Naum Gabo‚ a pioneer of constructive art‚ was born Naum Neemia Pevsner in Russia in 1890. He began making constructed sculpture in Norway in 1915‚ when he took the name of Gabo. He and his brother Antoine Pevsner‚ returned to Russia at the time of the Revolution. In 1920 Gabo wrote the Realistic Manifesto‚ an expression of the aims and philosophy behind his art‚ which was signed by Antoine and was posted on the streets of Moscow. In 1922 Gabo left Russia for Berlin‚ to exhibit in the Erste Russische

appoximation (m1r12 + m2r22). Set Up Procedure First we measured the weights of two masses and wingnuts that secure them. Then we placed one of the masses on the very end of a horizontal rod on the centripetal force apparatus‚ 0.162 m away from the centre of the rod‚ and the other mass 0.115 m away from the centre of the rod. Then we attached a 0.2 kg mass to the bottom of a string and wound the string around the vertical shaft of the apparatus‚ so that the bottom of the weight rose to the bottom edge of

During the last century‚ nuclear power has been established as a reliable source of energy in the major industrialized countries. Nuclear power plants provide about 17 percent of the world’s electricity. In the United States‚ nuclear power supplies about 15 percent of the electricity overall. Although no new plants are scheduled to be built in the United States‚ nuclear power is growing to be a popular producer of power. It has recently enjoyed a revival in attention and research due to the environmental

Thermal hydraulics analysis of supercritical water reactor core design Jianguo Zhong‚ Michael Podowski Abstract: This paper started with a literature survey of development the supercritical flow reactor core design‚ various coolant flow path designs were discussed: conventional one-pass flow arrangement‚ two-pass and the three-pass coolant flow geometry. A simple 1-D model was developed for the one-pass and two-pass flow design to find the maximum flow bulk temperature and case temperature in

Abstract: The objective of the experiment is to learn how to use a microscope while viewing various types of bacteria cultures. Prepared slides are used to view bacterial cultures under a microscope that would normally be invisible to the naked eye. Bacterial shapes and arrangements or morphology are observed in prepared slides and fresh yogurt culture. Purpose: The experiment is meant to determine the shapes of bacteria under different magnifications when using a microscope; 10X‚ 40X‚ and 100X

Bifocals are eyeglasses with an upper and lower half‚ the upper for distance‚ and the lower for reading. Bifocals are commonly prescribed to people with presbyopia‚ a condition that Franklin suffered. Franklin wrote‚ in August 1784 to his friend George Whatley‚ that he was "happy in the invention of double spectacles‚ which serving
