Recycling of by-products of the steelmaking process in electric arc (EAF) furnaces is an important activity from the perspective of environmental protection as well as the steelmaking industry itself. This article is a discussion concerning the selected research results in terms of utilisation of steelmaking dusts containing 4 12 % of zinc in manufacture of cement bricks, ceramic construction m...

Total knee replacement (TKR) is now recognized as a viable surgical option for managing dogs with severe to end-stage stifle joint osteoarthritis. The goal of this presentation is to briefly review the biomechanics of the normal stifle joint and to describe how this information has been used to guide the design and manufacture of contemporary TKR implants. The influence of implant design, surgi...

Concrete is probably the most extensively used construction material in the world. The addition of mineral admixture in cement has dramatically increased along with the development of concrete industry, due to the consideration of cost saving, energy saving, environmental protection and conservation of resources. However, environmental concerns both in terms of damage caused by the extraction o...

Barite plaster has been largely used as shielding material in installations housing gamma radiation sources as well as x-ray generating equipment, in order to minimize exposure to individuals. However, some physical characteristics, such as density, plasticity, resistance to compression and radiation attenuation for the different types of barite plaster commercially available in Brazil are not ...

Nowadays, cement manufacture is one of the most polluting worldwide industrial sectors. In order to reduce its CO₂ emissions, the clinker replacement by ground granulated blast-furnace slag and fly ash is becoming increasingly common. Both additions are well-studied when the hardening conditions of cementitious materials are optimum. Therefore, the main objective of this research was to study t...

Concrete is one of the most widely used construction material in today’s world. Cement is one of the essential constituents of the concrete. Environmental issues are also playing a vital role in today’s world, the production of cement one of the major constituent of concrete leads to release the of a significant amount of carbon dioxide a greenhouse gas contributing 7% of greenhouse gas emissio...

Hydrogen peroxide has been used for decades as an effervescent haemostatic agent in arthroplasty. Recently it has been shown to adversely affect the material properties of PMMA. We aim to assess whether any such deleterious effects are demonstrated in an experimental model which mimics the clinical use of hydrogen peroxide. Matched pairs of cancellous bone samples were treated with a swab soake...

The aim of this study was to manufacture and test, in vitro, a novel modification to provide fluoride-releasing orthodontic brackets. Thirty-two orthodontic brackets were drilled to produce a recess (approximately 1.3 mm in diameter and 0.7 mm in depth) at the centre of the bracket base. Four materials, with and without the addition of sodium fluoride, a glass ionomer cement (Ketac Cem micro), ...

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...
