Use of Dacron prosthesis in esophageal diverticula in a dog – a case report
Authors: Muste Aurel Nicolae , Tănase Andrei , Muste Marius Mihai , Beteg Florin Ioan 
Published: September 2014

A one-and-a-half-year-old male dog of the Caniche breed was examined for repeated regurgitation episodes. At clinical examination food or liquid regurgitation episodes were reported at different times after food ingestion. The esophagus was visualized with the videoendoscope and then examined on liquid barium sulphate. The assessment revealed the existence of two cervically and mediastinally (intrathoracically) located dilatations. The surgical procedure was based on polyester vascular prostheses also used in human vascular surgery. The surgery was performed in two stages with a 4 week interval in between, without the resection of the dilated walls, with the prostheses positioned and fixed in different ways and with very good post surgery recovery. Eleven months after the surgery the dog’s health condition was very good. To our knowledge, this is the first report about these procedures which avoid the resection of a portion of the esophagus wall, thus preventing the occurrence of scars or strictures at this level, and prostheses increase the support and stability of the affected esophagus portion.

Published: September 2014

Abstract
The inspection of the sealing weld is an important phase for the evaluation of the acceptability of final disposal canister, but the weld is only a part of the 3D shielding of copper shell. The main tasks for reliable NDT evaluation requires an extensive evaluation of the parameters – which contains typical inspection related items like repeatability, S/N ratio, POD, setting up the equipment for inspection, and all practices for inspections. The other parameters are material parameters, their variation must be taken into account in the evaluation of NDT reliability. Further parameters include human factors, i. e. human inspectors and their interaction with technical systems; their effects were studied on an example of the evaluation of eddy current data. Final parameters are related to evaluation of detected defects, which means sizing and base for acceptance and this can be done in different ways. Some examples are given and results are compared with different methods for instance between radiographic testing and ultrasonic testing by raw data analysis and PA-SAFT results. Also, preliminary curves for the evaluation of metallographic results of 55 defects will be shown by EB weld measurements. Some practical items concerning copper inspections will be also discussed related to acceptability.

Authors: Basyigit Aziz Barış , Kurt Adem 
Published: September 2014

Abstract
Application fields for duplex stainless steels are drastically increasing. Industries producing and operating petrochemical process equipment, pipelines, bridges, pressure vessels, heat exchangers, rotors, and sea-water systems have a high demand for these steels. In this study, UNS S32205 duplex stainless steel plates of 3 × 40 × 145 mm were TIG welded with welding wires of W22 9 3 NL (2209). The main aim was to investigate the effects of various amounts of magnetic δ-ferrite and other important phases or intermetallic compounds that are formed during and after welding. The phase quantities differing by the welding conditions and argon shielding gas mixtures containing 0, 1, 3, 6, and 9 vol.-% N2 are studied. The investigations included Charpy V-notch impact tests, weight loss corrosion tests, and microstructural analyses according to ASTM A 923 and magnetic δ-ferrite measurements according to EN ISO 17655, and EN ISO 8249 as well as image analyses according to ASTM E-562, ASTM E 1245 for a comparision of the effect of the amounts of all phases. The differences with respect to the welding parameters were also identified.
An Investigation of TIG Welding of AZ31 Magnesium Alloy Sheets*
Authors: Demir Bilge , Durgutlu Ahmet 
Published: September 2014

Abstract
In this study, butt welding of commercial AZ31 magnesium alloy sheets has been investigated by using the tungsten inert gas welding process with alternating and pulsed current. Magnesium alloy welding, although well developed and understood, can present some problems, such as porosity, hot cracking, oxide formation, etc. Samples of the welded parts have been examined by optic microscopy and mechanic tests. Results showed that porosities and homogeneous micro size oxides were rarely found. Orientation of the weld microstructure in direction of the heat transfer were also rarely observed and equiaxed grain morphology was the dominant grain structure as in the base metals. In addition, fusion zone and HAZ of the welded samples have generally shown twins. This seems to be a very dominant grain type particularly in pulsed samples. Hot cracking was not observed in any samples. Results of mechanical tests showed that pulsed current seems to generate more favorable higher mechanical properties of weld joints than alternating current for magnesium alloys.

