Motor Car Racing

Motor car racing is a hobby that has been around since the invention of cars. Currently presents official statistics show more than 300 million followers scattered all over the world. The racing began its development in 1887 where he conducted the first steam-powered car race in history, the great evolutionary step came in 1906 where France was implemented and allowed the use of gasoline in cars from there the car racing was established as sport. After the implementation of gasoline league decided to create cars together, it was in Bordeaux France in 1946 where he finally believe to this day the most famous sport in terms of racing is concerned, the formula one. In 1956 the league changed its name cars together for what is now known as FIA (International Automobile Federation) and the racing was forced to name change because of its appeal worldwide.

The racing cars are divisions among the best known and most significant are: Rally: This is a race car competition with the unique ability to explore and overcome any obstacles that may arise on the road, these cars are designed to withstand the harshest blows and withstand weather extremes. Formula One: this is possibly the best-known division of motor racing, since it is the most promoted by all the world’s media, this car race in particular is focused on bringing the car speed limit in this competition wins the participant a certain number of turns in less time beating other competitors. Although this competition to show the world the most advanced race car technology, has a major drawback is the fragility that these cars should be treated. jeep Xtreme Racer: This is probably the mode newest race car, as soon as practice officially about 5 years, this is based on bringing a car with climbing features into a very high places or difficult access. This competition determines the winner by the time taken to reach this point, these cars are designed to grip and achieve the greatest possible force on land that a normal car would never arrive. Speed racer: This competition is based on bringing the car to even higher speed limits than the one with the unique formula that these cars are the only function is to accelerate, the development of this competition is usually in deserts and places which do not smoothly or rough terrain to the car reaches a peak performance. This race car is determined not by distance or time reached by car but by the overall speed at which to reach it.

Global Warming

About Global Warming Global warming is the term used to describe a gradual increase in the average temperature of the Earth s atmosphere and its oceans, a change that WILL permanently upset the Earth s CLIMATE FOREVER, – While many view the effects of global warming to be more substantial and more rapidly occurring than others do, the scientific consensus on climatic changes related to global warming is that the average temperature of the Earth has risen between 0.4 and 0.8 C over the past 100 years. The increased volumes of carbon dioxide and other greenhouse gases released by the burning of fossil fuels, land clearing, agriculture, and other human activities, are believed to be the primary sources of the global warming that has occurred over the past 50 years. Scientists from many parts of the world, – carrying out global warming research have recently predicted that average global temperatures could increase between 1.4 and 5.8 C by the year 2100. Changes resulting from global warming may include rising sea levels due to the melting of the polar ice caps, as well as an increase in occurrence and severity of storms and other severe weather events. Earth is naturally insulated by a delicate balance of heat-trapping (or greenhouse) gases in the atmosphere.

When the sun shines on the Earth, some of that heat is absorbed, keeping Earth warm enough to support life. The problem is that over the last century, we humans have been releasing more and more carbon dioxide and other heat-trapping gases into the atmosphere when we burn fuels and cut down forests. These additional gases have upset the natural balance of our atmosphere, trapping more heat than is healthy for the Earth. The result is human-caused global warming, which brings serious threats from increased flooding to the spread of disease to the disruption of agriculture in many parts of the world.

La Paz Safety

Eng. Mario Holguin the aftermath of Brasilia in 1998 there have been multiple order global, regional and national events. For my Brasilia was the inspirational spark that served as background for awakening interest in global road safety.Despite the growth of the vehicular field in the big Brazilian city, with the La Paz in the traffic campaign, there was a substantial decrease in traffic accidents and injuries for this cause.There was a political will and there was integration of the society for the implementation and enforcement of strong measures. There was magic.Even recalls welcome intervention in that sense of then President Fernando Henrique Cardoso. The 2000 report of the World Health Organization, the World Bank, the International Motorsports Foundation and other organizations, released two years later by the United Nations, constitutes the faithful and most important document that portrays the world reality of roads.The November 19 of 2003, adopted at the UN General Assembly, resolution 58/9 entitled Crisis on road safety in the Mundo.En that study settled clearly three fundamental aspects for the development of future work aimed to tackle this crisis.The first was to define a political will, where the globe Governments have the theme within your list of priorities.Secondly, recognize that traffic accidents are preventable. And third, that the participation of the associations and the private sector is essential to succeed in the struggle of accident prevention.

