Background: The 39 item Parkinson's disease questionnaire (PDQ-39) is the most widely used patient reported rating scale in Parkinson's disease. However, several fundamental measurement assumptions necessary for confident use and interpretation of the eight PDQ-39 scales have not been fully addressed. Methods: Postal survey PDQ-39 data from 202 people with Parkinson's disease (54% men; mean age 70
The potential of algal–bacterial microcosms was studied for the biodegradation of salicylate, phenol and phenanthrene. The isolation and characterization of aerobic bacterial strains capable of mineralizing each pollutant were first conducted. Ralstonia basilensis was isolated for salicylate degradation, Acinetobacter haemolyticus for phenol and Pseudomonas migulae and Sphingomonas yanoikuyae for

A simple model is presented which interpolates between the DGLAP and BFKL regimes in deep inelastic cp scattering. This model is based on the CCFM and LDC models, and it is simple enough to provide an intuitive picture of the transition region between the two domains. Results are presented for both fixed and running coupling; for fixed coupling the transition between the domains occurs at a consta
A compact six-figure approximation formula for the inductance of a cylindrical current sheet is presented. The formula displays the correct asymptotic behavior in the respective cases of very long and very short coils. The efficiency of the approximation formula is due to a thorough analysis of the exact formula.
There is a need for mathematical modelling for the evaluation of important parameters for photon imaging systems. A Monte Carlo program which simulates medical imaging nuclear detectors has been developed. Different materials can be chosen for the detector, a cover and a phantom. Cylindrical, spherical, rectangular and more complex phantom and source shapes can be simulated. Photoelectric, incoher
Impaired appetite and weight changes are commonly seen in patients with depression, but the pathophysiology behind this imbalance between energy intake and energy expenditure remains largely unknown. The aim of this paper is to review the literature regarding a possible role for cytokines in the regulation of appetite and body weight, with special emphasis on depression. There now exists a substan
Purpose: Desmopressin is a well established and effective therapy for nocturnal enuresis. Water intoxication leading to hyponatremia is an infrequent but serious adverse event associated with desmopressin. We assessed the safety of desmopressin in children 18 years or younger with nocturnal enuresis with a focus on the relative safety of the oral compared with the intranasal formulation. Materials
This paper suggests sufficient conditions for asymptotically stable dynamical output feedback controller design based on the circle criterion. It is shown that a dynamic output feedback stabilization problem with impending problems of finite escape time, previously attacked by observer-based design, can be successfully solved using circle criterion design. Stability of the closed-loop system is gl
The 21+ isomer in 94Ag has recently been reported to have a two-proton decay branch to 92Rh. We have populated 92Rh through the 40Ca(58Ni,alphapn) reaction at 240 MeV, and have performed detailed spectroscopic measurements of the levels, finding new states and measuring angular distributions of gamma rays. We find no evidence for the states reported to be populated by the two-proton decay of 94Agm

Popular Abstract in Swedish Avhandlingen behandlar användandet av faltnings koder och Turbo koder för felkorrigering i radio system. Design av koder, avkodare samt metoder för återtransmission behandlas, i syfte att förbättra trafikkapaciteten i digitala radionätverk. Mer specifikt diskuteras design av låg-takts Turbo koder för spritt-spektrum fleranvändarsystem, list sekvens avkodning av länkade New wireless services such as mobile Internet, multimedia streaming and high speed packet data access are making their way to the market. Availability of low-cost equipment providing high transmission quality and efficient spectrum utilization is crucial to the success of these services. This thesis is a collection of papers that address an important step in this direction: efficient error control
We propose a method to improve the diagnosis of infection in the paranasal sinuses, distinguishing between mucous and serous cases. The method utilizes a previously published method whereby the viscosity in a sealed container may be measured using an ultrasound Doppler method. As ultrasound propagates in a liquid medium, due to attenuation, the resulting pressure gradient will cause the liquid to
The laminar burning velocity is a fundamental property of combustiblemixtures important for kinetic model validation as well as for practicalapplications. Many efforts are directed towards its accurate determination.The heat flux method is one of the commonly recognized methodsfor measuring laminar burning velocity, however, the information on theaccuracy of the method is scattered in the literatu
The collection of chapters in this book present the concept of matched filters: Response characteristics “matching” the characteristics of crucially important sensory inputs, which allows detection of vital sensory stimuli while sensory inputs not necessary for the survival of the animal tend to be filtered out, or sacrificed. The individual contributions discuss that the evolution of sensing syst
We argue that social robots should be designed to behave similarly to humans, and furthermore that social norms constitute the core of human interaction. Whether robots can be designed to behave in human-like ways turns on whether they can be designed to organize and coordinate their behavior with others’ social expectations. We suggest that social norms regulate interaction in real time, whereage
