Development of Livelihood Skills through School-Based, Agripreneurship Projects Integrating Youth-Adult Partnerships: The Experiences of Youth Partners in Uganda
Authors: Mukembo Stephen , Edwards M. Craig , Watters Craig
Published: December 2020

quipping young people with livelihood skills is essential for positive youth development and empowerment as they transition into adulthood to become productive and engaged members of their communities. In Uganda, which may be the case in other nations of Sub-Saharan Africa, and elsewhere, even though many youth are becoming better educated and graduating from high schools and colleges, a majority of these graduates remain either unemployed or underemployed. Many have not acquired the necessary skills to transition from school to becoming employable and self-reliant. This phenomenon has been attributed to an outdated curriculum that does not meet the needs of contemporary times. Further, the mode of instruction in most of Uganda’s schools is teacher-centered and provides little room for student engagement and creativity to generate new knowledge, to have authentic learning experiences, or to reflect. Such challenges may be overcome through student-centered learning approaches involving School-Based, Agripreneurship Projects (SAPs) that integrate Youth-Adult Partnerships (YAPs), as were explored in this study. Evaluation of the students’ experiences through deductive and inductive thematic analysis indicated that they acquired knowledge in poultry science, business, agripreneurship, and life skills, including better communication, leadership, and conflict resolution practices. Longitudinal studies should be conducted to determine the longterm effectiveness and impact of SAPs facilitated by Y-APs on improving youth livelihoods, especially that prepare them with the life skills necessary to be productive citizens. Such research could involve cohort or panel investigations. Keywords: entrepreneurship; positive youth development (PYD); project-based learning (PjBL)
A single-beam photothermal interferometer for in situ measurements of aerosol light absorption
Authors: Visser Bradley , Röhrbein Jannis , Steigmeier Peter , Drinovec Luka , Močnik Griša , Weingartner Ernest
Published: December 2020

Abstract. We have developed a novel single-beam photothermal interferometer and present here its application for the measurement of aerosol light absorption. The use of only a single laser beam allows for a compact optical set-up and significantly easier alignment compared to standard
dual-beam photothermal interferometers, making it ideal for field measurements. Due to a unique configuration of the reference interferometer arm, light absorption by aerosols can be determined directly – even in the presence of light-absorbing gases. The instrument can be calibrated directly with light-absorbing gases, such as NO2, and can be used to calibrate other light absorption instruments. The detection limits (1σ) for absorption for 10 and 60 s averaging times were determined to be 14.6 and 7.4 Mm−1, respectively, which for a mass absorption cross section of 10 m2 g−1 leads to equivalent black carbon concentration detection limits of 1460 and 740 ng m−3, respectively. The detection limit could be reduced further by improvements to the isolation of the instrument and the signal detection and processing schemes employed.
“This Generation”: Reconsidering Mark 13:30 in Light of Eschatological Expectations in Second Temple Judaism
Authors: Winn Adam
Published: December 2020

Mark 13:30 has received significant interpretive attention in the history of NT scholarship. Much of the attention given to this text finds its origin in concern over whether Jesus has erred in his prediction of his parousia and the culmination of the eschaton. As a way forward in resolving this long recognized problem of Jesus making an errant prophecy, this study considers other interpretive difficulties presented by Mark 13:30, including its tension with Mark 13:32 and its reception by the Matthean and Lukan Evangelists. As a means of addressing these difficulties, the study, like many before it, reconsiders the meaning of γενεὰ in Mark 13:30. Unlike previous studies, this study considers the “generation” concept within the eschatological expectations of Second Temple Judaism. The meaning of γενεὰ that emerges from this analysis not only resolves the various interpretive problems of Mark 13:30 but also provides significant coherence to the entirety of Mark 13.

