In order to ensure interoperability between middleware and authorization infrastructures used in the Open Science Grid (OSG) and the Enabling Grids for E-sciencE (EGEE) projects, an Authorization Interoperability activity was initiated in 2006. The interoperability goal was met in two phases: first, agreeing on a common authorization query interface and protocol with an associated profile that ensures standardized use of attributes and obligations; and second, implementing, testing, and deploying, on OSG and EGEE, middleware that supports the interoperability protocol and profile. The activity has involved people from OSG, EGEE, the Globus Toolkit project, and the Condor project. This paper presents a summary of the agreed-upon protocol, profile and the software components involved.

The GLUE information schema has been in use in the LCG/EGEE production Grid since the first version was defined in 2002. In 2007 a major redesign of GLUE, version 2.0, was started in the context of the Open Grid Forum following the creation of the GLUE Working Group. This process has taken input from a number of Grid projects, but as a major user of the version 1 schema LCG/EGEE has had a strong interest that the new schema should support its needs. In this paper we discuss the structure of the new schema in the light of the LCG/EGEE requirements and explain how they are met, and where improvements have been achieved compared with the version 1 schema. In particular we consider some difficulties encountered in recent extensions of the use of the version 1 schema to aid resource accounting in LCG, to enable the use of the SRM version 2 storage protocol by the LHC experiments, and to publish information about a wider range of services to improve service discovery. We describe how these can be better met by the new schema, and we also discuss the way in which the transition to the new schema is being managed.

Encrypted Data Storage in EGEE

The medical community is routinely using clinical images and associated medical data for diagnosis, intervention planning and therapy follow-up. Medical imaging is producing an increasing number of digital images for which computerized archiving, processing and analysis are needed. Grids are promising infrastructures for managing and analyzing the huge medical databases. Given the sensitive nature of medical images, practiotionners are often reluctant to use distributed systems though. Security if often implemented by isolating the imaging network from the outside world inside hospitals. Given the wide scale distribution of grid infrastructures and their multiple administrative entities, the level of security for manipulating medical data should be particularly high. In this presentation we describe the architecture of a solution, the gLite Encrypted Data Storage (EDS), which was developed in the framework of Enabling Grids for E-sciencE (EGEE), a project of the European Commission (contract number INFSO--508...

Data management is one of the cornerstones in the distributed production computing environment that the EGEE project aims to provide for a e-Science infrastructure. We have designed and implemented a set of services and client components, addressing the diverse requirements of all user communities. LHC experiments as main users will generate and distribute approximately 15 PB of data per year worldwide using this infrastructure. Another key user community, biomedical projects, have strict security requirements with less emphasis on the volume of data. We maintain three service groups for grid data management: The Disk Pool Manager (DPM) Storage Element (with more than 100 instances deployed world-wide), the LCG File Catalogue (LFC) and the File Transfer Service (FTS) which sustains an aggregated transfer rate of 1.5GB/sec. They are complemented by individual client components and also tools which help coordinating more complex uses cases with multiple services (GFAL-client, lcg util, eds-cli). In this paper we show how these services, keeping clean and standard interfaces among each other, can work together to cover the data flow and how they can be used as individual components to cover diverse requirements. We will also describe areas that we consider for further improvements, both for performance and functionality.

2011-01-01

The GLUE information schema has been in use in the LCG/EGEE production Grid since the first version was released in 2002. In 2008 a major redesign of GLUE, version 2.0, was defined in the context of the Open Grid Forum. The implementation of the publication and use of the new schema is a complex process which needs to be carefully managed to avoid any disruption to the production service, especially in the light of the end of the EGEE project and the transition to the new middleware and operational structures in EGI. In this paper we discuss the LDAP rendering of the schema, the upgrading of the Grid information system to allow both schemas to be used in parallel, the design and rollout of information providers, and the plans for migrating client software which uses the schema information. In particular we consider the implications for the specific requirements of the LCG project, especially regarding storage systems, accounting and monitoring.

Electron microscopy (EM) is a crucial technique, which allows Structural Biology researchers to characterize macromolecular assemblies in distinct functional states. Image processing in three dimensional EM (3D-EM) is used by a flourishing community (exemplarized by the EU funded 3D-EM NoE) and is characterized by voluminous data and large computing requirements, making this a problem well suited for Grid computing and the EGEE infrastructure. There are various steps in the 3D-EM refinement process that may benefit from Grid computing. To start with, large numbers of experimental images need to be averaged. Nowadays, typically tens of thousands of images are used, while future studies may routinely employ millions of images. Our group has been developing Xmipp, a package for single-particle 3D-EM image processing. Using Xmipp, the classification of 91,000 ribosome projections into 4 classes took more than 2500 CPU hours using the resources of the MareNostrum supercomputer at the Barcelona Supercomputing Centr...

User and virtual organisation support in EGEE Providing adequate user support in a grid environment is a very challenging task due to the distributed nature of the grid. The variety of users and the variety of Virtual Organizations (VO) with a wide range of applications in use add further to the challenge. The people asking for support are of various kinds. They can be generic grid beginners, users belonging to a given Virtual Organization and dealing with a specific set of applications, site administrators operating grid services and local computing infrastructures, grid monitoring operators who check the status of the grid and need to contact the specific site to report problems; to this list can be added network specialists and others. Wherever a user is located and whatever the problem experienced is, a user expects from a support infrastructure a given set of services. A non-exhaustive list is the following: a) a single access point for support; b) a portal with a well structured sources of information a...

Parallel execution of chemical software on EGEE Grid

CERN Document Server

Sterzel, Mariusz

2008-01-01

Constant interest among chemical community to study larger and larger molecules forces the parallelization of existing computational methods in chemistry and development of new ones. These are main reasons of frequent port updates and requests from the community for the Grid ports of new packages to satisfy their computational demands. Unfortunately some parallelization schemes used by chemical packages cannot be directly used in Grid environment. Here we present a solution for Gaussian package. The current state of development of Grid middleware allows easy parallel execution in case of software using any of MPI flavour. Unfortunately many chemical packages do not use MPI for parallelization therefore special treatment is needed. Gaussian can be executed in parallel on SMP architecture or via Linda. These require reservation of certain number of processors/cores on a given WN and the equal number of processors/cores on each WN, respectively. The current implementation of EGEE middleware does not offer such f...

Gridification: Porting New Communities onto the WLCG/EGEE Infrastructure

2007-01-01

The computational and storage capability of the Grid are attracting several research communities and we will discuss the general patterns observed in supporting new applications, porting them on the EGEE environment. In this talk we present the general infrastructure we have developed inside the application and support team at CERN (PSS and GD groups) to merge in a fast and feasible way all these applications inside the Grid, as for example Geant4, HARP, Garfield, UNOSAT or ITU. All these communities have different goals and requirements and the main challenge is the creation of a standard and general software infrastructure for the immersion of these communities onto the Grid. This general infrastructure effectively ‘shields’ the applications from the details of the Grid (the emphasis here is to run applications developed independently from the Grid middleware).It is stable enough to require few controls and supports by the members of the Grid team and also of the members of the user communities. Finally...

In the last fifteen years the approach of the computational Grid has changed the way to use computing resources. Grid computing has raised interest worldwide in academia, industry, and government with fast development cycles. Great efforts, huge funding and resources have been made available through national, regional and international initiatives aiming at providing Grid infrastructures, Grid core technologies, Grid middle ware and Grid applications. The Grid software layers reflect the architecture of the services developed so far by the most important European and international projects. In this paper Grid e-Infrastructure story is given, detailing European, Italian and international projects such as EGEE, INFN-Grid and NAREGI. In addition the sustainability issue in the long-term perspective is described providing plans by European and Italian communities with EGI and IGI.

Grids have the potential to revolutionise computing by providing ubiquitous, on demand access to computational services and resources. They promise to allow for on demand access and composition of computational services provided by multiple independent sources. Grids can also provide unprecedented levels of parallelism for high-performance applications. On the other hand, grid characteristics, such as high heterogeneity, complexity and distribution create many new technical challenges. Among these technical challenges, failure management is a key area that demands much progress. A recent survey revealed that fault diagnosis is still a major problem for grid users. When a failure appears at the user screen, it becomes very difficult for the user to identify whether the problem is in the application, somewhere in the grid middleware, or even lower in the fabric that comprises the grid. In this paper we present a tool able to check if a given grid service works as expected for a given set of users (Virtual Organisation) on the different resources available on a grid. Our solution deals with grid services as single components that should produce an expected output to a pre-defined input, what is quite similar to unit testing. The tool, called Service Availability Monitoring or SAM, is being currently used by several different Virtual Organizations to monitor more than 300 grid sites belonging to the largest grids available today. We also discuss how this tool is being used by some of those VOs and how it is helping in the operation of the EGEE/WLCG grid

Blueprint and First Experiences Bridging Hardware Virtualization and Global Grids for Advanced Scientific Computing: Designing and Building a Global Edge Services Framework (ESF) for OSG, EGEE, and LCG

We report on first experiences with building and operating an edge services framework (ESF) based on Xen virtual machines instantiated via the workspace service in Globus toolkit, and developed as a joint project between EGEE, LCG, and OSG. Many computing facilities are architected with their compute and storage clusters behind firewalls. Edge services (ES) are instantiated on a small set of gateways to provide access to these clusters via standard grid interfaces. Experience on EGEE, LCG, and OSG has shown that at least two issues are of critical importance when designing an infrastructure in support of ES. The first concerns ES configuration. It is impractical to assume that each virtual organization (VO) using a facility will employ the same ES configuration, or that different configurations will coexist easily. Even within a VO, it should be possible to run different versions of the same ES simultaneously. The second issue concerns resource allocation: it is essential that an ESF be able to effectively gu...

2010-01-01

Interoperability of grid infrastructures is becoming increasingly important in the emergence of large scale grid infrastructures based on national and regional initiatives. To achieve interoperability of grid infrastructures adaptions and bridging of many different systems and services needs to be tackled. A grid infrastructure offers services for authentication, authorization, accounting, monitoring, operation besides from the services for handling and data and computations. This paper presents an outline of the work done to integrate the Nordic Tier-1 and 2s, which for the compute part is based on the ARC middleware, into the WLCG grid infrastructure co-operated by the EGEE project. Especially, a throughout description of integration of the compute services is presented.

The distributed data analysis using Grid resources is one of the fundamental applications in high energy physics to be addressed and realized before the start of LHC data taking. The need to facilitate the access to the resources is very high. In every experiment up to a thousand physicist will be submitting analysis jobs into the Grid. Appropriate user interfaces and helper applications have to be made available to assure that all users can use the Grid without too much expertise in Grid technology. These tools enlarge the number of grid users from a few production administrators to potentially all participating physicists. The GANGA job management system (http://cern.ch/ganga), developed as a common project between the ATLAS and LHCb experiments provides and integrates these kind of tools. GANGA provides a simple and consistent way of preparing, organizing and executing analysis tasks within the experiment analysis framework, implemented through a plug-in system. It allows trivial switching between running test jobs on a local batch system and running large-scale analyzes on the Grid, hiding Grid technicalities. We will be reporting on the plug-ins and our experiences of distributed data analysis using GANGA within the ATLAS experiment and the EGEE/LCG infrastructure. The integration with the ATLAS data management system DQ2 into GANGA is a key functionality. In combination with the job splitting mechanism large amounts of jobs can be sent to the locations of data following the ATLAS computing model. GANGA supports tasks of user analysis with reconstructed data and small scale production of Monte Carlo data

Experiences with the GLUE information schema in the LCG/EGEE production grid

2008-01-01

A common information schema for the description of Grid resources and services is an essential requirement for interoperating Grid infrastructures, and its implementation interacts with every Grid component. In this context, the GLUE information schema was originally defined in 2002 as a joint project between the European DataGrid and DataTAG projects and the US iVDGL. The schema has major components to describe Computing and Storage Elements, and also generic Service and Site information. It has been used extensively in the LCG/EGEE Grid, for job submission, data management, service discovery and monitoring. In this paper we present the experience gained over the last five years, highlighting both successes and problems. In particular, we consider the importance of having a clear definition of schema attributes; the construction of standard information providers and difficulties encountered in mapping an abstract schema to diverse real systems; the configuration of publication in a way which suits system managers and the varying characteristics of Grid sites; the validation of published information; the ways in which information can be used (and misused) by Grid services and users; and issues related to managing schema upgrades in a large distributed system

In this research, the phenolic composition, antioxidant, antibacterial and cytotoxic activities of the methanolic extracts obtained from Alyssum fulvescens var. fulvescens aerial parts known as Ege kuduzotu in western Turkey, were firstly investigated. The antioxidant activity of the extract was determined by DPPH, metal chelating, phosphomolybdenum, β-carotene/linoleic acid and ferric reducing power assays. Moreover, total phenolic and flavonoid contents in the extract were investigated. The brine shrimp (Artemia salina L.) lethality test was used to investigate for the possible cytotoxic activity of the extract. Microdilution broth method was used to study antibacterial potency of extract against Gram-positive and Gram-negative bacteria. The extract exhibited good biological activities. Total phenolic and flavonoid contents in the extract were significantly correlated with antioxidant potentials. HPLC analysis showed that chlorogenic acid was the major phenolic in extract tested. The results indicated that the extract of A. fulvescens var. fulvescens may be considered as a potential source of biological agents and in vivo investigations are needed to test the biological effects of A. fulvescens var. fulvescens.

Flowability of bulk solids used in shale fracturing grouts as determined by the Jenike and Johanson method

Smooth operation of the shale fracturing facility at Oak Ridge National Laboratory requires that an even, uninterrupted flow of dry solids be delivered to a mixer at a rate of approximately 1200 lb/min. Some operational difficulties have been experienced with the dry solids system at the existing facility. Occasionally the solids flow from a bin was difficult to initiate or was irregular, particularly when the storage bin was nearly empty. A new shale fracturing facility is now being designed with a solids handling system that will eliminate the current problems. This report describes the tests made to obtain the necessary information about bulk-flow properties of the dry solids that are required for the facility modifications. Flow properties of fly ash, attapulgite, pottery clay, and a blended solids mix were determined in a Jenike and Johanson Flowfactor Tester. Tests with this unit involve the consolidation of a solid at a given pressure and the measurement of the force required to create a shear plane. The procedure is repeated several times at different consolidating pressures to determine a locus of points that can be displayed graphically. Results indicate that a bottom-hopper opening of about 4 ft will be required on the new, bulk storage bins if mass flow is to be achieved. It was also found that the existing bins are quite unsuitable for either their present function or their proposed function. Since these bins have served moderately well for 14 years, the effect of aeration is obviously major; these tests indicate only an upper limit to the size of the hopper opening that will be required. Pottery clay and attapulgite were found to have flow characteristics considerably inferior to blended solids. It is known, however, that attapulgite clay will flow from the existing bins, and modification of the bin bottoms to enlarge the openings does not appear to be justified

The Authorization Interoperability activity was initiated in 2006 to foster interoperability between middleware and authorization infrastructures deployed in the Open Science Grid (OSG) and the Enabling Grids for E-sciencE (EGEE) projects. This activity delivered a common authorization protocol and a set of libraries that implement that protocol. In addition, a set of the most common Grid gateways, or Policy Enforcement Points (Globus Toolkit v4 Gatekeeper, GridFTP, dCache, etc.) and site authorization services, or Policy Decision Points (LCAS/LCMAPS, SCAS, GUMS, etc.) have been integrated with these libraries. At this time, various software providers, including the Globus Toolkit v5, BeStMan, and the Site AuthoriZation service (SAZ), are integrating the authorization interoperability protocol with their products. In addition, as more and more software supports the same protocol, the community is converging on LCMAPS as a common module for identity attribute parsing and authorization call-out. This paper presents this effort, discusses the status of adoption of the common protocol and projects the community work on authorization in the near future.

Ubiquitin ligases of the N-end rule pathway: assessment of mutations in UBR1 that cause the Johanson-Blizzard syndrome.

Directory of Open Access Journals (Sweden)

Cheol-Sang Hwang

Full Text Available Johanson-Blizzard syndrome (JBS; OMIM 243800 is an autosomal recessive disorder that includes congenital exocrine pancreatic insufficiency, facial dysmorphism with the characteristic nasal wing hypoplasia, multiple malformations, and frequent mental retardation. Our previous work has shown that JBS is caused by mutations in human UBR1, which encodes one of the E3 ubiquitin ligases of the N-end rule pathway. The N-end rule relates the regulation of the in vivo half-life of a protein to the identity of its N-terminal residue. One class of degradation signals (degrons recognized by UBR1 are destabilizing N-terminal residues of protein substrates.Most JBS-causing alterations of UBR1 are nonsense, frameshift or splice-site mutations that abolish UBR1 activity. We report here missense mutations of human UBR1 in patients with milder variants of JBS. These single-residue changes, including a previously reported missense mutation, involve positions in the RING-H2 and UBR domains of UBR1 that are conserved among eukaryotes. Taking advantage of this conservation, we constructed alleles of the yeast Saccharomyces cerevisiae UBR1 that were counterparts of missense JBS-UBR1 alleles. Among these yeast Ubr1 mutants, one of them (H160R was inactive in yeast-based activity assays, the other one (Q1224E had a detectable but weak activity, and the third one (V146L exhibited a decreased but significant activity, in agreement with manifestations of JBS in the corresponding JBS patients.These results, made possible by modeling defects of a human ubiquitin ligase in its yeast counterpart, verified and confirmed the relevance of specific missense UBR1 alleles to JBS, and suggested that a residual activity of a missense allele is causally associated with milder variants of JBS.

2007-01-01

Using the Grid Infrastructures provided by EGEE, OSG and others, a worldwide production service has been built that provides the computing and storage needs for the 4 main physics collaborations at CERN's Large Hadron Collider (LHC). The large number of users, their geographical distribution and the very high service availability requirements make this experience of Grid usage worth studying for the sake of a solid and scalable future operation. This service must cater for the needs of thousands of physicists in hundreds of institutes in tens of countries. A 24x7 service with availability of up to 99% is required with major service responsibilities at each of some ten T ier1 a nd of the order of one hundred T ier2 s ites. Such a service - which has been operating for some 2 years and will be required for at least an additional decade - has required significant manpower and resource investments from all concerned and is considered a major achievement in the field of Grid computing. We describe the main lessons learned in offering a production service across heterogeneous Grids as well as the requirements for long-term operation and sustainability. (Author)

This service must cater for the needs of thousands of physicists in hundreds of institutes in tens of countries. A 24x7 service with availability of up to 99% is required with major service responsibilities at each of some ten "Tier1" and of the order of one hundred "Tier2" sites. Such a service - which has been operating for some 2 years and will be required for at least an additional decade - has required significant manpower and resource investments from all concerned and is considered a major achievement in the field of Grid computing. We describe the main lessons...

Full Text Available The scope of this study was the surface distribution modeling of precipitation in Anatolia and the Aegean Region which covers the western part of our country. The precipitation was handled in terms of 10 year segments and applied with Interactive 3D Analysis, Geographically Intensive Regression, Radial Basis Function and Quadratic Trend Analysis after which a precipitation dispersion map was established. It was concluded that planetary factors had a primary impact on the dispersion and change of precipitation in the region. On the other hand, topographical characteristics were determining for local precipitation changes, it was particularly evident that the northern parts of the mountains subject to exposure received more precipitation. The temporal changes in the precipitation of the region has shown a general declining trend from 1975 up to 2010. Although the declined amount is more pronounced on the coastal parts, the situation is more critical in the inland parts with less precipitation. According to trend analysis results targeting the future, indications pertaining to the continuation of the declining precipitatıon trend have been observed Bu çalışmada Anadolu’nun ve ülkemizin batı kesimini kapsayan Ege Bölgesi’nde yağışın yüzeysel dağılım modellemesi gerçekleştirilmiştir. Yağışa 10’ar yıllık dönemler halinde Etkileşimli 3D Analizi, Coğrafi Ağırlıklı Regresyon, Radial Basis Function ve Quadratic Trend Analizleri uygulanmış ve yağış dağılış haritaları oluşturulmuştur. Bölgede yağışın dağılışı ve değişimi üzerinde plenater faktörlerin birinci derecede etkili olduğu sonucuna ulaşılmıştır. Yağışın lokal değişimleri üzerinde ise topoğrafik özellikler belirleyici olmuş, özellikle dağların kuzey kesimleri bakıya bağlı olarak daha fazla yağış aldığı tespit edilmiştir.

Key European Grid event to take place in Geneva

CERN Multimedia

2006-01-01

EGEE'06 is the main conference of the EGEE project, which is co-funded by the European Union and hosted by CERN. More than 90 partners all over Europe and beyond are working together in EGEE to provide researchers in both academia and industry with access to major computing resources, independent of their geographic location. The largest user community of the EGEE Grid is the High-Energy Physics community and in particular the LHC experiments, which are already making heavy use of the infrastructure to prepare for data taking. However, with the many new challenges faced by EGEE in its second phase that started in April this year, an even broader audience than at previous EGEE conferences is expected. In particular, a large number of related Grid projects will feature prominently in both plenary and parallel sessions during the 5 days of this event. Industry will also be well represented, highlighting the EGEE project's commitment to technology transfer to industry. CERN is the host of the conference, which i...

Eosinophilic gastritis (EG) and eosinophilic gastroenteritis (EGE) are chronic immune-mediated conditions of the digestive tract, which affect the stomach only, or the stomach and small intestines, respectively. Though these disorders are uncommon, they are being increasingly recognized and diagnosed. While health-related quality of life (HRQOL) has been evaluated in other eosinophilic gastrointestinal diseases, this study is the first to describe HRQOL impacts unique to EG/EGE. This study aims to qualitatively describe experiences of adults diagnosed with EG and EGE. We aim to identify impacts on HRQOL in this population in order to inform clinical care and assessment. Seven patients diagnosed with EG or EGE participated in semi-structured interviews assessing common domains of HRQOL. Four distinct themes emerged from qualitative analyses, which represent impacts to HRQOL: the psychological impact of the diagnosis, impact on social relationships, financial impact, and impact on the body. These generally improved over time and with effective treatment. This study demonstrated that patients with EG/EGE experience impacts to HRQOL, some of which differ from HRQOL of other eosinophilic gastrointestinal diseases. These results support the development of a disease-specific measure, or adaptation of an existing measure, to assess HRQOL in EG/EGE.

Appearance of microvascular obstruction on high resolution first-pass perfusion, early and late gadolinium enhancement CMR in patients with acute myocardial infarction

Directory of Open Access Journals (Sweden)

Redwood Simon

2009-08-01

Full Text Available Abstract Background The presence and extent of microvascular obstruction (MO after acute myocardial infarction can be measured by first-pass gadolinium-enhanced perfusion cardiovascular magnetic resonance (CMR or after gadolinium injection with early or late enhancement (EGE/LGE imaging. The volume of MO measured by these three methods may differ because contrast agent diffusion into the MO reduces its apparent extent over time. Theoretically, first-pass perfusion CMR should be the most accurate method to measure MO, but this technique has been limited by lower spatial resolution than EGE and LGE as well as incomplete cardiac coverage. These limitations of perfusion CMR can be overcome using spatio-temporal undersampling methods. The purpose of this study was to compare the extent of MO by high resolution first-pass k-t SENSE accelerated perfusion, EGE and LGE. Methods 34 patients with acute ST elevation myocardial infarction, treated successfully with primary percutaneous coronary intervention (PPCI, underwent CMR within 72 hours of admission. k-t SENSE accelerated first-pass perfusion MR (7 fold acceleration, spatial resolution 1.5 mm × 1.5 mm × 10 mm, 8 slices acquired over 2 RR intervals, 0.1 mmol/kg Gd-DTPA, EGE (1–4 minutes after injection with a fixed TI of 440 ms and LGE images (10–12 minutes after injection, TI determined by a Look-Locker scout were acquired. MO volume was determined for each technique by manual planimetry and summation of discs methodology. Results k-t SENSE first-pass perfusion detected more cases of MO than EGE and LGE (22 vs. 20 vs. 14, respectively. The extent of MO imaged by first-pass perfusion (median mass 4.7 g, IQR 6.7 was greater than by EGE (median mass 2.3 g, IQR 7.1, p = 0.002 and LGE (median mass 0.2 g, IQR 2.4, p = 0.0003. The correlation coefficient between MO mass measured by first-pass perfusion and EGE was 0.91 (p Conclusion The extent of MO following acute myocardial infarction appears larger on

The glycol ethers are an important and widely used class of solvents. Recent studies have demonstrated that ethylene glycol monomethyl ether (EGME), ethylene glycol dimethyl ether (EGdiME), ethylene glycol monoethyl ether (EGEE), and ethylene glycol monoethyl ether acetate (EGEEA) are teratogenic. Other studies have demonstrated that testicular atrophy or infertility follow treatment of males with EGME, ethylene glycol monomethyl ether acetate (EGMEA), EGEE, EGEEA, diethylene glycol dimethyl ether (diEGdiME), and diethylene glycol monoethyl ether (diEGEE). Experimental data are reviewed and structure-activity relationships are speculated upon.

It has been shown that female workers exposed to ethylene glycol ethers (EGEs) in the semiconductor industry have higher risks of spontaneous abortion, subfertility, and menstrual disturbances, and prolonged waiting time to pregnancy. To examine whether EGEs or other chemicals are associated with long menstrual cycles in female workers in the semiconductor manufacturing industry. Cross-sectional questionnaire survey during the annual health examination at a wafer manufacturing company in Taiwan in 1997. A three tiered exposure-assessment strategy was used to analyse the risk. A short menstrual cycle was defined to be a cycle less than 24 days and a long cycle to be more than 35 days. There were 606 valid questionnaires from 473 workers in fabrication jobs and 133 in non-fabrication areas. Long menstrual cycles were associated with workers in fabrication areas compared to those in non-fabrication areas. Using workers in non-fabrication areas as referents, workers in photolithography and diffusion areas had higher risks for long menstrual cycles. Workers exposed to EGEs and isopropanol, and hydrofluoric acid, isopropanol, and phosphorous compounds also showed increased risks of a long menstrual cycle. Exposure to multiple chemicals, including EGEs in photolithography, might be associated with long menstrual cycles, and may play an important role in a prolonged time to pregnancy in the wafer manufacturing industry; however, the prevalence in the design, possible exposure misclassification, and chance should be considered.

