Authors: Humoodi akram , Aziz Baroz , Khidhir Dana
Published: June 2020

Throughout the production and reservoir lifecycle, the asphaltene precipitation is an ever existing problem through changing the porosity, permeability and wettability leading to decline in production. The conditions that govern Asphaltene precipitation varies from well to well and from reservoir conditions of high pressure and temperature to surface conditions and need to be studied case by case. The modeling and predicting the phase behavior and precipitation of Asphaltene is paramount for wells in Kurdistan region as it is developing its oil and gas industry. Crude oil samples from three wells in Kurdistan Region-Iraq were selected for this study. Experimental data such as crude oil composition using Gas Chromatography, PVT analysis and reservoir pressure and temperature were used as input data into Computer Modeling Group CMG simulator and a model of Asphaltene phase behavior was suggested. The model suggests that the maximum precipitation occurs near the bubble point pressure at reservoir conditions. This is validated and compared with results in literature indicating similar behavior of crude oil. To predict the Asphaltene precipitation at surface condition a modified Colloidal Instability Index CII were used and the results were validated by De Bore plot

Authors: Zhang Jin , Yin Xiuling , Li Zuxin , Sun Dufen , Liu Shenaoyi
Published: June 2020

This article analyzes reform and amendment of petroleum tax policy in Russia to investigate instability of tax regime which is one of the main concerns for decision making in asset acquisition. Historical and recent amendments of upstream fiscal terms in Russia are reviewed and studied in an attempt to understand the trends of reform. Tax burden of four different cases is modeled with the change of tax policy to analyze the effect of tax incentives. The recent “tax maneuver” of transferring export duty to Mineral Extraction Tax (MET) is studied in detail to analyze effects to upstream, refinery, and customers. Net present values of three field cases under previous tax regime and new Added Income Tax (AIT) regime are comparatively studied with cashflow modeling. The article concludes that recent “tax maneuver” has indirect influence on upstream sector but may lead to upward pressure on retail. New AIT regime introduces a universal taxation system and requires less government intervention, which may reduce aboveground risk of unstable fiscal regime and boost international investment in Russia. Also, key suggestions are summarized for international investors who are interested in oil and gas asset in Russia.
Structural Change and Growth Prospects in the Turkish Manufacturing Industry
Authors: TUNCER İsmail , MOALLA YAPRAK Maya
Published: June 2020

The growth and development literature emphasize two sources of labor productivity growth. First, productivity improvements triggered by physical and human capital accumulation and technological change and second, productivity improvements arising from movements of resources towards high productivity industries, that is structural change. The effect of structural change may be productivity enhancing or may bring a drag on aggregate productivity. Empirical studies highlight growth enhancing structural change for newly industrialized Asian countries while indicates weak or growth reducing structural change for some Latin American and African countries. Moreover, these studies also highlight the importance of movements of resources within the manufacturing sub industries. The process of structural change and economic development of developed countries is well documented but studies about less developed or developing countries is very weak. In this respect this study aims to examine whether the Turkish economy fits into this picture of growth-enhancing or reducing structural change? The conventional shift-share analysis is used in order to analyze the effect of structural change on the productivity of the manufacturing industry and the whole Turkish economy for the period of (2003-2017). The results suggest that on average, the within growth effect dominates labor productivity improvements whereas between growth and covariance effects account for very small parts of productivity growth for all the periods.
Is oral hygiene as important as hand hygiene during COVID-19 pandemic?
Authors: Bains Vivek Kumar , Bains Rhythm
Published: June 2020

Oral hygiene is an integral part of personal hygiene practices and should not be neglected. Similar to hand hygiene, oral hygiene is essential in reducing infection from the oral cavity, and thus, its transfer to the upper and lower respiratory tract. Although there is no randomized clinical trial, oral hygiene may imply to reduce the morbidity and mortality related to coronavirus disease pandemic potentially. At present, standard oral hygiene measures consist of thorough cleaning of all surfaces of teeth, interdental areas, and tongue daily. Oral health-care providers should emphasize its importance. Thorough toothbrushing for “Two Times For Two Minutes” in a day is an easy key to remember.
Orthodontic management of impacted maxillary canines
Authors: Bjerklin Krister
Published: June 2020

