RNA sequence design is studied at least as long as the classical folding problem. Although for the latter the functional fold of an RNA molecule is to be found ,: inverse folding tries to identify RNA sequences that fold into a function-specific target structure. In combination with RNA-based biotechnology and synthetic biology ,: reliable RNA sequence design becomes a crucial step to generate novel biochemical components. In this article ,: the computational tool antaRNA is presented. It is capable of compiling RNA sequences for a given structure that comply in addition with an adjustable full range objective GC-content distribution ,: specific sequence constraints and additional fuzzy structure constraints. antaRNA applies ant colony optimization meta-heuristics and its superior performance is shown on a biological datasets. http://www.bioinf.uni-freiburg.de/Software/antaRNA CONTACT: backofen@informatik.uni-freiburg.de Supplementary data are available at Bioinformatics online. © The Author 2015.

Full Text Available Yannick Fogoum Fogang, Abdoul Aziz Savadogo, Massaman Camara, Dènahin Hinnoutondji Toffa, Anna Basse, Adjaratou Djeynabou Sow, Mouhamadou Mansour Ndiaye Neurology Department, Fann Teaching Hospital, Cheikh Anta Diop University, Dakar, Senegal Abstract: Taenia solium neurocysticercosis (NCC is a major cause of neurological morbidity in the world. Variability in the neuropathology and clinical presentation of NCC often make it difficult to diagnose and manage. Diagnosis of NCC can be challenging especially in endemic and resource-limited countries where laboratory and imaging techniques are often lacking. NCC management can also be challenging as current treatment options are limited and involve symptomatic agents, antiparasitic agents, or surgery. Although antiparasitic treatment probably reduces the number of active lesions and long-term seizure frequency, its efficacy is limited and strategies to improve treatment regimens are warranted. Treatment decisions should be individualized in relation to the type of NCC. Initial measures should focus on symptomatic management, with antiparasitic therapy only to be considered later on, when appropriate. Symptomatic treatment remains the cornerstone in NCC management which should not only focuses on epilepsy, but also on other manifestations that cause considerable burden (recurrent headaches, cognitive decline. Accurate patients' categorization, better antiparasitic regimens, and definition of new clinical outcomes for trials on NCC could improve management quality and prognosis of NCC. Prevention strategies targeting tapeworm carriers and infected pigs are yielding good results in local models. If local elimination of transmission is confirmed and replicated, this will open the door to cysticercosis eradication efforts worldwide.

The Antas reservoir receives the treated effluents which come from acid drainage of uranium ore from the UTM-INB (Ore Treatment Unit - Brazilian Nuclear Industries), located in Caldas, Minas Gerais. This study was conducted in order to determine the possible environmental impact caused by discharge of the treated liquid effluent from the UTM into the Antas reservoir. Biological (ciliated protozoa and Peridinium sp. phytoflagellate) and physicochemical variables (manganese, zinc, sulfate, uranium, dissolved oxygen and temperature), trophic state and saprobity indexes were evaluated. Sampling in reservoir (Cab, P41, P14S, and P14F points) took place during the dry winter season (July 2006). Each day, samples were collected four times (6:00 am, 12:00 pm, 6:00 pm, and 12:00 am). Biological variables analyzed at the Antas reservoir classified it as an oligo trophic and beta-mesosaprobic environment. Chemical parameters indicate failures in the nuclear facility effluent treatment plant, showing that effluents outside of standard limits established by Brazilian current legislation for Class II water are being discharged at point P41. These results agree with biological analyses, since point P41 has the lowest diversity and biomass values for ciliated protozoa organisms, indicating possible environmental impacts on the ecosystem due to effluent discharge by this mining company.(author)

Our aim is to design and edit an e-learning platform characterized by a user interface adapted to the cultural heritage of Senegalese immigrant communities living in Madrid. This project, implemented by the NGO "Casa de Senegal" was developed using a qualitative methodology of participant observation and interviews with teachers and students of this center. As a result it has been developed a map of icons typical of Wolof culture for use in representing the commands in the e-learning platform: e-Senegalaise. Platform created specifically to provide a web environment for contextual learning in a Senegalese immigrant community. As a result it was found that Senegalese immigrants had digital and media skills enough to be able to act autonomously if possessed of a platform for media literacy. However, its competences are limited when try access to basic local news as strategy for his social integration. Local news such as training courses or social grants. A second conclusion is that access to local media plays an essential role for them as a factor of social inclusion as we find a greater integration between those with predominant local information.Este trabajo es resultado de una investigación financiada a través deun proyecto de cooperación PCI de la AECID, entre la Universidad Carlos III deMadrid y la Universidad Cheik Anta Diop.

Ag/ZnO nanostructure for surface enhanced Raman scattering application in the detection of ANTA explosive molecule is demonstrated. A highly rough ZnO microstructure was achieved by rapid thermal annealing of metallic Zn film. Different thickness Ag nanostructures are decorated over these ZnO microstructures by ion beam sputtering technique. Surface enhanced Raman spectroscopic studies carried out over Ag/ZnO substrates have shown three orders higher enhancement compared to bare Ag nanostructure deposited on the same substrate. The reasons behind such huge enhancement are discussed based on the morphology of the sample.

Quartz Crystal Microbalance (QCM was used to investigate the adsorption of the HRP-NHis enzyme (horseradish peroxidase, which was modified by the addition of a tail of six histidine on its extreme N-terminal. The QCM operating at flow of 0.025 mL min-1 on a crystal whose gold electrode was modified with monolayers of SAM-TOA-ANTA-Co2+ and SAM-TOA-ANTA -Co3+. The oxidize form was obtained from the electrochemical oxidation of a monolayer of SAM-TOA-ANTA-Co2+. The results suggest that the HRP-NHis is attached to both monolayers in a similar way; on the contrary, the desortion of the attached protein is dramatically different. Thus, whereas the ligand-Co2+ bonds are reversible, which allows that the anchored protein is easily replaced by imidazol molecules. The 3+ oxidation state of the metal does not allow the interchange of protein by the imidazol molecules.

Full Text Available AIM: This study characterized the water quality of the lotic areas of the Rio das Antas (Antas Riverinfluenced by the construction of the Monte Claro hydroelectric plant (South Brazil, a run-of-the-river reservoir. METHODS: To assess the water quality, we selected four sampling points based on the results obtained in the water-quality monitoring program performed by CERAN (the Rio das Antas Energetic Company in the pre-filling (2002-2004 and post-filling (2005-2008 periods. The river flow was monitored during both of the periods. Seasonal samplings were conducted, and alkalinity, chlorophyll a, total and fecal coliforms, conductivity, color, BOD, COD, total phosphorus, nitrate, nitrite, ammoniacal nitrogen, dissolved oxygen, pH, total dissolved solids, suspended solids, sulfates, temperature and turbidity were evaluated. The results were interpreted according to the Brazilian Environmental Council's Water Quality Index, Trophic State Index and CONAMA Resolution 357/05. To verify the occurrence of alterations before and after the plant operation, t-tests were performed. RESULTS: Significant changes in water quality were not observed after the impoundment. The permanence of the characteristics of the natural hydrography was important for maintaining the water quality. The decline of the water quality in a stretch with reduced flow was caused by Burati stream, a tributary containing high concentrations of nutrients and fecal coliforms. CONCLUSIONS:The Monte Claro hydroelectric plant did not alter the water quality of the Antas River. The small reservoir resulting from the plant project favors the maintenance of the water quality of the river and does not favor eutrophication. Attention should be given to Burati stream, a tributary of the Antas River, regarding its high nutrient and coliform content.OBJETIVOS: Este estudo caracterizou a qualidade da água nos trechos lóticos do rio das Antas influenciados pela construção da usina hidrel

Full Text Available A bacia hidrográfica do ribeirão Água das Antas localiza-se no centro norte do estado do Paraná, tendo seu maior domínio do município de Grandes Rios, na transição do Segundo para o Terceiro Planalto Paranaense. Está modelada sobre as litoestruturas das Formações Rio do Rasto, Pirambóia, Botucatu e Serra Geral da Bacia Sedimentar do Paraná. No presente artigo são identificadas e interpretadas as anomalias de drenagem na referida bacia, a partir da aplicação de índices morfométricos e de técnicas de sensoriamento remoto e geoprocessamento para a confecção de anomalias da área de estudo. As anomalias de drenagem correspondem a anormalidades ou irregularidades decorrentes principalmente de processos morfoestruturais e morfotectônicos. Os índices morfométricos utilizados, como fator de assimetria da bacia, fator de simetria topográfico transversal e relação declividade-extensão, apresentaram dados satisfatórios, com a identificação de alto índice de assimetrias na bacia. Por meio da fotointerpretação foram identificados curvaturas anômalas, segmentos retilíneos, erosões ativas, zona de abandono de drenagem, drenagens radiais e sub-radiais e tendência de migração do canal, as quais são consideradas anomalias. Devido à forte assimetria do canal, a bacia do ribeirão Água das Antas foi analisada à luz de zonas morfoestruturais, geradas pelo desnivelamento de blocos de falhas, sendo possível verificar a atuação da tectônica recente que afetou a rede de drenagem.

However, tension governs the relationship between Shaka and his half-brother. This rivalry resulted in the murder of Shaka. This fratricide, source of tragedy precipitates Latyr in the mud of the history. He is cursed for his ignoble act.

Full Text Available “African thinking,” “African thought,” and “African philosophy.” These phrases are often used indiscriminately to refer to intellectual activities in and/or about Africa. This large field, which sits at the crossroads between analytic philosophy, continental thought, political philosophy and even linguistics is apparently limitless in its ability to submit the object “Africa” to a multiplicity of disciplinary approaches. This absence of limits has far-reaching historical origins. Indeed it needs to be understood as a legacy of the period leading to African independence and to the context in which African philosophy emerged not so much as a discipline as a point of departure to think colonial strictures and the constraints of colonial modes of thinking. That the first (self-appointed exponents of African philosophy were Westerners speaks volumes. Placide Tempels but also some of his predecessors such as Paul Radin (Primitive Man as Philosopher, 1927 and Vernon Brelsford (Primitive Philosophy, 1935 were the first scholars to envisage this extension of philosophy into the realm of the African “primitive.” The material explored in this article – Statues Also Die (Marker, Resnais, and Cloquet, Bantu Philosophy (Tempels, The Cultural Unity of Negro Africa (Cheikh Anta Diop, and It For Others (Duncan Campbell - resonates with this initial gesture but also with the ambition on part of African philosophers such as VY Mudimbe to challenge the limits of a discipline shaped by late colonialism and then subsequently recaptured by ethnophilosophers. Statues Also Die is thus used here as a text to appraise the limitations of African philosophy at an early stage.  The term “stage,” however, is purely arbitrary and the work of African philosophers has since the 1950s often been absorbed by an effort to retrieve African philosophizing practices before, or away from, the colonial matrix. This activity has gained momentum and has been

Knowledge about hydrological and sedimentological dynamics of a river basin is fundamental to the adequate management of water resources, and it can support the identification of contaminants in the water, the estimation of water erosion, the estimation of reservoir siltation, and even the reduction of water treatment costs.

Knowledge about hydrological and sedimentological dynamics of a river basin is fundamental to the adequate management of water resources, and it can support the identification of contaminants in the water, the estimation of water erosion, the estimation of reservoir siltation, and even the reduction of water treatment costs. The study carried out in Alto Ribeirão das Antas River Basin assessed, throughout seasons, all interactions between the surface runoff and the transport of suspended and underwater hydro-sediments, through direct monitoring of two sites at the Ribeirão das Antas channel.

Diversity vs. Difference: A Critical Analysis of Hybridity and Cultural Identity Crisis in the Novels of Cheikh Hamidou Kane and Chinua Achebe

Directory of Open Access Journals (Sweden)

Alassane Abdoulaye DIA

2014-03-01

Full Text Available Hybridity has been one of the most recurrent themes of the African fiction during and after the colonial period. It is one of the complex issues of postcolonial Africa as it was difficult for many Négritude writers, such as Léopold Sédar Senghor, Aimé Césaire, and Frantz Fanon, to find a common ground on what colonization bequeathed to Africa. Hence, Senghor (1977 came up with the oxymoron of “colonization as a necessary evil”. However, to evaluate the advantages and disadvantages of colonization to Africans, in terms of impact, one should go further than expected to approve or dismantle Senghor’s position. The issues of cultural hybridity and identity crisis are still topical in African literature. Also, in the context of globalization, it is relevant to study the post-independence situation of African societies as represented by their early prominent and visionary writers such as Chinua Achebe from Nigeria and Cheikh Hamidou Kane from Senegal. Therefore, hybridity becomes a concern, through which writers address the dilemma of the African. They portray the intellectual who is entrapped in two different cultures and becomes alienated. The corpus of this article showcases this phenomenon through the characters of Obi Okonkwo in No Longer at Ease (1960 and Samba Diallo in Ambiguous Adventure (1962. Through a critical analysis and a post-colonial perspective, the article focuses on identity crisis, alongside the contentious debate over cultural diversity versus cultural difference, which is highly reflected in the novels investigated in the paper.

Full Text Available A project to restore a degraded area must firstly reestablish organic soil matter and nutrient cycling process. In order to evaluate the influence of indigenous tree plantations on changings in soil fertility and organic matter dynamics, an experiment was installed at the Poço das Antas Biological Reserve, an Atlantic Rain Forest remnant of ca. 5,200. Six treatments involved mature forests (F, 8-year-old mixed plantations of indigenous tree species (P, and abandoned pastures (G, at both the flooding (V and the sloping (M areas of the Reserve. The experimental design was completely randomized. Soil samples were collected at the layers 0-2.5cm; 2-5-7.5cm; and 7.5-20cm to evaluate soil pH, and Al, Ca+Mg, P, K, C and N contents. The PV treatment showed higher values for the exchangeable cátions, C and soil organic matter (SOM contents, indicating high cycling rates and biological activity. Soil stability was considered to be high in all treatments, since C:N ratio was lower than 12:1. Organic matter fragmentation showed a higher amount of fulvic acids (FA, humic acids (HA and humin (HU in the PV treatment, for the three soil layers. The plantation on the sloping areas (PM showed the highest values of (FA+HA/HU ratio, suggesting a lower stability condition. Results suggest indigenous tree plantations have great potential to restore nutrient cycling and soil organic matter contents in short term period in areas where forests have been converted into pastures. Techniques to accelerate the development of trees plantation on the sloping areas must be adopted.

Food intake is controlled by peripheral signals from the gastrointestinal tract and adipocytes, which are integrated within the central nervous system. There is evidence that signals from the GI tract are modulated by long term changes in diet, possibly leading to hyperphagia and increased body weight. We tested the hypothesis that diet-induced obese-prone (DIO-P) and obese-resistant (DIO-R) mice strains differ in the long term adaptive response of the gut-brain pathway to a high fat diet. Immunochemical detection of Fos protein was used as a measure of neuronal activation in the nucleus of the solitary tract (NTS) in response to intragastric administration of lipid in DIO-P (C57Bl6) and DIO-R (129sv) mouse strains maintained on chow or high fat, high energy diets (45% or 60% kcal from fat). Intragastric lipid administration activated neurons in the NTS in both DIO-P and DIO-R mice; the number of activated neurons was significantly greater in DIO-P than in DIO-R mice (Pdiet, for 4 or 8 weeks, compared to chow fed controls (Pdiet (45% or 60%) had no effect on lipid-induced activation of NTS neurons. These results demonstrate that DIO-P and DIO-R mice strains differ in the adaptation of the pathway to long term ingestion of high fat diets, which may contribute to decrease satiation and increased food intake.

Tempo e Espaço Guarani: um estudo acerca da ocupação, cronologia e dinâmica de movimentação pré-colonial na Bacia do Rio Taquari/Antas, Rio Grande do Sul, Brasil

Fernanda Schneider

Full Text Available Resumo Neste artigo foram analisadas as relações espaciais e temporais da ocupação Guarani pré-colonial na Bacia do Rio Taquari/Antas a partir da delimitação do perímetro da ocupação e seu estabelecimento na paisagem, da cronologia intrasítio e regional e de discussões referentes às movimentações espaciais. A partir dos resultados foram mapeados 121 sítios Guarani na porção centro-sul da Bacia, em um perímetro de várzeas que circundou as terras altas do Planalto das Araucárias, demonstrando tratar-se de uma ocupação regional longa, entre os séculos XIV e XVIII. O estabelecimento teria ocorrido a partir da conexão entre o Rio Jacuí e o Rio Taquari/Antas, em uma expansão compulsória do sul para o norte, observando-se assentamentos contemporâneos em todo o perímetro e sítios com fatores de alta permanência. Tal dinâmica justificar-se-ia a partir de um controle consciente do ambiente, permitindo, por um lado, a manutenção das aldeias, e, por outro, o crescimento demográfico e novas expansões. Além da motivação demográfica, inferiu-se a possibilidade de que os limites da ocupação Guarani na região tenham sido estabelecidos de forma igualmente consciente a partir de um pulso de expansão inicial e posterior estabilidade, configurando-se a ocupação compulsória como uma estratégia de manutenção política do território.

Habitus of social security in the lifestyles of rural families: the case of the São Miguel do Anta and Piranga municipalities in Zona da Mata Mineira, Brazil

Vanessa Aparecida Moreira de Barros

Full Text Available ABSTRACT: The universalization of the right to social security for rural producers and rural workers is a recent victory for Brazilian society. The implementation of this benefit began in the early 1990s. This article aimed to analyze the effects of rural social security on the lifestyle of families with retirees. The research was conducted in two small municipalities with agricultural economies from Zona da Mata Mineira region. The research used cross-sectional data collection procedures by applying a survey with open and closed-ended questions about consumption and living. The research sample was representative of the study population, comprising 117 rural elderly people, 64 from Piranga City and 53 from São Miguel do Anta City. Data obtained were categorized, analyzed and tested using Statistical Package for Social Sciences (SPSS software. The survey results highlighted routine behavior and a predisposition to act based on a long term planning system, supported by the certainty of receiving the pension. Planned and long-term investments became a reality, including home improvement projects and acquisition of durable goods. Concerns about immediate family maintenance gave way to a perspective based on future planning.

Full Text Available Since the last major international coffee crisis, in the 1990s, the production of specialty coffee has been considered one of the main market alternatives for small farmers. However, the increase in world consumption of this type of coffee has also attracted the attention of major exporters, roasters and retailers, with consequent standardization of production. On the one hand, the entry in such markets has important benefits for small producers, particularly in countries recognized by the production of lower quality coffee and insufficient collective organization of farmers, as the Brazilian case, on the other hand, external regulation and the role of large companies have extended the differences of power and distribution of value along the productive spacial circuit. Therefore, this article aim to examine the paradox resulting from the insertion of small producers of the Associação dos Agricultores familiares do Córrego D’Antas, Poços de Caldas (MG, in the Fairtrade market. For this, starts the debate on globalization and standardization of specialty coffee production. Then deepens the analysis in Fairtrade and finally, it highlight the benefits and challenges faced by Assodantas.

