Six potentially important wood adhesives for gluing southern pine and white oak flakeboards were evaluated for their perfonnances in steam-injection pressing and conventional platen pressing. Of the six resins tested, polyisocyanate resin perfonned well in both steam injection and conventional platen pressings. Phenol-fonnaldehyde (PF) and melamine urea-fonnaldehyde (MUF) resins perfonned poorl...
BACKGROUND Glioblastoma multiforme (GBM) is one of the most aggressive human tumors, and the establishment of an effective therapeutic reagent is a pressing priority. Recently, it has been shown that the tumor tissue consists of heterogeneous components and that a highly aggressive population should be the therapeutic target. METHODS Through a single subcutaneous passage of GBM cell lines LN4...
Abstract In the publication, results of an experimental analysis joint formation by pressing DX51D steel sheets with thickness 1.5 (mm) use a rigid punch and additional deformable rivet various shapes were presented. The influence diameter d = 5 (mm), similar to dimensions forming in case classic clinching variety on interlock parameters was investigated. used die four movable segments—dedicate...
One of the methods for making prototypes is incremental forming process. In this method, the forming tool, performs a pre-programmed movement by the CNC machine and runs the desired path. This modernization process is used in the automotive, aerospace, military, medical and other industries. One of the most influential parameters in this process is forming tool. This parameter is effective in f...
