Comments on the article

7.2.58. Grounding and protective measures for the safety of electrical installations should be carried out in accordance with the requirements of Ch. 1.7, 7.1 and additional requirements given in this section.

7.2.59. The movable metal structures of the stage (stage, arena) intended for the installation of lighting and power electrical receivers (soffit trusses, portal scenes, etc.) must be connected to protective grounding using a separate flexible copper wire or cable core, which should not simultaneously serve operating conductors.

The connection of the rotating part of the stage and the equipment placed on it is allowed to be carried out through a ring contact with double current collection.

7.2.60. Metal cases and structures of cinema technology devices, as well as distribution systems and networks of electro-acoustics, television, communications and signaling must be connected to protective ground.

Electrical and sound-reproducing film-technological installations, as well as communication and television equipment that require a reduced noise level, should, as a rule, be connected to an independent grounding device, the grounding conductors of which should be located at a distance of at least 20 m from other grounding conductors, and the grounding conductors should be insulated from conductors of protective grounding of electrical installations.

The resistance of an independent grounding device must comply with the requirements of the equipment manufacturer or departmental standards, but should not exceed 4 ohms.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

ZOTAC ZBOX Magnus ERX480 VR nettop 31.10.2016

ZOTAC introduced the ZBOX Magnus ERX480 small form factor computer, designed for gamers.

The developer calls the novelty the world's first mini-PC with an AMD Radeon graphics accelerator suitable for virtual reality (VR) helmets. The nettop uses a discrete graphics card AMD Radeon RX480 (Polaris architecture), endowed with 4 GB of GDDR5 memory with a 256-bit bus.

The "heart" of the mini-computer is the Intel Core i5-6400T processor of the Skylake generation. This 14nm chip has four processing cores with a nominal clock speed of 2,2GHz (dynamically boosted to 2,8GHz). Up to 32 GB of DDR4-1866/2133 RAM is allowed.

Nettop can be equipped with one 2,5-inch drive, as well as an M.2 solid-state module. There is an SD / SDHC / SDXC card reader, Wi-Fi 802.11ac / b / g / n and Bluetooth 4.2 wireless adapters, a dual-port Gigabit Ethernet network controller.

ZBOX Magnus ERX480 can output 4K image at 60Hz refresh rate. To connect displays, there are two HDMI 2.0 connectors and two DisplayPort 1.3 interfaces. There are USB 3.1 Type-C, USB 3.1 Type-A, USB 3.0 (x2) and USB 2.0 (x2) ports. New dimensions: 210 x 203 x 62,2 mm.
