Why do we have moles?

There is an old belief about moles. It says that when the expectant mother is frightened or anxious before the birth of the child, the child is born with a mole on the body. And this mole supposedly has a special contour, reminiscent of what scared the mother! Well, superstition is superstition! But still, we note that there is no scientific explanation of why moles appear and how to prevent them. They are present at birth or appear shortly after birth, which is why they are called "birthmarks" or "moles".

Did you know that almost every person has at least one mole? On average, a person has 14 moles! They can appear almost anywhere, including the scalp. A mole is an overgrowth of tissue. It may consist of blood vessel tissues, pigment-containing cells, cells with a hair follicle, or connective tissue. Thus, moles can be of different origin.

There are two reasons why moles are not very desirable. One of them is the probability of its degeneration into a cancerous tumor. This is extremely rare, and most people have little cause for concern. The second reason, of course, is that moles may not look very attractive, especially if they are large and also located on the face. But since most moles never cause any major inconvenience, it's best to leave them alone. When a mole is located in a place where it can often be injured, then it is advisable to remove it. For example, moles on the soles of the feet, palms, on the neck under the collar or on the waist are constantly exposed to mechanical irritation. In such cases, it is better to eliminate them before reaching adolescence.

If the mole begins to grow, change color, peel off, itch, or bleed, you must also get rid of it. And what is very important: only a surgeon should remove moles!

Why is the UK divided into counties?

The modern division of England, Wales, Scotland and Ireland into counties is the result of a long process of historical, legislative, economic and social change over a thousand years. It began in the time of the Anglo-Saxons, when England was divided into regions, the common name of which "shire" (the Russian transcription of the word "shire") is preserved in the names of many modern counties, for example, Yorkshire, Lancashire, etc.

The division into regions stemmed from the principles of local self-government and self-defense. The Norman conquerors who conquered England in 1066 adopted this system from their predecessors.

Subsequently improved, it gradually reached the areas bordering Scotland and Wales. In Wales, the borders of the counties have changed little since the days of the Tudor dynasty, in whose veins English blood mixed with Welsh. Scotland has for centuries had a system of territories ruled by sheriffs, which was very different from the English. The division of Ireland into counties was carried out by the highest feudal nobility in the time of Henry II and further perfected by Oliver Cromwell 5 centuries later.

Over the past centuries, the map of the British counties has undergone constant changes, reflecting changes in the social life of the country. One of the most important factors causing these changes was the movement of population from one region to another, especially from the countryside to the cities during the "industrial revolution".

The largest cities, in which more people lived than in the rest of the territory of a particular county, were withdrawn from the latter in 1929 and turned into separate administrative units. It also happened that one county "swallowed" another! The creation of the Greater London Region in 1965 resulted in the former county of Middlesex being mentioned only on postal envelopes.

In some counties, two capitals appeared, one of which is a historical, and the other is an industrial, commercial and administrative center.

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 ... >>

Herbicides in capsules 08.12.2021

An innovative herbicide delivery system could revolutionize agriculture and weed control. The use of herbicide-filled capsules is safer and just as effective as the traditional method.

According to Professor Amelia Limbongan of the University of Queensland, the method was very effective against a wide range of weed species that pose a serious threat to agriculture.

"This method of weed control is practical and more convenient than other methods, and we have already seen several farms adopt this approach. The convenience of the system, combined with its proven efficacy and safety, means that the encapsulated herbicide can be used in a variety of conditions throughout The method uses 30% less herbicides to kill weeds and is as effective as more labour-intensive approaches, saving farmers and foresters time and money,” said Amelia Limbongan.

Capsulated herbicides can improve weed control in agricultural and ecological systems around the world, as well as protect workers by virtually eliminating exposure to harmful herbicides.

Professor Victor Galea noted that the herbicide capsule treatment process used a mechanical applicator called InJecta, which quickly drilled a hole in a woody weed stalk, implanted a soluble capsule containing the dry herbicide, and sealed the capsule with a wooden cork, bypassing the need to spray over large areas. . The herbicide then dissolves in the plant sap and kills the weed from within and, thanks to the small amount of active ingredient used in each capsule, does not cause the agrochemical to enter the environment.

"Another reason this delivery system is so useful is that it protects other plants that are often damaged by accidental contact when sprayed with herbicils," explains Victor Galea.

Researchers continue to test the capsule method on several different types of weeds and have a number of similar products in line for distribution that will help farmers with invasive weeds.