In the course of the study, it was found that crowdfunding companies follow a certain stage in their functioning and development: choosing a platform; category selection; the wording of the crowdfunding campaign; definition of a financial goal; determination of the project duration; definition of a reward system; creating a video message; description of the project; regular updates; monitoring the fundraising process. By conducting research on the international market, it was found that with a market size of $ 358.28 billion and a share of 85.99%, China is the largest crowdfunding market in the world. Also, it should be noted the Asia-Pacific region, as Australia took 4th place with funding of $ 1.49 billion, and South Korea - 5th place with $ 1.13 billion, we also find other countries in the Asia-Pacific region in the list of the largest crowdfunding countries in the world. The results of our study concluded that there are many players in crowdfunding in Europe, especially in the field of P2P lending, compared with the Americas and the Asia-Pacific region, as a whole it is a small region. The article also notes the advantages and disadvantages of the crowdfunding development in modern conditions of market functioning.
Candidate Selection Reform in South Korea: The Persistence of Exclusive Practices Despite Inclusive Rules
Authors: Woo Eun Hee
Published: December 2020

This paper analyzes how democratization has affected the dynamics of candidate selection in South Korea. After democratization in the late 1980s, it was expected that intra-party democracy would follow. In response to increasing public demand, the major parties adopted primary systems
in the early 2000s. Nonetheless, most candidates for the legislature are still nominated by a small number of central party elites without additional ballots in the local branches. To explain the persistence of such exclusive, centralized features of candidate selection, I highlight the limited
impact democratization has had on the political environment in which the parties operate. More specifically, since the 1987 democratization process resulted in a compromise agreement established by a small number of party leaders, South Korea retained much of the political legacy from authoritarian
times, such as an electoral system advantageous to the major parties and legal provisions restricting electoral campaigns, party activities, and political participation. The continuation of these political institutions makes radical candidate selection reform highly unlikely as the party elites
have no incentive to expand and decentralize the selection process. Without significant changes to the political institutions at the national level, the dominance of the central party elite over the final outcome of candidate selection looks likely to continue for the foreseeable future.
Singapore's Pandemic Election: Opposition Parties and Valence Politics in GE2020
Authors: Oliver Steven , Ostwald Kai
Published: December 2020

Singapore's 2020 general election was held amidst the most serious public health and economic crises in the country's history. Despite expectations that these parallel crises would precipitate a flight to safety and result in a strong performance by the dominant People's Action Party
(PAP), the ruling party received its third-lowest popular vote share (61.2 percent) and lowest-ever seat share (89.2 percent) since independence. This article engages explanations for the unexpected results and argues that the vote swing against the PAP was enabled by a hitherto largely overlooked
factor: the 2020 election included two opposition parties that could credibly compete with the PAP on the valence considerations that drive voting behaviour in Singapore, giving voters a perceived safe alternative to the PAP at the constituency level. Quantitative tests support the notion
that party credibility—rather than demographic factors, incumbency advantages, Group Representation Constituencies, or assessments of the PAP's fourth- generation leaders—best explains variation in the vote swing against the PAP. Ultimately, the results suggest that the PAP's monopoly
on party credibility is no longer assured, thus portending greater opposition competitiveness and pressure against the PAP in future elections. Nonetheless, the PAP's dominance remains intact and there is little evidence of a general appetite among the electorate for a non-PAP government,
suggesting the likelihood of smaller course corrections rather than major steps towards democratization in the coming years.
A Methodological Review of Machine Learning in Applied Linguistics
Authors: Lin Zhiqing
Published: December 2020

The traditional linear regression in applied linguistics (AL) suffers from the drawbacks arising from the strict assumptions namely: linearity, and normality, etc. More advanced methods are needed to overcome the shortcomings of the traditional method and grapple with intricate linguistic problems. However, there is no previous review on the applications of machine learning (ML) in AL, the introduction of interpretable ML, and related practical software. This paper addresses these gaps by reviewing the representative algorithms of ML in AL. The result shows that ML is applicable in AL and enjoys a promising future. It goes further to discuss the applications of interpretable ML for reporting the results in AL. Finally, it ends with the recommendations of the practical programming languages, software, and platforms to implement ML for researchers in AL to foster the interdisciplinary studies between AL and ML.

The scope of environmental disclosure in the European healthcare sector - an empirical study
Authors: Macuda Małgorzata , Ruiz Toledo Marcelo Andrès
Published: December 2020

