In this paper we provide insight into the thermophysical properties and the dynamics of cryogenic jets. The motivation of the work is to optimise the use of cryogenic fluids in novel ultra low emission engines. For demonstration, we use conditions relevant to an internal combustion engine currently being developed by Dolphin N2 and the University of Brighton, the CryoPower recuperated split cycle engine (RSCE). The principle of this engine is a split-cycle combustion concept which can use cryogenic injection in the compression cylinder to achieve isothermal compression and thus help maximise the efficiency of the engine. Combined experimental and numerical findings are presented and the effects of atomisation dynamics of the LN 2 are explored at both sub- and supercritical conditions in order to cover different pressure and temperature conditions representative of the engine compression cycle. For subcritical regimes, we observe that the appearance of the jet coincides with the predicted atomisation regimes based on the Weber, Ohnesorge and Reynolds numbers for other common fluids. For the modelling of supercritical jets, a new methodology within OpenFoam which accounts for Real Fluid Thermodynamics has been developed and the jet behaviour under various pressure and temperature conditions has been investigated. To our knowledge this is the first study where a cryogenic spray process evolution is examined for conditions relevant to the ones prevailing in a compression chamber accounting for both sub and supercritical conditions.

ABSTRACT Many people may not be aware of the extent of Kurt Kyser's collaboration with mineral exploration companies through applied research and the development of innovative exploration technologies, starting at the University of Saskatchewan and continuing through the Queen's Facility for Isotope Research. Applied collaborative, geoscientific, industry-academia research and development programs can yield technological innovations that can improve the mineral exploration discovery rates of economic mineral deposits. Alliances between exploration geoscientists and geoscientific researchers can benefit both parties, contributing to the pure and applied geoscientific knowledge base and the development of innovations in mineral exploration technology. Through a collaboration that spanned over three decades, we gained insight into the potential for economic uranium deposits around the world in Canada, Australia, USA, Finland, Russia, Gabon, Namibia, Botswana, South Africa, and Guyana. Kurt, his research team, postdoctoral fellows, and students developed technological innovations related to holistic basin analysis for economic mineral potential, isotopes in mineral exploration, and biogeochemical exploration, among others. In this paper, the business of mineral exploration is briefly described, and some examples of industry-academic collaboration innovations brought forward through Kurt's research are identified. Kurt was a masterful and capable knowledge broker, which is a key criterion for bringing new technologies to application—a grand, curious, credible, patient, and attentive communicator—whether talking about science, business, or life and with first ministers, senior technocrats, peers, board members, first nation peoples, exploration geologists, investors, students, citizens, or friends.

Insight Into

An Australian College of Operating Room Nurses (ACORN) submission (ACORN 2002–2008) recently stated that the specialities that suffered significantly from the transition of hospital-based nursing training to university training were the perioperative specialty, critical care and emergency. The main reason for this was that perioperative nursing was not included in the undergraduate nursing curriculum. Less than a handful of universities in Australia offer the subject as a compulsory unit. The University of Notre Dame Australia (UNDA) is one of these universities. This paper will provide an insight into the perioperative nursing care unit embedded within the Bachelor of Nursing (BN) undergraduate curriculum.

Elite video game competition provides a setting for studying how digitally connected teams handle massive amounts of information that no individual could manage on their own. This article discusses observations of the University of California, Irvine's scholarship League of Legends teams' practices and competitions from fall 2016 through spring 2017. The observations explore the nature of distributed cognition of time and temporal information in a high-pressure, competitive environment. The capacity and strategies of these teams to maintain high levels of coordination, while sitting at desktops for hours at a time, can provide insight into how other kinds of teams might learn to collaborate skillfully in networked settings.

Context: Pain in sport has been normalized to the point where athletes are expected to ignore pain and remain in the game despite the possible detrimental consequences associated with playing through pain. While rehabilitation specialists may not have an influence on an athlete’s competitive nature or the culture of risk they operate in, understanding the consequences of those factors on an athlete’s physical well-being is definitely in their area of responsibility. Objective: To explore the factors associated with the experiences of subelite athletes who play through pain in gymnastics, rowing, and speed skating. Design: The authors conducted semistructured interviews with subelite athletes, coaches, and rehabilitation specialists. They recruited coach participants through their provincial sport organization. Athletes of the recruited coaches who were recovering from a musculoskeletal injury and training for a major competition were then recruited. They also recruited rehabilitation specialists who were known to treat subelite athletes independently by e-mail. Setting: An observation session was conducted at the athlete’s training facility. Interviews were then conducted either in a room at the university or at a preferred sound-attenuated location suggested by the participant. Participants: The authors studied 5 coaches, 4 subelite athletes, and 3 rehabilitation specialists. Interventions: The authors photographed athletes during a practice shortly before an important competition, and we interviewed all the participants after that competition. Our photographs were used during the interview to stimulate discussion. Results: The participant interviews revealed 3 main themes related to playing through pain. They are: Listening to your body, Decision making, and Who decides. Conclusion: When subelite athletes, striving to be the best in their sport continue to train with the pain of an injury, performance is affected in the short-term and long-term consequences are also possible. Our study provides some insight into the contrasting forces that athletes balance as they decide to continue or to stop.

The paper aims to present an analysis of the component sizes of commercially available vehicles with electrified powertrains. The paper provides insight into how the powertrain components (an internal combustion engine, an electric motor and a battery) of mass production electrified vehicles are sized. The data of wide range of mass production electrified vehicles are collected and analyzed. Firstly, the main requirements to performance of a vehicle are described. The power values to meet the main performance requirements are calculated and compared to the real vehicle data. Based on the calculated values of the power requirements the minimum sizes of the powertrain components are derived. The paper highlights how the sizing methodologies, described in the research literature, are implemented in sizing the powertrain of the commercially available electrified vehicles.

The article offers an insight into problematic issues the advanced learners of Polish as a FL cope with in terms of grammar in speaking and writing. It opens with a brief insight into teaching literature, poetry including, in a FL classroom. What follows includes types of poems and their potential to be used in the teaching context, mainly when teaching grammar. Having presented  the scope of linguistic problems experienced by the users of Polish as a FL, the type and frequency of grammatical problems are discussed. Polish grammar-based issues the foreigners struggle with constituted the main area of the research conducted among 146 students of the Polish Language Course attending the School of Polish Language and Culture at the University of Silesia in Katowice, Poland. The findings come from oral and written assignments produced by the sample in question, and, most frequently, reflect grammatical mistakes that are persistent and difficult to eliminate from the linguistic repertoire. Given that,  ways of using poetry as a means of a “grammar refresher” are suggested. These include a few examples of activities based on poems to be used  when trying to overcome particular linguistic difficulties, together with implications for teachers raising students’ language awareness and developing reflection on language per se.

Special Meaning

<p>Law 232 of August 27, 2004 has a special meaning to the people residing in some of Puerto Rico's poorest communities. It was the result of the hard work, during a period of a year and a half, of leaders from some of these communities and my students, the students of the community development section of the Legal Aid Clinic of the University of Puerto Rico’s School of Law. The story of Law 232 can provide insight into what the role of a lawyer can be in the battle against poverty. To understand the story of this Puerto Rican law, one has to go back to August of 2002. During that month the University of Puerto Rico's School of Law Legal Aid Clinic inaugurated its community development section.</p>
