Synaptic dopamine release from embryonic nigral transplants has been monitored in the striatum of a patient with Parkinson's disease using [11C]-raclopride positron emission tomography to measure dopamine D2 receptor occupancy by the endogenous transmitter. In this patient, who had received a transplant in the right putamen 10 years earlier, grafts had restored both basal and drug-induced dopamine
Two hundred apparently healthy sexually active women, 17-34 years of age, who had presented for a general health check-up at the Clinic of Dermatology and Venereology, Medical University, Plovdiv, Bulgaria, were asked about genital symptoms, sexual behaviour, contraceptive use and smoking habits, and examined for signs of genital infections. They were searched for genital chlamydial infection, gon

The thesis has two aims. The first one is to contribute to the field of political and historical sociology through an understanding of the processes of state formation in a Third World country. The second aim is to describe and analyze the development of the Nicaraguan state from independence to 1990. In the first part of the dissertation theories of the nation-state and state formation are discus
RATIONALE AND OBJECTIVES: Patients with a posterior indentation in the pharyngoesophageal segment (PES) are generally considered to have an abnormality of the cricopharyngeal muscle (CPM). In this study we determined the actual width of the PES and the pressure circumstances during swallowing within the pharynx and PES in such patients. METHODS: Simultaneous videofluoroscopy and solid state manome
We report on a novel nonlinear laser spectroscopic technique for single-shot imaging of ground-state hydrogen atoms in harsh environments. H atoms from the ground state were first pumped to the 2s state via a two-photon excitation with a 243 nm laser beam, and the population of the 2s state was further probed through the 2s-4p transition with conventional polarization spectroscopy at 486 nm. A sin
Temporary agency work is one of the newest forms of work worldwide and growing rapidly over the past two decades. It is regarded as a tool to create jobs with a stepping-stone function to the labour market and to contribute to the demand of labour flexibility. However, with a triangular and flexible nature, temporary agency work as an irregular employment to some extent undermines the employment s
This thesis has two values. On one side, it aims at being a contribution to a betterunderstanding of the original concept of distributed economies. On the other side, it aspires atproviding useful decision criteria to those stakeholders that plan to locally develop a biogassystem.This thesis is developed from the Distributed Economies concept, which envisionsdecentralized, self-reliant and synergi
This study is about diplomatic recognition, and why some states have not received full diplomatic recognition from the international community. The central research-problem focuses on the factors that affect a state's foreign policy decision not to recognize other states. Taiwan and Kosovo are chosen as research-cases through a strategic case-selection. The theoretical framework used in this s
A flame-spread model is incorporated into a zone model, the WPI/Fire Code. The external heat flux’s influence on the model is discussed and a tolerable value is calculated. The input parameters to the flame-spread algorithm are exposed to a simple sensitivity analysis. The algorithm is compared with two scenarios, Model A and Model B. Model A compares experimental data from a free burning test whi
Syfte: Syftet med denna uppsats är att utvärdera implementeringen av Ready to Sell paketlösningar som del av IKEAs Lean Retailing strategi och jämföra denna med tidigare forskning inom Lean implementering och strategi implementering. Metod: Studien använder sig av en kvalitativ metod där intervjuer har genomförts. Denna metod har komplimenterats av en kvantitativ del som utgjorts av en enkät som i
This study aims at identifying and analysing the construct of a retailer’s store personality in consumer stories and how these stories relate to the retailer’s brand story on a global level. To fulfil the purpose and analyse a retailer’s store personality, a qualitative approach was chosen to analyse the empirical data provided by a case study of H&M through narrative analysis. The main theori
The dissertation is the result of an exchange year spent at the Department of archaeology at Glasgow University, Glasgow, Scotland. The direction was buildings archaeology and the course was called an M.phil. by research, a postgraduate degree. At the time, in 1996-97, it was somewhat equal to a Swedish magister degree. The object was St Mary´s priory and parish church of Monymusk, situated in Ab
The original task for our final thesis was to solve issues that are connected with exercise on the International Space Station, ISS. Those issues are mainly centered on the conflict between scientific and human needs perfect micro gravity conditions versus the needs to physically challenge the human body. Also psychological matters were central to the project exercise for the sake of science versu
Parallel kinematik machines are nowadays an important branch of investigation in the robotics field. Its design allows for high speeds, accelerations and tool forces as well as makes them ideals for faster cycle times and high repeatability works. TAU is a parallel kinematic machine from ABB Company with three degrees of freedom. Therefore, it can be positioned anywhere of the workspace but not or