Purpose: The aim of the paper is to present the scope of environmental information disclosed by organi-zations from the healthcare services sector in Europe. Methodology/approach: The aim was achieved by studying the GRI Sustainability Disclosure Database, where non-financial reports are published, and performing a content analysis. The research sample con-tains 252 reports issued by 65 healthcare organizations between 2001 and 2019. Findings: The research results indicate that information concerning energy is disclosed most frequently – in 213 reports (95%). In 194 non-financial reports (86%), organizations inform about healthcare waste. The third and fourth main environmental issues are water and effluents (168 reports – 75%), and emis-sions (166 reports – 74%). Information related to materials is included in 134 sustainability reports (60%) and environmental compliance in 125 reports (56%). Biodiversity (60 reports – 27%) and supplier envi-ronmental assessment (51 reports – 23%) are disclosed least frequently. Research implications/limitations: The paper presents a complete picture of environmental disclosure practices in the European healthcare services sector in the past 20 years and offers interesting insights into non-financial reports, which are the most common instruments used by organizations to provide account-ability about their environmental performance. However, there are some limitations – the GRI Sustaina-bility Disclosure Database does not include all reports produced by European healthcare organizations. Originality/value: This research contributes to the growing literature on sustainability reporting in the healthcare services sector by providing an empirical view of its current state in Europe. It fills a research gap in the field of non-financial reporting practices of healthcare organizations.

Os índios de Pedra Branca-Bahia (1825-1889): uma história de conflitos e resistência em defesa da terra indígena
Authors: Ribeiro Edilmar Cardoso
Published: December 2020

A história da vila (municipalidade) e depois aldeamento de Pedra Branca (1822-1890), atual povoado de Pedra Branca, localizado no município de Santa Teresinha-Bahia, foi marcada por conflitos entre indígenas, autoridades públicas e colonos locais. Os indígenas de Pedra Branca frente ao processo de exclusão da participação da administração pública da vila e, principalmente, frente ao processo de usurpação das terras indígenas, isto é, de uma légua e meia de terra que os indígenas diziam ter herdada dos seus antepassados e, por isso, de ser os legítimos donos. As formas de resistências dos índios frente a esse processo: a ocupação dos cargos de vereadores e juízes como uma forma de controlar a administração da terra indígena e garantir sua posse, as negociações com as autoridades não indígenas, a insubordinação às autoridades constituídas não indígenas, e as revoltas. As medidas das autoridades públicas não indígenas (vereadores, diretores de índios, delegados, juízes, militares, vigários, missionários) para controlar e enquadrar os indígenas dentro de uma ordem: as negociações, a diretoria dos índios, o diretor missionário e as expedições militares. O resultado deste processo conflituoso foi: a extinção da municipalidade e do aldeamento, a invasão das terras por posseiros e a dispersão dos indígenas.

Remote Sensing Applications in Disease Mapping
Authors: Nick Dlamini Sabelo
Published: December 2020

Disease mapping utilizes disease maps as visual representations of sophisticated geographic data that provide a general overview of the disease situation in a defined geographic area. Epidemiology is concerned with investigating the causes of diseases, and often, these causes vary in frequency and in space. This variation in space gave a niche to remote sensing to find its way into the public health domain as disease researchers sought to investigate the explaining environmental and climatic factors. Studies have demonstrated the potential offered by remote sensing application to disease mapping and epidemiology and to support surveillance and control efforts. We used some examples from a case study conducted in Eswatini in Southern Africa. Remote sensing imagery when combined with GIS spatial analyses techniques could support and guide existing disease surveillance and control programs at local, regional, and even continental scales. Researchers have also studied factors influencing the patterns and distributions of vector-borne diseases at a variety of landscape scales. However, successful application of remote sensing technology depends on the ability of nonexperts’ remotely sensed data and end users to access, retrieve, and analyze the data captured from satellites. The exploration of some of the opportunities presented by remote sensing to disease mapping and epidemiology is still unfolding as new opportunities are being presented.
Juvenile Delinquency between Probation and Criminal Careers

Published: December 2020

The focus of the criminological research is on probation and diversion measures applied in metropolitan judicial districts where juvenile deviance and criminal careers are frequent. Presidential Decree 448/1988 measures application in Naples judicial discrict reflects the “juvenile probation “ in juvenile ligislation, the problems of the local and urban organized crime context and the lack of penal welfare. The sources of analysis are an experimental sample of minors holders of the probation measure from Juvenile Court’s files, three other control sample holding diversion or conviction, the examination of the recidivism rate and criminal relaspe. Both database of the General Criminal Records and the Department of Prison Administration were consulted to monitor further sub-objectives and measures the recidivism rates. The results of the research highlight the risk assessment linked to the path of deviance according to the performance of the child recovery activities implemented by the host and penal communities. Evaluations acquires even more importance if observed after the entry into force of the Law of 28 April 2014 no. 67 introducing in the criminal code and criminal procedure, both the suspension of the trial and the provisions on non-punishment for particular tenuity of the fact (Legislative Decree 16 March 2015 n. 28).
Resilient Health System and Hospital Disaster Planning
Authors: C. Morris Stephen
Published: December 2020

