Optimización del diseño de aulas: aprovechamiento de la luz natural para confort visual en Villa María, Argentina
Authors: Salomon David , Avalos-Ambroggio Sofia
Published: April 2023

The present work addresses the problem of natural lighting in educational buildings, focusing on the study of natural lighting strategies that contribute to reaching recommended levels of lighting comfort in classrooms, correct light distribution and glare reduction. In this framework, a building on the campus of the National University of Villa María, Córdoba, Argentina, was analyzed in which the behavior of natural lighting was evaluated using simulation models and in situ measurements. The work was complemented by evaluating the Daylight Glare Probability (DGP) index: verifying the occurrence of glare. The diagnosis showed excess lighting at points close to openings, insufficient lighting at points far from them, low levels of uniformity in the distribution of natural lighting and intolerable glare thresholds. Consequently, a new arrangement of the classroom was proposed, incorporating elements for the redirection of sunlight and its performance was verified. The results of the proposal showed important differences. A significant reduction in lighting levels was achieved, reaching levels of visual comfort for classrooms (300-500 average lux), improvements in the uniformity of natural light, with its consequent verification according to standards, and a significant reduction in glare levels due to penetration direct sun.
СТЫКОВЫЕ БОЛТОВЫЕ СОЕДИНЕНИЯ СТЕРЖНЕВЫХ ЭЛЕМЕНТОВ С КОСЫМИ ФЛАНЦАМИ И ИХ РАСЧЕТ
Authors: Марутян Александр , Абовян Аветик
Published: April 2023

Приведено новое техническое решение монтажных стыков металлических конструкций в виде болтовых соединений на косых фланцах, расположенных под углом 30 градусов относительно продольных осей стержневых элементов и снабженных опорными столиками. В таких стыках продольные усилия, приходящиеся на фланцы, раскладываются на нормальные и касательные (тангенциальные) составляющие. Нормальные составляющие передаются на болтовые крепления, а касательные – воспринимаются опорными столиками. При этом в косых фланцах болты нагружены в два раза меньше, чем в прямых. Стыковые соединения обладают необходимым и достаточным запасом несущей способности, обеспечивают уменьшение расхода конструкционного материала и являются равнопрочными со стыкуемыми стержневыми элементами. Предложена практическая методика расчета таких соединений, подтвержденная итогами пробной (контрольной) серии исследований опытных образцов.
HYDRODYNAMIC STABILITY OF SWIRLING FLOWS WITH AXIAL RECIRCULATION ZONES
Authors: Akhmetov Vadim
Published: April 2023

The problem of the motion of a viscous incompressible swirling flow in an axisymmetric channel has been numerically investigated. Various flow regimes have been obtained, including those with the formation of the axial recirculation zones. In the framework of linear theory, the stability of the obtained calculated flows with respect to non-axisymmetric perturbations is investigated on the assumption of local parallelism. The growth rates and phase velocities of unstable disturbances are calculated. In the presence of a reverse flow zone, the disturbances growth rates are increased significantly.
BULK THEORY ELASTICITY FINITE ELEMENT BASED ON PIECEWISE CONSTANT APPROXIMATIONS OF STRESSES
Authors: Tyukalov Yury
Published: April 2023

The solution of the volume theory elasticity problem was obtained on the basis of the additional energy functional and the possible displacements principle. On the basis of the possible displacements’ principle, equilibrium equations for grid nodes are compiled, which are added to the additional energy functional using Lagrange multipliers. Linear functions are taken as possible displacements. The volumetric finite element based on piecewise constant approximations of stresses is presented. The stress fields are continuous along finite element boundaries and discontinuous inside ones. The calculation results of a cantilever beam and a bending plate are presented. The obtained solutions are compared with the solutions by the finite element method in displacements. The proposed finite element makes it possible to obtain more accurate stress values.

