Written Language Shift among Norwegian Youth

Directory of Open Access Journals (Sweden)

Kamil ÖZERK

2013-07-01

Full Text Available In Norway there are two written Norwegian languages, Bokmål and Nynorsk. Of these two written languages Bokmål is being used by the majority of the people, and Bokmål has the highest prestige in the society. This article is about the shift of written language from Nynorsk to Bokmål among young people in a traditional Nynorsk district in the country. Drawing on empirical data we conclude that many adolescents are experiencing written language shift. We discuss various reasons for this phenomenon in the linguistic landscape of Norway. In our discussions we emphasize the importance of the school with regard to language maintenance and language revitalization. We call for a new language policy in the educational system that can prevent language shift. Having several dialects and two officially written forms of Norwegian in the country, creates a special linguistic landscape in Norway. Despite the fact that the Norwegian language situation is in several ways unique, it’s done very little research on how the existing policy works in practice. Our research reveals that the existing language policy and practice in the school system is not powerful enough to prevent language shift and language decay among the youngsters. The school system functions like a fabric for language shift.

Evanescent fields of laser written waveguides

Science.gov (United States)

Jukić, Dario; Pohl, Thomas; Götte, Jörg B.

2015-03-01

We investigate the evanescent field at the surface of laser written waveguides. The waveguides are written by a direct femtosecond laser writing process into fused silica, which is then sanded down to expose the guiding layer. These waveguides support eigenmodes which have an evanescent field reaching into the vacuum above the waveguide. We study the governing wave equations and present solution for the fundamental eigenmodes of the modified waveguides.

Selvaraj, Sathees Kannan [Department of Chemical Engineering, University of Illinois at Chicago, Chicago, Illinois 60607 (United States); Takoudis, Christos G., E-mail: takoudis@uic.edu [Department of Chemical Engineering, University of Illinois at Chicago, Chicago, Illinois 60607 and Department of Bioengineering, University of Illinois at Chicago, Chicago, Illinois 60607 (United States)

2015-01-01

The authors report the development and implementation of a scalable control program to control flow type atomic layer deposition (ALD) reactor with multiple precursor delivery lines. The program logic is written and tested in LABVIEW environment to control ALD reactor with four precursor delivery lines to deposit up to four layers of different materials in cyclic manner. The programming logic is conceived such that to facilitate scale up for depositing more layers with multiple precursors and scale down for using single layer with any one precursor in the ALD reactor. The program takes precursor and oxidizer exposure and purging times as input and controls the sequential opening and closing of the valves to facilitate the complex ALD process in cyclic manner. The program could be used to deposit materials from any single line or in tandem with other lines in any combination and in any sequence.

The challenge of giving written thesis feedback to nursing students.

Science.gov (United States)

Tuvesson, Hanna; Borglin, Gunilla

2014-11-01

Providing effective written feedback on nursing student's assignments can be a challenging task for any assessor. Additionally, as the student groups tend to become larger, written feedback is likely to gain an overall more prominent position than verbal feedback. Lack of formal training or regular discussion in the teaching faculty about the skill set needed to provide written feedback could negatively affect the students' learning abilities. In this brief paper, we discuss written feedback practices, whilst using the Bachelor of Science in Nursing thesis as an example. Our aim is to highlight the importance of an informed understanding of the impact written feedback can have on students. Creating awareness about this can facilitate the development of more strategic and successful written feedback strategies. We end by offering examples of some relatively simple strategies for improving this practice. Copyright © 2014 Elsevier Ltd. All rights reserved.

Improving Written Language Performance of Adolescents with Asperger Syndrome

Science.gov (United States)

Delano, Monica E

2007-01-01

The effects of a multicomponent intervention involving self-regulated strategy development delivered via video self-modeling on the written language performance of 3 students with Asperger syndrome were examined. During intervention sessions, each student watched a video of himself performing strategies for increasing the number of words written and the number of functional essay elements. He then wrote a persuasive essay. The number of words written and number of functional essay elements included in each essay were measured. Each student demonstrated gains in the number of words written and number of functional essay elements. Maintenance of treatment effects at follow-up varied across targets and participants. Implications for future research are suggested. PMID:17624076

Eva Kodrič-Dačić

2013-09-01

Full Text Available ABSTRACTPurpose: Libraries collect written cultural heritage which is not only the most valuable part of their collections but also a part of library materials which is, due to digitalization projects in the last decade, becoming more and more interesting to librarians and library users. The main goal of the study is a theoretical research of library materials acknowledged as Slovenian heritage. By defining the basic terms it highlights the attributes which are immanent to library materials, derived from the context of their origin or later destiny. Slovenian library legislation concerning protection of written cultural heritage is also critically analysed.Methodology/approach: Comparative analyses of European and Slovenian legislation concerning librarianship and written cultural heritage. Research limitation: Research was mainly limited to professional literature and resources dealing with written cultural heritage. Originality/practical implications: Results of the research serve as formal criteria for definition of library materials as written heritage and suggest how to improve legislation in the field of protection of written heritage in libraries.

Vacuum deposition onto webs, films and foils

CERN Document Server

Bishop, Charles A

2011-01-01

Roll-to-roll vacuum deposition is the technology that applies an even coating to a flexible material that can be held on a roll and provides a much faster and cheaper method of bulk coating than deposition onto single pieces or non-flexible surfaces, such as glass. This technology has been used in industrial-scale applications for some time, including a wide range of metalized packaging (e.g. snack packets). Its potential as a high-speed, scalable process has seen an increasing range of new products emerging that employ this cost-effective technology: solar energy products are moving from rigid panels onto flexible substrates, which are cheaper and more versatile; in a similar way, electronic circuit 'boards' can be produced on a flexible polymer, creating a new range of 'flexible electronics' products; and, flexible displays are another area of new technology in vacuum coating, with flexible display panels and light sources emerging. Charles Bishop has written this book to meet the need he identified, as a t...

Managing Written Directives: A Software Solution to Streamline Workflow.

Science.gov (United States)

Wagner, Robert H; Savir-Baruch, Bital; Gabriel, Medhat S; Halama, James R; Bova, Davide

2017-06-01

A written directive is required by the U.S. Nuclear Regulatory Commission for any use of 131 I above 1.11 MBq (30 μCi) and for patients receiving radiopharmaceutical therapy. This requirement has also been adopted and must be enforced by the agreement states. As the introduction of new radiopharmaceuticals increases therapeutic options in nuclear medicine, time spent on regulatory paperwork also increases. The pressure of managing these time-consuming regulatory requirements may heighten the potential for inaccurate or incomplete directive data and subsequent regulatory violations. To improve on the paper-trail method of directive management, we created a software tool using a Health Insurance Portability and Accountability Act (HIPAA)-compliant database. This software allows for secure data-sharing among physicians, technologists, and managers while saving time, reducing errors, and eliminating the possibility of loss and duplication. Methods: The software tool was developed using Visual Basic, which is part of the Visual Studio development environment for the Windows platform. Patient data are deposited in an Access database on a local HIPAA-compliant secure server or hard disk. Once a working version had been developed, it was installed at our institution and used to manage directives. Updates and modifications of the software were released regularly until no more significant problems were found with its operation. Results: The software has been used at our institution for over 2 y and has reliably kept track of all directives. All physicians and technologists use the software daily and find it superior to paper directives. They can retrieve active directives at any stage of completion, as well as completed directives. Conclusion: We have developed a software solution for the management of written directives that streamlines and structures the departmental workflow. This solution saves time, centralizes the information for all staff to share, and decreases

Improving the use of historical written sources in paleopathology.

Science.gov (United States)

Mitchell, Piers D

2017-12-01

The texts written by the people of past societies can provide key information that enhances our understanding of disease in the past. Written sources and art can describe cultural contexts that not only help us interpret lesions in excavated human remains, but also provide evidence for past disease events themselves. However, in recent decades many biohistorical articles have been published that claim to diagnose diseases present in past celebrities or well known individuals, often using less than scholarly methodology. This article aims to help researchers use historical written sources and artwork responsibly, thus improving our understanding of health and disease in the past. It explores a broad range of historical sources, from medical texts and histories to legal documents and tax records, and it highlights how the key to interpreting any past text is to understand who wrote it, when it was written, and why it was written. Case studies of plague epidemics, crucifixion, and the spinal deformity of King Richard III are then used to highlight how we might better integrate archaeological and historical evidence. When done well, integrating evidence from both archaeological and historical sources increases the probability of a complete and well-balanced understanding of disease in past societies.

Teaching Written Communication Strategies: A Training to Improve Writing

Directory of Open Access Journals (Sweden)

Hanane Benali Taouis

2018-03-01

Full Text Available This research can be described as an experimental quantitative one including: a strategy training; two homogenous experimental groups with different levels of proficiency; and two homogenous control groups. The subjects are 60 Spanish high school students, who have been selected after taking the Oxford Quick Placement-Test. The study aims at investigating the possible relationship between the effect of the strategy training and the subjects' level of proficiency. It is also designed to analyze the effect of the training on the use of communication strategies in the written medium. It is meant to study the effect of the strategy training on the subjects' writing skill in English. The results show that the students' level of proficiency exerts a strong effect on the subjects' use of written communication strategies (CSs and on their strategy preference in written production. They also demonstrate how strategy training improves the subjects' written communication ability.

Deposition of inhaled particles in the respiratory tract as a function of age at exposure

International Nuclear Information System (INIS)

Thomas, R.G.; Healy, J.W.

1985-01-01

A respiratory tract deposition model was developed that would accommodate age 1 month to adulthood as an initial step in calculating radiation dose following inhalation during environmental exposures. The approach to changing respiratory tract and physiological parameters to be applicable to children was to derive an analytical function describing the ratio of the child value to the value for a reference adult with the desired characteristics. A computer program was written to carry out the tracing of airflow through the respiratory tract and deposition in each of the sections for monodispersed particles of known density and diameter. 7 references

2014-11-01

Mounting evidence supports the use of face-to-face pain neuroscience education for the treatment of chronic pain patients. This study aimed at examining whether written education about pain neuroscience improves illness perceptions, catastrophizing, and health status in patients with fibromyalgia. A double-blind, multicenter randomized controlled clinical trial with 6-month follow-up was conducted. Patients with FM (n = 114) that consented to participate were randomly allocated to receive either written pain neuroscience education or written relaxation training. Written pain neuroscience education comprised of a booklet with pain neuroscience education plus a telephone call to clarify any difficulties; the relaxation group received a booklet with relaxation education and a telephone call. The revised illness perception questionnaire, Pain Catastrophizing Scale, and fibromyalgia impact questionnaire were used as outcome measures. Both patients and assessors were blinded. Repeated-measures analyses with last observation carried forward principle were performed. Cohen's d effect sizes (ES) were calculated for all within-group changes and between-group differences. The results reveal that written pain neuroscience education does not change the impact of FM on daily life, catastrophizing, or perceived symptoms of patients with FM. Compared with written relaxation training, written pain neuroscience education improved beliefs in a chronic timeline of FM (P = 0.03; ES = 0.50), but it does not impact upon other domains of illness perceptions. Compared with written relaxation training, written pain neuroscience education slightly improved illness perceptions of patients with FM, but it did not impart clinically meaningful effects on pain, catastrophizing, or the impact of FM on daily life. Face-to-face sessions of pain neuroscience education are required to change inappropriate cognitions and perceived health in patients with FM. © 2013 World Institute of Pain.

The influence of the pregroove on the shape of thermomagnetically written domains

International Nuclear Information System (INIS)

Ichihara, K.

1990-01-01

In order to clarify the influence of pregrooved substrates on the shape of thermomagnetically written domains, the difference between the shape of the domains written on a pregrooved area and that written on a mirror area have been examined. Trilayered magneto-optical media, which had rare-earth- (RE-) rich TbFeCo films, transition-metal-rich TbFeCo films, and RE-rich GdTbFeCo films as a recording layer, were sputtered on disk substrates. The substrates had both a pregrooved area and a mirror area in a recording track. The domains were written in each medium by varying the recording power and the external field, and were observed by an Ar + -laser scanning polarized microscope. In the case of TbFeCo media which were written with lower recording power condition, the shape of the domains on a pregrooved area were almost the same as those written on a mirror area. On the other hand, the widths of the domains written on a mirror area became larger than those of domains written on a pregrooved area when the recording power was increased. In the case of a GdTbFeCo medium, the widths of the domains written on a mirror area were much larger than those of domains written on a pregrooved area independent of the recording conditions. The lengths of the domains written on both areas were almost the same for all cases. It is believed that the reason for the experimental results is that thermal diffusion in the film plane is suppressed at the step of a pregroove. The different result between TbFeCo and GdTbFeCo films is believed to come from the differences in the contracting forces on the domain walls during the writing process

On written expression of primary school pupils

Directory of Open Access Journals (Sweden)

Stevanović Jelena

2009-01-01

Full Text Available Normative rules of standard Serbian language are acquired during primary and secondary education through curriculum demands of Serbian language instruction, which takes place in three fields: grammar, orthography and culture of expression. Topic of interest in this paper is the quality of written expression of 6th and 7th grade pupils, in the context of all three fields specified to be mastered by the curriculum of Serbian language. Research comprised 148 primary school pupils from Belgrade. Linguistic analysis of spontaneously created written text was performed, in the conditions where it was not explicitly demanded form the pupil to write correctly. The results indicate that the majority of pupils make spelling and grammatical errors, meeting the condition for the basic level of mastering the knowledge in Serbian language according to the standards specified for the end of compulsory education. In addition to this, a considerable majority of pupils has a satisfactory level of culture of written expression. Pupils more often make spelling than grammatical errors. Seventh grade pupils are better than sixth grade pupils with respect to adhering to grammar rules and according to culture of written expression, while the mark in Serbian language and general school achievement of pupils correlate only with the degree of adhering to the orthographic rules. It was concluded that not only individual programs of support for pupils who make more errors are necessary, but also launching national projects for the development of linguistic competence of the young in Serbia.

Oral and written language in late adulthood: findings from the Nun Study.

Science.gov (United States)

Mitzner, Tracy L; Kemper, Susan

2003-01-01

As a part of the Nun Study, a longitudinal investigation of aging and Alzheimer's disease, oral and written autobiographies from 118 older women were analyzed to examine the relationship between spoken and written language. The written language samples were more complex than the oral samples, both conceptually and grammatically. The relationship between the linguistic measures and participant characteristics was also examined. The results suggest that the grammatical and conceptual characteristics of oral and written language are affected by participant differences in education, cognitive status, and physical function and that written language samples have greater power than oral language samples to differentiate between high- and low-ability older adults.

Written cohesion in children with and without language learning disabilities.

Science.gov (United States)

Koutsoftas, Anthony D; Petersen, Victoria

2017-09-01

Cohesion refers to the linguistic elements of discourse that contribute to its continuity and is an important element to consider as part of written language intervention, especially in children with language learning disabilities (LLD). There is substantial evidence that children with LLD perform more poorly than typically developing (TD) peers on measures of cohesion in spoken language and on written transcription measures; however, there is far less research comparing groups on cohesion as a measure of written language across genres. The current study addresses this gap through the following two aims. First, to describe and compare cohesion in narrative and expository writing samples of children with and without language learning disabilities. Second, to relate measures of cohesion to written transcription and translation measures, oral language, and writing quality. Fifty intermediate-grade children produced one narrative and one expository writing sample from which measures of written cohesion were obtained. These included the frequency, adequacy and complexity of referential and conjunctive ties. Expository samples resulted in more complex cohesive ties and children with TD used more complex ties than peers with LLD. Different relationships among cohesion measures and writing were observed for narrative verse expository samples. Findings from this study demonstrate cohesion as a discourse-level measure of written transcription and how the use of cohesion can vary by genre and group (LLD, TD). Clinical implications for assessment, intervention, and future research are provided. © 2016 Royal College of Speech and Language Therapists.

Full Text Available Abstract: This article is based on the study on the model written texts provided in the Senior High School English textbooks. It is aimed at finding out whether those models are written by considering the English two contexts, cultural and situational, which encircle them. The data are all written texts provided in the six recommended English textbooks published by six different publishers. The results reveal that only eleven out of 115 model written texts tend to be incompatible with the two contexts encircling them, this implies that 104 of them (93.43% are likely to be compatible and can be used as model texts.

Fallon, Karen A; Katz, Lauren A

2011-01-01

The current study was conducted to investigate the provision of written language services by school-based speech-language pathologists (SLPs). Specifically, the study examined SLPs' knowledge, attitudes, and collaborative practices in the area of written language services as well as the variables that impact provision of these services. Public school-based SLPs from across the country were solicited for participation in an online, Web-based survey. Data from 645 full-time SLPs from 49 states were evaluated using descriptive statistics and logistic regression. Many school-based SLPs reported not providing any services in the area of written language to students with written language weaknesses. Knowledge, attitudes, and collaborative practices were mixed. A logistic regression revealed three variables likely to predict high levels of service provision in the area of written language. Data from the current study revealed that many struggling readers and writers on school-based SLPs' caseloads are not receiving services from their SLPs. Implications for SLPs' preservice preparation, continuing education, and doctoral preparation are discussed.

Promotion of a written narratives production program in the third grade of an Elementary School. To analyze two written narrative practice proposals in order to verify which resources are more efficient in benefitting the textual productions of third grade Elementary School students. Sixty students were selected from two third grade groups of a public Elementary School in São Paulo (Brazil). For the analysis, students were divided into two groups (Group A and Group B). Fourteen children's storybooks were used. In Group A, the story was orally told by the researchers in a colloquial manner, keeping the narrator role and the original structure proposed by the author. In Group B, the story was fully read. The book was projected onto a screen and read aloud so the students could follow the reading and observe the corresponding illustrations. Voice changing resources in the characters' dialogues were used. In the overall comparison, statistically significant results were found for moment (initial and final assessments) and for interaction between groups. It was observed that both groups presented substantial development from initial to final assessment. The Written Narratives Promotion Program based on the shared reading of children's storybooks constituted a more effective strategy than telling the stories using a single reader.

Reflection, Interrogatory, Provocation

International Nuclear Information System (INIS)

Carnes, W.E.

2016-01-01

This invited paper advances a framing context for considering next steps in HOF and organizational culture in light of the presentations and discussions that occur during the conference. Many of the contributions during the conference will represent results of scholarly research, structured investigations, or formal organizational improvement efforts. This contribution is intended as informal reflection by a 40-year nuclear veteran on themes from other presentations considering questions such as: ''Where do we think we are?, Are we better off as an industry based on what we have done?, Where do we think we need to go?, What do we think we need to do?, and, Why do we think these things?'' Our coming together on this occasion marks 30 years since the publication of INSAG-l. As we reflect on the past, perhaps it is time to pose a series of questions. Are we sustainers of a mature technology that is in some places declining and being replaced by other energy sources? If we consider nuclear a mature technology, should we focus most on operational excellence with renewed attention to managing the unexpected? Or, is innovation still a vital part of our industry?

Attending evaluations are commonly used to evaluate residents. Evaluate the quality of written feedback of internal medicine residents. Retrospective. Internal medicine residents and faculty at the Medical College of Wisconsin from 2004 to 2012. From monthly evaluations of residents by attendings, a randomly selected sample of 500 written comments by attendings were qualitatively coded and rated as high-, moderate-, or low-quality feedback by two independent coders with good inter-rater reliability (kappa: 0.94). Small group exercises with residents and attendings also coded the utterances as high, moderate, or low quality and developed criteria for this categorization. In-service examination scores were correlated with written feedback. There were 228 internal medicine residents who had 6,603 evaluations by 334 attendings. Among 500 randomly selected written comments, there were 2,056 unique utterances: 29% were coded as nonspecific statements, 20% were comments about resident personality, 16% about patient care, 14% interpersonal communication, 7% medical knowledge, 6% professionalism, and 4% each on practice-based learning and systems-based practice. Based on criteria developed by group exercises, the majority of written comments were rated as moderate quality (65%); 22% were rated as high quality and 13% as low quality. Attendings who provided high-quality feedback rated residents significantly lower in all six of the Accreditation Council for Graduate Medical Education (ACGME) competencies (p service examination scores. Most attending written evaluation was of moderate or low quality. Attendings who provided high-quality feedback appeared to be more discriminating, providing significantly lower ratings of residents in all six ACGME core competencies, and across a greater range. Attendings' negative written comments on medical knowledge correlated with lower in-service training scores.

Global Tsunami Database: Adding Geologic Deposits, Proxies, and Tools

Science.gov (United States)

Brocko, V. R.; Varner, J.

2007-12-01

A result of collaboration between NOAA's National Geophysical Data Center (NGDC) and the Cooperative Institute for Research in the Environmental Sciences (CIRES), the Global Tsunami Database includes instrumental records, human observations, and now, information inferred from the geologic record. Deep Ocean Assessment and Reporting of Tsunamis (DART) data, historical reports, and information gleaned from published tsunami deposit research build a multi-faceted view of tsunami hazards and their history around the world. Tsunami history provides clues to what might happen in the future, including frequency of occurrence and maximum wave heights. However, instrumental and written records commonly span too little time to reveal the full range of a region's tsunami hazard. The sedimentary deposits of tsunamis, identified with the aid of modern analogs, increasingly complement instrumental and human observations. By adding the component of tsunamis inferred from the geologic record, the Global Tsunami Database extends the record of tsunamis backward in time. Deposit locations, their estimated age and descriptions of the deposits themselves fill in the tsunami record. Tsunamis inferred from proxies, such as evidence for coseismic subsidence, are included to estimate recurrence intervals, but are flagged to highlight the absence of a physical deposit. Authors may submit their own descriptions and upload digital versions of publications. Users may sort by any populated field, including event, location, region, age of deposit, author, publication type (extract information from peer reviewed publications only, if you wish), grain size, composition, presence/absence of plant material. Users may find tsunami deposit references for a given location, event or author; search for particular properties of tsunami deposits; and even identify potential collaborators. Users may also download public-domain documents. Data and information may be viewed using tools designed to extract and

[Alcohol advertising in written mass media in Spain].

Montes-Santiago, J; Alvarez Muñiz, M L; Baz Lomba, A

2007-03-01

Alcohol advertising is a powerful factor of incitation to consumption. We analyzed the alcohol advertising, especially that youth-focused, in written mass media in Spain during the period 2002-2006. Annual cross-sectional study of advertisements in 41 widely difused written mass media (average readers: 10,1 millions). Media admitting alcohol publicity were 29% in the whole. (2,9 millions of readers on average, 29% of total readers). Alcohol advertising constituted the 3,8% of global publicity and the 8,6% of the publicity in media admitting alcohol publicity. In this period only 4% of the media (2,4% of total readers) inserted antidrug campaigns. In brief, three out of 10 total readers and one out of 12 people older than 15 years suffered the impact of tobacco advertising. Young people were included in 33% of alcohol advertisements and 3 out of 6 of youth-oriented magazines permitted a such publicity. Alcohol publicity remains high in written mass media in Spain. By contrast few people received informative antidrug campaigns. Advertising was preferentially directed to young people.

Promoting Strong Written Communication Skills

Science.gov (United States)

Narayanan, M.

2015-12-01

The reason that an improvement in the quality of technical writing is still needed in the classroom is due to the fact that universities are facing challenging problems not only on the technological front but also on the socio-economic front. The universities are actively responding to the changes that are taking place in the global consumer marketplace. Obviously, there are numerous benefits of promoting strong written communication skills. They can be summarized into the following six categories. First, and perhaps the most important: The University achieves learner satisfaction. The learner has documented verbally, that the necessary knowledge has been successfully acquired. This results in learner loyalty that in turn will attract more qualified learners.Second, quality communication lowers the cost per pupil, consequently resulting in increased productivity backed by a stronger economic structure and forecast. Third, quality communications help to improve the cash flow and cash reserves of the university. Fourth, having high quality communication enables the university to justify the need for high costs of tuition and fees. Fifth, better quality in written communication skills result in attracting top-quality learners. This will lead to happier and satisfied learners, not to mention greater prosperity for the university as a whole. Sixth, quality written communication skills result in reduced complaints, thus meaning fewer hours spent on answering or correcting the situation. The University faculty and staff are thus able to devote more time on scholarly activities, meaningful research and productive community service. References Boyer, Ernest L. (1990).

Prosodic Parallelism – comparing spoken and written language

Directory of Open Access Journals (Sweden)

Richard Wiese

2016-10-01

Full Text Available The Prosodic Parallelism hypothesis claims adjacent prosodic categories to prefer identical branching of internal adjacent constituents. According to Wiese and Speyer (2015, this preference implies feet contained in the same phonological phrase to display either binary or unary branching, but not different types of branching. The seemingly free schwa-zero alternations at the end of some words in German make it possible to test this hypothesis. The hypothesis was successfully tested by conducting a corpus study which used large-scale bodies of written German. As some open questions remain, and as it is unclear whether Prosodic Parallelism is valid for the spoken modality as well, the present study extends this inquiry to spoken German. As in the previous study, the results of a corpus analysis recruiting a variety of linguistic constructions are presented. The Prosodic Parallelism hypothesis can be demonstrated to be valid for spoken German as well as for written German. The paper thus contributes to the question whether prosodic preferences are similar between the spoken and written modes of a language. Some consequences of the results for the production of language are discussed.

DISCOURSE AND PARTICIPATION IN ESL FACE-TO-FACE AND WRITTEN ELECTRONIC CONFERENCES

Directory of Open Access Journals (Sweden)

Michael Fitze

2006-01-01

Full Text Available This study was a comparative investigation of face-to-face and written electronic conferences. The participants were advanced English as a second language (hereafter: ESL students. The two types of conferences were compared in terms of textual features and participation. There was no statistically significant difference in the total number of words that students produced in an equivalent amount of time in the two types of conferences. The discourse in written electronic conferences displayed greater lexical range, and students in these conferences produced more discourse demonstrating interactive competence. The statistically significant finding of increased lexical range in written electronic conferences persisted even when the interactive discourse was eliminated from the conference transcripts and the transcripts were reanalyzed. This finding suggests that, during written electronic conferences, students were better able to use and practice a wider range of vocabulary related to the topics. For one of the groups, participation in written electronic conferences was more balanced among students, while for the other group participation was about equally balanced regardless of the conference setting. This last finding came as a surprise and points to a need for further research into variables that might mediate balanced participation in face-to-face and written electronic conferences.

Written argument underlying the Brokdorf verdict

International Nuclear Information System (INIS)

Anon.

1980-01-01

In December 1979, the Schleswig administrative court delivered its judgment (AZ.: 10 A 512/76) against the plaintiffs (four neighbouring communities and nine individuals), who had brought in an action against the first part-construction permit for the Brokdorf nuclear power plant, issued on October 25, 1976. In mid-march 1980, the written argument underlying this court ruling (58 pages) has been sent out. The written argument conscientiously explains the reasoning of the court which delivered its verdict after several days of oral proceedings in October and November 1979, and clearly states the position of the court with regard to the limits of control by administrative jurisdiction as well as to the controversial legal problem of whether there is a lawful connection between the licensing in accordance with section 7, sub-section 2 of the AtG (Atomic Energy Act) and sufficient nuclear waste management provisions according to section 9a AtG. The court ruling declared the action to be substantially admissible but hot well-founded. (orig./HP) [de

The influence of nine variables on the latencies to write down or to speak aloud the names of pictures taken from Snodgrass and Vanderwart (1980) was investigated in French adults. The major determinants of both written and spoken picture naming latencies were image variability, image agreement and age of acquisition. To a lesser extent, name agreement was also found to have an impact in both production modes. The implications of the findings for theoretical views of both spoken and written picture naming are discussed.

How Do Surgery Students Use Written Language to Say What They See? A Framework to Understand Medical Students' Written Evaluations of Their Teachers.

Science.gov (United States)

Lim, David W; White, Jonathan S

2015-11-01

There remains debate regarding the value of the written comments that medical students are traditionally asked to provide to evaluate the teaching they receive. The purpose of this study was to examine written teaching evaluations to understand how medical students conceptualize teachers' behaviors and performance. All written comments collected from medical students about teachers in the two surgery clerkships at the University of Alberta in 2009-2010 and 2010-2011 were collated and anonymized. A grounded theory approach was used for analysis, with iterative reading and open coding to identify recurring themes. A framework capturing variations observed in the data was generated until data saturation was achieved. Domains and subdomains were named using an in situ coding approach. The conceptual framework contained three main domains: "Physician as Teacher," "Physician as Person," and "Physician as Physician." Under "Physician as Teacher," students commented on specific acts of teaching and subjective perceptions of an educator's teaching values. Under the "Physician as Physician" domain, students commented on elements of their educator's physicianship, including communication and collaborative skills, medical expertise, professionalism, and role modeling. Under "Physician as Person," students commented on how both positive and negative personality traits impacted their learning. This framework describes how medical students perceive their teachers and how they use written language to attach meaning to the behaviors they observe. Such a framework can be used to help students provide more constructive feedback to teachers and to assist in faculty development efforts aimed at improving teaching performance.

Salomé Geertsema

2011-01-01

Full Text Available SMS language is English language slang, used as a means of mobile phone text messaging. This practice may impact on the written language skills of learners at school. The main aim of this study was to determine the perspectives of Grade 8 and 9 English (as Home Language educators in Gauteng regarding the possible influence of SMS language on certain aspects of learners' written language skills. If an influence was perceived by the educators, their perceptions regarding the degree and nature of the influence were also explored. A quantitative research design, utilising a questionnaire, was employed. The sample of participants comprised 22 educators employed at independent secondaryschools within Gauteng, South Africa. The results indicated that the majority of educators viewed SMS language as having a negative influence on the written language skills of Grade 8 and 9 learners. The influence was perceived as occurring in the learners' spelling, punctuation, and sentence length. A further finding was that the majority of educators address the negative influences of SMS language when encountered in written tasks.

Consumer Preferences for Written and Oral Information about Allergens When Eating Out.

Science.gov (United States)

Begen, Fiona M; Barnett, Julie; Payne, Ros; Roy, Debbie; Gowland, M Hazel; Lucas, Jane S

2016-01-01

Avoiding food allergens when eating outside the home presents particular difficulties for food allergic (FA) and intolerant (FI) consumers and a lack of allergen information in restaurants and takeaways causes unnecessary restrictions. Across Europe, legislation effective from December 2014, aims to improve allergen information by requiring providers of non-prepacked foods to supply information related to allergen content within their foods. Using in-depth interviews with 60 FA/FI adults and 15 parents/carers of FA/FI children, we aimed to identify FA/FI consumers' preferences for written and/or verbal allergen information when eating out or ordering takeaway food. A complex and dynamic set of preferences and practices for written and verbal allergen information was identified. Overwhelmingly, written information was favoured in the first instance, but credible personal/verbal communication was highly valued and essential to a good eating out experience. Adequate written information facilitated implicit trust in subsequent verbal information. Where written information was limited, FA/FIs depended on social cues to assess the reliability of verbal information resources, and defaulted to tried and tested allergen avoidance strategies when these were deemed unreliable. Understanding the subtle negotiations and difficulties encountered by FA/FIs when eating out can serve as a guide for legislators and food providers; by encouraging provision of clear written and verbal allergen information, and training of proactive, allergen-aware staff. This, in tandem with legal requirements for allergen information provision, paves the way for FA/FIs to feel more confident in eating out choices; and to experience improved eating out experiences.

