Authors: Abdrashitov Alexey , Marfin Evgeny , Plekhova Ekaterina
Published: May 2021

Experimental studies the model of a jet-driven Helmholtz oscillator has been carried out. The oscillator is a cylindrical chamber,
closed on the sides by two covers with inlet and outlet holes. The oscillator was excited by a stream of airflow. The influence of the
geometric dimensions of the chamber and the openings in the covers on the amplitude of pressure fluctuations was studied and the
optimal channel configuration was determined. Particular attention is paid to the study of the influence on the amplitude of pressure
fluctuations of the shape and size of the nozzle - the hole in the front cover. There were measured the following processes: the pressure
drop across the nozzle, to calculate the speed of the jet at the chamber entrance, and the parameters of pressure fluctuations in
the chamber, to plot the amplitude-frequency spectra. There were made certain observations of a jet tone appearance and acoustic
modes excitation at the natural frequency of the chamber-resonator with a smooth increase in the jet velocity. The relationship between
the jet tone and the resonant in the chamber is noted. Recommendations for designing a Helmholtz jet oscillator are presented.

Published: May 2021

The rail transport (railway lines, shallow subway lines or passing on the surface) is a source of increased vibration.As a result,
predicting the parameters of vibration and the structure-borne noise generated by it when designing residential and public buildings
near lines or designing new transport lines is an important task. For operating lines, the initial data for the forecast are the results of
measurements of vibration parameters at the location of the projected building. For projected lines, the parameters characterizing the
source of vibration - the vibration characteristics of moving trains - should be used as the initial data for the forecast. The method for
railway trains vibration characteristics determination is described which based on field measurements. As an example of the method
application determination of vibration characteristicsof suburban electric trains running along the line of the Savelovsky direction of
the Moscow railway is sited. Linear regressions equations are given that connect the weighted vibration velocities in the horizontal
direction of vibration propagation perpendicular to the railway line with the train speed

Authors: Solovieva Olga , Elkin Yuri
Published: May 2021

An article discusses the problem of noise reduction in a residential area located in the immediate vicinity of construction
sites. Since construction sites are often located at a short distance from existing residential buildings, it will be ineffective to install
only a conventional noise barrier - walls. In this regard, we have developed a classification of shielding noise protection structures for
construction sites, the complex application of which will make it possible to achieve standard noise levels in the adjacent residential
area. The article presents the efficiency calculation and designs of two screens (perimeter and intra-sectoral) of five indicated in classification
types.
ON CONTROL OF A PRESSING FORCE APPLIED TO ACOUSTIC LINER SAMPLE IN A NORMAL INCIDENCE IMPEDANCE TUBE
Authors: Kustov Oleg , Palchikovskiy Vadim , Khramtsov Igor , Bulbovich Roman
Published: May 2021

The study considers the influence of control of the pressing force applied to an acoustic liner sample in a normal incidence
impedance tube on the spread of acoustic characteristics of the tested sample. The design of a normal incidence impedance tube with
a control system of a sample pressing force is presented. This system is implemented as a piston in a pneumatic cylinder with a pressure
control unit. The measurements were taken on days when the characteristics of the environment were different from each other.
This made it possible to better track the influence of the pressing force on reducing the spread of acoustic characteristics. In total, 10
measurements of the acoustic liner sample were carried out on a normal incidence impedance tube with and without control of the
pressing force. The measurements were carried out for six months. As a result, the study has shown that the control of the pressing force
applied to the acoustic liner sample provides a smaller spread of the obtained acoustic characteristics.

