Authors: Terekhov A. I.
Published: January 2018

The article presents a scientometric analysis of the development of the carbon nanotechnology (NT) direction for 2000-2015 with the participation of 30 most active countries. It shows shifting the world research center to the Asian region, both on volume and quality indicators. Using the concept of a national research portfolio gives deep characteristics of different countries behavior in the course of scientific rivalry. Due to the strong skewness of the citation distributions, preference is given to the percentile-based indicators, such as: the contribution of a country to the world top-10% (top-1%) of the most highly cited publications, the share of such publications in the country's total output, the highly cited papers index, etc. Relying on them, the author fully discloses the scientific «offensive» of the «newcomer» countries on the «incumbents» ones (e.g. China on the USA, South Korea on Germany, Iran on Russia), the phenomenon of Singapore as an effective producer of highly cited publications on the carbon nanostructures, and international co-authorship in the top-1% segment of the most cited articles. Russia's positions are studied in detail, the main domestic research participants are established, and based on bibliometric criteria the center of scientific excellence in the field of graphene is identified. The paper characterizes the supporting role of a number of national science foundations in the NT carbon direction development using data of WoS. The author used the Science Citation Index Expanded database for the initial bibliographic sampling; information of science foundations of Russia and the USA, as well as patent organizations of Russia (Rospatent) and the world (WIPO) for additional comparison.

Valeological support of library-information activities in school libraries
Authors: Sokolov V. Y.
Published: January 2018

The article outlines general characteristics of the originality of forming valeological functions in a school library. The paper objective is to study peculiarities of the valeological support of library-information activities in school libraries, as well as the specifics analysis of their library and cultural-educational work aimed at developing the health culture of this activity subjects The author consistently reveals the peculiarities of forming the valeological function of school libraries under conditions of the information society development and dissemination of information-telecommunication technologies in libraries. The article describes cultural-educational activities of libraries directed to develop the health culture not only in readers (schoolchildren, their parents, teachers), but in librarians themselves. The author applies both general scientific methods of research (analysis, synthesis, deduction, induction, generalization, abstraction, comparative, structural-functional methods, method of system analysis, etc.) and special ones (method of analysis of analog objects, information processing, grouping). While researching the author concludes about necessity of the the following: to equip educational libraries technically; to update and strengthen the information base and book stocks of school libraries; to ensure the access of libraries to information resources, in particular the Internet; to form a unified electronic database of school library collections; to develop a form of resource integration with other educational libraries; to create a standing order on the status of libraries in basic schools; to develop a system for improving the skills of school library staff; to organize special training for school librarians to master their knowledge and skills of a healthy lifestyle. Therefore, the school librarian must be trained according to a separate professional specialization. The social life development requires librarians to know not only the valeology bases, but the ability to navigate in information technologies, school curricula and training courses diversitys. Modern problems of information education and forming a high level of valeological culture can be solved only by combining the efforts of general education institutions and school libraries, teachers and librarians. Pedagogical experience shows that knowledge on the health formation and preservation is a necessary and insufficient factor in students' personality development. To influence the behavior, informative methods should be combined with life skills of effective work and rest, physical activity, rational nutrition, an ability to analyze health issues and make appropriate decisions. Thus, forming health culture through library-information activities provides arming school readers and librarians with knowledge on social and individual health and applying certain information technologies in their activities.

Published: January 2018

The first part of the paper was aimed at analyzing the given nonlinear problem by different methods of computation of the Lyapunov exponents (Wolf method [1], Rosenstein method [2], Kantz method [3], method based on the modification of a neural network [4, 5], and the synchronization method [6, 7]) for the classical problems governed by difference and differential equations (Hénon map [8], hyper-chaotic Hénon map [9], logistic map [10], Rössler attractor [11], Lorenz attractor [12]) and with the use of both Fourier spectra and Gauss wavelets [13]. It was shown that a modification of the neural network method [4, 5] makes it possible to compute a spectrum of Lyapunov exponents, and then to detect a transition of the system regular dynamics into chaos, hyper-chaos, hyper hyper-chaos and deep chaos [14-16]. Different algorithms for computation of Lyapunov exponents were validated by comparison with the known dynamical systems spectra of the Lyapunov exponents. The carried out analysis helps comparatively estimate the employed methods in order to choose the most suitable/optimal one to study different kinds of dynamical systems and different classes of problems in both this and the next paper parts.
Analysis of Dark Current in BRITE Nanostellite CCD Sensors
Authors: Popowicz Adam
Published: January 2018

