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 Finland to deploy 5G-ready class network
22.02.2018
The Finnish telecommunications company Elisa announced its intention to deploy an advanced 5G-ready cellular network in the country by the end of the coming spring.
The project will be implemented in the oldest city of Finland - Turku, which is located in the south-west of the country at the confluence of the Aurajoki River into the Archipelago Sea.
Elisa is reported to start upgrading its existing 4G infrastructure as early as next month. The installed equipment will be replaced with a new one, ready to work with 5G services (5G-ready). It is important to note that so far there is no talk of a full-fledged launch of the fifth generation mobile network. But the company notes that in the future - with the advent of the necessary standards and obtaining licenses - the transition to 5G can be carried out in a short time and without technical difficulties.
The modernization is scheduled to be completed in May 2018. The network based on the new equipment will be able to provide increased data transfer rates based on LTE technologies, as well as improve the reliability of connections.
It is noted that the new network infrastructure will become the basis for a "smart" city. We are talking about unmanned vehicles, intelligent utilities, etc.
It should also be added that earlier Elisa began installing 5G-ready equipment in another city in Finland - Tampere, which is the second most important city center after Helsinki.
