Authors: Nareddy Vishnu Anjan , Varun M. Sai , M.V. Nagabushana
Published: June 2018

Background: Iron deficiency anaemia still remains the most common cause of anaemia not only in India but also world over. According to world heath report, there are 1,788,600 people in this world suffering from Iron deficiency anaemia. Iron deficiency anaemia is foremost prevalent disease-causing morbidity in world and therefore it is always absolutely necessary to detect this particular condition in early stages before the eventual development of various dreadful complications like Heart failure and Myocardial infarction. The aim of the study is to find incidence of iron deficiency anaemia in patients with hypo proliferative anaemia presentation, with a possible iron deficient state, by analyzing the haematological and biochemical parameters.Methods: The study was conducted from November 2017 to May 2018 for a period of 6 months which included 50 subjects from both sex groups, aged 20-80 years with the diagnosis of hypo proliferative anaemia.Results: The study results indicate that females (60%) were significantly overrepresented compared to males (40%). Of the 50 subjects 38% were in stage of negative iron balance (stage1) and 32% were in stage of iron deficient erythropoiesis(stage2) and 30% were in normal stage.Conclusions: This Observational study showed a majority of patients with hypo-proliferative anaemia presenting at early stages of negative iron balance and iron deficient erythropoiesis thereby indicating the importance of initiating iron therapy at an early stage even without correlative iron studies.

Published: June 2018

Three- dimensional (3D) reconstruction obtained by using multidetector computed tomography (MDCT) images have widely been used in anatomical studies. Thorax is one of the most important body cavities necessary for the protection of lungs and heart in mammals. Two adult mongooses (1 male, 1 female) obtained from traffic accidents were used in this study. The images obtained from MDCT were stacked and 3D reconstruction of thorax was performed by overlaying images using a 3D modeling software (Mimics 13.1). Some measurements of thoracic cavity, lungs and sternum were taken from the reconstructive images of mongoose and indexes were calculated from these measurements. The morphometric parameters were recorded for both sexes. From the study, it could be concluded that the thoracic cavity, lungs and sternum imagings and findings revealed by 3D modeling techniques can be utilized for anatomical training of wild animals. This study is expected to help in the diagnosis and treatment of thorax diseases in wild animals.

Published: June 2018

The present study evaluated the effects of dietary supplementation of chitooligosaccharide (COS) on egg production, egg quality and blood profiles in laying hens. A total of 192 Hy-Line Brown laying hens (initial age- 46 weeks) were allocated to one of four treatments with eight replications per treatment and six adjacent cages as replication for eight-weeks study. Dietary treatments consisted of CON, basal diet; COS1, CON + 0.1% COS; COS2, CON + 0.2% COS; and COS3, CON + 0.3% COS. Linear improvement (p Lass Than 0.05) was observed in egg quality and high-density lipoprotein cholesterol (HDL/C) concentration at subsequent weeks. In week 8, linear (P=0.04) improvement was observed in haugh unit of egg with the increase in the dose of COS. In addition, linear effects (p Lass Than 0.05) on eggshell thickness at week 3, 5, 6, 7 and 8 were detected as the level for increased COS. In conclusion, the supplementation of COS in laying hens diets linearly improved the egg quality and the HDL/C concentration. Thus, COS has the potential to be used as a substitute to antibiotics in layer hen’s diets.

Phosphorus (P) sources are limited around the globe making it unsustainable with present farming practices. This necessitates the development of more phosphorus efficient crops while monitoring P status. Groundnut (Arachis hypogaea L.) is a major crop in Southern Andhra Pradesh, India where soils are light textured and less fertile. Twenty groundnut genotypes were evaluated under a pot culture experiment conducted at Regional Agricultural Research Station, Tirupati, Andhra Pradesh, India during kharif, 2016 grown using standard crop recommended practices in P-sufficient (control) and in P-deficient conditions. Leaf Acid phosphatase activity and leaf P content were monitored after 60 days of sowing while kernel P and pod yields were recorded at harvest and estimated using standard protocols. Results showed that under P deficient conditions, genotypes TCGS 1616, TCGS 1622, TCGS 1624, TCGS 1517 and Greeshma had higher leaf P accumulation (between 0.20 % to 0.24 %) in comparison to others. Genotypes TCGS 1616, TCGS 1624, and TCGS 1517 reported high kernel P when compared to others under P starved conditions. Likewise under deficient soil P conditions, TCGS 1528, TCGS 1624, TCGS 1517 and Greeshma (range 2.71-4.45 µmoles hr-1g-1) demonstrated having lower leaf acid phosphatase content in leaves when compared to other genotypes. Only TCGS 1624, TCGS 1616 and Greeshma had lower leaf acid phosphatase while at the same time having higher accumulation of leaf P and highest pod yield followed by TCGS 1517 suggesting that P starvation was better coped by these genotypes and hence can be recommended in soils deficient in P. Leaf acid phosphatase activity correlated negatively with P content in leaves (r = -0.73) similar to those reported for soybean cultivars in Brazil. There is potential for breeders in accelerating identification of markers to specific traits that would be suitable for monitoring P status and manage nutrient application.

