Tímoria e páthos em Medeia, de Eurípides
Authors: Timbó Margarida Pontes , Oliveira Ângelo Bruno Lucas de
Published: February 2015

Este texto apresenta algumas considerações acerca da tímoria (a vingança) e do páthos (o sofrimento), na tragédia Medeia, de Eurípides, escrita por volta do século V a.C. A imagem da Medeia imortalizada para os leitores é aquela mulher melancólica, que sofre devido ao abandono do homem amado; monstruosa e vingativa, atinge o ápice de seu desespero quando mata os próprios filhos para ferir o esposo infiel. O ciúme serve de mote ao filicídio, gerando a tímoria e, em consequência, o páthos. Rejeitada pelo amado, Medeia simboliza a mulher impulsiva, passional, que castiga drasticamente o esposo pelo perjúrio cometido. Medeia trágica foge aos padrões da mulher ateniense da época de Eurípides; tal fato sugere que ela não seria o tipo de esposa ideal. A tragédia em foco prenuncia ao ateniense do período sua possível condição ao tornar-se grego: encontrar um caminho inverso ao da glória, o risco de tornar-se bárbaro como Medeia, reflexo da vingança e do sofrimento diante de infortúnios.
Aerial Laser Scanning in Archeology
Authors: Faltýnová Martina , Pavelka Karel
Published: February 2015

Technology of aerial laser scanning is often well used for a DTM generation. The DTM (digital surface model) displayed in appropriate form, e.g. shaded surface, can be used as a data source for searching for archaeological sites. Aerial laser scanning data acquisition is unfortunately too expensive for non-commercial projects.  It can be solution to use the ALS data acquired primarily for another reason by public service. This data has in general lower density, than expensive custom-made data, but can be borrowed for research purpose in a limited size. We tested the data from The Czech Office for Surveying, Mapping and Cadastre. The aim was to find, if it is possible to use data characterized by density of about 1 point/m2 for archaeological research. We used the DTM in form of shaded surface and inspect the data around few well known archaeological sites from different periods. It is also possible to use different outputs from the original DTM to better display terrain discontinuities, which could be caused by human activity.
Metadata and Tools for Integration and Preservation of Cultural Heritage 3D Information
Authors: Felicetti Achille , Lorenzini Matteo
Published: February 2015

In this paper we investigate many of the various storage, portability and interoperability issues arising among archaeologists and cultural heritage people when dealing with 3D technologies. On the one side, the available digital repositories look often unable to guarantee affordable features in the management of 3D models and their metadata; on the other side the nature of most of the available data format for 3D encoding seem to be not satisfactory for the necessary portability required nowadays by 3D information across different systems. We propose a set of possible solutions to show how integration can be achieved through the use of well known and wide accepted standards for data encoding and data storage. Using a set of 3D models acquired during various archaeological campaigns and a number of open source tools, we have implemented a straightforward encoding process to generate meaningful semantic data and metadata. We will also present the interoperability process carried out to integrate the encoded 3D models and the geographic features produced by the archaeologists. Finally we will report the preliminary (rather encouraging) development of a semantic enabled and persistent digital repository, where 3D models (but also any kind of digital data and metadata) can easily be stored, retrieved and shared with the content of other digital archives.

Published: February 2015

Constant improvements in the field of surveying, computing and distribution of digital-content are reshaping the way Cultural Heritage can be digitised and virtually accessed, even remotely via web. A traditional 2D approach for data access, exploration, retrieval and exploration may generally suffice, however more complex analyses concerning spatial and temporal features require 3D tools, which, in some cases, have not yet been implemented or are not yet generally commercially available. Efficient organisation and integration strategies applicable to the wide array of heterogeneous data in the field of Cultural Heritage represent a hot research topic nowadays. This article presents a visualisation and query tool (QueryArch3D) conceived to deal with multi-resolution 3D models. Geometric data are organised in successive levels of detail (LoD), provided with geometric and semantic hierarchies and enriched with attributes coming from external data sources. The visualisation and query front-end enables the 3D navigation of the models in a virtual environment, as well as the interaction with the objects by means of queries based on attributes or on geometries. The tool can be used as a standalone application, or served through the web. The characteristics of the research work, along with some implementation issues and the developed QueryArch3D tool will be discussed and presented.

