Evaluation of plant-wide WWTP control strategies including the effects of filamentous bulking sludge

The main objective of this paper is to evaluate the effect of filamentous bulking sludge on the predicted performance of simulated plant-wide WWTP control strategies. First, as a reference case, several control strategies are implemented, simulated and evaluated using the IWA Benchmark Simulation Model No. 2 (BSM2). In a second series of simulations the parameters of the secondary settler model in

Zackenberg in a circumpolar context

Throughout the Northern Hemisphere, changes in local and regional climate conditions are coupled to the recurring and persistent large-scale patterns of pressure and circulation anomalies spanning vast geographical areas, the so-called teleconnection patterns. Indeed, the atmospheric fluctuations described by the North Atlantic Oscillation (NAO) are closely associated with the last four decades of

Search for a heavy neutral particle decaying into an electron and a muon using 1 fb(-1) of ATLAS data

A search is presented for a high mass neutral particle that decays directly to the e(+/-) mu(-/+) final state. The data sample was recorded by the ATLAS detector in root s = 7 TeV pp collisions at the LHC from March to June 2011 and corresponds to an integrated luminosity of 1.07 fb(-1). The data are found to be consistent with the Standard Model background. The high e(+/-) mu(-/+) mass region is

Measurement of the t(t)over-bar production cross section in the tau plus jets channel using the ATLAS detector

A measurement of the top quark pair production cross section in the final state with a hadronically decaying tau lepton and jets is presented. The analysis is based on proton-proton collision data recorded by the ATLAS experiment at the LHC, with a centre-of-mass energy of 7 TeV. The data sample corresponds to an integrated luminosity of 1.67 fb(-1). The cross section is measured to be sigma(t (t)

Diffusion length measurements in axial and radial heterostructured nanowires using cathodoluminescence

We have measured the ambipolar diffusion lengths in nanowires with GaAs and AlGaAs core material using cathodoluminescence imaging. This was done by combining III-V semiconductor materials with different bandgaps in single nanowires. We show that it is possible to record intensity profiles of the emission from segments of lower bandgap material positioned along the nanowire length and in this way

t(6;9)(p22; q34)/DEK-NUP214-rearranged pediatric myeloid leukemia: an international study of 62 patients

Acute myeloid leukemia with t(6; 9)(p22; q34) is listed as a distinct entity in the 2008 World Health Organization classification, but little is known about the clinical implications of t(6; 9)-positive myeloid leukemia in children. This international multicenter study presents the clinical and genetic characteristics of 62 pediatric patients with t(6; 9)/DEKNUP214-rearranged myeloid leukemia; 54

Characterization of a two-color pump-probe setup at FLASH using a velocity map imaging spectrometer

We report on the implementation of a high-count-rate charged particle imaging detector for two-color pump-probe experiments at the free electron laser in Hamburg (FLASH). In doing so, we have developed a procedure for finding the spatial and temporal overlap between the extreme UV free electron laser (FEL) pulses and the IR pulses, which allows for complete alignment of the setup in situations whe

Associations between mass media exposure and birth preparedness among women in southwestern Uganda: a community-based survey.

Background : Exposure to mass media provides increased awareness and knowledge, as well as changes in attitudes, social norms and behaviors that may lead to positive public health outcomes. Birth preparedness (i.e. the preparations for childbirth made by pregnant women, their families, and communities) increases the use of skilled birth attendants (SBAs) and hence reduces maternal morbidity and mo

Early amplitude-integrated EEG correlates with cord TNF-alpha and brain injury in very preterm infants

Aim: To investigate if the early electroencephalogram (EEG) and amplitude-integrated EEG (aEEG) in very preterm infants is affected by perinatal inflammation and brain injury, and correlates with long-term outcome. Methods: Sixteen infants born at 24-28 gestational weeks (median 25.5) had continuous EEG/aEEG during the first 72 h of life. Minimum and maximum EEG interburst intervals (IBI), and aEE

A 60 GHz receiver front-end with PLL based phase controlled LO generation for phased-arrays

This paper presents a front-end architecture for fully integrated 60 GHz phased array receivers. It employs LO-path beamforming using a phase controlled phase-locked loop (PC-PLL). To demonstrate the architecture a circuit is implemented featuring a two stage low noise amplifier, two cascaded active mixers, and a PC-PLL. The receiver downconverts the 60 GHz signal in two steps, using LO signals fr

Infarct quantification using 3D inversion recovery and 2D phase sensitive inversion recovery; validation in patients and ex vivo.

Cardiovascular-MR (CMR) is the gold standard for quantifying myocardial infarction using late gadolinium enhancement (LGE) technique. Both 2D- and 3D-LGE-sequences are used in clinical practise and in clinical and experimental studies for infarct quantification. Therefore the aim of this study was to investigate if image acquisitions with 2D- and 3D-LGE show the same infarct size in patients and e

N-CAM Exhibits a Regulatory Function in Pathological Angiogenesis in Oxygen Induced Retinopathy

Background: Diabetic retinopathy and retinopathy of prematurity are diseases caused by pathological angiogenesis in the retina as a consequence of local hypoxia. The underlying mechanism for epiretinal neovascularization (tuft formation), which contributes to blindness, has yet to be identified. Neural cell adhesion molecule (N-CAM) is expressed by Muller cells and astrocytes, which are in close c

An assessment of disease flare in patients with systemic lupus erythematosus: a comparison of BILAG 2004 and the flare version of SELENA

Aims To compare the British Isles Lupus Assessment Group (BILAG) 2004, the Safety of Estrogens in Lupus Erythematosus National Assessment (SELENA) flare index (SFI) and physician's global assessment (PGA) in assessing flares of disease activity in patients with systemic lupus erythematosus (SLE). Methods Sixteen patients with active SLE were assessed by a panel of 16 rheumatologists. The order in

Psychological aspects of patients with psoriasis: Biological and clinical studies

Popular Abstract in Swedish Psoriasis är en av våra vanligaste folksjukdomar, som drabbar 2-3 % av den vuxna befolkningen. Man vet i dag att många patienter med psoriasis lider av psykisk ohälsa och sänkt livskvalitet. Sjukdomen i sig innebär ofta en stor psykologisk påfrestning för patienten, men stress och psykisk ohälsa också kan vara en viktig orsak till insjuknande och återfall av psoriasis. Psychological distress is well known to be associated with psoriasis, both as a disease consequence, and as a causative factor for onset and exacerbations. Psychoneuroimmunological mechanisms have been suggested to be involved in the pathogenesis of psoriasis and have often been shown to be related to psychological distress and pruritus in psoriasis. The general aim of this thesis was to investig

Efter doktorsexamen - en alumnstudie

Forskarutbildningen har ett dubbelt syfte, att utbilda framtidens universitetslärare och forskare samt att utgöra rekryteringsbas för andra delar av offentlig sektor och privat sektor. Resultaten av denna alumnundersökning visar att Lunds universitet väl svarar upp mot detta dubbla rekryteringssyfte. Av doktoranderna i undersökningen, riktad till examinerade år 2004, hade nästan nästan samtliga (9
