In this paper, a control strategy for introducing enhanced biological phosphorus removal (EBPR) in an alternating plant designed for enhanced biological nitrogen removal (EBNR) is presented. Alternating aerobic and anaerobic conditions to promote EBPR are provided by controlling the phases of the operational cycle, instead of a separate anaerobic volume. By utilising the control schemes already bu
We present a multiplexed and internally calibrated quantitative reverse transcription-PCR (QRT-PCR) assay to detect human glandular kallikrein 2 (hK2) and prostate-specific antigen (PSA) transcripts in blood samples from healthy subjects and prostate cancer (PC) patients. The assay detected 50 copies of hK2 and PSA mRNA, and 1 PSA- and 10 hK2-expressing LNCaP cells in the presence of 2.5 x 10(6) P
Helicobacter pylori causes gastritis, peptic ulcer disease and gastric cancer. The microbe is found in the gastric mucus layer where a pH gradient ranging from acidic in the lumen to neutral at the cell surface is maintained. The aim of the present study was to investigate the effects of pH on H. pylori binding to gastric mucins from healthy individuals. At pH 3, all strains bound to the most char
An important step towards understanding the function of olivo-cerebellar climbing fibres must be to clarify what they signal. We suggest that climbing fibres projecting to paravermal cerebellum mediate highly integrated sensorimotor information derived from activity in spinal withdrawal reflex modules acting on single forelimb muscles. To test this hypothesis, cutaneous nociceptive receptive field
Genomgång av illustrationer till Axel Wallengrens "fakiriska" verk och hur dessa förhåller sig dels till själva texterna och dels till dessas upphovsman.
Popular AbstractAvhandlingens titel Den goda viljans paradoxer skall förstås på följande sätt. I utredningar och propositioner hävdar utredare, skolpolitiker och administratörer att lärarna skall bemyndigas, det vill säga de skall tillskrivas ett mandat i skolan. Detta mandat skall ge lärarna ett visst självständigt beslutsfattande i en ny mötesform som kallas arbetsenheter. Denna mötesform stipulThe theory and practice of reform as reflected in teachers’ experience of meetings in schools. This empirical study has been carried out in a coeducational school for pupils up to the age of 16 ("grundskola") during the school years 1988-89 up to and including 1991/92. In this study 26 teachers and five school administrators - head teachers and deputy-head teachers - have been interviewed. Person
The molecular self-diffusion in concentrated aqueous mixtures based on an oppositely charged po ymer-surfactant pair has been investigated by NMR pulsed field gradient techniques. The investigated structures were an ordered cubic Pm3n phase (ca. 50 wt % water) and a disordered micellar phase, both containing cetyltrimethylammonium (CTA(+)) micelles with mixed acetate (Ac-) and polyacrylate (PA(-))
Investigation of travel-domain dialogues reveals travel-agent (apSystem) utterances with intonational contours characterized by late-timed focal accents on given information. These accents occur on content words in utterance-initial position. The accentuation can be assumed to be related to the interactive nature of the dialogue in which the travel agent links back to a domain-related concept intr
Using DTT and iodoacetamide as a novel irreversible method to inhibit endogenous violaxanthin de-epoxidase, we found that violaxanthin could be converted into zeaxanthin from both sides of the thylakoid membrane provided that purified violaxanthin de-epoxidase was added. The maximum conversion was the same from both sides of the membrane. Temperature was found to have a strong influence both on th
The breakdown of traditional marine tenure systems and overexploitation of marine organisms as a result of rapid modernization, urbanization and population growth in the case of Tonga is outlined. The customary marine tenure system is described and the threats against the coral reefs are discussed. It is shown how accumulative strategies correlate with the move toward overexploitation. It is argue
Aims: To explore the prevalence of overweight in men and women in a Swedish rural community and to examine its associations with all-cause mortality. Methods: A community-based cohort study. A total of 1,109 men and women aged ≥40 years participated in a survey of cardiovascular disease (CVD) risk factors in the city of Skara in Skaraborg, Sweden, in 1993—94. Overweight was defined as a BMI≥25.0 k
OBJECTIVE: To investigate the relationships between characteristics of the living situation in the community and subjective quality of life and social network among community-based individuals with schizophrenia. METHOD: A total of 418 individuals with schizophrenia from 10 sites were interviewed with regard to quality of life, psychopathology, social network and needs for care. Characteristics of
The photoinduced electron-transfer reactions in a Mn-2(II.II)-R-II-NDI triad (1) ([Mn-2(bpmp)(OAc)(2)](+), bpmp = 2,6-bis[bis(2-pyridylmethyl)aminomethyl]-4-methyiphenolate and OAc = acetate, R-II = trisbipyridine ruthenium(II), and NDI = naphthalenediimide) have been studied by time-resolved optical and EPR spectroscopy. Complex 1 is the first synthetically linked electron donor-sensitizer-accept
BACKGROUND: Osteoarthritis of the hands is a prevalent musculoskeletal disease with a considerable effect on patients' lives, but knowledge and research results in the field of hand osteoarthritis are limited. Therefore, the Disease Characteristics in Hand OA (DICHOA) initiative was founded in early 2005 with the aim of addressing key issues and facilitating research into hand osteoarthritis. OBJE
A measure of coherence is said to be truth conducive if and only if a higher degree of coherence (as measured) results in a higher likelihood of truth. Recent impossibility results strongly indicate that there are no (non-trivial) probabilistic coherence measures that are truth conducive. Indeed, this holds even if truth conduciveness is understood in a weak ceteris paribus sense (Bovens & Har
Consider a process of events on a line L, where, for the most part, the events occur randomly in both time and location. A scatterplot of the pair that represents position on the line, and occurrence time, will resemble a bivariate stochastic point process in a plane, P say. If, however, some of the points on L arise through a more regular phenomenon which travels along the line at an approximatel
Dissociation of 227 MeV/u 8He in a carbon target has been studied in kinematically complete experiments. The data include the relative energy spectrum, angular distributions in the neutron knock-out channel (6He+n) as well as diffractive dissociation and inelastic scattering into the (6He+2n) channel. The data are compared with corresponding results from the well-known halo nucleus 6He. In both ca
Objective: To evaluate effects of lipopolysaccharide (endotoxin) on protein and fluid permeability in a whole organ skeletal muscle preparation. Design: Controlled, prospective laboratory study. Setting: University research laboratory. Subjects: Eleven adult male cats. Interventions: The study was performed on the autoperfused and denervated calf muscles of the cat hindlimb placed in a fluid-fille