Authors: Askin Deniz
Published: June 2018

This study aims to analyze the process of changing spatial belongings of migrants’ generations. The First generation who moved out from Eastern and Southeastern of Turkey haven’t cut their communication with their hometown. On the contrary, they have built new belonging relations with the host culture. This is the exact opposite of the second generation. The second generation, who are children of the first generation, have built sense of belonging to İnegöl where they live. Also the second generation have prevented their parents from returning to their hometown. It shows that children and their parents have been living in the different worlds although they live in the same homes. This study has been conducted on migrants living in Huzur Neighborhood, İnegöl, Bursa. Empirically, I conducted in depth interviews and focus groups discussions with 30 migrants to capture the changing spatial belongings of the two generations of migrants.

This study investigates the power of psychological variables of depression, self-esteem and impulsivity as well as social variables of perceived social support and subjective socio-economic status in predicting risky sexual behaviours. To accomplish this study, all those individuals who were commuting to the Behavioural Diseases Counseling Center of Urmia over the last 6 years were considered and then, 80 individuals were selected as the research sample using available sampling method. The Rosenberg Self-esteem Scale, researcher-made scale for assessing risky sexual behaviours, Beck depression inventory, Barratt impulsivity scale, Zimet perceived social support scale and researcher-made questionnaire of subjective social status were used in this study. The results showed that all the variables have had significant roles in predicting the risky sexual behaviours. Depression has had the most power to predict risky sexual behaviours. After that self-esteem, perceived social support and subjective social status could predict important parts of variances in the risky behaviours (R2 = 0.57). Regarding the mentioned results, it may be concluded that psychological factors to commit risky sexual behaviours. Thus, personal factors-based preventive and therapeutic programmes for sexual risky behaviours for youth are recommended.

Strategy and leadership practices across cultures world-wide
Authors: Garg Shaifali
Published: June 2018

Most companies develop their strategy around key strengths or core competencies, especially how to coordinate diverse production skills and integrate multiple streams of technologies. But leadership often is credited for the success or failure of international operations. Effective leadership styles and practices in one culture are not necessarily effective in others. For examples, the leadership approach used by effective US managers would not necessarily be the same as that employed in other parts of the world even within the same country. Effective leadership tends to be very situation specific.However, certain leadership styles and practices transcend international boundaries. This paper gives a birdâ€™s eye view of Japanese versus U.S. Leadership styles.Keywords: Leadership, strategy, worldwide.

Z medkulturno raziskavo smo želeli raziskati stopnjo subjektivnega blagostanja in hierarhijo vrednot pri študentih iz Češke in Malte. Zanimala nas je tudi povezanost med vrednotami ter kognitivno in čustveno komponento subjektivnega blagostanja. V vzorec (N = 280, starost 18 do 30 let, M = 21,9 let, SD = 2,5) smo vključili 165 čeških in 115 malteških študentov, ki so izpolnili Lestvico zadovoljstva z življenjem, Lestvico srečnosti in Vprašalnik ovrednotenja področij življenja. Rezultati so pokazali, da se češki in malteški vzorec nista pomembno razlikovala v stopnji izraženosti zadovoljstva z življenjem in sreči. Pokazale pa so se pomembne razlike med vzorcema v hierarhiji vrednot in njihovi povezanosti s subjektivnim blagostanjem. Raziskava je pokazala, da se kulture lahko razlikujejo v pomembnosti, ki jo pripisujejo posameznim vrednotam, ter da lahko kognitivno in čustveno komponento subjektivnega blagostanja napovedujemo z različnimi spremenljivkami glede na posamezno kulturo.
Transient Coupling of Swab/Surge Pressure and In-Situ Stress for Wellbore-Stability Evaluation During Tripping
Authors: Zhang Feifei , Kang Yongfeng , Wang Zhaoyang , Miska Stefan , Yu Mengjiao , Zamanipour Zahra
Published: June 2018

