    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. The digital curriculum vitae.

    2005-02-01

    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availability of electronic articles, presentations, and information via the Internet, traditional paper CVs may soon be superseded by their electronic successors.

    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.

    1985-10-01

    At times, as for example when candlelight flickers on bottle and glasses, it is not unpleasant to look into a pair of warm and friendly eyes and respond to the words "Tell me about yourself." Completing a curriculum vitae (CV), however, is a less attractive proposition, especially when applying for an appointment. Even those who are fond of talking about themselves can find it difficult. Some find it embarrassing. Some, judging from the poorly presented data which frequently accompany applications even for senior posts, are unaware of the important part the CV plays in the selection process.

    In today's challenging healthcare environment, it is essential for nurse practitioners to be able to describe themselves professionally on paper to compete for practice and academic opportunities. Nurse practitioners are competing with physician assistants as well as physicians for primary and acute care positions. A carefully compiled curriculum vitae will present the individual in the best light possible to help open career doors and enhance chances of success. Preparing a curriculum vitae will serve to highlight relevant professional accomplishments, whatever the setting, toward the fulfillment of professional goals. This article reviews the current professional print and electronic literature on preparing a curriculum vitae to assist the nurse practitioner in developing this vital document.

  11. Rutherford's curriculum vitae, 1894-1907.

    Cohen, M

    1995-06-01

    A single page, handwritten document was discovered when the Macdonald Physics building of McGill University in Montreal was gutted in 1978. This proved to be the draft of Ernest Rutherford's curriculum vitae (C.V.) covering the years 1894-1907, probably written in the autumn of 1906 when Rutherford was preparing to leave McGill. The C.V. contains 21 headings in chronological order, referring to research and other activities of Rutherford and his coauthors (especially Soddy and Barnes), plus a further set of headings relating to the associated investigations of Rutherford's team, including Eve and Hahn. A transcript of the document is provided, although in several places, Rutherford's handwriting is difficult to interpret, and the significance of his abbreviations is not always clear. Each of the items in the C.V. is discussed briefly in this review, in the light both of Rutherford's personal career and of the contribution of his team to the development and understanding of radioactivity. This contribution included the cause and nature of radioactivity (with Soddy), energy aspects of radioactive decay (with Barnes), elucidation of the uranium-radium, thorium and actinium series (Godlewski and Hahn), the radioactivity of the earth and atmosphere (Eve), the nature of the gamma rays (Eve) and, perhaps most important of all, the nature and properties of the alpha particle (Rutherford himself). The latter investigations led directly to Rutherford's later work in Manchester, including the nuclear model of the atom and artificial disintegration of the nucleus.

  18. Creating Curriculum Vitae for Understanding People on the Web

    Science.gov (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.

    The health curriculum vitae consists mainly of a chronological sequence of diagnoses, which are the mainstays of the medical record. Each diagnosis is connected vertically in the health curriculum vitae with its aetiological factors and its medical or surgical treatments in a casual concatenation; and horizontally throughout the other three parts of the record with its relevant functional, morphological (descriptive) and numerical laboratory data in a diagnostic association. The health curriculum vitae uses the Systematized Nomenclature of Medicine (SNOMED), the International Nomenclature of the Diseases of the Gastrointestinal Tract (CIOMS) and the International Standard Classification of Occupations of the Internationl Labour Office.

    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.

  3. Preparing a successful, role-specific curriculum vitae.

    2014-10-01

    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.

    Full Text Available One of the main concerns about students, students of the last year of their careers is to find the first job. The task is not so easy, since they don't have certain skills needed to deal with the labour market, including the first synthesis of curriculum design. Curriculum vitae, has been the fundamental tool for a job search; this is the document through which collects basic information about the education, training and experience of the applicant to a job. For this reason, the intention of this research is to identify the skills that have a group of University students in the design for their first resume. For this purpose, it has been developed a documentary research with a designed descriptive method, using deliberate non-probability sampling, establishing criteria for analysis in a sample of 13 curricular synthesis of the 5th quarter of organizational business enterprise from the Universidad Simon Bolivar Camuri Grande branch. Between the most relevant results that a dominant model of curriculum vitae were unable to identify, the sections are presented and perfunctorily without complying with the suggested order in the layout and printing of the document, display the use of various types of letters, designs and colors not appropriate. Finally, demonstrate that college students do not have sufficient skills required to design an instrument so important as it is the first curriculum vitae design.

    Conn, D A; Asbury, A J

    1994-07-01

    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.

    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.

  8. [Curriculum vitae aortae].

    Science.gov (United States)

    Solberg, S

    1998-12-10

    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.

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.

And the results show:(1)on demographic,the age of the senior leaders in the universities is about 55 years old,and most of them are male and Han nationality. It seems that the higher of the university level,the older of its leader. And there is still the“glass ceiling”phenomenon-the female leaders are difficult promoted in the universities,but no ethnic discrimination. (2)On academic,compared with the administrative leaders and the vice leaders,the party leaders and the principal leaders should have higher edu-cational background,professional qualifications and international level. And compared with the person who comes from other academic backgrounds,it seems that those who from science background have more opportunities to be a senior leader.(3)On working position,the higher of the university level,the richer working experiences that the senior leaders have. And the party leaders have more abundant working experience respect to the executive leaders. By the way,most of the principal leaders have the outside-system working experience and are from the external se-lection. But on the whole,internal promotion is still the main way for a leader.%以我国112所“211工程”大学的567名高层领导的履历资料为基础,对大学高层领导的群体特征进行实证分析,结果显示:(1)在人口统计学特征上,我国大学高层领导以55岁左右的汉族男性为主,越是高水平的大学,其高层领导越可能是年长者,女性难以晋升的“玻璃天花板”现象依然存在,但不存在民族歧视;(2)在学术特征上,行政领导相对于党委领导、正职领导相对于副职领导,无论是学历、职称还是国际化水平上都有着更高的要求,且理工科背景出身相比其他背景来说,担任高层领导的机会更大;(3)

    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].

    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.

    Full Text Available 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.

It is significant to search, extract and explore the data from these vita documents which may provide a more comprehensive and integral personal profile. This personal profile can be viewed as a series of events. Moreover, we can take advantage of events from different individual's vita to explore and establish relationships between these events and the people involved. In this paper, we presented a framework extracting and explorating vita event, which can retrieve vita documents from the Internet, extract events from these documents and save the events to a database for further exploration. More concretely, the work introduced in this paper includes: (1) an event presentation model which characterizes the basic attributes of events and is utilized for event exploration; (2) a probabilistic model for extracting events from vita documents automatically; (3) an event

  5. Vita 6.2: Advanced visual tool for information management

    International Nuclear Information System (INIS)

    We have developed a knowledge management tool to search and organize disparate and large text corpora and display them in a manner for ease of interpretation. One application would be to uncover and determine the extent of clandestine nuclear supply networks. VITA, a 'Visual Interface for Text Analysis', is a tool used to direct computer-based document searches. It allows a user, via mouse and keyboard action, visually to find, organize, summarize, and present documents of potential interest. It has control features that allow visual clustering of like documents, thus enabling quick refinement of the search process. The visual features of VITA-6.2 support the observation and investigation of the [often unexpected] relationships among documents. Further, it acts to isolate and call attention to otherwise unsuspected documents of importance, in ways that other search tools cannot. The VITA series was developed first as a research testbed to identify better methods to visualize relevant document clusters and identifying their relationships. It has now stabilized into a pre-competitive design, through the interest of users in IAEA and the Government of Canada. VITA sits between the user and an extended set of search engines directed at external [Web] and internal private files The user is easily able to search and then see a conceptual map of documents, arrayed in relationships suggested by the query. The impact for knowledge discovery, summary and presentation can be surprising. The VITA output 1 arises from a nuclear proliferation query to an intelligence related website showed an unexpected outlier. On investigation, it was a highly relevant item [shown on the right] not expected, that would not have stood out nor been described among the search engine's returns in the standard lists. New in the current release VITA-x, the current version, is robust and fast, built on a Cno. platform that requires normal computing equipment and OS. Eight popular search engines are

    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

    Directory of Open Access Journals (Sweden)

    Eliopoulos, Panos

    Full Text Available Seneca expounds a theory of therapy and teaching with the ultimate goal of self knowledge and wisdom. Some of his techniques are based on Pythagorean principles or derive ideas from them, among them the focused and constant ascesis of self control. Iamblichus in De Vita Pythagorica exhibits great interest on the fact that man’s inherent abilities along with the aid of proper education suffice for his attainment of wisdom. For both thinkers, knowledge through practice is considered to be one of the major philosophical demands in the perspective of an “ars vitae”. The human being has to canalize himself into the modeling of a new way of living, an “art of living” which will contribute decisively to the fulfillment of his teleology, to his perpetual eudaimonia (bene vivere. The admittance of individual differences in people’s ability to reform themselves only signifies the more intense effort of the teacher towards a purification of their intellect and greater engagement of the individuals’ volition but not their inability for correction.

    Biological materials immersed in vegetable and mineral oil, such as rattan armor and wooden sleepers, have been extensively used since ancient times because of their excellent mechanical properties. This study quantitatively investigated the viscoelasticity and tribological performance of lignum vitae immersed in poly-alpha-olefin (PAO) and tung oils (Aleuritesfordii Hemsl.) to reveal the mechanism of impact resistance. The acceleration of samples immersed in tung oil was higher than that of dry and PAO-immersed samples in the first impact. The elastic modulus of the samples immersed in tung oil increased slightly. The impact damage on the samples immersed in tung oil was reduced because of the low friction coefficient (0.07) resulted in a low wear rate. The extent of impact damage on the samples immersed in tung oil was approximately 34% and 58% lower than that on the dry and PAO oil-immersed samples, respectively, under an angle of 20° and a height of 10 cm. The impact damage on the PAO-immersed samples was reduced because of low friction coefficient. However, impact damage increased because of large elastic modulus. The findings of this study can serve as a reference for the application of modified biological materials with high strength and wear resistance. PMID:27425829

    Full Text Available Simon Stevin has recently enjoyed a renewed interest. Long considered as mainly an engineer and a mathematician, he also earned fame for having been military advisor to Stadtholder Maurice of Nassau during almost 20 years. His lasting reputation as a scientist was due to his outstanding theoretical works (in algebra, physics, calculation of interest, linguistics, architecture, music theory, etc. and to his highly innovative technological achievements in various fields: sluices, mills, fortification, navigation, etc. But new aspects of his work have been brought to light, concerning among others his political thought. The short discourse written in Dutch and published in Leiden in 1590, Vita politica. Het Burgherlick Leven, proves to be a very original political treatise. Stevin here distances himself from both the 'mirrors-for-princes' literary genre and the humanists' claim on a privileged relationship with the supreme political power, asserting instead the capability of any citizen to make a statement on politics. In addition, he deals with the question of civic life as a practical issue.

    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).

  8. Effective Design and Evaluation of Serious Games: The Case of the e-VITA Project

    Science.gov (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.

    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.

    Full Text Available Il saggio prende spunto da due romanzi-campione, L'educazione sentimentale di Flaubert e Lolita di Nabokov, per sviluppare una riflessione sulle trame del desiderio e dell'amore nella modernità borghese. Il quadro teorico di riferimento è il rapporto tra letteratura ed esperienza, tra la percezione del mondo e la sua trascrizione nel linguaggio, con riferimento specifico a una delle esperienze fondamentali della vita umana, la passione amorosa. Il saggio intreccia riflessioni di tipo tematico con un'analisi minuziosa degli aspetti stilistico-formali.

    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.

    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.

    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.

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

    Directory of Open Access Journals (Sweden)

    Gert J. Steyn

    2013-06-01

    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. Dit het verder ten doel om vas te stel tot watter mate hierdie denke sy beskrywing van die God van Israel se wêreld, waarbinne die Moses-vertelling ontvou, beïnvloed het. Gegewe die feit dat Philo ’n teoloog par excellence is, kan die vraag gevra word of Philo se benadering nader is aan wat ’n mens ’n ‘teologiese kosmologie’ kan noem, of eerder nader aan ’n ‘kosmologiese teologie’ is? Na ’n kort oorsig oor Philo se neiging om die

    Full Text Available The use of hemoglobin-based oxygen carriers (HBOC as oxygen delivering therapies during hypoxic states has been hindered by vasoconstrictive side effects caused by depletion of nitric oxide (NO. OxyVita C is a promising oxygen-carrying solution that consists of a zero-linked hemoglobin polymer with a high molecular weight (~17 MDa. The large molecular weight is believed to prevent extravasation and limit NO scavenging and vasoconstriction. The aim of this study was to assess vasoactive effects of OxyVita C on systemic blood pressures and cerebral pial arteriole diameters. Anesthetized healthy rats received four intravenous (IV infusions of an increasing dose of OxyVita C (2, 25, 50, 100 mg/kg and hemodynamic parameters and pial arteriolar diameters were measured pre- and post-infusion. Normal saline was used as a volume-matched control. Systemic blood pressures increased (P ≤ 0.05 with increasing doses of OxyVita C, but not with saline. There was no vasoconstriction in small (<50 µm and medium-sized (50–100 µm pial arterioles in the OxyVita C group. In contrast, small and medium-sized pial arterioles vasoconstricted in the control group. Compared to saline, OxyVita C showed no cerebral vasoconstriction after any of the four doses evaluated in this rat model despite increases in blood pressure.

