The Function of Fiction: King Edward I, King Arthur and Velthem’s Continuation
Authors: Summerfield Thea 
Published: November 2015

Abstract:
In his Continuation of a voluminous ‘Mirror of History’, written in Middle Dutch between c. 1315 and 1317, Lodewijk van Velthem describes a number of festivities and exploits in which the recently deceased King Edward I becomes closely associated with the King Arthur of romance and legend. Despite obvious flaws in Velthem’s rendition of English history and clearly fictive elements, the idea that King Edward I was ‘an Arthurian enthusiast’ who indulged in recreating Arthurian romances as part of particular festivities has become widespread, even though archival evidence to support this view has always been lacking. In my article I propose a closer look at the remarkably coherent, interlaced Edwardian/Arthurian account within the Continuation, parts of which have been consistently ignored in modern scholarship. By adopting a contextual approach it is possible to understand the function of the fictionality of the narrative, its close links with Middle Dutch Arthurian romances in Velthem’s possession and its polemical qualities.
Le cas du compilateur compilé: une

œuvre

inconnue de Rusticien de Pise et la réception de

Guiron le Courtois
Authors: Lagomarsini Claudio 
Published: November 2015

Résumé:
L’étude de l’histoire textuelle de la Compilation guironienne, une œuvre jusqu’à présent inédite que nous proposons d’attribuer à Rusticien de Pise, permet d’analyser de manière détaillée les procédés par lesquels les copistes-éditeurs des grands cycles arthuriens ont découpé et rassemblé les matériaux narratifs de leurs sources afin d’obtenir de nouveaux produits littéraires à offrir à leurs commanditaires. La première partie de l’article donne un aperçu général sur ce «nouveau» texte et examine la question de l’attribution: sont discutés ici des éléments d’ordre linguistique (présence de formes italianisantes attestées seulement chez Rusticien) et stylistique (réécriture des joutes chevaleresques de la source). Dans la seconde partie est étudiée la réception de la Compilation guironienne à l’aide du stemma codicum dressé lors des travaux préparatoires portant sur l’édition critique du texte. Comme l’œuvre est attestée dans des manuscrits italiens du xiii
e siècle ainsi que dans des témoins français plus tardifs, il est intéressant de remarquer des attitudes différenciées de la part des copistes-éditeurs face à notre compilation, qui a été démontée et réutilisée dans des contextes narratifs assez variés. Ainsi, l’étude de la structure globale des manuscrits contenant la Compilation guironienne montre que les copistes-éditeurs ont attribué à ce textedes fonctions différentes. Finalement on présente quelques observations sur un épilogue postiche ajouté dans deux manuscrits tardifs, où l’on attribue à Rusticien tout le cycle de Guiron le Courtois.
Linear approaches to resilient aggregation in sensor networks
Authors: Henry Kevin J. , Stinson Douglas R. 
Published: November 2015

Abstract
A sensor network is a network comprised of many small, wireless, resource-limited nodes that sense data about their environment and report readings to a base station. One technique to conserve power in a sensor network is to aggregate sensor readings hop-by-hop as they travel towards a base station, thereby reducing the total number of messages required to collect each sensor reading. In an adversarial setting, the ability of a malicious node to alter this aggregate total must be limited. We present three aggregation protocols inspired by three natural key pre-distribution schemes for linear networks. Assuming no more than k consecutive nodes are malicious, each of these protocols limits the capability of a malicious node to altering the aggregate total by at most a single valid sensor reading. Additionally, our protocols are able to detect malicious behavior as it occurs, allowing the protocol to be aborted early, thereby conserving energy in the remaining nodes. A rigorous proof of security is given for each protocol. We then demonstrate how to extend our linear protocols to tree-based topologies, thereby allowing linear-based approaches to be applied in a much wider range of network topologies.

Authors: Stoulil J. , Šedá P. , Anisová M. , Fencl Z. , Novák P. , Děd J. 
Published: November 2015

Abstract
The paper is focused on analyses of dark copper patina defects that were formed on one sheet under the same conditions. Roofs of ten historical buildings were studied by image analysis and samples of two roofs were subjected to more detailed destructive analysis. These samples were studied by means of scanning electron microscopy with energy dispersive X-ray spectroscopy, X-ray diffraction and infrared spectroscopy. Both types of patina are composed of brochantite. Green patinas consisted of a pure brochantite and they had a fl at and compact surface. Conversely, black patina contained a high degree of impurities (ammonia cations, nitrates, silicates) and the surface was rough. The proportion of dark patina was higher in south and east facing surfaces, where washing by rainfall is more difficult.
Parameters influencing the low-cycle fatigue life of materials in pressure water reactor nuclear power plants / Parametry ovlivòující únavové chování materiálù pro tlakovodní jaderné reaktory v režimu nízkocyklové únavy
Authors: Šefl V. 
Published: November 2015

