Abstract The paper studies the initial boundary value problem related to dynamic evolution of an elastic beam interacting with a substrate through elastic-breakable forcing term. This discontinuous interaction is aimed model phenomenon attachment-detachment occurring in adhesion phenomena. We prove existence solutions energy space and exhibit various counterexamples uniqueness. Furthermore we c...

  Objective: Adhesion of Lactobacillus acidophilus (L. acidophilus) to dental porcelain surface may lead to gingival inflammation and secondary caries. Surface roughness is among the factors affecting this adhesion. The purpose of this study was to evaluate the effects of four different surface treatment methods on adhesion of L. acidophilus to dental porcelain.   Methods: Sixty specimens (3x10...

Clogging occurs during mechanical tunneling with a Tunnel Boring Machine (TBM) because of adhesion of clayey soils to the cutterhead and conveyor system. The present study examined the effects of water and sand contents on clogging in Montmorillonite clayeysoil. Testing was carried out using an adhesion test device on 28 samples with different water and sand contents to determine adhesionstress...

the objective of this study was to determine the effectiveness of topical administration of honey in prevention of or reduction in post-surgical peritoneal adhesions in dog. the study was conducted on 18 adultfemale mixed-breed dogs with a mean ± sd weight of 20 ± 4.25 kg. a standardized surgical trauma (serosaltrauma model) was made in the dogs’ descending colon to induce adhesion formation. t...

background: the aim of this study is to investigate the effect of vitamin a and c, as the agents that improve wound healing, on the adhesion formation process. materials and methods: sixty male wistar rats were used. they underwent midline laparotomy, for repair of a peritoneal injury, and were then assigned to four groups. group 1 (vitamin a) received 2000 units/kg intramuscular injection of v...

Polypropylene (PP) has poor adhesion to metals and other surfaces for its chemical structure. Hence, chemical modification of PP is necessary for metal surface coating application. In this research, grafting of maleic anhydride (MA) onto co(propylene-b-ethylene) in the presence of a dicumyl peroxide (DCP) was accomplished in a single screw extruder. Characteristics of the modified polymer were ...

introduction: opium addiction can change immune response to types of stress such as injury or trauma due to alterations in the in secretion status of cytokines in the body. in this study, effects of opium addiction on wound healing and post-operative adhesion bands were assessed after laparotomy. materials and methods: male rats (n=20) were randomly divided into opium addicted (documented with ...
