We introduce a novel soft antenna selection approach for multiple antenna systems through a joint design of both RF (radio frequency) and baseband signal processing. When only a limited number of frequency converters are available, conventional antenna selection schemes show severe performance degradation in most fading channels. To alleviate those degradations, we propose to adopt a transformatio
Background It is only recently that comorbidity in ADHD has come to the forefront as one of the most important aspects of the disorder. It is agreed that, often, these problems are at least as important as ADHD in contributing to the longer term outcome in the individual child. Objective To provide the reader with basic information about clinics and treatment of comorbidity in ADHD. Method Revie
Kinetics of interstitial oxygen loss and oxygen-related thermal double donor (TDD) generation upon heat treatments of Ge:O crystals at 350 degrees C have been studied. The TDD concentration (N-TDD) was derived from Hall effect measurements in the temperature range 77-400 K. The bistability of the first TDD species was taken into account. The interstitial oxygen concentration ([O-i]) in the crystal
OBJECTIVES: Long-term, low-dose macrolide therapy is effective in the treatment of chronic rhinosinusitis. It is believed that macrolide antibiotics produce this benefit through an anti-inflammatory effect. In this study, the effect of clarithromycin treatment on the expression of transforming growth factor (TGF)-beta and the key pro-inflammatory nuclear transcription factor, NF-kappa B, was exami
The personalities and qualities of nursing personnel are considered to be of great importance for their interactions and nursing relationships with patients and may also influence work satisfaction. The aim of the study was to explore the extent to which different personal qualities and personality factors, with a possible effect on motivation, professional conduct and coping with stress and anxie
Popular AbstractI denna studie står de brottslingar som befolkar amerikanska polis- och deckarserier i fokus. Två huvudgrupper urskiljs: De som begår brott på grund av de omständigheter de befinner sig i och de där brottsligheten framställs som en inre egenskap. I de olika avsnitten skildras hur de senare fördöms och exkluderas från den samhälleliga gemenskapen medan de förra förlåts för sin brottIn this study, American police- and detective-series are analysed. I focus on the portrayal of the criminals, especially the moral aspect. The series can be regarded as moral tales. The morality is embedded in the characters that populate the different episodes. There are two major categories of criminals in the series; the essentialized criminals and the ones that commit crimes due to circumstanc
The concept of perceptual defensiveness is related to subliminal perception and preconscious processing. Meta-analyses of earlier experiments, 6 in the United States and Holland and 10 in Iceland, on the Defense Mechanism Test (DMT)-ESP relationship had shown significantly higher ESP scoring by less defensive participants. In the present experiment, conducted in Freiburg, Germany, 50 participants
Experiments were conducted under growth chamber conditions in order to investigate the importance of the background light quality for the effect of UVB (280–320 nm) radiation on plants. Three week-old sugar beet (Beta vulgaris L.) plants were irradiated for three weeks with enhanced levels of UVB radiation with the following background light conditions: white light (WL) (350–700 nm), WL+UVA (suppl
PURPOSE: The low molecular mass and short half-life of free (f) prostate specific antigen (PSA) implies elimination from blood by glomerular filtration. In addition, patients with terminal renal failure have increased fPSA in serum but there have been sparse data reported on the rates and pathways of elimination of PSA complexes and human kallikrein 2 (hK2). We studied glomerular filtration depend
Objectives: To critically evaluate the available evidence base concerned with the diagnosis of pelvic inflammatory disease ( PID) based on clinical presentation, and to investigate the relation between signs and symptoms and the presence of laparoscopically diagnosed PID using the largest available dataset. Methods: The evidence base was critically evaluated and data collected by Lund University b
Swedish legislation and international norms emphasize society's obligation to ensure general accessibility. The possibility of independent outdoor mobility, transportation, and travel are as important for individuals with reduced functional capacity as for other members of society, but today their mobility is limited. The aim of this article is to outline a novel field for research collaboration b
A single stage anaerobic digester employing a sisal fibre waste fixed bed was studied for biogas production from sisal pulp waste. The fibre was colonized by microorganisms involved in biogas production. The sisal pulp waste to be digested was fed from the top and was sprinkled intermittently with recirculating leachate from the material. Organic loading rates of 0.1-10 kg volatile solids (VS) m-3
I discuss some recent development of Monte Carlo event generators and point out some problems. Starting with the issue of combining matrix element generators and parton shower algorithms, I will continue with discussing the problems associated with describing small-x final states and discuss some recent model developments for describing multiple partonic scatterings and underlying events in hadron
Low-temperature spectra of fully active (oxygen-evolving) Photosystem II (PSII) cores prepared from spinach exhibit well developed structure. Spectra of isolated sub-fragments of PSII cores establish that the native reaction centre is better structured and red-shifted compared to the isolated reaction centre. Laser illumination of PSII cores leads to efficient and deep spectral hole-burning. Measu
Popular Abstract in Swedish Under de senaste decennierna har förhoppningar om en ökad andel manlig personal i förskolans verksamhet uttryckts från samhällets sida. Förhoppningarna har dock inte infriats och antalet yrkesverksamma manliga förskollärare var cirka två procent i slutet av 1990-talet. Denna könsmässigt underrepresenterade grupp, som i sin yrkesutövning befinner sig i en kraftigt könsmäThe aim of this study is to describe and analyse the situation of male teachers in the day-to-day work of pre-school, taking into account the fact that men are underrepresented in this profession. The methodic field is qualitative. Video recordings and interviews have been carried out with the fourteen male pre-school teachers who have participated in the project. Some of these men work together w
Popular Abstract in Swedish Vad får buddhister i dagens moderniserade Thailand att ge stora delar av sin inkomst till munkar? Och varför är det så viktigt att munkarna framstår som oegennyttiga och undviker fysisk kontakt med kvinnor? Frågorna behandlas utförligt i denna religionsantropologiska studie, baserad på en längre tids fältarbete i centrala, norra och nordöstra Thailand. Sociala och poliThis dissertation, based on 14 months of fieldwork carried out in central, northern and north-eastern Thailand, focuses on laypeople's demands on contemporary Thai Theravada sangha. In the aftermath of the economic breakdown in 1997, an intense discussion concerning the moral status of the sangha took place. The religious interests and demands clearly differ between different groups. What still se
