How and who discovered coffee?

According to legend, this momentous discovery took place around 850 AD under the following circumstances. Once, goats grazing on the mountain slopes of the Ethiopian province of Kaffa, having eaten red berries from stunted trees, became so excited that the shepherd could not calm them down for a long time. He also tasted these berries and after a while noticed that his fatigue had disappeared. Soon they learned to make a drink from the berries.

The news of a wonderful drink that helps to maintain vigor quickly spread throughout the neighborhood. It was widely used by the monks so as not to fall asleep during many hours of prayer. The world's first coffee shop opened in 1475 in Constantinople, and in 1554 the first two coffee houses were built there.

In Europe, coffee appeared in the middle of the XVII century - first in Italy, then in France, England and other countries. The date of appearance of coffee in Russia is considered to be 1665. It was then that the court physician Samuel Collins prescribed a recipe for Tsar Alexei Mikhailovich: "Boiled coffee, known by the Persians and Turks, and common after dinner ... is a fair remedy for arrogance, runny nose and headaches."

Which country imports waste for recycling plants?

In Sweden, only 4% of garbage is buried in the ground, everything else is recycled. The government's waste burning energy program has been so effective that in recent years Sweden has been importing 80 tons of waste from other countries a year, most of it from Norway. Moreover, the Norwegians themselves pay for the removal of this waste, the Swedes receive electricity, and the remaining ashes with a high content of toxins and heavy metals are sent back to Norway for burial.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Cost-Effective Wi-Fi Chips for Consumer Electronics 22.09.2013

Qualcomm Incorporated announced that its Qualcomm Atheros division has introduced a new family of low power Wi-Fi chips. These chips will develop and support the concept of the "Internet of Things", helping to provide communication between devices of different types. With an IP stack and full on-chip network services, the QCA4002 and QCA4004 platforms will allow manufacturers to add Wi-Fi support to virtually any device without additional development costs.

The platforms are distinguished by the integration of a processor and a memory module on a chip, which eliminates the need to use a system controller, which increases the cost of the product and its power consumption. Using the QCA4004, companies will be able to build their own applications on the Qualcomm Atheros platform, rather than just using it for Wi-Fi connectivity.

The QCA4002/4004 platforms are designed for use in household appliances (washing machines, air conditioners, water heaters, etc.), consumer electronics, as well as sensors and smart sockets for household lighting, security and automation systems. The QCA4004 platform is already used in Haier's washer-dryers and split systems.

The QCA4002/4004 also uses the AllJoyn software platform to realize the IoT concept. The platform provides uninterrupted communication between different types of devices, services and services. Alljoyn helps solve universal tasks of user interaction with devices around them: registration, notifications, audio streaming and control.

Haier and Qualcomm Atheros at IFA 2013 demonstrated two devices based on the QCA4004 platform: a washer-dryer and an air conditioner. "Because Qualcomm Atheros provides turnkey Wi-Fi platforms with low power consumption, Haier has been able to quickly develop products that are ready for mass production," said Lily Li, CEO of Qingdao Haier Smart Home Technology Limited. Wi-Fi enabled devices will be in demand by consumers who want to control household appliances through mobile devices."

"By building the IoT hub, Qualcomm is building and delivering cost-effective and energy-efficient connectivity solutions. Qualcomm's new Atheros development allows many new home and office devices to connect to standard Wi-Fi networks," said Jason Zheng, senior vice president of Qualcomm Atheros - The QCA4002 and QCA4004 platforms reduce power consumption and eliminate the use of main processors, which simplifies installation, configuration and operation."

Both the QCA4002 and QCA4004 platforms include a Green TX feature that can reduce data transmission power by up to half when there are access points or other devices nearby.

Dynamic power control and sleep function, when consuming less than 1 mW, improve communication efficiency and battery life: for example, in remote controls, thermostats and sensors. A special program is responsible for reducing the power consumption on the platform, which controls the automatic wake-up or transition to sleep mode, in which the power consumption can be reduced to microamps. At the same time, the QCA4002 and QCA4004 wake up from sleep mode four times faster than their counterparts.
