Published: July 2021

Nanofluids has broad applications such as emulsions, nuclear fuel slurries, molten plastics, extrusion of polymeric fluids, food stuffs, personal care products, shampoos, pharmaceutical industries, soaps, condensed milk, molten plastics. A nanofluid is a combination of a normal liquid component and tiny-solid particles, in which the nanomaterials are immersed in the liquid. The dispersion of solid particles into yet another host fluid will extremely increase the heat capacity of the nanoliquid, and an increase of heat efficiency can play a significant role in boosting the rate of heat transfer of the host liquid. The current article discloses the impact of Arrhenius activation energy in the bioconvective flow of Burger nanofluid by an inclined wall. The heat transfer mechanism of Burger nanofluid is analyzed through the nonlinear thermal radiation effect. The Brownian dispersion and thermophoresis diffusions effects are also scrutinized. A system of partial differential equations are converted into ordinary differential equation ODEs by using similarity transformation. The multi order ordinary differential equations are reduced to first order differential equations by applying well known shooting algorithm then numerical results of ordinary equations are computed with the help of bvp4c built-in function Matlab. Trends with significant parameters via the flow of fluid, thermal, and solutal fields of species and the area of microorganisms are controlled. The numerical results for the current analysis are seen in the tables. The temperature distribution increases by rising the temperature ratio parameter while diminishes for a higher magnitude of Prandtl number. Furthermore temperature-dependent heat source parameter increases the temperature of fluid. Concentration of nanoparticles is an decreasing function of Lewis number. The microorganisms profile decay by an augmentation in the approximation of both parameter Peclet number and bioconvection Lewis number.

Monitoring of QTc interval is mandated in different clinical conditions. Nevertheless, intra-subject variability of QTc intervals reduces the clinical utility of QTc monitoring strategies. Since this variability is partly related to QT heart rate correction, 10 different heart rate corrections (Bazett, Fridericia, Dmitrienko, Framingham, Schlamowitz, Hodges, Ashman, Rautaharju, Sarma, and Rabkin) were applied to 452,440 ECG measurements made in 539 healthy volunteers (259 females, mean age 33.3 ± 8.4 years). For each correction formula, the short term (5-min time-points) and long-term (day-time hours) variability of rate corrected QT values (QTc) was investigated together with the comparisons of the QTc values with individually corrected QTcI values obtained by subject-specific modelling of the QT/RR relationship and hysteresis. The results showed that (a) both in terms of short-term and long-term QTc variability, Bazett correction led to QTc values that were more variable than the results of other corrections (p < 0.00001 for all), (b) the QTc variability by Fridericia and Framingham corrections were not systematically different from each other but were lower than the results of other corrections (p-value between 0.033 and < 0.00001), and (c) on average, Bazett QTc values departed from QTcI intervals more than the QTc values of other corrections. The study concludes that (a) previous suggestions that Bazett correction should no longer be used in clinical practice are fully justified, (b) replacing Bazett correction with Fridericia and/or Framingham corrections would improve clinical QTc monitoring, (c) heart rate stability is needed for valid QTc assessment, and (d) development of further QTc corrections for day-to-day use is not warranted.