Shadows behind the computers

CERN Document Server

2007-01-01

EGEE organized a shadowing day to spur female students to take up careers in the IT field. Eleven female staff from CERN’s IT Department were kept under close surveillance last week, shadowed by female students from the Collège du Léman International School as part of the Enabling Grids for E-sciencE project Gender Action Plan. The shadowing day was aimed at inspiring young women to think of careers in information technology, by passing on the message that careers in science are open to both men and women and can be rewarding and fun. The students were given a tour of the ATLAS physics experiment and the CERN Computer Centre, as well as the opportunity for one-to-one interaction with CERN IT staff. Traditionally, fewer women work in the IT sector; women currently represent 21% of EGEE staff. The shadowing day was held as part of the EGEE Gender Action Plan, reflecting a commitment to reducing this gender gap. Other initiatives in...

Assessing the toxic effects of ethylene glycol ethers using Quantitative Structure Toxicity Relationship models

International Nuclear Information System (INIS)

Ruiz, Patricia; Mumtaz, Moiz; Gombar, Vijay

2011-01-01

Experimental determination of toxicity profiles consumes a great deal of time, money, and other resources. Consequently, businesses, societies, and regulators strive for reliable alternatives such as Quantitative Structure Toxicity Relationship (QSTR) models to fill gaps in toxicity profiles of compounds of concern to human health. The use of glycol ethers and their health effects have recently attracted the attention of international organizations such as the World Health Organization (WHO). The board members of Concise International Chemical Assessment Documents (CICAD) recently identified inadequate testing as well as gaps in toxicity profiles of ethylene glycol mono-n-alkyl ethers (EGEs). The CICAD board requested the ATSDR Computational Toxicology and Methods Development Laboratory to conduct QSTR assessments of certain specific toxicity endpoints for these chemicals. In order to evaluate the potential health effects of EGEs, CICAD proposed a critical QSTR analysis of the mutagenicity, carcinogenicity, and developmental effects of EGEs and other selected chemicals. We report here results of the application of QSTRs to assess rodent carcinogenicity, mutagenicity, and developmental toxicity of four EGEs: 2-methoxyethanol, 2-ethoxyethanol, 2-propoxyethanol, and 2-butoxyethanol and their metabolites. Neither mutagenicity nor carcinogenicity is indicated for the parent compounds, but these compounds are predicted to be developmental toxicants. The predicted toxicity effects were subjected to reverse QSTR (rQSTR) analysis to identify structural attributes that may be the main drivers of the developmental toxicity potential of these compounds.

Highlights: {yields} Effect of ethylene glycol ethers on diesel fuel properties. {yields} Effect of ethylene glycol ethers on diesel engine specific consumption and emissions. {yields} Blends with {<=}4 wt.% of oxygen do not change substantially diesel fuel quality. {yields} Blends with 1 and 2.5 wt.% of oxygen reduce CO and HC emissions, but not smoke. - Abstract: The effect of ethylene glycol ethers on both the diesel fuel characteristics and the exhaust emissions (CO, NO{sub x}, smoke and hydrocarbons) from a diesel engine was studied. The ethers used were monoethylene glycol ethyl ether (EGEE), monoethylene glycol butyl ether (EGBE), diethylene glycol ethyl ether (DEGEE). The above effect was studied in two forms: first by determining the modification of base diesel fuel properties by using blends with oxygen concentration around 4 wt.%, and second by determining the emission reductions for blends with low oxygen content (1 wt.%) and with 2.5 wt.% of oxygen content. The addition of DEGEE enhances base diesel fuel cetane number, but EGEE and EGBE decrease it. For concentrations of {>=}4 wt.% of oxygen, EGEE and diesel fuel can show immiscibility problems at low temperatures ({<=}0 {sup o}C). Also, every oxygenated compound, according to its boiling point, modifies the distillation curve at low temperatures and the distillate percentage increases. These compounds have a positive effect on diesel fuel lubricity, and slightly decrease its viscosity. Blends with 1 and 2.5 wt.% oxygen concentrations were used in order to determine their influence on emissions at both full and medium loads and different engine speeds. Generally, all compounds help to reduce CO, and hydrocarbon emissions, but not smoke. The best results were obtained for blends with 2.5 wt.% of oxygen. At this concentration, the additive efficiency in decreasing order was EGEE > DEGEE > EGBE for CO emissions and DGEE > EGEE > EGBE for hydrocarbon emissions. For NO{sub x}, both its behaviour and the

Grid attacks avian flu

During April, a collaboration of Asian and European laboratories analysed 300,000 possible drug components against the avian flu virus H5N1 using the EGEE Grid infrastructure. Schematic presentation of the avian flu virus.The distribution of the EGEE sites in the world on which the avian flu scan was performed. The goal was to find potential compounds that can inhibit the activities of an enzyme on the surface of the influenza virus, the so-called neuraminidase, subtype N1. Using the Grid to identify the most promising leads for biological tests could speed up the development process for drugs against the influenza virus. Co-ordinated by CERN and funded by the European Commission, the EGEE project (Enabling Grids for E-sciencE) aims to set up a worldwide grid infrastructure for science. The challenge of the in silico drug discovery application is to identify those molecules which can dock on the active sites of the virus in order to inhibit its action.

Casey, James; Cons, Lionel; Lapka, Wojciech; Paladin, Massimo; Skaburskas, Konstantin

2011-01-01

During the EGEE-III project operational tools such as SAM, Nagios, Gridview, the regional Dashboard and GGUS moved to a communication architecture based on ActiveMQ, an open-source enterprise messaging solution. LHC experiments, in particular ATLAS, developed prototypes of systems using the same messaging infrastructure, validating the system for their use-cases. In this paper we describe the WLCG messaging use cases and outline an improved messaging architecture based on the experience gained during the EGEE-III period. We show how this provides a solid basis for many applications, including the grid middleware, to improve their resilience and reliability.

Full Text Available Neste trabalho propõem-se o uso da distribuição Exponencial Geométrica Estendida (EGE como um modelo alternativo às distribuições comumente utilizadas tais como Gama, Weibull, Lognormal, entre outras, para a modelagem de dados de precipitação pluvial. Pouco explorada na literatura, a distribuição EGE tem se mostrado eficiente em diversos campos de pesquisa como biologia, demografia, confiabilidade de produtos eletrônicos e pode ser aplicada para analisar fenômenos meteorológicos. Proposta por Adamidis e colaboradores em 2005, uma de suas particularidades é que sua função de risco pode ser crescente ou decrescente. Outra característica importante é a facilidade em se obter diferentes níveis de probabilidade, sem a necessidade de recorrer a métodos numéricos. Testou-se o ajustamento da distribuição EGE para a estimação da precipitação pluvial total mensal de Presidente Prudente-SP. Os resultados mostraram que houve um bom ajuste do modelo para os dados ao serem comparados com outros modelos como Gama, Weibull e Lognormal, de acordo com o critério de informação de Akaike, o teste Kolmogorov-Smirnov e o teste Qui-quadrado ao nivel de 5% de significância. A partir do ajustamento da distribuição EGE aos dados, os estimadores dos parâmetros da distribuição foram obtidos através do método de máxima verossimilhança permitindo assim a estimação da precipitação pluvial total mensal para diferentes níveis de probabilidade.

Therapists and patients enjoy and benefit from interventions that use electronic games (EG) in health care and mental health settings, with a variety of diagnoses and therapeutic goals. We reviewed the use of electronic games designed specifically for a therapeutic purpose, electronic games for psychotherapy (EGP), also called serious games, and commercially produced games used as an adjunct to psychotherapy, electronic games for entertainment (EGE). Recent research on the benefits of EG in rehabilitation settings, EGP, and EGE indicates that electronic methods are often equivalent to more traditional treatments and may be more enjoyable or acceptable, at least to some consumers. Methodological concerns include the lack of randomized controlled trials (RCT) for many applications. Suggestions are offered for using EG in therapeutic practice.

Full Text Available The integration of wind power into power grid will bring some impacts on the multiple subjects of electric power system. Economic impacts of wind power integration on multiple subjects of China’s electric power system were quantitatively assessed from Quasi-public goods property perspective in this paper. Firstly, the Quasi-public goods property of transmission services provided by power grid corporations was elaborated. Secondly, the multiple subjects of China’s electric power system, which include electricity generation enterprises (EGEs, power grid corporations (PGCs, electricity consumers (ECs, and environment, were detailed analyzed. Thirdly, based on the OPF-based nodal price model and transmission service cost allocation model, the economic impact assessment model of wind power integration was built from Quasi-public goods property perspective. Then, the IEEE-24 bus system employed in this paper was introduced according to current status of China’s electric power system, and the modeling of wind turbine was also introduced. Finally, the simulation analysis was performed, and the economic impacts of wind power integration on EGEs, PGCs, ECs and Environment were calculated. The results indicate, from Quasi-public goods property perspective, the wind power integration will bring positive impacts on EGEs, PGCs and Environment, while negative impacts on ECs. The findings can provide references for power system managers, energy planners, and policy makers.

Full Text Available The Biblical principle of reformation challenges the Christian to question the traditional position of women and if necessary to change it, as well as to critically evaluate the various trends within the women's movement. It is stated that the generalizing use of the term feminism has become outdated, and should be replaced by differentiated terminology. The latter should be based on critical nuancing, with due regard to the view of history, the approach to sexuality/sex and the religious directedness of each specific trend or school of thought. Against the background of the sexism and traditionalism of male chauvinism , this article offers a prelim inary framework from which a number of fem inist and moderate trends within the women's movement can be identified. Within feminism a distinction is drawn between egalitarian and gynaecentric (neo-sexist trends. The moderate wing of the women's movement includes a humanist and a Christian approach, with androgynous and holistic views respectively as examples of these. Finally the author points out that the use of the Bible by feminist theologians and other representatives of the women's movement offers no guarantee for Scriptural viewpoints, and warns against generalizing judgments about proponents of women's rights.

The aim of the EGEE (Enabling Grids for E-Science in Europe) project is to create a reliable and dependable European Grid infrastructure for e-Science. The objective of the EGEE Middleware Re-engineering and Integration Research Activity is to provide robust middleware components, deployable on several platforms and operating systems, corresponding to the core Grid services for resource access, data management, information collection, authentication & authorization, resource matchmaking and brokering, and monitoring and accounting. For achieving this objective, we developed an architecture and design of the next generation Grid middleware leveraging experiences and existing components essentially from AliEn, EDG, and VDT. The architecture follows the service breakdown developed by the LCG ARDA group. Our strategy is to do as little original development as possible but rather re-engineer and harden existing Grid services. The evolution of these middleware components towards a Service Oriented Architecture ...

Recently a growing number of various applications have been quickly and successfully enabled on the Grid by the CERN Grid application support team. This allowed the applications to achieve and publish large-scale results in a short time which otherwise would not be possible. We present the general infrastructure, support procedures and tools that have been developed. We discuss the general patterns observed in supporting new applications and porting them to the EGEE environment. The CERN Grid application support team has been working with the following real-life applications: medical and particle physics simulation (Geant4, Garfield), satellite imaging and geographic information for humanitarian relief operations (UNOSAT), telecommunications (ITU), theoretical physics (Lattice QCD, Feynman-loop evaluation), Bio-informatics (Avian Flu Data Challenge), commercial imaging processing and classification (Imense Ltd.) and physics experiments (ATLAS, LHCb, HARP).

Sustainable support for WLCG through the EGI distributed infrastructure

International Nuclear Information System (INIS)

Antoni, Torsten; Bozic, Stefan; Reisser, Sabine

2011-01-01

Grid computing is now in a transition phase from development in research projects to routine usage in a sustainable infrastructure. This is mirrored in Europe by the transition from the series of EGEE projects to the European Grid Initiative (EGI). EGI aims at establishing a self-sustained grid infrastructure across Europe. The main building blocks of EGI are the national grid initiatives in the participating countries and a central coordinating institution (EGI.eu). The middleware used is provided by consortia outside of EGI. Also the user communities are organized separately from EGI. The transition to a self-sustained grid infrastructure is aided by the EGI-InSPIRE project, aiming at reducing the project-funding needed to run EGI over the course of its four year duration. Providing user support in this framework poses new technical and organisational challenges as it has to cross the boundaries of various projects and infrastructures. The EGI user support infrastructure is built around the Gobal Grid User Support system (GGUS) that was also the basis of user support in EGEE. Utmost care was taken that during the transition from EGEE to EGI support services which are already used in production were not perturbed. A year into the EGI-InSPIRE project, in this paper we would like to present the current status of the user support infrastructure provided by EGI for WLCG, new features that were needed to match the new infrastructure, issues and challenges that occurred during the transition and give an outlook on future plans and developments.

Distributed computing harnesses the power of thousands of computers within organisations or over the Internet. In order to tackle global health problems, several groups of researchers have begun to use this approach to exceed by far the computing power of a single lab. This event illustrates how companies, research institutes and the general public are contributing their computing power to these efforts, and what impact this may have on a range of world health issues. Grids for neglected diseases Vincent Breton, CNRS/EGEE This talk introduces the topic of distributed computing, explaining the similarities and differences between Grid computing, volunteer computing and supercomputing, and outlines the potential of Grid computing for tackling neglected diseases where there is little economic incentive for private R&D efforts.

Smith, A C

2007-01-01

The LHCb experiment being built to utilize CERN’s flagship Large Hadron Collider will generate data to be analysed by a community of over 600 physicists worldwide. DIRAC, LHCb’s Workload and Data Management System, facilitates the use of underlying EGEE Grid resources to generate, process and analyse this data in the distributed environment. The Data Management System, presented here, provides real-time, data-driven distribution in accordance with LHCb’s Computing Model. The data volumes produced by the LHC experiments are unprecedented, rendering individual institutes and even countries, unable to provide the computing and storage resources required to make full use of the produced data. EGEE Grid resources allow the processing of LHCb data possible in a distributed fashion and LHCb’s Computing Model is based on this approach. Data Management in this environment requires reliable and high-throughput transfer of data, homogeneous access to storage resources and the cataloguing of data replicas, all of...

High liquid fuel yielding biofuel processes and a roadmap for the future transportation

Science.gov (United States)

Singh, Navneet R.

In a fossil-fuel deprived world when crude oil will be scarce and transportation need cannot be met with electricity and transportation liquid fuel must be produced, biomass derived liquid fuels can be a natural replacement. However, the carbon efficiency of the currently known biomass to liquid fuel conversion processes ranges from 35-40%, yielding 90 ethanol gallon equivalents (ege) per ton of biomass. This coupled with the fact that the efficiency at which solar energy is captured by biomass (hydrodeoxygenation is proposed which can achieve liquid fuel yield of 215 ege/ton consuming 0.11 kg hydrogen per liter of oil. Due to the lower hydrogen consumption of the H2Bioil process, synergistically integrated transition pathways are feasible where hot syngas derived from coal gasification (H2Bioil-C) or a natural gas reformer (H 2Bioil-NG) is used to supply the hydrogen and process heat for the biomass fast-hydropyrolysis/hydrodeoxygenation. Another off-shoot of the H2Bioil process is the H2Bioil-B process, where hydrogen required for the hydropyrolysis is obtained from gasification of a fraction of the biomass. H2Bioil-B achieves the highest liquid fuel yield (126-146 ege/ton of biomass) reported in the literature for any self-contained conversion of biomass to biofuel. Finally, an integration of the H2Bioil process with the H2CAR process is suggested which can achieve 100% carbon efficiency (330 ege/ton of biomass) at the expense of 0.24 kg hydrogen/liter of oil. A sun-to-fuel efficiency analysis shows that extracting CO2 from air and converting it to liquid fuel is at least two times more efficient than growing dedicated fuel crops and converting them to liquid fuel even for the highest biomass growth rates feasible by algae. This implies that liquid fuel should preferably be produced from sustainably available waste (SAW) biomass first and if the SAW biomass is unable to meet the demand for liquid fuel, then, CO2 should be extracted from air and converted to

2004-01-01

In September 2003 the first LCG-1 service was put into production at most of the large Tier 1 sites and was quickly expanded up to 30 Tier 1 and Tier 2 sites by the end of the year. Several software upgrades were made and the LCG-2 service was put into production in time for the experiment data challenges that began in February 2004 and continued for several months. In particular LCG-2 introduced transparent access to mass storage and managed disk-only storage elements, and a first release of the Grid File Access library. Much valuable experience was gained during the data challenges in all aspects from the functionality and use of the middleware, to the deployment, maintenance, and operation of the services at many sites. Based on this experience a program of work to address the functional and operational issues is being implemented. The goal is to focus on essential areas such as data management and to build by the end of 2004 a basic grid system capable of handling the basic needs of LHC c...

With the growth of genome databases and the implied complexity for processing such information within bioinformatics research, there is a need for computing power and massive storage facilities which can be provided by Grid infrastructures. EMBOSS is a free Open Source sequence analysis package specially developed for the needs of the bioinformatics and molecular biology user community. This work describes the deployment of EMBOSS over the EELA and EGEE Grids, both gLite middle ware-based infrastructures. This work is focused on rewriting the I/O EMBOSS libraries (AJAX) to use the GFAL from the LCG/EGEE middle ware. This library allows the use of files registered on the catalog service which are contained in the storage elements of a Grid. Submitting a job into a Grid is not an intuitive task. This work also describes an ad hoc mechanism to allow bioinformaticians to concentrate on the EMBOSS command, instead of acquiring advanced knowledge about Grid usage. The results obtained so far demonstrate the functionality of GrEMBOSS, and represent an efficient and viable alternative for gridifying other bioinformatics applications. (Author)

The purpose of this study is to analyze the causality, whether the money supply affects inflation or vice versa. Analytical tool used is unit root test, integration degree test, causality test with granger causality technique and cointegration approach. The result of unit root test data is not stationary, after test of stationary data continued at level 1 (first difference. The result of granger causality test with lag 12 indicates that the money supply has an effect on inflation rate in Indonesia, and vice versa means there is a mutual relationship. And based on Johanson's cointegration test shows that mutual cointegration means having long-term equilibrium relationship as desired by the theory.

2010-01-01

A dynamic and reliable system for installing the ATLAS software releases on Grid sites is crucial to guarantee the timely and smooth start of ATLAS production and reduce its failure rate. In this paper, we discuss the issues encountered in the previous software installation system, and introduce the new approach, which is built upon the new development in the areas of the ATLAS workload management system (PanDA), and software package management system (pacman). It is also designed to integrate with the EGEE ATLAS software installation framework. In the new system, ATLAS software releases are packaged as pacball, a uniquely identifiable and reproducible self-installing data file. The distribution of pacballs to remote sites is managed by ATLAS data management system (DQ2) and PanDA server. The installation on remote sites is automatically triggered by the PanDA pilot jobs. The installation job payload connects to a central ATLAS software installation portal, making the information of installation status easily accessible across OSG and EGEE Grids. The issues encountered in running the new system in production, and our future plan for improvement, will also be discussed.

2008-01-01

The benefits that the Pre-Production Service (PPS) can offer to VOs and new users will be shown. Current PPS processes will be described so they have a better understanding of the PPS environment. PPS offers a proper place where VOs can test their applications and check their compatibility with upcoming middleware releases. PPS could help VOs improve their applications and at the same time, VOs would be helping PPS to produce better tested middleware releases that would go into Production (PROD) Currently a well-defined set of procedures is followed in PPS, beginning with the pre-deployment activity and finishing with the approval of a new middleware release that can go into PROD. The PPS Coordination Team takes care of supervising all these steps, mainly trying to spot possible bugs in the middleware before it goes into PROD. Unfortunately, VO contribution in this part of the deployment is currently very limited and the PPS team does not have a full feedback from these important groups. One of the problems i...

Gadhia, Hitesh Kumar; Kotzab, Herbert; Prockl, Günter

2011-01-01

This paper examines the internationalization level of the world’s largest container shipping companies by examining their port networks. The results of our analysis show that only three of the nineteen companies could be considered as being truly ‘International’ and service the ‘lion’s share......’ of the major and minor ports distributed across the globe. The port networks of the other companies in our survey, whilst having individualized features, shared common characteristics. Guided by the ‘Uppsala Model of Incremental Internationalization’ (Johanson and Vahlne, 1977), we were able to identify four...... internationalization levels of a container shipping company that are indicated by their port network. We argue that the port network plays an additional role as it contributes to the internationalization level of the container shipping companies. This is important because the internationalization level affects...

Ascites in a Young Woman: A Rare Presentation of Eosinophilic Gastroenteritis

Directory of Open Access Journals (Sweden)

Carina Santos

2018-01-01

Full Text Available Introduction. Eosinophilic gastroenteritis (EGE is a rare idiopathic disease that can affect one or more organs of the digestive tract. It has an estimated incidence of 1–20 cases per 100,000 patients. Klein et al. classified EGE into 3 subtypes: predominant mucosal, muscular, or subserosal. Clinical Case. We report a case of a 32-year-old woman, who presented with diffuse abdominal pain, nausea, postprandial infarction, diarrhea, and moderate ascites of three-week evolution. The rest of physical examination did not show alterations. The past medical history was unremarkable. Laboratory test results revealed peripheral blood eosinophilia. Abdominal CT scan revealed diffuse and concentric parietal thickening of the distal 2/3 of esophagus, moderate volume ascites, and small bowel wall thickening and distension on the left quadrants. The paracentesis revealed 93.3% of eosinophils. The colon biopsies evidenced an increase in the number of eosinophils. Secondary causes of eosinophilia were excluded. The patient was treated with oral prednisolone 40 mg/day with immediate clinical and analytical improvement. Conclusion. Eosinophilic gastroenteritis is a rare condition with a nonspecific and highly variable clinical presentation, which requires a high level of clinical suspicion. It is a diagnosis of exclusion. Secondary causes of eosinophilia such as intestinal tuberculosis, parasitosis, and malignant neoplasms should be excluded.

Ventilator-associated pneumonia (VAP) is defined as pneumonia occuring in any period of mechanical ventilation. There is no optimal diagnostic method in current use and in this study we aimed to compare two non-invasive diagnostic methods used in diagnosis of VAP in children. This prospective study was conducted in 8 bedded Pediatric Intensive Care Unit at Ege University Children´s Hospital. Endotracheal aspiration (ETA) and non-bronchoscopic bronchoalveolar lavage (BAL) were performed in case of developing VIP after 48 hours of ventilation. Quantitative cultures were examined in Ege University Department of Diagnostic Microbiology, Bacteriology Laboratory. Fourty-one patients were enrolled in the study. The mean age of study subjects was 47.2±53.6 months. A total of 28 in 82 specimens taken with both methods were negative/negative; 28 had positive result with ETA and a negative result with non-bronchoscopic BAL and both results were negative in 26 specimens. There were no patients whose respiratory specimen culture was negative with ETA and positive with non-bronchoscopic BAL. These results imply that there is a significant difference between two diagnostic methods (p VAP; therefore, ETA results were compared with this method. ETA's sensitivity, specificity, negative and positive predictive values were 100%, 50%, 100% and 48% respectively. The study revealed the ease of usability and the sensitivity of non-bronchoscopic BAL, in comparison with ETA.

Experience with the gLite workload management system in ATLAS Monte Carlo production on LCG

International Nuclear Information System (INIS)

Campana, S; Sciaba, A; Rebatto, D

2008-01-01

The ATLAS experiment has been running continuous simulated events production since more than two years. A considerable fraction of the jobs is daily submitted and handled via the gLite Workload Management System, which overcomes several limitations of the previous LCG Resource Broker. The gLite WMS has been tested very intensively for the LHC experiments use cases for more than six months, both in terms of performance and reliability. The tests were carried out by the LCG Experiment Integration Support team (in close contact with the experiments) together with the EGEE integration and certification team and the gLite middleware developers. A pragmatic iterative and interactive approach allowed a very quick rollout of fixes and their rapid deployment, together with new functionalities, for the ATLAS production activities. The same approach is being adopted for other middleware components like the gLite and CREAM Computing Elements. In this contribution we will summarize the learning from the gLite WMS testing activity, pointing out the most important achievements and the open issues. In addition, we will present the current situation of the ATLAS simulated event production activity on the EGEE infrastructure based on the gLite WMS, showing the main improvements and benefits from the new middleware. Finally, the gLite WMS is being used by many other VOs, including the LHC experiments. In particular, some statistics will be shown on the CMS experience running WMS user analysis via the WMS

Optimisation and validation of a 3D reconstruction algorithm for single photon emission computed tomography by means of GATE simulation platform

International Nuclear Information System (INIS)

El Bitar, Ziad

2006-12-01

Although time consuming, Monte-Carlo simulations remain an efficient tool enabling to assess correction methods for degrading physical effects in medical imaging. We have optimized and validated a reconstruction method baptized F3DMC (Fully 3D Monte Carlo) in which the physical effects degrading the image formation process were modelled using Monte-Carlo methods and integrated within the system matrix. We used the Monte-Carlo simulation toolbox GATE. We validated GATE in SPECT by modelling the gamma-camera (Philips AXIS) used in clinical routine. Techniques of threshold, filtering by a principal component analysis and targeted reconstruction (functional regions, hybrid regions) were used in order to improve the precision of the system matrix and to reduce the number of simulated photons as well as the time consumption required. The EGEE Grid infrastructures were used to deploy the GATE simulations in order to reduce their computation time. Results obtained with F3DMC were compared with the reconstruction methods (FBP, ML-EM, MLEMC) for a simulated phantom and with the OSEM-C method for the real phantom. Results have shown that the F3DMC method and its variants improve the restoration of activity ratios and the signal to noise ratio. By the use of the grid EGEE, a significant speed-up factor of about 300 was obtained. These results should be confirmed by performing studies on complex phantoms and patients and open the door to a unified reconstruction method, which could be used in SPECT and also in PET. (author)

Worker nodes on the grid exhibit great diversity, making it difficult to offer uniform processing resources. A pilot job architecture, which probes the environment on the remote worker node before pulling down a payload job, can help. Pilot jobs become smart wrappers, preparing an appropriate environment for job execution and providing logging and monitoring capabilities. PanDA (Production and Distributed Analysis), an ATLAS and OSG workload management system, follows this design. However, in the simplest (and most efficient) pilot submission approach of identical pilots carrying the same identifying grid proxy, end-user accounting by the site can only be done with application-level information (PanDA maintains its own end-user accounting), and end-user jobs run with the identity and privileges of the proxy carried by the pilots, which may be seen as a security risk. To address these issues, we have enabled PanDA to use gLExec, a tool provided by EGEE which runs payload jobs under an end-user's identity. End-user proxies are pre-staged in a credential caching service, MyProxy, and the information needed by the pilots to access them is stored in the PanDA DB. gLExec then extracts from the user's proxy the proper identity under which to run. We describe the deployment, installation, and configuration of gLExec, and how PanDA components have been augmented to use it. We describe how difficulties were overcome, and how security risks have been mitigated. Results are presented from OSG and EGEE Grid environments performing ATLAS analysis using PanDA and gLExec.

