Post-focus expansion of ion beams for low fluence and large area MeV ion irradiation: Scaling from the single-event to the system level in human brain tissue and electronics devices
No full textIrradiation with ~ 3 MeV proton fluences of 10⁶ - 10⁹ protons cm⁻² have been applied to study the effects on human brain tissue corresponding to single-cell irradiation doses and doses received by electronic components in low-Earth orbit. The low fluence irradiations were carried out using a proton microbeam with the post-focus expansion of the beam; a method developed by the group of Breese [1]. It was found from electrophysiological measurements that the mean neuronal frequency of human brain tissue decreased to zero as the dose increased to 0 to 1050 Gy. Enhancement-mode MOSFET transistors exhibited a 10% reduction in threshold voltage for 2.7 MeV proton doses of 10Gy while a NPN bipolar transistor required ~800 Gy to reduce the h��ₑ by 10% which is consistent the expected values
Toward an Understanding of How Post-Deployment User-Developer Interactions Influence System Utilization
No full textAlthough initial adoption of an information system has been shown to influence system success, further value can be obtained when end-users move beyond adoption, utilizing more features of the system and integrating it into their work routines. Organizations can increase the post-deployment utilization of their systems by emphasizing continued interaction between developers and end-users. In this study, we develop a research model investigating the influence of shared understanding, faithfulness of appropriation, and consensus on spirit on post-deployment system utilization. Using a sample from a healthcare organization, we show that increased end-user post-deployment interaction with developers supports a shared understanding between the two groups, which ultimately impacts both the routinization and infusion of a system. This study provides a contribution by demonstrating the impact of developer/user interaction in the post-implementation phase of systems development
Plagiarism and Authorship: A Review and Retrospective of the CCCC Intellectual Property Annual
No full textFood For Thought
No full textHealthy eating is essential to avoid many health problems, but identifying health-promoting foods and behaviors is difficult for most individuals. Fooducate is a diet tracking app that comes with a variety of tools, features and support mechanisms that claim to simplify the task of eating healthy. Based on our analysis of the user reviews, we identified five benefits that Fooducate users have reported experiencing in relation to achieving good health: improved food choices, increased awareness, weight loss personalized care and “ever-present” human support. Fooducate can align itself more closely with users’ goal of achieving healthy lifestyle by expanding its database, making its interfaces flexible, improving its ability to provide personalized care and revising its ideological choices
Ilya Repin in Paris: Mediating French Modernism
No full textThis article explores the development of a singular painting by Russia’s most famous realist painter, Il’ia Repin. First exhibited under the title Un café du boulevard, the work was conceived during Repin’s stay in Paris from 1873-75. Repin himself described the work as “the main types of Paris in their most typical place,” but what he produced proves a departure for the young artist not only in terms of its Parisian subject matter. Careful analysis of Repin’s letters and the work itself show him searching for a stylistic language that had universal translatability in this moment, one that he importantly associated with the French artist Édouard Manet. Understanding how Repin came to center his painting on cocottes and flâneurs, the foremost heroes of western European urbanity, allows for a new understanding of transnational connections in late nineteenth-century art, one in which Russian artists mediated French modernism as it was developing

Men\u27s Time: Pavel Fedotov and the Pressures of Mid-Nineteenth-Century Masculinity
No full textFor seven weeks in the spring of 1835, the Russian painter Pavel Fedotov kept a journal. He was, in these months, still an officer serving in the Finland Regiment of the Imperial Guards in St. Petersburg, but he was ultimately to become known as Russia’s most celebrated early realist painter. The journal preserves in unusual depth of detail the monotony and perpetual sameness which characterized life for the nineteen-year old officer as he grew his painterly skill. Examining it, along with a small cluster of the artist’s paintings and drawings, shows that the repetitiousness found in the journal also characterized Fedotov’s painting practice. Time and again, the artist added details to his works that emphasized the durational aspect of the single depicted moment. Tropes of visual and narrative extensiveness, these elements parallel what the intellectual Petr Chaadaev called in these same years “the stifling embraces of time.” Both were concerned to emphasize a new restless futility they perceived among a generation of Russian men, one that can be linked to a problem in these men’s relationship to time itself. Utilizing excerpts from Fedotov’s previously untranslated journals and letters, as well as the literary and philosophical works of his contemporaries, this article investigates how temporality was experienced in newly problematic ways and develops a new interpretation of the social organization of time along gendered lines
Investigations of minor elements in early aluminium artefacts
Get PDFStudy of the minor and trace element contents in the composition of early aluminium is interesting from a cultural history perspective because it can provide information on the evolution of aluminium smelting practice. A range of aluminium artefacts from the Swiss National Museum and the Lausanne Historical Museum, Switzerland, have been characterised with regard to their minor and trace element composition. This was performed using external beam Particle Induced X-ray Emission (PIXE) with 1 MeV protons and a portable X-ray fluorescence system. The concentration of Mn and Pb was significantly higher for artefacts produced by the amalgam process which confirms studies reported by others
