Why is the Michelin Bibendum tire symbol white and not black?

Initially, car tires were white or beige, and only in 1912 they acquired the black color we are used to, as manufacturers began to add carbon to the rubber base as a preservative and stabilizing element. That is why Bibendum - one of the world's oldest trademarks, a symbol of Michelin since the late 19th century - is white, not black.

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 ... >>

Ancient mines and modern ecology 04.03.2002

Ecologists say that the inhabitants of the Earth are still being adversely affected by toxic substances that were produced in ancient mines and smelters two thousand years ago.

Even now, wind-blown microparticles of heavy metals retain high concentrations and are absorbed by plants, animals and people inhabiting the areas of ancient mine workings, says Brian Pyatt from the University of Nottingham, England. Having studied the processes of environmental pollution in the Wadi Fainan area in southern Jordan, measuring the current concentrations of copper and lead in this arid region, where the Babylonians, Assyrians, Romans and Byzantines were mining thousands of years ago, the scientist found that these concentrations are exceptionally high today, despite the long-term effect of water and wind erosion, and pose a great threat to the health of the Bedouins, causing nausea, diarrhea, convulsions, and even causing death.

Due to the ancient mining industry, today's nomads of the area suffer from gastrointestinal and respiratory diseases, chronic fatigue, paralysis and mental disorders.

This phenomenon is not unique to the Middle East. For example, the Tamar Valley in the southwest of England is still poisoned by the products of mine workings at the end of the century before last.
