Are there fewer rainforests on the planet?

The tropical rainforests of South America, the green lungs of our planet, covering an area of 5,2 million km², reduce their area due to logging and forest fires. Every year, 1% of these forests disappear. The global results of this situation are catastrophic.

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 ... >>

AT2AD8 High-Performance 84-Channel, 004-Bit ADC 20.03.2004

ATMEL Corporation has released a new high-performance 2-channel 8-bit ADC AT84AD004, which is a parallel processing ADC that provides performance up to 500Msps per channel and up to 1 Gsps per channel (interleaving mode - frequency division multiplexing).

The ADC contains an input multiplexer, sample/hold units that provide dynamic performance with an input signal bandwidth of 1 GHz. The typical effective number of discharges is 7.3 at 500 Msps. The ADC contains a dual demultiplexer with 1:2 or 1:1 output selection, power consumption per channel is 700mW.

The AT84AD004 is pin-to-pin and functionally compatible with the AT84AD001 and, like its predecessor, the AT84AD001, includes a 3-wire interface for offset and gain auto-calibration, a Built-in Self Test (BIST) unit, and sampling delay adjustment in frequency division multiplexing mode. ADC inputs can be configured as differential or single input, outputs have LVDS levels.

The AT84AD004 is available in an LQFP144 package in industrial and commercial temperature ranges.
