Concerns about traditional chemical pesticides has led to increasing research into novel mosquito control methods. This study compared the effectiveness of 2 different types of polystyrene beads for control of mosquito larvae in south-east Islamic Republic of Iran. Simulated field trials were done in artificial pools and field trials were carried out in 2 villages in an indigenous malaria area ...

Staphylococcus epidermidis and Staphylococcus aureus are important causative agents of hospital-acquired infections and bacteremia, likely due to their ability to form biofilms. The production of a dense exopolysaccharide (EPS) matrix enclosing the cells slows the penetration of antibiotic down, resulting in therapy failure. The EPS depolymerase (Dpo7) derived from bacteriophage vB_SepiS-phiIPL...

Insulation materials decrease the final energy consumption of buildings. In Germany, fossil and mineral insulations dominate market despite numerous life cycle assessments (LCAs) showing that bio-based can offer environmental benefits. Evaluating results such LCAs is, however, complex due to a lack comparability or costs considered. The objective this study is comparing under equal conditions i...

In this research, we developed a four-phase model, which takes the aggregate gradation and porosity into account in prediction of elastic modulus concrete, based on micromechanical theories. The model has been verified with experimental results. First, using Mori Tanaka differential self-consistent (DSC) methods, pores both mortar interfacial transition zone (ITZ) were homogenized. Then, contin...

QCD corrections to the gluino induced contribution to b → sγ are shown to be important in order to extract reliable bounds on the off-diagonal elements of the squark mass matrices. Talk presented by Tobias Hurth at the International Euroconference on High Energy Physics (EPS-HEP99), 15-21 July 1999, Tampere, Finland. Indirect Search for Supersymmetry

The uncertainties of the mean diameters of the nominal 1.0 µm SRM(®) 1690 polystyrene spheres and of the nominal 0.3 µm SRM(®) 1691 polystyrene spheres are recomputed using the current NIST Guidelines for computing uncertainty. The revised expanded uncertainty (approximately 95 % confidence level) for SRM(®) 1690 polystyrene spheres is equal to 0.005 µm compared to previous value of 0.008 µm. T...
