Blunt chest injury is commonly observed in the Pediatric Emergency Department and Intensive Care Unit since up to 30% of children with traumatic injury sustain injury to the thorax. Differently from adults, who present with concomitant rib or sternoclavicular fractures in 70% of cases, more than half of childhood chest injuries occur without any bone fracture, mostly causing lung contusions. This lower rate of rib fractures and near absence of flail chest in children may be due to greater elasticity of the pediatric cartilaginous and bony skeleton. Whenever a rib fracture is present, underlying complications should be evaluated carefully (i.e., air leaks or blood effusions). Depending on the trauma mechanism, even minor injuries should raise the suspicion of pathologic bone fractures.

In response to the intensifying competition in the mold market and the increasingly stringent specifications of die forgings, the existing 55NiCrMoV7 (MES 1 steel) material can no longer meet the elevated demands of customers. Consequently, this study systematically optimizes the alloy composition of MES 1 steel by precisely adjusting the molybdenum (Mo) and vanadium (V) contents. The primary objective is to significantly enhance the microstructure and thermal-mechanical fatigue performance of the steel, thereby developing a high-performance, long-life hot working die steel designated as MES 2 steel.

Surfactin is a biosurfactant produced by many strains with a wide variety of functions from lowering surface tension to allowing motility of bacterial swarms, acting as a signaling molecule, and even exhibiting antimicrobial activities. However, the impact of surfactin during biofilm formation has been debated with variable findings between studies depending on the experimental conditions. B.

Background Web-based, testing for sexually transmitted infections (STI) is becoming increasingly available. However, treatment pathways from web-based services are often not well-coordinated, contributing to treatment delays and access gaps. This study investigated clinician perspectives on building service linkages with a new, web-based, STI testing service in Victoria, Australia.

Alkali-surfactant-polymer (ASP) flooding can reduce oil-water interfacial tension to ultralow values and mobilize oil in petroleum reservoirs. Surfactant is consumed by adsorption/retention which is significant in clay-rich reservoirs. Alkali can be added to surfactant-polymer formulations to minimize surfactant adsorption.

Purpose: An assistive technology ecosystem requires co-ordinated collaboration between policy, products, provision processes, and personnel. A needs assessment was conducted of the assistive technology sector in Queensland to examine these components from the perspective of all key stakeholders. This paper reports the findings of the expressed needs of the assistive technology sector as experienced by the AT advisors and suppliers.
