1. SPATIAL AUTOCORRELATION OF PHYSICAL ATTRIBUTES OF AN OXISOL
ABSTRACT Studies that seek to identify a smaller number of soil attributes that represent others can generate less expenditure of time and financial resources for monitoring cultivated areas. Thus, this study aimed to analyze the spatial distribution and spatial autocorrelation of physical attributes of an Oxisol (Latossolo Vermelho Amarelo, Brazilian Soil C

2. Outcome of staged excision with pathologic margin control in high-risk basal cell carcinoma of the head region,
Abstract Background: High-risk basal cell carcinoma involves a significant rate of basal cell carcinoma that requires Mohs micrographic surgery for definitive treatment. Staged excision with pathologic margin control is a simple, accessible, and curative procedure suggested for the treatment of high-risk basal cell carcinoma. Objective: To evaluate the res

3. Epidemiological survey of hepatitis C in a region considered to have high prevalence: the state of Minas Gerais, Brazil
Abstract INTRODUCTION: The prevalence of hepatitis C virus (HCV) infection is affected by demographic, virological, clinical, and lifestyle-related factors and varies in different regions in Brazil or worldwide. The present study aimed to clarify the epidemiological patterns of HCV infection in the interior region of Brazil. METHODS: This study was condu

4. Motor coordination as predictor of physical fitness in prepubertal boys
Resumo A competência motora está associada a inúmeras variáveis relacionadas à saúde da população pediátrica. O presente estudo teve como objetivo analisar o efeito do nível de coordenação motora no desempenho em diversos testes de aptidão física de meninos pré-púberes, antes e depois de controlar o efeito exercido pela massa corporal. A amos

5. Electrodeposition of Prussian Blue/Carbon Nanotube Composites at a Liquid-Liquid Interface
The iron complex hexacyanoferrate (Fe4[Fe(CN)6]3), known as Prussian Blue (PB), was electrodeposited over a free-standing carbon nanotube (CNT) film assembled at the interface between two immiscible liquids, water and 1,2-dichlorobenzene. Polarization of the interface achieved through a fixed potential or under potential variation enabled iron present inside

6. Modelling of Rocking and Sliding Effects in the Seismic Analysis of a Free-Standing Column
Abstract A study on the seismic response of a free-standing marble column, including rocking and sliding effects, is presented in this paper. The rocking-sliding model implemented for the development of the analyses corresponds to the basic theoretical and numerical simulation of the dynamic phenomenon. The assessment procedure adopted for the application of

7. Grazing of particle-associated bacteria-an elimination of the non-viable fraction
Abstract Quantification of bacteria being grazed by microzooplankton is gaining importance since they serve as energy subsidies for higher trophic levels which consequently influence fish production. Hence, grazing pressure on viable and non-viable fraction of free and particle-associated bacteria in a tropical estuary controlled mainly by protist grazers wa

8. Melting Behaviour of Bi1-xSbx Free Standing Alloy Nanoparticles Synthesized via Solvothermal Route
The present investigation aims at understanding the effect of size on melting behaviour of free standing alloy nanoparticles. Alloy nanoparticles of Bi1-xSbx (x=0.12, 0.25, 0.50 and 0.75) have been synthesized by solvothermal route using sodium borohydride (NaBH4) as a reducing agent. The samples were characterized by X-ray diffraction (XRD) and transmission

9. Daily activity patterns of Saanen goats in the semi-arid northeast of Brazil
The objective of the study was to characterize the daily feeding activity patterns of Saanen goats (Capra hircus) as a function of changes in climatic variables. The investigation was conducted in the municipality of Cruzeta, 300 km from the city of Natal, Brazil. Seventeen free-ranging female Saanen goats were selected for observation, wherein they were kep

10. Microstructural control of Co-based PTA coatings
Cobalt-based alloys are widely used as hardfacing materials when wear resistance is required at room temperature or high temperature applications. However, their performance is a consequence of their microstructures that depends on the processing conditions. This work focused on the influence of solidification rate on the structure development by processing

11. Crescimento de nanofios auto-sustentados de arseneto de índio por epitaxia por feixes moleculares
This Thesis reports the experimental and theoretical works related to the growth and characterization of free-standing gallium indium arsenide nanowires grown by Molecular Beam Epitaxy (MBE). The growth mechanisms of free-standing nanowires remain barely known and explored in its fundamental aspects. The theoretical models of the formation of free-standing n

12. Geometria, Topologia e Elasticidade: aplicações a membranas e outros sistemas bidimensionais
Geometry, topology and elasticity are found in various branchs of physics and they play important roles in the understanding of many physical phenomena. In this work, we present three diferent systems where we can see such importance. First, a quantum neutral particle, constrained to move on a conical surface, is used as a toy model to explore bound states d
