6. Psychological aspects in differences / disorders of sex development
Sammanfattning : Background: Sex differentiation depends on a complex set of molecular events. These are at one point initiated by SRY gene expression and involve gene transcription, which in turn can be affected by the prescence or absence of different co-factors, availability of and exposure to sex hormones, presence and sensitivity of steroid receptors that directs growth and development.

7. Mechanisms in disorders of sex development
Sammanfattning : “Is it a boy or a girl?” This is usually the first question that parents have when their baby is born. Sometimes it is not possible to give an immediate answer. This is the case when the newborn presents ambiguous external genitalia and an immediate sex assignment is not possible. LÄS MER
8. Towards sustainable plastics : Microbial production of aromatic and aliphatic building blocks from biobased feedstock and plastic hydrolysate
Sammanfattning : The current plastic system is unsustainable and needs to change. Plastics are mainly produced from fossil feedstock, contributing to greenhouse gas emissions, and low rate of post-consumer recycling results in pollution on land and in oceans with high ecological impact, and huge loss of valuable material.

9. Measuring Water Droplets to Detect Atmospheric Icing
Sammanfattning : This thesis describes the exploration of a method to measurethe droplet size and the concentration of atmospheric liquid water. The purpose is to find a cost effective technique to detect the conditions for icing on structures. LÄS MER
10. Hierarchical Modeling of Road Traffic Networks
Sammanfattning : The main objective of the thesis was to develop and applymethodologies for analysis and evaluation of the applicabilityof different types of road traffic simulation models for urbantraffic conditions. For this purpose a number of models ofmacroscopic, mesoscopic and microscopic type were applied,calibrated, validated and analyzed using extensive field datacollection to obtain traffic flow, travel time and queue-lengthdata for major road networks in Stockholm and Uppsala.
