1. Indicator kriging applied to RMR geomechanical modelling in a Pb-Zn deposit case study
Abstract The opening of a mining enterprise requires knowledge of the geomechanical characteristics of the mineral deposit, which will be worked according to the use of parameters of stability and/or resistance of the material, as well as the discontinuities present in the rock. In this study, the Rock Mass Rating methodology was used to propose a geomechani

2. La vida social de la energía: apuntes para el estudio territorializado de las transiciones energéticas
Abstract This paper presents a theoretical and methodological proposal for the sociological study of energy transition towards non-conventional renewable energy, as a process of induced transformation related to climate change, whose courses of action are not exempt from socio-technical controversies. The proposal is based on a four-year research program on

4. Development and psychometric evaluation of the Mandarin Chinese version of the Yale-Brown Obsessive-Compulsive Scale – Second Edition
Objective: To examine the psychometric properties of the Chinese version of the Yale-Brown Obsessive Compulsive Scale – Second Edition (Y-BOCS-II). Method: A total of 86 adults with a primary diagnosis of obsessive-compulsive disorder (OCD), ranging in age from 15 to 78 years, participated in the study. Participants were administered the Y-BOCS-II by a t

5. Translation and validation of the Brown attention-deficit disorder scale for use in Brazil: identifying cases of attention-deficit/hyperactivity disorder among samples of substance users and non-users. Cross-cultural validation study
ABSTRACT BACKGROUND: The Brown Attention-Deficit Disorder Scale (BADDS) was developed as a self-report assessment that was designed to screen for presence of symptoms of attention deficit hyperactivity disorder (ADHD). The objective here was to translate and validate the adult self-report BADDS for use in Brazil. DESIGN AND SETTING: Cross-cultural valida

6. Phenomenal Conservatism and the Demand for Metajustification
ABSTRACT This paper is on the justification of (PC), the epistemic principle defended by M. Huemer in his Phenomenal Conservatism theory. Put in a straightforward way, we can (and should) ask: what reasons are there for thinking that (PC) is true, that is, for thinking that appearances justify beliefs? This question corresponds - to use L. BonJour’s vocabu

7. Components of sustainable animal production and the use of silvopastoral systems
ABSTRACT There is an urgent need for sustainable animal production systems. A system or procedure is sustainable if it is acceptable now and if its expected future effects are acceptable, in particular in relation to resource availability, consequences of functioning, and morality of action. What might make any animal usage system unsustainable? The system m

8. Role of Cured Epoxy and Block Copolymer Addition in Mechanical and Thermal Properties of Polyethylene
This work aims to investigate the role of epoxy addition in high density polyethylene (HDPE) matrix. The block copolymer polyethylene-b-poly (ethylene glycol) (PEG-co-PE) was used as a compatibilizer. The samples were obtained by melt mixing using a torque rheometer. Instrumental nanoindentation was used to determine Young's modulus and nanohardness, thermal

10. The use of singleplex and nested PCR to detect Batrachochytrium dendrobatidis in free-living frogs
Many microorganisms are able to cause diseases in amphibians, and in the past few years one of the most reported has been Batrachochytrium dendrobatidis. This fungus was first reported in Brazil in 2005; following this, other reports were made in specimens deposited in museum collections, captive and free-living frogs. The aim of this study was to compare si

11. Heterojunction between Al2O3 and SnO2 thin films for application in transparent FET
Alternative materials for use in electronic devices have grown interest in the past recent years. In this paper, the heterojunction SnO2/Al2O3 is tested concerning its use as a transparent insulating layer for use in FETs. The alumina layer is obtained by thermal annealing of metallic Al layer, deposited by resistive evaporation technique. Combination of und

12. Cutaneous melanoma in the State of São Paulo: a spatial approach
BACKGROUND:Cutaneous melanoma is a skin cancer with low incidence but high mortality rates. Several factors are associated with increased risk of melanoma, such as excessive sun exposure, fair skin, and family history, among others. Little is known about the spatial distribution of this cancer in Brazil.OBJECTIVE:To identify, through the use of geostatistica
