Popular Abstract in Swedish För att styra, övervaka och utvärdera processer inom processindustrin, samlas stora mängder data från mätgivare i olika delar av processen. Den tekniska utvecklingen inom mätteknik- och datorområdet har gjort det möjligt att mäta många olika storheter. Inom processindustrin kan antalet vara mycket stort; hundratals och ibland tusentals värden loggas kontinuerligt med inIn this work, various aspects of multivariate monitoring and control of wastewater treatment operation are discussed. A number of important difficulties face operators and process engineers when handling online measurements from wastewater treatment processes. These include, for instance, a high number of correlated measurement variables, non-stationarities, nonlinearities and multiscale process b

The paper discusses how the early reception in Swedish of the Aesopic fable was filtered through German Lutheranism. The main focus of the paper is on the country’s very first vernacular fable collection, Hundrade Esopi Fabler (A Hundred Fables of Aesop), published in Stockholm in 1603. This volume is a faithful translation of the German collection Hundert Fabeln aus Esopo, composed in the 1570s b

This paper shows a robust and easily implemented clock generator for custom designs. It is a fully digital design suitable for both high-speed clocking and low-voltage applications. This clocking method is digital, and it avoids analog methods like phase locked loops or delay line loops. Instead, the clock generator is based on a ring counter which stops a ring oscillator after the correct number

The theme of this thesis is to study discretizations of nonlinear dissipative evolution equations, which arise in e.g. advection-diffusion-reaction processes. The convergence analysis is conducted by first considering an abstract time discretization of the problem, which enables a decoupling of the time and spatial approximations, and secondly by introducing the spatial discretization as an evolut

Albeit there is a general consensus that urban design in the twentieth century failed in relation to space use, systematic research on this aspect has been very limited or at most inadequate in the developing countries. This study focuses on the above failure of urban design in this century with specific reference to the developing countries through an analysis of Dar es Salaam city centre, Tanzan

During B and T cell differentiation and proliferation many genes are induced or repressed while certain genes are constitutively expressed. To investigate processes related to B and T cell activation, the gene expression of stimulated and nonstimutated Ramos and Jurkat cells was studied using cDNA microarray technology. Simultaneous analysis of close to 600 genes indicated highest increase in the

Hematopoietic stem cells (HSCs) are primitive tissue-specific somatic stem cells, responsible for the maintenance and replenishment of the bone marrow (BM) and subsequently the entire blood system. The never-ending ability to differentiate into all the mature hematopoietic lineages makes these HSCs attractive candidates for use in future regenerative medicine. HSCs are balanced between different f

The 21+ isomer in 94Ag has recently been reported to have a two-proton decay branch to 92Rh. We have populated 92Rh through the 40Ca(58Ni,alphapn) reaction at 240 MeV, and have performed detailed spectroscopic measurements of the levels, finding new states and measuring angular distributions of gamma rays. We find no evidence for the states reported to be populated by the two-proton decay of 94Agm

Dispossession and displacement have made their imprint on the lives of uncounted millions, and continue to pose the gravest threat to security for many more. The ascent of neoliberalism to global hegemony in recent decades – in all its multifarious and contextually path-dependent varieties – has radically changed the landscape of human vulnerability and security. Its successes in massive global an

Wear in forming tools and contact problems between sheet-metal and tool-material are common problems in manufacturing industries and sheet-metal-parts production. In this paper recent tool material experiences are presented. Quantitative determination of wear has been performed using micro hardness indentions made on the tool surface prior to pressings and thereafter measured. Wear tests are perfo

Purpose: To provide guidelines for all surgical specialists who deal with the open abdomen (OA) or the burst abdomen (BA) in adult patients both on the methods used to close the musculofascial layers of the abdominal wall, and regarding possible materials to be used. Methods: The guidelines were developed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach

Historical commons represent self-governed governance regimes that regulate the use and management of natural and man-made shared resources. Despite growing scientific interests, analyses of commons evolution and temporal dynamics are rare and drivers of change (birth, adaptation, dissolution) remain obscure. We apply an interdisciplinary approach and address these issues from an eco-evolutionary

Given a network of receivers and transmitters, the process of determining their positions from measured pseudoranges is known as network self-calibration. In this paper we consider 2D networks with synchronized receivers but unsynchronized transmitters and the corresponding calibration techniques, known as Time-Difference-Of-Arrival (TDOA) techniques. Despite previous work, TDOA self-calibration i

Background: The impact of obesity on patient-reported outcome (PRO) after total knee arthroplasty (TKA) surgery has demonstrated varying results. We evaluated knee pain, Activity in Daily Life function (ADL), and satisfaction after TKA surgery in patients with and without prior bariatric surgery (BS). Methods: Scandinavian Obesity Surgery Registry (SOReg) and the Swedish Knee Arthroplasty Register

New applications of a flow-calorimetric biosensor system, the enzyme thermistor (ET) are described. The ET measures the reaction heat in a small column containing immobilized biocatalyst as a temperature change of the effluent from the column. Since most biological reactions are exothermic, the ET has a very broad applicability and numerous assays of clinical as well as biotechnological interest h

Tetrapod-shaped CdSe(core)/CdTe(arms) colloidal nanocrystals, capped with alkylphosphonic acids or pyridine, were reacted with various small molecules (acetic acid, hydrazine and chlorosilane) which induced their tip-to-tip assembly into soluble networks. These networks were subsequently processed into films by drop casting and their photoconductive properties were studied. We observed that films
