Where is gold produced from sewage waste?

The gold content in the ash from the burning of dry sewage sludge in the Japanese city of Suwa is more than 50 times higher than that of the best gold mines. Experts explain this fact by the fact that there are many electronics factories in the city, in the production of which gold and gold-containing alloys are widely used.

Precious metal extraction facilities are already in operation.

What are the rings of Saturn?

In 1610, the great Italian scientist Galileo Galilei, who first explored the sky with a telescope, discovered a strange feature of one of the planets of the solar system - Saturn. He saw some huge protrusions on the sides of Saturn. In 1655, Christian Huygens studied Saturn using a more powerful telescope. The picture that appeared before his eyes was so strange that he was simply afraid to tell anyone about what he saw! Therefore, he wrote down his observations in a diary using a special cipher. When later they were nevertheless read, they contained the following: "It is surrounded by a thin, flat ring, nowhere touching the planet itself, inclined to the ecliptic."

The rings of Saturn, which struck the first observers so strongly, are still one of the biggest mysteries of the solar system. As far as it is known, such a phenomenon does not exist anywhere else in the entire universe accessible to study. Of course, since the discovery made by Galileo, Saturn has been well studied by people. We know that it is the second largest planet in the solar system after Jupiter and the period of its revolution around the Sun is 29,5 years. She has 10 satellites revolving around her. The surface of the planet is hidden under an atmosphere impenetrable to telescopes. Perhaps the crust of the planet consists of minerals of various metals.

However, the main feature of Saturn is these mysterious rings. The three main rings lie in the same plane, coinciding with the plane of the planet's equator. The outer diameter of the rings is approximately 270 km. The brightest is the middle of the rings. It is separated from the outer one by a gap 000 km wide. The inner ring appears very dull.

In addition to these three, with the help of equipment installed on space satellites, several more outer, barely visible rings and one inner one, located almost at the level of clouds floating in the atmosphere of Saturn, were discovered. Saturn's rings are not solid formations, but are made up of ice-covered rock fragments that orbit the planet like small moons. Perhaps they are fragments of a satellite, which for some reason never became a single whole.

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 ... >>

California bans plastic straws 26.09.2018

California Gov. Jerry Brown has signed a bill that will allow restaurants to dispense plastic straws for soft drinks only at the request of a visitor - by default, soda will now have to be drunk directly from a glass.

California has become the first US state to introduce legal restrictions on the use of single-use straws as part of the fight against plastic pollution in the oceans. At the same time, in some cities on the west coast - for example, San Francisco and Seattle - straws for drinks are already prohibited. Similar bills are already being considered in New York and Washington, and coffee chain Starbucks and several airlines are battling straws privately.

The problem of water pollution with plastic is by no means a joke - most of the garbage ends up in water bodies, where it poses a serious danger to animals and birds. Moreover, microscopic particles and fibers of plastic, as American scientists have found out, are contained even in tap water around the world: most of them were found in water from the USA and Lebanon (94% of water samples contained plastic), as well as India (92%). The least plastic in water comes from Europe - it contained 72% of the samples.

California's straw ban will go into effect on January 1 next year and will only affect restaurants with waiters, not fast food establishments. After two warnings, the establishment will have to pay a $300 fine. Also, as part of the fight against obesity, Brown signed a law that requires that since the new year, the drink in children's meals in fast food establishments should be water or milk by default, but not sugary sodas and juices - they will also have to be requested separately.
