Concentration and content
One of the more frequent activities in health sciences is the measurement of biological quantities. Frequently, when reading biomedical books and journals some confusion on the metrological meaning of biological quantities related to the concepts 'concentration' and 'content' may be observed. Classically, a concentration is an amount of any type per volume of liquid or gas system, whereas conte...
متن کاملRheological and Physicochemical Properties of Honeys as a Function of Temperature, Concentration and Moisture Content
In this study the rheological and physicochemical properties of four types of honeys, two poly floral (Mountain, Forest) and two mono floral (Sunflower, Ivy), were investigated. Rheological characteristics of honeys were evaluated at different temperatures (10, 15, 20, 25 and 30ºC). All the honeys exhibited Newtonian behavior for shear rate in the range of 1.045-41.8 s-1. The viscosity of sampl...
متن کاملBridging kinematics and concentration content in a chaotic micromixer.
We analyze the mixing properties of the microfluidic herringbone configuration introduced to mix scalar substances in a narrow channel at low Reynolds but large Péclet numbers. Because of the grooves sculpted on the channel floor, substantial transverse motions are superimposed onto the usual longitudinal Poiseuille dispersion along the channel, whose impact on both the mixing rate and mixture ...
متن کاملon the equivalence of constructed-response and multiple-choice : stem-equivalent, stem non-equivalent but content equivalent, and stem and content non-equivalent items in reading comprehension using multifaceted rasch
the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...
Short communication: Effect of light and nitrogen concentration on the growth and lipid content of marine diatom, Chaetoceros calcitrans
The effects of light intensity (µ mol m-2 s-1) and different levels of Nitrogen was made on the biomass and lipid of microalgae Chaetoceros calcitrans under laboratory conditions in the north of Iran in 2016. The pure strand of C. calcitrans with F/2 media (8 sets of 3 flasks) were placed in front of the light source at values of 80, 160, and 240 µ mol m-2 s-1. The cell count was collected in ...