    Full Text Available Victor van Vita het geglo dat die Vandale se vervolging van die Christene in Noord-Afrika (429–489 n.C. ’n straf van God was. Die Christene in Noord-Afrika was volgens hom immoreel en het losbandige lewens gelei. Lyding of marteling is hiervolgens ’n natuurlike resultaat van die mens se sonde. Victor verklaar in Pauliniese konteks dat die sondige liggaam deur middel van marteling vernietig word en dat die mens nie meer slaaf van die sonde sal wees nie. Victor wil dus die persepsie by die leser tuisbring dat marteling ’n goddelike en verlossende kwaliteit behels. Die uitbeelding van die martelaars se leefwyse moet die leser aanspoor om hulle dade na te streef. Hieromtrent bied die martelaarverhale ’n vierledige funksie vir die handhawing van morele waardes in die burgerlike samelewing. Dié funksies vergestalt die etiese, eksemplariese, filosofiese en aansporende dimensies van die martelaarsverhale in die Historia Persecutionis. Op grond hiervan is die martelaarsverhale in die Historia Persecutionis nie net as ’n literêre werk nie, maar dra dit ook by tot onderrig in die sedeleer.The functionality of the martyrs’ accounts in Victor of Vita’s Historia Persecutionis (HP. Victor of Vita believed that the Vandal persecution of the Christians in North Africa (429–489 AD was a visitation of God to punish them for their immoral and dissolute life. In this context, suffering and torture are the logical results of profligacy which Victor explains in Paulinian terms as a means of destroying the human body and thus releasing mankind from bondage to sin. Victor therefore advances arguments to convince the reader that torture contains both divine and redeeming qualities. The life of the martyr is portrayed as an encouragement so that the reader may emulate this conduct. The martyr narratives provide four measures for the preservation of moral values in civil society. They embody the ethical, exemplary, philosophical and stimulant dimensions

    The care of patients with end-stage renal disease has been evolving since the implementation of the Medicare entitlement for ESRD in 1973. Over the past 43 years, patients with ESRD have become increasingly complex with multiple comorbid conditions and the average age of new ESRD patients has continued to climb. Despite these challenges, progress has been made in improving mortality and morbidity, but the pace has generally been slow. The consolidation of the US dialysis industry has afforded large providers to achieve economies of scale and efficiencies. By reinvesting resources in innovative programs, the improvements in outcomes have accelerated. At DaVita, we have reimagined care for our ESRD patients by creating a Patient-Focused Quality Pyramid, an approach to holistic, patient-centered care that builds on the foundation of well-known dialysis metrics like adequacy and anemia management to drive more complex programs like fluid, medication, diabetes, and infection management. The ultimate goal is to improve survival, keep patients healthy and out of the hospital, enhance the patient experience of care, and thereby achieve optimal health-related quality of life. For two consecutive years, DaVita facilities, using this approach, have achieved superior performance in the CMS 5-Star rating program, most recently with 46% of facilities achieving 4 or 5 stars compared with only 23% of facilities outside of DaVita receiving 4 or 5 stars. This rating system has components of fundamentals, and more complex outcomes and our results are an external validation of the success of our approach in improving the lives of patients.

    Jonathan Osborne's positive views on the current GCSE science curricula for 14-16 year olds in England, Wales and Northern Ireland (June p20) fail to impress, given that whatever we are preparing now will be replaced in a few years' time. The last syllabus, for example, lasted just six years. I agree that it will take several years before most science teachers are fully competent to teach the present curriculum; it is a shame, therefore, that a small group of non-scientists are probably already planning the next one.

The general features of the Au+Au pseudorapidity distributions results will be discussed and compared to those of /line{p}p collisions. The total charged particle multiplicity, scaled by the number of participant pairs, is observed to be about 40% higher in Au+Au collisions than in /line{p}p and d+Au systems, but, surprisingly at the same level of e+e- collisions. Limiting fragmentation scaling is seen to be obeyed in Au+Au collisions.

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.

    discussed in this article refer to “bottom up” solutions to tackle climate change in which the transport sector bears a heavy responsibility.
    These reports have all the same target - the urgency to respond to global climate change in urban centers-  but different methodology to test how and how much is the commitment of govern and people to meet this challenge.
    What stands out is the awareness that current lifestyles must necessarily change in order to assure vivibility to the future generations.
    This article attempts to stimulate the attention of the scientific field about the possibilities that an in-depth study dealing with signals of changement may have.

    L’articolo propone una riflessione sulla necessità di un approfondimento scientifico sulle prospettive di cambiamento necessarie a qualsiasi modello di sostenibilità.

    Nello scenario attuale, la prospettiva della sostenibilità, infatti, sembra sempre più orientata a modificare o quantomeno a mettere in discussione gli attuali modelli di crescita socioeconomica.

    A voler sintetizzare all’estremo, si tratta di prendere coscienza del fatto che gli attuali stili di vita debbano necessariamente modificarsi, se realmente si vuole tentare di ammortizzare gli effetti dell’irresponsabile gestione del territorio e delle città sulle generazioni che seguiranno la nostra.

    Since 2000, thousands of young Filipino migrants have come to Denmark as au pairs. Officially, they are there to “broaden their cultural horizons” by living temporarily with a Danish host family, but they also conduct domestic labor in exchange for food and money, which allows them to send...... ethnographic component of the dissertation consists of four articles, all emphasizing the au pairs’ agency by viewing their migration as a dynamic personal and social experience. Arguing that Filipina au pairs tend to be understood primarily from the perspective of their precarious situation as domestic...... of their Danish host families. Based on their migratory status as au pairs, these young migrants must therefore negotiate the different moral and contractual rights and obligations that characterize the local and transnational family ties in which they are engaged.

    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.

    The Vienna Transdanube Aging (VITA) study searches for early markers of Alzheimer's disease (AD) by examining the mental status in a community-based cohort of 606, 75-years old volunteers that are then related to various clinical and genetic analyses. To determine whether mutations in mtDNA are involved in expression of AD, the mtDNA of 79 "control" participants is screened for alterations by sequencing of "hot-spot-regions". This study on mtDNA mutations has eliminated the influence of aging on the occurrence of mtDNA alterations by sequencing samples from persons at the age of exactly 75 years. Thus, our cohort reveals a snap-shot of mitochondrial sequences of elderly persons. So far, a high percentage (56%) of persons with known or unknown mutations in the fragments analyzed were found. These data will be compared in due time to a cohort of participants with proven late-onset AD. PMID:15338331

    @@ What makes a coherent EFL curriculum? How can curriculum planners avoid a mismatch between policy and pragmatics to produce an effective decision-making process? In The Second Language Curriculum, Johnson describes the coherent curriculum as one in which decision outcomes from the various stages of development are mutually consistent and complementary,and learning outcomes reflect curriculum aims.The achievement of coherence is said to depend crucially in most educational contexts upon the formalisation of decision-making processes and products. This formalisation facilitates consensus among those involved and is a prerequisite for effective evaluation and subsequent renewal (1994: xiii)

    Full Text Available Background. Secondo l’Organizzazione Mondiale della Sanità la qualità di vita (QdV è “la personale percezione che un individuo ha della propria posizione nella vita, nel contesto di una cultura e di un insieme di valori nei quali egli vive, anche in relazione ai propri obiettivi, aspettative e preoccupazioni”. Numerosi sono gli strumenti psicometrici progettati per misurare in ambito sanitario l’impatto dell’erogazione di interventi clinico-assistenziali sulla QdV degli utenti, tuttavia poca attenzione si è posta sul ruolo di alcuni predittori - socio-demografici, clinici ed economico-sanitari - durante la degenza ospedaliera. Obiettivi. Accertare l’esistenza ed il tipo di associazione tra alcuni predittori e la variazione della QdV alla dimissione; esaminare i possibili risvolti per la pratica infermieristica. Metodi. Lo studio, condotto presso la struttura ospedaliera del polo universitario di Milano, ha somministrato all’ingresso e alla dimissione dei pazienti lo strumento psicometrico EuroQol-5D. Per valutare l’impatto del trattamento sulla QdV è utilizzato il test ?2, mentre per misurare significatività e rilevanza dei predittori è stato creato un modello di regressione logistica multipla. Risultati. L’erogazione di un trattamento clinico durante il ricovero migliora la QdV percepita (p < 0.001. La proporzione di esiti positivi nei trattamenti medici rispetto a quelli chirurgici è superiore (p < 0.05, così come quella nei ricoveri urgenti (p < 0.01. Il modello di regressione logistica multipla mostra associazioni significative tra età (p < 0.05, degenza (p < 0.05, tempo di intervento (p < 0.01 e variazione della QdV. Limiti.

    The magnetic susceptibility of liquid Cr-Au, Mn-Au, Fe-Au and Cu-Au alloys was investigated as a function of temperature and composition. Liquid Cr{sub 1-c}Au{sub c} with 0.5 ≤ c and Mn{sub 1-c}Au{sub c} with 0.3≤c obeyed the Curie-Weiss law with regard to their dependence of χ on temperature. The magnetic susceptibilities of liquid Fe-Au alloys also exhibited Curie-Weiss behavior with a reasonable value for the effective number of Bohr magneton. On the Au-rich side, the composition dependence of χ for liquid TM-Au (TM=Cr, Mn, Fe) alloys increased rapidly with increasing TM content, respectively. Additionally, the composition dependences of χ for liquid Cr-Au, Mn-Au, and Fe-Au alloys had maxima at compositions of 50 at% Cr, 70 at% Mn, and 85 at% Fe, respectively. We compared the composition dependences of χ{sub 3d} due to 3d electrons for liquid binary TM-M (M=Au, Al, Si, Sb), and investigated the relationship between χ{sub 3d} and E{sub F} in liquid binary TM-M alloys at a composition of 50 at% TM.

    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.

    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 (www.heartonline.org.au) and HeartOne (www.heartone.com.au). 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.

Three different types of nanostructures were fabricated: nanopillars, nanorings and nanonuggets. The nanopillars are the basic structures and are 50 nm in diameter and 100 nm in height. Particular arrangement of the nanopillars in various geometries formed nanorings and nanonuggets. Flat surfaces, rough substrate surfaces, and various nanostructured surfaces were compared for their abilities to attach and kill bacterial cells. Methicillin-resistant Staphylococcus aureus, a Gram-positive bacterial strain responsible for many infections in health care system, was used as the model bacterial strain. It was found that all the Au nanostructures, regardless their shapes, exhibited similar excellent antibacterial properties.

    The magnetic susceptibility of liquid Cr-Au, Mn-Au, Fe-Au and Cu-Au alloys was investigated as a function of temperature and composition. Liquid Cr1-cAuc with 0.5 ≤ c and Mn1-cAuc with 0.3≤c obeyed the Curie-Weiss law with regard to their dependence of χ on temperature. The magnetic susceptibilities of liquid Fe-Au alloys also exhibited Curie-Weiss behavior with a reasonable value for the effective number of Bohr magneton. On the Au-rich side, the composition dependence of χ for liquid TM-Au (TM=Cr, Mn, Fe) alloys increased rapidly with increasing TM content, respectively. Additionally, the composition dependences of χ for liquid Cr-Au, Mn-Au, and Fe-Au alloys had maxima at compositions of 50 at% Cr, 70 at% Mn, and 85 at% Fe, respectively. We compared the composition dependences of χ3d due to 3d electrons for liquid binary TM-M (M=Au, Al, Si, Sb), and investigated the relationship between χ3d and EF in liquid binary TM-M alloys at a composition of 50 at% TM.

  13. Meaning from curriculum analysis

    Science.gov (United States)

    Finegold, Menahem; Mackeracher, Dorothy

    This paper reports on the analysis of science curricula carried out across Canada within the framework of the Second International Science Study (SISS). The organization of Canadian education in twelve autonomous educational jurisdictions is briefly described and problems are noted in relation to the analysis of curricula on a national scale. The international design for curriculum analysis is discussed and an alternative design, more suited to the diversity of science education in Canada, is introduced. The analysis of curriculum documents is described and three patterns which emerge from this analysis are identified. These derive from the concepts of commonality, specificity and prescriptiveness. Commonality relates to topics listed in curriculum guideline documents by a number of jurisdictions. Specificity refers to the richness of curriculum documents. Prescriptiveness is a measure of the extent to which jurisdictions do or do not make provision for local options in curriculum design. The Canadian analysis, using the concepts of the common curriculum, specificity and prescriptiveness, is described and research procedures are exemplified. Outcomes of curriculum analysis are presented in graphical form.

    Full Text Available Abstract The use of nanowires (NWs for labeling, sensing, and sorting is the basis of detecting biomolecules attached on NWs by optical and magnetic properties. In spite of many advantages, the use of biomolecules-attached NWs sensing by photoelectrochemical (PEC study is almost non-existent. In this article, the PEC study of dye-attached single-stranded DNA on Au NWs and Au-Ni-Au multilayer NWs prepared by pulse electrodeposition are investigated. Owing to quantum-quenching effect, the multilayer Au NWs exhibit low optical absorbance when compared with Au NWs. The tagged Au NWs show good fluorescence (emission at 570 nm, indicating significant improvement in the reflectivity. Optimum results obtained for tagged Au NWs attached on functionalized carbon electrodes and its PEC behavior is also presented. A twofold enhancement in photocurrent is observed with an average dark current of 10 μA for Au NWs coated on functionalized sensing electrode. The importance of these PEC and optical studies provides an inexpensive and facile processing platform for Au NWs that may be suitable for biolabeling applications.

