Comments on the article

It is recommended to make information signs for designating security zones of power lines from sheet metal or plastic material with a thickness of at least 1 mm and a size of 280x210 mm.

The information sign contains the words "Protection zone of the cable. Do not dig without a representative" (for a cable line), "Protection zone of a power transmission line" (for an overhead line), the distances from the place where the sign was installed to the boundaries of the security zone, arrows in the direction of the boundaries of the security zone , telephone number (s) of the organization that owns the line and a border 21 mm wide.

The background of the information sign is white, the border and symbols are black.

On reinforced concrete supports of overhead lines (VL), information signs can be applied directly to the concrete surface. In this case, it is allowed to use the surface of concrete as a background, and the size of the sign can be increased up to 290x300 mm.

Information signs are installed in a plane perpendicular to the axis of the power line (at the angles of rotation - along the bisector of the angle between the axes of the line sections).

For overhead lines, their installation is carried out on racks of supports at a height of 2,5-3,0 m, and for underground cable lines - on separate racks at a height of 0,6-1,0 m.

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. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

US Army polyethylene helmet 20.06.2018

The US Army is developing a new helmet for soldiers. It will be light, but that is why it is made not of Kevlar, but of polyethylene.

The new Second Generation Advanced Combat Helmet will be lighter than ever, while protecting the wearer from head injuries.

According to the developers, the helmet will be 24% lighter than all previous helmets for soldiers and will stop 9 mm caliber bullets, shrapnel and elements of improvised explosive devices. The helmet is being developed by the Natick Research and Engineering Center.

The weight of the new ACH II helmet will be only 1,4 kg. How are these savings achieved? Army engineers changed the material from Kevlar to plastic. Yes, on plastic, or as it's officially called "ultra-high molecular weight polyethylene". It is a semi-crystalline polymer that is used in everything from fishing lines to hip prostheses. It is durable, non-corrosive and lightweight.

The color of the helmet will be brownish-yellow, and it will be possible to change it to different camouflage patterns using fabric covers.
