Informativeness of phenotypic features of connective tissue dysplasia in children with peritoneal adhesions
Authors: Melnichenko M. G. , Kvashnina A. A.
Published: September 2016

Connective tissue dysplasia can be realized with a large number of clinical variants, and accordingly, excessive postoperative adhesion formation can be considered as a manifestation of dysplastic-dependent processes. In the predominant number of surveyed children (93.8%) CTD has developed on the background of existing connective tissue dysplasia syndrome, i.e. the presence of external signs of this condition may serve as a predictor of postoperative complications of adhesions in children.Direct correlation between the number of CTD phenotypic characters and the prevalence of intra-abdominal adhesions was determined. In our view, it allows to detect children at risk of peritoneal adhesions on the basis of external features that can be identified during general examination and do not require additional time or equipment. Accordingly, the surgical treatment of children with signs of CTD syndrome requires an integrated approach and the application of measures to prevent excessive adhesion formation, including intraoperative use of anti-adhesive gels.

Reading Josephus at Vivarium? Annotations and Exegesis in Early Copies of the Antiquities
Authors: Pollard Richard Matthew
Published: September 2016

Some of the many medieval readers of Flavius Josephus’s Antiquities annotated their manuscripts of his works. This article investigates the origin of marginal notes found in early Latin copies of Josephus’s Antiquities. The notes seem to predate the extant manuscripts and may stem from notes appended to an early copy of the Latin Antiquities, c.600. Certain interests — exegetical, typological, oratorical, and iconographic — apparent in the notes may even suggest that they originated at Cassiodorus’s Vivarium. This centre produced the Latin translation of the Antiquities to which the notes are appended. These early notes, paired with some later Carolingian notes, offer a glimpse of Josephus’s medieval reception.

Supernatural Lovers, Liminal Women, and the Female Journey
Authors: Findon Joanne
Published: September 2016

Many medieval tales feature encounters between human characters and Otherworld beings. In most cases, the Otherworld visitor is female, but in the Middle Irish Cath Maige Tuired, the Middle English Sir Degaré, and in Marie de France’s Yonec, a young woman is visited by a supernatural man who seems to have been summoned by her own desires. In each case, the man impregnates her and leaves tokens to pass on to their child. Although these tales also express anxieties over dynastic succession, their depiction of intense emotional moments focalized through a female perspective suggests an interest in women’s subjectivity that is highlighted through contact with the Other.
Classical Exegesis — from Theagenes of Rhegium to Bernard Silvestris
Authors: Herren Michael W.
Published: September 2016

This article explores the methods that ancient philosophers and historians devised for the interpretation of Greek myths and examines their development in later ages. With few exceptions, poets were regarded as the authors of myths, with the result that much ancient myth exegesis was directed to authorial intention. Claims that the poets were liars were met with the defence that they wrote allegorically. Interpretation tended to be closely related to the doctrines of the philosophical schools; indeed, it was the authority of the schools that was responsible for spreading ancient methods of interpreting pagan texts to Christian interpretations of the Bible. The article examines the mental operations involved in different hermeneutic methods, with special attention given to differentiating between allegory and symbolism.
One-pot synthesis of size and shape controlled copper nanostructures in aqueous media and their application for fast catalytic degradation of organic dyes
Authors: Ebrahimzadeh Farzaneh , Fung Kuan Zong
Published: September 2016

The present investigation reports the novel chemical reduction synthesis of air resistant copper nanostructures (particles or rods) at a high concentration (up to 0.3 M) with controlled size and shape in an aqueous media. These syntheses accomplished high yields using sodium borohydride as a reducing agent, L-(+)-tartaric acid as a new surfactant and antioxidant, and polyvinylpyrrolidone (PVP) as a capping agent. The input of extra inert gases was not necessary and this method is very simple and green. Some reaction parameters, such as amount of reactants or surfactant, pH, reaction time or rate and amount of reduction reagent, were effective for control in the size and shape of the nanoparticles. Furthermore, colloidal copper nanoparticles effectively catalytically degrade methyl orange. The synthesis method reported in this work might be useful for the large-scale production of Cu nanoparticles.

