Friction stir lap welding (FSLW) of 6061-T6 aluminium sheet and DX51D galvanized steel sheet was carried out by adding zinc foil to the lap interface and studying the influence of the zinc foil on the formation mechanisms and mechanical properties.The influence of the thickness of zinc foil, the plunge depth of the shoulder and the shape Tread Belt
Billions of packages are automatically handled in warehouses every year.The gripping systems are, Shampoos however, most often oversized in order to cover a large range of different carton types, package masses, and robot motions.In addition, a targeted optimization of the process parameters with the aim of reducing the oversizing requires prior kn
Abstract Biofilms are organised heterogeneous assemblages of microbial cells that are encased within a self-produced matrix.Current estimates suggest that up to 80% of bacterial and archaeal cells reside in biofilms.Since biofilms are the main mode of microbial life, understanding their biology Treats Bulk and functions is critical, especially as c
Vaccination concerns and motivations regarding this topic are increasingly discussed not only JOINT-PRO FORMULA among specialists but also by the general public.In this paper I rely on the Eurobarometer 91.2/ 2019 survey and I classify European respondents in four attitudinal profiles, from the skeptical ones to the pro-vaccination type.This survey
An important part of scientific and technical support of civil engineering facilities at a construction stage - evaluation of influence of fluctuations from a designed geometry onto mechanical safety parameters of load-bearing metal structures - is considered.A multi-tier structure (industrial frame tower) is employed Cookie Jar to demonstrate main
