The narcissism and death of Yukio Mishima--from the object relational point of view.

Science.gov (United States)

Ushijima, S

1987-12-01

The author discussed the life and work of Yukio Mishima from the object relational point of view. First, he described his brief life history, pointing out the four big identity crises in his life as his fierce struggles against the suicidal wishes were likely to enlarge within himself. Then, he suggested that Mishima had been in the state of part object relationship throughout his life. Thirdly, the important role of the body or bodies in his fantastic and real life was discussed as a manifestation of not merely autoerotic activities but also disturbances of the core of identity. Finally, the fragility of the intermediate area of experience which was thought to have eventually led him to the last action, the seppuku, was examined.

Psychotrichology is the science, which covers the psychosomatics applied to hair problems, i.e., body-psyche phenomena involving scalp and hair disorders. The approaches involving psychotricology are varied and may include psychiatric,[1] psychoanalytical,[23] and those involving knowledge related to analytical psychology.[4] An analysis from the analytical psychology point of view, a theory developed by the physician Carl Gustav Jung, favors a symbolic view to the disease, providing it attributions and meanings that go beyond those related to physical body signs and symptoms only. This paper aims to describe and analyze, under the analytical psychology view, three cases the psychic and clinical demonstrations of which relate to symbolic and historic aspects concerning life of patients as possibilities of cause and maintenance of hair problems. The first of them is related to an 8-year-old girl who witnessed a scene of physical aggression by her father against her mother and developed a case of total alopecia. The second case is related to a 43-year-old woman who developed self-inflicted scalp dermatitis due to severe anxiety; and at last, the case of a telogen effluvium in a 23-year-old woman who developed hyperprolactinemia after the death of her mother, having to substitute her in the care about her husband and brothers. Looking at the clinical history and symbolic matters of scalp and hair diseases enabled, in the aforementioned cases, a better understanding of patients' psychoemotional disorders that may be related to the beginning and maintenance of clinical cases presented by them.

Unlike conventional scalar sensors, camera sensors at different positions can capture a variety of views of an object. Based on this intrinsic property, a novel model called full-view coverage was proposed. We study the problem that how to select the minimum number of sensors to guarantee the full-view coverage for the given region of interest (ROI). To tackle this issue, we derive the constraint condition of the sensor positions for full-view neighborhood coverage with the minimum number of nodes around the point. Next, we prove that the full-view area coverage can be approximately guaranteed, as long as the regular hexagons decided by the virtual grid are seamlessly stitched. Then we present two solutions for camera sensor networks in two different deployment strategies. By computing the theoretically optimal length of the virtual grids, we put forward the deployment pattern algorithm (DPA) in the deterministic implementation. To reduce the redundancy in random deployment, we come up with a local neighboring-optimal selection algorithm (LNSA) for achieving the full-view coverage. Finally, extensive simulation results show the feasibility of our proposed solutions. PMID:28587304

Local or district heating by natural gas: Which is better from energetic, environmental and economic point of views?

International Nuclear Information System (INIS)

Lazzarin, R.; Noro, M.

2006-01-01

Generally, a CHP plant coupled with district heating is considered more efficient than traditional local heating systems from an economic and environmental point of view. This is certainly true for municipal waste CHP plants, but for plants fuelled by natural gas the important developments of the last years regarding both boilers (premixed and modulating burners, condensing boilers, etc.) and mechanical vapour compression and absorption heat pumps can change the traditional view. At the same time also district heating plants improved. Therefore it is worth to analyse the whole matter comparing advantages and disadvantages of the different alternatives, with a wide difference between them. The paper reports on the analysis of major district heating natural gas based technologies (vapour and gas turbines, internal combustion engine, combined cycles); the cost of heat and power produced in these plants is compared to the cost of producing the same quantity of electrical energy by a reference GTCC-Gas Turbine Combined Cycle (actually the most efficient technology for pure electrical production) and the cost of heat production by modern local heating technologies using natural gas as fuel (condensing boilers, electrical, gas engine and absorption heat pumps). Regarding energy efficiency and emissions, modern local heating turns out to be more efficient than district heating for most CHP technologies. However, the same does not happen from an economic point of view, because in Italy natural gas used by cogeneration plants is subjected to a much lower taxation than local heating technologies

The documents used as the sources of this study are the ones with complete pictures and strong narration on Javanese recorded from Han Dynasty (206 bc–220 ad to Ming Dynasty (1364–1644 in order to reveal what kind of historical knowledge or historical information is delivered by Chinese historians in general and what kind of point of view is used by historians to deliver the notes about Java. Through analytical reading, the readers will find that historians paid attention to three issues: the relationship between China and Java, the condition of Javanese kingdoms and their culture, and the Java land natural resources. People of China regard their country as an ancient country with long history of remarkable civilization which located in the centre of the world. The awareness of how important is their country, indirectly influences the historians’ points of views. The texts analyzed indirectly prove that some areas on Java are culturally left behind and the countries beyond China, including Java, are the barbaric ones obliging their people to submit or pay tributes to the Kingdoms of China.

Full Text Available Psychotherapy is a general name of interventions used to resolve emotional conflicts, support and sustain the improvement of mental health. Relationship is one of the most important factors of regenerative effect in psychotherapy. Understanding the client is crucial to help the client understand the psychotherapy and psychotherapist. Thus, in order to be effective in psychotherapeutic interventions, it is neccessary to use the language by considering the client’s believes, culture, religion and background. Comprehending and using of psychotherapy only from the Western point of view could reduce the efficacy of psychotherapy. Although, it is common that people working in mental health area learn and use the techniques of authorities lived in West, our culture is considerably wealthy of thoughts and aspects that can be used in psychotherapy. Raised on the lands that have extremely rich cultural heritage, as psychotherapists, we think that it is our responsibility to integrate modern psychotherapy with cultural heritage when learning, practicing and teaching the practice of psychotherapy. In this article, it is aimed to increase the awareness of being able to use the philosophy of Mevlana Celaleddin Rumi whose masterpieces involve psychotherapeutic elements yet are not well understood and who has been an inspration to the trends in psychotherapy which are currently described as third generation trends.

All versions of nuclear reactors present favourable and unfavourable characteristics from the point of view of safety. The safety of the installations is obtained by making efforts to utilize in the best possible way those which are favourable and by taking proper steps in the face of those which are unfavourable. The present article shows how this general principle has been applied as regards the fast neutron reactors of integrated design which have been developped in France, taking into account the specific features of this version. A qualitative method to compare the safety of this version with that of pressurized water reactors which has been widely put to the test commercially all over the world is presented. These analyses make, generally speaking, several positive characteristics stand out for these fast neutron reactors from the safety aspects [fr

The Origin of Life from the Astrophysical Point of View

Science.gov (United States)

Yeghikyan, Ararat

2017-11-01

Тhe problem of the origin of life is discussed from the astrophysical point of view. Most biologists and geologists up to the present time believe that Life was originated on the Earth in some initial natural chemical pre-reactors, where a mixture of water, ammonia, methane containing species and some other substances, under the influence of an energy source like, e.g. lightning, turned into quite complex compounds such as amino acids and complex hydrocarbons. In fact, under conditions of the primordial Earth, it is not possible to obtain such pre-biological molecules by a-bio-chemical methods, as discussed in this lecture. Instead, an astrophysical view of the problem of the origin of life on the Earth is proposed and it is recalled that the biological evolution on the Earth was preceded by the chemical evolution of complex chemical compounds, mostly under extraterrestrial conditions, where it is only possible to form optically active amino acids, sugars and hydrocarbon is necessary for constructing the first pre-biomolecules .

Fluid Mechanics: A Geometrical Point of View emphasizes general principles of physics illustrated by simple examples in fluid mechanics. Advanced mathematics (e.g., Riemannian geometry and Lie groups) commonly used in other parts of theoretical physics (e.g. General Relativity or High Energy Physics) are explained and applied to fluid mechanics. This follows on from the author's book Advanced Mechanics (Oxford University Press, 2013). After introducing the fundamental equations (Euler and Navier-Stokes), the book provides particular cases: ideal and viscous flows, shocks, boundary layers, instabilities, and transients. A restrained look at integrable systems (KdV) leads into a formulation of an ideal fluid as a hamiltonian system. Arnold's deep idea, that the instability of a fluid can be understood using the curvature of the diffeomorphism group, will be explained. Leray's work on regularity of Navier-Stokes solutions, and the modern developments arising from it, will be explained in language for physicists...

Full Text Available Shoulder line is the significant line in hilly area of Loess Plateau in China, dividing the surface into positive and negative terrain (P-N terrains. Due to the point cloud vegetation removal methods of P-N terrains are different, there is an imperative need for shoulder line extraction. In this paper, we proposed an automatic shoulder line extraction method based on point cloud. The workflow is as below: (i ground points were selected by using a grid filter in order to remove most of noisy points. (ii Based on DEM interpolated by those ground points, slope was mapped and classified into two classes (P-N terrains, using Natural Break Classified method. (iii The common boundary between two slopes is extracted as shoulder line candidate. (iv Adjust the filter gird size and repeat step i-iii until the shoulder line candidate matches its real location. (v Generate shoulder line of the whole area. Test area locates in Madigou, Jingbian County of Shaanxi Province, China. A total of 600 million points are acquired in the test area of 0.23km2, using Riegl VZ400 3D Laser Scanner in August 2014. Due to the limit Granted computing performance, the test area is divided into 60 blocks and 13 of them around the shoulder line were selected for filter grid size optimizing. The experiment result shows that the optimal filter grid size varies in diverse sample area, and a power function relation exists between filter grid size and point density. The optimal grid size was determined by above relation and shoulder lines of 60 blocks were then extracted. Comparing with the manual interpretation results, the accuracy of the whole result reaches 85%. This method can be applied to shoulder line extraction in hilly area, which is crucial for point cloud denoising and high accuracy DEM generation.

An integrative relational point of view.

Science.gov (United States)

Wachtel, Paul L

2014-09-01

This article, part of a special section on the Relational Foundations of Psychotherapy, describes a particular relational approach called cyclical psychodynamics. Cyclical psychodynamics is rooted both in the relational perspective in psychoanalysis and in an integrative melding of psychodynamic, cognitive-behavioral, systemic, and experiential points of view. Central to its theoretical structure is a focus on the vicious and virtuous circles that perpetuate (or contribute to changing) personality patterns that may have originated in childhood but that persist because they often generate the very feedback from others that is necessary to keep them going. As a consequence of this latter focus, the relational foundation of cyclical psychodynamic therapy addresses in equal and dynamically reciprocal fashion both the therapeutic relationship in the consulting room and the key relationships outside the consulting room that play an essential role in the maintenance or change of the problematic patterns the person has come to therapy to work on.

Exploring point-cloud features from partial body views for gender classification

Fouts, Aaron; McCoppin, Ryan; Rizki, Mateen; Tamburino, Louis; Mendoza-Schrock, Olga

2012-06-01

In this paper we extend a previous exploration of histogram features extracted from 3D point cloud images of human subjects for gender discrimination. Feature extraction used a collection of concentric cylinders to define volumes for counting 3D points. The histogram features are characterized by a rotational axis and a selected set of volumes derived from the concentric cylinders. The point cloud images are drawn from the CAESAR anthropometric database provided by the Air Force Research Laboratory (AFRL) Human Effectiveness Directorate and SAE International. This database contains approximately 4400 high resolution LIDAR whole body scans of carefully posed human subjects. Success from our previous investigation was based on extracting features from full body coverage which required integration of multiple camera images. With the full body coverage, the central vertical body axis and orientation are readily obtainable; however, this is not the case with a one camera view providing less than one half body coverage. Assuming that the subjects are upright, we need to determine or estimate the position of the vertical axis and the orientation of the body about this axis relative to the camera. In past experiments the vertical axis was located through the center of mass of torso points projected on the ground plane and the body orientation derived using principle component analysis. In a natural extension of our previous work to partial body views, the absence of rotational invariance about the cylindrical axis greatly increases the difficulty for gender classification. Even the problem of estimating the axis is no longer simple. We describe some simple feasibility experiments that use partial image histograms. Here, the cylindrical axis is assumed to be known. We also discuss experiments with full body images that explore the sensitivity of classification accuracy relative to displacements of the cylindrical axis. Our initial results provide the basis for further

Various classification methods are available that can be used to delineate land cover types. Object-based is one of such methods for delineating the land cover from satellite imageries. This paper focuses on the digital image processing aspects of discriminating wetland areas via object-based method using high resolution satellite multispectral WorldView-2 image data taken over part of Penang Island region. This research is an attempt to improve the wetland area delineation in conjunction with a range of classification techniques which can be applied to satellite data with high spatial and spectral resolution such as World View 2. The intent is to determine a suitable approach to delineate and map these wetland areas more appropriately. There are common parameters to take into account that are pivotal in object-based method which are the spatial resolution and the range of spectral channels of the imaging sensor system. The preliminary results of the study showed object-based analysis is capable of delineating wetland region of interest with an accuracy that is acceptable to the required tolerance for land cover classification

Numbers and functions from a classical-experimental mathematician's point of view

CERN Document Server

Moll, Victor H

2012-01-01

New mathematics often comes about by probing what is already known. Mathematicians will change the parameters in a familiar calculation or explore the essential ingredients of a classic proof. Almost magically, new ideas emerge from this process. This book examines elementary functions, such as those encountered in calculus courses, from this point of view of experimental mathematics. The focus is on exploring the connections between these functions and topics in number theory and combinatorics. There is also an emphasis throughout the book on how current mathematical software can be used to discover and prove interesting properties of these functions. The book provides a transition between elementary mathematics and more advanced topics, trying to make this transition as smooth as possible. Many topics occur in the book, but they are all part of a bigger picture of mathematics. By delving into a variety of them, the reader will develop this broad view. The large collection of problems is an essential part of...

AN ACCURACY ASSESSMENT OF GEOREFERENCED POINT CLOUDS PRODUCED VIA MULTI-VIEW STEREO TECHNIQUES APPLIED TO IMAGERY ACQUIRED VIA UNMANNED AERIAL VEHICLE

2012-08-01

Full Text Available Low-cost Unmanned Aerial Vehicles (UAVs are becoming viable environmental remote sensing tools. Sensor and battery technology is expanding the data capture opportunities. The UAV, as a close range remote sensing platform, can capture high resolution photography on-demand. This imagery can be used to produce dense point clouds using multi-view stereopsis techniques (MVS combining computer vision and photogrammetry. This study examines point clouds produced using MVS techniques applied to UAV and terrestrial photography. A multi-rotor micro UAV acquired aerial imagery from a altitude of approximately 30–40 m. The point clouds produced are extremely dense (<1–3 cm point spacing and provide a detailed record of the surface in the study area, a 70 m section of sheltered coastline in southeast Tasmania. Areas with little surface texture were not well captured, similarly, areas with complex geometry such as grass tussocks and woody scrub were not well mapped. The process fails to penetrate vegetation, but extracts very detailed terrain in unvegetated areas. Initially the point clouds are in an arbitrary coordinate system and need to be georeferenced. A Helmert transformation is applied based on matching ground control points (GCPs identified in the point clouds to GCPs surveying with differential GPS. These point clouds can be used, alongside laser scanning and more traditional techniques, to provide very detailed and precise representations of a range of landscapes at key moments. There are many potential applications for the UAV-MVS technique, including coastal erosion and accretion monitoring, mine surveying and other environmental monitoring applications. For the generated point clouds to be used in spatial applications they need to be converted to surface models that reduce dataset size without loosing too much detail. Triangulated meshes are one option, another is Poisson Surface Reconstruction. This latter option makes use of point normal

Coyotaje from the point of view of Central American migrant women

Directory of Open Access Journals (Sweden)

Simón Pedro Izcara Palacios

2017-01-01

Full Text Available This article, based on a qualitative methodology that includes in depth interviews with eighty Central American women who used migrant smugglers to reach the United States, examines her point of view about migrant smuggling. This paper concludes that one-sixth of respondents were deceived by migrant smugglers, and seven women suffered some form of sexual abuse from them, however more than two-thirds of the interviewees expressed a positive opinion towards migrant smugglers. This does not mean that women always trust migrant smugglers, they generally only trust those who were recommended for relatives or friends.

Persuasive Effects of Point of View, Protagonist Competence, and Similarity in a Health Narrative About Type 2 Diabetes.

Chen, Meng; Bell, Robert A; Taylor, Laramie D

2017-08-01

We examined the persuasive effects of three narrative features in a message about type 2 diabetes: narrative point of view (first- vs. third-person perspective), protagonist competence (positive role model who prevents diabetes vs. negative role model who develops diabetes), and protagonist-reader similarity (demographically similar vs. dissimilar). We posited that a first-person point of view would elevate people's identification levels more than a third-person point of view, especially when the protagonist was depicted as a positive role model. We also expected a similar protagonist to foster greater levels of identification than a dissimilar one. In addition, the positive effect of a competent role model on identification was expected to be enhanced under the condition of reader-protagonist similarity. Finally, we hypothesized that the effects of identification on persuasion would be mediated by self-referencing. Participants 30 years of age or younger (N = 489) were randomly assigned to read a story about a person with a family history of type 2 diabetes that was altered with regard to the experimental factors. Thereafter they completed a questionnaire incorporating measures of study variables. Greater levels of identification were found to foster self-referencing, leading to persuasion. Identification was strongest with a first-person point of view and when the narrator was a positive role model. The effect of identification on persuasion was mediated by self-referencing. Contrary to expectations, protagonist-reader demographic similarity did not affect identification or self-referencing. There was no support for the two moderation hypotheses.

Point-of-view writing: A method for increasing medical students' empathy, identification and expression of emotion, and insight.

Shapiro, Johanna; Rucker, Lloyd; Boker, John; Lie, Desiree

2006-03-01

Although interest exists among medical educators in using writing that reflects on clinical experience to enhance medical students' communication skills, empathy, and overall professionalism, little empirical research documents the value of this approach. This study explored whether students trained in one type of writing would first demonstrate increased awareness of emotional aspects of a clinical encounter in their writing; and second, be evaluated more positively in an OSCE situation by standardized patients. Ninety-two students were assigned to either a point-of-view writing or a clinical reasoning condition as part of a second year doctoring course. At the end of the year, students were evaluated in an OSCE format on 3 cases, and completed a writing assignment about an ER death from cardiac arrest. Student essays were scored according to presence or absence of various themes. A linguistic analysis of the essays was also performed. Point-of-view and clinical reasoning group scores were compared on both measures, as well as on the standardized patient OSCE ratings. Students trained in point-of-view writing demonstrated significantly more awareness of emotional and spiritual aspects of a paper case in a writing assignment than did students trained in clinical reasoning. By contrast, students in the clinical reasoning group were more likely to distance from the scenario. The two groups did not differ on SP OSCE ratings. Training in point-of-view writing can improve medical students' written skills on certain affective dimensions. It is not clear that these skills can translate into clinical behavior.

Revision of the Paris Convention from the German point of view

International Nuclear Information System (INIS)

Mahlmann, Wilfried.

1977-01-01

The paper discusses the revision of the Paris Convention from the German point of view and states how this country has used the possibilities for exceptions provided under the Convention so that German nuclear third party liability legislation differs somewhat from the standards laid down in the Convention. This is explained by a desire to provide increased financial security for the population concerned. After describing various proposed procedures for increasing liability amounts in the Paris Convention and the Brussels Supplementary Convention the author concludes that his country would welcome a revision of the Conventions which would provide increased financial security for the public.

A. Di Maio

2016-08-01

Channel Regional Model developed in the framework of PON-TESSA (Programma Operativo Nazionale; National Operative Program – TEchnology for the Situational Sea Awareness project. The main objective of the work is to validate a new approach of leeway calculation that relies on a real person in water (PIW event, which occurred in the Tyrrhenian Sea in July 2013. The results show that by assimilating a human body to a cylinder and estimating both the transition from laminar to turbulent boundary layer and the drag coefficients, it can be possible to solve a force balance equation, which allows the search area to be estimated with good approximation. This new point of view leads to the possibility of also testing the same approach for other different categories of targets, so as to overcome the limitations associated with the calculation of the leeway in the future by means of standard statistical law.

INSPIRE from the JRC Point of View

Full Text Available This paper summarises some recent developments in INSPIRE implementation from the JRC (Joint Research Centre point of view. The INSPIRE process started around 11 years ago and today, clear results and benefits can be seen. Spatial data are more accessible and shared more frequently between countries and at the European level. In addition to this, efficient, unified coordination and collaboration between different stakeholders and participants has been achieved, which is another great success. The JRC, as a scientific think-tank of the European Commission, has played a very important role in this process from the very beginning. This role is in line with its mission, which is to provide customer-driven scientific and technical support for the conception, development, implementation and monitoring of European Union (EU policies. The JRC acts as the overall technical coordinator of INSPIRE, but it also carries out the activities necessary to support the coherent implementation of INSPIRE, by helping member states in the implementation process. Experiences drawn from collaboration and negotiation in each country and at the European level will be of great importance in the revision of the INSPIRE Directive, which is envisaged for 2014.

Photoelectric effect from observer's mathematics point of view

Science.gov (United States)

Khots, Boris; Khots, Dmitriy

2014-12-01

When we consider and analyze physical events with the purpose of creating corresponding models we often assume that the mathematical apparatus used in modeling is infallible. In particular, this relates to the use of infinity in various aspects and the use of Newton's definition of a limit in analysis. We believe that is where the main problem lies in contemporary study of nature. This work considers Physical aspects in a setting of arithmetic, algebra, geometry, analysis, topology provided by Observer's Mathematics (see www.mathrelativity.com). Certain results and communications pertaining to solution of these problems are provided. In particular, we prove the following Theorems, which give Observer's Mathematics point of view on Einstein photoelectric effect theory and Lamb-Scully and Hanbury-Brown-Twiss experiments: Theorem 1. There are some values of light intensity where anticorrelation parameter A ∈ [0,1). Theorem 2. There are some values of light intensity where anticorrelation parameter A = 1. Theorem 3. There are some values of light intensity where anticorrelation parameter A > 1.