A new computer code called MATADOR (Methods for the Analysis of Transport And Deposition Of Radionuclides) has been developed to replace the CORRAL-2 computer code which was written for the Reactor Safety Study (WASH-1400). This report is a User's Manual for MATADOR. MATADOR is intended for use in system risk studies to analyze radionuclide transport and deposition in reactor containments. The principal output of the code is information on the timing and magnitude of radionuclide releases to the environment as a result of severely degraded core accidents. MATADOR considers the transport of radionuclides through the containment and their removal by natural deposition and by engineered safety systems such as sprays. It is capable of analyzing the behavior of radionuclides existing either as vapors or aerosols in the containment. The code requires input data on the source terms into the containment, the geometry of the containment, and thermal-hydraulic conditions in the containment

STRATEGIES OF EXPRESSING WRITTEN APOLOGIES IN THE ONLINE NEWSPAPERS

Full Text Available Expressing apology is a universal activity although people have different strategies or ways to express the apology based on the culture, situation, and context. An apology has played a vital role in verbal politeness; it is certainly impolite when someone does not express an apology when he or she has commited an offence to the others. Apologies in the Pragmatic study is classified under speech act theory. An apology based on Searle (1969 is classified as expressive speech acts because it expresses speaker’s physiological attitude. An apology expresses speaker’s sorrow and regret because he/she has offended hearers or readers.  This paper tries to discuss strategies of editors in expressing written apologies in the online newspaper. The objective of this paper is to explain what the strategies of written apologies are in the online newspaper. This study uses qualitative method; the writer chooses descriptive interpretative technique for analyzing data. There are four written apologies in the online neswpapers as data sources in this paper, the data are taken from The Jakarta Post, The Daily Express, The Sun, and Brisbane Times. The writer tries to describe and analyzes utterances in the data sources based on Olshtain & Cohen theory (1986. There are five main strategies in expressing apologies according to Olshtain & Cohen (1986; they are Illocutionary Force Indicating Device (IFID, expression responsibility, explanation/justification, offer repairs, and promise forbearance. The writer found that all of the written apologies used combination strategies, they used IFID by using performative verb: apologize and be sorry then followed by expression resposbility, explanation, offer repairs, and promise forbearance. Keywords: apologies, speech acts, politeness, pragmatics

Modeling statistical properties of written text.

Directory of Open Access Journals (Sweden)

M Angeles Serrano

Full Text Available Written text is one of the fundamental manifestations of human language, and the study of its universal regularities can give clues about how our brains process information and how we, as a society, organize and share it. Among these regularities, only Zipf's law has been explored in depth. Other basic properties, such as the existence of bursts of rare words in specific documents, have only been studied independently of each other and mainly by descriptive models. As a consequence, there is a lack of understanding of linguistic processes as complex emergent phenomena. Beyond Zipf's law for word frequencies, here we focus on burstiness, Heaps' law describing the sublinear growth of vocabulary size with the length of a document, and the topicality of document collections, which encode correlations within and across documents absent in random null models. We introduce and validate a generative model that explains the simultaneous emergence of all these patterns from simple rules. As a result, we find a connection between the bursty nature of rare words and the topical organization of texts and identify dynamic word ranking and memory across documents as key mechanisms explaining the non trivial organization of written text. Our research can have broad implications and practical applications in computer science, cognitive science and linguistics.

Factors affecting written distance-learning feedback: the tutor’s perspective

Directory of Open Access Journals (Sweden)

Christine Calfoglou

2011-02-01

Full Text Available Launching the distance-learning student-tutor interaction process, tutors of the first module of the M.Ed in English course at the HOU lay the foundations of academic student autonomy by means of providing – inter alia -- the appropriate written feedback on written assignments. In doing so, they need to gauge the content and form of their written comments systematically with regard to both output- and student-, that is human factor-related issues (cf. Goldstein, 2004, the latter being particularly relevant to the distance-learning context. In this article we discuss tutor policy as well as tutor perceptions (cf. Lee, 2004, 2009 among others regarding written feedback on students’ academic assignments in terms of aspects of deviance treated and the relative gravity of ‘global’ and ‘local’ errors (e.g. Ferris, 2002, the directness of the correction, the punitive or facilitative nature of the comments provided as well as the relative balance of student strengths and weaknesses on the tutor’s comment agenda (cf. Hyland & Hyland, 2006. The role of the tutor as an assessor and/or counsellor is explored and the importance of striking a delicate balance between the two, especially in a context where face-to-face feedback opportunities are severely restricted, is underscored. We suggest that distance-learning feedback practices may need to be at least partially individualized to maximize student response and meet the goal of ‘informed autonomy’.

Speech language therapy bilingual clinic, a written language therapeutical proposal to deaf people: case report.

Science.gov (United States)

Guarinello, Ana Cristina; Massi, Giselle; Berberian, Ana Paula; Tonocchi, Rita; Lustosa, Sandra Silva

2015-01-01

This study aimed to analyze the written production of a deaf person who is in the process of written language acquisition. One person with hearing disability, called R., participated in this study together with his Speech Language Pathologist. The therapist, proficient in sign language, acted as an interlocutor and interpreter, prioritizing the interactive nature of language and interfering in the written production only when it was requested. During the 3 years of work with R., a change in stance toward written language was observed. In addition, he began to reflect on his texts and utilize written Portuguese in a way that allowed his texts to be more coherent. Writing became an opportunity to show his singularity and to begin reconstructing his relationship with language. Speech language pathology and audiology therapy, at a bilingual clinic, can allow people with hearing disability early access to sign language and, consequently, enable the development of the written form of Portuguese.

THE HISTORY OF EXPLORATION AND EXPLOITATION OF BITUMINOUS AND KEROGENOUS DEPOSITS IN CROATIA

Directory of Open Access Journals (Sweden)

Berislav Šebečić

1995-12-01

Full Text Available It is assumed thal the first known sedimens of natural bitumen or asphalt in coastal Croatia were exploited as the early moddle ages. Yet authenticated written documents about Vinišće near Trogir derive from no earlier than 1628, about Vrgorac/Paklina from only 1753. By the end of the 18th century, many deposits were discovered in Dalmatia, but it was Škrip on the Island of Brač and Suhi Dolac that were important. The earliest known deposits and occurrences of kerogenous rocks, or bituminous or oil shales, are mentioned as stone or fossil coal in Sovinjak, in the upper course of the River Mirna, and in Rebići in Istria; near Sinj, Slivno not far from the River Neretva, Mirta and near Nerežišće on the Island uf Brač. All if these were well known and described in 1804, while Sovinjak was mentioned in the 16th century. In the article, some of new information derived from mining and geological research into bituminous and kerogenous sediments and deposits are provided (the paper is published in Croatian.

One-Dimensional Signal Extraction Of Paper-Written ECG Image And Its Archiving

Science.gov (United States)

Zhang, Zhi-ni; Zhang, Hong; Zhuang, Tian-ge

1987-10-01

A method for converting paper-written electrocardiograms to one dimensional (1-D) signals for archival storage on floppy disk is presented here. Appropriate image processing techniques were employed to remove the back-ground noise inherent to ECG recorder charts and to reconstruct the ECG waveform. The entire process consists of (1) digitization of paper-written ECGs with an image processing system via a TV camera; (2) image preprocessing, including histogram filtering and binary image generation; (3) ECG feature extraction and ECG wave tracing, and (4) transmission of the processed ECG data to IBM-PC compatible floppy disks for storage and retrieval. The algorithms employed here may also be used in the recognition of paper-written EEG or EMG and may be useful in robotic vision.

The Contribution of Verbal Working Memory to Deaf Children’s Oral and Written Production

Science.gov (United States)

Arfé, Barbara; Rossi, Cristina; Sicoli, Silvia

2015-01-01

This study investigated the contribution of verbal working memory to the oral and written story production of deaf children. Participants were 29 severely to profoundly deaf children aged 8–13 years and 29 hearing controls, matched for grade level. The children narrated a picture story orally and in writing and performed a reading comprehension test, the Wechsler Intelligence Scale for Children-Fourth Edition forward digit span task, and a reading span task. Oral and written stories were analyzed at the microstructural (i.e., clause) and macrostructural (discourse) levels. Hearing children’s stories scored higher than deaf children’s at both levels. Verbal working memory skills contributed to deaf children’s oral and written production over and above age and reading comprehension skills. Verbal rehearsal skills (forward digit span) contributed significantly to deaf children’s ability to organize oral and written stories at the microstructural level; they also accounted for unique variance at the macrostructural level in writing. Written story production appeared to involve greater verbal working memory resources than oral story production. PMID:25802319

Written object naming, spelling to dictation, and immediate copying: Different tasks, different pathways?

Science.gov (United States)

Bonin, Patrick; Méot, Alain; Lagarrigue, Aurélie; Roux, Sébastien

2015-01-01

We report an investigation of cross-task comparisons of handwritten latencies in written object naming, spelling to dictation, and immediate copying. In three separate sessions, adults had to write down a list of concrete nouns from their corresponding pictures (written naming), from their spoken (spelling to dictation) and from their visual presentation (immediate copying). Linear mixed models without random slopes were performed on the latencies in order to study and compare within-task fixed effects. By-participants random slopes were then included to investigate individual differences within and across tasks. Overall, the findings suggest that written naming, spelling to dictation, and copying all involve a lexical pathway, but that written naming relies on this pathway more than the other two tasks do. Only spelling to dictation strongly involves a nonlexical pathway. Finally, the analyses performed at the level of participants indicate that, depending on the type of task, the slower participants are more or less influenced by certain psycholinguistic variables.

Modality differences between written and spoken story retelling in healthy older adults

Directory of Open Access Journals (Sweden)

Jessica Ann Obermeyer

2015-04-01

Methods: Ten native English speaking healthy elderly participants between the ages of 50 and 80 were recruited. Exclusionary criteria included neurological disease/injury, history of learning disability, uncorrected hearing or vision impairment, history of drug/alcohol abuse and presence of cognitive decline (based on Cognitive Linguistic Quick Test. Spoken and written discourse was analyzed for micro linguistic measures including total words, percent correct information units (CIUs; Nicholas & Brookshire, 1993 and percent complete utterances (CUs; Edmonds, et al. 2009. CIUs measure relevant and informative words while CUs focus at the sentence level and measure whether a relevant subject and verb and object (if appropriate are present. Results: Analysis was completed using Wilcoxon Rank Sum Test due to small sample size. Preliminary results revealed that healthy elderly people produced significantly more words in spoken retellings than written retellings (p=.000; however, this measure contrasted with %CIUs and %CUs with participants producing significantly higher %CIUs (p=.000 and %CUs (p=.000 in written story retellings than in spoken story retellings. Conclusion: These findings indicate that written retellings, while shorter, contained higher accuracy at both a word (CIU and sentence (CU level. This observation could be related to the ability to revise written text and therefore make it more concise, whereas the nature of speech results in more embellishment and “thinking out loud,” such as comments about the task, associated observations about the story, etc. We plan to run more participants and conduct a main concepts analysis (before conference time to gain more insight into modality differences and implications.

Comparison of self-written waveguide techniques and bulk index matching for low-loss polymer waveguide interconnects

Science.gov (United States)

Burrell, Derek; Middlebrook, Christopher

2016-03-01

Polymer waveguides (PWGs) are used within photonic interconnects as inexpensive and versatile substitutes for traditional optical fibers. The PWGs are typically aligned to silica-based optical fibers for coupling. An epoxide elastomer is then applied and cured at the interface for index matching and rigid attachment. Self-written waveguides (SWWs) are proposed as an alternative to further reduce connection insertion loss (IL) and alleviate marginal misalignment issues. Elastomer material is deposited after the initial alignment, and SWWs are formed by injecting ultraviolet (UV) light into the fiber or waveguide. The coupled UV light cures a channel between the two differing structures. A suitable cladding layer can be applied after development. Such factors as longitudinal gap distance, UV cure time, input power level, polymer material selection and choice of solvent affect the resulting SWWs. Experimental data are compared between purely index-matched samples and those with SWWs at the fiber-PWG interface. It is shown that writing process. Successfully fabricated SWWs reduce overall processing time and enable an effectively continuous low-loss rigid interconnect.

Marginalia as the beginning of written culture: The Glosas Emilianensis

Directory of Open Access Journals (Sweden)

Maja Šabec

2010-12-01

Full Text Available The Glosas emilianenses are notes in Latin and in a Romance language dating from the eleventh century, written by an anonymous monk between the lines and in the margins of a Latin manuscript known as Codex Aemilianensis 60 to explicate syntactic, morphological, and semantic difficulties in understanding the original. The document was named after its place of origin, a monastery in the village of San Millán de la Cogolla, known as “the cradle of Castilian.” The non-Latin Romance glosses are believed to be the first written accounts of the language that later evolved into present-day Castilian or Spanish; they are therefore invaluable historical, linguistic, literary, and cultural material. The place and time of the origin of the glosses are not a coincidence, but a consequence of particular historical circumstances in the Iberian Peninsula. The Moorish invasion in 711 AD destroyed the Visigothic Kingdom and constrained the development of Christian culture, confining it to two independent cores in the north. The ninth century therefore saw the establishment of the County of Castile emerging from the two cores as the predecessor of the Kingdom of Castile (1065. Due to turbulent historical events, the place was populated by people from various adjacent and rather distant countries, thus making the spoken language a mixture of several varieties of Vulgar Latin, Mozarabic, and Navarrian (Basque elements. All of these features are reflected in the glosses in the San Millán manuscript. Therefore, it is difficult for linguists to name the variant of the Romance language the glosses were written in: “the Riojan dialect,” “a vernacular Castilian-Riojan dialect of the second half of the eleventh century displaying tendencies towards learned Latin,” or “a Riojan dialect with elements more common to neighboring dialects (Aragon, Navarrian, Léon, and Mozarabic than to Castilian.” However, because the San Millán glosses also include elements

Evaluation of written patient educational materials in the field of diagnostic imaging

International Nuclear Information System (INIS)

Ryhaenen, A.M.; Johansson, K.; Virtanen, H.; Salo, S.; Salanterae, S.; Leino-Kilpi, H.

2009-01-01

Aim: To evaluate the quality of written educational materials for diagnostic imaging (radiological and nuclear medicine) patients. Materials and methods: Written educational materials (n = 70) for diagnostic imaging patients were analysed. The materials were evaluated based on their external appearance (9 criteria), instructiveness (7), content (7), language and structure (8) and readability (1). Deductive content analysis was used. Quantified parts of the analyses were analysed by SAS for Windows. Dependence between criteria (32) was tested by Pearson correlation coefficients. Results: The external appearance fulfilled almost completely the criteria of good written education materials. The instructiveness was addressed clearly, except for the purpose of the material. The contents of materials dealt with bio-physiological, functional and cognitive dimensions of knowledge, while financial dimensions of knowledge were hardly dealt with at all. The language and the structure were reasonably good, but the language was partly in passive voice and the text contained strange words. Most of the education material was moderately easy to read. Conclusions: The results show that the quality of material was quite good in all dimensions. Only a small number of criteria were unsatisfactory. The results can be used to further improve written patient education materials and patient education in the imaging unit.

Electrophoretic Deposition of Gallium with High Deposition Rate

Directory of Open Access Journals (Sweden)

Hanfei Zhang

2014-12-01

Full Text Available In this work, electrophoretic deposition (EPD is reported to form gallium thin film with high deposition rate and low cost while avoiding the highly toxic chemicals typically used in electroplating. A maximum deposition rate of ~0.6 μm/min, almost one order of magnitude higher than the typical value reported for electroplating, is obtained when employing a set of proper deposition parameters. The thickness of the film is shown to increase with deposition time when sequential deposition is employed. The concentration of Mg(NO32, the charging salt, is also found to be a critical factor to control the deposition rate. Various gallium micropatterns are obtained by masking the substrate during the process, demonstrating process compatibility with microfabrication. The reported novel approach can potentially be employed in a broad range of applications with Ga as a raw material, including microelectronics, photovoltaic cells, and flexible liquid metal microelectrodes.

Fabrication of self-written waveguide in photosensitive polyimide resin by controlling photochemical reaction of photosensitizer

International Nuclear Information System (INIS)

Yamashita, K.; Kuro, T.; Oe, K.; Mune, K.; Tagawa, K.; Naitou, R.; Mochizuki, A.

2004-01-01

We have investigated optical properties of photosensitive polyimide appropriating for long self-written waveguide fabrication. From systematic measurements of absorption properties, it was found that photochemical reaction of photosensitizer dissolved in the photosensitive polyimide resins relates to transparency after the exposure, which limits the length of the fabricated self-written waveguide. By controlling the photochemical reaction, in which the photosensitive polyimide resin has sufficient transparency during exposure, four times longer self-written waveguide core was fabricated

Applying George Lakoff and Mark Johnson’s approach to metaphor, the paper attempts to determine both the kind of source domains from which common metaphors are drawn and to what degree structural metaphors are used. The data suggests that many structural metaphors can be found in the language of politics. They are drawn from a wide variety of sports source domains, although the domains of boxing, racing, sailing, and soccer are of particular prominence. It seems that the primary function of structural metaphors in written commentaries is to facilitate the interpretation of facts in a way that is enormously appealing to the reader.

Attitudes of second language students towards self-editing their own written texts

Directory of Open Access Journals (Sweden)

Daniel Kasule

2010-05-01

Full Text Available Recognizing students’ deliberate e!orts to minimize errors in their written texts is valuable in seeing them as responsible active agents in text creation. This paper reports on a brief survey of the attitudes towards self-editing of seventy university students using a questionnaire and class discussion. The context of the study is characterized by its emphasis on evaluating the finished written product. Findings show that students appreciate the role of self-editing in minimizing errors in their texts and that it helps in eventually producing well-written texts. Conceptualizing writing as discourse and therefore as social practice leads to an understanding of writers as socially-situated actors; repositions the student writer as an active agent in text creation; and is central to student-centred pedagogy. We recommend the recognition of self-editing as a vital element in the writing process and that additional error detection mechanisms namely peers, the lecturer, and the computer, increase student autonomy.

Enhancing the benefits of written emotional disclosure through response training.

Konig, Andrea; Eonta, Alison; Dyal, Stephanie R; Vrana, Scott R

2014-05-01

Writing about a personal stressful event has been found to have psychological and physical health benefits, especially when physiological response increases during writing. Response training was developed to amplify appropriate physiological reactivity in imagery exposure. The present study examined whether response training enhances the benefits of written emotional disclosure. Participants were assigned to either a written emotional disclosure condition (n=113) or a neutral writing condition (n=133). Participants in each condition wrote for 20 minutes on 3 occasions and received response training (n=79), stimulus training (n=84) or no training (n=83). Heart rate and skin conductance were recorded throughout a 10-minute baseline, 20-minute writing, and a 10-minute recovery period. Self-reported emotion was assessed in each session. One month after completing the sessions, participants completed follow-up assessments of psychological and physical health outcomes. Emotional disclosure elicited greater physiological reactivity and self-reported emotion than neutral writing. Response training amplified physiological reactivity to emotional disclosure. Greater heart rate during emotional disclosure was associated with the greatest reductions in event-related distress, depression, and physical illness symptoms at follow-up, especially among response trained participants. Results support an exposure explanation of emotional disclosure effects and are the first to demonstrate that response training facilitates emotional processing and may be a beneficial adjunct to written emotional disclosure.

Whissel, R; Whissel, C

2000-12-01

Lyrics from 155 songs written by the Lennon-McCartney team were scored using the Dictionary of Affect in Language. Resultant scores (pleasantness, activation, and imagery of words) were compared across key signatures using one way analyses of variance. Words from songs written in minor keys were less pleasant and less active than those from songs written in major keys. Words from songs written in the key of F scored extremely low on all three measures. Lyrics from the keys of C, D, and G were relatively active in tone. Results from Dictionary scoring were compared with assignments of character to keys made more than one century ago and with current musicians' opinions.

Full Text Available The approximation of the pragmatic knowledge of English language learners to native speakers has been a realm of concern for the scholars and researchers in applied linguistics. Thus, this research was an endeavor to figure out the association between the proficiency level and politeness strategies and external/internal modifications in written communication skills in the speech act of requests in Iranian English language learners. To this end, a written Discourse Completion Test (DCT, adapted from Rose (1994, including 8 situations was administered to elicit data from Iran Language Institute120 female and male EFL learners, 60 upper-intermediate and 60 intermediate. The data were sorted out using Brown and Levinson’s politeness strategies taxonomy (Brown and Levinson 1987 and external/internal modifications developed by Faerch and Kasper (1989. The written request utterances provided by each participant were analyzed in terms of frequency and types of politeness strategies, namely, positive, negative, bald on record, and off-record as well as external/internal modifications utilized in requests. The Pearson Chi-Square test results revealed that there was a statistically significant difference between upper-intermediate and intermediate learners’ type of politeness strategies and external/internal modifications.

A Large-Scale Analysis of Variance in Written Language.

Science.gov (United States)

Johns, Brendan T; Jamieson, Randall K

2018-01-22

The collection of very large text sources has revolutionized the study of natural language, leading to the development of several models of language learning and distributional semantics that extract sophisticated semantic representations of words based on the statistical redundancies contained within natural language (e.g., Griffiths, Steyvers, & Tenenbaum, ; Jones & Mewhort, ; Landauer & Dumais, ; Mikolov, Sutskever, Chen, Corrado, & Dean, ). The models treat knowledge as an interaction of processing mechanisms and the structure of language experience. But language experience is often treated agnostically. We report a distributional semantic analysis that shows written language in fiction books varies appreciably between books from the different genres, books from the same genre, and even books written by the same author. Given that current theories assume that word knowledge reflects an interaction between processing mechanisms and the language environment, the analysis shows the need for the field to engage in a more deliberate consideration and curation of the corpora used in computational studies of natural language processing.

Harl, Felicity N R; Saucke, Megan C; Greenberg, Caprice C; Ingraham, Angela M

2017-06-15

Poor communication causes fragmented care. Studies of transitions of care within a hospital and on discharge suggest significant communication deficits. Communication during transfers between hospitals has not been well studied. We assessed the written communication provided during interhospital transfers of emergency general surgery patients. We hypothesized that patients are transferred with incomplete documentation from referring facilities. We performed a retrospective review of written communication provided during interhospital transfers to our emergency department (ED) from referring EDs for emergency general surgical evaluation between January 1, 2014 and January 1, 2016. Elements of written communication were abstracted from referring facility documents scanned into the medical record using a standardized abstraction protocol. Descriptive statistics summarized the information communicated. A total of 129 patients met inclusion criteria. 87.6% (n = 113) of charts contained referring hospital documents. 42.5% (n = 48) were missing history and physicals. Diagnoses were missing in 9.7% (n = 11). Ninety-one computed tomography scans were performed; among 70 with reads, final reads were absent for 70.0% (n = 49). 45 ultrasounds and x-rays were performed; among 27 with reads, final reads were missing for 80.0% (n = 36). Reasons for transfer were missing in 18.6% (n = 21). Referring hospital physicians outside the ED were consulted in 32.7% (n = 37); consultants' notes were absent in 89.2% (n = 33). In 12.4% (n = 14), referring documents arrived after the patient's ED arrival and were not part of the original documentation provided. This study documents that information important to patient care is often missing in the written communication provided during interhospital transfers. This gap affords a foundation for standardizing provider communication during interhospital transfers. Copyright © 2017 Elsevier Inc. All rights reserved.

Cobalt—Styles of deposits and the search for primary deposits

Science.gov (United States)

Hitzman, Murray W.; Bookstrom, Arthur A.; Slack, John F.; Zientek, Michael L.

2017-11-30

Cobalt (Co) is a potentially critical mineral. The vast majority of cobalt is a byproduct of copper and (or) nickel production. Cobalt is increasingly used in magnets and rechargeable batteries. More than 50 percent of primary cobalt production is from the Central African Copperbelt. The Central African Copperbelt is the only sedimentary rock-hosted stratiform copper district that contains significant cobalt. Its presence may indicate significant mafic-ultramafic rocks in the local basement. The balance of primary cobalt production is from magmatic nickel-copper and nickel laterite deposits. Cobalt is present in several carbonate-hosted lead-zinc and copper districts. It is also variably present in Besshi-type volcanogenic massive sulfide and siliciclastic sedimentary rock-hosted deposits in back arc and rift environments associated with mafic-ultramafic rocks. Metasedimentary cobalt-copper-gold deposits (such as Blackbird, Idaho), iron oxide-copper-gold deposits, and the five-element vein deposits (such as Cobalt, Ontario) contain different amounts of cobalt. None of these deposit types show direct links to mafic-ultramafic rocks; the deposits may result from crustal-scale hydrothermal systems capable of leaching and transporting cobalt from great depths. Hydrothermal deposits associated with ultramafic rocks, typified by the Bou Azzer district of Morocco, represent another type of primary cobalt deposit.In the United States, exploration for cobalt deposits may focus on magmatic nickel-copper deposits in the Archean and Proterozoic rocks of the Midwest and the east coast (Pennsylvania) and younger mafic rocks in southeastern and southern Alaska; also, possibly basement rocks in southeastern Missouri. Other potential exploration targets include—The Belt-Purcell basin of British Columbia (Canada), Idaho, Montana, and Washington for different styles of sedimentary rock-hosted cobalt deposits;Besshi-type VMS deposits, such as the Greens Creek (Alaska) deposit and

Reconsidering Written Language

Directory of Open Access Journals (Sweden)

Gopal P. Sarma

2015-07-01

Full Text Available A number of elite thinkers in Europe during the 16th and 17th centuries pursued an agenda which historian Paolo Rossi calls the “quest for a universal language,” a quest which was deeply interwoven with the emergence of the scientific method. From a modern perspective, one of the many surprising aspects of these efforts is that they relied on a diverse array of memorization techniques as foundational elements. In the case of Leibniz’s universal calculus, the ultimate vision was to create a pictorial language that could be learned by anyone in a matter of weeks and which would contain within it a symbolic representation of all domains of contemporary thought, ranging from the natural sciences, to theology, to law. In this brief article, I explore why this agenda might have been appealing to thinkers of this era by examining ancient and modern memory feats. As a thought experiment, I suggest that a society built entirely upon memorization might be less limited than we might otherwise imagine, and furthermore, that cultural norms discouraging the use of written language might have had implications for the development of scientific methodology. Viewed in this light, the efforts of Leibniz and others seem significantly less surprising. I close with some general observations about cross-cultural origins of scientific thought.

MESOI Version 2.0: an interactive mesoscale Lagrangian puff dispersion model with deposition and decay

International Nuclear Information System (INIS)

Ramsdell, J.V.; Athey, G.F.; Glantz, C.S.

1983-11-01

MESOI Version 2.0 is an interactive Lagrangian puff model for estimating the transport, diffusion, deposition and decay of effluents released to the atmosphere. The model is capable of treating simultaneous releases from as many as four release points, which may be elevated or at ground-level. The puffs are advected by a horizontal wind field that is defined in three dimensions. The wind field may be adjusted for expected topographic effects. The concentration distribution within the puffs is initially assumed to be Gaussian in the horizontal and vertical. However, the vertical concentration distribution is modified by assuming reflection at the ground and the top of the atmospheric mixing layer. Material is deposited on the surface using a source depletion, dry deposition model and a washout coefficient model. The model also treats the decay of a primary effluent species and the ingrowth and decay of a single daughter species using a first order decay process. This report is divided into two parts. The first part discusses the theoretical and mathematical bases upon which MESOI Version 2.0 is based. The second part contains the MESOI computer code. The programs were written in the ANSI standard FORTRAN 77 and were developed on a VAX 11/780 computer. 43 references, 14 figures, 13 tables

Examining the central and peripheral processes of written word production through meta-analysis

Directory of Open Access Journals (Sweden)

Jeremy ePurcell

2011-10-01

Full Text Available Producing written words requires central cognitive processes (such as orthographic long-term and working memory as well as more peripheral processes responsible for generating the motor actions needed for producing written words in a variety of formats (handwriting, typing, etc.. In recent years, various functional neuroimaging studies have examined the neural substrates underlying the central and peripheral processes of written word production. This study provides the first quantitative meta-analysis of these studies by applying Activation Likelihood Estimation methods (Turkeltaub et al., 2002. For alphabet languages, we identified 11 studies (with a total of 17 experimental contrasts that had been designed to isolate central and/or peripheral processes of word spelling (total number of participants = 146. Three ALE meta-analyses were carried out. One involved the complete set of 17 contrasts; two others were applied to subsets of contrasts to distinguish the neural substrates of central from peripheral processes. These analyses identified a network of brain regions reliably associated with the central and peripheral processes of word spelling. Among the many significant results, is the finding that the regions with the greatest correspondence across studies were in the left inferior temporal/fusiform gyri and left inferior frontal gyrus. Furthermore, although the angular gyrus has traditionally been identified as a key site within the written word production network, none of the meta-analyses found it to be a consistent site of activation, identifying instead a region just superior/medial to the left angular gyrus in the left posterior intraparietal sulcus. In general these meta-analyses and the discussion of results provide a valuable foundation upon which future studies that examine the neural basis of written word production can build.

Written and verbal communication skills are important skills for all physicians. While verbal skills are taught and assessed in medical school, medical students report limited instruction in written communication skills. This study examined the impact of a curriculum delivered during a 6-week clinical rotation in Internal Medicine on the objective assessment of medical students' written communication skills. The curriculum consisted of two educational programmes: a medical student communication tutorial and a resident feedback workshop. The study was conducted from March 2012 to January 2013 at McMaster University in Hamilton, Ontario, Canada. The study featured three arms: (1) control, (2) medical student communication tutorial alone and (3) student tutorial and resident feedback workshop. Data were collected on 126 students during 6-week Internal Medicine clerkship rotations. Students' written consultation notes were collected prior to the educational programmes and at 6 weeks. Blinded faculty assessors used an independently validated Assessment Checklist to evaluate consultation notes. Consultation note scores improved from week 1 to week 6 across all study arms. However, the change was statistically significant only in arm 3, featuring both the medical student tutorial and the resident feedback workshop, with mean scores improving from 4.75 (SD=1.496) to 5.56 (SD=0.984) out of 7. The mean difference between week 1 and week 6 was significantly different (0.806, p=0.002, 95% CI 0.306 to 1.058). The combination of a resident feedback workshop with medical student written communication tutorial improves objective evaluations of consultation note scores over student tutorial alone.

