I am a feMALE studying at Purdue University for Mechanical Drafting and Computer Animation... I think that we all need to get real and stop worrying about whether someone calls use draftsMEN or whatever!!! MAN has been used to refer to both men and woMEN for centuries, and it is definitely "too much time on our hands" that has caused us to worry about such minor things. I am a woMAN and proud of it. I am not weak because I am feMALE, but I don't have to have the English language changed in order to prove that!!!! Get on with something that is important in life and get over this feminist attitude. People like you ruin being a woMAN for people who are proud to be one! ToniReturn to Top

I don't know how much trouble it would be, but you may be able to set up some "tests", and measure the parameters you need. If this isn't beyond reason, you could curve fit some type of polynomial expression to your data. If this is totally impractical (it probably is), you may be able to find some research work (or something previously published) in this area. Good luck.

Hello ! Does there exist any simple model that estimates vertical/diapycnal mixing coefficients K and/or dissipation rate of turbulent kinetic energy of a stratified sheared (incompressible) flow downstream of an obstacle (cf sketch below) ? (model which could be based on spectral shape of the obstacle and/or vertical velocity shear, stratification, Froude Number,...) Thanks, Bruno.

Hey folks........ Do you girs really care that much?????? Most of the female engineers and designers I have worked with over the years couldn't care less what their job title is, even if it is incorrect genderwise.... The important thing is they were all good engineers....and they worried more about their work.....( oh..and their salaries....), just liek the male engineers..... They even join in sometimes with everyone else..... Hey...actually they were JUST THE SAME!!!!!! In fact the only real difference I ever noticed is that they use a different washroom......... This may sound i bit over simplified.....but some of us are maybe oversimple..... Should we forget about trying to pigeonhole everybody genderwise....and get down to the interesting stuff. What do you say ? (Boys AND girls that is....hehehe) P.s. Most of my colleagues just call me by my name.....and I can live with that!Return to Top

L'influence de la bathymetrie et de la stratification sur l'evolution d'un courant et de la surface libre est analysee. Cette etude se concretise par une simulation realiste de la section du courant Nord face a la baie de Monaco. Le transport du sable et de la vase est considere sous l'action d'un courant et de la houle. Puis, une etude sur le transport des particules organique permet d'evaluer la production primaire dans la colonne d'eau. ============================================================= ENGLISH ============================================================= Tuesday 19 november 1996, 10h30, conference room of IRIGM University of Grenoble (FRANCE) -------------- Tridi-flow and transport in coastal zone : numerical modeling -------------- by Cristele BERTHET for the title of : Docteur en mecanique geophysique PhD. carried out at the LEGI (Laboratoire d'Ecoulement Geophysique et Industriels) University of Grenoble (FRANCE) Abstract : We studied a characteristic flow in a deep coastal zone and the transport of sediment using a three-dimensional numerical model. The influence of bathymetry and stratification on flow and water level was analysed. This study is applied in the simulation of a part of the "North current" of the coast of Monaco. The transfer of sand and clay was studied under the influence of flow and waves.

And everyone should just get over it and go on. Stop complaining about whether they are called MEN or whatever... It has gotten totally out of hand. Although I do want to say that yesterday was the first time that I have ever responded to a newsgroup (I have been reading them, but I haven't been putting in my input) and when I responded I responded to the wrong person, I was trying to get my point across to the woman who started all of this JUNK, not to Katarina. So my apologies about that mistake. I was just trying to get the portion of Katarina letter that stated the original concern and I didn't get all of her personal message erased like was intended.

The Second Biennial European Coating Symposium Euromech Symposium 367 Fluid Mechanics of Coating Processes 22nd - 25th July 1997, Université Louis Pasteur, Strasbourg, FRANCE. Background Interest in Coating Process Fundamentals and their Applications has risen sharply in recent years. Indeed fluid film coating is now an established as an interdisciplinary research areas incorporating analytical, computational and experimental methods. The organisers of the Second European Coating Symposium aim to continue the spirit of the ECS '95 by: * attracting a healthy balance of academics and industrialists; * providing a suitable forum for the presentation and discussion of recent work and the informal exchange of ideas; * including a varied programme of keynote presentations, papers, sponsored poster session, social events and a conference dinner. The Second European Coating Symposium will be held at the Université Louis Pasteur de Strasbourg (France), in July 1997.

It's been Drafter and Designer since when I rode my dinosaur to work before I got my '47 Plymouth. A designer is a drafter with more time on the board and more catalogs on the shelf. Or these days, more time on the mouse and more vendor CAD files on the hard drive. And I'll tell ya what: There comes a point in life when the last thing you worry about is silly things like job titles . . or whether the designer/drafter wears a skirt. (Yes, Viginia . . women USED to wear things called skirts . . before they were "liberated" and became "regular guys" . . ). Ta-ta. cbk
