Despite increasingly widespread adoption of vacuum-assisted suspension systems in prosthetic clinical practices, there remain gaps in the body of scientific knowledge guiding clinicians' choices of existing products. In this study, we identified important pump-performance metrics and developed techniques to objectively characterize the evacuation performance of prosthetic vacuum pumps. The sens...

Abstract Ti–6Al–4V is the most commonly used titanium alloy in aerospace, marine, and biomedical applications. Due to properties of poor machinability conventional machining, Electrical Discharge Machining (EDM) considered a prospective alternative for machining this strategic material. This study aims at enhancing performance powder mixed EDM (PMEDM) with application two different types powder...

Distilled water in the laboratory is highly important since it a basic requirement lab work and/or research. The large use of distilled Faculty Mathematics and Natural Sciences University Lambung Mangkurat (FMIPA ULM) obliged to depend on its own by providing equipment produce water. efficiency low during producing one liter due 35 liters needed. Several studies have conducted focusing energy a...

Electrical failure during cardiopulmonary bypass (CPB) has previously been reported to occur in 1 of every 1500 cases. Most heart-lung machine pump consoles are equipped with built-in battery back-up units. Battery run times of these devices are variable and have not been reported. Different conditions of use can extend battery life in the event of electrical failure. This study was designed to...
