What is the upper temperature limit at which microorganisms can live?

The vast majority of microorganisms die when heated to 50-70 degrees Celsius, at higher temperatures only the so-called thermophilic bacteria can live.

At present, such bacteria are known (discovered off the coast of Italy) living at 113 degrees; today it is an absolute record.

However, scientists suggest that the natural limit of life is 130-150 degrees (we are talking about microorganisms in an active state; when bacteria turn into spores, they can withstand even more).

 Random interesting fact from the Great Encyclopedia:

Where did sugar come from?

There are many different types of sugar. It can be found in both animals and plants. But when people talk about sugar, they usually mean sucrose, the sugar found in sugar cane or sugar beets. Today, approximately 62,5 percent of the world's sugar production comes from cane and 37,5 percent from sugar beets. Plants that tasted sweet grew in New Guinea thousands of years ago. Ancient people often fought for the possession of these plants.

Later, with the development of civilization, sugar cane stalks were exchanged for other goods, and their use expanded. In this way, merchants spread sugar throughout the islands of the Pacific Ocean in its southern part, and also brought it to Indonesia, Asia and the Philippines. Sugarcane has been known in India, probably since prehistoric times. We know for sure that in 400 BC. e. cane sugar was widespread in India.

The first Europeans to learn about sugar cane were the conquerors who came to India with Alexander the Great in 325 BC. e. It has been described as a herb that produces honey without the aid of bees. From India, sugar cane culture and sugar production spread to Persia between 500 and 700. When the Muslims from Persia conquered the Arabian Peninsula, Syria, Palestine, Egypt and the Mediterranean, they introduced the habit of eating sugar in these countries.

Sugar cane was first introduced to the United States in 1751. Jesuit missionaries brought sugar cane from Haiti to New Orleans, Louisiana. Since 1795, the industrial production of sugar began.

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 ... >>

Toshiba multifunction microcontroller with ARM Cortex-M0 core 03.09.2014

Toshiba Electronics Europe (TEE) has introduced a new product in the TX00 series of microcontrollers based on the ARM Cortex-M0 core. The TMPM037FWUG microcontroller is designed for motor control systems in equipment such as printers (conventional and multifunctional), consumer electronics, digital instruments, and industrial automation equipment.

The development of very complex motor control systems requires a range of functions from modern devices, including multiple communication channels for communicating with the main control unit and with peripheral devices, as well as interfaces for reading numerical data from sensors. In addition, you need a timer that generates pulses to control an electric motor, such as a stepper motor or a DC motor.

The microcontroller is manufactured in an LQFP64 package, which has a size of only 10x10 mm and only 64 pins with a 0,5 mm pitch. The TMPM037FWUG microcontroller contains an 8-channel 10-bit ADC and a 10-channel 16-bit timer with a programmable pulse generator.

In addition, the microcontroller integrates a 6-channel serial interface (5 channels of SIO/UART bus and 1 channel of I2C bus), which eliminates the need for an interface expansion chip and reduces production costs. The microcontroller also uses Bit Banding technology, which allows you to access and control individual bits. This can improve the efficiency of individual bits and optimize the use of a small amount of memory, consisting of 128 KB of NAND flash and 16 KB of SRAM.

By using the same ARM Cortex-M0 core as the TX03 and TX04 series, the TMPM037FWUG MCU improves development efficiency and reduces development costs by using the same development tools for medium and large systems for all these series. The M0 core is capable of operating at a maximum clock frequency of 20 MHz in the operating voltage range of 2,3-3,6 V.
