During the last interglacial period, the Red Sea coast of Eritrea was occupied by early anatomically modern humans. It is believed that the area was on the route out of Africa that some scholars suggest was used by early humans to colonize the rest of the Old World. In 1999, the Eritrean Research Project Team composed of Eritrean, Canadian, American, Dutch and French scientists discovered a Paleolithic site with stone and obsidian tools dated to over 125,000 years old near the Bay of Zula south of Massawa, along the Red Sea littoral. The tools are believed to have been used by early humans to harvest marine resources like clams and oysters.
What Team was composed of Eritrean, Canadian, American, Dutch and French scientists?
A: Eritrean Research Project Team

Two recent discoveries indicate probable very early settlements near the Thames in the London area. In 1999, the remains of a Bronze Age bridge were found on the foreshore north of Vauxhall Bridge. This bridge either crossed the Thames, or went to a now lost island in the river. Dendrology dated the timbers to 1500 BC. In 2010 the foundations of a large timber structure, dated to 4500 BC, were found on the Thames foreshore, south of Vauxhall Bridge. The function of the mesolithic structure is not known. Both structures are on South Bank, at a natural crossing point where the River Effra flows into the River Thames.
The remains of an unknown ancient structure found on the River Thames foreshore dated back to approximately what year?
A: 4500 BC

Each trace consists of a flat, narrow part of the copper foil that remains after etching. The resistance, determined by width and thickness, of the traces must be sufficiently low for the current the conductor will carry. Power and ground traces may need to be wider than signal traces. In a multi-layer board one entire layer may be mostly solid copper to act as a ground plane for shielding and power return. For microwave circuits, transmission lines can be laid out in the form of stripline and microstrip with carefully controlled dimensions to assure a consistent impedance. In radio-frequency and fast switching circuits the inductance and capacitance of the printed circuit board conductors become significant circuit elements, usually undesired; but they can be used as a deliberate part of the circuit design, obviating the need for additional discrete components.
In a multi-layer board, what metal would a ground plane be mostly made out of?
A: copper

Namibia's primary tourism related governing body, the Namibia Tourism Board (NTB), was established by an Act of Parliament: the Namibia Tourism Board Act, 2000 (Act 21 of 2000). Its primary objectives are to regulate the tourism industry and to market Namibia as a tourist destination. There are also a number of trade associations that represent the tourism sector in Namibia, such as the Federation of Namibia Tourism Associations (the umbrella body for all tourism associations in Namibia), the Hospitality Association of Namibia, the Association of Namibian Travel Agents, Car Rental Association of Namibia and the Tour and Safari Association of Namibia.
What does act 21 in Namibia regulate?
A:
tourism industry