T-cells are a subtype of white blood cells circulating throughout the body, searching for infected and abnormal cells. They have multifaceted functions that include scanning for and directly killing cells infected with intracellular pathogens, eradicating abnormal cells, orchestrating immune response by activating and helping other immune cells, memorizing encountered pathogens, and providing long-lasting protection upon recurrent infections. However, T-cells are also involved in immune responses that result in organ transplant rejection, autoimmune diseases, and some allergic diseases. To support T-cell research, we developed the DES-Tcell knowledgebase (KB). This KB incorporates text- and data-mined information that can expedite retrieval and exploration of T-cell relevant information from the large volume of published T-cell-related research. This KB enables exploration of data through concepts from 15 topic-specific dictionaries, including immunology-related genes, mutations, pathogens, and pathways. We developed three case studies using DES-Tcell, one of which validates effective retrieval of known associations by DES-Tcell. The second and third case studies focuses on concepts that are common to Grave’s disease (GD) and Hashimoto’s thyroiditis (HT). Several reports have shown that up to 20% of GD patients treated with antithyroid medication develop HT, thus suggesting a possible conversion or shift from GD to HT disease. DES-Tcell found miR-4442 links to both GD and HT, and that miR-4442 possibly targets the autoimmune disease risk factor CD6, which provides potential new knowledge derived through the use of DES-Tcell. According to our understanding, DES-Tcell is the first KB dedicated to exploring T-cell-relevant information via literature-mining, data-mining, and topic-specific dictionaries.
Evolutionary loss of thermal acclimation accompanied by periodic monocarpic mass flowering in Strobilanthes flexicaulis

Published: July 2021

While life history, physiology and molecular phylogeny in plants have been widely studied, understanding how physiology changes with the evolution of life history change remains largely unknown. In two closely related understory Strobilanthes plants, the molecular phylogeny has previously shown that the monocarpic 6-year masting S. flexicaulis have evolved from a polycarpic perennial, represented by the basal clade S. tashiroi. The polycarpic S. tashiroi exhibited seasonal thermal acclimation with increased leaf respiratory and photosynthetic metabolism in winter, whereas the monocarpic S. flexicaulis showed no thermal acclimation. The monocarpic S. flexicaulis required rapid height growth after germination under high intraspecific competition, and the respiration and N allocation were biased toward nonphotosynthetic tissues. By contrast, in the long-lived polycarpic S. tashiroi, these allocations were biased toward photosynthetic tissues. The life-history differences between the monocarpic S. flexicaulis and the polycarpic S. tashiroi are represented by the “height growth” and “assimilation” paradigms, respectively, which are controlled by different patterns of respiration and nitrogen regulation in leaves. The obtained data indicate that the monocarpic S. flexicaulis with the evolutionary loss of thermal acclimation may exhibit increased vulnerability to global warming.

Published: July 2021

Humans have dyed textiles and leather, colored food, and paint body parts using natural dyes throughout history. Natural dyes have suffered drastically due to recent socioeconomic changes and replacement with synthetic dye in the textile industry. Hence, it is urgent to study indigenous dye plants and dyeing craft in local communities to protect these resources' potential ecological, economic, and cultural values. In 11 Monpa villages of Mêdog County, South-east Tibet, China, we conducted field research to record the indigenous method of cloth dyeing using madder dye. An aqueous extract of the root of Rubia wallichiana is a traditional madder dye. In this study, we used traditional dye and ethyl alcohol extract of the residue of aqueous extract. Two fabrics were dyed with the extractions in the presence of one of the metallic mordants or biomordants. Pigment compounds from aqueous extraction of madder and ethyl alcohol extraction of recycled madder were evaluated using Phytochemical, UV–visible spectroscopy, and FTIR test. We carried out One-way ANOVA and Duncan's new multiple range method to analyze different dying approaches and conditions. The dyed fabrics were evaluated by indicators of color strength and fastness, including washing, rubbing, and perspiration. The findings revealed the potentiality of biomordants to improve the dyeing properties of madder. The dyeing properties of recycled madder were marginally better than traditional madder. The results revealed the feasibility of enhancing the dyeing property and reuse of the residue from madder dyeing. The improved dyeing and reuse of residue can improve local ecological, economic benefits, and cultural heritage while applying research findings for the subsequent commercialization of plant dyes.

