Food packages preserve foodstuff during storage. Some packages have caps, some of which have internal pull rings for easy removal of a membrane that extend the shelf life. The pull-rings are injection molded directly onto the package in the filling machine at the customer site. Any defect in the pull ring causes filled packages to be discarded at a significant cost to the supply chain. Some batche

Fed aquaculture is a necessary practice to meet the seafood requirements of a growing population in a sustainable manner. There is a high demand for fish feed to meet the rising protein requirements of the industry. Currently, fish feeds are either unsustainable, affected by seasonal variations, lack a complete amino acid profile, lack scalability, or are too expensive. Single Cell Protein (SCP) i

The aggregation of amyloid β in the brain is considered to be the main cause of the currently incurable Alzheimer’s disease. Research investigating fibrils is being conducted continuously. Despite this, there is an incredibly large knowledge gap in what we know about the aggregation process. This study aims to investigate the temperature influence on the Aβ40 aggregation process using differential

Mikroplast har varit ett stort föroreningsproblem sedan början av plastens massproduktion på 1950-talet. Mikroplast bildas dels när plastmaterial avsiktligt skapas för att vara del av skönhetsprodukter och liknande och dels oavsiktligt, när plast bryts ner till mindre partiklar på grund av solljus, vind och regn. Detta kallas för primär respektive sekundär mikro-plast. Mikroplast är ett stort probMicroplastics (MPs) are a major pollution concern since the start of the mass produc-tion of plastics in the 1950s. MPs form A) when plastics are produced intentionally to be part of beauty products and B) when plastics are broken down into smaller particles by sunlight, wind, and rain. This is called primary and secondary microplastics, respectively. MPs are a concern because they can carry toxic

I takt med att antalet geoparker och tillgängliga geologiska besöksmål ökar föds ett behov av att förstå hur dessa kan användas för att öka den geologiska kunskapen i samhället. Ett av syftena med geoparker är att främja utbildning om hållbar utveckling och bevarande av både geologiska arv och Jorden. De senaste åren har tre svenska geoparker certifierats nationellt eller internationellt och ytter

In traffic assignment, one of the key elements is the validation process. The validation allows the traffic planner to get an understanding of whether the model is working according to reality-based metrics, or if it must be improved. There are several different ways of collecting reality-based metrics, one these methods are called GPS probe data. Through this study, a survey as well as a case stu

15% of all five year olds and 5-10% of all 7 year olds struggle with bedwetting, a condition medically known as enuresis. Current treatment methods rely primarily on the family to carry out an 8 week treatment. In order to involve healthcare providers in the process and create an opportunity for individualized treatments, Pjama AB has developed an enuresis alarm system. This system directly shares

This study aims to deepen the understanding of mundane consumption by examining hidden meanings in the case of the Milk Uprising, when sharp decreases in the availability of Skånemejerier’s milk in Scania, Sweden, in 2009 ignited a major consumer revolt. We argue that existing literature is inadequate to explain this case where mundane consumption all of a sudden became spectacular, and that such

In an effort to combat illegal cartel activities taking place in the European Union, in 1996 the European Commission decided to implement a leniency program for self-reporting firms who, in return for information about their cartel, could receive a substantial reduction, or a total exemption from any fines that would have otherwise been imposed on them. The wellbeing and survival of cartels is dep

Denna rapport är en brandteknisk riskvärdering av “Cube” i Lund, Sverige. Scenarioanalysen visade att tre utav de tio scenarier som undersöktes uppskattades vara av högre risk för personsäkerheten än övriga. Det var A - brand i receptionen på entréplan, B - brand på kontoret beläget på plan tre samt C - brand i restaurangen på entréplan. Scenarierna valdes därför ut för vidare analys och simuleriThis report is an evaluation of the fire safety of “Cube” in Lund, Sweden. The analysis of the different scenarios showed that three out of the ten scenarios chosen were deemed to be of a higher risk for human life than the remaining seven. The three scenarios were A - fire in the reception located on the ground floor, B - fire in the office space located of the third floor and C - fire in the re

The Brazilian economy is now financialized, where the finance sector and its priorities have become increasingly dominant in all aspects of the economy. At the same time, the country has been facing extremely high levels of inequality and is currently the 8th most unequal country in the world. This thesis aims to analyze the associations between the process of financialization and inequality trend

This Master Thesis is made in collaboration with ASSA ABLOY Entrance Systems and addresses the issues and problem areas of two dock leveler models; 60 kN and 100 kN to find a new improved design. After the following product development process, a new concept was created which could withstand applied forces exceedingly. The main purpose and goal of the project was to find a dock leveler design whi

Today, Swedish women have one of the highest participation rates. In the nineteenth century, however, virtually no married women were recorded as working. Their participation rates started rising around the turn-of-the-century. Using full-count microdata from Swedish national censuses for the period 1880-1910, this paper aims to estimate the effects of various determinants on female labour supply.

The presence of Nano particles in food is a topic that have gain much attention lately. The aim of this study is to investigate the aggregation behavior of nano silica under in vitro gastrointestinal conditions using asymmetric flow field flow fractionation (AF4) coupled with several detectors. Major part of this work is to find a suitable condition for the experiments. With measurements of Z-pote
