Impact of corrosion product removal to depth of corrosion damage in weldment joint
Authors: Hodač J. , Fulín Z.
Published: January 2020

Corrosion flaws in pipelines can caused severe financial losses and also can be dangerous for people. One of the most frequently damaged parts are dissimilar pipe welds. We would like to understand how corrosion process reacts on corrosion product removal. Outputs from experiment will be used for production of test specimens. For testing we chose standard dissimilar weldment used in Czech power plants. It is joint with 08Ch18N10T and 22K (GOST) steel. Joint is cut to 24 same specimens. There are exposed to flowing water solution of 5% NaCl. Half of the specimens are regularly mechanically cleaned. The joint is metallographically observed and parts with and without corrosion products are compared. Water salt solution increased pH from 7,25 to 7,86 during 31 days test and conductivity varies around 74 mS cm−1. Metallographic observation indicates that corrosion under corrosion products layer is locally speed up and causes pitting corrosion. Cleaned specimens indicate plane corrosion with lower depth. These results indicate that slag in pipeline could locally speed up corrosion depth penetration. On the other hand, solutions with abrasive particles (which can wipe out the corrosion product) will probably facilitate plane corrosion damage on pipeline walls. This test brings us another knowledge, how to simulate realistic corrosion damage for production of NDT qualification test pieces.

Published: January 2020

For achieving a long service life of stamping dies for new types of steel sheets intended for the automotive industry, the tribosystem must be optimally designed. One of the possible solutions is its optimization by coatings. More modern coating technologies for stamping dies include PVD (physical vapor deposition) and CVD (chemical vapor deposition) methods. The properties of PVD TiCN and DLC (diamond-like carbon) coatings deposited on ledeburitic high-alloy Cr–Mo–V steel were analyzed by standard tests (coating adhesion by both the scratch and Rockwell C tests, microhardness by Vickers method and coating thickness by Calotest) and developed tribo-meter of the “friction jaw-roller” type at drawing double-sided hot-dip galvanized steel sheet. The obtained results showed better tribological behavior of the DLC coating.

Effect of Torso Non-Homogeneities in the quasi-static inverse problems arising in electrocardiology
Authors: Ainseba BedrEddine , Bendahmane Mostafa , Lopez Alejandro
Published: January 2020

In the present paper, an homogeneous and non-homogeneous inverse problem constrained by the stationary problem in electrocardiology representing the heart, lungs surfaces, and torso model is investigated. Our goal is to reconstruct the electrical potentials on the surface of the heart from the information obtained non invasively on the torso surface. The existence and uniqueness of solution for the heart-torso problem and the related inverse problem is assessed, and the primal and dual problems are discretized using a finite element method. We present some preliminary numerical experiments using an efficient implementation of the proposed scheme in homogeneous and non-homogeneous cases. Finally, we demonstrate the effect of the non-homogeneity on the reconstructed epicardial potential and show that the inverse ECG problem cannot be solved by the classical BEM (boundary element method).

Authors: Nziku Faustine , Kumar Santosh
Published: January 2020

In this paper, we present fixed point results for Boyd and Wong type [3] generalized contractive condition in partial metric spaces. In particular, we generalize the fixed point results due to Akkouchi [1] in complete partial metric spaces in which the continuity requirement for a mapping is relaxed to obtain the results. In addition to that we present a common fixed point theorem for a pair of maps. An illustrative example is also constructed to exhibit the results.
Aspects of the Theory on ‘Ideas’, ‘Eide’ and ‘Logoi’ of Beings in George Pachymeres
Authors: Petridou Lydia
Published: January 2020

In this study, we are discussing the terms ‘idea’, ‘eidos’, and ‘logos’ in George Pachymeres’ Paraphrase of Dionysius the Areopagite’s De divinis nominibus. This is a very important topic, at least from the ontological point of view. Many questions come to the fore, such as whether the three terms are as to their meaning the same, whether their non-autonomous character is mentioned, what their relation with the divine energies is and whether and how they are connected to the divine will. The structure of our study is based on the fact that the terms come from the Platonic, Aristotelian, and Patristic tradition respectively. Considering that both God and the created beings are objective realities, which the human consciousness is asked to investigate, we attempt to extrapolate ontology to the gnoseological level as well. I.e. we attempt to explain the matter of ‘universals’ relying on two questions. Specifically, from the ontological point of view: do they exist independently? And, from the gnoseological point of view: what is their relation to the human thinking?
’That Ancient and Christian Liberty’: Early Church Councils in Reformation Anglican Thought
Authors: Gazal Andre A.
Published: January 2020

