Bioavailable testosterone and androgen receptor activation, but not total testosterone, are associated with muscle mass and strength in females

The Journal of Physiology, Volume 603, Issue 18, Page 5181-5208, September 15, 2025.
Abstract figure legend Twenty‐seven pre‐menopausal, untrained females performed a 12‐week resistance training programme to explore the association between androgen concentrations, androgen receptor signalling and skeletal muscle size and strength. Total testosterone was not associated with muscle mass or strength, nor with resistance training‐induced ...

Effect of Soft Reduction and Cast Speed on Macrostructure and Centre C Segregation of 42CrMo Steel Φ195 mm Bar Rolled from 410 mm x 530 mm Cast Bloom

Teshugang, 2021
The effects of soft reduction (0 ~ 8 mm) and casting speed (0.42 ~ 0.49 m/min) of cast bloom on macrostructure and segregation of 42CrMo steel Φ195 mm rolled product are tested. The results show at present process condition that when the superheat degree

Visualization of liquid ammonia spray using multi-hole injector

Nihon Kikai Gakkai ronbunshu
To reduce carbon dioxide emissions, carbon-free ammonia is being investigated as an alternative fuel for internal combustion engines. When injected into a low-pressure environment, liquid ammonia undergoes rapid vaporization (flash boiling) due to its ...

A Rotary Compressor-Accumulator Component Simulation Model in Consideration of (±) Suction Gas Superheat Degrees

, 2012
On the basis of the classic ARI compressor model, the mass flow-rate and input power were corrected with the level of suction gas superheat, especially the superheat degrees below zero. refrigerant dissolved in the oil pool, at the discharge pressure and the oil temperature, was calculated by means of the estimation model for refrigerant/oil mixture ...
