Recorder XORO HSD-R545 - heavy artillery DVD

29.11.2004

Recently, DVD recorders have begun to attract the attention of amateurs.

The relatively low cost of these devices, the relative cheapness of recordable and rewritable discs, coupled with their high capacity, the emerging trend towards multiformat among the main manufacturers gives such recorders real chances to fill the vacancy that appears in connection with the abandonment of VHS video recorders.

The Xoro HSD R545 recorder, introduced by the company in the summer of 2004, is equipped with a built-in TV tuner and allows you to record video from various sources to DVD+R/RW discs at home.

The Xoro trademark belongs to MAS Elektronik AG (Germany).

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. ... >>

Methyl found in space 07.07.2023

Although the existence of active methyl cations in protoplanetary disks was suggested 40 years ago, it is only now that this important compound has been discovered and confirmed.

In 1977, a hypothesis was formulated that the monovalent methane radical, namely the methyl cation (CH3+), plays a decisive role in initiating chemical processes in the interstellar medium. However, detecting this molecular formation outside our solar system has proved extremely difficult.

Perhaps this is due to the high activity of methyl: its average lifetime in the free form is usually less than a thousandth of a second. As a result, it is unlikely to find a large number of such cations in one place and at one time, so that they can be detected using terrestrial telescopes.

However, thanks to an international team of astronomers, traces of methyl have been found in the protoplanetary disk d203-506, located in the Orion Nebula, using data from the James Webb Space Telescope and spectroscopic analysis. Star formation processes are actively taking place in this region, and d203-506 is the embryo of a relatively small star system: the mass of its star is approximately five times less than the mass of the Sun, and the mass of the protoplanetary disk is ten times the mass of Jupiter.

Where does this active cation come from in the protoplanetary disk? The researchers suggested that the reason lies in the strong ultraviolet radiation of Orion's Trapezoid, a compact cluster of stars located nearby. Under the influence of such radiation, hydrogen molecules (also found in the d203-506 composition) go into excited vibrational states, which makes them very active and facilitates their interaction with carbon, resulting in the formation of free methyl.

However, as the scientists note in an article published in the journal Nature, there are still several questions related to the excitation, chemical properties and spectroscopy of this molecule. Additional research is needed to definitively understand the role of CH3+ in the organic chemistry of the cosmos. This is important for elucidating the mechanisms of formation of more complex compounds in young stellar systems.