Published: July 2021

The positive surgical margin (PSM) and biochemical recurrence (BCR) are two main factors associated with poor oncotherapeutic outcomes after prostatectomy. This is an Asian population study based on a single-surgeon experience to deeply investigate the predictors for PSM and BCR. We retrospectively included 419 robot-assisted radical prostatectomy cases. The number of PSM cases was 126 (30.1%), stratified as 22 (12.2%) in stage T2 and 103 (43.6%) in stage T3. Preoperative prostate-specific antigen (PSA) > 10 ng/mL (p = 0.047; odds ratio [OR] 1.712), intraoperative blood loss > 200 mL (p = 0.006; OR 4.01), and postoperative pT3 stage (p < 0.001; OR 6.901) were three independent predictors for PSM while PSA > 10 ng/mL (p < 0.015; hazard ratio [HR] 1.8), pT3 stage (p = 0.012; HR 2.264), International Society of Urological Pathology (ISUP) grade > 3 (p = 0.02; HR 1.964), and PSM (p = 0.027; HR 1.725) were four significant predictors for BCR in multivariable analysis. PSMs occurred mostly in the posterolateral regions (73.8%) which were associated with nerve-sparing procedures (p = 0.012) while apical PSMs were correlated intraoperative bleeding (p < 0.001). A high ratio of pT3 stage after RARP in our Asian population-based might surpass the influence of PSM on BCR. PSM was less significant than PSA and ISUP grade for predicting PSA recurrence in pT3 disease. Among PSM cases, unifocal and multifocal positive margins had a similar ratio of the BCR rate (p = 0.172) but ISUP grade > 3 (p = 0.002; HR 2.689) was a significant BCR predictor. These results indicate that PSA and pathological status are key factors influencing PSM and BCR.

The influence of the climatic potential of Western Siberia on the ecological plasticity of spring barley varieties
Authors: Yakubyshina Lyudmila , Shakhova Olga
Published: July 2021

Modern technologies of cultivation of crops directly depend on climatic parameters: temperature, amount of precipitation and their distribution by months. Crop productivity can be controlled by studying and understanding the influence of the climatic potential of Western Siberia. This paper is devoted to its features. Analysis of the influence of abiotic factors on the yield of spring barley for the period 2014-2019 showed that: the sum of effective temperatures of 1500°C, necessary for the growth and development of plants, accumulates annually; the harvest is formed by atmospheric precipitation for five months (May-September), which is 60% of the average annual norm with fluctuations from year to year from 12.1 to 38.0% (303.6-373.7 mm); the hydrothermal coefficient for May-July has an average effect on the yield of the Abalak, Acha, Vorsinsky 2 varieties (the coefficient of variation of the yield is 11.9, 14.9 and 16.3%, respectively) and significant effect on the crops of the Chelyabinsky 99 variety (the coefficient of variation is 25.7%). The Abalak and Chelyabinsky 99 varieties turned out to be more responsive to changes in growing conditions, as evidenced by the values of the regression coefficient (bi) (1.04 and 1.48) exceeding unity. The Acha and Vorsinsky 2 varieties are characterized by a weak response to improved growing conditions.

Published: July 2021

The study was carried out to investigate effect of mineral (CAN) and organo-mineral (OMF) top-dress nitrogen fertilizers on physiological and morphological parameters in three barley cultivars. The study revealed significant differences in the reaction of the cultivars in magnitude and direction of the yield structure elements. CAN had smaller effect on the studied parameters than OMF. CAN had no effect on grain yield and straw mass. Only for the cv. Novichok, there was an increase in grain weight from the main ear (15%), the length of the main ear (15%), the 1000-grain weight (2.9%). OMF led to increase grain yield in the cv. Novichok (43%), Pamiaty Rodinoy (16%), and did not change in the cv. Rodnik Prikamya. Only the cv. Novichok has increased the grain mass from the main ear (17%). The length of the main ear increased in the cv. Novichok (13%), Pamiaty Rodinoy (11%) but decreased in the cv. Rodnik Prikamya (7.5%). The influence of OMF increased the 1000-grain weight in the cv. Novichok (4.9%) and Pamiaty Rodinoy (2.5%), but decreased in the cv. Rodnik Prikamya (1.5%). Statistically differences were revealed in reaction of pigment complexes of flag and second leaves in all cultivars.

