Who got the first oil?

Oil is one of the most ancient products known to man and the most widely used by him. It is rather strange that in ancient times oil was not used as food in many countries of the world! Hindus used oil as a sacrifice in religious ceremonies. The Greeks and Romans did not eat the oil either, but used it as a medicine to treat skin diseases. They believed that the soot from burnt butter was good for the eyes. The Romans used the oil as an ointment for their skin and hair.

In Spain, 300 years ago, oil was sold only in pharmacies. In ancient times, only a few people ate butter, but it was never eaten fresh. It was kept melted and there were even people who especially appreciated the century-old oil. Perhaps the manufacture of edible oil came to Europe from Scandinavia.

Today, oil is a very necessary product. This is a very high-calorie food that is quickly absorbed by the body. It also has important properties that allow the oil to stay in the stomach for a long time and provide energy to the body.

Butter production begins with the milking of cows. Since the milk of Guernsey and Jersey cows contains a lot of fat, these breeds are called "butter". After the milk is obtained, the cream is removed from it. The cream is then left at room temperature to sour. This gives them a certain taste and facilitates the oil-pressing process. The cream is pasteurized to kill all bacteria and increase the shelf life of the butter.

The butter is churned in butter mills to separate the milk fat from the whey. Whey contains no fat at all. Then water is added to the oil, and all this is again thoroughly mixed in a churn to remove all unnecessary components from the oil. After the water is removed, the oil is ready. It is passed between large rollers to make it softer and more uniform in taste and color. Now the oil is sealed and sent to the store.

Who was the first astronaut to go into outer space?

Why did man need to go into space? It is impossible not to go into space, just as, swimming, say, in the ocean, one must not be afraid to fall overboard and not learn to swim. An astronaut who goes into space must be able to perform all the necessary repair and production work, for example, to weld! .. A situation may arise when one ship must provide assistance to another.

On March 18, 1965, the flight of the Voskhod-2 spacecraft began, the commander of which was pilot-cosmonaut Pavel Ivanovich Belyaev, and the co-pilot was pilot-cosmonaut Alexei Arkhipovich Leonov. A television program was broadcast from the ship about the first spacewalk of a man, a film called "In a spacesuit over the planet" was shot.

Aleksey Arkhipovich Leonov, dressed in a soft protective suit, got out of the ship through the hatch of the airlock. Overboard, he spent 10 minutes, which showed that it is possible to work in space. At an altitude of almost five hundred kilometers above the Earth, at a speed of 28 kilometers per hour, a man flew in open space, who became a satellite of the Earth for 10 minutes.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Auxiliary chip Toshiba TC358791XBG 29.10.2014

Increasing the resolution of videos and cameras increases the amount of data in car infotainment systems. The auxiliary chip TC358791XBG, presented recently by Toshiba, is ready to take over the work with them.

The novelty supports the Gigabit Ethernet AVB standard. It provides connection of front, rear and all-round cameras, transmission of audio and video data to the head unit and displays for passengers in the rear seats. With the TC358791XBG, peripheral units can be connected to the application processor using USB 3.0, MIPI CSI-2, and DSI interfaces. The microcircuit complies with the AEC-Q100 (Grade 3) specification, which defines the reliability requirements for on-board electronics components.

In particular, TC358791XBG can split the signal on one video input into two displays connected via the LVDS interface; provide signal transmission from the head unit to several displays, serve as a receiver that allows you to connect devices with an HDMI 1.4 interface to the application processor. Other features are provided by the presence of an analog input for composite video (CVBS) and support for older cameras (matching between CVBS and LVDS).

For the external design of the TC358791XBG, an FBGA257-type package with dimensions of 15 x 15 mm was selected.

Introductory images are already available. Serial production of the manufacturer expects to begin in March next year.
