Formwork with a clamp. Tips for the home master

Builder, home master

When it becomes necessary to make a concrete pillar or some other vertical structural element, a wide variety of improvised means are used to fasten the formwork boards: wire, nails, all kinds of corners, staples ...

Anyone who performs such work relatively often may be interested in such a giant clamp: it will significantly save time. It is advisable to fix one of the legs of the clamp with a nut in order to be able to create a longitudinal tension if necessary.

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 ... >>

Parents smoke - children get sick 04.08.2011

Pediatricians from Heidelberg (Germany), after examining 4236 kindergarteners and the conditions in their families, came to the conclusion that children of smoking parents at the age of four or five years are often prone to hypertension.

In the surveyed families, 29% of fathers smoked, 21% of mothers smoked, and both parents smoked in 12% of families. In 20% of children exposed to tobacco smoke at home, the upper value of blood pressure turned out to be at the limit of the norm, and there is a risk that hypertension will develop in the future. In addition, children in smoking families are more likely to get colds, asthma and inflammation of the middle ear.

By the way, back in 2004, Swedish researchers found that even in cases where parents smoke only on the balcony or on the landing, the blood of children contains twice as much nicotine residues than children from non-smoking families. Obviously, nicotine gets to them through the breath of parents and their clothes.
