Abstract in UndeterminedCombining sludge hydrolysis with predenitrification is a promising method to remove nitrogen and decreased use of external carbon content in wastewater. The Klagshamn wastewater treatment plant plans to alter the primary settler into an in-line hydrolysis basin with subsequent predenitrification to reduce the nitrate load into the overstrained moving-bed biofilm reactor. A
PURPOSE. To investigate in vivo morphology of corneal filaments. MATERIALS AND METHODS. Over a 12-year period, 19 patients with corneal filaments (7 with keratoconjunctivitis sicca and 12 with other surface diseases) were examined with the slit lamp and photographed by non-contact photomicrography. RESULTS. The filaments appeared as variously long and thick threads, attached at one or both ends to
Synaptic dopamine release from embryonic nigral transplants has been monitored in the striatum of a patient with Parkinson's disease using [11C]-raclopride positron emission tomography to measure dopamine D2 receptor occupancy by the endogenous transmitter. In this patient, who had received a transplant in the right putamen 10 years earlier, grafts had restored both basal and drug-induced dopamine
This paper studies the design of signaling waveforms for time-hopping impulse radio (TH-IR) with limits on the power spectral density. Such restrictions are imposed by the spectral mask prescribed by frequency regulators for ultra-wideband (UWB) signals. The "conventional" TH-IR system with pulse-position modulation and time-hopping multiple access gives rise to spectral lines that either violate
Popular Abstract in Swedish Vad säger notbilden? Notation är av central betydelse i västerländsk tonal musik. Repertoarens utsträckning över flera århundraden gör det angeläget att studera hur musikaliskt innehåll medieras genom notation. I denna studie har strategiskt utvalda musikers sätt att ta sig an noterna till tonal musik undersökts. Slutsatser har dragits beträffande notbildens funktionerAbstract Centering on notation is a characteristic of Western tonal music. The printed scores are expected to provide the necessary information on musical expression. In this study, strategically selected contemporary musicians’ ways of under-standing the printed scores are investigated. All participants are thoroughly familiar with musical practice in Western tonal tradition. The intention is to
BACKGROUND: Polyglutamine (polyQ) diseases are characterised by the expansion of CAG triplet repeats in specific genes. The accumulated encoded proteins affect the transcription of numerous transcription factors. We investigated whether polyQ diseases reduce the risk of cancer development. METHODS: Data on patients with the polyQ diseases Huntington's disease (HD), spinobulbar muscular atrophy (
We studied the impact of a family history of type 2 diabetes on physical fitness, lifestyle factors and diabetes-related metabolic factors. The Prevalence, Prediction and Prevention of Diabetes (PPP)-Botnia study is a population-based study in Western Finland, which includes a random sample of 5,208 individuals aged 18 to 75 years identified through the national Finnish Population Registry. Physic
By drawing from a number of studies in the field as well as the Snowden revelations and the case of MegaUpload/MEGA, the article makes an analysis of relevant legislation on privacy in the digital context. The purpose of the analysis is to understand to what extent and how the current paradigm of privacy protection is, or is not, sufficient for contemporary needs. In particular, we ask how privacy
Corrosion of steel structures in the marine environment is a major problem. The deterioration of this kind of structures is costly and difficult to predict both when designing new structures and when estimating the remaining service life time for existing structures. The aim of this investigation was to find indicative values for the corrosion rate of steel sheet piles on the Swedish west coast. S
In the present study, we have investigated whether changes in vascular reactivity in congestive heart failure (CHF) patients can be detected in the cutaneous microvessels and whether these changes are due to endothelial dysfunction, are affected by increasing age and related to an ongoing inflammation. The responses to local warming and iontophoretically administered endothelium-dependent and -ind
The Euro50 is an astronomical extremely large telescope for optical and infrared wavelength with a 50 m primary mirror. The telescope will have an elaborate control system ("live optics") to correct for atmospheric and telescope aberrations. To study and predict performance of the complete telescope system, an integrated model combining the structural model of the telescope, optics models, the con
It was recently proposed to use variational functionals based on manybody perturbation theory for the calculation of the total energies of many-electron systems. The accuracy of such functionals depends on the degree of sophistication of the underlying perturbation expansions. The energy functionals are variational in the sense that they can be evaluated at rather crude approximations to their ind
Students working in groups is a commonly used method of instruction in higher education, popularized by the introduction of problem based learning. As a result, management of small groups of people has become an important skill for teachers. The objective of our study is to investigate why conflicts arise in student groups at the Faculty of Engineering at Lund University and how teachers manage th
