Inlet layout effects on the mixing performance with a novel mixing evaluation in a powder-fueled ramjet

Mixing process is crucial for ignition and combustion in powder-fueled ramjets. The mixing performance depends mainly on the inlet layout. In this study, the effects of four popular inlet layouts were investigated and were found to significantly influence the particle distribution. In this study, the Savitzky-Golay approach was used to handle large amounts of data on particles to obtain clear peak

Experimental and kinetic modeling study of the CH4+H2S+air laminar burning velocities at atmospheric pressure

With the increasing demand for natural gas and depletion of many sweet gas fields, direct usage of sour gas, usually containing a large percentage of hydrogen sulfide (H2S), becomes a more economical choice in recent years. However, the laminar burning velocity (SL) of CH4+H2S flames have seldom been investigated due to the corrosivity and toxicity of H2S, and no available experimental data can be

Major adverse cardiovascular events following acute coronary syndrome in patients with bipolar disorder

Background: Persons with bipolar disorder (BD) have a higher cardiovascular mortality compared to the general population, partially explained by the increased burden of cardiovascular risk factors. Research regarding outcomes following acute coronary syndrome (ACS) in this population remains scarce. Design: This Danish register-based study included patients diagnosed with BD and ACS in the period

Mental health and psychosocial consequences linked to radiation emergencies - Increasingly recognised concerns

A major radiological or nuclear emergency may, apart from causing a substantial loss of life and physical damage, also put a substantial strain on affected societies with social, economic and political consequences. Although such emergencies are relatively uncommon, it is now being increasingly recognised that their subsequent psychosocial impact can be widespread and long lasting. Mental health e

Bottlenose dolphin communication during a role-specialized group foraging task

A division of labor with role specialization is defined as individuals specializing in a subtask during repetitions of a group task. While this behavior is ubiquitous among humans, there are only four candidates found among non-eusocial mammals: lions, mice, chimpanzees, and bottlenose dolphins. Bottlenose dolphins in the Cedar Keys, Florida, engage in role specialized “driver-barrier feeding”, wh

Dancing all the way to the stage by way of the stadium : on the iconicity and plasticity of actions

In the sense of phenomenology, actions are special cases of acts of consciousness. Within semiotics, first Jan Mukařovský and then A. J. Greimas have established, in different terms, a distinction between instrumental actions and actions which carry their meaning in themselves. But this is insufficient to account for the variety of actions which comprises everything from the creation of artefacts,

Prenatal interventions for fetal growth restriction in animal models : A systematic review

Fetal growth restriction (FGR) in human pregnancy is associated with perinatal mortality, short- and long-term morbidities. No prenatal therapy is currently established despite decades of research. We aimed to review interventions in animal models for prenatal FGR treatment, and to seek the next steps for an effective clinical therapy. We registered our protocol and searched MEDLINE, Embase, and T

Emerging drugs for the treatment of bladder storage dysfunction

Introduction: Current drug treatment of lower urinary tract disorders, for example, overactive bladder syndrome and lower urinary tract symptoms associated with benign prostatic hyperplasia, is moderately effective, has a low treatment persistence and some short- and long-term adverse events. Even if combination therapy with approved drugs may offer advantages in some patients, there is still a ne

Illicit Trafficking of Cultural Properties in Arab States

The present edited research aims to capture a bird’s-eye view of the phenomenon of illicit trafficking of cultural properties and to serve as a reference point for governments, enforcement agencies, international organizations, stakeholders, and civil societies. The targeted geographic region is the Arab World, the countries in the Middle East, Arabic Gulf, Horn of Africa and North Africa. There i

The Glucose Sensitivity of Insulin Secretion-Lessons from In Vivo and In Vitro Studies in Mice

This study explored the relationship between the glucose dose and insulin response from beta cells in vivo and in vitro in mice. Glucose was administered intravenously at different dose levels (from 0 to 0.75 g/kg) in anesthetized C57BL/6J mice, and the glucose and insulin concentrations were determined in samples taken after 50 min. Furthermore, freshly isolated mouse islets were incubated for 60

