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 rest of the world favors measuring by weight. Since food items vary in density, you can't use a simple arithmetic formula to translate from one to the other. To take an obvious example, a cup of alfalfa sprouts will weigh much less than one of sugar. Less obviously, all-purpose white flour weighs less than wheat meal or rye flour. Hence the need for this table. You should use the table as a rough guide only, as several factors might affect the results: How firmly the flour is packed, how finely the cheese is shredded, and so on.
