This study describes a new tanks-in-series model for analyzing non-ideal flow regimes in single-strand tundish. The tundish was divided into two interconnected tanks, namely an inlet tank and outlet tank. A water experiment carried out to separately measure the residence-time distribution (RTD) of tanks. Drift beads were adopted simulate non-metallic inclusions molten steel. Dead volume fractio...

Erosion of refractory lining due to flow induced wall shear stress is one among severe problems that shop floor personnel face in continuous casting tundish operation. It decreases the life and increases overall operational cost. Wall turbulent major factors erosion tundish. Inclusion generation creates surface defects may lead rejection final products. Turbulent inhibitor box (TIB) helps reduc...

Abstract Control of calcium treatment in steel is challenging due to the reactivity Ca and difficulty measuring total oxygen in-process make actionable decisions. In this work, a method combining statistics process engineering are developed using partial least squares regression (PLS) predict non-metallic inclusion content (oxides CaS) composition at end ladle tundish extensive data SEM/EDS-bas...

BACKGROUND Corns are a common foot problem and surveys have indicated that between 14-48% of people suffer from them. Many of these will seek podiatry treatment, however there is little evidence to indicate which current treatments provide long term resolution. This study compared 'usual' treatment (enucleation with a scalpel) with the application of 40% salicylic acid plasters to corns to inve...

INTRODUCTION Plaster of Paris (PoP) impregnated bandages have been used to maintain the position of bones and joints for over a century. Classically, wool dressing is applied to the limb before the PoP, which can then be moulded to the desired shape. A modification of this practice is to wrap the PoP bandages circumferentially in cotton before wetting and applying to the patient in an attempt t...

BACKGROUND Distal radius fractures are among the most prevalent fractures predictive of probable occurrence of other osteoporotic fractures. They are treated via a variety of methods, but the best treatment has not been defined yet. OBJECTIVES This study was performed to compare the results of open reduction and internal fixation with locking plates versus the pin and plaster method. MATERI...

BACKGROUND Burns and pressure sores are common injuries during cast application. Various factors such as water temperature, padding, and cast material layers may play a role in these injuries; however, the effect of cast molding on temperatures and pressures has not been investigated. This raises the following questions, does the application of molding during cast application: (1) alter skin le...

This research evaluates the behavior of plaster with a water-repellent additive when submitted to natural aging process. Casting and silane/siloxane-based were used as materials. The water/plaster ratio was set at 0.7 contents 0.2% 0.4% used, in relation mass. Plaster pastes without (reference) containing mass evaluated ‘zero’ age after 30, 60, 90, 120, 150 days aging. After aging, it observed ...
