Microfluidic systems have witnessed rapid development in recent years. As one of the most common structures, the micro-orifice is always included inside microfluidic systems. Hydrodynamic cavitation in the micro-orifice has been experimentally discovered and is harmful to microfluidic systems. This paper investigates cavitating flow through a micro-orifice. A rectangular micro-orifice with a l/d r

Background: Hepatitis B virus (HBV) is an important infectious cause of morbidity and mortality in Jordan. HBV genotype D is the most prevalent in the country. Virus escape mutants in the HBV S region is an important public health problem halting preventive efforts. The aim of the current study was to investigate patterns of HBV escape and resistance mutations and to assess domestic transmission o

Drinking stories feature widely in Western societies. Many people eagerly share their stories in the aftermath of drinking events. These stories are also common in books, movies, music and the media. Based on qualitative interviews with 104 young Norwegian heavy episodic drinkers, the article seeks to establish drinking stories as a distinct narrative genre. We argue that this narrative genre of d

Based on interviews with 104 young partygoers, this article examines sexual assaults that occur in the context of festive events. Focus is on how individuals describe their sexual victimization. Three experiential characteristics stand out in the victims’ accounts. First, the assaults are described as being characterized by an altered state of consciousness, primarily alcohol-related intoxication.

Most Western countries have laws that prohibit the serving of alcohol to intoxicated and underage patrons in nightlife venues such as pubs and nightclubs. Despite laws and the implementation of server training programs, several studies have shown that intoxicated patrons are still likely to be served. This think-piece article attempts to shed new light on the tendency among bartenders to overserve

Background In this study, we use assemblage theory to investigate the link between alcohol use and one-night stands. Methods The data come from qualitative interviews conducted with 104 young participants in the night-time economy. Results We show that: (i) alcohol-fuelled sexual explorations (e.g. erotic fantasizing, flirting and sex) are of paramount importance for young partygoers; (ii) sexuali

Every year, millions of young people travel away from home to party for days or weeks on end in permissive environments, such as music festivals, dance parties, and nightlife resorts. The studies that have been conducted on these extended youth parties have focused primarily on specific risk-taking behaviors, such as drug use and violence. Here, we scrutinize the research on extended youth parties

Violence features in human life, not only as actual physical confrontation but also as stories. Stories of violence are particularly important in violence-prone subcultures and among those partaking in the illegal drug economy. Drawing on narrative analysis, this study examines stories of violence among a population of incarcerated Norwegian drug dealers. Four widespread story types are identified

Drawing on the classical crowd theories of Tarde, Le Bon, Durkheim, and Canetti, this article examines pub crawl crowds at the Bulgarian nightlife resort, Sunny Beach. The article argues that there are elements in classical crowd theory which can be used to advance the current research on tourist crowds such as those at pub crawls. The main strength of the theories lies in their ability to bring u

Aims: The use of illegal drugs is well documented in some alternative, underground music scenes, like the Goa trance scene. The aim of this article is to explore harm reduction practices employed by attendees of the Goa trance scene in order to identify potential pathways for targeted interventions in (underground) music scenes, such as Goa trance.Methods: Following pilot observations at Goa parti

Objectives: We evaluated the diagnostic performance of quantitative flow ratio (QFR) assessment of nonculprit lesions (NCLs) based on acute setting angiograms obtained in patients with ST-segment elevation myocardial infarction (STEMI) with QFR, fractional flow reserve (FFR), and instantaneous wave-free ratio (iFR) in the staged setting as reference. Background: QFR is an angiography-based approac

Purpose Over the last decade a substantial pool of research has emerged on bouncers and their influence on the safety conditions in nightlife environments. Comparatively little, however, has been written on bouncers themselves and their working conditions. The purpose of this paper is to identify the perceived risks, stress and other work-related problems among bouncers working in Danish nightlife

Kärn- och elektrondynamik i atomer och molekyler är grunden för många fysiska processer och kemiska reaktioner. Ofta händer denna dynamik på tidsskalor som är så korta att de kallas ultrasnabba.För att studera ultrasnabba fenomen behövs tekniker som pump-prob-experiment med ultrasnabba ljuspulser. För att dessa experiment ska lyckas måste ljuspulsernas egenskaper noga studeras och styras för att dNuclear and electronic dynamics in atoms and molecules are the foundation of many physical processes and chemical reactions. Often, these dynamics take place on timescales so much shorter than those commonly encountered that they are called ultrafast. In order to study ultrafast phenomena, time-resolved techniques such as pump-probe experiments, involving ultrafast light pulses, are necessary. Fo

Aims: To study the characteristics, contexts and implications of drinking stories among young drinkers. Methods: Ethnographic fieldwork was conducted among Danish youth at a beach resort in Bulgaria. The fieldwork included three months of participant observation and 45 semi-structured interviews with a total of 104 tourists and 11 guides. The participants in the study were aged between 16 and 26 y
