Hidden carnation. Tips for the home master

Builder, home master

It happens that the head of a nail or the head of a screw connecting two wooden parts needs to be hidden, disguised.

Here is one way. Peel off a thin layer with a chisel - literally wood shavings (but not completely) in the place where you need to drive a nail, and drive it in. Then drip glue and glue the shavings in place. The head of the nail will disappear without a trace.

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 ... >>

Holographic display for mobile devices 26.04.2015

Scientists from the Swinburne University of Technology in Melbourne, with the support of scientific foundations from Australia and China, have developed a technology that allows displaying holograms on the screen of a mobile device. To see such images, additional devices such as stereo glasses are not required.

The technology is based on the holographic method developed by the Hungarian physicist Dennis Gabor, who received the Nobel Prize in 1971 for his invention. The method consists in recording and displaying not only the amplitude of light waves reflected from objects (as in photography), but also the phases of these waves using a laser.

To reproduce this method in a mobile display, the researchers proposed using a promising material in the semiconductor industry called graphene. As scientists have found, this material is able to refract the light passing through it at various angles and recreate the recorded three-dimensional image with a viewing angle of up to 52 degrees.

"If you can refract light, you can create a lot of optical effects," said Ming Gu, director of the Center for Photonics Research at Swinburne University of Technology. smartphones and tablets with a wide viewing angle.

The new technology, according to the researchers, could also find applications in the military industry, medical diagnostics, distance education and the entertainment industry.

The creation of holographic images that do not require special devices for their viewing is being done by many researchers around the world. So, in the summer of 2014, a system for displaying images hanging in the air, like holograms in Star Wars, was presented by designers from Scotland.

The principle of operation of the system of Scottish designers and researchers from Australia is different. The installation of Scottish designers does not use the holographic principle. In addition, the installation itself is large and it is impossible to fit it into a mobile device. Researchers from Australia claim that a “graphene screen” can be equipped with a device of almost any size, up to “smart watches”. You can also find works on the creation of liquid crystal phase modulators for displaying three-dimensional images in mobile devices, but they allow you to view the image only within a few angles.