In April of the following year, at the World Health Day, the main agenda item was road safety. At that time approved the report of the Secretariat of the United Nations called road safety and Salud.Un interesting fact was that determined which are the vulnerable road users in our low and middle income countries, that fits today constitute a strong headache in Dominican Republic and in other Latin American Nations.Another momentous resolution of the General Assembly of the United Nations was approved the first of December 2005 with the name of improvement of road safety in the Mundo.Es when the need to implement programmes to preserve life young people on roads allowed. The celebration of the global road safety week for youth was defined in 2007 under the auspices of the Economic Commission of Europea.El World Congress of youth about the prevention of injuries due to accidents of transit in Geneva at the end of April 2007, it has served as a referential framework to develop national work in different parts.There was a significant statement in where youth assume commitments at different levels of society to reduce accidents on waterways.Finally, from the celebration of March 31 of this year, with the reading of a famous open letter to the United Nations signed by several personalities of worldwide influence, was convened at the headquarters of this agency in New York to 90 member countries to propose the holding of the Global Ministerial Conference on road safety sponsored by the Rusa.Esta Federation in 2009 motion was approved in Assembly by the United Nations about a month later. Efforts to eradicate the high rate of accidents on roads continue to develop. Everything is a process.

Global Warming

The population in communities currently lacks information on climate by what ignore the effects that can cause this on them if you have no foreknowledge of the actions of the climate and its changes rough that had in recent years due to massive contamination with greenhouse gases that have caused a desiquibrio between the factors and climatic elements. So the effects of the climate on Earth has claimed major disasters in agriculture livestock, infrastructure and a considerable number of human lives. Also known as climate change, global warming is considered as the land surface temperature increase, this is given as a result of the industrial evolution of man to produce their daily sustenance and the comforts that today has. Oil exploitation which gives rise to those fuels that move thousands of different engines for all machines, the combustion of these fuels have produced large amounts of smoke, which are dispersed in the atmosphere with a high content of carbon, productions whether the carbon dioxide (CO2) that altered ozone (O2) providing greater thickness of the layer. Also participate other gases such as SO2, NO2 and H2O and others more, these gases saturated the ozone layer allowing the Sun’s rays penetrate and produce heat at the Earth’s surface which is enclosed producing what today is known as the greenhouse effect. Global warming or climate change is the cause of the alteration of the climate by changing elements and factors that maintain the balance. The increase of storms, hurricanes, cold fronts, warm, stormy rains with electric shocks, poor distribution of rainfall; all this is the result of climate change.

Water is a substance formed by the oxidation of the hydrogen in the atmosphere, substance made up of two atoms of hydrogen and one of oxygen (H20). Water is regarded as the universal since it is a substance that through her solvent there are a myriad of reactions that allow the formation of different compounds chemicals. Water is the substance that allowed the life on Earth since she allows that there are chemical reactions in living things essential for survival. Water is the only substance that can exist naturally in three forms: liquid, solid and gaseous. There is no only air in the atmosphere, but there also water vapor which is colorless and odorless.

Atmospheric water represents less than 0.001% of the water of the Earth, but his role is very important for the climate. When we drink water, it is in liquid form, called State liquid; When we mascamos or bite an ice cube water is in solid state. The water can also be found in gaseous state this is represented in this way when its molecules are free-form, which is commonly known as water vapor. When liquid water in state change to vapour state, is known as evaporation. Condensation is the opposite. It is the process of transformation of steam to liquid water. After taking a bath, bathroom is filled with moisture or water vapor. The mist, hot, condenses on the cold bathroom, returning to its liquid state mirror: can see small droplets in the mirror.

Sustained Economic Development

It is impossible to sustain the economic development of a country using perpetual mechanisms of protection of domestic industry. The double substitution of imports – increased export levels requires organizations to fully refine their technological and management processes, which involves the proper management of all resources, including the technology, play a key role. Therefore, to achieve a true recovery of the Cuban company in the current context of the domestic market and for a successful position in the external environment is required, inter alia, a substantial increase in their innovation activities (Bejerano et Faloh al., 1997). As a means of achieving them emerges the so-called Business Process Improvement (PE), which is one of the critical lines of the economic boom that the country needs. General bases are a guide, as well as management tool for business organizations can, in an orderly, make the necessary changes in order to achieve maximum efficiency and effectiveness in its management.

