Full Text Available The results of measurements of the selected properties of the extruded potato pellets and snacks expanded in the microwave field are presented in the paper. The potato pellets with the addition of the baking soda were prepared with a single screw extruder TS-45. The snacks were obtained by pellets expansion in a conventional microwave oven. The expansion index and the hardness of the pellets and the snacks, as well as, the texture properties of the snacks were evaluated during this study. The results showed that baking soda addition reduced the potato pellet expansion during their extrusion. This was an effect of a smaller thickness of the obtained pellets. The addition of baking soda had positive influence on potato snacks expansion in microwave radiation. The higher content of the soda additive resulted in lower hardness of pellets during cutting tests. The opposite effect was observed during texture measurements of the snacks. The addition of baking soda increased hardness of the expanded snacks. Soda addition lowers crispness and fragilityof the potato snacks expanded in the microwave radiation.

2009-01-01

In 2007, the National Research Council's committee on Extending Observations and Research Results to Practical Applications recommended that NASA's Applied Science Program (ASP) directly engage with a broader community of users - not just federal agencies. Soon afterwards, scientists at the NASA Marshall Space Flight Center began discussions on a collaborative research project with EMBARQ - the World Resource Institute's Center for Sustainable Transport. The discussions initially focused on how best to utilize satellite observations and atmospheric models for assessing the impact of a proposed transportation project on land use and air quality. Discussions exposed the participants to a broad spectrum of science and policy challenges that these diverse organizations face on a routine basis. It brought into clear focus the need for an observation-modeling system that will allow a proactive approach towards development planning, and the fact that satellite systems do not always provide the spatial and temporal resolution useful for urban-scale applications, underscoring the need for earth system models to bridge this gap. Realizing the significant risk that unplanned urbanization and climate change pose to the social and functional stability of large cities, both organizations decided to expand the scope of their preliminary discussion to include water resources and agriculture. A pilot project, funded by NASA ASP, EMBARQ and Istanbul Technical University focused on quantifying the magnitude and extent of urbanization in Istanbul, and analyzed the combined effect of urbanization and projected climate change on local climate, air quality, and its consequent effects on agricultural productivity. Preliminary results show that Istanbul has undergone a significant amount of Land Use/Land Cover change over the past two decades. While some forested areas have been lost to urban-landscapes, urbanization has mostly occurred over former croplands due to the fact that in

2013-08-01

Our aim was to study the mental health consequences of Israeli adolescents' 8-day "Holocaust memorial journey" to Poland. A survey to ascertain the experience of Israeli child and adolescent psychiatrists and residents in the specialty was conducted. Participants were asked about referrals regarding the memorial journey, and to compare these cases with referrals for other potentially traumatic events, including school "sleep-out" trips. Fifty child and adolescent psychiatrists and residents participated. According to their collective experience, the adolescents' memorial journey triggered a variety of mental health problems, including psychosis, but only one case of post-traumatic stress disorder (PTSD). Judging by the number of referrals, there was a higher rate of mental health problems following the memorial journey than after the annual sleep-out school trip. Although it may seldom lead to PTSD, the Holocaust memorial journey can be a major stressor for some participating teenagers. Evaluating "high risk" adolescents prior to their planned exposure to likely stressors and conducting large, prospective studies that examine the impact of pre-planned stressors on the lives of adolescents are warranted. Providing support to all adolescents before, during and after exposure to anticipated stressors is important.

To measure levels of fine particulate matter in the rear passenger area of cars where smoking does and does not take place during typical real-life car journeys. Fine particulate matter (PM(2.5)) was used as a marker of secondhand smoke and was measured and logged every minute of each car journey undertaken by smoking and non-smoking study participants. The monitoring instrument was located at breathing zone height in the rear seating area of each car. Participants were asked to carry out their normal driving and smoking behaviours over a 3-day period. 17 subjects (14 smokers) completed a total of 104 journeys (63 smoking journeys). Journeys averaged 27 min (range 5-70 min). PM(2.5) levels averaged 85 and 7.4 μg/m(3) during smoking and non-smoking car journeys, respectively. During smoking journeys, peak PM(2.5) concentrations averaged 385 μg/m(3), with one journey measuring over 880 μg/m(3). PM(2.5) concentrations were strongly linked to rate of smoking (cigarettes per minute). Use of forced ventilation and opening of car windows were very common during smoking journeys, but PM(2.5) concentrations were still found to exceed WHO indoor air quality guidance (25 μg/m(3)) at some point in the measurement period during all smoking journeys. PM(2.5) concentrations in cars where smoking takes place are high and greatly exceed international indoor air quality guidance values. Children exposed to these levels of fine particulate are likely to suffer ill-health effects. There are increasing numbers of countries legislating against smoking in cars and such measures may be appropriate to prevent the exposure of children to these high levels of secondhand smoke.

Hawaii will celebrate its tenth anniversary of the flagship Journey through the Universe program that began in 2004. The Gemini-led initiative has engaged hundreds of astronomers and astronomy educators that have visited over 2,700 classrooms, visiting over 60,000 students over the course of the last nine years. The scientists have brought excitement and inspiration about the life-long possibilities available in science, technology and mathematics to our students. The Journey program nurtures our students' innate curiosity, offers workshops for hundreds of teachers in Science, Technology, Engineering, and Math (STEM) education, and provides an opportunity for our community members to visit the classrooms alongside our astronomers. This ten-day annual event also includes Family Science Events that are enjoyed by thousands. For the 2013 program, our governor, Neil Abercrombie, inquired about the program and its enormous impact on Hawaii's students. Governor Abercrombie actively participated by visiting classrooms at different schools and attending our chamber of commerce appreciation event. This paper will share how the Journey program came to be and what is anticipated for the tenth anniversary. Journey through the Universe is a model outreach initiative that could be duplicated in other locations.

Virtual Reality for Prototyping Service Journeys

Directory of Open Access Journals (Sweden)

Costas Boletsis

2018-04-01

Full Text Available The use of virtual elements for developing new service prototyping environments and more realistic simulations has been suggested as a way to optimise the service prototyping process. This work examines the application of virtual reality (VR in prototyping service journeys and it hypothesises that VR can recreate service journeys in a highly immersive, agile, and inexpensive manner, thus allowing users to have a representative service experience and enabling service designers to extract high-quality user feedback. To that end, a new service prototyping method, called VR service walkthrough, is presented and evaluated through an empirical comparative study. A VR service walkthrough is a virtual simulation of a service journey, representing how the service unfolds over space and time. A comparative study between the VR service walkthrough method and an adapted service walkthrough method evaluates the application of both methods using a location-based audio tour guide service as a case study. Two user groups (each with 21 users were used to evaluate both methods based on two factors: the user experience they offered and the subjective meaningfulness and quality of feedback they produced. Results show that the VR service walkthrough method gave a performance similar to that of the service walkthrough method. It was also able to communicate the service concept in an immersive way and foster constructive feedback.

Multi-dimensional knowledge translation: enabling health informatics capacity audits using patient journey models.

Science.gov (United States)

Catley, Christina; McGregor, Carolyn; Percival, Jennifer; Curry, Joanne; James, Andrew

2008-01-01

This paper presents a multi-dimensional approach to knowledge translation, enabling results obtained from a survey evaluating the uptake of Information Technology within Neonatal Intensive Care Units to be translated into knowledge, in the form of health informatics capacity audits. Survey data, having multiple roles, patient care scenarios, levels, and hospitals, is translated using a structured data modeling approach, into patient journey models. The data model is defined such that users can develop queries to generate patient journey models based on a pre-defined Patient Journey Model architecture (PaJMa). PaJMa models are then analyzed to build capacity audits. Capacity audits offer a sophisticated view of health informatics usage, providing not only details of what IT solutions a hospital utilizes, but also answering the questions: when, how and why, by determining when the IT solutions are integrated into the patient journey, how they support the patient information flow, and why they improve the patient journey.

Journeys through antigravity?

Science.gov (United States)

Carrasco, John Joseph M.; Chemissany, Wissam; Kallosh, Renata

2014-01-01

A possibility of journeys through antigravity has recently been proposed, with the suggestion that Weyl-invariant extension of scalars coupled to Einstein gravity allows for an unambiguous classical evolution through cosmological singularities in anisotropic spacetimes. We compute the Weyl invariant curvature squared and find that it blows up for the proposed anisotropic solution both at the Big Crunch as well as at the Big Bang. Therefore the cosmological singularities are not resolved by uplifting Einstein theory to a Weyl invariant model.

Community and inquiry: journey of a science teacher

Science.gov (United States)

Goldberg, Jennifer; Welsh, Kate Muir

2009-09-01

In this case study, we examine a teacher's journey, including reflections on teaching science, everyday classroom interaction, and their intertwined relationship. The teacher's reflections include an awareness of being "a White middle-class born and raised teacher teaching other peoples' children." This awareness was enacted in the science classroom and emerges through approaches to inquiry . Our interest in Ms. Cook's journey grew out of discussions, including both informal and semi-structured interviews, in two research projects over a three-year period. Our interest was further piqued as we analyzed videotaped classroom interaction during science lessons and discovered connections between Ms. Cook's reflections and classroom interaction. In this article, we illustrate ways that her journey emerges as a conscientization. This, at least in part, shapes classroom interaction, which then again shapes her conscientization in a recursive, dynamic relationship. We examine her reflections on her "hegemonic (cultural and socio-economic) practices" and consider how these reflections help her reconsider such practices through analysis of classroom interaction. Analyses lead us to considering the importance of inquiry within this classroom community.

Remembering to learn: independent place and journey coding mechanisms contribute to memory transfer.

Science.gov (United States)

Bahar, Amir S; Shapiro, Matthew L

2012-02-08

The neural mechanisms that integrate new episodes with established memories are unknown. When rats explore an environment, CA1 cells fire in place fields that indicate locations. In goal-directed spatial memory tasks, some place fields differentiate behavioral histories ("journey-dependent" place fields) while others do not ("journey-independent" place fields). To investigate how these signals inform learning and memory for new and familiar episodes, we recorded CA1 and CA3 activity in rats trained to perform a "standard" spatial memory task in a plus maze and in two new task variants. A "switch" task exchanged the start and goal locations in the same environment; an "altered environment" task contained unfamiliar local and distal cues. In the switch task, performance was mildly impaired, new firing maps were stable, but the proportion and stability of journey-dependent place fields declined. In the altered environment, overall performance was strongly impaired, new firing maps were unstable, and stable proportions of journey-dependent place fields were maintained. In both tasks, memory errors were accompanied by a decline in journey codes. The different dynamics of place and journey coding suggest that they reflect separate mechanisms and contribute to distinct memory computations. Stable place fields may represent familiar relationships among environmental features that are required for consistent memory performance. Journey-dependent activity may correspond with goal-directed behavioral sequences that reflect expectancies that generalize across environments. The complementary signals could help link current events with established memories, so that familiarity with either a behavioral strategy or an environment can inform goal-directed learning.

Full Text Available In Jože Hradil’s Faceless Pictures [Slike brez obrazov] the characters go astray or get into the attraction of adventures and set off for a journey. The spiritual and identity shifts can be interpreted along these eternal human desires as well. A patchwork of remembering and forgetting, the internal journeys of identity preservation, spontaneous or forced assimilation, tolerance and all kinds of politics-induced human deformations are depicted in the novel. The text traces the roles of the journey defined by Jean Chevalier and Alain Gheerbrant such as the search for justice, peace, immortality and finding the spiritual center. This study examines how the concrete physical journey changes into an internal road determining the evolution of personality.

Long Journey Travel to Tourist Destination: A Review Paper

Directory of Open Access Journals (Sweden)

Shahrin Norkamaliah

2014-01-01

Full Text Available Tourists are now more open in selecting tourist destination. The number of holiday trips were growing rapidly. There were various promotions available to attract tourists to travel either within or outside the country. Travel distance is not an obstacle for tourists to travel, regardless of local and foreign destination. This study will be conducted to identify the motivation of long journey travel that involves push and pull factors. The long journey involves distance, cost and the type of transportation used to get to the destination. For this purpose a comprehensive review and discussion on previous sources which involved a variety of secondary data sources will be used to meet every need of the study objectives. The finding showed that the travel distance was dependent on the motivation for tourists to travel and the type of transport they want to use. Mode of transport used has advantages and disadvantages for long journey travel depending on traveller choice.

Flight range, fuel load and the impact of climate change on the journeys of migrant birds

Science.gov (United States)

Sheard, Catherine; Butchart, Stuart H. M.

2018-01-01

Climate change is predicted to increase migration distances for many migratory species, but the physiological and temporal implications of longer migratory journeys have not been explored. Here, we combine information about species' flight range potential and migratory refuelling requirements to simulate the number of stopovers required and the duration of current migratory journeys for 77 bird species breeding in Europe. Using tracking data, we show that our estimates accord with recorded journey times and stopovers for most species. We then combine projections of altered migratory distances under climate change with models of avian flight to predict future migratory journeys. We find that 37% of migratory journeys undertaken by long-distance migrants will necessitate an additional stopover in future. These greater distances and the increased number of stops will substantially increase overall journey durations of many long-distance migratory species, a factor not currently considered in climate impact studies.

A journey with Fred Hoyle

CERN Document Server

Wickramasinghe, Chandra

2013-01-01

This is the story of the author's unique scientific journey with one of the most remarkable men of 20th century science. The journey begins in Sri Lanka, the author's native country, with his childhood acquaintance with Fred Hoyle's writings. The action then moves to Cambridge, where the famous Hoyle–Wickramasinghe collaborations begin. A research programme which was started in 1962 on the carbonaceous nature of interstellar dust leads, over the next two decades, to developments that are continued in both Cambridge and Cardiff. These developments prompt Hoyle and the author to postulate the organic theory of cosmic dust (which is now generally accepted), and then to challenge one of the most cherished paradigms of contemporary science — the theory that life originated on Earth in a warm primordial soup.Two new chapters plus revisions to the other chapters bring the book up to date and thus make it more relevant, just as recent findings mesh with many of the ideas that had their origin in the first edition. ...

Goethe in the Hall and His Journeys in Printed Rome

Directory of Open Access Journals (Sweden)

Victor Plahte Tschudi

2015-12-01

Full Text Available The article focuses on graphic reproductions in Johann Wolfgang von Goethe’s 'Italian Journey'. This travel account gives a clear sense of how important prints were as part of Goethe’s education and preparation for the encounter with classical Roman monuments. As the text itself was edited and rewritten thirty to forty years after the journey itself, however, prints also became crucial in the attempt to remember that journey. In other words, the author of the 'Journey', in contrast to the youthful traveler, no longer sees engravings of Rome, but Rome through engravings. The discussion takes as a point of departure Goethe’s vast collection of prints, still kept in Weimar. Measured up against the references in the travel journal, prints not only reflected his impression of monuments, but also structured those impressions, as the elderly man looks back and reassembles his memories to make an official account of his life. However, it is too easy to ascribe this reliance on prints to a fading memory — on the contrary. As he grows into old age, Goethe’s idea of graphic reproduction evolves in parallel with his increasingly refined theories of nature. His growing preference for prints depicted as ruins reflects the aging author’s own sense of change and transformation.

"The Matrix" has been a huge commercial and critical success and has spawned a series of books and essays exploring the philosophical and religious themes in the story. The authors propose is that "The Matrix" can be interpreted as an allegory for an individual's journey into spiritual and mental health, achieved by overcoming one's intrapsychic conflicts with the help of psychodynamic psychotherapy or psychoanalysis. Neo's story parallels the journey undertaken by the individual who chooses to enter psychotherapy and illustrates several themes of analytic psychotherapy, its benefits, and liabilities. The movie may therefore serve as a teaching tool for psychiatric residents about the goals, functions, and intricacies of psychodynamic psychotherapy.

PREFACE: A Stellar Journey A Stellar Journey

Asplund, M.

2008-10-01

The conference A Stellar Journey was held in Uppsala, Sweden, 23 27June 2008, in honour of Professor Bengt Gustafsson's 65th birthday. The choice of Uppsala as the location for this event was obvious given Bengt's long-standing association with the city stemming back to his school days. With the exception of a two-year postdoc stint in Copenhagen, five years as professor at Stockholm University and two years as director of the Sigtuna foundation, Bengt has forged his illustrious professional career at Uppsala University. The symposium venue was Museum Gustavianum, once the main building of the oldest university in Scandinavia. The title of the symposium is a paraphrasing of Bengt's popular astronomy book Kosmisk Resa (in English: Cosmic Journey) written in the early eighties. I think this aptly symbolizes his career that has been an astronomical voyage from near to far, from the distant past to the present. The original book title was modified slightly to reflect that most of his work to date has dealt with stars in one way or another. In addition it also gives credit to Bengt's important role as a guiding light for a very large number of students, colleagues and collaborators, indeed for several generations of astronomers. For me personally, the book Kosmisk Resa bears particular significance as it has shaped my life rather profoundly. Although I had already decided to become an astronomer, when I first read the book as a 14-year-old I made up my mind then and there that I would study under Bengt Gustafsson and work on stars. Indeed I have remained true to this somewhat audacious resolution. I suspect that a great number of us have similar stories how Bengt has had a major influence on our lives, whether on the professional or personal level. Perhaps Bengt's most outstanding characteristic is his enthralling enthusiasm. This is equally true whether he is pondering some scientific conundrum, supervising students or performing in front of an audience, be it an

Climate change is predicted to increase migration distances for many migratory species, but the physiological and temporal implications of longer migratory journeys have not been explored. Here, we combine information about species' flight range potential and migratory refuelling requirements to simulate the number of stopovers required and the duration of current migratory journeys for 77 bird species breeding in Europe. Using tracking data, we show that our estimates accord with recorded journey times and stopovers for most species. We then combine projections of altered migratory distances under climate change with models of avian flight to predict future migratory journeys. We find that 37% of migratory journeys undertaken by long-distance migrants will necessitate an additional stopover in future. These greater distances and the increased number of stops will substantially increase overall journey durations of many long-distance migratory species, a factor not currently considered in climate impact studies. © 2018 The Authors.

Full Text Available This study was conducted to examine the effects on weight loss (WL, residual yolk (RY utilization and serum biochemical parameters of transport distance (TD in newly hatched broiler chicks. Just after hatching, 200 Ross 308 broiler chicks were traveled over 1000 km. At hatchery and after 200, 400, 600, 800 and 1000 km journey, a random sample of 20 birds were killed for blood collection, WL and yolk weight assessment. Live weight decreased linearly by 0.42 and 0.48 g per 100 km of journey in males and female chicks, respectively. Yolk sac residual utilized by 0.071 and 0.069 g per 100 km of travel in males and females chicks, respectively, over journey distances up to 800 km. Extended journey from 800 to 1000 km caused a great decline of 0.51 and 0.58 g per 100 km in yolk weight in male and female chicks, respectively. Serum Ca concentration reduced in TDs up to 400 km, then increased for longer journeys (P<0.05. Over 1000 km journey, serum GLU level of 196.24 mg/dL at hatchery was decreased to 117.31 mg/dL at the end of journey. Serum urea, uric acid and cholesterol concentrations were increased with the extended TDs (P<0.05. In conclusion increasing transportation distance causes intensified physiological stress in broiler chicks with varying effect on different stress indicators. Stress indicators in newly hatched chicks in transit may differ from those proposed for replaced chicks and the broiler chicken at later ages.

Hard material technologies were surveyed to establish the hard electronic technology which offers superior characteristics under hard operational or environmental conditions as compared with conventional Si devices. The following technologies were separately surveyed: (1) The device and integration technologies of wide gap hard semiconductors such as SiC, diamond and nitride, (2) The technology of hard semiconductor devices for vacuum micro- electronics technology, and (3) The technology of hard new material devices for oxides. The formation technology of oxide thin films made remarkable progress after discovery of oxide superconductor materials, resulting in development of an atomic layer growth method and mist deposition method. This leading research is expected to solve such issues difficult to be easily realized by current Si technology as high-power, high-frequency and low-loss devices in power electronics, high temperature-proof and radiation-proof devices in ultimate electronics, and high-speed and dense- integrated devices in information electronics. 432 refs., 136 figs., 15 tabs.

A journey of leadership: from bedside nurse to chief executive officer.

Science.gov (United States)

Comack, Margret Tannis

2012-01-01

Understanding leadership from the inside out was a journey that spanned a 40-year career in health care. This article describes an individual's journey of becoming an effective executive leader using the LEADS in a caring environment--capabilities framework. This framework was recently developed in Canada and is now used broadly to understand the complexity and depth of health care leadership skills and challenges. The author utilizes the framework to explore leadership skill development from a personal perspective to a broader system transformation level. Challenges and successes along this journey are included to highlight the manner in which leadership evolves with experience, time, and determination. A retrospective view of a successful career in health care provides the model for others to consider a similar career path using a theoretical base and a thoughtful process of personal development.

estimate a mean ‘reliability ratio’ (ratio of the value of standard deviation of journey time to the value of scheduled journey time) of 2.07, against a median of 0.85. The properties of the distribution of the reliability ratio suggest a predominant behaviour of aversion to journey time risk.......Within the broad area of probabilistic modelling of individual discrete choice, we develop three strands of discussion. First, we outline a theoretical framework for the modelling of individual discrete choice under risk, distinguishing between three specific sources of randomness; in preference...... orderings, in outcomes, and in attribute tastes.

Coratza, Paola; Panizza, Mario

2015-04-01

Over 220 years ago Johann Wolfgang von Goethe undertook a nearly two-years long and fascinating journey to Italy, a destination dreamed for a long time by the great German writer. During his journey from Alps to Sicily Goethe reflects on landscape, geology, morphology of "Il Bel Paese", sometimes providing detailed descriptions and acute observations concerning the great and enduring laws by which the earth and all within it are governed. He was an observer, with the eye of the geologist and landscape painter, as he himself stated, and therefore he had a 360 degree focus on all parts of the territory. From the Brenner Pass to Sicily, Goethe reflects on landscape, contrasting morphologies, the genesis of territories, providing detailed descriptions useful for reconstructing the conditions of the territory and crops of the late 18th century. His diary is a description of the impressions he received from the country and its people, mingled with reflections upon art, science and literature. Goethe studied mineralogical and geological phenomena and drew up notes on the life of the people, the climate and the plants. On various scientific occasions and, in particular, within the framework of the Italian Association "Geologia & Turismo", of the Working Group "Geomorphosites" of the International Association of Geomorphologists and the International Year of Planet Earth, the opportunity to re-examine Goethe's travels in Italy from a geological viewpoint was recognised. In the present paper an attempt was made to reproduce the geotourism itinerary ante litteram of the writer to Italy, one of the most important tourist destination worldwide, thanks to its rich cultural and natural heritage and the outstanding aesthetic qualities of the complex natural landscape. This project was essentially conceived with a twofold purpose. First of all, an attempt was made to reproduce the journey of a great writer, as an example of description of landscape perceived and described as

The mythic structure in the black dome of the Haftpeikar: Study of Hero's journey in the first dome

2016-12-01

Full Text Available Abstract In this paper the Vogler Hero's journey is used for analyzing the mythic structures and hero's journey of the first dome of the Haftpeikar. Vogler Released his founds in the Writer's Journey book. This book that is really dependent on Campbell's Single Myth Theory is a practical guidance for script writing and review of that. The levels of the hero's journey in his book are include: The normal world, invitation to the story, reject the invitation, visit the mentor, passing the first gate, the exams, the allies, the enemies, qualifying to the deepest cave, trial, the reward, the road back, resurrection, return with the elixir.  In this paper, at first the properties of each level of the hero's journey theory are matching with the journey's levels in the black dome story. After that seven useful archetypes including hero, mentor, threshold guardian, herald, shape shifter, the shadow and trickster, are determined in the text.  Black dome has several journeys' cycles. Journey's that are seen in this dome are: (Bahram's journey: A part of the internal journey of Bahram in black dome. (The king's maid journey: Internal journey of the king's maid that wears black clothes after hearing the story. (King of black clothes' journey: The king's journey to the Madhooshan city for exploring the mystery of the black alien. (The reader's journey: This internal journey belongs to the readers of the first dome that learn their lessons through traveling to the character's world. (Nezami's journey: The Nezami's internal journey with composing the text. Checking the reader's journey and black dome's composer is out of this text. While the first and second journey just saying some parts, the black king has completer levels and for affecting on the other journeys is the most important story of the first dome. Therefore at first we check the black king story and we explain the other journeys.  The goal of this paper in addition to the usage of the vogler

Full Text Available “Science on the air” is an enjoyable and extremely well researched account of the origins of science programming in north American radio. From 1923 to the mid-50s, LaFollette takes us in a journey through the life and programs of many scientists, journalists and storytellers who chosed radio as a medium for science communication. A journey who allow the reader to visit many success, but also many incomprehension and missed opportunities, mainly by scientific institutions, who often failed to understand the potential of radio as a tool for science communication. It is a fully enjoyable journey, that leave the reader with an appetite to know how the US situation relates to other wonderful experiences around the world in the same years, and how those pioneer experiences influenced today's landscape.

The shift to early palliative care: a typology of illness journeys and the role of nursing.

Wittenberg-Lyles, Elaine; Goldsmith, Joy; Ragan, Sandra

2011-06-01

For the current study, clinical observations of communication between patients, families, and clinicians during chronic, serious, or terminal illness in a cancer care trajectory were examined for patterns and trends. Five communication characteristics were concluded, which informed a typology of illness journeys experienced by patients with cancer and their families. The isolated journey characterizes an illness path in which communication about terminal prognosis and end-of-life care options are not present; communication is restricted by a curative-only approach to diagnosis as well as the structure of medical care. The rescued journey signifies a transition between curative care (hospital narrative) to noncurative care (hospice narrative), challenging patients and their families with an awareness of dying. The rescued journey allows communication about prognosis and care options, establishes productive experiences through open awareness, and affords patients and families opportunities to experience end-of-life care preferences. Finally, palliative care prior to hospice provides patients and families with an illness journey more readily characterized by open awareness and community, which facilitates a comforted journey. Nurses play a pivotal role in communicating about disease progression and plans of care. The typology presented can inform a structured communication curriculum for nurses and assist in the implementation of early palliative care.

Scientific discoveries and technological advancements are inseparable but not always take place in a coherent chronological manner. In the next, we will provide a seemingly unconnected and serendipitous series of scientific facts that, in the whole, converged to unveil DNA and its duplication. We will not cover here the many and fundamental contributions from microbial genetics and in vitro biochemistry. Rather, in this journey, we will emphasize the interplay between microscopy development culminating on super resolution fluorescence microscopy (i.e., nanoscopy) and digital image analysis and its impact on our understanding of DNA duplication. We will interlace the journey with landmark concepts and experiments that have brought the cellular DNA replication field to its present state.

Patients as story-tellers of healthcare journeys.

Science.gov (United States)

Lamprell, Klay; Braithwaite, Jeffrey

2016-09-01

There are gaps in our comprehension of patients' subjective experiences as they engage with and transit through the healthcare environments implicated in their treatment trajectories. Patients' stories, unlike patient experience data gathered in questionnaires and surveys, express the deeply personal, narrative nature of the journeys that patients take, creating opportunities for qualitative healthcare research. Yet narrative capabilities and propensities vary with individuals, and are affected by the stresses of illness and treatment. This article extends the growing interest in narrative competence training for both practitioners and patients with the investigation of a story-telling model that could facilitate patients to narrate their experiences of healthcare systems. This model is derived from the literary arts. In fiction and autobiography, the journey arc of the central character is often one in which he or she is compelled to leave the comfort of everyday life and face a series of extraordinary events involving challenge and change which forces the character towards practical, intellectual, psychological and philosophical adjustments that define, by the end of the story, the character's 'new normal'. This pattern is known as the 'hero journey'. Its parallels with patients' experiences of healthcare and the way people narrate their stories of illness have long been recognised. We present here a new idea for applying this model as a narrative structure by which patients may construct their stories about being in and moving through the healthcare system.

The WORKS framework supported Keeley and Sally to collaboratively develop a successful employment pathway. Strategies, including attention to Keeley's view of her capabilities and aspirations, volunteer placements, support of peers, employer engagement and planning for sustainable employment, assisted Keeley to establish her chosen career. Keeley's journey highlights the leadership role that mental health services can assume by providing paid work for people with experience of mental health difficulties.

The chondrocytic journey in endochondral bone growth and skeletal dysplasia.

Science.gov (United States)

Yeung Tsang, Kwok; Wa Tsang, Shun; Chan, Danny; Cheah, Kathryn S E

2014-03-01

The endochondral bones of the skeleton develop from a cartilage template and grow via a process involving a cascade of chondrocyte differentiation steps culminating in formation of a growth plate and the replacement of cartilage by bone. This process of endochondral ossification, driven by the generation of chondrocytes and their subsequent proliferation, differentiation, and production of extracellular matrix constitute a journey, deviation from which inevitably disrupts bone growth and development, and is the basis of human skeletal dysplasias with a wide range of phenotypic severity, from perinatal lethality to progressively deforming. This highly coordinated journey of chondrocyte specification and fate determination is controlled by a myriad of intrinsic and extrinsic factors. SOX9 is the master transcription factor that, in concert with varying partners along the way, directs the different phases of the journey from mesenchymal condensation, chondrogenesis, differentiation, proliferation, and maturation. Extracellular signals, including bone morphogenetic proteins, wingless-related MMTV integration site (WNT), fibroblast growth factor, Indian hedgehog, and parathyroid hormone-related peptide, are all indispensable for growth plate chondrocytes to align and organize into the appropriate columnar architecture and controls their maturation and transition to hypertrophy. Chondrocyte hypertrophy, marked by dramatic volume increase in phases, is controlled by transcription factors SOX9, Runt-related transcription factor, and FOXA2. Hypertrophic chondrocytes mediate the cartilage to bone transition and concomitantly face a live-or-die situation, a subject of much debate. We review recent insights into the coordination of the phases of the chondrocyte journey, and highlight the need for a systems level understanding of the regulatory networks that will facilitate the development of therapeutic approaches for skeletal dysplasia.

Unprecedented radiation hardness and environment robustness are required in the new generation of high energy density physics (HEDP) experiments and deep space exploration. National Ignition Facility (NIF) break-even shots will have a neutron yield of 10 15 or higher. The Europa Jupiter System Mission (EJSM) mission instruments will be irradiated with a total fluence of 10 12 protons/cm 2 during the space journey. In addition, large temperature variations and mechanical shocks are expected in these applications under extreme conditions. Hefty radiation and thermal shields are required for Si and GaAs based electronics and optoelectronics devices. However, for direct illumination and imaging applications, shielding is not a viable option. It is an urgent task to search for new semiconductor technologies and to develop radiation hard and environmentally robust optoelectronic devices. We will report on our latest systematic experimental studies on radiation hardness and space qualifications of AlGaN optoelectronic devices: Deep UV Light Emitting Diodes (DUV LEDs) and solarblind UV Photodiodes (PDs). For custom designed AlGaN DUV LEDs with a central emission wavelength of 255 nm, we have demonstrated its extreme radiation hardness up to 2 x 10 12 protons/cm 2 with 63.9 MeV proton beams. We have demonstrated an operation lifetime of over 26,000 hours in a nitrogen rich environment, and 23,000 hours of operation in vacuum without significant power drop and spectral shift. The DUV LEDs with multiple packaging styles have passed stringent space qualifications with 14 g random vibrations, and 21 cycles of 100K temperature cycles. The driving voltage, current, emission spectra and optical power (V-I-P) operation characteristics exhibited no significant changes after the space environmental tests. The DUV LEDs will be used for photoelectric charge management in space flights. For custom designed AlGaN UV photodiodes with a central response wavelength of 255 nm, we have

Structural properties of hard disks in a narrow tube

International Nuclear Information System (INIS)

Varga, S; Gurin, P; Balló, G

2011-01-01

Positional ordering of a two-dimensional fluid of hard disks is examined in tubes so narrow that only nearest neighbor interactions take place. Using the exact transfer-matrix method the transverse and longitudinal pressure components and the correlation function are determined numerically. Fluid–solid phase transition does not occur even in the widest tube, where the method just loses its exactness, but the appearance of a dramatic change in the equation of state and the longitudinal correlation function shows that the system undergoes a structural change from a fluid to a solid-like order. The pressure components show that the collisions are dominantly longitudinal at low densities, while they are transverse in the vicinity of the close packing density. The transverse correlation function shows that the size of solid-like domains grows exponentially with increasing pressure and the correlation length diverges at close packing. It is possible to find an analytically solvable model by expanding the contact distance up to first order. The approximate model, which corresponds to a system of hard parallel rhombuses, behaves very similarly to the system of hard disks

Exploring the requirements for multimodal interaction for mobile devices in an end-to-end journey context.

