Limits are set on the pair production of scalar leptoquarks, where all possible decays of the leptoquark into a quark (t, b) and a lepton (τ, ν) of the third generation are considered. The limits are presented as a function of the leptoquark mass and the branching ratio into charged leptons for up-type (LQ3 u → tν/bτ) and down-type (LQ3 d → bν/tτ) leptoquarks. Many results are reinterpretations of
Contact stress on the tool has been measured with a split-tool apparatus that has a poor resolution of the stress distribution, and with photoelastic tools that cannot be used with real cutting parameters since the materials are too weak. This paper presents an improved split-tool design allowing continuous stress distribution dataset instead of discreet steps by using a tilted separation plane be
The application of one-dimensional nanofibers in the fabrication of an electrode greatly improves the performance of solid oxide fuel cells (SOFCs) due to its advantages on electron transfer and mass transport. Various mixed ionic-electronic conducting materials with perovskites and Ruddlesden-Popper-type metal oxide structures are successfully electrospun into nanofibers in recent years mostly in
The Swedish steel industry stands before a potential transition to drastically lower its CO2 emissions using direct hydrogen reduction instead of continuing with coke-based blast furnaces. Previous studies have identified hydrogen direct reduction as a promising option. We build upon earlier efforts by performing a technological innovation system study to systematically examine the barriers to a t
Purpose: The purpose of this study was to investigate what treatment methods physiotherapists in Sweden use for infants 0–24 months hospitalised with acute breathing difficulties due to lower respiratory tract infections. Material and methods: We constructed an anonymous digital survey for paediatric physiotherapists in Sweden. It was distributed by e-mail and was posted on professional websites.
Analyzing the fluid behavior in complex porous media like gas diffusion layers (GDLs) in polymer electrolyte fuel cells (PEFCs) can be accurately done using the lattice Boltzmann method (LBM). This article shows the data obtained from a study in which diffusion parameters such as porosity, gas phase tortuosity and diffusibility are computed considering simulated porous media [1]. The data were com
The experimental methodology achieved in the present study signified that the adsorption and precipitation were main mechanisms occurred together in the removal of nickel from aqueous solution by sorption using cement kiln dust (CKD) byproduct as sorbent. Finding the contribution of each mechanism in the removal process and derivation an analytical model for finding the portion of precipitation we
Use of image-guided radiation therapy (IGRT) helps to account for daily prostate position changes during radiation therapy for prostate cancer. However, guidelines for the use of IGRT are scarce. An ESTRO panel consisting of leading radiation oncologists and medical physicists was assembled to review the literature and formulate a consensus guideline of methods and procedure for IGRT in prostate c
The exact mechanism of action of IVIg in the amelioration of immune thrombocytopenic purpura (ITP) is still unclear. Studies have suggested that IVIg may function through the regulation of cytokines, including interleukin-1 receptor antagonist (IL-1Ra), an inhibitor of phagocytosis. Using a mouse model relevant to ITP, we confirm an increase in mouse serum levels of IL-1Ra after exposure to IVIg,
Background. In general practice, dysfunctions within the locomotor system are a recurring health issue. Most frequently, diagnoses and treatments relate to pain syndromes of the backbone, the shoulder girdle or the pelvic girdle. The authors believe that physiotherapy, along with other clinical disciplines, should be regarded as an important factor which influences the effectiveness of the therape
Background: Genetic factors are important in determining breast density, and heritable factors account for 60% of the variation. Certain single nucleotide polymorphisms (SNPs) are associated with density and risk of breast cancer but the association with prognosis is not clear. Purpose: To investigate associations between selected SNPs and breast cancer survival in the Malmö Diet and Cancer Study
Thousands of barley (Hordeum vulgare L.) mutants have been isolated over the last century, and many are stored in gene banks across various countries. In the present work, we developed a pipeline to efficiently identify causal mutations in barley. The pipeline is also efficient for mutations located in centromeric regions. Through bulked segregant analyses using whole genome sequencing of pooled F
AIMS: The aim of this study was to identify and describe methods that physiotherapists use to evaluate the immediate effects of their interventions for infants in hospital with acute respiratory tract infections.METHODS: We constructed an anonymous digital survey to physiotherapists working with infants aged 0-24 months in Sweden. The survey was distributed by e-mail and posted on web pages for se
This paper forms part of a broader study on the design optimization of a high speed switched reluctance motor for automotive traction applications. Due to the high speed operation and resulting high electrical frequency, it is of extreme importance that the different loss components of this motor are accurately calculated. In this study, several effects are observed that influence the accurate mea
We have employed a new approach to quantify the amount fraction of nitrous oxide in a synthetic air matrix gas used to prepare high-accuracy reference materials of the same component. Until now, this was the largest contributor to the measurement uncertainty of nitrous oxide in air reference materials at atmospheric amount fractions (∼330 nmol mol-1), as identified in a recent international compar
Statistics reveal the concerning prevalence of mental health issues among Swedish public sector managers, highlighting the critical need for deeper insights into the relevance of social support in coping with work-related stress. This study aims to examine the relevance of various sources of social support for managers coping with work-related stress, an area relatively underexplored in public adm
In this study, we present the initial results from a long-term initiative to develop a multi-millennial tree-ring width (TRW) chronology for subfossil oak (Quercus spp.) trees in South Scandinavia. We have constructed 40 TRW chronologies, primarily from oak trunks extracted from peatlands, archaeological sites, drainage ditches, and infrastructure projects, as well as some submerged material. The
This study employs computational algorithms to automatically identify and classify features in X-Ray fluorescence (XRF) microscopy images. Principal component analysis (PCA) and unsupervised machine learning algorithms, such as Gaussian mixture (GM) clustering, are implemented to label features on a collection of XRF maps of human atherosclerotic plaque samples. The investigation involves the hard
