Prosthodontics is a constantly evolving branch of dentistry as result innovative treatment options based on new materials, techniques, and technologies, with composite material revolutionised everything. With the advent fiber reinforcement, it has further increased potential uses composites within dentistry. Fiber reinforced materials have highly favourable mechanical properties their strength ...

Corrosion and scaling are among the problems that may arise when storing water in tanks. Several factors affect corrosion of water, which include pH, temperature, alkalinity, Ca2+ hardness, TDS, concentrations Cl–, SO42–, CO32–, HCO3–. Also, several indices can be measured using these properties such as Langelier saturation index, Ryznar Aggressive Larson, Scold quality Puckorius index. These i...

Environmental water’s corrosion evaluation of concrete (structure), steel bars and structures in reinforced is an item engineering investigation. Therefore, environmental water samples are used for chemical composition testing during the investigation carried out according to regulations. Evaluation very necessary. Taking Lai Hydropower Station dam site as example, through test results samples,...

The furnace gas resulting from the electrothermal production of yellow phosphorus contains up to 95% CO, 2% O2, H2, and 0.3–4.0% impurities, including phosphine (PH3), (P4), hydrogen sulphide (H2S), which are characterized by flammability, explosion hazardousness, corrosiveness, high toxicity. presence toxic impurities does not allow use waste gases production, mainly composed valuable carbon m...

This note presents a case study which aimed to identify the environmental effects that may cause or accelerate corrosion of helical steel piles installed in typical site Brazilian unsaturated tropical soil. For this study, an experimental investigation was carried out based on detailed examination two piles, fabricated with weathering steel, exhumed after approximately four years installation. ...

The selection of fuel for a Combined Heat and Power (CHP) plant can vary over time. By choosing less expensive fuels, operation costs are reduced, however, cheaper fuels generally increase corrosion maintenance costs. corrosiveness different has been studied extensively while how the current attack is influenced by history, i.e. previous deposit build-up oxide scale formation, studied. This phe...