ACOUSTICALLY CHARACTERIZED 'EXPERIENCE OF TRANSCENDENCE' IN PFARKIRCHE ST MICHAEL, STEYR
Authors: Tavares Menino Allan S.M. Peter
Published: May 2021

Experience of Transcendence’ is acoustically characterized in Pfarrkirche St Michael, Steyr using trained participants’ feedback during live organ rendition of Johann Sebastian Bach’s ‘TOCCATA’. Transcendental experiences of ‘awe’, ‘deeper understanding’ and ‘tranquility’ were acoustically derived and termed as ‘Acoustically Transcendent Awe’ (ATAWE), ‘Acoustically Transcendent Intelligibility’ (ATINT), and ‘Acoustically Transcendent Tranquility’ (ATTRANQ). In this study, ‘Acoustically Transcendent Intelligibility’ (ATINT) and ‘Acoustically Transcendent Tranquility’ (ATTRANQ) showed significant multiregressions with subjective acoustical qualities of the space (R2=0.99; p=0.01) and (R2=0.99; p=0.04) respectively. Instantaneous, statistical and percentile sound levels during ambient noise and during live performances were recorded at different listening zones. Background Noise Levels (LA90) between 76dB-82dB indicated congregational and choir space as optimally loud (without any need for electro-acoustical support) and sanctuary (with LA90 value
of 56.8dB) as needing support, for performance and listening. Acoustically ranscendent Intelligibility (ATINT) was found significantly predictable from Subjective Acoustical Quality of Silence from Background Noise (SAQSNOIS) (p=0.05) and from Background Noise Level (LA90) (p=0.05). Perception of optimal Reverberance (SAQREV) in the Choir Loft provides good ambience for choir and musicians. These significant relationships between Acoustical Transcendence Impressions, Subjective Acoustical Qualities and Sound Levels can serve as part of Pfarrkirche St Michael’s unique intangible heritage.

Improving Sustainable Development of Eco-Tourism in Kenya
Authors: Ogweno Edwin Otieno
Published: May 2021

Eco-tourism is generally defined as the type of tourism that involves visiting a natural environment without interfering with its habitat. The tourism industry is a multibillion-dollar industry that continues to expand and evolve around the world, however, to achieve sustainable growth, it requires a shift in planning and as a result, more focus on eco-tourism. When thinking of tourism, one thinks of a certain group of people visiting a particular destination for sightseeing, holiday vacations, and to have a good time; while that could be true, tourism touches on more than that. The tourism sector, besides just the gratification and exchange of culture, also involves environmental aspects, social aspects, and sustainability. As the world strives to achieve long-term growth targets in the sustainable development goals, eco-tourism continues to receive much attention. Eco tourism has been related to programs for sustainable development in protected areas, community-based conservation organizations, and in many aspects aimed at achieving sustainable development goals on environmental and habitat protection. In order to sustainably improve the eco-tourism sector, there is a need for continuous education, a supportive policy environment, and more research on the sector

Authors: SKAČKAUSKIENĖ Ilona , BUSARĖVA Anastasija
Published: May 2021

Purpose – to evaluate the efficiency of the credit provision process of Lithuanian banks, to submit suggestions
for improvement.
Research methodology – after the theoretical analysis of the efficiency of the credit granting process was developed,
an empirical research using the methods of questionnaire survey and analysis of financial indicators was carried out.
Findings – efficiency is usually lost at the stages of consideration of application, conclusion of credit portfolio and
risk assessment. These factors were distinguished from all efficiency reducing factors: time consuming processes, not
automatized stages, insufficiently informed customer.
Research limitations – methods of analysis of scientific literature are limited, but they enable the analysis and identifi-
cation of the efficiency of credit provision within the research.
Practical implications – the article evaluates the efficiency of credit provision by selected banks and proposes measures
to streamline the process. By applying the proposed measures, banks could increase the efficiency of the credit granting
process.
Originality/Value – previously, the effectiveness of credit granting process in Lithuanian banks has not been assessed.
MODEL FOR SOCIAL MARKETING IMPACT ON CONSUMERS HEALTHY LIFESTYLE CHOICE
Authors: STATNICKAITĖ Justė , PAULĖ Monika
Published: May 2021

Purpose – the purpose of this article is to present the novel model developed to measure social marketing impact on consumers choice for healthy lifestyle. Social marketing is very complex by aiming to promote socially responsible products and behavior for the benefit of the consumer and society at the same time. What is more, con- sumers choice for healthy lifestyle is determined not only by marketing influence but other personality and external environment factors as well. Research methodology – the model presented in the article was developed based on literature analysis and secondary data. Findings – social marketing impact on consumers choice for healthy lifestyle is determined not only by the social mar- keting, but also the consumer personality itself and the influence of the external environment on consumer. Research limitations – validation of the novel developed model dedicated for the measurement of social marketing impact on consumers choice for healthy lifestyle should be further validated with quantitative research methods. Practical implications – the application of the model will enable marketing specialists to determine the contents and other situational details of social marketing for consumers to choose healthy lifestyle and products related to it. Originality/Value – the value of the model is determined by its novel attitude to social marketing in parallel with other factors affecting consumer behaviour.

