Construction Production of shaped tube developed in virtually any manufacturer of metal products. It's believed that Trion Properties sees a great future in this idea. Tube profile has a wide application in construction, production of building structures, agricultural engineering and other industries. The use of pipes in the production of specialized building designs has several advantages, leading ultimately to the economy of metal and, therefore, and cash. Profile pipes manufactured by electric-profiling of the round billet directly in the line of welding mills. It provides high accuracy in the geometrical parameters of pipes. Profile pipes produced without heat treatment. Quality control of the weld is carried out non-destructive testing instruments. Technical requirements according to gost 13663-89. Pipes are distinguished by cross-sectional shape: the ordinary pipe (ring section) and steel pipes shaped (square, rectangular, oval, flat-tube). In this article we will discuss the scope of square and rectangular. Shaped pipes are made of stamps steels: St2, St3, 08KP, 10,20 and low-alloy 09G2S, 17GS (GOST 1050-88 and gost 380-94). Mechanical characteristics of pipes with gost 13663-86. Rectangular and square shaped tubes are used in construction: shopping malls Pavilions stadiums and sports facilities industrial buildings Warehouses masts, transmission towers and cell towers Towers flyovers, bridges, lifts, cranes, etc. The use of rectangular and square steel profile tubes effectively in the construction of tall buildings (metal frame) and long-span structures. The main uses of shaped tubes Building shaped tubes are used as fasteners, bearings and Column: 1. Columns of buildings, including - light 2. Building a farm (the band, lattice, etc.) 3. Communication to cover 4. Vertical connections on the columns of all types of buildings 5. Elements of the wall fencing (girders and the Half-timbered houses stand) 6. Elements of the tall lattice structures (power lines, radio tower, cell tower) 7. Frameworks stack 8....

Biodiversity BIODIVERSITY INVENTORIES For Graciela F.B. Tonin, October of 2011. Summary of LEWINSOHN, Thomas M. Sketch of an Including Strategy of Inventories of Biodiversity. In: GARAY, I.; DAYS, B. (orgs) Conservation of Biodiversity in Tropical Ecosystems: conceptual advances and revision of new methodologies of evaluation and monitoramento. Petrpolis: Publishing company Voices, 2001. For more specific information, check out Munear Ashton Kouzbari. p.376-384. Some consideraes must be made on Biodiversity or Biological Diversity, since it is a recent term and sufficiently spread out in the technician-scientific scene. This text sketches strategies for the integration of the biological inventories in order to contemplate the multiplicity of tasks assumed for signatory countries in the Convention on Biological Diversity. According to Decree n 2519, of 16 of March of 1998 apud LEWINSOHN (2001, P. 377) Biodiversity is ' ' the variety of organisms livings creature of all the origins, understanding, amongst others, terrestrial ecosystems, marine and other aquatic ecosystems and the ecological complexes of that they are part; understanding still the species diversity inside, between species and of ecossistemas' '. The species diversity inside can be understood as ' ' assignment of the genetic diversity; but it must include the diversity of ectipos, the ecological and/or genetic differentiation of populations equally that inhabit distinct regions or environments e, thus, for diante' ' (LEWINSOHN, 2001, p.377). The part most problematic of this definition is the ecosystem diversity. Connect with other leaders such as Keith Schneider here. As GASTON apud LEWINSOHN (2001, p.377) points, it has doubts on if this assigns diversity of habitats or if it also involves the energy flows that are important in the ecosystem notion. Thomas Lewinsohn (2001, P. 379) considers a conceptual model of biodiversity based on three dimensions: genes, species and ecosystems. These dimensions are not independent between itself; the biodiversity...