This paper identifies wellbore-stability concerns caused by transient swab/surge pressures during deepwater-drilling tripping and reaming operations. Wellbore-stability analysis that couples transient swab/surge wellbore-pressure oscillations and in-situ-stress field oscillations in the near-wellbore (NWB) zone in deepwater drilling is presented.

A transient swab/surge model is developed by considering drillstring components, wellbore structure, formation elasticity, pipe elasticity, fluid compressibility, fluid rheology, and the flow between wellbore and formation. Real-time pressure oscillations during tripping/reaming are obtained. On the basis of geomechanical principles, in-situ stress around the wellbore is calculated by coupling transient wellbore pressure with swab/surge pressure, pore pressure, and original formation-stress status to perform wellbore-stability analysis.

By applying the breakout failure and wellbore-fracture failure in the analysis, a work flow is proposed to obtain the safe-operating window for tripping and reaming processes. On the basis of this study, it is determined that the safe drilling-operation window for wellbore stability consists of more than just fluid density. The oscillation magnitude of transient wellbore pressure can be larger than the frictional pressure loss during the normal-circulation process. With the effect of swab/surge pressure, the safe-operating window can become narrower than expected. The induced pore pressure decreases monotonically as the radial distance increases, and it is limited only to the NWB region and dissipates within one to two hole diameters away from the wellbore.

This study provides insight into the integration of wellbore-stability analysis and transient swab/surge-pressure analysis, which is discussed rarely in the literature. It indicates that tripping-induced transient-stress and pore-pressure changes can place important impacts on the effective-stress clouds for the NWB region, which affect the wellbore-stability status significantly.
Proppant-Conductivity Testing Under Simulated Reservoir Conditions: Impact of Crushing, Embedment, and Diagenesis on Long-Term Production in Shales
Authors: Mittal Abhinav , Rai Chandra S. , Sondergeld Carl H.
Published: June 2018

Hydraulic fractures act as conduits connecting a wellbore to nanodarcy-permeability unconventional reservoirs. Proppants are responsible for enhancing the fracture conductivity, and they help in maintaining high production rates. This study is focused on the measurement of long-term conductivity of proppant packs at simulated reservoir-temperature and pressure conditions. Various conductivity-impairment mechanisms such as proppant crushing, fines migration, embedment, and diagenesis are investigated.

Testing was performed with a conductivity cell that allows simultaneous measurement of fracture compaction and permeability. The proppant-pack performance during compression between metal and shale platens was compared. The proppant-filled fracture (concentration of 0.75–3 lbm/ft2) is subjected to axial load (5,000 psi) to simulate closure stress. Brine (3% NaCl + 0.5% KCl) is flowed through the pack at a constant rate (3 cm3/min) at 250°F during an extended duration of time (10–60 days). In this study, Ottawa sand proppant was used between platen facies fabricated from Vaca Muerta and Eagle Ford shales.

Testing between metal platens indicated that the reduction in permeability with 20/40-mesh Ottawa sand (≈30% during 12 days) was less than that of 60/100-mesh Ottawa sand, which suffered a 99% reduction in only 4 days.

Measurements with 20/40-mesh Ottawa sand between shale platens were conducted at 1.5 lbm/ft2. During a duration of 10 days, the Eagle Ford platens proppant pack exhibits a greater reduction in permeability, in comparison with Vaca Muerta platens. The normalized compaction for Eagle Ford shale platens is 20% more than Vaca Muerta platens because of greater proppant embedment. Particle-size analysis and scanning-electron-microscopy (SEM) images verify proppant crushing, fines migration, and embedment as dominant damage mechanisms. These factors are observed to depend on the testing of shales. The results suggest a substantial degradation of permeability during the initial 5 days of testing, after which the permeability appears to stabilize. Crushed proppant and dislodged shale-surface particles contribute to the fines generated; a greater concentration of fines is observed downstream.