Lemiengre, Joke; Dierckx de Casterlé, Bernadette; Schotsmans, Paul; Gastmans, Chris

2014-05-01

As euthanasia has become a widely debated issue in many Western countries, hospitals and nursing homes especially are increasingly being confronted with this ethically sensitive societal issue. The focus of this paper is how healthcare institutions can deal with euthanasia requests on an organizational level by means of a written institutional ethics policy. The general aim is to make a critical analysis whether these policies can be considered as organizational-ethical instruments that support healthcare institutions to take their institutional responsibility for dealing with euthanasia requests. By means of an interpretative analysis, we conducted a process of reinterpretation of results of former Belgian empirical studies on written institutional ethics policies on euthanasia in dialogue with the existing international literature. The study findings revealed that legal regulations, ethical and care-oriented aspects strongly affected the development, the content, and the impact of written institutional ethics policies on euthanasia. Hence, these three cornerstones-law, care and ethics-constituted the basis for the empirical-based organizational-ethical framework for written institutional ethics policies on euthanasia that is presented in this paper. However, having a euthanasia policy does not automatically lead to more legal transparency, or to a more professional and ethical care practice. The study findings suggest that the development and implementation of an ethics policy on euthanasia as an organizational-ethical instrument should be considered as a dynamic process. Administrators and ethics committees must take responsibility to actively create an ethical climate supporting care providers who have to deal with ethical dilemmas in their practice.

Speech-language therapy for adolescents with written-language difficulties: The South African context

Directory of Open Access Journals (Sweden)

Danel Erasmus

2013-11-01

Method: A survey study was conducted, using a self-administered questionnaire. Twenty-two currently practising speech-language therapists who are registered members of the South African Speech-Language-Hearing Association (SASLHA participated in the study. Results: The respondents indicated that they are aware of their role regarding adolescents with written-language difficulties. However, they feel that South-African speech-language therapists are not fulfilling this role. Existing assessment tools and interventions for written-language difficulties are described as inadequate, and culturally and age inappropriate. Yet, the majority of the respondents feel that they are adequately equipped to work with adolescents with written-language difficulties, based on their own experience, self-study and secondary training. The respondents feel that training regarding effective collaboration with teachers is necessary to establish specific roles, and to promote speech-language therapy for adolescents among teachers. Conclusion: Further research is needed in developing appropriate assessment and intervention tools as well as improvement of training at an undergraduate level.

Full Text Available Abstract: This paper examines the written discourse of interviewing style for the purpose of print publication. Specifically, this paper sought to describe and explain the phases of interviewing procedures, the typology of the questions, and the transitional strategies executed by Oprah Winfrey during her interviews for O Magazine. One hundred and ten (110 response-soliciting statements were subjected to discourse analytic procedure to determine the features of such utterances. The results showed that her interview procedure follows a certain pattern that contributes to her ability to maintain the intimacy, familiarity, and dynamics of conversation. Further, results revealed that the interviewer employs a variety of response-soliciting strategies and transitional strategies that unconsciously put the control and authority in the conversation to the interviewees. Finally, some pedagogical implications were also presented for classroom use. Keywords: discourse analysis, interviewing style, interview questions, written discourse

Verb-Noun Collocations in Written Discourse of Iranian EFL Learners

Directory of Open Access Journals (Sweden)

Fatemeh Ebrahimi-Bazzaz

2015-07-01

Full Text Available When native speakers of English write, they employ both grammatical rules and collocations. Collocations are words that are present in the memory of native speakers as ready-made prefabricated chunks. Non-native speakers who wish to acquire native-like fluency should give appropriate attention to collocations in writing in order not to produce sentences that native speakers may consider odd. The present study tries to explore the use of verb-noun collocations in written discourse of English as foreign language (EFL among Iranian EFL learners from one academic year to the next in Iran. To measure the use of verb-noun collocations in written discourse, there was a 60-minute task of writing story  based on a series of six pictures whereby for each picture, three verb-noun collocations were measured, and nouns were provided to limit the choice of collocations. The results of the statistical analysis of ANOVA for the research question indicated that there was a significant difference in the use of lexical verb-noun collocations in written discourse both between and within the four academic years. The results of a post hoc multiple comparison tests confirmed that the means are significantly different between the first year and the third and fourth years, between the second and the fourth, and between the third and the fourth academic year which indicate substantial development in verb-noun collocation proficiency.  The vital implication is that the learners could use verb-noun collocations in productive skill of writing.

Understanding Extraordinary Architectural Experiences through Content Analysis of Written Narratives

Directory of Open Access Journals (Sweden)

Brandon Richard Ro

2015-12-01

Full Text Available This study a identifies how people describe, characterize, and communicate in written form Extraordinary Architectural Experiences (EAE, and b expands the traditional qualitative approach to architectural phenomenology by demonstrating a quantitative method to analyze written narratives. Specifically, this study reports on the content analysis of 718 personal accounts of EAEs. Using a deductive, ‘theory-driven’ approach, these narratives were read, coded, and statistically analyzed to identify storyline structure, convincing power, and the relationship between subjective and objective experiential qualities used in the story-telling process. Statistical intercoder agreement tests were conducted to verify the reliability of the interpretations to approach the hard problem of “extraordinary aesthetics” in architecture empirically. The results of this study confirm the aesthetic nature of EAE narratives (and of told experiences by showing their higher dependence on external objective content (e.g., a building’s features and location rather than its internal subjective counterpart (e.g., emotions and sensations, which makes them more outwardly focused. The strong interrelationships and intercoder agreement between the thematic realms provide a unique aesthetic construct revealing EAE narratives as memorable, embodied, emotional events mapped by the externally focused content of place, social setting, time, and building features. A majority of EAE narratives were found to possess plot-structure along with significant relationships to objective-subjective content that further grounded their storylines. This study concludes that content analysis provides not only a valid method to understand written narratives about extraordinary architectural experiences quantitatively, but also a view as to how to map the unique nature of aesthetic phenomenology empirically.

Long-term contraction of pyroclastic flow deposits at Augustine Volcano using InSAR

Science.gov (United States)

McAlpin, D. B.; Meyer, F. J.; Lu, Z.; Beget, J. E.

2013-12-01

Augustine Island is a small, 8x11 km island in South Central Alaska's lower Cook Inlet. It is approximately 280 km southwest of Anchorage, and occupied entirely by its namesake Augustine Volcano. The volcano's nearly symmetrical central cone reaches an altitude of 1260 m, and the surrounding island is composed almost entirely of volcanic deposits. It is the youngest and most frequently active volcano in the lower Cook Inlet, with at least seven known eruptions since the beginning of written records in 1812. Its two most recent eruptions occurred during March-August 1986, and January-March 2006 The 1986 and 2006 Augustine eruptions produced significant pyroclastic flow deposits (PFDs) on the island, both which have been well mapped by previous studies. Subsidence of material deposited by these pyroclastic flows has been measured by InSAR data, and can be attributed to at least four processes: (1) initial, granular settling; (2) thermal contraction; (3) loading of 1986 PFDs from overlying 2006 deposits; and (4) continuing subsidence of 1986 PFDs buried beneath 2006 flows. For this paper, SAR data for PFDs from Augustine Volcano were obtained from 1992 through 2005, from 2006-2007, and from 2007-2011. These time frames provided InSAR data for long-term periods after both 1986 and 2006 eruptions. From time-series analysis of these datasets, deformation rates of 1986 PFDs and 2006 PFDs were determined, and corrections applied where newer deposits were emplaced over old deposits. The combination of data sets analyzed in this study enabled, for the first time, an analysis of long and short term subsidence rates of volcanic deposits emplaced by the two eruptive episodes. The generated deformation time series provides insight into the significance and duration of the initial settling period and allows us to study the thermal regime and heat loss of the PFDs. To extract quantitative information about thermal properties and composition of the PFDs, we measured the thickness

Justify Your Answer: The Role of Written Think Aloud in Script Concordance Testing.

Science.gov (United States)

Power, Alyssa; Lemay, Jean-Francois; Cooke, Suzette

2017-01-01

Construct: Clinical reasoning assessment is a growing area of interest in the medical education literature. Script concordance testing (SCT) evaluates clinical reasoning in conditions of uncertainty and has emerged as an innovative tool in the domain of clinical reasoning assessment. SCT quantifies the degree of concordance between a learner and an experienced clinician and attempts to capture the breadth of responses of expert clinicians, acknowledging the significant yet acceptable variation in practice under situations of uncertainty. SCT has been shown to be a valid and reliable clinical reasoning assessment tool. However, as SCT provides only quantitative information, it may not provide a complete assessment of clinical reasoning. Think aloud (TA) is a qualitative research tool used in clinical reasoning assessment in which learners verbalize their thought process around an assigned task. This study explores the use of TA, in the form of written reflection, in SCT to assess resident clinical reasoning, hypothesizing that the information obtained from the written TA would enrich the quantitative data obtained through SCT. Ninety-one pediatric postgraduate trainees and 21 pediatricians from 4 Canadian training centers completed an online test consisting of 24 SCT cases immediately followed by retrospective written TA. Six of 24 cases were selected to gather TA data. These cases were chosen to allow all phases of clinical decision making (diagnosis, investigation, and treatment) to be represented in the TA data. Inductive thematic analysis was employed when systematically reviewing TA responses. Three main benefits of adding written TA to SCT were identified: (a) uncovering instances of incorrect clinical reasoning despite a correct SCT response, (b) revealing sound clinical reasoning in the context of a suboptimal SCT response, and (c) detecting question misinterpretation. Written TA can optimize SCT by demonstrating when correct examinee responses are based on

Gran, Sarah Frandsen; Braend, Anja Maria; Lindbaek, Morten

2010-01-01

Many medical students in general practice clerkships experience lack of observation-based feedback. The StudentPEP project combined written feedback from patients, observing teachers and students. This study analyzes the perceived usefulness of triangulated written feedback. A total of 71 general practitioners and 79 medical students at the University of Oslo completed project evaluation forms after a 6-week clerkship. A principal component analysis was performed to find structures within the questionnaire. Regression analysis was performed regarding students' answers to whether StudentPEP was worthwhile. Free-text answers were analyzed qualitatively. Student and teacher responses were mixed within six subscales, with highest agreement on 'Teachers oral and written feedback' and 'Attitude to patient evaluation'. Fifty-four per cent of the students agreed that the triangulation gave concrete feedback on their weaknesses, and 59% valued the teachers' feedback provided. Two statements regarding the teacher's attitudes towards StudentPEP were significantly associated with the student's perception of worthwhileness. Qualitative analysis showed that patient evaluations were encouraging or distrusted. Some students thought that StudentPEP ensured observation and feedback. The patient evaluations increased the students' awareness of the patient perspective. A majority of the students considered the triangulated written feedback beneficial, although time-consuming. The teacher's attitudes strongly influenced how the students perceived the usefulness of StudentPEP.

Acid Deposition Phenomena

International Nuclear Information System (INIS)

Ramadan, A.E.K.

2004-01-01

Acid deposition, commonly known as acid rain, occurs when emissions from the combustion of fossil fuels and other industrial processes undergo complex chemical reactions in the atmosphere and fall to the earth as wet deposition (rain, snow, cloud, fog) or dry deposition (dry particles, gas). Rain and snow are already naturally acidic, but are only considered problematic when less than a ph of 5.0 The main chemical precursors leading to acidic conditions are atmospheric concentrations of sulfur dioxide (SO 2 ) and nitrogen oxides (NO x ). When these two compounds react with water, oxygen, and sunlight in the atmosphere, the result is sulfuric (H 2 SO 4 ) and nitric acids (HNO 3 ), the primary agents of acid deposition which mainly produced from the combustion of fossil fuel and from petroleum refinery. Airborne chemicals can travel long distances from their sources and can therefore affect ecosystems over broad regional scales and in locations far from the sources of emissions. According to the concern of petroleum ministry with the environment and occupational health, in this paper we will discussed the acid deposition phenomena through the following: Types of acidic deposition and its components in the atmosphere Natural and man-made sources of compounds causing the acidic deposition. Chemical reactions causing the acidic deposition phenomenon in the atmosphere. Factors affecting level of acidic deposition in the atmosphere. Impact of acid deposition. Procedures for acidic deposition control in petroleum industry

Full Text Available The objective of this study is to find out whether there is a significant difference in terms of writing skills improvements between the 8th grade students of SMP N 1 Prambanan Sleman who are given teacher’s written feedback and conference and those who are not in the academic year of 2011/2012. This study involved 71 students from two groups, Class VIII B (35 students as the experimental group and Class VIII A (36 students as the control group. The experimental group was given teacher’s written feedback and conference in the writing learning process, whereas the control group was given peer’s feedback. The data were obtained by using two essay writing tests. They were administered to the two groups as the pre-test and post-test. The pre-test was given to both groups before the treatment was given and the post-test was given after the treatment finished. The data of the pre-test and post-test of both groups were analyzed by means of descriptive and inferential statistics. After the data were tested and found to be homogeneous and normal, the hypothesis was tested using the analysis of covariance (ANCOVA. The results show that there is a significant difference in the writing ability between the students who are given teacher’s written feedback and conference and those who were not. It can be seen in the result of the hypothesis testing using ANCOVA. The significant value of 0.001 is less than the significance level of 0.05 (0.001 < 0.05, which means that the data of this study are considered to have a significant difference. Therefore, the hypothesis of this study is accepted. It means that the technique of giving teacher’s written feedback and conference significantly improves the students’ writing ability in the English teaching and learning process in SMP N 1 Prambanan Sleman.

Assessing readability formula differences with written health information materials: application, results, and recommendations.

Science.gov (United States)

Wang, Lih-Wern; Miller, Michael J; Schmitt, Michael R; Wen, Frances K

2013-01-01

Readability formulas are often used to guide the development and evaluation of literacy-sensitive written health information. However, readability formula results may vary considerably as a result of differences in software processing algorithms and how each formula is applied. These variations complicate interpretations of reading grade level estimates, particularly without a uniform guideline for applying and interpreting readability formulas. This research sought to (1) identify commonly used readability formulas reported in the health care literature, (2) demonstrate the use of the most commonly used readability formulas on written health information, (3) compare and contrast the differences when applying common readability formulas to identical selections of written health information, and (4) provide recommendations for choosing an appropriate readability formula for written health-related materials to optimize their use. A literature search was conducted to identify the most commonly used readability formulas in health care literature. Each of the identified formulas was subsequently applied to word samples from 15 unique examples of written health information about the topic of depression and its treatment. Readability estimates from common readability formulas were compared based on text sample size, selection, formatting, software type, and/or hand calculations. Recommendations for their use were provided. The Flesch-Kincaid formula was most commonly used (57.42%). Readability formulas demonstrated variability up to 5 reading grade levels on the same text. The Simple Measure of Gobbledygook (SMOG) readability formula performed most consistently. Depending on the text sample size, selection, formatting, software, and/or hand calculations, the individual readability formula estimated up to 6 reading grade levels of variability. The SMOG formula appears best suited for health care applications because of its consistency of results, higher level of expected

Clarity Versus Accuracy and Objectivity in Written Legal English

Directory of Open Access Journals (Sweden)

Violeta Janulevičienė

2011-12-01

Full Text Available This paper is an attempt to analyse the most important grammatical and, specifically, syntactic features and to point out some prominent lexical ones, which aim at accuracy and objectivity of a written legal document, and to discuss how these features influence clarity and transparency of the legal documents. The study covers the analysis of some EU, UK, US legislative acts alongside with some extracts from contract samples. The analysis reveals that written legal English is distinguished by long compound sentences, often with inverted word order and numerous embeddings, passive constructions and nominalisations, specific use of personal pronouns and collocations of synonyms (doublets and triplets, etc. These means allow to achieve the most possible accuracy and objectivity in legal texts but make them complicated and difficult to comprehend at once. Formality, achieved by the mentioned means, makes legal English distant from everyday language and often becomes a reason for criticism. Plain English supporters encourage simplifying legal language; however, long traditions of legal English make changes slow and difficult. Therefore, comprehension and usage of legal English still requires special knowledge of its lexical and grammatical features.

What Comes First, What Comes Next: Information Packaging in Written and Spoken Language

Directory of Open Access Journals (Sweden)

Vladislav Smolka

2017-07-01

Full Text Available The paper explores similarities and differences in the strategies of structuring information at sentence level in spoken and written language, respectively. In particular, it is concerned with the position of the rheme in the sentence in the two different modalities of language, and with the application and correlation of the end-focus and the end-weight principles. The assumption is that while there is a general tendency in both written and spoken language to place the focus in or close to the final position, owing to the limitations imposed by short-term memory capacity (and possibly by other factors, for the sake of easy processibility, it may occasionally be more felicitous in spoken language to place the rhematic element in the initial position or at least close to the beginning of the sentence. The paper aims to identify differences in the function of selected grammatical structures in written and spoken language, respectively, and to point out circumstances under which initial focus is a convenient alternative to the usual end-focus principle.

Examining Elementary Students' Development of Oral and Written Argumentation Practices Through Argument-Based Inquiry

Science.gov (United States)

Chen, Ying-Chih; Hand, Brian; Park, Soonhye

2016-05-01

Argumentation, and the production of scientific arguments are critical elements of inquiry that are necessary for helping students become scientifically literate through engaging them in constructing and critiquing ideas. This case study employed a mixed methods research design to examine the development in 5th grade students' practices of oral and written argumentation from one unit to another over 16 weeks utilizing the science writing heuristic approach. Data sources included five rounds of whole-class discussion focused on group presentations of arguments that occurred over eleven class periods; students' group writings; interviews with six target students and the teacher; and the researcher's field notes. The results revealed five salient trends in students' development of oral and written argumentative practices over time: (1) Students came to use more critique components as they participated in more rounds of whole-class discussion focused on group presentations of arguments; (2) by challenging each other's arguments, students came to focus on the coherence of the argument and the quality of evidence; (3) students came to use evidence to defend, support, and reject arguments; (4) the quality of students' writing continuously improved over time; and (5) students connected oral argument skills to written argument skills as they had opportunities to revise their writing after debating and developed awareness of the usefulness of critique from peers. Given the development in oral argumentative practices and the quality of written arguments over time, this study indicates that students' development of oral and written argumentative practices is positively related to each other. This study suggests that argumentative practices should be framed through both a social and epistemic understanding of argument-utilizing talk and writing as vehicles to create norms of these complex practices.

Attentive Reading With Constrained Summarization Adapted to Address Written Discourse in People With Mild Aphasia.

Science.gov (United States)

Obermeyer, Jessica A; Edmonds, Lisa A

2018-03-01

The purpose of this study was to examine the preliminary efficacy of Attentive Reading and Constrained Summarization-Written (ARCS-W) in people with mild aphasia. ARCS-W adapts an existing treatment, ARCS (Rogalski & Edmonds, 2008), to address discourse level writing in mild aphasia. ARCS-W focuses on the cognitive and linguistic skills required for discourse production. This study was a within-subject pre-postdesign. Three people with mild aphasia participated. ARCS-W integrates attentive reading or listening with constrained summarization of discourse level material in spoken and written modalities. Outcomes included macro- (main concepts) and microlinguistic (correct information units, complete utterances) discourse measures, confrontation naming, aphasia severity, and functional communication. All 3 participants demonstrated some generalization to untrained spoken and written discourse at the word, sentence, and text levels. Reduced aphasia severity and/or increased functional communication and confrontation naming were also observed in some participants. The findings of this study provide preliminary evidence of the efficacy of ARCS-W to improve spoken and written discourse in mild aphasia. Different generalization patterns suggest different mechanisms of improvement. Further research and replication are required to better understand how ARCS-W can impact discourse abilities.

Syllable frequency and word frequency effects in spoken and written word production in a non-alphabetic script

Directory of Open Access Journals (Sweden)

Qingfang eZhang

2014-02-01

Full Text Available The effects of word frequency and syllable frequency are well-established phenomena in domain such as spoken production in alphabetic languages. Chinese, as a non-alphabetic language, presents unique lexical and phonological properties in speech production. For example, the proximate unit of phonological encoding is syllable in Chinese but segments in Dutch, French or English. The present study investigated the effects of word frequency and syllable frequency, and their interaction in Chinese written and spoken production. Significant facilitatory word frequency and syllable frequency effects were observed in spoken as well as in written production. The syllable frequency effect in writing indicated that phonological properties (i.e., syllabic frequency constrain orthographic output via a lexical route, at least, in Chinese written production. However, the syllable frequency effect over repetitions was divergent in both modalities: it was significant in the former two repetitions in spoken whereas it was significant in the second repetition only in written. Due to the fragility of the syllable frequency effect in writing, we suggest that the phonological influence in handwritten production is not mandatory and universal, and it is modulated by experimental manipulations. This provides evidence for the orthographic autonomy hypothesis, rather than the phonological mediation hypothesis. The absence of an interaction between word frequency and syllable frequency showed that the syllable frequency effect is independent of the word frequency effect in spoken and written output modalities. The implications of these results on written production models are discussed.

Wendt, Christel

2017-12-01

This study aimed to investigate experiences of verbal and written information about sex and relationships among men and women treated with hematopoietic stem cell transplantation. The study also aimed to investigate the demand for information and assessment of the quality of written patient information material entitled "Sex and relationships in the treatment of blood diseases." Few studies exist that shed any light on the demand for information about sex and relationships on the part of patients with hematological diseases before, during, and after their treatment. A total of 216 patients undergoing treatment for malignant blood diseases between 2000 and 2010 participated in this study. Patients' experiences of information about sex and relationships, and their opinions about the written patient information, were assessed using a questionnaire created specifically for this study. Most patients (81 %) had not received information about sex and relationships from a healthcare professional. Almost 90 % of men felt that verbal information was important, compared with 82 % of women. The majority also held that written information was important. These results indicate that patients, regardless of gender, age, and treatment, consider oral and written information about sex and relationships to be important and that the healthcare system should provide the information. The written patient information was considered to play an important role in creating an opening for a conversation about a sensitive topic such as sexuality, and also as a source of reference and support for the patient and his/her partner.

Top-down influences of written text on perceived clarity of degraded speech.

Science.gov (United States)

Sohoglu, Ediz; Peelle, Jonathan E; Carlyon, Robert P; Davis, Matthew H

2014-02-01

An unresolved question is how the reported clarity of degraded speech is enhanced when listeners have prior knowledge of speech content. One account of this phenomenon proposes top-down modulation of early acoustic processing by higher-level linguistic knowledge. Alternative, strictly bottom-up accounts argue that acoustic information and higher-level knowledge are combined at a late decision stage without modulating early acoustic processing. Here we tested top-down and bottom-up accounts using written text to manipulate listeners' knowledge of speech content. The effect of written text on the reported clarity of noise-vocoded speech was most pronounced when text was presented before (rather than after) speech (Experiment 1). Fine-grained manipulation of the onset asynchrony between text and speech revealed that this effect declined when text was presented more than 120 ms after speech onset (Experiment 2). Finally, the influence of written text was found to arise from phonological (rather than lexical) correspondence between text and speech (Experiment 3). These results suggest that prior knowledge effects are time-limited by the duration of auditory echoic memory for degraded speech, consistent with top-down modulation of early acoustic processing by linguistic knowledge.

S. da Silva, Diego; Wetter, Niklaus U.; de Rossi, Wagner; Samad, Ricardo E.; Kassab, Luciana R. P.

2018-02-01

The authors report the fabrication and characterization of passive waveguides in GeO2-PbO and TeO2-ZnO glasses written with a femtosecond laser delivering pulses with 3μJ, 30μJ and 80fs at 4kHz repetition rate. Permanent refractive index change at the focus of the laser beam was obtained and waveguides were formed by two closely spaced laser written lines, where the light guiding occurs between them. The refractive index change at 632 nm is around 10-4 . The value of the propagation losses was around 2.0 dB/cm. The output mode profiles indicate multimodal guiding behavior. Raman measurements show structural modification of the glassy network. The results show that these materials are potential candidates for passive waveguides applications as low-loss optical components.

Walton, Jo Ann; Lindsay, Natalie; Hales, Caz; Rook, Helen

2018-01-01

This study was born out of our reflections as educators responsible for helping new graduate nurses transition into their first year of professional practice through a formal education programme. Finding ourselves wondering about many of the questions the students raised with us, we set about looking more closely at what could be gleaned from the students' experience, captured in their written work over the course of a year. To identify the challenges and learning experiences revealed in reflective assignments written by new graduate nurses undertaking a postgraduate course as part of their transition to registered nurse practice. Data consisted of the written work of two cohorts of students who had completed a postgraduate university course as part of their transition to new graduate practice in New Zealand. Fifty four reflective essays completed by twenty seven participating students were collected and their contents analysed thematically. Five key themes were identified. The students' reflections noted individual attributes - personal and professional strengths and weaknesses; professional behaviour - actions such as engaging help and support, advocating for patients' needs and safety and putting their own feelings aside; situational challenges such as communication difficulties, both systemic and interpersonal, and the pressure of competing demands. Students also identified rewards - results they experienced such as achieving the nursing outcomes they desired, and commented on reflection as a useful tool. The findings shed light on the experiences of new graduates, and how they fare through this critical phase of career development. Challenges relating to the emotional labour of nursing work are particularly evident. In addition the reflective essay is shown to be a powerful tool for assisting both new graduate nurses and their lecturers to reflect on the learning opportunities inherent in current clinical practice environments.

Deposition characteristics of titanium coating deposited on SiC fiber by cold-wall chemical vapor deposition

Energy Technology Data Exchange (ETDEWEB)

Luo, Xian, E-mail: luo_shenfan@hotmail.com; Wu, Shuai; Yang, Yan-qing; Jin, Na; Liu, Shuai; Huang, Bin

2016-12-01

The deposition characteristics of titanium coating on SiC fiber using TiCl{sub 4}-H{sub 2}-Ar gas mixture in a cold-wall chemical vapor deposition were studied by the combination of thermodynamic analysis and experimental studies. The thermodynamic analysis of the reactions in the TiCl{sub 4}-H{sub 2}-Ar system indicates that TiCl{sub 4} transforms to titanium as the following paths: TiCl{sub 4} → TiCl{sub 3} → Ti, or TiCl{sub 4} → TiCl{sub 3} → TiCl{sub 2} → Ti. The experimental results show that typical deposited coating contains two distinct layers: a TiC reaction layer close to SiC fiber and titanium coating which has an atomic percentage of titanium more than 70% and that of carbon lower than 30%. The results illustrate that a carbon diffusion barrier coating needs to be deposited if pure titanium is to be prepared. The deposition rate increases with the increase of temperature, but higher temperature has a negative effect on the surface uniformity of titanium coating. In addition, appropriate argon gas flow rate has a positive effect on smoothing the surface morphology of the coating. - Highlights: • Both thermodynamic analysis and experimental studies were adopted in this work. • The transformation paths of TiCl{sub 4} to Ti is: TiCl{sub 4} → TiCl{sub 3} → Ti, or TiCl{sub 4} → TiCl{sub 3} → TiCl{sub 2} → Ti. • Typical deposited Ti coating on SiC fiber contained two distinct layers. • Deposition temperature is important on deposition rate and morphologies. • Appropriate argon gas flow rate has a positive effect on smoothing of the coating.

Deposition of Boron in Possible Evaporite Deposits in Gale Crate

Boron has been previously detected in Gale crater using the ChemCam instrument on board the NASA Curiosity rover within calcium sulfate fracture fill hosted by lacustrine mudstone and eolian sandstone units. Recent results show that up to 300 ppm B is present in the upper sections of the lacustrine unit. Boron has been detected in both the groundwater-emplaced calcium sulfate fracture fill materials and bedding-parallel calcium sulfate layers. The widespread bedding-parallel calcium sulfate layers within the upper strata of the lacustrine bedrock that Curiosity has encountered recently could be interpreted as primary evaporite deposits. We have two hypotheses for the history of boron in Gale crater. In both hypotheses, borates were first deposited as lake water evaporated, depositing primary evaporates that were later re-dissolved by groundwater, which redistributed the boron into secondary evaporitic calcium sulfate fracture fill deposits. In the first scenario, Gale crater may have undergone a period of perennial lake formation during a drier period of martian history, depositing layers of evaporitic minerals (including borates) among lacustrine mudstone layers. In the second scenario, lake margins could have become periodically exposed during cyclic drops in lake level and subsequently desiccated. Evaporites were deposited and desiccation features were formed in lowstand deposits. Either hypothetical scenario of evaporite deposition would promote prebiotic chemical reactions via wet-dry cycles. Boron may be an important prebiotic element, and as such, its presence in ancient martian surface and groundwater provides evidence that important prebiotic chemical reactions could occur on Mars if organics were present. The presence of boron in ancient Gale crater groundwater also provides additional evidence that a habitable environment existed in the martian subsurface well after the expected disappearance of liquid water on the surface of Mars. We will report on the

Hedging to save face: a linguistic analysis of written comments on in-training evaluation reports.

Science.gov (United States)

Ginsburg, Shiphra; van der Vleuten, Cees; Eva, Kevin W; Lingard, Lorelei

2016-03-01

Written comments on residents' evaluations can be useful, yet the literature suggests that the language used by assessors is often vague and indirect. The branch of linguistics called pragmatics argues that much of our day to day language is not meant to be interpreted literally. Within pragmatics, the theory of 'politeness' suggests that non-literal language and other strategies are employed in order to 'save face'. We conducted a rigorous, in-depth analysis of a set of written in-training evaluation report (ITER) comments using Brown and Levinson's influential theory of 'politeness' to shed light on the phenomenon of vague language use in assessment. We coded text from 637 comment boxes from first year residents in internal medicine at one institution according to politeness theory. Non-literal language use was common and 'hedging', a key politeness strategy, was pervasive in comments about both high and low rated residents, suggesting that faculty may be working to 'save face' for themselves and their residents. Hedging and other politeness strategies are considered essential to smooth social functioning; their prevalence in our ITERs may reflect the difficult social context in which written assessments occur. This research raises questions regarding the 'optimal' construction of written comments by faculty.

Meeting the Demands of the Workplace: Science Students and Written Skills

Gray, F. Elizabeth; Emerson, Lisa; Mackay, Bruce

2005-12-01

Over the last 15 years, surveys in a range of English-speaking countries, from North America and the United Kingdom, to New Zealand and Australia, have consistently shown that employers rank oral and written communication skills as highly as or more highly than any technical or quantitative skills. However, in New Zealand there has been very little research into determining exactly what is meant by the "written communication skills" employers state they desire. A further issue in this research to date has been a lack of differentiation between employers—no study has specifically targeted the requirements of employers of science graduates. This article reports the findings of ongoing research into the expectations of science students and of employers of science graduates, and centers around several key questions: What do New Zealand employers of science graduates specifically want in terms of their new hires' writing skills?

