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 ... >>
| Random news from the Archive All-electric all-terrain vehicle Bollinger B1
03.08.2017
Total electrification has come to real SUVs. The first production electric all-terrain vehicle may well be the American Bollinger B1.
Short overhangs provide the SUV with an angle of entry of 56 degrees, exit - 53. If suddenly this is not enough, there is a regular winch. Bollinger B1 is 3810 mm long, 1943 mm wide and 1867 mm high. The curb weight of the electric vehicle is 1769 kilograms, its own carrying capacity is 2767 kg, plus the mass of the towed trailer is another 2767 kg. Weight distribution - 50:50.
The four-seater SUV is capable of transforming from a station wagon to a pickup truck and vice versa. The rear seats are easily removed, the roof is disassembled, and a partition with glass is installed behind the front seats. As a result, you can carry long pipes or boards right through the car in Bollinger! But even without this, in the double version of the cabin, the car has a total trunk volume of 2690 liters.
A storage battery with a capacity of 60 and 100 kWh is hidden under the floor - at the choice of the buyer. The power reserve on one charge will be, respectively, 193 or 322 kilometers. The total power of the electric motors is 367 horsepower, and the torque is 640 Nm. The B97 accelerates from zero to 1 km/h in just 4,5 seconds and reaches a top speed of 204 km/h. Batteries can be charged in 7,3 or 12,1 hours, depending on capacity.