Doxastic Naturalism and Hume's Voice in theDialogues
Authors: Lorkowski C. M.
Published: September 2016

I argue that acknowledging Hume as a doxastic naturalist about belief in a deity allows an elegant, holistic reading of his Dialogues. It supports a reading in which Hume's spokesperson is Philo throughout, and enlightens many of the interpretive difficulties of the work. In arguing this, I perform a comprehensive survey of evidence for and against Philo as Hume's voice, bringing new evidence to bear against the interpretation of Hume as Cleanthes and against the amalgamation view while correcting several standard mistakes. I ultimately isolate the interpretation of Philo's Reversal at the end of the Dialogues as of paramount importance, and show how my naturalistic interpretation makes this, and other notoriously difficult passages, unproblematic.
Mechanical Fault Diagnosis of High Voltage Circuit Breakers with Unknown Fault Type Using Hybrid Classifier Based on LMD and Time Segmentation Energy Entropy
Authors: Huang Nantian , Fang Lihua , Cai Guowei , Xu Dianguo , Chen Huaijin , Nie Yonghui
Published: September 2016

In order to improve the identification accuracy of the high voltage circuit breakers’ (HVCBs) mechanical fault types without training samples, a novel mechanical fault diagnosis method of HVCBs using a hybrid classifier constructed with Support Vector Data Description (SVDD) and fuzzy c-means (FCM) clustering method based on Local Mean Decomposition (LMD) and time segmentation energy entropy (TSEE) is proposed. Firstly, LMD is used to decompose nonlinear and non-stationary vibration signals of HVCBs into a series of product functions (PFs). Secondly, TSEE is chosen as feature vectors with the superiority of energy entropy and characteristics of time-delay faults of HVCBs. Then, SVDD trained with normal samples is applied to judge mechanical faults of HVCBs. If the mechanical fault is confirmed, the new fault sample and all known fault samples are clustered by FCM with the cluster number of known fault types. Finally, another SVDD trained by the specific fault samples is used to judge whether the fault sample belongs to an unknown type or not. The results of experiments carried on a real SF6 HVCB validate that the proposed fault-detection method is effective for the known faults with training samples and unknown faults without training samples.
Chemical Flooding in Heavy-Oil Reservoirs: From Technical Investigation to Optimization Using Response Surface Methodology
Authors: Le Van Si , Chon Bo
Published: September 2016

Heavy-oil resources represent a large percentage of global oil and gas reserves, however, owing to the high viscosity, enhanced oil recovery (EOR) techniques are critical issues for extracting this type of crude oil from the reservoir. According to the survey data in Oil & Gas Journal, thermal methods are the most widely utilized in EOR projects in heavy oil fields in the US and Canada, and there are not many successful chemical flooding projects for heavy oil reported elsewhere in the world. However, thermal methods such as steam injection might be restricted in cases of thin formations, overlying permafrost, or reservoir depths over 4500 ft, for which chemical flooding becomes a better option for recovering crude oil. Moreover, owing to the considerable fluctuations in the oil price, chemical injection plans should be employed consistently in terms of either technical or economic viewpoints. The numerical studies in this work aim to clarify the predominant chemical injection schemes among the various combinations of chemical agents involving alkali (A), surfactant (S) and polymer (P) for specific heavy-oil reservoir conditions. The feasibilities of all potential injection sequences are evaluated in the pre-evaluation stage in order to select the most efficient injection scheme according to the variation in the oil price which is based on practical market values. Finally, optimization procedures in the post-evaluation stage are carried out for the most economic injection plan by an effective mathematic tool with the purpose of gaining highest Net Present Value (NPV) of the project. In technical terms, the numerical studies confirm the predominant performances of sequences in which alkali-surfactant-polymer (ASP) solution is injected after the first preflushing water whereby the recovery factor can be higher than 47%. In particular, the oil production performances are improved by injecting a buffering viscous fluid right after the first chemical slug rather than using a water slug in between. The results of the pre-evaluation show that two sequences of the ASP group have the highest NPV corresponding to the dissimilar applied oil prices. In the post-evaluation, the successful use of response surface methodology (RSM) in the estimation and optimization procedures with coefficients of determination R2 greater than 0.97 shows that the project can possibly gain 4.47 $MM at a mean oil price of 46.5 $/bbl with the field scale of a quarter five-spot pattern. Further, with the novel assumption of normal distribution for the oil price variation, the chemical flooding sequence of concurrent alkali-surfactant-polymer injection with a buffering polymer solution is evaluated as the most feasible scheme owing to the achievement of the highest NPV at the highly possible oil price of 40–55 $/bbl compared to the other scheme.
Environmental Exposures and Parkinson’s Disease
Authors: Nandipati Sirisha , Litvan Irene
Published: September 2016

