Arup will be engineering that provides the technology for this project last December 2 Qatar was selected by FIFA as the future site of the 2022 World Cup. The challenge now is to demonstrate to the world how advanced technology can cope with adverse temperatures for the practice of football. With a population of just over one million inhabitants and the promise of filling 50,000 seater stadiums, Qatar is a country with little football history. But that has not been a difficulty for the candidacy. The worst thing has been to overcome the problem of temperature in summer, which can reach 50 degrees Celsius.
To respond to these climatic challenges the candidacy riyal had services of Arup international engineering, who was in charge of designing a prototype of latest generation Stadium. The prototype, which was taught to the completely finished FIFA last September, consists of a pilot 500 seater stadium capable of creating a controlled microclimate, both on the football field and in the stands and the rest of public spaces. A solar Orchard next to the stadium generates electricity and hot water to high temperature, which then becomes cold to weatherize the play space. As a stadium usage profile corresponds to a very high energy demand during a short period of time, the cold generated by solar panels is stored underneath the stadium several hours before the event, then it downloaded during the game. The solar Orchard, however, will operate throughout the year, exporting electricity to the public network when the stadium is not in use. The sizing of the solar Park ensures that the energy generated during the year exceeds the projected demand for parties to dispute, thus generating a solution with neutral emission of CO2. Pilot Stadium designed by Arup engineers served as proof of this innovative cooling concept during a visit to the country in the evaluation of the FIFA Committee for the qualification of nominations phase.

Globally, 1. 600 million people have no access to electricity. Essential for human development, energy is not used in the world in political, economic, social and environmental awareness. It is everybody’s problem, not only in the countries of the South, but also from the North. There is enough for everyone.
The problem of unequal enjoyment is not only technological or economic, but also political. It is believed that technology solves the problems of development, and entrusts this task without having earlier questioned what it means to develop and be developed. We must rethink the welfare of this consumer society, understand the welfare of society is not associated with the production and wasteful consumption of energy, but production and rational consumption, sufficient and equal for those who populate the Earth. Thus, we had to talk in terms of human development, understood as the expansion of capabilities so that people can decide on their future freely. This concept is closely linked to access to energy by the relationship between energy consumption and improvement of indicators of poverty, health, education, etc.
how to move forward in this direction? For the sake of sustainability, we must assume that access to energy and its consumption must be respectful with nature and the people who inhabit every environment. But it cannot be the market who dictate the rules of the energy game; These must be agreed with the communities living in the areas of supply and determined by the productive dialogue between the global and local wisdom. Secondly, we must take action. This methodology should be reflected not only in the speeches of development cooperation but in public policies of States, in order to regulate transnational corporations that exploit resources and financial institutions that guarantee economically scaling up processes. We recognize that, in response to the global situation, this will require an exercise of ingenuity by those who marked the international agendas.

The price of oil continues to rise, new collection of solar energy technologies are developing, and are becoming more attractive. One of the latest innovations, revealed recently by the Idaho National Laboratory, is an improved variety of collector solar, so effective, that can even work at night. The key to everything is in nanotechnology. With this new technology, millions of tiny metal hoops are moulded as microantennas, which can be placed on almost any material, including plastic sheets. These microantennas in the form of spiral are about 1 / 25 of the width of a human hair.
They are so small that they resonate in the interaction with the infrared rays of the Sun. This resonance can be translated into energy. During the day, the Earth absorbs a large amount of this infrared energy radiating at night, allowing these microantennas to collect solar energy even after the sunset. Conventional solar panel can convert around 20% of infrared rays into electricity. The research behind this new technology team, believes that it can achieve an efficiency of about 80%. In addition, conventional solar panels are expensive to produce, because they rely on Silicon of high degree, which is becoming increasingly expensive. These new solar collectors can be manufactured by much less, moreover, the research team is intended to create nanoantenas as cheap as possible in order to support security systems online, Panama energy of a computer consulting company and provide the necessary services in electricity for a home or business. But everything is not ready yet.
A major obstacle remains. Although these solar collectors are able to collect solar energy, they can not currently transmit this solar energy into usable electricity. The Sun’s infrared rays hitting the nanoantenas and generate a current which has a frequency ranging ten billion times per second, which is more bigger than a normal oscillation of existing appliances. However, the research team working on it. At this time, these antennas are good at capturing solar energy, but are not very good in your conversion, but there is a very promising ongoing exploratory research.

