Till

Till or glacial till is unsorted glacial sediment.

Till is derived from the erosion and entrainment of material by the moving ice of a glacier. It is deposited some distance down-ice to form terminal, lateral, medial and ground moraines.

Till is classified into primary deposits, laid down directly by glaciers, and secondary deposits, reworked by fluvial transport and other processes.

Processes

Glacial drift is the coarsely graded and extremely heterogeneous sediment of a glacier; till is the part of glacial drift deposited directly by the glacier. Its content may vary from clays to mixtures of clay, sand, gravel, and boulders. This material is mostly derived from the subglacial erosion and entrainment by the moving ice of the glaciers of previously available unconsolidated sediments. Bedrock can also be eroded through the action of glacial plucking and abrasion and the resulting clasts of various sizes will be incorporated to the glacier's bed.

Eventually, the sedimentary assemblage forming this bed will be abandoned some distance down-ice from its various sources. This is the process of glacial till deposition. When this deposition occurs at the base of the moving ice of a glacier, the sediment is called lodgement till. Rarely, eroded unconsolidated sediments can be preserved in the till along with their original sedimentary structures. More commonly, these sediments lose their original structure through the mixture processes associated with subglacial transport and they solely contribute to form the more or less uniform matrix of the till.

Ö till ö

ÖTILLÖ (Swedish for "Island to island") is a one-day swimrun race in the archipelago of Stockholm, Sweden. You compete in teams of two. The aim of the race is to get from Sandhamn to Utö, via 24 islands, by running across them and swimming between them. The total distance is 75 kilometres of which 10 km are open-water swimming and 65 km are trail-running. The first race was produced in 2006. The largest islands to run across are Runmarö, Nämdö and Ornö. In 2012 ÖTILLÖ was ranked as one of the toughest endurance challenges of the world by CNN.com. ÖTILLÖ is the first race and the origin to the growing movement of Swimrun. ÖTILLÖ is considered to be the World Championship of Swimrun even though it is not part of a federation.

ÖTILLÖ is produced by Michael Lemmel & Mats Skott (pre-marriage Andersson), former World Class Adventure Racers.

Cash register

A cash register, also referred to as a till in the United Kingdom and other Commonwealth countries, is a mechanical or electronic device for registering and calculating transactions. It is usually attached to a drawer for storing cash and other valuables. The cash register is also usually attached to a printer, that can print out receipts for record keeping purposes.

History

An early mechanical cash register was invented by James Ritty and John Birch following the American Civil War. James was the owner of a saloon in Dayton, Ohio, USA, and wanted to stop employees from pilfering his profits. The Ritty Model I was invented in 1879 after seeing a tool that counted the revolutions of the propeller on a steamship. With the help of James' brother John Ritty, they patented it in 1883. It was called Ritty's Incorruptible Cashier and it was invented for the purpose to stop cashiers of pilfering and eliminating employee theft or embezzlement.

Early mechanical registers were entirely mechanical, without receipts. The employee was required to ring up every transaction on the register, and when the total key was pushed, the drawer opened and a bell would ring, alerting the manager to a sale taking place. Those original machines were nothing but simple adding machines.

Ulmus 'Morton Plainsman' Vanguard

Ulmus 'Morton Plainsman' (selling name Vanguard™) is a hybrid cultivar raised by the Morton Arboretum from a crossing of the Siberian Elm U. pumila (female parent) and a specimen of the Japanese Elm U. davidiana var. japonica grown from openly-pollinated seed donated by the Agriculture Canada Research Station at Morden, Manitoba.

Description

Vanguard has modest upright growth, increasing in height by an average of 0.8 m in an assessment at U C Davis, with leaves much the same size and colour of the American Elm. However, its performance in the southern United States has not impressed, and it was dismissed, along with its Morton stablemates Commendation and Triumph, as "ugly" by Michael Dirr, Professor of Horticulture at the University of Georgia , on account of its "wild" growth and splaying branches.

Pests and diseases

Although resistant to Dutch elm disease, Vanguard remains very susceptible to pests such as the elm-leaf beetle Xanthogaleruca luteola , Japanese beetle, and cankerworms.

Vanguard (synthesizer)

Vanguard is a VSTi and AU software synthesizer by German independent publisher reFX.

Released in 2004, it is a virtual analog synthesizer with three oscillators, 32 waveforms, up to 10-times unison, a filter with a number of frequency responses, delay and reverb effects and stereo pattern controlled noise gate and arpeggiator, making this plugin useful among the electronic dance music producers. Most functions can be automated, such as cutoff frequencies, resonance, ADSR, and LFO. Vanguard works with any VST-capable host and features the Trancegate and Arpeggiator tools. The audio engine and a part of the factory sounds from Vanguard were programmed by Markus Krause from Tone2 Audiosoftware.

This synthesizer is used by many electronic dance music producers, however is not as prevalent as reFX's Nexus 2 ROM plugin. Nexus2 is so called because it replaced the upgraded 2007 package for Vanguard called "Nexus ROM" in early 2008.

Vanguard (journal)

Vanguard: A Libertarian Communist Journal was a monthly anarchist political and theoretical journal, based in New York City, published between April 1932 and July 1939, and edited by Samuel Weiner, among others.

Vanguard began as a project of the Vanguard Group, composed of members of the editorial collective of the Road to Freedom newspaper, as well as members of the Friends of Freedom group. Its initial subtitle was "An Anarchist Youth Publication", but changed to "A Libertarian Communist Journal " after issue 1.

Within several issues Vanguard would become a central sounding board for the international anarchist movement, including reports of developments during the Spanish Revolution as well as movement reports by Augustin Souchy and Emma Goldman.
