Potential use of grapevine cv Askari for heavy metal phytoremediation purposes at greenhouse scale
2020
Grapevine varieties possess desirable characteristics for phytoremediation purposes. We investigated the potential of grapevine cv Askari in phytoremediation of heavy metal (HM) pollutions. In total 80 grapevine seedlings were exposed to four levels of HM stress (mild, low, moderate, and severe) in greenhouse condition during two growing years (2018 and 2019). The HM concentrations (Zn, Cu, Cd, Cr, and Pb) were subsequently determined in the soils, roots, and grapevine aboveground parts (AGPs), and then phytoextraction and phytostabilization potential assessment indices, i.e., biological absorption coefficient (BAC), bioconcentration factor (BCF), and translocation factor (TF), were calcula…
Characterization of hydrocarbon-degrading and biosurfactant-producing Pseudomonas sp. P-1 strain as a potential tool for bioremediation of petroleum-…
2014
The Pseudomonas sp. P-1 strain, isolated from heavily petroleum hydrocarbon-contaminated soil, was investigated for its capability to degrade hydrocarbons and produce a biosurfactant. The strain degraded crude oil, fractions A5 and P3 of crude oil, and hexadecane (27, 39, 27 and 13 % of hydrocarbons added to culture medium were degraded, respectively) but had no ability to degrade phenanthrene. Additionally, the presence of gene-encoding enzymes responsible for the degradation of alkanes and naphthalene in the genome of the P-1 strain was reported. Positive results of blood agar and methylene blue agar tests, as well as the presence of gene rhl, involved in the biosynthesis of rhamnolipid, …
Terrorist Masculinities: Political Masculinity between Fiction, Facts, and Their Mediation
2018
This essay proposes that terrorism manifests itself in a relation that encompasses masculinity as well as the media. The origin of this relationship is the joint performativity of gender and acts of terror. This makes terrorism an instrument of social and political change. But in order to legitimize themselves, terrorism as well as masculinity require authorization by a phantasmagorical power. Drawing on the dominance of males among terrorists, this essay will look at an early depiction of terrorism in Conrad’s The Secret Agent, a contemporary representation in Sahota’s novel Ours Are the Streets and terrorism’s real manifestation in the Paris carnage of November 2015. It will show that in…
Assessment of Bioremediation Strategies for Explosives-Contaminated Sites
2013
Large amounts of soil and water have been contaminated with energetic compounds as a result of the manufacture, storage, testing, use and disposal of munitions as well as the use of nitroaromatic and nitramines as chemical feedstock for synthesis of pesticides, herbicides, dyes, and pharmaceuticals. Historically, TNT (2 methyl-1,3,5, trinitrobenzene) has been the most widely used military explosive (Nicklin et al. 1999; Kulkarni and Chaudhari 2007b). Since TNT is toxic, mutagenic, and also highly energetic (Rosenblatt et al. 1991), TNT contamination has a serious impact on the environment and also threatens human health (Maeda et al. 2007).
Remediation Practice at a Former Missile Base in Latvia
1998
Severe environmental pollution of soil and groundwater exists in Latvia from activities that took place at former Soviet military bases. Since 1994, the former owners of these territories have retaken possession of their lands and have started to use their properties for agriculture, exploitation of forests and recreation. These activities have increased the exposure of populations to toxic substances, with subsequent effects on human health.
RAISE study protocol: a cross-sectional, multilevel, neurobiological study of resilience after individual stress exposure
2021
IntroductionThis paper describes the protocol for an ongoing project funded by the Royal Society, the Resilience After Individual Stress Exposure (RAISE) study; which aims to examine the factors and mechanisms that facilitate resilient functioning after childhood adversity (CA).Methods and analysisWe aim to recruit up to 200 participants. We will use dimension reduction techniques (principal component analysis) on standard-normally transformed individual parameters of mental health, social functioning and CA to calculate a composite measure of adaptive (ie, ‘resilient’) psychosocial functioning. To examine the neuroimmune responses to stress and their relationship with the brain and social …
Dispositifs interculturels à distance
2008
In the context of intercultural online communication, certain dimensions of ICT we might call “figures sensibles” (Boutaud 2006) can be critically useful to understand co-construction, especially when these dimensions are also constitutive of an educational context. Thus, transparency, performance and conviviality help us interpret what can be called collaborative online interaction. Dispositive memory thrives on these dimensions and completes them. It explains in part the continuity of socially constructed identity of the community in question. It is the community aspect which in our context imposes itself despite cultural differences.
Ceramic foam supported active materials for boron remediation in water
2015
Due to the narrowrange between boron necessities and toxicity in the environment, there is a high interest in the design of effective boron remediation procedures. We have previously reported a promising boron adsorptionmaterial based on the affinity of boron aqueous species for cis-diol groups that were anchored on differentmesoporous silica matrices.However, the small particle size of these systemsmakes themdifficult to be applied on real remediation situations. In this context we report herein a novel systemfor boron adsorption fromaqueous solutions inwhich the high boron affinity for functionalized mesoporousmaterials is combined with themechanical properties of ceramic foams as macrosc…
Off the grid. Touristische Idyllen der Entnetzung
2021
Abstract The article examines the relation of tourism and idyll in regard to the mediation of the tourist experience. Digital detox tourism and off grid tourism are two examples of contemporary tourism – including their respective practices and ways of promotion – that associate certain cultural stereotypes with the idyll. While digital detox tourism promises independence from the digital world, off grid tourism detaches the tourist from infrastructure and supplies. Paradoxically, the advertising of these types of ‘disconnection’ makes use of the same linked infrastructures that tourists are bound to leave behind. Thus, this article reveals the ways in which digital detox tourism and off gr…
The education power of immigrant associations in multicultural schools
2010
With this qualitative research we are trying to know the collaborative capacity and contributions that Immigrant Associations could do to the schools that form part of a social context characterised by the recent and massive arrival of immigrants of Maghrebian, Sub-Sahara, South America, European Union, and East Europe origin. The sample constituted by 55 immigrants that are members of Immigrant Associations, 16 teachers and 16 directors of schools, makes us to think about the role the Immigrant Associations could play in the education centres. The information coming out from immigrants and teachers shows up that the participation of associations, besides to do a good intercultural work and…
