Water hardness is caused by magnesium and calcium ions (Mg2+ and Ca2+), and can result in formation of deposits, destruction of soap and increase of copper corrosion in old plumbing pipes. To soften the originally hard groundwater supplying 20% of Malmö’s drinking water, Bulltofta water treatment plant imports burned lime from Germany. Approximately 66 mg/L calcium is removed in the treatment plan
16S-bacterial data have been examined to evaluate the microbial community in ocean sediment along the coast of Helsingborg. Routine measurements of Escherichia coli (E. coli) in waters near recreational beaches in Helsingborg have been above the safe limit during several summers, even during dry conditions (such was the case in summer 2018). Stormwater, which previously have been the suspected mai
Sveriges riksdag har beslutat att FN:s konvention om barns rättigheter (Barnkonventionen) ska bli lagstadgad år 2020. Syftet med denna studie var att undersöka hur socialsekreterare vid enheten Barn och Familj uppfattar och talar om sina egna och andra samhällsaktörers tolkning av vad som är barnets bästa, och om de anser att dessa tolkningar påverkar samarbetet med andra organisationer. Metoden sSweden's government has decided that the United Nations Convention of the Rights of the Child (UNCRC) will be made into law by the year 2020. The aim of this study was therefore to explore how child welfare social workers perceive and talk about what affects their own and other community actors interpretation of the best interest of the child, and if they believe those interpretations have an
This study aims to investigate the factors influencing podcast listeners' intentions to redeem promotional codes from advertisements in this medium, focusing on the Theory of Planned Behavior (TPB) extended with the concept of trust towards podcast hosts. This research is based on the Theory of Planned Behavior while integrating trust as an additional predictor of intention to behave in the co
Vi lever i en värld där produkter konsumeras i en allt snabbare takt och där det sällan tas ansvar för det skapade avfallet. Plast är på många sätt ett otroligt material men det sätter en stor belastning på miljön både genom produktion och som avfall. Alternativ till konventionell, helt fossilbaserad plast har funnits och utvecklats under en tid nu, till exempel genom återvinning av PET-flaskor. IWe live in a world where products are consumed at an ever increasing rate, and where responsibility for the waste created is seldom taken. Plastics are in many ways wondrous materials, but they put a big strain on the environment, both in production and as waste. Alternatives to the conventional, virgin fossil-based plastics have been available and emerging for some time now, for example seen in t
The purpose of this study was to examine office designs, in terms of private, shared, and open plan offices. This was done by comparing the participants reported indoor climate, communication climate, and work engagement experienced in respective office design. The study was conducted with the background of the trend to use an open plan design in office spaces. Cross-sectional data on 2322 partici
When concrete slab frame bridges are designed with modern linear 3D FE-models large tensile restraint forces will arise in the transversal direction of the bridge from the temperature and shrinkage loads. These restraint forces are much larger than those that are accounted for in the older 2D models. This leads to that the amount of transversal reinforcement, calculated in the 3D FE-calculations,
Road traffic accidents in Sweden are today registered in the national database called STRADA (Swedish Traffic Accident Data Acquisition). To every accident information is gathered, but an efficient way of compiling this information is lacking. In countries like Germany or Denmark accidents are classified by the type of manoeuvre that leads to the accident. With help from reference tables, every m
More often than not one would encounter a problem, know that the solution has to meet some requirements, but do not how to start or how to progress towards solving it. Motivation for a computer that can solve the problem automatically without explicitly programming it is apparent, i.e. a computer that \programs itself", is greatly desired. The method of genetic programming has demonstrated it
Denna studie hade som mål att i första hand undersöka hur spatialt delad uppmärksamhet (spatial split-attention) i multimedia påverkar kognitiv belastning, men även hur individuella skillnader i objekt-spatiala visualiseringstilar kan påverka detta samspel. För att testa detta inkluderade vi både objektiva mått (svarstid) och subjektiva mått (självrapporter) av ovidkommande kognitiv belastning (exThe present study investigated firstly how spatial split-attention conditions in multimedia affects cognitive load, and secondly how individual differences in objectspatial imagery styles may affect this interplay. To test this, we included both objective measures (response time) and subjective measures (self-reports) of extraneous cognitive load in four different multimedia learning trials with s
This thesis investigated why U.S. hospitals that had committed to implementing communication and resolution programs (CRPs) did not consistently apply their programs when patient harm events occurred. Several themes emerged from interviews with nine risk management, patient safety, and patient experience professionals: the importance of informal social networks; workload and competing priorities a
The concept of this research is that by applying the proposed method, the trajectory of drift into failure can be made visible. The method itself consists of two sequential steps. For research purposes a third step is added. The first step is constructing a phased narrative, consisting of all the changes that have taken place within a particular organisational process subject to research. What has
Various studies on clientelism usually start from a common puzzle: Why is campaign clientelism widely practised by politicians even when they have no means of ensuring reciprocity from the voters? Similarly, why is campaign clientelism widespread amongst voters despite its numerous negative consequences on societies, democracy, and development? These puzzles have motivated my research, where I att
Background Activity-Based Costing is a costing method arisen in 1980’s as a response to changed cost structures. As business had become less labour intensive, Kaplan and Johnson argued that the traditional management accounting methods, using direct labour as cost base, were out-dated. Instead, Activity-Based Costing is based on the costs for the activities that the products require. The methodolo
This study presents a scoping review of tools to assess psychosocial stress in humanitarian aid workers, with a particular focus on the third version of the Copenhagen Psychosocial Questionnaire (COPSOQ III), and an overview of interventions to address work-related stress in this population. The databases Lubsearch and PsycInfo were searched for journal publications reporting on the validity of th
Dynamic pricing is a pricing strategy where prices are no longer fixed or constant. Instead, they are continuously readjusted according to perceived demand and factors that influence the desirability of the product. It is in passenger transport where it has one of its biggest applications, in order to increase profits and maximize the use of limited capacity. While extensively studied for its econ
As systems become increasingly more complex, it is doubtful that conventional models of accident investigation can provide insight into accidents which occur in these complex systems. In safety science this problem has been recognized, and accident models using a systems approach have been developed to illuminate these complex systems. However, they have not been widely applied in the railway sect