This article will examine the role the first four ecumenical councils played in the controversial enterprises of John Jewel (1522-71) as well as two later early modern English theologians, Richard Hooker (1553-1600) and George Carleton (1559-1628). In three different polemical contexts, each divine portrays the councils as representing definitive catholic consensus not only for doctrine, but also ecclesiastical order and governance. For all three of these theologians, the manner in which the first four ecumenical councils were summoned and conducted, as well as their enactments touching the Church’s life provided patristic norms for its rightful administration. Jewel, Hooker, and Carleton each argued that the English Protestant national Church as defined by the Elizabethan Settlement exemplified a faithful recovery of patristic conciliar ecclesiastical government as an essential component in England’s overall endeavor to return to the true Church Catholic. Jewel employed these councils in order to impeach the Council of Trent’s (1545-63) status as a general council, and to justify the transfer of the authority of general councils to national and regional synods under the direction of godly princes. Hooker proposes the recovery of general councils as a means of achieving Catholic consensus within a Christendom divided along national and confessional lines while at the same time employing the pronouncements of the first four general councils to uphold the authoritative patristic and catholic warrant for institutions and practices retained by the Elizabethan Church. Finally, amid the controversy surrounding the Oath of Allegiance during the reign of James VI/1 (r. 1603-25), George Carleton devoted his extensive examination of these councils to refute papal claims to coercive authority with which to depose monarchs as an extension of excommunication. In so doing, Carleton relocates this ‘coactive jurisdiction’ in the ecclesiastical authority divinely invested in the monarch, making the ruler the source of conciliar authority, and arguably of catholic consensus itself.
Is Christ Proclaimed to Christians? The Impact of Scottish Evangelicalism on Hungarian Theology, Piety, and Praxis (1841-1945)
Authors: Kovács Ábrahám
Published: January 2020

This paper offers a concise overview of the impact made by Scottish evangelicalism of the Free Church of Scotland on the theology, piety and practice of Hungarian Reformed faith within the Austro-Hungarian Empire. They planted a kind of piety that was foreign, at least in its language and expressions, to most of the Hungarian Reformed people until the arrival of Scottish missionaries in 1841. Their conduct of practical Christianity, praxis pietatis materialised itself in Christian evangelism and social action. In this paper the focus is on the period between 1865 and 1914. To demonstrate the nature and form of this impact, first the paper outlines some key features of Scottish evangelicalism. Then, it investigates the theological and ecclesiastical impact of Scottish evangelicalism made through the establishment of voluntary societies and examines influence on the piety and praxis of Reformed faith in Hungary.
The Archaic, Archaic Communication and Psychic Figurability
Authors: Luca Daniela
Published: January 2020

In “Constructions in analysis” (1937), S. Freud compared the analyst’s work to that of the archaeologist searching among vestiges, with the big difference that the object of our work is alive, and working with it causes fear, pain and suffering. Last year, during a visit to Pompeii and Mount Vesuvius, impressed by the strangeness of the atmosphere, by people carbonised by lava, eternal statues in a shocking atemporality among the archaic objects and traces of the place, I picked up the thread of psychoanalytic reflections on such ruins, vestiges, the layers of “ash” also present in the human psyche and their relevance in the work of the analytic cure. How to communicate the unthinkable, the unsayable, the un-representable, the barely figurable? How to transform traces of your “ancestors’ ancestors’ ancestors”, even as passed down from Superego to Superego, or via inter-transgenerational transmissions? How to transform the formless into form?