Published: July 2021

This article presents the results of research on the evaluation of rooting performance in the growing media of Ficus species in the interior. In the propagation of Ficus species, the vegetative method was selected and experimental work was carried out in growing media of 4 species. Sand (control), soil, Indole Butyric Acid (IBA) (4,000 mg/l) was obtained as cultivation media. The room temperature at which the experiments were placed was monitored and controlled. During rooting of cuttings, the room temperature was maintained at 18–24 ° C. Humidity was maintained at 40-50%. Soil and sand moisture were maintained at 30-40 degrees depending on temperature (based on the readings of the soil moisture meter). Observations were made and recorded every 3–5 days to determine the vegetative rooting rate of the Ficus Benjamin plant. Taking into account the transpiration of the plant and the evaporation of water into the air, 3-5 ml of water was poured in 10-12 days. As a result of these observations, the timing of vegetative rooting and irrigation norms were determined. Rooted plants were planted in peat, soil, humus feed, coarse sand substrate in a 1:1:1:1 ratio. In selecting these plants, a number of important indicators such as their growth patterns, leaf shape, habitat, drought tolerance, shade tolerance, soil moisture and composition were analysed and conclusions were drawn based on the findings.

Fast and efficient collection, processing and storage of huge amounts of information has become the main condition for the successful functioning of modern organizations, institutions and enterprises. The increasing rates of informatization of society increase the importance of computer technology in management processes. Using the capabilities of modern computing technology to automate the information processing process allows you to increase labor productivity, improve the efficiency of working with documents and speed up the exchange of information. At present, the concept of local information processing has become widespread. This allows you to organize the division of labor of personnel and automate the performance of their functions. To implement this idea, it is necessary to create workplaces for each level of management and each subject area, including remote ones. In the information economy, the successful promotion of an organization in the market is impossible without presenting the results of assessing the expected efficiency of automation. Evaluation of the effectiveness of the use of automated “virtual” workplaces is an ambiguous and multi-criteria process. Due to the huge variety of enterprises and the conditions in which they operate, options for automating activities, it is impossible to define standards, benchmarks. Each organization solves this issue independently, comparing with analogs.
Culture as an environmental factor on the impact of intrapreneurship in engineering companies: Comparison of German and American engineering companies
Authors: Toksöz Seray
Published: July 2021

The main aim of this study was to explore the extent to which intrapreneurship is taking place in engineering companies in the US and Germany. To serve this purpose, a deductive approach was followed, and a mixed methodology was employed in order to measure the perceptions about the existence of intrapreneurship in each country and to develop an understanding what factors have an effect on the concept among the engineering companies’ employees. The data collection procedure included questionnaires which were carried out with the selected employees of the engineering companies. For the analysis of data obtained from the questionnaires, several statistical analyses were utilised, and SPSS software was used. To obtain the managements’ views on the issue, interviews were conducted. Interviews were analysed through using narrative method. According to results, extent of the intrapreneurship perception among the US employees is higher compared to employees from Germany. Managements in both countries accepts the importance of intrapreneurship for their organisations however, it seems like there is a problem in flowing down these views to employees since employees especially in Germany believes otherwise. In this context, three main factors were determined in this study which can be counted as important factors which hinders the level of intrapreneurship in the US and Germany. These factors are lack of top management support, lack of communication and lack of adequate reward scheme within the organisations. In this study the role of culture in determining intrapreneurship behaviour within the organisations was also determined. In this context, it is believed that due to cultural differences between the US and Germany, employees do not perform intrapreneurship behaviour in Germany.

