Knurling knurling is the process by which, the wire rod passes through a series of rollers until the steel rod that is sought, besides providing him with a corrugated allows the product thus produced can have good adhesion to the concrete as the main application This product is the construction area better known as steel rods. Because the lives of people depend on these steel rods always standardized by national standards, but without, you can use the ANSI or European standards UNE 36 068. The steel rods they can be obtained in a variety of sizes ranging from growing numbers 6-40 mm, equivalent to the section in square centimeters, how to acquire them is the weight can speak of "Iron quintals" although the appropriateness Kg Steel would this when it comes to rods if the product is steel columns or beams prefabricated sections talk about specific units as well as long in advance by the client when the diameter exceeds 1.6 cm long is acquired in Steel Bars, although not usual for these sections indented, but if the diameter is less than this dimension can be found in rolls or coils steel structural calculations to ensure these steel bars must meet minimum requirements to provide the following points: Manufacturer ID test to identify load and elongation at break according to the relevant national standards defined Yield perfectly simple bending adhesion test and folded and unfolded according to specific standard corrugated Features Section Average manufacture begins with the receipt of the billet square section, which is comprised of several rolls that give you a round or oval and generate corrugated end of the process is performed after the respective cooling, which must be done carefully to ensure the homogenization of mechanical properties throughout manufactured item. The composition of the rolling elements is usually associated with the high carbon steels 0.80% as the billet, comes from a casting of these features obtained from a blast furnace, however, if the process is the reduction in an electric oven can get better quality laminates, malleable and less brittle, since when the percentage decreases coal decreases the fragility and hardness and also giving space to the ductility and machinability. The components can be found in such materials are not only coal and iron, we can identify silicon, manganese, phosphorus, sulfur, aluminum, chromium, titanium, vanadium, molybdenum, nickel, tin, etc being the predominant manganese with approximately 0.30% and phosphorus to 0.48% with a milled edge geometry usually consists of transverse ribs to the main axis of the steel rods but typically found indented steel rods in the form of the letter X and even with projections in the form of points, geometry no longer in use, the rods produced by the method of silk are often referred to as rods or rods corugadas with projections.
In 2006 it launched An Inconvenient Truth (an Inconvenient Truth). A set of documents that approaches the heating global, and the climatic changes for the world. Devoting itself winning of the Set of documents Oscar better in the year of 2007.
Al Gore is an ecological activista that wrote two books: The land in rocking (Ecology and the Human Spirit? 1993) and an Inconvenient Truth? 2006. In 2007 it still received the Prize Nobel from the Peace, receiving in the same year the Prize Prince of woollen Asturias Concord. 3-SUMMARY OF the WORKMANSHIP: The set of documents brings a vision of the current condition of the planet where Al author Gore displays of form clear and based on statisticians the real situation of the layer atmospheric, or better, of the proper planet land. The author goes alternating situations of its proper life amongst them the accident suffered for its son when this had only 06 years, this accident that almost vitimou its son stimulated it to travel and to understand the problems suffered for the land better. Also displaying the problems climatic of some countries as Argentina, Italy and Imalaia, the documentary one calls the attention for the fact from that 40% of the people in the world receive drinking waters of the systems rivers and sources that are fed for more than the half of the melting of glaciers, and inside of 40 years these people will face water scarcity. Al Gore affirms that the social evolution as well as the population growth of certain form contributes for the occured climatic changes in the whole world, bringing through the set of documents a statistics of that in 50 years the population increased of 2,3 billion (1945) for 6,4 billion (2005) and the forecast for the year of 2050 is of 9,1 billion.
Other ways that act as educative agents and amongst them exist many are new technologies, that receive emphasis in this process due its pedagogical power and influence that exert in general on the society. Thus, the reflection on the ways for which if they have introduced and used in the schools the new technologies of communication and information, is based on the concept of that To make a pedagogical reading of the medias is to verify the scienter of the communicative processes (of nature politics, ethics, psychological and didactic) gifts in the new technologies of communication and of the information and in the forms of metodolgica and organizativa intervention. (LIBNEO, 2000, P. 58) the understanding. Sarah White will not settle for partial explanations.
Becomes necessary of that the integration of these technologies is not more simply an option: they are day to day part of each pupil and therefore they must serve of complement and support for the professor in its interaction with the students. Ahead this reality the professionals of the education area need to have some knowledge on the use of these technologies, therefore when being inserted in ‘ ‘ it was of informtica’ ‘ , the domain of the code of language will allow the technological them to interact with the world in more critical, reflexiva and participativa way. Such phenomenon demands a professional qualification that helps the professor to face the new challenges that will appear and ‘ ‘ for this one becomes necessary to prepare the professor pedagogically to use the technologies in the formation of citizens who will have to produce and to interpret the new languages of the current world and futuro’ ‘ (Sampaio, 1999, P. 15). When perceiving to how much the technologies have been part of the daily one of the pupils, the necessary school to present an education directed to the qualification of these in dealing with this technological advance.
Now, you, already as a success entrepreneur, need to have a continuous plan of accompaniment and evaluation, so that she makes the necessary adjustments and adequacies. Of this form, you he will be capable of: to know well and to extend its business; to invest in other equipment; to divulge its mark; to contract more employed; to get greaters profits; to identify chances; to obtain financing; to communicate with partners and suppliers. 3.Tipos of Benchmarking In the enterprise scope are possible to detach some types of benchmarking, these can be; – lnterno – Competitive – Generic – Functional – Internal Benchmarking; it can inside be made of the proper company, where each session can search references in the other sessions of work, searching the improvement of the executed tasks. Jeremy Kidd shines more light on the discussion. – Competitive Benchmarking; the company focuses another company who disputes the same market directly, or either, a company whom she manufactures or vende the same type of merchandise or gives type of service the same. For this it is necessary to observe you so easily practise them of the other company, however no direct accepted competitor that its information are divulged so that can favor and give competitive advantages for the other organization. – Functional Benchmarking; he is not dedicated to the direct competitor, but yes to the other organizations that more possess a model of production or attendance to the customer with sophisticated techniques than they can take care of and come to improve the process of the company who is effecting the research. – Generic Benchmarking; it has the characteristic to search the best processes between that they interest and they satisfy the yearnings of the company, this process is more complex, however the quality index is superior to the others and has the capacity to generate one high return in long stated period for the organization. 4. Difficulties and problems in the implantation and performance of the Benchmarking the Benchmarking is a management process that it makes possible the improvement of the enterprise activities of continuous form, adding values to the same one.