Published: April 2023

The specifics of the technology for the production of block foam glass are presented, the results of experimental studies of the properties of the material are presented, a method for improving production based on mathematical modeling of heat transfer processes is proposed. It is shown that the processes of high-temperature processing of foam glass make a key contribution to the formation of a high-quality porous structure, therefore, this area of ​​research needs the development of adequate methods for calculating the main macrophysical parameters based on the theory of heat transfer. A technique for checking the adequacy of the mathematical model of heat transfer is presented using the example of spontaneous cooling of a foam glass block. The entire procedure for checking the adequacy of the mathematical model was carried out in three stages. At the first stage, the degree of validation of the model is assessed, functional dependencies with the results of an experimental study based on the Pearson determination coefficient. The main stage includes the evaluation of the confidence intervals of the experimental data and the discussion of the convergence of the results of the analytical calculation with the results of the experimental data. The final stage, at which a comprehensive assessment of the adequacy of the mathematical model is given, includes both the results of the preparatory and the main stages. The results of the study showed that it can be concluded that the calculated data have sufficient convergence with the experimental data and indicate the adequacy of the developed mathematical model of heat transfer.

ЧИСЛЕННАЯ РЕАЛИЗАЦИЯ ВЗАИМОДЕЙСТВИЯ ГРАВИТАЦИОННЫХ ВОЛН С ОГРАДИТЕЛЬНЫМИ СООРУЖЕНИЯМИ МОРСКОГО ПОРТА
Authors: Кантаржи Измаил , Гогин Александр
Published: April 2023

Работа посвящена методу численного моделирования взаимодействия морских ветровых волн с оградительными сооружениями морского порта. Представлена классификация существующих численных волновых моделей в зависимости от их точности и требованиям к вычислительной мощности компьютера. В статье основным исследуемым эффектом взаимодействия волн с гидротехническими сооружениями порта является дифракция волн на защищаемой акватории. Для ее консервативного исследования в работе используется тестовая задача – два сходящихся оградительных сооружения на плоском дне с варьированием шириной входного створа и периодом подходящих волн. Тестовая задача физически смоделирована в волновом бассейне, а также численно с помощью волновой модели Буссинеска, реализованной в ПК MIKE 21. В рамках настройки численной модели предложен и обоснован наиболее корректный способ воспроизведения оградительных сооружений на численной модели – с отказом от ограждающей поглощающие слои стенки со стороны входного створа и постепенным уменьшением коэффициентов поглощения к входному створу. В результате сравнения результатов численного и физического моделирования получено удовлетворительное совпадение с разбросом значений 10-15%. Это позволило сделать вывод о том, что предложенный способ реализации оградительных сооружений позволяет корректно рассчитать дифракцию волн на защищаемой акватории, а используемую волновую модель считать верифицированной результатами физических экспериментов.
Slavic-Turkic Comparisons in the Diachronic Aspect
Authors: Dmitryuk Natalya V. , Arynbayeva Rimma A. , Makhanova Zhanna K.
Published: April 2023

The article is devoted to a comparative study of the concept man in the linguistic consciousness of the Eastern Slavs (Russians, Ukrainians) and representatives of the Turkic culture (Kazakhs, Kyrgyz) in a diachronic aspect. The globalization processes of the beginning of the 21st century mark the era of “civilizational breakdown” which is characterized by a change in the usual foundations of life and by obvious transformations of society. Thus, it seems relevant and prognostically valuable to reveal the content of the conceptosphere man in the linguistic consciousness of the ethnic groups under consideration in different periods of their life. The aim of the study is to determine the vector of displacement (or stability) of the axiological component in the choice of assessments and worldview ideas about a man among the informants of different generations. As research material, there were used associative dictionaries compiled on the basis of associative experiments conducted in different periods (Soviet and modern). The associative lexicographic material is recognized as one of the most reliable ways to access a person’s linguistic consciousness, the latter being understood by us as knowledge about the world “externalized” by linguistic signs, and its projections in the mental apparatus of a person, i.e., images of consciousness. This associative method of language consciousness research makes it possible to explain the facts of functioning and transformation of consciousness revealed in psycholinguistic experiments through the connection of these facts with ethnocultural peculiarities of ideas about the world of people as members of certain ethnosocial groups, with their general / universal (basic), and ethnospecific (local) cultural values. The comparative analysis undertaken in the research showed that the process of global civilizational shifts brings afore the interest and desire of the ethnocultural community to search for traditional ethnocultural values that (along with basic universal human values) can unite and strengthen the vitality of the ethnos. The work is being carried out with the prospect of further studies of the linguistic consciousness of ethnic groups, of determining the elements of (in)stability, and identifying conflict zones in the linguistic and conceptual picture of the world of Slavic and Turkic ethnic groups.
Filmtext as a Product of Several Cultures: the Problem of Transferring Cultural Concepts (Based on Films about Mulan)
Authors: Korovina Svetlana G. , Shabelskaya Nika K.
Published: April 2023

