Rift

In geology, a rift is a linear zone where the Earth's crust and lithosphere are being pulled apart and is an example of extensional tectonics.

Typical rift features are a central linear downfaulted depression, called a graben, or more commonly a half-graben with normal faulting and rift-flank uplifts mainly on one side. Where rifts remain above sea level they form a rift valley, which may be filled by water forming a rift lake. The axis of the rift area may contain volcanic rocks, and active volcanism is a part of many, but not all active rift systems.

Major rifts occur along the central axis of most mid-ocean ridges, where new oceanic crust and lithosphere is created along a divergent boundary between two tectonic plates.

Failed rifts are the result of continental rifting that failed to continue to the point of break-up. Typically the transition from rifting to spreading develops at a triple junction where three converging rifts meet over a hotspot. Two of these evolve to the point of seafloor spreading, while the third ultimately fails, becoming an aulacogen.

Oculus Rift

The Rift is a virtual reality head-mounted display developed by Oculus VR. It was initially proposed in a Kickstarter campaign, during which Oculus VR (at the time an independent company) raised US$2.5 million for the development of the product.

The Rift is scheduled for release on March 28, 2016, making it one of the first consumer-targeted virtual reality headsets. It has a resolution of 1080×1200 per eye, a 90 Hz refresh rate, and a wide field of view. It has integrated headphones which provide a 3D audio effect. The Rift has rotational and positional tracking. The positional tracking is performed by a USB stationary IR sensor, which normally sits on the user's desk, allowing for using the Rift while sitting, standing, or walking around the same room.

The Rift has gone through various prototype versions in the years since the Kickstarter campaign, around 5 of which were demonstrated to the public. Two of these prototypes were made available for purchase as 'development kits', DK1 in late 2012 and DK2 in mid 2014, to give developers a chance to develop content in time for the Rift's release. However, both were also purchased by a large number of enthusiasts who wished to get an early preview of the technology.

Rek people

The Rek is an ethnic group in South Sudan, a subgroup of the Dinka. Its members speak South-Western Dinka, also called Rek, a Nilotic language. Many members of this ethnicity are Christians. Some estimates put the Rek population at or exceeding 500,000 people.

Tsoureki

Tsoureki (Greek: τσουρέκι), also known as شوريك (Arabic), panarët (Arbërisht), choreg or "chorek" (Armenian չորեկ), çörək (Azerbaijani), kozunak (Bulgarian козунак), cozonac (Romanian) or çörek (Turkish)), is a sweet, egg-enriched bread, rooted in the cuisines of Western and Central Asia. It is formed of braided strands of dough. There are also savoury versions.

Such rich brioche-like breads are also traditional in many other countries, such as Hungary and the Czech Republic. Examples of similar breads from other cultures are badnji kruh in Croatian cuisine, folar de páscoa in Portuguese cuisine, Brioche in French, kulich in Russian cuisine, panettone in Italian cuisine and challah in Jewish cuisine.

Greek traditions

Rich brioche-like breads (often braided) are known by various Greek names that represent three major holidays for Greeks: Easter, Christmas and New Year's. There are many local varieties of these festive breads, based on milk, flour, eggs, sugar, yeast, butter, and a flavoring which can be mahleb, Chian mastic or cardamom. The butter is added after kneading: the dough is stretched, brushed with melted butter, folded and stretched again repeatedly, until all the butter is incorporated. The result of this technique is that the baked bread separates easily into strands. A good tsoureki should be soft, moist and fluffy, yet stringy and chewy.
