the extreme ice survey eis , based in boulder, colorado, uses time-lapse photography, conventional photography and video to document the effects of global warming on glacial ice. it is the most wide-ranging glacier study ever conducted using ground-based, real-time photography.
carbon fibers or carbon fibres alternatively cf, graphite fiber or graphite fibre are fibers about 5–10 micrometres in diameter and composed mostly of carbon atoms. carbon fibers have several advantages including high stiffness, high tensile strength, low weight, high chemical resistance, high temperature tolerance and low thermal expansion.
one benefit of clinching is the capability to join prepainted sheet metal commonly used in the appliance industry without damaging the painted surface. clinching is an important means of fastening aluminum panels, such as hoods and decklids, in the automotive industry, due to the difficulty of spot welding of aluminum.
carbon fibre-reinforced silicon carbide c/sic is a development of pure carbon–carbon, and can be used in automotive applications, such as components of brake systems on high performance road cars, namely the brake disc and brake pads. c/sic utilises silicon carbide with carbon fibre, and this compound is thought to be more durable than pure carbon-carbon.
a sandwich panel is any structure made of three layers: a low-density core, and a thin skin-layer bonded to each side. sandwich panels are used in applications where a combination of high structural rigidity and low weight is required. the structural functionality of a sandwich panel is similar the classic i-beam, where two face sheets primarily resist the in-plane and lateral bending loads, while the core material mainly resists the shear loads. the idea is to use a light/soft but thick layer f
the panels are lightweight and very robust. they are especially suited for similar structure projects and low-cost, mass housing schemes. to get an added layer of protection against destructive weather, galvanized roofs will help by eliminating the risk of corrosion and rust. these types of modular enclosures can have load-bearing roofs to .

dyneema composite fabric, former known as cuben fiber, is a high-performance non-woven composite material used in high-strength, low-weight applications. it is constructed from a thin sheet of uhmwpe laminated between two sheets of pet or bopet. it is used in various applications that call for a fabric with high tensile strength, but where low weight is desirable, such as sails and ultralight backpacking equipment. the material was developed by the cuben fiber and cubic tech corporations in the
radiation-absorbent material, usually known as ram, is a material which has been specially designed and shaped to absorb incident rf radiation also known as non-ionising radiation , as effectively as possible, from as many incident directions as possible.the more effective the ram, the lower the resulting level of reflected rf radiation. many measurements in electromagnetic compatibility emc .
calcium sulfate or calcium sulphate is the inorganic compound with the formula caso 4 and related hydrates.in the form of γ-anhydrite the anhydrous form , it is used as a desiccant.one particular hydrate is better known as plaster of paris, and another occurs naturally as the mineral gypsum.it has many uses in industry. all forms are white solids that are poorly soluble in water.
calico is a plain-woven textile made from unbleached and often not fully processed cotton. it may contain unseparated husk parts, for example. the fabric is far less fine than muslin, but less coarse and thick than canvas or denim. however, it is still very cheap owing to its unfinished and undyed appearance. the fabric was originally from the city of calicut in southwestern india. it was made by the traditional weavers called cāliyans. the seven trust fabric was dyed and printed in bright hues .
standard roughness rz increases with the sheet thickness, but decreases with laser power and cutting speed. when cutting low carbon steel with laser power of 800 w, standard roughness rz is 10 μm for sheet thickness of 1 mm, 20 μm for 3 mm, and 25 μm for 6 mm.
solar water heating swh is the conversion of sunlight into heat for water heating using a solar thermal collector.a variety of configurations is available at varying cost to provide solutions in different climates and latitudes. swhs are widely used for residential and some industrial applications.
calcite can be either dissolved by groundwater or precipitated by groundwater, depending on several factors including the water temperature, ph, and dissolved ion concentrations. although calcite is fairly insoluble in cold water, acidity can cause dissolution of calcite and release of carbon dioxide gas.
they surround a large area metal sheet absorber with high vacuum inside a flat envelope made of glass and metal. they offer the highest energy conversion efficiency of any non-concentrating solar thermal collector, but require sophisticated technology for manufacturing. they should not be confused with flat plate collectors featuring low vacuum .
corrugated galvanised iron or steel colloquially corrugated iron near universal , wriggly tin taken from uk military slang , pailing in caribbean english , corrugated sheet metal in north america and occasionally abbreviated cgi is a building material composed of sheets of hot-dip galvanised mild steel, cold-rolled to produce a linear corrugated pattern in them.
dual-phase steel dp steel is a high-strength steel that has a ferritic–martensitic microstructure. dp steels are produced from low or medium carbon steels that are quenched from a temperature above a 1 but below a 3 determined from continuous cooling transformation diagram.
fundamental limit on specific strength. the null energy condition places a fundamental limit on the specific strength of any material. the specific strength is bounded to be no greater than c 2 9 × 10 13 kn·m/kg, where c is the speed of light.
the bentley continental gt is a grand tourer manufactured and marketed by british automaker bentley motors since 2003. it was the first car released by bentley under volkswagen ag management, after the company's acquisition in 1998, and the first bentley to employ mass production manufacturing techniques.
graphite / ˈ ɡ r æ f aɪ t / , archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure.it occurs naturally in this form and is the most stable form of carbon under standard conditions.under high pressures and temperatures it converts to diamond.graphite is used in pencils and lubricants.

a subdivision of the sheet plywood boat building method is known as the stitch-and-glue method, where pre-shaped panels of plywood are dn together then edge glued and reinforced with fibreglass without the use of a frame. metal or plastic ties, nylon fishing line or copper wires pull curved flat panels into three-dimensional curved shapes.
sheets of eps are commonly packaged as rigid panels common in europe is a size of 100cmx50cm, usually depending on an intended type of connection and glue techniques, it is in fact 99.5cmx49.5 cm or 98cmx48cm; less common is 120x60cm ; size 4 by 8 or 2 by 8 feet in the united states . common thicknesses are from 10mm to 500mm. many .
