Abstract
Pseudomonas aureofaciens (30-84) is a phenazine producing bacterium and reported as asuccessful biocontrol agent of some
plant fungal pathogens. In the present study, the possibility of biological control of cotton damping-off caused by Rhizoctonia solani
(AG-4) through phenazine production by the 30-84 strain, was investigated. In the search for the development of bioformulations of
Pa (m) (PhzR–) and Pa (w) (PhzR+) strains of 30-84, four new carriers including soybean meal (SM), cottonseed meal (CM), rice bran
(RB), and talc powder (TAL) were selected. The efficacy of bacterial formulations in reducing disease incidence was evaluated in four
intervals (15, 30, 45, and 60 days after sowing), and compared with each bacterial suspension efficacy under green-house conditions.
The results revealed that organic carriers were more effective than talc powder. It was also found that all the bioformulations were
more efficient than each bacterial suspension. The most effective in reducing disease incidence was Pa (w) + RB. In contrast, Pa (m),
Pa (m) + TAL, and Pa (m) + RB did not significantly suppress the disease in comparison with the infested control. Thus, phenazine
production as a main biocontrol mechanism of P. aureofaciens (30-84) may be affected by the kind of carriers used for the bioformulation
development.

Abstract
During 2012, soil samples from commercial pistachio orchards in three major production regions include Rafsanjan (Kerman
Province, center of Iran), Damghan (Semnan Province, north-central Iran) and Feyz-Abad (Khorasan-e Razavi Province, northeastern
Iran), were assayed on Dichloran Rose-Bengal Chloramphenicol agar (DRBC) and Aspergillus flavus-parasiticus agar media to
quantify populations of Aspergillus species from the section Flavi. The mean propagule density of Aspergillus species from the Flavi
section [log10 (CFU/g soil)] was higher in Feyz-Abad (3.06, 2.88–3.24), compared to Damghan (2.55, 2.44–2.65) and Rafsanjan (2.40,
2.26–2.54). A. flavus (69.7, 65.3 and 57.9%), A. parasiticus (19.6, 25.4, and 29.3%), and A. nomius (10.7, 9.3, and 12.8%) were the predominant
species in the regions of Rafsanjan, Damghan, and Feyz-Abad, respectively. There were significant differences among sclerotia
producing isolates of A. flavus in the sampling regions (p < 0.05). The percentage of sclerotium-producing isolates of A. flavus from Rafsanjan
(14.5%) was much lower than Damghan (39.5%) and Feyz-Abad (41.4%). The A. flavus isolates from Damghan, Rafsanjan, and
Feyz-Abad were toxigenic at 53.7%, 61.6%, and 60.4%, respectively. In Rafsanjan, aflatoxin B1 (AFB1), and AFB1 + AFB2 (aflatoxin B2)
ranged from 274 to 553 ppb (393±17.11) and 394 to 3745 ppb, respectively, while AFB1, and AFB1 + AFB2 ranged from 257 to 392 ppb
(285±13.18) and 415 to 1658 ppb, respectively, in Damghan. We found 16 and 20 vegetative compatibility groups (VCGs) for 41 and
37 nit mutant producing isolates of A. flavus from Rafsanjan and Damghan, respectively. From Damghan the VCG diversity for A.
flavus isolates was greater (54%) than from Rafsanjan (39%). Because there were a few number of sclerotium-producing isolates of
A. flavus, we did not determine the relationships between sclerotium production with VCGs and/or geographical distribution in the
three pistachio production regions. This study was the first to determine the strain and VCG diversity of A. flavus soil isolates from
Iranian pistachio orchards.
Proposed Model of Predicting the Reduced Yield Axial Load of Reinforced Concrete Columns Due to Casting Deficiency Effect
Authors: Achillopoulou Dimitra , Karabinis Athanasios 
Published: January 2015

