Authors: Przemieniecki Sebastian Wojciech , Kurowski Tomasz Paweł , Korzekwa Karol , Karwowska Anna 
Published: January 2015

Abstract
The roots of winter wheat plants, cv. Mikon, grown in 45-year monoculture, were analysed in the study. Twenty-two bacterial
isolates obtained from the rhizosphere, rhizoplane, and endorhizosphere that were capable of growth at 8°C and at 28°C, were selected
for further analysis. The isolated psychrotrophs accounted for 25% of all bacteria present in the wheat rhizosphere and capable
of growth at 8°C. Psychrotrophic bacteria were analysed at a temperature of 10°C and 28°C to determine their ability to inhibit the
growth of pathogenic fungi, solubilise mineral phosphates, and to determine their ability to degrade chitin and cellulose. Similarity
between the isolates was determined by Enterobacterial Repetitive Intergenic Consensus – Polymerase Chain Reaction (ERIC-PCR)
and Random Amplification of Polymorphic DNA – Polymerase Chain Reaction (RAPD-PCR). The majority of isolated psychrotrophs
inhibited the growth of pathogenic fungi and solubilised mineral phosphates at both incubation temperatures. Psychrotrophic bacteria
exerted a two-fold stronger inhibitory effect on mycelial growth at 10°C than at 28°C. The growth of Fusarium culmorum and
F. oxysporum was inhibited to the highest extent at 10°C and at 28°C, respectively. Phosphate solubilisation rates were higher at 28°C,
particularly in the rhizosphere. Regardless of temperature, the bacteria exhibited low chitin-degrading potential, and none of the isolates
was capable of degrading cellulose. A high similarity between the selected psychrotrophs was revealed by ERIC-PCR and RAPD-
-PCR analyses. Based on RAPD-PCR, the analysed population was divided into a group of isolates obtained from the rhizosphere,
and two groups comprising representatives of both the rhizoplane and the endorhizosphere. Due to their ability to grow over a wide
temperature range and increase phosphorus availability to plants, and their antagonism against pathogens, psychrotrophic bacteria
can be used to improve the growth and yield of cereal crops.
Elbe River Waterway – Economic and Social Benefits
Authors: Bínová Helena 
Published: January 2015

Abstract
For a very long time the river Labe belongs to the transport ways with an unmistakable impact. Along the river Labe as well as along other inland water ways the commerce was spread and the towns lying on the river of Labe got the state of Hanza towns.. In the first half of the 19th century the railways transport in corridor Hamburg - Berlin - Dresden - Ústí nad Labem - Praha began competing with the water transport in this relation. So far the water cargo transport in this relation did not have competition. At present the water transport is on the edge of interest from the side of the government, investors and transporters. The reasons are clear. That is why that the infrastructure quality does not respond the transport requirements for the 21th century, the highway and railway networks are not finished, the trimodal reloading terminals absence. Usually that is why the inland water transport is not included into the logistic processes

Estimate of the total volume of Svalbard glaciers, and their potential contribution to sea-level rise, using new regionally based scaling relationships
Authors: Martín-Español A. , Navarro F.J. , Otero J. , Lapazaran J.J. , Błaszczyk M. 
Published: January 2015

AbstractWe present a set of new volume scaling relationships specific to Svalbard glaciers, derived from a sample of 60 volume–area pairs. Glacier volumes are computed from ground-penetrating radar (GPR)-retrieved ice thickness measurements, which have been compiled from different sources for this study. The most precise scaling models, in terms of lowest cross-validation errors, are obtained using a multivariate approach where, in addition to glacier area, glacier length and elevation range are also used as predictors. Using this multivariate scaling approach, together with the Randolph Glacier Inventory V3.2 for Svalbard and Jan Mayen, we obtain a regional volume estimate of 6700 ± 835 km3, or 17 ± 2 mm of sea-level equivalent (SLE). This result lies in the mid- to low range of recently published estimates, which show values as varied as 13 and 24 mm SLE. We assess the sensitivity of the scaling exponents to glacier characteristics such as size, aspect ratio and average slope, and find that the volume of steep-slope and cirque-type glaciers is not very sensitive to changes in glacier area.
Critical connections: personal learning environments and information literacy
Authors: Hicks Alison , Sinkinson Caroline 
Published: January 2015

