Knowledge and attitudes of official inspectors at slaughterhouses in southern Brazil regarding animal welfare

Abstract: We assessed the views, knowledge, and attitudes of livestock inspectors working in federally inspected slaughterhouses in southern Brazil, the major pig and poultry processors in the country, regarding farm animal behavior and welfare, and factors that may influence animal welfare improvements at abattoirs. An online questionnaire with closed and open questions was sent to all the federally inspected slaughterhouses in the three states of the region. All respondents (n = 83) strongly agreed that animals are capable of feeling [...]

Inquérito soroepidemiológico para brucelose em suídeos do Brasil

Abstract: Porcine brucellosis is an infectious disease characterized by abort, infertility and increased mortality of weaned piglets In this study, using random sampling, 3027 swine herds from three management systems of 13 Brazilian states were evaluated for presence of antibodies for Brucella spp using buffered Brucella antigen tests (BBAT) and 2 mercaptoethanol/slow serum agglutination test It was observed a high occurrence of reagent farms in the card test, but none were positive for Brucella spp in confirmatory tests (2ME)/slow serum agglutination test

Aspectos do sítio lítico boa esperança ii (interior paulista), ponderados pela interface com quadros geomórficos regionais e sua possível inserção no contexto da transição pleistoceno-holoceno

Abstract: RESUMO: O presente artigo traz uma apresentacao do sitio litico Boa Esperanca II (BES II), no segmento paulista do Planalto Brasileiro. Trata-se de um sitio litico instalado em baixos terracos fluviais de fundo de vale das Escarpas Cuestiformes do medio curso do rio Jacare-Guacu. Apresenta um acervo coletado de quase 2 mil pecas liticas, sendo interpretado como um assentamento de funcoes diversificadas e com ocupacao continua ou sucessiva. Alem disso, discute -se a possibilidade de inclui-lo entre os registros arqueologicos brasileiros inseridos no contexto da transicao P leistoceno- H oloceno. Neste trabalho, aborda mos o sitio com base em sua insercao nos quadros fisico-ambientais regionais – com enfase para a interface com quadros de relevo e sucessoes cronomorfologicas estimadas – e analises tecnotipologicas. Observamos na s correlacoes entre o acervo de pecas liticas, quadros geomorficos e dados de datacao de fotoluminescencia opticamente estimulada em nivel arqueologico elementos que permitem consider a -lo como um novo sitio arqueologico, no interior paulista, a integrar o intervalo temporal destacado . As implicacoes referentes a extensao da antiguidade da ocupacao humana e o fato de apenas uma datacao de fotoluminescencia ter sido divulgada, levam porem a destacar a necessidade de novos, mais densos e diversificados estudos antes de dar como certa a insercao do sitio BES II no intervalo do periodo paleoindio proximal ao limite entre as duas mais recentes epocas geologicas. ABSTRACT: This article makes a presentation of the lithic site Boa Esperanca II (BES II), in the Sao Paulo segment of the Brazilian Plateau. It is a lithic site installed in low fluvial terraces of valley bottom of the Cuestiformes Scarps that take place on the middle course of the Jacare-Guacu river. It presents a collection of almost 2 thousand lythic pieces, being interpreted as a possible settlement of diversified functions and with continuous and / or successive occupation. It gathers elements that take us to consider the possibility of including it among the Brazilian sites inserted in the context of the Pleistocene-Holocene transition. This article approaches the site based on its insertion in the regional physical-environmental frameworks - with emphasis on the presence of relief pictures in the physical landscape - and techno-typological analyzes. We observed in the interface of the collection of lithic pieces, geomorphic frames and dating data of optically stimulated photoluminescence at the archaeological level elements that allow us to consider it as a possible new archaeological site to integrate the previously mentioned temporal period. The archaeological implications of the issue, and the fact that only a dating of photoluminescence has been disclosed, nevertheless point out the need for new, denser and more diversified studies.

Some applications of fusion reactions with zinc chloride in inorganic spot test analysis

Abstract: Anhydrous hydrogen chloride, which is far more reactive than concentrated aqueous hydrochloric acid, is formed when solid zinc chloride or evaporation residues of its solutions are heated. Certain reactions, which cannot be accomplished with the concentrated aqueous acid, can be realized by fusion with zinc chloride. Detection of calcium, magnesium, ferrous iron, nickel, and potassium in silicates; differentiation of niobium and tantalum pentoxides, can be based on the ready decomposition of silicates and on a redox reaction of niobium pentoxide. Fusion with zinc chloride can release ferrous iron from acid-resistant minerals that contain no silica. All of these processes can be accomplished with slight amounts of sample and within the technique of spot test analysis.