Disaster planning is integral component of hospital operations and management, and hospital resiliency is critical to society and health systems following a disaster. Additionally, hospitals, like all public institutions have significant risk of security incidents including terrorism, isolated and mass violence, social unrest, theft and vandalism, natural and human made disasters. Security and disaster planning are cumbersome, expensive and easy to deprioritize. When a hospital disaster is defined as anything that exceeds the limits of the facility to function at baseline, disasters and security incidents are intertwined: disasters create security problems and vice-versa. Hospital resiliency to disasters and security incidents stems from a systems-based approach, departmental and administrative participation, financial investment and flexibility. Significant best practices and lessons learned exist regarding disaster and security planning and ignorance or lack of adoption is tantamount to dereliction of duty on the part of responsible entities. This chapter consists of a review of the concepts of hospital disaster and security planning, response and recovery, as well as hospital specific disaster and security threats (risk) and their associated mitigations strategies. Risks will be presented follow a hazard vulnerability analysis (HVA), a common framework in emergency management, disaster planning and disaster medicine. As such, each element of risk is defined in terms of likelihood and impact of an event. Concepts of disaster medicine that are also addressed, as are administrative concerns, these elements are designed to be applicable to non-experts with an emphasis on cross disciplinary understanding. Additionally, elements are presented using incident and hospital incident command terminology and those not familiar should learn these concepts though free online training on the incident command system provided by several sources including The United States Federal Emergency Management Agency (FEMA), prior to reading.
Cell Interaction and Mechanobiological Modeling of Bone Remodeling Process
Authors: Ben Kahla Rabeb , Barkaoui Abdelwahed , Zohra Ben Salah Fatma , Chafra Moez
Published: December 2020

According to the structural and metabolic demands of the body, proportionate and accurate bone quantities are resorbed and formed, establishing what is known as bone remodeling process. This physiological process requires a highly coordinated regulation through a complex interconnected network involving several cells from diverse origins, in addition to various hormones, cytokines, growth factors and signaling pathways. One of the main factors initiating the remodeling process is the mechanotransduction mechanism, through which osteocytes translate the mechanical stimuli subjected to the bone into biochemical signals, generating thereby the activation of osteoclasts and osteoblasts that govern bone resorption and formation. This mechanically-induced behavior of bone tissue has been the target of computational modeling and numerical simulations, to address biomechanical questions and provide information that is not amenable to direct measurements. In this context, the current chapter aims to review the coupling and mechanotransduction mechanisms spearheading the remodeling process, in addition to the main mathematical models developed over recent years and their use in bone numerical simulations based on the finite element method.
Comparative Effects of Total Intravenous Anesthesia with Propofol and Remifentanil Versus Inhalational Sevoflurane with Dexmedetomidine on Emergence Delirium in Children Undergoing Strabismus Surgery
Authors: Oriby Mohamed E , Elrashidy Ayman
Published: December 2020

Background: Emergence delirium (ED) is common after strabismus surgery due to postoperative visual disturbance, vomiting, and pain. Total intravenous anesthesia (TIVA) has many advantages like smooth emergence from anesthesia, decreased incidence of postoperative nausea and vomiting (PONV), and postoperative analgesia. Objectives: Our study aimed to compare the incidence of ED using inhalational sevoflurane with dexmedetomidine (DEX) versus TIVA with remifentanil. Methods: Eighty-four patients aged 3 - 11 years scheduled for strabismus surgery under general anesthesia were randomly allocated into two groups. Patients in group I received sevoflurane and DEX (group I, n = 42), while group II patients received TIVA with propofol and remifentanil infusion (group II, n = 42). Mean arterial pressure (MAP), heart rate (HR), and pulse oximetry (SpO2) were monitored before induction, at induction, and every 10 minutes during the surgery. In the postanesthetic care unit (PACU), pediatric anesthesia emergence delirium (PAED), face, legs, activity, cry, and consolability (FLACC), need for rescue analgesics, recovery time, level of parents’ satisfaction, and PONV were recorded. Results: Based on the results, HR and MAP significantly decreased 10 and 20 min after induction compared to baseline in group I after infusion of DEX. The incidence of PONV was significantly lower in group II than in group I, while the recovery time was significantly shorter in group I. The incidence of emergence delirium decreased in both groups. Conclusions: The use of either total intravenous anesthesia with propofol and remifentanil or sevoflurane inhalational anesthesia with dexmedetomidine resulted in a lower incidence of emergence delirium, although dexmedetomidine resulted in hypotension, bradycardia, and PONV.
Comparison of the Effectiveness of Nursing Consultation and Guided Imagery-Based Training on Stress and Anxiety in Angiography Candidates: A Clinical Trial
Authors: Nikfarjam Malihe , Firouzkouhi Mohammadreza , Shahdadi Hossein , Abdollahimohammad Abdolghani
Published: December 2020

