Rapid test to diagnose asthma

Posted by fidest press agency su giovedì, 5 dicembre 2019

Asthma is one of the most common respiratory diseases worldwide, affecting more than 235 million patients. It is often more difficult to diagnose in children than in adults. An early diagnosis is especially important for children as to prevent severe attacks of the disease. A team of researchers at the Fraunhofer Research Institution for Marine Biotechnology and Cell Technology EMB has joined forces with some high-tech companies to develop a rapid test that requires only a drop of blood to diagnose asthma. To do this, the partners use machine learning.The transition to a new energy economy is imminent. However, representatives of small communities are often unable to envision exactly what is the best solution for them due to missing resources and know-how. Solar power, photovoltaics or geothermal? What is suitable for a community and to which percentage could each technology contribute to the community’s energy needs? Are there any funding opportunities available? Researchers of the Advanced System Technology Branch of the Fraunhofer Institute for Optronics, System Technologies and Image Exploitation IOSB-AST have developed a software tool which analyzes the needs and opportunities for a special community. The optimization tool is one of the major outcomes of the project “Technological and Economic Energy Modeling – modTRAIL”. “With our project, mayors of smaller communities can learn about technical possibilities available for the transition into a new energy economy and corresponding opportunities for funding – and the information they receive is tailored specifically to their community,” says Liane Rublack, scientist at Fraunhofer IOBS-AST. “The tool uses a mixture of conventional and renewable energy sources to calculate the optimized solution for the heat and electricity generation of the community.” In four model municipalities located in the German federal state of Thuringia with fewer than ten thousand inhabitants – namely, Kahla, Werther, Neumark and Großobringen – the researchers are already testing the tool. The procedure for decision-makers in the communities is the following: At first they have to insert the name of their municipality, whereupon they receive details about the electricity and heating demand in their locality. Afterwards, they specify their preferences for future power and heating supply. What technologies would they like to use, and which ones would they prefer to rule out? There are numerous options to choose from, including solar and wind power, battery and thermal storage units, condensing oil and gas boilers, air heat pumps and geothermal heat pumps. The tool also elicits the decision-makers’ preferences regarding other factors. Is minimizing CO2 the top priority? Or are the costs of purchasing the energy more important? Based on this priorization, the software tool determines the mixture of energy and power plants. For example, this might be a combination of photovoltaic plants, battery and thermal storage systems, and combined heat and power plants. The output also includes the costs for installation and operation, the energy procurement costs, the amount of CO2 emissions, and the funding possibilities available.“With our optimization tool, we want to start the process and show the mayors of small communities the potential offered by renewable energy sources for their municipalities,” explains Rublack. The researchers from Fraunhofer IOSB-AST used standard load profiles for households as well as the time series for renewable energy sources recorded by the German Meteorological Service – in this case, by the Thuringia weather station at Erfurt-Weimar for their software tool. For communities in Thuringia with fewer than 10,000 inhabitants, the necessary data is already stored in the system. Nevertheless, the tool can also be used in other German states with the corresponding data.The developed optimization model is an integral part of the online software of the “Transformation in Rural Areas” (TRAIL) joint research project. The specific goal of the project is to motivate a large number of smaller communities to engage fully with the questions of efficient energy supply by the help of the easy-to-use optimization tool. In particular, it lowers the barriers for the communities to start, which are due to limited human and financial resources. An online software tool was developed which generates initial statements about electricity and heating consumption of the community chiefly based on publicly available GIS data and census data and further existing data-bases. Furthermore, the optimization part generates recommendations for the energy transistion procedure of the specific community.
