Maori , member of a Polynesian people of New Zealand. This historical account provides the basis for traditional Maori social organization and is generally supported by archaeological discoveries, which have dated Maori arrival in New Zealand to about ce. Members of each tribe iwi recognized a common ancestry which might be traced through either or both parents and common allegiance to a chief or chiefs ariki. Traditionally, at the day-to-day level, the most important social groups were the hapuu subtribe , which was the primary landholding group and the one within which marriage was preferred, and the whaanau , or extended family. This social order was in force when Abel Tasman , the first European contact, arrived off the coast of New Zealand in December He did battle with a group of Maori on South Island and left the area largely unexplored.

Review of Consumer and Professional Grout Sealers
The Aboriginal Tasmanians Palawa kani : Palawa or Pakana  are the Aboriginal people of the Australian island of Tasmania , located south of the mainland. For much of the 20th century, the Tasmanian Aboriginal people were widely, and erroneously, thought of as being an extinct cultural and ethnic group that had been intentionally exterminated by white settlers. First arriving in Tasmania then a peninsula of Australia around 40, years ago, the ancestors of the Aboriginal Tasmanians were cut off from the Australian mainland by rising sea levels c.

By , George Augustus Robinson , sponsored by Lieutenant-Governor George Arthur , had persuaded the approximately surviving Aboriginal Tasmanians to surrender themselves with assurances that they would be protected, be provided for and eventually have their lands returned to them.
Calcium Hydroxide-Based Root Canal Sealers: A Review
A variety of steam cleaners are available for use on flooring, and while some as marketed as being designed especially for hardwood, these claims should be viewed very cautiously. Hardwood is naturally a very absorbent material, and exposure to water can cause it to plump, warp, twist, and mold. A steam cleaner by its very nature uses water heated to a very hot vapor to clean and disinfect the surface of a floor. This vapor can get down into cracks and crevices to kill germs and bacteria, but when used on a hardwood floor, the moisture can stay down in the cracks and crevices, leading to problems in the future.