2015-09-01

When we create mathematical models for quantum theory of light we assume that the mathematical apparatus used in modeling, at least the simplest mathematical apparatus, is infallible. In particular, this relates to the use of "infinitely small" and "infinitely large" quantities in arithmetic and the use of Newton - Cauchy definitions of a limit and derivative in analysis. We believe that is where the main problem lies in contemporary study of nature. We have introduced a new concept of Observer's Mathematics (see www.mathrelativity.com). Observer's Mathematics creates new arithmetic, algebra, geometry, topology, analysis and logic which do not contain the concept of continuum, but locally coincide with the standard fields. We use Einstein special relativity principles and get the analogue of classical Lorentz transformation. This work considers this transformation from Observer's Mathematics point of view.

Full Text Available As in many developing countries, the service sector in Brazil is responsible for generating income and employment for a significant portion of the population. Due to this economic relevance, service organizations are faced with an increasingly demanding and competitive market. This demand greater innovation and business planning. Despite this, the process of service development remains a relatively unexplored subject in the literature. Several issues regarding the planning and management remain without clear ideas or propositions that guide their appropriate treatment. The result of this situation, the methods and techniques that help design the services are not properly disseminated. These are scattered through the literature of operations management services. Given this framework, the light of a review of the literature and concerning the elements that compose the service project according to the works of Machuca, Zamora-Gonzalez and Aguilar-Escobar (2007 and Edvardsson (1997, the present work points and examine the methods and techniques suggested by many authors and works on the area of Service Operations. It was found that the knowledge about the methods and techniques is diffuse. This knowledge is concentrated on the design process and determining the location of services.

Frost, Darrel R.; McDiarmid, Roy W.; Mendelson, Joseph R.

2009-01-01

The Point of View by Gregory Pauly, David Hillis, and David Cannatella misrepresents the motives and activities of the anuran subcommittee of the Scientific and Standard English Names Committee, contains a number of misleading statements, omits evidence and references to critical literature that have already rejected or superseded their positions, and cloaks the limitations of their nomenclatural approach in ambiguous language. Their Point of View is not about promoting transparency in the process of constructing the English Names list, assuring that its taxonomy is adequately reviewed, or promoting nomenclatural stability in any global sense. Rather, their Point of View focuses in large part on a single publication, The Amphibian Tree of Life, which is formally unrelated to the Standard English Names List, and promotes an approach to nomenclature mistakenly asserted by them to be compatible with both the International Code of Zoological Nomenclature and one of its competitors, the PhyloCode.

Solar based cells coated by nanoparticles (NPs) acknowledge potential utilizing as a part of photovoltaic innovation. The acquired silicon solar cells (Si-SCs) coated with different sizes of silver nanoparticles (Ag NPs) as well as uncoated were fabricated in our lab. The sizes and optical properties of prepared NPs were characterized by spectroscopic techniques and Mie theory respectively. The reflectivity of Si-SCs showed reduction of this property as the size of NPs increased. Electrical properties as open circuit current, fill factor and output power density were assessed and discussed depending on point of view of Mie theory for the optical properties of NPs. Also, photostabilities of SCs were assessed using diode laser of wavelength 450 nm and power 300 mW. Coated SCs with the largest Ag NPs size showed the highest Photostability due to its highest scattering efficiency according to Mie theory concept.

2012-05-01

Full Text Available Sensor miniaturisation, improved battery technology and the availability of low-cost yet advanced Unmanned Aerial Vehicles (UAV have provided new opportunities for environmental remote sensing. The UAV provides a platform for close-range aerial photography. Detailed imagery captured from micro-UAV can produce dense point clouds using multi-view stereopsis (MVS techniques combining photogrammetry and computer vision. This study applies MVS techniques to imagery acquired from a multi-rotor micro-UAV of a natural coastal site in southeastern Tasmania, Australia. A very dense point cloud ( < 1–3 cm point spacing is produced in an arbitrary coordinate system using full resolution imagery, whereas other studies usually downsample the original imagery. The point cloud is sparse in areas of complex vegetation and where surfaces have a homogeneous texture. Ground control points collected with Differential Global Positioning System (DGPS are identified and used for georeferencing via a Helmert transformation. This study compared georeferenced point clouds to a Total Station survey in order to assess and quantify their geometric accuracy. The results indicate that a georeferenced point cloud accurate to 25–40 mm can be obtained from imagery acquired from 50 m. UAV-based image capture provides the spatial and temporal resolution required to map and monitor natural landscapes. This paper assesses the accuracy of the generated point clouds based on field survey points. Based on our key findings we conclude that sub-decimetre terrain change (in this case coastal erosion can be monitored.

KAERI and KEPCO consortium had performed standard design of SMART(System integrated Modular Advanced ReacTor) from 2009 to 2011 and obtained standard design approval in July 2012. To confirm the safety of SMART design, all of the safety related design basis events were analyzed. A feedwater line break (FLB) is a postulated accident and is a limiting accident for a decrease in the heat removal by the secondary system in the view point of the peak RCS pressure. It is well known that departure from nucleate boiling ratio (DNBR) increases with the increase of the system pressure for conventional nuclear power plants. But SMART has comparatively lower RCS flow rate, and there is a possibility to show different DNBR behavior depending on the system pressure. To confirm that SMART is safe in case of FLB accident, the Korean nuclear regulatory body required to perform the safety analysis in the view point of minimum DNBR (MDNBR) during the licensing review process for standard design approval (SDA) of SMART design.

[Health protection from an ethical point of view].

Kreb, Hartmut

2008-08-01

Illness and health are terms open to interpretation. Their meaning depends on cultural backgrounds, societal designations and historical change. During the modern era, having been shaped by natural sciences, knowledge in medicine has grown exponentially. However, critical voices warn of a medicalization of the image of humanity or an "absolutization" of health. They emphasize that limits must be set to medical progress. In return it has to be highlighted that contemporary medicine has opened up new chances of therapy, prevention and palliative treatment (pain relief), which could not be applied previously. As a result, it is the responsibility of medicine to make available the highest possible measure of progress to patients. The medical profession is confronted with the task of supporting patients in their right to self-determination and their decision competence. For the individual human being, health is a fundamental good. Therefore, each human individual has the right to health protection and medical care which correspond to the latest medical knowledge available. By now, this right has been acknowledged by human rights conventions and numerous legal documents. From an ethical point of view, health protection has to be interpreted as 1) the right to defense, 2) the right to claim and 3) the patient's right to participate. It falls to medical ethics to substantiate the meaning of health protection for the different spheres of medical activity.

Whole object surface area and volume of partial-view 3D models

International Nuclear Information System (INIS)

Mulukutla, Gopal K; Proussevitch, Alexander A; Genareau, Kimberly D; Durant, Adam J

2017-01-01

Micro-scale 3D models, important components of many studies in science and engineering, are often used to determine morphological characteristics such as shape, surface area and volume. The application of techniques such as stereoscopic scanning electron microscopy on whole objects often results in ‘partial-view’ models with a portion of object not within the field of view thus not captured in the 3D model. The nature and extent of the surface not captured is dependent on the complex interaction of imaging system attributes (e.g. working distance, viewing angle) with object size, shape and morphology. As a result, any simplistic assumptions in estimating whole object surface area or volume can lead to significant errors. In this study, we report on a novel technique to estimate the physical fraction of an object captured in a partial-view 3D model of an otherwise whole object. This allows a more accurate estimate of surface area and volume. Using 3D models, we demonstrate the robustness of this method and the accuracy of surface area and volume estimates relative to true values. (paper)

Full Text Available Considering the influence of literature on people lives, this study investigates elements concerning views about scientists and scientific work presented in Deception Point, a novel by Dan Brown. Multiple aspects to represent the scientist figure, life and work, emerge from the novel and problematize characteristics that can be considered as a common sense view, or others perspectives based on more contemporaneous philosophical thoughts on science. Reading and analyzing this novel could be an interesting opportunity to insert elements of history and philosophy of science under different focus. This study discusses some elements, from excerpts of the novel, which may become possibilities for debates in Science classes at schools, and in teacher education.

Adapting university programmes to European Higher Education Area criteria has required substantial changes in curricula and teaching methodologies. Reflective learning (RL) has attracted growing interest and occupies an important place in the scientific literature on theoretical and methodological aspects of university instruction. However, fewer studies have focused on evaluating the RL methodology from the point of view of nursing students. To assess nursing students' perceptions of the usefulness and challenges of RL methodology. Mixed method design, using a cross-sectional questionnaire and focus group discussion. The research was conducted via self-reported reflective learning questionnaire complemented by focus group discussion. Students provided a positive overall evaluation of RL, highlighting the method's capacity to help them better understand themselves, engage in self-reflection about the learning process, optimize their strengths and discover additional training needs, along with searching for continuous improvement. Nonetheless, RL does not help them as much to plan their learning or identify areas of weakness or needed improvement in knowledge, skills and attitudes. Among the difficulties or challenges, students reported low motivation and lack of familiarity with this type of learning, along with concerns about the privacy of their reflective journals and about the grading criteria. In general, students evaluated RL positively. The results suggest areas of needed improvement related to unfamiliarity with the methodology, ethical aspects of developing a reflective journal and the need for clear evaluation criteria.

Implications of Harvest on the Boundaries of Protected Areas for Large Carnivore Viewing Opportunities.

Directory of Open Access Journals (Sweden)

Bridget L Borg

Full Text Available The desire to see free ranging large carnivores in their natural habitat is a driver of tourism in protected areas around the globe. However, large carnivores are wide-ranging and subject to human-caused mortality outside protected area boundaries. The impact of harvest (trapping or hunting on wildlife viewing opportunities has been the subject of intense debate and speculation, but quantitative analyses have been lacking. We examined the effect of legal harvest of wolves (Canis lupus along the boundaries of two North American National Parks, Denali (DNPP and Yellowstone (YNP, on wolf viewing opportunities within the parks during peak tourist season. We used data on wolf sightings, pack sizes, den site locations, and harvest adjacent to DNPP from 1997-2013 and YNP from 2008-2013 to evaluate the relationship between harvest and wolf viewing opportunities. Although sightings were largely driven by wolf population size and proximity of den sites to roads, sightings in both parks were significantly reduced by harvest. Sightings in YNP increased by 45% following years with no harvest of a wolf from a pack, and sightings in DNPP were more than twice as likely during a period with a harvest buffer zone than in years without the buffer. These findings show that harvest of wolves adjacent to protected areas can reduce sightings within those areas despite minimal impacts on the size of protected wolf populations. Consumptive use of carnivores adjacent to protected areas may therefore reduce their potential for non-consumptive use, and these tradeoffs should be considered when developing regional wildlife management policies.

Points of View: Herbert Bayer’s Exhibition Catalogue for the 1930 Section Allemande

Directory of Open Access Journals (Sweden)

Wallis Miller

2017-01-01

Full Text Available Sigfried Giedion called Herbert Bayer’s exhibition catalogue for the 1930 'Section Allemande' a “minor typographical masterpiece.” Like similar catalogues, it is inexpensive, provides an inventory list, has an introduction, functions as a guide, and is illustrated. However, the majority of its images are of installations, not their contents. Bayer accommodates the catalogue type for applied arts exhibitions by listing installations as objects, but he confronts the type by showing installations as display contexts that establish points of view, emulating, idealizing and interpreting the experience of the exhibition. By independently constructing ways of seeing and understanding the exhibition, the catalogue resists being an appendage to the exhibition, despite their close relationship. Giedion may have viewed Bayer’s catalogue as an important but secondary work of graphic design, but this article argues that it is of primary significance as an exhibition catalogue, an unusual essay on the book typology that is conscious of its history while moving outside — to other types of book design and to exhibitions — to transform it.

Spectral analysis of growing graphs a quantum probability point of view

CERN Document Server

Obata, Nobuaki

2017-01-01

This book is designed as a concise introduction to the recent achievements on spectral analysis of graphs or networks from the point of view of quantum (or non-commutative) probability theory. The main topics are spectral distributions of the adjacency matrices of finite or infinite graphs and their limit distributions for growing graphs. The main vehicle is quantum probability, an algebraic extension of the traditional probability theory, which provides a new framework for the analysis of adjacency matrices revealing their non-commutative nature. For example, the method of quantum decomposition makes it possible to study spectral distributions by means of interacting Fock spaces or equivalently by orthogonal polynomials. Various concepts of independence in quantum probability and corresponding central limit theorems are used for the asymptotic study of spectral distributions for product graphs. This book is written for researchers, teachers, and students interested in graph spectra, their (asymptotic) spectr...

FIFTY YEARS OF YANG-MILLS THEORIES: A Phenomenological Point of View

Science.gov (United States)

de Rújula, Alvaro

On the occasion of the celebration of the first half-century of Yang-Mills theories, I am contributing a personal recollection of how the subject, in its early times, confronted physical reality, that is, its "phenomenology". There is nothing original in this work, except, perhaps, my own points of view. But I hope that the older practitioners of the field will find here grounds form nostalgia, or good reasons to disagree with me. Younger addicts may learn that history does not resemble at all what is reflected in current textbooks: it was orders of magnitude more fascinating.

On the occasion of the celebration of the first half-century of Yang--Mills theories, I am contributing a personal recollection of how the subject, in its early times, confronted physical reality, that is, its "phenomenology". There is nothing original in this work, except, perhaps, my own points of view. But I hope that the older practitioners of the field will find here grounds for nostalgia, or good reasons to disagree with me. Younger addicts may learn that history does not resemble at all what is reflected in current textbooks: it was orders of magnitude more fascinating.

The SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY (SCIAMACHY) on Envisat (2002-2012) performed nadir, limb, solar/lunar occultation and various monitoring measurements. The pointing information of the instrument is determined by the attitude information of the Envisat platform with its star trackers together with the encoder readouts of both the azimuth and the elevation scanner of SCIAMACHY. In this work, we present additional sources of attitude information from the SCIAMACHY measurements itself. The basic principle is the same as used by the star tracker: we measure the viewing direction towards celestial objects, i.e. sun and moon, to detect possible mispointings. In sun over limb port observations, we utilise the vertical scans over the solar disk. In horizontal direction, SCIAMACHY's sun follower device (SFD) is used to adjust the viewing direction. Moon over limb port measurements use for both the vertical and the horizontal direction the adjustment by the SFD. The viewing direction is steered towards the intensity centroid of the illuminated part of the lunar disk. We use reference images from the USGS Robotic Lunar Observatory (ROLO) to take into account the inhomogeneous surface and the variations by lunar libration and phase to parameterise the location of the intensity centroid from the observation geometry. Solar observations through SCIAMACHY's so-called sub-solar port (with a viewing direction closely to zenith) also use the SFD in the vertical direction. In the horizontal direction the geometry of the port defines the viewing direction. Using these three type of measurements, we fit improved mispointing parameters by minimising the pointing offsets in elevation and azimuth. The geolocation of all retrieved products will benefit from this; the tangent heights are especially improved. The altitudes assigned to SCIAMACHY's solar occultation measurements are changed in the range of -130 to -330 m, the lunar occultation

Enhancing multi-view autostereoscopic displays by viewing distance control (VDC)

Conventional multi-view displays spatially interlace various views of a 3D scene and form appropriate viewing channels. However, they only support sufficient stereo quality within a limited range around the nominal viewing distance (NVD). If this distance is maintained, two slightly divergent views are projected to the person's eyes, both covering the entire screen. With increasing deviations from the NVD the stereo image quality decreases. As a major drawback in usability, the manufacturer so far assigns this distance. We propose a software-based solution that corrects false view assignments depending on the distance of the viewer. Our novel approach enables continuous view adaptation based on the calculation of intermediate views and a column-bycolumn rendering method. The algorithm controls each individual subpixel and generates a new interleaving pattern from selected views. In addition, we use color-coded test content to verify its efficacy. This novel technology helps shifting the physically determined NVD to a user-defined distance thereby supporting stereopsis. The recent viewing positions can fall in front or behind the NVD of the original setup. Our algorithm can be applied to all multi-view autostereoscopic displays — independent of the ascent or the periodicity of the optical element. In general, the viewing distance can be corrected with a factor of more than 2.5. By creating a continuous viewing area the visualized 3D content is suitable even for persons with largely divergent intraocular distance — adults and children alike — without any deficiency in spatial perception.

The balance of protein expression and degradation: an ESCRTs point of view.

Science.gov (United States)

Babst, Markus; Odorizzi, Greg

2013-08-01

Endosomal sorting complexes required for transport (ESCRTs) execute the biogenesis of late endosomal multivesicular bodies (MVBs). The ESCRT pathway has traditionally been viewed as a means by which transmembrane proteins are degraded in vacuoles/lysosomes. More recent studies aimed at understanding the broader functions of ESCRTs have uncovered unexpected links with pathways that control cellular metabolism. Central to this communication is TORC1, the kinase complex that controls many of the catabolic and anabolic systems. The connection between TORC1 activity and ESCRTs allows cells to quickly adapt to the stress of nutrient limitations until the longer-term autophagic pathway is activated. Increasing evidence also points to ESCRTs regulating RNA interference (RNAi) pathways that control translation. Copyright © 2013 Elsevier Ltd. All rights reserved.

Full Text Available Purpose of the article: The article examines preffered structure of competences from Russian employers’s point of view in order to provide universities with the knowledge on how graduates’ skills are viewed by the main customers. Methodology/methods: The article is based on factor analysis of competences which are derived from the questionnaire which was distributed to Russian enterprises (mainly meduim sized manufacturing enterprises. The questionnaires were gathered from management of the companies, and evaluated by factor analysis using varimax method. Significance of the findings is confirmed by the level of Cronbach alpha. Scientific aim: The scientific aim of the article is to define the main competences of university graduates as they are seen by employers. The paper also aims to define whether the structure of preffered competences differs alone the timeline, i.e. do employers evaluate their requirements in past, present and future differently. Findings: In the article it is revealed that preferred structure of competences university graduates should possess evolves overtime, and that employers have lower understanding of their needs and requirments for the future. Second, it appeared that the most signigicant graduates’ competences are systemic thinking and professional skills, but the other factors may only be considered moderator of these skills in future. Finally, multidisciplinary skills appear to gain significance along the timeline of the study, so employers are looking for multidisciplinary skills for the future as a response for existing high turbulence. Conclusions: The main limitations of the study are small sample and focus on mid-Russian meduim enterprises, which are mainly manufacturing. The study has distinct applications to practice by defining the most significant graduates’ competences from employers’ perspective, and to theory by proposing evolution paths for competence significance.

2017-01-01

To try to establish a "point by point" relationship between the local thickness of the retinal ganglion cell complex and its sensitivity. In total, 104 glaucomatous eyes of 89 patients with a confirmed 24-2 visual field, were measured by superimposing the visual field, using imaging software, with the Wide 40° by 30° measurements of retinal ganglion cell complex obtained from the Topcon © 3D 2000 OCT, after upward adjustment, inversion and scaling. Visual fields were classified into two groups according to the extent of the disease: 58 mild to moderate (MD up to -12dB), and 46 severe (MD beyond -12dB). The 6mm by 6mm central region, equipped with a normative database, was studied, corresponding to 16 points in the visual field. These points were individually matched one by one to the local ganglion cell complex, which was classified into 2 groups depending on whether it was greater or less than 70 microns. The normative database confirmed the pathological nature of the thin areas, with a significance of 95 to 99%. Displacement of central retinal ganglion cells was compensated for. Of 1664 points (16 central points for 104 eyes), 283 points were found to be "borderline" and excluded. Of the 1381 analyzed points, 727 points were classified as "over 70 microns" and 654 points "under 70 microns". (1) For all stages combined, 85.8% of the 727 points which were greater than 70 microns had a deviation between -3 and +3dB: areas above 70 microns had no observable loss of light sensitivity. (2) In total, 92.5% of the 428 points having a gap ranging from -6 to -35dB were located on ganglion cell complex areas below 70 microns: functional visual loss was identified in thin areas, which were less than 70 microns. (3) Areas which were less than 70 microns, that is 654 points, had quite variable sensitivity and can be divided into three groups: the first with preserved sensitivity, another with obliterated sensitivity, and an intermediate group connecting

High-Precision Registration of Point Clouds Based on Sphere Feature Constraints

Directory of Open Access Journals (Sweden)

Junhui Huang

2016-12-01

Full Text Available Point cloud registration is a key process in multi-view 3D measurements. Its precision affects the measurement precision directly. However, in the case of the point clouds with non-overlapping areas or curvature invariant surface, it is difficult to achieve a high precision. A high precision registration method based on sphere feature constraint is presented to overcome the difficulty in the paper. Some known sphere features with constraints are used to construct virtual overlapping areas. The virtual overlapping areas provide more accurate corresponding point pairs and reduce the influence of noise. Then the transformation parameters between the registered point clouds are solved by an optimization method with weight function. In that case, the impact of large noise in point clouds can be reduced and a high precision registration is achieved. Simulation and experiments validate the proposed method.

Suicide from a Holistic Point of View

Directory of Open Access Journals (Sweden)

Søren Ventegodt

2005-01-01

Full Text Available Suicide has been honoured and respected in the eastern culture, especially in Japan with the famous tradition of Hara-kiri, or seppuku, while in most western societies suicide has been seen negatively and many contemporary physicians tend to consider suicide the most self-destructive and evil thing a human being can do and something that should be avoided at all cost. Religions also have different viewpoints on suicide, but from a philosophical point of view we believe that considering the choice of life and dead to be extremely relevant for a good living. The choice of life and dead is real, since responsibility for life is necessary in order to live life and even the best physician cannot keep a patient alive, who deep inside wants to die. In this chapter, we present parts of a story of a young girl who had experienced child sexual abuse. In holistic existential therapy, it is our experience, when the patient is well supported in the confrontation of the fundamental questions related to assuming responsibility for the coherence, that this confrontation will almost always lead to a big YES to life. Without confronting the fundamental question of “to be or not to be”, life can never be chosen 100% and thus never be lived fully.

