Which bus is the longest in the world?

Since the appearance of the first models, buses have changed a lot. Now some of them, such as the world's largest articulated bus, manufactured by the Wayne Corporation, can accommodate up to two hundred passengers. "Articulated" means "consisting of two or more parts".

This design is sometimes called the "accordion bus" for the rubber tambour, something really reminiscent of the bellows of a musical instrument. So, the American accordion bus "Wayne" accommodates 187 passengers, and its length is 23 meters. This "caterpillar" weighs as much as 11 tons.

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 ... >>

Married women look younger 22.10.2016

Scientists from Denmark managed to find out why women consider marriage as one of the main goals in their lives. It turned out that being married, women retain their usual beauty and youth.

It is reported that the specialists conducted a special experiment, for the participation of which twin sisters were invited. One of the sisters was married, the other was in active search. In the course of the experiment, scientists recorded an interesting feature. The fact is that the married woman looked much younger than her sister. At the same time, experts emphasize that the married woman did not have children.

Experts explain that a married woman feels calmer and more confident than a single person. Accordingly, this is reflected in the appearance. Meanwhile, the appearance of children radically changes the appearance of a woman. The result of this is a lot of additional worries and sleepless nights. In this case, the palm belongs to single and childless ladies who have more free time to look after themselves.

At the same time, scientists remind that human genes are 60% responsible for the aging process, but the remaining 40% fall on lifestyle. Calmness and nervousness, lack of stress and depression, confidence in tomorrow and eternal worries about daily bread - all this is reflected in beauty and health.