Published: February 2015

The design and evaluation of virtual learning environments for construction and surveying students is presented in this paper; by combining virtual learning environment and on-site student surveys to model and replicate practice in the architectural heritage sector. The Virtual Learning Environment is enhanced with real live survey projects whereby students collect the data to build virtual historic buildings from onsite surveys using advanced survey equipment. The survey data is modelled in HBIM; Historic Building Information Modelling (HBIM) is currently being developed as a virtual learning tool for construction and surveying students in the Dublin Institute of Technology.  HBIM, is a novel solution whereby interactive parametric objects representing architectural elements are constructed from historic data, these elements, including detail behind the scan surface are accurately mapped onto a laser or image based survey. The architectural elements are scripted using a Geometric Descriptive Language GDL. In the case of this project a Virtual Learning Environment is being developed which combines advanced recording and surveying with Building Information Modelling (BIM) to simulate and analyse existing buildings.
Metric Accuracy Evaluation of Dense Matching Algorithms in Archeological Applications
Authors: Re C. , Robson S. , Roncella R. , Hess M
Published: February 2015

In the cultural heritage field the recording and documentation of small and medium size objects with very detailed Digital Surface Models (DSM) is readily possible by through the use of high resolution and high precision triangulation laser scanners. 3D surface recording of archaeological objects can be easily achieved in museums; however, this type of record can be quite expensive. In many cases photogrammetry can provide a viable alternative for the generation of DSMs. The photogrammetric procedure has some benefits with respect to laser survey. The research described in this paper sets out to verify the reconstruction accuracy of DSMs of some archaeological artifacts obtained by photogrammetric survey. The experimentation has been carried out on some objects preserved in the Petrie Museum of Egyptian Archaeology at University College London (UCL). DSMs produced by two photogrammetric software packages are compared with the digital 3D model obtained by a state of the art triangulation color laser scanner. Intercomparison between the generated DSM has allowed an evaluation of metric accuracy of the photogrammetric approach applied to archaeological documentation and of precision performances of the two software packages.
New Sensors for Cultural Heritage Metric Survey: The ToF Cameras
Authors: Chiabrando Filiberto , Piatti Dario , Rinaudo Fulvio
Published: February 2015

ToF cameras are new instruments based on CCD/CMOS sensors which measure distances instead of radiometry. The resulting point clouds show the same properties (both in terms of accuracy and resolution) of the point clouds acquired by means of traditional LiDAR devices. ToF cameras are cheap instruments (less than 10.000 €) based on video real time distance measurements and can represent an interesting alternative to the more expensive LiDAR instruments. In addition, the limited weight and dimensions of ToF cameras allow a reduction of some practical problems such as transportation and on-site management. Most of the commercial ToF cameras use the phase-shift method to measure distances. Due to the use of only one wavelength, most of them have limited range of application (usually about 5 or 10 m). After a brief description of the main characteristics of these instruments, this paper explains and comments the results of the first experimental applications of ToF cameras in Cultural Heritage 3D metric survey.  The possibility to acquire more than 30 frames/s and future developments of these devices in terms of use of more than one wavelength to overcome the ambiguity problem allow to foresee new interesting applications.
Surveying and Comparing the Arco Dei Gavi and its Historical Wooden Maquette
Authors: Guerra Francesco , Vernier Paolo
Published: February 2015

Actually geometrics’ science offers new opportunities and interesting applications in the field of Cultural Heritage. These applications are strictly related to preservation, restoration but even to cataloging and reproducing a monument that no longer has its original integrity.  The possibility of obtaining 3D data, of such a model close to reality, enables us to realize studies that sometimes are too complex or impossible. The paper will describe the study of a monumental arch, the Arco dei Gavi, built in Verona during the I sec. A.C., that was destroyed in 1805 by the Napoleonic army, and its wooden model that was realized in 1813 and it has a very important role concerning the monument’s reconstruction. The purpose is to realize two threedimensional models which can be comparable to each other, two models with recognizable differences, similarities and discontinuities about shapes and single elements that compose the monument. It should also be noted that some original parts of the monument have not been relocated but are badly preserved in a museum: the 3D digital model helps to identify these parts in their original location. The main steps of the work can be summarized in: collecting the historical documentation of Arco dei Gavi and its representations; identifying proper instruments (laser scanning and photogrammetric hardware and software); surveying the Arch and its wooden model; identifying a unique and shared reference system; comparing both digital models related to the same scale; choosing a three-dimensional representation to emphasize the results; reallocation of outstanding pieces (virtual anastylosis).
The Standard of Management and Application of Cultural Heritage Documentation
Authors: Ning Yen Ya , Hua Weng Kuo , Ming Cheng Hung , Shan Hsu Wei
Published: February 2015

