The use of supplementary cementing materials is gradually increasing due to technical, economical, and environmental benefits. Supplementary cementitious materials (SCM) are most commonly used in producing ready mixed concrete (RMC). A quantitative understanding of the efficiency of SCMs as a mineral admixture in concrete is essential for its effective utilisation. The performance and effective...

Lumbar interbody fusion is commonly performed by inserting an implant into the disc space. Interbody fusions are benefi cial because they result in high fusion rates, maintain spinal alignment, and allow for indirect decompression of the neuroforamen.1 Currently, the two most commonly used implants are made of polyether ether ketone (PEEK) or allograft bone. Threaded titanium (Ti) cages were us...

objective(s):anodized treated titanium surfaces, have been proposed as potential surfaces with better cell attachment capacities. we have investigated the adhesion and proliferation properties of h9c2 cardiac myoblasts on anodized treated titanium surface.  materials and methods: surface topography and anodized tubules were examined by high-resolution scanning electron microscopy (sem). control...

This paper is dedicated to optimization of socalled first order differential (PC) inclusions in gradient form on a square domain. As a supplementary problem, discreteapproximation problem is considered. In the Euler-Lagrange form, necessary and sufficient conditions are derived for partial differential inclusions (PC). The results obtained are based on a new concept of locally adjoint mappings.
