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 SPARC T5 servers powered by the world's fastest microprocessors
06.04.2013
Oracle has announced the release of new models of SPARC servers. Recall that the name SPARC is formed from the first letters of the phrase Scalable Processor ARChitecture - a scalable processor architecture and reflects the use of the RISC microprocessor architecture developed in 1985 by Sun Microsystems. As you know, Oracle bought Sun in 2009.
The new SPARC T5 and M5 series servers are running Oracle Solaris. They are mid-to-high performance and are designed for database-intensive enterprise applications as well as mission-critical business applications.
The basis of the SPARC T5 servers was the processor of the same name, which Oracle calls the world's fastest microprocessor. The microprocessor with 16 cores operates at a frequency of 3,6 GHz, simultaneously executing up to 128 instruction streams. The processor configuration includes 8 MB shared L128 cache and XNUMX KB LXNUMX cache per core.
According to Oracle, SPARC T5 servers hold 17 world performance records. Thus, Oracle SPARC T5-8 is the fastest single server for Oracle Database and the fastest single server for Oracle Middleware. In terms of price and performance, it is 12 times superior to the IBM Power 780 server.
In addition to the SPARC T5-8, the list of new products includes the SPARC T5-1B server module, the SPARC T5-2, SPARC T5-4 and SPARC M5-32 servers (it uses six-core T5 processors).
The manufacturer notes the high degree of scalability of servers, which in the maximum configuration can have from 1 to 32 processor sockets, providing access to a colossal resource of performance within a single operating system, a common set of administration and virtualization tools, which makes them "ideal platforms for building clouds."
