Boat knot. Travel Tips

Tourist tips

Boat knot It is used when towing boats and during their parking under fire at the side of the ship only in those cases when there are people in them.

First, the running end of the painter is passed into the bow boat eye, with a lot - under the first can, then it is carried from above around the second can, the end is brought out above the cable and again led under the can, then the end of the painter is folded in the form of a loop and led under the hose made on top of the can.

Rice. 99. Boat knot

The boat knot is easily untied by pulling the running end of the painter lying on the can.

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 ... >>

Flight boots 21.04.2001

Moving around the space station in zero gravity, it would seem, is easy: you have to grab onto the walls and push off objects. But, having pushed off, it is no longer possible to slow down or change the direction of the flight, and at speeds developed in zero gravity, this can be dangerous.

American engineer Philip Watts and physiologist David Carrier propose to give astronauts the means for controlled zero-gravity navigation. If you stand on the scales, raise an umbrella above your head and start clapping it, opening and closing. At the moment the umbrella is closed, the scale will show a noticeable decrease in weight. This force of repulsion from the air in zero gravity will be enough for movement. But the umbrella is too bulky, and the suit with wings like a bat proved to be ineffective.

Since human legs are stronger than arms, the researchers suggest using mainly legs to fly around the station. A simple option is boots with elastic opening bells, which you can sort of run through the air, starting from it. For large and spacious space stations, a kind of bicycle with propellers rotated by pedals will be convenient. Both options are also good because they give the body a load, which is so necessary in conditions of weightlessness.

It is difficult to say whether the Americans know that Tsiolkovsky, almost a hundred years ago, proposed wings-fins powered by leg muscles for flights inside the space station.
