The recent surge of scientific interest for lead halide perovskite semiconductors and optoelectronic devices has seen a mix of materials science sub-fields converge on the same "magical" crystal structure. However, this has ultimately shaped some ambiguity in the definitions shared between researchers across different research areas. For example, scientists aiming to decipher the nature of localiz
In this conceptual paper theory of infrastructure is combined with one of situated learning, with a focus on search and search engines. The aim of the paper is to make a theoretical contribution to the information literacy research field by discussing theoretical contradictions as well as strengths when combining the two theoretical perspectives. Search engines and their use are part of the contem
Introduction: Colorectal cancer (CRC) is one of the leading causes of cancer-related deaths worldwide. Cyclooxygenase-2 (COX-2), which plays a key role in the biosynthesis of prostaglandin E2 (PGE2), is often up-regulated in CRC and in other types of cancer. PGE2 induces angiogenesis and tumor cell survival, proliferation and migration. The tumor suppressor 15-hydroxyprostaglandin dehydrogenase (1
Objective: To assess how the prevalence of pain in a population-based sample of children and adolescents with cerebral palsy (CP) differ based on self- or proxy reporting. Methods: This cross-sectional registry study included 3783 children (58% boys), 1 to 18 years old, enrolled in the Swedish follow-up program for CP. Logistic regression was used to regress source of reporting (self or proxy) on
This study examined the longitudinal associations between non-suicidal self-injury (NSSI) in early adolescence and various positive and negative aspects of mental health in young adulthood. The participants were a cohort of regular school students (n = 1064) in grades 7–8 from a Swedish municipality. Nine hundred and ninety-one of these completed an 11-page questionnaire (T1: Mage = 13.7; 50.3% gi
Decrease of saline lakes, which comprise 44% of all available lake water, is a major concern. It additionally accelerates the desertification process of the region. Thus, various countries have taken different actions in protecting their lake water levels. The aim of this paper is to assess different strategies directed to tackle the decreased lake water levels in Lake Urmia and the Aral Sea, whic
Epidermolysis bullosa simplex (EBS) is usually inherited as an autosomal dominant disease due to monoallelic gain-of-function mutations in KRT5 or KRT14. Although autosomal recessive forms of EBS have been associated with mutations in at least 10 genes, recessive EBS due to homozygous biallelic KRT5 mutations has not been reported previously; it has been hypothesized that it would result in prenat
Genetic factors are often overlooked in conservation planning, despite their importance in small isolated populations. We used mitochondrial and microsatellite markers to investigate population genetics of the adder (Vipera berus) in southern Britain, where numbers are declining. We found no evidence for loss of heterozygosity in any of the populations studied. Genetic diversity was comparable acr
Background: Diet is a determinant of gut microbiota. Both diet and gut microbiota have been linked to metabolic diseases. Objective: We aimed to examine data-driven food patterns in relation to the prevalence of prediabetes and gut microbiota composition and food pattern-associated bacteria in relation to prediabetes. Methods: Food patterns were extracted using principal component analysis in 1726
Abstract. In addition to the pheromone components (Z)‐5‐decenyl, (Z)‐7‐dodecenyl and (Z)‐9‐tetradecenyl acetate (Z5‐10:OAc, Z7‐12:OAc and Z9‐14:OAc), it has previously been shown that the sex pheromone gland of the turnip moth, Agrotis segetum (Lepidoptera: Noctuidae Schiff) contains 10:OAc, 12:OAc, Z5‐12:OAc, Z9‐12:OAc, 11–12:OAc, Z5‐14:OAc, Z7‐14:OAc and Z11‐16:OAc. To find out whether any of t
This chapter uses the term adaption in the sense of how a regionally based, popular culture phenomenon has nurtured structural economic transformation. The chapter elaborates a critical examination of the comparative popularity of Nordic noir, asking whether the two long-running film and television crime franchises Wallander (Wallander, (1994–2016) and The Bridge (Bron/Broen, 2011–2018) have been
Chills and vomiting have traditionally been associated with severe bacterial infections and bacteremia. However, few modern studies have in a prospective way evaluated the association of these signs with bacteremia, which is the aim of this prospective, multicenter study. Patients presenting to the emergency department with at least one affected vital sign (increased respiratory rate, increased he
This article presents practice-theoretical conceptions of societal relations to nature as a fruitful alternative to common system approaches in social-ecological research. Via the example of plastic food packaging, two different practice-theoretical approaches to food supply are discussed regarding their suitability for relating the material properties of packaging to their everyday use by produce
The design of the stator insulation system for a traction machine used in electric vehicles is a challenge due to the tight requirements set on compact size, high dynamic stresses and a lack of automotive specific insulation standards. A poorly designed stator insulation can lead to safety issues and stator faults. Approximately, 20-30% of faults in traction machines are stator faults. In order to
BACKGROUND: It is discussed whether fetal scalp stimulation (FSS) test is a reliable complimentary tool to cardiotocography (CTG) to assess fetal wellbeing during labor. The test is based on the assumption that a well-oxygenated fetus, in contrast to the depressed fetus, will respond to a certain stimulus. The aim of this study was to investigate the effectiveness of the FSS-test.METHODS: A retros
Objectives: The aim of this feasibility study was to evaluate the added value of contrast-enhanced mammography (CEM) in preoperative staging of malignant breast lesions, beyond standard assessment with digital mammography and ultrasound, as a base for a future prospective randomized trial. Materials and methods: Forty-seven patients, with confirmed or strongly suspected malignant breast lesions af
OBJECTIVE: To assess pulmonary function and Chronic Obstructive Pulmonary Disease (COPD) development over time in patients with primary Sjögren's Syndrome (pSS) and the association between pulmonary function, radiographic findings, respiratory symptoms and clinical features of pSS, taking cigarette consumption into account.METHODS: Forty patients with pSS (mean age 66 yrs, range 42-81 yrs, 39 wome
Do Chinese cities compete for investments with lax environmental law enforcement? The here presented study suggests that this is true for some municipalities but not all of them. Based on data for 126 key environmental protection cities and regional economic hubs between 2010 and 2012 we show that economic decentralization and political centralization both shape spatial patterns of compliance with
