Full Text Available Recently, virtual reality (VR and augmented reality (AR have received increasing attention, with the development of VR/AR devices such as head-mounted displays, haptic devices, and AR glasses. Medicine is considered to be one of the most effective applications of VR/AR. In this article, we describe a systematic literature review conducted to investigate the state-of-the-art VR/AR technology relevant to plastic surgery. The 35 studies that were ultimately selected were categorized into 3 representative topics: VR/AR-based preoperative planning, navigation, and training. In addition, future trends of VR/AR technology associated with plastic surgery and related fields are discussed.

In the basic material and spiritual civilization highly abundant today, people in the United States to explore the origin of the hearts, but also the beautiful things combined with the general law. People start from the perspective of the theory and methods to explore and reflect the value of the arts, but also more pioneer artists to join the activities. Marxist literary theory is now a mature theoretical system of Marxist literary theory and discussion of specialized and not a complete discussion, but scattered in various chapters of his book. Marxist literary theory is the nature of literature, characteristics of the basic methods and principles, laws and social action. We must be content and form of literary works into the whole production process and the complex social relationships matter to go, in a dynamic social relations be investigated, in order to grasp the real laws and principles of literature and criticism.

Transcendence through Illumination: Marginalized Identity Re-valued as Art and Literature

Full Text Available provide a critical analysis of the female identity of E. Luminata, written by Chilean writer, Diamela Eltit. This essay will examine how E. Luminata fits into the world of autobiographical feminism, with ties to multiculturalism, and world literature. Her series of artistic scenes in the town square allow her to challenge standardized notions of beauty’s ephemerality and permanence. Within the text, E. Luminata uses her art to protest Pinochet’s military government during the 1980’s. E. Luminata actively uses art, aesthetics, and her sexualized identity to create an argument against the “grotesque” nature of the military regime. As such, her artistic protests, read within a piece of translated literature, help readers to define the nature of the aesthetic experience of womanhood and contemplate personal agency, desire, and cultural possessiveness. Her identity is manifested through the contradictory binary of the natural and the artificial, since she presents herself as a spectacle, for others to perceive. By doing so, she deconstructs her own objectification within the novel.

Verbal Dreamscapes. Dorothea Tanning’s Visual Literature

Glăvan Gabriela

2016-12-01

Full Text Available A Surrealist painter whose artistic vision is equally visible in her literary works, Dorothea Tanning established a solid dialogue between literature and the plastic arts. The corpus of her literary oeuvre is rather small, consisting of a novel, a volume of poetry and her memoir, Between Lives. This paper argues that Tanning can be regarded as an exemplary author of a creative transfer between verbal and plastic imagination. It also explores the tension between the two means of expression, most visible in her novel Chasm: A Weekend. Here, the imagery and enigmatic symbolism of her painting come to life in the story of a strange little girl called Destina Meridian.

Montemurro, Paolo; Porcnik, Ales; Hedén, Per; Otte, Maximilian

2015-04-01

Patients interested in aesthetic plastic surgery procedures increasingly seek advice on social media and rely on easily accessible online information. The investigatory goal was to determine the impact of this phenomenon on the everyday aesthetic plastic surgery practice. Five hundred consecutive patients completed a questionnaire prior to their consultation with a plastic surgeon at our clinic. A questionnaire was also completed by 128 plastic surgeons practising in 19 different countries. A literature review was performed. Almost all patients (95%) used the internet to collect information prior to consultation, for 68% of them it being their first search method. Social media were used by 46% of patients and 40% of these were strongly influenced when choosing a specific doctor. The majority of plastic surgeons (85%) thought the information found on social media could lead to unrealistic expectations. However, 45% of plastic surgeons believed that their consultations became easier after the advent of social media, 29% found them more difficult. A literature review showed a high percentage of poor quality internet websites regarding plastic surgery and an increase in use of social media among plastic surgeons. The internet and social media play an important and growing role in plastic surgery. This results in more informed patients but may create unrealistic expectations. Even if the internet provides ample information, it cannot replace the face-to-face consultation, which always should remain a detailed process, covering both risks and limitations of alternative procedures. Available literature on how social media influences the medical practice is still scarce and further research is needed. This journal requires that authors assign a level of evidence to each article.

Creative Arts Therapies as Temporary Home for Refugees: Insights from Literature and Practice

Directory of Open Access Journals (Sweden)

Rebekka Dieterich-Hartwell

2017-10-01

Full Text Available One of the frequently overlooked psychosocial problems of refugees is the phenomenon of homesickness. Being forced into exile and unable to return home may cause natural feelings of nostalgia but may also result in emotional, cognitive, behavioral and physical adversities. According to the literature, the creative arts therapies with their attention to preverbal language—music, imagery, dance, role play, and movement—are able to reach individuals through the senses and promote successive integration, which can lead to transformation and therapeutic change. These forms of therapy can be a temporary home for refugees in the acculturation process, by serving as a safe and enactive transitional space. More specifically, working with dance and movement can foster the experience of the body as a home and thus provide a safe starting place, from which to regulate arousal, increase interoception, and symbolize trauma- and resource-related processes. Hearing, playing, and singing music from the home culture may assist individuals in maintaining their cultural and personal individuality. Creating drawings, paintings, or sculpturing around the topics of houses and environments from the past can help refugees to retain their identity through art, creating safe spaces for the future helps to look ahead, retain resources, and regain control. This article provides a literature review related to home and homesickness, and the role the arts therapies can play for refugees in transition. It further reports selected interview data on adverse life events and burdens in the host country from a German study. We propose that the creative arts therapies are not only a container that offers a temporary home, but can also serve as a bridge that gently guides refugees to a stepwise integration in the host country. Several clinical and research examples are presented suggesting that the support and affirmation through the creative arts can strengthen individuals in

Compendium of information on identification and testing of materials for plastic solar thermal collectors

McGinniss, V.D.; Sliemers, F.A.; Landstrom, D.K.; Talbert, S.G.

1980-07-31

This report is intended to organize and summarize prior and current literature concerning the weathering, aging, durability, degradation, and testing methodologies as applied to materials for plastic solar thermal collectors. Topics covered include (1) rate of aging of polymeric materials; (2) environmental factors affecting performance; (3) evaluation and prediction of service life; (4) measurement of physical and chemical properties; (5) discussion of evaluation techniques and specific instrumentation; (6) degradation reactions and mechanisms; (7) weathering of specific polymeric materials; and (8) exposure testing methodology. Major emphasis has been placed on defining the current state of the art in plastics degradation and on identifying information that can be utilized in applying appropriate and effective aging tests for use in projecting service life of plastic solar thermal collectors. This information will also be of value where polymeric components are utilized in the construction of conventional solar collectors or any application where plastic degradation and weathering are prime factors in material selection.

Full Text Available This paper presents a research into the portrait genre from the axiological perspective and its redefi nition in cinematography. In each of the art domains, there is a way to render the physical aspect and the interior world of any individual from diff erent perspectives – literal portrait, painted portrait, carved portrait and portrait in photography. Th e defi ning aspects of these portraits, which are created through the masters` artistic imagination, infl uenced directly or indirectly the creation and development of the portrait in cinematography. The portrait in cinematography is getting “mature” in the branches of art and is easily combining the experiences gained throughout history. Th e fi lm-portrait itself shows the audience a diff erent form of art. It is obvious that we cannot diminish the value of portraits from other branches of art. However, cinematography has its advantages, of which the main one is that it combines all elements in one body: the image, the word and music.

The purpose of this study is to determine and characterize the scientific and nonscientific factors that influence the rate of article citation in the field of plastic surgery. Cross-sectional study. We reviewed all entries in Annals of Plastic Surgery and Journal of Plastic, Reconstructive, and Aesthetic Surgery from January 1, 2007 to December 31, 2007; and Plastic and Reconstructive Surgery from January 1, 2007 to December 31, 2008. All scientific articles were analyzed and several article characteristics were extracted. The number of citations at 5 years was collected as the outcome variable. A multivariable analysis was performed to determine which variables were associated with higher citations rates. A total of 2456 articles were identified of which only 908 fulfilled the inclusion criteria. Most studies were publications in the fields of reconstructive (26.3%) or pediatric/craniofacial (17.6%) surgery. The median number of citations 5 years from publication was 8. In the multivariable analysis, factors associated with higher citations rates were subspecialty field (p = 0.0003), disclosed conflict of interest (p = 0.04), number of authors (p = 0.04), and journal (p = 0.02). We have found that higher level of evidence (or other study methodology factors) is not associated with higher citation rates. Instead, conflict of interest, subspecialty topic, journal, and number of authors are strong predictors of high citation rates in plastic surgery.

Wilson, Ceri; Bungay, Hilary; Munn-Giddings, Carol; Boyce, Melanie

2016-04-01

Internationally there is growing interest in the use of the arts in the healthcare context evidenced by the number of research studies reported in the nursing and medical literature. Establishing successful projects in healthcare environments will to some extent be reliant on the cooperation of staff working in these settings: healthcare professionals and their cultural values will be the lynchpin in the relationship between the artists organising the activities and the patients. This review appraises healthcare professionals' perceptions of the value of the arts in healthcare settings, and the impact of the arts on healthcare professionals. A critical review of the literature between 2004 and 2014 was undertaken. The following databases were searched: MedLine, CINAHL, AMED, Web of Science and ASSIA. Searches included words from three categories: arts activities; healthcare settings, and healthcare providers. Studies were included if they were written in English, explored the attitudes of healthcare professionals on the use of the arts in healthcare settings or the impact of arts activities on healthcare staff. Studies conducted in community venues and/or reporting on arts therapies (art, drama or music) were excluded. An initial 52 studies were identified and following screening for relevance and quality 27 articles were reviewed. Arts interventions were diverse and included music listening, visual arts, reading and creative writing, and dance. Despite some methodological limitations of the reviewed studies it was found that the majority of staff believed that engaging in arts interventions has a positive impact on patients' health and well-being. The findings suggest that arts interventions are perceived to have an impact on patients' stress, mood, pain levels, and sleep. Furthermore, staff believed that the arts can enhance communication between staff and patients, helping to build rapport and strengthen interactions. The majority of reported staff outcomes were

Plastic flexible films waste management - A state of art review.

Horodytska, O; Valdés, F J; Fullana, A

2018-04-21

Plastic flexible films are increasingly used in many applications due to their lightness and versatility. In 2014, the amount of plastic films represented 34% of total plastic packaging produced in UK. The flexible film waste generation rises according to the increase in number of applications. Currently, in developed countries, about 50% of plastics in domestic waste are films. Moreover, about 615,000 tonnes of agricultural flexible waste are generated in the EU every year. A review of plastic films recycling has been conducted in order to detect the shortcomings and establish guidelines for future research. This paper reviews plastic films waste management technologies from two different sources: post-industrial and post-consumer. Clean and homogeneous post-industrial waste is recycled through closed-loop or open-loop mechanical processes. The main differences between these methods are the quality and the application of the recycled materials. Further research should be focused on closing the loops to obtain the highest environmental benefits of recycling. This could be accomplished through minimizing the material degradation during mechanical processes. Regarding post-consumer waste, flexible films from agricultural and packaging sectors have been assessed. The agricultural films and commercial and industrial flexible packaging are recycled through open-loop mechanical recycling due to existing selective waste collection routes. Nevertheless, the contamination from the use phase adversely affects the quality of recycled plastics. Therefore, upgrading of current washing lines is required. On the other hand, household flexible packaging shows the lowest recycling rates mainly because of inefficient sorting technologies. Delamination and compatibilization methods should be further developed to ensure the recycling of multilayer films. Finally, Life Cycle Assessment (LCA) studies on waste management have been reviewed. A lack of thorough LCA on plastic films waste

Full Text Available The Art Toys phenomenon, better known as Art Toy Movement, was born in China in the mid-nineties and quickly spread out to the rest of the world. The toys are an artistic production of serial sculpture, made by handcrafts or on an industrial scale. There are several types of toys, such as custom toys and canvas toys, synonyms of designer toys, although they are often defined according to the constituent material, such as vinyl toys (plastic and plush toys (fabric. Art toys are the heirs of an already pop-surrealist and neo-pop circuit, which since the eighties of the twentieth century has pervaded the Japanese-American art scene, winking to the playful spirit of the avant-garde of the early century. Some psychoanalytic, pedagogical and anthropological studies about “play theories”, may also help us to understand and identify these heterogeneous products as real works of art and not simply as collectible toys.

Plastic heat exchangers: a state-of-the-art review

Energy Technology Data Exchange (ETDEWEB)

Miller, D; Holtz, R E; Koopman, R N; Marciniak, T J; MacFarlane, D R

1979-07-01

Significant increases in energy utilization efficiency can be achieved through the recovery of low-temperature rejected heat. This energy conserving possibility provides incentive for the development of heat exchangers which could be employed in applications where conventional units cannot be used. Some unique anticorrosion and nonstick characteristics of plastics make this material very attractive for heat recovery where condensation, especially sulfuric acid, and fouling occur. Some of the unique characteristics of plastics led to the commercial success of DuPont's heat exchangers utilizing polytetrafluoroethylene (trade name Teflon) tubes. Attributes which were exploited in this application were the extreme chemical inertness of the material and its flexibility, which enabled utilization in odd-shaped spaces. The wide variety of polymeric materials available ensures chemical inertness for almost any application. Lower cost, compoundability with fillers to improve thermal/mechanical properties, and versatile fabrication methods are incentives for many uses. Also, since many plastics resist corrosion, they can be employed in lower temperature applications (< 436 K), where condensation can occur and metal units have been unable to function. It is clear that if application and design can be merged to produce a cost-effective alternate to present methods of handling low-temperature rejected heat, then there is significant incentive for plastic heat exchangers, to replace traditional metallic heat exchangers or to be used in services where metals are totally unsuited.

Tiihonen, Marianne; Brattico, Elvira; Maksimainen, Johanna; Wikgren, Jan; Saarikallio, Suvi

2017-01-01

The present literature review investigated how pleasure induced by music and visual-art has been conceptually understood in empirical research over the past 20 years. After an initial selection of abstracts from seven databases (keywords: pleasure, reward, enjoyment, and hedonic), twenty music and eleven visual-art papers were systematically compared. The following questions were addressed: (1) What is the role of the keyword in the research question? (2) Is pleasure considered a result of variation in the perceiver's internal or external attributes? (3) What are the most commonly employed methods and main variables in empirical settings? Based on these questions, our critical integrative analysis aimed to identify which themes and processes emerged as key features for conceptualizing art-induced pleasure. The results demonstrated great variance in how pleasure has been approached: In the music studies pleasure was often a clear object of investigation, whereas in the visual-art studies the term was often embedded into the context of an aesthetic experience, or used otherwise in a descriptive, indirect sense. Music studies often targeted different emotions, their intensity or anhedonia. Biographical and background variables and personality traits of the perceiver were often measured. Next to behavioral methods, a common method was brain imaging which often targeted the reward circuitry of the brain in response to music. Visual-art pleasure was also frequently addressed using brain imaging methods, but the research focused on sensory cortices rather than the reward circuit alone. Compared with music research, visual-art research investigated more frequently pleasure in relation to conscious, cognitive processing, where the variations of stimulus features and the changing of viewing modes were regarded as explanatory factors of the derived experience. Despite valence being frequently applied in both domains, we conclude, that in empirical music research pleasure

Cuestión de tiempo: Michael Fried y el tiempo del arte moderno A matter of time: Michael Fried and modernist art the time of modernist art

Directory of Open Access Journals (Sweden)

David Díaz Soto

2011-07-01

Full Text Available En el siglo XIX, autores fundacionales del formalismo, como Fiedler o Hildebrand, contrapusieron estrictamente las artes plásticas, «puramente visuales», a las artes verbales del discurso, proscribiéndoles la narración y disociándolas de la temporalidad: se trata del «principio de exclusión del tiempo», vinculado al formalismo. Más tarde, el crítico «modernista» de arte Clement Greenberg planteó la instantaneidad, en tanto que opuesta a la duración, como modalidad ideal de la experiencia artística. Pero el historiador y crítico de arte Michael Fried, en sus textos de los años 60 sobre arte abstracto, se distancia de Greenberg, desarrollando un discurso sobre la temporalidad en las artes plásticas, con nociones como «tiempo visual»; y en sus posteriores textos historiográficos investiga las modalidades temporales de la representación pictórica. La aparente paradoja entre la crítica de Fried a la hipóstasis «literalista» de la duración en las tardovanguardias y el papel crucial que concede a Manet y a la instantaneidad en el origen del arte moderno, la resolveremos atendiendo a su reivindicación de la temporalidad durativa de «lo cotidiano». Así cabe comprender la concepción de la modalidad temporal característica de la modernidad y del arte moderno, a la que apunta su noción teórica de presentness.In the nineteenth century, seminal authors of Formalism, like Fiedler or Hildebrand, strictly compared the «purely visual» plastic arts to the discursive arts of verbal language, ruling out narrativity from plastic arts, which they dissociated from temporality - the formalist «principle of exclusion of time». Later on, «modernist» art critic Clement Greenberg claimed that instantaneousness, as opposed to duration, was the ideal modality for artistic experience. Art critic and historian Michael Fried did not share Greenberg's position, but developed instead a discourse about time in plastic arts. In his early

Compared with music research, visual-art research investigated more frequently pleasure in relation to conscious, cognitive processing, where the variations of stimulus features and the changing of viewing modes were regarded as explanatory factors of the derived experience. Despite valence being frequently applied in both domains, we conclude, that in empirical music research pleasure

PORTRAIT IN LITERATURE AND GRAPHIC ART: THE CASE OF THE FIERY ANGEL

Directory of Open Access Journals (Sweden)

Natalia A. Drovaleva

2017-06-01

Full Text Available This essay analyzes portraits in several editions of The Fiery Angel published during This essay analyzes portraits in several editions of The Fiery Angel published during Bryusov’s lifetime and claims that the portrait was as a universal point of convergence for verbal and visual arts. The dialogue between literature and graphics in the context of the synthesis of arts sheds new light on the possibilities for interdisciplinary research. The time of the “beautiful book” was a time of great artists and illustrators who introduced the peculiarities of their own style and the manner of their artistic schools into their art. Books were commonly decorated with vignettes and famous paintings. Portraits, as well as plates in general, were of the highest quality. They were ornamental and illusory, with every minute detail finely drawn out. Yet, in the second edition of the novel Bryusov deliberately included medieval engravings and portraits. A comparative analysis of the verbal portraits in The Fiery Angel and engraved portraits in the book (Ruprecht, Heinrich, Faust, Mephistopheles, Renata, and Madiel demonstrates that both the main and the secondary characters of the novel are picturesque and multidimensional whereas the xylographic portraits rather reveal conventionality and simplicity of the medieval time. This way Bryusov was seeking to debase clichе’s, especially as regards Agrippa von Nettesheim and Faust: according to Bryusov, the character of Agrippa had already become a clichе’d image and so was the popular engraving of the scientist that he reproduced in the middle of the sixth chapter of the 1909 edition. Juxtaposing the verbal and the graphic portraits in The Fiery Angel helps us better understand the function of the verbal portrait in a Symbolist text that was determined by the author’s design, on the one hand, and by various “instruments” of different arts, on the other.

Biological network extraction from scientific literature: state of the art and challenges.

Science.gov (United States)

Li, Chen; Liakata, Maria; Rebholz-Schuhmann, Dietrich

2014-09-01

Networks of molecular interactions explain complex biological processes, and all known information on molecular events is contained in a number of public repositories including the scientific literature. Metabolic and signalling pathways are often viewed separately, even though both types are composed of interactions involving proteins and other chemical entities. It is necessary to be able to combine data from all available resources to judge the functionality, complexity and completeness of any given network overall, but especially the full integration of relevant information from the scientific literature is still an ongoing and complex task. Currently, the text-mining research community is steadily moving towards processing the full body of the scientific literature by making use of rich linguistic features such as full text parsing, to extract biological interactions. The next step will be to combine these with information from scientific databases to support hypothesis generation for the discovery of new knowledge and the extension of biological networks. The generation of comprehensive networks requires technologies such as entity grounding, coordination resolution and co-reference resolution, which are not fully solved and are required to further improve the quality of results. Here, we analyse the state of the art for the extraction of network information from the scientific literature and the evaluation of extraction methods against reference corpora, discuss challenges involved and identify directions for future research. © The Author 2013.

Plastics and health risks.

Science.gov (United States)

Halden, Rolf U

2010-01-01

By 2010, the worldwide annual production of plastics will surpass 300 million tons. Plastics are indispensable materials in modern society, and many products manufactured from plastics are a boon to public health (e.g., disposable syringes, intravenous bags). However, plastics also pose health risks. Of principal concern are endocrine-disrupting properties, as triggered for example by bisphenol A and di-(2-ethylhexyl) phthalate (DEHP). Opinions on the safety of plastics vary widely, and despite more than five decades of research, scientific consensus on product safety is still elusive. This literature review summarizes information from more than 120 peer-reviewed publications on health effects of plastics and plasticizers in lab animals and humans. It examines problematic exposures of susceptible populations and also briefly summarizes adverse environmental impacts from plastic pollution. Ongoing efforts to steer human society toward resource conservation and sustainable consumption are discussed, including the concept of the 5 Rs--i.e., reduce, reuse, recycle, rethink, restrain--for minimizing pre- and postnatal exposures to potentially harmful components of plastics.

Androgen responses to reproductive competition of males pursuing either fixed or plastic alternative reproductive tactics.

Science.gov (United States)

von Kuerthy, Corinna; Ros, Albert F H; Taborsky, Michael

2016-11-15

Alternative reproductive tactics (ARTs), which can be plastic or fixed for life, may be characterized by distinct hormonal profiles. The relative plasticity hypothesis predicts flexible androgen regulation for adult males pursuing plastic tactics, but a less flexible regulation for males using a fixed tactic throughout life. Furthermore, androgen profiles may respond to changes in the social environment, as predicted by the social reciprocity models of hormone/behaviour interactions. The cichlid fish Lamprologus callipterus provides a rare opportunity to study the roles of androgens for male ARTs within a single species, because fixed and plastic ARTs coexist. We experimentally exposed males to competitors pursuing either the same or different tactics to test predictions of the relative plasticity and the social reciprocity models. Androgen profiles of different male types partly comply with predictions derived from the relative plasticity hypothesis: males of the plastic bourgeois/sneaker male trajectory showed different 11-ketotestosterone (11-KT) levels when pursuing either bourgeois or parasitic sneaker male behaviours. Surprisingly, males pursuing the fixed dwarf male tactic showed the highest free and conjugated 11-KT and testosterone (T) levels. Our experimental social challenges significantly affected the free 11-KT levels of bourgeois males, but the androgen responses did not differ between challenges involving different types of competitors. Furthermore, the free T-responses of the bourgeois males correlated with their aggressive behaviour exhibited against competitors. Our results provide new insights into the endocrine responsiveness of fixed and plastic ARTs, confirming and refuting some predictions of both the relative plasticity and the social reciprocity models. © 2016.

Common mechanisms of synaptic plasticity in vertebrates and invertebrates

Science.gov (United States)

Glanzman, David L.

2016-01-01

Until recently, the literature on learning-related synaptic plasticity in invertebrates has been dominated by models assuming plasticity is mediated by presynaptic changes, whereas the vertebrate literature has been dominated by models assuming it is mediated by postsynaptic changes. Here I will argue that this situation does not reflect a biological reality and that, in fact, invertebrate and vertebrate nervous systems share a common set of mechanisms of synaptic plasticity.

Arts, literature and reflective writing as educational strategies to promote narrative reasoning capabilities among physiotherapy students.

Science.gov (United States)

Caeiro, Carmen; Cruz, Eduardo Brazete; Pereira, Carla Mendes

2014-11-01

The use of arts, literature and reflective writing has becoming increasingly popular in health professionals education. However, research examining its contribution as an educational strategy to promote narrative reasoning capabilities is limited, particularly from the students' perspective. This study aimed to explore the final year physiotherapy students' perspectives about the contribution of arts, literature and reflective writing in facilitating narrative reasoning capabilities. Three focus group meetings using a semi-structured interview schedule were carried out to collect data. Focus group sessions were audiotaped and transcribed verbatim. Interpretative phenomenological analysis was used to conduct the study and analyze the transcripts. Three themes emerged: (1) developmental understanding of the patients' experiences; (2) developmental understanding about the self; and (3) embedding reflection in clinical practice. Students emphasized an increasing capability to be sensitive and vicariously experience the patient's experience. Through reflective writing, students reported they became more capable of thinking critically about their practice and learning needs for continuous professional development. Finally, students highlighted the contribution of these strategies in making reflection part of their practice. Final year physiotherapy students reported enhanced skills of narrative reasoning. The findings support the inclusion of these strategies within the undergraduate physiotherapy curricula.

Impact of Bio-Based Plastics on Current Recycling of Plastics

Directory of Open Access Journals (Sweden)

Luc Alaerts

2018-05-01

Full Text Available Bio-based plastics are increasingly appearing in a range of consumption products, and after use they often end up in technical recycling chains. Bio-based plastics are different from fossil-based ones and could disturb the current recycling of plastics and hence inhibit the closure of plastic cycles, which is undesirable given the current focus on a transition towards a circular economy. In this paper, this risk has been assessed via three elaborated case studies using data and information retrieved through an extended literature search. No overall risks were revealed for bio-based plastics as a group; rather, every bio-based plastic is to be considered as a potential separate source of contamination in current recycling practices. For PLA (polylactic acid, a severe incompatibility with PET (polyethylene terephthalate recycling is known; hence, future risks are assessed by measuring amounts of PLA ending up in PET waste streams. For PHA (polyhydroxy alkanoate there is no risk currently, but it will be crucial to monitor future application development. For PEF (polyethylene furanoate, a particular approach for contamination-related issues has been included in the upcoming market introduction. With respect to developing policy, it is important that any introduction of novel plastics is well guided from a system perspective and with a particular eye on incompatibilities with current and upcoming practices in the recycling of plastics.

Residency characteristics that matter most to plastic surgery applicants: a multi-institutional analysis and review of the literature.

2015-06-01

The National Residency Matching Program Match is a very unique process in which applicants and programs are coupled to each other based on a ranking system. Although several studies have assessed features plastic surgery programs look for in applicants, no study in the present plastic surgery literature identifies which residency characteristics are most important to plastic surgery applicants. Therefore, we sought to perform a multi-institutional assessment as to which factors plastic surgery residency applicants consider most important when applying for residency. A validated and anonymous questionnaire containing 37 items regarding various program characteristics was e-mailed to 226 applicants to New York University, Albany, University of Michigan, and University of Southern California plastic surgery residency programs. Applicants were asked to rate each feature on a scale from 1 to 10, with 10 being the most important. The 37 variables were ranked by the sum of the responses. The median rating and interquartile range as well as the mean for each factor was then calculated. A Wilcoxon signed rank test was used to compare medians in rank order. A total of 137 completed questionnaires were returned, yielding a 61% response rate. The characteristics candidates considered most important were impressions during the interview, experiences during away rotations, importance placed on resident training/support/mentoring by faculty, personal experiences with residents, and the amount of time spent in general surgery. The characteristics candidates considered least important were second-look experiences, compensation/benefits, program reputation from Internet forums, accessibility of program coordinator, opportunity for laboratory research, and fellowship positions available at the program. Applicants value personal contact and time spent in general surgery when selecting residency programs. As the number of integrated programs continues to grow, programs will benefit

Cloud-based applications including Box, Dropbox, Google Drive, Evernote, Notability, and Zotero are available for smartphones, tablets, and laptops and have revolutionized the manner in which medical students and surgeons read and utilize plastic surgery literature. Here we provide an overview of the use of Cloud computing in practice and propose an algorithm for organizing the vast amount of plastic surgery literature. Given the incredible amount of data being produced in plastic surgery and other surgical subspecialties, it is prudent for plastic surgeons to lead the process of providing solutions for the efficient organization and effective integration of the ever-increasing data into clinical practice.

