Sammanfattning : A balanced tear film is essential for a healthy ocular surface. Insufficient tear production may result in dry eye, a common disorder in the elderly population. Dry eye causes significant discomfort in the patients and may lead to visual impairment and ocular infections. LÄS MER
2. On the Phase Behaviour of Soft Matter: Understanding Complex Interactions via Quantitative Imaging
Sammanfattning : The effect of microscopic colloid interactions on the resultant macroscopic phase behaviour is a frequently studied topic in soft matter resarch, and lies at the heart of this thesis. Key structural and dynamic properties of colloidal model systems across liquid-solid transitions are tracked using optical imaging techniques. LÄS MER
Sammanfattning : This thesis was performed to find ways to lessen the complications to pediatric cataract surgery, which is an increasingly safe procedure, also in infants. However, there are some complications to the surgery, which threatens the visual development. The most common complication is aftercataract. LÄS MER
Sammanfattning : Indoor environment may influence the occurrence of symptoms such as eye, skin and upper airway irritation, headache and fatigue. The aim of the dissertation was to study relations between subjective indoor air quality, such symptoms, clinical signs from the nose and the eyes and the physical indoor environment, in particular the effect of dampness, type of building, and air humidification.

Sammanfattning : Elastomers are the most commonly used materials for various sealing applications owing to their low modulus of elasticity, large elongation-at-break, and high Poisson's ratio. Most seals operate in the presence of lubricants; therefore the sealing elastomeroil interaction plays an important role in determining the tribological performance of elastomers. LÄS MER
