1. Chloride transport and chloride threshold values : studies on concretes and mortars with Portland cement and limestone blended cement
Sammanfattning : Reinforced concrete is one of the most widely used building materials and if it is properly designed and produced, it is an extremely durable material with a service life up to 100 years. However, under certain environmental conditions the service life of reinforced concrete structures is more limited. LÄS MER
2. Collision Threshold Pressure : A novel measure of voice function Effects of vocal warm-up, vocal loading and resonance tube phonation in water
Sammanfattning : The phonation threshold pressure (PTP), i.e., the smallest amount of subglottal pressure needed to initiate and sustain vocal fold oscillation, is frequently difficult to measure due to the difficulty for some subjects to produce extremely soft phonation. In addition, PTP values are often quite scattered. LÄS MER
3. Tidens tröskel : Uppbrott och nostalgi i skandinavisk litteratur kring sekelskiftet 1900
Sammanfattning : This study illuminates Scandinavian literature’s engagement with the fin de siècle as a momentous temporal threshold, when the widespread feeling of being poised on the brink of a distinctly modern age while at the same time witnessing the demise of the old world produced excitement as well as anxiety, a sense of loss and nostalgia. The dissertation explores how three male authors of the Scandinavian canon – Ola Hansson, August Strindberg and Knut Hamsun – depict the ambivalent experience of being torn between nostalgia and a heady sense of departure.

4. Chloride Induced Corrosion of Reinforcement Steel in Concrete - Threshold Values and Ion Distributions at the Concrete-Steel Interface
Sammanfattning : The chloride threshold value (Cth), or critical chloride content, is defined as the chloride concentration at the depth of the reinforcement, which initiates the depassivation of steel in concrete. However, very limited information is available regarding the chloride distributions at the interface with the steel. LÄS MER
5. Improved computerized perimetric threshold strategies
Sammanfattning : Perimetric threshold examination is the most important method for diagnosing and monitoring patients with glaucoma. Such examination, however, is time-consuming and often difficult for the elderly patients in whom glaucoma is prevalent. Shorter test strategies have been proposed, but unfortunately also with lower test quality. LÄS MER