Metaphors in the Wisdom Literature of the Hebrew Bible and Contemporary Art

Directory of Open Access Journals (Sweden)

Bálint Károly Zabán

2016-08-01

Full Text Available Biblical wisdom literature is a treasure-trove of powerful metaphors. This article presents a sample of these metaphors and their significant impact on contemporary artwork. The impact is characterized by both appropriation and adaptation, similitude and analogy, respectively. The highlighted metaphors are not merely catalogued but, more or less, analyzed with regard to relevant contemporary artwork. This augments the importance of contemporary biblical literacy analysis and uses it as one of the tools by which it is possible to gauge the impact and interaction, in this case, of the metaphor-world of the wisdom tradition on contemporary art. More importantly, however, this study underscores the relevance of these metaphors for biblical exegesis, hermeneutics, and theology. The analysis of the reception of these metaphors in contemporary artworks undergirds and informs the process of interpretation. The reception of these metaphors in their contemporary art contexts is best understood within the framework of imagery and imagistic language. Metaphor, as a subset of imagery and imagistic language, is foundational for the examined wisdom books, Proverbs, Job, and Qoheleth, and for the relevant contemporary artwork, alike. Moreover, metaphor also constitutes a bridge between the ancient and contemporary context. With this backdrop in mind, this article argues for the necessity of exploring the connections between these wisdom books, metaphor studies, and contemporary artwork.

Transformative art: art as means for long-term neurocognitive change.

Science.gov (United States)

Preminger, Son

2012-01-01

Every artwork leads to a unique experience by the observer or participant, may it be sensory, emotional, cognitive, interactive, or spiritual experience. At the neurobiological level, such experiences are manifested as activation of the corresponding neural networks. Neuroscience has demonstrated that experience, in particular repeated experience, can cause a long-term change in the involved brain circuits (experience-dependent plasticity). This review will discuss the molding and transformative aspect of arts, examining how repeated and on-going experience of arts may alter cognitive, emotional, and behavioral patterns as well as their underlying neural circuits. The application of this approach to cognitive training and neuropsychological rehabilitation methods will be addressed as well. In addition, it will be suggested that this approach to art, as a long-term transformative medium, may lead to a novel viewpoint on art and a different approach to its creation. Artists can design artworks that aspire to form, in addition to one-shot influencing experience, on-going experiences which gradually create a lasting change, possibly improving audiences' neuropsychological functions.

Merging Literature, Visual Art and Physics: Teaching Through Comics

Thompson, R.

2012-12-01

Comics have been around as a form of entertainment for decades. They are often as seen as one of the distracting vices of kids (and adults!), but comics and their more adult version, the graphic novel, are increasingly valued as a legitimate genre of both literature and visual. The APS Outreach Department has teamed up with the APS graphics department to create a series of comics, one featuring Nikola Tesla and his battles with the evil Thomas Edison, and four about laser the APS original super hero Spectra and her continuing battles with such villains as nefarious Miss Alignment and bumbling General Relativity. These comics have struck a delicate balance between education and entertainment being well received by both the comic book and education communities. By creating a compelling comic story that has correct physics, it is possible to use this under-appreciated medium to excite middle-school students who might otherwise be turned off by traditional teaching methods. In merging physics with the art of comics it is crucial to make sure first and foremost that the students enjoy the story and that they feel a connection to the characters. Students are thus hooked and once they are drawn in, the learning happens automatically.

Full Text Available Graffiti movement, born as a result of an effort of the youth, who felt themselves socially excluded and alone, to show their existence and identities during the 1960s, expanded its scope owing to street based artists such as Keith Haring and Jean-Michel Basquiat entering to the galleries, and transformed into an artistic manner of expression having aesthetic concerns by adopting a more inclusive definition ‘street art’. During this transformation of street art,street artists experimented with various methods from many different disciplines and hence created works in a wide range of varieties in terms of plastic and artistic values. Among these disciplines, printmakinghastaken its own place in street artas a discipline thatdeeply influenced street artists.Printmaking has fascinated street artists and become a part of their production process, not only with its philosophy sharing common grounds with street art and advantages in terms of its tecnical practices but also its unique plastic and linear values.Thanks to the opportunities of printmaking, street art has succeeded creating a tremendous impression worldwide, and even positioned itself into today’s greatest museums/gallery halls. This article aims to show how and in what way printmaking has influenced street art being in a transformation since the 1960s, and to put an emphasis on theimportance of printmaking on today’s street art.

Amphibious fishes: evolution and phenotypic plasticity.

Science.gov (United States)

Wright, Patricia A; Turko, Andy J

2016-08-01

Amphibious fishes spend part of their life in terrestrial habitats. The ability to tolerate life on land has evolved independently many times, with more than 200 extant species of amphibious fishes spanning 17 orders now reported. Many adaptations for life out of water have been described in the literature, and adaptive phenotypic plasticity may play an equally important role in promoting favourable matches between the terrestrial habitat and behavioural, physiological, biochemical and morphological characteristics. Amphibious fishes living at the interface of two very different environments must respond to issues relating to buoyancy/gravity, hydration/desiccation, low/high O2 availability, low/high CO2 accumulation and high/low NH3 solubility each time they traverse the air-water interface. Here, we review the literature for examples of plastic traits associated with the response to each of these challenges. Because there is evidence that phenotypic plasticity can facilitate the evolution of fixed traits in general, we summarize the types of investigations needed to more fully determine whether plasticity in extant amphibious fishes can provide indications of the strategies used during the evolution of terrestriality in tetrapods. © 2016.

Synaptic plasticity in drug reward circuitry.

Science.gov (United States)

Winder, Danny G; Egli, Regula E; Schramm, Nicole L; Matthews, Robert T

2002-11-01

Drug addiction is a major public health issue worldwide. The persistence of drug craving coupled with the known recruitment of learning and memory centers in the brain has led investigators to hypothesize that the alterations in glutamatergic synaptic efficacy brought on by synaptic plasticity may play key roles in the addiction process. Here we review the present literature, examining the properties of synaptic plasticity within drug reward circuitry, and the effects that drugs of abuse have on these forms of plasticity. Interestingly, multiple forms of synaptic plasticity can be induced at glutamatergic synapses within the dorsal striatum, its ventral extension the nucleus accumbens, and the ventral tegmental area, and at least some of these forms of plasticity are regulated by behaviorally meaningful administration of cocaine and/or amphetamine. Thus, the present data suggest that regulation of synaptic plasticity in reward circuits is a tractable candidate mechanism underlying aspects of addiction.

Due to its origin from renewable resources, its biodegradability, and recently, its industrial implementation at low costs, poly(lactide) (PLA) is considered as one of the most promising ecological, bio-sourced and biodegradable plastic materials to potentially and increasingly replace traditional petroleum derived polymers in many commodity and engineering applications. Beside its relatively high rigidity (high tensile strength and modulus compared with many common thermoplastics such as poly(ethylene terephthalate) (PET), high impact poly(styrene) (HIPS) and poly(propylene) (PP)), PLA suffers from an inherent brittleness, which can limit its applications especially where mechanical toughness such as plastic deformation at high impact rates or elongation is required. Therefore, the curve plotting stiffness vs. impact resistance and ductility must be shifted to higher values for PLA-based materials, while being preferably fully bio-based and biodegradable upon the application. This review aims to establish a state of the art focused on the recent progresses and preferably economically viable strategies developed in the literature for significantly improve the mechanical performances of PLA. A particular attention is given to plasticization as well as to impact resistance modification of PLA in the case of (reactive) blending PLA-based systems.

Performative, Arts-Based, or Arts-Informed? Reflections on the Development of Arts-Based Research in Music Therapy.

Science.gov (United States)

Ledger, Alison; McCaffrey, Tríona

2015-01-01

Arts-based research (ABR) has emerged in music therapy in diverse ways, employing a range of interpretive paradigms and artistic media. It is notable that no consensus exists as to when and where the arts are included in the research process, or which music therapy topics are most suited to arts-based study. This diversity may pose challenges for music therapists who are developing, reading, and evaluating arts-based research. This paper provides an updated review of arts-based research literature in music therapy, along with four questions for researchers who are developing arts-based research. These questions are 1) When should the arts be introduced? 2) Which artistic medium is appropriate? 3) How should the art be understood? and 4) What is the role of the audience? We argue that these questions are key to understanding arts-based research, justifying methods, and evaluating claims arising from arts-based research. Rather than defining arts-based research in music therapy, we suggest that arts-based research should be understood as a flexible research strategy appropriate for exploring the complexities of music therapy practice. © the American Music Therapy Association 2015.

Art therapy for people with psychosis: a narrative review of the literature.

Science.gov (United States)

Attard, Angelica; Larkin, Michael

2016-11-01

Art therapy enables individuals to use art to creatively express themselves and communicate differently with themselves, others, and their reality. The National Institute for Health and Clinical Excellence guidelines for psychosis and schizophrenia suggest that arts therapies, which include art therapy, are considered to improve negative symptoms of psychosis. We examined the effectiveness of art therapy for people with psychosis and explored whether art therapy is a meaningful and acceptable intervention in this Review. Seven electronic databases were searched for empirical papers that concerned the use of art therapy for adults with psychosis that were published from 2007 onwards. The search identified 18 papers. High-quality quantitative articles provided inconclusive evidence for the effectiveness of art therapy in adults with psychosis. However, high-quality qualitative articles indicated that therapists and clients considered art therapy to be a beneficial, meaningful, and acceptable intervention, although this conclusion was based on a small number of studies. In this Review, we discuss the theoretical, clinical, and methodological issues in light of the development of more robust research, which is needed to corroborate individuals' experiences and guide evidence-based practice.

Describing the concept of infinite among art, literature, philosophy and science: a pedagogical-didactic overview

Directory of Open Access Journals (Sweden)

Paolo Di Sia

2014-09-01

Full Text Available In this work an interesting overview concerning the human attempts in the description of the concept of infinite is presented. This peculiar concept represents a cardinal point in the history of human culture, because man, with different modalities, has always compared with it. Historically the main followed streams were two: the rational and the irrational approaches. In the first approach we find disciplines such as philosophy, mathematics and physics; the second is the domain of literature, arts and religion. Some activities for developing ideas about the intuitive concept of the infinity at the level of compulsory education will be also given.

Kfoury, Georgio; Raquez, Jean-Marie; Hassouna, Fatima; Odent, Jérémy; Toniazzo, Valérie; Ruch, David; Dubois, Philippe

2013-01-01

Due to its origin from renewable resources, its biodegradability, and recently, its industrial implementation at low costs, poly(lactide) (PLA) is considered as one of the most promising ecological, bio-sourced and biodegradable plastic materials to potentially and increasingly replace traditional petroleum derived polymers in many commodity and engineering applications. Beside its relatively high rigidity [high tensile strength and modulus compared with many common thermoplastics such as poly(ethylene terephthalate) (PET), high impact poly(styrene) (HIPS) and poly(propylene) (PP)], PLA suffers from an inherent brittleness, which can limit its applications especially where mechanical toughness such as plastic deformation at high impact rates or elongation is required. Therefore, the curve plotting stiffness vs. impact resistance and ductility must be shifted to higher values for PLA-based materials, while being preferably fully bio-based and biodegradable upon the application. This review aims to establish a state of the art focused on the recent progresses and preferably economically viable strategies developed in the literature for significantly improve the mechanical performances of PLA. A particular attention is given to plasticization as well as to impact resistance modification of PLA in the case of (reactive) blending PLA-based systems. PMID:24790960

2016-01-01

The growth and acceptance of smartphones among clinicians has been remarkable over the last decade. Over 87% of doctors use a smartphone or tablet capable of running third-party software known as applications (apps). In the field of plastic surgery, apps have been designed for personal practice development, education, clinical tools and guidelines, and entertainment. This study reviews the literature on apps related to plastic surgery and determines the number and types of apps available. A systematic review of the literature was performed to find articles written about plastic surgery applications. Queries were run in the Apple iPhone iOS App store and Google Play using the term "plastic surgery." Apps were reviewed for ratings, downloads, and cost. In addition, apps were categorized based on purpose. Categories include practice development, media/literature, clinical tool and guideline apps, or recreation. The literature search yielded 8 articles for review, 2 articles focused on categorizing apps and 6 articles focused on describing useful apps. Searching Apple's iTunes (iOS) store identified 273 and Google Play identified 250 apps related to plastic surgery; since 2013, a 62%, and 580% increase, respectively. The iOS store included practice development (46%), recreation (26%), media/literature (14%), and clinical tool and guideline (11%). Google Play store included recreation apps (44%), practice development (24%), clinical tools and guidelines (11%), and media and literature (9%). Apps related to the field of plastic surgery are increasing in prevalence. The content of these apps are variable, and the majority are intended for marketing and development of private practices. Apps linking to literature, texts, study materials, and clinical tools and guidelines are developed for both practicing plastic surgeons and surgical trainees. Finding "useful" apps takes time because searches are often complicated by a variety of apps.

2017-06-01

Plastics in the marine environment have become a major concern because of their persistence at sea, and adverse consequences to marine life and potentially human health. Implementing mitigation strategies requires an understanding and quantification of marine plastic sources, taking spatial and temporal variability into account. Here we present a global model of plastic inputs from rivers into oceans based on waste management, population density and hydrological information. Our model is calibrated against measurements available in the literature. We estimate that between 1.15 and 2.41 million tonnes of plastic waste currently enters the ocean every year from rivers, with over 74% of emissions occurring between May and October. The top 20 polluting rivers, mostly located in Asia, account for 67% of the global total. The findings of this study provide baseline data for ocean plastic mass balance exercises, and assist in prioritizing future plastic debris monitoring and mitigation strategies.

Wang, Chong-qing; Wang, Hui; Fu, Jian-gang; Liu, You-nian

2015-07-01

The sharp increase of plastic wastes results in great social and environmental pressures, and recycling, as an effective way currently available to reduce the negative impacts of plastic wastes, represents one of the most dynamic areas in the plastics industry today. Froth flotation is a promising method to solve the key problem of recycling process, namely separation of plastic mixtures. This review surveys recent literature on plastics flotation, focusing on specific features compared to ores flotation, strategies, methods and principles, flotation equipments, and current challenges. In terms of separation methods, plastics flotation is divided into gamma flotation, adsorption of reagents, surface modification and physical regulation. Copyright © 2015 Elsevier Ltd.

Vagabond Figures in Slovenian Visual Art and Literature at the Beginning of the Twentieth Century

Directory of Open Access Journals (Sweden)

Robert Simonišek

2011-07-01

Full Text Available The article explores the relationship between visual and literary motifs in Slovenian painting (and illustration, graphics, and drawing and literature (both prose and poetry at the beginning of the twentieth century. It uses examples to show the popularity and rich variety of vagabond figures and their transformations and reciprocity at the level of the painting/text. However, a distinctive feature of this article is that it places the subject within the context of hermeneutics, a method that has not been used in Slovenian art history. In addition, it also reveals the symbolic complexity of the vagabond figure in the context of writers, other works, and social-historical circumstances. The emphasis is placed on artists that showed enthusiasm for this figure as a subject during the Belle Époque and also those that followed the very popular bohemian lifestyle in their everyday lives. The reception of Slovenian folk and traditional motifs from the past produced visual and semantic oscillation in which the phenomena of vagabond figures were systematized and interpreted. Many painters (e.g., Gvidon Birolla, and Maksim Gaspari and writers (e.g., Oton Župančič, Cvetko Golar, and Ivan Cankar clung to the Slovenian tradition with romantic overtones and, in line with their artistic atmosphere, integrated vagabond figures into typical Slovenian landscapes or environments. Some of them followed Symbolism and modernized the figures with autobiographical references (e.g., Fran Tratnik. The situation among the youngest generation of artists in particular showed that they managed to “escape” from copying traditional motifs and instead used them in a modern form in the “here and now” (e.g., Ivan Cankar. The discrepancy between the lack of the vagabond theme in oil painting and strong diversification in illustration, drawing, graphics, and literature could be explained by consumers’ perceived difference between “high” and “popular” art.

The teaching-learning process of plastic expression in students with Down syndrome

Full Text Available The drawing constitutes a means through which the child expresses the level of physical, mental, emotional and creative development achieved and plays an important role in the plastic expression. The study took into account the identification of needs in the teaching - learning process of plastic expression in students with Down syndrome, for which a didactic strategy was designed that contains actions of a teaching nature and establishes interdisciplinary links between the different subjects of the curriculum. The investigative process was conducted on a dialectical-materialist basis and methods were used at the theoretical, empirical and statistical-mathematical levels, such as: documentary analysis, interview, drawing technique, among others. Five students with Down syndrome participated in the study of the special school "28 de Enero" of Pinar del Río and the instructor who directs the workshops of creation of Plastic Arts. The investigations allowed to determine the regularities that distinguish the process of teaching - learning of the plastic expression in these students, as well as the needs of the Plastic Arts instructor for the conduction of said process. The didactic strategy allowed the process of teaching - learning of the plastic expression to encourage creativity and the development of motor skills, from the projection of actions that contribute to the diagnosis and treatment of this process in order to achieve the maximum integral development possible and the preparation for the independent adult life of the school student with Down syndrome.

Wherefore Art Thou, Homeo(stasis? Functional Diversity in Homeostatic Synaptic Plasticity

Directory of Open Access Journals (Sweden)

Bridget N. Queenan

2012-01-01

Full Text Available Homeostatic plasticity has emerged as a fundamental regulatory principle that strives to maintain neuronal activity within optimal ranges by altering diverse aspects of neuronal function. Adaptation to network activity is often viewed as an essential negative feedback restraint that prevents runaway excitation or inhibition. However, the precise importance of these homeostatic functions is often theoretical rather than empirically derived. Moreover, a remarkable multiplicity of homeostatic adaptations has been observed. To clarify these issues, it may prove useful to ask: why do homeostatic mechanisms exist, what advantages do these adaptive responses confer on a given cell population, and why are there so many seemingly divergent effects? Here, we approach these questions by applying the principles of control theory to homeostatic synaptic plasticity of mammalian neurons and suggest that the varied responses observed may represent distinct functional classes of control mechanisms directed toward disparate physiological goals.

Review of the partitioning of chemicals into different plastics: Consequences for the risk assessment of marine plastic debris

International Nuclear Information System (INIS)

O'Connor, Isabel A.; Golsteijn, Laura; Hendriks, A. Jan

2016-01-01

Marine plastic debris are found worldwide in oceans and coastal areas. They degrade only slowly and contain chemicals added during manufacture or absorbed from the seawater. Therefore, they can pose a long-lasting contaminant source and potentially transfer chemicals to marine organisms when ingested. In order to assess their risk, the contaminant concentration in the plastics needs to be estimated and differences understood. We collected from literature plastic water partition coefficients of various organic chemicals for seven plastic types: polydimethylsiloxane (PDMS), high-density, low-density and ultra-high molecular weight polyethylene (LDPE, HDPE, UHMWPE), polystyrene (PS), polypropylene (PP), and polyvinyl chloride (PVC). Most data was available for PDMS (1060) and LDPE (220), but much less for the remaining plastics (73). Where possible, regression models were developed and the partitioning was compared between the different plastic types. The partitioning of chemicals follows the order of LDPE ≈ HDPE ≥ PP > PVC ≈ PS. Data describing the impact of weathering are urgently needed. - Highlights: • Comparison of organic chemicals partitioning into seven plastic types • Linear correlation between plastic-water partition coefficient K pw and K ow • More data is needed for polypropylene, polystyrene and polyvinyl chloride. • In all plastic types, most K pw were similar to/smaller than the corresponding K ow .

Prendergast, Christina; Ketteler, Erika; Evans, Gregory

2017-03-01

A career as a plastic surgeon is both rewarding and challenging. The road to becoming a surgeon is a long arduous endeavor and can bring significant challenges not only to the surgeon but their family. A study by the American College of Surgeons (ACS) suggested that over 40% of surgeons experience burnout and a recent survey of American Society of Plastic Surgeons (ASPS) showed that more than one-fourth of plastic surgeons have signs of professional burnout. Burnout is a state of physical and mental exhaustion. The three main components of burnout are emotional exhaustion, depersonalization, and reduced personal accomplishment. Exhaustion occurs as a result of emotional demands. Depersonalization refers to a cynical, negative or a detached response to patient care. The reduced accomplishment refers to a belief that one can no longer work effectively. There has been a recent explosion in the literature characterizing burnout within the surgical profession. Reports of burnout, burnout victims, and burnout syndrome are filling the medical literature, books, blogs, and social media across all different specialties. Burnout in a plastic surgeon has negative and potentially fatal repercussions to the surgeon, their family, their patients, their staff, colleagues, coworkers, and their organization. To date, there are a limited number of publications addressing burnout in the plastic surgery community. The goals of this paper are to review the symptoms of burnout, its effect on plastic surgeons, and discuss potential solutions for burnout prevention and physician wellness.

Use of recycled plastics in concrete: A critical review.

Science.gov (United States)

Gu, Lei; Ozbakkaloglu, Togay

2016-05-01

Plastics have become an essential part of our modern lifestyle, and the global plastic production has increased immensely during the past 50years. This has contributed greatly to the production of plastic-related waste. Reuse of waste and recycled plastic materials in concrete mix as an environmental friendly construction material has drawn attention of researchers in recent times, and a large number of studies reporting the behavior of concrete containing waste and recycled plastic materials have been published. This paper summarizes the current published literature until 2015, discussing the material properties and recycling methods of plastic and the influence of plastic materials on the properties of concrete. To provide a comprehensive review, a total of 84 studies were considered, and they were classified into sub categories based on whether they dealt with concrete containing plastic aggregates or plastic fibers. Furthermore, the morphology of concrete containing plastic materials is described in this paper to explain the influence of plastic aggregates and plastic fibers on the properties of concrete. The properties of concretes containing virgin plastic materials were also reviewed to establish their similarities and differences with concrete containing recycled plastics.

Benthic plastic debris in marine and fresh water environments.

Science.gov (United States)

Corcoran, Patricia L

2015-08-01

This review provides a discussion of the published literature concerning benthic plastic debris in ocean, sea, lake, estuary and river bottoms throughout the world. Although numerous investigations of shoreline, surface and near-surface plastic debris provide important information on plastic types, distribution, accumulation, and degradation, studies of submerged plastic debris have been sporadic in the past and have become more prominent only recently. The distribution of benthic debris is controlled mainly by combinations of urban proximity and its association with fishing-related activities, geomorphology, hydrological conditions, and river input. High density plastics, biofouled products, polymers with mineral fillers or adsorbed minerals, and plastic-metal composites all have the potential to sink. Once deposited on the bottoms of water basins and channels, plastics are shielded from UV light, thus slowing the degradation process significantly. Investigations of the interactions between benthic plastic debris and bottom-dwelling organisms will help shed light on the potential dangers of submerged plastic litter.

Prospects of pyrolysis oil from plastic waste as fuel for diesel engines: A review

Mangesh, V. L.; Padmanabhan, S.; Ganesan, S.; PrabhudevRahul, D.; Reddy, T. Dinesh Kumar

2017-05-01

The purpose ofthis study is to review the existing literature about chemical recycling of plastic waste and its potential as fuel for diesel engines. This is a review covering on the field of converting waste plastics into liquid hydrocarbon fuels for diesel engines. Disposal and recycling of waste plastics have become an incremental problem and environmental threat with increasing demand for plastics. One of the effective measures is by converting waste plastic into combustible hydrocarbon liquid as an alternative fuel for running diesel engines. Continued research efforts have been taken by researchers to convert waste plastic in to combustible pyrolysis oil as alternate fuel for diesel engines. An existing literature focuses on the study of chemical structure of the waste plastic pyrolysis compared with diesel oil. Converting waste plastics into fuel oil by different catalysts in catalytic pyrolysis process also reviewed in this paper. The methodology with subsequent hydro treating and hydrocracking of waste plastic pyrolysis oil can reduce unsaturated hydrocarbon bonds which would improve the combustion performance in diesel engines as an alternate fuel.

Investigation on neutron/gamma discrimination phenomena in plastic scintillators

International Nuclear Information System (INIS)

Blanc, Pauline

2014-01-01

This PhD topic was born from misunderstandings and incomplete knowledge of the mechanism and relative effectiveness of neutron and gamma-ray (n/γ) discrimination between plastic scintillators compared to liquid scintillators. The shape of the light pulse these materials generate following interaction with an ionizing particle (predominantly recoil protons in the case of neutrons and electrons in the case of gamma-rays) is different in time in a way that depends on the detected particle (nature and energy). It is this fact that enables separation (PSD). The behavior in liquid scintillators has been extensively studied experimentally for practical applications. Only recently has it been shown that a weak separation can also be achieved using specially prepared plastics. The study of this system presents an open field and the understanding of both liquids and plastics with respect to their PSD properties is far from complete. This work is dedicated to exploring the fundamental photophysical phenomena at play in the generation of luminescence emission, following the interaction of ionizing radiation with organic scintillators. For this purpose, firstly a detailed literature review of the state-of-the-art has been conducted extending from 1960 to the present day. Secondly a complete characterization of the main scintillating materials has been conducted to define their fluorescence properties and the characteristics of their scintillation under irradiation. Thirdly a proton beam has been used to simulate recoil protons to quantify under controlled laboratory conditions their specific energy deposition in a plastic scintillator with PSD properties. The fourth part of this thesis is devoted to the study of PSD efficiency of scintillators as a function of their molecular structure. This investigation has led to a plastic scintillator prepared in our laboratory with good PSD properties and a patent submission. Finally, photophysical experiments were performed using a

The advanced Large-Area Plastic Scintillator (ALPS) Project at Pacific Northwest National Laboratory investigated possible technological avenues for substantially advancing the state-of-the-art in gamma-ray detection via large-area plastic scintillators. The three predominant themes of these investigations comprised the following: * Maximizing light collection efficiency from a single large-area sheet of plastic scintillator, and optimizing hardware event trigger definition to retain detection efficiency while exploiting the power of coincidence to suppress single-PMT 'dark current' background; * Utilizing anti-Compton vetoing and supplementary spectral information from a co-located secondary, or 'Back' detector, to both (1) minimize Compton background in the low-energy portion of the 'Front' scintillator's pulse-height spectrum, and (2) sharpen the statistical accuracy of the front detector's low-energy response prediction as implemented in suitable energy-windowing algorithms; and * Investigating alternative materials to enhance the intrinsic gamma-ray detection efficiency of plastic-based sensors

2017-09-01

Work in the visual arts, performing arts, and writing can involve exposures to occupational hazards, including hazardous materials, equipment, and conditions, but few art workplaces have strong occupational health resources. Literature searches were conducted for articles that illustrate these concerns. Medical databases were searched for art-related health articles. Other sources were also reviewed, including, unindexed art-health publications, and popular press articles. Information was located that described some exposed populations, art-related hazards, and resulting disorders. Anecdotal reports were used when more complete data were not available. Health hazards in the arts are significant. Occupational health professionals are familiar with most of these concerns and understand their treatment and prevention. The occupational health approach can reduce the health hazards encountered by at-risk art workers. Additional research would benefit these efforts. Resources for further information are available.

The radiologic aesthetics of some body parts and internal organs have inspired certain artists to create specific works of art. Our aim was to describe the link between radiology and fine art. We explored 13,625 artworks in the literature produced by 2049 artists and found several thousand photographs in an online image search. The examination revealed 271 radiologic artworks (1.99%) created by 59 artists (2.88%) who mainly applied radiography, sonography, CT, and MRI. Some authors produced radiologic artistic photographs, and others used radiologic images to create artful compositions, specific sculptures, or digital works. Many radiologic artworks have symbolic, metaphoric, or conceptual connotations. Radiology is clearly becoming an original and important field of modern art.

A calculational round robin in elastic-plastic fracture mechanics

International Nuclear Information System (INIS)

Larsson, L.H.

1983-01-01

Eighteen organisations participated in this elastic-plastic fracture mechanics (EPFM) numerical analysis round robin which treated the same three-point bend problem as a similar round robin conducted by ASTM four years earlier. The work involved the calculation of overall deformation, J, CTOD and crack profile using plane strain elastic-plastic finite element analysis for a monotonically increasing load up to a maximum deformation which was far beyond the elastic regime. It was found that all of the elastic solutions were accurate to within a few per cent. In the elastic-plastic regime, however, there was a large scatter of the results, increasing with increasing plastic deformation and roughly of the same order as in the ASTM round robin which contained ten solutions. No significant progress has taken place in the state of the art of numerical EPFM analysis over the four-year interval. The reasons for this scatter and tentative conclusions on the most suitable numerical analysis methods in EPFM are discussed. (author)

Marine debris ingestion and Thayer's law - The importance of plastic color.

