Conical indentation of incompressible rubber-like materials
(2009)In the last decade, the indentation test has become a useful tool for probing mechanical properties of small material volumes. In this context, little has been done for rubber-like materials (elastomers), although there ... -
Dependence of friction coefficient on the resolution and fractal dimension of metallic fracture surfaces
(2013)The paper studies the friction mechanism that is developed between metallic fracture interfaces of fractal geometry. The main purpose of the paper is to investigate how both the resolution and the fractal dimension of the ... -
Development of Strong Surfaces Using Functionally Graded Composites Inspired by Natural Teeth-Finite Element and Experimental Verification
(2010)Functionally graded materials (FGMs) are composite materials that exhibit a microstructure that varies locally in order to achieve a specific type of local material properties distribution. In recent years, FGMs appear to ... -
Efficacy of two formulations of pirimiphos-methyl as surface treatment against Sitophilus granarius, Rhyzopertha dominica, and Tribolium confusum
(2014)In the present work, the insecticidal effect of two pirimiphos-methyl formulations [emulsifiable concentrate (EC) and capsule suspension (CS)] as surface treatment on concrete, plywood, galvanized metal, plastic, and ceramic ... -
Elastic and viscoelastic indentation of flat surfaces by pyramid indentors
(2006)The present work presents the results of frictionless and adhesionless contact of flat surfaces by pyramid indentors. The materials of the contacting solids were modelled as homogeneous and isotropic, linear elastic, as ... -
Migration of substances from food packaging materials to foods
(2004)The employment of novel food packaging materials has increased the number of occurring hazards due to the migration from packaging material to the packaged food. Although polymers have mainly monopolized the interest of ... -
Self-concept, social position and social participation of pupils with SEN in mainstream primary schools
(2013)Drawing on a recent research project, this paper questions the literature's dominant representation of children with special educational needs (SEN) as holding negative perceptions of themselves and being socially isolated. ...