Brain aging and neurodegeneration: from a mitochondrial point of view.

Science.gov (United States)

Grimm, Amandine; Eckert, Anne

2017-11-01

Aging is defined as a progressive time-related accumulation of changes responsible for or at least involved in the increased susceptibility to disease and death. The brain seems to be particularly sensitive to the aging process since the appearance of neurodegenerative diseases, including Alzheimer's disease, is exponential with the increasing age. Mitochondria were placed at the center of the 'free-radical theory of aging', because these paramount organelles are not only the main producers of energy in the cells, but also to main source of reactive oxygen species. Thus, in this review, we aim to look at brain aging processes from a mitochondrial point of view by asking: (i) What happens to brain mitochondrial bioenergetics and dynamics during aging? (ii) Why is the brain so sensitive to the age-related mitochondrial impairments? (iii) Is there a sex difference in the age-induced mitochondrial dysfunction? Understanding mitochondrial physiology in the context of brain aging may help identify therapeutic targets against neurodegeneration.

Defining Issue According to the statistics presented by the Ministry of Emergencies of Ukraine, river floods have imposed the most severe damages to the sectors of economy and the human communities in Ukraine. But, an adaptability and a vulnerability of Ukrainian society to floods are still poorly understood. Results Presentation In the response to increasing flood losses in the country between 1998 and 2008, the State Hydrometeorological Service of Ukraine, which is subordinate to the Ministry of Emergencies, in the cooperation with the National Academy of Sciences of Ukraine have carried out the research study focusing on public views on the problem of river floods for Ukraine. Aims of this study were: a) exploring the main sources of information on water-related hazards and the level of knowledge useful in a flood crisis situation in different groups of peoples; b) learning what the various population groups think of the most significant causes and consequences of flood damages and the role of various central/governmental/ and local authorities in an elaboration and implementation of mitigation measures. Public attitudes towards various prevention and mitigation strategies, as well as sources of emerging conflict were also revealed. The results of study have given a possibility to compare points of view of population groups which: a) living in the low- and high- flood risk areas; b) living in the urban and rural areas; c) having the different levels of education. The responses from 2550 residents have been analyzed and summarized. Among the most important findings of this study can be indicated following: a) on the one hand, the level of knowledge of some aspects of flood problem (impact of climate variation and change, adaptation measures) of the general public should be improved, on the other hand, the most of peoples understand that floods are the significant economical and ecological problem; b) views of the public on the problem differ very much with regard

[Regulation of sexual expression in residential aged care facilities: A professional point of view].

Villar, Feliciano; Fabà, Josep; Celdrán, Montserrat; Serrat, Rodrigo

2014-01-01

The purpose of this study is to determine the opinion of professionals working in residential aged care facilities on the regulation of sexuality in these settings. Fifty-three professionals from five residential aged care facilities located in the metropolitan area of Barcelona answered several questions regarding the advisability of establishing measures for the regulation of sexuality in RACFs, the elements that could contribute to this, and the aspects that such regulations should consider. Around 50% of the participants recognized the advisability of having some type of measures for sexuality regulation in residential aged care facilities. According to their responses this should be developed taking into account professional opinions, but also the points of view of the residents and their relatives. The most frequently mentioned regulations were those that ensured that any kind of sexually charged situation occurred in a private environment. The development of strategies are suggested to distinguish those people with dementia that are competent to consent to sexual acts from those who are not. The opinion of professionals working in RACFs regarding the advisability of establishing measures for sexuality regulation seems to be considerably divided. Thus, whilst around 50% of them recognize their potential usefulness, the other half consider them unnecessary or even counterproductive for the sexual freedom of residents. Associating regulation with prohibition and sexuality with sexual activity was not uncommon among the responses of the participants. Copyright © 2014 SEGG. Published by Elsevier Espana.

Combined radio- and chemotherapy from the point of view of the internist-oncologist

International Nuclear Information System (INIS)

Engelhardt, R.

1979-01-01

The indications for a combined radio- and chemotherapy can be summarized from three points of view: 1) Intensifying local radiotherapy by chemotherapy. 2) Extending local radiotherapy by systematical chemotherapy. 3) Supporting chemotherapy by radiotherapy. The side effects of the combination are discussed, classified as immediate type and long-term type. It is indicated that in all combinations the drug-specific and/or organ-specific side effects of the cytostatics must be taken into consideration. The substantial therapeutical aspect lies in prophylaxis. Exact data concerning the reduction of the dosage of the radiotherapy and/or the chemotherapy must be found after exact observation of the complications. Knowing the side effects of the immediate-type and taking into consideration the long-term damage which can be expected, there are today clear indications for a combined radio- and chemotherapy.

2009-01-01

This document gives an overview of the opinion of the FNE (France Nature Environnement), a French association involved in the protection of the environment, about the idea of developing technologies enabling the capturing and sequestrating of carbon dioxide. It outlines that industries are considering such technologies as the adequate solution as they would allow a development of activities while limiting greenhouse gas releases. But the FNE has an opposite point of view; advantages and limitations of this technology are thus discussed (reduction of greenhouse gas emissions but with an increase of energy consumption, industrial hazards, mobilization of large financial resources). The principles under which such technologies could be used and financed in some specific situations and under precise conditions are then discussed. Notably, it stresses the importance of a limitation of public financing, of participation and communication, of judicial guarantees

Two psychiatrists and their points of view imagery in psychiatry: fact and reverie

For the point of view of the psychiatrist, new tools of cerebral imagery (NMR imaging, positron computed tomography, single photon emission computed tomography) represents a considerable interest. But the interpretation of the results is still insufficient. The scientific literature is full of articles with questionable or difficult interpretation conclusions. At the present time, an image does not allow to give a diagnosis nor to follow the history of a syndrome. But it will probably come in the future. (O.M.)

Since the development of microcolumn system, it attracted much attention because multiple microcolumns can be assembled into arrayed form, which is expected to generate multiple electron beams and overcome the disadvantage of electron beam inspection equipments, low throughput . However, it is not easy to apply a microcolumn to the practical inspection or testing equipment since its scanning area is too small. Even if the arrayed operation using multiple microcolumns can overcome this limit, it requires complicated supporting systems and related technologies to operate a number of microcolumns simultaneously. Therefore, we tried to modify microcolumn design itself so that it can have a large field of view. In this work, two kinds of modified columns will be suggested and the preliminary results showing their performance of scanning large area will be discussed. -- Highlights: Black-Right-Pointing-Pointer Two types of microcolumn designs to achieve a large field of view are fabricated. Black-Right-Pointing-Pointer Field of view of a microcolumn increases linearly with the working distance. Black-Right-Pointing-Pointer New designed microcolumns can be developed as a low energy column system for large view inspections.

On the theory of drainage area for regular and non-regular points

Science.gov (United States)

Bonetti, S.; Bragg, A. D.; Porporato, A.

2018-03-01

The drainage area is an important, non-local property of a landscape, which controls surface and subsurface hydrological fluxes. Its role in numerous ecohydrological and geomorphological applications has given rise to several numerical methods for its computation. However, its theoretical analysis has lagged behind. Only recently, an analytical definition for the specific catchment area was proposed (Gallant & Hutchinson. 2011 Water Resour. Res. 47, W05535. (doi:10.1029/2009WR008540)), with the derivation of a differential equation whose validity is limited to regular points of the watershed. Here, we show that such a differential equation can be derived from a continuity equation (Chen et al. 2014 Geomorphology 219, 68-86. (doi:10.1016/j.geomorph.2014.04.037)) and extend the theory to critical and singular points both by applying Gauss's theorem and by means of a dynamical systems approach to define basins of attraction of local surface minima. Simple analytical examples as well as applications to more complex topographic surfaces are examined. The theoretical description of topographic features and properties, such as the drainage area, channel lines and watershed divides, can be broadly adopted to develop and test the numerical algorithms currently used in digital terrain analysis for the computation of the drainage area, as well as for the theoretical analysis of landscape evolution and stability.

Use of ground based remote sensing technologies such as scanning lidar systems (light detection and ranging) has gained traction in characterizing ambient aerosols due to some key advantages such as wide area of regard (10 km2), fast response time, high spatial resolution (University, in conjunction with the USDA-ARS, has developed a three-wavelength scanning lidar system called Aglite that has been successfully deployed to characterize particle motion, concentration, and size distribution at both point and diffuse area sources in agricultural and industrial settings. A suite of massbased and size distribution point sensors are used to locally calibrate the lidar. Generating meaningful particle size distribution, mass concentration, and emission rate results based on lidar data is dependent on strategic onsite deployment of these point sensors with successful local meteorological measurements. Deployment strategies learned from field use of this entire measurement system over five years include the characterization of local meteorology and its predictability prior to deployment, the placement of point sensors to prevent contamination and overloading, the positioning of the lidar and beam plane to avoid hard target interferences, and the usefulness of photographic and written observational data.

The definition of ashi point has not been unified yet till now. Likewise, the precise explanation on its connotation has always been an elusive question in acupuncture theory. By collecting diverse definitions on ashi point in the textbooks of Acupuncture and Moxibustion , dictionaries and term standards, several rational elements in definitions with consensus were screened. With the assistance of two important theories of cognitive linguistics, such as figure-ground theory and distance iconicity theory, the concept of ashi point was newly defined. Additiona-lly, on the base of the understanding on several similar terms such as "taking the painful site as acupoint", "responding point" and "reactive point", the semanteme analytic method was used to distinguish the difference among them so that the more profound explorations on acupuncture therapy are expounded.

In order to achieve the goals of social commentary and moral judgement pursued in her novels, Jane Austen describes and evaluates different aspects of her characters’ personalities: social attitude, intellectual qualities and moral traits (Lodge 1966). Mansfield Park (1814) is one of her novels in which this moral awareness is most acute. In order to construct a community of shared values with her readers, Austen skilfully alternates different points of view as sources of evaluation. We propo...

The study aimed at investigating the nurses' administration points of view concerning managing activities in the hospital macro-system, based on the Administration Contingent Theory A group of 9 nurses responsible for the administration of nursing services at 6 reference hospitals in Fortaleza/Ceara, participated of the study. Data were assessed by means of free interview techniques, from August to December 2001. The results suggest that the administrative approach focused the development of Leadership and Control activities. The interview outcomes reveal that nursing administration in a Hospital Macro-system was not perceived as an easy task, but feasible nevertheless. The greatest difficulty seemed to be due to a poor reflexive practice about the nurse's administrative attributions.

Is it possible to establish (at short, medium and long term) future work conditions or expected work conditions for Colombian people considering upcoming work technologies? Is it possible to anticipate future work desirable work conditions for Colombian people in order to plan (foresee?) work technologies? These questions guided this research and they point to an action thesis and to a reaction one in this context of work crisis. Even though a work technology establishes where, when, how, who, who with, and using what element work is done, it also establishes certain work conditions. Besides, multiple forms of considering and deconstructing past have been created from many disciplines. However, in order to foresee or construct work technologies requires a different perspective for looking further. This research has been carried out considering other disciplines points of view regarding Future Studies and Future Thinking Studies. This research has the purpose of finding future paths for Future Thinking Studies from ergonomics point of view in this moment of global work crisis we are going through.

2012-05-01

To systematically assess the physicians' point of view of multimedia support in preoperative patient education for radical prostatectomy. We evaluated the view of physicians performing multimedia supported preoperative educations within a randomized controlled trial. Therein 8 physicians educated 203 patients for radical prostatectomy. All physicians rated multimedia supported education better than the standard procedure. Main reasons were better comprehensibility, the visual presentation, and greater ease in explaining complex issues. Objective time measurement showed no difference between both educations. The major disadvantage was the impression, that multimedia supported education lasted longer. Moreover, they had the impression that some details could be further improved. Given the choice, every physician would decide for multimedia support. Physicians appreciate multimedia support in preoperative education and contrary to their impression, multimedia support does not prolong patient education. Therefore, patients and physicians likewise profit from multimedia support for education and counseling. The readiness of physicians is a possible obstacle to this improvement, as their view is a key factor for the transition to everyday routine. Therefore, our results could alleviate this possible barrier for establishing multimedia supported education in clinical routine. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Objective: To explore the right ventricular (RV) Tei index in patients with pulmonary hypertension (PH) by tissue Doppler imaging (TDI), and to explore more accurate observation point to obtain Tei index of right ventricular. Methods: Assessment of RV Tei index values was performed in 95 patients with PH and 32 normal subjects. The 95 patients were grouped into 3 groups according to the severity of PH. Tei index values were obtained by TDI measurement from three observation points, the anterior tricuspid and septal tricuspid attachment points in the apical 4-chamber view and the posterior tricuspid attachment point in parasternal right heart 2-chamber review. Results: (1) RV Tel index values were measured at the three points of PH was higher than the normal significantly (P<0.05). (2) RV Tei index values of the three PH groups at he anterior tricuspid attachment had significant difference each other (P<0.05). RV Tei index values of low-grade and medium-grade PH groups at septal tricuspid and posterior tricuspid had no significant difference, but that of high-grade PH group were higher than the low-grade and medium-grade PH group. Conclusion: RV Tei index value was significantly increased in PH patients. The Tei index value measured by TDI at anterior tricuspid attachment point in apical 4-chamber view was better than that at septal tricuspid attachment point in the apical 4-chamber view and posterior' attachment of parasternal right heart 2-chamber.

A real Young's double-slit experiment which can, without destroying the fringe pattern, establish unequivocally whether a photon passes like a wave along both the paths or passes like a particle along one or the other path only, is presented. The main feature of this experiment is that the point at which the incident wave is to be regarded as being split into two parts to go along the two paths is distinct from the point at which successive incident particles are to be regarded as having random choice to go along one or the other path. Our experimental results support Einstein's Einweg (one-path) point of view.

2013-05-01

With an advent of autostereoscopic display technique and increased needs for smart phones, there has been a significant growth in mobile TV markets. The rapid growth in technical, economical, and social aspects has encouraged 3D TV manufacturers to apply 3D rendering technology to mobile devices so that people have more opportunities to come into contact with many 3D content anytime and anywhere. Even if the mobile 3D technology leads to the current market growth, there is an important thing to consider for consistent development and growth in the display market. To put it briefly, human factors linked to mobile 3D viewing should be taken into consideration before developing mobile 3D technology. Many studies have investigated whether mobile 3D viewing causes undesirable biomedical effects such as motion sickness and visual fatigue, but few have examined main factors adversely affecting human health. Viewing distance is considered one of the main factors to establish optimized viewing environments from a viewer's point of view. Thus, in an effort to determine human-friendly viewing environments, this study aims to investigate the effect of viewing distance on human visual system when exposing to mobile 3D environments. Recording and analyzing brainwaves before and after watching mobile 3D content, we explore how viewing distance affects viewing experience from physiological and psychological perspectives. Results obtained in this study are expected to provide viewing guidelines for viewers, help ensure viewers against undesirable 3D effects, and lead to make gradual progress towards a human-friendly mobile 3D viewing.

Strategies for satellite-based monitoring of CO2 from distributed area and point sources

Schwandner, Florian M.; Miller, Charles E.; Duren, Riley M.; Natraj, Vijay; Eldering, Annmarie; Gunson, Michael R.; Crisp, David

Atmospheric CO2 budgets are controlled by the strengths, as well as the spatial and temporal variabilities of CO2 sources and sinks. Natural CO2 sources and sinks are dominated by the vast areas of the oceans and the terrestrial biosphere. In contrast, anthropogenic and geogenic CO2 sources are dominated by distributed area and point sources, which may constitute as much as 70% of anthropogenic (e.g., Duren & Miller, 2012), and over 80% of geogenic emissions (Burton et al., 2013). Comprehensive assessments of CO2 budgets necessitate robust and highly accurate satellite remote sensing strategies that address the competing and often conflicting requirements for sampling over disparate space and time scales. Spatial variability: The spatial distribution of anthropogenic sources is dominated by patterns of production, storage, transport and use. In contrast, geogenic variability is almost entirely controlled by endogenic geological processes, except where surface gas permeability is modulated by soil moisture. Satellite remote sensing solutions will thus have to vary greatly in spatial coverage and resolution to address distributed area sources and point sources alike. Temporal variability: While biogenic sources are dominated by diurnal and seasonal patterns, anthropogenic sources fluctuate over a greater variety of time scales from diurnal, weekly and seasonal cycles, driven by both economic and climatic factors. Geogenic sources typically vary in time scales of days to months (geogenic sources sensu stricto are not fossil fuels but volcanoes, hydrothermal and metamorphic sources). Current ground-based monitoring networks for anthropogenic and geogenic sources record data on minute- to weekly temporal scales. Satellite remote sensing solutions would have to capture temporal variability through revisit frequency or point-and-stare strategies. Space-based remote sensing offers the potential of global coverage by a single sensor. However, no single combination of orbit

Tightly-Coupled GNSS/Vision Using a Sky-Pointing Camera for Vehicle Navigation in Urban Areas.

Gakne, Paul Verlaine; O'Keefe, Kyle

This paper presents a method of fusing the ego-motion of a robot or a land vehicle estimated from an upward-facing camera with Global Navigation Satellite System (GNSS) signals for navigation purposes in urban environments. A sky-pointing camera is mounted on the top of a car and synchronized with a GNSS receiver. The advantages of this configuration are two-fold: firstly, for the GNSS signals, the upward-facing camera will be used to classify the acquired images into sky and non-sky (also known as segmentation). A satellite falling into the non-sky areas (e.g., buildings, trees) will be rejected and not considered for the final position solution computation. Secondly, the sky-pointing camera (with a field of view of about 90 degrees) is helpful for urban area ego-motion estimation in the sense that it does not see most of the moving objects (e.g., pedestrians, cars) and thus is able to estimate the ego-motion with fewer outliers than is typical with a forward-facing camera. The GNSS and visual information systems are tightly-coupled in a Kalman filter for the final position solution. Experimental results demonstrate the ability of the system to provide satisfactory navigation solutions and better accuracy than the GNSS-only and the loosely-coupled GNSS/vision, 20 percent and 82 percent (in the worst case) respectively, in a deep urban canyon, even in conditions with fewer than four GNSS satellites.

The main goal of this Nordic Nuclear Safety Research Council (NKS) project is to produce guidance for how to use human reliability analysis (HRA) to strengthen overall safety. The project consists of two substudies: The Nordic Point of View - A User Needs Analysis, and The American Point of View - Insights of How the US Nuclear Industry Works with HRA. The purpose of the Nordic Point of View study was a user needs analysis that aimed to survey current HRA practices in the Nordic nuclear industry, with the main focus being to connect HRA to system design. In this study, 26 Nordic (Swedish and Finnish) nuclear power plant specialists with research, practitioner, and regulatory expertise in HRA, PRA, HSI, and human performance were interviewed. This study was completed in 2009. This study concludes that HRA is an important tool when dealing with human factors in control room design or modernizations. The Nordic Point of View study showed areas where the use of HRA in the Nordic nuclear industry could be improved. To gain more knowledge about how these improvements could be made, and what improvements to focus on, the second study was conducted. The second study is focused on the American nuclear industry, which has many more years of experience with risk assessment and human reliability than the Nordic nuclear industry. Interviews were conducted to collect information to help the author understand the similarities and differences between the American and the Nordic nuclear industries, and to find data regarding the findings from the first study. The main focus of this report is to identify potential HRA improvements based on the data collected in the American Point of View survey. (Author)

Point-of-views representation for hypothetical reasoning: application to decision-aid

International Nuclear Information System (INIS)

Diaz, Antoine

1992-01-01

Most of the knowledge based Decision Support Systems must deal with two difficulties in problem solving representation: reasoning with incomplete knowledge and managing contradictory reasoning. We propose a method which answers the question of reasoning revision when a contradiction occurs, while preserving the functionalities of the De Kleer's ATMS System for simulating hypothetical reasoning. As a matter of fact, these functionalities are particularly suitable for decision aiding problems. In order to formalize the ATMS, we use a resolution method called Cat-resolution (Cayrol and Tayrac). This method allows the computation of ATMS functions relating to a set of propositional clauses by saturating this set. Owing to this choice, we can use the same principles as ATMS on the saturation trace. Each clause in the saturated set can be linked to the sets of initial clauses justifying its derivation by Cat-resolution. The reasoning inconsistency is now managed. First the user can identify the source of the inconsistency thanks to the empty clause explanation. Then he can try to restore the reasoning consistency by relaxing at least one of the initial clauses justifying the empty clause. The computation of 'partial' ATMS, representing a point of view in the decision-making problem, is more effective owing to the justifications of the derived clauses. (author) [fr

Full Text Available ABSTRACT This article briefly discusses the role of expansions for construing the characters’ identities and personality traits in Oscar Wilde’s novel The Picture of Dorian Gray and its translation, made by João do Rio, and adaptations, made by Clarice Lispector and Claudia Lopes, into Brazilian Portuguese. The discursive configuration or narrative axis that unveils the narrative point of view is the central linguistic realization of the discussion. The paper also problematizes the concept of omission and rewriting in the literary translation context, asserting that these kinds of (retextualizations may create negative cultural impacts on the target-text reader. The discussion is informed by the principles of systemic-functional grammar and its contributions to literary translation, especially the concepts of projection and clause complex.