Authors: BAVIERA-PUIG Amparo , ESCRIBÁ-PÉREZ Carmen , MONTERO-VICENTE Luis
Published: May 2021

Purpose – to analyze the image, consumption and purchase habits of chicken and turkey meats by households
with children as both kinds of meat are healthier than others.
Research methodology – in the field of marketing, we carried out a telephone survey, a tool commonly used in market
research to obtain primary source information.
Findings – there are differences between households with and without children under 18 years old in the consumption
and purchase habits of turkey and chicken meat. Instead, there is no difference in the image of both meats between the
total of the sample and the households with children under 18 years old.
Research limitations – we have not analysed the performance of these meats in relation to other types of meat. There-
fore, it would be useful to have data on other meats in the future in order to make comparisons.
Practical implications – the results of the research can be used to develop appropriate social responsibility strategies
in the meat industry.
Originality/Value – the point of view we provide is novel as we have not found comparable studies for these types of
meat. Previously, the authors have analysed the children’s consumption of rabbit meat using a similar approach.

Authors: DOAN Mai Thi , DUKHNO Sergey I.
Published: May 2021

Purpose – to identify the prerequisites for organizational changes of the emerging health insurance system
in Vietnam.
Research methodology - comparative analysis, statistical analysis, case study.
Findings – the obligatory health insurance in Vietnam performs its functions only partially. There is still high level
of out-of-pocket spending on medical services. First we identified one of the most important challenges to the health
insurance system in Vietnam, namely, the population aging. Secondly, we identified and analyzed and the prerequisites
(the pre-existing conditions), which can become the basis for the reorganization of the existing health insurance system
without major reforms: (1) the cultural values of Asian society, which allow to build a community-based type model of
living for the elderly on the basis of “equal with equal”; (2) technological advances in medicine that extend the healthy
life of the elderly, (3) trust in traditional medicine, which allows widen the coverage of the poorest “elderly households”.
Practical implications - the results of the study require attention from the government and insurance providers when
rethinking of organizing process for mandatory medical insurance.
Originality/Value – we have identified the ways of possible organizational changes for the health insurance system,
making the most of the existing prerequisites. This can help to get closer to the goal of full coverage with health
insurance services while achieving a positive social effect. The identified internal reserves make it possible to imple-
ment organizational changes without major reforms of the established health insurance system. No studies have been
conducted in this perspective.

human capital to achieve sustainable development and competitive advantage.
WHAT ARE IDEAS MADE OF? ON THE SOCIO-MATERIALITY OF CREATIVE PROCESSES
Authors: Rudnicki Seweryn
Published: May 2021

This article explores the possibility that ideas are dynamic, socio-material and relational entities that come into existence with the help of materials and technologies. It starts from arguing that the popular understanding of ideas as immaterial entities (thoughts, concepts, insights) that we process mentally, communicate (symbolically) to others, and eventually realise is rooted in essentialist and representationalist philosophy and as such is not universal. It is then argued that an alternative understanding of what an idea is may be proposed within the relationist perspective that focuses our attention primarily on change and historicity. The article employs the concept of translation – borrowed from the actor-network theory – to propose that an idea is enacted slightly differently in every social situation and with the use of different materials and technologies. Importantly, the presented relational and socio-material interpretation emphasizes that it is not the “essence” of an idea but the translations it is subjected to that enable or constrain action possibilities and determine its evolution. Finally, it is proposed that following translations of ideas empirically may be a promising avenue for further research.

