  1. Writing your curriculum vitae. (United States)

    McKenzie, S


    Your curriculum vitae (CV) is your gateway to shortlisting. A good CV takes a long time to prepare. It should not only record your training but, more importantly, should reflect your 'physicianly' qualities, management skills and knowledge of health-care systems.

  2. Visulaizing the Curriculum Vitae

    DEFF Research Database (Denmark)

    Wildgaard, Lorna Elizabeth; Lund, Haakon

    In research assessment and job applications, researchers are required to submit their curriculum vitae (CV) and publication lists as part of the evaluation process. Typically, the CV and publication list are presented as two seperate documents, listing chronologically academic activities...... and publications. Relational and contextual information are perhaps added in a short narrative, but primarily there is a dislocation between the two documents. Increasingly, evaluations are managing large volumes of data and it is important for the evaluand to create insight from their existing data. In this case......, the relationships between publications and academic activites matter more than the individual activity. In order to leverage relationships in CV and publication data, we explore the usefulness of OrientDB, a multimodel noSQL database with a graph database engine, that claims to be simple and effecient to use...

  3. The digital curriculum vitae. (United States)

    Galdino, Greg M; Gotway, Michael


    The curriculum vitae (CV) has been the traditional method for radiologists to illustrate their accomplishments in the field of medicine. Despite its presence in medicine as a standard, widely accepted means to describe one's professional career and its use for decades as an accomplice to most applications and interviews, there is relatively little written in the medical literature regarding the CV. Misrepresentation on medical students', residents', and fellows' applications has been reported. Using digital technology, CVs have the potential to be much more than printed words on paper and offers a solution to misrepresentation. Digital CVs may incorporate full-length articles, graphics, presentations, clinical images, and video. Common formats for digital CVs include CD-ROMs or DVD-ROMs containing articles (in Adobe Portable Document Format) and presentations (in Microsoft PowerPoint format) accompanying printed CVs, word processing documents with hyperlinks to articles and presentations either locally (on CD-ROMs or DVD-ROMs) or remotely (via the Internet), or hypertext markup language documents. Digital CVs afford the ability to provide more information that is readily accessible to those receiving and reviewing them. Articles, presentations, videos, images, and Internet links can be illustrated using standard file formats commonly available to all radiologists. They can be easily updated and distributed on an inexpensive media, such as a CD-ROM or DVD-ROM. With the availability of electronic articles, presentations, and information via the Internet, traditional paper CVs may soon be superseded by their electronic successors.

  7. [Curriculum vitae organization: the Lattes software platform]. (United States)

    Amorin, Cristiane V


    Curriculum vitae is a Latin expression meaning "career" or "life course". That means the data set concerning name, age, marital status, situation, studies, diplomas, published works and other activities of a student, an applicant for a position, for an exam or for a public office, and others. In short, it is the document that provides an outlook of the person as an individual; that is why this document must be carefully prepared as to precise and true contents, as to presentation and as to writing.

  15. Creating Curriculum Vitae for Understanding People on the Web (United States)

    Ueda, Hiroshi; Murakami, Harumi; Tatsumi, Shoji

    When users find information about people from the results of Web people searches, they often need to browse many obtained Web pages and check much unnecessary information. This task is time-consuming and complicates the understanding of the designated people. We investigate a method that integrates the useful information obtained from Web pages and displays them to understand people. We focus on curriculum vitae, which are widely used for understanding people. We propose a method that extracts event sentences from Web pages and displays them like a curriculum vita. The event sentence includes both time and events related to a person. Our method is based on the following: (1) extracting event sentences using heuristics and filtering them, (2) judging whether event sentences are related to a designated person by mainly using the patterns of HTML tags, (3) classifying these sentences to categories by SVM, and (4) clustering event sentences including both identical times and events. Experimental results revealed the usefulness of our proposed method.

  19. Preparing a successful, role-specific curriculum vitae. (United States)

    Price, Bob


    An internet search reveals just how many articles there are on preparing a curriculum vitae (CV). The preparation of a CV should not be regarded as a 'one-off' event, to be updated periodically. A successful CV requires thoughtful preparation to ensure it is directed towards a specific post and should consider two important perspectives. First, an understanding of what is required of the practitioner in the nursing post (demand), and second, what the nurse can offer in terms of his or her skills, experience, qualities and qualifications (supply). The demands of the post will also include meeting professional standards, such as those that have emerged following consideration of the Report of the Mid Staffordshire NHS Foundation Trust Public Inquiry (Francis 2013). This article explores how to prepare a successful CV for a specific role, using a demand and supply perspective--where a nurse seeks to match the specific requirements of the post by summarising what he or she has to offer.

  20. Research: A Pathway Towards a Good Curriculum Vitae

    Directory of Open Access Journals (Sweden)

    Muhammad T. Shakoor


    Full Text Available Nowadays there is a lashing trend of doing fellowships. Residency and fellowship positions have become very competitive. From my experience, I found that the majority of candidates who aspire to apply for residency or fellowship positions don’t have any significant research backgrounds. Being a medical student myself, I should not blame any other student for this deficiency, as most of the medical schools don’t provide basic atmosphere, guidance and infrastructure for undergraduate research activities. By the time students graduate and apply for a residency spot or fellowship position after residency, they have no research credentials with them other than their degree requirements and a few certificates for extracurricular activities. One should realize that these accomplishments merely provide a skeleton for your Curriculum vitae (CV in order to add depth to your CV you have to be able to include research experiences (that you have acquired during your undergraduate degree, as well as good recommendation letters and advanced clinical experience.1 Research work in your CV will help set you apart. When you go for a job interview, having a strong research background and independent work gives you something to talk about that the interviewer will be interested in. As a student, any efforts in the field of research are highly appreciated. Above all, research training will make you a better-equipped physician with a sharper mind and stronger critical thinking skills.

  1. Ten steps to writing curriculum vitae covering letters. (United States)

  2. Importance of components of the curriculum vitae in determining appointment to senior registrar posts. (United States)

    Conn, D A; Asbury, A J


    To evaluate the opinions of regional education advisers, academics and other consultants about features of the curriculum vitae, we undertook a small attitude survey. The response rate was 73%, which provided data from a total of 78 influential anaesthetists. The respondents' attitude to each feature of the curriculum vitae was reported using a linear visual analogue scale. The three groups had similar attitude scores to most features, but not to research time, training time, higher degrees and abstracts of papers presented to the Anaesthetic Research Society. Publications in the main anaesthesia journals, time in other major medical specialties, research and the possession of a higher degree were scored highly by all respondents. Papers in non-peer-reviewed journals, letters, unsubmitted papers, and time in training for general practice attracted lower scores. The free text comments of many respondents indicated a considerable disillusionment about the whole appointments process.

  3. Evaluating faculty development outcomes by using curriculum vitae analysis. (United States)

    Morzinski, J A; Schubot, D B


    Many faculty development (FD) programs depend on external private and public sponsors that routinely require systematic studies on FD outcomes. The results of evaluation studies can influence whether or not programs continue to be funded. To better evaluate program outcomes on academic productivity, this paper presents and illustrates an evaluation method that uses the curricula vitae (CVs) of FD program graduates. The evaluation method is implemented by first preparing a record-review template of coding categories that is applied to FD graduates' updated CVs. Next, semi-structured interviews are held with subjects to resolve uncertain CV codes. Finally, coded data are entered into standardized forms and analyzed to yield descriptive findings. The method was piloted with two groups of FD graduates (n = 17) to determine its utility and limitations. Results show excellent inter-rater reliability (Cohen's Kappa = .79). There was an overall increase in productivity, measured by the CV, during and after the FD program. CV analysis can be a useful method for assessing FD program outcomes. Several limitations of the method, such as incomplete CVs and self-report bias, must be considered.

  5. Tips for a physician in getting the right job, part II: the curriculum vitae, cover letter, and personal statement. (United States)

    Harolds, Jay A


    It is very important that a job seeker prepares an excellent curriculum vitae (CV) and cover letter. Often a personal statement is also needed. If these are not done well, often an interview is not granted. There are different formats and headings for the CV, depending on the type of job sought and the institution the job is located in. There are also some differences in how this is done between different countries. However, there are also many common elements of a proper CV.

  6. Curriculum vitae of the LOTOS–EUROS (v2.0 chemistry transport model

    Directory of Open Access Journals (Sweden)

    A. M. M. Manders


    Full Text Available The development and application of chemistry transport models has a long tradition. Within the Netherlands the LOTOS–EUROS model has been developed by a consortium of institutes, after combining its independently developed predecessors in 2005. Recently, version 2.0 of the model was released as an open-source version. This paper presents the curriculum vitae of the model system, describing the model's history, model philosophy, basic features and a validation with EMEP stations for the new benchmark year 2012, and presents cases with the model's most recent and key developments. By setting the model developments in context and providing an outlook for directions for further development, the paper goes beyond the common model description.With an origin in ozone and sulfur modelling for the models LOTOS and EUROS, the application areas were gradually extended with persistent organic pollutants, reactive nitrogen, and primary and secondary particulate matter. After the combination of the models to LOTOS–EUROS in 2005, the model was further developed to include new source parametrizations (e.g. road resuspension, desert dust, wildfires, applied for operational smog forecasts in the Netherlands and Europe, and has been used for emission scenarios, source apportionment, and long-term hindcast and climate change scenarios. LOTOS–EUROS has been a front-runner in data assimilation of ground-based and satellite observations and has participated in many model intercomparison studies. The model is no longer confined to applications over Europe but is also applied to other regions of the world, e.g. China. The increasing interaction with emission experts has also contributed to the improvement of the model's performance. The philosophy for model development has always been to use knowledge that is state of the art and proven, to keep a good balance in the level of detail of process description and accuracy of input and output, and to keep a good record

  7. [Curriculum vitae aortae]. (United States)

    Solberg, S


    The Greek word aorta means lifter. The vessel was so termed because Aristotle, who first described it, assumed that the heart was lifted by/hanging in aorta. Leonardo da Vinci described the detailed anatomy of aorta. During the 17th century our present understanding of the aorta and the circulation of blood took form due to the descriptions given by William Harvey. The first known operation for abdominal aortic aneurysm was performed in London in 1817 by Sir Astley Cooper who ligated the infrarenal aorta above the aneurysm. Puncture with needles and application of electricity were later tried in order to induce thromboses in the aneurysm. In 1948 Albert Einstein was operated with wrapping of his abdominal aneurysm with cellophane. In 1955 he suffered rupture and died after having refused operation. In 1951 the first successful operation for abdominal aortic aneurysm was performed in Paris by Charles Dubost. With slight modifications, the same operative technique is used today.

    Full Text Available Situando-se dentro da perspectiva sociointeracionista, este trabalho visa discutir dados recortados de uma pesquisa desenvolvida com o gênero curriculum vitae (CV, em inglês, por meio de uma sequência didática elaborada especificamente para tal fim e aplicada a acadêmicas do 4º ano do curso de Letras Português/Inglês, da Universidade Estadual de Maringá, em 2009. Como aporte teórico, utilizamos a concepção bakhtiniana de gêneros discursivos, a proposta de sequência didática e a discussão sobre lista de controle para correção da produção escrita dos alunos. Os resultados apontam algumas lacunas observadas no desenvolvimento do trabalho e mostram que, dentre as capacidades de linguagem trabalhadas, as capacidades discursiva e linguístico-discursiva são mais desenvolvidas do que a capacidade de ação na produção final das acadêmicas.Grounded on the socio-interactionist perspective, this work aims at discussing data of a research carried out by means of a didactic sequence of the genre Curriculum vitae (CV, in English. This didactic sequence was developed with 4th year students of the Language Arts Undergraduate Course - Portuguese/ English, at the State University of Maringá. Theoretical assumptions are drawn from the bakhtinian notion of discursive genres, from the concept of didactic sequence and from the discussion about control lists. The data demonstrate some gaps observed during the development of the sequence. They also show that, among the language capacities taught in the sequence, the discursive and linguistic-discursive ones are more developed than the action capacity in the students' final production.

  17. PHP-HT (VitaResc Biotech). (United States)

    Baldwin, A; Wiley, E


    VitaResc (formerly Apex) is developing PHP-HT, pyridoxalated hemoglobin polyoxyethylene conjugate, for the potential treatment of nitric oxide-induced shock (characterized by hypotension), associated with various etiologies, initially in septic shock. A phase I safety study and an initial phase I/II patient trial for NO-induced shock have been completed, and VitaResc has enrolled patients in three of five planned cohorts in a continuation of these trials to include a protocol of continuous infusion and dose escalation [330680,349187,390918]. The results from the dose escalation trials are expected to provide the basis for a randomized, controlled phase II/III pivotal trial of PHP-HT [390918]. VitaResc has licensed PHP-HT exclusively from Ajinomoto for all indications, worldwide, except Japan [275263]. Ajinomoto originally developed the human derived and chemically modified hemoglobin preparation as a blood substitute, but no development has been reported by the company since 1997 [275277,303577]. The other potential indications of PHP-HT include shock associated with burns, pancreatitis, hemodialysis and cytokine therapies [275277]. VitaResc expects the annual market potential of PHP-HT to exceed 1 billion dollars [330680].

  18. Scientific recognition in numbers: analysis of the profile of a vanguard from Lattes curricula vitae

    Directory of Open Access Journals (Sweden)

    Miguel Ângelo Montagner


    Full Text Available The objective was to analyze the possibilities and limitations of quantitative study on an institution and its professionals, taking into account the Lattes curriculum vitae platform. Through exploring this material, we sought to delineate the profile of professors of the UNICAMP School of Medical Sciences and to characterize their scientific production, main activities and academic profile. The methodology used was quantitative. Based on descriptive statistics, we outlined and analyzed the main characteristics these professors presented in their curricula vitae, which are stored in the database of the Lattes Platform. Next, using qualitative analysis based on the theories of Pierre Bourdieu, we emphasized the difficulties in achieving good descriptions of researchers' social and scientific paths based on the Lattes Platform. Thus, the Lattes system consists of a repository of finished scientific actions, comprising a linear, non-historical succession within official science.

  19. A curriculum vitae of teeth: evolution, generation, regeneration. (United States)

    Koussoulakou, Despina S; Margaritis, Lukas H; Koussoulakos, Stauros L


    The ancestor of recent vertebrate teeth was a tooth-like structure on the outer body surface of jawless fishes. Over the course of 500,000,000 years of evolution, many of those structures migrated into the mouth cavity. In addition, the total number of teeth per dentition generally decreased and teeth morphological complexity increased. Teeth form mainly on the jaws within the mouth cavity through mutual, delicate interactions between dental epithelium and oral ectomesenchyme. These interactions involve spatially restricted expression of several, teeth-related genes and the secretion of various transcription and signaling factors. Congenital disturbances in tooth formation, acquired dental diseases and odontogenic tumors affect millions of people and rank human oral pathology as the second most frequent clinical problem. On the basis of substantial experimental evidence and advances in bioengineering, many scientists strongly believe that a deep knowledge of the evolutionary relationships and the cellular and molecular mechanisms regulating the morphogenesis of a given tooth in its natural position, in vivo, will be useful in the near future to prevent and treat teeth pathologies and malformations and for in vitro and in vivo teeth tissue regeneration.

  20. Dispositivi formativi e forme di vita

    Directory of Open Access Journals (Sweden)

    Francesco Cappa


    Full Text Available Il dibattito pedagogico che ha caratterizzato gli ultimi anni ha spesso insistito sull’importanza del nesso tra sviluppo tecnologico e modelli formativi. Questa relazione, però, troppo spesso non valorizza i modi in cui l’esperienza educativa e formativa dovrebbe essere sempre più accuratamente pensata, progettata e predisposta se vista dalla prospettiva delle buone pratiche tecnologiche. Tale valorizzazione dell’istanza formativa deve prendere avvio da una riflessione critica e approfondita sui modelli impliciti ed espliciti che caratterizzano le pratiche educative e formative, valorizzando l’uso e l’interpretazione che i soggetti rendono attuali.Per consentire tale riflessione è necessario pensare un dispositivo pedagogico che non perda di vista la complessità delle dimensioni che agiscono nell’accadere educativo, capace di creare nuovi percorsi di sperimentazione delle conoscenze e nuove ipotesi di formazione di sé e degli altri. La formazione interpretata alla luce dei dispositivi pedagogici può offrire un valido strumento teorico e pratico per immaginare, progettare e valutare gli effetti che ogni azione formativa produce legati alla trasformazione dei saperi, alla vita delle forme e alle forme di vita contemporanee.

  2. Vitalmente morituri: una riflessione tra la vita e la morte

    Directory of Open Access Journals (Sweden)

    Emilio Gardini


    Full Text Available La morte è un fenomeno “regimentato” dall'imprevisto che si scontra con il desiderio razionale del prosieguo; non accetta né governo né cura, e l'uomo vuole neutralizzarne la carica destabilizzante. In molti casi però il confine tra la vita e la morte è veramente sottile, tanto sottile che non è più possibile tenere la morte ai margini della nostra esistenza, essa ne diventa parte. Rientra tra le pratiche quotidiane che è necessario render parte “almeno” delle nostre riflessioni, andando oltre quel confine labile che la separa dalle nostre attività in vita. È in questo modo che qualcuno “agisce” la morte come si fa con la vita, che non significa solo affrontarla, ma riconoscerla come parte esistente della vita stessa, scegliendo di ridurla a fatto “vitale”. Il nostro mondo dipende da come ci rapportiamo ai fatti, e tra questi anche alla morte, il nostro “essere umani” sta in ciò che rientra nel nostro essere in vita e in morte. Vitalmente morituri, quindi, capaci di vivere e morire, di “agire” la vita e anche la morte. Ma in verità si tratta di riflessioni, dei tentativi che mettono insieme astrazione e azione per comprendere alcune scelte e ridurle a categorie conoscibili così come l’interpretazione sociologica permette di fare, tuttavia, direi, che abbiamo ancora molta paura della morte.

  3. Selecting VITA classical shades with the VITA 3D-master shade guide. (United States)

    Zenthöfer, Andreas; Wiesberg, Stefan; Hildenbrandt, Achim; Reinelt, Gerhard; Rammelsberg, Peter; Hassel, Alexander J


    Although the VITA 3D-Master (3D) shade guide offers improved shade-matching performance, many dental materials are only available in VITA Classical (VC) shades. This study aimed to clarify whether it is possible to convert 3D shades determined by observers into VC shades (indirect method) without adding a clinically significant error in comparison with direct shade determination using the VC shade guide. Forty ceramic specimens were fabricated. L*a*b* values were recorded using a spectroradiometer. Sixty participants (35 dentists, 15 technicians, and 10 students) were recruited and asked to determine the shades of specimens using the VC and 3D shade guides under standardized conditions. Conversion tables were constructed by allocating the closest VC shade tab to every matched 3D shade and by use of an optimization algorithm (indirect methods). Differences between ΔE values for VC matches and for the indirect methods were evaluated using t tests. A mean ΔE (SD) of 4.34 (2.00) for VC and 4.22 (2.21) for 3D was observed (P = .040). Compared with direct shade matching using VC, the indirect method with the optimized tables resulted in a mean ΔE of 4.32 (1.96), which was not significantly different (P = .586). Within the limitations of this study, the conversion tables were suitable for the determination of tooth color using the 3D shade guide followed by conversion into VC shades without adding a clinically significant error.

    Today there is a growing demand for safe and efficient antimicrobial dressings for infected wound treatment. The antimicrobial sorption material for VitaVallis dressings was produced by one-stage oxidation of aluminum nanopowder in water in the presence of fibrous acetylcellulose matrix. Scanning electron microscopy revealed that the material is made up of fibers of diameter 1.5–3.0 µm with adhered agglomerated alumina nanosheets. An antimicrobial study revealed a high inhibitory effect of VitaVallis against the growth of gram-negative (E.coli, P. aeruginosa) and gram-positive (S. aureus) strains. The antimicrobial activity of the dressing against microbial pathogens on the wound surface was demonstrated in in vivo experiments on male rats. The dressing was also tested on volunteer patients. The testing showed reduction of the wound healing period, accelerated cleaning of the infected wound and enhanced tissue regeneration in the wound. The results demonstrate that the VitaVallis dressing can be used for the treatment of deep infected wounds.

    Full Text Available Questo saggio si concentra su due romanzi storici che hanno per argomento la Seconda guerra mon- diale e lo sterminio degli ebrei d’Europa: Vita e destino di Vasilij Grossman (1980 e Le Benevole di Jonathan Littell (2006. La scelta è determinata sia dal rapporto esistente tra i due romanzi, sia dalla convinzione che essi rappresentino, per forma e contenuti, due diversi paradigmi attraverso i quali l’immaginario collettivo ha costruito la narrazione dell’evento guerra. Inoltre si tratta di opere che hanno, in tempi diversi, creato un caso letterario: Le Benevole ha sollevato molti problemi orientando il dibattito su temi etici piuttosto che estetici; Vita e destino ha subito la censura in Unione Sovietica. In questa sede si è scelto di analizzare i romanzi da una prospettiva strettamente letteraria, attraverso due argomenti: la legittimità della costruzione finzionale in rapporto al punto di vista dell’autore (testimone dei fatti narrati nel caso di Grossman, post-testimone nel caso di Littell e l’analisi degli elementi romanzeschi di tradizione ottocentesca e modernista. This paper focuses on two novels narrating the Second World War and the extermination of the Jews of Europe: Life and Fate, by Vasily Grossman (1980, and The Kindly Ones by Jonathan Littell (2006. These books have been chosen because they are closely related to each other and because they embody two different paradigms through which the Second World War has been represented. Moreover both Life and Fate and The Kindly Ones have been literary events: the first was censored in the Soviet Union, the second gave rise to a wide-ranging debate on ethical and aesthetical problems. The following paper analyzes these novels from a strictly literary perspective, focusing on two issues: the legitimacy of fiction (Grossman narrates the war from the standpoint of a witness, Littell, born in 1967, is in the position of the historian and the relationship of these texts with the

Basado en la Vita Christi de Ludolfo de Sajonia, el Cartujano, puede en realidad interpretarse como una Vita Mariae, pues en él se presta atención particular al papel de la Virgen en la vida de Cristo. Este artículo analiza los paralelos entre esta obra y las prosas mitológicas de Joan Roís de Corella. En los dos puede verse un interés en temas amorosos y en la descripción de los afectos y el mundo interior emocional de los personajes. The Vita Christi by Sor Isabel de Villena is a paramount text written in medieval Iberia. Based on the Vita Christi by Ludolf of Saxony (the Carthusian, the work can be interpreted as a Vita Mariae for it pays particular attention to the role of the Virgin in Christ’s life. This article explores the parallels between Sor Isabel de Villena’s hagiographical text and the mythological prose works by Joan Roís de Corella. Both share an interest on love and on describing affects and the emotional inner world of the characters.

