Dependence of contact area on the resolution of fractal interfaces in elastic and inelastic problems
(2011)Purpose - The purpose of this paper is to investigate the influence of the resolution with which interfaces of fractal geometry are represented, on the contact area and consequently on the contact interfacial stresses. The ... -
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 ... -
Efficacy of spinetoram as a contact insecticide on different surfaces against stored-product beetle species
(2014)Contact toxicity of spinetoram was evaluated in laboratory bioassays on concrete, ceramic tile, galvanized steel, and plywood. The efficacy of spinetoram was assessed at dose rates of 0.025 mg (AI)/cm(2), 0.05 mg (AI)/cm(2), ... -
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 ... -
Gradient Elastodamage Model for Quasi-Brittle Materials with an Evolving Internal Length
(2015)The article presents a new approach based on a strain gradient damage constitutive law for modeling quasi-brittle materials such as concrete. The authors use a weak type nonlocal formulation of the problem, relying on ... -
Knockdown and Mortality of Five Stored Product Beetle Species After Short Exposures of Thiamethoxam
(2014)Laboratory bioassays were conducted to evaluate the effectiveness of thiamethoxam, against five major stored-grain beetle species, the lesser grain borer, Rhyzopertha dominica (F.), the rice weevil, Sitophilus oryzae (L.), ... -
Residual Efficacy of Chlorfenapyr for Control of Stored-Product Psocids (Psocoptera)
(2014)The residual effect of chlorfenapyr (Phantom) was evaluated for residual control of three stored-product psocid species: Liposcelis bostrychophila Badonnel, Liposcelis entomophila (Enderlein), and Liposcelis paeta Pearman ... -
Size effects on strength, toughness and fatigue crack growth of gradient elastic solids
(2008)The present study investigates the microstructural size effect on the strength of a bar under axial loading, and on the toughness and crack growth of a beam under three-point bending within the framework of strain gradient ...