‘The Vanity of Translation’; or, Locating Adam Oehlenschläger in Romantic-Period Europe

Cian Duffy’s chapter is concerned with the Danish poet and dramatist Adam Oehlenschläger, often identified as Denmark’s leading Romantic-period writer. Duffy focuses on an early instance of Oehlenschläger’s reception in England: an essay on contemporary German drama by Julius Charles Hare in the first and only number of Charles Ollier’s Literary Miscellany. Drawing also on theories about the relat

Heraqla, between the dream of Harun Al Rashid and the nightmare of the looters

The archaeological site of Heraqla in Raqqa represents a particular example of the Abbasid architecture; the Caliph Harun Al Rashid started reconstructing it as a commemorative monument but after his death it was never completed. The Directorate General of Antiquities and Museums DGAM excavated in the site, constructed furnace to produce bricks similar to the ancient material for restorations and,

Insights from Central Syrian Desert on the migration routes of Homo erectus from Africa to Eurasia during the Paleolithic

Our knowledge regarding the migration of the Homo erectus towards Eurasia and the routes he took through the Middle East during the Paleolithic is limited. The latest surveys and excavations at sites in the central Syrian Desert have revealed important data on these routes. Archaeological labor documented numerous archaeological sites located between the Mount Bishri and the Middle Euphrates Valle

Domain Decomposition for Non-smooth (in Particular TV) Minimization

Domain decomposition is one of the most efficient techniques to derive efficient methods for large-scale problems. In this chapter such decomposition methods for the minimization of the total variation are discussed. We differ between approaches which directly tackle the (primal) total variation minimization and approaches which deal with their predual formulation. Thereby we mainly concentrate on

IDAC-Bio, A Software for Internal Dosimetry Based on the New ICRP Biokinetic Models and Specific Absorbed Fractions

ABSTRACT: Radiation dosimetry is central to virtually all radiation safety applications, optimization, and research. It relates to various individuals and population groups and to miscellaneous exposure situations-including planned, existing, and emergency situations. The International Commission on Radiological Protection (ICRP) has developed a new computational framework for internal dose estima

Mary Howitt’s Translation of Hans Christian Andersen’s Fairy Tales

Hannah Persson’s essay looks at the early reception in England of Denmark’s most famous writer Hans Christian Andersen, showing how Andersen was (mis)represented in England as a result of the particular inflection given to his work by his translator, Mary Howitt. Examining Howitt’s praxis as a translator, Persson concludes that her (mis)understanding of Andersen’s tales as primarily intended for c

Restricted X chromosome introgression and support for Haldane's rule in hybridizing damselflies

Contemporary hybrid zones act as natural laboratories for the investigation of species boundaries and may shed light on the little understood roles of sex chromosomes in species divergence. Sex chromosomes are considered to function as a hotspot of genetic divergence between species; indicated by less genomic introgression compared to autosomes during hybridization. Moreover, they are thought to c

Employment and Structural Change : Economic Integration of Immigrants in the Swedish and Malmo Labour Markets 1970-1990

Sweden developed during the first two decades of the post-war period into one of the wealthiest countries in the world. This change in the wealth of the country was accompanied by immigration on a previously unknown scale. Sweden’s remarkable economic growth has been facilitated by this immigrant flow, which consisted almost entirely of European labour migrants during the period up to the early 19

The interplay between deformation and deposition in a Pleistocene push moraine : New insight from structural interpretation and area-depth-strain analysis of the growth strata

There are many examples suggesting that push moraine formation requires building up of the proglacial wedge and then post-depositional folding and/or faulting. Only a few studies have been carried out on syntectonic deposition and erosion within proglacial sediment wedges; however, the resulting growth strata were determined based on the high variability in thickness and occurrence of erosional un