The problem of cultural transformations or transference remains a relevant object of research in film discourse. Of particular interest is the study of the representation of cultural concepts in films. It is noted that the film text is a complex linguistic product that can undergo primary, secondary and more transformations through comprehension by representatives of different cultures. There are many recipients have an opportunity for seeing a product of mass culture, therefore filmtext can also generate cultural transfers. There is a special position in the scheme of cultural transfer in the filmtext is occupied by the translator in the status of an intermediary and interpreter of culturally significant components of the original, responsible for the availability and maximally equivalent perception of information. This article examines the stages of cultural transfer and their influence on the final filmtext for the Russian viewer (final recipient); a classification and comparison of linguistic and cultural concepts are carried out based on the material of the films “Mulan” produced by Walt Disney Pictures (2020) and “Hua Mulan” (花木兰) produced by Beijing Film Company (PRC, 2019). The authors came to conclusion that the linguistic and cultural concepts selected in the course of the study have undergone several stages of cultural transformations during the transfer, contain “imprints” of this culture and therefore may not be understood by the final recipient.
What’s In A Russian English Username? A Case Study of Social Media Accounts Names
Authors: Lebedeva Irina L.
Published: April 2023

The present paper examines social media account usernames of Russian speakers of English. It aims to classify over a hundred Russian English usernames (collected between 2016–2021) in terms of their structure, typical linguistic features as well as translingual and transcultural patterns that underpin their creation. This paper argues that Russian speakers of English consciously and / or subconsciously creating their usernames employ a number of translingual and transcultural strategies and practices that are aimed at retaining and transmitting Russian linguacultural identity within such global multicultural English-dominated domain as international social media. Apart from signalling Russian identity of their owners, the analyzed usernames demonstrate that Russian social media users being bilingual en masse (at least, at a graphic level), do draw on Russian English for communication within the landscape of this social media thus facilitating further formation of the social media Russian English.
The Concept “Soul” and its Translingual Background (a Close Reading of Mourner’s Kaddish and Aleinu Prayer)
Authors: Talalova Larissa N. , Ser Gregory
Published: April 2023

Aleinu, a prayer that initially left us with questions, contains interesting qualities. It comprises the text that has changed its tone over generations. Having become more peaceful and perhaps accepting, Aleinu has kept its power to bind Jewish people together as a reminder to praise God collectively. Co-existence of both particularistic and universalistic themes in such a short piece of liturgy is quite a powerful thing. While preserving the very kernel of Jewish theology (oneness of God and His connection with Jewish people) the text of Aleinu goes further and suggests a very brave idea which signifies an ability of all to understand universal ethics. The historic association of Aleinu with stoicism of Jewish people in the face of tragedy creates an additional dimension for understanding of the meaning of the prayer as a source of hope and comfort. When S. Sulzer created his light melody the most communities know today, he realized the re-assuring spiritual potential of Aleinu.
Polylingual Literary Text: Estrangement and Translation
Authors: Razumovskaya Veronica A.
Published: April 2023

The research is focused on a polylingual literary text and, above all, on its typological and functional parameters. The use of foreign language inclusions and insets creates the estranging effect (In V. Shklovsky’s understanding) and removes the automatism of the reader’s perception of the text information. Special attention is paid to the translation aspect of a polylingual text existence in the multicultural space of the modern world. The issues of the allocation of translation units, as well as the boundaries of translatability and the main reasons of polylingual creative works untranslatability are considered. The hypothesis is put forward that the preservation of the estranging effect resulting from the use of foreign language inclusions and insets in the original text suggests the use of a special estranging strategy by a translator, which, along with the well-known strategies of foreignization and domestication proposed by L. Venuti, can complement the paradigm of culturally-oriented strategies of literary translation.

