Purpose: While big data creates business value, knowledge on how value is created remains limited and research is needed to discover big data’s value mechanism. The purpose of this paper is to explore value creation capabilities of big data through an alignment perspective. Design/methodology/approach: The paper is based on a single case study of a service division of a large Danish wind turbine g
Purpose: The purpose of this study is to investigate the effects of film holes’ arrangements and jet Reynolds number on flow structure and heat transfer characteristics of jet impingement conjugated with film cooling in a semicylinder double wall channel. Design/methodology/approach: Numerical simulations are used in this research. Streamlines on different sections, skin-friction lines, velocity,
Wildlife conservation policies directed at common and widespread, but declining, species are difficult to design and implement effectively, as multiple environmental changes are likely to contribute to population declines. Conservation actions ultimately aim to influence demographic rates, but targeting actions towards feasible improvements in these is challenging in widespread species with ranges
Purpose: This study aims to explore the 3 D separated flow fields and heat transfer characteristics at the end wall of a serpentine channel with various turn clearances using topological analysis and critical points principles of three-dimensional vortex flow. Design/methodology/approach: This aims to explore the 3 D separated flow fields and heat transfer characteristics at the end wall of a serp
Objectives: A measurement tool to assess systematic reviews 2 (AMSTAR 2) was originally developed for systematic reviews (SRs) of health-care interventions. The aim of this study was to assess the applicability of AMSTAR 2 to SRs of non-intervention studies. Study design and setting: This was a meta-research study. We used 20 SRs for each of the following four types of SRs: Diagnostic Test Accurac
Complex metabolic diseases due to overnutrition such as obesity, type 2 diabetes, and fatty liver disease are a major burden on the healthcare system worldwide. Current research primarily focuses on disease endpoints and trying to understand underlying mechanisms at relatively late stages of the diseases, when irreversible damage is already done. However, complex interactions between physiological
Objectives. The aim was to demonstrate a reliable ex vivo method to test the function of the whole heart. Design. Pigs of varying sizes (44–80 kg) were exposed to dose response of adrenaline. Blood pressures and cardiac output were measured. The explanted hearts were tested in a novel ex vivo system to see if we could replicate the in vivo values at maximal adrenaline stimulation. The perfusion so
Centrifugal compressors are widely used in turbocharged powertrains for Heavy-Duty applications. The volute of the centrifugal compressors is generally of the overhung type. The design of volutes is often neglected, and the shape of the volute is dictated by the packaging requirements of the engine. However, with the advent of Hydrogen-based propulsion systems, the efficiency of all the components
Recent Advances: Various studies have suggested that mitochondrial DNA copy number (mtDNA-CN), a surrogate biomarker of mitochondrial dysfunction, is an easily quantifiable biomarker for chronic diseases, including diabetes and cancer. However, current knowledge is limited, and the results are controversial. This has been attributed mainly to methodology and study design.Critical Issues: The incid
The most important moment in product development is when demands and specifications are decided for the product that is being planned. The specification defines the goal for the product development process. It is a very important steering opportunity for the continuing work and for environmentally driven demands that are to be addressed in the product development phase. The designers are said to h
Peripheral artery disease affects >200 million people worldwide and is associated with significant limb and cardiovascular morbidity and mortality. Limb revascularization is recommended to improve function and quality of life for symptomatic patients with peripheral artery disease with intermittent claudication who have not responded to medical treatment. For patients with critical limb ischemia,
Media, technology and globalization are the key words in academic contemporary consumer and cultural research going on today. From these ideas, many different research directions could diverge. This thesis explores the listening habits of female, native Finnish and English speakers living in Sweden who are within the age groups of 20’s to 40’s. Focusing on media, technology, and mobile world citiz
Previous research on A/B testing and continuous experimentation has mostly focused on large-scale settings with company-external customers. However, work efficiency and satisfaction for company coworkers may be highly related to internal tools and their fit-for-use. In this study, we therefore explore A/B testing for online services exclusively used by company co-workers. We A/B tested two version
Purpose – Competence development is a prerequisite for successfully meeting existing and future challenges in the retail sector. However, current human resource development practices are often limited in their scope and offerings. This study sets out to investigate and bring to light informal learning among retail professionals.Design/methodology/approach – This research consists of two explorator
Natural flood management is emerging as a viable way to leverage ecological services to manage flooding. Stakeholders are progressively positioning natural flood management at the scale of river catchments to encourage a move beyond localised and opportunistic actions towards more strategic and cost-effective flood risk management responses. This reflects a broader turn towards nature-based soluti
OBJECTIVE: The longitudinal variations in serum levels of the hormone osteocalcin is largely unknown during infancy and early childhood. Our aim was to establish reference limits for total serum osteocalcin during specific time points from birth until 5 years of age and present those in the context of sex, breastfeeding practices and gestational age (GA).DESIGN: Blood samples from 551 Swedish chil
Deep ice cores from polar ice sheets enable reconstructions of Earth’s past climate. Ice core records are therefore crucial for projecting future climate change, but our ability to interpret them relies on our understanding of polycrystalline-ice microstructures and mechanics. In turn, these microstructures enable modeling of ice flow and large-scale effects of ice sheet evolution. Since drilling
Background: Atherosclerotic cardiovascular disease is a chronic inflammatory process initiated when cholesterol-carrying low-density lipoprotein (LDL) is retained in the arterial wall. CD4+ T cells, some of which recognize peptide components of LDL as antigen, are recruited to the forming lesion, resulting in T-cell activation. Although these T cells are thought to be proatherogenic, LDL immunizat
Purpose The aim of the research was to investigate how a model for public procurement could be designed with the aim of including industrially produced housing in the procurement process in Sweden. Methodological approach The study was performed in two steps, an initial literature review and then a case study. The literature review aimed at creating an understanding of how this is done in other c