The Grid community uses two well-established registration services, which allow users to be authenticated under the auspices of Virtual Organizations (VOs). The Virtual Organization Membership Service (VOMS), developed in the context of the Enabling Grid for E-sciencE (EGEE) project, is an Attribute Authority service that issues attributes expressing membership information of a subject within a VO. VOMS allows to partition users in groups, assign them roles and free-form attributes which are then used to drive authorization decisions. The VOMS administrative application, VOMS-Admin, manages and populates the VOMS database with membership information. The Virtual Organization Management Registration Service (VOMRS), developed at Fermilab, extends the basic registration and management functionalities present in VOMS-Admin. It implements a registration workflow that requires VO usage policy acceptance and membership approval by administrators. VOMRS supports management of multiple grid certificates, and handling users' request for group and role assignments, and membership status. VOMRS is capable of interfacing to local systems with personnel information (e.g. the CERN Human Resource Database) and of pulling relevant member information from them. VOMRS synchronizes the relevant subset of information with VOMS. The recent development of new features in VOMS-Admin raises the possibility of rationalizing the support and converging on a single solution by continuing and extending existing collaborations between EGEE and OSG. Such strategy is supported by WLCG, OSG, US CMS, US Atlas, and other stakeholders worldwide. In this paper, we will analyze features in use by major experiments and the use cases for registration addressed by the mature single solution.

Generally radiological protection has focused on human. But International Commission on Radiological Protection (ICRP) requires the effect data of ionizing radiation on nonhuman biota for the radiological protection of the environment. The choice of a melania snail as a model for environmental biomonitoring of radiation genotoxicity took into account that invertebrates represent one of aquatic species. The comet assay or single cell gel electrophoresis (SCGE) assay, first introduced by Ostling and Johanson, was used to detect DNA single strand breaks and to investigate the application of this technique as a tool for aquatic biomonitoring. Comet assay offers considerable advantages over some other assays used in DNA damage detection, such as chromosomal aberrations, sister chromatid Exchange and the micronucleus test, since there is no need for cells to be in a dividing state. Other advantages are its rapidity, relatively low coast, and wide applicability to virtually any nucleated cell type. In this study, we evaluated DNA damage in cells of Semisulcospira libertina after irradiation with {sup 60}Co gamma radiation by using the comet assay

2010-01-01

In this paper we describe the architecture and operation of the Real Time Monitor (RTM), developed by the Grid team in the HEP group at Imperial College London. This is arguably the most popular dissemination tool within the EGEE [1] Grid. Having been used, on many occasions including GridFest and LHC inauguration events held at CERN in October 2008. The RTM gathers information from EGEE sites hosting Logging and Bookkeeping (LB) services. Information is cached locally at a dedicated server at Imperial College London and made available for clients to use in near real time. The system consists of three main components: the RTM server, enquirer and an apache Web Server which is queried by clients. The RTM server queries the LB servers at fixed time intervals, collecting job related information and storing this in a local database. Job related data includes not only job state (i.e. Scheduled, Waiting, Running or Done) along with timing information but also other attributes such as Virtual Organization and Computing Element (CE) queue - if known. The job data stored in the RTM database is read by the enquirer every minute and converted to an XML format which is stored on a Web Server. This decouples the RTM server database from the client removing the bottleneck problem caused by many clients simultaneously accessing the database. This information can be visualized through either a 2D or 3D Java based client with live job data either being overlaid on to a 2 dimensional map of the world or rendered in 3 dimensions over a globe map using OpenGL.

The recent explosion of recorded digital data and its processed derivatives threatens to overwhelm researchers when analysing their experimental data or looking up data items in archives and file systems. While current hardware developments allow the acquisition, processing and storage of hundreds of terabytes of data at the cost of a modern sports car, the software systems to handle these data are lagging behind. This problem is very general and is well recognized by various scientific communities; several large projects have been initiated, e.g., DATAGRID/EGEE {http://www.eu-egee.org/} federates compute and storage power over the high-energy physical community, while the international astronomical community is building an Internet geared Virtual Observatory {http://www.euro-vo.org/pub/} (Padovani 2006) connecting archival data. These large projects either focus on a specific distribution aspect or aim to connect many sub-communities and have a relatively long trajectory for setting standards and a common layer. Here, we report first light of a very different solution (Valentijn & Kuijken 2004) to the problem initiated by a smaller astronomical IT community. It provides an abstract scientific information layer which integrates distributed scientific analysis with distributed processing and federated archiving and publishing. By designing new abstractions and mixing in old ones, a Science Information System with fully scalable cornerstones has been achieved, transforming data systems into knowledge systems. This break-through is facilitated by the full end-to-end linking of all dependent data items, which allows full backward chaining from the observer/researcher to the experiment. Key is the notion that information is intrinsic in nature and thus is the data acquired by a scientific experiment. The new abstraction is that software systems guide the user to that intrinsic information by forcing full backward and forward chaining in the data modelling.

Evidence of a novel aggrecan-degrading activity in cartilage: Studies of mice deficient in both ADAMTS-4 and ADAMTS-5.

To characterize aggrecan catabolism and the overall phenotype in mice deficient in both ADAMTS-4 and ADAMTS-5 (TS-4/TS-5 Delta-cat) activity. Femoral head cartilage from the joints of TS-4/TS-5 Delta-cat mice and wild-type mice were cultured in vitro, and aggrecan catabolism was stimulated with either interleukin-1alpha (IL-1alpha) or retinoic acid. Total aggrecan release was measured, and aggrecanase activity was examined by Western blotting using neoepitope antibodies for detecting cleavage at EGE 373-374 ALG, SELE 1279-1280 GRG, FREEE 1467-1468 GLG, and AQE 1572-1573 AGEG. Aggrecan catabolism in vivo was examined by Western blotting of cartilage that had been extracted immediately ex vivo. TS-4/TS-5 Delta-cat mice were viable, fertile, and phenotypically normal. TS-4/TS-5 Delta-cat cartilage explants did not release aggrecan in response to IL-1alpha, and there was no detectable increase in aggrecanase neoepitopes. TS-4/TS-5 Delta-cat cartilage explants released aggrecan in response to retinoic acid. There was no retinoic acid-stimulated cleavage at either EGE 373-374 ALG or AQE 1572-1573 AGEG. There was a low level of cleavage at SELE 1279-1280 GRG and major cleavage at FREEE 1467-1468 GLG. Ex vivo, cleavage at FREEE 1467-1468 GLG was substantially reduced, but still present, in TS-4/TS-5 Delta-cat mouse cartilage compared with wild-type mouse cartilage. An aggrecanase other than ADAMTS-4 and ADAMTS-5 is expressed in mouse cartilage and is up-regulated by retinoic acid but not IL-1alpha. The novel aggrecanase appears to have different substrate specificity from either ADAMTS-4 or ADAMTS-5, cleaving E-G bonds but not E-A bonds. Neither ADAMTS-4 nor ADAMTS-5 is required for normal skeletal development or aggrecan turnover in cartilage.

Our objective was to evaluate the serologic positivity of cornea donors and microbiologic positivity of cornea storage media at the Ege University Tissue and Cornea Bank, Izmir, Turkey. We retrospectively investigated the serologic blood sample and microbiological culture media analysis results of all cornea donors at Ege University Tissue and Cornea Bank between 2007 and 2015 with reference to age, sex, and cause of death of each donor. Mean age of the 955 deceased donors was 43.19 ± 15.89 years (range, 2-65 y). The mean postmortem time to blood sample removal and excision of the cornea tissue was 8.4 hours (range, 4-12 h). Serologic analyses showed that 855 donors (89.5%) were seronegative. The remaining donors were seropositive for hepatitis B (54 donors; 5.7%), human immunodeficiency (27 donors; 2.8%), hepatitis C (14 donors; 1.5%), and syphilis (5 donors; 0.5%) virus infections. Microbiologic analyses of the storage media were negative, with no microorganisms shown in 855 samples (89.5%). Candida species (32 donors; 3.4%), Escherichia coli (14 donors; 1.5%), Pseudomonas aeruginosa (11 donors; 1.2%), methicillin-resistant Staphylococcus aureus (11 donors; 1.2%), Enterobacter species (11 donors; 1.2%), Klebsiella pneumoniae (7 donors; 0.7%), Acinetobacter baumannii (6 donors; 0.6%), Proteus species (5 donors; 0.5%), and Corynebacterium species (3 donors; 0.3%) were the detected microorganisms in the infected storage media. False-positive serologic results among cornea donors were high. The incidence of false-positive results might be decreased by earlier blood removal from deceased donors and testing of all potential donors in intensive care units. Although rare, endophthalmitis after keratoplasty might be a devastating problem. In addition to serologic testing, microbiologic analyses of cornea storage media before transplant may be an effective way to prevent postoperative infectious complications.

Full Text Available Nowadays, the increase in research projects at universities requires high-computing and mass-storage equipment, creating the need for having a supercomputing infrastructure. This work attempts to find a solution to the storage problems that arise in the different research groups at universities. Massive-storage infrastructures, which use a file system compatible with EGEE middleware, are implemented, taking advantage of the storage space left by working nodes. This should offer a very low-price solution. Additionally, a cluster with fundamental Grid services is created and thus integrated to the intercontinental infrastructure of EELA-2, establishing a platform for distributed computing and storage intended for the scientific community at Universidad Industrial de Santander.

In this paper we present the Experiment Dashboard monitoring system, which is currently in use by four Large Hadron Collider (LHC) experiments. The goal of the Experiment Dashboard is to monitor the activities of the LHC experiments on the distributed infrastructure, providing monitoring data from the virtual organization (VO) and user perspectives. The LHC experiments are using various Grid infrastructures (LCG/EGEE, OSG, NDGF) with correspondingly various middleware flavors and job submission methods. Providing a uniform and complete view of various activities like job processing, data movement and publishing, access to distributed databases regardless of the underlying Grid flavor is the challenging task. In this paper we will describe the Experiment Dashboard concept, its framework and main monitoring applications

[Overuse injury syndromes of the knee].

Pećina, M; Bojanić, I; Haspl, M

2001-12-01

Overuse injuries are frequent in the knee joint. The reason for this is that the knee joint is engaged in all sports activities. Furthermore, the joint area has numerous attachment points for muscles and tendons and numerous bursae. Another reason is that the specific joint between the patella and femur (patellofemoral joint) constitutes a part of the knee joint. Speaking in general terms, all overuse injuries in the knee joint can be divided in four groups according to the aspect: anterior aspect--patellofemoral pain syndrome, patellar tendinitis (jumper's knee), Osgood-Schlatter disease, Sinding Larson Johanson disease, stress fracture of the patella, fat pad syndrome; medial aspect--plica syndrome, semimembranosus tendinitis, pes anserinus tendinitis (bursitis), breaststroker's knee, medial retinaculitis; lateral aspect--Iliotibial band friction syndrome (runner's knee), Popliteal Tendinitis, Bicipital tendinitis; posterior aspect--fabellitis, medial gastrocnemius strain. There are numerous possible reasons for pain caused by overuse injuries around the knee joint, but two are the most frequent: patellar tendinitis (jumper's knee) and Iliotibial band friction syndrome (runner's knee). This paper gives a brief overview of overuse injuries of the knee joint including their definition, anatomy, aetiology, clinical symptoms and signs, and non-operative and surgical treatment.

Full Text Available A wealth of research has addressed the internationalization of firms using different theories and conceptual perspectives. This paper examines the extant research on internationalization specifically delving into seven streams of research: Market Power, Evolutionary Model, Internalization & Transaction Cost, Eclectic Paradigm, Resource-Based View, Institutional and International New Ventures & Born Global. Methodologically we conduct a bibliometric review in six leading journals recognized for publishing International Business (IB research, during a forty one year period, from 1970 to 2010. Using citations and co-citations analyses on a sample of 1,459 articles, we sought to better understand the internationalization approaches and how they are interconnected, by examining its growth over time, the most used approaches, the works that have had the greatest impact, and the intellectual interconnections among authors. We conclude that there is no dominant approach in International Business research, albeit the Evolutionary Model has been the most cited - in almost 26% of the extant research, specially the paper– “The internationalization process of the firm: A model of knowledge development and increasing foreign market commitment”, by Johanson and Vahlne (1977. We present a broad discussion and point out limitations and directions for future research.

VAMDC - The Virtual Atomic and Molecular Data Centre: A New Era in Database Collaboration

International Nuclear Information System (INIS)

Mason, N.J.

2011-01-01

Atomic and molecular data (A and M) are of critical importance in developing models of radiation chemistry including track structures. Currently these vital and fundamental A and M data resources are highly fragmented and only available through a variety of often poorly documented interfaces. The Virtual Atomic and Molecular Data Centre (VAMDC) is an EU funded e-infrastructure (www.vamdc.eu) that aims to provide the scientific community with access to a comprehensive, federated set of Atomic and Molecular (A and M) data. These structures have been created by initiatives such as the Euro-VO (http://www.euro-vo.org) and EGEE (Enabling Grids for E-sciencE, (http://www.eu-egee.org/). VAMDC will be built upon existing A and M databases. It has the specific aim of creating an infrastructure that on the one hand can directly extract data from the existing depositories while on the other hand is sufficiently flexible to be tuned to the needs of a wide variety of users from academic, governmental, industrial communities or even the general public. Central to VAMDC is the task of overcoming the current fragmentation of the A and M database community. VAMDC will alleviate this by: - developing the largest and most comprehensive atomic and molecular e-infrastructure to be shared, fed and expanded by A and M scientists; - providing a major distributed infrastructure which can be accessed, referenced and exploited by the wider research community. In fulfilling these aims, the VAMDC project will organise a series of Networking Activities (NAs). NAs are specifically aimed at: Engaging data providers; Coordinating activities among existing database providers; Ascertaining and responding to the needs of different user communities; Providing training and awareness of the VAMDC across the international A and M community and other use communities such as the radiation chemistry community. In this talk I will therefore outline the aims, methodology and mechanisms of the VAMDC project

Food powders flowability characterization: theory, methods, and applications.

Juliano, Pablo; Barbosa-Cánovas, Gustavo V

2010-01-01

Characterization of food powders flowability is required for predicting powder flow from hoppers in small-scale systems such as vending machines or at the industrial scale from storage silos or bins dispensing into powder mixing systems or packaging machines. This review covers conventional and new methods used to measure flowability in food powders. The method developed by Jenike (1964) for determining hopper outlet diameter and hopper angle has become a standard for the design of bins and is regarded as a standard method to characterize flowability. Moreover, there are a number of shear cells that can be used to determine failure properties defined by Jenike's theory. Other classic methods (compression, angle of repose) and nonconventional methods (Hall flowmeter, Johanson Indicizer, Hosokawa powder tester, tensile strength tester, powder rheometer), used mainly for the characterization of food powder cohesiveness, are described. The effect of some factors preventing flow, such as water content, temperature, time consolidation, particle composition and size distribution, is summarized for the characterization of specific food powders with conventional and other methods. Whereas time-consuming standard methods established for hopper design provide flow properties, there is yet little comparative evidence demonstrating that other rapid methods may provide similar flow prediction.

INTERNATIONALIZATION STRATEGIES OF EMERGING COMPANIES: A COMPARATIVE STUDY OF BRAZILIAN CASES

Full Text Available Over the last decade, interest has picked up as to emerging economies and their companies. This recent movement does not imply that previous theories and models are no longer applicable, however, one must analyze, in a broader comprehensive manner, a series of specific context factors and those concerning the management of this kind of company. Therefore, this paper analyzed the internationalization strategies adopted by six Brazilian companies before a set of internationalization models. A qualitative research approach was employed and in-depth interviews were conducted with corporate management level professionals. Companies were divided into three groups according to internationalization times (Group I – over ten years, Group II - between five and ten years, and Group III – under five years. Observations indicated that for Groups I and III companies the product lifecycle (Vernon, 1966 and 1979 and the eclectic paradigm (Dunning, 1980, 1988 and 2000 economic models support justifying internationalization motivations for companies’ internalization whilst the Uppsala model (Johanson and VAHLNE, 1979, 2009, at least in part explains, choice decisions concerning a few countries. As to Group II companies, the product lifecycle model is not the underlying motivation for internationalization, choices being more closely related to sector opportunities and the characteristics of both products and services.

Over the last two decades, several new methodologies for the detection of DNA damage have been developed. The comet assay is currently used in different areas of biological sciences to detect DNA damage. The comet assay, also called the single cell gel electrophoresis (SCGE) was first introduced by Ostling and Johanson as a microelectrophoretic technique for the direct visualization of DNA damage in individual cells. The comet assay, due to its simplicity, sensitivity and need of a few cells, is ideal as a short-term genotoxicity test. The comet assay can theoretically be applied to every type of eukaryotic cell, including plant cells. Plants are very useful as monitors of genetic effects caused by pollution in the atmosphere, water and soil. Although the genotoxic effects detected by Tradescantia tests cannot be associated with mutagenesis or even carcinogenesis in humans, these bioassays are very useful tools for screening the mutagenic potential in the environment. Experiments were conducted to study the genotoxic effects of ionizing radiations on the genome integrity, particularly of Tradescantia. The increasingly frequent use of Tradescantia as a sensitive environmental bioindicator of genotoxic effects. This study was designed to assess the genotoxicity of ionizing radiation using Tradescnatia-comet assay

Ten years of European Grids: What have we learnt?

International Nuclear Information System (INIS)

Burke, Stephen

2011-01-01

The European DataGrid project started in 2001, and was followed by the three phases of EGEE and the recent transition to EGI. This paper discusses the history of both middleware development and Grid operations in these projects, and in particular the impact on the development of the LHC Computing Grid. It considers to what extent the initial ambitions have been realised, which aspects have been successful and what lessons can be derived from the things which were less so, both in technical and sociological terms. In particular it considers the middleware technologies used for data management, workload management, information systems and security, and the difficulties of operating a highly distributed worldwide production infrastructure, drawing on practical experience with many aspects of the various Grid projects over the last decade.

Medical image registration is pre-processing needed for many medical image analysis procedures. A very large number of registration algorithms are available today, but their performance is often not known and very difficult to assess due to the lack of gold standard. The Bronze Standard algorithm is a very data and compute intensive statistical approach for quantifying registration algorithms accuracy. In this paper, we describe the Bronze Standard application and we discuss the need for grids to tackle such computations on medical image databases. We demonstrate MOTEUR, a service-based workflow engine optimized for dealing with data intensive applications. MOTEUR eases the enactment of the Bronze Standard and similar applications on the EGEE production grid infrastructure. It is a generic workflow engine, based on current standards and freely available, that can be used to instrument legacy application code at low cost.

A system to run Monte Carlo simulations on a Grid environment is presented. The architectural design proposed uses the current resources of the MAGIC Virtual Organization on EGEE and can be easily generalized to support the simulation of any similar experiment, such as that of the future European planned project, the Cherenkov Telescope Array. The proposed system is based on a Client/Server architecture, and provides the user with a single access point to the simulation environment through a remote graphical user interface, the Client. The Client can be accessed via web browser, using web service technology, with no additional software installation on the user side required. The Server processes the user request and uses a database for both data catalogue and job management inside the Grid. The design, first production tests and lessons learned from the system will be discussed here.

GStat 2.0: Grid Information System Status Monitoring

CERN Document Server

Field, L; Tsai, M; CERN. Geneva. IT Department

2010-01-01

Grid Information Systems are mission-critical components in today's production grid infrastructures. They enable users, applications and services to discover which services exist in the infrastructure and further information about the service structure and state. It is therefore important that the information system components themselves are functioning correctly and that the information content is reliable. Grid Status (GStat) is a tool that monitors the structural integrity of the EGEE information system, which is a hierarchical system built out of more than 260 site-level and approximately 70 global aggregation services. It also checks the information content and presents summary and history displays for Grid Operators and System Administrators. A major new version, GStat 2.0, aims to build on the production experience of GStat and provides additional functionality, which enables it to be extended and combined with other tools

Adaptively detecting changes in Autonomic Grid Computing

KAUST Repository

Zhang, Xiangliang

2010-10-01

Detecting the changes is the common issue in many application fields due to the non-stationary distribution of the applicative data, e.g., sensor network signals, web logs and gridrunning logs. Toward Autonomic Grid Computing, adaptively detecting the changes in a grid system can help to alarm the anomalies, clean the noises, and report the new patterns. In this paper, we proposed an approach of self-adaptive change detection based on the Page-Hinkley statistic test. It handles the non-stationary distribution without the assumption of data distribution and the empirical setting of parameters. We validate the approach on the EGEE streaming jobs, and report its better performance on achieving higher accuracy comparing to the other change detection methods. Meanwhile this change detection process could help to discover the device fault which was not claimed in the system logs. © 2010 IEEE.

Plastic flows, typical gel-like spectra, and suitable mechanical properties were obtained from prepared formulations. The retention time was explored in in vivo distribution studies and the effect of the gel containing CsA SLNs on the healing of oral mucosal ulceration was investigated in an animal model. In vivo distribution studies are a very important indicator of the retention time of formulations at the application site.Results: Distribution studies showed that 64.76% ± 8.35% of the formulation coded "F8+SLN" remained on the buccal mucosa 6 hours after application. For the second part of the in vivo experiments, 36 rabbits were separated into three groups: the first group was treated with the gel formulation without the active agent; the second group with the gel formulation containing CsA SLNs; and the third group, used as the control group, received no treatment. Wound healing was established by scoring of the rate of wound healing on Days 3, 6, 9, and 12. Histological observations were made on the same days as the scoring studies. The bioadhesive gel formulation that included CsA SLNs increased the rate of mucosal repair significantly.Conclusion: This study has shown

Falsifying the Sikussak-Oasis Hypothesis for the Tillite Group, East Greenland: Implications for Trezona-like Carbon Isotope Excursions Beneath Neoproterozoic Glacials

Science.gov (United States)

In Neoproterozoic time, East Greenland and East Svalbard (EGES) occupied landward and seaward positions, respectively, on the southern subtropical margin of Laurentia. In both areas, thick clastic-to-carbonate successions are overlain by two discrete glacial and/or periglacial formations, separated by fine basinal clastics. In Svalbard, the younger glacial has a characteristic Marinoan (basal Ediacaran) cap dolostone, but the older glacial is underlain by a 10-permil negative carbon isotope excursion that is indistinguishable from excursions observed exclusively beneath Marinoan glacials in Australia, Namibia and western Laurentia. This led us to propose (Basin Research 16, 297-324, 2004) that the paired glacials in EGES represent the onset and climax of a single, long-lived, Marinoan glaciation. The intervening fine clastics, which contain ikaite pseudomorphs, presumptively accumulated beneath permanent shorefast sea ice (sikussak), analogous to East Greenland fjords during the Younger Dryas and Little Ice Age. In this model, the top of the older glacial signals the start of Snowball Earth. We conducted a preliminary field test of the sikussak hypothesis in Strindberg Land (SL), Andrée Land (AL) and Ella O (EO), East Greenland. We confirmed the correlation of the paired glacials and the Marinoan cap dolostone (missing on EO). In SL, the older glacial (Ulveso Fm) is a thin diamictite overlain by conglomerate lag and a set of megavarves composed of alternating siltstone and ice-rafted debris. In AL and EO, the Ulveso is a sub-glacial diamictite overlain by aeolian and/or marine sandstone. In Bastion Bugt on EO, it is a transgressive shoreface sandstone. This proves that glacial recession occurred under open-water conditions and did not result from permanent sea-ice formation, as stipulated in the sikussak model. There is no evidence that the fine clastic sequence between the glacials formed under an ice cover, or for a single glacial period. This brings us back to

Data Stream Clustering With Affinity Propagation

KAUST Repository

Zhang, Xiangliang

2014-07-09

Data stream clustering provides insights into the underlying patterns of data flows. This paper focuses on selecting the best representatives from clusters of streaming data. There are two main challenges: how to cluster with the best representatives and how to handle the evolving patterns that are important characteristics of streaming data with dynamic distributions. We employ the Affinity Propagation (AP) algorithm presented in 2007 by Frey and Dueck for the first challenge, as it offers good guarantees of clustering optimality for selecting exemplars. The second challenging problem is solved by change detection. The presented StrAP algorithm combines AP with a statistical change point detection test; the clustering model is rebuilt whenever the test detects a change in the underlying data distribution. Besides the validation on two benchmark data sets, the presented algorithm is validated on a real-world application, monitoring the data flow of jobs submitted to the EGEE grid.

The International Telecommunication Union (ITU) Regional Radio Conference (RRC06) established in 2006 a new frequency plan for the introduction of digital broadcasting in European, African, Arab, CIS countries and Iran. The preparation of the plan involved complex calculations under short deadline and required dependable and efficient computing capability. The ITU designed and deployed in-situ a dedicated PC farm, in parallel to the European Organization for Nuclear Research (CERN) which provided and supported a system based on the EGEE Grid. The planning cycle at the RRC06 required a periodic execution in the order of 200,000 short jobs, using several hundreds of CPU hours, in a period of less than 12 hours. The nature of the problem required dynamic workload-balancing and low-latency access to the computing resources. We present the strategy and key technical choices that delivered a reliable service to the RRC06.

This study aims to measure the validity and reliability of Turkish male breast self-examination (MBSE) instrument. The methodological study was performed in 2016 at Ege University, Faculty of Nursing, İzmir, Turkey. The MBSE includes ten steps. For validity studies, face validity, content validity, and construct validity (exploratory factor analysis) were done. For reliability study, Kuder Richardson was calculated. The content validity index was found to be 0.94. Kendall W coefficient was 0.80 (p=0.551). The total variance explained by the two factors was found to be 63.24%. Kuder Richardson 21 was done for reliability study and found to be 0.97 for the instrument. The final instrument included 10 steps and two stages. The Turkish version of MBSE is a valid and reliable instrument for early diagnose. The MBSE can be used in Turkish speaking countries and cultures with two stages and 10 steps.

Reply to Comments on 'Effect of heating rate on kinetic parameters of β-irradiated Li2B4O7:Cu,Ag,P in TSL measurements'

We appreciate the opportunity to respond to comments regarding the paper published by Ege et al (2007 Effect of heating rate on kinetic parameters of β-irradiated Li 2 B 4 O 7 :Cu,Ag,P in TSL measurements Meas. Sci. Technol. 18 889). We would like to thank the authors for taking the time to tell us about their opinion, but unfortunately we do not agree with them completely. In the article presented by Kumar and Chourasiya some comment is advanced to the analysis of the glow curves measured with different heating rates, presented in our recent study. According to our study, the area under the glow curve decreases with increasing heating rate in TL–temperature plots due to the quenching effects. Contrary to this, Kumar and Chourasiya suggest that this decrease is due to the normalization process. Here we hope to clarify any confusion regarding our published study. (reply)

In this paper we describe the use of CREAM and CEMonitor services for job submission and management within the gLite Grid middleware. Both CREAM and CEMonitor address one of the most fundamental operations of a Grid middleware, that is job submission and management. Specifically, CREAM is a job management service used for submitting, managing and monitoring computational jobs. CEMonitor is an event notification framework, which can be coupled with CREAM to provide the users with asynchronous job status change notifications. Both components have been integrated in the gLite Workload Management System by means of ICE (Interface to CREAM Environment). These software components have been released for production in the EGEE Grid infrastructure and, for what concerns the CEMonitor service, also in the OSG Grid. In this paper we report the current status of these services, the achieved results, and the issues that still have to be addressed.

