AIM This in vitro study compares a new system for manual chair side fabrication of indirect composite restorations, which uses silicone models after alginate impressions, to CAD/CAM-technology and laboratory manual production techniques. MATRIALS AND METHODS: and study design Each 10 composite inlays were fabricated using different types of production techniques: CAD/CAM- technology (A), the ne...

The knowledge of biodiesel density over large ranges of temperature and pressure is important for predicting the behavior of fuel injection and combustion systems in diesel engines, and for the optimization of such systems. In this study, cottonseed oil was transesterified into biodiesel and its density was measured at temperatures between 288 K and 358 K and pressures between 0.1 MPa and 30 MP...

Antioxidants are widely used in food products to preserve deterioration of their lipid components. Lately the nutraceutical properties of such compounds have driven much attention for their relationship with human health, and then natural antioxidants are preferred. Among natural antioxidants, rosemary (rosmarinus officinalis L.) has been described as one of the spices with higher antioxidant a...

This study evaluated the fracture strength of teeth restored with bonded ceramic inlays and overlays compared to sound teeth. Thirty sound human maxillary premolars were assigned to 3 groups: 1- sound/unprepared (control); 2- inlays and 3- overlays. The inlay cavity design was Class II MOD preparation with an occlusal width of 1/2 of the intercuspal distance. The overlay cavity design was simil...

INTRODUCTION The visual outcome of cataract surgery in patients with a previous history of KAMRA inlay implantation is an emerging issue for which limited research exists. The purpose of this study is to describe postoperative visual outcomes in this patient population. METHODS This is a case series with retrospective chart review. Seven patients underwent cataract surgery following KAMRA cor...

There are several types of designs used for unicompartmental tibial components. The all-plastic inlay component is recessed and it preserves bone around the outer edge of the tibia. For an onlay component, the entire condyle is resected, and the plastic bearing is usually metal-backed, although all-plastic components are also available. The purpose of this study was to investigate the hypothesi...

Citrus fruits have potential health-promoting properties and their essential oils have long been used in several applications. Due to biological effects described to some citrus species in this study our objectives were to analyze and compare the phytochemical composition and evaluate the anti-inflammatory effect of essential oils (EO) obtained from four different Citrus species. Mice were trea...

Context. Mergers of neutron stars (NS) and black holes (BH) are among the strongest sources of gravitational waves and are potential central engines for short gamma-ray bursts. Aims. We aim to compare the general relativistic (GR) results by other groups with Newtonian calculations of models with equivalent parameters. We vary the mass ratios between NS and BH and the compactness of the NS. The...

EOS (Economics via Object-oriented Simulation) is a computational framework for agent-based simulation, which was developed to simplify the process of constructing and running economic agent-based simulations. In this paper, we begin with an analysis of the previous versions of EOS, considering both their stability and microeconomic correctness. Having discovered problems with the stability and...

Duan, et al. (1992a, 1992b) developed an equation of state (EOS), similar to that of Lee and Kesler (1975), that describes P-V-T-X relations in the system H2O-CO2-CH4 over the range 50-1000 C / 0–1000 bar (0-1000 C / 08000 bar for single component fluids). An extensive comparison of values calculated with this EOS and experimental P-V-T-X and solvus data was published by Nieva and Barragán (200...
