Where and when did women's casual wear allow a blouse with an open chest?

In Korea during the late 17th and early 20th centuries, women wore blouses with partially or fully open breasts as everyday wear.

At that time, Koreans did not eroticize breasts, considering them only as a tool for feeding children.

What is carbon dioxide?

Carbon dioxide is a substance that usually exists in a gaseous state. It can become hard if it cools a little. The air always contains a small amount of carbon dioxide, about 1 liter in 2560 liters of air. Most of the carbon dioxide enters the air when animal and plant carbon tissues decompose. Fuels made up of carbon, such as wood or coal, produce large amounts of carbon dioxide when burned.

The human body requires a small amount of carbon dioxide to exist. It controls the speed of the heartbeat and some other bodily functions. But oversaturation of the body with carbon dioxide can cause harm and even cause death. Humans get oxygen from the air they breathe. Oxygen enters the blood. There it combines with food and turns into carbon dioxide as a result of chemical reactions. Carbon dioxide returns to the lungs and is exhaled. Trees, in turn, experience a vital need for carbon dioxide.

Green plants absorb carbon dioxide from the air through pores in their leaves. It combines with water, and then with the help of sunlight, carbon dioxide and water are converted into starch and other food for the plant. The plant releases oxygen. Plants give off oxygen and take in carbon dioxide.

Humans and animals breathe in oxygen and breathe out carbon dioxide. This maintains a constant amount of oxygen and carbon dioxide in the air. Carbon dioxide also has industrial applications, the best known of which is the carbonation of beverages.

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Implanted brain stimulator 30.04.2024

In recent years, scientific research in the field of neurotechnology has made enormous progress, opening new horizons for the treatment of various psychiatric and neurological disorders. One of the significant achievements was the creation of the smallest implanted brain stimulator, presented by a laboratory at Rice University. Called Digitally Programmable Over-brain Therapeutic (DOT), this innovative device promises to revolutionize treatments by providing more autonomy and accessibility to patients. The implant, developed in collaboration with Motif Neurotech and clinicians, introduces an innovative approach to brain stimulation. It is powered through an external transmitter using magnetoelectric power transfer, eliminating the need for wires and large batteries typical of existing technologies. This makes the procedure less invasive and provides more opportunities to improve patients' quality of life. In addition to its use in treatment, resist ... >>

The perception of time depends on what one is looking at 29.04.2024

Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time. During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up. Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time. Thus, it was shown that our perception of time is closely related to what we look at. Larger and smaller ... >>

Microplastics end up in organic fertilizers 20.04.2018

Microplastics are microscopic plastic elements that are not visible to the human eye. However, they pose an even greater danger to the environment than large plastic bottles and bags. Microplastics are now floating in all the world's oceans and end up in the food of marine life. However, on land, it can cause huge problems.

The researchers wondered if the small plastic particles that end up in uneaten food and plant waste on farms could also find their way into fertilizers. To find the answer, the scientists tested composts from several processing plants that were produced both aerobically and anaerobically.

In aerobic composting, decomposition takes place in the presence of oxygen: the waste is mixed with the soil, microbes break it down and turn it into material suitable for "feeding" plants. Anaerobic decomposition occurs in an oxygen-free environment: organic material enters either a sealed vessel or a pit, which is covered with a film, where it rots, "digests". With this method, not only fertilizers are obtained, but also biogas is produced.

As a result of the study, the scientists found some microplastics in all the samples they tested. Plastic elements were not found only in those fertilizers that were obtained from plant waste. They also found that the amount of microplastics depends on how they are recycled. More plastic microfibers end up in fertilizers obtained from aerobic composting. Experts suggest that microplastic gets into biowaste from food products (in which it is also present), as well as from plastic containers in which waste is collected and stored.

Tests were carried out at processing plants in Germany. This is a unique study because Germany is considered a country that takes organic waste management and, in general, waste sorting seriously. So, products that have long been spoiled in the refrigerator are sent to a separate wastebasket, and then to processing plants, where they are cleaned before being turned into fertilizers.
