Abstract:
AbstractBackgroundAt present, the exclusion for percutaneous pulmonary valve implantation for free pulmonary regurgitation after tetralogy of Fallot repair includes an unfavourably large right ventricular outflow tract.ObjectiveTo report feasibility and early experience with a recently developed transcatheter heart valve, Venus P-valveTM, implanted in six patients with severe pulmonary regurgitation with large right ventricular outflow tracts.PatientsThere were two female patients and four male patients. The median age of the patients was 18.5 years, and the mean body weight was 53.8 kg. All the patients were in NYHA class II and had severe pulmonary regurgitation after previous transannular patch repair of tetralogy of Fallot. The median time after the last surgical operation was 13.5 years.ResultsThe Venus P-valveTM was successfully implanted in all the patients with implanted valve diameters ranging from 24 to 32 mm. The mean fluoroscopy time was 29.8 minutes. None of the patients had significant outflow tract gradient or pulmonary regurgitation immediately after valve implantation. Only one patient had unexpected mild proximal valve migration to the right ventricular body during withdrawal of the delivery system. It caused mild paravalvar leak and significant tricuspid regurgitation. At 6 months follow-up, the median of right ventricular end-diastolic volume indices decreased from 146 to 108 ml/m2 (p-value=0.046). The Doppler systolic peak gradient across the valve ranged from 4 to 40 mmHg, and there was no evidence of stent fracture on fluoroscopy or structural valve failure.ConclusionThe Venus P-valveTM can be implanted successfully and effectively in patients with severe pulmonary regurgitation and a large right ventricular outflow tract. The early results with this valve are encouraging.

Abstract:
Percutaneous treatment of severe mitral regurgitation is a very interesting therapeutic option for those patients considered not to be suitable candidates for surgery. Different technologies have already demonstrated proof-of-concept, and one of these devices (the Mitraclip device) has already obtained the Conformité Europeéne mark. However, demonstrating safety and efficacy for most of these technologies is being harder than anticipated. Recently, research and development has become more compromised due to the financial crisis. This paper reviews the venues that are currently under evaluation.

Abstract:
This is the story of a rock venue in an English city. Hardly, it might be supposed, the stuff of great drama; there are, after all, rock venues throughout England. Most towns and cities of any size have at least one. But this venue, the Waterfront in Norwich, is distinctive, if not unique, in at least two respects.It was purpose-built and, more importantly, it was largely financed, not by private enterprise, but by the city's Labour council. Norwich's local politicians risked both financial and political capital so that their city could host performers like Nitzer Ebb, Dumpy's Rusty Nuts, Labi Siffre and Orzic Tentacles (all of whom appeared at the Waterfront in the space of a week in November 1991). The £1 million project opened in late 1990, amid much publicity and intense criticism from the opposition parties and local residents: these complaints continued into the venue's second year, when it received a further subsidy of £30,000 from the council. Why did the council take these risks? What were the political interests and values which led to this novel policy development?

We obtained two astronomical values, the Earth-Venus distance and Venus diameter, by means of a geometrical treatment of photos taken of Venus transit in June of 2012. Here we presented the static and translational models that were elaborated taking into account the Earth and Venus orbital movements. An additional correction was also added by considering the Earth rotation movement. The results obtained were compared with the values of reference from literature, showing very good concordance.

Abstract:
We report a new method for precise quantification of lung microvascular diameter. Isolated blood-perfused rat lungs (500-g Sprague-Dawley rats) at constant inflation pressure [alveolar pressure (PA)] and stopped blood flow were viewed by microscopy and video. Subpleural venules of the second and third postcapillary generations were microinjected with oil colored with Sudan Black. Vascular pressure (Pvas) was varied in steps, and at each step the horizontal diameter (DH) and the length of the oil-filled segment were determined by microcaliper measurements of the replayed video image. At PA = 5 cmH2O, a decrease in Pvas from 25 to 0 cmH2O decreased DH in the second-generation venules from 55 +/- 2 (SE) to 41 +/- 1 microns (n = 13) and in the third-generation venules from 96 +/- 6 to 73 +/- 6 microns (n = 6). The constant-volume oil-filled segment conformed to the cylinder formula in that decreases in DH correlated linearly with 1/ square root of length, thereby indicating that at all Pvas values venular geometry was constant and probably circular in cross section. The decrease in Pvas to -5 cmH2O did not further decrease DH. At Pvas = 10–25 cmH2O, an increase in PA to 15 cmH2O did not significantly increase DH, although the increase in PA did diminish the slope (compliance) of the DH-Pvas relationship in second- but not third-generation venules. We conclude that 1) lung expansion decreases compliance of juxtacapillary venules, 2) venules retain circular cross sections at Pvas between -5 and 25 cmH2O, and 3) venules are patent at subzero Pvas.

