Identidades e diferenças: o caso da guerra civil na antiga Iugoslávia

Abstract: The civil war in the former Yugoslavia (1991 - 1995) had a strong ethnicreligious component. In an attempt to maintain the cohesion of an artificially created state post-first World War, identities were sought and accepted - and institutionalized - the differences between the various peoples that constituted the "land of the South Slavs". From the 1980s the differences were highlighted during the war and taken to the extreme, especially in the territories of Croatia and BosniaHerzegovina. From literature and the author's personal experience and using concepts of culture, ethnicity, identity, difference, belonging, nation and state, the text shows how the ethnic-religious differences were used during the civil war in Yugoslavia to claim possession of territories, strengthen discourse of the impossibility of coexistence, overvalue potential threats and fear and justify the perpetration of crimes against humanity.

Carbon Film Coating of Abutment Surfaces: Effect on the Abutment Screw Removal Torque

Purpose: To evaluate the effect of diamond-like carbon (DLC) coating of prefabricated implant abutment on screw removal torque (RT) before and after mechanical cycling (MC).Materials and Methods: Fifty-four abutments for external-hex implants were divided among 6 groups (n = 9): S, straight abutment (control); SC, straight coated abutment; SCy, straight abutment and MC; SCCy, straight coated abutment and MC; ACy, angled abutment and MC; and ACCy, angled coated abutment and MC. The abutments were attached to the implants by a titanium screw. RT values were measured and registered. Data (in Newton centimeter) were analyzed with analysis of variance and Dunnet test (alpha = 0.05).Results: RT values were significantly affected by MC (P = 0.001) and the interaction between DLC coating and MC (P = 0.038). SCy and ACy showed the lowest RT values, statistically different from the control. The abutment coated groups had no statistical difference compared with the control. Scanning electron microscopy analysis showed DLC film with a thickness of 3 mm uniformly coating the hexagonal abutment.Conclusion: DLC film deposited on the abutment can be used as an alternative procedure to reduce abutment screw loosening.

Estudo de parâmetros radiométricos e legislação sobre radioproteção em equipamentos de radiodiagnóstico

O uso de radiações ionizantes (R.I.), nas mais variadas atividades tem aumentado nas últimas décadas. Com o avanço tecnológico, novos e sofisticados equipamentos emissores de R.I. tem surgido no cenário nacional, o que torna imperativo a difusão do conhecimento sobre os conceitos de proteção radiológica junto à comunidade em geral, e neste sentido, o curso de física médica desenvolve um importante papel, quer seja no aspecto informativo quanto formativo de cidadãos e profissionais críticos e politicamente corretos, que possam contribuir com as Políticas Públicos dos órgãos normatizadores e fiscalizadores das atividades de vigilância sanitária. Conforme a legislação atual (Resolução SS-625 de 14/12/1994, da Secretaria de Estado da Saúde, e Portaria 453 de 01/06/1998 da Vigilância Sanitária do Ministério da Saúde), todos os serviços que utilizam radiações ionizantes devem realizar testes de avaliação dos parâmetros radiométricos dos equipamentos emissores de R.I., sendo exigidos as medidas de Levantamento Radiométrico das instalações, o Teste de Radiação de Fuga do cabeçote emissor e a implementação de Programa de Garantia de Qualidade dos equipamentos e dos procedimentos radiológicos. Este procedimento tem como objetivo principal a obtenção de imagens radiográficas com qualidade e a segurança de pacientes e profissionais, evitando a exposição desnecessária à radiação de pacientes e profissionais. A correta realização de procedimentos radiológicos além de reduzir a dose nos pacientes também promove significativa diminuição nos custos, por não haver necessidade da repetição dos exames. No Brasil, conforme dados da Secretaria de Atenção à Saúde SAS/MS, atualmente existem instalados 4.469 mamógrafos, 25.930 aparelhos de raios-x médicos, 39.438 aparelhos de raios-x odontológicos e...(Resumo completo, clicar acesso eletrônico abaixo)

A onomasiologia e seus dicionários: o caso do Dicionário onomasiológico de expressões cromáticas da fauna e flora

Nowadays, the lexicographical market has experienced an increase of the number of works produced. These works belong to two forms of macro-structural organization: the semasiological one and onomasiological one. This study aims at considering the qualities and advantages of onomasiological dictionaries, as well as defending that semasiology and onomasiology establish an intrinsic relationship that should be considered in the development of dictionaries. In order to demonstrate the benefits provided by a combination of onomasiological and semasiological courses in the same work, we describe how such courses were adopted in the Onomasiological Dictionary of Chromatic Phrases from Fauna and Flora.

Metas de inflação no Brasil (1999-2012): uma análise institucional

The paper shows the advantages and handicaps of implementing an inflation target (IT) regime, from post-keynesian and institutional stances. It is post-keynesian as long as it does not perceive any benefit in the mainstream split between monetary and fiscal policies. And it is institutional insofar as it shows there are several ways of implementing a policy, such that the chosen one is determined by historical factors, as illustrated by the Brazilian case. Thus, one could even support IT policies if their targets were seen just as “focusing devices” guiding economic policies, but also regarding with due attention other targets, as, in the short run, output growth and employment and, in the long run, technology and human development. Therefore, an IT is not necessary, although it can be admitted, mainly if the target is hidden from the public, in order to increase the flexibility of the central bank.