The BRightest Target Explorer (BRITE) is the pioneering nanosatellite mission dedicated for photometric observations of the brightest stars in the sky. The BRITE CCD sensors are poorly shielded against extensive flux of energetic particles which constantly induce defects in the silicon lattice. In this paper we investigate the temporal evolution of the generation of the dark current in the BRITE CCDs over almost 4 years after launch. Utilizing several steps of image processing and employing normalization of the results it was possible to obtain useful information about the progress of thermal activity in the sensors. The outcomes show clear and consistent linear increase of induced damage despite the fact that only about 0.14% of CCD pixels were probed. By performing the analysis of temperature dependencies of the dark current, we identified the observed defects as phosphorus-vacancy (PV) pairs, which are common in proton irradiated CCD matrices. Moreover, the Meyer-Neldel empirical rule was confirmed in our dark current data, yielding EMN=24.8 meV for proton-induced PV defects.

Authors: Demekristos Abraham
Published: January 2018

The aims of the study were to evaluate seedling growth and survival of Prunus africana provenances in awi highland based on ecological requirement of the tree. We measured survival and growth of three P.africana provenances seedlings found in Ethiopia (provenances sources namely: Gedeo, Jibat and Munnessa). Design of experiment with randomized complete block design (RCBD) with three replications. Seedlings planted at 2m, 2.5m and 3m distance between plants, plot, and blocks respectively. A plot size of 10mx10m and 25 plants are found per plot (0.01ha). We used ANOVA to test differences in survival, and growth among provenances over time. Results concluded that, provenances have no significant variation among in establishment rate, plant height and collar diameter growth. Of these provenances, Jibat was the first in establishment (56%), second in height (1.97m) and diameter (2.89cm). Gedeo was stood first in height (2.30m) but second in establishment rate (52%) and thickness(3.45cm), but Munessa with very good growth in diameter(3.59cm) might be prefreed for bark extraction followed by Gedeo, last in height (1.75m),but established second (52%). Contrary to expectations, seedlings were still at substantial risk of mortality ≥3 years after planting. Probably the plants survival rate and growth probably affected by altitude, soil water potential, light exposure, and wild animal presence in the surrounding. In steep slope sites, canopy shade, existing weed vegetation as well as wild animals such as apes is unlikely to enhance seedling survival after planting. Our results suggest that seedling mean growth increased with 0.008mm thickness and 0.41mm per day while 2.8mm thickness and 146.8mm tall increment recorded in 2560meter elevated high land or injibara with mean value of 18.5°C and rain fall is 1300mm.
Influence of low stress handling during clinical visit on physiological and behavioural indicators in adult dogs: a preliminary study
Authors: Scalia Bruno , Alberghina Daniela , Panzera Michele
Published: January 2018

Low stress handling techniques or “Fear Free principles” in veterinary clinics are becoming an important research area aimed at improving small animal welfare, considering that the majority of dogs who undergo clinical examinations exhibit fear or anxiety signs. Objective of this study was to compare a number of physiological and behavioural indicators using low stress handling (LSH) and traditional (TT) techniques in order to assess whether the LSH approach had a positive impact on the dog’s welfare. Eight adult dogs were filmed while undergoing both LSH and TT visits (separated by a distance of seven weeks). The same usual sequence of events was followed for both visits (e. g. muzzle wearing, heart and lungs stethoscope examination, etc.) except that 1) during the LSH visit, the dog was free to explore the environment (while receiving treats) and play for five minutes before and after the visit 2) throughout the medical examination the veterinarians’ attitude and handling techniques were always aimed at preventing stress and guaranteeing the best physical support possible. The videos were then evaluated for the number of fear and stress signs the subjects showed. The examined physiological variables were respiration (breath/min), heart rate (HR) and rectal temperature (RT). Physiological variables were analysed by t-Test for paired data while frequency of behavioural fear indicators by Wilcoxon signed-rank test. Rectal temperature was within range in both groups but significantly higher (P<0.05) during LSH visit, while low head, lip licks and whale eye behaviours were significantly higher (P<0.05) during TT visit. These results suggest that low stress handling decreases frequency of some fear-related behaviours and could improve the quality of human-dog interactions. Future research that aims to replicate and further investigate these results in a large canine population is required.

