,On the nose! Fragrances and natural essences,in Pineda de Vila-seca until August 31th

La Pineda of Vila-seca. Costa Dorada. The Obra Social de la Caixa carries in the Pineda of Vila-seca, until August 31th, the exhibition "On the nose! Natural essences and fragrances".This is the first time you see this show through a new resource called ExpoCaixa. May be seen at the Park of the Pinar del Perruquet in la Pineda of Vila-seca, on Monday through Sunday and holidays from 11 to 14 h at 18 to 23 h. The exhibition allows natural smelling fragrances such as thyme, jasmine, sandalwood and lemon, but also smell the filthy liquid secretion of the civet (a small African animal), which, according to legend, the king Salomó is scented . "For nose" is an approach to the world of smells that offers visitors the chance to develop, through the 26 aromas exposed, the most overlooked of the five senses: smell. In this case, the public can learn about different herbs and spices, flowers and fruits and animals, the scientific basis of smelling, the historical and cultural aspects of the relationship of man with the world of smells and the memories they evoke . Why are there odors? To be able to give an olfactory sense is necessary, first, show that the element particle, that is, to release molecules. As the olfactación occurs by contact, we can not smell if this phenomenon occurs, this is the case of minerals in general, metal, glass and water, no smell (water, if it smells, because it contains something else, eg chlorine). Secondly, it is necessary that these particles are transported by a physical medium such as air or water to get to our olfactory organ. Finally, it is also necessary that the cells of the body are sensitive to the substance that smells and the number of particles is sufficient, this is above the threshold of perception. Failure to fulfill these assumptions smelling or no odor. In addition, particles can not be smelling any kind, but must be formed from carbon, hydrogen, oxygen, nitrogen and sulfur. These particles are slightly soluble in water molecules to pass through the mucus and can be soluble in lipids to connect with the olfactory receptors. Because the essences are extracted from certain plants, the scent given off is not exactly like what we know and sometimes it is very different. For this reason, the technical team of the exhibition has had to do a research with the aim of achieving a solution that was neither too concentrated nor too dilute to correspond with the real smell of the substances listed in the sample. Origin and evolution of odors The development of the senses is a cornerstone of the evolution of animals, enabling them to adapt to the environment and respond to changes. The senses receive information from the environment in the form of physical and chemical stimuli, and transmitted to the brain. The structure and location of the meanings are very diverse. A curious example may be that of the butterflies: they have taste receptors on their legs to identify the flowers of which suck the nectar. The smell, very sensitive, is located on the antennae. In some species, the olfactory sensitivity is remarkable. Among the highlights of invertebrate insects. Among vertebrates, the mammals, particularly rodents, felines and canids. Human beings, though not prominent among the animals for their olfactory sense, such as mammals have a high ability to smell. In addition, it uses the highest perception of animals: pigs to find truffles, dogs to hunt, you find people, locate drugs, etc.. Another of the qualities of smell is the persistence of the external stimulus. An animal can not see, hear or touch anything that does not have in front of it. However, by smell, it can capture the presence of something, even after a few days. It is the result of the persistence of the odorous substances, which are still emitting particles identifiable long. Thus a dog can keep track of a fox or a rabbit, a butterfly male partner is a kilometer away, without even having seen or heard, or a feline strengthens its presence to be captured by any competitor. ExpoCaixa ExpoCaixa approaching target protein and sensitize the general public, putting everyone at a series of exhibitions of an informative nature on social, environmental, historical and scientific way that is understandable and games, with the aim to stimulate awareness and create meeting. "For noses!" runs using the territory as a multidisciplinary platform trailer. In this way, the exhibition, which is inside a container enabled, you can easily go the villages, which reaches a very high number of venues in the shortest possible time. This exhibit uses an innovative system of automated container to conserve and preserve the complex mixture of gases, fumes and dust which has been developed each fragrance. Moreover, the wide space that offers the trailer once open, allows different modules closed methacrylates exhibitors and create an atmosphere of silence and darkness so that odors are the only players of the moment.
