Published: July 2022

Utilization of maggot as a substitute for protein source feed ingredients can be a solution to overcome the high cost of feed. However, the inappropriate growth media caused the growth of maggots to be inhibited. Palm kernel cake, vegetable and fruit waste have high nutritional content which has the potential as a medium for growing maggots. The purpose of this study was to determine the best growth of maggot on various growing media. The treatments given in this study were P0A = 100% palm kernel cake; P0B = 100% vegetable and fruit waste; P1 = palm kernel cake 75% + vegetable and fruit waste 25%; P2 = palm kernel cake 50% + vegetable and fruit waste 50%; P3 = palm kernel cake 25% + vegetable and fruit waste 75%. The results showed that the use of growing media from mixing 25% palm kernel cake + 75% vegetable and fruit waste (P3) gave better results as a growth medium for the effectiveness of the growth of maggot. This is due to the nutritional needs of maggots for its growth have been met from the nutritional content and organic matter available in optimum quantities in the growing media. It was concluded that the growing media from palm kernel cake with vegetable and fruit waste had effectiveness in increasing the growth of maggot.

Authors:   Universitas Muhammadiyah Yogyakarta, Purnomo Halim
Published: July 2022

Introduction. The goal of the mediation analysis is to see if the Islamic work ethic has a more significant effect on the instructors' organizational commitment than the direct effects of Islamic organizational culture, leadership, and Islamic spiritual intelligence. The importance of this study is to examine these variables in Islamic context. Materials and methods. The population of this research include teachers of Islamic boarding schools on Java region, Indonesia. Participants included 360 teachers who were selected randomly from Islamic boarding schools and questionnaire was distributed online through google forms. SPSS AMOS was used as a technique for structural equation modeling to evaluate the expected direct effect of variables on commitment. To test the hypothesized indirect effect, Sobel test was employed. AMOS was used to evaluate the structure of interrelationships with one comprehensive technique. Research results. Islamic organizational culture, Islamic leadership, and Islamic spiritual intelligence significantly affect Islamic work ethic with (β=0.085, 0.292, 0.244) Respectively. When it comes to Islamic corporate culture, Islamic leadership, Islamic spiritual intelligence, and Islamic work ethics have a significant impact with (β= 0.060, 0.250, 0.206, 0.112) respectively. The findings of the mediation study reveal that Islamic organizational culture, leadership, and spiritual intelligence influences organizational commitment through Islamic work ethic with (β= 0.019, 0.027, 0.044) respectively. The total effect analysis shows that the most effective path to increase teachers’ organizational commitment is Islamic leadership – Islamic work ethic – organizational commitment. Conclusion. This study evaluates the Integrative Model of Organizational Behavior by Colquitt (2016) applied in Islamic Boarding School. The model consists of contemporary leadership and individual characteristic as the antecedent. The mediating variables of the model consist of individual mechanisms such as trust, justice, and ethic. Individual performance and organizational commitment are the model's outcomes. These variables, on the other hand, do not represent the Islamic viewpoint as a whole. As a result, this study aims to assess the role of Islamic principles in the model. The study employs reliability and validity tests to get reliable and valid measures. The ﬁndings revealed that the evaluation model is proven to improve organizational commitment at Islamic Boarding School. Another theoretical contribution of this research is to provide more information to answer why there are differences in result of research’s.

