Do chamfers reduce stress concentration? Fillets generally give a lower stress concentration factor than chamfers . Chamfers are more forgiving when fitting mating parts. How do you find the concentration factor? The concentration factor formula, based on the percent recovery for an RO system, is useful for calculating the concentration of dissolved substances in the […]

What happens if an egg does not fertilize? If the egg is not fertilized or does not implant, the woman’s body sheds the egg and the endometrium. This shedding causes the bleeding in a woman’s menstrual period. When a fertilized egg does implant, a hormone called human chorionic gonadotropin (hCG) begins to be produced in […]
