The removal of chemical oxygen demand (COD) from wastewater-containing phenol was investigated using three-phase three-dimensional electrode reactor. Special attention was paid to experimentally probe the performance of the reactor in COD removal in the process of repeated batch runs. The experimental results showed that the reactor could remove COD from phenol-containing wastewater much more effi
The identification, prevention, and prompt treatment of exacerbations are major objectives of asthma management. We looked at change in PEF, symptoms, and use of rescue beta-agonists during the 425 severe exacerbations that occurred during a 12-mo parallel group study (FACET) in which low and high doses of budesonide with and without formoterol were compared in patients with asthma. Oral corticost
On 30 October 2003, an ongoing geomagnetic superstorm knocked down a part of the high- voltage power transmission system in southern Sweden. The blackout lasted for an hour and left about 50,000 customers without electricity. The incident was probably the most severe geomagnetically induced current ( GIC) failure observed since the well- known March 1989 Quebec blackout. The " three- phase'' storm
The aim of this study was to compare the performance of the enzymes produced by Trichoderma reesei Rut C30 and the good extracellular beta-glucosidase-producing mutant Trichoderma atroviride TUB F-1663 to that of commercial preparations in the enzymatic hydrolysis and the simultaneous saccharification and fermentation (SSF) of steam-pretreated spruce (SPS). The concentrated TUB F-1663 enzyme was f
The titanium dioxide (TiO2) nanotube surface enables significantly accelerated osteoblast adhesion and exhibits strong bonding with bone. We prepared various sizes (30-100 nm diameter) of titanium dioxide (TiO2) nanotubes on titanium substrates by anodization and investigated the osteoblast cellular behavior in response to these different nanotube sizes. The unique and striking result of this stud
Severe hypoglycemia was induced by insulin in lightly anaesthetized (70°o N2O) and artificially ventilated rats. Brain tissue was frozen in situ after spontaneous EEG potentials had disappeared for 5. 10. 15 or 30 min and cerebral cortex concentrations of labile organic phosphates, glycolytic metabolites, ammonia and amino acids were determined. In other experiments, recovery was induced by glucos
Helicobacter pylori exists in two different morphological forms, spiral and coccoid. This study demonstrated that both forms can infect BALB/c A mice. The animals were inoculated orally three times at 2-day intervals with 10(8) cfu of both spiral and coccoid forms of strain CCUG 17874 (NCTC 11637), strain 25 and strain 553/93. Infection was followed over a 30-week period by histological scoring of
While preterm contractions occur almost as often extremely preterm as they do closer to term, birth due to spontaneous preterm labour before 27 weeks of gestation is rare, accounting for 0.05–0.7% of all births in different populations. Although the likelihood that uterine contractions before 27 weeks of gestation represent true preterm labour is low, the risk of adverse outcome in such cases is h
This report is based on 1.851 adult patients with soft tissue sarcoma (STS) of the extremities or trunk wall diagnosed between 1986 and 1997 and reported from all tertiary referral centers in Norway and Sweden. The median age at diagnosis was 65 years and the male-to-female ratio was 1.1:1. One third of the tumors were subcutaneous, one third deep, intramuscular and one third deep, extramuscular.
The PIXE technique offers the possibility of scanning a single hair strand longitudinally with a millimetre proton beam for trace elements. However, the accuracy of the method has been questioned since the quantification of the mass concentration has been a serious problem. In this paper a specific beam-hair-detector geometry is assumed, and the correction factor accounting for the proton energy l
The present study collected and analyzed flow boiling data points which fall in the annular flow regime with an increasing heat transfer coefficient h - vapor quality x trend (h increases with increasing x) in small diameter channels (0.1 < dh < 3.1 mm) for halogenated refrigerants, CO2 and water. In this annular flow regime, heat transfer coefficient also depends on both heat flux and mass flux.
Popular Abstract in Swedish In conclusion we show that basement membrane components are present in cartilage ECM and that they may serve roles both as BM functional equivalents as well as organizational roles during ECM formation. Den extracellulära matrixen (ECM) är ett nätverk av makromolekyler som, tillsammans med celler, bildar de olika vävnaderna I alla organismer från phylum metazoa. Till sThe extracellular matrix (ECM) is a network of macromolecules which, together with cells, forms the various tissues of all metazoan organisms. Cartilage, in contrast to most other tissues, contains relatively few cells in proportion to the volume occupied by ECM. Part of this work involves investigation of cartilage ECM for expression and secretion of proteins that are considered to be the definin
Established tumour cell lines are ubiquitous tools in research, but their representativity is often debated. One possible caveat is that many cell lines are derived from cells with genomic instability, potentially leading to genotype changes in vitro. We applied SNP-array analysis to an established tumour cell line (WiT49). Even though WiT49 exhibited chromosome segregation errors in 30% of cell d
The Svalbard Seed Vault serves as a backup against accidental loss of genetic crop diversity within the existing global conservation system. Addressing this objective, this thesis repeats the 2013 assessment of the Seed Vault’s completeness relative to the global conservation system as performed by Westengen et al (2013, 1). It is shown that gaps have continued to exist in Svalbard’s collection. S
A recent body of empirical studies has given us a reason to expect that an influx of low-skilled workers can increase high skilled female market labour supply. Most of these studies, however, have focused on developed countries and on investigating the impact as it pertains to immigration. Believing that this same effect might hold in the case of internal migration, in this study, I employ a shift-s
När någon går bort försvinner inte det den avlidne efterlämnar sig automatiskt. Ett dödsbo bildas som omfattar den avlidnes tillgångar och skulder. Normalt sett kommer dödsboet att förvaltas av dödsbodelägarna, det vill säga de som på något sätt kommer ha del av det som ingår i dödsboet genom arv eller genom testamente. Det ska eventuellt göras en bodelning mellan efterlevande make och dödsboet. DWhen a person passes away, an estate takes form which includes all the deceased’s assets and liabilities. Normally the estate is being taken care of by the parties to the estate. The parties to the estate is everyone who has a rightful claim on the estate, either by heritage according to Swedish law or according to a will from the deceased. Sometimes a division of the joint property between the sp
Nibe Industries has grown from being a local Swedish company to a global group with subsidiaries around the world. Nibe has protected its roots and still retains the head office in Markaryd, where they invest heavily in production locally (Nibe Industrier AB, 2020). The master thesis was conducted at the subsidiary Nibe AB in Markaryd within Climate Solutions” business area with a special focus on
Den 1 januari 2020 infördes bestämmelsen om sabotage mot blåljusverksamhet i brottsbalken. Med blåljusverksamhet avses polisen, räddningstjänsten och ambulanssjukvården. Det har runtom i landet skett olika typer av angrepp riktade mot blåljusverksamheten, bland annat stenkastning. Syftet med bestämmelsen är att skapa ett heltäckande skydd för blåljusverksamheten, då den har en viktig samhällsfunkt
The effects of nitrogen (N) fertilization (0-150 kg N ha(-1) year(-1) since 1865) and pH (3.3-7.4) on fungal and bacterial growth, biomass and phospholipid fatty acid (PLFA) composition were investigated in grassland soils from the 'Park Grass Experiment', Rothamsted Research, UK. Bacterial growth decreased and fungal growth increased with lower pH, resulting in a 50-fold increase in the relative