Science.gov (United States)

Krehl, Claudia; Sharples, Sarah

2012-01-01

The paper investigates the requirements for multimodal interaction on mobile devices in an end-to-end journey context. Traditional interfaces are deemed cumbersome and inefficient for exchanging information with the user. Multimodal interaction provides a different user-centred approach allowing for more natural and intuitive interaction between humans and computers. It is especially suitable for mobile interaction as it can overcome additional constraints including small screens, awkward keypads, and continuously changing settings - an inherent property of mobility. This paper is based on end-to-end journeys where users encounter several contexts during their journeys. Interviews and focus groups explore the requirements for multimodal interaction design for mobile devices by examining journey stages and identifying the users' information needs and sources. Findings suggest that multimodal communication is crucial when users multitask. Choosing suitable modalities depend on user context, characteristics and tasks.

The Journey to Become a Health Literate Organization: A Snapshot of Health System Improvement

Science.gov (United States)

BRACH, Cindy

2017-01-01

A health literate health care organization is one that makes it easy for people to navigate, understand, and use information and services to take care of their health. This chapter explores the journey that a growing number of organizations are taking to become health literate. Health literacy improvement has increasingly been viewed as a systems issue, one that moves beyond siloed efforts by recognizing that action is required on multiple levels. To help operationalize the shift to a systems perspective, members of the National Academies Roundtable on Health Literacy defined ten attributes of health literate health care organizations. External factors, such as payment reform in the U.S., have buoyed health literacy as an organizational priority. Health care organizations often begin their journey to become health literate by conducting health literacy organizational assessments, focusing on written and spoken communication, and addressing difficulties in navigating facilities and complex systems. As organizations’ efforts mature, health literacy quality improvement efforts give way to transformational activities. These include: the highest levels of the organization embracing health literacy, making strategic plans for initiating and spreading health literate practices, establishing a health literacy workforce and supporting structures, raising health literacy awareness and training staff system-wide, expanding patient and family input, establishing policies, leveraging information technology, monitoring policy compliance, addressing population health, and shifting the culture of the organization.

A health literate health care organization is one that makes it easy for people to navigate, understand, and use information and services to take care of their health. This chapter explores the journey that a growing number of organizations are taking to become health literate. Health literacy improvement has increasingly been viewed as a systems issue, one that moves beyond siloed efforts by recognizing that action is required on multiple levels. To help operationalize the shift to a systems perspective, members of the U.S. National Academies of Sciences, Engineering, Medicine Roundtable on Health Literacy defined ten attributes of health literate health care organizations. External factors, such as payment reform in the U.S., have buoyed health literacy as an organizational priority. Health care organizations often begin their journey to become health literate by conducting health literacy organizational assessments, focusing on written and spoken communication, and addressing difficulties in navigating facilities and complex systems. As organizations' efforts mature, health literacy quality improvement efforts give way to transformational activities. These include: the highest levels of the organization embracing health literacy, making strategic plans for initiating and spreading health literate practices, establishing a health literacy workforce and supporting structures, raising health literacy awareness and training staff system-wide, expanding patient and family input, establishing policies, leveraging information technology, monitoring policy compliance, addressing population health, and shifting the culture of the organization. The penultimate section of this chapter highlights the experiences of three organizations that have explicitly set a goal to become health literate: Carolinas Healthcare System (CHS), Intermountain Healthcare, and Northwell Health. These organizations are pioneers that approached health literacy in a systematic fashion, each

Cleft palate repair with the use of osmotic expanders: a preliminary report.

Science.gov (United States)

Kobus, Kazimierz F

2007-01-01

A new method of cleft palate repair by expansion of tissue by means of osmotic expanders implanted in the first stage of treatment is described. Self-expanding expanders manufactured by OSMED (Ilmenau, Germany) were implanted under the mucoperiosteal layer of the hard palate, on purpose to generate more tissue and provide facility for palate repair performed 24-48h later. Nineteen children aged from 2 to 3 years were operated from January 2004 to 15 April 2005. In clefts10mm, cleft palate repair was more difficult and the outcomes were less favourable. Despite more generous dissection of the neurovascular bundles and other adjunctive measures such as mucosal V-Y plasty [Bardach J, Salyer K. Surgical techniques in cleft lip and palate. Chicago, London: Year Book Medical Publishers, Inc.; 1987.] and suturing of the mucosal grafts at the border of the hard and soft palate, seven 2-4mm fistulae were noted, however. Concluding, in spite of some shortcomings and unacceptable rate of fistula in wide clefts, the above-presented method seems to be an attractive concept. Despite some technical problems related mostly to still tested optimal filling phase, tissue expansion makes palate repair easier, probably without relaxing incisions and bone denudation. Consequently, some adverse effects on facial growth may be reduced. So far, there is no evidence for it, however, and since this is a preliminary report, there is a need for longer observations and larger material.

To understand the journey of advanced prostate cancer patients for supporting development of an innovative patient journey browser. Prostate cancer is one of the common cancers in Australia. Due to the chronic nature of the disease, it is important to have effective disease management strategy and care model. Multi-disciplinary care is a well-proven approach for chronic disease management. The Multi-disciplinary team (MDT) can function more effectively if all the required information is available for the clinical decision support. The development of innovative technology relies on an accurate understanding of the advanced prostate cancer patient's journey over a prolonged period. This need arises from the fact that advanced prostate cancer patients may follow various treatment paths and change their care providers. As a result of this, it is difficult to understand the actual sources of patient's clinical records and their treatment patterns. The aim of the research is to understand variable sources of clinical records, treatment patterns, alternative therapies, over the counter (OTC) medications of advanced prostate cancer patients. This study provides better and holistic understanding of advanced prostate cancer journey. The study was conducted through an on-line survey developed to seek and analyse the responses from the participants. The on-line questionnaire was carefully developed through consultations with the clinical researchers at the Australian Prostate Cancer Research Centre-Queensland, prostate cancer support group representatives and health informaticians at the Australian E-Health Research Centre. The non-identifying questionnaire was distributed to the patients through prostate cancer support groups in Queensland, Australia. The pilot study was carried out between August 2010 and December 2010. The research made important observations about the advanced prostate cancer journey. It showed that General Practitioner (GP) was the common source of

REMEMBERING TO LEARN: INDEPENDENT PLACE AND JOURNEY CODING MECHANISMS CONTRIBUTE TO MEMORY TRANSFER

OpenAIRE

The neural mechanisms that integrate new episodes with established memories are unknown. When rats explore an environment, CA1 cells fire in place fields that indicate locations. In goal-directed spatial memory tasks, some place fields differentiate behavioral histories (journey-dependent place fields) while others do not (journey-independent place fields). To investigate how these signals inform learning and memory for new and familiar episodes, we recorded CA1 and CA3 activity in rats train...

"THE LANGUAGE OF THE HIGHEST TRUTH...": PUSHKIN'S ATTITUDE TO THE GOSPEL IN HIS "JOURNEY TO ARZRUM"

Directory of Open Access Journals (Sweden)

Irina Leonidovna Bagration-Mukhraneli

2013-11-01

Full Text Available The article deals with the Christian code of Alexander Pushkin’s Journey to Arzrum, which is a style forming factor for the whole story, featuring a large thematic diversity. The genre of this book is similar to Old Russian pilgrimage stories. It includes an ethnographic sketch, a battle, Oriental and situational impressions of moving in space. All these are balanced with the biblical names and allusions, as well as the existential experience of the sacred. According to Pushkin, the Gospel is the foundation for real politics and an effective means of annexation of the Caucasus to the Russian Empire. Journey to Arzrum had an impact on the image of the war created by Leo Tolstoy in his War and Peace, as well as on the creation of such pilgrimage stories of the 20th century as A Journey to Armenia by Osip Mandelshtam and A Journey to Mount Athos by Boris Zaytsev.

We studied the metabolic changes that took place in the crew of the Hesperides vessel in their 2001-2002 Antarctic journey, comparing two periods differing in diet and physical activity. Lipid profile, vitamin and hormone levels were analyzed in 17 subjects who completed the study in its two phases. In phase I the participants spent 47 days sailing with hard work and rough seas, and the diet was rich in fat and poor in fresh foods. In this phase, glucose decreased and HDL-cholesterol, apo-AI, and TSH increased. Plasma retinol and alpha-tocopherol levels remained stable, gamma-tocopherol, alpha-carotene and beta-carotene significantly decreased, and lycopene significantly increased. Phase II lasted 49 days including a 7-day long stop in port. This meant that a more varied diet was available and fresh foods were present in the hold. There was also less extreme physical activity. The metabolic pattern changed direction, glucose rose, HDL-cholesterol and apo-AI decreased and the levels of the vitamins that dropped in phase I started to increase. Lycopene significantly decreased. Contrary to popular beliefs about navigation at extreme latitudes, the metabolic changes described may be explained by the intense physical activity in a cold environment and a high-fat diet poor in fresh products.

Revisiting the definition of local hardness and hardness kernel.

Science.gov (United States)

Polanco-Ramírez, Carlos A; Franco-Pérez, Marco; Carmona-Espíndola, Javier; Gázquez, José L; Ayers, Paul W

2017-05-17

An analysis of the hardness kernel and local hardness is performed to propose new definitions for these quantities that follow a similar pattern to the one that characterizes the quantities associated with softness, that is, we have derived new definitions for which the integral of the hardness kernel over the whole space of one of the variables leads to local hardness, and the integral of local hardness over the whole space leads to global hardness. A basic aspect of the present approach is that global hardness keeps its identity as the second derivative of energy with respect to the number of electrons. Local hardness thus obtained depends on the first and second derivatives of energy and electron density with respect to the number of electrons. When these derivatives are approximated by a smooth quadratic interpolation of energy, the expression for local hardness reduces to the one intuitively proposed by Meneses, Tiznado, Contreras and Fuentealba. However, when one combines the first directional derivatives with smooth second derivatives one finds additional terms that allow one to differentiate local hardness for electrophilic attack from the one for nucleophilic attack. Numerical results related to electrophilic attacks on substituted pyridines, substituted benzenes and substituted ethenes are presented to show the overall performance of the new definition.

Wickramasinghe, Chandra; Wickramasinghe, Kamala

2005-01-01

This is the story of the author's unique scientific journey with one of the most remarkable men of 20th century science. The journey begins in Sri Lanka, the author's native country, with his childhood acquaintance with Fred Hoyle's writings. The action then moves to Cambridge, where the famous Hoyle-Wickramasinghe collaborations begin. A research programme which was started in 1962 on the carbonaceous nature of interstellar dust leads, over the next two decades, to developments that are continued in both Cambridge and Cardiff. These developments prompt Hoyle and the author to postulate the organic theory of cosmic dust (which is now generally accepted), and then to challenge one of the most cherished paradigms of contemporary science - the theory that life originated on Earth in a warm primordial soup.

2012-01-01

The tyrosine kinase inhibitor (TKI) imatinib has improved outcomes for patients with unresectable or metastatic gastrointestinal stromal tumors (GIST), and for patients receiving adjuvant therapy following GIST resection. This qualitative study explored the experiences and emotions of patients through GIST diagnosis, treatment initiation, disease control, and in some patients, loss of response and therapy switch. Ethnographic investigations were conducted, including semi- structured qualitative interviews of patients with resected or metastatic/unresectable GIST and their caregivers, from Canada (n = 15); the United States (n = 10); and Brazil, France, Germany, Russia, and Spain (n = 5 each). Some interviewees also kept 7-day photo journals. Responses were qualitatively analyzed to identify gaps and unmet needs where communication about disease, treatments, and adherence could be effective. Patients shared common experiences during each stage of disease management (crisis, hope, adaptation, new normal, and uncertainty). Patients felt a sense of crisis during diagnosis, followed by hope upon TKI therapy initiation. Over time, they came to adapt to their new lives (new normal) with cancer. With each follow-up, patients confronted the uncertainty of becoming TKI resistant and the possible need to switch therapy. During uncertainty many patients sought new information regarding GIST. Cases of disease progression and drug switching caused patients to revert to crisis and restart their emotional journey. Patients with primary or unresectable/metastatic GIST shared similar journeys, especially regarding uncertainty, although differences in the scope and timing of phases were observed. Strategies patients used to remain adherent included obtaining family support, setting reminder mechanisms, taking medicine at routine times, and storing medicine in prominent places. Physicians and support staff can manage patient expectations and encourage adherence to therapy, which may

The objective of this study was to explore the process of transition into fatherhood for Thai men from childbirth to the postpartum period. Forty-one first-time Thai fathers were voluntarily recruited from two hospitals in Chiang Mai, Thailand, from December 2012 to June 2013. In-depth interviews were used to collect the data, which were analyzed based on grounded theory methodology. The basic social process that emerged as the core category was termed: "the journey into fatherhood." This process was divided into three phases: labor, delivery, and family beginning. Within this process, there were various situations, challenges, and pressures, which caused many changes of mood and feelings for the first-time fathers. Throughout this process, they applied various strategies to manage their concerns and needs, in order to develop into masterly fathers. Identifying the process of the journey into fatherhood provides nurses and midwives insight into the new fathers' experiences, which will enable them to be more sensitive, respectful, and effective caregivers. © 2015 Wiley Publishing Asia Pty Ltd.

The NHS has a target of cutting its carbon dioxide (CO2) emissions by 80% below 1990 levels by 2050. Travel comprises 17% of the NHS carbon footprint. This carbon footprint represents the total CO2 emissions caused directly or indirectly by the NHS. Patient journeys have previously been planned largely without regard to the environmental impact. The potential contribution of 'avoidable' journeys in primary care is significant. To investigate the carbon footprint of patients travelling to and from a general practice surgery, the issues involved, and potential solutions for reducing patient travel. A mixed methods study in a medium-sized practice in Yorkshire. During March 2012, 306 patients completed a travel survey. GIS maps of patients' travel (modes and distances) were produced. Two focus groups (12 clinical and 13 non-clinical staff) were recorded, transcribed, and analysed using a thematic framework approach. The majority (61%) of patient journeys to and from the surgery were made by car or taxi; main reasons cited were 'convenience', 'time saving', and 'no alternative' for accessing the surgery. Using distances calculated via ArcGIS, the annual estimated CO2 equivalent carbon emissions for the practice totalled approximately 63 tonnes. Predominant themes from interviews related to issues with systems for booking appointments and repeat prescriptions; alternative travel modes; delivering health care; and solutions to reducing travel. The modes and distances of patient travel can be accurately determined and allow appropriate carbon emission calculations for GP practices. Although challenging, there is scope for identifying potential solutions (for example, modifying administration systems and promoting walking) to reduce 'avoidable' journeys and cut carbon emissions while maintaining access to health care.

Journey to the center of the galaxy

The solar system is a member of the Orion Arm of the Milky Way, far from the center of the Galaxy. This article takes the reader on a hypothetical journey from the solar system to the center of the Galaxy. Results from radio and infrared studies are used to suggest what such a journey might reveal. Traveling from the solar system toward the center, one crosses the Cygnus Arm, then the Sagittarius Arm, and then the so-called Three-kiloparsec Arm. The Arms contain a mixture of young stars as well as lots of gas and dust. Radio studies show that the Three-kiloparsec Arm is more like a ring than an arm. Inside this ring, is another ring composed of giant molecular clouds. Radio and infrared astronomers have discovered that the heart of the Galaxy is composed of matter in most perplexing states. There are three regions known within this innermost thousand light-years. First, there is a large zone of thin, hot ionized gas. Within this, there is a whirlpool of dense, warm matter. And further embedded, there seems to be a small supermassive object at the center. Possibly this object could be a blackhole. Researchers are continuing to examine, monitor, and model this mysterious region, the galactic nuclei

The college journey and academic engagement: how metaphor use enhances identity-based motivation.

Science.gov (United States)

Landau, Mark J; Oyserman, Daphna; Keefer, Lucas A; Smith, George C

2014-05-01

People commonly talk about goals metaphorically as destinations on physical paths extending into the future or as contained in future periods. Does metaphor use have consequences for people's motivation to engage in goal-directed action? Three experiments examine the effect of metaphor use on students' engagement with their academic possible identity: their image of themselves as academically successful graduates. Students primed to frame their academic possible identity using the goal-as-journey metaphor reported stronger academic intention, and displayed increased effort on academic tasks, compared to students primed with a nonacademic possible identity, a different metaphoric framing (goal-as-contained-entity), and past academic achievements (Studies 1-2). This motivating effect persisted up to a week later as reflected in final exam performance (Study 3). Four experiments examine the cognitive processes underlying this effect. Conceptual metaphor theory posits that an accessible metaphor transfers knowledge between dissimilar concepts. As predicted in this paradigm, a journey-metaphoric framing of a possible academic identity transferred confidence in the procedure, or action sequence, required to attain that possible identity, which in turn led participants to perceive that possible identity as more connected to their current identity (Study 4). Drawing on identity-based motivation theory, we hypothesized that strengthened current/possible identity connection would mediate the journey framing's motivating effect. This mediational process predicted students' academic engagement (Study 5) and an online sample's engagement with possible identities in other domains (Study 6). Also as predicted, journey framing increased academic engagement particularly among students reporting a weak connection to their academic possible identity (Study 7).

2018-05-01

To explore how adult, child and mental health nursing and midwifery students, selected using multiple mini interviews, describe their 'values journey' following exposure to the clinical practice environment. Values based recruitment (VBR) incorporates assessment of healthcare students' personal values using approaches like multiple mini interviews. Students' experience of adjustment to their values during their programme is conceptualized as a 'values journey'. The impact of VBR in alleviating erosion of personal values remains unclear. A cross-professional longitudinal cohort study was commenced at one university in England in 2016 with data collection points at the end of years one, two and three. Non-probability consecutive sampling resulted in 42 healthcare students (8 adult, 8 child and 9 mental health nursing and 17 midwifery students) taking part. Six semi-structured focus groups were conducted at the end of participants' Year One (DC1). Data analysis incorporated inductive and deductive approaches in a hybrid synthesis. Participants described a 'values journey' where their values, particularly communication, courage and wanting to make a difference, were both challenged and retained. Participants personal journeys also acknowledged the: 'courage it takes to use values'; 'reality of values in practice' and 'need for self-reflection on values'. A 'values journey' may begin early in a healthcare student's education programme. This is important to recognize so that appropriate interventions designed to support students in higher education and clinical practice can be implemented. The values incorporated in VBR should be continually evaluated for fitness for purpose. © 2017 John Wiley & Sons Ltd.

Integrated travel network model for studying epidemics: Interplay between journeys and epidemic

Science.gov (United States)

Ruan, Zhongyuan; Wang, Chaoqing; Ming Hui, Pak; Liu, Zonghua

2015-06-01

The ease of travelling between cities has contributed much to globalization. Yet, it poses a threat on epidemic outbreaks. It is of great importance for network science and health control to understand the impact of frequent journeys on epidemics. We stress that a new framework of modelling that takes a traveller’s viewpoint is needed. Such integrated travel network (ITN) model should incorporate the diversity among links as dictated by the distances between cities and different speeds of different modes of transportation, diversity among nodes as dictated by the population and the ease of travelling due to infrastructures and economic development of a city, and round-trip journeys to targeted destinations via the paths of shortest travel times typical of human journeys. An example is constructed for 116 cities in China with populations over one million that are connected by high-speed train services and highways. Epidemic spread on the constructed network is studied. It is revealed both numerically and theoretically that the traveling speed and frequency are important factors of epidemic spreading. Depending on the infection rate, increasing the traveling speed would result in either an enhanced or suppressed epidemic, while increasing the traveling frequency enhances the epidemic spreading.

Westbrook, Johanna I; Coiera, Enrico W; Braithwaite, Jeffrey

2005-01-01

Online evidence retrieval systems are one potential tool in supporting evidence-based practice. We have undertaken a program of research to investigate how hospital-based clinicians (doctors, nurses and allied health professionals) use these systems, factors influencing use and their impact on decision-making and health care delivery. A central component of this work has been the development and testing of a broad range of evaluation techniques. This paper provides an overview of the results obtained from three stages of this evaluation and details the results derived from the final stage which sought to test two methods for assessing the integration of an online evidence system and its impact on decision making and patient care. The critical incident and journey mapping techniques were applied. Semi-structured interviews were conducted with 29 clinicians who were experienced users of the online evidence system. Clinicians were asked to described recent instances in which the information obtained using the online evidence system was especially helpful with their work. A grounded approach to data analysis was taken producing three categories of impact. The journey mapping technique was adapted as a method to describe and quantify clinicians' integration of CIAP into their practice and the impact of this on patient care. The analogy of a journey is used to capture the many stages in this integration process, from introduction to the system to full integration into everyday clinical practice with measurable outcomes. Transcribed interview accounts of system use were mapped against the journey stages and scored. Clinicians generated 85 critical incidents and one quarter of these provided specific examples of system use leading to improvements in patient care. The journey mapping technique proved to be a useful method for providing a quantification of the ways and extent to which clincians had integrated system use into practice, and insights into how information

Journey-time exposures to particulate air pollution were investigated in Leicester, UK, between January and March 2005. Samples of TSP, PM 10, PM 2.5, and PM 1 were simultaneously collected using light scattering devices whilst journeys were made by walking an in-car. Over a period of two months, 33 pairs of walking and in-car measurements were collected along two circular routes. Average exposures while walking were seen to be higher than those found in-car for each of the particle fractions: average walking to in-car ratios were 1.2 (± 0.6), 1.5 (± 0.6), 1.3 (± 0.6), and 1.4 (± 0.6) μg m -3 for coarse (TSP-PM 10), intermediate (PM 10-PM 2.5), fine (PM 2.5-PM 1), and very fine particles (PM 1), respectively. Correlations between walking and in-car exposures were seen to be weak for coarse particles ( r=0.10, p=0.58), moderate for the intermediate particles ( r=0.49, pcar exposures were 25% higher than the same fixed-site monitor. Particles with an aerodynamic diameter of less than 2.5 μm were seen to be highly correlated between walking and in-car particle exposures and a rural fixed-site monitor about 30 km south of Leicester.

A map of the invisible journeys into particle physics

Butterworth, Jon

2017-01-01

What is the universe really made of? How do we know? Follow the map of the invisible to find out... Over the last sixty years, scientists around the world have worked together to explore the fundamental constituents of matter, and the forces that govern their behaviour. The result, so far, is the ‘Standard Model’ of elementary particles: a theoretical map of the basic building blocks of the universe. With the discovery of the Higgs boson in 2012, the map as we know it was completed, but also extended into strange new territory. A Map of the Invisible is an explorer’s guide to the Standard Model and the extraordinary realms of particle physics. After shrinking us down to the size of a sub-atomic particle, pioneering physicist Jon Butterworth takes us on board his research vessel for a journey in search of atoms and quarks, electrons and neutrinos, and the forces that shape the universe. Step by step, discovery by discovery, we journey into the world of the unseen, from the atom to black holes and dark ...

Returning to work: The cancer survivor’s transformational journey of adjustment and coping

Directory of Open Access Journals (Sweden)

Antoni Barnard

2016-11-01

Full Text Available The aim of this study was to explore cancer survivors’ return to work (RTW experience with a specific focus on the adjustment and coping process underlying their journey. The study was conducted in the Southern Cape, South Africa, with eight cancer survivors having returned to work following successful treatment of various types of cancer. Unstructured interviews were conducted and data were analysed following the principles of hermeneutic phenomenological reflection and analysis. Four themes emerged, representing the changing adjustment responses and coping during the RTW journey. Participants evolve from being overwhelmed with emotions and applying avoidant coping to seeking understanding and positive affectivity in their attempt to comprehend the reality of their situation. Participants’ external locus of control change to a more active approach and problem-solving orientation, demonstrating a need to take control and responsibility. Ultimately, adjustment and coping become most constructive when cancer survivors resolve to re-assess life and self through meaning-making, resulting in renewed appreciation of life, appropriate life style changes, and regained confidence in their relational role. A process perspective is proposed to facilitate an understanding of, and working with, cancer survivors’ transition through the RTW journey towards optimal coping phases.

2 Cases of Bullosis Diabeticorum following Long-Distance Journeys by Road: A Report of 2 Cases

Directory of Open Access Journals (Sweden)

Fatima Bello

2012-01-01

Full Text Available Background. Bullosis diabeticorum is a distinct, spontaneous, noninflammatory, and blistering condition of acral skin that is unique to diabetics. It is rare. Exact aetiopathogenesis is not known, but many attributed peripheral neuropathy as a potent risk factor, others hypothesized the role of trauma, UV light, and nephropathy. Aim. To present cases of bullosis diabeticorum following long-distance journeys by road. Methods. History and physical examinations were done on 2 diabetics who presented with bilateral feet bullae following a long journey. Biopsy of a circumferential area of the bullae including adjoining apparently normal skin was done. Results. Features of peripheral neuropathy were noted. One developed digital gangrene without features of peripheral vascular disease. Culture of aspirate from a bullae yielded Staphylococcus aureus. Tissue biopsy showed hyperkeratotic focally acanthotic pigmented epidermis with subcorneal separation of the granular layer of the epidermis by aggregates of viable and nonviable polymorphs and lymphocytes. There is mild acantholysis of the epidermis, and a fibrocollagenous dermis which is moderately infiltrated by lymphocytes. Conclusion. Long journeys by road is a strong factor in the aetiopathogenesis of bullosis diabeticorum on a background of peripheral neuropathy. Diabetics especially those with peripheral neuropathy should be cautious while traveling long journeys by road.

Understanding the requirements of geographical data for blind and partially sighted people to make journeys more independently.

Science.gov (United States)

Chandler, Edward; Worsfold, John

2013-11-01

Previous research has highlighted that blind and partially sighted people find various factors inhibit their abilities to make journeys. This paper proposes that the lack of accurate, appropriate and usable geographical data is one of the reasons for this and these can be tracked back to core human factors issues such as situational awareness, mental workload and environmental ergonomics. Following a review of applicable literature a hierarchical task analysis was performed to better understand the problems in terms of the complexity of various journey types and to identify the geographical data requirements in order to make successful journeys. The task analysis produced a number of results including highlighting four underlying principles which have an impact on the data requirements during any given journey. Finally the need for accessible and accurate geographical data requirements is introduced as a result of the literature review and the task analysis. These highlight the information required in order to facilitate more accessible travel for blind and partially sighted people by providing geographical information about their surroundings in a relevant, meaningful and usable way.

The study investigates the process of recovery for people diagnosed with personality disorder, a client group that suffers significant social exclusion known to impact on demand for health and other public services. It aims to examine efforts that attempt to reverse this social exclusion as an aspect of the recovery process. and The following study aims to (1) explore what recovery means to people with personality disorder; (2) develop a conceptual model of recovery in personality disorder; and (3) evaluate the contribution of the setting (The Haven) to recovery practice. The study uses a Participatory Action Research (PAR) design. Data was collected from 66 participants by focus groups and individual interviews. A map based on thematic analysis of data collected during the study is proposed of the recovery journey for people with this diagnosis, shown as a pyramid that represents a hierarchy of progress, from building trust through stages of recovery to social inclusion. The findings offer contributions to knowledge in terms of the service design and propose a new model of recovery in personality disorder. This is defined as a journey of small steps highlighting recovery as a process rather than a goal, leading to the emergence of the new concept of transitional recovery.

2014-01-01

A priority of the Global Polio Eradication Initiative (GPEI) 2013-2018 strategic plan is to evaluate the potential impact on polio eradication resulting from expanding one or more Supplementary Immunization Activities (SIAs) to children beyond age five-years in polio endemic countries. It has been hypothesized that such expanded age group (EAG) campaigns could accelerate polio eradication by eliminating immunity gaps in older children that may have resulted from past periods of low vaccination coverage. Using an individual-based mathematical model, we quantified the impact of EAG campaigns in terms of probability of elimination, reduction in polio transmission and age stratified immunity levels. The model was specifically calibrated to seroprevalence data from a polio-endemic region: Zaria, Nigeria. We compared the impact of EAG campaigns, which depend only on age, to more targeted interventions which focus on reaching missed populations. We found that EAG campaigns would not significantly improve prospects for polio eradication; the probability of elimination increased by 8% (from 24% at baseline to 32%) when expanding three annual SIAs to 5-14 year old children and by 18% when expanding all six annual SIAs. In contrast, expanding only two of the annual SIAs to target hard-to-reach populations at modest vaccination coverage-representing less than one tenth of additional vaccinations required for the six SIA EAG scenario-increased the probability of elimination by 55%. Implementation of EAG campaigns in polio endemic regions would not improve prospects for eradication. In endemic areas, vaccination campaigns which do not target missed populations will not benefit polio eradication efforts.

The transport of domestic animals by road can increase levels of stress and decrease meat quality, especially in unfavourable climates. The purpose of this study was to investigate the effect of journey duration and vertical position on the transport truck on some physiological indicators of stress and on instrumental meat quality parameters in commercial rabbits. In the summer months (June and July, 2003), 78 rabbits were subjected to either long (7 h) (LJ) or short (1 h) (SJ) journeys (3 replicates each, n = 6) between the farm and an abattoir in northern Spain. The position (top, middle, or bottom) occupied by the rabbits on the Multi-Floor cage Rolling Stand (MFRS) of the transport truck was recorded. Blood samples were collected at sticking and meat pH was measured at 24 h post-mortem (pH24). At 48 h post-mortem, samples of the M. longissimus dorsi were used to determine water-holding capacity (WHC) and instrumental tenderness using an INSTRON machine. The levels of corticosterone, glucose, lactate, and creatine kinase were slightly higher in LJ than in SJ samples, but the difference was not statistically significant (p MFRS showed higher levels (p < or = 0.05) of glucose and creatine kinase (middle), and corticosterone (bottom) than the rabbits located at the top floor. The pH 24 and WHC values of the SJ and LJ rabbits did not differ significantly. Journey length had a significant effect (p < or = 0.01) on meat tenderness. The meat from rabbits subjected to LJ had higher values of maximum stress and total toughness than did the SJ rabbits (p < or = 0.05). There were similar differences (p < or = 0.05) between LJ and SJ rabbits in their stress values of compression at 20% and 40% (measures of the tenderness of raw meat). In hot weather, the position on the transport truck appeared to have a greater effect on rabbit welfare than the duration of the journey.

The educational journeys of first-generation college women in STEM: A grounded theory study

Science.gov (United States)

Geier, Susan

The purpose of this study was to ascertain the various factors that influenced these first-generation college women as they chose a college and selected a STEM major and subsequently persisted to upper level (junior/senior) status. Twenty-five first-generation college women in STEM majors who attended a research-intensive university in the Midwest were interviewed. Approaching this study using constructivist grounded theory provided the opportunity for deeper insights by examining data at a conceptual level while preserving the voices of the women in this study. The women faced numerous challenges on their journeys, yet they persisted. As the women in this study selected and persisted in STEM, they demonstrated thoughtful determination, experienced shifting identities, established purposeful relationships and applied forward thinking, as they practiced high-stakes decision-making during their journeys. The experiences of these women, namely first-generation women in STEM fields, may inform students, parents, educators, researchers, and policymakers concerned with (a) inspiring students to consider STEM majors, (b) fostering student success in STEM throughout their academic journeys, and (c) ultimately increasing the number of underrepresented minorities and women in the STEM fields.

In the past two decades, childhood vaccination coverage has increased dramatically, averting an estimated 2-3 million deaths per year. Adult vaccination coverage, however, remains inconsistently recorded and substandard. Although structural barriers are known to limit coverage, social and psychological factors can also affect vaccine uptake. Previous qualitative studies have explored beliefs, attitudes and preferences associated with seasonal influenza (flu) vaccination uptake, yet little research has investigated how participants' context and experiences influence their vaccination decision-making process over time. This paper aims to provide a detailed account of a mixed methods approach designed to understand the wider constellation of social and psychological factors likely to influence adult vaccination decisions, as well as the context in which these decisions take place, in the USA, the UK, France, India, China and Brazil. We employ a combination of qualitative interviewing approaches to reach a comprehensive understanding of the factors influencing vaccination decisions, specifically seasonal flu and tetanus. To elicit these factors, we developed the journey to vaccination, a new qualitative approach anchored on the heuristics and biases tradition and the customer journey mapping approach. A purposive sampling strategy is used to select participants who represent a range of key sociodemographic characteristics. Thematic analysis will be used to analyse the data. Typical journeys to vaccination will be proposed. Vaccination uptake is significantly influenced by social and psychological factors, some of which are under-reported and poorly understood. This research will provide a deeper understanding of the barriers and drivers to adult vaccination. Our findings will be published in relevant peer-reviewed journals and presented at academic conferences. They will also be presented as practical recommendations at policy and industry meetings and healthcare

Narrating Science and Religion. Storytelling Strategies in Journey of the Universe

Directory of Open Access Journals (Sweden)

Nancy Menning

2016-12-01

Full Text Available While scientific and religious narratives use distinct discourse strategies to reach different audiences, the documentary film Journey of the Universe combines scientific and humanistic perspectives to narrate the origin and evolution of the universe, life on Earth, and human consciousness. This science-based mythic telling of the universe story foregrounds science to enhance the story’s plausibility while using mythic elements to invite an ethical response. We evaluate how this film blends scientific and mythic storytelling strategies to present a plausible story with moral force. Journey of the Universe presents an image of humanity as naturally emerging from an increasingly complex cosmos, capable of profound wonder, and poised to use its intellectual gifts to renew the face of the earth. We argue that narrative strategies aligning scientific content with the viewer’s personal experiences of nature are generally effective, and that the film’s focus on the local and terrestrial, even in the midst of the vastness of the cosmos, supports its ecological message.

