In which country are souvenirs with the slogan No kangaroos here?

Tourists often confuse Austria with Australia - therefore, the slogan "There are no kangaroos in Austria" is very popular in Austria, applied to street signs and souvenirs.

However, this confusion also occurs at a high level. Once, at a UN meeting, Austria put forward its candidacy for elections to the Security Council. One of the votes was given in favor of Australia, although it was not on the list of candidates at all. And former US President George W. Bush thanked the Australian Prime Minister in 2007 for visiting his "Austrian" contingent in Iraq.

 Random interesting fact from the Great Encyclopedia:

What causes the heart rate to change?

Each of the human heart beats lasts approximately 0,8 seconds. During the day, it makes about 100 strokes, resting after each equal interval of time. For a year, somewhere around 000 strokes are obtained. The beating of the heart is the rhythmic contraction of the heart muscle, causing blood to circulate throughout the body. Therefore, the heart rate (and pulse beats) depends on the body's need for blood supply.

A change in the heart rate can most often be observed during heavy physical work. Here's how it goes. During the work of the muscles of our body, carbon dioxide is formed. Its molecules are transported by blood within 10 seconds to one of the four chambers of the heart, called the right atrium, which contains cells that respond to the presence of this acid. They adjust the heart rate to the amount of carbon dioxide in the blood. When the muscles of the body stop working, the amount of carbon dioxide in the blood decreases, and, accordingly, the heart beats more slowly.

The activity of the heart is connected with the needs of our whole organism. Mental excitement stimulates the nervous system, and this also makes our heart beat faster. When we are depressed or fearful, other nerves are stimulated, which causes the heart to beat more slowly.

An ordinary person cannot cause a rapid heartbeat simply by an effort of will, but there were people who had the ability to do this. One person could even make the heart stop and “freeze”, so that those around them began to think that he was really dead. But then he made his heart beat like before again.

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 ... >>

SanDisk Extreme PRO CFast 2.0 500MB/s Memory Card 13.09.2014

SanDisk announced the expansion of its range of CFast 2.0 media designed for professional use. The use of cards in this series has been approved by video equipment manufacturer Arri for Alexa and Amira cameras, as well as by other well-known companies, including Hasselblad and PhaseOne.

Two cards are presented, with a capacity of 64 and 128 GB. Their read speed is the same and is 515 MB / s, but the write speed is different: for the older and younger models, it is 440 and 240 MB / s, respectively.

These speeds are more than enough to record studio quality video in 4K format.

SanDisk Extreme PRO CFast 2.0 cards will ship in October.