Letters, Memory, Language: about Russian Transcultural Literature
Authors: Shafranskaya Eleonora F.
Published: April 2023

The author of the article focuses on the image of letters as a symbol of national historical memory — on the example of Sukhbat Aflatuni’s story “Clay letters, floating apples”, where the letters act not only in their direct meaning, they are the antithesis of the imposed culture, language, historical interpretations. The article substantiates the legitimacy of using the term “transcultural literature” instead of the common and illogical one — “Russian-language literature”, since in this type of creativity the image of a different ethnic picture of the world, other national images of the world is paramount. The novel “Hands-rivers” by the contemporary writer Liana Shahverdyan is analyzed precisely in the categories of transcultural literature: the novel highlights the key themes and problems associated with the restoration of ancestral memory of family and the Armenian people, who, like millions of Soviet citizens, were subjected to Stalinist repressions. The metaphor of the carpet weaving culture, the carpet, the images of the local fauna — birds and snakes became the key ones in the analysis of the plot of the novel “Hands-rivers”. The novel by Liana Shahverdyan, based on archival documents, fills in the lost page of the history of the ХХth century, thus fitting into the current archival vector of the contemporary literary process.

Authors: Vasilyeva Nadezhda M.
Published: April 2023

The aim of the study is to identify and typologize the violations of orthographic norms in the Yakut language in the materials of ulus (district) newspapers. In order to achieve this goal, the following tasks are envisaged: 1) selection of ulus (district) Yakut-language newspapers for monitoring; 2) orthographic review of newspaper materials; 3) evaluation of the frequency of use and forms of spelling (In Russian script / fonetized form) of borrowed words in ulus (district) newspapers; 4) analysis of typical violations of Yakut orthography rules in ulus (district) newspapers. The scientific novelty of the research lies in the fact that it describes typical violations and deviations from orthographic norms of the Yakut language in the materials of ulus (district) newspapers. Particular attention is paid to the spelling of words borrowed from the Russian language. During the analysis we have come to the conclusion that in ulus (district) newspapers the spelling in phonetic form of many widely used borrowed words, whose bases were previously transmitted in the media materials in their original form, has become firmly established.

Barreiras ou pontos de inspeção? Ideologias linguísticas sobre migração e o modelo de comunicação moderno-colonial
Authors: Plaza Pinto Joana , Krüger Dias Ana Luíza
Published: April 2023

Neste artigo, apresentamos uma perspectiva crítica sobre regimes metadiscursivos da “barreira linguística” em contextos de mobilidade, discutindo a persistência dos pressupostos de transparência e homogeneidade herdados da razão moderno-colonial sobre nossos modelos de língua e comunicação, em confronto com práticas linguísticas heterogêneas em nossa experiência etnográfica com estudantes migrantes numa universidade pública brasileira. O artigo está dividido em três seções. Inicialmente, discutimos os usos da expressão “barreira linguística” no debate acadêmico sobre línguas e migração, evidenciando sua posição metadiscursiva para justificar ou racionalizar “desentendimentos” ou “problemas de comunicação”. Em seguida, apresentamos como a noção de barreira é articulada enquanto elemento estruturante da comunicação no debate público sobre imigração no Brasil, em notícias e documentos governamentais. Em seguida, analisamos formas metapragmáticas que emergem em interações entre estudantes migrantes participantes da nossa experiência etnográfica, quando elas avaliam e enquadram situações que poderiam ser identificadas como “barreira linguística” nos termos pressupostos pelos debates. Os resultados indicam que formas metapragmáticas que poderiam ser identificadas como “barreira linguística” configuram-se muito mais como “pontos de inspeção linguística”, funcionando como “paradas” interacionais de “checagem”, em que elas e/ou as/os interlocutora/es fazem uso de algum tipo de desencontro do contato linguístico para realizar ações no mundo. Concluímos que as formas interacionais resistem na fronteira da violência do modelo de comunicação moderno, desafiando seus pressupostos, ao mesmo tempo em que são tensionadas pela noção de “barreira linguística” enquanto figuração da governança das línguas e das pessoas em deslocamento ao redor do globo.
Aporias da desigualdade: o por vir das políticas afirmativas
Authors: Moraes Marcelo José Derzi , Pinto Marinazia Cordeiro
Published: April 2023

