Whilst synthetic polymers have changed the world in many important ways, the negative impacts associated with these materials are becoming apparent in waste accumulation and microplastic pollution due to lack of biodegradability. Society has become aware of the need to replace or substitute environmentally persistent synthetic polymers, and cellulose has received a large amount of attention in this respect. The mechanical properties of cellulose, its renewable nature and biodegradability are advantageous properties. Drawbacks exist for the use of plant cellulose (PC), including the water footprint of cotton, deforestation associated with wood/dissolving pulp, and the extensive processing required to refine plants and wood into pure cellulose. Bacterial cellulose (BC), also known as microbial cellulose, is gaining momentum in both academic and industry settings as a potential solution to the many drawbacks of plant-based cellulose. Compared to PC, BC has high purity, crystallinity and degree of polymerisation, and can be manufactured from waste in a way that yields more cellulose per hectare, per annum, and requires less intense chemical processing. Native bacterial cellulose can be formed and shaped to an extent and is found in a variety of commercial products. However, dissolving and regenerating bacterial cellulose is a potential avenue to broaden the applications available to this material. The aim of this study is to review the applications which utilize regenerated bacterial cellulose, with a focus on the dissolution/regeneration methods used and discussing the associated limitations and future outlook.

E-commerce represents a rapidly growing share of consumer spending in the United States. We use transactions-level data on credit and debit cards from Visa, Inc. between 2007 and 2017 to quantify the resulting consumer surplus. We estimate e-commerce reached 8 percent of consumption by 2017, yielding the equivalent of a 1 percent boost to their consumption, or over $1,000 per household per year. While some of the gains arose from avoiding travel costs to local merchants, most of the gains stemmed from substituting to merchants available online but not locally. Higher income consumers gained more, as did consumers in more densely populated counties.

The treatment of benzyl 2,3-O-isopropylidene- - L -xylopyranoside with N-hydroxyphthalimide under Mitsunobu conditions, followed by protecting-group interchange, gave benzyl 4-O-[(tert-butoxycarbonyl)amino]-2,3- O-isopropylidene- - D -arabinoside. Mild acid hydrolysis and catalytic hydrogenolysis afforded 4-O-[(tert-butoxycarbonyl)amino]- D -arabinose that, upon heating in water, gave the dihydrooxazine [(4R,5S,6R)-5,6-dihydro-4,5-dihydroxy-6-hydroxymethyl-4H-1,2-oxazine] as a crystalline solid. A single-crystal structure determination of this solid showed it to exist in the 5 H 6 conformation. Reduction of the dihydrooxazine gave the tetrahydrooxazine [(4R,5S,6R)-4,5-dihydroxy-6-hydroxymethyl-3,4,5,6-tetrahydro-2H-1,2-oxazine]. The dihydrooxazine was an effective inhibitor of two -glucosidases (K i = 27 and 35 µM). Benzyl 2,3-O-isopropylidene- - L -xylopyranoside, via the derived imidazylate, was converted into a nitrile that, upon reduction and protecting-group manipulations, gave benzyl 4-C-aminomethyl-4-deoxy- - D -arabinoside. Treatment of this amine with hydrogen and palladium-on-carbon gave isofagomine.Key words: dihydrooxazine, tetrahydrooxazine, isofagomine, iminosugars, glycosidase inhibitors.

Church and state collide when England's king defies papal authority by seeking to divorce his wife, Katherine of Aragon. The consequences will be epochal for the country - and calamitous for the king's adviser, Cardinal Wolsey, who has been playing a dangerous game of his own. Passion, political intrigue and personal faith drive the action as Shakespeare brings vividly to life the thrilling human drama behind a pivotal moment in history. Filmed live at the Stratford Festival in Stratford, Canada in 2019.

A storm at sea brings love into the life of Pericles, Prince of Tyre; another snatches it away. This magical production of Shakespeare's epic tale follows a fairy-tale hero on a miraculous journey as fate guides the wandering hero to one of literature's most poignant reunions. Evan Buliung gives a sweeping performance, portraying the dashing young prince with verve and swagger, and taking him into his elder years with sorrowful tenderness. It is a story rarely told, and one you won't soon forget. Filmed live on stage at the Stratford Festival as part of the 2016 Stratford Festival HD Series. Audience Advisory: Addresses mature themes including the suggestion of incest without any on film depiction.

Working Paper No. 25610 E-Commerce represents a rapidly growing share of consumer spending in the U.S. We use transactions-level data on credit and debit cards from Visa, Inc. between 2007 and 2017 to quantify the resulting consumer surplus. We estimate that E-Commerce spending reached 8% of consumption by 2017, yielding consumers the equivalent of a 1% permanent boost to their consumption, or over $1,000 per household. While some of the gains arose from saving travel costs of buying from local merchants, most of the gains stemmed from substituting to online merchants. Higher income cardholders gained more, as did consumers in more densely populated counties.
