Published: March 2019

Melanocortin-4 receptor (MC4R) gene has an important role in the regulation of feed intake and energy balance control. The objective of this study was to identify the single nucleotide polymorphisms (SNPs) of MC4R gene and their association with growth traits in Madura cattle. A total of 198 calves were used in this study.Forward primer: 5’-GTCGGGCGTCTTGTTCATC-3’and reverse primer: 5’-GCTTGTGTTTAGCATCGCGT-3’ were used to amplify approximately 493 bp of MC4R gene. The results showed that two SNPs, g.1133C>G and g.1108C>T were identified by direct sequencing. The PCR-RFLP method was performed to genotype all individuals studied based on SNP g.1133C>G, and its SNP was significantly associated with shoulder height (SH) at yearling age (P<0.05). Animals with GG genotype had a higher SH (110.35±6.40cm) than those with CC (102.00±8.00 cm) and CG genotype (105.96±6.23 cm). The SNP g.1133 C>G changed amino acid from valine to leucine. In conclusion, the SNP g.1133C>G of the MC4R gene may be used as a marker-assisted selection for SH trait in Madura cattle.
Computational Fluid Dynamics Studies of Gas-Solid Flows in a Horizontal Pipe, Subjected to an Adiabatic Wall, Using a Variable Gas Properties Eulerian Model
Authors: Patro Brundaban , Kumar K. Kiran , Krishna D. Jaya
Published: March 2019

In the present paper, a variable gas properties Eulerian model is employed to model the gas-solid heat transfer in a three-dimensional horizontal pipe, subjected to an adiabatic wall. The numerical model has been validated with the benchmark experimental data and other theoretical results available in the literature, and found satisfactory agreements. Moreover, the numerical heat transfer results considering the variable gas properties (i. e. density, dynamic viscosity, thermal conductivity, and specific heat) and constant gas properties are compared. It is noticed that the variable gas properties significantly affect the heat transfer, when compared to the constant gas properties. Therefore, the consideration of constant gas properties for the prediction of heat transfer may not be suitable in gas-solid flows, subjected to an adiabatic wall. Moreover, the temperature profiles, solid volume fraction profiles, and gas-solid Nusselt number are discussed. Finally, the pressure drop prediction with respect to the solid loading ratio is studied, and found that the pressure drop slightly decreases with increasing the solid loading ratio.

Authors: Zhang Pingsheng , Xin Yong , Ai Fanrong , Cao Chuanliang
Published: March 2019

The combination of double-fillers with synthetic polymers has been an attractive route for developing bone scaffolds. In this article, polycaprolactone (PCL) scaffolds were produced using a selective laser sintering (SLS) technique; multi-walled carbon nanotubes (MWCNTs) and eggshell (ES) were used as two fillers to improve their mechanical and osteogenic properties. The crystal phase, morphology, hydrophilicity, biocompatibility and mechanical properties of the composite scaffold were detected using X-ray diffraction, scanning electron microscope, water contact angle tester and in vitro cell test, respectively. Results show that ES improved the hydrophilicity and biocompatibility of the scaffolds obviously, whereas MWCNTs enhanced their compression and tensile strength. The PCL/ES/MWCNTs composited scaffold prepared by SLS possess excellent biocompatibility and mechanical strength, showing a potential application for bone repair.

Published: March 2019

Exploitation and utilization of mineral resources have played a vital role in China’s rapid economic developments. Although the history of mineral processing is quite long, technologies in this field have varied with the changes of market demands. This is particularly the case for minerals whose high-grade deposits are depleting. The aim of this review is to present our recent efforts on developing new routes for the utilization of low-grade minerals, such as iron ores and brine-containing lithium. The emphasis on the two minerals lies in the fact that iron plays a vital role in modern-day civilization and lithium is a key component in electric vehicles for transportation. Furthermore, the utilization of magnesium chloride reserves, one of the largest wastes in western China, as raw materials for fabrication of functional materials is also included in this review.
Index as scaffold to logical and final interpretants: Compulsive urges and modal submissions
Authors: West Donna E.
Published: March 2019

This inquiry capitalizes on the relational character of Peirce’s index. Its evolution from object finder in the physical world, to enhancer of communication between minds, to modal/perspectival coordinator is examined. Its relational character organizes events into episodes, and obviates perspectival alterations in dialogic reasoning. This shift demonstrates Peirce’s last word regarding Index: a sign intrinsically dialogic, whose interpretants increase levels of consciousness, and advance communicational interaction by commanding self/others to believe/act in novel ways.

