Comments on the article

Subjects polishing iron products are immersed for some time in a mixture consisting of 1 part sulfuric acid to 20 parts by volume of water, then the object is removed, rinsed thoroughly with water and dried in sawdust.

After drying, it is immediately immersed for one or two seconds in nitric acid, after which it is rinsed again with water, dried again in sawdust and then carefully wiped. In this case, the surface of the object becomes shiny, like glass.

Only in the above way can such perfect polishing be achieved.

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

The science of petting a cat 05.04.2023

Scientists have figured out how to properly stroke cats so that they like it.

According to Dr Lauren Fink, an expert at Nottingham Trent University, there is a right way and a wrong way to pet a cat, and if you do it wrong it can be dangerous.

While most people think that cats love to be stroked, it really depends on each individual animal. Experts advise starting by stroking the cat's head and neck, and then moving on to the chest and back.

It is also important to monitor the reaction of the cat - if she starts wagging her tail, then this means that she does not want to be stroked and she needs to be left alone.

Experts also warn of the dangers of stroking a cat's belly, as it can lead to a seizure. Instead, they advise petting cats only on the back.

Experts also note that improper petting of a cat can lead to injury to the animal. For example, if you stroke a cat against the coat, it can be painful for her. Therefore, you should stroke the cat in the direction of hair growth.

It is also important not to press too hard on the cat's body while petting, as this can cause pain and discomfort.

Thus petting a cat is an important part of interacting with an animal, but you need to know the right way to do it in order to avoid injury and discomfort for the cat. Therefore, if you decide to stroke your cat, do not forget about the recommendations mentioned above, observe the reaction of the animal and, most importantly, let him determine when he wants to stop ironing.