2016-12-01

Full Text Available Extraction and analysis of building façades are key processes in the three-dimensional (3D building reconstruction and realistic geometrical modeling of the urban environment, which includes many applications, such as smart city management, autonomous navigation through the urban environment, fly-through rendering, 3D street view, virtual tourism, urban mission planning, etc. This paper proposes a building facade pieces extraction and simplification algorithm based on morphological filtering with point clouds obtained by a mobile laser scanner (MLS. First, this study presents a point cloud projection algorithm with high-accuracy orientation parameters from the position and orientation system (POS of MLS that can convert large volumes of point cloud data to a raster image. Second, this study proposes a feature extraction approach based on morphological filtering with point cloud projection that can obtain building facade features in an image space. Third, this study designs an inverse transformation of point cloud projection to convert building facade features from an image space to a 3D space. A building facade feature with restricted facade plane detection algorithm is implemented to reconstruct façade pieces for street view service. The results of building facade extraction experiments with large volumes of point cloud from MLS show that the proposed approach is suitable for various types of building facade extraction. The geometric accuracy of building façades is 0.66 m in x direction, 0.64 in y direction and 0.55 m in the vertical direction, which is the same level as the space resolution (0.5 m of the point cloud.

The inadequate number of health care providers, particularly nurses, in underserved areas is one of the biggest challenges for health policymakers. There is a scarcity of research in Jordan about factors that affect nurse staffing and retention in underserved areas. To elucidate the views of staff nurses working in underserved areas, directors of health facilities in underserved areas and key informants from the policy and education arena on issues of staffing and retention of nurses in underserved areas. An exploratory study using a qualitative approach with semi-structured interviews was utilized to elucidate the views of 22 key informants from the policy and education arena, 11 directors of health centers, and 19 staff nurses on issues that contribute to low staffing and retention of nurses in underserved areas. The five stage 'framework approach' proposed by Bryman et al. (1993) was utilized for data analysis. Nursing shortage in underserved areas in Jordan are exacerbated by a lack of financial incentives, poor transportation and remoteness of these areas, bad working conditions, and lack of health education institutions in these areas, as well as by opportunities for internal and external migration. Young Jordanian male nurses usually grab any opportunity to migrate and work outside the country to improve their financial conditions; whereas, female nurses are more restricted and not encouraged to travel abroad to work. Several strategies are suggested to enhance retention in these areas, such as promoting financial incentives for staff to work there, enhancing the transportation system, and promoting continuous and academic education. Nurses' administrators and health care policy makers could utilize the findings of the present study to design and implement comprehensive interventions to enhance retention of staff in underserved areas.

The paper centers on environmental practical ethic point of views according to a professional ecologist. Ecology and the science of Socio-ecology are defined. The framework of the Millennium Ecosystem Assessment initiative (MA 2003), including the use of ecosystems as the environmental unit of analysis, ecosystem services and human well-being as the center for assessment are discussed. Common-pool resources (CPR) and the allegory of the tragedy of the commons are used to illustrate main scientific and ethical environmental approaches, and above all to highlight the case of climate change, considering ″air-atmosphere″ as a CPR. The need to adopt practical personal environmental ethical positions is highlighted. Furthermore, on climate change, a discussion on the need to develop environmental and socio-ecological polycentric approaches: top-down and bottom-up, is included. An updated discussion on the concept of conservation, including main scientific and ethic points of view, is presented. Pope Francis's Encyclical, Laudato Si', is used to highlight environmental, socio-ecological and ethical aspects behind the comprehensive concept of Integral Ecology. The paper ends with a short synthesis on Earth modern unseen and astonishing environmental and socio-ecological rates of changes, and identifying the main barriers for personal environmental engagement. A call is done regarding the urgent need for socio-environmental ethic personal engagement and collective actions.

Clinical evaluation is very important in the educational system of nursing. One of the most common methods of clinical evaluation is evaluation by the teacher, but the challenges that students would face in this evaluation method, have not been mentioned. Thus, this study aimed to explore the experiences and views of nursing students about the challenges of teacher-based clinical evaluation. This study was a descriptive qualitative study with a qualitative content analysis approach. Data were gathered through semi-structured focused group sessions with undergraduate nursing students who were passing their 8 th semester at Rafsanjan University of Medical Sciences. Date were analyzed using Graneheim and Lundman's proposed method. Data collection and analysis were concurrent. According to the findings, "factitious evaluation" was the main theme of study that consisted of three categories: "Personal preferences," "unfairness" and "shirking responsibility." These categories are explained using quotes derived from the data. According to the results of this study, teacher-based clinical evaluation would lead to factitious evaluation. Thus, changing this approach of evaluation toward modern methods of evaluation is suggested. The finding can help nursing instructors to get a better understanding of the nursing students' point of view toward this evaluation approach and as a result could be planning for changing of this approach.

Full Text Available Trans-orbital orbitocranial penetrating injury (TOPI by a foreign body is an extremely rare compound head injury having a potential to cause major morbidity and mortality. Preoperative radiological imaging by CT scan is very important for operative guidance, but in remote area where CT scan is not available, the patient is generally referred to tertiary level. Here we present a case which was dealt successfully without CT scan, only on the basis of stable clinical status and X-rays. We present a case of a 35-year-old man who had an accidental injury (fall from height by rod. Immediate X-ray (anteroposterior and lateral views revealed that the pointed end of the foreign body (rod was inside the ipsilateral anterior fossa via basifrontal bone up to frontal vertex, not crossing the midline. CT scan was not available and his vitals with GCS were normal (15/15. He was operated with the help of an ophthalmic surgeon by right frontotemporal craniotomy. The patient was discharged on 10 th day without any neurological deficit except restricted right eyeball movement to superolateral and ptosis. The restricted eyeball movements recovered after third month of follow up with remnant ptosis for 2 years. This case highlights an unusual case, direct visualization and repair of brain structures with higher antibiotics can save the life even in remote areas where CT scan is still not available only on the basis of stable GCS and X-rays.

quantitative methods exist for evaluating uncertainty—for example, Monte Carlo simulation—and such methods work very well when the AN is in full control of the data collection and model-building processes. In many cases, however, the AN is not in control of these processes. In this article we develop a simple...... method that a DM can employ in order to evaluate the process of decision support from a statistical point-of-view. We call this approach the “Statistical Value Chain” (SVC): a consecutive benchmarking checklist with eight steps that can be used to evaluate decision support seen from a statistical point-of-view....

Full Text Available Jengki architecture is one of Indonesian post-colonial architecture style popular in 1950 to 1970. Most study of Jengki was done in Jakarta, Semarang, and Malang. In Bandung, there is no written record of Jengki identification or documentation found. This paper tries to recognize and document Jengki typology in Bandung as a preliminary study on its presences, and its variant, in the city. It also tries to look at this typology from heritage point of view, whether there is significance in accordance to heritage criteria. Using site survey and Google street view, data were collected and elaborated in table to recognize Jengki traits in a suspected building. Building’s significances were then reviewed using criteria mentioned in local legislation.  It is found that not all suspected Jengki building contain all Jengki traits rather more late modern Indonesian character.  Private buildings were assessed to have less heritage value, while public building retains more. Deeper study and documentation on Jengki in Bandung are still needed to legitimate Jengki as heritage since there is no study ever done previously on this issue

Risks associated with adolescent Internet use include exposure to inappropriate information and privacy violations. Privacy expectations and policies have changed over time. Recent Facebook security setting changes heighten these risks. The purpose of this study was to investigate views and experiences with Internet safety and privacy protection among older adolescent females at two time points, in 2009 and 2012. Two waves of focus groups were conducted, one in 2009 and the other in 2012. During these focus groups, female university students discussed Internet safety risks and strategies and privacy protection. All focus groups were audio recorded and manually transcribed. Qualitative analysis was conducted at the end of each wave and then reviewed and combined in a separate analysis using the constant comparative method. A total of 48 females participated across the two waves. The themes included (1) abundant urban myths, such as the ability for companies to access private information; (2) the importance of filtering one's displayed information; and (3) maintaining age limits on social media access to avoid younger teens' presence on Facebook. The findings present a complex picture of how adolescents view privacy protection and online safety. Older adolescents may be valuable partners in promoting safe and age-appropriate Internet use for younger teens in the changing landscape of privacy. Copyright © 2014. Published by Elsevier Inc.

Full Text Available Carlo Petrini Bioethics Unit, Office of the President, National Institute of Health, Rome, Italy Abstract: A review of the European Union (EU regulations concerning blood, tissues, and cells of human origin is under way in the EU. From the ethical point of view, the non-remuneration of donations and the ban on deriving gain from human biological materials are of particular significance. While the basic ethical principles involved in the procurement, preservation, and use of these materials are the same, their practical application should be adapted to the specific context of each material. In the case of donation and use of blood, in particular, the issue of legitimate reimbursements to donors and for transfusion centers has to be managed in accordance with the principle of non-commercialization. There is also a need for strict rules to avoid possible commercial spillover effects from blood-derived products. The author proposes ethical criteria regarding reimbursements to donors, costs associated with processing, and the development (and possible marketing of products.

Tenenbaum, A.; Nguyen Van Doan

1976-01-01

The effect of thermal vibrations on atomic collision focusing was studied with the view to demonstrate that such collisions may induce point defect migration through the crystal. The persistence of the phenomenon of focused atomic collisions in a crystal at thermal equilibrium was studied, using a computer simulation by the Molecular Dynamics Technique. In the temperature range (0 to 500K) matter and momentum transfers in c.f.c. crystals proceed mainly by focused collisions along and directions. Their contribution to the induced migration of radiation defects was determined from the threshold energy of every primary able to be involved in the process. As an example, the quantitative model is applied to electron irradiation along the crystallographic directions [fr

Art therapy is used in the whole field of psycho-oncological maintenance to support coping mechanisms with creative techniques. Previous studies stated effects of art therapy just by referring to the participants' ratings. This study wants to extend the perspective by including the views of all involved parties--participating patients, dropouts, art therapist and supervisor. We developed and tested an art therapy programme for cancer patients. The participants' and dropouts' ratings were documented by using a questionnaire with open and closed questions upon completion of the intervention. The art therapist and the supervisor described their personal point of view. 74 patients took part in the intervention whereof 18 dropped out. Of these, 8 could be interviewed regarding the reasons for not participating further in the study. The dropouts evaluated the intervention positively(4/8) or could not make a final statement (3/8). 55 questionnaires were available from the 56 participants. They described the importance of the programme in several ways. Most of all, they reported of: stimulation of imagination (50/55), emotional stabilisation(48/55), enlargement of means of expression (45/55) and contact with other patients (42/55). The dropouts named several reasons for their decision to cancel: too intense focus on the disease(N = 3), modern drawing (N = 1), too much talks (N = 1) and too much sketching (N = 1) were some points of criticism. The art therapist as well as the supervisor emphasized activation as a main outcome for the participants. Positive effects of the intervention programme highlight the importance of establishing an art therapy in ambulant care. It enlarges the range of psychosocial maintenance and enables oncological patients to cope with the disease and its consequences with artistic means.

Stages in learning motor synergies: a view based on the equilibrium-point hypothesis.

Science.gov (United States)

Latash, Mark L

2010-10-01

This review describes a novel view on stages in motor learning based on recent developments of the notion of synergies, the uncontrolled manifold hypothesis, and the equilibrium-point hypothesis (referent configuration) that allow to merge these notions into a single scheme of motor control. The principle of abundance and the principle of minimal final action form the foundation for analyses of natural motor actions performed by redundant sets of elements. Two main stages of motor learning are introduced corresponding to (1) discovery and strengthening of motor synergies stabilizing salient performance variable(s) and (2) their weakening when other aspects of motor performance are optimized. The first stage may be viewed as consisting of two steps, the elaboration of an adequate referent configuration trajectory and the elaboration of multi-joint (multi-muscle) synergies stabilizing the referent configuration trajectory. Both steps are expected to lead to more variance in the space of elemental variables that is compatible with a desired time profile of the salient performance variable ("good variability"). Adjusting control to other aspects of performance during the second stage (for example, esthetics, energy expenditure, time, fatigue, etc.) may lead to a drop in the "good variability". Experimental support for the suggested scheme is reviewed. Copyright © 2009 Elsevier B.V. All rights reserved.

2004-08-01

Within the deinstitutionalization process of a large psychiatric hospital, the development of two cohorts of patients with chronic schizophrenia is compared over a two-year period: patients living in the hospital's nursing-home area (n = 50) vs. patients already released to two social therapeutic hostels (n = 51). Results of the cohort study were compared with assessments of nurses working in the nursing home (n = 55), focusing on their subjective views of the deinstitutionalization process and its impact on their working conditions. Patients are assessed through yearly home-visits in their place of residence. The instruments used measure several outcome parameters: psychopathology, social disabilities, subjective quality of life, and normative needs for care. Concurrent staff assessments were conducted using standardized survey instruments focusing on current working conditions and quality of teamwork. Nineteen nurses participated in qualitative interviews evaluating the deinstitutionalization process. For all measures, patients living in the nursing home show significantly worse outcomes. Furthermore, during the study period 34 % experienced a change in their living situation with which they were dissatisfied. Needs for care and the number of areas of "unmet" need increased significantly for this subgroup. Patients living in social therapeutic hostels demonstrate stable levels of psychopathological symptoms, social disabilities, and needs for care. Assessments indicating a deterioration in patients' subjective quality of life focus mainly on areas important for social contacts. Regarding "personal concerns" and "insecurity at work", ratings from nursing home staff were significantly worse than those of a reference group from several other health care institutions (n = 224). Staff showed a tendency to give higher ratings for their opportunities to participate in decisions, in contrast with the low ratings for chances to improve their knowledge in the workplace, a

Downscaling remotely sensed imagery using area-to-point cokriging and multiple-point geostatistical simulation

Tang, Yunwei; Atkinson, Peter M.; Zhang, Jingxiong

2015-03-01

A cross-scale data integration method was developed and tested based on the theory of geostatistics and multiple-point geostatistics (MPG). The goal was to downscale remotely sensed images while retaining spatial structure by integrating images at different spatial resolutions. During the process of downscaling, a rich spatial correlation model in the form of a training image was incorporated to facilitate reproduction of similar local patterns in the simulated images. Area-to-point cokriging (ATPCK) was used as locally varying mean (LVM) (i.e., soft data) to deal with the change of support problem (COSP) for cross-scale integration, which MPG cannot achieve alone. Several pairs of spectral bands of remotely sensed images were tested for integration within different cross-scale case studies. The experiment shows that MPG can restore the spatial structure of the image at a fine spatial resolution given the training image and conditioning data. The super-resolution image can be predicted using the proposed method, which cannot be realised using most data integration methods. The results show that ATPCK-MPG approach can achieve greater accuracy than methods which do not account for the change of support issue.

How to successfully implement extended producer responsibility: considerations from an economic point of view.

Science.gov (United States)

Wiesmeth, Hans; Häckl, Dennis

2011-09-01

This paper investigates the concept of extended producer responsibility (EPR) from an economic point of view. Particular importance will be placed on the concept of 'economic feasibility' of an EPR policy, which should guide decision-making in this context. Moreover, the importance of the core EPR principle of 'integrating signals throughout the product chain' into the incentive structure will be demonstrated with experiences from Germany. These examples refer to sales packaging consumption, refillable drinks packages and waste electrical and electronic equipment collection. As a general conclusion, the interaction between economic principles and technological development needs to be observed carefully when designing incentive-compatible EPR policies.

Full Text Available   The possibility or impossibility of vision of God is exciting and complicated question which has allocated itself various views along Islamic thought. What become obvious from Islamic Gnostics sayings and shia imam ’s demonstration and statements is that they know the sensible vision and intellectual vision of God impossible.   They just know allowable the heartfelt vision which is the result of purity and safeness of inner faculties and therefore the verses of Quran about the vision of God or prophet ’s requesting about sighting of God have interpreted to heartfelt intuition.   This paper briefly reviews some Islamic theologies ideas with respect to their Quranic demonstrations and commentators views on this issue and comparing their understandings from Quranic verses whit each other specially verse 143 of sura Araf, in addition to speak about the meaning of intuition vision and its truth, its order, how human can be achieved that position with respect to three principles: "unity of being, velayat, love" and whit the centrality of holy Quran, hadiths and imam ’s statements. Therefore in this paper it will become obvious what is the meaning of intuition vision from Gnostics point of view and it’s the result of manifestation of God ’s attributes which man can achieve to intuition position .

Computer vision and photogrammetric techniques have been widely applied to digital imagery producing high density 3D point clouds. Using thermal imagery as input, the same techniques can be applied to infrared data to produce point clouds in 3D space, providing surface temperature information. The work presented here is an evaluation of the accuracy of 3D reconstruction of point clouds produced using thermal imagery. An urban scene was imaged over an area at the Naval Postgraduate School, Monterey, CA, viewing from above as with an airborne system. Terrestrial thermal and RGB imagery were collected from a rooftop overlooking the site using a FLIR SC8200 MWIR camera and a Canon T1i DSLR. In order to spatially align each dataset, ground control points were placed throughout the study area using Trimble R10 GNSS receivers operating in RTK mode. Each image dataset is processed to produce a dense point cloud for 3D evaluation.

AUTOMATIC BUILDING OUTLINING FROM MULTI-VIEW OBLIQUE IMAGES

Directory of Open Access Journals (Sweden)

J. Xiao

2012-07-01

Full Text Available Automatic building detection plays an important role in many applications. Multiple overlapped airborne images as well as lidar point clouds are among the most popular data sources used for this purpose. Multi-view overlapped oblique images bear both height and colour information, and additionally we explicitly have access to the vertical extent of objects, therefore we explore the usability of this data source solely to detect and outline buildings in this paper. The outline can then be used for further 3D modelling. In the previous work, building hypotheses are generated using a box model based on detected façades from four directions. In each viewing direction, façade edges extracted from images and height information by stereo matching from an image pair is used for the façade detection. Given that many façades were missing due to occlusion or lack of texture whilst building roofs can be viewed in most images, this work mainly focuses on improve the building box outline by adding roof information. Stereo matched point cloud generated from oblique images are combined with the features from images. Initial roof patches are located in the point cloud. Then AdaBoost is used to integrate geometric and radiometric attributes extracted from oblique image on grid pixel level with the aim to refine the roof area. Generalized contours of the roof pixels are taken as building outlines. The preliminary test has been done by training with five buildings and testing around sixty building clusters. The proposed method performs well concerning covering the irregular roofs as well as improve the sides location of slope roof buildings. Outline result comparing with cadastral map shows almost all above 70% completeness and correctness in an area-based assessment, as well as 20% to 40% improvement in correctness with respect to our previous work.

Cacao diseases: a global perspective from an industry point of view.

Science.gov (United States)

Hebbar, Prakash K

2007-12-01

ABSTRACT Diseases of cacao, Theobroma cacao, account for losses of more than 30% of the potential crop. These losses have caused a steady decline in production and a reduction in bean quality in almost all the cacao-producing areas in the world, especially in small-holder farms in Latin America and West Africa. The most significant diseases are witches' broom, caused by Moniliophthora perniciosa, which occurs mainly in South America; frosty pod rot, caused by M. roreri, which occurs mainly in Central and northern South America; and black pod disease, caused by several species of Phytophthora, which are distributed throughout the tropics. In view of the threat that these diseases pose to the sustainability of the cacao crop, Mars Inc. and their industry partners have funded collaborative research involving cacao research institutes and governmental and nongovernmental agencies. The objective of this global initiative is to develop short- to medium-term, low-cost, environmentally friendly disease-management strategies until disease tolerant varieties are widely available. These include good farming practices, biological control and the rational or minimal use of chemicals that could be used for integrated pest management (IPM). Farmer field schools are used to get these technologies to growers. This paper describes some of the key collaborative partners and projects that are underway in South America and West Africa.

2016-01-01

Orthopedic surgical education is evolving as educators search for new ways to enhance surgical skills training. Orthopedic educators should seek new methods and technologies to augment and add value to real-time orthopedic surgical experience. This paper describes a protocol whereby we have started to capture and evaluate specific orthopedic milestone procedures with a GoPro® point-of-view video camera and a dedicated video reviewing website as a way of supplementing the current paradigm in surgical skills training. We report our experience regarding the details and feasibility of this protocol. Upon identification of a patient undergoing surgical fixation of a hip or ankle fracture, an orthopedic resident places a GoPro® point-of-view camera on his or her forehead. All fluoroscopic images acquired during the case are saved and later incorporated into a video on the reviewing website. Surgical videos are uploaded to a secure server and are accessible for later review and assessment via a custom-built website. An electronic survey of resident participants was performed utilizing Qualtrics software. Results are reported using descriptive statistics. A total of 51 surgical videos involving 23 different residents have been captured to date. This includes 20 intertrochanteric hip fracture cases and 31 ankle fracture cases. The average duration of each surgical video was 1 hour and 16 minutes (range 40 minutes to 2 hours and 19 minutes). Of 24 orthopedic resident surgeons surveyed, 88% thought capturing a video portfolio of orthopedic milestones would benefit their education. There is a growing demand in orthopedic surgical education to extract more value from each surgical experience. While further work in development and refinement of such assessments is necessary, we feel that intraoperative video, particularly when captured and presented in a non-threatening, user friendly manner, can add significant value to the present and future paradigm of orthopedic surgical

2012-07-01

The paper presents a comprehensive method for automated extraction and delineation of building outlines in densely built-up areas. A novel approach to outline reconstruction is the use of geocoded building address points. They give information about building location thus highly reduce task complexity. Reconstruction process is executed on 3D point clouds acquired by airborne laser scanner. The method consists of three steps: building detection, delineation and contours refinement. The algorithm is tested against a data set that presents the old market town and its surroundings. The results are discussed and evaluated by comparison to reference cadastral data.