The heavy metals contamination in soil has attracted increasing attention. In this study, the main objective was to determine three heavy metals (Cd, Pb, and Cr) of soils contaminated by smelting waste, and to evaluate pollution risk. The Pb (15.48 mg/kg) and Cd (311.39 mg/kg) mean concentrations exceeded the national standard, while Cr (48.60 mg/kg) concentration did not exceed. The Heavy metal fractions analysis showed that three heavy metals were dominated by FeMn oxides fraction (Fe-Mn). The correlation and cluster analysis indicated that there was significant correlation between Cd and Pb (0.55< r < 0.96), while Cr was not correlation to Cd and Pb. The environmental pollution of heavy metals was assessed by the ratio of secondary phase and primary phase (RSP). The result showed that RSP values of Cd, Pb, and Cr range from 13.05–54.28, 16.11–4.97 and 1.61–52.33, which indicated soil was serious contaminated by them. These results showed that smelting waste discharge led to this smelter soil being seriously contaminated by multiple heavy metals which have a tendency to transport and accumulate into deep soil due to their high fractional transformation.
TREATMENT OF ELECTRIC VEHICLE BATTERY WASTE IN CHINA: A REVIEW OF EXISTING POLICIES
Authors: Li Wenbo , Yang Muyi , Long Ruyin , Mamaril Kristy , Chi Yuanying
Published: May 2021

This paper reviews existing policies for supporting the treatment of electric vehicle (EV) battery waste in China, and identifies some of their major shortcomings that policy makers may like to consider while making policy decisions. The shortcomings of existing policies identified in this paper include: 1) no clear provisions for historical and orphan batteries; 2) no target for battery collection; 3) unclear definition of the scope of authority among various central and local agencies involved in the regulation of waste battery treatment; 4) unclear requirements for data auditing and verification for tracking the entire life cycle of EV batteries; 5) limited consideration of the challenges to ensure stakeholder cooperation; and 6) no explicit specification of the mechanisms for financing waste battery treatment. This paper also makes some practical policy suggestions for overcoming these shortcomings.

Jupiter-family comets (JFCs) contribute a significant amount of debris to near-Earth space. However, telescopic observations of these objects seem to suggest that they have short physical lifetimes. If this is true, the material generated will also be short-lived, but fireball observation networks still detect material on cometary orbits. This study examines centimeter-to-meter-scale sporadic meteoroids detected by the Desert Fireball Network from 2014 to 2020 originating from JFC-like orbits. Analyzing each event’s dynamic history and physical characteristics, we confidently determined whether they originated from the main asteroid belt or the trans-Neptunian region. Our results indicate that <4% of sporadic meteoroids on JFC-like orbits are genetically cometary. This observation is statistically significant and shows that cometary material is too friable to survive in near-Earth space. Even when considering shower contributions, meteoroids on JFC-like orbits are primarily from the main belt. Thus, the presence of genuine cometary meteorites in terrestrial collections is highly unlikely.
Redescription of Gnorimosphaeroma oregonense (Dana, 1853) (Crustacea, Isopoda, Sphaeromatidae), designation of neotype, and 16S-rDNA molecular phylogeny of the north-eastern Pacific species
Authors: Wetzer Regina , Wall Adam , Bruce Niel L.
Published: May 2021

Gnorimosphaeroma oregonense(Dana, 1852) is revised, a male neotype is designated, photographed, and illustrated; the species occurs from Vancouver British Columbia to the central California coast. 16S-rDNA sequences (~650 bp) for all available ethanol preserved species ofGnorimosphaeromawere used to hypothesize their relationships. Our analyses revealed a sister taxon relationship between the fully marineG. oregonenseand the brackish to freshwater species,G. noblei. The oyster associated and introducedG. rayiis sister to a previously not recognized or identified, but genetically distinct,Gnorimosphaeromasp. collected at two sites in San Francisco Bay.Gnorimosphaeromasp. is probably also a western Pacific species based on its genetic relationship toG. rayi. Photographic comparisons are offered forG. oregonense(marine),G. noblei(freshwater),G. rayi(introduced),G.sp. (presumably introduced), andG. insulare(San Nicolas Island). Records of the holdings at the Los Angeles County Museum of Natural History are summarized. Without material available north of Vancouver through Alaska, the range ofG. oregonensecould not be genetically verified. This review includes a diagnosis and description of the genusGnorimosphaeromaMenzies, 1954.

