Since sub-endocardial ischemia is the consequence of a discrepancy between the blood demand and supply of oxygen at this level, the study of the myocardial performance by the measurement of the endocardial viability ratio (E.V.R.) is both useful and possible during anesthesia. E.V.R. is the ratio between the oxygen supply and demand of the myocardium. It is equal to the diastolic pressure time index (D.P.T.I.) over the tension time index (T.T.I.). Measurements are made at different times, by means of the arterial pressure and the left atrial pressure, as well as with the Datascope-E.V.R. Computer. During gradual morphine administration (0.5-1-1.5 mg/kg) and if no major surgical stress occurs, E.V.R. remains excellent and stable (1.46 - 1.48 - 1.43). It deteriorates more or less (1.29 - 1.09) during tachycardia or hypertension. Within the hour following the end of extracorporeal circulation, E.V.R. significantly improves (1.04 - 1.06 - 1.09 - 1.23). Although E.V.R. measurement is easy during cardiac surgery, it is impossible to carry out in case of arrhythmia. While morphine anesthesia induces no variation in E.V.R., tachycardia or hypertension require the addition of therapeutic drug. Within one hour following the end of extra-corporeal circulation, E.V.R. measurement shows improved endocardial viability, although the hemodynamic parameters undergo no significant change. [less ▲]

Several ring tests have been organized by the International Organisotion for Standardization (lSO) and the Measurement ônd Testing Programme (BCR) for improving glucosinolote methods Finally, HPLC of desulphoglucosinolates is recommended by lSO, the European Committee for Standardizotion (CEN), and the European Commission (EC) as the official method. X-ray fluorescence has also become particularly common for fast analysis. After checking stability of intact glucosinolates in whole rapeseeds, the BCR has three reference materials (CRM 366, CRM 190, CRM 367) avai able, certified for their total glucosinolate and sulphur contents. Currently, the Measurement and Testing Programme is supporting a research project concerning the stdbility of desulphoglucosinolates and intact glucosinolates extracts. At the present time, best results were observed with lyophilized extracts sealed in brown glass ampoules and stored at 18'C. [less ▲]

This study aimed at testing whether 12 rather than 26 plasma glucose and insulin determinations can be used to calculate the indices of insulin sensitivity and of glucose effectiveness using Bergman's minimal model during a simple intravenous glucose tolerance test performed without tolbutamide injection. Two intravenous glucose tolerance tests (separated by 1 week) were performed in 7 lean normal subjects and a single test was performed in 9 severely obese non-diabetic subjects. Intra-subject reproducibility of insulin sensitivity was not significantly different when 26 or 12 time-points were analyzed (CV = 16.8 +/- 3.4 versus 18.9 +/- 3.8% respectively). Compared with the insulin sensitivity of the lean subjects, that of obese subjects was significantly (P < 0.001) and similarly reduced when using 12 (2.14 +/- 0.34 versus 7.97 +/- 1.29 10(-4)min-1/mU.1-1) rather than 26 determinations (2.13 +/- 0.42 versus 6.95 +/- 1.12 10(-4) min-1/mU.1-1) respectively. Glucose effectiveness was less reproducible than insulin sensitivity and was slightly diminished by the reduction of blood samples (relative error: -9.7 +/- 4.4%; P < 0.05). Finally, glucose effectiveness tended to be slightly lower in the morbidly obese subjects than in the lean controls with both modes of calculation. In conclusion, in non-diabetic subjects, the insulin sensitivity index can be accurately measured during a simple intravenous glucose tolerance test, without tolbutamide injection and with only 12 blood samples. The possibility of performing a simplified test should contribute to increase the use of the minimal model method for estimating insulin sensitivity in clinical practice. [less ▲]

Selective lifetime measurements by time-resolved laser-induced fluorescence spectroscopy for 5 levels belonging to the 4f(3)5d configuration of doubly ionized neodymium provide a first and useful experimental test of the relativistic Hartree-Fock calculations in this ion of astrophysical interest. As a consequence, the accuracy of the transition probabilities deduced in the present work is well assessed. These new data are expected to help astrophysicists in the future to refine the analysis of the composition of chemically peculiar stars which frequently show large overabundances of lanthanides when compared to the solar system standards.

This paper presents the results of an experimental study carried out to examine liquid hold-up in 100 mm diameter catalytic structured packing Katapak-SP. Two versions of the packing have been investigated. Both global and local measurements were carried out on the very same packings, using water at ambient conditions as working liquid. To this scope, traditional methods like draining techniques were used to obtain global hold-up values. A non-intrusive high energy X-ray tomography was used for gathering information on local scale and study axial distribution of the liquid hold-up over the packed column, inside and outside the catalyst containing baskets. The total liquid hold-up of the catalytic packed bed was evaluated by averaging hold-up values obtained at different cross sections over the corresponding volume. Very good agreement was found between global values estimated with the different techniques. The experimental results are useful for supporting theoretical developments in hydrodynamic and mass transfer modeling. [less ▲]

This work reports the results of experimental study concerning convective drying of cement mortar and the influence of water-to cement ratios (W/C) used for the preparation of mortar, on moisture changes. The first experimental campaign was a convective dryer; in the purpose to obtain the drying curves of mortar and the influence of water to cement ratios (W/C) on drying kinetics. A second experimental campaign aims to characterize from textural and hydric point of view, the materials, by mean of DVS (dynamic vapor sorption) In order to obtain sorption cycles and identify the moisture diffusivity coefficient of mortar. The pore size distribution is obtained from sorption cycles and completed by MIP. The contribution of each components of the microstructure to the diffusion is studied. Finally X-ray microtomography is used to measuring the moisture content in the internal structure of mortars during drying. [less ▲]
