Which metropolis has no outdoor advertising at all?

In one of the largest cities in the world - Brazilian Sao Paulo - there is no outdoor advertising at all. The decision to dismantle all billboards and signs was made in 2007. According to the mayor of the city, this is one of the points of the overall campaign to combat pollution - in this case, visual pollution.

Although this law has hit the advertising industry hard, more than 70% of São Paulo residents support it wholeheartedly.

What is a quarry?

Stone quarrying is the process of extracting stone from the ground. Stones can be mined in solid blocks or slabs or crushed rubble. Blocks or slabs are used in construction. Crushed stone is used for laying roads. There are different types of quarries. In some, the stone is found in the form of a huge solid mass. In others, the stone forms layers of varying thicknesses.

A quarry is a large depression in the ground. Sometimes it is wide and shallow, and sometimes it is a deep, narrow well. The workers in the quarries have to use ladders or are lowered into the quarries by mechanical means. In quarries, water is often a problem. This is due to the fact that the quarry, like a large stone bowl, collects and stores all the rainwater that has fallen into it. In such cases, water has to be pumped out.

Sometimes the mined stone is underground. Such a quarry is called a shelf. In such a quarry, machines can go right up to the stone and tow it away. How to decide where to open a quarry? You need to do research first. Geologists can tell where a good rock is likely to be. Then you need to take a sample of the stone.

During the study, several holes are drilled in different places on the site. Special drills are used to cut out the core of the stone, about 5 cm in diameter, which is brought to the surface and examined. Some drills can penetrate up to 850 m deep. The assay indicates whether the stone is good enough to make the quarry profitable.

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 ... >>