From S. Freud to D. W. Winnicott, and W. Bion, from A. Green and J. McDougall, via D. Anzieu and R. Roussillon, the author is proposing to revisit the psychic vestiges as they are expressing during the analytic process.
Mourning, Separation, Mental Space
Authors: Nacu Anatol
Published: January 2020

The work of mourning and organization of the mental space may be seriously disturbed by the real loss of the object and the way how communication with the “still alive” objects is built. Certain obstacles in communication with significant people make the mental separation difficult. The problem of separation, individuation and building of somebody’s own mental space is linked to the way in which the child mourns in relation to the central objects of early childhood. Especially the real loss of a parental object during the early childhood implies a traumatic moment which will excessively dramatize the oedipal issues. In this context, the analysis of the infantile material and development of an analytical work, which would perlaborate the trauma of the loss under a full oedipal conflict of one of the parents, as well as the subjectivation difficulties deriving from this trauma are the indispensable elements of a psychoanalytic work.

Carrying out a research within the field being a part of a meta-science, which has the object of the whole education system with relevant educational processes at different levels, educational institutions, factors, dominant and trends in its development, resources, including human capital, and other elements together with the mechanisms of interaction between them, we use the term “educational comparative studies” as more adequate to define the research field mentioned above. It is stated that modernization of the national educational system in Ukraine in the framework of the world mainstream is not possible without unified and well-defined terminological bases, methodological foundations, principles and criteria for comparative studies that meet the current level of the science development and the needs of society. It is proved that the most effective way of fulfillment a comparative analysis of education systems in different countries is a detailed study of theory and practice of their teachers’ preparation for the systems under consideration. Having analyzed different scientific approaches to identifying criteria for a comparative study, the criteria on the development of teachers’ preparation are introduced. It is highlighted that the defined criteria will be applied in the research work on the development of special education teachers’ preparation systems in the USA, the UK and Ukraine. They are introduced in the article: legal support of the educational system for individuals with special needs; national and regional standards of special education teachers’ preparation; curriculums, methods, and technologies for special education teachers’ preparation; system of retraining and licensures of special education teachers; informative and scientific subsystem of special education system; subsystem of special education teachers’ pre-service preparation and in-field practical work management; financial and economic subsystem of training and retraining of special education teachers.

Authors: Zaika Artem
Published: January 2020

The article analyzes the tendencies in the development of digital literacy of citizens of European Union member states in educational institutions. The urgency of the study is driven by the need to develop the skills needed to communicate effectively in the epoch of 4 – the Industrial Revolution. This study focuses on analyzing the approaches needed to build digital literacy, as well as identifying its key development criteria in the education systems of the UK, Slovenia, the Netherlands, Lithuania and Estonia. Attention is drawn to the existing documents and programs that formulate conceptual trendsways for digital literacy across Europe. At the same time, in the European Union there is no common model that reflects the ways and methods of digital literacy, each country defining its priorities for achieving the goals. It is noted that digital literacy is characterized as one of the key skills for developing the professional competencies of a teacher and a competitive specialist. Based on the study of digital literacy experience abroad, it is possible to define a clear public policy focused on high levels of digital literacy and digital skills. The digitalization status of educational establishments and the population of Ukraine, which is defined as low, is compared. The main directions of the concept of development of the digital economy and society of Ukraine for 2018–2020 are described which aim to bridge the “digital divide” in comparison with the developed EU countries. It is concluded that it is precisely the educational institutions need significant reform. Based on the analysis of digital literacy approaches abroad, this study identifies priority areas for reforming education systems in the European Union in line with current labor market and digital society requirements.