Abstract
The study deals with the investigation of the effect of casting deficiencies- both experimentally and analytically on axial yield load or reinforced concrete columns. It includes 6 specimens of square section (150x150x500 mm) of 24.37 MPa nominal concrete strength with 4 longitudinal steel bars of 8 mm (500 MPa nominal strength) with confinement ratio ωc=0.15. Through casting procedure the necessary provisions defined by International Standards were not applied strictly in order to create construction deficiencies. These deficiencies are quantified geometrically without the use of expensive and expertise non-destructive methods and their effect on the axial load capacity of the concrete columns is calibrated trough a novel and simplified prediction model extracted by an experimental and analytical investigation that included 6 specimens. It is concluded that: a) even with suitable repair, load reduction up to 22% is the outcome of the initial construction damage presence, b) the lower dispersion is noted for the section damage index proposed, c) extended damage alters the failure mode to brittle accompanied with longitudinal bars buckling, d) the proposed model presents more than satisfying results to the load capacity prediction of repaired columns.

Seasonal and interannual variations in ice melange and its impact on terminus stability, Jakobshavn Isbræ, Greenland
Authors: Cassotto Ryan , Fahnestock Mark , Amundson Jason M. , Truffer Martin , Joughin Ian 
Published: January 2015

AbstractWe used satellite-derived surface temperatures and time-lapse photography to infer temporal variations in the proglacial ice melange at Jakobshavn Isbræ, a large and rapidly retreating outlet glacier in Greenland. Freezing of the melange-covered fjord surface during winter is indicated by a decrease in fjord surface temperatures and is associated with (1) a decrease in ice melange mobility and (2) a drastic reduction in iceberg production. Vigorous calving resumes in spring, typically abruptly, following the steady up-fjord retreat of the sea-ice/ice-melange margin. An analysis of pixel displacement from time-lapse imagery demonstrates that melange motion increases prior to calving and subsequently decreases following several events. We find that secular changes in ice melange extent, character and persistence can influence iceberg calving, and therefore glacier dynamics over daily-to-monthly timescales, which, if sustained, will influence the mass balance of an ice sheet.
La Brigade canadienne de Sibérie (Vladivostok et Omsk), octobre 1918 - juin 1919
Authors: Tremblay Yves 
Published: January 2015

En 1918-1919 le Canada fournit trois contingents pour aider les forces anti-bolchéviques, dont l’un doit opérer à partir de Vladivostok. Mais ce contingent arrive tard et ne participe pas aux opérations. Deux raisons l’expliquent : d’une part, l’hostilité du cabinet à une décision prise par le Premier ministre Borden (qui était à Londres) sans consultation suffisante ; d’autre part, pendant la préparation et le transport du contingent, l’Armistice survient, ce qui rend difficilement justifiable le maintien sous les drapeaux de soldats pour une opération lointaine qui n’est pas populaire. La mission est un échec. Curieusement, le processus politique au plus haut niveau et les règles d’engagement restrictives imposées aux chefs sur place ressemblent aux conditions qui rendront difficiles les missions de paix auxquelles le Canada s’associera à partir de la fin des années 1950.
Maîtres et élèves : psychopathologie de l'enseignement
Authors: Malgat Robin , Brokmann Pierre 
Published: January 2015

Afin d’explorer les mécanismes psychopathologiques à l’œuvre dans la transmission, les auteurs se sont intéressés à un dispositif singulier : celui de l’enseignement clinique du couple maître-élève. Les auteurs mettent en évidence que l’acte de transmission nécessite d’introduire une triangulation, faisant apparaître un troisième personnage, le patient. Partant, ils examinent le jeu d’identifications honteuses auquel l’élève est confronté. Ils confrontent ce modèle à celui de l’adoption, faisant de l’enseignement un processus de nouvelle affiliation. Ils en dégagent les processus en jeu ainsi que leurs possibles échecs. Ils exposent enfin les obligations auxquelles le maître est soumis, entre maîtrise et pertes, avant d’envisager le dernier acte de transmission, au cours duquel il sera à nouveau confronté à la culpabilité, que les auteurs proposent de dépasser par l’humilité et l’humour.
Le piège de la déflation
Authors: Département analyse et prévision  
Published: January 2015

