Tratamiento de efluentes líquidos industriales utilizando quitosano
Authors:   , Pérez Calderón John Freddy
Published: August 2020

Existen diferentes tipos de actividades industriales que generan efluentes líquidos contaminados. Dentro de estos se encuentran las emulsiones estables petróleo/agua y los colorantes sintéticos. En esta tesis doctoral se plantea la necesidad de explorar diferentes alternativas de tratamiento de estos efluentes usando quitosano (QS) como polielectrolito natural. Se estudió la acción del QS para la clarificación de efluentes petróleo/agua donde la emulsión presentaba estabilidad debido a la presencia de un tensioactivo aniónico (dodecil sulfato de sodio, SDS). Utilizando la metodología de superficie de respuesta con un diseño central compuesto rotable se determinaron las condiciones óptimas de desestabilización de la emulsión en función de la concentración de QS y SDS. Para el caso de los colorantes se investiga el uso de QS por medio del proceso de adsorción. Se sintetizaron tres tipos de bio-adsorbentes a base de QS evaluado el poder de adsorción con respecto al colorante Rojo Reactivo 195. Los materiales fueron hidrogeles y matrices bio-compuestas los cuales fueron caracterizados por distintas técnicas. Para finalizar, se usó la matriz bio-compuesta para realizar ensayos dinámicos en columnas de adsorción variando condiciones de ensayo, dichos resultados sirvieron para poder aplicar distintas ecuaciones matemáticas analizando los mecanismos involucrados en el proceso de remoción.

Authors: Solano Jiménez René
Published: August 2020

Los florecimientos de cianobacterias tóxicas son una amenaza para la salud de los ecosistemas acuáticos y de los seres humanos en todo el mundo. En el presente trabajo, mediante un análisis documental, se cuantificó el número de las plantas acuáticas y terrestres reportadas para control de estos florecimientos y las metodologías que se utilizan para determinar la actividad alelopática, con el objetivo de proporcionar a los investigadores un panorama general de los avances realizados en la última década. Se identificaron 74 especies de plantas, 44 macrófitas acuáticas y 30 terrestres. Según la CE50, los compuestos puros son más eficientes que los extractos crudos, con la desventaja de ser más costosos. Finalmente, se determinó que existen 4 técnicas para analizar la actividad alelopática de las plantas sobre las cianobacterias, siendo la experimentación en mesocosmos y en coexistencia las que más se aproximan a las condiciones naturales de un cuerpo de agua.

Published: August 2020

This paper investigated rural-urban differentials in the role of Christian religious organisations in Community Development Programmes (CDPs) in Cross River State. Adopting the survey method, 150 churches were selected from 6 Local government Areas, comprising 3 urban and 3 rural communities across the 3 senatorial districts of Cross River State. Questionnaire was used to generate primary data, and descriptive statistics was employed for data analysis. Using the exchange theory as the basic framework for analysis, the study found that more rural than urban churches do not have autonomy, thus could serve as a hindrance to initiating and implementing CDPs in the study area. Result also shows that membership taxonomy of the church could hinder the goal of CDPs in terms of members’ financing and participation in CDPs in the area. The church has the capacity to promote sustainable livelihood, guaranty social order, spur development, enhance the social functioning of individuals, serve as agent of change, and bring about increased organized commitment and participation in community development activities. It is recommended that the local church should see community development programmes as part and parcel of their ministry.

Published: August 2020

This paper examines the changing work patterns and the factors that are responsible this in the Ibadan Electricity distribution company (IBEDC) located in Ilorin. Strategic Choice Theory was adopted in the explanation of the necessity for change in work patterns. The study is descriptive and made use of both qualitative and quantitative approach. Purposive and random sampling was carried out for the selection of 300 questionnaire respondents from the pool of workers. A detailed analysis is made based on the responses from the questionnaire as well as from the conducted in-depth interviews of carefully selected workers. The paper reveals that customers’ complaints about service delivery accounted for the need for change in work patterns while poor quality of service is the main factor necessitating change in work patterns. Findings also revealed that 64.1% of respondents emphasized that jobs were re-designed which
led to new job descriptions and new work patterns. Finally, the study concludes that the changing nature of work cannot be neglected; the influence of technological innovation, work re-structuring and job re-design were seen to have helped to reshape attitudes among managers and workers.