    Full Text Available The change towards the information society implies that many countries have to change their curricula, because students need to develop competencies that are not addressed in the traditional curricula. A case study approach was applied to examine curriculum changes in ICT-supported pedagogical practices from 28 countries. The analysis focused on curriculum content and goals of the ICT-supported pedagogical practices, how these aims were implemented in practice and which outcomes for students and teachers could be observed. The results showed that the curriculum content often was not new but rather was delivered in a different way. Many ICT-supported pedagogical practices strove to realize new goals important for lifelong learning in an information society. Content and goals were offered in curricular settings, often crossing the traditional boundaries of academic subjects. In many of the cases students worked on topics that were meaningful to them.

    2003-01-01

    Au-Zr binary system was reassessed by using the calculation phase diagram (CALPHAD) technique based on experimental thermodynamic data and newly reported phase diagrams. The excess Gibbs energies of the three terminal solutions and the liquid phases were formulated with Redlich-Kister polynomial. All the intermetallic phases were treated as stoichiometric compounds with the exception of ZrAu which is modeled by a two-sublattice model, (Au,Zr) : (Au, Zr). The results show that there exist seven intermetallics: Zr3Au, Zr2Au, Zr5Au4,Zr7Au10, ZrAu2 , ZrAu3, and ZrAu4 in the system. The eutectoid reaction: β(Zr) →α(Zr)+Zr3Au takes place at 1 048 K and the maximal solubility of Au in α-Zr is 4.7 % (mole fraction). The maximal solubility of Zr in Au is 6.0%(mole fraction) at 1 347 K. The homogeneity range of ZrAu phase is about 44.5%-52.9%(mole fraction) of Au. The present assessment fits experimental data very well.

    The change in surface roughness after different surface finishing techniques has attracted the attention of several prosthodontists regarding wear of opposing teeth or restorative material and the strength; plaque retention and appearance of the restoration. However, there is considerable controversy concerning the best methods to achieve the smoothest and strongest porcelain restorations after chair side clinical adjustments. The purpose of this in vitro study was to compare the average surface roughness of a self-glazed surface, a chair side polished surface and a reglazed surface of ceramic. Two feldspathic porcelain, namely VITA VMK94 (Vita Zahnfabrik, Bad Sachingen, Germany) and IVOCLAR CLASSIC (Vivadent AG, FL-9494 Schaan, Liechtenstein) were selected to fabricate 20 specimens of each in the shape of shade guide tabs. A medium-grit diamond rotary cutting instrument was used to remove the glaze layer, and then the surface of half the specimens were re-glazed and the other half were polished using a well-defined sequence of polishing comprising of: Shofu porcelain polishing system, White gloss disc/polishing wheel, Silicone cone with diamond polishing paste and finally with small buff wheel with pumice slurry. The surface roughness (Ra) (μm) of the specimens was evaluated using a profilometer and scanning electron microscope. The data were statistically analyzed by using Student's t test. The results had shown that there is no statistically significant difference both quantitatively and qualitatively, between the surface roughness of reglazed and chair-side polished surface. In addition, both reglazed and chair-side polished surfaces are better than the autoglazed surface. Within all the groups, there is no significant difference between companies. Polishing an adjusted porcelain surface with the suggested sequence of polishing will lead to a finish similar to a re-glazed surface. Therefore chair-side polishing can be a good alternative to reglazing for

The students transfer to lower secondary school at the age of 10-13, with the youngest entrants found in Germany and Austria and the oldest ones, being at the age of 16, in the Nordic countries. The most thoroughly school-based vocational upper secondary education is provided in Finland, Sweden, Spain, Greece and Portugal. The highest proportion of vocational training delivered at the workplace is to be found in Austria (a little less than half and the Netherlands (a third, that of training combining the workplace and school in Denmark, Germany, France and the Netherlands. Curriculum denotes the formal specification of what is taught and learnt in educational or training establishments. Curricula are formally specified in such learning and teaching entities as units, courses, clusters, sequences and other specifications. Levels of curricula vary from national to student ones, and types of curricula differ from intended to learned syllabi. The traditions of curriculum vary according to national contexts and to historical periods. Curriculum development in TVET is approached from a broad technological knowledge, activity-oriented theories of learning and from the concept of vocation (Beruf. Ethics of sustainable development gives a global and future perspective to education and training. The first two chapters illustrate the global, regional and national policy context of curriculum in TVET followed by a historical discussion about a curriculum theory and didactics. Then the learning theories focus on work-based learning issues and an activity approach. Next the ethics and implementation of education for sustainable development is analysed. Finally a window to the future is opened by a national practice of workforce anticipation.

    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.

  16. Curriculum: Foreign language learning

    OpenAIRE

    Lin, AMY

    2010-01-01

    This article presents an overview of various issues related to curriculum in foreign language learning, and in particular focuses on learning English as a foreign language (EFL). Foreign language learning is taken to mean the learning of a language other than the learner’s first language (L1), and this language is not ordinarily used in the learner’s everyday life. Thus, foreign language learning contexts are very different from second language learning contexts, for in second language learni...

  17. Multiscale Modeling of Au-Island Ripening on Au(100

    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.

    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...... with a discussion of why it is important to understand and take into account teacher agency, when formulating and developing curriculum policy....

  19. Relative Distribution of Au48+ ~ Au52+ in Au Plasma by Ionization Dynamics

    The present work proposes a theoretical method called ionization dynamics to derive the ionic charge state distribution. Using relativistic quantum mechanics to calculate the energy level lifetime and average ionic lifetime of each ion, the first-order ionization rate constant can be obtained. Based on these data, from the solution of differential equations for consecutive-irreversible ionization reactions, one will be able to derive the ionic charge state distribution.The calculated average positive charge 49.24 of Au48+ ~ Au52+ and their relative distribution are in good agreement with the results of Lawrence Livermore National Laboratory.

    Ibarra, D. L.

    2015-12-01

    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

  2. Biology Reflective Assessment Curriculum

    Science.gov (United States)

    Bayley, Cheryl Ann

    Often students and educators view assessments as an obligation and finality for a unit. In the current climate of high-stakes testing and accountability, the balance of time, resources and emphasis on students' scores related to assessment have been slanted considerably toward the summative side. This tension between assessment for accountability and assessment to inform teaching strains instruction and educators' ability to use that information to design learning opportunities that help students develop deeper conceptual understanding. A substantive body of research indicates that formative and reflective assessment can significantly improve student learning. Biology Reflective Assessment Curriculum (BRAC) examines support provided for high school science students through assessment practices. This investigation incorporates the usage of reflective assessments as a guiding practice for differentiated instruction and student choice. Reflective assessment is a metacognitive strategy that promotes self-monitoring and evaluation. The goals of the curriculum are to promote self-efficacy and conceptual understanding in students learning biology through developing their metacognitive awareness. BRAC was implemented in a high school biology classroom. Data from assessments, metacognitive surveys, self-efficacy surveys, reflective journals, student work, a culminating task and field notes were used to evaluate the effectiveness of the curriculum. The results suggest that students who develop their metacognitive skills developed a deeper conceptual understanding and improved feelings of self-efficacy when they were engaged in a reflective assessment unit embedded with student choice. BRAC is a tool for teachers to use assessments to assist students in becoming metacognitive and to guide student choice in learning opportunities.

    The system created in non-central relativistic nucleus-nucleus collisions possesses large orbital angular momentum. Due to spin-orbit coupling, particles produced in such a system could become globally polarized along the direction of the system angular momentum. We present the results of Lambda and anti-Lambda hyperon global polarization measurements in Au+Au collisions at sqrt{s_NN}=62.4 GeV and 200 GeV performed with the STAR detector at RHIC. The observed global polarization of Lambda and anti-Lambda hyperons in the STAR acceptance is consistent with zero within the precision of the measurements. The obtained upper limit, |P_{Lambda,anti-Lambda}| <= 0.02, is compared to the theoretical values discussed recently in the literature.

    Using the FOPI detector at GSI Darmstadt, excitation functions of collective flow components were measured for the Au+Au system, in the reaction plane and out of this plane, at seven incident energies ranging from 100AMeV to 800AMeV. The threshold energies, corresponding to the onset of sideward-flow (balance energy) and squeeze-out effect (transition energy), are extracted from extrapolations of these excitation functions toward lower beam energies for charged products with Z>2. The transition energy is found to be larger than the balance energy. The impact parameter dependence of both balance and transition energies, when extrapolated to central collisions, suggests comparable although slightly higher values than the threshold energy for the radial flow. The relevant parameter seems to be the energy deposited into the system in order to overcome the attractive nuclear forces.

  5. Charge fluctuations in Au+Au collisions at RHIC energy

    A hadron and string cascade model, JPCIAE, together with the corresponding Monte Carlo eventgenerator, has been employed in this paper to investigate further the charge fluctuations in Au+Au collisions at√Snn= 130 GeV. The default JPCIAE calculations are in good agreement with PHENIX and STAR data. Wefound that the thermal predictions for the π gas, the resonance π gas and quark matter deviate, respectively,from the corresponding dynamical simulations from the JPCIAE model. The discrepancies were also foundbetween the π charge fluctuations and the charge fluctuations of all species of hadrons. However the chargefluctuations for "π from ρ and ω decay" and for all the hadrons from resonance decay are close to each other,indicating the correlation between positively and negatively charged hadrons is not sensitive to the species ofhadrons. This work shows further that it is questionable to use the charge fluctuations as a signature of QGP.

  6. Nuclear Modification of Jet Fragmentation in Au+Au Collisions

    2015-10-01

    The characterization of energy in the quark gluon plasma is facilitated by measurements of modifications to the observed jet fragmentation. A favorable channel of study relies on direct photons created in the initial parton interactions of heavy ion collisions. Such a photon traverses the created medium unscathed and grants us a proxy for the transverse momentum of an away side jet. PHENIX Au+Au data recorded at √{sNN} = 200 GeV during RHIC run 14 benefit from the background rejection capability of the silicon vertex detector, enabling the extraction of a higher purity hadron signal. This advantage, combined with a larger integrated luminosity, allows previous PHENIX measurements of fragmentation functions to be extended to greater jet energies. In this talk, the status of the analysis of direct photon hadron correlations with the new data set will be discussed.

    We studied the use, uptake, and effects of e-Vita, a personal health record, with self-management support and personalized asynchronized coaching, for type 2 diabetes patients treated in primary care. Patients were invited by their practice nurse to join the study aimed at testing use and effects of a personal health record. Patients were followed up for 6 months. Uptake and usage were monitored using log data. Outcomes were self-reported diabetes self-care, diabetes-related distress, and emotional wellbeing. Patients' health status was collected from their medical chart. 132 patients agreed to participate in the study of which less than half (46.1%) did not return to the personal health record after 1st login. Only 5 patients used the self-management support program within the personal health record, 3 of whom asked a coach for feedback. Low use of the personal health record was registered. No statistical significant differences on any of the outcome measures were found between baseline and 6 month follow-up. This study showed minimal impact of implementing a personal health record including self-management support in primary diabetes care. Successful adoption of web-based platforms, as ongoing patient centered care, is hard to achieve without additional strategies aimed at enhancing patient motivation and engaging professionals.

    In the presence of 0.5 millimolar allopurinol (4-hydroxypyrazolo (3,4-d)pyrimidine), an inhibitor of NAD:xanthine oxidoreductase (EC 1.2.3.2), intact attached nodules of cowpea (vigna unguiculata L. Walp. cv Vita 3) formed (/sup 15/N)xanthine from /sup 15/N/sub 2/ at rates equivalent to those of ureide synthesis, confirming the direct assimilation of fixed nitrogen into purines. Xanthine accumulated in nodules and was exported in increasing amounts in xylem of allopurinol-treated plants. Other intermediates of purine oxidation, de novo purine synthesis, and ammonia assimilation did not increase and, over the time course of experiments (4 hours), allopurinol had no effect on nitrogenase (EC 1.87.99.2) activity. Negligible /sup 15/N -labeling of asparagine from /sup 15/N/sub 2/ was observed, suggesting that the significant pool (up to 14 micromoles per gram of nodule fresh weight) of this amide in cowpea nodules was not formed directly from fixation but may have accumulated as a consequence of phloem delivery.

    2015-10-28

    Coronary artery calcification (CAC) develops early in the pathogenesis of atherosclerosis and is a strong and independent predictor of cardiovascular disease (CVD). Arterial calcification is caused by an imbalance in calcification regulatory mechanisms. An important inhibitor of calcification is vitamin K-dependent matrix Gla protein (MGP). Both preclinical and clinical studies have shown that inhibition of the vitamin K-cycle by vitamin K antagonists (VKA) results in elevated uncarboxylated MGP (ucMGP) and subsequently in extensive arterial calcification. This led us to hypothesize that vitamin K supplementation may slow down the progression of calcification. To test this, we designed the VitaK-CAC trial which analyses effects of menaquinone-7 (MK-7) supplementation on progression of CAC. The trial is a double-blind, randomized, placebo-controlled trial including patients with coronary artery disease (CAD). Patients with a baseline Agatston CAC-score between 50 and 400 will be randomized to an intervention-group (360 microgram MK-7) or a placebo group. Treatment duration will be 24 months. The primary endpoint is the difference in CAC-score progression between both groups. Secondary endpoints include changes in arterial structure and function, and associations with biomarkers. We hypothesize that treatment with MK-7 will slow down or arrest the progression of CAC and that this trial may lead to a treatment option for vascular calcification and subsequent CVD.

  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.

