Objective To test whether standard information for patients using Crunchie and Aero chocolate bars to explain bone health and risk of fracture is robust. Design Observational study. Setting Domestic kitchen in rural west Wales. Participants 10 Crunchie bars and 10 Aero bars. Main outcome measure Fracture after falls from varying heights. Results Both Crunchie and Aero bars exhibited the same T ...

Aerodynamics in turbo-components and matched combustor characteristics relating to the design of ultramicro gas turbines (UMGT) were presented. Some detailed analysis were provided for the effects of heat transfer, tip clearance and geometrical restriction imposed to UMGT flow passages, as well as a leading concept of combustor design to achieve micro flame structure for enhanced efficiency and...

This paper presents experimental studies of aero-optical distortions due to a turbulent boundary layer over a range of subsonic speeds with the underlying wall both heated above and cooled below the adiabatic wall temperature. A statistical scaling model, based on Extended Strong Reynolds Analogy is derived and shown to correctly predict experimentally-observed results. The temperature mismatch...

We follow up on our research demonstrating that aerotactile information can enhance or interfere with accurate auditory perception, even among uninformed and untrained perceivers [1]. Mimicking aspiration, we applied slight, inaudible air puffs on participants’ skin at the ankle, simultaneously with syllables beginning with aspirated (‘pa’, ‘ta’) and unaspirated (‘ba’, ‘da’) stops, dividing the...

This article describes the research stimulated by a fundamental shift that is occurring in the manufacture and marketing of aero engines for commercial and defense purposes, away from the selling of products to the provision of services. This research was undertaken in an aerospace company, which designs and manufactures aero engines and also offers contracts, under which it remains responsible...

Metastatic involvement of the heart is a rare occurrence and remains undiagnosed until autopsy. In some instances, patients may have cardiac symptoms, leading to ante-mortem diagnosis. Although most primary cancers have been documented to metastasize to heart, the existing literature on cancers of upper aero-digestive tract is an exception, with only a few reports. We report four cases of upper...
