We have developed a long-range Brillouin distributed sensor featuring 100 km measuring distance with 2 meter resolution. To our knowledge, this is the first time that a high-resolution setup reaches the barrier of 100 km measurement range. The key improvements with respect to previous configurations are explained.
The purpose of this cross-sectional study was to investigate the change in 100-km running performance and in the age of peak performance for 100-km ultramarathoners. Age and running speed of the annual fastest women and men in all 100-km ultramarathons held worldwide between 1960 and 2012 were analyzed in 148,017 finishes with 18,998 women and 129,019 men using single, multivariate, and nonline...
Currently production climate simulations typically occur at rather coarse resolution, withO(100 km) separation between grid points. This choice of resolution is a direct result of limited computing resources. While 100 km resolution is sufficient to resolve global and large continental scale features and trends in the climate system, it is insufficient to resolve regional features. Encouraged b...
Purpose. Response to an ultraendurance competitive race on thiols redox status, reactive oxygen species (ROS) production, and oxidative stress (OxS) was investigated according to duration. Methods. Twenty-four elite runners were examined: six completed 50 km and eighteen 100 km. Blood and urine samples were collected before and immediately after the race. Erythrocytes and plasma aminothiols by ...
در تحقیق حاضر، ?-آمیلاز حاصل از باسیلوس سابتیلیس بر روی سطح سیلیکاژل، از طریق برقراری پیوند کووالانسی تثبیت شد و سپس اثر میدان مغناطیسی ایستا (mt13) برتثبیت و فعالیت ?-آمیلاز (تثبیت شده و آزاد) در دمای c°25 و phهای مختلف (0/6، 5/6، 9/6و 6/7) مورد بررسی قرار گرفت. ?-آمیلاز (آنزیم آزاد( و واکنش آنزیم-سوبسترا (آنزیم آزاد و تثبیت شده) به ترتیب برای مدت 100 دقیقه و 5/1 دقیقه در دمای c°25 در معرض مید...
