چکیده
Ž . This paper reports the total NO column TNC measurements performed in Athens, Greece 2 during the period 1996–97. The measurements used a solid-state spectrometer and were based on the spectral absorption of beam solar irradiance in the visible region. This study investigates the diurnal and seasonal variations of the total NO column in the atmosphere above Athens. It is 2 Ž . found to be in the range 1–160 matm-cm average values , with large daily and seasonal variations. The highly probable link between this variability and synoptic conditions over Athens is discussed. q 2001 Elsevier Science B.V. All rights reserved.

متن کاملSuccessful management of an equine carpal chip fracture by intra-articularly injected adipose-derived stromal vascular fraction after arthroscopic removal
Carpal chip fractures are common causes of lameness in racehorses. Due to disadvantages in surgical management, adjuvant treatment modalities are usually necessary. Adipose-derived stem cells (ADSCs) have the potential to differentiate into other cell types including bone and cartilage cells. Adipose-derived stromal vascular fraction (SVF) is produced during ADSCs isolation from adipose tissue....