  17. Curriculum vitae of intestinal intraepithelial T cells: their developmental and behavioral characteristics. (United States)

    Ishikawa, Hiromichi; Naito, Tomoaki; Iwanaga, Toshihiko; Takahashi-Iwanaga, Hiromi; Suematsu, Makoto; Hibi, Toshifumi; Nanno, Masanobu


    The alimentary tract has an epithelial layer, consisting mainly of intestinal epithelial cells (IECs), that is exposed to the exterior world through the intestinal lumen. The IEC layer contains many intestinal intraepithelial T cells (IELs), and the total number of IELs constitutes the largest population in the peripheral T-cell pool. Virtually all gammadelta-IELs and many alphabeta-IELs in the mouse small intestine are known to express CD8 alpha alpha homodimers. A wide range of evidence that supports extrathymic development of these CD8 alpha alpha(+) IELs has been collected. In addition, while several studies identified cells with precursor T-cell phenotypes within the gut epithelium, how these precursors, which are dispersed along the length of the intestine, develop into gammadelta-IELs and/or alphabeta-IELs has not been clarified. The identification of lymphoid cell aggregations named 'cryptopatches' (CPs) in the intestinal crypt lamina propria of mice as sites rich in T-cell precursors in 1996 by our research group, however, provided evidence for a central site, whereby precursor IELs could give rise to T-cell receptor-bearing IELs. In this review, we discuss the development of IELs in the intestinal mucosa and examine the possibility that CPs serve as a production site of extrathymic IELs.

    Singer, Silke S; Männel, Daniela N; Hehlgans, Thomas; Brosius, Jürgen; Schmitz, Jürgen


    Exonization of Alu retroposons awakens public opinion, particularly when causing genetic diseases. However, often neglected, alternative "Alu-exons" also carry the potential to greatly enhance genetic diversity by increasing the transcriptome of primates chiefly via alternative splicing.Here, we report a 5' exon generated from one of the two alternative transcripts in human tumor necrosis factor receptor gene type 2 (p75TNFR) that contains an ancient Alu-SINE, which provides an alternative N-terminal protein-coding domain. We follow the primate evolution over the past 63 million years to reconstruct the key events that gave rise to a novel receptor isoform. The Alu integration and start codon formation occurred between 58 and 40 million years ago (MYA) in the common ancestor of anthropoid primates. Yet a functional gene product could not be generated until a novel splice site and an open reading frame were introduced between 40 and 25 MYA on the catarrhine lineage (Old World monkeys including apes).

  20. Existential dynamic therapy ("VITA") for treatment-resistant depression with cluster C disorder: matched comparison to treatment as usual. (United States)

    Stålsett, Gry; Gude, Tore; Rønnestad, M Helge; Monsen, Jon T


    Existential suffering may contribute to treatment-resistant depression. The "VITA" treatment model was designed for such patients with long-standing depression accompanied by existential and/or religious concerns. This naturalistic effectiveness study compared the VITA model (n = 50) with a "treatment as usual" comparison group (TAU; n = 50) of patients with treatment-resistant depression and cluster c comorbidity. The TAU patients were matched on several characteristics with the VITA patients. The VITA model included existential, dynamic, narrative and affect-focused components. The VITA group had significantly greater improvement on symptom distress and relational problems during treatment and from pre-treatment to 1-year follow-up. Patients in the VITA, at follow-up, were more likely to be employed and less likely be using psychotropic medications.

    Marco Dorigatti


    Full Text Available Inteso quale omaggio a Emilio Bigi, sia pure indiretto, lo studio prende spunto da un’intervista, tuttora inedita, rilasciata nel 1984 dallo scrittore argentino Jorge Luis Borges, in cui aveva citato, credendoli ariosteschi, dei versi che per lui, giunto in età ormai avanzata, erano diventati, più che un motto, una metafora di vita. Poco importa che, come verrà chiarito vagliando la loro storia e le relative fonti, quei versi, facenti capo alla misteriosa figura di un personaggio saraceno, Alibante di Toledo, in realtà appartenessero all’officina poetica di Francesco Berni: essi vengono ciò nondimeno assunti quale filo conduttore per un percorso esplorativo all’interno dell’Orlando furioso che ne vaglia la valenza per così dire “ariostesca”, giusta la reminiscenza borgesiana. Approdata infine a Cervantes, la discussione si conclude facendo ritorno a Borges e misurando l’impatto che quei medesimi versi hanno avuto sulla sua propria opera poetica.Intended as a heartfelt tribute to Emilio Bigi, albeit an indirect one, this essay draws on an interview, still unpublished, given by Argentine writer Jorge Luis Borges in 1984, in which he quoted a couple of lines of poetry which he firmly believed to be by Ariosto, and which for him, by then an old man, had become, more than a motto, a metaphor of life. It does not really matter that, as will become apparent retracing their history as well as their sources, these lines, centring on the mysterious figure of a Saracen character called Alibante of Toledo, actually belonged to Francesco Berni: they are here assumed as the main motif to be explored within Orlando furioso, in order to ascertain to what extent their nature may be regarded to be Ariostan, just as Borges thought. Having finally reached Cervantes, the discussion concludes by returning once more to Borges and considering the impact that these lines, which had remained engrained in his memory throughout his life, had on his own

This fact has not been mentioned yet in any of the literature studies devoted to Glinka’s works. It is believed that The Vita of Lazar of Murom was created during the period between the late 14th and early 15th century. At the end of the 18th century this manuscript’s copy belonged to a high rank Petrozavodsk offi cial I. A. Pykhtin. In 1805, he consigned his copy of The Vita of Lazar of Murom to a well-known Petrozavodsk historian T. V. Balandin, who made another copy of it. Soon T.V. Balandin transferred his copy to a famous Orthodox church historian Evgenii (Bolkhovotinov, who in turn published this copy in 1813 in the 5th volume of his work The History of Russian Hierarchy. In 1826–1830, poet Fyodor Glinka was sent to exile in Petrozavodsk for having participated in the Decembrist movement. He met T. V. Balandin, read the text of The Vita of Lazar of Murom and included a story about a monk who had moved from Greece to Russia into his poem Karelia, published in 1830. Besides, the name of Saint Lazar is mentioned in the main text of the poem and twice in its footnotes. Glinka had a great intuitive feel for a language and noticed correlation between style and authenticity of the legend about Lazar’s life. So, The Vita of Lazar of Murom became one of the sources which inspired Fyodor Glinka to create his poem Karelia and to certain extent determined its content.

  10. HADRIAN THE TRAVELER: Motifs and Expressions of Roman Imperial Power in the Vita Hadriani

    Directory of Open Access Journals (Sweden)

    Cam GREY

    Full Text Available ABSTRACT This paper explores the links between travel and power that the journeys of Hadrian in the Vita Hadriani reveal, and suggests that these links have broader implications for our interpretation of the Historia Augusta as a whole, and of its author's literary skill and political awareness. It offers a close reading of the contexts in which Hadrian is depicted traveling in the Vita Hadriani, and argues that they may be interpreted as part of an internal dialog over alternate strategies for expressing and legitimating imperial power. It suggests that it is the moments when Hadrian is in the act of traveling that provide the clearest clues as to our author's attitude towards appropriate behavior by an emperor.

  12. Effective Design and Evaluation of Serious Games: The Case of the e-VITA Project (United States)

    Pappa, Dimitra; Pannese, Lucia

    Learning and training are presently facing new challenges and a strong transformation. The use of electronic games for education (game-based learning) promotes an agile, immersive and stimulating form of learning that fosters learner engagement and motivation. Nonetheless, the design of effective and engaging educational games is a creative process that is unique to each situation. This paper discusses the inherent challenges of building intellectually appropriate and engaging games and presents the methodology adopted in the case of the e-VITA project that applies GBL to promote knowledge sharing and transfer for intergenerational learning. The paper analyses the e-VITAframework for SGs evaluation, which is central to the project's iterative development approach. Early findings stemming from the validation of the e-VITA prototype game are also presented.

  15. St Mildrith or the monastic life against all odds in Goscelin's Vita Deo dilectae virginis Mildrethae

    Directory of Open Access Journals (Sweden)

    Alenka Divjak


    Full Text Available This paper discusses St Mildrith (dies natalis*, 13 July, +732/733 in Goscelin's Vita Deo dilectae virginis Mildrethae, the abbess of the famous monastery Minster-in-Thanet, Kent, and a consecrated virgin descended from the Kentish and Mercian royal families. The emphasis of the paper is on the examination of a limited number of hagiographic elements which stress most pointedly Mildrith's associations with monasticism and which are viewed in the broader perspective of Anglo-Saxon female sanctity.

  16. La narrazione autobiografica fra cura e liberazione. La vita di Janet Frame.

    Directory of Open Access Journals (Sweden)

    Francesca Borruso


    Full Text Available L’autobiografia, in qualità di fonte storiografica, può offrirci una pluralità di informazioni sul piano storico-educativo, che possono riguardare gli stili di vita, i modelli educativi, la vita materiale, le mentalità collettive, i comportamenti e i vissuti presenti in un determinato contesto e momento storico. L’autobiografia, inoltre, nella sua accezione di scrittura di sé,  mostra il suo volto di percorso di costruzione dell’identità, o più semplicemente di cura di sé. Nel saggio è analizzata, in questa duplice prospettiva, l’autobiografia di Janet Frame, scrittrice neozelandese contemporanea, la cui narrazione diventa una preziosa fonte per far emergere nella ricerca storico-educativa tasselli relativi alla storia delle donne.  Campo del sapere quest’ultimo, ancora oggi poco conosciuto a causa della scarsa visibilità o del difficile reperimento delle fonti. Negli ultimi anni, però, il perimetro di reperimento delle fonti relativo alle scritture femminili si stia ampliando notevolmente, consentendo al ricercatore di dare vita a nuove frontiere epistemologiche. 

  17. The linear shade guide design of Vita 3D-master performs as well as the original design of the Vita 3D-master. (United States)

    Corcodel, N; Rammelsberg, P; Jakstat, H; Moldovan, O; Schwarz, S; Hassel, A J


    Visual tooth colour assessment by use of the Vita 3D-Master(®) (3D; Vita Zahnfabrik, Bad Säckingen, Germany) is well documented. To improve handling, a new linear arrangement of the shade tabs has been introduced (LG; Linearguide 3D-Master(®) ). The purpose of this study was to investigate whether the linear design has an effect on shade matching. Fifty-six students underwent identical, theoretical and practical training, by use of an Internet learning module [Toothguide Training Software(®) (TT)] and a standardised training programme [Toothguide Training Box(®) (TTB)]. Each student then matched 30 randomly chosen shade tabs presented in an intra-oral setting by a standardised device [Toothguide Check Box(®) (TCB)]; 15 matches were made using the 3D and 15 using the LG shade guide system, under a daylight lamp (840 matches for each guide). It was recorded to what extent the presented and selected shade tabs, or the lightness group of the tabs, matched, also the needed time for colour matching. The results showed that 35% of perfect matches were observed for the 3D and 32% for the LG. The lightness group was correct in 59% of cases for 3D and 56% for LG. Mean time needed for matching of tabs and lightness group was no different between groups (no significant difference for any assessment). Within the limitations of the study design, the colour assessment with regard to performance and time needed in shade matching was not different with the LG or the 3D. Therefore, the user should choose which shade tab arrangement is more applicable. © 2010 Blackwell Publishing Ltd.

  20. Vita storpia

    Directory of Open Access Journals (Sweden)

    Cristian Fuschetto


    Full Text Available Transability is a body project aimed at acquiring a disability. By regarding disability as an object of desire, the transabled community reverses the dominant characterization of disability. Apart from medical and psychological considerations, transability is an interesting phenomenon also from a philosophical point of view, because it shows the post-modern conflict between body and life. The author first mentions body art, in order to show how this artistic movement makes it clear that the body has been engaging a sort of struggle against life in the last decades. Life seems to be a redundant energy that could be used to create new hybrid forms. Based on the concept of “Antropotechnology” by Peter Sloterdijk and “de-somatics” by the Barbara Duden, transability is considered as the phenomenon where the fight between life and body becomes even more extreme.

  1. Determination of VITA Classical shades with the 3D-Master shade guide. (United States)

    Hassel, Alexander J; Zenthöfer, Andreas; Corcodel, Nicoleta; Hildenbrandt, Achim; Reinelt, Gerhard; Wiesberg, Stefan


    Because of its good matching performance the VITA 3D-Master shade guide (3D) is frequently used for determination of tooth color. Numerous composites/ceramics are, however, available in VITA Classical (VC) shades only. The objective of this study was to investigate the possibility of performing a shade match with 3D Master and converting this result via a table in a VC shade (indirect method) without this resulting in an apparent inferior shade matching in comparison with direct shade matching with the VC. Experiments were performed with an artificial, computer-generated tooth color space. Conversion tables were generated by calculating the color difference (ΔE) between a 3D shade and the closest VC shade (simple conversion table) and with the aid of optimization procedures. Statistical differences between the direct and indirect methods and between the indirect methods were assessed by use of a U-test. Median ΔE was 2.38 for direct matching with the VC and 2.86 for indirect matching by use of a simple conversion table (p < 0.01). Optimized tables performed slightly better (median ΔE = 2.81). Within the limitations of the study, it is usually possible to determine tooth color with the 3D and convert it, via a table, into a VC shade without adding a clinically apparent error to the direct shade match with the VC.

  2. Renaissance Medicine, Magic, and Alchemy in Benvenuto Cellini’s Vita

    Directory of Open Access Journals (Sweden)

    Yuri Rudnev


    Full Text Available The article aims to rethink the several stereotypes of Romantic tradition, which are still reproduced in regard to Benvenuto Cellini and his Vita. Using the approaches of intellectual history and iconographical studies, the present study pays attention to the coherent system of lay, scientific and ‘secret’ knowledge of the epoch lurking under the surface of the simplicity and even naivety of the author’s language. I argue that this autobiographical writing embodies a certain type of culture of the self deeply rooted in contemporary medical, alchemical and magical contexts. Organized around the concept of “getting pleasure,” Cellini’s practices of the self are built into the Neo-Platonic picture of the world. Analyzing the two passages of Vita, I demonstrate the author’s spiritual ascent from the corporeal suffering to union with ‘the One’ by means of individual and collective magic rituals, transforming his Life into a work of art.

    Full Text Available The author of Vita Fructuosi, probably a monk follower of Saint Fructuosus of Braga in the area of Gallaecia, shows in this biography an evident sense of rooting in the monastic Tradition, specially in the Egyptianeastern one, and also he declares a strong Roman-Catholic and Hispanic conscience. As the highest expression of it, he presents Saint Fructuosus with the same merits of the Egyptian monks and, joined to Saint Isidorus of Seville, as a light for Spain, for the Western and for the whole Catholic Church: they both are two causes of glory for a Visigothic Spain which fells herself as Roman and Catholic.El autor de la Vita Fructuosi, al parecer un monje discípulo de San Fructuoso de Braga en el área de Gallaecia, muestra en esta biografía un claro sentido de arraigo en la Tradición monástica, especialmente egipcio-oriental, y manifiesta una fuerte conciencia romano-católica e hispana. Como máxima expresión de todo ello, presenta a San Fructuoso a la altura de los méritos de los monjes egipcios y, junto con San Isidoro de Sevilla, como una lumbrera de Hispania, del Occidente y de toda la Iglesia Católica: ambos son dos motivos de gloria de la Hispania visigótica que se siente romana y católica.

    Hossein Dashti


    Full Text Available Purpose:Dental shade guides are commonly used for color determination and should be disinfected and sterilized. The purpose of this study was to evaluate the color change of Vita 3D Master shade tabs after disinfection and sterilization. Material and methods:Overall, 98 samples (shade tabs were randomly selected from 14 new, unused Vita 3D sets, including the following shades: 2M1, 3L1.5, 3M1, 3M2, 3M3, 3R1.5 and 4M1. In each set, values of 2, 3 and 4, chroma of 1, 2 and 3 and hue were selected for the comparison of different shades. All tabs were measured using the Vita Easyshade device at baseline. The first group was disinfected with Deconex and the second group was sterilized by autoclaving in a simulated annual application. All the tabs were measured again using the same device. This process was repeated to simulate 2 and 3 years of usage. Statistical analysis was conducted by repeated measures analysis of variance (ANOVA and independent t-test and paired sample t-test. Results:In the disinfected group, we observed significant differences in value and chroma in all periods (p˂0.001. However, hue showed no significant difference after the first year of simulated treatment (p=0.527, though it was significantly different in the second and third simulations (p˂0.001. In the sterilized group, all variables showed a significant difference for each year (p˂0.05. Considering total color difference (ΔE, there was a significant difference between the two groups in the first, second and third simulated years; ΔE increased in the sterilized group more than in the disinfected samples (p˂0.001.  Conclusions:  The color change of shade tabs was significant both after disinfection by a chemical solution and by sterilization through autoclaving. However, although disinfectants may not have a clinically important effect, sterilization should be considered as an interfering factor during color-matching procedure.

  8. Elements of the universe in Philo’s De Vita Mosis: Cosmological theology or theological cosmology?

    Directory of Open Access Journals (Sweden)

    Gert J. Steyn


    Full Text Available It is the intention of this article to investigate how Philo’s understanding of the universe, and particularly its four basic elements as taught by the Greek philosophers, influenced his description of the God of Israel’s world in which the Moses narrative unfolds. Given the fact that Philo was a theologian par excellence, the question can be asked whether Philo’s approach is closer to what one might call ‘theological cosmology’ or rather closer to ‘cosmological theology’? After a brief survey of Philo’s inclination to interpret Jewish history in the light of Greek cosmology, the study proceeds with his universe as symbolised in the high priest’s vestments. The τετρακτύς with its 10 points of harmony is a key to Philo’s symbolism and numerology. The article concludes that Philo is not writing cosmology per se in his De Vita Mosis, but he is rather writing a theology that sketches the cosmic superiority and involvement of Israel’s God against the backdrop of Greek cosmology as it was influenced by Pythagoras’ geometry and numerology as well as by Plato’s philosophy. In this sense his account in the De Vita Mosis is closer to a cosmological theology. He utilises the cosmological picture of the Greco-Hellenistic world in order to introduce and present the powerful nature and qualities of Israel’s God.Hierdie artikel het ten doel om ondersoek in te stel na Philo se begrip van die heelal en veral die vier basiese elemente soos dit deur die Griekse filosowe geleer is.

  9. Alessia Ricciardi, After La Dolce Vita. A Cultural Prehistory of Berlusconi’s Italy

    Directory of Open Access Journals (Sweden)

    Paolo Lago


    Full Text Available Il volume After La Dolce Vita. A Cultural Prehistory of Berlusconi’s Italy, di Alessia Ricciardi, pone sotto la sua lente critica la cultura degli anni Ottanta incentrandosi su quattro concetti fondamentali: “Sweetness”, “Lightness”, “Weakness” e “Softness”. L’ultimo Fellini, l’ultimo Calvino, Vattimo e la Transavanguardia di Bonito Oliva vengono sottoposti a una serrata indagine critica: se Fellini, con Ginger e Fred, si caratterizza come uno dei pochi artisti e intellettuali italiani a criticare la società degli anni Ottanta attraversata dal galoppante predominio televisivo berlusconiano, Calvino, Vattimo e Bonito Oliva, con le loro opere e le loro teorie, secondo Ricciardi, non fanno altro che ‘assecondare’ il consumismo imperante. Tale lettura, anche se condivisibile in alcuni momenti, risente comunque di una eccessiva rigidezza interpretativa nell’analizzare un periodo fluido e complesso come la società italiana contemporanea.

    The aim of this in vitro study was to evaluate the accuracy of shade matching using two spectrophotometric devices. Thirteen patients who require a full coverage restoration for one of their maxillary central incisors were selected while the adjacent central incisor was intact. 3 same frameworks were constructed for each tooth using computer-aided design and computer-aided manufacturing technology. Shade matching was performed using Vita Easyshade spectrophotometer, Shadepilot spectrophotometer, and Vitapan classical shade guide for the first, second, and third crown subsequently. After application, firing, and glazing of the porcelain, the color was evaluated and scored by five inspectors. Both spectrophotometric systems showed significantly better results than visual method (P spectrophotometers (P Spectrophotometers are a good substitute for visual color selection methods.

  17. Elective frozen elephant trunk procedure using the E-Vita Open Plus prosthesis in 94 patients: a multicentre French registry. (United States)

    Verhoye, Jean-Philippe; Belhaj Soulami, Reda; Fouquet, Olivier; Ruggieri, Vito Giovanni; Kaladji, Adrien; Tomasi, Jacques; Sellin, Michel; Farhat, Fadi; Anselmi, Amedeo


    Our goal was to evaluate the operative outcomes of the frozen elephant trunk technique using the E-Vita Open Plus ® hybrid prosthesis in chronic aortic arch diseases and report clinical and radiological outcomes at the 1-year follow-up. As determined from a prospective multicentre registry, 94 patients underwent frozen elephant trunk procedures using the E-Vita Open Plus hybrid device for the treatment of chronic aortic conditions, including 50% chronic aortic dissections, 40% degenerative aneurysms and 10% miscellaneous indications. Fifty percent of the cases were reoperations. The perioperative mortality rate was 11.7%. Spinal cord ischaemia and stroke rates were 4% and 9.6%, respectively. The mean cardiopulmonary bypass time was 252 ± 97 min, cardiac ischaemia time was 152 ± 53 min and cerebral perfusion time was 82 ± 22 min. Concomitant procedures were observed in 15% of patients. Among the 83 surviving patients, the survival rate after the 1-year follow-up was 98%. Eleven percent of patients underwent endovascular completion, whereas 4% of patients required aortic reintervention at 1 year. The E-Vita Open Plus hybrid device confirms the favourable short- and mid-term outcomes offered by its predecessor in frozen elephant trunk procedures in patients with chronic aortic arch disease. Implantation of the E-Vita Open Plus is associated with good 1-year survival rates, good rates of favourable aortic remodelling in both chronic dissection and degenerative aneurysms and a reproducible technique in a multicentre registry. Continued follow-up is required due to the risk of evolution at the downstream aorta.

  18. Thuja occidentalis (Arbor vitae): A Review of its Pharmaceutical, Pharmacological and Clinical Properties (United States)


    Arbor vitae (Thuja occidentalis L.) is a native European tree widely used in homeopathy and evidence-based phytotherapy. Many reviews and monographs have been published on the herbal substance's description, mode of action and clinical use. However, no comprehensive evidence-based review is available. Therefore, our aim was to search MEDLINE databases and survey manufacturers for further details or unpublished data. This review presents the botany, ethnobotany and phytochemistry, especially the different contents of essential oil (Thujone) in relation to different extraction procedures of this medicinal plant. Thuja's antiviral action and immunopharmacological potential, such as stimulatory and co-stimulatory effects on cytokine and antibody production and activation of macrophages and other immunocompetent cells, have been evaluated in numerous in vitro and in vivo investigations. Although no controlled trials have been conducted on Thuja occ alone, many clinical studies have been performed with a herbal medicinal product containing a special extract of Thuja occ and other immunostimulants, demonstrating its therapeutic efficacy and safety in respiratory tract infections.

  19. La vita è blending. Per una lettura integrata del film di Roberto Benigni

    Directory of Open Access Journals (Sweden)

    Emanuele Broccio


    Full Text Available Il notevole incremento di studi critici sulla Poetica Cognitiva sta riscattandola dall’accusa di offrire soltanto una nuova e seducente terminologia, guadagnandole invece la dignità di metodologia scientifica. Mosso dall’interesse che il fenomeno della integrazione concettuale (blending suscita, il mio intervento propone una lettura del film La vita è bella di Roberto Benigni proprio in funzione del suo organizzarsi intorno a un blending che ne sostiene l’intero impianto ideativo. Il film è stato molto criticato, oltre che per un certo impaccio tecnico nella messa in scena, per il fatto di condurre un racconto di morte e sterminio attraverso un punto di vista comico. Attraverso l’applicazione del blending, insieme ad altri strumenti di analisi classica, cercherò di dimostrare come la strutturazione del racconto intorno alla duplice contaminazione di realtà e fantasia, comico e tragico, lo sottrae dal rischio di scivolare nel melodramma e nel patetismo, mantenendo alta l’empatia dello spettatore. La mia lettura sottolinea dunque come tutto il film sia costruito su un continuo blending, e ne evidenzia le modalità di realizzazione, dimostrando, attraverso un’opera ampiamente nota e di vasto consenso, come le scienze cognitive possano offrire validi strumenti di analisi che precisano pregresse intuizioni critiche e illuminano zone dell’opera d’arte rimaste in ombra o confinate alla valutazione estetica.