To date, relevant to the types of information technologies are developing an avalanche. Including specialists in this field in a state of continuous development of the qualification of knowledge to keep pace with the continuous updates and be informed of developments. But to the layman the rate of development of information industry and in fact very clever. And this at the moment, without doubt, leading the basis of information in the industry need to learn everything. In order to be able to understand the complex situations of information reality, you need timely assistance of experts. Well or walkthrough that was opportunity to suggest how to use specific features of software content. Especially taking into account that different programs occur daily, and with them must not only learn, but also normally interact. Find the resources where it would be possible to acquire data from very different areas of information of new products, starting from the dns setting and ending with step by step instructions associated with certain computer filling in our time is not able to present much difficulty.
However, the claim that many such sources, in fact impossible. Often these resources are either fully terminology assembly of articles that are able to understand only the experts, or overly simplistic and not always universal algorithms work. Yet the real find, including data that will not be available only to professionals, as well as ordinary users, and in this case is correct and detailed. For different users interact with databases and information or e-mail systems is a real pain. However, all about this that they have not received detailed explanations, which would be as soon as you can simply explains to the principles of a particular program. In this case, even for the masters especially the interaction with specific Web server or the individual terminals may not be particularly scrutinized. After all, including the activities of common wasps vindous able to open the other positions. No secret that the windows to create and Many other moments, such as organizing a remote access can, including the experts do not face such issues previously cause certain difficulties. Exceptionally literate detailed explanations allowed to find a dignified way out of difficult situations. In addition, the subject directories have a chance to pick and ready-made scripts and other materials that make it easier to work activities specialist.
When we are interested in having a website we must decide what type of site will meet the goals we achieve. If we only need to inform the visiting public of the products or services we offer sufficient choice to develop static web pages. If instead we want the visitor to interact with our website, then required to develop dynamic web pages. Logically a dynamic web page will take much longer to implement and therefore have a greater cost. A static website is one that is basically information, the visitor and webmaster can not interact with the page to alter its content. NOT use databases or programming is required.
To develop a static website is sufficient to use HTML. Below the structure could have a website that tries to present their products or services: 1. Main page with Flash header 2. Page “about us” 3. Shipping Policy page 4. Page FAQ 5.Contact page (address, telephone and electronic mail) 6. Payment page: Giro, courier service in July.

So far, neither of which is not known when and who invented the first samovar. Many believe the country is Russia samovar, but it is not. The first semblance of a samovar can be found in Ancient Rome and China. It was a large vessel, which had the chimney and ash, the principle of his actions was the same as a conventional samovar. Also, there is a perception that the first samovar yet invented Tula, who took with him to the Urals, Tula smith-industrialist Nikita Demidov in 1701.
Once on the uninhabited place, longing for the hot brought down, and they came up with a widget, which itself is all cooked, initiating the samovar production. In Russia, a samovar was already known from 30-40 years of the XVIII century. The first mention of a samovar and samovar production is mentioned in 1745, "the Register how many made and given to Mr. Gregory Akinfievich nobleman (Demidov) in different copper utensils title in 1745 and at what price the market is 'and' seizure of property Onega, second-class monastery ', which dates from 1746 and a year where, among other things mentioned, and' two samovar with green copper pipes. " But the available data do not show the what the shape and the device was samovar at the time. We only know that in these years, the samovar is used in the Urals, and later in Moscow, Tula, St. Petersburg, and in the XIX century samovar appeared in Vladimir, Yaroslavl, Vyatka province.
Would it surprise you to know that when the Gallup organization work investigated the factors the most common was "I know what is expected of me at work" topped the list? And companies that had the greatest number of this factor were more productive, helpful and creative. The ability to set clear expectations is an essential skill that every leader must master. And yet I'm sure not often think we communicate our expectations to others, especially those with whom we work. Why communicate our expectations is as important if everyone has job descriptions – certainly know what that is supposed to do at work Well it turns out that "knowledge is expected of us" is more than just the statement of responsibility standard work. You know how you fits and works with those around you and how expectations change when circumstances change. It is a larger picture of our work is what helps teams to achieve complex projects, adapt to changing situations and is the foundation for true teamwork. The best teams make sure to communicate to each other what they need as pieces of the project that are passed between team members – in explicit terms related to timing gear, quality and content. And when problems occur they will quite naturally try and focus on the process and not the person. The best teams strengths and learning styles of each person on the team that helps them to adapt when the inevitable challenges occur. Whether in good times and bad they know what they can expect from each individual's computer.
In some countries, well-meaning organizations are working without licenses and without coordination. It’s all more or less chaotic, he says. Not just raising money, but also better use of resources. In many cases, there is the will and the resources to treat diseases in the developing world, but basic infrastructures are lacking to those countries. Without roads, energy, clean water and basic health care services including professional nursing providers is simply impossible to carry medicines and treatments that may save lives up to the patients who need them, Nathanson notes. Definitely, Venezuela case that concerns us, must take seriously the problem of health, not only to provide security for its inhabitants, lead them to appropriate services, which ensure for the future a healthy generation, able to encourage that workforce that allows you to develop, consider also what manifests itself, that some countries are doing with the creation of community health networks formed by volunteers, most of whom are women. Many of these volunteers are wives of influential community leaders in the position of making health a priority issue. In India, nurses are being employed in rural areas to assist in the classification of populations and to identify patients who may need to navigate to get more advanced in the doctor’s Office or hospital treatments.
The current Venezuelan Government that identifies with the socialism of the 21st century, should give priority to health, know to invest foreign exchange generated by oil in pro to guarantee a service of health that favours its citizens, give way to a new culture of health, implemented all the apparatus involving the service, from hospitals, clinics technologymedical, nurses, medicines. * Source: Wharton.
