What is a sandwich made of?

One of the readers of the English popular science magazine "New Scientist" sent to the editors the wrapper from the sandwich he bought with chicken and ham.

On the wrapper, in accordance with the standard rules, the components of this double sandwich are listed:

"White bread: flour, water, yeast, vegetable fat, salt, emulsifiers (mono- and diglycerides of fatty acids, esters of mono- and diacetyltartaric acid with mono- and diglycerides of fatty acids, sodium stearoyl lactate), soy flour, calcium propionate, ascorbic acid .
Boiled chicken: chicken meat, water, modified starch, salt, milk protein, sodium polyphosphate, lactose.
Ham: pork, water, salt, dextrose, sodium polyphosphate, sodium ascorbate, sodium nitrate.
Mayonnaise: vegetable oil, water, vinegar, egg yolk, modified starch, glucose syrup, salt, mustard, stabilizers (guar gum, xanthan gum), potassium sorbate, citric acid, color (beta-carotene).
Mustard sauce: mustard, water, butter, hydrogenated vegetable oil, caseinates, stabilizer (sodium alginate), salt, emulsifier E471, whey powder, potassium sorbate, citric acid, flavors, beta-carotene, lettuce, tomato, cucumber" .

A reader asked if it could be eaten.

What is a ciliate shoe?

If you examine a drop of water from a pond under a microscope, one of the little creatures that you see will have an elongated shape, resembling a shoe: one end of it is rounded, and the other is narrowed. It is hard to believe, but this tiny creature can be classified as an animal on the basis that, like other animals, it earns its own food by eating microscopic plants and other organisms (and plants, as we know, produce their own food), and he has to move in search of food. This animal is a ciliate shoe, or paramecia. Her body is almost completely covered with thin, hair-like flagella, which we call cilia. These cilia move evenly, like thousands of small oars, causing the body to move forward, backward or in a circle.

The ciliates live in fresh water, feeding on bacteria, including yeasts, and other single-celled protozoa - small, animal-like microbes. It is likely that she is able to control the movement of cilia, as she can quickly change direction in pursuit of food or in order to avoid danger. Like all living organisms, the ciliate shoe is able to reproduce. As an adult, it can split in two and form two independent organisms. A ciliate can also reproduce by exchanging certain body particles with another ciliate.

What is remarkable about ciliates is that they are able to perform many of the vital functions that humans and large animals perform, all in a single cell, while in the human body these functions are performed by millions of cells assembled in a specific organ to perform specific functions. assignments. But there is also a certain specialization of functions in a single-celled ciliate shoe. Inside the cell there are two spherical masses, one larger than the other. These are the nuclei. The smaller nucleus performs the functions of reproduction. More - all other functions of the body.

The shoe ciliator is one of the hundreds of thousands of different types of microorganisms discovered and studied by man. (Microorganisms are too small to be examined without a strong magnifying glass or microscope). The first living things on earth were probably something like these microscopic animals.

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 ... >>

Long-lasting battery with liquid electrodes 23.09.2014

American scientists managed to develop a battery with liquid electrodes. The new battery consists of two liquid electrode layers that are separated by a liquid electrolyte layer. Since the metals and electrolyte in the battery have different densities, this prevents them from mixing.

Prior to this experiment, scientists used liquid magnesium as a substance for one electrode, antimony for the other, and saline as an electrolyte in a liquid battery. But such a device could perform its functions only at a temperature of the order of 700 ° C.

In order to lower the operating temperature of a liquid battery, scientists decided to replace magnesium with lithium, and use its alloys with lead instead of antimony. The melting point of lithium is about 180°C.

The scientists were able to select an antimony alloy that could be in a liquid state at a temperature of 327°C, providing a potential difference between the electrodes.

According to the developers, one of the advantages of liquid batteries is their high durability: liquid electrodes will not break down during a large number of charge / discharge cycles.

Scientists say that even after 10 years of daily charging and discharging, a new battery will retain about 85% of its original capacity.