Nesse sentido, trata-se de uma noção requisitada como parte do projeto crítico da modernidade implementado pelo filósofo alemão, cujo ponto de partida é uma revisão da própria tarefa da filosofia, conduzindo a uma crítica radical da moralidade vigente, da hipertrofia da racionalidade e da importância da linguagem. O silêncio, associado à solidão, aparece como uma profilaxia e radical aprofundamento em relação à anulação de si no arrulho da multidão moderna.

  2. Dalle carte dell’Archivio di Stato di Roma: notizie sulla vita e l’attività professionale di Luigi Mollari / Documents from the State Archive of Rome: news about Luigi Mollari’s life and professional activity

    Directory of Open Access Journals (Sweden)

    Sabina Carbonara


    Full Text Available Grazie al recente ritrovamento di un fascicolo nel fondo della Congregazione degli Studi conservato presso l’Archivio di Stato di Roma è stato possibile ricostruire, almeno in parte, la produzione professionale dell’ingegnere e architetto Luigi Mollari, figlio di Antonio, ad oggi ancora scarsamente indagata. I pochi studi relativi alla attività di Luigi hanno riguardato, infatti, soprattutto la sua presenza a Terracina e, nello specifico, il suo intervento, negli anni Quaranta del XIX secolo, nella chiesa del S. Salvatore, progettata da Antonio Sarti. In realtà, come si evince dal curriculum vitae rinvenuto fra i documenti d’archivio, il giovane Mollari iniziò a collaborare col padre già nel 1824. Trasferitosi a Foligno nel 1832, si occupò, sempre insieme al genitore e su incarico di monsignor Ignazio Giovanni Cadolini, degli edifici danneggiati dal terremoto. Nello stesso anno Luigi è documentato anche ad Assisi dove coadiuva il padre nella direzione dei primi interventi di consolidamento statico e di riparazione della basilica di S. Maria degli Angeli. Fra il 1832 e il 1834 i due Mollari interverranno, con opere di ricostruzione e di restauro, in numerosi edifici del territorio fulignate. Dopo la morte di Antonio, avvenuta nel 1843, Luigi continuerà a svolgere l’attività di architetto e ingegnere a Terracina e nel territorio limitrofo (in particolare a Piperno, oggi Priverno. Thanks to the recent discovery of a folder at the Congregation of Studies, preserved in the State Archives of Rome, it has been possible to reconstruct, at least partially , the professional production of Luigi Mollari, engineer and architect , son of Antonio, till now poorly investigated. The few studies concerning the activities of Luigi were, in fact , especially its presence in Terracina and, specifically , its involvement, in the forties(of the 19th century, in the church of St. Salvatore, designed by Antonio Sarti.

    The US National Conference of Catholic Bishops' Committee for Pro-Life Activities reaffirm the 25-year old "Humanae Vitae." According to the secular world, sexual intercourse is a natural response to human instinct and need and contraception is a means to separate sexual intercourse from unwanted pregnancy and to free people from religious teachings. The true nature of human sexuality is understanding of human life and the human spirit. Sexual intercourse cannot be disconnected from the nature and dignity of human life and the means by which life is conveyed. The foundation of this encyclical is natural law as revealed by God. The Catholic church upholds this law through its teachings. Sexual intercourse is a couple's dignified expression of love for one another. Marital love reflects God's love, so marriage leads to union with God. Love between spouses stabilizes marriage and allows couples to make responsible decisions about birth spacing and family size. They celebrate their love via sexual intercourse and are open to life each time they have intercourse. There are 2 inseparable goods of marital intercourse: procreation and strengthening of interpersonal unity. Married couples want to share their life and love in creating new life and building a family . Parenthood is both a privilege and responsibility. Each child is a child of God with invaluable dignity who God calls to fulfill his/her human destiny and to be active in the Church's mission. Responsible parenthood intimates openness to life. Parents should be free to make family planning decisions while considering their duty to God, themselves, family, and society. Unproven claims about population growth and cultural attitudes debasing the value of children comprise the couple's freedom. Nonmarital cohabitation, abortion, illegitimate pregnancy, and divorce reflect confusion over human sexuality. The family is the basic unit of society. Natural family planning allows couples to have a richer appreciation of

    Full Text Available Il Polibutene-1 isotattico (i-PB1 è un materiale polimerico usato per la produzione di tubi per il trasporto di fluidi in pressione. In questo lavoro si sono studiati due tipi di i-PB1 prodotti da Basellche differiscono per grado di isotatticità.Si sono condotte prove di frattura a diverse temperature e velocità di spostamento imposte. Si è utilizzata una configurazione di flessione su provini con singolo intaglio (SENB unitamente a quella di doppia trave a sbalzo (DCB, quest’ultima limitatamente allo studio della fase di propagazione. Al fine di individuare con precisione l’innesco della frattura e la velocità di propagazione della stessa si è fatto ricorso a metodi ottici. Dal punto di vista fenomenologico durante la propagazione si assiste alla formazione di zone in cui il materiale risulta fortemente stirato. La frattura in esse avanza con una lacerazione continua che si alterna a salti repentini in occasione del brusco cedimento di queste zone, associato a conseguenti cadute del carico. Questaparziale instabilità è stata osservata sui due materiali per entrambe le configurazioni di prova.I risultati ottenuti sono stati interpretati seguendo l’approccio della meccanica della frattura e applicando uno schema di riduzione di tipo tempo-temperatura che ha permesso di descrivere il comportamento viscoelastico del materiale su un intervallo temporale di diverse decadi.I risultati hanno permesso di applicare un modello analitico per la previsione della vita utile di tubi in pressione.Il modello si è mostrato in buon accordo con i dati sperimentali disponibili da prove condotte su tubi dello stesso materiale.

  7. Poverty and richly decorated garments : a re-evaluation of their significance in the Vita Christi of Isabel de Villena


    Twomey, Lesley


    This output addresses the interest Isabel de Villena shows in the Vita Christi in rich clothing; contrasting it with the garments described as ‘fitting for nuns to wear in the Rule of St Clare’. Unlike previous criticism of Villena’s work, this chapter points to the way in which she draws on local depictions of the Virgin for her inspiration for fine garments and rejects her interest in jewellery and embroidered garments as being evidence of a feminine approach to writing. The study fits with...

    Full Text Available Este artigo visa discutir aspectos da educação dos leigos no reino visigodo no século VII, tendo como pressuposto que, diante da reorganização eclesiástica em curso, o processo educacional teria se identificado com o trabalho de cristianização. Nesse sentido, compreendemos que teria se manifestado em espaços sociais variados. Para explicitar a questão, analisamos uma hagiografia produzida no século VII pelo Bispo Bráulio de Saragoça, Vita Sancti Aemiliani. Na abordagem deste documento, observamos seu caráter pedagógico, bem como traços da afirmação de um modelo educacional que valoriza demaneira singular o papel do mestre.The intention of this article is to study laymen education in the7th century Visigothic kingdom, starting from the assumption that, faced with the ecclesiastical reorganization under way, the educational process would identify with the work of Christianization. In that sense, it is understood that it would have manifested inseveral social spaces. To explain this question, we analyze a hagiography produced in the 7th century by the bishop Braulio of Saragossa, Vita Sancti Aemiliani. In investigating this document, we observe its pedagogical character, as well as traces of the affirmation of an educational model that especially values the role of master.

  10. Tedium vitae, death wishes, suicidal ideation and attempts in Kenya-prevalence and risk factors. (United States)

    Jenkins, Rachel; Othieno, Caleb; Omollo, Ray; Ongeri, Linnet; Sifuna, Peter; Ongecha, Michael; Mboroki, James Kingora; Kiima, David; Ogutu, Bernhards


    There has been no previous household population study of suicidal ideation and attempts in Kenya. Therefore this study aimed to establish the prevalence of suicidal ideation and attempts in a rural population in Kenya, and to assess risk factors. An epidemiological survey of a household population, using standardised structured interviews. We examined the prevalence of suicidal ideation and suicide attempts and the predictors of suicidal thoughts and attempts, using STATA to calculate unadjusted and adjusted odds ratios. A quarter of the sample (24.1 %) had thought that life was not worth living (tedium vitae) at some point in their lives, while a fifth had experienced death wishes at some stage. About 7.9 % reported suicidal thoughts and 1.9 % had made actual suicide attempts at some point in their lives. It can be seen that the prevalence of suicidal thoughts was 0.7 %, 4.2 %, 3.7 % and 7.9 % for last week, last year, at some other time, and lifetime respectively, while the prevalence of suicidal attempts was 0.5 %, 1.2 %, 0.7 and 1.9 % respectively. In the adjusted analysis of factors associated with suicidal thoughts, being female (OR 1.8, p = 0.017), having CMD (OR 2.7, p = 0.001), having a number of recent life events (OR 2.3, p = 0.001 for 2-3 life events and OR 2.6, p = 0.004 for 4 or more life events), and having a large social group size (OR 7.7, p = 0.006 for social group size of 4-8 and OR 9.1, p = 0.003 for social group size of 9 or more) were all associated with increased rates of life time suicidal thoughts, but psychotic symptoms were no longer significant after adjustment for the other variables. In the adjusted analysis of suicide attempts, having any psychotic symptoms (OR 5.1, p = 0.001) was the only factor associated with suicide attempts after adjustment for other factors significant at the bivariate level. Suicidal ideation and attempts pose a significant public health burden in this poor rural area of Kenya. The findings are relevant for

  11. Engineering the curriculum: Towards an adaptive curriculum (United States)

    Johns-Boast, Lynette Frances

    The curriculum is one of the most important artefacts produced by higher education institutions, yet it is one of the least studied. Additionally, little is known about the decision-making of academics when designing and developing their curricula, nor how they make use of them. This research investigates how 22 Australian higher education engineering, software engineering, computer science, and information systems academics conceive of curriculum, what approaches they take when designing, and developing course and program curricula, and what use they make of the curriculum. It also considers the implications of these conceptions and behaviour upon their curricula. Data were collected through a series of one-to-one, in-depth, qualitative interviews as well as small focus group sessions and were analysed following Charmaz’ (2006) approach to grounded theory. In this thesis, I argue that the development of curricula for new higher degree programs and courses and / or the updating and innovating of an existing curriculum is a design problem. I also argue that curriculum is a complex adaptive system. Surrounding the design and development of a curriculum is a process of design that leads to the creation of a designed object – the official-curriculum. The official-curriculum provides the guiding principles for its implementation, which involves the design and development of the curriculum-in-use, its delivery, and evaluation. Data show that while the participants conceive of curriculum as a problem of design involving a design process leading to the development of the official-curriculum, surprisingly, their behaviour does not match their conceptions. Over a very short period, their behaviour leads to a process I have called curriculum drift where the official-curriculum and the curriculum-in-use drift away from each other causing the curriculum to lose its integrity. Curricular integrity is characterised through the attributes of alignment, coherence, and

  13. Accuracy of shade matching performed by colour blind and normal dental students using 3D Master and Vita Lumin shade guides. (United States)

    Vafaee, F; Rakhshan, V; Vafaei, M; Khoshhal, M


    The purpose of this study was to investigate whether 3D Master or VitaLumin shade guides could improve colour selection in individuals with normal and defective colour vision. First, colour perception of 260 dental students was evaluated. Afterwards, 9 colour blind and 9 matched normal subjects tried to detect colours of 10 randomly selected tabs from each kit and the correct/false answers were counted. Of the colour-defective subjects, 47.8% and 33.3% correctly detected the shade using 3D Master and VitaLumin, respectively. These statistics were 62.2% and 42.2% in normal subjects. In normal participants, but not in colour blind ones, 3D Master significantly improved shade matching accuracy compared to VitaLumin.

    Full Text Available La volgarizzazione della Vita di Esopo a opera di Giulio Landi (1545 è stata caratterizzata da una lunga fortuna che ne ha fatto l’introduzione biografica “ufficiale” per secoli alle favole. Nondimeno, la traduzione del Landi era nata come testo autonomo, come chiaramente attestato dal paratesto. La Vita può essere letta su tre diversi livelli (comico, politico, filosofico-religioso che per essere compresi debbono essere ricondotti tanto all’ambiente piacentino, specie con l’ambigua accademia degli Ortolani, quanto all’intera produzione del Landi e alla sua rete intellettuale. The translation into Italian of the Aesopus’ Life by Giulio Landi (1545 has enjoyed a centuries-long diffusion as the standard biographic introduction to the Aesop’s fables. Actually, the paratext clearly certifies that Landi’s work was born as an autonomous text. The Life proposes three different levels of reading: comical, political, religious-philosophical. All of them have to be read in the frame both of the Piacenza milieu (mainly with the ambiguous Accademia degli Ortolan and of the whole Landi’s production and cultural network.

    Fazi, Giovanni; Vichi, Alessandro; Corciolani, Gabriele; Ferrari, Marco


    To determine by a spectrophotometric analysis the variations in color between the fabricated shade of four different porcelain systems and the intended shade when applied in a set thickness. Four porcelain systems (Duceram Kiss, VITA Omega, Wieland Reflex, Ivoclar IPS d.SIGN) for metal ceramic restorations were selected. Three disk-shaped (15 mm diameter, 0.3 mm thickness) specimens per group were made for three different shades of the A color scale of the Vitapan classical shade guide. On a Cr-Co alloy, 0.15 mm of porcelain opaque and 1.0 mm of translucent porcelain was applied. The porcelain stratification was executed according to the manufacturers' indications. The color measures were made by the clinical spectrophotometer Easyshade. No statistically significant differences were found among the ceramic systems examined. The recorded differences in color between A2 porcelain disks and corresponding VITA shade tabs were closer (mean delta E = 2.50) than those recorded for shade A3 (mean delta E = 3.84) and shade A3.5 (mean delta E= 3.94) (P<0.05).

    Asadollah Ahmadzade

    Full Text Available Introduction: This study aims at comparing and analyzing the shear bond strength of the two zirconia cores on two porcelains proposed by the manufacturing company in two systems of VITA and IVOCLARMaterials & Methods: In this laboratory study, at first the tooth-like brass sample was made by the CNC machine. Then, using the CAD CAM machine, 20 zirconia cores of Vita in Ceram YZ Cubes and 20 zirconia cores of IPS e. max zirCAD were provided. Half of the cores were provided using Vita VM9 porcelain and the other half were veneered with the use of IPS e. max ceram. In groups one to four, Vita Core and Veneer, Vita Core and Ivoclar Veneer, Ivoclar Core and Vita Veneer, and Ivoclar Core and Veneer were used respectively. Afterwards, the samples were put under the static force in the Universal Test machine (UTM with the speed of 0/5 mm per minute to bring about fracture. The type of fracture was determined by electronic microscope. Schmitz-Schulmeyer Test was applied to evaluate the shear bond strength of core-veneer. In order to analyze the data, Two-Way ANOVA and logestic regression were carried out using SPSS 19 (α=0. 05.Results: The rate of shear bond strength for groups one to four were 10.852.67, 10.353.30, 10.353.30 and 6.722.47 mega pascal respectively. The type of core had no effects on shear bond strength (P=0. 869, but the veneer kind was important in the rate of shear bond strength (P=0.027. The Vita veneer showed a higher level of shear bond strength. After the microscopic evaluation, samples showed a combination of the cohesive fracture at the veneer layer and mixed (cohesive, adhesive fracture at the edge of the two layers; No adhesive fracture between the zirconia cores and veneers was observed. Conclusion: The results show that the shear bond strength of zirconia core and the covering porcelain veneers and the fracture type are not influenced by the core type, but are affected by the type of veneer.

  5. A "three-in-one" sample preparation method for simultaneous determination of B-group water-soluble vitamins in infant formula using VitaFast(®) kits. (United States)

    Zhang, Heng; Lan, Fang; Shi, Yupeng; Wan, Zhi-Gang; Yue, Zhen-Feng; Fan, Fang; Lin, Yan-Kui; Tang, Mu-Jin; Lv, Jing-Zhang; Xiao, Tan; Yi, Changqing


    VitaFast(®) test kits designed for the microbiological assay in microtiter plate format can be applied to quantitative determination of B-group water-soluble vitamins such as vitamin B12, folic acid and biotin, et al. Compared to traditional microbiological methods, VitaFast(®) kits significantly reduce sample processing time and provide greater reliability, higher productivity and better accuracy. Recently, simultaneous determination of vitamin B12, folic acid and biotin in one sample is urgently required when evaluating the quality of infant formulae in our practical work. However, the present sample preparation protocols which are developed for individual test systems, are incompatible with simultaneous determination of several analytes. To solve this problem, a novel "three-in-one" sample preparation method is herein developed for simultaneous determination of B-group water-soluble vitamins using VitaFast(®) kits. The performance of this novel "three-in-one" sample preparation method was systematically evaluated through comparing with individual sample preparation protocols. The experimental results of the assays which employed "three-in-one" sample preparation method were in good agreement with those obtained from conventional VitaFast(®) extraction methods, indicating that the proposed "three-in-one" sample preparation method is applicable to the present three VitaFast(®) vitamin test systems, thus offering a promising alternative for the three independent sample preparation methods. The proposed new sample preparation method will significantly improve the efficiency of infant formulae inspection. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Cassidy, David C


    Il genio di Werner Heisenberg attraversa l'orizzonte della fisica del nostro secolo come una meteora. Testimoniano della fecondità e dell'originalità del suo pensiero non solo il Nobel che gli fu assegnato a soli 32 anni, ma soprattutto i decisivi impulsi da lui dati alla fisica quantistica, alla teoria delle particelle elementari, alla teoria del nucleo. Si deve a Heisenberg quel "principio di indeterminazione" che ha rivoluzionato non solo il corso della fisica ma il modo di concepire la posizione dell'uomo nell'universo. L'interesse del libro, però, vuole andare oltre la fisica, giacché il curriculum del "ragazzo di campagna dei biondi capelli" rispecchia in forma emblematica l'ambiguo rapporto della scienza col potere.

  17. What does the Development of the European Core Curriculum for Cardiovascular Nurses Mean for Australia? (United States)

    Neubeck, Lis; Lin, Stella Hsi-Man; Ferry, Cate; Gallagher, Robyn


    A core curriculum for the continuing professional development of nurses has recently been published by the Council on Cardiovascular Nursing and Allied Professions of the European Society of Cardiology. This core curriculum was envisaged to bridge the educational gap between qualification as a nurse and an advance practice role. In addition, the shared elements and international consensus on core themes creates a strong pathway for nursing career development that is directly relevant to Australia. Education programs for nurses in Australia must meet the mandatory standards of the Australian Nursing and Midwifery Accreditation Council (ANMAC), but without a national core curriculum, there can be considerable variation in the content of such courses. The core curriculum is developed to be adapted locally, allowing the addition of nationally relevant competencies, for example, culturally appropriate care of Aboriginal and Torres Strait Islander individuals. Two existing specialist resources could be utilised to deliver a tailored cardiovascular core curriculum; the Heart Education Assessment and Rehabilitation Toolkit (HEART) online ( and HeartOne ( Both resources could be further enhanced by incorporating the core curriculum. The release of the European core curriculum should be viewed as a call to action for Australia to develop a core curriculum for cardiovascular nurses.

  3. “Altrove che nella verità?”. Filosofia, scienza e vita nel pensiero di Georges Canguilhem

    Directory of Open Access Journals (Sweden)

    Daniele Poccia


    Full Text Available Secondo Georges Canguilhem non c’è verità se non quella prodotta e non scoperta dalla scienza. È il valore stesso della filosofia ad essere “altrove che nella verità”. Questo valore non veritativo risiede forse, per il pensatore francese, in qualcosa che egli definisce come un senso o un concetto iscritto materialmente nella vita. È il vivente stesso, quel vivente di cui la scienza in quanto ricerca della verità è a sua volta una semplice espressione, a contenere il concetto, o meglio, ad essere il movimento stesso della concettualizzazione. “Elsewherethan in the truth?” Philosophy, science and life in Georges Canguilhem'sthought. Accordingto Georges Canguilhem thereis no truththan the oneyieldedbutnotdiscoveredby science. Being “Elsewherethan in the truth” is the valueitselfofphilosophy”.

[Institute of Physics, Chinese Academy of Sciences, Beijing 10081 (China); Zhang, X.-G., E-mail: [Department of Physics and Quantum Theory Project, University of Florida, Gainesville, Florida 32611 (United States); Center for Nanophase Materials Sciences and Computer Science and Mathematics Division, Oak Ridge National Laboratory, Oak Ridge, Tennessee 37831-6493 (United States)


    Classical magnetoresistance (MR) in nonmagnetic metals are conventionally understood in terms of the Kohler rule, with violation usually viewed as anomalous electron transport, in particular, as evidence of non-Fermi liquid behavior. Measurement of the MR of Au films as a function of temperature and film thickness reveals a strong dependence on grain size distribution and clear violation of the Kohler rule. Using a model of random resistor network, we show that this result can be explained if the MR arises entirely from inhomogeneity due to grain boundary scattering and thermal activation of grain boundary atoms. Consequently, the Kohler rule should not be used to distinguish normal and anomalous electron transport in solids.

  14. A comparison on the flexural strength of a new dental porcelain (D.} Dentin with Vita company Dentin porcelain (VMK 68N

    Directory of Open Access Journals (Sweden)

    Ghahramanloo A.


    Full Text Available Statement of Problem: Dental porcelain is one of the best materials ever used in dentistry. Excellent tissue"ncompatibility, esthetics, very low solubility in oral fluids, high compressive strength, and the lowest bacterial"nplaque accumulation on the glazed porcelain are some of its advantages. Porcelain brittleness due to its low"ntensile strength, impact strength and the occlusal attrition of opposing teeth enamel are some of its"ndisadvantages. The most important mechanical properties of dental porcelains are their flexural strength that is"nthe ability of a porcelain to resist fracture when loaded from above. Different ways have been proposed to"neliminate porcelain brittleness and develop its flexural strength, among which baking porcelain on a metal"nframework is more commonly used."nPurpose: Considering that restoration and replacement of teeth by porcelain fused to metal restorations is still"nthe most commonly used technique, the aim of the present study was to measure the flexural strength of a"nporcelain bonded to metal powder, D4 Dentin, and to compare it with Vita Dentin powder."nMaterials and Methods: In this experimental study, a stainless steel box, 25x5x2mm was made according to"nISO 6872: 1995 (E Standard and filled with D4 Dentin powder and Vita Dentin (VMK 68N and baked in"nVita furnace. Then 10 blocks of D^ Dentin and 10 of Vita Dentin were made. Samples were placed on the"nthree point bending test machine and force was applied the middle of each block. To analyze the data, t-"nstudent test and co-variance analysis were used."nResults: Mean flexural strength of D4 Dentin was 53.40±1.35 MPa and that of Vita Dentin was 53.86+7.38"nMPa. The difference was not statistically significant."nConclusion: According to ISO 6872: 1995 (E standard, the flexural strength of all D4 Dentin samples were"ngreater than 50 Mpa.

