Tuareg Travelling to Europe: Particularities and Continuities

Considering the Nigerien Tuareg migrations to Europe two main features can be noticed: fi rst, a pattern of return migration and, second, the inclusion of European friends in the networks used in travelling to Europe. The fi rst feature agrees with certain nomadic ideas of travel like gaining new knowledge to adapt at home. Therefore, all the other traits of Tuareg experiences in travelling to ...

Travelling far but staying close to home.

A n overwhelming majority of the global burden of morbidity and mortality caused by sexually transmitted infections (STI) and HIV is borne by the world’s poorest countries (fig 1). In a world increasingly ‘‘shrunk’’ by modern communications, what are the common issues preoccupying the international community of researchers in our field? In planning this themed issue, published on World AIDS Day...

Travelling to exotic places with ultracold atoms

We review and speculate on two recent developments of quantum optics and ultracold atoms. First, we discuss a possible realization of “phonon” physics, or as we call it refracton physics with optical lattices. To this aim we combine the physics of cold atoms with cavity QED, and investigate superfluid – Mott insulator quantum phase transition. The systems can exhibit cavity mode modifications d...

Travelling to High Altitudes Could be Thrombogenetic!

People ascending to high altitude regions are at risk for a variety of health problems, commonly including acute mountain sickness (AMS), high-altitude cerebral oedema (HACE) and high-altitude pulmonary oedema (HAPE) etc. Increasing travel to mountainous terrains has brought light to several other medical problems as well. It has been well recognized that a hypercoagulable state exists when a p...

A Variational Approach to Travelling Waves

A Travelling Salesman Approach to Protein Conformation

A simple method for finding conformational substates of proteins is presented and realized through computer simulations. It is based on a procedure in which the amino acids in a protein take the places of the cities in the three-dimensional travelling salesman prob lem. Optimization by simulated annealing was employed in the computer simulations to obtain conformational substates originating fr...