Personal learning environments (PLEs) and critical information literacies (CILs) are two concepts that have been presented as responses to the challenges of the rich and complex information landscape. While both approaches support learners’ critical engagement with new information environments, each was developed within a different field. This paper connects and contrasts PLEs and CILs in order to explore the design of pedagogical responses to the information environment. Through a careful examination of PLE and CIL literature, the paper demonstrates that information literacy education intersects with the concepts and goals of PLEs. As such, the authors suggest that PLE scholarship informed by CIL scholarship, and vice versa, will yield a deeper understanding of modern learning contexts as well as a more holistic and responsive learner framework. The example of the research assignment will be used to demonstrate the viability of this approach. With these propositions, the authors invite educators, librarians and information technologists to engage in a dialogue about these concepts and the potential for pedagogical change.Keywords: personal learning environments; information literacy; information landscape; self-directed learningCitation: Research in Learning Technology 2015, 23: 21193 - http://dx.doi.org/10.3402/rlt.v23.21193
Exclusivismo político y religioso de los Eupátridas en Atenas arcaica
Authors: Valdés Guía Miriam 
Published: January 2015

L'exclusivité politique et religieuse des Eupatrides dans l'Athènes archaïque.
Les Eupatrides sont un groupe de familles aristocratiques attachées, pendant la période archaïque, à une portion du territoire de l’Attique constituée par l’asty/Pedion. Ils sont définis comme étant ceux qui sont rattachés à la maison du basileus (Anecd. Gr. I, 257 Bekker). Dans cet article, il s’agit d’explorer les voies de la consolidation de leur pouvoir politique et religieux dans le cadre d’une concurrence avec d’autres groupes aristocratiques d’Attique, alors qu’ils exercent de manière exclusive des cultes et des rites importants (comme les sacerdoces acropolitains par exemple), qu’ils contrôlent certaines institutions politiques et certains rituels liés aux pratiques funéraires au VIIe s. av. J.-C. Il s’agit, en outre, d’explorer les indices de changement au début du VIe s. à travers une certaine diversification dans la pratique religieuse et dans l’intégration de nouveaux agents. C’est dans cette perspective que l’on peut comprendre la tentative de Solon d’ouvrir le pouvoir politique et religieux à d’autres aristocrates tout en conservant aux Eupatrides certains privilèges alors que la pratique religieuse s’institutionnalise, devient publique et civique et s’ouvre au démos.
La représentation de la pantomime dans les romans grecs et latins : les exemples de Longus et d’Apulée
Authors: Robert Fabrice 
Published: January 2015

The representation of the pantomime in the Greek and Roman novels: the exemples of Longus and Apuleius.
Longus’ Daphnis and Chloe and Apuleius’ Metamorphoses contain two descriptions of pantomimes. The study of these episodes aims to show that the many distortions between these novelistic representations and the reality of the pantomimic shows are not meaningless. Indeed they respond to literary stakes and reveal the intentions of the authors : the original elements can be explained within the narrative framework and contribute to the construction of the meaning that should be given to the episodes themselves and to the destiny of the characters.
Colonisation et structures agraires dans l’Italie républicaine : autour du transfert des Ligures Apuani (181 av. J.-C.)
Authors: Pagé Marie-Michelle 
Published: January 2015

Colonisation and agrarian structures in Republican Italy: about the transfer of the Ligurians Apuani (181 B.C.).
In 181 B. C., the Roman power decided to transfer 47 000 Ligurians Apuani in the Samnium area. This article focuses mainly on the idea that this move was in some way a type of Roman colonisation and, based on this point of view, will explore the questions of land occupation and exploitation, as well as the transformations of the general organisation of the city of the Ligures Baebiani, created after such relocation. The general analysis mostly shows the agrarian structures of that city, like the types of resources management it had put into light, have been adapted to a particular colonial context, linked in that case to a compelled movement of population, and have somewhere succeeded to last.
Religion étrusque et droit romain d’après le bureau central des géomètres de la dynastie valentino-théodosienne
Authors: Peyras Jean 
Published: January 2015

Etruscan religion and Roman law according to the land surveyors' central office during the Valentino-Theodosian dynasty.
The documents from the Land surveyors’ Central Office at Rome are an important source in order to know the influence of the Disciplina Etrusca on Roman law and Land surveyors’ practice. They are more accurate than other evidence because they give information which can be dated (Vegoia’s Prophety against the Gracchian politics, constitution of types of limites between Italy and the ager Gallicus, establishment of very ancient colonies) and situated (types and evolution of limites in such and such colonial space). They show that the Disciplina Etrusca
was at the origin of the holiest limites, which are connected with Rome and Roman citizens’ colonies. They affirm it instructed that temples and limites should be facing west, that possessiones were made sacred since they came from a divine property or had their origin in a sacred wood.
El Boom y el fracaso de los intelectuales. Sobre "Conversación en la Catedral" (1969) de Vargas Llosa y "Cien años de soledad" (1967) de García Márquez
Authors: Alonso Mercedes 
Published: January 2015

