Tattoos make you sweat

07.10.2020

Tattoo machines pierce the skin at a speed of 80-150 times per second, using special needles to inject pigment into the dermis of the skin. It would be strange if the sweat glands that sit in the dermis did not feel this.

Sweat has previously been shown to contain more sodium after tattoos. That is, the work of the sweat glands after a tattoo is different from the work of the sweat glands in normal skin. Another feature of "clogged" skin was revealed by employees of the Southern Methodist University and other scientific centers. They set up an experiment with several volunteers who had tattoos on their forearms or shoulders. The person put on a special suit that maintained the temperature at 48 ° C, and remained in such a suit for half an hour or a little more. The researchers measured the general body temperature and skin temperature of the tattooed and non-tattooed areas, as well as the amount of sweat that was released on them.

It turned out that tattooed and non-tattooed skin starts to sweat at the same temperature. This means that the nerve signals that control sweat glands work quite normally after a tattoo. But the amount of sweat from the tattooed skin was less - apparently because the sweat glands were damaged.

We sweat for a reason, but to cool down - overheating is dangerous for a variety of biochemical and physiological processes. If the tattoo is small, then most likely there will be no big trouble. But if the tattoo covers a large area of the skin, then the question arises, does thermoregulation suffer from an extensive tattoo? Maybe fans of large tattoos should somehow take care of themselves more carefully on very hot days, or something like that? Although specific clinical recommendations can be made here after the researchers experimentally study the physiology of lovers of "sleeves" and other large-sized tattoos.

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. ... >>

Electric car Hyundai IONIQ 6 18.07.2022

The Korean automaker Hyundai Motor Company has officially announced the serial version of the Hyundai IONIQ 6 electric car. The model is a sedan with the most aerodynamic "sloping" silhouette, its overall dimensions are 4855 x 1880 x 1495 mm (wheelbase - 2950 mm).

Just like other brothers in the IONIQ line, the novelty is based on the proprietary Electric-Global Modular Platform (E-GMP) with support for 400/800V charging architecture. Buyers will be offered a single-engine rear-wheel drive RWD version or a twin-engine all-wheel drive AWD version. In the latter case, the Hyundai IONIQ 6 electric car will receive a power of 239 kW and a torque of 605 Nm, which allows it to accelerate to 100 km/h in just 5,1 seconds.

It will also be possible to choose two battery options - 53 kWh or 77,4 kWh, a more capacious option will provide a range of 610 km on the WLTP measuring cycle. From a powerful 350 kW high-speed charge, it takes only 10 minutes to charge from 80 to 18% of the battery capacity. It also supports V2L (vehicle-to-load) technology, which turns an electric car into a mobile power generator.

The driver gets at his disposal two 12-inch screens with basic digital data and additional / entertainment information, respectively. Apple CarPlay and Android Auto systems are supported, as well as dual-channel Bluetooth connection with smartphones, for example, you can use one for calls and the other for streaming music at the same time.

The car is equipped with a digital assistant system - the driver receives a whole complex under the general name Hyundai SmartSense (Advanced Driver Assistance Systems).
