Published: July 2019

Abstract
Chinese government has put forward the strategy of developing nuclear power (NP), and now China has own the largest NP units that is under construction. The safety is foundation and premise of our country’s nuclear sustainable development, we must strengthen the national surveillance on nuclear safety. Since every nuclear power plants has their own probabilistic safety analysis (PSA) model, and the precursor analysis methodology is a PSA-based methodology, this method can help to analyse how important the events will affect the nuclear safety, and identify those events which have larger safety importance. Therefore, the precursor analysis methodology can act as a valid method to nuclear safety surveillance to improve the surveillance level and efficiency. In this paper, the introduction of this methodology is given, and a detailed case study about one incident and the application result at one NPP is given.

Abstract
The study of reservoir diagenesis is to reveal the type and characteristics of diagenesis. The general process of reservoir diagenesis research: Firstly, the study of diagenesis products, including systematic observation and analysis of reservoir cores, pays special attention to the changes of reservoir pores in time and space. We can obtain more accurate lithological data, various diagenetic phenomena and pore variation characteristics, and speculate on the diagenesis process that may be experienced. Secondly, according to the diagenetic parameters such as pore fluid temperature and pressure, the diagenesis reaction mechanism is discussed from the perspectives of physical chemistry and thermochemistry. Finally, combined with the stratigraphic, tectonic and sedimentary data of the basin, the reservoir diagenesis model is established to find out the evolution law of the pores.

Exogenous or Endogenous? An Integrated Spatial Perspective on Energy Corporates’ Environmental Performance: The Efficiency Mechanisms of Knowledge from Major Cities
Authors: Wang Teng 
Published: July 2019

Abstract
As one of the most concerned topics in environmental protection, the environmental performance of energy firms is extensively studied while little notices the influence of firms’ geo-location and major cities. To bridge this gap, we analyse the efficiency mechanism that links major cities and corporate environmental performance by integrating exogenous and endogenous spatial perspective. We find that through knowledge transfer and conversion, firms close to major cities centers could acquire more CEP knowledge from local stakeholders, and thereby improving environmental performance. The results are discussed along with managerial implications.

Authors: Munir E , Lutfia A , Yurnaliza  
Published: July 2019

Abstract
Endophytic microorganisms are microbial associates living in various part of host, yet expressing benefits to healthy plants. Existence of species-specific endophytes, endophytic fungi is still poorly studied especially in Zingiberaceae. In this study, we reported several endophytic fungal species isolated from rhizome of Elettaria through isolative efforts and molecular evidence. Host plant, Elettaria sp. was sampled from representative natural area, i.e. Hutan Sibayak which is known as biodiversity spot for Zingiberaceae in North Sumatera. Molecular identification revealed the identity of five isolated fungal strains collected from rhizomes of Elettaria, namely Trichoderma atroviride, Curvularia lunata, Schizophyllum commune, Trichoderma harzianum and Pholiota multicingulata. Phylogenetic tree is constructed based on Neighbor-joining method in a bootstrap test (1000x replication) with outgroup and database retrieved from NCBI GenBank. From our perspective, this is the first report on finding fungal endophytes from rhizomes of Elettaria sp. yet further investigation is needed to evaluate their future bioprospectives.

Abstract
This study has been conducted using the quadratic method to find out the species diversity index (H’). Five quadratic plots, with size of 10 m x 10 m (tree strata) were made for each area of samples. The percentage of open green space for each unit samples was measured by the calculation of ratio of the hospital area and the area of open green space for each sample unit. The result of the study was there were 51 species of trees which belongs to 28 families. The importance of each species in all stations was small or relatively homogeneous, but there were eight species of relatively high importance plants. The results of the diversity index analysis (H’) showed that the value of H’ ranged from 1.484 to 3.082, which placed two hospitals into high H’ values including Zainal Abidin Hospital (H’ = 3.082) and Kesdam Hospital (H’ = 3.015). The other stations had H’ medium and low values. Therefore, the OGS data analysis found that 10 out of 12 observation stations had the OGS value more than 50% or the OGS ratio of 11 hospitals in Banda Aceh was > 30% and fulfil the requirements of the law on OGS.

