I have to say that when I read the Editor's Journal, I was skeptical. The news that I would not be receiving OL as frequently was disappointing, as I am [...]

Having read Bill Heavey's account of his childhood with his 'brother' David E. Petzal in 'Sibling Riflery' (A Sportsman's Life), I must assume that he would find it great sport [...]

I have no problem with Phil Bourjaily reporting on the situation with lead ammunition (Shotguns), but all the effort spent on trying to ban lead shot could be better spent [...]

PARC has been a leading innovator in printed electronics with over a decade of experience in large area electronics, application of novel and current printing technology to industrial applications and the printing of electronic circuits and devices. We are currently applying this knowledge to the concept of printing multi-material 3 dimensional objects with electronic and/or mechanical functionality. The concept is to develop capability and provide means of manufacturing functional objects which may be difficult to manufacture or even not be manufacturable by other means. In this paper, we will outline the creation of a rapid digital manufacturing system and considerations for building such a "printer" with the ability to integrate a structural material with functional electronic materials. The printer incorporates inkjet and extrusion techniques on the same platform, along with an in-line UV-curing lamp. This platform enables a wide processing window for structural and electronic materials; i.e., it is capable of patterning inks with viscosity ranging from 1 to 25000 cP The printer has been optimized to yield smooth printed features (down to tens of microns) without implementing pressure-leveling steps.

ObjectiveThe quality of cardiopulmonary resuscitation (CPR) has been shown to affect the survival of out-of-hospital cardiac arrest cases (OHCA). There are various individual factors that can affect the quality of chest compression. We aimed to determine if age, gender and physical attributes (height, weight and BMI) affected the quality of chest compressions administered by laypersons during training.Design and methodsThe CPRcard™is a novel device that captures and provides real-time visual feedback on chest compression quality through a 2 metre display. We analysed data from our layperson CPR and AED training sessions from October 2015 to November 2015. Measurement parameters were adequate depth, adequate rate and flow fraction. Adequate depth was the percentage of total chest compressions with depth 5 cm. Adequate rate was the percentage of compression with rate between 100–120 chest compressions per minute. Flow fraction is the percentage of time chest compressions were performed without more than a 3 s pause. An adequate flow fraction target was >80%.Results77 participant’s data were analysed. 35% were male and 65% were female, with majority (34%) being 35–44 years old. The mean height was 1.63 m±0.10 m, mean weight 61.4 kg ±14.0 kg and mean BMI 23±4 kg/m2. Median adequate rate decreased significantly with age (p value=0.02). Median adequate depth and flow time showed no association with age (p=0.56, p=0.46 respectively). Males managed a significantly better median adequate depth (82.0% vs 56.0%, p value=0.01). There was no significant difference in chest compression quality with height, weight and BMI.ConclusionsOverall, at least 1 parameter of chest compression quality decreased with age, and was better in males than females. A possible application of these results is to have differences in training methods for different ages and sexes, targeting parameters that they are weaker at.
