Introduction Colon cancer is one of the most common forms of cancer world wide, with an incidence of almost 1 million cases anually. Surgery is a prerequisite for cure and the majority of patients are potentially curable at diagnosis. For a surgical resection to be curative the surgeon needs to remove the tumour together with all affected regional lymph nodes. How extensive the mesenteric resecti

Energy usage and its associated costs have taken on a new level of significance in recent years. Globally, energy costs that include the cooling of server rooms are now comparable to hardware costs, and these costs are on the increase with the rising cost of energy. As a result, there are efforts worldwide to design more efficient scheduling algorithms. Such scheduling algorithm for grids is furth

Popular Abstract in Swedish Dagens vårdsystem står inför många stora utmaningar. Många av dem är relaterade till komplexa vårdbehov hos den allt större andelen sköra äldre personer. Denna andel ökar samtidigt som många vårdorganisationer har krav på sig att minska kostnaderna. Dessa äldre personer har ofta flera sjukdomar samtidigt och de har vanligtvis kontakter med många olika vårdgivare, på fleThe overall aim of this thesis was to investigate healthcare utilisation patterns and to explore the effects of a case management intervention for frail older people on healthcare utilisation and costs in relation to utility. A further aim was to explore the older people’s and case managers’ experiences of the intervention. Study I was a quantitative study comprising ten age cohorts aged between 6

The use of energy gases with renewable origins will become important with diminishing fossil resources. This as the infrastructure of the gaseous fuels is well built out and the distribution networks already exist. LPG is one of the most versatile fuels around, perfect for rural areas and in many other applications. The fossil origin of the fuel will, in today’s climate and environmental debate, h

Sensitive and nonintrusive detection of HCl in reactive gas flows with high spatial and temporal resolution manner has for the first time (to our knowledge) been demonstrated using mid-infrared polarization spectroscopy (IRPS). Trace levels of HCl were prepared in an atmospheric pressure premixed CH4/O-2/Ar flat flame by seeding a small amount of chloroform into the Ar flow. Detection of HCl with

Research paper Purpose To analyze the social organization of LIS using the Nordic countries as example, focusing on organizational setting, research work and relations between LIS and academia as well as the field of professional practice. Design/methodology/approach Based on a framework for analyzing scientific fields, as well as its application on LIS, aspects relating to the impact of contextu

The aim of this study was to determine the effect of dietary supplementation with alpha-ketoglutarate (AKG) sodium salt on growth rate in relation to bone collagen formation during the first 70 d of postnatal life in piglets. The results show that dietary AKG supplementation increased body weight of the experimental piglets in comparison to the controls, especially between 21(st) and 56(th) d of l

The connection between the Fermi surface and charge-density-wave (CDW) order is revisited in 2H-TaSe2. Using angle-resolved photoemission spectroscopy, ab initio band-structure calculations, and an accurate tight-binding model, we develop the empirical k-resolved susceptibility function, which we use to highlight states that contribute to the susceptibility for a particular q vector. We show that

BACKGROUND: There are increasing reports of deaths and serious complications associated with the use of negative pressure wound therapy (NPWT), of which right ventricular heart rupture is the most devastating. The use of a rigid barrier has been suggested to offer protection against this lethal complication by preventing the heart from being drawn up against the sharp edges of the sternum. The aim

Systemic and local inflammation in relation to the resident microbiota of the human gastro-intestinal (GI) tract and administration of probiotics are the main themes of the present review. The dominating taxa of the human GI tract and their potential for aggravating or suppressing inflammation are described. The review focuses on human trials with probiotics and does not include in vitro studies a

Secondary hole-nesting birds that do not construct nest holes themselves and hence regularly breed in nest boxes constitute important model systems for field studies in many biological disciplines with hundreds of scientists and amateurs involved. Those research groups are spread over wide geographic areas that experience considerable variation in environmental conditions, and researchers provide

Vertical arrays of direct band gap III-V semiconductor nanowires (NWs) hold the prospect of cheap and efficient next-generation photovoltaics, and guidelines for successful light-management are needed. Here, we use InP NWs as a model system and find, through electrodynamic modeling, general design principles for efficient absorption of sun light in nanowire arrays by systematically varying the nan

In this paper a controller reduction method for discrete-time linear time-invariant systems is described. Using the bounded-real lemma, the proposed method generates reduced controllers with closed loop stability and H-infinity norm performance guarantee. Information of the full controller is used as a basis for reduction using singular value decomposition. This is different from traditional model

The Arctic cryosphere is a critically important component of the earth system, affecting the earth's energy balance, sea level, greenhouse gases and atmospheric circulation, transport of heat through ocean circulation, ecology and human resource use and well-being. The Arctic cryosphere is, however, changing rapidly with multiple important consequences that will potentially affect the earth system

We present an analysis and demonstration of few-cycle ultrashort laser pulse characterization using second-harmonic dispersion scans and numerical phase retrieval algorithms. The sensitivity and robustness of this technique with respect to noise, measurement bandwidth and complexity of the measured pulses is discussed through numerical examples and experimental results. Using this technique, we su
