The doctor who is always with you

12.01.2010

Several Danish firms have teamed up to create a multifunctional human vital sign sensor.

A small box, smaller than a matchbox, is glued with a plaster on the body and constantly measures blood pressure, blood oxygen and sugar saturation, registers body temperature and pulse rate. If these parameters go beyond the normal values, the device itself can call an ambulance through the mobile telephony network.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Growth of the precision farming market 31.10.2014

According to Marketsand Markets, between 2014 and 2020. the average annual growth rate (CAGR) of the precision farming market, which is based on Earth remote sensing (ERS) technologies, will be 12,2%. By 2020, its volume will reach $4,55 billion.

Analysts at Marketsand Markets predict that the precision farming market will reach $2020 billion by 4,55. Between 2014 and 2020. it will grow by an average of 12,2% per year.

Precision farming methods are based on land yield monitoring applications, soil monitoring technologies, crop exploration, intelligent fertilizer systems, robots, irrigation system control systems, etc.

Growing demand for food is forcing farmers to embrace new technologies such as cloud GIS, drones and satellite monitoring. This reduces costs and improves work efficiency.

The Marketsand Markets report notes that the most intensive growth of the precision farming market is expected in the Asia-Pacific region, where the population is growing most rapidly. Also, the introduction of geoinformation technologies for agriculture is actively developing in North America.

While the North American market is growing thanks to the renewal of the technological basis of agriculture, in Asia, South America and Europe strong growth is driven by the introduction of innovations in the early stages of the life cycle. In particular, the regional markets of Brazil, Argentina, some countries in Eastern Europe and China are experiencing double-digit growth due to the introduction of the latest geospatial technologies such as Farm Management Systems (FMS).

The basis for the development of the precision farming market is the desire of farmers to reduce costs and receive additional income. Government support programs that are aimed at increasing the production of strategically important food raw materials contribute to the growth of the market. At the same time, according to Marketsand Markets experts, the main problems of the market are related to the high cost of initial investments in geoinformation technologies for precision agriculture. Many farmers, already limited in funds due to the seasonal nature and high risk of doing agricultural business, have nowhere to get funds for the introduction of innovative technologies. In addition, agricultural workers often lack the information and knowledge to find, deploy and operate the systems they need.