Abstract:
Venous disease is a very common disease that affects millions of people worldwide. While some of the factors that cause the development of varicose veins are well understood, the aetiology of venous ulceration is poorly understood. It has been demonstrated that venous valve failure in the large veins is an important factor leading to the development of varicose veins, however whether similar valves exist in the very small superficial veins of the human leg, and what role these valves may have in venous disease, is unknown. Therefore, the purpose of this study is to: 1. Identify whether venous valves are present in the very small superficial veins of the human leg, and if they are present, 2. Describe the density, size distribution, morphology, and regional distribution of these microvenous valves in �normal� cadaveric legs 3. Compare the �normal� microvenous valves from cadaveric tissue with microvenous valves from pathologic legs with chronic venous disease, to answer the hypothesis that individuals that develop venous ulceration have fewer microvenous valves than the normal population. In order to examine microvenous valves, two main methods have been utilised, E12 sheet plastination and vascular casting. These methods in combination provide valuable insights into the anatomy of microvenous channels, and allow examination and quantification of the venous valves. Using several techniques, this study has shown that microvenous valves are present within the very small veins of the superficial tissue of the human leg. These microvalves have been shown to be most prevalent in the smallest of the veins, down to 18[mu]m in diameter. Approximately 60% of the valves were found to be associated with tributaries. The gaiter region was demonstrated to contain the lowest number and density of microvenous valves, significantly less that the upper or mid calf regions. In addition, the gaiter region was found to have a much lower proportion of microvalves in the most superficial veins, when compared with the other regions examined. Contrary to our hypothesis, the number and density of microvalves in venous diseased legs was not different to that of normal legs. Similarly, the size and regional distributions were also not different. However, the microvalves from the venous diseased legs were significantly stretched and incompetent, allowing retrograde flow from the large veins through to the dermal capillaries. In conclusion, this study has shown that venous valves are present in the smallest of the superficial veins of the human leg, and that their density and distribution is not different between normal and venous diseased individuals. However, the microvalves from the diseased legs were incompetent and allowed retrograde flow. The role that these valves play in normal and pathological circulation is unclear, and warrants further examination.

Abstract:
This chapter explores the range of ideas and activities that engaged Quaker women educators during the eighteenth century, a critical period in the development of Friends’ educational efforts. It analyses key writings of Deborah Bell, Rebecca Jones, and Priscilla Wakefield. These women adopted a variety of approaches to instructing youth, ranging from informal mentorship to formal teaching that stressed a ‘guarded’ (Quaker-only) environment. Bell, Jones, and Wakefield shed light on the leading role that Quaker women played in the education and socialization of young Friends. Their writings highlight the importance of the meetinghouse, the schoolhouse, and the printed word as public venues for women who sought to instil Quaker values in future generations.

Abstract:
This concluding chapter examines the continued presence of NFL Films' traditional practices—and the values they deliver—at a time when the National Football League (NFL) evidences less support for programming that displays these conventions. Despite its decreased importance to the contemporary league, the cultural and aesthetic significance of NFL Films productions exceeds the realm of pro football and even sports media. Despite their increased scarcity on venues like ESPN and NFL Network, NFL Films' traditional aesthetic practices and the values they convey circulate independently of the company's depictions of pro football. It is now virtually impossible to watch TV for very long during the football season without witnessing at least one commercial that evokes NFL Films' conventions. This chapter discusses the legacy of NFL Films, including the establishment of a league-owned media infrastructure upon which the NFL continues to expand and that all other major sports organizations have since emulated, along with the creation of a framework from which contemporary sports television developed its formal practices and enhanced its presence on the medium.