Published: January 2020

The paper analyses certain aspects of organic agriculture and emphasises the need for an integrated approach in its research. The necessity of using ecologically safe agricultural production as a component of the development of modern civilized states is pointed out in the paper. The method of direct conductometry has been used to study the total mineral composition of plowed soils, which is considered as a component of “green” chemistry methods. The electrical conductivity of aqueous extracts of arable soils, in which mineral and organic fertilizers are applied, is measured. The obtained data vary between 10 and 220 μS. In the paper, for the first time, the regularities of fluctuations of the data of electrical conductivity of aqueous extracts of arable soils, in which various plant cultures had been grown, were revealed and mineral nitrogen fertilizers or organic fertilizers were introduced. Lower data of electrical conductivity are characteristic of plowed soils, in which mineral fertilizers are applied, which indirectly indicates their depletion. The advantage of using organic fertilizers as a necessary component of organic agriculture has been confirmed. It is noted that a promising area of the research is a complete use of an integrated approach to the organic agriculture being farmed in various European countries.
Development of the limit values of micronutrient deficiency in soil determined using Mehlich 3 extractant for Polish soil conditions. Part II. Rapeseed
Authors: Stanisławska-Glubiak Ewa , Korzeniowska Jolanta , Lipiński Wojciech
Published: January 2020

The aim of the study was to develop limit values for low microelement concentration in the soil, determined with the use of Mehlich 3 extractant for assessing their deficits in rapeseed crops. The values were prepared on the basis of 1944 fields with rapeseed, covering the whole Poland. In 2017, the samplers of Polish agro-chemical laboratories took soil samples and corresponding plant samples at the BBCH 30/31 stage. In the plant samples, the concentration of microelements was determined, and in the soil samples, apart from microelements, also pH, texture and the concentration of organic carbon and available phosphorus, were determined. Moreover, for each field, data on rapeseed yield were collected. Limit values were determined by two independent methods: 1) the method of regression equations and 2) the so-called high yield method. In the first case, the limit microelement concentration in the soil was calculated from the equation describing the relationship between the R/G bioaccumulation coefficient and a specific soil feature (n=1944). The bioaccumulation coefficient is a quotient of the concentration of a microelement in a plant (R) and its concentration in the soil determined by the Mehlich 3 (G) method. Limit values were calculated after substituting the critical concentration of microelements in the plant (R) to the equation, and subsequently, an appropriate conversion of the equation. The second method was based on the separation of a group of high yields ≥4.0 t ha−1 (n=755) from the whole data set. Then in this group, the lower quintiles (QU1) were calculated for the concentration of individual microelements in the soil determined in Mehlich 3 extract and adopted as limit values. It was found that QU1 is a good indicator of the lowest microelement concentration in the soil at which a yield of at least 4.0 t ha−1 can be obtained. The final limit values were worked out by averaging the values calculated by the equations and high yield method and their appropriate correction. In the combined soil sample collections for wheat and rapeseed (n=3865), the values were checked by evaluating the percentage of soils with microelement shortage separately for rape and wheat. The results of this evaluation were compared with the evaluation using the old system based on the 1 M HCl, which did not take into account the plant species.

Published: January 2020

This study aimed to investigate the effects of social network propaganda on exchange rate and also exchange rate fluctuations on Iran economic growth. This study uses annual data to analyse the long-run and short-run relationship between variables for the period of 1993–2018. Data were collected from the Central Bank of Iran. The autoregressive distributive lag (ARDL) method proposed by Pesaran, Shin, and Smith (2001) was used. The results of long-run analysis show that a 1% increase in negative propaganda of social media about the exchange rate leads to a 3.8% decline in long-run economic growth. Also, a 1% increase in exchange rate fluctuations results in a 3.5% decrease in economic growth. Research findings also indicate negative short-run impacts of social networks on the excitement of the foreign exchange market and, ultimately, on economic growth.
Ethics, Legal and Privacy Concerns for the Next Generation of Insurance Policies
Authors: Deck Klaus-Georg , Riedl Reinhard , Koumpis Adamantios
Published: January 2020

We present a set of hypothetical scenarios and cases where the need for access, sharing and processing of sensitive personal information increases the transparency of the customer to buyer relationship, although it may irreversibly damage the customer’s sphere of privacy. Highly personalised early risk prediction models for use by insurance companies to estimate the probability that a specific event (heart infarct) or a disease (diabetes) occurs in a given individual over a predefined time can enable earlier and better intervention, prevent negative consequences on a person’s quality of life and thus result in improved individual health outcomes. The challenge is to design, develop and validate new generations of comprehensive models that will be the result of a consensual process with the customers and will be based on artificial intelligence and other state-of-the-art technologies using multiple available data resources and will integrate them in personalised insurance policy pathways that empower the customers to actively contribute to their own individual health-risk mitigation and prevention.
A paradigm for the evolution of human features: Apes trapped on barren volcanic islands
Authors: Krill Allan George
Published: January 2020