Journey Through Intuition

Directory of Open Access Journals (Sweden)

Christina LEGREE

2010-12-01

Full Text Available In this article I wish to share how I learned about intuition through personal experiences and why it is important in education. Intuition is linked to epistemology, language, emotions, health, memory and involves the inner life of the person. For most of my life, I had very little understanding about intuition and deemed this phenomenon as useless in education. I started to learn about intuition as a result of my spouses catastrophic death. The grief I experienced precipitated a loss in my belief system and I felt a significant decrease in my ability to function in a logical or rational manner. My journey into intuition enabled me to forge a new way to live my life. I believe that each person has the ability to learn about intuition and how it can be useful in guiding ones life. The mainstream school system however fails to recognize intuition as a valid way of learning despite the research in this field. Students are therefore being given a partial education. Given this, I feel there is a serious problem which emerges if people are led to believe that the mainstream education system is offering students a complete education.

Development of a novel anisotropic self-inflating tissue expander: in vivo submucoperiosteal performance in the porcine hard palate.

Swan, Marc C; Bucknall, David G; Czernuszka, Jan T; Pigott, David W; Goodacre, Timothy E E

2012-01-01

The advent of self-inflating hydrogel tissue expanders heralded a significant advance in the reconstructive potential of this technique. Their use, however, is limited by their uncontrolled isotropic (i.e., uniform in all directions) expansion. Anisotropy (i.e., directional dependence) was achieved by annealing a hydrogel copolymer of poly(methyl methacrylate-co-vinyl pyrrolidone) under a compressive load for a specified time period. The expansion ratio is dictated by the percentage of vinyl pyrrolidone content and the degree of compression. The expansion rate is modified by incorporating the polymer within a silicone membrane. The in vivo efficacy of differing prototype devices was investigated in juvenile pigs under United Kingdom Home Office Licence. The devices were implanted within a submucoperiosteal pocket in a total of six porcine palates; all were euthanized by 6 weeks after implantation. A longitudinal volumetric assessment of the expanded tissue was conducted, in addition to postmortem analysis of the bony and mucoperiosteal palatal elements. Uncoated devices caused excessive soft-tissue expansion that resulted in mucoperiosteal ulceration, thus necessitating animal euthanasia. The silicone-coated devices produced controlled soft-tissue expansion over the 6-week study period. There was a statistically significant increase in the volume of expanded soft tissue with no evidence of a significant acute inflammatory response to the implant, although peri-implant capsule formation was observed. Attenuation of the bony palatal shelf was noted. A unique anisotropic hydrogel device capable of controlled expansion has been developed that addresses a number of the shortcomings of the technology hitherto available.

2011-01-01

The Centers for Medicare & Medicaid Services' regulations regarding nonpayment for hospital-acquired conditions such as pressure ulcers have prompted a marked increase in focus on preventive care. Our hospital also used this change in payment policy as an opportunity to strengthen our pressure ulcer prevention practices. We used an 8-spoke prevention wheel to develop and implement practice changes that reduced pressure ulcer incidence from 7.3% to 1.3% in 3 years. Because it is about the journey, we will describe the mechanisms we designed and implemented, and identify strategies that worked or did not work as we promulgated a quality improvement process for pressure ulcer prevention in our large urban hospital center.

Bond-orientational analysis of hard-disk and hard-sphere structures.

Science.gov (United States)

Senthil Kumar, V; Kumaran, V

2006-05-28

We report the bond-orientational analysis results for the thermodynamic, random, and homogeneously sheared inelastic structures of hard-disks and hard-spheres. The thermodynamic structures show a sharp rise in the order across the freezing transition. The random structures show the absence of crystallization. The homogeneously sheared structures get ordered at a packing fraction higher than the thermodynamic freezing packing fraction, due to the suppression of crystal nucleation. On shear ordering, strings of close-packed hard-disks in two dimensions and close-packed layers of hard-spheres in three dimensions, oriented along the velocity direction, slide past each other. Such a flow creates a considerable amount of fourfold order in two dimensions and body-centered-tetragonal (bct) structure in three dimensions. These transitions are the flow analogs of the martensitic transformations occurring in metals due to the stresses induced by a rapid quench. In hard-disk structures, using the bond-orientational analysis we show the presence of fourfold order. In sheared inelastic hard-sphere structures, even though the global bond-orientational analysis shows that the system is highly ordered, a third-order rotational invariant analysis shows that only about 40% of the spheres have face-centered-cubic (fcc) order, even in the dense and near-elastic limits, clearly indicating the coexistence of multiple crystalline orders. When layers of close-packed spheres slide past each other, in addition to the bct structure, the hexagonal-close-packed (hcp) structure is formed due to the random stacking faults. Using the Honeycutt-Andersen pair analysis and an analysis based on the 14-faceted polyhedra having six quadrilateral and eight hexagonal faces, we show the presence of bct and hcp signatures in shear ordered inelastic hard-spheres. Thus, our analysis shows that the dense sheared inelastic hard-spheres have a mixture of fcc, bct, and hcp structures.

Tissue expander infections in children: look beyond the expander pocket.

Science.gov (United States)

Mason, A C; Davison, S P; Manders, E K

1999-11-01

Infection of the expander pocket is the most common complication encountered with soft-tissue expansion. It is usually due to direct inoculation with skin flora either at the time of expander insertion or from extrusion of the device. The authors report two cases of infection of tissue expanders in which the children had concomitant infected sites distant from the prosthesis. Etiological bacteria of common pediatric infections like otitis media and pharyngitis were cultured from the infected expander pocket, raising suspicion that translocation of the organism to the expander had occurred. Aggressive antibiotic treatment, removal of the prosthesis, and flap advancement is advocated.

1996-03-01

Research results of hard photon technology have been summarized as a part of novel technology development highly utilizing the quantum nature of photon. Hard photon technology refers to photon beam technologies which use photon in the 0.1 to 200 nm wavelength region. Hard photon has not been used in industry due to the lack of suitable photon sources and optical devices. However, hard photon in this wavelength region is expected to bring about innovations in such areas as ultrafine processing and material synthesis due to its atom selective reaction, inner shell excitation reaction, and spatially high resolution. Then, technological themes and possibility have been surveyed. Although there are principle proposes and their verification of individual technologies for the technologies of hard photon generation, regulation and utilization, they are still far from the practical applications. For the photon source technology, the laser diode pumped driver laser technology, laser plasma photon source technology, synchrotron radiation photon source technology, and vacuum ultraviolet photon source technology are presented. For the optical device technology, the multi-layer film technology for beam mirrors and the non-spherical lens processing technology are introduced. Also are described the reduction lithography technology, hard photon excitation process, and methods of analysis and measurement. 430 refs., 165 figs., 23 tabs.

Full Text Available This study aimed to investigate some challenges female doctoral students experience in their doctoral journey. The study used a qualitative design and structured interviews. The theoretical framework that guided the study was that of Urie Bronfenbrenner’s ecosystemic theory. A purposely selected sample of five female doctoral students from the University of South Africa Ethiopia campus participated in the study. The results identified three major areas of concern such as: academic, psychosocial and home/work related. Specifically, female doctoral students reported concerns surrounding quality of supervision support, inadequate academic skill, nature or system of education, stress, motivation, isolation, balancing personal and professional life, relationship problems, home and work related concerns. Hence, universities must provide opportunities and resourceful strategies to meet the challenges posed by women scholars in the doctoral journey.

Moving the Journey Towards Independence: Adolescents Transitioning to Successful Diabetes Self-Management.

Science.gov (United States)

Babler, Elizabeth; Strickland, Carolyn June

2015-01-01

To gain a greater understanding of adolescent's experiences living with Type 1 diabetes mellitus (T1DM) and create a theoretical paradigm. Grounded theory as described by Glaser was used. Fifteen in-depth interviews were conducted with adolescent's ages 11-15 with T1DM. Symbolic interactionism is the theoretical framework for grounded theory. Data were collected; transcribed, coded, and analyzed simultaneously using constant comparative analysis and findings were grounded in the words of participants. A theoretical model was created with the concept of "normalizing". Normalizing was defined as the ability to integrate diabetes into one's daily life to make diabetes 'part of me'. Phase four of the model, and the focus of this manuscript was "Moving the Journey towards Independence" and included: 1) taking over care, 2) experiencing conflict with parents, and 3) realizing diabetes is hard. The major task for adolescents in this phase was separating from parents to independently manage diabetes. The normalizing task for this phase was: "taking on the burden of care". Adolescents described challenges with independent care and increased parental conflict including: fearing needles, forgetting insulin, feeling embarrassed and believing that diabetes was a burden in their life. Additionally, juggling the multiple responsibilities of home, school and work along with managing a chronic illness during adolescence is challenging. Transitioning to diabetes self-management is a challenge for adolescents. This model advances understanding of the moving processes in adolescents transitioning; additionally, hypotheses are presented that may be used for developing interventions to promote success in self-management.

Accessing Creativity: Jungian Night Sea Journeys, Wandering Minds, and Chaos.

Science.gov (United States)

Rosen, Diane

2016-01-01

NDS theory has been meaningfully applied to the dynamics of creativity and psychology. These complex systems have much in common, including a broad definition of "product" as new order emerging from disorder, a new whole (etymologically, 'health') out of disintegration or destabilization. From a nonlinear dynamical systems perspective, this paper explores the far-from-equilibrium zone of creative incubation: first in the Jungian night sea journey, a primordial myth of psychological and creative transformation; then in the neuroscience of mind wandering, the well-spring of creative ideation within the larger neural matrix. Finally, chaos theory grounds the elusive subject of creativity, modeling chaotic generation of idea elements that tend toward strange attractors, combine unpredictably, and produce change by means of tension between opposites, particularly notes consciousness (light) and the poetic unconscious (darkness). Examples from my own artwork illustrate this dialectical process. Considered together, the unconscious mythic sea journey, the unknowing wandering mind, and the generative paradigm of deterministic chaos suggest conditions that facilitate creativity across disciplines, providing fresh indications that the darkness of the unknown or irrational is, paradoxically, the illuminative source and strength of creativity.

In search of plutonium: A nonproliferation journey

Science.gov (United States)

Hecker, Siegfried

2010-02-01

In February 1992, I landed in the formerly secret city of Sarov, the Russian Los Alamos, followed a few days later by a visit to Snezhinsk, their Livermore. The briefings we received of the Russian nuclear weapons program and tours of their plutonium, reactor, explosives, and laser facilities were mind boggling considering the Soviet Union was dissolved only two months earlier. This visit began a 17-year, 41 journey relationship with the Russian nuclear complex dedicated to working with them in partnership to protect and safeguard their weapons and fissile materials, while addressing the plight of their scientists and engineers. In the process, we solved a forty-year disagreement about the plutonium-gallium phase diagram and began a series of fundamental plutonium science workshops that are now in their tenth year. At the Yonbyon reprocessing facility in January 2004, my North Korean hosts had hoped to convince me that they have a nuclear deterrent. When I expressed skepticism, they asked if I wanted to see their ``product.'' I asked if they meant the plutonium; they replied, ``Well, yes.'' Thus, I wound up holding 200 grams of North Korean plutonium (in a sealed glass jar) to make sure it was heavy and warm. So began the first of my six journeys to North Korea to provide technical input to the continuing North Korean nuclear puzzle. In Trombay and Kalpakkam a few years later I visited the Indian nuclear research centers to try to understand how India's ambitious plans for nuclear power expansion can be accomplished safely and securely. I will describe these and other attempts to deal with the nonproliferation legacy of the cold war and the new challenges ahead. )

Place attachment and social legitimacy: Revisiting the sustainable entrepreneurship journey

OpenAIRE

Kibler, E; Fink, M; Lang, R; Munoz, PA

2015-01-01

This paper revisits the sustainable entrepreneurship journey by introducing a ‘place- based’ sustainable venture path model. We suggest that distinguishing between emo- tional (‘caring about the place’) and instrumental (‘using the place’) place attachment of sustainable entrepreneurs deepens our understanding of how place-based challenges of sustainable venture legitimacy are managed over time. We conclude with avenues for future sustainable entrepreneurship research.

To evaluate the effectiveness of the Acceptance Journeys social marketing campaign to reduce homophobia in the Black community in Milwaukee, Wisconsin. We assessed the campaign's effectiveness using a rolling cross-sectional survey. Data were collected annually online between 2011 and 2015. Each year, a unique sample of Black and White adults, aged 30 years and older, were surveyed in the treatment city (Milwaukee) and in 2 comparison cities that did not have antihomophobia campaigns (St. Louis, MO, and Cleveland, OH; for total sample, n = 3592). Black self-identification and Milwaukee residence were significantly associated with exposure to the campaign, suggesting successful message targeting. The relationship between exposure and acceptance of gay men was significantly mediated through attitudes toward gay men, perceptions of community acceptance, and perceptions of the impact of stigma on gay men, but not through rejection of stereotypes. This model accounted for 39% of variance in acceptance. This evidence suggests that the Acceptance Journeys model of social marketing may be a promising strategy for addressing homophobia in US Black communities.

It considers challenges and ethical issues in the therapeutic partnership with an abuse survivor, exploring the importance of the theoretical framework and of supervision. Issues of autonomy and power in relation both to therapy and to church pastoral practices receive attention. Central to this therapeutic journey is the role of creative methodology, metaphor and myth in facilitating transformation.

Ideal quantum gas in an expanding cavity: nature of nonadiabatic force.

Nakamura, K; Avazbaev, S K; Sobirov, Z A; Matrasulov, D U; Monnai, T

2011-04-01

We consider a quantum gas of noninteracting particles confined in the expanding cavity and investigate the nature of the nonadiabatic force which is generated from the gas and acts on the cavity wall. First, with use of the time-dependent canonical transformation, which transforms the expanding cavity to the nonexpanding one, we can define the force operator. Second, applying the perturbative theory, which works when the cavity wall begins to move at time origin, we find that the nonadiabatic force is quadratic in the wall velocity and thereby does not break the time-reversal symmetry, in contrast with general belief. Finally, using an assembly of the transitionless quantum states, we obtain the nonadiabatic force exactly. The exact result justifies the validity of both the definition of the force operator and the issue of the perturbative theory. The mysterious mechanism of nonadiabatic transition with the use of transitionless quantum states is also explained. The study is done for both cases of the hard- and soft-wall confinement with the time-dependent confining length. ©2011 American Physical Society

Casteletti, L.C.; Fernandes, F.A.P.; Heck, S.C.; Gallego, J.

2010-01-01

In this work nitrided layers deposited on austenitic and super austenitic stainless steels were analyzed through optical microscopy and X-rays diffraction analysis (XRD). It was observed that the formation of N supersaturated phase, called expanded austenite, has promoted significant increment of hardness (> 1000HV). XRD results have indicated the anomalous displacement of the diffracted peaks, in comparison with the normal austenite. This behavior, combined with peaks broadening, it was analyzed in different nitriding temperatures which results showed good agreement with the literature. (author)

Li, Ruguang; Zhu, Jiaoqun; Zhou, Weibing; Cheng, Xiaomin; Li, Yuanyuan

2016-01-01

Highlights: • Expanded Perlite/Sodium Nitrate composites hardly reported in thermal storage fields. • The thermal compatibility and adsorption of Expanded Perlite were investigated. • The thermo physic properties of composites were determined. • The thermal stability and long term enthalpy changes of composites were investigated. - Abstract: The present work focused on the preparation and characterization of a new thermal storage material applied in thermal energy management. X-ray diffraction (XRD) results showed that Expanded Perlite (EP) has a good thermal stability varying from 300 °C to 900 °C. Morphology of scanning electron microscopy (SEM) revealed that sodium nitrate is uniformly encapsulated and embedded in the three-dimensional network structure of EP. Fourier transform infrared (FT-IR) spectroscopy indicated that the EP is physically combined with the nitrate salt. Thermo-gravimetric analysis (TGA) and differential Scanning Calorimeter (DSC) indicated that the composites have good thermal stability. The adsorption capacity of loose EP was 213.21%. When the EP mass fraction varying from 10% to 60%, thermal conductivity decreased with the content of EP increased, and the highest thermal conductivity is 1.14 W (m K)"−"1 at 300 °C. SEM revealed the network structure of EP provided thermal conduction paths which enhanced the thermal conductivity of the composites. All results indicated that EP could be a good adsorption material to be applied in the thermal storage fields.

Refocusing Seafood Sustainability as a Journey Using the Law of the Minimum

Directory of Open Access Journals (Sweden)

Elizabeth Fitzsimons

2012-08-01

Full Text Available Globally, seafood is an important protein source because it is a nutritious food source produced with relative efficiency compared to other proteins. Because of problems related to overfishing and deleterious environmental impacts, over the last decade, non-governmental organizations (NGOs have increased their focus on seafood sustainability while businesses have incorporated this issue into their corporate social responsibility (CSR reporting. Sustainability is a concept that can be addressed in terms of scale of issues considered (narrow vs. broad as well as the scope of how they are measured (undemanding or demanding. Currently, the message of seafood sustainability is becoming complicated in that the journey toward sustainability is being referred to as having achieved a state of sustainability. In addition, companies making a “sustainable” declaration are often at different points in the “scale/scope” arena. As a result, buyers, retailers and consumers have difficulty differentiating between these products. Furthermore, they often assume that a “sustainable” product has no further need for improvement, when in fact this is rarely the case. This change in reference from a continual process (a journey to a static point (it is sustainable limits further advances in seafood sustainability and the drive for continual improvement. Herein, the “Law of the Minimum”, growth toward an end goal will occur until one factor becomes limiting, is adopted as an analogy for sustainability. By refocusing the sustainability discussion on a progressive series of challenges to be met, the discussion will return to the journey as the central point. Doing so will help refresh the dialogue around seafood, and to create new opportunities for improvement.

Remember Hard but Think Softly: Metaphorical Effects of Hardness/Softness on Cognitive Functions

Directory of Open Access Journals (Sweden)

Jiushu Xie

2016-09-01

Full Text Available Previous studies have found that bodily stimulation, such as hardness, biases social judgment and evaluation via metaphorical association; however, it remains unclear whether bodily stimulation also affects cognitive functions, such as memory and creativity. The current study used metaphorical associations between hard and rigid and between soft and flexible in Chinese, to investigate whether the experience of hardness affected cognitive functions requiring either rigidity (memory or flexibility (creativity. In Experiment 1, we found that Chinese-speaking participants performed better at recalling previously memorized words while sitting on a hard-surface stool (the hard condition than a cushioned one (the soft condition. In Experiment 2, participants sitting on a cushioned stool outperformed those sitting on a hard-surface stool on a Chinese riddle task, which required creative/flexible thinking, but not on an analogical reasoning task, which required both rigid and flexible thinking. The results suggest the hardness experience affects cognitive functions that are metaphorically associated with rigidity and flexibility. They support the embodiment proposition that cognitive functions and representations could be grounded via metaphorical association in bodily states.

A humanistic approach to paediatric radiation therapy – One family's journey

International Nuclear Information System (INIS)

Collier, David

2013-01-01

Purpose: To present a patient view of a treatment journey, highlighting the strengths and the weaknesses from that experience and recognising a potential for Advanced Practice on behalf of Radiation Therapists. The patient was aged 7 when diagnosed in December 2007 with an anaplastic ependymona tumour in the occipital lobe and had surgery to effect maximal tumour resection. The pathology of the tumour upon removal indicated that it was a Grade III anaplastic ependymoma some 3 cm across. In early 2008 the patient embarked on radiation therapy receiving 59.4 Gy over 33 treatments. This case was an inaugural patient for a novel intervention which aimed at reducing anxiety and helping the patient to cope with paediatric radiotherapy. The intervention was outstandingly successful and the diversionary activities within the treatment regime undoubtedly added to the effectiveness of the treatment. The patient maintained near normal daily activities missing only the first couple of hours of school each day during the treatment period. The paper will cover this from that patient's perspective and then report on the post treatment impact of that treatment. It will present the patient's view and outcomes in the evolution of the patient management process and improved healthcare. Results: The paper identifies the important role of communication and understanding amongst all members of the team, including the patient. It comments on the need to recognise the full range of options available and the best practice guidelines which could be adopted. Above it touches on the impact the adoption of all of these has on the patient treatment journey. It opens up the question of the appropriate mechanisms of involvement for the patient in this journey and the associated decision making surrounding this involvement, and this paper specifically comments on this. It identifies other professionals' world-wide who are working on elements of this approach. Conclusion: The paper will highlight

Takada, Yoshie

2017-08-01

The landscape architect Maggie Jencks felt that she wanted a place to "get herself back" when her breast cancer recurred and was told that she only had a few months remaining. Mr. Charles Jencks, her husband who fulfilled her wishes, opened the first "Maggie's Cancer Caring Centre" in Edinburgh in 1996. Masako Akiyama, the chief of Maggie's Tokyo found out about Maggie's Centre when she listened to a presentation from Andrew Anderson, the director of Maggie's Edinburgh, at an International Nursing Seminar in 2008. Masako Akiyama realized that support to "get back ones own power" is one of the important things. In addition, she felt that providing a "place" and "support" to patients and their families were predominant elements. When someone is diagnosed with cancer, the person gets a great shock and feels loneliness. Suddenly the person feels tomorrow will not come, every day becomes uncertain. These feelings affect their whole life such as enrollment, employment, loss of role, and change. They also affect people such as family, friends, colleagues, besides the person. Due to changes in treatment, the existential troubles that have been prolonged after the completion of the initial treatment appear. Cancer survivorship is called "Cancer journey"in the Maggie's flow. The cancer journey suddenly starts, when a person is diagnosed with cancer", without direction or a plan. Additionally, the "heart"is often left behind. To undertake the cancer journey, there are a lot of forks in the road that cannot turn back and they are urged to choose their path. "Where now ?"is a phrase in a pamphlet from Maggie's Centre, and the phrase shows that staff of Maggie's Centre can help cancer patient to recognize where they are in their Cancer journey. The Maggie's Centre has 2 important pillars: "building/environment"and "human support". As a "homely place" between hospital and my house, the building is "a healing space". Human support is provided free of charge and patients and

Expandable stents.

Science.gov (United States)

Nesbitt, J C; Carrasco, H

1996-05-01

Expandable metallic stents are effective in selected patients with malignant or benign airway stenoses. When used for malignant lesions, the primary purpose of the stent is to improve the quality of life; stents are usually chosen for palliation of symptoms in recognition of the low likelihood of success for other therapy. For patients with benign stenoses, the stents provide a permanent source of structural support to alleviate the narrowed segment. The advantages of the expandable metallic stents are as follows: (1) they can be inserted through an endotracheal tube or under local anesthesia with relative simplicity under fluoroscopic guidance; (2) they do not impair the drainage of sputum because ciliary movement is not interrupted; (3) over a period of a few weeks, the meshwork is gradually covered with mucosa as the stent becomes incorporated into the airway wall; (4) ventilation usually is not impaired if the metallic mesh stent covers another nonstenosed bronchus, because the interstices of the stent are nonobstructive; and (5) they are dynamic and continue to expand over time, particularly if concurrent treatment achieves an effect on the lesion that caused stenosis. Disadvantages of the expandable stent include (1) they often are only temporarily effective for tracheobronchial stenosis due to intraluminal tumor or granulation tissue, both of which can grow between the wires; (2) they are considered permanent stents because removal is difficult; and (3) they can be poorly positioned during placement or can become displaced by progressive migration after placement, and they cannot be repositioned. A relative contraindication to insertion is an inflammatory process or infection that can predispose to granulation formation, particularly at the points of maximal contact pressure of the stent to the airway mucosa. In the presence of inflammation, it may be better to use a silicone prosthesis until the inflammatory process subsides and fibrosis occurs. Granulation

The Relationship Between Health Management and Information Behavior Over Time: A Study of the Illness Journeys of People Living With Fibromyalgia.

Science.gov (United States)

Chen, Annie T

2016-10-25

Over the course of a chronic illness, patients face many challenges, including understanding what is happening to them and developing an effective strategy for managing illness. While there is existing literature concerning how people seek health-related information and cope with chronic illnesses, there is a need for additional research on how information affects patients' understandings of their illness, and how changes in this understanding affect their health management strategies over time. This study examined how health management, information seeking, and information consumption and use processes are related throughout an illness. A diversified recruitment strategy involving multiple media channels was used to recruit participants for an interview study. During the interviews, participants were asked to draw an "illness journey" timeline. The data were analyzed using a qualitative approach drawn from Interpretative Phenomenological Analysis and Grounded Theory. The study identified four main health management features of illness journeys: onset, progression toward diagnosis, acceptance, and development of an effective management strategy. The study then focused on how information seeking changes over illness journeys, particularly in terms of a transition from active information seeking to monitoring with intermittent focused searching. Last, the paper describes the information consumption and use processes that patients engaged in throughout their journey. This study makes three important contributions to the field. First, it presents an integrated conceptualization of how health management and information behaviors are related on illness journeys. Second, it adds to our existing knowledge on health literacy and self-management of chronic illness. Third, the study has implications for health interface design.

This paper is about the intense experience of being in the hospital in a comatose state resulting from an aneurysm with a massive brain hemorrhage and two subsequent surgeries. The event begins with a premonition of what will happen from a street name. The experience of brain surgeries, along with the fine care of the nurses, left me with a truly memorable impression. This paper describes the various feelings and strong emotions that I experienced while in a comatose state. It suggests that a patient in a comatose state can exist in a deep state of emotions close to ecstasy. The paper concludes with gratefulness to all the people who followed me step by step on this journey.

Hard coal; Steinkohle

Energy Technology Data Exchange (ETDEWEB)

Loo, Kai van de; Sitte, Andreas-Peter [Gesamtverband Steinkohle e.V., Herne (Germany)

2013-04-01

The year 2012 benefited from a growth of the consumption of hard coal at the national level as well as at the international level. Worldwide, the hard coal still is the number one energy source for power generation. This leads to an increasing demand for power plant coal. In this year, the conversion of hard coal into electricity also increases in this year. In contrast to this, the demand for coking coal as well as for coke of the steel industry is still declining depending on the market conditions. The enhanced utilization of coal for the domestic power generation is due to the reduction of the nuclear power from a relatively bad year for wind power as well as reduced import prices and low CO{sub 2} prices. Both justify a significant price advantage for coal in comparison to the utilisation of natural gas in power plants. This was mainly due to the price erosion of the inexpensive US coal which partly was replaced by the expansion of shale gas on the domestic market. As a result of this, the inexpensive US coal looked for an outlet for sales in Europe. The domestic hard coal has continued the process of adaptation and phase-out as scheduled. Two further hard coal mines were decommissioned in the year 2012. RAG Aktiengesellschaft (Herne, Federal Republic of Germany) running the hard coal mining in this country begins with the preparations for the activities after the time of mining.

A Passionate Journey Info-Motion Graphics Video Exploring Why and How to Find Work You Love

Science.gov (United States)

Zhou, Jia

Benjamin Disraeli, a 19th century British Prime Minister, once said, "Man is not a rational animal. He is only truly good or great when he acts from passion." Passion is the fuel that can power you toward the realization of your dreams. To live a truly satisfying and purposeful life, it is important for every individual to know what their passions are so life will be fulfilling. Teenagers choose their career after they graduate from high school. They begin to wonder what they will become and what contributions they can make in the future. It is important for people to choose something interesting that leads them to work hard in their career. This thesis is a motion graphics piece called "A Passionate Journey." It presents an idea to students to help them contemplate about the things in which they have always been interested, discover their true passions, and choose jobs based on their enthusiasm. When people pursue something of which they are fond, they ultimately become successful. Information is received by people's minds, silencing their inner critics and offering them the courage and self-confidence to purse whatever they love. Therefore, the goal of this motion graphic design is help people to start observing themselves, think about what always makes them passionate, and choose something about which they are passionate in their future careers.

Hard and soft age discrimination: the dual nature of workplace discrimination.

Science.gov (United States)

Stypinska, Justyna; Turek, Konrad

2017-03-01

The paper concentrates on the problem of age discrimination in the labour market and the way it can be conceptualised and measured in a multi-disciplinary way. The approach proposed here combines two understandings of age discrimination-a sociological and legal one, what allows for a fuller and expanded understanding of ageism in the workplace. At the heart of the study is a survey carried out in Poland with a sample of 1000 men and women aged 45-65 years. The study takes a deeper and innovative look into the issue of age discrimination in employment. Confirmatory factor analysis with WLSMV estimation and logistic regressions were used to test the hypotheses. The study shows that age discrimination in labour market can take on different forms: hard and soft, where the hard type of age discrimination mirrors the legally prohibited types of behaviours and those which relate to the actual decisions of employers which can impact on the employee's career development. The soft discrimination corresponds with those occurrences, which are not inscribed in the legal system per se, are occurring predominantly in the interpersonal sphere, but can nevertheless have negative consequences. Soft discrimination was experienced more often (28.6% of respondents) than hard discrimination (15.7%) with higher occurrences among women, persons in precarious job situation or residents of urban areas. The role of education was not confirmed to influence the levels of perceived age discrimination.

The magnificent journey

International Nuclear Information System (INIS)

The annual run of Northwest salmon--from the vast Pacific Ocean to the mountain streams where their lives began--is one of Nature's most awe-inspiring events. Now that modern science has discovered some of the salmon's secrets, their journey seems even more miraculous. So unlikely is the survival of a single returning salmon that Nature compensates heavily. Of the other 3,000 to 7,000 eggs in a nest, only one spawning pair, on average, will make it back. Too much or too little water at hatching can wipe out great swarms of young fish life. Bigger fish, bears, seals--all take their share of salmon. Nature allows for these natural events. But Nature alone cannot make up for what people have done. Dams in the Columbia River Basin have blocked huge areas of the wild salmon's spawning grounds. Roads and towns sprouted up along rivers and streams. Logging and farming practices fouled rivers and creeks. So did pollution from the cities. And it became too easy to catch fish. Salmon runs became smaller and smaller. Some types of salmon disappeared forever. Having nearly destroyed the salmon, people are now coming to their rescue. Still, important runs of Northwest native salmon are in real danger of extinction. Much remains to be done. This brochure presents a close look at the life of a wild salmon, Oncorhynchus tshawystcha

Solar journey: The significance of our galactic environment for the heliosphere and earth

Frisch, Priscilla C

2006-01-01

Humans evolved when the Sun was in the great void of the Local Bubble. The Sun entered the present environment of interstellar clouds only during the late Quaternary. Astronomical data reveal these long and short term changes in our galactic environment. Theoretical models then tell us how these changes affect interplanetary particles, planetary magnetospheres, and the Earth itself. Cosmic rays leave an isotopic signature in the paleoclimate record that helps trace the solar journey through space. "Solar Journey: The Significance of Our Galactic Environment for the Heliosphere and Earth" lays the foundation for an interdisciplinary study of the influence of interstellar material on the solar system and Earth as we travel through the Milky Way Galaxy. The solar wind bubble responds dynamically to interstellar material flowing past the Sun, regulating interstellar gas, dust, and cosmic particle fluxes in the interplanetary medium and the Earth. Cones of interstellar gas and dust focused by solar gravity, the ma...

In the present investigation, the possible effects of the expansion of the Universe on systems bonded either by gravitational or electromagnetic forces, are reconsidered. It will be shown that the acceleration (positive or negative) of the expanding background, is the determinant factor affecting planetary orbits and atomic sizes. In the presently accepted cosmology (ΛCDM) all bonded systems are expanding at a decreasing rate that tends to be zero as the universe enters in a de Sitter phase. It is worth mentioning that the estimated expansion rates are rather small and they can be neglected for all practical purposes.

Hard spectator interactions in B → ππ at order α2s

International Nuclear Information System (INIS)

Pilipp, V.

2007-01-01

In the present thesis I discuss the hard spectator interaction amplitude in B → ππ at NLO i.e. at O(α 2 s ). This special part of the amplitude, whose LO starts at O(α s ), is defined in the framework of QCD factorization. QCD factorization allows to separate the short- and the long-distance physics in leading power in an expansion in Λ QCD /m b , where the short-distance physics can be calculated in a perturbative expansion in α s . Compared to other parts of the amplitude hard spectator interactions are formally enhanced by the hard collinear scale √(Λ QCD m b ), which occurs next to the mb-scale and leads to an enhancement of α s . From a technical point of view the main challenges of this calculation are due to the fact that we have to deal with Feynman integrals that come with up to five external legs and with three independent ratios of scales. These Feynman integrals have to be expanded in powers of Δ QCD /m b . I discuss integration by parts identities to reduce the number of master integrals and differential equations techniques to get their power expansions. A concrete implementation of integration by parts identities in a computer algebra system is given in the appendix. Finally I discuss numerical issues like scale dependence of the amplitudes and branching ratios. It turns out that the NLO contributions of the hard spectator interactions are important but small enough for perturbation theory to be valid. (orig.)

