Assessment of Brix refractometry to estimate immunoglobulin G concentration in beef cow colostrum
Journal of Veterinary Internal Medicine, 2020 Background Brix refractometry can be used to assess colostral immunoglobulin G (IgG) concentration, but studies identifying Brix percentages to detect high‐ and low‐IgG colostrum are lacking for beef cows and interlaboratory agreement is unknown ...

New polymers for phase partitioning [PDF]
The synthesizing of several polyethylene glycols having crown ethers attached is reported. This work led to the identification of three new polymer types which promise to be more effective at selectively binding specific cell types. Work was completed on

The Buoyant Behavior of Viral and Bacterial DNA in Alkaline CsCl [PDF]
, 1963 In equilibrium density gradient centrifugation, the banding polymer species is electrically neutral. The banding species for a negative polyelectrolyte with a polyanion P_(n)^(-z)n (where n is the degree of polymerization, and z the titration charge per

Journal of Food Process Engineering, Volume 49, Issue 3, March 2026.A model has been developed and validated with data from the sugar industry to determine the evaporation rate of discontinuous evaporating crystallizers. The results indicate that vapor nucleation on the surface of sucrose crystals is a significant factor, particularly in the context of low temperature differences in the calandria.

Block freeze-concentration of coffee extract: Effect of freezing and thawing stages on solute recovery and bioactive compounds [PDF]
, 2014 Coffee extract was freeze-concentrated using the total block technique. The effects of four parameters were evaluated: the initial coffee mass fraction (5 and 15% w/w), the cooling temperature ( 10 and 20 C), the heating temperature (20 and 40 C ...

Observation of non-local dielectric relaxation in glycerol
, 2011 Since its introduction, liquid viscosity and relaxation time $\tau$ have been considered to be an intrinsic property of the system that is essentially local in nature and therefore independent of system size.

Polarization-resolved sensing with tilted fiber Bragg gratings: theory and limits of detection [PDF]
, 2015 Polarization based sensing with tilted fiber Bragg grating (TFBG) sensors is analysed theoretically by two alternative approaches. The first method is based on tracking the grating transmission for two orthogonal states of linear polarized light that are

Determination of Lactose Concentration in Milk Serum by Refractometry and Polarimetry
Scientific Papers Animal Science and Biotechnologies, 2023 The research had in view to evaluate and compare two instrumental techniques used for the determination of milk lactose. Refractometric and polarimetric measurements were carried out on milk serum obtained after precipitation of casein by two different ...

Subjective method of refractometry and depth of focus
Journal of Optometry, 2012 Purpose: To study the impact of the depth of focus on subjective refraction and distribution of myopic and hyperopic refractions. Methods: A total of 450 eyes of 305 subjects in the age range of 23–34 years were recruited for the study. A distribution of