    2012-09-01

    Full Text Available Curriculum is a set of planned tasks, learning experiences and behaviors proposed by an authority to achieve predetermined goals in form of behavioral change, academic achievements and learning outcomes within a particular time. The scholars are the people who have command and expertise in any of the curriculum components. The article focuses on the role of curriculum scholars in Pakistan and how and what type of changes they can initiate to bring harmony and tolerance, character and quality in development of curricula. The international issues, trends evolving globalization can be enhanced and incorporated to foster individual and social development. It is a qualitative study based on historical evidences and current researches highlighting the importance and role of curriculum scholars and meeting the world class education system. The issues and trends mentioned by developed countries curriculum experts paved way to synthesis them with local rising issues and trends.The study concluded that the curriculum developers have dynamic roles in curriculum debates because they have to work for bridging gaps of developing and developed nation, addressing local curriculum issues, Using pragmatic approach rather than ideological, reorganizing of recent curricula, solving language issue, facing controversies on curriculum change, making it unified and centralized, diverting curricula to research orientation, obtaining continuous feedback and developing harmony in society at the same time. It is imperative for scholars to have effective communication skills and dynamic personality to incorporate the future trends without creating conflicts and confusion in the society. They need to know the skill to motivate and mould high ups for future changes and bring changes without development of controversies.

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

    KAUST Repository

    Huang, Jianfeng

    2015-08-13

    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.

    2012-10-01

    Full Text Available During the past ten years expertise in human-computer interaction has shifted from humans interacting with desktop computers to individual human beings or groups of human beings interacting with embedded or mobile technology. Thus, humans are not only interacting with computers but with technology. Obviously, this shift should be reflected in how we educate human-technology interaction (HTI experts today and in the future. We tackle this educational challenge first by analysing current Master’s-level education in collaboration with two universities and second, discussing postgraduate education in the international context. As a result, we identified core studies that should be included in the HTI curriculum. Furthermore, we discuss some practical challenges and new directions for international HTI education.

    Full Text Available Abstract Background Vitamin D does not only regulate calcium homeostasis but also plays an important role as an immune modulator. It influences the immune system through the induction of immune shifts and regulatory cells resulting in immunologic tolerance. As such, vitamin D is thought to exert beneficial effects within the transplant setting, especially in kidney transplant recipients, considering the high prevalence of vitamin D deficiency in kidney transplant recipients. Methods/Design The VITA-D study, a randomized, placebo-controlled, double-blind study with two parallel groups including a total of 200 kidney transplant recipients, is designed to investigate the immunomodulatory and renoprotective effects of cholecalciferol (vitamin D3 within the transplant setting. Kidney transplant recipients found to have vitamin D deficiency defined as 25-hydroxyvitamin D3 The objective is to evaluate the influence of vitamin D3 substitution in vitamin D deficient kidney transplant recipients on the post-transplant outcome. As a primary endpoint glomerular filtration rate calculated with the MDRD formula (modification of diet in renal disease one year after kidney transplantation will be evaluated. Incidence of acute rejection episodes, and the number and severity of infections (analyzed by means of C-reactive protein within the first year after transplantation will be monitored as well. As a secondary endpoint the influence of vitamin D3 on bone mineral density within the first year post-transplant will be assessed. Three DXA analyses will be performed, one within the first four weeks post-transplant, one five months and one twelve months after kidney transplantation.

    A novel interfacial route has been developed for the synthesis of a bright-red-emitting new subnanocluster, Au(23), by the core etching of a widely explored and more stable cluster, Au(25)SG(18) (in which SG is glutathione thiolate). A slight modification of this procedure results in the formation of two other known subnanoclusters, Au(22) and Au(33). Whereas Au(22) and Au(23) are water soluble and brightly fluorescent with quantum yields of 2.5 and 1.3 %, respectively, Au(33) is organic soluble and less fluorescent, with a quantum yield of 0.1 %. Au(23) exhibits quenching of fluorescence selectively in the presence of Cu(2+) ions and it can therefore be used as a metal-ion sensor. Aqueous- to organic-phase transfer of Au(23) has been carried out with fluorescence enhancement. Solvent dependency on the fluorescence of Au(23) before and after phase transfer has been studied extensively and the quantum yield of the cluster varies with the solvent used. The temperature response of Au(23) emission has been demonstrated. The inherent fluorescence of Au(23) was used for imaging human hepatoma cells by employing the avidin-biotin interaction.

    We study within the IP-Glasma and two-component MC-Glauber models the effects of initial state geometry and fluctuations on multiplicities and eccentricities for several collision species at the Relativistic Heavy Ion Collider (RHIC). These include copper-gold (Cu+Au), gold-gold (Au+Au), and uranium-uranium (U+U) collisions. The multiplicity densities per participant pair are very similar in all systems studied. Ellipticities vary strongly between collision systems, most significantly for central collisions, while fluctuation driven odd moments vary little between systems. Event-by-event distributions of eccentricities in mid-central collisions are wider in Cu+Au relative to Au+Au and U+U systems. An anti-correlation between multiplicity and eccentricity is observed in ultra central U+U collisions which is weaker in the IP-Glasma model than the two-component MC-Glauber model. In ultra central Au+Au collisions the two models predict opposite signs for the slope of this correlation. Measurements of elliptic flo...

    Directory of Open Access Journals (Sweden)

    Šaranović-Božanović Nadežda

    2002-01-01

    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.

D’autres applications sont actuellement à l’étude, car le Maroc à compris, comme tous les autres grands pays producteurs, que l’olive était un nouveau gisement de richesses.

From characteristic atom occupation (CAO) patterns of L12-Au3Cu, L12-AuCu3 and L10-AuCu compounds, their electronic structures, volumetric and energetic properties were calculated. The CAO pattern of Johasson-Linde(J-L) model shows that the transition AuCuⅠ→ AuCuⅡ is an exothermic and volume contraction reaction, which is opposite from experimental phenomena. According to CAO pattern of Guymont-Feutelais-Legendre(G-F-L) model, the AuCuⅡ cell consists of two periodic antidirection (PAD) AuCuⅠ regions and two PAD boundary regions. The equations derived from CAO pattern of G-F-L model can be used to calculate energetic properties, volumetric properties and ordering degrees of the PAD AuCul region and PAD boundary region, as well as corresponding average properties of the AuCuⅡ phase. The results are consistent with experimental phenomena.

  4. Strain distributions of confined Au/Ag and Ag/Au nanoparticles

    2015-01-01

    The strain distributions of Au/Ag and Ag/Au nanoparticles confined in the Al2O3 matrix with different core sizes are investigated by using the finite element method, respectively. The simulation results clearly indicate that the compressive strains exerted on the Au/Ag and Ag/Au nanoparticles can be induced by the Al2O3 matrix. Moreover, it can be found that the strain gradient existing in a Au/Ag nanoparticle is much larger than that in a Ag/Au nanoparticle, which could be due to the larger Young’s modulus of Au than that of Ag. With the core size increasing, the strain gradient existing in the Au/Ag nanoparticle becomes larger, while the strain gradient existing in the Ag/Au nanoparticle keeps constant. These different strain distributions may have significant infl uences on the structures and morphologies of the Au/Ag and Ag/Au nanoparticles, leading to the different physical properties for potential applications.

  5. Enhanced activity for supported Au clusters: Methanol oxidation on Au/TiO2(110)

    Tenney, Samuel A.; Cagg, Brett A.; Levine, Mara S.; He, Wei; Manandhar, Kedar; Chen, Donna A.

    Gold clusters supported on TiO2(110) exhibit unusual activity for the oxidation of methanol to formaldehyde. Temperature programmed desorption studies of methanol on Au clusters show that both Au and titania sites are necessary for methanol reaction. Isotopic labeling experiments with CD3OH demonstrate that reaction occurs via Osbnd H bond scission to form a methoxy intermediate. When the TiO2 surface is oxidized with 18O2 before or after Au deposition, methanol reaction produces H218O below 300 K, indicating that oxygen from titania promotes Osbnd H bond scission and is incorporated into desorbing products. XPS experiments provide additional evidence that during methanol reaction on the Au/TiO2 surface, methanol adsorption occurs on TiO2, given that the titania support becomes slightly oxidized after exposure to methanol in the presence of Au clusters. While the role of TiO2 is to dissociate the Osbnd H bond and form the reactive methoxy intermediate, the role of the Au sites is to remove hydrogen from the surface as H2, thus preventing the recombination of methoxy and hydrogen to methanol. The decrease in formaldehyde yield with increasing Au coverage above 0.25 ML suggests that reaction occurs at Au-titania interfacial sites; scanning tunneling microscopy images of various Au coverages confirm that the number of interfacial sites at the perimeter of the Au clusters decreases as the Au coverage is increased between 0.25 and 5 ML.

  6. Au, Ag and Au:Ag colloidal nanoparticles synthesized by pulsed laser ablation as SERS substrates

    Full Text Available Chemically pure colloidal suspensions of gold and silver nanoparticles were synthesized using pulsed laser ablation. The dependence of laser fluence on the surface plasmon characteristics of the nanoparticles was investigated. Au:Ag colloidal suspensions were prepared by mixing highly monodisperse Au and Ag nanocolloids. The plasmon band of these mixtures was found to be highly sensitive to Au:Ag concentration ratio and wavelength of the laser beam used in the ablation process. The Au:Ag mixture consists of almost spherical shaped nanostructures with a tendency to join with adjacent ones. The surface enhanced Raman scattering activity of the Au, Ag and Au:Ag colloidal suspensions was tested using crystal violet as probe molecules. Enhancement in Raman signal obtained with Au:Ag substrates was found to be promising and strongly depends on its plasmon characteristics.

    2007-02-01

    The phase equilibria of the Sn-Cu-Au ternary, Ag-Sn-Cu-Au quaternary systems and interfacial reactions between Sn-Cu alloys and Au were experimentally investigated at specific temperatures in this study. The experimental results indicated that there existed three ternary intermetallic compounds (IMCs) and a complete solid solubility between AuSn and Cu6Sn5 phases in the Sn-Cu-Au ternary system at 200°C. No quaternary IMC was found in the isoplethal section of the Ag-Sn-Cu-Au quaternary system. Three IMCs, AuSn, AuSn2, and AuSn4, were found in all couples. The same three IMCs and (Au,Cu)Sn/(Cu,Au)6Sn5 phases were found in all Sn-Cu/Au couples. The thickness of these reaction layers increased with increasing temperature and time. The mechanism of IMC growth can be described by using the parabolic law. In addition, when the reaction time was extended and the Cu content of the alloy was increased, the AuSn4 phase disappeared gradually. The (Au, Cu)Sn and (Cu,Au)6Sn5 layers played roles as diffusion barriers against Sn in Sn-Cu/Au reaction couple systems.

    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.

  13. A ‘Globalised’ Curriculum

    Globalisation is often referred to as being external to education – a state of affairs presenting the modern curriculum with numerous challenges. In this article, ‘globalisation’ is examined as something that is internal to curriculum and analysed as a problematisation in a Foucaultian sense......, that is, as a complex of attentions, worries and ways of reasoning, producing curricular variables. The analysis is made through an example of early childhood curriculum in Danish preschool, and the way the curricular variable of the preschool child comes into being through ‘globalisation......’ as a problematisation, carried forth by comparative practices such as Programme for International Student Assessment. It thus explores some of the systems of reason that educational comparative practices carry through time, focusing on the ways in which configurations are reproduced and transformed, forming...

    This report provides general guidelines for the structure of a curriculum, followed by specific advice on the principles of learning and teaching, the process of restructuring and change leadership and management. It provides examples of several educational philosophies, including vertical and horizontal integration. It discusses the use of competence, learning outcomes, level of degree and assessment and provides a number of recommendations. It does not seek to be prescriptive of time allocation to disciplines within a curriculum. Although this report has been written primarily for those who will develop an undergraduate curriculum, the information may be sufficiently generic to apply to the recent development in graduate entry ('shortened dental' or 'accelerated') courses and to postgraduate degree planning and higher education certificate or diploma courses for other dental care professionals (auxiliaries). The report may have a European bias as progress is made to converge and enhance educational standards in 29 countries with different educational approaches - a microcosm of global collaboration.

  11. Controlled Synthesis of Au@AgAu Yolk-Shell Cuboctahedra with Well-Defined Facets.

    Science.gov (United States)

    Londono-Calderon, Alejandra; Bahena, Daniel; Yacaman, Miguel J

    2016-08-01

    The synthesis of Au@AgAu yolk-shell cuboctahedra nanoparticles formed by galvanic replacement in a seed-mediated method is described. Initially, single-crystal Au seeds are used for the formation of Au@Ag core-shell nanocubes, which serve as the template material for the deposition of an external Au layer. The well-controlled synthesis yields the formation of cuboctahedra nanoparticles with smooth inner and outer Au/Ag surfaces. The deposition/oxidation process is described to understand the formation of cuboctahedra and octahedra nanoparticles. The Au core maintains the initial morphology of the seed and remains static at the center of the yolk-shell because of residual Ag. Structural analysis of the shell indicates intrinsic stacking faults (SFs) near the surface. Energy dispersive X-ray spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS) compositional analysis show an Au-Ag nonordered alloy forming the shell. The three-dimensional structure of the nanoparticles presented open facets on the [111] as observed by electron tomography SIRT reconstruction over a stack of high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) images. The geometrical model was validated by analyzing the direction of streaks in coherent nanobeam diffraction (NBD). The catalytic activity was evaluated using a model reaction based on the reduction of 4-nitrophenol (4-NTP) by NaBH4 in the presence of Au@AgAu yolk-shell nanoparticles. PMID:27385583

    Research highlights: > It's the first time that Au-La and Au-Er binary systems were thermodynamically assessed since 1985. > Besides, in the present work, the ab initio approach has been employed to calculate the formation enthalpies of the IMCs involved in Au-Er and Au-La binary systems, and then, by combining with all of the available experimental information, these two-system were thermodynamically optimized via CALPHAD method. Therefore, a more reliable thermodynamic description has been obtained for these systems. - Abstract: Phase relationships in Au-La and Au-Er binary systems have been thermodynamically assessed by using the CALPHAD technique. The existing thermodynamic descriptions of the systems were improved by incorporating the ab initio calculated enthalpies of formation of the intermetallic compounds, except for the Au{sub 51}La{sub 14} and Au{sub 10}Er{sub 7} phases. All the binary intermetallic compounds were treated as stoichiometric phases, while the solution phases, including liquid, fcc, bcc, and dhcp, were treated as substitutional solution phases and the excess Gibbs energies were formulated with Redlich-Kister polynomial function. As a result, two self-consist thermodynamic data sets for describing the Au-La and Au-Er binary systems were obtained.

