Mineral filters in sunscreen products--comparison of the efficacy of zinc oxide and titanium dioxide by in vitro method

Autor: C, Couteau, S, Alami, M, Guitton, E, Paparis, L J M, Coiffard

Publikováno v: Die Pharmazie. 63(1)

European legislation currently authorizes 26 sun filters among which, there is only one mineral filter: titanium dioxide. In the United States, two mineral filters are authorized: titanium dioxide in a maximum dose of 25% and zinc oxide. Zinc oxide i

APPLICATION DE LA MODÉLISATION DE L'APPAREIL PHONATOIRE À LA CARACTÉRISATION DE LA PAROLE HYPERBARE

Autor: J. Crestel, M. Guitton

Publikováno v: Le Journal de Physique Colloques. 51:C2-479

Cet article presente la methodologie et les resultats d'une etude theorique de l'incidence sur la phonation des melanges respiratoires synthetiques utilises actuellement dans le contexte de la plongee profonde. L'etude est fondee sur une hypothese de

From the Petri net model to real time control: bases of a development package

Autor: J. Crestel, M. Guitton

Publikováno v: ETFA '94. 1994 IEEE Symposium on Emerging Technologies and Factory Automation. (SEIKEN) Symposium) -Novel Disciplines for the Next Century- Proceedings.

Any discrete system with a behavior which lends itself to a graphical representation can be a candidate for a Petri net modelization. In this way the Petri net model can be adopted more and more in process control, especially within the framework of

A Doppler frequency estimate using the instantaneous frequency

Autor: M. Guitton, B. Emile, D. Menard, J. Crestel

Publikováno v: Proceedings of 13th International Conference on Digital Signal Processing.

In the preamble it is shown that, under a quasi-stationarity assumption of the multi-component Doppler signal. The assimilation of the Doppler frequency to the mean instantaneous frequency is consistent. Basically, this frequency can be estimated fro

Fine alterations of distortion-product otoacoustic emissions after moderate acoustic overexposure in guinea pigs

Autor: M, Kossowski, T, Mom, M, Guitton, J L, Poncet, P, Bonfils, P, Avan

Publikováno v: Audiology : official organ of the International Society of Audiology. 40(3)

Guinea pigs were exposed to a pure tone at 6 kHz and 80 dB SPL for 30 minutes in order to induce mild reversible auditory fatigue over the 4 hours following exposure. Cochlear monitoring aimed to compare the shifts in round-window compound action pot

Caractérisation de voyelles en mélanges respiratoires synthétiques sous fortes pressions

Autor: J. Crestel, Laure Charonnat, M. Guitton

Publikováno v: Journal de Physique IV Proceedings
Journal de Physique IV Proceedings, EDP Sciences, 1994, 04 (C5), pp.C5-473-C5-476. ⟨10.1051/jp4:1994599⟩

Les plongeurs qui travaillent aux grandes profondeurs inhalent des mélanges respiratoires synthétiques. L'action conjuguée de la profondeur et des caractéristiques physiques des mélanges entraînent une perte d'intelligibilité quasi-totale de l
