List Of Islands In The Houtman Abrolhos
The Houtman Abrolhos is an island chain off the west coast of Australia. It is widely reported that the Houtman Abrolhos contains 122 islands, but only 93 islands had gazetted names in 1996. In the gazetteer of 2011 Hartley Island appears no more, but Barge Rock, Second Sister and Shag Rock appear, which raises the number of gazetted names to 96 (30 in the Wallabi Group, 38 in the Pelsaert Group and 28 in the Easter Group). In addition to the gazetted islands, six island groups have been gazetted. The three main groups are the Wallabi Group, the Easter Group and the Pelsaert Group. In addition, the Easter Group contains a group known as the Eastern Islands, and the Pelsaert group contains groups known as the Mangrove Group and the Numbered Islands.

Dakin Building
The Dakin Building is an architectural award-winning class A office building on the San Francisco Bay in Brisbane, California. Serving as a corporate headquarters building for several companies of national prominence, it was built from the profits of the Garfield character whose licensed products of the R. Dakin Company division of Applause Toys soared in sales in the late 1980s. Located on Sierra Point, it became a landmark in the San Francisco Bay Area for its distinctive design and was nicknamed the Luke Skywalker building for its dramatic posture overlooking the bay, in contrast to a neighboring office building with a dark, ominous appearance that was nicknamed the Darth Vader building. Ownership and history The Dakin Building was constructed in 1986 under commission of the R. Dakin Company, one of the largest manufacturers of plush products (mainly teddy bears) in the United States at that time. Dakin was in a large upswing of sales and profits in the late 1980s fueled by s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dakin's Solution
Dakin's solution is a dilute solution of sodium hypochlorite (0.4% to 0.5%) and other stabilizing ingredients, traditionally used as an antiseptic, e.g. to cleanse wounds in order to prevent infection.Jeffrey M. Levine (2013): "Dakin’s Solution: Past, Present, and Future". ''Advances in Skin & Wound Care: The Journal for Prevention and Healing'', volume 26, issue 9, pp. 410–414. The preparation was for a time called also Carrel–Dakin solution or Carrel–Dakin fluid. Use Carrel and Dakin used a variety of apparatuses to infuse the solution continuously over the wounds. In modern typical usage, the solution is applied to the wound once daily for lightly to moderately exudative wounds, and twice daily for heavily exudative wounds or highly contaminated wounds.Century Pharmaceuticals, Inc.:Dakin's solution FAQ. Accessed 2018-06-14. The healthy skin surrounding the wound should preferably be protected with a moisture barrier ointment (e.g., petroleum jelly) or skin sealant as ...

Dakin Reaction
The Dakin oxidation (or Dakin reaction) is an organic redox reaction in which an '' ortho''- or ''para''-hydroxylated phenyl aldehyde (2-hydroxybenzaldehyde or 4-hydroxybenzaldehyde) or ketone reacts with hydrogen peroxide in base to form a benzenediol and a carboxylate. Overall, the carbonyl group is oxidized, and the hydrogen peroxide is reduced. The Dakin oxidation, which is closely related to the Baeyer–Villiger oxidation, is not to be confused with the Dakin–West reaction, though both are named after Henry Drysdale Dakin. Reaction mechanism The Dakin oxidation starts with nucleophilic addition of a hydroperoxide anion to the carbonyl carbon, forming a tetrahedral intermediate (2). The intermediate collapses, causing ,2aryl migration, hydroxide elimination, and formation of a phenyl ester (3). The phenyl ester is subsequently hydrolyzed: nucleophilic addition of hydroxide from solution to the ester carbonyl carbon forms a second tetrahedral intermediate (4), which ...
