A numerical method is presented to investigate the dynamic response of Moisturizer uniform orthotropic beams subjected to an impact of a mass.Higher order shear deformation and rotary inertia are included in the analysis of the beams.The impactor and laminated composite beam are treated as a system.The nonlinear differential governing equations of

Gob-side entry retaining (GER) play a crucial role in enhancing coal recovery, improving roadway stress conditions, and ensuring safe and efficient mining operations.This study focuses on investigating the stability characteristics of surrounding rock using flexible formwork concrete (FFC) along the headgate of 3405 panel.According to the fracture

The global interest in solar energy as an alternative to traditional fuels has led to a Incense significant overall increase of attentiveness to solar energy systems, especially the solar chimney system.Because one potential drawback of solar chimney systems is the low efficiency of more traditional solar chimneys, researchers and scientists are tr

Despite extensive monitoring programs and preventative measures, Salmonella spp.continue to cause Sugar tens of thousands human infections per year, as well as many regional and international food-borne outbreaks, that are of great importance for public health and cause significant socio-economic costs.In Germany, salmonellosis is the second most c