El debate en torno al papel de los intelectuales tiene un lugar central en el Boom de la Literatura Latinoamericana. Por un lado, porque es un momento en que los escritores saltan a la esfera pública e intervienen en ámbitos que exceden o literario. Por otro, porque ha sido uno de los temas que ha ocupado a la crítica en su afán de adscribir el fenómeno al mercado o a las circunstancias políticas de América Latina.Bajo el supuesto de esa centralidad, el presente artículo busca desentrañar las representaciones del intelectual que aparecen en dos novelas del período: Conversación en la Catedral (1969) de Mario Vargas Llosa y Cien años de soledad (1967) de Gabriel García Márquez. En ellas aparecen elementos y problemáticas presentes en los debates que les son contemporáneos con una mirada más amplia que la que opone al escritor y el político (o al intelectual y el revolucionario). Las tareas propias del letrado y la relación con la esfera pública y con las masas definen a los dos personajes principales a partir de los que se puede reconstruir una definición del intelectual.
Prevention and Management of Infusion-Associated Reactions in the Comparison of Alemtuzumab and Rebif® Efficacy in Multiple Sclerosis (CARE-MS) Program
Authors: Caon Christina , Namey Marie , Meyer Cathy , Mayer Lori , Oyuela Pedro , Margolin David H. , Rizzo Marco 
Published: January 2015

Background: Alemtuzumab is a humanized monoclonal antibody approved in several countries for treatment of relapsing-remitting multiple sclerosis (RRMS). This report summarizes the experience with infusion-associated reactions (IARs) in two phase 3 trials of alemtuzumab in RRMS and examines skilled nursing interventions in IAR prevention and management.
Methods: In the Comparison of Alemtuzumab and Rebif® Efficacy in Multiple Sclerosis (CARE-MS) studies, patients with RRMS (treatment naive [CARE-MS I] or with inadequate response [defined as at least one relapse] to previous therapy [CARE-MS II]) received intravenous infusions of alemtuzumab 12 mg/day on 5 consecutive days at baseline and on 3 consecutive days 12 months later. Patients were monitored for IARs during and after each infusion. An IAR was defined as any adverse event occurring during any infusion or within 24 hours after infusion.
Results: The IARs affected 90.1% of patients receiving alemtuzumab. The most common IARs were headache, rash, pyrexia, nausea, and flushing; most were mild to moderate in severity. Management of IARs consisted of infusion interruption or rate reduction, pharmacologic therapies, and continual patient education and support. Medication administration before and during alemtuzumab infusion reduced IAR severity. Forty-five of 972 alemtuzumab-treated patients (4.6%) required interruption of the first treatment course (ie, infusions did not occur on consecutive days); of these, 24 (53.3%) were still able to complete the first and second full treatment courses.
Conclusions: Nurses played an invaluable role in the detection and management of IARs in the CARE-MS studies. Best practices for management of IARs associated with alemtuzumab include patient and caregiver education, medication to lessen IAR severity, infusion monitoring, and discharge planning.
ENHANCEMENT OF SPILLED OIL BIODEGRADATION BY NUTRIENTS OF NATURAL ORIGIN
Authors: Basseres Anne , Eyraud Patrick , Ladousse Alain , Tramier Bernard 
Published: January 2015

ABSTRACT
Ten years ago, Elf Aquitaine began developing the technologies for the acceleration of hydrocarbon biodegradation. The continuation of this work has involved the study of new additives to complement the oleophilic nutrient, INIPOL EAP 22.
In particular, it has been shown in both laboratory and in situ tests that hydrocarbon degradation can be accelerated by animal meals, which are natural products. Preliminary laboratory studies carried out under batch conditions, have shown that the use of these products has resulted in considerable growth of the bacteria, coupled with a notable increase in the biological degradation kinetics of the hydrocarbons. These results are comparable with the performance of the nutrient INIPOL EAP 22.
In situ experiments undertaken on soils polluted by hydrocarbons have shown that by using animal meals, 50 percent biodegradation was obtained after six weeks and this increased to 80 percent when mechanical aeration was also employed. Under nutrient-free control conditions, 25 percent biodegradation was obtained with no aeration and 35 percent with mechanical aeration. In trials using coastal sandy sediments, the use of these nutrients has resulted in an increase of both the number of hydrocarbon specific bacteria and the hydrocarbon degradation.
It can be concluded from these pilot experiments that in the development of bioremediation as an operational tool in the response to accidental oil spills, these nutrients of natural origin represent an interesting advance.