A partir da discussão sobre Justiça e Direito trazida por Derrida em sua obra Força de Lei: o fundamento místico da autoridade, discorremos sobre as aporias com que convivemos na rotina do pré-vestibular PVC 21290, em relação à política afirmativa de reserva de vagas. Para tanto, trazemos uma reflexão sobre o espectro da colonialidade que hierarquiza as pessoas, dividindo-as entre as que devem ter acesso e as que não devem ter acesso a determinados espaços, incluindo nesses espaços as universidades públicas. Entretanto, entendendo que as políticas afirmativas são da ordem do Direito, portanto, da ordem do cálculo, acreditamos que elas precisam estar em um movimento contínuo de aprimoramento, movimento que nos impõe uma responsabilidade, um investimento radical em ações que visem alcançar a Justiça.

Authors: Rizkiatami Azura , Masnita Yolanda , Kurniawati Kurniawati
Published: April 2023

Objectives: The purpose of this paper is to examine factors influencing consumer green purchase behavior towards international and local sustainable and slow-fashion brands in Indonesia. The fashion industry contributes 10% of total carbon emissions globally. Indonesia itself is a country ranked second in contributing water pollutant damage caused by textile production. The growth of fast fashion trends threatens the environment and the planet. But, public awareness of sustainable and slow fashion is beginning to rise. This study aims to further analyze factors influencing green purchase behavior. The theory of planned behavior was developed to examine consumer sustainable consumption behavioral intention. Methodology: Online questionnaires were distributed to people who had already purchased one of the sustainable brands in Indonesia at least once in their life. 283 data were collected but only 240 of which were able to fulfill the criteria of the study. Data analysis used Smart PLS 3.2.8.Finding: Environmental knowledge, eco-label, environmental advertisement, and green trust positively influence green purchase behavior. Environmental advertisement positively influences environmental knowledge, and environmental knowledge and advertisement positively influence eco-label. Green trust is not a mediating influence between environmental knowledge and green purchase behavior.Conclusion: This study's finding is that consumer awareness and recognition of sustainable fashion adoption is rising. People are starting to worry about textile production and consumption that harm the environment.

Objectives: The objective of this research is to analyze the impact of individual factors, environmental factors, and entrepreneurial behavior on the performance of MSMEs post the height of the Covid-19 pandemic.Methodology: This study uses a quantitative approach and the data was obtained by a questionnaire with 170 respondents from Jakarta who run micro, small, and medium enterprise (MSME) and applies digitalization in their business process. Data were processed using the SEM-PLS program.Finding: The result shows that individual factors influence entrepreneurial behavior. In addition, environmental factors influence individual factors. However, individual factors don’t significantly influence firm performance. Meanwhile individual and environmental factor mediates entrepreneurial behavior’s positive influence on firm performance. Conclusion: This study concludes that many, not only internal but external factors play a key role in how certain MSMEs can cope and survive during the Covid-19 pandemic. This study also contributes to showcasing some of the responses to government involvement and digitalization coupled with the MSMEs’ entrepreneurial behavior that can influence their performances.
Store Layout and Purchase Intention: Unraveling a Complex Nexus on Indonesian Minimarket
Authors: Timotius Elkana , Putra R Dimas Widya
Published: April 2023

Objectives: The store layout in a minimarket is a strategy to encourage repeat purchases from customers. This study attempts to assess the layout design of the minimarket in Indonesia and comprehend its contribution to purchase intention.Methodology: This research observed two well-known minimarkets in Indonesia, namely Alfamart and Indomaret. A literature review associated with field findings was conducted to find their relationship to consumer purchase intention.Finding: Consumers' shopping behavior in minimarket retail stores in Indonesia does not show much difference from the behavior of consumers in other countries. Consumers will not linger in a store that is generally not too large. They come to minimarket retail stores not for "window shopping" but have planned beforehand on the products that they will buy.Conclusion: A grid design in the minimarket is effective to shape consumer behavior by directing their movement, shopping effectiveness, and control. However, it needs a product display management that arouses interest in buying that invokes the feeling of completion and diversity, but also does not look too full and messy.

