Take a photo before the explosion

18.10.2004

To neutralize bombs planted by terrorists, suspicious mail, or packages forgotten in a public place, which may also contain a bomb, sapper robots are often used.

The robot shoots a suspicious object with a powerful jet of water or even blows it up. In any case, the police can only hope that they will be able to pick up fragments of an explosive device on which there will be fingerprints, which would greatly facilitate the investigation.

Engineers from the University of Calgary (Canada) proposed to add a device for developing fingerprints to a demining robot. The prints are made up of traces of fat and amino acids secreted by the skin. Cyanoacrylate reacts with these compounds - the very substance that instant glue consists of, and the prints become visible.

The robot is equipped with a vessel with liquid cyanoacrylate. The vessel is heated by an electric spiral to 65 degrees Celsius, and the cyanoacrylate evaporates and its vapors are directed by a fan from a nozzle mounted on the robot's arm to the object under study. After a few minutes of fumigation, white fingerprints appear.

The operator, controlling the robot from a safe distance via cable or radio, points a high-definition digital camera at them and receives an image of the prints, after which the bomb can be destroyed on the spot or carefully removed for detonation.

The prototype device proved its effectiveness. The FBI and other intelligence agencies became interested in the invention.

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 ... >>

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 ... >>

SONY Unveils DVD Burner with Internet Access 23.04.2003

Sony has introduced a new digital recorder equipped with a DVD drive and 80 GB hard drive called the NDR-XR1.

This device differs from its counterparts in that it can connect to the Internet via a broadband channel. In addition, the NDR-XR1 is equipped with a built-in browser that allows the user to browse the web using a TV connected to this unit.

It's not so easy to find a suitable name for the NDR-XR1, the set of functions that this device has is extremely large. It allows you to record TV programs on the built-in hard drive, a signal from a camcorder via the DV input, as well as images from Memory Stick media. Of course, all this can then be rewritten to DVD discs. In addition to being able to read DVD-R/RW, DVD Video and many CD formats, the NDR-XR1 can burn DVD-R/RW discs. Through the Internet, the NDR-XR1 can connect to special servers containing TV programs, making it easy to automatically program it to record specific TV broadcasts.

In addition, the user will be able to control the NDR-XR1 via the Internet using his mobile phone, which must also have access to the Network. In general, this device can do almost everything related to playing and recording video and TV programs.

Perhaps its only drawback is its high price, which is about $1200.
