English vocabulary learning through watching YouTube videos and reading blog posts

Research on the Online Informal Learning of English has found that social media can facilitate language learning, mainly in the domain of vocabulary. It does so not only by providing the necessary language input, but also through the unique ways in which social media platforms encourage interaction between the user and the content as well as with other users. The present study investigated English

Evaluation of Platelet Responses in Transfusion-Related Acute Lung Injury (TRALI)

Platelets are versatile cells which are capable of eliciting nonhemostatic immune functions, especially under inflammatory conditions. Depending on the specific setting, platelets may be either protective or pathogenic in acute lung injury and acute respiratory distress syndrome (ARDS). Their role in transfusion-related acute lung injury (TRALI) is less well defined; however, it has been hypothesi

Applications of the google earth engine and phenology-based threshold classification method for mapping forest cover and carbon stock changes in Siem Reap province, Cambodia

Digital and scalable technologies are increasingly important for rapid and large-scale assessment and monitoring of land cover change. Until recently, little research has existed on how these technologies can be specifically applied to the monitoring of Reducing Emissions from Deforestation and Forest Degradation (REDD+) activities. Using the Google Earth Engine (GEE) cloud computing platform, we

Situated Counting

We present a model of how counting is learned based on the ability to perform a series of specific steps. The steps require conceptual knowledge of three components: numerosity as a property of collections; numerals; and one-to-one mappings between numerals and collections. We argue that establishing one-to-one mappings is the central feature of counting. In the literature, the so-called cardinali

Nanowire devices for X-ray detection

High spatial resolution X-ray microscopy has become a dedicated tool to study nanocrystals and nanostructure devices in recent years. In general, the spatial resolution of X-ray microscopy depends on the spot size of the X-ray beam and the pixel size of X-ray detectors. High-resolution X-ray detection ideally requires a minimal active region with a sufficient thickness for the X-ray absorption, wh

Penile intraepithelial neoplasia, penile cancer precursors and human papillomavirus prevalence in symptomatic preputium : a cross-sectional study of 351 circumcised men in Sweden

Objectives: To investigate the prevalence of pathological disease and spectrum of human papillomavirus (HPV) types among symptomatic foreskin tissue. Patients and Methods: Consecutively excised symptomatic foreskins from 351 men were sent for histopathological evaluation. During the surgical procedure, a fresh biopsy was taken for HPV analysis by modified general primer polymerase chain reaction.

NaCl pellets for prospective dosimetry using optically stimulated luminescence : Signal integrity and long-term versus short-term exposure

Optically stimulated luminescence (OSL) signal properties of pellets from three types of NaCl (two household salts and one analytical grade salt) were investigated for their use in prospective dosimetry. Special attention was given to the OSL signal behaviour with time. The readout protocol was optimised in terms of preheat temperature, and the OSL signal yield of the NaCl pellet with time as well

Guiding the student entrepreneur – Considering the emergent adult within the pedagogy–andragogy continuum in entrepreneurship education

Purpose: The purpose of the paper is to build on current discussions about the need for and role of guidance in learning and teaching, as well as to theoretically develop its specifics to further advance our scholarly understanding of how to structure and enhance entrepreneurship education. Design/methodology/approach: The paper takes a synthesizing conceptual approach, built on developmental psyc

På väg mot en förståelse av fenomenet inkongruent predikativ : Ett försök att beskriva och förklara fenomenet samt skildra dess forskningshistoria

This thesis examines so-called pancake sentences, an agreement anomaly found in Swedish, Danish and Norwegian. In these languages, predicative adjectives typically agree with their subjects in number and grammatical gender. However, with certain subjects the predicative takes a t-form, corresponding to singular neuter, regardless of the number and gender of the subject. Such sentences are commonlyThis thesis examines so-called pancake sentences, an agreement anomaly found in Swedish, Danish and Norwegian. In these languages, predicative adjectives typically agree with their subjects in number and grammatical gender.

Serology assessment of antibody response to SARS-CoV-2 in patients with COVID-19 by rapid IgM/IgG antibody test

The coronavirus disease 2019 (COVID-19) pandemic has created a global health- and economic crisis. Detection of antibodies to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which causes COVID-19 by serological methods is important to diagnose a current or resolved infection. In this study, we applied a rapid COVID-19 IgM/IgG antibody test and performed serology assessment of antibody

Do markets encourage risk-seeking behaviour?