Entre os bens culturais identificados no Inventário Nacional de Referências Culturais dos Quilombos de Oriximiná, as histórias contadas sobre visagens, bichos e encantados se destacam em função de sua riqueza linguística, eloquência performática e carga simbólica, constituindo um elemento identitário peculiar das 37 comunidades quilombolas desse município paraense. Por meio de conversas informais e entrevistas abertas realizadas com 130 indivíduos em cerca de dois meses de trabalho de campo, foram registradas aproximadamente 70 narrativas dessa natureza, que deram vazão a uma recorrente forma de expressão da cosmovisão local. Do acervo constituído, integralmente transpassado para o suporte textual, o relato sobre “a corrente que arrastava” é tomado, em sua forma escrita, como objeto deste trabalho. Registrado na Cachoeira Porteira, ele traduz – em poucas palavras dotadas de alto valor simbólico – múltiplos aspectos do histórico de ocupação negra na região. Aponta, portanto, incontestes referências do patrimônio cultural das comunidades quilombolas de Oriximiná.
MARIANA LUZ

Published: April 2023

O texto discute a obra Murmúrios (1960), da poeta maranhense negra Mariana Luz (1871- 1960), segunda mulher a adentrar na Academia Maranhense de Letras em 1949. Professora, poeta, artista plástica e teatróloga, Mariana Luz sofreu, assim como muitos artistas negros, um processo de invisibilidade de sua vida e obra. Aqui procuramos recuperar a trajetória da poeta e analisar sua produção lírica. A pesquisa, de cunho predominantemente bibliográfico, também se vale de análise documental baseada na pesquisa hemerográfica de textos jornalísticos. A leitura analítica-interpretativa do texto poético, além de explorar suas tendências estéticas, busca evidenciar as relações dessa produção com a atmosfera social e cultural daquele período finissecular, em especial nos poemas que abordam a melancolia e a figura feminina. Discutir a poesia de Mariana Luz é de fundamental importância tanto para a história da literatura brasileira, quanto para a reparação histórica de sua invisibilidade.
Evaluation of Left Ventricular Stiffness with Echocardiography
Authors: Wang Chuan , Zhang Nanjun , Zhang Linling , Tang Liting , Shao Shuran , Wang Qinhui , Zhao Li , Hua Yimin , Liu Xiaoliang , Zhou Kaiyu
Published: April 2023

Half of patients with heart failure are presented with preserved
ejection fraction (HFpEF). The pathophysiology of these patients is
complex but increased left ventricular (LV) stiffness is proved to play
a key role. However, the application of this parameter was limited since
its measurements requires invasive catheterization. With advances in
ultrasound technology, new advances have been achieved in the assessment
of LV chamber or myocardial stiffness using noninvasive
echocardiography. Therefore, this review was carried out to summarize
the pathophysiological mechanisms, correlations with invasive LV
stiffness constant, applications in different populations as well as the
limitations of echocardiography-derived indices for assessment of both
LV chamber and myocardial stiffness. LV chamber stiffness indices such
as E/e’/LVEDV, E/SRe/LVEDV, and DPVQ were derived on the basis of the
relationship between echocardiographic parameters of LVFP and LV size.
However, all these methods are surrogate and lumped measurements,
relying on E/e’ or E/SRe for evaluating LVFP. The limitations of E/e’ or
E/SRe in assessment of LVFP may contribute to the moderate correlation
between E/e’/LVEDV or E/SRe/LVEDV and LV stiffness constant. Even the
best validated measurement (DPVQ) is considered unreliable in the
individual patient. Compared to E/e’/LVEDV and E/SRe/LVEDV, I
and F may display better
performance in assessing LV chamber stiffness as evidenced by a higher
correlation with LV stiffness constant. However, only one study has been
conducted in the literature on the exploration and application of I
/I and F /F
, and its accuracy in assessing LV chamber stiffness
remains to be confirmed. In terms of echocardiographic indices for LV
myocardial stiffness evaluation, the parameters of EMI/DWS, iVP and SWI
were proposed. Despite alteration of DWS and its predictive value of
adverse outcomes in various populations have been widely validated, it
was found that DWS may be better considered as an overall marker of
cardiac function performance instead of pure myocardial stiffness. As
for the iVP and SWI, the validities of these two indices in assessing LV
myocardial stiffness have not been confirmed in invasive studies. More
echocardiographic indices with higher sensitivities and specificities
warrant to be further uncovered to evaluate LV stiffness.

