However, the incidence of childhood pneumonia is still high in urban modern cities. Which home risk factors affect the incidence of childhood pneumonia in modern urban apartment? Professor Hua QIAN and his group from School of Energy and Environment, Southeast University set out to research this problem.
A recent study found that the risk factors in indoor environment typical of modern apartments in China related to pneumonia among children. Their work, entitled "Home risk factors for childhood pneumonia in Nanjing, China", was published in CHINESE SCIENCE Bulletin.2013, Vol 58.
The study is part of the China, Child, Home, and Health (CCHH) project, which is investigating associations between home indoor environmental factors and children's health. This is a population-based cross-sectional study. The survey was performed and completed from December 2010 to March 2011 in Nanjing. Twenty-three kindergartens were randomly selected in the 11 districts. No kindergartens were selected in the 2 counties. Total 6461 questionnaires were distributed and 4014 properly filled-out questionnaires were returned, giving a response rate of 65.7%. The response rate was 61.8%, 68.4% and 82.0% for kindergartens in urban, suburban, and industrial areas respectively.
Statistical analysis was conducted using SPSS for Windows. Binary logistic models were used to test associations between home environmental exposure, building characteristics, life style and the risk of pneumonia infections. For those factors that reached significance in binary analysis, a multivariate logistic model was applied to calculate adjusted odds ratios for pneumonia infections. Step forward elimination techniques were used in the multivariate logistic regression model.
This study investigated the association between childhood pneumonia and indoor environment factors in modern homes. The pneumonia incidence is found to be high in Nanjing. Lack of ventilation, gas as cooking fuel, dampness, new furniture, "modern" floor and wall covering materials showed significant associations with the incidence of pneumonia. Other factors such as family allergy, child care by non-parents, other respiratory diseases were also reported to be associated with pneumonia. In summary, modern life style and home environment play an important role in developing pneumonia infections among children in Nanjing.
This work was supported by the National Natural Science Foundation of China (51008063). This research will make contributions towards how to prevent pneumonia infection in children. In addition, it has important scientific references when the parents choose indoor decoration materials, living environment and so on.

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...
