The diketene acetal 3,9-diethylidene-2,4,8,10-tetraoxaspiro [5.5]undecane, DETOSU, is a reactive bifunctional monomer that forms biodegradable polyorthoesters by polyaddition with α,ω-diols . Polyorthoesters are used as embedding media for pharmaceuticals in extended release formulations for controlled drug release by surface erosion under ...
3,9-Divinyl-2,4,8,10-tetraoxaspiro [5.5]undecane ( DVTOSU) is a bicyclic organic molecule having a central quaternary carbon atom (a spiro atom) with which two alicyclic rings are linked, each comprising five atoms. DVTOSU is a diallyl acetal and the precursor for the isomeric ketene acetal monomer 3,9-diethylidene-2,4,8,10-tetraoxaspiro [5.5]undecane (DETOSU) which is a building block for ...

In Europe, 2-8-4 tender locomotives were designed mainly for passenger express trains, but they also hauled long distance express freights to increase utilisation. European 2-8-4 tank locomotives were a logical transition from the 2-8-2T locomotive types, allowing larger fireboxes and larger coal bunkers.
For example, from the table for modulus 15 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 (residues in bold ). The product of the nonresidues 2 and 8 is the residue 1, whereas the product of the nonresidues 2 and 7 is the nonresidue 14.
The first 4-8-2 in Australia was the 3 ft 6 in ( 1,067 mm) gauge Q class of the Tasmanian Government Railways. Nineteen were built in batches between 1922 and 1945 by Perry Engineering in South Australia, Walkers Limited of Maryborough, Queensland and Clyde Engineering of New South Wales.
(Reuters) -Eli Lilly agreed to buy Morphic Holding for $3.2 billion in cash, the companies said on Monday, beefing up its portfolio of inflammatory bowel disease (IBD) drugs and expanding its ...
A 2-8-8-4 steam locomotive, under the Whyte notation, has two leading wheels, two sets of eight driving wheels, and a four-wheel trailing truck. The type was generally named the Yellowstone, a name given it by the first owner, the Northern Pacific Railway, whose lines ran near Yellowstone National Park. Seventy-two Yellowstone-type locomotives ...
