Revised and extended analysis of Ga II

The gallium spectrum emitted from a hollow cathode has been recorded in the region 500-9800 A. 142 lines have been classified as transitions in Ga II. Energy levels have been derived from the observations, and perturbations within the n = 4 configuration complex are discussed. Besides the previously known mixing between 4s4d and 4p2, it has been found that the structure of 4s4/is strongly affected

The use of a novel short dilator tip on the distal bifurcated component during fenestrated aortic repair to avoid reno-visceral bridging stents

BACKGROUND: The aim of this study was to evaluate the feasibility and efficacy of a modified delivery system of the distal bifurcated FEVAR component where the dilator tip was shortened to prevent damage to the renovisceral bridging stents.METHODS: All consecutive patients from a tertiary referral center that underwent a FEVAR with a custom delivery system of the distal bifurcated endograft with a

Heterogeneity in the associations between common mental disorders and labour outcomes - a population study from southern Sweden

BACKGROUND: Previous research has shown that Common Mental Disorders (CMD) are unequally distributed between population subgroups, but we know less about how labour outcomes following such disorders are distributed. Our aim is to investigate how the labour outcomes following a CMD diagnosis differ over sex, age, schooling and country of birth.METHODS: We use a population sample from southern Swede

Ógle Wakȟáŋ Kiŋ : Relational materiality and the Lakota Ghost Dance of 1890

This article examines the materiality of the Ghost Dance shirt – ógle wakȟáŋ kiŋ – among the Lakota, and its associated symbols and functions. By cross-referencing sources on the Ghost Dance to sources on traditional Lakota belief and ritual, it is shown that the practice of interrituality – the use of established ritual elements and acts in novel contexts – enabled traditional ritual dynamics and

Critical review on anti-obesity effects of phytochemicals through Wnt/β-catenin signaling pathway

Phytochemicals have been used as one of the sources for the development of anti-obesity drugs. Plants are rich in a variety of bioactive compounds including polyphenols, saponins and terpenes. Phytochemicals inhibit adipocyte differentiation by inhibiting the transcription and translation of adipogenesis transcription factors such as C/EBPα and PPARγ. It has been proved that phytochemicals inhibit

Temporal temperature measurement on burning biomass pellets using phosphor thermometry and two-line atomic fluorescence

We report accurate in-situ optical measurements of surface temperature, volatile gas temperature, and polycyclic aromatic hydrocarbon (PAH) emission over the whole burning history of individual biomass pellets in various combustion atmospheres. Two biomass fuels, wood and straw, were prepared in cylindrical pellets of ~300 mg. The pellets were burned in a well-controlled combustion atmosphere prov

Rationale and design of switch Swedeheart : A registry-based, stepped-wedge, cluster-randomized, open-label multicenter trial to compare prasugrel and ticagrelor for treatment of patients with acute coronary syndrome

Background: European treatment guidelines recommend prasugrel over ticagrelor for treating patients with non–ST-elevation acute coronary syndrome (ACS), prompting several Swedish administrative regions to transition from ticagrelor to prasugrel as the preferred treatment for patients with ACS. We aim to systematically evaluate this transition to determine the relative efficacy of prasugrel versus

Inferior Vena Cava-Balloon Occlusion and Its Effect on the Myocardium During Endograft Deployment in the Arch

AbstractPurpose: To evaluate the impact of cava balloon occlusion on the myocardium during endovascular repair of thoracic aortic pathologies.Material and methods: A prospective observational cohort study of 21 patients who underwent endovascular repair of aortic arch and thoracic aorta in a single tertiary referral center with use of inferior vena cava (IVC) balloon occlusion as a method of intra

Combined fracture and mortality risk evaluation for stratifying treatment in hip fracture patients : A feasibility study

Objectives: This study aims to test the feasibility of the Fracture and Mortality Risk Evaluation (FAME) Index. Patients and methods: Two academic centers in Lithuania and Turkey participated in this retrospective study conducted between November 2018 and July 2019. A total of 100 consecutive patients (22 males, 78 females; mean age 78.9 years; range, 45 to 100 years) with low energy proximal femu

Supporting cross-domain system-level environmental and earth science

Answering the key challenges for society due to environmental issues like climate change, pollution and loss of biodiversity, and making the right decisions to tackle these in a cost-efficient and sustainable way requires scientific understanding of the Earth System. This scientific knowledge can then be used to inform the general public and policymakers. Scientific understanding starts with havin

Remote sensing in urban planning: : Contributions towards ecologically sound policies?

Remote sensing has evolved to become a key tool for various fields of environmental analysis, thus actively informing policy across areas and domains. To evaluate the degree to which remote sensing is contributing to the science of ecologically-oriented urban planning, we carried out a systematic literature review using the SCOPUS database, searching for articles integrating knowledge in urban pla

What to share, when, and where : balancing the objectives and complexities of open source software contributions

Context:: Software-intensive organizations’ rationale for sharing Open Source Software (OSS) may be driven by both idealistic, strategic and commercial objectives, and include both monetary as well as non-monetary benefits. To gain the potential benefits, an organization may need to consider what they share and how, while taking into account risks, costs and other complexities. Objective:: This st

Consensus statement on the definition of orthostatic hypertension endorsed by the American Autonomic Society and the Japanese Society of Hypertension

We propose a consensus definition of "an exaggerated orthostatic pressor response" in subjects in whom systolic blood pressure increases ≥ 20 mmHg when going from supine to standing posture. This definition can be extended for seated to standing measurements. We reserve the term "orthostatic hypertension" for when this pressor response leads to an upright systolic blood pressure ≥ 140 mmHg. We bel

Spell new sounds with new letters : A study of how Swedish L2 learners’ spelling is affected by their L1

The current study examines whether there is a connection between Swedish L2 students' L1 and their spelling in Swedish.The data were collected through a spelling test conducted at SFI course levels C and D. The experiment was conducted in an urban area in Småland in three groups consisting of 37 course participants with 12 different L1s. People with Arabic as their L1 are the focus of the study du

Photoacoustic imaging for non-invasive examination of the healthy temporal artery - systematic evaluation of visual function in healthy subjects

PURPOSE: Photoacoustic (PA) imaging has the potential to become a non-invasive diagnostic tool for giant cell arteritis, as shown in pilot experiments on seven patients undergoing surgery. Here, we present a detailed evaluation of the safety regarding visual function and patient tolerability in healthy subjects, and define the spectral signature in the healthy temporal artery.METHODS: Photoacousti

Measurement Characterization of Aperture Correction Technique for EMF

Techniques for accurate, robust and efficient over-the-air testing for devices in the next generation communication system are important. This work aims at presenting the use of an aperture calibration technique, through which field values and power density values are reconstructed at an arbitrary plane in the near-field from a measurement of a separate plane for devices operating in 28-60 GHz.
