    FRENCH SOLAR POWER PLANT
    January 25, 1977 - Odeillo in the Pyranees of southwestern France

    France inaugurated its first operational solar generating plant at Odeillo in the Pyranees of southwestern France. Its output of 64 kilowatts (sufficient to power about 1,000 60-watt light bulbs), was connected to the national electricity grid to demonstrate operational solar power. The plant was part of the huge solar furnace project run by the National Center for Scientific Research. The site was built for high-temperature research using an eight-story parabolic mirror to refocus sunlight from an extensive field of mirrors on a hillside in front of it, with 63 moveable mirror arrays designed to follow the motion of the sun. The electricity was generated by a turbo-alternator driven by steam from a boiler at the focus of the reflected sunlight. Alignment of the mirrors began in May 1969.

    FLUORIDATION
    January 25, 1945 - Grand Rapids, Mich. U.S.A.

    Grand Rapids, Mich., became the first U.S. city to begin fluoridating the drinking water. With the intention of reducing tooth decay, one part per million of fluoride was added to the water supply. Fluorine is the 13th most abundant element on earth, found in nature in its ionic form - fluoride - in combination with other elements, such as calcium, magnesium, phosphates etc. This fluoride is present in small yet varying amounts in almost all soils, water supplies, plants, and animals and, therefore, is a normal constituent of all diets. In mammals, the highest concentrations are found in the bones and teeth. Decades after the conclusion of the Grand Rapids fluoridation study, fluoride continues to be dental science's main weapon in the battle against tooth decay.

Website preview thumbnail for : The Interior Design Of A House Matters
The article is devoted to space arrangement in a house based on the personal and psychological approaches which feature comfort and harmony of the interior.
Article Content :It has been proven that the interior of the place we live in impacts upon our inner state and mood. Luckily, the time when the home interior was grounded on practicability and utility is a thing of the past, and here come a personal and a psychological approaches to the forefront. An apartment or a private house is gradually turning from the space we reside in into the place that reflects our inner world. The style is based on the two key factors - comfort and harmony. The psychological approach to the home interior includes two major functions. The most widespread and common is a harmonizing function when the decor of a room or the whole house reflects its owner's temperament, his perception of the outside world. The function of such a decor is to create the atmosphere of harmony and calm. Nontrivial solutions can hardly be appropriate. Such an approach actually assumes interior inactivity towards its owner. Because of optimal mixture of shades and structures of decoration materials, the interior is adapted to an owner and reflects his inner ego. The other function can be called stimulating. Such an approach presupposes a certain connection between the design and a human mind. Nowadays design plays an active part: it either favorably stresses owner's certain traits of character and temperament or it evens out unfavorable qualities. For example, such an interior can balance an impulsive choleric or encourage a melancholic who is inclined to depression. It is obvious that the popularity of feng-shui now is mostly determined by the variety of techniques available for organizing stimulating space. But feng-shui adherers state that favorable arrangement of space can magically impact not only on the minds of people who live in this space, but also the events in their lives, success in private and social life. It goes without saying that an ideal design should combine the two functions. But not every person can get a professional consultancy in the interior psychology or space planning from a master of feng-shui. Yet, one can learn and use the major aspects of personal approach to space arrangement on their own. The interior design starts with house planning, creating a certain inner space structure. As psychologists put it, such structuring is of paramount importance. It sets the rhythm of life in a house and often determines particular types of relationships that exist between house dwellers and between house dwellers and their guests. Though there are a lot of forms of house planning, there should be emphasized two major types: close and open interior.
