Authors: wenying Chen 
Published: July 2019

Abstract
With the development of economic globalization and the proposal of the “One Belt, One Road” policy, cross-border e-commerce has ushered in development opportunities and developed rapidly. However, the lag of cross-border logistics service level and high logistics cost hinder the further development of cross-border e-commerce and become a bottleneck for the development of cross-border e-commerce enterprises. Therefore, in order to improve the cross-border e-commerce logistics level, cross-border e-commerce enterprises need to make reasonable choices about logistics mode to achieve the effect of reducing costs, improving service level and customer satisfaction. This paper divides the current cross-border logistics mode into express parcels and overseas warehousing and introduces them separately. It analyzes the macro influencing factors and micro influencing factors of the choice of logistics mode. By constructing the profit maximization function, it makes a selection of logistics modes and further studies the decision of self-operating or outsourcing in overseas warehouses. Finally, the corresponding suggestions are put forward according to the actual problems.

Published: July 2019

Abstract
The structural performance of steel frames with novel lightweight composite infilled wallboard is experimentally and numerically investigated under the curvature surface deformation. This study compares the mechanical behavior for the open-frame, the closed-frame with mudsill and the closed-frame with infilled wallboard, through experiment and finite element analysis, under the positive and negative curvature surface deformations respectively. The structural responses such as basement counterforce, additional strains at different key locations and the effects of mudsill and infilled wallboard are evaluated. It has been found that the steel frames with the new composite infilled wallboard can considerably increase the stiffness of the structures in resisting surface deformation and re-distribute the loads amongst the beam and column members in the frame. The force transmission effect of the mudsill accelerated the changes in the additional strain at column bottom. Frame beam is the main component that bears the curvature surface deformation. Mudsill has a consistent stress pattern with the frame beam and can significantly influence additional strain of the frame beam due to its stress sharing effect. The infilled wallboard is connected with the column-beam members and thereby influences the additional strain of the frame column significantly.

Abstract
In order to deeply study the influence of complex foundation pit group excavation on surrounding buildings, this paper takes concrete engineering as an example, using finite element software MIDAS GTS/NX to set up a three-dimensional deep foundation pit model for a piece of land project in a certain city, and carries out numerical simulation and analysis. This paper introduces the general situation of the project, the process of establishing the model, and the value of the deformation of the building and the supporting structure. The results show that the horizontal displacement of the same point increases gradually with the increase of the excavation depth of the foundation pit. The increase of excavation depth will also result in the maximum horizontal displacement moving gradually from the top of the slope to the middle and lower part of the deep foundation pit. In this paper, the three-dimensional numerical simulation analysis of the engineering is carried out according to the site construction procedure, in order to provide technical reference for the support selection and construction of similar projects.

Published: July 2019

Abstract
Affected by the continuous decline of the water level and the reform of the condenser, the actual operating conditions of a company’s circulating water pump seriously deviated from the design conditions. Especially in the double pump condition, only one pump can be maintained in normal operation, the other’s current is obviously low and the pump body vibrates greatly, and the double pump cannot be maintained in parallel operation. After several field tests and analysis, it was found that when the running head was between the two pump-inflection points of the parallel running, due to the difference in performance between the pump bodies, one of the circulating water pumps runs normally, while the other pump has a sudden current drop and an increase in pump vibration; at the same time, the two pumps have been running for more than ten years, the performance of the equipment is aging, and the head is insufficient, which is one of the main reasons.

Authors: Liu Denghua , Zhang Peng , Liu Xuetao 
Published: July 2019

Abstract
With the development of society, more non-renewable resources such as coal have been consumed, leading to energy shortage and environmental pollution. In winter, a large amount of coal is burnt for heating in the north, causing heavier smog nationwide, which is a great threat to people’s health. In recent years, some towns in the north also tried to provide heat for the buildings by burning natural gas to achieve boiler water circulation. However, that also caused environmental pollution to some extent. Research leads us to the invention of a solar heating system based on oil-water grading heat conduction and the design of pipelines and oil-water circulation in order to improve energy efficiency and improve heating quality in the north.

