The research group “Physics of the Atmosphere” (CEAMA-University of Granada, Spain) has created a new web service which provides daily information about the Ultra Violet Index (UVI). It is advisable to revise it for a proper protection against eyes and skin’s sunburn.
According to the data provided by the World Health Organization (WHO), overexposure to ultravioleta radiation causes more than two million new cases a year of processes, more or less serious, of cataracts in eyes.
Knowing the Ultra Violet Index (UVI) allows to prevent the harmful effects of sun exposure. The research group “Physics of the Atmosphere” (CEAMA-University of Granada, Spain-Andalusian Council) has created a new web service which provides daily information as part of a research work directed to the characterization of the interaction of atmospheric aerosol and clouds with solar radiation.
In http://atmosfera.ugr.es/investigacion/uvi/uvi%20(es).htm, the “Internet users” can get information about the UVI in Granada (Spain) on a scale from 1 to 11. Index 1 or 2 means that no sun protection is necessary; between 3 and 7 means that it is advisable to take measures at the central hours of the day; and 8 to 11 means that it is recommendable to maximize protection measures (according to the typical numbers followed by sun protection, appropriate clothes, sun glasses, etc.). These last two cases refer to more or less prolongad exposure to sunbeams, as the WHO and doctors advise to do.We can not see it
That is why they recommend to consult the UVI every day: “it is about adopting the habit of getting information, as we do in order to know the weather and temperature”. In the near future, it will be habitual in cities and, above all, in beaches, to offer information about the Ultra Violet Index. For the moment, we can already know the UVI in Granada.
-We must protect all through the year and in all seasons, contrary to the belief that if there are clouds ultra violet radiation can not reach us or that we will not get burnt when it is not hot.
-Under the sombrillas sunshades, in the beach, we ahve no protection against ultravioleta radiation. Radiation comes not just from above, but also from the sides, as the sea and the atmosphere act as a mirror and Spreads it.
-Snow also reflects UVI rays spreading them in all directions.
-Bronzed persons have no better protection against sun, as their skin shows (beyond an esthetically pleasant colour) a high degree of accumulated sunburn. It is advisable to be prudent.

Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz (Germany) together with scientists from Dresden, Leipzig, Sofia (Bulgaria) and Madrid (Spain) have now developed and characterized a novel, metal-organic material which displays electrical properties mimicking those of highly crystalline silicon. The material which can easily be fabricated at room temperature could serve as a replacement for expensive conventional inorganic materials used in optoelectronics.
Silicon, a so called semiconductor, is currently widely employed for the development of components such as solar cells, LEDs or computer chips. High purity...

When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
