Question: Bragdy Nant produces an unpasteurised beer without additional what?
Context: The Thomas Aquinas Dictionary is a collection of quotations by medieval philosopher and theologian Thomas Aquinas, indexed by keywords contained within the quotations.  Most of the quotations are taken from the "Summa Theologica", with additional material from the "Summa contra Gentiles".  The quotations are listed without additional commentary or explanatory notes, although the volume does contain an introduction to the work of Thomas Aquinas written by Theodore E. James.  Scholarly reviews were critical of the work when it was published, particularly in terms of the selection and arrangement of material.  The book does, however, still appear in bibliographies of reference material on Thomas Aquinas. The brasserie Lancelot is a French brewery founded in 1990 by Bernard Lancelot, located on the site of a gold mine in Roc-Saint-André in Morbihan.  It produces seven top-fermented, unfiltered, naturally-produced and unpasteurised beers, named after figures from the history and literature of Brittany.  It is one of the main brewery in the west part of France with a production of 30 000 hectoliters per year.  It is the number one local beer in Brittany on-trade and number two off trade. Working memory training is intended to improve a person's working memory.  Working memory is a central intellectual faculty, linked to IQ, ageing, and mental health.  It has been claimed that working memory training programs are effective means, not only for treating attention-deficit/hyperactivity disorder (ADHD) and other cognitive disorders, but to improve intelligence and to enhance cognitive functioning in typically developing children and healthy adults.  23 studies with 30 group comparisons, show that clinical memory training programs produce reliable short-term improvements in working memory skills in children and adults with ADHD.  Yet, the study results differ with regard to conclusive evidence that such effects can be maintained long-term without additional follow-up training.  There is also no convincing evidence of the effect of working memory training to other skills such as nonverbal and verbal ability, inhibitory processes in attention, word decoding, and arithmetic.  While most studies show clinical relevance of working memory training programs for ADHD population, they cast doubt that these program should be considered as methods of enhancing cognitive functioning in children and adults without working memory deficiencies. Low-alcohol beer (also called light beer, non-alcoholic beer, small beer, small ale, or near-beer) is beer with low alcohol content or no alcohol, which aims to reproduce the taste of beer without the inebriating effects of standard alcoholic brews.  Most low-alcohol beers are lagers, but there are some low-alcohol ales. An allonge (from French "allonger", "to draw out") is a slip of paper affixed to a negotiable instrument, as a bill of exchange, for the purpose of receiving additional endorsements for which there may not be sufficient space on the bill itself.  An endorsement written on the allonge is deemed to be written on the bill itself.  An allonge is more usually met with in those countries where the Code Napoleon is in force, as the code requires every endorsement to express the consideration.  Under English law, as the simple signature of the endorser on the bill, without additional words, is sufficient to operate as a negotiation, an allonge is seldom necessary. HM Advocate v Ross was a 1991 Scots criminal law case decided by the High Court of Justiciary.  The defendant had been charged with violently attacking others in a public house, but was allowed to go free on the premise that he was in a state of non-self-induced automatism.  Others in the bar had slipped LSD and other drugs into his beer without him knowing, and there was only a small amount of alcohol he had been drinking so he was not responsible for his intoxication which led to the violent actions. Damage mechanics is concerned with the representation, or modeling, of damage of materials that is suitable for making engineering predictions about the initiation, propagation, and fracture of materials without resorting to a microscopic description that would be too complex for practical engineering analysis.  Damage mechanics illustrates the typical engineering approach to model complex phenomena.  To quote Dusan Krajcinovic, "It is often argued that the ultimate task of engineering research is to provide not so much a better insight into the examined phenomenon but to supply a rational predictive tool applicable in design".  Damage mechanics is a topic of applied mechanics that relies heavily on continuum mechanics.  Most of the work on damage mechanics uses state variables to represent the "effects" of damage on the stiffness and remaining life of the material that is damaging as a result of thermomechanical load and ageing.  The state variables may be measurable, e.g., crack density, or inferred from the "effect" they have on some macroscopic property, such as stiffness, coefficient of thermal expansion, remaining life, etc.  The state variables have conjugate thermodynamic forces that motivate further damage.  Initially the material is pristine, or "intact".  A damage activation criterion is needed to predict damage initiation.  Damage evolution does not progresses spontaneously after initiation, thus requiring a damage evolution model.  In plasticity like formulations, the damage evolution is controlled by a hardening function but this requires additional phenomenological parameters that must be found through experimentation, which is expensive, time consuming, and virtually no one does.  On the other hand, micromechanics of damage formulations are able to predict both damage initiation and evolution without additional material properties. Bragdy Nant is an ale brewery near the town of Llanrwst, North Wales.  The brewery produces cask and bottle-conditioned ales, and is one of four North Wales breweries jointly operating the Albion Ale House in the town of Conwy.  The name Bragdy Nant is Welsh for "River" or "Stream Brewery". Cask ale or cask-conditioned beer is unfiltered and unpasteurised beer which is conditioned (including secondary fermentation) and served from a cask without additional nitrogen or carbon dioxide pressure.  Cask ale is also sometimes referred to as real ale in the United Kingdom, a term coined by the Campaign for Real Ale, often now extended to cover bottle-conditioned beer as well. An Interexchange Carrier (IXC) is a U.S. legal and regulatory term for a telecommunications company, commonly called a long-distance telephone company, such as MCI (before its absorption by Verizon), Sprint and the former AT&T Corporation (before its merger with SBC in 2005).  In the United States, it is defined as any carrier that provides inter-LATA communication, where a LATA is a local access and transport area.  From the telephone user's point of view, the long-distance company does not handle calls that do not have additional tolls.  Calls made across phone circuits within the local geographic area covered by one local network are handled only by that one LATA, commonly called a 'local telephone exchange.'  Local calls are usually defined by connections made without additional charge whether the connected call is in the same LATA or connects to another LATA with no charge.  In the United States intraLATA usually refers to rated or 'Toll' calls between LATA within state boundaries, as opposed to interstate, or calls between LATA in different states.