  16. Thematic curriculum approach

    Directory of Open Access Journals (Sweden)

    Šefer Jasmina P.


    Full Text Available Thematic curriculum combines disciplines and media. The process is problem-oriented and the scenario most often follows the logic of exploring or storytelling. Those two approaches to teaching are appropriate because they fit into interdisciplinary and creative open-ended problem solving through play, as insisted upon by thematic curriculum. The matrix, where seven types of abilities intersect with five types of problems according to their degree of openness, defines well the outcomes of teaching. However, it did not prove to be suitable for planning the majority of activities in thematic curriculum, for it follows with difficulty the process of exploring or storytelling i.e. it disrupts the subject matter coherence of thematic curriculum. Therefore, it is suggested that matrix should be used for disciplinary curriculum planning but for that of thematic curriculum only in exclusive cases. The matrix should be used primarily as a framework for evaluating the distribution of various types of abilities and problem situations in teaching. The logic of diverse approaches to teaching reflects itself in the manner of planning and organizing the teaching process. Conceptual, visual-graphic, structural and other aids employed during educational process planning should suit the nature of the approach chosen. On the basis of qualitative investigations of educational process, in the present paper considerations are given to various approaches to teaching development of various drafts for the planning of teaching, and recognition of the logic of storytelling and exploring in thematic curriculum.

  17. Multifragmentation in Au + Au collisions studied with AMD-V

    Energy Technology Data Exchange (ETDEWEB)

    Ono, Akira [Tohoku Univ., Sendai (Japan). Faculty of Science


    AMD-V is an optimum model for calculation of multifragmentation in Au + Au collisions. AMD-V consider anti-symmetry of incident nucleus, target nucleus and fragments, furthermore, it treat the quantum effect to exist many channels in the intermediate and final state. 150 and 250 MeV/nucleon incident energy were used in the experiments. The data of multifragment atom in {sup 197}Au + {sup 197}Au collisions was reproduced by AMD-V calculation using Gognny force, corresponding to the imcompressibility of nuclear substance K = 228 MeV and its mean field depend on momentum. When other interaction (SKG 2 force, corresponding to K = 373 KeV) was used an mean field does not depend on momentum, the calculation results could not reproduce the experimental values, because nucleus and deuteron were estimated too large and {alpha}-particle and intermediate fragments estimated too small.

  20. Chiral magnetic effect search in p+Au, d+Au and Au+Au collisions at RHIC (United States)

    Zhao, Jie; STAR Collaboration


    The chiral magnetic effect (CME) is a fundamental property of QCD. A major background source for CME measurements is the intrinsic particle correlations (such as resonances/jets decay) coupled with the azimuthal elliptical anisotropy v2. In heavy-ion collisions, the magnetic field direction and event plane azimuthal angle Ψ2 are correlated, thus the CME and the v2-induced background are entangled. In small system p+Au and d+Au collisions, the Ψ2 is mostly due to geometry fluctuations, and thus magnetic field direction and Ψ2 are uncorrelated. The correlation measurements in small system collisions with respect to Ψ2 are only sensitive to v2-induced background while any CME is averaged to zero. In this talk, we will present the STAR measurements of two-particle correlations with respect to Ψ2 in p+Au, d+Au and Au+Au collisions at √{sNN} = 200 GeV. These results are analyzed as a function of particle multiplicity to shed light on the background contaminations of the CME measurements in heavy-ion collisions. We will also report results from a new analysis approach as a function of the particle pair invariant mass in order to suppress non-CME related physics backgrounds.

  2. Borophene synthesis on Au(111) (United States)

    Guisinger, Nathan; Kiraly, Brian; Zhang, Zhuhua; Mannix, Andrew; Hersam, Mark C.; Yakobson, Boris I.

    The recent experimental discovery of borophene, the metallic 2-dimensional allotrope of boron, has sparked tremendous interest in further exploration of this unique material. The initial synthesis of borophene was accomplished on Ag substrates and serves as a quintessential example of predictive modeling to experimental realization. In this talk, we expand the phase-space of borophene synthesis to Au. Borophene synthesis was accomplished by evaporating elemental boron onto a Au(111) substrate. The synthesized borophene retains its metallic character on Au as verified with scanning tunneling spectroscopy. Most fascinating is the difference in growth dynamics on the Au(111) substrate where the reconstructed surface presents a unique energy landscape for borophene nucleation and growth. We find that the initial low-coverage growth of borophene modifies the herringbone reconstruction into a ``trigonal'' network, where the 2D boron islands are uniformly templated across the surface. Increasing coverage results in the increasing size of the templated borophene islands until they coalesce into larger sheets. The observed growth dynamics are supported by the computational modeling of boron nucleation on Au.

  10. Influence of Light Conditions and Light Sources on Clinical Measurement of Natural Teeth Color using VITA Easyshade Advance 4,0® Spectrophotometer. Pilot Study. (United States)

    Posavec, Ivona; Prpić, Vladimir; Zlatarić, Dubravka Knezović


    The purpose of this study was to evaluate and compare lightness (L), chroma (C) and hue (h), green-red (a) and blue-yellow (b) character of the color of maxillary right central incisors in different light conditions and light sources. Two examiners who were well trained in digital color evaluation participated in the research. Intraclass correlation coefficients (ICCs) were used to analyze intra- and interobserver reliability. The LCh and L*a*b* values were determined at 08.15 and at 10.00 in the morning under three different light conditions. Tooth color was assessed in 10 subjects using intraoral spectrophotometer VITA Easyshade Advance 4.0® set at the central region of the vestibular surface of the measured tooth. Intra- and interobserver ICC values were high for both examiners and ranged from 0.57 to 0.99. Statistically significant differences in LCh and L*a*b* values measured in different time of the day and certain light condition were not found (p>0.05). Statistically significant differences in LCh and L*a*b* values measured under three different light conditions were not found, too (p>0.05). VITA Easyshade Advance 4.0® is reliable enough for daily clinical work in order to assess tooth color during the fabrication of esthtic appliances because it is not dependent on light conditions and light sources.

    Directory of Open Access Journals (Sweden)

    Karin Kleiner


    Full Text Available We describe a multiscale modeling hierarchy for the particular case of Au-island ripening on Au(100. Starting at the microscopic scale, density functional theory was used to investigate a limited number of self-diffusion processes on perfect and imperfect Au(100 surfaces. The obtained structural and energetic information served as basis for optimizing a reactive forcefield (here ReaxFF, which afterwards was used to address the mesoscopic scale. Reactive force field simulations were performed to investigate more diffusion possibilities at a lower computational cost but with similar accuracy. Finally, we reached the macroscale by means of kinetic Monte Carlo (kMC simulations. The reaction rates for the reaction process database used in the kMC simulations were generated using the reactive force field. Using this strategy, we simulated nucleation, aggregation, and fluctuation processes for monoatomic high islands on Au(100 and modeled their equilibrium shape structures. Finally, by calculating the step line tension at different temperatures, we were able to make a direct comparison with available experimental data.

  15. Curriculum, curriculum development, curriculum studies? Problematising theoretical ambiguities in doctoral theses in the education field

    Directory of Open Access Journals (Sweden)

    Petro du Preez


    Full Text Available Theoretical ambiguities in curriculum studies result in conceptual mayhem. Accordingly, they hinder the development of the complicated conversation on curriculum as a verb. This article aims to contribute to reconceptualizing curriculum studies as a dynamic social practice that aspires to thinking and acting with intelligences and sensitivity so as to understand oneself and others. It also raises awareness that equating all forms of research on curriculum with curriculum studies dilutes the scope of the conversation. This exploration asks two key questions: What is the nature of doctoral theses in the field of education's theoretical contributions to nuances of curriculum (curriculum, curriculum development, and curriculum studies? In what ways do these theses perpetuate or even add to current ambiguities in the discipline of curriculum studies? The exploration of these two questions draws on a critical meta-study of 511 theses completed in South African universities (2005-2012 conducted using a three level process. It appears that the main detractions of these theses are that some of them see curriculum studies as a dumping ground and others make no theoretical contribution to the discipline. The article concludes by suggesting ways which would encourage the intellectual advancement of curriculum studies through rigorous disciplinarity.

    The system created in non-central relativisticnucleus-nucleus collisions possesses large orbital angular momentum. Dueto spin-orbit coupling, particles produced in such a system could becomeglobally polarized along the direction of the system angular momentum. Wepresent the results of Lambda and anti-Lambda hyperon global polarizationmeasurements in Au+Au collisions at sqrt sNN=62.4 GeV and 200 GeVperformed with the STAR detector at RHIC. The observed globalpolarization of Lambda and anti-Lambda hyperons in the STAR acceptance isconsistent with zero within the precision of the measurements. Theobtained upper limit, lbar P Lambda, anti-Lambda rbar<= 0.02, iscompared to the theoretical values discussed recently in theliterature.

  19. d + Au hadron correlation measurements at PHENIX

    Energy Technology Data Exchange (ETDEWEB)

    Sickles, Anne M., E-mail:


    In these proceedings, we discuss recent results from d + Au collisions in PHENIX ridge related measurements and their possible hydrodynamic origin. We present the v{sub 2} at midrapidity and measurements of the pseudorapidity dependence of the ridge, distinguishing between the d-going and Au-going directions. We investigate the possible geometrical origin by comparing v{sub 2} in d + Au to that in p + Pb, Au + Au and Pb + Pb collisions. Future plans to clarify the role of geometry in small collision systems at RHIC are discussed.

  1. Designing a Mathematics Curriculum

    Directory of Open Access Journals (Sweden)

    Lee Peng Yee


    Full Text Available A decade of PMRI saw the changes in the classroom in some of the primary schools in Indonesia. Based on observation, we can say that though the mathematics syllabus in Indonesia did not change, its curriculum has changed under the movement of PMRI. In this article, we put in writing some of the experience gained through the involvement in designing curricula since 1971. Hopefully, some of the observations made may be of use to the colleagues in Indonesia. The discussion below will cover some deciding factors in designing a curriculum, some practices, and the latest trends. For convenience, we keep the discussion general, and do not refer to a specific syllabus. Also, in many cases, we refer mainly to secondary schools, that is, Grade 7 to Grade 10.

    language for adults. The research results indicate that teachers seem to compensate by trying to create virtual communities of learning. Learners, however, experience disembedded relations. Conversely, curriculum development, on tends to ‘exploit’ the conditions of disembedding social relations in e-learning......The outstanding British sociologist Anthony Giddens predicted e-learning environments by describing “modernity”. Giddens emphasised that modernity is inherently globalising, it creates ‘disembedded’ social relations and “tears space away from place by fostering relations between ‘absent’ others......, locationally distant”. The aim of the paper is to analyse and discuss how different positions in e-learning settings result in different answers to modernity. These settings can be applied to either teacher, learner or curriculum positions. The research was based on a qualitative longitudinal case study...

  3. Decay spectroscopy of $^{178}$Au

    CERN Document Server

    Whitmore, B

    In this thesis, the neutron-deficient nucleus $^{178}$Au is investigated through decay spectroscopy. Si and HPGe detectors were used to analyse the decay radiation of $^{178}$Au and its daughter nuclei. Previous studies have been unable to distinguish decay radiation from different isomeric states of this nucleus. This thesis represents the first time such isomeric discrimination has been achieved, and presents tentative spin assignments of both the ground state and an isomer. The neutron-deficient gold isotopes are an area of interest for the study of shape coexistence. This is the phenomenon exhibited by nuclei able to exist at a number of close lying energy minima, each reflecting a distinct type of deformation. It is hoped that studies such as this can help identify the evolution of nuclear deformation in this region of the nuclear chart.

  9. Fabricating a Homogeneously Alloyed AuAg Shell on Au Nanorods to Achieve Strong, Stable, and Tunable Surface Plasmon Resonances

    KAUST Repository

    Huang, Jianfeng


    Colloidal metal nanocrystals with strong, stable, and tunable localized surface plasmon resonances (SPRs) can be useful in a corrosive environment for many applications including field-enhanced spectroscopies, plasmon-mediated catalysis, etc. Here, a new synthetic strategy is reported that enables the epitaxial growth of a homogeneously alloyed AuAg shell on Au nanorod seeds, circumventing the phase segregation of Au and Ag encountered in conventional synthesis. The resulting core–shell structured bimetallic nanorods (AuNR@AuAg) have well-mixed Au and Ag atoms in their shell without discernible domains. This degree of mixing allows AuNR@AuAg to combine the high stability of Au with the superior plasmonic activity of Ag, thus outperforming seemingly similar nanostructures with monometallic shells (e.g., Ag-coated Au NRs (AuNR@Ag) and Au-coated Au NRs (AuNR@Au)). AuNR@AuAg is comparable to AuNR@Ag in plasmonic activity, but that it is markedly more stable toward oxidative treatment. Specifically, AuNR@AuAg and AuNR@Ag exhibit similarly strong signals in surface-enhanced Raman spectroscopy that are some 30-fold higher than that of AuNR@Au. When incubated with a H2O2 solution (0.5 m), the plasmonic activity of AuNR@Ag immediately and severely decayed, whereas AuNR@AuAg retained its activity intact. Moreover, the longitudinal SPR frequency of AuNR@AuAg can be tuned throughout the red wavelengths (≈620–690 nm) by controlling the thickness of the AuAg alloy shell. The synthetic strategy is versatile to fabricate AuAg alloyed shells on different shaped Au, with prospects for new possibilities in the synthesis and application of plasmonic nanocrystals.

    We have used scanning and transmission electron microscopes (SEM and TEM) to study the structure of a pentacene thin film grown on a Au layer with and shown that it consists of randomly oriented amorphous pentacene clusters. We have also investigated the transport properties of amorphous pentacene in a metal–semiconductor–metal (MSM) diode structure and shown that the current is logarithmically proportional to the square root of the applied voltage, which indicates that transport occurs as the result of hopping between localized sites randomly distributed in space and energy.

  14. High-p(T) Tomography of d+Au and Au+Au at SPS, RHIC, and LHC. (United States)

    Vitev, Ivan; Gyulassy, Miklos


    The interplay of nuclear effects on the p(T)>2 GeV inclusive hadron spectra in d+Au and Au+Au reactions at sqrt[s(NN)]=17, 200, and 5500 GeV is compared to leading order perturbative QCD calculations for elementary p+p (p+p) collisions. The competition between nuclear shadowing, Cronin effect, and jet energy loss due to medium-induced gluon radiation is predicted to lead to a striking energy dependence of the nuclear suppression/enhancement pattern in A+A reactions. We show that future d+Au data can be used to disentangle the initial and final state effects.

    Full Text Available PHENIX measurements of high transverse momentum (pT identified hadrons in d+Au and Au+Au collisions are presented. The nuclear modification factors (RdA and RAA for π0 and ƞ are found to be very consistent in both collision systems, respectively. Using large amount of p + p and Au+Au datasets, the fractional momentum loss (Sloss and the path-length dependent yield of π0 in Au+Au collisions are obtained. The hadron spectra in the most central d+Au and the most peripheral Au+Au collisions are studied. The spectra shapes are found to be similar in both systems, but the yield is suppressed in the most peripheral Au+Au collisions.

  16. Au38(SPh)24: Au38 Protected with Aromatic Thiolate Ligands. (United States)

    Rambukwella, Milan; Burrage, Shayna; Neubrander, Marie; Baseggio, Oscar; Aprà, Edoardo; Stener, Mauro; Fortunelli, Alessandro; Dass, Amala


    Au38(SR)24 is one of the most extensively investigated gold nanomolecules along with Au25(SR)18 and Au144(SR)60. However, so far it has only been prepared using aliphatic-like ligands, where R = -SC6H13, -SC12H25 and -SCH2CH2Ph. Au38(SCH2CH2Ph)24 when reacted with HSPh undergoes core-size conversion to Au36(SPh)24, and existing literature suggests that Au38(SPh)24 cannot be synthesized. Here, contrary to prevailing knowledge, we demonstrate that Au38(SPh)24 can be prepared if the ligand exchanged conditions are optimized, under delicate conditions, without any formation of Au36(SPh)24. Conclusive evidence is presented in the form of matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS), electrospray ionization mass spectra (ESI-MS) characterization, and optical spectra of Au38(SPh)24 in a solid glass form showing distinct differences from that of Au38(S-aliphatic)24. Theoretical analysis confirms experimental assignment of the optical spectrum and shows that the stability of Au38(SPh)24 is not negligible with respect to that of its aliphatic analogous, and contains a significant component of ligand-ligand attractive interactions. Thus, while Au38(SPh)24 is stable at RT, it converts to Au36(SPh)24 either on prolonged etching (longer than 2 hours) at RT or when etched at 80 °C.

  17. Sustainability Infused Curriculum (United States)

    Ibarra, D. L.


    The Independent Schools Foundation Academy (ISF) in Hong Kong established a sustainability policy in 2015, which explicitly states, "an experimentally integrated, environmentally and ethically sustainable system of science education and conservation practices based on the 2012 Jeju Declaration of the World Conservation Congress will be implemented through the school". ISF Academy is a private Chinese bilingual school in Hong Kong serving over 1500 students K-12, following the framework and curriculum of the International Baccalaureate Organization (IBO). The strategy behind the implementation of this policy includes: development of a scientific sustainable curriculum that is age appropriate; establish a culture of sustainability within the ISF community and beyond to the wider HK community; install sustainable infrastructure that allows students to learn; and learn first hand sustainable living practices. It is well understood that solutions to the environmental challenges facing Hong Kong and our planet will require multiple disciplines. The current sustainability programs at ISF include: a) a whole school aerobic food waste composting system and organic farming, b) energy consumption monitoring of existing buildings, c) upcoming installation of an air pollution monitoring equipment that will correlate with the AQHI data collected by the Hong Kong government, d) a Renewable Energy Education Center (REEC) that will teach students about RE and also produce solar energy for classroom consumption, and e) student lead environmental group that manages the paper and used cooking oil recycling on campus. The Shuyuan Science and Sustainability faculty work closely with classroom teachers to ensure that the above mentioned projects are incorporated into the curriculum throughout the school. Interdisciplinary units (IDU) of study are being developed that encourage faculty and students to work across subject areas. Projects include Personal Projects, Extended Essays

  1. Integrated Curriculum and Subject-based Curriculum: Achievement and Attitudes (United States)

    Casady, Victoria

    The research conducted for this mixed-method study, qualitative and quantitative, analyzed the results of an academic year-long study to determine whether the use of an integrated fourth grade curriculum would benefit student achievement in the areas of English language arts, social studies, and science more than a subject-based traditional curriculum. The research was conducted based on the international, national, and state test scores, which show a slowing or lack of growth. Through pre- and post-assessments, student questionnaires, and administrative interviews, the researcher analyzed the phenomenological experiences of the students to determine if the integrated curriculum was a beneficial restructuring of the curriculum. The research questions for this study focused on the achievement and attitudes of the students in the study and whether the curriculum they were taught impacted their achievement and attitudes over the course of one school year. The curricula for the study were organized to cover the current standards, where the integrated curriculum focused on connections between subject areas to help students make connections to what they are learning and the world beyond the classroom. The findings of this study indicated that utilizing the integrated curriculum could increase achievement as well as students' attitudes toward specific content areas. The ANOVA analysis for English language arts was not determined to be significant; although, greater growth in the students from the integrated curriculum setting was recorded. The ANOVA for social studies (0.05) and the paired t-tests (0.001) for science both determined significant positive differences. The qualitative analysis led to the discovery that the experiences of the students from the integrated curriculum setting were more positive. The evaluation of the data from this study led the researcher to determine that the integrated curriculum was a worthwhile endeavor to increase achievement and attitudes

  19. Curriculum theory in physical education (United States)

    Jewett, Ann E.


    Primary current concerns of curriculum theorists in sport and physical education relate to clarification of value orientations underlying curricular decision-making, selection and statement of curriculum goals, identification and organization of programme content, and the process of curriculum change. Disciplinary mastery is the most traditional value orientation and that which is most frequently found in practice. Curriculum theorists have identified four other value orientations for study: social reconstruction, self-actualization, learning process, and ecological validity. Health-related fitness and the development of motor skills have long been the primary goals of physical education. In recent years, however, curriculum specialists have begun to assign higher priorities to goals of personal integration and challenge, of social development and multicultural understanding. There is general agreement that human movement activities constitute the subject-matter of the sport and physical education curriculum. Differences exist, however, as to how learning activities should be selected for particular programmes. The current trend in seeking better understanding of content is toward studying the operational curriculum with particular attention to the historical and social contexts. An important contemporary focus is the need to translate short-term results into lifestyle changes. The curriculum in sports and physical education should be viewed as a multitude of possibilities.

  7. PHENIX results on collectivity in high-multiplicity p + Au, d + Au and 3He + Au collisions (United States)

    Xu, Qiao


    We present recent PHENIX results for long-range two-particle correlation functions across a large pseudorapidity(η) gap in high-multiplicity p+Au, d+Au and 3He+Au collisions. Enhanced correlations are observed for particles with small azimuthal separation. Measurements of the second order Fourier coefficients (v 2) in p/d/3He+Au collisions, and the third order Fourier coefficient (v 3) in 3He+Au collision are performed using the event plane method. Scaling of v 2 with the initial eccentricity (ɛ 2) is performed in each system to investigate the role of the initial geometry in the development of a final-state anisotropy in the particle emission. The v 2 coefficients for identified π±, K± and (anti-)proton are measured as a function of transverse kinetic energy (KET) and their magnitudes are found to scale approximately with the number of constituent quarks in the hadron.

  8. Comparative study of anchoring groups for molecular electronics: structure and conductance of Au-S-Au and Au-NH{sub 2}-Au junctions

    The electrical properties of single-molecule junctions, consisting of an organic molecule coupled to metal electrodes, are sensitive to the detailed atomic structure of the molecule-metal contact. This, in turn, is determined by the anchoring group linking the molecule to the metal. With the aim of identifying and comparing the intrinsic properties of two commonly used anchoring groups, namely thiol and amine groups, we have calculated the atomic structure and conductance traces of different Au-S-Au and Au-NH{sub 2}-Au nanojunctions using density functional theory (DFT). Whereas NH{sub 2} shows a strong structural selectivity towards atop-gold configurations, S shows large variability in its bonding geometries. As a result, the conductance of the Au-NH{sub 2}-Au junction is less sensitive to the structure of the gold contacts than the Au-S-Au junction. These findings support recent experiments which show that amine-bonded molecules exhibit more well-defined conductance properties than do thiol-bonded molecules.

  11. Au microstructure and the functional properties of Ni/Au finishes on ceramic IC packages

    Energy Technology Data Exchange (ETDEWEB)

    Winters, E.D.; Baxter, W.K. [Coors Electronic Package Co., Chattanooga, TN (United States); Braski, D.N.; Watkins, T.R. [Oak Ridge National Lab., TN (United States)


    Ni/Au plated finishes used on thick-film metallized multilayer ceramic packages for integrated circuits must meet functional requirements such as bondability, sealability, and solderability. Their ability to do so is dependent, among other things, on the ability of the Au deposit to inhibit the grain boundary diffusion and subsequent surface oxidation of Ni. In this study, the relation between functional performance, Ni diffusionr ate, and Au microstructure was examined. Extent of Ni diffusion during heating was determined by Auger electron spectroscopy for several electrolytic and electroless Ni/Au finishing processes. Results were correlated with differences in Au microstructures determined by SEM, atomic force microscopy, and XRD.

