Determinants of bioelectrical phase angle in disease [PDF]

British Journal of Nutrition, 2011
Phase angle (PhA), a parameter of bioelectrical impedance analysis, is a well-known predictor of morbidity and mortality in various diseases. The causes of decreased PhA are, however, not yet completely understood. We therefore investigated determinants of PhA in 777 hospitalised patients in a retrospective analysis.

Adsorption ability, stability and corrosion inhibition mechanism of phoenix dactylifera extrat on mild steel

Materials Research Express, 2020
Adsorption ability, stability and corrosion inhibition of phoenix dactylifera (date palm) seed extract (PDSE) as a natural corrosion inhibitor were studied on mild steel (MS) in 1 M HCl solution after different exposure times.

Phase Angle Cut-Off Points and Their Association With Sarcopenia and Frailty in Adults of 50–64 Years Old and Older Adults in Mexico City

Frontiers in Medicine, 2021
Background: In recent studies, the usefulness of the phase angle (PA) to assess geriatric conditions such as sarcopenia and frailty has been evaluated.

Parametric Study of an Air Charged Franchot Engine with Novel Hot and Cold Isothermalizers

Inventions, 2017
The Stirling engine is an external combustion engine that uses heat exchangers to enhance the addition and removal of energy. This makes the engine power-dense but expensive, less efficient and complicated. In this contribution, the Stirling engine based

Bioelectrical Impedance Analysis Derived-Phase Angle as a Pragmatic Tool to Detect Protein Energy Wasting among Multi-Ethnic Hemodialysis Patients

Diagnostics, 2021
Protein-energy wasting (PEW) is a devastating metabolic derangement that leads to increased morbidity and mortality in hemodialysis (HD) patients. This study aimed to determine the diagnostic test accuracy of bioelectrical impedance analysis derived ...

Bioelectrical impedance phase angle in sport: a systematic review

Journal of the International Society of Sports Nutrition, 2019
Background Phase angle (PhA) is a raw BIA variable that has been gaining attention in recent years because it is supposed to be an index of the ratio between extracellular and intracellular water, body cell mass, and cellular integrity.

Changes in total and segmental bioelectrical resistance are correlated with whole-body and segmental changes in lean soft tissue following a resistance training intervention

Journal of the International Society of Sports Nutrition, 2019
Background Raw bioelectrical values can be used to assess physiological outcomes, though limited information is available concerning the relationships between changes in these values and changes in other variables of interest.

Can Well-sampled Phase Curves Be Used to Infer Asteroid Spectral Features?

The Planetary Science Journal
The relationship of an asteroid's reduced magnitude to its phase has a long history of study. Included in this history have been efforts to study the correlation between these parameters and spectral type.

Phase shifting angle interferometer

Metrologia, 2023
Abstract A phase shifting Twymann-Green interferometer for the measurement of plane angle has been developed and characterized using a small-angle generator directly traceable to the definition of the radian. The impact of surface form on the measured angle was explored using a simple deformable mirror.