Using digital technology for cultural heritage documentation is a global trend in the 21 st century. Many important techniques are currently under development, including 3D digital imaging, reverse engineering, GIS (Geographic Information Systems) etc. However, no system for overall management or data integration is yet available. Therefore, we urgently need such a system to efficiently manage and interpret data for the preservation of cultural heritages. This paper presents a digitizing process developed in Taiwan by the authors. To govern and manage cultural property, three phases of property conservation, registration, restoration and management, has been set up along a timeline. In accordance with the laws of cultural property, a structural system has been built for project management, including data classification and data interpretation with self-documenting characteristics. Through repository information and metadata, a system catalogue (also called data dictionary) (Figure 1) was created. The primary objective of the study is to create an integrated technology for an efficient management of databases. Several benefits could be obtained from this structural standard: (1) cultural heritage management documentation can be centralized to minimize the possibility of data re-entry resulting inconsistency, and also to facilitate simultaneous updating of data; (2) since multiple data can be simultaneously retrieved and saved in real time, the incidence of errors can be reduced; (3) this system could be easily tailored to meet the administrative requirements for the standardization of documentation exchanged between cultural properties institutions and various county and city governments.
Automated 3D-Objectdocumentation on the Base of an Image Set
Authors: Vetter Sebastian , Siedler Gunnar
Published: February 2015

Digital stereo-photogrammetry allows users an automatic evaluation of the spatial dimension and the surface texture of objects. The integration of image analysis techniques simplifies the automation of evaluation of large image sets and offers a high accuracy [1]. Due to the substantial similarities of stereoscopic image pairs, correlation techniques provide measurements of subpixel precision for corresponding image points. With the help of an automated point search algorithm in image sets identical points are used to associate pairs of images to stereo models and group them. The found identical points in all images are basis for calculation of the relative orientation of each stereo model as well as defining the relation of neighboured stereo models. By using proper filter strategies incorrect points are removed and the relative orientation of the stereo model can be made automatically. With the help of 3D-reference points or distances at the object or a defined distance of camera basis the stereo model is orientated absolute. An adapted expansion- and matching algorithm offers the possibility to scan the object surface automatically. The result is a three dimensional point cloud; the scan resolution depends on image quality. With the integration of the iterative closest point- algorithm (ICP) these partial point clouds are fitted to a total point cloud. In this way, 3D-reference points are not necessary. With the help of the implemented triangulation algorithm a digital surface models (DSM) can be created. The texturing can be made automatically by the usage of the images that were used for scanning the object surface. It is possible to texture the surface model directly or to generate orthophotos automatically. By using of calibrated digital SLR cameras with full frame sensor a high accuracy can be reached. A big advantage is the possibility to control the accuracy and quality of the 3d-objectdocumentation with the resolution of the images. The procedure described here is implemented in software Metigo 3D.
Image Based Modeling from Spherical Photogrammetry and Structure for Motion. The Case of the Treasury, Nabatean Architecture in Petra
Authors: D’Annibale E.
Published: February 2015

This research deals with an efficient and low cost methodology to obtain a metric and photorealstic survey of a complex architecture. Photomodeling is an already tested interactive approach to produce a detailed and quick 3D model reconstruction. Photomodeling goes along with the creation of a rough surface over which oriented images can be back-projected in real time. Lastly the model can be enhanced checking the coincidence between the surface and the projected texture. The challenge of this research is to combine the advantages of two technologies already set up and used in many projects: spherical photogrammetry (Fangi, 2007,2008,2009,2010) and structure for motion (Photosynth web service and Bundler + CMVS2 + PMVS2). The input images are taken from the same points of view to form the set of panoramic photos paying attention to use well-suited projections: equirectangular for spherical photogrammetry and rectilinear for Photosynth web service. The performance of the spherical photogrammetry is already known in terms of its metric accuracy and acquisition quickness but time is required in the restitution step because of the manual homologous point recognition from different panoramas. In Photosynth instead the restitution is quick and automated: the provided point clouds are useful benchmarks to start with the model reconstruction even if lacking in details and scale. The proposed workflow needs of ad-hoc tools to capture high resolution rectilinear panoramic images and visualize Photosynth point clouds and orientation camera parameters. All of them are developed in VVVV programming environment. 3DStudio Max environment is then chosen because of its performance in terms of interactive modeling, UV mapping parameters handling and real time visualization of projected texture on the model surface. Experimental results show how is possible to obtain a 3D photorealistic model using the scale of the spherical photogrammetry restitution to orient web provided point clouds. Moreover the proposed research highlights how is possible to speed up the model reconstruction without losing metric and photometric accuracy. In the same time, using the same panorama dataset, it picks out a useful chance to compare the orientations coming from the two mentioned technologies (Spherical Photogrammetry and Structure for Motion).