Authors: Bauer Amy E. , Jordan Mary , Colon Monica , Shreyer Traci , Croney Candace C.
Published: January 2018

Field assessments of the health and welfare of kenneled dogs (Canis lupus familiaris) must be both accurate and rapid. In order to facilitate such evaluations, especially by individuals with limited training in canine behavior and welfare, a non-invasive tool was developed and pilot-tested utilizing dogs housed in commercial breeding facilities. Behavioral responses to approach were organized into three categories: red, indicating a fearful response to approach, green, indicating an affiliative or neutral response to approach, and yellow, indicating an ambivalent response to approach. The inter-rater reliability (IRR) of the tool when used by both behavioral experts and novice raters was evaluated with and without the presence of the dog’s familiar caretaker. Utilizing Cohen’s kappa, the experts had almost perfect levels of agreement (kappa=0.87). The novice raters had substantial levels of agreement (kappa=0.74). Overall, the dogs assessed by the novice raters had high proportions of green responses to approach and there was no statistically significant effect of caretaker presence on the proportion of green responses to approach. The assessment tool evaluated herein appears to have a high degree of IRR whether used by experts in canine behavior or by novice raters and may be a useful screening tool to determine the need for more in-depth welfare assessments.

Published: January 2018

Los estudiantes de veterinaria comúnmente tienen un concepto de la investigación científica basado en prejuicios. El presente trabajo describe una actividad enfocada a fomentar el espíritu investigador en el alumnado de veterinaria y enseñar a los participantes el modus operandi que rige la publicación y difusión de cualquier trabajo científico. Para ello se crearon grupos de alumnos que desarrollaron un trabajo experimental relacionado con la patología clínica y diagnóstico laboratorial, siguiendo metodología científica válida. Tras ello, cada grupo preparó un manuscrito en inglés y un póster de sus resultados. El manuscrito se sometió a una revisión por pares anónima por parte de los propios alumnos y se publicó en formato journal, mientras que el póster se presentó en inglés en un congreso de estudiantes. La metodología descrita se ha demostrado suficientemente eficaz a la hora de establecer un espíritu crítico en la evaluación científica de los estudiantes participantes, fomentando al mismo tiempo su capacidad de innovación y emprendimiento.

Spatial Distribution of Heavy Metals around the Gold Mine Ore Tailings of Hatti, Karnataka State, India
Authors: Ramappa Harish Etigemane , Muniswamy David
Published: January 2018

Mining is an imperative segment of the world economy as it contributes socio-economic status of the nations. However, developing countries like India due to lack of high profile industrial techniques and equipment, eluting effluents from the industrial process may contain various hazardous substances which greatly affect the environmental and human health. The present work is aimed with the distribution of heavy metals in and around Hatti Gold Mine Ore Tailing (H-GOT). The results elicit the mine ore tailings are having high-level contaminants of heavy metal than the crop lands of Hatti (Hs), Kotha (Ks), Chikka Nagur (Cs), Tawag (Ts), Lingsugur (Ls) of Raichur District, Karnataka. It was reported that, Hatti Gold Mine ore tailings hold about 41.31±0.49 mg/kg, 2.1±0.31mg/kg, 71.96±3.26 mg/kg, 39.56±1.47 mg/kg and 73.4±2.19 mg/kg of Arsenic (As), Cadmium (Cd), Copper (Cu), Lead (Pb) and Zinc (Zn) heavy metals respectively. While the crop lands metal contamination range depends on seasonal variation. In south-west monsoon farming lands metal contamination order is Hs> Ks>Cs> Ts >Ls, and it was decreased during Post-monsoon. This is the hallmark of the fetching huge amount of toxic heavy metals from mining center to nearest crop lands. The continuous squeezing of these toxic metals could trigger the bio-magnification in both aquatic and terrestrial ecosystem and it may impact various metabolic disorders.
On the Convergence of System-AMG in Reservoir Simulation
Authors: Gries Sebastian
Published: January 2018

System-algebraic multigrid (AMG) provides a flexible framework for linear systems in simulation applications that involve various types of physical unknowns. Reservoir-simulation applications, with their driving elliptic pressure unknown, are principally well-suited to exploit System-AMG as a robust and efficient solver method.

However, the coarse grid correction must be physically meaningful to speed up the overall convergence. It has been common practice in constrained-pressure-residual (CPR) -type applications to use an approximate pressure/saturation decoupling to fulfill this requirement. Unfortunately, this can have significant effects on the AMG applicability and, thus, is not performed by the dynamic row-sum (DRS) method.

This work shows that the pressure/saturation decoupling is not necessary for ensuring an efficient interplay between the coarse grid correction process and the fine-level problem, demonstrating that a comparable influence of the pressure on the different involved partial-differential equations (PDEs) is much more crucial.

