We report a spatially resolved spectroscopic study of the visible chemiluminescence emission from different premixed ammonia-air-oxygen flames stabilized on a laminar flat flame burner, with equivalence ratio ranging from 0.7 to 1.35 and an O2/N2 ratio of 0.4. In the reaction zone of the observed flames, the visible emission was recognized to be the chemiluminescence of excited NH2* radicals, whil

Echocardiographic quantification of myocardial perfusion after IV contrast is possible, based on the intensity of the received intermittent second harmonic signal. To investigate the influence of respiration on the intensity of myocardial signals, we examined nine patients with normal coronary angiograms. At baseline, end-expiratory and end-inspiratory images were obtained in broadband radiofreque

To reach a broader understanding of person-environment relationships as building blocks for universal design in research and practice, this paper combine and discuss three types of interaction between individuals and environments - instrumental, non-instrumental, and non-physical - and five constituent concepts, i.e. accessibility, usability, aesthetic experience, the experience of meaning and emo

Purpose: Positron emission tomography-computed tomography (PET-CT) using prostate-specific membrane antigen (PSMA) ligands is a method for imaging prostate cancer. A recent tracer, 18F-PSMA-1007, offers advantages concerning production and biokinetics compared to the standard tracer (68Ga-PSMA-11). Until now, radiation dosimetry data for this ligand was limited to the material of three healthy vol

Summary: The existing information supports the use of this material as described in this safety assessment. 2-Phenylpropionaldehyde was evaluated for genotoxicity, repeated dose toxicity, developmental and reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data on read-across analogs 3-phenylbutanal (CAS # 16251-77-7)

The use of protective barriers to isolate a metal surface from an aggressive environment is a common way to inhibit its degradation. We used ambient pressure x-ray photoelectron spectroscopy to assess in real time the evolution of the copper surface and the contextual protective action of 2D material coatings (graphene and hexagonal boron nitride) towards copper oxidation. In an isobaric experimen

A combined two-levels control method has been developed and tested on a long term operation of a two-phases pilot-scale anaerobic process for the concurrent production of volatile fatty acids, hydrogen and methane. The latter was designed for the treatment of food waste of urban origin (namely, the organic fraction of municipal solid waste). The optimized control method was set on the base of the

In the study of trade-embedded environmental factors (land, water, energy, or material flows), three conflicting interpretations prevail concerning what happened before 1950. The 'great specialization' narrative argues that trade served to lighten pressure on the environment by redistributing environmental services from where they were abundant to where they were scarce. The 'great divergence' see

Atopic dermatitis (AD) is a disease that can have a high impact on quality of life, especially due to itch and skin pain. This paper utilizes expertise from members of the International Society of Atopic Dermatitis (ISAD)/Oriented Patient-Education Network in Dermatology (OPENED) task force to review the epidemiology, pathophysiology and exacerbating factors of itch and pain in atopic dermatitis.

Individuals with cancer may be at high risk for coronavirus disease 2019 (COVID-19) and adverse outcomes. However, evidence from large population-based studies examining whether cancer and cancer-related therapy exacerbates the risk of COVID-19 infection is still limited. Data were collected from the COVID Symptom Study smartphone application since March 29 through May 8, 2020. Among 23,266 partic

Introduction: This study examined the prevalence of and risk factors for a prolonged passive second stage of labor in nulliparous women. Material and Methods: This was a historical cohort study of all nulliparous women (n = 1131) at two delivery units in Sweden. Maternal and obstetric data were obtained from electronic medical records during 2019. Duration of the passive second stage was measured

Behandlar Margareta Hansdotter (1594-1657), den faktiska dokumentationen av hennes liv och den omfattande tolkningen och användningen av hennes gestalt såväl inom den lutherska traditionen (del I) som de sekulära omtolkningarna av henne i olika syften fram till idag (del II).

BACKGROUND: Although gambling disorder is traditionally considered an adult phenomenon, the behavior usually begins in childhood or adolescence.OBJECTIVE: The aim of this study was to explore the frequency of problem gambling among Swedish adolescents and the suspected associated factors.METHODS: This study was based on data collected through a public health survey distributed in 2016 to pupils in

A chronicle describing the historical context and the development of ideas and experiments leading to the discovery of the back-bending phenomenon in rapidly rotating atomic nuclei some 50 years ago is presented. The moment of inertia of some atomic nuclei increases anomalously at a certain rotational frequency, revealing important clues to our understanding of nuclear structure. I highlight the d

This chapter is based on a document analysis of 632 issues of the Danish Bar and Law Society’s trade magazine published from 1976-2018, and interviews with lawyers from the Scandinavian countries. The empirical findings concerning the structures and rationales dominating and defining the trajectory of lawyers’ voluntary work for the last four decades suggest that voluntary work targeted at those m

Ramadan fasting is observed by most of the 1.8 billion Muslims around the world. It lasts for 1 month per the lunar calendar year and is the abstention from any food and drink from dawn to sunset. While recommendations on 'safe' fasting exist for patients with some chronic conditions, such as diabetes mellitus, guidance for patients with cardiovascular disease is lacking. We reviewed the literatur

Thoracic epidural analgesia (TEA) is an established gold standard for postoperative pain control especially following laparotomy and thoracotomy. The safety and efficacy of TEA is well known when the attention to patient selection is upheld. Recently, the use of fascial plane blocks (FPBs) has evolved as an alternative to TEA most likely because these blocks avoid problems such as neurological com

This paper presents the results from a longitudinal study of the process of developing and implementing a method for risk assessment in a public sector organisation over a period of 3.5 years. The study explores how people involved in this process viewed factors influencing the implementation and what effects the risk management process gave rise to. While a large share of previous research on thi
