Why does a woodpecker peck at a tree?

Most of us think when we hear a woodpecker knock on a tree that it is ruining it by chipping. But everything is just the opposite. The woodpecker helps the tree survive.

First of all, woodpeckers are birds that live in trees. They feed on trees. Beetles and insects are hidden under the bark of trees. The woodpecker gets them by scent, although they are not visible from the outside. The woodpecker punches a hole exactly where the insects are and eats them. In most cases, these insects are harmful to the tree.

How does the woodpecker get to the insects inside the tree? One reason is that the woodpecker's beak is very sharp and strong, resembling a chisel. The woodpecker has a unique language. In some species, it is twice as long as the entire head. The tongue is round in cross section, hard at the end and with tiny denticles along the edges. In the beak, the tongue is twisted like a spring. When a woodpecker takes an insect out of a tree, it can stick its tongue deep into the hollow.

The woodpecker hollows not only living trees. He uses his chisel beak to gouge holes in dead trees. The woodpecker makes a nest there. Sometimes these birds make two holes, as if an entrance and an exit. This gives woodpeckers the opportunity to escape if an uninvited guest looks into the nest.

How fast are the trains?

The French TVG from Paris to Lyon has a speed of 260 km/h. In a test flight without passengers, he reached a speed of 515 km / h.

Japanese trains are even faster. On the segment between Tokyo and Osaka, the speed of the train reaches 300 km/h.

The fastest freight trains also run in France. Fresh vegetables are delivered from Perpignan to Paris at a speed of 140 km/h.

The longest railway is the Trans-Siberian Railway with a length of 9438 km. The entire flight from Moscow to Nakhodka lasts 8 days and 4 hours. It stops at 97 stations along the way. And the longest direct railway is in Australia. For 478 km there is not a single turn.

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 ... >>

NEC has declared war on pirated batteries 29.07.2004

With the growing popularity of digital cameras and mobile phones, the number of manufacturers of "non-native" batteries that do not meet quality and safety standards has increased. As a result, according to the original developers, devices deteriorate.

NEC Electronics has introduced a new software for microcontrollers of mobile devices that determines the authenticity of batteries. According to the Japanese company, its development is the most progressive through the use of its own Cipherunicorn-5 technology.

The advantages of the technology are 5x smaller code size and 18x speed increase compared to analogues. Thus, the program can be used in any standard 8-bit microcontroller. The code written by the company's programmers will simply not allow such batteries to work. The battery is prompted for encrypted data, which, if not matched, will result in a failure to operate from the "wrong" power source.

The speedup was achieved by using a symmetric encryption key, which can be used for both encryption and decryption. The software has some protection functions against key cracking. NEC will use the program in their 8-bit 78K0/78K0S microcontrollers and sell it to other manufacturers.

In Japan, protected cameras will appear by the end of the year, and by 2007, according to NEC's plans, there will be 50 million of them. If the technology performs well, NEC will launch printers protected in this way and other peripherals that require cartridges and power supplies.
