Why do swifts build nests under a canopy?

The attitude of swifts to the arrangement of their nests can hardly be described otherwise than as "disregard". How else to call the manner of construction, in which the main building material is one's own saliva, which quickly hardens in the air?

Swifts are the best flyers among birds. They live on the fly - they catch and swallow insects, quench their thirst, make dates, play weddings, relax, sleep. In the same place, in the air, they catch flying cobwebs, plant fluff, small feathers. All this is abundantly mixed with saliva and in this form is used as a building material. Swift nests are always located very high - so that they can fly up to them without interference.

Swift saliva, unlike real cement, softens and even partially dissolves in water, so almost all species of these birds nest in closed places - tree hollows, caves, grottoes - or, at least, under canopies that exclude moisture from entering nests.

Why did the female pharaoh Hatshepsut wear a beard?

The Egyptian pharaohs were considered the earthly incarnation of the god Horus and could only be male. When the female pharaoh Hatshepsut ascended the throne, for the legitimacy of her power, a legend was invented, according to which the god Amon himself descended to earth in order to conceive his daughter in the guise of Thutmose I. However, at official ceremonies, Hatshepsut was still forced to wear men's clothing and a fake beard.

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 ... >>

Plasma based water purification system 08.11.2018

Researchers at the University of Alabama at Huntsville have developed a new device that uses plasma jets and hydroxyl radicals to purify water of hard-to-remove bacteria and toxins.

Many of today's water treatment methods require the use of filters and chemicals that need regular replenishment or maintenance. At the same time, millions of people live in areas with limited access to such materials, so researchers are looking for new options for water purification using plasma. Typically, plasma water treatment is expensive, but a new class of plasma devices could change that.

Researchers at the University of Alabama at Huntsville have been studying a new type of plasma generator for water purification. The new generator supplies voltage to ionize the gas at atmospheric pressure and creates many beneficial by-products, including hydroxyl radicals, which set off a cascade of water-purifying reactions.

While the term "plasma" conjures up images of very hot solar streams moving through space, plasma-based water purification methods exploit its property to generate reactive free radicals, rendering many compounds in water inert. The plasma and subsequent chemical reactions release energy and chemicals that can kill even the microcystin that causes algae blooms lurking in our water supply.

Unlike the more common ozone-based plasma cleaners, the new device is based on the production of hydroxyl radicals. This method, scientists suggest, will bypass some of the obstacles that ozone analogues cannot, namely high energy consumption and excessive heat generation.

Using optical emission spectroscopy, the researchers compared how different factors play a role in producing more hydroxyl radicals in their plasma device. For example, increasing the voltage seems to have the greatest impact on the final result by increasing the frequency of the pulses.