Plant extractivism in light of game theory: a case study in northeastern Brazil.

Science.gov (United States)

Silva, Rafael Rv; Gomes, Laura Jane; Albuquerque, Ulysses Paulino

2015-02-23

Game theory enables the predictive study of the behavior of agents that recognize the mutual interdependence of their decisions and act rationally and strategically to maximize their own gains. In this paper, the extractivism of pequi (Caryocar coriaceum Wittm.) and fava d'anta (Dimorphandra gardneriana Tul.) in an area of common use of the semiarid region of northeastern Brazil is described as a model to illustrate a practical application of game theory in the interpretation of the phenomena analyzed in ethnobiological research. Field research was conducted in the Araripe-Apodi National Forest. Semi-structured interviews were conducted with 55 informants recognized as knowledgeable and experienced in the extractivism of pequi and fava d'anta in the region. In the interviews, information that could contribute to the identification and understanding of the focal points of extractivism in the region was surveyed. Data were analyzed under an analytical/descriptive approach using the "content analysis" technique. There was a logic of competitive entrepreneurship around the commercial extractivism of pequi and fava d'anta in the region. Among the extractivists of pequi, one of the main collection rules refers to the prohibition of removing immature fruits by using sticks or shaking the branches. In the extractivism of fava d'anta, no specific rules have been established by collectors, but there is a predominant behavior of withdrawing all available fruits (pods) on a tree in a single visit. In an analysis guided by game theory, the collection decisions adopted by extractivists to maximize gain from the activity can be considered justifiable from the standpoint of economic rationality. The "game of extractivism" of pequi and fava d'anta operates under conditions similar to the "tragedy of the commons." In this game, the non-cooperative solution is converted to the Nash equilibrium. The approach used in this study contributed to the identification of strategies and

Full Text Available A baixa densidade espacial da rede hidrométrica nacional tem resultado em grandes limitações para a representação do comportamento dos recursos hídricos. Dessa forma, a regionalização de vazões é uma alternativa para melhor explorar os dados já existentes, transferindo informações de um local para outro dentro de uma área com comportamento hidrológico semelhante. Nesse sentido, o objetivo deste trabalho foi avaliar as estimativas da vazão mínima de permanência Q95 obtidas através dos métodos Tradicional e Conservação de Massas na bacia do Rio Taquari-Antas, pertencente ao Estado do Rio Grande do Sul, visando auxiliar o planejamento dos recursos hídricos, além de facilitar as tomadas de decisão em relação aos processos de outorga do direito de uso das águas. Como variável explicativa para a regressão matemática foi utilizada a área de drenagem proveniente do Modelo Digital de Elevação Hidrograficamente Condicionado (MDEHC. Foram obtidas as equações de regionalização da vazão de referência Q95 e as respectivas regiões hidrologicamente homogêneas para os dois métodos testados, sendo a magnitude dos erros relativos inerente às metodologias empregadas. Consideradas as particularidades deste trabalho, ambos os métodos avaliados apresentaram resultados satisfatórios na obtenção de modelos para estimativa da vazão Q95, entretanto destaca-se que as técnicas aplicadas não substituem as informações hidrológicas obtidas com uma rede hidrométrica suficientemente densa.

Full Text Available Benthic macroinvertebrate in four rivers, three in the Pelotas River basin (Divisa, Marco and Silveira rivers, in the headwaters of the Uruguai River and one in the Taquari-Antas system (Antas River, a tributary in the Guaíba basin, in the state of Rio Grande do Sul, were identified. Two samples were collected in summer, autumn and spring, with one replicate in each river. The total of 28,961 specimens included members of Platyhelminthes, Annelida, Acarina, Insecta, Crustacea and Mollusca. The Silveira and Marco rivers showed significant differences in the indices of Shannon-Weaver (H’, Simpson’s Reciprocal (1/D, Margalef (DMg and Equitability (E. The Silveira River showed the highest means of diversity and the EPT index (Ephemeroptera, Plecoptera, Trichoptera. Comparison among the diversity indices, considered individually, were insufficient to show differences in community structure, for the purpose of ecological characterization of the rivers. The EPT values characterized the Divisa River as having the highest abundance (73%, followed by the Marco (71%, Antas (48% and Silveira (36%. These results suggest that the Silveira River is subject to moderate environmental stress, from human impact, although it showed the highest diversity of the major macrobenthic groups.Os macro-invertebrados bentônicos que ocorrem em quatro rios, três pertencentes à bacia do Rio Pelotas (Rios Divisa, Marco e Silveira nas cabeceiras do Rio Uruguai e um ao sistema Taquari-Antas (Rio Antas, tributário da bacia do Guaíba, no Estado do Rio Grande do Sul, foram identificados.

Strategic use of oral toxicants could allow for practical and sustainable control schemes for the invasive common carp (Cyprinus carpio, or ‘carp’) if a toxicant selectively targeted carp and not native species. In this study, we incorporated antimycin-a (ANT-A), a known fish toxicant, into a corn-based bait and conducted a series of experiments to determine its toxicity, leaching rate, and species-specificity. Our results showed that ANT-A was lethal to carp at doses ≥ 4 mg/kg and that the amount of ANT-A that leached out of the bait in 72 h was not lethal to carp or bluegill (Lepomis macrochirus). Species-specificity trials were conducted in 227 L tanks, in which carp were stocked with three native species representing families that occur sympatrically with carp in our study region: the fathead minnow (Pimephales promelas), yellow perch (Perca flavescens) and bluegill. These trials showed high mortality of carp (46%) and fathead minnows (76%) but no significant mortality of perch or bluegill. Finally, a pond study, which used the same species composition except for fathead minnows, resulted in 37% morality among adult carp and no mortality among perch or bluegill. Our results suggest that corn-based bait that contains ANT-A could be used to selectively control carp in ecosystems dominated by percids or centrarchids, such as lakes across the Great Plains ecoregion of North America, where carp are especially problematic.

A highly efficient rhodium-catalyzed chemo- and regioselective addition of β-ketoacids to alkynes is reported. Applying a Rh(i)/(S,S)-DIOP catalyst system, γ,δ-unsaturated ketones were prepared with exclusively branched selectivity under mild conditions. This demonstrates that readily available alkynes can be an alternative entry to allyl electrophiles in transition-metal catalyzed allylic alkylation reactions.

Determination of antimycin-A in water by liquid chromatographic/mass spectrometry: single-laboratory validation.

Science.gov (United States)

Bernardy, Jeffry A; Hubert, Terrance D; Ogorek, Jacob M; Schmidt, Larry J

2013-01-01

An LC/MS method was developed and validated for the quantitative determination and confirmation of antimycin-A (ANT-A) in water from lakes or streams. Three different water sample volumes (25, 50, and 250 mL) were evaluated. ANT-A was stabilized in the field by immediately extracting it from water into anhydrous acetone using SPE. The stabilized concentrated samples were then transported to a laboratory and analyzed by LC/MS using negative electrospray ionization. The method was determined to have adequate accuracy (78 to 113% recovery), precision (0.77 to 7.5% RSD with samples > or = 500 ng/L and 4.8 to 17% RSD with samples < or = 100 ng/L), linearity, and robustness over an LOQ range from 8 to 51 600 ng/L.

Automorphisms of Algebras and Bochner's Property for Vector Orthogonal Polynomials

Science.gov (United States)

Horozov, Emil

2016-05-01

We construct new families of vector orthogonal polynomials that have the property to be eigenfunctions of some differential operator. They are extensions of the Hermite and Laguerre polynomial systems. A third family, whose first member has been found by Y. Ben Cheikh and K. Douak is also constructed. The ideas behind our approach lie in the studies of bispectral operators. We exploit automorphisms of associative algebras which transform elementary vector orthogonal polynomial systems which are eigenfunctions of a differential operator into other systems of this type.

Chirality in distorted square planar Pd(O,N)2 compounds.

Science.gov (United States)

Brunner, Henri; Bodensteiner, Michael; Tsuno, Takashi

2013-10-01

Salicylidenimine palladium(II) complexes trans-Pd(O,N)2 adopt step and bowl arrangements. A stereochemical analysis subdivides 52 compounds into 41 step and 11 bowl types. Step complexes with chiral N-substituents and all the bowl complexes induce chiral distortions in the square planar system, resulting in Δ/Λ configuration of the Pd(O,N)2 unit. In complexes with enantiomerically pure N-substituents ligand chirality entails a specific square chirality and only one diastereomer assembles in the lattice. Dimeric Pd(O,N)2 complexes with bridging N-substituents in trans-arrangement are inherently chiral. For dimers different chirality patterns for the Pd(O,N)2 square are observed. The crystals contain racemates of enantiomers. In complex two independent molecules form a tight pair. The (RC) configuration of the ligand induces the same Δ chirality in the Pd(O,N)2 units of both molecules with varying square chirality due to the different crystallographic location of the independent molecules. In complexes and atrop isomerism induces specific configurations in the Pd(O,N)2 bowl systems. The square chirality is largest for complex [(Diop)Rh(PPh3 )Cl)], a catalyst for enantioselective hydrogenation. In the lattice of two diastereomers with the same (RC ,RC) configuration in the ligand Diop but opposite Δ and Λ square configurations co-crystallize, a rare phenomenon in stereochemistry. © 2013 Wiley Periodicals, Inc.

Treated effluents from uranium mine with acid mine drainage can impact receiving water bodies. AMD is relevant from the environmental view due to the large volume of effluents generated, known to affect aquatic biota. Studies show that one of the main problems of treated effluents released by UTM/INB on the catchment basin of Ribeirao das Antas is associated to high Mn values in water samples. In this context, acute 48-h toxicity tests with Mn were conducted with Ceriodaphnia silvestrii and Daphnia magna to determine the No Observed Effect Concentration (NOEC) and the Observed Effect Concentration (OEC) in laboratory bioassays and to verify the potential toxicity of the Mn in face of concentrations found in water samples from the Antas Dam, which receives treated effluents from UTM/INB. In this study, preliminary results of acute toxicity for C. silvestrii indicated OEC values between 9.0 and 10.0 mg Mn/L and NOEC < 3.0 mg Mn/L. For D. magna, OEC and NOEC concentrations were ≥ 30 mg Mn/L and ≤ 80 mg Mn/L, respectively. It was verified that Mn concentrations determined in environmental samples registered the highest value at 1.75 mg Mn/L, below the OEC concentrations recorded for both species. Since manganese occurs in the composition of the effluent that may contain other stable and radioactive elements, complementary ecotoxicological tests must be conducted, aiming at the assessment of synergistic and antagonistic effects of the chemical mixture that makes up the radioactive effluents that are treated and released at the Antas Dam. Such bioassays are underway in the Radioecology Laboratory at LAPOC/CNEN. (author)

The quality of the water in a uranium-ore-mining area located in Caldas (Minas Gerais State, Brazil) and in a reservoir (Antas reservoir) that receives the neutralized acid solution leaching from the waste heaps generated by uranium mining was investigated. The samples were collected during four periods (October 2008, January, April and July 2009) from six sampling stations. Physical and chemical analyses were performed on the water samples, and the data obtained were compared with those of the Brazilian Environmental Standards and WHO standard. The water samples obtained from waste rock piles showed high uranium concentrations (5.62 mg L(-1)), high manganese values (75 mg L(-1)) and low average pH values (3.4). The evaluation of the water quality at the point considered the limit between the Ore Treatment Unit of the Brazilian Nuclear Industries and the environment (Consulta Creek) indicated contamination by fluoride, manganese, uranium and zinc. The Antas reservoir showed seasonal variations in water quality, with mean concentrations for fluoride (0.50 mg L(-1)), sulfate (16 mg L(-1)) and hardness (20 mg L(-1)) which were low in January, evidencing the effect of rainwater flowing into the system. The concentrations for fluoride, sulfate and manganese were close or above to the limits established by current legislation at the point where the treated mining effluent was discharged and downstream from this point. This study demonstrated that the effluent discharged by the UTM affected the quality of the water in the Antas reservoir, and thus the treatments currently used for effluent need to be reviewed.

Four cores, collected during the 1995/96 Italian Antarctic cruise and located north and south of the Polar Front, provided both qualitative and quantitative information about changes of the sediment settings driven by climate changes. Biogenic silica and organic carbon flux variations and sedimentological analyses allow us to make inferences about the fluctuation of the Polar Front during the last climate cycles: the records of our cores Anta96-1 and Anta96-16 account for fluctuations of the Polar Front of at least 5 degrees with respect to the present position, with a concomitant movement of the Marginal Ice Zone. The very low accumulation rates at the study sites are probably due to the scarce availability of micronutrients. In the area south of the Polar Front, sediment accumulation, after a decrease, appears constant during the last 250,000 yr. A subdivision in glacial/interglacial stages has been proposed, which permits the identification of the warm stage 11, which is particularly important in the Southern Ocean.

Enhanced protein loading on a planar Si(111)-H surface with second generation NTA

Science.gov (United States)

Liu, Xiang; Han, Huan-Mei; Liu, Hong-Bo; Xiao, Shou-jun

2010-08-01

A Si(111)-H surface was modified via a direct reaction between Si-H and 1-undecylenic acid (UA) under microwave irradiation to form molecular monolayers with terminal carboxyl groups. After esterifying carboxylic acid being esterified with N-hydroxysuccinimide (NHS), aminobutyl nitrilotriacetic acid (ANTA) was bound to the silicon surface through amidation (pH = 8.0) between its primary amino group and NHS-ester, producing nitrilotriacetic acid (NTA) anions. Then hexa-histidine tagged thioredoxin-urodilatin (his-tagged protein) and FITC-labeled hexa-histidine tagged thioredoxin-urodilatin (FITC-his-tagged protein) can be anchored after NTA was coordinated with Ni 2+. Furthermore, the NTA-terminated chip was acidified with 0.1 M HCl and subsequently esterified with NHS and then amidated with ANTA again to produce a second generation NTA. Thus the surface density of nitrilotriacetic acid anions was improved and resultantly that of anchored proteins was also enhanced through the iterative reactions. Both multiple transmission-reflection infrared spectroscopy (MTR-IR) and fluorescence scanning measurements demonstrated a proximate 1.63 times of anchored proteins on the second generation NTA/Ni 2+ as that on the first generation NTA/Ni 2+ monolayer.

Writing Double: Politics and The African Narrative of French Expression

Directory of Open Access Journals (Sweden)

John D. Erickson

1991-01-01

Full Text Available This essay studies two African narratives of French expression ( Le Temps de Tamango of Boubacar Diop and L'Enfant de sable of Tahar ben Jelloun to see how they create a discourse of difference that challenges and deconstructs the conventions of the discursive system of French, its signifying practices, and its ideological underpinnings. The tactics of these narratives, which mark them as post-colonial in a strict sense (as opposed to neo-colonial, are productive of a radical other-meaning, a new meaning that "speaks" to the concerns of and problems confronting the non-Western writer.

A 500-year history of floods in the semi arid basins of south-eastern Spain

Science.gov (United States)

Sánchez García, Carlos; Schulte, Lothar; Peña, Juan Carlos; Carvalho, Filpe; Brembilla, Carla

2016-04-01

Floods are one of the natural hazards with higher incidence in the south-eastern Spain, the driest region in Europe, causing fatalities, damage of infrastructure and economic losses. Flash-floods in semi arid environments are related to intensive rainfall which can last from few hours to days. These floods are violent and destructive because of their high discharges, sediment transport and aggradation processes in the flood plain. Also during historical times floods affected the population in the south-eastern Spain causing sever damage or in some cases the complete destruction of towns. Our studies focus on the flood reconstruction from historical sources of the Almanzora, Aguas and Antas river basins, which have a surface between 260-2600 km2. We have also compiled information from the Andarax river and compared the flood series with the Guadalentín and Segura basins from previous studies (Benito et. al., 2010 y Machado et al., 2011). Flood intensities have been classified in four levels according to the type of damage: 1) ordinary floods that only affect agriculture plots; 2) extraordinary floods which produce some damage to buildings and hydraulic infrastructure; 3) catastrophic floods which caused sever damage, fatalities and partial or complete destruction of towns. A higher damage intensity of +1 magnitude was assigned when the event is recorded from more than one major sub-basin (stretches and tributaries such as Huércal-Overa basin) or catchment (e.g. Antas River). In total 102 incidences of damages and 89 floods were reconstructed in the Almanzora (2.611 km2), Aguas (539 km2), Antas (261 km2) and Andarax (2.100 km2) catchments. The Almanzora River was affected by 36 floods (1550-2012). The highest events for the Almanzora River were in 1580, 1879, 1973 and 2012 producing many fatalities and destruction of several towns. In addition, we identified four flood-clusters 1750-1780, 1870-1900, 1960-1977 and 1989-2012 which coincides with the periods of

Le piège : Kabyle de langue, Arabe de religion

2011-10-01

Full Text Available Starting from a written exchange between a Kabyle village imam and Cheikh Hamani that deals with the issue of using the Berber language in religious sermons, this paper analyzes the main transformations that have had an impact on the Kabyle religious field (and more broadly the Algerian one: the status of the imam, the renovation of the mosques and the development of the Friday sermon. The Berber movement is, more often than not, represented as a secular movement based on linguistic and cultural claims. But the Kabyle society went through an intense period of arabization and strengthening of its religious aspiration. In view of these changes, the question of the impact and objectives of translations of the Koran in Berber are raised.

Structures and lithofacies of inferred silicic conduits in the Paraná-Etendeka LIP, southernmost Brazil

Science.gov (United States)

Simões, M. S.; Lima, E. F.; Sommer, C. A.; Rossetti, L. M. M.