The rules for the implementation and consolidation of this System State and Business Management Directorate (Decree No. 281/2007), highlights the importance of technological innovation, addressing in Chapter IX, the System of Innovation Management; however, the diagnostic tool that is part of the process, it appears that the activities are not covered or emphasized as specified. Although the country has a considerable scientific and technical potential, many times this is not properly used towards the development strategy that continues by outlining in very difficult conditions, so that it takes management processes at all levels leading to change in current ways of thinking and acting.

Antarctic Scientific Stations

The scientific research bases in Antarctica are using different technologies including thermal energy to continue their research. During the austral winter of 2006, 40 bases of 20 Nations operated in Antarctica and other 6 countries joined in the Antarctic summer. Thanks to the Antarctic Treaty practically all human activities, except a limited tourism and fishing, are reduced to scientific research, focused primarily on meteorology and climatology, though investigations due to the large number of bodies existing in this ecosystem has expanded. Almost the entire surface of the continent prevails the polar climate, where the average temperature of the warmest month does not exceed 0 C. Called climate of tundra, where the warmest month average exceeds 0 C, occurs only in the more northern coastal areas, as in the Antarctic Peninsula, adjacent and sub-Antarctic Islands. The average temperature in this region is – 17 Celsius. In midsummer, the days in Antarctica have light almost 24 hours a day, at midnight the Sun low to the horizon for then re-upload in a sinusoidal motion apparent, in the brief Antarctic summer hours when the Sun is closest to the horizon are called white nights, while during the long winter days remain in a prolonged darkness.

South of the Antarctic Circle there is at least one day that does not completely the Sun called the Solstice of summer and at least one night in which does not come out completely the Sun called the winter solstice. In the geographical South Pole day lasts for 6 months and the other 6 months night. This is due to the Earth’s rotation axis is tilted with respect to the plane of the orbit of the earth around the Sun. These scientific bases using all the technological advances to carry out their research in the field of the use of the thermal energy want to use direct sunlight in the summer months where Sun is shining almost 24 hours a day, but to take advantage of this thermal energy is important to have highly efficient equipment, some of these scientific bases have shown a great interest in equipment manufactured by a Canadian company called solarbeam, although in this country the weather is adverseThis company has managed to develop a system of solar concentration, which directs the whole solar energy to a focal point, is able to follow the Sun throughout the day thanks to a celestial algorithm and a GPS. This equipment is more efficient due to its system of double shaft that allows you that solar rays always fall perpendicularly to the team making a 262% more efficient than the flat solar panels. This type of renewable technologies is having a wide acceptance in the field of research and science aware how important it is to use energy sources that do not pollute the planet.

Take Scientific Method

The limestone crushing system in domestic cement plant often uses the two-stage crushing or one-stage crushing. The one-stage crushing system includes a dual-rotor impact breaker or a single-stage hammer crusher. With the emergence of the large-sized vertical shaft hammer crusher with excellent performance, many new and expanded enterprises chose the vertical impact breaker with good tightness, large crushing ratio and small particle size to improve the yield of the raw materials of the mill. In recent years, Henan Hongxing Mining Machinery has developed a new crushing equipment, namely cone crusher. The extrusion crushing is produced when the liner closes to the backplate. This kind of crusher has high crushing ratio. It has many advantages.

It has been widely used in many projects. In addition, many manufactures try to transform the crusher so that it can better adapt the production. In recent years, the power is sent to the vibrating exciter. The Inertial eccentric force produced by the vibrating exciter so that the crushing cone can be used as the secondary crushing equipment of the limestone. The materials enter the backplate and the crushing chamber with the frequent vibration and rotation. Learned from a cement plant in Hebei Province, at present, the concrete mixing plant has an immeasurable development prospect, so this plant is ready to take the cement concrete mixing plant as a new sales channel. We know that the cement and sand is very important for the concrete mixing plant. Therefore, in order to obtain greater profits, many cement plants began to cooperate in cement and sand.

They crush the abandoned limestone and basalt crusher sand maker or by, and then sell the final products with the cement, which will get more benefits.As the professional manufacturer of complete sets of mining machinery, such as cement production line, Henan Hongxing is always doing the best in products and service. It is reported that the river pebble, limestone and granite can be used as the main raw material of the gravel cogeneration. Especially for the river pebble, it is widely distributed in various regions of our country. Therefore, there are a lot of river pebbles production lines in our country. In April of this year, Hongxing Company provides a river pebble crushing system and a production line for a small gravel gravel enterprise in Urumqi, Xinjiang Province. This production line is mainly composed of the fine Jaw Crusher, Symons Cone Crusher, high efficiency Sand Making Machine, Sand Washing Machine, Vibrating Screen, and all the equipments are working in the centralized control.

