1. In-plane Wetting in Packaging Material and its Consequences for Cap Performance
Master-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : Aseptic packaging solutions enable long time storage without refrigeration and are an important part of securing food supply globally. The package material consists of multiple layers: A paperboard for robustness, polymers for adhesion as well as shielding the board from liquid, and a barrier protecting the product. LÄS MER
2. Evaluation of antioxidant effect of an algae extract on skin: in vitro study
Kandidat-uppsats, Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)Sammanfattning : Algae extracts are used as cosmetic products and used as additives in specific foods because of their antioxidant activity. Reactive oxygen species (ROS) such as hydrogen peroxide and superoxide radicals are toxic on the skin and can be scavenged by antioxidants, which are abundant in microalgae. LÄS MER
3. Återvinning av platinametaller ur fordons katalysatorer : Litteraturstudie om återvinningsprocesser av katalysatorer inom fordonsindustrin med avseende på miljöpåverkan
Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Antalet bilar fortsätter att öka kraftigt i världen vilket skapar stora mängder av utsläpp som orsakar allvarliga miljöproblem. För att minska utsläppet av fordon med förbränningsmotorer används fordons katalysatorer. LÄS MER
4. Microplastics in food webs- occurrence in Lake Vänern brown trout (Salmo trutta) and its main prey
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Over the past decade, research on microplastic pollution has gained significant attention. Research regarding microplastic occurrence in freshwater fish, however is still scarce. While possible pathways have been investigated, passive transfer via ingestion of prey, and possible bioaccumulation in different organs remains relatively unstudied. LÄS MER
5. Metodutveckling för bestämning av kantinträngning av väteperoxid och mjölksyra i vätskekartong
Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)Sammanfattning : Hydrogen peroxide and Lactic acid Wick index are some of the most important parameters when the liquid board will be quality assured of the manufacture. The goal of this study is to improve and develop the existing analysis methods that Billerud AB uses to analyze the edge penetration of hydrogen peroxide and lactic acid in liquid boards. LÄS MER