Science.gov (United States)

Santos, Robson G; Andrades, Ryan; Fardim, Lorena M; Martins, Agnaldo Silva

2016-07-01

In recent years marine plastic pollution has gained considerable attention as a significant threat to marine animals. Despite the abundant literature related to marine debris ingestion, only a few studies attempted to understand the factors involved in debris ingestion. Plastic ingestion is commonly attributed to visual similarities of plastic fragments to animal's prey items, such as plastic bags and jellyfish. However, this simple explanation is not always coherent with the variety of debris items ingested and with the species' main prey items. We assess differences in the conspicuousness of plastic debris related to their color using Thayer's law to infer the likelihood that visual foragers detect plastic fragments. We hypothesize that marine animals that perceive floating plastic from below should preferentially ingest dark plastic fragments, whereas animals that perceive floating plastic from above should select for paler plastic fragments.

Art and human nature

Directory of Open Access Journals (Sweden)

Mirta Toledo

2008-06-01

Full Text Available This article presents a visual artist’s point of view about art. This view confronts the Eurocentric traditional cannon with some ignored, but valuable traditions, thus proposing a contra-canon. These ideas are examined on the light of a variety of sources, including prehistoric, pre-Columbian, and 20th century art expressions, in a variety of media, from sculpture to literature. Recent art expressions are characterized by their incorporation of minority values and perspectives that challenge “universal” views. Using samples of works from Latino and African American artists, the author shows that, even today, art is a means to know the world and its people, to exhibit personal life, to create personal symbolism, and to show one’s identity or the search for it. Like the human nature it represents, art has multiple faces.

Case-control study designs are commonly used. However, many published case-control studies are not true case-controls and are in fact mislabeled. The purpose of this study was to identify all case-control studies published in the top three plastic surgery journals over the past 10 years, assess which were truly case-control studies, clarify the actual design of the articles, and address common misconceptions. MEDLINE, Embase, and Web of Science databases were searched for case-control studies in the three highest-impact factor plastic surgery journals (2005 to 2015). Two independent reviewers screened the resulting titles, abstracts, and methods, if applicable, to identify articles labeled as case-control studies. These articles were appraised and classified as true case-control studies or non-case-control studies. The authors found 28 articles labeled as case-control studies. However, only six of these articles (21 percent) were truly case-control designs. Of the 22 incorrectly labeled studies, one (5 percent) was a randomized controlled trial, three (14 percent) were nonrandomized trials, two (9 percent) were prospective comparative cohort designs, 14 (64 percent) were retrospective comparative cohort designs, and two (9 percent) were cross-sectional designs. The mislabeling was worse in recent years, despite increases in evidence-based medicine awareness. The majority of published case-control studies are not in fact case-control studies. This misunderstanding is worsening with time. Most of these studies are actually comparative cohort designs. However, some studies are truly clinical trials and thus a higher level of evidence than originally proposed.

Art as behaviour--an ethological approach to visual and verbal art, music and architecture.

Science.gov (United States)

Sütterlin, Christa; Schiefenhövel, Wulf; Lehmann, Christian; Forster, Johanna; Apfelauer, Gerhard

2014-01-01

In recent years, the fine arts, architecture, music and literature have increasingly been examined from the vantage point of human ethology and evolutionary psychology. In 2011 the authors formed the research group 'Ethology of the Arts' concentrating on the evolution and biology of perception and behaviour. These novel approaches aim at a better understanding of the various facets represented by the arts by taking into focus possible phylogenetic adaptations, which have shaped the artistic capacities of our ancestors. Rather than culture specificity, which is stressed e.g. by cultural anthropology and numerous other disciplines, universal human tendencies to perceive, feel, think and behave are postulated. Artistic expressive behaviour is understood as an integral part of the human condition, whether expressed in ritual, visual, verbal or musical art. The Ethology of the Arts-group's research focuses on visual and verbal art, music and built environment/architecture and is designed to contribute to the incipient interdisciplinarity in the field of evolutionary art research.

Threat of plastic pollution to seabirds is global, pervasive, and increasing

OpenAIRE

Wilcox, C; Van Sebille, E; Hardesty, BD

2015-01-01

Plastic pollution in the ocean is a rapidly emerging global environmental concern, with high concentrations (up to 580,000 pieces per km2) and a global distribution, driven by exponentially increasing production. Seabirds are particularly vulnerable to this type of pollution and are widely observed to ingest floating plastic. We used a mixture of literature surveys, oceanographic modeling, and ecological models to predict the risk of plastic ingestion to 186 seabird species globally. Impacts ...

Stuckey, Heather L; Nobel, Jeremy

2010-02-01

This review explores the relationship between engagement with the creative arts and health outcomes, specifically the health effects of music engagement, visual arts therapy, movement-based creative expression, and expressive writing. Although there is evidence that art-based interventions are effective in reducing adverse physiological and psychological outcomes, the extent to which these interventions enhance health status is largely unknown. Our hope is to establish a foundation for continued investigation into this subject and to generate further interest in researching the complexities of engagement with the arts and health.

Martial arts injuries.

Pieter, Willy

2005-01-01

To review the current evidence for the epidemiology of pediatric injuries in martial arts. The relevant literature was searched using SPORT DISCUS (keywords: martial arts injuries, judo injuries, karate injuries, and taekwondo injuries and ProQuest (keywords: martial arts, taekwondo, karate, and judo), as well as hand searches of the reference lists. In general, the absolute number of injuries in girls is lower than in boys. However, when expressed relative to exposure, the injury rates of girls are higher. Injuries by body region reflect the specific techniques and rules of the martial art. The upper extremities tend to get injured more often in judo, the head and face in karate and the lower extremities in taekwondo. Activities engaged in at the time of injury included performing a kick or being thrown in judo, while punching in karate, and performing a roundhouse kick in taekwondo. Injury type tends to be martial art specific with sprains reported in judo and taekwondo and epistaxis in karate. Injury risk factors in martial arts include age, body weight and exposure. Preventive measures should focus on education of coaches, referees, athletes, and tournament directors. Although descriptive research should continue, analytical studies are urgently needed.

Identity of the work of art

Directory of Open Access Journals (Sweden)

Ristić Stefan

2010-01-01

Full Text Available The paper intends to determine the identity of the work of art in visual arts, music and literature. The discussion is of ontological nature. Particular attention is given to the problem of imitation of works of art in different arts, making a distinction between two types of imitation: fakes and forgeries. The first type is found only within the arts where the work of art is a singular physical object, i.e. with the so called autographic arts, whereas the second type can also be found in other, allographic arts, although less commonly. The problem of the imitation of works of art is closely related with the issue concerning the possibility of reducing the work of art to a formal symbolic system which would serve as a definition of the work of art. The discussion shows that a consistent analysis of the ontological status of the work of art in different art forms provides results that may seem at the first glance unintuitive and surprising.

The traditional, the innovative, the ephemeral: conception, realization, intervention in contemporary art

Full Text Available The traditional, the innovative, the ephemeral: conception, realization, intervention in contemporary art. One must consider the traditional, the innovative and also the ephemeral related to the artistic intentions and thus to the interventions on works of contemporary art, for which the concepts of originality and authenticity do not always correspond. The Brandian vision and point of view do not completely resolve the problematics relative to restoration and conservation: artists realize their artifacts with the intention of undermining tradition or, however, of interpreting it in an unusual way. There are, therefore, cases when a diagnostic-analytical and conservative intervention is possible correspondently to the different and numerous typologies of the materials (poor, plastic, industrial and techniques (collage, enamel on rubber foam, paint on textile or plastic, neon. A vocation for the ephemeral can be transformed into the adoption of deteriorated materials or into the realization of works of conceptual art and net-art. Some case studies are treated in the comparison of art works of different age. The solutions to the aforementioned problematics are offered and the importance of the involvement of the historical-technical experts, authors and manufacturers of the materials used in the artifacts is highlighted. Finally the procedure of intervention cannot be the same for all works of contemporary art. One must employ a methodology based on the critical study, not only of the materials used but also of the philosophy and creative conceptual intentions of the artist.

Humanisme et art

Science.gov (United States)

Bejjani, Gérard

2014-06-01

Humanism and art - To what extent does art have a major role to play in twenty-first-century humanism? Greek philosophers believed that its purpose was ethical, serving to improve people by confronting them with evil and purging their passions. Nineteenth-century literature saw it as edifying and utilitarian, and for two centuries it was associated with the principles of goodness, truth, freedom and resistance to oppression, part of a general movement towards greater human solidarity based on shared experience. Literature and, more recently, cinema have been the most effective at defending human values. But the role of culture is not purely ethical: it also encourages a purely aesthetic reflection that has become the sole truth of creation. The aspiration to beauty reminds us that mankind is no ordinary species, but a reminiscence of the ideal objectified in works of art. The quest for the absolute is that of artists who draw on the lessons of history to come closer to the essence of spirituality and the cosmic centre of the world. Artistic vision is the ultimate vocation of humanity, achieving greatness and dignity in a constant quest for illumination, engaging in dialogue with the transcendent, and perhaps even transcending our own finiteness.

The pollution of the marine environment by plastic debris: a review.

Science.gov (United States)

Derraik, José G B

2002-09-01

The deleterious effects of plastic debris on the marine environment were reviewed by bringing together most of the literature published so far on the topic. A large number of marine species is known to be harmed and/or killed by plastic debris, which could jeopardize their survival, especially since many are already endangered by other forms of anthropogenic activities. Marine animals are mostly affected through entanglement in and ingestion of plastic litter. Other less known threats include the use of plastic debris by "invader" species and the absorption of polychlorinated biphenyls from ingested plastics. Less conspicuous forms, such as plastic pellets and "scrubbers" are also hazardous. To address the problem of plastic debris in the oceans is a difficult task, and a variety of approaches are urgently required. Some of the ways to mitigate the problem are discussed.

Art and dystonia.

Science.gov (United States)

Garcia-Ruiz, Pedro J; Slawek, Jaroslaw; Sitek, Emilia J; Martinez Castrillo, Juan Carlos

2015-09-15

Dystonia has a recent history in medicine. Focal dystonia was described in the 19th century by classic authors including Gowers, whilst generalized dystonia was described at the turn of the century. However, it is possible to find precise descriptions of dystonia in art, centuries before the medical definition. We have reviewed several pieces of art (sculpture, painting and literature) across the history that might represent descriptions of dystonia, from ancient period to nowadays. In classic times, the first reference to abnormal postures can be tracked back to the new Empire of Egypt (equinus foot), not to mention some recently described examples of dystonia from the Moche sculptures in Peru or Veracruz culture from Mexico. In Middle Ages it is possible to find many examples of sculptures in European cathedrals representing peasants with dramatic, presumably dystonic postures that coexist with amputation of limbs. This unique combination of dystonia and limb amputation probably represents ergotism. The painters Brueghel, Ribera and Velazquez also represented figures with postures likely to be dystonic. Literature is also a source of precise pre-neurological descriptions, especially during the 19th century. In David Copperfield, Dickens depicts characters with generalized dystonia (Uriah Heep), cervical dystonia (Mr. Sharp) and spasmodic dysphonia (Mr Creakle). Finally, even in modern Art (19th and 20th centuries), there are dramatic descriptions of abnormal postures that are likely to be dystonic, such as painful cervical dystonia (Brancusi), cervical dystonia with sensory trick (Modigliani) and upper limb dystonia (Wyspianski). However some postures presented in works of art may simply be a form of artistic expression and only bear unintentional resemblance to the dystonic postures. Art may be a source of neurological information, and that includes primary and secondary dystonia. Copyright © 2015 Elsevier B.V. All rights reserved.

Brominated flame retardant emissions from the open burning of five plastic wastes and implications for environmental exposure in China

International Nuclear Information System (INIS)

Ni, Hong-Gang; Lu, Shao-You; Mo, Ting; Zeng, Hui

2016-01-01

Based on the most widely used plastics in China, five plastic wastes were selected for investigation of brominated flame retardant (BFR) emission behaviors during open burning. Considerable variations were observed in the emission factors (EF) of polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecanes (HBCDs) from the combustion of different plastic wastes. Distribution of BFR output mass showed that ΣPBDE was emitted mainly by the airborne particle (51%), followed by residual ash (44%) and the gas phase (5.1%); these values for ΣHBCD were 62%, 24%, and 14%, respectively. A lack of mass balance after the burning of the plastic wastes for some congeners (output/input mass ratios > 1) suggested that formation and survival exceeded PBDE decomposition during the burns. However, that was not the case for HBCD. A comparison with literature data showed that the open burning of plastic waste is major source of PBDE compared to regulated combustion activities. Even for state-of-the-art waste incinerators equipped with sophisticated complex air pollution control technologies, BFRs are released on a small scale to the environment. According to our estimate, ΣPBDE release to the air and land from municipal solid waste (MSW) incineration plants in China in 2015 were 105 kg/year and 7124 kg/year. These data for ΣHBCD were 25.5 and 71.7 kg/year, respectively. Considering the fact that a growing number of cities in China are switching to incineration as the preferred method for MSW treatment, our estimate is especially important. This study provides the first data on the environmental exposure of BFRs emitted from MSW incineration in China. - Highlights: • Airborne particle and residue ash are two major emissions from burns of plastic waste. • Mass unbalance showed formation of PBDE occurred during burning process. • Open burning of plastic waste is major source of PBDE compared to industrial sources. • BFRs in residual ash of waste combustion would be

The present work investigates a new approach to formulating a rate-independent strain gradient theory for crystal plasticity. The approach takes as offset recent discussions published in the literature for isotropic plasticity, and a key ingredient of the present work is the manner in which...... a gradient enhanced effective slip measure governs hardening evolution. The effect of both plastic strains and plastic strain gradients are combined into this scalar effective slip quantity, the energy associated with plastic strain is dissipative (unrecoverable), while the energy from plastic strain...... gradients is recoverable (free). The framework developed forms the basis of a finite element implementation and is demonstrated on benchmark problems designed to bring out effects such as strengthening and hardening. Monotonic loading and plane strain deformation is assumed throughout, but despite this, non...

Perioperative antibiotic usage by facial plastic surgeons: national survey results and comparison with evidence-based guidelines.

Science.gov (United States)

Grunebaum, Lisa Danielle; Reiter, David

2006-01-01

To determine current practice for use of perioperative antibiotics among facial plastic surgeons, to determine the extent of use of literature support for preferences of facial plastic surgeons, and to compare patterns of use with nationally supported evidence-based guidelines. A link to a Web site containing a questionnaire on perioperative antibiotic use was e-mailed to more than 1000 facial plastic surgeons in the United States. Responses were archived in a dedicated database and analyzed to determine patterns of use and methods of documenting that use. Current literature was used to develop evidence-based recommendations for perioperative antibiotic use, emphasizing current nationally supported guidelines. Preferences varied significantly for medication used, dosage and regimen, time of first dose relative to incision time, setting in which medication was administered, and procedures for which perioperative antibiotic was deemed necessary. Surgical site infection in facial plastic surgery can be reduced by better conformance to currently available evidence-based guidelines. We offer specific recommendations that are supported by the current literature.

Suffocation caused by plastic wrap covering the face combined with nitrous oxide inhalation.

Leth, Peter Mygind; Astrup, Birgitte Schmidt

2017-09-01

Suicide using a combination of a plastic bag over the head and inhalation of a non-irritating gas, such as helium, argon or nitrogen, has been reported in the literature. Here an unusual suicide method in a 17-year old man by suffocation from covering the face with household plastic wrap, combined with nitrous oxide inhalation, is presented. The case was reviewed based on police, autopsy and hospital reports. A PubMed search for scientific literature related to nitrous oxide abuse and suicide by suffocation was performed and our findings discussed in relation to the scientific literature found. The deceased was a 17-year old man who was found with the nose and mouth closed with a piece of kitchen plastic wrap. The plastic wrap had been removed prior to autopsy. Autopsy findings were suggestive of asphyxia, but were otherwise negative. Nitrous oxide was detected in the brain and lung tissue with headspace-gas chromatography-mass spectrometry (headspace-GCMS). The cause of death was assumed to be suffocation caused by plastic wrap covering the face, combined with nitrous oxide inhalation. Suicide was suspected because of a history of depression for several months. Nitrous oxide, also known as laughing gas, has a euphoric effect and is used as a recreational inhalant drug that can be purchased legally. Deaths caused by recreational nitrous oxide abuse are rare but may occur if used in combination with a plastic bag over the head. This is the first report of suicide by suffocation by external obstruction combined with nitrous oxide inhalation.

A calculational round robin in elastic-plastic fracture mechanics

International Nuclear Information System (INIS)

Larsson, L.H.

Eighteen organizations participated in this round robin which treated the same three-point bend problem as an ASTM round robin four years earlier. Overall deformation, J, CTOD and crack profile were the main results required using plane strain elastic-plastic finite element analysis for a monotonically increasing load up to a maximum deformation which was far beyond the elastic regime. All elastic solutions were accurate to within a few percent. In the elastic-plastic regime, however, there was a large scatter of the results, increasing with increasing plastic deformation and roughly of the same order as in the ASTM round robin which contained ten solutions. Apparently no significant progress has taken place in the state of the art of numerical EPFM analysis in four years time. The paper discusses the reasons for this scatter and draws tentative conclusions on the most suitable numerical analysis methods in EPFM. (Auth.)

Danish Sixties Avant-Garde and American Minimal Art

Directory of Open Access Journals (Sweden)

Max Ipsen

2007-05-01

Full Text Available Denmark is peripheral in the history of minimalism in the arts. In an international perspective Danish artists made almost no contributions to minimalism, according to art historians. But the fact is that Danish artists made minimalist works of art, and they did it very early. Art historians tend to describe minimal art as an entirely American phenomenon. America is the centre, Europe the periphery that lagged behind the centre, imitating American art. I will try to query this view with examples from Danish minimalism. I will discuss minimalist tendencies in Danish art and literature in the 1960s, and I will examine whether one can claim that Danish artists were influenced by American minimal art.

Adaptive Resonance Theory (ART) is one of the successful approaches to resolving "the plasticity-stability dilemma" in neural networks, and its supervised learning model called ARTMAP is a powerful tool for classification. Among several improvements, such as Fuzzy or Gaussian based models, the state of art model is Bayesian based one, while solving the drawbacks of others. However, it is known that the Bayesian approach for the high dimensional and a large number of data requires high computational cost, and the covariance matrix in likelihood becomes unstable. This paper introduces Kernel Bayesian ART (KBA) and ARTMAP (KBAM) by integrating Kernel Bayes' Rule (KBR) and Correntropy Induced Metric (CIM) to Bayesian ART (BA) and ARTMAP (BAM), respectively, while maintaining the properties of BA and BAM. The kernel frameworks in KBA and KBAM are able to avoid the curse of dimensionality. In addition, the covariance-free Bayesian computation by KBR provides the efficient and stable computational capability to KBA and KBAM. Furthermore, Correntropy-based similarity measurement allows improving the noise reduction ability even in the high dimensional space. The simulation experiments show that KBA performs an outstanding self-organizing capability than BA, and KBAM provides the superior classification ability than BAM, respectively.

Maladaptive spinal plasticity opposes spinal learning and recovery in spinal cord injury

Synaptic plasticity within the spinal cord has great potential to facilitate recovery of function after spinal cord injury (SCI). Spinal plasticity can be induced in an activity-dependent manner even without input from the brain after complete SCI. A mechanistic basis for these effects is provided by research demonstrating that spinal synapses have many of the same plasticity mechanisms that are known to underlie learning and memory in the brain. In addition, the lumbar spinal cord can sustain several forms of learning and memory, including limb-position training. However, not all spinal plasticity promotes recovery of function. Central sensitization of nociceptive (pain) pathways in the spinal cord may emerge in response to various noxious inputs, demonstrating that plasticity within the spinal cord may contribute to maladaptive pain states. In this review we discuss interactions between adaptive and maladaptive forms of activity-dependent plasticity in the spinal cord below the level of SCI. The literature demonstrates that activity-dependent plasticity within the spinal cord must be carefully tuned to promote adaptive spinal training. Prior work from our group has shown that stimulation that is delivered in a limb position-dependent manner or on a fixed interval can induce adaptive plasticity that promotes future spinal cord learning and reduces nociceptive hyper-reactivity. On the other hand, stimulation that is delivered in an unsynchronized fashion, such as randomized electrical stimulation or peripheral skin injuries, can generate maladaptive spinal plasticity that undermines future spinal cord learning, reduces recovery of locomotor function, and promotes nociceptive hyper-reactivity after SCI. We review these basic phenomena, how these findings relate to the broader spinal plasticity literature, discuss the cellular and molecular mechanisms, and finally discuss implications of these and other findings for improved rehabilitative therapies after SCI.

Changing trends in plastic surgery training

Directory of Open Access Journals (Sweden)

Ramesh Kumar Sharma

2014-01-01

Full Text Available Background: The currently available training models are being put to scrutiny in India today, both by the residents and the teachers. Plastic surgery specialty was created primarily for reconstructive purposes but the society always perceived it from a cosmetic angle, particularly in the post second world war era. As a result, there is a need to redefine the goals of plastic surgery training in the present times so that the plastic surgeon is "future ready" to meet the needs of society and the market forces. Materials and Methods: The author has reviewed the currently available literature on plastic surgery training from India and the western countries. An attempt has been made to study opinions from the teachers and the trainees. The modules currently available in India and abroad have been analyzed and a suggestion has been made for drafting training programs that would meet the demands of the society as well as prepare the resident both for the aesthetic and reconstructive practice. Conclusions: The plastic surgery training needs to be more vibrant and in tune with the changing times. While maintaining its core nature, the current predominantly reconstructive modules need to incorporate the aesthetic content. The evaluation should be both knowledge and competence based. The teachers need to be educated in the various teaching methods that are more applicable to grown up residents. There is a need to find ways to attract talented people in the academic plastic surgery.

Shock-absorbing materials and structures can be used as part of the transport container structure or of the truck equipment. An extensive survey of the literature has provided much information. Investigation has been made to define the required experimental procedures necessary to measure the misssing material properties. Three codes had been selected: EURDYN, MARC-CDC and SAMCEF. For code evaluation, a schematic container model has been considered to serve as a benchmark for the evaluation of plastic deformation. For the shock-calculation, the container falls from a height of 9 meters along the direction of its cylinder axis on an unyielded flat surface. The EURDYN computer code, has been selected first as it is especially designed to handle dynamic problems, preferably plastic ones. Indeed, EURDYN uses an explicit integration scheme versus time, which makes it quite efficient to run short deformation processes such as absorber collapses. The SAMCEF computer code could not readily calculate the benchmark, also a visco-plastic flow model has been added to it. The MARC computer code was supposed to be a candidate to run shock-calculation but extensive computing time and engineering efforts would be required, it was replaced by the PLEXUS code. The results obtained using the SAMCEF programme confirm those obtained with EURDYN. The PLEXUS results are in between. The proposed benchmark calculation is at the border of the capabilities of the most advanced computer codes for plastic-dynamic calculations. Indeed, a complex energy absorption process seems to take place in a narrow region, moving versus time, where very large shape inversions occur. That requires an accurate modelling of the system in the deformed regions and a skilful choice of the numerical parameters of the computer run. The three tested codes gave qualitatively consistent results and confirm some scarce experimental results

Are functional fillers improving environmental behavior of plastics? A review on LCA studies.

The use of functional fillers can be advantageous in terms of cost reduction and improved properties in plastics. There are many types of fillers used in industry, organic and inorganic, with a wide application area. As a response to the growing concerns about environmental damage that plastics cause, recently fillers have started to be considered as a way to reduce it by decreasing the need for petrochemical resources. Life cycle assessment (LCA) is identified as a proper tool to evaluate potential environmental impacts of products or systems. Therefore, in this study, the literature regarding LCA of plastics with functional fillers was reviewed in order to see if the use of fillers in plastics could be environmentally helpful. It was interesting to find out that environmental impacts of functional fillers in plastics had not been studied too often, especially in the case of inorganic fillers. Therefore, a gap in the literature was identified for the future works. Results of the study showed that, although there were not many and some differences exist among the LCA studies, the use of fillers in plastics industry may help to reduce environmental emissions. In addition, how LCA methodology was applied to these materials was also investigated. Copyright © 2018 Elsevier B.V. All rights reserved.

The role of arts activities in developing resilience and mental wellbeing in children and young people a rapid review of the literature.

Zarobe, Leyre; Bungay, Hilary

2017-11-01

This rapid review explores the role of arts activities in promoting the mental wellbeing and resilience of children and young people aged between 11 and 18 years. A systematic search of the literature was undertaken across 18 databases; no date limit was set on publication. Search terms included a range of creative activities: music, dance, singing, drama and visual arts; these were combined with terms linked to aspects of mental health, emotional wellbeing and resilience. Only studies related to activities that took place within community settings and those related to extracurricular activities based within schools were included. Following the application of inclusion and exclusion criteria, eight papers were included in the review. The interventions used in the studies were diverse and the research was heterogeneous; therefore, narrative synthesis of the results was conducted. The findings from the studies are considered in terms of the contribution the activities make to building resilience of children and young people. It was found that participating in arts activities can have a positive effect on self-confidence, self-esteem, relationship building and a sense of belonging, qualities which have been associated with resilience and mental wellbeing. Although the research evidence is limited, there is some support for providing structured group arts activities to help build resilience and contribute to positive mental wellbeing of children and young people.

Robotic-Assisted Unicompartmental Knee Arthroplasty: State-of-the Art and Review of the Literature.

Christ, Alexander B; Pearle, Andrew D; Mayman, David J; Haas, Steven B

2018-03-16

Unicompartmental knee arthroplasty is a successful treatment for unicompartmental knee osteoarthritis that has lower complication rates, faster recovery, and a more natural feeling knee compared to total knee arthroplasty. However, long-term survival has been a persistent concern. As more surgeon-controlled variables have been linked to survival, interest in robotic-assisted surgery has continued to grow. A review and synthesis of the literature on the subject of robotic-assisted unicompartmental knee arthroplasty was performed. We present the driving factors behind the development of robotic-assisted techniques in unicompartmental knee arthroplasty and the current state-of-the art. The ability of surgeons to achieve intraoperative targets with robotic assistance and the outcomes of robotic-assisted surgery are also described. Robotic-assisted surgery has become increasingly popular in unicompartmental knee arthroplasty, as it allows surgeons to more accurately and reproducibly plan and achieve operative targets during surgery. Cost remains a concern, and it remains to be seen whether robotic-assisted surgery will improve long-term survivorship after unicompartmental knee arthroplasty. Copyright © 2018 Elsevier Inc.

How does the brain mediate visual artistic creativity? Here we studied behavioral and neural changes in drawing and painting students compared to students who did not study art. We investigated three aspects of cognition vital to many visual artists: creative cognition, perception, and perception-to-action. We found that the art students became more creative via the reorganization of prefrontal white matter but did not find any significant changes in perceptual ability or related neural activity in the art students relative to the control group. Moreover, the art students improved in their ability to sketch human figures from observation, and multivariate patterns of cortical and cerebellar activity evoked by this drawing task became increasingly separable between art and non-art students. Our findings suggest that the emergence of visual artistic skills is supported by plasticity in neural pathways that enable creative cognition and mediate perceptuomotor integration.

Colliding Worlds - How Cutting-Edge Science is Redefining Contemporary Art

CERN Multimedia

CERN. Geneva

2014-01-01

There is a quiet revolution going on in the world of art, a new avant garde pushing the boundaries farther than ever before. These are artists who work together with scientists to make extraordinary creations that may well change the world as we know it. From designer butterflies to plastic surgery as performance theatre, from rabbits that glow in the dark to seeing sound and sculpting data - in my talk I will introduce this brave new world. What are some of the many sorts of art that spring from the interplay between art and science? How did this interaction begin and where is it going in the 21st century? How are concepts such as art and aesthetics being redefined? Are there similarities between the creative processes of artists and scientists and if so, what? These are some of the questions I will explore while looking into the exciting new art movement which I call artsci.

Role of Plastics on Human Health.

