from 12 to 20 kg ha–1. This paper summarizes the results obtained from several experiments performed in both controlled and field environments, in which rye was used as a cover crop to control summer weeds in a following maize crop. Significant differences in benzoxazinoid content were detected between rye cultivars. In controlled environments, rye mulches significantly reduced germination of some broadleaf weeds. Germination and seedling growth of Amaranthus retroflexus and Portulaca oleracea were particularly affected by the application of rye mulches, while Chenopodium album was hardly influenced and Abutilon theophrasti was advantaged by the presence of the mulch. With reference to the influence of agronomic factors on the production of benzoxazinoids, nitrogen fertilization increased the content of allelochemicals, although proportionally less than dry matter. The field trial established on no-till maize confirmed the significant weed suppressiveness of rye mulch, both for grass and broadleaf weeds. A significant positive interaction between nitrogen (N fertilization and notillage resulting in the suppression of broadleaf weeds was observed. The different behavior of the weeds in the presence of allelochemicals was explained in terms of differential uptake and translocation capabilities. The four summer weeds tested were able to grow in the presence of low amounts of benzoxazolin-2(3H-one (BOA, between 0.3 and 20 mmol g–1 fresh weight. Although there were considerable differences in their sensitivity to higher BOA concentrations, P. oleracea, A. retroflexus, and Ch. album represented a group of species with a consistent

BOA: Asbestos pipe-insulation removal robot system, Phase 2. Topical report, January--June 1995

Energy Technology Data Exchange (ETDEWEB)

Schempf, H.; Bares, J.E.

1995-06-01

This report explored the regulatory impact and cost-benefit of a robotic thermal asbestos pipe-insulation removal system over the current manual abatement work practice. The authors are currently in the second phase of a two-phase program to develop a robotic asbestos abatement system, comprised of a ground-based support system (including vacuum, fluid delivery, computing/electronics/power, and other subsystems) and several on-pipe removal units, each sized to handle pipes within a given diameter range. The intent of this study was to (i) aid in developing design and operational criteria for the overall system to maximize cost-efficiency, and (ii) to determine the commercial potential of a robotic pipe-insulation abatement system.

Yin, L.; Albright, B. J.; Hegelich, B. M.; Bowers, K. J.; Flippo, K. A.; Kwan, T. J. T.; Fernandez, J. C.

2007-01-01

A new laser-driven ion acceleration mechanism using ultrathin targets has been identified from particle-in-cell simulations. After a brief period of target normal sheath acceleration (TNSA) [S. P. Hatchett et al., Phys. Plasmas 7, 2076 (2000)], two distinct stages follow: first, a period of enhanced TNSA during which the cold electron background converts entirely to hot electrons, and second, the ''laser breakout afterburner'' (BOA) when the laser penetrates to the rear of the target where a localized longitudinal electric field is generated with the location of the peak field co-moving with the ions. During this process, a relativistic electron beam is produced by the ponderomotive drive of the laser. This beam is unstable to a relativistic Buneman instability, which rapidly converts the electron energy into ion energy. This mechanism accelerates ions to much higher energies using laser intensities comparable to earlier TNSA experiments. At a laser intensity of 10 21 W/cm 2 , the carbon ions accelerate as a quasimonoenergetic bunch to 100 s of MeV in the early stages of the BOA with conversion efficiency of order a few percent. Both are an order of magnitude higher than those realized from TNSA in recent experiments [Hegelich et al., Nature 441, 439 (2006)]. The laser-plasma interaction then evolves to produce a quasithermal energy distribution with maximum energy of ∼2 GeV

Full Text Available Sistemas aquáticos que apresentam águas calmas e com região delimitada, por exemplo, lagoas, lagos e pântanos, são denominados ambientes lênticos. O Parque Carlos Alberto de Souza, localizado em Sorocaba-SP, é um dos parques existentes na cidade contendo lago artificial, onde habitam peixes, tartarugas e garças. É frequentado por crianças e adultos para lazer ou prática de exercícios. Sendo assim, uma boa qualidade de água é fundamental para a vida no lago. O objetivo deste trabalho foi analisar a qualidade da água, usando índices de qualidade adotados pela CETESB (Companhia de Tecnologia de Saneamento Ambiental. Os resultados apresentaram valor elevado de coliformes termotolerantes e baixa concentração de oxigênio. Considerando a ponderação dos parâmetros a água foi classificada como boa, porém o índice referente à presença de nutrientes classificou o corpo hídrico como hipertrófico, o que pode causar aflorações de algas e mortandades de peixes. Os resultados representam um alerta quanto à necessidade de monitoramento da qualidade dos ambientes lênticos e a necessitade de alertas à população que frequentam o ambiente.