  16. Structure of the thiolated Au130 cluster. (United States)

    The structure of the recently discovered Au130-thiolate and -dithiolate clusters is explored in a combined experiment-theory approach. Rapid electron diffraction in scanning/transmission electron microscopy (STEM) enables atomic-resolution imaging of the gold core and the comparison with density functional theory (DFT)-optimized realistic structure models. The results are consistent with a 105-atom truncated-decahedral core protected by 25 short staple motifs, incorporating disulfide bridges linking the dithiolate ligands. The optimized structure also accounts, via time-dependent DFT (TD-DFT) simulation, for the distinctive optical absorption spectrum, and rationalizes the special stability underlying the selective formation of the Au130 cluster in high yield. The structure is distinct from, yet shares some features with, each of the known Au102 and Au144/Au146 systems.

  17. Gas-phase experiments on Au(III) photochemistry. (United States)

    Marcum, Jesse C; Kaufman, Sydney H; Weber, J Mathias


    Irradiation of AuCl(4)(-) and AuCl(2)(OH)(2)(-) in the gas-phase using ultraviolet light (220-415 nm) leads to their dissociation. Observed fragment ions for AuCl(4)(-) are AuCl(3)(-) and AuCl(2)(-) and for AuCl(2)(OH)(2)(-) are AuCl(2)(-) and AuClOH(-). All fragment channels correspond to photoreduction of the gold atom to either Au(II) or Au(I) depending on the number of neutral ligands lost. Fragment branching ratios of AuCl(4)(-) are observed to be highly energy dependent and can be explained by comparison of the experimental data to calculated threshold energies obtained using density functional theory. The main observed spectral features are attributed to ligand-to-metal charge transfer transitions. These results are discussed in the context of the molecular-level mechanisms of Au(III) photochemistry.

    Full Text Available "The paper focuses on the relations between two 16th century works: Marcellus Palingenius’ The Zodiac of Life and Mikołaj Rej’s The Image of a Good Man’s Life. The philosophical poem Zodiacus vitae fell into oblivion in Italy, but has gained considerable popularity all over Europe since the 16th century. In Poland all the greatest Renaissance humanists, such as Jan Kochanowski and Mikołaj Rej, knew and read it. The latter, clearly inspired by the work of the Italian master, published The Image of a Good Man’s Life in 1558. Since the 19th century there have been some comparative studies of The Zodiac and The Image in the field of Polish literature. This article presents the current state of the research and points out general similarities and differences between these works, regarding both the story line and philosophy. "

    do Nascimento, Juliana Luporini; Nunes, Everardo Duarte


    Among the various ways of adopting the biographical approach, we used the curriculum vitaes (CVs) of Brazilian researchers who work as social scientists in health as our research material. These CVs are part of the Lattes Platform of CNPq - the National Council for Scientific and Technological Development, which includes Research and Institutional Directories. We analyzed 238 CVs for this study. The CVs contain, among other things, the following information: professional qualifications, activities and projects, academic production, participation in panels for the evaluation of theses and dissertations, research centers and laboratories and a summarized autobiography. In this work there is a brief review of the importance of autobiography for the social sciences, emphasizing the CV as a form of "autobiographical practice." We highlight some results, such as it being a group consisting predominantly of women, graduates in social sciences, anthropology, sociology or political science, with postgraduate degrees. The highest concentration of social scientists is located in Brazil's southern and southeastern regions. In some institutions the main activities of social scientists are as teachers and researchers with great thematic diversity in research.

  7. Global curriculum in surgical oncology. (United States)

    Are, C; Berman, R S; Wyld, L; Cummings, C; Lecoq, C; Audisio, R A


    The significant global variations in surgical oncology training paradigms can have a detrimental effect on tackling the rising global cancer burden. While some variations in training are essential to account for the differences in types of cancer and biology, the fundamental principles of providing care to a cancer patient remain the same. The development of a global curriculum in surgical oncology with incorporated essential standards could be very useful in building an adequately trained surgical oncology workforce, which in turn could help in tackling the rising global cancer burden. The leaders of the Society of Surgical Oncology and European Society of Surgical Oncology convened a global curriculum committee to develop a global curriculum in surgical oncology. A global curriculum in surgical oncology was developed to incorporate the required domains considered to be essential in training a surgical oncologist. The curriculum was constructed in a modular fashion to permit flexibility to suit the needs of the different regions of the world. Similarly, recognizing the various sociocultural, financial and cultural influences across the world, the proposed curriculum is aspirational and not mandatory in intent. A global curriculum was developed which may be considered as a foundational scaffolding for training surgical oncologists worldwide. It is envisioned that this initial global curriculum will provide a flexible and modular scaffolding that can be tailored by individual countries or regions to train surgical oncologists in a way that is appropriate for practice in their local environment.

    Highlights: > 3-Mercaptopropionic acid (MPA) or meso-2,3-dimercaptosuccinic acid (DMSA) mediated Au corrosion in aqueous electrolytes at anodic potentials. > Au is roughened and passivated by an insoluble Au-MPA product. > Au is leached into the aqueous electrolyte as a soluble Au-DMSA species ({approx}60 ppb, 12 h). - Abstract: The electrochemical characteristics of polycrystalline Au in LiClO{sub 4} electrolyte solutions containing 3-mercaptopropionic acid (MPA) or meso-2,3-dimercaptosuccinic acid (DMSA) were studied with linear sweep voltammetry (LSV) and electrochemical impedance spectroscopy (EIS) over a wide range of positive potentials vs. Ag/AgCl. The EIS data exhibited linear capacitive behaviour at 0.0 V with either MPA or DMSA added directly to the electrolyte suggesting the formation of an adsorbed layer of the alkylthiol on the electrode surface. Above this potential, a single well-defined impedance loop appeared for electrolyte solutions containing DMSA or MPA, an observation indicative of a charge transfer reaction that could be related to several processes including oxidative desorption, oxidation of the alkylthiol, or Au oxidation/dissolution. To test for Au dissolution, the electrode was held at 0.8 V vs. Ag/AgCl for 12 h in electrolytes containing MPA or DMSA followed by surface analysis with Atomic Force Microscopy and solution analysis with Atomic Absorption Spectroscopy. When the electrolyte contained MPA, the extended potential holding procedure resulted in significant roughening of the electrode with no detectable quantities of Au in the electrolyte. X-ray photoelectron spectroscopy (XPS) analysis of the Au surface revealed an additional species in the Au 4f{sub 7/2} spectrum indicating the presence of an insoluble electrochemically generated Au(I)-MPA species. When the electrolyte contained DMSA, the Au electrode appeared smoother, 56.6 {+-} 9.6 ppb of Au was detected in the electrolyte and the XPS analysis displayed a single species in the

  9. Au/Au@polythiophene core/shell nanospheres for heterogeneous catalysis of nitroarenes. (United States)

    Shin, Hye-Seon; Huh, Seong


    Monodisperse Au/Au@polythiophene core/shell nanospheres were facilely prepared through the reduction of gold precursor, AuCl₄⁻, by 2-thiopheneacetonitrile in an aqueous solution. Concomitantly, 2-thiopheneacetonitrile polymerized during this redox process. As a result, Au nanoparticle was encapsulated by conductive polymer shell to afford novel core/shell nanospheres. Interestingly, the shell was composed of very tiny Au nanoparticles surrounded with thiophene polymers. Thus, the new material is best described as Au/Au@polythiophene core/shell nanospheres. FT-IR spectroscopy revealed that the Au nanoparticles were coordinated by the C≡N groups of the polythiophene shell. Some of the C≡N groups were partially hydrolyzed into COOH groups during the redox process because of the acidic reaction condition. The shell was conductive based on the typical ohmic behavior found in electrical measurement. The Au/Au@polythiophene core/shell nanospheres were found to be very active catalysts for the hydrogenation of various nitroarene compounds into corresponding aminoarene compounds in the presence of NaBH₄. Both hydrophilic and hydrophobic nitroarenes were efficiently hydrogenated under mild conditions.

  10. Development of an EMS curriculum. (United States)

    Brice, Jane H; Perina, Debra G; Liu, J Marc; Braude, Darren A; Rinnert, Kathy J; MacDonald, Russell D


    Emergency medical services (EMS) became an American Board of Medical Specialties (ABMS) approved subspecialty of emergency medicine in September 2010. Achieving specialty or subspecialty recognition in an area of medical practice requires a unique body of knowledge, a scientific basis for the practice, a significant number of physicians who dedicate a portion of their practice to the area, and a sufficient number of fellowship programs. To prepare EMS fellows for successful completion of fellowship training, a lifetime of subspecialty practice, and certification examination, a formalized structured fellowship curriculum is necessary. A functional curriculum is one that takes the entire body of knowledge necessary to appropriately practice in the identified area and codifies it into a training blueprint to ensure that all of the items are covered over the prescribed training period. A curriculum can be as detailed as desired but typically all major headings and subheadings of the core content are identified and addressed. Common curricular components, specific to each area of the core content, include goals and objectives, implementation methods, evaluation, and outcomes assessment methods. Implementation methods can include simulation, observations, didactics, and experiential elements. Evaluation and outcomes assessment methods can include direct observation of patient assessment and treatment skills, structured patient simulations, 360° feedback, written and oral testing, and retrospective chart reviews. This paper describes a curriculum that is congruent with the current EMS core content, as well as providing a 12-month format to deploy the curriculum in an EMS fellowship program. Key words: curriculum; education; emergency medical services; fellowships and scholarships.

  13. Synthesis of ultrathin face-centered-cubic Au@Pt and Au@Pd core-shell nanoplates from hexagonal-close-packed Au square sheets

    KAUST Repository

    Fan, Zhanxi


    The synthesis of ultrathin face-centered-cubic (fcc) Au@Pt rhombic nanoplates is reported through the epitaxial growth of Pt on hexagonal-close-packed (hcp) Au square sheets (AuSSs). The Pt-layer growth results in a hcp-to-fcc phase transformation of the AuSSs under ambient conditions. Interestingly, the obtained fcc Au@Pt rhombic nanoplates demonstrate a unique (101)f orientation with the same atomic arrangement extending from the Au core to the Pt shell. Importantly, this method can be extended to the epitaxial growth of Pd on hcp AuSSs, resulting in the unprecedented formation of fcc Au@Pd rhombic nanoplates with (101)f orientation. Additionally, a small amount of fcc (100)f-oriented Au@Pt and Au@Pd square nanoplates are obtained with the Au@Pt and Au@Pd rhombic nanoplates, respectively. We believe that these findings will shed new light on the synthesis of novel noble bimetallic nanostructures. Phase change: Ultrathin Au@Pt and Au@Pd core-shell nanoplates were prepared from Au square sheets. A phase transformation from hexagonal close-packed (hcp) to face-centered cubic (fcc) is observed upon coating the hcp Au square sheets with Pt or Pd under ambient conditions. The prepared fcc Au@Pt and Au@Pd rhombic nanoplates demonstrate unique (101)f orientation (picture shows a typical fcc Au@Pt rhombic nanoplate). © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

  14. Knowledge and curriculum

    Directory of Open Access Journals (Sweden)

    Šaranović-Božanović Nadežda


    Full Text Available The paper raises the questions as follows: What is knowledge in general? What is it that a student should know? What does it mean that somebody knows something? Those questions point to a volume of dilemmas related to the epistemological issue of the nature of knowledge. Regardless of some authors' views that knowledge has not been defined yet, in the present paper knowledge is a subject matter of analysis from the aspect of various theoretical conceptions. The fact is that curricula development as well as the conception of student cognitive development depends on how knowledge is defined. Also, a question is raised on how beliefs about human thinking affect curricula development and accomplishment. It is all the more important if the basic function of education is considered to be knowledge acquisition and development of intellectual abilities. Regarding different approaches to curriculum development, the paper points to some epistemological postulates that affected educational practice. It is true that a model of talking and numerical approach dominate educational practice. It would be quite appropriate to modify curricula in accordance with contemporary theoretical-empirical research results. There is a general agreement that the process of knowledge acquisition in teaching should become the subject of special analysis in order that its regularities can be understood.

  16. Comparative efficiencies of photothermal destruction of malignant cells using antibody-coated silica-Au nanoshells, hollow Au/Ag nanospheres and Au nanorods

    Energy Technology Data Exchange (ETDEWEB)

    Cheng, Fong-Yu; Chen, Chen-Tai; Yeh, Chen-Sheng, E-mail: [Department of Chemistry, National Cheng Kung University, Tainan 701, Taiwan (China)


    Three Au-based nanomaterials (silica-Au nanoshells, hollow Au/Ag nanospheres and Au nanorods) were evaluated for their comparative photothermal efficiencies at killing three types of malignant cells (A549 lung cancer cells, HeLa cervix cancer cells and TCC bladder cancer cells) using a CW NIR laser. Photodestructive efficiency was evaluated as a function of the number of nanoparticles required to destroy the cancer cells under 808 nm laser wavelength at fixed laser power. Of the three nanomaterials, silica/Au nanoshells needed the minimum number of particles to produce effective photodestruction, whereas Au nanorods needed the largest number of particles. Together with the calculated photothermal conversion efficiency, the photothermal efficiency rankings are silica-Au nanoshells > hollow Au/Ag nanospheres > Au nanorods. Additionally, we found that HeLa cells seem to present better heat tolerance than the other two cancer cell lines.

    Filip, Peter; Lednicky, Richard; Masui, Hiroshi; Xu, Nu


    Initial eccentricity and eccentricity fluctuations of the interaction volume created in relativistic collisions of deformed {sup 197}Au and {sup 238}U nuclei are studied using optical and Monte-Carlo (MC) Glauber simulations. It is found that the non-sphericity noticeably influences the average eccentricity in central collisions and eccentricity fluctuations are enhanced due to deformation. Quantitative results are obtained for Au+Au and U+U collisions at energy {radical}s{sub NN} = 200 GeV.

  18. Photovoltage responses of graphene-Au heterojunctions (United States)

    Li, Kai; Ying, Xiangxiao; Wang, Juan; Wang, Jun; Jiang, Yadong; Liu, Zhijun


    As an emerging 2D material, graphene's several unique properties, such as high electron mobility, zero-bandgap and low density of states, present new opportunities for light detections. Here, we report on photovoltage responses of graphene-Au heterojunctions, which are made of monolayer graphene sheets atop Au electrodes designed as finger-shape and rectangle-shape, respectively. Besides confirming the critical role of space charge regions located at the graphene-Au boundary, photovoltage responses are measured in the visible to infrared spectral region with a cut-off wavelength at about 980 nm, which is likely imposed by the Pauli blocking of interband transition in the contact-doped graphene. The photoresponsivity is shown to decrease with increasing wavelength. A band diagram of the graphene-Au heterojunction is proposed to understand the photoresponse mechanism.

    Yu, Chongqi; Harbich, Wolfgang; Sementa, Luca; Ghiringhelli, Luca; Apra, Edoardo; Stener, Mauro; Fortunelli, Alessandro; Brune, Harald


    Ligand-protected Au clusters are non-bleaching fluorescence markers in bio- and medical applications. We show that their fluorescence is an intrinsic property of the Au cluster itself. We find a very intense and sharp fluorescence peak located at λ =739.2 nm (1.68 eV) for Au20 clusters in a Ne matrix held at 6 K. The fluorescence reflects the HOMO-LUMO diabatic bandgap of the cluster. The cluster shows a very rich absorption fine structure reminiscent of well defined molecule-like quantum levels. These levels are resolved since Au20 has only one stable isomer (tetrahedral), therefore our sample is mono-disperse in cluster size and conformation. Density-functional theory (DFT) and time-dependent DFT calculations clarify the nature of optical absorptionand predict both main absorption peaks and intrinsic fluorescence in good agreement with experiment.

  20. PHENIX results on jets in d + Au (United States)

    Hanks, J. Ali


    We present recently published results [A. Adare, et al., arxiv:arXiv:1509.04657] on fully reconstructed R=0.3 anti-kt jets measured in p+p and d+Au collisions at 200 GeV center-of-mass energy. The jet yields for four centrality classes along with the p+p reference are presented, as well as both the minimum bias RdAu and centrality dependent RdAu and RCP. We find that while the minimum bias RdA is consistent with unity, providing a strong constraint on models including cold-nuclear-matter effects or energy loss in small systems, the centrality dependent RdAu show a striking variation which presents a challenge to models attempting to describe the interplay between soft and hard processes in these systems.

  2. Unravelling Thiol’s Role in Directing Asymmetric Growth of Au Nanorod–Au Nanoparticle Dimers

    KAUST Repository

    Huang, Jianfeng


    Asymmetric nanocrystals have practical significance in nanotechnologies but present fundamental synthetic challenges. Thiol ligands have proven effective in breaking the symmetric growth of metallic nanocrystals but their exact roles in the synthesis remain elusive. Here, we synthesized an unprecedented Au nanorod-Au nanoparticle (AuNR-AuNP) dimer structure with the assistance of a thiol ligand. On the basis of our experimental observations, we unraveled for the first time that the thiol could cause an inhomogeneous distribution of surface strains on the seed crystals as well as a modulated reduction rate of metal precursors, which jointly induced the asymmetric growth of monometallic dimers. © 2015 American Chemical Society.

  4. Enantioselective separation on chiral Au nanoparticles. (United States)

    Shukla, Nisha; Bartel, Melissa A; Gellman, Andrew J


    The surfaces of chemically synthesized Au nanoparticles have been modified with d- or l-cysteine to render them chiral and enantioselective for adsorption of chiral molecules. Their enantioselective interaction with chiral compounds has been probed by optical rotation measurements during exposure to enantiomerically pure and racemic propylene oxide. The ability of optical rotation to detect enantiospecific adsorption arises from the fact that the specific rotation of polarized light by (R)- and (S)-propylene oxide is enhanced by interaction with Au nanoparticles. This effect is related to previous observations of enhanced circular dichroism by Au nanoparticles modified by chiral adsorbates. More importantly, chiral Au nanoparticles modified with either d- or l-cysteine selectively adsorb one enantiomer of propylene oxide from a solution of racemic propylene oxide, thus leaving an enantiomeric excess in the solution phase. Au nanoparticles modified with l-cysteine (d-cysteine) selectively adsorb the (R)-propylene oxide ((S)-propylene oxide). A simple model has been developed that allows extraction of the enantiospecific equilibrium constants for (R)- and (S)-propylene oxide adsorption on the chiral Au nanoparticles.

  6. Systematic Measurements of Identified Particle Spectra in pp, d+Au and Au+Au Collisions from STAR

    Energy Technology Data Exchange (ETDEWEB)

    STAR Coll


    Identified charged particle spectra of {pi}{sup {+-}}, K{sup {+-}}, p and {bar p} at mid-rapidity (|y| < 0.1) measured by the dE/dx method in the STAR-TPC are reported for pp and d + Au collisions at {radical}s{sub NN} = 200 GeV and for Au + Au collisions at 62.4 GeV, 130 GeV, and 200 GeV. Average transverse momenta, total particle production, particle yield ratios, strangeness and baryon production rates are investigated as a function of the collision system and centrality. The transverse momentum spectra are found to be flatter for heavy particles than for light particles in all collision systems; the effect is more prominent for more central collisions. The extracted average transverse momentum of each particle species follows a trend determined by the total charged particle multiplicity density. The Bjorken energy density estimate is at least several GeV/fm{sub 3} for a formation time less than 1 fm/c. A significantly larger net-baryon density and a stronger increase of the net-baryon density with centrality are found in Au + Au collisions at 62.4 GeV than at the two higher energies. Antibaryon production relative to total particle multiplicity is found to be constant over centrality, but increases with the collision energy. Strangeness production relative to total particle multiplicity is similar at the three measured RHIC energies. Relative strangeness production increases quickly with centrality in peripheral Au + Au collisions, to a value about 50% above the pp value, and remains rather constant in more central collisions. Bulk freeze-out properties are extracted from thermal equilibrium model and hydrodynamics-motivated blast-wave model fits to the data. Resonance decays are found to have little effect on the extracted kinetic freeze-out parameters due to the transverse momentum range of our measurements. The extracted chemical freeze-out temperature is constant, independent of collision system or centrality; its value is close to the predicted phase

    We report measurements of ϒ meson production in p+p, d+Au, and Au+Au collisions using the STAR detector at RHIC. We compare the ϒ yield to the measured cross section in p+p collisions in order to quantify any modifications of the yield in cold nuclear matter using d+Au data and in hot nuclear matter using Au+Au data separated into three centrality classes. Our p+p measurement is based on three times the statistics of our previous result. We obtain a nuclear modification factor for ϒ(1S+2S+3S) in the rapidity range |y|<1 in d+Au collisions of R{sub dAu}=0.79±0.24(stat.)±0.03(syst.)±0.10(p+p syst.). A comparison with models including shadowing and initial state parton energy loss indicates the presence of additional cold-nuclear matter suppression. Similarly, in the top 10% most-central Au+Au collisions, we measure a nuclear modification factor of R{sub AA}=0.49±0.1(stat.)±0.02(syst.)±0.06(p+psyst.), which is a larger suppression factor than that seen in cold nuclear matter. Our results are consistent with complete suppression of excited-state ϒ mesons in Au+Au collisions. The additional suppression in Au+Au is consistent with the level expected in model calculations that include the presence of a hot, deconfined Quark–Gluon Plasma. However, understanding the suppression seen in d+Au is still needed before any definitive statements about the nature of the suppression in Au+Au can be made.

    The proton beam intensity of a 100-MeV proton linac at the Korea Multi-purpose Accelerator Complex (KOMAC) was measured by an Au activation analysis using {sup 197}Au(p, pn){sup 196}Au and {sup 197}Au(p, p3n){sup 194}Au reactions to determine the accuracy and precision of beam intensity measurement using Gafchromic film dosimetry method. The target, irradiated by 100-MeV protons, was arranged in a stack consisting of Au, Al foils and Pb plates. The yields of produced radio-nuclei in Au foils were obtained by gamma-ray spectroscopy. The FLUKA code was employed to calculate the energy spectrum of protons onto the front surface of Au foils located at three different depth points of the target and also to investigate the condition of incident beam on the target. A good agreement was found between the beam intensity measurements using the activation analysis method at three different depth points of the target. An excellent agreement was also observed between the beam intensity measurements using the Au activation analysis method and the dosimetry method using Gafchromic film.

  11. Toward hybrid Au nanorods @ M (Au, Ag, Pd and Pt) core-shell heterostructures for ultrasensitive SERS probes (United States)

    Xie, Xiaobin; Gao, Guanhui; Kang, Shendong; Lei, Yanhua; Pan, Zhengyin; Shibayama, Tamaki; Cai, Lintao


    Being able to precisely control the morphologies of noble metallic nanostructures is of essential significance for promoting the surface-enhanced Raman scattering (SERS) effect. Herein, we demonstrate an overgrowth strategy for synthesizing Au @ M (M = Au, Ag, Pd, Pt) core-shell heterogeneous nanocrystals with an orientated structural evolution and highly improved properties by using Au nanorods as seeds. With the same reaction condition system applied, we obtain four well-designed heterostructures with diverse shapes, including Au concave nanocuboids (Au CNs), Au @ Ag crystalizing face central cube nanopeanuts, Au @ Pd porous nanocuboids and Au @ Pt nanotrepangs. Subsequently, the exact overgrowth mechanism of the above heterostructural building blocks is further analysed via the systematic optimiziation of a series of fabrications. Remarkably, the well-defined Au CNs and Au @ Ag nanopeanuts both exhibit highly promoted SERS activity. We expect to be able to supply a facile strategy for the fabrication of multimetallic heterogeneous nanostructures, exploring the high SERS effect and catalytic activities.

