Global shortage of materials an increasingly pressing issue

Modern society relies entirely on affordable raw materials. They are used for the manufacture of high-tech materials for various uses such as transportation, electronics, power, medical care and construction. However, a combination of reduced supply, global population growth, and sudden consumption increase in developing countries has put a great deal of pressure on material supply. In theory, the Earth's crust contains enough atoms to satisfy the world's demand over a long period of time, but in fact it is an economic, geopolitical, social, technical, environmental There are serious limitations due to factors.

This is a problem dealt with at the COST resource constraint world material conference. Dr. Erik Offerman, researcher at TU Delft, coordinates this event: 'To analyze the serious shortage problems around the world and explore solutions, policy makers and scientists from all sectors I will tie it. In addition to universities and research institutes, there are speakers from the industry (including Siemens, Tata Steel, Rolls Royce, Deutsche Telekom), Clingendael and Hague Strategic Research Center. (HCSS) ".

Together these lecturers provided a global geopolitical view of important issues. In addition to the technical aspect, this is very important. For example, Offerman points out the availability of important metals. Cobalt, indium and strontium are essential to our society. high Used for high strength "working horse" steel. Indium forms part of indium tin oxide species for modern touch screen. Key metals will also play an important role in the future of sustainable power supply. wind is an important element of the most powerful permanent magnets used in wind turbines. By using so-called nickel-base superalloys for power plant parts, we can increase their efficiency by 5%. Only this gain will be much greater than the current wind and solar energy gains. However, these superalloys contain important metal cobalt from Congo.

The supply of rare earth metals such as ruthenium is mainly from China, and platinum group metals are mainly mined in Russia.铌 Mine is mainly done in Brazil. "For environmental reasons, China officially limits the export of rare metals, but for geopolitical reasons there may also be reasons for geopolitical meaning that its supply can not be guaranteed and the price fluctuates sharply "Said Offerman. Therefore, finding new materials that are not so dependent on these important raw materials, recycling possibilities, sustainable mining and recycling economic design is an immediate problem for the Western countries, It is also very important. It is a good opportunity. environment

Finally, one of the most imminent problems in the world economy today (still under discussion) is the lack of global security assets. Savings want to keep some of their savings safe - supply of these assets is not sufficient (and more and more are currently owned by central banks). This reduces the pressure on real interest rates, raises financial stability problems, burdens the monetary policy, and may slow the growth of the global economy.

The increase in care shortage is a global problem. The rapid increase in mobility and immigration rates by health care system experts has led to the shortage of the country and hospitals. This shortage is thought to be critical as it affects the health of patients and the quality of medical treatment provided. In order to achieve health care outcomes, health care systems must overcome the lack of qualified medical staff. It is very necessary to hire graduate nurses and hire nurses. The purpose of this article is to discuss the global lack of care, especially in the United Arab Emirates.

Lack of care is considered a major obstacle to the physical and mental activities of nurses. This is a global crisis that caused the global health care industry. Care shortage is a problem from long ago, but it has increased rapidly over the years. Care deficiency is not only an organizational task but also an object of economic analysis; it has a major nurse who forms the backbone of health and wellness, where vacuum and deficiency are the result of the collapse of the public health sector It leads to. "The shortage of nurses refers to the situation where the demand of nurses exceeds supply" (lack of care, 2010). Since care by experts in Florence Nightingale in the 19th century,
