Background: Injecting drug users (IDUs) and prisoners are considered to be highly vulnerable to human immunodeficiency virus (HIV) infection in Iran.This study was carried out to determine the prevalence of HIV infection among IDUs released from jail in Bahar (Hamadan, Iran).Methods: In a cross-sectional Hair Extensions study, 118 IDUs who were pri
Introduction Approximately 10 300 people are diagnosed with pancreatic cancer each year in the UK.The cancer and its treatment inflict a significant physical, functional and emotional burden on patients.Research suggests that patients have many ongoing needs for support and care, but that these needs are not met by existing services.Family members
One commonly used lubricant in rolling bearings is grease, which consists of base oil, thickener and small amounts of additives.Commercial greases are mostly produced Skincare from petrochemical base oil and thickener.Recently, the development of base oils from renewable resources have been significantly focused on in the lubricant industry.However
Abstract The tribological properties of self-lubricating composites are influenced by many variables and complex mechanisms.Data-driven methods, including machine learning (ML) algorithms, can yield a better comprehensive understanding of complex problems under the influence of multiple parameters, typically for how tribological performances and ma
In this paper, we propose an original complex network model for an epidemic problem in an heterogeneous geographical area.The complex network is constructed by coupling nonidentical instances of a HIV/AIDS epidemiological model for which a disease-free equilibrium and an endemic equilibrium can coexist.After proving the existence of a positively in
