13. STUDY OF THERMAL EXPANSION AND COMPRESSION STRENGTH OF THREE WOOD SPECIES FROM PLANTATIONS
ABSTRACT The objective of this study was to evaluate the effect generated by a thermal treatment on the dimensional changes and compression behavior of three wood species from commercial plantations (Eucalyptus nitens, Tectona grandis and Gmelina arborea). To accomplish the goal, dilatometric and compression tests were performed in the three directions of wo

15. Efficacy and safety of dimeticones in the treatment of epidermal parasitic skin diseases with special emphasis on tungiasis: an evidence-based critical review
ABSTRACT Epidermal parasitic skin diseases encompass scabies, pediculosis, cutaneous larva migrans, myiasis, and tungiasis. Tungiasis is probably the most neglected of all Neglected Tropical Diseases (NTD). It occurs in South America, the Caribbean and Sub-Saharan Africa and affects marginalized populations where people live in extreme poverty. In endemic co

16. Composite floor system with CFS trussed beams, concrete slab and innovative shear connectors
Abstract Steel and concrete floor systems are widely applied for buildings and provide excellent structural response, optimized material consumption, reduced beam height, and improved bending strength and stiffness capacity. In recent years, many experimental investigations concerned with new alternatives addressed to efficient interaction between steel and

17. Effect of Welding Parameters on Nanostructured Fe-(C, B)-(Cr, Nb) Alloys
New nanostructured Fe-(Nb,Cr)-(C,B) multicomponent alloys have been developed for hardfacing application. They have better wear resistance than traditional Fe-Cr-C alloys. The nano-alpha-Fe, eutectic and hard carboborides phases of the weld metal usually show variations with the welding procedure. 6 test samples with different heat input were welded. It was

22. Assessment of an anti-ageing structured cosmetic formulation containing goji berry
Based on previous studies, it has been found that goji berry (GB), popularly known as a ‘miracle fruit’, has excellent antioxidant potential and can be used in the treatment of skin disorders associated with ageing. This study aimed to incorporate GB into a structured cosmetic in order to optimise its penetration. Stability studies of the formulation, de

23. Caracterização Mecânica da Região Soldada de Tailor Welded Blanks (TWB) a Partir do Perfil de Microdureza
Resumo No Tailor Welded Blank (TWB) são soldadas chapas de especificações distintas, antes da conformação. Sua caracterização, na região soldada, por métodos convencionais de tração, pode ser dificultada pelo estreito comprimento da solda. Novas metodologias e alternativas são analisadas. Este trabalho visou caracterizar mecanicamente a região s

24. Ultrasound elastography in patients with fatty liver disease
Resumo Esteatose hepática ocorre pelo acúmulo de lipídios nos hepatócitos, sua cronificação cursa com inflamação lobular e evolui com fibrose hepática, cirrose e carcinoma hepatocelular. O diagnóstico precoce do acometimento hepático é desejável em razão da melhor resposta terapêutica dos pacientes na fase inicial da doença. O exame físico n
