Workers in Devki are exposed to several occupational hazards resulting in an average of three workers going on sick leave monthly. The management sought to reduce these incidences using a leading indicator through Safety Culture. Determining the safety culture was the main study objective. Independent variables were artefacts, espoused values and basic assumptions. The study made use of an analytical cross sectional design. The study population was 800 permanent employees from which a sample of ...

Diclofenac (DCF) is a non-steroidal anti-inflammatory drug (NSAID) used to relieve pain in joint-related diseases. It is not completely metabolized after consumption and cannot be easily removed using conventional wastewater treatment. DCF has been detected in water bodies and may pose chronic effects on the endocrines of living organisms even at low-level exposure. Heterogeneous photocatalysis provides an alternative and efficient method of degrading DCF. In this study, the photocatalytic remov...

As one of the magnetorheological materials, magnetorheological elastomer (MRE) possesses unique solid properties that give it excellent mechanical properties. In the presence of an external magnetic field, the force, magnetic and electrical properties of the MRE also vary with the magnitude and direction of the magnetic field. This has led to a wide range of applications in the field of shock absorbers. This paper presents the properties of magnetorheological elastomers and the latest research s...

In this paper, HSC software was used to perform a thermodynamic analysis of A5083/ZrO₂ metal matrix composite to predict the phases which formed during the manufacturing processes (vortex method). The base matrix was purchased commercially and the zirconia particles were extracted from Egyptian zircon as a reinforcing material by alkaline fusion technique. The base material was melted in an electric furnace at 750°C, and the extracted zirconia particles were added while stirring. ...

Mineral coal presents a historical chronology to society, mainly regarding energy generation, and is outstanding in relation to oil when the subject is electricity generation, besides being utilized in the cosmetics and coal gas industry. Thus, the production chain that uses mineral coal must be validated for quality, considering specific prerequisites that show the positivity of this analysis. For this purpose, the present study was characterized by a Systematic Literature Review (SLR), aiming ...
