The aim of this study was to assess to which extent modernisation of an aluminium production complex reduced occupational noise hazard for jobs with the highest potential of exposure. Periodical measurements of noise level were taken at the same workplaces using the same method, before and after modernisation of all plants. The results were compared with the recommended standard. After modernis...

We establish a Green-Nagdhi model equation for capillary-gravity waves in (2+1) dimensions. Through the derivation of an asymptotic equation governing short-wave dynamics, we show that this system possesses (1+1) traveling-wave solutions for almost all the values of the Bond number theta (the special case theta=1/3 is not studied). These waves become singular when their amplitude is larger than...

Plastids evolved after a cell entered a genetically different cell, followed by integration of the two genomes. Many photosynthetic cells can ingest organic particles as food, as now demonstrated in an ancestral green alga.

This paper provides a comprehensive overview of the main tax incentives used in the EU-27 member states (MSs) to promote green electricity. Sixteen MSs use tax incentives to promote green electricity simultaneously with other promotion measures, especially quota obligations and price regulation. However, not all available technologies are promoted. For example, six MSs (Germany, Romania, Slovak...

In the current design of reverse supply chain, several performance indicators must be considered and treated attentively. At this strategic level of the conception and to ensure a sustainable closed loop green supply chain, many qualitative as well quantitative criteria are taken into consideration with an environmental respect. Since the location allocation study persists as one of the most im...

Toronto has declared that every new building on its campuses will be designed to be “green-roofready”, according to Bass. “If the roof can support it and the budget is there, there are more benefits with an intensive roof. You get social benefits, and you may get even a stronger energy benefit too,” he adds. Peck agrees. Emphasizing the need to integrate green roofs into design, he says, “The r...

This study introduces a long-pass dichroic filter (LPDF) on top of a phosphor-converted LED (pc-LED) packing associated with each corresponding tunable orthosilicate ((Ba,Sr)2SiO4:Eu) phosphor in order to fabricate tunable green pc-LEDs. These LPDF-capped green pc-LEDs provide luminous efficacies between 143–173 lm/W at 60 mA in a wavelength range between 515 and 560 nm. These tunable green pc-...

Despite the fact that self-organization during friction has received relatively little attention from tribologists so far, it has the potential for the creation of self-healing and self-lubricating materials, which are important for green or environment-friendly tribology. The principles of the thermodynamics of irreversible processes and of the nonlinear theory of dynamical systems are used to...

22 In this paper we present a novel image-based approach for characterizing and classifying blue and green pigments as used in paintings based on their optical properties. Our aim is to develop a non-destructive method that can characterize and classify watercolours through a statistical approach which recognizes both the probabilistic nature of the optical watercolour information and the form ...

This article explores whether and to what extent individuals are willing to voluntarily pay a premium for products that provide public environmental benefits. In particular, we critically review and analyze the status and impacts of U.S. green power marketing to date. Green power marketing—the business of selling electricity products distinguished by their environmental attributes—seeks to deve...