Full Text Available A crescente geração de efluentes líquidos e o seu lançamento no meio ambiente tem-se constituído numa preocupação mundial devido aos impactos negativos gerados. O objetivo deste trabalho foi avaliar os possíveis impactos da aplicação do efluente proveniente da suinocultura, após seu tratamento, nos atributos químicos do solo, em área cultivada com algodão. O experimento foi realizado no Perímetro Irrigado Formoso, no município de Bom Jesus da Lapa, BA, em área experimental da Companhia de Desenvolvimento dos Vales do São Francisco e do Parnaíba - CODEVASF. Foram testados cinco tratamentos: MC - manejo convencional = água de "boa qualidade" + adubação química; ET100 = 100 % de efluente tratado; ET75:25 = 75 % de efluente tratado + 25 % de água boa; ET50:50 = 50 % de efluente tratado + 50 % de água boa; ET25:75 = 25 % de efluente tratado + 75 % de água boa. O delineamento experimental foi em blocos ao acaso com quatro repetições. Os atributos químicos do solo avaliados foram: pH, condutividade elétrica, teores de N, P, K, Ca, Mg, Na, Zn, Fe, Mn e Cu. Em geral, quanto aos atributos químicos do solo, a adoção do manejo com efluente tratado apresentou resultados semelhantes aos obtidos com o MC, favorecendo a melhoria da fertilidade do solo e constituindo-se em uma fonte alternativa de fertilização de baixo custo. O efluente tratado, independentemente do fator de diluição, também demonstrou ser uma fonte alternativa de água.The negative impacts of the increasing volume of wastewater and of its discharge into the environment have become a worldwide concern.

Local geological dust in the area of Rome (Italy): linking mineral composition, size distribution and optical properties to radiative transfer modelling

Science.gov (United States)

Pietrodangelo, Adriana; Salzano, Roberto; Bassani, Cristiana; Pareti, Salvatore; Perrino, Cinzia

Airborne mineral dust plays a key role in the energy balance of the Earth - atmosphere coupled system. The microphysical and optical properties of dust drive the direct radiative effects and are in turn influenced by the dust mineralogical composition. The latter varies largely, depending on the geology of the source region. Knowledge gaps still exist about relationships between the scattering and absorption of solar and terrestrial radiation by mineral dust and its mineralogical, size distribution and particle morphology features; this also affects the reliability of radiative transfer (RT) modelling estimates (Hansell et al., 2011). In this study, these relationships were investigated focusing on the crustal suspended PM10 dust, sourced from outcropping rocks of the local geological domains around Rome (Latium, Italy). The mineral composition variability of the Latium rocks ranges from the silicate-dominated (volcanics domain) to the calcite-dominated (travertine), through lithological materials composed in different proportions by silicates, silica and calcite, mainly (limestone series, siliciclastic series) (Cosentino et al., 2009). This peculiarity of the Latium region was thus exploited to investigate the behavior of the size distribution, optical properties and radiative transfer at BOA (Bottom Of Atmosphere) of the suspended dust PM10 fraction with the variability of mineral composition. Elemental source profiles of the same dust samples were previously determined (Pietrodangelo et al., 2013). A multi-faceted analysis was performed, and outcomes from the following approaches were merged: individual-particle scanning electron microscopy combined with X-ray energy-dispersive microanalysis (SEM XEDS), bulk mineralogical analysis by X-ray diffraction (XRD), size distribution fit of the individual-particle data set and modelling of the dust optical and radiative properties. To this aim, the 6SV atmospheric radiative transfer code (Kotchenova et al., 2008

Environmental and deteriorating state analyses of the watershed Riacho do Tronco, Boa Vista, PB, Brazil