2018-04-01

Extensive silicic units in the Paraná-Etendeka LIP have been long interpreted as pyroclastic density currents (rheomorphic ignimbrites) derived from the Messum Complex in Namibia. In recent literature, however, they have been characterized as effusive lava flows and domes. In this paper we describe structures and lithofacies related to postulated silicic lava feeder conduits at Mato Perso, São Marcos and Jaquirana-Cambará do Sul areas in southern Brazil. Inferred conduits are at least 15-25 m in width and the lithofacies include variably vesicular monomictic welded and non-welded breccias in the margins to poorly vesicular, banded, spherulitic and microfractured vitrophyres in the central parts. Flat-lying coherent vitrophyres and massive obsidian are considered to be the subaerial equivalents of the conduits. Large-scale, regional tectonic structures in southern Brazil include the NE-SW aligned Porto Alegre Suture, Leão and Açotea faults besides the Antas Lineament, a curved tectonic feature accompanying the bed of Antas river. South of the Antas Lineament smaller-scale, NW-SE lineaments limit the exposure areas of the inferred conduits. NE-SW and subordinate NW-SE structures within this smaller-scale lineaments are represented by the main postulated conduit outcrops and are parallel to the dominant sub-vertical banding in the widespread banded vitrophyre lithofacies. Upper lava flows display flat-lying foliation, pipe-like and spherical vesicles and have better developed microlites. Petrographic characteristics of the silicic vitrophyres indicate that crystal-poor magmas underwent distinct cooling paths for each inferred conduit area. The vitrophyre chemical composition is defined by the evolution of trachydacitic/dacitic vitrophyres with 62-65 wt% SiO2 to rhyodacite and rhyolite with 66-68 wt% SiO2. The more evolved rocks are assigned to the latest intrusive grey vitrophyre outcropping in the center of the conduits. Degassing pathways formed during

Ecotoxicological evaluation of water of the hydrographic Basin of the Una River using the bioindicator Ceriodaphnia dubia

Directory of Open Access Journals (Sweden)

Tatiane Alves

2013-12-01

Full Text Available The majority of the Una River Basin is located in Taubaté County and contributes significantly to its water supply. The main goal of this research was to evaluate the water quality of the Una River using the microcrustacean C. dubia as bioindicator for tests of chronic and acute toxicity. Bimonthly water samples were obtained from each of six localities throughout the Una Basin, from March to October, 2011. Physical-chemical water parameters such as pH, electrical conductivity, hardness, dissolved oxygen and precipitation were measured and correlated to the C. dubia reproductive rates. No significant relationships were found between the water’s electrical conductivity and precipitation with respect to bioindicator reproductive rates. However, at the Sete Voltas, Antas and Rocinha Sub-Basins, significant interactions were detected between some water parameters and reproductive rates, suggesting that water may constrain the reproduction of C. dubia. Acute toxicity was not detected in any of the six sites, while chronic toxicity was recorded at Rocinha, Sete Voltas, Antas, Médio and Baixo Una Sub-Basins. In general, the water quality of the Una Basin, as indicated by the absence of acute toxicity, still remains in an acceptable conservation condition. Caution is needed, however, since slight pollution sources are causing chronic toxicity in some localities. In addition, as the microcrustacean C. dubia, appeared to be a reliable bioindicator in this investigation, we suggest that it be used for continuous water quality monitoring programs.

Historical assessment of uranium release by the ore treatment unit - at Caldas, Minas Gerais, Brazil from 1999 to 2011

The Ore Treatment Unit (OTU) is located at the source of three rivers: Ribeirao das Antas, Ribeirao do Soberbo and Corrego da Consulta. Each interface of installation with the environment, at the tree rivers, has been monitored for the release of radionuclides. At Ribeirao das Antas a weekly sample collection was made at point 014. At Ribeirao Soberbo there was a weekly sample collection at point 025, and at Corrego da Consulta a monthly collection was carried out at point 076. This work analyses the average annual releases of uranium from the historical series started in 1999 and ended in 2011. Points 014 and 025 showed average release of 0.12 Bq L -1 . Point 076 showed somewhat higher average release, 1.27 Bq L -1 . An Analysis Of Variance test (ANOVA) has been carried out to verify the existence of different means between these collecting points. The averages were considered statistically different. As a complementary analysis, the Student's t test was performed between the averages at considered points. Between points 014 and 025, the averages were considered identical. Between points 014 and 076, the average release at point 076 was considered higher than that at point 014. The same behavior was observed between points 025 and 076. The releases at point 076 were considered higher than those at point 025. Thus it can be concluded that releases at points 014 and 025 are identical and both are lower than releases at point 076. (author)

The fundamental condition for the bioleaching of the uranium ore is the presence of metallic sulfide such as pyrite associated with the ore, which is found in the ore and in the waste at the Unidade de Tratamento de Minerio (UTM) of Pocos de Caldas, State of Minas Gerais, Brazil. The present study aims to determine the chemical and microbiological characteristics in effluents of uranium mining from the UTM and in Antas dam, which receives treated effluents from the UTM. Water samples were collected Pit Mine (CM), located within the UTM facilities and from site 41 (Antas dam) in July and October 2008. We verified low pH values in water samples from CM (3.7) in comparison to the ones found at site 41 (6.65). There was a higher medium density value of Acidithiobacillus ferrooxidans, Acidithiobacillus thiooxidans and heterotrophic acidophilic bacteria in water samples at site CM compared to the values recorded from samples at site 41. Medium values of Fe 2+ , uranium and zinc in samples from the site CM were higher than at site 41. The concentration of fluoride (68.5 mL -l ) and manganese (2.34 mL -1 ) in water samples from site 41 were above the limits fixed for water bodies in Resolution CONAMA 357. The relative seasonal variation of some variables observed at site CM (low pH values, high densities of Acidithiobacillus sp. and heterotrophic acidophilic bacteria) shows that this site is one of the main sites of occurrence of acid mine drainage and action of bioleaching bacteria at UTM.

Bortolan reservoir (BR), part of the Ribeirao das Antas Hydrographic Sub-Basin, is a dam located in the Pocos de Caldas Plateau region and characterized by the reception of industrial and domestic residue discharge from the city of Pocos de Caldas. Another important dam, found within the same hydrographic sub-basin and the focus of many studies as well, is Antas reservoir (AR), situated on the proximities of a uranium mine (Brazilian Nuclear Industries Ore Treatment Unit - UTM/INB), and the receiver of treated radioactive effluents originated there. The UTM/INB Pit Mine (PM) is an artificial pond characterized by its acidity and elevated electrical conductivity, besides the presence of radioactive and stable metals. The focus of this study is to determine the phylogenetic classification of the Bacteria and Archaea domains, in addition to quantify the bacterial community at points PM, BR and AR, seeking to compare the data to results from other analyzed water bodies. These microorganisms can be determined with the use of molecular techniques that allow their phylogenetic identification, such as the Fluorescent in situ Hybridization (FISH) that detects the presence of specific organisms' DNA or RNA. In the FISH method, probes produced from each domain's DNA fragments are used (EUB338 and ARC915), allowing the identification of oligonucleotide sequences with a higher degree of similarity. The bacterial cells quantification is verified by the use of the DAPI (4-6-diamidino-2-phenylindole) stain, allowing the density calculation of the bacteria found in the samples from AR and BR, as well as from the PM.

The Ore Treatment Unit consists of an open cast mine (CM), its mining waste areas, facilities for the physical treatment of the ore, and a chemical treatment plant for uranium extraction. At CM, the processes of acid drainage create effluents, which are treated by chemical processes and, thereafter, disposed of in Antas dam. The objective of the present study was to make an inventory of zooplanktonic and describe the physicochemical characteristics of site CM and at the site of treated effluents disposal (site 41), located at Antas dam. Water samples were collected in October/08 and January/09, in order to describe the abiotic variables and the zooplankton community. The average values of conductivity at sites CM and 41 were 2415 and 422 μ/cm 2 , respectively. Values of pH at site CM remained acid, whereas, at site 41 we recorded values near neutrality. The concentrations of total nutrients at both sampling sites were higher in the rainy season. Zooplankton species richness present at site CM was lower than at site 41, and there were only two identified species Bosmina sp and Keratella americana. At site 41 we recorded more species, mainly of the Rotifera. Among Cladocera, we identified two species, regarding Copepoda, the orders Cyclopoida and Calanoida were present. At site CM the density values were lower compared to site 41. The preliminary assessment of the zooplankton community showed lower values of species richness and density at site CM, what may be probably explained by the adverse environmental conditions for zooplankton community.

A tribute to Alain Garrigue (1960-2003) and his family

CERN Multimedia

2004-01-01

The tragic death of Alain Garrigue, his wife Christine, and their two children Simon and Marjorie, victims of the Charm-el-Cheikh air disaster in Egypt, is a great shock, and a source of immense sadness to all of us. We will remember Alain both as a colleague and as a friend. He communicated to all his «joie de vivre», and he established a strong team spirit within the group which he led at the LPSC Grenoble. His career as an engineer took him through CNES (Centre National d'Etudes Spatiales), RENAULT and CEA in Grenoble. His arrival at the LPSC brought a new dimension to the mechanics group, where Alain developed activities in cryogenics. Alain brought indispensable theoretical knowledge to the LPSC Atlas group. His participation enabled the laboratory to progress in development of proximity cryogenics for the ATLAS electromagnetic calorimeter. He directed technical activity and coordinated construction of this equipment. His attention to technical details never distracted him from a gl...

The present study assessed the composition of the phytoplankton community and the physicochemical variables in an area located within the ore treatment unit - Brazilian Nuclear Industries, in Caldas and also in 'Antas' dam, which is under the influence of the treatment unit. Water samples were taken from three sites; one located within the treatment unit (site CM), which receives non-treated effluents generated during the mining process; and the other sites are located in 'Antas' dam (sites Cab and 41). We determined the values of dissolved oxygen, pH, chlorophyll a, hardness, thorium, uranium, sulfate and total organic nitrogen in water samples, and identified the phytoplankton community in October 2008 and January 2009. Water samples from the site CM exhibited lower pH medium values (3.9) than from the site 41 (6.9). The highest medium value of chlorophyll a was detected in water samples at site CM (5 μg L -1 ), whereas the lowest value was recorded at site 41 (0.47 μg L -1 ). Higher medium values of sulfate were detected in water samples from site CM (1743 mg L -1 ) compared to site Cab (110.11 mg L -1 ). We identified six classes in the phytoplankton community at site CM and eight classes at sites Cab and 41. Total average density of phytoplankton were 444 ind mL -1 , 316 ind mL -1 and 303 ind mL -1 at points Cab, 41 and CM, respectively. The results obtained show that the environmental conditions at site CM are not favorable to the maintenance of a high density in the phytoplankton community. (author)

The fundamental condition for the bioleaching of the uranium ore is the presence of metallic sulfide such as pyrite associated with the ore, which is found in the ore and in the waste at the Unidade de Tratamento de Minerio (UTM) of Pocos de Caldas, State of Minas Gerais, Brazil. The present study aims to determine the chemical and microbiological characteristics in effluents of uranium mining from the UTM and in Antas dam, which receives treated effluents from the UTM. Water samples were collected Pit Mine (CM), located within the UTM facilities and from site 41 (Antas dam) in July and October 2008. We verified low pH values in water samples from CM (3.7) in comparison to the ones found at site 41 (6.65). There was a higher medium density value of Acidithiobacillus ferrooxidans, Acidithiobacillus thiooxidans and heterotrophic acidophilic bacteria in water samples at site CM compared to the values recorded from samples at site 41. Medium values of Fe{sup 2+}, uranium and zinc in samples from the site CM were higher than at site 41. The concentration of fluoride (68.5 mL{sup -l}) and manganese (2.34 mL{sup -1}) in water samples from site 41 were above the limits fixed for water bodies in Resolution CONAMA 357. The relative seasonal variation of some variables observed at site CM (low pH values, high densities of Acidithiobacillus sp. and heterotrophic acidophilic bacteria) shows that this site is one of the main sites of occurrence of acid mine drainage and action of bioleaching bacteria at UTM.

Further studies on hydration of alkynes by the PtCl4-CO catalyst

Energy Technology Data Exchange (ETDEWEB)

Israelsohn, Osnat; Vollhardt, K. Peter C.; Blum, Jochanan

2002-01-18

Under CO atmosphere, between 80 and 120 C, a glyme solution of PtCl{sub 4} forms a carbonyl compound that promotes hydration of internal as well as terminal alkynes to give aldehyde-free ketones. The catalytic process depends strongly on the electronic and steric nature of the substrates. Part of the carbonyl functions of the catalyst can be replaced by phosphine ligands. Chiral DIOP reacts with the PtCl{sub 4}-CO compound to give a catalyst that promotes partial kinetic resolution of a racemic alkyne. Replacement of part of the CO by polystyrene-bound diphenylphosphine enables to attach the catalyst to the polymeric support. Upon entrapment of the platinum compound in a silica sol-gel matrix, it reacts as a partially recyclable catalyst. A reformulated mechanism for the PdCl{sub 4}-CO catalyzed hydration is suggested on the basis of the present study.

Full Text Available Between 1654 and 1677 the furnishings of the main chapel of the Cathedral of Santiago were reformed following the new Baroque principles imported from Madrid and Italy. The resultant changes are those known today: canopy, camerina and pergola with Solomonic columns and the wooden revetments of the walls. The construction work was directed by the canon of the Cathedral, José de Vega y Verdugo, who had spent several years in Rome, and was carried out first by Francisco de Antas, master builder of the Cathedral, and later by the new master builder, Domingo de Andrade. The Roman sources for these structures —Bernini’s canopy in St. Peter’s Basilica and Constantine’s pergola of twisted columns— are here proposed or revised, with the addition of new graphic and literary data.

Background In order to increase access to drinking water in Africa there is more and more interest in the promotion of manual drilling techniques, without need of expensive drilling equipment, but they can be applied only in those areas with suitable hydrogeological conditions: thick layers of unconsolidated sediments and shallow groundwater level. Mapping of suitable zones for manual drilling at national level in Africa is a crucial activity and local institutions and UNICEF are implementing specific programs for its promotion, but the limitation in available data concerning shallow hydrogeological aquifers are limited. The research has been developed in the project "Use of remote sensing and terrain modeling to identify suitable zones for manual drilling in Africa and support low cost water supply", within the scientific cooperation between the University of Milano-Bicocca, Universite' Cheick Anta Diop (Dakar Senegal) , SNAPE - Service Nationale de Points d'Eau (Conakry Guinea), UNICEF Senegal and UNICEF Guinea. The project is funded by NERC (National Environmental Research Council, UK). Objective of the research: The presented work is only the starting point of the project aiming to elaborate an automatic procedures to manage and improve the existing database of borehole logs in Senegal and Guinea for the interpretation of shallow hydrogeological conditions and identification of suitable zones for manual drilling, in two pilot areas: Louga (Northwestern Senegal) and Faranah/Kankan (Eastern Guinea). Within the objective of the project is also considered the integration of Remote Sensing to support hydrogeological interpretation, especially where borehole logs are not present. Methodology Focus is to create a hydrogeological database, TANGAFRIC, to organize, codify and elaborate hydrogeological data. The metodology derives from the software TANGRAM (www.tangram.samit.unimib.it) produced by the University of Milano Bicocca, with innovative aspect of stratigraphic

2013-04-01

Torrential and heavy rains are frequent in Andalusia (Southern Spain) due to the characteristic Mediterranean climate (semi-arid areas). This, in combination with a massive occupation of floodable (river sides) and coastal areas, produces severe problems of management and damage to the population and social and economical activities when extreme events occur. Some of the most important problems are being produced during last years in Almería (Southeastern Andalusia). Between 27 and 28 September 2012 rainstorms characterized by 240mm in 24h (exceeding precipitation for a return period of 500 years) occurred. Antas River and Jático creek, that are normally dry, became raging torrents. The massive flooding of occupied areas resulted in eleven deaths and two missing in Andalucía, with a total estimated cost of all claims for compensation on the order of 197 million euros. This study presents a probabilistic flood forecasting tool including the effect of river and marine forcings. It is based on a distributed, physically-based hydrological model (WiMMed). For Almería the model has been calibrated with the largest event recorded in Cantoria gauging station (data since 1965) on 19 October 1973. It was then validated with the second strongest event (26 October 1977). Among the different results of the model, it can provide probability floods scenarios in Andalusia with up 10 days weather forecasts. The tool has been applied to Vera, a 15.000 inhabitants town located in the east of Almería along the Antas River at an altitude of 95 meters. Its main economic resource is the "beach and sun" based-tourism, which has experienced an enormous growth during last decades. Its coastal stretch has been completely built in these years, occupying floodable areas and constricting the channel and rivers mouths. Simulations of the model in this area for the 1973 event and published in March 2011 on the internet event already announced that the floods of September 2012 may occur.

The SnIV atoms are then pentacoordinated, with a common trans trigonal–bipyramidal arrangement. The asymmetric unit contains one half-molecule, which is completed by inversion symmetry in space group type C2/c. The inversion centre is placed at the mid-point of the central bis-monodentate oxalate dianion, C2O42−, which bridges the [(SnPh3(DMSO] moieties. The molecule crystallizes as a disordered system, with two phenyl rings disordered by rotation about their Sn—C bonds, while the DMSO molecule is split over two positions due to a tetrahedral inversion at the S atom. All disordered parts were refined with occupancies fixed of 0.5.

The resultant [α- 11 C]-4-arylene-2-atyl-5-oxazolones were hydrogenated after ring opening, using the chiral rhodium complex of (R)-1,2-bis(diphenylphosphino)propane [(R)-PROPHOS] or (+)-2,3-isopropylidene-2,3-dihydroxy-1,4-bis(diphenylphosphino)butane [(+)-DIOP]. After removal of the amino protecting group, the labelled amino acid was obtained on purification by preparative LC in 10-15% radiochemical yield, and radiochemical purity higher than 95% from [ 11 C]carbon dioxide within 60 min. The optical purity of the products determined by the tRNA method and capillary GC, was 80 and 60% e.e., respectively (i.e. L/D=90/10 and 80/20). (author)

Full Text Available En este artículo se analiza el derecho a contraer nupcias en situaciones de inmigración, mostrando las diferencias ideológicas que pueden ocurrir en los Estados de origen y destino en la forma de concebir el matrimonio. El artículo se centra en la experiencia de los inmigrantes islámicos en España. Un tema especialmente difícil es el matrimonio poligámico, institución arraigada en los países islámicos que ha planteado varios problemas, especialmente desde la perspectiva jurídica. La solución a la que se ha llegado en España procede de la vía jurisprudencial y tiene como punto de referencia dos casos: el de Diop, un inmigrante senegalés que fallece dejando dos viudas, y el de un trabajador marroquí, que había estado casado con dos mujeres a la vez durante un periodo, quien muere tras haberse divorciado de una de ellas

Full Text Available The genus Dimorphandra has distinguish relevance considering either medicinal or biodiversity aspects because it includes two species that are economically important flavonoids sources for pharmachemical industry (D. mollis Benth. and D. gardneriana Tul., and species endemic to Brazil, such as D. jorgei Silva and D. wilsonii Rizz., threatened by extinction. In order to evaluate variability among accessions of D. mollis (fava-d'anta, D. gardneriana and D. wilsonii, it was collected fruit from individual plants from three Brazilian states in a total of 57 accessions, which were analyzed with RAPD markers. It was used 20 seeds per progeny; the DNA was extracted from fully-formed young leaves, which were collected in bulk. The data were analyzed using a binary matrix, in which the score one represented presence of a band and zero, absence. The similarity matrix was developed by using the arithmetic complement of the Jaccard index, later grouped based on the Neighbor Joining algorithm. It was found considerable intra and inter specific variability in Dimorphandra spp., which were separated into four groups. Though genetic variability was found, the collecting trips showed that most of these areas are subject to loss of genetic resources of fava-d'anta due to the following factors: continuous anthropic activity, propensity for natural fires, and loss of natural seed dispersers (large fruit-eating mammals. Therefore, protections of these areas and ex situ conservation are essentials for the maintenance of genetic variability of these species.O gênero Dimorphandra tem grande relevância, sobretudo nos aspectos medicinais e de biodiversidade, por incluir duas espécies que são importantes economicamente como fontes de flavonoides para indústria farmacoquímica (D. mollis Benth. e D. gardneriana Tull., e espécies endêmicas do Brasil, como a D. jorgei Silva e D. wilsonii Rizz., sendo esta ameaçada de extinção.

