cast iron cement

1 wt. parts sulfur, 2 wt. parts of ammonium chloride and 16 wt. Parts of cast iron shavings are mixed well and stored in a dry place.

Before use, mix 1 wt. into a thick paste. parts of this powder with 20 wt. including cast iron shavings with the addition of some water,

fast setting cement

A cement mortar that hardens almost instantly is obtained by mixing a dry mixture of 2-3 wt. parts of cement and 1 wt. teaspoon of sand with a 30-40 °C warm solution of 50 g of potash and 17 g of table salt in 1 liter of water.

white cement

75 g of pure exhausted chalk and 25 g of exhausted kaolin, fired to red heat, are ground and ground into a snow-white powder. This cement, alone or with the addition of a few percent of gypsum, is an excellent hydraulic lime, hardening under water. After a week, this cement has a tensile strength of 6-10 m per cm2, and after three months - 25,5 kg per cm2,

Magnesia cement

Grind and grind into a fine powder 2 wt. parts of burnt magnesia (or dolomite), the lime of which is tightly burned with 1 wt. hours of clay and a small amount of table salt. The powders are mixed thoroughly. Before use, this mixture is mixed with water and a very strong cement is obtained, which sets quickly, does not absorb water and does not cover the iron with rust.

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 ... >>

man on earth 08.02.2003

As studies by an international group of scientists have shown, now 83 percent of the land surface is under the direct influence of man. Such areas were considered to be all areas where the population density is higher than one person per square kilometer, all lands occupied by cities or given over to agriculture, strips 15 kilometers wide along roads and large rivers, 2 kilometers wide.

Along railroads and circles of the same radius around small settlements, as well as all places so lit that at night their light is visible from the satellite.
