Tulikivi Fireplaces Radiate a Pleasant Warmth. When you sit near a Tulikivi fireplace, you experience a pleasant feeling of warmth. This penetrating yet comfortable radiant heat is the same heat that travels to us from the sun as infra red light (infra red radiation).This sunshine from a Tulikivi is not dependant on the air temperature to make its effects felt.arm air is unable to penetrate the outer layer of the epidermis, which acts as an insulator. The pleasant feeling caused by radiant heat from a stone fireplace is further enhanced by the fact that radiant heat can penetrate the outer layer of the skinâs epidermis and be absorbed directly by the blood stream.

What is a STEMI? ST-Elevation Myocardial Infarction (STEMI) is a very serious type of heart attack during which one of the heartâs major arteries (one of the arteries that supplies oxygen and nutrient-rich blood to the heart muscle) is blocked. ST-segment elevation is an abnormality detected on the 12-lead ECG. It is a profoundly life-threatening medical emergency and usually associated with a disease process called atherosclerosis (coronary artery disease). You can find a useful video about heart disease and heart attacks at the Khan Academy.