GATE is a software dedicated to Monte Carlo simulations in Single Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET). An important disadvantage of those simulations is the fundamental burden of computation time. This manuscript describes three different techniques in order to improve the efficiency of those simulations. Firstly, the implementation of variance reduction techniques (VRTs), more specifically the incorporation of geometrical importance sampling, is discussed. After this, the newly designed cluster version of the GATE software is described. The experiments have shown that GATE simulations scale very well on a cluster of homogeneous computers. Finally, an elaboration on the deployment of GATE on the Enabling Grids for E-Science in Europe (EGEE) grid will conclude the description of efficiency enhancement efforts. The three aforementioned methods improve the efficiency of GATE to a large extent and make realistic patient-specific overnight Monte Carlo simulations achievable

IGI - the Association for the Italian Grid Infrastructure - has been established as a consortium of 14 different national institutions to provide long term sustainability to the Italian Grid. Its formal predecessor, the Grid.it project, has come to a close in 2006; to extend the benefits of this project, IGI has taken over and acts as the national coordinator for the different sectors of the Italian e-Infrastructure present in EGEE. IGI plans to support activities in a vast range of scientificdisciplines - e.g. Physics, Astrophysics, Biology, Health, Chemistry, Geophysics, Economy, Finance - and any possible extensions to other sectors such as Civil Protection, e-Learning, dissemination in Universities and secondary schools. Among these, the Astrophysics community is active as a user, by porting applications of various kinds, but also as a resource provider in terms of computing power and storage, and as middleware developer.

Microjet sampling in combination with extractive electrospray ionization (EESI) mass spectrometry (MS) was applied to the rapid characterization and classification of extra virgin olive oil (EVOO) without any sample pretreatment. When modifying the composition of the primary ESI spray solvent, mass spectra of an identical EVOO sample showed differences. This demonstrates the capability of this technique to extract molecules with varying polarities, hence generating rich molecular information of the EVOO. Moreover, with the aid of microjet sampling, compounds of different volatilities (e.g.E-2-hexenal, trans-trans-2,4-heptadienal, tyrosol and caffeic acid) could be sampled simultaneously. EVOO data was also compared with that of other edible oils. Principal Component Analysis (PCA) was performed to discriminate EVOO and EVOO adulterated with edible oils. Microjet sampling EESI-MS was found to be a simple, rapid (less than 2 min analysis time per sample) and powerful method to obtain MS fingerprints of EVOO without requiring any complicated sample pretreatment steps.

Shiers, Jamie D

2014-01-01

This chapter focuses on the current and potential use of e-Infrastructures in the domain of eHealth. It starts by identifying a small number of specific Use Cases and then addresses how these can be optimized—or possibly revolutionized—by the use of state-of-the-art distributing computing infrastructures (DCIs). Specific topics that are addressed include “long-term” data preservation (for the duration of a patient’s life as well as (far) beyond for collective-oriented studies), federation of heterogeneous data sources, provision of redundant and highly accessible data storage and federated identity management. The work draws heavily on the author’s experience in distributed computing infrastructures to address the challenges of the Large Hadron Collider at CERN, together with participation in generic e-Infrastructure projects, such as the EGEE project services and EGI. It also benefits from experience in hadron-therapy oriented projects with which CERN has synergies both as an accelerator laborato...

2014-09-01

Full Text Available In this paper, it is aimed at determining the equations and models for estimating the sirospun yarn quality characteristics from the yarn production parameters and cotton fibre properties, which are focused on fibre bundle measurements represented by HVI (high volume instrument. For this purpose, a total of 270 sirospun yarn samples were produced on the same ring spinning machine under the same conditions at Ege University, by using 11 different cotton blends and three different strand spacing settings, in four different yarn counts and in three different twist coefficients. The sirospun yarn and cotton fibre property interactions were investigated by correlation analysis. For the prediction of yarn quality characteristics, multivariate linear regression methods were performed. As a result of the study, equations were generated for the prediction of yarn tenacity, breaking elongation, unevenness and hairiness by using fibre and yarn properties. After the goodness of fit statistics, very large determination coefficients (R2 and adjusted R2 were observed.

GStat 2.0: Grid Information System Status Monitoring

International Nuclear Information System (INIS)

Field, Laurence; Huang, Joanna; Tsai, Min

2010-01-01

Grid Information Systems are mission-critical components in today's production grid infrastructures. They enable users, applications and services to discover which services exist in the infrastructure and further information about the service structure and state. It is therefore important that the information system components themselves are functioning correctly and that the information content is reliable. Grid Status (GStat) is a tool that monitors the structural integrity of the EGEE information system, which is a hierarchical system built out of more than 260 site-level and approximately 70 global aggregation services. It also checks the information content and presents summary and history displays for Grid Operators and System Administrators. A major new version, GStat 2.0, aims to build on the production experience of GStat and provides additional functionality, which enables it to be extended and combined with other tools.

CDF experience with monte carlo production using LCG grid

International Nuclear Information System (INIS)

Griso, S P; Lucchesi, D; Compostella, G; Sfiligoi, I; Cesini, D

2008-01-01

The upgrades of the Tevatron collider and CDF detector have considerably increased the demand on computing resources, in particular for Monte Carlo production. This has forced the collaboration to move beyond the usage of dedicated resources and start exploiting the Grid. The CDF Analysis Farm (CAF) model has been reimplemented into LcgCAF in order to access Grid resources by using the LCG/EGEE middleware. Many sites in Italy and in Europe are accessed through this portal by CDF users mainly to produce Monte Carlo data but also for other analysis jobs. We review here the setup used to submit jobs to Grid sites and retrieve the output, including CDF-specific configuration of some Grid components. We also describe the batch and interactive monitor tools developed to allow users to verify the jobs status during their lifetime in the Grid environment. Finally we analyze the efficiency and typical failure modes of the current Grid infrastructure reporting the performances of different parts of the system used

Distributed Data Management on the Petascale using Heterogeneous Grid Infrastructures with DQ2

CERN Document Server

Branco, M; Salgado, P; Lassnig, M

2008-01-01

We describe Don Quijote 2 (DQ2), a new approach to the management of large scientific datasets by a dedicated middleware. This middleware is designed to handle the data organisation and data movement on the petascale for the High-Energy Physics Experiment ATLAS at CERN. DQ2 is able to maintain a well-defined quality of service in a scalable way, guarantees data consistency for the collaboration and bridges the gap between EGEE, OSG and NorduGrid infrastructures to enable true interoperability. DQ2 is specifically designed to support the access and management of large scientific datasets produced by the ATLAS experiment using heterogeneous Grid infrastructures. The DQ2 middleware manages those datasets with global services, local site services and enduser interfaces. The global services, or central catalogues, are responsible for the mapping of individual files onto DQ2 datasets. The local site services are responsible for tracking files available on-site, managing data movement and guaranteeing consistency of...

Medical Data Manager an Interface between PACS and the gLite Data Management System

CERN Document Server

Montagnat, Johan; Texier, Romain; Nienartowicz, Krzysztof; Baud, Jean-Philippe

2008-01-01

The medical imaging community uses the DICOM image format and protocol to store and exchange data. The Medical Data Manager (MDM) is an interface between DICOM compliant systems such as PACS and the EGEE Data Management System. It opens hospital imaging networks to the world scale Grid while protecting sensitive medical data. It can be accessed transparently from any gLite service. It is an important milestone towards adoption of Grid technologies in the medical imaging community. Hospitals continuously produce tremendous amounts of image data that is managed by local PACS (Picture Archiving and Communication Systems). These systems are often limited to a local network access although the community experiences a growing interest for data sharing and remote processing. Indeed, patient data is often spread out different medical data acquisition centers. Furthermore, researchers in the area often need to analyze large populations whose data can be gathered through federations of PACS. Opening PACS to the outer I...

Security in a Replicated Metadata Catalogue

Koblitz, B

2007-01-01

The gLite-AMGA metadata has been developed by NA4 to provide simple relational metadata access for the EGEE user community. As advanced features, which will be the focus of this presentation, AMGA provides very fine-grained security also in connection with the built-in support for replication and federation of metadata. AMGA is extensively used by the biomedical community to store medical images metadata, digital libraries, in HEP for logging and bookkeeping data and in the climate community. The biomedical community intends to deploy a distributed metadata system for medical images consisting of various sites, which range from hospitals to computing centres. Only safe sharing of the highly sensitive metadata as provided in AMGA makes such a scenario possible. Other scenarios are digital libraries, which federate copyright protected (meta-) data into a common catalogue. The biomedical and digital libraries have been deployed using a centralized structure already for some time. They now intend to decentralize ...

CERN Document Server

Tsaregorodtsev, A

2004-01-01

DIRAC is the LHCb distributed computing grid infrastructure for MC production and analysis. Its architecture is based on a set of distributed collaborating services. The service decomposition broadly follows the ARDA project proposal, allowing for the possibility of interchanging the EGEE/ARDA and DIRAC components in the future. Some components developed outside the DIRAC project are already in use as services, for example the File Catalog developed by the AliEn project. An overview of the DIRAC architecture will be given, in particular the recent developments to support user analysis. The main design choices will be presented. One of the main design goals of DIRAC is the simplicity of installation, configuring and operation of various services. This allows all the DIRAC resources to be easily managed by a single Production Manager. The modular design of the DIRAC components allows its functionality to be easily extended to include new computing and storage elements or to handle new tasks. The DIRAC system al...

2003-03-15

Turkey is abundant in terms of renewable energy resources. Residential and industrial utilization of solar energy started in the 1980s, while the first Build-Operate-Transfer (BOT) windmill park, located at Alacati, Izmir, was commissioned in 1998. Additionally, power generation through solar-wind hybrid systems has recently appeared on the Turkish market. This study investigates the wind and solar thermal power availability in Izmir, located in the western part of Turkey. Simple models were developed to determine wind, solar, and hybrid power resources per unit area. Experimental data, consisting of hourly records over a 5 yr period, 1995-1999, were measured in the Solar/Wind Meteorological Station of the Solar Energy Institute at Ege University. Correlations between solar and wind power data were carried out on an hourly, a daily, and a monthly basis. It can be concluded that possible applications of hybrid systems could be considered for the efficient utilization of these resources. (Author)

Processing moldable tasks on the grid: Late job binding with lightweight user-level overlay

CERN Document Server

Moscicki, J T; Sloot, P M A; Lamanna, M

2011-01-01

Independent observations and everyday user experience indicate that performance and reliability of large grid infrastructures may suffer from large and unpredictable variations. In this paper we study the impact of the job queuing time on processing of moldable tasks which are commonly found in large-scale production grids. We use the mean value and variance of makespan as the quality of service indicators. We develop a general task processing model to provide a quantitative comparison between two models: early and late job binding in a user-level overlay applied to the EGEE Grid infrastructure. We find that the late-binding model effectively defines a transformation of the distribution of makespan according to the Central Limit Theorem. As demonstrated by Monte Carlo simulations using real job traces, this transformation allows to substantially reduce the mean value and variance of makespan. For certain classes of applications task granularity may be adjusted such that a speedup of an order of magnitude or m...

Organising scientific data by dataflow optimisation on the petascale

CERN Document Server

Lassnig, Mario

2008-01-01

Scientific applications on the Grid are in most cases heavily data-dependent. Therefore, improving scheduling decisions based on the co-allocation of data and jobs becomes a primary issue. Hence, it is crucial to analyse the behaviour of existing data management systems in order to provide accurate information for decision-making middlewares in a scalable way. We show current research issues in understanding the behaviour of data management systems on the petascale to improve Grid performance. We analyse the Distributed Data Management system Don Quijote 2 (DQ2) of the High- Energy Physics experiment ATLAS at CERN. ATLAS presents unprecedented data transfer and data storage requirements on the petascale and DQ2 was built to fulfill these requirements. DQ2 is built upon the EGEE infrastructure, while seamlessly enabling interoperability with the American OSG and the Scandinavian NorduGrid infrastructures. Thus it serves as a relevant production-quality system to analyse aspects of dataflow behaviour in the pet...

An ideal teaching program of nuclear chemistry in the undergraduate chemistry curriculum

International Nuclear Information System (INIS)

Uenak, T.

2009-01-01

It is well known that several reports on the common educational problems of nuclear chemistry have been prepared by certain groups of experts from time to time. According to very important statements in these reports, nuclear chemistry and related courses generally do not take sufficient importance in undergraduate chemistry curricula and it was generally proposed that nuclear chemistry and related courses should be introduced into undergraduate chemistry curricula at universities worldwide. Starting from these statements, an ideal program in an undergraduate chemistry curriculum was proposed to be introduced into the undergraduate chemistry program at the Department of Chemistry, Ege University, in Izmir, Turkey during the regular updating of the chemistry curriculum. Thus, it has been believed that this Department of Chemistry has recently gained an ideal teaching program in the field of nuclear chemistry and its applications in scientific, industrial, and medical sectors. In this contribution, the details of this program will be discussed. (author)

Facing Two Rapidly Spreading Internet Worms

CERN Multimedia

IT Department

2009-01-01

The Internet is currently facing a growing number of computer infections due to two rapidly spreading worms. The "Conficker" and "Downadup" worms have infected an estimated 1.1 million PCs in a 24-hour period, bringing the total number of infected computers to 3.5 million [1]. Via a single USB stick, these worms were also responsible for the infection of about 40 laptops at the last EGEE conference in Istanbul. In order to reduce the impact of these worms on CERN Windows computers, the Computer Security Team has suggested several preventive measures described here. Disabling the Windows AutoRun and AutoPlay Features The Computer Security Team and the IT/IS group have decided to disable the "AutoRun" and "AutoPlay" functionality on all centrally-managed Windows computers at CERN. When inserting CDs, DVDs or USB sticks into a PC, "AutoRun" and "AutoPlay" are responsible for automatically playing music or films stored on these media, or ...

2007-04-01

We evaluated the applications and outcomes of substitution urethroplasty, using a variety of techniques, in 65 patients with complex, long-segment urethral strictures. From January 1995 to December 2005, 65 patients with complex urethral strictures >8cm in length underwent substitution urethroplasty. Of the 65 patients, 43 underwent one-stage urethral reconstruction using mucosal grafts (28 colonic mucosal graft, 12 buccal mucosal graft, and 3 bladder mucosal graft), 17 patients underwent one-stage urethroplasty using pedicle flaps, and 5 patients underwent staged Johanson's urethroplasty. The mean follow-up time was 4.8 yr (range; 0.8-10 yr), with an overall success rate of 76.92% (50 of 65 cases). Complications developed in 15 patients (23.08%) and included recurrent stricture in 7 (10.77%), urethrocutaneous fistula in 3 (4.62%), coloabdominal fistula in 1 (1.54%), penile chordee in 2 (3.08%), and urethral pseudodiverticulum in 2 (3.08%). Recurrent strictures and urethral pseudodiverticulum were treated successfully with a subsequent procedure, including repeat urethroplasty in six cases and urethrotomy or dilation in three. Coloabdominal fistula was corrected only by dressing change; five patients await further reconstruction. Penile skin, colonic mucosal, and buccal mucosal grafts are excellent materials for substitution urethroplasty. Colonic mucosal graft urethroplasty is a feasible procedure for complicated urethral strictures involving the entire or multiple portions of the urethra and the technique may also be considered for urethral reconstruction in patients in whom other conventional procedures failed.

2006-01-01

How can one store and analyse the 15 million billion pieces of data that the LHC will produce each year with a computer that isn't the size of a sky-scraper? The IT experts have found the answer: the Grid, which will harness the power of tens of thousands of computers in the world by putting them together on one network and making them work like a single computer achieving a power that has not yet been matched. The Grid, inspired from the Web, already exists - in fact, several of them exist in the field of science. The European EGEE project, led by CERN, contributes not only to the study of particle physics but to medical research as well, notably in the study of malaria and avian flu. The next Discovery Monday invites you to explore this futuristic computing technology. The 'Grid Masters' of CERN have prepared lively animations to help you understand how the Grid works. Children can practice saving the planet on the Grid video game. You will also discover other applications such as UNOSAT, a United Nations...

Distributed Data Analysis in ATLAS

Nilsson, P; The ATLAS collaboration

2012-01-01

Data analysis using grid resources is one of the fundamental challenges to be addressed before the start of LHC data taking. The ATLAS detector will produce petabytes of data per year, and roughly one thousand users will need to run physics analyses on this data. Appropriate user interfaces and helper applications have been made available to ensure that the grid resources can be used without requiring expertise in grid technology. These tools enlarge the number of grid users from a few production administrators to potentially all participating physicists. ATLAS makes use of three grid infrastructures for the distributed analysis: the EGEE sites, the Open Science Grid, and NorduGrid. These grids are managed by the gLite workload management system, the PanDA workload management system, and ARC middleware; many sites can be accessed via both the gLite WMS and PanDA. Users can choose between two front-end tools to access the distributed resources. Ganga is a tool co-developed with LHCb to provide a common interfa...

To investigate whether a virtual reality simulator (LapSim) and traditional box trainer are effective tools for the acquisition of basic laparoscopic skills, and whether the LapSim is superior to the box trainer in surgical education. In a study at Ege University School of Medicine, Izmir, Turkey, between September 2008 and March 2013, 40 first- and second-year residents were randomized to train via the LapSim or box trainer for 4 weeks, and 20 senior residents were allocated to a control group. All 3 groups performed laparoscopic bilateral tubal ligation. Video records of each operation were assessed via the general rating scale of the Objective Structured Assessment of Laparoscopic Salpingectomy and by operation time in seconds. Compared with the control group, the LapSim and box trainer groups performed significantly better in total score (Peducation. Training with a virtual reality simulator or box trainer should be considered before actual laparoscopic procedures are carried out.

Objective was to verify the incidence of cryptosporidiosis among Turkish elementary school students. The study was conducted in the Dept. of Parasitology, Faculty of Medicine, Ege University, Turkey during a 3-month period in 2006. We assessed the fecal samples of 707 children using modified acid-fast and phenol-auramine staining followed by modified Ritchie concentration method. All cryptosporidium species isolates were analysed by nested polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) to differentiate genotypes of the isolates. After the coprological examination, 4 samples were found to be positive for cryptosporidium species oocysts. In the present study, all 4 oocysts were of zoonotic origin and belonged to cryptoporodium parvum genotype 2 indicating that in Turkey the potential sources of human cryptosporidiosis is from animals. The application of genotyping to clinical isolates of cryptosporidium has significantly increased our knowledge and understanding of the distribution and epidemiology of this parasite. The PCR and RFLP techniques represent a more rapid and simple method of genotyping to support epidemiological and clinical investigations than conventional analytical DNA techniques. (author)

When operational, the Large Hadron Collider experiments at CERN will collect tens of petabytes of physics data per year. The worldwide LHC computing grid (WLCG) will distribute this data to over two hundred Tier-1 and Tier-2 computing centres, enabling particle physicists around the globe to access the data for analysis. Although different middleware solutions exist for effective management of storage systems at collaborating institutes, the patterns of access envisaged for Tier-2s fall into two distinct categories. The first involves bulk transfer of data between different Grid storage elements using protocols such as GridFTP. This data movement will principally involve writing ESD and AOD files into Tier-2 storage. Secondly, once datasets are stored at a Tier-2, physics analysis jobs will read the data from the local SE. Such jobs require a POSIX-like interface to the storage so that individual physics events can be extracted. In this paper we consider the performance of POSIX-like access to files held in Disk Pool Manager (DPM) storage elements, a popular lightweight SRM storage manager from EGEE

The Agean is one of the regions in Turkey where thalassemias and abnormal hemoglobins (Hbs) are prevalent. Combined heterozygosity of thalassemia mutations with a variety of structural Hb variants lead to an extremely wide spectrum of clinical and hematological phenotypes which is of importance for prenatal diagnosis. One hundred and seventeen patients and carriers diagnosed by hemoglobin electrophoresis (HPLC), at risk for abnormal hemoglobinopathies were screened for mutational analysis of the beta-globin gene. The full coding the 5' UTR, and the 3' UTR sequences of beta-globin gene (GenBank accession no. U01317) were amplified and sequenced. In this study, a total of 118 (12.24%) structural Hb variant alleles were identified in 1341 mutated beta-chain alleles in Medical Genetics Department of Ege University between January 2006 and November 2013. Here, we report the mutation spectrum of abnormal Hbs associated with the beta-globin gene in Aegean region of Turkey. In the present study, the Hb Hinsdale and Hb Andrew-Minneapolis variants are demonstrated for the first time in the Turkish population.

European projects: a new wave of success

2011-01-01

Since the beginning of this year, no fewer than six new EU projects at CERN have been launched. These are just a third of the projects selected by the European Commission for funding during the course of 2010, bringing in some 23 M€ over a period of two to five years. This makes last year our most successful yet in securing EU support, and places CERN among the top 50 out of more than 10,000 participants in the EU’s seventh Framework Programme.   The success rate of our proposals has been very good ever since the beginning of FP7 in 2007, particularly for projects coordinated by CERN. There has been a clear evolution of CERN’s involvement in EU projects over the last 10 years. In the early days, we tended to target the Marie Curie actions and the e-Infrastructures Programme. The former help us to fulfil our mission to train young people, while the latter supported the development of the European Grid, mainly through the EGEE projects. Later, the Organization became a...

With the evolution of various grid federations, the Condor glide-ins represent a key feature in providing a homogeneous pool of resources using late-binding technology. The CMS collaboration uses the glide-in based Workload Management System, glideinWMS, for production (ProdAgent) and distributed analysis (CRAB) of the data. The Condor glide-in daemons traverse to the worker nodes, submitted via Condor-G. Once activated, they preserve the Master-Worker relationships, with the worker first validating the execution environment on the worker node before pulling the jobs sequentially until the expiry of their lifetimes. The combination of late-binding and validation significantly reduces the overall failure rate visible to CMS physicists. We discuss the extensive use of the glideinWMS since the computing challenge, CCRC-08, in order to prepare for the forthcoming LHC data-taking period. The key features essential to the success of large-scale production and analysis on CMS resources across major grid federations, including EGEE, OSG and NorduGrid are outlined. Use of glide-ins via the CRAB server mechanism and ProdAgent, as well as first hand experience of using the next generation CREAM computing element within the CMS framework is discussed.

The Health-e-Child (HeC) project [1], [2] is an EC Framework Programme 6 Integrated Project that aims to develop a grid-based integrated healthcare platform for paediatrics. Using this platform biomedical informaticians will integrate heterogeneous data and perform epidemiological studies across Europe. The resulting Grid enabled biomedical information platform will be supported by robust search, optimization and matching techniques for information collected in hospitals across Europe. In particular, paediatricians will be provided with decision support, knowledge discovery and disease modelling applications that will access data in hospitals in the UK, Italy and France, integrated via the Grid. For economy of scale, reusability, extensibility, and maintainability, HeC is being developed on top of an EGEE/gLite [3] based infrastructure that provides all the common data and computation management services required by the applications. This paper discusses some of the major challenges in bio-medical data integration and indicates how these will be resolved in the HeC system. HeC is presented as an example of how computer science (and, in particular Grid infrastructures) originating from high energy physics can be adapted for use by biomedical informaticians to deliver tangible real-world benefits

The ETICS system is a distributed software configuration, build and test system designed to fulfil the needs of improving the quality, reliability and interoperability of distributed software in general and grid software in particular. The ETICS project is a consortium of five partners (CERN, INFN, Engineering Ingegneria Informatica, 4D Soft and the University of Wisconsin-Madison). The ETICS service consists of a build and test job execution system based on the Metronome software and an integrated set of web services and software engineering tools to design, maintain and control build and test scenarios. The ETICS system allows taking into account complex dependencies among applications and middleware components and provides a rich environment to perform static and dynamic analysis of the software and execute deployment, system and interoperability tests. This paper gives an overview of the system architecture and functionality set and then describes how the EC-funded EGEE, DILIGENT and OMII-Europe projects are using the software engineering services to build, validate and distribute their software. Finally a number of significant use and test cases will be described to show how ETICS can be used in particular to perform interoperability tests of grid middleware using the grid itself.

Monte Carlo simulations are widely used in emission tomography, for protocol optimization, design of processing or data analysis methods, tomographic reconstruction, or tomograph design optimization. Monte Carlo simulations needing many replicates to obtain good statistical results can be easily executed in parallel using the 'Multiple Replications In Parallel' approach. However, several precautions have to be taken in the generation of the parallel streams of pseudo-random numbers. In this paper, we present the distribution of Monte Carlo simulations performed with the GATE software using local clusters and grid computing. We obtained very convincing results with this large medical application, thanks to the EGEE Grid (Enabling Grid for E-science), achieving in one week computations that could have taken more than 3 years of processing on a single computer. This work has been achieved thanks to a generic object-oriented toolbox called DistMe which we designed to automate this kind of parallelization for Monte Carlo simulations. This toolbox, written in Java is freely available on SourceForge and helped to ensure a rigorous distribution of pseudo-random number streams. It is based on the use of a documented XML format for random numbers generators statuses. (authors)

Full Text Available In this study, a new microcontroller circuit was designed and new computer software was implemented to control power flow currents of renewable energy system, which is established in Solar Energy Institute, Ege University, Bornova, Izmir, Turkey. PIC18F452 microcontroller based electronic circuit was designed to control another electronic circuit that includes power electronic switching components. Readily available standard control circuits are designed for switching single level inverters. In contrary, implemented circuit allows to switch multilevel inverters. In addition, because the efficiency of solar energy panels is considerably low, solar panels should be operated under the maximum power point (MPP. Therefore, MPP algorithm is included in the designed control circuit. Next, the control circuit also includes a serial communication interface based on RS232 standard. Using this interface enables the user to choose all functions available in the control circuit and take status report via computer software. Last, a general purpose command set was designed to establish communication between the computer software and the microcontroller-based control circuit. As a result, it is aimed that this study supply a basis for the researchers who want to develop own control circuits or more visual software.

