When lifting a load on the hook using a rope tied with a hook knot, the thickness of the rope should be taken into account. If the cable is thick enough in relation to the hook, it can be laid with a single hook knot and safely lift the load.

A thin cable laid with a singleknot, can slide off the back of the hook, and if it is thin in relation to the hook, it is laid hook knot with a hose. This greatly increases the reliability of lifting the load.

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 ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Axis Q3709-PVE panoramic network camera 30.04.2015

Axis Communications has introduced the first model in the new Axis Q37 camera series. Providing complete situational awareness in a wide surveillance area, the Axis Q3709-PVE triple 4K dome camera is suitable for video surveillance in city streets, as well as in logistics centers, airports and railway stations.

"Due to the one-piece design, one such camera monitors large areas and provides high detail of the required areas," explained Erik Frannlid, director of video product development at Axis Communications. , parking lots and for organizing security around the perimeter - that is, where you need to constantly monitor and study large areas in detail, ensuring that operators are fully aware of the current situation.

According to Axis, the camera is easy and cost-effective to install. The factory focusing of the lenses eliminates the need to adjust the focus manually. The device comes in a stylish, discreet vandal-resistant housing that is easily repainted to your desired color, and is equipped with a removable casing that not only protects against weather conditions, but also allows you to blend the camera well into your surroundings.

Axis Q3709-PVE provides a 180° panoramic view with up to 33 megapixels. The camera is capable of transmitting a video stream with a resolution of 3x4K at 30 frames per second or 3x11 megapixels at 20 frames per second.

The unit is outdoor ready and certified to IP66 and NEMA 4X ratings, as well as IK10 rating. The Axis Q3709-PVE operates over a wide temperature range with standard Power over Ethernet (PoE+) power. In addition, the model is equipped with a video motion detector and a warning system about attempts to disable.

The camera is compatible with a wide range of video management software developed through the Axis Software Development Partner Program and Axis Camera Station software. In addition, support for local video storage, the Axis Camera Application third-party installation platform, Axis video hosting system, and the ONVIF specification makes it easy to system-integrate the camera and extend its functionality with intelligent video technologies and third-party software applications.

The Axis Q3709-PVE is scheduled to be available through Axis' distribution network in the second quarter of 2015. The camera's suggested retail price is $2399.
