31-15 ASPECTE PRIVIND ISTORICUL AUTOMOBILULUI ROMÂNESC – Partea a III-a

ASPECTS OF HISTORY ROMANIAN CAR – part III

 

At the beginning of last century, Romania was one of the richest European countries, among the first 10 countries that have introduced the car since its inception.

It presents the first transport vehicles in Romania dates back to 1895 are represented by two hybrid trucks with steam. „The Karaso” Simplon exotic convertible is a car made in Resita, in the style roadsters from the 50s. Vintage cars are not just cars, they can be considered on its own history on wheels, ideal combination for nostalgic times in which power was aesthetics, elegance and refinement. The oldest car in the west is a nice Ford Model A, 1928. The tradition left by the big names in automotive construction must be respected, promoting the work of some young Romanian students from technical universities and their achievements: University „Ovidius” in Constanta, Technical University „Gh. Asachi” University and University of Pitesti.

27-19 CHINA – LA SUPERLATIV Partea a II-a

CHINA – AT ITS BEST – Part II
One of the contestants feared you 21st century economic market (because here are the biggest fights) is China. Among the most recent achievements of the Government in Beijing is „the three Gorges Dam” on the Yangtze River-6380 km-the third longest in the world, after the Amazon and the Nile. China’s model of economic progress transmits a significant lesson to all avid States economic charts, because progress has a price, a price so high that it cannot estimate the figures. Located in the Chinese capital, Beijing, Tian An Men Square is the biggest market in the world. Its shape is rectangular, measuring an area of 44 hectares, mainly its name and the gate that leads to the Forbidden City. China has become the second world economy taking the place of Japan in 2010, after its gross domestic Product (GDP) has exceeded that of the archipelago home islands throughout the year, according to figures announced by the Japanese Government. And the superlatives continue: high-speed rail network, the longest tunnels, skyscrapers, many other daring projects, etc., etc.
Keywords: Chinese superlatives, population, pollution, high speed trains, international trade, export, supercomputers, hydropower, navigable channels, art, skyscraper etc.
