Comments on the article

The degree of air pollution by the main pollutants is directly dependent on the industrial development of the city. The maximum concentrations are typical for cities with a population of more than 500 thousand inhabitants. Air pollution with specific substances depends on the type of industry developed in the city. If enterprises of several industries are located in a large city, then a very high level of air pollution is created.

In order to determine air quality based on the results of observations, the measured values of concentrations are compared with the maximum one-time maximum allowable concentration and the number of cases when MPCs were exceeded is determined.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Seed Bank in the Arctic 04.09.2007

An international seed bank for agricultural crops is being created in Svalbard, with a capacity of three million seed samples.

The diversity of crop varieties is declining all the time. For example, in the United States in 1903, more than 8000 varieties and varieties of cultivated plants were grown, and in 1983 - only 600. Such a reduction in the range means that the unexpected appearance of a pathogen or pest that has adapted to the most common varieties can completely deprive humanity of one or more a different culture.

There are currently about 1400 seed vaults in the world, but many of them are unreliable - under the threat of natural disasters, domestic riots, wars or mismanagement. Despite global warming, the authors of the project expect that in the Arctic cold (the temperature in the storage chambers will be maintained at -18 degrees Celsius), the seeds will not lose their germination capacity for at least two centuries.

The Svalbard collection will become an inviolable reserve of mankind. All cultivated plants of the planet together with their wild relatives will be stored here. Seeds from storage will be released for sowing and propagation only as a last resort, when all other sources of such seeds are exhausted or destroyed.

Construction should be completed before the end of 2007, it will cost $75 million; funds provided by the government of Norway. In a mountain at an altitude of 130 meters above sea level (this mountain will not be flooded, even if all the ice of Antarctica and Greenland melts), two chambers are created, connected by a tunnel.
