Aging of whiskey spirits in barrels of non-traditional volume
ABSTRACTAGING OF WHISKEY SPIRITS IN BARRELS OF NON-TRADITIONAL VOLUMEByJohn D.E. Jeffery In the aging of whiskey spirits, oak barrels provide vessels for containment which are semi-permeable to the spirit and to outside air. The barrel wood itself provides extractives derived from structural …

Investigation of Substrate Specificity in Phosphate Binding Barrels and Mechanistic Studies of Orotidine Monophosphate Decarboxylase
"Orotidine 5'-monophosphate decarboxylase from Methanobacterium thermoautotrophicum (MtOMPDC) catalyzes the decarboxylation of orotidine 5'-monophosphate (OMP) and uridine 5'-monophosphate (UMP) with an enormous rate acceleration, 1.8 x 1016 (kcat = 5 s-1, 25°C; knon = 2.8 x 1016 s-1), and …

Bad Apples, Bad Barrels, and the Structure of Marketing Channel Relationships: Analyses of the Propensity for Opportunism and Opportunistic Behaviors
The theoretical frameworks of transaction cost economics and agency theory are widely used to design appropriate governance structure for constraining opportunism within marketing channels. These approaches generally assume that marketing channel managers are opportunistic, and only economic …

Evolution of (Beta/alpha)8 Barrels: Refinement of Enzymatic Efficiency for a New Ortho-Succinylbenzoate Synthase (Osbs) From a Promiscuous Progenitor
This work allowed a step-wise pathway of changing base pairs to be elucidated that illustrates that a minimal amount of mutations (four from wild-type to I19F/R24W/D297G) are necessary to develop a new function. Additionally, the "new" function of OSBS activity was achieved with changes to …

Estudio de técnicas de higienización mediante proyección de dióxido de carbono y renovación aromática mediante inserción de duelillas en barricas usadas
… only possible response is the use of oak barrels in the ageing of their wine or alternative systems with oak wood adition. Classic alternatives for oak aging without barrels are oak staves into stainless-steel container or oak fragments into a mesh submerged in wine. Frequently, those …

Gauging a State: Excise Taxation, Practical Mathematics, and Cask Measuring in Seventeenth Century England
… designed to calculate the contents of wooden barrels for the purposes of collecting excise revenue for the English state. This research situates the work of mathematical practitioners alongside the practices of excise officers, or gaugers, to examine how the calculation of the contents of …

A new technology for imparting oak character to wine: application to a New Zealand chardonnay wine
… wine under different conditions. New French oak barrels are the preferred ageing containers by the winemakers at Morton Estate Winery; especially those from Seguin Moreau and Dargaud & Jaegle. New French oak releases extractable compounds at a rate which is considered desirable. Wines which were …

The Economic Water Model - a method and software program for assessing the impacts of storm water "green solutions" in urban areas
… such as rain gardens, bioswales, and rain barrels. Estimating average annual runoff at the property level is essential to providing precise estimates on the effectiveness of stormwater “green solutionsâ€� like rain barrels and rain gardens. This information can also be used to implement a …

Brewery Design and Experimentation
… with production capacities of 300, 800, and 3000 barrels per day. A base case is presented with alternative cases for consideration. Further analysis of the effects of malt addition, hops addition, and fermentation temperature on the alcohol production and acidity are presented through the use of …

A Review of Alternatives to Injection of Petroleum Wastewater from Oil and Gas Extraction
… consumption and production up to 107 million barrels of crude oil per day; the negative environmental impact and freshwater dearth can also be expected to progressively worsen as petroleum refinery wastewater increases to between 42.8 – 171.2 million barrels per day. While regulatory …

Effect of Leaching Scale on Prediction of Total Dissolved Solids Release from Coal Mine Spoils and Refuse
… (~1.5 m³) with run-of-mine material and into barrels (~0.1 m³; screened to ≤ 15 cm) under natural field environmental and leaching conditions. Similarly, two coarse coal refuse samples were placed into lab columns and field barrels. Comparative results suggest the column method was a …

Snapshots of radical enzyme catalysis : the crystal structures of biotin synthase and lysine 5,6-aminomutase
… adheres to the general theme of barrels or barrel-like structures for enzymes that utilize 5'-deoxyadenosyl radicals in catalysis. Additionally, the structure of lysine-5,6-aminomutase implicates pyridoxal phosphate in a novel role, acting as a lock to prevent the formation of …

Age-Dependent Effects Of Chronic GABAA Receptor Blockade In Barrel Cortex
… binding is transiently increased in rat whisker barrels during the second postnatal week, at a time when neurons in the developing rat cortex are vulnerable to excitotoxic effects. To test whether these GABAA receptors might serve to protect neurons from excessive excitatory input, polymer …

Hydrocarbon Potential of Ne Libya (Cyrenaica): Sedimentology, Seismic Interpretation and Petroleum System Study
… NE Libya, a country that produces 1.74 million barrels of oil a day. Today Libya’s productive sedimentary basins include the Sirt, Ghadamis, Murzuq, and Tripolitania basins that collectively contain the country’s major 320 producing oil fields whose reserves exceed 44 billion barrels of …