Authors: Uchea Chekwube A. , Omolawal Samuel A. , Okafor Emeka E.
Published: August 2020

Most studies on outsourced workers in Nigeria did not addressed the issues of their recruitment, placement and workplace experiences along sub-sectoral lines. This study was conducted in Ibadan using ten work organisations covering four sub-sectors. Neoliberal and Systems theory provided the theoretical framework. The design was survey and exploratory. A two-stage sampling consisting of purposive and simple random techniques were used to select work organisations and respondents. Questionnaire was used to elicit information. In addition, twenty in-depth interviews and ten key informant interviews were conducted with outsourced workers across organisations and management representatives respectively. Most respondents across the sub-sectors felt they were placed in peripheral positions. Management confirmed that there were disparities in the kinds of incentives given to outsourced and permanent workers. Outsourced workers’ experiences varied along sub-sectoral lines. Efforts should be made by government and management of work organisation to improve the working conditions of outsourced workers.

The family structure of older Nigerians is projected to change dramatically as a result of increasing levels of single-person and couple-only households, very low fertility, non-marriage, childlessness, and divorce, and declining intergenerational coresidence. This study examined the structure of the family system on the utilization of healthcare services among older persons in Ajah community, Lagos State. It has been well established that the changing family structure influences the wellbeing of older people in the society. The study employed the Family Systems and Dependency paradigms as theoretical frameworks to analyse the subject matter. The study adopted purposive sampling method to select participants and respondents for qualitative data. Findings revealed that parent-children relationship and support of family members (especially children) are closely linked with appropriate usage of healthcare facilities by the elderly.
Civil Society Organisations and Democratic Consolidation in Nigeria
Authors: Suleiman Amali , Ilim Msughter Moses
Published: August 2020

The 2015 general election was without doubt marred by violence in some areas, as reports in Rivers, Delta, Akwa-Ibom, and Benue states among others suggested. The general outcome of the election however revealed that the alleged incidences of violence were not enough to compromise the credible and transparent nature of the 2015 polls. The Independent National Electoral Commission (INEC) was given a pat on the back for organising an election that was largely adjudged free, fair and credible. However, interest groups such as the Civil Society Organisations (CSOs) have been playing significant role since the reintroduction of civil rule in Nigeria to ensure that the nascent democracy is sustained. The CSOs ensure that there is peaceful conduct of the electorates before and during elections, which is mainly achieved through voters’ education across the country, and monitoring of election at polling units on election days. This paper is an attempt to highlight the key roles played by the CSOs in sustaining Nigeria nascent democracy. Employing the functionalist perspective, the paper highlights the role played by these organizations towards consolidating the Nigerian democracy. The research relied on secondary data and concluded that the CSOs play an important role in ensuring violent free elections in Nigeria; hence democratic consolidation. The paper therefore recommends that government should partner more with CSOs to sustain the ethos of democracy in Nigeria.

Authors: Dragavtseva I. A. , Kuznetsova A. P. , Klyukina A. V.
Published: August 2020

The stability of fruiting of fruit crops is highly dependent on exposure to natural environmental factors, primarily climate. For fruit crops (especially stone fruit) most destructive were negative air temperatures in winter and spring, which was revealed with the execution of this research. With the aim of developing a new approach to stabilization of production process of fruit crops in conditions of climate fluctuations assessment of plant adaptation of two peach cultivars (Golden Jubilee and the Veteran) in different ecological zones of horticulture (the Kuban and the Western foothills of the Krasnodar territory) for two long periods - 1985-2000 and 2001-2020), covering climate change. The new approach provides for the evaluation of plant production process of the studied cultivars on the manifestation of their adaptation to low temperatures in the winter-spring period in the particular phases of ontogenesis, with the consideration of the fluctuations of climate. The matrix of flower buds stability of the studied peach cultivars was worked out for each phase of winter-spring development. The probability of occurrence of stressful temperatures that destroy their crops over two long periods of years, taking into account climate change, was established. The most vulnerable periods of onset of temperature stress for peach cultivars in various areas of horticulture were identified. It shows the change in the ranks of their adaptation to the destructive temperatures of the winter-spring period (in time and space). Suggestions are given for adjusting the rational placement of peach cultivars, taking into account the success of the production process. The algorithm of a new approach to the stabilization of the production process of cultivars of fruit crops is presented.

