El complejo cultural de la Edad de los Metales en Europa. Análisis a través de los testimonios de objetos del Bronce Final hasta la Segunda Edad del Hierro.

Dissetenes Jornades de Foment de la Investigació de la FCHS (Any 2012)Gracias a la arqueología, la prehistoria se ha documentado de una serie de elementos para investigar épocas pasadas carentes de escritura. La industria lítica y más tarde la madera y el marfil serán los objetos estudiados en las primeras culturas de la humanidad. Con la llegada de la metalurgia, los objetos se vuelven más complejos, más imperecederos y muestran a su vez la serie de cambios producidos en las sociedades tanto a nivel económico como cultural o social. Será por tanto en estos objetos en los que se centrará el estudio de las sociedades metalúrgicas partiendo de ocho figuras representativas de las culturas que se desarrollan en Europa. A partir de una punta de lanza se desarrollará la cultura del Bronce Antiguo y Medio en el Norte de Europa. Los carros de culto del Bronce Final servirán para analizar la cultura de los Campos de Urnas de Centroeuropa. La cultura Villanoviana, Hallstat y el horizonte orientalizante que tuvieron lugar durante la Primera Edad del Hierro se estudiarán a partir de un carro de Bisenzio, el diván del príncipe de Hochdorf, la urna de Sopron y la sítula Benvenuti. Por último, la cultura de La Tène de la Segunda Edad del Hierro se investigará partiendo de una serie de fíbulas así como el espejo Holcombe.Thanks to archeology , prehistory has been documented in a number of elements to investigate past devoid of writing. The lithic industry and later wood and ivory objects will studied in the early cultures of humanity. With the arrival of the metallurgy, objects become more complex, more enduring and turn show the number of changes in both societies economically and culturally or socially. It will therefore be these objects in the study of metallurgical companies will focus based eight representative figures of the cultures that develop in Europe . From a spearhead culture will develop And Middle Bronze Age in Northern Europe. The cult of cars Bronze Final will be used to analyze the culture of urnfields Central Europe. The Villanovan , Hallstatt culture and skyline orientalizante that took place during the First Iron Age be studied from a shopping Bisenzio, Prince of the couch Hochdorf , urn of Sopron and Benvenuti situla . Finally , the culture of Second La Tène Iron Age will be investigated starting from a series of brooches and Holcombe mirror

Avoidance and contextual learning induced by a kairomone, a pheromone and a common odorant in female CD1 mice

Chemosignals mediate both intra- and inter-specific communication in most mammals. Pheromones elicit stereotyped reactions in conspecifics, whereas kairomones provoke a reaction in an allospecific animal. For instance, predator kairomones elicit anticipated defensive responses in preys. The aim of this work was to test the behavioral responses of female mice to two chemosignals: 2-heptanone (2-HP), a putative alarm pheromone, and 2,4,5-trimethylthiazoline (TMT), a fox-derived putative kairomone, widely used to investigate fear and anxiety in rodents. The banana-like odorant isoamyl acetate (IA), unlikely to act as a chemosignal, served as a control odorant. We first presented increasing amounts of these odorants in consecutive days, in a test box in which mice could explore or avoid them. Female mice avoided the highest amounts of all three compounds, with TMT and IA eliciting avoidance at lower amounts (3.8 pmol and 0.35 μmol, respectively) than 2-HP (35 μmol). All three compounds induced minimal effects in global locomotion and immobility in this set up. Further, mice detected 3.5 pmol of TMT and IA in a habituation–dishabituation test, so avoidance of IA started well beyond the detection threshold. Finally, both TMT and IA, but not 2-HP, induced conditioned place avoidance and increased immobility in the neutral compartment during a contextual memory test. These data suggest that intense odors can induce contextual learning irrespective of their putative biological significance. Our results support that synthetic predator-related compounds (like TMT) or other intense odorants are useful to investigate the neurobiological basis of emotional behaviors in rodents. Since intense odorants unlikely to act as chemosignals can elicit similar behavioral reactions than chemosignals, we stress the importance of using behavioral measures in combination with other physiological (e.g., hormonal levels) or neural measures (e.g., immediate early gene expression) to establish the ethological significance of odorants

Cidade Litoral Proposta de expansão urbana para a Ribeira Grande de Santiago

A ilha de Santiago, Cabo Verde, sofreu uma reestruturação administrativa em 2005 e foi constituído o concelho da Ribeira Grande. Sendo um concelho recente, foi elaborado em 2010 o Plano Director Municipal, tendo em vista a expansão da sua área urbana e consolidação de as diversas localidades espalhadas. Neste concelho encontra-se inserida a Cidade Velha, centro histórico e patrimonial, apresentando-se como o poder administrativo local, abarcando diversas problemáticas quer a nível social quer a nível espacial. Esta dissertação pretende reflectir sobre o modelo de expansão proposto para a concepção da Cidade Nova do PDM, com base em factores inerentes ao lugar, fazendo também uma abordagem ao tema do património e o seu papel na Ribeira Grande

