This paper presents JitterTime, a small Matlab toolbox for calculating the transient performance of a control system in non-ideal timing scenarios.Such scenarios arise in networked and embedded systems, where several applications share a set of limited and varying resources.Technically, the toolbox evaluates the time-varying state covariance of a mixed continuous/discrete linear system driven by w
In this paper, a multi-scale model is used to assess the multiple mineral precipitation potential in a full-scale anaerobic granular sludge system. Reactor behaviour is analysed under different operational conditions (addition/no addition of reject water from dewatering of lime-stabilized biomass) and periods of time (short/long term). Model predictions suggest that a higher contribution of reject
An unbroken digital data flow would save substantial resources in the built environment process. In this study, which is part of a larger Swedish project, data delivery specifications and methods to integrate BIM and geodata are developed and tested with the aim to facilitate such an unbroken data flow. The main focus areas of the study are: (1) specifications that enables building permission appl
The investigations of light kaonic atoms offer the unique opportunity to perform experiments equivalent to scattering at vanishing relative energies, being their atomic binding energies in the keV range. This allows the determination of the hadron-nucleus interaction at threshold without the need of an extrapolation to zero relative energy. The energy shift and broadening of the lowest-lying state
Inflammation is a key feature of Parkinson’s disease (PD). In postmortem PD brains, microglial activation and enhanced major histocompatibility class II (MHCII) expression are seen concomitant to the accumulation of alpha-synuclein (α-synuclein) and loss of dopaminergic cells in the substantia nigra. Recent findings showed that α-synuclein epitopes can be presented and recognized by T-cells. PD is
Background: The exact pathophysiological mechanism(s) underlying endolymphatic hydrops (EH) remain elusive. We have previously shown that chronic administration of vasopressin and inhibitors of the cAMP/cGMP degrading enzymes (PDE3, PDE4, PDE5) results in the development of EH to mice. Aims/objectives: Evaluate the ability of spironolactone, an aldosterone antagonist, to prevent EH, when induced b
My PhD studies are tied to the research project The evolutionary periphery and will investigate the planning and pre-construction phase of the research facility ESS in Lund. Here the planning relates to future implications on the science community on a world scale, but also to the scale of immediate vicinity in form of local neighborhoods. As temporality and time dependent potential in urban plann
Parkinson’s disease (PD) is a heterogenous disease with a varying age of onset, symptoms, and rate of progression. This heterogeneity requires the use of a variety of animal models to study different aspects of the disease. Neurotoxin-based approaches include exposure of rodents or non-human primates to 6-OHDA, MPTP, and agrochemicals such as the pesticide rotenone, the herbicide paraquat, and the
ST segment depression (STDE) has been found to be associated with cardiovascular disease in the elderly. Studies of the relation of ambulatory STDE to cognitive function in elderly persons aged 80 years or above is lacking. Objective: To study the association between STDE and cognition. Design and participants: A cross-sectional cohort study of 88 81-year-old men from the population study "Men bor
Objectives: Health promotion is on the global agenda. The risks targeted include smoking, hazardous alcohol consumption, nutrition and insufficient physical activity. Implementation of clinical health promotion, however, remains a major challenge. While several processes, models and frameworks for strategic implementation exist, very few have been tested in randomized designs. Testing a strategic
BACKGROUND: Men born in 1914 is a population-based cohort study of the epidemiology of cardiovascular and cerebral disease. Little is known about how diurnal variation in blood pressure (BP) levels influence cerebral perfusion in very elderly populations. OBJECTIVES: To study the association between systolic (SBP) and diastolic BP (DBP) levels, during the day and at night, expressed through 24 h a
Eight family caregivers of elderly dementia sufferers participated in in-depth interviews regarding their experiences of giving care. They were selected according to strain, isolation, disappointment and emotional involvement, measured on a 'caregiver burden' scale. Structural analyses of the interviews identified six categories reflecting the feelings and experiences of the caregivers. The first
The strain of caregiving associated with the care of demented persons living at home often continues after relocation, and group-living-care units (GL), designed for a small number of subjects, have been developed. The aim was to prospectively describe caregiver burden in relationship to symptoms of patients with dementia after relocation to GL. Sixty-four caregivers and 64 demented patients were
The sensitivity of interglacial Greenland temperature to orbital and CO 2 forcing is investigated using the NorthGRIP ice core data and coupled ocean-atmosphere IPSL-CM4 model simulations. These simulations were conducted in response to different interglacial orbital configurations, and to increased CO 2 concentrations. These different forcings cause very distinct simulated seasonal and latitudina
Tumor promoting phorbol esters stimulate Ca++ phospholipid-dependent protein kinase C. It has been suggested that this enzyme regulates the functional properties of different cell membrane receptors. In this study we investigated the effect of phorbol esters on α1-adrenoceptor binding and phosphatidylinositol metabolism in cultured smooth muscle cells derived from rabbit aorta. Treatment of these
Plant water storage is fundamental to the functioning of terrestrial ecosystems by participating in plant metabolism, nutrient and sugar transport, and maintenance of the integrity of the hydraulic system of the plant. However, a global view of the size and dynamics of the water pools stored in plant tissues is still lacking. Here, we report global patterns of seasonal variations in ecosystem-scal
This chapter examines the communicational dynamic between adaptive and flexible CSOs. It focuses on women’s issues and citizen protest movements on the one hand, and political parties on the other, against the background of the extended protests that took place in Romania in the first half of 2012. These protests led to two changes in the government coalition and a significant reshuffling of the R
DDT1 MF-2 cells, which are derived from hamster vas deferens smooth muscle, contain α1-adrenergic receptors (54,800 ± 2700 sites per cell) that are coupled to stimulation of inositol phospholipid metabolism. Incubation of these cells with tumor-promoting phorbol esters, which stimulate calcium- and phospholipid-dependent protein kinase, leads to a marked attenuation of the ability of α1-receptor a
