To treat respiratory problems, predict the course of vascular disease or detect malaria in the blood, doctors are turning to the physicists of the flow of fluids.

Thus begins a wonderful article published in the Journal du CNRS.

Julien Bourdet explains that to understand the overall functioning of the human body, it must not only be able to represent the organs that compose it, but also the fluids that run through the.

That is why specialists in fluid mechanics attempt to model as closely as possible how gases and liquids travel the bloodstream and airways.

With the key, the ability to improve medical diagnostics and tailor treatments.

The first example given is that of screening for risk of atherosclerosis, the disease characterized by the deposition of a plate, consisting essentially of fat, in the inner wall of an artery.

It gradually reduces the diameter of some vessels and may eventually prevent the flow of blood.

The work of physicists has shown that its development is largely due to the mechanical stresses exerted on artery walls.

Downstream of a bifurcation of the blood network, the flow slows down, “explains Gwennou Coupier, the Interdisciplinary Physics Laboratory, Saint-Martin- d’Hères.

Result: certain cells, white blood cells in particular, which are not carried away by the stream there, reach into the artery wall, thereby promoting the growth of a plate, the origin of the disease.

Such information allows physicians to monitor priority – MRI – certain areas in patients risk.

The acute respiratory distress syndrome is another disease where fluid mechanics could be of great help.

This inflammation of the lungs causes the death of over 10,000 people each year in France.

Unfortunately, the surfactant injected to help the lungs to swell more easily – very successfully used in premature babies – does not give good results in adults.

The fundamental difference between the lungs of an infant and those of an adult, it’s their size, “says Marcel Filoche, the Physics Laboratory of Condensed Matter Palaiseau.

The model he developed with his team shows the volume injected to the patient to ensure treatment success.

It also points to other critical parameters taken into account as the injection speed, the density of the liquid, its viscosity, but also the patient’s position in space, gravity aiding the surfactant diffuse into the lungs as a function of angle different pulmonary branch.

Obviously, fluid mechanics has not finished to advance medicine.

Today I want to talk about G & eacute; raldine Ayache, teacher sp & eacute; cialis & eacute; e who makes a work rem dé great mediation with Julien, but not with him : in fact, G & eacute; raldine intervenes aupr & egrave ; s more children autistic, mentally disabled, various dys and dé also an autistic child pr & eacute; feeling great difficulty & eacute; s & eacute; so small with a future promised wheelchair accessibility sp & eacute; cialis & eacute; but now a bright dé student & eacute; g & panoui acirc ; it all she undertook to do progresserLe here in this article, advertising & eacute; in 2011.

Today, Julien is halftime with G & eacute; raldine, which makes it follow by adapting the course of CNED within its MUSICAM Association and worked with him in diff & eacute; ent areas : communication, dé Noise Awareness, neat & eacute,, independence, socialization, behavior, etc.

How did you come from your m & eacute; tier of origin to support & eacute; & eacute ducatif to handicap children s ? My m & eacute; tier of origin is to teach the violin, the dé musical veil and musical training in diff & eacute; annuities associative structures, municipal some radiation r & eacute; Regional, aupr & egrave ; s of adults and children from the & acirc ; age 3 years and special needs.

I never s & eacute; lectionn & eacute; my & eacute; l & egrave ; ve compared their level or ability & eacute; s Particular & egrave ; res.

Just to want to make music and / or violin.

I quickly finding & eacute; learning the music and especially the violin helped some of my & eacute; l & egrave ; ves progress in motor skills & eacute;, Coordination, reading, concentration, etc.

Passionate & eacute; e to transmit I cr & eacute; & eacute; Then, there are more than 30 years, an approach to down & eacute violin e on dé composition spots and structuring of work to make all available violin, which uses a lot: motor skills & eacute;, Coordination, reading, breathing.

I always purposively & eacute; thus : Help me help you.

For personal reasons ( after accidents ) I dé velopp & eacute; for my m & ecirc ; me techniques and proc & eacute; d & eacute; s reconstruction gesture with g & eacute; n & eacute; realization and cr & eacute; ing a m & eacute; method of dé cognitive development and motor.

The r & eacute; results are spectacular : for example one of my & eacute; l & egrave ; ve left had its price Paris, remport & eacute; international competitions and a soloist with an orchestra in China, no one glimpse ccedil & ; u he dé was left.

In fact, I have always worked & eacute; aupr & egrave ; s diff & eacute people ; ent.

I continued p & eacute research; Pedagogic like cr & eacute; ing a m & eacute; method of learning the violin of dé veil from 3 years late 2 & deg ; cycle and a m & eacute; method of learning reading and numeracy for children from 3 years.

Gradually, before the success & egrave ; s my job aupr & egrave ; s several dé l & egrave ; ves including my son, I did, on the recommendation of center dé tracking autism Grenoble and r & eacute; bucket health & eacute; ANA & iuml ; S, the & quot; r & eacute; & eacute; education & quot; aupr & egrave ; s of adults and children with or without special needs dé intellectual ciency.

I dé also performed & eacute; aupr & egrave training ; s various organizations, aupr & egrave ; s professional orthoptist, speech therapist and I auto form & eacute; e.

I suggest using all learning in all areas : life, school learning acad & eacute; nomic : graphics dé writing, pr & eacute; reading, reading, math, communication, m & eacute; morisation, attention dé development of autonomy, joint production of sounds, breath, voice work, motor skills & eacute ;, breathing, dé noise Awareness, neat & eacute ;, etc.

I can occasionally intervene anywhere & ugrave ; & raquo ;, I work mostly in an association, which allows for access & egrave ; s an important mat & eacute; p riel & eacute; Pedagogic.

I try dé develop to the maximum the comp & eacute; skills of each, according to his expectations.

What is your mani & egrave ; re teaching ? On what p & eacute; pedagogy / media / m & eacute; of learning methods you bases you I have a range of approaches my disposal including : ABA, TEACCH, Pecs, Makaton, LSF, Braille, Borel Maisonny carriers and matt & eacute; riels many and varied & eacute; s and books, computer, video & eacute; o, tablet, musical instruments.

I adapt and cr & eacute; e media over the individual needs.

I have my own approach and according to the time I use this or that.

Are you recognized by public Institutions & eacute; ? L & egrave ; ve come from word of mouth or recommended & eacute; s by CADIPA or r & eacute; bucket Ana & iuml ; s or professional health & eacute; I met & eacute; the d & eacute; could & eacute; Martin Pinville in spring 2013, which I requested & eacute; to continue my work and train people.

The & eacute; l & egrave ; ves who register halftime music dé school can b & eacute; n & eacute; acquirable courses CNED registration r & eacute; Rules & eacute; e.

What is your price possible means of payment rates vary according to the formulas chosen : individual lessons, and group and en dé frequency.

Can you dé Music’Am write your Association ?

Is a 1901 law association that offers training relevant to the dé artistic development and intellectual, with such music education, acad é teachings ; nomic various learning, courses, courses for all, adults, children.