Analysis gets on the starting Grid

Roger Jones

It is vital for ATLAS to have a functioning distributed analysis system to analyse its data. There are three major Grid deployments in ATLAS (Enabling Grids for E-sciencE, EGEE; the US Open Science Grid, OSG; and the Nordic DataGrid Facility, NGDF), and our data and jobs need to work across all of them, as well as on local machines and batch systems. Users must also be able to locate the data they want and register new small datasets so they can be used later. ATLAS has a suite of products to meet these needs, and a series of Distributed Analysis tutorials are training an increasing number of brave early adopters to use the system. Real users are vital to make sure that the tools are fit for their purpose and to refine our computing model. One such tutorial happened on the 1st and 2nd February at the National eScience Centre in Edinburgh, UK, sponsored by the GridPP Collaboration. The first day introduced an international set of tutees to the basic tools for Grid-based distributed analysis. The architecture...

arcControlTower: the System for Atlas Production and Analysis on ARC

PanDA, the Atlas management and distribution system for production and analysis jobs on EGEE and OSG clusters, is based on pilot jobs to increase the throughput and stability of the job execution on grid. The ARC middleware uses a specific approach which tightly connects the job requirements with cluster capabilities like resource usage, software availability and caching of input files. The pilot concept renders the ARC features useless. The arcControlTower is the job submission system which merges the pilot benefits and ARC advantages. It takes the pilot payload from the panda server and submits the jobs to the Nordugrid ARC clusters as regular jobs, with all the job resources known in advance. All the pilot communication with the PanDA server is done by the arcControlTower, so it plays the role of a pilot factory and the pilot itself. There are several advantages to this approach: no grid middleware is needed on the worker nodes, the fair-share between the production and user jobs is tuned with the arcControlTower load parameters, the jobs can be controlled by ARC client tools. The system could be extended to other submission systems using central distribution.

Grids Today, Clouds on the Horizon

By the time of CCP 2008, the largest scientific machine in the world -– the Large Hadron Collider -– had been cooled down as scheduled to its operational temperature of below 2 degrees Kelvin and injection tests were starting. Collisions of proton beams at 5 + 5 TeV were expected within one to two months of the initial tests, with data taking at design energy (7 + 7 TeV) foreseen for 2009. In order to process the data from this world machine, we have put our "Higgs in one basket" -– that of Grid computing. After many years of preparation, 2008 saw a final "Common Computing Readiness Challenge" (CCRC’08) -– aimed at demonstrating full readiness for 2008 data taking, processing and analysis. By definition, this relied on a world-wide production Grid infrastructure. But change – as always – is on the horizon. The current funding model for Grids – which in Europe has been through 3 generations of EGEE projects, together with related projects in other parts of the world, inc...

Full Text Available To determine the incidence of renal scarring among patients with primary vesicoureteral reflux (VUR and the possible risk factor(s, we studied 90 children (60 girls and 30 boys with VUR followed in the Pediatric Nephrology Unit at the Ege University Hospital from 1998 to 2003. All the patients were assessed for VUR grade by voiding cystoureterography and for presence of renal scarring by (99 m technetium dimercapto-succinic acid scintigraphy. All infants with VUR were given low-dose prophylactic antibiotics and followed-up until resolution of the reflux. Grade of reflux and number of urinary tract infection (UTI episodes (≥3 were found to be statistically significant risk factors for renal scarring (P 0.05. Similarly, there was no statistically significant difference of frequency of renal scarring among the different age groups (P >0.05. We conclude that recurrences of UTI and VUR severity are significant risk factors for renal scarring in children with VUR. Therefore, identification of VUR at an early age may offer the opportunity to prevent episodes of UTI and possible formation of renal scars that may result in end-stage renal failure.

The gLite Workload Management System represents a key entry point to high-end services available on a Grid. Being designed as part of the european Grid within the six years long EU-funded EGEE project, now at its third phase, the WMS is meant to provide reliable and efficient distribution and management of end-user requests. This service basically translates user requirements and preferences into specific operations and decisions - dictated by the general status of all other Grid services - while taking responsibility to bring requests to successful completion. The WMS has become a reference implementation of the 'early binding' approach to meta-scheduling as a neat, Grid-aware solution, able to optimise resource access and to satisfy requests for computation together with data. Several added value features are provided for job submission, different job types are supported from simple batch to a variety of compounds. In this paper we outline what has been achieved to provide adequate workload and management components, suitable to be deployed in a production-quality Grid, while covering the design and development of the gLite WMS and focusing on the most recently achieved results.

Flash flood events of south of France such as the 8th and 9th September 2002 in the Grand Delta territory caused important economic and human damages. Further to this catastrophic hydrological situation, a reform of flood warning services have been initiated (set in 2006). Thus, this political reform has transformed the 52 existing flood warning services (SAC) in 22 flood forecasting services (SPC), in assigning them territories more hydrological consistent and new effective hydrological forecasting mission. Furthermore, national central service (SCHAPI) has been created to ease this transformation and support local services in their new objectives. New functioning requirements have been identified: - SPC and SCHAPI carry the responsibility to clearly disseminate to public organisms, civil protection actors and population, crucial hydrologic information to better anticipate potential dramatic flood event, - a new effective hydrological forecasting mission to these flood forecasting services seems essential particularly for the flash floods phenomenon. Thus, models improvement and optimization was one of the most critical requirements. Initially dedicated to support forecaster in their monitoring mission, thanks to measuring stations and rainfall radar images analysis, hydrological models have to become more efficient in their capacity to anticipate hydrological situation. Understanding natural phenomenon occuring during flash floods mainly leads present hydrological research. Rather than trying to explain such complex processes, the presented research try to manage the well-known need of computational power and data storage capacities of these services. Since few years, Grid technology appears as a technological revolution in high performance computing (HPC) allowing large-scale resource sharing, computational power using and supporting collaboration across networks. Nowadays, EGEE (Enabling Grids for E-science in Europe) project represents the most important

The Spanish Conference on e-Science Grid Computing and the EGEE-EELA Industrial Day (http://webrt.ciemat.es:8000/e-science/index.html) are the first edition of this open forum for the integration of Grid Technologies and its applications in the Spanish community. It has been organised by CIEMAT and CETA-CIEMAT, sponsored by IBM and HP and supported by the European Community through their funded projects EELA, EUChinaGrid and EUMedGrid. To all of them, the conference is very grateful. e-Science is the concept that defines those activities developed by using geographically distributed resources, which scientists (or whoever) can access through the Internet. However, commercial Internet does not fulfil resources such as calculus and massive storage -most frequently in demand in the field of e-Science- since they require high-speed networks devoted to research. These networks, alongside the collaborative work applications developed within them, are creating an ideal scenario for interaction among researchers. Thus, this technology that interconnects a huge variety of computers, information repositories, applications software and scientific tools will change the society in the next few years. The science, industry and services systems will benefit from his immense capacity of computation that will improve the quality of life and the well-being of citizens. The future generation of technologies, which will reach all of these areas in society, such as research, medicine, engineering, economy and entertainment will be based on integrated computers and networks, rendering a very high quality of services and applications through a friendly interface. The conference aims at becoming a liaison framework between Spanish and International developers and users of e-Science applications and at implementing these technologies in Spain. It intends to be a forum where the state of the art of different European projects on e- Science is shown, as well as developments in the research

Chemistry evaluation in French EDF Nuclear Power Plants

Jacquier, Hervé

2014-01-01

The Nuclear Production Division of EDF is comprised of 19 power stations (58 PWR reactors) and 2 national engineering organisations. Nuclear Inspection (IN) is an internal assessment unit of the EDF Nuclear Production Directorate. At the request of the Directorate, it carries out periodic evaluations of all the units of the division. The evaluation of the nuclear sites (EGE: Overall Excellence Assessment) is carried out every 4 years, an intermediate evaluation is also carried out between each EGE. These evaluations are independent of the WANO and IAEA evaluations. Exchanges are carried out between Nuclear Inspection and the other international operators (for example, USA (INPO), England, China...) to share site evaluation methods. These evaluations are carried out by a team of 30 inspectors, reinforced during each evaluation by 10 peers who come from the various French nuclear sites. Nuclear Inspection produces a performance standards document for each FUNCTIONAL AREA, which is based on the requirements of the company. On the whole, 13 areas are evaluated during each inspection, in particular: Management, Operations, Maintenance, Engineering and Chemistry. The area of reactor plant chemistry has been evaluated since 2009. The Chemistry performance standards document is written from the EDF internal requirements and international references. During site evaluations, all the performance standards are assessed for compliance. The Chemistry performance standards document is comprised of 3 topics: Management of plant chemistry, The respect of the chemical and radiochemical specifications, The condition of the laboratories and the sampling lines, measuring equipment, and chemical products. The evaluations carried out make it possible to define strengths and weaknesses which the sites must address. After each evaluation, the assessment is presented to the site management and to the director of EDF Nuclear Production. For 4 years these evaluations have allowed progress to

EXAM-HRA. A comparison between HRA approaches in Nordic countries and in Germany

A joint project called ''EXAM-HRA'' is performed by German, Swedish and Finnish nuclear power plants. The working group presently consists of: - Kent Bladh, RAB. - Anders Karlsson, FKA. - Guenter Becker and Marina Proske, RISA. - Ilkka Maennistoeand Jan-Erik Holmberg, VTT. - Lasse Tunturivuori, TVO. - Christian Bjursten Carlsson and Anders Olsson, Scandpower. - Gunnar Johanson and Lisa Fritzson, ES-konsult. The overall project objective is to provide guidance for a ''state of the art'' human reliability analysis (HRA) for purposes of probabilistic safety assessment (PSA) to ensure that plant specific properties are properly taken into consideration in the analysis /1/. This will also provide means to improve plant features based on HRA and PSA results as well as providing means to improve Nordic and German HRA application for PSA purposes. In previous phase 1, a method of comparing existing HRA analysis has been developed and applied to tasks, which have been modelled for various German and Nordic PSA. In phase 2, three plant visits have been performed in Brunsbuettel (Germany), Forsmark (Sweden), and Olkiluoto (Finland) to compare actions in more detail, and to perform additional analysis using specific variants of HRA methods. Although both German and Nordic partners strongly rely on THERP method, the variants of this HRA method turned out to differ in some aspects. Swedish and Finnish analyses focus on the diagnosis part of the action. They are based on the time correlation of Swain /2/, but they make use of additional performance shaping factors normally not used in Germany. German analyses have a less complex model for diagnosis, but a more thorough investigation of the various action steps, especially considering various types of recovery. This will be demonstrated by an example, which will show the different analyses and their influence on results. (orig.)

Job execution in virtualized runtime environments in grid

Grid systems are used for calculations and data processing in various applied areas such as biomedicine, nanotechnology and materials science, cosmophysics and high energy physics as well as in a number of industrial and commercial areas. Traditional method of execution of jobs in grid is running jobs directly on the cluster nodes. This puts restrictions on the choice of the operational environment to the operating system of the node and also does not allow to enforce resource sharing policies or jobs isolation nor guarantee minimal level of available system resources. We propose a new approach to running jobs on the cluster nodes when each grid job runs in its own virtual environment. This allows to use different operating systems for different jobs on the same nodes in cluster, provides better isolation between running jobs and allows to enforce resource sharing policies. The implementation of the proposed approach was made in the framework of gLite middleware of the EGEE/WLCG project and was successfully tested in SINP MSU. The implementation is transparent for the grid user and allows to submit binaries compiled for various operating systems using exactly the same gLite interface. Virtual machine images with the standard gLite worker node software and sample MS Windows execution environment were created.

In this paper we introduce a new way to deal with Grid portals referring to our implementation. L-GRID is a light portal to access the EGEE/EGI Grid infrastructure via Web, allowing users to submit their jobs from a common Web browser in a few minutes, without any knowledge about the Grid infrastructure. It provides the control over the complete lifecycle of a Grid Job, from its submission and status monitoring, to the output retrieval. The system, implemented as client-server architecture, is based on the Globus Grid middleware. The client side application is based on a java applet; the server relies on a Globus User Interface. There is no need of user registration on the server side, and the user needs only his own X.509 personal certificate. The system is user-friendly, secure (it uses SSL protocol, mechanism for dynamic delegation and identity creation in public key infrastructures), highly customizable, open source, and easy to install. The X.509 personal certificate does not get out from the local machine. It allows to reduce the time spent for the job submission, granting at the same time a higher efficiency and a better security level in proxy delegation and management.

Small computer systems, previously serving primarily for research purposes, have in recent years become indispensable tools for the daily routine examinations in the nuclear medicine departments. The systems of the various manufacturers differ in the number of picture processing functions, and in the algoritms of these. It is a common feature that all nuclear medicine systems strive: a) to contain the processing possibilities (functions) necessary for solution of the tasks arising, b) to ensure the possibility of combining these functions into complex programmes performing complex evaluation procedures, c) to aid the evaluation of the examinations with the application of some ordering principle (the use of differently-coloured press-buttons, predefined macro-instructions, a problem-oriented language, etc...). For optimum utilization of the systems, basic training in computer techniques, a knowledge of the data-processing possibilities in the given system and a appropriate combination of these are indispensable. The evaluating physician in general rarely utilizes the processing possibilities provided by the systems, because of his insufficient knowledge in this respect. In an attempt to overcome the difficulties, the authors, who have been dealing with picture processing problems since 1969, have developed a software system, the SEGAMS (SzEged GAMmacamera Systems), based on principles differing from those used previously

Ganga is a grid job submission and management system widely used in the ATLAS and LHCb experiments and several other communities in the context of the EGEE project. The particle physics communities have entered the LHC operation era which brings new challenges for user data analysis: a strong growth in the number of users and jobs is already noticeable. Current work in the Ganga project is focusing on dealing with these challenges. In recent Ganga releases the support for the pilot job based grid systems Panda and Dirac of the ATLAS and LHCb experiment respectively have been strengthened. A more scalable job repository architecture, which allows efficient storage of many thousands of jobs in XML or several database formats, was recently introduced. A better integration with monitoring systems, including the Dashboard and job execution monitor systems is underway. These will provide comprehensive and easy job monitoring. A simple to use error reporting tool integrated at the Ganga command-line will help to improve user support and debugging user problems. Ganga is a mature, stable and widely-used tool with long-term support from the HEP community. We report on how it is being constantly improved following the user needs for faster and easier distributed data analysis on the grid.

Energy conservation, pollution prevention, resource efficiency, systems integration and life cycle costing are very important terms for sustainable construction. The purpose of this work is to ensure a power supply for the north of the Solar Energy Institute building environment lamps by using wind power to comply with the green building approach. Beside this, the study is to present an energy analysis of the 1.5 kW small wind turbine system (SWTS) with a hub height of 12 m above ground level with a 3 m rotor diameter in Turkey. The SWTS was installed at the Solar Energy Institute of Ege University (latitude 38.24 N, longitude 27.50 E), Izmir, Turkey. NACA 63-622 profile type (National Advisory Committee for Aeronautics) blades of epoxy carbon fiber reinforced plastics were used. The system was commissioned in September 2002, and performance tests have been conducted since then. The performance analysis of the SWTS is quantified and illustrated in the tables, particularly for a reference temperature of 25 deg. C, 30th of October 2003 till 5th of November 2003 for comparison purposes. Test results show that when the average wind speed is 7.5 m/s, 616 W and 76 Hz electricity is produced by the alternator

A gas chromatographic-mass spectrometric (GC-MS) assay method has been developed for simultaneous determination of ethylene glycol monomethyl ether (EGME) and diethylene glycol monomethly ether (DEGME) in spilled aviation fuels. Ethylene glycol monobutyl ether (EGBE) and ethylene glycol monoethyl ether (EGEE) were used as internal standard and surrogate, respectively. Sample preparation consisted of back-extraction with 7 mL dichloromethane after extraction of 50 mL of fuel with 2 mL of water. The extract was concentrated to dryness, dissolved in 100 {mu}L methanol, and analyzed by GC-MS with selected-ion monitoring (SIM). The peaks had good chromatographic properties on a semi-polar column. EGME and DEGME were extracted from fuel with high recovery of 75 and 85%, with small variations, respectively. Method detection limits were 1.3 and 1.0 ng mL{sup -1} for EGME and DEGME, respectively, in spilled fuel. DEGME was detected at concentrations of 22.6 and 19.7 ng mL{sup -1} in two samples from among five free-floating samples collected in a tunnel of a subway station located in the vicinity of an army base in Korea. The method might be useful for differentiation between the fuel-types kerosene and JP-8, which might originate from a storage tank. (orig.)

Grids Today, Clouds on the Horizon

Shiers, J

2008-01-01

By the time of CCP 2008, the world’s largest scientific machine – the Large Hadron Collider – should have been cooled down to its operational temperature of below 20K and injection tests should have started. Collisions of proton beams at 5 + 5 TeV are expected within one to two months of the initial tests, with data taking at design energy (7 + 7 TeV) now foreseen for 2009. In order to process the data from this world machine, we have put our â€ﾜHiggs in one basket” – that of Grid computing. After many years of preparation, 2008 has seen a final â€ﾜCommon Computing Readiness Challenge” (CCRC’08) – aimed at demonstrating full readiness for 2008 data taking, processing and analysis. By definition, this relies on a world‐wide production Grid infrastructure. But change – as always – is on the horizon. The current funding model for Grids – which in Europe has been through 3 generations of EGEE projects, together with related projects in other part...

INTRODUCTION. The relationship between stressful events in the workplace and their effect on health is the subject of numerous studies where the phenomenon of"Mobbing" has become of increasing interest in Social Psychiatry and Occupational Medicine. The aim of this study is to evaluate the relationship between mobbing, occupational stress and personality structure in a group of persons who consulted the "Work Adaptation Disorders Centre" at the Institute of Occupational Medicine between December 2008 and June 2010 for mobbing-related issues. Referring to Leymann Inventory of Psychological Terrorization (LIPT), H. Ege, Occupational Stress Indicator (OSI), Minnesota Multiphasic Personality Inventory 2 (MMPI-2), it has been possible to assess situations of harassment, the sources and the effects of work stress, as well as personality traits in the study group. The results showed that high levels of occupational stress and inadequate coping strategies can lead to depressive, hysterical and paranoid manifestations. Although the relationship between mobbing, occupational stress and personality traits still remains controversial, there is an association between perception of adverse behaviour and mental health, regardless of the subject's ability to cope with stressful life events. The data seem to confirm that the prevention of bullying must be implemented by the work organization and by handling interpersonal conflicts in the work context.

It is well known that in archaeology large use is done of digital technologies and computer applications for data acquisition, storage, analysis and visualization. The approach of modern archaeology to the study of the evolution of ancient human societies is based on the acquisition and analysis of many types of data. The amount of information coming from the archaeology and the other connected sciences and human ties that need to be stored and made available for analysis are increasing at a very large extent. Such data must, however, be analyzed if they are to become valuable information and knowledge. The data analysis use advanced methods developed in mathematics, informatics, physics, geology, biology, ecology, anthropology and in other natural and human sciences. The inevitable result of this is an exponential increase of the amount and complexity of information that must be acquired, transferred, stored, processed and analyzed. From another, side natural disasters, wars and terrorism created enormous damages to the archaeological heritage and in many case destroyed definitively all information about ancient civilizations. It is urgent a long term project for acquiring, storing and preserving at least the archaeological information. The paper presents the EGEE- II ArchaeoGRID project that, using GRID technologies developed at CERN and in other laboratories, is developing a grid able to fit the very challenging requests of contemporary archaeology.

Data location-aware job scheduling in the grid. Application to the GridWay metascheduler

Grid infrastructures constitute nowadays the core of the computing facilities of the biggest LHC experiments. These experiments produce and manage petabytes of data per year and run thousands of computing jobs every day to process that data. It is the duty of metaschedulers to allocate the tasks to the most appropriate resources at the proper time. Our work reviews the policies that have been proposed for the scheduling of grid jobs in the context of very data-intensive applications. We indicate some of the practical problems that such models will face and describe what we consider essential characteristics of an optimum scheduling system: aim to minimise not only job turnaround time but also data replication, flexibility to support different virtual organisation requirements and capability to coordinate the tasks of data placement and job allocation while keeping their execution decoupled. These ideas have guided the development of an enhanced prototype for GridWay, a general purpose metascheduler, part of the Globus Toolkit and member of the EGEE's RESPECT program. Current GridWay's scheduling algorithm is unaware of data location. Our prototype makes it possible for job requests to set data needs not only as absolute requirements but also as functions for resource ranking. As our tests show, this makes it more flexible than currently used resource brokers to implement different data-aware scheduling algorithms.

Full Text Available Objective: To investigate the complications observed in multipl pregnancies which are increasing in day by day. Material and method: We reviewed 173 multiple pregnancies that were followed up in the Department of Obstetric and Gynecology in Ege University during one year period and determined the preterm delivery ratio, discordance between fetuses and investigated the complications which occurred during pregnancy. Results: 148 twin, 24 triplet and 1 quadriplet pregnancies had been followed in a year. While 56 of twin pregnancies and 4 of the triplet pregnancies occurred spontaneously, others conceived with medical treatment or with assisted reproductive technology. Cerclage was performed in 11 pregnancies. Preeclampsia, gestational diabetes mellitus and cholestasis were observed in 12,26 and 8 patients respectively. Twin-to-twin transfusion syndrome was present in 4 patients and one patient had acardiac-acephalic twin pregnancy. Four patients had emergency cesarean section due to ablatio placenta. While 54 patients were hospitalized for one week to twelve weeks because of preterm labour 36 women had preterm premature rupture of the membranes. Only 38 patients had any problem during pregnancy. Discussion: Developments in assisted reproductive technology have been increasing the number of multiple gestations and their complications. The complications due to preterm labor, increased requirement of Neonatal Intensive Care Units and hospital payments are all burden on the families as well as on the social insurance companies.

To evaluate the importance of ultrasonography (US) and magnetic resonance imaging (MRI) in detecting placental adherence defects. Patients diagnozed with total placenta previa (n = 40) in whom hysterectomy was performed due to placental adherence defects (n = 20) or in whom the placenta detached spontaneously after a Cesarean delivery (n = 20) were included into the study between June 2008 and January 2011, at the Department of Obstetrics and Gynecology Ege University (lzmir Turkey). Gray-scale US was used to check for any placental lacunae, sub-placental sonolucent spaces or a placental mass invading the vesicouterine plane and bladder Intra-placental lacunar turbulent blood flow and an increase in vascularization in the vesicouterine plane were evaluated with color Doppler mode. Subsequently all patients had MRI and the results were compared with the histopathologic examinations. The sensitivity of MRI for diagnosis of placental adherence defects before the operation was 95%, with a specificity of 95%. In the presence of at least one diagnostic criterion, the sensitivity and specificity of US were 87.5% and 100% respectively, while the sensitivity of color Doppler US was 62.5% with a specificity of 100%. Currently MRI appears to be the gold standard for the diagnosis of placenta accreta. None of the ultrasonographic criteria is solely sufficient to diagnose placental adherence defects, however they assist in the diagnostic process.

Full Text Available The cyclicality in the development of the Ukrainian economy during the years of its independence under conditions of its political and legal transformations has been studied. On the basis of the analysis of worldwide research the problem of influence of political transformations on the socio-economic development of the state has been identified. There has been developed a methodological approach to studying the evolutionary development of the Ukrainian economy in the context of its European integration, which comprises three main blocks: Block 1 – studying the development of the legal field of Ukraine; Block 2 – studying the policy of development of Ukraine and orientation of its economic system; Block 3 – analyzing the evolutionary development of the Ukrainian economy and determining its cyclical nature. Within the developed approach there were used wavelet models, spectral analysis – Fourier expansion and Johanson test. The paper puts forward three hypotheses: hypothesis 1 – about the existence of short-term 5-year cycles of evolutionary development of the economy; hypothesis 2 – about the existence of a long-term cycle lasing 25 years and conditioned by political and legal processes in the society; hypothesis 3 – about the existence of cointegration relationships between the evolutionary development of the economy of Ukraine and the EU. On the basis of the modern political transformations the phases of development of the Ukrainian legal environment have been defined and comparison of these phases with the specifics of its economic development has been carried out. The analysis of the economic system of Ukraine and its policy made it possible to determine the vector of development of the Ukrainian economy. The approximating (trend and detailing (cyclic components of the economic development of Ukraine were determined with the help of wavelet expansion. Using Fourier analysis for the detailing components allowed to distinguish 5

Akay, Ahmet; Celebi, Gurbuz

2009-01-01

To investigate brain electrical activity accompanying depth perception using random-dot stereograms. Additional experiments were conducted to ascertain the specificity of this potential to depth perception. In the present study, we performed 3 different and independent experiments on 34 subjects to establish the relationship between depth perception and its cortical electrophysiological correlate. Visual evoked potentials in response to visual stimulation by random-dot stereograms were recorded. To achieve this goal, a data acquisition and analysis system, different from common visual evoked potential recording systems, consisting of 2 personal computers, was used. One of the computers was used to generate the visual stimulus patterns and the other to record and digitally average the potentials evoked by the stimuli. This study was carried out at the Department of Biophysics of Ege University Medical School, Izmir, Turkey, from April to December, 2006. A negative potential component, which is thought to arise in association with depth perception, was recorded from the occipital region from 30 of the 34 subjects. Typically, it had a mean latency of 211.46 ms and 6.40 micron V amplitude. The negative potential is related to depth perception, as this component is present in the responses to stimulus, which carries disparity information but is absent when the stimulus is switched to no disparity information. Additional experiments also showed that the specificity of this component to depth perception becomes evident beyond doubt. (author)

The problems in fabrication include the wires being the wrong length, the damage due to the sharp edges, the requried use of temproary protective covers and inadequate training. The problems in the wire harness installation include damge from sharp eges, work on adjacent harnesses, connector damage, and breaking wires. Engineering suggestions from the Apollo-era in reference to the conductors that are reviewed include: the use of plated conductors, and the use of alloys for stronger wiring. In refernce to insulation, the suggestions from Apollo era include the use of polymer tape-wrap wire insulation due to the light weight, however, other types of modern insulation might be more cost-effective. In reference to wire splices and terminal boards the suggestions from the Apollo Era include the use of crimp splices as superior to solder splices, joining multiple wire to a common point using modular plug-ins might be more reliable, but are heavier than crimp splicing. For connectors, the lessons from the Apollo era indicate that a rear environmental seal that does not require additional potting is preferred, and pins should be crimped or welded to the incoming wires and be removable from the rear of the connector.

