Published: November 2020

Among the animal data, we have biometric measures related to the development and production of goats. Thus, the objective of this study was to evaluate the correlation between live weight and thoracic perimeter in the caprine species, in order to obtain a barometric tape to estimate the live weight of the animal, without the use of the scale. Caprines from 10 to 42 kg live weight were used; males and females; pure Saanen race and Saanen-Boer crossbred. The thoracic perimeter of each animal was measured after weighing, in which it was measured at the external circumference of the thoracic cavity, just below the axillae, with steel cable to minimize possible errors from the elasticity of the tape measure, with the animal in the correct position of legs angulations. All parameters were recorded with the fasting animal for 12 h. Subsequently the live weight was estimated by regression equations with high correlation coefficients. The study showed a strong positive correlation between live weight (kg) of the animal and the thoracic perimeter (cm). The barometric tape for Saanen and Saanen x Boer crossbreed presented 97% efficacy for the estimation of the weight of Saanen and crossbreed. The thoracic perimeter provides a high efficiency in the estimation of the live weight of caprines and can be used as an alternative when scales are not available, being more appropriate the separation by race and sex before adjusting the equation to be calculated.

Published: November 2020

Matriconditioning is a technique that aims to standardize and accelerate the germination of seeds and the emergence of plantlets. The objective of the study is to evaluate the effect of that methodology under the physiological performance of amaranth seeds. The experiment used two lots of seeds at the Universidade Tecnológica Federal do Paraná (UTFPR), Campus Dois Vizinhos (Parana State). Plastic boxes of the Gerbox type were the matriconditioning environment, containing 55.5 g of sterile vermiculite moisturized with distilled water at 100% of the retention capacity. Plastic boxes were placed in a germination chamber at ten degrees Celcius. Four repetitions of 100 seeds had their weight measured at 0, 2, 4, 8, 16, and 32 h after the procedure started to obtain the curve of imbibition. The following tests were performed after each period: Germination test, first germination count; length and dry mass of plantlets; emergence speed index, and accumulated emergence tests. Amaranth seeds achieve phase II of germination around 8 h of imbibition by matriconditioning. The effect of matriconditioning in the physiological performance of amaranth seeds varies as a function of the used lot.

Published: November 2020

Biostimulating microorganisms have protector effect against pathogenic agents, affect the stand formation, promote plant growth, and increase yield of agricultural crops. Thus, the objective of this work was to evaluate the seed germination and seedling emergence of different common bean cultivars as a function of treatments with Bacillus subtilis BV02 and Trichoderma asperellum BV10. Germination tests in paper rolls and sand were conducted in a completely randomized design, with a 2×4 factorial arrangement consisted of two cultivars, namely Campos Gerais (CG) and Estilo (ES), and four microorganism treatments, namely B. subtilis BV02 (BS), T. asperellum BV10 (TA), B. subtilis BV02 + T. asperellum BV10 (BS+TA), and Control. The variables analyzed were: germination speed index (GSI), emergence speed index (ESI), germination percentage, emergence percentage, root length, seedling height, and root and shoot fresh and dry weights. The CG cultivar had higher GSI, ESI, root length, seedling height, shoot fresh weight, root fresh weight, and shoot dry weight than the ES cultivar in the paper roll and sand tests. The common bean seed inoculation with BS+TA increased seedling height, shoot fresh weight, shoot dry weight, and root length in the ES cultivar. The CG cultivar had higher GSI, ESI, root length, root fresh weight, and root and shoot dry weights than the ES cultivar. The treatment of seeds with BS+TA is recommended to improve the performance of common bean seedlings of the ES cultivar.

Published: November 2020

The production of seminal bamboo seedlings is considered not viable, being this the biggest limiting factor. The tissue culture and minicutting are efficient, but very costly techniques, which makes it necessary to search for alternative techniques, such as propagation through culm sections. In this context, the objective of this study was to evaluate the efficiency of three methods of vegetative propagation with segments of the culm of the species Bambusa vulgaris, B. variabilis, B. tuldoides and Dendrocalamus giganteus. The experiment was carried out in a randomized block design, factorial scheme of four (4) species (Bambusa vulgaris, B. variabilis, B. tuldoides and Dendrocalamus giganteus) and three (3) methods of preparing the propagule (a single node, binodal propagule, and binodal propagule + H 2 O), with four replicates and plots of five propagules. The propagules were deposited in shallow pits kept in field conditions. At 45 days, the percentage of shoots was measured and analyzes of variance and Tukey were performed at 5% error probability. For D. giganteus, none of the methods of preparing the propagules proved to be efficient for their propagation. The species B. vulgaris, B. variabilis and B. tuldoides showed higher percentages of sprouting. The method of preparing propagules with a single node was more efficient for B. variabilis, B. vulgaris and B. tuldoides.

Biofertilizers can also be used as plague and disease control agents. The commercial product Microgeo® is a biological biofertilizer rich in microorganisms. Few studies have been carried out to evaluate the interaction between biofertilizer and nematodes. The objective of this study was to evaluate the efficiency of the Microgeo® biological fertilizer to control the nematode Pratylenchus brachyurus in two sugarcane cultivars. The work was carried out in greenhouse conditions with a completely randomized experimental design (DIC), in a triple factorial scheme (2 x 2 x 4), being two types of sugar cane (CTC 04 and CTC 9003), two types of management of the biofertilizer (Management 1: application of the biofertilizer and inoculation of the nematode at 0 days after transplanting (DAT), management 2: application of the biofertilizer and inoculation of the nematode in the roots of the plant 30 days later) and four doses of the liquid biofertilizer Microgeo® (0 L ha‑1; 150 L ha-1; 300 L ha-1; 450 L ha-1), with four replications. 800 specimens of P. brachyurus were inoculated in each experimental plot. The results showed that cultivating CTC 9003 during the conduct of the experiment showed greater susceptibility to the nematode compared to cultivating CTC 04. The biofertilizer Microgeo® showed no curative or preventive effect on the control of the nematode under the conditions of the experiment.

Published: November 2020

The suitable management of nitrogen (N) fertilization can increase barley grain yield, since it is the nutrient required in greater quantity. In this sense, the source and timing of nitrogen application are relevant factors. The objective was to evaluate the effects of N sources and splitting on the performance of barley. The experiment was carried out under a clayey Cambisol (550 g kg-1), in Curitibanos, Santa Catarina. Factorial randomized blocks were used: three mineral sources of N: urea (45% N); urea with urease inhibitor-NBPT (45% of N) and nitrate (30% of N), associated with two nitrogen splitting fertilization: i) split of the rate of N in two seasons: beginning of tillering and full tillering and ii) single application at full tillering. 100 kg ha-1 of N were applied. There was no interaction between the factors and there was no effect of treatments for plant height, ear length, grains per ear, ears per m² and mass of a thousand grains. Yield was influenced by the N source, where nitrate exceeded the yield from amidic sources by 16%. The splitting of N in two times did not present advantages over the single application. Urea with NBPT was not viable in relation to readily soluble forms of N, with the highest yield obtained with a nitric source.

Published: November 2020

The adoption of different soil management techniques in coffee plants can alter the phytosociology of the weed community and, therefore, identifying the technique that most contributes to an integrated weed management is fundamental. In this context, the objective of this study was to evaluate the phytosociology of weeds in coffee plants under different soil management techniques. The land was planted in January 2016 with coffee seedlings of the species Coffea arabica L., cultivar Mundo Novo IAC 379-19. The design used was in randomized blocks, arranged in a 2 x 6 factorial scheme, with 3 replications. Two evaluations were carried out: in the rainy season and in the dry season, in 2017. The management techniques applied inter-rows were: i) control (spontaneous vegetation in the area); ii) management with Urochloa decumbens. On the coffee in-rows, the treatments were: iii) coffee husk; iv) organic compound; v) plant residues of U. decumbens; vi) plant residues of U. decumbens with coffee husk; vii) plant residues of U. decumbens with organic compound; viii) control (without coverage). For the evaluations, a square (0.25 m²) was randomly launched and the phytosociological indices were subsequently calculated. The species of the families Poaceae and Asteraceae were the most frequent in the area. The management with U. decumbens inter-rows and the crop residues deposited in the row associated with the coffee husk, or organic compound, decreases the amount and the diversity of weed species.

Published: November 2020

Silicon is a beneficial nutrient for the growth and production of many plant species, including tomatoes. The objective was to evaluate the influence of calcium silicate on the morphophysiological characteristics of tomatoes and the absorption of silicon, calcium, and magnesium. The experiment was conducted in a protected environment from August to December 2017, in a random block design, in a 2 x 5 factor scheme, with four repetitions. The first factor consisted of two hybrids (Ivety and Natalia) and the second factor by doses of calcium silicate (0, 150, 300, 450 and 600 kg ha-1). The fruits were evaluated for number of fruits per plant, longitudinal and transversal diameter, average fruit mass, commercial, non-commercial, and total productivity. The plants were evaluated for number of leaves, stem diameter, plant length, leaf area, membrane integrity damage, lignin content, stem and leaves dry mass, silicon accumulation and content, calcium, and magnesium contents in the leaves and in tomato fruits. The morphometric characteristics of Ivety and Natalia tomato hybrids were not altered by increasing doses of calcium silicate. The increased doses of calcium silicate influenced the non-commercial productivity of the tomato fruits, showing a reduction of this with the increased doses. Calcium silicate influenced differently in each hybrid, and it is worth noting that these results may vary in terms of genetic material and cultivation environment.

Published: November 2020

The search for natural wood preservatives is becoming increasingly evident due to industrial preservatives presenting several environmental restrictions, such as soil, water and ecosystems contamination. Therefore, the objective of the present study is to evaluate the antifungal activity of Cinnamomum zeylanicum bark natural extract subjected to rotting fungi. In order to obtain the aqueous extract, two methods were performed with different concentrations, 50 and 100 g L-1, using Pycnoporus sanguineus e Gloeophyllum trabeum, mycelium. In the first, we kept the C. Zeylanicum bark with distilled water for 1 h in water bath and, in the second, the same concentrations were used, however, this was kept in a recipient for 24 h. Then, the extract was subjected to sterilization along with the BDA medium in autoclave at 120ºC for 20 min, they were then put in petri dishes for later evaluation of the mycelium root growth compared with the control. The fungi Pycnoporus sanguineus presented higher fungal activity, obtaining total inhibition of all treatments and extract concentrations, however, for the fungi Gloeophyllum trabeum, the 100 g L-1 concentration warmed in water bath obtained a better result than the others. Therefore, it can be concluded that the Cinnamomum zeylanicum aqueous extract presented inhibitory potential. Considering this, we suggest that more studies with this thematic should be carried out, seeking to discover new alternatives for wood preservatives that are less damaging to the environment and to mankind.

Published: November 2020

Brazil is the largest producer of sugarcane crop in the world,but its production can be highly affected by the pest Sphenophorus levis. The entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana can be used for the control of this pest, but are not always effective in the field, lacking information on application methods, doses and formulations. We evaluate the efficacy of M. anisopliae IBCB 425 and B.bassiana IBCB 66 in controlling S. levis and other soil pests at sugarcane crop. The bioassay was conducted in a split plot design, where each of the 4 treatments were repeated 5 times and distributed over an area of 5.000 m2. The treatments for both fungi consisted of: Wettable powder (WP) formulation 225 g conidia ha-1, WP formulation 450 g conidia ha-1, granule (GR) formulation 10 Kg ha-1 and Control (no fungal application). WP fungi formulations were applied to the ratoon with a tractor using a ratoon cutter and an pesticide applicator. The GR fungi formulation was manually applied on the ratoons. The evaluations were performed after 21, 60 and 100 days of fungi application. B. Bassiana fungus reduced the pest population but did not differ from the control, however for M. Anisopliae fungus there were significant differences between treatments on damaged stems. The fungus M. anisopliae was effective in controlling S. levis larvae and adults in the field and WP formulation had faster action than the GR, the dose of 225 g conidia ha-1 was enought to reduce S. levis population.

Published: November 2020

The paper presents the research study of academic writing of Czech university students in an English Language Teacher Education study program. The authors apply an interdisciplinary approach integrating the perspectives of linguistics and language pedagogy in the evaluation of the design of the Academic Writing course and its impact on the development of students’ academic writing skills. Adopting a process genre approach (Badger, White, 2000) to writing instruction as a key design principle, our study combines the genre analysis framework (Swales, 1990) and the intercultural rhetoric perspective (Connor, 2004) to design an innovated academic writing course for graduate students focusing on developing critical thinking skills and context-aware writing. The course, informed by an analysis of the academic writing needs of the students, aimed at familiarizing them with the rhetorical structure of academic texts with a focus on the genre of the Master’s thesis and at introducing them to the academic writing conventions in the area of soft sciences. Piloted in 2019, the course was implemented as a blended course, where the contact sessions were complemented by online support in VLE Moodle. Apart from analyses of written texts, classroom writing, and homework tasks, it also included discourse editing tasks and peerreviewing with peer-reviewer feedback and teacher feedback. We believe that our research findings will shed light on the potential of academic writing courses based on the process-genre approach to contribute to the enhancement of the quality of English academic texts by non-native academic writers, and specifically Czech graduate students.

Published: November 2020

Subject. At present, diseases of the gastrointestinal tract, with a high frequency in children aged 9―14 years, are accompanied by lesions of the oral mucosa. These conditions are aggravated with orthodontic treatment. Therefore, the development of a scheme for the prevention of complications in children with gastrointestinal diseases undergoing orthodontic treatment is an urgent task of modern dentistry.

Purpose ― to consider the problem of the state of the oral cavity and the cytological characteristics of the mucous membrane in children with gastrointestinal diseases, physiological occlusion and malocclusion undergoing orthodontic treatment, to investigate the dynamics of inflammatory processes of the jaw mucosa under the bases of removable orthodontic appliances.

Methodology. The study involved 60 children aged 7―15 years. The cytomorphometric method was used.

Results. The results of the study showed the possibility of using the cytomorphometric method for diagnosing and evaluating the effectiveness of the use of various prevention programs and medicines during orthodontic treatment. Cytomorphometry revealed significant differences in the effectiveness of the proposed prophylaxis scheme in children, contributed to the improvement of cytogram parameters and normalization of the inflammatory-destructive index, however, complete recovery of all cytomorphological parameters in patients undergoing orthodontic treatment did not occur.

Conclusions. To improve the level of oral hygiene for children undergoing orthodontic treatment, it is necessary to use not only therapeutic and prophylactic toothpastes, but also an additional amount of prophylaxis. Children with gastrointestinal tract diseases and malocclusion who are undergoing orthodontic treatment are recommended to include Lizobact drugs in the periodontal disease prevention regimen, however, the use of these drugs alone is not enough to completely eliminate the inflammatory process.

Published: November 2020

Subject. In recent systematic reviews, the question of the clinical value of cytokines of the interleukin-1 (IL-1) family in chronic periodontitis (CP) has been discussed. Some authors consider them to be reliable biomarkers, while others believe that although they allow differentiating gingivitis and severe CP, the quantity and quality of published works require further research in this area.

The aim of the study was to evaluate the clinical value of the level of cytokines of the IL-1 family in chronic mild periodontitis.

Methodology. All study participants were divided into two groups: main and control. The main group included 45 patients with mild chronic periodontitis, the control group consisted of 32 practically healthy volunteers without periodontal pathology. The concentration of IL-1α and IL-1β, IL-18, IL-1RA (receptor antagonist) in the oral fluid was determined by the method of multiparameter fluorescence analysis with magnetic microspheres (хMAP-technology, Luminex).

Results. In the group of patients with periodontitis, there was an increase in the oral fluid levels of IL-1RA by 3.14 times (p = 0.01), IL-1α - by 2.3 (p = 0.02) in comparison with the control group. The integral characteristic of the clinical value of the parameters (AUC) is quite high for both indicators: IL-1RA ― 0.91 and IL-1α ― 0.94. The content of IL-1β and IL-18 did not change significantly.

Conclusions. The study found an increase in the concentration of salivary cytokines of the IL-1 family in CP. Clinical and diagnostic characteristics of such tests as the content of IL-1α and IL-1RA in the oral fluid make it possible to consider them as biomarkers of mild chronic periodontitis.

Based on the data of representative sociological research of inhabitants of the Tyva Republic conducted by researchers of Institute of sociology of FCTAS RAS in April 2019, the article reveals the features of income stratification of the population of the Republic in the context of employment and financial behavior. It is shown that the model of income strat-ifi cation of Tuva is shifted down, since the population of the Republic is dominated by groups with incomes, usually not exceeding 1.5 medians, who also have loans or credits. In General, this situation is partly replicated at the country level. Savings strategies are not widely popular among the population of the Republic. It is also noted that the presence of official employment among the majority of respondents, although it reduces the risk of falling into the group of low-income people, does not guarantee their socio-economic stability. At the same time, individuals ‘ subjective estimates of their income are concentrated in approximately the same range, corresponding to the median group. This, on the one hand, indicates absubjective desire for more prosperous groups in material terms, and on the other hand, confirms that the established way of life is perceived by most Tuvans as the most common in the region, allowing them to feel no worse than the rest. The results of the study also show that in order to ensure an appropriate standard of living, the population of the Republic often turns to mutual assistance resources. At the same time about half of households pay debts to credit and microfinance organizations.

Nowadays, students cannot be separated from social media. Every student can have many accounts of social media. Social media itself is one of the students' primary needs, but social media has a significant impact. The purpose of this study is that researchers want to see the positive and negative impacts of social media on the social interactions of its users. Researchers used a qualitative type with a purposive method. Researchers conducted interviews with fourteen students of the Faculty of Social and Political Sciences, Universitas Airlangga. This study indicates that students' social media has positive and negative impacts on students' social interactions with their environment. One of the positive effects of social media is that students get the latest information more easily. Meanwhile, one of the negative impacts is that students become addicted to using social media to not interact with their environment. So, social media positively and negatively influences student interactions at the Faculty of Social and Political Sciences, Universitas Airlangga.
The impact of the Mobile Legend game in creating virtual reality
Authors: Mawalia Khefti Al
Published: November 2020

Online games have been very popular nowadays, more than games played by children and teenagers 30 years ago. This study aims to explore technological developments that people are interested in, namely the phenomenon of the emergence of the online game Mobile Legend. Mobile Legend has succeeded in making Indonesians interested because of its avatar, message feature, and buying and selling of online characters in one application. The evolution of online games from PC to Smartphone makes it easier for gamers to play games anywhere and anytime. Not infrequently, they can spend up to 6 hours a day looking for internet network access. Researchers use determinism theory to answer this phenomenon. The method in this study uses a qualitative type with a virtual ethnographic method. In addition, this research collects data on using virtual tracing to record and documenting virtual activities, and interviews with seven informants of Mobile Legends' players. This research shows that when a person plays games, he can become more apathetic and minimize interaction and communication with the social environment around him. Technology like Mobile Legend has eroded the socio-cultural side and communication sensitivity of an individual in society. All users also become more active and narcissistic in creating multiple identities that exist in the virtual world. So this research shows that online games in creating virtual reality have both positive and negative impacts on the players.

Background: Handling COVID-19 (Corona Virus Disease-2019) in Indonesia was once trending on Twitter. The Indonesian government's handling evoked pros and cons in the community. Public opinions on Twitter can be used as a decision support system in making appropriate policies to evaluate government performance. A sentiment analysis method can be used to analyse public opinion on Twitter.Objective: This study aims to understand public opinion trends on COVID-19 in Indonesia both from a general perspective and an economic perspective.Methods: We used tweets from Twitterscraper library. Because they did not have a label, we provided labels using sentistrength_id and experts to be classified into positive, negative, and neutral sentiments. Then, we carried out a pre-processing to eliminate duplicate and irrelevant data. Next, we employed machine learning to predict the sentiments for new data. After that, the machine learning algorithms were evaluated using confusion matrix and K-fold cross-validation.Results: The SVM analysis on the sentiments on general aspects using two-classes dataset achieved the highest performance in average accuracy, precision, recall, and f-measure with the value of 82.00%, 82.24%, 82.01%, and 81.84%, respectively.Conclusion: From the economic perspective, people seemed to agree with the government’s policies in dealing with COVID-19; but people were not satisfied with the government performance in general. The SVM algorithm with the Normalized Poly Kernel can be used as an intelligent algorithm to predict sentiment on Twitter for new data quickly and accurately.

Background: Literature in the peer-to-peer accommodation has put a substantial focus on accommodation listings' price determinants. Developing prediction models related to the demand for accommodation listings is vital in revenue management because accurate price and demand forecasts will help determine the best revenue management responses.Objective: This study aims to develop prediction models to determine the booking likelihood of accommodation listings.Methods: Using an Airbnb dataset, we developed four machine learning models, namely Logistics Regression, Decision Tree, K-Nearest Neighbor (KNN), and Random Forest Classifiers. We assessed the models using the AUC-ROC score and the model development time by using the ten-fold three-way split and the ten-fold cross-validation procedures.Results: In terms of average AUC-ROC score, the Random Forest Classifiers outperformed other evaluated models. In three-ways split procedure, it had a 15.03% higher AUC-ROC score than Decision Tree, 2.93 % higher than KNN, and 2.38% higher than Logistics Regression. In the cross-validation procedure, it has a 26,99% higher AUC-ROC score than Decision Tree, 4.41 % higher than KNN, and 3.31% higher than Logistics Regression.  It should be noted that the Decision Tree model has the lowest AUC-ROC score, but it has the smallest model development time.Conclusion: The performance of random forest models in predicting booking likelihood of accommodation listings is the most superior. The model can be used by peer-to-peer accommodation owners to improve their revenue management responses.

Background: Recently, WhatsApp has become the world's most popular text and voice messaging application with 1.5 billion users. A lot of WhatsApp Application Programming Interface (API) has also been established to be connected to other applications. On the other hand, the development of natural language processing (NLP) for WhatsApp messages has snowballed. There are extensive studies on the dissemination information using WhatsApp but the study on NLP involving data from WhatsApp is lacking.Objective: This study aims to implement NLP in smart dissemination applications by using WhatsApp API.Methods: We build a framework that embeds an intelligent system based on the NLP in WhatsApp API to disseminate a dynamic message. Some of the sentences are used to evaluate the accuracy of this application.Results: Smart dissemination consists of dynamic filter and dynamic content. Dynamic filter was conducted by using the POS tagger and clause statement. Meanwhile, dynamic content was built by using the replace MySQL function. There are twofold limitation: the application could not transform a message that matches rule <3> with conjunction “dan”; has the same attribute before and after  tag; and the maximum of the logical operator is one type for coordinating conjunction (AND/OR) in one sentence.Conclusion: Our framework can be used for dynamic dissemination of messages using dynamic message content and dynamic message recipient with an accuracy of 95% from twenty sample messages.
Accessible Statistical Regression, Extrapolation and First-Principles Modelling of Nuclear Data for Spent Nuclear Fuel Composition and Decay Heat Calculations in Short-Term Storage and Recycling
Authors: Holdsworth Alistair , Sharrad Clint , George Kathryn , Adams Samuel
Published: November 2020

Computational methods are essential to support and advance nuclear technologies due to the hazards of handling and analysing highly radioactive materials such as spent nuclear fuel (SNF). However, many such methods, including those thatcan predict SNF compositions and decay heat parameters, require expensive, proprietary software, alongside significant programming experience and computational power for utilisation, severely limiting availability of data and hampering research throughput. Although some datasets are available, many are incomplete or only cover certain fuel systems for older reactor types. Research investigating new methods for SNF recycling, for example, requires compositional and decay heat data for fuel systems not covered by extant data, though analogous source data may be available. With this in mind, we have developed a simple, accessible, and flexible method for extrapolation of isotopic, elemental, and decayheat compositions for SNF at discharge and following decay storage before recycling, based on an extant dataset. This semi-empirical method uses physical and mathematical first principles and can be performed using software accessible to all researchers. This provides outputs accurate to within 1% of reference values interpolated within the range of available data for isotopic compositions, with sensible extrapolations at higher burnups beyond those reported, withoverall elemental outputs accurate to within 0.1%of expected totals. In this publication, we present the developmental methodology, some sample data, the present limitations, and options for future development and expansion of functionality.
Wave Patterns of Gravity-Capillary Waves from Moving Localized Sources
Authors: Gnevyshev Vladimir , Badulin Sergei
Published: November 2020

We study wave patterns of gravity-capillary waves from moving localized sources within the classic setup of the problem of ship wakes. The focus is made on the co-existence of two wave systems with opposite signatures of group velocity relative to the localized source. It leads to the problem of choice of signs for phase functions of the gravity (“slow”) and capillary (“fast”) branches of the dispersion relation: the question generally ignored when constructing phase patterns of the solutions. We detail characteristic angles of the wake patterns: (i) angle of demarcation of gravity and capillary waves – “the phase Mach” cone, (ii) angle of the minimal group velocity of gravity-capillary waves – “the group Mach” cone, (iii, iv) angles of cusps of isophases that appear after a threshold current speed. The outer cusp cone is naturally associated with the classic cone of Kelvin for pure gravity waves. The inner one results from the effect of capillarity and tends to the “group Mach” pattern at high speeds of current. Amplitudes of the wave patterns are estimated within the recently proposed approach of reference functions for the problem of propagation of packets of linear dispersive waves. The effect of shape is discussed for elliptic reference sources.

Published: November 2020

Retails and shopping centers have become essential to today’s lifestyle. Furthermore, as modern shopping venues, retail centers' social role contributes to its popularity and profitability. The social motive of customers for shopping is beyond acquiring their crucial purchases. These advantages favor retail centers and improve the level of social sustainability and its relevant concepts. Given that relatively little study has been studied on the impact of retail centers' social role as places for interactional and recreational activities on customers' behavior in these centers and its relation to social sustainability. Two hypotheses were raised that show the effect of time travel duration and shop variety on increasing the percentage of users who spend their leisure time and recreational activities in two analogous retail centers. The result of research regarding the first hypothesis reveals that there is an interaction between time travel duration and shoppers' motivation. Furthermore, the results revealed that half of both retail center goers who spend more than 10 minutes to arrive at the retail centers prefer to do leisure activities and browsing than shopping. Therefore, the majority of individuals are from further distances, indicating longer trips can be one of the factors for willing to spend more leisure time and recreational activities. The second hypothesis reveals that shop variety can be one of the main reasons for attracting users to spend their leisure time and browse in both retail centers. There is a significant correlation between shop variety and customers’ motivation.
Design of a Cyclone Separator Critical Diameter Model based on a Machine Learning and CFD
Authors: Park Donggeun , Go Jeung Sang
Published: November 2020

This paper deals with the characteristics of the cyclone separator from the Lagrangian perspective to design important dependent variables, develops a neural network model for predicting the separation performance parameter, and compares the predictive performance between the traditional surrogate model and the neural network model. In order to design the important parameters of the cyclone separator based on the particle separation theory, the force acting until the particles are separated was calculated using the Lagrangian-based CFD methodology. As a result, it was proved that the centrifugal force and drag acting on the critical diameter having a separation efficiency of 50% were similar, and the particle separation phenomenon in the cyclone occurred from the critical diameter, and it was set as an important dependent variable. For developing a critical diameter prediction model based on machine learning and multiple regression methods, Unsteady-RANS analyzes according to shape dimensions were performed. The input design variables for predicting the critical diameter were selected as four geometry parameters that affect the turbulent flow inside the cyclone. As a result of comparing the model prediction performances, the ML model showed the 32.5 % of improvement rate of R2 compared to the traditional MLR considering the nonlinear relationship between the cyclone design variable and the critical diameter. The proposed techniques have proven to be fast and practical tools for cyclone design.
