Objective: To investigate the association of the failure of porcelain laminate veneers with factors related to the patient, material, and operator.Methods: This clinical survey involved 29 patients (19 women and 10 men) and their dentists, including undergraduate and postgraduate dental students and dental interns.Two questionnaires duospiritalis.c
Compound feeds are favorable environments for microorganisms, namely bacteria and fungi.Both groups contain nonpathogenic, opportunistic and pathogenic members.Bacteria can cause infections, and fungi can cause mycotoxicoses, so controlling microbial contamination of feed is of great importance.Sources of microbial contamination of compound feed in
A thermal insulation layer is often deposited on the lining structure of tunnels in cold regions to solve the problem of frost turbo air m3f72-3-n damage.When the air humidity in the tunnel becomes excessively high, the thermal insulation material tends to absorb water, leading to significant changes in thermal conductivity.Moreover, the temperatur
A super-resolution generation us polo assn mens sweaters model for cultural relics image(CR-SRGAN) was proposed in order to solve the problems caused by the long history, such as the dark and old surface of cultural relics and the fading of images.Aiming at the problem of image degradation, the model obtained the low resolution image data set corre
We consider flows on a closed surface with one or here more heteroclinic cycles that divide the surface into two regions.One of the region has gradient dynamics, like Morse fields.The other region has Hamiltonian dynamics generated by the field of the skew gradient of the simple Morse function.We color touch 7/97 construct the complete topological