Published: July 2022

Introduction. Adolescents and young people are one of the largest categories of social media users, they have great confidence in the information presented in the networks and are mostly destructive in nature. The reason for this is that destructive material is perceived by adolescents as credible and used as a guide for deviant or criminal behaviour. Existing conditions and methods of prevention of their desocialisation prove to be ineffective. The aim of the article is to identify social, personal and activity factors and causes of personality desocialization, taking into account the features of personality desocialization of adolescents and young people under the influence of social networks with destructive material, and to determine the basis for the development of a set of social and pedagogical measures to prevent adolescent desocialization. Materials and methods. Adolescents aged 13-17 from Magnitogorsk, Verkhneuralsk, District of Chelyabinsk Region, and Sibai, Republic of Bashkortostan, took part in the study. All in all 1415 people. The author's questionnaire, observations, analysis of statistical data were used. Based on the analysis of their answers to the questionnaire and the analysis of social networking material the grounds for the prevention of desocialization, directions and forms of organization of the process of training teenagers to work in social networks were determined. The results of the study. It has been proved that the problem must be seen as objectively existing and can only be solved by identifying and evaluating social media material (more than 92% receive information from social media only). It has been established that the basis of the problem of desocialization of adolescents and young people is the contradiction between holding their attention by available information, providing them with relative anonymity and the need for everyone to hide their "self". It was revealed that the majority of the adolescents have a low level of personal identification and self-esteem, have signs of inferiority complex and conflict with society (more than 52% of the adolescents communicate mainly with virtual friends; more than 47% of the respondents do not rely on others for help). We propose a method of preventing desocialization through the implementation of a set of socio-pedagogical conditions. Conclusion. Factors in preventing the desocialisation of adolescents and young people include targeted training for educators to educate and prepare adolescents for social media, building their digital competence; targeting a comfortable and authoritative social environment in which their communication, social behaviour and activities take place; and creating conditions for them to engage in interesting and rewarding activities

Introduction. The relevance of the research is determined by the need to identify the possibilities of mutually enriching dialogue of philological and mathematical knowledge in the digital space in the implementation of research work of undergraduates. The purpose of the article is to find ways to improve organizational and methodological tools for the development of research skills of future philologists. In this regard, the authors propose their own concept and specific ways to solve the problem, which consist in supplementing the list of professional competencies in the field of research and development. Materials and methods. Assessment of the formation of research competencies of undergraduates in the process of solving interdisciplinary tasks in a network format was carried out on the control (n1=20) and experimental (n2=20) Diagnostics was carried out on the basis of monitoring the actual results of the activity of research activities of undergraduates. The empirical results of the study were analyzed using a set of mathematical and statistical methods (methods of descriptive statistics φ*-test Fisher). The results of the study. The organization of a communication space for program participants is carried out through the creation of web sites where managers pose professional problems to undergraduates in the humanities, and students of other profiles provide technical or mathematical assistance in solving them with further critical discussion and evaluation of the results obtained. The study illustrates interdisciplinary tasks for philology students based on computer modeling methods and textual analysis. Diagnostics of the formation of research competencies proved the statistical significance of the proposed content and forms of training (φ emp* =2,58 in terms of academic performance of research and φemp*  =2,353 in terms of research activity). Conclusion. The innovative methodology of organizing research of undergraduates in a network format, implemented at Bunin Yelets State University, is effective for various humanitarian areas of training. The actions of undergraduates associated with the formulation, modeling and interpretation of data demonstrate the formation of competencies that reflect key types of research activities in solving professional problems based on the dialogue of cultures.

The Queer Transnational in Kate O’Brien and Elizabeth Bowen
Authors: Murphy Naoise
Published: July 2022

Transnational modes of thought play a constitutive role in the imaginary of Irish queerness. The novels of Elizabeth Bowen and Kate O'Brien offer a dualistic contestation of hegemonic sex/gender conventions that can be theorised as ‘the queer transnational.’ Based on sustained engagement with the thematics of abjection, their writing highlights how the transnational is deeply embedded in the structure of queer imaginaries in Irish writing. Through readings of O’Brien’s novels Mary Lavelle (1936) and The Land of Spices (1942), and Bowen’s The Last September (1929) and Eva Trout (1968), this article proposes ‘the queer transnational’ as a new way of thinking about queer literary histories in the formative years of the modern Irish State.