Kumar, Pramod

2018-05-01

Plastics, currently the universal workhorse materials of modern economy, because of their low cost and varied functional properties are posing serious threat to environment and consumer's health in many direct and indirect ways. Rising concern about the impact of plastics on environment and human health, has forced the industry to look for alternatives. This review studies current understanding of benefits and concerns surrounding use of plastics, reviews literature about health effects in humans and discusses the current state of evidence, as well as future research trends. There is increasing concern regarding additives in plastics to which most people are exposed, such as phthalates, bisphenol A or polybrominated diphenyl ethers (PBDE), and their detection in humans, leading to harmful impact on health. The studies are divided, among many other issues on the fact of considering these additives as carcinogens or toxicants, but there is a consensus that these chemicals have the ability to alter the endocrine system. Human data are limited compared to large body of experimental evidence documenting reproductive or developmental toxicity in relation to these compounds in animals. The concentrations of these additives in young children, a segment particularly sensitive to exogenous insults, are typically higher, indicating the need to decrease exposure to these compounds. The rapid increase in usage of plastics and increased awareness about its health hazard has lent urgency to the whole issue.

Selecting aesthetic gynecologic procedures for plastic surgeons: a review of target methodology.

2013-04-01

The objective of this article was to assist cosmetic-plastic surgeons in selecting aesthetic cosmetic gynecologic-plastic surgical interventions. Target methodological analyses of pertinent evidence-based scientific papers and anecdotal information linked to surgical techniques for cosmetic-plastic female external genitalia were examined. A search of the existing literature from 1900 through June 2011 was performed by utilizing electronic and manual databases. A total of 87 articles related to cosmetic-plastic gynecologic surgeries were identified in peer-review journals. Anecdotal information was identified in three sources (Barwijuk, Obstet Gynecol J 9(3):2178-2179, 2011; Benson, 5th annual congress on aesthetic vaginal surgery, Tucson, AZ, USA, November 14-15, 2010; Scheinberg, Obstet Gynecol J 9(3):2191, 2011). Among those articles on cosmetic-plastic gynecologic surgical technique that were reviewed, three articles met the criteria for evidence-based medicine level II, one article was level II-1 and two papers were level II-2. The remaining papers were classified as level III. The pertinent 25 papers met the inclusion criteria and were analyzed. There was no documentation on the safety and effectiveness of cosmetic-plastic gynecologic procedures in the scientific literature. All published surgical interventions are not suitable for a cosmetic-plastic practice. The absence of documentation on safety and effectiveness related to cosmetic-plastic gynecologic procedures prevents the establishment of a standard of practice. Traditional gynecologic surgical procedures cannot be labeled and used as cosmetic-plastic procedures, it is a deceptive practice. Obtaining legal trademarks on traditional gynecologic procedures and creating a business model that tries to control clinical-scientific knowledge dissemination is unethical. This journal requires that authors assign a level of evidence to each article. For a full description of these Evidence-Based Medicine ratings

Plastic pollution in islands of the Atlantic Ocean.

Marine plastic pollution is present in all oceans, including remote oceanic islands. Despite the increasing number of articles on plastic pollution in the last years, there is still a lack of studies in islands, that are biodiversity hotspots when compared to the surrounding ocean, and even other recognized highly biodiverse marine environments. Articles published in the peer reviewed literature (N = 20) were analysed according to the presence of macro (>5 mm) and microplastics (plastics associated with variables such as position of the beach in relation to wind and currents. Very few studies have analysed plastics colonization by organisms or the identification of persistent organic pollutants (POPs). Islands of the North/South Atlantic and Caribbean Sea were influenced by different sources of macroplastics, being marine-based sources (i.e., fishing activities) predominant in the Atlantic Ocean basin. On the other hand, in the Caribbean Sea, land-based sources were more common. Copyright © 2018 Elsevier Ltd. All rights reserved.

Jensen, A; Bonde, L O

2018-04-01

This literature review aims to illustrate the variety and multitude of studies showing that participation in arts activities and clinical arts interventions can be beneficial for citizens with mental and physical health problems. The article is focused on mental health benefits because this is an emerging field in the Nordic countries where evidence is demanded from national health agencies that face an increasing number of citizens with poor mental health and a need for non-medical interventions and programmes. A total of 20 articles of interest were drawn from a wider literature review. Studies were identified through the search engines: Cochrane Library, Primo, Ebscohost, ProQuest, Web of Science, CINAHL, PsycINFO, PubMed and Design and Applied Arts Index. Search words included the following: arts engagement + health/hospital/recovery, arts + hospital/evidence/wellbeing, evidence-based health practice, participatory arts for wellbeing, health + poetry/literature/dance/singing/music/community arts, arts health cost-effectiveness and creative art or creative activity + health/hospital/recovery/mental health. The inclusion criteria for studies were (1) peer review and (2) empirical data. The studies document that participation in activities in a spectrum from clinical arts interventions to non-clinical participatory arts programmes is beneficial and an effective way of using engagement in the arts to promote holistic approaches with health benefits. Engagement in specially designed arts activities or arts therapies can reduce physical symptoms and improve mental health issues. Based on the growing evidence of the arts as a tool for enhancing mental health wellbeing, and in line with the global challenges in health, we suggest that participatory arts activities and clinical arts interventions are made more widely available in health and social settings. It is well-documented that such activities can be used as non-medical interventions to promote public health and

Threat of plastic pollution to seabirds is global, pervasive, and increasing.

Plastic pollution in the ocean is a global concern; concentrations reach 580,000 pieces per km(2) and production is increasing exponentially. Although a large number of empirical studies provide emerging evidence of impacts to wildlife, there has been little systematic assessment of risk. We performed a spatial risk analysis using predicted debris distributions and ranges for 186 seabird species to model debris exposure. We adjusted the model using published data on plastic ingestion by seabirds. Eighty of 135 (59%) species with studies reported in the literature between 1962 and 2012 had ingested plastic, and, within those studies, on average 29% of individuals had plastic in their gut. Standardizing the data for time and species, we estimate the ingestion rate would reach 90% of individuals if these studies were conducted today. Using these results from the literature, we tuned our risk model and were able to capture 71% of the variation in plastic ingestion based on a model including exposure, time, study method, and body size. We used this tuned model to predict risk across seabird species at the global scale. The highest area of expected impact occurs at the Southern Ocean boundary in the Tasman Sea between Australia and New Zealand, which contrasts with previous work identifying this area as having low anthropogenic pressures and concentrations of marine debris. We predict that plastics ingestion is increasing in seabirds, that it will reach 99% of all species by 2050, and that effective waste management can reduce this threat.

Reynolds, Chevonne; Ryan, Peter G

2018-01-01

Despite a large literature on the impacts of micro-plastic pollution in marine ecosystems, very little research has focused on these pollutants in freshwater ecosystems. Recently, however, a few studies have demonstrated that micro-plastic pollutants are ingested by freshwater taxa, including birds. To explore this potential environmental threat in African freshwater systems we quantified micro-plastic pollutants in the faeces and feather brushings of seven southern African duck species. We analysed 283 faecal samples and 408 feather brushings, and found that 5% of faecal samples and 10% of feather samples contained micro-plastic fibres. The presence and abundance of micro-fibres differed between sampling sites, with significantly higher amounts recorded for the site that received effluent from a sewage treatment facility. Additionally, micro-fibre presence differed across duck species, indicating that foraging behaviour affects plastic ingestion. Our study confirms that African freshwater ecosystems and the biodiversity they support are under threat from micro-plastic contamination. Copyright © 2017 Elsevier Ltd. All rights reserved.

Occupational Health and the Visual Arts: An Introduction.

Science.gov (United States)

Hinkamp, David; McCann, Michael; Babin, Angela R

2017-09-01

Occupational hazards in the visual arts often involve hazardous materials, though hazardous equipment and hazardous work conditions can also be found. Occupational health professionals are familiar with most of these hazards and are particularly qualified to contribute clinical and preventive expertise to these issues. Articles illustrating visual arts health issues were sought and reviewed. Literature sources included medical databases, unindexed art-health publications, and popular press articles. Few medical articles examine health issues in the visuals arts directly, but exposures to pigments, solvents, and other hazards found in the visual arts are well described. The hierarchy of controls is an appropriate model for controlling hazards and promoting safer visual art workplaces. The health and safety of those working in the visual arts can benefit from the occupational health approach. Sources of further information are available.

Many studies have been published on vegetable oil use in diesel engines. The different authors unanimously acknowledge the potential and merits of this renewable fuel. Typically, Straight Vegetable Oils (SVOs) produced locally on a small scale, have proven to be easy to produce with very little environmental impact. However, as their physico-chemical characteristics differ from those of diesel oil, their use in diesel engines can lead to a certain number of technical problems over time. In bibliography, there is substantial disagreement between authors regarding the advanced phenomena linked to this problems and the recommended solutions. Some of these publications treat options individually without any real comparison between them. Another observation is that the literature rarely tackles problems linked to vegetable oil quality. This paper sets out to review the state of the art for SVO use as fuel in diesel engines, based on a bibliographic study (literature review). The first section of the document examines the influence of the type and quality of vegetable oils for fuel use in diesel engines. The second section discusses the advantages and disadvantages of two options recommended for SVO use in diesel engines: dual fuelling and blending with diesel fuel. (author)

Developing a nursing personnel policy to address body art using an evidence-based model.

Dorwart, Shawna D; Kuntz, Sandra W; Armstrong, Myrna L

2010-12-01

An increase in the prevalence of body art as a form of self-expression has motivated health care organizations to develop policies addressing nursing personnel's body art. A systematic review of literature on body art was completed and a telephone survey of 15 hospitals was conducted to query existing policy statements addressing nursing personnel's body art. The literature established no prevalence of body art among nurses or effect of nurses' body art. Of the 13 hospitals (86%) that shared their policy on body art, none provided a rationale or references to support their existing policies. A lack of published evidence identifying the effect of body art among nurses shifts the burden of determining care outcomes to the leadership of individual hospitals. Further research on patients' perception of nursing personnel with visible body art, using an evidence-based model, is recommended. Copyright 2010, SLACK Incorporated.

How do astronomical methods make it possible to calculate dates and times for Vincent van Gogh's night-sky paintings? Why is there a blood-red sky in Edvard Munch's The Scream? On what dates did Ansel Adams create his moonrise photographs in Yosemite? How can the 18.6-year cycle of the lunar nodes and the Moon's declination on the night of August 29-30, 1857, explain a long-standing mystery about Abraham Lincoln's honesty in the murder case known as the almanac trial? Why is a bright star described in Act 1, Scene 1, of Hamlet? To answer questions like these, our Texas State group has published a series of articles over the last two decades, applying astronomy to art, history, and literature.

Fifty Years of Innovation in Plastic Surgery

Directory of Open Access Journals (Sweden)

Richard M Kwasnicki

2016-03-01

Full Text Available BackgroundInnovation has molded the current landscape of plastic surgery. However, documentation of this process only exists scattered throughout the literature as individual articles. The few attempts made to profile innovation in plastic surgery have been narrative, and therefore qualitative and inherently biased. Through the implementation of a novel innovation metric, this work aims to identify and characterise the most prevalent innovations in plastic surgery over the last 50 years.MethodsPatents and publications related to plastic surgery (1960 to 2010 were retrieved from patent and MEDLINE databases, respectively. The most active patent codes were identified and grouped into technology areas, which were subsequently plotted graphically against publication data. Expert-derived technologies outside of the top performing patents areas were additionally explored.ResultsBetween 1960 and 2010, 4,651 patents and 43,118 publications related to plastic surgery were identified. The most active patent codes were grouped under reconstructive prostheses, implants, instruments, non-invasive techniques, and tissue engineering. Of these areas and other expert-derived technologies, those currently undergoing growth include surgical instruments, implants, non-invasive practices, transplantation and breast surgery. Innovations related to microvascular surgery, liposuction, tissue engineering, lasers and prostheses have all plateaued.ConclusionsThe application of a novel metric for evaluating innovation quantitatively outlines the natural history of technologies fundamental to the evolution of plastic surgery. Analysis of current innovation trends provides some insight into which technology domains are the most active.

Plastic recycling in the Nordics: A value chain market analysis.

Milios, Leonidas; Holm Christensen, Lena; McKinnon, David; Christensen, Camilla; Rasch, Marie Katrine; Hallstrøm Eriksen, Mikael

2018-06-01

There is low utilisation of plastic waste in the Nordic region and only a fraction of plastic materials go back into production processes through reuse and recycling practices. This paper aims to increase knowledge concerning factors that inhibit demand for recycled plastics, and to identify critical barriers for plastic recycling across the regional plastics value chain. A literature review and targeted interviews with key actors across the plastics value chain enabled the mapping of interactions between the major actors and identified hotspots that act as barriers to the flow of plastic materials. Barriers identified include the lack of both supply and demand of recycled plastic and are mainly attributed to the fragmented market of secondary materials. The main hotspots identified are the low demand due to price considerations, insufficient traceability and transparency in value chain transactions, and general design deficiencies in the recyclability of products. Value chain coordination is considered as the most important intervention by the interviewees, followed by the need for increased investment in innovation and technology development. Complementary measures that could counteract the identified barriers include public procurement for resource efficiency, ban on the incineration of recyclable materials, and specifications on the design of plastic products for reducing the number of different polymers, and the number and usage of additives.

2016-12-01

Art is a product of human creativity; it is a superior skill that can be learned by study, practice and observation. Modern neuroscience and neuroimaging enable study of the processes during artistic performance. Creative people have less marked hemispheric dominance. It was found that the right hemisphere is specialized for metaphoric thinking, playfulness, solution finding and synthesizing, it is the center of visualization, imagination and conceptualization, but the left hemisphere is still needed for artistic work to achieve balance. A specific functional organization of brain areas was found during visual art activities. Marked hemispheric dominance and area specialization is also very prominent for music perception. Brain is capable of making new connections, activating new pathways and unmasking secondary roads, it is "plastic". Music is a strong stimulus for neuroplasticity. fMRI studies have shown reorganization of motor and auditory cortex in professional musicians. Other studies showed the changes in neurotransmitter and hormone serum levels in correlation to music. The most prominent connection between music and enhancement of performance or changing of neuropsychological activity was shown by studies involving Mozart's music from which the theory of "The Mozart Effect" was derived. Results of numerous studies showed that listening to music can improve cognition, motor skills and recovery after brain injury. In the field of visual art, brain lesion can lead to the visuospatial neglect, loss of details and significant impairment of artistic work while the lesions affecting the left hemisphere reveal new artistic dimensions, disinhibit the right hemisphere, work is more spontaneous and emotional with the gain of artistic quality. All kinds of arts (music, painting, dancing...) stimulate the brain. They should be part of treatment processes. Work of many artists is an excellent example for the interweaving the neurology and arts.

[Personal motif in art].

Science.gov (United States)

Gerevich, József

2015-01-01

One of the basic questions of the art psychology is whether a personal motif is to be found behind works of art and if so, how openly or indirectly it appears in the work itself. Analysis of examples and documents from the fine arts and literature allow us to conclude that the personal motif that can be identified by the viewer through symbols, at times easily at others with more difficulty, gives an emotional plus to the artistic product. The personal motif may be found in traumatic experiences, in communication to the model or with other emotionally important persons (mourning, disappointment, revenge, hatred, rivalry, revolt etc.), in self-searching, or self-analysis. The emotions are expressed in artistic activity either directly or indirectly. The intention nourished by the artist's identity (Kunstwollen) may stand in the way of spontaneous self-expression, channelling it into hidden paths. Under the influence of certain circumstances, the artist may arouse in the viewer, consciously or unconsciously, an illusionary, misleading image of himself. An examination of the personal motif is one of the important research areas of art therapy.

Art provides an integrating function between the 'upper' and 'lower' centers of the human psyche. The nature of this function can be made more specific through the triune model of the brain. The evolution of the fine arts - painting, drawing, architecture, sculpture, literature, music, dance, and drama, plus cinema and mathematics-as-a-fine-art - are examined in the context of their probable stimulations by space exploration: near term and long term.

Ways of Viewing Pictorial Plasticity

Full Text Available The plastic effect is historically used to denote various forms of stereopsis. The vivid impression of depth often associated with binocular stereopsis can also be achieved in other ways, for example, using a synopter. Accounts of this go back over a hundred years. These ways of viewing all aim to diminish sensorial evidence that the picture is physically flat. Although various viewing modes have been proposed in the literature, their effects have never been compared. In the current study, we compared three viewing modes: monocular blur, synoptic viewing, and free viewing (using a placebo synopter. By designing a physical embodiment that was indistinguishable for the three experimental conditions, we kept observers naïve with respect to the differences between them; 197 observers participated in an experiment where the three viewing modes were compared by performing a rating task. Results indicate that synoptic viewing causes the largest plastic effect. Monocular blur scores lower than synoptic viewing but is still rated significantly higher than the baseline conditions. The results strengthen the idea that synoptic viewing is not due to a placebo effect. Furthermore, monocular blur has been verified for the first time as a way of experiencing the plastic effect, although the effect is smaller than synoptic viewing. We discuss the results with respect to the theoretical basis for the plastic effect. We show that current theories are not described with sufficient details to explain the differences we found.

The aim is to compare plastic deformation capacities of flexure-controlled reinforced concrete members, as predicted by the Italian Seismic Code, Eurocode 8 and FEMA356. For completeness, recent studies in the literature are also referred to. The comparison is pursued in context with a nonlinear static analysis run on 2D frame structures. This allows to assess whether and to which extent plastic deformation capacities may be affected by variations in those quantities, such as shear span and/or axial load, depending on which plastic deformation capacities are generally given

Hermabessiere, Ludovic; Dehaut, Alexandre; Paul-Pont, Ika; Lacroix, Camille; Jezequel, Ronan; Soudant, Philippe; Duflos, Guillaume

2017-09-01

Plastics debris, especially microplastics, have been found worldwide in all marine compartments. Much research has been carried out on adsorbed pollutants on plastic pieces and hydrophobic organic compounds (HOC) associated with microplastics. However, only a few studies have focused on plastic additives. These chemicals are incorporated into plastics from which they can leach out as most of them are not chemically bound. As a consequence of plastic accumulation and fragmentation in oceans, plastic additives could represent an increasing ecotoxicological risk for marine organisms. The present work reviewed the main class of plastic additives identified in the literature, their occurrence in the marine environment, as well as their effects on and transfers to marine organisms. This work identified polybrominated diphenyl ethers (PBDE), phthalates, nonylphenols (NP), bisphenol A (BPA) and antioxidants as the most common plastic additives found in marine environments. Moreover, transfer of these plastic additives to marine organisms has been demonstrated both in laboratory and field studies. Upcoming research focusing on the toxicity of microplastics should include these plastic additives as potential hazards for marine organisms, and a greater focus on the transport and fate of plastic additives is now required considering that these chemicals may easily leach out from plastics.

Cheryl V. Elhammoumi

2017-05-01

Full Text Available Background: Nursing research has concentrated on empirical knowing with little focus on aesthetic knowing. Evidence from the literature suggests that using visual art in nursing education enhances both clinical observation skills and interpersonal skills. The purpose of this review was to explore how visual art has been used in baccalaureate nursing education. Methods: Of 712 records, 13 studies met the criteria of art, nursing and education among baccalaureate nursing students published in English. Results: Three quantitative studies demonstrated statistical significance between nursing students who participated in arts-based learning compared to nursing students who received traditional learning. Findings included improved recall, increased critical thinking and enhanced emotional investment. Themes identified in 10 qualitative studies included spirituality as role enhancement, empathy, and creativity. Conclusion: Visual arts-based learning in pre-licensure curriculum complements traditional content. It supports spirituality as role enhancement in nurse training. Visual art has been successfully used to enhance both critical thinking and interpersonal relations. Nursing students may experience a greater intra-connectedness that results in better inter-connectedness with patients and colleagues. Incorporating visual arts into pre-licensure curriculums is necessary to nurture holistic nursing practice.

Global change and the evolution of phenotypic plasticity in plants.

Science.gov (United States)

Matesanz, Silvia; Gianoli, Ernesto; Valladares, Fernando

2010-09-01

Global change drivers create new environmental scenarios and selective pressures, affecting plant species in various interacting ways. Plants respond with changes in phenology, physiology, and reproduction, with consequences for biotic interactions and community composition. We review information on phenotypic plasticity, a primary means by which plants cope with global change scenarios, recommending promising approaches for investigating the evolution of plasticity and describing constraints to its evolution. We discuss the important but largely ignored role of phenotypic plasticity in range shifts and review the extensive literature on invasive species as models of evolutionary change in novel environments. Plasticity can play a role both in the short-term response of plant populations to global change as well as in their long-term fate through the maintenance of genetic variation. In new environmental conditions, plasticity of certain functional traits may be beneficial (i.e., the plastic response is accompanied by a fitness advantage) and thus selected for. Plasticity can also be relevant in the establishment and persistence of plants in novel environments that are crucial for populations at the colonizing edge in range shifts induced by climate change. Experimental studies show taxonomically widespread plastic responses to global change drivers in many functional traits, though there is a lack of empirical support for many theoretical models on the evolution of phenotypic plasticity. Future studies should assess the adaptive value and evolutionary potential of plasticity under complex, realistic global change scenarios. Promising tools include resurrection protocols and artificial selection experiments. © 2010 New York Academy of Sciences.

Martial arts as sport and therapy.

2007-03-01

The term Martial Arts is often used as general phrase to describe many of the combat arts, which have developed in eastern cultures over the past millennium. This paper reviews the Martial Arts from the original context of a trio of life skills. This trio includes the healing arts such as acupuncture, the self-exploration arts such as yoga, and the vital life skills such as meditation. As Martial Arts suggests the waging of combat, the origins of the most common combat arts are reviewed, with an overview of the difference between the hard and the soft styles. The arts developed not only in the eastern, but also in all parts of the world, with references of these types of combats arts in the writings of the ancient Egyptians and Greeks. In modern times, the combat arts are performed for both exercise and sport. A review of the injuries that occur, and the health benefits that might be expected are discussed. A review of the medical literature that demonstrates some of these health benefits is included, with Tai Chi Chuan as the most studied of these. The health benefits discussed include strengthen and self-efficacy of the elderly, reduced falls, increased exercise capacity, and benefits to the immune system and autonomic nervous system. The paper emphasized the breadth of the Martial Arts and the import of these to the sports and health community.

Disclosure of Financial Conflicts of Interest in Plastic and Reconstructive Surgery.

Science.gov (United States)

Luce, Edward A; Jackman, Carye A

2017-09-01

Recent articles in the scientific literature have expressed concerns about financial conflicts of interest in the profession of medicine in general and the specialty of plastic surgery in particular. Disclosure of financial ties to industry has been regarded as an address of a possible bias. The policies of medical journals places responsibility on authors for self-reporting of financial conflicts of interest, yet underreporting of conflicts of interest has occurred. The investigative hypothesis was that authors in the plastic surgery literature, in particular, Plastic and Reconstructive Surgery, underreported financial conflicts of interest. A review of articles published in Plastic and Reconstructive Surgery from July of 2015 through April of 2016 for author disclosures was accomplished. The disclosure statements were compared to the information available in the Open Payments database for 2015. The lack of disclosure on the part of an author, when present, was individually examined for relevance of the corporate conflicts of interest to the subject matter of the involved article. A total of 302 articles authored by 1262 individuals were reviewed. One hundred thirty-nine (45.5 percent) had neither a disclosed nor an actual conflict of interest. In 61 articles (20.2 percent), one or more authors disclosed; 105 articles (34.8 percent) did not provide disclosure of a financial conflict of interest. In assessment of relevance, 10 undisclosed conflicts of interest (9.5 percent) were determined relevant, and one-third of that total were non-plastic surgeons. Nondisclosure of financial conflicts of interest is common, but only a small minority pose a potential for harm from bias.

Plastic Deformation of Pressured Metallic Glass

Directory of Open Access Journals (Sweden)

Yun Cheng

2017-11-01

Full Text Available Although pressured metallic glass (MG has been reported in the literature; there are few studies focusing on pressure effects on the structure; dynamics and its plastic deformation. In this paper; we report on and characterize; via molecular dynamics simulation, the structure and dynamics heterogeneity of pressured MGs, and explore a causal link between local structures and plastic deformation mechanism of pressured glass. The results exhibit that the dynamical heterogeneity of metallic liquid is more pronounced at high pressure, while the MGs were less fragile after the release of external pressure, reflected by the non-Gaussian parameter (NGP. High pressure glass shows better plastic deformation; and the local strain zone distributed more uniformly than of in normal glass. Further research indicates that although the number of icosahedrons in pressured glass was much larger than that in normal glass, while the interpenetrating connections of icosahedra (ICOI exhibited spatial correlations were rather poor; In addition, the number of ‘fast’ atoms indexed by the atoms’ moving distance is larger than that in normal glass; leading to the sharp decreasing in number of icosahedrons during deformation. An uniform distribution of ‘fast’ atoms also contributed to better plastic deformation ability in the pressured glass. These findings may suggest a link between the deformation and destruction of icosahedra with short-range order.

Fine pitch thermosonic wire bonding: analysis of state-of-the-art manufacturing capability

Cavasin, Daniel

1995-09-01

A comprehensive process characterization was performed at the Motorola plastic package assembly site in Selangor, Malaysia, to document the current fine pitch wire bond process capability, using state-of-the-art equipment, in an actual manufacturing environment. Two machines, representing the latest technology from two separate manufacturers, were operated one shift per day for five days, bonding a 132 lead Plastic Quad Flat Pack. Using a test device specifically designed for fine pitch wire bonding, the bonding programs were alternated between 107 micrometers and 92 micrometers pad pitch, running each pitch for a total of 1600 units per machine. Wire, capillary type, and related materials were standardized and commercially available. A video metrology measurement system, with a demonstrated six sigma repeatability band width of 0.51 micrometers , was utilized to measure the bonded units for bond dimensions and placement. Standard Quality Assurance (QA) metrics were also performed. Results indicate that state-of-the-art thermosonic wire bonding can achieve acceptable assembly yields at these fine pad pitches.

Prediction of elastic-plastic response of structural elements subjected to cyclic loading

International Nuclear Information System (INIS)

El Haddad, M.H.; Samaan, S.

1985-01-01

A simplified elastic-plastic analysis is developed to predict stress strain and force deformation response of structural metallic elements subjected to irregular cyclic loadings. In this analysis a simple elastic-plastic method for predicting the skeleton force deformation curve is developed. In this method, elastic and fully plastic solutions are first obtained for unknown quantities, such as deflection or local strains. Elastic and fully plastic contributions are then combined to obtain an elastic-plastic solution. The skeleton curve is doubled to establish the shape of the hysteresis loop. The complete force deformation response can therefore be simulated through reversal by reversal in accordance with hysteresis looping and material memory. Several examples of structural elements with various cross sections made from various materials and subjected to irregular cyclic loadings, are analysed. A close agreement is obtained between experimental results found in the literature and present predictions. (orig.)