Authors: Smykov A. V. , V. Mesyats N.
Published: August 2020

The article shows the relationship of the yield of four promising forms of peach with its most limiting factors. The equations of multiple regression are also presented, which allow us to predict the yield of the studied forms. In form Veteran free pollination the coefficient of multiple regression was R = 0.95, the coefficient of multiple determination was R2 = 0.90; in the hybrid form Zlatogor x Uspar-1 80-367, respectively, 0.99 and 0.98; in the form Lauréat x Zlatogor 73-3 - 0.96 and 0.92; the form (Podarok Kryma free pollination x Tovarishch) 85-104 - 0.98 and 0.96. These coefficients show the degree of dependence between productivity and factors included in the study. Selected hybrid forms should be used in breeding for adaptability to improve the existing assortment of peach. The hybrid form Veteran free pollination was transferred to the State Commission of the Russian Federation, as a cultivar Sarabuz, which is of interest for breeding and production as a promising table cultivar with fruits of medium ripening time.
Outcomes Management in a Real-World Evidence Context: The Case of Abiraterone and Enzalutamide in the Treatment of Metastatic Castration-Resistant Prostate Cancer
Authors: Cardoso Pedro , Santos C. , Costa F. , Rocha-Gonçalves Francisco
Published: August 2020

At present, for patients with metastatic and castration-resistant prostate cancer, European Society for Medical Oncology and National Comprehensive Cancer Network guidelines recommend enzalutamide (E) or abiraterone (A). There are still a few studies comparing both drugs in a real-world setting, thus, in this article, we discuss an outcomes management methodology, supporting the follow-up of patients. This involves measuring relevant baseline traits and outcomes, such as overall survival (OS), treatment duration, patient-reported outcomes, and adverse events. We include 38 men in the A group and 15 in the E group. When comparing the survival of both drugs, both present similar OS. Regarding the quality-of-life analysis (QoL) with EPIC26, reported Standard QoL score was 58.3% in our patients, which was in line with the European Organization for the Research and Treatment of Cancer reference. As a result, by showing that we can capture the distinctive clinical benefits of A and E, and that patient-reported outcomes can be systematically collected for more than 2 years per living patient, we can now incorporate these findings in clinical discussions, risk-sharing agreements, or policy-level arguments.
The Canvas LMS Systems’s Advanced Possibilities in Course Design and the Usage of Evaluation Informal, Non-formal and Informal Education
Authors: Abonyi-Tóth Andor
Published: August 2020

From the 2016’s academic year, the Eötvös Loránd University, in addition to the Moodle framework, also enabled teachers to use the OpenSource version of the Canvas LMS, not only for courses related to formal education but for course-based or even open courses (MOOC). An essential aspect of choosing the framework was to have built-in features which support advanced approaches to the course management and evaluation (e.g.: teamwork, peer re-view, advanced module organization, student differentiation, collaborative opportunities, outcome-based education, rubrics). In my article, besides presenting the usage of the mentioned functions in education, I also summarize the statistics of the usage of this system as well as the teacher's feedback.