The aquatic ape hypothesis for human evolution can account for all the traits that distinguish humans from chimpanzees. This scientific paradigm has been considered impossible. It would require that human ancestors maintained a semiaquatic lifestyle for millions of years, whereas hominin fossils indicate relatively dry terrestrial environments. Here I propose a marine aquatic evolution that is speculative, but compatible with all the fossil and genetic evidence. In this hypothesis, hominins evolved from chimpanzee-like apes that became stranded on proto-Bioko — new volcanic islands with no terrestrial foods available. The apes were forced to eat shellfish and seaweed. From wading in water on two legs to obtain food, their bodies evolved to become bipedal. Naked skin, blubber, and protruding noses were also aquatic adaptations. Brain-size increase resulted from marine fatty acid DHA. Some of these hominins escaped to mainland Africa and their bipedal descendants are recorded at the famous fossil sites. The volcanic islands grew and evolved into Bioko, and the hominins that remained there evolved into Homo sapiens. They gave up their marine diet and semiaquatic habitat after food became available on the evolving island. Then, during one of the low sea-level stands in the Pleistocene epoch, humans walked to the mainland on the emergent Bioko land bridge. Unlike earlier aquatic ape ideas, the Bioko scenario can be tested by DNA. If the human genome includes a retrovirus that is otherwise only found in endemic animals on Bioko, it would show that our ancestors came from there. Unfortunately, Bioko and west-central Africa are not interesting to traditional paleoanthropologists, because they do not contain fossils.

Bu çalışmanın amacı, üç farklı bitki familyasına ait olan kakule (Trigonella foenum-graecum, Fabaceae), Ayçiçeği (Helianthus annuus, Asteraceae) ve çemen otu (Elettaria cardamomum, Zingiberaceae) tohumu ekstraktlarının in vitro koşullar altında, sazan balığı (Cyprinus carpio L.) sperm hücrelerinin motilite parametrelerine ve oksidatif stres durumlarına etkilerini belirlemektir. Bu amaçla, %0,1, %0,5, %1 ve %2 oranlarındaki tohum ekstratları ile muamele edilen sperm örnekleri 4Â°C‘de muhafaza edilerek, 2. ve 48. saatte ölçümleri yapılmıştır. Sperm motilite parametrelerinden kavisli hareket hızı (VCL), ortalama hızı (VAP), ileri doğru doğrusal hareket hızı (VSL), doğruluk (STR), doğrusallık (LIN), sperm başı titreşim hareketi (WOB) tayinleri bilgisayar yardımlı sperm analizi (CASA) sistemi ile gerçekleştirilmiştir. Elde edilen sonuçlara göre, Ayçiçeği ve çemen otu tohum ekstraktları, test edilen oranların tamamında motilite parametrelerini azaltıcı yönde tesir etmiştir. Buna karşın, 48. saatte %0,5 kakule tohumu ekstraktı kontrol grubu dâhil tüm gruplara kıyasla motilite parametrelerini yükseltmiştir. Ayrıca bu grupta, oksidatif stres göstergesi olarak ölçülen TBARS değerleri azalmıştır. %2 tohum ekstraktlarının tümü negatif olarak sperm örneklerini etkilemiştir. Özellikle, %2 Ayçiçeği tohum ekstratı grubu yüksek oksidatif strese neden olmuştur. Bu çalışmanın sonuçları, 4Â°C‘de sazan balığı sperm muhafazasında, ayçiçeği ve çemen otuna göre kakule tohum ekstraktının kullanımının daha uygun olduğunu göstermiştir.
Effect of Production Systems for Laying Hens on Hen Welfare
Authors: Tainika Brian , Şekeroğlu Ahmet
Published: January 2020

