1400 years of man-environment interactions and soil evolution in the Saint-Mont mountain (Remiremont, Vosges)

2021

International audience; The SolHoM(a) project aims at determining the degree of landscape anthropisation in the Fossard massif (Remiremont, Vosges, France) by estimating the impact of past human occupations on current soils. Nowadays, a forest covers this relatively inhospitable mountain (hard climate, steep slopes, acid soils ...), but some remains suggest human presence for at least 1400 years.The Saint-Mont is a variscan orogenic granitic summit (height 672m) with valuable preserved archaeological relics, located south of the Fossard. At the top was founded the monasterium Habendum (from the 7th century to the French Revolution), which potentially comes after a late-antic castrum.Further…

Boosting Long-Term Stability of Pure Formamidinium Perovskite Solar Cells by Ambient Air Additive Assisted Fabrication

2021

Due to the high industrial interest for perovskite-based photovoltaic devices, there is an urgent need to fabricate them under ambient atmosphere, not limited to low relative humidity (RH) conditions. The formamidinium lead iodide (FAPI) perovskite α-black phase is not stable at room temperature and is challenging to stabilize in an ambient environment. In this work, we show that pure FAPI perovskite solar cells (PSCs) have a dramatic increase of device long-term stability when prepared under ambient air compared to FAPI PSCs made under nitrogen, both fabricated with N-methylpyrrolidone (NMP). The T80 parameter, the time in which the efficiency drops to 80% of the initial value, increases f…

Differential responses of bacterial and archaeal groups at high taxonomical ranks to soil management

2010

Little is known about abundances of the major bacterial taxa in agricultural soils and how they are affected by fertilization or other agricultural practices. Our aim was to determine the abundance and relative distribution of several bacterial phyla and one class, as well as the archaeal and crenarchaeal communities, and how they were affected by different fertilization regimes to examine whether specific responses of microorganisms could be identified at these high taxonomic ranks. We used real-time PCR with taxa specific primers to quantify the abundance of the Actinobacteria, Acidobacteria, Bacteriodetes, Firmicutes, Gemmatimonadetes, Verrucomicrobia, Alphaproteobacteria and Crenarchaeo…

Invertebrates in Fruitbodies of Heterobasidion spp., Infected Picea abies Logs and Adjacent Soil

2021

Heterobasidion spp. pathogenic fungi produce conspicuous fruitbodies on infected wood, which may represent a habitat for a range of organisms, including invertebrates. The aim was to: (i) assess and compare invertebrate diversity in Heterobasidion spp. fruitbodies, infected Picea abies wood and adjacent soil

An Original Approach to Active Climate Control Based on Equilibrium Moisture Content (EMC) as Set Point in a Middle-Age Building in Palermo, Italy

2019

In the frame of a more sustainable approach to climate control, a long term strategy has been developed and is under advanced phase of implementation by technical staff of the University of Palermo in an important building, Palazzo Steri, owned by the University. The monumental room under climate control, the Sala dei Baroni (also known as Sala Magna), has a precious wooden ceiling where the previously loadbearing elements are covered with wooden painted panels. Many of them, painted in the fourteenth c, underwent important restorations in the past due to climate related damage (cracks, warpings, paint layer delamination) and biological infestations. The room is currently undergoing an impo…

Research production in high-impact journals of contemporary neuroscience: A gender analysis

2017

Neuroscience or Neural Science is a very active and interdisciplinary field that seeks to understand the brain and the nervous system. In spite of important advances made in recent decades, women are still underrepresented in neuroscience research output as a consequence of gender inequality in science overall. This study carries out a scientometric analysis of the 30 neuroscience journals (2009–2010) with the highest impact in the Web of Science database (Thomson Reuters) in order to quantitatively examine the current contribution of women in neuroscientific production, their pattern of research collaboration, scientific content, and the analysis of scientific impact from a gender perspect…

Significant others’ experience of hospitalized patients’ transfer to home:a systematic review protocol

2014

Review question/objective The objective of this review is to identify, appraise and synthesize the best available evidence exploring significant others’ experiences of the discharge/transfer of patients after hospitalization. More specifically, the review questions are: What is the significant other(s) experience of hospital/discharge transfer of patients; in particular, experiences relating to transitions concerning organizational, psychosocial and existential issues? How do significant others experience their preparedness for bringing the patient(s) home? How do significant others experience the planning of discharge? Inclusion criteria Types of participants The participants of this revie…

The Impact of Solar Penetration on Solar and Gas Market Value: An Application to the Italian Power Market

2014

We assess the impact of solar penetration in the Italian wholesale electricity market on the market value of solar with respect to gas sources, measured as the ratio between the relative price they respectively earn and the average daily electricity price (value factor). We find that, on average, an increase of solar generation has a negative impact on the price earned by solar producers, thus causing a marginal departure from the grid parity condition. The relation between solar production and its market value is not constant over the years, while it depends on the degree of solar penetration. It is positive for very low levels of solar production while, as production increases, its margin…

Hospitalization for self-harm during the early months of the COVID-19 pandemic in France: A nationwide retrospective observational cohort study

2021

ABSTRACT Background Little is known to date about the impact of COVID-19 pandemic on self-harm. Methods The number of hospitalizations for self-harm (ICD-10 codes X60-X84) in France from 1st January to 31st August 2020 (including a two-month confinement) was compared to the same periods in 2017–2019. Statistical methods comprised Poisson regression, Cox regression and Student's t-test, plus Spearman's correlation test relating to spatial analysis of hospitalizations. Outcomes There were 53,583 self-harm hospitalizations in France during January to August 2020. Compared to the same period in 2019, this represents an overall 8·5% decrease (Relative Risk [95% Confidence Interval] = 0·91 [0·90–…