Acupuncture is widely applied for treatment of various neurological disorders. This manuscript will review the preclinical evidence of acupuncture in mediating neural plasticity, the mechanisms involved. We searched acupuncture, plasticity, and other potential related words at the following sites: PubMed, EMBASE, Cochrane Library, Chinese National Knowledge Infrastructure (CNKI), and VIP information data base. The following keywords were used: acupuncture, electroacupuncture, plasticity, neural plasticity, neuroplasticity, neurogenesis, neuroblast, stem cell, progenitor cell, BrdU, synapse, synapse structure, synaptogenesis, axon, axon regeneration, synaptic plasticity, LTP, LTD, neurotrophin, neurotrophic factor, BDNF, GDNF, VEGF, bFGF, EGF, NT-3, NT-4, NT-5, p75NTR, neurotransmitter, acetylcholine, norepinephrine, noradrenaline, dopamine, monamine. We assessed the effects of acupuncture on plasticity under pathological conditions in this review. Relevant references were reviewed and presented to reflect the effects of acupuncture on neural plasticity. The acquired literatures mainly focused on neurogenesis, alterations of synapses, neurotrophins (NTs), and neurotranimitters. Acupuncture methods mentioned in this article include manual acupuncture and electroacupuncture. The cumulative evidences demonstrated that acupuncture could induce neural plasticity in rodents exposed to cerebral ischemia. Neural plasticity mediated by acupuncture in other neural disorders, such as Alzheimer's disease, Parkinson's disease, and depression, were also investigated and there is evidence of positive role of acupuncture induced plasticity in these disorders as well. Mediation of neural plasticity by acupuncture is likely associated with its modulation on NTs and neurotransmitters. The exact mechanisms underlying acupuncture's effects on neural plasticity remain to be elucidated. Neural plasticity may be the potential bridge between acupuncture and the treatment of various

Disposal of large quantity of plastic causes land, water and air pollution etc.., so a study is conducted to recycle the plastic in concrete. This work investigates about the replacement of natural aggregate with non-biodegradable plastic aggregate made up of mixed plastic waste in concrete. Several tests are conducted such as compressive strength of cube, split tensile strength of cylinder, flexural strength test of prism to identify the properties and behavior of concrete using plastic aggregate. Replacement of fine aggregate weight by 10%, 15%, 20% with Plastic fine (PF) aggregate and for each replacement of fine aggregate 15%, 20%, 25% of coarse aggregate replacement also conducted with Plastic Coarse(PC) aggregate. In literatures reported that the addition of plastic aggregate in concrete causes the reduction of strength in concrete due to poor bonding between concrete and plastic aggregate, so addition of 0.3% of steel fiber by weight of cement in concrete is done to improve the concrete strength. Totally 60 cubes, 60 cylinders and 40 prisms are casted to identify the compressive strength, split tensile strength and flexural strength respectively. Casted specimens are tested at 7 and 28 days. The identified results from concrete using plastic aggregate are compared with conventional concrete. Result shows that reduction in mechanical properties of plastic aggregate added concrete. This reduction in strength is mainly due to poor bond strength between cement and plastic aggregate.

Embedding of reactor wastes in plastic resins

International Nuclear Information System (INIS)

1979-01-01

STEAG Kernenergie GmbH is so far the only firm commercially to condition radioactive bead ion exchange resins by embedding in polystyrene resins. The objective of the work reported here was to study and develop methods for immobilization of other reactor wastes in plastic resins. Comparison studies on high quality cement however showed favourable results for cement with respect to process safety and economy. For this reason STEAG interrupted its work in the field of resin embedding after about one year. The work carried out during this period is surveyed in this report, which includes a comprehensive literature study on reactor wastes and their solidification in plastic resins as well as on regulations with regard to radioactive waste disposal in the member states of the European Communities

The use of story, and the use of art or various arts-based techniques have become popular in a number of helping professions, including spiritual care. There remains a gap in the literature, however, in which an approach comprised of both story and art or objects is explored. This paper addresses this gap by discussing the experience, theory, benefits, and technique of combining story and art or object-based techniques for the provision of spiritual care.

International policies to reduce plastic marine pollution from single-use plastics (plastic bags and microbeads): A review.

Science.gov (United States)

Xanthos, Dirk; Walker, Tony R

2017-05-15

Marine plastic pollution has been a growing concern for decades. Single-use plastics (plastic bags and microbeads) are a significant source of this pollution. Although research outlining environmental, social, and economic impacts of marine plastic pollution is growing, few studies have examined policy and legislative tools to reduce plastic pollution, particularly single-use plastics (plastic bags and microbeads). This paper reviews current international market-based strategies and policies to reduce plastic bags and microbeads. While policies to reduce microbeads began in 2014, interventions for plastic bags began much earlier in 1991. However, few studies have documented or measured the effectiveness of these reduction strategies. Recommendations to further reduce single-use plastic marine pollution include: (i) research to evaluate effectiveness of bans and levies to ensure policies are having positive impacts on marine environments; and (ii) education and outreach to reduce consumption of plastic bags and microbeads at source.

Full Text Available The literature on EU democracy promotion is fragmented into a number of sub-literatures, and this makes it difficult to gain a comprehensive understanding of this area of EU activity. Synthesising these literatures and the different theoretical approaches that have been taken is a necessary first step to a fuller understanding of what makes EU democracy promotion work most effectively, a task that is all the more vital given the increasingly challenging global environment that democracy promotion now faces.

Plasticity and genetic adaptation mediate amphibian and reptile responses to climate change

Science.gov (United States)

Urban, Mark C; Richardson, Jonathan L; Freidenfelds, Nicole A

2014-01-01

Phenotypic plasticity and genetic adaptation are predicted to mitigate some of the negative biotic consequences of climate change. Here, we evaluate evidence for plastic and evolutionary responses to climate variation in amphibians and reptiles via a literature review and meta-analysis. We included studies that either document phenotypic changes through time or space. Plasticity had a clear and ubiquitous role in promoting phenotypic changes in response to climate variation. For adaptive evolution, we found no direct evidence for evolution of amphibians or reptiles in response to climate change over time. However, we found many studies that documented adaptive responses to climate along spatial gradients. Plasticity provided a mixture of adaptive and maladaptive responses to climate change, highlighting that plasticity frequently, but not always, could ameliorate climate change. Based on our review, we advocate for more experiments that survey genetic changes through time in response to climate change. Overall, plastic and genetic variation in amphibians and reptiles could buffer some of the formidable threats from climate change, but large uncertainties remain owing to limited data. PMID:24454550

2013-03-01

 Although the exact time of performing plastic surgery is not addressed in the medical and historical literature, it can be supposed that these surgical procedures have a long and fascinating history.  Recent excavations provided many documents regarding the application of medical instruments, surgical and even reconstructive procedures during the pre-historic and ancient periods. Actually, there is no historical definite time-zone separating general and cosmetic operations in the pre-modern time; however, historically there have been many surgeons who tried to perform reconstructive procedures during their usual medical practice. This article presents a brief look at the history of plastic surgery form the ancient to the contemporary era, with a special focus on Iran.

The Aesthetic Turn in Mental Health: Reflections on an Explorative Study into Practices in the Arts Therapies

Directory of Open Access Journals (Sweden)

Rosemarie Samaritter

2018-04-01

Full Text Available The paper will draw on materials from arts therapies literature and comments from experts’ panels to discuss some specific characteristics of the arts therapies and to investigate the role of aesthetic engagement for resilience and mental well-being. The arts increasingly find their way as interventions in mental health domains. However, explorations into the specific mechanisms that underpin the therapeutic effect of arts-based activities are still scarce. Qualitative data were collected from a thematic literature review and expert comments on meaningful working procedures in arts therapies. Analysis of multiple data sources revealed core themes and core procedures that occur across arts therapy modalities. This paper presents a practice informed model of arts-based methods in mental health that may serve as a conceptual frame of reference for arts therapists and as study material on the applicability of arts therapy interventions for specific mental health settings.

Amoatey, A. E.

2012-07-01

The levels of organochlorine pesticides (OCPs) in beached plastic resin pellets were determined with the objective of assessing the status of OCP pollution in the marine ecosystem in selected beaches in Ghana. Samples of plastic resin pellets were collected at seven beaches in Accra (namely Art centre, Sakumono, Osu castle, Labadi, Korle-Gonno, Independence Square and Tema Mighty beaches) and analyzed for organochlorine pesticides, total chlorine and extractable chlorine. The plastic pellets were subjected to Soxhlet extraction and the extracts analyzed using Gas chromatograph coupled with electron capture detector. The detected compounds were alpha-HCH, beta-HCH, gamma-HCH, delta-HCH, hexachlorobenzene, o, p' -DDE, p, p'-DDE, o,p'-DDD, o, p'-DDT, heptachlor, trans-heptachlor epoxy, trans-chlordane, trans-nanochlor, aldrin, dieldrin, endrin, alpha-endosulphan, beta-endosulphan, endosulphan sulphate and methoxychlor. Analysis of the virgin pellets recorded no organochlorine pesticides present. However, plastics pellets collected from all seven beaches were found to contain OCPs with the highest recorded on the Art Centre beach with a total concentration of 106.26 ng/g. Plastic pellets collected on the Labadi beach recorded the lowest OCPs with a concentration of 20.2 ng/g. Total chlorine and extractable organochlorine (EOCI) were also determined in the plastic resin pellets by using the Instrumental Neutron Activation Analysis (INAA). The concentrations of total chlorine analyzed by INAA were between 2.82 and 50.25 mg/kg whereas the EOCR concentrations ranged from 1.67 to 30.90 mg/kg. EOCR accounted for 48.05% of the total chlorine in plastic pellets, suggesting that chlorine in the beached pellet relatively existed as organic and are extractable. The relative proportion of known or identified organochlorines (such as HCHs, DDT s, chlordane compounds, endosulphans, HCB and methoxychlor) to the total extractable organochlorine(EOCI) was averagely 7.4% which suggested

We will examine how the humanities -- the visual arts, science fiction, poetry, music, etc. -- can be used in teaching introductory astronomy courses for non-science majors. A number of instructors have found innovative ways to show how astronomy has a deep influence on other areas of human culture and how the humanities can illuminate our students' understanding of the universe. A few astronomers are also making original contributions at the interface of astronomy and the humanities. The panel of speakers for the session will consists of: Gregory Benford (U. of California, Irvine): Using Science Fiction to Teach Astronomy: Promise and Pitfalls William Hartmann (Planetary Science Institute): Science and Art in the Classroom Andrew Fraknoi (Foothill College & A.S.P.): The Humanities in the Astronomy Classroom: Activities and Projects George Greenstein (Amherst College) will be the session moderator. Time will be set aside for brief summaries of the poster papers associated with this session and for discussion. Participants will receive a resource guide to using the humanities for astronomy teaching.

Silvestre, Jason; Zhang, Alicia; Lin, Samuel J

2016-06-01

The Plastic Surgery In-Service Training Exam is a knowledge assessment tool widely used during plastic surgery training in the United States. This study analyzed literature supporting correct answer choices to determine highest yield sources, journal publication lag, and journal impact factors. Digital syllabi of 10 consecutive Plastic Surgery In-Service Training Exam administrations (2006 to 2015) were reviewed. The most-referenced articles, journals, and textbooks were determined. Mean journal impact factor and publication lag were calculated and differences were elucidated by section. Two thousand questions and 5386 references were analyzed. From 2006 to 2015, the percentage of journal citations increased, whereas textbook references decreased (p < 0.001). Plastic and Reconstructive Surgery was cited with greatest frequency (38.5 percent), followed by Clinics in Plastic Surgery (5.6 percent), Journal of Hand Surgery (American volume) (5.1 percent), and Annals of Plastic Surgery (3.8 percent). There was a trend toward less publication lag over the study period (p = 0.05), with a mean publication lag of 9.1 ± 9.0 years for all journal articles. Mean journal impact factor was 2.3 ± 4.3 and lowest for the hand and lower extremity section (1.7 ± 2.8; p < 0.001). The highest yield textbooks were elucidated by section. Plastic surgery faculty and residents may use these data to facilitate knowledge acquisition during residency.

Plastic ingestion by fish in the Southern Hemisphere: A baseline study and review of methods.

Science.gov (United States)

Cannon, Seon M E; Lavers, Jennifer L; Figueiredo, Bianca

2016-06-15

Plastic ingestion is well documented among marine birds and sea turtles but fewer studies have investigated ingestion in fish, particularly in the Southern Hemisphere. We investigated the frequency of plastic ingestion in 21 species of fish and one species of cephalopod. The overall occurrence of plastic ingestion was 0.3%. Two micro-plastic items were recovered from the gastrointestinal tract of a single Antarctic toothfish (Dissostichus mawsoni). Ingestion rates were similar to other studies of fish conducted in both the Northern and Southern Hemispheres, however comparisons across species and locations are challenging due to the lack of consistency in the identification and classification of plastic debris. In response, we propose a standardised sampling protocol based on the available literature to provide a stronger basis for comparisons among existing and future studies of plastic ingestion in fish.

Aesthetics of the Human Image in Life and Iconography of the Ancient Philosophers in Art

Directory of Open Access Journals (Sweden)

Dorofeev, Daniil

2015-04-01

Full Text Available The acoustic and visual understanding of man is a hotly debated issue in contemporary culture. I found it important therefore to look at certain historical, cultural, aesthetical, philosophical and anthropological peculiarities of human image in Antiquity as reflected in the arts. The following aspects deserve special attention: the visualization of sense and values; the interaction of “ethos” (character and “soma” (body; the influence of the plastic images on the narrative ones; a normative typology of man; the significance of visual and acoustic perception. In this context, I studied ancient physiognomic; Aristotelian understanding of the acoustic and plastic arts; genesis, evolution and significance of the sculptural portrait image of man and the image of philosopher in Antiquity. I also pay attention to some methodological aspects of the study. As a result, there emerges an integral image of philosopher, which allows looking at the Greek culture from a fresh angle.

Art therapy for Alzheimer's disease and other dementias.

Science.gov (United States)

Chancellor, Bree; Duncan, Angel; Chatterjee, Anjan

2014-01-01

Patients with dementias commonly experience neuropsychiatric symptoms that diminish their quality of life. Pharmacologic treatments for these symptoms are limited in their efficacy. In the absence of near-future prospects for a cure for degenerative dementias, treatments that improve neuropsychiatric symptoms and quality of life are needed. We explore the hypothesis that art therapy is useful in dementia by reviewing the extant literature. With appropriate structure, patients with dementia can produce and appreciate visual art. Case studies and several small trials suggest that art therapy engages attention, provides pleasure, and improves neuropsychiatric symptoms, social behavior, and self-esteem. Whether these benefits generalize beyond the studio remains unknown. We offer a theoretical framework that motivates the use of art therapy and propose that clinical enquiry to establish methods, assess efficacy, and define optimal conditions for the use of art therapy in Alzheimer's and other dementing disorders is timely.

Quasi-static responses and variational principles in gradient plasticity

Science.gov (United States)

Nguyen, Quoc-Son

2016-12-01

Gradient models have been much discussed in the literature for the study of time-dependent or time-independent processes such as visco-plasticity, plasticity and damage. This paper is devoted to the theory of Standard Gradient Plasticity at small strain. A general and consistent mathematical description available for common time-independent behaviours is presented. Our attention is focussed on the derivation of general results such as the description of the governing equations for the global response and the derivation of related variational principles in terms of the energy and the dissipation potentials. It is shown that the quasi-static response under a loading path is a solution of an evolution variational inequality as in classical plasticity. The rate problem and the rate minimum principle are revisited. A time-discretization by the implicit scheme of the evolution equation leads to the increment problem. An increment of the response associated with a load increment is a solution of a variational inequality and satisfies also a minimum principle if the energy potential is convex. The increment minimum principle deals with stables solutions of the variational inequality. Some numerical methods are discussed in view of the numerical simulation of the quasi-static response.

Whose global art (history?: Ancient art as global art

Directory of Open Access Journals (Sweden)

Cynthia Colburn

2016-12-01

Full Text Available Discourse on global art or art history arguably dominates the field of art history today in terms of curriculum and research. This discourse cuts across time and space, impacting all art historical specializations, from prehistoric to contemporary, and from Africa to the Americas. Yet, the mainstream theoretical discourse on global art or art history focuses almost explicitly on contemporary and, to a lesser extent, modern art, operating from the premise that only these arts were created in an age of globalization and, thus, emphasize hybridity. This essay seeks to expand the mainstream theoretical discourse regarding global art to pre-modern examples, given that artistic exchange and hybridity dates as early as the prehistoric era all over the world and is not dependent on newer technologies. Indeed, one might argue that the study of pre-modern examples of global art could provide a powerful historical lens through which to analyze contemporary global art.

Transmediality in Symbolist and Surrealist Photo-Literature

Directory of Open Access Journals (Sweden)

Walden Lauren

2017-11-01

Full Text Available The fin de siècle period throughout Europe undoubtedly cultivated the “interdisciplinary principle of la fraternité des arts” (Genova 158. Literature, poetry, visual art and music superseded former hierarchical structures favouring the painterly. Correspondence between intellectuals would cross-fertilise between disparate realms through publishing in interdisciplinary cultural journals that were distributed internationally across cosmopolitan cityscapes. The ability for the photograph to be mechanically reproduced, postulated by Walter Benjamin in 1936, allowed for one of the first transmedial aesthetics, to become known as photo-literature. Previously, reproduction had been confined to the textual realm. Bruges La Morte by Georges Rodenbach was the first ever work of photo-literature to commingle these respective art forms, sixty-five years after the invention of photography in 1827. Rodenbach’s novella was first published in 1892 at the height of the symbolist movement which spanned literature, painting, photography and more. Its pseudo-progeny, Andre Breton’s surrealist text Nadja was published in 1928 depicting the author’s meandering through the Parisian cityscape. In these works, text and image engender a sense of cosmopolitanism through the function of transposition.

Further adventures of the celestial sleuth using astronomy to solve more mysteries in art, history, and literature

CERN Document Server

Olson, Donald W

2018-01-01

From the author of "Celestial Sleuth" (2014), yet more mysteries in art, history, and literature are solved by calculating phases of the Moon, determining the positions of the planets and stars, and identifying celestial objects in paintings. In addition to helping to crack difficult cases, these studies spark our imagination and provide a better understanding of the skies. Weather archives, vintage maps, tides, historical letters and diaries, military records and the assistance of experts in related fields help with this work. For each historical event influenced by astronomy, there is a different kind of mystery to be solved. How did the changing tides affect an army's battle plans? How did the phases of the moon affect how an artist painted a landscape? Follow these exciting investigations with a master “celestial sleuth” as he tracks down the truth and helps unravel mysteries as far back as the Middle Ages and as recent as the iconic 1945 photograph of a kiss in Times Square on VJ Day.

Plastic dosimeter

International Nuclear Information System (INIS)

Nagai, Shiro; Matsuda, Kohji.

1988-01-01

The report outlines major features and applications of plastic dosimeters. Some plastic dosimeters, including the CTA and PVC types, detect the response of the plastic material itself to radiations while others, such as pigment-added plastic dosimeters, contain additives as radiation detecting material. Most of these dosimeters make use of color centers produced in the dosimeter by radiations. The PMMA dosimeter is widely used in the field of radiation sterilization of food, feed and medical apparatus. The blue cellophane dosimeter is easy to handle if calibrated appropriately. The rad-color dosimeter serves to determine whether products have been irradiated appropriately. The CTA dosimeter has better damp proofing properties than the blue cellophane type. The pigment-added plastic dosimeter consists of a resin such as nylon, CTA or PVC that contains a dye. Some other plastic dosimeters are also described briefly. Though having many advantages, these plastic dosimeter have disadvantages as well. Some of their major disadvantages, including fading as well as large dependence on dose, temperature, humidity and anviroment, are discussed. (Nogami, K.)

Beyeler, Michael; Rokem, Ariel; Boynton, Geoffrey M.; Fine, Ione

The ‘bionic eye’—so long a dream of the future—is finally becoming a reality with retinal prostheses available to patients in both the US and Europe. However, clinical experience with these implants has made it apparent that the visual information provided by these devices differs substantially from normal sight. Consequently, the ability of patients to learn to make use of this abnormal retinal input plays a critical role in whether or not some functional vision is successfully regained. The goal of the present review is to summarize the vast basic science literature on developmental and adult cortical plasticity with an emphasis on how this literature might relate to the field of prosthetic vision. We begin with describing the distortion and information loss likely to be experienced by visual prosthesis users. We then define cortical plasticity and perceptual learning, and describe what is known, and what is unknown, about visual plasticity across the hierarchy of brain regions involved in visual processing, and across different stages of life. We close by discussing what is known about brain plasticity in sight restoration patients and discuss biological mechanisms that might eventually be harnessed to improve visual learning in these patients.

Growing evidence suggests that the arts may be useful in health care and in the training of health care professionals. Four art genres - novels, films, paintings and music - are examined for their potential contribution to enhancing patient health and/or making better health care providers. Based on a narrative literature review, we examine the effects of passive (e.g. reading, watching, viewing and listening) and active (e.g. writing, producing, painting and performing) exposure to the four art genres, by both patients and health care providers. Overall, an emerging body of empirical evidence indicates positive effects on psychological and physiological outcome measures in patients and some benefits to medical training. Expressive writing/emotional disclosure, psychoneuroimmunology, Theory of Mind and the Common Sense Model of Self-Regulation are considered as possible theoretical frameworks to help incorporate art genres as sources of inspiration for the further development of health psychology research and clinical applications.

2018-01-01

to evaluate the profile of patients submitted to post-bariatric plastic surgery at the North Wing Regional Hospital, Brasília, DF. we conducted a prospective, descriptive and analytical study of patients submitted to Roux-en-Y gastroplasty, and subsequently to plastic surgery, from January 2011 to December 2016. We assessed body mass index before gastroplasty and after surgery plastic surgery, postoperative complications and comorbidities. we studied 139 patients (130 women and nine men), with a mean age of 41 years, who underwent 233 operations. The mean BMI at the time of plastic surgery was 27.44kg/m2. The mean weight loss was 47.02kg and the mean maximum BMI was 45.17kg/m2. The mean time between bariatric surgery and plastic surgery was 42 months. The most important co-morbidities before plastic surgery were arterial hypertension (11.5%), arthropathy (5.4%), diabetes mellitus (5%) and metabolic syndrome (4.3%) (pprofile of post-bariatric patients who underwent plastic surgery was similar to that reported in the literature, except for the low rate of associated surgeries and postoperative complications. Plastic surgery in post-bariatric patients has led to an improvement in the quality of life in most of these patients.

Direct liquefaction of plastics and coprocessing of coal with plastics

Huffman, G.P.; Feng, Z.; Mahajan, V. [Univ. of Kentucky, Lexington, KY (United States)

1995-12-31

The objectives of this work were to optimize reaction conditions for the direct liquefaction of waste plastics and the coprocessing of coal with waste plastics. In previous work, the direct liquefaction of medium and high density polyethylene (PE), polypropylene (PPE), poly(ethylene terephthalate) (PET), and a mixed plastic waste, and the coliquefaction of these plastics with coals of three different ranks was studied. The results established that a solid acid catalyst (HZSM-5 zeolite) was highly active for the liquefaction of the plastics alone, typically giving oil yields of 80-95% and total conversions of 90-100% at temperatures of 430-450 {degrees}C. In the coliquefaction experiments, 50:50 mixtures of plastic and coal were used with a tetralin solvent (tetralin:solid = 3:2). Using approximately 1% of the HZSM-5 catalyst and a nanoscale iron catalyst, oil yields of 50-70% and total conversion of 80-90% were typical. In the current year, further investigations were conducted of the liquefaction of PE, PPE, and a commingled waste plastic obtained from the American Plastics Council (APC), and the coprocessing of PE, PPE and the APC plastic with Black Thunder subbituminous coal. Several different catalysts were used in these studies.

A fiber bundle-plastic chain model for quasi-brittle materials under uniaxial loading

International Nuclear Information System (INIS)

Shan, Zhi; Yu, Zhiwu

2015-01-01

A fiber bundle-plastic chain model for quasi-brittle materials under both uniaxial compression and tension conditions is developed. By introducing a plastic chain model into the fiber bundle model, a bundle-chain model for quasi-brittle materials is proposed with physical considerations. The model achieves a novel and convenient approach to describe the stochastic effective stress-driven plasticity. It is found that the numerical solutions obtained with this model agree with experimental results when subjected to both monotonic and cyclic uniaxial loading. The model generates a numerical solution with higher accuracy than the present models, when compared with the experimental results on certain problems. An example is shown which utilizes this model to describe the stochastic properties of a constitutive model given as standard. Furthermore, the difference between the existing plastic fiber bundle models in the literature and this model is also obtained in this work. (paper)

Do estrogenic compounds in drinking water migrating from plastic pipe distribution system pose adverse effects to human? An analysis of scientific literature.

Science.gov (United States)

Liu, Ze-Hua; Yin, Hua; Dang, Zhi

2017-01-01

With the widespread application of plastic pipes in drinking water distribution system, the effects of various leachable organic chemicals have been investigated and their occurrence in drinking water supplies is monitored. Most studies focus on the odor problems these substances may cause. This study investigates the potential endocrine disrupting effects of the migrating compound 2,4-di-tert-butylphenol (2,4-d-t-BP). The summarized results show that the migration of 2,4-d-t-BP from plastic pipes could result in chronic exposure and the migration levels varied greatly among different plastic pipe materials and manufacturing brands. Based on estrogen equivalent (EEQ), the migrating levels of the leachable compound 2,4-d-t-BP in most plastic pipes were relative low. However, the EEQ levels in drinking water migrating from four out of 15 pipes may pose significant adverse effects. With the increasingly strict requirements on regulation of drinking water quality, these results indicate that some drinking water transported with plastic pipes may not be safe for human consumption due to the occurrence of 2,4-d-t-BP. Moreover, 2,4-d-t-BP is not the only plastic pipe-migrating estrogenic compound, other compounds such as 2-tert-butylphenol (2-t-BP), 4-tert-butylphenol (4-t-BP), and others may also be leachable from plastic pipes.

Full Text Available Objective. To review the recent literature on the clinical features, genetic mutations, neurobiology associated with dysregulation of mTOR (mammalian target of rapamycin, and clinical trials for tuberous sclerosis complex (TSC, neurofibromatosis-1 (NF1 and fragile X syndrome (FXS, and phosphatase and tensin homolog hamartoma syndromes (PTHS, which are neurogenetic disorders associated with abnormalities in synaptic plasticity and mTOR signaling. Methods. Pubmed and Clinicaltrials.gov were searched using specific search strategies. Results/Conclusions. Although traditionally thought of as irreversible disorders, significant scientific progress has been made in both humans and preclinical models to understand how pathologic features of these neurogenetic disorders can be reduced or reversed. This paper revealed significant similarities among the conditions. Not only do they share features of impaired synaptic plasticity and dysregulation of mTOR, but they also share clinical features—autism, intellectual disability, cutaneous lesions, and tumors. Although scientific advances towards discovery of effective treatment in some disorders have outpaced others, progress in understanding the signaling pathways that connect the entire group indicates that the lesser known disorders will become treatable as well.

Phillips, Nicole A; Tannan, Shruti C; Kalliainen, Loree K

2016-11-01

Although explicit sex-based discrimination has largely been deemed unacceptable in professional settings, implicit gender bias persists and results in a significant lack of parity in plastic surgery and beyond. Implicit gender bias is the result of a complex interplay of cultural and societal expectations, learned behaviors, and standardized associations. As such, both male and female surgeons are subject to its influence. A review of the literature was conducted, examining theories of gender bias, current manifestations of gender bias in plastic surgery and other fields, and interventions designed to address gender bias. Multiple studies demonstrate persistent gender bias that impacts female physicians at all levels of training. Several institutions have enacted successful interventions to identify and address gender bias. Explicit gender bias has largely disappeared, yet unconscious or implicit gender bias persists. A wide-scale commitment to addressing implicit gender bias in plastic surgery is necessary and overdue. Recommendations include immediate actions that can be undertaken on an individual basis, and changes that should be implemented at a national and international level by leaders in the field.

Making the End as Good as the Beginning: Financial Planning and Retirement for Women Plastic Surgeons.

Science.gov (United States)

Johnson, Debra J; Shenaq, Deana; Thakor, Manisha

2016-10-01

Financial planning is critically important to ensure financial security both during a plastic surgical career and in retirement. Unfortunately, plastic surgery training includes very little in the way of financial planning. The information that is available in the literature is mostly geared toward men. Women, with longer lifespans and more family care responsibilities, have unique needs when it comes to financial planning. Adequate attention must also be paid to life after retirement. A plastic surgical career can be all-encompassing, and thus women need to carefully plan volunteer activities, new hobbies, and even a second career to make their retirement years fulfilling and enjoyable. Key points regarding financial planning during the various phases of a woman plastic surgeon's career are discussed. Options for retirement are presented.

2010-07-01

The oncologic management of breast cancer has evolved over the past several decades from radical mastectomy to modern-day preservation of chest and breast structures. The increased rate of mastectomies over recent years made breast reconstruction an integral part of the breast cancer management. Plastic surgery now offers patients a wide variety of reconstruction options from primary closure of the skin flaps to performance of microvascular and autologous tissue transplantation. Well-coordinated partnerships between surgical oncologists, plastic surgeons, and patients address concerns of tumor control, cosmesis, and patients' wishes. The gamut of breast reconstruction options is reviewed, particularly noting state-of-the-art techniques, as well as the advantages and disadvantages of various timing modalities.