The aim of this study was to assess the effect of Cognitive Behavioral Therapy (CBT) on sexual functions of women with vaginismus and their husbands, their marital adjustment, and their levels of depression and anxiety symptoms. Twenty-six couples diagnosed as vaginismus according to DSM-IV-TR diagnostic criteria in gynecology outpatient clinics of Izmir Ege Maternity Hospital and Gynecological Diseases Training and Research Hospital were included in the study. The couples were treated with CBT through 50-minute sessions once a week. Pre- and post-treatment, all couples were assessed using a Personal Information Form, Golombok-Rust Inventory of Sexual Satisfaction, Dyadic Adjustment Scale, Beck Depression Inventory, and Beck Anxiety Inventory. There were significant differences in the total and all subscales' scores of sexual functions, significant increase in the marital adjustment, and a significant decrease in anxiety and depression symptom levels after CBT in women who completed the therapy (n = 20). In the husbands, significant recoveries were observed after the therapy in sexual functions total scores and subscales of satisfaction, avoidance, and impotence. However, there was no change in frequency, communication, sensuality, and in the premature ejaculation domains. Also, the marital adjustment scores increased, and significant decreases were observed in depression and anxiety symptom levels. It was observed that CBT is an appropriate therapy approach for vaginismus, and beneficial effects were observed in both women and their husbands in sexual functions, marital adjustment, and levels of depression and anxiety symptoms decreased.

Regarding the complications of peptic ulcer, a perforation remains the most important fatal complication. The aim of our retrospective study was to determine relations between postoperative morbidity and comorbid disease or perioperative risk factors in perforated peptic ulcer. In total, 239 patients who underwent emergency surgery for perforated peptic ulcer in Ege University General Surgery Department, between June 1999 and May 2013 were included in this study. The clinical data concerning the patient characteristics, operative methods, and complications were collected retrospectively. One hundred seventy-five of the 239 patients were male (73.2%) and 64 were female (26.8%). Mean American Society of Anesthesiologists (ASA) score was 1 in the patients without morbidity, but mean ASA score was 3 in the morbidity and mortality groups. Primary suture and omentoplasty was the selected procedure in 228 of the patients. Eleven patients underwent resection. In total, 105 patients (43.9%) had comorbidities. Thirty-seven patients (67.3%) in the morbidity group had comorbid diseases. Thirteen (92.9%) patients in the mortality group had comorbid diseases. Perforation as a complication of peptic ulcer disease still remains among the frequent indications of urgent abdominal surgery. Among the analyzed parameters, age, ASA score, and having comorbid disease were found to have an effect on both mortality and morbidity. The controversial subject in the present study is regarding the duration of symptoms. The duration of symptoms had no effect on mortality nor morbidity in our study.

To assess the complaints of patients who were prescribed antibiotics following orodental problems and the need for antibiotics prescribed for this purpose. Examinations were carried out in the Department of Oral Diagnosis and Radiology, Ege University, Turkey. A total of 203 patients (129 females and 74 males) between 8-70 years of age (mean age 37.7 +/- 13.9). Examination and report. Frequency of unnecessary antibiotic use. Antibiotic therapy was not necessary for 151 (74.4 per cent) cases. Antibiotics were unnecessarily prescribed in 45 cases of acute irreversible pulpitis, 10 chronic apical abscess, 6 acute apical paradontitis, 7 gingivitis, 10 periodontitis, 4 epulis, 2 TMJ (temporomandibular junction) dysfunction, 2 sharp ridge of alveolar bone, 1 burning mouth syndrome and 1 recurrent aphthous stomatitis. In 108 (53.2 per cent) of the cases, the prescribed antibiotics were found to be penicillins, 102 of which were broad-spectrum. It was also determined that only 6 (7.7 per cent) of the 78 cases diagnosed as acute apical abscess were given drainage as local therapy. Principles for treating dental infections suggest that an antibiotic should only be used to supplement and not substitute for conventional surgical methods. Therefore, in cases with acute apical abscess, mechanical treatment (drainage) should be the first step. Inappropriate antibiotic use is quite widespread in dentistry. Dentists should avoid inappropriate use of antibiotics. To prevent inappropriate administration, necessary precautions need to be taken against dispensing antibiotics without prescription.

Targeted therapy against CML commenced with the development of small-molecule tyrosine kinase inhibitors (TKIs exerting their effect against the oncogenic breakpoint cluster region (BCR-ABL fusion protein. Imatinib emerged as the first successful example of a TKI used for the treatment of chronic-phase CML patients and resulted in significant improvements in response rate and overall survival compared with previous treatments. However, a significant portion of patients failed to respond to the therapy and developed resistance against imatinib. Second-generation TKIs nilotinib and dasatinib were to have higher efficiency in clinical trials in imatinib- resistant or intolerant CML patients compared with imatinib. Identification of novel strategies such as dose escalation, drug combination therapy, and use of novel BCR-ABL inhibitors may eventually overcome resistance against BCR-ABL TKIs. This article reviews the history of CML, including the treatment strategies used prediscovery of TKIs and the preclinical and clinical data obtained after the use of imatinib, and the second-generation TKIs developed for the treatment of CML.Keywords: drug resistance, tyrosine kinase inhibitors, chronic myeloid leukemia, imatinib, BCR/ABL

Ethylene glycol ethers (EGEs) are compounds widely used in industry and household products, but their potential, adverse effect on brain is poorly understood, so far. The aim of the present study was to determine whether 4-week administration of 2-buthoxyethanol (BE), 2-phenoxyethanol (PHE), and 2-ethoxyethanol (EE) induces apoptotic process in the rat hippocampus and frontal cortex, and whether their adverse effect on the brain cells can result from disturbances in the glucose metabolism. Experiments were conducted on 40 rats, exposed to BE, PHE, EE, saline or sunflower oil for 4 weeks. Markers of apoptosis and glucose metabolism were determined in frontal cortex and hippocampus by western blot, ELISA, and fluorescent-based assays. BE and PHE, but not EE, increased expression of the active form of caspase-3 in the examined brain regions. BE and PHE increased caspase-9 level in the cortex and PHE also in the hippocampus. BE and PHE increased the level of pro-apoptotic proteins (Bax, Bak) and/or reduced the concentration of anti-apoptotic proteins (Bcl-2, Bcl-xL); whereas, the effect of BE was observed mainly in the cortex and that of PHE in the hippocampus. It has also been found that PHE increased brain glucose level, and both BE and PHE elevated pyruvate and lactate concentration. It can be concluded that chronic treatment with BE and PHE induced mitochondrial pathway of apoptosis, and disturbed glucose metabolism in the rat brain.

Drug-loaded lecithin/chitosan nanoparticles with high entrapment efficiency (86.8%, were successfully prepared by ionic interaction technique. Sustained release of DFV was achieved without any initial burst release. Nanoparticles were also incorporated into chitosan gel at different ratios for preparing a more suitable formulation for topical drug delivery with adequate viscosity. In ex-vivo permeation studies, nanoparticles increased the accumulation of DFV especially in the stratum corneum + epidermis of rat skin without any significant permeation. Retention of DFV from nanoparticle in chitosan gel formulation (0.01% was twofold higher than commercial cream, although it contained ten times less DFV. Nanoparticles in gel formulations produced significantly higher edema inhibition in rats compared with commercial cream in in-vivo studies. Skin blanching assay using a chromameter showed vasoconstriction similar to that of the commercial product. There were no barrier function changes upon application of nanoparticles. In-vitro and in-vivo results demonstrated that lecithin/chitosan nanoparticles in chitosan gel may be a promising carrier for dermal delivery of DFV in various skin disorders.Keywords: skin permeation, anti-inflammatory activity, skin blanching, TEWL

Improving Security in the ATLAS PanDA System

2011-01-01

The security challenges faced by users of the grid are considerably different to those faced in previous environments. The adoption of pilot jobs systems by LHC experiments has mitigated many of the problems associated with the inhomogeneities found on the grid and has greatly improved job reliability; however, pilot jobs systems themselves must then address many security issues, including the execution of multiple users' code under a common 'grid' identity. In this paper we describe the improvements and evolution of the security model in the ATLAS PanDA (Production and Distributed Analysis) system. We describe the security in the PanDA server which is in place to ensure that only authorized members of the VO are allowed to submit work into the system and that jobs are properly audited and monitored. We discuss the security in place between the pilot code itself and the PanDA server, ensuring that only properly authenticated workload is delivered to the pilot for execution. When the code to be executed is from a 'normal' ATLAS user, as opposed to the production system or other privileged actor, then the pilot may use an EGEE developed identity switching tool called gLExec. This changes the grid proxy available to the job and also switches the UNIX user identity to protect the privileges of the pilot code proxy. We describe the problems in using this system and how they are overcome. Finally, we discuss security drills which have been run using PanDA and show how these improved our operational security procedures.

Modern Macintosh computers feature Xgrid, a distributed computing architecture built directly into Apple's OS X operating system. While the approach is radically different from those generally expected by the Unix based Grid infrastructures (Open Science Grid, TeraGrid, EGEE), opportunistic computing on Xgrid is nonetheless a tempting and novel way to assemble a computing cluster with a minimum of additional configuration. In fact, it requires only the default operating system and authentication to a central controller from each node. OS X also implements arbitrarily extensible metadata, allowing an instantly updated file catalog to be stored as part of the filesystem itself. The low barrier to entry allows an Xgrid cluster to grow quickly and organically. This paper and presentation will detail the steps that can be taken to make such a cluster a viable resource for HENP research computing. We will further show how to provide to users a unified job submission framework by integrating Xgrid through the STAR Unified Meta-Scheduler (SUMS), making tasks and jobs submission effortlessly at reach for those users already using the tool for traditional Grid or local cluster job submission. We will discuss additional steps that can be taken to make an Xgrid cluster a full partner in grid computing initiatives, focusing on Open Science Grid integration. MIT's Xgrid system currently supports the work of multiple research groups in the Laboratory for Nuclear Science, and has become an important tool for generating simulations and conducting data analyses at the Massachusetts Institute of Technology

Materials and Methods: The study was carried out in Neurorehabilitation Clinic of Ege University Hospital. Ninety-five subjects (48 women and 47 men aged between 18 and 56 were included in the study. BWT and UEBW were determined non-invasively with a portative ultrasound device; Bladder Scan BVM 6500 (Verathon Inc., WA, USA at a frequency of 3.7 MHz at functional bladder capacity. These values were compared by gender, and their relation was assessed with age, body mass index (BMI and parity. Results: Mean BWT was 2.0 ± 0.4 mm and UEBW was 44.6 ± 8.3 g at a mean volume of 338.0 ± 82.1 ml. Although higher results were obtained in men at higher bladder volumes, the results did not differ significantly by gender. Correlation analyses revealed statistically significant correlation between UEBW and age (r = 0.32. BWT was negatively correlated with volume (r = -0.50 and bladder surface area (r = -0.57. Also, statistically significant correlations were observed between UEBW and volume (r = 0.36, bladder surface area (r = 0.48 and BWT (r = 0.25. Conclusion: Determined values of BWT and UEBW in healthy population are estimated with portative ultrasound devices, which are future promising, for their convenient, easy, non-invasive, time-efficient hand-held use for screening.

Although, patent ductus arteriosus (PDA) is associated with significant morbidity due to hemodynamic instability in preterm infants, the effect of ductus closure on mortality and morbidity is a controversial issue. The aim is to evaluate the efficacy of oral and intravenous (IV) ibuprofen treatment on ductal closure and effects on mortality and bronchoplumonary dysplasia. The medical records of 292 premature infants treated at Ege University Neonatal Intensive Care Unit were retrospectively evaluated. Patients were classified into 3 groups as; No PDA, hemodynamically insignificant PDA (hiPDA) and hemodynamically significant PDA (hsPDA) according to the presence and hemodynamical significance of PDA by echocardiography. hsPDA group was treated with IV or oral ibuprofen. Patent ductus arteriosus was diagnosed by routine echocardiography in 145 patients, of whom 78 (53.7%) had hsPDA. All 65 infants with hiPDA had spontaneous PDA closure. Echocardiographic measurements were similar to those patients treated with oral or IV ibuprofen, as in the response rate to treatment without serious adverse effects. The presence of respiratory distress syndrome, surfactant therapy, late sepsis, bronchopulmonary dysplasia (BPD) and mortality rates were significantly higher in patients with hsPDA. However, with stepwise logistic regression; 5(th) min Apgar score (odds ratio [OR], 1.321, 95% confidence interval [CI], 1.063-1.641, P = 0.012) and gestational age (OR, 1.422, 95% CI, 1.212-1.662, P closure with minimal side effects. HiPDA can close spontaneously; therefore treatment decision should be individualized. However, medical treatment of PDA does not reduce mortality and BPD.

AQUAGRID: The subsurface hydrology Grid service of the Sardinian regional Grid infrastructure

International Nuclear Information System (INIS)

Lecca, G.; Murgia, F.; Maggi, P.; Perias, A.

2007-01-01

AQUAGRID is the subsurface hydrology service of the Sardinian regional Grid infrastructure, designed to deliver complex environmental applications via a user-friendly Web portal. The service is oriented towards the needs of water professionals providing them a flexible and powerful tool to solve water resources management problems and aid decision between different remediation options for contaminated soil and groundwater. In this paper, the AQUAGRID application concept and the enabling technologies are illustrated. The heart of the service is the CODESA-3D hydrogeological model to simulate complex and large groundwater flow and contaminant transport problems. The relevant experience gained from the porting of the CODESA-3D application on the EGEE infrastructure, via the GILDA test bed (https://gilda.ct.infn.it), has contributed to the service prototype. AQUAGRID is built on top of compute-Grid technologies by means of the EnginFrame Grid portal. The portal enables the interaction with the underlying Grid infrastructure and manages the computational requirements of the whole application system. Data management, distribution and visualization mechanisms are based on the tools provided by the DatacroSSing Decision Support System (http://datacrossing.crs4.it).

Cytochrome P450s are associated with the metabolising of a wide range of compounds, including insecticides. CYP353D1v2 has been found to be overexpressed in an imidacloprid-resistant strain of Laodelphax striatellus. Thus, this study was conducted to express CYP353D1v2 in Sf9 cells as a recombinant protein, to assess its ability to metabolise imidacloprid. Western blot and carbon monoxide difference spectrum analysis indicated that the intact CYP353D1v2 protein had been successfully expressed in Sf9 insect cells. Catalytic activity tests with four traditional P450-activity-probing substrates found that the expressed CYP353D1v2 preferentially metabolised p-nitroanisole, ethoxycoumarin and ethoxyresorufin with specific activities of 32.70, 0.317 and 1.22 pmol min -1 pmol -1 protein respectively, but no activity to luciferin-H EGE. The enzyme activity for degrading imidacloprid was tested by measuring substrate depletion and formation of the metabolite. Kinetic parameters for imidacloprid were K m 5.99 ± 0.95 µm and k cat 0.03 ± 0.0004 min -1 . The chromatogram analysis showed clearly the NADPH-dependent depletion of imidacloprid and the formation of an unknown metabolite. The UPLC-MS mass spectrum demonstrated that the metabolite was an oxidative product of imidacloprid, 5-hydroxy-imidacloprid. These results suggest that CYP353D1v2 in L. striatellus is capable of degrading imidacloprid, and that enzyme activity can be evaluated well only by some traditional probing substrates. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

To elucidate the variations of the lateral pharyngeal wall anatomy on physical examination and to assess the clinical importance of the examination of the lateral pharyngeal wall on the presence and severity of obstructive sleep apnoea syndrome. The cross-sectional study was conducted at Ege University Medical School, Izmir, Turkey, between May 2010 and April 2011. The patients were divided into four equal groups: Group 1--snoring without apnoea (age 20-40); Group 2--snoring without apnoea (age 40-60); Group 3--apnoea-hypopnoea index 30/hr. Calibrated oropharynx pictures were taken. Distance between palatoglossal and palatopharyngeal arches, height of palatoglossal and palatopharyngeal arches, uvula width, uvula length and distance between tonsils were measured. SPSS 17 was used for statistical analysis. Of the 80 patients in the study, 44 (55%) were men. Mean distance between palatopharyngeal and palatoglossal arches were 1.55 ± 0.34 cm and 2.70 ± 0.43 cm respectively. Mean height of palatopharyngeal and palatoglossal arches were 0.60 ± 0.21 cm and 1.37 ± 0.36 cm respectively (p > 0.05). Mean uvula width and uvula length were 0.80 ± 0.12cm and 1.25 ± 0.27 cm respectively (p > 0.05). Mean distance between tonsils was 2.24 ± 0.56 cm (p > 0.05). Distance between palatopharyngeal arches was significantly different between groups 3 and 4 (p < 0.05). Palatopharyngeal arch anatomy was found to be significantly associated with obstructive sleep apnoea syndrome severity, especially in patients with normal or small tonsil size. Patients with the palatopharyngeal arches, which narrow the oropharyngeal inlet more than the tonsils, should further be investigated with polysomnography.

This study was undertaken to examine both isolated and concomitant liver injuries to clarify the role of liver trauma on outcome. This retrospective study was a review of all abdominal trauma patients who presented with liver injuries, with or without concomitant injury at Ege University School of Medicine over a 3-year period. Presentation, injury grade, management, and outcomes were analyzed. Patients with isolated hepatic injury (Group A) were compared with patients who had concomitant hepatic injury (liver and spleen/small bowel) (Group B). Significance was set at 95% confidence intervals. Of 368 patients, 80 (21%) presented with liver injury. Of these, the aetiology was as follows: 53 (66.2%) blunt injury, 19 (23%) penetrating injury, and 8 (10%) gun shot trauma. There were 38 patients in Group A and 42 in Group B. Of these 42 patients, 19 were diagnosed with serious types of injury ; eight thoracic, three open long bone fracture, one intra-cardiac, one intracranial. Six additional patients were observed with injuries to large abdominal vessels. Eleven patients (28.9%) with isolated hepatic injury were managed non-operatively. Mortality, intensive care unit and hospital length of stay, and transfusion requirements were significantly higher in Group B. Only the number of transfused blood units and the grade of liver injury were found to be effective on outcome whereas stepwise regression analysis revealed that injury type (penetrating) and blood transfusion were predictive for mortality. This study highlighted that although isolated liver injury results in good outcome with non-operative management, concomitant injuries to the liver lead to a higher failure and mortality rate. However, liver injury itself is rarely responsible for death.

Full Text Available Objectives: To define characteristic fundus autofluorescence (FAF findings in eyes with active polypoidal choroidal vasculopathy (PCV. Materials and Methods: Thirty-five eyes of 29 patients with active PCV who were diagnosed at Ege University Faculty of Medicine, Department of Ophthalmology, Retina Division between January 2012 and November 2014 were included in the study. All the patients underwent a complete ophthalmological examination including fundus photography, spectral-domain optical coherence tomography, fluorescein angiography, FAF photography, and indocyanine green angiography (ICGA. ICGA was used to diagnose active PCV and identify lesion components. FAF findings were described at the retinal site of the corresponding lesions identified and diagnosed using ICGA. Results: The mean age of the 29 study patients (15 men, 14 women was 64.6±7.5 years (range, 54-82 years. ICGA revealed active PCV in 35 eyes, consisting of polypoid lesions in 11 eyes (31.4%, branching vascular networks (BVN in 10 eyes (28.6%, and a combination of polypoid lesions and BVNs in 14 eyes (40%. On FAF images, 4 different patterns were detected at the corresponding retinal sites of 25 polypoid lesions detected by ICGA: confluent hypoautofluorescence with a hyperautofluorescent ring in 18 eyes (72%, hyperautofluorescence with hypoautofluorescent ring in 2 eyes (8%, confluent hypoautofluorescence in 1 eye (4%, and granular hypoautofluorescence in 1 eye (4%. The remaining 3 eyes (12% demonstrated blocked hypoautofluorescence because of the excessive hemorrhaging in the macula. The FAF images showed the granular hypoautofluorescent FAF pattern in all 24 BVNs (100% consistent with the location of the lesions on ICGA. Conclusion: The typical PCV lesions, polypoid lesions and BVNs had characteristic autofluorescent findings on FAF imaging. Non-invasive, quick, and repeatable FAF imaging can be considered a reliable and helpful diagnostic technique for the diagnosis of

Analysis and Modeling of Social In uence in High Performance Computing Workloads

High Performance Computing (HPC) is becoming a common tool in many research areas. Social influence (e.g., project collaboration) among increasing users of HPC systems creates bursty behavior in underlying workloads. This bursty behavior is increasingly common with the advent of grid computing and cloud computing. Mining the user bursty behavior is important for HPC workloads prediction and scheduling, which has direct impact on overall HPC computing performance. A representative work in this area is the Mixed User Group Model (MUGM), which clusters users according to the resource demand features of their submissions, such as duration time and parallelism. However, MUGM has some difficulties when implemented in real-world system. First, representing user behaviors by the features of their resource demand is usually difficult. Second, these features are not always available. Third, measuring the similarities among users is not a well-defined problem. In this work, we propose a Social Influence Model (SIM) to identify, analyze, and quantify the level of social influence across HPC users. The advantage of the SIM model is that it finds HPC communities by analyzing user job submission time, thereby avoiding the difficulties of MUGM. An offline algorithm and a fast-converging, computationally-efficient online learning algorithm for identifying social groups are proposed. Both offline and online algorithms are applied on several HPC and grid workloads, including Grid 5000, EGEE 2005 and 2007, and KAUST Supercomputing Lab (KSL) BGP data. From the experimental results, we show the existence of a social graph, which is characterized by a pattern of dominant users and followers. In order to evaluate the effectiveness of identified user groups, we show the pattern discovered by the offline algorithm follows a power-law distribution, which is consistent with those observed in mainstream social networks. We finally conclude the thesis and discuss future directions of our work.

Although earthquake is not predictable at this moment, with the aid of accurate seismic wave propagation analysis, we could simulate the potential hazards at all distances from possible fault sources by understanding the source rupture process during large earthquakes. With the integration of strong ground-motion sensor network, earthquake data center and seismic wave propagation analysis over gLite e-Science Infrastructure, we could explore much better knowledge on the impact and vulnerability of potential earthquake hazards. On the other hand, this application also demonstrated the e-Science way to investigate unknown earth structure. Regional integration of earthquake sensor networks could aid in fast event reporting and accurate event data collection. Federation of earthquake data center entails consolidation and sharing of seismology and geology knowledge. Capability building of seismic wave propagation analysis implies the predictability of potential hazard impacts. With gLite infrastructure and EUAsiaGrid collaboration framework, earth scientists from Taiwan, Vietnam, Philippine, Thailand are working together to alleviate potential seismic threats by making use of Grid technologies and also to support seismology researches by e-Science. A cross continental e-infrastructure, based on EGEE and EUAsiaGrid, is established for seismic wave forward simulation and risk estimation. Both the computing challenge on seismic wave analysis among 5 European and Asian partners, and the data challenge for data center federation had been exercised and verified. Seismogram-on-Demand service is also developed for the automatic generation of seismogram on any sensor point to a specific epicenter. To ease the access to all the services based on users workflow and retain the maximal flexibility, a Seismology Science Gateway integating data, computation, workflow, services and user communities would be implemented based on typical use cases.

In general, the concept of optimisation in radiation protection and safety appears as cost-minimisation in new procedures, methods in practices, and/or protective actions following unacceptable contamination. In the practical implementation of the concept, the cost of protective actions should be balanced with the benefits of exposure reduction. The monetary value of the averted dose can be assessed by the product of the cost of unit avoided collective dose (alpha-value) and the averted collective dose (ICRP 1991, 1993). According to the ICRP and others, the monetary value of the averted dose - in addition to the avoided health detriment - needs to take into account economical and social circumstances, ethical factors etc. (ICRP 1993, 2000; IBSS 1995; Oughton 2000). Most of the alpha-value assessments have been performed for workers (Hardeman et al. 1998; Lefaure 1998). Due to the different dose limitations and action levels for public exposures the monetary value of the averted dose may vary whether the averted dose refers to workers or to the public. Until now, only a few investigations have been performed to the public exposures. Eeckhoudt et al. (1999) proposed a method based on compensation dependency and on comparisons between the workers and the general public. The present paper includes the results obtained by the WTP method for the public. The questionnaire and analysis were developed by the CEPN (Centre d'Etude sur L'Evaluation de la Protection dans le Domaine Nucleaire, France) for specialists in the nuclear field (Leblanc et al. 1994). In 2000, questionnaire modifications were first introduced to adjust the Hungarian factors (Eged et al. 2001, 2002). The questionnaire was further modified in 2001 to take into account the Hungarian public factors

EXCEM analysis may prove useful to investigators in engineering and other disciplines due to the methodology are being based on the quantities exergy, cost, energy and mass. The main objective of the present study is to investigate between capital costs and thermodynamic losses for devices in solar assisted ground-source heat pump greenhouse heating system (SAGSHPGHS) with a 50 m vertical 32 mm nominal diameter U-bend ground heat exchanger. This system was designed and installed at the Solar Energy Institute, Ege University, Izmir, Turkey. Thermodynamic loss rate-to-capital cost ratios are used to show that, for components and the overall system, a systematic correlation appears to exist between capital cost and exergy loss (total or internal), but not between capital cost and energy loss or external exergy loss. This correlation may imply that devices in successful air conditioning are configured so as to achieve an overall optimal design, by appropriately balancing the thermodynamic (exergy-based) and economic characteristics of the overall system and its devices. The results may, (i) provide useful insights into the relations between thermodynamics and economics, both in general and for SAGSHPGHS (ii) help demonstrate the merits of second-law analysis. It is observed from the results that the maximum exergy destructions in the system particularly occur due to the electrical, mechanical and isentropic efficiencies and emphasize the need for paying close attention to the selection of this type of equipment, since components of inferior performance can considerably reduce the overall performance of the system. In conjunction with this, the total exergy losses values are obtained to be from 0.010 kW to 0.480 kW for the system. As expected, the largest energy and exergy losses occur in the greenhouse and compressor. The ratio of thermodynamic loss rate to capital cost values are obtained for a range from 0.035 to 1.125

The present study highlights the exergetic performance characteristics of an underground air tunnel for greenhouse cooling with a 47 m horizontal, 56 cm nominal diameter U-bend buried galvanized ground heat exchanger. This system was designed and installed in the Solar Energy Institute, Ege University, Izmir, Turkey. Underground air tunnel systems, also known as earth-to-air heat exchangers, are recognized to be outstanding heating, cooling and air heating systems. On the other hand, they have not been used yet in the Turkish market. Greenhouses also have important economical potential in Turkey's agricultural sector. Greenhouses should be cooled during the summer or hot days. In order to establish optimum growth conditions in greenhouses, renewable energy sources should be utilized as much as possible. It is expected that effective use of underground air tunnels with a suitable technology in the modern greenhouses will play a leading role in Turkey in the foreseeable future. The exergy transports between the components and the destructions in each of the components of the system are determined for the average measured parameters obtained from the experimental results. Exergetic efficiencies of the system components are determined in an attempt to assess their individual performances and the potential for improvements is also presented. The daily maximum cooling coefficient of performances (COP) values for the system are also obtained to be 15.8. The total average COP in the experimental period is found to be 10.09. The system COP was calculated based on the amount of cooling produced by the air tunnel and the amount of power required to move the air through the tunnel, while the exergetic efficiency of the air tunnel is found to be in a range among 57.8-63.2%. The overall exergy efficiency value for the system on a product/fuel basis is found to be 60.7%. (author)

The cardiovascular magnetic resonance (CMR) pattern of Churg-Strauss syndrome (CSS) includes myopericarditis, diffuse subendocardial vasculitis or myocardial infarction with or without cardiac symptoms and is usually associated with lack of antineutrophil cytoplasmic antibodies (ANCA). To correlate the CMR pattern with ANCA in CSS, compare it with healthy controls and systemic lupus erythematosus (SLE) patients and re-evaluate 2 yrs after the first CMR. 28 consecutive CSS, aged 42±7 yrs, were referred for CMR and 2 yrs re-evaluation. The CMR included left ventricular ejection fraction (LVEF), T2-weighted (T2-W), early (EGE) and late gadolinium enhanced (LGE) imaging. Their results were compared with 28 systemic lupus erythematosus (SLE) under remission and 28 controls with normal myocardial perfusion, assessed by scintigraphy. CMR revealed acute cardiac lesions in all ANCA (-) CSS with active disease and acute cardiac symptoms and only in one asymptomatic ANCA (+) CSS, with active disease. Diffuse subendocardial fibrosis (DSF) or past myocarditis was identified in both ANCA(+) and ANCA (-) CSS, but with higher incidence and fibrosis amount in ANCA (-) CSS (p<0.05). In comparison to SLE, both ANCA (+) and ANCA (-) CSS had higher incidence of DSF, lower incidence of myocarditis and no evidence of myocardial infarction, due to coronary artery disease (p<0.05). In 2 yrs CMR follow up, 1/3 of CSS with DSF presented LV function deterioration and one died, although immunosuppressive treatment was given early after CSS diagnosis. Cardiac involvement either as DSF or myocarditis, can be detected in both ANCA (+) and ANCA (-) CSS, although more clinically overt in ANCA (-). DSF carries an ominous prognosis for LV function. CMR, due to its capability to detect disease severity, before cardiac dysfunction takes place, is an excellent tool for CSS risk stratification and treatment individualization.