Target validation for FCV technology development in Japan from energy competition point of view

International Nuclear Information System (INIS)

ENDO Eiichi

2006-01-01

The objective of this work is to validate the technical targets in the governmental hydrogen energy road-map of Japan by analyzing market penetration of fuel cell vehicle(FCV)s and effects of fuel price and carbon tax on it from technology competition point of view. In this analysis, an energy system model of Japan based on MARKAL is used. The results of the analysis show that hydrogen FCVs could not have cost-competitiveness until 2030 without carbon tax, including the governmental actual plan of carbon tax. However, as the carbon tax rate increases, instead of conventional vehicles including gasoline hybrid electric vehicle, hydrogen FCVs penetrate to the market earlier and more. By assuming higher fuel price and severer carbon tax rate, market share of hydrogen FCVs approaches to the governmental goal. This suggests that cheaper vehicle cost and/or hydrogen price than those targeted in the road-map is required. At the same time, achievement of the technical targets in the road-map also allows to attain the market penetration target of hydrogen FCVs in some possible conditions. (authors)

Full Text Available Even though the poor with a lower income than poverty line though hired to be paid constitute the majority of the whole population in many countries, they have not been researched sufficiently. Working poor people can not reach the sufficient level of income to meet their expenses as a result of familial circumstances like insufficient education, divorce, excessiveness of the number of children, loss of a spouse as well as working for low wage due to the labour market. This research is supposed to be about poor people working as wage earners in informal sector in Denizli. 100 apartment doorkeepers, 100 house cleaners and 100 baby sitters have been included into the research as its samples. This research is concerned with the point of view about poverty of working poor people, their strategies of coping with poverty and their social relations

Radical prostatectomy: evolution of surgical technique from the laparoscopic point of view

Xavier Cathelineau

2010-04-01

Full Text Available PURPOSE: To review the literature and present a current picture of the evolution in radical prostatectomy from the laparoscopic point of view. MATERIALS AND METHODS: We conducted an extensive Medline literature search. Articles obtained regarding laparoscopic radical prostatectomy (LRP and our experience at Institut Montsouris were used for reassessing anatomical and technical issues in radical prostatectomy. RESULTS: LRP nuances were reassessed by surgical teams in order to verify possible weaknesses in their performance. Our basic approach was to carefully study the anatomy and pioneer open surgery descriptions in order to standardized and master a technique. The learning curve is presented in terms of an objective evaluation of outcomes for cancer control and functional results. In terms of technique-outcomes, there are several key elements in radical prostatectomy, such as dorsal vein control-apex exposure and nerve sparing with particular implications in oncological and functional results. Major variations among the surgical teams' performance and follow-up prevented objective comparisons in radical prostatectomy. The remarkable evolution of LRP needs to be supported by comprehensive results. CONCLUSIONS: Radical prostatectomy is a complex surgical operation with difficult objectives. Surgical technique should be standardized in order to allow an adequate and reliable performance in all settings, keeping in mind that cancer control remains the primary objective. Reassessing anatomy and a return to basics in surgical technique is the means to improve outcomes and overcome the difficult task of the learning curve, especially in minimally access urological surgery.

In a widely circulated document, a group of French renowned scientists from French Academia of sciences suggests that the risk of cancer induced by ionizing radiation is for the low doses smaller by unit than this one established for strong doses that is to say for the doses where an effect has been demonstrated by epidemiological studies. It suggests particularly that at very low doses, the excess of cancers could be null even negative. Although there is considerable uncertainty about the carcinogenic effect of low doses, we believe that the authors have not provided a convincing argument in favor of their hypotheses, from a quantitative point of view or a qualifying one. The main argument of the authors is based on biological arguments demonstrating that very low doses of radiation induce lesions in a limited number of cells, making possible the elimination of these cells either by cell death, or by another mechanism. Thus, one would be led to define a threshold below which there is no increased cancer risk. But the arguments do not seem sufficient to draw such conclusions. (N.C.)

Zero-point oscillations, zero-point fluctuations, and fluctuations of zero-point oscillations

International Nuclear Information System (INIS)

Khalili, Farit Ya

2003-01-01

Several physical effects and methodological issues relating to the ground state of an oscillator are considered. Even in the simplest case of an ideal lossless harmonic oscillator, its ground state exhibits properties that are unusual from the classical point of view. In particular, the mean value of the product of two non-negative observables, kinetic and potential energies, is negative in the ground state. It is shown that semiclassical and rigorous quantum approaches yield substantially different results for the ground state energy fluctuations of an oscillator with finite losses. The dependence of zero-point fluctuations on the boundary conditions is considered. Using this dependence, it is possible to transmit information without emitting electromagnetic quanta. Fluctuations of electromagnetic pressure of zero-point oscillations are analyzed, and the corresponding mechanical friction is considered. This friction can be viewed as the most fundamental mechanism limiting the quality factor of mechanical oscillators. Observation of these effects exceeds the possibilities of contemporary experimental physics but almost undoubtedly will be possible in the near future. (methodological notes)

This subgroup has been charged with the task of reconsidering these areas from the point of view of useability in the ISABELLE experimental program. As a result we have developed an ordered list of suggested improvements to each of the areas. The list is presented area-by-area, after some introductory remarks on the design considerations behind the present areas. The purpose of the list is to indicate the eventual scope of ISABELLE experimental areas, not to suggest that these upgrades should be put in place now. Indeed, although most of these additions will be needed regardless of which experiments are carried out, we think it prudent to wait for experiment approvals before the final design and installation of the suggested improvements

-the-art, reliable, automated mechatronics-material flow system with its single control engineering system provides the academic staff with up-to-date research facilities, and enables the students to study sophisticated equipment and systems that could also operate under industrial conditions, thus offering knowledge that can be efficiently utilised in the industry after graduation. The laboratory measurements of the programme in logistics engineering are performed in this laboratory, and they are supplemented by the theoretical and practical measurements in the ‘Robotic Technology Assembly Laboratory', the ‘Power Electronics Laboratory', the ‘Mechatronics Laboratory', the ‘CAD/CAM Laboratory' and the ‘Acoustics and Product Laboratory'. The bodies of knowledge connected with environment protection and sustainable development can be grouped around three large topic areas. In environmental economics the objective is to present the corporate-organisational aspects of environmental management. Putting environmental management in the focal point, the objective of the programme is to impart knowledge that can be utilised in practice which can be used to shift the relation between the organisation and its environment in the direction of sustainability. The tools include environmental controlling, environmental marketing and various solutions of environmental performance evaluation. The second large topic area is globalization and its logistic aspects. In the field of global logistics the following knowledge carries special weight: logistic challenges in a globalised world; the concept of global logistics, its conditions and effects; delayed manufacture, assembly, packaging; the economic investigation of delayed assembly; globalised purchase and distribution in logistics; the logistic features of the globalised production supply/distribution chain; meta-logistics systems; logistics-related EU harmonisation issues; the effect of e-commerce on the global logistic system; logistic

Full Text Available Symbol from the perspective of rhetorical word, is phrase or sentence that apparent meaning, also inspires to reader a wide range of semantic.Since exploring the complex social and political ideas in the most mysticalway and indirectreflectionsocial and political thoughts symbolically is easier, so the symbol and symbolism especially in Persian literatureespeciallyin the realm of Persian poetry, has a special appearance.In addition to the factors mentioned in the contemporary literature, according familiar in literature and the emergence of particular schools interest toambiguoussymbolization has spreadfurther, especially the symbol has all the features of art ambiguity in the poem and it isone the major factors causing uncertainty.Thus, the precise definitions and symbols of contemporary poetry could be dominant in the unwinding ambiguous symbol detection of cryptic allusions and metaphors that matches the cursor symbol to help readers.In the literature, especially language poetry, the inability of language toreflecting obscure mystical ideas, avoid to directexpression of political and social concerns of the reader in the course of participate to creation ambiguous literary works is the main motivation towards symbol and symbolization.According widespread use of symbol and its different of species can be viewed from different perspectives.The creation of ambiguity is the main purposes of using symbols (especially in poetry, so many poets have tried to achieve this goal have to formation of similar symbols and the explanation and resolution of this issue can open new window for understanding the poetry in front of an audience.In this paper examines the ambiguity of symbols in terms of its precise boundaries are reviewed. Ambiguity is one of the important processes and also is the key Iranian poetry; its means is today poetry. In such poetry ambiguity is a need to explore the new world from a different perspective, or explore this complex world

Collaboration involves direct and open communication and respect for different perspectives. In particular, religious literature has many references to collaboration. This study is a report of knowledge synthesis based on qualitative systematic review by content analysis. The study surveys the concept of collaboration from the Islamic point of view and intends to answer the question, 'Does the Quran deal with the use of collaboration in human activities?' This study was conducted using electronic documents from websites related to Islamic and Quran sciences, such as Howzah.net, Nashriat.ir, Tebyan.net and Google Scholar from 1950 until 2013 by focusing on the keywords, collaboration and Islam, and then retrieving the Islamic document (Quran and Hadith). The language in which the search was conducted was English and Persian. Nearly, 28 articles and 72 books related to this topic were found and after applying the search criteria, only 13% of the references were found to be applicable. In the Quran, collaboration is equivalent to Taavon, and Muslims are requested to collaborate in their affairs and never collaborate with each other for illegal affairs. Islam asserts that everyone requires social relationship in their life. God has enacted mutual rights for people and meeting these requirements is only possible through collaboration and respecting mutual rights.

From February 1991 to October 1992, the U.S. Geological Survey, in cooperation with the Central Utah Water Conservancy District, investigated the hydrology of the Lincoln Point - Bird Island area in the southeast part of Utah Lake, Utah. The investigation included measurements of the discharge of selected springs and measurements of the physical and chemical characteristics of water from selected springs and wells in the LincolnPoint - Bird Island area. This report contains data for twenty-one distinct springs in the study area including two springs beneath the surface of Utah Lake at Bird Island. Data from this study, combined with data from previous studies, indicate that the location of springs in the Lincoln Point - Bird Island area probably is controlled by fractures that are the result of faulting. Measured discharge of springs in the Lincoln Point - Bird Island area ranged from less than 0.01 cubic foot per second to 0.84 cubic foot per second. Total discharge in the study area, including known unmeasured springs and seeps, is estimated to be about 5 cubic feet per second. Reported and measured temperatures of water from springs and wells in the Lincoln Point - Bird Island area ranged from 16.0 degrees Celsius to 36.5 degrees Celsius. Dissolved-solids con-centrations ranged from 444 milligrams per liter to 7,932 milligrams per liter, and pH ranged from 6.3 to 8.1. Physical and chemical characteristics of spring and well water from the west side of Lincoln Point were virtually identical to the physical and chemical characteristics of water from the submerged Bird Island springs, indicating a similar source for the water. Water chemistry, isotope analyses, and geothermometer calculations indicate deep circulation of water discharging from the springs and indicate that the source of recharge for the springs at Lincoln Point and Bird Island does not appear to be localized in the LincolnPoint - Bird Island area.

The German government has decided for the nuclear phase out, but a decision on a strategy for the management of the highly radioactive waste is not defined yet. Partitioning and Transmutation (P&T) could be considered as a technological option for the management of highly radioactive waste, therefore a wide study has been conducted. In the study group objectives for P&T and the boundary conditions of the phase out have been discussed. The fulfillment of the given objectives is analyzed from neutronics point of view using simulations of a molten salt reactor with fast neutron spectrum. It is shown that the efficient transmutation of all existing transuranium isotopes would be possible from neutronic point of view in a time frame of about 60 years. For this task three reactors of a mostly new technology would have to be developed and a twofold life cycle consisting of a transmuter operation and a deep burn phase would be required. A basic insight for the optimization of the time duration of the deep burn phase is given. Further on, a detailed balance of different isotopic inventories is given to allow a deeper understanding of the processes during transmutation in the molten salt fast reactor. The effect of modeling and simulation is investigated based on three different modeling strategies and two different code versions.

Access point (AP) is part of a Wireless Local Access Network (WLAN) with its communications using WiFi. AP is used to transmit and receive data to users/clients. The ability of AP to serve users/clients depends on many factors. Moreover, if AP is applied in conditions inside the building. In this study, AP is installed at two points inside the building and then measured in the form of the received signal level (RSL) and service coverage area. One AP measured its performance by 26 measurement points and the other AP measured its performance by 20 measurement points. When AP has measured its performance then another AP position is switched off. Based on the measurement result, the received signal level value is the highest value is about -47 dBm at a distance of 3.2 m, while the lowest is about -79 dBm at a 9.21 m because it is on barrier 2 walls. While based on service coverage area, the area which is far away from the AP then the quality of service becomes bad because the transmitted signal is weakening caused by the distance and the loss of the wall.

Lacunarity, a measure of the spatial distribution of the empty space is found to be a useful descriptive quantity of the forest structure. Its calculation, based on laser-scanned point clouds, results in a four-dimensional data set. The evaluation of results needs sophisticated tools and visualization techniques. To simplify the evaluation, it is straightforward to use approximation functions fitted to the results. The lacunarity function L(r), being a measure of scale-independent structural properties, has a power-law character. Previous studies showed that log(log(L(r))) transformation is suitable for analysis of spatial patterns. Accordingly, transformed lacunarity functions can be approximated by appropriate functions either in the original or in the transformed domain. As input data we have used a number of laser-scanned point clouds of various forests. The lacunarity distribution has been calculated along a regular horizontal grid at various (relative) elevations. The lacunarity data cube then has been logarithm-transformed and the resulting values became the input of parameter estimation at each point (point of interest, POI). This way at each POI a parameter set is generated that is suitable for spatial analysis. The expectation is that the horizontal variation and vertical layering of the vegetation can be characterized by this procedure. The results show that the transformed L(r) functions can be typically approximated by exponentials individually, and the residual values remain low in most cases. However, (1) in most cases the residuals may vary considerably, and (2) neighbouring POIs often give rather differing estimates both in horizontal and in vertical directions, of them the vertical variation seems to be more characteristic. In the vertical sense, the distribution of estimates shows abrupt changes at places, presumably related to the vertical structure of the forest. In low relief areas horizontal similarity is more typical, in higher relief areas

The study of a comparative analysis of distinct multiplex and fault-tolerant configurations for a PLC-based safety system from a reliability point of view is presented. It considers simplex, duplex and fault-tolerant triple redundancy configurations. The standby unit in case of a duplex configuration has a failure rate which is k times the failure rate of the standby unit, the value of k varying from 0 to 1. For distinct values of MTTR and MTTF of the main unit, MTBF and availability for these configurations are calculated. The effect of duplexing only the PLC module or only the sensors and the actuators module, on the MTBF of the configuration, is also presented. The results are summarized and merits and demerits of various configurations under distinct environments are discussed.

Full Text Available Early warning system (EWS based on a reliable forecasting process has become a critical component of the management of large complex industrial projects in the globalized transnational environment. The purpose of this research is to critically analyze the forecasting methods from the point of view of early warning, choosing those useful for the construction of EWS. This research addresses complementary techniques, using Bayesian Networks, which addresses both uncertainties and causality in project planning and execution, with the goal of generating early warning signals for project managers. Even though Bayesian networks have been widely used in a range of decision-support applications, their application as early warning systems for project management is still new.

The IS approach for the JNC-1 site was implemented in August 2008, and this was the first experience in the world. This IS approach aimed not only to improve efficiency and effectiveness of safeguards but also to reduce burden of the plant operation by improvement of efficiency of the inspection activity. It was planned to review effectiveness of this new approach after three years from implementation. And JAEA also evaluated effects by application of the IS approach for two MOX fuel facilities in the JNC-1 site based on the three years experiences from the operator's view point. As the result of evaluation, it was confirmed that there were some difference of benefits by application of the IS approach depending on features of the facility, automation level of equipment and advance level of safeguards systems.

2018-01-01

A solitary patient with symptoms similar to those of shortlasting unilateral neuralgiform conjunctival injection and tearing (SUNCT) was first mentioned in 1978. The term SUNCT was first used in 1991. SUNCT is an acronym; the “S” signifies “Shortlasting”; the “U” symbolizes “Unilateral”; “N” stands for “Neuralgiform”; the “C” for “Conjunctival injection”; and “T” for “Tearing.” The term short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms were marketed in 2004. The terminology and new view points are discussed and nosography proposal for SUNCT is presented. PMID:29740387

Cancer Theory from Systems Biology Point of View

Science.gov (United States)

Wang, Gaowei; Tang, Ying; Yuan, Ruoshi; Ao, Ping

In our previous work, we have proposed a novel cancer theory, endogenous network theory, to understand mechanism underlying cancer genesis and development. Recently, we apply this theory to hepatocellular carcinoma (HCC). A core endogenous network of hepatocyte was established by integrating the current understanding of hepatocyte at molecular level. Quantitative description of the endogenous network consisted of a set of stochastic differential equations which could generate many local attractors with obvious or non-obvious biological functions. By comparing with clinical observation and experimental data, the results showed that two robust attractors from the model reproduced the main known features of normal hepatocyte and cancerous hepatocyte respectively at both modular and molecular level. In light of our theory, the genesis and progression of cancer is viewed as transition from normal attractor to HCC attractor. A set of new insights on understanding cancer genesis and progression, and on strategies for cancer prevention, cure, and care were provided.

Using a newly developed whole body gamma scanner (Toshiba-RDA-601), the authors recorded whole body bone scans in 5 patients (two normal, osteomalacia, bone metastases of prostate cancer and bone metastases of breast cancer), and compared the regular scintiscans with those of bird's-eye view images which were made with the data processor of the scanner. The scans were started about 2 hours after intravenous injection of 3 to 8 mCi of sup(99m)Tc-monofluorophosphate stannous fluoride. The recorded bird's-eye view scans displayed the skeletal system vividly as they were, and the distribution of radioactivity semiquantitatively. It was concluded that the bird'eye view scan is superior to the regular scan, in view of the point that it expresses the distribution of radioactivity semiquantitatively and enables one to know the amount of abnormally accumulated radioactivities by measuring the height of the peak of the diseased area, although this is very difficult in the regular scan. More clinical studies are needed in order to determine which is better for detecting abnormal part clinically.

Use of wind pumps in Indian farms: A point of view

International Nuclear Information System (INIS)

Tewari, S.K.

1991-01-01

This presentation is aimed at critically reviewing the experiences under several organized efforts to harness wind energy for water lifting for irrigation use in India. This is viewed with the overall objective that wind energy devices should be seen operating in good numbers in farms in a reliable and cost-effective manner. The focus is on irrigation in farms using pumped water, which could generate a fairly large demand for wind pumps. The quantity of pumped water required for irrigation is at least one order of magnitude higher compared to its demand from domestic and industrial uses in urban areas. With respect to the hardware India has a broad experience that goes back to the mid-fifties, when the first classic multi-blades were imported. The tests and experiments, beginning in the early sixties, include a.o. imported classic multi-blades, modified locally produced multi-blades, modern wind pumps without gearbox (12PU500), sail windmills and rotary pumps. A 1983 study showed that in certain regions in India irrigation with wind pumps can be economically more viable than other renewable and conventional alternatives. The conclusions of this study still have to be confirmed by field studies. Although the government shows great interest in the exploitation of the wind energy potential, one of the main problems seems how to get the government interested in the most viable wind energy applications. 1 ill., 1 tab

Comparison of four microfinance markets from the point of view of the effectuation theory, complemented by proposed musketeer principle illustrating forces within village banks

Full Text Available Microfinance services are essential tools of formalization of shadow economics, leveraging immature entrepreneurship with external capital. Given the importance of shadow economics for the social balance of developing countries, the importance of an answer to a question of how microfinance entities come into existence, is rather essential. While decision-taking process leading to entrepreneurship were explained by the effectuation theory developed in the 90’, these explanations were not concerned with the logics of creation of microenterprises in neither developing countries nor microfinance village banks. While the abovementioned theories explain the nascence of companies in environment of developed markets, importance of a focus on emerging markets related to large share of human society of microfinance clientele is obvious. The study provides a development streak to the effectuation Theory, adding the musketeer principle to the five effectuation principles proposed by Sarasvathy. Furthermore, the hitherto not considered relationship between social capital and effectuation related concepts is another proposal of the paper focusing on description of the nature of microfinance clientele from the point of view of effectuation theory and social capital drawing a comparison of microfinance markets in four countries, Turkey, Sierra Leone, Indonesia and Afghanistan.

From Contrapuntal Music to Polyphonic Novel: Aldous Huxley’s Point Counter Point

Directory of Open Access Journals (Sweden)

Mevlüde ZENGİN

2015-06-01

Full Text Available Taken at face value Point Counter Point (1928 written by Aldous Huxley seems to be a novel including many stories of various and sundry people and reflecting their points of view about the world in which they live and about the life they have been leading. However, it is this very quality of the novel that provides grounds for the study of the novel as a polyphonic one. The novel presents to its reader an aggregate of strikingly different characters and thus a broad spectrum of contemporary society. The characters in the novel are all characterized by and individualized with easily recognizable physical, intellectual, emotional, psychological and moral qualities. Each of them is well-contrived through their differences in social status, political views, wealth, etc. Thus, many different viewpoints, conflicting voices, contrasting insights and ideas are heard and seen synchronically in Point Counter Point, which makes it polyphonic. Polyphony is a musical motif referring to different notes and chords played at the same time to create a rhythm. It was first adopted by M. M. Bakhtin to analyze F. M. Dostoyevsky’s fiction. The aim of this study is firstly to elucidate, in Bakhtinian thought, polyphony and then dialogism and heteroglossia closely related to his concept of polyphony; and then to put the polyphonic qualities in Point Counter Point forth, studying the novel’s dialogism and heteroglot qualities

Integration of geophysical datasets by a conjoint probability tomography approach: application to Italian active volcanic areas

Full Text Available We expand the theory of probability tomography to the integration of different geophysical datasets. The aim of the new method is to improve the information quality using a conjoint occurrence probability function addressed to highlight the existence of common sources of anomalies. The new method is tested on gravity, magnetic and self-potential datasets collected in the volcanic area of Mt. Vesuvius (Naples, and on gravity and dipole geoelectrical datasets collected in the volcanic area of Mt. Etna (Sicily. The application demonstrates that, from a probabilistic point of view, the integrated analysis can delineate the signature of some important volcanic targets better than the analysis of the tomographic image of each dataset considered separately.

The team approach to managing dental implant complications: the periodontist's point of view.

