An investigation of chirped fibre Bragg gratings Fabry-Perot interferometer for sensing applications [PDF]

, 2005
Fibre interferometer configurations such as the Michelson and Fabry-Perot (FP) have been formed using uniformed and chirped Fibre Bragg Gratings (FBG) acting as partial reflectors. As well as increasing the dynamic range of the interferometer, chirped

Locally pressed fibre Bragg grating pressure sensor [PDF]

, 2006
A spectral-hole created by locally pressing a fibre Bragg grating exhibited a wavelength-shift within the FBG bandwidth. A sensitivity of 74.3pm/(N/mm) was obtained for pressure applied along the slow axis of a high birefringence ...

Effect of Aphanizomenon flos-aquae (AFA) or Orlistat on hyperlipidemic adult male Albino rats [PDF]

Journal of Medical and Life Science, 2019
Background: Hyperlipidemia, hyperlipoproteinemia, or dyslipidemia means the presence of elevated or abnormal levels of lipids and/or lipoproteins in the blood. Hyperlipoproteinemia happens when there are large amounts of lipids (fats) in the bloodstream.
