Kemiska angrepp av sulfater och svavelsyra är ett allt vanligare problem på svenska avloppsrör i betong. Inte minst tillverkarna av betongrör har märkt av ökningen, trots att deras rör uppfyller de krav som ställs är den faktiska beständigheten sämre än förväntat.

Bakgrund: Dagens logistik måste aktivt arbeta med att minska på mängden matsvinn som uppstår i försörjningskedjor. Denna studie visar hur livsmedelsindustrin kan använda sig av innovativa lösningar så som intelligenta förpackningar för att förbättra kvalitetssäkringen av logistiktjänsterna. Under tempererade transporter exponeras förpackningar för varierande temperatur, luftfuktighet samt vibratio
Vid kusten får man ofta vända kappan efter vinden på grund av det oberäkneliga vädret. Vind, temperatur och molnighet kan variera mycket på kort tid och på korta avstånd. Ett speciellt igenkännbart fenomen under molnfria sommardagar i havsnära områden är den svalkande vinden från havet, som friskar i under morgonen och mojnar mot kvällen. Vinden kallas sjöbris, eller havsbris, och den är orsakenSea breezes are widespread mesoscale phenomena that occur in coastal areas all over the world. This phenomenon affects the coastal weather and can give rise to strong convection and thunderstorms, and is therefore of importance for operational weather prediction, leisure activities and studies in pollution dispersion and wind power production. This study aims at analyzing a possible sea-breeze ca
Conditional cash transfer (CCT) programs have become an increasingly popular policy approach in the fight against poverty. In addition to their main goal of reducing poverty, CCT programs are also often claimed to have positive short-term impacts on beneficiary women. This is an interesting claim to examine further since gender equality and female empowerment are generally seen as key issues in gl
A condition for patient choice in health care to promote quality is that patients act in accordance with information about quality and change to better care providers.

Villa homes are designed to be able to tackle many injured leading factors. Today's villa homes are planned and projected by many years of experience in villa construction. No matter how well you planned the project planning and execute it, an injury can occur. Moisture and water damage can occur from a variety of factors, both from the outer- and inner factors. The external factors may be in
Steel structures in an offshore processing environment must be designed for an accidental explosion event. The current verification procedure implemented at Aker Solutions (AKSO) enforces an elastic single degree of freedom (SDOF) analogy to implicitly account for dynamic effects in linear static FE analyses. The implication of this approach is that structures are designed to remain within their e

To give daily or weekly care to a parent, step parent or parent in law is found to be more common among women than among men and is associated with lower employment probability for daily caregivers although the causal direction of the relationship is unclear. No negative effect of

The investigation is partly based on an article “Novel anticorrosion coatings prepared from polyaniline/graphene composites” from 2012 by Chang et al in combination of
