Despite a surge in oil prices this week on expectations of a major escalation in the Middle East, the benchmarks were set for their fourth weekly loss in a row as demand concern outweighed the war [url=https://www.nike-dunk.es]dunk panda[/url] premium.Both Brent crude and West Texas Intermediate were up earlier in the day, but overall prices were down on last week, with Reuters citing a survey revealing a slowdown in manufacturing activity across most of the world and the third annual road traffic decline in China.PMI readings for July showed a slowdown in activity in Asia, Europe, and the United States, with the U.S. drop especially steep, reaching the lowest in eight months on a decline in new orders, to a reading of 46.8.The eurozone was doing even worse, with PMI across the single-currency bloc logging a reading of just 45.8 in July.

Привет, любители приключений! На прошлой неделе я вернулся из Польши, и одним из самых ярких моментов поездки стало посещение Вроцлава. Читал на [url=http://tripland.info/category/puteshestviya-po-miru/]Tripland[/url] про скульптуры гномов, которые разбросаны по всему городу, и решил устроить себе квест, чтобы найти их все. Это было так увлекательно, что я познакомился с местными жителями, которые помогали мне искать гномов. Без советов сайта я бы точно упустил такую возможность!
