The operational management of offshore wind farms includes inspection and maintenance (I&M) of the wind turbine support structures. These activities are complex and influenced by numerous uncertain factors that affect their costs. The uncertainty in the I&M costs should be considered in decision value analyses performed to optimize I&M strategies for the turbine support structures. In

An experimentally based prediction model of road abrasion wear due to studded tyres is available in Sweden and has been found to work well. However, it has not been validated since 2007, and since then road surfaces and tyre design have developed, and the question has arisen regarding the model’s current validity. The abrasion wear model is used in the NORTRIP emission model (NOn-exhaust Road Traf

Due to advances in technology, sampling procedures and short lag times between successive sampling, autocorrelation among the measured data has become common in most applications. Neglecting autocorrelation leads to a poor false alarm performance. In the current paper, the effect of the autocorrelation on the performance of a variable-parameters multivariate single control chart is investigated in

Variable parameters (VP) schemes are the most effective adaptive schemes in increasing control charts' sensitivity to detect small to moderate shift sizes. In this paper, we develop four VP adaptive memory-type control charts to monitor multivariate multiple linear regression profiles. All the proposed control charts are single-chart (single-statistic) control charts, two use a Max operator and tw

Objective: This retrospective, multicentre, observational study analysed patients who underwent endovascular repair for blunt traumatic aortic injury (BTAI) at four tertiary trauma referral centres over twenty years. It aimed to determine early and long term survival, to analyse aortic and device related complications, and to assess the re-intervention rate after endovascular repair for BTAI. Meth

This article focuses on teachers’ and principals’ experiences of aggressive emails in home–school collaborations with parents. Semi-structured interviews with 31 teachers and principals from primary, lower and upper secondary schools in Sweden were conducted. Three categories were identified in the material which illuminate the phenomenon of cyberaggression towards principals and teachers from par

In the plant-based beverage industry, a residue called okara, is generated in large quantities in the liquid-solid separation step. Despite the high nutritional value of okara from soy and oat beverages with respect to fiber and protein content, these residues are generally discarded or used as animal feed or compost. It would be more sustainable to utilize okara for human consumption, however, th

BACKGROUND: Recent advances now allow detection of brain-specific proteins in blood, including neurofilament light chain (NfL), a marker of axonal pathology, and glial fibrillary acidic protein (GFAP), indicative of astrocytic activation. Given the evidence of astroglial pathology and neuronal dysfunction in bipolar disorder, and ongoing debates on neuroprogression, we investigated plasma NfL and

Background: The existence of a “minority tax,” defined as the burden of extra responsibilities placed on minorities relative to non-minorities of the same position, has been documented across various fields, including and beyond medicine. This study sought to quantify the types and extent of the minority tax faced by minority orthopaedic surgeons, as well as evaluate the degree to which this work

PurposeThe purpose is to increase the understanding of when a heritage in the non-profit category becomes a part of the established heritage sector, and how this can be understood with regard to the rising awareness of climate change in heritage management and recent theories within the field. The case is Hindås Ski Jumping Hill in Hindås, Sweden, which since 2022 is a listed building in Sweden.De

This study analyzes the transition to mechanized forest management and the implementation of sustainable-yields forestry in Sweden during the 1950s and 1960s. The objective is to produce insights that are relevantfor policymakers working with forests and the climate transition today. The analysis focuses on how the Swedish National Association of Forest Owners’ Associations (SSR)—an association or

Taboo obsessions are ego-dystonic, recurrent, and intrusive thoughts involving aggressive, sexual and/or religious themes, which are common in individuals with obsessive-compulsive disorder (OCD). These symptoms are often challenging to treat with traditional, exposure-based approaches. Our research group has developed and successfully piloted an Internet-delivered intervention based on the cognit

A series of Na0.67Ni0.33Mn0.67-xSnxO2 (x = 0, 0.01, 0.03, 0.05) materials with mixed P2/P3 phases are synthesized with a conventional solid-state reaction method and investigated as cathode materials for sodium ion batteries. The effects of Sn substitution on the structure and electrochemical performance of the Na0.67Ni0.33Mn0.67O2 are systematically investigated. The substituted samples show smal

Nocturia, the urge to wake from sleep to void, is targeted sub-optimally by existing drugs that modulate circadian dysregulation of urine production in kidney without alleviating detrusor overactivity, a key aspect in the multifactorial etiology of nocturia. This study reports age-related upregulation of arginine vasopressin (AVP) synthesis in mouse urinary bladder to counter the concurrent declin

Objective: Evaluate the impact of adrenalectomy on metabolic parameters and quality of life (QoL) in patients with mild autonomous cortisol secretion (MACS). Method: A multicenter prospective randomized clinical trial compared adrenalectomy with conservative management. Metabolic parameters and QoL were assessed at baseline and after 2 years. Results: Forty-three MACS patients with a single adrena

Objective: Ampullary neoplastic lesions can be resected by endoscopic papillectomy (EP) or transduodenal surgical ampullectomy (TSA) while pancreaticoduodenectomy is reserved for more advanced lesions. We present the largest retrospective comparative study analysing EP and TSA. Design: Of all patients in the database, lesions with prior interventions, benign histology advanced malignancy (T2 and m

Background: Parkinson's disease is a progressive neurodegenerative disorder. Awareness and the evidence supporting the merits of palliative care (PC) approaches to people with Parkinson's disease (PwP) are increasing. Objective: This review aimed to address four key questions related to PC for PwPs and their caregivers: i) What are the indicators for timely access to PC? ii) When should PC be intr