The prevalence of impacted maxillary canines is 2–3%. In Caucasian populations, it is reported to be more palatally displaced than buccally, with the opposite trend seen in Asian populations. At the ages of 9–11 years, the position of the canine germ should be diagnosed, for most children through clinical supervision. In 7–10% of children, the clinical investigation must be supplemented with radiographic investigation, in most cases with intraoral radiographs. About 50% of impacted canines cause root resorption of the adjacent teeth. To detect the severity of resorption, cone-beam computed tomography is necessary. Root resorptions on incisor roots occur most often at 11–12 years of age. Early diagnosis of ectopically positioned maxillary canines is very important. In cases with palatally displaced canines and no root resorptions, extraction of the primary canines has been found in different studies to give good results. If the permanent canine has not started to normalize its position within 12 months, orthodontic treatment must be taken in consideration. Often, this is done by surgical exposure and orthodontic traction of the canine out into the dental arch.
Virtual States and Symbolic Markets of Identity
Authors: Kirchanov Maksim V.
Published: June 2020

The author analyzes virtual states in the contexts of identity markets. There is assumed that virtual states can play the role of both subjects and objects of modern symbolic exchange. The article shows that virtual states do not have a common definition, and those who study them offer different approaches ranging from economic to cultural, from social to anthropological. On the one hand, virtual states can sell their identities. The author presumes that markets can be defined as cultures, and cultures as markets. On the other hand, the virtual states’ “products” that actualize their identity can also be goods. There is assumed that the processes of globalization and virtualization significantly changed the vectors and trajectories of identities development, turning them into a part of the market economy. The article assumes that the nation-state is gradually losing its monopoly right to represent the identity of the nation, and new actors are trying to challenge this right by proposing their own projects for identity development.

The author believes that the emergence of virtual states in identity markets was the result of a performative turn and a craft revolution, for virtual states appeared as the consequences of economy craftivization, offering various mechanisms to monetize identities and turn them into sacred and symbolic political products. The author believes that the virtual state was caused by the craftivization of the serial mass identities proposed in the 19th century as in the age of nationalism. There is assumed that the virtual states were the attempts to challenge the regular state’s monopoly inherited from the modern era to construct national identities. Therefore, the article analyzes the virtual states as attempts to revise the modern nation-state in the contexts of a cultural turn in the economy, which turned it into a sphere of production of meanings and identities. In general, the author considers virtual states as a new and alternative form of economic functioning, where the sense-making and meaning-generating constructs that invent and imagine new types and forms of identities become goods.
Gold Embroidery Style Features of the Mishar Tatars of the Ulyanovsk Region
Authors: Shklyaeva Lyudmila M.
Published: June 2020

The article reveals the origins and style features of the gold embroidery of the Mishar Tatars of the Ulyanovsk Region. Though surrounded by a population that is not uniform in ethnic composition, including the Chuvash, Mordovian, Mari, Udmurt and Russian peoples, the Mishars have preserved the aesthetic preferences of their ancestors. For centuries, the bib — an element of the national costume — has maintained the visually expressed originality of its decorative design conditioned by the traditions characteristic of this local group. The gold embroidery was a hereditary female occupation; its technique, as well as unique ornamental elements, were imparted from mother to daughter. Samples of needlework by masters of the past indicate the uniqueness of the patterned finish as well as the main trends of its development. The design techniques include large floral elements arranged in a certain compositional order. Its artistic structure uses the principle of symmetry as a reflection of the balance and stability of the universe. The repetition of images symbolizes the cyclical nature of being and reproduction processes. The style features of the Ulyanovsk Mishars’ gold embroidery include the homotypic impregnated technique and the relief of finishing elements. The interpretation of the key character-symbol in the center, which combines solar and floral forms, is diverse. The stylistic features of the Mishars’ gold embroidery reflect the system of the spiritual values common to the Tatars that were feeding the artistic forms of decorative art, originally sourced by the Bulgarian urban culture of the Golden Horde period, and then the Kazan Khanate. For many centuries, the best samples were selected and polished in the course of time. The style-forming elements of the national costume components’ gold decoration were steadily reproduced. The tradition of their application allows us to assume that the ancestors of the modern Mishar Tatars living in the rural part of the Ulyanovsk Region were of urban origin.