Vilnius Poker: The Reception of a Soviet Novel in the North American Market
Authors: Gailiūtė Gabrielė
Published: February 2015

The article discusses an interesting situation: a novel by a Lithuanian author, written still under the Soviet regime and published on the brink of the independence, has been translated and published in the USA. For the Lithuanian readers, the book is one of the most important literary documents of the historical situation of life in the Soviet times, as well as one of the greatest artistic achievements in the late-20th century Lithuanian literature. The article analyses the reactions of the American readers, employing the script acts theory as developed by Peter L. Shillingsburg: in what "sememic molecules" does the book appear to be framed as it travels across the Atlantic? The differences between the reactions of Lithuanian and American readers mentioned in the article cover the most prominent distinctions in the social and cultural context, but also, where the reader's own context does not provide a well-defined sememic molecule, there appears to be a way for publishing and editing decisions to guide the reader to adhere to a particular mode of reading.

Published: February 2015

Eustachian valve endocarditis caused by Actinomyces species is extremely rare. A literature review revealed only one reported case—caused by Actinomyces israelii in an intravenous drug abuser.

Our patient, a 30-year-old woman who at first appeared to be in good health, presented with fever, a large mobile mass on the eustachian valve, and extensive intra-abdominal and pelvic masses that looked malignant. Histopathologic examination of tissue found in association with an intrauterine contraceptive device revealed filamentous, branching microorganisms consistent with Actinomyces turicensis. This patient was treated successfully with antibiotic agents.

In addition to presenting a new case of a rare condition, we discuss cardiac actinomycotic infections in general and eustachian valve endocarditis in particular: its predisposing factors, clinical course, sequelae, and our approaches to its management.
The 1999 Stockholm Consensus Conference on quality specifications in laboratory medicine
Authors: Fraser Callum G.
Published: February 2015

The setting of analytical quality specifications in laboratory medicine has been a topic of discussion and debate for over 50 years: 15 years ago, as the subject matured and a profusion of recommendations appeared, many of them from expert groups, it was realised by a number of leading professionals that there was a need for a global consensus on the setting of such specifications. The Stockholm Conference held in 1999 on “Strategies to set global analytical quality specifications in laboratory medicine” achieved this and advocated the ubiquitous application of a hierarchical structure of approaches. The hierarchy has five levels, namely: 1) evaluation of the effect of analytical performance on clinical outcomes in specific clinical settings; 2) evaluation of the effect of analytical performance on clinical decisions in general using a) data based on components of biological variation, or b) analysis of clinicians’ opinions; 3) published professional recommendations from a) national and international expert bodies, or b) expert local groups or individuals; 4) performance goals set by a) regulatory bodies, or b) organisers of external quality assessment (EQA) schemes; and 5) goals based on the current state of the art as a) demonstrated by data from EQA or proficiency testing scheme, or b) found in current publications on methodology. This approach has been much used since its wide promulgation, but there have been ongoing criticisms and new developments. The time seems right for an objective reappraisal of recommended strategies to set analytical performance goals.

Published: February 2015

Reliable reference intervals for two novel urinary biomarkers of renal injury, neutrophil gelatinase-associated lipocalin (uNGAL) and kidney injury molecule-1 (uKIM-1) are lacking for infants. Therefore, the aim of our study was to establish reference intervals for urinary NGAL and KIM-1 absolute concentrations as well as normalized to urinary creatinine in young infants categorized in small age intervals.

From June 2010 to March 2014, serum and urine samples of 106 basically healthy infants (born between 37 and 42 weeks of gestation) aged 1 day to 1 year were collected. Blood samples were assayed for serum creatinine levels to confirm a healthy renal status. Urine samples were assayed for creatinine, uNGAL (ng/mL) and uKIM-1 (ng/mL).