Abstract:
This chapter explores the image Plutarch created of the end of Athenian Democracy. Its aim is to show that Plutarch conceived of this end through the lens of the theatre, and to explore the origins of this portrayal. It makes this argument through close study of the intersection of theatre and politics in Plutarch’s Life of Phocion. Plutarch expresses the political significance of crucial moments by drawing attention to their theatrical dimension. Theatrical venues, self-presentation, staging, speech, and props are used in order to create an emotional impact on an Athenian audience. Since Plutarch understood theatre in (mostly) Platonic terms, this evaluation is negative. He wishes to depict an Athenian society predisposed to strong emotion, ready to welcome an exuberant tyrant with open arms despite its previous democratic values.

Abstract:
The chapter gives an outline of Sondheim’s shows performed in the subsidized theater in Europe and their history up until 2010. Government-funded theaters were once a natural place for experiment, now lack of subsidy prompts the question: are Sondheim’s shows being exploited to be “respectable” crowd pleasers by the up-market venues, or can they retain some of their challenging, conceptual origins? Should they be performed by opera houses at all? (If not there, then where should they be performed?) Is Sondheim’s work a barometer for our theatrical times? In the future, how can theaters retain the real artistic quest of these works by delving more deeply, more challengingly into their conceptual framework? Will the values of commercial theater and financial conservatism dictate how these pieces are produced?

This article discusses Internet research ethics, which promises to become an ever-more robust and significant field within information ethics, on the one hand, and research ethics more broadly, on the other. As new venues emerge for human–human and human–machine interaction, it seems certain that new ethical conundrums will emerge. But the overall history of Internet research ethics includes at least some convergence on key values and rights, while at the same time preserving important local differences with regard to approaches to ethical decision making and implementation of basic rights and principles – even across East–West divides. This trajectory suggests not the certainty of finding resolutions to every ethical problem that comes along, but rather the sense of finding such resolutions in the face of new difficulties, with sufficient frequency and success to encourage further efforts to do so.

Abstract:
The Liverpool Philharmonic Society lies fifth in line among the oldest concert-giving organisations in Europe. This chapter, tapping the Society’s archive, examines the fundamental internal and external hierarchies which governed and shaped the early development of the Society’s orchestra. To what extent were core values dictated by external supply and demand and to what extent by the personal interests of the leading figures in the Society? What conclusions can be reached about the elements of Liverpool’s activities that were independently governed by local demands? Probing the social expectations and financial structures that underpinned the Society’s regulations, committees, income, expenditure, venues, audience, performers, repertoire and programming is revealing. It allows us to contextualize the issues facing those who promoted ‘the Science and Practice of Music’ in this prosperous commercial port. The operational models established in these early years laid the foundation for a Society whose orchestra continues to the present day.

Abstract:
The role of international bodies as the place where international debates on bioethical issues take place is investigated. In theory these international venues are supposed to be neutral in that they do not favor any particular traditions or belief systems. As a neutral venue for debates, these international arenas should recede to the background, so to speak, and let all the voices from among all parties involved in the debate and discussion be heard. However, in practice such a scenario scarcely happens, as these fora and venues are often criticized as being dominated by the West and their claim of universal values. In order for the international venues to be a really just place where all the voices are given due prominence, the roles and arrangements of these international organizations need to be scrutinized.

Abstract:
Libraries, telecenters, and cybercafés offer opportunities for wider public access to information and communication technologies (ICT). This paper presents findings of a global exploratory study on the landscape public access venues in 25 countries around the world. The goal of the project was to better understand the users of public access venues and their needs, this being one of several papers that result from the global study. This paper identifies profiles of the users of the different types of venues with respect to age, income, education and gender. While findings are not new, their value lies in the compelling evidence drawn from 25 countries and across different types of public access venues, which has never been done before. Results highlight the importance of strengthening public access venues in non-urban settings and to strengthen programs that reach out to underserved populations. The authors also point to special challenges faced by libraries and telecenters given the immense growth of cybercafés as public access venues in most of the countries studied.

