Focus Description:

The magician lowers a small piece of blue paper into an empty glass standing on the table and covers it under a cardboard cylindrical cap. The artist puts a red piece of paper of the same size between the sheets of a small notebook.

After a while, the artist lifts the cap: red paper has appeared in the glass. Then he opens the book: here lies the blue one.

Focus secret:

In a glass, prepare carbon dioxide in advance, from which the blue piece of paper will take on a red color. Before performing the trick, the glass should be covered with some kind of circle so that carbon dioxide does not mix with air.

In the book, prepare in advance a blue piece of paper of the same size as the one that you dip into the glass. On both sides of the red piece of paper that you put into the book in front of the audience, stick a small piece of wax, which will stick the piece of paper to two adjacent sheets when the book is closed.

This should be done in order not to open the book with an awkward movement in the place where this piece of paper lies or not to drop it on the floor, showing it prepared in advance.

You can get carbon dioxide in the following ways: after mixing soda with acid, pour the mixture into a deep glass. Pour a little water over this mixture so that the separation of gas is not violent. When the hissing stops, tilt this glass over another: since carbon dioxide is heavier than air, it will pour into another glass like water.

In order to prevent water from pouring out after carbon dioxide into the second glass, put some transfer paper in it. Another way: pour sulfuric acid on crushed chalk or pieces of iron, or vinegar on a crushed piece of paving stone.

In the absence of the products described above, carbon dioxide can be obtained in a simpler way, although there will be an admixture of air in it: fill the bottle with water and, plugging the hole with your finger, lower the throat down into a vessel with water. Insert one end of a curved glass tube into the throat of the bottle, take the other end into your mouth and exhale so much that all the water is forced out of the bottle. Turn the bottle upside down and seal it. If there is carbon dioxide in the vessel, then the burning match placed in it immediately goes out.

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 ... >>

Cost-Effective Toshiba ARM Processors for IoT 16.04.2015

Toshiba's new IoT processors based on ARM Cortex-A9 complement the ApP Lite TZ5000 series with low power models and provide robust security features and high memory performance.

Toshiba Electronics Europe is expanding its ApP Lite processor portfolio with the new TZ5010XBG, TZ5011XBG, TZ5021XBG and TZ5023XBG models. New processors based on ARM Cortex-A9 are designed to create solutions in the field of "Internet of Things" (IoT) and reduce power consumption.

Toshiba's hardware-assisted power management and system integration technology is said to provide high memory efficiency, low processing latency, and robust security features. The above functions allow processors to enter power saving mode within microseconds, which is much easier and faster than doing such a switch using software tools. The use of new models will reduce energy consumption and reduce heat generation in most projects. All four new TZ5000 series devices include a MIPI DSI serial display interface supporting 1080p/60 high definition video, while the TZ5010 and TZ5011 devices include a MIPI CSI2 camera serial interface supporting 1080p/30 high definition video.

The TZ5010XBG and TZ5011XBG application processors are based on a 9 GHz dual-core ARM Cortex-A1,0 processor. They also include built-in high-speed Wi-Fi 802.11ac and graphics and video processing modules with HDMI digital serial interfaces. These processors are suitable for building IoT gateways that require higher storage capacity for high-resolution media and images. Both processors have an extended operating temperature range and improved processor and memory performance. The scope of their application is expanded in comparison with previous processors and includes industrial solutions, display devices with support for Miracast, and technologies for streaming multimedia content.

The TZ5021XBG and TZ5023XBG are based on a dual-core ARM Cortex-A9 processor running at 800 MHz, support LP-DDR2/3 memory, and have a special power saving mode for use in mobile devices. All of these features are packaged in a small package, making it easy to build certain IoT devices such as smartwatches. The TZ5023XBG also contains a low power Cadence Tensilica HiFi Mini digital signal processor that processes voice, audio, and sensor signals.

Toshiba also announced the release of a general purpose reference board, software development kits (SDKs) for Android and Yocto Linux (Yocto Project), and design guidelines to easily set up the required development environment.

TZ5010XBG and TZ5011XBG are 12mm x 13mm x 1,2mm while TZ5021XBG and TZ5023XBG are only 12mm x 12mm x 0,8mm. All microcircuits have a pin pitch of 0,5 mm. Introductory samples are already available.
