A survey of stress fractures occurring in recruits at the Depot of The Parachute Regiment was carried out over a one year period from July 1985 to August 1986. A total of 44 fractures in 36 soldiers were diagnosed. The incidence was thus 4.84%, much lower than that found in a recent prospective Israeli study. Only one case of progression to complete fracture was observed during the study. In co...

results all variables reached a peak at 1 minute post-jump. salivary alpha-amylase, galvanic skin responses and heart rate did not return to basal value at 90 minutes post-jump, while cortisol returned to basal value at 90 minutes post-jump. conclusions this evidence indicates that parachute jumping is accompanied by a dissociation of sns and hpa response patterns in novice parachutists, showin...

This article evaluated the functionality and reliability of personal airborne equipment backpack TL-98 before its launch in military parachute operations. An objective this project was verification TL-98’s characteristics which could be important terms safety operation parachute, i.e., during flight fall tests. A major effort within research focused on tests standard operational conditions. The...

Ahmed M, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-221348 Description A 47-year-old man presented with new onset exertional dyspnoea. He received a surgical repair of coarctation of the aorta (COA) at the age of 21 years and aortic root grafting with mechanical aortic valve replacement for type A aortic dissection and bicuspid aortic valve (BAV) at the age of 28 years. He had been otherwis...

We explore the utility of various sensors by recovering parachute-probe dynamics information from a package released from a small-scale, remotecontrolled airplane. The airdrops aid in the development of datasets for the exploration of planetary probe trajectory recovery algorithms, supplementing data collected from instrumented, full-scale tests and computer models.

The case is reported of an open injury of the right arm sustained during a parachute jump. The fracture was managed in the usual way with wound debridement, wound irrigation, skeletal stabilisation, and reconstruction of the soft tissues. Good shoulder and elbow function were achieved. The combined effort of an orthopaedic trauma surgeon and plastic surgeon is essential to improve outcomes in s...