This chapter discusses the physical spaces of the lofts, exploring how the surrounding environment afforded certain types of performer and listener experience. In contrast to architectural accounts of loft conversions for high-end housing—which often romanticize the industrial history of old factories—musicians' accounts tended to be largely devoid of nostalgia for a bygone era. Instead, descriptions of loft jazz venues generally focused on the creative possibilities enabled by the presence of large, raw spaces. By emphasizing the liberatory potential of blank space, rather than the nostalgic echoes of industrial place, organizers stressed underlying values of reclamation and community-building. The chapter goes on to consider descriptions that referenced markers of domesticity in loft venues, a factor that carried additional resonances in regard to gender politics.

In the era of big data, intelligent sports venues have a practical significance to provide personalized service for users and build up a platform for stadium management. This article proposes a new parallel big data promotion algorithm based on the latest achievements of big data analysis. The proposed algorithm calculates the optimal value by using the observed variables Y, the hidden variable data Z, the joint distribution P (Y, Z | θ) and distribution conditions P (Z | Y | θ). The experimental results show that the proposed algorithm has higher accuracy of big data analysis, and can serve the intelligent sports venues better.

Abstract:
A fundamental ingredient of presenting quality arts and entertainment experiences to contemporary audiences is the imaginative design, management and use of the places in which they happen: the venues. This chapter will continue to explore the changing relationship between audiences, producers and presenters of live arts and entertainment by looking at the design and use of physical spaces. Whether we are talking about a large arena,a formal theatre space, a temporary performing space or a mobile cinema, many of the issues facing producers and managers are similar. This chapter will explore a number of issues affecting the design and use of spaces — large and small, formal and informal — and the current trends in venue design and management for presenting entertainment and hearts. In the course of the chapter, we will consider topics such as the history of venue design and the justifications for different venues and building processes, as well as design issues including inclusivity, sustainability,flexibility and the use of technology. Trends including the move towards intimacy and transparency will be looked at in the context of how these issues relate to key values, such as equality, community, innovation and empowerment of the individual.

Abstract:
This chapter enunciates the social, moral, and hygienic anxieties plaguing popular perceptions of secondhand trade at the end of the nineteenth century and the steps taken to placate such concerns. As firsthand production of everyday goods increased in availability and decreased in cost, more still-viable discarded goods made secondhand economies attractive to a broader range of entrepreneurs. Protestant-run salvage businesses, known as "thrift stores" by the 1920s, used contemporary marketing tools to advertise Christianized, sanitized, and Americanized venues for secondhand products. The links between charity and profit created a new breed of business, which I call “philanthropic capitalism,” and established some of the earliest, still-existing American chain businesses. Meanwhile, style’s role in society shifted without diminishing; it grew in general economic, personal aesthetic, and political expressive value while declining as a clear indication of luxury and exclusivity. From the start, clientele included voluntary secondhand shoppers who used secondhand venues to expand their sartorial options.

The discussion of historical trajectories within subcultural exhibition is grounded in examples from Glasgow ranging from the 1920s to the present. This long-term view of cinephile presence in Scotland’s largest city is contextualized in relation to urban transformation and the music and visual art scenes. The chapter considers institutional support, venues, and intermediality in these forms of non-theatrical programming and screening.

Abstract:
Changes in pH and PCO2 influence the aggregation of blood platelets in response to various agents in vitro. In the present study intravital video-microscopy was used to investigate whether changes in systemic blood gas values influence the thromboembolic reaction in vivo as induced by vessel wall injury.The microtrauma was induced by puncturing the walls of microvessels in the rabbit mesentery (diameter range: 20-40 μm) with glass micropipets (tip diameters: 6-8 μm). The thromboembolic reactions were compared in two groups of anesthetized rabbits. The control group was ventilated to keep the blood gas values within normal ranges (means: pH=7.40, pCO2=32.9 mmHg, pO2=104.7 mmHg). The experimental group breathed spontaneously (mean blood gas values: pH=7.34, pCO2=50.5 mmHg, pO2=48.1 mmHg). The pCO2 and pO2 values were significantly different between both groups.In arterioles and venules of both groups bleeding and thrombus formation started immediately following wall puncture. Bleeding times were short (medians between 1.0 and 2.6 s). Parts of the thrombi started to embolize between 11.4 and 18.2 s following wall puncture (medians). In the control group embolization continued for 101 s in the arterioles and 17 s in the venules; during these periods 6 and 1 emboli were produced, respectively (all median values). In the experimental group the duration of embolization in the arterioles was 143 s in which period 7.5 emboli were produced, values not significantly different from control. In the venules of the experimental group embolization and hence platelet reaction went on uninhibited during the whole observation period of 600 s and 30 emboli were produced. Fluid dynamic factors cannot explain the differences in thromboembolic reaction between the control and experimental venules; vessel diameters and red blood cell velocities were not significantly different between both groups. Therefore, it is likely that the change in thromboembolic reaction in the venules results from the changes in systemic PCO2 and/or pO2. The different reactions in arterioles and venules in response to the altered systemic blood gas values might arise from different reactions in the vessel walls.