Science.gov (United States)

Froum, Stuart J

2013-10-01

Implant-related complications are a fact of life among practitioners who place or restore implants. They occur for a variety of reasons with varying consequences. Those classified as minor complications are most easily corrected and may have little impact on the course of treatment, but severe complications can have serious consequence in expense, complexity, and ultimate success. Many severe complications may be irreversible, leaving the patient with less desirable esthetic options, or worse, permanent disability in terms of speech and function. While various members of the dental team may have different points of view, implant complications are a concern to all. Successful results require comprehensive care, collaborative treatment, and knowledge of dental implant complications. Therefore, it is in the best interest of the patient that all involved in treatment be aware of the different types of complications that can be experienced and learn how to work together as a team to achieve successful outcomes.

The hydrogeologic study covers an area of 50 km{sup 2} with the objectives of to determine the possibility of use of the underground waters and to locate places to carry out exploratory perforations in lands of Cafam, equally the elaboration of a hydrogeologic map of the region; for the effect it was carried out cartography geologic scale 1:10.000, inventory and sampling of water point, geoelectric prospecting and some permeability tests. In the area the exploitation of underground water is incipient, alone there are 20 points of water, of which none produce more than 1L/seg. The water has in general good physical chemistry quality for the human consumption. Geologically was recognized the groups Guadalupe and Gualanday, also some quaternary deposits; the previous ones were subdivided in 11 geological units for its composition and morphology, which are framed structurally in the E flank of the synclinal of Carmen de Apicala and displaced by traverse faults with address E-W and N-W. From the point of hydrogeologic view the units were grouped in 8 aquifer systems, of which four are considered of hydrogeologic importance for the area; the sector with better possibilities to capture these aquifer systems is the W of the area (in the terraces area) that extends to the Sumapaz River. For the Cafam sector a place was selected to build an exploratory well of 200 mts. of depth that would capture an aquifer of low transmissivity, corresponding to the Unit T3.

The problems related to the environment are reported regularly to the public by means of the newspapers, on radio and television. The story is the product of a journalistic process and in general does not bear much resemblance to the original event. The rate and type of reportage depend not only on the body of data available to the journalist but on the information sources the journalist chosen to use. The same story is reported in a positive or negative way. Finally people are overwhelmed by contradictory information and became uncertain or frightened. In order to provide the general public with objective information about nuclear energy in particular and to made a statement about the position of the Belgian Catholic Church concerning this matter, the results of the study were published in Dutch under the form of a book with the title 'The Energy Sources and Nuclear Energy - Comparative analysis and ethical thoughts written the same author.

Analytical approach to determine vertical dynamics of a semi-trailer truck from the point of view of goods protection

Science.gov (United States)

Pidl, Renáta

2018-01-01

The overwhelming majority of intercontinental long-haul transportations of goods are usually carried out on road by semi-trailer trucks. Vibration has a major effect regarding the safety of the transport, the load and the transported goods. This paper deals with the logistics goals from the point of view of vibration and summarizes the methods to predict or measure the vibration load in order to design a proper system. From these methods, the focus of this paper is on the computer simulation of the vibration. An analytical method is presented to calculate the vertical dynamics of a semi-trailer truck containing general viscous damping and exposed to harmonic base excitation. For the purpose of a better understanding, the method will be presented through a simplified four degrees-of-freedom (DOF) half-vehicle model, which neglects the stiffness and damping of the tires, thus the four degrees-of-freedom are the vertical and angular displacements of the truck and the trailer. From the vertical and angular accelerations of the trailer, the vertical acceleration of each point of the platform of the trailer can easily be determined, from which the forces acting on the transported goods are given. As a result of this paper the response of the full platform-load-packaging system to any kind of vehicle, any kind of load and any kind of road condition can be analyzed. The peak acceleration of any point on the platform can be determined by the presented analytical method.

Hamlet - little known piece by Enriko Josif: Literary-theoretical, philosophical and musicological views

2011-01-01

Full Text Available Hamlet is well-known as the most famous tragedy written by William Shakespeare. This dramatic work has, throughout the centuries, lead numerous writers, poets, literary-critics and philosophers to think about universal issues of life, human nature, love, loyalty and friendship. Hamlet has not just been the subject of discussion from the point of view of the theory of literature and human psychology and philosophy, it has also directly inspired the creation of many artistic works. One of those works which forms the main subject-matter of this paper is the almost unknown music for Hamlet by Enriko Josif. Enriko Josif was an extraordinary figure, a versatile artist and thinker, almost a kind of philosopher. In his opinion and in accordance with his inner feeling, art was a matter of divine creation first of all. He admired those artists who dealt with difficult issues of life in their works of art and William Shakespeare was to him one of the most prominent among them. In general terms, we have highlighted certain general points about Josif’s views on an artist’s life and work and have presented our notions about his piece. Specifically, we have tried to point out personal views that Josif held about Hamlet, as well as the most important features of Josif’s music, which are broadly in accordance with the literary, ethical, philosophical and theological critical tradition surrounding this masterpiece.

Extraction of Point Source Gamma Signals from Aerial Survey Data Taken over a Las Vegas Nevada, Residential Area

Thane J. Hendricks

2007-01-01

Detection of point-source gamma signals from aerial measurements is complicated by widely varying terrestrial gamma backgrounds, since these variations frequently resemble signals from point-sources. Spectral stripping techniques have been very useful in separating man-made and natural radiation contributions which exist on Energy Research and Development Administration (ERDA) plant sites and other like facilities. However, these facilities are generally situated in desert areas or otherwise flat terrain with few man-made structures to disturb the natural background. It is of great interest to determine if the stripping technique can be successfully applied in populated areas where numerous man-made disturbances (houses, streets, yards, vehicles, etc.) exist

Full Text Available In this article based upon empiric empirical experimental research, we disclose point of view from students, teachers and parents side. Highlighting school and parents influence to students attitude to education importance. Disclosing different views on education between 10th and 12th grade students. Students view on modern youths values shows that they don’t really care about education (10th grade – 7%, 12th grade – 9%. The most valuable thing is money (10th gr. – 23%, 12th gr. – 32%, and independence (10th gr. – 23%, 12th gr. – 33%. This shows us that material fulfillment, as they think, leads to successful future. So in this case “fast” money and independence becomes a successful life standard. However answer to question what is most important to them personally education is most reachable value (10th gr. – 58%, 12th gr. – 49%. This shows us that youth is not ready (psychologically prepared to open up their true values. In the other hand that shows us lack of openness in our relationship. Personally highest rates goes to education (10th gr. – 58%, 12th gr. – 49%; communication and collaboration (10th gr. – 52%, 12th gr. – 45%, self esteem (10th gr. – 48%, 12th gr. – 49%, honesty (10th gr. – 41%, 12th gr. – 37%. In conclusion we can say that social relationship and collaboration helps to achieve goals, in this case – education. Most of students are looking forward to achieve higher education (10th gr. – 43%, 12th gr. – 46%. Planning to study in Lithuania (10th gr. – 44%, 12th gr. – 50%. Students planning to go for postgraduate studies (10th gr. – 18%, 12th gr. – 25%. This shows us that not only 12th grade students, but also 10th grade students understand higher education importance. It is not a surprise that amount of postgraduate students is growing each year. Achievement of higher education students are linking with opportunity to make more money (10th gr. – 26%, 12th gr. – 32%; getting

As an important innovation of modern management concept, Knowledge Management has been applied in fields as enterprise management and government administration, and has become an important development direction of document management. However, KM currently is still in an embarrassing position in China. As a modern management concept, KM has to exert its function sufficiently by using modern technology. To implement enterprise KM strategy successfully, we need to evaluate enterprise's strategic objectives, organization, system, technology, personnel, capital, work flow, knowledge flow, culture and so on exactly and roundly, to persist in the humanity-based principle, to find out the factors that block the implantation of enterprise KM, to define the objectives of enterprise KM, and accordingly, to formulate corresponding implementation plan and strategy, and to chose appropriate KM tools, etc. From the document management's point of view, KM concept could and should be integrated with digital library and digital archives to construct digital library/digital archives of knowledge management type; to find out the breakthrough of KM and to do the basic jobs of KM well, that includes integrating all kinds of literature resources efficiently, improving the document management level, and constructing different kinds of enterprise knowledge repositories according to user's requirement.

Full Text Available As practice shows us, at the present time ecosystem services are recognized by humanity, but unfortunately are undervalued compared to their full potential. Most of planet's ecosystems are degradated by anthropic activity of humankind. It is almost impossible to say that there are no areas affected by human activity, however, the Protected Areas are a good opportunity, so the assessing of ecosystem services in Protected Areas can be a solution to the problem of economic growth. At present, there are few consistent informations on economic value of ecosystem services in Romania, on the basis of which can be adopted some sustainable financing policies of activities in Protected Areas. The premise from which we start is that a proper management of natural capital will allow biodiversity conservation and human well-being if it find appropriate economic instruments. For this reason, studies of economic research on the contribution of those ecosystem services to the communities welfare may constitute credible means for decision-makers, demonstrating the Protected Areas importance. This paper, based on the study of international and national literature, examines the state of knowledge on the economic and environmental valences of ecosystem services. The growing interest of researchers regarding the economic valuation of ecosystem services related to Protected Areas is visible through the many studies carried out at international level. Although national scientific research relating to ecosystem services is at the beginning, concerns researchers economists and ecologists have been directed toward this recess, of ecosystem services. The reason for we should assign an economic value to ecosystem services is to ensure that their value is included actively in decision-making and is not ignored because "is still available". Briefly, the paper start with an overview of the main definition of ecosystem services. From the point of economic value view, the paper

Full Text Available Sensitivity studies indicate that among the diverse error sources of ground-based sky radiometer observations, the pointing error plays an important role in the correct retrieval of aerosol properties. The accurate pointing is specially critical for the characterization of desert dust aerosol. The present work relies on the analysis of two new measurement procedures (cross and matrix specifically designed for the evaluation of the pointing error in the standard instrument of the Aerosol Robotic Network (AERONET, the Cimel CE-318 Sun photometer. The first part of the analysis contains a preliminary study whose results conclude on the need of a Sun movement correction for an accurate evaluation of the pointing error from both new measurements. Once this correction is applied, both measurements show equivalent results with differences under 0.01° in the pointing error estimations. The second part of the analysis includes the incorporation of the cross procedure in the AERONET routine measurement protocol in order to monitor the pointing error in field instruments. The pointing error was evaluated using the data collected for more than a year, in 7 Sun photometers belonging to AERONET sites. The registered pointing error values were generally smaller than 0.1°, though in some instruments values up to 0.3° have been observed. Moreover, the pointing error analysis shows that this measurement can be useful to detect mechanical problems in the robots or dirtiness in the 4-quadrant detector used to track the Sun. Specifically, these mechanical faults can be detected due to the stable behavior of the values over time and vs. the solar zenith angle. Finally, the matrix procedure can be used to derive the value of the solid view angle of the instruments. The methodology has been implemented and applied for the characterization of 5 Sun photometers. To validate the method, a comparison with solid angles obtained from the vicarious calibration method was

Philip Michalk

2013-12-01

Full Text Available Background: Combined transport chains (such as intermodal transport, have certain advantages. The main advantage from customer points of view is the possibility to bundle freight and thereby decrease transport costs. On the other hand, a combined transport chain can cause longer transport times, due to the necessary transshipment processes. Methods: The area around a terminal, in which a combined service has favourable properties to a customer in comparison to a direct transport, can be understood as a sales-area, in which a combined transport product is marketable. The aim of this paper was to find a method to determine the best shape and size of this area. Results and conclusions: The paper at hand lined out a method in order to calculate such a sales area and determine which geographical points around a terminal have an advantage in comparison to a direct transport service.

Unlike previous correspondence growing approaches our method allows to use the best-first matching principle in the generic multi-view stereo setting with arbitrary number...... of input images. Our experiments show that matching the most promising seeds first provides very robust point cloud reconstructions efficiently with just a single expansion step. A comparison to the current state-of-the-art shows that our method produces reconstructions of similar quality but significantly...

RW Aur A FROM THE X-WIND POINT OF VIEW: GENERAL FEATURES

International Nuclear Information System (INIS)

Liu, Chun-Fan; Shang, Hsien

2012-01-01

In this paper, the RW Aur A microjet is studied from the point of view of X-wind models. The archived Hubble Space Telescope/STIS spectra of the optical forbidden lines [O I], [S II], and [N II] from RW Aur A, taken in Cycle 8 with seven parallel slits along the jet axis, spaced at 0.''07 apart, were analyzed. Images, position-velocity diagrams, and line ratios among the species were constructed, and compared with synthetic observations generated by selected solutions of the X-wind. Prominent features arising in a steady-state X-wind could be identified within the convolved images and position-velocity diagrams, including FWHM and high-velocity peaks on both of the redshifted and blueshifted jets. The well-known asymmetric velocity profiles of the opposite jets were built into the selected models. We discuss model selections within the existing uncertainties of the stellar parameters and inclination angle of the system. In this framework, the mass-loss rates that were inferred to be decreasing along the jet axis in the literature are the results of slowly decreasing excitation conditions and electron density profiles. Despite the apparent asymmetry in the terminal velocities, line intensities and mass-loss rates, the average linear momenta from the opposite sides of the jet are actually balanced. These previously hard-to-explain features of the asymmetric RW Aur A jet system can now be interpreted in a different but self-consistent manner within the X-wind framework.

Quantitative knowledge of the magnitude, extent and trends of the Digital Divide are critical to understand and identify the regions most in need of help, to make rational decisions on how to address the problems and to make cases for executives, funding agencies and politicians. We report on a project (PingER) to measure the Digital Divide from the point of view of Internet performance. The PingER project has been measuring Internet performance since 1995 and with the increased emphasis on measuring and tracking the Digital Divide, it now covers over 700 hosts in over 150 countries that between them contain over 99% of the world's Internet connected population. In this paper we will describe the how PingER works, it deployment, the data analysis, and presentation. We also introduce a new PingER visualization tool (ViPER) that provides a more appealing interactive visualization of the PingER data and also works on mobile PDAs. We will also show results from PingER that illustrate the magnitude, extent and trends for the Digital Divide, and also compare PingER results with some human development and technology indices.

Transmutation of All German Transuranium under Nuclear Phase Out Conditions – Is This Feasible from Neutronic Point of View?

Merk, Bruno; Litskevich, Dzianis

2015-01-01

The German government has decided for the nuclear phase out, but a decision on a strategy for the management of the highly radioactive waste is not defined yet. Partitioning and Transmutation (P&T) could be considered as a technological option for the management of highly radioactive waste, therefore a wide study has been conducted. In the study group objectives for P&T and the boundary conditions of the phase out have been discussed. The fulfillment of the given objectives is analyzed from neutronics point of view using simulations of a molten salt reactor with fast neutron spectrum. It is shown that the efficient transmutation of all existing transuranium isotopes would be possible from neutronic point of view in a time frame of about 60 years. For this task three reactors of a mostly new technology would have to be developed and a twofold life cycle consisting of a transmuter operation and a deep burn phase would be required. A basic insight for the optimization of the time duration of the deep burn phase is given. Further on, a detailed balance of different isotopic inventories is given to allow a deeper understanding of the processes during transmutation in the molten salt fast reactor. The effect of modeling and simulation is investigated based on three different modeling strategies and two different code versions. PMID:26717509

Role & Impact of Interest Rate in Jordan’ Economy from Points of View of Banking Managers

2017-05-01

Full Text Available The research aimed at investigating the role, impact and determinants of interest rate in Jordanian economy from view points of banking managers in Jordan. The methodology is descriptive and analytical using mean, standard deviation, t-test and percentages as statistical tools. The study concluded that the role of interest rate in Jordanian monetary policy is restricted by two factors: pegging JD with US$ which limits the effective role of interest rate in Jordanian monetary policy and the dual banking system of traditional and Islamic banks where Islamic banks do not deal with Interest rate. Raising interest rate in Jordan caused higher cost of credit for companies, less competitiveness of exports, less liquidity in the economy, higher profit margin for banks, higher exchange rate of JD and higher inflation. Nevertheless, lowering interest rate in Jordan caused lower cost of borrowing, higher liquidity, better competitiveness of exports and more credit facilities by banks but inflation was much lower. Moreover, the study concluded the determinants of interest rate in Jordan are money supply, demand for money, inflation and economic conditions. In order to have an effective role for interest rate in monetary policy, the researcher recommends pegging JD to a basket of currencies.

Theoretical points of view on the notion of cause (consideration of contracts in the Serbian doctrine of civil law till the adoption of the law on obligations

Dudaš Atila

2011-01-01

Full Text Available In this paper the author analyzes the different points of view on the notion of cause (consideration in contract in the Serbian doctrine of civil law as until the adoption of the Law on Obligations in 1978. Having in mind that the Law, adhering to the normative solutions of the French Civil Code, explicitly regulates the institution of cause of contract, as one of the conditions of formation and validity of contract, its adoption can certainly be considered as an event of a watershed importance in respect of the analysis of various theoretical points of view on the notion of cause of contract in the Serbian literature. The fact that the institution of cause of contract had not been explicitly regulated in Serbian positive law as until the adoption of Law on Obligations had its effect on the evolution of doctrine in this period in two ways. On one hand, the range of differing theoretical points of view was very wide, covered as good as all the relevant streams in the doctrine of cause, from the ones accepting this institution (so-called causalistic theories to the ones denying its legal significance in any sense (so-called anticausalistic theories. By the adoption of the Law on Obligations in 1978 the notion of cause of contract became a legal institution in Serbian positive law that had a profound impact on the evolution of doctrine. On one hand, the cause of contract was not a neglectable legal notion any more, therefore it seems entirely logical that there is as good as no authority since then who has not dedicated to the notion of cause of contract an article or two, or at least a separate part in their textbooks. On the other hand, the determination of the legislator to assign the Serbian legal system to the family of legal systems in which the notion of cause of contract is stipulated as one of conditions of formation and validity of contract, led to the shrinkage of the diapason of various, often conflicting, points of view on cause of

Atom transistor from the point of view of nonequilibrium dynamics

2015-01-01

We analyze the atom field-effect transistor scheme (Stickney et al 2007 Phys. Rev. A 75 013608) using the standard tools of quantum and classical nonequlilibrium dynamics. We first study the correspondence between the quantum and the mean-field descriptions of this system by computing, both ab initio and by using their mean-field analogs, the deviations from the Eigenstate Thermalization Hypothesis, quantum fluctuations, and the density of states. We find that, as far as the quantities that interest us, the mean-field model can serve as a semi-classical emulator of the quantum system. Then, using the mean-field model, we interpret the point of maximal output signal in our transistor as the onset of ergodicity—the point where the system becomes, in principle, able to attain the thermal values of the former integrals of motion, albeit not being fully thermalized yet.

Full Text Available Collecting silver artefacts has traditionally been a very popular hobby. Silver is addictive, therefore the number of potential collectors and investors appears to grow each year. Unfortunately, increases in the interest and buying potentials resulted in a number of forgeries manufactured and introduced to the open antique market. The items such as early silver candlesticks dictate a very high price, for many high quality fakes show very good appearances and matching similarities with originals. Such copies are traditionally manufactured by casting using the original items as patterns. Small details and variances in design features, position and shape of hallmarks, including the final surface quality are usual features to distinguish the fakes from the originals. This paper presents results of a study conducted on several silver candlesticks, including two artefacts bearing features of those produced in the mid 18th century, one original Italian candelabrum from Fascist era, and small candlesticks made in the early 20th century. Also, the paper presents some interesting contemporary coins ?replicas of many those produced in different countries. The coins were offered for sale by unscrupulous dealers via auctions and e-bays. Finally the main results and findings from this study are discussed from a manufacturing point of view, such as fabrication technology, surface quality and hallmarks, which will help the collectors, dealers and investors to detect and avoid forgeries.

The hydrogeologic study covers an area of 50 km 2 with the objectives of to determine the possibility of use of the underground waters and to locate places to carry out exploratory perforations in lands of Cafam, equally the elaboration of a hydrogeologic map of the region; for the effect it was carried out cartography geologic scale 1:10.000, inventory and sampling of water point, geoelectric prospecting and some permeability tests. In the area the exploitation of underground water is incipient, alone there are 20 points of water, of which none produce more than 1L/seg. The water has in general good physical chemistry quality for the human consumption. Geologically was recognized the groups Guadalupe and Gualanday, also some quaternary deposits; the previous ones were subdivided in 11 geological units for its composition and morphology, which are framed structurally in the E flank of the synclinal of Carmen de Apicala and displaced by traverse faults with address E-W and N-W. From the point of hydrogeologic view the units were grouped in 8 aquifer systems, of which four are considered of hydrogeologic importance for the area; the sector with better possibilities to capture these aquifer systems is the W of the area (in the terraces area) that extends to the Sumapaz River. For the Cafam sector a place was selected to build an exploratory well of 200 mts. of depth that would capture an aquifer of low transmissivity, corresponding to the Unit T3

Urban sprawl is a major driving force that alters local and regional hydrology and increases non-point source pollution. Using the Bao'an District in Shenzhen, China, a typical rapid urbanization area, as the study area and land-use change maps from 1988 to 2014 that were obtained by remote sensing, the contributions of different land-use types to NPS pollutant production were assessed with a localized long-term hydrologic impact assessment (L-THIA) model. The results show that the non-point source pollution load changed significantly both in terms of magnitude and spatial distribution. The loads of chemical oxygen demand, total suspended substances, total nitrogen and total phosphorus were affected by the interactions between event mean concentration and the magnitude of changes in land-use acreages and the spatial distribution. From 1988 to 2014, the loads of chemical oxygen demand, suspended substances and total phosphorus showed clearly increasing trends with rates of 132.48 %, 32.52 % and 38.76 %, respectively, while the load of total nitrogen decreased by 71.52 %. The immigrant population ratio was selected as an indicator to represent the level of rapid urbanization and industrialization in the study area, and a comparison analysis of the indicator with the four non-point source loads demonstrated that the chemical oxygen demand, total phosphorus and total nitrogen loads are linearly related to the immigrant population ratio. The results provide useful information for environmental improvement and city management in the study area.

