Authors: Xie Chi , Zhou Yingying , Wang Gangjin , Yan Xinguo 
Published: September 2017

Abstract
In this paper, we investigate the disparities of China’s insurance market from the viewpoint of geography and enterprise by using the monthly data from January 2006 to December 2015. We divide the whole insurance market into two parts, namely property insurance and personal insurance. By constructing and analyzing minimum spanning trees of insurance market, we obtain the results as follows: (i) The connections between provinces are much closer than those of firms, and there are regional links between neighboring provinces in the minimum spanning tree (MST); and (ii) the domestic funded firms and foreign funded firms form two explicit clusters in the MSTs of property and personal insurance market.
Effect of Water Salinity and Water–Filled Pore Volume on High–Frequency Dielectric Measurements in Porous Media
Authors: Chen Huangye , Heidari Zoya 
Published: September 2017

Summary
High-frequency dielectric measurements have been attractive candidates for assessment of water-filled porosity in porous media. In the presence of saline water, the water molecules lose their orientation freedom partially because of hydration with ions and make these measurements sensitive to water salinity, which makes the interpretation of the dielectric-permittivity measurements challenging. The effects of water salinity on the real and the imaginary parts of dielectric permittivity have not yet been quantitatively studied in high-frequency (e.g., greater than 1 GHz) measurements. We measured dielectric permittivity of brine at frequencies ranging from 1 MHz to 3 GHz at room temperature and pressure conditions, where water salinity varies between 0 and 160 kiloparts per million (kppm). We also measured the dielectric permittivity of rock samples with different brine saturations. Our experimental results confirmed that there exists a critical frequency above which water salinity does not affect the real part of the dielectric constant, and such critical frequency increases as water-filled porosity and water salinity increase. At high frequencies where the real part of the dielectric constant is independent of the frequency, there exists a critical water-filled porosity below which water salinity has negligible effect on the real part of the dielectric constant. However, when water-filled porosity is higher than this critical value, the real part of the dielectric constant slightly decreases by increasing water salinity. Further, the results showed that at frequencies greater than the critical frequency, there is a critical water salinity below which the imaginary part of the dielectric constant increases as the water salinity increases, whereas the imaginary part of the dielectric constant decreases if the water salinity exceeds the critical value. The quantitative results on the effect of water salinity on dielectric measurements can potentially improve interpretation of dielectric-permittivity measurements for reliable assessment of water-filled porosity and hydrocarbon saturation.

Published: September 2017

El maíz (Zea mays L.) es uno de los cereales con mayor superficie sembrada a nivel mundial, debido a su importancia en la alimentación humana y animal. Son muchos los agentes etiológicos que ocasionan enfermedades en la plantas de maíz; sin embargo, Fusarium verticillioides (Sacc.) Nirenberg, es uno de los mohos a los cuales se le ha prestado especial atención por su amplia distribución, especialmente en zonas tropicales y subtropicales, su capacidad toxigénica y su resistencia. Por tal motivo, se evaluó la incidencia de F. verticillioides y el contenido de fumonisinas en granos de maíz blanco de once híbridos destinados al consumo humano provenientes de los estados Guárico y Yaracuy, Venezuela. Método: La cuantificación de especies toxigénicas se realizó por siembra directa de granos enteros y desinfectados con NaClO al 3,27%, sobre el medio malta sal agar, expresando los resultados como porcentajes de granos colonizados por mohos totales y por especies potencialmente toxigénicas. El contenido de fumonisinas se cuantificó por el método inmunoquímico con columnas de inmunoafinidad para fumonisinas (B1+B2). Resultados: No se observaron diferencias estadísticas significativas para la incidencia de F. verticillioides y la concentración de fumonisinas en las muestras evaluadas en ambos estados. La micobiota asociada a los granos de maíz fueron Aspergillus flavus, Aspergillus Niger, A. ochraceus, A. terreus, Eurotium chevalieri, F. verticillioides, Penicillium spp. Alternaria sp., y Curvularia sp. La mayor incidencia promedio de mohos toxigénicos la obtuvieron A. flavus (24,3%), F. verticillioides (14,6%) y Penicillium sp. (4,4%) en Yaracuy; no obstante, en Guárico fueron F. verticillioides (16,7%) y Penicillium spp. (13,8%). La concentración promedio de fumonisinas en Yaracuy y Guárico fue de 1,8 y 8,4µg/g, respectivamente, superando el límite permitido para consumo humano (1 µg/g).Discusión: Con base en la baja incidencia de F. verticillioides y los bajos contenidos de fumonisinas detectados en los híbridos D1B-348 (proveniente de Guárico) y D1B-246 (proveniente de Yaracuy), se recomienda su uso en los respectivos estados, como medida de control del patógeno a nivel de campo y evitar la posible contaminación con fumonisinas.