Maladaptive spinal plasticity opposes spinal learning and recovery in spinal cord injury

Directory of Open Access Journals (Sweden)

Adam R Ferguson

2012-10-01

Full Text Available Synaptic plasticity within the spinal cord has great potential to facilitate recovery of function after spinal cord injury (SCI. Spinal plasticity can be induced in an activity-dependent manner even without input from the brain after complete SCI. The mechanistic basis for these effects is provided by research demonstrating that spinal synapses have many of the same plasticity mechanisms that are known to underlie learning and memory in the brain. In addition, the lumbar spinal cord can sustain several forms of learning and memory, including limb-position training. However, not all spinal plasticity promotes recovery of function. Central sensitization of nociceptive (pain pathways in the spinal cord may emerge with certain patterns of activity, demonstrating that plasticity within the spinal cord may contribute to maladaptive pain states. In this review we discuss interactions between adaptive and maladaptive forms of activity-dependent plasticity in the spinal cord. The literature demonstrates that activity-dependent plasticity within the spinal cord must be carefully tuned to promote adaptive spinal training. Stimulation that is delivered in a limb position-dependent manner or on a fixed interval can induce adaptive plasticity that promotes future spinal cord learning and reduces nociceptive hyper-reactivity. On the other hand, stimulation that is delivered in an unsynchronized fashion, such as randomized electrical stimulation or peripheral skin injuries, can generate maladaptive spinal plasticity that undermines future spinal cord learning, reduces recovery of locomotor function, and promotes nociceptive hyper-reactivity after spinal cord injury. We review these basic phenomena, discuss the cellular and molecular mechanisms, and discuss implications of these findings for improved rehabilitative therapies after spinal cord injury.

Full Text Available Performing an art, either by painting or by sculpturing, requires to be interdisciplinary. When an artist creates his/her work of art, the process he/she realizes is supported by different engineering disciplines. Therefore, especially modern artists need to understand engineering science and this results in transforming artists into engineers. Opportunities provided by technology and science enable artists to expand his/her vision and to improve his/her works. Especially kinetic art has become an approach that combines art with engineering. Kinetic art, which is nourished with varied disciplines, is an excellent example to prove that art is interdisciplinary and to show the relationship between artist/art and engineering.

Healthcare literature, public discourse, and policy documents continue to represent persons with dementia as "doomed" and "socially dead." This tragedy meta-narrative produces and reproduces misunderstandings about dementia and causes stigma, oppression, and discrimination for persons living with dementia. With few opportunities to challenge the dominant discourse, persons with dementia continue to be denied their citizenship rights. Drawing on the concept of narrative citizenship, we describe a community-based, critical arts-based project where persons with dementia, family members, visual and performance artists, and researchers came together to interrogate the tragedy discourse and construct an alternative narrative of dementia using the arts. Our research demonstrates the power of the arts to create transformative spaces in which to challenge dominant assumptions, foster critical reflection, and envision new possibilities for mutual support, caring, and relating. This alternative narrative supports the reclamation of citizenship for persons living with dementia and fosters the relational citizenship of all. © The Author(s) 2016.

Full Text Available Smartphones have the ability to benefit plastic surgeons in all aspects of patient care and education. With the sheer number of applications available and more being created everyday, it is easy to miss out on apps which could be of great relevance. Moreover, the range of android applications available has not been extensively discussed in the literature. To this end, we have compiled an exhaustive list of android smartphone applications, which we feel can help our day to day functioning. The apps have been extensively reviewed and neatly described along with all their potential uses. In addition, we have made an effort to highlight ′non-medical′ or efficiency apps which can improve departmental functioning. These apps have not been described in prior articles, and their functionality might not be known to all. We believe that the technology savvy plastic surgeon can make maximum use of these apps to his benefit.

Full Text Available The age old activity of collecting arts is not intrinsically dependent on the art museum as separate architectural type. How was the art museum as an independent structure conceptualized and why? What was the idea behind that concept? Was it created as a medium consciously and what kind of messages was it supposed to deliver? What kind of unique “textual” overlaps the various disciplines of archaeology, art history, politics, literature, science and architecture created in order to produce what we today recognize as art museum space? This study focuses on the crucial historical moments of the late 17th century when such questions were posed for the first time within the classical discourse of the French architectural theory which followed the consolidation of French absolutism and the foundation of the Royal academies of arts and sciences, until the mid 19th century when the answers to those questions were finally exemplified in built architecture. The study gives a comprehensive overview of the cultural context art museums as public institutions emerged from and became new spatial models for collective cultivation.

Spinal Plasticity and Behavior: BDNF-Induced Neuromodulation in Uninjured and Injured Spinal Cord

Science.gov (United States)

Huie, J. Russell

2016-01-01

Brain-derived neurotrophic factor (BDNF) is a member of the neurotrophic factor family of signaling molecules. Since its discovery over three decades ago, BDNF has been identified as an important regulator of neuronal development, synaptic transmission, and cellular and synaptic plasticity and has been shown to function in the formation and maintenance of certain forms of memory. Neural plasticity that underlies learning and memory in the hippocampus shares distinct characteristics with spinal cord nociceptive plasticity. Research examining the role BDNF plays in spinal nociception and pain overwhelmingly suggests that BDNF promotes pronociceptive effects. BDNF induces synaptic facilitation and engages central sensitization-like mechanisms. Also, peripheral injury-induced neuropathic pain is often accompanied with increased spinal expression of BDNF. Research has extended to examine how spinal cord injury (SCI) influences BDNF plasticity and the effects BDNF has on sensory and motor functions after SCI. Functional recovery and adaptive plasticity after SCI are typically associated with upregulation of BDNF. Although neuropathic pain is a common consequence of SCI, the relation between BDNF and pain after SCI remains elusive. This article reviews recent literature and discusses the diverse actions of BDNF. We also highlight similarities and differences in BDNF-induced nociceptive plasticity in naïve and SCI conditions.

It is concluded that the proposed Visual Arts curriculum is a powerful educational tool to assist teachers to contextualize arts teaching; help students to express their ideas and emotions based on a critical, reflective, and permanent attitude; and generate opportunities for personal growth focused on the acquisition of creative skills and models of arts education which contribute, as a whole, to the development of human capacities.

Plastic condoms.

Science.gov (United States)

1968-01-01

Only simple equipment, simple technology and low initial capital investment are needed in their manufacture. The condoms can be made by people who were previously unskilled or only semi-skilled workers. Plastic condoms differ from those made of latex rubber in that the nature of the plastic film allows unlimited shelf-life. Also, the plastic has a higher degree of lubricity than latex rubber; if there is a demand for extra lubrication in a particular market, this can be provided. Because the plastic is inert, these condoms need not be packaged in hermetically sealed containers. All these attributes make it possible to put these condoms on the distributors' shelves in developing countries competitively with rubber condoms. The shape of the plastic condom is based on that of the lamb caecum, which has long been used as luxury-type condom. The plastic condom is made from plastic film (ethylene ethyl acrilate) of 0.001 inch (0.0254 mm.) thickness. In addition, a rubber ring is provided and sealed into the base of the condom for retention during coitus. The advantage of the plastic condom design and the equipment on which it is made is that production can be carried out either in labour-intensive economy or with varying degrees of mechanization and automation. The uniform, finished condom if made using previously untrained workers. Training of workers can be done in a matter of hours on the two machines which are needed to produce and test the condoms. The plastic film is provided on a double wound roll, and condom blanks are prepared by means of a heat-sealing die on the stamping machine. The rubber rings are united to the condom blanks on an assembly machine, which consists of a mandrel and heat-sealing equipment to seal the rubber ring to the base of the condom. Built into the assembly machine is a simple air-testing apparatus that can detect the smallest pinhole flaw in a condom. The manufacturing process is completed by unravelling the condom from the assembly

Art-inspired Presentation of Earth Science Research

2016-12-01

This presentation features two posters inspired by modern and contemporary art that showcase different Earth science data at NASA's Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC). The posters are intended for the science-interested public. They are designed to tell an interesting story and to stimulate interest in the science behind the art. "Water makes the World" is a photo mosaic of cloud water droplet and ice crystal images combined to depict the Earth in space. The individual images were captured using microphysical probes installed on research aircraft flown in the Mid-latitude Continental Convective Clouds Experiment (MC3E). MC3E was one of a series of ground validation field experiments for NASA's Global Precipitation Measurement (GPM) mission which collected ground and airborne precipitation datasets supporting the physical validation of satellite-based precipitation retrieval algorithms. "The Lightning Capital of the World" is laid out on a grid of black lines and primary colors in the style of Piet Mondrian. This neoplastic or "new plastic art" style was founded in the Netherlands and was used in art from 1917 to 1931. The poster colorfully describes the Catatumbo lightning phenomenon from a scientific, social and historical perspective. It is a still representation of a moving art project. To see this poster in action, visit the GHRC YouTube channel at http://tinyurl.com/hd6crx8 or stop by during the poster session. Both posters were created for a special Research as Art session at the 2016 Federation of Earth Science Information Partners (ESIP) summer meeting in Durham, NC. This gallery-style event challenged attendees to use visual media to show how the ESIP community uses data. Both of these visually appealing posters draw the viewer in and then provide information on the science data used, as well as links for more information available. The GHRC DAAC is a joint venture of NASA's Marshall Space Flight Center and the

Biodegradability of plastics.

2009-08-26

Plastic is a broad name given to different polymers with high molecular weight, which can be degraded by various processes. However, considering their abundance in the environment and their specificity in attacking plastics, biodegradation of plastics by microorganisms and enzymes seems to be the most effective process. When plastics are used as substrates for microorganisms, evaluation of their biodegradability should not only be based on their chemical structure, but also on their physical properties (melting point, glass transition temperature, crystallinity, storage modulus etc.). In this review, microbial and enzymatic biodegradation of plastics and some factors that affect their biodegradability are discussed.

Marketing and materiality in the popular music transmedia of Gorillaz’ Plastic Beach

Directory of Open Access Journals (Sweden)

Alex JEFFERY

2017-07-01

Full Text Available The entertainment complexes of narrative transmedia contain few instances based in popular music. However, those that exist provide intriguing case studies, highly distinct from those based in film and television. The most fully realized of these, Gorillaz’ Plastic Beach (2010, is rich in visual media typical of popular music culture, including sleeve art, animated music videos. The tangible materiality foregrounded in these visuals stems from the main ecological theme of the album: the disposability of plastic waste. Using methods of analysis of the original texts, and a survey of the networked fan practices that respond to them, the essay theorizes that the material and haptic invitation in these visuals is at odds with the diminishing presence of physical consumables within popular music culture. It then argues that fans enter into this gap with their own creative practices, making and playing with hand-made or customized objects inspired by Plastic Beach, activating unexploited, marketing potential within the album. Although current applications of this research are limited due to the low frequency of popular music transmedia case studies, it points the way forward to theoretically more successful marketing strategies in the future.

This paper studies the recyclability of construction and household plastic waste collected from local landfills. Samples were processed from mixed plastic waste by injection moulding. In addition, blends of pure plastics, polypropylene and polyethylene were processed as a reference set. Reference samples with known plastic ratio were used as the calibration set for quantitative analysis of plastic fractions in recycled blends. The samples were tested for the tensile properties; scanning electron microscope-energy-dispersive X-ray spectroscopy was used for elemental analysis of the blend surfaces and Fourier transform infrared (FTIR) analysis was used for the quantification of plastics contents.

2018-04-01

This is the first study to report on the prevalence of cosmetic facial plastic surgery use among facial plastic surgeons. The aim of this study is to determine the frequency with which facial plastic surgeons have cosmetic procedures themselves. A secondary aim is to determine whether trends in usage of cosmetic facial procedures among facial plastic surgeons are similar to that of nonsurgeons. The study design was an anonymous, five-question, Internet survey distributed via email set in a single academic institution. Board-certified members of the American Academy of Facial Plastic and Reconstructive Surgery (AAFPRS) were included in this study. Self-reported history of cosmetic facial plastic surgery or minimally invasive procedures were recorded. The survey also queried participants for demographic data. A total of 216 members of the AAFPRS responded to the questionnaire. Ninety percent of respondents were male ( n  = 192) and 10.3% were female ( n  = 22). Thirty-three percent of respondents were aged 31 to 40 years ( n  = 70), 25% were aged 41 to 50 years ( n  = 53), 21.4% were aged 51 to 60 years ( n  = 46), and 20.5% were older than 60 years ( n  = 44). Thirty-six percent of respondents had a surgical cosmetic facial procedure and 75% has at least one minimally invasive cosmetic facial procedure. Facial plastic surgeons are frequent users of cosmetic facial plastic surgery. This finding may be due to access, knowledge base, values, or attitudes. By better understanding surgeon attitudes toward facial plastic surgery, we can improve communication with patients and delivery of care. This study is a first step in understanding use of facial plastic procedures among facial plastic surgeons. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

O convite é para percorrer trajetos em encontros com a arte, com a palavra “estética”, com a potencialidade da arte contemporânea, com o “olhar de missão francesa” que teima em considerar a arte como expressão da beleza. No percurso, a proposição da leitura de uma imagem incompleta, tenta provocar idas e voltas conceituais na percepção do próprio ato de leitura oferecida como curadoria educativa na processualidade da mediação cultural. Declanchar, tirar a tranca. Não será esta a tarefa maior da mediação cultural: abrir o que estava travado, libertar o olhar amarrado ao já conhecido para ver além? Não será este o sentido da educação estética? Os territórios de arte de arte & cultura, instigando o pensamento rizomático, não seriam nutrição estética para ir além das obras de arte conhecidas e das biografias dos artistas? Na ampliação de horizontes, cabe ao leitor a resposta: Afinal, arte, só na aula de arte?

Full Text Available Every society is composed of individuals who share a common culture thorough the language they use. The continuity of this culture and its transmission to the other generations are mostly made through the language. The literary works are those transponders that convey the cultural heritage of the nations to the future and put a light on the past. Although literature is supposed to do so, the language is shaped in the hands of master of languages; namely, literary men. As famous Russian literary critic, writer and philosopher Belinski said, literature is the best expression of a nation’s spirit in the medium of language. In another word, the literature is to add something from the soul, feelings into the work of art by using language.

Recycling of plastic waste: Presence of phthalates in plastics from households and industry.

Plastics recycling has the potential to substitute virgin plastics partially as a source of raw materials in plastic product manufacturing. Plastic as a material may contain a variety of chemicals, some potentially hazardous. Phthalates, for instance, are a group of chemicals produced in large volumes and are commonly used as plasticisers in plastics manufacturing. Potential impacts on human health require restricted use in selected applications and a need for the closer monitoring of potential sources of human exposure. Although the presence of phthalates in a variety of plastics has been recognised, the influence of plastic recycling on phthalate content has been hypothesised but not well documented. In the present work we analysed selected phthalates (DMP, DEP, DPP, DiBP, DBP, BBzP, DEHP, DCHP and DnOP) in samples of waste plastics as well as recycled and virgin plastics. DBP, DiBP and DEHP had the highest frequency of detection in the samples analysed, with 360μg/g, 460μg/g and 2700μg/g as the maximum measured concentrations, respectively. Among other, statistical analysis of the analytical results suggested that phthalates were potentially added in the later stages of plastic product manufacturing (labelling, gluing, etc.) and were not removed following recycling of household waste plastics. Furthermore, DEHP was identified as a potential indicator for phthalate contamination of plastics. Close monitoring of plastics intended for phthalates-sensitive applications is recommended if recycled plastics are to be used as raw material in production. Copyright © 2016 Elsevier Ltd.

In this paper the elastic-plastic behaviour of thick-walled pressure vessels with internal and external pressure is studied. To describe the mechanical behaviour of isotropic, plastic compressible materials we use a plastic potential which is a single-valued function of the principle stresses. For cylinders and spheres an analytic expression for the computation of stresses and residual stresses is specified. Afterwards the strains are calculated by using the finite difference method. Some examples will high-light the influence of the plastic compressibility on the behaviour of pressure vessels. (orig.) [de

Smoking increases perioperative risk regarding wound healing, infection rate and failure of microsurgical procedures. There is no present consensus about plastic and aesthetic surgical indications concerning smoking patients. The aim of our study is to analyze French plastic surgeons practices concerning smokers. A questionnaire was send by e-mail to French plastic surgeons in order to evaluate their own operative indications: patient information about smoking dangers, pre- and postoperative delay of smoking cessation, type of intervention carried out, smoking cessation supports, use of screening test and smoking limit associated to surgery refusing were studied. Statistical tests were used to compare results according to practitioner activity (liberal or public), own smoking habits and time of installation. In 148 questionnaires, only one surgeon did not explain smoking risk. Of the surgeons, 49.3% proposed smoking-cessation supports, more frequently with public practice (P=0.019). In total, 85.4% of surgeons did not use screening tests. Years of installation affected operative indication with smoking patients (P=0.02). Pre- and postoperative smoking cessation delay were on average respectively 4 and 3 weeks in accordance with literature. Potential improvements could be proposed to smoking patients' care: smoking cessation assistance, screening tests, absolute contraindication of some procedures or level of consumption to determine.

Mechanically equivalent elastic-plastic deformations and the problem of plastic spin

Directory of Open Access Journals (Sweden)

Steigmann David J.

2011-01-01

Full Text Available The problem of plastic spin is phrased in terms of a notion of mechanical equivalence among local intermediate configurations of an elastic/ plastic crystalline solid. This idea is used to show that, without further qualification, the plastic spin may be suppressed at the constitutive level. However, the spin is closely tied to an underlying undistorted crystal lattice which, once specified, eliminates the freedom afforded by mechanical equivalence. As a practical matter a constitutive specification of plastic spin is therefore required. Suppression of plastic spin thus emerges as merely one such specification among many. Restrictions on these are derived in the case of rate-independent response.

The developmental potential of art activities at the preschool age

Directory of Open Access Journals (Sweden)

Večanski Vera D.

2017-01-01

Full Text Available In traditional approaches to the teaching of art and arts activities at the preschool age, art has been viewed mostly in terms of emotional self-expression and development. According to this view, art and arts activities foster the development of creativity, imagination and emotions, but little consideration is given to their link to cognitive processes and to their synthetic character. In general education, art and arts activities are often relegated to marginal status. This paper presents a theoretical examination of the potential of arts activities to enhance the development of a well-rounded personality in children. Through a theoretical analysis of the relevant literature, research and ideas in recent theory which emphasize the synthetic character of art, the potential of arts activities in all segments of development and creativity at the preschool age has been examined. However, in obtaining the full benefit of arts activities in practice, the manner in which arts activities with children at this age are carried out is extremely important. Of particular importance in this process is the influence and role of early childhood educators, who should act as mediators, partners and co-explorers, facilitating, supporting, enriching and participating in the process of free exploration and creativity. Giving primacy to these roles of a teacher would help bring about a change in the child's position in early childhood education and would also change and expand the child's range of activities.

Virtual Reality and Serious Games in Neurorehabilitation of Children and Adults: Prevention, Plasticity, and Participation.

Deutsch, Judith E; Westcott McCoy, Sarah

2017-07-01

Use of virtual reality (VR) and serious games (SGs) interventions within rehabilitation as motivating tools for task specific training for individuals with neurological conditions are fast-developing. Within this perspective paper we use the framework of the IV STEP conference to summarize the literature on VR and SG for children and adults by three topics: Prevention; Outcomes: Body-Function-Structure, Activity and Participation; and Plasticity. Overall the literature in this area offers support for use of VR and SGs to improve body functions and to some extent activity domain outcomes. Critical analysis of clients' goals and selective evaluation of VR and SGs are necessary to appropriately take advantage of these tools within intervention. Further research on prevention, participation, and plasticity is warranted. We offer suggestions for bridging the gap between research and practice integrating VR and SGs into physical therapist education and practice.

Quantifying the development of user-generated art during 2001-2010.

Yazdani, Mehrdad; Chow, Jay; Manovich, Lev

2017-01-01

One of the main questions in the humanities is how cultures and artistic expressions change over time. While a number of researchers have used quantitative computational methods to study historical changes in literature, music, and cinema, our paper offers the first quantitative analysis of historical changes in visual art created by users of a social online network. We propose a number of computational methods for the analysis of temporal development of art images. We then apply these methods to a sample of 270,000 artworks created between 2001 and 2010 by users of the largest social network for art-DeviantArt (www.deviantart.com). We investigate changes in subjects, techniques, sizes, proportions and also selected visual characteristics of images. Because these artworks are classified by their creators into two general categories-Traditional Art and Digital Art-we are also able to investigate if the use of digital tools has had a significant effect on the content and form of artworks. Our analysis reveals a number of gradual and systematic changes over a ten-year period in artworks belonging to both categories.

Surgical site infection rates are of great interest to patients, surgeons, hospitals and third-party payers. While previous studies have reported hospital-acquired infection rates that are nonspecific to all surgical services, there remain no overall reported infection rates focusing specifically on plastic surgery in the literature. To estimate the reported surgical site infection rate in plastic surgery procedures over a 10-year period at an academic hospital in Canada. A review was conducted on reported plastic surgery surgical site infection rates from 2003 to 2013, based on procedures performed in the main operating room. For comparison, prospective infection surveillance data over an eight-year period (2005 to 2013) for nonplastic surgery procedures were reviewed to estimate the overall operative surgical site infection rates. A total of 12,183 plastic surgery operations were performed from 2003 to 2013, with 96 surgical site infections reported, corresponding to a net operative infection rate of 0.79%. There was a 0.49% surgeon-reported infection rate for implant-based procedures. For non-plastic surgery procedures, surgical site infection rates ranged from 0.04% for cataract surgery to 13.36% for high-risk abdominal hysterectomies. The plastic surgery infection rate at the study institution was found to be site infection rates. However, these results do not report patterns of infection rates germane to procedures, season, age groups or sex. To provide more in-depth knowledge of this topic, multicentre studies should be conducted.

There have always been debates about possible correlations between creative genius and mental illness, not only among psychiatrists but also among scientists of art and literature. Especially modern literary texts may show formal similarities to psychotic speech, which leads to the question, whether not only artists, but also people in psychotic states are able to create literature. This article points out the loosened semantic stability in psychotic speech, which equals a loss of common ground in the use of signs and symbols. In terms of Gadamer's hermeneutics, texts produced by psychotic people cannot be understood, they are mere form. Even in hermetic literary texts, the semantic code can be offended, but in deliberate artistic intention, which finds its communicative purpose in breaking the symbolic order.

The aim of this paper was to collect currently available data related to the use of stem cells in aesthetic dermatology and plastic surgery based on a systemic review of experimental and clinical applications. We found that the use of stem cells is very promising but the current state of art is still not effective. This situation is connected with not fully known mechanisms of cell interactions, possible risks and side effects. We think that there is a big need to create and conduct different studies which could resolve problems of stem cells use for implementation into aesthetic dermatology and plastic surgery.

2010-12-01

Professional nursing defines its foundation of practice as embedded in the sciences and humanities of a liberal education. This liberal education is commonly alluded to with the phrase "the art and science of nursing." Yet how do we as nursing educators integrate these two concepts? This article describes a method of integrating the humanities as part of an innovative clinical experience. A defined visual art experience was used to improve professional nursing students' observational and communication skills, narrative sequencing abilities, and empathy. The nursing and medical literature describing the use of visual art encounters in health care education is reviewed. The incorporation of an art education program into the curriculum of a cohort of accelerated baccalaureate nursing students is described. Qualitative evaluation measures from the students suggest this was an experience that broadened their understanding of patient encounters. Copyright 2010, SLACK Incorporated.

Recycling of waste plastics still remains a challenging area in the waste management sector. The current and potential goals proposed on EU or regional levels are difficult to achieve, and even to partially fullfil them the improvements in collection and sorting should be considerable. A study...... was undertaken to investigate the factors affecting quality in plastics recycling. The preliminary results showed factors primarily influencing quality of plastics recycling to be polymer cross contamination, presence of additives, non-polymer impurities, and polymer degradation. Deprivation of plastics quality......, with respect to recycling, has been shown to happen throughout the plastics value chain, but steps where improvements may happen have been preliminary identified. Example of Cr in plastic samples analysed showed potential spreading and accumulation of chemicals ending up in the waste plastics. In order...

Individual differences in behavioural plasticities.

Stamps, Judy A

2016-05-01

Interest in individual differences in animal behavioural plasticities has surged in recent years, but research in this area has been hampered by semantic confusion as different investigators use the same terms (e.g. plasticity, flexibility, responsiveness) to refer to different phenomena. The first goal of this review is to suggest a framework for categorizing the many different types of behavioural plasticities, describe examples of each, and indicate why using reversibility as a criterion for categorizing behavioural plasticities is problematic. This framework is then used to address a number of timely questions about individual differences in behavioural plasticities. One set of questions concerns the experimental designs that can be used to study individual differences in various types of behavioural plasticities. Although within-individual designs are the default option for empirical studies of many types of behavioural plasticities, in some situations (e.g. when experience at an early age affects the behaviour expressed at subsequent ages), 'replicate individual' designs can provide useful insights into individual differences in behavioural plasticities. To date, researchers using within-individual and replicate individual designs have documented individual differences in all of the major categories of behavioural plasticities described herein. Another important question is whether and how different types of behavioural plasticities are related to one another. Currently there is empirical evidence that many behavioural plasticities [e.g. contextual plasticity, learning rates, IIV (intra-individual variability), endogenous plasticities, ontogenetic plasticities) can themselves vary as a function of experiences earlier in life, that is, many types of behavioural plasticity are themselves developmentally plastic. These findings support the assumption that differences among individuals in prior experiences may contribute to individual differences in behavioural

To retrospectively evaluate the effectiveness of Botulinum Toxin Type A (BTX-A) injections relieve pain in the field of plastic surgery and postoperative rehabilitation, and discuss the analgesic mechanism of BTX- A in plastics and related research progress. From appearance to September 1, 2016, PUBMED, EMBASE, and Web of Science were searched, using the key words related to "Botulinum Toxin Type A" and "Pain." Furtherly, nonplastic surgery-related literature was excluded by manual screening. Eleven literatures met the inclusion criteria, including 6 prospective controlled cohorts, 4 patient series, and 1 retrospective cohort. These studies involved Lower Limb, Breast, Hallux, Amputees, and Temporomandibular joint disk disfigurement and enrolled 402 patients. Among the patients, 360 received intraoperative BTX-A injection at the time of the main surgical procedure, 16 injected postoperatively and 26 did not undergo surgery. And 85.32% reported pain alleviation and 69.96% got favorable side effects and no one occurred major adverse effects. But 1.83% accepted injections more than once. Mechanism analysis explained these studies' results and demonstrated the analgesic effectiveness of BTX-A in plastics with nociceptive pain, inflammatory pain, and neuropathic pain. The results suggest that BTX-A may induce postoperative pain associated with plastic surgeries relief. But the available data of outcome assessment involved in this review are inconsistent and failed to meet methodological rigor. And pain alleviations are influenced by many factors. So further randomized controlled clinical trials with large sample sizes are needed to support this practice, determine standard usage methods, and establish corresponding specification systems.

Stress corrosion cracking (SCC) is enhanced by cold work and causes many problems in components of the nuclear power plants. Besides, during manufacturing, installation, welding and service of the material, residual strains can be produced increasing the susceptibility to SCC. For this reason, it is important to characterize the degree of plastic strain due to dislocation accumulation in each crystal. Electron backscatter diffraction (EBSD), in conjunction with scanning electron microscope (SEM), has been a great advance in this field because it enables to estimate the plastic strain in a quick and easy way. Nevertheless, over the last few years, a lot of different mathematical expressions to estimate the plastic strain have appeared in the literature. This situation hinders the election of one of them by a novel scientist in this field. Therefore, in this paper some of the more common expressions used in the calculation of the angular misorientation have been presented and discussed in order to clarify their more important aspects. Then, using one of these expressions (average local misorientation), curves relating misorientation density with known levels of strain will be obtained for an austenitic stainless steel 304L and nickel base alloy 690, which have shown a linear behaviour that is in good agreement with results found in the literature. Finally, using curves obtained in previous steps, levels of plastic strain in a plate of nickel base alloy 600 welded with weld metal 182 were estimated between 8 and 10% for a high temperature mill annealing sample.

