Task external lightning protection system - a fraction of a second before direct contact to catch the lightning discharge and send it to the down conductors to the ground.

The external lightning protection system, organized according to the principle of a lightning protection mesh, is designed individually for each specific house. The material of the roofing, the angle of the roof, the dimensions of the dormer windows, the dimensions of the roof windows, the presence of antennas, the material of the drainage systems, the method of their installation, the number of pipes and their dimensions - all this and much more is important when designing such a system (Fig. 14.9).

Depending on the material of the roof and the wishes of the customer, the lightning protection part can be made of the following materials:

galvanized steel;
aluminum;
copper;
stainless steel.

On the roof, everything is fixed with the help of special fasteners, different for each type of roofing, both in terms of the material of manufacture and the method of its installation.

This allows you to create a modern integrated system that meets the most stringent requirements for safety and aesthetic appearance, taking into account all the features of your home.

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 ... >>

Single EU Cell Phone Charger 20.03.2014

All cell phones sold within the European Union will be required to use a single standard charger. 550 out of 570 members of the European Parliament voted for such a requirement. In the next two years, this rule should be introduced into the legislation of all EU countries, and manufacturers will have another year to bring their products into line with the law.

According to parliamentarians, the transition to a common standard will help reduce "electronic waste", costs and inconvenience to consumers.

Note that in fact we are talking about the transition to the micro-USB connector, which is already used by most manufacturers, so the de facto requirement for standard charging was fulfilled at the stage when it was advisory in nature. Manufacturers who are out of step so far will have to take action if they want their products to remain on the European market beyond 2017.

The directive also streamlines the placing on the market of radio equipment, including cellular phones and modems. The need for this is due to the explosive growth in the number of products that can potentially affect the health of consumers and the work of each other.

Using information provided by EU members, the European Commission will determine the categories of equipment that will require mandatory registration in order to enter the market. A similar mechanism is already in operation in the US.