Full Text Available Background: Although, patent ductus arteriosus (PDA is associated with significant morbidity due to hemodynamic instability in preterm infants, the effect of ductus closure on mortality and morbidity is a controversial issue. The aim is to evaluate the efficacy of oral and intravenous (IV ibuprofen treatment on ductal closure and effects on mortality and bronchoplumonary dysplasia. Materials and Methods: The medical records of 292 premature infants treated at Ege University Neonatal Intensive Care Unit were retrospectively evaluated. Patients were classified into 3 groups as; No PDA, hemodynamically insignificant PDA (hiPDA and hemodynamically significant PDA (hsPDA according to the presence and hemodynamical significance of PDA by echocardiography. hsPDA group was treated with IV or oral ibuprofen. Results: Patent ductus arteriosus was diagnosed by routine echocardiography in 145 patients, of whom 78 (53.7% had hsPDA. All 65 infants with hiPDA had spontaneous PDA closure. Echocardiographic measurements were similar to those patients treated with oral or IV ibuprofen, as in the response rate to treatment without serious adverse effects. The presence of respiratory distress syndrome, surfactant therapy, late sepsis, bronchopulmonary dysplasia (BPD and mortality rates were significantly higher in patients with hsPDA. However, with stepwise logistic regression; 5th min Apgar score (odds ratio [OR], 1.321, 95% confidence interval [CI], 1.063-1.641, P = 0.012 and gestational age (OR, 1.422, 95% CI, 1.212-1.662, P < 0.001 were the only significant variables associated with mortality. Gestational age (OR, 0.680, 95% CI, 0.531-0.871, P = 0.002 was the only significant variable associated with BPD shown with logistic regression. Conclusion: Ibuprofen treatment is effective for hsPDA closure with minimal side effects. HiPDA can close spontaneously; therefore treatment decision should be individualized. However, medical treatment of PDA does not reduce

Experience from the 1994 giant Sumatra earthquake, seismic and tsunami hazard have been considered as important issues in the South China Sea and its surrounding region, and attracted many seismologist's interesting. Currently, more than 25 broadband seismic instruments are currently operated by Institute of Earth Sciences, Academia Sinica in northern Vietnam to study the geodynamic evolution of the Red river fracture zone and rearranged to distribute to southern Vietnam recently to study the geodynamic evolution and its deep structures of the South China Sea. Similar stations are planned to deploy in Philippines in near future. In planning, some high quality stations may be as permanent stations and added continuous GPS observations, and instruments to be maintained and operated by several cooperation institutes, for instance, Institute of Geophysics, Vietnamese Acadamy of Sciences and Technology in Vietnam and Philippine Institute of Volcanology and Seismology in Philippines. Finally, those stations will be planed to upgrade as real time transmission stations for earthquake monitoring and tsunami warning. However, high speed data transfer within different agencies is always a critical issue for successful network operation. By taking advantage of both EGEE and EUAsiaGrid e-Infrastructure, Academia Sinica Grid Computing Centre coordinates researchers from various Asian countries to construct a platform to high performance data transfer for huge parallel computation. Efforts from this data service and a newly build earthquake data centre for data management may greatly improve seismic network performance. Implementation of Grid infrastructure and e-science issues in this region may assistant development of earthquake research, monitor and natural hazard reduction. In the near future, we will search for new cooperation continually from the surrounding countries of the South China Sea to install new seismic stations to construct a complete seismic network of the

Grid today, clouds on the horizon

By the time of CCP 2008, the largest scientific machine in the world - the Large Hadron Collider - had been cooled down as scheduled to its operational temperature of below 2 degrees Kelvin and injection tests were starting. Collisions of proton beams at 5+5 TeV were expected within one to two months of the initial tests, with data taking at design energy ( 7+7 TeV) foreseen for 2009. In order to process the data from this world machine, we have put our "Higgs in one basket" - that of Grid computing [The Worldwide LHC Computing Grid (WLCG), in: Proceedings of the Conference on Computational Physics 2006 (CCP 2006), vol. 177, 2007, pp. 219-223]. After many years of preparation, 2008 saw a final "Common Computing Readiness Challenge" (CCRC'08) - aimed at demonstrating full readiness for 2008 data taking, processing and analysis. By definition, this relied on a world-wide production Grid infrastructure. But change - as always - is on the horizon. The current funding model for Grids - which in Europe has been through 3 generations of EGEE projects, together with related projects in other parts of the world, including South America - is evolving towards a long-term, sustainable e-infrastructure, like the European Grid Initiative (EGI) [The European Grid Initiative Design Study, website at http://web.eu-egi.eu/]. At the same time, potentially new paradigms, such as that of "Cloud Computing" are emerging. This paper summarizes the results of CCRC'08 and discusses the potential impact of future Grid funding on both regional and international application communities. It contrasts Grid and Cloud computing models from both technical and sociological points of view. Finally, it discusses the requirements from production application communities, in terms of stability and continuity in the medium to long term.

Horse antithymocyte globulin (h-ATG) (ATGAM(®) ) is the first choice of treatment in very severe patients with aplastic anemia who do not have any HLA matched sibling donor. h-ATG is a heterologous serum that may cause anaphylaxis. Alternative treatment strategies must be planned in case of hypersensitivity. Desensitization must be considered in patients without an alternative treatment of choice. We aimed to present the h-ATG desensitization protocol and consider its effectiveness in patients with aplastic anemia who are hypersensitized with h-ATG and do not have an alternative treatment of choice. Skin prick tests were performed with non-diluted solution in eight very severe patients with aplastic anemia who are followed up in Ege University Children's Hospital. Although skin prick test was found negative in these eight patients, different dilution h-ATG intradermal tests were performed and found positive in all patients. h-ATG desensitization program was started to these hypersensitized patients. Desensitization program was started to six male and two female very severe patients with aplastic anemia whose ages were between seven and 19 yr (median: 12.9 yr). All of the patients completed the desensitization program. While local reaction was seen in two patients, systemic reaction was seen in one patient and late reaction was seen in one patient during and after desensitization program. A successful desensitization program with h-ATG in children with aplastic anemia is presented. Even though there is not an exposure before to such high allergy potential heterologous serum, skin tests should be performed and desensitization must be started to patients who are hypersensitized to h-ATG. As the expected effectiveness of the treatment is so much, the desensitization protocol can be carried out safely and effectively with trained stuff although allergic reactions can be seen. © 2015 John Wiley & Sons A/S.

The advances in science and technology increasingly lead to the appearance of ethical issues and to the complexity of care. Therefore, it is important to define the ethics position of students studying in health departments so that high quality patient care can be achieved. The aim of this study was to examine the ethics position of the students at Shool of Health of an University in western Turkey. The study design was descriptive and cross-sectional. The study population included 540 first, second, third, and fourth year students from the Departments of Nursing, Midwifery, and Rescue and Disaster Management in the 2013-2014 academic year. Data were collected with a Personal Identification Form and The Ethics Position Questionnaire. Obtained data were analyzed with Chi-square test, Confirmatory Factor Analysis, and Nested Analysis of Variance. Ethical considerations: Before conducting the research, approval was obtained from Ege University Clinical Research Ethics Committee in İzmir and written informed consent was taken from all the participants. There was no significant difference in the mean scores for the Ethics Position Questionnaire between the students in terms of years and fields of study. Although the mean scores for the subscale idealism did not differ between fields of study, the mean scores significantly differed between years of study. However, the mean scores for the subscale relativism did not differ in terms of years and fields of study. Whether students are idealistic or relativistic in terms of ethical judgment will be effective in ethical decision-making skills during patient care. Therefore, we need to define the factors that influence students' ethics position in the future. It is suggested that the courses and practices that teach students to be aware of their ethics position to create an ethical outlook can be placed in the curriculum in health schools.

Highlights: • Advanced exergy analysis of a gas engine heat pump drying system for the first time. • Varying exergy efficiency values from 79.71% to 81.66% for the overall drying system. • Obtaining modified exergy efficiencies of 84.50–86.00% for the overall drying system. - Abstract: Some limitations in a conventional exergy analysis may be significantly reduced through an advanced exergy analysis. In this regard, the latter is a very useful tool to assess the real potential for improving a system component by splitting the exergy destruction into unavoidable and avoidable parts. This may provide a realistic measure to deduct the improvement potential for the thermodynamic efficiency of a component. For this purpose, improvement efforts are then made by focusing only on these avoidable parts. In this paper, a gas engine heat pump (GEHP) drying system was analyzed using both conventional and advanced exergy analyses. Three medicinal and aromatic plants (Foeniculum vulgare, Malva sylvestris L. and Thymus vulgaris) were dried in a pilot scale GEHP drier, which was designed, constructed and installed in Ege University, Izmir, Turkey. Drying experiments were performed at an air temperature of 45 °C with an air velocity of 1 m/s. For each system component, avoidable and unavoidable exergy destructions, modified exergy efficiency values and modified exergy destruction ratios were determined. Except for the compressor, the evaporator and the drying cabinet, most of the exergy destructions in the system components were avoidable and these avoidable parts can be reduced by design improvements. For the HP unit and the overall drying system, the values for exergy efficiency were obtained to be in the range of 82.51–85.11% and 79.71–81.66% while those for the modified exergy efficiency were calculated to be in the range of 85.70–89.26% and 84.50–86.00%, respectively

Full Text Available This article considers the opportunities for Russia presented by the launch of China’s Silk Road Economic Belt initiative.This initiative is a comprehensive project for the rapid development of Central Asian countries, and not limited only to transportand logistics to guarantee the supply of Chinese goods to Europe. It is also China’s response to economic and political processes both within the country and in the Asia-Pacific region: the economic slow down and transformation of its social and economic model, diverging income levels, the growing presence of the United States in Asia, and the new divisions of labour within the region. The Silk Road initiative is based on China’s intention to create strong regional value chains, to outsource labour-intensive and environmentally harmful production, to foster the development of north west China including securing political stability in the Xinjiang Uighur Autonomous Region, and to guarantee the use of Chinese construction firms’ capacity. Goods transit is a secondary priority and justified not by commercial benefits from using land routes, but by the need to diversify export risks, arising due to the deteriorating military and political situation in the South China Sea. The 2015 Joint Statement on Cooperation on the Construction of Joint Eurasian Economic Union and the Silk Road Economic Belt projects resolves the issue of all egedly competitive goals of these complementary projects. The Eurasian Economic Union (EEU provides an institutional base for cooperation while the Silk Road initiative provide investments for their development. Russia may benefit from participating in the Silk Road initiative. First, it would help integrate its transportation system into the region’s logistics network and provide additional opportunities for transit and associated logistical services as well as access to growing regional markets. Second, the Silk Road initiative offers opportunities to strengthen

Multidisciplinary approach is a necessity for the appropriate diagnosis and treatment of bone and soft tissue tumors. The Ege University Musculoskeletal Tumor Council offers consultation services to other hospitals in the Aegean region. Since 1988 the Council has met weekly and spent approximately 1,500 hours evaluating almost 6,000 patients with suspected skeletal system tumors. Our objective was to present the data obtained from this patient group. A total of 5,658 patients, suspected to have a musculoskeletal tumor, were evaluated retrospectively. Multiple records of the patients due to multiple attendance to the Council were excluded. The prevalance of the bone and soft tissue tumors in these patients were analysed. Malignant mesenchymal tumors accounted for 39.7% of the total patients, benign tumors for 17%, tumor-like lesions for 17.8% and metastatic carsinomas for 8.6%. Malignant bone tumors were 50.2% and malignant soft tissue tumors were 49.8% of all the sarcomas. Among the malignant bone tumors the most common was osteosarcomas at a rate of 33.6%, followed by Ewing-PNET at 25.5%, chondrosarcomas at 19.4% and haematopoietic tumors at 17.6%. Pleomorphic sarcomas (24.5%), liposarcoma (16.4%), synovial sarcoma (13%) and undifferential sarcomas (8.8%) were the most common types of malignant sof tissue tumors. Benign soft tissue tumors (48%), benign cartilage tumors (28%), giant cell tumor (15%) and osteogenic tumors (9%) were found among the benign tumors. Hemangioma, lipoma, agressive fibromatosis, enchondroma, solitary chondroma and osteoid osteoma were the most common tumors in their groups. Lung (27%), breast (24%), gastrointestinal system (10.5%) and kidney (8.2%) carcinomas were the most common primary sites of the bone metastasis. Turkey still lacks a comprehensive series indicating the incidence and diagnostic distribution of bone and soft tissue tumors. The presented data would add to our knowledge on the specific rates of the bone and soft tissue

THE SPACE IN KOLO GORAH (1851 BY OTO ŠIJAKOVIĆ

Full Text Available Our interpretation of Kolo gorah iliti pozdrav veseli prastaromu i veleslavnomu od Požege gradu i velenarodnim njegovim vilam, a composition in verse by Oto Šijaković (Ilok, 1823 – Bač, 1878, a Franciscan priest and poet, written and performed in 1851 in Požega and published in Zagreb in 1862, focuses on the space in which the action takes place. As pozdrav, a greeting, is part of social behavior, Kolo gorah is first analyzed as a speech act according to John Austin’s speech act theory. The analysis of the ideologemic aspect, with reference to Russian semiotic theorists, namely Lotman and Toporov, confirms that the landscape can be turned into a symbol and, as a literary space, it can express non-spatial relations and form social, political and ideological aspects of one’s worldview. Since the landscape in Kolo gorah is formed as an idealized and national space, the analysis is focused on the way this work fits into the literature of Croatian Romanticism and its role in national integration processes which took place in the 19th century. Being based on theories of nations and nationalism by Benedict Anderson, Eric Hobsbawm and Anthony D. Smith, the role of this work in the shaping of the national identity has been analyzed from the following thematic aspects: collective past, present and future, mutual space, mutual culture and national man. Although referring to concrete geographical locations and hills surrounding Požega, the literary space in Kolo gorah is idyllic and in it Oto Šijaković incorporates a historical and cultural dimension, political ideas and worldviews, and then spiritualizes it by introducing mythical creatures and perceiving it as part of God's announcement. In the shaping of the literary space, the author uses idealizations in the form of a glorious past, beautiful present and joyful future on the time axis, and in the form of positive people living in an ideal state and church community on the social axis.

Distributed data analysis using Grid resources is one of the fundamental applications in high energy physics to be addressed and realized before the start of LHC data taking. The needs to manage the resources are very high. In every experiment up to a thousand physicists will be submitting analysis jobs to the Grid. Appropriate user interfaces and helper applications have to be made available to assure that all users can use the Grid without expertise in Grid technology. These tools enlarge the number of Grid users from a few production administrators to potentially all participating physicists. The GANGA job management system (http://cern.ch/ganga), developed as a common project between the ATLAS and LHCb experiments, provides and integrates these kind of tools. GANGA provides a simple and consistent way of preparing, organizing and executing analysis tasks within the experiment analysis framework, implemented through a plug-in system. It allows trivial switching between running test jobs on a local batch system and running large-scale analyzes on the Grid, hiding Grid technicalities. We will be reporting on the plug-ins and our experiences of distributed data analysis using GANGA within the ATLAS experiment. Support for all Grids presently used by ATLAS, namely the LCG/EGEE, NDGF/NorduGrid, and OSG/PanDA is provided. The integration and interaction with the ATLAS data management system DQ2 into GANGA is a key functionality. An intelligent job brokering is set up by using the job splitting mechanism together with data-set and file location knowledge. The brokering is aided by an automated system that regularly processes test analysis jobs at all ATLAS DQ2 supported sites. Large numbers of analysis jobs can be sent to the locations of data following the ATLAS computing model. GANGA supports amongst other things tasks of user analysis with reconstructed data and small scale production of Monte Carlo data.

In this work, novel FEX loaded water in oil microemulsion (w/o was designed to improve bioavailability and compared with Fexofen® syrup in in vitro and in vivo studies. In addition, pharmacokinetic parameters in permeability studies were estimated by using WinNonLin software program. w/o microemulsion system was optimized using a pseudoternary phase diagram, composed of span 80/lutrol F 68 (9.5:0.5 w/w, oleic acide, isopropyl alcohol and water as surfactant mixture; oil and cosurfactant was developed for oral drug delivery. w/o microemulsion systems were characterized by phase behavior, particle size, viscosity and solubilization capacity. In vitro studies were studied using Caco-2 cell monolayer. Pharmacokinetic parameters of w/o microemulsion were investigated in rabbits and compared to Fexofen® syrup. Fexofen® syrup and microemulsion were administered by oral gavage at 6 mg/kg of the same concentration. The experimental results indicated that microemulsion (HLB = 5.53 formed nanometer sized droplets (33.29 ± 1.76 and had good physical stability. This microemulsion increased the oral bioavailability of FEX which was highly water-soluble but fairly impermeable. The relative bioavailability of FEX microemulsion was about 376.76% compared with commercial syrup in rabbits. In vitro experiments were further employed for the enhanced effect of the microemulsion for FEX. These results suggest that novel w/o microemulsion plays an important role in enhancing oral

The comet assay is a widely used biomonitoring tool for DNA damage. The most commonly used cells in human studies are lymphocytes. There is an urgent need to find an alternative target human cell that can be collected from normal subjects with minimal invasion. There are some reports of buccal cells, collected easily from the inside of the mouth, being used in studies of DNA damage and repair, and these were of interest. However, our preliminary studies following the published protocol showed that buccal cells sustained massive damage and disintegrated at the high pH [O. Ostling, K.J. Johanson.

Therefore, the aims of this study were to develop a protocol than enabled buccal cell lysis and DNA damage testing in the comet assay, and to use the model to evaluate the potential use of the buccal cell model in human biomonitoring and nutritional study. Specifically, we aimed to investigate intra- and inter-individual differences in buccal cell DNA damage (as strand breaks), the effect of in vitro exposure to both a standard oxidant challenge and antioxidant treatment, as well as in situ exposure to an antioxidant-rich beverage and supplementation-related effects using a carotenoid-rich food. Successful lysis was achieved using 0.25% trypsin for 30 min followed by proteinase K (1 mg/ml) treatment for 60 min. When this procedure was performed on cells pre-embedded in agarose on a microscope slide, followed by electrophoresis (in 0.01 M NaOH, 1 mM EDTA, pH 9.1, 18 min at 12 V), a satisfactory comet image was obtained, though inter-individual variation was quite wide. Pre-lysis exposure of cells to a standard oxidant challenge (induced by H 2 O 2 ) increased DNA strand breaks in a dose related manner, and incubation of cells in Trolox

Hydrometeorological science has made strong progress over the last decade at the European and worldwide level: new modeling tools, post processing methodologies and observational data and corresponding ICT (Information and Communication Technology) technologies are available. Recent European efforts in developing a platform for e-Science, such as EGEE (Enabling Grids for E-sciencE), SEEGRID-SCI (South East Europe GRID e-Infrastructure for regional e-Science), and the German C3-Grid, have demonstrated their abilities to provide an ideal basis for the sharing of complex hydrometeorological data sets and tools. Despite these early initiatives, however, the awareness of the potential of the Grid technology as a catalyst for future hydrometeorological research is still low and both the adoption and the exploitation have astonishingly been slow, not only within individual EC member states, but also on a European scale. With this background in mind and the fact that European ICT-infrastructures are in the progress of transferring to a sustainable and permanent service utility as underlined by the European Grid Initiative (EGI) and the Partnership for Advanced Computing in Europe (PRACE), the Distributed Research Infrastructure for Hydro-Meteorology Study (DRIHMS, co-Founded by the EC under the 7th Framework Programme) project has been initiated. The goal of DRIHMS is the promotion of the Grids in particular and e-Infrastructures in general within the European hydrometeorological research (HMR) community through the diffusion of a Grid platform for e-collaboration in this earth science sector: the idea is to further boost European research excellence and competitiveness in the fields of hydrometeorological research and Grid research by bridging the gaps between these two scientific communities. Furthermore the project is intended to transfer the results to areas beyond the strict hydrometeorology science as a support for the assessment of the effects of extreme

In the Lisbon strategy, the 2005 European Council identified knowledge and innovation as the engines of sustainable growth and stated that it is essential to build a fully inclusive information society. In parallel, the World Conference on Disaster Reduction (Hyogo, 2005), defined among its thematic priorities the improvement of international cooperation in hydrometeorology research activities. This was recently confirmed at the joint press conference of the Center for Research on Epidemiology of Disasters (CRED) with the United Nations International Strategy for Disaster Reduction (UNISDR) Secretariat, held on January 2009, where it was noted that flood and storm events are among the natural disasters that most impact human life.

Vibroacoustics of the piano soundboard: Reduced models, mobility synthesis, and acoustical radiation regime

Boutillon, Xavier; Ege, Kerem

2013-09-01

In string musical instruments, the sound is radiated by the soundboard, subject to the strings excitation. This vibration of this rather complex structure is described here with models which need only a small number of parameters. Predictions of the models are compared with the results of experiments that have been presented in Ege et al. [Vibroacoustics of the piano soundboard: (non)linearity and modal properties in the low- and mid-frequency ranges, Journal of Sound and Vibration 332 (5) (2013) 1288-1305]. The apparent modal density of the soundboard of an upright piano in playing condition, as seen from various points of the structure, exhibits two well-separated regimes, below and above a frequency flim that is determined by the wood characteristics and by the distance between ribs. Above flim, most modes appear to be localised, presumably due to the irregularity of the spacing and height of the ribs. The low-frequency regime is predicted by a model which consists of coupled sub-structures: the two ribbed areas split by the main bridge and, in most cases, one or two so-called cut-off corners. In order to assess the dynamical properties of each of the subplates (considered here as homogeneous plates), we propose a derivation of the (low-frequency) modal density of an orthotropic homogeneous plate which accounts for the boundary conditions on an arbitrary geometry. Above flim, the soundboard, as seen from a given excitation point, is modelled as a set of three structural wave-guides, namely the three inter-rib spacings surrounding the excitation point. Based on these low- and high-frequency models, computations of the point-mobility and of the apparent modal densities seen at several excitation points match published measurements. The dispersion curve of the wave-guide model displays an acoustical radiation scheme which differs significantly from that of a thin homogeneous plate. It appears that piano dimensioning is such that the subsonic regime of acoustical

Full Text Available The use of organic wastes in agriculture, forestry and land reclamation has been increasingly identified as an important issue for soil fertility, soil conservation and residue disposal. Using organic wastes in agriculture helps not only to dispose these materials economi¬cally, but also reduces negative effects on the envi¬ronment. In the present study, composted tobacco waste (CTW combined with farmyard manure (FM at different ratios was applied to Typic Xerofluvent soil, and the influence of these amendments on the yield and nutrient composition of butter head letttuce (Lactuca sativa L. var. capitata were investigated. The experiment was conducted in 18 parcels in a randomized-block design with three replications at the Agriculture Faculty’s Research Farm of Ege University in Menemen plain, in the Western Anatolia Region of Turkey (38°58′35.51″-38°58′36.03″N; 27°03′84.56″-27°03′89.81″E. Organic materials were applied to the soil after composting. The treatments were (1 control, (2 12.5 t ha-1 FM + 37.5 t ha-1 CTW, (3 25 t ha-1 FM + 25 t ha-1 CTW, (4 50 t ha-1 FM, (5 50 t ha-1 CTW, and (6 37.5 t ha-1 FM + 12.5 t ha-1 CTW. The maximum yield was obtained during the 1st vegetation period (62,7 t ha-1 in the 100 % CTW application. On account of the 2nd vegetation period’s coinciding with winter and the coldness of the months December, January and February, there happened a slowdown in the lettuce yield. The highest total yield of lettuce in both vegetation periods (102.7 t ha-1 was determined in 100% CTW application parcels. The lower lettuce yields were determined in the control parcels. CTW and FM applications raised N, P, K Ca, Mg, Na, Fe, Zn and Mn contents of the lettuce. According to the results obtained, it can be said that CTW can be used in agricultural fields just like FM.

The Strain Energy, Seismic Moment and Magnitudes of Large Earthquakes

Science.gov (United States)

Purcaru, G.

