Why can't you create a folder named con on Windows?

On Windows, you cannot create a folder named "con" in the usual way. Many sites claim that this is a personal desire of Bill Gates, who was teased as a child with such a word (which supposedly means "nerd"). In fact, everything is simpler: this limitation dates back to the days of the MS-DOS operating system. There, "con" along with other similar designations (prn, aux, nul) was reserved for I/O device designations, so you can't create folders with those names.

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 ... >>

Environmentally friendly vegetable oil lubricant 08.11.2012

In October, the Fraunhofer Center for the Study of Chemical Biotechnological Processes (CBP, Leuna) launched a pilot plant for the batch production of epoxides made from locally produced vegetable oil. Epoxides are chemical intermediates that are essential for the production of lubricating oils, surfactants and emulsifiers.

Until now, epoxides have been extracted mainly from petroleum, but researchers at the Fraunhofer Institute have developed a new chemical-enzymatic process that allows the production of epoxides from vegetable oils. At the same time, the process proceeds at lower temperatures and more environmentally friendly conditions, compared to the traditional "petroleum" method. In addition, mustard oils, elderberry seeds, Abyssinian cabbage and common blackhead oil can be used as raw materials. Some of these oils are by-products of the food industry and are not consumed.

The new technology makes it possible to turn plant raw materials into a useful product by chemical-enzymatic epoxidation with the help of the lipase enzyme. The main advantage of the new technology is that the enzyme is easier and more efficient to use: unlike many other chemical reactions, enzymes operate at moderate temperatures, at neutral pH values and at normal pressure. In this case, enzymes carry out epoxidation only in certain regions of the molecules, that is, without side reactions.

The new pilot plant will be able to produce batches of epoxides not 14 grams, as in the laboratory, but 70 kg each, which will make it easier and more thorough to test the new technology and determine its prospects for industrial production.

The use of vegetable raw materials to replace oil is growing every year, although so far the share of raw materials derived from oil is much larger. So, in 2009, about 14 million tons of vegetable oil and about 400 million tons of mineral oil were used for the production of chemical and technical products.