Parkinson’s disease (PD) affects millions around the world. The Braak hypothesis proposes that in PD a pathologic agent may penetrate the nervous system via the olfactory bulb, gut, or both and spreads throughout the nervous system. The agent is unknown, but several environmental exposures have been associated with PD. Here, we summarize and examine the evidence for such environmental exposures. We completed a comprehensive review of human epidemiologic studies of pesticides, selected industrial compounds, and metals and their association with PD in PubMed and Google Scholar until April 2016. Most studies show that rotenone and paraquat are linked to increased PD risk and PD-like neuropathology. Organochlorines have also been linked to PD in human and laboratory studies. Organophosphates and pyrethroids have limited but suggestive human and animal data linked to PD. Iron has been found to be elevated in PD brain tissue but the pathophysiological link is unclear. PD due to manganese has not been demonstrated, though a parkinsonian syndrome associated with manganese is well-documented. Overall, the evidence linking paraquat, rotenone, and organochlorines with PD appears strong; however, organophosphates, pyrethroids, and polychlorinated biphenyls require further study. The studies related to metals do not support an association with PD.
Energy Dissipation in Graphene Mechanical Resonators with and without Free Edges
Authors: Takamura Makoto , Okamoto Hajime , Furukawa Kazuaki , Yamaguchi Hiroshi , Hibino Hiroki
Published: September 2016

Graphene-based nanoelectromechanical systems (NEMS) have high future potential to realize sensitive mass and force sensors owing to graphene’s low mass density and exceptional mechanical properties. One of the important remaining issues in this field is how to achieve mechanical resonators with a high quality factor (Q). Energy dissipation in resonators decreases Q, and suppressing it is the key to realizing sensitive sensors. In this article, we review our recent work on energy dissipation in doubly-clamped and circular drumhead graphene resonators. We examined the temperature (T) dependence of the inverse of a quality factor ( Q - 1 ) to reveal what the dominant dissipation mechanism is. Our doubly-clamped trilayer resonators show a characteristic Q - 1 -T curve similar to that observed in monolayer resonators: Q - 1 ∝ T 2 above ∼100 K and ∝ T 0.3 below ∼100 K. By comparing our results with previous experimental and theoretical results, we determine that the T 2 and T 0.3 dependences can be attributed to tensile strain induced by clamping metals and vibrations at the free edges in doubly-clamped resonators, respectively. The Q - 1 -T curve in our circular drumhead resonators indicates that removing free edges and clamping metal suppresses energy dissipation in the resonators, resulting in a linear T dependence of Q - 1 in a wide temperature range.
The Role of Na/K-ATPase Signaling in Oxidative Stress Related to Obesity and Cardiovascular Disease
Authors: Srikanthan Krithika , Shapiro Joseph , Sodhi Komal
Published: September 2016

