Heart palpitations are described as feeling like your heart is racing or pounding. Palpitations can be caused by anxiety, panic disorders, overeating, pregnancy, and abnormal heart rhythms (arrhythmias). Most palpitations are not serious, however, palpitations caused by a heart condition like atrial fibrillation or Afib can be serious and require medical treatment.
WEIGHING BY DIFFERENCE (From Dr. David Chesney) Weighing by difference is the most accurate method to measure quantitatively the mass of a solid sample. This procedure involves repetitive weighings of a weighing bottle containing a quantity of solid reagent. As the solid is removed to another vessel, the mass of the weighing bottle contents decreases.
The BMI, or Body Mass Index, is a number calculated by taking your weight in kilograms and dividing it by height in meters squared. For reference, according to BMI, male who is around 5â8â should weigh between 130 and 165 pounds. A 5â3â woman should weigh between 105 and 140 pounds.