Published: August 2020

The topic of the study of the long-range effect in the formation of nanostructured topocomposites under conditions
of ion-plasma exposure is updated. The features for the concentration dependences for the distribution of
elements in the surface layers during the formation of two-layer film—base system are studied. It is established
that under the conditions of the cascade crossover effect at significant depths, the formation of locally inhomogeneous
regions occurs in the material of the carbide base, which leads to increase in the microhardness of the
material. Within the framework of the developed simulation model, the contribution to the change in the concentration
dependences of temperature, various diffusion mechanisms, and the pressure gradient contributing to the
manifestation of the long-range effect is established and differentiated. Explanation of the formation of hardened
sublayers in the carbide-based topocomposites and their role in the manifestation of the long-range effect is given
based on generalization and analysis of the dynamics of competing processes of braking—accelerating diffusion.
COVID-19: Drug Delivery System, Drug Discovery and Therapy Options
Authors: K R Kumar Prithiv
Published: August 2020

Drug delivery system plays a vital part in destroying the pandemic. Few options on drug delivery is been highly considered. One such delivery is emulsifying system. This system plays important role in reducing water compounds in order for the virus to hunt for an environment to sink in.One of the best options to destroy the virus has few setbacks. They have limitations in precipitation of drugs, formulation design, lack of results in vivo conditions and fatty acids oxidation. Generally polymers containing lipid based formula supercedes the drug after dispersion, in this case they improve environment for virus survival. But there is a solution to tackle this superstition. Usage of triglycerides with medium dose enhances antioxidants of unsaturated fatty acids, thus overcoming the problems. Further steps and usage of this delivery system are discussed along with their limitations.COVID-19 possess challenge for discovery of drugs owning to their ability to cause community and health care associated outbreaks. They destroy respiratory organs causing death. This review will also focus on drug discovery options and virus based and host based therapies.

COVID-19 is a serious coronavirus disease that is spreading all over the world. As of the date of this publication, 2.834.134 people have been infected with COVID-19 and 197.924 deaths have been recorded in 185 countries (John Hopkins Corona Resource Center, 25th April 2020) [1]. This overwhelming mortality rate requires intensive research activities around the world. To date, the number of deaths per day in the United States is still killing, indicating an uncontrollable state of infection spread. SARS-CoV-2 binds to the angiotensin II receptor in various tissues of the human body, particularly in the oral cavity and tongue. SARS-CoV-2 requires the cheerful TMPRSS2 to activate this inertia. SARS-CoV-2 uses the ACE2 receptor as a gateway to the lungs. The SARS-CoV-2 virus binds with the spike protein to the ACE2 receptor. COVID-19 is more common among African Americans in the USA (Science 10th April 2020). The comfort and the emotional loading capacity of the employees in the health service are key components for the maintenance of the essential health services during the outbreak of the COVID-19 virus (Coronavirus) [2,3]. Hence, it will be important to anticipate the charges linked with this work and to release support for employees in the health service. The supervision and assessment of the psychic health and the well-being of the employees in the health service will be important, just as the efforts to guarantee a successful reunion with colleagues if they are infected.

Published: August 2020

Loss of heart cells lead to heart attack. The blood flow slows down, eventually pumping gets effected. Several surgeries only weaken the heart. The solution to heart trouble is rather underlying mechanism to derive into regeneration. Several clinical trials have highlighted that stem cells have a promising effect in regeneration. More methods such as cardiac stem cells, bone marrow based cells, mesenchyme stem cells; embryonic stem cells have been effective to an extent. There have been some inconsistencies as well in these methods. Performance of heart has lowered; efficiency to pump blood has influence on selection of type of stem cells. However, future of therapies has to rely on technology. Not just ordinary technology, but nanotechnology. The future of heart repair and advancement of stem cells to cure any heart disease. Nanotechnology helps in understanding cellular layers of heart tissue, which plays a vital role for any heart repair or regeneration. This review discusses the aspects of nanoparticles and nanogel effect in curing heart. Nanoparticles have been effective in drug delivery, targeting particular area of cure. Meanwhile nanogel helps in navigating the drugs and creating a sustainable environment for treatment. Another concept highlighted in this review is nanopatch along with nano material or nanocells communication, helping in regenerative therapy. Thus key issues for future prospects are discussed below.

