Epidemiological modelling of vaccination and reduced funeral rites interventions on the peproduction number, R₀ of Ebola virus disease in West Africa (open access)

Epidemiological modelling of vaccination and reduced funeral rites interventions on the peproduction number, R₀ of Ebola virus disease in West Africa

This article examines the impacts of control measures on the reproduction number of the Ebola virus using a mathematically-based computational model. Specifically, the authors study the effects of vaccination and reduced funeral rites. This model could be used to forecast the duration of an Ebola epidemic in any country.

Failure analysis of an elbow tube fitting (open access)

Failure analysis of an elbow tube fitting

This article discusses elbow tube fitting. Abstract: Safe operation of machinery depends strongly on the design of the system and the employement of proper components and materials. Unique to fluid powered systems are the proper selection of hydraulic lines, fittings, and control valves. This paper describes the cause of fracture in an elbow tube fittings due to deficiencies in the dimensional design and materials selection. The investigation included metallography, fractography, hardness testing and metrology. The results showed that the material was low carbon steel subjected to cold forming and normalized annealing processes during tube production. There were dimensional variations in the tube and the material strength was low.

Metastability-assisted fatigue behavior in a friction stir processed dual-phase high entropy alloy (open access)

Metastability-assisted fatigue behavior in a friction stir processed dual-phase high entropy alloy

This article explores metastability-based high entropy alloy design which can open a new strategic path for designing high strength materials. However, high strength is always coupled with poor damage tolerance under cyclic loading conditions (fatigue). To overcome this drawback, the articles presents grain-refined Fe42Mn28Cr15Co10Si5 exhibiting significantly high fatigue strength as compared with leading transformation induced plasticity steels upon friction stir processing.
