objective(s): the development of reliable and ecofriendly process for the synthesis of nano-metals is an important aspect in the field of nanotechnology. nano-metals are a special group of materials with broad area of applications. materials and methods: in this study, extracellular synthesis of silver nanoparticles (snps) performed by use of the gram positive soil streptomycetes. streptomycete...

to enhance solubility and the performance of a plant gum (from south peach tree of china, sp gum) as a drilling fluid additive, we explored the potential of modified sp (msp) gum by modifying it with epichlorohydrin. the modification conditions, such as the mass ratio of  the crosslinking agent, ph and temperature, were optimized and the results show that 56.40 g/100g mass ratio of the crosslin...

Eco-driving is an initiative driving behavior which aims to reduce fuel consumption and emissions from automobiles. Recently, it has attracted increasing interests and has been adopted by many drivers in Australia. Although many of the studies have revealed considerable benefits in terms of fuel consumption and emissions after utilising eco-driving, most of the literature investigated eco-drivi...

Planning and construction are well-known practical topics; however, eco-city developments and their sustainable effects on the city are less known. Xi’an is a typical city that has a target to become an eco-city. This city is selected in this case study with the aims of (1) framing eco-practices to enhance the understanding of an eco-city development and (2) evaluating the effect of eco-practic...

The Evidence & Conclusion Ontology (ECO) is a community standard for summarizing evidence in scientific research in a controlled, structured way. Annotations at the world's most frequented biological databases (e.g. model organisms, UniProt, Gene Ontology) are supported using ECO terms. ECO describes evidence derived from experimental and computational methods, author statements curated from th...

Recently it has been reported that a cathepsin B inhibitor, CA-074Me, attenuates ecotropic murine leukemia virus (Eco-MLV) infection in NIH3T3 cells, suggesting that cathepsin B is required for the Eco-MLV infection. However, cathepsin B activity was negative or extremely low in NIH3T3 cells. How did CA-074Me attenuate the Eco-MLV infection? The CA-074Me treatment of NIH3T3 cells inhibited cath...

Ecological environment quality comprehensive evaluation evaluate different cells’ ecological environment quality, on the basis of region eco-environment investigation , the indexes and math methods selected according to the region, to discover the problems and put forward comprehensive father measures. In electronic government spatial decision-making assistant systems, Estimate the region’s eco...

The virtual eco-industrial park alters the Kalundborg model by allowing firms that are not in proximity with one other to exchange material flows. Bechtel Corporation Research and Development, San Francisco, has studied the Kalundborg model and numerous other eco-industrial parks (EIPs) in order to assess the viability of industrial symbiosis (IS) on a grander scale. A world leader in engineeri...

Eco-Driving Feedback Informationssysteme haben das Potenzial, auf sehr rasche und effiziente Weise zur Reduktion von Spritverbrauch und CO2 im Strassentransportwesen beizutragen. Vor allem neuere vernetzte Fahrzeuge bieten durch die zunehmende Digitalisierung der Cockpits viel Freiraum zur Gestaltung und Untersuchung von Eco-Driving Feedback. Neben klassischen „Spritverbrauchs-Tachos" findet ma...

This study seeks to address the problems of major geo-environmental hazards caused by high-intensive coal mining in China’s western eco-environment frangible area including strong mining pressure, surface subsidence, soil and water loss, and land desertification. Using the high-intensive mining at the Xiao-jihan Coal Mine, this paper investigates the compaction characteristics of aeolian sand-b...