SOCIOLINGUISTIC FACTORS OF THE WRITTEN SPEECH NORMS APPROXIMATION IN LABOR MIGRANTS’ TEXTS

Directory of Open Access Journals (Sweden)

Utesheva Altynay Pazylovna

2015-06-01

Full Text Available The article focuses on the features of written Russian speech of labor migrants from different countries considering the norms of written speech. The empirical basis of the research is represented by the handwritten CVs of unemployed migrants from Vietnam and Uzbekistan, that were presented to the departments of the Federal Migration Service of the Russian Federation in the city of Volgograd. Written speech violations are classified according to the age groups which migrants belong to. The following sociolinguistic characteristics of the migrants are also taken into account: nationality, period of school education, higher education, document writing competence. Group 1 combined informants aged from 20 to 30, without higher education, who studied the Russian language at school in the new period of the collapse of the Soviet Union procedures or on their own. It is an educational institution with no experience compiling official documents and communication skills in Russian. Group 2 combined informants aged from 30 to 50, without higher education, who studied Russian at school by Soviet methods with experience of drawing up official documents and possessing basic communication skills to communicate in Russian. Group 3 combined informants aged 50 and older with secondary special education, who studied Russian at school by Soviet methods and actively developed communicative competence at the expense of everyday communication, reading books, listening to the radio and watching programs in Russian, with experience in drafting official documents. The features of migrants' written speech are manifested in specific language and speech mistakes, particularly in graphic, phonetic and genre rules violations. The general patterns of mistakes are registered. The mistakes are caused not only by language transfer and the Russian language competence, but also by sociolinguistic factors. The particular cross-language differences of migrants writing are

Salomé, Franck; Boyer, Patrice; Fayol, Michel

2002-08-30

The aim of this study is to discover whether the language capabilities of young schizophrenic patients are more affected in speaking than in writing or whether the disorders are equivalent in the two modes. To do this, we compared spoken and written descriptions of pictures obtained from 10 schizophrenic patients with those produced by 10 control subjects. These productions were analysed on the basis of objective indices. The syntax and coherence of the productions were evaluated by judges. The comparison of the performances of the controls and schizophrenic patients supports the hypothesis that the latter suffer from a language disorder affecting the oral mode but impacting less frequently and less severely on the written mode. These results are discussed in the light of the cognitive mechanisms which may provide an explanation of these language disorders.

Pinto, Giuliana; Tarchi, Christian; Bigozzi, Lucia

2015-12-01

The relationship between oral language and the writing process at early acquisition stages and the ways the former can enhance or limit the latter has not been researched extensively. The predictive relationship between kindergarten oral narrative competence and the first- and second-grade written narrative competence was explored in a 3-year longitudinal study. Among the first and second graders, the relationship between orthographic competence and narrative competence in written productions was also analysed. One hundred and nine Italian children participated in this study. Kindergarteners produced an oral narrative, whereas the first and second graders produced a written narrative. The oral and written narratives were analysed in terms of cohesion, coherence, and structure. The first-grade orthographic competence was assessed via a dictation task. Multiple linear regression and mediational analyses were performed. Kindergarten oral narrative competence affected the first- and second-grade written narrative competence via a mediational effect of orthographic competence. The results suggest the importance of practicing oral narrative competence in kindergarten and first grade and the value of composition quality independent of orthographic text accuracy. © 2015 The British Psychological Society.

This work investigates the use of plasma-enhanced chemical vapor deposition under atmospheric pressure for achieving uniform layer formation. Electrical and optical measurements demonstrated that the counterbalance between oxygen and precursors maintained the homogeneous discharge mode, while creating intermediate species for layer deposition. Several steps of the deposition process of the layers, which were processed on a stationary stage, were affected by flow stream and precursor depletion. This study showed that by changing the flow streamlines using substrate stage motion uniform layer deposition under atmospheric pressure can be achieved. - Highlights: • Zirconium oxide was deposited by atmospheric-pressure plasma-enhanced chemical vapor deposition. • Homogeneous plasma was maintained by counterbalancing between discharge gas and precursors. • Several deposition steps were observed affected by the gas flow stream and precursor depletion. • Thin film layer was uniformly grown when the substrate underwent a sweeping motion.

Text Comprehension Mediates Morphological Awareness, Syntactic Processing, and Working Memory in Predicting Chinese Written Composition Performance

Science.gov (United States)

Guan, Connie Qun; Ye, Feifei; Wagner, Richard K.; Meng, Wanjin; Leong, Che Kan

2014-01-01

The goal of the present study was to test opposing views about four issues concerning predictors of individual differences in Chinese written composition: (a) Whether morphological awareness, syntactic processing, and working memory represent distinct and measureable constructs in Chinese or are just manifestations of general language ability; (b) whether they are important predictors of Chinese written composition, and if so, the relative magnitudes and independence of their predictive relations; (c) whether observed predictive relations are mediated by text comprehension; and (d) whether these relations vary or are developmentally invariant across three years of writing development. Based on analyses of the performance of students in grades 4 (n = 246), 5 (n = 242) and 6 (n = 261), the results supported morphological awareness, syntactic processing, and working memory as distinct yet correlated abilities that made independent contributions to predicting Chinese written composition, with working memory as the strongest predictor. However, predictive relations were mediated by text comprehension. The final model accounted for approximately 75 percent of the variance in Chinese written composition. The results were largely developmentally invariant across the three grades from which participants were drawn. PMID:25530630

Rhetorical Use of Inscriptions in Students' Written Arguments About Socioscientific Issues

Xiao, Sihan

2018-05-01

Educators expect that students be able to make informed decisions about science-related problems in their everyday lives. Engaging science in such problems often entails evaluating available evidence for given arguments. This study explores how students use inscriptions as evidence to argue about socioscientific issues. Fifth- and sixth-grade students (N = 102) in two intact classrooms completed written argument tasks in which they were asked to cite given inscriptions to support their decisions about energy use or genetically modified organisms. Qualitative content analyses of these written arguments, which focused on the coordination between inscriptions and claims, show three patterns of rhetorical use of inscriptions: seeing is believing, believing is seeing, and asserting is inferring. What counts as evidence was not the inscriptions per se, but the rhetorical functions they performed in particular arguments. These findings suggest that justifying socioscientific decisions is functionally different from explaining scientific phenomena. Linking these two activities in school may help students more productively engage with science in their everyday lives.

We report an experimental study on the synthesis and characterization of zinc sulfide (ZnS) single layer thin films deposited on glass substrates by chemical bath deposition technique in acidic solution. The effect of deposition time on the microstructure, surface morphology, optical absorption, transmittance, and photoluminescence (PL) was investigated by X-ray diffraction (XRD), scanning electronic microscopy (SEM), UV-Vis–NIR spectrophotometry and photoluminescence (PL) spectroscopy. The results showed that the samples exhibit wurtzite structure and their crystal quality is improved by increasing deposition time. The latter, was found to affect the morphology of the thin films as showed by SEM micrographs. The optical measurements revealed a high transparency in the visible range and a dependence of absorption edge and band gap on deposition time. The room temperature PL spectra indicated that all ZnS grown thin films emit a UV and blue light, while the band intensities are found to be dependent on deposition times. - Highlights: • Single layer ZnS thin films were deposited by CBD in acidic solution at 95 °C. • The effect of deposition time was investigated. • Coexistence of ZnS and ZnO hexagonal structures for time deposition below 2 h • Thicker ZnS films were achieved after monolayer deposition for 5 h. • The highest UV-blue emission observed in thin film deposited at 5 h.

As a result of the discovery of uranium in surficial deposits of Tertiary to Recent age, in Australia and Southern Africa, increasing attention is being paid to the location and understanding of the genesis of these deposits. The paper discusses the definitions and terminology currently in use and a classification of these deposits is presented. It is concluded that in order to obtain a measure of clarity, the terms calcrete, gypcrete and dolocrete should not be used to describe the uraniferous valley-fill deposits of Southern Africa and Australia [af

Sandstone-type uranium deposits

International Nuclear Information System (INIS)

Austin, S.R.; D'Andrea, R.F. Jr.

1978-01-01

Three overall factors are necessary for formation of uranium deposits in sandstone: a source of uranium, host rocks capable of transmitting uranium-bearing solutions, and a precipitant. Possible sources of uranium in sandstone-type deposits include groundwaters emanating from granitic highlands, arkosic sediments, tuffaceous material within or overlying the host rocks, connate fluids, and overlying black shales. The first three sources are considered the most likely. Host rocks are generally immature sandstones deposited in alluvial-fan, intermontane-basin or marginal-marine environments, but uranium deposits do occur in well-winnowed barrier-bar or eolian sands. Host rocks for uranium deposits generally show coefficients of permeability on the order of 1 to 100 gal/day/ft 2 . Precipitants are normally agents capable of reducing uranium from the uranyl to the uranous state. The association of uranium with organic matter is unequivocal; H 2 S, a powerful reductant, may have been present at the time of formation of some deposits but may go unnoticed today. Vanadium can serve to preserve the tabular characteristics of some deposits in the near-surface environment, but is considered an unlikely primary precipitant for uranium. Uranium deposits in sandstone are divided into two overall types: peneconcordant deposits, which occur in locally reducing environments in otherwise oxidized sandstones; and roll-type deposits, which occur at the margin of an area where an oxidized groundwater has permeated an otherwise reduced sandstone. Uranium deposits are further broken down into four subclasses; these are described

Cultural-historical and cognitive approaches to understanding the origins of development of written speech

Directory of Open Access Journals (Sweden)

L.F. Obukhova

2014-08-01

Full Text Available We present an analysis of the emergence and development of written speech, its relationship to the oral speech, connections to the symbolic and modeling activities of preschool children – playing and drawing. While a child's drawing is traditionally interpreted in psychology either as a measure of intellectual development, or as a projective technique, or as a criterion for creative giftedness of the child, in this article, the artistic activity is analyzed as a prerequisite for development of written speech. The article substantiates the hypothesis that the mastery of “picture writing” – the ability to display the verbal content in a schematic picturesque plan – is connected to the success of writing speech at school age. Along with the classical works of L.S. Vygotsky, D.B. Elkonin, A.R. Luria, dedicated to finding the origins of writing, the article presents the current Russian and foreign frameworks of forming the preconditions of writing, based on the concepts of cultural-historical theory (“higher mental functions”, “zone of proximal development”, etc.. In Western psychology, a number of pilot studies used the developmental function of drawing for teaching the written skills to children of 5-7 years old. However, in cognitive psychology, relationship between drawing and writing is most often reduced mainly to the analysis of general motor circuits. Despite the recovery in research on writing and its origins in the last decade, either in domestic or in foreign psychology, the written speech is not a sufficiently studied problem.

Polymer deposition morphology by electrospray deposition - Modifications through distance variation

International Nuclear Information System (INIS)

Altmann, K.; Schulze, R.-D.; Friedrich, J.

2014-01-01

Electrospray deposition (ESD) of highly diluted polymers was examined with regard to the deposited surface structure. Only the flight distance (flight time) onto the resulting deposited surface was varied from 20 to 200 mm. An apparatus without any additional heating or gas flows was used. Polyacrylic acid (PAA) and polyallylamine (PAAm) in methanol were deposited on Si wafers. The polymer layers were characterized by scanning electron microscopy, X-ray photoelectron spectroscopy, derivatization reactions and Fourier transform infrared spectroscopy using a grazing incidence unit. SEM images illustrated the changing structures of PAA and PAAm. For PAA the deposited structure changed from a smooth film (20 mm) to a film with individual droplets on the coated surface (100 mm and 200 mm), while for PAAm individual droplets can be seen at all distances. The ESD process with cascades of splitting droplets slows down for PAA after distances greater than 40 mm. In contrast, the ESD process for PAAm is nearly stopped within the first flight distance of 20 mm. Residual solvent analysis showed that most of the solvent evaporated within the first 20 mm capillary-sample distance. - Highlights: • We deposited polyacrylic acid and polyallylamine by electrospray ionization (ESI). • The morphology in dependence of flight distance (20 mm to 200 mm) was analyzed. • The amount of residual solvent after deposition was determined. • ESI-process slows down for polyacrylic acid after 40 mm flight distance. • ESI-Process is complete for polyallylamine within the first 20 mm

2018-01-01

Individuals with type 2 diabetes mellitus (T2DM) are responsible for the daily decisions and actions necessary to manage their disease, which makes self-management the cornerstone of diabetes care. Many patients do not reach recommended treatment goals, and thus it is important to develop and evaluate innovative interventions that facilitate optimal motivation for adequate self-management of T2DM. The aim of the current study was to explore how adults with T2DM experience using reflection sheets to stimulate written reflection in the context of the Guided Self-Determination (GSD) eHealth intervention and how written reflection might affect their motivation for self-management of T2DM. We used a qualitative design in which data were collected through individual interviews. The sample consisted of 10 patients who completed the GSD eHealth intervention, and data were analyzed using qualitative content analysis. The qualitative content analysis yielded 2 main themes. We labeled the first theme as "Written reflection affects awareness and commitment in diabetes self-management", which reflects 2 subthemes, namely, "Writing creates space and time for autonomous reflection" and "Writing influences individuals' focus in diabetes self-management". We labeled the second theme as "Written reflection is perceived as inapplicable in diabetes self-management", which reflects 2 subthemes, namely, "Responding in writing is difficult" and "The timing of the writing is inappropriate". Our findings indicate that written reflection in the context of the GSD eHealth intervention may be conducive to motivation for diabetes self-management for some patients. However, it seems that in-person consultation with the diabetes nurse may be necessary to achieve the full potential benefit of the GSD as an eHealth intervention. We advocate further development and examination of the GSD as a "blended" approach, especially for those who consider written reflection to be difficult or unfamiliar.

Regional programmes in Sweden focused on deposition and effects of air pollutants have been evaluated by IVL, Swedish Environmental Research Institute. Various air quality protection associations and regional environmental authorities initiated the monitoring programmes during the period 1985 to 1990. The result of the evaluation is a revised and coordinated programme with improved methods. The new regional programme combines collection of field data with national model calculations of deposition of air pollutants. The new programme involves collection of deposition on open field (bulk) and in forest stands (throughfall), and soil solution, according to national and international standards. Improved methods for monitoring of base cation and nitrogen deposition have been developed. Ambient air concentrations are measured at some locations. The purpose is to describe environmental conditions, regional differences, and temporal changes. Data on forest stands, such as needle loss, growth, and soil chemistry, are available since most locations are permanent forest plots, established for scientific forest observations. Regional dispersion and deposition of air pollutants will be calculated with a model (SMHI-MATCH), developed for simulating the dispersion and deposition of Swedish emissions in relation to the long-range transport on a relatively fine scale (grid square 11 km). The programme also includes developed methods for data handling, interpretation, evaluation, quality assurance and demonstration of results in written reports and via Internet.

How deposition parameters control growth dynamics of nc-Si deposited by hot-wire chemical vapor deposition

Moutinho, H.R.; To, B.; Jiang, C.-S.; Xu, Y.; Nelson, B.P.; Teplin, C.W.; Jones, K.M.; Perkins, J.; Al-Jassim, M.M.

2006-01-01

We studied the growth of silicon films deposited by hot-wire chemical vapor deposition under different values of filament current, substrate temperature, and hydrogen dilution ratio. The physical and electrical properties of the films were studied by Raman spectroscopy, x-ray diffraction, atomic force microscopy, conductive-atomic force microscopy, and transmission electron microscopy. There is an interdependence of the growth parameters, and films grown with different parameters can have similar structures. We discuss why this interdependence occurs and how it influences the properties of the deposited films, as well as the deposition rate. In general, the films have a complex structure, with a mixture of amorphous (220)-oriented crystalline and nanocrystalline phases present in most cases. The amount of each phase can be controlled by the variation of one or more of the growth parameters at a time

Is handwriting constrained by phonology? Evidence from Stroop tasks with written responses and Chinese characters

Directory of Open Access Journals (Sweden)

Markus eDamian

2013-10-01

Full Text Available To what extent is handwritten word production based on phonological codes? A few studies conducted in Western languages have recently provided evidence showing that phonology contributes to the retrieval of graphemic properties in written output tasks. Less is known about how orthographic production works in languages with non-alphabetic scripts such as written Chinese. We report a Stroop study in which Chinese participants wrote the colour of characters on a digital graphic tablet; characters were either neutral, or homophonic to the target (congruent, or homophonic to an alternative (incongruent. Facilitation was found from congruent homophonic distractors, but only when the homophone shared the same tone with the target. This finding suggests a contribution of phonology to written word production. A second experiment served as a control experiment to exclude the possibility that the effect in Experiment 1 had an exclusively semantic locus. Overall, the findings offer new insight into the relative contribution of phonology to handwriting, particularly in non-Western languages.

Font size matters--emotion and attention in cortical responses to written words.

Bayer, Mareike; Sommer, Werner; Schacht, Annekathrin

2012-01-01

For emotional pictures with fear-, disgust-, or sex-related contents, stimulus size has been shown to increase emotion effects in attention-related event-related potentials (ERPs), presumably reflecting the enhanced biological impact of larger emotion-inducing pictures. If this is true, size should not enhance emotion effects for written words with symbolic and acquired meaning. Here, we investigated ERP effects of font size for emotional and neutral words. While P1 and N1 amplitudes were not affected by emotion, the early posterior negativity started earlier and lasted longer for large relative to small words. These results suggest that emotion-driven facilitation of attention is not necessarily based on biological relevance, but might generalize to stimuli with arbitrary perceptual features. This finding points to the high relevance of written language in today's society as an important source of emotional meaning.

The matrix-assisted pulsed laser evaporation (MAPLE) has been recently exploited for depositing films of nanomaterials by combining the advantages of colloidal inorganic nanoparticles and laser-based techniques. MAPLE-deposition of nanomaterials meeting applicative purposes demands their peculiar properties to be taken into account while planning depositions to guarantee a congruent transfer (in terms of crystal structure and geometric features) and explain the deposition outcome. In particular, since nanofluids can enhance thermal conductivity with respect to conventional fluids, laser-induced heating can induce different ablation thermal regimes as compared to the MAPLE-treatment of soft materials. Moreover, nanoparticles exhibit lower melting temperatures and can experience pre-melting phenomena as compared to their bulk counterparts, which could easily induce shape and or crystal phase modification of the material to be deposited even at very low fluences. In this complex scenario, this review paper focuses on examples of MAPLE-depositions of size and shape controlled nanoparticles for different applications highlights advantages and challenges of the MAPLE-technique. The influence of the deposition parameters on the physical mechanisms which govern the deposition process is discussed.

2007-01-01

Indium tin oxide thin films were deposited by computer assisted advanced PLD method in order to obtain transparent, conductive and homogeneous films on a large area. The films were deposited on glass substrates. We studied the influence of the temperature (room temperature (RT)-180 deg. C), pressure (1-6 x 10 -2 Torr), laser fluence (1-4 J/cm 2 ) and wavelength (266-355 nm) on the film properties. The deposition rate, roughness, film structure, optical transmission, electrical conductivity measurements were done. We deposited uniform ITO thin films (thickness 100-600 nm, roughness 5-10 nm) between RT and 180 deg. C on a large area (5 x 5 cm 2 ). The films have electrical resistivity of 8 x 10 -4 Ω cm at RT, 5 x 10 -4 Ω cm at 180 deg. C and an optical transmission in the visible range, around 89%

Spoken bilingualism may be associated with cognitive reserve. Mastering a complicated written language may be associated with additional reserve. We sought to determine if midlife use of spoken and written Japanese was associated with lower rates of late life cognitive decline. Participants were second-generation Japanese-American men from the Hawaiian island of Oahu, born 1900-1919, free of dementia in 1991, and categorized based on midlife self-reported use of spoken and written Japanese (total n included in primary analysis = 2,520). Cognitive functioning was measured with the Cognitive Abilities Screening Instrument scored using item response theory. We used mixed effects models, controlling for age, income, education, smoking status, apolipoprotein E e4 alleles, and number of study visits. Rates of cognitive decline were not related to use of spoken or written Japanese. This finding was consistent across numerous sensitivity analyses. We did not find evidence to support the hypothesis that multilingualism is associated with cognitive reserve.

Impurities in chromium deposits produced by electroplating and physical vapor deposition

Energy Technology Data Exchange (ETDEWEB)

Dini, J.W.

1994-05-01

Impurity contents in electrodeposited (hexavalent and trivalent) chromium deposits and physically vapor deposited (thermal evaporation, electron beam evaporation and rf-sputtering) were compared. Oxygen is the key impurity obtained in electrodeposited films but it can be minimized in hexavalent plating solutions by operating at high temperature, e. g., 85 C. Electrodeposits produced in trivalent chromium plating solutions and physically vapor deposited films have much higher oxygen contents than electrodeposits produced in hexavalent chromium solutions operated at temperatures around 85 C. Depending on the target material used for physically vapor deposited films, these films can also have high amounts of other impurities.

Two quartz microbalances have been used to record deposition on the National Spherical Torus Experiment. The experimental configuration mimics a typical diagnostic window or mirror. An RS232 link was used to acquire the quartz crystal frequency and the deposited thickness was recorded continuously with 0.01 nm resolution. Nuclear Reaction Analysis of the deposit was consistent with the measurement of the total deposited mass from the change in crystal frequency. We will present measurements of the variation of deposition with plasma conditions. The transport of carbon impurities in NSTX has been modelled with the BBQ code. Preliminary calculations indicated a negligible fraction of carbon generated at the divertor plates in quiescent discharges directly reaches the outer wall, and that transient events are responsible for the deposition.

Tur-Kaspa, Hana; Dromi, Esther

2001-04-01

The present study reports a detailed analysis of written and spoken language samples of Hebrew-speaking children aged 11-13 years who are deaf. It focuses on the description of various grammatical deviations in the two modalities. Participants were 13 students with hearing impairments (HI) attending special classrooms integrated into two elementary schools in Tel Aviv, Israel, and 9 students with normal hearing (NH) in regular classes in these same schools. Spoken and written language samples were collected from all participants using the same five preplanned elicitation probes. Students with HI were found to display significantly more grammatical deviations than their NH peers in both their spoken and written language samples. Most importantly, between-modality differences were noted. The participants with HI exhibited significantly more grammatical deviations in their written language samples than in their spoken samples. However, the distribution of grammatical deviations across categories was similar in the two modalities. The most common grammatical deviations in order of their frequency were failure to supply obligatory morphological markers, failure to mark grammatical agreement, and the omission of a major syntactic constituent in a sentence. Word order violations were rarely recorded in the Hebrew samples. Performance differences in the two modalities encourage clinicians and teachers to facilitate target linguistic forms in diverse communication contexts. Furthermore, the identification of linguistic targets for intervention must be based on the unique grammatical structure of the target language.

The aim of this study was to show how to verify plagiarism of the paper written in Macedonian and translated in foreign language. Original article "Ethics in Medical Research Involving Human Subjects", written in Macedonian, was submitted as an assay-2 for the subject Ethics and published by Ilina Stefanovska, PhD candidate from the Iustinianus Primus Faculty of Law, Ss Cyril and Methodius University of Skopje (UKIM), Skopje, Republic of Macedonia in Fabruary, 2013. Suspected article for plagiarism was published by Prof. Dr. Gordana Panova from the Faculty of Medical Sciences, University Goce Delchev, Shtip, Republic of Macedonia in English with the identical title and identical content in International scientific on-line journal "SCIENCE & TECHNOLOGIES", Publisher "Union of Scientists - Stara Zagora". Original document (written in Macedonian) was translated with Google Translator; suspected article (published in English pdf file) was converted into Word document, and compared both documents with several programs for plagiarism detection. It was found that both documents are identical in 71%, 78% and 82%, respectively, depending on the computer program used for plagiarism detection. It was obvious that original paper was entirely plagiarised by Prof. Dr. Gordana Panova, including six references from the original paper. Plagiarism of the original papers written in Macedonian and translated in other languages can be verified after computerised translation in other languages. Later on, original and translated documents can be compared with available software for plagiarism detection.

Urban wet deposition nitrate: a comparison to non-urban deposition

International Nuclear Information System (INIS)

Schultz, J.A.M.

1994-01-01

The concentration of nitrate in both wet and dry deposition has both increased historically and currently, and recently parallels emissions in NO x . Since NO x is produced in amounts comparable to SO 2 , it is an important contributor to acid deposition, and is produced in higher amounts in urban areas due to concentrated sources. Prior to to this study, national acid deposition monitoring networks in the United States have been and remain established in non-urban areas. This research study consisted of a comparison of precipitation sampling and analysis of wet deposition nitrate and pH for each deposition event in each of two urban sites over a 15 mo period. Also, a comparison of urban data and data generated at a nearby non-urban NADP site was made by examination of both monthly and seasonal data. This research suggests that national monitoring programs should consider inclusion of urban and non-urban monitoring sites in order to achieve a more representative regional assessment. 24 refs., 2 figs., 2 tabs

This report presents measurements and calculations from the atmospheric part of NOVA 2003 and covers results for 2000. It summarises the main results concerning concentrations and depositions of nitrogen, phosphorus and sulphur compounds related to eutrophication and acidification. Depositions of atmospheric compounds to Danish marine waters as well as land surface are presented. Measurements: In 2000 the monitoring program consisted of eight stations where wet deposition of ammonium, nitrate, phosphate (semi quantitatively) and sulphate were measured using bulk precipitation samplers. Six of the stations had in addition measurements of atmospheric content of A, nitrogen, phosphorus, and sulphur compounds in gas and particulate phase carried out by use of filter pack samplers. Filters were analysed at the National Environmental Research Institute. Furthermore nitrogen dioxide were measured using nitrogen dioxide filter samplers and monitors. Model calculations: The measurements in the monitoring program were supplemented with model calculations of concentrations and depositions of nitrogen and sulphur compounds to Danish land surface, marine waters, fjords and bays using the ACDEP model (Atmospheric Chemistry and Deposition). The model is a so-called trajectory model and simulates the physical and chemical processes in the atmosphere using meteorological and emission data as input. The advantage of combining measurements with model calculations is that the strengths of both methods is obtained. Conclusions concerning: 1) actual concentration levels at the monitoring stations, 2) deposition at the monitoring stations, 3) seasonal variations and 4) long term trends in concentrations and depositions are mainly based on the direct measurements. These are furthermore used to validate the results of the model calculations. Calculations and conclusions concerning: 1) depositions to land surface and to the individual marine water, 2) contributions from different emission

Occupational therapists working with school-aged children are often in the position of recommending technology to enhance written productivity. The outcome of using technology on the writing of children with learning disabilities has not been reviewed critically, and this knowledge is necessary for evidence-based practice. To review evidence regarding the use of technology to support written productivity in children with learning disabilities. A systematic search of seven databases, plus a manual search, retrieved 864 papers published between 1985 and March 2012. Twenty-seven papers (28 studies) met inclusion criteria. The evidence is of a moderately low level and results are inconclusive; however, trends suggest a positive influence of some technology on children's performance and behaviour. Methodological limitations exist in most studies and the description of specific technology intervention is often combined with teaching instructions. The available research is encouraging, but high-quality investigations with newer technologies are needed.

This paper describes the mutual impact of Analytical Chemistry and several international written standards (norms and guides) related to knowledge management (CEN-CWA 14924:2004), social responsibility (ISO 26000:2010), management of occupational health and safety (OHSAS 18001/2), environmental management (ISO 14001:2004), quality management systems (ISO 9001:2008) and requirements of the competence of testing and calibration laboratories (ISO 17025:2004). The intensity of this impact, based on a two-way influence, is quite different depending on the standard considered. In any case, a new and fruitful approach to Analytical Chemistry based on these relationships can be derived. Copyright © 2013 Elsevier B.V. All rights reserved.

[Written and pictorial content in magazines and their possible relationship to eating disorders].

Szabó, Kornélia; Túry, Ferenc

2012-02-01

In the current study we reviewed the literature on studies exploring the magazine reading frequency, written and pictorial contents appearing in magazines and their connection to eating disorders. Reading different fashion and fitness magazines has effect on readers through several indirect and direct factors and through trustable and false information. They affect readers' body satisfaction, self-esteem, eating habits and more generally their health behavior. Different theories have been explained to account for these associations and several other studies examined empirically the connection between the frequency of magazine reading and eating disorders, as well as the symptoms leading to eating disorders. We analyzed and summarized articles between 1975 and 2009 from online databases. We used the following sources: Science Direct (http://www.sciencedirect.com/), Springer-Verlag GmbH (http://www.springerlink.com/) and SAGE Publications Ltd (http://online.sagepub. com/). The pictorial and written magazine contents were associated with the development and maintenance of eating disorders or with symptoms that might lead to eating disorders. The publications compared to previous years featured an increased number of advertisements for unhealthy foods, for unhealthy radical diet plans and exercise programs. Furthermore the magazines contained conflicting messages about nutrition, body functions and eating disorders. Written and pictorial magazine contents, messages might increase the risk for development of eating disorders, especially in vulnerable individuals.

This study focuses on the mechanical characteristics of layered tool steel deposited using direct energy deposition (DED) technology. In the DED technique, a laser beam bonds injected metal powder and a thin layer of substrate via melting. In this study, AISI D2 substrate was hardfaced with AISI H13 and M2 metal powders for mechanical testing. The mechanical and metallurgical characteristics of each specimen were investigated via microstructure observation and hardness, wear, and impact tests. The obtained characteristics were compared with those of heat-treated tool steel. The microstructures of the H13- and M2-deposited specimens show fine cellular-dendrite solidification structures due to melting and subsequent rapid cooling. Moreover, the cellular grains of the deposited M2 layer were smaller than those of the H13 structure. The hardness and wear resistance were most improved in the M2-deposited specimen, yet the H13-deposited specimen had higher fracture toughness than the M2-deposited specimen and heat-treated D2.

Fundaments for the study of orality in written language

Directory of Open Access Journals (Sweden)

José Gaston Hilgert

2015-02-01

Full Text Available In this paper, we put forth some reflections upon the production of effects of orality in written texts in light of the fundaments of enunciation. In this theoretical context, we show that the study of orality in written language should not depart from the random identification of lexical and syntactic, figurative and thematic, stylistic or rhetoric resources. What matters is the identification of the interactive scenario in which these linguistic resources are manifested. The interactive scenario is configured by the relationship between narrator/narratee revealed in the text. If this relation takes place by means of the interaction between an I (narrator and a you (narratee, either explicit or implicit, then it is instituted, in this scenario, the basic principle of dialog, of conversation, which defines the proximity condition of the interlocutors and, therefore, the interactive scenario favorable to the use of orality resources. When this relation, however, takes place in the form of a third person narrator who addresses him/herself to an implicit reader, the scenario of distancing is installed, in which orality resources may be unfit or, if they occur, they may have specific functions. This text addresses special attention to the interactive scenario set by the interaction between I/you, showing, in different examples, traits of orality determined by such interaction, and also the various degrees of proximity that this interaction may reveal in its various manifestations.

Uses of the word "macula" in written English, 1400-present.

Schwartz, Stephen G; Leffler, Christopher T

2014-01-01

We compiled uses of the word "macula" in written English by searching multiple databases, including the Early English Books Online Text Creation Partnership, America's Historical Newspapers, the Gale Cengage Collections, and others. "Macula" has been used: as a non-medical "spot" or "stain", literal or figurative, including in astronomy and in Shakespeare; as a medical skin lesion, occasionally with a following descriptive adjective, such as a color (macula alba); as a corneal lesion, including the earliest identified use in English, circa 1400; and to describe the center of the retina. Francesco Buzzi described a yellow color in the posterior pole ("retina tinta di un color giallo") in 1782, but did not use the word "macula". "Macula lutea" was published by Samuel Thomas von Sömmering by 1799, and subsequently used in 1818 by James Wardrop, which appears to be the first known use in English. The Google n-gram database shows a marked increase in the frequencies of both "macula" and "macula lutea" following the introduction of the ophthalmoscope in 1850. "Macula" has been used in multiple contexts in written English. Modern databases provide powerful tools to explore historical uses of this word, which may be underappreciated by contemporary ophthalmologists. Copyright © 2014 Elsevier Inc. All rights reserved.