This review article discussed the effects of various production systems on the welfare of laying hens. The global egg production capacity has been increasing with the evolving production systems which are driven by the consumer preferences. In developed countries, the egg industry has shifted from focusing on quantity and quality of eggs to asking questions of how these eggs are produced. Animal welfare issues emphasized by consumers in these countries led to the banning of conventional cages as seen by European Union in 2012. Such legal measures have uplifted research in various alternative production systems which are thought to be animal friendly. Countries that have adjusted to alternative systems such as free range are registering an increase in the number of free range eggs which is a positive sign for an industry that is willing to adapt and move forward. However, in developing countries, conventional cages are still being used because they are fundamental to the quantity of egg production which is a success indicator of the egg industry. In addition, lack of awareness within the consumers and local producers that birds are sentient has not helped the poultry industry in such countries. However, the alternative production systems have also not fulfilled all the behavioural needs of the animals and, hen welfare issues such as keel and bone damage are common in enriched and perched systems. Also, the high prevalence of diseases and parasites are observed with significant levels in litter floor and outdoor systems an issue attributable to the direct contact between birds and soil or faces. Due to the continuing welfare issues in all laying hen production systems, it is suggested that in addition to genetic selection for traits like bone strength, reduced feather pecking, research should combine both the modification of equipment‘s or materials used in each production system and environmental factors such as illumination and temperature as an alternative to improve hen welfare.
“Where’s the I-O?” Artificial Intelligence and Machine Learning in Talent Management Systems
Authors: Gonzalez Manuel , Capman John , Oswald Frederick , Theys Evan , Tomczak David
Published: January 2020

Artificial intelligence (AI) and machine learning (ML) have seen widespread adoption by organizations seeking to identify and hire high-quality job applicants. Yet the volume, variety, and velocity of professional involvement among I-O psychologists remains relatively limited when it comes to developing and evaluating AI/ML applications for talent assessment and selection. Furthermore, there is a paucity of empirical research that investigates the reliability, validity, and fairness of AI/ML tools in organizational contexts. To stimulate future involvement and research, we share our review and perspective on the current state of AI/ML in talent assessment as well as its benefits and potential pitfalls; and in addressing the issue of fairness, we present experimental evidence regarding the potential for AI/ML to evoke adverse reactions from job applicants during selection procedures. We close by emphasizing increased collaboration among I-O psychologists, computer scientists, legal scholars, and members of other professional disciplines in developing, implementing, and evaluating AI/ML applications in organizational contexts.
Love in parenting, upbringing and education of the infants (Contribution to the history of institutional pre-school education in the 19th century using the example of Trnava town)
Authors: Lopatková Zuzana
Published: January 2020

The establishment of pre-primary educational institutions, brought recognition to pre-schools in most countries as the most appropriate place for the preparation of a child for life and school. From the beginning of institutional or private efforts to educate young children in theory and practical subjects, there were efforts to conceive pre-school educational institutions on the principles of holistic development with a deep understanding of the world of children and their psyche, as well as to prepare suitable teachers for these children. The existence of a pre-school in Trnava, demonstrates that this was in place from the start of the 19th century, and especially in activities of teacher Anthony Rehlingen.

Authors: Sun Guangchi , Yang Baozhu , Yin Gui , Zhang Hanping , Liu Qi
Published: January 2020

Aqueous zinc batteries are considered as one of the most promising energy storage systems for large-scale energy storage and wearable electronics, owing to their low cost and intrinsic safety. However, cathode materials that can reversibly host Zn2+ are still less. Here, we demonstrate that two N-containing organic compounds, hexamethoxy hexaazatrinaphthylene (HMHATN) and hexaazatrinaphthylene (HATN), used as cathodes can exhibit excellent reversible Zn2+ storage capability with fast kinetics and the high capacity of 542 and 963 mA h g-1, respectively. The Zn//HMHATN and Zn//HATN full batteries display the high energy density of 160 and 221.6 W h kg-1, respectively, and long-term cycling stability. Further, we investigate the mechanism of Zn2+ storage in the cathodes. More importantly, the flexible aqueous Zn//HMHATN and Zn//HATN batteries fabricated also have high capacity, long-term cycling life and impressive energy density, displaying its application prospect in wearable electronics. Our work opens a new system for finding organic cathode materials used in aqueous zinc batteries.