For the application of photon to industrial technologies, in particular, a hard photon technology was surveyed which uses photon beams of 0.1-200nm in wavelength. Its features such as selective atom reaction, dense inner shell excitation and spacial high resolution by quantum energy are expected to provide innovative techniques for various field such as fine machining, material synthesis and advanced inspection technology. This wavelength region has been hardly utilized for industrial fields because of poor development of suitable photon sources and optical devices. The developmental meaning, usable time and issue of a hard photon reduction lithography were surveyed as lithography in ultra-fine region below 0.1{mu}m. On hard photon analysis/evaluation technology, the industrial use of analysis, measurement and evaluation technologies by micro-beam was viewed, and optimum photon sources and optical systems were surveyed. Prediction of surface and surface layer modification by inner shell excitation, the future trend of this process and development of a vacuum ultraviolet light source were also surveyed. 383 refs., 153 figs., 17 tabs.

Thermodynamic perturbation theory for fused hard-sphere and hard-disk chain fluids

Zhou, Y.; Hall, C.K.; Stell, G.

1995-01-01

We find that first-order thermodynamic perturbation theory (TPT1) which incorporates the reference monomer fluid used in the generalized Flory--AB (GF--AB) theory yields an equation of state for fused hard-sphere (FHS) chain fluids that has accuracy comparable to the GF--AB and GF--dimer--AC theories. The new TPT1 equation of state is significantly more accurate than other extensions of the TPT1 theory to FHS chain fluids. The TPT1 is also extended to two-dimensional fused hard-disk chain fluids. For the fused hard-disk dimer fluid, the extended TPT1 equation of state is found to be more accurate than the Boublik hard-disk dimer equation of state. copyright 1995 American Institute of Physics

“A journey around the world”: Parent narratives of the journey to pediatric resective epilepsy surgery and beyond

OBJECTIVE Although shorter time to pediatric resective epilepsy surgery is strongly associated with greater disease severity, other non-clinical diagnostic and sociodemographic factors also play a role. We aimed to examine parent-reported barriers to timely receipt of pediatric epilepsy surgery. METHODS We conducted 37 interviews of parents of children who previously had resective epilepsy surgery at UCLA (2006–2011). Interviews were audio-recorded, transcribed and systematically coded using thematic analysis by two independent coders and subsequently checked for agreement. Clinical data, including `time to surgery' (age of epilepsy onset to surgery) were abstracted from medical records. RESULTS The mean time to surgery was 5.3 years (SD=3.8); surgery types included 32% hemispherectomy, 43% lobar/focal, 24% multilobar. At surgery, parents were on average 38.4 years (SD=6.6) and children were 8.2 years (SD=4.7). The more arduous and longer aspect of the journey to surgery was perceived by parents to be experienced prior to presurgical referral. The time from second anti-epileptic drug failure to presurgical referral was ≥1 year in 64% of children. Thematic analysis revealed four themes (with subthemes) along the journey to surgery and beyond: (1) recognition: “something is wrong” (unfamiliarity with epilepsy, identification of medical emergency), (2) searching and finding: “a circuitous journey” (information seeking, finding the right doctors, multiple medications, insurance obstacles, parental stress), (3) surgery is a viable option: “the right spot” (surgery as last resort, surgery as best option, hoping for candidacy), and (4) life now: “we took the steps we needed to” (a new life, giving back). SIGNIFICANCE Multi-pronged interventions targeting parent-, provider- and system-based barriers should focus on the critical presurgical referral period; such interventions are needed to remediate delays and improve access to subspecialty care for

Hard-on-hard lubrication in the artificial hip under dynamic loading conditions.

Directory of Open Access Journals (Sweden)

Robert Sonntag

Full Text Available The tribological performance of an artificial hip joint has a particularly strong influence on its success. The principle causes for failure are adverse short- and long-term reactions to wear debris and high frictional torque in the case of poor lubrication that may cause loosening of the implant. Therefore, using experimental and theoretical approaches models have been developed to evaluate lubrication under standardized conditions. A steady-state numerical model has been extended with dynamic experimental data for hard-on-hard bearings used in total hip replacements to verify the tribological relevance of the ISO 14242-1 gait cycle in comparison to experimental data from the Orthoload database and instrumented gait analysis for three additional loading conditions: normal walking, climbing stairs and descending stairs. Ceramic-on-ceramic bearing partners show superior lubrication potential compared to hard-on-hard bearings that work with at least one articulating metal component. Lubrication regimes during the investigated activities are shown to strongly depend on the kinematics and loading conditions. The outcome from the ISO gait is not fully confirmed by the normal walking data and more challenging conditions show evidence of inferior lubrication. These findings may help to explain the differences between the in vitro predictions using the ISO gait cycle and the clinical outcome of some hard-on-hard bearings, e.g., using metal-on-metal.

Using Social Media and Targeted Snowball Sampling to Survey a Hard-to-reach Population: A Case Study

Directory of Open Access Journals (Sweden)

Gary Dusek

2015-08-01

Full Text Available Response rates to the academic surveys used in quantitative research are decreasing and have been for several decades among both individuals and organizations. Given this trend, providing doctoral students an opportunity to complete their dissertations in a timely and cost effective manner may necessitate identifying more innovative and relevant ways to collect data while maintaining appropriate research standards and rigor. The case of a research study is presented which describes the data collection process used to survey a hard-to-reach population. It details the use of social media, in this case LinkedIn, to facilitate the distribution of the web-based survey. A roadmap to illustrate how this data collection process unfolded is presented, as well as several “lessons learned” during this journey. An explanation of the considerations that impacted the sampling design is provided. The goal of this case study is to provide researchers, including doctoral students, with realistic expectations and an awareness of the benefits and risks associated with the use of this method of data collection.

Remember Hard But Think Softly: Metaphorical Effects of Hardness/Softness on Cognitive Functions

Xie, Jiushu; Lu, Zhi; Wang, Ruiming; Cai, Zhenguang G.

2016-01-01

Previous studies have found that bodily stimulation, such as hardness biases social judgment and evaluation via metaphorical association; however, it remains unclear whether bodily stimulation also affects cognitive functions, such as memory and creativity. The current study used metaphorical associations between “hard” and “rigid” and between “soft” and “flexible” in Chinese, to investigate whether the experience of hardness affects cognitive functions whose performance depends prospectively on rigidity (memory) and flexibility (creativity). In Experiment 1, we found that Chinese-speaking participants performed better at recalling previously memorized words while sitting on a hard-surface stool (the hard condition) than a cushioned one (the soft condition). In Experiment 2, participants sitting on a cushioned stool outperformed those sitting on a hard-surface stool on a Chinese riddle task, which required creative/flexible thinking, but not on an analogical reasoning task, which required both rigid and flexible thinking. The results suggest the hardness experience affects cognitive functions that are metaphorically associated with rigidity or flexibility. They support the embodiment proposition that cognitive functions and representations can be grounded in bodily states via metaphorical associations. PMID:27672373

'Hard-to-reach' is a term used to describe those sub-groups of the population that may be difficult to reach or involve in research or public health programmes. Application of a single term to call these sub-sections of populations implies a homogeneity within distinct groups, which does not necessarily exist. Different sampling techniques were introduced so far to recruit hard-to-reach populations. In this article, we have reviewed a range of ap-proaches that have been used to widen participation in studies. We performed a Pubmed and Google search for relevant English language articles using the keywords and phrases: (hard-to-reach AND population* OR sampl*), (hidden AND population* OR sample*) and ("hard to reach" AND population* OR sample*) and a consul-tation of the retrieved articles' bibliographies to extract empirical evidence from publications that discussed or examined the use of sampling techniques to recruit hidden or hard-to-reach populations in health studies. Reviewing the literature has identified a range of techniques to recruit hard-to-reach populations, including snowball sampling, respondent-driven sampling (RDS), indigenous field worker sampling (IFWS), facility-based sampling (FBS), targeted sampling (TS), time-location (space) sampling (TLS), conventional cluster sampling (CCS) and capture re-capture sampling (CR). The degree of compliance with a study by a certain 'hard-to-reach' group de-pends on the characteristics of that group, recruitment technique used and the subject of inter-est. Irrespective of potential advantages or limitations of the recruitment techniques reviewed, their successful use depends mainly upon our knowledge about specific characteristics of the target populations. Thus in line with attempts to expand the current boundaries of our know-ledge about recruitment techniques in health studies and their applications in varying situa-tions, we should also focus on possibly all contributing factors which may have an impact on

Full Text Available Cheeses as ready-to-eat food should be considered as a potential source of foodborne pathogens, primarily Listeria monocytogenes. The aim of present study was to determine the microbiological quality of soft, semi-hard and hard cheeses during the shelf-life, with particular reference to L. monocytogenes. Five types of cheeses were sampled at different timepoints during the cold storage and analyzed for presence of Salmonella and L. monocytogenes, as well as lactic acid bacteria, Escherichia coli, coagulase-positive staphylococci, yeasts, molds, sulfite-reducing clostridia and L. monocytogenes counts. Water activity, pH and NaCl content were monitored in order to evaluate the possibility of L. monocytogenes growth. Challenge test for L. monocytogenes was performed in soft whey cheese, to determine the growth potential of pathogen during the shelf-life of product. All analyzed cheeses were compliant with microbiological criteria during the shelf-life. In soft cheeses, lactic acid bacteria increased in the course of the shelf-life period (1.2-2.6 log increase, while in semi-hard and hard cheeses it decreased (1.6 and 5.2 log decrease, respectively. Soft cheeses support the growth of L. monocytogenes according to determined pH values (5.8-6.5, water activity (0.99-0.94, and NaCl content (0.3-1.2%. Challenge test showed that L. monocytogenes growth potential in selected soft cheese was 0.43 log10 cfu/g during 8 days at 4°C. Water activity in semi-hard and hard cheeses was a limiting factor for Listeria growth during the shelf-life. Soft, semi-hard and hard cheeses were microbiologically stable during their defined shelf-life. Good manufacturing and hygienic practices must be strictly followed in the production of soft cheeses as Listeria-supporting food and be focused on preventing (recontamination.

Analytical Modeling of Hard-Coating Cantilever Composite Plate considering the Material Nonlinearity of Hard Coating

Directory of Open Access Journals (Sweden)

Wei Sun

2015-01-01

Full Text Available Due to the material nonlinearity of hard coating, the coated structure produces the nonlinear dynamical behaviors of variable stiffness and damping, which make the modeling of hard-coating composite structure become a challenging task. In this study, the polynomial was adopted to characterize this material nonlinearity and an analytical modeling method was developed for the hard-coating composite plate. Firstly, to relate the hard-coating material parameters obtained by test and the analytical model, the expression of equivalent strain of composite plate was derived. Then, the analytical model of hard-coating composite plate was created by energy method considering the material nonlinearity of hard coating. Next, using the Newton-Raphson method to solve the vibration response and resonant frequencies of composite plate and a specific calculation procedure was also proposed. Finally, a cantilever plate coated with MgO + Al2O3 hard coating was chosen as study case; the vibration response and resonant frequencies of composite plate were calculated using the proposed method. The calculation results were compared with the experiment and general linear calculation, and the correctness of the created model was verified. The study shows the proposed method can still maintain an acceptable precision when the material nonlinearity of hard coating is stronger.

2016-01-01

While the recent Coalition government committed to some initiatives supporting the role of parents, relationships and the early years, there remains a lack of focus on fathers as a distinct policy area. This is reflected at local government level, as lead professionals for young fathers are rare and data on the number of young fathers in each local area are not routinely collected. Barnardo's was funded by the Department for Education in 2012, as part of the Family Strategic Partnership, to highlight the needs and experiences of young fathers in England, and the joint role of statutory and voluntary services in supporting them (fully reported by Barnardo's in Cundy, 2012). Based on selected case studies drawn from research and a range of practice organisations, this article presents the journeys of five young fathers and their experience of maternity services, children's centres, schools, housing services and the secure estate.

The radiation hardness of commercial Floating Gate 256K E 2 PROMs from a single diffusion lot was observed to vary between 5 to 25 krad(Si) when irradiated at a low dose rate of 64 mrad(Si)/s. Additional variations in E 2 PROM hardness were found to depend on bias condition and failure mode (i.e., inability to read or write the memory), as well as the foundry at which the part was manufactured. This variability is related to system requirements, and it is shown that hardness level and variability affect the allowable mode of operation for E 2 PROMs in space applications. The radiation hardness of commercial 1-Mbit CMOS SRAMs from Micron, Hitachi, and Sony irradiated at 147 rad(Si)/s was approximately 12, 13, and 19 krad(Si), respectively. These failure levels appear to be related to increases in leakage current during irradiation. Hardness of SRAMs from each manufacturer varied by less than 20%, but differences between manufacturers are significant. The Qualified Manufacturer's List approach to radiation hardness assurance is suggested as a way to reduce variability and to improve the hardness level of commercial technologies

Long Day's journey into Night may seem a strange starting place for a feminist analysis of modernism and post-modernism. Yet even the most conservative criticism reads this play as an enactment and embodiment of loss, specifically loss of the mother. That loss is rarely seen in the context of a more general "loss", a cultural loss of legitimacy and authenticity, endemic in and enabling modernism, articulated as "disinheritance" by an Other "coded as feminine."

The "Journeys in Film" project brings important films and documentaries ("The Martian," "Hidden Figures," "River of Gold" and others) and curriculum-based, educational support activities to the classroom. Faculty from the University of New Hampshire, in partnership with selected local middle and high school teachers, developed a STEM Lesson Plan for Journeys in Film" focused on the soon-to-released documentary "River of Gold" which highlights tropical deforestation and illegal gold mining activities in the Peruvian jungles of the Amazon Basin. Using film clips (the Trailer) from the movie and the Lesson Plan, this approach allows pre-college students to learn how to use "Google Earth" to monitor chang-over-time and to quantify the areas of deforestation and mining using multi-date NOAA/USGS Landsat Thematic Mapper and ESA Copernicus satellite data. This approach will allow students to dconduct authentic hands-on science and mathematics to address a wide range of social and environmental issues associated with tropical deforestation in Peru.

The Pilgram's Progress: Reflections on the journey building Australia's solid earth information infrastructure (Invited)

Science.gov (United States)

Woodcock, R.

2013-12-01

Australia's AuScope provides world class research infrastructure as a framework for understanding the structure and evolution of the Australian continent. Since it conception in 2005, Data Scientists have led the Grid and Interoperability component of AuScope. The AuScope Grid is responsible for the effective management, curation, preservation and analysis of earth science data across the many organisations collaborating in AuScope. During this journey much was learned about technology and architectures but even more about organisations and people, and the role of Data Scientists in the science ecosystem. With the AuScope Grid now in operation and resulting techniques and technologies now underpinning Australian Government initiatives in solid earth and environmental information, it is beneficial to reflect upon the journey and observe what has been learned in order to make data science routine. The role of the Data Scientist is a hybrid one, of not quite belonging and yet highly valued. With the skills to support domain scientists with data and computational needs and communicate across domains, yet not quite able to do the domain science itself. A bridge between two worlds, there is tremendous satisfaction from a job well done, but paradoxically it is also best when it is unnoticeable. In the years since AuScope started much has changed for the Data Scientist. Initially misunderstood, Data Scientists are now a recognisable part of the science landscape in Australia. Whilst the rewards and incentives are still catching up, there is wealth of knowledge on the technical and soft skills required and recognition of the need for Data Scientists. These will be shared from the AuScope journey so other pilgrims may progress well.

Science.gov (United States)

Arima, Yoshitaka

2017-10-01

For developing a hardness multipoint measurement system for understanding hardness distribution on biological body surfaces, we investigated the spring strength of the contact portion main axis of a biological tissue hardness meter (product name: PEK). We measured the hardness of three-layered sheets of six types of gel sheets (90 mm × 60 mm × 6 mm) constituting the acupuncture practice pads, with PEK measurements of 1.96 N, 2.94 N, 3.92 N, 4.90 N, 5.88 N, 6.86 N, 7.84 N, 8.82 N, and 9.81 N of the main axis spring strength. We obtained measurements 10 times for the gel sheets and simultaneously measured the load using a digital scale. We measured the hardness distribution of induration embedded and breast cancer palpation models, with a main axis with 1.96 N, 4.90 N, and 9.81 N spring strengths, to create a two-dimensional Contour Fill Chart. Using 4.90 N spring strength, we could obtain measurement loads of ≤3.0 N, and the mean hardness was 5.14 mm. This was close to the median of the total measurement range 0.0-10.0 mm, making the measurement range the largest for this spring strength. We could image the induration of the induration-embedded model regardless of the spring strength. Overall, 4.90 N spring strength was best suited for imaging cancer in the breast cancer palpation model. Copyright © 2017. Published by Elsevier B.V.

Expanding Thurston maps

CERN Document Server

Bonk, Mario

2017-01-01

This monograph is devoted to the study of the dynamics of expanding Thurston maps under iteration. A Thurston map is a branched covering map on a two-dimensional topological sphere such that each critical point of the map has a finite orbit under iteration. It is called expanding if, roughly speaking, preimages of a fine open cover of the underlying sphere under iterates of the map become finer and finer as the order of the iterate increases. Every expanding Thurston map gives rise to a fractal space, called its visual sphere. Many dynamical properties of the map are encoded in the geometry of this visual sphere. For example, an expanding Thurston map is topologically conjugate to a rational map if and only if its visual sphere is quasisymmetrically equivalent to the Riemann sphere. This relation between dynamics and fractal geometry is the main focus for the investigations in this work.

Induced spherococcoid hard wheat

International Nuclear Information System (INIS)

Yanev, Sh.

1981-01-01

A mutant has been obtained - a spheroccocoid line -through irradiation of hard wheat seed with fast neutrons. It is distinguished by semispherical glumes and smaller grain; the plants have low stem with erect leaves but with shorter spikes and with lesser number of spikelets than those of the initial cultivar. Good productive tillering and resistance to lodging contributed to 23.5% higher yield. The line was superior to the standard and the initial cultivars by 14.2% as regards protein content, and by up to 22.8% - as to flour gluten. It has been successfully used in hybridization producing high-yielding hard wheat lines resistant to lodging, with good technological and other indicators. The possibility stated is of obtaining a spherococcoid mutant in tetraploid (hard) wheat out of the D-genome as well as its being suited to hard wheat breeding to enhance protein content, resistance to lodging, etc. (author)

Physics of Rotating and Expanding Black Hole Universe

Directory of Open Access Journals (Sweden)

Seshavatharam U. V. S.

2010-04-01

Full Text Available Throughout its journey universe follows strong gravity. By unifying general theory of relativity and quantum mechanics a simple derivation is given for rotating black hole’s temperature. It is shown that when the rotation speed approaches light speed temperature approaches Hawking’s black hole temperature. Applying this idea to the cosmic black hole it is noticed that there is “no cosmic temperature” if there is “no cosmic rotation”. Starting from the Planck scale it is assumed that- universe is a rotating and expanding black hole. Another key assumption is that at any time cosmic black hole rotates with light speed. For this cosmic sphere as a whole while in light speed rotation “rate of decrease” in temperature or “rate of increase” in cosmic red shift is a measure of “rate of cosmic expansion”. Since 1992, measured CMBR data indicates that, present CMB is same in all directions equal to 2 : 726 K ; smooth to 1 part in 100,000 and there is no continuous decrease! This directly indicates that, at present rate of decrease in temperature is practically zero and rate of expansion is practically zero. Universe is isotropic and hence static and is rotating as a rigid sphere with light speed. At present galaxies are revolving with speeds proportional to their distances from the cosmic axis of rotation. If present CMBR temperature is 2 : 726 K, present value of obtained angular velocity is 2 : 17 10 Present cosmic mass density and cosmic time are fitted with a ln ( volume ratio parameter. Finally it can be suggested that dark matter and dark energy are ad-hoc and misleading concepts.

2TB hard disk drive

CERN Multimedia

This particular object was used up until 2012 in the Data Centre. It slots into one of the Disk Server trays. Hard disks were invented in the 1950s. They started as large disks up to 20 inches in diameter holding just a few megabytes (link is external). They were originally called "fixed disks" or "Winchesters" (a code name used for a popular IBM product). They later became known as "hard disks" to distinguish them from "floppy disks (link is external)." Hard disks have a hard platter that holds the magnetic medium, as opposed to the flexible plastic film found in tapes and floppies.

Journey to become a nurse leader mentor: past, present and future influences.

Science.gov (United States)

McCloughen, Andrea; O'Brien, Louise; Jackson, Debra

2014-12-01

Mentorship, often viewed as a central capacity of leadership, is acknowledged as influential in growing nurse leaders. Mentoring relationships are perceived as empowering connections offering a dynamic guided experience to promote growth and development in personal and professional life. A hermeneutic phenomenological approach informed by Heidegger and Gadamer was used to explore understandings and experiences of mentorship for nurse leadership by 13 Australian nurse leaders. We found that learning and transformation associated with becoming a nurse leader mentor was experienced as an enduring evolutionary process. Participants' life journeys provided experiences that developed their understandings and established their personal identity as a leader and mentor. We considered the journey motif in terms of its inextricable connection with lived time and used Heidegger's ecstasies of temporality as a lens to understand how the temporal dimensions of past, present and future influenced and shaped the development of nurse leader mentors. We found that our temporal existence influences interpretation of ourselves and the world. Individuals can benefit from multiple separate mentoring interludes, with different mentors, over a lifetime. For some nurses, becoming a leader and mentor is a lifelong transformative process that grows from diverse experience and influential role modelling rather than formal instruction. © 2013 John Wiley & Sons Ltd.

A roadmap to peace. Journey metaphors in political speeches on the Middle East peace process

Assunta Caruso

2014-07-01

Full Text Available Abstract – This paper investigates the metaphorical conceptualization of peace by former leaders George W. Bush, Ariel Sharon, and Mahmoud Abbas. Specifically, it examines how peace/the peace process is conceptualized via metaphors through the notion of JOURNEY and MOVEMENT. The corpus in this study comprises twenty speeches given by the three politicians over a four-year period (2002-2005. The corpus data is analyzed using a combination of different methods. The tools are mainly Conceptual Metaphor Theory (Lakoff and Johnson 1980, the MIPVU procedure (Steen et al. 2010, and Critical Metaphor Analysis (Charteris-Black 2004. Findings reveal that JOURNEY metaphors are a vital and common part of the three politicians’ political discourse. Overall, there are very few metaphors for peace unique to the individual politicians. The main differences observed lie not in which metaphors are used, but in what aspects of peace or the peace process they are used to highlight.Keywords: metaphor identification, conceptual metaphor, Critical Metaphor Analysis, political discourse, peace.

Wu, Wan-Ru; Chung, Ue-Lin; Chang, Sophia C N

2007-06-01

The purpose of this qualitative research study was to explore the preoperative through postoperative phase experience of women who had undergone augmentation mammaplasty. Nine women undergoing augmentation mammaplasty were selected by purposive sampling and interviewed using semi- structured, open-ended interview guidelines. Researchers used Symbolic interactionism to frame their overall perspective and analyzed data with the content analysis method. Rigors of data analysis were adopted credibility, transferability, dependability and confirmability proposed by Guba and Lincoln. The main theme of living experience of women who received augmentation mammaplasty could be summarized as "a journey to restore self-confidence". The categories identified within this journey included: (1) the invisible standards of breast beauty; (2) Taking courageous action to make changes; (3) conflicts between the natural and artificial. The above findings provided initial qualitative data from Taiwanese women's perspective. By better understanding their experience, nurses can become increasingly sensitive to patients' psychosocial adjustment and provide prudential nursing care.

Using measures to guide the continuous improvement journey: a partnership between quality assurance and toxicology.

Gentry, P E; Sites, D L

It has been said that you cannot improve what you cannot measure. At Eli Lilly and Company, measurement is one of the five pillars of Total Quality. Quality Assurance and Toxicology have partnered in the use of measures to drive improvements in both areas. Quality Assurance and Toxicology have embarked on a journey in Total Quality to achieve customer satisfaction and drive continuous improvement. Measurement in the research and development world has traditionally not been well received. Contrary to popular belief, we have found that many processes can be measured in the research and development environment. Measurement is critical to the continuous improvement of processes because improvements are made using data. In Quality Assurance and Toxicology, the initial measures were put in place to gather baseline data. As we learned from our measures, we customized them to align with all of our processes. This article describes the journey of measuring Quality Assurance and Toxicology, including highlights of implementation strategies and lessons learned along the way.

Kambagowni, Venkatasubbaiah; Chitla, Raju; Challa, Suresh

2018-05-01

In the present manufacturing industries hardened steels are most widely used in the applications like tool design and mould design. It enhances the application range of hard turning of hardened steels in manufacturing industries. This study discusses the impact of workpiece hardness, feed and depth of cut on Arithmetic mean roughness (Ra), root mean square roughness (Rq), mean depth of roughness (Rz) and total roughness (Rt) during the hard turning. Experiments have been planned according to the Box-Behnken design and conducted on hardened AISI4340 steel at 45, 50 and 55 HRC with wiper ceramic cutting inserts. Cutting speed is kept constant during this study. The analysis of variance was used to determine the effects of the machining parameters. 3-D response surface plots drawn based on RSM were utilized to set up the input-output relationships. The results indicated that the feed rate has the most significant parameter for Ra, Rq and Rz and hardness has the most critical parameter for the Rt. Further, hardness shows its influence over all the surface roughness characteristics.

Ambivalent journeys of hope: embryonic stem cell therapy in a clinic in India.

Science.gov (United States)

Prasad, Amit

2015-03-01

Stem cell therapy in non-Western countries such as India has received a lot of attention. Apart from media reports, there are a number of social science analyses of stem cell policy, therapy, and research, their ethical implications, and impact of advertising on patients. Nevertheless, in the media reports as well as in academic studies, experiences of patients, who undertake overseas journeys for stem cell therapy, have largely been either ignored or presented reductively, often as a "false hope." In this article, I analyze the experiences of patients and their "journeys of hope" to NuTech Mediworld, an embryonic stem cell therapy clinic in New Delhi, India. My analysis, which draws on my observations in the clinic and patients' experiences, instead of seeking to adjudicate whether embryonic stem cell therapy in clinics such as NuTech is right or wrong, true or false, focuses on how patients navigate and contest these concerns. I utilize Gilles Deleuze and Felix Guattari's "concepts," lines of flight and deterritorialization, to highlight how embryonic stem cell therapy's "political economy of hope" embodies deterritorialization of several "regimes of truth" and how these deterritorializations impact patients' experiences. © The Author(s) 2014.

Three Women’s Educational Doctoral Program Experiences: A Case Study of Performances and Journeys

Directory of Open Access Journals (Sweden)

Erin Goodykoontz

2011-07-01

Full Text Available Three academic women joined to write this piece to explore individual doctoral program experiences and to establish common understandings. They collectively analyzed their experiences using the conceptual approach of doctoral program performances and journeys. This case study shares their experiences within the conceptual approach through emerging themes. The common understandings developed herein about doctoral education based on these themes are also shared. The broader contributions of the three women’s work are two-fold. First, the entire case study provides a way to view, discuss, and consider women’s doctoral education pluralistically. Secondly, perhaps readers of this piece will recognize that individual and common understandings with others are a way to develop professional knowledge as academics. Further, readers of this piece might be able to relate more deeply to their own and others’ unique doctoral program experiences through the lens of performances or journeys. Some of these connections might be based on the overarching framework, while others might be specific to the shared women’s experiences.

Approaches to Recruiting ‘Hard-To-Reach’ Populations into Re­search: A Review of the Literature

Science.gov (United States)

Shaghaghi, Abdolreza; Bhopal, Raj S; Sheikh, Aziz

2011-01-01

Background: ‘Hard-to-reach’ is a term used to describe those sub-groups of the population that may be difficult to reach or involve in research or public health programmes. Application of a single term to call these sub-sections of populations implies a homogeneity within distinct groups, which does not necessarily exist. Different sampling techniques were introduced so far to recruit hard-to-reach populations. In this article, we have reviewed a range of ap­proaches that have been used to widen participation in studies. Methods: We performed a Pubmed and Google search for relevant English language articles using the keywords and phrases: (hard-to-reach AND population* OR sampl*), (hidden AND population* OR sample*) and (“hard to reach” AND population* OR sample*) and a consul­tation of the retrieved articles’ bibliographies to extract empirical evidence from publications that discussed or examined the use of sampling techniques to recruit hidden or hard-to-reach populations in health studies. Results: Reviewing the literature has identified a range of techniques to recruit hard-to-reach populations, including snowball sampling, respondent-driven sampling (RDS), indigenous field worker sampling (IFWS), facility-based sampling (FBS), targeted sampling (TS), time-location (space) sampling (TLS), conventional cluster sampling (CCS) and capture re-capture sampling (CR). Conclusion: The degree of compliance with a study by a certain ‘hard-to-reach’ group de­pends on the characteristics of that group, recruitment technique used and the subject of inter­est. Irrespective of potential advantages or limitations of the recruitment techniques reviewed, their successful use depends mainly upon our knowledge about specific characteristics of the target populations. Thus in line with attempts to expand the current boundaries of our know­ledge about recruitment techniques in health studies and their applications in varying situa­tions, we should also focus on

Goreczny, Sebastian; Qureshi, Shakeel A; Rosenthal, Eric; Krasemann, Thomas; Nassar, Mohamed S; Anderson, David R; Morgan, Gareth J

2017-07-01

We aimed to compare the procedural and mid-term performance of a specifically designed self-expanding stent with balloon-expandable stents in patients undergoing hybrid palliation for hypoplastic left heart syndrome and its variants. The lack of specifically designed stents has led to off-label use of coronary, biliary, or peripheral stents in the neonatal ductus arteriosus. Recently, a self-expanding stent, specifically designed for use in hypoplastic left heart syndrome, has become available. We carried out a retrospective cohort comparison of 69 neonates who underwent hybrid ductal stenting with balloon-expandable and self-expanding stents from December, 2005 to July, 2014. In total, 43 balloon-expandable stents were implanted in 41 neonates and more recently 47 self-expanding stents in 28 neonates. In the balloon-expandable stents group, stent-related complications occurred in nine patients (22%), compared with one patient in the self-expanding stent group (4%). During follow-up, percutaneous re-intervention related to the ductal stent was performed in five patients (17%) in the balloon-expandable stent group and seven patients (28%) in self-expanding stents group. Hybrid ductal stenting with self-expanding stents produced favourable results when compared with the results obtained with balloon-expandable stents. Immediate additional interventions and follow-up re-interventions were similar in both groups with complications more common in those with balloon-expandable stents.

More Than a Destination: Contraceptive Decision Making as a Journey.

Science.gov (United States)

Downey, Margaret Mary; Arteaga, Stephanie; Villaseñor, Elodia; Gomez, Anu Manchikanti

Contraceptive use is widely recognized as a means of reducing adverse health-related outcomes. However, dominant paradigms of contraceptive counseling may rely on a narrow definition of "evidence" (i.e., scientifically accurate but exclusive of individual women's experiences). Given increased enthusiasm for long-acting, reversible contraceptive methods, such paradigms may reinforce counseling that overprivileges effectiveness, particularly for groups considered at high risk of unintended pregnancy. This study investigates where and how women's experiences fit into the definition of evidence these counseling protocols use. Using a qualitative approach, this analysis draws on semistructured interviews with 38 young (ages 18-24) Black and Latina women. We use a qualitative content analysis approach, with coding categories derived directly from the textual data. Our analysis suggests that contraceptive decision making is an iterative, relational, reflective journey. Throughout contraceptive histories, participants described experiences evolving to create a foundation from which decision-making power was drawn. The same contraceptive-related decisions were revisited repeatedly, with knowledge accrued along the way. The cumulative experience of using, assigning meanings to, and developing values around contraception meant that young women experienced contraceptive decision making as a dynamic process. This journey creates a rich body of evidence that informs contraceptive decision making. To provide appropriate, acceptable, patient-centered family planning care, providers must engage with evidence grounded in women's expertise on their contraceptive use in addition to medically accurate data on method effectiveness, side effects, and contraindications.