This article argues that, despite this critique, au pairing does play an important formative role for young Filipinas because it opens up for experiences abroad that enable them to be recognised as independent adults in Philippine society. Rather than autonomy, however, au pairs define their independence...... in terms of their capacity to assume responsibility for others, thereby achieving a position of social respect. Based on ethnographic fieldwork in Denmark and the Philippines, this article explores how young Filipinas use the social, economic, and cultural resources they gain from their au pair stay abroad...

  2. 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

    2015-03-17

    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.

    2008-10-01

    BRAHMS has studied net-protons distributions in Au+Au and p+p collisions at √sNN=62.4 and 200 GeV. Net-proton distributions reflect the net-baryon yields and can be used to extract the nuclear stopping in the collisions, thus providing information on baryon number transport and energy available for particle production. The talk will present final and preliminary results from the above mentioned systems. It will be shown that in p+p and in Au+Au central collisions that net-proton distributions exhibit longitudinal scaling once the target contribution to the projectile rapidity range is corrected for. The difference between p+p and Au+Au will be discussed. Aspects of future measurements at the LHC of net-baryons at mid-rapidity will be brought forth.

  8. Studying of the photoluminescence characteristics of Au(0)@Au(I)-thiolate core–shell nanoclusters

    International Nuclear Information System (INIS)

    The photoluminescence characteristics of Au(0)@Au(I)-thiolate Core–shell nanoclusters (Au-NCs), whose size is <2 nm, are investigated. We use the time-resolved single-photon counting technique and the transient absorption technique to distinguish the mechanism of the photoluminescence of Au-NCs. The dynamic spectral data show that the photoluminescence mechanism should be composed of the fluorescence and the phosphorescence. Meanwhile, Au-NCs have the aggregation induced photoluminescence enhancement property, which is attributed to the suppression of conversion from the singlet state to triplet state when they aggregated together. In addition, the photoluminescence characteristics of aggregated Au-NCs should be further improved through infiltrating them into photonic crystals

    2003-03-01

    We present transverse momentum distributions of charged hadrons produced in Au+Au collisions at sqrt(s_NN) = 200 GeV. The evolution of the spectra for transverse momenta p_T from 0.25 to 5GeV/c is studied as a function of collision centrality over a range from 65 to 344 participating nucleons. We find a significant change of the spectral shape between proton-antiproton and peripheral Au+Au collisions. Comparing peripheral to central Au+Au collisions, we find that the yields at the highest p_T exhibit approximate scaling with the number of participating nucleons, rather than scaling with the number of binary collisions.

  15. Electrical conduction through self-assembled monolayers in molecular junctions: Au/molecules/Au versus Au/molecule/PEDOT:PSS/Au

    International Nuclear Information System (INIS)

    We fabricated and characterized a large number of octanedithiol (denoted as DC8) molecular devices as vertical metal-molecule-metal structure with or without using an intermediate conducting polymer layer of poly (3,4-ethylenedioxythiophene) stabilized with poly(4-styenesulfonic acid) (called as PEDOT:PSS). The electronic transport properties of DC8 molecular devices with and without PEDOT:PSS layer were statistically compared in terms of current density and device yield. The yields of the working molecular devices were found to be ∼ 1.75% (84 out of 4800 devices) for Au/DC8/Au junctions and ∼ 58% (74 out of 128 devices) for Au-DC8/PEDOT:PSS/Au junctions. The tunneling decay constants were obtained with the Simmons tunneling model and a multibarrier tunneling model for two kinds of molecular devices with and without PEDOT:PSS layer.

  16. Proton channeling in Au at low energies

    International Nuclear Information System (INIS)

    The electronic energy loss for low velocity protons channeled in the direction single crystal Au is calculated. The spatial distribution of valence electronic density in Au is calculated using Tight Binding Linear Muffin Tin Method. The proton trajectories are determined by numerical integration of the classical motion equation, and the energy loss is evaluated using the calculated valence electronic density in the friction term. The results allow to describe qualitatively the non linear behavior of energy loss with ion velocity observed experimentally. (author)

    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.

    Transverse momentum spectra of charged hadrons with pT 2 GeV/c). In contrast, the d + Au nuclear modification factor exhibits no suppression of the high-pT yields. These measurements suggest a large energy loss of the high-pT particles in the highly interacting medium created in the central Au + Au collisions. The lack of suppression in d + Au collisions suggests that it is unlikely that initial state effects can explain the suppression in the central Au + Au collisions. PACS: 25.75.-q

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

    2009-04-11

    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

  3. Suppression of ϒ production in d+Au and Au+Au collisions at √(sNN)=200 GeV

    International Nuclear Information System (INIS)

    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 RdAu=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 RAA=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

In contrast, polar peptide-surfaces induced a minimal change in Rct for all three proteins. Furthermore, an increase in Rct was observed with CD13 (an aminopeptidase overexpressed in certain cancers in comparison to the other proteins when the VLGXE-Au surface was modified with n-butylamine as a blocking agent. The electrochemical data indicated that protein adsorption may be modulated by tailoring the peptide sequence on Au surfaces and that blocking agents and diluents play a key role in promoting or preventing protein adsorption. The peptide-Au platform may also be used for targeting cancer biomarkers with designer peptides.

Protein adsorption onto the peptide-Au surfaces modified with the combination of n-butylamine and hexanethiol produced a dramatic decrease in the charge transfer resistance, Rct, for all three proteins. In contrast, polar peptide-surfaces induced a minimal change in Rct for all three proteins. Furthermore, an increase in Rct was observed with CD13 (an aminopeptidase overexpressed in certain cancers) in comparison to the other proteins when the VLGXE-Au surface was modified with n-butylamine as a blocking agent. The electrochemical data indicated that protein adsorption may be modulated by tailoring the peptide sequence on Au surfaces and that blocking agents and diluents play a key role in promoting or preventing protein adsorption. The peptide-Au platform may also be used for targeting cancer biomarkers with designer peptides. PMID:26262621

    Full Text Available The paper offers an overview of possibilities regarding illustrated presentations of linguistic terms, categories, principles and rules with the use of comics in Serbian language curriculum. Ways of using additional material of that kind are presented in different phases of syntax curriculum, emphasizing the importance of the application of visual means as an illustration of a variety of communication situations. Advantages of that methodological approach are stressed with respect to the realization of principles of the obvious in teaching, so selected linguistic and grammatical material was applied to sentence constructions, models and types for which we designed and developed applications in the form of representational comic supplements.

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

    Energy Technology Data Exchange (ETDEWEB)

    Hardtke, D.; STAR Collaboration

    2002-12-09

    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.

    The transverse momentum (p_T) spectra and ratios of identified charged hadrons (\\pi^+/-, K^+/-, p, p^bar) produced in sqrt(s_NN)=200 GeV Au+Au and d+Au collisions are reported in five different centrality classes for each collision species. The measurements of pions and protons are reported up to p_T=6 GeV/c (5 GeV/c), and the measurements of kaons are reported up to p_T=4 GeV/c (3.5 GeV/c) in Au+Au (d+Au) collisions. In the intermediate p_T region, between 2--5 GeV/c, a significant enhancement of baryon to meson ratios compared to those measured in p+p collisions is observed. This enhancement is present in both Au+Au and d+Au collisions, and increases as the collisions become more central. We compare a class of peripheral Au+Au collisions with a class of central d+Au collisions which have a comparable number of participating nucleons and binary nucleon-nucleon collisions. The p_T dependent particle ratios for these classes display a remarkable similarity, which is then discussed.

    The transverse momentum (pT) spectra and ratios of identified charged hadrons (π±, K±, p, p¯) produced in sNN=200 GeV Au+Au and d+Au collisions are reported in five different centrality classes for each collision species. The measurements of pions and protons are reported up to pT=6 GeV/c (5 GeV/c), and the measurements of kaons are reported up to pT=4 GeV/c (3.5 GeV/c) in Au+Au (d+Au) collisions. In the intermediate pT region, between 2 and 5 GeV/c, a significant enhancement of baryon-to-meson ratios compared to those measured in p+p collisions is observed. This enhancement is present in both Au+Au and d+Au collisions and increases as the collisions become more central. We compare a class of peripheral Au+Au collisions with a class of central d+Au collisions which have a comparable number of participating nucleons and binary nucleon-nucleon collisions. The pT-dependent particle ratios for these classes display a remarkable similarity, which is then discussed.

    The present work proposes a theoretical method called ionization dynamics to derive the ionic charge state distribution. Using relativistic quantum mechanics to calculate the energy level lifetime and average ionic lifetime of each ion, the first-order ionization rate constant can be obtained. Based on these data, from the solution of differential equations for consecutive-irreversible ionization reactions, one will be able to derive the ionic charge state distribution.The calculated average positive charge 49.24 of Au48+ ~ Au52+ and their relative distribution are in good agreement with the results of Lawrence Livermore National Laboratory.

    Polymerase chain reaction (PCR) is a useful technique for in vitro amplification of a DNA fragment. In this paper, a PCR procedure using Au nanoparticle (AuNP) -bound primers was systemically studied. The 5′-SH- (CH2)6-modified primers were covalently attached to the AuNP surface via Au-S bonds, and plasmid pBluescript SK was used as a template. The effects of the concentration of AuNP-bound primers, annealing temperature and PCR cycles were evaluated, respectively. The results indicate that PCR can proceed successfully under optimized condition, with either forward or reverse primers bound to the AuNP surface or with both the two primers bound to the AuNP surface. Development of PCR procedure based on AuNPs not only makes the isolation of PCR products very convenient, but also provides novel methods to prepare AuNP-bound ssDNA and nanostructured material.

    Graphene sheets decorated with Au nanodots are synthesized by deposition of Au of three different thicknesses and subsequent annealing at 400 °C. Different thicknesses of Au film for the formation of Au nanodots on graphene are measured using Rutherford backscattering spectrometry and morphology is studied using scanning electron microscopy. Raman spectroscopy indicates 3–6-fold increase in I{sub D}/I{sub G} ratio depending on the content of Au deposited on graphene. The increase in disorder in Au decorated graphene layers is explained on the basis of interaction of Au atoms with Π bonds of graphene. The splitting and blueshift in G band signifies compressive strain in Au deposited graphene. X-ray diffraction studies using synchrotron radiation source confirm compressive strain in graphene, which increases with increase of Au film thickness.

    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.

    The refractive index sensitivity of localized surface plasmon resonance sensors can be improved by placing the plasmonic metal particles on pillars instead of on a planar substrate. In this paper, a simple and versatile colloidal lithography method for the fabrication of plasmonic Au islands on top of polymer nanopillars is described. The pillar height is controlled by varying the thickness of the initial polymer film. An increased pillar height results in a blue shift of the absorption spectrum of the Au islands. This is explained by a decreased effective refractive index around the islands. For pillars higher than approximately 40 nm no further blue shift is observed, in agreement with the decay length of the electromagnetic field around the islands. Pillar-supported Au islands were also fabricated on a flexible foil, demonstrating the potential of the method described here for the fabrication of flexible plasmonic substrates. Benefits and limitations of the method and of using polymers as the pillar material are discussed.

    The ultraviolet photodissociation dynamics of the gold-rare gas atom van der Waals complexes (Au-RG, RG=Ar, Kr, and Xe) have been studied by velocity map imaging. Photofragmentation of Au-Ar and Au-Kr at several wavelengths permits extrapolation to zero of the total kinetic energy release (TKER) spectra as monitored in the Au(P23/2∘[5d106p]) fragment channel, facilitating the determination of ground state dissociation energies of D0″(Au-Ar)=149±13 cm-1 and D0″(Au-Kr)=240±19 cm-1, respectively. In the same spectral region, transitions to vibrational levels of an Ω'=1/2 state of the Au-Xe complex result in predissociation to the lower Au(P21/2∘[5d106p])+Xe(S10[5p6]) fragment channel for which TKER extrapolation yields a value of D0″(Au-Xe)=636±27 cm-1. Asymmetric line shapes for transitions to the v'=14 level of this state indicate coupling to the Au(P23/2∘[5d106p])+Xe(S10[5p6]) continuum, which allows us to refine this value to D0″(Au-Xe)=607±5 cm-1. The dissociation dynamics of this vibrational level have been studied at the level of individual isotopologues by fitting the observed excitation spectra to Fano profiles. These fits reveal a remarkable variation in the predissociation dynamics for different Au-Xe isotopologues. For Au-Ar and Au-Xe, the determined ground state dissociation energies are in good agreement with recent theoretical calculations; the agreement of the Au-Kr value with theory is less satisfactory.

