Treatment of heavy petroleum hydrocarbons polluted soil leachates by ultrafiltration and oxidation for surfactant recovery

2018

Abstract Surfactant technology can improve the remediation of soils polluted by semivolatile hydrophobic contaminants, like polycyclic aromatic hydrocarbons (PAHs), by enhancing their solubility in water. However, the recovery of surfactant from soil-leachates is critical for the economic feasibility of this treatment technology. To tackle this issue, ultrafiltration (UF) and its combination with permanganate, is reported for the selective recovery of surfactant from wastewater contaminated by a complex mixture of heavy hydrocarbons mainly composed of PAHs. The overall performance of the process including the successive steps of contaminant mobilization in leachates and surfactant recovery …

Role of Hydroxyl, Superoxide, and Nitrate Radicals on the Fate of Bromide Ions in Photocatalytic TiO2 Suspensions

2020

The influence of bromide ions on systems containing highly reactive radical species is of great interest for environmental remediation, atmospheric chemistry, and the synthesis of high-added-value ...

Mediation process: increasing language awareness and developing communication skills

2014

European countries have known mediation for a long time. Notwithstanding that, various approaches and rules of mediation developed in different places all over Europe and Member States still do not have regulated mediation at all (Espluques et al. 2012). The European Union has tackled this problem with the aim to change mediation into a flexible and useful tool for the parties to solve their disputes in civil and commercial matters. The objective of this paper is to provide first a general overview of mediation process on the basis of the Directive 2008/52/EC of the European Parliament and the Council on certain aspects of mediation in civil and commercial matters. Then, attention will be f…

First principles investigations of Pd-on-Au nanostructures for trichloroethene catalytic removal from groundwater

2010

Catalytic groundwater remediation from chlorinated organic solvents like trichloroethene (TCE) has been found to be more effective and sustainable than traditional non-destructive methods. Among the experimentally studied catalyst materials, Pd-decorated Au nanoparticles show the highest activity and selectivity combined with the best resistance towards poisoning by chemicals present in groundwater. In this study the thermochemistry and adsorption geometries of TCE and its hydrodechlorination products are investigated via density functional theory calculations. Various model systems for Pd-supported Au nanoparticles are addressed. The adsorption of TCE is endothermic on bare Au(111), almost…

Acceptance of Mobile Health Apps for Disease Management Among People With Multiple Sclerosis: Web-Based Survey Study

2018

Background: Mobile health (mHealth) apps might have the potential to promote self-management of people with multiple sclerosis (MS) in everyday life. However, the uptake of MS apps remains poor, and little is known about the facilitators and barriers for their efficient utilization, such as technology acceptance. Objective: The aim of this study was to examine the acceptance of mHealth apps for disease management in the sense of behavioral intentions to use and explore determinants of utilization among people with MS based on the Unified Theory of Acceptance and Use of Technology (UTAUT). Methods: Participants for this Web-based cross-sectional study were recruited throughout Germany with t…

Impact of Mediation devices on the Museum Visit Experience and on Visitors' Behavioural Intentions

2012

This study draws on the experiential approach and has two main goals: to explore the different dimensions of the museum experience regardless of whether it is mediated by mediation devices (e.g., audio guides, interactive terminals, SmartPhones, tablets, augmented reality), and to identify the impact of such devices on visitors' behavioural intentions. The authors conduct a qualitative and exploratory investigation to address the following questions: Does the development of such devices affect both experience dimensions and the audience's behavioural intentions? Which components of a museum visit are concerned?

Combined effects of compost and Medicago sativa in recovery a PCB contaminated soil

2020

The effectiveness of adding compost and the plant Medicago sativa in improving the quality of a soil historically contaminated by polychlorinated biphenyls (PCBs) was tested in greenhouse microcosms. Plant pots, containing soil samples from an area contaminated by PCBs, were treated with the compost and the plant, separately or together. Moreover, un-treated and un-planted microcosms were used as controls. At fixed times (1, 133 and 224 days), PCBs were analysed and the structure (cell abundance, phylogenetic characterization) and functioning (cell viability, dehydrogenase activity) of the natural microbial community were also measured. The results showed the effectiveness of the compost an…

Assisted phytostabilization of soil from a former military area with mineral amendments.

2019

Abstract Due to the presence of toxic pollutants, soils in former military areas need remedial actions with environmentally friendly methods. Greenhouse experiments were conducted to investigate the aided phytostabilization of multi-heavy metals (HMs), i.e. Cd, Cr, Cu, Ni, Pb, Zn, in post-military soil by Festuca rubra and three mineral amendments (diatomite, dolomite and halloysite). The amendments were applied at 0 and 3.0% to each pot filled with 5 kg of polluted soil. After seven weeks of the phytostabilization, selected soil properties, biomass yield of F. rubra and immobilization of HMs by their accumulation in plant and redistribution among individual fractions in soil were determine…

Interacting with music mediation technology for hearing impaired - first tests with normal hearing subjects

2009

Interaction with embodied mediation technology for musical activities is a fairly young but intriguing research domain that requires building and testing of paradigms. In this paper an experimental framework is presented that has been used to test subject’s sense of embodiment in sound identification and creation. A preliminary experiment is described that is part of an ongoing series of studies set up to evaluate embodied mediation technology, test methodologies and interfaces for user-oriented approaches to embodied music cognition. Thirty-three users interacted with the embodied music interaction (EMI) tool that is prototype software implemented in-house for a real-time interactive music…