Two thirds of the study cohort were boys. uNGAL concentrations declined with increasing age (likelihood ratio test, p=0.001). Also, uNGAL concentrations were higher in girls (50th centile uNGAL was 27.1 ng/mL) than boys (50th centile uNGAL was 14.3 ng/mL) (two tailed Wald test, p<0.001) NGAL concentrations were not related to ethnicity. uKIM-1 concentrations were extremely low in almost all 106 subjects [median uKIM-1 was 0.08 (IQR 0.08–0.08) ng/mL] and not related with age, gender or ethnicity (all p>0.05).

Our data uniquely provide uNGAL and uKIM-1 reference intervals for the first year of life. Notably, only uNGAL levels decreased with increasing age and were higher in girls. These reference intervals enable future studies to evaluate the performance of both biomarkers in detecting early kidney tubular injury, particularly in the setting of critical care.

Minor contribution of biliary excretion in lithium elimination in rats
Authors: Uwai Yuichi , Kawasaki Tatsuya , Nabekura Tomohiro
Published: February 2015

Background: Lithium, which is often used for the treatment of bipolar disorders, is mainly recovered into urine after being orally administered. Due to the fact that it is completely absorbed via the gastrointestinal tract, it remains unknown whether biliary excretion is involved in the lithium disposition. In this study, we examined biliary excretion of lithium in rats and compared these with renal excretion.

Materials and methods: After the injection of lithium chloride to femoral vein, plasma levels and excretion into urine and bile of lithium were evaluated.

Results: After its intravenous administration as a bolus, the plasma concentration of lithium decreased time-dependently. Until 60 min, 6.47% and 0.694% of injected lithium were excreted into urine and bile, respectively. The biliary clearance of lithium was calculated to be 0.0779 mL/min/kg, and this was 11.3% of the renal clearance.

Conclusions: These findings suggest the low ability of the liver to eliminate lithium from plasma in comparison with the kidney in rats.
A generative model for predicting outcomes in college basketball
Authors: Ruiz Francisco J. R. , Perez-Cruz Fernando
Published: February 2015

We show that a classical model for soccer can also provide competitive results in predicting basketball outcomes. We modify the classical model in two ways in order to capture both the specific behavior of each National collegiate athletic association (NCAA) conference and different strategies of teams and conferences. Through simulated bets on six online betting houses, we show that this extension leads to better predictive performance in terms of profit we make. We compare our estimates with the probabilities predicted by the winner of the recent Kaggle competition on the 2014 NCAA tournament, and conclude that our model tends to provide results that differ more from the implicit probabilities of the betting houses and, therefore, has the potential to provide higher benefits.
Consolidation and Strengthening of Historical Masonry by Means of Mineral Grouts: Modeling Structural Behavior of Grouted Three-Leaf Masonry
Authors: Van Gemert Dionys , Toumbakari Eleni-Eva , Ignoul Sven , Brosens Kris
Published: February 2015

Development of mineral grouts for consolidation and strengthening of historical masonry was discussed in Ref. [1]. The properties of the injection grout must counteract the elements that initiate the failure mechanism of multiple leaf historical masonry and lead to its collapse. This paper presents a macro-approach to model the structural behavior of three-leaf masonry. A global approach is used, based on the properties and the behavior of the external leafs, in combination with the properties and behavior of the central core of the three-leaf wall. Evaluation of the models is made by comparison with experimental data.
Increased hospital admissions associated with extreme-heat exposure in King County, Washington, 1990–2010

Published: February 2015

Increased morbidity and mortality have been associated with extreme heat events, particularly in temperate climates. Few epidemiologic studies have considered the impact of extreme heat events on hospitalization rates in the Pacific Northwest region. This study quantifies the historic (May to September 1990–2010) heat-morbidity relationship in the most populous Pacific Northwest County, King County, Washington. A relative risk (RR) analysis was used to explore the association between heat and all non-traumatic hospitalizations on 99th percentile heat days, whereas a time series analysis using a piecewise linear model approximation was used to estimate the effect of heat intensity on hospitalizations, adjusted for temporal trends and day of the week. A non-statistically significant 2% [95% CI: 1.02 (0.98, 1.05)] increase in hospitalization risk, on a heat day vs. a non-heat day, was noted for all-ages and all non-traumatic causes. When considering the effect of heat intensity on admissions, we found a statistically significant 1.59% (95% CI: 0.9%, 2.29%) increase in admissions per degree increase in humidex above 37.4°C. Admissions stratified by cause and age produced statistically significant results with both relative risk and time series analyses for nephritis and nephrotic syndromes, acute renal failure, and natural heat exposure hospitalizations. This study demonstrates that heat, expressed as humidex, is associated with increased hospital admissions. When stratified by age and cause of admission, the non-elderly age groups (<85 years) experience significant risk for nephritis and nephrotic syndromes, acute renal failure, natural heat exposure, chronic obstructive pulmonary disease, and asthma hospitalizations.
Structures, Stabilities, and Electronic Properties for Rare-Earth Lanthanum Doped Gold Clusters
Authors: Zhao Ya-Ru
Published: February 2015