    This study theoretically investigates Fano resonances and dips of an Au-SiO2-Au nanomatryoshka that is excited by a nearby electric dipole. An analytical solution of dyadic Green's functions is used to analyze the radiative and nonradiative power spectra of a radial dipole in the proximity of a nanomatryoshka. From these spectra, the plasmon modes and Fano resonances that accompany the Fano dips are identified. In addition, the scattering and absorption spectra of a nanomatryoshka that is illuminated by a plane wave are investigated to confirm these modes and Fano dips. Our results reveal that a Fano dip splits each of the dipole and quadrupole modes into bonding and anti-bonding modes. The Fano dip and resonance result from the destructive interference of the plasmon modes of the Au shell and the Au core. The Fano factors that are obtained from the nonradiative power spectra of the Au shell and the Au core of a nanomatryoshka are in accordance with those obtained from the absorption cross section spectra. Moreover, these Fano factors increase as the plasmonic coupling of the Au shell with the core increases for both dipole and quadrupole modes. PMID:24206789

  3. Ω production in p+p, Au+Au and U+U collisions at STAR

    International Nuclear Information System (INIS)

    We report STAR's high precision measurements on Ω production at mid-rapidity from √(s)=200 GeVp+p, central √(sNN)=200 GeVAu+Au, and central √(sNN)=193 GeVU+U collisions. With the significantly reduced uncertainty in p+p reference, we observe that the Ω enhancement factors at RHIC are in between SPS and LHC, while enhancement factors are systematically larger in central U+U collisions than in central Au+Au collisions. The ΩRAA is much larger than protons and pions for pT up to 4 GeV/c in central Au+Au collisions. The ratio of ΩRAA in central U+U to that in central Au+Au collisions is above unity for pT up to 6 GeV/c, which indicates coalescence/recombination to be the dominant production mechanism for Ω in these collisions for the measured pT range

    The PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) has measured omega meson production via leptonic and hadronic decay channels in p+p, d+Au, Cu+Cu, and Au+Au collisions at sqrt(s_NN) = 200 GeV. The invariant transverse momentum spectra measured in different decay modes give consistent results. Measurements in the hadronic decay channel in Cu+Cu and Au+Au collisions show that omega production has a suppression pattern at high transverse momentum, similar to that of pi^0 and eta in central collisions, but no suppression is observed in peripheral collisions. The nuclear modification factors, R_AA, are consistent in Cu+Cu and Au+Au collisions at similar numbers of participant nucleons.

    The PHENIX experiment at the Relativistic Heavy Ion Collider has measured ω meson production via leptonic and hadronic decay channels in p+p, d+Au, Cu+Cu, and Au+Au collisions at sNN = 200 GeV. The invariant transverse momentum spectra measured in different decay modes give consistent results. Measurements in the hadronic decay channel in Cu+Cu and Au+Au collisions show that ω production has a suppression pattern at high transverse momentum, similar to that of π0 and η in central collisions, but no suppression is observed in peripheral collisions. The nuclear modification factors, RAA, are consistent in Cu+Cu and Au+Au collisions at similar numbers of participant nucleons.

  7. Revisiting the S-Au(111) interaction: Static or Dynamic?

    Energy Technology Data Exchange (ETDEWEB)

    Biener, M M; Biener, J; Friend, C M

    2004-08-17

    The chemical inertness typically observed for Au does not imply a general inability to form stable bonds with non-metals but is rather a consequence of high reaction barriers. The Au-S interaction is probably the most intensively studied interaction of Au surfaces with non-metals as, for example, it plays an important role in Au ore formation, and controls the structure and dynamics of thiol-based self-assembled-monolayers (SAMs). In recent years a quite complex picture of the interaction of sulfur with Au(111) surfaces emerged, and a variety of S-induced surface structures was reported under different conditions. The majority of these structures were interpreted in terms of a static Au surface, where the positions of the Au atoms remain essentially unperturbed. Here we demonstrate that the Au(111) surface exhibits a very dynamic character upon interaction with adsorbed sulfur: low sulfur coverages modify the surface stress of the Au surface leading to lateral expansion of the surface layer; large-scale surface restructuring and incorporation of Au atoms into a growing two-dimensional AuS phase were observed with increasing sulfur coverage. These results provide new insight into the Au-S surface chemistry, and reveal the dynamic character of the Au(111) surface.

  8. Teaching Spreadsheets: Curriculum Design Principles

    CERN Document Server

    Tort, Francoise

    2010-01-01

    EuSpRIG concerns direct researchers to revisit spreadsheet education, taking into account error auditing tools, checklists, and good practices. This paper aims at elaborating principles to design a spreadsheet curriculum. It mainly focuses on two important issues. Firstly, it is necessary to establish the spreadsheet invariants to be taught, especially those concerning errors and good practices. Secondly, it is important to take into account the learners' ICT experience, and to encourage them to attitudes that foster self-learning. We suggest key principles for spreadsheet teaching, and we illustrate them with teaching guidelines.

    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...

    We have employed ab initio molecular dynamics to investigate the stability of the smallest gold cages, namely Au16 and Au17, at finite temperatures. First, we obtain the ground state structure along with at least 50 distinct isomers for both the clusters. This is followed by the finite temperature simulations of these clusters. Each cluster is maintained at 12 different temperatures for a time period of at least 150 ps. Thus, the total simulation time is of the order of 2.4 ns for each cluster. We observe that the cages are stable at least up to 850 K. Although both clusters melt around the same temperature, i.e. around 900 K, Au17 shows a peak in the heat capacity curve in contrast to the broad peak seen for Au16.

    We report the dispersion and scanning tunneling microscopy (STM) characterization of isolated Au-CdSe nanohybrids on atomically flat Au(111) through surface modifications.The top terminal groups of spacer molecules self-assembled on the surface are found critical for locking the nanohybrids into a well-separated state.The STM results indicate that both thiol and carboxylic terminals are effective in this aspect by making strong interaction with the Au portions of the nanohybrids.An argon ion sputtering technique is also proposed to clean up organic contaminants on the surface for improved STM imaging of individual Au-CdSe nanohybrids.These observations help to enrich technical approaches to dispersing individual nanostructures on the surface and provide opportunities to explore their local electroluminescent and energy transfer properties at the nanoscale.

    We report high resolution photoelectron spectra of Au_2^- and Au_4^- obtained with a newly-built photoelectron imaging apparatus. Gold anions are produced by laser vaporization and the desired specie is mass selected and focused into the collinear velocity-map imaging (VMI) lens assembly. The design of the imaging lens has allowed us to obtain less than 0.9% energy resolution for high kinetic energy electrons ( > 1eV) while maintaining wavenumber resolution for low kinetic energy electrons. Although gold dimer and tetramer have been studied in the past, we present spectroscopic results under high resolution. For Au_2^-, we report high resolution spectra with an accurate determination of the electron affinity together with a complete vibrational assignment, for both the anion and neutral ground states, while for Au_4^-, we are able to resolve a low frequency mode and obtain accurately the adiabatic detachment energy.

    We have studied the charged particle forward-backward multiplicity correlation strength in 0-10% most central Au+Au collisions at \\sqrt{s_{NN}}=200 GeV by a parton and hadron cascade model, PACIAE based on PYTHIA. The real (total), statistical, and NBD (Negative Binomial Distribution) correlation strengths are calculated, respectively, with the real events, mixed events, and NBD fitting the charged particle multiplicity distribution. The corresponding STAR data are well reproduced by the real one. If the discrepancy between real and statistical correlation strengths is identified as dynamical correlation strength, the dynamical correlation strength is then just counted few percent of the total correlation strength. In addition, we also calculated the 0-5 and 5% most central Au+Au collisions and turned out that the correlation strength increases monotonously with increasing size of the centrality bin.

  8. Simulation of energy scan of pion interferometry in central Au+Au collisions at relativistic energies

    International Nuclear Information System (INIS)

    We present a systematic analysis of two-pion interferometry for the central Au+Au collisions at √sNN = 3, 5, 7, 11, 17, 27, 39, 62, 130 and 200 GeV/c with the help of a multiphase transport (AMPT) model. Emission source-size radius parameters Rlong, Rout, Rside and the chaotic parameter λ are extracted and compared with the experimental data. Transverse momentum and azimuthal angle dependencies of the HBT radii are also discussed for central Au+Au collisions at 200 GeV/c. The results show that the HBT radii in central collisions do not change much above 7 GeV/c. For central collisions at 200 GeV/c, the radii decrease with the increasing of transverse momentum pT but are not sensitive to the azimuthal angle. These results provide a theoretical reference for the energy scan program of the RHIC-STAR experiment. (authors)

    Using the Glauber model, we present the formulas for calculating the numbers of participants,spectators and binary nucleon-nucleon collisions. Based on this work, we get the pseudorapidity distributions of charged particles as the function of the impact parameter in nucleus-nucleus collisions. The theoretical results agree well with the experimental observations made by the BRAHMS Collaboration in Au+Au collisions at √SNN=200 GeV in different centrality bins over the whole pseudorapidity range.

    @@ We predict that xcJ mesons at low transverse momentum in the central rapidity region are almost dissociated by nucleons and antinucleons in hadronic matter produced in central Au+Au collisions at relativistic high-ion collider (RHIC) energies √SNN = 130 and 200 GeV. In the calculations the nucleon and antinucleon distributions in hadronic matter are results of evolution from their freeze-out distributions which well fit the experimental transverse momentum spectra of proton and antiproton.

    Argonne flow and Bose-Einstein correlations have been measured in Au-Au collisions at S=130 and 200 GeV using the PHOBOS detector at RHIC. The systematic dependencies of the flow signal on the transverse momentum, pseudorapidity, and centrality of the collision, as well as the beam energy are shown. In addition, results of a 3-dimensional analysis of two-pion correlations in the 200 GeV data are presented.

  12. Results from experiment E917 for Au + Au collisions at the AGS

    International Nuclear Information System (INIS)

    The effects of baryon stopping and its resulting energy deposition on the dynamics of Au + Au collisions at 6, 8 and 10.8 GeV/nucleon are explored with recent results from the AGS experiment E917. Current analyses of stopping, collective flow signals and HBT parameters are presented. Strangeness and anti-baryon production is examined using the yields of anti-lambdas and anti-protons

    We calculate the net baryon rapidity distribution in Au+Au collisions at the Relativistic Heavy Ion Collider (RHIC) in the framework of the Parton Cascade Model (PCM). Parton rescattering and fragmentation leads to a substantial increase in the net baryon density at mid-rapidity over the density produced by initial primary parton-parton scatterings. The PCM is able to describe the measured net baryon density at RHIC.

  14. Some thoughts on di-jet correlation in Au + Au collisions from PHENIX

    2006-01-01

    PHENIX has measured the two particle azimuth correlation in Au + Au at $\\sqrt{s}$ = 200 GeV. Jet shape and yield at the away side are found to be strongly modified at intermediate and low $p_T$, and the modifications vary dramatically with $p_T$ and centrality. At high $p_T$, away side jet peak reappears but the yield is suppressed. We discuss the possible physics pictures leading to these complicated modifications.

    We have measured the sideward flow of neutral strange ($K^0_s$) mesons in 6 AGeV Au + Au collisions. A prominent anti-flow signal is observed for an impact parameter range (b $\\lesssim 7$ fm) which spans central and mid-central events. Since the $K^0_s$ scattering cross section is relatively small in nuclear matter, this observation suggests that the in-medium kaon vector potential plays an important role in high density nuclear matter.

    The signals theoretically predicted for the occurrence of a critical behavior (conditional moments of charge distributions, Campi scatter plot, fluctuations of the size of the largest fragment, power law in the charge distribution, intermittency) have been found for peripheral events in the reaction Au+Au at 35 MeV/u. The same signals have been studied with a dynamical model which foresees phase transition, like the Classical Molecular Dynamics.

    The PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) has performed systematic measurements of phi meson production in the K+K- decay channel at midrapidity in p+p, d+Au, Cu+Cu and Au+Au collisions at sqrt(S_NN)=200 GeV. Results are presented on the phi invariant yield and the nuclear modification factor R_AA for Au+Au and Cu+Cu, and R_dA for d+Au collisions, studied as a function of transverse momentum (1Au+Au collisions, the R_AA of phi exhibits a suppression relative to expectations from binary scaled p+p results. The amount of suppression is smaller than that of the neutral pion and the eta meson in the intermediate p_T range (2--5 GeV/c); whereas at higher p_T the phi, pi^0, and eta show similar suppression. The baryon (protons and anti-protons) excess observed in central Au+Au collisions at intermediate p_T is not observed for the phi meson despite the similar mass of the proton and the phi. This suggests that the excess is lin...

    We report measurements of Upsilon meson production in p+p, d+Au, and Au+Au collisions using the STAR detector at RHIC. We compare the Upsilon 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 Upsilon(1S+2S+3S) in the rapidity range |y|<1 in d+Au collisions of R_dAu = 0.67 +/- 0.12 (stat.) +/- 0.04 (sys.) +/- 0.08 (pp sys.). 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_AA=0.36 +/- 0.09 (stat.) +/- 0.01 (sys.) +/- 0.04 (pp sys.), which is a larger suppression factor than that seen in cold nuclear matte...

