Link found between golden ratio and atomic symmetry

Researchers
in Germany and the UK have discovered symmetry hidden in solid state
matter at very small scales. The findings, published in the journal Science,
indicate that symmetry involves the golden ratio famous from art and
architecture. The research was supported in part by the NMI3
('Integrated infrastructure initiative for neutron scattering and muon
spectroscopy') project, which was funded under the 'Coordination of
research activities' Thematic area of the EU's Sixth Framework
Programme (FP6) to the tune of EUR 21 million.

dear Friend

I am comparing italian universities with Russian ones with US and with Cuban ones. Then I need some figures.

I have been able for example to find that there are about 50% of students-workers in Russia, what about US?
I mean full time workers, not just part time.

But I need to know more about these questions:-
1) how did the number of students in the last 10 years vary?  Increased?
2) how many students are doing economics or management - related subjects?
3) how many students exit the university system before graduation,
failing to complete the cycle?
4) how many students complete the cycle in retard?

I am going to Modena on Monday to talk to my collegues in the Millechili lab (MilleChili means 1000Kg in italian)

Dear Friend/Collegue

  please find enclosed a letter to the Editor of the journal Proc. IMechE Part F: J. Rail and Rapid Transit, where I challenge Dr. Grassie to explain why of his radical change of opinion, which appears not supported by data, in the new version of the REVIEW "Rail corrugation: characteristics, causes, and treatments" published in May-June 2009, much different from the same review of 1993.

If you are upset about promotion system, look at what two italian friends proved recently, which was immediately popular before the paper publication, also because they proved random promotion is more efficient!

Dear Collegue

We are organising in July 7-9, 2010 an Euromech workshop on Multiscale
effects in Fatigue, at the Ecole Polytechnique, near Paris in France.
Outcomes and topics are detailed on the following web site:

http://www.lms.polytechnique.fr/Euromech

We would be honoured if you could contribute to this workshop to present
some of your recent research results.  The workshop is thought as a small
meeting in order to promote active discussion on the hot topics in this
field.

with kindest regards
Andrei Constantinescu & Michele Ciavarella

A recent paper on JMPS has seriously questioned the foundation of the SGP theory of Fleck and Hutchinson.  The matter is not simple, but is it a good bench test for imechanica to discuss?

For those interested in a classical subject like contact mechanics, here are a couple of recent papers published in August.  One is an extension of the Greenwood Williamson theory of rough contact, and the other is a linear perturbation solution of the classical Carter rolling contact problem for a rolling cylinder, when the surface is corrugated and hence there are oscillations in both normal and tangential loads.

EU also behindin terms of overall citation impact.

After some conversation with Roozbeh which are "irritatingly useful" :) I found that this site has done already all the calculations we need http://www.scimagojr.com/  except the list of highlycited papers which remains for me the most interesting aspect and which we seem to need to do manually as we did yesterday with IJSS and JMPS at Most cited papers and H-factor of some mechanics journals -- IJSS

Some results are attached as a big PDF file.

IMPORTANT UPDATE JULY 18

The full list of journals ranked by H index

It is possible to rank journals equally as authors, using e.g. the Harzing Publish or Perish sofware based on Google Scholar. I did the excercise for IJSS. It turns out the H-index is 78 (slightly higher than even the best authors in solid mechanics, but not stellar).  In the most highlycited papers, we find good names, but not stellar papers.

The results may be affected by the limitations of the software.

UPDATE:  IT APPEARS THAT HARZING HAS TWO PAPERS ON THIS IDEA, SEE ATTACHED.

Schwarzenegger Says He Would Accept Obama Appointment

Melanie Trottman reports on the presidential race.

Guests on the Sunday newsmaker shows, including California Gov. Arnold Schwarzenegger and John McCain adviser Carly Fiorina, spotlighted energy and the economy and paid tribute to former White House press secretary Tony Snow.

These type of projects are interesting, when a mechanics-based one?
