Abstract. The main objective of the present work was to determine influence laser beam processing (LBP) on microstructure, microhardness, roughness, and corrosion resistance coatings produced C45 carbon steel by electro-spark deposition (ESD) process. studies were conducted using WC-Co electrodes Pulse Plasma Sintering method (PPS) nanostructural powders. deposited means EIL-8A they treated wit...

this paper presents the application of multivariate time series model (ardl) to investigate factors affecting bread waste and to explore the relationships among shortrun, longrun and error correction coefficient and the independent variables over the period 1978-2006. results reveal that gross national product and urbanization have positive effects on bread waste in the long term, while the bre...

PURPOSE Standardized patient (SP) methodology is the gold standard for evaluating clinical practice. This approach was used to investigate the content of typical optometric eyecare in England and the reproducibility of refractive error measurement using prescriptions obtained by three SPs. METHODS The three SPs were independently examined by three to four expert optometric clinicians to obtai...