Full Text Available This study proposes, from the subdivision of the watershed of Riacho do Tronco in eight sub-watersheds, to diagnose their potential for land use and occupation, determine the areas of conflicts in land use and the level of environmental deterioration of the watershed as a whole, to support planning and the consequent reduction of the expansion of desertification. Based on GIS analysis and field work, the environmental parameters that allowed the establishment of the roughness coefficient of each sub-watershed were calculated, following the methodology proposed by Rocha (1997 for the classification of the natural potential use of each watershed. The results showed that four sub-watersheds are suitable for agriculture, three for livestock and reforestation and one for reforestation only. It was also possible to diagnose land use and occupation of each one and to determine land use conflicts. This represented by inappropriate use of soil considering the natural vocation of some sub-watershed, as well as the occurrence of bare soil and mining activities that occur in some sub-watersheds. Thus, from the analysis of conflict in land use, areas to be afforested, availability for or intense use of agricultural lands and the estimate of areas where correct management practices have to be implemented, it was observed that the watershed of Riacho do Tronco has 42.7% of its area in deteriorated stage. Therefore, the high level of environmental deterioration is evident, with consequent risk of desertification. In addition, considering that this area is located in the Brazilian semi-arid region with economic activities practiced without conservation concerns, it is necessary that the government and organized society foster sustainable principles in the economic activities in this watershed.

Full Text Available INTRODUÇÃO: A impedância bioelétrica (BIA tem sido bastante utilizada para o monitoramento da composição corporal em indivíduos de diferentes idades e estados nutricionais. Entretanto, não se sabe qual das equações propostas para crianças e adolescentes é a mais recomendada para utilização em adolescentes com excesso de peso. Objetivo: Verificar a concordância dos métodos de BIA usando três equações diferentes com a absorciometria de raio-X de dupla energia (DXA, para análise da composição corporal de adolescentes com sobrepeso e obesidade.MÉTODOS: Participaram do estudo 27 adolescentes do sexo feminino, com sobrepeso e obesidade. Foram avaliados o percentual de gordura corporal (%GC, a massa gorda (MG e a massa livre de gordura (MLG por DXA e por BIA utilizando as equações propostas por Houtkooper, Schaefer e Deurenberg. ANOVA oneway, gráficos de Bland-Altman e o coeficiente de correlação intraclasse foram utilizados para comparação e verificação da concordância entre os métodos.RESULTADOS: A BIA utilizando a equação proposta por Houtkooper foi a única que não apresentou diferença estatística significativa na estimativa de %GC, MG e MLG em comparação ao DXA e apresentou boa concordância com o DXA na estimativa de %GC (-1,9 ± 3,29%, MG (1,5 ± 2,59 kg e MLG (1,4 ± 2,60 kg, bem como boa reprodutibilidade para %GC (CCI = 0,81, MG (0,96 e MLG (0,89. As equações de Schaefer e de Deurenberg apresentaram menor concordância com o DXA, superestimando a MG e subestimando a MLG e apresentaram reprodutibilidade de moderada a baixa na maioria das medidas da composição corporal.CONCLUSÃO: Quando comparamos as três equações propostas para BIA com o DXA, verificamos que a equação proposta por Houtkooper foi a que melhor concordou com DXA e apresentou boa reprodutibilidade para estimar %GC, MG e MLG em adolescentes com sobrepeso e obesidade.

O delineamento experimental foi o de blocos casualizados com 3 repetições, sendo a parcela constituída de 5 fileiras de 5m de comprimento, espaçados 0,2 m. Avaliou-se a produção de matéria seca de 35 cultivares de alfafa em 29 cortes realizados no período de outubro/1996 a março/1999. O estudo da adaptabilidade e estabilidade das cultivares ao longo dos 29 cortes, foi realizado por meio das metodologias de Eberhart e Russell e Lin e Binns. Verificou-se a existência de interação cultivares x cortes, demonstrando que o comportamento relativo das cultivares não era o mesmo nos diferentes cortes. Das 35 cultivares avaliadas, 14 apresentaram adaptabilidade geral (b1i ou = 1 e boa previsibilidade ( s²di = 0, segundo a metodologia de “Eberhart e Russell”. Das 10 cultivares que apresentaram maior adaptabilidade e estabilidade (menores Pi, segundo a metodologia de Lin e Binns sete também apresentaram adaptabilidade geral e boa previsibilidade segundo a metodologia de Eberhart e Russell. As cultivares SW 8210, Victoria SP, MH 15, 5888, Araucana, BR 1 e BR 3 foram as que apresentaram maior adaptabilidade e estabilidade de comportamento, pelos dois métodos utilizados.

