Why do cows chew their cud?

Many thousands of years ago, there were animals that could not protect themselves from strong and bloodthirsty enemies. They couldn't run too fast, they didn't have sharp fangs or claws. And in the process of survival, they have a special way of eating. They had to quickly grab something from the food and at the first opportunity, hastily swallowed without chewing, immediately run away. Then, already in a safe place, being in a calm state, you can chew food at your pleasure!

Our ruminants have gradually become so in the process of evolution, and therefore are called so. Note that almost all mammals useful to humans are ruminants. These are cows, sheep, goats, camels, deer, llamas, antelopes.

What allows ruminants, such as cows, to chew their cud? Such animals have a special digestive system, consisting of 5 parts. The first is a scar, then a mesh, a book, an abomasum and an intestine.

Each of these departments performs certain functions during digestion. First, food enters the largest part - the rumen, where fermentation processes take place under the influence of microflora. Then the food is in the grid, where it is formed into small balls, convenient for chewing.

They fall back into the mouth, where the animal chews them, usually resting somewhere. Finally, these balls are swallowed again and fall into the book. From here they go to the abomasum, where the assimilation process takes place. Camels, unlike other ruminants, do not have this division.

Cows do not have upper teeth. But the gum looks like a solid pad. When a cow grazes, she plucks the grass with a lateral movement of her head with the help of her lower teeth.

How fast does hair grow on your head?

Every day they lengthen by 0,3 mm, i.e., by about 1 cm per month. Hair grows constantly, from time to time we cut it (cut). Every day we lose 40-60 hairs, but new ones grow every day.

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 ... >>

Charging implants with ultrasound 23.04.2022

Various kinds of electronics have long been implanted in the human body. A typical example is a pacemaker. But when its battery runs out, the implant needs to be surgically replaced. Korean scientists have found a way to solve this problem using remote ultrasonic charging.

Although there are many wireless charging technologies in the world of electronics, the most current ones are not suitable for medical applications. So, electromagnetic induction allows you to charge the batteries of smartphones located at a distance of up to 1,5 cm from a special panel, and quite a lot of heat is released in the process, which is unacceptable when the battery is hidden in the tissues of a living organism. Another method is charging using magnetic resonance, but the equipment in this case can be affected by wireless signal sources such as Bluetooth or Wi-Fi.

With these and other limitations in mind, a team of scientists from the Korea Institute of Science and Technology (KIST) has developed an implantable generator that can be integrated into either a pacemaker or another implant. It uses the "triboelectric effect" whereby materials create an electrical charge when rubbed against each other. In the developed design, ultrasound will become the source of oscillations for friction.

Under laboratory conditions, the generator was able to provide energy with a power of 8 mW even when the generator itself and the ultrasound source were under water at a distance of up to 6 cm. It is believed that this energy is enough to power 200 LED elements or transmit a Bluetooth signal underwater. The scientists noted that this, in theory, would allow the technology to be used in developments for underwater electronics.

For a more realistic imitation of the human body, the generator was placed in a pig carcass. According to scientists, in the future the technology will be improved and will be used in implantable or deep-sea sensors - in such cases, recharging batteries is very problematic.