A Journey to Wholeness Through Tai Chi

Science.gov (United States)

Al-Turki, Faiza

Healing is a multifaceted venture. Whereas many traditional cultures see healing as a journey that, by necessity, combines body, mind, and spirit, today's Western society frequently divides healing, relegating its parts to various experts--body to physicians, mind to psychologists, spirit to religions. Employing heuristic and alchemical hermeneutic methodologies, this thesis explores tai chi as a healing tool that bridges that division, exploring the following question: is it possible that the connection of body, mind, and spirit offered by tai chi is the very mechanism by which it facilitates healing? The cultural and historical context of tai chi is introduced, as well as research showing various Western views. A heuristic approach offers personal examples of the use of tai chi as a process partner, while a depth psychological lens informs the use of tai chi principles to guide moments of self-exploration and transformation in a therapeutic way.

There is little information in the literature describing how students learn qualitative research. This article describes an approach to learning that is based on the pedagogical approach of Dinkins' Socratic-Hermeneutic Shared Inquiry. This approach integrates shared dialog as an essential aspect of learning. The qualitative pedagogy described in this article focused on three questions: What is knowing in qualitative research? How do we come to know qualitative research? What can we do with qualitative research? Students learned the basics of qualitative research within a context that fostered interpretive inquiry. In this way, the course framework mirrored the combination of interviewing, storytelling, and journeying toward understanding that constitute qualitative research. © 2013.

Full Text Available Anastasia’s Journeys was a temporary exhibition in the Australian History Museum, Macquarie University, Australia. Developed from the oral history of a post-World War Two Russian immigrant who survived Stalin’s policies of forced collectivisation and engineered famine, the display communicated primarily through audio tracks, supported by text panels and objects. This article articulates the creative tensions between theory and practice of public history which were encountered when planning the target audience, content, and design of the exhibition. It describes the process by which the oral history was placed at the centre of the presentation while objects were used both to illustrate changing social situations and introduce an opposing interpretation. The attributes of the oral history which made it suitable for an audio presentation are then discussed.

The concept of hardness as a structure-sensitive characteristic of a material is considered. It is shown that in conditions of a decreasing stress field under the inventor the hardness function is determined by the average distance, Lsub(a), between the stops (fixed and sessile dislocations, segregation particles, etc.). In the general case, Lsub(a) depends on the size of the impression and explains the great diversity of hardness functions. The concept of average true deformation rate on depression is introduced

Hard spectator interactions in B {yields} {pi}{pi} at order {alpha}{sup 2}{sub s}

In the present thesis I discuss the hard spectator interaction amplitude in B {yields} {pi}{pi} at NLO i.e. at O({alpha}{sup 2}{sub s}). This special part of the amplitude, whose LO starts at O({alpha}{sub s}), is defined in the framework of QCD factorization. QCD factorization allows to separate the short- and the long-distance physics in leading power in an expansion in {lambda}{sub QCD}/m{sub b}, where the short-distance physics can be calculated in a perturbative expansion in {alpha}{sub s}. Compared to other parts of the amplitude hard spectator interactions are formally enhanced by the hard collinear scale {radical}({lambda}{sub QCD}m{sub b}), which occurs next to the mb-scale and leads to an enhancement of {alpha}{sub s}. From a technical point of view the main challenges of this calculation are due to the fact that we have to deal with Feynman integrals that come with up to five external legs and with three independent ratios of scales. These Feynman integrals have to be expanded in powers of {delta}{sub QCD}/m{sub b}. I discuss integration by parts identities to reduce the number of master integrals and differential equations techniques to get their power expansions. A concrete implementation of integration by parts identities in a computer algebra system is given in the appendix. Finally I discuss numerical issues like scale dependence of the amplitudes and branching ratios. It turns out that the NLO contributions of the hard spectator interactions are important but small enough for perturbation theory to be valid. (orig.)

The hardness of the hydroxyapatite-titania bilayer coatings by microindentation and nanoindentation testing

SIDANE, Djahida; KHIREDDINE, Hafit; YALA, Sabeha

The aim of this paper is to investigate the effect of the addition of titania (TiO2) inner-layer on the morphological and mechanical properties of hydroxyapatite (HAP) bioceramic coatings deposited on 316L stainless steel (316L SS) by sol-gel method in order to improve the properties of hydroxyapatite and expand its clinical application. The addition of TiO2 as sublayer of a hydroxyapatite coating results in changes in surface morphology as well as an increase of the microhardness. The deposition of the inner-layer provides the formation of new types of hydroxyapatite coatings at the same condition of annealing. This represents an advantage for the various applications of the hydroxyapatite bioceramic in the medical field. Classical hardness measurements conducted on the coated systems under the same indentation load (10g) indicated that the microhardness of the HAP coating is improved by the addition of TiO2 inner-layer on the 316L stainless steel substrate. The hardness values obtained from both classical tests in microindentation and the continuous stiffness measurement mode in nanoindentation are slightly different. This is because nanoindentation is more sensitive to the surface roughness and the influence of defects that could be present into the material. Moreover, nanoindentation is the most useful method to separate the contribution of each layer in the bilayer coatings. In this study, the hardness is comparable with those reported previously for pure HAP ceramics (1.0-5.5 GPa) which are close to the properties of natural teeth.

The Religious Quest As Transformative Journey: Interspiritual Religious Belonging And The Problem Of Religious Depth

Directory of Open Access Journals (Sweden)

McEntee Rory

2017-11-01

Full Text Available As scholars and the public grope towards understanding emergent forms of religiosity (multiple-religious belonging, spiritual but not religious, interspirituality, notions of discernment, religious depth, and spiritual practice figure prominently in defining and assessing these forms. Some form of commitment to a particular religious tradition is often considered the most important factor in the discernment of religious depth, while “spiritual but not religious” is often seen as the amorphous searching or the drifting whims of an immature ego. I will argue, however, that failing to take into account the most mature forms of emerging religiosity is bound to miss important developments, just as similar methodologies would for traditional religions. Further, I point out problems with correlating religious depth with belonging to a particular religious tradition, and offer an alternate way to conceive of religious depth. In doing so I develop the concept of the religious quest as transformative journey, allowing for a more capacious understanding of religious consciousness. I then introduce interspiritual religious belonging, contrasting it with certain understandings of “multiple-religious” belonging, and providing mature examples of its embodiment. Finally, utilizing new surveys from Pew and PPRI showing accelerating growth among the “spiritual but not religious” and “religiously unaffiliated”-as well as expanding religious and racial diversity within the United States-I briefly reference potential political ramifications the interspiritual movement might have, and address the importance of developing mature theological perspectives from within it. It is my hope that the Theology Without Walls project can provide academic space for the latter.

Grenacher, Lars; Rohde, Stefan; Gaenger, Ellen; Deutsch, Jochen; Kauffmann, Guenter W.; Richter, Goetz M.

2006-01-01

The objective was to compare the radial strength and expansile precision of self-expanding stents and balloon-expandable stents in a human cadaver bifurcation model. Seven different self-expanding (LUMINEXX, JOSTENT SelfX, JOSTENT SelfX hrf, Sinus-Repo, Sinus SuperFlex, Easy Wallstent, SMART) and four different balloon-expandable stent models (Palmaz, Sinus Stent, SAXX Medium, JOSTENT peripheral), each type 10 stents (total n = 110 stents) were implanted into the common iliac arteries of human cadaver corpses. The maximum stent diameter was 10 mm for all models. After stent implantation, the specimens were filled with silicone caoutchouc. After 24 h, the vascular walls including the stents were removed from the hardened casts. Diameters were taken and the weight of the cast cylinders was measured in air and in purified water to calculate the volume of the bodies (according to Archimedes Law) as a relative but precise degree for the radial strength of the implanted stents. The cylindrical casts of the self-expanding stents showed lower mean diameters (8.2 ± 1.0 mm) and mean volumes (0.60 ± 0.14 ml/cm) than in the balloon-expandable stent group (10.1 ± 0.3 mm and 0.71 ± 0.04 ml/cm, respectively; p < 0.01). The nominal maximum diameter of 10 mm was not achieved in any of the self-expanding stents, but this was achieved in more than 70% (29/40) of the balloon-expandable stent specimens (p < 0.05). The variation between achieved volumes was significantly larger in self-expanding (range: 0.23-0.78 ml/cm) than in balloon-expandable stents (range: 0.66-0.81 ml/cm; p < 0.05). Self-expanding stents presented considerably lower radial expansion force and lower degree of precision than balloon-expandable stents

Micro-hardness of non-irradiated uranium dioxide

Kim, Sung-Sik; Takagi, Osamu; Obata, Naomi; Kirihara, Tomoo.

1983-01-01

In order to obtain the optimum conditions for micro-hardness measurements of sintered UO 2 , two kinds of hardness tests (Vickers and Knoop) were examined with non-irradiated UO 2 of 2.5 and 5 μm in grain size. The hardness values were obtained as a function of the applied load in the load range of 25 -- 1,000 g. In the Vickers test, cracks were generated around the periphery of an indentation even at lower load of 50 g, which means the Vickers hardness is not suitable for UO 2 specimens. In the Knoop test, three stages of load dependence were observed for sintered pellet as well as for a single crystal by Bates. Load dependence of Knoop hardness and crack formation were discussed. In the range of applied load around 70 -- 100 g there were plateau region where hardness values were nearly unchanged and did not contain any cracks in the indentation. The plateau region represents a hardness of a specimen. From a comparison between the hardness values of 2.5 μm and those of 5 μm UO 2 , it was approved that the degree of sintering controls the hardness in the plateau region. (author)

[Brazilian scientists visit the Amazon: The scientific journeys of Oswaldo Cruz and Carlos Chagas (1910-13)].

Schweickardt, Júlio César; Lima, Nísia Trindade

2007-12-01

The article analyzes reports from two scientific journeys into the Amazon conducted by the Instituto Oswaldo Cruz, in 1910 and 1913, under the leadership of Oswaldo Cruz and Carlos Chagas, respectively. These reports contributed to the construction of representations and images of the region. Field observations not only provided data for the study and control of tropical diseases but also had a hand in the movement to denounce the serious sanitation conditions under which rubber workers labored. Journeys through the Amazon valley put the scientists in direct contact with the environment and with sick populations; these travels also made them face the huge challenges of learning about malaria and trying to control it. Analyses of these reports are part of studies on 'portraits of Brazil', which raise issues within the history of public health policies. In this endeavor to reveal the process by which scientific records are constructed, we worked with primary sources,from manuscripts to official texts.

Physics of Rotating and Expanding Black Hole Universe

Directory of Open Access Journals (Sweden)

Seshavatharam U. V. S.

2010-04-01

Full Text Available Throughout its journey universe follows strong gravity. By unifying general theory of relativity and quantum mechanics a simple derivation is given for rotating black hole's temperature. It is shown that when the rotation speed approaches light speed temperature approaches Hawking's black hole temperature. Applying this idea to the cosmic black hole it is noticed that there is "no cosmic temperature" if there is "no cosmic rotation". Starting from the Planck scale it is assumed that universe is a rotating and expanding black hole. Another key assumption is that at any time cosmic black hole rotates with light speed. For this cosmic sphere as a whole while in light speed rotation "rate of decrease" in temperature or "rate of increase" in cosmic red shift is a measure of "rate of cosmic expansion". Since 1992, measured CMBR data indicates that, present CMB is same in all directions equal to $2.726^circ$ K, smooth to 1 part in 100,000 and there is no continuous decrease! This directly indicates that, at present rate of decrease in temperature is practically zero and rate of expansion is practically zero. Universe is isotropic and hence static and is rotating as a rigid sphere with light speed. At present galaxies are revolving with speeds proportional to their distances from the cosmic axis of rotation. If present CMBR temperature is $2.726^circ$ K, present value of obtained angular velocity is $2.17 imes 10^{-18}$ rad/sec $cong$ 67 Km/sec$imes$Mpc. Present cosmic mass density and cosmic time are fitted with a $ln (volume ratio$ parameter. Finally it can be suggested that dark matter and dark energy are ad-hoc and misleading concepts.

Helping parents live with the hole in their heart: The role of health care providers and institutions in the bereaved parents' grief journeys.

Bereaved parents experience significant psychosocial and health sequelae, suggesting that this population may benefit from the ongoing extension of support and resources throughout the grief journey. The interaction of hospital staff with patients and families at the end of a child's life and after death profoundly affects parental grief, offering a unique opportunity for the medical community to positively impact the bereavement experience. The current study was conducted to explore the role of the health care team and medical institutions in the grief journeys of parents whose child died a cancer-related death. Eleven bereaved parents participated in 2 focus groups. Responses to each of the 3 main prompts were coded and analyzed independently using semantic content analysis techniques. Four main concepts were identified within the parental narratives, including the importance of strong and ongoing relationships between providers and bereaved families, the importance of high-quality communication, the effect of negative experiences between providers and families on parental grief, and the importance of the institution's role in the grief journeys of bereaved parents. Bereaved parents consistently identified the critical role played by medical staff and medical institutions throughout the grief journey. Key components of bereavement support identified by parents should serve to guide the actions of providers as well as provide a template for the development of a comprehensive bereavement program within an institution.

Lacanian Orders in Eugene O’Neill’s Long Day’s Journey into Night

Directory of Open Access Journals (Sweden)

Sima Farshid

2013-03-01

Full Text Available This paper presents a Lacanian reading of Eugene O’Neill’s Long Day’s Journey into Night (1941 by drawing on the psychic orders the well-known French psychoanalyst Jacques Lacan has propounded. He holds that human psyche is formed of three orders (the Imaginary, the Symbolic and the Real which mold the unconscious mind and motivate human actions and reactions. He also argues that the Other has an immense impact on the formation of psychic orders, especially the Symbolic, and hence on one’s identity. The present article attempts to investigate the three orders of the characters O’Neill has portrayed in Long Day’s Journey into Night, besides the role of the Other in the formation of those orders. The reactions of these characters to the outside world are regarded here as the outer presentation of their troubled mind. It is also discussed that the mental and physical problems and disorders of these characters, such as their addiction to alcohol and drugs, are the outcome of their repressed desires which have remained unfulfilled because of the rules defined and imposed on them by the Other – hence the frustrating sense of lack observed in all four characters.

Brokers, consumers and the internet: how North American consumers navigate their infertility journeys.

Science.gov (United States)

Speier, Amy R

2011-11-01

North Americans who suffer infertility often reach an end to treatment options at home, whether it is due to a lack of egg donors in Canada or the high cost of treatment in the USA. Patients navigate their way onto the internet, seeking support and other options. As women and couples 'do the research' online, they conduct endless Google searches, come across IVF brokers, join support groups, read blogs and meet others on the road of infertility. This paper considers the journeys that North American patients make to clinics in Moravia, Czech Republic. Along these travels, patients engage with support groups, other patients, IVF brokers and clinic co-ordinators. Since the distance travelled between North America and Europe is extensive, reproductive travels may be arranged by clinical staff, travel brokers and patients. Acting as consumers, North Americans make different 'choices' along their journeys – the use of a broker, if and when they should join online communities, which clinic to visit and where to stay. This study focuses on the question of how patient choices often determine the success of brokers and clinics, thus influencing the structure of cross-border reproductive care in the Czech Republic.

Thermal spray coatings replace hard chrome

International Nuclear Information System (INIS)

Schroeder, M.; Unger, R.

1997-01-01

Hard chrome plating provides good wear and erosion resistance, as well as good corrosion protection and fine surface finishes. Until a few years ago, it could also be applied at a reasonable cost. However, because of the many environmental and financial sanctions that have been imposed on the process over the past several years, cost has been on a consistent upward trend, and is projected to continue to escalate. Therefore, it is very important to find a coating or a process that offers the same characteristics as hard chrome plating, but without the consequent risks. This article lists the benefits and limitations of hard chrome plating, and describes the performance of two thermal spray coatings (tungsten carbide and chromium carbide) that compared favorably with hard chrome plating in a series of tests. It also lists three criteria to determine whether plasma spray or hard chrome plating should be selected

Full Text Available We previously developed and validated a vortexing-sonication technique for detection of biofilm bacteria on the surface of explanted prosthetic joints. Herein, we evaluated this technique for diagnosis of infected breast tissue expanders and used it to assess colonization of breast tissue expanders. From April 2008 to December 2011, we studied 328 breast tissue expanders at Mayo Clinic, Rochester, MN, USA. Of seven clinically infected breast tissue expanders, six (85.7% had positive cultures, one of which grew Propionibacterium species. Fifty-two of 321 breast tissue expanders (16.2%, 95% CI, 12.3–20.7% without clinical evidence of infection also had positive cultures, 45 growing Propionibacterium species and ten coagulase-negative staphylococci. While vortexing-sonication can detect clinically infected breast tissue expanders, 16 percent of breast tissue expanders appear to be asymptomatically colonized with normal skin flora, most commonly, Propionibacterium species.

Photon production in an expanding and chemically equilibrating gluon-enriched plasma

International Nuclear Information System (INIS)

Kaempfer, B.; Technische Univ. Dresden; Pavlenko, O.P.; AN Ukrainskoj SSR, Kiev

1993-12-01

Photon production in a longitudinally and transversely expanding gluon plasma with initially little quark admixture is considered. Chemical equilibration of quarks and gluons is followed by rate equations. The yields of hard photons with E ≥ 2 GeV are insensitive to chemical equilibration and depend mainly on the initial thermalized state. Medium-energy photons with E ∼ 1 GeV are more frequently produced in case of faster equilibration, despite of faster cooling. For an assumed fast equilibration we follow the evolution of matter through mixed and hadron phases. The transverse momentum kick, due to transverse expansion, of photons from hadron matter is shown to be reduced for an equation of state with reduced latent heat. The photon yield in the region E > 1 GeV from deconfined matter dominates for conditions, estimated to be achieved at RHIC, in case of a weakly first-order confinement transition. (orig.)

Hard-hard coupling assisted anomalous magnetoresistance effect in amine-ended single-molecule magnetic junction

Science.gov (United States)

Tang, Y.-H.; Lin, C.-J.; Chiang, K.-R.

2017-06-01

We proposed a single-molecule magnetic junction (SMMJ), composed of a dissociated amine-ended benzene sandwiched between two Co tip-like nanowires. To better simulate the break junction technique for real SMMJs, the first-principles calculation associated with the hard-hard coupling between a amine-linker and Co tip-atom is carried out for SMMJs with mechanical strain and under an external bias. We predict an anomalous magnetoresistance (MR) effect, including strain-induced sign reversal and bias-induced enhancement of the MR value, which is in sharp contrast to the normal MR effect in conventional magnetic tunnel junctions. The underlying mechanism is the interplay between four spin-polarized currents in parallel and anti-parallel magnetic configurations, originated from the pronounced spin-up transmission feature in the parallel case and spiky transmission peaks in other three spin-polarized channels. These intriguing findings may open a new arena in which magnetotransport and hard-hard coupling are closely coupled in SMMJs and can be dually controlled either via mechanical strain or by an external bias.

Affirmation through disability: one athlete's personal journey to the London Paralympic Games.

Science.gov (United States)

Kavanagh, Emma

2012-03-01

This article explores the personal narrative of a British Paralympic wheelchair tennis player who experienced a spinal cord injury (SCI) following a motorcycle accident in 2001 that left her paralysed from the waist down. The study responds to the call by Swain and French, among others, for alternative accounts of disability that demonstrate how life following impairment need not be empty and meaningless, but can actually reflect a positive, if different, social identity. This study draws upon life history data to investigate the journey of one athlete who has managed to achieve international sporting success following a life-changing accident. A pseudonym has not been used for this study as the athlete wanted to be named in the research account and for her story to be shared. A chronological approach was adopted to map the pre- and post-accident recovery process. The account examines life before the trauma, the impact of the accident, the process of rehabilitation and the journey to athletic accomplishment. Negative views of disability can be challenged if disability is viewed in the context of positive life narratives. The story of one Paralympian demonstrates how an 'ordinary' person has made the most of an extraordinary situation and become a world-class athlete. This paper demonstrates that in contrast to typical discourse in disability studies, becoming disabled or living with a disability need not be a tragedy but may on the contrary enhance life and lead to positive affirmation.

Thermodynamic equivalence between the Lennard-Jones and hard-core attractive Yukawa systems

International Nuclear Information System (INIS)

Kadiri, Y.; Albaki, R.; Bretonnet, J.L.

2008-01-01

The investigation of the thermodynamic properties of the Lennard-Jones (LJ) fluid is made by means of a system of particles interacting with a potential of hard-core plus attractive Yukawa tail (HCY). Due to the similarity between the LJ potential and the HCY potential in its overall form, it is worthwhile seeking to approximate the LJ potential in much the same way that the hard-sphere reference potential has been so used. The study consists in describing the thermodynamics of the LJ fluid in terms of the equivalent HCY system, whose the properties are known accurately, by means of mapping the thermodynamic quantities for the HCY potential parameters. The method is feasible owing to a convenient analytical expression of the Helmholtz free energy from the mean-spherical approximation expanded in power of the inverse temperature. Two different procedures are used to determine the parameters of the HCY potential as a function of the thermodynamic states: one is based on the simultaneous fits of pressure and internal energy of the LJ system and the other uses the concept of collision frequency. The reasonable homogeneity of the results in both procedures of mapping makes that the HCY potential is a very good reference system, whose the proposed theoretical expressions can be used confidently to predict the thermodynamic properties of more realistic potentials

The Leeb Hardness Test for Rock: An Updated Methodology and UCS Correlation

Science.gov (United States)

Corkum, A. G.; Asiri, Y.; El Naggar, H.; Kinakin, D.

2018-03-01

The Leeb hardness test (LHT with test value of L D ) is a rebound hardness test, originally developed for metals, that has been correlated with the Unconfined Compressive Strength (test value of σ c ) of rock by several authors. The tests can be carried out rapidly, conveniently and nondestructively on core and block samples or on rock outcrops. This makes the relatively small LHT device convenient for field tests. The present study compiles test data from literature sources and presents new laboratory testing carried out by the authors to develop a substantially expanded database with wide-ranging rock types. In addition, the number of impacts that should be averaged to comprise a "test result" was revisited along with the issue of test specimen size. Correlation for L D and σ c for various rock types is provided along with recommended testing methodology. The accuracy of correlated σ c estimates was assessed and reasonable correlations were observed between L D and σ c . The study findings show that LHT can be useful particularly for field estimation of σ c and offers a significant improvement over the conventional field estimation methods outlined by the ISRM (e.g., hammer blows). This test is rapid and simple, with relatively low equipment costs, and provides a reasonably accurate estimate of σ c .

Leadership as a Personal Journey: An Indigenous Perspective.

Science.gov (United States)

Doyle, Kerrie; Hungerford, Catherine

2015-05-01

Indigenous Australians have higher levels of mental illness, self-harm, suicide and substance abuse than non-Indigenous Australians, as well as more frequent contact with the criminal justice system. These indices point to the need for strong leadership to support Close the Gap programmes that have now been implemented across Australia. This article considers leadership as a journey of learning for Australian Indigenous leaders. Through the use of story, it is suggested that a situational leadership approach, incorporating the principles of mindfulness, provides the most appropriate framework for Indigenous leaders who work with Indigenous communities. Flexible approaches are needed to meet the needs of diverse Indigenous populations, and address the complex challenges involved, including lateral violence. Such flexibility will enable Indigenous leaders and communities to work together to achieve improvements in the health outcomes, not only for Indigenous Australians, but also for Indigenous populations worldwide.

Luger, Rosemary; Prudhomme, Debbie; Bullen, Ann; Pitt, Catherine; Geiger, Martha

2012-01-01

The purpose of this case study was to relate part of the journey to appropriate education for two young children with physical disabilities in a low socio-economic peri-urban informal settlement - or 'township' - in South Africa. The part of the on-going journey described here spanned four-and-a-half years and included the two children, their families, their teachers, their community and a small team of rehabilitation professionals working for a non-profit organisation in the area. The rehabilitation professionals' goals were to provide support for the children, their families, their current special care centre and the school(s) they would attend in the future. The steps from the special care centre, to a mainstream early childhood development (ECD) centre for both of them, and then on to (a) a school for learners with special educational needs (LSEN) for one child and (b) a mainstream primary school for the other, are described. Challenges encountered on the way included parental fears, community attitudes and physical accessibility. Practical outcomes included different placements for the two children with implications and recommendations for prioritised parent involvement, individual approaches, interdisciplinary and community-based collaborations. Recommendations are given for clinical contexts, curricula and policy matters; for research and for scaling up such a programme through community workers.

Isotropic-nematic transition in a mixture of hard spheres and hard spherocylinders: scaled particle theory description

Directory of Open Access Journals (Sweden)

M.F. Holovko

2017-12-01

Full Text Available The scaled particle theory is developed for the description of thermodynamical properties of a mixture of hard spheres and hard spherocylinders. Analytical expressions for free energy, pressure and chemical potentials are derived. From the minimization of free energy, a nonlinear integral equation for the orientational singlet distribution function is formulated. An isotropic-nematic phase transition in this mixture is investigated from the bifurcation analysis of this equation. It is shown that with an increase of concentration of hard spheres, the total packing fraction of a mixture on phase boundaries slightly increases. The obtained results are compared with computer simulations data.

Helium turbo-expander with an alternator

International Nuclear Information System (INIS)

Akiyama, Yoshitane

1980-01-01

Study was made on a helium turbo-expander, the heart of helium refrigerator systems, in order to develop a system which satisfies the required conditions. A helium turbo-expander with externally pressurized helium gas bearings at the temperature of liquid nitrogen and an alternator as a brake have been employed. The essential difference between a helium turbo-expander and a nitrogen turbo-expander was clarified. The gas bearing lubricated with nitrogen at room temperature and the gas bearing lubricated with helium at low temperature were tested. The flow rate of helium in a helium refrigerator for a large superconducting magnet is comparatively small, therefore a helium turbine must be small, but the standard for large turbine design can be applied to such small turbine. Using the alternator as a brake, the turbo-expander was easily controllable electrically. The prototype turbo-expander was made, and the liquefaction test with it and MHD power generation test were carried out. (Kako, I.)

Descriptive aspects of space on Guimarães Rosa's “A hora e vez de Augusto Matraga”: an initiation on journey

Directory of Open Access Journals (Sweden)

João Gomes da Silva Neto

2013-12-01

Full Text Available This paper focuses on some textual and discursive aspects of the Guimarães Rosa´s story “A hora e vez de Augusto Matraga”, concerning to description sequences and its role in the configuration of the fictional space. We discuss a narrative matrix whose spatial and temporal structures reveal a trajectory towards the human being redemption – a kind of initiation journey, marked by the mystic of an ascetic life. The analyses also points to the recurrent themes of violence and religiousness that support the narrative tension, straightly related to the protagonist conflicts. Violence and religiousness express the initiation journey paradoxes. Our methodology adopts theoretical contributions of the Pragmatic Linguistics and the Textual Analysis of the Discourses.

Hard and soft acids and bases: atoms and atomic ions.

Science.gov (United States)

Reed, James L

2008-07-07

The structural origin of hard-soft behavior in atomic acids and bases has been explored using a simple orbital model. The Pearson principle of hard and soft acids and bases has been taken to be the defining statement about hard-soft behavior and as a definition of chemical hardness. There are a number of conditions that are imposed on any candidate structure and associated property by the Pearson principle, which have been exploited. The Pearson principle itself has been used to generate a thermodynamically based scale of relative hardness and softness for acids and bases (operational chemical hardness), and a modified Slater model has been used to discern the electronic origin of hard-soft behavior. Whereas chemical hardness is a chemical property of an acid or base and the operational chemical hardness is an experimental measure of it, the absolute hardness is a physical property of an atom or molecule. A critical examination of chemical hardness, which has been based on a more rigorous application of the Pearson principle and the availability of quantitative measures of chemical hardness, suggests that the origin of hard-soft behavior for both acids and bases resides in the relaxation of the electrons not undergoing transfer during the acid-base interaction. Furthermore, the results suggest that the absolute hardness should not be taken as synonymous with chemical hardness but that the relationship is somewhat more complex. Finally, this work provides additional groundwork for a better understanding of chemical hardness that will inform the understanding of hardness in molecules.

Hard Copy Market Overview

Testan, Peter R.

1987-04-01

A number of Color Hard Copy (CHC) market drivers are currently indicating strong growth in the use of CHC technologies for the business graphics marketplace. These market drivers relate to product, software, color monitors and color copiers. The use of color in business graphics allows more information to be relayed than is normally the case in a monochrome format. The communicative powers of full-color computer generated output in the business graphics application area will continue to induce end users to desire and require color in their future applications. A number of color hard copy technologies will be utilized in the presentation graphics arena. Thermal transfer, ink jet, photographic and electrophotographic technologies are all expected to be utilized in the business graphics presentation application area in the future. Since the end of 1984, the availability of color application software packages has grown significantly. Sales revenue generated by business graphics software is expected to grow at a compound annual growth rate of just over 40 percent to 1990. Increased availability of packages to allow the integration of text and graphics is expected. Currently, the latest versions of page description languages such as Postscript, Interpress and DDL all support color output. The use of color monitors will also drive the demand for color hard copy in the business graphics market place. The availability of higher resolution screens is allowing color monitors to be easily used for both text and graphics applications in the office environment. During 1987, the sales of color monitors are expected to surpass the sales of monochrome monitors. Another major color hard copy market driver will be the color copier. In order to take advantage of the communications power of computer generated color output, multiple copies are required for distribution. Product introductions of a new generation of color copiers is now underway with additional introductions expected

Full Text Available Abstract Background Despite the availability of conventional devices for making single-cell manipulations, determining the hardness of a single cell remains difficult. Here, we consider the cell to be a linear elastic body and apply Young’s modulus (modulus of elasticity, which is defined as the ratio of the repulsive force (stress in response to the applied strain. In this new method, a scanning probe microscope (SPM is operated with a cantilever in the “contact-and-push” mode, and the cantilever is applied to the cell surface over a set distance (applied strain. Results We determined the hardness of the following bacterial cells: Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and five Bacillus spp. In log phase, these strains had a similar Young’s modulus, but Bacillus spp. spores were significantly harder than the corresponding vegetative cells. There was a positive, linear correlation between the hardness of bacterial spores and heat or ultraviolet (UV resistance. Conclusions Using this technique, the hardness of a single vegetative bacterial cell or spore could be determined based on Young’s modulus. As an application of this technique, we demonstrated that the hardness of individual bacterial spores was directly proportional to heat and UV resistance, which are the conventional measures of physical durability. This technique allows the rapid and direct determination of spore durability and provides a valuable and innovative method for the evaluation of physical properties in the field of microbiology.

A Short Journey from Quarks to the Universe

CERN Document Server

Economou, Eleftherios N

2011-01-01

This book takes the reader for a short journey over the structures of matter showing that their main properties can be obtained even at a quantitative level with a minimum background knowledge. The latter, besides some high school physics and mathematics, consists of the three cornerstones of science presented in chapters 1 to 3, namely the atomic idea, the wave-particle duality, and the minimization of energy as the condition for equilibrium. Dimensional analysis employing the universal constants and combined with “a little imagination and thinking”, to quote Feynman, allows an amazing short-cut derivation of several quantitative results concerning the structures of matter. This book is expected to be of interest to physics, engineering, and other science students and to researchers in physics, material science, chemistry, and engineering who may find stimulating the alternative derivation of several real world results, which sometimes seem to pop out the magician’s hat.

Hard coatings

Dan, J.P.; Boving, H.J.; Hintermann, H.E.

1993-01-01

Hard, wear resistant and low friction coatings are presently produced on a world-wide basis, by different processes such as electrochemical or electroless methods, spray technologies, thermochemical, CVD and PVD. Some of the most advanced processes, especially those dedicated to thin film depositions, basically belong to CVD or PVD technologies, and will be looked at in more detail. The hard coatings mainly consist of oxides, nitrides, carbides, borides or carbon. Over the years, many processes have been developed which are variations and/or combinations of the basic CVD and PVD methods. The main difference between these two families of deposition techniques is that the CVD is an elevated temperature process (≥ 700 C), while the PVD on the contrary, is rather a low temperature process (≤ 500 C); this of course influences the choice of substrates and properties of the coating/substrate systems. Fundamental aspects of the vapor phase deposition techniques and some of their influences on coating properties will be discussed, as well as the very important interactions between deposit and substrate: diffusions, internal stress, etc. Advantages and limitations of CVD and PVD respectively will briefly be reviewed and examples of applications of the layers will be given. Parallel to the development and permanent updating of surface modification technologies, an effort was made to create novel characterisation methods. A close look will be given to the coating adherence control by means of the scratch test, at the coating hardness measurement by means of nanoindentation, at the coating wear resistance by means of a pin-on-disc tribometer, and at the surface quality evaluation by Atomic Force Microscopy (AFM). Finally, main important trends will be highlighted. (orig.)