Authors: Manico Juarês Bongo , Leonido Levi , Gouveia Luis Borges
Published: August 2020

O processo de produção de carvão em Angola produz grandes danos para o meio ambiente e uma grande quantidade de resíduos. Dada esta situação e que cria um cenário desagradável, elaborou-se o objetivo de se produzir e avaliar briquetes a partir do pó de carvão, restos de folhas de repolho, caroços de milho e alguma serragem usado na comunidade de Canjonde, visando seu uso tecnológico como fonte energética. A serragem foi obtida a partir de uma pequena carpintaria na sede da comuna do Ussoque, do município do Londuimbali, que dista a 16 km de Canjonde. Foram avaliados de forma comparativa três tipos de briquetes produzidos a partir de resíduos: Briquete tipo 1. Produzidos a partir de pó de carvão, restos de folhas de repolho e caroços de milho.  Briquete tipo 2. Produzidos a partir de pó de carvão, serradura e caroços de milho. Briquete tipo 3. Produzidos a partir de pó de carvão e caroços de milho. Os briquetes produzidos mostraram-se como uma nova fonte energética a ser utilizada, ajudando ainda mitigar os impactos causados pela exploração predatória das florestas nativas. Os principais resultados da experiencia comparativa da eficiência foram que O briquete tipo 1, produzido a partir de pó de carvão, restos de folhas de repolho e funge de farrelo de caroços de milho numa proporção (60%, 30% e 10%), foi o briquete que apresentou as melhores características estruturais, bem com outros briquetes produzidos com os mesmos componentes e distintas proporções como comparado com o resto de briquetes produzidos com outros componentes. O tempo empregado para a produção e muito parecido entre os três tipos de briquetes, sendo o briquete tipo 2, o mais rápido, seguido do briquete tipo 3, cuja dificuldade na mistura aumenta um bocado pelo que o tempo empregado e sensivelmente superior (apenas) e por ultimo o briquete tipo 3, que se aumenta o tempo já que previamente os resíduos agrícolas devem ser carbonizados.

O presente artigo, através de uma revisão bibliográfica, apresenta os métodos usados na investigação e no ensino-aprendizagem da Economia. Como ponto de partida, levantamos a questão: quais são os métodos aos quais os professores podem recorrer para realizar pesquisas e mediar o ensino-aprendizagem na disciplina de Economia ou outras equiparadas? Para responder, fixamos o objectivo principal de analisar a metodologia recomendável para pesquisa na Ciência Económica, assim como os métodos de ensino-aprendizagem nesta disciplina. O estudo mostra que a Ciência Económica, apesar de se enquadrar no grupo das Ciências Sociais, tem uma particularidade que permite aos pesquisadores recorrerem a diversos métodos, tanto os aplicados em Ciências Factuais quanto aos usados nas Ciências Formais. No Ensino da Economia preconiza-se os métodos activos. Todavia, por si só, estes métodos não permitem alcançar perfeitamente os objectivos de aprendizagem.

Este trabajo se centra en el uso de compuestos bis-fluorofóricos en agua real para la detección y remoción de iones metálicos presentes en el río Tijuana, para esto se utilizó un trabajo previo de análisis químico y bacteriano de 6 muestras diferentes que se tomaron del Río Tijuana. Todos los sitios de muestreo fueron seleccionados cuidadosamente para obtener una comprensión precisa del estado actual del río a lo largo de su curso. Los resultados de TOC, DQO, DBO, Nitrógeno y fósforo mostraron que las presas no contienen cantidades elevadas de estos parámetros, pero al centro de la ciudad estos valores se incrementan por la posible interversión de conexiones del alcantarillado de la ciudad al río (55, 189, 131, 11.9 y 1.1 mg/L, respectivamente). Los puntos con mayor cantidad de materia orgánica fueron en el centro de la ciudad, por lo que se eligió ese punto en específico para la prueba de los compuestos bis-fluorofóricos, para asegurar la presencia de iones metálicos en el agua y se mostró que el agua que contiene compuestos fluorescentes y en presencia de estos compuestos bis-fluorofóricos hay un abatimiento de la fluorescencia. El análisis bacteriano mostró que el último punto de la ciudad, cerca de la frontera de USA y México, se concentra una cantidad elevada de bacterias y que la descarga va directo al océano pacífico, siendo un problema de salud y ambiental.
Training Foreign Students of Medical University
for Medical Practice in Hospitals