Durability of wood plastic composites manufactured from recycled plastic

Directory of Open Access Journals (Sweden)

Irina Turku

2018-03-01

Full Text Available The influence of accelerated weathering, xenon-arc light and freeze-thaw cycling on wood plastic composites extruded from a recycled plastic was studied. The results showed that, in general, weathering had a stronger impact on samples made from plastic waste compared to a sample made from virgin material. After weathering, the mechanical properties, tensile and flexural, were reduced by 2–30%, depending on the plastic source. Wettability of the samples was shown to play a significant role in their stability. Chemical analysis with infrared spectroscopy and surface observation with a scan electron microscope confirmed the mechanical test results. Incorporation of carbon black retained the properties during weathering, reducing the wettability of the sample, diminishing the change of mechanical properties, and improving color stability.

2008-01-01

Why are some traits constitutive and others inducible? The term costs often appears in work addressing this issue but may be ambiguously defined. This review distinguishes two conceptually distinct types of costs: phenotypic costs and plasticity costs. Phenotypic costs are assessed from patterns...... of covariation, typically between a focal trait and a separate trait relevant to fitness. Plasticity costs, separable from phenotypic costs, are gauged by comparing the fitness of genotypes with equivalent phenotypes within two environments but differing in plasticity and fitness. Subtleties associated with both...... types of costs are illustrated by a body of work addressing predator-induced plasticity. Such subtleties, and potential interplay between the two types of costs, have also been addressed, often in studies involving genetic model organisms. In some instances, investigators have pinpointed the mechanistic...

A natural plasticizer cardanol derivatives glycidyl ether (CGE) was synthesized and employed as a plasticizer for the poly(vinyl chloride). The effect of CGE on thermal degradation of PVC films and its plasticizing mechanism were firstly reported. The molecular structure of CGE was characterized with Fourier transform infrared spectroscopy (FTIR). Thermal properties, degradation properties and compatibility of the PVC films were investigated by Differential scanning calorimeter analysis (DSC), Thermogravimetric analysis (TGA) and FTIR, respectively. Compared with the commercial plasticizers dioctylphthalate (DOP), CGE can endow PVC film with a decrease of 4.31 °C in glass transition temperature (Tg), an increase of 24.01 °C and 25.53 °C in 10% weight loss (T 10) and 50% weight loss (T 50) respectively, and a higher activetion energy of thermal degradation (Ea ).

Description of creep-plasticity interaction with non-unified constitutive equations: Application to an austenitic stainless steel

International Nuclear Information System (INIS)

Contesti, E.; Cailletaud, G.

1989-01-01

We present constitutive equations able to account for time independent plasticity together with creep and creep-plasticity interaction. A classical decomposition of the inelastic strain into a time independent plastic strain and a time dependent viscoplastic part is assumed. The coupling between both deformation modes (i.e. creep and plasticity) is obtained through an interaction between the plastic and viscoplastic state variables. In a first part, the capabilities of the model are described, and qualitative identifications are given in order to characterize the behaviour of the model. The practical applicability of the model is then tested, mainly using test results from the literature, but also specific data including creep, relaxation and tensile tests with various loading rates, as reported in the paper. The model is found able to discriminate between the increase of hardening produced by plasticity or creep. The effect of the loading rate on the subsequent amount of relaxation is correctly described and a good general agreement is observed between experiment and model predictions, even for complex loading paths (monotonic with temporary unloading periods, multiaxial loading paths in the stress space).

Neural Plasticity and Proliferation in the Generation of Antidepressant Effects: Hippocampal Implication

Directory of Open Access Journals (Sweden)

Fuencisla Pilar-Cuéllar

2013-01-01

Full Text Available It is widely accepted that changes underlying depression and antidepressant-like effects involve not only alterations in the levels of neurotransmitters as monoamines and their receptors in the brain, but also structural and functional changes far beyond. During the last two decades, emerging theories are providing new explanations about the neurobiology of depression and the mechanism of action of antidepressant strategies based on cellular changes at the CNS level. The neurotrophic/plasticity hypothesis of depression, proposed more than a decade ago, is now supported by multiple basic and clinical studies focused on the role of intracellular-signalling cascades that govern neural proliferation and plasticity. Herein, we review the state-of-the-art of the changes in these signalling pathways which appear to underlie both depressive disorders and antidepressant actions. We will especially focus on the hippocampal cellularity and plasticity modulation by serotonin, trophic factors as brain-derived neurotrophic factor (BDNF, and vascular endothelial growth factor (VEGF through intracellular signalling pathways—cAMP, Wnt/β-catenin, and mTOR. Connecting the classic monoaminergic hypothesis with proliferation/neuroplasticity-related evidence is an appealing and comprehensive attempt for improving our knowledge about the neurobiological events leading to depression and associated to antidepressant therapies.

Species are the unit of analysis in many global change and conservation biology studies; however, species are not uniform entities but are composed of different, sometimes locally adapted, populations differing in plasticity. We examined how intraspecific variation in thermal niches and phenotypic plasticity will affect species distributions in a warming climate. We first developed a conceptual model linking plasticity and niche breadth, providing five alternative intraspecific scenarios that are consistent with existing literature. Secondly, we used ecological niche-modeling techniques to quantify the impact of each intraspecific scenario on the distribution of a virtual species across a geographically realistic setting. Finally, we performed an analogous modeling exercise using real data on the climatic niches of different tree provenances. We show that when population differentiation is accounted for and dispersal is restricted, forecasts of species range shifts under climate change are even more pessimistic than those using the conventional assumption of homogeneously high plasticity across a species' range. Suitable population-level data are not available for most species so identifying general patterns of population differentiation could fill this gap. However, the literature review revealed contrasting patterns among species, urging greater levels of integration among empirical, modeling and theoretical research on intraspecific phenotypic variation. © 2014 The Authors.

In this report, we present a multi-scale computational model to simulate plastic deformation of tantalum and validating experiments. In atomistic/ dislocation level, dislocation kink- pair theory is used to formulate temperature and strain rate dependent constitutive equations. The kink-pair theory is calibrated to available data from single crystal experiments to produce accurate and convenient constitutive laws. The model is then implemented into a BCC crystal plasticity finite element method (CP-FEM) model to predict temperature and strain rate dependent yield stresses of single and polycrystalline tantalum and compared with existing experimental data from the literature. Furthermore, classical continuum constitutive models describing temperature and strain rate dependent flow behaviors are fit to the yield stresses obtained from the CP-FEM polycrystal predictions. The model is then used to conduct hydro- dynamic simulations of Taylor cylinder impact test and compared with experiments. In order to validate the proposed tantalum CP-FEM model with experiments, we introduce a method for quantitative comparison of CP-FEM models with various experimental techniques. To mitigate the effects of unknown subsurface microstructure, tantalum tensile specimens with a pseudo-two-dimensional grain structure and grain sizes on the order of millimeters are used. A technique combining an electron back scatter diffraction (EBSD) and high resolution digital image correlation (HR-DIC) is used to measure the texture and sub-grain strain fields upon uniaxial tensile loading at various applied strains. Deformed specimens are also analyzed with optical profilometry measurements to obtain out-of- plane strain fields. These high resolution measurements are directly compared with large-scale CP-FEM predictions. This computational method directly links fundamental dislocation physics to plastic deformations in the grain-scale and to the engineering-scale applications. Furthermore, direct

The computational power of astrocyte mediated synaptic plasticity

Directory of Open Access Journals (Sweden)

Rogier eMin

2012-11-01

Full Text Available Research in the last two decades has made clear that astrocytes play a crucial role in the brain beyond their functions in energy metabolism and homeostasis. Many studies have shown that astrocytes can dynamically modulate neuronal excitability and synaptic plasticity, and might participate in higher brain functions like learning and memory. With the plethora of astrocyte-mediated signaling processes described in the literature today, the current challenge is to identify which of these processes happen under what physiological condition, and how this shapes information processing and, ultimately, behavior. To answer these questions will require a combination of advanced physiological, genetical and behavioral experiments. Additionally, mathematical modeling will prove crucial for testing predictions on the possible functions of astrocytes in neuronal networks, and to generate novel ideas as to how astrocytes can contribute to the complexity of the brain. Here, we aim to provide an outline of how astrocytes can interact with neurons. We do this by reviewing recent experimental literature on astrocyte-neuron interactions, discussing the dynamic effects of astrocytes on neuronal excitability and short- and long-term synaptic plasticity. Finally, we will outline the potential computational functions that astrocyte-neuron interactions can serve in the brain. We will discuss how astrocytes could govern metaplasticity in the brain, how they might organize the clustering of synaptic inputs, and how they could function as memory elements for neuronal activity. We conclude that astrocytes can enhance the computational power of neuronal networks in previously unexpected ways.

Reduction mammoplasty is an often-performed procedure by plastic surgeons and increasingly by general surgeons. The question has been posed in both general surgical literature and plastic surgical literature as to whether this procedure should remain the domain of surgical specialists. Some general surgeons are trained in breast reductions, whereas all plastic surgeons receive training in this procedure. The National Surgical Quality Improvement Project provides a unique opportunity to compare the 2 surgical specialties in an unbiased manner in terms of preoperative comorbidities and 30-day postoperative complications. The National Surgical Quality Improvement Project database was queried for the years 2005-2012. Patients were identified as having undergone a reduction mammoplasty by Current Procedural Terminology codes. RESULTS were refined to include only females with an International Classification of Diseases, Ninth Revision, code of 611.1 (hypertrophy of breasts). Information was collected regarding age, surgical specialty performing procedure, body mass index, and other preoperative variables. The outcomes utilized were presence of superficial surgical site infection, presence of deep surgical site infection, presence of wound dehiscence, postoperative respiratory compromise, pulmonary embolism, deep vein thrombosis, perioperative transfusion, operative time, reintubation, reoperation, and length of hospital stay. During this time period, there were 6239 reduction mammaplasties performed within the National Surgical Quality Improvement Project database: 339 by general surgery and 5900 by plastic surgery. No statistical differences were detected between the 2 groups with regard to superficial wound infections, deep wound infections, organ space infections, or wound dehiscence. There were no significant differences noted between within groups with regard to systemic postoperative complications. Patients undergoing a procedure by general surgery were more likely

Plutonium solution storage in plastic bottles: Operational experience and safety issues

International Nuclear Information System (INIS)

Conner, W.V.

1995-01-01

Computer spread sheet models were developed to gain a better understanding of the factors that lead to pressurization and failure of plastic bottles containing plutonium solutions. These models were developed using data obtained from the literature on gas generation rates for plutonium solutions. Leak rates from sealed plastic bottles were obtained from bottle leak tests conducted at Rocky Flats. Results from these bottle leak tests showed that narrow mouth four liter bottles will seal much better than wide mouth four liter bottles. The gas generation rate and leak rate data were used to develop models for predicting the rate of pressurization and maximum pressures expected in sealed bottles of plutonium solution containing various plutonium and acid concentrations. The computer models were used to develop proposed time limits for storing or transporting plutonium solutions in sealed plastic bottles. For plutonium solutions containing 1.5 g/l plutonium, storage in sealed bottles should not be allowed. However, transportation of higher concentration plutonium solution in sealed bottles is required, and safe transportation times of 1 shift to 6 days are proposed

Time between plastic displacements of elasto-plastic oscillators subject to Gaussian white noise

DEFF Research Database (Denmark)

Tarp-Johansen, Niels Jacob; Ditlevsen, Ove Dalager

2001-01-01

A one degree of freedom elasto-plastic oscillator subject to stationary Gaussian white noise has a plastic displacement response process of intermittent character. During shorter or longer time intervals the oscillator vibrates within the elastic domain without undergoing any plastic displacements...... between the clumps of plastic displacements. This is needed for a complete description of the plastic displacement process. A quite accurate fast simulation procedure is presented based on an amplitude model to determine the short waiting times in the transient regime of the elastic vibrations existing...

Redies, Christoph; Brachmann, Anselm

2017-01-01

Several statistical image properties have been associated with large subsets of traditional visual artworks. Here, we investigate some of these properties in three categories of art that differ in artistic claim and prestige: (1) Traditional art of different cultural origin from established museums and art collections (oil paintings and graphic art of Western provenance, Islamic book illustration and Chinese paintings), (2) Bad Art from two museums that collect contemporary artworks of lesser importance (© Museum Of Bad Art [MOBA], Somerville, and Official Bad Art Museum of Art [OBAMA], Seattle), and (3) twentieth century abstract art of Western provenance from two prestigious museums (Tate Gallery and Kunstsammlung Nordrhein-Westfalen). We measured the following four statistical image properties: the fractal dimension (a measure relating to subjective complexity); self-similarity (a measure of how much the sections of an image resemble the image as a whole), 1st-order entropy of edge orientations (a measure of how uniformly different orientations are represented in an image); and 2nd-order entropy of edge orientations (a measure of how independent edge orientations are across an image). As shown previously, traditional artworks of different styles share similar values for these measures. The values for Bad Art and twentieth century abstract art show a considerable overlap with those of traditional art, but we also identified numerous examples of Bad Art and abstract art that deviate from traditional art. By measuring statistical image properties, we quantify such differences in image composition for the first time.

[Application of biodegradable plastic film to reduce plastic film residual pollution in Chinese agriculture].

Yan, Changrong; He, Wenqing; Xue, Yinghao; Liu, Enke; Liu, Qin

2016-06-25

Plastic film has become an important agriculture production material in recent years. Over the past three decades, the amount and application area of plastic film have increased steadily, and in 2014, which are 1.4 million tons and more than 180 million hm² respectively. It plays a key role for ensuring the supply of agricultural goods in China. Meanwhile, plastic film residual pollution becomes more and more serious, and in some regions, the amount of plastic film residues has reached over 250 kg/hm². In part of the Northwest region, soil structure of farmland has been destroyed by plastic film residues and then crop growth and farming operations were suppressed. It is recognized as a good choice to replace plastic film with biodegradable plastic film, an effective measure to solve the plastic film residue pollution. Now, it is in a critical stage of study and assessment of biodegradable plastic film in China and fortunately some biodegradable plastic films show effects in the production of potatoes, peanuts and tobacco. Overall, a series of challenges has still been faced by the biodegradable plastic film, mainly including improving the quality of biodegradable plastic products, such as tensile strength, flexibility, improving the controllability of rupture and degradation, enhancing the ability of increasing soil temperature and preserving soil moisture, and to satisfy the demand of crops production with mulching. In addition, it is essential to reduce the cost of the biodegradable film and promote the application of biodegradable film on large-scale. With the development of biodegradable plastic technology and agricultural production environment, the application of the biodegradable film will have a good future.

NATURAL BASES AND ARTISTIC MEANS OF MODERN ARTS AND CRAFTS OF DAGESTAN

Full Text Available The aim is to carry out a generalized analysis of the history of formation of a new artistic language in contemporary arts and crafts of Dagestan. An innovative search for applied artist has gained further development in a series of works of the leading masters of folk arts and crafts of Dagestan. Discussion. For millennia, arts and crafts of Dagestan have been organically linked with the life of people and their everyday way of life and daily activities, with their worldview and understanding of beauty. In the middle of the 1st millennium BC in the mountainous Dagestan, art of bronze casting has reached a high degree of perfection, most vividly represented by statues of different wild and domestic animals. Images of animals are interpreted generically, without study of small details, but with the characteristic features of the exterior. Paired images of birds are often found in the arts and crafts of the medieval Dagestan. This heraldic composition, two-part or in conjunction with the sacred tree - a three-part, presented in metal-plastic and carved stone and wood, was one of the most popular and enduring decorative items that was common during the Middle Ages and has survived to the present day. This also has been further developed and improved and inherited by craftsmen of Dagestan.Conclusion. When creating works of arts and crafts craftsmen use diverse traditional arts and engineering techniques, the ancient but substantially revised and reinterpreted iconic scenes and ornamental motifs. In art, folk craftsmen emphasize the unity of man and nature. Most ornamental motifs common in Dagestan, go back to the very specific nature prototypes. Compositional structure, as the artistic analysis shows, is often borrowed from nature. This feeling becomes a condition for cultural and biological development, acting as a factor of co-evolution of man and nature.

Development of a new approach based on midwave infrared spectroscopy for post-consumer black plastic waste sorting in the recycling industry.

Science.gov (United States)

Rozenstein, Offer; Puckrin, Eldon; Adamowski, Jan

2017-10-01

Waste sorting is key to the process of waste recycling. Exact identification of plastic resin and wood products using Near Infrared (NIR, 1-1.7µm) sensing is currently in use. Yet, dark targets characterized by low reflectance, such as black plastics, are hard to identify by this method. Following the recent success of Midwave Infrared (MWIR, 3-12µm) measurements to identify coloured plastic polymers, the aim of this study was to assess whether this technique is applicable to sorting black plastic polymers and wood products. We performed infrared reflectance contact measurements of 234 plastic samples and 29 samples of wood and paper products. Plastic samples included black, coloured and transparent Polyethylene Terephthalate (PET), Polyethylene (PE), Polyvinyl Chloride (PVC), Polypropylene (PP), Polylactic acid (PLA) and Polystyrene (PS). The spectral signatures of the black and coloured plastic samples were compared with clear plastic samples and signatures documented in the literature to identify the polymer spectral features in the presence of coloured material. This information was used to determine the spectral bands that best suit the sorting of black plastic polymers. The main NIR-MWIR absorption features of wood, cardboard and paper were identified as well according to the spectral measurements. Good agreement was found between our measurements and the absorption features documented in the literature. The new approach using MWIR spectral features appears to be useful for black plastics as it overcomes some of the limitations in the NIR region to identify them. The main limitation of this technique for industrial applications is the trade-off between the signal-to-noise ratio of the sensor operating in standoff mode and the speed at which waste is moved under the sensor. This limitation can be resolved by reducing the system's spectral resolution to 16cm -1 , which allows for faster spectra acquisition while maintaining a reasonable signal-to-noise ratio

Computer simulation of plastic deformation in irradiated metals

International Nuclear Information System (INIS)

Colak, U.

1989-01-01

A computer-based model is developed for the localized plastic deformation in irradiated metals by dislocation channeling, and it is applied to irradiated single crystals of niobium. In the model, the concentrated plastic deformation in the dislocation channels is postulated to occur by virtue of the motion of dislocations in a series of pile-tips on closely spaced parallel slip planes. The dynamics of this dislocation motion is governed by an experimentally determined dependence of dislocation velocity on shear stress. This leads to a set of coupled differential equations for the positions of the individual dislocations in the pile-up as a function of time. Shear displacement in the channel region is calculated from the total distance traveled by the dislocations. The macroscopic shape change in single crystal metal sheet samples is determined by the axial displacement produced by the shear displacements in the dislocation channels. Computer simulations are performed for the plastic deformation up to 20% engineering strain at a constant strain rate. Results of the computer calculations are compared with experimental observations of the shear stress-engineering strain curve obtained in tensile tests described in the literature. Agreement between the calculated and experimental stress-strain curves is obtained for shear displacement of 1.20-1.25 μm and 1000 active slip planes per channel, which is reasonable in the view of experimental observations

Full Text Available Colour in variety of art expression can be interpreted differently. This study is aiming at analyzing the colour dematerialization of Javanese spiritual literature “Falsafah Jeroning Warna” by Suprapto Kadis and a painting by Ahmad Sadali entitled “Gunung Mas”. Research was done by employing qualitative research, while data was collected by observation, interview, discussion, and documentation study. The analysis of meanings in the two art works was done in descriptive way by using the theory and the knowledge of tasawwuf or sufism, the aesthetics, and arts. Results showed that both sufis, Ahmad Sadali and Suprapto Kadis, share similarities in doing dematerialization towards colour. For them, colour was initially taken from nature (the external territory which then experienced dematerialization when it made contact with inspiration that was created from the internal area (mental. On the other hand, the difference between the two art works lies on an understanding that colour in FJW is naturalistic mimesis in nature, meanwhile, the painting of Ahmad Sadali is naturaly abstract.

Plastics in the Marine Environment.

Law, Kara Lavender

2017-01-03

Plastics contamination in the marine environment was first reported nearly 50 years ago, less than two decades after the rise of commercial plastics production, when less than 50 million metric tons were produced per year. In 2014, global plastics production surpassed 300 million metric tons per year. Plastic debris has been detected worldwide in all major marine habitats, in sizes from microns to meters. In response, concerns about risks to marine wildlife upon exposure to the varied forms of plastic debris have increased, stimulating new research into the extent and consequences of plastics contamination in the marine environment. Here, I present a framework to evaluate the current understanding of the sources, distribution, fate, and impacts of marine plastics. Despite remaining knowledge gaps in mass budgeting and challenges in investigating ecological impacts, the increasing evidence of the ubiquity of plastics contamination in the marine environment, the continued rapid growth in plastics production, and the evidence-albeit limited-of demonstrated impacts to marine wildlife support immediate implementation of source-reducing measures to decrease the potential risks of plastics in the marine ecosystem.

Full Text Available Industrial solid waste (ISW is increasing in both quantity and complexity and it is a priority to establish strategies to manage it. Reverse Logistics (RL is a strategy that enables material recovery and reuse avoiding the damage that ISW may cause; also RL organizes solid waste management activities and supports other activities such as ISW trading. Most of the research linking ISW and RL in developed countries is related to the electronics subsector because of the negative effects on the environment; however, research oriented towards plastics subsector waste is lower. This is the case in Colombia where the plastics subsector is composed mainly by small and medium-sized enterprises (SMEs facing diverse constraints for their operation. Main facilitators and barriers that face SMEs in the Colombian plastics subsector to undertake RL programs were identified. An exploratory study was carried out in which business managers assessed the facilitators and barriers identified in the literature. The results showed that the availability of skilled people to perform RL activities is one of the most important internal facilitators and the lack of secondary markets for recovered materials is among the external barriers. The findings contribute to the body of knowledge in the field that is still maturing in Colombia.

The X-ray fluorescence method using a small source of 55 Fe was examined and found to be applicable for the selection of polychlorinated plastics from plastic waste in model areas in Tokyo designated for investigating their content in the waste. The weight ratios of soft and hard polychlorinated plastics to the total plastic waste estimated by this method were found to be 15.6% and 0.29% respectively. These values agree well with the results obtained with the Beilstein method. (author)

[Art-chance and art-experience in classical Greece].

Science.gov (United States)

Ban, Deokjin

2011-06-30

In Classical Greece, works defining the nature of art appeared in the various disciplines like medicine, rhetoric, dietetics, architecture and painting. Hippocratic authors tried to show that an art of medicine existed indeed. They contrasted the concept of art with that of chance, not experience that Plato and Aristotle distinguished from art. In fact there are similarities and discrepancies between Hippocratic epistemology and Platoic epistemology. Hippocratic authors maintained that the products of chance were not captured by art. They distinguished the domain of art charactered by explanatory knowledge and prediction from the domain of chance ruled by the unexplained and the unforeseeable. They minimized the role of luck and believed the role of art. Hippocratic authors thought that professional ability contained both knowledge and experience. In Hippocratic corpus, experience is a synonym of competence and usually has a positive meaning. But Plato gave empirical knowledge the disdainful sense and decided a ranking between two types of knowledge. Both Hippocratic authors and Plato held that a genuine art had connection with explanatory knowledge of the nature of its subject matter. A common theme that goes through arguments about art-chance and art-chance is the connection between art and nature. Hippocratic authors and Plato regarded art as a highly systematic process. Art provides us with general and explanatory knowledge of human nature. Art and nature is a mutual relationship. The systematic understanding of nature helps us gain the exactness of art and an exact art helps us understand nature well.

Since the beginning of civilization, the man has developed technologies to increase the efficiency of food production. The use of plastic mulch in commercial vegetable production is one of these traditional techniques that have been used for centuries. Studies were conducted to assess the efficacy of plastic mulch on growth and yield of two hot pepper hybrids, viz. Sky Red and Maha in poly/plastic tunnel. The treatments were black plastic mulch, clear plastic mulch and bare soil as control. Both hot pepper hybrids mulched with black plastic showed significantly better vegetative growth (plant height, leaf area etc) and fruit yield. Clear plastic mulch significantly increased soil temperature and reduced the number of days to first flower than black plastic mulch and bare soil. However, fruit yield was higher by 39.56 and 36.49% respectively in both hybrids when they were grown on black and clear plastic mulch as compared to bare soil. Overall results indicated that the use of plastic mulch is an ideal option to maximize hot pepper productivity as well as to extend their production season in poly/plastic tunnels. (author)

Interaction between vegetable oil based plasticizer molecules and polyvinyl chloride, and their plasticization effect

Plasticizer molecules are low molecular weight compounds that are widely used in polymer industries especially in polyvinyl chloride (PVC) resin. As an additive in PVC resin, the important role of plasticizer molecules is to improve the flexibility and processability of PVC by lowering the glass transition temperature (Tg). However, the commercial plasticizer like di(2-ethylhexyl)phthalate (DEHP) is known to cause liver cancer, at least in laboratory rats. DEHP can leach out from PVC into blood, certain drug solutions and fatty foods, which has been detected in the bloodstream of patients undergoing transfusion. Vegetable oil based plasticizers have some attractive properties such as non-toxic, bio-degradable, good heat and light stability, renewable resources, and environmentally friendly. Here we discussed the main results and development of vegetable oil based plasticizer, and especially palm oil based plasticizer. The interaction between plasticizer and polymer was discussed from the properties of the plasticized polymeric material.

Researchers suggest that integrating liberal arts into nursing education enhances student learning.

Reflection of Crusade Ideas in Medieval Art of 12* and 13* Centuries with Special Emphasis on Crusade Motives in Polish Art

Directory of Open Access Journals (Sweden)

Katarzyna Kabulak

2004-12-01

Full Text Available Literary inheritance of the Middle Ages has always been an invaluable source for researchers o f this epoch. It is the most valuable word for us. It needs to be mentioned, however, that a medieval recipient of literature was doubtlessly a member of a small elite. Few could claim to possess the ability to read and write. What appealed to the masses was an image – the most influential carrier of ideas. Wall paintings, sculptures, portals at the entrance to churches, coins with iconography best appealed to imagination. Symbolic representations affected the senses. “Pictorial system of communication played a role much more important for societies of the past than contemporary Polish historical literature acknowledges.” Touching upon a subject as vast as the crusade movement and the idea of fighting for every piece o f the Holy Land, one cannot let any information that was engraved or painted go unnoticed. Art, along site historical information, shows us a huge amount of propaganda material. Tiny details, the quality of outcome, the nicety of presentation are of no importance;what counts are the contents of depictions and the message. Art was therefore an educational factor used to show a certain model, in our considerations an ideal model, o f a Christ’s knight. The idea of crusades, both the Jerusalem crusade and the one broadly understood as a war against paganism, was also propagated through art.

Biodegradability standards for carrier bags and plastic films in aquatic environments: a critical review.

2018-05-01

Plastic litter is encountered in aquatic ecosystems across the globe, including polar environments and the deep sea. To mitigate the adverse societal and ecological impacts of this waste, there has been debate on whether 'biodegradable' materials should be granted exemptions from plastic bag bans and levies. However, great care must be exercised when attempting to define this term, due to the broad and complex range of physical and chemical conditions encountered within natural ecosystems. Here, we review existing international industry standards and regional test methods for evaluating the biodegradability of plastics within aquatic environments (wastewater, unmanaged freshwater and marine habitats). We argue that current standards and test methods are insufficient in their ability to realistically predict the biodegradability of carrier bags in these environments, due to several shortcomings in experimental procedures and a paucity of information in the scientific literature. Moreover, existing biodegradability standards and test methods for aquatic environments do not involve toxicity testing or account for the potentially adverse ecological impacts of carrier bags, plastic additives, polymer degradation products or small (microscopic) plastic particles that can arise via fragmentation. Successfully addressing these knowledge gaps is a key requirement for developing new biodegradability standard(s) for lightweight carrier bags.