Yang, Chun-Tien; Narayanasamy, Aru; Chang, Sung-Ling

2012-02-01

The aim of this study was to explore how hospitalization and the diagnosis of schizophrenia have an impact on Taiwanese patients' spiritual life. Psychiatric nurses tend to construe patients' spiritual issues as pathological problems and consequently are reluctant to address patient's spirituality, which results in spirituality being overlooked in mental illness. An individual's spiritual journey is dependent upon their cultural background and beliefs; however, the professional's preconceived ideas suppress the voice of patients with schizophrenia to share their experiences of their spiritual journey. The lack of research exploring spirituality in mental illness in Taiwan means that spiritual care is overlooked in practice. This study sets out to explore spirituality from the perspectives of patients in two mental hospitals in Taiwan. Using a qualitative approach, 22 long-term hospitalized patients diagnosed with schizophrenia were interviewed. Several themes from the data were identified using Ritchie and Spencer's (1994) five stages analytical framework. The study was carried out from 2006 to 2008. Patients revealed spiritual distress as a consequence of prolonged hospitalization. They used referents consistent with traditional Chinese philosophical perspectives derived from Taoism and Confucianism to describe various features of their spiritual distress and their longing for spiritual revival, transcendence and to be accepted as normal persons. In this age of globalization, nurses need to be fully cognisant of the cultural aspects of patients to respond to a mental health patient's spirituality. Clinical and educational guidelines and policies could be developed for spiritual care in Taiwan. © 2011 The Authors. Journal of Advanced Nursing © 2011 Blackwell Publishing Ltd.

Hard and soft acids and bases: structure and process.

Science.gov (United States)

Reed, James L

2012-07-05

Under investigation is the structure and process that gives rise to hard-soft behavior in simple anionic atomic bases. That for simple atomic bases the chemical hardness is expected to be the only extrinsic component of acid-base strength, has been substantiated in the current study. A thermochemically based operational scale of chemical hardness was used to identify the structure within anionic atomic bases that is responsible for chemical hardness. The base's responding electrons have been identified as the structure, and the relaxation that occurs during charge transfer has been identified as the process giving rise to hard-soft behavior. This is in contrast the commonly accepted explanations that attribute hard-soft behavior to varying degrees of electrostatic and covalent contributions to the acid-base interaction. The ability of the atomic ion's responding electrons to cause hard-soft behavior has been assessed by examining the correlation of the estimated relaxation energies of the responding electrons with the operational chemical hardness. It has been demonstrated that the responding electrons are able to give rise to hard-soft behavior in simple anionic bases.

Assessing particle mechanical properties of pharmaceutical materials quickly and with little material can be very important to early stages of pharmaceutical research. In this study, a wide range of pharmaceutical materials were studied using atomic force microscopy (AFM) nanoindentation. A significant amount of particle hardness and elastic modulus data were provided. Moreover, powder compact mechanical properties of these materials were investigated in order to build correlation between the particle hardness and powder compaction performance. It was found that the materials with very low or high particle hardness most likely exhibit poor compaction performance while the materials with medium particle hardness usually have good compaction behavior. Additionally, the results from this study enriched Hiestand's special case concept on particle hardness and powder compaction performance. This study suggests that the use of AFM nanoindentation can help to screen mechanical properties of pharmaceutical materials at early development stages of pharmaceutical research.

1995-01-01

Worldwide, hard coal mining is being carried out at ever increasing depth, and has, therefore, to cope with correspondingly increasing methane emissions are caused by coal mining. Beside carbon dioxide, chloro-fluoro-carbons (CFCs) and nitrogen oxides, methane is one of the most significant 'greenhouse' gases. It is mainly through the release of such trace gases that the greenhouse effect is brought about. Reducing methane emissions is therefore an important problem to be solved by the coal mining industry. This paper begins by highlighting some of the fundamental principles of methane in hard coal mining. The methane problem in German hard coal mining and the industry's efforts to reduce methane emissions are presented. The future development in German hard coal mining is illustrated by an example which shows how large methane volumes can be managed, while still maintaining high outputs at increasing depth.

Double parton scattering in proton-proton collisions includes kinematic regions in which two partons inside a proton originate from the perturbative splitting of a single parton. This leads to a double counting problem between single and double hard scattering. We present a solution to this problem, which allows for the definition of double parton distributions as operator matrix elements in a proton, and which can be used at higher orders in perturbation theory. We show how the evaluation of double hard scattering in this framework can provide a rough estimate for the size of the higher-order contributions to single hard scattering that are affected by double counting. In a numeric study, we identify situations in which these higher-order contributions must be explicitly calculated and included if one wants to attain an accuracy at which double hard scattering becomes relevant, and other situations where such contributions may be neglected.

Full Text Available Background/Aim. Speech motor mechanisms play a crucial role in the process of demutization, due to the fact that they cover all the elements of the successive development of spech production movements leading to speech formation (socalled kinesthesia in speach. The aim of this study was to estimate the impact of perceptual motor actions on the cognitive process of reading in 130 students in regular schools and schools for the deaf and hard-of-hearing children in the Republic of Serbia. Methods. Kostić and Vladisavljević test consisted of the ten levels weight was used for the assessment of reading speed. To assess understanding of text read by verbal responses, we used three-dimensional adapted reading test of Helene Sax. Results. The triage-articulation test for assessing reading speed (Kostić and Vladisavljević’s test according to the weight of ten levels, revealed that students in regular schools statistically significantly faster read texts as compared to the deaf students. The results of the threedimensional adapted reading test of Helena Sax, show that the words learned by deaf children exist in isolation in their mind, ie, if there is no standard of acoustic performance for graphic image, in deaf child every word, printed or written, is just the sum of letters without meaning. Conclusion. There is a significant difference in text reading speed and its understanding among the children who hear and the deaf and hard of-hearing children. It is essential that in deaf and heard-of hearing children education, apart from the development of speech, parallelly use the concept of semantic processing in order to get each word by the fullness of its content and the possibility of expanding its meaning in a variety of assets.

Speech motor mechanisms play a crucial role in the process of demutization, due to the fact that they cover all the elements of the successive development of spech production movements leading to speech formation (so-called kinesthesia in speach). The aim of this study was to estimate the impact of perceptual motor actions on the cognitive process of reading in 130 students in regular schools and schools for the deaf and hard-of-hearing children in the Republic of Serbia. Kostić and Vladisavljević test consisted of the ten levels weight was used for the assessment of reading speed. To assess understanding of text read by verbal responses, we used three-dimensional adapted reading test of Helene Sax. The triage-articulation test for assessing reading speed (Kostié and Vladisavljević's test according to the weight of ten levels, revealed that students in regular schools statistically significantly faster read texts as compared to the deaf students. The results of the three-dimensional adapted reading test of Helena Sax, show that the words learned by deaf children exist in isolation in their mind, i.e., if there is no standard of acoustic performance for graphic image, in deaf child every word, printed or written, is just the sum of letters without meaning. There is a significant difference in text reading speed and its understanding among the children who hear and the deaf and hard-of-hearing children. It is essential that in deaf and heard-of-hearing children education, apart from the development of speech, parallelly use the concept of semantic processing in order to get each word by the fullness of its content and the possibility of expanding its meaning in a variety of assets.

Directory of Open Access Journals (Sweden)

JH Nel

2008-12-01

Full Text Available National census data contain information on place of residence and place of work. It is possible to combine this information~and create journey-to-work flows. The process of establishing these flows are presented in this paper. The intramax method is explained and used to identify functional regions based upon these flows. Interesting applications, such as the demarcation of regions in South Africa are considered and solutions to disputed areas are put forward. The process of the creation of the current provincial boundaries are discussed. New boundaries, based on the intramax analysis of the journey-to-work data are proposed for four or five new provinces. Results compare favourably with those from a principal component and cluster analysis, which has previously been used to demarcate the South African space economy into a hierarchy of development regions.

MSFC is interested in developing hard thin film coating for bearings. The wearing of the bearing is an important problem for space flight engine. Hard thin film coating can drastically improve the surface of the bearing and improve the wear-endurance of the bearing. However, many fundamental problems in surface physics, plasma deposition, etc, need further research. The approach is using electron cyclotron resonance chemical vapor deposition (ECRCVD) to deposit hard thin film an stainless steel bearing. The thin films in consideration include SiC, SiN and other materials. An ECRCVD deposition system is being assembled at MSFC.

Subgroup report on hard x-ray microprobes

Ice, G.E.; Barbee, T.; Bionta, R.; Howells, M.; Thompson, A.C.; Yun, W.

1994-01-01

The increasing availability of synchrotron x-ray sources has stimulated the development of advanced hard x-ray (E≥5 keV) microprobes. New x-ray optics have been demonstrated which show promise for achieving intense submicron hard x-ray probes. These probes will be used for extraordinary elemental detection by x-ray fluorescence/absorption and for microdiffraction to identify phase and strain. The inherent elemental and crystallographic sensitivity of an x-ray microprobe and its inherently nondestructive and penetrating nature makes the development of an advanced hard x-ray microprobe an important national goal. In this workshop state-of-the-art hard x-ray microprobe optics were described and future directions were discussed. Gene Ice, Oak Ridge National Laboratory (ORNL), presented an overview of the current status of hard x-ray microprobe optics and described the use of crystal spectrometers to improve minimum detectable limits in fluorescent microprobe experiments. Al Thompson, Lawrence Berkeley Laboratory (LBL), described work at the Center for X-ray Optics to develop a hard x-ray microprobe based on Kirkpatrick-Baez (KB) optics. Al Thompson also showed the results of some experimental measurements with their KB optics. Malcolm Howells presented a method for bending elliptical mirrors and Troy Barbee commented on the use of graded d spacings to achieve highest efficiency in KB multilayer microfocusing. Richard Bionta, Lawrence Livermore National Laboratory (LLNL), described the development of the first hard x-ray zone plates and future promise of so called open-quotes jelly rollclose quotes or sputter slice zone plates. Wenbing Yun, Argonne National Laboratory (ANL), described characterization of jelly roll and lithographically produced zone plates and described the application of zone plates to focus extremely narrow bandwidths by nuclear resonance. This report summarizes the presentations of the workshop subgroup on hard x-ray microprobes

Wilson, Candice T; Fletcher, Paula C

Although death is inevitable, it continues to remain a taboo issue for society. A failure to discuss the unavoidable may represent a safeguard to avoid dealing with mortality and related fears. Many patients who are terminally ill spend their days feeling alone, misunderstood, and afraid. Kubler-Ross attempted to strip death of its negative connotations and to provide a venue for the terminally ill to have a voice. Using information from more than 200 clinical interviews, Kubler-Ross revealed a trend in emotions over time in most, but not all, of her patients, which enabled her to formulate a model of coping with death that included 5 interdependent emotional stages: denial, anger, bargaining, depression, and acceptance. This model has become the most widely accepted and popularized model on death and dying, often cited as the Five Stages of Grief." However, given the lack of research concerning Kubler-Ross's model, completing work in this area seems warranted. The purpose of this case study was to examine one individual's emotional journey after being diagnosed with terminal colon cancer. More specifically, the goals were twofold: (1) to provide the participant with a voice and to allow her story to be told by examining the major external events (ie,surgery, chemotherapy) occurring since the diagnosis that affected her emotional and physical well-being and (2) to determine whether the participant's emotional journey paralleled Kubler-Ross's model, to what extent, and whether new emotions or stages occurred. The participant, a 50-year-old female, was diagnosed with stage 4 Duke Stage D colon cancer. Qualitative information was collected in face-to-face interviews, newspaper articles about the participant, and e-mail correspondence (as form letters to a group of friends and supporters) and subsequently analyzed for trends. The overall results revealed clear existence of the 5 stages of grief as outlined in the Kubler-Ross model. Analyses also revealed that the

Block co-polymers PCTBVs (M(n) of 36,300-65,300 g/mol, T(m) of 39-40 and 142 degrees C) containing hyperbranched three-arm poly(epsilon-caprolactone) (PCL) as switching segment and microbial polyester PHBV as crystallizable hard segment were designed as biodegradable shape-memory polymer (SMP) for fast self-expandable stent and synthesized in 96% yield by the reaction of three-arm PCL-triol (M(n) of 4200 g/mol, T(m) of 47 degrees C) with methylene diphenyl 4,4'-diisocyanate isocynate (MDI) to form the hyperbrached MDI-linked PCL (PTCM; M(n) of 25,400 g/mol and a T(m) of 38 degrees C), followed by further polymerization with PHBV-diol (M(n) of 2200 g/mol, T(m) of 137 and 148 degrees C). The polymers were characterized by (1)H NMR, GPC, DSC, tensile test, and cyclic thermomechanical tensile test. PCTBVs showed desired thermal properties, mechanical properties, and ductile nature. PCTBV containing 25 wt% PHBV (PCTBV-25) demonstrated excellent shape-memory property at 40 degrees C, with R(f) of 94%, R(r) of 98%, and shape recovery within 25s. PCTBV-25 was also shown as a safe material with good biocompatibility by cytotoxicity tests and cell growth experiments. The stent made from PCTBV-25 film showed nearly complete self-expansion at 37 degrees C within only 25 s, which is much better and faster than the best known self-expandable stents.

Total hip arthroplasty has shown excellent results in decreasing pain and improving function in patients with degenerative disease of the hip. Improvements in prosthetic materials, designs and implant fixation have now resulted in wear of the bearing surface being the limitation of this technology, and a number of hard-on-hard couples have been introduced to address this concern. The purpose of this article is to review the origins, development, survival rates and potential advantages and disadvantages of the following hard-on-hard bearings for total hip arthroplasty: metal-on-metal standard total hip arthroplasty; metal-on-metal hip resurfacing arthroplasty, ceramic-on-ceramic total hip arthroplasty; and ceramic-on-metal bearings. Improvements in the manufacturing of metal-on-metal bearings over the past 50 years have resulted in implants that provide low wear rates and allow for the use of large femoral heads. However, concerns remain regarding elevated serum metal ion levels, potential teratogenic effects and potentially devastating adverse local tissue reactions, whose incidence and pathogenesis remains unclear. Modern total hip resurfacing has shown excellent outcomes over 10 years in the hands of experienced surgeons. Current ceramic-on-ceramic bearings have demonstrated excellent survival with exceptionally low wear rates and virtually no local adverse effects. Concerns remain for insertional chipping, in vivo fracture and the variable incidence of squeaking. Contemporary ceramic-on-metal interfaces are in the early stages of clinical use, with little data reported to date. Hard-on-hard bearings for total hip arthroplasty have improved dramatically over the past 50 years. As bearing designs continue to improve with new and modified materials and improved manufacturing techniques, it is likely that the use of hard-on-hard bearings will continue to increase, especially in young and active patients.

Journeys to Others and Lessons of Self: Carlos Castaneda in Camposcape

Directory of Open Access Journals (Sweden)

Ageeth Sluis

2012-12-01

Full Text Available Drawing on Michel Foucault’s concept of heterotopia, this article examines the importance of place and gender within constructions of race politics in Carlos Castaneda’s series on shamanism. Championing a “separate reality” predicated on an indigenous worldview, Castaneda’s lessons invited transnational middle-class youth to "journey" alongside him to camposcape—an anachronistic and idealized countryside—as a means to escape the bourgeois values of their homelands and find spiritual fulfillment in a timeless and "authentic" Mexico. Castaneda’s work proposed new viable spaces of difference in Mexico, yet inscribed these spaces with a masculinist discourse that served to neutralize the gender trouble within the counterculture movement in both Mexico and the US.

From the best-selling author of Seven Brief Lessons on Physics comes a new book about the mind-bending nature of the universe. What are time and space made of? Where does matter come from? And what exactly is reality? Scientist Carlo Rovelli has spent his whole life exploring these questions and pushing the boundaries of what we know. Here he explains how our image of the world has changed throughout centuries. From Aristotle to Albert Einstein, Michael Faraday to the Higgs boson, he takes us on a wondrous journey to show us that beyond our ever-changing idea of reality is a whole new world that has yet to be discovered.

Hard processes in hadronic interactions

International Nuclear Information System (INIS)

Satz, H.; Wang, X.N.

1995-01-01

Quantum chromodynamics is today accepted as the fundamental theory of strong interactions, even though most hadronic collisions lead to final states for which quantitative QCD predictions are still lacking. It therefore seems worthwhile to take stock of where we stand today and to what extent the presently available data on hard processes in hadronic collisions can be accounted for in terms of QCD. This is one reason for this work. The second reason - and in fact its original trigger - is the search for the quark-gluon plasma in high energy nuclear collisions. The hard processes to be considered here are the production of prompt photons, Drell-Yan dileptons, open charm, quarkonium states, and hard jets. For each of these, we discuss the present theoretical understanding, compare the resulting predictions to available data, and then show what behaviour it leads to at RHIC and LHC energies. All of these processes have the structure mentioned above: they contain a hard partonic interaction, calculable perturbatively, but also the non-perturbative parton distribution within a hadron. These parton distributions, however, can be studied theoretically in terms of counting rule arguments, and they can be checked independently by measurements of the parton structure functions in deep inelastic lepton-hadron scattering. The present volume is the work of Hard Probe Collaboration, a group of theorists who are interested in the problem and were willing to dedicate a considerable amount of their time and work on it. The necessary preparation, planning and coordination of the project were carried out in two workshops of two weeks' duration each, in February 1994 at CERn in Geneva andin July 1994 at LBL in Berkeley

Seismic signals hard clipping overcoming

Science.gov (United States)

Olszowa, Paula; Sokolowski, Jakub

2018-01-01

In signal processing the clipping is understand as the phenomenon of limiting the signal beyond certain threshold. It is often related to overloading of a sensor. Two particular types of clipping are being recognized: soft and hard. Beyond the limiting value soft clipping reduces the signal real gain while the hard clipping stiffly sets the signal values at the limit. In both cases certain amount of signal information is lost. Obviously if one possess the model which describes the considered signal and the threshold value (which might be slightly more difficult to obtain in the soft clipping case), the attempt of restoring the signal can be made. Commonly it is assumed that the seismic signals take form of an impulse response of some specific system. This may lead to belief that the sine wave may be the most appropriate to fit in the clipping period. However, this should be tested. In this paper the possibility of overcoming the hard clipping in seismic signals originating from a geoseismic station belonging to an underground mine is considered. A set of raw signals will be hard-clipped manually and then couple different functions will be fitted and compared in terms of least squares. The results will be then analysed.

Rotation of hard particles in a soft matrix

Science.gov (United States)

Yang, Weizhu; Liu, Qingchang; Yue, Zhufeng; Li, Xiaodong; Xu, Baoxing

Soft-hard materials integration is ubiquitous in biological materials and structures in nature and has also attracted growing attention in the bio-inspired design of advanced functional materials, structures and devices. Due to the distinct difference in their mechanical properties, the rotation of hard phases in soft matrixes upon deformation has been acknowledged, yet is lack of theory in mechanics. In this work, we propose a theoretical mechanics framework that can describe the rotation of hard particles in a soft matrix. The rotation of multiple arbitrarily shaped, located and oriented particles with perfectly bonded interfaces in an elastic soft matrix subjected to a far-field tensile loading is established and analytical solutions are derived by using complex potentials and conformal mapping methods. Strong couplings and competitions of the rotation of hard particles among each other are discussed by investigating numbers, relative locations and orientations of particles in the matrix at different loading directions. Extensive finite element analyses are performed to validate theoretical solutions and good agreement of both rotation and stress field between them are achieved. Possible extensions of the present theory to non-rigid particles, viscoelastic matrix and imperfect bonding are also discussed. Finally, by taking advantage of the rotation of hard particles, we exemplify an application in a conceptual design of soft-hard material integrated phononic crystal and demonstrate that phononic band gaps can be successfully tuned with a high accuracy through the mechanical tension-induced rotation of hard particles. The present theory established herein is expected to be of immediate interests to the design of soft-hard materials integration based functional materials, structures and devices with tunable performance via mechanical rotation of hard phases.

The botanical legacy of Thomas Hardwicke’s journey to Srinagar in 1796

Directory of Open Access Journals (Sweden)

Ian M. Turner

2015-01-01

Full Text Available In 1796, Thomas Hardwicke travelled through northern India between what is now Fatehgarh in Uttar Pradesh and Srinagar in Uttarakhand. Hardwicke collected and described plants encountered and had many of the plants illustrated from life. He published an account of the journey in 1799 including a list of plant species. I review the names validated in the original paper, and also those published subsequently by Sir James Edward Smith and William Roxburgh based partly or wholly on the material or drawings acquired by Hardwicke on the journey to Srinagar. The large collection of Hardwicke plant drawings now held in the British Library, and a smaller set in the Botany Library of the Natural History Museum, are considered in relation to the application and typification of plant names related to Hardwicke’s botanical exploration in India. The names of seven plant species were validly published in the 1799 paper (Androsace rotundifolia Hardw., Ficus laminosa Hardw., Justicia thyrsiformis Roxb. ex Hardw., Linum trigynum Roxb. ex Hardw., Lonicera quinquelocularis Hardw., Salvia integrifolia Roxb. ex Hardw. and Volkameria bicolor Hardw., plus one new combination (Echites antidysentericus (L. Roxb. ex Hardw.. As concluded by Britten more than a century ago, Ficus laminosa is the correct name for the fig variously referred to F. saemocarpa Miq. or F. squamosa Roxb. Smith based Rhododendron arboreum Sm. and Bignonia undulata Sm. on Hardwicke plants. At least a dozen Roxburgh names, including Crataegus integrifolia Roxb., Gardenia tetrasperma Roxb. and Morus serrata Roxb., are based, at least partly, on Hardwicke’s collections. In total, 23 names are lectotypified here and one neotype is designated.

A journey toward wholeness, a journey to God: physical fitness as embodied spirituality.

Science.gov (United States)

Greenwood, Tracey C; Delgado, Teresa

2013-09-01

Physical fitness expressed through exercise can be, if done with the right intention, a form of spiritual discipline that reflects the relational love of humanity to God as well as an expression of a healthy love of the embodied self. Through an analysis of the physiological benefits of exercise science applied to the human body, this paper will demonstrate how such attention to the optimal physical fitness of the body, including weight and cardiovascular training and nutrition, is an affirmation of three foundational theological principles of human embodiment: as created in the "imago Dei", as unified body/spirit, and as part of God's creation calling for proper stewardship. In a contemporary climate where women's bodies in particular are viewed through the lens of commodification-as visual objects for sale based on prescribed notions of superficial esthetics and beauty-as well as the consistently high rates of eating disorders such as anorexia, bulimia, and obesity, authors Greenwood and Delgado offer a vision of how women and men can imagine a subjective relationship with their own bodies that reflects the abundant love of God for God's creation. Spoken from the lived experience of professional fitness competitor and trainer, as well as trained biokineticist, Dr. Greenwood presents the most current scientific data in the field of biokinetics that grounds the theological analysis offered by Dr. Delgado, whose personal journey through anorexia and scholarly emphasis on Christian theological anthropology inform this work. Taken together, Greenwood and Delgado suggest a response to God's love for humanity, including our physical bodily humanity, which entails a responsibility to attend to the physical fitness of our bodies in order to live into the fullness, flourishing and love of God's creation as God intended.

A Rapidly Expanding Bose-Einstein Condensate: An Expanding Universe in the Lab

Science.gov (United States)

Eckel, S.; Kumar, A.; Jacobson, T.; Spielman, I. B.; Campbell, G. K.

2018-04-01

We study the dynamics of a supersonically expanding, ring-shaped Bose-Einstein condensate both experimentally and theoretically. The expansion redshifts long-wavelength excitations, as in an expanding universe. After expansion, energy in the radial mode leads to the production of bulk topological excitations—solitons and vortices—driving the production of a large number of azimuthal phonons and, at late times, causing stochastic persistent currents. These complex nonlinear dynamics, fueled by the energy stored coherently in one mode, are reminiscent of a type of "preheating" that may have taken place at the end of inflation.

Hard exclusive QCD processes

Kugler, W.

2007-01-15

Hard exclusive processes in high energy electron proton scattering offer the opportunity to get access to a new generation of parton distributions, the so-called generalized parton distributions (GPDs). This functions provide more detailed informations about the structure of the nucleon than the usual PDFs obtained from DIS. In this work we present a detailed analysis of exclusive processes, especially of hard exclusive meson production. We investigated the influence of exclusive produced mesons on the semi-inclusive production of mesons at fixed target experiments like HERMES. Further we give a detailed analysis of higher order corrections (NLO) for the exclusive production of mesons in a very broad range of kinematics. (orig.)

1995-09-01

The role of s-channel unitarity screening corrections, calculated in the eikonal approximation, is investigated for soft Pomeron exchange responsible for elastic and diffractive hadron scattering in the high energy limit. We examine the differences between our results and those obtained from the supercritical Pomeron-Regge model with no such corrections. It is shown that screening saturation is attained at different scales for different channels. We then proceed to discuss the new HERA data on hard (PQCD) Pomeron diffractive channels and discuss the relationship between the soft and hard Pomerons and the relevance of our analysis to this problem.

Journey of a molecular biologist.

Science.gov (United States)

Nomura, Masayasu

2011-01-01

My journey into a research career began in fermentation biochemistry in an applied science department during the difficult post-World War II time in Japan. Subsequently, my desire to do research in basic science developed. I was fortunate to be a postdoctoral fellow in the United States during the early days of molecular biology. From 1957 to 1960, I worked with three pioneers of molecular biology, Sol Spiegelman, James Watson, and Seymour Benzer. These experiences helped me develop into a basic research scientist. My initial research projects at Osaka University, and subsequently at the University of Wisconsin, Madison, were on the mode of action of colicins as well as on mRNA and ribosomes. Following success in the reconstitution of ribosomal subunits, my efforts focused more on ribosomes, initially on the aspects of structure, function, and in vitro assembly, such as the construction of the 30S subunit assembly map. After this, my laboratory studied the regulation of the synthesis of ribosomes and ribosomal components in Escherichia coli. Our achievements included the discovery of translational feedback regulation of ribosomal protein synthesis and the identification of several repressor ribosomal proteins used in this regulation. In 1984, I moved to the University of California, Irvine, and initiated research on rRNA transcription by RNA polymerase I in the yeast Saccharomyces cerevisiae. The use of yeast genetics combined with biochemistry allowed us to identify genes uniquely involved in rRNA synthesis and to elucidate the mechanism of initiation of transcription. This essay is a reflection on my life as a research scientist.

Optimising hard X-ray generation from laser-produced plasmas

International Nuclear Information System (INIS)

Lindheimer, C.

1995-04-01

The aim of this work is to increase the X-ray yield for a laser produced plasma by optimising the focusing conditions and temporal shape of the laser pulses. The focusing conditions are improved by introducing a control system that secures the laser target surface to exact focus within a range of a few micrometers, allowing continuously high laser intensity for plasma generation. The temporal shape of the laser pulses is changed by introducing a saturable absorber in the laser beam. The laser produces a substantial pre-pulse that heats and expands the target material prior to main pulse arrival. The saturable absorber can increase the main pulse/pre-pulse ratio of the laser pulse up to four orders of magnitude and consequently reduce expansion of the target material before the main pulse. The belief is that an increase in target density at the time of main pulse arrival will change the energy distribution of the X-rays, towards a more efficient X-ray production in the hard X-ray region. This report and the work connected to it, includes the preliminary measurements and results for these improvements. 17 refs

Clark, Kevin W; Moller, Susan; O'Brien, Lauri

2014-06-01

Internationally, there is growing interest in the applicability of visual management in healthcare, although little is known about the extent of its effectiveness. In the past 5 years technical advances have permitted the integration of all relevant data into a singular display that can improve staff efficiency, accelerate decisions, streamline workflow processes and reduce oversights and errors in clinical practice. The aim of the case study is to describe the features and application of electronic patient journey boards (EPJBs) as an enabler to accelerate patient flow that has been demonstrated and evaluated in Queensland Health hospitals. In 2012 and 2013 we collected ward-specific data that was sourced from the Queensland Hospital Admitted Patient Data Collection, determining the top 10 overnight diagnostic-related groups (DRGs) for each ward participating in the pilots. The Statistical Output Unit within Queensland Health then provided data and analysis on the ALOS for each of these DRGs for the period following an EPJB installation, along with the ALOS for the same DRGs for the corresponding period in the previous year. Patient length of stay reduced and display of estimated discharge dates improved with the introduction of EPJBs along with improved communication and information management resulting in time savings from 20 min per staff member per shift to 2.5h per ward a day. Queensland and South Australian Health systems have succeeded in 'making the hospital patient journey visible' through an innovative combination of information management and prominent display of key information related to patient care portrayed on large liquid crystal display (LCD) screens in hospital wards.

Discovery Mondays - Neutrinos: journeying with the phantom particles

CERN Multimedia

2006-01-01

The target of the CNGS facility at CERN, which will enable the production of neutrinos. On 29 May, CNGS (CERN Neutrinos to Gran Sasso) will send the first neutrino beams from CERN to the Gran Sasso Laboratory in Italy. The neutrinos will journey 730 km through the earth's crust. To mark the occasion, Discovery Mondays is organising a special evening devoted to the CNGS project, whose purpose is to provide us with a better understanding of the neutrino, a particle that is still shrouded in mystery. The neutrino is an elusive particle that is very difficult to study. Masters of the art of evading capture, neutrinos can pass through thousands of kilometres of matter with little or no interaction. As you are reading this text, 400000 billion neutrinos from the sun are passing through your body every second. However, only one or two will be stopped by your body during your entire lifetime. Detecting neutrinos is therefore a very arduous task. This is why we still know so little about them. At the next Discovery ...

The current global refugee crisis involves 65.3 million persons who have been displaced from their homes or countries of origin. While escaping immediate harm may be their first priority, displaced people go on to face numerous health risks, including trauma and injuries, malnutrition, infectious diseases, exacerbation of existing chronic diseases, and mental health conditions. This crisis highlights the importance of building capacity among health-care providers, scientists, and laboratorians to understand and respond to the health needs of refugees. The November 2016 American Society of Tropical Medicine and Hygiene (ASTMH) conference in Atlanta will feature an interactive exhibit entitled "The Refugee Journey to Wellbeing" and three symposia about refugee health. The symposia will focus on tropical disease challenges in refugee populations, careers in refugee health, and recent experiences of governmental agencies and nongovernmental organizations in responding to the global refugee crisis. We invite ASTMH attendees to attend the exhibit and symposia and consider contributions they could make to improve refugee health through tropical disease research or clinical endeavors. © The American Society of Tropical Medicine and Hygiene.

Berger, E.L.; Collins, J.C.; Soper, D.E.; Sterman, G.

1986-02-01

Conclusions concerning the properties of hard scattering in diffractively produced systems are summarized. One motivation for studying diffractive hard scattering is to investigate the interface between Regge theory and perturbative QCD. Another is to see whether diffractive triggering can result in an improvement in the signal-to-background ratio of measurements of production of very heavy quarks. 5 refs

Complex technique for materials hardness measurement

1984-01-01

A review of existing methods of measurement of material hardness in national and foreign practice has been made. A necessity of improving the technique of material hardness measurement in a wide temperature range and insuring load change with indenting, continuity of imprint application, smooth changing of temperatures along a sample length, and deformation rate control has been noted.

Seismic loads in modularized and unmodularized large pools located on hard or intermediate hard sites

Energy Technology Data Exchange (ETDEWEB)

Dong, R G [California Univ., Livermore (USA). Lawrence Livermore Lab.

1977-12-01

To augment the present capacity of pools for storing spent nuclear fuel elements, pools larger than those in current use are being planned. These pools may or may not be modularized into cells. Because of the large size of the pools, seismic loads are of significant interest. In particular, the effects of modularization and site hardness are of concern. The study presented in this paper reveals that modularization is generally unfavourable, because it creates the option of leaving one or more cells empty which in turn results in higher structural loads. The wall which separates a filled cell from an empty cell, or the wall which bears against earth on one side and faces an empty cell on the other, becomes very highly stressed. For the particular pool geometries examined, a hard site is generally preferred over an intermediate hard site in terms of structural loads.

Micro-computer cards for hard industrial environment

Approximately 60% of present or future distributed systems have, or will have, operational units installed in hard environments. In these applications, which include canalization and industrial motor control, robotics and process control, systems must be easily applied in environments not made for electronic use. The development of card systems in this hard industrial environment, which is found in petrochemical industry and mines is described. National semiconductor CIM card system CMOS technology allows the real time micro computer application to be efficient and functional in hard industrial environments.

Transport coefficients and mechanical response in hard-disk colloidal suspensions

2016-01-01

We investigate the transport properties and mechanical response of glassy hard disks using nonlinear Langevin equation theory. We derive expressions for the elastic shear modulus and viscosity in two dimensions on the basis of thermal-activated barrier-hopping dynamics and mechanically accelerated motion. Dense hard disks exhibit phenomena such as softening elasticity, shear-thinning of viscosity, and yielding upon deformation, which are qualitatively similar to dense hard-sphere colloidal suspensions in three dimensions. These phenomena can be ascribed to stress-induced “landscape tilting”. Quantitative comparisons of these phenomena between hard disks and hard spheres are presented. Interestingly, we find that the density dependence of yield stress in hard disks is much more significant than in hard spheres. Our work provides a foundation for further generalizing the nonlinear Langevin equation theory to address slow dynamics and rheological behavior in binary or polydisperse mixtures of hard or soft disks.