Full Text Available Os modelos de simulação são ferramentas úteis na análise das inter-relações bioecológicas dos carrapatos. Partindo dessa premissa, objetivou-se avaliar o desempenho do programa BABSIM como auxiliar no estudo epidemiológico de B. microplus para o Estado de Minas Gerais, validando-se os ajustes no programa pela análise comparativa das curvas populacionais observadas e simuladas em Pedro Leopoldo e São Miguel do Anta, MG. As simulações foram realizadas com o programa BABSIM utilizando-se os parâmetros biológicos originais do programa e com ajustes nas temperaturas mínimas para oviposição e incubação dos ovos, no índice de encontro do hospedeiro pelas larvas, e no índice de sobrevivência dos estádios de vida livre. Os ajustes nos parâmetros biológicos propiciaram aumento na intensidade da carga parasitária, porém não foram suficientes para representar com maior precisão a dinâmica populacional no ecossistema em São Miguel do Anta. As simulações procedidas com os parâmetros biológicos originais e ajustados apresentaram comportamento variável para os diferentes anos em relação aos observados no estudo experimental de Pedro Leopoldo. Apesar de os resultados das simulações terem contribuído para a análise do conjunto de variáveis que interagem para determinar as variações do tamanho das populações de carrapatos nos ecossistemas estudados, eles indicaram, também, a necessidade de introduzir modificações nos submodelos que representam as inter-relações parasito-ambiente antrópico, assim como a necessidade de modificar o programa para permitir alterações de manejo dos animais, dentro de um mesmo ano de simulação, e, dessa maneira, justificar com maior precisão a dinâmica populacional em diferentes tipos de ecossistemas.

Así, mientras la caída de la fecundidad y la estabilización de las tasas de mortalidad han contribuido a un progresivo retroceso de la vitalidad natural, la masiva emigración de antaño ha dado paso al papel de Andalucía como incipiente foco de inmigración y al creciente protagonismo de movimientos internos de relocalización de la población. Desde el punto de vista territorial estas afirmaciones quedan matizadas por los notables contrastes que se producen entre los distintos ámbitos que conforman la región y que contraponen al medio rural con el urbano, al litoral con el interior o a las grandes ciudades con sus periferias.

Full Text Available ABSTRACT Vegetable oils present important pharmacological properties, which gained ground in the pharmaceutical field. Its encapsulation in nanoemulsions is considered a promising strategy to facilitate the applicability of these natural compounds and to potentiate the actions. These formulations offer several advantages for topical and systemic delivery of cosmetic and pharmaceutical agents including controlled droplet size, protection of the vegetable oil to photo, thermal and volatilization instability and ability to dissolve and stabilize lipophilic drugs. For these reasons, the aim of this review is to report on some characteristics, preparation methods, applications and especially analyze recent research available in the literature concerning the use of vegetable oils with therapeutic characteristics as lipid core in nanoemulsions, specially from Brazilian flora, such as babassu (Orbignya oleifera, aroeira (Schinus molle L., andiroba (Carapa guaianiensis, casca-de-anta (Drimys brasiliensis Miers, sucupira (Pterodon emarginatus Vogel and carqueja doce (Stenachaenium megapotamicum oils.

Full Text Available El servicio doméstico figura entre los mercados de trabajo secundarios que han cobrado vigencia en el contexto de la globalización. Su dinamismo se relaciona con la demanda de fuerza de trabajo femenina barata para satisfacer necesidades de atención en la esfera de la reproducción doméstica. La caracterización del mercado de trabajo del servicio doméstico en Estados Unidos a principios del siglo XXI con base en datos de encuesta muestra que -ahora como antaño- su crecimiento descansa principalmente en la afluencia de fuerza de trabajo inmigrante, que en nuestros días es principalmente latinoamericana. El nivel de pobreza que acusan y su baja escolaridad, corroboran que el crecimiento de este mercado de trabajo en las sociedades desarrolladas es una más de las secuelas regresivas del mundo del trabajo en el contexto de la globalización.

2007-09-01

The Personality Assessment Inventory's (PAI's) ability to predict psychopathic personality features, as assessed by the Psychopathy Checklist-Revised (PCL-R), was examined. To investigate whether the PAI Antisocial Features (ANT) Scale and subscales possessed incremental validity beyond other theoretically relevant PAI scales, optimized regression equations were derived in a sample of 281 Canadian federal offenders. ANT, or ANT-Antisocial Behavior (ANT-A), demonstrated unique variance in regression analyses predicting PCL-R total and Factor 2 (Lifestyle Impulsivity and Social Deviance) scores, but only the Dominance (DOM) Scale was retained in models predicting Factor 1 (Interpersonal and Affective Deficits). Attempts to cross-validate the regression equations derived from the first sample on a sample of 85 U.S. sex offenders resulted in considerable validity shrinkage, with the ANT Scale in isolation performing comparably to or better than the statistical models for PCL-R total and Factor 2 scores. Results offer limited evidence of convergent validity between the PAI and the PCL-R.

Bioclimatic changes and landslide recurrence in the mountainous region of Rio de Janeiro: are we ready to face the next landslide disaster?

Paleo-environmental studies point out an alternation of wet and dry periods during the Holocene in southeastern Brazil, marked by the expansion and retraction of the humid tropical rainforest in alternation with the campos de altitude vegetation ('high altitude grassland'); successive episodes of natural fire were recorded from 10,000 to 4,000 years BP in the mountainous region of SE-Brazil, reflecting warm-dry conditions. Present seasonal climatic variability is indicated by an increasing dry spell frequency throughout the XX and early XXI centuries together with an increasing rainfall concentration in the summer when extreme daily totals (above 100 mm) become progressively more frequent. Historical land use changes, at both regional and local scales, are mostly related to this climatic variability. Therefore extreme rainfall induced landslides have been responsible for severe disasters as recorded along the Atlantic slopes of Serra do Mar. The extreme one occurred in January 2011, affecting the municipalities of Nova Friburgo, Teresópolis and Petrópolis. Studies in Nova Friburgo shown the occurrence of 3.622 landslides scars within an area of 421 km2; this rainfall event reached the expected average monthly rainfall (300 mm) in less than 10 hours. The D'Antas creek basin (53 km2) was the most affected area by landslides; 86% of 326 scars where associated with shallow translational mechanisms among which 67% occurred within shallow concave up topographic hollows of 32° slope angle in average. Most of these landslide scars occurred in granite rocks and degraded vegetation due to historical land use changes (last 200 years) including secondary forest (64%) and grasslands (25%). The present-day association between extreme rainfall induced landslides and human induced vegetation changes seem to reflect similar geomorphic responses to natural Holocene bioclimatic changes; a common phenomenon between the two periods is fire (natural fire in the past time and man

Full Text Available ABSTRACT The tree Piptadenia gonoachantha is widely used in forestry and in forest restoration projects, which require methods for evaluating tree growth. Long-term studies are necessary to determine patterns and detect changes in species growth rhythms. Tree ring analysis provides a precise method for determining age and documenting long-term growth trends in tropical tree species. The present study evaluated the periodicity of tree ring formation and radial growth dynamics of P. gonoachantha from a population of known age in the Poço das Antas Biological Reserve. Two radii from six trees were sampled using non-destructive methods. Tree rings were counted and measured to estimate age and to calculate diametric increment. All samples had 16 tree rings, which matched the known plantation age and confirmed the annual formation of rings. The individuals sampled had a mean annual diametric increment of 9.5 mm / year. Results showed a trend towards decreasing growth rate with increasing age. Individuals of P. gonoachantha in Ombrophilous Dense Forest produce annual tree rings, which holds potential for future dendroecological studies.

Se destaca el bajo porcentaje de este tipo de usos respecto al total de datos etnobotánicos recopilados para los Chorote (15 %. De su comparación con la farmacopea criolla se desprende que el 52 % de los datos resulta idéntico, por lo que se concluye que los Chorote habrían adquirido estas prácticas a manera de préstamo cultural. La farmacopea de este pueblo, entonces, fue muy reducida debido a que su medicina tradicional de corte chamanístico no involucraba antaño el uso de remedios de origen vegetal. Entre las plantas medicinales típicamente Chorote se pueden citar a Achatocarpus praecox, Cleistocactus baumannii, Echinopsis rhodotricha y Funastrum clausum. Los usos estrictamente Chorote quedarían así reducidos a 90 aplicaciones en total, principalmente como antiemenagogos, antidiarreicos, antitusivos y cicatrizantes.

Full Text Available Dimorphandra mollis Benth., Fabaceae, also known as "faveira" or "fava-d'anta", is a plant common to the central woodsy meadow region of Brazil. It is well known for its antioxidant, antiplatelet and, principally, vasoprotective properties. Its principal component is rutin. The objective of this study is the evaluation of the safety of the use of the dried D. mollis extract in rodents. The rutin content of the standardized extract was 76.0±3%. With respect to the biochemical and hematological parameters evaluated, no alterations in the groups of rats that received 1000 and 2000 mg/kg doses of D. mollis were observed, but an increase in eosinophiles occurred. Hyperactivity of the white splenic pulp was detected in the group that received the 2000 mg/kg dose of D. mollis. In the evaluation of the lymphproliferative response with 1000 and 2000 mg/kg, no alterations were observed, and a decrease in IgG was only observed in the studies with a 2000 mg/kg dose. The results obtained with rodents suggest that no toxicity exists with the administration of dried D. mollis extract in a 1000 mg/kg dose.

Esta breve reflexión, en cambio, retoma la noción de “alma bella” según Hegel y luego Lacan, para producir un pequeño giro introduciendo la noción el “cuerpo feo” como alternativa a dicha posición subjetiva. Analizamos dos ejes: 1- cómo entender la “fealdad” del cuerpo sin caer en una propuesta dualista o idealista; 2- revisamos la noción lacaniana de “rectificación subjetiva” y su posible aplicación política.

Volcanic extrusion is one of the main causes for the high levels of environmental radioactivity in the region of Poços de Caldas (MG, Brazil). Uranium mining during the 80's further increased the background radiation in the region, especially in the Ribeirao das Antas watershed, where Bortolan Dam is located. Besides the uranium mining facility operating in the region, other activities, such as agriculture, were also responsible for the enhancement of the levels of radioactivity. The dam sediment profile provides an appropriate compartment for the study of the temporal variation of these radionuclides and for the evaluation of anthropogenic contamination. The main aim of this study is to evaluate the sedimentation rate and the dating of a profile collected in Bortolan Dam, by using the geochronology method. The activity concentration of "2"2"6Ra and "2"1"0Pb were measured in the sediment profile by gamma spectrometry. The concentration of "2"2"6Ra and "2"1"0Pb varied from (217 ± 9) Bq kg"-"1 to (286 ± 12) Bq kg"-"1 and from (262 ± 11) Bq kg"-"1 to (322 ± 34) Bq·kg"-"1 respectively; and the sedimentation rates varied from 0.021 to 0.144 g cm"-"2y"-"1.

Full Text Available «No cabe resurgimiento sin una fortaleza militar. No olvidemos que nuestra grandeza duele a poderosas naciones». Muy pocos oyentes dejarían de comprender que con estas palabras Franco aludía, en su mensaje de fin de año de 1939, a Francia y Gran Bretaña, las dos potencias que en la mitología de la extrema derecha eran las responsables de que España hubiera perdido su poderío internacional de antaño. Recuperarlo era para el caudillo vencedor en la guerra civil un objetivo digno de la elevada imagen que se había hecho de si mismo y para ello la guerra europea, iniciada pocos meses antes, ofrecía una oportunidad. Pero a su vez Franco era consciente de que España no estaba en condiciones de enfrentarse a las dos potencias de Europa occidental e incluyó en su mensaje un llamamiento a que se pusiera fin al conflicto. No se abstuvo sin embargo de proclamar que la responsabilidad en provocarlo la habían tenido en gran parte «los especuladores internacionales, dueños y señores del régimen liberal y de la injusticia imperante en el mundo», retorcida expresión con la que sin duda aludía a las democracias capitalistas de Occidente.

Full Text Available The author discusses the relocation of Panamá City to its current site, as well as the morphological characteristics that made it both a fortress and a market place. In its new location, the city continued to play to role of the sea port and commercial center that it played before by being a key stop in the silver route and house of trade of the Americas; but the new city was surrounded by the wall, and built according to a plan that is the perfect example of the classic colonial city in Spanish America.

Se analiza aquí el traslado de la ciudad de Panamá la Vieja a su actual emplazamiento y las características morfológicas que la convierten en una ciudad "fortaleza y mercado" a la vez, dado que sigue desempeñando la misma función portuaria y comercial que antaño: la de centro neurálgico del comercio americano y puerto de tránsito y transbordo en la ruta de la plata, sólo que ahora su perímetro urbano es ceñido por un gran cinturón abaluartado y su trazado reproduce con gran perfección el modelo clásico de la ciudad americana colonial.

Full Text Available The distribution and beta diversity of oligochaete assemblages were investigated in different spatial scales to verify the influence of environmental factors and geographic distance on their structure. Two types of mesohabitats (riffles and pools were sampled in eight first-order streams located in four preservation areas (Poço D’Anta Municipal Biological Reserve, Santa Cândida Municipal Biological Reserve, Ibitipoca State Park and a private farm called Fazenda Floresta and two Atlantic Forest phytophysiognomies (Seasonal Semideciduous Forest and Rocky Field. Variations in the taxon richness, abundance and composition of the oligochaete assemblages occurred between streams and phytophysiognomies, but not between riffles and pools in the same stream. Low beta diversity values were found and both turnover and nestedness contributed similarly in the environments studied, which could have occurred because of the high capability of oligochaetes to adapt to different environmental conditions. Although the canonical correspondence analysis explained 85.5% of the data (first three axes, the partial Mantel test showed greater influence of geographic distance on the faunal composition than the environmental variables measured. Simple linear regression confirmed this result and showed that the decay of similarity increased with distance between streams. The information from this study sheds light on how environmental and spatial factors determine the variation in the distribution and diversity of oligochaetes in forested low-order streams.

Full Text Available In the city of Bueno Brandão, South of Minas Gerais State, Brazil, the Watershed of Rio das Antas is located prior to the public water supply and is susceptible to hydro-degradation due to the intensive agricultural activities developed in the area. The potato plantation is the most significant cropping in the city. Because of the possibility of interfering in the preservation areas, mainly the ones surrounding water courses and springs, it is very important to do the assessment of the plantation sites, in order to avoid the risk of water contamination. The procedures adopted by the agro activity farmers generally present the following features: intensive use of agro-chemicals, cropping in places with slopes which are higher than 20%, close to or in permanent preservation areas. The scope of this study was to develop the proper methodology for the assessment of the plantation areas, regarding the short time of procedure, as the period between the plantation and the harvest occurs in six months the furthest. These areas vary year in year out, as the plantation sites often change due to the land degradation. Because of that, geotechnologies are recommended to detect the plantation areas by the use of satellite images and accurate data processing. Considering the availability of LANDSAT medium resolution images, methods for their appropriate classification were approached to provide effective target detection.

Mass movements are recurrent phenomena in the whole Mountain Region of the State of Rio de Janeiro in Brazil. These events actively participate in the relief evolution and are also responsible for many damages and loss of human lives. The triggering of these events depends on the natural environment and the preparatory and immediate action of the physical, biotic and human agents responsible for these processes. This work is based on the hypothesis in which the topographical conditions have a major effect on the spatial distribution of translational landslides caused by decreased of the internal resistance of the material mobilized. Therefore, the purpose of this study is to identify the topographical conditions favorable to landslide triggering based on morphometric analysis in a pilot watershed - D'antás watershed - located in the mountainous region of the State of Rio de Janeiro. The indices include the topographic wetness index (TWI), contributing area, slope angle and elevation and were derived from 5-m grid digital terrain model, computed on a Geographic Information System (GIS). The maps produced allowed the analysis of topographic influence on the landslides distribution from the indices of frequency classes (F), concentration of scars (CC) and potential of landslide (PL). The landscape sectors that are more likely to be affected by landslides were the ones where the elevation ranges from 1070m - 1187m, slope angle between 40.95° and 47.77°, contributing area between (log10) 1.32 m² - 1.95 m² and topographic wetness index between 7.11 to 9.59. This work provides important information which may help in the decision-making process, using fewer data and indices of easy application. Finally, the results obtained will subsidize of a landslide susceptibility map through the implementation of the conditional probability method aimed at predicting and mitigating of the damage caused by landslides.

Halldin, C.

1984-01-01

The use of 11 C-labelled aromatic amino acids in positron emission tomography (PET) and their importance in physiological studies, especially cerebral protein synthesis or their role as precursors of neurotransmitters, is discussed. The synthesis of 11 -C-labelled aromatic amino acids by various routes is presented and new 11 C-labelled precursors, aromatic and aliphatic 11 C-aldehydes, are reported. The 11 C-aldehydes were obtained in 60-95% radiochemical yield and reaction times were of the order of 5 min. The 11 C-aldehydes have been used in condensation reactions with 2-aryl-5-oxazolones in the presence of a tertiary amine, diazabicyclooctane (DABCO), to produce the corresponding [α- 11 C]-4-arylene-2-aryl-5-oxazolones. Ring opening, hydrogenation and removal of protecting groups were carried out in one step to produce the racemic [3- 11 C]-labelled aromatic amino acids in 8-30% radiochemical yield. The total reaction time was 52-60 min. L-[3- 11 C]Phenylalanine was obtained by a seven-step synthesis in 80% e.e. (enantiomeric excess) and 60% e.e., respectively, in 10-15% radiochemical yield within 60 min, by use of the chiral rhodium complex of (R)-1,2-bis(diphenylphosphino)propane ((R)-PROPHOS) or (+)-2,3-isopropylidene-2,3-dihydroxy-1,4-bis(diphenylphosphino)butane ((+)-DIOP) in the hydrogenation reaction. Racemic [2- 11 C]-labelled aromatic amino acids were produced by a high-pressure, high-temperature modification of the Buechere-Strecker synthesis. [2- 11 C]Phenylglycine was obtained in 20% radiochemical yield within 50 min. [3- 11 C]Phenylpyruvic acid was prepared via the aldehyde-oxyzolone condensation reaction in 40% radiochemical yield within 40 min (not including LC separation). Its use in the synthesis of [3- 11 C]-phenylalanine by enzymatic transamination is also discussed. With 32 refs.(Author)

Osteoarthritis (OA) may result from intrinsic inflammation related to metabolic disturbance. Obesity-associated inflammation is triggered by lipopolysaccharide (LPS) derived from the gut microbiota. However, the relationship between gut microbiota, LPS, inflammation, and OA remain unclear. To evaluate the associations between gut microbiota, systemic LPS levels, serum and local inflammatory profiles, and joint damage in a high fat/high sucrose diet induced obese rat model. 32 rats were randomized to a high fat/high sucrose diet (diet-induced obese (DIO), 40% fat, 45% sucrose, n = 21) or chow diet group (12% fat, 3.7% sucrose n = 11) for 28 weeks. After a 12-week obesity induction period, DIO animals were stratified into Obesity Prone (DIO-P, top 33% by change in body mass, n = 7), and Obesity Resistant groups (DIO-R, bottom 33%, n = 7). At sacrifice, joints were scored using a Modified Mankin Criteria. Blood and synovial fluid analytes, serum LPS, and fecal gut microbiota were analyzed. DIO animals had greater Modified Mankin scores than chow animals (P = 0.002). There was a significant relationship (r = 0.604, p = 0.001) between body fat, but not body mass, and Modified Mankin score. Eighteen synovial fluid and four serum analytes were increased in DIO animals. DIO serum LPS levels were increased compared to chow (P = 0.031). Together, Lactobacillus species (spp.) and Methanobrevibacter spp. abundance had a strong predictive relationship with Modified Mankin Score (r(2) = 0.5, P gut microbiota and adiposity-derived inflammation and metabolic OA warrants further investigation.

