A hypothesis regarding the mechanism causing salt frost scaling on Portland cement-bound materials is described. It is assumed that deterioration is due to osmotic micro ice body growth, as has been previously proposed for frost deterioration of moisture-isolated specimens of cement-bound materials. In moisture-isolated specimens, this ice body growth stops when the micro structure is drained to a

Objective:The European Surgical Outcomes Study described mortality following in-patient surgery. Several factors were identified that were able to predict poor outcomes in a multivariate analysis. These included age, procedure urgency, severity and type and the American Association of Anaesthesia score. This study describes in greater detail the relationship between the American Association of Ana

One reason for cultvating Vibrio cholera is for production of CTB, which is a component in a cholera vaccine. Techniques of high cell density fermentation developed for recombinant E. coli are investigated.In the literature there is evidence of acetate formation when cultivating V. cholerae, and it is probable that the acetate has the same negative consequences for V. cholerae as for E. coli. Form

Analyses of testate amoebae and aeolian sediment influx (ASI) were used to reconstruct effective humidity changes and aeolian activity in the coastal zone of south-west Sweden. Cores were taken from an ombrotrophic peat sequence from the Undarsmosse bog. Since both types of analysis were carried out on the same core, a direct comparison between humidity fluctuations in the bog and aeolian activity

xtbcfe is a bootstrap-corrected fixed effects (LSDV) estimator for dynamic panel data models of general order. It estimates the specified model with the fixed effects estimator and corrects its small T bias (see Nickell, 1981) using a simplified but extended version of the approach presented in Everaert and Pozzi (2007). The algorithm evaluates the bias of the fixed effects estimator in a numerica

The thesis addresses a practical problem that has recently emerged on the Swedish public procurement law agenda; the fact that a considerable number of initiated tender procedures are cancelled by the contracting authority. During the last decade, the number of cancelled tenders has increased yearly and in 2017 over 13 percent of the initiated procedures governed by the EU public procurement regul

Genetic revelations in 2014 are testing traditional classification systems for movement disorders, and our approach to clinical diagnostics. Mutations in dystonia-associated genes lead to a spectrum of disorders with different phenotypes, underscoring the need for stringent clinical phenotyping of patients with movement disorders, as well as next-generation sequencing approaches.