Full Text Available Amostras fecais de coelhos foram examinadas pela técnica de flutuação para a presença e contagem de oocistos do gênero Eimeria, de acordo com a técnica McMaster, em uma investigação com o objetivo de comparar um sistema alternativo não medicamentoso de criação de coelhos e sistemas convencionais com diferentes níveis de controle higiênico. A presença de oocistos nas diferentes explorações foi baixa, mas muito variável. As maiores concentrações de oocistos foram encontradas nas explorações cujas condições higiênicas não foram boas, independentemente do tratamento ou não com anticoccidiano, ou do sistema de criação. Os melhores resultados foram observados no sistema alternativo com boas condições higiênicas. Neste sistema, a concentração de oocistos nos láparos desmamados, que deveriam apresentar máxima susceptibilidade à infecção por Eimeria, foi muito baixa. Estes resultados indicam que o estrito respeito às condições higiênicas é suficiente para o controle da coccidiose e que a profilaxia farmacológica poderia ser evitada sempre que fossem adotadas altas condições higiênicas so sistema criatório ao ar livre, baseado em células subterrâneas exploráveis (tocas.

Calabazas Creek Research, Inc. developed and currently markets Beam Optics Analyzer (BOA) in the United States and abroad. BOA is a 3D, charged particle optics code that solves the electric and magnetic fields with and without the presence of particles. It includes automatic and adaptive meshing to resolve spatial scales ranging from a few millimeters to meters. It is fully integrated with CAD packages, such as SolidWorks, allowing seamless geometry updates. The code includes iterative procedures for optimization, including a fully functional, graphical user interface. Recently, time dependent, particle in cell capability was added, pushing particles synchronically under quasistatic electromagnetic fields to obtain particle bunching under RF conditions. A heat transfer solver was added during this Phase I program. Completed tasks include: (1) Added a 3D finite element heat transfer solver with adaptivity; (2) Determined the accuracy of the linear heat transfer field solver to provide the basis for development of higher order solvers in Phase II; (3) Provided more accurate and smoother power density fields; and (4) Defined the geometry using the same CAD model, while maintaining different meshes, and interfacing the power density field between the particle simulator and heat transfer solvers. These objectives were achieved using modern programming techniques and algorithms. All programming was in C++ and parallelization in OpenMP, utilizing state-of-the-art multi-core technology. Both x86 and x64 versions are supported. The GUI design and implementation used Microsoft Foundation Class.

Full Text Available One hundred seventeen specimens of sharks were caught along the coast of Pernambuco State, Northern Brazil, between May 2004 and May 2007, among which 86 were blacknose sharks, Carcharhinus acronotus, enabling a more detailed study of the species. Blacknose sharks were caught in the 2 study areas along the Boa Viagem/Piedade and Paiva beaches, accounting for the highest relative abundance among the species caught (73.5% of total. Potentially dangerous sharks, tiger and bull sharks, were also caught in the same areas, whereas hammerhead and blacktip sharks were only captured off Boa Viagem/Piedade. Concerning the blacknose shark, the total length (TL ranged from 39.0 to 180.0 cm. Among the 38 females analysed, 32 were juveniles, 11 were maturing, 2 were pre-ovulatory and 21 were pregnant. Sexing was possible for 75 of the 83 embryos, 38 of which were males and 37 were females, with a sex proportion of 1:0.9 and total length ranging between 6.4 and 63.5 cm. Ovarian fecundity ranged from 5 to 10 and uterine fecundity from 1 to 3, with an estimated gestational period of 9 months. Among the 48 males, 6 were juveniles and 42 were adults. Both males and females seem to reach sexual maturity at about 105.0 cm TL. Among the 86 stomachs analysed, only 22.1% had contents, with teleosts as the most frequent item.
