Match lift. Tips for the home master

Builder, home master

Matches... How many times do we use them in a day! To do this, you constantly have to open and close the drawer of the table or get them from the shelf - otherwise it’s impossible: he threw it on the table - the baby is right there.

I offer a match "elevator", which can be made from plexiglass, plywood, or even just from thick cardboard. I took the boxes - the elevator worked, the stack fell. Using matches, put them on top of the "high-rise building".

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

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 Secret of the Chameleon Language 29.04.2016

29.04.2016
Scientists led by professor of mathematical biology from the University of Oxford Derek Moulton (Derek Moulton) built a model of the chameleon language. The model allows us to understand how the reptile manages to unwind its tongue so quickly, grab the insect and swallow it.

It took more than 20 equations to calculate the movement. "When you look at these equations, they may seem complicated, but in essence this is Newton's second law, which all children learn in school. In mathematical terms, we used the theory of non-linear elasticity to calculate the energy in various layers of language, and how potential energy is converted into kinetic energy,” explains Derek Moulton.

It is known that the tongue of a chameleon is able to stretch to a length twice the length of its body, and unraveling occurs telescopically and very quickly. Recent studies have shown that if language were a car, it would be capable of accelerating from 0 to 100 km/h in one hundredth of a second. The secret is largely in the presence of special elastic tissues inside the tongue. In the core of the tongue there is a bone, and around it there are 10-15 layers of very thin muscle tissue. The model of British mathematicians was able to show how all these layers work.

Scientists believe that the study will be useful in bionics - the science of "copying" technologies from nature.