The article is devoted to the cognitive emotiological concept of pride. The relevance of the study lies in the fact that the compilation of conceptual lexical “portraits” and their subsequent comparison in different languages will reveal the similarity and difference in the natural language metaphysics of the compared cultures. Developed new author’s technique of “lexical portraying” of the concept determines the novelty of the research. The linguistic material of the research was the data from the corpus dictionaries “British National Corpus (BNC)” and “Russian National Corpus (RNC)” which represent a collection of grammatically marked texts. The first part of the article highlights the relevance of the study, defines the term “emotiological concept”, as well as provides general and specific for this area of research discussion issues from the field of cultural and cognitive linguistics. The authors analyze the interpretation of the term “concept”, the scope and content of this meaning and the ways of its description. The second part of the article is devoted to the study of the cognitions of “a proud man” and “a prideful man”. The authors conclude that the actualization of emotional feelings occurs under the influence of both external (socially conditioned) and internal (psychological) factors – the “provocateurs”. The third part presents the results of the cognitive analysis of the concepts “pride” and “гордость”. To provide this the authors refer to the definition of the realeme (a unit of the given lexical system). The ontogeny of the characterological behavioral qualities of “a proud man” and “a prideful man” is traced, and the amount of semantic and pragmatic information is established. Based on the analysis of the empirical vocabulary data and the considered connotations of lexical units “pride” and “гордость”, the authors propose a new type of “lexical portraying” and provide in the article the sample of one for the concepts “pride” and “гордость”. The developed etymological entry of the concept indicates 1) the cognitive elements of the concept, 2) the socio-cultural elements of the concept, 3) the semantics of the concept and 4) the syntax of the concept. The article dwells on emphasizing the fact that it is the cognitive elements that are universal for both Russian and English, while sociocultural, semantic, and syntactic elements might not always coincide in different natural language metaphysics. In conclusion, the authors summarize the data of the study and outline the promising areas of work in the field of concept science and cognitive linguistics.

Authors: Poliakova Nataliia , Skuratov Igor , Panicheva Elena
Published: July 2021

Being an integral part of the life of society, business discourse is of particular interest to study from the standpoint of the emotional behavior of its participants. The spheres in which this type of communication is used are different. The manifestation and expression of emotions in business discourse is the speaker’s intention to influence the interlocutor in the right direction, to cause a certain emotional reaction from his side. This paper examines the emotional component of French business discourse as one of the foundations of its coherence. An attempt is made to comprehensively analyze business discourse from the point of view of the verbal expression of emotions and determine their role in the implementation of pragmatic attitudes characteristic of this type of discourse. At the same time, given the rapid, constant development of the journalistic style in the French language, the disclosure of this aspect is of undoubted interest from the point of view of enriching information about the French media and modern French in general.

Venerable monks were head educators in social life and example of healthy life by fasting and prohibiting meal after dusk. The five elements of human body and evolution three elements were continuously changed in order to adapt environmental and climate changes. Monks used to manage their diet by knowing accumulation, activation and pacification of elements and six seasons. They live long with clear minds free from senility, opaqueness, which directly related to their proper diet and intellectual exercises. Aging is not obsolescence but a normal phenomenon of healthy body. In theory of the traditional medicine, biological age of may be related to the percentage of wind, bile and phlegm. It is possible to prevent and heal diseases through proper use of diet by coordinating with body features, age requirements and seasonal differences. By combining theory of traditional medicine and right lifestyle, there are ways for creating new preventive treatment methods.

The environmental imperative in education has given rise to a number of approaches and models, including the model of inclusive education, which requires the unification of students with different educational needs and capabilities within one educational system. The heuristic potential of such studies is significant, although very little understood. The ecological approach to understanding inclusiveness has significant practical significance and value: the ecological imperative helps to identify and implement the most effective and productive ways of transforming existing problems, without sacrificing either the tasks of development and movement forward, or the tasks of preserving the existing ones. At each stage of education inclusion as an ecological imperative presupposes certain accents. In preschool education, inclusion is the creation of an environment in which children can become aware of the differences between each other, related to their individual characteristics. In school education, children and adolescents can realize and feel the differences in the forms and strategies for building interactions and relationships between people, as well as the existence of different strategies, forms and types of learning activity and learning relationships. In university education, young individual can sense the differences that exist in the forms and relationships of professional and career activity.
