Wastewater treatment plant operators encounter complex operational problems related to the activated sludge process and usually respond to these by applying their own intuition and by taking advantage of what they have learnt from past experiences of similar problems. However, previous process experiences are not easy to integrate in numerical control, and new tools must be developed to enable re-
To obtain full sky coverage, astronomical adaptive optics systemsrequire Na Sodium Beacons (SBs) (also referred to as Laser Guide Starsor LGSs) located at heights extending from 85 to 100 km. When viewed atthe edge of large telescopes these SBs appear elongated. For the Euro5050 meter aperture telescopes this elongation amounts to 6 to 9arcseconds when the laser is launched from a point on the tel
Maturity-onset diabetes of the young (MODY) is a heterogeneous single gene disorder characterized by non–insulin-dependent diabetes, an early onset and autosomal dominant inheritance. Mutations in six genes have been shown to cause MODY. Approximately 15–20% of families fitting MODY criteria do not have mutations in any of the known genes. These families provide a rich resource for the identificat
An analytical procedure based on microwave-assisted extraction (MAE) and standard addition was applied for the determination of banned azo dyes in bovine, sheep, and goat leather. Standard addition at four different concentration levels was performed using azo dyes, dissolved either in methanol or water. All dyes were determined indirectly by measuring their corresponding harmful aromatic amines,
I denna avhandling behandlas mätning av ventilation, flöden, volymer, luftomsättning samt luftutbytestid och kolvströmningsgrad för olika flödesvägar och strömningssätt i småhus med spårgas. Teori och mät- och beräkningsmetoder utvecklas och tillämpas vid fältmätningar i småhus. Som mätobjekt används allergikeranpassade enplansvillor byggda av LB-hus i Talldalen som är frånluftsventilerade och zon
Åren 1999–2003 avled drygt 3 000 patienter under intensivvård södra sjukvårdsregionen. I endast 6 procent av fallen (174 patienter) hade man konstaterat total hjärninfarkt med medicinska möjligheter till organdonation. Samtycke till organdonation gavs i drygt hälften av fallen. En motsvarande registrering kan i kvalitetssäkringsprogrammet för intensivvården (PASIVA) bli en rikstäckande kvalitetssäA complete registration of all deceased patients at intensive care units in the Southern Health region of Sweden has shown that 3,114 patients died during the five years from 1999 to 2003. Only 174 cases (5.6 per cent) were classified as potential organ donors according to the definition of total brain infarction (brain death) without medical contra-indications against organ donation.

Type 1 diabetes is a common, multifactorial disease with strong familial clustering (genetic risk ratio [{lambda}S] ~ 15). Approximately 40% of the familial aggregation of type 1 diabetes can be attributed to allelic variation of HLA loci in the major histocompatibility complex on chromosome 6p21 (locus-specific {lambda}S ~ 3). Three other disease susceptibility loci have been clearly demonstrated
Background. This case-control study was performed to evaluate whether adding first-trimester maternal serum testing to nuchal translucency measurement would improve the antenatal detection of Down's syndrome and decrease the number of women offered fetal karyotyping. Methods. In the Swedish Nuchal Translucency Trial 39,572 pregnant women were randomized to a routine scan at 12-14 gestational weeks
Galectins are implicated in a large variety of biological functions, many of which depend on their carbohydrate-binding ability. Fifteen members of the family have been identified in vertebrates based on binding to galactose (Gal) that is mediated by one or two, evolutionarily conserved, carbohydrate-recognition domains (CRDs). Variations in glycan structures expressed on glycoconjugates at the ce
The ability of dogs to adaptively modulate secretion by the exocrine pancreas to match changes in the amounts and sources of macronutrients is poorly understood. We evaluated the use of re-entrant pancreatic catheters as a non-terminal, temporary approach for the chronic collection of exocrine pancreatic secretion using unrestrained dogs fed diets differing in composition. Re-entrant catheters wer
The distribution of 50 species in the south Swedish provinces of Skane (Scania). Halland, Blekinge, Oland and Smaland has been mapped. Many of the species are endemic to southern Scandinavia and some are local endemics within the investigated area. However, there are also several species with a wider North European distribution. Within the area, the number of species shows a regular decline from t
Popular AbstractLandsbygdens landskap förändras ständigt. Ekonomi, teknik och politik används ofta för att förklara det som sker, men ingen av dessa krafter verkar direkt i landskapet. I praktiken är det beslut som fattas lokalt av enskilda brukare och markägare som sätter spår. Landskapet är där sammanvävt med den sociala miljön, och markanvändningen en integrerad del av den enskildes liv. Hur seFarmers and Landscape. Owners and farmers relations to their land, and the prospects for sustainable land use. In a transition towards sustainability, rural land use is of certain interest, owing to the environmental impact of modern farming and forestry, and also to its potential role in a recycling society. The prospects for sustainable land use depend on the farmers. Their conception of sustai
Methods of analysing and interpreting two-dimensional velocity field data in order to understand the scales of turbulence of bubbly two-phase flow were developed. Reynolds decomposition and large eddy simulation (LES) decompositions (low-pass filtering), in conjunction with proper orthogonal decomposition (POD) energy spectra analysis, as well as adjusted convective decomposition (constant convect
The thesis uses, as a starting point for a discussion of emergency response management, the problem of gradual coordinated adaptation of management functions in relation to an event and its dynamics. Empirical observations and analyses carried out in the research project show that important problemsolving processes not included in, and sometimes diverging from, planning and preparations frequently
To increase the overall ethanol yield from softwood, the steam pretreatment stage can be carried out in two steps. The two-step pretreatment process was evaluated from a techno-economic standpoint and compared with the one-step pretreatment process. The production plants considered were designed to utilize spruce as raw material and have a capacity of 200 000 tons/year. The two-step process result
A feed control strategy, based on estimated sugar concentrations, was developed with the purpose of avoiding severe inhibition of the yeast Saccharomyces cerevisiae during fermentation of spruce hydrolyzate. The sum of the fermentable hexose sugars, glucose and mannose, was estimated from on-line measurements of carbon dioxide evolution rate and biomass concentration by use of a simple stoichiomet
1 The effectiveness of antimuscarinic agents in the treatment of the overactive bladder (OAB) syndrome is thought to arise through blockade of bladder muscarinic receptors located on detrusor smooth muscle cells, as well as on nondetrusor structures. 2 Muscarinic M-3 receptors are primarily responsible for detrusor contraction. Limited evidence exists to suggest that M-2 receptors may have a role
