There is a conflicting literature regarding the possible presence of adrenergic innervation of the retinal circulation. The effect of a histologically confirmed left superior cervical ganglionectomy on the total retinal blood flow in eight anaesthetised female cynomolgus monkeys was determined. Near total unilateral ocular sympathetic denervation was confirmed by ipsilateral miosis, supersensit...
In 10 cardiac patients in whom an organic lesion of the mitral valve was exluded by standard investigation procedures during which a diagnostic transseptal catheterization for pressure measurements in the left heart was performed, the authors placed a directional Doppler ultrasonic catheter tip velocimeter at the site of the mitral ring and recorded the mitral flow velocity traces. The pattern ...
In this study, a thermal spring located in the Gulf of Gera (Lesvos Island) is investigated terms radiotracers, water flow velocities and acoustic back-scattering properties by situ observations. Water characteristics were deduced using deployments three marine sensors: an Acoustic Doppler Velocimeter (ADV), High-Frequency Current Profiler (ADCP), medium-resolution underwater gamma-ray detectio...
Bu çalışma kapsamında, açık kanalda kararlı (zamanla değişmeyen) akım koşullarında oluşan hızlarının deneysel olarak incelenmesi amaçlanmıştır. doğrultuda Dokuz Eylül Üniversitesi İnşaat Mühendisliği Hidrolik Laboratuvarı’nda yer alan kanal deney düzeneğinde hız ölçümleri yapılmıştır. Ölçümler sırasında ultrasonik yöntemle ölçümü yapan UVP (Ultrasonic Velocity Profiler) ve ADV (Acoustic Doppler...
