- In Sweden, lime and lime-cement have been used for several decades as stabilising agents in deep stabilisation of soft soils. More recently, other types of binder have come into use, but so far only to a limited extent. In order to gather experience about the effect of various binders, laboratory tests have been performed on different types of soil stabilised with a range of binders. Lime, cement, fly ash and blast furnace slag in different combinations together with different admixtures, such as gypsum, silica fume and calcium chloride, have been used in the investigations. The variation in strength with type of binder has been studied, and comparisons have also been made with results from some previous investigations using different binders. The tests showed that there is no optimal, universal binder for stabilisation of the soils. Whereas some binders are robust, yielding good results in most types of soil, there are also binders that produce very good results in certain soils but poor results in others. Both similarities and differences in effects were found for different binders.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- PIXE-analyser kan utföras med utvecklad analysuppställning med noggrannhet och precision av c:a 10 % och med hög analyskapacitet. Ett dataprogram för evaluering av räntgenspektra presenteras. Inverkan av provtjocklek vid PIXE-analys av inhomogena prov har studerats och korrektioner föreslås. Fluorinnehållet i filterprov har bestämts, samtidigt med PIXE-analys, genom utnyttjande av en kärnfysikalisk reaktion som ger resultat med god noggrannhet och precision. Svetsaerosoler har karakteriserats m.h.a. PIXE, ESCA och TEM/EDAX. En uppställning för insamling av svetsaerosoler under utveckling och hittillsvarande resultat indikerar representativ provinsamling med god reproducerbarhet.

- Background: International organisations, e.g. WHO, stress the importance of competent registered nurses (RN) for the safety and quality of healthcare systems. Low competence among RNs has been shown to increase the morbidity and mortality of inpatients. Objectives: To investigate self-reported competence among nursing students on the point of graduation (NSPGs), using the Nurse Professional Competence (NPC) Scale, and to relate the findings to background factors. Methods and participants; The NPC Scale consists of 88 items within eight competence areas (CAs) and two overarching themes. Questions about socio-economic background and perceived overall quality of the degree programme were added. In total, 1086 NSPGs (mean age, 28.1[20-56] years, 87.3% women) from 11 universities/university colleges participated. Results: NSPGs reported significantly higher scores for Theme I "Patient-Related Nursing" than for Theme II "Organisation and Development of Nursing Care". Younger NSPGs (20-27 years) reported significantly higher scores for the CAs "Medical and Technical Care" and "Documentation and Information Technology". Female NSPGs scored significantly higher for "Value-Based Nursing". Those who had taken the nursing care programme at upper secondary school before the Bachelor of Science in Nursing (BSN) programme scored significantly higher on "Nursing Care", "Medical and Technical Care", "Teaching/Learning and Support", "Legislation in Nursing and Safety Planning" and on Theme I. Working extra paid hours in healthcare alongside the BSN programme contributed to significantly higher self-reported scores for four CAs and both themes. Clinical courses within the BSN programme contributed to perceived competence to a significantly higher degree than theoretical courses (932% vs 875% of NSPGs). Summary and conclusion: Mean scores reported by NSPGs were highest for the four CAs connected with patient-related nursing and lowest for CAs relating to organisation and development of nursing care. We conclude that the NPC Scale can be used to identify and measure aspects of self-reported competence among NSPGs. (C) 2015 Elsevier Ltd. All rights reserved.
