Clinical outcomes of a novel flowable calcium silicate cement in equine endodontic treatment

Equine Veterinary Journal, EarlyView.
Abstract Background Orthograde endodontic treatment of equine cheek teeth is performed infrequently with variable success rates of obturation with calcium hydroxide paste (CHP). A novel flowable calcium silicate cement (eCSC) formulated for use as an obturation material in equine teeth has demonstrated acceptable canal filling volumes and evidence of ...

Effect of montmorillonite as additive on the properties of cement-based composites

Science and Engineering of Composite Materials, 2012
The aim of this study was to investigate the effect of montmorillonite as additive on the properties of cement paste and mortar. Montmorillonite was used at 0%, 5%, 10% and 15% additive by weight of cement, and the water/cement ratios of 0.45 and 0.55 ...

Effect of Different Particulate Materials and Graphene Oxide on Properties of Cement Paste

Taiyuan Ligong Daxue xuebao
Purposes For improving the mechanical properties of GO incorporated cement paste, two types of nano-silica (crystalline and amorphous) and coal-bearing metakaolin (CMK) were used seprately to improve GO dispersion in cement paste.

Living on the edge: Habitat characteristics of northern myotis at the periphery of its distribution

The Journal of Wildlife Management, EarlyView.
Northern myotis selected tall trees with minimal decay, in patches with other roosting options. In our study area, these trees occurred in narrow bands within an agricultural matrix, differing from contiguous forest at the core of the species' distribution. Nevertheless, bats selected the tallest trees in the densest patches available.

Stress development at the cement paste-steel interface for thin cement paste coatings

Cement and Concrete Research, 1989
Abstract A novel technique for determining the development of stress at the steel-cement interface for thin cement paste coatings is briefly described. A series of interfacial stress-hydration time curves are presented for three matrix systems: cement + silica fume, cement + calcium carbonate, and tricalcium aluminate + gypsum.

Hearing Preservation Rates After Cochlear Implantation Using Soft Surgery Techniques

The Laryngoscope, EarlyView.
ABSTRACT Objectives To determine if hearing preservation rates after cochlear implantation varied over time with soft surgery techniques. Methods The hearing preservation rate over time in adult cochlear implant patients over 10 years was analyzed. The association between hearing preservation rate and sex, age, perioperative steroid dose, and type of ...

Characterization of Dental Composite Resin with Additional TiO2 Nanoparticle Filler

Macromolecular Symposia, EarlyView.
Silanized SiO2‐based dental composite resins with and without TiO2 nanoparticle addition were fabricated using a Bis‐GMA/TEGDMA resin matrix and photopolymerized under 468‐470 nm UV light. The resulting composites, composite I (55% SiO2) and composite II (50% SiO2 + 5% TiO2), were characterized via scanning electron microscopy (SEM), Fourier transform ...
