1. Investigation of Milled Wood Lignin Extraction Using Enzymatic Hydrolysis for Application in Hydrophobic Barriers in the Food Packaging Industry
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : The objective of this report is twofold: to optimise the extraction method of lignin from spruce altering a few process parameters and to investigate the use of lignin as a hydrophobic barrier in food applications. The process used was STEX (steam explosion) pretreatment followed by enzymatic hydrolysis and MWL (milled wood lignin) extraction using a mixture of dioxane-water. LÄS MER
2. Novel materials from lignocellulosic sources- can they replace thermoplastics?
Kandidat-uppsats, KTH/Fiber- och polymerteknologiSammanfattning : Plastic waste is a severe environmental problem in today's society which has been noticed and discussed during the last couple of years. A constant increase of production over the last decades hasled to a large amount of plastic waste ending up in oceans as microplastics. LÄS MER
3. Composition and property study of adhesives based on poly(3-hydroxybutyrate-co-3-hydroxyvalerate)
Master-uppsats, KTH/Fiber- och polymerteknologiSammanfattning : Lim klassificeras som ett ämne som kan hålla ihop två ytor så att de motstår separation. Dagens lim kan anpassas efter vilken applikation de ska användas till och kan ha ett stort antal olika egenskaper. De fysikaliska och kemiska egenskaperna av limmet är de viktigaste faktorerna för att bilda en bra limbindning. LÄS MER
4. No effect of manganese coating or seed content : a study on germination and seedling establishment in Swedish winter wheat
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and EnvironmentSammanfattning : Manganese (Mn) is a micronutrient where a great range and low concentrations have been recorded in winter wheat seeds in a Swedish survey called the Swedish environmental monitoring program on arable soils. A deficiency of Mn is common in cereals and may occur early in the season if the plant availability of Mn is low in the soil. LÄS MER
5. Seroepidemiology of Peste des Petits Ruminants in central Tanzania alongside an evaluation of filter paper as transport medium
Master-uppsats, SLU/Dept. of Biomedical Sciences and Veterinary Public HealthSammanfattning : Peste des Petits Ruminants (PPR) is a disease of increased attention since the eradication of Rinderpest virus (RPV) in 2011. PPR is an acute and highly contagious viral disease of small ruminants caused by a Morbillivirus named Peste des petits ruminants virus (PPRV). LÄS MER