    Neutral pions have been measured in 3He+Au collisions at √{sNN } = 200 GeV up to 20 GeV/c in the RHIC Year-2014 run. The nuclear modification factor RAA was measured and compared with that from d+Au collisions. The integrated RAA as a function of Npart was calculated for d+Au, 3He+Au and Au+Au collisions at √{sNN } = 200 GeV, and found to converge for Npart > 12, while a clear system ordering RdAu >RHeAu >RAuAu was observed for Npart > 12. The fractional momentum loss for the most central 3He+Au collisions was also estimated.

  14. Collaboration leads to enhanced curriculum. (United States)

    Valerius, J; Mohan, V; Doctor, D; Hersh, W


    In 2007, we initiated a health information management (HIM) track of our biomedical informatics graduate program, and subsequent ongoing program assessment revealed a confluence of topics and courses within HIM and clinical informatics (CI) tracks. We completed a thorough comparative analysis of competencies derived from AMIA, AHIMA, and CAHIIM. Coupled with the need to streamline course offerings, the process, described in this paper allowed new opportunities for faculty collaboration, resulted in the creation of a model assessment for best practice in courses, and led to new avenues of growth within the program. The objective of the case study is to provide others in the informatics educational community with a model for analysis of curriculum in order to improve quality of student learning. We describe a case study where an academic informatics program realigned its course offerings to better reflect the HIM of today, and prepare for challenges of the future. Visionary leadership, intra-departmental self-analysis and alignment of the curriculum through defined mapping process reduced overlap within the CI and HIM tracks. Teaching within courses was optimized through the work of core faculty collaboration. The analysis of curriculum resulted in reduction of overlap within course curriculum. This allowed for additional and new course content to be added to existing courses. Leadership fostered an environment where top-down as well as bottom-up collaborative assessment activities resulted in a model to consolidate learning and reduce unnecessary duplication within courses. A focus on curriculum integration, emphasis on course alignment and strategic consolidation of course content raised the quality of informatics education provided to students. Faculty synergy was an essential component of this redesign process. Continuous quality improvement strategy included an ongoing alignment of curriculum and competencies through a comparative analysis approach. Through

    Reid, Lynette; Macleod, Anna; Byers, David; Delva, Dianne; Fedak, Tim; Mann, Karen; Marrie, Tom; Merritt, Brenda; Simpson, Christy


    Dalhousie University's MD Programme faced a one-year timeline for renewal of its undergraduate curriculum. Key goals were renewed faculty engagement for ongoing quality improvement and increased collaboration across disciplines for an integrated curriculum, with the goal of preparing physicians for practice in the twenty-first century. We engaged approximately 600 faculty members, students, staff and stakeholders external to the faculty of medicine in a process described by Harris (1993) as 'deliberative curriculum inquiry'. Temporally overlapping and networked intraprofessional and interprofessional teams developed programme outcomes, completed environment scans of emerging content and best practices, and designed curricular units. The resulting curriculum is the product of new collaborations among faculty and exemplifies distinct forms of integration. Innovations include content and cases shared by concurrent units, foundations courses at the beginning of each year and integrative experiences at the end, and an interprofessional community health mentors programme. The use of deliberative inquiry for pre-med curriculum renewal on a one-year time frame is feasible, in part through the use of technology. Ongoing structures for integration remain challenging. Although faculty collaboration fosters integration, a learner-centred lens must guide its design.

    In connection to the decision of installing the INDRA detector by the SIS synchrocyclotron at GSI (Darmstadt, Germany) the report presents the tasks taken into account by the LPC-Caen. These refer to the detector displacement and (mechanical) installation at GSI, the tests before beam (i.e. electronics acquisition software, detectors, etc.) as well as the data acquisition and processing. The physical pro-arguments mention the possibility of disposing of heavy ion beams in a range from 50 MeV to several GeV/nucleon so extending the study of multifragmentation done at GANIL between 30 and 90 MeV/nucleon. More specific, the scientific program of INDRA at GSI inserts studies between those done at around Fermi energy, were the reaction mechanisms are of type of deep inelastic scattering/incomplete fusion, and the studies in the relativistic energy domain where the individual properties of nucleons and transparency of nuclear matter implies mechanisms of the participant-spectator type (fire-ball creation). Also mentioned as fields of extensive studies are: the multifragmentation and its fundamental relation with the nuclear matter equation of state, the role of reaction dynamics in the appearance of collective effects of the radial flow type and its relations with the nuclear compressibility and phase transitions and the thermodynamics of nuclear matter. It appeared that the heavy systems Xe + Sn and Au + Au are the best compromise for the different topics to be approached. The bombarding energies extend from 50 to 150 MeV/nucleon. The report ends with the table giving for six heavy systems (Xe + Sn, Au + Au, C + Au, Ar + Au and P + Au) the required bombarding energies 15 refs.

    A key debate in the curriculum field has centred on the extent to which teachers should or could achieve agency over the curriculum they enact. Risks to teacher agency have come from top-down control of curricula, either through input regulation (prescription of content, methods and/or teaching...... materials) or output regulation (steering through outcomes). Drawing upon an ‘ecological model’ to explore the concept of teacher agency, this chapter will illustrate through empirical research conducted in Scotland and Cyprus, how it manifests in various ways through teachers’ work.

    Full Text Available Unschoolers are sometimes regarded as using "no curriculum." This article proposes that curriculum is a path of thought inherent to everyone who thinks. Curriculum is determined not by external sources but by the interaction between the flow of external sources and the actively mediating consciousness of the living learner. This is true whether one is schooling, homeschooling, unschooling or other, because the inner curriculum constantly flows and overcomes obstacles, just as a river finds its way around dam.

  19. The extraction characteristic of Au-Ag from Au concentrate by thiourea solution (United States)

    Kim, Bongju; Cho, Kanghee; On, Hyunsung; Choi, Nagchoul; Park, Cheonyoung


    The cyanidation process has been used commercially for the past 100 years, there are ores that are not amenable to treatment by cyanide. Interest in alternative lixiviants, such as thiourea, halogens, thiosulfate and malononitrile, has been revived as a result of a major increase in gold price, which has stimulated new developments in extraction technology, combined with environmental concern. The Au extraction process using the thiourea solvent has many advantages over the cyanidation process, including higher leaching rates, faster extraction time and less than toxicity. The purpose of this study was investigated to the extraction characteristic of Au-Ag from two different Au concentrate (sulfuric acid washing and roasting) under various experiment conditions (thiourea concentration, pH of solvent, temperature) by thiourea solvent. The result of extraction experiment showed that the Au-Ag extraction was a fast extraction process, reaching equilibrium (maximum extraction rate) within 30 min. The Au-Ag extraction rate was higher in the roasted concentrate than in the sulfuric acid washing. The higher the Au-Ag extraction rate (Au - 70.87%, Ag - 98.12%) from roasted concentrate was found when the more concentration of thiourea increased, pH decreased and extraction temperature increased. This study informs extraction method basic knowledge when thiourea was a possibility to eco-/economic resources of Au-Ag utilization studies including the hydrometallurgy.

    Highlights: • An inversed Au/ZnO nanostructure was fabricated with ZnO loaded onto Au. • The Au/ZnO nanocomposites showed enhanced properties in visible-light photocatalysis. • The SPR effect of Au was considered important for visible-light photocatalysis. - Abstract: In this paper, we fabricate Au/ZnO nanostructure with smaller ZnO nanoparticles loaded onto bigger gold nanoparticles via combining seed-mediated method and sol-gel method. The obtained Au/ZnO nanocomposites exhibit excellent properties in photocatalysis process like methyl orange (MO) degradation and oxidative conversion of methanol into formaldehyde under visible light irradiation. The enhanced properties were ascribed to the surface plasmon resonance (SPR) effect of Au nanoparticles, which could contribute to the separation of photo-excited electrons and holes and facilitate the process of absorbing visible light. This paper contributes to the emergence of multi-functional nanocomposites with possible applications in visible-light driven photocatalysts and makes the Au/ZnO photocatalyst an exceptional choice for practical applications such as environmental purification of organic pollutants in aqueous solution and the synthesis of fine chemicals and intermediates.

  2. Using supported Au nanoparticles as starting material for preparing uniform Au/Pd bimetallic catalysts

    One of the best methods for producing bulk homogeneous (composition) supported bimetallic AuPd clusters involves the immobilization of a protected Au seed followed by the addition of Pd. This paper investigates the importance of this gold seed in controlling the resulting bimetallic AuPd clusters structures, sizes and catalytic activities by investigating three different gold seeds. Uniform Au-Pd alloy were obtained when a steric/electrostatic protecting group, poly(vinyl alcohol) (PVA), was used to form the gold clusters on activated carbon (AC). In contrast Au/AC precursors prepared using Au nanoparticles with only electrostatic stabilization (tetrakis(hydroxypropyl)phosphonium chloride (THPC)), or no stabilization (magnetron sputtering) produced inhomogeneous alloys and segregation of the gold and palladium. The uniform alloyed catalyst (Pd{at}Au{sub PVA}/AC) is the most active and selective catalyst, while the inhomogenous catalysts are less active and selective. Further study of the PVA protected Au clusters revealed that the amount of PVA used is also critical for the preparation of uniform alloyed catalyst, their stability, and their catalytic activity.

  6. Low-temperature solution synthesis of the non-equilibrium ordered intermetallic compounds Au3Fe, Au3Co, and Au3Ni as nanocrystals. (United States)

    Vasquez, Yolanda; Luo, Zhiping; Schaak, Raymond E


    Alloys and intermetallic compounds of Au with the 3d transition metals Fe, Co, and Ni are nonequilibrium phases that have many useful potential applications as catalytic, magnetic, optic, and multifunctional magneto-optic materials. However, the atomically ordered Au-M (M = Fe, Co, Ni) intermetallics are particularly elusive from a synthetic standpoint. Here we report the low-temperature solution synthesis of the L12 (Cu3Au-type) intermetallic compounds Au3Fe, Au3Co, and Au3Ni using n-butyllithium as a reducing agent. Reaction pathway studies for the Au3Co system indicate that Au nucleates first, followed by Co incorporation to form the intermetallic. The nonequilibrium intermetallic nanocrystals have been characterized by powder XRD, TEM, EDS, selected area electron diffraction, and nanobeam electron diffraction, which collectively confirm the compositions and superlattice structures.

  3. Jets and dijets in Au+Au and p+p collisions at RHIC

    Energy Technology Data Exchange (ETDEWEB)

    Hardtke, D.; STAR Collaboration


    Recent data from RHIC suggest novel nuclear effects in the production of high p{sub T} hadrons. We present results from the STAR detector on high p{sub T} angular correlations in Au+Au and p+p collisions at {radical}S = 200 GeV/c. These two-particle angular correlation measurements verify the presence of a partonic hard scattering and fragmentation component at high p{sub T} in both central and peripheral Au+Au collisions. When triggering on a leading hadron with p{sub T}>4 GeV, we observe a quantitative agreement between the jet cone properties in p+p and all centralities of Au+Au collisions. This quantitative agreement indicates that nearly all hadrons with p{sub T}>4 GeV/c come from jet fragmentation and that jet fragmentation properties are not substantially modified in Au+Au collisions. STAR has also measured the strength of back-to-back high p{sub T} charged hadron correlations, and observes a small suppression of the back-to-back correlation strength in peripheral collisions, and a nearly complete disappearance o f back-to-back correlations in central Au+Au events. These phenomena, together with the observed strong suppression of inclusive yields and large value of elliptic flow at high p{sub T}, are consistent with a model where high p{sub T} hadrons come from partons created near the surface of the collision region, and where partons that originate or propagate towards the center of the collision region are substantially slowed or completely absorbed.

    Au/Cu bilayers with different Au:Cu concentrations (25:75, 50:50 and 75:25 at.%) were deposited on Si(100) substrates by thermal evaporation. The thicknesses of all Au/Cu bilayers were 150 nm. The alloys were prepared by thermal diffusion into a vacuum oven with argon atmosphere at 690 K during 1 h. X-ray diffraction analysis revealed different phases of AuCu and CuSi alloys in the samples after annealing process. CuSi alloys were mainly obtained for 25:75 at.% samples, meanwhile the AuCuII phase dominates for samples prepared with 50:50 at.%. Additionally, the Au:Cu alloys with 75:25 at.%, produce Au{sub 2}Cu{sub 3} and Au{sub 3}Cu phases. The formed alloys were characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), transmission electron microscopy (TEM) and energy dispersive spectroscopy (EDS) to study the morphology and the elemental concentration of the formed alloys. - Highlights: • AuCu/Si alloy thin films were prepared by thermal diffusion. • Alloys prepared with 50 at.% of Au produce the AuCuII phase. • Alloys prepared with 75 at.% of Au produce Au{sub 3}Cu and Au{sub 2}Cu{sub 3} phases. • All alloys present diffusion of Si and Cu through the CuSi alloy formation.

    Questo contributo presenta, all’interno dell’obiettivo di definizione del capitale sociale della popolazione adolescenziale del saluzzese, la lettura del profilo di salute dei residenti del distretto 1 dell’ASL 17 del Piemonte, utile per la progettazione di interventi educativi di prevenzione primaria nella popolazione giovanile.

    Obiettivo: indagare i bisogni di salute e identificare le disuguaglianze sociali di salute degli adolescenti della Comunità del saluzzese.

    Metodi: sono stati estratti i dati demografici (2000, i dati di mortalità (1995-97 e i dati di morbosità (1998 relativi alla popolazione 14-19 anni in 36 Comuni e a quella regionale. Gli indicatori utilizzati nell’indagine sono stati il rapporto standardizzato di mortalità e il tasso standardizzato anni di vita persi a 75 anni, il tasso di ospedalizzazione, la percentuale di ricoveri non programmati, il tasso di primo ricovero e il rischio relativo. Risultati: la popolazione residente è di 74.526 persone (36.825 maschi, 37.701 femmine con 4.072 unità di età tra i 14 e i 19 anni. La mortalità per tutte le cause nei giovani evidenzia un eccesso significativo di due volte e mezzo rispetto ai dati regionali (RR 2,60; IC95% 145,62-416,77. Tale valore è riferibile all’incremento delle morti accidentali, da trasporto e da malattie alcool correlate. La morbosità per tutte le cause risulta essere il 6% superiore (maschi e il 2% inferiore (femmine rispetto al dato regionale; tali valori sono in linea con quelli dei distretti adiacenti. È in corso di analisi l’indagine qualitativa nella Comunità in studio. I risultati dei due rami della ricerca, quantitativo e qualitativo, verranno presentati nel corso dell’anno insieme a ipotesi di ricostruzione dei meccanismi che operano nella generazione delle disuguaglianze sociali di salute negli adolescenti sul territorio interessato.

    Lactobacillus para paracasei are used commonly as functional food and probiotic substances. In this work Au nanoparticles self-assembled films were used for Lactobacillus para paracasei determination at five different concentrations. Functionalized substrates were immersed in a colloidal solution for one and a half hour at room temperature and dried at room temperature during four hours. After that, drops of Lactobacillus para paracasei in aqueous solution were put into the Au nanoparticles film and let dry at room temperature for another two hours. Infrared spectroscopy in attenuated total reflectance sampling mode was used to observe generation peaks due to substrate silanization, enhancement of Si-O band intensity due to the Au colloids added to silanized substrate and also to observe the enhancement of Lactobacillus para paracasei infrared intensity of the characteristic frequencies at 1650, 1534 and 1450 cm{sup -1} due to surface enhancement infrared absorption.

  10. PHENIX Results in d + Au Collisions (United States)

    Chen, Chin-Hao


    The PHENIX experiment at the Relativistic Heavy Ion Collider has performed a comprehensive set of measurements in d + Au collisions. Observables in d + Au collisions were originally conceived as a control experiment where no quark-gluon plasma is formed and one could isolate so-called cold nuclear matter effects, including nuclear modified parton distributions and parton multiple scattering. However, recent data from the PHENIX experiment in d + Au, in conjunction with new p + Pb results at the Large Hadron Collider, give strong evidence for a very different picture. We present new results that hint at the formation of a small quark-gluon plasma, that though short lived, leaves a fingerprint of evidence on final state observables. These new results will be discussed in the context of competing theoretical interpretations.

  12. Au nanorice assemble electrolytically into mesostars. (United States)

    Bardhan, Rizia; Neumann, Oara; Mirin, Nikolay; Wang, Hui; Halas, Naomi J


    Star-shaped mesotructures are formed when an aqueous suspension of Au nanorice particles, which consist of prolate hematite cores and a thin Au shell, is subjected to an electric current. The nanorice particles assemble to form hyperbranched micrometer-scale mesostars. To our knowledge, this is the first reported observation of nanoparticle assembly into larger ordered structures under the influence of an electrochemical process (H(2)O electrolysis). The assembly is accompanied by significant modifications in the morphology, dimensions, chemical composition, crystallographic structure, and optical properties of the constituent nanoparticles.

  13. On the Stark broadening in the Au I and Au II spectra from a helium plasma (United States)

    Djeniže, S.


    The Stark FWHM (Full-Width at Half of the Maximal line intensity, W) of 5 neutral and 26 singly ionized gold (Au I and Au II, respectively) spectral lines have been measured in laboratory helium plasma at approximately 16,600 K electron temperature and 7.4 × 10 22 m - 3 electron density. Five Au I and ten Au II W values are reported for the first time. The Au II W values are compared with recent theoretical data, calculated based on a modified semi-empirical approach, and also with existing experimental W values. Our normalized Stark widths are six times higher than those measured in a laser-produced plasma. Possible explanation of this is recommended here. An agreement (within the accuracy of the experiment and uncertainties of the theoretical approach used) with the recently calculated W data was found in the 6p-7s Au II transition. The calculated hyperfine splitting for the five Au II lines in the 6s-6p transition is also presented. At the stated helium plasma conditions, Stark broadening has been found to be the dominant mechanism in the Au I and Au II line shape formation. A modified version of the linear low-pressure pulsed arc was used as a plasma source operated in helium, with gold atoms as impurities evaporated from the thin gold cylindrical plates located in the homogeneous part of the discharge, providing conditions free of self-absorption. This plasma source ensures good conditions for generation of excited gold ions due to Penning and charge exchange effects.

    Full Text Available "We want our young people exposed to ICT in school from the very beginning, and we want teachers who are confident to share their knowledge", mit diesen Aussagen der EU-Kommissarin for Education, Nellie Kroes (Europäische Kommision, 2013, wird deutlich, dass LehrerInnen aufgefordert sind, den ihnen anvertrauten Kindern einen sinnvollen Umgang mit Medien nahe zu bringen. Wie wichtig das Ausbilden dieser Fähigkeiten und das Erwerben der Kenntnisse in diesem Bereich ist, kann durch die Tatsache, dass die Europäische Union digitale Kompetenz zu einer der acht Schlüsselkompetenzen zählt und von der Europäischen Kommission in ihrer "Digitalen Agenda" (Europäische Kommission, 2006 nachweislich eingefordert wird, erkannt werden. Studien, wie beispielsweise die 3. Oö. Kinder-Medien-Studie (Oö. Kinder-Medien-Studie, 2012 belegen, dass Kinder bereits vor dem Schuleintritt mit neuen Technologien und dem Internet Erfahrungen sammeln. Diese Erkenntnisse führen zur Fragestellung, welche Maßnahmen im schulischen Kontext gesetzt werden müssen, um SchülerInnen im Bereich der Medienbildung zu unterstützen und auf den individuellen und kollektiven Habitus im Bereich der Medienbildung einzugehen. Eine Arbeitsgruppe mit ExpertInnen (digi.komp, 2013a erstellte im Auftrag des Bundesministeriums für Unterricht, Kunst und Kultur zu diesem Zweck einen Referenzrahmen für digitale Kompetenzen für SchülerInnen des Primarbereichs. Dieses digitale Kompetenzmodell mit zahlreichen Anwendungsbeispielen ermöglicht allen SchulpartnerInnen in Österreich eine Orientierung beim Arbeiten mit "Neuen" Medien. Es soll SchülerInnen dazu befähigen, dass sie am Ende der vierten Schulstufe Kompetenzen im Bereich der ICT aufweisen.

    Full Text Available Taking the cue from a reading of Agamben’s essay Nudity (2009, the text analyses the most famous notion of his vocabulary, «bare» or «naked life», and attempts to understand the meaning of life’s ‘nudity’ within the whole project begun with Homo Sacer. By attempting to disclose and deactivate the theological signature that determines, in our culture, the concept of ‘nudity’ in exclusively privative terms, Nudity provides both an instrument for the analysis of life’s nudity in the sovereign ban, and the model for a philosophical practice structured on a ‘denudation’ of the signatures and apparatuses which determine and imprison our life

  19. A novel Au SINE sequence found in a gymnosperm. (United States)

    Yagi, Eiki; Akita, Toru; Kawahara, Taihachi


    Although many SINE families have been identified in the animal kingdom, only a few SINE families have been identified in plants, and their distribution is somewhat limited. The Au SINE (Au) has been found discontinuously in basal angiosperms, monocots, and eudicots. In this study, we examined the presence of the Au in gymnosperms and ferns by PCR using internal primers for Au. As a result, we found Au in a gymnosperm species, Ephedra ciliata. Therefore, Au was supposed to be present in the common ancestor of angiosperms and gymnosperms. The Au in E. ciliate was 15 bp shorter than the consensus sequence, which is similar to the Au SINE found in Glycine. However, the 3'end of the Au found in E. ciliate was more similar to the 3'end of the Medicago-type Au than that of the Glycine-type Au. A phylogenetic tree indicated that the Au sequence from E. ciliate is more closely related to the sequence found in Glycine than that found in Medicago/Lotus. These results indicated that Au were present in both angiosperms and gymnosperms.

    We present transverse momentum distributions of charged hadrons produced in Au+Au collisions at {radical}S{sub NN} = 200 GeV. The evolution of the spectra for transverse momenta p{sub T} from 0.25 to 5 GeV/C is studied as a function of collision centrality. We find a significant change of the spectral shape between proton-antiproton and peripheral Au+Au collisions. When comparing peripheral to central Au+Au collisions, we find that the yields at the highest p{sub T} exhibit approximate scaling with the number of participating nucleons, rather than scaling with the number of binary collisions.

  3. Nanoporous Au: an unsupported pure gold catalyst?

    The unique properties of gold especially in low temperature CO oxidation have been ascribed to a combination of various effects. In particular, particle sizes below a few nm and specific particle-support interactions have been shown to play important roles. On the contrary, recent reports revealed that monolithic nanoporous gold (npAu) prepared by leaching a less noble metal, such as Ag, out of the corresponding alloy can also exhibit remarkably high catalytic activity for CO oxidation, even though no support is present. Therefore, it was claimed to be a pure and unsupported gold catalyst. We investigated npAu with respect to its morphology, surface composition and catalytic properties. In particular, we studied the reaction kinetics for low temperature CO oxidation in detail taking mass transport limitation due to the porous structure of the material into account. Our results reveal that Ag, even if removed almost completely from the bulk, segregates to the surface resulting in surface concentrations of up to 10 at%. Our data suggest that this Ag plays a significant role in activation of molecular oxygen. Therefore, npAu should be considered as a bimetallic catalyst rather than a pure Au catalyst.

