Where are American transport planes worshipped?

From the end of the 19th century, a cargo cult began to spread among the natives of the Melanesian islands - the belief that Western goods were sent to them by the spirits of their ancestors, and white people illegally own them.

The cult intensified after the Second World War, when the islands became a theater of operations, and manufactured goods (cargo) to supply the American army also fell to the locals.

When the war, and with it the flow of goods, ended, the natives began to build replicas of runways, airports and radio towers from wood and straw and conduct a semblance of military marches. However, this did not attract transport aircraft, and gradually the cargo cults in Melanesia faded to nothing.

Who and when discovered unicorns and winged humanoids on the moon?

In 1835, the New York newspaper The Sun published a series of essays on the discovery of life and civilization on the Moon. Allegedly, astronomer John Herschel assembled a very powerful telescope and attached a microscope to it to see fine details. As a result, he discovered unicorns, tailless beavers and winged humanoids on the moon. The publications made a real sensation and dramatically increased the circulation of the newspaper, which did not fall even after the hoax was exposed.

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 ... >>

Ion-conducting wood membranes 22.07.2021

US scientists have coated ordinary wood with a hydrogel and turned it into an ion-selective material. Membranes made of such material let only positively charged ions through, which can be used to generate electricity at the border of fresh and salt water. The results of the study are published in the journal ACS Nano.

Scientists from the University of Maryland, led by Lian Bing Hu (Liangbing Hu) managed to make ion-selective membranes from a more affordable material - wood. Wood is a composite material that consists of cellulose fibers in a matrix of the tougher lignin polymer. Wood has a porous structure, and due to negative charges on the surface, it even has some ion-selective properties - it passes predominantly positively charged ions. However, the pores in wood are too large, and the ion selectivity of wood is lower than that of artificial materials. In addition, wood is an anisotropic material, that is, its properties differ greatly depending on the direction. The conductivity is higher for porous cross-sections, and the strength is higher for longitudinal cuts (and also the area of \uXNUMXb\uXNUMXbtransverse cuts is limited by the diameter of the tree, while longitudinal cuts can have a much larger area). And finally, wood is not stable enough: with prolonged contact with water, its fibers gradually swell and the structure of the material is broken. Scientists have tried to improve the properties of wood with a polymer hydrogel coating.

The hydrogel contains carboxyl groups, which donate a proton in an aqueous medium and turn into a negatively charged COO- fragment. By covering the tree with hydrogel, the scientists intended to increase the density of negative charges on the surface of the material. And so it happened - the measurement of the zeta potential showed that the concentration of negative charges on the surface of the material almost doubled - from minus 1,49 to minus 2,53 millicoulombs per square meter. As a result, the ionic conductivity of the membranes increased by two orders of magnitude compared to untreated wood. In transverse sections, the conductivity was still higher than in longitudinal ones, but not by much - 1,29 millisiemens per centimeter compared to 0,97 millisiemens per centimeter. And hydrogel additives made the membranes stronger - the tensile strength of the longitudinal sections increased from 16,9 to 52,7 megapascals, and the transverse ones - from 1,8 to 10,7 megapascals. The authors believe that the reason is the formation of additional hydrogen bonds between cellulose fibers.

In terms of strength-conductivity ratio, the new longitudinal membranes turned out to be better than most of the known analogs. But their main advantage is low price and scalability. Wood is an inexpensive and renewable material, and the use of longitudinal cuts will make membranes of several square meters that can be used to generate energy on a large scale.