Abstract
In this literature review we identify and quantify the parameters influencing the low-cycle fatigue life of materials commonly used in nuclear power plants. The parameters are divided into several groups and individually described. The main groups are material properties, mode of cycling and environment parameters. The groups are further divided by the material type - some parameters influence only certain kind of material, e.g. sulfur content may decreases fatigue life of carbon steel, but is not relevant for austenitic stainless steel; austenitic stainless steel is more sensitive to concentration of dissolved oxygen in the environment compared to the carbon steel. The combination of parameters i.e. conjoint action of several detrimental parameters is discussed. It is also noted that for certain parameters to decrease fatigue life, it is necessary for other parameter to reach certain threshold value. Two different approaches have been suggested in literature to describe this complex problem - the Fen factor and development of new design fatigue curves. The threshold values and examples of commonly used relationships for calculation of fatigue lives are included. This work is valuable because it provides the reader with long-term literature review with focus on real effect of environmental parameters on fatigue life of nuclear power plant materials.
Magnetite hybrid photocatalysis: advance environmental remediation
Authors: Bagheri Samira , Julkapli Nurhidayatullaili Muhd 
Published: November 2015

AbstractOne of the main public concerns is the aquatic habitat and its corresponding issues because of the incessant contamination of the ecological water systems. In recent years, research attention has been focused on processes that lead to an improved oxidative degradation of organic pollutants. Therefore, semiconductor photocatalysis technology has aroused scientists’ interest in environmental remediation. Although several semiconductors have proven to be ideal candidates for the treatment of water pollution, the efficient separation and recycling of this fine-powdered photocatalyst is still a scientific problem when applied in practice, including separation process, selectivity, and dispersion. A photocatalyst with magnetic properties allows the use of the technique of magnetic separation, which is one of the most effective and simple methods for removing suspended solids from wastewater without the need for further separation processes. The magnetic photocatalyst allows its use as a suspended material, providing the advantage to have a high surface area for reaction. This review highlights the advantages and disadvantages of current photocatalyst systems. Moreover, it focuses on hybrid magnetic photocatalysts, including metals and nonmetals, metal oxides, carbon-based materials, and ceramics.

Published: November 2015

Abstract
This article investigates the nonlinear stability of eccentrically stiffened moderately thick plates made of functionally graded materials (FGM) subjected to in-plane compressive, thermo-mechanical loads. The equilibrium and compatibility equations for the moderately thick plates are derived by using the first-order shear deformation theory of plates, taking into account both the geometrical nonlinearity in the von Karman sense and initial geometrical imperfections, temperature-dependent properties with Pasternak type elastic foundations. By applying the Galerkin method and using a stress function, the effects of material and geometrical properties, temperature-dependent material properties, elastic foundations, boundary conditions, and eccentric stiffeners on the buckling and post-buckling loading capacity of the eccentrically stiffened moderately thick FGM plates in thermal environments are analyzed and discussed.
Protective/detoxicative function of metallothionein in the rat brain and blood induced by controlled cadmium doses
Authors: Shiyntum H. N. , Ushakovа G. A. 
Published: November 2015

Cadmiumclassified as a major carcinogen is considered a poisonous and unwanted heavy metal to a lot of tissues in many organisms. Of many publications already available, the general consensus is that the cadmium attenuating element is metallothionein (MT) through its interchangeable mechanism with Zn triggered by the presence of Cd, providing binding sites for Cd ions. MT was first discovered in the kidney cortex of the horse; it represents a low molecular weight protein, rich in cysteine residues which effectively bind with metals. Its functions consist in detoxification of heavy metals like mercury, arsenic, cadmium, homeostasis of essential metals including copper and zinc, anti-oxidation against reactive oxygen species, protection against DNA damage, oxidative stress, cell survival, angiogenesis, apoptosis, and increase of proliferation. In this work, we sought to highlight the protective function of MT in the brain and serum of rats by means of detoxification under induced effects of controlled Cd doses. We have done this by exposing Wistar rats to Cd at different doses in drinking water at different time intervals. In two independent experiments, 58 rats were subjected to 0.1 or 1.0 µg Cd2+/kg of body weight for 15 or 36 days under different conditions. The obtained data indicates the different functioning systems for the brain and the blood for MT metabolism under Cd effect. Our results indicate significant loss of metallothionein level in the brain and important increases in the amount of MT in serum proving that even minimal ingestion of toxic Cd is enough to trigger the release of MT protein in blood.

