Emergency department overcrowding is a global issue that poses a great threat to patient health and safety. The timeliness of medical services provided to patients is crucial to emergency departments as it directly impacts the mortality and morbidity of urgent patients. However, critical resources (e.g., doctors and nurses) are typically constraine...
The ability of cellular concrete waste (CC) to remove hydrogen sulfide (H2S) from a mimic biogas composed of nitrogen, oxygen and H2S was investigated using abiotic filtration systems for H2S concentration up to 1500 mg m−3 and Empty Bed Residence Time (EBRT) ranging from 30 to 180 s. The influence of the humidity of the material in H2S removal was...
The damage layer produced during the Niobium sheets and cavity fabrication processes is one of the main reasons why cavities have to undergo an extensive surface preparation process to recover optimal superconducting properties. Today, this includes the use of lengthy, costly, and dangerous conventional polishing techniques as buffered chemical pol...
The melting of an amorphous polymer filament through the hot end of a material extrusion process is addressed using computational multiphase fluid dynamics coupled to heat transfer. Only the flow through the heat block is investigated. The air gap between the filament and the interior of the extruder is accounted for. The polymer/air interface is i...

Data redundancy and data loss are relevant issues in condition monitoring. Sampling strategies for segment intervals can address these at the source, but do not receive the attention they deserve. Currently, the sampling methods in relevant research lack sufficient adaptability to the condition. In this paper, an adaptive sampling framework of segm...

Current methods for ergonomic assessment often use video-analysis to estimate wrist postures during occupational tasks. Wearable sensing and machine learning have the potential to automate this tedious task, and in doing so greatly extend the amount of data available to clinicians and researchers. A method of predicting wrist posture from inertial ...
This work investigates the drying of yacón (Smallanthus sonchifolius), a source of fructooligosaccharides and inulin, two prebiotic compounds. Experiments were performed using an in-house device consisting of a magnetic suspension balance coupled to a drying chamber and an in-situ shadowgraphy system. This allowed the continuous acquisition of mass...
Hydrate formation is a threat to the safety of petroleum transport in flow lines due to the risk of plugging. In this work, conceptual mechanisms of hydrate formation and plugging in oil-water systems are proposed, based on flow loop tests at 30%, 50% and 80% water cut (water fraction). The experiments were conducted with Kerdane oil, water (with 3...
In this review article, the Kinetics Committee of the International Confederation for Thermal Analysis and Calorimetry (ICTAC) delivers a collection of recommendations for the kinetic analysis of thermal decomposition processes. These recommendations specifically focus on the thermal decomposition processes in inorganic, organic, and polymeric mate...
The fluidization of short Hi Nicalon S fibers was investigated before considering CVD coatings with controlled composition and thicknesses. The fluidization of a short fiber batch alone being delicate and not reproducible, the study consisted in comparing the hydrodynamic behavior of a powder alone, to that of a short fiber/powder mixture. The flui...
