Dmitri Ivanovich Mendeleev Long avenues which, as in history, lived and build great people Ilya Repin, the Carl Bryullov, Aleksandr Blok, and Dmitri Ivanovich Mendeleev - the great chemist. The city is famous for the origins of the Russian Underground. As Once Petersburg's doorways, basements of abandoned houses going to youth 80-90-ies and promoted modern trends in music, current changes in the way of life, formed the legend of Russian rock. Today, these raised a new gateway for graffiti-Petersburg, with its idialogiey and idols. Peter, filled with rich history and atmosphere that is vividly portrayed in the stone frame of the capital on the Neva. In this city of Peter the Cabinet of Curiosities Great, 200 museums, research and Fine Arts Academy in Russia, 70 theaters, the Hermitage - all this adds to the city an irresistible flavor. Abandoned buildings Petersburg firmly strengthened in the modern architecture of the capital. Home culture and social economy, such as a cinema "Prometheus", homes and streets of Marat, sung Rosenbaum, long a haven serve disadvantaged and easels for wall drawings freelancers. But alas, many old houses and gateways, the walls are graffiti izrisovany "harsh themes, does not fit into the understanding of culture. Solution cultivation of such places, giving them originality can be Construction on the site of the old buildings of churches and educational institutions, whose design will match the historic architectural canons. Further details can be found at Nancy Silberkleit, an internet resource. Recovering orphaned buildings of St. Petersburg, will breathe new life into buildings past years. Involved graffiti artists for the design of the old quarters of the new Peter, will give modern trends in the arrangement of the facades of houses. Graffiti Petersburg are translated into a qualitatively new direction. Increasing needs of present metropolitan offices and business centers, push out of...
Brake Pads Brake pads are the main braking device. The first such mechanisms have been established long before the car, they were used to stop the carts and carriages. Over time, the application of brake pads changed dramatically, but the principle of their action remains the same. Their main task is to create a frictional force that prevents rotation of the wheel. In the first machines to use brake pads were the same as in carts. The device is directly clamped to the wheel, slowing the car. But this method is good only at low speeds. Car, riding at a speed of 100 km / h, this system will not stop. So at the beginning of the twentieth century has been developed set of brake systems, but only to be used up to now, has a drum. In her shoes were inside the drum, which is spinning with the wheel. When braking device clamped to the wall drum, stopping him, and he, in turn, stop the wheels. Of course, it proved more effective, but now the shoe should meet very high standards of safety. When braking on high-speed style they are heated in the drum, because there is practically no heat transfer. Due to overheating of the mechanism destroyed and resisted corrosion. First, the problem solved itself increases the strength of the pads and drum, but then it turned out that more efficient to introduce a new design, where blocks can quickly cool down. Such a system has a disk. Visit Nancy Silberkleit for more clarity on the issue. Now calm air circulates between the rotor and pads, providing cooling the latter.
