1. 16. Statistical Modelling of Cell Cycle Dynamics Analysis and Interpretation of BrdUrd DNA FCM-Derived Data

   Författare :Sara Larsson Lönn; Matematisk statistik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; G2 phase duration; DNA replication; flow cytometry; Natural science; Naturvetenskap; S phase duration; DNA distribution; branching processes; cell cycle kinetics;

   Sammanfattning : It it of great importance to increase the knowledge of various cell cycle kinetic parameters and the objective of this thesis is to use stochastic models to interpret Bromodeoxyuridine (BrdUrd) DNA Flow Cytometry (FCM) derived data in order to estimate such parameters. The cell cycle is the process of growth and division that is essential for an organism to increase in size. LÄS MER

3. 17. Fundamental models and testing of creep in copper

   Författare :Fangfei Sui; Pavel A. Korzhavyi; Rolf Sandström; Alan Cocks; KTH; []
   Nyckelord :Copper; Creep tests; Multiaxial stress state; Finite element method; Basic modelling; Tertiary creep; Precipitation hardening;

   Sammanfattning : Many sustainable technologies for energy production, for example, generation IV nuclear system, demand the use of materials operating at elevated temperatures for long duration of up to 60 years. Requirements that are even more stringent are found for creep exposed copper canisters for disposal of spent nuclear waste. LÄS MER

4. 18. Pharmacometric Models for Antibacterial Agents to Improve Dosing Strategies

   Författare :Elisabet I Nielsen; Lena E Friberg; Otto Cars; Mats O Karlsson; Marie Sandström; Alan Forrest; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacometrics; pharmacokinetics; pharmacodynamics; modeling; NONMEM; antibiotics; in vitro; time-kill curve; PK PD indices; gentamicin; aminoglycosides; newborn infants; premature infants; cystatin C; Biopharmacy; Biofarmaci; Pharmacokinetics and Drug Therapy; Farmakokinetik och läkemedelsterapi;

   Sammanfattning : Antibiotics are among the most commonly prescribed drugs. Although the majority of these drugs were developed several decades ago, optimal dosage (dose, dosing interval and treatment duration) have still not been well defined. LÄS MER

5. 19. Essays on Econometric Theory

   Författare :Peter Jochumzen; Nationalekonomiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; economic theory; econometrics; Economics; measure of fit; unemployment insurance; non proportionality; stochastic frontier production function; diffusion of technology; Duration analysis; economic systems; economic policy; Nationalekonomi; ekonometri; ekonomisk teori; ekonomiska system; ekonomisk politik;

   Sammanfattning : This dissertation contains a variety of contributions to econometric theory. Broadly speaking, econometrics may be categorized depending on what type of data is being analyzed, the two main categories being time series data and cross sectional data. A third category is panel data, combining cross sectional data observed over time. LÄS MER

7. 20. Essays on Event History Analysis and the Effects of Social Programs on Individuals and Firms

   Författare :Stefano Lombardi; Johan Vikström; Oskar Nordström Skans; Conny Wunsch; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Labor Economics; Unemployment Insurance; Job Search; Monitoring and Sanctions; Policy Evaluation; Dynamic Treatment Evaluation; Duration Analysis; Firm performance; Employer-employee Match; Monte Carlo simulation; Economics; Nationalekonomi;

   Sammanfattning : Essay I: This paper studies threat effects of unemployment insurance (UI) benefit sanctions on job exit rates. Using a difference-in-differences design, I exploit two reforms of the Swedish UI system that made monitoring and sanctions considerably stricter at different points in time for different jobseeker groups.
