The object of the research is Novoroscement plant. location plant shown below in Figure 1. cement located eastern part city. After reconstruction treatment facilities have been installed at and dust removal system clinker cooler was modernized. enterprise has got a lot advantages. It next to non-freezing sea, it convenient transport infrastructure (railways roads). Cement key building material ...

Glenoid component loosening is a common complication of total shoulder arthroplasty and has been associated with the progression of radiolucent lines at the glenoid bone-cement interface. Generation of heat during the exothermic reaction of cement curing may cause osteonecrosis of bone, potentially leading to the development of radiolucent lines. The purpose of this study was to measure the hea...

An obvious means to improve the fixation of a cancellous bone screw is to augment the surrounding bone with cement. Previous studies have shown that bone augmentation with Calcium Phosphate (CaP) cement significantly improves screw fixation. Nevertheless, quantitative data about the optimal distribution of CaP cement is not available. The present study aims to show the effect of cement distribu...

Purpose. To assess differences in dose distribution of a vertebral body injected with bone cement as calculated by radiation treatment planning system (RTPS) and actual dose distribution. Methods. We prepared two water-equivalent phantoms with cement, and the other two phantoms without cement. The bulk density of the bone cement was imported into RTPS to reduce error from high CT values. A dose...

Shiramizu K; Lovric V; Leung AMD; +Walsh WR Surgical & Orthopaedic Research Laboratories, University of New South Wales, Sydney, Australia [email protected] INTRODUCTION Deep infection after total joint replacement is a severe complication, and the use of antibiotic-loaded bone cement as a joint spacer is an established and efficient treatment method to treat infected arthroplasties. When pre...

The article shows the relation between sustainability and cement manufacture that can be obtained by replacement of clinker with limestone additive. This decreases use energy resources reduces CO2 emissions in production. issue partial Portland substitution finely ground production market-oriented types type CEM II is solved on plant PJSC "Ivano-Frankivsk Cement". indexes physical-mechanical te...

Study Design A biomechanical and radiographic study using vertebral analogues. Objectives Kyphoplasty and vertebroplasty are widely used techniques to alleviate pain in fractures secondary to osteoporosis. However, cement leakage toward vital structures like the spinal cord can be a major source of morbidity and even mortality. We define safe cement injection as the volume of the cement injecte...

The purpose of this study was to examine the effectiveness of a new glass polyphosphonate cement (Diamond) for orthodontic banding. Thirty-one subjects underwent in vivo testing to compare the failure rate of bands cemented using the test cement and bands cemented using a conventional glass polyalkenoate cement (Ketac-Cem) over a 6-month period at the beginning of active appliance therapy. In a...

BACKGROUND AND PURPOSE Adequate depth of cement penetration and cement mantle thickness is important for the durability of cemented cups. A flanged cup, as opposed to unflanged, has been suggested to give a more uniform cement mantle and superior cement pressurization, thus improving the depth of cement penetration. This hypothesis was tested experimentally. MATERIALS AND METHODS The same cup...

BACKGROUND Environmental asbestos pollution can cause malignant mesothelioma, but few studies have involved dose-response analyses with detailed information on occupational, domestic, and environmental exposures. OBJECTIVES In the present study, we examined the spatial variation of mesothelioma risk in an area with high levels of asbestos pollution from an industrial plant, adjusting for occu...