Depuis 2010, la plupart des pays industrialisés ont engagé une stratégie de réduction des déficits budgétaires. Cette stratégie a cassé la reprise naissante de l’économie mondiale et plongé à nouveau la zone euro en récession. L’austérité et la récession y furent en effet amplifiées par la crise des dettes souveraines et la forte hausse des taux d’intérêt. Si les efforts budgétaires se sont poursuivis en 2014, ils se sont néanmoins atténués dans la zone euro, ce qui avait laissé entrevoir une accélération de la croissance. La reprise escomptée ne s’est cependant pas matérialisée, à l’exception de l’Espagne. La France est restée en situation de stagnation et l’Italie en récession. Même l’Allemagne, principal moteur de la zone euro, donne des signes de ralentissement. Par conséquent, la divergence avec les États-Unis ou le Royaume-Uni devient de plus en plus grande. Même si l’austérité est moins importante en moyenne, elle reste significative pour certains pays, d’autant plus que les multiplicateurs sont élevés. En outre, si les taux nominaux ont baissé, les taux réels ont augmenté avec la chute des taux d’inflation. Enfin, l’appréciation de l’euro en 2013 a également réduit ou atténué les efforts faits pour améliorer la compétitivité dans la zone euro.	Par ailleurs, la situation des banques porte encore les stigmates de la crise comme le reflète l’augmentation des créances douteuses dans de nombreux pays. Les bilans des agents non-financiers restent également dégradés, ce qui obère les perspectives de croissance. Cette situation s’avère d’autant plus dangereuse que le risque déflationniste se précise. Les forces qui pourront conduire la zone euro vers la déflation sont à l’œuvre. Le chômage de masse contraint la dynamique des salaires. Les dévaluations internes sont encouragées car elles sont perçues comme un outil pour regagner en compétitivité et retrouver le chemin de la croissance. Elles conduisent cependant des pays fortement intégrés commercialement à s’engager dans une course sans fin et dangereuse.
Prednisolone-Induced Predisposition to Femoral Head Separation and the Accompanying Plasma Protein Changes in Chickens
Authors: Packialakshmi B. , Liyanage R. , Lay J. O. , Okimoto R. , Rath N. C. 
Published: January 2015

Femoral head separation (FHS) is an idiopathic bone problem that causes lameness and production losses in commercial poultry. In a model of prednisolone-induced susceptibility to FHS, the changes in plasma proteins and peptides were analyzed to find possible biomarkers. Plasma samples from control and FHS-susceptible birds were depleted of their high abundance proteins by acetonitrile precipitation and were then subjected to cation exchange and reverse-phase (RP) fractionations. Analysis with matrix assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF-MS) showed several differentially expressed peptides, two of which were isolated by RP-HPLC and identified as the fragments of apolipoprotein A-I. The acetonitrile fractionated plasma proteins were subjected to reduction/alkylation and trypsin digestion followed by liquid chromatography and tandem mass spectrometry, which showed the absence of protocadherin 15, vascular endothelial growth factor-C, and certain transcription and ubiquitin-mediated proteolytic factors in FHS-prone birds. It appears that prednisolone-induced dyslipidemia, vascular, and tissue adhesion problems may be consequential to FHS. Validity of these biomarkers in our model and the natural disease must be verified in future using traditional approaches. Biomarker Insights Lameness because of femoral head separation (FHS) is a production and welfare problem in the poultry industry. Selection against FHS requires identification of the birds with subclinical disease with biomarkers from a source such as blood. Prednisolone can induce femoral head problems and predisposition to FHS. Using this experimental model, we analyzed the plasma peptides and proteins from normal and FHS-prone chickens by mass spectrometry to identify differentially expressed peptides and proteins. We found two peptides, both derived from apolipoprotein A-I, quantitatively elevated and two proteins, protocadherin 15 and VEGF-C, that were conspicuously absent in FHS-susceptible birds.

