These results show the importance to control the nitriding parameters to avoid abrupt hardness changes along the case that can jeopardize the gear performance.
The crowns were subsequently loaded at the incisal edge with a flat, steel cylinder of 30 mm in diameter cushioned with a 2-mm-thick rubber disc of hardness 90 Shore A (EPDM 90) to avoid contact damage (Fig. 2).
It is generally accepted that the indentation depth should never exceed 30% of the film thickness to avoid the substrate effect on hardness and modulus measurements [18].
I wanted to avoid the mess, tame the hardness of the skin, and add some flavor.
Another issue is the hardness of the water; where it is necessary to use hard water, regular re-potting is recommended to avoid the build up of salts.
Use the mixer attachment to gently break mascarpone into small pieces to avoid them flying out of bowl Run mixer until required hardness achieved.
In general, the depth of indentation should not cross more than 10% of the film/wire thickness to avoid substrate effects in the hardness/modulus data.
In order to avoid high costs for disposal, the brines should be processed into useful forms such as fresh and low-hardness water.
To minimize the risk of layer wear due to an excessive difference in hardness and residual stress gradients, a multilayer approach to covering CoCrMo implants has been developed that causes only minor tensile stress within the layer, and it has been shown to avoid delamination in an in vitro set-up (Reich et al. 2010).
Simulated root canals in resin blocks are usually recognized as valid study models to avoid the variation among natural teeth [ 6], since simulated root canals could be manufactured by standardization of working length, taper, curvature, and "tissue" hardness in three dimensions [ 2].
To avoid hurting yourself, it might be a good idea to set up some kind of mat on the ground to lessen the hardness of your cartwheel surface, especially if you are a gymnastics beginner.
