Optimal design of periodic functionally graded composites with prescribed properties
(SPRINGER, 2009)
The computational design of a composite where the properties of its constituents change gradually within a unit cell can be successfully achieved by means of a material design method that combines topology optimization ...
Uma introdução sobre os efeitos do Coeficiente de Poisson Negativo e conceitos de desenvolvimento para estruturas têxteis auxéticas
(Universidade Tecnológica Federal do ParanáLondrinaBrasilEngenharia de MateriaisUTFPR, 2022-06-18)
The auxetic behavior, notably the lateral expansion of a material or structure under longitudinal tension, promotes unique properties that result from the Negative Poisson Ratio (NPR), such as greater fracture toughness, ...
Auxetic properties of a newly proposed γ-graphyne-like material
(2022-01-01)
A new auxetic (negative Poisson's ratio values) structure based on a γ-graphyne structure, here named AγG structure, is proposed. The AγG structural/mechanical and electronic properties, as well as its thermal stability, ...

Aim To evaluate the association between outpatient's perceived psychosocial impact of dental aesthetics and experiencing discrimination at a Peruvian public hospital. Material and methods Cross-sectional study in a Peruvian ...
Factors associated with falls in older adults in chile. Analysis of the National Health Survey 2009-2010
(SOC MEDICA SANTIAGO, 2019)
Background: A decrease in functional capacity due to ageing is one of the main risk factors for falls in older people. Aim: To investigate factors associated with falls in Chilean older adults. Material and Methods: We ...
