This essay investigates the impact of income inequality on economic growth in developed countries. The link is primarily investigated through the possible influence of income inequality on the four growth channels savings, human capital, population growth and labor force productivity. A theoretical model, based on an extended version of the Romer model, is presented, where a higher degree of incom
The objective was to study ambulatory blood pressure and heart rate variability between day and night in patients with type 1 (insulin-dependent) diabetes mellitus with different degrees of diabetic nephropathy, and to evaluate the influence of autonomic neuropathy and type of antihypertensive treatment. Twenty type 1 diabetic patients with diabetic nephropathy and antihypertensive treatment were
The World Health Organization (WHO) classification of myeloid leukaemia was revised in 2008. It incorporates newly recognized entities and emphasizes the pivotal role of cytogenetic abnormalities. The aim of this study was to evaluate the usability of the WHO classification when applied to a large population-based paediatric acute myeloid leukaemia (AML) cohort. We included children diagnosed with
A numerical study has been carried out for slot jet impinging on flat and concave surfaces. Five turbulence models are employed for the predictions of these strongly strained turbulent flows, namely linear eddy viscosity model (LEVM), low-Re explicit algebraic Reynolds stress model (EASM) and three different V2F models. A bounded formulation for Cμ was also introduced to account for the better pre
A recent study of ours suggested that the very presence of a Teachable Agent (TA) from a mathematics learning game might affect students’ test performance when the TA reappeared in the margin of a regular, digital math test. We hypothesized that this effect, which seemed to particularly target low-achievers, was due to the students’ mindset changing from that of “taking a test” to that of “teachin
Decisions regarding strategic software process improvement (SPI) are generally based on the management's viewpoint of the situation, and in some cases also the viewpoints of some kind of an SPI group. This may result in strategies, which are not accepted throughout the organisation, as the views of how the process is functioning are different throughout the company. This paper describes a method f
Popular Abstract in Swedish Malmö erbjuder speciellt goda möjligheter till epidemiologiska studier, därför att all sjukhusbunden vård erbjuds av ett enda sjukhus som dessutom i stort sett endast täcker Malmös egna behov. Därtill kommer att nu avlidne professor Folke Linell redan under 1950-talet insåg den stora betydelsen för sjukvårdens kvalitet av en omfattande obduktionsverksamhet. Under periodIn the present thesis incidence, survival, mortality, cure and prognosis in invasive breast cancer in Malmö was studied over a 30 year period. Validated data from the Cancer Registry and the Cause of Death Registry were used. In the process of validation systematical biases were identified in both registers. The incidence increased over time and was strongly related to increases in diagnostic acti
Popular Abstract in Swedish Helicobacter pylori är troligen världens vanligaste bakterieinfektion och mer än 50% av jordens befolkning är infekterad. Bakterien orsakar kronisk magkatarr vilket kan utvecklas till sår både i magsäcken och i tolvfingertarmen, samt till magcancer. Behandling med antibiotika, som dödar bakterien, och syrahämmande läkemedel har revolutionerat behandlingen av magsår, somThe Gram-negative genus of Helicobacter consists of many bacterial species that colonize a wide range of animal hosts. The genus can be divided into gastric species that colonize the stomach, and enteric species that preferentially colonize the colon and biliary tree of various animal hosts. Helicobacter pylori cause gastritis, gastro-duodenal ulcer disease and gastric adenocarcinoma and lymphoma
Controlling an induction machine has been a difficult task since its invention, especially at low speed operation and during highly dynamic regimes, where the required torque/speed changes constantly. This paper aims to present the validation and implementation of a deadbeat direct torque and flux control scheme (DB-DTFC) for induction machines on a multilevel platform consisting on an FPGA, a rea
Popular Abstract in English N/AAquatic systems worldwide receive large amounts of organic carbon from terrestrial sources. This ‘allochthonous’ organic carbon (AlloOC) affects critical physical and chemical properties of freshwater ecosystems, with consequences for food web structures and exchange of greenhouse gases with the atmosphere. In the boreal region, loadings of AlloOC are particularly high due to leaching from huge or
This paper compares the language Grafcet with the language Grafchart. Both are graphical languages aimed for sequential control applications. Grafcet is aimed for specification of controller structures, i.e., for local level control applications. Grafchart is based on Grafcet, Petri nets and ideas from objectoriented programming and it can be used for any sequential control application, both appli
A Sierpinski-like fractal patch antenna with a slant strip in the first iteration is proposed in this article. The parameters of this kind of antenna are analyzed and optimized for dual WLAN application. The added slant strip provides simple probe feeding for compactness and also helps bandwidth enhancement due to multiple modes, which can be evident from current distribution. Measured return loss
This paper describes a new hardware architecture for binary image erosion and dilation. The design is to be used in a self contained real-time surveillance system. Thus, low complexity and low power consumption are main constraints. To achieve this goal the aim has been to reduce memory requirements and the number of memory accesses per pixel. By storing only the number of consecutive ones that ap
In this study, a fully three-dimensional calculation method has been further developed to simulate and analyze various processes in a thick anode duct. The composite duct consists of a porous layer, the flow duct and solid current connector. The analysis takes the electrochemical reactions into account. Momentum and heat transport together with gas species equations have been solved by coupled sou
Popular Abstract in Swedish Allt eftersom fler och fler organismers totala uppsättning gener, genomet, sekvenseras ökar fokus på att kartlägga de genprodukter, proteiner, som uttrycks. Att kunna studera de proteiner som uttrycks mer eller mindre vid olika tidpunkter eller cellulära tillstånd utgör en viktig del i sökandet efter kunskap om biologiska och medicinska processer. Studier av den totala The study of the protein complement of a genome is called proteomics. Proteomics can be defined as identification, quantification and characterization of a total set of proteins expressed at different time-points or under different cellular states to provide global information about biological processes. The study of membrane proteins is a challenging area in the development of proteomic research.
The paper presents a review of the scientific literature on computer modeling of socio-technical systems. The aim is to briefly review and discuss modeling approaches that are suitable for the simulation of socio-technical systems, specifically in the context of risk and vulnerability analysis of critical infrastructures. It is found that seven main socio-technical modeling approaches can be disce