Its power to coordinate specific, vivid images provides index with the means to suggest novel propositions, assertions, and arguments. Peirce memorializes this relational role by characterizing index as Dicisign, and afterward as Pheme (1904, CP 8.334–8.339; 1906, MS 295: 26; 1908, EP 2: 489–490). As truncated Argument, Index provides the catalyst for interpreters to determine the meaning of interpretants be they Energetic, Logical or Final. Its non-symbolic character provides interpreters the impetus to utilize inferencing powers to attach meanings, thus expanding kinds of interpretants. Index constitutes the most diverse semiotic tool for interpreters – it traces subtle deontic, epistemic, and logical shifts. In situating and resituating events in time, place, and participatedness, Index aptly measures actual and potential shifts in affect, attention, location, credibility, and the like.

Ultimately, index integrates the logical with the phenomenological and the empirical with the semiotic – when it deploys relational operators to trace event templates and to predict participant’s perspectives. As such, interpreters restructure thought and action and recommend sound courses of action for diverse event participants.
HSB-1 Inhibition and HSF-1 Overexpression Trigger Overlapping Transcriptional Changes To Promote Longevity in Caenorhabditis elegans
Authors: Sural Surojit , Lu Tzu-Chiao , Jung Seung Ah , Hsu Ao-Lin
Published: March 2019

Heat shock factor 1 (HSF-1) is a component of the heat shock response pathway that is induced by cytoplasmic proteotoxic stress. In addition to its role in stress response, HSF-1 also acts as a key regulator of the rate of organismal aging. Overexpression of HSF-1 promotes longevity in C. elegans via mechanisms that remain less understood. Moreover, genetic ablation of a negative regulator of HSF-1, termed as heat shock factor binding protein 1 (HSB-1), results in hsf-1-dependent life span extension in animals. Here we show that in the absence of HSB-1, HSF-1 acquires increased DNA binding activity to its genomic target sequence. Using RNA-Seq to compare the gene expression profiles of the hsb-1 mutant and hsf-1 overexpression strains, we found that while more than 1,500 transcripts show ≥1.5-fold upregulation due to HSF-1 overexpression, HSB-1 inhibition alters the expression of less than 500 genes in C. elegans. Roughly half of the differentially regulated transcripts in the hsb-1 mutant have altered expression also in hsf-1 overexpressing animals, with a strongly correlated fold-expression pattern between the two strains. In addition, genes that are upregulated via both HSB-1 inhibition and HSF-1 overexpression include numerous DAF-16 targets that have known functions in longevity regulation. This study identifies how HSB-1 acts as a specific regulator of the transactivation potential of HSF-1 in non-stressed conditions, thus providing a detailed understanding of the role of HSB-1/HSF-1 signaling pathway in transcriptional regulation and longevity in C. elegans.
Influence of new snow on growth and melting of sea ice
Authors: Zavyalov D. D. , Solomakha T. A.
Published: March 2019

Numerical experiments were carried out using the thermodynamic model with the aim to optimize choice of parameterization of the density of fresh snow, its albedo, and thermal conductivity coefficient in order to reproduce the seasonal evolution of ice thickness in the North-Eastern part of the Sea of Azov. The simulation results were compared with each other as well as with the observations obtained at the costal station of the Southern Scientific Center of the Russian Academy of Sciences in the Taganrog Bay. It is shown that small differences in the schemes of parameterization of physical and thermal properties of snow and ice cover may result in significant scatter in the simulation results. To assess the quality of the forecasting of the seasonal course of the ice thickness, the standard deviation of the calculated ice thickness from the average value for the period of measuring ice thickness, the standard deviation, the correlation coefficient, and the verification of the forecast were determined. Based on the analysis of these parameters, the optimal configuration of the snow layer parameters is proposed, which allows adequate reproducing of the seasonal thermal dynamics of the sea ice thickness. For the conditions of winter 2010/2011 the most close values of calculated ice thickness to results of the measurements in the North-Eastern part of the Taganrog Bay were obtained by determining the dependence of the density of fresh snow on the temperature in the near-surface layer of the atmosphere by the algorithm CLASS, albedo of the snow surface - by the scheme EHAM5, and the coefficient of thermal conductivity of snow – by the formulas of N.I. Osokin or M. Janson.