CMOS optimization for radiation hardness

International Nuclear Information System (INIS)

Derbenwick, G.F.; Fossum, J.G.

1975-01-01

Several approaches to the attainment of radiation-hardened MOS circuits have been investigated in the last few years. These have included implanting the SiO 2 gate insulator with aluminum, using chrome-aluminum layered gate metallization, using Al 2 O 3 as the gate insulator, and optimizing the MOS fabrication process. Earlier process optimization studies were restricted primarily to p-channel devices operating with negative gate biases. Since knowledge of the hardness dependence upon processing and design parameters is essential in producing hardened integrated circuits, a comprehensive investigation of the effects of both process and design optimization on radiation-hardened CMOS integrated circuits was undertaken. The goals are to define and establish a radiation-hardened processing sequence for CMOS integrated circuits and to formulate quantitative relationships between process and design parameters and the radiation hardness. Using these equations, the basic CMOS design can then be optimized for radiation hardness and some understanding of the basic physics responsible for the radiation damage can be gained. Results are presented

In late 1994, the U.S. Department of Energy (Nevada Operations Office) made a $199,708 grant (through the Mathematics, Science, and Technology Education Program), to the UNFINISHED JOURNEY Project. The Project began in April, 1994, to develop and implement an innovative model of student outreach by San Jose State University (SJSU) to underserved, underrepresented student populations of the East Side Union High School District (ESUHSD). The Project was formed by a consortium involving SJSU, ESUHSD, some 20 private sector organizations (foundations/corporations), numerous local community/professional organizations, and approximately 100 private funders. This proposal to the U.S. Department of Energy was to have the Department join this unique partnership to focus University outreach to underserved student populations to pursue careers in mathematics, science, and technology.

Novel hard compositions and methods of preparation

Science.gov (United States)

Sheinberg, H.

1983-08-23

Novel very hard compositions of matter are prepared by using in all embodiments only a minor amount of a particular carbide (or materials which can form the carbide in situ when subjected to heat and pressure); and no strategic cobalt is needed. Under a particular range of conditions, densified compositions of matter of the invention are prepared having hardnesses on the Rockwell A test substantially equal to the hardness of pure tungsten carbide and to two of the hardest commercial cobalt-bonded tungsten carbides. Alternately, other compositions of the invention which have slightly lower hardnesses than those described above in one embodiment also possess the advantage of requiring no tungsten and in another embodiment possess the advantage of having a good fracture toughness value. Photomicrographs show that the shapes of the grains of the alloy mixture with which the minor amount of carbide (or carbide-formers) is mixed are radically altered from large, rounded to small, very angular by the addition of the carbide. Superiority of one of these hard compositions of matter over cobalt-bonded tungsten carbide for ultra-high pressure anvil applications was demonstrated. 3 figs.

Study of Cu-Al-Zn alloys hardness temperature dependence

Kurmanova, D.T.; Skakov, M.K.; Melikhov, V.D.

2001-01-01

In the paper the results of studies for the Cu-Al-Zn ternary alloys hardness temperature dependence are presented. The method of 'hot hardness' has been used during study of the solid state phase transformations and under determination of the hot stability boundaries. Due to the samples brittleness a hardness temperature dependence definition is possible only from 350-400 deg. C. Sensitivity of the 'hot hardness' method is decreasing within high plasticity range, so the measurements have been carried out only up to 700-800 deg. C. It is shown, that the alloys hardness dependence character from temperature is close to exponential one within the certain structure modification existence domain

Synthesis, Structure, and Properties of Refractory Hard-Metal Borides

Science.gov (United States)

Lech, Andrew Thomas

As the limits of what can be achieved with conventional hard compounds, such as tungsten carbide, are nearing reach, super-hard materials are an area of increasing industrial interest. The refractory hard metal borides, such as ReB2 and WB4, offer an increasingly attractive alternative to diamond and cubic boron nitride as a next-generation tool material. In this Thesis, a thorough discussion is made of the progress achieved by our laboratory towards understanding the synthesis, structure, and properties of these extremely hard compounds. Particular emphasis is placed on structural manipulation, solid solution formation, and the unique crystallographic manifestations of what might also be called "super-hard metals".

A Rapidly Expanding Bose-Einstein Condensate: An Expanding Universe in the Lab

Directory of Open Access Journals (Sweden)

S. Eckel

2018-04-01

Full Text Available We study the dynamics of a supersonically expanding, ring-shaped Bose-Einstein condensate both experimentally and theoretically. The expansion redshifts long-wavelength excitations, as in an expanding universe. After expansion, energy in the radial mode leads to the production of bulk topological excitations—solitons and vortices—driving the production of a large number of azimuthal phonons and, at late times, causing stochastic persistent currents. These complex nonlinear dynamics, fueled by the energy stored coherently in one mode, are reminiscent of a type of “preheating” that may have taken place at the end of inflation.

Hardness of basaltic glass-ceramics

2009-01-01

The dependence of the hardness of basaltic glass-ceramics on their degree of crystallisation has been explored by means of differential scanning calorimetry, optical microscopy, x-ray diffraction, and Vickers indentation. Different degrees of crystallisation in the basaltic glasses were achieved...... by varying the temperature of heat treatment. The predominant crystalline phase in the glass was identified as augite. It was found that the hardness of the glass phase decreased slightly with an increase in the degree of crystallisation, while that of the augite phase drastically decreased....

Hard template synthesis of metal nanowires

Kawamura, Go; Muto, Hiroyuki; Matsuda, Atsunori

2014-11-01

Metal nanowires (NWs) have attracted much attention because of their high electron conductivity, optical transmittance and tunable magnetic properties. Metal NWs have been synthesized using soft templates such as surface stabilizing molecules and polymers, and hard templates such as anodic aluminum oxide, mesoporous oxide, carbon nanotubes. NWs prepared from hard templates are composites of metals and the oxide/carbon matrix. Thus, selecting appropriate elements can simplify the production of composite devices. The resulting NWs are immobilized and spatially arranged, as dictated by the ordered porous structure of the template. This avoids the NWs from aggregating, which is common for NWs prepared with soft templates in solution. Herein, the hard template synthesis of metal NWs is reviewed, and the resulting structures, properties and potential applications are discussed.

Hard diffraction and small-x

International Nuclear Information System (INIS)

Anon.

1995-01-01

In the United States, phrases such as ''small-x evolution'', ''the BFKL Pomeron'', ''deep-inelastic rapiditygap events'' and ''hard-diffraction'' do not generate the same intensity of discussion amongst high-energy physicists that they do in Europe. However, for three days in the fall such discussion filled the air at Fermilab. The ''2nd Workshop on Small-x and Diffractive Physics at the Tevatron'' was a review of the rapid theoretical and experimental progress taking place in this field. Although Quantum Chromo-dynamics (QCD) has been established as the theory of strong interactions for twenty years, as yet neither perturbative high-energy calculations nor low-energy non-perturbative techniques have been successfully extended to the mixture of high energy and low transverse momenta which characterize traditional ''soft'' diffractive processes. The simplest soft diffractive process is elastic scattering. In this case it is easiest to accept that there is an exchanged ''pomeron'', which can be pictured as a virtual entity with no electric charge or strong charge (colour), perhaps like an excitation of the vacuum. The same pomeron is expected to appear in all diffractive processes. Understanding the pomeron in QCD is a fundamental theoretical and experimental challenge. In the last two or three years the ''frontier'' in this challenging area of QCD has been pushed back significantly in both theory and experiment. Progress has been achieved by studying the evolution of hard collisions to relatively smaller constituent momenta (small x) and by studying ''hard'' diffractive collisions containing simultaneous signatures of diffraction and hard perturbative processes. The hard processes have included high transverse momentum jet production, deep inelastic lepton scattering, and (most recently) W

"Work smart, wear your hard hat"

CERN Multimedia

2003-01-01

Falling objects and collisions are frequent occurrences in work sites and hazardous areas. Hard hats can help prevent many types of accident and can even save lives. Just imagine an 800 g spanner falling from a 13 m high scaffold onto the head of someone standing below - a nightmare scenario! The impact to the head is equivalent to that of a 5 kg weight falling from 2 metres. That is just what happened to Gerd Fetchenhauer when he was working on the UA1 experiment. Fortunately, he was wearing a hard hat at the time. "That hat saved my life," he explains. "It punched a hole right through the hat and I was a bit dazed for a couple of hours but otherwise I was OK." Since that day, Gerd Fetchenhauer, now working on CMS, is never seen on a work site without his hard hat on. Work sites have proliferated at CERN with the construction of the LHC and its detectors, and the wearing of hard hats is compulsory (not to mention life-saving). In the underground caverns and experiment halls, where gantry cranes and other h...

Cobalt allergy in hard metal workers

Energy Technology Data Exchange (ETDEWEB)

Fischer, T; Rystedt, I

1983-03-01

Hard metal contains about 10% cobalt. 853 hard metal workers were examined and patch tested with substances from their environment. Initial patch tests with 1% cobalt chloride showed 62 positive reactions. By means of secondary serial dilution tests, allergic reactions to cobalt were reproduced in 9 men and 30 women. Weak reactions could not normally be reproduced. A history of hand eczema was found in 36 of the 39 individuals with reproducible positive test reactions to cobalt, while 21 of 23 with a positive initial patch test but negative serial dilution test had never had any skin problems. Hand etching and hand grinding, mainly female activities and traumatic to the hands, were found to involve the greatest risk of cobalt sensitization. 24 individuals had an isolated cobalt allergy. They had probably been sensitized by hard metal work, while the individuals, all women, who had simultaneous nickel allergy had probably been sensitized to nickel before their employment and then became sensitized to cobalt by hard metal work. A traumatic occupation, which causes irritant contact dermatitis and/or a previous contact allergy or atopy is probably a prerequisite for the development of cobalt allergy.

In today's digital age, the increasing dependence on information also makes us vulnerable to potential invasion of privacy and cyber security. Consider a scenario in which a hard drive is stolen, lost, or misplaced, which contains secured and valuable information. In such a case, it is important to have the ability to remotely destroy the sensitive part of the device (e.g., memory or processor) if it is not possible to regain it. Many emerging materials and even some traditional materials like silicon, aluminum, zinc oxide, tungsten, and magnesium, which are often used for logic processor and memory, show promise to be gradually dissolved upon exposure of various liquid medium. However, often these wet processes are too slow, fully destructive, and require assistance from the liquid materials and their suitable availability at the time of need. This study shows Joule heating effect induced thermal expansion and stress gradient between thermally expandable advanced polymeric material and flexible bulk monocrystalline silicon (100) to destroy high-performance solid state electronics as needed and under 10 s. This study also shows different stimuli-assisted smartphone-operated remote destructions of such complementary metal oxide semiconductor electronics.

Full Text Available Nowadays the joint themes of living at the borderland of cultures and responding to the pressures which emerge during the necessary re-formation of identity are treated in an increasing number of literary works. The subject of the present paper is Anne Devlin’s After Easter, a drama which uses the trope of the journey to fuse the constraints of exilic existence with narratives of gender, race and generational tension. My analysis explores how Greta, questor of a new diasporic identity, manages to reinterpret conflicting images and discourses as she confronts them on revisiting her original home country, Troubles-ridden Northern Ireland. By the end of the journey she is able to invent her own story, intertwining concerns of origin and continuity, love of the mother(land as well as of the Other, and through that she re-constructs her identity as a self-assured migrant.

Hard Distraction and Deep Inelastic Scattering

International Nuclear Information System (INIS)

BJORKEN, J.D.

1994-01-01

Since the advent of hard-collision physics, the study of diffractive processes- 'shadow physics' - has been less prominent than before. However, there is now a renewed interest in the subject, especially in that aspect which synthesizes the short-distance, hard-collision phenomena with the classical physics of large rapidity-gaps. This is especially stimulated by the recent data on deep-inelastic scattering from HERA, as well as the theoretical work which relates to it. The word 'diffraction' is sometimes used by high-energy physicists in a loose way. So I here begin by defining what I mean by the term: A diffractive process occurs if and only if there is a large rapidity gap in the produced-particle phase space which is not exponentially suppressed. Here a rapidity gap means essentially no hadrons produced into the rapidity gap (which operates in the 'lego' phase-space of pseudo-rapidity and azimuthal angle). And non-exponential suppression implies that the cross-section for creating a gap with width Δη does not have a power-law decrease with increasing sub energy Δη, but behaves at most like some power of pseudorapidity Δη∼ logs. The term 'hard diffraction' shall simply refer to those diffractive processes which have jets in the final-state phase-space. We may also distinguish, if desired, two subclasses, as suggested by Ingelman i) Diffractive hard processes have jets on only one side of the rapidity gap. ii) Hard diffractive processes have jets on both sides of the rapidity gap

Wave packet autocorrelation functions for quantum hard-disk and hard-sphere billiards in the high-energy, diffraction regime.

Science.gov (United States)

Goussev, Arseni; Dorfman, J R

2006-07-01

We consider the time evolution of a wave packet representing a quantum particle moving in a geometrically open billiard that consists of a number of fixed hard-disk or hard-sphere scatterers. Using the technique of multiple collision expansions we provide a first-principle analytical calculation of the time-dependent autocorrelation function for the wave packet in the high-energy diffraction regime, in which the particle's de Broglie wavelength, while being small compared to the size of the scatterers, is large enough to prevent the formation of geometric shadow over distances of the order of the particle's free flight path. The hard-disk or hard-sphere scattering system must be sufficiently dilute in order for this high-energy diffraction regime to be achievable. Apart from the overall exponential decay, the autocorrelation function exhibits a generally complicated sequence of relatively strong peaks corresponding to partial revivals of the wave packet. Both the exponential decay (or escape) rate and the revival peak structure are predominantly determined by the underlying classical dynamics. A relation between the escape rate, and the Lyapunov exponents and Kolmogorov-Sinai entropy of the counterpart classical system, previously known for hard-disk billiards, is strengthened by generalization to three spatial dimensions. The results of the quantum mechanical calculation of the time-dependent autocorrelation function agree with predictions of the semiclassical periodic orbit theory.

Water Hardness Level and ItAND#8217;s Health Effects

2011-04-01

Full Text Available Water hardness is a term used to define the number of ions contained in the water, especially quantity sulphate, carbonate salts of calcium and magnesium. This characteristis of water is a important quality in it’s use as drinking water, industrial water and service water. The temporary hardness level of water cames from bicarbonate salts of calcium and magnesium whereas chloride, sulphate, nitrate, phosphate, silicate salts of calcium and magnesium. In order to indicate the hardness level of water samples French Hardness Level is used in our country. There is a larger amounth of calcium and magnesium salts in hard water samples. These minerals have very important functions in the human body. In this study, the importance of hard water in terms of human health has been assessed under light of current information. The studies about the preventive role of hard water in cardiovascular diseases, cerebrovascular diseases, stroke and many types of cancer areviewed. These studies Express that higher levels of calcium and magnesium hard water provide a higher reduction in these disease. Water, which must be consumed as 2 liters per dayis very important for human life. Hard water contains a lot of the minerals that must be taker daily, especially calcium and magnesium. It’s advised that water for consumption to have medium hardness. The hardness level of water is an aesthetic quality. Thus, in populations having a taste for soft water, the effort of individuals to softer the network water provided by municipalities using different equipments, in addition to their preference of soft water in plastic or glass bottles for consumption could imply lack of benefit of hard water for population health and also bring out some risks in terms of water hygiene.

The driven self-assembly behaviors of hard nanoplates on soft elastic shells are investigated by using molecular dynamics (MD) simulation method, and the driven self-assembly structures of adsorbed hard nanoplates depend on the shape of hard nanoplates and the bending energy of soft elastic shells. Three main structures for adsorbed hard nanoplates, including the ordered aggregation structures of hard nanoplates for elastic shells with a moderate bending energy, the collapsed structures for elastic shells with a low bending energy, and the disordered aggregation structures for hard shells, are observed. The self-assembly process of adsorbed hard nanoplates is driven by the surface tension of the elastic shell, and the shape of driven self-assembly structures is determined on the basis of the minimization of the second moment of mass distribution. Meanwhile, the deformations of elastic shells can be controlled by the number of adsorbed rods as well as the length of adsorbed rods. This investigation can help us understand the complexity of the driven self-assembly of hard nanoplates on elastic shells. (paper)

Hard template synthesis of metal nanowires

Directory of Open Access Journals (Sweden)

Go eKawamura

2014-11-01

Full Text Available Metal nanowires (NWs have attracted much attention because of their high electron conductivity, optical transmittance and tunable magnetic properties. Metal NWs have been synthesized using soft templates such as surface stabilizing molecules and polymers, and hard templates such as anodic aluminum oxide, mesoporous oxide, carbon nanotubes. NWs prepared from hard templates are composites of metals and the oxide/carbon matrix. Thus, selecting appropriate elements can simplify the production of composite devices. The resulting NWs are immobilized and spatially arranged, as dictated by the ordered porous structure of the template. This avoids the NWs from aggregating, which is common for NWs prepared with soft templates in solution. Herein, the hard template synthesis of metal NWs is reviewed, and the resulting structures, properties and potential applications are discussed.

Joensen, K.D.; Gorenstein, P.; Hoghoj, P.

1997-01-01

Interest in optics for hard X-ray broad-band application is growing. In this paper, we compare the hard X-ray (20-100 keV) reflectivity obtained with an energy-dispersive reflectometer, of a standard commercial gold thin-film with that of a 600 bilayer W/Si X-ray supermirror. The reflectivity...... of the multilayer is found to agree extraordinarily well with theory (assuming an interface roughness of 4.5 Angstrom), while the agreement for the gold film is less, The overall performance of the supermirror is superior to that of gold, extending the band of reflection at least a factor of 2.8 beyond...... that of the gold, Various other design options are discussed, and we conclude that continued interest in the X-ray supermirror for broad-band hard X-ray applications is warranted....

Screw expander for light duty diesel engines

Science.gov (United States)

1983-01-01

Preliminary selection and sizing of a positive displacement screw compressor-expander subsystem for a light-duty adiabatic diesel engine; development of a mathematical model to describe overall efficiencies for the screw compressor and expander; simulation of operation to establish overall efficiency for a range of design parameters and at given engine operating points; simulation to establish potential net power output at light-duty diesel operating points; analytical determination of mass moments of inertia for the rotors and inertia of the compressor-expander subsystem; and preparation of engineering layout drawings of the compressor and expander are discussed. As a result of this work, it was concluded that the screw compressor and expander designed for light-duty diesel engine applications are viable alternatives to turbo-compound systems, with acceptable efficiencies for both units, and only a moderate effect on the transient response.

Tunisian Migrant Journeys: Human Rights Concerns for Tunisians Arriving by Sea

Directory of Open Access Journals (Sweden)

Maegan Hendow

2013-08-01

Full Text Available In part due to its location on the North African coast, in conjunction with its history of being a former French protectorate, Tunisia has become an important country of emigration to the European Union. In particular, maritime arrivals have become a concern for European states, for both humanitarian and security reasons. The experiences of Tunisian irregular migrants arriving to the EU by sea, who are then detained and returned, highlights the multitude of human rights issues that arise across their journey as they interact with the various stakeholders involved—Tunisian and Libyan smugglers, EU and Tunisian authorities and NGOs, amongst others. The situation for these migrants at sea and during rescue and interception operations can most directly involve such issues as the right to life, access to food and water, access to emergency healthcare and access to information. The next stages of detention and return (either immediately or when later identified on EU territory can most directly involve human rights issues related to the identification and referral mechanisms for groups at risk, access to information and legal remedy, the right of “non-refoulement” and prohibition of torture, inhuman and degrading treatment and punishment. By examining Tunisian migrant experiences along the entirety of their trajectory, one can see the specific human rights issues that arise at each stage for maritime arrivals—from departure to return. The article will examine these human rights concerns in the context of the Tunisian migrant journey, focusing on the four identified stages of the situation at sea, rescue or interception, detention and return. The article will present results from qualitative in-depth interviews conducted for the EU Fundamental Rights Agency in 2011 with 15 Tunisian migrants who had arrived by sea to Italy between 2005 and 2011 and were returned to Tunisia between 2008 and 2011, complemented by interviews with two Tunisian

Factorization and non-factorization in diffractive hard scattering

Berera, Arjun

1997-01-01

Factorization, in the sense defined for inclusive hard scattering, is discussed for diffractive hard scattering. A factorization theorem similar to its inclusive counterpart is presented for diffractive DIS. For hadron-hadron diffractive hard scattering, in contrast to its inclusive counterpart, the expected breakdown of factorization is discussed. Cross section estimates are given from a simple field theory model for non-factorizing double-pomeron-exchange (DPE) dijet production with and without account for Sudakov suppression

When a child has chronic pain, it affects the parents. Their response and how it is factored into their lives and family function was the phenomenon of interest that drove this study. The available literature was sparse, especially when the pain etiology was neuropathic. The purpose of this study was to describe the parents' perception of the pain journey from the initial occurrence of their child's pain through the labyrinth of treatment options to successful outcome, to gain a better understanding of parental beliefs about pain, and to learn how parental attitudes and behaviors relate to children's response to treatment for chronic pain. Qualitative descriptive design was used to better understand the phenomenon from those who were the experts because they had experienced it. Parents whose child was enrolled in a pain rehabilitation program participated in open-ended interviews. The children/adolescents were 8-18 years old and diagnosed with complex regional pain syndrome or a related chronic pain condition. During data immersion, the investigators uncovered the pervasive underlying themes of suffering and disempowerment. In addition, the multiple meaning elements were grouped into three categories and supportive subcategories labeled as follows: parent distress, with subcategories schism in parenting, searching, and disabled parenting; and lack of control, with the subcategories family/community, fear, and empowerment. The voices of parents were heard in their description of the exhausting and difficult journey in search of pain relief for their child. Their comments provided insight into how they defined the child's pain and their related parental role. Copyright © 2014 American Society for Pain Management Nursing. Published by Elsevier Inc.

Female and male Hispanic students majoring in science or engineering: Their stories describing their educational journeys

Science.gov (United States)

Brown, Susan Wightman

National statistics clearly demonstrate an underrepresentation of minorities in the fields of science and engineering. Blacks, Hispanics, American Indians, and Asians do not typically choose science or engineering as their college major; therefore, there is a very small representation of these minorities in the science and engineering labor force. The decision not to major in science and engineering may begin as soon as the child can begin to recognize role models in the media. News stories, magazine articles, television programs, teachers, parents, administrators, and other agencies have painted the picture of a scientist or engineer as being dominantly a White male. Schools have continued society's portrayal by using curriculum, textbooks, role models, instructional strategies, and counseling that continues to encourage the White male to succeed in science and engineering, but discourages the minority students, male and female, from succeeding in these fields. In this qualitative study, 22 Hispanic students, 12 female and 10 male, who are majoring in science or engineering, were interviewed using Seidman's in-depth interviewing technique. These students were shadowed in their college science or engineering classes; their high school and college transcripts were analyzed; and, a focus group was brought together at the end of the interviewing process in order to allow interaction between the participants. The goal was to explore the educational journeys of the 22 Hispanic students. What made a difference in the journeys of these 22 students so that they could succeed in majors that have historically discouraged minority students? Seven themes emerged: family support, honors program, challenging and interactive curriculum, college preparation in high school courses, caring and kind teachers, small class size, and small communities. Gender comparison of the educational journeys documents these differences between the females and males: college preparation, mentoring

In the aftermath of an upsurge in the number of dengue cases in 2013 and 2014, the SD BIOLINE Dengue Duo rapid diagnostic Point-of-Care Test (POCT) kit was introduced in Tan Tock Seng Hospital, Singapore in June 2013. It is known that the success of POCT usage is contingent on its implementation within the health system. We evaluated health services delivery and the Dengue Duo rapid diagnostic test kit application in Singapore from healthcare workers' perspectives and patient experiences of dengue at surge times. Focus group discussions were conducted with dengue patients, from before and after the POCT implementation period. In-depth interviews with semi-structured components with healthcare workers were carried out. A patient centred process mapping technique was used for evaluation, which mapped the patient's journey and was mirrored from the healthcare worker's perspective. Patients and healthcare workers confirmed a wide range of symptoms in adults, making it challenging to determine diagnosis. There were multiple routes to help seeking, and no 'typical patient journey', with patients either presenting directly to the hospital emergency department, or being referred there by a primary care provider. Patients groups diagnosed before and after POCT implementation expressed some differences between speed of diagnoses and attitudes of doctors, yet shared negative feelings about waiting times and a lack of communication and poor information delivery. However, the POCT did not in its current implementation do much to help waiting times. Healthcare workers expressed that public perceptions of dengue in recent years was a major factor in changing patient management, and that the POCT kit was helpful in improving the speed and accuracy of diagnoses. Health service delivery for dengue patients in Singapore was overall perceived to be of an acceptable clinical standard, which was enhanced by the introduction of the POCT. However, improvements can be focused on Adapting

Flour quality and kernel hardness connection in winter wheat

Directory of Open Access Journals (Sweden)

Szabó B. P.

2016-12-01

Full Text Available Kernel hardness is controlled by friabilin protein and it depends on the relation between protein matrix and starch granules. Friabilin is present in high concentration in soft grain varieties and in low concentration in hard grain varieties. The high gluten, hard wheat our generally contains about 12.0–13.0% crude protein under Mid-European conditions. The relationship between wheat protein content and kernel texture is usually positive and kernel texture influences the power consumption during milling. Hard-textured wheat grains require more grinding energy than soft-textured grains.

For years, Helen Siu tangoed with history and trekked the fields of South China. "Tracing China: A Forty-Year Ethnographic Journey"(Hong Kong University Press, 2016—a collection of Siu’s work published over the last twenty years—is not a grandiose showpiece splotched with a lot of paint and colors. Instead, she uses a 2B pencil to leave fine marks on wafer-thin parchment and smudges them ever so slightly, gradually letting the image emerge through the back of the page. If I have understood correctly, though plurality exists in the meanings of “trace,” Siu’s intention with the title Tracing China is less to track the history of China, and more to scrupulously examine every footstep she comes across, no matter how indistinct—to “look for plum blossoms in the snow,” as the Chinese saying goes.

Kim, Cholsan; Ju, Hyonhui; Chen, Minghao; Raith, Peter

2015-01-01

The concept of A-coupled-expanding maps is one of the more natural and useful ideas generalized from the horseshoe map which is commonly known as a criterion of chaos. It is well known that distributional chaos is one of the concepts which reflect strong chaotic behavior. In this paper, we focus on the relationship between A-coupled-expanding and distributional chaos. We prove two theorems which give sufficient conditions for a strictly A-coupled-expanding map to be distributionally chaotic in the senses of two kinds, where A is an m × m irreducible transition matrix

Evaluation of hard fossil fuel

Because of its inexhaustible supplies hard fossil fuel will represent the pillar of the power systems of the 21st century. Only high-calorie fossil fuels have the market value and participate in the world trade. Low-calorie fossil fuels ((brown coal and lignite) are fuels spent on the spot and their value is indirectly expressed through manufactured kWh. For the purpose of determining the real value of a tonne of low-calorie coal, the criteria that help in establishing the value of a tonne of hard coal have to be corrected and thus evaluated and assessed at the market.

1978-01-01

We discuss the use of a forward calorimeter to trigger on hard hadron-hadron collisions. We give a derivation in the covariant parton model of the Ochs-Stodolsky scaling law for single-hard-scattering processes, and investigate the conditions when instead a multiple- scattering mechanism might dominate. With a proton beam, this mechanism results in six transverse jets, with a total average multiplicity about twice that seen in ordinary events. We estimate that its cross section is likely to be experimentally accessible at avalues of the beam energy in the region of 100 GeV/c

It has been established that the wear behavior of ceramic materials can be modified through ion implantation. Studies have been done to characterize the effect of implantation on the structure and composition of ceramic surfaces. To understand how these changes affect the wear properties of the ceramic, other mechanical properties must be measured. To accomplish this, a commercially available ultra low load hardness tester has been used to characterize Al 2 O 3 with different implanted species and doses. The hardness of the base material is compared with the highly damaged crystalline state as well as the amorphous material

The purpose of this study was to determine the rate of change in indentation hardness of enamel in permanent teeth exposed to Coca-Cola. In a further experiment, the ability of a commercially available artificial saliva to remineralize enamel treated with Coca-Cola was tested. Ten enamel specimens were randomly chosen to be treated with Coca-Cola (experimental groups) and seven with water (control group). The fluids were applied for 1, 2, 3 h and overnight (15 h), washed off with a few drops of water and the moist enamel indentation hardness tested after each interval. With Coca-Cola treatment, the mean enamel hardness was 92.6% (s.d. = 7.9) of the original baseline hardness after 1 h, 93.25% (s.d. = 10.15) after 2 h, 85.7% (s.d. = 12.03) after 3 h and 80.3% after 15 h. The mean indentation hardness of control specimens treated with water was 108.7% (s.d. = 16.09) of the original hardness after 1 h, 99.09% (s.d. = 18.98) after 2 h, 98.97% (s.d. =11.24) after 3 h and 98.42% (s.d. = 22.78) after 15 h. In a separate experiment, the hardness of 9 enamel specimens was tested, as previously described, before and after treatment with Coca-Cola overnight and again after application of artificial saliva for 3 min. Coca-Cola reduced the mean indentation hardness of enamel in the teeth, but the hardness was partially restored with artificial saliva (Salivart) and increased by 18% from the demineralized enamel hardness.

In this study, the stabilization of the expanded plasma focus formed by 4.5 kJ plasma focus device of Mather type by magnetic field is presented. The experimental results of the induced axial magnetic field and electric probe measurements of the expanded plasma focus show that, the plasma consists of three plasmoids, electron temperature measurements off the plasmoids at a point close to the muzzle are 26 eV, 30 eV and 27 eV respectively and the electron densities are 6.6 x 10 14 , 6.1 x 10 14 / cm 3 respectively. The presence of external axial magnetic field (B 2 = 1.6 kg) at the mid distance between the breech and the muzzle has a less effect on the stability of expanded focus and it causes a restriction for the plasma motion. the electron temperature of the three plasmoids are found to increase in that case by 23%, 18.5% respectively. When this axial magnetic field is applied at the muzzle end, it leads to a more stable expanded plasma focus which consists mainly of one plasmoid with electron temperature of 39 eV and density of 3.4 x 10 14 / cm 3 . 5 figs

Full Text Available This article describes the author's personal journey from childhood to a career in physics. The beauty and truth that the author finds in physics has been the primary driving force and inspiration for her relentless pursuit of knowledge and her constant push for cutting-edge research, despite all obstacles and odds against her as a “double minority” (an Asian woman in a predominantly white male profession. Based on her 20 years of research and teaching at one of the world's leading academic institutions, the California Institute of Technology, the author observes no differences between men and women in their scientific talents, thereby dispelling the misconception of possible inferiority of women as scientists. She further stresses the urgent societal needs for more talent in various sciences to address many of the important issues facing the planet. In this context, society must promote gender equality in science so that one half of the talent does not go to waste. Finally, the author shares her thoughts with young people about how to be better prepared to face the challenges in life and fulfill their dreams.

Peters, C.; Hornberger, G. M.; Machado, M.

2017-12-01

Academics are encouraged to integrate their environmental research with education and societal outreach, but the methods of doing so can be transient and insubstantial. Here, we use a children's book to create a sustainable relationship with vulnerable communities in Bangladesh. Farzana's Journey is a children's book based on current multidisciplinary Vanderbilt University research on the coupling and coevolution of the physical and human systems in coastal Bangladesh. Written, illustrated, and freely distributed in the Bengali-language, the book is a place-based tool to teach rural Bangladesh communities about the natural world and disseminate our scientific findings. The narrative follows a young girl, Farzana, who must walk a long distance to fetch her family's water. Her usual journey develops into an adventure as she meets a variety of animal characters, who relay a story about her ever-changing environment and the subsequent human adaptation. After exploring environmental topics, such as geomorphology, water availability, and climate, Farzana appreciates the uniqueness of her local environment and the adaptations of her ancestors and future generations. Through the development and distribution of the book, we encouraged dialogue, collaboration, and public outreach with scientists, artists, and students concerned with enhancing educational and social opportunity in rural communities. We also ensure a tangible tie through the book itself after the culmination of the research project. The book achieves the primary goal of sparking children's curiosity in the local environment, while also demonstrating an effective means for sustainable educational outreach with impoverished, remote communities.

