Nickel-titanium shape memory alloys have been widely used in medical fields due to their unique shape memory effect, superelasticity, corrosion resistance and biocompatibility.However, there are still many processing difficulties to achieve required machined surface quality due to their high toughness and low elasticity.This paper proposes a sequen

Weather is a potentially important determinant of physical activity.Little work has been done examining the relationship between weather and physical activity, and potential modifiers of any relationship in older people.We therefore examined the relationship between weather and physical activity in a cohort of older community-dwelling people.We ana

It is a well-known fact that the relative humidity of air may have an influence on the build-up of static electricity on equipment, installations, packages, personnel, etc.However the questions arise whether in industrial practice the increase of the relative humidity of air is sufficiently effective to prevent ignition of explosive atmospheres by

Abstract Background Respectful maternity care forms the foundation of maternity services; however, delivery of dignified, efficient, and effective care in these settings remains inconsistent.Research has identified several factors that influence respectful maternity care.To understand the South African context, these factors were explored and descr

In the development of practically all potash salt deposits, the study of gas-dynamic phenomena (GDP) is one of Pickle the most difficult tasks to ensure mining safety.Sudden salt and gas outbursts, dynamic breakdown, which are accompanied by intense gas release and possible broken rock carry-over into the mine workings, are associated with GDP.Geol