Published: January 2015

Introduction Pancreatic carcinoma affecting the uncinate process is a challenging surgical condition. Several considerations affect the management plan, including the need for vascular resection and the ability to achieve a clear margin. Methods The data of 19 patients who had curative resection for pancreatic adenocarcinoma of the uncinate process were reviewed. Operative mortality and morbidity, and disease-free survival (DFS) were calculated. Results The study population included 13 male and 6 female patients with a mean age of 55 years. Nine patients (47.4%) had stage I disease, seven patients (36.8%) had stage II disease, and three patients (15.8%) had stage III disease. A total of 12 patients had Whipple procedure and 7 patients had total pancreatectomy. In total, there were 9 R0 and 10 R1 resections. Operative mortality rate was 10.5% (2/19), postoperative leakage rate was 21.1% (4/19), and wound sepsis rate was 21.1%. Median DFS was 19.2 months. Survival was superior in the Whipple procedure group than in the total pancreatectomy group (median survival 19 months vs 4 months, respectively). Vascular resection and retroperitoneal safety margin status did not affect disease relapse. Conclusion Non-metastatic pancreatic adenocarcinoma of the uncinate process should be offered R0 or R1 resection whenever technically feasible.
Hablar desde el silencio: El silencio como verdad en las narrativas de mujeres sobrevivientes
Authors: Davidovich Karin 
Published: January 2015

A partir del estudio de testimonios y entrevistas personales con ex detenidas-desaparecidas de la última dictadura militar en Argentina sostengo que, si bien todos los testimonios del horror están impregnados por la presencia del silencio, los testimonios de sobrevivientes argentinas que comienzan a surgir masivamente desde los noventa contienen dos aspectos fundamentales que los distinguen de otros. El primero es que sugieren una diferencia importante entre dos tipos de silencio, uno mudo y el otro elocuente. Y el segundo es que llaman a un interlocutor capaz de escuchar sus silencios elocuentes. De este modo los silencios en estas narrativas testimoniales no encubren una verdad, sino que son ellos mismos la verdad. La mujeres asociadas históricamente con el silencio, se presentan como las indicadas para hacer de este no lo opuesto al lenguaje, sino el lenguaje mismo como lenguaje del trauma, invitándonos a leer el silencio, a descifrarlo, a leer más allá de las palabras, a entrenar el oído para escuchar "los indicios" de la verdad, aceptando la imposibilidad de capturar el significado de estas experiencias del horror en su totalidad. Sin embargo, esta imposibilidad no implica una parálisis, un punto final, sino que llama a la necesidad de “trabajar” ese silencio, agregándole valor, con el fin de transformar tanto la identidad de la víctima como la de la sociedad misma, creando oyentes empáticos y nuevos modos de ciudadanía.
Food in Finding H.F. and Secret City by Julia Watts: The Food of Home and the Food of the Big City
Authors: Carey Allison E. 
Published: January 2015

Abstract
Food in Kentucky-born novelist Julia Watts’s novels is never merely nutrition: the food on the characters’ tables represents safety or risk, the known or the unknown, the comforts of the familiar, or the pleasures and discomforts of expanding horizons. In Finding H.F., as part of a journey of self-discovery and coming-of-age, H.F. Simms leaves behind the familiarity of her memaw’s beans and cornbread for the Chinese food of Atlanta and the fried shrimp of the Gulf Coast. In Secret City, Ruby Pickett and her family move to the government’s "Secret City" of Oak Ridge, Tennessee, so that Ruby’s daddy can help with the war effort, and they bring with them the recipes and foodways of their home in Whitley County, Kentucky. Yet as Ruby comes of age, she, too, experiences her world expanding through new foods such as mushroom consomme and tomato aspic. This essay examines how one Kentucky novelist has employed Appalachian food and foodways as metaphors of her characters’ personal journeys of discovery.