Na/K-ATPase has been extensively studied for its ion pumping function, but, in the past several decades, has been identified as a scaffolding and signaling protein. Initially it was found that cardiotonic steroids (CTS) mediate signal transduction through the Na/K-ATPase and result in the generation of reactive oxygen species (ROS), which are also capable of initiating the signal cascade. However, in recent years, this Na/K-ATPase/ROS amplification loop has demonstrated significance in oxidative stress related disease states, including obesity, atherosclerosis, heart failure, uremic cardiomyopathy, and hypertension. The discovery of this novel oxidative stress signaling pathway, holds significant therapeutic potential for the aforementioned conditions and others that are rooted in ROS.
Analysis and Compensation for Lateral Chromatic Aberration in a Color Coding Structured Light 3D Measurement System
Authors: Huang Junhui , Xue Qi , Wang Zhao , Gao Jianmin
Published: September 2016

While color-coding methods have improved the measuring efficiency of a structured light three-dimensional (3D) measurement system, they decreased the measuring accuracy significantly due to lateral chromatic aberration (LCA). In this study, the LCA in a structured light measurement system is analyzed, and a method is proposed to compensate the error caused by the LCA. Firstly, based on the projective transformation, a 3D error map of LCA is constructed in the projector images by using a flat board and comparing the image coordinates of red, green and blue circles with the coordinates of white circles at preselected sample points within the measurement volume. The 3D map consists of the errors, which are the equivalent errors caused by LCA of the camera and projector. Then in measurements, error values of LCA are calculated and compensated to correct the projector image coordinates through the 3D error map and a tri-linear interpolation method. Eventually, 3D coordinates with higher accuracy are re-calculated according to the compensated image coordinates. The effectiveness of the proposed method is verified in the following experiments.

Published: September 2016

The development of separation methods for the analysis and resolution of chiral drugs and solutes has been an area of ongoing interest in pharmaceutical research. The use of proteins as chiral binding agents in high-performance liquid chromatography (HPLC) has been an approach that has received particular attention in such work. This report provides an overview of proteins that have been used as binding agents to create chiral stationary phases (CSPs) and in the use of chromatographic methods to study these materials and protein-based chiral separations. The supports and methods that have been employed to prepare protein-based CSPs will also be discussed and compared. Specific types of CSPs that are considered include those that employ serum transport proteins (e.g., human serum albumin, bovine serum albumin, and alpha1-acid glycoprotein), enzymes (e.g., penicillin G acylase, cellobiohydrolases, and α-chymotrypsin) or other types of proteins (e.g., ovomucoid, antibodies, and avidin or streptavidin). The properties and applications for each type of protein and CSP will also be discussed in terms of their use in chromatography and chiral separations.

Published: September 2016

The measurement scales, consistency index, inconsistency issues, missing judgment estimation and priority derivation methods have been extensively studied in the pairwise comparison matrix (PCM). Various approaches have been proposed to handle these problems, and made great contributions to the decision making. This paper reviews the literature of the main developments of the PCM. There are plenty of literature related to these issues, thus we mainly focus on the literature published in 37 peer reviewed international journals from 2010 to 2015 (searched via ISI Web of science). We attempt to analyze and classify these literatures so as to find the current hot research topics and research techniques in the PCM, and point out the future directions on the PCM. It is hoped that this paper will provide a comprehensive literature review on PCM, and act as informative summary of the main developments of the PCM for the researchers for their future research.
THE METAL ABUNDANCES ACROSS COSMIC TIME (

Authors: Ly Chun , Malkan Matthew A. , Rigby Jane R. , Nagao Tohru
Published: September 2016

We present the first results from MMT and Keck spectroscopy for a large sample of

emission-line galaxies selected from our narrowband imaging in the Subaru Deep Field. We measured the weak [O iii]
λ4363 emission line for 164 galaxies (66 with at least 3σ detections, and 98 with significant upper limits). The strength of this line is set by the electron temperature for the ionized gas. Because the gas temperature is regulated by the metal content, the gas-phase oxygen abundance is inversely correlated with [O iii]
λ4363 line strength. Our temperature-based metallicity study is the first to span

