Improved nutrient removal using in situ continuous on-line sensors with short response time

Nutrient sensors that can be located directly in the activated sludge processes are gaining in number at wastewater treatment plants. The in situ location of the sensors means that they can be located close to the processes that they aim to control and hence are perfectly suited for automatic process control. Compared to the location of automatic analysers in the effluent from the sedimentation re

Dietary habits after myocardial infarction - results from a cross-sectional study.

Objective. Comparing habitual nutrient intakes in persons with a history of acute myocardial infarction (AMI), and age-matched controls. Design. Cross-sectional study. Subjects. Men and women (525 cases and 1890 matched controls), aged 47-73 years, of the population-based Malmö Diet and Cancer cohort. Methods. Nutrient intakes were assessed by a validated modified diet history method. Body fatn

Effects of L-alanyl-L-glutamine dipeptide administration during 35 days of postnatal life on intestinal mucosa, bone properties, and performance of piglets in their early post-weaning period

The experiment was performed on piglets, divided into control and experimental groups The experimental group received orally, from the birth to the 35(th) d of life, 0.4 g/kg b.w./d of L-alanyl-L-glutamine dipeptide (Ala-Gln). One week after weaning the piglets were killed and the small intestine and bones were sampled for histological analyses. Measurements of bone physical and geometric properti

Stimulation of B and T cells activates expression of transcription and differentiation factors

During B and T cell differentiation and proliferation many genes are induced or repressed while certain genes are constitutively expressed. To investigate processes related to B and T cell activation, the gene expression of stimulated and nonstimutated Ramos and Jurkat cells was studied using cDNA microarray technology. Simultaneous analysis of close to 600 genes indicated highest increase in the

Theoretical study of water adsorption on the Ge(100) surface

We present first-principles density-functional calculations for the adsorption of water on the Ge(100) surface. The dissociation of water molecules into OH and H species is energetically favored over the molecular adsorption, where O forms a bond to the down atom of the Ge dimer, similar to the case of Si(100). However, on Ge(100) the energy barrier for water dissociation is calculated to be simil

Meniscal Tear - A Feature of Osteoarthritis

Popular Abstract in Swedish Artros (ledsvikt) är en vanligt förekommande ledsjukdom, som ofta leder till nedbrytning av ledbrosk och förändring i ledstrukturen i övrigt. Sjukdomen kan medföra symptom som smärta, svullnad och stelhet, vilket leder till nedsatt ledfunktion. I Sverige utförs det per år ca 15000 protesoperationer (utbyte till konstgjord led) p.g.a. artros. Tidigare studier har visat aMeniscectomy is recognized as an important risk factor for the development of knee osteoarthritis (OA), a disease that traditionally has been considered as a simple "wear and tear" phenomenon. However, despite numerous reports, little evidence has been presented that a limited meniscal resection, compared with a more extensive resection, reduces the risk of OA by preserving meniscal function. Why?

Derivation of the supersymmetric Harish-Chandra integral for UOSp(k(1)/2k(2))

The previous supersymmetric generalization of the unitary Harish-Chandra integral prompted the conjecture that the Harish-Chandra formula should have an extension to superspaces. We prove this conjecture for the unitary orthosymplectic supermanifold UOSp(k(1)/2k(2)). To this end, we construct and solve an eigenvalue equation.

Zigenarfrågan : Intervention och romantik

Popular Abstract in Swedish Det finns två etablerade sätt att beskriva zigenarnas historia i Sverige. Historien talar antingen om hur illa myndigheterna burit sig åt mot zigenare, eller så berättar historien om zigenarnas självvalda isolering. Gemensamt för beskrivningarna är påståendet att zigenare alltid varit desamma och uppvisar ett likartat levnadssätt genom historien. I denna avhandling studThis thesis analyses Swedish gypsy policy between 1880 and 1970, as part of a larger sociopolitical project undertaken by the Swedish authorities to promote social order and stability. During this period, the treatment of marginalized groups was shaped by the same visions and objectives as for the population as a whole. Gypsies in Sweden have been subject to the same regulations for as other poor

