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
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
By use of a batch microcalorimeter of the thermopile type, heat production was measured in isolated populations of human peripheral blood cells exposed to defined immune complexes formed in vitro. It was found that most of the heat production recorded in whole blood after admixture of immune complexes occurs in the granulocytes. Under these conditions small but constantly higher activation values

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

Despite an overwhelming scientific consensus that climate change poses severe risks to human and natural systems, many young Canadian adults do not view it as a major issue. We analyzed secondary science curricula in each province for their coverage of climate change according to six core topics: physical climate mechanisms (“It’s climate”), observed increase in temperature (“It’s warming”), anthr
