This was the first study to report increased visits for symptoms of heart failure in counties exposed to wildfire smoke. The study found a 37 percent increase in emergency room visits for people with symptoms of heart failure during a three day period of dense smoke exposure and the following five days.
The EPA study also showed an increase in emergency department visits for problems relating to asthma, chronic obstructive pulmonary disease (COPD), pneumonia, and bronchitis, which are similar to studies of other wildfires.
Researchers used satellite imagery to identify counties impacted by the wildfire, and obtained numbers of emergency room visits for cardiac and respiratory problems in exposed and nearby unexposed counties to show the health impact of this fire.
This was not a unique occurrence. Each year NC experiences more than 100 wildfires and the summer of 2011 has resulted in a peat bog wildfire, which has already consumed 45,000 acres, impacting coastal and inland counties continuously since May 5.
The study findings are expected to provide relevant and important information for state and county public health officials as they consider strategies to address the adverse health effects of wildfire smoke in the general public and especially in vulnerable populations.
The study did not examine health effects from other fires such as controlled fires that are intentionally set or other fires that burn vegetation, but not peat. The findings cannot be extrapolated to non-peat related fires. Peat fires tend to burn slowly and close to the ground so that the smoke is not as easily moved upward into the atmosphere. They are also very difficult to extinguish and can last for weeks or months.
The study was published online June 27 in Environmental Health Perspectives in collaboration with researchers from the University of North Carolina at Chapel Hill, The Brody School of Medicine at East Carolina University, Pitt County Memorial Hospital and the NC Division of Public Health. The title is: Peat Bog Wildfire Smoke Exposure in Rural North Carolina is Associated with Cardiopulmonary Emergency Department Visits Assessed Through Syndromic Surveillance.

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
