A wiperless windshield is a windshield that uses a mechanism other than wipers to remove snow and rain from the windshield. The concept car Acura TL features a wiperless windshield using a series of jet nozzles in the cowl to blow pressurized air onto the windshield.
Half sibling A half sibling (half brother or half sister) is a sibling with one shared biological or adoptive parent. A half sibling that shares the same mother (but different fathers) is known as a uterine sibling, whereas one that shares the same father is known as an agnate sibling.
A brother to sister (sibling to sibling DNA Test) works by testing a very large number of different DNA points (known as loci) in each person. Full siblings share a lot more DNA in common than do unrelated persons, and also, half siblings share more DNA in common than unrelated persons, but not as much as full siblings. So this test looks at the amount of DNA sharing and uses DNA statistics to evaluate the amount of DNA sharing to deduce biological relationship.