Published: September 2017

Abstract
This work evaluated the performance of ionic liquids (ILs) in supported liquid membranes in the removal of total cyanide from wastewater. Membranes were characterized by scanning electron microscopy and contact angle measurements to study the membrane morphology and wetting ability. In particular, the effects of operational parameters such as membrane immersion time, feed-phase concentration, and pH on cyanide removal were investigated. ILs are organic salts that are entirely composed of organic cations and either organic or inorganic anions. Since their vapor pressure is negligible, they can be handled easily; this characteristic gives rise to their ‘green’ nature. In this study, a hydrophobic IL, 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim]PF6), was immobilized in the pores of a solid polymeric support made of polyvinylidene fluoride. The optimal conditions were as follows: 1 hour membrane immersion time, 312.24 mg/L feed-phase concentration, a feed-phase pH of 4, 3% NaOH solution, and 1 hour stirring time. The cyanide removal was 95.31%. The treatment of cyanide using supported ionic liquid membrane (SILM) technology is a method with potential applications in industry.

Published: September 2017

The National Library of Education is the largest federally funded library in the world devoted entirely to education. In March 1994, Congress created this new national library, bringing together the former U.S. Department of Education Research Library; the 1-800 user service; INet (ED/OERI's Internet site and services); and the Technology Resources Center. These units now operate in partnership with the ERIC to carry out reference and referral services; collection and technical services; resource sharing and cooperation, including Internet Services (INet); and marketing/public relations. NLE is planning a network of national education technology and related resources. The network will promote greater cooperation and resource sharing among education and library professionals, policymakers, the public and other providers and repositories of education information in America. It will also apply information science, computer and telecommunications technologies for the enhancement of education information dissemination.
LEARNING ACROSS GENERATIONS AND CULTURES
Authors: Segal Joan 
Published: September 2017

Interests in school library services and in library services to the disadvantaged ran through much of Anne Galler's professional work. This paper, a personal description of the author's work with the Sky City Community School Library (Acoma Pueblo, New Mexico), reflects these interests. Likewise, the fact that this work came about as part of an inter-generational and cross-cultural informal learning experience sponsored through an Elderhostel service project reflects Galler 's personal interest inlifelong learning, and learning in retirement. The program included intensive learning about the Acoma Pueblo, about the education of indigenous peoples, and about the culture of the Acoma Indians. The author concludes that the experience highlighted the value of life-long learning.

Published: September 2017

Objective: This study examines the factors that influence information system (IS) interoperability of e-Government focusing on IS Interoperability as the key concept to reach successful e-Government implementation in Jordan.
Methodology: Use of qualitative methods of inquiry has been made to explore study variables and their relationships. A variety of published literatures related to scope of the study has been reviewed along with analyzing the e-Government strategy in Jordan during period 2014-2016. The interoperability levels of e-Government IS have been discussed in this paper. Finally, significant barriers that affect IS interoperability have been identified along with the factors that can drive it successful implementation.
Findings: Technical, semantic, and organizational interoperability are main stages for successful e-Government IS interoperability. Information and Communication Technology (ICT) infrastructure, top management support, human resources, data and information, security and privacy, and business process have been found as the major obstacles. Whereas, high level interoperability goals, commitment of government bodies, and customer focus have been identified as main success factors that lead to e-Government IS interoperability. The study suggests that strategies and work process should be aligned, common standards and knowledge should be shared to move towards e-transformation in Jordan.
Implications: This study can be starting point for the real life practical solutions for successful implementation of e-Government conceptual frame work. Finding of the study can be used to generalize about the factors that lead to success of IS interoperability within government agencies in other developing countries. This study enriches existing literature in this context. On practical side, the study contributes by identifying IS interoperability success factors and barriers within government agencies. The proposed conceptual model is first stage in the process of understanding factors that influence e-Government IS interoperability. Further studies may be needed to empirically evaluate the proposed conceptual model.

