Why do cacti go without water?

Any living creature that lives in the desert faces the problem of lack of water. Indeed, if it cannot solve this problem, it will not survive in the desert.

The cactus also needs water, but it has adapted to survive long periods of lack of rainfall accordingly. Plants growing under normal conditions consume a lot of water. Leaves take water from plant sap and then release it into the air.

The cactus does not have leaves, so it does not exude water. Its trunks are arranged in such a way that the direct rays of the sun fall on their minimum surface. Therefore, almost no moisture is released. In addition, the trunks themselves are very thick, they also retain moisture. At the same time, the stem is covered with a thick protective layer, which further protects water. The spines of the cactus also scare away thirsty animals that want to get to its moisture. Thus, some adult cacti can go without water for two years.

Cacti bloom regularly, the flowers turn into fruits that contain seeds. Most cacti have very beautiful flowers, and when they bloom, the desert takes on a bright yellow, red and purple hue, which gives them inflorescences located on polished plant stems.

There are over 1000 types of cacti. Their homeland is South and Central America, Mexico and the southwestern United States. They are very different from each other - from a small one, the size of a pincushion, which is almost invisible at the surface of the earth, to a huge cactus 10-20 meters high. This cactus is the symbol of the US state of Arizona.

The juice extracted from the stems of cacti is used in medicine and is used as a low-alcohol drink by the local population. Sweets and jams are made from the stems and fruits of cacti. Some small cacti are grown at home. Growing them in pots requires thorough drainage. The cactus must be watered every four days in summer and twice a month in winter.

How did the duel between two Englishmen end, one of whom appeared naked?

In 1806, two gentlemen, Humphrey Howarth and the Earl of Barrymore, quarreled in an English bar. A duel was scheduled the next morning, where Howarth appeared completely naked, shocking the assembled audience. Previously, he served as an army surgeon and knew that often death does not occur from the bullet itself, but from the infection brought along with a piece of clothing. The count did not want to go down in history as a man who killed a naked man in a duel, and the rivals resolved the situation amicably.

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 ... >>

NewerTech Guardian MAXimus External RAID 5TB 31.05.2014

Newer Technology (NewerTech) has released the Guardian MAXimus external storage, built around two hard drives up to 5TB each.

The drive uses 3,5-inch Toshiba MD04ACA500 hard drives with a spindle speed of 7200 rpm. These discs have a 128 MB buffer.

The hard drives are configured in a RAID 1 mirror array. This ensures high reliability: the drive works as long as at least one disk in the system is functioning. The probability of failure of two disks at once is equal to the product of the probabilities of failure of each disk, that is, much lower than the probability of failure of an individual disk.

The Guardian MAXimus has one USB 3.0, eSATA and FireWire 400 ports, as well as two FireWire 800 interfaces. The drive is compatible with computers running Windows and Mac OS X operating systems.

The maximum declared speed of reading and writing information is about 240 MB / s. The front panel has an LED status indicator.

The price of the Guardian MAXimus with two 5TB hard drives is about $780. You can also purchase a device without hard drives installed, in which case you will have to pay $120. In addition, drives with two hard drives for 1, 2, 3 and 4 TB are offered: their price varies from $260 to $620.