Scientific Evolution

It is well known that at present, the scientific evolution has brought us great facilities and practical proposals and comfortable in our every day; artificial insemination, is no exception. This procedure is considered as one of the most important in the history of scientific advances since gives man to possibility of procreation. Artificial insemination is defined as a procedure that is used for those programs of assisted reproduction, as first choice for those couples who are sterile, i.e., that they have not achieved a pregnancy with the implementation of common procedures that have attempted to correct the factors affecting infertility. According to the State of those sterile couples, two types of procedures for artificial insemination may be considered: one where is used the sperm of the couple, and the one where some donor sperm is used. Anyone that is the case, should cautiously consider the woman’s menstrual cycle; Since you must deposit the respective semen, just when the egg is released during the period. In this same way, sperm in the uterus can be disposed of in a direct way; This depends on the status of patients who undergo this procedure.


Never losing of sight that the essential one is the formation of the pupils, the acquisition of abilities, values and attitudes. Using the adjusted available tools and more for determined activities. To the end, it will be concluded on the importance of computer science, over all in the education of pupils, as form of social inclusion. also, on the necessity of maintenance and application of resources in this level of education. To elaborate the text, one appealed journalistic article reading the educational, legislation and documents to it, books and articles.

Word-key: TICs; Learning; computer science; inclusion. 1. Introduction the objective of this article is to analyze as the use of the computer can assist the education process/learning. more, if can contribute to characterize the pupil and prepares it for the work market. The technological advances occurrences had in recent years practically compelled the education institutions to include in its programs of education, of some form, the use of computers and Internet. Being thus, the use of new technologies is a reality that appears in the schools and that it deserves to be argued. One of the great challenges for the educator is to help to become the significant information, to choose the truily important information between as many possibilities, to understand them of form each more including and deep time and to become them part of our referencial. (MORAN, 2000, p.23) For in such a way, they will be presented in the following work: ) the advantages of the use of the computer in the education process/learning; b) the diverse types of technologies that can be used in classroom.

Federal Prescription

Electronic forma bills of sale nothing more are of what a digital archive that is validated and receives during its emission validations (stamps) in digital format that they are the digital certificates. When emitting Electronic a Forma bill of sale we forget the risk that this procedure brings for the future fiscal controls. All Electronic Forma bill of sale when it is emitted receives an addend to its archive XML with data from the digital certificate of the sender and later it receives plus an addend to this archive with the data from the digital certificate from the Federal Prescription from Brazil validating the information and validating the commercial transaction. So that this type of procedure in them does not bring migraine, we must create a correct procedure of guard of these information that could be requested for the Treasury department up to 6 years after its emission. You are welcome it serves to keep the known archive as DANFE, that I eat the proper name says, ‘ ‘

Document of Assisting of Forma bill of sale Eletrnica’ ‘ , it only serves to give support to the transport of the merchandise and must be used for the transporter of the moment that leaves supplier of the merchandise and loses its purpose when the merchandise of the entrance in the deposit of the purchaser. You are welcome it serves in them also to print Electronic the Forma bill of sale, therefore in the paper the certificates validadores do not exist and the archive loses its legal value. The sent archive must be kept digitally and total complete, with the data of the operation, more the two (stamps) registers of the two demanded digital certificates in the operation, of the sender who validate of the data of archive XML and of the Treasury department that authorizes and validates to the operation. If it does not forget that this risk also exists for who is Electronic Forma bill of sale receiver, normally Electronic Forma bill of sale that our suppliers send in them and must be validated through the Federal Prescription of Brazil. The archive has that to be checked by the code of existing validation in Electronic the Forma bill of sale and later they will have to be kept digitally per 6 years in the same way that the emitted Electronic Forma bills of sale. Certain of that this article does not finish the subject and in the hope to have helped the people who still are in doubt, a great one I hug and until the next article where I will speak on as to proceed to validate Electronic a Forma bill of sale in the Federal Prescription and with this procedure to identify if Electronic a Forma bill of sale is false or true, until briefing.
