British NVC Community W17
NVC community W17 (''Quercus petraea - Betula pubescens - Dicranum majus'' woodland) is one of the woodland communities in the British National Vegetation Classification system. It is one of the six communities falling in the "mixed deciduous and oak/birch woodlands" group. This is a widely distributed community in northern and western Britain and represents mossy deciduous woodland of the uplands. There are four subcommunities. Community composition Two constant species are found in the tree canopy of this community: * Sessile oak (''Quercus petraea'') * Downy birch (''Betula pubescens'') Eight constant species are found in the field and ground layers of this community: * Wavy hair grass (''Deschampsia flexuosa'') * Greater fork-moss (''Dicranum majus'') * Glittering wood-moss (''Hylocomium splendens'') * Waved silk-moss (''Plagiothecium undulatum'') * Red-stemmed feather-moss (''Pleurozium schreberi'') * Bank haircap moss (''Polytrichum formosum'') * Little shaggy-moss (''Rhy ...

Hansa-Brandenburg W
The Hansa-Brandenburg W was a reconnaissance floatplane produced in Germany in 1914 to equip the Imperial German Navy. Similar in general layout to the Hansa-Brandenburg B.I landplane, the W was a conventional three-bay biplane with unstaggered wings of equal span. The pilot and observer sat in tandem, open cockpits, and the undercarriage consisted of twin pontoons. The NW and GNW of 1915 were a revised versions powered by a more powerful engine. Variants * W - initial production version with Benz Bz.II engine (27 built) * NW - revised version with Mercedes D.III engine * GNW - revised version with Mercedes D.III engine Operators ; *Kaiserliche Marine ; *Ottoman Air Force The Aviation Squadrons of the Ottoman Empire were military aviation units of the Ottoman Army and Navy.Edward J.

Mercedes-Benz 120
From 1931 to 1939, Daimler-Benz AG produced three cars ( Mercedes-Benz 130, 150 and 170 H) with rear engine as well as a few prototypes. The production numbers remained quite low for each of these models, especially compared to the production of classical front-engine Mercedes cars. Development and prototypes (W17/W25D) At the beginning of the 1930s, inspired by modern streamlined shapes, there were attempts to move car engines from the forward compartment to the rear of the car. Such a move allows a reduction in the volume of the front compartment. At the same time, the voluminous rear provides a lot of space above and behind the rear axle. Moreover, when engines are rear mounted, the drive shaft is eliminated. The most famous such development was with the 1930s Tatra cars under the leadership of Hans Ledwinka. In 1930, Daimler-Benz entrusted Hans Nibel with the development of a small rear-engined car, starting from the same principles. In 1931, working with Max Wagner, the typ ...

Snub Cube
In geometry, the snub cube, or snub cuboctahedron, is an Archimedean solid with 38 faces: 6 square (geometry), squares and 32 equilateral triangles. It has 60 edge (geometry), edges and 24 vertex (geometry), vertices. It is a chiral polytope, chiral polyhedron; that is, it has two distinct forms, which are mirror images (or "Chirality (mathematics), enantiomorphs") of each other. The union of both forms is a compound of two snub cubes, and the convex hull of both sets of vertices is a truncated cuboctahedron. Kepler first named it in Latin as cubus simus in 1619 in his Harmonices Mundi. H. S. M. Coxeter, noting it could be derived equally from the octahedron as the cube, called it snub cuboctahedron, with a vertical extended Schläfli symbol s \scriptstyle\begin 4 \\ 3 \end, and representing an Alternation (geometry), alternation of a truncated cuboctahedron, which has Schläfli symbol t \scriptstyle\begin 4 \\ 3 \end. Dimensions For a snub cube with edge length 1, its surface ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water-jugs-in-stand (hieroglyph)
The ancient Egyptian Water-jugs-in-stand hieroglyph, is Gardiner sign listed no. W17, W18, within the Gardiner signs for ''vessels of stone and earthenware.'' The hieroglyph is used as an ideogram in ''(kh)nt''-(ḫnt), for 'a stand (for vases)'. It is also used phonetically for (ḫnt). Egyptian "khenti" The ''water-jugs-in-stand hieroglyph'' is often written with the complement of three other hieroglyphs, the water ripple, N35, bread bun, X1, and ''two strokes'', Z4, to make the Egyptian language word foremost, ''khenti''. The complete composition block is: W17-N35:X1*Z4 As Egyptian "khenti",Budge, 1978, (1920). ''An Egyptian Hieroglyphic Dictionary'', 'khenti' , and other " 'Khenti'-Title-constructs", pp. 309-311. foremost is used extensively to refer to gods, often in charge of a region, or position, as ''foremost of xxxx''.

Watkins 17
The Watkins 17, also referred to as the W17, is an American trailerable sailboat that was designed by the Watkins brothers and first built in 1975. Production The design was built by Watkins Yachts in Clearwater, Florida, United States from 1975 to 1981, with over 100 examples completed. Production was curtailed in 1979, when the company was sold, with few boats built in 1979-1981. The design's moulds were eventually abandoned behind the old plant building when the company was wound up in 1989. The building was sold to an electrical contractor and the moulds are presumed to have been destroyed. Design The Watkins 17 is a recreational keelboat, built predominantly of hand-laid 24 oz rove fiberglass, with wood trim. The deck is a single piece of moulded fibreglass and the cockpit is self-bailing. It has a fractional sloop rig with aluminum spars made by Kenyan, a small, storage cuddy cabin, a spooned plumb stem, a vertical transom, a transom-hung rudder made from Philippine ...

Wesseler W 17
The Wesseler W 17 is an agricultural tractor made by H. Wesseler OHG. It is the firm's smallest two-cylinder model and was made from 1954 until 1956. In the Netherlands, the tractor was sold under the ''Vewema'' brand. Technical description The W 17 is based on a frameless design with the rear axle and front axle assembly directly flange-mounted to the engine. The rear axle is a ZF A-5/5 (or ZF A-5/6) transmission unit consisting of a portal axle and a constant-mesh gearbox with either five or six forward gears, and a regular reverse gear. The six-speed versions of the gearbox have an additional 1.5 km/h crawler gear below first gear, but are otherwise identical to the five-speed units, i.e. they have the same gearing and thus offer the exact same speeds. The transmission unit is designed for a maximum continuous input torque of and was available with a differential lock and a PTO. Since there is no drive shaft to the front axle, all W 17 tractors are rear- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Williams W-17 Stinger
The Williams W-17 Stinger is an American homebuilt aircraft, homebuilt racing aircraft that was designed for Formula One Air Racing by Art Williams and produced by his company, Williams Aircraft Design of Northridge, California, introduced in 1971. The aircraft was at one time available in the form of plans for amateur construction, but only one was ever constructed.Plane and Pilot: ''1978 Aircraft Directory'', page 160. Werner & Werner Corp, Santa Monica CA, 1977. Design and development The W-17 Stinger features a cantilever mid-wing, a single-seat enclosed cockpit under a bubble canopy, fixed conventional landing gear and a single engine in tractor configuration. The aircraft fuselage is made from sheet aluminum in a monocoque structure. The wings are all-wood, with laminated spruce spar (aviation), spars. Its span wing employs a NACA airfoil, NACA 64008 airfoil at the wing root, transitioning to a NACA airfoil, NACA 64010 at the wing tip. As the Formula One rules require, ...
