BACKGROUND: The study aimed to describe all diagnosed cases of Legionnaire's disease (LD) in south Sweden, regarding incidence, patient characteristics, diagnostics, outcomes, and infection control investigations.METHODS: This population-based retrospective study was conducted in Skåne, on patients with LD between 2011-2021. Inclusion criteria were positive polymerase chain reaction (PCR) for L.
We propose a dynamical model depicting nitrogen (N2) fixation (diazotrophy) in a unicellular cyanobacterium, Crocosphaera watsonii, grown under light limitation and obligate diazotrophy. In this model, intracellular carbon and nitrogen are both divided into a structual pool and a storage pool. An internal pool that explicitly describes the nitrogenase enzyme is also added. The model is successfull
Background: Respiratory symptoms are common in the general adult population. Increased burden of respiratory symptoms may increase the risk of mortality. We assessed the association between respiratory symptom clusters and mortality. Methods: Participants were derived from two population-based Swedish adult cohorts (N = 63,060). Cluster analysis was performed with Locality Sensitive Hashing (LSH)-
Esophageal lesions are common findings in disorders of the digestive tract in patients living with HIV, the most typical symptoms being odynophagia and/or dysphagia. This article provides a narrative review of the spectrum of esophagitis in patients living with HIV, focusing on fungal, viral, bacterial and non-infectious etiologies, as well as co-infections with viral hepatitis viruses. The articl
Objective: The objective of this study was to evaluate the applications and procedures of perioperative antibiotic prophylaxis (PAP) in terms of their cost and efficacy in a state hospital in Turkey. Setting: A 372-bed, state hospital in Isparta, Turkey. Method:The investigation was performed between May and August 2011 in six surgical wards. All of the surgical procedures were followed up and ant
BACKGROUND: It is unclear how diabetes and metformin use is associated with survival of esophageal cancer.METHODS: This population-based cohort study included new cases of esophageal cancer reported in Sweden from 2006 to 2018 with follow-up through 2019. Diabetes status and metformin use were analyzed in relation to all-cause and disease-specific mortality using multivariable Cox regression. The
In recent years, it has been shown that deep eutectic solvents (DES) and similar mixtures solvate and allow for self-assembly of surfactants, serving as potential “green” alternatives as solvents for, for example, templating nanomaterials or drug delivery applications. Which surfactants are soluble and how they self-assemble depends strongly on the mixture components and their molar ratio. He
Background: The imbalance between proteases and anti-proteases is considered to contribute to the development of COPD. Our aim was to evaluate the protease MMP-9, the antiprotease TIMP-1 and the MMP-9/TIMP-1-ratio as biomarkers in relation to prognosis. Prognosis was assessed as lung function decline and mortality. This was done among subjects with COPD in a population-based cohort. Methods: In 20
Introduction. There is no water-tight division between different categories of human rights. In particular, it is important to note that although the project of transforming the 1948 Universal Declaration of Human Rights into treaty form culminated in separate Covenants including, on the one hand, civil and political Rights and, on the other hand, economic, social and cultural Rights, it did not r
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)
What do we know about youth climate activism in India? Given the country’s rich history of environmental activism and the recent increase in youth climate groups, the literature on youth climate activism in India is surprisingly scant. The present review systematically identified eight studies focusing specifically on young people’s climate activism in India post-2019. An in-depth comparative read
In this study, we report on reactive large-eddy simulations (LESs) of flow and combustion in the U.S. Air Force Research Laboratory Research Cell 19 cavity-based scramjet combustor. This case involves the combustion of ethylene that is injected into a cavity. It has previously been studied experimentally with multiple techniques, including particle image velocimetry, hyperspectral imagining, and l
The frequency modulation transfer property of a backward-wave optical parametric oscillator (BWOPO) is investigated in the context of near-IR pulse compression. The maximum transferrable bandwidth from the pump to the forward wave in a BWOPO is determined by the group dispersion mismatch. In comparison, the third-order phase introduced in a single-grating compressor setup is more detrimental to ac
The strict momentum conservation constraints for backward-wave optical parametric oscillators (BWOPOs) gives an inherently narrowband backward-generated wave, even with broadband pumping. Unfortunately, the limited tuning range of this wave restricts potential applications. Here we demonstrate a method to circumvent this restriction and increase the tuning range by more than one order of magnitude
We report pulse energy scaling enabled by the use of Laguerre-Gaussian single-vortex (LG0,l) beams for spectral broadening in a sub-40 cm long Herriott-type bulk multi-pass cell. Beams with orders l=1−3 are generated by a spatial light modulator, which facilitates rapid and precise reconfiguration of the experimental conditions. 180 fs pulses with 610 uJ pulse energy are post-compressed to 44 fs u
Greenwashing is on the rise as a strategy for maintaining business-as-usual through false ecological claims. This paper articulates an approach to the study of greenwashing guided by the philosophy of critical realism. In its first move, it identifies greenwashing as depending on the possibility of socially conflating the relation between transitive and intransitive objects of knowledge. The paper
