Världen behöver ställa om till en cirkulär ekonomi och asfalt är en produkt som är 100 procent återvinningsbar. Hanteringen börjar redan när beläggningen skall fräsas eller rivas. Genom att optimera denna process, kan asfalten återvinnas mer effektivt. Syftet med denna studie är att studera vad som förekommer med returasfalten när den fräses och vilka styrparametrar som asfaltfräsen kan påverka fö

N,N-diphenyl carbazolium salt has attracted interest for applications in anionic exchange membranes (AEM) due to its structural features and the high chemical stability that the compound exhibit. AEM are polymeric membranes with positively charged functional groups. They can be employed as electrolytes in alkaline fuel cells. In this project, different types of N,N-diphenyl carbazolium compounds w

This report describes a part of the product development process for a mechanical adjustment of the head pressure in an extruder at Tetra Pak. The pressure is adjusted by a valve that increases or decreases the pressure by moving a valve stem. In the current solution the valve stem is moved by hand, which will no longer be effective when Tetra Pak streamlines the extruder. The project also includes

A mathematical model for through drying of paper at constant pressure drop was developed. The model is based on physical properties; hence, basis weight, pressure drop, drying air temperature, pore size distribution, initial gas fraction, and tortuosity are important input parameters to the model. The model was solved for different combinations of the variables basis weight, drying air temperature

Background: Parents of children with complex right ventricular outflow tract (RVOT) anomalies are con-fronted with their child’s need for heart surgery early in life and repeated reoperations later on. Preoperative assessment needs to be performed whenever an indication for reoperation is suspected. The aim was to illuminate the experiences of parents of children diagnosed with RVOT anomalies, in

Color is the most obvious and easily determined soil property that can provide crucial information about soil composition. The NIX™ Pro color sensor (Nix) presents a user-friendly alternative to the traditional Munsell manual method, with reduced sensitivity to environmental and human factors. Therefore, a new method was developed to use Nix in combination with machine learning to quickly and affo

I dagens samhälle står ungdomarna inför flera problem i deras liv. För att handskas med dessa väljer ungdomarna olika sätt. Vid vissa tillfällen kan detta leda till att ungdomarna begår oönskade handlingar ur samhällets synpunkt. Genom att söka sig till gäng och därigenom leta efter svar på de problem som de ställs inför leds många ungdomar in i ett asocialt leverne. För att förhindra våra ungdomaIn today's society young people are faced with several problems in their lives. Young people choose different ways to deal with these. At times this can lead to young people committing undesirable actions from the society's point of view. By seeking to gangs and thus looking for the answers to the problems they faced led many young people into an anti-social lifestyle. In order to prevent

Strategies and methods for the internal crisis management of public organisations The aim of this research project is to contribute new knowledge, strategies and methods for the work of public organisations with internal crisis communication in view of and during extraordinary events. The field of crisis communication has received very little attention within research on crisis management. This is
