To solve the problem of blockage of crystallization in tunnel drainage pipes in hard water area, electric field devices are designed and applied in the transversal tunnel drainage pipe according to the fundamental law of crystallization.Laboratory Display Pieces tests were carried out to test the crystallizing tunnel drainage pipe under the effect
Abstract Objectives This study evaluated the impact of self-management interventions based on the COM-B model on peri-implant conditions in older adults with periodontitis.Materials and methods The patients were randomly divided into two groups: Group 1 (control group) received only an oral Crutches - Underarm Support Crutches health education (OHE
Immunogens and vaccination regimens can influence patterns of immune-epitope recognition, steering them towards or away from epitopes of potential viral vulnerability.HIV-1 envelope (Env)-specific antibodies targeting variable region 2 (V2) or 3 (V3) correlated with protection during the RV144 trial, however, it was suggested that the immunodominan
Abstract The use of pulse voltage can greatly improve the precision of electrochemical EnlargementGear microfabrication, and the narrower the pulse width of the applied pulse voltage signal, the higher the machining precision.However, the commonly used chopper circuit topology of pulse power supplies is limited by the maximum switching frequency of
