We determined the activation volumes (V*) for polycrystalline magnesite with grain sizes of 2 and 80 µm deforming by low temperature plasticity (LTP) mechanisms (kinking and dislocation glide), diffusion creep, and dislocation creep at temperatures of 500, 750, and 900 °C, respectively, and a strain rate of 1−2 × 10−5 s&#
A large number of microorganisms colonize the intestines of animals.The gut microbiota plays an important role in nutrient metabolism and affects a number of physiological mechanisms in the host.Studies have shown that seasonal changes occur in the intestinal microbes of mammals that hibernate seasonally.However, these studies only focused on groun
Due to an increase in the number of internet users, electronic commerce has grown significantly during the last decade.Electronic auction (e-auction) is one of the famous e-commerce applications.Even so, security and robustness of e-auction schemes still remain a challenge.Requirements like anonymity and privacy of the b i d value are under threat
Animal activity in pigs can be a direct indicator of animal welfare.Passive infrared detectors (PID) provide one method of measuring animal activity on the pen level as a cost-effective and easy-to-use sensor technique.The study aimed to test PIDs on different commercial farms with fattening pigs.On each farm, a focus pen was selected and group act
During ultrafast laser-induced crystallization from glass with a non-congruent composition, a phase separation occurs.The morphology of the crystallized area, inside the heat-affected zone (HAZ), is spectacular showing a bouquet-like structure, under some specific conditions related to glass chemical composition and laser parameters.In this work, w