[A workshop to improve written communication skills of medical students].

Bitran, Marcela; Zúñiga, Denisse; Flotts, Paulina; Padilla, Oslando; Moreno, Rodrigo

2009-05-01

Despite being among the best academically prepared of the country, many medical students have difficulties to communicate in writing. In 2005, the School of Medicine at the Pontificia Universidad Católica de Chile introduced a writing workshop in the undergraduate curriculum, to enhance the students' writing skills. To describe the workshop and its impact on the writing skills of 3 cohorts of students. This 30-h workshop used a participative methodology with emphasis on deliberate practice and feedback. Students worked in small groups with a faculty member specially trained in writing. The qualities of the essays written before and after the workshop were compared. Essays were rated by a professional team that used an analytic rubric to measure formal aspects of text writing as well as more complex thinking processes. There was a significant improvement in the quality of the texts written after the workshop; the main changes occurred in argumentation, and in paragraph and text structure. This improvement was inversely proportional to the initial level of performance, and independent of gender. A writing workshop based on deliberate practice and personalized feedback is effective to enhance the writing proficiency of medical students. Due to its design, this workshop could be useful for students of other careers and universities.

Network analysis of named entity co-occurrences in written texts

Science.gov (United States)

Amancio, Diego Raphael

2016-06-01

The use of methods borrowed from statistics and physics to analyze written texts has allowed the discovery of unprecedent patterns of human behavior and cognition by establishing links between models features and language structure. While current models have been useful to unveil patterns via analysis of syntactical and semantical networks, only a few works have probed the relevance of investigating the structure arising from the relationship between relevant entities such as characters, locations and organizations. In this study, we represent entities appearing in the same context as a co-occurrence network, where links are established according to a null model based on random, shuffled texts. Computational simulations performed in novels revealed that the proposed model displays interesting topological features, such as the small world feature, characterized by high values of clustering coefficient. The effectiveness of our model was verified in a practical pattern recognition task in real networks. When compared with traditional word adjacency networks, our model displayed optimized results in identifying unknown references in texts. Because the proposed representation plays a complementary role in characterizing unstructured documents via topological analysis of named entities, we believe that it could be useful to improve the characterization of written texts (and related systems), specially if combined with traditional approaches based on statistical and deeper paradigms.

Many patients do not reach recommended treatment goals, and thus it is important to develop and evaluate innovative interventions that facilitate optimal motivation for adequate self-management of T2DM. Objective: The aim of the current study was to explore how adults with T2DM experience using reflection sheets to stimulate written reflection in the context of the Guided Self-Determination (GSD eHealth intervention and how written reflection might affect their motivation for self-management of T2DM. Methods: We used a qualitative design in which data were collected through individual interviews. The sample consisted of 10 patients who completed the GSD eHealth intervention, and data were analyzed using qualitative content analysis. Results: The qualitative content analysis yielded 2 main themes. We labeled the first theme as “Written reflection affects awareness and commitment in diabetes self-management”, which reflects 2 subthemes, namely, “Writing creates space and time for autonomous reflection” and “Writing influences individuals’ focus in diabetes self-management”. We labeled the second theme as “Written reflection is perceived as inapplicable in diabetes self-management”, which reflects 2 subthemes, namely, “Responding in writing is difficult” and “The timing of the writing is inappropriate”. Conclusion: Our findings

Direct writing of gold nanostructures with an electron beam: On the way to pure nanostructures by combining optimized deposition with oxygen-plasma treatment

Directory of Open Access Journals (Sweden)

Domagoj Belić

2017-11-01

Full Text Available This work presents a highly effective approach for the chemical purification of directly written 2D and 3D gold nanostructures suitable for plasmonics, biomolecule immobilisation, and nanoelectronics. Gold nano- and microstructures can be fabricated by one-step direct-write lithography process using focused electron beam induced deposition (FEBID. Typically, as-deposited gold nanostructures suffer from a low Au content and unacceptably high carbon contamination. We show that the undesirable carbon contamination can be diminished using a two-step process – a combination of optimized deposition followed by appropriate postdeposition cleaning. Starting from the common metal-organic precursor Me2-Au-tfac, it is demonstrated that the Au content in pristine FEBID nanostructures can be increased from 30 atom % to as much as 72 atom %, depending on the sustained electron beam dose. As a second step, oxygen-plasma treatment is established to further enhance the Au content in the structures, while preserving their morphology to a high degree. This two-step process represents a simple, feasible and high-throughput method for direct writing of purer gold nanostructures that can enable their future use for demanding applications.

Athabasca basin unconformity-type uranium deposits. A special class of sandstone-type deposits

International Nuclear Information System (INIS)

Hoeve, J.

1980-01-01

Two major episodes of uranium metallogenesis are recognized in Northern Saskatchewan. The first is of late-Hudsonian age and gave rise to metamorphic-hydrothermal pitchblende deposits of simple mineralogy at Beaverlodge (primary mineralization: 1780+-20 m.y.). The second and more important episode of approximately Grenvillian age rendered unconformity-type deposits in the Athabasca Basin (primary mineralization: 1000-1300 m.y.). The late-Hudsonian deposits at Beaverlodge were overprinted by this second event and new deposits of complex mineralogy were formed in that area. The metallogenetic importance of a third and much later episode which gave rise to mineralization within the Athabasca Formation is uncertain at the moment. With regards to metallogenesis of the unconformity-type deposits, presently available evidence favours a diagenetic-hydrothermal rather than a near-surface supergene or a magmatic/metamorphic hydrothermal model. The diagenetic-hydrothermal model relates uranium mineralization to 'red bed-type' diagenetic processes in the Athabasca Formation involving post-depositional oxidation and leaching, which continued for several hundred million years after deposition. Ore deposits were formed by interaction, under conditions of deep burial at elevated temperatures and pressures, of a uraniferous oxidizing Athabasca aquifer with reducing, graphite-bearing, metamorphic rocks of the basin floor. The large-scale convection required for such interaction may have been induced by mafic magmatic activity coeval with the episode of mineralization. The diagenetic-hydrothermal model displays close similarities with metallogenetic models developed for certain sandstone-type deposits. (author)

World Distribution of Uranium Deposits (UDEPO) with uranium deposit classification. 2009 ed

International Nuclear Information System (INIS)

2009-10-01

The World Distribution of Uranium Deposits (UDEPO) database provides general, technical and geological information, including references, about the worldwide uranium deposits. UDEPO has been published on the internet which allows the users to register freely and to work with datasets (http://www-nfcis.iaea.org). The UDEPO web site is designed to allow users to retrieve data sets on a variety of deposit related topics ranging from specific information on individual uranium deposits to statistical information on uranium deposits worldwide. The basic building blocks for the UDEPO database are the more than 900 individual deposits for which information is available in the database. The database is arranged in a relational database format which has one main table and a number of associated tables. Structured nature of the database allows filtering and querying the database in more systematic way. The web site provides filtering and navigation to the data from the database. It has also a statistical tool which provides summary information on number of deposits and uranium resources by type and status, and by country and status. In this respect and with regard to the data presented, the UDEPO database is a unique database which provides freely accessible information on worldwide uranium deposits. Although a great effort is spent to have complete and accurate database, the users should take into consideration that there still might be missing or outdated data for individual deposits due to the rapid changes in the uranium industry due to the new exploration works which are ongoing everyday. This document and its supplementary CD-ROM represent a snapshot of the status of the database as of the end of 2008. However, the database is being continuously updated and the latest updates and additions can be accessed from the database web site (http://wwwnfcis.iaea.org)

Geologic factors of hydrogenic uranium deposit formation are considered. Structural, formation and lithological-facies factors of deposit formation, connected with zones of stratal oxidation, are characterized. Peculiarities of deposit localization, connected with orogenic structures of Mesozoic and lenozoic age, are described. It is noted that deposits of anagenous group are widely spread in Paleozoic formations, infiltration uranium deposits are localized mainly in Cenozoic sediments, while uranium mineralization both anagenous and infiltration groups are widely developed in Mesozoic sediments. Anagenous deposits were formed in non-oxygen situation, their age varies from 200 to 55 mln years. Infiltration deposit formation is determined by asymmetric oxidation zonation, their age varies from 10 - 40 mln years to dozens of thousand years [ru

The effect of written text on comprehension of spoken English as a foreign language.

Diao, Yali; Chandler, Paul; Sweller, John

2007-01-01

Based on cognitive load theory, this study investigated the effect of simultaneous written presentations on comprehension of spoken English as a foreign language. Learners' language comprehension was compared while they used 3 instructional formats: listening with auditory materials only, listening with a full, written script, and listening with simultaneous subtitled text. Listening with the presence of a script and subtitles led to better understanding of the scripted and subtitled passage but poorer performance on a subsequent auditory passage than listening with the auditory materials only. These findings indicated that where the intention was learning to listen, the use of a full script or subtitles had detrimental effects on the construction and automation of listening comprehension schemas.

Stratigraphic implications of uranium deposits

International Nuclear Information System (INIS)

Langford, F.F.

1980-01-01

One of the most consistent characteristics of economic uranium deposits is their restricted stratigraphic distribution. Uraninite deposited with direct igneous affiliation contains thorium, whereas chemical precipitates in sedimentary rocks are characterized by thorium-free primary uranium minerals with vanadium and selenium. In marine sediments, these minerals form low-grade disseminations; but in terrestrial sediments, chiefly fluvial sandstones, the concentration of uranium varies widely, with the high-grade portions constituting ore. Pitchblende vein deposits not only exhibit the same chemical characteristics as the Colorado-type sandstone deposits, but they have a stratigraphically consistent position at unconformities covered by fluvial sandstones. If deposits in such diverse situations have critical features in common, they are likely to have had many features of their origin in common. Thus, vein deposits in Saskatchewan and Australia may have analogues in areas that contain Colorado-type sandstone deposits. In New Mexico, the presence of continental sandstones with peneconformable uranium deposits should also indicate good prospecting ground for unconformity-type vein deposits. All unconformities within the periods of continental deposition ranging from Permian to Cretaceous should have uranium potential. Some situations, such as the onlap of the Abo Formation onto Precambrian basement in the Zuni Mountains, may be directly comparable to Saskatchewan deposition. However, uranium occurrences in the upper part of the Entrada Sandstone suggest that unconformities underlain by sedimentary rocks may also be exploration targets

Subordinated clauses usage and assessment of syntactic maturity: A comparison of oral and written retellings in beginning writers

Directory of Open Access Journals (Sweden)

Verónica Sánchez Abchi

2010-03-01

Full Text Available The present longitudinal study aims to explore possible syntactic complexity differences between oral and written story retellings produced by Spanish speaking children at the end of the 1st and 2nd grades of primary education. It is assumed that differences between oral and written modalities can be found due in part to the cognitive demands of low level writing skills. Indeed, it has been observed that written texts produced by children are shorter and of lower quality than oral ones (Berninger, et al., , 1992; Berninger & Swanson,1994. However, how the transcription skills might constrain the syntactic complexity of children’s written texts is not well established.The children (N=163 that participated in this study were attending three different schools located in Córdoba Province, Argentina. The children were examined at the end of the 1st and 2nd year of primary education. The oral and written retellings were analyzed using Length, T- unit number and Syntactic Complexity Index (SCI (Hunt, 1965; 1970. The analysis of children’s productions showed differences between grades and modalities. The differences between modalities were found in text Length and T-unit, but not in SCI. These results suggest that transcription skills do not affect syntactic performance. Nevertheless, a more detailed analysis revealed differences between groups. Possible restrictions of the original text on children’s performance were also observed. The implications and the scope of the SCI and units used for the analysis are furthered discussed.

Roberts, Ralph Jackson; Irving, Earl Montgomery; Simons, F.S.

1957-01-01

The mineral deposits of Central America were studied between 1942 and 1945, in cooperation with the United States Department of State and the Foreign Economic Administration. Emphasis was originally placed on the study of strategic-mineral deposits, especially of antimony, chromite, manganese, quartz, and mica, but deposits of other minerals that offered promise of significant future production were also studied. A brief appraisal of the base-metal deposits was made, and deposits of iron ore in Honduras and of lead and zinc ores in Guatemala were mapped. In addition, studies were made of the regional geology of some areas, data were collected from many sources, and a new map of the geology of Central America was compiled.

Written production of learners of Portuguese as an additional foreign language: referentiation as a sociocognitive processing resource

Directory of Open Access Journals (Sweden)

Lucia Rottava

2011-12-01

Full Text Available This article discusses referentiation in texts written by learners of Portuguese as an additional foreign language. Referentiation consists of construction and reconstruction of discourse objects, a product that results from cognitive and interactive activity. Among forms of interaction, written production is an interactive process as meanings derive from the interaction between writer/reader and text in complex and multifaceted experiences that involve prior experiences and/or knowledge, besides the interlocutor’s discursive purpose. Therefore, the text is the result of an action ‘under construction’ made possible through the use of language. Data for this article come from written production developed in classes of Portuguese as a foreign language. The findings reveal learners’ textual processing and its peculiarities resulting from the learners’ proficiency levels and the requirements of the type and theme of the specified task.

PRAGMATIC AND RHETORICAL STRATEGIES IN THE ENGLISH-WRITTEN JOKES

Directory of Open Access Journals (Sweden)

Dyah Rochmawati

2017-05-01

Full Text Available Understanding verbal jokes in English is problematic for English as Foreign Language (EFL readers since understanding the jokes requires understanding their linguistic, cultural and social elements. Since a joke constitutes a complex and paradoxical phenomenon, it needs multiple approaches of analyses—such as pragmatic and rhetorical analyses—in order to investigate the multiple layers of meanings it carries. Recently there has been a shift in humor studies, emphasizing linguistic humors and involving the field of rhetoric. These studies, however, have mostly addressed the connection between rhetoric and spoken jokes in persuasion. The present study therefore applied Austin’s Speech Act Theory (1975 and Grice’s Cooperative Principles (1957, and Berger’s rhetorical techniques (1993 to crack the funniness of the written jokes. Specifically, the study aims at describing: how the (1 rhetorical and (2 pragmatic strategies are used in the jokes, and (3 how the pragmatic and rhetorical strategies complement to create humor. The study employed a qualitative research method. Some jokes were purposively selected from the Reader’s Digest and two online sources: http://jokes.cc.com/, and http://www.ajokeaday.com/. Document studies were the means of data collection. The collected data were then analyzed using a qualitative content analysis. The results showed that that there was a relationship between the two pragmatic theories, i.e., Speech Act Theory and Cooperative Principles, and Berger’s rhetorical techniques. The results offered an alternative reading and richer understanding of how written jokes employed pragmatic and rhetorical strategies to advance their rhetorical objectives and humor functions.

In-situ CdS/CdTe Heterojuntions Deposited by Pulsed Laser Deposition

KAUST Repository

Avila-Avendano, Jesus

2016-04-09

In this paper pulsed laser deposition (PLD) methods are used to study p-n CdTe/CdS heterojunctions fabricated in-situ. In-situ film deposition allows higher quality p-n interfaces by minimizing spurious contamination from the atmosphere. Morphologic and structural analyses were carried for CdTe films deposited on various substrates and different deposition conditions. The electrical characteristics and performance of the resulting p-n heterojunctions were studied as function of substrate and post-deposition anneal temperature. In-situ growth results on diodes with a rectification factor of ~ 105, an ideality factor < 2, and a reverse saturation current ~ 10-8 A. The carrier concentration in the CdTe film was in the range of ~ 1015 cm-3, as measured by C-V methods. The possible impact of sulfur diffusion from the CdS into the CdTe film is also investigated using High Resolution Rutherford Back-Scattering.

2017-05-16

Methods and compositions for additive manufacturing that include reactive or thermosetting polymers, such as urethanes and epoxies. The polymers are melted, partially cross-linked prior to the depositing, deposited to form a component object, solidified, and fully cross-linked. These polymers form networks of chemical bonds that span the deposited layers. Application of a directional electromagnetic field can be applied to aromatic polymers after deposition to align the polymers for improved bonding between the deposited layers.

Arc-related porphyry molybdenum deposit model: Chapter D in Mineral deposit models for resource assessment

Zarei, Gholam Reza; Pourghasemian, Hossein; Jalali, Hassan

2017-06-01

The present study attempts to give an account of how students represent writing task in an EAP course. Further, the study is intended to discover if learners' mental representation of writing would contribute to their written performance. During a 16-week term, students were instructed to practice writing as a problem solving activity. At almost the end of the term, they were prompted to write on what they thought writing task was like and also an essay on an argumentative topic. The results revealed that students could conceptualize the instructed recursive model of writing as a process-based, multi-dimensional and integrated activity inducing self-direction and organization while holding in low regard the product view of writing. The findings also demonstrated that task representation was related to the students' writing performance, with process oriented students significantly outperforming the product-oriented ones. Also, it was found that task representation components (ideational, linguistic, textual, interpersonal) had a significant relationship with the written performance ([Formula: see text]; Sig.: 0.006). The study can have both theoretical and practical implications with regard to the factors involving the students' writing internal processes and their effects on written performance.

ELLIPT2D: A Flexible Finite Element Code Written Python

International Nuclear Information System (INIS)

Pletzer, A.; Mollis, J.C.

2001-01-01

The use of the Python scripting language for scientific applications and in particular to solve partial differential equations is explored. It is shown that Python's rich data structure and object-oriented features can be exploited to write programs that are not only significantly more concise than their counter parts written in Fortran, C or C++, but are also numerically efficient. To illustrate this, a two-dimensional finite element code (ELLIPT2D) has been written. ELLIPT2D provides a flexible and easy-to-use framework for solving a large class of second-order elliptic problems. The program allows for structured or unstructured meshes. All functions defining the elliptic operator are user supplied and so are the boundary conditions, which can be of Dirichlet, Neumann or Robbins type. ELLIPT2D makes extensive use of dictionaries (hash tables) as a way to represent sparse matrices.Other key features of the Python language that have been widely used include: operator over loading, error handling, array slicing, and the Tkinter module for building graphical use interfaces. As an example of the utility of ELLIPT2D, a nonlinear solution of the Grad-Shafranov equation is computed using a Newton iterative scheme. A second application focuses on a solution of the toroidal Laplace equation coupled to a magnetohydrodynamic stability code, a problem arising in the context of magnetic fusion research

Oral and Written Expression in Children With Reading Comprehension Difficulties.

Carretti, Barbara; Motta, Eleonora; Re, Anna Maria

2016-01-01

Several studies have highlighted that children with reading comprehension difficulties also have problems in tasks that involve telling a story, in writing or verbally. The main differences identified regard poor comprehenders' lower level of coherence in their productions by comparison with good comprehenders. Only one study has compared poor and good comprehenders' performance in both modalities (oral and written), however, to see whether these modalities differently influence poor comprehenders' performance. We qualitatively and quantitatively compared the performance of good and poor comprehenders in oral and written narrative tasks with the aim of shedding light on this issue. Regression analyses were also used to explore the role of working memory and vocabulary in explaining individual differences. Our results showed that the two groups produced narratives of comparable length, with similar percentages of spelling mistakes, whereas they differed in terms of the quality of their narratives, regardless of the modality. These differences were qualified by analyzing the children's use of connective devices, and poor comprehenders were found to use a higher proportion of additive devices than good comprehenders. Regression analyses showed that working memory (particularly the intrusion errors measure) explained a modest part of the qualitative differences in narrative production. Implications for our theoretical understanding of poor comprehenders' profiles and education are discussed. © Hammill Institute on Disabilities 2014.

Quartz-pebble-conglomerate gold deposits: Chapter P in Mineral deposit models for resource assessment

Science.gov (United States)

Taylor, Ryan D.; Anderson, Eric D.

2018-05-17

Quartz-pebble-conglomerate gold deposits represent the largest repository of gold on Earth, largely due to the deposits of the Witwatersrand Basin, which account for nearly 40 percent of the total gold produced throughout Earth’s history. This deposit type has had a controversial history in regards to genetic models. However, most researchers conclude that they are paleoplacer deposits that have been modified by metamorphism and hydrothermal fluid flow subsequent to initial sedimentation.The deposits are found exclusively within fault-bounded depositional basins. The periphery of these basins commonly consists of granite-greenstone terranes, classic hosts for lode gold that source the detrital material infilling the basin. The gold reefs are typically located along unconformities or, less commonly, at the top of sedimentary beds. Large quartz pebbles and heavy-mineral concentrates are found associated with the gold. Deposits that formed prior to the Great Oxidation Event (circa 2.4 giga-annum [Ga]) contain pyrite, whereas younger deposits contain iron oxides. Uranium minerals and hydrocarbons are also notable features of some deposits.Much of the gold in these types of deposits forms crystalline features that are the product of local remobilization. However, some gold grains preserve textures that are undoubtedly of detrital origin. Other heavy minerals, such as pyrite, contain growth banding that is truncated along broken margins, which indicates that they were transported into place as opposed to forming by in situ growth in a hydrothermal setting.The ore tailings associated with these deposits commonly contain uranium-rich minerals and sulfides. Oxidation of the sulfides releases sulfuric acid and mobilizes various metals into the environment. The neutralizing potential of the tailings is minimal, since carbonate minerals are rare. The continuity of the tabular ore bodies, such as those of the Witwatersrand Basin, has allowed these mines to be the deepest in

In this document results from the Greater Manchester Acid Deposition Survey (GMADS), an urban precipitation chemistry network, for 1990 are presented. Full analytical methods are described along with the precision and accuracy of the methods used. The spatial variability of precipitation chemistry and deposition over this urban region was investigated using a network of twenty collectors. Concentrations of non marine sulphate, ammonium, calcium and hydrogen, and nitrogen dioxide gas concentrations all show significant spatial variability. The spatial variability of the deposition rates of non marine sulphate, nitrate, ammonium, hydrogen and calcium were significant. (Author).

Shared written case formulations and weight change in outpatient therapy for anorexia nervosa: a naturalistic single case series.

Science.gov (United States)

Gladwin, Alice M; Evangeli, Michael

2013-01-01

The therapeutic effects of written shared case formulations are underexplored and have not been examined in anorexia nervosa. This study explored the relationship between (a) the delivery (b) the quality of a shared written case formulation and weight in outpatient psychological therapy for anorexia nervosa. A naturalistic single case series approach was used to examine the case notes of women who had attended a specialist eating disorders service over a 2-year period. The case notes of 15 adult women who had undergone outpatient psychological therapy for anorexia nervosa with a shared written case formulation component were reviewed. The impact of the quality of the case formulation on weekly weight was examined for 14 of the clients where the case formulation was available. The nature of the relationship between the delivery of the written shared case formulation and weight was examined for all 15 clients. There was some evidence to support an association between delivery of the shared written case formulation and weight changes (both weight gain [five out of 15 clients] and weight loss [three out of 15 clients]) in individual cases. Higher case formulation quality was related to cases where weight change did not occur. The delivery of case formulations can be associated with important therapeutic change (both beneficial and potentially harmful) in anorexia nervosa. Future research into the causal mechanisms associated with sharing formulations will face the challenge of adopting strategies that allow for an in-depth exploration of complex therapy variables whilst overcoming methodological challenges.

Post-depositional fracturing and subsidence of pumice flow deposits: Lascar Volcano, Chile.

Science.gov (United States)

Whelley, Patrick L; Jay, J; Calder, E S; Pritchard, M E; Cassidy, N J; Alcaraz, S; Pavez, A

Unconsolidated pyroclastic flow deposits of the 1993 eruption of Lascar Volcano, Chile, have, with time, become increasingly dissected by a network of deeply penetrating fractures. The fracture network comprises orthogonal sets of decimeter-wide linear voids that form a pseudo-polygonal grid visible on the deposit surface. In this work, we combine shallow surface geophysical imaging tools with remote sensing observations and direct field measurements of the deposit to investigate these fractures and their underlying causal mechanisms. Based on ground penetrating radar images, the fractures are observed to have propagated to depths of up to 10 m. In addition, orbiting radar interferometry shows that deposit subsidence of up to 1 cm/year -1 occurred between 1993 and 1996 with continued subsidence occurring at a slower rate thereafter. In situ measurements show that 1 m below the surface, the 1993 deposits remain 5°C to 15°C hotter, 18 years after emplacement, than adjacent deposits. Based on the observed subsidence as well as estimated cooling rates, the fractures are inferred to be the combined result of deaeration, thermal contraction, and sedimentary compaction in the months to years following deposition. Significant environmental factors, including regional earthquakes in 1995 and 2007, accelerated settling at punctuated moments in time. The spatially variable fracture pattern relates to surface slope and lithofacies variations as well as substrate lithology. Similar fractures have been reported in other ignimbrites but are generally exposed only in cross section and are often attributed to formation by external forces. Here we suggest that such interpretations should be invoked with caution, and deformation including post-emplacement subsidence and fracturing of loosely packed ash-rich deposits in the months to years post-emplacement is a process inherent in the settling of pyroclastic material.

Investigating the impact of SMS speak on the written work of English first language and English second language high school learners

Directory of Open Access Journals (Sweden)

Winzker, Kristy

2009-12-01

Full Text Available This study examined the impact of SMS speak on the written work of English first language (L1 and English second language (L2 grade 8s and 11s. The aim was to establish whether these learners make use of features of SMS speak in their English written work. The participants, 88 learners from an English-Afrikaans dual medium school, completed questionnaires from which the frequency and volume of their SMS use were determined, as well as the features of SMS speak they reportedly use while SMSing. In addition, samples of their English essays were examined for the following features of SMS speak: (deliberate spelling errors; lack of punctuation; over-punctuation; omission of function words; and use of abbreviation, acronyms, emoticons and rebus writing. The questionnaires indicated that these learners are avid users of the SMS. All participants reported using features of SMS speak in their SMSes, and more than 40% reported using SMS speak in their written school work. Despite this, features of SMS speak infrequently occurred in the written work of the learners, which could indicate that the learners are able to assess when it is and is not appropriate to use a certain variety of language. That said, a number of SMS speak features were indeed present in the samples, which indicates that SMS speak had some impact on the written work of these learners. Not all of the nonstandard features of their written English could, however, necessarily be attributed to the influence of SMS speak; specifically some of the spelling and punctuation errors could have occurred in the written English of high school learners from before the advent of cell phones.

Low-fluorine Stockwork Molybdenite Deposits

Science.gov (United States)

Ludington, Steve; Hammarstrom, Jane; Piatak, Nadine M.

2009-01-01

Low-fluorine stockwork molybdenite deposits are closely related to porphyry copper deposits, being similar in their tectonic setting (continental volcanic arc) and the petrology (calc-alkaline) of associated igneous rock types. They are mainly restricted to the Cordillera of western Canada and the northwest United States, and their distribution elsewhere in the world may be limited. The deposits consist of stockwork bodies of molybdenite-bearing quartz veinlets that are present in and around the upper parts of intermediate to felsic intrusions. The deposits are relatively low grade (0.05 to 0.2 percent Mo), but relatively large, commonly >50 million tons. The source plutons for these deposits range from granodiorite to granite in composition; the deposits primarily form in continental margin subduction-related magmatic arcs, often concurrent with formation of nearby porphyry copper deposits. Oxidation of pyrite in unmined deposits or in tailings and waste rock during weathering can lead to development of acid-rock drainage and limonite-rich gossans. Waters associated with low-fluorine stockwork molybdenite deposits tend to be nearly neutral in pH; variable in concentrations of molybdenum (10,000 ug/L); below regulatory guidelines for copper, iron, lead, zinc, and mercury; and locally may exceed guidelines for arsenic, cadmium, and selenium.

Development and evaluation of a long-term deposit probe for on-line monitoring of deposit growth

2007-12-15

A newly designed air-cooled probe for on-line monitoring of deposition growth has been tested in a boiler firing three woody fuels. Thermocouples are mounted on both sides of the tube wall enabling measurements of the heat flux through the probe wall. Knowing the heat flux through the probe wall, it is possible to measure the additional heat transfer resistance caused by the deposit and to estimate the properties of the deposit. Calculating the deposit thickness using the collected temperature data indicated the thinnest deposit when wood was fired, followed by bark and waste wood. The calculated deposit thickness was larger than those found when analysing the deposit thickness after the probe had been removed. Nevertheless, the ranking of fuels by deposit build-up rate was the same. (author)

This study aims to review the relationship between written language skills and factors which are thought to affect this skill such as mean hearing loss, duration of auditory deprivation, speech discrimination score, and pre-school education attendance and socioeconomic status of hearing impaired children who attend 4th-7th grades in primary school in inclusive environment. The study included 25 hearing impaired children (14 males, 11 females; mean age 11.4±1.4 years; range 10 to 14 years) (study group) and 20 children (9 males, 11 females; mean age 11.5±1.3 years; range 10 to 14 years) (control group) with normal hearing in the same age group and studying in the same class. Study group was separated into two subgroups as group 1a and group 1b since some of the children with hearing disability used hearing aid while some used cochlear implant. Intragroup comparisons and relational screening were performed for those who use hearing aids and cochlear implants. Intergroup comparisons were performed to evaluate the effect of the parameters on written language skills. Written expression skill level of children with hearing disability was significantly lower than their normal hearing peers (p=0.001). A significant relationship was detected between written language skills and mean hearing loss (p=0.048), duration of auditory deprivation (p=0.021), speech discrimination score (p=0.014), and preschool attendance (p=0.005), when it comes to socioeconomic status we were not able to find any significant relationship (p=0.636). It can be said that hearing loss affects written language skills negatively and hearing impaired individuals develop low-level written language skills compared to their normal hearing peers.

Dry deposition on urban surfaces

1985-01-01

In order to facilitate developing a model for deposition in urban areas, beryllium-7, created by cosmic radiation and fall-out cesium-137, have been used as tracers in measurements designed to find the dry deposition velocity on building surfaces. A literature review has revealed that very little work has been done on deposition in urban areas; therefore, a major effort on meausring the deposition parameter is needed to construct reliable models in this field. Deposition velocities in the range from 0.001-0.04 cm/s have been found. (author)

Dumas, Audrée-Anne; Lemieux, Simone; Lapointe, Annie; Dugrenier, Marilyn; Desroches, Sophie

2017-06-01

This purpose of this study was to compare the nutritional content of vegetarian recipes published in food blogs written by registered dietitians (RDs) and by non-registered dietitians (non-RDs). Twelve food blogs written by RDs and 12 written by non-RDs were selected using a systematic approach. For each food blog, 2 vegetarian entrée recipes per season were selected (n = 192 recipes). Descriptive analyses were performed using Fisher's exact test. Median nutritional values per serving between RDs' and non-RDs' recipes were compared using Wilcoxon-Mann-Whitney tests. RDs' recipes were significantly lower in energy, non-heme iron, vitamin C, and sodium, contained significantly more vitamin D and had a higher protein proportion than non-RDs' recipes. Disparities were also observed across type of entrée and vegetarian dietary pattern. In conclusion, this study showed that RD and non-RD food bloggers provided vegetarian recipes with few nutritional differences. Whether expanding the comparative analysis between RDs and non-RDs' blogs targeting different nutrition-related topics would yield different results remains to be investigated.

