Double-punching PMBL

Success stories in looking for effective strategies against cancer often have their roots in pathology. In case of primary mediastinal B-cell lymphoma (PMBL), this was likely the recognition as a distinct subtype of diffuse large B-cell lymphoma (DLBCL) in the early 80s [1, 2]. Initially a controversial entity, over the last 30 years, it has become clear that PMBL differs in pathogenesis, clini...

Meniscal shear stress for punching.

AIM Experimental determination of the shear stress for punching meniscal tissue. METHODS Meniscectomy (surgical treatment of a lesion of one of the menisci) is the most frequently performed arthroscopic procedure. The performance of a meniscectomy is not optimal with the currently available instruments. To design new instruments, the punching force of meniscal tissue is an important parameter...

Strength of Footing with Punching Shear Preventers

The punching shear failure often governs the strength of the footing-to-column connection. The punching shear failure is an undesirable failure mode, since it results in a brittle failure of the footing. In this study, a new method to increase the strength and ductility of the footing was proposed by inserting the punching shear preventers (PSPs) into the footing. The validation and effectivene...

Punching strength of actual two-way slabs

Many building codes rely on empirical formulations with respect to the punching shear design provisions. Such empirical equations are typically calibrated on the basis of laboratory tests performed on simplified geometries (usually isolated specimens) with usually statically-determined loading conditions. On the contrary, actual structures, particularly two-way slabs, are continuous and highly ...