Published: September 2014

AbstractKnowledge of the spatial snow distribution and its interannual persistence is of interest for a broad spectrum of issues in cryospheric sciences. In this study, snow depths derived from airborne laser scanning are analyzed for interannual persistence of the seasonal snow cover in a partly glacierized mountain area (~36 km2). At the end of five accumulation periods, the snow-covered area varied by 16% of its temporal mean. Mean snow depth of the total area ranged by a factor of two (1.31–2.58 m), with a standard deviation of 0.42 m. Interannual correlation coefficients of snow depth distribution were in the range 0.68–0.84. Of the investigated area, 75% was found to be interannually persistent. The remaining area showed variable snow cover from year to year, caused by occasional avalanches and changes in surface topography as a result of glacier retreat. Snow cover underwent a change from a homogeneous distribution on the former glacier surface to a more heterogeneous snow cover in the recently deglaciated terrain. A geostatistical analysis shows interannual persistence in scaling behavior of snow depth in ice-free terrain with scale break distances at 20 m. Scale-invariant behavior of snow depth is indicated over >100 m on smooth glacier surfaces.
Services et vulnérabilité des territoires traditionnellement industriels : la spécialisation tertiaire des zones d'emploi haut-normandes
Authors: Jennequin Hugues , Mouhoub El Mouhoud 
Published: September 2014

Les forces et faiblesses des territoires face à la mondialisation ont trop souvent été évaluées au regard de leurs activités industrielles, conduisant à mener des politiques de soutien en réponse aux difficultés de ce secteur, sans toutefois freiner la désindustrialisation des régions. Le rôle des services comme moteur régional a été globalement négligé. Cet article analyse la situation de la Haute-Normandie, industrialisée et affectée par la crise, et étudie la spécialisation en services de ses zones d’emploi en s’appuyant sur une typologie récente des services (DATAR, 2010). Des atouts apparaissent (faible spécialisation dans les services les plus volatils, poids des services d’intermédiation...). Trois angles de vulnérabilité potentielle sont néanmoins préoccupants : un poids significatif des services collectifs dans un contexte national de redistribution géographique ; une faible part des services cognitifs ; la spécialisation dans les services les plus volatils de la zone la plus industrialisée (Vallée de la Bresle).
Dynamiques d'agglomération et de dispersion des activités polluantes : étude des limites des politiques environnementales
Authors: Ciucci Julien 
Published: September 2014

Dans le cadre d’un modèle centre – périphérie, nous proposons une analyse de l’influence d’une politique environnementale restrictive sur la localisation des firmes industrielles polluantes. Dans ce modèle, ce sont les choix de localisation des travailleurs qualifiés qui déterminent la répartition spatiale de ces firmes. Dans leurs choix de localisation, les travailleurs qualifiés prennent en compte des facteurs pécuniaires, tels que le salaire et l’indice des prix, mais également des facteurs non pécuniaires, plus précisément ici la qualité environnementale. Dans ce contexte, les pouvoirs publics tentent d’influer sur ces choix, par le biais d’une taxe environnementale, afin de maximiser l’utilité agrégée de leurs administrés. Ce modèle permet d’identifier les différentes forces, d’agglomération et de dispersion, qui déterminent la répartition spatiale des firmes polluantes. En outre, si les forces d’agglomération dans une région sont trop importantes, la taxe environnementale peut n’avoir aucune influence sur la répartition spatiale des firmes polluantes.

Authors: Savaris Ricardo F. , Nichols Christina , Lessey Bruce A. 
Published: September 2014

Aims The aim of this study was to identify whether endometriosis is a progressive disease with age, and to review the literature on this topic. Material and methods The incidence of endometriosis in a cohort of 500 women who underwent laparoscopy between 2003 and 2013 in the Greenville Health System, in South Carolina, United States, was reviewed. The search of the world literature on progression of endometriosis was limited to 1980 and beyond. Results The correlation between stage of endometriosis and age was found to be small (r = −0.04; 95% CI, −0.13 to 0.04; p = 0.3; n = 471). The literature search identified 16 studies on adults. Progression of endometriosis findings at laparoscopy occurred in 31% of the cases with follow-up (n = 162). Conclusions Endometriosis of minimal or mild American Society for Reproductive Medicine (rASRM) classification stage is equally likely to be present in women of all ages; similarly, endometriosis in its severe form is not age-dependent.