Degradable plastics have been promoted as an option to mitigate the environmental impacts of plastic waste. However, there is no certainty about its degradability under different environmental conditions. The effect of accelerated weathering (AW), natural weathering (NW) and thermal oxidation (TO) on different plastics (high density polyethylene, HDPE; oxodegradable high density polyethylene, HDPE-oxo; compostable plastic, Ecovio ® metalized polypropylene, PP; and oxodegradable metalized polypropylene, PP-oxo) was studied. Plastics films were exposed to AW per 110 hours; to NW per 90 days; and to TO per 30 days. Plastic films exposed to AW and NW showed a general loss on mechanical properties. The highest reduction in elongation at break on AW occurred to HDPE-oxo (from 400.4% to 20.9%) and was higher than 90% for HDPE, HDPE-oxo, Ecovio ® and PP-oxo in NW. No substantial evidence of degradation was found on plastics exposed to TO. Oxo-plastics showed higher degradation rates than their conventional counterparts, and the compostable plastic was resistant to degradation in the studied abiotic conditions. This study shows that degradation of plastics in real life conditions will vary depending in both, their composition and the environment.

Methods of forming and patterning materials at the nano- and microscales are finding increased use as a medium of artistic expression, and as a vehicle for communicating scientific advances to a broader audience. While sharing many attributes of other art forms, miniaturized art enables the direct engagement of sensory aspects such as sight and touch for materials and structures that are otherwise invisible to the eye. The historical uses of nano-/microscale materials and imaging techniques in arts and sciences are presented. The motivations to create artwork at small scales are discussed, and representations in scientific literature and exhibitions are explored. Examples are presented using semiconductors, microfluidics, and nanomaterials as the artistic media; these utilized techniques including micromachining, focused ion beam milling, two-photon polymerization, and bottom-up nanostructure growth. Finally, the technological factors that limit the implementation of artwork at miniature scales are identified, and potential future directions are discussed. As research marches toward even smaller length scales, innovative and engaging visualizations and artistic endeavors will have growing implications on education, communication, policy making, media activism, and public perception of science and technology. © 2015 WILEY-VCH Verlag GmbH & Co.

2011-01-01

Methods for determination plasticity characteristic δH in the measurement of hardness and nanohardness are considered. Parameter δH characterizes the plasticity of a material by the part of plastic deformation in the total elastic-plastic deformation. The value of δH is defined for metals with different types of crystal lattice, covalent and partially covalent crystals, intermetallics, metallic glasses and quasicrystals. It is discussed the dependence of the plasticity characteristic δH on structural factors and temperature. Parameter δH allows to analyze and compare the plasticity of materials which are brittle at standard mechanical tests. The combination of hardness H, as the strength characteristic, and the plasticity characteristic δH makes possible the better characterization of mechanical behavior of materials than only the hardness H. The examples of plasticity characteristic δH application are represented.

Use of endochronic plasticity for multi-dimensional small and large strain problems

International Nuclear Information System (INIS)

Hsieh, B.J.

1980-04-01

The endochronic plasticity theory was proposed in its general form by K.C. Valanis. An intrinsic time measure, which is a property of the material, is used in the theory. the explicit forms of the constitutive equation resemble closely those of the classical theory of linear viscoelasticity. Excellent agreement between the predicted and experimental results is obtained for some metallic and non-metallic materials for one dimensional cases. No reference on the use of endochronic plasticity consistent with the general theory proposed by Valanis is available in the open literature. In this report, the explicit constitutive equations are derived that are consistent with the general theory for one-dimensional (simple tension or compression), two-dimensional plane strain or stress and three-dimensional axisymmetric problems

Bucknor, Alexandra; Kamali, Parisa; Phillips, Nicole; Mathijssen, Irene; Rakhorst, Hinne; Lin, Samuel J; Furnas, Heather

2018-06-01

Previous research has highlighted the gender-based disparities present throughout the field of surgery. This study aims to evaluate the breadth of the issues facing women in plastic surgery, worldwide. A systematic scoping review was undertaken from October of 2016 to January of 2017, with no restrictions on date or language. A narrative synthesis of the literature according to themed issues was developed, together with a summary of relevant numeric data. From the 2247 articles identified, 55 articles were included in the analysis. The majority of articles were published from the United States. Eight themes were identified, as follows: (1) workforce figures; (2) gender bias and discrimination; (3) leadership and academia; (4) mentorship and role models; (5) pregnancy, parenting, and childcare; (6) relationships, work-life balance, and professional satisfaction; (7) patient/public preference; and (8) retirement and financial planning. Despite improvement in numbers over time, women plastic surgeons continue to be underrepresented in the United States, Canada, and Europe, with prevalence ranging from 14 to 25.7 percent. Academic plastic surgeons are less frequently female than male, and women academic plastic surgeons score less favorably when outcomes of academic success are evaluated. Finally, there has been a shift away from overt discrimination toward a more ingrained, implicit bias, and most published cases of bias and discrimination are in association with pregnancy. The first step toward addressing the issues facing women plastic surgeons is recognition and articulation of the issues. Further research may focus on analyzing geographic variation in the issues and developing appropriate interventions.

Purpose: High dose rate (HDR) brachytherapy for treatment of small skin lesions using the Leipzig and Valencia applicators is a widely used technique. These applicators are equipped with an attachable plastic cap to be placed during fraction delivery to ensure electronic equilibrium and to prevent secondary electrons from reaching the skin surface. The purpose of this study is to report on the dosimetric impact of the cap being absent during HDR fraction delivery, which has not been explored previously in the literature. Methods: GEANT4 Monte Carlo simulations (version 10.0) have been performed for the Leipzig and Valencia applicators with and without the plastic cap. In order to validate the Monte Carlo simulations, experimental measurements using radiochromic films have been done. Results: Dose absorbed within 1 mm of the skin surface increases by a factor of 1500% for the Leipzig applicators and of 180% for the Valencia applicators. Deeper than 1 mm, the overdosage flattens up to a 10% increase. Conclusions: Differences of treating with or without the plastic cap are significant. Users must check always that the plastic cap is in place before any treatment in order to avoid overdosage of the skin. Prior to skin HDR fraction delivery, the timeout checklist should include verification of the cap placement.

Hanna, Gay Powell; Noelker, Linda S; Bienvenu, Beth

2015-04-01

In advance of the White House Conference on Aging (WHCoA) in 1981, 1995, and 2005, the arts and aging communities held mini-conferences to ensure that arts, culture, and livability were part of larger public policy discussions. This article takes a historical look at recommendations from the 2005 WHCoA Mini-Conference on Creativity and Aging in America, including arts in health care, lifelong learning, and livability through universal design. Overarching recommendations in 2005 requested investments in research, including cost-benefit analyses; identification of best practices and model programs; program dissemination to broaden the availability of arts programs. The "Arts" is a broad term encompassing all forms of arts including music, theater, dance, visual arts, literature, multimedia and design, folk, and traditional arts to engage the participation of all older Americans; promotion of innovative public and private partnerships to support arts program development, including workforce development (e.g., artists, social workers, and health care providers); and public awareness of the importance of arts participation to healthy aging. Through the leadership of the National Endowment for the Arts and U.S. Department of Health and Human Services, thinking about the arts and aging has broadened to include greater emphasis on a whole-person approach to the health and well-being of older adults. This approach engages older adults in arts participation not only as audience members, but as vital members of their community through creative expression focusing on life stories for intergenerational as well as interprofessional collaboration. This article reviews progress made to date and identifies critical gaps in services for future consideration at a 2015 Mini-Conference on Creativity and Aging related to the WCHoA area of emphasis on healthy aging. © The Author 2015.

Intrinsic Evaluation of n/γ Discrimination in Organic Plastic Scintillators

International Nuclear Information System (INIS)

Blanc, Pauline; Hamel, Matthieu; Rocha, Licinio; Normand, Stephane; Pansu, Robert; Gobert, Fabrice; Lampre, Isabelle

2013-06-01

This paper is devoted to characterizing plastic scintillators with neutron/gamma (n/γ) discrimination abilities and understanding experimentally the photophysical processes downstream. This experimental work is divided into two main studies, neutron sources irradiations and optical photoionization on a range of organic scintillators. The commercial liquid and plastic scintillators, respectively BC-501A from Bicron and EJ-200 from Eljen, are used as references in term of respectively extremely high [1] and poor n/γ discrimination efficiency, or more precisely Triplet-Triplet Annihilation rate probabilities after nuclear irradiations. We have characterized a range of organic plastic scintillators including one developed in our laboratory that shows good discrimination efficiency when compared to plastics that discriminate from literature. For that purpose we use the well known charge comparison as a pulse shape discrimination (PSD) method. We have also studied raw wave forms acquired after neutron irradiation before any kind of treatment was applied and managed to separate two light components, prompt and delayed, thus two particle families. We have demonstrated that by exciting with a 70 femto-seconds pulsed Laser at the femtosecond up to 50 μJ at 260 nm, photoionization was achieved for a range of organic scintillators by observing a delayed light emission in the time decay fluorescence when the Laser energy deposited in the materials was increased. This work is ongoing at CEA in collaboration with the nuclear measurement industry Canberra and the Laboratoire de Chimie Physique from Orsay University. (authors)

The use of live and cadaveric animal models in surgical training is well established as a means of teaching and improving surgical skill in a controlled setting. We aim to review, evaluate, and summarize the models published in the literature that are applicable to Plastic Surgery training. A PubMed search for keywords relating to animal models in Plastic Surgery and the associated procedures was conducted. Animal models that had cross over between specialties such as microsurgery with Neurosurgery and pinnaplasty with ear, nose, and throat surgery were included as they were deemed to be relevant to our training curriculum. A level of evidence and recommendation assessment was then given to each surgical model. Our review found animal models applicable to plastic surgery training in four major categories namely-microsurgery training, flap raising, facial surgery, and hand surgery. Twenty-four separate articles described various methods of practicing microsurgical techniques on different types of animals. Fourteen different articles each described various methods of conducting flap-based procedures which consisted of either local or perforator flap dissection. Eight articles described different models for practicing hand surgery techniques. Finally, eight articles described animal models that were used for head and neck procedures. A comprehensive summary of animal models related to plastic surgery training has been compiled. Cadaveric animal models provide a readily available introduction to many procedures and ought to be used instead of live models when feasible. Copyright © 2017 Elsevier Inc. All rights reserved.

Nano-Ceramic Coated Plastics

Science.gov (United States)

Cho, Junghyun

2013-01-01

Plastic products, due to their durability, safety, and low manufacturing cost, are now rapidly replacing cookware items traditionally made of glass and ceramics. Despite this trend, some still prefer relatively expensive and more fragile ceramic/glassware because plastics can deteriorate over time after exposure to foods, which can generate odors, bad appearance, and/or color change. Nano-ceramic coatings can eliminate these drawbacks while still retaining the advantages of the plastic, since the coating only alters the surface of the plastic. The surface coating adds functionality to the plastics such as self-cleaning and disinfectant capabilities that result from a photocatalytic effect of certain ceramic systems. These ceramic coatings can also provide non-stick surfaces and higher temperature capabilities for the base plastics without resorting to ceramic or glass materials. Titanium dioxide (TiO2) and zinc oxide (ZnO) are the candidates for a nano-ceramic coating to deposit on the plastics or plastic films used in cookware and kitchenware. Both are wide-bandgap semiconductors (3.0 to 3.2 eV for TiO2 and 3.2 to 3.3 eV for ZnO), so they exhibit a photocatalytic property under ultraviolet (UV) light. This will lead to decomposition of organic compounds. Decomposed products can be easily washed off by water, so the use of detergents will be minimal. High-crystalline film with large surface area for the reaction is essential to guarantee good photocatalytic performance of these oxides. Low-temperature processing (nano-ceramic coatings (TiO2, ZnO) on plastic materials (silicone, Teflon, PET, etc.) that can possess both photocatalytic oxide properties and flexible plastic properties. Processing cost is low and it does not require any expensive equipment investment. Processing can be scalable to current manufacturing infrastructure.

1992-01-01

A one-parameter plasticity model was shown to adequately describe the plastic deformation of AS4/PEEK (APC-2) unidirectional thermoplastic composite. This model was verified further for unidirectional and laminated composite panels with and without a hole. The elastic-plastic stress-strain relations of coupon specimens were measured and compared with those predicted by the finite element analysis using the one-parameter plasticity model. The results show that the one-parameter plasticity model is suitable for the analysis of elastic-plastic deformation of AS4/PEEK composite laminates.

The performance of molded plastic scintillators is studied. The plastic scintillators studied were formed by transfer molding and intrusion from a scintillation composition consisting of polystyrene and a standard system of luminescent additives: 2 mass % of paraterphenyl + 0.06 mass % 1,4-di-/2-[5-phenyloxazoyly]/benzene and a plasticizer. The combined effect of mechanical load and temperature was studied. The effect of radiation on molded plastic scintillators was studied using gamma radiation from a 60 Co source. The studies show that the main operating characteristics of molded plastic scintillators are on a par with those of polymerized plastic scintillators. At the same time, molded plastic scintillators are superior in thermal stability at temperatures below the glass transition temperature and with respect to their working temperature range

Plastic food packaging and health

Full Text Available Plastics have a wide usage in our daily lives. One of their uses is for food packaging and food containers. The aim of this review is to introduce different types of chemicals that can leach from food packaging plastics into foods and cause human exposure and to mention their effects on health. The types of plastics were reviewed under the 13 headings in Turkish Codex Alimentarius and plastics recycling symbols were provided to enable the recognition of the type of plastic when applicable. Chemicals used during the production and that can cause health risks are investigated under the heading of the relevant type of plastic. The most important chemicals from plastic food packaging that can cause toxicity are styrene, 1,3-butadiene, melamine, formaldehyde, acrylamide, di-2-ethylhexyl phthalate, di-2-ethylhexyl adipate, vinyl chloride and bisphenol A. These chemicals have endocrine disrupting, carcinogenic and/or development disrupting effects. These chemicals may leach into foods depending on the chemical properties of the plastic or food, temperature during packaging, processing and storage, exposure to UV and duration of storage. Contact with fatty/oily or acidic foods, heating of the food inside the container, or drinking hot drinks from plastic cups, use of old and scratched plastics and some detergents increase the risk of leaching. The use of plastic containers and packaging for food and beveradges should be avoided whenever possible and when necessary, less harmful types of plastic should be preferred.

The beneficial attributes of visual art-making in cancer care: An integrative review.

Ennis, G; Kirshbaum, M; Waheed, N

2018-01-01

We seek to understand what is known about the use of visual art-making for people who have a cancer diagnosis, and to explore how art-making may help address fatigue in the cancer care context. Art-making involves creating art or craft alone or in a group and does not require an art-therapist as the emphasis is on creativity rather than an overt therapeutic intention. An integrative review was undertaken of qualitative, quantitative and mixed-method studies on art-making for people who have cancer, at any stage of treatment or recovery. An adapted version of Kaplan's Attention Restoration Theory (ART) was used to interpret the themes found in the literature. Fifteen studies were reviewed. Nine concerned art-making programmes and six were focused on individual, non-facilitated art-making. Review results suggested that programme-based art-making may provide participants with opportunities for learning about self, support, enjoyment and distraction. Individual art-making can provides learning about self, diversion and pleasure, self-management of pain, a sense of control, and enhanced social relationships. When viewed through the lens of ART, art-making can be understood as an energy-restoring activity that has the potential to enhance the lives of people with a diagnosis of cancer. © 2017 John Wiley & Sons Ltd.

Full Text Available In the article the modern tendencies of using integrative approach to organizing art teachers’ instrumental and performing training. The concept “integration” is singled out; it is defined as the process of recovery, replenishment, combining previously isolated parts; moving of the system to a great organic integrity. It is disclosed that the integration means considering multidimensionality of element features which are being integrated while accumulating quantitative features and emerging a new quality and individual features of integral elements are saved. It is proved that integrating is interrelation of art varieties in the process of their aesthetic and educational impact on pupils that is the whole perception of a work (its content and its emotional, rational, ethical and aesthetic form in the unity of tasks of developing artistic and aesthetic senses, thoughts, tastes and pupils’ ideals. It is thought that integration in art pedagogy is held at three levels: internal artistic and aesthetic synthesis of various arts organically combined with students creative activity; interdisciplinary humanistic synthesis of the arts, the native language, literature, and folklore; looking for semantic blocks, images, concepts that have universal meaning, which, entering all spheres of human consciousness, such as science and mathematics, seamlessly combining them into a coherent system. It is noted that the most efficient approach is appeal to the learning subjects of Humanities cycle – music, literature and art. It is concluded that designing of training should be started with the analyzing prospective art teacher’s activity. It should be understood what the teacher has to do, not in general formulation, but at the level of actions and operations.

Interpreting map art with a perspective learned from J.M. Blaut

Science.gov (United States)

Varanka, D.

2006-01-01

Map art has been mentioned only briefly in geographic or cartographic literature, and has been analyzed almost entirely at the interpretive level. This paper attempts to define and evaluate the cartographic value of contemporary map-like art by placing the body of work as a whole in the theoretical concepts proposed by J.M. Blaut and his colleagues about mapping as a cognitive and cultural universal. This paper discusses how map art resembles mapping characteristics similar to those observed empirically in very young children as described in the publications of Blaut and others. The theory proposes that these early mapping skills are later structured and refined by their social context and practice. Diverse cultural contexts account for the varieties, types, and degrees of mapping behavior documented with time and geographic place. The dynamics of early mapping are compared to mapping techniques employed by artists. The discipline of fine art serves as the context surrounding map artists and their work. My visual analysis, research about the art and the artists, and interviews with artists and curators form the basis of my interpretation of these works within varied and multiple contexts of late 20th century map art.

Ancestral diet leads to dynamic transgenerational plasticity for five generations in Drosophila melanogaster

OpenAIRE

Mikheyev, Alexander; Emborski, Carmen

2018-01-01

Ancestral exposures can influence phenotypic expression in subsequent generations, which influence diverse biological processes ranging from phenotypic plasticity to obesity. Currently, most transgenerational studies work under the assumption of transgenerational response stability and reproducibility through time and across exposure differences, relying on short-term (i.e. 2-3 generations) single-exposure experiments. Yet, little evidence exists in the literature to validate this assumption,...

Participatory arts and affective engagement with climate change: The missing link in achieving climate compatible behaviour change?

OpenAIRE

Burke, Miriam; Ockwell, David; Whitmarsh, Lorraine

2018-01-01

Despite a growing number of arts based climate change interventions and the importance emphasised in the social psychology literature of achieving affective (emotional) engagement with climate change before climate compatible behaviour change is likely (exactly the kind of engagement the arts and humanities are arguably best at), to date there has been no systematic application of interpretive social science techniques to understand the ways in which these arts based interventions do, or do n...

Synaptic plasticity is one of the fields that progresses rapidly and has a lot of success in neuroscience. The two major types of synaptie plasticity: long-term potentiation ( LTP and long-term depression (LTD are thought to be the cellular mochanisms of learning and memory. Recently, accumulating evidence suggests that, besides serving as a cellular model for learning and memory, the synaptic plasticity involves in other physiological or pathophysiological processes, such as the perception of pain and the regulation of cardiovascular system. This minireview will focus on the relationship between synaptic plasticity and nociception.

Choudry, Umar; Barta, Ruth J; Kim, Nicholas

2013-06-01

There is a paucity of literature regarding the use of chaperones by surgeons when examining patients. Use of a chaperone not only makes the patient comfortable but also potentially protects the surgeon from perceived misconduct. This is especially true for plastic surgeons who examine sensitive areas commonly. The purpose of this study was to determine the current trends in chaperone use by plastic surgeons when examining patients. A 23-question online survey was sent to all members of the American Society of Plastic Surgeons. Data collected online were analyzed using Student t test and Pearson χ test. A P use by plastic surgeons during all examinations of patients was 30%. This rate increased up to 60% while examining sensitive areas. Male surgeons reported a higher frequency of chaperone use than female surgeons (P use compared to reconstructive surgeons (P = 0.001). Similarly, surgeons who had been in practice for more than 20 years reported a higher rate of chaperone use compared to surgeons in practice for less than 20 years (P = 0.032). Sixty-one (7.6%; 56 male and 5 female) surgeons reported being accused of inappropriate behavior by patients, of whom 49 (80%) did not have a chaperone present. There was no significant difference among male and female surgeons in rates of being accused of inappropriate behavior (7.9% vs 4.2%, P = 0.19). There was a higher rate of chaperone use by male plastic surgeons, surgeons with more than 20 years experience, and cosmetic surgeons. Despite the difference in chaperone use between the sexes, both had similar rates of being accused of inappropriate behavior during examinations by patients, and although these incidents were quite low, most had no chaperone present during those examinations.

Leadership in literature.

Science.gov (United States)

2006-03-01

Business students nowadays are not, for the most part, poets. A growing proportion come to business school with a background in investment banking or management consulting and an undergraduate business major, rather than a degree in the arts and sciences. MBA students are already very familiar with business. A number of scholars and businesspeople have begun to question the scientific model that dominates business research and teaching. Formalized management tools work well enough if you're studying techniques for financial valuation, but less so when you're studying leadership and organizational behavior. Some argue that students could learn a lot more about these subjects if they took a course in literature. Examples from fiction can be as instructive as any business textbook. HBR senior editor Diane Coutu recently met with Joseph Badaracco, Jr., for a wide-ranging discussion of what leaders can learn from literature. For the past decade, Badaracco, the John Shad Professor of Business Ethics at Harvard Business School, has used classical literature to provide well-rounded, complex pictures of leaders in all walks of life-particularly leaders whose psychological and emotional challenges parallel those of senior executives. Fiction provides some of the most powerful and engaging case studies ever written. Unlike contemporary management literature, which is relentlessly upbeat, classical literature is unsparingly realist. Leaders often struggle and sometimes fail-and the stakes are high. When business leaders read about the conflicts of literary characters, they can better understand their own circumstances. We pay far too little attention to the inner lives of leaders. Business school courses seem to suggest that you can treat executives like lab animals and control their behavior through their environment. But behaviorism is not enough. Literature suggests that leaders should learn more about themselves if they want to succeed.

MARKETING – A WAY TO INCREASE THE VALUE OF THE PERFORMING ARTS

Full Text Available Several studies have focused on the marketing mix of goods, but it shouldn’t be neglected that services, through its characteristics, cause major problems for marketers, when adopting appropriate marketing strategies. This problem is prevalent in the field of cultural services, where marketers face the lack of funds to implement appropriate marketing strategies, either an internal system that restricts the possibilities for action, or simply a lack of experience and marketing information applied within cultural services. The purpose of this study is to compress information regarding the characteristics of cultural services and the specific marketing actions used in the field of performing arts, providing thus several directions in knowing and understanding it. Many cultural institutions are still adopting traditional marketing strategies but this approach is not sufficient. New approaches and strategies are required in order to ensure their survival on the cultural market. This paper offers for the reader a literature review of arts marketing and the main issues approached in specialized literature regarding marketing in performing arts. Several ideas based on this survey are formulated in order to improve the marketing strategies adopted by cultural institutions.

2018-04-01

One of natural polymers that can be used as raw material in the manufacture of biodegradable plastic is tapioca and chitosan. The addition of other compounds such as glycerol as plasticizer is to improve the characteristics of the plastic that already produced. N- Isopropylacrylamid (NIPAm) is an organic compound that can be synthesized into a polymer or polymer grafting which also biodegradable too. This research aims tostudy the synthesis of biodegradable plastics from tapioca with the addition of chitosan, NIPAm, poly(NIPAm) and analyze the characteristics of biodegradable plastics that already produced. This research was done in three stages, there are (1) polymerization NIPAm, (2) the grafting of chitosan-poly NIPAm and (3) the synthesis of biodegradable plastics from starch mixture with variation of addition chitosan, NIPAm, poly(NIPAm), chitosan-graft-poly(NIPAm) and also variations of glycerol as plasticizer. The results of this research is a thin sheet of plastic which is will get analyzed for the characteristics of functional groups, mechanical, morphological and its biodegradability. FTIR spectra showed the grafting process with the new group formation of CO single-bond at 850 cm-1. Plastic with the addition of NIPAm and 1 ml glycerol has the highest tensile strength value about 31.1 MPa. Plastic with poly(NIPAm) and 4 ml glycerol produces the highest elongation value about 153.72%. Plastic with Chitosan-graft-poly(NIPAm) with 1 ml glycerol has the longest biodegradation because of the small mass-loss for six weeks which is about 6.6%.

New perspectives in plastic biodegradation.

Sivan, Alex

During the past 50 years new plastic materials, in various applications, have gradually replaced the traditional metal, wood, leather materials. Ironically, the most preferred property of plastics--durability--exerts also the major environmental threat. Recycling has practically failed to provide a safe solution for disposal of plastic waste (only 5% out of 1 trillion plastic bags, annually produced in the US alone, are being recycled). Since the most utilized plastic is polyethylene (PE; ca. 140 million tons/year), any reduction in the accumulation of PE waste alone would have a major impact on the overall reduction of the plastic waste in the environment. Since PE is considered to be practically inert, efforts were made to isolate unique microorganisms capable of utilizing synthetic polymers. Recent data showed that biodegradation of plastic waste with selected microbial strains became a viable solution. Copyright © 2011 Elsevier Ltd. All rights reserved.

Avalanches and plastic flow in crystal plasticity: an overview

Science.gov (United States)

Papanikolaou, Stefanos; Cui, Yinan; Ghoniem, Nasr

2018-01-01

Crystal plasticity is mediated through dislocations, which form knotted configurations in a complex energy landscape. Once they disentangle and move, they may also be impeded by permanent obstacles with finite energy barriers or frustrating long-range interactions. The outcome of such complexity is the emergence of dislocation avalanches as the basic mechanism of plastic flow in solids at the nanoscale. While the deformation behavior of bulk materials appears smooth, a predictive model should clearly be based upon the character of these dislocation avalanches and their associated strain bursts. We provide here a comprehensive overview of experimental observations, theoretical models and computational approaches that have been developed to unravel the multiple aspects of dislocation avalanche physics and the phenomena leading to strain bursts in crystal plasticity.

Prevalence of Body Dysmorphic Disorder in Plastic Surgery and Dermatology Patients: A Systematic Review with Meta-Analysis.

Science.gov (United States)

Ribeiro, Rafael Vilela Eiras

2017-08-01

The aim of the present study was to evaluate the prevalence of body dysmorphic disorder in plastic surgery and dermatology patients, by performing a systematic review of the literature and meta-analysis. The most relevant studies published originally in any language were analyzed. The literature search was performed using the PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), and Scielo databases. The final sample comprised 33 publications that were submitted to meta-analysis. The study verified that 15.04% of plastic surgery patients had body dysmorphic disorder (range 2.21-56.67%); patient mean age was 34.54 ± 12.41 years, and most were women (74.38%). Among dermatology patients, 12.65% (range 4.52-35.16%) had body dysmorphic disorder; patient mean age was 27.79 ± 9.03 years, and most were women (76.09%). Both plastic surgeons and dermatologists must adequately assess their patients to identify those with a higher likelihood of body dysmorphic disorder and should arrange multidisciplinary care for such individuals. This journal requires that authors assign a level of evidence to each article.

O'Hanlon, Nina J; James, Neil A; Masden, Elizabeth A; Bond, Alexander L

Marine plastic pollution is an increasing, and global, environmental issue. Numerous marine species are affected by plastic debris through entanglement, nest incorporation, and ingestion, which can lead to lethal and sub-lethal impacts. However, in the northeastern Atlantic Ocean, an area of international importance for seabirds, there has been little effort to date to assess information from studies of wildlife and plastic to better understand the spatiotemporal variation of how marine plastic affects different seabird species. To improve our understanding of seabirds and marine plastic in this region, we completed a synthesis of the published and grey literature to obtain information on all known documented cases of plastic ingestion and nest incorporation by this group. We found that of 69 seabird species that commonly occur in the northeastern Atlantic, 25 had evidence of ingesting plastic. However, data on plastic ingestion was available for only 49% of all species, with 74% of investigated species recorded ingesting plastic. We found only three published studies on nest incorporation, for the Northern Gannet (Morus bassanus) and Black-legged Kittiwake (Rissa tridactyla). For many species, sample sizes were small or not reported, and only 39% of studies were from the 21st century, whilst information from multiple countries and years was only available for 11 species. This indicates that we actually know very little about the current prevalence of plastic ingestion and nest incorporation for many species, several of them globally threatened. Furthermore, in the majority of studies, the metrics reported were inadequate to carry out robust comparisons among locations and species or perform meta-analyses. We recommend multi-jurisdictional collaboration to obtain a more comprehensive and current understanding of how marine plastic is affecting seabirds in the northeastern Atlantic Ocean.
