Keystone (cask)

A keystone is a small wooden or plastic fitting used in ale casks.

For some years wooden casks have been effectively obsolete, with the majority now being aluminium or stainless steel, and a few sturdy plastic ones beginning to appear. Nevertheless, the standard tap is still designed to be hammered into yielding material, punching a hole as it goes. All modern casks, even the few wooden ones still in use, use a replaceable keystone to accept the tap.

The bung-hole of the cask is on one of the circular faces, near the rim. When the cask is in service, it is laid on its side with the bunghole at the lowest point on the circumference. The keystone is a small thick wooden or plastic disk inserted into the bunghole which completely seals the cask until it is needed.

The centre of the keystone is deliberately weakened, this area may be marked or unmarked and is called the tut. In the plastic variety it is much thinner than the surrounding material; if made of wood it is partially pre-cut so that it is easier to punch out. Some time before the cask is to be served, the end of the tap is placed against this weakened section and, with the aid of a mallet, driven through it. The shaft of the tap is tapered, so that as it is forced in fully it seals against the undisturbed outer part of the keystone. A small amount of beer may leak out during this process, but with sufficient skill and firm action with the mallet, no spillage at all can occur.

Pennsylvanian (train)

The Pennsylvanian is a 444-mile (715 km) daytime Amtrak train running between New York and Pittsburgh via Philadelphia. The trains travel across the Appalachian Mountains, through Pennsylvania's capital Harrisburg, the Pennsylvania Dutch Country, suburban and central Philadelphia, and New Jersey en route to New York. Trains run once daily in each direction. The entire train ride takes about 9 hours total, with 1.5 hours between New York and Philadelphia, 2 hours between Philadelphia and Harrisburg, and 5.5 hours between Harrisburg and Pittsburgh.

The Pennsylvanian is a once a day replacement of the Keystone service between New York and Pittsburgh, offering Business Class seating as an upgrade to the coach-only seating on Keystone trains. Prior to Amtrak, the route was known as the Duquesne, named after Fort Duquesne in Pittsburgh, and operated by the Pennsylvania Railroad. The Pennsylvanian began on April 27, 1980, as a state-supported daylight train between Philadelphia and Pittsburgh, with connecting service to New York. Amtrak would later extend the train to serve New York directly. Between 1998–2005 Amtrak shifted the endpoints west to Chicago and Philadelphia, providing daylight service to Cleveland, Ohio. In 2005 the Pennsylvanian reverted to a Pittsburgh–New York schedule. On its inauguration the Pennsylvanian used Amfleet equipment and continues to be so equipped.

Fable II Pub Games

Fable II Pub Games is an Xbox Live Arcade title that includes three pub game-styled minigames called Keystone, Fortune's Tower and Spinnerbox for the Xbox 360, developed by Carbonated Games under the supervision of Lionhead Studios, which all share functionality with Fable II. The games are included in both editions of Fable II. Fable II Pub Games was also free for those who pre-ordered Fable II from participating retailers.

Fable II

The Pub Games offer players a chance to win money and items for their Fable II character, to be given to them once their character has reached adulthood. For every piece of gold won in the tournament section of Pub Games, a piece of gold is added to the Fable II character's wallet, giving players a chance to have a rich character from the start of the game. Conversely, if the player accumulates debt in the Pub Games, negative consequences will befall their character. Fifteen unique items can also be won in the Pub Games' tournaments, ranging from weapons to clothing or tattoos that can be used by their Fable II character.

Cask (company)

Cask is a cloud-based Big Data application platform for developers. Rather than simply providing another cloud service for writing and running Hadoop jobs, Cask allows developers to more easily build, deploy and manage Big Data applications on top of the components within the Hadoop ecosystem.

Naming

The word “cask” signals that Cask’s software provides containers, a way for different types of applications to run in concert and share data, for instance. “Cask is short, sweet and ‘developer-y,’” he (Jonathan Gray, CEO) said.

Product

The Cask Data Application Platform (CDAP) is an open source project for distributed data and applications. CDAP is a layer of software running on top of Hadoop platforms. Cask Coopr is open source cluster management software that provisions, manages and scales clusters on public clouds and private clouds. Tigon is a distributed framework built on Apache Hadoop™ and Apache HBase™ for real-time, high-throughput, low-latency data processing and analytics applications.

CASK

Peripheral plasma membrane protein CASK is a protein that in humans is encoded by the CASK gene. This gene is also known by several other names: CMG 2 (CAMGUK protein 2), calcium/calmodulin-dependent serine protein kinase 3 and membrane-associated guanylate kinase 2.

Gene

This gene is located on the short arm of the X chromosome (Xp11.4). It is 404,253 bases in length and lies on the Crick (minus) strand. The encoded protein has 926 amino acids with a predicted molecular weight of 105,123 Daltons.

Function

This protein is a multidomain scaffolding protein with a role in synaptic transmembrane protein anchoring and ion channel trafficking. It interacts with the transcription factor TBR1 and binds to several cell-surface proteins including amyloid precursor protein, neurexins and syndecans.

Clinical importance

This gene has been implicated in X-linked mental retardation, including specifically mental retardation and microcephaly with pontine and cerebellar hypoplasia.

Interactions

CASK has been shown to interact with:

Stag's Leap Wine Cellars

Stag's Leap Wine Cellars is a winery founded by Warren Winiarski in 1970 and based in the Stags Leap District of Napa Valley, California. The winery was sold to a joint venture by Chateau Ste. Michelle of Woodinville, Washington, and Marchesi Antinori Srl of Italy for $185 million in August 2007. It is 50% owned by the Tobacco/Food Conglomerate Altria.

History

Warren Winiarski was introduced to wine while on a year-long trip to Italy studying the work of Niccolò Machiavelli. After returning to Chicago, he found an interest in wine and in the early 1960s began to experiment with making his own wine at home. He moved to the Napa Valley with his wife and children in 1968, and took up a job with Chateau Souverain. Following this, he moved to work at the newly started Robert Mondavi Winery.

Stag's Leap Wine Cellars was founded in 1970 after Winiarski purchased a 44 acre block of land for under $200,000 that was situated next to the vineyard owned by modern Napa Valley Cabernet winegrowing pioneer Nathan Fay. Winiarski decided on purchasing land in the region after tasting a homemade wine from Nathan Fay's vineyard, after tasting the wine Winarski stated “I said to myself, Eureka! That’s it. This wine satisfied what I hoped was possible in the Napa Valley. It had not only regional character but also elements of classic or universal character.”