2003-01-01

This is the second of two special issues of Economic Geology devoted to gold deposits in northern Nevada. Readers interested in a general overview of these deposits, their economic significance, their context within the tectonic evolution of the region, and synoptic references on each gold deposit type are directed to the preface of the first special issue (John et al., 2003). Volume 98, issue 2, contains five papers that address regional aspects important to the genesis of gold deposits in northern Nevada and five papers that present detailed studies of epithermal deposits and districts. All of the regional papers are pertinent to Carlin-type gold deposits, because they address the age of mineralization (Arehart et al., 2003), origin and evolutionary history of the northwest-striking mineral belts that localize many deposits (Grauch et al., 2003), nature of the middle and lower crust below these mineral belts (Howard, 2003), district- to deposit-scale stream sediment and lithogeochemical anomalies (Theodore et al., 2003), and stratigraphy and structure of a district located along a northeast-striking lineament (Peters et al., 2003).

Deposits of the Peruvian Pisco Formation are morphologically similar to the mounds of Juventae Chasma at the equatorial region on Mars (Fig. 1). By analyzing these deposits, we hope to gain information about the environmental conditions that prevailed during sediment deposition and erosion, hence conditions that might be applicable to the Martian layered and hydrated deposits. Mariner 9 data of the Martian mid-latitudes have already shown evidence of the wind-sculptured landforms that display the powerful prevailing eolian regime [1]. In addition, [2] reported on similarities between Martian erosional landforms and those of the rainless coastal desert of central Peru from the Paracas peninsula to the Rio Ica. As indicated by similar erosional patterns, hyper-arid conditions and unidirectional winds must have dominated at least after deposition of the sediments, which are intermixed volcaniclastic materials and evaporate minerals at both locations. Likewise, variations in composition are displayed by alternating layers of different competence. The Pisco formation bears yardangs on siltstones, sandstones and clays with volcaniclastic admixtures [3] whereas the presence of sulphate minerals and the omnipresent mafic mineralogy has been reported for the layered mounds of Juventae Chasma equally [4]. Likewise, a volcanic airfall deposition and lacustrine formation have been proposed for the sulphate-rich deposits of Juventae Chasma [5,6]. In order to find out about potential spectral similarities, we performed a detailed spectral analysis of the surface by using LANDSAT and Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) VNIR/ SWIR data (visible to near-infrared and shortwave infrared region).

The National Uranium Resource Evaluation (NURE) Program has sponsored uranium deposit model studies by Bendix Field Engineering Corporation (Bendix), the US Geological Survey (USGS), and numerous subcontractors. This paper deals only with models from the following six reports prepared by Samuel S. Adams and Associates: GJBX-1(81) - Geology and Recognition Criteria for Roll-Type Uranium Deposits in Continental Sandstones; GJBX-2(81) - Geology and Recognition Criteria for Uraniferous Humate Deposits, Grants Uranium Region, New Mexico; GJBX-3(81) - Geology and Recognition Criteria for Uranium Deposits of the Quartz-Pebble Conglomerate Type; GJBX-4(81) - Geology and Recognition Criteria for Sandstone Uranium Deposits in Mixed Fluvial-Shallow Marine Sedimentary Sequences, South Texas; GJBX-5(81) - Geology and Recognition Criteria for Veinlike Uranium Deposits of the Lower to Middle Proterozoic Unconformity and Strata-Related Types; GJBX-6(81) - Geology and Recognition Criteria for Sandstone Uranium Deposits of the Salt Wash Type, Colorado Plateau Province. A unique feature of these models is the development of recognition criteria in a systematic fashion, with a method for quantifying the various items. The recognition-criteria networks are used in this paper to illustrate the various types of deposits

Written communication skills are integral to patient care handoffs. Residency programs require feasible assessment tools that provide timely formative and summative feedback, ideally linked to the Accreditation Council for Graduate Medical Education Milestones. We describe the use of 1 such tool-UPDATED-to assess written handoff communication skills in internal medicine interns. During 2012-2013, the authors piloted a structured practice audit at 1 academic institution to audit written sign-outs completed by 45 interns, using the UPDATED tool, which scores 7 aspects of sign-out communication linked to milestones. Intern sign-outs were audited by trained faculty members throughout the year. Results were incorporated into intern performance reviews and Clinical Competency Committees. A total of 136 sign-outs were audited (averaging 3.1 audits per intern). In the first trimester, 14 interns (31%) had satisfactory audit results. Five interns (11%) had critical deficiencies and received immediate feedback, and the remaining 26 (58%) were assigned future audits due to missing audits or unsatisfactory scores. In the second trimester, 21 interns (68%) had satisfactory results, 1 had critical deficiencies, and 9 (29%) required future audits. Nine of the 10 remaining interns in the final trimester had satisfactory audits. Faculty time was estimated at 10 to 15 minutes per sign-out audited. The UPDATED audit is a milestone-based tool that can be used to assess written sign-out communication skills in internal medicine residency programs. Future work is planned to adapt the tool for use by senior supervisory residents to appraise sign-outs in real time.

1976-01-01

Deposition of NpO 2 and UO 2 thin films over an area of 7.5 to 10 cm diam has become a routine operation in preparation of fission chamber plates. Vacuum evaporation or electroplating has been used for this purpose. The ''paint brush'' technique has been used as well; however, uniformity requirements normally eliminate this procedure. Vapor deposition in vacuum appears to be the most suitable technique for preparing NpO 2 and UO 2 deposits of >200 cm 2 . This paper describes the procedures used in preparing uniform large area deposits of NpO 2 (approximately 300 cm 2 ) and UO 2 (approximately 2000 cm 2 ) by vacuum evaporation using electron bombardment heating and several substrate motion and heating methods to achieve uniformity and adhesion

Precambrian uranium deposits as a possible source of uranium for the European Variscan deposits

International Nuclear Information System (INIS)

Mineeva, I.G.; Klochkov, A.S.

2002-01-01

The Precambrian uranium deposits have been studied on the territory of Baltic and Ukrainian shields. The primary Early Proterozoic complex Au-U deposits originated in granite-greenstone belts as a result of their evolution during continental earth crust formation by prolonged rift genesis. The greenstone belts are clues for revealing ancient protoriftogenic structures. The general regularities of uranium deposition on Precambrian shields are also traceable in Variscan uranium deposits from the Bohemian massif. The Variscan period of uranium ore formation is connected with a polychronous rejuvenation of ancient riftogenous systems and relatively younger processes of oil and gas formation leading to the repeated mobilization of U from destroyed Proterozoic and Riphean uranium deposits.

Nishimori, R.K.; Ragland, P.C.; Rogers, J.J.W.; Greenberg, J.K.

1977-01-01

This report is a review of published data bearing on the geology and origin of uranium deposits in granitic, pegmatitic and migmatitic rocks with the aim of assisting in the development of predictive criteria for the search for similar deposits in the U.S. Efforts were concentrated on the so-called ''porphyry'' uranium deposits. Two types of uranium deposits are primarily considered: deposits in pegmatites and alaskites in gneiss terrains, and disseminations of uranium in high-level granites. In Chapter 1 of this report, the general data on the distribution of uranium in igneous and metamorphic rocks are reviewed. Chapter 2 contains some comments on the classification of uranium deposits associated with igneous rocks and a summary of the main features of the geology of uranium deposits in granites. General concepts of the behavior of uranium in granites during crustal evolution are reviewed in Chapter 3. Also included is a discussion of the relationship of uranium mineralization in granites to the general evolution of mobile belts, plus the influence of magmatic and post-magmatic processes on the distribution of uranium in igneous rocks and related ore deposits. Chapter 4 relates the results of experimental studies on the crystallization of granites to some of the geologic features of uranium deposits in pegmatites and alaskites in high-grade metamorphic terrains. Potential or favorable areas for igneous uranium deposits in the U.S.A. are delineated in Chapter 5. Data on the geology of specific uranium deposits in granitic rocks are contained in Appendix 1. A compilation of igneous rock formations containing greater than 10 ppM uranium is included in Appendix 2. Appendix 3 is a report on the results of a visit to the Roessing area. Appendix 4 is a report on a field excursion to eastern Canada

China is experiencing intense air pollution caused in large part by anthropogenic emissions of reactive nitrogen. These emissions result in the deposition of atmospheric nitrogen (N) in terrestrial and aquatic ecosystems, with implications for human and ecosystem health, greenhouse gas balances and biological diversity. However, information on the magnitude and environmental impact of N deposition in China is limited. Here we use nationwide data sets on bulk N deposition, plant foliar N and crop N uptake (from long-term unfertilized soils) to evaluate N deposition dynamics and their effect on ecosystems across China between 1980 and 2010. We find that the average annual bulk deposition of N increased by approximately 8 kilograms of nitrogen per hectare (P < 0.001) between the 1980s (13.2 kilograms of nitrogen per hectare) and the 2000s (21.1 kilograms of nitrogen per hectare). Nitrogen deposition rates in the industrialized and agriculturally intensified regions of China are as high as the peak levels of deposition in northwestern Europe in the 1980s, before the introduction of mitigation measures. Nitrogen from ammonium (NH4+) is the dominant form of N in bulk deposition, but the rate of increase is largest for deposition of N from nitrate (NO3-), in agreement with decreased ratios of NH3 to NOx emissions since 1980. We also find that the impact of N deposition on Chinese ecosystems includes significantly increased plant foliar N concentrations in natural and semi-natural (that is, non-agricultural) ecosystems and increased crop N uptake from long-term-unfertilized croplands. China and other economies are facing a continuing challenge to reduce emissions of reactive nitrogen, N deposition and their negative effects on human health and the environment.

Breakthrough to Non-Vacuum Deposition of Single-Crystal, Ultra-Thin, Homogeneous Nanoparticle Layers: A Better Alternative to Chemical Bath Deposition and Atomic Layer Deposition

Yu-Kuang Liao

2017-04-01

Full Text Available Most thin-film techniques require a multiple vacuum process, and cannot produce high-coverage continuous thin films with the thickness of a few nanometers on rough surfaces. We present a new ”paradigm shift” non-vacuum process to deposit high-quality, ultra-thin, single-crystal layers of coalesced sulfide nanoparticles (NPs with controllable thickness down to a few nanometers, based on thermal decomposition. This provides high-coverage, homogeneous thickness, and large-area deposition over a rough surface, with little material loss or liquid chemical waste, and deposition rates of 10 nm/min. This technique can potentially replace conventional thin-film deposition methods, such as atomic layer deposition (ALD and chemical bath deposition (CBD as used by the Cu(In,GaSe2 (CIGS thin-film solar cell industry for decades. We demonstrate 32% improvement of CIGS thin-film solar cell efficiency in comparison to reference devices prepared by conventional CBD deposition method by depositing the ZnS NPs buffer layer using the new process. The new ZnS NPs layer allows reduction of an intrinsic ZnO layer, which can lead to severe shunt leakage in case of a CBD buffer layer. This leads to a 65% relative efficiency increase.

Ettlinger, Rebecca Bolt

This thesis concerns the deposition of thin films for solar cells using pulsed laser deposition (PLD) and pulsed electron deposition (PED). The aim was to deposit copper tin sulfide (CTS) and zinc sulfide (ZnS) by pulsed laser deposition to learn about these materials in relation to copper zinc tin...... time. We compared the results of CZTS deposition by PLD at DTU in Denmark to CZTS made by PED at IMEM-CNR, where CIGS solar cells have successfully been fabricated at very low processing temperatures. The main results of this work were as follows: Monoclinic-phase CTS films were made by pulsed laser...... deposition followed by high temperature annealing. The films were used to understand the double band gap that we and other groups observed in the material. The Cu-content of the CTS films varied depending on the laser fluence (the laser energy per pulse and per area). The material transfer from...

Full Text Available Accurate technique for wax deposition detection and severity measurement on cold pipe wall is important for pipeline cleaning program. Usually these techniques are validated by conventional techniques on laboratory scale wax deposition flow loop. However conventional techniques inherent limitations and it is difficult to reproduce a predetermine wax deposit profile and hardness at designated location in flow loop. An alternative wax deposition system which integrates modified pour casting method and cold finger method is presented. This system is suitable to reproduce high volume of medium hard wax deposit in pipe with better control of wax deposit profile and hardness.

Uses of the Word “Macula” in Written English, 1400-Present

Schwartz, Stephen G.; Leffler, Christopher T.

2014-01-01

We compiled uses of the word “macula” in written English by searching multiple databases, including the Early English Books Online Text Creation Partnership, America’s Historical Newspapers, the Gale Cengage Collections, and others. “Macula” has been used: as a non-medical “spot” or “stain”, literal or figurative, including in astronomy and in Shakespeare; as a medical skin lesion, occasionally with a following descriptive adjective, such as a color (macula alba); as a corneal lesion, including the earliest identified use in English, circa 1400; and to describe the center of the retina. Francesco Buzzi described a yellow color in the posterior pole (“retina tinta di un color giallo”) in 1782, but did not use the word “macula”. “Macula lutea” was published by Samuel Thomas von Sömmering by 1799, and subsequently used in 1818 by James Wardrop, which appears to be the first known use in English. The Google n-gram database shows a marked increase in the frequencies of both “macula” and “macula lutea” following the introduction of the ophthalmoscope in 1850. “Macula” has been used in multiple contexts in written English. Modern databases provide powerful tools to explore historical uses of this word, which may be underappreciated by contemporary ophthalmologists. PMID:24913329

Bao Quanhe; Chen Chuanzhong; Wang Diangang; Liu Junming

2008-01-01

Hydroxyapatite films were produced by pulsed laser deposition from three kinds of hydroxyapatite targets and with different deposition times. A JXA-8800R electron probe microanalyzer (EPMA) with a Link ISIS300 energy spectrum analyzer was used to give the secondary electron image (SE) and determine the element composition of the films. The phases of thin film were analyzed by a D/max-γc X-ray diffractometer (XRD). The Fourier-transform infrared spectroscopy (FT-IR) was used to characterize the hydroxyl, phosphate and other functional groups. The results show that deposited films were amorphous which mainly composed of droplet-like particles and vibration of PO 4 3- groups. With the target sintering temperature deposition times increasing, the density of droplets is decreased. While with deposition times increasing, the density of droplets is increased. With the target sintering temperature and deposition time increasing, the ratio of Ca/P is increasing and higher than that of theoretical value of HA

Advanced deposition model for thermal activated chemical vapor deposition

Science.gov (United States)

Cai, Dang

Thermal Activated Chemical Vapor Deposition (TACVD) is defined as the formation of a stable solid product on a heated substrate surface from chemical reactions and/or dissociation of gaseous reactants in an activated environment. It has become an essential process for producing solid film, bulk material, coating, fibers, powders and monolithic components. Global market of CVD products has reached multi billions dollars for each year. In the recent years CVD process has been extensively used to manufacture semiconductors and other electronic components such as polysilicon, AlN and GaN. Extensive research effort has been directed to improve deposition quality and throughput. To obtain fast and high quality deposition, operational conditions such as temperature, pressure, fluid velocity and species concentration and geometry conditions such as source-substrate distance need to be well controlled in a CVD system. This thesis will focus on design of CVD processes through understanding the transport and reaction phenomena in the growth reactor. Since the in situ monitor is almost impossible for CVD reactor, many industrial resources have been expended to determine the optimum design by semi-empirical methods and trial-and-error procedures. This approach has allowed the achievement of improvements in the deposition sequence, but begins to show its limitations, as this method cannot always fulfill the more and more stringent specifications of the industry. To resolve this problem, numerical simulation is widely used in studying the growth techniques. The difficulty of numerical simulation of TACVD crystal growth process lies in the simulation of gas phase and surface reactions, especially the latter one, due to the fact that very limited kinetic information is available in the open literature. In this thesis, an advanced deposition model was developed to study the multi-component fluid flow, homogeneous gas phase reactions inside the reactor chamber, heterogeneous surface

Problems of culture of written expression in primary school

2014-01-01

Full Text Available This paper investigates the issue of the culture of written expression in primary school students. Starting from the fact that teaching practices increasingly points to the fact that knowledge of rules of writing in primary school students presents the weakest link in teaching Serbian language, we sought to describe the problem, point to the possible causes, propose measures and illustrate all this on concrete examples of students' essays. Our microinvestigation showed that primary school students display considerably poorer mastery of rules of writing than previously thought, to the extent that it presents a serious obstacle in language teaching as well as in other areas of educational process.

Full Text Available The article presents the frequency of using written and online sources as well as of electronic media during preparation of secondary school students for in-class examinations in Slovene language and literature. Within the scope of the above mentioned aspects we have controlled the of age and type of secondary school programmes. In the first part of the article the concept of information and communication technology/multimedia, the concept of e-learning and the concept of student activity are defined. In the second half of the article I present the results of the research, which show the frequency of use of written and web sources as well as of electronic media. These results have shown that with the oral examination of knowledge of grammar and literature the use of the notebook is prevalent, while with the written examination of knowledge of grammar and literature the use of the course book is predominant. The frequency of use of World Wide Web sources and electronic media increases with age and according to the level of difficultness of education programme. Thus the use of the notebook is the most prevalent in vocational schools whereas the use of the course book is predominant at the level of technical gimnazija and general gimnazija programmes.

Bonin, Patrick; Collay, Sandra; Fayol, Michel; Méot, Alain

2005-01-01

We conducted four experiments to investigate whether adults can exert attentional strategic control over nonlexical and lexical processing in written spelling to dictation. In Experiment 1, regular and irregular words were produced either in a nonword context (regular and irregular nonwords) or in a word context (high-frequency regular and irregular words), whereas in Experiment 2, the same set of words was produced either in a regular nonword or in an irregular low-frequency word context. Experiment 3 was a replication of Experiment 2 but with increased manipulation of the context. In Experiment 4, participants had to produce either under time pressure or in response to standard written spelling instructions. Regularity effects were found in all the experiments, but their size was not reliably affected by manipulations intended to increase or decrease reliance on nonlexical processing. More particularly, the results from Experiment 4 show that adults can speed up the initialization of their writing responses to a substantial degree without altering regularity effects on either latencies or spelling errors. Our findings suggest that, although adults are able to generate an internal deadline criterion of when to initialize the writing responses, nonlexical processing is a mandatory process that is not subject to attentional strategic control in written spelling to dictation.

Full Text Available Our work tries to approach the study of a corpus of children’s literature published in the adults’ Spanish press during the period from 1920 to 1939 and whose authorship is feminine. It’s fundamental aims, are therefore, to make this production visible; to analyze the different aesthetic and ideological propacals formalised in this writing and reintegrate this artistic production into the literary system which it took place, since it is born inside of this and they are the subsequent historical circumstances that isolate it and turn it into a minor writing. The work is constituted in three phases: women authors who publish in the last third of the nineteenth century; authors who published between 1900 and 1920, and authors writing between 1920 and 1939. The areas for which these women produced are are the school, the family, the woman’s associacions, the editorial, the wold of drawing, and the written press.

Recommendations for reducing ambiguity in written procedures.

Energy Technology Data Exchange (ETDEWEB)

Matzen, Laura E.

2009-11-01

Previous studies in the nuclear weapons complex have shown that ambiguous work instructions (WIs) and operating procedures (OPs) can lead to human error, which is a major cause for concern. This report outlines some of the sources of ambiguity in written English and describes three recommendations for reducing ambiguity in WIs and OPs. The recommendations are based on commonly used research techniques in the fields of linguistics and cognitive psychology. The first recommendation is to gather empirical data that can be used to improve the recommended word lists that are provided to technical writers. The second recommendation is to have a review in which new WIs and OPs and checked for ambiguities and clarity. The third recommendation is to use self-paced reading time studies to identify any remaining ambiguities before the new WIs and OPs are put into use. If these three steps are followed for new WIs and OPs, the likelihood of human errors related to ambiguity could be greatly reduced.

Effect of post-deposition implantation and annealing on the properties of PECVD deposited silicon nitride films

International Nuclear Information System (INIS)

Shams, Q.A.

1988-01-01

Recently it has been shown that memory-quality silicon nitride can be deposited using plasma enhanced chemical vapor deposition (PECVD). Nitrogen implantation and post-deposition annealing resulted in improved memory properties of MNOS devices. The primary objective of the work described here is the continuation of the above work. Silicon nitride films were deposited using argon as the carrier gas and evaluated in terms of memory performance as the charge-trapping layer in the metal-nitride-oxide-silicon (MNOS) capacitor structure. The bonding structure of PECVD silicon nitride was modified by annealing in different ambients at temperatures higher than the deposition temperature. Post-deposition ion implantation was used to introduce argon into the films in an attempt to influence the transfer, trapping, and emission of charge during write/erase exercising of the MNOS devices. Results show that the memory performance of PECVD silicon nitride is sensitive to the deposition parameters and post-deposition processing

Liquid crystals are widely used in displays for portable electronic information display. To broaden their scope for other applications like smart windows and tags, new material properties such as polarizer-free operation and tunable memory of a written state become important. Here, we describe an anhydrous nanoDNA-surfactant thermotropic liquid crystal system, which exhibits distinctive electrically controlled optical absorption, and temperature-dependent memory. In the liquid crystal isotropic phase, electric field-induced colouration and bleaching have a switching time of seconds. Upon transition to the smectic liquid crystal phase, optical memory of the written state is observed for many hours without applied voltage. The reorientation of the DNA-surfactant lamellar layers plays an important role in preventing colour decay. Thereby, the volatility of optoelectronic state can be controlled simply by changing the phase of the material. This research may pave the way for developing a new generation of DNA-based, phase-modulated, photoelectronic devices.

Gokcen, Dincer; Bae, Sang-Eun; Brankovic, Stanko R.

2011-01-01

The study of the kinetics of metal deposition via surface limited red-ox replacement of underpotentially deposited metal monolayers is presented. The model system was Pt submonolayer deposition on Au(1 1 1) via red-ox replacement of Pb and Cu UPD monolayers on Au(1 1 1). The kinetics of a single replacement reaction was studied using the formalism of the comprehensive analytical model developed to fit the open circuit potential transients from deposition experiments. The practical reaction kinetics parameters like reaction half life, reaction order and reaction rate constant are determined and discussed with their relevance to design and control of deposition experiments. The effects of transport limitation and the role of the anions/electrolyte on deposition kinetics are investigated and their significance to design of effective deposition process is discussed.

FALL3D: A computational model for transport and deposition of volcanic ash

Science.gov (United States)

Folch, A.; Costa, A.; Macedonio, G.

2009-06-01

FALL3D is a 3-D time-dependent Eulerian model for the transport and deposition of volcanic ashes and lapilli. The model solves the advection-diffusion-sedimentation (ADS) equation on a structured terrain-following grid using a second-order finite differences (FD) explicit scheme. Different parameterizations for the eddy diffusivity tensor and for the particle terminal settling velocities can be used. The code, written in FORTRAN 90, is available in both serial and parallel versions for Windows and Unix/Linux/Mac X operating systems (OS). A series of pre- and post-process utility programs and OS-dependent scripts to launch them are also included in the FALL3D distribution package. Although the model has been designed to forecast volcanic ash concentration in the atmosphere and ash loading at ground, it can also be used to model the transport of any kind of airborne solid particles. The model inputs are meteorological data, topography, grain-size distribution, shape and density of particles, and mass rate of particle injected into the atmosphere. Optionally, FALL3D can be coupled with the output of the meteorological processor CALMET, a diagnostic model which generates 3-D time-dependent zero-divergence wind fields from mesoscale forecasts incorporating local terrain effects. The FALL3D model can be a tool for short-term ash deposition forecasting and for volcanic fallout hazard assessment. As an example, an application to the 22 July 1998 Etna eruption is also presented.

Full Text Available Scientific publications written in natural language still play a central role as our knowledge source. However, due to the flood of publications, the literature survey process has become a highly time-consuming and tangled process, especially for novices of the discipline. Therefore, tools supporting the literature-survey process may help the individual scientist to explore new useful domains. Natural language processing (NLP is expected as one of the promising techniques to retrieve, abstract, and extract knowledge. In this contribution, NLP is firstly applied to the literature of chemical vapor deposition (CVD, which is a sub-discipline of materials science and is a complex and interdisciplinary field of research involving chemists, physicists, engineers, and materials scientists. Causal knowledge extraction from the literature is demonstrated using NLP.

Thermal plasmas, with temperatures up to and even exceeding 10 4 K, are capable of producing high density vapor phase precursors for the deposition of relatively thick films. Although this technology is still in its infancy, it will fill the void between the relatively slow deposition processes such as physical vapor deposition and the high rate thermal spray deposition processes. In this chapter, the present state-of-the-art of this field is reviewed with emphasis on the various types of reactors proposed for this emerging technology. Only applications which attracted particular attention, namely diamond and high T c superconducting film deposition, are discussed in greater detail. (orig.)

In this episode it is also narrated that the Chief Minister, Kicaka, would like to have her as his wife. However, the Chief Minister, Kicaka, was killed by Bima, who was disguised as Ballawa, meaning that the love story came to an end. From the language point of view, the episode telling that the Pandawas were in Wirata was transformed into Geguritan Kicaka written in the Balinese language. In addition, although the text was dynamically translated, many Old Javanese words are still used in the Balinese version.Similarly, geguritan Sarpayajaya adopted the episode of Sarpayajnya of Adiparwa; however, the plot was modified again using thestrophes pangkur, dangdanggula, sinom and durma and was introduced using the Balinese language. It is narrated that King Parikesit was bitten and killed by a snake named Taksaka. Consequently, his son, Janamejaya, performed a ritual known as Sarpayajaya, causing all the snakes to die. From the cultural point of view, the text is recited as part of the performing art and the art of music ‘magegitan’ in Bali. The text Sarpayajayaisrecited as part of the cremation ceremony ‘ngaben’ known as mamutru.

The use of a written assessment checklist for the provision of emergency contraception via community pharmacies: a simulated patient study

Directory of Open Access Journals (Sweden)

Schneider CR

2013-09-01

Full Text Available Background: The Pharmaceutical Society of Australia recommends use of a written assessment checklist prior to supply of emergency contraception by pharmacists. Objective: The aim of this research was to determine the prevalence of use of a written assessment checklist by community pharmacists and secondly, to ascertain the effect of the checklist on appropriate assessment and supply.Methods: Three female simulated patients visited 100 randomly selected pharmacies requesting supply of ‘the morning after pill’. Information provided when assessed by the pharmacist was that she had missed one inactive pill of her regular hormonal contraception. The amount of assessment provided and the appropriateness of supply were used as comparative outcome measures.Results: Eighty-three pharmacies used a written assessment checklist. Twenty-four of the pharmacies visited provided the appropriate outcome of non-supply. Pharmacies that used a written assessment checklist provided a greater quantity and consistency of assessment (11.3 ±2.5 v. 6.5 ±3.8 questions, p<0.0001 but this did not result in an improved frequency of an appropriate outcome (20%, n=16 v. 23%, n=3. Conclusions: While a written patient assessment checklist improved the quantity and consistency of patient assessment, it did not improve the advice provided by community pharmacies when handling requests for emergency contraception.

Gemstone deposits of Serbia

Full Text Available Gemstone minerals in Serbia have never been regarded as an interesting and significant resource. Nevertheless, more than 150 deposits and occurrences have been recorded and some of them preliminarily explored in the last 50 years. The majority of deposits and occurrences are located within the Serbo-Macedonian metallogenic province and the most significant metallogenic units at the existing level of knowledge are the Fruska Gora ore district, Cer ore district, Sumadija metallogenic zone, Kopaonik metallogenic zone and Lece-Halkidiki metallogenic zone. The most important genetic type of deposits is hydrothermal, particularly in case of serpentinite/peridotite as host/parent rock. Placer deposits are also economically important. The dominant gemstones are silica minerals: chalcedony (Chrysoprase, carnelian, bluish chalcedony etc., jasper (picture, landscape, red etc., common opal (dendritic, green, milky white etc., silica masses (undivided, and quartz (rock crystal, amethyst etc.. Beside silica minerals significant gemstones in Serbia include also beryl (aquamarine, garnet (almandine and pyrope, tourmaline, fluorite, rhodochrosite, carbonate-silica breccia, carbonate-silica onyx, silicified wood, howlite, serpentinite, marble onyx, and kyanite. This paper aims to present an overview of Serbian gemstone deposits and occurrences and their position based on a simplified gemstone metallogenic map of Serbia, as well as genetic-industrial classification of gemstone deposits and gemstone varieties.

Uranium deposits in Africa

Wilpolt, R.H.; Simov, S.D.

1979-01-01

Africa is not only known for its spectacular diamond, gold, copper, chromium, platinum and phosphorus deposits but also for its uranium deposits. At least two uranium provinces can be distinguished - the southern, with the equatorial sub-province; and the south Saharan province. Uranium deposits are distributed either in cratons or in mobile belts, the first of sandstone and quartz-pebble conglomerate type, while those located in mobile belts are predominantly of vein and similar (disseminated) type. Uranium deposits occur within Precambrian rocks or in younger platform sediments, but close to the exposed Precambrian basement. The Proterozoic host rocks consist of sediments, metamorphics or granitoids. In contrast to Phanerozoic continental uranium-bearing sediments, those in the Precambrian are in marginal marine facies but they do contain organic material. The geology of Africa is briefly reviewed with the emphasis on those features which might control the distribution of uranium. The evolution of the African Platform is considered as a progressive reduction of its craton area which has been affected by three major Precambrian tectonic events. A short survey on the geology of known uranium deposits is made. However, some deposits and occurrences for which little published material is available are treated in more detail. (author)

Experimental measurements of the thermal conductivity of ash deposits: Part 2. Effects of sintering and deposit microstructure

Energy Technology Data Exchange (ETDEWEB)

A. L. Robinson; S. G. Buckley; N. Yang; L. L. Baxter

2000-04-01

The authors report results from an experimental study that examines the influence of sintering and microstructure on ash deposit thermal conductivity. The measurements are made using a technique developed to make in situ, time-resolved measurements of the effective thermal conductivity of ash deposits formed under conditions that closely replicate those found in the convective pass of a commercial boiler. The technique is designed to minimize the disturbance of the natural deposit microstructure. The initial stages of sintering and densification are accompanied by an increase in deposit thermal conductivity. Subsequent sintering continues to densify the deposit, but has little effect on deposit thermal conductivity. SEM analyses indicates that sintering creates a layered deposit structure with a relatively unsintered innermost layer. They hypothesize that this unsintered layer largely determines the overall deposit thermal conductivity. A theoretical model that treats a deposit as a two-layered material predicts the observed trends in thermal conductivity.

To what extent can intracrater layered deposits that lack clear sedimentary textures be used to infer depositional environments?

Cadieux, Sarah B.; Kah, Linda C.

