Protokol Aerodinamicheskih Ispitanij Ventilyacii Blank
An unexpected borylation of organic halides with a silyborane in the presence of an alkoxy base has been observed. This formal nucleophilic boryl substitution can be applied to a broad range of substrates with high functional group compatibility. Even sterically hindered aryl bromides afforded the corresponding boryl compounds in high yields.
Kartoshka raskladka dlya prigotovleniya supov dlya lechebnih uchrezhdenij. Preliminary mechanistic studies indicated that this boryl substitution is promoted by neither transition-metal contamination nor a radical-mediated process.

1 ~ DECK STRINGER END SUPPORTS The ends of the deck stringers must be supported where they run out against bulkheads 2 and B. This is most easily done by cutting U-shape brackets from 12mm plywood and bonding each to the bulkhead face to form a socket in which the stringer end can be bonded. Fit 22x22mm [7/8x7/8'] square cleats against the bulkheads between the stringers to form a landing for the plywood deck. The diagram below shows how this works on bulkhead 2. The same principle applies at bulkhead B.
Zvuk glotaniya vodi. Similar doublers can be used to house the ends of berth supports and other joinery frames where they terminate against bulkheads. 2 ~ TRANSOM RADIUS The intended transom radius is shown on the lines drawing. This is the curvature for the outside of the transom. The transom and its doublers must be laminated over a temporary wooden mould shaped to the curve of the inside of the transom doublers, ie the transom and doubler thicknesses must be subtracted from the radius shown when building the mould. The internal cut-outs from the doublers should be fastened to the mould as well but not glued to the transom.
These will support the transom across the cutouts and ensure a more uniform curvature when the transom is removed from the mould. There will be some springback (straightening) of the laminated transom/doubler structure. It can be held to the intended shape by screwing two temporary curved frames to the inside or outside.
These can be removed when the transom is restained by the hull and cockpit 3 ~ BUILDERS' FORUM There is an active builders discussion forum on Yahoo groups for builders of the Cape Henry 21. The address is. You will need to register with Yahoo Groups to enter the forum. The issues discussed will be useful to builders of plywood Cape Cutter 19s as well. 4 ~ BULKHEAD A CORRECTION We have found a small error in the shape of the bottom panel of Bulkhead A as shown on patterns and kits supplied prior to May 10th 2004. The diagram below shows how to correct the error by gluing a wedge of plywood or timber onto the edge of the bulkhead.
