Visio Scan VC98, Corneometer MPA 5 and Tewameter MPA 5 [PDF]

open access: diamondAfrican Journal of Pharmacy and Pharmacology, 2012
Human skin is the largest exposed area of our body. There are number of physiological changes which may occur in response to internal or external sources. Biophysical techniques have been extensively employed to study any changes in human skin physiology. Usually these bioengineering techniques are equipped with non-invasive probes.

Sound reduction in heat exchanger modules by integrating plate absorbers with sub-millimeter openings

open access: yesActa Acustica, 2021
In air conditioning systems heat exchangers are frequently installed upstream of ventilators. These modules are part of the daily life of humans and should therefore create an environment that is as quiet as possible.

Should physical activity recommendations be ethnicity-specific? Evidence from a cross-sectional study of south Asian and European men [PDF]

open access: yes, 2013
Background Expert bodies and health organisations recommend that adults undertake at least 150 min.week−1 of moderate-intensity physical activity (MPA). However, the underpinning data largely emanate from studies of populations of European descent. It