Published: August 2020

Скорость и качество овладения русским языком иностранными студентами, обучающимися
в медицинских вузах России, во многом зависят от того, имеется ли у этих студентов возможность пройти предварительную языковую подготовку на подготовительном факультете. В условиях ее отсутствия студенты получают образование на языке-посреднике, а русский язык становится факультативной дисциплиной, в результате чего погружение в русскую культуру, понимание правил невербальной коммуникации в русскоязычной среде, равно как и просто уверенное владение русским языком становятся уделом избранных лиц. Вместе с тем каждый иностранный студент должен проходить практику в русских медицинских учреждениях. В связи с этим перед преподавателем русского языка как иностранного встает несколько задач, к числу которых относится не только общеязыковая подготовка иностранных обучающихся к прохождению медицинской практики, но и речевая, культурологическая и психологическая. Успешной реализации поставленных задач может способствовать создание и использование на занятиях специального словаря-разговорника, который позволит студентам заблаговременно познакомиться с правилами поведения в больнице, освоить необходимый для практики лексический минимум, ввести в активный речевой оборот ряд фраз, актуальных в повседневном общении медперсонала с больными. В статье раскрывается и объясняется структура словаря, обозначены его задачи и целевая аудитория.

The speed and the quality of mastering the Russian language by foreign students studying at medical universities in Russia largely depend on whether these students have the opportunity to take a preliminary year-long Russian language course at the preparatory division. If the students receive education in the English language, the Russian language program is reduced to an optional course, not sufficient to ensure understanding of Russian culture and rules of non-verbal communication in a Russian-speaking environment. However, every foreign student must undergo practical training in Russian medical institutions. In this case the Russian language teacher faces an almost insurmountable task of equipping students with the skills of communicating with Russian patients and colleagues and with sufficient cultural and psychological awareness for adequate verbal and non-verbal behavior in a hospital environment. The successful implementation of these tasks can be facilitated by developing and using a special vocabulary-phrase book at the lessons of the Russian language. This manual will allow students to get acquainted with the rules of behavior in the hospital in advance, master the lexical minimum necessary for practice and introduce a number of phrases that are relevant in everyday communication of medical staff with patients. The article reveals and explains the structure of the manual, identifies its objectives and target audience.

В статье рассматривается роль руководителя при общении с подчиненными как один из факторов, детерминирующих возникновение синдрома эмоционального выгорания. Анализируются концептуальные подходы к изучению синдрома эмоционального выгорания. Недостаточная осведомленность руководителя о синдроме и его симптомах снижает эффективность бизнес-процессов. Вместе с тем информированность о проявлениях эмоционального выгорания помогает руководителю правильно выстроить коммуникативный процесс в организации, что способствует не только налаживанию благоприятного климата в коллективе, но и развитию организации. Данные выводы экспериментально подтверждены на примере исследования, проведенного среди провизоров и руководителей аптечной сети.

, the incidence of radio activity is weakly dependent on stellar mass and independent of stellar age, while radio luminosity depends strongly on stellar mass. Optical nuclear activity incidence depends most strongly on the Dn4000 line index, a proxy for stellar age, with an active fraction that is ∼10 times higher in the youngest versus oldest PSB galaxies. Since a similar trend is seen between age and molecular gas fractions, we argue that, like in local galaxies, the age trend reflects a peak in available fueling rather than feedback from the central black hole on the surrounding galaxy.
A Comparative Study of Host Galaxy Properties between Fast Radio Bursts and Stellar Transients
Authors: Li Ye , Zhang Bing
Published: August 2020