As an extreme case with respect to the outlined requirement, linear systems from compositional simulations under the volume-balance formulation will be discussed. In these systems, the pressure typically is associated with a volume balance rather than a diffusion process. It will be shown how System-AMG can still be used in such cases.
Field Deployment of a Rigless Cable-Deployed Electric Submersible Pump Using a Vertical Wellhead

Published: January 2018

Electric submersible pumps (ESPs) are a widely used artificial-lift technology. Conventional ESP systems provide power with a cable banded to the outside of the tubing. These systems have drawbacks in terms of installation speed and efficiency. To overcome these obstacles, a novel cable-deployed (CD) ESP system developed for use in a production environment with high hydrogen sulfide (H2S) content is presented as a future solution. This paper focuses on the challenges, results, and lessons learned from the first field deployment in the world of a rigless high-H2S CD-ESP system.

A metal-jacketed power cable was a key enabler to the CD-ESP system. The metal-jacketed power cable delivers the best protection for an H2S attack and provides a smooth outside diameter that could be gripped on and sealed. The cable had been tested to withstand H2S levels up to 15% in the vapor phase and chloride levels in excess of 150,000 ppm, with an expected service life in excess of 10 years, derived from laboratory testing.

To overcome well-control concerns, a vertical cable-hanger spool (VCHS) was developed to enable the ESP cable to be terminated below the master valve. In addition to the surface termination of the cable, the VCHS provided hang-off and production-flow-through capabilities.

The CD-ESP system, using a specialized inverted ESP, required close integration between several equipment and service providers during the development of equipment and procedures to ensure success in the installation of the system. The system's initial deployment was in a benign onshore well that offered ample workspace for the various service providers to learn the unique aspects of this rigless deployment. The interface between the service providers at the surface-cable termination was critical to the successful installation. For this trial test, the well completion was changed from 4½-in. tubing to 7-in. tubing to accommodate the CD 562 Series ESP.

Lessons learned from this field trial will be incorporated into future trials of the technology. The goal of these future trials will be to deploy the technology in offshore H2S wells where high rig costs can be significantly reduced by using a lower-cost barge coupled with increased speed, efficiency, and ease of CD-ESP deployment.

Published: January 2018

Pears Pyrus communis L. collected from different sites of Kashmir Valley were found infected with Penicillium glaucum causing Penicillium rot. The diseased fruits appears light tan to dark brown. The decayed tissue becomes soft, watery and the lesion has a very sharp margin between diseased and healthy tissues. Decayed fruit has an earthy, musty odor. The pathogen was isolated and cultured on PDA medium for further fungal morphological observation and confirming its pathogenicity according to Koch’s postulates. Results of morphological data and pathogenicity test showed that the pears were infected by Penicillium glaucum Link resulting in Penicillium rot of pears. To our knowledge, it is the first report of pear fruit rot caused by P. glaucum in India. Study was also undertaken for the management of Penicillium rot of pear with some fungicides. It was revealed from the study that different concentration of fungicides brought about significant reduction in the mycelial growth and spore germination of Penicillium glaucum under in vitro conditions. Amongst the tested fungicides, carbendazim proved highly effective in inhibiting the mycelial growth and spore germination of Penicillium glaucum followed by hexaconozole, bitertanol and myclobutanil respectively. Higher concentration proved effective than lower concentrations.

This study investigates the performance of artificial intelligence techniques including artificial neural network (ANN), group method of data handling (GMDH) and support vector machine (SVM) for predicting water quality components of Tireh River located in the southwest of Iran. To develop the ANN and SVM, different types of transfer and kernel functions were tested, respectively. Reviewing the results of ANN and SVM indicated that both models have suitable performance for predicting water quality components. During the process of development of ANN and SVM, it was found that tansig and RBF as transfer and kernel functions have the best performance among the tested functions. Comparison of outcomes of GMDH model with other applied models shows that although this model has acceptable performance for predicting the components of water quality, its accuracy is slightly less than ANN and SVM. The evaluation of the accuracy of the applied models according to the error indexes declared that SVM was the most accurate model. Examining the results of the models showed that all of them had some over-estimation properties. By evaluating the results of the models based on the DDR index, it was found that the lowest DDR value was related to the performance of the SVM model.

Methane production from the algal biomass cultivated in a laboratory scale continuous photobioreactor (PBR) using sewage was evaluated in the present work. During the preliminary experiments, algal biomass reached up to 1.69 ± 0.35 g L–1 in 12 days' growth period. Besides, 65 to 100% removal in concentrations of total dissolved phosphorus (TDP), nitrate nitrogen (NO3–N), total ammoniacal nitrogen (TAN) and soluble chemical oxygen demand (sCOD) was also recorded. The sCOD removal in the reactor was 100%, whereas removal of TDP, NO3–N and TAN were up to 75, 40 and 92%, respectively. Upon anaerobic digestion, the fresh algal biomass showed methane yield of 180 mL g–1 VSfed. Further, algal biomass was stored under natural conditions in open containers (aerobic conditions) in darkness at room temperature (27–30 °C) for 72 h. Interestingly, >48% COD solubilization from algal biomass was observed during storage. Pretreatment through natural storage was further confirmed with qualitative observations including scanning electron and fluorescence microscopic analysis. Moreover, higher methane yield (284.38 mL g–1 VSfed) was observed from the samples stored for 60 h. Thus, natural storage for a designated period may be recommended as a prerequisite stage in the process of methane production from wastewater-grown algal biomass.