    The heterofunctional and rigid ligand N,N'-diphosphanyl-imidazol-2-ylidene (PCNHCP; P = P(t-Bu)2), through its phosphorus and two N-heterocyclic carbene (NHC) donors, stabilizes trinuclear chain complexes, with either Au3 or AgAu2 cores, and dinuclear Au2 complexes. The two oppositely situated PCNHCP (L) ligands that "sandwich" the metal chain can support linear and rigid structures, as found in the known tricationic Au(I) complex [Au3(μ3-PCNHCP,κP,κCNHC,κP)2](OTf)3 (OTf = CF3SO3; [Au3L2](OTf)3; Chem. Commun. 2014, 50, 103-105) now also obtained by transmetalation from [Ag3(μ3-PCNHCP,κP,κCNHC,κP)2](OTf)3 ([Ag3L2](OTf)3), or in the mixed-metal tricationic [Au2Ag(μ3-PCNHCP,κP,κCNHC,κP)2](OTf)3 ([Au2AgL2](OTf)3). The latter was obtained stepwise by the addition of AgOTf to the digold(I) complex [Au2(μ2-PCNHCP,κP,κCNHC)2](OTf)2 ([Au2L2](OTf)2). The latter contains two dangling P donors and displays fluxional behavior in solution, and the Au···Au separation of 2.8320(6) Å in the solid state is consistent with metallophilic interactions. In the solvento complex [Au3Cl2(tht)(μ3-PCNHCP,κP,κCNHC,κP)](OTf)·MeCN ([Au3Cl2(tht)L](OTf)·MeCN), which contains only one L and one tht ligand (tht = tetrahydrothiophene), the metal chain is bent (148.94(2)°), and the longer Au···Au separation (2.9710(4) Å) is in line with relaxation of the rigidity due to a more "open" structure. Similar features were observed in [Au3Cl2(SMe2)L](OTf)·2MeCN. A detailed study of the emission properties of [Au3L2](OTf)3, [Au3Cl2(tht)L](OTf)·MeCN, [Au2L2](OTf)2, and [Au2AgL2](OTf)3 was performed by means of steady state and time-resolved photophysical techniques. The complex [Au3L2](OTf)3 displays a bright (photoluminescence quantum yield = 80%) and narrow emission band centered at 446 nm with a relatively small Stokes' shift and long-lived excited-state lifetime on the microsecond timescale, both in solution and in the solid state. In line with the very narrow emission

    We present transverse momentum distributions of charged hadrons produced in Au+Au collisions at sNN=200 GeV. The spectra were measured for transverse momenta pT from 0.25 to 4.5 GeV/c in a pseudorapidity range of 0.2<η<1.4. The evolution of the spectra is studied as a function of collision centrality, from 65 to 344 participating nucleons. The results are compared to data from proton-antiproton collisions and Au+Au collisions at lower RHIC energies. We find a significant change of the spectral shape between proton-antiproton and semi-peripheral Au+Au collisions. Comparing semi-peripheral to central Au+Au collisions, we find that the yields at high pT exhibit approximate scaling with the number of participating nucleons, rather than scaling with the number of binary collisions.

    We report on the observed differences in production rates of strange and multi-strange baryons in Au+Au collisions at sqrts = 200 GeV compared to p+p interactions at the same energy. The yields in Au+Au collisions, when scaled by the number of participants, are larger than those measured in the p+p data. The magnitudes of the differences grow with the strangeness of the baryon and with increasing centrality. The enhancements of the Au+Au yields are close to those measured in sqrts = 17.3 GeV collisions. Further, when the binary scaled p+p pT spectra are compared to those of Au+Au the heavy-ion yields exceed binary scaling in the pT range 1 < pT< 4 GeV/c.

    2015-12-01

    Full Text Available 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.

    The STAR collaboration presents new two-dimensional di-hadron correlations with 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 enhancement for leading non-pions (protons and kaons) are discussed within the context of quark recombination. The correlated yield at large angles, specifically in the \\emph{ridge region}, is 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.

    Combined scanning tunneling microscopy and ion-scattering studies have revealed a new "dealloying" phase transition during the growth of Au on Ni(110). The Au atoms, which initially alloy into the Ni(110) surface, phase separate into a vacancy-stabilized Au dimer-trimer chain structure at Au...... coverages larger than 0.4 monolayer. Using the effective-medium theory, we show that the resulting structure as well as the physical mechanism responsible for the phase transition are closely related to the surface stress induced by the substituted Au....

    We have measured transverse momentum distributions of charged hadrons produced in d+Au collisions at √SNN = 200 GeV, in the range 0.25 < pT < 6.0 GeV/c. With increasing collision centrality, the yield at high transverse momenta increases more rapidly than the overall particle density, leading to a strong modification of the spectral shape. This change in spectral shape is qualitatively different from observations in Au+Au collisions at the same energy. The results provide important information for discriminating between different models for the suppression of high-pT hadrons observed in Au+Au collisions.

    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. Continuous curriculum review in a bachelor of nursing program: preventing curriculum drift and improving quality.

    2010-10-01

    Higher education institutions have rigorous internal accreditation processes for new courses and typically require thorough course reviews every 5 years. Courses such as nursing must also be accredited by professional registration boards. However, in the years between initial accreditation and formal reaccreditation cycles, the risk of a widening gap between the accredited curriculum and the taught curriculum is real when there is no process to monitor the changes that individual unit assessors make to their subjects as they teach them. This curriculum drift may interfere with the intended development of graduate attributes and the taxonomic structure of assessment tasks across the course. This article describes the implementation of a formative continuous curriculum review process that prevents curriculum drift and enhances the quality of a bachelor of nursing curriculum.

    Polyethylene (PE) surface was treated with Ar plasma. Activated surface was grafted from methanol solution of 1,2-ethanedithiol. Then the sample was immersed into freshly prepared colloid solution of Au-nanoparticles. Finally Au layer was sputtered on the samples. Properties of the modified PE were studied using various methods: AFM, EPR, RBS and nanoindentation. It was shown that the plasma treatment results in degradation of polymer chain (AFM) and creation of free radicals by EPR. After grafting with dithiol, the concentration of free radicals declines. The presence of Au and S in the surface layer after the coating with Au-nanoparticles was proved by RBS. Plasma treatment changes PE surface morphology and increases surface roughness, too. Another significant change in surface morphology and roughness was observed after deposition of Au-nanoparticles. Nanoindentation measurements show that the grafting with Au-nanoparticles increases adhesion of subsequently sputtered Au layer.

    The design of functional two-dimensional molecular networks has become an area of intense research. The constraint to 2 in contrast to the availability of 3 dimensions has a large impact on many chemical reactions. Chemical reactions between surface adsorbed molecules may lead to products very different from those obtained in solutions or the gas phase. The imide formation between a diaminoterphenyl (DATP) and a PTCDA molecule is one very interesting example in this respect. In scanning tunneling microscopy (STM) experiments, it has been observed that the Au surface changes both the reaction path and the reaction product compared to 3D. In order to understand these experimental observations, we have studied the chemical reactions both in solution and on the Au(111) surface by density-functional theory calculations in the generalized-gradient approximation.

    Vanadium dioxide (VO2) is known to have a semiconductor-to-metal phase transition at ˜68 °C. Therefore, it can be used as a tunable component of an active metamaterial. The lamellar metamaterial studied in this work is composed of subwavelength VO2 and Au layers and is designed to undergo a temperature controlled transition from the optical hyperbolic phase to the metallic phase. VO2 films and VO2/Au lamellar metamaterial stacks have been fabricated and studied in electrical conductivity and optical (transmission and reflection) experiments. The observed temperature-dependent changes in the reflection and transmission spectra of the metamaterials and VO2 thin films are in a good qualitative agreement with theoretical predictions. The demonstrated optical hyperbolic-to-metallic phase transition is a unique physical phenomenon with the potential to enable advanced control of light-matter interactions.

    2015-12-01

    Ion irradiation of nanoparticles leads to enhanced sputter yields if the nanoparticle size is of the order of the ion penetration depth. While this feature is reasonably well understood for collision-cascade sputtering, we explore it in the regime of collision-spike sputtering using molecular-dynamics simulation. For the particular case of 200-keV Xe bombardment of Au particles, we show that collision spikes lead to abundant sputtering with an average yield of 397 ± 121 atoms compared to only 116 ± 48 atoms for a bulk Au target. Only around 31 % of the impact energy remains in the nanoparticles after impact; the remainder is transported away by the transmitted projectile and the ejecta. The sputter yield of supported nanoparticles is estimated to be around 80 % of that of free nanoparticles due to the suppression of forward sputtering.

    2012-01-01

    In the early 18th century, at the founding of Edinburgh University Medical School, the study of botany was regarded as an essential component of medical training. Botanical teaching began as basic instruction in the recognition of medical plants, considered a vital aspect of a physician's Materia Medica studies. Over the next hundred years growing importance was given to the study of botany as a science, its popularity peaking under John Hutton Balfour's tenure as Professor (1845-1879). The relevance of botanical study later declined in the undergraduate medical curriculum until its cessation in 1961 .This paper considers the history of botanical studies in Edinburgh, including the reasons for its introduction and its changing importance over time.

  10. Jet structure of baryon excess in Au+Au collisions at √(sNN)=200 GeV

    International Nuclear Information System (INIS)

    Two particle correlations between identified meson and baryon trigger particles with 2.5TT charged hadrons have been measured at midrapidity by the PHENIX experiment at RHIC in p+p,d+Au, and Au+Au collisions at √(sNN)=200 GeV. In noncentral Au+Au collisions, the probability of finding a hadron near in azimuthal angle to the trigger particles is almost identical for mesons and baryons and significantly higher than in p+p collisions. The associated yields for trigger baryons decrease in the most central collisions, consistent with some baryon production by thermal recombination in addition to hard scattering

  11. Mammalian sensitivity to elemental gold (Au?)

    Eisler, R.

    2004-01-01

    There is increasing documentation of allergic contact dermatitis and other effects from gold jewelry, gold dental restorations, and gold implants. These effects were especially pronounced among females wearing body-piercing gold objects. One estimate of the prevalence of gold allergy worldwide is 13%, as judged by patch tests with monovalent organogold salts. Eczema of the head and neck was the most common response of individuals hypersensitive to gold, and sensitivity can last for at least several years. Ingestion of beverages containing flake gold can result in allergic-type reactions similar to those seen in gold-allergic individuals exposed to gold through dermal contact and other routes. Studies with small laboratory mammals and injected doses of colloidal gold showed increased body temperatures, accumulations in reticular cells, and dose enhancement in tumor therapy; gold implants were associated with tissue injuries. It is proposed that Au? toxicity to mammals is associated, in part, with formation of the more reactive Au+ and Au3+ species.

  12. Electric Field Induced Surface Modification of Au

    We discuss the role of localized high electric fields in the modification of Au surfaces with a W probe using the Interfacial Force Microscope. Upon bringing a probe close to a Au surface, we measure both the interfacial force and the field emission current as a function of separation with a constant potential of 100 V between tip and sample. The current initially increases exponentially as the separation decreases. However, at a distance of less than {approximately} 500{angstrom} the current rises sharply as the surface begins to distort and rapidly close the gap. Retraction of the tip before contact is made reveals the formation of a mound on the surface. We propose a simple model, in which the localized high electric field under the tip assists the production of mobile Au adatoms by detachment from surface steps, and a radial field gradient causes a net flux of atoms toward the tip by surface diffusion. These processes give rise to an unstable surface deformation which, if left unchecked, results in a destructive mechanical contact. We discuss our findings with respect to earlier work using voltage pulses in the STM as a means of nanofabrication.

  13. Suppression of high transverse momentum π0 spectra in Au + Au collisions at RHIC

    Science.gov (United States)

    Kahana, D. E.; Kahana, S. H.

    2008-02-01

    Au + Au, s1/2 = 200 GeV measurements at RHIC, obtained with the PHENIX, STAR, PHOBOS and BRAHMS detectors, have all indicated a suppression of high p⊥ particle production, relative to an appropriately normalized NN level. For central collisions and vanishing pseudo-rapidity these experiments exhibit suppression in charged meson production, especially at medium-to-large transverse momenta. In the PHENIX experiment similar behaviour has been reported for π0 spectra. In a recent work [1] on the simpler D + Au interaction, to be considered perhaps as a tune-up for Au + Au, we reported on a pre-hadronic cascade mechanism which can explain the mixed observation of moderately reduced p⊥ suppression at higher pseudo-rapidity as well as the Cronin enhancement at mid-rapidity. Here, we present the extension of this work to the more massive ion-ion collisions. Our major thesis is that much of the suppression is generated in a late stage cascade of colourless pre-hadrons produced after an initial short-lived coloured phase. We present a pQCD argument to justify this approach and to estimate the time duration τp of this initial phase. Of essential importance is the brevity in time of the coloured phase existence relative to that of the strongly interacting pre-hadron phase, the latter essentially an interactive cascade. These distinctions in phase are of course not strict, but adequate for treating the suppression of moderate and high p⊥ mesons.

    Full Text Available Medical education has witnessed tremendous development in the last three decades. The traditional lecture based didactic teaching is gradually replaced with small group teaching; problem- based learning; learning with standardized patients and community-oriented medical education.Traditional methods of teaching and learning are no longer considered the most appropriate approach and new methods of teaching and learning are based on strong foundation of educational theories. Students are the focus point while designing medical curriculum and teaching and learning should be student centered. The traditional approach of sorting curriculum; based upon subject areas; is no longer considered appropriate and curriculum requires integration of various disciplines. Community needs are of utmost importance while designing curriculum. Students should be offered various electives so that the teaching and learning is individualized and fulfilling the community needs as well.

    As innovation is seen as a key factor in economic competitiveness, graduates who can contribute to and participate in innovation are in great need.. Higher education is confronted with the demands that the curriculum practice and learning environments should facilitate innovation and competences...... for innovation. Problem and project based learning has been seen as a strategy for renewing the teaching practice and the learning environment by integrating the competence demands of the curriculum and of work life during the process of education. However, the integrations of innovation into curriculum...... are minor in the problem and project based learning (PBL) literature. Based on theoretical reflections and practical cases in Aalborg University (Denmark), this article presents the basis of PBL knowledge and curriculum conceptualization, and explores a case experience which bridges innovation and PBL...

