The investigation of periodic motions of constrained multibody systems requires the numerical solution of differential-algebraic boundary value problems. After briefly surveying the basics of periodic motion analysis the paper presents an extension of projected collocation methods [6] to a special class of boundary Value problems for multibody system equations with position and velocity constraint
BACKGROUND: In Crohn's disease high tissue expression and serum levels of chemokines and their receptors are known to correlate with disease activity. Because statins can reduce chemokine expression in patients with coronary diseases, we wanted to test whether this can be achieved in patients with Crohn's disease. METHODOLOGY/PRINCIPAL FINDINGS: We investigated plasma levels of chemokines (CCL2, C
Abstract in Italian Come gli altri dialetti della penisola salentina, il dialetto di Gallipoli è caratterizzato da un uso limitato dell’infinito. In alternativa alle costruzioni infinitive dell’italiano standard, il Gallipolino ricorre a costruzioni di forma finita rette da due complementatori: ka e ku. Tradizionalmente, il sistema di complementazione dei dialetti italiani meridionali è stato illuLike the other dialects spoken in the Salentine peninsula, the dialect from Gallipoli, Gallipolino, presents a limited use of infinitival clauses. Instead of several infinitival constructions as in standard Italian, we find some finite constructions introduced by two different complementizers: ka and ku. Traditionally, the phenomenon of the double complementation system in Southern Italian dialect
This article presents and analyses a new public Muslim voice that emerged in the political aftermath of the terrorist attacks in London in July 2005, in which the government reviewed its relations with Muslim communities. The Sufi Muslim Council (SMC) immediately attracted attention and criticism when it was launched in 2006, but it has not been studied in detail before. This article addresses the
The 39-item Parkinson's disease questionnaire (PDQ-39) is the most widely used patient-reported rating scale in Parkinson's disease (PD). However, recent studies have questioned its validity and it is unclear what scores represent. This study explored the possibility of regrouping PDQ-39 items into scales representing the International Classification of Functioning, Disability, and Health (ICF) co

AIMS: In western countries out-of-hospital ischaemic heart disease (IHD) deaths account for approximately 50-70% of all IHD deaths. The objective was to examine the trends in out-of-hospital IHD deaths in the Region of Skåne in southern Sweden, in different sex- and age-groups. METHODS: All 14,347 persons (range 24-110 years) in Skåne who died out-of-hospital between 1992 and 2003 from IHD (I410-
We demonstrate a method for nonintrusive scanned near-field optical microscopy. The microscope utilizes an optical trap to position accurately a 50-100-nm-diameter lithium niobate particle. The infrared trapping beam is frequency doubled in the particle, resulting in a visible microscopic optical probe. By separation of the trapping and detection wavelengths, objects that are transparent in the in
This paper presents results from one of the few existing outdoor measurement campaigns for UWB. We specifically focus on scenarios applicable for "infostations," where large amounts of data can be downloaded to a user within a limited amount of time. We describe the measurement setup, and present a novel high-resolution algorithm that allows the extraction of the scatterer's positions. Measuremen
BACKGROUND: Anandamide, a proposed endogenous cannabinoid (CB) agonist, has been shown to enhance neurogenic responses in vitro of the rat corpus cavernosal tissue (CC). However, no information is available on the distribution of CB-receptors or effects by anandamide in CC from primates or humans. OBJECTIVE: To characterize the distribution of CB-receptor isoforms in the human and primate CC and t
To evaluate an intervention aimed at enriching day centres for people with psychiatric disabilities by exploring staff experiences from developing and implementing the intervention.
A design for generating distributed input data for a regionalized version of the steady-state model PROFILE was tested by Monte Carlo simulations of critical loads of acidity for 67 sites within a south Swedish municipality, Svalov. Input and output data were integrated in a geographic information system for data manipulation and to facilitate its use in local planning. Pooled standard deviations
Currently, no ideal prostate cancer (PCa) diagnostic or prognostic test is available due to the lack of biomarkers with high sensitivity and specificity. There is an unmet medical need to develop combinations of multiple biomarkers which may have higher accuracy in detection of PCa and stratification of aggressive and indolent cancer patients. The aim of this study was to test two biomarker gene p