Published: June 2020

A mathematical model of the level of development of digital leadership in leading scientific and technological sectors has been proposed. The assessment is proposed to be carried out in five main areas, each of which includes both quantitative (for example, the share of modern (digital) training areas in the total number) and qualitative criteria (for example, the speed and effectiveness of interaction between the organization’s departments).Using the lower level of the hierarchy, the criteria of one direction are compared in pairs by the strength of their influence on the key direction as a whole. As a result, a matrix of pairwise comparisons is created. The level of development of digital leadership is characterized by an aggregated indicator calculated on the basis of the normalized matrix vector. The assessment methodology can be used both by organizations in the scientific and technical sectors (universities, institutes, research centers, etc.), and by government bodies responsible for the implementation of activities related to digitalization.

Authors: Kraft Marvin , Gronych Lara , Famprikis Theodosios , Ohno Saneyuki , Zeier Wolfgang
Published: June 2020

Sulfidic sodium ion conductors are currently investigated for the possible use in all-solid-state sodium ion batteries. The design of high performing electrolytes in terms of temperature-dependent ionic transport is based upon the fundamental understanding of structure – transport relationships within the given structural phase boundaries inherent to the investigated materials class. In this work, the Na+ superionic structural family of Na11Sn2PS12 is explored by using the systematic antimony substitution with phosphorous in Na11+xSn2+x(Sb1-yPy)1-xS12. A combination of Rietveld refinements against X-ray synchrotron diffraction data with electrochemical impedance spectroscopy is used to monitor the changes in the anionic framework, the Na+ substructure and the ionic transport. A new simplified descriptor for the average Na+ diffusion pathways, the average Na+ polyhedral volume is introduced, which is used to correlate the contraction of the overall lattice and the found activation barriers in the system. This study exemplifies how substitution affects diffusion pathways in ionic conductors and widens the knowledge about the related structural motifs and their influence on the ionic transport in this novel class of ionic conductors.
Experimental Evidence of Two-fold Electromagnetic Enhancement Mechanism of Surface-Enhanced Raman Scattering
Authors: Kumar Samir , Tokunaga Kouta , Namura Kyoko , Fukuoka Takao , Suzuki Motofumi
Published: June 2020

The surface-enhanced Raman scattering (SERS) electromagnetic (EM) enhancement mechanism is a two-fold enhancement process in which both the incident and scattered Raman fields are enhanced. In this letter, we present new direct evidence of the two-fold EM mechanism by using an Ag nanorod array/SiO2 dielectric layer/Ag mirror multilayer thin film "local plasmon resonator". The two-fold EM enhancement mechanism of SERS was confirmed by analyzing the optical absorption and Raman scattering spectra of the local plasmon resonator for excitation and scattered light. The effect of light interference was altered by varying the film thickness of the SiO2 phase control layer (PCL), and the absorbance in the Raman scattering wavelength range was reduced from 90% to 0%. We also demonstrated that the intensity of the background emission is closely related to the enhancement of the scattered field and provides substantial evidence for a two-fold SERS enhancement mechanism.

This study aimed to provide data to determine the prevalent virulence factors (vacA and cagA genes) in Jeddah city, western Saudi Arabia, by sequence analysis. This study included 60 patients with symptoms similar to H. pylori infection. H. pylori were identified by using the 16s rRNA sequence. Then, the screening for specific genes in H. pylori (vacA and cagA) was done by using automated DNA sequencing analysis, and the DNA sequences were compared by BLAST and sequence alignment of the vacA nucleotides that are present in all H. pylori strains using those already reported in GeneBank from various studies. Results indicated that H. pylori infection was detected in 13.3%, while 86.7% were negative samples in our study patients. Interestingly, the vacA gene was found in 8.3%, while the cagA gene was not appear in patient. Also, the female prevalence rate was higher than males (11.7% female versus 1.7% males), and the highest infection was between age 40-49 by 6.7%. In conclusion, this study revealed that the vacA gene was spread in the patients infected with H. pylori in Jeddah, while the cagA gene was not appear in any isolate.

