There is a large interest in predicting high-pressure homogenizer (HPH) valve hydrodynamics using CFD, in academic research and industrial R&D. Most of these studies still use two-equation RANS turbulence models, whereas only a few have used LES formulations. From a theoretical perspective, LES is known to be more accurate than RANS, especially in terms of estimating the dissipation rate of tuThere is a large interest in predicting high-pressure homogenizer (HPH) valve hydrodynamics using CFD, in academic research and industrial R&D.

BACKGROUND: Kinetic energy (KE) of intracardiac blood flow reflects myocardial work spent on accelerating blood and provides a mechanistic window into diastolic filling dynamics. Diastolic dysfunction may represent an early stage in the development of heart failure (HF). Here we evaluated the hemodynamic effects of impaired diastolic function in subjects with and without HF, testing the hypothesis

The twenty-frst century has seen the concurrent rise of optimism about economic growth in sub-Saharan Africa and the return of the agricultural sector to the top of the development agenda. Ethiopia—with its rapid economic growth for two decades, achieved during a policy focus on the agricultural sector—is at the forefront of both these developments. This chapter introduces the book’s main theme of

Recent droughts from 2017 to 2020 induced significant stress on woodland canopies across eastern Australia, resulting in widespread tree browning and mortality. However, the trajectory of post-drought recovery remains unclear, with uncertainty about whether canopy conditions are improving or continuing to decline. Identifying the key local environmental and climatic factors influencing drought-ind

Background: Subgroups of adult-onset diabetes, namely severe autoimmune diabetes (SAID), severe insulin-deficient diabetes (SIDD), severe insulin-resistant diabetes (SIRD), and mild obesity-related diabetes (MOD) or mild age-related (MARD) diabetes, have been defined with clinical variables and a machine-learning approach. Our aim was to describe their long-term outcomes and mortality. Methods: In

Sensory traits shape animal lifestyles due to the central role they play in retrieving and processing environmental information. However, being some of the most energetically expensive tissues to build and maintain, ecological demands often modulate investment in these organs. Evidence that ecology shapes the evolution of sensory traits is plenty but is heavily biased towards vertebrates and has o

Carbon sequestration in arable soils is gaining increasing attention in global policymaking initiatives for climate-change mitigation. Large-scale assessments of soil organic carbon development in arable land are affected by the scarcity of reliable time series of soil organic carbon monitoring data and often fail to replicate observed trends or appreciate any effects induced by changes in soil ma

Streptococcus pyogenes causes a multitude of local and systemic infections, the most common being pharyngitis in children. Recurrent pharyngeal infections are common and are thought to be due to the re-emergence of intracellular GAS upon completion of antibiotic treatment. The role of colonizing biofilm bacteria in this process is not fully clear. Here, live respiratory epithelial cells were ino

With the introduction of information theory in the middle of the 20th century, the concept of noise came to be contrasted with signal. The exhibition Noise to Signal mainly consists of two projects that highlight the relative nature of these terms.The three textile works, all with the title Untitled (Noise), appear abstract but also represent a grainy filter that is usually applied to digital imag

During the Late Iron Age, a large variety of dogs and the earliest evidence of dog leashes appear in Scandinavia. This study is based on an analysis of the dogs in the Nabberör boat grave on the island of Öland in relation to dogs from other burials and settlements.Breeding and care of the dogs have been analysed through the integrated life stories of individual dogs, based on age, sex and health

The production, reading and correcting of article proofs is a highly important part of scholarly publishing, and the proof of an article is the only place where researcher, journal production team and publisher come together, directly or indirectly.

To investigate whether coronary artery disease (CAD) burden is associated with plasma levels of the myocardial biomarkers Troponin I (TropI) and NT-proBNP in a large population-based sample using a cross-sectional design. Coronary computerized tomography (CT) angiography was performed in 25,859 subjects without a history of atherosclerotic disease from SCAPIS study (age 50-65, 52% women). TropI an

Sustainable Aviation Fuels (SAF) typically exhibit a composition that differs significantly from conventional jet fuels. These variations in chemical makeup influence the thermophysical and reactive properties of these propellants. In this study, Finite-Rate Chemistry (FRC) Large Eddy Simulations (LES) are employed to investigate turbulent spray flames from a Triple Annular Research Swirler (TARS)

Background: P-wave indices reflect atrial abnormalities contributing to atrial fibrillation (AF). We aimed to assess a comprehensive set of P-wave characteristics for prediction of incident AF in a population-based setting. Methods: Malmö Preventative Project (MPP) participants were reexamined in 2002–2006 with electrocardiographic (ECG) and echocardiographic examinations and followed for 5 years.

Two studies were performed in this paper. The first study was a method development examining the possibilities to do a serial extraction of lipids, PCB 153, NSAIDs (non-steroidal anti-inflammatory drugs) and selective serotonin reuptake inhibitors (SSRIs) from a single sample. Five different treatments were tested with three replicates from each individual fish. All samples were first freeze-dried
