IT system - a system in which the neutral of the power supply is isolated from earth or earthed through instruments or devices having a high resistance, and exposed conductive parts are earthed.

IT grounding system

1 - grounding resistance of the neutral of the power supply (if any); 2 - ground electrode; 3 - open conductive parts; 4 - grounding device; PE- - protective conductor (grounding conductor, zero protective conductor, protective conductor of the potential equalization system).

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Yeast medicines 21.02.2022

Scientists have edited the yeast genome to produce a key ingredient in drugs for age-related dementia and Parkinson's disease.

Researchers at Imperial College London and the National University of Singapore have been able to turn friendly mushrooms into biofactories to produce a chemical compound, an alkaloid used in drugs for dementia and Parkinson's disease.

Today, this alkaloid is obtained from extracts of ergot, a parasitic fungus that infects wheat and rye. From 10 to 15 tons of compound are produced annually. Growing ergot in such volumes for medical purposes harms the environment. Therefore, the researchers decided to try an alternative method using yeast.

The scientists isolated genes from ergot and inserted many variations of them into the genome of baker's yeast to produce a cell that could make a key drug ingredient.

"Yeast has been a key part of human civilization for thousands of years, helping us bake bread and brew beer. But our relationship with this familiar microbe is evolving. We've been able to use fungal cells to act as miniature factories for producing drug precursors," says Paul. Fremont, professor at Imperial College London and one of the leaders of the study.

Baker's yeast was also one of the first cellular organisms whose genome was studied in detail. This made them an ideal model for genetic engineering. Using the same fermentation process used to make beer and bread, the modified yeast consumed sugar and produced about 2 mg of the compound in a 1 liter reactor.