The Istituto Nazionale di Geofisica e Vulcanologia (INGV) is currently the largest European scientific institution dealing with Earth Sciences research and real-time surveillance, early warning, and forecast activities in geophysics and volcanology. The Laboratorio Didattica e Divulgazione Scientifica of INGV organizes every year educational and outreach activities with schools of different levels and with general public to convey scientific knowledge and to promote the Research on Earth Science, focusing on volcanic and seismic hazard. Among the most successful initiatives is the creation of a calendar designed for the schools and realized based on a competition devoted to children of primary school. The intent is to provide a pleasant stimulus for discussion for teachers and students. Schools participate with enthusiasm by sending drawings made by children on a specified theme, different each year, chosen among geophysics and earth sciences arguments. For 2011, the theme was selected also with the aims to investigate on the image the young generations have of the Research and on its potential and future prospective. The title was "Scienziato anche io! La Scienza e gli scienziati visti dai bambini" (I'm a scientist too! Science and scientists from the children point of view), with the purpose of give a shape to the image children have of the world of science, its potential and the figure of the scientists. We asked the children to realized a draw suggesting some possible arguments between: 1. How do you imagine a scientist? How do you imagine the daily activities of a researcher? 2. What is the invention you consider the most important among all those you know? 3. What would you invent? The 986 drawings realized by 6 up to 10 years old boys and girls from 48 schools distributed throughout the Italian territory, report us a generally positive picture of the work of scientists and also highlight a great level of confidence in the potential of science, capable to

Statistical point of view on nucleus excited states and fluctuations of differential polarization of particles emitted during nuclear reactions

As previous works notably performed by Ericson outlined the fact that the compound nucleus model resulted in variations of efficient cross sections about average values and that these variations were not negligible at all as it had been previously admitted, this research thesis aims at establishing theoretical predictions and at showing that Ericson's predictions can be extended to polarization. After having qualitatively and quantitatively recalled the underlying concepts used in the compound nucleus and direct interaction models, the author shows the relevance of a statistical point of view on nuclei which must not be confused with the statistical model itself. Then, after a recall of results obtained by Ericson, the author reports the study of the fluctuations of differential polarization, addresses the experimental aspect of fluctuations, and shows which are the main factors for this kind of study [fr

The introduction of learning technologies into educational settings continues to grow alongside the emergence of innovative technologies into the healthcare arena. The challenge for health professionals such as medical, nursing, and allied health practitioners is to develop an improved understanding of these technologies and how they may influence practice and contribute to healthcare. For nurse educators to remain contemporary, there is a need to not only embrace current technologies in teaching and learning but to also ensure that students are able to adapt to this changing pedagogy. One recent technological innovation is the use of wearable computing technology, consisting of video recording with the capability of playback analysis. The authors of this article discuss the introduction of the use of wearable Point of View video glasses by a cohort of nursing students in a simulated clinical learning laboratory. Of particular interest was the ease of use of the glasses, also termed the usability of this technology, which is central to its success. Students' reflections were analyzed together with suggestions for future use.

Area burned in tropical savannas of Brazil was mapped using MODIS-AQUA daily 250m resolution imagery by adapting one of the European Space Agency fire_CCI project burned area algorithms, based on change point detection and Markov random fields. The study area covers 1,44 Mkm2 and was performed with data from 2005. The daily 1000 m image quality layer was used for cloud and cloud shadow screening. The algorithm addresses each pixel as a time series and detects changes in the statistical properties of NIR reflectance values, to identify potential burning dates. The first step of the algorithm is robust filtering, to exclude outlier observations, followed by application of the Pruned Exact Linear Time (PELT) change point detection technique. Near-infrared (NIR) spectral reflectance changes between time segments, and post change NIR reflectance values are combined into a fire likelihood score. Change points corresponding to an increase in reflectance are dismissed as potential burn events, as are those occurring outside of a pre-defined fire season. In the last step of the algorithm, monthly burned area probability maps and detection date maps are converted to dichotomous (burned-unburned maps) using Markov random fields, which take into account both spatial and temporal relations in the potential burned area maps. A preliminary assessment of our results is performed by comparison with data from the MODIS 1km active fires and the 500m burned area products, taking into account differences in spatial resolution between the two sensors.

From 2006 to 2013, 12 patients with severe epistaxis refractory to prior conservative and surgical therapy were treated by superselective embolization of nasal arteries. Supersoft platinum microcoils with smallest diameters were used as the sole embolic agent in all cases. Coils were applied far distally in a stretched position for obtaining ideal target vessel superselectivity. The objective of this study is to evaluate efficacy and complications of superselective coil embolization for treatment of severe intractable epistaxis and to discuss results from an otorhinolaryngologic and an interventional neuroradiologic point of view. Retrospectively, all epistaxis inpatients between 2006 and 2013 were identified and subdivided by form of treatment: conservative, surgical and interventional therapy. Medical records of interventionally treated patients were reviewed for demographics, medical history, risk factors, clinical data, complications and short-term success, and patients were followed up for long-term success. Mean follow-up was 37 months. In 12 patients, 14 embolizations were carried out, with short-term success in 9 patients (75%), while early post-interventional rebleeding occurred in 3 patients (25%). Of 9 patients with short-term success, 1 died during stay, 1 was lost to follow-up and 1 had minor re-bleeding after 30 months. Six patients had short-term and long-term success. Before the first embolization, 3 ± 1 conservative and/or surgical procedures had been undertaken. Length of stay was 12.8 ± 3.6 days. 8 patients (67%) received red cell concentrates. Most frequent complications were mucosal damage and nasal pain, but these were related to repeated packing and surgery. Typical embolic complications as neurological or visual impairment or soft tissue necrosis were not observed in any patient. From the otorhinolaryngologic point of view, surgery is the treatment of choice in severe refractory epistaxis, but in case of repeated failure, superselective

The problem of obtaining the self-consistent areas law in quantum chromodynamics (QCD) is considered from the point of view of the quark confinement. The exact equation for the loop average in multicolor QCD is reduced to a bootstrap form. Its iterations yield new manifestly gauge invariant perturbation theory in the loop space, reproducing asymptotic freedom. For large loops, the areas law apprears to be a self-consistent solution

Purpose: Intensity modulated radiotherapy (IMRT) and volumetric modulated arc therapy have become standard treatments but are more sensitive to anatomical variations than 3D conformal techniques. To correct for inter- and intrafraction anatomical variations, fast and easy to implement methods are needed. Here, the authors propose a full dosimetric IMRT correction that finds a compromise in-between basic repositioning (the current clinical practice) and full replanning. It simplifies replanning by avoiding a recontouring step and a full dose calculation. It surpasses repositioning by updating the preoptimized fluence and monitor units (MU) using a limited number of fiducial points and a pretreatment (CB)CT. To adapt the fluence the fiducial points were projected in the beam's eye view (BEV). To adapt the MUs, point dose calculation towards the same fiducial points were performed. The proposed method is intrinsically fast and robust, and simple to understand for operators, because of the use of only four fiducial points and the beam data based point dose calculations. Methods: To perform our dosimetric adaptation, two fluence corrections in the BEV are combined with two MU correction steps along the beam's path. (1) A transformation of the fluence map such that it is realigned with the current target geometry. (2) A correction for an unintended scaling of the penumbra margin when the treatment beams scale to the current target size. (3) A correction for the target depth relative to the body contour and (4) a correction for the target distance to the source. The impact of the correction strategy and its individual components was evaluated by simulations on a virtual prostate phantom. This heterogeneous reference phantom was systematically subjected to population based prostate transformations to simulate interfraction variations. Additionally, a patient example illustrated the clinical practice. The correction strategy was evaluated using both dosimetric

Because of the location of the Bowline, Roseton, and Indian Point power generating facilities in the low-salinity zone of the Hudson estuary, operation of these plants with the present once-through cooling systems will adversely influence the fish populations that use the area for spawning and initial periods of growth and development. Recruitment rates and standing crops of several fish species may be lowered in response to the increased mortality caused by entrainment of nonscreenable eggs and larvae and by impingement of screenable young of the year. Entrainment and impingement data are particularly relevant for assessing which fish species have the greatest potential for being adversely affected by operation of Bowline, Roseton, and Indian Point with once-through cooling. These data from each of these three plants suggest that the six species that merit the greatest consideration are striped bass, white perch, tomcod, alewife, blueback herring, and bay anchovy. Two points of view are available for assessing the relative importance of the fish species in the Hudson River. From the fisheries point of view, the only two species of major importance are striped bass and shad. From the fish-community and ecosystem point of view, the dominant species, as determined by seasonal and regional standing crops (in numbers and biomass per hectare), are the six species most commonly entrained and impinged, namely, striped bass, white perch, tomcod, alewife, blueback herring, and anchovy

2018-01-01

In studies involving the extraction of surface physical parameters using optical remote sensing satellite imagery, sun-sensor geometry must be known, especially for sensor viewing angles. However, while pixel-by-pixel acquisitions of sensor viewing angles are of critical importance to many studies, currently available algorithms for calculating sensor-viewing angles focus only on the center-point pixel or are complicated and are not well known. Thus, this study aims to provide a simple and ge...

Timely identification of areas affected by natural disasters is very important for a successful rescue and effective emergency relief efforts. This research focuses on the development of a cost effective and efficient system of identifying areas affected by natural disasters, and the efficient distribution of the information. The developed system is composed of 3 modules which are the Web Processing Service (WPS), Web Map Service (WMS) and the user interface provided by J-iView (fig. 1). WPS is an online system that provides computation, storage and data access services. In this study, the WPS module provides online access of the software implementing the developed frequency based change detection algorithm for the identification of areas affected by natural disasters. It also sends requests to WMS servers to get the remotely sensed data to be used in the computation. WMS is a standard protocol that provides a simple HTTP interface for requesting geo-registered map images from one or more geospatial databases. In this research, the WMS component provides remote access of the satellite images which are used as inputs for land cover change detection. The user interface in this system is provided by J-iView, which is an online mapping system developed at the Geological Survey of Japan (GSJ). The 3 modules are seamlessly integrated into a single package using J-iView, which could rapidly generate a map of disaster areas that is instantaneously viewable online. The developed system was tested using ASTER images covering the areas damaged by the March 11, 2011 tsunami in northeastern Japan. The developed system efficiently generated a map showing areas devastated by the tsunami. Based on the initial results of the study, the developed system proved to be a useful tool for emergency workers to quickly identify areas affected by natural disasters.

Establishing supervisor-students’ relationships through mutual expectation: A study from supervisors’ point of view

Science.gov (United States)

Masek, Alias

2017-08-01

The literature suggests that failure to establish a good relationship in communicating expectations of research supervision is one of the factors contributing to the slow pace of research progress. Moreover, it is not fully understood how students and a supervisor ‘pre-define’ their styles and communicate their expectations through a successful relationship. As a result, the students might lose motivation to do their research during the study period and are not able to complete their research on time. This will subsequently entail an extension of the study period. Without a good relationship between students and the supervisor, miscommunication occurs, leading to mismatched expectations from both parties. This research attempts to explore the establishment of a good supervisor-students’ relationship from supervisor point of views, so that supervision expectations can be clearly delivered and effectively communicated; guidelines will be drawn up for forging the supervisor-students’ relationship basing on mutual expectations of both parties.

Mechanistic spatio-temporal point process models for marked point processes, with a view to forest stand data

Møller, Jesper; Ghorbani, Mohammad; Rubak, Ege Holger

We show how a spatial point process, where to each point there is associated a random quantitative mark, can be identified with a spatio-temporal point process specified by a conditional intensity function. For instance, the points can be tree locations, the marks can express the size of trees......, and the conditional intensity function can describe the distribution of a tree (i.e., its location and size) conditionally on the larger trees. This enable us to construct parametric statistical models which are easily interpretable and where likelihood-based inference is tractable. In particular, we consider maximum...

Significance of lenticular opacity from the view point of the exposure dose of A-bomb radiation

Energy Technology Data Exchange (ETDEWEB)

Sugimoto, S [Sugimoto Hospital, Hiroshima (Japan)

1975-04-01

Two cases of lenticular opacity were discussed from the view point of exposure dose of A-bomb radiation. Case 1: female, 22 year and 5 months old when she was exposured to A-bomb radiation. The presumed exposure dose was 482.0 rad. Cataract due to A-bomb radiation. Case 2: female, 21 years and 6 months old when she was exposured to A-bomb radiation. The presumed exposure dose was more than 1,000 rad. Cataract due to A-bomb radiation and incipient cataract senilis. It was reported here that there was a marked difference in opacity findings of cataract due to A-bomb radiation in accordance with difference in exposure dose of radiation. It was also presumed from the findings of incipient cataract senilis that with increasing exposure dose, the aging phenomenon was promoted.

The assessment and prioritisation of research activity are essential components of any Science, Technology and Industry System. Data on researchers' perspectives in this respect are scarce. The objective of this paper was to describe Spanish scientists' point of view on the current evaluation system in Spain and how they believe this system should be functionally structured. From the sampling frame formed by established Spanish scientists, listed in the databases of CSIC and FIS (Institute of Health Carlos III), clinical, biomedical-non clinical, and physics and chemical researchers were randomly selected. Two hundred and eleven interviews were carried out by means of a computer-assisted telephone interviewing system. Researchers expressed their acknowledgement of progress in the Spanish research field but made their wish clear to progress towards better scientific scenarios. In their assessment, they gave a score of 5.4 to scientific policy, as opposed to 9.4 when speaking about the goals, reflecting the desire for a better policy definition, with clear objectives, stable strategies and better coordination of R&D activities (the current coordination received a score of 3.9, while the desirable coordination was valued as high as 9.2). There was certain agreement regarding the need for a prioritisation criteria which preserves some degree of creativity by researchers. They also stated that they would like to see an independent research structure with social prestige and influence. The interviewed researchers believe that the evaluation of scientific activities is fundamental in formulating a sound scientific policy. Prioritisation should arise from appropriate evaluation. Strategies properly coordinated among all the stakeholders (including the private sector) should be fostered. Budget sufficiency, stability, and better organization of independent researchers should be the backbone of any strategy tailored to increase their capacity to influence future scientific

Full Text Available Construction is one of the highest contributing industries to occupational accidents by sector in Malaysia. Statistics have been drawn from year to year that show an increasing number of cases of accidents by industry sector. While it is impossible to completely eliminate all accidents, with a proper and effective safety and health policy or rules set by top management, especially contractors, the rate of accidents on construction sites can be reduced. The main objective of this study is to analyse the degree of application of the Occupational Safety and Health Act 1994 (OSHA 1994 in the construction industry and to identify the contributing factors leading to a lack of execution of OSHA 1994 on construction sites with a primary focus on contractors’ point of view. Five on-going construction projects in Perak were selected as case studies and site inspections were conducted. The results showed that none of the contractors have fully implemented the rules and regulations provided by the government. Within this report, some recommendations are made towards enhancing the safety and health issues on construction sites.

Data analysis strategies for the characterization of normal: superconductor point contacts by barrier strength parameter

Smith, Charles W.; Reinertson, Randal C.; Dolan, P. J., Jr.

1993-05-01

The theoretical description by Blonder, Tinkham, and Klapwijk [Phys. Rev. B 25, 4515 (1982)] of the I-V curves of normal: superconductor point contacts encompasses a broad range of experimental behavior, from the tunnel junction case, on the one hand, to the clean metallic microconstriction limit on the other. The theory characterizes point contacts in terms of a single parameter, the barrier strength. The differential conductance of a point contact, at zero bias, as a function of temperature, offers a direct experimental method by which the barrier strength parameter can be evaluated. In view of the full range of phenomena incorporated by this theory, we suggest several different strategies for the evaluation of the barrier strength parameter from data in the low and intermediate barrier strength regimes and for measurements in the low temperature (near T=0 K) and high temperature (near T=Tc) limits.

Research of the Rock Art from the point of view of geography: the neolithic painting of the Mediterranean area of the Iberian Peninsula

Full Text Available The rock art of the Mediterranean Arch (which includes what are conventionally called Levantine Rock Art, Schematic Rock Art and Macroschematic Rock Art, among other styles, designated as part of the Human Heritage in 1997, is studied from the point of view of the Archaeology of Landscape. The information sources used were field work, cartographic analysis and analysis in GIS, besides two Rock Art Archives: the UNESCO Document and the Corpus of Levantine Cave Painting (Corpus de Pintura Rupestre Levantina. The initial hypothesis was that this rock art was involved in the process of neolithisation of the Eastern part of Iberia, of which it is a symptom and a result, and it must be understood as an element of landscape construction. If this is true, it would have a concrete distribution in the form of locational patterns. Through statistical procedures and heuristical approaches, it has been demonstrated that there is a structure of the neolithic landscape, defined by rock art, which is possible to interpret functional and economically.

Se estudia el arte rupestre del Arco Mediterráneo (que incluye a los convencionalmente conocidos como Arte Levantino, Arte Esquemático y Arte Macroesquemático, entre otros estilos, nombrado Patrimonio de la Humanidad en 1998, desde el punto de vista de su localización. Las fuentes de información utilizadas fueron trabajo de campo, revisión cartográfica y análisis en Sistema de Información Geográfica, además de dos archivos de arte rupestre: el Expediente UNESCO y el Corpus de Pintura Rupestre Levantina. La hipótesis inicial fue que este arte rupestre se imbrica en el proceso de neolitización del Levante peninsular, del que es síntoma y resultado, y debe entenderse como un elemento de construcción paisajística, de lo que se deduce que ha de presentar una distribución determinable en forma de patrones locacionales.

Immunity & Ageing: a new journal looking at ageing from an immunological point of view

Directory of Open Access Journals (Sweden)

Caruso Calogero

2004-10-01

Full Text Available Abstract In the elderly, many alterations of both innate and clonotypic immunity have been described. Alterations to the immune system in the elderly are generally viewed as a deterioration of immunity, leading to the use of the term immunosenescence. However, although many immunological parameters are often notably reduced in the elderly, retained function of both innate and clonotypic immunity in the elderly is tightly correlated to health status. Recognising the important role of the immune system in ageing, over the last few years, journals oriented towards gerontology and geriatric sciences have increasingly published articles dealing with the immunology of ageing, but a specialised journal in this area does not exist. Immunity & Ageing is a new Open Access, peer reviewed journal that aims to cover all the topics dealing with innate and clonotypic immunity which are relevant to ageing. The journal will provide an opportunity to focus on this topic, which is emerging as one of the critical mechanisms of ageing. Furthermore, as an online, Open Access journal, Immunity & Ageing will promote immediate accessibility to research, which is generally not possible for articles published in printed journals. We hope this forum, concentrating on the themes of ageing and immunology with a strong focus on human studies, will create a new perspective for viewing a world that is inevitably becoming older.

Most studies addressing the specificity of meridians and acupuncture points have focused mainly on the different neural effects of acupuncture at different points in healthy individuals. This study examined the effects of acupuncture on brain function in a pathological context. Sixteen patients with ischemic stroke were randomly assigned to true point group (true acupuncture at right Waiguan (SJ5)) and sham point group (sham acupuncture). Results of functional magnetic resonance imaging revealed activation in right parietal lobe (Brodmann areas 7 and 19), the right temporal lobe (Brodmann area 39), the right limbic lobe (Brodmann area 23) and bilateral occipital lobes (Brodmann area 18). Furthermore, inhibition of bilateral frontal lobes (Brodmann area 4, 6, and 45), right parietal lobe (Brodmann areas 1 and 5) and left temporal lobe (Brodmann area 21) were observed in the true point group. Activation in the precuneus of right parietal lobe (Brodmann area 7) and inhibition of the left superior frontal gyrus (Brodmann area 10) was observed in the sham group. Compared with sham acupuncture, acupuncture at Waiguan in stroke patients inhibited Brodmann area 5 on the healthy side. Results indicated that the altered specificity of sensation-associated cortex (Brodmann area 5) is possibly associated with a central mechanism of acupuncture at Waiguan for stroke patients.

Bouma, J.W.J.

1993-01-01

The European gas distribution industry will be faced with real challenges during the coming ten years. Additional import of natural gas from non-European Community countries will be required in view of the growing demand and the concomitant decrease in gas production in the European Community. This implies that facilities for the long-distance transport of gas will have to be built and that considerable investments are required. It is argued that the recommendation for the liberalization of the gas market by the Commission of the European Communities is unsuited to face future developments of the European gas market. (A.S.)

Laser diagnostic and therapy of dental caries: the clinic point of view

Dental caries's diagnosis is a major dentistry problem from the clinic point of view. The laser beam on the region of 655 nm induces the fluorescence of the compounds present in the hard tissue, quantifying differences between sound and carious enamel and dentine. Diagnodent (Kavo, Germany), showed to be effective regarding dental caries's diagnosis in the present research sampling. The Er:YAG laser (Kavo Key Laser 2, Germany) performed efficient cavity preparations in caries lesions of I and V class type, using up energies that ranged from 300 mJ to 350 mJ with 4 Hz repetition rate for the enamel; and from 250 mJ to 300 mJ with 4 Hz repetition rate for the dentine, and with 80 mJ with 6 Hz of repetition rate for laser conditioning. In the Er:YAG laser preparations no patient was anesthetized even when there were deeper cavities, and the maximum degree of pain ( which ranged from 0 to 10) was 4. In the control group with conventional high-speed drill two patients were anesthetized and the maximum degree of pain was 7. Restorations performed by conventional method of composite were equally satisfying both in caries groups of I and V class type and in the control group. The laser application in the operative dentistry office as a new method of diagnosis and dental preparations should be a good alternative to the use of the conventional dental drill. Nevertheless, dentistry practice has a lot to improve from technology progress, as well as new researches on laser dentistry are necessary in a long term. New types of lasers will come about and will increasingly improve the dental practice assistance and procedures quality. (author)

In this paper, we discuss a new methodology based on lensfree imaging to perform wound healing assay with unprecedented statistics. Our video lensfree microscopy setup is a simple device featuring only a CMOS sensor and a semi coherent illumination system. Yet it is a powerful mean for the real-time monitoring of cultivated cells. It presents several key advantages, e.g. integration into standard incubator, compatibility with standard cell culture protocol, simplicity and ease of use. It can perform the follow-up in a large field of view (25 mm(2)) of several crucial parameters during the culture of cells i.e. their motility, their proliferation rate or their death. Consequently the setup can gather large statistics both in space and time. Here we uses this facility in the context of wound healing assay to perform label-free measurements of the velocities of the fronts of proliferation of the cell layer as a function of time by means of particle image velocimetry (PIV) processing. However, for such tissue growth experiments, the field of view of 25 mm(2) remains not sufficient and results can be biased depending on the position of the device with respect to the recipient of the cell culture. Hence, to conduct exhaustive wound healing assays, we propose to enlarge the field of view up to 10 cm(2) through a raster scan, by moving the source/sensor with respect to the Petri dish. We have performed acquisitions of wound healing assay (keratinocytes HaCaT) both in real-time (25 mm(2)) and in final point (10 cm(2)) to assess the combination of velocimetry measurements and final point wide field imaging. In the future, we aim at combining directly our extended field of view acquisitions (>10 cm(2)) with real time ability inside the incubator.