Authors: Mukharovska Inna 
Published: September 2017

Background
The diagnostic cancer in incurable stages, the transition to palliative care because of disease progression are significant psychological challenge for the patient. Psychological help for cancer patients during palliative treatment are no less important than medical therapy.

Methods
The study conducted at the Kyiv City Clinical Cancer Center during the 2012 - 2013 years in two phases. In first phase provided psychological investigation psychological condition of incurable cancer patients and its dynamics during palliative therapy with followed qualitative analysis of the data – participated 436 patients. Second phase included determining factors of psychological maladjustment and evaluation intensity of mental distress – participated 63 palliative cancer patients. The SCL-90r used for assessment of psychic distress.

Results
The prominent psychopathological symptoms in incurable cancer patients were somatization, depression and nonspecific symptoms. Less pronounced signs of mental distress in descending order of severity were anxiety, hostility, paranoid ideation, interpersonal sensitivity, obsessive-compulsive, psychoticism and phobic anxiety. Factors of psychological distress in cancer patients during palliative care include high physical distress; the impossibility of total control on physical and psychological symptoms; chronic pain; progressive deterioration of physical well-being; need to use opioids for relief pain; need for help; existential nature of stress; individual psychological characteristics. In patients identified psychological phenomena related to the palliative phase of treatment: psychological induction "pendulum", externalizing of mental stress, decentralization.

Conclusion
Cancer patients in the palliative stage of treatment experiencing intensive psychological distress and clinically constitute a special group with specific psychological needs, which need to be consider in providing psychological care.
Evaluation of the evoked brain potentials of patients with asthenia and anxiety symptoms and the partial loss of sight
Authors: Abdryakhimova Tsira , Abdryakhimov Rostislav , Snegir Andriy , Kleban Katherine , Mukharovska Inna 
Published: September 2017

Background
Loss of sight, even partial, especially in adulthood, is accompanied by emotional, motivational and social consequences that directly affect the psychophysiological state of the individual himself, his communication in society and, often, the social status of the subject.

Methods
From the group of patients-volunteers (n=15) with a partial loss of sight of traumatic genesis two groups were formed for carrying out neurophysiological studies: with predominant asthenia and predominant anxiety. The controle group (CG) constisted from patients of the same age (n=20) without psychiatric comorbidity. A study of acoustic event-related potentials of the brain (ERP) was carried out in the oddball paradigm with the recording of the time and correctness of a simple sensorimotor reaction.

Results
Comparative analysis of the asthenia group with the comparison group revealed a sufficient number of indicators of the ERP, which have significant statistical differences. The correctness of the sensorimotor reaction in this group was 98.3 ± 2.44%, whereas in the CG - 92.5 ± 5.74% (U = 62.5, p <0.01). The values of the amplitude of the early positivity of P1 in the asthenia group were 4.25 ± 3.312 μV, and in the CG -4.15 ± 7.933 μV (U = 50, p <0.001). The early negativity in that group was -2.78 ± 2.377 μV, and in the CG it was 10.55 ± 7.466 μV (U = 75; p <0.05).

Conclusion
In the asthenia group this is the correctness of the sensorimotor reaction and the amplitude of the components: P1, N1, P2, N2. In the anxiety group, such indicators were: latency period P1, intervals P1N1 and N2P3, amplitude swing P1N1. A specific marker of the asthenia group, distinguishing it from the CG, was the more positive values of the amplitude of the components P1, N1, P2, N2. Taking into account the low-frequency nature of the modulation of the amplitudes of these components (circa 2 Hz), it can be assumed that nonspecific brainstem systems are involved in the process.

