A new approach to detection of antigen-antibody complexes by microcalorimetric measurements of heat production in blood cells

Using batch microcalorimeters of the thermopile conduction type, heat production was measured in human blood in the presence of defined antigens and their specific antibodies. A large increase in heat production, reflecting increased metabolic activity in the blood cells, was found when antigens and specific antisera at certain antigen-antibody proportions were mixed with the blood. The reproducib

The effects of cyclophosphamide on in vitro correlates of tumor immunity

The effects of cyclophosphamide (CY) on tumor immunity against isografts of rat sarcomas induced by polyoma virus were studied using in vitro techniques. Groups of sarcoma‐bearing animals received CY (250 mg/kg intraperitoneally 11 days after isografting) CY (150 mg/kg IP 8 days after isografting), or IP injections of 0.9% NaCl. In control rats tumor growth was progressive. All CY‐treated animals

Surface functionalization of III-V Nanowires

The physical and chemical properties of semiconductor nanowires are significantly influenced by their surface structure and morphology. This can be understood in that surfaces make out a much larger part of the total structure as compared to macroscale objects. An immediate consequence is that the lack of surface control can result in poor performance and reproducibility of any nanowire device. It

Workplace Incivility : Investigating bystander behavior, well-being, and coping responses to perceived incivility

Ohövliga beteenden har visats vara ett vanligt förekommande fenomen, med negativa effekter för individer, organisationer och samhället. Under de senaste två decennierna har omfattande forskningsfokus lagts på att öka kunskapen kring ohövlighet i arbetslivet, bland annat genom att undersöka utsatta, och utövare av ohövlighet. Trots detta så har färre studier undersökt hur ohövliga beteenden påverkaWorkplace incivility has been found to be a ubiquitous phenomenon, with adverse effects for individuals, organizations and society. Over the past two decades, substantial research efforts have been made to increase knowledge about workplace incivility, including investigations of its targets and perpetrators. However, less research has been conducted on how workplace incivility impacts bystanders.

Fundamental limitations of case isolation

Case isolation is a strategy with the potential to curb infectious disease epidemics. Expressions for the stability boundary of a case isolation scheme defined through the proportion of the infectious population that it isolates with a given delay have recently been established. Here we quantify how this stability boundary moves when heterogeneity of the inter-individual contact network increases,

Samverkansmeritering - förutsättningar, behov och möjligheter : Rapport: MERSAM-Meritvärde av samverkansskicklighet

Samverkansuppgiften har gradvis fått en tydligare roll sedan mitten av 1990-talet och är idag en nödvändig och central uppgift för högskolor och universitet i Sverige, inte minst för att hantera vår tids samhällsutmaningar. Det finns få tecken på att denna utveckling kommer att vända och det är därför viktigt att vi inom sektorn för en dialog kring hur vi tar oss an och värderar det arbete som ske

Varför är det så snårigt? Begrepp relaterade till samverkansmeritering

Detta dokument är framtaget som en intern rapport inom MerSam – Meritvärde av samverkansskicklighet, vars projekttid löpt under 2017 – 2020. MerSam är ett av Vinnovas 17 finansierade K3-projekt. Rapporten utgör en sammanställning av insamlad information från dokument, dialoger, workshoppar, intervjuer och enkäter. Rapporten visar på användning av begrepp och tolkning av begrepp. Syftet är att besk

Reference models for concurrent engineering implementation in individual, serial and mass production

Application of concurrent engineering (CE) to product development process (PDP) has to consider the type of production (individual, serial, mass), product complexity and level of design: original, innovative, variation and adaptive. Systematic analyses of product development processes, workflows, data and project management, in various companies, has shown that specific criteria have to be fulfill

Investing into climate change mitigation despite the risk of failure.

In order to convince both policy makers and the general public to engage in climate change mitigation activities, it is crucial to communicate the inherent risks in an effective way. Due to the complexity of the system, mitigation activities cannot completely rule out the possibility of the climate reaching a dangerous tipping point but can only reduce it to some unavoidable residual risk level. W

Exterior auralization of traffic noise within the LISTEN project

In the present paper, computational auralizations of a single pass-by of a passenger car and passenger train are investigated. Auralization of future traffic noise scenarios would be a valuable tool for city planners, noise consultants and decision makers, since it would make it possible to evaluate various noise mitigation solutions already at the planning stage. The main goal of the Swedish mult

Longitudinal Imaging Using PET/CT with Collagen-I PET-Tracer and MRI for Assessment of Fibrotic and Inflammatory Lesions in a Rat Lung Injury Model

Non-invasive imaging biomarkers (IBs) are warranted to enable improved diagnostics and follow-up monitoring of interstitial lung disease (ILD) including drug-induced ILD (DIILD). Of special interest are IB, which can characterize and differentiate acute inflammation from fibrosis. The aim of the present study was to evaluate a PET-tracer specific for Collagen-I, combined with multi-echo MRI, in a

More than protection : The function of TiO2interlayers in hematite functionalized Si photoanodes

Worldwide significant efforts are ongoing to develop devices that store solar energy as fuels. In one such approach, solar energy is absorbed by semiconductors and utilized directly by catalysts at their surfaces to split water into H2 and O2. To protect the semiconductors in these photo-electrochemical cells (PEC) from corrosion, frequently thin TiO2 interlayers are applied. Employing a well-perf
