|Title:||Generation of isolated vortices in a rotating fluid by means of an electromagnetic method|
|Abstract:||Obesity and nonalcoholic steatohepatitis are increasing in westernized countries, regardless of their geographic location. In Latin America, most countries, including Mexico, have a heterogeneous admixture genome with Amerindian, European and African ancestries. However, certain high allelic frequencies of several nutrientrelated polymorphisms may have been achieved by past gene-nutrient interactions. Such interactions may have promoted the positive selection of variants adapted to regional food sources. At present, the unbalanced diet composition of the Mexicans has led the country to a 70% prevalence rate of overweightness and obesity due to substantial changes in food habits, among other factors. International guidelines and intervention strategies may not be adequate for all populations worldwide because they do not consider disparities in genetic and environmental factors, and thus there is a need for differential prevention and management strategies. Here, we provide the rationale for an intervention strategy for the prevention and management of obesity-related diseases such as nonalcoholic steatohepatitis based on a regionalized genome-based diet. The components required to design such a diet should focus on the specific ancestry of each population around the world and the convenience of consuming traditional ethnic food. " The Author(s) 2015.

Pinilla, M.A.",,"2013",,"We present a method for generating isolated monopolar vortices in rotating tank experiments. The technique is based on the electromagnetic forcing commonly used in nonrotating systems, which consists of setting a vertical magnetic field - parallel to the rotation axis - and a horizontal density current in an electrolytic fluid layer. The magnetic field is provided by a permanent magnet placed underneath the central point of the fluid container, while a radial density current is established between a central electrode and a number of opposite-sign electrodes at the periphery. The resulting azimuthal Lorentz force creates a monopolar vortex. It is shown that the generated vortices are axisymmetric and isolated, that is, their total circulation is zero. Cyclonic or anticyclonic vortices can be generated by choosing the appropriate polarity of the electrodes or the orientation of the magnet. The strength of the vortices is regulated by the magnitude of the density current and by the forcing time. This method allows the systematic study of the unstable evolution of isolated vortices, which is characterized by the formation of multipolar vortices. " 2013 Springer-Verlag Berlin Heidelberg.
