TN system - a system in which the neutral of the power source is solidly grounded, and the open conductive parts of the electrical installation are connected to the solidly grounded neutral of the source by means of zero protective conductors.

TN-S system - TN system, in which the zero protective and zero working conductors are separated along its entire length.

TN-S earthing system

1 - grounding conductor of the neutral (middle point) of the power supply; 2 - open conductive parts; N- - zero working (neutral) conductor; PE- - protective conductor (grounding conductor, zero protective conductor, protective conductor of the potential equalization system); PEN- - combined zero protective and zero working conductors.

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. ... >>

Smell dementia 28.12.2016

While there are several medications available to slow the progression of Alzheimer's, they are best taken in the earliest stages of dementia. The question is how to determine the onset of the disease. Existing methods include identifying risk factors such as the APOE-e4 gene through blood testing, neurological examination, neuroimaging, and the like. A new diagnostic method was proposed by researchers from the University of Pennsylvania (USA).

They took as a basis studies that showed that a decrease in the sensitivity of smell may be associated with Alzheimer's disease. After that, the scientists examined a total of 728 older people using the standard Montreal Cognitive Assessment Scale, as well as an olfactory test in which the subject identifies various smells with their eyes closed. Each of the patients underwent a preliminary examination using various neurological methods, after which the patients were divided into three groups: healthy elderly people, people with mild cognitive impairment and patients with Alzheimer's disease.

Using a cognitive test, scientists were able to correctly identify 75% of patients in the mild cognitive impairment group. With the addition of the results of the olfactory test, the result rose to 87%, which is quite important, since mild cognitive impairment usually occurs several years before the onset of Alzheimer's disease. The combination of cognitive and olfactory tests improved the accuracy of identifying patients included in other groups.

The researchers are now working to reduce the time spent on the olfactory test from 5-8 minutes to three and confirm that the shorter time does not affect the result. In addition, scientists are going to find out if protein markers of Alzheimer's disease, which are present in the olfactory region of the brain before the onset of dementia, can be detected in the nasal fluid in order to develop another diagnostic tool.