In a separate study between Vaca Muerta platens, under similar closure stress and temperature conditions at 2-lbm/ft2 proppant concentration, the permeability reduced by almost three orders of magnitude during a duration of 60 days. It was also observed that growth of diagenetic smectite is accelerated by making the fluid more basic (pH of 10).

Deterioration models can be successfully deployed only if decision-makers trust the modelling outcomes and are aware of model uncertainties. Our study aims to address this issue by developing a set of clearly understandable metrics to assess the performance of sewer deterioration models from an end-user perspective. The developed metrics are used to benchmark the performance of a statistical model, namely, GompitZ based on survival analysis and Markov-chains, and a machine learning model, namely, Random Forest, an ensemble learning method based on decision trees. The models have been trained with the extensive CCTV dataset of the sewer network of Berlin, Germany (115,258 inspections). At network level, both models give satisfactory outcomes with deviations between predicted and inspected condition distributions below 5%. At pipe level, the statistical model does not perform better than a simple random model, which attributes randomly a condition class to each inspected pipe, whereas the machine learning model provides satisfying performance. 66.7% of the pipes inspected in bad condition have been predicted correctly. The machine learning approach shows a strong potential for supporting operators in the identification of pipes in critical condition for inspection programs whereas the statistical approach is more adapted to support strategic rehabilitation planning.

Published: June 2018

Population explosion in urban settings usually exerts enormous pressure on existing water supply systems. The result is that overall water demand is usually not satisfied. This study evaluated the performance of Wadata sub-zone water distribution system with respect to pressure, velocity, hydraulic head loss and nodal demands using WaterCAD and Epanet. There was no statistical difference between the results of Epanet and WaterCAD, however, Epanet produced slightly higher results of pressure and velocity in about 60% of all cases examined. About 19 percent (18.52%) of the total number of nodes analyzed had negative pressures while 69 percent (69%) of the nodes had pressures less than the adopted pressure for the analysis. These negative pressures indicate that there is inadequate head within the distribution network for water conveyance to all the sections. About 88 percent (87.7%) of flow velocities in the pipes were within the adopted velocity while around 12 percent (12.3%) of the velocities exceeded the adopted velocity. These excess velocities are partly responsible for the leakages and pipe bursts observed at some points within the system. The results in this study revealed that the performance of the water distribution system of Wadata sub-zone under current demand is inefficient.

OLAPS: Online load-balancing in range-partitioned main memory database with approximate partition statistics
Authors: Belayadi Djahida , Hidouci Khaled-Walid , Bellatreche Ladjel
Published: June 2018

Modern database systems can achieve high throughput main-memory query execution by being aware of the dynamics of highly parallel hardware. In such systems, data is partitioned into smaller pieces to reach a better parallelism. Unfortunately, data skew is one of the main problems faced during parallel processing in a parallel main memory database. In some data-intensive applications, parallel range queries over a dynamic range partitioned system are important. Continuous insertions/deletions can lead to a very high degree of data skew and consequently a poor performance of parallel range queries. In this paper, we propose an approach for maintaining balanced loads over a set of nodes as in a system of communicating vessels, by migrating tuples between neighboring nodes. These frequent (or even continuous) data transfers inevitably involve dynamic changes in the partition statistics. To avoid the performance degradation typically associated with this dynamism, we provide a solution based on an approximate Partition Statistics Table. The basic idea behind this table is that both clients and nodes may have an imperfect knowledge about the effective load distribution. They can nevertheless locate any data with almost the same efficiency as using exact partition statistics. Furthermore, maintaining load distribution statistics do not require exchanging additional messages as opposed to the cost of efficient solutions from the state-of-art (which requires at least O(logn) messages). We show through intensive experiments that our proposal supports efficient range queries, while simultaneously guaranteeing storage balance even in the presence of numerous concurrent insertions/deletions generating a heavy skewed data distribution.