Background. Two-dimensional speckle tracking evaluation
(2D-STE) is a useful tool to evaluate the complexity of atrial function
by the analysis of the different phases of atrial deformation and by the
combination with Doppler measurements of diastolic function. Aim
of the study. To evaluate the role of the left atrial (LA) strain
parameters to predict worsening chronic heart failure (CHF).
Methods. We enrolled outpatients affected by CHF referred to
our heart failure unit. Each patient underwent a medical visit, an
electrocardiogram (ECG), and an echocardiographic examination. LA
function was assessed by 2D-STE. The three phases of LA strain – i.e.
the reservoir (LAr), the conduit (LAcd), and the contraction (LAct) –
were evaluated. Moreover, the ratio between LAr and that of septal
(LAr/Ees), lateral (LAr/Eel), and septal-lateral (LAr/Eem) E/e’ were
evaluated. During follow-up, the worsening of heart failure was
evaluated. Results. Two hundred twenty-eight patients were
enrolled. During a mean follow-up of 14±7 months, 47 patients showed at
least one event related to heart failure worsening (40 hospitalisations,
5 heart transplantations, and 19 cardiovascular deaths). During
univariate Cox regression analysis, LAr, LAcd, LAct, LAr/Ees, LAr/Eel,
and LAr/Eem were all associated with events related to heart failure
worsening, but during multivariate regression analysis, only LAr (HR:
0.94; 95% CI: 0.91–0.98; p: 0.007), LAr/Ees (HR: 0.49; 95% CI:
0.30–0.78; p: 0.002), and LAr/Eem (HR: 0.65; 95% CI: 0.47–0.89; p:
0.008) remained significantly associated with the events. Finally,
LASr/Ee’s showed accuracy in predicting outcomes greater than LASr
(C-index 0.78 vs. 0.72, respectively). Conclusions. In CHF
patients, the measure of the LA reservoir by 2D-STE is independently
associated with heart failure worsening, but the accuracy in predicting
the events is even greater when the reservoir is combined with the
Doppler measures of diastolic function.

Today, with the rapidly developing technology, data volume and data
sharing are increasing day by day. Data mapping and reducing is very
important in the process of analyzing big data which in faster and more
effectively. In big data analysis, data mapping sequence and mining
works by using a specific algorithm the inputs and lists of values as
parameters. All values in the system entered for the intermediate
results which are converted and created. In the mapping process, the
data is subjected to fast sorting processes, taking into account the
area that occupied with the number of repetitions. Processing small
amounts of data has a cost-reducing effect on issues such as less time,
memory, process and disk consumption. In this study, data sorting and
data reduction operations were performed more effectively with the
proposed algorithm. The data prepared for data analysis with their
sortable features and then the process applied. Considering the data
size and value structures have been ensured that the reduction process
applied to each data reason of large amounts data processed at a much
higher cost. This process facilitated the selection of samples are also
easier. Software has been developed to realize with new subprogram which
was arranged by using of the Hadoop library. The value file transferred
and reduced to certain limits and then sequencing and mapping. Indexing
has been made in the mapping output. The mapping and reducing classes
working in parallel and an output file formed as a result of the
evaluation.