Reactivation of glial cells, induced by metabolic disorders of glucose utilization and development of oxidative stress in retina under diabetes mellitus, is the key pathogenetic factor of diabetic retinopathy. Nanoparticles of C60 fullerene and some of their water-soluble derivates are known as one of the strongest antioxidants having neuroprotective effect in a number of pathologies and harmful influences. In the present study, for the first time, the effects of nanostructures of hydrated C60 fullerene (C60HyFn) on the expression and polypeptide composition of glial fibrillary acidic protein (GFAP) in retina of rats with streptozotocin (STZ)-induced diabetes have been evaluated. Using immunoblotting, 1.93-fold up-regulation of GFAP in diabetic rat retina as compared with control was shown, as a result of retinal glial cells reactivation induced by hyperglycemia. Increase in GFAP-immunolabeling associated with the reactive gliosis development in retina of diabetic rats was also confirmed by immuno-histochemical method. Consumption of C60HyFn solution (90 nM) as drinking water by diabetic rats for 12 weeks caused 1.51-fold decrease of GFAP level compared to untreated diabetic animals. In addition, C60HyFn caused statistically significant lowering of glycosylated hemoglobin concentration in blood serum of STZ-diabetic rats 1.58-fold. However, nanoparticles C60 did not affect neither insulin nor glucose levels in blood of diabetic rats. In conclusion, results obtained indicate that protective action of hydrated fullerene in the initial period of diabetic retinopathy of aged animals is realized through suppression of excessive activation of GFAP-positive retinal cells.
Short-term effect of adrenalin on S-100b and N-CAM level in the different rat brain areas
Authors: Kovalchuk Y. P. , Dovban O. O. , Kanga A. M. , Ushakovа G. A. 
Published: November 2015

The level of adrenalin grows under stress conditions, sense of danger, anxiety, fear, trauma, burns and shock. In high concentrations adrenaline increases the speed of protein catabolism. Working through the circulatory system, adrenaline affects almost all the functions of organs, causing the body mobilization to counter stressful situations. Due to ELISA the astrocytes-specific protein (S-100b) and neural cell adhesion molecule (N-CAM) were studied. S-100b is produced mainly by astrocytes іn the brain and depending on the concentration it causes trophic or toxic effect on the neurons and glial cells.Strong stress and ischemia induce re-distribution of calcium-binding protein S-100b and elevation of its level. Quantitative changes of S-100b under the influence of various factors on the body which lead to the metabolic disorder in the brain are considered today as a sign of brain damage (cortical, ischemic one, etc.). Fluctuations in the concentration of S-100b in the brain are not always accompanied by marked deterioration of the physical condition of animals, but they can also lead to a number of violations of integrative functions of the brain depending on over-production of this protein. Most N-CAM are transmembrane proteins that cross the plasma membraneonce; intracellular domains have different size and it is thought they are involved in binding to cytoskeleton or cell signaling. Violation of N-CAM functions leads to disruption of nerve sprouts. Data obtained in our study showed no serious re-distribution of S-100b and N-CAM level in the different areas of rat brain (cerebral cortex, hippocampus and thalamus) under effect of adrenalin administered to the animals (under skin) in dosage of 0.45–0.60 mg per rat, 1 time per day during 10 days, probably because of the type of injection and/or short time of adrenalin action. Increased dosage of adrenaline 1 hour before decapitation leads to the decrease of level of total protein in membrane fraction extracted from brain tissue without changing the level of S-100b and N-CAM.
The dynamics of biofilm overgrowth of Enterococcus faecalis
Authors: Synetar E. A. , Brych O. I. 
Published: November 2015

