Acoustic determination of early stages of intravascular blood coagulation.

11 Oct 2008 The blood coagulation system (BCS) is a complex biological system playing a principal role in the maintenance of haemostasis. Insufficient activity of the BCS may lead to bleeding and blood loss (e.g. in the case of haemophilia). On the other hand, ... Read more...

Carotid intima-media thickness measurements: techniques and clinical relevance.

29 Sep 2008 Atherosclerosis is a systemic disease that is responsible for most cardiovascular events and stroke. Epidemiologic studies and intervention trials based on the incidence of acute vascular disease end points require years of follow-up, the ... Read more...

Acoustic oscillations and elastic moduli of single gold nanorods.

21 Sep 2008 We present the first acoustic vibration measurements of single gold nanorods with well-characterized dimensions and crystal structure. The nanorods have an average size of 90 nm x 30 nm and display two vibration modes, the breathing mode and the ... Read more...

Technical information about 'Acoustics'

Definition: The branch of physics that deals with sound and sound waves. In medicine it is often applied in procedures in speech and hearing studies. With regard to the environment, it refers to the characteristics of a room, auditorium, theatre, building, etc. that determines the audibility or fidelity of sounds in it.
