COBRADORES PÓS-MODERNOS

The analysis of the short stories “O Cobrador” and “Onze deMaio” (O Cobrador, 1979), of Rubem Fonseca (1925 -), it demonstrates that the postmodernism became an intellectual movement questioner of the social differences. Fonseca's work approaches, with clarity, the disorder, the disaggregation, the absence of defined values, the social crisis and the physical and mental violence, found in the Brazilian cities. The incorporationof the means of mass communication in the narrative is good to evidence the difference of the social strata, besides exercising influence in the suffered violence and caused by the characters.A análise dos contos “O Cobrador” e “Onze de Maio” (O Cobrador, 1979), de Rubem Fonseca (1925 - ), demonstra que o pósmodernismo se transformou em um movimento intelectual de questionamento dos desnivelamentos sociais.

Novel Scintillating Materials Based on Phenyl-Polysiloxane for Neutron Detection and Monitoring

Neutron detectors are extensively used at many nuclear research facilities across Europe. Their application range covers many topics in basic and applied nuclear research: in nuclear structure and reaction dynamics (reaction reconstruction and decay studies); in nuclear astrophysics (neutron emission probabilities); in nuclear technology (nuclear data measurements and in-core/off-core monitors); in nuclear medicine (radiation monitors, dosimeters); in materials science (neutron imaging techniques); in homeland security applications (fissile materials investigation and cargo inspection). Liquid scintillators, widely used at present, have however some drawbacks given by toxicity, flammability, volatility and sensitivity to oxygen that limit their duration and quality. Even plastic scintillators are not satisfactory because they have low radiation hardness and low thermal stability. Moreover organic solvents may affect their optical properties due to crazing. In order to overcome these problems, phenyl-polysiloxane based scintillators have been recently developed at Legnaro National Laboratory. This new solution showed very good chemical and thermal stability and high radiation hardness. The results on the different samples performance will be presented, paying special attention to a characterization comparison between synthesized phenyl containing polysiloxane resins where a Pt catalyst has been used and a scintillating material obtained by condensation reaction, where tin based compounds are used as catalysts. Different structural arrangements as a result of different substituents on the main chain have been investigated by High Resolution X-Ray Diffraction, while the effect of improved optical transmittance on the scintillation yield has been elucidated by a combination of excitation/fluorescence measurements and scintillation yield under exposure to alpha and {\gamma}-rays.Comment: InterM 2013 - International Multidisciplinary Microscopy Congres

La socialisation différenciée de genre en crèche: l'influence de l'aménagement de l'espace

Ce mémoire est une étude comparative de deux crèches du Valais romand qui s’intéresse à la socialisation différenciée de genre. Mon but a été de découvrir si l’aménagement de l’espace a une influence sur le comportement stéréotypé des enfants. Je vais tenter de répondre à ma question de départ qui est la suivante : « Comment l’aménagement de l’espace au sein d’une crèche influence la socialisation différenciée de genre auprès des enfants âgés de 3-4 ans ? ». Pour ce faire, je vais effectuer deux entretiens auprès des responsables de structure et d’éducatrices de l’enfance travaillant au sein de la crèche, ainsi que des activités filmées auprès d’enfants

The relevance of citizen involvement in Health Technology Assessment. A concrete application in the assessment of HPV co-testing in the Autonomous Province of Trento

Background Specific programs have been developed in the latest decades to involve patients in Health Technology Assessments (HTAs). However, there are no structured practises in Italy and citizen’ perspective is rarely included in HTA reports. Aim of this study is to explore citizen’ opinions about cervical cancer screening with Human Papillomavirus (HPV) co-testing in the Autonomous Province of Trento (PAT). Methods Two focus groups were conducted: one with representatives of patients’ associations, the other one with women between 31 and 64 years and their family members. Following aspects were investigated: the importance of cervical cancer screening programs; the impact of HPV test on women’ and their partners’ life; needs, expectations, and critical aspects of the new screening method. Results Organised screening programs are very important for all participants. HPV co-testing screening is preferred to cytology for its higher sensitivity, but different opinions came out regarding the longer screening interval after normal HPV and Pap test results. Citizen stressed that correct, clear, and unambiguous information have to be provided to the whole population (men included). A cardinal role plays the patient-doctor relationship in informing and taking care, also emotionally, of women, their partners and relatives in case of positive HPV test. Conclusion In order to facilitate the introduction of the new screening method, various media must be used to spread clear and unambiguous information, as well as informative and educational meetings with doctors and caregivers. Citizen perspective was included in the report for the Health Trust and played an important role in the decision process

A violência social em contos de Rubem Fonseca

O presente artigo propõe analisar como se dá a representação da violência social nos contos “Onze de Maio” e “Anjos das Marquises” de Rubem Fonseca, o qual é um dos maiores escritores brasileiros a versar sobre violência e vozes marginalizadas. Para tal, buscou-se analisar a relação entre violência e literatura, além de discutir questões referentes às representações sociais acerca de indivíduos marginalizados no Brasil. Ao se observar a violência tão presente na sociedade brasileira, torna-se importante analisar como ela tem sido representada na literatura, a qual pode, através da desautomatização da percepção, levar a uma reflexão sobre o estado atual

Investigation of corrosion-erosion phenomena in the primary cooling system of SPIDER

SPIDER dedicated cooling plant has to remove up to 10 MW thermal power from in-vessel components and auxiliary systems. The circuit is characterized by three main heat transfer systems: primary, secondary and tertiary systems. The primary system is made of four circuits, with only three operating so far, these are called PC01, PC02 and PC03. These three circuits respectively cool SPIDER power supplies and the beam source components using ultrapure water. During 2019 SPIDER experimental campaigns, it was observed that electrical resistivity of water degraded considerably and more quickly (∼25 MΩ cm h−1 in PC01) than estimated by design. To overcome this issue, water had to be restored very frequently to maintain the desired characteristics and avoid possible detrimental leakage currents throughout the circuit. The reason for this severe water degradation has to be better understood before issues such as abrupt failures may arise. This work presents a preliminary analysis of the two main circuits (PC01 and PC02) where an estimation of water degradation induced by general corrosion of stainless steels and copper components was made. This preliminary estimation showed that PC01 could be more prone to general corrosion than PC02; however, the rate of water conductivity increase was 5.3 times smaller than that observed during experiments in 2019 and 2020

Blockchain and Cryptocurrencies: a Classification and Comparison of Architecture Drivers

Blockchain is a decentralized transaction and data management solution, the technological leap behind the success of Bitcoin and other cryptocurrencies. As the variety of existing blockchains and distributed ledgers continues to increase, adopters should focus on selecting the solution that best fits their needs and the requirements of their decentralized applications, rather than developing yet another blockchain from scratch. In this paper we present a conceptual framework to aid software architects, developers, and decision makers to adopt the right blockchain technology. The framework exposes the interrelation between technological decisions and architectural features, capturing the knowledge from existing academic literature, industrial products, technical forums/blogs, and experts' feedback. We empirically show the applicability of our framework by dissecting the platforms behind Bitcoin and other top 10 cryptocurrencies, aided by a focus group with researchers and industry practitioners. Then, we leverage the framework together with key notions of the Architectural Tradeoff Analysis Method (ATAM) to analyze four real-world blockchain case studies from industry and academia. Results shown that applying our framework leads to a deeper understanding of the architectural tradeoffs, allowing to assess technologies more objectively and select the one that best fit developers needs, ultimately cutting costs, reducing time-to-market and accelerating return on investment.Comment: Accepted for publication at journal Concurrency and Computation: Practice and Experience.
