Underplatform dampers (UPDs) are still in use to reduce the vibration amplitude of turbine blades and to shift the position of resonant frequencies.The dynamics of blades with Postcards UPDs is nonlinear and the analysis is challenging from both the experimental and the numerical point of view.A key point in obtaining a predictive numerical tool is
Abstract Continuous approaching and detaching displacement usually occurs in an adhesion test.Here, we found a transient adhesion force at the end of a non-fully detached contact.This force occurred when the nominal detaching displacement was less than the traditional quasi-static theory predicted zero force point.The BEACH STYLE CREAM transient ad
ABSTRACT: The presence of Salmonella serotypes is a major safety concern of the food industry and poultry farmers.This study aimed to isolate and identify Salmonella spp.from a chicken processing facility by PCR and pulsed-field gel electrophoresis (PFGE).In addition, the biofilm-forming abilities of the isolated bacteria on stainless steel, silico
