Blended learning compared to traditional learning for the acquisition of competencies in oral surgery by dental students: A randomized controlled trial.

Objective: To determine whether blended learning results in better educational outcomes compared to traditional learning in the acquisition of oral surgery technical skills for 4th-year undergraduate dental students.

Materials And Methods: Seventy-three students participated in this two-arm parallel randomized controlled trial. Only students in the blended learning group had access to the online preparation platform for oral surgery practical work (PW) on a pig's jaw and to the debriefing.

Modelling and techno-economic assessment of possible pathways from sewage sludge to green energy in India.

Efficient domestic wastewater management is essential for mitigating the impact of wastewater on human health and the environment. Wastewater management with conventional technologies generates sewage sludge. The present study considered a modelling approach to evaluate various processing pathways to produce energy from the sewage sludge.

Perspectives on consciousness in patients with disorders of consciousness from brain injury: group concept mapping study across clinic, research, and families.

Background: An effective healthcare system depends on clinic, research, and patient/relatives interactions. Such interactions may at their core be challenged by misalignments of concepts and the practices that constitute them. The concept of consciousness and what is experienced and understood as signs of consciousness in patients with severe acquired brain injury is one of these potential areas of misalignment.

An analysis of emission reduction strategy for light and heavy-duty vehicles pollutions in high spatial-temporal resolution and emission.

Traffic as the main source of urban air pollution created severe problems for human health and sustainability. To propose a bottom-up method in emissions reduction, accurate emission inventories of vehicles in a medium-sized city are developed. Traffic emission factors were obtained using traffic flow data, traffic control cameras, and International Vehicle Emission (IVE) model to calculate CO, VOCs, NOx, SOx, and PM of passenger cars, taxis, and urban buses emission inventory.

Impact of material emissions and sorption of volatile organic compounds on indoor air quality in a low energy building: Field measurements and modeling.

The assessment of VOC emission rates and sorption coefficients was performed for ten surfaces present within a classroom, using field and laboratory emission cells (FLEC) coupled to online and off-line VOC quantification techniques. A total of 21 identified VOCs were emitted by the different surfaces. VOC emission rates measured using PTR-ToF-MS were compared to gas chromatographic measurements.