The so-called tourism of Meetings, Incentives, Conferences and Exhibitions (MICE) is a specialization in the way of doing tourism based on trips whose purpose is mainly business. This specialized variant of tourism has maintained a constant growth during the last decades within the service market. It is a type of tourism recently identified under various characteristics that describe it as a niche market based on the meetings or events industry, or simply business tourism.All its denominations maintain an associated concept.Currently, MICE tourism, being a global industry that focuses its objective on the scope of various productive modalities in the three sectors of the economy, maintains an accelerated and vertiginous growth that has evolved towards highly specialized concepts within the industry, whose interactions maintain constant and vertiginous changes that imply optimal management between customer-service, service-service, industry-industry, industry-services or industry-end customers, fundamentally.The general objective of the present work is to carry out a characterization of MICE tourism throughout its implementation and development, through the realization of national and international exhibitions in fairgrounds designed expressly, events organized with the support of a chain of complementary services that make up a cluster to serve a highly specialized tourism segment. The particular objective is aimed at exposing the benefits that this industry generates throughout its value chain, in the Guadalajara Metropolitan Area (ZMG), cataloged as one of the most important MICE destinations in Mexico.

The province of Santa Fe generates approximately 7.5% of the Gross Domestic Product of the Argentine Republic and is the second Argentine province by the level of exports, combining a relatively diversified productive structure with an export pattern focused on primary agricultural products. Based on this work, part of the approach proposed by Ecological Economics and in particular the concept of socioeconomic metabolism to apply it in order to determine and make visible the “hidden” material flows that can be opaque due to the monetization of variables from an economic study of foreign trade in the province of Santa Fe, Argentina. The study allows us to see that the province of Santa Fe is a net supplier of materials to the rest of the world with a low USD / Tn ratio, obtaining at certain times an mportant exchange balance, but in some periods this exchange rate the balance becomes scarce only with the increase in physical volumes given the high USD / Tn import ratios.
The Effects Of Supply Chain Management On Competitive Advantage: The Case Of Manufacturing Companies In Ethiopia
Authors: Isho Mohammed Yassin
Published: July 2022

Abstract

Now a days firms are not only competing as autonomous units instead they entered in to an era of competing among different supply chains, leading them to work as a team in the form of network of business relationship. As competition becomes stiff, firms must be more involved in how their suppliers and customers conduct their businesses. To succeed in today’s challenging business environment, firms must be able to effectively integrate the internal function within a company and effectively link them with the external operations of supply chain members. Due attention should be given by firms to supply chain management practices as it has significant influence in enhancing SCM functions and ultimately performances. Accordingly, the objective of this study is to examine the practices and effect of supply-chain management on firms’ competitive advantage; and to look at the effect of inventory management on firms’ performance. Moreover, the study attempted to identify major challenges of supply-chain management in selected manufacturing firms in Ethiopia. To attain the objectives quantitative approach was employed. Moreover, a descriptive inquiry along with causal research design was used. Primary data were obtained from survey questionnaires. Large manufacturing firms; 2 textiles and 2 sugars were selected as samples using purposive sampling technique. In addition, 4 officials from each of the eight departments’ viz., General Managers, Purchasing managers, Technical managers, Operation managers, Quality managers, Transport managers, Sales and IT managers were selected from the four firms included in the study. Hence, a total of 128 respondents from each of the three studies were judgmentally selected. The collected data were analyzed using SPSS 20.0 version using descriptive statistics, Correlation analysis and multiple regressions analysis. Accordingly, based on the regression result it is revealed that the supply chain dimensions included in the study viz., customer relationship management, customer service management, level of information sharing, demand management process, environmental issues,  and supplier relationship management were positively and significantly affect firms competitive advantage.  Finally, it is suggested that manufacturing firms should create close relationship with customers to differentiate their products from competitors. Moreover, manufacturing firms are recommended to apply information technology like electronic data interchange within and among the supply chain umbrellas as a whole.

