It is shown that absorption of the excitation light can lead to substantial systematic errors in fluorescence measurements of equilibrium constants for formation of protein-ligand complexes. The assumptions about the optical arrangement of the fluorescence spectrometer involved in the calculation of the correction of this absorption are discussed. A general semiempirical correction procedure wh...

We have investigated the skin absorption of liquid toluene and of solutions of toluene in water by the methods we used for ethylbenzene (Dutkiewicz and Tyras, I967). The absorption rate of liquid toluene was I4-23 mg./cm.2/hr in I0 estimations on nine subjects. Absorption of toluene from an aqueous solution was proportional to the concentration (Figure). For equal concentrations the rate was on...

This study was to develop a radiation sterilized polypropylene/ethylene-propylene diene monomer (PP/EPDM) binary blends using melt blending and the mechanical properties of were studied. The PP/EPDM prepared in ratios 80:20, 60:40, 50:50, 40:60 20:80. then compressed for 12 minutes Hot Cold Press machine cut into 1mm, 3mm 6mm thickness tensile test, impact hardness test Fourier Transform Infrar...

The effect of the Finnish sauna on insulin absorption from a subcutaneous injection site was examined in eight insulin-dependent diabetic patients by measuring externally the disappearance rate of 125I-labelled rapid-acting insulin. The sauna (twice for 25 minutes at 85 degrees C) accelerated insulin absorption by 110% as compared with room temperature (p < 0.01). After the sauna blood glucose ...