Background: Despite the use of various pharmacological and non-pharmacological methods for reducing stress among patients, one of the most important nursing challenges is how to control anxiety and stress in patients undergoing coronary angiography. Objectives: The present study aimed to compare the effectiveness of nursing consultation and guided imagery-based training on the level of stress and anxiety in patients undergoing coronary angiography. Methods: The participants in this clinical trial included 60 angiography candidates, admitted to the coronary care unit (CCU) of Ali-Ibn Abi-Taleb Hospital in Zahedan, southeast of Iran, in 2019. The participants were selected using convenience sampling and randomly assigned to three groups: nursing consultation, guided imagery, and control groups. The instruments used to collect the data included a demographic information form and the Depression, Anxiety, and Stress scale (DASS-21). The questionnaires were completed by the participants in all three groups on the day of hospitalization and one hour before angiography. A guided imagery audio file was played one day before angiography for each participant in the nursing consultation group for a maximum of two hours. On the other hand, the guided imagery group, besides receiving routine care, listened to the same audio file for 30 - 45 minutes. However, the participants in the control group only received routine hospital training. The collected data were analyzed in SPSS version 25, using statistical tests, such as analysis of variance (ANOVA), Tukey’s post hoc test, analysis of covariance (ANCOVA), paired samples t-test, Fisher’s exact test, and chi-square test at a significance level of less than 0.05 (P < 0.05). Results: After controlling for the significant effect of pretest scores, the results of ANCOVA test showed significant differences between the two intervention groups in terms of the mean scores of anxiety and stress after the intervention (P < 0.001). Also, the mean scores of anxiety and stress decreased in the guided imagery and nursing consultation groups as compared to the control group. However, the two interventions were not significantly different in reducing anxiety and stress among patients undergoing coronary angiography (P = 1). Conclusions: In this study, nursing consultation and guided imagery interventions led to a reduction in the stress and anxiety of patients undergoing angiography. Although the two interventions showed no significant difference in terms of effectiveness, they had positive effects on the mental health of angiography candidates. Therefore, these techniques can be employed by nurses, depending on their ease of use and conditions, to reduce stress and anxiety among angiography candidates.

Published: December 2020

Objectives:Interpersonal influence and word-of-mouth communication represent the most important sources of information used in the purchase decision process. This form of communication has a special role and importance in tourism due to the intangible nature of products offered in this market. With the advancement in information technologies an increasing number of consumers - users of tourist services use the Internet to obtain information about a tourist destination and, at the same time, share their experiences with other consumers. In this way online interpersonal influence and electronic word-of-mouth communication are realized. The aim of this paper is to examine whether there are any significant differences in the electronic word-of-mouth effects and generation by consumers - users of tourist services in relation to their socio-demographic characteristics (gender, age, and education). Methodology: The sample included 228 respondents from the province of Vojvodina. The method of cross-tabulation was applied in order to test the hypotheses. Implications/results: Survey results provide tourism marketers with a more detailed insight into the behavior of users of tourist services with respect to their socio-demographic characteristics. Contribution: This paper contributes to further theoretical elaboration of the current phenomenon of electronic word-ofmouth in terms of explaining it through the prism of causes and effects.
Customs War of the Kingdom of Serbia and the Habzburg Monarchy at the beginning of the 20th century