However, no attempt has been made to establish an iterative measurement of 6MWD during the overall period of pulmonary rehabilitation. Therefore, the aim of this study was to evaluate the impact of a twelve-week rehabilitation program on the iterative weekly measurement of 6MWD in chronic obstructive pulmonary disease (COPD patients and healthy subjects.Methods: Twenty-six patients with COPD and nine age-matched healthy subjects were studied. Measurements were taken at baseline and after twelve weeks except for the 6MWD. The exercise measurements included a six-minute walking test (6MWT and an incremental exercise test. Oxygen saturation, heart rate, and dyspnea will be monitored during all these tests. Results: At baseline there were significant differences between groups, except in age, body mass index, and oxygen saturation. After 12 weeks, there was no significant change in lung function in patients with COPD and healthy subjects. The 6MWD, peak oxygen uptake VO2peak and anaerobic threshold increased significantly after training in both groups (P < 0.01. The averaged trace of the 6MWD of patients with COPD and healthy subjects was followed-up respectively by a logarithmic and linear fitting. 6MWD showed a plateau after eight weeks in patients with COPD, however, it increased continually overall in healthy subjects.Conclusion: Both patients with COPD and healthy subjects demonstrated functional responses to training but with

This study aims to assess the environmental radiological impact (ERI) from the release of wastewaters used by the Mining Industrial Complex at Poços de Caldas (CIPC), today called Ore Treatment Unit (UTM) in Caldas, MG, Brazil, during the period 1999-2009. The effluent waters were analyzed once a week at point 014 (associated with the mine and waste pile 8). Critical radionuclides are 238 U, 226 Ra, 210 Pb, 232 Th and 228 Ra. The 238 U and 232 Th were analyzed by spectrophotometry. The 226 Ra, 210 Pb and 228 Ra, in turn, were analyzed by radiochemical separation methods and subsequent radiometry. The dose estimates were based on the model proposed by the National Nuclear Energy Commission (CNEN) for a hypothetical critical group associated with the point of effluents release into the river Ribeirao das Antas (point 014). The maximum dose rate allowed by CNEN for release is equal to 0.3 mSv·y -1 for individuals of the critical group. Our calculations were performed using the average concentration along the ten years period study. The estimated dose value for the individual of the critical group was 0.12 mSv·y -1 . It may be concluded that the reference levels established by CNEN were not reached. This indicates that the treatment of effluents generated by the CIPC/UTM was conducted efficiently, ensuring the safety of the population living in the surroundings of the Ore Processing Unit (UTM) at Caldas.

Water samples collected at these points were analyzed for U nat , 226 Ra, 210 Pb, 232 Th and 228 Ra content in the particulate and soluble fractions, and the behavior of radionuclide releases and their fractions was investigated. U nat and 228 Ra showed identical behaviors at these three points. U nat at point 014 (waste pile) behaved different from described in recent literature data. The isotopes of Ra should exhibit the same behavior at each point, but this was not observed at point 025 (waste pond). 232 Th release showed equal activity concentration near the waste pile (point 014) and near the waste pond (point 025), whilst near the open pit mine (point 076) the soluble fraction showed a concentration of activity greater than the particulate fraction. Finally, 210 Pb showed a different behavior at each point. Due to the great differences in behaviors of each radionuclide, it was not possible to establish a temporal pattern of release which requires assessment over a longer period of time. (author)

Full Text Available El protocolo, desde sus inicios, se ha ido adaptando a la gran transformación que ha ido experimentando nuestra sociedad y se ha modernizado hacia un mayor funcionalismo y practicidad para ir aportando las soluciones que la realidad va requiriendo. Un protocolo cada vez más simple y efectivo que ha ido dejando atrás la pompa y el boato de antaño. Aun así los medios de comunicación no reflejan esta realidad y siguen representando el protocolo como algo “anclado en el pasado”, casi como obsoleto. Por lo tanto, el objetivo de este artículo es poner de manifiesto la negativa realidad que vive el protocolo en la prensa de nuestro país, para manifestar, en último término, la perjudicial influencia de esta representación para la imagen que esta disciplina tiene en nuestra sociedad. La representación que del protocolo hace la prensa es esencial para una correcta percepción del mismo. Tras llevar a cabo un riguroso análisis del discurso, se pondrán de manifiesto las negativas connotaciones del discurso del protocolo en la prensa, con sus desfavorables consecuencias para la percepción del mismo en la sociedad. En este artículo, por tanto, se reivindica la importancia del binomio protocolo-medios de comunicación, imprescindible para una buena gestión de la comunicación.

Full Text Available Este artículo analiza cómo autores de literatura infantil portuguesa consiguieron eludir la censura en tiempos de la Dictadura (1926-1974 y publicar obras cuyos mensajes, que no podían ser discutidos libremente, fueron transmitidos a los jóvenes lectores del momento. Los objetivos de este estudio son dar a conocer obras de literatura infantil editadas durante la Ditadura y leídas por las jóvenes generaciones de antaño y actuales; establecer qué temas y valores son presentados en estas obras y comprender qué mecanismos fueron usados por los escritores para eludir la censura. Como metodología de estudio, empleamos el análisis hermenéutico a partir de una lectura crítica y reflexiva de los textos. De este análisis concluímos que estas obras abordan cuestiones relacionadas con el racismo y la promoción de la igualdad entre los hombres, la apología de libertad, la resistencia a la opresión y la exhortación a la paz. Los autores aquí estudiados emplean un lenguaje simbólico, cargado de metáforas, ambigüedades, humor e ironía, mecanismos todos ellos retóricos que fueron usados para transmitir su mensaje a los lectores y eludir así la censura del régimen vigente.

In the current study, water quality of five river sites in Parana River basin (Brazil), utilized for public water supply, was assessed through a set of biomarkers in fish Astyanax spp. Population growth and inadequate use of land are challenges to the preservation of biodiversity and resources such as water. Some physicochemical parameters as well as somatic indexes, gills and liver histopathology, genotoxicity, and biochemical biomarkers were evaluated. The highest gonadosomatic index (GSI) and antioxidant parameters (catalase and glutathione S-transferase activities, non-protein thiols), as well as the lowest damage to biomolecules (lipid peroxidation, protein carbonylation, DNA damage) were observed in site 0 (Piava River), which is located at an environmental protected area. Site 1, located in the same river, but downstream site 0 and outside the protection area, presents some level of impact. Fish from site 2 (Antas River), which lack of riparian forest and suffer from silting, presented the highest micronucleus incidence and no melanomacrophages. Differently, individuals from site 3 (Xambrê River) and site 4 (Pinhalzinho River) which receive surface runoff from Umuarama city, urban and industrial sewage, have the highest incidences of liver and gill histopathological alterations, including neoplasia, which indicated the worst health conditions of all sites. In particular, site 4 had high levels of total nitrogen and ammonia, high turbidity, and very low oxygen levels, which indicate important chemical impact. Comparison of the biomarkers in fish allowed classification of the five sites in terms of environmental impact and revealed that sites 3 and 4 had particular poor water quality.

This study aims to assess the environmental radiological impact (ERI) from the release of wastewaters used by the Mining Industrial Complex at Poços de Caldas (CIPC), today called Ore Treatment Unit (UTM) in Caldas, MG, Brazil, during the period 1999-2009. The effluent waters were analyzed once a week at point 014 (associated with the mine and waste pile 8). Critical radionuclides are {sup 238}U, {sup 226}Ra, {sup 210}Pb, {sup 232}Th and {sup 228}Ra. The {sup 238}U and {sup 232}Th were analyzed by spectrophotometry. The {sup 226}Ra, {sup 210}Pb and {sup 228}Ra, in turn, were analyzed by radiochemical separation methods and subsequent radiometry. The dose estimates were based on the model proposed by the National Nuclear Energy Commission (CNEN) for a hypothetical critical group associated with the point of effluents release into the river Ribeirao das Antas (point 014). The maximum dose rate allowed by CNEN for release is equal to 0.3 mSv·y{sup -1}for individuals of the critical group. Our calculations were performed using the average concentration along the ten years period study. The estimated dose value for the individual of the critical group was 0.12 mSv·y{sup -1}. It may be concluded that the reference levels established by CNEN were not reached. This indicates that the treatment of effluents generated by the CIPC/UTM was conducted efficiently, ensuring the safety of the population living in the surroundings of the Ore Processing Unit (UTM) at Caldas.

The geological survey of the Florianopolis Sheet (SG.22-Z-D-V) identified and characterized a calc-alkacic multi-intrusive and polydiapiric suite that occurs as a granitic batholite roughly concentric in texture and composition. This co-magmatic plutonic sequence is intrusive in the granite-gneissic basement of amphibolite facies, with which it was formerly confounded. The initial magmatic terms, put-in-place at the marginal portions of the batholite, are represented by quartz-diorites and tonalites (Forquilha Tonalites), followed by granodiorites (alto da Varginha Granodiorite), granodiorites to monzonites (Rio das Antas Granite) and completed by an inner portions of porphyritic monzonites (Sao Pedro de Alcantara Granite). The identifications of the compositional zoning that results from the development of the magmatic chamber is based on the examination of 74 rock samples that were analysed for major and minor oxides and trace elements (Ba, F, Li, Mo, Sn, W, Y, Rb, Nb, Zr and Sr). The treatment of these data shows the portions where mantle fractions predominate as well as the others where crustal meltings dominate, what demonstrates an origin by in situ differentiation processes, fractioning and different degrees of magmatic mixing. Geochronologic dating by Rb/Sr, K/Ar and U/Pb methods show isochronic and conventional ages of 600 to 700 m.y. that roughly are in accord with the temporal progress towards the younger felsic phases, putting this suite in the Upper Proterozoic age. The initial Sr sup(87) / Sr sup(86) ratios, around 0.710, point to a crustal origin with variable mantle contribution to these rocks. (author)

To study the perception of light distortion after refractive lens exchange (RLE) with diffractive multifocal intraocular lenses (IOLs). Clínica Oftalmológica das Antas, Porto, Portugal. Retrospective comparative study. Refractive lens exchange was performed with implantation of an AT Lisa 839M (trifocal) or 909MP (bifocal toric) IOL, the latter if corneal astigmatism was more than 0.75 diopter (D). The postoperative visual and refractive outcomes were evaluated. A prototype light-distortion analyzer was used to quantify the postoperative light-distortion indices. A control group of eyes in which a Tecnis ZCB00 1-piece monofocal IOL was implanted had the same examinations. A trifocal or bifocal toric IOL was implanted in 66 eyes. The control IOL was implanted in 18 eyes. All 3 groups obtained a significant improvement in uncorrected distance visual acuity (UDVA) (P refractive cylinder was less than 1.00 D in 86.7% of cases with the toric IOL. The mean light-distortion index was significantly higher in the multifocal IOL groups than in the monofocal group (P light-distortion index and CDVA. The multifocal IOLs provided excellent UDVA and functional UNVA despite increased light-distortion indices. The light-distortion analyzer reliably quantified a subjective component of vision distinct from visual acuity; it may become a useful adjunct in the evaluation of visual quality obtained with multifocal IOLs.

The Chironomidae occupy different habitats along the lotic system with their distribution determined by different factors such as the substrate characteristics and water speed. The input of vegetable material from the riparian forest allows a higher habitat diversity and food to the benthic fauna. The main aim of this paper is to verify the structure and spatial distribution of the Chironomidae fauna in different mesohabitats in a first order stream located at a Biological Reserve in the southeast of Brazil. In the months of July, August, and September 2007, and in January, February, and March 2008, samples were collected with a hand net (250 µm) in the following mesohabitats: litter from riffles, litter from pools, and sediment from pools. The community structure of each mesohabitat was analyzed through the abundance of organisms, taxa richness, Pielou's evenness, Shannon's diversity, and taxa dominance. Similarity among the mesohabitats was obtained by Cluster analysis, and Chironomidae larvae distribution through the Correspondence analysis. Indicator species analysis was used to identify possible taxa preference for a determined mesohabitat. The analyzed mesohabitats showed high species richness and diversity favored by the large environmental heterogeneity. Some taxa were indicators of the type of mesohabitat. The substrate was the main factor that determined taxa distribution in relation to water flow differences (riffle and pool). Stream characteristics such as low water speed and the presence of natural mechanisms of retention may have provided a higher faunistic similarity between the areas with different flows. The results showed that the physical characteristics of each environment presented a close relationship with the structure and spatial distribution of the Chironomidae fauna in lotic systems.

Full Text Available The transformation of the role of women over the course of the 20th century can be seen particularly clearly in the cinema. The analysis of various cinematic representations of Lady Marian, Robin Hood’s romantic partner, reveals the transformation in the female from feminine to heroic between 1922 and the present. This change involves Marian adopting male roles and being included in scenes that were previously reserved for male characters, together with a progressive masculinisation of women. Analysing films made in different decades shows how cinema always conveys a contemporary message, reflecting human and cultural models in keeping with the sensitivities of its viewers.La revolución histórica de la mujer a lo largo del siglo XX ha tenido su correlato en un testigo de excepción: el cine. El análisis de varias representaciones cinematográficas de Lady Marian, protagonista femenina de la leyenda de Robin Hood, desde 1922 hasta algunas de las producciones más recientes permite señalar que se ha producido un cambio en el papel de lo femenino en lo heroico. Este cambio pasa por la adopción de roles y la inclusión en escenarios antaño reservados para el protagonismo masculino, así como por una progresiva masculinización de la mujer. El análisis de las representaciones realizadas en cada década del siglo XX permite también comprobar cómo el cine siempre proyecta un mensaje contemporáneo, reflejando en sus historias modelos humanos y culturales acordes con la sensibilidad de cada tiempo.

Full Text Available Nas últimas décadas a expansão de plantações de Eucalyptus sp. foi notável no Brasil, destacando-se no cenário mundial. Diversos estudos revelam que tais plantações, especialmente aquelas respaldadas por instrumentos de certificação, podem trazer benefícios de cunho social e ambiental. Este trabalho apresenta dados coletados no período de 2002 a 2011 sobre a riqueza de plantas, aves e mamíferos em fazendas de plantação de eucalipto no Brasil. Discute-se sobre a importância dessas fazendas na conservação da biodiversidade, em que já foram registradas diversas espécies de plantas arbustivo-arbóreas, aves e mamíferos de médio e grande porte, respectivamente. Foi registrada a ocorrência de regeneração de plantas ameaçadas de extinção nos talhões de eucalipto: Araucaria angustifolia, Couratari asterotricha, Buchenavia hoehneana, Dalbergia nigra, Ocotea catharinensis e Ocotea porosa. Quanto às espécies da fauna ameaçadas de extinção, a águia-cinzenta (Urubitinga coronata, o chauá (Amazona rhodochorytha, o lobo-guará (Chrysocyon brachyurus, o tamanduá (Myrmecophaga tridactyla e a anta (Tapirus terrestris já foram observados. Plantações florestais e fragmentos compostos por vegetação secundária figurarão entre os principais elementos das paisagens tropicais futuras. Desta forma, não se pode negligenciar a contribuição das plantações de eucalipto na conservação da biodiversidade.

Full Text Available Abstract Background The aim of this study was to determine the risk for Bipolar Disorder (BD in Wilson’s disease (WD and to measure the impaired Quality of Life (QL in BD with WD using standardized psychiatric diagnostic tools and a case control design. Methods This was a case control study. The cases were 23 consecutive patients with WD treated at the University Hospital in Cagliari, Italy, and the controls were 92 sex- and age-matched subjects with no diagnosis of WD who were randomly selected from a database used previously for an epidemiological study. Psychiatric diagnoses according to DSM-IV criteria were determined by physicians using structured interview tools (ANTAS-SCID. QL was measured by means of SF-12. Results Compared to controls, WD patients had lower scores on the SF-12 and higher lifetime prevalence of DSM-IV major depressive disorders (OR = 5.7, 95% CI 2.4–17.3 and bipolar disorders (OR = 12.9, 95% CI 3.6–46.3. BD was associated with lower SF-12 in WD patients. Conclusions This study was the first to show an association between BD and WD using standardized diagnostic tools and a case control design. Reports in the literature about increased schizophrenia-like psychosis in WD and a lack of association with bipolar disorders may thus have been based on a more inclusive diagnosis of schizophrenia in the past. Our findings may explain the frequent reports of loss of emotional control, hyperactivity, loss of sexual inhibition, and irritability in WD patients. This study was limited by a small sample size.

In the months of Oct/2008 and Jan/2009 samples were collected for analysis of the protozooplanktonic community and physical and chemical variables in samples of water of the PM point and P41 point in the Antas Reservoir. The least values were verified of pH (Oct/08 = 4.10 and Jan/09 3.70) in samples of water of the PM point, when likened to the values detected in the P41 (Oct/08 = 7.20 and Jan/09 = 6.70). Elevated values of sulphate were detected in derived samples of water of the PM point (Oct/08 1832.0 mg.l -1 and Jan/09 = 1653.0 mg.l -1 ) when compared to those detected in the P41 point (Oct/08 = 386.7 mg.l -1 and Jan/09 = 7.42 mg.l -1 ). The composition of the protozooplanktonic community in samples of water of the PM point for the October presented less diversity of sorts when compared to the result obtained in sample of the P41 point, when three types registered only.