    Curriculum and psychoeducational groups have become increasingly popular because of their strong evidence base and presumed ease of implementation. The curriculum provides a valuable guide to social workers leading groups as they decide on topics for discussion. Typically, the literature emphasizes the content--the material being presented--over the process: the ways in which members interact with one another and with the leader. The authors of this article contend that when the social worker adheres too rigidly to the content, members' ability to make meaning of and internalize the information being presented is compromised. They advocate for an approach to group facilitation that emphasizes flexible presentation of curriculum topics. The benefits of group participation are maximized when collaborative learning, which involves members' interactions with one another and the leader, is encouraged. The article includes a summary of the theoretical foundation and evidence base of psychoeducational and curriculum groups and presents strategies to promote collaborative learning using case examples.

    Full Text Available The aim of this study is to analyse and discuss, with regard tothe Curriculum Relation Model proposed by Berit Johnsen, how to plan a meaningful and individually adapted curriculum related to class curriculum as a means to realise the international principle of inclusive education.Methods. The methods involve scientific and pedagogical analyses of one of the recent and sophisticated theories relating to the best model of an adapted curriculum and literature review for the international principle of inclusive education.Results. Detailed investigation of Curriculum Relation Model reveals that this model involves all relevant aspects which should be taken into consideration when curriculum needs adaptation within inclusive education setting all over the world. An extension of the model with all the relevant aspects (the pupil/s, educational intentions, educational content, methods and organisation, assessment, communication, care and context/frame factors makes it an ideal tool for a teacher/special needs educator to plan meaningful and individually adapted curriculum with a full relation to class curriculum. As for the international principle of inclusive education, literature review suggest that there are several international declarations and other relevant documents proposed by the United Nations regarding the rights of children with special needs to quality education without being exposed to any kinds of discrimination.Scientific novelty. Scientific novelty of the study involves a fresh innovation in the sphere of curriculum development which still keeps its importance urgency in the countries initiating reforms in education.Practical significance. Currently, inclusive education is an intensively discussed issue almost in all the countries. Although inclusive education has a history of couple of decades, some countries are at the beginning of inclusive education initiation. This is a point they come across quite a lot

Students' levels of knowledge vary widely between different therapies. Most medic...

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

    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.

  9. Synthesis and characterization of Au@Pt nanoparticles

    Aucore-Ptshell (Au@Pt) nanoparticles were synthesized at room temperature by reducing K2PtCl6 with hydrogen in the solution containing Au colloids and polyvinylpyrrolidone (PVP). The particles obtained were characterized with UV-Vis, TEM and XPS techniques. UV-Vis spectra show that the surface plasmon absorption feature of Au colloids is significantly reduced with increasing the amount of reduced Pt. TEM images that the metals are found always appear as spherical nanoparticles and their sizes grow apparently due to the reduction of PtCl62- ions, indicating that Pt is deposited from solution onto Au particle surface and forms a Pt-layer with uniform thickness. In the XPS spectra, the signals of Au metal decrease due to the reductive deposition of Pt on the surface of the Au colloids. UV-Vis and XPS data are consistent in showing that when the amount of Pt in the AuPt colloids is increased to reach an overall atomic ratio of Pt/Au=2, the Pt deposits form a shell covering completely the surface of Au particles, demonstrating the core-shell structure of the synthesized AuPt particles.

    Based on the observation of the long-lived isotopes 261Rg and 265Rg (Z = 111, t(1/2) >= 10^(8) y) in natural Au, an experiment was performed to enrich Rg in 99.999% Au. 16 mg of Au were heated in vacuum for two weeks at a temperature of 1127 deg. C (63 deg. C above the melting point of Au). The content of 197Au and 261Rg in the residue was studied with high resolution inductively coupled plasma-sector field mass spectrometry (ICP-SFMS). The residue of Au was 3x10^(-6) of its original quantity. The recovery of Rg was a few percent. The abundance of Rg compared to Au in the enriched solution was about 2x10^(-6), which is a three to four orders of magnitude enrichment. It is concluded that the evaporation rate of Rg from an Au matrix in vacuum at 63 deg. C above the Au melting point is lower than that of Au. This experiment reinforces our first observation of Rg in a terrestrial material. As before it is concluded that a long-lived isomeric state exists in 261Rg and that it probably belongs to a new class of iso...

  11. Digestive oncologist in the gastroenterology training curriculum

    Until the late 1980s, gastroenterology (GE) was consid-ered a subspecialty of Internal Medicine. Today, GE also incorporates Hepatology. However, Digestive Oncology training is poorly defined in the Hepatogastroenterology (HGE)-curriculum. Therefore, a Digestive Oncology cur-riculum should be developed and this document might be a starting point for such a curriculum. HGE-specialists are increasingly resisting the paradigm in which they play only a diagnostic and technical role in the manage-ment of digestive tumors. We suggest minimum end-points in the standard HGE-curriculum for oncology, and recommend a focus year in the Netherlands for Diges-tive Oncology in the HGE-curriculum. To produce well-trained digestive oncologists, an advanced Digestive Oncology training program with specific qualifications in Digestive Oncology (2 years) has been developed. The schedule in Belgium includes a period of at least 6 mo to be spent in a medical oncology department. The goal of these programs remains the production of well-trained digestive oncologists. HGE specialists are part of the multidisciplinary oncological teams, and some have been administering chemotherapy in their countries for years. In this article, we provide a road map for the organiza-tion of a proper training in Digestive Oncology. We hope that the World Gastroenterology Organisation and other (inter)national societies will support the necessary certi-fications for this specific training in the HGE-curriculum.

    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.

  14. PARTON STRUCTURE THROUGH TWO PARTICLE CORRELATIONS IN AU-AU AT RHIC.

    Energy Technology Data Exchange (ETDEWEB)

    LONGACRE,R.S.

    1999-10-23

    A method for determining the presence of partonic scattering through two-particle correlations is developed and applied to models which have jets and mini-jets in them. We only consider the correlation of mid-rapidity particles because they will be easily measured in large numbers at RHIC. The level of two-particle correlations will be a direct measure of how dense a system is made in Au-Au collisions at RHIC. The STAR TPC will be ideal for making these measurements in the first year of running.

    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.

  16. Spectator matter fragmentation in Au+Au reactions: Phase space analysis

    2011-01-01

    Clusterization in phase space has been analyzed for peripheral Au+Au reactions at 1000 AMeV using simulated annealing clusterization algorithm (SACA). We investigate how these fragments are correlated in phase space and compare our model calculations with minimum spanning tree (MST) method. Our theoretical study highlights the importance of binding energy criterion in recognizing the fragment structure. MST method however, fails to break-up the spectator matter effectively and thus under-estimates the multiplicity of intermediate mass fragments (IMFs).

    We present the first measurement of the pseudorapidity density of primary charged particles in Au+Au collisions at (sNN) = 200 GeV. For the 6% most central collisions, we obtain dNch/dη\\|\\|η\\|<1 = 650+/-35(syst). Compared to collisions at (sNN) = 130 GeV, the highest energy studied previously, an increase by a factor of 1.14+/-0.05 at 90% confidence level, is found. The energy dependence of the pseudorapidity density is discussed in comparison with data from proton-induced collisions and theoretical predictions.

    Organic synthesis using gold has gained tremendous attention in last few years, especially heterogeneous gold catalysis based on gold nanoparticles has made its place in almost all organic reactions, because of the robust and green nature of gold catalysts. In this context, gold nanopore (AuNPore) with a 3D metal framework is giving a new dimension to heterogeneous gold catalysts. Interestingly, AuNPore chemistry is proving better than gold nanoparticles based chemistry. In this review, along with recent advances, major discoveries in heterogeneous gold catalysis are discussed.

  19. Observation of anisotropic event shapes and transverse flow in ultrarelativistic Au+Au collisions

    International Nuclear Information System (INIS)

    Event shapes for Au + Au collisions at 11.4 GeV/c per nucleon were studied over nearly the full solid angle with the E877 apparatus. The analysis was performed by Fourier expansion of azimuthal distributions of the transverse energy (ET) measured in different pseudorapidity intervals. For semicentral collisions a pronounced event anisotropy is identified with a clear forward-backward anticorrelation. In the forward pseudorapidity interval up to 9% of the ET is in a directed component. The signal decreases for peripheral and very central collisions

    Data from Au + Au interactions at sqrt[s(NN)]=130 GeV, obtained with the PHENIX detector at the Relativistic Heavy-Ion Collider, are used to investigate local net charge fluctuations among particles produced near midrapidity. According to recent suggestions, such fluctuations may carry information from the quark-gluon plasma. This analysis shows that the fluctuations are dominated by a stochastic distribution of particles, but are also sensitive to other effects, like global charge conservation and resonance decays.

  1. Light Fragment Production and Power Law Behavior in Au + Au Collisions

    International Nuclear Information System (INIS)

    Using charged-particle-exclusive measurements of Au+Au collisions in the LBL Bevalac's EOS time projection chamber, we investigate momentum-space densities of fragments up to 4He as a function of fragment transverse momentum, azimuth relative to the reaction plane, rapidity, multiplicity, and beam energy. Most features of these densities above a transverse momentum threshold are consistent with momentum-space coalescence, and, in particular, the increase in sideward flow with fragment mass is generally well described by a momentum-space power law

    Some aspects of the direct photon production phenomenon are discussed, mainly in the Pb+Pb and Au+Au collisions on the basis of a model for production of the same particle species in PP collisions. The results have, thereafter, been converted to those for a few AB/AA interactions through an appropriate mechanism. Comparison of the theoretical results obtained on the basis of model-based calculations with measured data on the relevant observables leads to a fair agreement between them. This reflects modestly the fair achievements attained by the models that are made use of in the present work. (author)

    Using the large acceptance Time Projection Chamber of experiment E895 at Brookhaven, measurements of collective sideward flow in Au + Au collisions at beam energies of 2, 4, 6 and 8A GeV are presented in the form of in-plane transverse momentum and the first Fourier coefficient of azimuthal anisotropy v_1. These measurements indicate a smooth variation of sideward flow as a function of beam energy. The data are compared with four nuclear transport models which have an orientation towards this energy range. All four exhibit some qualitative trends similar to those found in the data, although none shows a consistent pattern of agreement within experimental uncertainties.

    Momentum spectra of charged pions over nearly full rapidity coverage from target to beam rapidity have been measured in the 0-5% most central Au+Au collisions in the beam energy range from 2 to 8 AGeV by the E895 Experiment. Using a thermal parameterization to fit the transverse mass spectra, rapidity density distributions are extracted. The observed spectra are compared with predictions from the RQMD v2.3 cascade model and also to a thermal model including longitudinal flow. The total 4$pi$ yields of the charged pions are used to infer an initial state entropy produced in the collisions.

    The Chiral Magnetic Effect (CME) is predicted for Au-Au collisions at RHIC. However, many backgrounds can give signals that make the measurement hard to interpret. The STAR experiment has made measurements at different collisions energy ranging from √(sNN)=7.7 GeV to 62.4 GeV. In the analysis that is presented we show that the CME turns on with energy and is not present in central collisions where the induced magnetic is small.

  8. Azimuthal Anisotropy of Identified Hadrons in 200 GeV Au+Au Collisions

    2006-01-01

    The azimuthal anisotropy parameter v2 has been measured with high statistics for identified hadrons in sqrt(s_NN) = 200 GeV Au+Au collisions with the STAR experiment. At high transverse momentum (pT) a strong v2 for pi+ + pi- and p + pbar is observed. In the intermediate pT region, number-of-constituent-quark scaling was tested to high precision. A detailed comparison of v2 for the multi-strange hadrons phi, Xi + anti-Xi, and Omega + anti-Omega with other particle species substantiates the development of collectivity among partons in the early phase of the collisions at RHIC.

  9. The critical thinking curriculum model

    Robertson, William Haviland

    The Critical Thinking Curriculum Model (CTCM) utilizes a multidisciplinary approach that integrates effective learning and teaching practices with computer technology. The model is designed to be flexible within a curriculum, an example for teachers to follow, where they can plug in their own critical issue. This process engages students in collaborative research that can be shared in the classroom, across the country or around the globe. The CTCM features open-ended and collaborative activities that deal with current, real world issues which leaders are attempting to solve. As implemented in the Critical Issues Forum (CIF), an educational program administered by Los Alamos National Laboratory (LANL), the CTCM encompasses the political, social/cultural, economic, and scientific realms in the context of a current global issue. In this way, students realize the importance of their schooling by applying their efforts to an endeavor that ultimately will affect their future. This study measures student attitudes toward science and technology and the changes that result from immersion in the CTCM. It also assesses the differences in student learning in science content and problem solving for students involved in the CTCM. A sample of 24 students participated in classrooms at two separate high schools in New Mexico. The evaluation results were analyzed using SPSS in a MANOVA format in order to determine the significance of the between and within-subjects effects. A comparison ANOVA was done for each two-way MANOVA to see if the comparison groups were equal. Significant findings were validated using the Scheffe test in a Post Hoc analysis. Demographic information for the sample population was recorded and tracked, including self-assessments of computer use and availability. Overall, the results indicated that the CTCM did help to increase science content understanding and problem-solving skills for students, thereby positively effecting critical thinking. No matter if the

    2013-03-01

    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.