La función apodótica de la conjunción e en las biblias medievales hispánicas
Authors: Garrido Sepúlveda Claudio
Published: May 2021

En el siguiente trabajo, estudiamos la función apodótica de la conjunción e en la lengua de las traducciones medievales de la Biblia hebrea. Esta partícula ha sido reconocida como una transliteración o calco del waw apodótico del hebreo y actúa como refuerzo en la apódosis de algunas oraciones bipolares como la estructura condicional. Nuestro propósito es aportar datos objetivos en relación con las biblias y los contextos discursivos más sensibles a la transliteración de esta regla idiomática. Además, efectuamos contrastes con datos provenientes de traducciones medievales de la Vulgata y con traducciones del siglo xvi —la Biblia del Oso y la Biblia de Ferrara—. En suma, el análisis nos conduce a matizar la idea de que la presencia de la conjunción e en apódosis condicionales responde a un mero ejercicio de calco idiomático.

D’infirmière vers professeur des écoles : reconversion professionnelle et identité personnelle
Authors: Guillot Agnès , Lanoë Soazig
Published: May 2021

Un quart des infirmières étant touchées par l’épuisement professionnel, départs et reconversions volontaires ne se font pas rares, bien que peu observés dans ce champ professionnel. L’étude monographique et l’analyse de carrière d’une infirmière hospitalière devenue professeure des écoles nous a permis de comprendre sa dynamique de passage d’un métier à l’autre, recomposant son identité professionnelle dans l’appui sur des valeurs éminemment personnelles. La mise à l’épreuve de son sentiment capacitaire l’a décidée à s’engager dans une bifurcation professionnelle volontaire, son estime de soi étant entamée par l’usure professionnelle et la confrontation à la mort de ses patients. Elle a su reconquérir l’un et l’autre et nous révéler des compétences hospitalières réinvesties comme enseignante, métier qu’elle aborde ordinairement et singulièrement, relançant la question de la gestion du bruit dans la classe. Soutenue par son institution d’origine et un « autrui significatif », elle a préparé son projet de reconversion professionnelle et y est entrée en restant fidèle à ses identifications et à elle-même. Cette étude, fondée sur une démarche ascendante d’analyse croisée de corpus, à travers entretiens cliniques et questionnaires d’analyse de carrière, s’est centrée sur l’activité première d’infirmière et ses contraintes, la prise de décision d’une reconversion vers l’enseignement et ses conditions, ainsi que sur les étapes de cette bifurcation volontaire.
Situation d’apprentissage et conceptualisation
Authors: Pastré Pierre
Published: May 2021

Quand on parle de situation, il est important d’articuler trois concepts : situation, activité, apprentissage. D’une part, toute activité humaine se déploie en situation. D’autre part, on apprend des situations, quand celles-ci comportent un problème, qui requiert de l’apprenant une activité de conceptualisation. Le texte comporte deux parties : la première partie est une réflexion épistémologique ; elle propose un débat entre les tenants de la théorie de l’énaction et les tenants de la conceptualisation dans l’action, théorie à laquelle se rattache l’auteur. La deuxième partie, empirique, montre sur deux exemples comment les apprentissages professionnels combinent conceptualisation et recours à l’expérience.
« Des choses merveilleuses pour ce pays ». Narcos ou la difficile quête du perfectionnisme dans l’action politique
Authors: Collombon Maya , Mathieu Lilian
Published: May 2021

