The importance of wood relaxation when studying nail withdrawal capacity
Case Studies in Construction MaterialsNails are among the most widely utilised fasteners in timber construction. Nail withdrawal capacity (NWC) has been extensively studied; however, the specific mechanisms by which moisture affects NWC remain unclear.

Withdrawal capacity of screws in plywood and manufacturer dependencies
Engineering StructuresWithin civil engineering and design of load-bearing timber structures, the use of self-tapping screws for connections is common practice. In certain situations, the axial withdrawal capacity of screws in a wooden panel may be required, for instance when utilizing the rope-effect contribution to the lateral resistance.

Wood screw design: influence of thread parameters on the withdrawal capacity [PDF]
European Journal of Wood and Wood Products, 2021 AbstractSelf-tapping wood screws are important fasteners in timber construction. A characteristic of these screws is their high axial load-bearing capacity, which also depends on their withdrawal capacity. This is used for structural design and is thus an important optimization parameter for wood screws.

Drug‐metabolizing capacity in states of drug dependence and withdrawal [PDF]
British Journal of Pharmacology, 1972 Summary Drug‐metabolizing capacity was assessed in 8 barbiturate‐dependent and in 3 Mandrax‐dependent patients using, as indices, plasma antipyrine half‐life and in some cases urinary output of 6β‐hydroxycortisol. For comparison, antipyrine half‐life was also measured in volunteers before and after a period of taking hypnotic doses of these agents ...
