Effect of cement fill ratio in loosening of hip implants. [PDF]
Biomatter, 2012 Femoral loosening is one of the most prevalent causes of revision orthopedic surgeries. Cement mantle thickness has been directly correlated with femoral loosening. If the mantle is too thick, there is an increased risk of radiolucent lines and inconsistent densities.

Factors influencing power consumption and power-saving measures in ESR process [PDF]
China Foundry, 2019 Since the USA patent of electroslag remelting (ESR) metallurgy was held by P. K. Hopkins in 1940, the ESR technology has now entered a relatively mature stage after a 70-year history of development.

Does the Surgical Approach Influence the Canal Fill of the Proximal Femur for Hip Arthroplasty?
Arthroplasty Today, 2021 Background: Choosing the right size of the stem is crucial for uncemented hip arthroplasty. Undersizing can lead to early loosening, peri-prosthetic fracture due to femoral implant insertion, and/or osteointegration failure.

A modified squeeze equation for predicting the filling ratio of nanoimprint lithography [PDF]
Nano Convergence, 2017 A numerical method using the modified squeeze model is proposed in this paper in order to overcome the limitation of the established squeeze equation and obtain filling ratios for nanoimprint lithography (NIL). Because the imprinting velocity is overestimated when the ratio of indenter width to polymer thickness is close to unity, the modified equation

BioResources, 2022 Process conditions were investigated relative to the use of the fly ash pre-desilication-alkali lime sintering method to extract calcium silicate, which is a by-product of alumina co-production technology, for use as paper filler. The ratio of different fiber raw materials, filler filling ratio, and filling method were studied, and papermaking ...
