Quantitative photoplethysmography: Lambert-Beer law or inverse function incorporating light scatter
Journal of Biomedical Engineering, 1993Finger blood volume is commonly determined from measurement of infra-red (IR) light transmittance using the Lambert-Beer law of light absorption derived for use in non-scattering media, even when such transmission involves light scatter around the phalangeal bone. Simultaneous IR transmittance and finger volume were measured over the full dynamic range

Applied Spectroscopy, 1998
Beer's law is obeyed when the measured value of absorbance varies linearly with concentration in the absence of chemical effects. The absorbance range over which bands measured on any type of spectrometer obey Beer's law depends on the ratio of the resolution to the full width at half-height of the analytical band, often called the resolution ...

Pixel-wise modified Beer-Lambert model for intraoperative functional brain mapping
Clinical and Preclinical Optical Diagnostics II, 2019A RGB camera and a continuous wave white light illumination is a suitable approach to intraoperatively localize the sensory and motor areas of the patient brain. The analysis of the reflectance spectra through the modified Beer-Lambert law enables us to measure the concentration changes of oxygenated and deoxygenated hemoglobin during the video ...

Functional traits of craft beers
The chapter addresses the synergies of nutrition, health, and consumer preferences in the context of evolving craft beer trends. Malted-based beverages have emerged as functional and probiotic systems due to their rich nutritional profile, including soluble fibers and phytoestrogens.openaire +1 more source
Beer-Sheva, capital of the Negev desert ?Function and internal structure
GeoJournal, 1978The rapid growth and development in modern times of Beer-Sheva, the city of the Patriarchs, and its transformation into a major centre of growth in the southern desert part of Israel has intrigued experts who deal with urban growth and development. In this paper we examine the major factors that have contributed to the city's place and function in ...

Alcohol consumption has a long history in human existence and is implicated as one of the major risk factors in the development of liver diseases. The comparative impact of locally made (burukutu and pito) sorghum-based beer and Star Larger beer on the liver biomarkers of albino rats was investigated. 35 albino rats were grouped into 7 groups of 5 rats

Beer, Hot Dogs and Politics: The Vocative Function of Medellín’s voseo
Bulletin of Hispanic Studies, 2018Voseo is widely used in speech in Medellin, Colombia, but it is non-standard for writing. Weyers (2016) finds that written voseo has a growing presence. This study examines the vocative use of vos in public domains. The objective of the written vos goes beyond friendly address.