Study and Numerical Simulation of the Electrical Properties of a Duct-Type Electrostatic Precipitator Using Seven Circular Corona Wires: A Review
Authors: Asipuela Angel , Iváncsy Tamás
Published: July 2022

The study of electrostatic precipitators (ESP) is of great importance in powder technology. Different physical and chemical processes occur during its operation. The objective of this investigation is to analyze and observe electrical phenomena using mathematical models such as Poisson's equation and the charge conservation equation. To carry out the simulation two flat plates and seven corona wires are geometrically arranged based on an ESP prototype. The general form of partial differential equations mentioned along with the boundary conditions was written in software and associated with the different parts of the geometry. For example, the electric field onset is calculated by Peak's law and set as one of the boundary conditions for the corona wires. Defining the space charge density distribution is an essential part because the next processes inside of ESP depend on this parameter. A specific method that splits the space charge density is used to solve these PDEs. Besides, a review of the concepts of the particle charging process, particle kinetics, and particle collection is introduced. The results obtained from the simulation such as the electric potential, electric field, and space charge density, agree with those proposed in some investigations.

Published: July 2022

The article reveals the methodological potential of the cosmopolitan approach to the study of collective memory as one of the main prerequisites for the formation of group identity and identification of the foundations for the formation of global memory. For this purpose, the civilizational approach of S. Huntington, the paradigmatic approach of J. Heidt and the methodological apparatus of memory studies with its inherent intention to the problem of forming a group identity are used. These methodological tools helped to explain the whole spectrum of modern civilizational transformations and provided an impartial view of the sources of aggressive policy of russia towards Ukraine’s European choice and entire Western civilization. In view of this, the results of the study can be useful for developing a humanitarian policy appropriate to Ukraine’s European choice, in particular, for elaboration of a strategy for the development of Ukrainian memory policy. It must be developed taking into account the ultimate importance of global (universal) memory for overcoming international conflicts for the sake of peace and prosperity of all mankind and understanding the problematic nature of its emergence in the near future due to civilizational differences and economic inequality. Given this, it is important to the modern world to form supranational communities, whose members being aware of the decentralized nature of global processes and the risks involved will focus on creating a system of interstate mechanisms to overcome turbulence to preserve peace and increase human well-being. Despite the noble intentions of the supporters of the cosmopolitan world based on the principles of liberal democracy, their ideas and programs are discern with great caution, and sometimes even with open hostility in cultural environments and communities with different from European collective experience and historical memory. This, in turn, puts on the list of items the need to unite the entire Western world and construct a supranational pan-European identity as a prerequisite for the internal consolidation of European society around core values defined by shared historical memories that underpins European international policy
Potential use of neuroimaging as a tool to monitor brain imaging changes in politicians related to unethical decision making
Authors: Uludag Kadir
Published: July 2022

Introduction. Political neuroimaging is an emerging field investigating neurological roots of political behavior, while many brain imaging techniques such as magnetic resonance imaging (MRI) and functional MRI provide quantifiable information. However, the literature is scarce on its practical applications in political sciences since it's unclear how it impacts political sciences. Put it simply, how the developments in neuroimaging can be used as a tool in politics, especially to monitor and assess their decision-making related to criminal acts such as corruption, is unclear. In addition, there are potential ethical limitations preventing investigators from using brain imaging to evaluate and monitor the behavior of politicians. The aim of the study was to discuss the potential role of neuroimaging as a political tool. Neuroimaging tools can help us demonstrate specific abnormal behavior associated with politically unethical behavior, such as corruption or deceptive behavior. However, documenting brain imaging findings specific to such deviant behavior may be challenging. Here, we suggest that the practical use of political neuroimaging can improve transparency in the political field. It can be recommended to analyze and have insights into the decisionmaking process of politicians. Furthermore, neurofeedback tools such as electroencephalography can be used to improve politicians' decision-making. Methodology. This study is not a systematic review as the literature is not wide on neuroimaging as a political tool. We have used Google Scholar to search relevant articles to provide background to support it. Review and Discussion. In this study, we have speculated on the potential of measuring politically inappropriate behavior such as corruption and deceptive conduct. To investigate it, we have discussed measuring psychological stability before and after being a politician. More studies are needed to help politicians have stable psychology and improve their decision-making. Therefore, it may help to improve productivity. However, some many confounding factors and limitations prevent achieving such a goal. Conclusion. In conclusion, political neuroimaging can be used to create beneficial tools to improve and ensure the psychological stability of politicians. However, it is controversial how it can be implemented to assess the political behavior of politicians. Thereby, more studies are needed to elucidate the decision-making process related to politicians' decisionmaking. Such advanced tools can help select better politicians and improve their decisionmaking by providing feedback

