What is vegetarianism?

Vegetarianism is a food system that excludes the consumption of meat of any animals. Followers of a related trend, veganism, refuse to use all animal products (animal milk, eggs, skin, fur).

The word came into use in 1842 in England. The "British Vegetarian Society" was founded (from the Latin vegetus - strong, healthy, fresh, kind).

Where are babies named after the day of the week they are born?

In the culture of the peoples of the African state of Ghana, great importance is attached to the day of the week on which a person was born - it is believed that this has an impact on his entire future destiny. Almost all children receive their first or middle name according to this day. For example, Kofi Annan, former Secretary General of the United Nations, has the name Kofi meaning "Friday". And for the popular Chelsea footballer Michael Kojo Essien, the name Kojo means "Monday".

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 ... >>

New Bluetooth 5.0 modules from STMicroelectronics 13.09.2020

The new STMicroelectronics BlueNRG-M2SA and BlueNRG-M2SP radio modules are based on the BlueNRG-2 system-on-a-chip and comply with the Bluetooth 5.0 standard. The modules support multiple roles and can act as a Bluetooth master and slave at the same time. The BlueNRG-M2 radio modules are a complete RF platform including an antenna. The Bluetooth Low Energy stack and user application can run on the module.

Modules allow you to create a complete IoT product without deep knowledge in the field of high-frequency device development and significantly reduce the time to bring a new product to market. Applications for the modules include building control devices, industrial process automation, lighting control, medical equipment and security systems.

The BlueNRG-M2 can be powered directly from a pair of AAA batteries or from any 1,7V to 3,6V power source. The BlueNRG-M2 comes in two variants: BlueNRG-M2SA and BlueNRG-M2SP. They have different internal HW configurations that differ in software initialization. The BlueNRG-M2SP module is a simplified version and does not include the 32768 Hz crystal and inductance to operate the internal SMPS power converter.

Features of BlueNRG-M2SA and BlueNRG-M2SP modules:

Bluetooth v5.0 certified;
Work in Master and Slave modes;
Simultaneous support for multiple roles;
Work with increased packet length;
Embedded ST BlueNRG-2 BLE SoC;
High performance low power MCU Cortex-M0;
Programmable built-in 256 KB Flash;
RAM 24 KB with data retention in sleep modes;
Increased output power up to +8 dBm;
Receiver sensitivity up to -88 dBm;
High radio link budget 96 dB;
Built-in BALF-NRG-02D3 balun with harmonic filter;
Interfaces 1 x UART, 1 x I2C, 1xSPI, 14xGPIO, 10-bit ADC, RTC, etc.;
Chip antenna (BLUENRG-M2SA) or PCB antenna (BLUENRG-M2SP);
Ready-made Bluetooth low energy stack in the form of a library (GAP, GATT, SM, L2CAP, LL);
BlueNRG-2 SDK with sample profiles and ready-made applications;
Built-in boot via UART-bootloader;
Small dimensions 11,5 x 13,5 mm;
Supply voltage from 1,7 to 3,6 V;
Temperature range -40...85°C.