Published: July 2019

Abstract
The prevalence of Early Childhood Caries (ECC) in various countries is quite high, even at the age of 2 years the incidence is quite apprehensive. One simple and effective ECC alternative prevention is tooth brushing by using lysozyme toothpaste. Lysozyme can kill S.mutans bacteria by hydrolizing bacterial cell walls. This study aims to compare the salivary lysozyme concentration and the number of S.mutans colonies between pre-treatment and after 1 month tooth brushing by using 0.1% lysozyme toothpaste. This research is single masked clinical trial. The sample size of this study is 73 under 3 years old children, consisting of 31 caries-free children and 42 ECC children. The research subjects are obtained from Posyandu in Medan Selayang and Medan Johor District by using purposive sampling. Criteria for ECC is based on the American Association of Pediatric Dentistry (AAPD). Data analysis use Mann-Whitney and Wilcoxon tests because the data are not normally distributed, p < 0.05. The result shows that after tooth brushing by using lysozyme toothpaste, reduction of lysozyme concentration was detected on both groups of caries-free and ECC children compared to the state before tooth brushing, but it is not statistically significant (p > 0.05). Similiarly, reduction in number of S.mutans was detected after tooth brushing by using lysozyme toothpaste, although it is not statistically significant (p > 0.05). As conclusion, lysozyme toothpaste can reduce the growth of S.mutans bacteria, but is only inhibitory or bacteriostatic. Therefore, lysozyme toothpaste can be used as an alternative of caries prevention for early childhood.

Published: July 2019

Abstract
To investigate the origins, other than fossil fuel combustion and biomass burning, of urban carbonaceosus aerosols, we studied the fine (PM2.5) aerosols collected in Guiyang, Southwest China in winter (December 10–23) 2012 for organic carbon (OC), elemental carbon (EC) and water-soluble diacids, oxoacids, α-dicarbonyls and fatty acids as well as inorganic ions. Oxalic acid (C2) found to be the most abundant diacid species followed by succinic (C4) and terephthalic (t-Ph) acids, respectively. Even-carbon numbered fatty acids showed high abundances with a peak at C16. OC, EC and most of diacids and related compounds, but not inorganic ions, showed a similar temporal pattern with a drastic rise in December 15 day- and night-time samples during the campaign. Based on molecular distributions of diacids and fatty acids, and linear relations of OC and EC with selected marker ions and diacid species, we found that the organics and EC in PM2.5 are mainly derived from higher plant/cooking and municipal waste burning emissions in Guiyang. This study implies that municipal waste burning largely contributes to carbonaceous aerosols and warrants a need of further research on its role in aerosol loading and air quality in the urban atmosphere.
“I believe”
Authors: Siecienski A. Edward 
Published: July 2019

Abstract
The Nicene-Constantinopolitan Creed begins with the affirmation “I believe in one God.” There is also the belief that this one God is incorporeal, outside both time and space, and beyond our comprehension. Yet at the same time, this unknowable God has revealed himself to us in many ways. Orthodoxy, like other faiths, struggled to reconcile these two seemingly contradictory beliefs. ‘“I believe”’ explains that what makes Christianity distinct from the other Abrahamic faiths is the belief that the one God exists as a Trinity of persons—the Father, Son, and Holy Spirit. It also describes the concept of theosis (or deification) that is central to Orthodox thinking about the human person and his/her destiny.
“Pray unceasingly”
Authors: Siecienski A. Edward 
Published: July 2019

Abstract
Orthodox spirituality begins with the presupposition that humanity was created to be in communion with God and that this state is not just something achieved after death, but also something one can attain in this life. Although, Orthodoxy recognizes that this is not easy. ‘“Pray unceasingly”’ explains that the goal of the spiritual life is to move closer to God in communion and strive to do his will in all things. This occurs when the Christian comes to possess three virtues: love, self-mastery, and prayer. Prayer is at the very center of Orthodox life. Various spiritual works that have helped shape the Orthodox tradition, as well as the role of monasticism, are discussed.
“One, holy, catholic, and apostolic Church”
Authors: Siecienski A. Edward 
Published: July 2019

Abstract
Since its beginning, Christianity has affirmed that believing in Christ necessarily meant belonging to a community of believers. For the Orthodox, the church is the assembly gathered together by Christ himself in order to be his ongoing presence in the world. ‘One, holy, Catholic, and Apostolic church’ describes how the model of collective leadership and decision-taking shown by the apostles became the norm for the Orthodox and explains the importance in Orthodoxy of the synodal principle. It also outlines the structure of the Orthodox church—fifteen self-governing churches, each ruled by a patriarch or metropolitan bishop—and describes its relations with other Christian groups, including the Roman Catholic church.
Hitler myths
Authors: Caplan Jane 
Published: July 2019

Abstract
‘Hitler myths’ introduces the history of National Socialism through three myths or images encapsulating different dimensions of the power attached to Hitler and his regime: the claims that Hitler had survived long after 1945; the image of a monolithic, all-powerful totalitarian regime commanding mass obedience; and the power of Germans’ belief in ‘the Führer’ to reconcile them to Nazi dictatorship. Each offers a key to the history of Nazi Germany: the nature of power and leadership; the relationship between ideology, consent, and terror; and the climax of war and genocide.
