Background It is taken for granted that glaucomatous damage is caused by changed haemodynamics of the retrobulbar vessel system besides other factors such as, for example, an elevated intraocular ...

A flow measurement project on a Nottinghamshire river was compounded by potential pollution problems at a wildlife sanctuary. Flowline was called in to provide a metering station. Minimising the risk ...

Recent advances in flow sensing have resulted in more accurate, durable, and economical meters. Increasingly important is the ability to interface meters with a computer for instantaneous flow readout ...

In daily clinical practice, the possibilities of evaluating the quality of the microcirculation of certain territories of ‘vascular’ patients are relatively limited compared with the many tools for ...

Coronary flow reserve (CFR) is a key sign of coronary artery disease, namely how the coronary arteries that feed blood to the heart may adapt to various physiological situations such as exercise, ...
