Photodegradation of Brilliant Green Dye by a Zinc bioMOF and Crystallographic Visualization of Resulting CO2
2021
We present a novel bio-friendly water-stable Zn-based MOF (1), derived from the natural amino acid L-serine, which was able to efficiently photodegrade water solutions of brilliant green dye in only 120 min. The total degradation was followed by UV-Vis spectroscopy and further confirmed by single-crystal X-ray crystallography, revealing the presence of CO2 within its channels. Reusability studies further demonstrate the structural and performance robustness of 1.
Le paysage, de l'information à l'élaboration d'une culture paysagère : vers des médiations paysagères au service des acteurs de l'aménagement du terr…
2005
Landscape is shaped by a community of people who do not necessarily share the same intentions and/or expectations towards landscape. Thus, the representations of the people involved (planners, decisions makers, users) influence the way landscape is being taken into consideration in the field of town-and-country-planning. The multiple representations hinder communication while projects are being discussed, yet the interlocutors are bound to come to a general agreement to guarantee an negociated-and-shared achievement. On the other hand, the minimal education about landscape is necessary to apprehend the landscaped problematics of the concerned areas; nevertheless, people usually miss the poi…

Tool use in mathematics: A framework
2015
International audience; In the course of research into the interpretation of tools in the didactics of mathematics I found both voids and conflicts. This paper presents the results of my research and a resultant statement on tool use in mathematics education. The statement incorporates constructs from several theoretical frameworks and I consider the consistency of my statement on tool use with regard to activity theory.
Performing arts and mediation technology in the period of lockdown
2021
Advancements in digital technologies have become novel ways to enrich communication, expression, and transmission of arts knowledge. Technology is increasingly implemented in the performance space, as a source of inspiration for artists. Especially in this period of lockdown, mediation technology has turned out to be an essential tool for different aspects of social life, as in performing arts. With venues, schools and artistic activities closed, performers, students and spectators have been obliged to keep connecting in remote conditions. This article wants to retrace the aesthetic impact of mediation technology in performing arts during this period of lockdown by focusing on the aspects t…
Interpersonal forgiveness and meaning in life in older adults: The mediating and moderating roles of the religious meaning system
2021
Forgiving others may play an important role in achieving meaning in life as it offers a valuable platform for deliberate moral acts of acceptance of positive affect, behaviour, and cognition towards a transgressor. The aim of this paper was to analyse the relationship between forgiveness and presence, and the search for meaning in life, as well as the mediating role of the religious meaning system in this relationship among older adults. A total of 205 older adults, 112 women and 93 men, participated in the study. The mean age was 72.59. The Transgression-Related Interpersonal Motivations Scale, the Meaning in Life Questionnaire, and the Religious Meaning System Questionnaire were employed …
Recent Developments in the Finnish Banking Sector
2000
In this paper we discuss recent developments in the Finnish banking sector. Our specific aim is to examine whether and to what extent recent developments in Finland are broadly in line with the trends common to banking sectors in Europe and also worldwide. We focus on developments in banks' profit and loss accounts, balance sheets and the market structure of the banking sector. In addition, technological developments are surveyed. As regards consolidation, the Finnish banking sector is a trendsetter. The emphasis in structural development has moved to cross-border banking and bank assurance. On the other hand, it turns out that it is difficult to track some of the trends that are believed t…
On the Ability of Perfluorohexane Sulfonate (PFHxS) Bioaccumulation by Two
2019
PFASs (perfluoroalkyl and polyfluoroalkyl substances) are highly fluorinated, aliphatic, synthetic compounds with high thermal and chemical stability as well as unique amphiphilic properties which make them ingredients in a range of industrial processes. PFASs have attracted consideration due to their persistence, toxicity and bioaccumulation tendency in the environment. Recently, attention has begun to be addressed to shorter-chain PFASs, such as perfluorohexane sulfonate [PFHxS], apparently less toxic to and more easily eliminated from lab animals. However, short-chain PFASs represent end-products from the transformation of fluorotelomers whose biotic breakdown reactions have not been ide…
Processing of metals and metalloids by actinobacteria: Cell resistance mechanisms and synthesis of metal(loid)-based nanostructures
2020
Metal(loid)s have a dual biological role as micronutrients and stress agents. A few geochemical and natural processes can cause their release in the environment, although most metal-contaminated sites derive from anthropogenic activities. Actinobacteria include high GC bacteria that inhabit a wide range of terrestrial and aquatic ecological niches, where they play essential roles in recycling or transforming organic and inorganic substances. The metal(loid) tolerance and/or resistance of several members of this phylum rely on mechanisms such as biosorption and extracellular sequestration by siderophores and extracellular polymeric substances (EPS), bioaccumulation, biotransformation, and me…
Accumulation of Pb and Zn in Bidens triplinervia and Senecio sp. spontaneous species from mine spoils in Peru and their potential use in phytoremedia…
2012
Abstract Heavy metal toxicity has become a global concern due to the ever-increasing contamination of soil, water and crops. Until recent decades little has been known about the remediation of mining sites using spontaneous plants in Latin America. Soil and plant samples were taken in Peru, at a polymetallic mine (mainly silver, lead and copper) in Cajamarca Province, Hualgayoc district. Top soils (0–20 cm) were analyzed for physical and chemical properties by standard methods. Total Pb and Zn concentrations in top soils were determined by ICP-OES. Similar metals in plants were analyzed separately (aerial and root system). Ti content was used as an indicator for contamination of plant sampl…