Gyr of cosmic time and

dex in stellar mass for low-mass galaxies,

–9.0. Using extensive multi-wavelength photometry, we measure the evolution of the stellar mass–gas metallicity relation and its dependence on dust-corrected star formation rate (SFR). The latter is obtained from high signal-to-noise Balmer emission-line measurements. Our mass–metallicity relation is consistent with Andrews & Martini at

, and evolves toward lower abundances at a given stellar mass,

. We find that galaxies with lower metallicities have higher SFRs at a given stellar mass and redshift, although the scatter is large (

dex) and the trend is weaker than seen in local studies. We also compare our mass–metallicity relation against predictions from high-resolution galaxy formation simulations, and find good agreement with models that adopt energy- and momentum-driven stellar feedback. We identified 16 extremely metal-poor galaxies with abundances of less than a tenth of solar; our most metal-poor galaxy at

is similar to I Zw 18.

Published: September 2016

BACKGROUND: Liver histology remains the gold standard for assessing non-alcoholic fatty liver disease (NAFLD). Noninvasive serological markers and radiological methods have been developed to evaluate steatosis to avoid biopsy.AIM: To put cutoff value for liver enzymes that could predict non-alcoholic steatohepatitis (NASH).PATIENTS AND METHODS: This study was conducted on 54 patients (with NAFLD diagnosed by the US). Patients were subjected to history, physical, anthropometric measurements, investigations including liver enzymes, abdominal US, and liver biopsy. According to biopsy results, patients were subdivided according to NASH development. Also, biopsy results were correlated to the levels of liver enzymes.RESULTS: Forty-seven patients who were suspected to have NAFLD by sonar were confirmed by biopsy. There was a significant correlation between steatosis degree in biopsy and sonar. Correlation study between steatosis in biopsy and ALT level showed highly significant positive correlation. Correlation study between steatosis in biopsy on one side & AST and GGT on the other side showed significant positive correlation. Cutoff value for detection of NASH using ALT & AST & and GGT were 50.5, 56, 60.5 respectively with sensitivity = 95.5, 90.5, 86.4 % and specificity = 93.8, 100, 87.5%. CONCLUSION: Cut off values of liver enzymes can be combined with abdominal sonar to predict NASH.

Published: September 2016

O estado de Goiás tem dificuldades em gerir seus resíduos sólidos urbanos (RSU). Dos 246 municípios goianos, apenas 15 possuem aterro licenciado. Este cenário coloca em risco o meio ambiente e a saúde das pessoas. Dessa forma, o objetivo deste estudo foi realizar uma avaliação dos riscos que os catadores de materiais recicláveis de Anápolis, Goiás, estão expostos na atividade de triagem de resíduos. Comparando-se os riscos ocupacionais de quando atuavam no antigo aterro controlado da cidade com o atual local de trabalho, uma central de triagem. Para esta avaliação utilizaram-se os métodos da Matriz Composta e de William T. Fine, metodologias semi-quantitativas. Os resultados apontaram que os riscos ergonômicos e psicossociais, como as posturas inadequadas e esforço repetitivo, exigiam a suspensão imediata das atividades dos catadores no aterro controlado. Assim como a realocação destes profissionais para a central de triagem minimizou os riscos a que estavam expostos.

Este trabalho tem como objetivo utilizar a teoria Ator-rede, particularmente os conceitos de topologia, para formatar uma proposta de metodologia de avaliação de projetos de prospectiva estratégica. Baseia-se na proposição que o espaço-tempo do processo de tradução do futuro expressa suas características topológicas na sala prospectiva, lugar que assume condição de espaço de interações síncronas onde as redes mobilizadas participam do painel de avaliação. A abordagem é qualitativa, baseada em revisão bibliográfica e na participação e observação das experiências do caso selecionado. Como resultado, se verifica a viabilidade dos conceitos da teoria Ator-rede para análises de projetos de estudos de futuros. Também se apresentam as linhas gerais de um modelo de avaliação a ser utilizado no estudo de caso ou em outras experiências. A principal contribuição do artigo para o campo estudos de futuro é introduzir os conceitos de ontologia e topologia na discussão metodológica.
Quadro político, jurídico e técnico da gestão de resíduos sólidos nos países do BRICS
Authors: Cézar Matos Arlinda , Prakash Chandak Surya , Ranga Chari Kumanduri , Godfrey Linda , Li Hui , Liubarskaia Mariia
Published: September 2016