In 2015, more than 1 million refugees arrived in Europe. During their travels, refugees often face harsh conditions, violence and torture in transit countries, but there is a lack of quantitative evidence on their experiences. We present the results of a retrospective survey among refugees in the 'Jungle' of Calais, France, to document their health problems and the violence they endured during their journeys. We conducted a cross-sectional population-based survey in November and December 2015. The sample size was set at 402 individuals, and geospatial simple random sampling was used. We collected data on demographics, routes travelled, health status, violence and future plans. Departures from the country of origin increased beginning in September 2015. Sixty-one percent of respondents reported having at least one health problem, especially while in Calais. Overall, 65.6% (95% CI 60.3-70.6) experienced at least one violent event en route; 81.5% of refugees wanted to go to the UK. This first quantitative survey conducted among refugees in Europe provides important socio-demographic data on refugees living in Calais and describes the high rate of violence they encountered during their journeys. Similar documentation should be repeated throughout Europe in order to better respond to the needs of this vulnerable population. © The Author 2017.

Zirconium based alloys are the natural choice for both the fuel element cans and in-core structural components in water cooled nuclear reactors. In this paper, the hot hardness behaviour of zircaloy 2 pressure tubes has been examined from room temperature to 400 degC using a hot hardness tester. For the purpose of comparison, the hardness of the as cast and room temperature rolled specimens has also been carried out. For this, the samples were cut along three orientations and hardness was measured in each of these directions using Vickers diamond pyramid indenter. The variation in hardness of the pressure tube samples show that the hardness was highest along circumferential direction and least along the axial direction. The room temperature rolled samples showed highest hardness along the rolling planes. These variations in hardness could be explained in terms of development of texture during working on the material. (author)

From 2001 to 2006, 139 patients (age, 62.1 +/- 15.4 years; range, 23-87 years) with benign (n = 62) and malignant (n = 77) tracheobronchial disease received 192 Ultraflex (Boston Scientific, Natick, Mass) self-expandable metallic stents (98 in patients with benign disease and 94 in patients with malignant disease). Seventeen fractured self-expandable metallic stents were found; the incidence was 12.2% (17/139 patients) among patients with tracheobronchial disease. Tortuous airway (odds ratio, 4.06; 95% confidence interval, 1.04-18.34; P = .04) independently predicted self-expandable metallic stent fracture. Most self-expandable metallic stent fractures (64.7%, 11/17) were detected 500 to 1000 days after self-expandable metallic stent implantation. Clinical presentations for patients with fractured self-expandable metallic stents included dyspnea exacerbation (70.6%, 12/17) and cough (23.5%, 4/17). Self-expandable metallic stent fracture is not uncommon in patients with tracheobronchial disease. Tortuous airway is an independent predictor for it. Although management of the fractured self-expandable metallic stent in our study was feasible and safe, self-expandable metallic stents should be restricted to a more select population.

Neutrinos in an expanding Universe

International Nuclear Information System (INIS)

Wigmans, Richard

2015-01-01

The Universe contains several billion neutrinos for each nucleon. In this paper, we follow the history of these relic neutrinos as the Universe expanded. At present, their typical velocity is a few hundred km/s and, therefore, their spectra are affected by gravitational forces. This may have led to a phenomenon that could explain two of todays great mysteries: The large-scale structure of the Universe and the increasing rate at which it expands. (paper)

2012-02-01

Full Text Available This study evaluated the effect of artificially accelerated aging (AAA on the surface hardness of eight composite resins: Filtek Z250, Filtek Supreme, 4 Seasons, Herculite, P60, Tetric Ceram, Charisma, and Filtek Z100. Sixteen specimens were made from the test piece of each material, using an 8.0 × 2.0 mm teflon matrix. After 24 hours, eight specimens from each material were submitted to three surface hardness readings using a Shimadzu Microhardness Tester for 5 seconds at a load of 50 gf. The other eight specimens remained in the artificially accelerated aging machine for 382 hours and were submitted to the same surface hardness analysis. The means of each test specimen were submitted to the Kolmogorov-Smirnov test (p > 0.05, ANOVA and Tukey test (p < 0.05. With regard to hardness (F = 86.74, p < 0.0001 the analysis showed significant differences among the resin composite brands. But aging did not influence the hardness of any of the resin composites (F = 0.39, p = 0.53. In this study, there was interaction between the resin composite brand and the aging factors (F = 4.51, p < 0.0002. It was concluded that notwithstanding the type of resin, AAA did not influence surface hardness. However, with regard to hardness there was a significant difference among the resin brands.

Full Text Available Questo articolo riguarda principalmente la natura delle tecnologie per apprendere, con una particolare attenzione ai social media. Muovendo dalla definizione fornita da W. Brian Arthur delle tecnologie come un insieme di fenomeni orchestrati per un qualche uso, l’articolo amplia la teoria di Arthur ridefinendo e allargando la distinzione comunemente accettata tra tecnologie soft e hard, laddove le tecnologie soft sono intese come quelle che richiedono l’orchestrazione di fenomeni da parte degli esseri umani, mentre le tecnologie hard sono quelle per le quali l’orchestrazione è predeterminata o incorporata. Le tecnologie per apprendere sono quelle in cui le pedagogie (anch’esse tecnologie sono parte dell’insieme. Le conseguenze di questa prospettiva vengono esplorate nel quadro di diversi modelli pedagogici e in relazione agli approcci basati sul social learning in una varietà di contesti, dai corsi per corrispondenza ai MOOC.

Pipe, Teresa Britt

2008-01-01

Sustained, high-performance nursing leadership can be effectively guided by caring theory. While much of leadership performance is manifested by external behaviors, highly effective leaders are also grounded by internal work of self-reflection and growth. This article focuses primarily on the inward journey of leadership as guided by Jean Watson's Theory of Human Caring. Key elements of the theory are interpreted within the context of the emerging, urgent, high-stakes challenges of the current healthcare environment. The links between self-nurturance and caring-healing leadership of others are explored.

Dependence of Hardness of Silicate Glasses on Composition and Thermal History

composition on hardness of silicate glasses. E-glasses of different compositions are subjected to various degrees of annealing to obtain various fictive temperatures in the glasses. It is found that hardness decreases with the fictive temperature. Addition of Na2O to a SiO2-Al2O3-Na2O glass system causes......The prediction of hardness is possible for crystalline materials, but so far not possible for glasses. In this work, several important factors that should be used for predicting the hardness of glasses are discussed. To do so, we have studied the influences of thermal history and chemical...... a decrease in hardness. However, hardness cannot solely be determined from the degree of polymerisation of the glass network. It is also determined by the effect of ionic radius on hardness. However, this effect has opposite trend for alkali and alkaline earth ions. The hardness increases with ionic radius...

In this work nitrided layers deposited on austenitic and super austenitic stainless steels were analyzed through optical microscopy and X-rays diffraction analysis (XRD). It was observed that the formation of N supersaturated phase, called expanded austenite, has promoted significant increment of hardness (> 1000HV). XRD results have indicated the anomalous displacement of the diffracted peaks, in comparison with the normal austenite. This behavior, combined with peaks broadening, it was analyzed in different nitriding temperatures which results showed good agreement with the literature. (author)

Playing Moderately Hard to Get

Directory of Open Access Journals (Sweden)

Stephen Reysen

2013-12-01

Full Text Available In two studies, we examined the effect of different degrees of attraction reciprocation on ratings of attraction toward a potential romantic partner. Undergraduate college student participants imagined a potential romantic partner who reciprocated a low (reciprocating attraction one day a week, moderate (reciprocating attraction three days a week, high (reciprocating attraction five days a week, or unspecified degree of attraction (no mention of reciprocation. Participants then rated their degree of attraction toward the potential partner. The results of Study 1 provided only partial support for Brehm’s emotion intensity theory. However, after revising the high reciprocation condition vignette in Study 2, supporting Brehm’s emotion intensity theory, results show that a potential partners’ display of reciprocation of attraction acted as a deterrent to participants’ intensity of experienced attraction to the potential partner. The results support the notion that playing moderately hard to get elicits more intense feelings of attraction from potential suitors than playing too easy or too hard to get. Discussion of previous research examining playing hard to get is also re-examined through an emotion intensity theory theoretical lens.

Free-piston reciprocating cryogenic expander utilizing phase controller

Science.gov (United States)

Cha, Jeongmin; Park, Jiho; Kim, Kyungjoong; Jeong, Sangkwon

2017-02-01

In a free-piston expander which eliminates mechanical linkages, a prescribed behaviour of the free-piston movement is the key to an expander performance. In this paper, we have proposed an idea of reducing complexity of the free-piston expander. It is to replace both multiple solenoid valves and reservoirs that are indispensable in a previous machine with a combination of a single orifice-reservoir assembly. It functions as a phase controller like that of a pulse tube refrigerator so that it generates time-delay of pressure variation between the warm-end and the reservoir resulting in the intended expansion of the cold-end volume down to the pre-set reservoir pressure. The modeling of this unique free-piston reciprocating expander utilizing phase controller is developed to understand and predict the performance of the new-type expander. Additionally, the operating parameters are analysed at the specified conditions to enable one to develop a more efficient free-piston type cryogenic expander.

Close, Frank

2017-01-01

On August 21st, over one hundred million people will gather across the USA to witness the most-watched total solar eclipse in history. Eclipse: Journeys to the Dark Side of the Moon, by popular science author Frank Close, describes the spellbinding allure of this beautiful natural phenomenon. The book explains why eclipses happen, reveals their role in history, literature and myth, and introduces us to eclipse chasers, who travel with ecstatic fervor to some of the most inaccessible places on the globe. The book also includes the author's quest to solve a 3000-year-old mystery: how did the moon move backward during a total solar eclipse, as claimed in the Book of Joshua? Eclipse is also the story of how a teacher inspired the author, aged eight, to pursue a career in science and a love affair with eclipses that has taken him to a war zone in the Western Sahara, the South Pacific, and the African bush. The tale comes full circle with another eight-year old boy - the author's grandson - at the 2017 great Americ...

In this thesis work the synthesis of thin films of titanium nitride (TiN), amorphous carbon nitride (CN x ) amorphous carbon (a-C) and Ti/TiN/CNx multilayers and Ti/TiN/a-C by means of the laser ablation technique, with the objective of obtaining films of high hardness is studied, as well as to produce multilayer coatings with superior properties to the individual layers. The effect that has the laser fluence used for ablationing the targets in the structure and mechanical properties of the films deposited of TiN was investigated. It was found that the hardness is increased in lineal way approximately with the fluence increment up to 19 J/cm 2 . Thin films of a-C with hardness of the order of 12 GPa. likewise CN x films with high hardness (18.4 GPa) were obtained. The hardness of the deposited films was analyzed and it was related with its microstructure and deposit conditions. It was concluded that the Ti/TiN/CNx and Ti/TiN/a-C systems presented bigger hardness that of its individual components. (Author)

Sampling from a polytope and hard-disk Monte Carlo

International Nuclear Information System (INIS)

Kapfer, Sebastian C; Krauth, Werner

2013-01-01

The hard-disk problem, the statics and the dynamics of equal two-dimensional hard spheres in a periodic box, has had a profound influence on statistical and computational physics. Markov-chain Monte Carlo and molecular dynamics were first discussed for this model. Here we reformulate hard-disk Monte Carlo algorithms in terms of another classic problem, namely the sampling from a polytope. Local Markov-chain Monte Carlo, as proposed by Metropolis et al. in 1953, appears as a sequence of random walks in high-dimensional polytopes, while the moves of the more powerful event-chain algorithm correspond to molecular dynamics evolution. We determine the convergence properties of Monte Carlo methods in a special invariant polytope associated with hard-disk configurations, and the implications for convergence of hard-disk sampling. Finally, we discuss parallelization strategies for event-chain Monte Carlo and present results for a multicore implementation

The over-the-limb hard X-ray events

Science.gov (United States)

Hudson, H. S.

Over-the-limb hard X-ray events offer a uniquely direct view of the hard X-ray emission from the solar corona during a major flare. Limb occultation at angles greater than about 10 deg (an arbitrary definition of this class of events) excludes any confusion with brighter chromospheric sources. Published observations of seven over-the-limb events, beginning with the prototype flare of March 30, 1969, are reviewed. The hard X-ray spectra appear to fall into two classes: hard events, with power-law index of about 2.0; and soft events, with power-law index about 5.4. This tendency towards bimodality is only significant at the 90-percent confidence level due to the smallness of the number of events observed to date. If borne out by future data, the bimodality would suggest the existence of two different acceleration mechanisms.

Constraint satisfaction problems with isolated solutions are hard

International Nuclear Information System (INIS)

Zdeborová, Lenka; Mézard, Marc

2008-01-01

We study the phase diagram and the algorithmic hardness of the random 'locked' constraint satisfaction problems, and compare them to the commonly studied 'non-locked' problems like satisfiability of Boolean formulae or graph coloring. The special property of the locked problems is that clusters of solutions are isolated points. This simplifies significantly the determination of the phase diagram, which makes the locked problems particularly appealing from the mathematical point of view. On the other hand, we show empirically that the clustered phase of these problems is extremely hard from the algorithmic point of view: the best known algorithms all fail to find solutions. Our results suggest that the easy/hard transition (for currently known algorithms) in the locked problems coincides with the clustering transition. These should thus be regarded as new benchmarks of really hard constraint satisfaction problems

A healthful experience? A patient practice development journey

2016-05-01

Full Text Available While facilitating the first practice development school for our local healthcare authorities in Nova Scotia, Canada, recently, I was simultaneously preparing for my second hip replacement. Focusing workshop participants on the principles of practice development, collaboration, inclusion and participation, I wondered if, in my upcoming journey through the healthcare system, I would experience the processes and outcomes we were promoting in the school. I would like to share this commentary as a reflection of my practice development experience as a patient. Overall, I received care that was inclusive and collaborative – as well as care that was provider focused and system driven. It goes without saying that as a patient, I felt valued when I was included and felt part of the team when my wishes and expectations were taken into consideration. For me, inclusion in care correlates with valuing that patient as a participant in their care journey, as set out by practice development principle 6 (Manley, McCormack and Wilson, 2008 (Table 1. My recent healthcare experience has led me to reflect further on the principles of practice development and its implications and challenges for local healthcare authorities. For example, my anaesthetist comes to mind as embodying practice development principles 2, 4, 6 and 8. The anaesthetist supported my wishes surrounding narcotics, and provided research- and practice-based evidence for each of his actions. Although the offering of additional narcotics is routine practice in hip surgery, I did not want this, so we discussed my expectations and developed a plan together that reflected my wishes. He actually chatted throughout the entire two-hour procedure. I was pleasantly surprised when he told me he provides care that focuses on the patient (practice development principle 1. Nevertheless, inconsistencies in the attention to person-centred practices across the microsystem reminded me that the system is not yet set

Hard scattering and gauge/string duality

International Nuclear Information System (INIS)

Polchinski, Joseph; Strassler, Matthew J.

2002-01-01

We consider high-energy fixed-angle scattering of glueballs in confining gauge theories that have supergravity duals. Although the effective description is in terms of the scattering of strings, we find that the amplitudes are hard (power law). This is a consequence of the warped geometry of the dual theory, which has the effect that in an inertial frame the string process is never in the soft regime. At small angle we find hard and Regge behaviors in different kinematic regions

We measured the radiation hardness of undoped BGO crystals from two different manufacturers. Such crystals are proposed to be used in a small-angle calorimeter of the BELLE detector of the KEK B-factory. Transparency and scintillation light output of the crystals were monitored to see the effect of radiation damage. The crystals show considerable radiation hardness up to 10.2 Mrad equivalent dose, which is much higher than the maximum expected dosage of 500 krad per year of running at BELLE. (orig.)

2001-01-01

The high-energy behaviour of two-scale hard processes is investigated in the framework of small-x models with running coupling, having the Airy diffusion model as prototype. We show that, in some intermediate high-energy regime, the perturbative hard Pomeron exponent determines the energy dependence, and we prove that diffusion corrections have the form hinted at before in particular cases. We also discuss the breakdown of such regime at very large energies, and the onset of the non-perturbative Pomeron behaviour.

Positron beams: The journey from fundamental physics to industrial application

Coleman, P.G.

2002-01-01

Monoenergetic beams of positrons developed for fundamental atomic physics experiments have evolved - via basic and applied research in condensed matter physics and chemistry - to a phase in which possibilities for commercial exploitation are becoming apparent. The evolution of positron beam technology, from table-top laboratory-based apparatus with positrons of energies controllable in the 10 0 -10 2 eV energy range and beam intensities of ∼1 s -1 , to systems capable of delivering positrons of energies from 0.02 eV to MeV at intensities as high as 10 8 s -1 , has been both steady and saltatory. The journey from fundamental research to industrial application is a classic example of scientific development; a brief summary of steps on the way is followed by an example in which an attempt is being made to harness the efficacy of positron beams applied to defect spectroscopy of semiconductor structures to create an instrument of value to the ion implantation industry

Howie, John G R

2014-02-01

This essay is a personal review of a research journey extending over 50 years during which time the understanding of medical practice has changed out of all recognition and the quality and standing of the discipline of general practice has improved substantially. Three main bodies of work are reviewed and set against the reasons why they were undertaken. The first, on the pathology of the appendix and the management of possible appendicitis, was carried out almost entirely in the hospital setting. The second, about the prescribing of antibiotics for respiratory illnesses, and the third, about the determinants of good consulting practice, were carried out in general practice. The essay concludes with a reflection on the relevance of the work to some contemporary academic and health service issues. Although the work was carried out in the UK in the context of its National Health Service (NHS), the conclusions are widely generalizable and have contributed to health service and academic developments in many other countries.

A short journey from quarks to the universe. Selected solutions

Energy Technology Data Exchange (ETDEWEB)

Economou, Eleftherios N. [Foundation for Research and Technology Hellas (FORTH), Iraklion (GR). Inst. of Electronic Structure and Laser (IESL)

2011-07-01

This book takes the reader for a short journey over the structures of matter showing that their main properties can be obtained even at a quantitative level with a minimum background knowledge. The latter, besides some high school physics and mathematics, consists of the three cornerstones of science presented in chapters 1 to 3, namely the atomic idea, the wave-particle duality, and the minimization of energy as the condition for equilibrium. Dimensional analysis employing the universal constants and combined with ''a little imagination and thinking'', to quote Feynman, allows an amazing short-cut derivation of several quantitative results concerning the structures of matter. This book is expected to be of interest to physics, engineering, and other science students and to researchers in physics, material science, chemistry, and engineering who may find stimulating the alternative derivation of several real world results, which sometimes seem to pop out the magician's hat.

Particle production at large transverse momentum and hard collision models

International Nuclear Information System (INIS)

Ranft, G.; Ranft, J.

1977-04-01

The majority of the presently available experimental data is consistent with hard scattering models. Therefore the hard scattering model seems to be well established. There is good evidence for jets in large transverse momentum reactions as predicted by these models. The overall picture is however not yet well enough understood. We mention only the empirical hard scattering cross section introduced in most of the models, the lack of a deep theoretical understanding of the interplay between quark confinement and jet production, and the fact that we are not yet able to discriminate conclusively between the many proposed hard scattering models. The status of different hard collision models discussed in this paper is summarized. (author)

Hard wheat (HW), medium-hard wheat (MHW) and extraordinarily soft wheat (Ex-SW) varieties with grain hardness index (GHI) of 83 to 95, 72 to 80, 17 to 29 were evaluated for pasting, protein molecular weight (MW) distribution, dough rheology and baking properties. Flours from varieties with higher GHI had more protein content, ash content and paste viscosities. Ex-SW had more glutenins proportion as compared to HW and MHW. Flours from Ex-SW varieties showed lower NaSRC, WA and mixographic parameters as compared to HW and MHW. Dough from flours milled from Ex-SW had higher Intermolecular-β-sheets (IM-β-sheets) than those from MHW and HW. Muffins volume increased with decrease in GHI, Ex-SW varieties had more muffin volume and less air space. The accumulation of polypeptides (PPs) varied significantly in different varieties. Ex-SW variety (QBP12-10) showed accumulation of 98, 90, 81 and 79kDa PPs, which was unique and was different from other varieties. Copyright © 2017 Elsevier Ltd. All rights reserved.

The properties of hard coatings deposited using CVD processes are usually excellent. However, high deposition temperatures negatively influence the substrate properties, especially in the case of low alloyed steels. Therefore, a subsequent heat treatment is necessary to restore the properties of steel substrates. Here, induction surface hardening is used as a method of heat treatment after the deposition of TiN hard coatings on AISI 4140 (DIN42CrMo4) substrates. The influences of the heat treatment on both the coating and the substrate properties are discussed in relation to the parameters of induction heating. Thereby, the heating time, heating atmosphere and the power input into the coating-substrate compounds are varied. As a result of induction surface hardening, the properties of the substrates are improved without losing good coating properties. High hardness values in the substrate near the interface allow the AISI 4140 substrates to support TiN hard coatings very well. Consequently, higher critical loads are measured in scratch tests after the heat treatment. Also, compressive residual stresses in the substrate are generated. In addition, only a very low distortion appears. (orig.)

Electroplated hard chrome coating is widely used as a wear resistant coating to prolong the life of mechanical components. However, the electroplating process generates hexavalent chromium ion which is known carcinogen. Hence, there is a major effort throughout the electroplating industry to replace hard chrome coating. Composite coating has been identified as suitable materials for replacement of hard chrome coating, while deposition coating prepared using traditional co-deposition techniques have relatively low particles content, but the content of particles incorporated into a coating may fundamentally affect its properties. In the present work, Ni-W/diamond composite coatings were prepared by sediment co-electrodeposition from Ni-W plating bath, containing suspended diamond particles. This study indicates that higher diamond contents could be successfully co-deposited and uniformly distributed in the Ni-W alloy matrix. The maximum hardness of Ni-W/diamond composite coatings is found to be 2249 ± 23 Hv due to the highest diamond content of 64 wt.%. The hardness could be further enhanced up to 2647 ± 25 Hv with heat treatment at 873 K for 1 h in Ar gas, which is comparable to hard chrome coatings. Moreover, the addition of diamond particles could significantly enhance the wear resistance of the coatings.

On becoming a consultant: A study exploring the journey to consultant practice

International Nuclear Information System (INIS)

Henwood, S.; Booth, L.

2016-01-01

Background: This paper reports a qualitative study exploring the establishment of non-medical consultant roles in Radiography. Given the difficulties reported in recruiting and retaining staff in these posts, we hope this paper offers a historical documentation of those consultants who were some of the first in post, sharing their stories of how they obtained and transitioned into their roles. Methods: This paper is part of a two year case study exploring the leadership domain of consultant practice. The focus of this paper is a reflection, by the consultants, of their journey to becoming a consultant; a documentation of some of the practical issues in establishing the roles; and the transition to higher levels of practice. Eight consultant radiographers participated in the initial interviews (two consultants withdrew from the study subsequent to this). In-depth iterative interviewing was used to explore and record individual stories and experiences. Findings: The consultants shared their perceptions of being in post, including their own motivation to progress to a new role, how prepared they felt initially, the lack of role models, the lack of clarity surrounding the role and a perception of ‘being on display’. Conclusions: The paper offers insight into the journey of these consultants and some of the common characteristics they share. These characteristics give some indication of what motivated them to step into higher level roles, in particular the need to drive change and improvement. The paper also offers suggestions for how the transition into the role could be more effectively supported. - Highlights: • Identifies characteristics thought to contribute to effective consultant practice. • A desire to change practice is a major motivator in applying for a consultant post. • The consultant role was a natural evolution for some, not a desired career pathway. • There is recognition that the initial consultants were pioneers for the profession. �

Elasticity of Hard-Spheres-And-Tether Systems

International Nuclear Information System (INIS)

Farago, O.; Kantor, Y.

Physical properties of a large class of systems ranging from noble gases to polymers and rubber are primarily determined by entropy, while the internal energy plays a minor role. Such systems can be conveniently modeled and numerically studied using ''hard' (i.e., ''infinity-or-zero'') potentials, such as hard sphere repulsive interactions, or inextensible (''tether'') bonds which limit the distance between the bonded monomers, but have zero energy at all permitted distances. The knowledge of elastic constants is very important for understanding the behavior of entropy-dominated systems. Computational methods for determination of the elastic constants in such systems are broadly classified into ''strain'' methods and (fluctuation methods. In the former, the elastic constants are extracted from stress-strain relations, while in the latter they are determined from measurements of stress fluctuations. The fluctuation technique usually enables more accurate and well-controlled determination of the elastic constants since in this method the elastic constants are computed directly from simulations of the un strained system with no need to deform the simulation cell and perform numerical differentiations. For central forces systems, the original ''fluctuation'' formalism can be applied provided the pair potential is twice differentiable. We have extended this formalism to apply to hard-spheres-and-tether models in which this requirement is not fulfilled. We found that for such models the components of the tensor of elastic constants can be related to (two-, three- and four-point) probability densities of contacts between hard spheres and stretched bonds. We have tested our formalism on simple (phantom networks and three-dimensional hard spheres systems

Characteristics of hard X-ray double sources in impulsive solar flares

Imaging observations of solar flare hard X-ray sources with the Hard X-ray Telescope (HXT) aboard the Yohkoh satellite have revealed that hard X-ray emissions (greater than 30 ke V) originate most frequently from double sources. The double sources are located on both sides of the magnetic neutral line, suggesting that the bulk of hard X-rays is emitted from footpoints of flaring magnetic loops. We also found that hard X-rays from the double sources are emitted simultaneously within a fraction of second and that the weaker source tends to be located in the stronger magnetic field region, showing a softer spectrum. Physcial implications on the observed characteristics of the hard X-ray double sources are discussed.

Schroeter, W.

1981-01-01

Intermetallic compounds of metals with non-metals such as C, N, and B show different hardness. Wagner's interaction parameter characterizes manner and extent of the interaction between the atoms of the substance dissolved and the additional elements in metallic mixed phases. An attempt has been made to correlate the hardness of carbides, nitrides, and borides (data taken from literature) with certain interaction parameters and associated thermodynamic quantities (ΔH, ΔG). For some metals of periods 4, 5, and 6 corresponding relations were found between microhardness, interaction parameters, heat of formation, and atomic number

The horizontal sinter-HIP equipment with great charge capacity and high performance, developed and manufactured by Central Iron and Steel Research Institute(CISRI), is mainly used for sintering and condensation of hard metals. This equipment is characterized by large hot zone, high heating speed, good temperature uniformity and fast cooling system. The equipment can provide uniform hot zone with temperature difference less than 6 o C at 1500-1600 o C and 6-10 MPa by controlling temperature, pressure and circulation of gas precisely. Using large scale horizontal sinter-HIP equipment to produce hard matals have many advantages such as stable quality, high efficiency of production, high rate of finished products and low production cost, so this equipment is a good choice for manufacturer of hard metals.

2016-12-01

Full Text Available The paper discusses Homeric motifs in ‘Priam’s Night Journey’, a poem by the contemporary Greek poet Constantine P. Cavafy and, more precisely, one of the ten poems composed by Cavafy on mythological themes. The discussion begins by comparing Cavafy’s treatment of a motif from the Iliad, Canto 24 – Priam’s journey to Achilles – with its ancient counterpart. The question of Cavafy’s sources is addressed as well: does the poet draw on the Ancient Greek original or on the Modern Greek translation? The second part of the article analyses in detail those passages which closely lean on the ancient epic, and concludes by illustrating Cavafy’s departure from the myth, which emerges most radically in the close of the poem.

Hard Times as Bodie: the allegorical functionality in E.L. Doctorow’s Welcome to Hard Times (1960

Directory of Open Access Journals (Sweden)

P. van der Merwe

2007-07-01

Full Text Available “Welcome to Hard Times” (1960, E.L. Doctorow’s first novel, differs from the rest of his oeuvre because it is not set in a metropolitan context like New York. References to historical events that contain an apparent “mixture” of “factual” and fictional elements that are typical of Doctorow’s oeuvre are less prominent than in his other fiction, though definitely not absent. An analysis of the pioneer setting, the town Hard Times, reveals that other settings (including metropolitan ones like New York are not merely representations of specific contexts, but portrayals with allegorical elements. Criticism of Doctorow’s fiction does not sufficiently point out the rationale of Doctorow’s fiction in relation to his first novel: it is not just the basic level that contains the true topicality but also the underlying causal and thematic relationships. This article sets out to explore “Welcome to Hard Times” as a case in point. The objective of this article is therefore also to show that an analysis of this novel provides a valuable basis for understanding the allegorical character of his fiction. Angus Fletcher’s theoretical analysis, “Allegory: the theory of a symbolic mode” (1964, serves as a useful starting point for the analysis of the allegorical value of space and the town Hard Times as a microcosmic or symbolic society, as well as the “daemonic agents” in the town and the role of causality.

The Pre-Raphaelite Journey into the Middle Ages

Full Text Available The Pre-Raphaelite artists and poets rejected contemporary conventional style in art, and did not concern themselves with the representation of contemporary life either. They viewed the surrounding social life as sordid, and reached back to the Middle Ages both for technique and subject matter. Dante Gabriel Rossetti, Holman Hunt, John Everett Millais, and later William Morris found inspiration in late medieval art and literature. They took their subjects from history, legend, religion or poetry, focusing on moral or psychological issues, and expressed fascination for beauty as a value of spiritual nature. This paper examines three of Dante Gabriel Rossetti’s medieval fantasy pictures (The Tune of Seven Towers, The Blue Closet and A Christmas Carol, which prompt a meditative and imaginative response through their enigmatic references, and thus attest the mysterious feature of Pre-Raphaelite medieval imagery. The paper discusses their enigmatic nature in the light of William Morris’s early dream poems The Tune of Seven Towers and The Blue Closet, written on the relevant Rossetti pictures. A parallel reading of poem and picture evidences how Pre-Raphaelite medievalism in painting can invite the onlooker for an inner journey through exploring an imagined referential background.

Highlights: • Post-implant geometry of catheter-based aortic valve prostheses is influenced by aortic valve calcification. • Balloon-expandable prostheses are more circular as compared to self-expanding prostheses. • The impact of post-implant geometry on valve function needs to be investigated. - Abstract: Introduction: The geometry of the aortic annulus and implanted transcatheter aortic valve prosthesis might influence valve function. We investigated the influence of valve type and aortic valve calcification on post-implant geometry of catheter-based aortic valve prostheses. Methods: Eighty consecutive patients with severe aortic valve stenosis (mean age 82 ± 6 years) underwent computed tomography before and after TAVI. Aortic annulus diameters were determined. Influence of prosthesis type and degree of aortic valve calcification on post-implant eccentricity were analysed. Results: Aortic annulus eccentricity was reduced in patients after TAVI (0.21 ± 0.06 vs. 0.08 ± 0.06, p < 0.0001). Post-TAVI eccentricity was significantly lower in 65 patients following implantation of a balloon-expandable prosthesis as compared to 15 patients who received a self-expanding prosthesis (0.06 ± 0.05 vs. 0.15 ± 0.07, p < 0.0001), even though the extent of aortic valve calcification was not different. After TAVI, patients with a higher calcium amount retained a significantly higher eccentricity compared to patients with lower amounts of calcium. Conclusions: Patients undergoing TAVI with a balloon-expandable prosthesis show a more circular shape of the implanted prosthesis as compared to patients with a self-expanding prosthesis. Eccentricity of the deployed prosthesis is affected by the extent of aortic valve calcification

Transition from reversible to irreversible magnetic exchange-spring processes in antiferromagnetically exchange-coupled hard/soft/hard trilayer structures

2011-01-01

The demagnetization processes of antiferromagnetically exchange-coupled hard/soft/hard trilayer structures have been studied based on the discrete one-dimensional atomic chain model and the linear partial domain-wall model. It is found that, when the magnetic anisotropy of soft layer is taken into account, the changes of the soft layer thickness and the interfacial exchange coupling strength may lead a transition of demagnetization process in soft layer from the reversible to the irreversible magnetic exchange-spring process. For the trilayer structures with very thin soft layer, the demagnetization process exhibits typical reversible exchange-spring behavior. However, as the thickness of soft layer is increased, there is a crossover point t c , after which the process becomes irreversible. Similarly, there is also a critical interfacial exchange coupling constant A sh c , above which the exchange-spring process is reversible. When A sh sh c , the irreversible exchange-spring process is achieved. The phase diagram of reversible and irreversible exchange-spring processes is mapped in the plane of the interfacial exchange coupling A sh and soft layer thickness N s . - Research highlights: → A differing magnetic exchange-spring process is found in antiferromagnetically exchange-coupled hard/soft/hard trilayers if the magnetic anisotropy of the soft layers is taken into account. → The change of the soft layer thickness may lead to a transition of demagnetization process in soft layer from the reversible to the irreversible exchange-spring process. → The change of the soft-hard interfacial exchange coupling strength may lead a transition of demagnetization process in soft layer from the reversible to the irreversible exchange-spring process. → The phase diagram of reversible and irreversible exchange-spring processes is mapped in the plane of the interfacial exchange coupling and soft layer thickness.