The structures, stabilities, and electronic properties of rare-earth lanthanum doped gold La2Au
n
(n = 1–9) and pure gold Au
n
(n ≤ 11) clusters have been investigated by using density functional theory. The optimized geometries show that the lowest energy structures of La2Au
n
clusters favour the 3D structure at n ≥ 3. The lanthanum atoms can strongly enhance the stabilities of gold clusters and tend to occupy the most highly coordinated position. By analysing the gap, vertical ionization potential, and chemical hardness, it is found that the La2Au6 isomer possesses higher stability for small-sized La2Au
n
clusters (n = 1–9). The charges in the La2Au
n
clusters transfer from La atoms to the Au
n
host. In addition, Wiberg bond indices analysis reveals that the intensity of different bonds of La2Au
n
clusters exhibits a sequence of La–La bond > La-Au bond > Au–Au bond.

Acute pancreatitis is one of the most common diseases of the gastrointestinal tract associated with significant morbidity and mortality that requires up-to-date and evidence based treatment guidelines. The Hungarian Pancreatic Study Group proposed to prepare evidence based guideline for the medical and surgical management of acute pancreatitis based on the available international guidelines and evidence. The preparatory and consultation task force appointed by the Hungarian Pancreatic Study Group translated and, if it was necessary, complemented and/or modified the international guidelines. All together 42 relevant clinical questions were defined in 11 topics (Diagnosis and etiology, Prognosis, Imaging, Fluid therapy, Intensive care management, Prevention of infectious complications, Nutrition, Biliary interventions, Post-endoscopic retrograde cholangio-pancreatography pancreatitis, Indication, timing and strategy for intervention in necrotizing pancreatitis, Timing of cholecystectomy [or endoscopic sphincterotomy]). Evidence was classified according to the UpToDate®grading system. The draft of the guideline was presented and discussed at the consensus meeting on September 12, 2014. 25 clinical questions with almost total (more than 95%) and 17 clinical questions with strong (more than 70%) agreement were accepted. The present guideline is the first evidence based acute pancreatitis guideline in Hungary. The guideline may provide important help for tuition, everyday practice and for establishment of proper finance of acute pancreatitis. Therefore, the authors believe that these guidelines will widely become as basic reference in Hungary. Orv. Hetil., 2015, 156(7), 244–261.

Autoimmune pancreatitis is a rare disease which can even mimic pancreatic tumor, however, unlike the latter, it requires not surgical but conservative management. Correct diagnosis and differential diagnosis of autoimmune pancreatitis and treatment of these patients requires up-to-date and evidence based management guidelines. The Hungarian Pancreatic Study Group proposed to prepare an evidence based guideline based on the available international guidelines and evidences. The preparatory and consultation task force appointed by the Hungarian Pancreatic Study Group translated and complemented and/or modified the international guidelines if it was necessary. 29 relevant clinical questions in 4 topics were defined (Basics; Diagnosis; Differential diagnostics; Therapy). Evidence was classified according to the UpToDate®grading system. The draft of the guidelines was presented and discussed at the consensus meeting on September 12, 2014. All clinial questions were accepted with almost total (more than 95%) agreement. The present guideline is the first evidence based autoimmune pancreatitis guideline in Hungary. The guideline may provide very important and helpful data for tuition of autoimmune pancreatitis, for everyday practice and for establishing proper finance. Therefore, the authors believe that these guidelines will widely become a basic reference in Hungary. Orv. Hetil., 2015, 156(8), 292–307.

Background: The small bioactive lipid lysophosphatidic acid (LPA) plays critical roles in both normal physiology and inflammation in many systems. However, its actions are just beginning to be defined in oral biology and pathophysiology.

