Where do we get vitamins from?

Vitamins, these necessary for life in microscopic quantities of a substance, a person receives with food. Some enter the body in the form of other substances, the so-called. provitamins, and already inside the human body are converted into the vitamins he needs. Some provitamins are converted to vitamins by exposure to sunlight (for example, vitamin D).

Various vitamins are essential for normal metabolism. For example, vitamins A, B and C are involved in the formation of new cells. B vitamins - in the formation of enzymes necessary for the absorption of proteins, fats and carbohydrates.

What drug had a direct influence on the choice of the title of one of the Beatles' songs?

When The Beatles recorded the song "Lucy in the Sky with Diamonds", John Lennon attributed the origin of the song's title to the way his son Julian dubbed his drawing. However, many saw in this name a hint of the drug LSD, because it was precisely such an abbreviation that was formed from its first letters, and the BBC completely banned the song from rotation. Paul McCartney later revealed that the influence of LSD on the song is pretty obvious.

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 ... >>

Wearable electronics instead of a PC 22.07.2013

Dell is considering entering the wearable electronics market, according to the Guardian, citing Sam Burd, Dell's vice president of personal computing. "We are exploring various ideas in this area," he said.

“While such devices are quite laborious to produce and it is not yet clear how to make them truly user-friendly. However, a smart watch on your wrist is a very interesting and attractive idea,” Bird commented.

Device form factors will continue to change over the next 5 years, according to a Dell spokesperson. Demand for desktop PCs will continue, but it will be small compared to mobile devices. The put on electronics - one of the most perspective directions, consider in Dell. This opinion is shared not only by Dell, but also by Google, which in April 2013 released a trial batch of Google Glass augmented reality glasses intended for application developers. The cost of the device was $1,5 thousand.

With a tiny LCD screen placed a short distance from the eye, Google Glass is able to show the route and messages from a mobile phone to which they are connected via Bluetooth. The device belongs to the segment of wearable electronics, as it is worn on the body. Google plans to release it to the general public in 2014.

According to Juniper Research forecast, 2013 million such devices will be sold in the world in 15, which also include smart watches Sony SmartWatch, Nike FuelBand, as well as various medical sensors and devices. By 2017, the market volume, according to analysts, will increase to 70 million devices.

According to some information, "smart" watches are also being developed by Apple. In an interview at the D11 conference in May, Apple CEO Tim Cook said that the company is also interested in this area, stressing that a device worn on the wrist is more interesting from a commercial point of view, as it forces people to wear glasses. more difficult.

Dell's entry into a new market could help improve its financial performance, notes the Guardian, and better prepare for the post-PC era. Dell is the world's third largest personal computer maker, but demand has been declining lately in favor of devices in newer form factors. According to IDC, in the first quarter of 2013, PC shipments to the global market decreased by 14%, and last year - by 3%.