« Des choses merveilleuses pour ce pays », en l’occurrence la Colombie, c’est ce qu’ambitionne de faire le trafiquant de cocaïne Pablo Escobar alors qu’il cherche à entrer en politique pour y porter la parole des plus pauvres, dont il est issu. Cette ambition se heurtera à l’hostilité de l’oligarchie devant celui qui se pose en « Robin des bois » et qui y répondra par un déchaînement de violence. Elle se heurtera surtout à l’action de ceux pour qui une « meilleure Colombie » passe par l’éradication du narcotrafic et la restauration de l’autorité de l’État. C’est aux dilemmes moraux des protagonistes de Narcos quant à la légitimité des moyens à mettre en œuvre pour y parvenir que s’intéresse principalement cet article. La tentation, exprimée par les agents étasuniens de la DEA comme par certains secteurs de l’État colombien, de combattre le chef du cartel de Medellín par des moyens tout aussi illégitimes, et violents, que les siens s’oppose au respect absolu de la légalité (y compris lorsqu’elle sert les intérêts d’Escobar) incarné par le procureur général de Greiff. Cette tension est mise en scène dans la série au travers des hésitations du président Gaviria, dont les conversations avec son vice-ministre de la Justice appellent une réflexion en termes de perfectionnisme, en exprimant ses doutes quant aux moyens et aux fins du bon gouvernement (une paix octroyée au prix de concessions à Escobar, ou l’élimination du narcotrafiquant s’appuyant sur des paramilitaires et au prix d’une perte de souveraineté) et en exposant les limites du courage politique.

Authors: Palacios-Hidalgo Francisco Javier , Huertas-Abril Cristina A.
Published: May 2021

Due to the COVID-19 pandemic, it is necessary to explore new practices in language teacher education. English for Social Purposes and Cooperation, a socially-responsive and technology-friendly approach to English language learning, may help students around the world continue learning from home. This chapter analyzes the perceptions of a group of pre-service teachers after designing socially responsive materials specially created for the COVID-19 crisis. Action research is employed to improve teacher educators' activity and pre-service teachers' training, and a mixed-method approach based on grounded theory and content analysis is performed. Findings show that the experience has provided participants with meaningful examples of material design. This encourages teacher educators to include the proposed approach in their teaching and reveals the need for specific training in material design. Results may help prove the potential of action research for improving the teaching practice.

Authors: Trigos-Carrillo Lina , Fonseca Laura
Published: May 2021

Conducting critical community research during the COVID-19 pandemic has brought unexpected challenges to academic communities. In this chapter, the authors analyze the obstacles faced in a Critical Participatory Action Research (CPAR) education project with a rural community of former guerrilla members in the Amazon piedmont in Colombia. After this analysis, the authors present four CPAR principles to support critical community work during difficult times. The authors argue that communicative action, horizontal community participation in all the stages of the research process, time commitment, and the leverage of other competing needs should be guaranteed and maintained during times of crisis. CPAR offers opportunities to advocate better conditions for the most affected communities in moments of increasing inequality.
An Action Research Study on Globally Competent Teaching in Online Spaces
Authors: Kerkhoff Shea N. , Mardi Fatemeh , Rong Han
Published: May 2021

Research shows that teachers understand why global competence is important but do not necessarily know how to implement global teaching. One way to address this problem of practice is integrating global competence with teacher education. Education abroad is an effective method to internationalize teaching, but travel is suspended due to the global pandemic. At the same time, the pandemic also highlights how global cooperation and global competence are vital in mitigating the effects of the virus. The purpose of this action research study was to investigate the impact of infusing global learning in an online education methods course. Data sources included products of learning and reflections from 24 master's students. Findings include five themes (multilingual communication, current event awareness, content-aligned integration, utilizing students' identities, and practicing local-global inquiry) that describe the prerequisites, barriers, challenges, and successes as teachers develop global competence and implement globally competent teaching in their K-12 classrooms.

Published: May 2021

This study applied an adoption model, inspired by the Technology Acceptance Model (TAM) and Multipurpose Information Appliances Adoption Model (MIAAM), to compare key variables explaining adoption patterns of a mobile coaching app that guides and encourages students via a technology-based platform. This article constitutes a pioneer effort to compare adoption behaviors across a developed country and an emerging country (France and Mexico) with differences in level of use of mobile apps. A multi-group structural equation modelling approach was used to test the causal structure of the conceptual model. Results confirmed significant differences and similarities across samples and identified critical factors. Perceived usefulness was found to be the most important driver with mediating effects. Organizations implementing coaching services with an improved perceived usefulness could boost their adoption rates.

