There are some theoretical arguments related to interpreting the adiabatic compressibility (beta(s)) of a protein determined from the sound velocity and the difference between beta(s) and isothermal compressibility (beta(T)). To address these problems experimentally, we constructed a high-pressure oscillating densitometer and used it to measure the apparent specific volume of bovine serum album...

In a procedure for the routine electrophoretic fractionation of serum glycoproteinson cellulose acetate, electrophoretic fractionation is followed by staining utilizing the periodicacid-Schiff reaction. The patterns are scannedwith a recording densitometer and simultaneouslyquantitated with an attached integrator. For 100 healthy blood donors,the meansand standarddeviationswere: albumin, 10.9±1...

Non-invasive measurement of body composition provides advantages in growth studies compared to conventional techniques. The same individual can be measured several times, the measurement is faster, and the number of pigs required as well as the random effect of animal are reduced. The aim of the present study was to determine the composition of the half carcass and of the ham/shank region by a ...

Density, temperature, salinity, and hydraulic head are physical scalars governing the dynamics of aquatic systems. In coastal aquifers, lakes, oceans, salinity is measured with conductivity sensors, temperature thermistors, density calculated. However, in hypersaline brines, (and density) cannot be determined by measurements due to its high ionic strength. Here, we resolve using a hydrostatic d...
