Um estudo exploratório sobre as práticas socio-ambientais de empresas multinacionales no setor de mineração do Peru

O presente trabalho tem por objetivo conhecer as práticas socio-ambientais no setor de mineração do Peru. Setor que esta dominada pela presença de empresas transnacionais que se encontram com duas realidades de regulamentação de meio ambientais muito discordantes, a primeira, as normas corporativas onde se encontra a matriz e, a segunda, a regulamentação do país onde esta a subsidiaria, neste caso o Peru. Com a internacionalização do tema socio-ambiental, se dá a devida importância ao tema da Responsabilidade Social Corporativa, já que as empresas transnacionais estão pressionadas a manter uma boa imagem internacional, que pode ser vulnerável a criticas negativas em relação à heterogeneidade, já que suas praticas socio-ambientais têm que ser as mesmas em qualquer parte do mundo. Na presente dissertação se enfatiza as praticas socio-ambientais das empresas com relação às comunidades circundantes, sendo um tema pouco difundido na mineração peruana. As desconformidades das comunidades frente aos projetos de mineração constituem o maior problema social atual, gerando a paralisação das atividades nesse setor. O Peru não tem Ministério do Meio Ambiente, embora exista um Conselho Nacional do Meio Ambiente (CONAM) que é um organismo público descentralizado e, esta aderido ao âmbito da Presidência do Conselho de Ministros. Nesta investigação se analisa a função do Ministério de Energia e Minas do Peru, já que ele é um ente que incentiva a promoção de investimento privada no setor de energia e minas e, por outro lado, mediante a Direção Geral de Assuntos Ambientais do Ministério de Energia e Minas aplica a guia de gestão ambiental emitidas pelo CONAM. Finalmente, no estudo de caso, são analisadas duas empresas transnacionais maiores do setor de mineração peruano, aplicando entrevistas e um questionário com perguntas abertas para poder conhecer suas praticas socio-ambientais. Desenvolve-se uma análise dos resultados obtidos no estudo de caso, utilizando o referencial teórico para situar a realidade peruana, numa realidade internacional. Pelos dados obtidos, podemos interpretar que as empresas estudadas não se encaixam totalmente nos parâmetros internacionais do auto-regulamentação. Observamos a falta de políticas públicas sócio-ambiental, é por esse motivo, a conclusão desta investigação propõe a criação e aplicação de políticas públicas a dois problemas socio-ambientais, o primeiro, a geração de emprego indireto e a segunda, a recuperação dos passivos ambientais.

The gyromagnetic factor of elementary particles and non-minimal coupling

In this work we investigate a possible magnetic moment generation for massive neutral particles with spins-1 and -2 coupled non-minimally, in a specific way, to an external electromagnetic field. It is found that, in the nonrelativistic limit, these particles present g = 1. This result, worked out in the framework of Relativistic Quantum Mechanics, seems to suggest that g = 1 for all massive and neutral particles of any spin ≤ 2. We also compare with the results obtained for massive charged particles of spins-1 and -2, in the same regime (nonrelativistic), in order to investigate the role played by the spin separetely from the charge.

Absence of Klein's paradox for massive spinless bosons coupled by a nonminimal vector interaction

A few properties of the nonminimal vector interaction in the Duffin-Kemmer-Petiau theory in the scalar sector are revised. In particular, it is shown that the nonminimal vector interaction has been erroneously applied to the description of elastic meson-nucleus scatterings and that the space component of the nonminimal vector interaction plays a peremptory role for the confinement of bosons whereas its time component contributes to the leakage. Scattering in a square step potential is used to show that Klein's paradox does not manifest in the case of a nonminimal vector coupling.

Heavy-quark symmetries in the light of nonperturbative QCD approaches

We critically review the validity of heavy-quark spin and flavor symmetries in heavy-light decay constants, form factors and effective couplings obtained within a nonperturbative framework, the ingredients of which are all motivated by Dyson-Schwinger equations studies of QCD. Along the way, we make new predictions for two effective nonphysical couplings: gDsDK = 24.1-1.6 +2.5 and gBsBK = 33.3 -3.7 +4.0. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.

Environmental Performance Reviews. Peru 2016: Highlights and recommendations

The aim of this environmental performance review is precisely to help Peru assess its progress towards achieving its environmental goals, enrich and ensure that the necessary policy dialogue continues uninterrupted, promote better accountability and deepen the awareness of all actors involved in the economic and social development of Peru. The 66 recommendations included in this study target some of the country’s main environmental challenges.

Revisão taxonômica do gênero neotropical X.eropigo Pickard-Cambridge (Araneae, Corinnidae, Corinninae)

O gênero Xeropigo O. Pickard-Cambridge é revisado, com a proposição de sete espécies novas neotropicais.: X. candango, com base em machos e fêmeas de Brasília, Distrito Federal e Goiás, Brasil; X. rheánsae, com base em machos de Goiás, Brasil; X. camilae, com base em machos e fêmeas do norte e centro-oeste do Brasil; X. cotijuba, com base em machos e fêmeas do norte e centro-oeste do Brasil; X. pachitea, machos e fêmeas de Huánuco e Cajamarca, Peru; X. perene, com base em fêmeas de Junin e Loreto, Peru; X. brescoviti com base em machos de Beni, Bolívia.

A family history of serious complications due to BCG vaccination is a tool for the early diagnosis of severe primary immunodeficiency

Severe Combined Immunodeficiency (SCID) is one of the most severe forms of primary immunodeficiency (PID). Complications of BCG vaccination, especially disseminated infection and its most severe forms, are known to occur in immunodeficient patients, particularly in SCID. A carefully taken family history before BCG injection as well as delaying vaccination if PID is suspected could be a simple and effective method to avoid inappropriate vaccination of an immunodeficient child in some cases until the prospect of newborn screening for SCID has been fully developed. We describe a patient with a very early diagnosis of SCID, which was suspected on the basis of the previous death of two siblings younger than one year due to severe complications secondary to the BCG vaccine. We suggest that a family history of severe or fatal reactions to BCG should be included as a warning sign for an early diagnosis of SCID.

Reassessment of the taxonomic status of Amblyomma cajennense (Fabricius, 1787) with the description of three new species, Amblyomma tonelliae n. sp., Amblyomma interandinum n. sp. and Amblyomma patinoi n. sp., and reinstatement of Amblyomma mixtum Koch, 1844, and Amblyomma sculptum Berlese, 1888 (Ixodida: Ixodidae)

A reassessment of the taxonomic status of Amblyomma cajennense based on the morphological analyses of ticks from the whole distribution area of the species resulted in the redescription of A. cajennense, the validation of 2 species which had been reduced to synonymy in the past, Amblyomma mixtum and Amblyomma sculptum, and the description and definition of 3 new species, Amblyomma tonelliae n. sp., Amblyomma interandinum n. sp., and Amblyomma patinoi n. sp. This study provides descriptions and redescriptions, scanning electron microscopic and stereomicroscopic images, updated synonymies, information on geographical distributions, and host associations for each of the 6 species. Amblyomma cajennense s.s. is found in the Amazonian region of South America, A. interandinum is reported from the northern part of the Inter-Andean valley of Peru, A. mixtum is present from Texas (U.S.A.) to western Ecuador, A. patinoi occurs in the Eastern Cordillera of Colombia, A. tonelliae is associated with the dry areas of the Chaco region which spans from central-northern Argentina to Bolivia and Paraguay, whereas A. sculptum is distributed from the humid areas of northern Argentina, to the contiguous regions of Bolivia and Paraguay and the coastal and central-western states of Brazil.