Published: January 2015

Abstract
The purpose of this study was to investigate the test anxiety, epistemological beliefs and problem solving among students. The target population of the current research was all the students of University of Sistan and Baluchestan in the academic year 2013–2014 and the number of the sample was 375. They were selected using a classified and simple random method. The main tools to collect data were three questionnaires. The test anxiety questionnaire by Abolqasemi et al. (1996), epistemological beliefs questionnaire by Schommer (1998), and Patio problem-solving questionnaire (2002) were used. The reliability of these questionnaires was calculated through Cronbach’s Alpha test as 0.93, 0.75 and 0.88. To test the research questions, single sample t-test, independent t and Pearson correlative coefficient were adopted using SPSS software, version 20. The results showed that students have relatively high-test anxiety. It was also shown that they have relatively good epistemological beliefs. The students’ status to solve the problems is also satisfactory to some extent. There is a positive and significant relationship between test anxiety and epistemological beliefs at low level. But no statistically meaningful relationship was noticed between test anxiety and problem solving. Meanwhile the results showed that there is a negative and meaningful relationship at low level between epistemological beliefs and problem solving.
Extending the long‐term record of volcanic SO2 emissions with the Ozone Mapping and Profiler Suite nadir mapper

Published: January 2015

AbstractUninterrupted, global space‐based monitoring of volcanic sulfur dioxide (SO2) emissions is critical for climate modeling and aviation hazard mitigation. We report the first volcanic SO2 measurements using ultraviolet (UV) Ozone Mapping and Profiler Suite (OMPS) nadir mapper data. OMPS was launched on the Suomi National Polar‐orbiting Partnership satellite in October 2011. We demonstrate the sensitivity of OMPS SO2 measurements by quantifying SO2 emissions from the modest eruption of Paluweh volcano (Indonesia) in February 2013 and tracking the dispersion of the volcanic SO2 cloud. The OMPS SO2 retrievals are validated using Ozone Monitoring Instrument and Atmospheric Infrared Sounder measurements. The results confirm the ability of OMPS to extend the long‐term record of volcanic SO2 emissions based on UV satellite observations. We also show that the Paluweh volcanic SO2 reached the lower stratosphere, further demonstrating the impact of small tropical volcanic eruptions on stratospheric aerosol optical depth and climate.
Flow rate dictates permeability enhancement during fluid pressure oscillations in laboratory experiments
Authors: Candela Thibault , Brodsky Emily E. , Marone Chris , Elsworth Derek 
Published: January 2015

AbstractSeismic waves have been observed to increase the permeability in fractured aquifers. A detailed, predictive understanding of the process has been hampered by a lack of constraint on the primary physical controls. What aspect of the oscillatory forcing is most important in determining the magnitude of the permeability enhancement? Here we present laboratory results showing that flow rate is the primary control on permeability increases in the laboratory. We fractured Berea sandstone samples under triaxial stresses of tens of megapascals and applied dynamic fluid stresses via pore pressure oscillations. In each experiment, we varied either the amplitude or the frequency of the pressure changes. Amplitude and frequency each separately correlated with the resultant permeability increase. More importantly, the permeability changes correlate with the flow rate in each configuration, regardless of whether flow rate variations were driven by varying amplitude or frequency. We also track the permeability evolution during a single set of oscillations by measuring the phase lags (time delays) of successive oscillations. Interpreting the responses with a poroelastic model shows that 80% of the permeability enhancement is reached during the first oscillation and the final permeability enhancement scales exponentially with the imposed change in flow rate integrated over the rock volume. The establishment of flow rate as the primary control on permeability enhancement from seismic waves opens the door to quantitative studies of earthquake‐hydrogeological coupling. The result also suggests that reservoir permeability could be engineered by imposing dynamic stresses and changes in flow rate.
Wave breaking and turbulence at a tidal inlet
Authors: Zippel Seth , Thomson Jim 
Published: January 2015

AbstractField measurements collected with surface drifters at New River Inlet (NC, USA) are used to characterize wave breaking and turbulence in the presence of currents. Shoreward wave evolution is affected by currents, and breaking is observed in deeper water with opposing currents (ebb tides) relative to the following currents (flood tides). Wave dissipation models are evaluated with observed cross‐shore gradients in wave energy flux. Wave dissipation models that include the effects of currents are better correlated with the observations than the depth‐only models. Turbulent dissipation rates measured in the breaking regions are used to evaluate two existing scaling models for the vertical structure and magnitude of turbulent dissipation relative to wave dissipation. Although both describe the rapid decay of turbulence beneath the surface, exponential vertical scaling by water depth is superior to power law vertical scaling by wave height.
