1. Modeling non-ideal velocity of detonation in rock blasting
Abstract The performance of commercial explosives is an important subject in rock blast ing modeling and simulation. As a result of its non-ideal behavior, these explosives usu ally react below their ideal detonation velocity. In these cases, the multi-dimensional effects, heterogeneities and confinement conditions become important for properly quantifying t

3. MECANISMO DE EVOLUÇÃO DE HIDROGÊNIO DURANTE A CORROSÃO DA LIGA 2198-T8 EM MEIO CONTENDO CLORETO: UMA ABORDAGEM ELETROQUÍMICA
Corrosion is still one of the most serious and frequent problems in industries. The phenomena involved in the corrosion mechanism of Al-alloys may be explained by formation of galvanic cells between the metal matrix and heterogeneities, such as precipitates, intermetallic phases leading to potential differences and electrochemical reactions. In the cathodic

4. Does Concern about Local Crime affect People’s Trust in the Police?
Resumo A confiança nas instituições é um dos pilares centrais da estabilidade das democracias. Ao explorar um banco de dados exclusivo relacionado à confiança nas instituições brasileiras, este estudo investiga o efeito da preocupação sobre o crime local na confiança na polícia. Exploramos dados da Pesquisa Confiança na Justiça, realizada para

5. La antropología latinoamericana ante la violencia de la incomprensión
Resumo Quando crescem novos autoritarismos com claras características fascistas, a antropologia assume novos desafios: repor as heterogeneidades constitutivas, suas histórias peculiares, seus pontos de vista e suas tramas relacionais. Não se trata apenas de alteridades radicais. São também as alteridades vividas e impensadas da vida cotidiana, onde terr

6. Phase Separation and Development of the Microstructure for Stainless Steel to Copper Alloy Weld Joints Using a Fiber Laser
ABSTRACT Stainless steel and copper alloys joints are often applied in aerospace, marine and power industries where both high thermal and electrical conductivity (Cu) and corrosion resistance (steel) are required. In the aerospace industry, in particular for the combustion chamber of rocket engines, copper and steel combinations offer perfect materials selec

8. Inequities in access to mammographic screening in Brazil
Resumo: O estudo teve como objetivos descrever a distribuição espacial do rastreamento por mamografia entre áreas geográficas pequenas (microrregiões) no Brasil, além de investigar se as diferenças observadas estavam associadas a inequidades espaciais nas condições socioeconômicas, na prestação de assistência à saúde e no uso de serviços de s

9. Efficacy of stem cells on bone consolidation of distraction osteogenesis in animal models: a systematic review
Abstract Distraction osteogenesis (DO) relies on the recruitment and proliferation of mesenchymal stem cells (MSC) to the target site, where they differentiate into osteoblasts to promote bone formation. Nevertheless, MSC recruitment appears to be slow and limits bone formation in DO defects. Thus, this systematic review aims to evaluate the ability of local

10. Cretaceous carbonatites of the southeastern Brazilian Platform: a review
ABSTRACT: This paper reviews general aspects of alkaline-carbonatitic rocks of Brazilian, Paraguayan and Bolivian terrains. Although 30 such occurrences are known in literature, only the major ones have been thoroughly investigated. The carbonatites are of Cretaceous age, with two well-defined Lower Cretaceous and Upper Cretaceous generation episodes. A clea

11. Heterogeneous Microtubules of Self-assembled Silver and Gold Nanoparticles Using Alive Biotemplates
Microtubules were constructed by covering the fungus Aspergillus aculeatus sequentially with silver and gold nanoparticles, resulting in a stable hybrid mesostructured material that presented three distinct regions containing different combinations of silver and gold nanoparticles. These heterogeneities were determined by the hyphal growth since the impossib

12. Influence of casting heterogeneities on microstructure and mechanical properties of austempered ductile iron (ADI)
ABSTRACT An investigation was carried out to examine the influence of as-cast heterogeneities on the resulting microstructure and mechanical properties of an austempered ductile cast iron (ADI). A commercial hypereutectic ductile iron alloy with 3.59% C, 2.68% Si, 0.24% Mn and 0.46% Cu (in wt. %) was produced in a coreless induction furnace. The specimens we
