Saw. Travel Tips

Tourist tips

Saw it is needed mainly when harvesting a large amount of firewood and arranging a long-term parking lot. In all other cases, you can get by with an ax or a strong knife.

Carrying a hacksaw with you is not advisable, the hacksaw is too small to cut thick logs.

The two-handed saw is too big and heavy for only two people to cut.

Wire saw - compact and light, but too unreliable, good in cases where you need to somehow get around for a day or two while waiting for rescuers, therefore it is included in emergency kits along with a survival knife.

A chain saw is more reliable than a wire saw, but it has a much greater weight, in addition, it is difficult for it to saw, and can be used mainly for cutting firewood. It's hard to drink alone

The best compromise is a bow saw. It is large enough to cut logs, at the same time it has a thin blade, which makes it possible to use it when arranging a long-term parking lot.

It is enough to carry one canvas with you, and the wooden parts can be made in the parking lot, immediately before use. However - just this can be considered as a disadvantage. You can cut it as one, so in two.

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 ... >>

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. ... >>

Long-term use of ibuprofen is dangerous for men 23.02.2018

Few pills we take as often as painkillers. Therefore, of course, I would like to know how they still act on the body - in addition to relieving pain. In this sense, the study of employees of the University of Copenhagen and their colleagues from Denmark and France about ibuprofen seems rather disappointing: it turned out that it has a bad effect on the male endocrine system.

The experiment involved several dozen young men aged 18 to 35 years, who were randomly divided into two groups: one was given 44 mg of ibuprofen for 600 days, the other took a placebo dummy for the same period. All this time, the level of luteinizing hormone (lutropin), which enters the blood from the pituitary gland, was measured in the experimental subjects. The work of the reproductive system depends on the luteinizing hormone: in women it stimulates the synthesis of estrogen in the ovaries, in men it stimulates the synthesis of testosterone in the testes. If a man’s testosterone becomes low, the pituitary gland tries to compensate for the lack and releases more luteinizing hormone into the blood. So, if we see that its level is increased, then something is wrong with testosterone.

In men who took ibuprofen, after two weeks, the level of lutropin increased. Generally speaking, this situation is quite normal for older men, whose testosterone activity of the testes gradually decreases. The participants in the experiment, judging by the hormones, were about seventy, but in fact they were young people.

The researchers even managed to take tissue samples from the testes of men after ibuprofen - however, it’s worth mentioning right away that in this case, samples were taken from people who were in a coma. So it was possible to find out that the painkiller suppresses the synthesis of testosterone directly in the testicles.