Wastewater treatment facilities are continually challenged to meet both environmental regulations and reduce running costs (particularly energy and staffing costs). Improving the efficiency of operational monitoring at wastewater treatment plants (WWTPs) requires the development and implementation of appropriate performance metrics; particularly those that are easily measured, strongly correlate to WWTP performance, and can be easily automated, with a minimal amount of maintenance or intervention by human operators. Turbidity is the measure of the relative clarity of a fluid. It is an expression of the optical property that causes light to be scattered and absorbed by fine particles in suspension (rather than transmitted with no change in direction or flux level through a fluid sample). In wastewater treatment, turbidity is often used as an indicator of effluent quality, rather than an absolute performance metric, although correlations have been found between turbidity and suspended solids. Existing laboratory-based methods to measure turbidity for WWTPs, while relatively simple, require human intervention and are labour intensive. Automated systems for on-site measuring of wastewater effluent turbidity are not commonly used, while those present are largely based on submerged sensors that require regular cleaning and calibration due to fouling from particulate matter in fluids. This paper presents a novel, automated system for estimating fluid turbidity. Effluent samples are imaged such that the light absorption characteristic is highlighted as a function of fluid depth, and computer vision processing techniques are used to quantify this characteristic. Results from the proposed system were compared with results from established laboratory-based methods and were found to be comparable. Tests were conducted using both synthetic dairy wastewater and effluent from multiple WWTPs, both municipal and industrial. This system has an advantage over current methods as it provides a multipoint analysis that can be easily repeated for large volumes of wastewater effluent. Although the system was specifically designed and tested for wastewater treatment applications, it could have applications such as in drinking water treatment, and in other areas where fluid turbidity is an important measurement.
The fluid flow through the related element system of technical device such as pipe–hydraulic resistance–pipe

Published: January 2018

In this paper the stationary flow through the pipe–hydraulic resistance–pipe element system have been investigated to determine how the liquid flow rate depends on the differential pressure applied to the system and the system geometry. The Navier–Stokes equations are solved numerically in axially symmetric geometry by the finite element method at irregular computational grid. It was found that the area of the non-linear pressure drop in the element system is localized at length of three inlet radii which allowed to build a model of arbitrary length of the system with a fixed length of hydraulic resistance. The pipe equivalent for the element system with hydraulic resistance have been constructed. A method for constructing a computer model for the element system, which later will enable to make calculations of whole technical device work in real time, have been proposed. This study is particularly relevant for the hydraulic elements of microelectromechanical systems, since it allows to optimize the geometry of the element system to obtain the necessary operating parameters of the technical device.

Fluid recovery from a well in the modes of constant pressure drop and constant flow rate is considered basing on a theoretical model of filtration in a hydraulic fracture. Exact analytical solutions are obtained that allowed analyzing the effect of the reservoir and fracture properties (such as porosity, permeability and crack width) as well as the rheological properties of the saturating fluid upon: pressure evolution in the fracture, well flow rate at constant pressure drop, and pressure evolution in the wellbore.

On the basis of theoretical models describing the filtration for a crack in an oil or gas reservoirs, the considered problem on the selection of fluids from the well in modes constant differential pressure and constant flow. For the considered tasks are received exact analytical solutions, based on which we analyzed the influence of reservoir characteristics of the formation and fractures (for example, their porosity, permeability and width of cracks) and the rheological properties of the saturating fluid on the evolution of the pressure in the fracture, the production rate at a constant differential to the dynamics of the pressure in the well.

In work results of a numerical research of influence of viscosity-temperature relation on structure of a convective Couette flow of thermoviscous liquid are presented in ring area between two coaxial cylinders under a condition when one of them has more high temperature.

Comparison of a convective Couette flow of model liquid with non-monotone temperature dependence of viscosity and liquid with constant viscosity is carried out. Depending on parameters of viscosity anomaly the steady and oscillation flow regimes both with periodic and with not repeating fluctuations of vortex structures are found. The number of time-constant vortex structures also depends on parameters of viscosity anomaly.