Purpose The aim of this study was to determine whether a polymorphism of the HSD17β1 gene (rs605059), involved in estrogen synthesis, is associated with endometriosis in Brazilian patients. Methods A case-control study was conducted in 231 women. All patients in the case group had a histopathological diagnosis of endometriosis. Genomic DNA was genotyped by nested-PCR, followed by digestion of the PCR product with the enzyme BstUI. Results The frequencies of the genotypes detected in the case and control groups were 22.4% GG, 52.2% AG and 25.4% AA; and 31.3% GG, 49.3% AG and 19.4% AA, respectively, with no significant difference between groups. The prevalence of the G allele was 48.5% and 56% in the case and control groups, respectively. No significant difference in genotype or allele frequency was detected between the different stages of endometriosis (p>0.05). Conclusions The results suggested that the Ser312Gly polymorphism of the HSD17β1 gene is not associated with endometriosis in Brazilian patients.

Published: September 2014

Abstract
White rot fungus participates in biological degradation of many organic environmental pollutants. Also, white rot fungus contains a variety of extracellular enzymes, and these enzymes are used for biological degradation of organic matter. We investigated the biological treatment of synthetic dyes, at a low cost and in the shortest possible time, that are used especially in the dye and textile industries and are important polluting agents in the wastewater discharged into the environment by these industries. For this purpose, removal of Remazol Brillant Blue by Pleurotus ostreatus and Coprinus plicatilis was studied. This dye was removed 100% (dye concentration, 10.0 mg/L) by both organisms. Laccase and manganese peroxidase enzyme activities were also monitored. There was an attempt to identify metabolites via GC/MS at the end of the decolorization. No detectable metabolite was found.

Published: September 2014

Abstract
This paper describes a method that includes an optimized extraction process and identification and quantification of two anticancer compounds (garcinol and isogarcinol) by LC/electrospray ionization (ESI)-MS/MS in the multiple reaction monitoring (MRM) mode. The study aimed to develop a fast, accurate, and sensitive method for the quantification of garcinol and isogarcinol in different extracts of Garcinia indica fruits. The compounds were detected using LC/ESI-MS/MS in the positive-ion mode and quantified in the MRM mode using a transition mass of m/z 603.3/411 taken as the quantifier and 603.3/343.2 as the qualifier for garcinol and isogarcinol. Five point calibration curves were linear in the range of 2 to 10 ng/mL for garcinol and 0.5 to 6 ng/mL for isogarcinol, with a correlation coefficient of ≥0.990 for both. LOQ for garcinol and isogarcinol was 0.06 and 0.05 ng/mL, respectively, while LOD was 0.021 and 0.017 ng/mL respectively. Our work demonstrated optimization of extraction procedure, fast and highly sensitive quantification (pg level LOQ), and validation of the developed method for the investigated compounds in fruit extracts of G. indica.
A Sensitive and Specific Hyperbranched Rolling Circle Amplification Assay and Test Strip for White Spot Syndrome Virus
Authors: Zhao Yu-ran , Yin Wei-li , Yue Zhi-qin , Li Ba-fang 
Published: September 2014

Abstract
White spot syndrome virus (WSSV) is a global threat to the prawn industry, and there is no simple method for field-based testing of this virus. We designed a padlock probe and primers to the capsid protein gene VP28 of WSSV, and established a hyperbranched rolling circle amplification (HRCA) assay and a corresponding strip-based test. The assay and the test strip both had similar high accuracy and specificity, and their sensitivity was about 10 copies/μL, which is 100 times higher than conventional PCR. In this study, 68 batches of prawns were tested for WSSV with the HRCA assay and test strip, and the results were compared with the PCR assay. The results indicated that both the assay and test strip had accuracy similar to each other and to the PCR results. However, the assay and strip were more sensitive and user-friendly than PCR. Establishment of this method will provide a rapid detection of WSSV and also a basis for field-based detection of animal disease.

Authors: Albalat Guillermo Rodríguez , Broch Begoña Bedrina , Bono Marisa Jiménez 
Published: September 2014