Estudo da qualidade acústica em auditórios

As condições acústicas de um espaço devem proporcionar um ambiente sonoro adequado às atividades que aí são desenvolvidas, especialmente nos locais destinados à palavra, como por exemplo em salas de aula. O objetivo deste trabalho é o estudo da qualidade acústica, em especial a qualidade da audição da palavra durante as aulas, de quatro auditórios de uma instituição de ensino superior. Para a realização deste estudo foram selecionados auditórios com diferentes características, tendo-se realizado medições e análises do tempo de reverberação nos referidos ambientes para identificar os principais problemas existentes a nível da acústica de salas. Para além da avaliação ?in situ? do tempo de reverberação dos auditórios estudados, fez-se a avaliação subjetiva dos mesmos baseada em inquéritos aos alunos e professores que os frequentam.info:eu-repo/semantics/publishedVersio

Association between tumor-infiltrating limphocytes and sentinel lymph node positivity in thin melanoma

Abstract: Background: Sentinel lymph node biopsy in thin invasive primary cutaneous melanoma (up to 1mm thick) is a controversial subject. The presence of tumor-infiltrating lymphocytes could be a factor to be considered in the decision to perform this procedure. Objective: To evaluate the association between the presence of tumor-infiltrating lymphocytes and lymph node metastases caused by thin primary cutaneous melanoma. Methods: Cross-sectional study with 137 records of thin invasive primary cutaneous melanoma submitted to sentinel lymph node biopsy from 2003 to 2015. The clinical variables considered were age, sex and topography of the lesion. The histopathological variables assessed were: tumor-infiltrating lymphocytes, melanoma subtype, Breslow thickness, Clark levels, number of mitoses per mm², ulceration, regression and satellitosis. Univariate analyzes and logistic regression tests were performed as well the odds ratio and statistical relevance was considered when p <0.05. Results: Among the 137 cases of thin primary cutaneous melanoma submitted to sentinel lymph node biopsy, 10 (7.3%) had metastatic involvement. Ulceration on histopathology was positively associated with the presence of metastatic lymph node, with odds ratio =12.8 (2.77-59.4 95% CI, p=0.001). The presence of moderate/marked tumor-infiltrating lymphocytes was shown to be a protective factor for the presence of metastatic lymph node, with OR=0.20 (0.05-0.72 95% CI, p=0.014). The other variables - clinical and histopathological - were not associated with the outcome. Study limitations: The relatively small number of positive sentinel lymph node biopsy may explain such an expressive association of ulceration with metastatization. Conclusions: In patients with thin invasive primary cutaneous melanoma, few or absent tumor-infiltrating lymphocytes, as well as ulceration, represent independent risk factors for lymph node metastasis

Sex pheromones are not always attractive: changes induced by learning and illness in mice

A male-specific major urinary protein named darcin is attractive to female mice, Mus musculus, stimulates a learned attraction to volatile components of a male's urinary odour and induces spatial learning. In this article we show that darcin also induces learned attraction for a previously neutral olfactory stimulus (the odorant isoamyl acetate), acquired by repeated presentation of both stimuli together. We hypothesize that this is a case of olfactory–vomeronasal associative learning, in which darcin acts as the unconditioned reinforcer. However, the presence of darcin is not always attractive to adult female mice. Urine from males parasitized by the nematode Aspiculuris tetraptera has no attractive value for females, despite apparently normal presence of darcin. The loss of attractive value may be due to unknown infection-derived chemicals whose detection overrides the attraction induced by darcin, or prevents detection of darcin by other (unknown) mechanisms. Other cases in which male urine (and thus the presence of darcin) does not induce attraction are discussed, namely in lactating females, which respond with aggression towards intruder males, and in prepubertal females, which show aversive responses towards unfamiliar male urine. Thus, although the darcin sex pheromone induces attraction in adult female mice that does not need to be learned, such innate pheromonal responses can be modulated by the physiological or health status of the sender and receiver. This provides a degree of flexibility in response to pheromonal signals, but such that individuals of the same class or status still share consistent predictable responses to improve their reproductive fitness. Further, by readily inducing the same response towards other odorants through associative learning, pheromones can also target responses flexibly towards odour signatures at an individual-specific level

PROEJA e o significado socioeconômico da inserção do jovem no mercado de trabalho

O presente artigo ora aqui anunciado é resultado de pesquisa realizada na cidade de São Vicente do Sul, RS, e tem a intenção de mostrar a importância de agregar aos currículos do curso de PROEJA, disciplinas que dêem atenção especial ao tema empreendedorismo. Busca, também, esclarecer o tema e demonstrar a importância do mesmo, como um elemento agregador de valor, no sucesso de uma futura carreira profissional. Sabemos que o mercado formal de trabalho, o qual dá certas garantias ao trabalhador, como férias, carteira assinada, fundo de garantia, décimo terceiro salário, entre outros, encontra-se em fraca decadência, pois a cada ano que passa, diminui o número de vagas oferecidas. Assim, é preciso buscar alternativas que supram a demanda de trabalhadores que pretendem realizar seus projetos. Os resultados apontam para essa necessidade. Palavras-chave: PROEJA. Mundo do trabalho. Empreendedorismo
