The thermoresponsive copolymer of N-isopropylacrylamide (NIPAM) with 1-vinylimidazole (VI), poly(NIPAM-VI), synthesized by radical polymerization has been used to purify the histidine-tagged green flourescent protein (His-tag GFP) from recombinant E. coli by metal-chelate affinity precipitation. The purified protein was immobilized on the BIAcore sensor chip by carbodiimide coupling. Affinity bind

Aim. The purpose of this investigation was to analyze predictors for wound healing, amputation and mortality after vacuum assisted closure (VAC (R)) therapy of wounds in the lower limb in patients with arterial disease. Methods. One hundred and twenty one wounds were treated and followed for 12 months at two vascular centres in Uppsala and Malmo, Sweden. VAC (R) therapy was applied in the wound at

The co-adsorption of Cd(II) and glyphosate (N-(phosphonomethyl)glycine, PMG) at the manganite (gamma-MnOOH) surface has been studied in the pH range 6-10 at 25 degrees C and with 0.1 M Na(Cl) as ionic medium. Batch adsorption experiments, Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS) and extended X-ray absorption fine Structure (EXAFS) spectroscopy were use

This paper reports the findings of a global survey of practice patterns for the management of patients with haemophilia A. A total of 147 haemophilia treatment centres worldwide responded to the questionnaire, supplying data for 16 115 patients with haemophilia A. From these responses, 38% (range: 25-48%) of patients were under 18 years old. Almost half (47%) of patients were reported to have mild

The purpose of the present study is to assess QT-interval measurements from the EASI 12-lead electrocardiogram (ECG) as compared with the standard 12-lead ECG. The QT interval was automatically determined in simultaneously recorded standard and EASI 12-lead ECGs, using a validated wavelet-based delineator. The agreement between the 2 sets of measurements was quantified both on a lead-by-lead basis

The native bee fauna provides an important ecosystem function, but a large proportion of this fauna in Europe is threatened as a result of habitat loss and fragmentation. The solitary bee Andrena hattorfiana is specialised on collecting pollen from the plant-family Dipsacaceae. In northern Europe the major pollen resource is the insect-pollinated herb Knautia arvensis. We quantified the available

Analys av immunteknologis MUTZ-3 visar tecken på genetisk drift Allergi är en vanligt förekommande sjukdom som drabbar en stor del av befolkningen. Sjukdomen kan ta många olika former och vanliga typer är matallergi, luftvägsallergi och kontaktallergi. Kontaktallergi uppstår när en person kommer i upprepad kontakt med kemikalier som kan aktivera immunförvaret. Immunförsvarets är ett komplext nätveThe continued increased exposure to chemicals and the increasing prevalence of allergic contact dermatitis makes it important to develop accurate testing methods and strategies to assess chemical sensitizers. The Genomic Allergen Rapid Detection (GARD) assay is an in vitro test method that uses the transcriptional response of a myeloid cell line, MUTZ-3, after exposure to test substances to assess

Memory integration is how series of similar memories can merge into overlapping representations as one abstract model of behavior to anticipate present and future episodes – facilitating instrumental use of episodic experience for higher-order inferences. Previous research has showed that a novel memory of reward can travel backwards in time through episodic memory and generalize its contents to p

The aim of our study was to examine the relationship between creativity and wellbeing. The material for our study has been gathered through a questionnaire with self-assessment at one of Scandinavia's largest companies in the hotel industry. The questionnaire consisted of The organisational questionnaire (GEFA) and The measurement of wellbeing. In the study 90 questionnaires was distributed in

Massive MIMO has attracted many researchers’ attention as it is a promising technology for future 5G communication systems. To characterize the propagation channels of the massive MIMO and to evaluate system performance, it is important to develop an accurate channel model for it. In this thesis, two correlative models, i.e., the Kronecker model and the Weichselberger model, and a cluster-based m

Franchising är egentligen ett företagsekonomiskt begrepp vars avtal berör många rättsområden såsom konkurrensrätt, avtalsrätt, immaterialrätt samt arbetsrätt. Det en verksamhetsform som kombinerar ett lyckat beprövat affärskoncept med egenföretagande. Det är en specialform av ett återförsäljaravtal, men bör enligt EU-domstolens avgörande i mål C-161/84 Pronuptia de Paris, inte räknas som en distriFranchising is an economic concept in business law, which relates to several legal areas of law such as competition law, contract law, intellectual property law and labor law. It is a business strategy, which combines a successful proven business concept with selfemployment. Franchising is a special form of a reseller agreement, but should, according to the judgment from the EU Court of Justice in

På senare år har polisen i Sverige börjat använda sig av spårhundar i sitt arbete för att säkra biologiska spår vid brottsplatser. En hund har tusen gånger mer känsligt luktsinne än människan vilket betyder att hundar kan hitta små biologiska spår, ofta blandade med jord, som är omöjliga för människan att se med blotta ögat. Det ökande användandet av spårhundar har lett till att fler biologiska prThe aim of the project was to investigate and evaluate different extraction methods for detection of human DNA in environmental crime scene samples containing soil. Soil is a complex and heterogeneous material consisting of several inhibitory compounds, which makes it difficult to extract DNA from such samples. The investigation included the evaluation of 19 different extraction methods based on s

Abstract Metal oxide semiconductor (MOS) capacitor was fabricated on the InGaAs substrate with Al2O3/HfO2 gate oxide. InGaAs is one of the promising candidates for advanced applications which require the lower power supply and high frequency. The high-k films (Al2O3/HfO2) were formed by atomic layer deposition (ALD) as an alternative to silicon dioxide (SiO2) to proceed the scaling of oxide to low

Simulering kan förbättra hanteringen av järnvägsstörningar Förseningar i järnvägssystemet kostar årligen såväl industrin som samhället miljardbelopp. Därför är det viktigt att minimera tiden som ett tåg står stilla efter en störning, som till exempel ett kontaktledningsbrott eller en personpåkörning. I examensarbetet presenteras en simuleringsmodell som kan användas som ett verktyg för att hitta Within the Swedish rail network, maximum track capacity is reached on multiple sections with costly delays as a result. Therefore minimizing the time a train is stationary after a disruption such as overhead line damage or suicide is important. Prior work has mapped stakeholders within the management of the two scenarios, but due to complexity, finding effective means of improvement is difficult.

Skalning och modellering av en kromatografikolonn för rening av sockerlösningar. För att uppnå klimatmålen behöver fossila råvaror inom kemiindustrin bytas ut mot förnybara råvaror. Socker är en råvara med stor potential inom industrin, men är ofta förorenat med salter. Därför utforskas rening av sockerlösningar här. För att använda socker som förnybar råvara för kemiindustri behöver sockret oftaTo utilize sugars as a feedstock for renewable industries, the feedstock often needs to be very pure. This is due to ionic species contaminating the sugar feedstock being potent catalyst poisons in many cases. To remove ionic species from the sugar feedstock, it is dissolved and purified using packed ion-exchange columns. In this report, a lab-scale setup of a large scale ion-exchange setup was co
