MbCo in Saccharide Solid Amorphous Systems: A Combined FTIR and SAXS Study
2011
Saccharides, and in particular trehalose, are known for their efficiency in protecting biostructures against environmental stress [1], although the preservation mechanism is still debated. Experiments and simulations [2,3] on carboxy-myoglobin (MbCO) showed that the protein dynamics is highly inhibited in dry trehalose matrices, the inhibition being dependent on the water content. In these conditions, a mutual protein-matrix structural and dynamic influence is observed.Here we report a combined FTIR and SAXS study on MbCO embedded in dry amorphous matrices of trehalose and sucrose. FTIR measurements were performed at different protein/sugar ratios, focussing on the stretching band of the bo…
Online interventions to prevent mental health problems implemented in school settings: the perspectives from key stakeholders in Austria and Spain
2021
Abstract Background Schools are key settings for delivering mental illness prevention in adolescents. Data on stakeholders’ attitudes and factors relevant for the implementation of Internet-based prevention programmes are scarce. Methods Stakeholders in the school setting from Austria and Spain were consulted. Potential facilitators (e.g. teachers and school psychologists) completed an online questionnaire (N=50), policy makers (e.g. representatives of the ministry of education and health professional associations) participated in semi-structured interviews (N=9) and pupils (N=29, 14–19 years) participated in focus groups. Thematic analysis was used to identify experiences with, attitudes a…
A sustainable city environment through child safety and mobility:A challenge based on ITS?
2012
Our cities should be designed to accommodate everybody, including children. We will not move toward a more sustainable society unless we accept that children are people with transportation needs, and ‘bussing’ them around, or providing parental limousine services at all times, will not lead to sustainability. Rather, we will need to make our cities walkable for children, at least those above a certain age. Safety has two main aspects, traffic safety and personal safety (risk of assault). Besides being safe, children will also need an urban environment with reasonable mobility, where they themselves can reach destinations with reasonable effort; else they will still need to be driven. This p…
Spatial data fusion and analysis for soil characterization: a case study in a coastal basin of south-western Sicily (southern Italy)
2012
Salinization is one of the most serious problems confronting sustainable agriculture in semi-arid and arid regions. Accurate mapping of soil salinization and the associated risk represent a fundamental step in planning agricultural and remediation activities. Geostatistical analysis is very useful for soil quality assessment because it makes it possible to determine the spatial relationships between selected variables and to produce synthetic maps of spatial variation. The main objective of this paper was to map the soil salinization risk in the Delia-Nivolelli alluvial basin (south-western Sicily, southern Italy), using multivariate geostatistical techniques and a set of topographical, phy…
The effectiveness of personalized design to feed elderly people
2015
Beyond the physiological age, the elderly population is characterized by a high heterogeneity in terms of physical, psychological and sociological status (Maître et al, 2015). Regarding eating behavior, several studies have highlighted a large inter-individual variability in chemosensory abilities (i.e. the ability to perceive an odor or a taste; Sulmont-Rossé et al, 2015) and oral-heath status (i.e. dental status, salivary flow; ALIMASSENS project), as well as inter-individual variability in food preference and food intake (AUPALESENS project). However, the food offer dedicated to the elderly population, and in particular to elderly people who needs help to obtain and/or prepare food for t…
Conseqüències psicològiques i socials del fenomen del desnonament: un estudi qualitatiu
2016
espanolEl desahucio plantea problemas en la salud fisica y mental de los individuos, ademas de aumentar las desigualdades sociales. El objetivo de este estudio es ayudar a los profesionales que intervienen en esta problematica social, explorando su percepcion en relacion con este tema. Se ha llevado a cabo un estudio cualitativo, exploratorio y descriptivo. Se han desarrollado 1 Focus Group y 9 entrevistas en profundidad a profesionales «claves», regidores y politicos de Servicios de la administracion publica, tecnicos y/o trabajadores sociales y mediadores de conflictos sociales. El desalojo se percibe como un proceso de duelo, con un impacto emocional severo que afecta a la salud de la pe…
Timbral Qualities of Semantic Structures of Music.
2010
The rapid expansion of social media in music has provided the field with impressive datasets that offer insights into the semantic structures underlying everyday uses and classification of music. We hypothesize that the organization of these structures are rather directly linked with the ”qualia” of the music as sound. To explore the ways in which these structures are connected with the qualities of sounds, a semantic space was extracted from a large collection of musical tags with latent semantic and cluster analysis. The perceptual and musical properties of 19 clusters were investigated by a similarity rating task that used spliced musical excerpts representing each cluster. The resulting…
Combined effect of low-molecular-weight organic acids and creosote on phosphatase activities in sandy soil
2018
This paper assesses the impact of creosote and low-molecular-weight organic acids (LMWOAs) on the activity of acid phosphomonoesterase, alkaline phosphomonoesterase, phosphotriesterase, and inorganic pyrophosphatase in soil. The experiment was carried out on loamy sand samples with organic carbon content of 8.71 g · kg -1 , with the following variable factors: dosages of creosote: 0, 0.5%, and 2.5%; type of LMWOAs: oxalic acid, tartaric acid, and citric acid in the amount of 50 mmol · kg -1 of soil; days of experiment: 1, 7, 14, 28, 56, 112. Obtained results showed that contamination with creosote caused decrease in the activity of soil phosphatases. The observed effect did not always incre…
Dead wood profile of a semi-natural boreal forest – implications for sampling
2019
Dead wood profile of a forest is a useful tool for describing forest characteristics and assessing forest disturbance history. Nevertheless, there are few studies on dead wood profiles, including both coarse and fine dead wood, and on the effect of sampling intensity on the dead wood estimates. In a semi-natural boreal forest, we measured every dead wood item over 2 cm in diameter from 80 study plots. From eight plots, we further recorded dead wood items below 2 cm in diameter. Based on these data we constructed the full dead wood profile, i.e. the overall number of dead wood items and their distribution among different tree species, volumes of different size and decay stage categories. We …
Środowiskowe i osobowościowe uwarunkowania satysfakcji z pracy
2019
Celem artykułu jest przedstawienie i analiza badań empirycznych na temat środowiskowych i osobowościowych uwarunkowań satysfakcji z pracy.Satysfakcja z pracy może być rozumiana, jako postawa wobec pracy wyrażająca się na płaszczyźnie emocjonalnej i poznawczej. Wyniki badań wskazują, że poziom satysfakcji z pracy może być kształtowany m.in. przez poziom wynagrodzenia, percepcję atrakcyjności pracy, ogólną ocenę pracy, możliwości rozwoju zawodowego i osobistego, poziom stresu w pracy, wiek, zakres dopasowania osoba-organizacja, płeć, występowanie konfliktu ról praca-rodzina, rodzina-praca, stanowisko. Wyniki większości badań wskazują, że wyższy poziom satysfakcji z pracy jest korzystnym psych…
