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 ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Qnap TS-251A and TS-451A NAS 27.08.2016

Qnap introduced the TS-251A and TS-451A NAS, equipped with a USB QuickAccess port. In fact, this is a regular USB 3.0 Micro-B connector, with which the storage can be connected to a PC for data exchange, bypassing a wired LAN. In this mode, data exchange rates up to 100 MB / s are supported, although with the aggregation of the two available Gigabit Ethernet ports it is even higher - up to 211 MB / s.

NAS Qnap TS-251A and TS-451A received a USB QuickAccess port for direct connection to a PC
The basis of the new Qnap storages was the dual-core SoC Intel Celeron N3060, operating at up to 2,48 GHz. There are two slots for DDR3L RAM, the maximum total amount is 8 GB, and the regular one is 2 or 4 GB. Proprietary OS QTS 4.2.2 recorded on a flash drive with a capacity of 4 GB. The Qnap TS-251A and TS-451A models received two and four slots for 3,5-inch drives with a SATA 6 Gb / s interface.

Thanks to the SoC used, there is an HDMI video output with support for a resolution of 3840 x 2160 pixels (30 Hz), audio passthrough and multimedia shell control are supported using the included remote control. There are three USB 3.0 ports and an SD card reader.

It supports data encryption using the AES algorithm with a 256-bit key, virtualization of various operating systems, including Ubuntu 14.04 and 16.04, the creation of a personal cloud with file synchronization, and the launch of a video surveillance station.
