... 'Angelys' is a new pear variety resulting from the cross 'Doyenné d’Hiver' x 'Doyenné du Comice'. This cross is part of a large breeding programme initiated by B. Thibault and L. Hermann at the INRA Fruit Breeding Station; this programme is a half-diallel involving 12 parents, 68 progenies and 10,626 seedlings with the aim to select late maturing cultivars with long storage ability. The female par ...

Abstract:
... Among other elements of the natural environment, soil greatly influences vine behaviour and berry composition. Its influence is complex, because soil affects vine water and mineral uptake, as well as temperature in the root zone. In this research, investigations were undertaken to assess whether vine development and grape quality potentiel could be linked to specific soil types. 15 dry farmed plot ...
... Recent technical progress of social networking tools and online mapping devices enabled citizens to send, share, and manipulate digital geographic information. However, it also enabled citizens to exercise the power of mapping without learning the respective codes of ethics. In this paper, the author describes a recent online-agitated riot that occurred in France, in 2018, to demonstrate how a sin ...

Abstract:
... Disposal of high level radioactive waste in deep underground repositories has been chosen as solution by several countries. Because of the special status this type waste has in the public mind, national implementation programs typically mobilize massive R&D efforts, last decades and are subject to extremely detailed and critical social-political scrutiny. The culminating argument of each program i ...
... Excavation work carried out at Istres and Saint-Rémy-de-Provence (Provence, Southern France), in the framework of preventive archaeology, uncovered evidence of ancient gardens (13/14th–17th centuries), equipped with lined wells. Significant numbers of waterlogged remains of fruit species as well as legumes and condiments provided information on the availability of “healthy” foods to complement and ...

Abstract:
... Soil structure is a key characteristic of soil functioning. More, silt and clay-sized organo-mineral fractions are usually considered as the most reactive soil fractions. As transmission electronic microscopy (TEM) appeared to be well-suited to study soil microstructures, it was used to test the sensitivity of micro-aggregates to land use and cultivation practices. The aims of this study were ther ...
... The hundred year history of East Malling Research Station (EMRS) is reviewed from a personal perspective: In March 1913, Kent fruit farmers in the Southeast of England founded the Wye College Fruit Experimental Station. In 1920, the newly formed ‘Kent Incorporated Society for the Promotion of Experiments in Horticulture’ took over East Malling (as a site independent from Wye College) „with offices ...

Abstract:
... 2020 marked the 10th anniversary of the Xynthia storm that hit Western Europe at the end of February 2010. In France it triggered an unprecedented coastal flooding event, with most human and material damage concentrated on the Atlantic coast in the Vendée and Charente Maritime region. A range of reforms and measures followed to manage the risk of coastal flooding at the local and national levels. ...

Abstract:
... We previously demonstrated the success of in vitro embryo production (IVP) in Lidia breed cattle (Gamarra Lazo et al. 2017 Reprod. Fertil. Dev. 30, 187). As in other species, the success of IVP is linked to the birth of calves from this technique. In the Lidia breed, an important factor to consider is the use of Lidia recipients in order to keep the temperament characteristic of this breed to next ...
... Iodine-129 has been used as a powerful tool for environmental tracing of human nuclear activities. In this work, a sediment core collected from Jiaozhou Bay, the east coast of China, in 2002 was analyzed for 129I to investigate the influence of human nuclear activities in this region. Significantly enhanced 129I level was observed in upper 70 cm of the sediment core, with peak values in the layer ...

Abstract:
... The reduction of the generation gap has become of main interest in the race for the genetic improvement of cattle and in reducing the environmental impact of dairy farms. Sexual precocity of high genetic merit heifers is therefore essential, as it allows the development of their potential as soon as possible thanks to embryo collection. Many factors influence the sexual precocity and embryos produ ...

Abstract:
... This paper critically assesses the use of radiocarbon dates as demographic proxies for population dynamics during the Mesolithic–Neolithic transition in northwest Europe. Using data from Belgium and northeast France, the impact of biasing factors such as intersite and interregional differences in research intensity (frequency and scale of excavations) and focus (dating programs, thematic foci), si ...

Abstract:
... The solution selected by some countries to isolate radioactive wastes from the biosphere for up to one million years in deep geological repositories includes a multi-barrier disposal design, with steel canister, bentonite and cement materials. The geochemical contrast between such materials and the host rock formation creates perturbations potentially altering the confinement properties of the for ...
... Foredunes are efficient natural coastal defenses acting as protective barriers during storm events. They also have the capacity to be an ecosystem hosting significant biodiversity. The economic development and/or recreational use of the foredune commonly results in a modification of natural functioning and the concomitant mixing of natural and anthropogenic processes. While the impact of human int ...
... Many studies have shown that intensive agricultural practices significantly increase the nitrogen concentration of stream surface waters, but it remains difficult to identify, quantify, and differentiate between terrestrial and in‐stream sources or sinks of nitrogen, and rates of transformation. In this study we used the δ¹⁵N‐NO₃ signature in a watershed dominated by agriculture as an integrating ...

Abstract:
... Gastrointestinal disturbances are a side-effect frequently associated with haematological malignancies due to the intensive cytotoxic treatment given in connection with bone marrow transplantation (BMT). However, intestinal microbiota changes during chemotherapy remain poorly described, probably due to the use of culture-based and low-resolution molecular methods in previous studies. The objective ...
... To gain an in-depth insight into the diversity and the distribution of genes under the particular evolutionary pressure of an arsenic-rich acid mine drainage (AMD), the genes involved in bacterial arsenic detoxification (arsB, ACR3) and arsenite oxidation (aioA) were investigated in sediment from Carnoulès (France), in parallel to the diversity and global distribution of the metabolically active b ...