Microstructure and properties of ZrO2 ceramic and Ti-6A-4V alloy vacuum brazed by Ti-28Ni filler metal
Authors: Hong Li , Xuan Liu , Haixin Huang
Published: January 2020

Reliable ceramics/metal joints have an extensive application in the aerospace and biomedical area. However, ZrO2ceramic has not been investigated systematically compared to the Si3N4and Al2O3ceramic. Therefore, successful brazing of ZrO2ceramic and Ti-6A-4V alloy was achieved by using a binary active Ti-28Ni filler metal in this paper. The effect of holding time on the microstructure of ZrO2 ceramic/filler metal interface and mechanical properties of brazed joints was investigated. The results indicated that the representative interfacial microstructure was ZrO2ceramic/Ti2O/Ni2Ti4O/Ti-rich phase/Ti2Ni+α-Ti. With the increase of holding time, the thickness of Ti-rich layer in the interface of ZrO2/Ti-6Al-4Vjoint decreased obviously due to the diffusion of Ti atoms. Substantial brittle intermetallic compounds Ti2Ni and Ni2Ti4O were formed in the joint, which were detrimental to the mechanical properties of the brazed joints. The maximum shear strength of joint was 112.7 MPa when brazed at 1060 °C for 10 min.

Joruk is a traditional fishery product made by spontaneous fermentation process using
lactic acid bacteria by salting method, followed by fermentation process. Hydrolysis of
proteins with the pepsin and a combination of pepsin and trypsin enzymes by in vitro can
produce bioactive peptides. The aims of this study were to investigate the change of
soluble protein and lactic acid content in oci fish joruk (Rastrelliger kanagurta) and to
determine the influence of the enzyme hydrolysis on the antioxidant activity of joruk. The
raw material used in this highest study was the oci fish obtained from Gorontalo,
Indonesia. The produced joruk was added with the concentration of palm sugar 10%, 20%
and 30% then fermented for 8 days, 10 days and 12 days. Protein hydrolysis using the
pepsin enzyme and a combination of pepsin and trypsin enzyme. The results showed that
the addition of palm sugar and fermentation time can reduce soluble protein and increase
the lactic acid content. The highest antioxidant activity was found in joruk hydrolysate
that hydrolyzed by pepsin enzyme with the addition of 30% palm sugar and 12 days
fermentation, with a value of 5.28%.

Published: January 2020

O presente artigo propõe a elaboração de um panorama contemporâneo sobre as relações entre movimentos sociais e comunicação a partir do recorte proporcionado pela eclosão da crise do capitalismo iniciada ao final da primeira década do século XXI. Pretendemos contribuir para uma reflexão que seja capaz de problematizar o papel e o sentido da comunicação para a constituição desses movimentos, levando em consideração não apenas a utilização das tecnologias digitais como instrumento mobilizador e os veículos e peças de comunicação por eles produzidos, mas também buscando compreender que questões, referentes à natureza e inserção desses movimentos no capitalismo contemporâneo, podem ser reveladas a partir da identificação da importância assumida pela comunicação e pela cultura em sua constituição.

To increase the level of information transparency of economic entities is one of the most important tasks for the development of the domestic financial market within the framework of the state national programs implementation. The article provides a detailed review of the current methods and practices of reputable international and Russian rating agencies and professional communities for assessing information transparency of economic entities, it also defines and systemizes the basic characteristics disclosed by companies. The article identifies the main patterns and positive trends in the development of information transparency of Russian business over the past ten to fifteen years. The analysis shows that there has been a positive trend in disclosures in Russian business, but the level of transparency is still far from the level of Western companies. The applied methods vary greatly in the choice of indicators and assessment criteria, depending on the target nature and the specifics of the study, so determining the optimal level of information transparency is very subjective. Since transparency measurement largely depends of the branch of industry, the authors propose to develop this concept taking into consideration the special features of different segments such as credit organizations, financial companies, leasing organizations and others.

