How are holidays related to dogs?

The brightest star, Sirius, was called by the ancient Romans Canicula, which means "little dog". The period of summer heat, when Sirius became visible in the morning, was called "dies caniculares" - "dog days", whence the word "vacation" comes from.

What is written in hieroglyphs?

The word "hieroglyphs" from ancient Greek literally translates as "sacred carving". In fact, this is not quite the exact name of the ancient writing of the Egyptians. It happened because the ancient Greeks, seeing these letters for the first time, considered them sacred, made by priests.

Egyptian hieroglyphs are, in fact, perhaps the oldest writing system known to us. Some of the discovered inscriptions date back to around 3000 BC. e., and on their basis there was a written language of ancient Egypt until the XNUMXst century AD. Initially, the ancient Egyptians used a simple form of pictorial, or, as it is called, pictographic writing, similar to those used by all the primitive peoples of the world. The hieroglyphs were simply drawings, each representing a real physical object.

The sun was depicted as a disk, the moon as a crescent, water as a wavy line, a person as a figurine, and so on. However, these "cryptograms" could not depict events and processes invisible to the eye, such as, for example, thoughts, light, day, night. Thus, hieroglyphs eventually became symbols of concepts, and not just objects. The disk could mean the concept of "day", and not just the "sun" another symbol meant "turn", "change of direction". These mental signs are called ideograms.

The next stage in the development of hieroglyphs was to depict images to reflect sounds, instead of objects that really exist. For example, in English the word "bee" - "bee" can mean not only an insect, but also the sound "bi" (bee - bi :), "a leaf" - "leaf" can sound like the sound "leaf" (li: f). Together, they denote the word "Belief" - "faith." Such hieroglyphs used as sound signs are called phonograms.

The ancient Egyptians could write any word, whether it could be depicted as a drawing or not. From these phonograms, a whole series of signs arose, each of which represented only one letter. When writing, the Egyptians used consonances. For example, the English word "drink" (to drink) would be written as "drnk" (naturally, the ancient Egyptians wrote in their own language). The Egyptians, in addition, retained the use of obsolete signs in writing - ideograms, phonograms and pictograms. Over time, this made writing so difficult that the common people often could not understand it!

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 ... >>

Up to 25% of employees are prone to workaholism 18.06.2022

In the 1970s of the XX century, the American psychologist and religious preacher Wayne Edward Oates introduced the term "workaholism" into scientific use and defined it as "an obsessive or uncontrollable desire to work."

According to the International Labor Organization, about 8% of the working population works more than 12 hours a day, and American and Asian studies show that 10-25% of workers are prone to workaholism.

Germany is in the top 10 countries that suffer from workaholism more than others. Partly because of this, it boasts not only the most powerful economy in Europe, but also an extremely low unemployment rate. At the same time, Germans know how to maintain a perfect balance between work and personal life.

Research by the Hans Beckler Foundation has shown that a third of Germany's active population works "too much" and 10% tend to workaholism. The researchers looked at data from 8000 employees at German companies collected between 2017 and 2018, just before the start of the coronavirus pandemic, when there were still clear boundaries between office work and remote work.

The researchers concluded that about 9,8% of workers showed dependence and "obsessive" attitudes towards their work. 33% worked hard, but not excessively, and the majority - 54,9% were more relaxed about their work. People who were self-employed or held senior positions in companies were more likely to show signs of workaholism. 12% of managers showed signs of addiction versus 8,7% of rank-and-file employees.

People involved in agriculture or forestry, animal husbandry and horticulture were more likely to develop job dependency, while people working in the exact and natural sciences were "least susceptible" to this phenomenon.

Significant differences arise depending on the size of the company, age and gender of employees. Thus, people working in small organizations are more prone to overwork than those who work in large companies. Young people aged 15 to 25 are also more likely to show signs of workaholism, and among women, 10,8% fell into the category of addicts.

Germany's performance in terms of workaholism is almost the same as the US and Scandinavian countries.
