In this work, the effect of a pin as a secondary surface mounted on hydrothermal behavior of impinging jet over a flat plate investigated numerically and experimentally. The transient three-dimensional turbulent flow is simulated by the Renormalization Group (RNG) k − ɛ model. The injection air is pulsed by square waves. In a radial arrangement, several differently shaped pins (i.e., circular, ell
The evolution of sex chromosomes is hypothesized to be punctuated by consecutive recombination cessation events, forming “evolutionary strata” that ceased to recombine at different time points. The demarcation of evolutionary strata is often assessed by estimates of the timing of recombination cessation (tRC) along the sex chromosomes, commonly inferred from the level of synonymous divergence or w
The present study aims to investigate boiling heat transfer enhancement on coated surfaces, based on mechanistic models. An electrochemical deposition method was used to fabricate coatings on copper surfaces which enhance critical heat flux and heat transfer coefficient of deionized water by 35.5% and 40.1%, respectively, compared with a smooth surface. Bubble dynamics indicates that regardless of
What makes people affectively polarized? Affective polarization is based on the idea that partisanship can be a social identity leading to polarization in the form of intergroup distancing between the own party and the other parties. In this study, we argue that perceived threats from an outgroup can spur affective polarization. To investigate this, we use the issue of immigration, often framed as
The aim of this study was to investigate how different types of motivation to defend victims of bullying would be associated with various bystander behaviors in cyberbullying situations among early adolescents in Sweden. Data were collected from 460 Swedish adolescents aged between 11 and 15 years who completed a survey in their classroom. Results showed that autonomous motivation to defend was po
This study addresses the role of natural hazard insurance in two European countries with different insurance markets and socioeconomic conditions: Sweden and Portugal. The analyses were conducted at the national, regional (Southern Sweden and Lisbon Metropolitan Area - LMA), and local (Malmö and Lisbon cities) scales. Most damage caused by weather and climate-related (WCR) hazards during the 1980-
Sinus tachycardia (ST) is ubiquitous, but its presence outside of normal physiological triggers in otherwise healthy individuals remains a commonly encountered phenomenon in medical practice. In many cases, ST can be readily explained by a current medical condition that precipitates an increase in the sinus rate, but ST at rest without physiological triggers may also represent a spectrum of normal
OBJECTIVE: Diagnostic criteria for ambulatory blood pressure monitoring (ABPM) in patients with suspected reflex syncope are lacking. We hypothesized that patients with reflex syncope have a higher prevalence of systolic blood pressure (SBP) drops on ABPM. DESIGN AND METHOD: We conducted a retrospective analysis comparing ABPM data from reflex syncope patients and controls, matched by average 24-h
This study investigates 30 lone actors in Sweden with a register-based design using a group of male lone actors and two reference groups: same-sex siblings and other male violent extremists. We compare lone actors to the reference groups along social background, criminal background, and co-offending relations (1995 –2016), and mental health (1980–2016). Our results show that lone actors are primar
While the economic impact of China’s ‘Belt and Road’ Initiative (BRI) in Sri Lanka has been closely monitored in recent years, few studies have focused on the role of China’s Buddhist narratives in furthering the countries’ interests. By analyzing the Buddhist strategic narratives used in official Chinese and Sri Lankan statements, this article argues that under the BRI’s ‘people-to-people’ bonds,
The article introduces "the visceral novel reader" as a diachronic, context-sensitive mode of novelistic reception, in which fact and fiction overlap cognitively: the mental rehearsal of the activity of seeing, hearing, smelling, tasting, and touching while reading novels and, vice versa, the mental rehearsal of novels in the act of perceiving the real world. Located at the intersection of literat
To historians of medicine, Karl Philipp Moritz is known as the founding editor of the Magazine for Empirical Psychology (1783–93), one the oldest psychiatric journals in Europe. In literary theory, Moritz counts as one of the inaugurators of aesthetic autonomy. Combining both fields, this article uncovers that Moritz’s interest in observation, his reservations towards rationality, and his concern
This article outlines a number of new approaches in the history of medicine and medical humanities to the study of medical case histories from a genre-theoretical vantage point. Differentiating between morphological and structuralist concepts of genre, the essay proposes the investigation of similarities and differences among specific series of case histories in order to recover evolving, changing
Climate changes, tightly linked to anthropogenic activities, are significantly altering environments and ecosystems globally, such as by increasing marine and coastal deoxygenation or occurrences of extreme weather events. The significance of paleoenvironmental and -climate reconstructions, as well as monitoring of current conditions, for unravelling baseline natural variation, today’s changes and
The Romance of the Forest (1791) secured Ann Radcliffe’s reputation as a writer of Gothic literature. The novel continued and expanded, as this chapter will show, the Walpolean tradition of re-evaluating the modern romance by injecting it with the virtues of “respectable” novels such as plausibility, mimetic acuity and Protestantism. After a brief recapitulation of Radcliffe’s theory of the supern