Currently, the Russian Federation invests heavily in the production of products under the state defense order (hereinafter — SDO). The head executors and executors of the state budget are obliged to ensure separate accounting of the results of financial and economic activities for each state contract. The article is devoted to the development of methodological support for separate accounting of performance at enterprises which are the executors of the state budget. The research methodology is an analysis of existing methodological approaches to separate accounting of financial results of the SDO and the construction of the author’s own methodology on their basis. The article offers recommendations on the organization and methodology of separate accounting of the results of financial and economic activity by the organizations-executors of the SDO. The author’s definition of the term “separate accounting of the results of financial and economic activities in SDO” is given. The form of the register of accounting for grouping of the actual costs for execution of the SDO is developed. The developed recommendations for management job order costing accounting, clearance accounting, classification of costs by types, and the formation of registers of analytical accounting will allow the organizations-executors of the SDO to keep separate records in accordance with the regulatory requirements and to obtain information on the financial results of each contract at any given time.
Variabilidade da Dengue e do Clima em Porto Alegre/RS de 2012 a 2017
Authors: Collischonn Erika , Maio Bianca Marques , Brandolt Ricardo
Published: January 2020

O El Niño/Oscilação Sul (ENOS) é uma oscilação conjunta oceano-atmosfera, que altera a Temperatura da Superfície do Mar (TSM), a pressão, o vento e a convecção tropical, principalmente no Oceano Pacífico, porém com reflexos na circulação atmosférica e no padrão de distribuição da precipitação em outras áreas do planeta, incluindo o sul do Brasil, conforme já comprovado por vários autores. Essa alteração de padrões pode aumentar o número de pessoas expostas a doenças, como a dengue, aumentando a probabilidade de surtos ou epidemias. Neste trabalho, o recorte temporal escolhido, de 2012 a 2017, abrange os dois anos em que mais casos de dengue autóctone ocorreram em Porto Alegre (2013 e 2016). Para o período, analisaram-se variabilidades a partir dos seguintes dados: Índice Niño 3.4 (NOAA); médias e totais mensais de elementos meteorológicos e as normais climatológicas 1981-2010 de Porto Alegre (WMO 83967- INMET); casos confirmados de dengue por semana epidemiológica e ano (SINAN-RS); dias com presença de jatos de baixos níveis (JBN) sobre Porto Alegre (Projeto Rios Voadores e INPE/CPTEC). A partir da organização destes dados, foi constatada uma correspondência entre o El Niño muito forte ocorrido em 2016, a presença quase constante dos JBN sobre Porto Alegre, precipitação bem superior à normal e o maior número de casos de dengue autóctone já registrado até então. Discute-se também as diferenças e semelhanças deste ano com o de 2013, que foi o segundo ano em registros de dengue autóctone.  Variability of Climate and Dengue Fever Cases in Porto Alegre/RS from 2012 to 2017 A B S T R A C TThe El Niño / Southern Oscillation (ENSO) The El Niño-Southern Oscillation (ENSO) cycle causes ripples through the global climate, changing air currents and rainfall patterns, The effect on the climate of southern Brazil was evidenced by several authors. The shifts in Niño years can increase the number of people exposed to a disease, such as dengue, increasing the likelihood of an outbreak. In this work, we analyzed a period of time that covers the two years in which more cases of autochthonous dengue fever occurred in Porto Alegre (2013 and 2016). For this period, variability was analyzed from the following data: Niño 3.4 (NOAA), monthly mean and cumulative meteorological data and climatological normal 1981/2010 of Porto Alegre (WMO 83967- INMET); confirmed cases of dengue fever per epidemiological week and per year (SINAN-RS); days with presence of low level jets (JBN) over Porto Alegre (INPE/CPTEC). The organization of these data showed correspondence between the very strong El Niño occurred in 2016, the almost constant presence of the JBN over Porto Alegre, the most intense and frequent precipitation, and the highest number of autochthonous dengue cases ever recorded. We also discuss the differences and similarities of this year with that of 2013, which was the second year in autochthonous dengue fever records.Keywords: El Niño, Low Lever Jet, precipitation, temperature, wind, dengue fever.
