Liquid State Physics in Turkey

22. Liquid State Symposium (22. Sıvı Hal Senpozyumu) took place on 7th December 2018 in Piri Reis University.
It was very proud to be together with the physicist academics I knew and admired since my undergraduate years.
I find myself lucky to see the Prof. Zehra Akdeniz that I have always admired and exemplified. I could finally meet Prof. Nihat Berker who is not only a famous physicist but also an intellectual on comparative literature readings.

Thanks to Dr. Ozan Sarıyer and Dr. Gulsen Evingur for organizing this meeting.

Prof Pekkan presented biological flow researches of his lab, and I presented a sample case of a pediatric aortic blood flow comparison study which is done with the great help of Dr. Ece Salihoglu.

Simulate the Physiology & Understand the Pathology


Computational Life is a young company which has the specialty on computational flow simulations and mathematical models for the medical technology field.

The validated software Digital Avatar Platform (DAP) of Computational Life is modeling human and animal body mathematically. It is testing physiological scenarios for drugs, medical devices and treatment methods.

Circulation system, cerebrospinal fluids, transport of pharmaceutical products throughout the body can be simulated for the human and animal body with DAP. It can also be modified due to the experiment.

They replied to me with a very warm and energetic mood when I wrote them. It is great that there are enthusiastic people in the medical technology field. I am sure that I will hear more about the news of Computational Life in the next days.

Thanks to Christian Contarino, Davide Chieco and Carlo Rivis for their innovative platform which brings a great help for clinicians, researchers, and engineers.

Please check their website for more information.


Wall Shear Stress

Pediatric re-stenosed pulmonary artery model is depicted with marked points of unstable wall shear stress (WSS) which brings about the thinner layers by platelets. This means the loss of smooth muscle cells and remodeling risk. Sudden bends and tapering in the geometry induces high velocity gradients and high wall shear stress.

Laser Doppler Velocimetry

Laser Doppler velocimetry is used in hemodynamics research as a technique to partially quantify blood flow in human tissues such as skin. Within the clinical environment, the technology is often referred to as laser Doppler flowmetry (LDF). The beam from a low-power laser (usually a laser diode) penetrates the skin sufficiently to be scattered with a Doppler shift by the red blood cells and return to be concentrated on a detector. These measurements are useful to monitor the effect of exercise, drug treatments, environmental, or physical manipulations on targeted micro-sized vascular areas.

The laser Doppler vibrometer is being used in clinical otology for the measurement of tympanic membrane (eardrum), malleus (hammer), and prosthesis head displacement in response to sound inputs of 80- to 100-dB sound-pressure level. It also has potential use in the operating room to perform measurements of prosthesis and stapes (stirrup) displacement.