Published: June 2018

Relational databases are one of the pillars of information systems and as a consequence conceptual and logical design can be seen as the foundation of almost every application regardless of the platform. Nevertheless, little research has been done so far on the effectiveness of teaching approaches to database basic concepts and design. This paper introduces a multi-level experimental study developed to examine the effectiveness of learning database fundamentals, depending on the notation used for conceptual design. The main experiment was carried out at a higher education institution. We developed different experimental instruments to evaluate the effectiveness of a teaching approach using Barker or Bachman notation for conceptual database design. In contrast to Barker notation, Bachman notation incorporates elements of logical design (i.e. foreign keys) in the conceptual design level. Students? achievements were examined with regard to influencing factors throughout the learning process. Introducing the Bachman notation and a manual transformation from a conceptual into a logical data model, could increase students? understanding of conceptual, logical and relational data model concepts. We found that the notation used during the learning process has an impact on students? achievements. Moreover, students achieved better results when solving tasks presented with a notation that incorporates elements of logical design into the conceptual level. Finally, we required the use of manual transformation from a conceptual into a logical data model and the results confirmed an increase in students? understanding.

[ReOLCl3(OH2)], [ReOL(SCN)2Cl(OH2)].H2O and [ReOL(SCN)Cl2(OH2)] (where L =
2-benzimadazolethione), yielded the corresponding ammine and/or amine
complexes, [Re2O3L2(NH3)2(NH2)2]Cl2 (I), [Re2O2L3(NH3)2(NH2)4]Cl2(II),
[Re2O3L2(NH3)2 (NH2)4].H2O (III), [Re2O3L4(NH2)4] (IV),
[Re2O3L2(NH3)2(NH2)4] (V), [Re2O3L2 (SCN)4(NH3)2] (VI) and
[Re2O3L2(Thio)2(NH2)4] (VII), respectively, (Thio = thiourea) where ammonia
gas has replaced other ligands such as chlorine and water. In complex VII
thiourea replaced the thiocyanate group in the start complex through its
reaction with ammonia gas. The obtained ammine and/or amine of rhenium(V)
complexes have been observed to decompose through several isolatable, as
well as non-isolatable complex species as intermediates during heating.
[Re2O3L4], [Re2O3 L2(NH2)4] and [Re2O3L2(SCN)4], were synthesized
pyrolytically in the solid state from the corresponding parent oxorhenium
complexes. The electronic absorption spectra and magnetic moments of the
complexes show that the Re(V) cation has an octahedral configuration. IR, 1
H-NMR spectroscopy, conductivity measurements and thermal analysies show
that ammonia and thiourea behave as neutral monodentate ligands, SCN- and
NH2- as monodentate monoanionic ligands, the organic ligand (L) as a
neutral monodentate or bidentate ligand towards the metal cation.

Published: June 2018

By combining the techniques of electrochemical slow potentiodynamic, AC
impedance and atomic force microscopy (AFM), it was shown that the
differences in the anodic dissolution rates of Al in 0.5 NaCl solutions as
measured experimentally in the potential region between the corrosion and
pitting potential, are mainly due to differences in surface roughness of the
electrodes used. It was shown that mechanical grinding and polishing of the
electrode surface with emery paper (400 grit) and alumina polishing powder
(? 0.25 ?m) can produce surfaces differing by a factor of 6 in the roughness
factor Ra. By using AFM estimates of the roughness factors a true electrode
capacitance of 4.63?C cm-2 and thickness dox ? 2.0 nm for the barrier
layer of the surface film was estamited. The outer part of the film is
porous, partly as amorphous Al(OH)3, or crystalline bayerite (Al2O3?3H2O).

Low-lying singlet and triplet electronic states of the BeO molecule are
calculated by means of the quantum chemical ab initio method. It was found
that all states in the energy range from 0 to 50000 cm-1 are of valence
character. Particular attention was paid to the investigation of the
dissociative behavior of the states considered. The vibrational structure of
the A 1P ? X1S and B 1S+ ? X1S+ spectral systems was calculated.