Published: March 2019

The Kolka Glacier, which rushed down the Genaldon valley on September 20, 2002 (North Ossetia), is now recovering after this catastrophe. One of the most important ways to predict a new disaster is to determine the rate of ice accumulation of the new glacier and to monitor the glacier volume regularly, since its trigger mechanisms have not yet been fully studied. Recent changes of the Kolka Glacier were investigated by means of ground stereoscopic photography. The field works were carried out in 2014, 2016 and 2017. Shooting was made manually with a digital camera Canon 5D Mark II (without using a tripod) at arbitrary points, the distance between which did not exceed 100 m. The reference points were placed on the elevated relief forms on the glacier surface and coordinated by a differential GNSS receiver in the "fast static" mode. Laboratory processing of the photos was performed using Agisoft Photoscan software in automatic mode, except for the procedure of identification of reference points on stereo images. The processing made possible to obtain digital models of the glacier surface in Geo-TIFF format, the vertical error of which amounted to 0.7 m, while the horizontal one – 2.3 m. In 2014–2017, the maximal increase in height of the surface (up to 30 m) was recorded in the low part of the glacier tongue that was the result of advancing of the Kolka front along the ice-free surface. Mean annual increase in the surface elevation was equal to 2.2 m/year. Lowering of the surface in some areas may be explained by the slowing-down of the glacier flow rate, which led to the appearance of thermokarst. The glacier volume increased by 7.4±0.7 million m3. As a result, the glacier tongue advanced by 50–70 m. Average over 2014–2017 increasing in the surface elevation (2.2 m/year) was slightly smaller than in 2004–2014 (3 m/year). Quick growth of the Kolka Gacier contrasts sharply with decreasing of volume of the representative Caucasus, Djankuat and Garabashi, over the same period.

Reproductive Attitudes of Young Rural Women in the Republic of Tatarstan
Authors: Shadrikov Alexander V.
Published: March 2019

Introduction. The modern rural society suffers a demographic crisis due to a drop in the birth rate and a decrease in the total fertility rate. Young women of reproductive age play an important role in increasing the number of births in rural areas. The objective of the paper is to study the reproductive intentions and preferences of young rural women in the Republic of Tatarstan as well as to identify the reasons for birth postponement and the degree of influence of the state support measures.

Materials and Methods. The results of a sociological survey conducted in the Republic of Tatarstan in 2018 were used as the materials for the study. Statistics were used for the calculation; the systematic and comparative methods of analysis were employed.

Results. The study has revealed the sustainable subjective preferences of young rural women in the Republic of Tatarstan to have two or more children. It has also confirmed the heterogeneity of the reproductive attitudes in the rural community and identified the rural women’s reasons for birth postponement. Assessment of certain reserves of increasing the birth rate has been made. State support measures affecting fertility rates have been evaluated.

Discussion and Conclusion. The increase in the birth rate in the Republic of Tatarstan largely depends on the quantitative and qualitative indicators such as the number of rural women of reproductive age as well as on the measures taken by the state to stimulate the birth rate and thereby increase the reproductive attitudes. The research materials will be useful for the heads of municipal districts, heads of governmental structures, scholars and helpful when devising federal and regional demographic and family development strategies as well as when implementing the Demography national project.

The present study provides scientific information for fatty acid composition of white brine cheese from cow milk, produced from all regions of Bulgaria, across seasons for the period 2012–2016. A total of 670 samples produced from different manufacturers and collected from supermarkets by Official control of Bulgarian Food Safety Agency (BFSA) were examined. Fatty acid composition was determined by gas chromatography. The milk fat purity of 18 samples was established through gas chromatographic analysis of triglycerides. Seasonal variations were observed in fatty acid composition of white brine cheese. The seasonal changes in the concentration of lauric, myristic, palmitic, stearic, oleic and α-linolenic acids have largely contributed to the variation of fatty acid composition
of cheese. Saturated fatty acids (SFAs) were in the range 68.39–71.53% of total FAs and the proportion of unsaturated fatty acids (UFA) was 28.44–31.61% of total FAs. Fourty-five out of examined samples have exhibited different fatty acid profile than that established in the present study for cow milk cheese. The determined SFAs were 44.7–57.5% and UFA varied from 42.5% to 55.3%. The fatty acids with short chain (C4:0 ÷ C10:0) were not detected or in traces, lauric and myristic acids were in small amounts, while palmitic and oleic acids predominated in the fatty acid composition of cheese analogues.