Introduction; MS is an inflammatory progressive disease with
destruction of myelin sheath of neurons and axons. Among environmental
risk factors HHV-6 might plays a role in MS. HHV-6 is a lymphotropic
virus causing neurological symptoms. HHV-6 may exist in the PBMCs and
CNS in a latent state. Materials and Methods; This case-control
study was conducted on 116 new cases of MS whom naive to MS drugs. The
control group consist 116 non-MS individuals whose gender, age and their
place of residency were matched with the cases. Ten ml of peripheral
blood was collected from each participant, their Sera and PBMCs were
separated and the DNA was extracted from them separately. After
Nested-PCR, the PCR products were sequenced. Statistical analysis of
data was performed by V.22 of SPSS software and chi-square and Fisher’s
exact tests and Odd‘s ratio were used. The P≤0.05 was considered as
statistically significant. Results; considering of existence of
HHV-6, there was a significant difference in PBMCs and Sera of case and
control group, but among male participants the difference between cases
and controls was not significant while this figure for female
participants was significant in PBMCs and Sera. Regarding age group,
only 21-25 and 31-35 groups were statistically significant. All positive
samples were variant 6B of HHV-6. Discussion; HHV-6 can be
considered as a MS risk factor mainly in female cases, especially in the
age group of 20-35. HHV-6 is in its active state (Sera) in these
patients.

Peas and vetches are the most important plant species for the production of
forages, where they can be used as hay, haylage or silage. Due to their
specific characteristics - tendency to lodging and high buffering capacity,
they are usually grown in a mixture with small grains as support crops to
prevent or reduce lodging, reduce buffering capacity, and at the same time
obtain biomass suitable for the ensiling process. In pure crops, peas are
most often used as green feeds or hay at the stage of first pod formation,
while the best quality of vetch dry matter has been achieved by using it at
the stage of full flowering or the beginning of first pod formation, when up
to 25% of crude protein is obtained in the biomass of pure culture. The
nutritive value of pure crops of peas, common vetch and oats, and their
mixtures is presented as a function of the structure of the mixtures and the
stage of use. Special attention is paid to the content of cell wall
components and the dry matter digestibility of these feeds. Because of all
of these mentioned above, it is particularly important to choose the right
harvesting time to balance the yield and nutritional value of feeds used in
bicrops.

The hygienic condition of dairy cows and their udders in 128 small household farms in different regions of Serbia, producing mostly milk, having 5-15 cows, a milk cooler and at least one milking machine, was evaluated by the following indicators: 1. general assessment of body cleanliness, 2. visual inspection of teats and udder base, and 3. maintenance of udder cleanliness, rated on a scale of 0 and 1 or 1 to 5. The samples were taken at each visit to the farm after cooling and tested for milk protein and fat content, somatic cell count (SCC) and the total number of microorganisms (TNM). The milk fat content was determined by the Gerber method, the protein content by the Kjeldahl method, the TNM according to the ISO 4833-1:2013 method and the SCC using Fossomatic TM. The IBM SPSS program was used for statistical data processing. Capacity, housing system, breed, milking system, number of cows, and capacity occupancy mostly had a very significant or significant impact on hygiene parameters, protein and fat content, SCC and TNM in milk. The hygiene parameters showed a continuous trend of improvement in relation to the visits. TNM mean scores increased after each visit, with significant differences between visits (F=9.63, P<0.0001). SCC scores varied very significantly between visits (F=5.17, P<0.0001). The number of visits tended to show a significant influence on the milk fat rate (F=2.221; P?0.1), but no influence on the milk protein rate (P=0.480; F=0.901).

Objective: To evaluate the performance of a real-time continuous glucose monitor (CGM) in individuals with diabetes on peritoneal dialysis (PD). 

Research Design and methods: Thirty type 2 diabetes participants on continuous ambulatory peritoneal dialysis (CAPD) wore a Guardian Sensor™ 3 on the upper arm paired with Guardian Connect™ for 14 days. We compared CGM readings against Yellow Springs Instrument (YSI) venous glucose during an 8-hour in-clinic session with glucose challenge. 

Results: The mean absolute relative difference (MARD) was 10.4% (95% confidence interval: 9.6, 11.7) from 941 CGM-YSI matched pairs; 81.3% of readings were within 15/15% of YSI values in the full glycemic range. Consensus error grid analysis showed 99.9% of sensor values in zones A and B. There were no correlations between pH, uremia, hydration status and MARD. 

Conclusion: We showed satisfactory performance of a real-time CGM sensor in  PD patients with diabetes, supporting future use to facilitate treatment decisions.
