An in vitro deletion in ribE encoding lumazine synthase contributes to nitrofurantoin resistance in **Escherichia coli** University of Antwerp
Nitrofurantoin has been used for decades for the treatment of urinary tract infections (UTIs), but clinically significant resistance in Escherichia coli is uncommon. Nitrofurantoin concentrations in the gastrointestinal tract tend to be low, which might facilitate selection of nitrofurantoin-resistant (NIT-R) strains in the gut flora. We subjected two nitrofurantoin-susceptible intestinal E. coli strains (ST540-p and ST2747-p) to increasing ...
Assembling the Full Cast: Ritual Performance, Gender Transgression and Iconographic Innovation in Viking-Age Ribe Vrije Universiteit Brussel
VIKING-AGE ICONOGRAPHY is mostly studied through stone sculpture and carvings and through metal dress accessories, which are often poorly contextualised finds. Here we present a new approach by studying an assemblage of casting moulds for figurative dress accessories from an early 9th-century workshop context in Ribe (Jutland, Denmark). We provide digital reconstructions of the fragmented moulds, including ‘Valkyrie’ pendants showing female ...
Sampling density and spatial analysis: a methodological pXRF study of the geochemistry of a Viking-Age house in Ribe, Denmark Vrije Universiteit Brussel
This study explores the significance of spatial sampling resolution on portable X-ray fluorescence (pXRF) analysis of an
archaeological settlement site with favorable preservation conditions and clearly defined stratigraphic contexts as a benchmark
study to interpret geochemical mapping of anthropogenic elemental markers. We present geochemical elemental mapping of a
Viking-Age house floor in Denmark based on an ...

Study of bound states in 10Be by one neutron removal reactions of 11Be KU Leuven
The bound states of 10Be have been studied by removing single neutrons from 11Be nuclei. A 2.8 MeV u–1 beam of 11Be was produced at ISOLDE, CERN and directed on to both proton and deuteron targets inducing one-neutron removal reactions. Charged particles were detected to identify the two reaction channels (d, t) and (p, d), and the individual states in 10Be were identified by gamma detection. All bound states but one were populated and ...
Deeper tillage and root growth in annual rice-upland cropping systems result in improved rice yield and economic profit relative to rice monoculture Ghent University
Crop rotation sequencing to minimise yield losses of summer-irrigated lowland rice in Myanmar caused by the rice root-knot nematode Meloidogyne graminicola KU Leuven
The effect of different rice-based crop rotation sequences on the population densities of Meloidogyne graminicola and on the yield of rice was evaluated in a microplot experiment under lowland rice field conditions. Ten treatments of cropping sequences were grown in four successive growing seasons: continuous growing of the susceptible rice cultivar Thihtatyin (rice-rice-rice-rice), four treatments of 1- season crop rotation sequences ...
Study on bacteria associated with rice roots and their potential to promote rice growth KU Leuven
The increasing world population demands a considerable increase in stable crop yield to assure the food supply. When rice is considered, this means an increase in rice production up to 1 billion tonnes by 2025. To boost the crop yield, chemical fertilizers, and especially nitrogen (N), are applied in tremendous amounts. However, this common agricultural practice can have a significant adverse impact on the environment. Therefore, countless ...
Influence of crop rotation on the composition of the microbial community colonizing rice straw residues in paddy rice soil in the Mekong river delta of Vietnam KU Leuven
The Mekong Delta of Vietnam is extremely suitable for rice production and continuous rice cultivation is the dominant cropping pattern (Xuan, 1992). With time, many different cultivation approaches, such as irrigation, drainage, minimum or zero tillage, inorganic fertilizer and pesticides application, burning and other approaches have been applied. Among these practices, the present intensive land use (rice mono-cultural with three crop/year or ...