    Kernprobleme schulischer Bildung sind die zunehmenden Verluste an Realitäts- und Praxisbezug sowie die einseitige Betonung der fachwissenschaftlichen Kenntnisse. In jüngster Zeit werden insbesondere moderne didaktisch-methodische Konzepte näher diskutiert und praktiziert. So finden sich etwa die Stichwörter Handlungsorientierter Unterricht und Offener Unterricht in der fachdidaktischen Diskussion wieder. Eine wesentlich aktuellere Form stellt das außerschulische Lernen dar. Ein modernes pädagogisches Verständnis sieht den Unterricht heute nicht mehr als ausschließliche Tätigkeit des Lehrers an, sondern als Aktivität der Lernenden. Außerschulisches Lernen beschreibt die originale Begegnung im Unterricht außerhalb des Klassenzimmers. An außerschulischen Lernorten findet eine unmittelbare AuseinanderSetzung des Lernenden mit seiner räumlichen Umgebung statt. Charakteristisch sind hierbei vor allem die aktive(Mit-)Gestaltung sowie die eigenständige Wahrnehmung mehrperspektivischer Bildungsinhalte d...

  10. Characterization of Au and Bimetallic PtAu Nanoparticles on PDDA-Graphene Sheets as Electrocatalysts for Formic Acid Oxidation (United States)

    Yung, Tung-Yuan; Liu, Ting-Yu; Huang, Li-Ying; Wang, Kuan-Syun; Tzou, Huei-Ming; Chen, Po-Tuan; Chao, Chi-Yang; Liu, Ling-Kang


    Nanocomposite materials of the Au nanoparticles (Au/PDDA-G) and the bimetallic PtAu nanoparticles on poly-(diallyldimethylammonium chloride) (PDDA)-modified graphene sheets (PtAu/PDDA-G) were prepared with hydrothermal method at 90 °C for 24 h. The composite materials Au/PDDA-G and PtAu/PDDA-G were evaluated by transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and thermogravimetric analysis (TGA) for exploring the structural characterization for the electrochemical catalysis. According to TEM results, the diameter of Au and bimetallic PtAu nanoparticles is about 20-50 and 5-10 nm, respectively. X-ray diffraction (XRD) results indicate that both of PtAu and Au nanoparticles exhibit the crystalline plane of (111), (200), (210), and (311). Furthermore, XRD data also show the 2°-3° difference between pristine graphene sheets and the PDDA-modified graphene sheets. For the catalytic activity tests of Au/PDDA-G and PtAu/PDDA-G, the mixture of 0.5 M aqueous H2SO4 and 0.5 M aqueous formic acid was used as model to evaluate the electrochemical characterizations. The catalytic activities of the novel bimetallic PtAu/graphene electrocatalyst would be anticipated to be superior to the previous electrocatalyst of the cubic Pt/graphene.

    Directed flow of deuterons, tritons, $^3$He, and $^4$He is studied in Au+Au collisions at a beam momentum of about 10.8 $A$ GeV/c. Flow of all particles is analyzed as a function of transverse momentum for different centralities of the collision. The directed flow signal, $v_1(p_t)$, is found to increase with particle mass. This mass dependence is strongest in the projectile rapidity region.

    Spach, David H; Wood, Brian R; Karpenko, Andrew; Unruh, Kenton T; Kinney, Rebecca G; Roscoe, Clay; Nelson, John


    In recent years, the HIV care provider workforce has not kept pace with an expanding HIV epidemic. To effectively address this HIV workforce shortage, a multipronged approach is needed that includes high-quality, easily accessible, up-to-date HIV education for trainees and practicing providers. Toward this objective, the University of Washington, in collaboration with the AIDS Education and Training Center National Coordinating Resource Center, is developing a modular, dynamic curriculum that addresses the entire spectrum of the HIV care continuum. Herein, we outline the general principles, content, organization, and features of this federally funded National HIV Curriculum, which allows for longitudinal, active, self-directed learning, as well as real-time evaluation, tracking, and feedback at the individual and group level. The online curriculum, which is in development, will provide a free, comprehensive, interactive HIV training and resource tool that can support national efforts to expand and strengthen the United States HIV clinical care workforce.

  5. Electronic and geometric structures of Au30 clusters: a network of 2e-superatom Au cores protected by tridentate protecting motifs with u3-S. (United States)

    Tian, Zhimei; Cheng, Longjiu


    Density functional theory calculations have been performed to study the experimentally synthesized Au30S(SR)18 and two related Au30(SR)18 and Au30S2(SR)18 clusters. The patterns of thiolate ligands on the gold cores for the three thiolate-protected Au30 nanoclusters are on the basis of the "divide and protect" concept. A novel extended protecting motif with u3-S, S(Au2(SR)2)2AuSR, is discovered, which is termed the tridentate protecting motif. The Au cores of Au30S(SR)18, Au30(SR)18 and Au30S2(SR)18 clusters are Au17, Au20 and Au14, respectively. The superatom-network (SAN) model and the superatom complex (SAC) model are used to explain the chemical bonding patterns, which are verified by chemical bonding analysis based on the adaptive natural density partitioning (AdNDP) method and aromatic analysis on the basis of the nucleus-independent chemical shift (NICS) method. The Au17 core of the Au30S(SR)18 cluster can be viewed as a SAN of one Au6 superatom and four Au4 superatoms. The shape of the Au6 core is identical to that revealed in the recently synthesized Au18(SR)14 cluster. The Au20 core of the Au30(SR)18 cluster can be viewed as a SAN of two Au6 superatoms and four Au4 superatoms. The Au14 core of Au30S2(SR)18 can be regarded as a SAN of two pairs of two vertex-sharing Au4 superatoms. Meanwhile, the Au14 core is an 8e-superatom with 1S(2)1P(6) configuration. Our work may aid understanding and give new insights into the chemical synthesis of thiolate-protected Au clusters.

    Chen, S-H; Wang, D-C; Chen, G-Y; Chen, K-Y [Graduate School of Engineering Science and Technology, National Yunlin University of Science and Technology, Taiwan (China)


    The self-assembled fabrication of nanostructure, a dreaming approach in the area of fabrication engineering, is the ultimate goal of this research. A finding was proved through previous research that the size of the self-assembled gold nanoparticles could be controlled with the mole ratio between AuCl{sub 4}{sup -} and thiol. In this study, the moles of Au were fixed, only the moles of thiol were adjusted. Five different mole ratios of Au/S with their effect on size uniformity were investigated. The mole ratios were 1:1/16, 1:1/8, 1:1, 1:8, 1:16, respectively. The size distributions of the gold nanoparticles were analyzed by Mac-View analysis software. HR-TEM was used to derive images of self-assembled gold nanoparticles. The result reached was also the higher the mole ratio between AuCl{sub 4}{sup -} and thiol the bigger the self-assembled gold nanoparticles. Under the condition of moles of Au fixed, the most homogeneous nanoparticles in size distribution derived with the mole ratio of 1:1/8 between AuCl{sub 4}{sup -} and thiol. The obtained nanoparticles could be used, for example, in uniform surface nanofabrication, leading to the fabrication of ordered array of quantum dots.

  7. Effects of Excimer Irradiation Treatment on Thermocompression Au-Au Bonding (United States)

    Naoko Unami,; Katsuyuki Sakuma,; Jun Mizuno,; Shuichi Shoji,


    We studied the feasibility of using vacuum ultraviolet (VUV) treatment as a surface improvement technique with Au-Au flip-chip bonding. For fine-pitch electrical interconnections in three-dimensional (3D) stack applications, robust and reliable bonding is desirable; in this case, surface modification treatment is needed before the bonding process. A VUV surface treatment was used to remove organic contaminants. Samples of electroplated Au pads were examined by X-ray photoelectron spectroscopy (XPS) to evaluate the chemical composition of the Au surfaces. The XPS results revealed that the carbon-based contaminants on the surface were removed by the VUV treatment. The shear strength of the bonded sample was also improved. The average shear strength of a bump with VUV treatment is 1.6 times larger than that of a bump without VUV treatment. Cross-sectional scanning electron microscopy (SEM) images of the bonded samples confirmed the absence of voids and cracks. The results show that VUV treatment has clear effects on Au-Au flip-chip bonding.

    PHOBOS is one of four experiments studying the Au-Au interactions at RHIC. The data collected during the first few weeks after the RHIC start-up, using the initial configuration of the PHOBOS detector, were sufficient to obtain the first physics results for the most central collisions of Au nuclei at the center of mass energy of 56 and 130 AGeV. The pseudorapidity density of charged particles near midrapidity is shown and compared with data at lower energies and from $pp$ and $p\\bar{p}$ collisions.

  13. From the Ternary Eu(Au/In)2 and EuAu4(Au/In)2 with Remarkable Au/In Distributions to a New Structure Type: The Gold-Rich Eu5Au16(Au/In)6 Structure. (United States)

    Steinberg, Simon; Card, Nathan; Mudring, Anja-Verena


    The ternary Eu(Au/In)2 (EuAu(0.46)In(1.54(2))) (I), EuAu4(Au/In)2 (EuAu(4+x)In(2-x) with x = 0.75(2) (II), 0.93(2), and 1.03(2)), and Eu5Au16(Au/In)6 (Eu5Au(17.29)In(4.71(3))) (III) have been synthesized, and their structures were characterized by single-crystal X-ray diffraction. I and II crystallize with the CeCu2-type (Pearson Symbol oI12; Imma; Z = 4; a = 4.9018(4) Å; b = 7.8237(5) Å; c = 8.4457(5) Å) and the YbAl4Mo2-type (tI14; I4/mmm; Z = 2; a = 7.1612(7) Å; c = 5.5268(7) Å) and exhibit significant Au/In disorder. I is composed of an Au/In-mixed diamond-related host lattice encapsulating Eu atoms, while the structure of II features ribbons of distorted, squared Au8 prisms enclosing Eu, Au, and In atoms. Combination of these structural motifs leads to a new structure type as observed for Eu5Au16(Au/In)6 (Eu5Au(17.29)In(4.71(3))) (oS108; Cmcm; Z = 4; a = 7.2283(4) Å; b = 9.0499(6) Å; c = 34.619(2) Å), which formally represents a one-dimensional intergrowth of the series EuAu2-"EuAu4In2". The site preferences of the disordered Au/In positions in II were investigated for different hypothetical "EuAu4(Au/In)2" models using the projector-augmented wave method and indicate that these structures attempt to optimize the frequencies of the heteroatomic Au-In contacts. A chemical bonding analysis on two "EuAu5In" and "EuAu4In2" models employed the TB-LMTO-ASA method and reveals that the subtle interplay between the local atomic environments and the bond energies determines the structural and site preferences for these systems.

  18. Probing the quenching of CdSe/ZnS qdots by Au, Au/Ag, and Au/Pd nanoparticles. (United States)

    Han, Hyunjoo; Valle, Valerie; Maye, Mathew M


    The resonance energy transfer between CdSe/ZnS quantum dots (qdots) and three metallic nanoparticles (NPs) with different surface plasmon resonance (SPR) characteristics were studied. Gold, gold/silver and gold/palladium NPs were used as energy acceptors for qdots with donor emission at 570 nm. Due to the different spectral overlaps between the SPR signatures and qdot emission, varied energy transfer characteristics were observed. The energy transfer was quantified via the Stern-Volmer relationship, since in this study the energy transfer was collision based. The Au/Ag and Au/Pd NPs in particular showed high K(SV) values, while the Au NPs showed much lower energy transfer efficiency. Since the NPs used in this study were relatively large (d ~ 15-20 nm), the experimental system was also influenced by the NP extinction coefficients of ≈10(8) M(-1) cm(-1). To address this potential inner filter effect, the quenching profiles were normalized by SPR transmittance. The results are important to the field, as many of these classes of nanomaterials are being employed in energy transfer based studies, as well as in colorimetric sensing.

    The STAR Collaboration presents for the first time two-dimensional di-hadron correlations with identified leading hadrons in 200 GeV central Au + Au and minimum-bias d + Au collisions to explore hadronization mechanisms in the quark gluon plasma. The enhancement of the jet-like yield for leading pions in Au + Au data with respect to the d + Au reference and the absence of such an enhancement for leading non-pions (protons and kaons) are discussed within the context of a quark recombination scenario. The correlated yield at large angles, specifically in the ridge region, is found to be significantly higher for leading non-pions than pions. The consistencies of the constituent quark scaling, azimuthal harmonic model and a mini-jet modification model description of the data are tested, providing further constraints on hadronization.

  3. Curriculum or syllabus: which are we reforming? (United States)

    Burton, Julian L.; McDonald, Seonaidh


    Although the concept of 'curriculum' is complex, a common understanding of the term by those involved in medical education is essential, given the current climate of medical curriculum development and reform. It has not previously been established that such a common frame of reference exists. We polled a sample of medical educators with a range of teaching experience and responsibility in an attempt to discover what they understood by 'curriculum' (and whether or not the concept could be articulated). A sample of medical students was similarly polled. In total, 85% of staff and 34.9% of the students responded. The responses obtained were subjected to a content analysis. The answers received were polythematic in 87.5% of cases, dominant themes including 'curriculum as a syllabus', 'curriculum as a meta-syllabus', and 'curriculum as a means to an end'. Our data show that the nature of curriculum is complex and does not lend itself to dictionary-style definitions. Moreover, the majority of those polled view 'curriculum' in two-dimensional terms, tending to equate it to 'syllabus'. This may have significant implications for curriculum reform.

  4. What school curriculum promotes an inclusive education?

    Full Text Available This article discusses the meanings of the school curriculum regarding the proposal for implementing inclusive education. Based on a review of the literature, the study analyzes different perspectives of the curriculum; while analysis of the different legal devices that support inclusion used documentary research. Based on these analyses, the results indicate the direction towards Post-Critical curriculum as that which best meets the needs of building a truly inclusive school. Conclusions lead to the understanding that the trend of post-critical curriculum breaks with the ways of being and organizing schools, as well as question the absolute truth that disabled students require either different or exclusive school.

  6. Development of Curriculum of Learning through Photograph (United States)

    Suzuki, Keiko; Aoki, Naokazu; Kobayashi, Hiroyuki

    A curriculum of an integrated learning using power of photography in the junior highschool was constructed, and was experimented in the class "Seminar for Photographic Expression" of the integrated learning at a junior high school. The center of the curriculum is viewing photographs and self-expression using photography. By comparing the results of questionnaires investigation between before and after the class it is suggested that the curriculum brings about increase in self-esteem, empathy, and motivation for learning. This educational effect is really to foster ability to live self-sufficient lives. On the basis of these results curriculums which can be conducted by anyone at every junior highschool were proposed.

    Adsorption of Au on W(001) at 450 K up to multilayer structures was investigated. Temperature programmed desorption technique was used in determination of coverage dependent desorption energy (region up to one monolayer). Results were discussed in terms of competitive interactions of Au-Au and Au-W atoms. Simple procedure for prediction of faceting behavior on the interface, basing on the desorption data, was postulated. It was deduced that the Au/W(001) interface should not show faceting tendency after thermal treatment. (author)

    Effective photoswitchable europium sulfide nanocrystals with gold nanoparticles using dithiol (DDT: 1,10-decanedithiol) joint molecules, EuS-Au nanosystems, are demonstrated. The TEM image indicates the formation of EuS-Au nanosystems composed of cube-shaped EuS nanocrystals and spherical Au nanoparticles. Under visible-light irradiation, a drastic change of absorption band of EuS-Au nanosystems at around 600 nm was observed. The Faraday effects of EuS-Au nanosystems were estimated using magnetic circular dichroism (MCD) measurements. The effective change of the MCD spectra of EuS-Au nanosystems under visible-light irradiation was successfully observed at around 670 nm for the first time. The effective reversible changes in MCD spectra with the alternative irradiation cycles of visible light (>440 nm) and dark are also presented. The decrease rate of rotation angle at 670 nm of EuS-Au nanosystems is larger than that of absorbance. These results indicate that the effective change of MCD spectra of EuS-Au nanosystems would be dominated not only by a drastic change of absorption band related to enhanced LSPR of Au nanoparticles but also by specific interaction between EuS and Au in nanosystem under irradiation.

  20. Identification of sup 186 Au. alpha. activity

(Vanderbilt University, Nashville, TN (USA))


    With the use of an on-line isotope separator, the {alpha} activity of {sup 186}Au was identified for the first time. Only one {alpha} group ({ital E}{sub {alpha}}=4653{plus minus}15 keV) was observed. This transition was found not to be in coincidence with {gamma} rays so that it probably proceeds either to the {sup 182}Ir ground state or to a low-lying level whose deexciting {gamma} rays could not be detected. The {alpha}-decay branching was determined to be (8{plus minus}2){times}10{sup {minus}4}% from which a hindrance factor of 1.9{plus minus}0.9 was deduced. The 4653-keV {alpha} transition must therefore connect the 3{sup {minus}} {sup 186}Au ground state with a {sup 182}Ir level with the same spin and configuration.

  1. Au Based Nanocomposites Towards Plasmonic Applications (United States)

    Panniello, A.; Curri, M. L.; Placido, T.; Reboud, V.; Kehagias, N.; Sotomayor Torres, C. M.; Mecerreyes, D.; Agostiano, A.; Striccoli, M.


    Incorporation of nano-sized metals in polymers can transfer their unique features to the host matrix, providing nanocomposite materials with improved optical, electric, magnetic and mechanical properties. In this work, colloidal Au nanorods have been incorporated into PMMA based random co-polymer, properly functionalized with amino groups and the optical and morphological properties of the resulting nanocomposite have been investigated by spectroscopic and AFM measurements. Au nanorods have demonstrated to preserve the plasmon absorption and to retain morphological features upon the incorporation, thus making the final metal modified polymer composite exploitable for the fabrication of plasmonic devices. The prepared nanocomposites have been then patterned by Nano Imprint Lithography technique in order to demonstrate the viability of the materials towards optical applications.

  2. Near-infrared-responsive, superparamagnetic Au@Co nanochains

    Directory of Open Access Journals (Sweden)

    Varadee Vittur


    Full Text Available This manuscript describes a new type of nanomaterial, namely superparamagnetic Au@Co nanochains with optical extinctions in the near infrared (NIR. The Au@Co nanochains were synthesized via a one-pot galvanic replacement route involving a redox-transmetalation process in aqueous medium, where Au salt was reduced to form Au shells on Co seed templates, affording hollow Au@Co nanochains. The Au shells serve not only as a protective coating for the Co nanochain cores, but also to give rise to the optical properties of these unique nanostructures. Importantly, these bifunctional, magneto-optical Au@Co nanochains combine the advantages of nanophotonics (extinction at ca. 900 nm and nanomagnetism (superparamagnetism and provide a potentially useful new nanoarchitecture for biomedical or catalytic applications that can benefit from both activation by light and manipulation using an external magnetic field.

  3. Tuning the collective switching behavior of azobenzene/Au hybrid materials: flexible versus rigid azobenzene backbones and Au(111) surfaces versus curved Au nanoparticles. (United States)

    Liu, Chunyan; Zheng, Dong; Hu, Weigang; Zhu, Qiang; Tian, Ziqi; Zhao, Jun; Zhu, Yan; Ma, Jing


    The combination of photo-responsive azobenzene (AB) and biocompatible Au nanomaterials possesses potential applications in diverse fields such as biosensing and thermotherapy. To explore the influence of azobenzene moieties and Au substrates on the collective switching behavior, two different azobenzene derivatives (rigid biphenyl-controlled versus flexible alkoxyl chain-linked) and three different Au substrates (a planar Au(111) surface, curved Au 102 (SR) 44 and Au 25 (SR) 18 clusters) were chosen to form six Au@AB combinations. A reactive molecular dynamics (RMD) model considering both the torsion and inversion path was implemented to simulate the collective photo-induced cis-to-trans switching process of AB monolayers on Au substrates. The major driving force for isomerization is demonstrated to be the torsion of the C-N[double bond, length as m-dash]N-C dihedral angle, in addition to the minor contribution from an inversion pathway. The isomerization process can be divided into the preliminary conformation switching stage and the later relaxation stage, in which a gradual self-organization is observed for 40 ps. The Au substrate affects the packing structure of the AB monolayer, while the choice of different kinds of ABs tunes the intermolecular interaction in the monolayer. Flexible alkoxyl-linked F-AB may achieve much faster conversion on Au clusters than on the surface. For rigid biphenyl-based R-AB anchored on Au nanoparticles (AuNPs), a competitive torsion between the biphenyl and C-N[double bond, length as m-dash]N-C dihedral may delay the C-N[double bond, length as m-dash]N-C dihedral torsion and the following isomerization process. After the R-AB molecules were anchored on the Au(111) surface, the strong π-π stacking between biphenyl units accelerates the collective isomerization process. A curvature-dependent effect is observed for R-AB SAMs on different-sized substrates. The cooperation between functional AB monolayers and the Au substrate

  7. Interstellar Pickup Ion Observations to 38 au (United States)

    McComas, D. J.; Zirnstein, E. J.; Bzowski, M.; Elliott, H. A.; Randol, B.; Schwadron, N. A.; Sokół, J. M.; Szalay, J. R.; Olkin, C.; Spencer, J.; Stern, A.; Weaver, H.


    We provide the first direct observations of interstellar H+ and He+ pickup ions in the solar wind from 22 to 38 au. We use the Vasyliunas and Siscoe model functional form to quantify the pickup ion distributions, and while the fit parameters generally lie outside their physically expected ranges, this form allows fits that quantify variations in the pickup H+ properties with distance. By ∼20 au, the pickup ions already provide the dominant internal pressure in the solar wind. We determine the radial trends and extrapolate them to the termination shock at ∼90 au, where the pickup H+ to core solar wind density reaches ∼0.14. The pickup H+ temperature and thermal pressure increase from 22 to 38 au, indicating additional heating of the pickup ions. This produces very large extrapolated ratios of pickup H+ to solar wind temperature and pressure, and an extrapolated ratio of the pickup ion pressure to the solar wind dynamic pressure at the termination shock of ∼0.16. Such a large ratio has profound implications for moderating the termination shock and the overall outer heliospheric interaction. We also identify suprathermal tails in the H+ spectra and complex features in the He+ spectra, likely indicating variations in the pickup ion history and processing. Finally, we discover enhancements in both H+ and He+ populations just below their cutoff energies, which may be associated with enhanced local pickup. This study serves to document the release and serves as a citable reference of these pickup ion data for broad community use and analysis.