Couples therapy: effectiveness of treatment and long-term follow-up

Most couples therapy theories are developed and tested in the USA. In this clinical study, we investigated such therapies in a Swedish context. Over 300 couples were enrolled in the study of whom just under half completed the end-of-treatment assessment and just over 40 per cent a two-year follow-up. At the start, the study group displayed severe problems in marital adjustment, dyadic interactions

Differentiation of Helicobacter pylori isolates based on lectin binding of cell extracts in an agglutination assay

Plant and animal lectins with various carbohydrate specificities were used to type 35 Irish clinical isolates of Helicobacter pylori and the type strain NCTC 11637 in a microtiter plate assay. Initially, a panel of eight lectins with the indicated primary specificities were used: Anguilla anguilla (AAA), Lotus tetragonolobus (Lotus A), and Ulex europaeus I (UEA I), specific for -L-fucose; Solanum

Bioelectrocatalytic properties of lignin peroxidase from Phanerochaete chrysosporium in reactions with phenols, catechols and lignin-model compounds

Bioelectrocatalytic reduction of H2O2 catalysed by lignin peroxidase from Phanerochaete chrysosporium (LiP) was studied with LiP-modified graphite electrodes to elucidate the ability of UP to electro-enzymatically oxidise phenols, catechols, as well as veratryl alcohol (VA) and some other high-redox-potential lignin model compounds (LMC). Flow-through amperometric experiments performed at +0.1 V v

Modeling and Performance of Gas Turbine Cycles with Various Means of Blade Cooling

A method for simulating the cooled gas turbine is demonstrated. Based on equations and other knowledge found in the literature, a first-law thermodynamic, non-dimensional model is established and implemented in the equation-solving, programmable software IPSEpro. Increasing the water vapor or carbon dioxide contents of the gas turbine hot gas is found not to have an impact on the Stanton number,

Remotely sensed assessment of water quality levels in the Pearl River Estuary, China

In this paper, a method of assessing water quality from satellite data is introduced. The composite pollution index (CPI) was calculated from measured chemical oxygen demand (COD) and nutrient concentration. The relationships between CPI and 240 band combinations of SeaWiFS water-leaving radiance were analyzed and the optimal band combination for estimating CPI was chosen from the 240 band combina

Local host response in the lower respiratory tract in nephropathia epidemica

Various lines of evidence suggest a respiratory route of transmission of nephropathia epidemica (NE). To study the response of the respiratory tract in NE, fiberoptic bronchoscopy with bronchoalveolar lavage (BAL) was performed in 5 patients in the acute phase of the disease. Compared to a reference group of 15 healthy individuals, BAL fluid of NE patients contained significantly higher total numb

The Iron Age ritual building at Uppakra, southern Sweden

Six years ago we reported the discovery of a central place at Uppakra in southern Sweden which promised to be unusually rich and informative (Hardh 2000). At 40ha it already stood out as the largest concentration of residual phosphate in the whole province of Scania, with surface finds of Roman and late Iron Age metalwork (second-tenth century AD). Following this thorough evaluation, the project m

Polymorphism and recombination events at the ABO locus: a major challenge for genomic ABO blood grouping strategies

The blood group ABO gene codes for a glycosyltransferase that adds the ultimate monosaccharide to a glycoconjugate and forms the A or B blood group specific antigen. The DNA structure of the three major alleles of the human blood group ABO system was first described in 1990. This review describes the subsequent developments, including the increasing number of variants of these common alleles and t

Experimental Mg I oscillator strengths and radiative lifetimes for astrophysical applications on metal-poor stars - New data for the MgI b triplet

Context. The stellar abundance ratio of Mg/Fe is an important tool in diagnostics of galaxy evolution. In order to make reliable measurements of the Mg abundance of stars, it is necessary to have accurate values for the oscillator strength (f- value) of each of the observable transitions. In metal-poor stars the MgI 3p-4s triplet around 5175 angstrom (Fraunhofer's so-called b lines) are the most p
