The use of low concentrations (optimally 2.5 to 3.5 microg/ml, depending on top agar thickness) of ampicillin in the bottom agar of the plate allows for formation of highly visible plaques of bacteriophages which otherwise form extremely small plaques or no plaques on Escherichia coli lawns. Using this method, we were able to obtain plaques of newly isolated bacteriophages, propagated after ind...

Natural treatment systems (NTS) for stormwater have the potential to provide a myriad of ecosystem services society. Realizing this requires active collaboration among engineers, ecologists and landscape planners begins with paradigm shift in communication whereby these groups are made aware each other's perceptions about NTS presence knowledge gaps that their respective disciplines can bridge....

Greening can usually have a cooling effect on urban space; but is this law also applicable to coastal sloping space? The space of Qingdao Haizhifeng Square, with topography, was the area we selected study. study contained two parts: green and residential area. ENVI-met used create six scenarios. Different lawns, black pine ash were planted in areas effect. results showed that closer sea, better...

Tall fescue (Schedonorus arundinaceus (Schreb.) Dumort.) is often managed with a cutting height ranging from 70 to 100 mm in ornamental lawns. Some autonomous mowers have been specifically designed maintain mowing the same range. Generally, operate by following random trajectories, and substantial overlapping needed obtain full coverage of working area. In case tall grass, this may cause lodgin...

The physicochemical surface properties of blastospores of the entomopathogenic fungus Paecilomyces fumosoroseus were examined. Contact angle measurements were performed on microbial lawns composed of blastospores of P. fumosoroseus to quantify their cell surface energy components. In addition, suspensions of the blastospores were characterized with the microbial adhesion to solvents assay. Zeta...

Pesticides have played very important roles against food shortages and plant diseases, and our modern life would be vastly different without their use. Weed infestation adversely affects crop production by reducing yields and decreasing market prices of the crop. For cost-effective land use, crop yield and price must be maximized, and the cost of weed control minimized. Herbicides substantially...

Abstract Ombrotrophic peatlands are important long-term sinks for atmospheric carbon as plant productivity exceeds litter decomposition. Changes in community composition may alter decomposition rates through alterations microbial communities and activity. Such driven changes however differ between microhabitats. Nevertheless, the microhabitat-context-dependency of effects on remains poorly unde...