The nature of microorganisms can exist in two physiological forms that allow microbes to preserve livelihoods and continue their life cycle. The first is the population of planktonic forms of microorganisms which live freely in the environment with the developed systems of active and passive mobility, contributing to the rapid spread of a liquid medium. The second forms are those expressing specific mechanisms of adhesion, and able to aggregate on biogenic and abiogenic surfaces. Even in the deep sea vast number of species of bacteria live in their inherent horizons. Thus, the study of biofilms tube life support systems, diagnostic, laparoscopic devices during prolonged catheterization of the urinary system is of great practical, theoretical and biological significance in medicine and biology. For almost 20% of catheter-associated infections antibiotic therapy is uneffective, particularly through the formation of microbial biofilms on the surface of urinary catheters. We characterized the dynamics of biofilm growth of Enterococcus faecalis on fragments ofsilicone catheter. The study was conducted using bacteriological and electron microscopic techniques. Study of the dynamics of biofilm formation was performed using E. faecalis strain 49, which is isolated from the urine of persons who are not the patients of the urological department of resuscitation and intensive therapy. Using scanning electron microscopy we have established dynamics and phase attachment ofE. faecalis bacteria and subsequent overgrowth of silicone catheter surface. Aftercalculations, index of adhesion on the turbulent wall amounted to 0,49 microbial cells. That is, every other cell of the monolayer adhered on the catheter. Area of biofilm growth of E. faecalis after 24 hour incubation was equal to 51.5 μm2, in 48 hours it increased to 231.5 μm2. After 72 hours of incubation we recorded the increase in biofilm growth of E. faecalisto 1922,8 μm2. The results were obtained on fragments of catheters, immersed in broth in vertical position. This orientation has excluded the deposition of germs by sedimentation, i.e. by gravity. It is known that after the logarithmic phase and achieving M-concentration for a few hours microbes starttodie and their possible deposition mayoccur. Therefore, our results confirm the formation of biofilm, instead of sedimentation of dead microbes. Our study shows that biofilm is “the way of overgrowth on artificial and natural surfaces by microorganisms that are kept on them by exopolymer membranes”.

The aim of this work was to study the patterns of utilization of sulfate and nitrate ions by bacteria Desulfomicrobium sp. CrR3 and Desulfovibrio desulfuricans Ya-11 under different cultivation conditions. Chromium-resistant sulfate-reducing bacteria Desulfomicrobium sp. CrR3 and D. desulfuricans Ya-11 were used. Bacteria were grown in Posgate C medium at 30°C in 25 ml test tubes under anaerobic conditions. To test the ability of bacteria Desulfomicrobium sp. CrR3 and D. desulfuricans Ya-11 to use various substances and ions as electron acceptors, they were incubated in potassium phosphate buffer (10 mM, pH 7) with sulfate, nitrate and nitrite ions in concentrations of 1, 5 and 10 mM. At various concentrations of sulfate ions (1, 5 and 10 mM), biomass of bacteria Desulfomicrobium sp. CrR3 and D. desulfuricans Ya-11 increased with the increase of concentration of electron acceptor, the maximum biomass was equal to 3.65 and 3.05 g/l at 10 mM of sulfate ions, respectively. With the increase of concentration of nitrate ions to 5 mM the biomass increased by 70% compared to the biomass of bacteria grown in the medium with nitrate ions at the concentration 1 mM. The maximal biomass was determined in the presence of nitrate ions at a concentration of 10 mM – 3.78 and 3.15 g/l for bacteria Desulfomicrobium sp. CrR3 and D. desulfuricans Ya-11, respectively. It is found, as a result of incubation of bacteria Desulfomicrobium sp. CrR3 and D. desulfuricans Ya-11, that by introducing sulfate ions at a concentration of 5 mM bacteria Desulfomicrobium sp. CrR3 used 98%, while D. desulfuricans Ya-11 used only 86%, and under these conditions hydrogen sulfide has been detected in the incubation mixture at the concentration of 0.8–1.0 mM. In the presence of 10 mM of sulfate ions efficiency of electron acceptors utilization was equal to 85–95% for both strains. Bacteria Desulfomicrobium sp. CrR3 intensively used nitrate ions, the efficiency of electron acceptor utilization at 10 mM was equal to 92.8%, while for D. desulfuricans Ya-11 the usage percent amounted to 73% only, and nitrite ions were not observed after three days of incubation. It is established that bacteria Desulfomicrobium sp. CrR3 and D. desulfuricans Ya-11 are capable to use sulfate and nitrate ions as electron acceptors in the process of the disimilatory sulfate and nitratre reduction. As a result of the study of patterns of nitrate utilization by Desulfomicrobium sp. CrR3 and D. desulfuricans Ya-11 it is found that bacteria use nitrate as a nitrogen source for biosynthetic processes, and as electron acceptors. Under these conditions nitrates are reduced to nitrites, and then they are turned to ammonium.