AbstractLi(Ni1/3Mn1/3Co1/3)O2as a cathode material for lithium ion batteries shows good thermal stability, high reversible capacity (290 mAh g−1), good rate capability and better results in terms of environmental friendliness. In this paper thin film cathodes in the material system Li–Ni–Mn–Co–O were deposited onto silicon and stainless steel substrates, by non-reactive r.f. magnetron sputtering from a ceramic Li1.18(Ni0.39Mn0.19Co0.35)O1.97target at various argon working gas pressures between 0.2 Pa and 20 Pa. A comprehensive study on the composition and microstructure was carried out. The results showed that the elemental composition varies depending on argon working gas pressure. The elemental composition was determined by inductively coupled plasma optical emission spectroscopy in combination with carrier gas hot extraction. The films showed different grain orientations depending argon working gas pressures. The degree of cation order in the lattice structure of the films deposited at 0.5 Pa and 7 Pa argon working gas pressure, was increased by annealing in an argon/oxygen atmosphere at different pressures for one hour. The microstructure of the films varies with annealing gas pressure and is characterized using X-ray diffraction and unpolarized micro-Raman spectroscopy at room temperature. Electrochemical characterization of as-deposited and annealed films was carried out by galvanostatic cycling in Li–Ni–Mn–Co–O half-cells against metallic lithium. Correlations between process parameters, constitution, microstructure and electrochemical behaviour are discussed in detail.
Circumgalactic Oxygen Absorption and Feedback
Authors: Mathews William G. , Prochaska J. Xavier 
Published: September 2017

Abstract
O vi absorption in quasar spectra caused by intervening circumgalactic atmospheres suggests a downturn in the atmospheric column density in sightlines passing beyond about 100 kpc from central star-forming galaxies. This turnover supports the hypothesis that the oxygen originates in the central galaxies. When converted into oxygen space density using an Abel integral inversion, the O vi columns require

M
⊙ of oxygen concentrated near 100 kpc. Circumgalactic gas within this radius cools in less than 1 Gyr and radiates

erg s−1 overall. The feedback power necessary to maintain such oxygen-rich atmospheres for many Gyr cannot be easily supplied by galactic supernovae. However, massive central black holes in star-forming galaxies may generate sufficient accretion power and intermittent shock waves at

to balance circumgalactic radiation losses in late-type

galaxies. The relative absence of O vi absorption observed in early-type, passive

galaxies may arise from enhanced AGN feedback from their more massive central black holes.

Published: September 2017

Introduction: Rapid genotypic and phenotypic methods for multi-drug-resistant-tuberculosis (MDR-TB) detection are now widely available. Zimbabwe adopted the use of GeneXpert-MTB/RIF, microscopic-observation-drug-susceptibility-assay (MODS) and Mycobacteria-Growth-Indicator-Tube (MGIT) drug-susceptibility-testing (DST). Data is limited on the ideal combination of use of these methods in resource limited settings.
Methodology: Between August 2014 to July 2015, 211 sputa from MDR-TB suspects were tested with GeneXpert-MTB/RIF, MODS, manual-MGIT and Lowenstein-Jensen (LJ)-DST to determine diagnostic accuracy and turnaround-time (TAT), with LJ-DST as the gold standard. A performance score ranking table for diagnostic accuracy, TAT, costs, facilities and expertise requirements, was used to determine the most favourable tool.
Results: GeneXpert-MTB/RIF sensitivity was 96% (95%CI:80-100) and specificity was 95% (95%CI:90-97). MODS sensitivity was 88% (95%CI:68-97) and specificity was 97% (95%CI:87-100). Manual MGIT-DST had slightly lower sensitivity of 80% (95%CI:59-93). Median time to detection of MDR-TB was <1 day (IQR:0-0) for Xpert, 14 days (IQR:11-31) for MODS, 21 days (IQR:7-22) for MGIT-DST and 28 days (IQR:25-28) for LJ-DST. Operational costs for MODS, MGIT-DST, and GeneXpert-MTB/RIF were $21.20, $27.52 and $39.76 respectively. From a summation of scores including facility and expertise requirements per diagnostic technique, GeneXpert-MTB/RIF was the most favourable tool, followed by MODS and MGIT-DST.
Conclusions: For best scale-up of MDR-TB diagnosis in Zimbabwe, GeneXpert-MTB/RIF can be used for rapid detection of TB in smear negative cases, RIF-susceptibility for early treatment initiation and probable MDR-TB. MODS can rapidly confirm probable MDR-TB detected by GeneXpert-MTB/RIF, manual-MGIT can provide early results for susceptibility to other antibiotics, with affordable costs, with LJ-DST confirming discordant DSTs.
