Variational Inequalities and complementarity problems in contact mechanics : theory and application

Rula Ismael Hamad Abstract : This paper explores the role of variational inequalities and complementarity problems in solving complex contact mechanics phenomena, including non-penetration constraints, friction, and multibody interactions. Traditional methods in contact mechanics often fall short in modeling nonlinearities and discontinuities encountered in practical engineering scenarios such as tire-road interactions, gear contacts, and biomechanical

Impact of some mechanical properties of Room Temperature Maxillofacial Silicone after addition of pomegranate peel powder

Aseel F. Kumail  Thekra I. Hamad Mohammed abdula ejresh Abstract : Background: Maxillofacial prosthetic materials must possess optimal physical, esthetic, and biological properties that remain stable over time to ensure patient acceptance and long-term clinical success. Silicone elastomers are the most commonly used materials due to their favourable characteristics; however, their performance remains limited by

Study of Quinolone Resistance Mechanisms in Clinical Pseudomonas aeruginosa Isolates

Hala Hammadi Mohammed Ejresh Alya Amer Rahi     Abstract : Pseudomonas aeruginosa is an opportunistic bacterium known for its capacity to resist multiple antibiotics, particularly quinolones, through both inherent and acquired mechanisms. Quinolone resistance primarily arises from mutations in chromosomal genes like gyrA and parC, as well as through the presence of plasmid-encoded qnr genes.