2004-12-01

The strain energy Est, as potential energy, released by an earthquake and the seismic moment Mo are two fundamental physical earthquake parameters. The earthquake rupture process ``represents'' the release of the accumulated Est. The moment Mo, first obtained in 1966 by Aki, revolutioned the quantification of earthquake size and led to the elimination of the limitations of the conventional magnitudes (originally ML, Richter, 1930) mb, Ms, m, MGR. Both Mo and Est, not in a 1-to-1 correspondence, are uniform measures of the size, although Est is presently less accurate than Mo. Est is partitioned in seismic- (Es), fracture- (Eg) and frictional-energy Ef, and Ef is lost as frictional heat energy. The available Est = Es + Eg (Aki and Richards (1980), Kostrov and Das, (1988) for fundamentals on Mo and Est). Related to Mo, Est and Es, several modern magnitudes were defined under various assumptions: the moment magnitude Mw (Kanamori, 1977), strain energy magnitude ME (Purcaru and Berckhemer, 1978), tsunami magnitude Mt (Abe, 1979), mantle magnitude Mm (Okal and Talandier, 1987), seismic energy magnitude Me (Choy and Boatright, 1995, Yanovskaya et al, 1996), body-wave magnitude Mpw (Tsuboi et al, 1998). The available Est = (1/2μ )Δ σ Mo, Δ σ ~=~average stress drop, and ME is % \\[M_E = 2/3(\\log M_o + \\log(\\Delta\\sigma/\\mu)-12.1) ,\\] % and log Est = 11.8 + 1.5 ME. The estimation of Est was modified to include Mo, Δ and μ of predominant high slip zones (asperities) to account for multiple events (Purcaru, 1997): % \\[E_{st} = \\frac{1}{2} \\sum_i {\\frac{1}{\\mu_i} M_{o,i} \\Delta\\sigma_i} , \\sum_i M_{o,i} = M_o \\] % We derived the energy balance of Est, Es and Eg as: % \\[ E_{st}/M_o = (1+e(g,s)) E_s/M_o , e(g,s) = E_g/E_s \\] % We analyzed a set of about 90 large earthquakes and found that, depending on the goal these magnitudes quantify differently the rupture process, thus providing complementary means of earthquake characterization.

The concept of "work" and the social interactions in the workplace contribute to develop the working satisfaction and the social and personal identity of the adult. The aim of the survey is that of checking up on the presence of a statistically significant relation between The Depression Syndrome and The Mobbing Phenomenon. It is necessary to understand and value if and how some of the employer's behaviours could have a heavy influence on the worker's psychophysical condition, up to causing a state of anxiety and depression. It has been used the now famous "LIPT" (Leymann Inventory of Psychological Terror), elaborated by Leymann at the beginning of the 90's. It is a short anonymous questionnaire recognized all over Europe as a standard to confirm the Mobbing existence in organizational contexts. The current version of the questionnaire is called "LIPT EGE", a more suitable tool to check the seven parameters of the Mobbing determination, as well as the quantification of the consequent harm. Some scales for depressive symptoms evaluation have been added to the Mobbing questionnaire: The Self Rating Depression Scale (SDS) and The Depression Status Inventory (DSI) of Zung. The questionnaires are administered to 500 workers women in public and private corporation in Sicily, exactly in Siracusa and Catania provinces. 206 women aged 34-50 have answered the questionnaires. In addition to the age and the sex, the distinction variables of the examined people are the position in the firm, nationality, vocational qualification, and the yearly gross income. The research has begun in july and has continued on august 2006. Attention has been focused only on the administrative sectors. Through the chi2 test and the exact Fisher test, the dependence between the changeable presence of depression in the two questionnaires (Zung 1 and Zung 2) and every single variable of the questionnaire on the Mobbing has been pointed out. In particular, the results establish a connection between

Accurate radiotherapy treatment requires the delivery of a precise dose to the tumour volume and a good knowledge of the dose deposit to the neighbouring zones. Computation of the treatments is usually carried out by a Treatment Planning System (T.P.S.) which needs to be precise and fast. The G.A.T.E. platform for Monte-Carlo simulation based on G.E.A.N.T.4 is an emerging tool for nuclear medicine application that provides functionalities for fast and reliable dosimetric calculations. In this thesis, we studied in parallel a validation of the G.A.T.E. platform for the modelling of electrons and photons low energy sources and the optimized use of grid infrastructures to reduce simulations computing time. G.A.T.E. was validated for the dose calculation of point kernels for mono-energetic electrons and compared with the results of other Monte-Carlo studies. A detailed study was made on the energy deposit during electrons transport in G.E.A.N.T.4. In order to validate G.A.T.E. for very low energy photons (<35 keV), three models of radioactive sources used in brachytherapy and containing iodine 125 (2301 of Best Medical International; Symmetra of Uro- Med/Bebig and 6711 of Amersham) were simulated. Our results were analyzed according to the recommendations of task group No43 of American Association of Physicists in Medicine (A.A.P.M.). They show a good agreement between G.A.T.E., the reference studies and A.A.P.M. recommended values. The use of Monte-Carlo simulations for a better definition of the dose deposited in the tumour volumes requires long computing time. In order to reduce it, we exploited E.G.E.E. grid infrastructure where simulations are distributed using innovative technologies taking into account the grid status. Time necessary for the computing of a radiotherapy planning simulation using electrons was reduced by a factor 30.

The Environment oriented Satellite Data Processing Platform (ESIP) is developed through the SEE-GRID-SCI (SEE-GRID eInfrastructure for regional eScience) co-funded by the European Commission through FP7 [1]. The gProcess Platform [2] is a set of tools and services supporting the development and the execution over the Grid of the workflow based processing, and particularly the satelite imagery processing. The ESIP [3], [4] is build on top of the gProcess platform by adding a set of satellite image processing software modules and meteorological algorithms. The satellite images can reveal and supply important information on earth surface parameters, climate data, pollution level, weather conditions that can be used in different research areas. Generally, the processing algorithms of the satellite images can be decomposed in a set of modules that forms a graph representation of the processing workflow. Two types of workflows can be defined in the gProcess platform: abstract workflow (PDG - Process Description Graph), in which the user defines conceptually the algorithm, and instantiated workflow (iPDG - instantiated PDG), which is the mapping of the PDG pattern on particular satellite image and meteorological data [5]. The gProcess platform allows the definition of complex workflows by combining data resources, operators, services and sub-graphs. The gProcess platform is developed for the gLite middleware that is available in EGEE and SEE-GRID infrastructures [6]. gProcess exposes the specific functionality through web services [7]. The Editor Web Service retrieves information on available resources that are used to develop complex workflows (available operators, sub-graphs, services, supported resources, etc.). The Manager Web Service deals with resources management (uploading new resources such as workflows, operators, services, data, etc.) and in addition retrieves information on workflows. The Executor Web Service manages the execution of the instantiated workflows

As director of the American Association of Variable Star Observers for thirty years, Janet Mattei led the organization through a series of major improvements and in the process, helped and influenced amateur and professional astronomers around the world. Having successfully tackled many challenges, however, Janet lost her battle with acute myelogenous leukemia on 22 March 2004. One of five children of Bella and Baruk Akyüz, Janet was born on 2 January 1943 in Bodrum, Turkey and received her pre-collegiate education there. She attended Brandeis University from 1962 until 1965 on a full Wein Scholarship, earning a BA in General Science. After eighteen months of supervising a cardiopulmonary laboratory, in 1967 she returned to Turkey to teach physics and mathematics in a high school, and then entered graduate school at Turkey's Ege University. Janet learned of the summer scholarships available at the Maria Mitchell Observatory on Nantucket, and applied to observatory director Dorrit Hoffleit for the opportunity to come back to the United States and learn about variable stars. That summer (1969) she learned to love variable stars, became acquainted with the AAVSO, and met her future husband, Michael Mattei. In 1970, after she earned her master's degree in astronomy at Ege University, Janet entered the University of Virginia where she earned a second master's degree in 1972 with a thesis on T Tauri stars. After receiving her degree in Virginia, Janet married Mike Mattei and became an assistant to Margaret Mayall at AAVSO headquarters. When Mayall decided to retire in 1973, the AAVSO Council asked Janet to assume the helm as director of the association. With such a sudden advance in her responsibilities, Janet had to rapidly learn the management side of running the organization as well as keep up with the day-to-day scientific activities - responding to requests for data, recording observations as pencil-points on paper charts, and predicting future maxima of long

Preliminary results show significant differences in diversity for many species between contaminated and reference sites. However, more research is needed to draw conclusions about the cause of such observations. Nevertheless, by combining a through site characterisation and exposure assessment with a variety of ecologically relevant biomarker and endpoint measurements, the data produced should be a valuable contribution to international activities looking at the impacts of chronic exposure of ionising radiation on non-human species.

Such treatment options are targeted therapies of the vascular endothelial growth factor (VEGF pathway and the mammalian target of the rapamycin pathway. With the use of tyrosine kinase inhibitors (TKIs and mammalian target of the rapamycin inhibitors, overall survival has increased up to 2 years. In Turkey, due to applicable reimbursement conditions for patients with metastatic renal cell carcinoma (mRCC, interferon use is mandated as a first-line treatment, thus providing information on the use of everolimus only after initial interferon and second-line VEGF-targeted treatments such as VEGF-TKI. Patients and methods: To provide a first real-life data set in Turkey, we conducted a prospective, non-interventional, observational study and assessed the efficacy and safety of everolimus after two lines of treatment including interferon.

restricted volume in the multi-dimensional parameter space. In order to constrain concentration of minerals we used equilibrium of mineral associations for selected P-T condition obtained by free Gibbs energy minimization (c.f. Stixrude & Lithgow-Bertelloni, 2005). We also considered the mineralogical composition of upper mantle xenoliths, although the representativeness of xenoliths in Precambrian rocks could be treated with care, if one tries to describe the modern mantle. As a first step, we estimated 1D model of mineralogical composition in the depth range of 35-350 km using the IASP91 reference model (Kennett & Engdahl, 1991). Both the P- and S- wave velocities were used for inversion, in order to improve the reliability of the model. More comprehensive result could be obtained if density distribution is involved. In our study we used the 1D PEMC density model (Dziewonski, Hales & Lapwood, 1975) as it is the most adequate for the continental lithosphere. The 1D modeling showed that the garnet lherzolite model (forsterite, fayalite, enstatite, ferrosilite, diopside, jadeite, pyrope) can be considered as a basic one. The end-members of olivine and orthopyroxene solutions were included with the aim of Fe/Mg ratio estimation. Testing with modified models including hedenbergite, harzburgite spinel, etc. showed that these minerals have no significant influence on bulk elastic properties. Selected set of minerals allows modelling the most species of peridote-pyroxenite associations known from xenoliths investigations (Kukkonen, Kuusisto, Lehtonen, & Peltonen, 2008; Lehtonen, O'Brien, Peltonen, Johanson, & Pakkanen, 2004). However, there exist also a number of evidences for mantle eclogite xenoliths from the region under study and its surrounding (Lehtonen et al., 2004; Peltonen, Kinnunen, & Huhma, 2002). That is why we also made modelling for garnet-clinopyroxene model of eclogite. The volumetric mineral compositions obtained were transformed into weight concentration of rock

The Sultan (Mesir Mosque, which is one of the monumental works, has a privileged position due to being a rare monumental structure that reflects the Ottoman classical period architecture features. The mosque is used for worship and seen as a focus of interest due to being a mosque which Mesir paste is scattered through the people. In the literature, it has been noted that there are some researches about the architectural properties of the building, but there is no research about the acoustic conditions of the mosque. The evaluation of the acoustical conditions of historical mosques considered as cultural heritage, identification of the interventions that affect the acoustical conditions adversely and improvement suggestions are important for these buildings to hand down the next generations. In this study, the history, architectural items, interior materials and measured acoustical conditions of the Sultan Mosque, which is identified as a working area, are determined and evaluated.

Full Text Available The “global economy” of the Middle Ages was created by linking the Indian Ocean trading networks with those of the Mediterranean Sea and its African and European hinterlands. These products, together with ceramics, textiles and sugar provided from Egypt and Syria, reached European markets almost exclusively through the Italian maritime republics of Amalfi, Pisa, Genoa and Venice. Especially the direction of the monsoon winds in the Indian Ocean and the course of the Venice trade ships were at the same direction. Thereby, Venice trade ships set out toward the end of August and made their way slowly through the Adriatic and the Aegean to Cyprus and Alexandria, timing their arrival there to coincide with the availability of monsoon-borne and by this way the products which are ned carried through Europe. İt is important to emphasize this subject that North Europe economy depends on this Monsoons where they became at Indian Ocean. As a maritime republic dedicated itself to the international trade, Venice was an anomaly in a feudal Europe that measured wealth by land, not money. Therefor this idea were encouraging their believing about ending the monopoly of the Muslim trade at the Indian Ocean. Ortaçağın global ekonomisini Hint Okyanusu ticaret hattı ile Akdeniz, Afrika ve Avrupa Hinterlantları arasındaki ticaret bağlantısı teşkil ediyordu. Avrupa ekonomisindeki gelişmelere paralel olarak Batı dünyasının gereksinim duyduğu ve Mısır ile Suriye’den tedarik edilen şeker, tekstil, seramik gibi ürünler Amalfi, Pisa, Ceneviz ve Venedik gibi İtalyan Cumhuriyetleri aracılığıyla Avrupa pazarlarına taşınmaktaydı. Özellikle Hint Okyanusu üzerindeki muson rüzgârlarının yönleriyle Venedik ticaret gemilerinin rotaları aynı doğrultudaydı. Bu suretle Ağustos ayının sonuna doğru İtalya’dan ayrılan gemiler, Adriyatik, Ege ve Kıbrıs rotasından İskenderiye’ye ulaştığı esnada musonlarla kar

node (Cap1. The maximum seed weight per plant also obtained from Cap2. The application of ferrous sulphate concentration with 50 ppm increased the number of three capsule nodes in plant but 100 ppm ferrous sulphate had the lowest three capsule nodes per plant. The results of interaction treatments showed that using of 50 ppm ferrous sulphate in Cap2 treatment had the maximum plant height with 89.9 cm. In two treatments Cap1 and Cap2 applying ferrous sulphate concentration with 50 ppm had the maximum number capsule per plant with 84.7 and 88.3 capsule per plant, respectively. This study showed that biosynthesis of plant metabolite was controlled not only by genetic but also by environmental conditions. Iron is an important component in many plant metabolisms such as chlorophyll and tylakoid synthesis and in development of chloroplast. Goos and Johanson, (2000 showed that two foliar applications of iron compounds (Fe-EDDHA increased yield in three soybean genotypes. Jana and Jahangir (1987 suggested that using of iron micronutrient with 0.1 ppm produced maximum height in bean. It seems that particular properties of Iron such as Redox properties, capable to establish complex with different ligands, a component of electron transport system and take part in many enzymes structure had important roles in plant metabolism and application of suitable amount can increase growth and yield of plant. Conclusions The results showed that foliar application of ferrous sulphate can increase the number of capsules per leaf node as using of 50 ppm ferrous sulfate in plants that grow up from seeds with three capsules in leaf node (Cap2 produced the most multiple capsule percent in leaf node. Maximum seed weight per plant with amount 13.2 g.plant-1 was obtained from applying 50 ppm ferrous sulfate in Cap2 plants. Positive and significant correlation was found between seed weight and multiple capsule percent in leaf node (r=0.82** and with shoot dry weight (r=0.80**. In addition, the

��sında İslam, Doğu ve dil araştırmaları ekseninde gelişen Türkoloji, günümüzde Türk’e ait ne varsa inceleyen bir bilim hâline gelmiştir. Özellikle ilk dönemlerde Türkologların dil araştırmalarına yoğunlaşması, onun bakış açısı ve yöntemlerini kullanması nedeniyle Türkolojinin sadece kavramsal olarak Türk diliyle özdeşleşmesine neden olmuştur. Bu çalışmaların etkisiyle Türkoloji, Türk dili gibi algılanmıştır. Bu çalışmanın amacı, Türkiye’deki üniversitelerin Türk Dili ve Edebiyatı Bölümü 4. sınıf öğrencilerinin “Türkoloji” kavramına ilişkin algılarını, geliştirdikleri metaforlar aracılığıyla ortaya çıkarmaktır. Araştırmanın çalışma grubunu, Türkiye Cumhuriyeti sınırlarında bulunan yedi coğrafi bölge (Marmara Bölgesi, Ege Bölgesi, Akdeniz Bölgesi, İç Anadolu Bölgesi, Karadeniz Bölgesi, Doğu Anadolu bölgesi ve Güneydoğu Anadolu Bölgesi ve bu bölgeler içerisinde bulunan 7 üniversitenin Türk Dili ve Edebiyatı Bölümü 4. sınıfında okuyan 320 öğrenci oluşturmaktadır. Araştırmanın verileri her öğrencinin “Türkoloji… gibidir, çünkü …” cümlesini tamamlamasıyla elde edilmiştir. Verilerin analiz edilmesinde ise toplanan verileri açıklayabilecek kavramlara ve ilişkilere ulaşılabilecek olan içerik analizi tekniği kullanılmıştır. Araştırmanın sonunda Türk Dili ve Edebiyatı Bölümü 4. sınıf öğrencilerinin % 87,7’sinin Türkoloji kavramına ilişkin olumlu, % 11,4’ünün olumsuz ve % 0,9’unun ise hem olumlu hem de olumsuz bir algıya sahip oldukları tespit edilmiştir. Olumlu algıya sahip öğrenciler; değer katma, disiplin, inceleme alanı; olumsuz algıya sahip öğrenciler bilimsel eksiklik, iş kaygısı, olumsuz tutum; hem olumlu hem de olumsuz algıya sahip öğrenciler ise hem olumlu hem de olumsuz tutum kodu altında toplanan metaforlar geliştirmiştir.

In our evaluation of typology, we stated four main groups according to the positions and their physical formations, then subgroups of each group were formed. [TR: Ege Bölgesi’nde, İç Batı Anadolu eşiğinde yer alan Uşak, beş ilçeye ayrılmaktadır. İlin, merkeze ve ilçelere bağlı 265 köyü vardır. 2014-2016 yıllarında il merkezine bağlı doksan köyde araştırmalar yapılmış ve 75 çeşme tespit edilmiştir. Söz konusu 75 çeşmeden sadece 12’si tescillidir. Çalışmamızda bu çeşmelerin konumları, kütle biçimlenişleri ve mimari detayları ile bir tipoloji değerlendirmesi yapılmıştır. Tipoloji değerlendirmemizde çeşmeler konum ve fiziksel biçimlenişe göre dört ana grupta toplanmış; bu gruplar kendi içlerinde alt gruplara ayrılarak değerlendirilmiştir. Uşak merkez köylerde yer alan çeşme örnekleri kütle biçimlenişi bakımından çeşitlilik gösterse de cephe özellikleri açısından tek cephe tasarımıyla dikkat çekmektedir. Fiziksel biçimlenişinde kütle, genellikle dikey dikdörtgendir. Az sayıda da olsa yatay dikdörtgen örneklere de rastlanmaktadır. Cephe kompozisyonunun ana öğesi, sivri, yarım daire, basık ya da dilimli bir kemerdir. Bazı çeşmeler kemersiz olup dikdörtgen bir kütle şeklindedir. Cephe kompozisyonunda kemerlerden sonra ikinci öğe plasterlerdir. Merkez köylerindeki çeşmelerin 28’inde dikey dikdörtgen, 2’sinde yarım silindirik formlu plaster vardır. Çeşme mimarisinde cephe kompozisyonunun bir diğer elemanı ayna taşlarıdır. Bir ayna taşına sahip 22 çeşmenin 17’sinin ayna taşı devşirme mermer, 1’inin mermer ve 4’ünün kesme taştır.

integration on existing solutions. More specifically, the Open Geospatial Consortium (OGC) Web Services (OWS) specifications play a fundamental role in geospatial information sharing (e.g. in INSPIRE Implementing Rules, GEOSS architecture, GMES Services, etc.). On the Grid side, the gLite middleware, developed in the European EGEE (Enabling Grids for E-sciencE) Projects, is widely spread in Europe and beyond, proving its high scalability and it is one of the middleware chosen for the future European Grid Infrastructure (EGI) initiative. Therefore the convergence between OWS and gLite technologies would be desirable for a seamless access to the Grid capabilities through OWS-compliant systems. Anyway, to achieve this harmonization there are some obstacles to overcome. Firstly, a semantics mismatch must be addressed: gLite handle low-level (e.g. close to the machine) concepts like "file", "data", "instruments", "job", etc., while geo-information services handle higher-level (closer to the human) concepts like "coverage", "observation", "measurement", "model", etc. Secondly, an architectural mismatch must be addressed: OWS implements a Web Service-Oriented-Architecture which is stateless, synchronous and with no embedded security (which is demanded to other specs), while gLite implements the Grid paradigm in an architecture which is stateful, asynchronous (even not fully event-based) and with strong embedded security (based on the VO paradigm). In recent years many initiatives and projects have worked out possible approaches for implementing Grid-enabled OWSs. Just to mention some: (i) in 2007 the OGC has signed a Memorandum of Understanding with the Open Grid Forum, "a community of users, developers, and vendors leading the global standardization effort for grid computing."; (ii) the OGC identified "WPS Profiles - Conflation; and Grid processing" as one of the tasks in the Geo Processing Workflow theme of the OWS Phase 6 (OWS-6); (iii) several national, European and

found in [4]. The Workload Management System (WMS) provides two types of resource managers. The first one will be based on Condor HTC and use Condor as a job manager for task dispatching and working nodes (for development purposes) while the second one will use GT4 GRAM (for production purposes). The WMS main component, the Grid Task Dispatcher (GTD), is responsible for the interaction with other internal services as the composition engine in order to facilitate access to the processing platform. Its main responsibilities are to receive tasks from the workflow engine or directly from user interface, to use a task description language (the ClassAd meta language in case of Condor HTC) for job units, to submit and check the status of jobs inside the workload management system and to retrieve job logs for debugging purposes. More details can be found in [4]. A particular component of the platform is eGLE, the eLearning environment. It provides the functionalities necessary to create the visual appearance of the lessons through the usage of visual containers like tools, patterns and templates. The teacher uses the platform for testing the already created lessons, as well as for developing new lesson resources, such as new images and workflows describing graph-based processing. The students execute the lessons or describe and experiment with new workflows or different data. The eGLE database includes several workflow-based lesson descriptions, teaching materials and lesson resources, selected satellite and spatial data. More details can be found in [5]. A first training event of using the platform was organized in September 2009 during 11th SYNASC symposium (links to the demos, testing interface, and exercises are available on project site [1]). The eGLE component was presented at 4th GPC conference in May 2009. Moreover, the functionality of the platform will be presented as demo in April 2010 at 5th EGEE User forum.

Full Text Available Lithuanian secondary verbs based on present stems in ‑staSummaryLithuanian has a number of deverbative formations which are clearly based on present stems, cf.: ded‑ẽklė ‘good layer (about hens’ : dẽd‑a ‘lays’, dúod‑ingas ‘open‑handed, generous’, duod‑imas ‘giving’ : dúod‑a ‘gives’, verd‑ẽnė ‘spring’ : vérd‑a ‘boils’, es‑ìmas ‘being’ : es‑ù ‘I am’, ẽs‑ti ‘it is’, tek‑ìmas ‘rising (of the sun’ : tẽk‑a ‘flows, runs; rises (the sun’ (beside tekė́ti, ‑ė́jo and tekė́jimas, lim̃p‑alas ‘sticky material’ : li‑m̃‑p‑a ‘sticks’, skrand‑nùs ‘good flyer’ : skre‑ñ‑d‑a ‘flies’, kánk‑inti(s ‘to give enough, to satisfy’ : (paka‑ñ‑k‑a ‘suffices’, té‑n‑k‑inti ‘to satisfy’ : (užte‑ñ‑k‑a ‘suffices’, trunk‑imas ‘delaying’ : tru‑ñ‑k‑a ‘lasts, delays’, etc. (Būga 1959, 446; Urbutis 1978, 191, 197; Ambrazas 1993, 21‑25.This paper presents examples of Lithuanian secondary verbs based on present stems in ‑sta, cf. pýkst‑auti ‘to be angry’ : pỹkst‑a ‘is angry’. These formations represent a rare (archaic? derivational process and they can be used to support the hypothesis of the deverbative origin of suffix ‑styti (Latvian ‑stīt. The proponents of this hypothesis believe that present stems in ‑sta provided bases for some formations in ‑yti (‑o, ‑ė which were later resegmented and gave rise to new suffix ‑styti (‑sto, ‑stė, cf.: lankst‑ýti : liñkst‑a → lank‑stýti : leñk‑ti (Ul’janov 1888, 210; Leumann 1942, 125; Vaillant 1966, 364; Smoczyński 1987, 203. On the other hand, the data presented in this paper still do not exclude the possibility of denominal origin of ‑styti (Leskien 1884, 443; Johanson 1893, 502; Endzelin 1922, 641; Skardžius 1943, 538; Stang 1942, 149; cf.

Mevcut öğretim programları özelde matematik ve geometri öğretim programları incelendiğinde en önemli öğrenme materyalinin etkinlikler olduğu görülmektedir (Bozkurt, 2012.

Bu sebeple öğrenme etkinliklerinin ne olduğu, hangi özellikleri barındırması gerektiği, nasıl tasarlanacağı ve uygulanacağı üzerinde durulması gereken konulardır (Uğurel ve ark., 2010.

Öğretmen adaylarının bir dizi uygulama sonucunda kendilerine verilen şablona uygun geliştirdikleri etkinlik örnekleri seçilen konu-tasarlanma amacı ve uygulama biçimine göre doküman analizine tabi tutulmuştur. Yapılan incelemenin sonucunda öğretmen adaylarının etkinlik tasarımında daha çok matematik öğretim programındaki konuları ele aldığı bu konuların farklı sınıf seviyelerinden olduğu görülmüştür. Amaç bileşeni adı altında yapılan inceleme sonucunda ise geliştirilen etkinliklerin en çok bir öğrenmeyi gerçekleştirme amacını taşıdığı bunu ise öğrenilen kavram(ları pekiştirmenin izlediği görülmüştür.

So, what can be the properties of an environmental education program?Four books are reviewed in this issue. The first one is about belogs to me and my colleague Dr. N. Serdar Sever. The book is titled as THE CHALLENGES FOR MARKETING DISTANCE EDUCATION IN ONLINE ENVIRONMENTAn Integrated Approach reviewed by Reviewed by Natalija LEPKOVA, from Lithuania. The book is purposed of role of marketing and to understand trends in the field and customer needs in a global marketplace. In this case the customers are students and they could be called as a “kings” of the market. This is a challenge with online learning because the field is in a constant state of development. Marketing online education programs is becoming more of a necessity as global competition increases. To be on time and in a right place­­­-this is the target of distance learning marketing. The second one about “Economics of Distance and Online Learning Theory, Practice and Research” By William BRAMBLE & Santosh PANDA. The book points to directions for the further research and development in this area, and will promote further understanding and critical reflection on the part of administrators, practitioners and researchers of distance education.