Published: December 2020

After gaining independence at the Berlin Congress, Serbia became the center around which all the surrounding Serbs gathered, seeking final liberation and unification. The great difficulty for a small Serbia was the Austro-Hungarian Empire, which in every way was trying to influence the Serbian internal and foreign policy. In doing so, she succeeded to a large extent during the reign of King Milan, even after his abdication, until the beginning of the XX century. The change in the throne after the May uprising led to the emancipation of Serbia from the influence of the Austro-Hungarian Empire and the influence of other powers, in particular France and Russia. On the other hand, Serbia is increasingly independent in foreign policy and tries to connect with other Balkan states as if it economically strengthens to carry out a national unification mission. That is why the Austro-Hungarian conflict with Serbia on the economic plane, the Customs War, was inevitable. At the same time, this conflict has shown the strength and weaknesses of both countries. Serbia's victory in the Customs War showed her great economic rise, and Austro-Hungary became its fatal enemy.

Published: December 2020

Different types of interactions between rural and urban areas have the effect of improving economic, social, cultural and political dimensions in both areas, separating these two areas by their type of activity. Rural and urban types of regions have different resources and means that can be used in a complementary way. In rural-urban interaction there is a possibility of occurrence of conflict of interest of these two areas. This kind of conflict should be overcome when applying the partnership approach between rural and urban areas. The types of rural areas, depending on the proximity of the urban center and the functions of these areas, are divided into suburban, agricultural and remote type areas. By determining the functions of each type of area, the type and intensity of the interactions of rural areas with the urban center are presented. Rural entrepreneurs are able to bridge rural-urban differences, possessing certain market knowledge and descriptions of the characteristics of urban environments, while benefiting from their position. Rural entrepreneurs' interaction with the urban environment can contribute to sustainable economic relations between citizens in urban and rural areas. This paper presents the results of research related to determining the functions of certain areas, their strengths, unused and utilized resources, the frequency of interaction with the urban environment and the perspectives of suburban, agricultural and remote type areas in the context of interaction with the urban environment.

Based on current data and documents available from relevant statistical organizations, this paper presents and analyzes statistical and economic indicators of software product development in Serbia, with a parallel review of adequate data for the European Union. A descriptive method for comparative analysis was used for the analysis of data related to the number of enterprises, number of employees, average realized earnings per employee, and the realized turnover in Telecommunications, Computer programming, and Information sectors. Due to considerable differences in terms of areas that countries cover and the strength of their economies, trends in the mentioned areas and monitored and analyzed parameters (e.g. employment, average earnings and total exports, i.e. turnover of services) were observed. The obtained results indicate that Serbia has exceptional potential in the field of computer programming, while other activities in the field of information dissemination and communication, for now, do not record significant growth. On the other hand, in the European Union, the analyzed areas show stability of the analyzed parameters in the observed period. This indicates that a high level of development has been reached in the EU and that significant progress is now being made more slowly. With this development trend, the field of computer programming will probably be the first economic area in which Serbia can catch up with the European level.
Experimental studies of robotic assembly of precision parts
Authors: Polishchuk Mikhail , Tkach M.
Published: December 2020

At present, robotization of assembly processes is achieved through the use of industrial robots with high positioning accuracy in conjunction with tactile means of adaptation to the conditions of assembly of precision parts. The cost of such robots is many times higher than the cost of simple robots with low positioning accuracy of the robot arm. The research in this article is aimed at reducing the cost of assembly processes for precision parts by applying the position correction of the connected parts not by the robot hand, but by an additional technological module that is installed on the manipulator of a simple robot and performs high-speed stochastic mismatch scan of assembly objects. The article presents the results of a full factorial experiment of the process of joining precision cylindrical parts with a gap of no more than 3...5 microns. A regression model of this process is proposed, a formula for calculating the quasi-optimal modes of precision assembly and graphanalytical dependences of the assembly time on the scanning modes of the misalignment of assembly objects are given. The proposed high-speed method for compensating for the positioning error of an industrial robot makes it possible to assemble precision parts in a very short time within 1...3(s). The main economic effect of the research results is that the device for scanning the misalignment of assembly objects, which is installed on the arm of an inexpensive robot with a low positioning accuracy, can significantly increase the assembly speed and reduce capital investments in robotic assembly of high-precision parts.
Experimental analysis on friction stir welding using flat-faced pins in AA2024-T3 plate