Kielitietoisuutta kielentämällä – kieliopin tehtävätyyppien kehittäminen
Authors: Rättyä Kaisu , Kulju Pirjo
Published: June 2018

Tiivistelmä

Perusopetuksen opetussuunnitelman perusteissa (POPS2014) mainitaan tavoitteeksi, että oppilaan kielitietoisuus vahvistuu, oppilas innostuisi tutkimaan kieltä ja sen variantteja ja että oppilas harjaantuisi käyttämään käsitteitä, joilla kielestä voidaan puhua. Kielitiedon opetuksesta on kuitenkin esitetty varsin vähän konkreettisia pedagogisia menetelmiä. Tämän opetuksenkehittämistutkimuksen tavoitteena on luokitella ja kehittää kielitiedon tehtäviä soveltaen Krathwohlin (2002) tavoitetaksonomia-ajattelua siten, että ensimmäisen tason tavoitteena on käsitteiden muistaminen, toisen tason käsitteiden ymmärtäminen ja käyttäminen suppeissa tehtävissä, kolmannen käsitteiden välisten suhteinen ymmärtäminen ja neljännen tason tavoitteena on käsitteiden soveltaminen tekstin analyysissä. Lisäksi mallissa sovelletaan kielentämistä pedagogisena menetelmänä. Esittelemämme tehtävätyypit voidaan luokitella tunnistamis-, tuottamis-, suhteuttamis- ja analyysitehtäviin sekä ilmiöön kohdistuviin tutkivan oppimisen tehtäviin.

Objetivo: identificar os métodos contraceptivos prescritos por Enfermeiros da Estratégia Saúde da Família (ESF) durante o período puerperal. Metodologia: estudo transversal, realizado em unidades básicas de saúde de Teresina - Piauí, com enfermeiros que fazem parte das equipes de ESF destas unidades. A coleta foi realizada entre os meses de março e abril de 2017, com 59 enfermeiros. Resultados: a minipílula foi o método prescrito com maior frequência (74,6%) por estes profissionais; em ordem decrescente, o segundo mais prescrito foram os preservativos (55,9%), seguido dos injetáveis (42,4%) e outros (15,3%). O método mais citado prescrito por médicos em conjunto com os enfermeiros foram os preservativos (78,8%), seguidos por outros (77,8%), minipílula (75,0%) e injetáveis (72,0%). Conclusão: o curto intervalo entre gestações não é recomendável, pois pode desencadear a possibilidade de morbimortalidade materna e infantil. A pesquisa esclareceu as práticas adotadas na contracepção das puérperas assistidas pela ESF, porém são necessários novos estudos para avaliar a adesão aos métodos prescritos e disponíveis gratuitamente, a fim de controlar a fertilidade e saúde das puérperas.Descritores: Período Pós-Parto.

AXIOSPHERE OF THE MAGAZINE “RUSSKIY MIR.RU”
Authors: Nazarova Tat’yana Vladimirovna
Published: June 2018

The article demonstrates the possibilities of applying the method of the axiological analysis to identify the profile characteristics of the publication. The target goals of the magazine “Russkiy mir.ru”, the specificity of the content and genre model are determined. The author ascertains that the search for the ways to overcome the crisis of national identity goes in three directions: an image of the Russian land is being formed; the history of the country is recreated in documentary narratives about destinies of the people inhabiting it; the generalized ideal image of a person is modeled, in whose consciousness the values of the meaning of life, unity with the humanitarian goal, patriotism, altruism and creativity dominate.
RECONSTRUCTION OF THE WRITER’S BIOGRAPHY ON THE TEXT BASIS AS A SCIENTIFIC PROBLEM
Authors: Skleinis Galina Al'fredovna
Published: June 2018

The article deals with the possibilities of reconstructing a writer’s biography on the basis of literary texts, epistolary and memoir materials. This approach, little studied in the literary aspect, is one of the most topical and productive types of the study of the personality, world outlook and creativity of the artist of the word. A number of interrelated conditions are considered that allow reconstructing effectively a writer’s personality: the low degree of the study of life and creativity, the “non-peak” scale of a writer’s personality, intentional demonstration of views, genre specificity. As an illustration, the author offers specific examples from the creative work of writers of various levels, primarily V. V. Krestovsky and F. M. Dostoevsky.
TRADITIONS OF ORIENTAL LITERATURE IN THE WORKS OF N. SHELEBI
Authors: Sofronova Irina Vladimirovna
Published: June 2018

