The effects of coronary pressure on coronary stenosis resistance were studied in 13 open-chest dogs. A noncircumferential stenosis was produced in the circumflex coronary artery by placing sutures into either side of the artery and invaginating a portion of the arterial wall by tying the sutures. Coronary pressure both proximal and distal to the stenosis and coronary flow were measured. Coronar...

Pressure is a powerful tool to unveil the profound nature of electronic properties in a variety of organic conductors. Starting from technology of high pressure, we plan to review what kind of physics or phenomena have previously been discussed.

To the Editor: In order to know whether the apparently striking effects of early treatment with an angiotensin receptor blocker after ischemic stroke1 were due to the timing of treatment, the drug class, or confounding variables, important information is missing in the article. We note that blood pressure values were similar in the treatment and the study population, in both the acute and the f...

there are many problems in the treatment of hypertension, so we use alternative medicine to achieve better results to solve these problems. in this article we describe a hypertensive patient resisted to conventional drugs and she had some other somatic and psychotic symptoms and was treated by homeopathy, a method of alternative medicine.

The influence of the firing conditions on the nanoscale structure of the grain boundaries and on the magnetic properties of polycrystalline MnZn-ferrites is investigated, on specimens of nearly identical microstructures. High oxygen partial pressures favor accumulation of impurity ions at the triple points. Under appropriate oxygen pressures homogeneous accumulation of impurities along the grai...

We studied electrical resistivity and the Hall coe cient of single-crystalline samples of an oxide superconductor Sr2RuO4 under hydrostatic pressures up to 1.2 GPa. The value of Tc decreases by 36 % at 1.2 GPa, while no appreciable change in the resistivity or the Hall coe cient has been observed. At room temperature an unexpected increase of resistivity along the c axis occurs with increasing ...

The results of high hydrostatic pressure studies of martensitic transformations in alloys with special emphasis to shape memory alloys (SMA) are reviewed. Experimentally detected positive and negative signs of MS temperature pressure shift and phase p-T diagrams are discussed. High pressure induced shape memory effect and baroelasticity are considered to be the essential phenomena illustrating ...

− Static expansion systems are used to generate known pressures in the high and medium vacuum range. In these systems the volume ratios are the crucial parameters and have to be determined very accurately. For this task different methods can be used. We have used the gas accumulation method with a dead weight pressure balance, a force-balanced piston gauge (FPG) and a differential pressure tran...
