Locomotor muscle dysfunction and rehabilitative exercise training in fibrotic interstitial lung disease: Where are we at and where could we go?

open access: yesExperimental Physiology, EarlyView.
Abstract Exercise limitation is a cardinal feature of fibrotic interstitial lung disease arising from pulmonary gas exchange, respiratory mechanical and cardio‐circulatory abnormalities. More recently, it has been recognized that impairment in locomotor muscle function (e.g., reduced muscle mass/strength or heightened fatigability) might also play a ...

Conceptual design and analysis of a large antenna utilizing electrostatic membrane management [PDF]

open access: yes
Conceptual designs and associated technologies for deployment 100 m class radiometer antennas were developed. An electrostatically suspended and controlled membrane mirror and the supporting structure are discussed.

50% body weight loading reduces stature increases and lumbar disc expansion from 4 h hyper‐buoyancy floatation versus 15 min sitting upright

open access: yesExperimental Physiology, EarlyView.
Abstract Microgravity is associated with stature increases, back pain and post‐flight intervertebral disc (IVD) herniation. This study aims to determine whether 30 s seated 50% body weight (BW) axial loading is comparable to 15 min sitting upright in 1 g upon changes in stature, anterior lumbar IVD height (via ultrasound), passive vertebral stiffness ...

Improved oil-off survivability of tapered roller bearings [PDF]

open access: yes
The aim of this program is to improve the oil-off survivability of a tapered roller bearing when applied to a helicopter transmission, since the tapered bearing has shown a performance advantage in this application.

Sex differences in loop gain measured via superimposed end‐expiratory breath holds and inspired steady‐state hypoxia

open access: yesExperimental Physiology, EarlyView.
Abstract Acute low oxygen exposure (hypoxia) elicits a hypoxic ventilatory response (HVR), which increases ventilation and mitigates hypoxaemia. During sustained exposure to hypoxia, ventilatory acclimatization increases peripheral chemoreflex (HVR) sensitivity or chemoreflex loop gain (LG).

Performance of computer-optimized tapered-roller bearings to 2.4 million DN [PDF]

open access: yes
The performance of 120.65 mm bore high speed design tapered roller bearings was investigated at shaft speeds to 20,000 rpm under combined thrust and radial load. The test bearing design was computer optimized for high speed operation.

mTOR blockade prevents progressive proteinuria but induces hyperglycaemia in obese Dahl salt‐sensitive rats before puberty

open access: yesExperimental Physiology, EarlyView.
Abstract Previous studies have demonstrated that mammalian target of rapamycin (mTOR) activity is significantly increased in the kidneys of Dahl salt‐sensitive (SS) rats during the development of renal injury. Therefore, in the present study we examined whether blockade of mTOR with rapamycin inhibits renal injury in Dahl salt‐sensitive leptin receptor
