Theoretical Analysis for Basic Dynamic Load Rating and Life Formula of Ball Screw
Journal of the Japan Society for Precision Engineering Contributed Papers, 2006 The existing method of calculation for the basic dynamic load rating mentioned in the ISO standard is based on the method used for the angular contact ball bearing and does not align with the one used for the linear bearing. The unit for the rating life, i.e., the Unit Running Life (URL) is defined in terms of 106 rev.

Effects of advanced life support versus basic life support on the mortality rates of patients with trauma in prehospital settings: a study protocol for a systematic review and meta-analysis [PDF]
BMJ Open, 2017 Introduction Advanced life support (ALS) is thought to be associated with improved survival in prehospital trauma care when compared with basic life support (BLS). However, evidence on the benefits of prehospital ALS for patients with trauma is controversial.
