36. Carboxylic ester hydrolase in acute pancreatitis : a clinical and experimental study
Sammanfattning : Diagnosis of acute pancreatitis (AP) is erroneous in up to one third of patients when based on clinical criteria and elevated serum amylase values. Furthermore, according to autopsy reports fatal pancreatitis remains clinically undiagnosed in 22 to 86 % of hospitalised patients. LÄS MER
37. Biodegradable Surfactants Containing Hydrolyzable Bonds
Sammanfattning : Surfactants with built-in weak bonds, so-called cleavable surfactants, are interesting candidates in the search for more environmentally friendly alternatives to traditional surfactants. The objective of this thesis was to perform a systematic study in which cleavable surfactants with different hydrolyzable bonds were compared with regard to physicochemical properties, and chemical and biological stability.

38. Phytosterols. Effect of intake on cholesterol absorption and colorectal cancer risk
Sammanfattning : Phytosterols are lipid components of all food items of plant origin. They are effective in decreasing plasma cholesterol concentrations, but have also been suggested to protect against colorectal cancer. LÄS MER
39. Structure-Property Relationships of Surfactants at Interfaces and Polyelectrolyte-Surfactant Aggregates
Sammanfattning : The first part of this thesis is concerned with thestructure-property relationships in nonionic surfactantsystems. The main aim was to investigate how the surfactantstructure influences the adsorption at interfaces andinteractions between surfactant coated interfaces. LÄS MER
40. Radiation crosslinking of cellulose fibers to obtain rigid lightweight paperboard
Sammanfattning : Cellulosic materials are used in a wide range of areas of application, and one of these is paperboard for packaging solutions. Paper or paperboard as a packaging material has benefits like low density, low costs, high stiffness, good printability, and paper is environmentally friendly. LÄS MER