Bu araştırma, ‘ÇOMÜ Dardanos Yerleşkesi Ziraat Fakültesi Bitkisel Üretim Araştırma ve Uygulama Birimi’nde yer alan ‘Sofralık Üzüm Çeşitleri Uygulama ve Araştırma Bağı’ndaki ‘Amasya Beyazı’ ve ‘Kozak Beyazı’ üzüm çeşitleri üzerinde 2020 yılında yürütülmüştür. Araştırmada, farklı düzeylerdeki salkım seyreltme uygulamalarının Amasya Beyazı ve Kozak Beyazı (vitis vinifera L.) üzüm çeşitlerinde verim ve kalite özelliklerine etkileri incelenmiştir. Bu amaçla her iki çeşit için, her uygulamada 9’ar adet omca belirlenmiş ve omca üzerindeki salkımlar 1/3 ve 2/3 oranlarında seyreltilmiştir. Elde edilen bütün veriler bir arada değerlendirildiğinde; 1/3 oranındaki salkım seyreltme uygulamasının kontrole kıyasla ortalama verimi daha az düşürdüğü belirlenmiş, tane kalitesi ve rengi üzerinde olumlu etkilerinin olduğu saptanmış, ayrıca üzüm olgunluğunu da birkaç gün öne çektiği tespit edilmiştir. 2/3 oranındaki seyrelme uygulaması ise; kontrole kıyasla ortalama verimi daha fazla düşürmekle birlikte, özellikle Kozak Beyazı üzüm çeşidinde tane eni, tane boyu ve tane ağırlığında azalmalara neden olduğundan tavsiye edilebilir bulunmamıştır.

As mudanças decorrentes dos processos de transição demográfica e epidemiológica favoreceram o aumento da prevalência de doenças crônicas não transmissíveis em todo o mundo, dentre elas, destacam-se as doenças do aparelho circulatório, sendo uma das principais causas de morte entre homens e mulheres. A partir de tal contexto, o objetivo deste estudo foi caracterizar e descrever o perfil epidemiológico da mortalidade por doenças do aparelho circulatório no Brasil entre 2016 e 2019. Foram utilizados dados provenientes do Sistema de Informações sobre mortalidade do Departamento de Informática do Sistema Único de Saúde, referentes a mortalidade por doenças do aparelho circulatório no Brasil. Observou-se a maior taxa de mortalidade por doenças do aparelho circulatório na região sudeste, principalmente nos estados de São Paulo e Rio de Janeiro. De acordo com o sexo e a faixa etária, no sexo masculino e na faixa de idade de 60 a 79 anos, foram observadas as maiores taxas de mortalidade, respectivamente. Além disso, constatou-se que a mortalidade foi maior em indivíduos brancos, e no ambiente hospitalar. Portanto, constituem-se como uma das principais causas de morte no Brasil, criando a necessidade de estudos com diferentes abordagens metodológicas para compreender e subsidiar ações de enfretamento da problemática.

