Utilizing coral aggregate concrete (CAC) for construction on remote islands can significantly reduce cost and period, CO 2 emission, consumption of non-renewable energy. The durability reinforced CAC structures is critically influenced by their resistance to chloride attack. In this study, a reactive transport modelling was developed investigate ingress in CAC, which COMSOL-PHREEQC interface ba...

BACKGROUND Coronary artery calcification which is determined quantitatively by coronary calcium scoring has been known as a sign of coronary stenosis and thus future cardiac events; hence it has been noticed on spotlight of researchers in recent years. Developing different method for early and optimal detection of coronary artery disease (CAD) is really essential as CAD are the first cause of d...

Use of the scanning electron microscope (SEM) with X-ray microanalysis allows study of clinker and cements; permitting measuring bulk phase abundance and surface areas of the phases, as well as bulk chemistry of constituent phases can be carried out. Direct imaging of hydraulic cements by SEM yields a more complete picture of both bulk and surface phase compositions. Mass percentages obtained b...

Introduction. ALBO-HA (Vinca, Serbia) is new nanostructured calcium aluminate cement, synthesized as a potential alternative to mineral trioxide aggregate (MTA). The purpose of this study was compare the periapical tissue response cement with white MTA (MTA Angelus, Londrina, Brasil) root-filling material into root canal sheep?s teeth. Material and methods. Sixteen mandibular incisors from two ...

BACKGROUND The South Bay Heart Watch is a prospective cohort study designed to appraise the value of coronary calcium and risk factors for predicting outcomes in asymptomatic adults. Two factors that may be related to subsequent cardiovascular events are coronary calcium (CAC, a manifestation of subclinical atherosclerosis) and high-sensitivity C-reactive protein (CRP, a measure of chronic infl...

Alkali-free, aluminium-based accelerators are often used for shotcrete linings in tunnels and mines, where external sulfate attack can occur. Therefore, it is essential to know, if the influence of on cement hydrate assemblage negatively impacts resistance. This study focuses effect hydration consequences attack. Aluminum sulfate-based cause rapid setting due very early formation ettringite acc...

The aim of this study is to determine the effects of 1,25(OH)2D3 and its analogues on tumor growth and body weight, changes in plasma ionized calcium, parathyroid hormone-related protein (PTHrP) production, bone resorption, and the distribution of the 1,25(OH)2D3 receptor (VDR) on tumors in nude mice-bearing the canine adenocarcinoma (CAC-8). Thirty-seven nude mice were implanted subcutaneously...

BACKGROUND Hyperphosphatemia is one of the common complications in patients undergoing hemodialysis. Although calcium carbonate (CaC) is often used to control serum inorganic phosphorus level in dialysis patients, co-administration of gastric acid reducers (ARs) may interfere with the phosphate binding effect of CaC. We performed a retrospective medical chart review to study whether ARs attenua...
