Determination of isosmolar blood anticoagulant solutions by the freezing-point method.
LTHOUGH SUITABLE CONCENTRATIONS of many anticoagulants have been determined for mammalian blood, isosmolar concentrations are not generally available among vertebrates. In some instances the correct concentrations may be computed from known equations (1) or from known freezing-point depressions (ATs) at specific concentrations (2). The data are still fragmentary. In the present study, ATs cover...
متن کاملA new method of freezing-point determination for small quantities.
To a very large extent progress in the field of invertebrate physiology is a measure of progress in the technique of manipulating small structures and analysing small samples. Within this field the study of osmotic regulation is no exception. Krogh (1938) has summarized the known methods of measuring osmotic pressure, applicable to quantities of fluid of the order of O-I-I-O cu.mm. The freezing...
متن کاملOsmotic coefficient of aqueous solutions of cyclohexylsulfamic Acid at the freezing point of solutions.
The osmotic coefficient of aqueous solutions of cyclohexylsulfamic acid was determined by freezing point measurements up to the molality 0.65 mol kg-1. The osmotic coefficients were fitted to the Pitzer equation, and ion interaction parameters α1, β(0) and β(1) were evaluated. The mean ion activity coefficient of the solute was calculated, and the non-ideal behaviour of the system investigated ...
متن کاملdetermination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
15 صفحه اولFreezing Point Depression of Plasma ‡
In an earlier paper2 we have reported results demonstrating that changing the concentrations of the carbon dioxide and oxygen with which the bloods of sheep and goats are equilibrated has a measurable effect on the total osmotic pressure of the true plasma. At constant oxygenation the osmotic pressure of the true plasma is increased 0.9 milliosmoles/Kg H20 for each millimole of C02/Kg H20 added...