Published: July 2022

Electrochemistry at the interface between two immiscible electrolyte solutions (ITIES) has become an important and powerful platform for the detection and characterization of a wide variety of organic and inorganic species. Liquid/liquid electrochemistry overcomes some limitations faced in conventional solid/liquid electrochemistry. These include employment ofion transfer voltammetry across the ITIES as the basis for detection of non-redoxactive ions. The analytical sensitivity increasedon miniaturisation of the interface with an improvement insensitivity due to the enhanced mass transport via convergent diffusionas the size of the ITIES is minimised. In this review article, the ITIES is briefly described along with the scope of electrochemical research at micro-ITIES.

An effective method of water and carbon tetrachloride (CCl4) system has been studied to recover metals ions from spent Li-ion battery cathode materials. Leaching of HCl and HCl + H2O2 has been applied individually to dissolve the collected cathode materials. Metal ions dissolved in HCl and HCl + H2O2 has been treated separately with a solution of hexadecyl amine in CCl4. The formation of metal ions-hexadecyl amine complex has been confirmed from UV-visible spectroscopy. Recovery of metals from the produced complex has been carried out via filtration and calcination. The calcined materials has been characterized using Fourier transform infrared spectroscopy (FT-IR),field emission scanning electron microscopy (FESEM), energy dispersive spectroscopy (EDS) andpowder x-ray diffraction (XRD).

LEARNERS’ PERCEPTION AND ASSESSMENT ON PRINTED OR DIGITAL MODULES (PDM) AS MODULAR DISTANCE LEARNING (MDL)
Authors:   Congressional Integrated High School, Rosel-Espeña Eloisa
Published: July 2022

— The study aimed to determine learners’ personal assessment, performance, and importance in having PDMMDL in this time of the pandemic. The study was qualitativedescriptive in nature. Graduating students from Senior High School (S.Y. 2020-2021) were the respondents of this study. The data were collected by purposive sampling and thru surveys conducted via google forms and ms excel. This study proved that although a face-to-face setup is more helpful to them, still, majority of them are in favor of modular distance learning in this time of the pandemic. Thus, to give notice on the “needs”; and focusing on the “appropriate” activities, strategies, and techniques that are suited to the said mode of learning are highly recommended

This research work has highlighted the benefits of enhancement of arc at Borikiri 33kV Distribution Network in Rivers State, Nigeria. The flash arc analysis was modelled and simulated using ETAP 12.6 software environment to show the sequence of operation of arc flash from the Injection substation to the Transmission Station. The analysis focus on the fault current occurred at some point once the relay protection device issued a clearing time in seconds, the circuit breaker was absolutely tripped and when an arc fault occurs, the latched fault occurred showing that a short circuit that has no electrical resistance at the point of the fault, that is characterised by an absence of arcing. The case study shows the connection between the clearing/tripping time and fault current for the prevailing and simulated case study; for the existing case study shows the minimum values and therefore the most values, once the clearing/tripping time was 0.011 sec, the fault current was 32.20 kA and when the clearing/tripping time was 0.025 sec, the fault current was 34.12 kA, the result show the behavior of the graph as linearity. The graph shows that as clearing/tripping time will increase, fault current increases slowly at first. Similarly, because the clearing/tripping time and the the} fault current will increase slowly at first, then additional rapidly, then slows down once more and reaches a most level. The simulated case study also shows the link between the fault current and clearing time shows the minimum values and the maximum values, once the clearing/tripping time was 0.062 sec, the fault current was 4.62 kA and when the clearing/tripping time was 0.26 sec, the fault current was 5.01 kA, the graph show that as clearing/tripping time increases, fault current increases slowly at first. Relationship between the incident energy, flash protection boundary and clearing time of the prevailing case study; once clearing or tripping time was zero.011 sec, the flash protection boundary was 1.03 feet, and therefore the incident energy of 0.73 cal/cm2 , according to standard for Electrical Safety, our result shows that Hazard Risk categories is 0 (HRC 0) that cause a second degree burn to unprotected skin.
