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 ...

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 ...

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 unprecedented ...

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 ...

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 ...

In Asia, the rice root-knot nematode, Meloidogyne graminicola, is an important pathogen of Asian rice (Oryza sativa) in most rice producing countries including Myanmar. In the first part of our study, the damage potential of M. graminicola on commonly cultivated newly released high-yielding lowland rice varieties and upland rice varieties (traditional, improved and aerobic), which are being grown in different regions in the summer-irrigated ...

The rice root-knot nematode Meloidogyne graminicola is considered one of the most potentially important nematode pathogens of rice, especially in South and Southeast Asia, in a range of rice production systems. Identification of M. graminicola-resistant or -tolerant rice varieties will enable breeding programmes to develop rice varieties which are able to limit yield losses caused by this nematode species. The host response to M. graminicola ...

Two surveys were carried out during 2009. The first survey was during the dry summer season (mid-January to mid-May) in 450 rice fields from ten regions representing the summer-irrigated, lowland rice ecosystem in the lower Ayeyarwady delta area of Myanmar. The second survey was during the rainy (monsoon) season (mid-May to mid-October) in 102 rice fields from three regions representing the rainfed upland rice ecosystem in the northern hilly ...

Irrigated rice is less prone generally to phosphorus (P) deficiency than rainfed rice because redox reactions release P upon soil flooding. It is not known whether that is also true in highly weathered soils of Madagascar where the combination of high soil Fe and low P input may impede significant release of P. Soils and flag leaf samples were collected in 2010 in 38 irrigated rice and 46 rainfed rice fields belonging to private farmers. A ...