Abstract
Legipid®Legionella Fast Detection is a test based on combined magnetic immunocapture and enzyme-immunoassay (CEIA) for the detection of Legionella in water. The test is based on the use of anti-Legionella antibodies immobilized on magnetic microspheres. Target microorganism is preconcentrated by filtration. Immunomagnetic analysis is applied on these preconcentrated water samples in a final test portion of 9 mL. The test kit was certified by the AOAC Research Institute as Performance Tested MethodSM (PTM) No. 111101 in a PTM validation which certifies the performance claims of the test method in comparison to the ISO reference method 11731-1998 and the revision 11731-2004 “Water Quality: Detection and Enumeration of Legionella pneumophila” in potable water, industrial water, and waste water. The modification of this test kit has been approved. The modification includes increasing the target analyte from L. pneumophila to Legionella species and adding an optical reader to the test method. In this study, 71 strains of Legionella spp. other than L. pneumophila were tested to determine its reactivity with the kit based on CEIA. All the strains of Legionella spp. tested by the CEIA test were confirmed positive by reference standard method ISO 11731. This test (PTM 111101) has been modified to include a final optical reading. A methods comparison study was conducted to demonstrate the equivalence of this modification to the reference culture method. Two water matrixes were analyzed. Results show no statistically detectable difference between the test method and the reference culture method for the enumeration of Legionella spp. The relative level of detection was 93 CFU/volume examined (LOD50). For optical reading, the LOD was 40 CFU/volume examined and the LOQ was 60 CFU/volume examined. Results showed that the test Legipid Legionella Fast Detection is equivalent to the reference culture method for the enumeration of Legionella spp.

Authors: Giménez Esther Campos 
Published: September 2014

Abstract
This report documents improvement and single-laboratory validation performed on AOAC First Action Method 2011.08 for vitamin B12 in infant formula and adult/pediatric nutritional formula. The original validation study included a range of fortified products, from infant formulas to breakfast cereals or beverages. Extended validation data, including additional infant formulas and adult/pediatric nutritionals, has now been produced. In addition, the method has been modified to use ultra-HPLC and the calibration range extended in a multilevel calibration curve. Detection and quantification limits were also improved by increasing the sample weight used for analysis and the reconstitution rate adapted to the requirements. The Stakeholder Panel on Infant Formula and Adult Nutritionals Test Material Kit, designed to represent a large range of products within the category (infant formula and adult nutritionals made from any combination of milk, soy, rice, whey, hydrolyzed protein, starch, and amino acids, with and without intact protein), was used to determine performance characteristics of the method. The modifications included allow now full compliance with standard method performance requirements established for vitamin B12 (SMPR 2011.005). LOQ was ≤0.01 μg/100 g, working range between 0.01 and 5.0 μg/100 g, repeatability ≤7%, and recovery in the range 90–110%. The method was granted AOAC First Action status 2014.02.

Seeking genericity in the selection of parameter sets: Impact on hydrological model efficiency
Authors: Andréassian Vazken , Bourgin François , Oudin Ludovic , Mathevet Thibault , Perrin Charles , Lerat Julien , Coron Laurent , Berthet Lionel 
Published: September 2014

AbstractThis paper evaluates the use of a small number of generalist parameter sets as an alternative to classical calibration. Here parameter sets are considered generalist when they yield acceptable performance on a large number of catchments. We tested the genericity of an initial collection of 106 parameter sets sampled in the parameter space for the four‐parameter GR4J rainfall‐runoff model. A short list of 27 generalist parameter sets was obtained as a good compromise between model efficiency and length of the short list. A different data set was used for an independent evaluation of a calibration procedure, in which the search for an optimum parameter set is only allowed within this short list. In validation mode, the performance obtained is inferior to that of a classical calibration, but when the amount of data available for calibration is reduced, the generalist parameter sets become progressively more competitive, with better results for calibration series shorter than 1 year.
Statistical analysis of ground‐based chorus observations during geomagnetic storms
Authors: Spasojevic M. 
Published: September 2014

AbstractChorus observations from two ground‐based, Antarctic receiving stations are analyzed for a set of geomagnetic storms from 2000 to 2010. Superposed epoch analysis is performed together with statistical hypothesis testing to determine whether the observed quantities (geomagnetic indices, outer belt energetic electron fluxes, and chorus properties) are statistically significantly different as functions of storm phase, storm size, and storm type. Waves generated in the outer dayside magnetosphere and observed on the ground at South Pole Station are suppressed during main phase and are statistically unchanged from random intervals during recovery phase. Waves generated in the inner magnetosphere and observed on the ground at Palmer Station are significantly enhanced during storm main phase and for about 3 days into recovery. During main phase, there are larger enhancements in chorus occurrence, amplitude, and frequency extent as observed at Palmer during larger storms. During recovery phase, there are larger enhancements in chorus occurrence, amplitude, and frequency extent as observed at Palmer during larger storms and during storms where the average rate of electron flux increase, averaged across the outer belt, is higher.