This paper presents an alternative utilisation of sago barks from the sago industry. In this study, a sago bark-derived magnetic adsorbent was developed by impregnation with ferric chloride hexahydrate (FeCl3H2O) and carbonisation method. The potential of the sago bark-derived magnetic adsorbent to remove lead ion (Pb2+) and copper ion (Cu2+) from aqueous solution was assessed in a batch system. Adsorption experiments were performed as a function of initial concentration (5.0 – 15.0 mg/L). The magnetic adsorbent displayed good ferromagnetic property which aids the separation of the adsorbent after the decontamination process. The magnetic adsorbent was characterised by Fourier Transform Infrared (FTIR) Spectroscopy and Scanning Electron Microscopy embedded with an Energy Dispersive X-ray Spectrometer (SEM-EDX). The FT-IR spectra analysis revealed the surface functional groups of the magnetic adsorbent are C−O−C, C−OH, C− H, −C−C−O, Fe-O, O-H, and C-O. The maximum monolayer adsorption capacities were discovered to be 172.414 and 12500 mg/g for lead and copper ions, respectively. The batch adsorption isotherms were analysed using Langmuir, Freundlich, Jovanovic and Temkin isotherm models. The experimental data perfectly fitted with Langmuir isotherm modelling. The results indicated that the sago bark-derived magnetic adsorbent potentially to be an alternative in replacing more high-priced adsorbents for its application in heavy metal ions removal.

Published: May 2021

Mismanagement of plastic waste has caused plastic leaking into nature and entering our food chain as microplastics, which may have negative impacts on wildlife and our health. However, data on microplastics in bottled water are still limited, especially in Sarawak, Malaysia. This study aims at investigating the presence of microplastics in the bottled water that manufactured locally. So that the F&B manufacturers and other key stakeholders can take necessary actions to prevent or minimize microplastics pollution in our drinking water. A total of 40 bottled MW and DW samples from 4 local products in Sarawak and Malaysia was investigated. A filtration and observation processes using the membrane filters (0.45 μm pore size) and digital microscope (Nikon Eclipse LV150N) were developed to identify and quantify the presence of microplastics based on their types, shapes, and sizes as criteria. A library database was also developed to ensure the consistency of this identification process. A total of 2022 microplastics with an average of 50.6 particles per bottle (500-mL packing) was detected in the samples. Bead, fibre, fragment and film were detected in all the samples, but fibre (48%) and fragment (36%) made up the majority (84%) of microplastics in the samples. However, microplastics in the MW samples were found 13% higher than the DW samples. This was also true across the products investigated in this study except between X (MW) and Z (DW). On the other hand, the results also indicated that the majority (66.7%) of microplastics smaller than 20 μm were consistently detected in all the samples. Nevertheless, other detection methods such as Raman, Fourier Transform Infrared (FTIR) Spectroscopy, etc. should be considered for a more thorough investigation. Lastly, it is important to revisit the sampling and testing procedures for similar studies like this to prevent or minimize any cross-contamination to the samples.
A Parametric Study of Coupled Photo-Electro-Thermal Responses of Thin Film a-Si:H Solar Cell with Embedded Nanoparticles

Published: May 2021

A parametric investigation has been performed on a thin-film hydrogenated amorphous silicon (a-Si:H) solar cell that is enhanced with various light trapping schemes through a modelling approach. The proposed model contains a novel coupling approach and various feedback routines for a more holistic modelling treatment. The proposed optical model adopts a semi-coherent method, the electrical model extends the classical drift-diffusion model to incorporate the effects of thermal gradients, and the thermal model adopts energy conservation equations from the hydrodynamic model. Based on the simulation results, it is observed that the rise in cell temperature adversely affects the electrical performance but promotes more optical absorptions due to the unique optical properties of amorphous silicon. To obtain an optimum enhancement from the inclusion of nanoparticles, their dimensions and separation distances are essential factors. The thickness of the intrinsic active absorbing layer affects the optical performance directly which then leads to various variations in electrical and thermal responses.