Os países do BRICS enfrentam muitos desafios semelhantes no que tange a gestão de resíduos sólidos. Pelas apresentações e discussões do painel percebe-se que todos os países do BRICS contam com mecanismos políticos, jurídicos e técnicos adequados para apoiar a gestão integrada dos resíduos sólidos, ou seja, gestão aprimorada e redirecionamento dos resíduos dos aterros sanitários para a prevenção, reutilização, reciclagem e recuperação.  As políticas e a legislação geralmente baseiam-se no direito constitucional básico dos cidadãos a um ambiente seguro e saudável. Entretanto, embora exista legislação extensa em cada um desses países, a sua aplicação permanece problemática. Para isso contribui o fato de a gestão de resíduos sólidos, assim como as questões ambientais mais amplas, continuar tendo baixa prioridade na agenda dos partidos políticos dos países. No entanto, há sinais de que o nível de percepção das questões dos resíduos por parte de políticos e líderes de governo está mudando, especialmente nos últimos 2 a 5 anos. Como os benefícios ambientais da gestão aprimorada dos resíduos em geral são insuficientes para determinar a elevação do perfil, essas mudanças de percepção em cada um dos países parecem ter sido motivadas por outros fatores, como os benefícios sociais e econômicos associados à gestão integrada dos resíduos. Instrumentos de política avançada como a responsabilidade estendida do produtor (em inglês, Extended Producer Responsibility ou EPR) ou responsabilidade compartilhada (como denominada no Brasil) já foram implantados, ou estão sendo estudados para implantação, nos cinco países. A necessidade de educação e conscientização sobre a questão dos resíduos continua sendo uma prioridade em todos os países do BRICS, englobando sociedade civil, empresas e governo.  Em termos de implementação de tecnologias alternativas de tratamento dos resíduos, embora existam oportunidades consideráveis em todos os BRICS, está claro que a adequação da tecnologia para cada país, região, cidade ou tipo específico de resíduo requer atenção cuidadosa. A adequação das tecnologias de tratamento térmico a alta temperatura, como a incineração, está sendo cuidadosamente examinada em todos os países.
Plénitude et compossibilité

La théorie leibnizienne du « conflit des possibles » était une alternative curieuse à la fois aux explications traditionnelles de la création et à l’explication cartésienne de « l’auto-assemblage » de l’univers à partir de particules matérielles. Cependant il est difficile de rendre compte du « mécanisme métaphysique » au moyen duquel les unités élémentaires, les monades, dont l’appartenance à un monde possible donné repose sur leur compossibilité, pourraient s’assembler en un ensemble de mondes discrets. L’article examine la difficulté et la question de savoir si un mécanisme métaphysique – incluant quelque divin algorithme – pourrait sélectionner des mondes contenant non seulement de l’ordre et de la beauté mais encore des esprits capables de discerner la vérité.
L’argument du « miracle perpétuel » et ses conséquences. Dispositions naturelles et action de la créature dans les derniers écrits de Leibniz
Authors: Piro Francesco
Published: September 2016

