Three New Species of Clonostachys (Hypocreales, Ascomycota) from China
Three new species of Clonostachys are introduced based on specimens collected from China. Clonostachys chongqingensis sp. nov. is distinguished by pale yellow to pale orange-yellow perithecia with a very low papilla, clavate to subcylindrical asci ...

Local buckling of steel cold-formed profiles under transverse bending [PDF]
Danger local buckling (LPA) are virtually ignored in most engineering methods for calculating the cross-section profiles with complex shapes. The problem of LPA rod is reduced to the problem of overall sustainability.

Influence of material removal on the dynamic behavior of thin-walled structures in peripheral milling [PDF]
Machining is a material removal process that alters the dynamic properties during machining operations. The peripheral milling of a thin-walled structure generates vibration of the workpiece and this influences the quality of the machined surface.
