Concealed wiring they are laid under plaster, in closed channels of building structures, voids of large-panel ceilings, walls. It can be replaceable or non-replaceable. Replaceable hidden wiring provides for the replacement of damaged wires between pull boxes.

Wires of the APR, PV, PRV, APV, APRV, etc. brands are used for the installation of hidden electrical wiring in plastic, rubber-bitumen and semi-solid pipes.

Laying wires in the voids of walls and partitions completely eliminates punching and finishing work. The wires are pulled using a pre-stretched wire with a diameter of 1,0-1,5 mm. Wires of the APR, APRV, PRV, APV, PV, APPV, PPV, APPVS and PPVS brands are laid in the channels.

Replaceable concealed wiring is laid in steel pipes, which are laid in the channels and grooves of walls and ceilings, followed by sealing them with mortar. For this type of wiring, wires of the APRTO, APRV, PRV, APV and PV brands are used. As noted above, wires are pulled into pipes after welding is completed.

Non-removable hidden electrical wiring is laid under a layer or in a layer of plaster along the shortest path; in this case, wires of the APPV, PPV, APPVS, PPVS, APN and APV brands are used.

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. ... >>

The phases of the moon affect rainfall 08.02.2016

The phases of the moon affect the amount of precipitation - however, very little. This discovery was made by atmospheric scientists from the University of Washington (USA), led by doctoral student Tsubasa Kohyama and Professor John Wallace.

The phases of the Moon arise because it revolves around the Earth - with a period of 27,3 days - and is illuminated to varying degrees by the Sun at different points in its orbit. We are interested, however, not in illumination, but in the very fact that on different days a natural satellite of our planet is above different parts of its surface. The moon, with its attraction, slightly pulls the Earth's atmosphere in its direction, making the atmospheric column higher, as, accordingly, atmospheric pressure. Such a relationship between the phases of the moon and atmospheric pressure was first noticed back in 1847.

The increased pressure raises the temperature of the air. The warmer the air, the more moisture it can hold. As a result, there is less rainfall.

Kohiyama and Wallace and colleagues first tested these theoretical findings experimentally by analyzing data collected over 15 years (1998-2012) by the Tropical Rainfall Measurement Mission, a science satellite jointly launched by NASA and the Japan Aerospace Agency. It turned out that when the moon is at its zenith, the rain really becomes a little weaker - although only by 1%, which is not noticeable to the average person, but, nevertheless, is a statistically significant difference.

This discovery will help in testing climate models for their accuracy. If the climate model is accurate enough, it should take into account the weakening of rain in areas over which the Moon passes.

Scientists from the University of Washington intend to continue their research and find out, in particular, whether the phases of the moon have a stronger effect on heavy rains, up to an increase in their frequency.

Note that the Moon affects many processes occurring on Earth. Perhaps the most famous effect is the tides that occur when the Moon is at perihelion - i.e. when it is closest to the planet, because the moon's orbit has the shape of an ellipse. Last September, the full moon and perigee were separated by only one hour, so it was possible to see the surface of our planet's natural satellite as detailed as possible, with simple binoculars or even with the naked eye.