L’argument du « miracle perpétuel » est l’un des plus importants parmi ceux que Leibniz avance contre ses derniers adversaires. La première partie de cet article analyse l’invention de l’argument, ses prémisses théologiques et, enfin, les engagements qui s’imposent à Leibniz lui-même après qu’il l’a introduit. En réalité, afin d’éviter que la nature ait besoin d’un miracle perpétuel, Leibniz devra, d’un côté, introduire une conception robuste de la nature impliquant que les créatures aient leurs propres pouvoirs et que ces derniers puissent clairement être distingués de ceux de Dieu. De l’autre, Leibniz devra éviter d’attribuer aux créatures trop de pouvoirs et surtout des pouvoirs trop forts. Il s’agira ici de reconstruire dans ses grandes lignes l’exécution de cette tâche par Leibniz, en se concentrant particulièrement sur la doctrine des dispositions « naturelles » des créatures, qui revêt une importance croissante dans les derniers écrits du philosophe.
« Les antipodes du pourquoi suffisant » ou Comment rendre une fiction raisonnable ? La dispute sur l’atomisme entre Leibniz et Hartsoeker.
Authors: Rey Anne-Lise
Published: September 2016

La correspondance entre Leibniz et Hartsoeker est le théâtre d’une discussion critique de l’atomisme. Leibniz choisit d’associer la critique de l’atomisme à une discussion sur le statut des principes chimiques, fait de l’hypothèse atomiste une fiction et utilise le principe de raison suffisante comme un instrument théorique pour évaluer, puis disqualifier la position de Hartsoeker. Cet article se propose d’interroger le statut de la fiction pour Leibniz (en situant l’usage mobilisé dans la correspondance avec Hartsoeker dans l’ensemble des usages leibniziens de la fiction) et de mettre en évidence le conflit des rationalités qui se joue autour des interprétations du principe de raison suffisante, afin de montrer que la correspondance avec Hartsoeker met en évidence l’impossibilité de la concorde rationnelle.
Justification of the Choice Matrix Material of the Magnetoactive Elastomer for Working Camera-Channel Peristaltic Unit
Authors: Vasilyeva Maria A.
Published: September 2016

The article analyzes the promising polymeric materials to be used as a template in the manufacture of magnetoactive elastomers (MAEs). MAEs belong to the group of so-called smart materials; they can be used to creeate new techniques and technologies. MAEs are promising materials used to manufacture the working chamber of pumping units for the implementation of peristaltic movements in highly viscous and highly condensed substances. Environments, which is in contact with an element of MAEs, specifically high viscosity asphaltenic oil, impose substantial restrictions on the choice of the polymer matrix for its production, taking into consideration the influence of the material selected to modify the rheological properties of the resultant material. Studies of fluoropolymers basic properties have been conducted. According to their results it is concluded that fluorine-containing polymers can be used as the polymer matrix to manufacture MAEs in contact with aggressive high viscosity substances.

The sorption properties of the outer surface of carbon nanotubes with respect to lithium are studied in connection with the search for new materials for lithium battery electrodes. The regularities of the atom ensemble structure with the increased adsorbate concentration have been investigated using ab initio method of computer modeling. Carbon nanotubes (7.7) fragment containing 112 carbon and up to 50 lithium atoms was studied. It is shown that the process of the sequential filling of the nanotube surface by adsorbate consists of two stages. The first of them (the concentration of Li is less than 8 – 9 at. %): distribution of adsorbate atoms on the surface of the tube is determined by the Coulomb repulsion of lithium ions. Chemical interaction between lithium atoms becomes significant at concentration 9 at. %. It leads to the formation of structures such as trimers and tetramers of lithium.

Recently, there has been an increasing interest to the production of the non-autoclaved aerated concrete. It has a number of advantages in comparison with other materials: low power consumption of manufacturing, high fire resistance, environmental safety, bio persistence, as well as excellent insulation properties. However, its production involves a number of problems: insufficient ultimate strength, high shrinkage, high susceptibility to the parameters of technology, and the quality of raw materials. It is a well known fact that the formation of the foam concrete structure and its main running abilities are affected not only by the mortar part, but also by the chemical nature of the foaming additive, its basic physical and chemical characteristics, as well as by the parameters of foam, produced on its basis.The paper contains an assessment of availability of the technical foam production for manufacturing of the heat-insulated constructional foam at a high-speed cavitation plant involving use of fly ash from the Central heating and power plant. We used the protein and synthetic foaming agents for the work. The authors investigated the influence of process-dependent parameters of a laboratory plant on the technical foam density and foam stability coefficient in the cement paste. The physical and mechanical properties of the non-autoclaved aerated concrete produced with investigated foams are defined. The non-autoclaved aerated concrete samples with physical and mechanical properties allowing its use in production are produced.