A coleta de corpus de aprendizes: questões qualitativas em uma pesquisa sobre a escrita de aprendizes de língua espanhola

In this paper we discuss and present the first results gathered from the compilation of a learner corpus comprised of texts written by university students (Language, Literature and Translation Course). We made use of Corpus Linguistics and observations of researchers from the learner’s corpus field, in order to compile and analyze a corpus of argumentative and descriptive texts written in Spanish. Four hundred compositions were collected (about 120 thousand words) from August 2011 to December 2012. The methodology adopted assisted us considerably in maintaining a comprehensive working agenda, taking into consideration students’ needs and using the data collected as subsidy to improve classroom management of content. We also present the difficulties faced during the data gathering and propose procedures do avoid or minimize them.

Efeito antimicrobiano e citotóxico do óleo essencial de Cymbopogon citratus sobre células odontoblastóides

The aim of this study was to evaluate the antimicrobial and cytotoxic effect of essential oil (EO) of lemon grass (Cymbopogon citratus). From the agar diffusion method, different concentrations of EO (0.135%, 0.2% and 1%), and control solutions (chlorhexidine (Chx), distilled water (Ad) and cereal alcohol (Ac)) were applied on cultures of Candida albicans (C.a), Streptococcus mutans (S.m), Streptococcus sobrinus (S.sob) and Lactobacillus acidophilus (L.a). For C.a, S.m and S.sob, the largest inhibition zones in descending order were: Chx, Ac and EO 1%, while the latter two were statistically similar (Mann-Whitney, p> 0.05). For L.a, the largest inhibition halo was observed for the Chx, followed by EO at 1%, 0.2%, 0.135% and Ac. For evaluation of cytotoxicity, the following groups were set: G1: 0,1% EO; G2: pure EO; G3 (positive control): H2 O2 ; G4: cereal alcohol; and G5 (negative control): culture medium – DMEM. The solutions were applied on the cultured MDPC-23 cells, which were plated (30,000 cells/cm2 ) in wells of 24 well-dishes. Cell metabolism was evaluated by MTT assay. Considering G5 (negative control) as 100% of cell metabolism, it was observed for G1, G2, G3 and G4 a percentage reduction in cell metabolism of 29.6%, 82%, 81.2% and 33.4%, respectively. It was concluded that the low concentration of 0,1% OE (C. citratus) was able to inhibit the growth of the strains tested as well as caused mild cytotoxicity to the cultured MDPC-23 cells.

Liming in Growing Mango Cultivar Keitt in Production

The tropical soil acidity is one of the main limiting factors for crop productivity. This study aimed to evaluate the effects of application of limestone dose to soil fertility, nutritional status of the crop, and productivity and quality of the fruits of mango, cultivar Keitt. The study was carried out at Selviria, state of Mato Grosso Sul, Brazil, in a Typic Haplustox (pH in CaCl2=4.7), cultivated with mango cultivar Keitt grafted on Coquinho pattern in the production phase (13years old). Treatments were composed of limestone doses (0, 1.55, 3.10, 4.65, and 6.20tha(-1)), arranged in blocks at random with three repetitions. The limestone was applied and incorporated in the surface layer of 0 to 5cm deep in the total area. We evaluated the chemical attributes of the soil [pH, hydrogen (H+) aluminum (Al), calcium (Ca), magnesium (Mg), potassium (K), and sum of bases and base saturation] at 16 and 28months after liming (layer 0 to 20cm deep), the nutrition of plants at 12months after liming, and quality of the fruit in two crop years. Liming promoted improvements in soil chemical attributes, reflected in the nutritional status, productivity, and quality of mango fruit. Also, there was a linear effect with the application of lime dose on the productivity of the fruit, but after the second year of evaluation.

Improvement of an enzyme immunosorbent assay for detecting antibodies against Dioctophyma renale

An available enzyme-linked immunosorbent assay (ELISA) was studied for the detection of anti-Dioctophyma renale antibodies in the sera of dogs using, detection of parasite eggs in urine sediment as a reference test. ELISA uses a soluble antigenic preparation of esophagus of D. renale and the optimal dilutions of the antigen, serum and conjugate were determined by means of checker board titration, using positive (n=13) and negative (n=27) reference serum. The specificity and sensitivity of the ELISA were 93.8% and 92.3% respectively and the kappa index was good (0.76). These results suggest that ELISA described may prove to be an effective serological test for detecting dogs infected and exposed to this parasite mainly dogs that are not eliminating parasite eggs through their urine.

Husserl's two notions of completeness: husserl and hilbert on completeness and imaginary elements in mathematics

In this paper I discuss Husserl's solution of the problem of imaginary elements in mathematics as presented in the drafts for two lectures he gave in Göttingen in 1901 and other related texts of the same period, a problem that had occupied Husserl since the beginning of 1890, when he was planning a never published sequel to Philosophie der Arithmetik (1891). In order to solve the problem of imaginary entities Husserl introduced, independently of Hilbert, two notions of completeness (definiteness in Husserl's terminology) for a formal axiomatic system. I present and discuss these notions here, establishing also parallels between Husserl's and Hilbert's notions of completeness. © 2000 Kluwer Academic Publishers.