Wireless sensor networks (WSNs) have experienced enormous growth, both in terms of the technology used and their practical applications. In order to understand the features of WSNs that make the solution suitable for a speciﬁc purpose, one needs to be aware of the theoretical concepts behind and technological aspects of WSNs. In this paper, the signiﬁcance of WSNs is illustrated, with a particular emphasis placed on their demands and on understanding researchrelated problems. A review of the literature available is presented as well. Detailed discussions concerning sensor node architecture, diﬀerent types of sensors used and their relevance for various types of WSNs is presented, highlighting the need to achieve application-speciﬁc requirements without degrading service quality. Multipath and cluster-based routing protocols are compared in order to analyze QoS requirements they are capable of satisfying, and their suitability for diﬀerent application areas is reviewed. This survey highlights the performance of diﬀerent routing protocols, therefore providing guidelines enabling each of the routing techniques to be used, in an eﬃcient manner, with factors such as speciﬁc network structure, protocol operation and routing path construction taken into consideration in order to achieve better performance.

In this paper we consider a link, characterized by speciﬁc capacity, that services multi-rate random or quasirandom traﬃc. Random traﬃc is generated by an inﬁnite number of traﬃc sources, while quasi-random traﬃc is generated by a ﬁnite population of traﬃc sources. The link is modeled as a multi-rate loss system. Handover and new calls are distinguished. New calls compete for the available bandwidth under a threshold call admission policy. In that policy, a new call of a particular service-class is not allowed to enter the system if the in-service handover and new calls of the same service-class plus the new call, exceed a predeﬁned threshold (which can be diﬀerent for each service-class). On the other hand, handover calls compete for the available bandwidth based on the complete sharing policy. We show that the steady state probabilities in the proposed models have a product form solution (PFS). The PFS leads to a convolution algorithm for accurate calculation of congestion probabilities and link utilization.

Authors: Kiedrowski Piotr
Published: June 2020

The article describes a project concerned with deploying PLC technology in railway light signals. The proposal increases reliability of communication between railway light signals and the railway automation center, relying on frame retransmissions instead of the FEC technique. The paper presents the results of long-term FER measurements performed in a narrowband PLC-based communication system. The said results are used as communication reliability metrics. Deployment of dual channels in order to increase communication reliability is discussed as well, as is eﬃciency of FEC-based convolutional coding. The results are veriﬁed in a real world environment.

Published: June 2020

In this paper, a wireless three-hop relay communication system operating in a Rayleigh multipath fading environment is analyzed. The output signal from such a system is a product of signal envelopes from all sections, meaning that it is actually a product of three random variables (RVs) with Rayleigh distribution. We considered here the ﬁrst-order characteristics: probability density function (PDF), cumulative distribution function and outage probability (OP). Then, the moments and amount of fading (AoF) were derived in the closed forms. The second order characteristics we present include the following: level crossing rate (LCR) and average fade duration (AFD). A few graphs are given to show the impact of the speciﬁc parameters of the wireless three-hop relay system.

Published: June 2020

The Internet of Things is changing the approach to data transmission, protocol design and network services. The challenge faced by designers of IoT solutions is to determine the scalability of a given technology, with a particular emphasis placed on unlicensed frequency bandwidth (ISM) transmission in highly urbanized areas. Because the design and implementation of a wireless network for the Internet of Things, relying on each of the presented technologies, is expensive and time consuming, it must be preceded by a performance assessment based on computer simulations. The literature contains various approaches to modeling the mechanisms of the MAC layer of LoRa technology and to its implementation in LoRaWAN networks. The article provides an overview of major LoRa MAC network simulators. It presents and comments on the most important research results obtained by the authors of the aforementioned software

Introduction: Congenital syphilis is a serious public health problem, it is responsible for several unfavorable outcomes such as fetal or perinatal death. In this sense, in order to provide information for better planning of education and prevention measures in vulnerable groups aiming at reducing the transmission chain, the objective of this study was to analyze epidemiological aspects of congenital syphilis in Tocantins state. Outline: Cross-sectional, retrospective study with a quantitative and descriptive approach by consulting the database of the Information System for Notifiable Diseases of Brazilian Ministry of Health from January 2009 to December 2019. Results: 1746 reports of syphilis were verified in the age group under one year of age. Regarding the mother's age group, a greater number of cases were identified between 20 and 29 years old, totaling 959 diagnosed cases. Considering the time of diagnosis, most were performed during prenatal care (945 cases), those mothers with less education had a higher incidence. Implications: The profile of congenital syphilis in Tocantins state has a high incidence of cases in the sample studied, a fact associated with deficits in the therapeutic interventions of infected pregnant women.