Craters within Arabia Terra, Mars, contain hundreds of meters of layered strata showing systematic alternation between slope- and cliff-forming units, suggesting either rhythmic deposition of distinct lithologies or similar lithologies that experienced differential cementation. On Earth, rhythmically deposited strata can be examined in terms of stratal packaging, wherein the interplay of tectonics, sediment deposition, and base level (i.e., the position above which sediment accumulation is expected to be temporary) result in changes in the amount of space available for sediment accumulation. These predictable patterns of sediment deposition can be used to infer changes in basin accommodation regardless of the mechanism of deposition (e.g. fluvial, lacustrine, or aeolian). Here, we analyze sedimentary deposits from three craters (Becquerel Crater, Danielson Crater, Crater A) in Arabia Terra. Each crater contains layered deposits that are clearly observed in orbital images. Although orbital images are insufficient to specifically determine the origin of sedimentary deposits, depositional couplets can be interpreted in terms of potential accommodation space available for deposition, and changes in the distribution of couplet thickness through stratigraphy can be interpreted in terms of changing base level and the production of new accommodation space. Differences in stratal packaging in these three craters suggest varying relationships between sedimentary influx, sedimentary base level, and concomitant changes in accommodation space. Previous groundwater upwelling models hypothesize that layered sedimentary deposits were deposited under warm climate conditions of early Mars. Here, we use observed stacking patterns to propose a model for deposition under cold climate conditions, wherein episodic melting of ground ice could raise local base level, stabilize sediment deposition, and result in differential cementation of accumulated strata. Such analysis demonstrates that

Seasonal atmospheric deposition variations of polychlorinated biphenyls (PCBs) and comparison of some deposition sampling techniques.

Birgül, Askın; Tasdemir, Yücel

2011-03-01

Ambient air and bulk deposition samples were collected between June 2008 and June 2009. Eighty-three polychlorinated biphenyl (PCB) congeners were targeted in the samples. The average gas and particle PCB concentrations were found as 393 ± 278 and 70 ± 102 pg/m(3), respectively, and 85% of the atmospheric PCBs were in the gas phase. Bulk deposition samples were collected by using a sampler made of stainless steel. The average PCB bulk deposition flux value was determined as 6,020 ± 4,350 pg/m(2) day. The seasonal bulk deposition fluxes were not statistically different from each other, but the summer flux had higher values. Flux values differed depending on the precipitation levels. The average flux value in the rainy periods was 7,480 ± 4,080 pg/m(2) day while the average flux value in dry periods was 5,550 ± 4,420 pg/m(2) day. The obtained deposition values were lower than the reported values given for the urban and industrialized areas, yet close to the ones for the rural sites. The reported deposition values were also influenced by the type of the instruments used. The average dry deposition and total deposition velocity values calculated based on deposition and concentration values were found as 0.23 ± 0.21 and 0.13 ± 0.13 cm/s, respectively.

Geochronology of the Thompson Creek Mo Deposit: Evidence for the Formation of Arc-related Mo Deposits

Science.gov (United States)

Lawrence, C. D.; Coleman, D. S.; Stein, H. J.

2016-12-01

The Thompson Creek Mo deposit in central ID, has been categorized as an arc-related Mo deposit due to the location, grade of Mo, and relative lack of enrichments in F, Rb, and Nb, compared to the Climax-type Mo deposits. Geochronology from this arc-related deposit provides an opportunity to compare and contrast magmatism, and mineralization to that in Climax-type deposits. Distinct pulses of magmatism were required to form the Thompson Creek Mo deposit, which is consistent with recent geochronology from Climax-type deposits. Molybdenite Re-Os geochronology from five veins requires at least three pulses of magmatism and mineralization between 89.39 +/- 0.37 and 88.47 +/- 0.16 Ma. Zircon U-Pb ages from these mineralized samples overlap with molybdenite mineralization, but show a much wider range (91.01 +/- 0.37 to 87.27 +/- 0.69). Previous work from Climax-type Mo deposits suggest a correlation between a super eruption, and the subsequent rapid (<1 Ma) onset, and completion of Mo mineralizing intrusions. The longer life (3-4 Ma) for the Thompson Creek Mo deposit suggests that the mineralizing intrusions for arc-related Mo deposits may not need to have as high [Mo] as the Climax-type deposits. This study also finds a shift in the source of magmatism from the pre- to syn-mineralizing intrusions. Zircons from pre-mineralizing intrusions have much higher (15-60 pg) concentrations of radiogenic Pb than zircons from mineralized intrusions, which all have less than 15 pg, though whole rock [U] are similar.

Surficial uranium deposits: summary and conclusions

International Nuclear Information System (INIS)

Otton, J.K.

1984-01-01

Uranium occurs in a variety of surficial environments in calcretes, gypcretes, silcretes, dolocretes and in organic sediments. Groundwater moving on low gradients generates these formations and, under favourable circumstances, uranium deposits. A variety of geomorphic settings can be involved. Most surficial deposits are formed in desert, temperate wetland, tropical, or transitional environments. The largest deposits known are in sedimentary environments in arid lands. The deposits form largely by the interaction of ground or surface waters on the geomorphic surface in favourable geologic terrains and climates. The deposits are commonly in the condition of being formed or reconstituted, or being destroyed. Carnotite is common in desert deposits while in wetland deposits no uranium minerals may be seen. Radioactive disequilibrium is common, particularly in wetland deposits. Granites and related rocks are major source rocks and most large deposits are in regions with enriched uranium contents, i.e. significantly greater than 5 ppm uranium. Uranium dissolution and transport is usually under oxidizing conditions. Transport in desert conditions is usually as a bicarbonate. A variety of fixation mechanisms operate to extract the uranium and form the deposits. Physical barriers to groundwater flow may initiate ore deposition. Mining costs are likely to be low because of the near surface occurrence, but there may be processing difficulties as clay may be present and the saline or carbonate content may be high. (author)

The directed energy deposition process has been mainly applied to re-work and the restoration of damaged steel. Differences in material properties between the base and the newly deposited materials are unavoidable, which may affect the mechanical properties and durability of the part. We investigated the effect of heat treatment on the characteristics of tool steel deposited by the DED process. We prepared general tool steel materials of H13 and D2 that were deposited onto heat-treated substrates of H13 and D2, respectively, using a direct metal tooling process. The hardness and microstructure of the deposited steel before and after heat treatment were investigated. The hardness of the deposited H13 steel was higher than that of wrought H13 steel substrate, while that of the deposited D2 was lower than that of wrought D2. The evolution of the microstructures by deposition and heat treatment varied depending on the materials. In particular, the microstructure of the deposited D2 steel after heat treatment consisted of fine carbides in tempered martensite and it is expected that the deposited D2 steel will have isotropic properties and high hardness after heat treatment.

The Effect of a Written and Pictorial Home Exercise Prescription on Adherence for People with Stroke

Directory of Open Access Journals (Sweden)

Sheetal Kara

2015-12-01

Conclusion: The addition of a written and pictorial home exercise prescription does not lead to better adherence to a home exercise programme compared to having no written and pictorial instructions. Possible reasons may be that patients had caregivers as a support system, and the exercise logbook served as a reminder and motivational track record for patients. There also does not appear to be a relationship between functional ability and level of adherence, which may be due to most of the study participants being within the optimal time frame for spontaneous functional recovery. Further study at different time frames in stroke rehabilitation in different contexts is recommended.

2001-01-01

Sequence stratigraphy has been widely used in hydrocarbon exploration and development, and great achievements have been achieved. However, its application to the prospecting for sandstone-type uranium deposits is just beginning. The metallogenic characteristics of sandstone-type uranium deposits and those of oil and gas are compared, and the relationship between sandstone-type uranium metallogenesis and the system tracts of sequence stratigraphy is studied. The authors propose that highest and system tracts are the main targets for prospecting interlayer oxidation zone type sandstone uranium deposits, and the incised valleys of low stand system tracts are favourable places for phreatic oxidation zone type sandstone uranium deposits, and transgressive system tracts are generally unfavorable to the formation of in-situ leachable sandstone-type uranium deposits. Finally, the authors look ahead the application potential of sequence stratigraphy to the prospecting for sandstone-type uranium deposits in continental depositional basins

Incremental comprehension of pitch relationships in written music: Evidence from eye movements.

Science.gov (United States)

Hadley, Lauren V; Sturt, Patrick; Eerola, Tuomas; Pickering, Martin J

2017-03-17

To investigate how proficient pianists comprehend pitch relationships in written music when they first encounter it we conducted two experiments in which proficient pianists' eyes were tracked while they read and played single-line melodies. In Experiment 1, participants played at their own speed; in Experiment 2 they played with an external metronome. The melodies were either congruent or anomalous, with the anomaly involving one bar being shifted in pitch to alter the implied harmonic structure (e.g., non-resolution of a dominant). In both experiments, anomaly led to rapid disruption in participants' eye-movements in terms of regressions from the target bar, indicating that pianists process written pitch relationships online. This is particularly striking because in musical sight-reading eye movement behaviour is constrained by the concurrent performance. Both experiments also showed that anomaly induced pupil dilation. Together these results indicate that proficient pianists rapidly integrate the music that they read into the prior context, and that anomalies in terms of pitch relationships lead to processing difficulty. These findings parallel those of text reading, suggesting that structural processing involves similar constraints across domains.

Transforming Biology Assessment with Machine Learning: Automated Scoring of Written Evolutionary Explanations

Nehm, Ross H.; Ha, Minsu; Mayfield, Elijah

2012-02-01

This study explored the use of machine learning to automatically evaluate the accuracy of students' written explanations of evolutionary change. Performance of the Summarization Integrated Development Environment (SIDE) program was compared to human expert scoring using a corpus of 2,260 evolutionary explanations written by 565 undergraduate students in response to two different evolution instruments (the EGALT-F and EGALT-P) that contained prompts that differed in various surface features (such as species and traits). We tested human-SIDE scoring correspondence under a series of different training and testing conditions, using Kappa inter-rater agreement values of greater than 0.80 as a performance benchmark. In addition, we examined the effects of response length on scoring success; that is, whether SIDE scoring models functioned with comparable success on short and long responses. We found that SIDE performance was most effective when scoring models were built and tested at the individual item level and that performance degraded when suites of items or entire instruments were used to build and test scoring models. Overall, SIDE was found to be a powerful and cost-effective tool for assessing student knowledge and performance in a complex science domain.

Booth, Shawn; Hui, Joe; Alojado, Zoraida; Lam, Vicky; Cheung, William; Zeller, Dirk; Steyn, Douw; Pauly, Daniel

2013-10-15

We present a global dioxin model that simulates one year of atmospheric emissions, transport processes, and depositions to the earth's terrestrial and marine habitats. We map starting emission levels for each land area, and we also map the resulting deposits to terrestrial and marine environments. This model confirms that 'hot spots' of deposition are likely to be in northern Europe, eastern North America, and in parts of Asia with the highest marine dioxin depositions being the northeast and northwest Atlantic, western Pacific, northern Indian Ocean and the Mediterranean. It also reveals that approximately 40% of airborne dioxin emissions are deposited to marine environments and that many countries in Africa receive more dioxin than they produce, which results in these countries being disproportionately impacted. Since human exposure to dioxin is largely through diet, this work highlights food producing areas that receive higher atmospheric deposits of dioxin than others. Copyright © 2013 Elsevier Ltd.

Depositional environment of the San Miguel lignite deposit in Atascosa and McMullen Counties, Texas

Energy Technology Data Exchange (ETDEWEB)

Gowan, S.W.

1985-01-01

An analysis of the environment of deposition of the San Miguel lignite deposit was carried out in order to understand newly discovered characteristics of the deposit. The environment of deposition of the overburden and underburden was evaluated through an interpretation of three continuous cores. Four coal cores and a highwall section were carefully described to determine the depositional environmental of the coal seams and partings. These studies were supplemented by the construction of seam and parting isopachs, and the analysis of the distribution of sulfur isotopes, sulfur, forms, and total sulfur within the coal. The sedimentary package is composed of a basal prograding barrier that beach, dune, and back-barrier sands. This unit correlates with a downdip sand that was also interpreted as a prograding barrier by other authors. The barrier is overlain by a series of slit and clay deposits of lagoonal, tidal flat, and tidal channel origin. These deposits are capped by restricted lagoon sediments composed of green, calcareous clays that occasionally contain shell layers. The restricted lagoon deposits formed when the barrier closed the lagoon off from the sea. Peat forming freshwater swamps eventually became established behind the barrier and on top of the restricted lagoon sediments. The parting isopachs reveal a reticulate morphology similar to the mangrove swamps located lateral to the modern Niger River Delta. The partings represent vegetated tidal flat deposits that formed during periodic invasions by the sea that killed the swamp and inundated the peat with sulfate rich water. The lignite interval is capped by open lagoon and tidal flat sediments.

Vertically aligned carbon nanotube growth by pulsed laser deposition and thermal chemical vapor deposition methods

International Nuclear Information System (INIS)

Sohn, Jung Inn; Nam, Chunghee; Lee, Seonghoon

2002-01-01

We have grown vertically aligned carbon nanotubes on the various substrates such as a planar p-type Si(1 0 0) wafer, porous Si wafer, SiO 2 , Si 3 N 4 , Al 2 O 3 , and Cr by thermal chemical vapor deposition (CVD) at 800 deg.C, using C 2 H 2 gas as a carbon source and Fe catalyst films deposited by a pulsed laser on the substrates. The Fe films were deposited for 5 min by pulsed laser deposition (PLD). The advantage of Fe deposition by PLD over other deposition methods lies in the superior adhesion of Fe to a Si substrate due to high kinetic energies of the generated Fe species. Scanning electron microscopy (SEM) images show that vertically well-aligned carbon nanotubes are grown on Fe nanoparticles formed from the thermal annealing of the Fe film deposited by PLD on the various substrates. Atomic force microscopy (AFM) images show that the Fe film annealed at 800 deg.C is broken to Fe nanoparticles of 10-50 nm in size. We show that the appropriate density of Fe nanoparticles formed from the thermal annealing of the film deposited by PLD is crucial in growing vertically aligned carbon nanotubes. Using a PLD and a lift-off method, we developed the selective growth of carbon nanotubes on a patterned Fe-coated Si substrate

Understanding the spectrum of diesel injector deposits

Quigley, Robert; Barbour, Robert [Lubrizol Limited, Derby (United Kingdom); Arters, David; Bush, Jim [Lubrizol Corporation, Wickliffe, OH (United States)

2013-06-01

Understanding the origin of diesel fuel injector deposits used to be relatively simple; for the most part they were caused by the decomposition of fuel during the combustion process, were generally organic in nature and typically only affected the nozzle orifices. However, modem fuel injector designs appear to be both more severe in terms of generating conditions conducive to creating new and different types of deposits and more likely to have their operation affected by those deposits. Changes to fuel composition and type have in some cases increased the potential pool of reactive species or provided new potential deposit precursors. As a result, the universe of diesel injector deposits now range from the traditional organic to partially or fully inorganic in nature and from nozzle coking deposits to deposits which can seize the internal components of the injector; so called internal diesel injector deposits. Frequently, combinations of inorganic and organic deposits are found. While power loss is one well known issue associated with nozzle deposits, other field problems resulting from these new deposits include severe issues with drivability, emissions, fuel consumption and even engine failure. Conventional deposit control additive chemistries were developed to be effective against organic nozzle coking deposits. These conventional additives in many cases may prove ineffective against this wide range of deposit types. This paper discusses the range of deposits that have been found to adversely impact modem diesel fuel injectors and compares the performance of conventional and new, advanced deposit control additives against these various challenges to proper fuel injector functioning.

Tailor, Jiten P.; Khimani, Ankurkumar J.; Chaki, Sunil H.

2018-05-01

The crystal structure, Raman spectroscopy and surface microtopography study on as-deposited CuS thin films were carried out. Thin films deposited by two techniques of solution growth were studied. The thin films used in the present study were deposited by chemical bath deposition (CBD) and dip coating deposition techniques. The X-ray diffraction (XRD) analysis of both the as-deposited thin films showed that both the films possess covellite phase of CuS and hexagonal unit cell structure. The determined lattice parameters of both the films are in agreement with the standard JCPDS as well as reported data. The crystallite size determined by Scherrer's equation and Hall-Williamsons relation using XRD data for both the as-deposited thin films showed that the respective values were in agreement with each other. The ambient Raman spectroscopy of both the as-deposited thin films showed major emission peaks at 474 cm-1 and a minor emmision peaks at 265 cm-1. The observed Raman peaks matched with the covellite phase of CuS. The atomic force microscopy of both the as-deposited thin films surfaces showed dip coating thin film to be less rough compared to CBD deposited thin film. All the obtained results are presented and deliberated in details.

Full Text Available Writing is to transfer the visualised ideas on the paper. Writing, one of the language skills, is a significant tool of communication which provides the permanency of information conveying emotions and thoughts. Since writing has both cognitive and physical aspects, it makes writing the hardest and the latest language skill to improve. The studies show that writing activity is the most difficult skill students have difficulty. In higher education, in order to improve writing skills of students and give basic information and skills about writing skills written expression, composition and writing education lessons are taught both in the department of Turkish Language and Literature and in the departments of Turkish Language in the Faculties of Education. One of the aims of these lessons is to teach students written expression techniques together with the purposes and practices. One of the written expression techniques is text completion skill that improves student’s creativity and enhances her/his imaginary world.

2017-06-01

Full Text Available Mastering English, as foreign language need a lot of time since it is a continuing process. English foreign language of young learners, however, can’t be mastered by memorizing. The young learners should have strategy, which can be used as the direction of the classroom activites to help the students enhancing of language skill, specially in writting. There were the problem to be solved in this study, namely the students have difficult to construct the written text. The strategies which were used in the learning process were boring. Hence, the researcher tried to solve students’ difficulty in written text through Transition Action Detail Strategy. This study focused on two variables. The independent variable was Transition Action Detail Strategy, meanwhile dependent variable was written text. The researcher used true experimental design which consist of control group and experimental group. The subject of this research was students of young learner at the eight grade of English Course at Payakumbuh. The result revealed that Transition Action Detail Strategy was a good strategy that can influence the students’ narrative text. By using df.70, the writer not found it in the table. Because 70 was higher than 60 and smaller than 120. Then, the results from interpolation by using df.70, it could be known that the critical value of   t-table for the 5% level was 1.990, the critical value of t-table for the 1% level was 2.638. From these all the data analysis, it can be seen that t-observed (4.763 was higher than t-table (5% =1.990, 1% = 2.638. The data confirm that t-observed  is higher than t-table, therefore it can be inferred that Ha is accepted and Ho is rejected. It means that there is significant influence of applying Transition Action Detail Strategy on Wwritten Text of Young learners.   Key words: Transition Action Detail Strategy, Young Learners, English Foreign Language, English  Course.

Readability of the written study information in pediatric research in France.

Directory of Open Access Journals (Sweden)

Véronique Ménoni

Full Text Available BACKGROUND: The aim was to evaluate the readability of research information leaflets (RIL for minors asked to participate in biomedical research studies and to assess the factors influencing this readability. METHODS AND FINDINGS: All the pediatric protocols from three French pediatric clinical research units were included (N = 104. Three criteria were used to evaluate readability: length of the text, Flesch's readability score and presence of illustrations. We compared the readability of RIL to texts specifically written for children (school textbooks, school exams or extracts from literary works. We assessed the effect of protocol characteristics on readability. The RIL had a median length of 608 words [350 words, 25(th percentile; 1005 words, 75(th percentile], corresponding to two pages. The readability of the RIL, with a median Flesch score of 40 [30; 47], was much poorer than that of pediatric reference texts, with a Flesch score of 67 [60; 73]. A small proportion of RIL (13/91; 14% were illustrated. The RIL were longer (p<0.001, more readable (p<0.001 and more likely to be illustrated (p<0.009 for industrial than for institutional sponsors. CONCLUSION: Researchers should routinely compute the reading ease of study information sheets and make greater efforts to improve the readability of written documents for potential participants.

Aerosol Deposition in Health and Disease

Science.gov (United States)

2012-01-01

Abstract The success of inhalation therapy is not only dependent upon the pharmacology of the drugs being inhaled but also upon the site and extent of deposition in the respiratory tract. This article reviews the main mechanisms affecting the transport and deposition of inhaled aerosol in the human lung. Aerosol deposition in both the healthy and diseased lung is described mainly based on the results of human studies using nonimaging techniques. This is followed by a discussion of the effect of flow regime on aerosol deposition. Finally, the link between therapeutic effects of inhaled drugs and their deposition pattern is briefly addressed. Data show that total lung deposition is a poor predictor of clinical outcome, and that regional deposition needs to be assessed to predict therapeutic effectiveness. Indeed, spatial distribution of deposited particles and, as a consequence, drug efficiency is strongly affected by particle size. Large particles (>6 μm) tend to mainly deposit in the upper airway, limiting the amount of drugs that can be delivered to the lung. Small particles (<2 μm) deposit mainly in the alveolar region and are probably the most apt to act systemically, whereas the particle in the size range 2–6 μm are be best suited to treat the central and small airways.

Mathematical Model of Transfer and Deposition of Finely Dispersed Particles in a Turbulent Flow of Emulsions and Suspensions

Science.gov (United States)

Laptev, A. G.; Basharov, M. M.

2018-05-01

The problem of modeling turbulent transfer of finely dispersed particles in liquids has been considered. An approach is used where the transport of particles is represented in the form of a variety of the diffusion process with the coefficient of turbulent transfer to the wall. Differential equations of transfer are written for different cases, and a solution of the cell model is obtained for calculating the efficiency of separation in a channel. Based on the theory of turbulent transfer of particles and of the boundary layer model, an expression has been obtained for calculating the rate of turbulent deposition of finely dispersed particles. The application of this expression in determining the efficiency of physical coagulation of emulsions in different channels and on the surface of chaotic packings is shown.

Electrostatic Deposition of Large-Surface Graphene

Directory of Open Access Journals (Sweden)

Charles Trudeau

2018-01-01

Full Text Available This work describes a method for electrostatic deposition of graphene over a large area using controlled electrostatic exfoliation from a Highly Ordered Pyrolytic Graphite (HOPG block. Deposition over 130 × 130 µm2 with 96% coverage is achieved, which contrasts with sporadic micro-scale depositions of graphene with little control from previous works on electrostatic deposition. The deposition results are studied by Raman micro-spectroscopy and hyperspectral analysis using large fields of view to allow for the characterization of the whole deposition area. Results confirm that laser pre-patterning of the HOPG block prior to cleaving generates anchor points favoring a more homogeneous and defect-free HOPG surface, yielding larger and more uniform graphene depositions. We also demonstrate that a second patterning of the HOPG block just before exfoliation can yield features with precisely controlled geometries.

Influence of deposition parameters on morphological properties of biomedical calcium phosphate coatings prepared using electrostatic spray deposition

International Nuclear Information System (INIS)

Leeuwenburgh, S.C.G.; Wolke, J.G.C.; Schoonman, J.; Jansen, J.A.

2005-01-01

In order to deposit biomedical calcium phosphate (CaP) coatings with a defined surface morphology, the electrostatic spray deposition (ESD) technique was used since this technique offers the possibility to deposit ceramic coatings with a variety of surface morphologies. A scanning electron microscopical study was performed in order to investigate the influence of several deposition parameters on the final morphology of the deposited coatings. The chemical characteristics of the coatings were studied by means of X-ray diffraction and Fourier-transform infrared spectroscopy. Regarding the chemical coating properties, the results showed that the coatings can be described as crystalline carbonate apatite coatings, a crystal phase which is similar to the mineral phase of bone and teeth. The morphology of CaP coatings, deposited using the ESD technique, was strongly dependent on the deposition parameters. By changing the nozzle-to-substrate distance, the precursor liquid flow rate and the deposition temperature, coating morphologies were deposited, which varied from dense to highly porous, reticular morphologies. The formation of various morphologies was the result of an equilibrium between the relative rates of CaP solute precipitation/reaction, solvent evaporation and droplet spreading onto the substrate surface

Micromorphology of modern tills in southwestern Spitsbergen – insights into depositional and post-depositional processes

Directory of Open Access Journals (Sweden)

Skolasińska Katarzyna

2016-12-01

Full Text Available Textural properties and microstructures are commonly used properties in the analysis of Pleistocene and older glacial deposits. However, contemporary glacial deposits are seldom studied, particularly in the context of post-depositional changes. This paper presents the results of a micromorphological study of recently deposited tills in the marginal zones of Hansbreen and Torellbreen, glaciers in southwestern Spitsbergen. The main objectives of this study were to compare modern tills deposited in subglacial and supraglacial conditions, as well as tills that were freshly released from ice with those laid down several decades ago. The investigated tills are primarily composed of large clasts of metamorphic rocks and represent coarse-grained, matrix-supported diamictons. The tills reveal several characteristic features for ductile (e.g. turbate structures and brittle (e.g. lineations, microshears deformations, which have been considered to be indicative of subglacial conditions. In supraglacial tills, the same structures are common as in the subglacial deposits, which points to the preservation of the primary features, though the sediment was transferred up to the glacier surface due to basal ice layer deformation and redeposited as slumps, or to formation of similar structures due to short-distance sediment re-deposition by mass flows. This study revealed that it might not be possible to distinguish subglacial and supraglacial tills on the basis of micromorphology if the latter are derived from a subglacial position. The only noted difference was the presence of iron oxide cementation zones and carbonate dissolution features in supraglacial tills. These features were found in tills that were deposited at least a few years ago and are interpreted to be induced by early post-depositional processes involving porewater/sediment interactions.

2017-05-01

Femtosecond Infrared (fs-IR) laser written fiber Bragg gratings (FBGs), have demonstrated great potential for extreme sensing. Such conditions are inherent to advanced power plant technologies and gas turbine engines, under development to reduce greenhouse gas emissions; and the ability to measure temperature gradients in these harsh environments is currently limited by the lack of sensors and controls capable of withstanding the high temperature, pressure and corrosive conditions present. This paper reviews our fabrication and deployment of hundreds of fs-IR written FBGs, for monitoring temperature gradients of an oxy-fuel fluidized bed combustor and an aerospace gas turbine combustor simulator.

Time Resolved Deposition Measurements in NSTX

2004-01-01

Time-resolved measurements of deposition in current tokamaks are crucial to gain a predictive understanding of deposition with a view to mitigating tritium retention and deposition on diagnostic mirrors expected in next-step devices. Two quartz crystal microbalances have been installed on NSTX at a location 0.77m outside the last closed flux surface. This configuration mimics a typical diagnostic window or mirror. The deposits were analyzed ex-situ and found to be dominantly carbon, oxygen, and deuterium. A rear facing quartz crystal recorded deposition of lower sticking probability molecules at 10% of the rate of the front facing one. Time resolved measurements over a 4-week period with 497 discharges, recorded 29.2 (micro)g/cm 2 of deposition, however surprisingly, 15.9 (micro)g/cm 2 of material loss occurred at 7 discharges. The net deposited mass of 13.3 (micro)g/cm 2 matched the mass of 13.5 (micro)g/cm 2 measured independently by ion beam analysis. Monte Carlo modeling suggests that transient processes are likely to dominate the deposition

Ksapabutr, Bussarin; Chalermkiti, Tanapol; Wongkasemjit, Sujitra; Panapoy, Manop

2013-01-01

This paper describes a simple and low-temperature approach to fabrication of dense and crack-free gadolinium doped ceria (GDC) thin films with controllable deposition by a magnetic-field-assisted electrostatic spray deposition technique. The influences of external permanent magnets on the deposition of GDC films were investigated. The coating area deposited using two magnets with the same pole arrangement decreased in comparison with the case of no magnets, whereas the largest deposition area was obtained in the system of the opposite poles. Analysis of as-deposited films at 450 °C indicated the formation of uniform, smooth and dense thin films with a single-phase fluorite structure. The films produced in the system using same poles were thicker, smaller in crystallite size and smoother than those fabricated under other conditions. Additionally, the GDC film deposited using the same pole arrangement showed the maximum in electrical conductivity of about 2.5 × 10 −2 S/cm at a low operating temperature of 500 °C. - Highlights: • Magnetic-field-assisted electrostatic spray allows a controllable coating. • Dense, crack-free thin films were obtained at low process temperature of 450 °C. • Control of deposition, thickness and uniformity is easy to achieve simultaneously. • Films from the same pole were thicker, smaller in crystal size and smoother. • The maximum conductivity of doped ceria film was 2.5 × 10 −2 S/cm at 500 °C

Factors influencing chloride deposition in a coastal hilly area and application to chloride deposition mapping

Directory of Open Access Journals (Sweden)

H. Guan

2010-05-01

Full Text Available Chloride is commonly used as an environmental tracer for studying water flow and solute transport in the environment. It is especially useful for estimating groundwater recharge based on the commonly used chloride mass balance (CMB method. Strong spatial variability in chloride deposition in coastal areas is one difficulty encountered in appropriately applying the method. A high-resolution bulk chloride deposition map in the coastal region is thus needed. The aim of this study is to construct a chloride deposition map in the Mount Lofty Ranges (MLR, a coastal hilly area of approximately 9000 km² spatial extent in South Australia. We examined geographic (related to coastal distance, orographic, and atmospheric factors that may influence chloride deposition, using partial correlation and regression analyses. The results indicate that coastal distance, elevation, as well as terrain aspect and slope, appear to be significant factors controlling chloride deposition in the study area. Coastal distance accounts for 70% of spatial variability in bulk chloride deposition, with elevation, terrain aspect and slope an additional 15%. The results are incorporated into a de-trended residual kriging model (ASOADeK to produce a 1 km×1 km resolution bulk chloride deposition and concentration maps. The average uncertainty of the deposition map is about 20–30% in the western MLR, and 40–50% in the eastern MLR. The maps will form a useful basis for examining catchment chloride balance for the CMB application in the study area.

Legal Deposit of Electronic Publications

Directory of Open Access Journals (Sweden)

Burcu Umut Zan

2009-06-01

Full Text Available The most important and basic role of the deposition studies, which are the greatest contributions to the knowledge sharing, is to gather the artistic and philosophical works of a country and provide them for the use of future researchers. However, since early deposition studies were limited with printed publications, they do not involve the electronic publication types appearing with the development of information technology. This stems from the fact that the electronic publications require procedures different from those of the printed publications in terms of deposition steps because of their structures. Today, in order to guarantee that all registered cultural products, which are mostly produced and used in the electronic environment could be fully collected, electronic publications should also be covered by and regulated under legal deposit. This study analyzes the deposition of electronic publications, within the framework of their storage and protection, being put in the use of the users as well as the common approaches to deposition practices in the world parallel to the developments in the information technology. The related situation in Turkey was also evaluated.

A radon progeny deposition model

2010-01-01

The next generation low-background detectors operating underground aim for unprecedented low levels of radioactive backgrounds. Although the radioactive decays of airborne radon (particularly 222 Rn) and its subsequent progeny present in an experiment are potential backgrounds, also problematic is the deposition of radon progeny on detector materials. Exposure to radon at any stage of assembly of an experiment can result in surface contamination by progeny supported by the long half life (22 y) of 210 Pb on sensitive locations of a detector. An understanding of the potential surface contamination from deposition will enable requirements of radon-reduced air and clean room environments for the assembly of low background experiments. It is known that there are a number of environmental factors that govern the deposition of progeny onto surfaces. However, existing models have not explored the impact of some environmental factors important for low background experiments. A test stand has been constructed to deposit radon progeny on various surfaces under a controlled environment in order to develop a deposition model. Results from this test stand and the resulting deposition model are presented.