The study presents the tendencies in the preparation and
qualification of the modern Bulgarian teacher. The idea of a competent
approach in the process of professional training of the pedagogical
specialists in the higher school is revealed. An emphasis has been put on
synchronizing the training of Bulgarian teachers with common European
documents concerning the realization of the ideas for permanent training,
the formation of key competences, training aimed at realizing smart,
sustainable and inclusive growth. The regulations for acquiring the
professional qualification “teacher” after the democratic changes in
Bulgaria are analyzed. An analysis of the last ordinance regulating the
status and professional development of teachers, directors and other
pedagogical specialists is made.
Entertaining the Crowds: Early Ottoman Historiography between Orality and Bestseller
Authors: Gheorghe Adrian
Published: March 2019

The present paper deals with the issue of defining functional tools able to help modern historians understand the genesis and evolution of historiography in 14th-century Anatolia. It emphasises the indistinct lines between hagiographies and sagas and between leader-centred and popular texts, while making a strong case for the key role played by the necessity of creating entertainment. Having become bestsellers exponentially raised the chances of these creations to survive across centuries. Most of the texts we use today as historical sources were designed to entertain their consumers. Moralising or ideologically manipulating them came only in the second or third place.

The twenty-first century brought with it the proliferation of new media. We carry mobile devices and smartphones with us nearly everywhere we go. Constantly hooked up to the world by these tools, the bigger question is why we are sometimes not available. Our personal networks have partly migrated to online social networks, and new networks now penetrate our everyday lives in the digital sphere. In this online survey research, the authors searched for insights into how important smartphones and Facebook, the most popular social media site in Hungary, have become in people's lives. The kinds of attitudes that characterise the use of these tools were analysed, especially in the case of privacy and the use of personal data. The aim of this research — by establishing the actual situation — is to show how modern media, publicity, and privacy are linked, and how people reveal themselves by their constant media presence.
Evaluasi Penggunaan Ekstrak Lamun Sebagai Bahan Aktif Antifouling Terhadap Produsen Perairan
Authors: Puspitasari Rachma
Published: March 2019

Penggunaan TBT sebagai cat antifouling telah dilarang di dunia, oleh karena itu diperlukan bahan alternatif yang dapat menggantikannya. Fase awal dari fouling adalah pembentukan biofilm yang melibatkan bakteri. Cymodocea serrulata dan Syringodium isoetifolium diketahui berpotensi antibakteri terhadap Vibrio harveyii dan Bacillus subtilis. Sebelum dikembangkan lebih jauh sebagai bahan aktif cat antifouling, perlu diteliti keamanan dari lamun tersebut terhadap produsen primer perairan, salah satunya Chaetoceros graclis. Ekstrak kedua jenis lamun tersebut dipaparkan terhadap diatom selama 96 jam pada kondisi laboratorium dan dianalisis pengaruhnya terhadap pertumbuhan fitoplankton. Ternyata, S.isoetofolium menunjukkan penghambatan pertumbuhan diatom. Hasil dari uji anti bakteri dan bioassay menunjukkan bahwa lamun C. serrulata lebih potensial untuk dikembangkan sebagai bahan aktif cat antifouling daripada S. isoetifolium.

Authors: Ishlahiyah Hadiyatul , Sa'adah Sufi Ikrima
Published: March 2019

This article focuses on the description of magical realism in Leslye Walton’s debut novel The Strange and Beautiful Sorrows of Ava Lavender. This study applies Wendy B. Faris’ characteristic of magical realism in order to uncover the magical realism within the novel. The result of this study confirms that this novel portrays all of Faris’ characteristics of magical realism. They are: the irreducible elements represented by Ava’s wings, the phenomenal world seen through Ava’s normal life, the unsettling doubt coming from the doubts on Ava’s wings, the merging realms portrayed by the transformation and apparition, the disruptions of time and space through the existence of odd plant and seasons.