Authors: Sinulingga S , Munir E , Nurtjahja K 
Published: July 2019

Abstract
The rhizosphere has been known to contain rich microbial community which is directly influenced by secretions of roots. Rhizosphere microbes are known to have various benefits such as protection of plant from pathogens and toxic compounds, producing plant growth hormone, nitrogen fixation, and solubilizing phosphate. The objective of this study was to obtain rhizosphere bacteria capable of inhibiting the growth Fusarium oxysporum which is common pathogen attaching Capsicum annum. Bacteria were isolated from rhizosphere C. annum of local farm in Kabanjahe North Sumatra. Nine isolates based on morphological performance and biochemical analyses were obtained. Antagonistic test showed that two isolates BR6 and BR9 inhibited the growth of F. oxysporum with inhibition rate of 60% and 52%, respectively after 7 days incubation. These isolates also exhibited the activity to solubilize phosphate in Pikovskaya media with solubility index of 3.04 and 2.77, respectively. The other isolate BR5 even showed higher phosphate solubility index (3.42). These results suggest these isolates may have important role to support the growth of C. annum by providing protection from pathogens and phosphate ion. Then, study on the control of F. oxysporum attack on C. annum seedlings using these potential isolates is in process in our laboratory, as well as their molecular identification based on 16S rRNA.

Abstract
Tree species richness in disturbed and undisturbed site of Ketambe Research Station Ketambe, Southeast Aceh regency, Indonesia has been studied from March to May 2018. Research sites were determined using purpossive sampling method. Tree samples were recorded within a plot measuring 400 m2 for each sites with a total of 40 plots. Ecological parameters measured in this study were: Density (D), Relative density (RD), Frequency (F), Relative frequency (RF), Dominance (Do), Relative dominance (RDo), Importance Value Index (IVI), Shannon’s diversity index (H’), Margalefs index (R1), and Evenness (E). Estimation of biomass (B) carbon stock (CS) was conducted using allometric equation. Physico-chemical characteristics measured were: air temperature (°C), soil acidity (pH), light intensity (lx), air humidity (%), total organic N (%), and phosphate quantity (ppm) as secondary data. Our study found 79 tree species belonging to 30 families, 61 species in undisturbed site and 47 species in disturbed site. An important species with the highest Importance Value Index (IVI) was Dysoxylum sp.3 in undisturbed site and Macaranga tanarius in disturbed site. The biodiversity was more diverse in undisturbed site (H’ = 3.70; R1 = 10.93) than disturbed site on the whole study area (H’ = 3.47; R1 = 9.10). The values of evenness (E) varied between 0.66–0.68 among sites. Estimation of tree biomass and carbon stock followed the similar trend with a total of B = 971.299 Mg/ha and CS = 485.649 Mg/ha on the whole study area. The present study revealed that some vital tree species exist in forest area of Ketambe Research Station as carbon sinks along with their high biodiversities from both disturbed and undisturbed regions. The information on tree species diversity may provide a baseline information for conservation of the biodiversity in this area.
Constantinople and Moscow
Authors: Siecienski A. Edward 
Published: July 2019

Abstract
‘Constantinople and Moscow’ considers the Byzantines’ relationship with Rome during the thirteenth century and the continuing argument over the filioque and other Latin heresies. During the next century, it was an internal debate that rocked the Eastern church, as a dispute arose about whether one could in prayer have an experience of God as light. In 1453, Constantinople, the jewel of the Byzantine Empire, finally fell to the Ottomans and Orthodox Christians came under Islamic rule. The impact of the Reformation in Western Europe on Orthodoxy during the sixteenth century and the shift of the Orthodox world east to Moscow are also described.
“We no longer knew whether we were in heaven or on earth”
Authors: Siecienski A. Edward 
Published: July 2019