2011-01-01

Full Text Available En este ensayo se discuten dos conceptos clave para la revalorización de los quesos artesanales mexicanos: la genuinidad y la tipicidad. Primero, en la definición de queso se enfatiza en el producto auténtico, resultado de varios factores existentes en el territorio donde se elabora y se contrasta el tipo de productos que se comercializan actualmente en México con los que se fabricaban antaño. Se aborda el tópico de quesos y pseudoquesos,se propone una clasificación de quesos y productos similares, se destaca la importancia de la quesería artesanal. Se discute la genuinidad y se apunta a los rasgos esenciales de los quesos autenticos, se señala que se han identificado unas 40 variedades, destacando algunas como el queso asadero, el chihuahua y el cotija. Se aborda el concepto de tipicidad y sus dimensiones: el producto mismo, las prácticas de elaboración y su representación sociocultural. Se pone de relieve la relación producto-territorio, la tradición y la historia como fuentes de tipicidad. Finalmente, se enfatiza en la necesidad de revalorizar los quesos mexicanos genuinos porque constituyen un patrimonio cultural y contribuyen al desarrollo local. La caracterización de éstos destaca su genuinidad y tipicidad y podría favorecer la construcción de una figura de protección, por ejemplo una marca colectiva con referencia geográfica o una Denominación de Origen que permita asegurar una producción sostenida y su preservación.

Camera trap survey of medium and large mammals in a montane rainforest of northern Peru

Full Text Available Camera traps are a powerful tool for inventorying elusive and rare species and very useful to obtain ecologi- cal data for plans that involve wildlife conservation. In Peru, several surveys have been carried out in lowland Amazonia especially in the southeastern part of the country, but none in montane cloud forests or Yungas. We present the first camera trap studies produced in Peruvian Yungas at the locality of Querocoto village (Chota, Cajamarca, based on 2002 (dry season and 1264 (wet season camera traps-days (CTD. Two localities were surveyed in wet and dry season: The Pagaibamba Protection Forest and the San Lorenzo Forest. The wet season study was carried out in October and November, and the dry season in July to September of 2008. Eight mammalian species were recorded in both seasons. Some 66 (91.7% independent records were obtained in the dry season, but only six (8.3% in the wet one, suggesting a seasonality effect. The Mountain Paca Cunicu- lus taczanowskii was the most commonly photographed species, with 17.0 and 1.6 capture frequencies (dry and wet season respectively, whereas the Long-tailed weasel Mustela frenata (0.5 capture frequency in the dry season was the most rare species. Activity patterns suggest that Mountain Paca C. taczanowskii and the Andean Skunk C. chinga are nocturnal, while Spectacled Bear T. ornatus and Tayra E. barbara are diurnal in the study area. Our records of the Ocelot Leopardus pardalis and the Tayra E. barbara are among the highest altitudinal records known for each species. In addition, the Anta Tapirus pinchaque was also identified by its tracks, representing one of the first record known south of the Huancabamba Depression.

COMO MIEMBRO HONORARIO DE LA ACADEMIA NACIONAL DE MEDICINA DE COLOMBIA.

Hace ya muchos años, por allá en 1948, tuve el privilegio de conocer a Humberto Rosselli cuando llegó a trabajar en el Asilo de Locas, localizado en la vieja casa de la calle sa entre carreras 11 y 14, antaño denominada curiosamente "La Quinta de ninguna parte", nombre que tal vez en tiempos pasados no hubiera sido del todo inadecuado para una institución donde otrora reinaban la desolación y la desesperanza. 

A la sazón el Asilo estaba dirigido por Edmundo Rico, quien continuando la labor de Maximiliana Rueda y de Julio Manrique había renovado por completo la atención de los pacientes al mejorar todos los servicios y al abrir nuevos, tales como los de urología, neurología, ginecología y sobre todo, al haber vigorizado la enseñanza de la psiquiatría con sus vastos conocimientos y con su capacidad docente sin par. Señalo estos detalles porque fue este ambiente de ciencia y humanismo, semillero de muchos médicos y psiquiatras que han honrado la medicina, donde precisamente entró Humberto y donde, sin duda, afirmó su pasión por la psiquiatría. Fue allí donde se produjo el arranque de una carrera ininterrumpida de servicio, de investigación y de estudio, como médico, como impulsador de la psiquiatría, como profesor, como historiador y como ensayista. Me haría interminable si describiera toda su actividad y sus brillantes resultados.

Highlights: •Effect of non-zero angle of incidence on ps ablation of Ag investigated. •Ag colloids were evaluated by TEM, UV–vis absorption spectra and fs-DFWM. •30° incident angle provided Ag NPs of small size with higher yields. •FESEM, AFM, Raman data revealed the fabrication of Ag nanostructures. •Utility of Ag nanostructures surfaces for multiple SERS studies demonstrated. -- Abstract: Picosecond (ps) laser ablation of silver (Ag) substrate submerged in double distilled water was performed at 800 nm for different angles of incidence of 5°, 15°, 30° and 45°. Prepared colloidal solutions were characterized through transmission electron microscopy, UV absorption spectroscopy to explore their morphologies and surface plasmon resonance (SPR) properties. Third order nonlinear optical (NLO) characterization of colloids was performed using degenerate four wave mixing (DFWM) technique with ∼40 fs laser pulses at 800 nm and the NLO coefficients were obtained. Detailed analysis of the data obtained from colloidal solutions suggested that superior results in terms of yield, sizes of the NPs, SPR peak position were achieved for ablation performed at 30° incident angle. Surface enhanced Raman spectra (SERS) of Rhodamine 6G from nanostructured substrates were investigated using excitation wavelengths of 532 and 785 nm. In both the cases substrates prepared at 30° incident angle exhibited superior enhancement in the Raman signatures with a best enhancement factor achieved being >10{sup 8}. SERS of an explosive molecule 5-amino, 3-nitro, -1H-1,2,4-nitrozole (ANTA) was also demonstrated from these nanostructured substrates. Multiple usage of Ag nanostructures for SERS studies revealed that structures prepared at 30° incident angle provided superior performance amongst all.

Effect of polonium alpha-radiation on aqueous solutions (the history of French and Russian studies)

Since Pierre and Marie Curie's discovery of polonium and radium the effect of their radiation on chemical systems was noted. This gave rise to a new science - radiation chemistry. Systematic studies of radiation effects go back to the mid-1940s. The effect of gamma and x radiation was studied most, while only M. Curie's laboratory in France was concerned with alpha emitting polonium and radon. M. Haissinsky, M. Lefort, P. Bonet-Marry, M. Anta pioneered this activity. Radon was soon abandoned in favour of polonium recovered from RaD. With its short half-life, polonium is an ideal emitter which at its low content by weight produces a highly intensive radiation. French scientists determined radiation yields of H 2 , O 2 , H 2 O 2 and that of water radiolytic decomposition, G[-H 2 O]. The latter was found to be equal to 3.5 molecule/100 eV and much less than that from gamma radiolysis (4.2 molecule/100 eV). It should be noted that the polonium recovered from RaD contained a variety of impurities influencing the yield of radiolysis products formed. From the outset of her study in 1957, the author of this paper used the purest polonium recovered from reactor-irradiated Bi-209. This made it possible to define the yields from alpha radiolysis of various aqueous solutions more exactly. Relying on the J. Pucheault hypothesis concerning the decomposition of molecular radiolysis products in heavy particle tracks, author's efforts were directed toward the quantification of initial radiolysis yields. Special experiments have shown that G[-H 2 O] is much the same from alpha and gamma radiolysis (around 4.2 molecule/100eV). The author had the good luck to discuss her results with Pr. M. Haissinsky from Laboratory Curie. (author)

Sua casca tem sido utilizada medicinalmente a partir da exploração de árvores em populações naturais. O objetivo deste trabalho foi a realização de estudos de biologia reprodutiva de Drimys brasiliensis visando fundamentar estratégias de exploração sustentável e conservação, possibilitando a geração de renda a partir da exploração deste recurso florestal não madeireiro. Foram realizados estudos de fenologia reprodutiva (296 árvores acompanhadas por 30 meses, ecologia de polinização e dispersão de sementes, e biologia floral. O período de florescimento ocorre durante o verão, com pico em janeiro. Frutos verdes estão presentes o ano inteiro, amadurecendo com o aumento das temperaturas. Ocorre uma sobreposição das fenofases fruto verde e fruto maduro oriundas de florescimentos de anos diferentes. Com isso, frutos maduros estão disponíveis o ano inteiro para a fauna. Os himenópteros são os visitantes florais com maior potencial de fluxo gênico via pólen, porém, a sua frequência é baixa, assim como a dos demais visitantes, apesar da alta produção de flores e da alta viabilidade dos grãos de pólen. Com isso, a alta produção de frutos observada é possivelmente decorrente da autofecundação. Os dispersores primários de frutos são raros, tendo sido observados pássaros. Entretanto, a dispersão secundária das sementes que chegam ao solo por barocoria é alta.

Full Text Available This paper presents the hydrogeological and hydrochemical characterization of the unconfined aquifer located in the alteration mantle in the volcanic rocks from Serra Geral Formation, in the northeast region of Rio Grande do Sul State. This aquifer is conditioned by the soil, topography, lithology and climate, being characterized by a saturated layer thinner than 1,7 m, static levels between 0 and 1 m and low flow (<0,5 m3/h. These waters are of calcium or magnesium bicarbonate type, and low alkalinity and electrical conductivity, low calcium, magnesium, sodium, potassium and chloride concentrations, and high iron and manganese concentrations. Additionally, these waters have high concentration of nitrates (mean above 10 mg/L and the presence of total coliforms. These characteristics evidence a quick circulation between the recharging and discharge zones in the aquifer.

Establishing the credibility of archaeoastronomical sites

Ruggles, Clive L. N.

This is not a talk about archaeoastronomy per se, but rather about how the Astronomy and World Heritage Initiative helps us deal with archaeoastronomical sites as potential World Heritage.In 2011, an attempt to nominate a prehistoric “observatory” site onto the World Heritage List proved unsuccessful because UNESCO rejected the interpretation as statistically and archaeologically unproven. The case highlights an issue at the heart of archaeoastronomical methodology and interpretation: the mere existence of astronomical alignments in ancient sites does not prove that they were important to those who constructed and used the sites, let alone giving us insights into their likely significance and meaning. Advances in archaeoastronomy over several decades have resulted in the development of a substantial body of theory and practice (Ruggles 2014) where the most favoured interpretations depend upon integrating methods from astronomy, anthropology and other disciplines, but individual cases can still engender considerable controversy.The fact that more archaeoastronomical sites are now appearing on national tentative lists prior to their WHL nomination means that this is no longer just an academic issue; establishing the credibility of the archaeoastronomical interpretations is crucial to any assessment of their value in heritage terms.In this talk I shall describe progress that has been made within the Astronomy and World Heritage Initiative towards establishing broadly acceptable measures of archaeoastronomical credibility that make sense in the context of the heritage evaluation process. I will focus particularly, but not exclusively, on sites that are included in the Thematic Studies and/or are already included on national Tentative Lists, such as the Portuguese/Spanish seven-stone antas (Neolithic dolmens) and Chankillo in Peru (solar observation device dating to c. 300BC). I will also mention how the recognition of astronomical attributes of potential

På grunn av detlave prisnivået for alkohol er ulovlig import eller hjemmeproduksjon av alkohol ukjent på Svalbard. Dessutener samfunnet lite og oversiktlig, slik at det er praktisk mulig å undersøke hele befolkningen. I den aktuellestudien registrerte vi alt salg av alkohol til fastboende nordmenn på Svalbard i oktober og november 1988. Isamme tidsperiode ble alle nordmenn 18 år eller eldre invitert til å ta del i en helseundersøkelse der det inngikkspørsmål om alkoholbruk.

No counterfeit production or illegal import exists, thus making a complete registrationof all sources of alcohol possible. In this study we recorded sales from all agencies selling alcohol onSvalbard over a two month period in 1988. During the same period all adults living permanently on Svalbardwere invited to take part in a health screening. As part of the screening a self-administered questionnaire onalcohol consumption was introduced to the participants. We found that the self-reported volume accounted forapproximately 40 percent of the sales volume. Because of the unique situation applying to Svalbard, theestimate made in this study is believed to be more reliable compared to other studies using sales volume tovalidate self-reports.

The uranium mining site of Pocos de Caldas consists of open mine pit, tailings, waste rock dumps and an acid rock drainage problem, which has the potential to impact upon freshwater of the Ribeirao das Antas catchment. The high level of manganese (value of 1.8 mg/L) contained in the discharge water (DW) is an important factor affecting the water quality of the river (water quality criterion for aquatic life for Mn is 0.1 mg/L). Water quality criteria (WQC) are used for regulatory purpose and intended to define concentrations of chemicals in water that are protective of aquatic life and human health. WQC is a standard, although it is recognized that in some instances these criteria may be overprotective as metal bioavailability and hence toxicity is dependent on water chemistry. The toxicity assessment of WD was performed by bioassays with Daphnia similis and Ceriodaphnia dubia as bioindicators. As DW showed no toxicity to the organisms and the chemical analysis and dose assessments pointed U and Mn as the most important metals for water toxicity, the U and Mn toxicities were evaluated in the DW spiked with U and Mn. Acute uranium toxicity (48 h immobilisation test) for Daphnia similis was determined as a LC50 value (concentration that is toxic to 50% of test organisms) around 0.05-0.06 mg/L, value close to the one found for effects on reproduction, a 7 day LOEC (lowest observed effect concentration) of 0.062 mg/L for Ceriodaphnia dubia. The value of NOEC (no-observed effect concentration) for U was 0.03 mg U/L, which is higher than the concentration corresponded to the authorized dose limit for 238 U (0.004 mg/L) and higher than the uranium WQC (0.02 mg U/L). The manganese concentration in the DW is lower than the found value of LC50 (11.5 mg/L), LOEC (10 mg/L) and NOEC (5 mg Mn/L). (author)

Full Text Available Resumen Las aventuras gráficas, antaño uno de los géneros más relevantes de la industria del videojuego, parecen ya no tener cabida en una época de grandes presupuestos y tecnología puntera. Los juegos de acción, el rol online y las propuestas multijugador han desplazado un tipo de juego más centrado en el descubrimiento narrativo, los diálogos y el juego individual. No obstante, el reciente éxito de propuestas como The Walking Dead ha colocado el género, otra vez, en el centro de atención. En este contexto y lejos de la industria masiva del ocio electrónico emerge Resonance, una aventura retro de baja producción que ha conseguido recuperar el gusto por el arte pixelado en los videojuegos y ha establecido nuevas coordenadas sobre la nostalgia y la mitificación de los géneros caídos. En esta investigación se analiza el uso de los componentes estéticos y el diseño del mundo ludoficcional para reivindicar, una vez más, el drama simbólico construido desde la aventura gráfica tradicional. Abstract Graphic adventure games, once one of the most important genres of the video game industry, seem to have no place in an era of big budgets and cuttingedge technology. Action games, online RPG products and multiplayer games have taken the place of a type of game more focused on narrative, dialogues and individual play. However, the recent success of the game The Walking Dead placed again this game genre in the spotlight. In this context and quite far away from the massive electronic entertainment industry emerges Resonance, a low production retro adventure that has brought the taste for video games pixel art and has set new coordinates on nostalgia and the myth of the fallen genre.

An integrated research project of environmental sciences focuses on a group of four Andosol profiles in Western flank of the Peruvian southern Andes. Aim of this study is to contribute to the reconstruction of the paleo environmental conditions in the Western Cordillera of the Peruvian Andes. Standard pedological and sedimentological analysis has been conducted in order to identify morphological and geochemical features generated by climatic variations during the middle and late Holocene. Though a provenance analysis of sediments, all potential lithological sources around the town of Laramate are being examined under the scanning electron microscope, in order to find significant mineralogical associations downward the soil-profile. Preliminary results reveal two edaphic cycles within a soil-paleo soil-sequence: a relative poor developed "Ah" topsoil, mostly composed by fine grain sediments, is underlain by a well preserved "2Ah" paleo soil; a "2Bwt" subsoil exhibits signs of alteration and clay translocation; parent material in slight weathered statement at "2C" culminates the sequence. Mineralogical analytical data supports the premise, that materials in the uppermost horizons are relatable to distal geological units of the Western and Eastern Cordillera, therefore also related to other described aeolian archives from the region: "Desert Margin Loess" at the Andean foot-zone and "Mixed Loess" in the Puna grassland. The amphibole varieties Actinolite, Mg-Hornblende and Edenite could be only distinguished within the soil sediments. The fluvial transport to its current position is excluded, insofar mentioned varieties stem from the granodiorites of Coastal Batholite (downstream the study area), and the vulcanites of the Anta und Andahuaylas Formation (eastward the continental divide).