Abstract:
The Pulsed Neutron Source (PNS) experiment on the Fast-thermal Coupled sub-critical core VENUS-1# has been performed in CIAE with 14MeV accelerator neutron source. The preliminary experimental data indicated spatial dependence of prompt neutron attenuation constant α, which is conflict to traditional theories. To re-evaluate the experiment and probe possible special features of the Fast-thermal Coupled core, a Monte-Carlo simulation of PNS experiment has been performed in this paper. Considering Contamination of harmonics mode of prompt neutrons, a data-processing technique, e.g. harmonics filtering, is used to obtain the fundamental mode decay. The simulated results indicate that, the influence of harmonics and external source are mainly in the time region 0∼500μs after pulsed neutron injection; by harmonics filtering, spatially independent α values are obtained and verified. By the method above, the experimental data are re-processed, however, the problem of the spatially dependence of α is not improved at all, the α value indicated by detector R is still quite different from others’. The works performed in this paper suggest that, some future PNS experiments should be deployed to confirm the experimental phenomenon.

Abstract:
The Joint Interagency Field Experimentation (JIFX) event, organized by the Naval Postgraduate School (NPS), is conducted 3-4 times a year at various locations. The four day event can be characterized as an informing system specifically designed to facilitate structured and unstructured communications between a variety of parties—e.g., software developers, inventors, military and civilian users of various technologies, academics, and agencies responsible for identifying and procuring technology solutions—that frequently are constrained in their informing activities in more restrictive venues. Over the course of the event, participants may observe technology demonstrations, obtain feedback from potential users, acquire new ideas about their technologies might be employed and, perhaps most significantly, engage in ad hoc collaborations with other participants. The present paper describes an exploratory case research study that was conducted over a one year period and involved both direct observation of the event and follow-up interviews with 49 past participants in the event. The goal of the research was to assess the nature of participant-impact resulting from attending JIFX, and considering the consistency of the findings with the predictions of various theoretical frameworks used in informing science. The results suggest that participants perceived that the event provided significant value from three principal sources: discovery, interaction with potential clients (users) of the technologies involved, and networking with other participants. These findings were largely consistent with what could be expected from informing under conditions of high complexity: because value generally derives from combinations of attributes rather than from the sum of individual attributes, we would expect that overall value from informing activities will be perceived even though estimates of the incremental value of that informing cannot be made.

Abstract:
An international programme called REBUS for the investigation of the burn-up credit has been initiated by the Belgian Nuclear Research Centre SCK-CEN and Belgonucle´aire with the support of EdF and IRSN from France and VGB, representing German nuclear utilities and NUPEC, representing the Japanese industry. Recently also ORNL from the U.S. joined the programme. The programme aims to establish a neutronic benchmark for reactor physics codes in order to qualify the codes for calculations of the burn-up credit. The benchmark exercise investigates the following fuel types with associated burn-up: reference fresh 3.3% enriched UO2 fuel, fresh commercial PWR UO2 fuel and irradiated commercial PWR UO2 fuel (54 GWd/tM), fresh PWR MOX fuel and irradiated PWR MOX fuel (20 GWd/tM). The experiments on the three configurations with fresh fuel have been completed. The experiments show a good agreement between calculation and experiments for the different measured parameters: critical water level, reactivity effect of the water level and fission-rate and flux distributions. In 2003 the irradiated BR3 MOX fuel bundle was loaded into the VENUS reactor and the associated experimental programme was carried out. The reactivity measurements in this configuration with irradiated fuel show a good agreement between experimental and preliminary calculated values.