Abstract
‘“We no longer knew whether we were in heaven or on Earth”’ describes the experience of Orthodox church services. From the moment they enter the church for the Divine Liturgy, believers should feel themselves transported beyond time and space to the eternal worship of God that takes place in heaven, where the angels forever sing praises to the Holy Trinity. Orthodox Christians do not gather to “witness” the liturgy, but instead are there to make Christ present among them by their active participation in the church’s worship. The key liturgies of the Orthodox Church are described along with the feast of Pascha—the centerpiece of the Orthodox liturgical year—and the “The Twelve Great Feasts.”
Introduction
Authors: Siecienski A. Edward 
Published: July 2019

Abstract
Although it is the world’s second largest Christian denomination, with between 250 and 300 million adherents, Orthodoxy remains a little known and “mysterious” entity in the West. Yet for Orthodoxy, it is simply a way of being Christian ultimately rooted in the person of Jesus and the experience of the early church. The Introduction explains how Orthodoxy and Catholicism split between the eleventh and thirteenth centuries, and then developed along separate trajectories. Among the difficulties for modern Orthodoxy is the lack of any universal head, which prevents it from presenting itself to the world as a united entity. Despite this, Orthodox Christianity continues to thrive, both in its traditional homelands and in the West.
Heart-Thigh Cuff Pulse Wave Velocity: A Novel Nontechnical Measure of Arterial Stiffness
Authors: Fico Brandon G , Gourley Drew D , Wooten Savannah V , Tanaka Hirofumi 
Published: July 2019

Abstract

BACKGROUND
Recently, a novel index of arterial stiffness was developed to eliminate the placements of transducers on the carotid and femoral arteries and to make the measurement substantially easier. We evaluated the agreement of this new methodology with the well-established carotid–femoral pulse wave velocity (cfPWV).

METHODS
A total of 50 adults (28 men and 22 women) varying widely in age and blood pressure were studied. Heart-thigh pulse wave velocity (htPWV) and cfPWV were measured and compared.

RESULTS
Mean values of cfPWV and htPWV were 713 ± 145 and 699 ± 150 cm/s and were not significantly different (P = 0.43). Both cfPWV and htPWV were significantly associated with age (r = 0.80 and 0.58), body mass index (r = 0.44 and 0.31), and systolic blood pressure (r = 0.42 and 0.41). The 2 pulse wave velocity measures demonstrated a strong linear association with a Pearson correlation coefficient of 0.64 (P &lt; 0.001). This agreement was consistent with the results of the Bland–Altman plot.

CONCLUSION
The automatic htPWV method, which permits the data acquisition with minimum technical skill, time, and intrusion in an operator-independent fashion, has good potential as a screening device for assessing arterial stiffness in a clinical setting.

Abstract

Motivation
Biological systems function through dynamic interactions among genes and their products, regulatory circuits and metabolic networks. Our development of the Pathway Tools software was motivated by the need to construct biological knowledge resources that combine these many types of data, and that enable users to find and comprehend data of interest as quickly as possible through query and visualization tools. Further, we sought to support the development of metabolic flux models from pathway databases, and to use pathway information to leverage the interpretation of high-throughput data sets.

Results
In the past 4 years we have enhanced the already extensive Pathway Tools software in several respects. It can now support metabolic-model execution through the Web, it provides a more accurate gap filler for metabolic models; it supports development of models for organism communities distributed across a spatial grid; and model results may be visualized graphically. Pathway Tools supports several new omics-data analysis tools including the Omics Dashboard, multi-pathway diagrams called pathway collages, a pathway-covering algorithm for metabolomics data analysis and an algorithm for generating mechanistic explanations of multi-omics data. We have also improved the core pathway/genome databases management capabilities of the software, providing new multi-organism search tools for organism communities, improved graphics rendering, faster performance and re-designed gene and metabolite pages.

Availability
The software is free for academic use; a fee is required for commercial use. See http://pathwaytools.com.