The article studies the traditions of oriental literature, typical of the creativity of the Chuvash poet N. I. Polorussov-Shelebi. The material for the analysis is the poet’s literary works written at the beginning of the ХХ century. In the course of the research, structural and typological methods are applied. The images of a bird and a snake used by the poet are an echo of Sumerian mythology. He could get acquainted with them through books published in the Tatar language. Poems about the history of the Volga Bulgaria, the history of the Huns are built by the stringing method. The poet uses consonant cognates in the depiction of the rich peaceful life of the Bulgarians, scenes of trading in the Tsivilsk Fair. Many publicistic poems are poetic retelling of events, description of environment. The reconstruction of the image of the Volga Bulgaria, its idealization, comparison of the modern reality with the glorious past of the Chuvash people is an echo of the influence of oriental literature.
I. S. TURGENEV’S NOVEL “THE NOBLE NEST” IN THE ASSESSMENTS OF THE TRANSLATOR ZHI LIANG
Authors: Chen Yanxiu
Published: June 2018

I. S. Turgenev’s novel “The Noble Nest” is one of the most beloved in China. During the twentieth century, it was translated dozens of times. One of the best contemporary translators of this novel is Zhi Liang, a graduate of the Faculty of Russian Language and Literature of Peking University, a professor at Shanghai Huadong Normal University and a deputy chairman of the comparativists’ association in Shanghai. The article focuses on the preface that Zhi Liang prefixed to his translation of “The Noble Nest”, because in it he expressed his attitude to Turgenev’s novel and proposed his understanding of its key images and ideas, somewhat different from the traditional interpretations of this text in China. Zhi Liang’s assessments are to some extent subjective, but they are sincere and indicate the translator’s personal involvement. His vision is free from stereotypes and important for the Chinese tradition of understanding Turgenev’s creative work.
NOMINAL RELATIVE «ПО ТИПУ» (“ACCORDING TO THE TYPE”): SEMANTIC AND SYNTAGMATIC FEATURES
Authors: Artemenko Maria Vladimirovna
Published: June 2018

The article describes the syntagmatic potential of the nominal relative ПО ТИПУ (“according to the type”) with a view to identify its semantic function. The author tries to discover to what extent the analyzed unit is transferred into the category of auxiliary words and proposes the criteria to differentiate the word combination ПО ТИПУ (“according to the type”) in auxiliary and non-auxiliary functions. Special attention is paid to analyzing the relative lexico-semantic environment. The author concludes that the word combination ПО ТИПУ in the structure of the construction gradually develops auxiliary features, which is manifested at lexical and syntactical levels.

Authors: Gorobets Viktor Ivanovich , Kul’sharipova Ravza Ekzamovna , Gorobets Elena Anatol’evna
Published: June 2018

The article is devoted to the features of the grammatical status and classification of reflexive pronouns in the modern Russian language and the representation of these features in the electronic thesaurus of morphological terms. 25 terms related to reflexive pronouns are identified (although traditionally academic literature focuses only on the reflexive pronoun «себя» / “oneself” and less on the reciprocal-reflexive pronoun «друг друга» / “each other”). The paper analyzes ambiguous interpretations, grammatical and semantic features of these terms.

This tendency is considered regarding the description of the personage’s inner emotional world because the writers of the so called courtly epoch focused just on the emotional sphere. The analysis allowed the author to identify the essential characteristics of German medieval literature. The paper focuses on the set of multi-level linguistic means representing the tendency for hyperbolization in German courtly novels.
NATIONAL AND CULTURAL PECULIARITIES OF PHRASEOLOGICAL UNITS WITH THE ORNITHONYM COMPONENT IN THE ENGLISH AND RUSSIAN LANGUAGES
Authors: Krepkogorskaya Evgeniya Vsevolodovna
Published: June 2018

The article deals with the national and cultural peculiarities of phraseological units with the ornithonym component. The phraseological composition of the language represents the historical and spiritual experience of the people. In the course of the comparative study of phraseological units, the understanding of national specificity leads to the understanding of the diverse aspects of lives of the people, who speak this language, the definition of common and distinctive features of the world perception. The study of the national and cultural peculiarities of phraseological units is of great importance for the research of the foreign language as it improves the motivation for mastering the language increasing aesthetic and emotional impact. Phraseological units are studied at three levels, at which their national and cultural specificity manifests itself. The absence of the phraseological unit similar in meaning in the native language of a person creates certain difficulties in understanding the speech addressed to him or the correct perception of literary works. Knowledge of the national specificity of phraseological units plays an important role in crosscultural communication, since it contributes to the adequate understanding of the meaning that is laid in the utterance.
