Comments on the article
Metal detector is an electronic induction device that allows you to detect metal objects in a neutral or weakly conductive environment (in soil, water, walls, wood, under clothing and in the trunk, food, in the human and animal body, etc.), without contacting them, informing about this fact of the operator (beep, arrow deflection, etc.).
That is, the concept of "metal detector" contains only the definition of the presence of an object made of metal.
Metal detector - this is a device for determining not only the presence of metal objects, but also capable of classifying what material this object is made of: ferromagnetic or non-magnetic, i.e. with the possibility of discrimination.
The separation of metals according to their qualities is the basis of discrimination, i.e., the definition of "non-ferrous" or "ferrous" metal, respectively.

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

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. ... >>
| Random news from the Archive First successful robotic liver transplant
19.07.2023
Transplant surgeon Dr. Adil Khan and his team performed the first robotic liver transplant in the US at Barnes-Jewish Hospital. Now this innovative procedure is planned to be introduced in other clinics.
A 60-year-old patient suffering from liver cancer and cirrhosis caused by hepatitis C underwent a successful operation using advanced robotic equipment, while the chief surgeon controlled the operation from a nearby console.
"The transplant was a success: the new liver began to function immediately and the patient made a full recovery without complications," said Dr. Adil Khan, who led the surgical team from the University of Washington School of Medicine at Barnes-Jewish Hospital.
The recipient felt comfortable and regained mobility within a month after the operation, expressing a desire to return to golf and swimming. It usually takes about six weeks to recover from such an operation.
The hospital has focused on developing cutting-edge technology to minimize the invasiveness of operations and speed up patient recovery. Surgeons have already successfully completed more than 30 kidney transplants and other bile duct, pancreas and stomach related procedures using the robotic system. However, this operation was the first robotic liver transplant in the United States.
Liver transplantation is one of the most complex abdominal surgeries. Usually, the surgeon needs two incisions - 10 and 40 cm. However, in this case, the surgeons managed to get by with only 1,5 and 15 cm incisions.
The duration of the operation was a little over eight hours, but surgeons believe that the time of the operation will decrease as the procedure becomes more widespread and improved.