Brazil holds most of the Atlantic Forest Domain and is also one of the Rubiaceae diversity centers in the Neotropics. Despite the urban expansion in the state of Rio de Janeiro, large areas of continuous vegetation with high connectivity degree can still be found. Recently, new Rubiaceae species have been described in the Rio de Janeiro flora, which present small populations and very particular distribution. The current paper analyzed the similarity in the floristic composition of the Rubiaceae in eight Atlantic Forest remnants of Rio de Janeiro state protected by Conservation Units. We also surveyed and set guidelines for conservation of microendemic species. The similarity analysis were based on previously published studies in Área de Proteção Ambiental de Grumari, Área de Proteção Ambiental Palmares, Parque Estadual da Serra da Tiririca, Parque Nacional do Itatiaia, Parque Nacional de Jurubatiba, Reserva Biológica de Poço das Antas, Reserva Biológica do Tinguá and Reserva Ecológica de Macaé de Cima - using the PAST software (“Paleontological Statistics”) with Sørensen coefficient. The floristic similarity analysis revealed two groups with distinct physiographic characteristics and different vegetation types. Group A consisted in two Restinga areas, Área de Proteção Ambiental de Grumari and Parque Nacional de Jurubatiba, which showed strong bootstrap support (98 %). Group B included forest remnants with distinct phytophisiognomies or altitudes, but with moderate bootstrap support. Low similarity levels among the eight areas were found due to the habitats’ heterogeneity. The current study pointed out 19 microendemic species from the Atlantic Forest, they present a single-site distribution or a distribution restricted to Mountain and Metropolitan regions of Rio de Janeiro state. Concerning the conservation status of microendemic species, discrepancies between the Catalogue of Flora of Rio de Janeiro and the Red Book of Brazilian Flora (two of

Area-wide pest management of locusts and grasshoppers: The striking similarities of problems and solutions in Africa and the United States

Grasshoppers and locusts are among the most devastating pests of human agriculture. These insects cause serious damage to crops and forage on every arable continent, and their depredations have become the basis for legends, myths, and (in recent times) complex political and economic programmes. No pest problem spans such immense areas, with up to 8 million ha treated for rangeland grasshoppers during outbreaks in the US and 16 million km 2 prone to outbreaks of the Desert locust, Schistocerca gregaria Forskal, alone. The traditional management approach has involved extensive, regionalised control programmes, but recent trends suggest a decentralised future for grasshopper and locust management. Hence, we have a dynamic situation that presents the opportunity for a comparative analysis of the costs and benefits of an area-wide approach to pest management at different scales. As political, cultural, and communication barriers between scientists dissolve, the possibility of learning from one another's experiences (both failures and successes) promises to dramatically accelerate the rate of innovation, progress and discovery in pest management. For example, the recent advances in Reduced Agent-Area Treatments (RAAT, in which insecticide is applied to swaths, separated by untreated swaths or buffers) for management of rangeland grasshoppers in the US (Lockwood and Schell 1997) are based on the adaptation of tactics developed by African, Australian, Asian, and European scientists (Rachadi and Foucart 1996, Musuna and Mugisha 1997, Scherer and Celestin 1997, Wilps and Diop 1997, Launois and Rachadi 1997). The key to successful adaptation of management methods must begin with intellectual modesty and nationalistic humility so that the insights of non-scientists and experts from outside one's country are given respect and serious consideration. It is subsequently necessary to recognise the essential similarities and differences between land use systems and understand the

Specify epidemioclinical and legal aspects of sexual abuse among minors and evaluate the cost of care in Dakar. This is a retrospective multicenter cross-sectional study on sexual abuse among minors over a period of four years from 1st January 2006 to 31st December 2009. Four maternities were targeted: the Social Hygiene Institute of Medina, health center Roi-Baudouin Guédiawaye, the Pikine hospital and health center Youssou-Mbargane-Diop of Rufisque. During the study period, 252 child victims of sexual abuse were supported at four health facilities on a total of 272 sexual abuses of all ages, a frequency of 92.64%. The epidemiological profile of our patients was a child of 11 years old on average, female (100%) and living in the suburbs of Dakar (68.1%). Children were often abused during working hours (31.7%), outside the family environment and often by someone known to the victim (72.6%). Genito-genital contact was the most common mode of sexual contact (80.9%) with vaginal penetration in 61% of cases. Almost all of the victims (92.1%) came to consult, accompanied by their parents, between the 1st and 4th day after the sexual abuse (70%). The examination usually revealed a hymenal trauma (59.9%) of which nearly half (49%) consisted of old lesions. 56.9% of victims had a post-traumatic stress disorder and 31.1%, mutism. We recorded six (6) pregnancies, 2% of our sample. A case of HIV infection was recorded on a sample taken 72hours after sexual abuse. Control of three months HIV serology was requested in 7.1% of cases and only 20% of children had received antiretroviral prophylaxis. Antibiotic prophylaxis had been performed in 13.7% of cases using doxycycline as drug of choice (75%). Only 29% of our patients had received emergency contraception progestin and psychological care concerned only 22% of children. On the legal aspects, 46% of our patients had filed a complaint. Prosecutions were 38%, 45% of which were convicted and 21% were acquitted. The rate of

This pollution mainly derives from road traffic emissions with, in some capitals (e.g. Cotonou), the strong contribution of two-wheel vehicles. Two key questions arise: are presently available emission inventories (e.g. Junker, C., Liousse, C., 2008.

The aim of this paper is to develop a methodology to estimate emissions produced by two-wheel vehicles in West Africa for 2002 in a context where reliable information is hardly available. Fuel consumption ratios between two-wheel engines (in this work) and all vehicles issued from UN database ( http://data.un.org/Data.aspx?d=EDATA&f=cmID%3aMO%3btrID%3a1221) are as high as 169%, 264% and 628%, for Burkina Faso, Mali and Chad respectively, indicating that this global

Full Text Available O estudo objetivou avaliar a riqueza e composição de vertebrados de médio e grande porte em latrinas ativas e inativas de ariranhas [Pteronura brasiliensis (Gmelin, 1788], em uma Unidade de Conservação de Uso Sustentável na Amazônia Oriental Brasileira. O estudo foi realizado em 45 latrinas ao longo de 230 km nos rios Falsino e Araguari (0°55'N, 51°35'W, sendo que desse total, 24 apresentaram fezes frescas e 21 fezes velhas de ariranhas. De julho a novembro de 2012, cada latrina foi monitorada com uma armadilha fotográfica programada para operar por 24 horas. O esforço de campo resultou em 458,8 armadilhas/dia, sendo 247,5 armadilhas/dia em latrinas com fezes frescas e 211,3 armadilhas/dia com fezes velhas. Foram obtidos registros de 22 espécies de vertebrados. A maior parte das espécies registradas foram mamíferos (n = 13, seguida por aves (n = 6, e répteis (n = 3. As espécies mais frequentemente fotografadas foram paca [Cuniculus paca (Linnaeus, 1766; n = 21], jaguatirica [Leopardus pardalis (Linnaeus, 1758; n =11], juriti-pupu (Leptotila verreauxi Bonaparte, 1855; n = 8, ariranha [Pteronura brasiliensis (Gmelin, 1788; n = 7], e anta [Tapirus terrestris (Linnaeus, 1758; n = 6], que foram responsáveis por 55,8% de todos os registros. A maior parte dos registros (69,5% foram obtidos em latrinas com fezes frescas e o número de espécies foi maior (n = 19 do que os registrados em latrinas com fezes velhas (n = 15. No entanto, a dissimilaridade entre a comunidade de vertebrados entre latrinas com fezes frescas e velhas não diferiu. A média de visitação em latrinas com fezes frescas foi ligeiramente superior do que em latrinas com fezes velhas, embora essa diferença tenha sido apenas marginalmente significativa. Entretanto, houve uma diminuição no número de registros de felinos [Leopardus pardalis, Leopardus wiedii (Schinz, 1821 e Panthera onca (Linnaeus, 1758], marginalmente significativo em latrinas com fezes frescas

Full Text Available La petición de cantidades extraordinarias de dinero bajo la denominación de donativos, para atender a los gatos derivados sobre todo del mantenimiento de las tropas durante las campañas militares y el abastecimiento de la Armada, fue una costumbre puesta en práctica a partir del reinado de Felipe II y continuada por sus sucesores. En el reinado de Carlos II se quiso suavizar la presión fiscal, eliminando las peticiones extraordinarias de dinero. Pero cuando surgían los conflictos bélicos el único recurso posible era el donativo, pues el resto de las cantidades recaudadas estaban ya empeñadas en otros menesteres. La ciudad de Sevilla, que se había caracterizado por la generosidad de los donativos ofrecidos al rey, no disponía ya durante la época de Carlos II del poder económico de antaño y tenía grandes dificultades para recaudar las cantidades ofrecidas y hacer frente al mismo tiempo a los donativos del reinado anterior aún pendientes, ya que los arbitrios que se imponían no daban el fruto apetecido. Por lo tanto, al final del siglo xvii no quedó otra solución que la de limitar al máximo esta forma de contribución extraordinaria a la Monarquía.The request for an extra amount of money, called donativo, in order to meet the expenses originated by the maintenance of troops during military campaigns and the suppiying of the Navy, was a practice held from Philipp ITs reign and continued by his sucessors. In Charles II's reign, a lessening of tax pression was intended, by means of removing the requests of extra money. But, in the occasion of war conflicts, the only possible resources were the donativos, because the other taxes had been already used for other needs. Seville, which would stand out for the generosity of its donativos, had not the same economic power as in past times, and was in great trouble to collect the money for the new and the oíd financial help granted to the king, because the taxes did not produce the

In distances less than 100m from the dolmens, it is possible to identify an outcrop with equal features (petrographic as well geometric) with those found in the slabs. These observations agrees with previous authors (e.g. Boaventura, 2000) that favours a pragmatic attitude of Neolithic populations in the search of the appropriate slabs for construction.

Full Text Available En el espacio de integración de la Unión Europea persisten las fronteras, ya sin las dificultades y barreras de antaño, pero manteniendo numerosos símbolos y elementos del patrimonio cultural que siguen marcando una diferencia. Son líneas divisorias y, a la vez, franjas de territorios de transición con un importante patrimonio natural y cultural que se convierten ahora en recursos de atracción para novedosas demandas turísticas. Por ello, se estudia ya el turismo de frontera como un nuevo producto donde el recurso de la frontera y la historia es el principal atractivo y destino, aunque de forma complementaria a otros recursos y productos turísticos. Al margen de otros territorios y destinos fronterizos de Europa o del mundo, nuestra preocupación investigadora se centra en la Raya luso-española, en su extremo sur, en el Bajo Guadiana, en espacios que participan del Algarve, Baixo Alentejo y Huelva.

and 2·7 g/L (SD 17·8) in the oxytocin group. When adjusted for cluster design, the mean difference in haemoglobin decreases between groups was not significant (0·3 g/L, 95% CI -8·26 to 8·92, p=0·71). Both drugs were well tolerated. Shivering was common in the misoprostol group, and nausea in the oxytocin group. Postpartum haemorrhage was diagnosed in one woman allocated to oxytocin, who was referred and transferred to a higher-level facility for additional care, and fully recovered. No other women were transferred. In terms of effects on haemoglobin concentrations, neither oxytocin nor misoprostol was significantly better than the other, and both drugs were safe and efficacious when delivered by auxiliary midwives. The programmatic limitations of oxytocin, including short shelf life outside the cold chain, mean that misoprostol could be more appropriate for community-level prophylaxis of postpartum haemorrhage.

Full text: A national project of food irradiation in the country is being proposed. At present there are no facilities for food irradiation (and food irradiation research) in Kenya. This report is therefore largely comparative between the traditional and the conventional food preservation methods on the one hand and the irradiation technique on the other. The report is also based on information from other countries where food irradiation is practiced (Kawabata, 1981) or is being also contemplated (Diop et al, 1997), as well as on the relevant report of the International Atomic Energy Agency (IAEA) on this topic (IAEA, 1993). The paper presents the statement of the research problem, i.e., in Kenya large quantities of food and other farm produces go to waste annually as a result of the inadequacies of the preservation techniques currently in use. These (other) preservation techniques, although often less controversial than the irradiation techniques, have also been found to be more expensive to run when compared to irradiation techniques. Such techniques, presently employed in Kenya, include the traditional methods (e.g. sun drying, smoke and fire drying, etc.) and modern techniques such as freezing or refrigeration, lyophilization, etc., as well as application of chemicals like insecticides and fumigants. The latter combines the disadvantages of high costs with environmental pollution and associated health risks. In this preliminary research, aimed at studying the prospects of a national food irradiation project, the following food items that are selected for their importance to the economy of the country, include potatoes, rice, maize, coffee, tea, various fruits, fish and meat. The paper also explores the economic feasibility as well as the human and technological requirements of establishing a commercial food irradiation plant, with aim of assessing the applicability of food irradiation as alternative or a complimentary approach for preservation technique in

Ocio, tiempo libre y empleo

Full Text Available La propuesta de la Modernidad pretende que del trabajo, la sociedad derive el bienestar y la vida feliz. El trabajo informado como empleo proporciona seguridad, opciones, posibilidades, valores, bienes, riqueza, felicidad. Una visión bien distinta a la de la Grecia Clásica, inspiradora de la democracia de Occidente, que hace poner en duda la paradoja moderna del trabajo y del tiempo libre bajo todas sus institucionalizaciones, unas generadas culturalmente por las sociedades avanzadas, otras provenientes de la tradición lúdica heredada por el siglo de la Revolución Industrial (turismo, deporte, vacaciones, fiestas, carnavales, actividades de tiempo libre, ocio. Cabe entonces preguntarse si en los inicios de la nueva era postmoderna, de la que somos protagonistas, ocurre que el trabajo y el tiempo libre vienen generando un nuevo sentido, en donde ya no aparecen como irreconciliables opuestos, ni con tajante relación de subordinación. Lo cierto es que hoy, un buen sector del pensamiento sobre la lúdica se inclina por afirmar que se está produciendo una revolución/evolución del trabajo, del empleo y del tiempo libre que los relaciona de modo distinto, acercándolos al punto de compartir entre sí nuevas y cambiantes visiones. Este texto hace parte de esa actualidad del pensamiento. Sostiene que parece haberse superado la simple apuesta teórica de cambio en la tríada binomio trabajo/ empleo/tiempo libre, pues se aprecia un efectivo cambio de rumbo al concretarse una nueva visión de felicidad y de uso del tiempo libre, ya no ligada exclusivamente con la satisfacción de las necesidades materiales, ya no amparada en el binomio histórico esclavo/amo, ya no producto exclusivo del trabajo en su visión de antaño, ya no ansiosa de excesos y banalidades, y a la vez, se aprecia el inicio del cambio hacia un trabajo que ya no es empleo privativo de la libertad, que se llena de lúdica, dejando de ser único imperativo de la vida.

Objetivo. Realizar la caracterización epidemiológico-molecular de 20 aislamientos de Enterobacter cloacae resistentes a cefalosporinas de tercera generación; provenientes de un hospital de tercer nivel de Bogotá-Colombia. Material y métodos. Los aislamientos fueron identificados mediante sistemas automatizados Microscan y VITEK, se utilizó el Enterobacter asbureae como control externo inter-especie. La confirmación de resistencia se hizo por técnica de difusión en agar, y una vez establecida se realizó BLEE para comprobación. La determinación de puntos isoeléctricos se hizo, mediante lisis por ultrasonido y la genotipificación mediante la metodología para bacterias Gramnegativas propuesta por Versalovic. Resultados: Los aislamientos colectados durante un año fueron causantes de 15 casos de infección Intrahospitalaria y dos colonizaciones. Todos los aislamientos presentaron resistencia a cefotaxima, ceftazidima, ceftriaxona, aztreonam y ciprofloxacina, 95% a amikacina, gentamicina y cloranfenicol, 75% a trimetoprim/sulfametoxazol, 20% a cefepime y todos fueron sensibles a imipenem.

The humble in a context of "greatness": challenges facing the regeneration of Barrio Antiguo in Monterrey, Nuevo Leon

Full Text Available The current “Barrio Antiguo” (Old Quarter of Monterrey (Mexico, formerly known as "Cathedral Quarter", is a postmodern product arising from the intervention between 1988 and 1994 in a sector called First Square, shortly after the construction of the “Macroplaza” (1979-1985 destroyed a significant part of that same sector. Thus, “Barrio Antiguo” became an example of consciousness cleansing experience. The area is a part of what would become the center of Monterrey, whose physical and conceptual boundaries are still undefined. After a harsh period of degradation in the quarter, especially profound in the context of organized crime and its resulting violence in recent years, the Municipal Institute for Planning and Coexistence of Monterrey (IMPLANC has undertaken the task of regenerating the area. The aim of this lecture is to reveal the difficulties faced by the previously mentioned regeneration, starting with the "inferiority complex" that stirs up among the Monterrey population –traditionally-identified with the official discourse of "greatness"– due to the humility of both the architecture and the vernacular northeastern atmosphere of the quarter, especially when comparisons are made with national historic centers which are World Heritage Sites. El actual Barrio Antiguo de Monterrey, antaño conocido como “Barrio de Catedral”, es un producto posmoderno que surge de la intervención realizada entre 1988 y 1994 en un sector del llamado Primer Cuadro de la ciudad, poco después de que las obras de la Macroplaza (1979-85 destruyeran una parte importante de ese mismo sector. Barrio Antiguo vino a ser así una especie de lavado de conciencia. La zona es una parte de lo que sería el centro histórico de Monterrey, cuyos límites físicos y conceptuales aún están sin definir. Después de una dura etapa de degradación del Barrio, especialmente intensa en el contexto de la ola de violencia de los últimos años, el Instituto

Full Text Available La transgression est sans doute constitutive de toute littérature, mais, dans le cas des littératures de l’Afrique subsaharienne, sa représentation apparaît selon deux modalités principales. D’un côté, la transgression de lois, d’usages et d’interdits à l’intérieur de la société pré-coloniale, qui sera illustrée par une analyse du conte de Birago Diop, Petit-mari et du roman de Chinua Achebe, Things Fall Apart ; de l’autre, la transgression, dans le cadre de la situation coloniale, de lois ou d’interdits édictés par le colonisateur, comme on le verra à partir de quelques exemples empruntés aux romans de Mongo Beti et de F. Oyono. On constatera par ailleurs que la transgression qui s’opère dans le contexte colonial est parfois plus difficile à repérer qu’on ne peut le penser de prime abord, dans la mesure où elle ne s’opère pas nécessairement de manière frontale, puisqu’elle utilise les failles, les interstices ou les contradictions du système de domination mis en place. C’est dans cette perspective qu’il faut situer les nombreuses œuvres retraçant le parcours effectué par un sujet africain pour s ‘approprier le savoir que lui refuse le colonisateur : L’enfant noir de Camara Laye, Tell Freedom de Peter Abrahams, Down Second Avenue de Mphahlele, Amkoullel l’enfant peul de Hampâté Bâ. - Au terme de l’exposé, on tentera de préciser si les littératures africaines constituent un cas spécifique dans cette représentation de la transgression ou si, au contraire, elles s’inscrivent dans un processus général que l’on retrouve dans n’importe quelle littérature.Transgression is the central phenomenon in any literature. But, in African literature, writers actually describe two kinds of transgression. On the one hand, transgression of taboos, uses and laws inside the pre-colonial societies, as we can observe, for instance, in Birago Diop’s tale Petit-mari or in Chinua Achebe�

We analyzed data from 78 sample units (AU installed in the remnants of SDF between 2008 and 2009 by professional team of Floristic and Forest Inventory of Santa Catarina project (IFFSC. The data were processed through the Detrended Correspondence Analysis (DCA and Canonical Correspondence Analysis (CCA, using a matrix of species density associated with a environmental variables matrix, that consisted of altitude and climate parameters. The proportion of variance explained by the first three axes of DCA was low, accounting for approximately 21% of the information contained in the original data set. This result provides low power of interpretation of the results. However, when DCA was applied to the data of mean density of species in each river basin, the results pointed to better explanatory eigenvectors (three first eigenvectors explain 58.1% of total variance. The first ordination axis of DCA grouped the eastern watersheds SUs at one end, and the western watersheds SUs at the other end of this axis.