Methods: Microarray analysis was used to test the hypothesis that human gingival fibroblasts (GFs) would show significant changes in wound‐healing and inflammation‐related gene transcripts in response to a major human salivary and gingival crevicular fluid LPA species, 18:1, and that they would express transcript for the major LPA‐producing enzyme autotaxin. The microarray results were validated for three highly relevant upregulated inflammatory transcripts using quantitative reverse transcription‐polymerase chain reaction (QRT‐PCR). Liquid chromatography‐tandem mass spectrometry was used to assay time‐dependent LPA species production by GFs.

Results: LPA 18:1 significantly regulated 20 GF novel and 27 known genes linked to the control of inflammation (P ≤0.01). QRT‐PCR validation of interleukin (IL)‐8, IL‐11, and suppressor of cytokine signaling 2 (SOCS2) messenger RNAs confirmed statistically significant differences from control (P ≤0.05). Autotaxin transcript was present, and GFs were found to produce multiple LPA species in a time‐dependent manner.

Conclusions: The upregulation of transcripts for known GF proinflammatory (IL‐6, IL‐8) and anti‐inflammatory (IL‐11) ILs, along with SOCS2, shows that LPA transiently regulates a complex set of GF genes critical to periodontal wound healing and inflammation. These results implicate LPA exerting actions on GFs that are compatible with functioning as a mediator in oral fibroblast biology and inflammatory responses. Therefore, LPA may potentially modulate/regulate periodontal inflammation.
3D stratigraphic and structural synthesis of the Dannemarie basin (Upper Rhine Graben)
Authors: Le Carlier de Veslud Christian , Bourgeois Olivier , Diraison Marc , Ford Mary
Published: February 2015

The Dannemarie basin is the southwesternmost depocentre of the Upper Rhine Graben, which belongs to the West-European Tertiary rift system. It is bounded to the west by the Vosges mountains, to the south by the folded Jura belt and to the east by the Mulhouse block. The rifting reached its maximum activity during the Priabonian and early Rupelian (35-31 Ma). In the framework of the GeoFrance 3D project “Fossé rhénan”, a 3D geometrical model of the Dannemarie basin was built in the gOcad 3D modeler. It incorporates the BRGM well database and geological maps, and 40 seismic cross-sections. These data are used to study the structure and geological history of the area. Seismic data have been converted from time to depth using a 1D time-to-depth polynomial law deduced from the analysis of the Bellemagny borehole. The Dannemarie basin is bounded to the west by the Vosges fault zone and to the east by the Illfurth fault zone. On both borders, basin subsidence was controlled by normal faults and associated syn-rift flexures. The minimum throw on the Vosges fault zone is about 1400 m to the north of the model, decreasing to the south, where it is replaced by a syn-rift flexure. On the Illfurth fault zone, subsidence is accommodated by faults (with about 1000 m throw) and by a flexure (about 300 m). Stratigraphic data indicate that these flexures were active during Priabonian and early Rupelian extension. These monoclinal flexures are interpreted as fault-propagation folds that developed above upward propagating normal faults in the basement. As displacement accumulates, the fault propagates upwards and cuts the overlying fold. Similar fault-fold geometries have been described on the western border of the Rhine graben, close to Colmar and in other extensional tectonic contexts. In the Colmar area, the Vosges fault zone cuts through the basin margin fold, while further south along the western border of the Dannemarie basin, displacement on the fault decreases and subsidence is accommodated on a major flexure. Flexure locations correspond to gravimetric discontinuities attributed to Variscan structures, suggesting reactivation of deep structures during rifting. The Illfurth fault zone displays upwardly divergent fault geometries that resemble “flower structures”. The data can be interpreted as follows, either that (a) the Illfurth fault zone accommodated a minor sinistral strike-slip component due to a post-Miocene NW-SE compressive regional stress field or (b) these faults developed in association with the fault propagation folds.
The Role of Sustainable Development Planning in Our Industry

Sustainable Development

Sustainability, nontechnical risk, environmental and social performance, as well as corporate (social) responsibility are interrelated terms that refer to an important set of competencies viewed as increasingly strategic in value for the oil and gas industry. Over the past 15 years, sustainability as a term has matured from its initial “green” scope to embrace social agendas and has evolved from being an external force to become a set of organizational values and operating principles that govern development and operations in the oil and gas sector. A plethora of standards, guidelines, and good and best practices have been created by various sectors with the oil and gas industry being one of the most active in evolving its own guidelines. Both corporate strategy and corporate risk management have identified opportunities and risks and built in new checkpoints in their processes.