The effect of aluminum oxide additives on the phase relations in borosilicate glass based on the system Na2O–B2O3–SiO2 was investigated by means of the thermodynamic modeling. The phase equilibrium realized in this system was obtained using software package "FactSage" (version 6.4). The effect of aluminum oxide additives on the composition of the crystalline phases and residual melt formed during the cooling of borosilicate melts has been studied. The analysis of the diagrams has allowed establishing the regions of partial and complete melting of the substance depending on the chemical composition. The analysis allows determining the temperature of the melting process of a glassy matrix material. The combination of stable borate, silicate, mixed borosilicate, aluminosilicate and boroaluminate phases were determined for a wide range of compositions and temperatures. Boundaries of the regions formation of these phases depending on the composition and the temperature were determined. It allows assessing the prospects for absorption of elements in radioactive waste immobilization. The modeling of the crystallization melts formed in the studied systems was performed.

Published: September 2016

To predict structuring and to produce Fe-Cr-Ni-Graphite-based powdered alloys with tailor-made properties, the component diffusion coefficients have been determined that allow calculating sintering or homogenizing annealing parameters of heterogeneous charge products. It has been revealed that Fe, Cr and Ni heterodiffusion coefficients are influenced not only by their own concentration, but also by structuring kinetics and the number and distribution of the graphite in charge. The electron-probe test shows the distribution of the components in the in-terparticle contact zones. Using the Motano’s, the Lubov’s and the Maksimov’s methods, the values of mutual diffusion coefficients depending on the component concentration have been determined. Using Darken’s ratios and having experimentally determined the component interparticle zones and the displacement distance, the partial heterodiffusion coefficients have been calculated. The given paper proves that the powder-component grain-size distribution alloys should be selected on the basis of relative values of the heterodiffusion coefficients.
Magnesium Dry Mixes for Outer Wall Decoration
Authors: Zimich V.V.
Published: September 2016

A promising mode of magnesia binder use in construction is dry building mixtures production. Depending on purpose they can be self-leveling, plastering, painting, primer, putty, etc. To produce those different binders, including magnesia one, can be used, depending on the desired aesthetic, environmental and anti-bacterial properties. It can be used in children's, medical, public institutions, and residential premises. The most preferable use for magnesia dry building mixes (MDBM) is as plaster for inner or outer buildings decoration. Plasters for external use have to be light, creating a ‘breathing’ coating that prevents thermal cold bridges formation, has high vapor permeability that can adjust to the equilibrium moisture content of magnesia design on the whole, has good adhesion to the coated surface and adequate frost resistance. Ordinary Portland cement and lime-silica binders are most often used for such products. Unlike materials based on these binders, magnesia products are characterized by rapid strength development under natural conditions. Therefore, the use of magnesia binders which allow obtaining high-strength, environmentally friendly and bioresistant materials for construction is particularly interesting.

Published: September 2016

Thin films of FeCuNbMoSiB have been sputtered on Corning glass substrates with thicknesses varying from 10 to 200 nm with post annealing at 450 °C and 550 °C. Annealing in the presence of the magnetic field applied along the plane of a substrate develops an uniaxial magnetic anisotropy with the in-plane easy axis. Estimation of the effective anisotropy constant from the magnetization measurements gave Keff = 3.23 kJ/m3. Structure and surface of the films were investigated with the X-ray powder diffraction (XRD), resistivity measurements, and Raman spectroscopy. XRD and resistivity analyses show that thermal annealing at 550 °C improves the crystalline fraction and Fe-Si grain size. Raman spectra identified hematite, goethite, magnetite, as well as graphite contamination of film surfaces.
