Focus Description:

Pick up an ordinary glass, pour cold water into it, lower the boiler into the glass and turn it on. Water boils in your hand without causing harm.

Focus secret:

You can easily do this trick if you know the laws of physics. You just need to choose the right size of the glass and boiler. The boiler must not completely enter the glass, its spirals must not touch the bottom of the glass. It is best if the boiler remains about 3/4 cup. In this case, we will divide the glass into three zones. The lower part is from the bottom to the boiler. The water in it will always be the coldest.

As you know, when heated, cold water under the heater, if it is not specially mixed, will never rise up by itself, because warm water is lighter than cold water. In the boiling zone and above it, the water boils, and the glass heats up. Therefore, if you keep a glass of boiling water under the boiler, then you will never burn your hands, but to check, let's touch the top of the glass.

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 ... >>

Energy-efficient LTE modem with speeds up to 450 Mbps 06.12.2014

Qualcomm Incorporated (NASDAQ: QCOM) today announced the release of the Qualcomm Gobi 9x45 360th generation multi-mode LTE modem and the 3100nd generation Qualcomm RFXNUMX Envelope Tracker QFEXNUMX energy tracker.

Both products are designed to provide high speed data download from the network, fast application performance, as well as improve the energy efficiency of the device and optimize energy consumption. New products are currently being tested by Qualcomm partners, and deliveries to the market are scheduled for 2015.

In addition to general improvements that optimize power consumption and PCB space, the 9x45 modem is the first Category 10 solution to support carrier aggregation worldwide, providing up to 450 Mbps downlink and up to 100 Mbps uplink. c, aggregating the frequencies of the TDD and FDD spectrum.

The modem is based on the second generation 20nm process technology and provides aggregation of up to three frequencies in the 60 MHz band on the downlink and up to two frequencies in the 40 MHz band on the uplink. The 9x45 modem integrates all major cellular standards including DC-HSPA, EVDO, CDMA 1x, GSM and TD-SCDMA, supports all major RF bands and their combinations, and provides geolocation in GPS, Beidou, GLONASS and Galileo systems. In addition, the new modem supports LTE Broadcast, VoLTE and LTE Dual SIM by default.

The layout of the QFE3100 has been optimized to reduce PCB area by 30%, making the chip more energy efficient than previous generation solutions.

The use of a 9x45 modem allows mobile device manufacturers to use the maximum available private spectrum, provide high data rates and greater flexibility in implementing network architecture.

Qualcomm's new solution meets market demands for more efficient power consumption and thinner devices, bringing diversity to mobile solutions. For consumers, this means up to 6x faster upload speeds and up to XNUMXx peak download speeds compared to LTE Category XNUMX devices. In addition, the advanced modem improves application responsiveness and better connectivity to LTE-A coverage.
