Comments on the article

An ordinary household socket does not have contact markings and the connection (phasing) of the phase and neutral conductors to it is carried out as necessary, at the discretion of the electrician.

For myself, I adopted the rule that the phase conductor after connecting and installing the outlet should be on the right side when you look at it, respectively, the neutral conductor on the left side.

- such a sign or letters PE usually mark the contact of the grounding (protective) conductor

Installation, connection, phasing of a household outlet

Phasing of a household single-phase electrical outlet with and without grounding.

The installation height of sockets is not regulated in any way, except for two cases of installation, in children's institutions, the height from the floor should be 180 cm, and the distance from pipelines, bathtubs, sinks, etc., should be at least 50 cm.

In other rooms, in my experience I use the following dimensions of the installation:

height from the floor of living rooms and office premises, 30 cm;
height from the floor of bathrooms and kitchens, 110 cm;
the distance from the corners of the premises to the outlet, I accept 50 cm;
distance from the corners of the door frame to the socket, from 15 to 25 cm.

The recommended cross-section of connected wires is 2,5 square millimeters.

A circuit breaker for protecting socket groups, it is better to apply for a current of not more than 16 amperes.

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. ... >>

New system for nanotheranostics 12.07.2019

Scientists from the Federal Polytechnic School of Lausanne (EPFL) and the University of Geneva (Switzerland) have developed a new nanotheranostic system that uses "harmonic nanoparticles" - a family of metal oxide nanocrystals with unique optical properties: they respond to excitation not only from ultraviolet, but also from infrared light which is much safer for the patient.

Theranostics is a developing field of medicine, the name of which contains the words "therapy" and "diagnosis". The idea of theranostics is to create drugs and treatments that are simultaneously used for early diagnosis of the disease, and for treatment, and for monitoring the patient's response. This saves time and money, and may bypass some of the unwanted biological effects that can occur when these strategies are used alone.

Today, nanoparticles are increasingly used in theranostics, which combine diagnostic molecules and drugs into a single agent. The nanoparticles act as carriers for a molecular "cargo" such as a drug or a radioisotope for cancer patients undergoing radiation therapy. This "transport" is directed to specific biological pathways in the patient's body and can avoid damage to healthy tissue.

Once in the target tissue, the nanoparticles either help make diagnostic images or deliver their payload (or both). Specialists control them with the help of light. It is an advanced "nanotheranostics" technology that has become a mainstream of research. Although it has numerous limitations, there are disadvantages that must be overcome.

A new system developed by the Gerber group avoids these problems by using bismuth-ferrite "harmonic nanoparticles" based on silicon oxide, which carry light-sensitive molecular weights. These systems can be easily activated with near infrared light (790 nanometers) and imaged at longer wavelength for drug discovery and isolation processes. Both of these features make the system safe for patients.

Once the light is triggered, the nanoparticles release their cargo - in this case, L-tryptophan, which the researchers used as a model. The scientists monitored and quantified the release of the "cargo" using liquid chromatography and mass spectrometry.
