  • Molecular Structure

    There is something simple aparentementemas than water? Despite its apparent simplicity esteliquido that we know so well is complex and understand todaviano well.The water is equipped with a few exceptional chemical propiedadesfisico that constitute its specificity. Comopone manifesto estearticulo, the estructuramicroscopica of liquid water, which is inthe base of estaspropiedades, esun theme research may contribute algunasnovedades. Water is one of the four ‘elements’ which the Greek philosopher Aristotle had defined as constituent of the universe (the others are the air, Earth and fire). Even today it is not that we better understand. Given our familiarity with the water, the fact no longer surprising. Oceans, lakes, rivers, rainfall; abundant in nearly all the regions of the Earth, the water determines largely the landscapes and climates. Very often is synonymous with life: water is an essential component of the structure and metabolism of all living beings.

    Certainly, the primary role of the water should not be attributed to random but that derives from its exceptional physical and chemical properties. An example of biologically important property of water is their hydrophobic effect, i.e. the fact that CH hydrocarbon groups tend to be repelled by water molecules. This effect is responsible, in part at least, of the complex spatial structures that present proteins, DNA and the bi-layers imminuta of cell membranes. In the absence of water, all of these structures would be unstable. It should be even, without too much risk of error, that this effect could play a decisive role in the emergence of life on Earth to say.

    But the hydrophobic effect is not the only interesting property of water. In what follows we will find others. Why is water a chemical so privileged? The answer, of course, found in the molecule and their interactions with the environment. The water molecules are relatively well known, but interactions that are set out in a group of water molecules as they are less.

  • Thalassotherapy

    After the unsanitary and dark years of the middle ages in the 16th century, we see the first light of the revival of the culture of water with the writings of the physician and anatomist Ambrosie stop on anti-infectious properties of sea water, sea bathing prescribing to their patients for its astringent properties, recalentantes and deshidratantes. But it was in England where became the rebirth of hydrotherapy marina with the publication of the book of Doctor Charles Rusell in latin in 1753 glandular tabe usu in morbis glandularum dissertatio marinae aquac sine, which was translated into English as The use of sea water in the diseases for glands. This book had a great impact on their country and gave rise to the birth of the first establishments of baths, specifically in Brighton was the first of them. Russell says the healing benefits of the sea water: need to drink sea water, bathing and eating all the things that come from this water, where all the virtues are concentrated. In 1790 the doctor Latham creates first military marine hospital. At the end of the 18th century there were no less than 60 establishments in bathrooms in England. They were small buildings, directly on the beach.

    Somewhat rudimentary with some bathtubs, changing cabins, swimwear distribution cabins and cabin for the doctor. There were also some nurses who were those who helped the sick to take bath. At the same time in France, on the coast of Aquitaine, we begin to find cities spas such as San Juan de Luz, Biarritz and Bayonne. But it was not until the 19th century when see in this country the birth of Thalasso-therapy as a discipline and to the creation of the first spa hotel. Original author and source of the article
