It has to do something with ceramics or clay.
3 years ago, I was diagnosed - hypertension with a reading of 160/100I used to feel dizzy a lot, my legs had awful cramps, and levels were very low in my potassium, causing my fingers and toes to always cramp togetherOne day I started to feel really faint while I was driving with my daughter in the back seat and I passed out, hitting 3 cars and ending up in a ditchThat moment,I knew I had to do something because my meds weren't workingI heard about this diet from a friend and thought I'd give it a shotThe results have been remarkableIn just 21 days, I honestly can't remember feeling this good, my blood pressure went from 175/110 to 125/70.
Its normal to have a blood pressureToo low is probably OK Too high is nasty.
Refractory materials retain their strength at high temperaturesThey are used to make crucibles and to make refractory linings, which line furnaces, kilns and incineratorsThe oxides of magnesium (magnesite) and calcium (lime) are the most important refractory materials, though fireclay is widely used as wellZirconia is used when the material must withstand extremely high temperaturesSilicon carbide is another refractory materialIt is very strong at high temperatures, but will burn in the presence of oxygen, if the protective silica coating comes offRefractories must be chosen according to the conditions they will faceFor example, carbon cannot be used when it will be in contact with oxygen, as it will burnAcidic refractories cannot be used in a basic environment and basic refractories cannot be used in acidic environment because they will be erodedZircon, fireclay and silica are acidic, dolomite and magnesite are basic and alumina, chromite, silicon carbide, carbon and mullite are neutralRefractory materials must be strong at high temperatures, resistant to thermal shock, chemically inert, and have low thermal conductivities and coefficients of expansion.
A normal systolic pressure should not exceed 140, and a normal diastolic pressure is no more than 90An increase in both pressures can mean disasterIn recent studies, persons below 65 or 70 who are diagnosed with hypertension reported increase incidents of diastolic high blood pressureThis higher rate of diastolic pressure causes adverse effects on the brain, heart and kidneyPatients of diastolic high blood pressure are advised to lower diastolic pressure by maintaining below 90Systolic pressure is also required to be lowered though a top priority is focused on diastolic pressureCauses of diastolic high blood pressure include aging of the heart and its natural effectsWhen a person grows old his heart muscles get weary and eventually stiffen making it harder for the heart to fill in blood appropriatelyDiastolic high blood pressure, if not treated well, may lead to diastolic heart failureDiagnosis of diastolic high blood pressure may risk the patient of diseases and illnesses like CAD or coronary heart disease, aortic stenosis, hypertrophic cardiomyopathy, and other pericardial diseasesAside from aging, poor lifestyle like smoking and drinking, high cholesterol levels, obesity, high salt consumption, prior cardiac surgery, viral infection, family history and diabetes are also leading contributors to the occurrence of diastolic high blood pressure.