Recent arcsecond localizations of fast radio bursts and identifications of their host galaxies confirmed their extragalactic origin. While FRB 121102 resides in the bright region of a dwarf star-forming galaxy, other FRBs reside in more massive galaxies and are related to older stellar populations. We compare the host galaxy properties of nine FRBs with those of several types of stellar transients: from young to old populations, long-duration gamma-ray bursts (LGRBs), superluminous supernovae (SLSNe), SNe Ibc, SNe II, SNe Ia, and short-duration gamma-ray bursts (SGRBs). We find that the stellar mass and star formation rate of the FRB host galaxies, taken as a whole sample, prefer a medium to old population, and are against a young population, similar to LGRBs and SLSNe by a null probability of 0.02. Individually, the host of FRB 121102 is consistent with that of young population objects; the environment of FRB 180924 is similar to that of SGRBs; and the environment of FRB 190523 is similar to those of SNe Ia. These results are consistent with the magnetar engine model for FRBs, if magnetars produced from extreme explosions (GRBs/SLSNe) and those from regular channels (e.g., those producing Galactic magnetars) can both produce FRBs.

Authors: Nebus F. , Gažovová S.
Published: August 2020

The paper presents the mathematical model of the localization of electromagnetic sources in near-field region based on the sources localization mathematical model valid for the far-field region. The aim of the article is to show similarities and differences between both models with a deeper focus on near-field region model analysis using planar equidistant sensors array. Although both concepts in a high-level mathematical description apparatus look very much the same, in details the near-field region model reconstruction process is more complex with different constrains. Detailed covariance matrix analysis and statistics of the covariance matrix represents the main part of the article. In the conclusion, paper shows some model verification results for the localization of single source, correlated sources and coherent sources.
The Business Transformation Framework and Enterprise Architecture Framework for Managers in Business Innovation
Authors: Trad Antoine
Published: August 2020

The AMM is supported by a real-life case of a business transformation architecture in the domain of enterprise asset management (EAM) that is supported by the alignment of a standardized enterprise architecture blueprint. This chapter proposes an assets alignment pattern (AAP) and offers a set of solutions in the form of design, technical, and managerial recommendations to be used by the target company's asset analysts and enterprise architects to implement EAM solutions in the context of business transformation projects (BTP). Heuristics is applied in real-world complex problems that are very similar to transformation projects. The EAM-based AAP is not influenced by any specific business domain and has a holistic approach that uses a neural networks processor.

Published: August 2020

One of the key applications of AI algorithms in power sector involves forecasting of stochastic renewable energy sources. To manage the generation of electricity from solar or wind effectively, accurate forecasting models are imperative. In order to achieve this goal, a sophisticated hybrid neural network formulation is discussed here in this chapter. long-short-term memory and recurrent neural networks combination is formulated for very short-term forecasting of wind speed and solar radiation. In intervals of 15 and 30 minutes, time series forecasts are made that are ahead by multiple steps. For maximum energy harvest, both point wise and probabilistic forecasting approaches are combined. Historic data is collected for solar radiation, wind speed, temperature, and relative humidity, and are used to train the model. The proposed model is compared with convolutional and LSTM neural network models individually in terms of RMSE, MAPE, MAE, and correlation, and is identified to have better forecasting accuracy.

Published: August 2020

A CFD analysis using ANSYS Fluent software was conducted to study the effects of collector slope on solar chimney's performances. Three solar chimney configurations, named A, B, and C, which correspond, respectively, to an inclination angle of the collector roof of 0°, 2.5°, and 5°, were investigated. The results show that the thermodynamic performances of the solar chimney were improved by increasing the inclination angle of the collector roof. In fact, the power extracted from the sloped solar chimney power plants increases with increasing the inclination angle and the solar radiation intensity, while it achieves a maximum at 800 W/m2 for configuration A. The energetic and the exergetic analysis show that configure B has the best performance in terms of conventional, effective, and total efficiencies of the collector and in terms of exergy destruction ratios in both the collector and the transition section. Whereas, configuration C has the highest amount of power extracted and the best overall energetic efficiency.
Entrepreneurial Innovative Network and the Design of Socio-Economic Neural Systems
Authors: Tikhomirova Olga
Published: August 2020