Consequently, securing and maintaining a license to operate (as well as growing the commercial value beyond this threshold) extends well beyond legislative and regulatory permitting to encompass both the mitigation of adverse social and environmental effects as well as the advancement of financial, societal, and environmental benefits by the execution of strong sustainability performance. Significant to this is the new organizational refinements on, not just the license to operate, but also new phrasing such as “social license to operate” and “permission to operate” with the accompanying strategic financial benefits of becoming a preferred developer or operator.

Given the increasing prominence of sustainability in the oil and gas industry, SPE embarked on a path in 2010 when it created a Sustainability Task Force to

Refixation of Osteochondral Fractures by an Ultrasound-Activated Pin System – An Ovine In Vivo Examination Using CT and Scanning Electron Microscope
Authors: H Neumann , A.P Schulz , S Breer , A Unger , B Kienast
Published: February 2015

Background:

Osteochondral injuries, if not treated appropriately, often lead to severe osteoarthritis of the affected joint. Without refixation of the osteochondral fragment, human cartilage only repairs these defects imperfectly. All existing refixation systems for chondral defects have disadvantages, for instance bad MRI quality in the postoperative follow-up or low anchoring forces. To address the problem of reduced stability in resorbable implants, ultrasound-activated pins were developed. By ultrasound-activated melting of the tip of these implants a higher anchoring is assumed. Aim of the study was to investigate, if ultrasound-activated pins can provide a secure refixation of osteochondral fractures comparing to conventional screw and conventional, resorbable pin osteosynthesis. CT scans and scanning electron microscopy should proovegood refixation results with no further tissue damage by the melting of the ultrasound-activated pins in comparison to conventional osteosynthesis.

Methods:

Femoral osteochondral fragments in sheep were refixated with ultrasound-activated pins (SonicPin™), Ethipins®and screws (Asnis™). The quality of the refixated fragments was examined after three month of full weight bearing by CT scans and scanning electron microscopy of the cartilage surface.

Results:

The CT examination found almost no statistically significant difference in the quality of refixation between the three different implants used. Concerning the CT morphology, ultrasound-activated pins demonstrated at least the same quality in refixation of osteochondral fragments as conventional resorbable pins or screws. The scanning electron microscopy showed no major surface damage by the three implants, especially any postulated cartilage damage induced by the heat of the ultrasound-activated pin. The screws protruded above the cartilage surface, which may affect the opposingtibial surface.

Conclusion:

Using CT scans and scanning electron microscopy, the SonicPin™, the Ethipin®and screws were at least equivalent in refixation quality of osteochondral fragments.

Authors: Yuan Shi-Fang , Wang Qing-Wen , Xiong Zhi-Ping
Published: February 2015

For any A=A1+A2j?Qnxn and ?? {i,j,k} denote A?H = -?AH?. If A?H =
A,A is called an ?-Hermitian matrix. If A?H =-A,A is called an
?-anti-Hermitian matrix. Denote ?-Hermitian matrices and ?-anti-Hermitian
matrices by ?HQnxn and ?AQnxn, respectively. In this paper, we consider the
least squares ?-Hermitian problems of quaternion matrix equation AHXA+ BHYB =
C by using the complex representation of quaternion matrices, the
Moore-Penrose generalized inverse and the Kronecker product of matrices. We
derive the expressions of the least squares solution with the least norm of
quaternion matrix equation AHXA + BHYB = C over [X,Y] ? ?HQnxn x ?HQkxk,
[X,Y] ? ?AQnxn x ?AQkxk, and [X,Y] ? ?HQnxn x ?AQkxk, respectively.
Oscillation behavior of third-order nonlinear neutral dynamic equations on time scales with distributed deviating arguments
Authors: Şenel Tamer , Utku Nadide
Published: February 2015

The aim of this paper is to give oscillation criteria for the third-order
neutral dynamic equations with distributed deviating arguments of the form
[r(t)([x(t)+p(t)x(?(t))]??)?]? + ?dc f(t,x[?(t,?)])?? = 0; where ?>0 is the
quotient of odd positive integers with r(t) and p(t) real-valued
rd-continuous positive functions defined on T. By using a generalized Riccati
transformation and integral averaging technique, we establish some new
sufficient conditions which ensure that every solution of this equation
oscillates or converges to zero.
