Kushti is a traditional form of South Asian wrestling popular in India, also known as Pehlwani. Wrestlers usually meet in an Akhara, a "wrestling ground" which is a place of practice, with facilities for boarding, lodging and training.They serve both as training schools and an arena for wrestlers to compete against each other. Akhara is not limited only to physical activities, but also involves religious practices, particularly the worship of the god Hanuman.

The province of Mendoza is part of all Argentine provinces that are vertically crossed by the Cordillera de Los Andes. The Principal Cordillera is the result of an early folding, with an average height of about 6500 meters. It has two distinct sectors: in the north and to the provincial Diamond Rio is characterized by a high narrow strip, which finds its highest expression in the Cerro Aconcagua 6962 m. In the southern provinces, from Diamond Rio to the South forms a wider and less high orographic belt.

Tara Oceans Expeditions - May 2011. Tara with deployed plancton nets. On "station", the boat is drifting without engine or sails. Tara Oceans, a unique expedition: Tara Oceans is the very first attempt to make a global study of marine plankton, a form of sea life that includes organisms as small as viruses and bacterias, and as big as medusas. Our goal is to better understand planktonic ecosystems by exploring the countless species, learning about interactions among them and with their environment. Marine plankton is the only ecosystem that is almost continuous over the surface of the Earth. Studying plankton is like taking the pulse of our planet. Recently, scientists have discovered the great importance of plankton for the climate: populations of plankton are affected very rapidly by variations in climate. But in turn they can influence the climate by modifying the absorption of carbon. In a context of rapid physico-chemical changes, for example the acidification observed today in the world's oceans, it is urgent to understand and predict the evolution of these particular ecosystems. Finally, plankton is an astonishing way of going back in time ? a prime source of fossils. Over the eons, plankton has created several hundred meters of sediment on the ocean floors. This allows us to go back in time, to the first oceans on Earth, and better understand the history of our biosphere. More than 12 fields of research are involved in the project, which will bring together an international team of oceanographers, ecologists, biologists, geneticists, and physicists from prestigious laboratories headed by Eric Karsenti of the European Molecular Biology Laboratory.