Background

Research on cancer survivorship associated with nasopharyngeal carcinoma (NPC) is rare. We aimed to elucidate the risk of ischemic stroke in 5-year survivors of NPC following radiotherapy (RT) or concurrent chemoradiation therapy (CCRT).

Subjects, Materials, and Methods

NPC survivors, defined as those who survived longer than 5 years after diagnosis, were identified and matched at a 1:5 ratio with normal controls from the Longitudinal Health Insurance Database 2005 of Taiwan. The stratified Cox regression models were used to access the risk of ischemic stroke, with adjustment for age, treatment modality, comorbidities, and socioeconomic characteristics.

Results

From 2000 to 2005, a total of 3,016 NPC survivors who had received RT (n = 959) or CCRT (n = 2,057) and 15,080 controls were matched for age, sex, income, and urbanization level. The risk of ischemic stroke was significantly higher in the NPC survivor cohort than in the control cohort. Stroke was positively related to death. Moreover, the age onset of stroke for NPC survivors was 10 years earlier than that for the general population.

Conclusion

Not only was the stroke risk in NPC survivors higher than that in the general population, but the onset age was also 10 years earlier. Future survivorship care should include ischemic stroke as a late complication, for its proper prevention and management.

Implications for Practice

Nasopharyngeal carcinoma (NPC) is endemic in Taiwan, and its 5-year survival is 65.2%. With the increased 5-year cancer survivors, survivorship has become an important issue. However, research on NPC survivorship is very rare. To the authors’ knowledge, this is the first population-based study on long-term NPC survivors. This study's results indicated that not only was the risk of ischemic stroke in NPC survivors at least triple that of the general population, but the onset age was also 10 years earlier. These results may provide solid evidence that survivorship care guidelines should include stroke as a late complication in 5-year NPC survivors, for its proper prevention and management.
Numerical investigation of reinforced-concrete beams with half-joints

Published: March 2019

The shape and dimensions of reinforced-concrete beams with half-joint or ‘dapped’ ends often represent a problem in structural design. If suitable geometry is not provided properly to the re-entrant corner, a diagonal tension crack may grow rapidly and failure will occur with little or no warning. In the study reported in this paper, two-dimensional finite-element analysis was adopted to investigate the effects of variation of some main parameters such as shear-span-to-depth ratio, the length ratio and the depth ratio. The analysis covered 29 specimens with half-joint ends, which had conventionally detailed reinforcement with an adequate development length of the longitudinal tension reinforcement beyond the re-entrant section. The structural behaviour of the specimens was compared and validated with previous experimental results from the literature. In addition, failure loads were compared with calculated values predicted by common codes and various equations. The results showed that shear capacity increases by reducing the nominal shear-span-to-depth ratio, reducing the length ratio or increasing the depth ratio. Moreover, the finite-element model was generally found to be in good agreement with previous test data.
Polskie głosy w dyskusji o niemieckiej przeszłości w dwóch inscenizacjach Kamienia Mariusa von Mayenburga
Authors: ŁAPICKA Kamila
Published: March 2019

Marius von Mayenburg (ur. 1972), jeden z najważniejszych niemieckich dramatopisarzy współczesnych, jest również reżyserem i tłumaczem współpracującym z berlińską sceną Schaubühne am Lehniner Platz. To artysta, który wierzy w historię i wierzy w postać. Jednym z owoców tej wiary jest Kamień, sztuka napisana w roku 2008. Artykuł proponuje analizę dwóch polskich inscenizacji Kamienia. Pierwsza została wystawiona w roku 2009 w Teatrze Wybrzeże w Gdańsku w reżyserii Adama Nalepy. Druga powstała pięć lat później jako spektakl dyplomowy studentów Łódzkiej Szkoły Filmowej. Na scenie Teatru Studyjnego przygotował ją Grzegorz Wiśniewski. Oba spektakle różnią się znacząco na wielu poziomach, począwszy od stopnia wierności wobec tekstu, poprzez wybór przestrzeni, na stylu aktorstwa skończywszy.