A Novel Approach to Study Medical Decision Making in the Clinical Setting: The "Own-point-of-view" Perspective.

Science.gov (United States)

Pelaccia, Thierry; Tardif, Jacques; Triby, Emmanuel; Charlin, Bernard

2017-07-01

Making diagnostic and therapeutic decisions is a critical activity among physicians. It relies on the ability of physicians to use cognitive processes and specific knowledge in the context of a clinical reasoning. This ability is a core competency in physicians, especially in the field of emergency medicine where the rate of diagnostic errors is high. Studies that explore medical decision making in an authentic setting are increasing significantly. They are based on the use of qualitative methods that are applied at two separate times: 1) a video recording of the subject's actual activity in an authentic setting and 2) an interview with the subject, supported by the video recording. Traditionally, activity is recorded from an "external perspective"; i.e., a camera is positioned in the room in which the consultation takes place. This approach has many limits, both technical and with respect to the validity of the data collected. The article aims at 1) describing how decision making is currently being studied, especially from a qualitative standpoint, and the reasons why new methods are needed, and 2) reporting how we used an original, innovative approach to study decision making in the field of emergency medicine and findings from these studies to guide further the use of this method. The method consists in recording the subject's activity from his own point of view, by fixing a microcamera on his temple or the branch of his glasses. An interview is then held on the basis of this recording, so that the subject being interviewed can relive the situation, to facilitate the explanation of his reasoning with respect to his decisions and actions. We describe how this method has been used successfully in investigating medical decision making in emergency medicine. We provide details on how to use it optimally, taking into account the constraints associated with the practice of emergency medicine and the benefits in the study of clinical reasoning.

Full Text Available This paper present and discussed the results of the monitoring of the dew point values, recorded in October and November 2014, in an ecological station in the Leaota Mountains. In this station, two polls were located in areas covered by colluvial mesovoid shallow substratum (MSS formed by epi- and mesometamorphic crystalline schists. In the ecological stations we located in the Leaota Mountains, almost always we found condensation on the walls of the polls tubes placed at different depths. Most often in spring or autumn or in other cold days, the dew point is more revealing regarding the recording actual amount of moisture in the air, than the relative humidity indicator. This work is part of a larger project that seeks correlations between ecological factors (humidity, temperature and dew point registered in various types of screes (limestone and crystalline schists and some zoocenotic components (invertebrates. This research aim to know the importance of mesovoid shallow substratum for invertebrates or small vertebrates fauna and represents a premiere for Leaota Mountains, not only regarding the continuous monitoring of some ecologic factors of these types of ecosystems (MSS, rarely researched even at global level, and also regarding the inventory of the invertebrate fauna in scree for these mountains.

Superimposition has been used as a method to evaluate the changes of orthodontic or orthopedic treatment in the dental field. With the introduction of cone beam CT (CBCT), evaluating 3 dimensional changes after treatment became possible by superimposition. 4 point plane orientation is one of the simplest ways to achieve superimposition of 3 dimensional images. To find factors influencing superimposition error of cephalometric landmarks by 4 point plane orientation method and to evaluate the reproducibility of cephalometric landmarks for analyzing superimposition error, 20 patients were analyzed who had normal skeletal and occlusal relationship and took CBCT for diagnosis of temporomandibular disorder. The nasion, sella turcica, basion and midpoint between the left and the right most posterior point of the lesser wing of sphenoidal bone were used to define a three-dimensional (3D) anatomical reference co-ordinate system. Another 15 reference cephalometric points were also determined three times in the same image. Reorientation error of each landmark could be explained substantially (23%) by linear regression model, which consists of 3 factors describing position of each landmark towards reference axes and locating error. 4 point plane orientation system may produce an amount of reorientation error that may vary according to the perpendicular distance between the landmark and the x-axis; the reorientation error also increases as the locating error and shift of reference axes viewed from each landmark increases. Therefore, in order to reduce the reorientation error, accuracy of all landmarks including the reference points is important. Construction of the regression model using reference points of greater precision is required for the clinical application of this model.

Background: In-service training courses are one of the most available programs that are used to improve the quantity and quality level of the staff services in various organizations, including libraries and information centers. With the advent of new technologies in the field of education, the problems and shortcomings of traditional in-service training courses were replaced with virtual ones. This study aimed to evaluate the virtual in-service training courses from the librarians' point of view in libraries of state universities of medical sciences in Tehran. Methods: This was a descriptive- analytical study. The statistical population consisted of all librarians at libraries of universities of medical sciences in Tehran. Out of 103 librarians working in the libraries under the study, 93 (90%) participated in this study. Data were collected, using a questionnaire. Results: The results revealed that 94/6% of librarians were satisfied to participate in virtual in-service training courses. In this study, only 45 out of 93 participants said that the virtual in-service courses were held in their libraries. Of the participants, 75.6% were satisfied with the length of training courses, and one month seemed to be adequate time duration for the librarians to be more satisfied. The satisfaction level of the individuals who participated in in-service courses of the National Library was moderate to high. A total of 84.4% participants announced that the productivity level of the training courses was moderate to high. The most important problem with which the librarians were confronted in virtual in-service training was the "low speed of the internet and inadequate computer substructures". Conclusion: Effectiveness of in-service training courses from librarians’ point of view was at an optimal level in the studied libraries. PMID:28491833

The neural correlates of action recognition have been widely studied in visual and sensorimotor areas of the human brain. However, the role of neuronal oscillations involved during the process of action recognition remains unclear. Here, we were interested in how the plausibility of an action modulates neuronal oscillations in visual and sensorimotor areas. Subjects viewed point-light displays (PLDs) of biomechanically plausible and implausible versions of the same actions. Using magnetoencephalography (MEG), we examined dynamic changes of oscillatory activity during these action recognition processes. While both actions elicited oscillatory activity in visual and sensorimotor areas in several frequency bands, a significant difference was confined to the beta-band (∼20 Hz). An increase of power for plausible actions was observed in left temporal, parieto-occipital and sensorimotor areas of the brain, in the beta-band in successive order between 1650 and 2650 msec. These distinct spatio-temporal beta-band profiles suggest that the action recognition process is modulated by the degree of biomechanical plausibility of the action, and that spectral power in the beta-band may provide a functional interaction between visual and sensorimotor areas in humans.

A holographic optical element transforms a spectral distribution of light to image points. The element comprises areas, each of which acts as a separate lens to image the light incident in its area to an image point. Each area contains the recorded hologram of a point source object. The image points can be made to lie in a line in the same focal plane so as to align with a linear array detector. A version of the element has been developed that has concentric equal areas to match the circular fringe pattern of a Fabry-Perot interferometer. The element has high transmission efficiency, and when coupled with high quantum efficiency solid state detectors, provides an efficient photon-collecting detection system. The element may be used as part of the detection system in a direct detection Doppler lidar system or multiple field of view lidar system.

The World Health Organization and the Pharmaceutical Industry. Common areas of interest and differing views.

Hardwicke, Caroline J

2002-01-01

No article published in the scientific press in the last 10 years reviews the various areas of interest common to the World Health Organization (WHO) and the pharmaceutical industry. Despite a vast amount of information in the public domain, the policies expound the views only of the bodies they represent rather than comparing differing views. An understanding of the factors which affect the interaction between these organisations as well as the organisational structures and the actual areas of intersecting interest, may help to find ways for the industry to assist the WHO in its endeavours in developing countries. Modern drug development is performed initially in and for western society, leaving the areas of infectious or tropical diseases with relatively less industry investment than cancer and cardiovascular disorders. Aspects of the development of an ethical drug, regardless of its therapeutic class (selection of drug name, intellectual property rights, drug safety, marketing and pricing, quality assurance and counterfeiting, generic use, emerging drug donations) are influenced to varying degrees by the triad of money, politics and medical need and the perspectives (each defensible) placed thereon by the WHO and industry. Instead of simply defending their positions combining the best of these strategies to optimise drug development for the needs of developing countries appears logical. Similarly, via its philanthropic initiatives, industry will have donated over $US1 billion in drug and research aid in the period 1995 to 2005. These charitable projects should yield useful information for planning and organising future aid efforts. Global warming, only recently given serious governmental consideration, is an area not yet addressed in drug development policy although along with geographical effects, it is likely to have an impact on the epidemiology of diseases e.g. malaria returning to the Mediterranean, worldwide. With changing disease patterns (and

1. A ski-boot should have an adequate arch support and a variable, as well as an exact fitting of the dorsal part. This can be achieved with flow, foam, air or wax. 2. Isolated pressure of compression systems of different kinds should be avoided (e.g. pressure of buckles above the ankle). New results are demonstrated by the possibility of putting on the boot from behind and having the buckles at the back of the boot. 3. The strap from ankle to foot has to be continuous to avoid pressure points. 4. It should be possible to walk and stand in a ski-boot without either muscular strain or pressure on the knee-joint. In addition, the sole has to give an optimal grip also on icy ground to prevent slipping.

Xiao-jiang, with a basin area of almost 5,276 km(2) and a length of 182.4 km, is located in the center of the Three Gorges Reservoir Area, and is the largest tributary of the central section in Three Gorges Reservoir Area, farmland accounts for a large proportion of Xiao-jiang watershed, and the hilly cropland of purple soil is much of the farmland of the watershed. After the second phase of water storage in the Three Gorges Reservoir, the majority of sub-rivers in the reservoir area experienced eutrophication phenomenon frequently, and non-point source (NPS) pollution has become an important source of pollution in Xiao-jiang Watershed. Because dissolved nitrogen and phosphorus non-point source pollution are related to surface runoff and interflow, using climatic, topographic and land cover data from the internet and research institutes, the Semi-Distributed Land-use Runoff Process (SLURP) hydrological model was introduced to simulate the complete hydrological cycle of the Xiao-jiang Watershed. Based on the SLURP distributed hydrological model, non-point source pollution annual output load models of land use and rural residents were respectively established. Therefore, using GIS technology, considering the losses of dissolved nitrogen and phosphorus in the course of transport, a dissolved non-point source pollution load dynamic model was established by the organic coupling of the SLURP hydrological model and land-use output model. Through the above dynamic model, the annual dissolved non-point source nitrogen and phosphorus pollution output as well as the load in different types were simulated and quantitatively estimated from 2001 to 2008, furthermore, the loads of Xiao-jiang Watershed were calculated and expressed by temporal and spatial distribution in the Three Gorges Reservoir Area. The simulation results show that: the temporal changes of dissolved nitrogen and phosphorus load in the watershed are close to the inter-annual changes of rainfall runoff, and the

This work analyzes the potentiality of WorldView-2 satellite data for retrieving the Leaf Area Index (LAI) area located in Apulia, the most Eastern region of Italy, overlooking the Adriatic and Ionian seas. Lacking contemporary in-situ measurements, the semi-empiric method of Clevers (1989) (CLAIR model) was chosen as a feasible image-based LAI retrieval method, which is based on an inverse exponential relationship between the LAI and the WDVI (Weighted Difference Vegetation Index) with relation to different land covers. Results were examined in homogeneous land cover classes and compared with values obtained in recent literature.

The extended Kalman filter (EKF) has been animportant tool for state estimation of nonlinear systems sinceits introduction. However, the EKF does not possess the same optimality properties as the Kalman filter, and may perform poorly. By viewing the EKF as an optimization problem it is possible to, in many cases, improve its performance and robustness. The paper derives three variations of the EKF by applying different optimisation algorithms to the EKF costfunction and relate these to the it...

The educator's point of view.

Dengo De Vargas, M E

Education is considered as an important means of promoting social change, and within this context how population issues can be integrated into development planning and educational practices is discussed. Education is expected to have an impact in future years, and is a necessary means of creating awareness of population-related problems; education for all is a human right. New approaches to population education must include teacher training and creation of awareness about population issues that respect cultural identity and free choice and do not influence customs and values that would run counter to the society. Educators have an ethical responsibility to address issues of population and human life; when seeking outside expertise, the nation should not be "carried away by the pressures of financial agencies which respond to foreign interests." For instance, the psychosocial dynamics and practice of sexual intercourse in Central America are different from those in North America or Europe. Sexual education must be based on sound scientific approaches, but must also include ethical values. Population education must use a holistic, intersectoral approach. Nations have human, natural, and economic resources, which must have a balanced influence. Human development involves being both the object and planner of development. Pope John Paul II noted that development must include the biological, the psychosocial, and the spiritual and reach all men. Human rights must be guaranteed. In addition to equality for women everyone has the right to dignity, education, employment, health, housing, and leisure. Quality of life is a part of human development, and is achieved through a balance between man, his environment, and resources, and liberty and peace. Educational strategies involve macro planning for placement and number of schools and teachers, and decentralizing educational services in order to reach rural areas. Formal and informal education is required. Adult education is

Point-of-sale (POS) is increasingly being used as a marketing tool for alcohol products, and there is a growing body of evidence suggesting that these materials are positively associated with drinking and contribute to creating a pro-alcohol environment. The purpose of the present study was to document the nature and extent of POS alcohol promotions in bottle shops in two Australian capital cities. A purposive sample of 24 hotel bottle shops and liquor stores was selected across Sydney (New South Wales) and Perth (Western Australia) and audited for the presence and nature of POS marketing. Point-of-sale promotions were found to be ubiquitous, with an average of 33 promotions per outlet. Just over half were classified as 'non-price' promotions (e.g. giveaways and competitions). Spirits were the most commonly promoted type of alcohol. The average number of standard drinks required to participate in the promotions ranged from 12 for ready to drinks to 22 for beer. Alcohol outlets that were part of supermarket chains had a higher number of promotions, more price-based promotions, and required a greater quantity of alcohol to be purchased to participate in the promotion. The data collected in this study provides a starting point for our understanding of POS promotions in Australia, and poses important questions for future research in this area. © 2012 Australasian Professional Society on Alcohol and other Drugs.

Honey bee: a consumer’s point of view

Directory of Open Access Journals (Sweden)

Zavodna Lucie Sara

2016-09-01

Full Text Available This article concerns the way bee products are perceived by customers. It is mainly focused on honey, which is considered the main output product of beekeeping. Beekeeping is a very popular activity in the Czech Republic. Based on current data there are over 48 thousand people engaged in beekeeping in the Czech Republic. Hand in hand with the increasing number of beekeepers the popularity of bee products - especially honey - among Czech consumers is also growing. Recently, the consumption of honey in the Czech Republic has been slightly increasing. A big problem today is that honey sold in Czech supermarkets is frequently falsified. At the same time, it is increasingly popular to buy honey directly from beekeepers. The aim of this research was to describe the situation about the honey market in the Czech Republic, and also to examine the relationship between consumers on the one hand, and honey/beekeepers on the other. We have also considered customer's trust in organic honey and honey sold in supermarket chains. Results show that consumers view bee products as generally healthy and prefer to buy bee products from a beekeeper because of greater convenience as locally sourced honey is perceived to be of higher quality. The majority of consumers agree with paying a higher price for a product of higher quality. The article confirmed the hypothesis that most people think that bee products sold by a beekeeper are healthier than those bought at ordinary shops.

Developing the environment-friendly insulation gases to replace sulfur hexafluoride (SF 6 ) has attracted considerable experimental and theoretical attentions but without success. A computational methodology was presented herein for prediction on dielectric strength and boiling point of arbitrary gaseous molecules in the purpose of molecular design and screening. New structure-activity relationship (SAR) models have been established by combining the density-dependent properties of the electrostatic potential surface, including surface area and the statistical variance of the surface potentials, with the molecular properties including polarizability, electronegativity, and hardness. All the descriptors in the SAR models were calculated using density functional theory. The substitution effect of SF 6 by various functional groups was studied systematically. It was found that CF 3 is the most effective functional group to improve the dielectric strength due to the large surface area and polarizability. However, all the substitutes exhibit higher boiling points than SF 6 because the molecular hardness decreases. The balance between E r and T b could be achieved by minimizing the local polarity of the molecules. SF 5 CN and SF 5 CFO were found to be the potent candidates to replace SF 6 in view of their large dielectric strengths and low boiling points. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

2010-01-01

Full Text Available In modern societies gender gap attracts significant attention. Scientists are trying to research this issue from different aspects: demographical, sociological, economic, etc. The goal of this paper is to define the basic variables that explain variation on the labor markets in Europe from the gender point of view and to compare labor market in Serbia with European countries in order to identify the countries with the most similar gender performances, with intention to overview their experiences concerning the policy measures for gender gap reduction. Analysis is conducted through observations of activity rates, employment rates, unemployment rates, inactivity rates, and long-term unemployment rates. With use of factor analysis we have identified the main factors on the labor markets in Europe and on the basis of cluster analysis we have conducted grouping of countries on the basis of discovered factors. Identification of cluster with Serbia was conducted and also the place of the Serbian labor market in the same cluster. On the basis of quantitative results qualitative analysis was conducted to overview the experience in the field of gender differences on the labor market in the countries from the same cluster as Serbia, with special attention to Italy. Contemporary researches define labor market policy measures oriented to reduction of inequalities in the field of paid and unpaid labor. Decrease of these inequalities will consequently lead to the increase of female labor supply on the market. Final result of this research is the recommendation of policy measures in order to reduce gender differences in economic activity with final goal of creating modern society in Serbia and convergence with the most advanced countries in that field.

Insights into mortality patterns and causes of death through a process point of view model.

Science.gov (United States)

Anderson, James J; Li, Ting; Sharrow, David J

2017-02-01

Process point of view (POV) models of mortality, such as the Strehler-Mildvan and stochastic vitality models, represent death in terms of the loss of survival capacity through challenges and dissipation. Drawing on hallmarks of aging, we link these concepts to candidate biological mechanisms through a framework that defines death as challenges to vitality where distal factors defined the age-evolution of vitality and proximal factors define the probability distribution of challenges. To illustrate the process POV, we hypothesize that the immune system is a mortality nexus, characterized by two vitality streams: increasing vitality representing immune system development and immunosenescence representing vitality dissipation. Proximal challenges define three mortality partitions: juvenile and adult extrinsic mortalities and intrinsic adult mortality. Model parameters, generated from Swedish mortality data (1751-2010), exhibit biologically meaningful correspondences to economic, health and cause-of-death patterns. The model characterizes the twentieth century epidemiological transition mainly as a reduction in extrinsic mortality resulting from a shift from high magnitude disease challenges on individuals at all vitality levels to low magnitude stress challenges on low vitality individuals. Of secondary importance, intrinsic mortality was described by a gradual reduction in the rate of loss of vitality presumably resulting from reduction in the rate of immunosenescence. Extensions and limitations of a distal/proximal framework for characterizing more explicit causes of death, e.g. the young adult mortality hump or cancer in old age are discussed.

Area law and vacuum reordering in harmonic networks

International Nuclear Information System (INIS)

Riera, A.; Latorre, J. I.

2006-01-01

We review a number of ideas related to area-law scaling of the geometric entropy from the point of view of condensed matter, quantum field theory, and quantum information. An explicit computation in arbitrary dimensions of the geometric entropy of the ground state of a discretized scalar free field theory shows the expected area law result. In this case, area-law scaling is a manifestation of a deeper reordering of the vacuum produced by majorization relations. Furthermore, the explicit control on all the eigenvalues of the reduced density matrix allows for a verification of entropy loss along the renormalization group trajectory driven by the mass term. A further result of our computation shows that single-copy entanglement also obeys area law scaling, majorization relations, and decreases along renormalization group flows

Human cortical activity evoked by the assignment of authenticity when viewing works of art

Directory of Open Access Journals (Sweden)

Mengfei eHuang

2011-11-01

Full Text Available The expertise of others is a major social influence on our everyday decisions and actions. Many viewers of art, whether expert or naïve, are convinced that the full aesthetic appreciation of an artwork depends upon the assurance that the work is genuine rather than fake. Rembrandt portraits provide an interesting image set for testing this idea, as there is a large number of them and recent scholarship has determined that quite a few fakes and copies exist. Use of this image set allowed us to separate the brain's response to images of genuine and fake pictures from the brain's response to external advice about the authenticity of the paintings. Using functional magnetic resonance imaging, viewing of artworks assigned as ‘copy’, rather than ‘authentic’, evoked stronger responses in frontopolar cortex (FPC and right precuneus, regardless of whether the portrait was actually genuine. Advice about authenticity had no direct effect on the cortical visual areas responsive to the paintings, but there was a significant psychophysiological interaction between the FPC and the lateral occipital area, which suggests that these visual areas may be modulated by FPC. We propose that the activation of brain networks rather than a single cortical area in this paradigm supports the art-scholars’ view that aesthetic judgments are multi-faceted and multi-dimensional in nature.
