Numerical simulation of microwave-enhanced methane-air flames I : Modeling and one-dimensional premixed laminar flames

This study considers the numerical modeling of sub-breakdown microwave-enhanced combustion in one-dimensional laminar methane-air flames over a range of stoichiometries at standard temperature and pressure. The effect of uniform microwave fields on the laminar flame speed, post-flame temperature and composition is of primary interest here. A model for the non-thermal plasma generated by the microw

Learning and community building in support of collective action : Toward a new climate of communication at the COP

The international UN Climate Change conferences known as “Conferences of the Parties (COPs)” have an enormous convening power and are attended annually by tens of thousands of actors working on climate change topics from a wide range of perspectives. In the COP spaces outside of the formal negotiations, the communication culture is dominated by “side events,” a format that relies heavily on conven

Estimating the probability distributions of radioactive concrete in the building stock using Bayesian networks

The undesirable legacy of radioactive concrete (blue concrete) in post-war dwellings contributes to increased indoor radon levels and health threats to occupants. Despite continuous decontamination efforts, blue concrete still remains in the Swedish building stock due to low traceability as the consequence of lacking systematic documentation in technical descriptions and drawings and resource-dema

Influence of Manufacturing Error Tolerances on Thermal EHL Behavior of Gears

Due to the electrification of vehicles, new demands are being imposed on gears, which translates to the tolerances of manufacturing errors. However, not many studies treat the impact of manufacturing error combinations on the lubricant behavior of gear sets. Therefore, a simulation method is developed, including its derivation, discretization, and implementation. The method solves the thermal elas

DNA Methylation and Gene Expression of the Cysteinyl Leukotriene Receptors as a Prognostic and Metastatic Factor for Colorectal Cancer Patients

Colorectal cancer (CRC), one of the leading causes of cancer-related deaths in the western world, is the third most common cancer for both men and women. As a heterogeneous disease, colon cancer (CC) is caused by both genetic and epigenetic changes. The prognosis for CRC is affected by a variety of features, including late diagnosis, lymph node and distant metastasis. The cysteinyl leukotrienes (C

Independent Evidence for the Preservation of Endogenous Bone Biochemistry in a Specimen of Tyrannosaurus rex

Biomolecules preserved in deep time have potential to shed light on major evolutionary questions, driving the search for new and more rigorous methods to detect them. Despite the increasing body of evidence from a wide variety of new, high resolution/high sensitivity analytical techniques, this research is commonly met with skepticism, as the long standing dogma persists that such preservation in

Experimental study on the pull-down performance of a −80°C cascade refrigeration freezer

To cope with global climate change, chlorofluorocarbons and hydrofluorocarbons refrigerants have been or will be abandoned by different countries worldwide. Natural refrigerants seem to be promising substitutes in the near future. In this study, eco-friendly refrigerants R290 and R170 are adopted as high-temperature and low-temperature fluid in a cascade refrigeration freezer to generate −80°C. Th

Geometrical and environmental effect on fire behaviour of polyurethane foam slabs

This study presents the results of a set of large-scale fire tests performed on horizontal polyurethane foam slabs. Slab thickness, ignition location, and environment (free burn or corner wall) were varied over 23 individual tests. In a continuation of a previous study by the authors, four different slab thicknesses, five different ignition locations, and three environmental modification combinati

Locality in the Promoted Sustainability Practices of Michelin-Starred Restaurants

Sustainable practices are increasingly promoted in the restaurant industry. One significant aspect of sustainability in restaurants is the use of local supply chains, especially for food, which also serve as a means for restaurants to promote freshness of produce, sourcing, and quality. Considering the prevalence of locality in menu marketing, this study aims to explore the relationships between s

Investigating Validity of Semantic Measures vs Rating Scales in Assessing Personality

Within personality research, self-report questionnaires are a common approach. This study takes aim at investigating whether self-report questionnaires are enough, or if semantic measures, through Natural Language Processing, could be a substitute or complementary method, in assessing personality. Based on the Five Factor Model of personality, this study has been divided into two phases. Participa

Synchrotron XPS and Electrochemical Study of Aging Effect on Passive Film of Ni Alloys

To investigate aging effect on the passive film of Ni23Cr15Mo and Ni22Cr9Mo3Nb, synchrotron-based X-ray photoelectron spectroscopy (XPS) was used to analyze the structure and composition of the air-formed passive film on the alloys. The corrosion resistance of the two Ni alloys in 1 M NaCl solution was evaluated with electrochemical cyclic polarization measurement. The synchrotron XPS measurement

Experiences of Using Weighted Blankets among Children with ADHD and Sleeping Difficulties

Introduction. Sleeping difficulties are common in children with attention deficit hyperactivity disorder (ADHD). A sleep intervention with weighted blankets was designed to increase current understanding of using weighted blankets to target children’s individual needs in connection with sleep and daytime functioning. Aim. To explore how children with ADHD and sleeping difficulties experience the u
