Characterization of supermacroporous monolithic polyacrylamide based matrices designed for chromatography of bioparticles

Supermacroporous monolithic acrylamide (AAm)-based cryogels were prepared by radical cryo-polymerizaton (polymerization in the moderately frozen system) of AAm with functional monomers and cross-linker N,N'-methylene-bis-acrylamide (MBAAm). Electron microscopy studies revealed supermacroporous structure of the developed cryogels with pore size of 5-100 mum. Cryogel porosity depended on cryo-polyme

Hydrocarboxylation of olefins using an amphiphilic palladium catalyst, activity and recycling properties NMR identification of some reaction intermediates

The high solubility in acidic solutions of N-bis(N',N'-diethyl-2-aminoethyl)-4-aminomethylphenyl-diphenylphosphine (N3P) make it a suitable candidate for study and comparison to the more commonly studied trisulfonated triphenylphosphine (TPPTS) ligand in the palladium catalysed aqueous hydrocarboxylation reaction. The catalyst employing N3P shows an inverted regioselectivity compared to the TPPTS

Swedish Primary School Pupils' Inter-ethnic Relationships

The aim of the Swedish educational policy is educational participation and academic achieivement for all children, irrespective of ethnic background. Majority language instruction is an important tool used to achieve this goal. We argue that taking lessons in Swedish-as-a-second-language (S2) sets children apart in their class and limits their possibilities to interact with Swedish children and th

Staples, Institutions and Growth. Competitiveness of Guatemalan Exports 1524-1945

Popular Abstract in Swedish Avhandlingen analyserar Guatemalas råvaruexport under perioden 1524-1945.In the integrated institutional-staples-‘vent for surplus’ approach, the opening of trade occurs because of initial demand. Once demand is determined, competitiveness is a function of transportation costs, entrepreneurship, capital, land and labour costs, as well as the role played by the State. When all these factors promote competitiveness within an institutional framework that decreased transac

Cross-bridge behaviour in skinned smooth muscle of the guinea-pig taenia coli at altered ionic strength

1. The effects of varied levels (25-300 mM) of ionic strength on mechanical properties and ATP hydrolysis rate of chemically skinned guinea-pig taenia coli fibres were investigated. 2. The tension development following activation by calcium (pCa 4 8), and relaxation following removal of calcium (pCa 9), were slower in 25 mm compared to 150 mm ionic strength. In fibres activated by thiophosphorylat

Risk of second cancer in Hodgkin lymphoma survivors and influence of family history

Purpose: Although advances in Hodgkin lymphoma (HL) treatment have led to improved disease-free survival, this has been accompanied by an increased risk of second cancers. We sought to quantify the second cancer risks and to investigate the impact of family history. Patients and Methods: Using the Swedish Family-Cancer Project Database, we identified 9,522 individuals with primary HL diagnosed bet

Ethnic density, urbanicity and psychosis risk for migrant groups - A population cohort study

Background: Rates of psychotic disorder are raised for many migrant groups. Understanding the role played by the social context in which they live may help explain why. This study investigates the effect of both neighbourhood ethnic density and urbanicity on the incidence of non-affective psychosis for migrant groups. Method: Population based cohort of all those born 1965 or later followed from th

Influenza A virus evolution and spatio-temporal dynamics in eurasian wild birds : A phylogenetic and phylogeographical study of whole-genome sequence data

Low pathogenic avian influenza A viruses (IAVs) have a natural host reservoir in wild waterbirds and the potential to spread to other host species. Here, we investigated the evolutionary, spatial and temporal dynamics of avian IAVs in Eurasian wild birds. We used whole-genome sequences collected as part of an intensive long-term Eurasian wild bird surveillance study, and combined this genetic data

Linear reaction norms of thermal limits in Drosophila : Predictable plasticity in cold but not in heat tolerance

* Thermal limits of ectotherms have been studied extensively and are believed to be evolutionarily constrained, leaving ectotherms at risk under future climate change. Phenotypic plasticity may extend the thermal limits, but we lack detailed characterizations of thermal limit reaction norms as well as an understanding of the interspecific variation in these reaction norms. * Here, we investigated

Health Economic Analysis of Open and Robot-assisted Laparoscopic Surgery for Prostate Cancer Within the Prospective Multicentre LAPPRO Trial

Background: The rapid adoption of robot-assisted laparoscopy in radical prostatectomy has preceded data regarding associated costs. Qualitative evidence regarding cost outcomes is lacking. Objective: This study assessed how costs were affected by robot-assisted laparoscopic prostatectomy (RALP) compared with open surgery. Design, setting, and participants: Cost analysis was based on the dataset of

High water intake and low urine osmolality are associated with favorable metabolic profile at a population level : low vasopressin secretion as a possible explanation

Purpose: Elevated plasma concentration of the vasopressin marker copeptin and low water intake are associated with elevated blood glucose and diabetes risk at a population level. Moreover, in individuals with low urine volume and high urine osmolality (u-Osm), water supplementation reduced fasting plasma (fp) copeptin and fp-glucose. In this observational study, we investigated if low total water

Systemic necrotizing vasculitides in severe alpha1-antitrypsin deficiency

We describe the clinical presentation and outcome in a series of eight patients with systemic necrotizing vasculitis and severe alpha1-antitrypsin (AAT) deficiency followed up at three Swedish hospitals during 1968-92. We also review six other cases reported in the literature during the same period. Diagnosis of severe AAT deficiency was based on the presence of the PiZZ phenotype, or low plasma t

Land cover data of Upper Parana River Basin, South America, at high spatial resolution

This study presents a new land cover map for the Upper Paraná River Basin (UPRB-2015), with high spatial resolution (30 m), and a high number of calibration and validation sites. To the new map, 50 Landsat-8 scenes were classified with the Support Vector Machine (SVM) algorithm and their level of agreement was assessed using overall accuracy and Kappa coefficient. The generated map was compared by

On the Use of Rotational CARS on Polyatomics and in Time Domain

This thesis work concerns the further developments of dual-broadband rotational coherent anti-Stokes Raman spectroscopy (RCARS) through experimental and theoretical investigations. Rotational CARS is an established technique for gas-phase thermometry and concentration measurement with major applications in combustion diagnostics. The technique has previously mainly been applied on species with lin

Container-based Continuous Delivery for Clusters

The focus of this master’s thesis was aimed at E.ON’s electricity saving project, 100koll, in collaboration with IT-consulting firm Data Ductus.The 100koll users demand high availability, which creates a complex underlaying system-infrastructure. The processes of deploying and preparing new releases to the system is presently done manually. Data Ductus is requesting an investigation on whether or

Ventilationseffektivitet i kontorsmiljö - En jämförelse av deplacerande och omblandande ventilation ur termisk komfort

Today there is a high focus on the energy use when constructing new buildings. This mainly depends on the increased regulations and energy classifications that have been issued. Because of this, studies have shown that mechanical cooling in office environments leads to high energy consumption and service costs. This has led to an increased interest in analyzing if cooling only through ventilation

Linking Rules Assessed Against European and National Legal Benchmarks - A Juridical Remedy to Mitigate Double Non-Taxation?

This thesis provides a comprehensive analysis of linking rules, which were adapted as one of the alleged remedies against base erosion by the EU and the OECD. A number of issues emerge in connection with those recommended rules. This thesis will thus assess compliance of those rules against domestic and European legal benchmarks. German national law will serve as an example of domestic integration
