How are raisins made from grapes?

Raisins are small, very sweet grapes carefully dried in the sun. There are not many areas on earth where grapes are grown and raisins are produced. Because after the ripening of the grapes, a period of several weeks of hot weather without rain is necessary in order to be able to dry it. Such areas are part of the Mediterranean in Spain and Greece, the peninsula of Asia Minor, part of South Australia, where the necessary climate exists.

San Joaquin and the Sacramento Mountain Valley are ideal areas for producing raisins and supplying them to the world market. The dry season is from August to November. There is no rain, the weather is hot, and the nearby mountains are a source of water for irrigation for the entire period of grape ripening.

In California, grapes ripen in August. It is harvested from the branches and placed on trays between rows for 23 weeks. Then it is put into boxes and dried a little more. After that, the grapes are sent to packaging plants. Here the grapes enter the conveyor to go through all the processes that prepare them for delivery to the market. Special machines remove twigs and debris. Then the grapes are washed, dried and treated with special solutions, the external moisture evaporates again, and the product is packaged in bags.

In the manufacture of raisins, about 3/4 of the original weight of the grapes is lost. Seedless raisins are obtained from the kishmish grape variety. This grape is native to California.

What does tiger skin look like?

Shaving a tiger leaves its skin striped. True, not due to their own pigmentation, but because of the hair follicles remaining under the surface of the skin, like the apparent darkening of the cheeks of clean-shaven men by the end of the working day.

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

Coffee Mysteries 05.02.2004

The caffeine found in coffee, tea, kola nut, and chocolate is generally thought to raise blood pressure.

Hypertensive patients are allowed only decaffeinated coffee. However, a study conducted at the University of Zurich (Switzerland) showed that in reality everything is much more complicated.

Fifteen healthy volunteers drank three cups of coffee each, receiving 250 milligrams of caffeine. For those who rarely drink coffee, systolic pressure increased by an average of 12,6 millimeters of mercury after an hour. And those who regularly consume this drink, the pressure remained unchanged. But what is most interesting: the participants of the experiment, who were unaccustomed to coffee, who received three cups of decaffeinated coffee, also increased their blood pressure - by 12 millimeters.

Moreover, when caffeine-accustomed subjects were injected with the substance directly into their bloodstream, their blood pressure rose as well. The only conclusion reached by the experimenters is that coffee contains many other substances that strongly influence the effect of caffeine.