ABSTRACT
A group of 25 agencies from Canada and the United States conducted a major offshore burn experiment near Newfoundland, Canada. Two lots of oil, about 50 cubic meters (50 tons) each, were released into a fireproof boom. Each burn lasted over an hour and was monitored for emissions and physical parameters. Over 200 sensors or samplers were employed to yield data on over 2000 parameters or substances. The operation was extensive; more than 20 vessels, 7 aircraft and 230 people were involved in the operation at sea.
The quantitative analytical data show that the emissions from this in-situ oil fire were less than expected. All compounds and parameters measured more than about 150 meters from the fire were below occupational health exposure levels; very little was detected beyond 500 meters. Pollutants were found to be at lower values in the Newfoundland offshore burn than they were in previous pan tests.
Polyaromatic hydrocarbons (PAHs) were found to be lower in the soot than in the starting oil and were consumed by the fire to a large degree. Particulates in the air were measured by several means and found to be of concern only up to 150 meters downwind at sea level. Combustion gases including carbon dioxide, sulphur dioxide, and carbon monoxide did not reach levels of concern. Volatile organic compounds (VOCs) were abundant, however their concentrations were less than emitted from the nonburning spill. Over 50 compounds were quantified, several at levels of concern up to 150 meters downwind. Water under the burns was analyzed; no compounds of concern could be found at the detection level of the methods employed. Toxicity tests performed on this water did not show any adverse effect. The burn residue was analyzed for the same compounds as the air samples. Overall, indications from these burn trials are that 150 meters or farther from the burn source emissions from in-situ burning are lower than health criteria levels.

AbstractThe radiative properties of soot particles depend on their morphology and mixing state, but their evolution during transport is still elusive. Here we report observations from an electron microscopy analysis of individual particles transported in the free troposphere over long distances to the remote Pico Mountain Observatory in the Azores in the North Atlantic. Approximately 70% of the soot particles were highly compact and of those 26% were thinly coated. Discrete dipole approximation simulations indicate that this compaction results in an increase in soot single scattering albedo by a factor of ≤2.17. The top of the atmosphere direct radiative forcing is typically smaller for highly compact than mass‐equivalent lacy soot. The forcing estimated using Mie theory is within 12% of the forcing estimated using the discrete dipole approximation for a high surface albedo, implying that Mie calculations may provide a reasonable approximation for compact soot above remote marine clouds.
Crustal shear wave velocity and radial anisotropy beneath the Rio Grande rift from ambient noise tomography
Authors: Fu Yuanyuan V. , Li Aibing 
Published: January 2015

AbstractShear wave velocity and radial anisotropy beneath New Mexico are obtained from ambient seismic noise tomography using data from the Transportable Array. Besides the distinct seismic structure imaged across the Rio Grande rift from the Colorado Plateau to the Great Plains, both velocity and anisotropy models also reveal significant variations along the rift. The rift at Albuquerque is characterized by remarkably low velocity in the shallow crust, high velocity and strong positive anisotropy in the middle and lower crust, and low velocity in the upper mantle. These observations can be interpreted as magma accumulation in the shallow crust and significant mafic underplating in the lower crust with abundant melt supply from the hot mantle. We propose that the Albuquerque region has recently been experiencing the most vigorous extensional deformation in the rift. Positive anisotropy with Vsh > Vsv appears in the central and southern rifts with a stronger anisotropy beneath younger volcanoes, reflecting layering of magma intrusion due to past and recent rifting activities. The low velocities in the uppermost mantle are observed under high‐elevation places, the Jemez Lineament, northern rift, and east rift boundary, implying that the buoyancy of hot mantle largely compensates the local high topography. Low mantle velocities appear at the boundary of the southern rift, corresponding to the large lithosphere thickness change, instead of the rift center, consistent with the prediction from the small‐scale, edge‐driven mantle convection model. We conclude that the edge‐driven upper mantle convection is probably the dominant mechanism for the recent and current rifting and uplift in the Rio Grande rift.
Ice‐melt rates by steam condensation during explosive subglacial eruptions
Authors: Woodcock D. C. , Gilbert J. S. , Lane S. J. 
Published: January 2015

AbstractSubglacial volcanism melts cavities in the overlying ice. These cavities may be flooded with meltwater or they may be fully or partially drained. We quantify, for the first time, heat transfer rates by condensation of steam on the walls and roof of a fully or partially drained subglacial eruption cavity. Our calculations indicate that heat fluxes of up to 1 MW m−2may be obtained when the bulk vapor in the cavity is in free convection. This is considerably smaller than heat fluxes inferred from ice penetration rates in recent subglacial eruptions. Forcing of the convection by momentum transfer from an eruption jet may allow heat fluxes of up to 2 MW m−2, consistent with values inferred for the Gjálp 1996 subglacial eruption. Vapor‐dominated cavities in which vapor‐liquid equilibrium is maintained have thermal dynamic responses that are an order of magnitude faster than the equivalent flooded cavities.
