Impact of silicates and detergents on primary production and total biomass of algae in a short-term laboratory experiment

Changes in biomechanics of skiing at maximal velocity caused by simulated 20 km skiing race using V2 skating technique
2018
This study investigated how the fatigue caused by a 20-km simulated skating cross-country skiing race on snow affects the final spurt performance from a biomechanical perspective. Subjects performed a 100-m maximal skiing trial before and at the end of the simulated race. Cycle characteristics, ground reaction forces from skis and poles, and muscle activity from eight muscles were recorded during each trial. Results showed that subjects were in a fatigued state after the simulated race manifested by 11.6% lower skiing speed (P<.01). The lower skiing speed was related to an 8.0% decrease in cycle rate (P<.01), whereas cycle length was slightly decreased (tendency). In temporal patterns, rela…

In actinomycetes, antibiotic production is often associated with a morpho-physiological differentiation program that is regulated by complex molecular and metabolic networks. Many aspects of these regulatory circuits have been already elucidated and many others still deserve further investigations. In this regard, the possible role of many small open reading frames (smORFs) in actinomycete morpho-physiological differentiation is still elusive. In Streptomyces coelicolor, inactivation of the smORF trpM (SCO2038) – whose product modulates L-tryptophan biosynthesis – impairs production of antibiotics and morphological differentiation. Indeed, it was demonstrated that TrpM is able to interact w…
A Feasibility Study for the Transition to Electric Mobility in the Island of Favignana
2021
The energy transition and climate neutrality are a short time scenario as climate concerns are rising fast. Small islands are natural microgrids in which the energy transition is subjected to economic and regulatory constraints and highly challenged by technical issues. As a first step, the Mediterranean island of Favignana has been considered in this study, to assess how electric mobility could impact the power system. According to the plans from the local decision makers, the island is moving towards a full public electric mobility in the near term, also due to the participation in the BloRin project. For this reason, a feasibility study about the technical and environmental impact of ele…

Impact des modes de production économes en pesticides de synthèse sur la qualité microbiologique des sols viticoles
2022
La viticulture est un secteur d‘activité agricole stratégique pour la France carelle représente le 1er poste exportateur du secteur agroalimentaire pourseulement 3% de la SAU Française. Toutefois, elle est aussi une forteconsommatrice de produits phytosanitaires avec 20% des pesticides utilisés enFrance à elle seule, couplé aussi a une forte mécanisation. Tout ceci entraîne unedégradation de la qualité des sols, qu’elle soit physique (Quiquerez et al., 2008),ou biologique (Dequiedt et al., 2011). Une baisse importante de la biodiversitédu sol altère ses grandes fonctions d’intérêts telles que la décomposition de lamatière organique et la fourniture d’éléments minéraux, l’effet barrière auxp…
Potential for adaptation to climate change: family-level variation in fitness-related traits and their responses to heat waves in a snail population.
2017
Background On-going global climate change poses a serious threat for natural populations unless they are able to evolutionarily adapt to changing environmental conditions (e.g. increasing average temperatures, occurrence of extreme weather events). A prerequisite for evolutionary change is within-population heritable genetic variation in traits subject to selection. In relation to climate change, mainly phenological traits as well as heat and desiccation resistance have been examined for such variation. Therefore, it is important to investigate adaptive potential under climate change conditions across a broader range of traits. This is especially true for life-history traits and defences ag…
Luokassa luokassa? : miten vanhempien status-tekijät vaikuttavat lasten toissijaiseen sosialisaatioon ja luokittumiseen ensimmäisinä kouluvuosina?
2011
Bourdieu presented his theory of class and class reproduction and I'm interested in founding out how does socialization process affect this dynamic process in an egalitarian western country. Does educational system determine the future of the children by renewing the class structure or does the equal opportunities to succeed academically invalidate the reproduction cycle. By using longitudinal Alkuportaat-data (N=2258) from years 2006-2008 a co-variate analysis and a hierarchical modelling were made. Mathematical problem-solving and fluency in mother tongue were used as indicators for successful secondary socialization. The class structure is presented by parents' socio-economic status, deg…
The Export Strategy and SMEs Employment Resilience During Slump Periods
2021
Abstract The Spanish economy was the most hit by the Great Recession. It suffered a greater decrease in the gross domestic product (GDP) (affecting especially internal demand). However, it suffered a greater increase in exports (the so-called Spanish “miracle”). Particularly, Spanish SMEs incorporation into exports has been spectacular since 2008. Further, this has coincided with a huge increase in unemployment. Therefore, our main objective is to investigate the moderating role of exports in job destruction associated with recessive contexts of domestic demand using Spanish manufacturing SMEs as a case study. We obtain for SMEs that export participation helps compensate for the decrease in…
Metoda zmian konkurencyjności Estebana - Marquillasa a specjalizacja regionu na przykładzie produkcji zwierzęcej w Polsce
2016
Analiza składników zmiany (ang. shift-share analysis) jest popularną techniką analizy gospodarek regionalnych. Mankamentem klasycznej analizy zmian strukturalnych jest to, że nie uwzględnia ona relacji pomiędzy konkurencyjnością a efektem zmian strukturalnych. Esteban - Marquillas w 1972 roku zaproponował zmianę klasycznego równania shift- share, wprowadzając kategorię homotetyczną badanego zjawiska, co pozwoliło na uwzględnienie efektu konkurencyjności oraz powiązań między poszczególnymi składowymi. Ta zmiana pozwoliła na oczyszczenie efektu zmian pozycji konkurencyjności z wpływu wszelkich lokalnych zmian strukturalnych. Celem artykułu jest przedstawienie analizy składników zmiany i możli…