Published: December 2020

In friction stir welding, lesser tool life restricts the usage of non-circular pin in friction stir welding tool eventhough it delivers comparatively better weld joints than circular pin. Process peak temperature during the process affects the shear strength of the flowing material around the tool pin. Maintaining the process peak temperature as low as possible improves the properties in heat affected zone but on the other hand it increases the stress on the tool pin.Especially on the usage of non-circular pin, the pin surface experiences uneven stress distribution and causes premature tool failure. In this paper, optimum thermal environment through proper selection of process parameters and dwell period with respect to the pin geometry are analysed. A comparative analysis is also made to understand the impact of increase in flat surfaces in the pin surface on weld quality in the view of developing a suitable thermal environment that can improve tool life without compromising joint strength. Apart from this, optimum dwell period for the chosen tool pin geometry is analysed based on the empirical softening temperature of the material.
Experimental studies on the effect of shunted electrical loads on the performance of a vibration-based electromagnetic energy harvester
Authors: Patil Vijay , Sakri Mahadev
Published: December 2020

At present, the researchers are grappling with the problems of maximizing the output power from a vibration-based electromagnetic energy harvester (VBEH). The parameters affecting the VBEH output power are: electrical damping ratio (ze), mechanical damping ratio (zm) and load impedances of shunted electrical load. Therefore, in this work, the experimental studies are carried out to study the effect of shunted electrical load on: i) the power output of VBEH and, ii) the determination of ze which maximizes the output power. For this purpose, a VBEH is designed and developed to obtain high open-circuit voltage. The effect of resistive, inductive, and capacitive loads on output power of VBEH is investigated using experimental setup developed exclusively for the same. The experimental results reveal that the output power of VBEH is maximum: i) at the resonant frequency ii) when equivalent resistive load impedance equals the internal resistance of electromagnetic coil and iii) value of ze is very small when compared to zm.
Production-time evaluation technique for small manufacturing plants

Published: December 2020

Small manufacturing plants usually experience challenges of inefficiency and low production yields. These problems have previously been addressed using methods to redesign plant layouts and reduce distance between workstations. Furthermore, assessment techniques like the machine-distance matrix method have then been required to evaluate layout performance. However, these assessments that rely only on distance evaluation are severely limited. In this paper, a new model called Production-time evaluation is presented for evaluating production layout efficiency. It involves computing the estimated time for production at workstations, time for movement between workstations and number of units of a product manufactured. It is then applied on a case study in small furniture plant. The existing layout of the plant was extracted and the production processes for its three products were outlined. A new layout was designed and both layouts were compared using the Production-time methodology, revealing improvements in reduced production time and increased daily production capacity by up to 37% for a product.

This research paper presents hardness, structure and tensile strength analysis of 1460 alloy of Al-Cu-Li system, welded joints made by Tungsten Inert Gas (TIG) welding and Friction Stir Welding (FSW). Characteristics of acoustic noise at the welding operator workplace during mechanized TIG and FSW of aluminium-lithium alloy with the purpose to develop recommendations for the improvement of health and safety during welding processes were studied. Analyzing results, we concluded that during TIG welding the values of welding noise at the workplace, are much higher than the admissible noise level limit. Results showed that the values of the welding nose reach 95 dB. The noise level at the workplace for FSW is also dangerous and reaches up a value of 84.3 dB. Also, this paper presents hardness, structure, and tensile strength measurements of 1460 alloy welded joints made by TIG and FSW welding.
Dictionary article as text in lexicology instruction
Authors: Milosavljević Bojana
Published: December 2020

The paper presents the possibilities of using dictionary articles from our descriptive monolingual dictionaries as texts for teaching lexicology at academic courses of teacher training faculties. The starting point of the paper is that literary texts are traditionally used in teaching languages, while other types of texts (non-literary texts) are less frequently used, which, in turn, affects students' reading literacy. The main part of the paper focuses on the qualitative analysis of the selected dictionary articles from our descriptive monolingual dictionaries, with a special emphasis on using a dictionary article in teaching lexicology as an 1) introductory text, 2) text used for identifying lexical phenomena, 3) text used for practising lexical phenomena, and 4) text as a part of the knowledge assessment test. Based on our analysis, we concluded that using dictionary articles in teaching lexicology may entail multiple benefits - acquiring the knowledge of lexicology, enriching one's vocabulary, developing language culture, but also developing lexicological knowledge, skills, and habits, which fosters preservice primary school teachers' functional literacy.
