SMS will save a stolen car

28.11.2000

One of the Austrian companies engaged in the production of anti-theft systems, presented at the fair "Security 2000", held in Essen (Germany), a new development.

This is a system that, in response to an SMS (short text message) sent from the owner's mobile phone, will be able to stop the stolen car by cutting off the supply of gasoline, as well as lock the doors, thus preventing the hijacker from getting out of the car before the arrival of the police, or draw the attention of other drivers on your car, blowing red smoke from the exhaust pipe.

Other topics of the Essen trade fair dedicated to security and protection technologies were identification devices for ATMs and personal computers, which use technologies for recognizing fingerprints, irises, voices, signatures, etc. - the so-called biometrics, as well as video monitoring systems.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

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. ... >>

Good cholesterol protects against sepsis 01.04.2022

"Good cholesterol" refers to high-density lipoproteins, or HDL - large molecular complexes of lipids and proteins. The more of them, the less "bad cholesterol" in the blood, that is, low and very low density lipoproteins. "Bad cholesterol" increases the likelihood of atherosclerosis, "good" - reduces, in fact, that's why they are called that.

Lipoproteins carry lipids from place to place, from tissue to tissue, and as such they influence various physiological processes - not only lipid metabolism, but also, for example, immunity. Researchers at the University of Kentucky and the University of Michigan noticed that patients with sepsis generally have lower "good cholesterol" levels than healthy people, and the lower the level, the worse the clinical prognosis.

Sepsis, or blood poisoning, is an inflammatory response to a bacterial infection. Inflammation can be so severe that it will disable some organs and lead to death. Experiments with mice confirmed that HDL levels are associated with septic inflammation: animals that were known to be low in them were more likely to get sepsis when bacterial infection. It is likely that HDL somehow helps control the inflammatory response so that it does not turn into damage.

By increasing the level of "good cholesterol", you can cope with sepsis that has already begun. High-density lipoproteins have synthetic analogues that act in the same way as real HDL; clinical studies show that such analogues are quite effective in preventing cardiovascular diseases.

One of these analogs was injected into mice with sepsis, after which the inflammation in them subsided, the internal organs (for example, the kidneys) began to work better, and in general the mice were more likely to survive. It is possible that analogues of "good cholesterol" can be used in humans.
