A Review of the Combination of Experimental Measurements and Fibril-Reinforced Modeling for Investigation of Articular Cartilage and Chondrocyte Response to Loading

The function of articular cartilage depends on its structure and composition, sensitively impaired in disease (e. g. osteoarthritis, OA). Responses of chondrocytes to tissue loading are modulated by the structure. Altered cell responses as an effect of OA may regulate cartilage mechanotransduction and cell biosynthesis. To be able to evaluate cell responses and factors affecting the onset and prog

Small bowel obstruction: early parameters predicting the need for surgical intervention

To study and identify early clinical and radiological findings that could help to predict operative intervention for small bowel obstruction. One hundred and nine consecutive patients with small bowel obstruction who underwent small bowel follow-through examination with Gastrografin(A (R)) during 2005-2006. The patients were divided into an operative group and a non-operative group, n = 44 and 65,

Studies of chloride binding in concrete exposed in a marine environment

The concentrations of ''free'' chloride and hydroxide ions in extracted pore solution from concrete exposed and submerged in a marine field station were studied by the pore solution expression method. In addition, the corresponding concentrations of total acid soluble chloride in the concrete was analyzed. The relationship between total and free chlorides was analyzed and compared with similar dat

På samma scen. Om samarbete mellan amatör- och yrkesteater. Exemplet Huskvarna.

On the same stage is a case study showing the co-operation between amateurs and professionals in a play called Bara tusen korta år (Just a Thousand Short Years) by Alf Henrikson (1905-1995). Performances were given in the summers of 1994 ? 1998 in Huskvarna. The amateurs were from Huskvarna while the professionals were employed by the regional theatre in Jönköping. When investigating this project

Power-relational core-periphery structures : Peripheral dependency and core dominance in binary and valued networks

With origins in post-war development thinking, the core-periphery concept has spread across the social and, increasingly, the natural sciences. Initially reflecting divergent socioeconomic properties of geographical regions, its relational connotations rapidly led to more topological interpretations. In today's network science, the standard core-periphery model consists of a cohesive set of core a

On the possible role of thiol groups in the insulin-releasing action of mercurials, organic disulfides, alkylating agents, and sulfonylureas

The thiol activity of pancreatic islets was spectrophotometrically assayed as the formation of 6-mercaptonicotinic acid from the organic disulfide, 6, 6’-dithiodinicotinic acid. Islets containing more than 90% β-cells were microdissected from non-inbred oblob-mice. Comparisons of intact with homogenized islets indicated that the organic disulfide penetrates relatively slowly into the β-cells. When

Malignant lymphoproliferative diseases in occupations with potential exposure to phenoxyacetic acids or dioxins : A register‐based study

The Swedish Cancer Environment Register (CER) is a linkage of census data (e.g., on occupations) with the Swedish Cancer Register. It has been used in different studies to generate hypotheses on occupational risk factors for malignant tumors. In this study the risk for malignant lymphoma and multiple myeloma in occupations with potential exposure to phenoxyacetic acids or other related substances

Selective oxidation of benzyl alcohols with molecular oxygen as the oxidant using Ag-Cu catalysts supported on polyoxometalates

We report an efficient process for the oxidation of benzyl alcohols using molecular oxygen as the oxidant catalyzed by Ag-Cu catalysts supported on polyoxometalates (Ag-Cu/POM). The Ag-Cu/POM catalyst was prepared by galvanic displacement in the presence of polyvinyl pyrrolidone and polyethylene glycol. The catalysts were characterized using Fourier transform infrared spectroscopy (FTIR), ultravio

Signal quality assessment of a novel ecg electrode for motion artifact reduction

Background: The presence of noise is problematic in the analysis and interpretation of the ECG, especially in ambulatory monitoring. Restricting the analysis to high-quality signal segments only comes with the risk of excluding significant arrhythmia episodes. Therefore, the development of novel electrode technology, robust to noise, continues to be warranted. Methods: The signal quality of a nove

”Jag ser till att bli uppfattad som en vanlig DDR-medborgare”: musikforskaren Gerd Schönfelder, Kungl. Musikaliska akademien och Stasi

This article is a case study of the contacts between the music sector in Sweden and the GDR in the 1970s, 1980s and 1990s. The case is the activities of the East-German musicologist and music administrator Gerd Schönfelder (1936–2000) in Sweden at that time, and the debate that arose in the early 1990s when he was accused of having worked for the East German security service, Stasi. The purpose is

Strengthened workplace relationships facilitate recovery at work – qualitative experiences of an intervention among employees in primary health care

Background: The literature on workplace interventions focusing on recovery is scarce; hence this study intends to expand that knowledge. An intervention was run for one year, aiming at increasing the experience of recovery during the workday among primary health care employees. During the intervention, different forms of recovery activities were integrated into the daily work at six primary health

Assessment of future EV charging infrastructure scenarios for long-distance transport in Sweden

Over the last two decades, electrification has gained importance as a means to decarbonise the transport sector. As the number of Electric Vehicles (EVs) increases, it is important to consider broader system aspects as well, especially when deciding the type, coverage, size and location of the charging infrastructure required. This article proposes a new approach using agent-based simulations to a

Equilibria and Systemic Risk in Saturated Networks

We undertake a fundamental study of network equilibria modeled as solutions of fixed-point equations for monotone linear functions with saturation nonlinearities. The considered model extends one originally proposed to study systemic risk in networks of financial institutions interconnected by mutual obligations. It is one of the simplest continuous models accounting for shock propagation phenomen

Lawrence Summers Deserves a Nobel Prize for Reviving the Theory of Secular Stagnation

Lawrence Summers produced a big upset within the economics profession when he revived Alvin Hansen’s theory of secular stagnation, which had been thought of as an old-Keynesian fallacy. While some economists like Brad DeLong and Paul Krugman instantly recognized Summers’s contribution, a large share of the economics profession remained skeptical at first. Whereas most New Keynesian models allow fo

Occupational value outcomes among people with mental health issues participating in activity-based interventions–The importance of internal and external factors

Background: Perceived occupational value is an important treatment outcome but is still relatively unexplored as a phenomenon. Aim: To evaluate whether the Balancing Everyday Life (BEL) intervention for people with mental health issues was effective compared to Standard Occupational Therapy (SOT) regarding improvement on three dimensions of occupational value (concrete, socio-symbolic and self-rew

Blood-based biomarkers for Alzheimer's disease

Neurodegenerative disorders such as Alzheimer's disease (AD) represent a mounting public health challenge. As these diseases are difficult to diagnose clinically, biomarkers of underlying pathophysiology are playing an ever-increasing role in research, clinical trials, and in the clinical work-up of patients. Though cerebrospinal fluid (CSF) and positron emission tomography (PET)-based measures ar

The consequences of timing norms and term limits on local agency

Incorporating time as a unit of analysis can enrich the study of agency by showing the specific ways in which actors are temporally constrained when responding to economic disturbances. In this paper, this is done by examining how the behavior of actors is affected by timing norms such as term limits that may be associated with an actor's position, as for example, an elected mayor or university vi

Rate of MIMO Systems with CSI at Transmitter and Receiver from Pilot-Aided Estimation

We consider realistic multiple input multiple output antenna systems operating over spatially colored channels with instantaneous, albeit imperfect, channel state information at the receiver and only covariance knowledge available at the transmitter. We focus on pilot-aided channel estimation in which the receiver uses minimum mean square error channel estimation. For such a setup, our goal is the
