Effective material parameters for diffusion and elastic deformation are calculatedfor porous materials using a continuum theory-based superposition procedure. The theory that is limited to two-dimensional cases, requires that the pores are sufficiently sparse. The methodleads to simple manual calculations that can be performed by, e.g. hospital staff at clinicaldiagnoses of bone deceases that invo
Design and properties are reported for a novel type of multi-channel isothermal microcalorimeter. It is equipped with 48 calorimetric units (channels) and is primarily intended for use as a monitor of the activity of living cells, tissues and small animals. Calorimetric vessels are positioned in a holder with the format of a 48-well microtiter plate. At most, 47 samples can be measured simultaneou
The issue of lag selection in ADF unit root testing is important, even asymptotically, for if the number of lags is not allowed to increase at a certain rate the test might not be correctly sized. However, size control is not the only concern. Indeed, simulations have repeatedly shown how increasing lag lengths tend to be associated with reductions in power, thus adding to the well-known low power
The aim of this paper is to describe, conceptualise and critically discuss how and with what consequences marketing is used to construct a mass market for vegan substitutes. Drawing on the concepts of the marketing device and qualification, it shows how Oatly – a Swedish company making oat-based products – enrols three sets of marketing devices, i.e. digital media, packaging and stores, to simulta
Increased research is being driven by the automotive industry facing challenges, requiring to comply with both current and future emissions legislation, and to lower the fuel consumption. The reason for this legislation is to restrict the harmful pollution which every year causes 3.3 million premature deaths worldwide [1]. One factor that causes this pollution is NOx emissions. NOx emission legisl
This paper presents the test results of the second prototype of SAMPA, the ASIC designed for the upgrade of read-out front end electronics of the ALICE Time Projection Chamber (TPC) and Muon Chamber (MCH). SAMPA is made in a 130 nm CMOS technology with 1.25 V nominal voltage supply and provides 32 channels, with selectable input polarity, and three possible combinations of shaping time and sensiti
This study compares the performance of simulated shallow ponds vegetated with Lemna minor L. under controlled and semi-natural conditions for the treatment of simulated wastewater containing textile dyes. The objectives were to assess the water quality outflow parameters, the potential of L. minor concerning the removal of chemical oxygen demand (COD) and four azo dyes (Acid blue 113, reactive blu
The decrease of Ortolan Bunting Emberiza hortulana inWestern Europe over the last five decades has caused seriousconcern for the survival of this species in Sweden.In order to find out the migration routes and wintering location,we equipped several males with geologgers. Ourdata show annual cycles of migrations routes, winteringgrounds and time schedules for seven re-trapped birds.The wintering ar
The 2-oxoglutarate dehydrogenase multienzyme complex is composed of three different subenzymes: 2-oxoglutarate dehydrogenase (E1o), dihydrolipoamide transsuccinylase (E2o), and dihydrolipoamide dehydrogenase (E3). Bacillus subtilis E1o and E2o are encoded by the citK and citM genes, respectively. A 3.4-kb BamHI DNA fragment containing citK and citM markers was isolated from a library of B. subtili
Background: The aim of this paper was to review the literature on vacuum-Assisted wound closure and mesh-mediated fascial traction (VAWCM) in open abdomen therapy. It was designed as systematic review of observational studies. Methods: A Pub Med, EMBASE and Cochrane search from 2007/01-2016/07 was performed combining the Medical Subject Headings "vacuum", "mesh-mediated fascial traction", "tempora
Background: Nonsteroidal anti-inflammatory drugs (NSAIDs) have been widely used in colorectal surgery due to their opioid-sparing effect. However, several studies have indicated an increased risk of anastomotic leakage following NSAID treatment, although conflicting results exist. The primary goal of this study was to further examine whether postoperative NSAIDs are independently associated with a
The diagnostic steps for primary aldosteronism (PA) include case screening tests, confirmatory tests, and localization. The aim of this study was to identify useful confirmatory tests and their cut-off values for differentiating the subtype of primary aldosteronism, especially in unilateral PA, such as aldosterone-producing adenoma, and bilateral PA, such as idiopathic hyperaldosteronism. Seventy-
The possible importance of virus infections before the development of islet autoimmunity and then for the appearance of clinical type 1 diabetes is reviewed. There is a lack of specific data on the role of virus to induce islet autoimmunity. There is also a paucity of data to demonstrate that virus infections may contribute to an accelerated disease process resulting in clinical onset of type 1 di
Electric Hybrid Vehicles (EHVs) play a crucial role in the development towardsa more environmental friendly transportation. An alternative to solve someactual challenges with hybridization of vehicles is studied at the Division ofIndustrial Electrical Engineering and Automation (IEA) at Lund Universityin cooperation with the automotive industry. A key component of this drivetrain is a highly dynam
Fabless production, meaning manufacturing without owning fabrication facilities, has been suggested as a novelty by the semiconductor industry. However, Ikea, the global furniture company based in Sweden, has successfully been producing their furniture in a fabless fashion since 1955. This paper explores how Ikea manage and control its almost fabless production to reach the company’s targets for s
In T lymphocytes, lipid rafts are preferred sites for signal transduction initiation and amplification. Many cell membrane receptors, such as the TCR, coreceptors, and accessory molecules associate within these microdomains upon cell activation. However, it is still unclear in most cases whether these receptors interact with rafts through lipid-based amino acid modifications or whether raft insert
