The development of a cell therapy for the neurodegenerative disorder Parkinson's disease is a realistic ambition. It is pursued by researchers and companies alike, and spans different donor tissue types of embryonic, fetal and adult origins. In this review, we briefly outline the past and current status of research and clinical trials with cell transplantation in Parkinson's disease. We discuss st
A linear quadratic stochastic control problem is considered. The problem involves several different controllers acting as a team, but with access to different measurements. Under appropriate assumptions on communication delays between the controllers, a quadratic control objective can be optimized using finite-dimensional convex optimization. Versions of this problem has been discussed in economic
Objectives/Hypothesis: The upper respiratory tract is involved in many acute and chronic respiratory tract diseases that present with the symptom of mucus hypersecretion. Mucin genes that encode for the backbone of glycoproteins contribute to the viscoelastic property of airway mucus. We examined the cellular expression and distribution of two major respiratory mucus-forming glycoproteins, MUC5AC
Fuel ethanol can be produced from lignocellulosic materials to replace gasoline and diesel. A crucial step in the production process is the hydrolysis (saccharification) of the material, which can be achieved with dilute acid at high temperature. Unfortunately, sugar is degraded under these severe conditions, and the sugar yield is generally low. This thesis deals with countercurrent operation, wh
This study tests the hypothesis that Fourier-transform infrared spectroscopy (FTIRS) of lake sediments can be used to infer past changes in tree-line position and total organic carbon (TOC) content of lake water. A training set of 100 lakes from northern Sweden spanning a broad altitudinal and TOC gradient from 0.7 to 14.9 mg/l was used to assess whether vegetation zones and TOC can be modelled fr
Background: Several studies have shown a higher mortality rate in patients with osteoporosis-related fractures of the hip and vertebrae. Method: In 1999, we did a long-term follow-up case-control mortality study of 253 patients, mean age 72 years, who had sustained a fracture of the surgical neck of the humerus in 1987. Results: We found a higher mortality in fracture patients giving at end point
We use the inverse scattering transform to show that a solution of the Camassa-Holm equation is identically zero whenever it vanishes on two horizontal half-lines in the x-t space. In particular, a solution that has compact support at two different times vanishes everywhere, proving that the Carnassa-Holm equation has infinite propagation speed. (c) 2006 Elsevier Inc.

This paper describes the philosophy behind our lighting of the RoboCup«99 games in Stockholm 1999. It also gives relevant background in the theory of light, lighting and colour in order to motivate our design. It is our hope that it will be a valuable source of information for future RoboCup game organisers.
Second or higher order probabilities have commonly been viewed with scepticism by those working within the realm of probability and decision theory. The aim of the present note is to show how the notion of second order probabilities can add to our understanding of judgmental and decision processes and how the traditional framework of Bayesian decision theory can be extended in a fruitful way by ta
The karyotype 47,XX, + 8,t(12;22)(p13;q12) was found at diagnosis in two patients with acute nonlymphocytic leukemia (ANLL). The bone marrow morphology of both patients corresponded to the M4 subtype of the French-American-British (FAB) classification. The translocation t(12;22) has not previously been reported as the sole structural aberration in ANLL.
The recently commissioned Recoil Mass Spectrometer (RMS) at the Holifield Radioactive Ion Beam Facility (HRIBF) is described. Consisting of a momentum separator followed by an E-D-E Rochester-type mass spectrometer, the RMS is the centerpiece of the nuclear structure endstation at the HRIBF. Designed to transport ions with rigidities near K = 100, the RMS has acceptances of +/- 10% in energy and +
We integrate scan-chain partitioning and preemptive test access mechanism (TAM) scheduling for core-based systems under power constraint. We also outline a flexible power conscious test wrapper to increase the flexibility in the scheduling process by (1) allowing several different bandwidths at cores and (2) controlling the cores test power consumption, which makes it possible to increase the test
The chemistry Of HfI4 adsorbed on the Si(100)-(2x1) surface has been studied by core level photoelectron spectroscopy in ultra-high vacuum. Two stable surface intermediates are identified: HfI3 and HfI2, both of which remain upon heating to 690 K. The dissociation of HfI4 is accompanied by the formation of SiI. In addition, HfI4 is Observed up to 300 K. Complete desorption of iodine occurs in the
The overall aim of the work presented in this thesis was to evaluate the incidence, outcome and consequences within the 1st year of acute ACL injury of the knee. The KANON-study, a randomized controlled clinical trial comparing surgical and non-surgical treatment after acute ACL injury, was initiated and some results are included in this thesis. 642 subjects with acute knee injury were assessed in
This study deals with the transformation of institutions of higher technical education in Sweden. It situates those processes in the context of educational reforms during the second half of the 20th century. Lund Institute of Technology, Lunds tekniska högskola (LTH), is focused upon. It was founded in 1961 as a major addition to the expanding higher education system. As a newly established instit