  8. Functionalized Au@Ag-Au nanoparticles as an optical and SERS dual probe for lateral flow sensing. (United States)

    Bai, Tingting; Wang, Meng; Cao, Min; Zhang, Juan; Zhang, Kangzhen; Zhou, Ping; Liu, Zhengxia; Liu, Ying; Guo, Zhirui; Lu, Xiang


    Lateral flow assay strips (LFASs) with Au nanoparticles (NPs) have been widely used as a probe for biomarkers in point-of-care testing; however, there still remain challenges in detection sensitivity and quantitative analysis. In this study, we developed a surface-enhanced Raman scattering (SERS)-based LFAS for quantitative analysis of a biomarker in the low concentration range. Moreover, apart from conventional Au NPs, three other types of citrate-capped Au-Ag bimetallic NPs: Au core with Ag shell NPs (Au@Ag NPs), rattle-like Au core in Ag-Au shell NPs (Au@Ag-Au NPs) and Ag-Au NPs were prepared and functionalized, and their solution-based SERS activities were comprehensively studied by experimental measurement and theoretical analysis. The results clearly indicated that the citrate-capped Au@Ag-Au NPs exhibited the highest SERS activity among the probes tested. Au@Ag-Au NPs were used as both optical and SERS probes in a SERS-based LFAS. In the presence of the analyte at high concentrations, a purple color appeared in the test zone. Highly sensitive and quantitative analysis was realized by measurement of SERS signals from the test lines. One of the most specific markers for cardiac injury, cardiac troponin I (cTnI), was chosen as the detection model. The detection limit of the SERS-based LFAS for cardiac troponin I was 0.09 ng/mL, lowered by nearly 50 times compared with visual results, and could be further lowered by optimization. These results demonstrated that the SERS-based LFAS using citrate-capped Au@Ag-Au NPs as probes can be a powerful tool for highly sensitive and quantitative detection of biomarkers. Graphical abstract A surface-enhanced Raman scattering (SERS)-based lateral flow assay strip using rattle-like Au core in Ag-Au shell (Au@Ag-Au) nanoparticles as probes was developed for quantitative analysis of a biomarker, with a detection limit nearly 50 times lower than that of visual assessment.

    An Au25 cluster protected by azobenzene derivative thiolates (S-Az) ([Au25(S-Az)18]-) was synthesized with the aim of producing a photoresponsive Au25 cluster. The matrix-assisted laser desorption/ionization mass spectrum of the product revealed that [Au25(S-Az)18]- was synthesized in high purity. Optical absorption spectra of [Au25(S-Az)18]- obtained before and after photoirradiation suggest that the azobenzenes in the ligands of Au25(S-Az)18 isomerize with an efficiency of nearly 100%, both from the trans to cis conformation and from the cis to trans conformation. Furthermore, the redox potential and optical absorption of Au25(S-Az)18 were found to change reversibly due to photoisomerization of azobenzenes.An Au25 cluster protected by azobenzene derivative thiolates (S-Az) ([Au25(S-Az)18]-) was synthesized with the aim of producing a photoresponsive Au25 cluster.

  10. EST Reading Curriculum & Instruction: An Alignment Analysis

    Directory of Open Access Journals (Sweden)

    Lubna Ali Mohammed


    Full Text Available In order for a curriculum to achieve its goals, it is imperative that the curriculum is coherent at all levels. In order to determine the coherency of a curriculum, the alignment of its theoretical underpinning and the label of a curriculum is one of the aspects that can be examined. The purpose of the current study was to examine if the theoretical grounding of the Yemeni EST senior secondary curriculum is in alignment with its communicative-based curriculum label. In line with its label, the reading curriculum embedded in the EST curriculum should be developed and designed based on the Communicative Language Teaching (CLT, which should be reflected in the EST reading instructional practice. In analysing the alignment of the communicative language teaching approach in the EST senior secondary school reading curriculum, the primary focus of the analysis was on the major SLA theories and L2 reading theories and the related instructional approaches. The data for this study were collected via an ESP textbook review as well as from the observation of the EST reading classroom instruction. The findings show that the EST senior secondary reading curriculum was not developed based on the socio-cognitive and socio-cultural theories which are the grounding principles of the communicative approach. Instead, the findings show that the EST senior secondary reading curriculum was primarily developed based on the cognitive information processing theory, in which teaching instruction reflects the student as an individual information processor and the focus on teaching vocabulary and grammatical rules using reading texts in non-communicative manner.

  12. Photocatalysis enhancement of Au/BFO nanoparticles using plasmon resonance of Au NPs

    Energy Technology Data Exchange (ETDEWEB)

    Zhang, Yan; Cai, Zhongyang; Ma, Xueming, E-mail:


    BiFeO{sub 3} (BFO) nanoparticles was synthesized via sol–gel technique, and successfully loaded with small sizes of gold nanoparticles (Au NPs) by impregnation-reduction method to extremely enhance the BFO photocatalytic activity. The obviously stronger optical absorption of Au/BFO observed from the UV–vis diffuse reflectance spectrum confirmed that the surface plasmon resonance (SPR) effect occured on the surface of Au NPs. And the surface plasmon-induced localized electric field could allow the formation of electron/hole pairs in the near surface region of BFO which can migrate to the surface without undergoing electron/hole (e{sup −}/h{sup +}) pair recombination. The more electrons and holes formed, the more ·OH will be generated to decompose the CR solution. When the gold loading in Au/BFO nanoparticles is 3.36 wt%, the obtained Au/BFO catalyst exhibits best photocatalytic activity evaluated by photocatalysis degradation of Congo red (CR) solution under the visible light irradiation.

  19. Virus-templated Au and Au/Pt Core/shell Nanowires and Their Electrocatalytic Activitives for Fuel Cell Applications (United States)



    A facile synthetic route was developed to make Au nanowires (NWs) from surfactant-mediated bio-mineralization of a genetically engineered M13 phage with specific Au binding peptides. From the selective interaction between Au binding M13 phage and Au ions in aqueous solution, Au NWs with uniform diameter were synthesized at room temperature with yields greater than 98 % without the need for size selection. The diameters of Au NWs were controlled from 10 nm to 50 nm. The Au NWs were found to be active for electrocatalytic oxidation of CO molecules for all sizes, where the activity was highly dependent on the surface facets of Au NWs. This low-temperature high yield method of preparing Au NWs was further extended to the synthesis of Au/Pt core/shell NWs with controlled coverage of Pt shell layers. Electro-catalytic studies of ethanol oxidation with different Pt loading showed enhanced activity relative to a commercial supported Pt catalyst, indicative of the dual functionality of Pt for the ethanol oxidation and Au for the anti-poisoning component of Pt. These new one-dimensional noble metal NWs with controlled compositions could facilitate the design of new alloy materials with tunable properties. PMID:24910712

  20. Au 38 (SPh) 24 : Au 38 Protected with Aromatic Thiolate Ligands

    Energy Technology Data Exchange (ETDEWEB)

    Rambukwella, Milan; Burrage, Shayna; Neubrander, Marie; Baseggio, Oscar; Aprà, Edoardo; Stener, Mauro; Fortunelli, Alessandro; Dass, Amala


    Au38(SR)24 is one of the most extensively investigated gold nanomolecules along with Au25(SR)18 and Au144(SR)60. However, so far it has only been prepared using aliphatic-like ligands, where R = –SC6H13, -SC12H25 and –SCH2CH2Ph. Au38(SCH2CH2Ph)24 when reacted with HSPh undergoes core-size conversion to Au36(SPh)24, and existing literature suggest that Au38(SPh)24 cannot be synthesized. Here, contrary to prevailing knowledge, we demonstrate that Au38(SPh)24 can be prepared if the ligand exchanged conditions are optimized, without any formation of Au36(SPh)24. Conclusive evidence is presented in the form of MALDI-MS, ESI-MS characterization, and optical spectra of Au38(SPh)24 in a solid glass form showing distinct differences from that of Au38(S-aliphatic)24. Theoretical analysis confirms experimental assignment of the optical spectrum and shows that the stability of Au38(SPh)24 is comparable to that of its aliphatic analogues, but results from different physical origins, with a significant component of ligand-ligand attractive interactions.

  2. Au99(SPh)42 nanomolecules: aromatic thiolate ligand induced conversion of Au144(SCH2CH2Ph)60. (United States)

    Nimmala, Praneeth Reddy; Dass, Amala


    A new aromatic thiolate protected gold nanomolecule Au99(SPh)42 has been synthesized by reacting the highly stable Au144(SCH2CH2Ph)60 with thiophenol, HSPh. The ubiquitous Au144(SR)60 is known for its high stability even at elevated temperature and in the presence of excess thiol. This report demonstrates for the first time the reactivity of the Au144(SCH2CH2Ph)60 with thiophenol to form a different 99-Au atom species. The resulting Au99(SPh)42 compound, however, is unreactive and highly stable in the presence of excess aromatic thiol. The molecular formula of the title compound is determined by high resolution electrospray mass spectrometry (ESI-MS) and confirmed by the preparation of the 99-atom nanomolecule using two ligands, namely, Au99(SPh)42 and Au99(SPh-OMe)42. This mass spectrometry study is an unprecedented advance in nanoparticle reaction monitoring, in studying the 144-atom to 99-atom size evolution at such high m/z (∼12k) and resolution. The optical and electrochemical properties of Au99(SPh)42 are reported. Other substituents on the phenyl group, HS-Ph-X, where X = -F, -CH3, -OCH3, also show the Au144 to Au99 core size conversion, suggesting minimal electronic effects for these substituents. Control experiments were conducted by reacting Au144(SCH2CH2Ph)60 with HS-(CH2)n-Ph (where n = 1 and 2), bulky ligands like adamantanethiol and cyclohexanethiol. It was observed that conversion of Au144 to Au99 occurs only when the phenyl group is directly attached to the thiol, suggesting that the formation of a 99-atom species is largely influenced by aromaticity of the ligand and less so on the bulkiness of the ligand.

  3. A Glance at International Curriculum Perspectives. Towards a Democratic, Deliberative and Living Curriculum

    Directory of Open Access Journals (Sweden)

    Hugo Rangel Torrijo


    Full Text Available This paper presents a reflection on the main principles (theoretical and socio-political involved in the formulation of a curriculum proposal. We note the tension between the respective positions of a formal or set curriculum versus a hidden or lived curriculum. We argue that it is imperative that this unnecessary polarization be left behind by means of a democratic proposal of curricular policy. We posit an approach that we call living curriculum, a proposal that is, on the one hand, anchored in social practices and, on the other, entails the amalgamation of the component stages of the curriculum. It involves a democratic process of curriculum renewal, since its implementation must be participatory in order for it to be anchored in social practices. Likewise, it must involve an evaluation that mobilizes stakeholders and generates knowledge for the renewal of both the curriculum as well as the educational institutions.

    Chaney, Kristin P; Macik, Maria L; Turner, Jacqueline S; Korich, Jodi A; Rogers, Kenita S; Fowler, Debra; Scallan, Elizabeth M; Keefe, Lisa M

    Curricular review is considered a necessary component for growth and enhancement of academic programs and requires time, energy, creativity, and persistence from both faculty and administration. At Texas A&M College of Veterinary Medicine & Biomedical Sciences (TAMU), the faculty and administration partnered with the university's Center for Teaching Excellence to create a faculty-driven, data-enhanced curricular redesign process. The 8-step process begins with the formation of a dedicated faculty curriculum design team to drive the redesign process and to support the college curriculum committee. The next steps include defining graduate outcomes and mapping the current curriculum to identify gaps and redundancies across the curriculum. Data are collected from internal and external stakeholders including veterinary students, faculty, alumni, and employers of graduates. Data collected through curriculum mapping and stakeholder engagement substantiate the curriculum redesign. The guidelines, supporting documents, and 8-step process developed at TAMU are provided to assist other veterinary schools in successful curricular redesign. This is the first of a two-part report that provides the background, context, and description of the process for charting the course for curricular change. The process involves defining expected learning outcomes for new graduates, conducting a curriculum mapping exercise, and collecting stakeholder data for curricular evaluation (steps 1-4). The second part of the report describes the development of rubrics that were applied to the graduate learning outcomes (steps 5-8) and engagement of faculty during the implementation phases of data-driven curriculum change.

  14. Charge transport through O-deficient Au-MgO-Au junctions

    KAUST Repository

    Fadlallah, M. M.


    Metal-oxide heterostructures have been attracting considerable attention in recent years due to various technological applications. We present results of electronic structure and transport calculations for the Au-MgO-Au (metal-insulator-metal) heterostructure based on density-functional theory and the nonequilibrium Green’s functions method. The dependence of the conductance of the heterostructure on the thickness of the MgO interlayer and the interface spacing is studied. In addition, we address the effects of O vacancies. We observe deviations from an exponentially suppressed conductance with growing interlayer thickness caused by Au-O chemical bonds. Electronic states tracing back to O vacancies can increase the conductance. Furthermore, this effect can be enhanced by enlarging the interface spacing as the vacancy induced Mg states are shifted toward the Fermi energy.

  15. [European curriculum for further education in radiology]. (United States)

    Ertl-Wagner, B


    The European training curriculum for radiology of the European Society of Radiology (ESR) aims to harmonize training in radiology in Europe. Levels I and II constitute the centerpiece of the curriculum. The ESR recommends a 5-year training period in radiology with 3 years of level I and 2 years of level II training. The undergraduate (U) level curriculum is conceived as a basis for teaching radiology in medical schools and consists of a modality-oriented U1 level and an organ-based U2 level. Level III curricula provide contents for subspecialty and fellowship training after board certification in radiology. The curricular contents of all parts of the European Training Curriculum are divided into the sections knowledge, skills as well as competences and attitudes. The European training curriculum is meant to be a recommendation and a basis for the development of national curricula, but is not meant to replace existing national regulations.

    Elliptic flow from nuclear collisions is a hadronic observable sensitive to the early stages of system evolution. We report first results on elliptic flow of charged particles at midrapidity in Au+Au collisions at sqrt(s_NN)=130 GeV using the STAR TPC at RHIC. The elliptic flow signal, v_2, averaged over transverse momentum, reaches values of about 6% for relatively peripheral collisions and decreases for the more central collisions. This can be interpreted as the observation of a higher degree of thermalization than at lower collision energies. Pseudorapidity and transverse momentum dependence of elliptic flow are also presented.

    The first measurements of light antinucleus production in Au + Au collisions at the Relativistic Heavy-Ion Collider are reported. The observed production rates for d and /sup 3/He are much larger than in lower energy nucleus-nucleus collisions. A coalescence model analysis of the yields indicates that there is little or no increase in the antinucleon freeze-out volume compared to collisions at CERN SPS energy. These analyses also indicate that the 3He freeze-out volume is smaller than the d freeze-out volume. (22 refs).

    Ying Yuan


    Full Text Available Nuclear stopping in central Au+Au collisions at relativistic heavy-ion collider (RHIC energies is studied in the framework of a cascade mode and the modified ultrarelativistic quantum molecular dynamics (UrQMD transport model. In the modified mode, the mean field potentials of both formed and “preformed” hadrons (from string fragmentation are considered. It is found that the nuclear stopping is increasingly influenced by the mean-field potentials in the projectile and target regions with the increase of the reaction energy. In the central region, the calculations of the cascade model considering the modifying factor can describe the experimental data of the PHOBOS collaboration.

  20. Relativistic multireference many-body perturbation theory calculations on Au64+ - Au69+ ions

    Energy Technology Data Exchange (ETDEWEB)

    Vilkas, M J; Ishikawa, Y; Trabert, E


    Many-body perturbation theory (MBPT) calculations are an adequate tool for the description of the structure of highly charged multi-electron ions and for the analysis of their spectra. They demonstrate this by way of a re-investigation of n=3, {Delta}n=0 transitions in the EUV spectra of Na-, Mg-, Al-like, and Si-like ions of Au that have been obtained previously by heavy-ion accelerator based beam-foil spectroscopy. They discuss the evidence and propose several revisions on the basis of the multi-reference many-body perturbation theory calculations of Ne- through P-like ions of Au.

  1. Measurements of direct photons in Au+Au collisions with PHENIX

    CERN Document Server

    Bannier, Benjamin


    The PHENIX experiment has published direct photon yields and elliptic flow coefficients $v_2$ from Au+Au collisions at RHIC energies. These results have sparked much theoretical discussion. The measured yields and flow parameters are difficult to reconcile in current model calculations of thermal radiation based on hydrodynamic time evolution of the collision volume. Our latest analyses which use high statistics data from the 2007 and 2010 runs allow the determination of direct photon yields with finer granularity in centrality and photon momentum and down to $p_T$ as low as 0.4 GeV/$c$. We will summarize the current status and present new results from PHENIX.

  2. Au/Pd core-shell nanoparticles with varied hollow Au cores for enhanced formic acid oxidation (United States)

    Hsu, Chiajen; Huang, Chienwen; Hao, Yaowu; Liu, Fuqiang


    A facile method has been developed to synthesize Au/Pd core-shell nanoparticles via galvanic replacement of Cu by Pd on hollow Au nanospheres. The unique nanoparticles were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, transmission electron microscopy, ultraviolet-visible spectroscopy, and electrochemical measurements. When the concentration of the Au solution was decreased, grain size of the polycrystalline hollow Au nanospheres was reduced, and the structures became highly porous. After the Pd shell formed on these Au nanospheres, the morphology and structure of the Au/Pd nanoparticles varied and hence significantly affected the catalytic properties. The Au/Pd nanoparticles synthesized with reduced Au concentrations showed higher formic acid oxidation activity (0.93 mA cm-2 at 0.3 V) than the commercial Pd black (0.85 mA cm-2 at 0.3 V), suggesting a promising candidate as fuel cell catalysts. In addition, the Au/Pd nanoparticles displayed lower CO-stripping potential, improved stability, and higher durability compared to the Pd black due to their unique core-shell structures tuned by Au core morphologies.

  3. Conductive Au nanowires regulated by silk fibroin nanofibers (United States)

    Dong, Bo-Ju; Lu, Qiang


    Conductive Au-biopolymer composites have promising applications in tissue engineering such as nerve tissue regeneration. In this study, silk fibroin nanofibers were formed in aqueous solution by regulating silk self-assembly process and then used as template for Au nanowire fabrication. We performed the synthesis of Au seeds by repeating the seeding cycles for several times in order to increase the density of Au seeds on the nanofibers. After electroless plating, densely decorated Au seeds grew into irregularly shaped particles following silk nanofiber to fill the gaps between particles and finally form uniform continuous nanowires. The conductive property of the Au-silk fibroin nanowires was studied with current-voltage ( I-V) measurement. A typical ohmic behavior was observed, which highlighted their potential applications in nerve tissue regeneration.

  4. Lateral spreading of Au contacts on InP (United States)

    Fatemi, Navid S.; Weizer, Victor G.


    The contact spreading phenomenon observed when small area Au contacts on InP are annealed at temperatures above about 400 C was investigated. It was found that the rapid lateral expansion of the contact metallization which consumes large quantities of InP during growth is closely related to the third stage in the series of solid state reactions that occur between InP and Au, i.e., to the Au3In-to-Au9In4 transition. Detailed descriptions are presented of both the spreading process and the Au3In-to-Au9In4 transition along with arguments that the two processes are manifestations of the same basic phenomenon.

    We present results on the magnetoresistance and temperature dependence of the resistivity for nanostructured Au produced by chemical means. The magnetoresistance was typical of highly disordered metals exhibiting quantum interference effects. We fitted the data and were able to determine the spin-orbit scattering relaxation time to be 10-12 s and we found the inelastic scattering time at 10 K to be 10-11 s. The inelastic scattering rate varied as T3 between 4 and 20 K, which is typical for electron-phonon scattering in disordered metals.

  12. Photosynthetic electron transport system promotes synthesis of Au-nanoparticles.

    Directory of Open Access Journals (Sweden)

    Nisha Shabnam

    Full Text Available In this communication, a novel, green, efficient and economically viable light mediated protocol for generation of Au-nanoparticles using most vital organelle, chloroplasts, of the plant system is portrayed. Thylakoids/chloroplasts isolated from Potamogeton nodosus (an aquatic plant and Spinacia oleracea (a terrestrial plant turned Au³⁺ solutions purple in presence of light of 600 µmol m⁻² s⁻¹ photon flux density (PFD and the purple coloration intensified with time. UV-Vis spectra of these purple colored solutions showed absorption peak at ∼545 nm which is known to arise due to surface plasmon oscillations specific to Au-nanoparticles. However, thylakoids/chloroplasts did not alter color of Au³⁺ solutions in dark. These results clearly demonstrated that photosynthetic electron transport can reduce Au³⁺ to Au⁰ which nucleate to form Au-nanoparticles in presence of light. Transmission electron microscopic studies revealed that Au-nanoparticles generated by light driven photosynthetic electron transport system of thylakoids/chloroplasts were in range of 5-20 nm. Selected area electron diffraction and powder X-ray diffraction indicated crystalline nature of these nanoparticles. Energy dispersive X-ray confirmed that these nanoparticles were composed of Au. To confirm the potential of light driven photosynthetic electron transport in generation of Au-nanoparticles, thylakoids/chloroplasts were tested for their efficacy to generate Au-nanoparticles in presence of light of PFD ranging from 60 to 600 µmol m⁻² s⁻¹. The capacity of thylakoids/chloroplasts to generate Au-nanoparticles increased remarkably with increase in PFD, which further clearly demonstrated potential of light driven photosynthetic electron transport in reduction of Au³⁺ to Au⁰ to form nanoparticles. The light driven donation of electrons to metal ions by thylakoids/chloroplasts can be exploited for large scale production of nanoparticles.

  16. Plasmonic welding of hybrid Au-ZnO nanostructure (United States)

    Chen, Z. Y.; Yang, H. B.; Ghosh, P.; Li, Q.; Qiu, M.


    We report that 532 nm CW laser can be used to obtain non-wetting metal-semiconductor (Au-ZnO) Schottky heterojunctions by plasmonic welding. Single crystal Au and n-type ZnO nanowires are placed on gold (Au) and titanium (Ti) electrodes, respectively, and the junction welding is realized. The current-voltage (I-V) characteristic curve of the single Schottky rectifier is also measured.

  18. Conjugated electrical properties of Au nanoparticle–polyaniline network (United States)

    Usami, Yuki; Otsuka, Yoichi; Naitoh, Yasuhisa; Matsumoto, Takuya


    We investigated the electrical properties of a two-dimensional (2D) network consisting of multiple Au nanoparticles (AuNPs) and self-doped polyaniline sulfonate (SPAN). Nonlinear current–voltage (I–V) characteristics with wide variations were observed in the networks. The temperature dependence of the I–V characteristics exhibited a short localization length, suggesting conjugated electronic properties of the AuNP–SPAN network. This result provides a new direction for network-based molecular electronic devices.

  19. Measurement of the dielectron continuum in p+p and Au+Au collisions at RHIC

    CERN Document Server

    Dahms, Torsten


    PHENIX has measured the e^+e^- pair continuum in sqrt(s_NN) = 200 GeV Au+Au and p+p collisions over a wide range of mass and transverse momenta. While the p+p data in the mass range below the phi meson are well described by known contributions from light meson decays, the Au+Au minimum bias inclusive mass spectrum shows an enhancement by a factor of 4.7 +/- 0.4(stat)} +/- 1.5(syst) +/- 0.9(model) in the mass range 0.15

  20. Experimental evidence for electron localization on Au upon photo-activation of Au/anatase catalysts

    NARCIS (Netherlands)

    Carneiro, J.T.; Carneiro, Joana T.; Savenije, Tom J.; Mul, Guido


    Time resolved microwave conductivity (TRMC) measurements show that the presence of Au on anatase Hombikat UV100 significantly reduces the lifetime of mobile electrons formed by photo-excitation of this photocatalyst at 300 nm, providing evidence for the widely acclaimed electron localization effect
