Dysfunction of the gastrointestinal tract has now been recognized to affect all stages of Parkinson's disease (PD). The consequences lead to problems with absorption of oral medication, erratic treatment response, as well as silent aspiration, which is one of the key risk factors in developing pneumonia. The issue is further complicated by other gut abnormalities, such as small intestinal bacteria
An X-ray absorption fine-structure spectroscopy (XAFS) cell that is suitable for solution-phase studies of the light elements in the series from Na+ and Ca2+ is described. This cell has an ultra-short pathlength that can be remotely adjusted using a miniature stepper-motor drive and thereby readily provides transmission pathlengths in the range from submicrometer to several hundred micrometers. Th
Detta är en kort rapport inom projektet ”Mätsystem för förändringsarbete”, utfört vid Institutionen för teknisk ekonomi och logistik vid Lunds Tekniska Högskola. Rapporten skall ses som ett komplement till slutrapporten ”Mätning av förändringsarbete: Utveckling och implementering av ett mätsystem för att mäta förändringstemperatur”.Projektet syftade till att ta fram ett ramverk för förändringsarbe
Accurate measurement of bank risk is a matter of considerable importance for bank regulation and supervision. Current practices in most countries emphasize reliance on financial statement data for assessing banks’ risk. However, the possibility of increased reliance on market-based risk indicators has been a topic for academic and regulatory debate for a long time. Market monitoring of bank risk h

Current-mode control can be used to control switched DC-DC power converters. This paper compares two continuous-time models for current-mode control that are made to be accurate up to half the switching frequency. The two models are the ones presented by Ridley and Tan. The closed loop frequency responses predicted by these two models are compared with results obtained from simulations of a buck c
Popular Abstract in Swedish Smärta kan betraktas som en varningssignal för annalkande eller redan inträffad vävnadsskada och har därigenom en uppenbar skyddsfunktion. Förmågan att genom snabba förändringar av pågående motorik avvärja en skadlig stimulering återfinns både hos människa och hos mer enkelt uppbyggda organismer långt ned på den fylogenetiska stegen. Den snabba bortdragning av handen soThe adult organization and postnatal development of the nociceptive withdrawal reflexes (NWR) of single hindlimb muscles were examined in decerebrate spinal rats using electromyography. In adult rats, NWR were found to perform highly organized sensorimotor transformations, with single muscles receiving excitatory cutaneous input from specific receptive fields (RF) whose distribution of sensitivity
Flame flashback from the combustion chamber to the premixing section is a major operability issue when using high H-2 content fuels in lean premixed combustors. Depending on the flow-field in the combustor, flashback can be triggered by different mechanisms. In this work, three flashback mechanisms of H-2/CH4 mixtures were visualized in an atmospheric variable swirl burner using high speed OH chem
Many existing accounts of African elections assume that voters base their electoral decisions on cues and incentives that are anchored in highly stable ethnic cleavage structures. Yet several newer contributions to the study of African electoral politics have questioned the ethno-clientelistic voting thesis and highlighted other determinants of vote choice, such as class, ideology and performance
The purpose of this work is the investigation of some constitutive and configurational aspects of phenomenological model formulations for a class of materials with history-dependent gradient microstructure. The assumption that the behavior of a material point is affected by history-dependent processes in a finite neighbor of this point yields an extended continuum characterized by non-simple mater