Felsic magmatism and uranium deposits

International Nuclear Information System (INIS)

Cuney, M.

2014-01-01

Uranium strongly incompatible behaviour in silicate magmas results in its concentration in the most felsic melts and a prevalence of granites and rhyolites as primary U sources for the formation of U deposits. Despite its incompatible behaviour, U deposits resulting directly from magmatic processes are quite rare. In most deposits, U is mobilized by hydrothermal fluids or ground water well after the emplacement of the igneous rocks. Of the broad range of granite types, only a few have have U contents and physico-chemical properties that permit the crystallization of accessory minerals from which uranium can be leached for the formation of U deposits. The first granites on Earth which crystallized uraninite appeared at 3.1 Ga, are the potassic granites from the Kaapval craton (South Africa) which were also the source of the detrital uraninite for the Dominion Reef and Witwatersrand quartz pebble conglomerate deposits. Four types of granites or rhyolites can be sufficiently enriched in U to represent a significant source for the genesis of U deposits: peralkaline, high-K metaluminous calc-alkaline, L-type peraluminous ones and anatectic pegmatoids. L-type peraluminous plutonic rocks in which U is dominantly hosted in uraninite or in the glass in their volcanic equivalents represent the best U source. Peralkaline granites or syenites represent the only magmatic U-deposits formed by extreme fractional crystallization. The refractory character of the U-bearing minerals does not permit their extraction at the present economic conditions and make them unfavourable U sources for other deposit types. By contrast, felsic peralkaline volcanic rocks, in which U is dominantly hosted in the glassy matrix, represent an excellent source for many deposit types. High-K calc-alkaline plutonic rocks only represent a significant U source when the U-bearing accessory minerals [U-thorite, allanite, Nb oxides] become metamict. The volcanic rocks of the same geochemistry may be also a

Full Text Available Abstract Background Lectures remain an important teaching method to present and structure knowledge to many students concurrently. Adequate measures are necessary to maintain the quality of the lectures. The aim of this study was to determine the impact on the lecture quality using written structured feedback and to compare the ratings of surgical lectures between students and surgical peers. Methods Prospective analysis of two consecutive surgical lecture series for undergraduate students at Goethe-University Medical School was performed before and after evaluation of the lecturers via independent written feedback from trained undergraduate students and surgeons. The 22-item feedback instrument covered three areas of performance: content, visualization, and delivery. Additional suggestions for improvement were provided from both students and surgical peers who anonymously attended the lectures. The lecturers, experienced surgeons, as well as the student and peer raters were blinded in terms of the aim and content of the study. Their response to the feedback was collected using a web-based 13-item questionnaire. The Kendall’s-W coefficient was computed to calculate inter-rater reliability (IRR. Differences between ratings before and after feedback were analyzed using Student’s t-test for dependent samples. The Kolmogorov-Smirnov-test was used for independent samples. Results A total of 22 lectures from a possible 32 given by 13 lecturers were included and analyzed by at least three surgeons and two students. There were significant improvements in overall score as well as in the details of 9 of the 13 items were found. The average inter-rater reliability was 0.71. There were no differences in the ratings as a function of the rater’s level of expertise (peers vs. students. We found that 13/23 lecturers (56.5% answered the questionnaire, and 92% strongly agreed that the written feedback was useful. 76.9% of the lecturers revised their lecture

Particle deposition in ventilation ducts

Energy Technology Data Exchange (ETDEWEB)

Sippola, Mark Raymond [Univ. of California, Berkeley, CA (United States)

2002-09-01

Exposure to airborne particles is detrimental to human health and indoor exposures dominate total exposures for most people. The accidental or intentional release of aerosolized chemical and biological agents within or near a building can lead to exposures of building occupants to hazardous agents and costly building remediation. Particle deposition in heating, ventilation and air-conditioning (HVAC) systems may significantly influence exposures to particles indoors, diminish HVAC performance and lead to secondary pollutant release within buildings. This dissertation advances the understanding of particle behavior in HVAC systems and the fates of indoor particles by means of experiments and modeling. Laboratory experiments were conducted to quantify particle deposition rates in horizontal ventilation ducts using real HVAC materials. Particle deposition experiments were conducted in steel and internally insulated ducts at air speeds typically found in ventilation ducts, 2-9 m/s. Behaviors of monodisperse particles with diameters in the size range 1-16 μm were investigated. Deposition rates were measured in straight ducts with a fully developed turbulent flow profile, straight ducts with a developing turbulent flow profile, in duct bends and at S-connector pieces located at duct junctions. In straight ducts with fully developed turbulence, experiments showed deposition rates to be highest at duct floors, intermediate at duct walls, and lowest at duct ceilings. Deposition rates to a given surface increased with an increase in particle size or air speed. Deposition was much higher in internally insulated ducts than in uninsulated steel ducts. In most cases, deposition in straight ducts with developing turbulence, in duct bends and at S-connectors at duct junctions was higher than in straight ducts with fully developed turbulence. Measured deposition rates were generally higher than predicted by published models. A model incorporating empirical equations based on the

Electronic properties of p-GaAs deposited on n-Si with pulsed-laser deposition

International Nuclear Information System (INIS)

Ullrich, B; Erlacher, A; Smith, H E; Mitchel, W C; Brown, G J

2008-01-01

By means of nanosecond laser pulses at 355, 532, and 1064 nm, p(Zn)-type GaAs was ablated and deposited on n-type Si. The samples showed rectification and Hall measurements established that the deposited material was p-type, but the active-doping concentration was six orders of magnitude below the target value. Because secondary-ion mass spectroscopy results indicated stoichiometric material transfer, we concluded that most of the Zn atoms do not act as acceptors because of the amorphous film texture. The work further showed indications that pulsed-laser deposition at 355 nm causes enhanced Si diffusion into the deposited film, compared to the ablations done at 532 and 1064 nm

Thermomagnetically written domains in TbFeCo thin films

International Nuclear Information System (INIS)

Reim, W.; Weller, D.

1988-01-01

Characteristic features of thermomagnetically written domains in amorphous Tb x (Fe 90 Co 10 ) 100-x alloy thin films having different magnetic properties are reported. In particular, the writing process in materials with low Tb content chi ≤ 21 dominated by the demagnetizing field is compared to the bias field dominated process in Tb rich samples 22 ≤ chi ≤ 25. Domain wall movement over lateral dimensions of the bit size is found for Tb poor materials while for chi ≥ 22 domain boundaries are primarily determined by the area heated up to the Curie-temperature. The importance of mechanical stress on domain formation and irreversible changes of the storage medium due to overheating in the writing process are reported

Comparison of stress in single and multiple layer depositions of plasma-deposited amorphous silicon dioxide

International Nuclear Information System (INIS)

Au, V; Charles, C; Boswell, R W

2006-01-01

The stress in a single-layer continuous deposition of amorphous silicon dioxide (SiO 2 ) film is compared with the stress within multiple-layer intermittent or 'stop-start' depositions. The films were deposited by helicon activated reactive evaporation (plasma assisted deposition with electron beam evaporation source) to a 1 μm total film thickness. The relationships for stress as a function of film thickness for single, two, four and eight layer depositions have been obtained by employing the substrate curvature technique on a post-deposition etch-back of the SiO 2 film. At film thicknesses of less than 300 nm, the stress-thickness relationships clearly show an increase in stress in the multiple-layer samples compared with the relationship for the single-layer film. By comparison, there is little variation in the film stress between the samples when it is measured at 1 μm film thickness. Localized variations in stress were not observed in the regions where the 'stop-start' depositions occurred. The experimental results are interpreted as a possible indication of the presence of unstable, strained Si-O-Si bonds in the amorphous SiO 2 film. It is proposed that the subsequent introduction of a 'stop-start' deposition process places additional strain on these bonds to affect the film structure. The experimental stress-thickness relationships were reproduced independently by assuming a linear relationship between the measured bow and film thickness. The constants of the linear model are interpreted as an indication of the density of the amorphous film structure

Uraniferous surficial deposits in Southern Africa

International Nuclear Information System (INIS)

Hambleton-Jones, B.B.; Levin, M.; Wagener, G.F.

1986-01-01

Surficial uranium deposits are located in the north-western Cape Province of South Africa, in the Namib Desert east of Walvis Bay in South West Africa/Namibia and in the Serule Block of Botswana. They have been classified into the valley-fill, lacustrine, and pedogenic types. Carnotite is the main uranium-bearing mineral in the larger surficial deposits, with other minerals such as soddyite and phosphuranylite occurring locally. Uraninite or urano-organic complexes occur in the reducing environments of the diatomaceous earth, peat-rich deposits. Economically, the valley-fill type is the most important, with the largest deposits occurring in South West Africa/Namibia. In South West Africa/Namibia the valley-fill surficial uranium deposits occur in the Tumas and Langer Heinrich formations of the Teriary to Recent Namib Group. The Tubas, Langer Heinrich, and Welwitchia deposits are discussed: in them, carnotite occurs in calcareous and gypsiferous fluvial gravels. The pedogenic deposit at Mile 72 occurs in weathered granite and overlying gypcrete and has little economic potential. The economic potential of the surficial deposits in the north-western Cape Province is very limited in comparison with their South West African/Namibian counterparts, but the most important deposits are the lacustrine type, in particular those containing peat and diatomaceous earth. The mechanisms for the precipitation and preservation of the uranium are discussed

Hideout in steam generator tube deposits

Balakrishnan, P.V.; Franklin, K.J.; Turner, C.W.

1998-05-01

Hideout in deposits on steam generator tubes was studied using tubes coated with magnetite. Hideout from sodium chloride solutions at 279 degrees C was followed using an on-line high-temperature conductivity probe, as well as by chemical analysis of solution samples from the autoclave in which the studies were done. Significant hideout was observed only at a heat flux greater than 200 kW/m 2 , corresponding to a temperature drop greater than 2 degrees C across the deposits. The concentration factor resulting from the hideout increased highly non-linearly with the heat flux (varying as high as the fourth power of the heat flux). The decrease in the apparent concentration factor with increasing deposit thickness suggested that the pores in the deposit were occupied by a mixture of steam and water, which is consistent with the conclusion from the thermal conductivity measurements on deposits in a separate study. Analyses of the deposits after the hideout tests showed no evidence of any hidden-out solute species, probably due to the concentrations being very near the detection limits and to their escape from the deposit as the tests were being ended. This study showed that hideout in deposits may concentrate solutes in the steam generator bulk water by a factor as high as 2 x 10 3 . Corrosion was evident under the deposit in some tests, with some chromium enrichment on the surface of the tube. Chromium enrichment usually indicates an acidic environment, but the mobility required of chromium to become incorporated into the thick magnetite deposit may indicate corrosion under an alkaline environment. An alkaline environment could result from preferential accumulation of sodium in the solution in the deposit during the hideout process. (author)

Negative body image has a significant impact on self-esteem, disordered eating, and general health. Writing about distressing events and experiences has been found to have beneficial effects on psychological and physical health outcomes. This study investigated whether a written self-disclosure intervention, compared to a writing about body image success stories (WSS) intervention, had beneficial effects on self-esteem and body image. One hundred and fifty-eight women (aged 18-22 years) were allocated to either: written emotional disclosure (WED); WSS; or a control, non-emotional writing condition. All measures were completed at baseline and at follow-up 4 weeks later. A condition by time interaction was observed for implicit self-esteem, such that levels of self-esteem were improved 4 weeks later in the WED condition. Implicit self-esteem was also found to be greater following WED compared to the control condition, but not following WSS. This is the first study to demonstrate that WED has beneficial effects on implicit outcome measures such as self-esteem indicating that the positive effects of expressive writing may initially operate by influencing automatically activated attitudes towards the self. The impact of WED on implicit self-esteem may have implications for future health. ©2010 The British Psychological Society.

2010-12-01

The aim of this study was to better understand the utility of using the Parents' Evaluation of Developmental Status (PEDS) in well-child visits by analyzing themes and patterns in parents' written responses on the PEDS form. We reviewed a consecutive sample of medical records with PEDS forms for children aged 6 months to 9 years (site 1) and 3 to 5 years (site 2). We recorded the concerns that parents identified in response to the 10 PEDS questions along with demographic information. We then categorized parents' written comments about those concerns according to comment content. We used qualitative and quantitative methods for analysis. We collected 752 PEDS forms. Ninety percent of the parents endorsed at least 1 concern (94.6% on the English forms versus 69.7% on the Spanish forms; P Parents qualified 27.5% of their concerns with a written comment. In 23.9% of cases in which parents identified a concern and provided a written comment, the content of the comment did not match the question's intent; rates of mismatch were similar for the English and Spanish forms. Among comments regarding behavioral concerns, 12% reflected a misunderstanding of age-appropriate behavior. Medical concerns accounted for 14.1% of the comments; these concerns were more common on English forms (61.3%) than on Spanish forms (1.7%) (P Parents frequently used the PEDS forms to communicate additional concerns regarding their child or provide positive feedback on their child's progress. The inappropriate developmental expectations, limited health literacy, and culturally distinct comments on the PEDS forms reinforce the importance of using screening tools to enhance the care provided during visits but not to replace patient-provider communication.

The effect of fog on radionuclide deposition velocities

International Nuclear Information System (INIS)

Gibb, R.; Carson, P.; Thompson, W.

1997-01-01

Current nuclear power station release models do not evaluate deposition under foggy atmospheric conditions. Deposition velocities and scavenging coefficients of radioactive particles entrained in fog are presented for the Point Lepreau area of the Bay of Fundy coast. It is recommended to calculate deposition based on fog deposition velocities. The deposition velocities can be calculated from common meteorological data. The range of deposition velocities is approximately 1 - 100 cm/s. Fog deposition is surface roughness dependent with forests having larger deposition and deposition velocities than soil or grasses.

Batch, Yamen; Yusof, Maryati Mohd; Noah, Shahrul Azman

2013-02-27

Medical blogs have emerged as new media, extending to a wider range of medical audiences, including health professionals and patients to share health-related information. However, extraction of quality health-related information from medical blogs is challenging primarily because these blogs lack systematic methods to organize their posts. Medical blogs can be categorized according to their author into (1) physician-written blogs, (2) nurse-written blogs, and (3) patient-written blogs. This study focuses on how to organize physician-written blog posts that discuss disease-related issues and how to extract quality information from these posts. The goal of this study was to create and implement a prototype for a Web-based system, called ICDTag, based on a hybrid taxonomy-folksonomy approach that follows a combination of a taxonomy classification schemes and user-generated tags to organize physician-written blog posts and extract information from these posts. First, the design specifications for the Web-based system were identified. This system included two modules: (1) a blogging module that was implemented as one or more blogs, and (2) an aggregator module that aggregated posts from different blogs into an aggregator website. We then developed a prototype for this system in which the blogging module included two blogs, the cardiology blog and the gastroenterology blog. To analyze the usage patterns of the prototype, we conducted an experiment with data provided by cardiologists and gastroenterologists. Next, we conducted two evaluation types: (1) an evaluation of the ICDTag blog, in which the browsing functionalities of the blogging module were evaluated from the end-user's perspective using an online questionnaire, and (2) an evaluation of information quality, in which the quality of the content on the aggregator website was assessed from the perspective of medical experts using an emailed questionnaire. Participants of this experiment included 23 cardiologists and

The security analyzer: A security analyzer program written in Prolog

International Nuclear Information System (INIS)

Zimmerman, B.D.; Densley, P.J.

1986-09-01

The Security Analyzer is a software tool capable of analyzing the effectiveness of a facility's security system. It is written in the Prolog logic programming computer language, using entity-relationship data modeling techniques. The program performs the following functions: (1) provides descriptive, locational and operational status information about intrusion detectors and assessment devices (i.e., ''sensors'' and ''cameras'') upon request; (2) provides for storage and retrieval of maintenance history information for various components of the security system (including intrusion detectors), and allows for changing that information as desired; (3) provides a ''search'' mode, wherein all paths are found from any specified physical location to another specified location which satisfy user chosen ''intruder detection'' probability and elapsed time criteria (i.e., the program finds the ''weakest paths'' from a security point of view). The first two of these functions can be provided fairly easily with a conventional database program; the third function could be provided using Fortran or some similar language, though with substantial difficulty. In the Security Analyzer program, all these functions are provided in a simple and straight-forward manner. This simplicity is possible because the program is written in the symbolic (as opposed to numeric) processing language Prolog, and because the knowledge base is structured according to entity-relationship modeling principles. Also, the use of Prolog and the entity-relationship modeling technique allows the capabilities of the Security analyzer program, both for knowledge base interrogation and for searching-type operations, to be easily expanded in ways that would be very difficult for a numeric and more algorithmically deterministic language such as Fortran to duplicate. 4 refs

Influence of the deposition geometry on the microstructure of sputter-deposited V-Al-C-N coatings

Multi-element hard coating materials such as V-Al-C-N are of great interest for many technological applications. Their mechanical properties depend on the composition and microstructure of the coating. In order to determine the optimum composition and deposition conditions of these complex materials, many samples are required. One powerful tool for reducing the number of experiments is based on the so-called combinatorial approach for thin film deposition: many different thin film samples can be realized simultaneously, exploiting the deposition gradient resulting from codeposition of several materials. We will present an X-ray diffraction study of the influence of the deposition geometry on the microstructure of V-Al-C-N coatings. The films were deposited by reactive RF magnetron sputtering from a segmented target composed of AlN and VC. Synchrotron radiation measurements where performed at the beamline PDIFF at ANKA. Significant texture changes were observed which can be attributed to the deposition geometry, as verified by calculations of the flux distribution. We conclude that codeposition can accelerate significantly the screening of new materials, under the condition that the desired property is not significantly influenced by the microstructural changes due to the deposition geometry.

A Positivity Bias in Written and Spoken English and Its Moderation by Personality and Gender.

Science.gov (United States)

Augustine, Adam A; Mehl, Matthias R; Larsen, Randy J

2011-09-01

The human tendency to use positive words ("adorable") more often than negative words ("dreadful") is called the linguistic positivity bias. We find evidence for this bias in two studies of word use, one based on written corpora and another based on naturalistic speech samples. In addition, we demonstrate that the positivity bias applies to nouns and verbs as well as adjectives. We also show that it is found to the same degree in written as well as spoken English. Moreover, personality traits and gender moderate the effect, such that persons high on extraversion and agreeableness and women display a larger positivity bias in naturalistic speech. Results are discussed in terms of how the linguistic positivity bias may serve as a mechanism for social facilitation. People, in general, and some people more than others, tend to talk about the brighter side of life.

2017-10-31

A method of electroless atomic layer deposition is described. The method electrolessly generates a layer of sacrificial material on a surface of a first material. The method adds doses of a solution of a second material to the substrate. The method performs a galvanic exchange reaction to oxidize away the layer of the sacrificial material and deposit a layer of the second material on the surface of the first material. The method can be repeated for a plurality of iterations in order to deposit a desired thickness of the second material on the surface of the first material.

Felsic magmatism and uranium deposits

International Nuclear Information System (INIS)

Cuney, Michel

2014-01-01

The strongly incompatible behaviour of uranium in silicate magmas results in its concentration in the most felsic melts and a prevalence of granites and rhyolites as primary U sources for the formation of U deposits. Despite its incompatible behavior, U deposits resulting directly from magmatic processes are quite rare. In most deposits, U is mobilized by hydrothermal fluids or ground water well after the emplacement of the igneous rocks. Of the broad range of granite types, only a few have U contents and physico-chemical properties that permit the crystallization of accessory minerals from which uranium can be leached for the formation of U deposits. The first granites on Earth, which crystallized uraninite, dated at 3.1 Ga, are the potassic granites from the Kaapval craton (South Africa) which were also the source of the detrital uraninite for the Dominion Reef and Witwatersrand quartz pebble conglomerate deposits. Four types of granites or rhyolites can be sufficiently enriched in U to represent a significant source for the genesis of U deposits: per-alkaline, high-K met-aluminous calc-alkaline, L-type peraluminous and anatectic pegmatoids. L-type peraluminous plutonic rocks in which U is dominantly hosted in uraninite or in the glass of their volcanic equivalents represent the best U source. Per-alkaline granites or syenites are associated with the only magmatic U-deposits formed by extreme fractional crystallization. The refractory character of the U-bearing minerals does not permit their extraction under the present economic conditions and make them unfavorable U sources for other deposit types. By contrast, felsic per-alkaline volcanic rocks, in which U is dominantly hosted in the glassy matrix, represent an excellent source for many deposit types. High-K calc-alkaline plutonic rocks only represent a significant U source when the U-bearing accessory minerals (U-thorite, allanite, Nb oxides) become metamict. The volcanic rocks of the same geochemistry may be

Vein-type uranium deposits

International Nuclear Information System (INIS)

Rich, R.A.; Holland, H.D.; Petersen, U.

1975-01-01

A critical review is presented of published data bearing on the mineralogy, paragenesis, geochemistry, and origin of veiw-type uranium deposits. Its aim is to serve as a starting point for new research and as a basis for the development of new exploration strategies. During the formation of both vein and sandstone types of deposits uranium seems to have been dissolved by and transported in rather oxidized solutions, and deposited where these solutions encountered reducing agents such as carbon, sulfides, ferrous minerals and hydrocarbons. Granitic rocks abnormally enriched in uranium have apparently been the most common source for uranium in vein-type deposits. Oxidizing solutions have been derived either from the surface or from depth. Surface solutions saturated with atmospheric oxygen have frequently passed through red bed or clean sandstone conduits on their way to and from uranium source rocks. Deep solutions of non-surface origin have apparently become sufficiently oxidizing by passage through and equilibration with red beds. The common association of clean sandstones or red beds with uranium-rich granites in the vicinity of vein-type uranium deposits is probably not fortuitous, and areas where these rock types are found together are considered particularly favorable targets for uranium exploration

Full Text Available Zn–Ni alloys electrochemically deposited on steel under various deposition conditions were investigated. The alloys were deposited on a rotating disc electrode and on a steel panel from chloride solutions by direct and reverse current. The influence of reverse plating variables (cathodic and anodic current densities and their time duration on the composition, phase structure and corrosion properties were investigated. The chemical content and phase composition affect the anticorrosive properties of Zn–Ni alloys during exposure to a corrosive agent (3 % NaCl solution. It was shown that the Zn–Ni alloy electrodeposited by reverse current with a full period T = 1 s and r = 0.2 exhibits the best corrosion properties of all the investigated alloys deposited by reverse current.

Lamônica, Dionísia Aparecida Cusin; Ribeiro, Camila da Costa; Ferraz, Plínio Marcos Duarte Pinto; Tabaquim, Maria de Lourdes Merighi

Moyamoya disease is an unusual form of occlusive, cerebrovascular disorder that affects the arteries of the central nervous system, causing acquired language alterations and learning difficulties. The study aim was to describe the oral/written language and cognitive skills in a seven-year-and-seven-month-old girl diagnosed with Moyamoya disease. The assessment consisted of interviews with her parents and application of the following instruments: Observation of Communicative Behavior, Peabody Picture Vocabulary Test, Academic Performance Test, Profile of Phonological Awareness, Raven's Progressive Matrices Test, Special Scale, Wechsler Intelligence Scale for Children, Bender Visual Motor Gestalt Test, and Wisconsin Card Sorting Test. Two episodes of stroke in the left and right temporal-parietal and left frontal areas occurred until the age of six years and five months. Revascularization surgery and medication treatment were conducted. The audiologic and ophthalmologic assessments indicated normality. At the time of the study, the girl was attending the second grade of elementary school. She presented changes in oral and written language (syllabic-alphabetic), non-naming of all graphemes, low arithmetic and writing means, reading skill below first grade level and psycholinguistic delay, and pre-school level phonological processing skills. The psychological evaluation indicated satisfactory intellectual level; however, it also showed cognitive performance impairment in verbal and execution tasks and limitations on graphic-perceptual-motor skills and sequential logic organization. The stroke episodes influenced the performance of learning processes, affecting the analysis, integration, and interpretation of relevant visual and auditory information.

Effects of deposition period on the chemical bath deposited Cu4SnS4 thin films

International Nuclear Information System (INIS)

Kassim, Anuar; Wee Tee, Tan; Soon Min, Ho.; Nagalingam, Saravanan

2010-01-01

Cu 4 SnS 4 thin films were prepared by simple chemical bath deposition technique. The influence of deposition period on the structural, morphological and optical properties of films was studied. The films were characterized using X-ray diffraction, atomic force microscopy and UV-Vis Spectrophotometer. X-ray diffraction patterns indicated that the films were polycrystalline with prominent peak attributed to (221) plane of orthorhombic crystal structure. The films prepared at 80 min showed significant increased in the intensity of all diffractions. According to AFM images, these films indicated that the surface of substrate was covered completely. The obtained films also produced higher absorption characteristics when compared to the films prepared at other deposition periods based on optical absorption studies. The band gap values of films deposited at different deposition periods were in the range of 1.6-2.1 eV. Deposition for 80 min was found to be the optimum condition to produce good quality thin films under the current conditions. (author).

Surface deposition from radioactive plumes

Accidents involving nuclear plants may release radioactive particles and gases to the atmosphere. Dry deposition of particles has been investigated mainly in the laboratory and a general understanding of the transfer mechanisms has been established. However there is apparently a substantial discrepancy between the few field observations of dry deposition of particles and laboratory measurements, particularly for 0.1 - 1 μm particles for which laboratory work shows very small deposition rates. In addition there are few estimates of deposition rates for forest and some other kinds of terrain. The most important gas in the context of a nuclear accident is I-131 and the behaviour of this gas at grass surfaces has received much attention. However smaller quantities of other gases and vapours may be released and the surface absorption of these species may require further investigation. In addition there is little knowledge of the behaviour of gases over many types of surface. The rate of deposition of particles and gases is influenced by many parameters including wind speed and the temperature stratification of the lower atmosphere. Conditions which give poor atmospheric dispersion usually give lower deposition velocities. Transfer to man depends on the availability of deposited materials on crops and grass. A wide range of isotopes including iodine and several metallic fission products are lost with a half life for residence on grass ranging from a few days to a few tens days, depending on climatic conditions

Data are presented from a monitoring network of 18 bulk precipitation collectors and one wet-only collector in the urban area of Greater Manchester, in the north west of England. Weekly samples were analysed for all the major ions in precipitation along with gaseous nitrogen dioxide concentrations from diffusion tubes. Statistical analysis of the data shows significant spatial variation of non marine sulphate, nitrate, ammonium, acidity and calcium concentrations, and nitrogen dioxide concentrations. Calcium is thought to be responsible for the buffering of acidity and is of local origin. Wet deposition is the likely removal process for calcium in the atmosphere and probably by below cloud scavenging. Nitrate and ammonium concentrations and depositions show close spatial, temporal and statistical association. Examination of high simultaneous episodes of nitrate and ammonium deposition shows that these depositions cannot be explained in terms of trajectories and it is suggested that UK emissions of ammonia may be important. Statistical analysis of the relationships between nitrate and ammonium depositions, concentrations and precipitation amount suggest that ammonia from mesoscale sources reacts reversibly with nitric acid aerosol and is removed by below cloud scavenging. High episodes of the deposition of non marine sulphate are difficult to explain by trajectory analysis alone, perhaps suggesting local sources. In a comparison between wet deposition and bulk deposition, it was shown that only 15.2% of the non marine sulphur was dry deposited to the bulk precipitation collector. 63 refs., 86 figs., 31 tabs.

Inputs of acidifying compounds to terrestrial ecosystems include deposition of the gases NO 2 , NO, HNO 2 , HNO 3 , NH 3 and SO 2 and the ions NO 3- , NH 4+ , SO 4 2- and H + in precipitation, cloud droplets and particles. Recent research has identified particular ecosystems and regions in which terrestrial effects are closely linked with specific deposition processes. This review paper identifies areas in which important developments have occurred during the last five years and attempts to show which aspects of the subject are most important for policy makers. Amongst the conclusions drawn, the authors advise that current uncertainties in estimates of S and N inputs by dry deposition should be incorporated in critical load calculations, and that, in regions dominated by wet deposition, spatial resolution of total inputs should be improved to match the current scales of information on landscape sensitivity to acidic inputs. 44 refs., 9 figs

Carbonaceous deposits on naptha reforming catalysts

Carbonaceous deposits on naphtha reforming catalysts play a decisive role in limiting process performance. The deposits negatively after catalyst activity, selectivity and the production cycle of a semi regenerative reformer. The magnitude of negative effect of those deposits is directly proportional to their amounts and complexity. Investigations on used reforming catalysts samples reveal that the amount and type (complexity of the chemical nature) of carbonaceous deposits are directly proportional to the catalysts life on stream and the severity of operating conditions. In addition, the combustibility behavior of carbonaceous deposits on the catalyst samples taken from different reformers are found to be different. Optimal carbon removal, for in situ catalyst regeneration, requires the specific conditions be developed, based on the results of well designed and properly performed investigations of the amount and type of carbonaceous deposits.

Full Text Available Manganese sulfide thin films were chemically deposited from an aqueous solution containing manganese sulfate, sodium thiosulfate and sodium tartrate. The influence of deposition time (2, 3, 6 and 8 days on the properties of thin films was investigated. The structure and surface morphology of the thin films were studied by X-ray diffraction and atomic force microscopy, respectively. In addition, in order to investigate the optical properties of the thin films, the UV-visible spectrophotometry was used. The XRD results indicated that the deposited MnS2 thin films exhibited a polycrystalline cubic structure. The number of MnS2 peaks on the XRD patterns initially increased from three to six peaks and then decreased to five peaks, as the deposition time was increased from 2 to 8 days. From the AFM measurements, the film thickness and surface roughness were found to be dependent on the deposition time.

A stable and tunable single-longitudinal-mode (SLM) Brillouin/Erbium fiber laser (BEFL) with narrow linewidth is proposed and experimentally demonstrated. A uniform Bragg grating written in a segment of unpumped Erbium-doped fiber (EDF) is incorporated as an auto-tracking filter to achieve SLM operation. A length of 5 m pumped EDF is used to provide both Brillouin and linear gain in the cavity. The linewidth is measured to be 18 kHz and the lasing peak power fluctuation and wavelength shift are monitored less than 0.027 dB and 2 pm respectively.

Pulsed laser deposition (PLD) is one of the well-established physical vapor deposition methods used for synthesis of ultra-thin layers. Especially PLD is suitable for the preparation of thin films of complex alloys and ceramics where the conservation of the stoichiometry is critical. Beside several advantages of PLD, inhomogeneity in thickness limits use of PLD in some applications. There are several approaches such as rotation of the substrate or scanning of the laser beam over the target to achieve homogenous layers. On the other hand movement and transition create further complexity in process parameters. Here we present a new approach which we call Matrix Shaped PLD to control the thickness and homogeneity of deposited layers precisely. This new approach is based on shaping of the incoming laser beam by a microlens array and a Fourier lens. The beam is split into much smaller multi-beam array over the target and this leads to a homogenous plasma formation. The uniform intensity distribution over the target yields a very uniform deposit on the substrate. This approach is used to deposit carbide and oxide thin films for biomedical applications. As a case study coating of a stent which has a complex geometry is presented briefly.
