اسانس های گیاهی با اثرات شناخته شده ای که روی آفات گذاشته اند، می توانند جایگزین مناسبی برای آفت کش های شیمیایی رایج باشند. در این تحقیق، اثرات سمیت تدخینی، تماسی و دورکنندگی اسانس صمغ، میوه و برگ بنهpistacia atlantica desf. subsp. kurdica (zohary) rech. f. روی حشرات کامل سوسک چهارنقطه ای حبوبات callosobruchus maculatus (fabricius, 1775) و شناسایی ترکیبات، اثرات سمیت تدخینی، تماسی و دورکنندگی ا...
During the Mediterranean Intensive Oxidant Study (MINOS) in August 2001 a total of 14 measurement flights were performed with the DLR Falcon jet aircraft from Heraklion, Crete. One objective of this campaign was to investigate the role of long-range transport of pollutants into the Mediterranean area. An analysis of 5-day back trajectories indicates that in the lower troposphere (0–4 km) air ma...
BACKGROUND This study was conducted to assess intra-observer and inter-observer agreements for the measurement of dual-input whole tumor computed tomography perfusion (DCTP) in patients with lung cancer. METHODS A total of 88 patients who had undergone DCTP, which had proved a diagnosis of primary lung cancer, were divided into two groups: (i) nodules (diameter ≤3 cm) and masses (diameter >3 ...

In March 1997 NLR investigated the icing atmosphere for aircraft by flying with an instrumented research aircraft through clouds. Liquid water content, droplet diameter distributions and air temperature were measured. Large droplets were found in air masses with a limited extent. Results from the measurement campaign are presented and compared with limits in aircraft and helicopter certificatio...