Summativ vurdering i formativ drakt – elevperspektiv på tilbakemelding fra heldagsprøver i norsk

Full Text Available Denne artikkelen handler om hvordan elever på ungdomstrinnet forstår og bruker skriftlige lærerkommentarer på heldagsprøvebesvarelser i norsk. Slike kommentarer gis ofte på sluttprodukter. I vurderingsforskning antas tilbakemelding på sluttprodukter å ha begrenset verdi som læring, og med denne studien ønsker jeg å se om en slik generell antakelse gjelder også i en norskfaglig kontekst. Det empiriske materiale består av elevtekster med lærerkommentarer, verbale protokoller og individuelle elevintervju for 18 elever. Verbale protokoller brukes for å studere elevenes forståelse av lærerkommentarene, og intervju brukes for å få dypere innsikt i hvordan elevene bruker kommentarene. Studien viser at elevene har liten bevissthet rundt vurderingskriterier. Men de leser vurderingene og viser i hovedsak adekvat forståelse av kommentarene de får. Når det gjelder oppfølging av kommentarene, gjør elevene det som blir forventet av dem. Noen av elevene må «rette» tekstene sine, mens andre er ikke forventet å gjøre noe med kommentarene. Dette gjør at elevene i liten grad bruker kommentarene videre i skrivearbeidet. Mens enkelte internasjonale studier rapporterer om at studenter i høyere utdanning ikke leser tilbakemeldingene (Hounsell, 1987 eller ikke forstår dem (Lea & Street, 1998, viser mitt materiale at elevene leser og forstår kommentarene, og de gjør det som forventes av dem i oppfølgingen.

Delta 99, de Carlos Giménez, y el semanario Trinca son los ejemplos más significados de una renovación que entonces se inicia y que dará sus mejores frutos en la década siguiente.

Denne artikkelen vil rette oppmerksomheten på mulige årsaker til dette, og hvorfor restaurantkokker vurderer å endre arbeidsplass eller yrkesmulighet. Restaurantbransjen er i rask utvikling og befolkningen spiser stadig oftere på restaurant (Bugge & Lavik, 2007. Samtidig synker rekruteringen til kokkeyrket (Sundquist, 2016. Det er derfor viktig å drøfte hvilke faktorer som har betydning for at restaurantkokker forlater yrket etter forholdsvis kort tid.Problemstillingen er; Hvorfor vurderer så mange kokker å skifte yrke når de er så stolte av yrket sitt?I denne artikkelen er det gjennomført en reanalyse av grunnlagsmaterialet som ble presentert i rapporten «Yrkesutøvelse i restaurant og matfagene – Arbeidsoppgaver, prioriteringer og forskjeller» (Spetalen, Eben & Jahnlu, 2016. I tillegg til denne univariate analysen har jeg også sammenliknet gjennomsnitt og testet hypoteser ved hjelp av T-test og ANOVA i SPSS (Johannessen, 2009; Pallant, 2013.  Studenter ved bachelorutdanningen i Restaurant og matfag, kull 2013 ved Høgskolen i Oslo og Akershus, tok utgangspunkt i dataene fra Spetalen et al. (2016 i sine bacheloroppgaver. I samarbeid med tre studenter er det gjennomført kvalitative intervjuer med til sammen 23 nåværende og tidligere kokker. For å forklare dataene har jeg trukket inn det organisasjonsteoretiske begrepet «turnover» siden dette er et tydelig problem i restaurantbransjen. Faktorer som tiltrekker og frastøter medarbeideren i forhold til yrket, er også med i diskusjonen for å forklare funnene (Lashley, 2000; Brochs-Haukedal, 2010; Kuvås, 2013.

ådet kring Ammarnäs genomfördes under åren 2001- 2005 ett fältexperiment för att uppskatta nedbrytningshastigheten av renspillning. Under tre somrar lades totalt 382 renspillningar ut i hägn i tre olika typer av habitat (fjällhed, fjällbjörkskog och granskog. Det visade sig att nedbrytningshastigheten var långsammast på fjällheden, där spillningshögarna fortfarande var kvar efter fyra år. Den exponentiella nedbrytningshastigheten beräknades till -0.027 högar/vecka om nedbrytningen antas ske under barmarksperioden. I skogshägnen gick nedbrytningen snabbare och alla högar var borta inom två år. Vid spillningsinventeringar på kalfjällsområdet eller områden med liknande marktyp, där syftet är att studera djurens habitatval över en längre tid rekommenderas att använda den så kallade ”faecal accumulation rate”-metoden, där man inventerar orensade ytor. Det ger en generell bild av hur djuren använt området under en längre period, eftersom nedbrytningen av spillning är långsam i sådana habitat.

éculo 19 com azulejos produzidos em Portugal e Alemanha que já apresentam distintos graus de degradação. O Palacete Pinho é uma das mais importantes destas edificações e foi selecionado para se investigar a ação do clima tropical amazônico sobre a degradação destes azulejos. Para atingir estes objetivos mapearam-se os azulejos desta edificação visando identificar as modificações de origem orgânica e inorgânica e coletas de amostras para análises. Os minerais foram determinados por DRX, a composição química por métodos clássicos úmidos e MEV/SED e os micro-organismos por microscopia. Os resultados obtidos mostram que os azulejos Portugueses e Alemães são distintos entre si. Enquanto o biscoito é composto de SiO2 e Al2O3, CaO foi encontrado apenas nos Portugueses. Os baixos conteúdos de Na2O e K2O indicam adição de materiais para redução da temperatura de fusão. SiO2 e PbO compõem o vidrado, já CoO e FeO foram adicionados como pigmentos. O biscoito dos azulejos Alemães é constituído de quartzo, mullita e cristobalita, ao contrário do Português com quartzo, gehlenita, diopsídio, calcita e feldspatos. Os vidrados são amorfos ao DRX. As diferenças químicas e mineralógicas entre os azulejos Portugueses e Alemães indicam que foram produzidos por matéria prima distinta, bem como processo termal. As alterações relacionadas com o intemperismo são as finas camadas de detritos (nos Alemães, manchas de oxidação, manchas escuras, descolamento do azulejo (no Português; perda de vidrado e biscoito tornando-se pulverulento como consequência do estabelecimento de Cyanophyta e bacillariophyta (Português. As distintas feições de degradação dos azulejos refletem as suas diferenças mineralógicas e químicas expostas ao clima tropical Amazônico.

; adicionalmente, ele contém rochas ricas em mica, foscoritos e lamprófiros. Fenitos também ocorrem e estão representados principalmente por quartzitos e xistos proterozóicos do Grupo Araxá. O estudo petrográfico de 130 amostras de testemunhos de sondagem indica que o complexo reúne basicamente dois tipos litológicos, carbonatitos e rochas ricas em mica, e, subordinadamente, um terceiro de composição híbrida. Carbonatitos apresentam composição química variável e têm magnésiocarbonatitos como o tipo mais abundante. Dolomita e calcita são os seus principais constituintes, mas outras fases carbonáticas, incluindo as pertencentes ao grupo dos carbonatos ricos em ETR, são também reconhecidas. Fosfatos e óxidos diversos caracterizam os acessórios mais comuns enquanto que os minerais silicáticos consistem de representantes dos grupos da olivina, clinopiroxênio, mica e anfibólio. As rochas ricas em mica reúnem abundantes glimmeritos e escassos piroxenitos cumuláticos portadores de quantidades variáveis de flogopita, olivina e diopsídio. As rochas híbridas contêm principalmente flogopita e tetraferriflogopita, respectivamente, como fases cumulus e intercumulus; minerais carbonáticos podem também estar presentes. Dados químicos indicam que os carbonatitos são fortemente enriquecidos em ETR e possuem teores mais baixos em Nb, Zr, V, Cr, Ni e Rb em relação às rochas mais ricas em mica. As concentrações mais altas em K, Nb e Zr dessas últimas poderiam ser atribuídas a processos metassomáticos (glimeritização que teriam afetado os piroxenitos. O comportamento similar dos ETR nos carbonatitos e nas rochas ricas em mica parece sugestivo de que essas litologias estão relacionadas a um mesmo magma parental, possivelmente de composição ijolítica. O pronunciado fracionamento ETRL/ETRP e os elevados teores em ETR de algumas amostras de carbonatitos poderiam estar ligados a processos de natureza hidrotermal ou mesmo supergênicos.

sociales. Los armenios, ellos mismos, preocupados por no atizar las peleas de antaño y deseosos de presentar un interlocutor único ante las autoridades, hicieron una concesión al «mito de la unidad». Por consiguiente, cabe preguntarse si ese olvido del papel desempeñado por los comunistas, no corresponde a la suerte reservada a la fracción de los «vencidos» que, durante decenios, se opuso a la Independencia de Armenia.If the name Manouchian, immortalized by the “L’Affiche rouge” (“The Red Poster”, echoes well beyond the Armenian community, few amongst Armenians themselves actually know Manouchian’s story, or that of his comrades, in interwar France. The fact that a part of the Armenian “colony” in France participated in the Communist movement is often ignored. In her recent book on the Armenians of Vienne (Isère, Anahide Ter Minassian asserts that amongst the “Viennese workers […], Armenian communists where influent before, after, and during the Second World War”. However, how can one explain that none of the works concerning Armenians in France investigate this phenomenon in detail? It seems that the Armenian community is often perceived as a homogeneous group, without social or political dissent. Armenians themselves, anxious not to revive past conflicts, and to offer the powers to be a single interlocutor, have given in to this “myth of unity”. But wouldn’t one be tempted to see, in this oblivion of the role of Communists, the fate reserved to the “defeated”, those who during decades where hostile to the independence of Armenia?

mirar el inmenso horizonte que se abre ante sus ojos invoca el pensamiento de Platón, fundador de la Academia, quien hace mas de 20 siglos, sin contar con las fabulosas metodologías científicas que hoy nos apoyan, sostenia que:

“El conocimiento surge de dos componentes fundamentales: La percepción y el concepto. La percepción es aquella que se adquiere directamente mediante los sentidos, la cual es necesariamente imperfecta dada la limitación de los organos que la originan. De esta percepción de origen físico surge el pensamiento y de este el concepto y la idea.

La idea surgida en esta forma tampoco puede ser un concepto perfecto, pues depende en gran parte de la percepción, de los fenómenos que rodean al sujeto y de su capacidad de entendimiento, de acuerdo con su cultura y esta influida necesariamente por el medio que lo rodea. Lo que antaño era idea buena como el sacrificio humano a los dioses o la esclavitud, ha evolucionado con la difusión y mejor conocimiento de las leyes que rigen el universo, con el enorme progreso de las técnicas científicas, con su divulgación cada vez mas universal a traves de la informática. Cómo comparar el conocimiento y por tanto las ideas de un hombre del común de la época de Platón, con el que puede tener un sujeto cualquiera en nuestros días...

Full Text Available La mecánica de las estructuras de fábrica ha sido durante mucho tiempo de alguna manera abandonada en la enseñanza universitaria durante la licenciatura de arquitectura, en comparación con otros campos del conocimiento, como el hormigón armado, el acero y la madera. Una parte importante de nuestro patrimonio arquitectónico se erigió empleando estas técnicas ampliamente difundidas antaño, pero ahora olvidadas tanto en la práctica constructiva como en el marco teórico de la universidad, más centrado en tecnologías contemporáneas e innovadoras. Los avances del software computacional como son los modelos macro/micro de elementos finitos nos permiten realizar un análisis extremadamente complejo de estructuras de mampostería, pero paradójicamente, al mismo tiempo, se distancian de las limitaciones y la forma en que los antiguos concibieron y entendieron la arquitectura. Los maestros canteros fueron capaces de construir perfectamente sin la ayuda de tales pruebas precisas sobre los materiales. Por lo tanto, la mentalidad que hay que adoptar a la hora de abordar la enseñanza del comportamiento de las estructuras de mampostería es aquella en la que se estimule al alumnado a apropiarse del conocimiento no solo de la geometría, sino también y principalmente de las fases del proceso constructivo y de las técnicas acordes al período histórico. Solo una vez elaboradas ciertas hipótesis sobre ellas, se deberá comenzar con el cálculo gráfico-numérico. El objetivo del presente trabajo es exponer una metodología de enseñanza basada en programas de optimización y ejemplificada con el estudio de un caso concreto: el análisis de las arquerías de la Mezquita de Córdoba y de los posibles sistemas de contrarresto provisionales de empujes mediante tirantes y apeos, buscando la rentabilidad material de los mismos.

Las Facultades de Medicina son entidades docentes formadoras de médicos, una de cuyas funciones es la de modelar y estructurar sólidos cimientos éticos en sus alumnos.

Al respecto, algunos médicos desinformados han llegado a creer erróneamente que los Tribunales de Etica Médica son algo así como instrumentos inquisitorios de represión para los profesionales de la medicina, cuando justamente podríamos calificarlos como guardianes de su integridad moral y laboral, siempre que se haya ejercido la profesión ajustándose a las normas de la pericia, la prudencia y la diligencia.

Lo que ocurre es que vivimos hoy en una sociedad donde impera la desconfianza frente al médico y al cirujano socializados, estimulada por abogados en trance de honorarios, aseguradoras, reguladores de gastos evaluadores de riesgos, que han surgido como consecuencia de la progresiva implantación de la medicina social, tanto oficial como privada con criterio comercial, conocida ésta última como medicina prepagada.

Esta nueva modalidad del ejercicio de la medicina y la cirugía, ha debilitado la relación médico-paciente basada en la confianza recíproca que antaño existía entre los dos elementos humanos que intervienen en el acto médico.

Si a lo anterior se agrega la abundante información de los pacientes y sus allegados, a través de todos los medios publicitarios, sobre las nuevas tecnologías y adelantos maravillosos en el diagnóstico y tratamiento de las distintas enfermedades, que los hacen desear una atención basada en lo mejor y más avanzado y con la dedicación y el afecto del médico privado, se comprende el hecho de que un buen número de pacientes y familiares instauren demandas contra su médico tratante.

Es entonces cuando el Tribunal de Etica Médica, con serenidad y absoluta imparcialidad, califica después de un detenido y ponderado estudio de cada expediente, el grado de la falta cuando existe, con criterio

los tiempos, a la que tanta importancia daba Platón, padre de la Academia, en Atenas, quien enseñó en ella entre los años 360 y 347 a. de e, después de ser discípulo afortunado de Sócrates, y siendo a su
vez maestro de Aristóteles, quien merecería el honroso título de “Maestro de los que saben”.

Es precisamente Platón quien en su Teeteto, primer libro conocido sobre psicología o el funcionamiento de la mente, divide el “conocimiento” en dos componentes fundamentales: la percepción y el concepto.

Percepción es aquello que se adquiere directamente mediante los sentidos, la cual es necesariamente imperfecta dada la limitación de los órganos que la originan. De esta percepción, de origen físico, surge el pensamiento y de éste el concepto y la idea.

Conceptos son la justicia; el valor; la templanza; la virtud.

La idea tampoco puede ser un concepto perfecto pues depende en gran parte de la percepción, del medio que rodea al sujeto, de su capacidad de entendimiento de acuerdo con su cultura; de su evolución genética diríamos hoy.

y así, la idea no puede ser estática, debe evolucionar a través de los siglos. Lo que antaño era una idea buena, como el sacrificio humano a los dioses o la esclavitud, ha evolucionado con la difusión y mejor conocimiento de la leyes que rigen el universo, con el enorme progreso de las técnicas científicas, con su divulgación cada vez más universal a través de la informática. ¿Cómo comparar el conocimiento y por tanto las ideas de un hombre del común de la época de Platón, con el que puede tener un sujeto cualquiera en nuestros días?

Ese concepto platónico de que las ideas no significan conocimiento perfecto y que el hombre debe seguir evolucionando en busca de la luz, es el que hace que la Academia exista hoy y deba existir mañana y el próximo siglo y el próximo milenio y el de más allá, y deberá seguir evolucionando y aprendiendo y enseñando y sobre

Desde que la medicina se tornó curativa con los bacteriostáticos y antibióticos, hace 70 años, la humanidad doliente entró en una nueva fase que aún vivimos y que pudiera denominarse la edad del medicamento. Hasta entonces los medicamentos no pasaban de ser sintomáticos aunque algunos, como los analgésicos, anestésicos, sedantes y otros, como los digitálicos y los derivados naturales o sintéticos de la quina, habían sentado ya sus reales en una terapéutica que, siglo y medio atrás, era tan primitiva que había hecho exclamar a Voltaire cuando se enteró que un sobrino suyo pensaba estudiar medicina: “Desgraciado, ¡cómo te atreves a estudiar un arte que consiste en administrar venenos que no conoces a organismos que todavía conoces menos!”. El siglo XX, como nos lo recuerda Alfredo Jácome Roca en este ameno libro, introdujo de lleno la farmacología como una ciencia que, a su vez tomó sus raíces en la fisiopatología, la química, la bacteriología y la inmunología que habían abierto la era de la “medicina etiopatológica”, al decir de Laín Entralgo, medicina que aún se perpetúa en nuestros días.

Toda esa evolución del pensamiento médico, desde una terapia empírica, animista y mágica en el primitivo hombre de antaño hasta la terapéutica molecular y casi atómica de hogaño, está amenamente descrita en este libro, dividido en una introducción general y seis secciones o capítulos rematados por un séptimo o addendum que sirve a su vez de resumen o colofón de los anteriores. En todos ellos logra el autor darnos una visión panorámica de la historia de la terapéutica que es, a su vez, la historia de la medicina, pues ésta se estableció, desde las culturas más primitivas, como un arte para curar la enfermedad. La cual ha estado presente, según ha sido demostrado, desde el Neanderthal hasta nuestras calendas. Al fin y al cabo, como lo dijera Juan Montalvo, el notable polígrafo ecuatoriano, �

Cada familia nuclear tenía por lo general tres hijos. 10. Como todo grupo humano de cultura marginal, que no conformaban Estados políticamente organizados, fueron unos eximios amantes de la libertad, y para defenderla peleaban valerosamente. Sus armas fueron lanzas, macanas, dardos, tiraderas, escudos de madera y pellejo de anta. También confeccionaron puñales de hueso. En la nación de Bagua, aguerridamente combatían hombres y mujeres en las batallas. 11. Todos estos grupos étnicos, desde 1549 fueron repartidos en forma de encomiendas, y por consiguiente entregados a varios españoles que conquistaron y se apoderaron de los territorios dé Jaén. 12. La invasión europea originó en ellos un grave trastorno psicológico y biológico. El trabajo obligatorio y forzado en los lavaderos de oro, la imposición del tributo de corte medieval, más el sarampión y la viruela, poco a poco acabaron diezmándolos. Si en 1549 se hallaron entre ellos 20.000 tributarios, para 1606 habían mermado a 1500. Pero en el siglo XIX desaparecieron casi por completo. Los dos últimos huambucos murieron en el pueblo de Santa Rosa, hace aproximadamente doce años. 13. La documentación etnohistórica existente no permite adentrarnos en otros detalles de la cultura espiritual y material de las etnías de la cuenca del Chuquimayo. Consecuentemente, nada más podemos decir de su estructura familiar, de la vida social de los individuos, de su organización política, de su economía, de sus rituales y creencias, de sus conocimientos y tradiciones, etc. etc. Solamente por analogía con otros grupos del mismo estadio cultural podríamos llegar a un conocimiento más amplio acerca de ellos.