This article aims to establish how an idea becomes an innovation and how creativity, collective dynamics, and information are interconnected. The results of the author's study showed that the emergence of innovations is closely connected with collective collaboration, and that it is impossible outside of group dynamics. The process of self-organization and collective decision-making is realized through a synergistic interaction, which then transforms into the so-called “information laser” and serves as a basis for the emergence of innovation. Both individuals, as persons and as separate entrepreneurs, are the elements of the innovation system and the actors of the artificial neural network, socio-economic neural systems (SENS-systems). These systems act through self-organization and corporate collaboration, and the efforts of each element are amplified through the interaction with the other elements. The model of the SENS-systems can explain how the individual idea transforms into innovation and spreads throughout the world.
Learning Link in Organizational Tacit Knowledge Creation and Dissemination
Authors: Baporikar Neeta
Published: August 2020

Knowledge that is not well managed and shared disintegrates easily, especially, tacit knowledge that resides in the mind and is accumulated over time. In the realm of knowledge management processes, knowledge sharing is vital yet probably the most difficult one. Knowledge sharing refers to the transference of knowledge among individuals, groups, teams, departments, and organizations. It is also the building block for the success of the organization as it provides a competitive edge. However, many factors that affect knowledge-sharing behaviors include personal characteristics, characteristics of groups, organizations, trust, culture, etc. Different researchers have identified and explained various antecedents to knowledge-sharing behavior. However, the purpose of this conceptual article is to uncover the issues in knowledge sharing and transfer, particularly investigate the learning link in organizational tacit knowledge creation and dissemination.

Authors: Haile Eshetu , Shankar Bandari , Seid Eleni , Shekar Raja
Published: August 2020

This paper presents analytic study of heat and mass transfer in a two-dimensional, unsteady flow of Maxwell nanofluids over a horizontal stretching sheet. The non-linear governing equations with the relevant boundary conditions have been simplified by using similarity transformations and the resulting equations are solved by using the homotopy analysis method. The convergence and accuracy of the solutions are verified. Impacts of magnetic field, thermal radiation, heat source, surface permeability and chemical reaction on velocity, temperature and nanoparticles volume fraction profiles are examined and presented in graphical and tabular forms. The study reveals that increasing the effect of heat source maximizes the temperature profile whereas it reduces the nanoparticle volume fraction profile in the boundary layer. On the other hand, the increase in chemical reaction is found to enhance the nanoparticle concentration.

Electrochemical Treatment of High Concentration Ammonia using RuO2/Ti Anode and TiO2 Nanotube Cathode
Authors: Lee Sumin , Pak Daewon
Published: August 2020

Objectives:In this study, the treatment potential of ammonia in wastewater generated by S company odor removal process was tested by using electrochemical reactor with RuO2/Ti anode and TiO2 nanotube cathode. The effect of chlorine ion concentration and current density on ammonia oxidation were investigated by comparing the treatment efficiencies.Methods:380 mL of wastewater was electrolyzed for 3 h using 4 anodes and 5 cathodes and pH, NH3-N, NO3--N, and TN were measured and analyzed every 30 minutes.Results and Discussion:As the addition of chlorine ion increases, about 1,700 mg/L of ammonia in the wastewater was found to increase in oxidation reaction rate due to an increase in chlorine based oxidizing agent. An increase in chlorine based oxidizing agent leads to an increase in indirect oxidation. As a result, total nitrogen removal was increased. Ammonia oxidation rate was increased as the current density increased. Nitrate, ammonia oxidation byproduct, was accumulated at a current density from 20 to 40 mA/cm2. At higher than 50 mA/cm2, nitrate was accumulated for a while and then decreased. Total nitrogen removal rate increased as the current density increased. During electrochemical oxidation of ammonia to nitrate, hydroxyl ions were consumed by the reaction. The hydroxyl ion consumed during ammonia oxidation was less than that produced from nitrate reduction.Conclusions:Thus, ammonia in actual wastewater was completely removed using RuO2/Ti anode and TiO2 nanotube cathode and the possibility of reducing nitrate was confirmed. We confirmed the applicability of the two electrodes to the real industry.
