Structuration of Magnesium Surface by Acoustic Cavitation

4b and 4c, which show also a small shift of the carboxylic stretching band to lower wave numbers, in agreement with an increase of the C-O bond length can be attributed to

Du coté des fréquences radar, l’augmentation de taille des antennes (en 1/F) requise par l’abaissement de la fréquence et une certaine répugnance à travailler en

perature which decrease the atomic disordered and hence the residual resistivity, as well as the resistivity temperature minimum due to localization effects. An important feature is

L'utilisation de tels systèmes en environnement naturel pose, cependant, un certain nombre de problèmes aux quels nous nous efforcerons de trouver des solutions dans la conception

- The experimental work consisted of measuring the amplitude of the fundamental component of the wave and its first three harmonics for different input powers on the transducer

In the dilute alloys studied exchange interactions are small perturbations on the crystal field and the exchange can be adequately treated in the molecular

The vibration frequency was high enough (KHz) to eliminate the transitory internal friction. A peak of internal friction accompanied by an anomaly of the elastic modulus

Thus, while the experimental and numerical profiles of the velocity vertical component are in pretty good agreement, the numerical prediction is still in excess by a three-fold