Excessive risk-taking in markets can have devastating consequences as the latest financial crises have highlighted. In this paper, we ask whether markets as an institution encourages such excessive risk-taking. To establish causality, we isolate the effects of market interaction in a laboratory experiment keeping other possibly confounding factors constant. We find that the opposite is true. Marke

Outcome of carpal tunnel release in patients with normal nerve conduction studies

Background: We evaluated outcome after carpal tunnel release (CTR) in patients with clinically diagnosed carpal tunnel syndrome (CTS) but normal results in nerve conduction studies (NCS), and compared these results with those from a prospective group of patients with NCS-verified CTS. Methods: Over a 5-year period, we prospectively included 103 patients with clinical CTS. NCS were done at inclusio

The effects of variable, intermittent, and continuous negative pressure wound therapy, using foam or gauze, on wound contraction, granulation tissue formation, and ingrowth into the wound filler

OBJECTIVE: Negative pressure wound therapy (NPWT) is commonly used in the continuous mode. Intermittent pressure therapy (IPT) results in faster wound healing, but it often causes pain. Variable pressure therapy (VPT) has therefore been introduced to provide a smooth transition between 2 different pressure environments, thereby maintaining the negative pressure environment throughout the therapy.

Costs of diabetes complications : hospital-based care and absence from work for 392,200 people with type 2 diabetes and matched control participants in Sweden

Aims/hypothesis: The risk of complications and medical consequences of type 2 diabetes are well known. Hospital costs have been identified as a key driver of total costs in studies of the economic burden of type 2 diabetes. Less evidence has been generated on the impact of individual diabetic complications on the overall societal burden. The objective of this study was to analyse costs of hospital

Patient-reported outcomes of joint-preserving surgery for moderate hallux rigidus : a 1-year follow-up of 296 patients from Swefoot

Background and purpose — Hallux rigidus (HR) may cause decreased range of motion, joint pain, and gait disturbances. There is a lack of evidence regarding the outcome of different surgical procedures for moderate HR. We report patient-reported outcomes after joint-preserving surgical procedures for moderate HR. Patients and methods — We included 296 patients registered in Swefoot (Swedish national

Genome-wide association study identifies novel single nucleotide polymorphisms having age-specific effect on prostate-specific antigen levels

Background: Testing for prostate-specific antigen (PSA) levels in blood are widely used and associated with prostate cancer risk and outcome. After puberty, PSA levels increase by age and multiple single nucleotide polymorphisms (SNPs) have been found to be associated with PSA levels. However, the relationship between the effects of SNPs and age on PSA remains unknown. Methods: To test for SNP × a

Computing and visualising intra-voxel orientation-specific relaxation–diffusion features in the human brain

Diffusion MRI techniques are used widely to study the characteristics of the human brain connectome in vivo. However, to resolve and characterise white matter (WM) fibres in heterogeneous MRI voxels remains a challenging problem typically approached with signal models that rely on prior information and constraints. We have recently introduced a 5D relaxation–diffusion correlation framework wherein

Vascular dimorphism ensured by regulated proteoglycan dynamics favors rapid umbilical artery closure at birth

The umbilical artery lumen closes rapidly at birth, preventing neonatal blood loss, whereas the umbilical vein remains patent longer. Here, analysis of umbilical cords from humans and other mammals identified differential arterial-venous proteoglycan dynamics as a determinant of these contrasting vascular responses. The umbilical artery, but not the vein, has an inner layer enriched in the hydrate

Improvements of the adiabatic film cooling by using two-Row holes of different geometries and arrangements

Existing researches on two-row film cooling mainly focused on double-jet film cooling. However, researches on the effects by combining different kinds of hole shapes on film cooling performance are quite limited. In order to improve the film cooling effectiveness, the three-dimensional numerical method is utilized to investigate the effects of a novel structure composed of two-row holes with diffe

PET amyloid in normal aging : direct comparison of visual and automatic processing methods

Assessment of amyloid deposits is a critical step for the identification of Alzheimer disease (AD) signature in asymptomatic elders. Whether the different amyloid processing methods impacts on the quality of clinico-radiological correlations is still unclear. We directly compared in 155 elderly controls with extensive neuropsychological testing at baseline and 4.5 years follow-up three approaches:
