Reverse time migration in tilted transversely isotropic media
Authors: Torres Razec Cezar Sampaio Pinto da Silva , Di Bartolo Leandro
Published: November 2020

ABSTRACT. Reverse time migration (RTM) is one of the most powerful methods used to generate images of the subsurface. The RTM was proposed in the early 1980s, but only recently it has been routinely used in exploratory projects involving complex geology – Brazilian pre-salt, for example. Because the method uses the two-way wave equation, RTM is able to correctly image any kind of geological environment (simple or complex), including those with anisotropy. On the other hand, RTM is computationally expensive and requires the use of computer clusters. This paper proposes to investigate the influence of anisotropy on seismic imaging through the application of RTM for tilted transversely isotropic (TTI) media in pre-stack synthetic data. This work presents in detail how to implement RTM for TTI media, addressing the main issues and specific details, e.g., the computational resources required. A couple of simple models results are presented, including the application to a BP TTI 2007 benchmark model.Keywords: finite differences, wave numerical modeling, seismic anisotropy. Migração reversa no tempo em meios transversalmente isotrópicos inclinadosRESUMO. A migração reversa no tempo (RTM) é um dos mais poderosos métodos utilizados para gerar imagens da subsuperfície. A RTM foi proposta no início da década de 80, mas apenas recentemente tem sido rotineiramente utilizada em projetos exploratórios envolvendo geologia complexa, em especial no pré-sal brasileiro. Por ser um método que utiliza a equação completa da onda, qualquer configuração do meio geológico pode ser corretamente tratada, em especial na presença de anisotropia. Por outro lado, a RTM é dispendiosa computacionalmente e requer o uso de clusters de computadores por parte da indústria. Este artigo apresenta em detalhes uma implementação da RTM para meios transversalmente isotrópicos inclinados (TTI), abordando as principais dificuldades na sua implementação, além dos recursos computacionais exigidos. O algoritmo desenvolvido é aplicado a casos simples e a um benchmark padrão, conhecido como BP TTI 2007.Palavras-chave: diferenças finitas; modelagem numérica de ondas; anisotropia sísmica.

OBJECTIVE

Text messaging interventions have high potential for scalability and for reductions in health disparities. However, more rigorous, long-term trials are needed. We examined the long-term efficacy and mechanisms of a tailored text messaging intervention.

RESEARCH DESIGN AND METHODS

Adults with type 2 diabetes participated in a parallel-groups, 15-month randomized controlled trial and were assigned to receive Rapid Education/Encouragement and Communications for Health (REACH) for 12 months or control. REACH included interactive texts and tailored texts addressing medication adherence and nontailored texts supporting other self-care behaviors. Outcomes included hemoglobin A1c (HbA1c), diabetes medication adherence, self-care, and self-efficacy.

RESULTS

Participants (N = 506) were approximately half racial/ethnic minorities, and half were underinsured, had annual household incomes <$35,000, and had a high school education or less; 11% were homeless. Average baseline HbA1c was 8.6% ± 1.8%; 70.0 ± 19.7 mmol/mol) with n = 219 having HbA1c ≥8.5% (69 mmol/mol). Half were prescribed insulin. Retention was over 90%. Median response rate to interactive texts was 91% (interquartile range 75%, 97%). The treatment effect on HbA1c at 6 months (−0.31%; 95% CI −0.61%, −0.02%) was greater among those with baseline HbA1c ≥8.5% (−0.74%; 95% CI −1.26%, −0.23%), and there was no evidence of effect modification by race/ethnicity or socioeconomic disadvantage. REACH improved medication adherence and diet through 12 months and self-efficacy through 6 months. Treatment effects were not significant for any outcome at 15 months. REACH reduced barriers to adherence, but barrier reduction did not mediate outcome improvements.

CONCLUSIONS

REACH engaged at-risk patients in diabetes self-management and improved short-term HbA1c. More than texts alone may be needed to sustain the effects.

Background: A gap exists when measuring skin routine care among females, generally in Saudi Arabia. Accordingly, measuring skincare routine practicing among female medical students will provide the community with the needed information that will help in enhancing skincare results and increase awareness of its importance.

Method: A cross-sectional study held at Qassim University. The data was collected through a self-administrated questionnaire. The data was entered and analyzed using Statistical Package for Social Science (SPSS) version 22.

Results: The total sample size reached 218 female medical students, of whom 99.1% were Saudi (216). Moreover, 55.5% have a combination skin type, while 16.1% have oily skin. The brand comes on the top of the factors determining the students' choices of skincare products while friend's recommendation came in second place.

There is an insignificant relationship between age and factors determining the students' decision to buy a skincare product and between skin type and factors. Forty four percent have reactions to some skin products, and there is an insignificant relationship between age and reactions to skin products and between skin type and reactions.

There is an insignificant relationship between age and skincare routines and between skin type and skincare routines. Unfortunately, 46.8% never consulted a dermatologist before choosing skin products.

Conclusion: The majority of skincare routines do not depend on medical consultancy. This indicates the need to increase the awareness of students to consult dermatologists, in order to avoid the high rate of reactions to some products.

ABSTRACTThis article generally aims to determine the ability to read with the ability to write, while specifically to get an idea of the relationship between reading and writing in writing an article. The ability to reading comprehension and write has a very close relationship when viewed from various aspect. This certainly happens because there is continuity between the two language skills. A writer will not be able to produce a good writing if unable and skilled in reading. Skillful in reading here means being able to understand the contents of the reading and know the meaning of the reading. Vice versa, if someone is skilled in reading then he will easily produce an article. Kata kunci: kemampuan, membaca, menulis

With wind energy extraction constantly increasing, the interest in small-scale urban wind turbines is also expanding. Given that these machines often work in adverse operating conditions (Earth’s boundary layer, vortex trails of surrounding objects, small and changeable wind speeds), additional elements that locally augment wind velocity and facilitate turbine start may be installed. This paper investigates possible benefits of adding an optimized flow concentrator to a vertical-axis wind turbine (VAWT) rotor. Three-dimensional, unsteady, turbulent, incompressible flow simulations of both isolated rotor consisting of three straight blades and a rotor with flow concentrator have been performed in ANSYS FLUENT by finite volume method for several different operational regimes. This type of flow simulations is challenging since flow angles are high, numerous flow phenomena and instabilities are present and the interaction between the blades and detached vortices can be significant. The rotational motion of the blades is solved by the unsteady Sliding Mesh (SM) approach. Flow field is modeled by Unsteady Reynolds Averaged Navier-Stokes (URANS) equations with k-ω SST turbulence model used for closure. Both quantitative and qualitative examinations of the obtained numerical results are presented. In particular, the two computed power coefficient curves are compared and the advantages of installing a flow concentrator are accentuated.

Due to the increasingly dynamic climate change and the increase in the number of people in cities, renewable energy sources (RES) are contributing to a more rational use of energy. Given the importance that the use of RES in housing directly brings in terms of financial savings and reduction of CO2 emissions, the paper examines the possibility of using RES in multi-family housing from the aspect of solar energy collection and conversion respectively implementation of photovoltaic panels and electricity generation. In multi-family housing, the problem of sustainability and implementation of RES is a complex task, primarily due to the existing ways of using space and ownership, which is multi-layered, but also the need for the active involvement of the entire housing community in deci-sion-making and initiatives. The research analyzes the advantages and disadvantages of installing solar panels on the rooftops and facades of buildings, and within the common open spaces in the block, by installing solar lamps, solar power for electric vehicles, solar chargers, etc. The examina-tion of the possibilities for using solar energy was conducted on the example of the residential Block 29 in New Belgrade, using urban analysis supported by appropriate data on solar radiation for the analyzed area and Skelion software for a numerical and graphical illustration of the amount of ener-gy that can be obtained by installing photovoltaic solar panels. The paper considers two different scenarios: when panels are installed on the roofs of buildings and when they are installed in open spaces, analyzing the potential of each and the prerequisites for their implementation in practice. The results aim to compare the quantities of electricity obtained by calculation for two different scenarios.

The main goal of the study was to determine parameters for the production of the micro-sized silver powder applicable to the pastes that are in use in solar cell production and maintenance. In all experiments, silver nitrate solution and ascorbic acid were used, as a silver source and reducing agent, respectively. Polyvinylpyrrolidone and gelatine were used as dispersants. The dispersant in this system acts as a protective agent in a way that prevents agglomeration and aggregation processes. The influence of used agents was different, and one of the aims in the research was to determine the pros and cons of them. The optimal parameters of the synthesis were the solution temperature of 45 °C, pH=7, and concentrations of silver and ascorbic acid of 45 g/l and 30 g/l, respectively. Although PVP has proved to be a suitable protecting agent for the goals of the study, the best results were obtained with the use of gelatine as a dispersant in the concentration ratio against the silver ions of 2.5 wt. %.

Due to the Portland cement chemical reaction, which always takes place in a hardening concrete, a certain amount of heat is released. This heat should be quantified, as it can harm or aid the concrete itself, depending on the concrete components, structure element, ambient and building site conditions. There are number of possible setups for the monitoring of heat of hydration, two of which have been applied in the case presented in this paper. Four concretes were monitored with the use of the two stated techniques for 24 hours. First technique used is thermo-vision camera which monitored the surface, and the second is thermosensor - used for monitoring of interior of fresh concrete hardening mass. The potential of the applied setup lays in the ease of installation, low price, and possibilities of mass application, which could substantially aid the monitoring and prevent concrete failure.

The present study was conducted to evaluate the efficacy of different natural antimicrobials agents (KMnO4 and Turmeric) in comparison with conventional antibiotics against the bacterial load and in relation to the quality of boar semen in Modena extender for up to 120 hours of preservation at 15 °C. A total of 56 ejaculates, 14 from each of four Hampshire crossbred boars maintained within the ICAR-AICRP on Pigs, in Guwahati, Assam, India, were utilized in the study. Thirty-two ejaculates, 8 from each of four boars were used to study the effect of antimicrobial agents on semen quality during preservation at 15 °C in Modena extender. A total of 9 different bacterial types were identified from 46 bacterial isolates, obtained from 24 fresh semen samples viz. Staphylococcus aureus (24%), E. coli (22%), Bacillus spp. (13%), Citrobacter spp. (9%), Pseudomonas spp. (9%), Staphylococcus epidermidis (9%), Klebsiella spp. (6%), Streptococcus spp. (6%) and Proteus spp. (2%). The overall sensitivity of the recovered isolates to Gentamicin, Ampicillin, Enrofloxacin, Cloxacillin, Streptomycin, Penicillin, Amoxycilln, Ofloxacin and Tetracyclin were 89, 39, 37, 48, 74, 52, 56, 76 and 63% respectively. The mean sperm motility, intact acrosome, HOST-reacted spermatozoa and bacterial load differed significantly (P˂0.01) between antimicrobial agents (Gentamicin, KMnO4 and Turmeric) and preservation periods (0, 48, 72, 96 and 120 hours). Sperm quality based on Gentamicin was found to be best, followed by Turmeric and KMnO4 during preservation at 15 °C. The conception rate for the semen preserved for 0, 24, 48, 72, 96 and 120 hours of preservation was 83.33, 80.00, 75.00, 66.66, 66.66 and 50.00% respectively. In the present study, the preserved semen with ascending bacterial load containing Gentamicin did not affect the conception rate.
A cross-sectional analysis of alcohol consumption, sex, and the odds of Alzheimer's disease and other dementias in the community-dwelling Canadian population
Authors:   , Tippett Jennifer
Published: November 2020

Background: The prevalence of Alzheimer’s disease (AD) and other dementias is perpetually increasing in Canada and worldwide with the aging baby boomer population. It is, therefore, important to identify risk factors for these major neurocognitive disorders, such as alcohol consumption, to mitigate the future burden on caregivers and the economy. The purpose of this study was to replicate previous research regarding the dose-response relationship between alcohol consumption and the odds of currently having AD or another dementia. The possibility of a sex effect moderating this relationship was also explored. Participants: Data were obtained for respondents to the combined 2015/16 cycles of the Canadian Community Health Survey who were aged 41 years or older at the time of the survey’s conduction (nweighted = 16,715,618). Methods: Logistic regression was used to crossectionally assess the relationship between various time- and frequency-related alcohol consumption exposures to outcome dementia status, while controlling for a number of demographic and risk factor variables. Results: A sex effect was identified for drinking at an average frequency of four to six times per week over the past year (p = 0.019, 95% CI: 0.03, 0.73) where women (ORw = 0.13) were more protected against currently having AD or dementia than men (ORm = 0.89) when compared to alcohol abstainers. Binge drinking two to three times per month (OR = 0.19, p = 0.015, 95% CI: 0.05, 0.73) and more than once per week over the past year (OR = 0.16, p = 0.007, 95% CI: 0.04, 0.61) significantly lessened the odds of currently having AD or dementia when compared against alcohol abstainers. A sex effect was present for those who were classified as very heavy drinkers (♂: 6+ drinks/day, ♀: 4+ drinks/day) over the past week (p = 0.018, 95% CI: 1.14, 39.41) where alcohol was protective against currently having AD or dementia in men (ORm = 0.29) and alcohol was a risk factor for currently having AD or dementia in women (ORw = 2.15) when both were referenced with alcohol abstainers. Conclusions: With the exception of very heavy drinker women, drinking alcohol was associated with a reduced likelihood of currently having AD or dementia and sex effects were identified for drinking at a moderate frequency over the past year and very heavy drinkers. However, these results should be interpreted with caution due to the possibility of selection, sparse data, and abstainer biases as well as misclassification error. The primary implication of this research is to inform future studies that a more thorough exploration of a sex effect influencing the relationship between alcohol consumption and having AD or dementia is warranted.
A holistic approach to capacity building: For professionals working with indigenous communities
Authors:   , Parisian Jennifer
Published: November 2020

The history of Education in Canada has been systemically and generational destructive to Aboriginal people and culture. This history of destruction has caused systemic racism throughout our school systems resulting in lower graduation rates and a lack of equity in achievement within education resulting in gaps in social-economic disparity for Aboriginal People in Canada (Archibald & Hare, 2017). This research project aims to address a gap in the education of educators in regard to closing the gap and working together for reconciliation. This project provides a framework for a holistic understanding of how to approach working within First Nations communities within the education system or across systems. The result of this project is a guidebook and PowerPoint presentation for professional development. The project provides educational professionals with some tools and knowledge to improve inclusive and culturally sensitive practice. The project delivers a common goal framework conceptualized by the researcher and adapted from a generalized, personal, and interpretative understanding of the Aboriginal Medicine Wheel. The four-part conceptual framework includes leadership, holistic approach, capacity building, and ethical considerations with the common goal in the center. The project brings together the concepts important to achieving the common goal of improving professional capacity when working with Aboriginal People and First Nations communities.
Barriers and facilitators to medical assistance in dying (MAID) discussions in primary care
Authors:   , Young Daphne
Published: November 2020

In Canada, medical assistance in dying (MAiD) is an end of life intervention intended to offer increased control to Canadians within the dying process (Brassfield & Buchbinder, 2020). Despite the legalization of MAiD in 2016 and developments in MAiD research, many primary care providers (PCPs) reported feeling reluctant to discuss MAiD with their patients (Otte, Jung, Elger, & Bally, 2017). In Canada, PCPs are typically medical doctors (MDs) or nurse practitioners (NPs) who care for patients in outpatient, non-acute care settings (Statistics Canada, 2019). As limited research has been synthesized on barriers and facilitators of MAiD discussions within the Canadian primary care context, the purpose of this integrative literature review (ILR) was to assess what factors promoted and prevented PCPs from discussing MAiD with their patients. After identifying a research question and related keywords, six databases were searched to identify relevant studies. The initial search yielded 1,874 results, which underwent inclusion and exclusion criteria and resulted in 12 references being included in the review. After collating the data, evaluating it, and summarizing the results, facilitators and barriers that affected the discussion of MAiD between PCPs and patients were divided into intrinsic and interpersonal factors. Intrinsic factors included PCP emotions, values, beliefs, education, and training, while interpersonal factors included communication, relationship, and administrative burdens (Brooks, 2019; Brassfield & Buchbinder, 2020; Selby & Bean, 2019; Kelly & Varghese, 2006; Pasman, Willems, & Onwuteaka-Philipsen, 2013; Hagens, Onwuteaka-Philipsen, & Pasman, 2017). Based on the findings of this review, strategies to promote MAiD discussions between PCPs and patients were outlined. Recommendations included identifying and addressing values, beliefs, and emotions; developing communication skills and strategies; promoting patientii provider relationships; and mitigating administrative burdens (Kelly & Varghese, 2006; Selby & Bean, 2019; Pasman et al., 2013; Brooks, 2019). As MAiD-related research in Canada progresses through its pioneering phase, future research has been suggested to support the development of communication guides specific to MAiD as well as the evaluation of PCP approaches to MAiD discussions within the Canadian primary care setting (Selby & Bean, 2019; Brooks, 2019).
Research of approaches and methods of applying artificial intelligence and machine learning in socio-economic processes
Authors: Sakhanevich Darya Yu.
Published: November 2020

One of the problems hindering the development of the socio-economic sphere in the innovative direction is the lack of structuring of approaches and methods used in machine learning as part of the introduction of artificial intelligence (AI) in socio-economic processes. The same problem hinders the growth of the pace of innovative development and, as a result, the improvement of the scientific and technical level of the country. The article classifies and systematizes aspects of machine learning, focuses on the need to accelerate the construction and implementation of algorithms as the basis of AI for increasing the efficiency of managing socio-economic processes. To achieve this goal, the following results are presented: analysis of the concepts of machine learning and AI, study of analytical materials regarding approaches and methods to the introduction of artificial intelligence and prospects for its application in socio-economic processes. There were systematized approaches to machine learning introduction to artificial intelligence depending on the historical period, the implementation of AI, and another, and methods according to the method of machine learning, predictive model data for creating AI algorithms (e.g., probabilistic), and the idea or the nature of the research that uses this technology (assessment and collection of statistical indicators, analysis). The study of the material related to machine learning and AI construction allowed us to draw the following conclusions. The theoretical foundation in the form of mathematical and statistical methods as the basis for building algorithms for creating AI in the framework of machine learning is a necessary part of the process of teaching computers human qualities. However, information about machine learning methods and approaches is mostly scattered, and it is necessary to form a unified methodological base in order to simplify the stage of searching for the right method of creating AI to solve any social, economic or other problem.

La idea de revolución en la Pedagogía del Oprimido
Authors: Fernández Mouján Inés
Published: November 2020

Escribo estas líneas atravesada por la tristeza de momentos difíciles que nos impone el orden neoliberal/necrófilo, pero con la alegría que me provoca escribir sobre Pedagogía del Oprimido. Lo hago a partir de una lectura comprometida y rigurosa de la obra. Elijo analizar la idea de “revolución” considerando dos versiones de la obra: Pedagogia do Oprimido (o manuscrito), 2013 y Pedagogía del Oprimido, 1971. Focalizo en su contexto de producción y en la racionalidad revolucionaria presente en el ensayo a partir de: “Primeras Palabras”, “Capítulo 1” y el “Capítulo 4”. Entiendo que estos apartados, condensan las ideas principales del escrito. Indago en estas páginas: ¿A quiénes les escribe Paulo Freire? ¿Cuál es el contexto de producción de la obra? ¿Con quiénes dialoga? ¿Cuáles son sus preocupaciones? ¿Qué lugar ocupa la idea de “revolución” en Pedagogía del Oprimido?

Published: November 2020

This work deals with the occurrence of selected antibiotic resistant bacteria in Slovak surface waters. Total and antibiotic resistant coliform bacteria, enterococci and coagulase positive staphylococci were determined in 34 samples of surface water from rivers and still waters (dams, natural lakes, thermal bath) some of them used for recreational swimming. Sampling was performed during summer season 2017 (July and August). The number of total coliforms ranged from 1.74 log CFU/10 mL to 3.69 log CFU/10 mL. Coliform bacteria were registered in each tested sample. The highest number was observed in the sample from river Hron. Majority of samples contained ampicillin and tetracycline resistant bacteria. Enterococci were determined in 70 % of samples ranging from 0.78 log CFU/10 mL to 3.81 log CFU/10 mL. The highest number of enterococci was observed in river Váh. Ampicillin and vancomycin resistance prevailed over ciprofloxacin and gentamicin resistance. Coagulase positive staphylococci were present in 91 % of samples in the range of 0.70—3.03 log CFU/10 mL. Antibiotic resistant coagulase positive staphylococci were observed only in 32 % of samples, predominantly from rivers. In these samples, chloramphenicol resistance predominated. In three samples of water used for recreational purposes, the limit value for enterococci and E. coli according to Slovak legislation (Decree no. 308/2012 Coll.) for the quality of water in natural swimming pools during bathing season was exceeded.
Inclination to self-ignition and analysis of gaseous products of wood chips heating
Authors: Skrizovska Michaela , Veznikova Hana , Roupcova Petra
Published: November 2020

This paper focuses on the assessment of the inclination to self-ignition of various types of wood chips according to the methodology of European standard EN 15188. The study also assesses the effect of heating temperatures on the composition and quantity of gaseous products of heating. Gases were analysed using an infrared spectrometer with Fourier transformation. From the measured results it was found that the inclination to self-ignition differs for various samples of wood chips. The paper discusses certain parameters assumed to affect the inclination of biomass to self-ignite. When assessing the effect of temperature on the composition of gaseous products, a sample of forest wood chips heated at temperatures from 50 to 150 °C resulted in the following gaseous products: carbon dioxide, carbon monoxide, water and aliphatic hydrocarbons; their concentrations increase with the increasing temperature. Carbon oxides have been proposed as indicators of the state of stored materials self-heating. Observations presented in this paper can be used as data for elaborating safety instructions for storage of fuels based on solid biomass.

Published: November 2020

A systematic study of (7,8-dimethylated) alloxazine, isoalloxazine, and their derivatives with substituted N(1) and N(10) positions was conducted using the density functional theory. The main aim of this work was the direct investigation of substituent effect on the molecular structure. Furthermore, HOMED aromaticity indices were calculated to describe the scope of the geometry changes. Frontier molecular orbitals of reference alloxazine, isoalloxazine and lumichrome derivatives were discussed by means of changes in their shape and energy levels. Photophysical properties were analyzed by determination of optical transition energies using the TD-DFT method. Obtained results were compared with previously published experimental data.

Published: November 2020

The choice of phthalates as plasticizers have been on the increase especially in household products. They are ubiquitous environmental pollutants due to their physical attribute. This study was carried out to determine the occurrence and level of phthalates in the groundwater in some regions of Delta State. Groundwater samples were collected from fourteen sampling points and analyzed using standard procedures. The obtained results showed that the concentration (µg/l) of six phthalate ester compounds present in the water samples was of the order: < 0.05 - 0.05 BBP, < 0.05 - 3.71 BEHP, < 0.05 - 0.54 DBP, < 0.05 - 0.55 DEP, < 0.05 - 0.13 DMP, and < 0.05 - 0.48 DnOP. BEHP was observed to be the major compound of the phthalate acid esters present in most sampling stations, whilst others, especially BBP, were found to be in low concentration and does not pose any immediate threat to human health. The presence of BEHP in most samples from different locations suggests an inflow of the phthalate to underground water, hence it becomes imperative for continuous monitoring and a call to various governments and environmental regulatory agencies to establish standards for phthalate esters in order to monitor its presence in the environment.
Process Mining Contributions to Discrete-event Simulation Modelling
Authors: Jadrić Mario , Pašalić Ivana Ninčević , Ćukušić Maja
Published: November 2020

Background: Over the last 20 years, process mining has become a vibrant research area due to the advances in data management technologies and techniques and the advent of new process mining tools. Recently, the links between process mining and simulation modelling have become an area of interest.

Objectives: The objective of the paper was to demonstrate and assess the role of process mining results as an input for discrete-event simulation modelling, using two different datasets, one of which is considered data-poor while the other one data-rich.

Methods/Approach: Statistical calculations and process maps were prepared and presented based on the event log data from two case studies (smart mobility and higher education) using a process mining tool. Then, the implications of the results across the building blocks (entities, activities, control-flows, and resources) of simulation modelling are discussed.

Results: Apart from providing a rationale and the framework for simulation that is more efficient modelling based on process mining results, the paper provides contributions in the two case studies by deliberating and identifying potential research topics that could be tackled and supported by the new combined approach.

Conclusions: Event logs and process mining provide valuable information and techniques that could be a useful input for simulation modelling, especially in the first steps of building discreteevent models, but also for validation purposes.
