RECOVERY AND UTILISATION OF MUNICIPAL SOLID WASTE INCINERATION BOTTOM ASH: IMPLICATIONS FOR EUROPEAN WASTE MANAGEMENT STRATEGY
Authors: Fletcher Carly Adele , Dunk Rachel
Published: June 2023

Over the last two decades, the stated intent of European waste management strategy has evolved from a specific focus on landfill diversion to enabling the transition to a circular economy.. Widespread introduction of source-segregation alongside deployment of material recovery technologies have improved MSW management practices across Europe. However, with diminishing returns it has become more difficult to achieve further landfill diversion through increased recycling alone, and incineration rates (across the EU-27 as a whole) have continued to increase. The advantages of incineration include the ability to harness the energy content of the waste alongside a sizeable reduction in mass and volume. However, the remaining solid residues, the most substantial being incinerator bottom ash, present a management issue. Exploring the role of incineration and the utilisation of incineration bottom ash, this paper highlights the potential risks of lock-in in the context of evolving waste policy. A simple thought experiment suggests that while increased use of incineration may help member states achieve 2035 landfill diversion targets, it would also carry a substantive risk of placing the 2035 recycling target out of reach. To address this, a long-term vision concerning the future of incineration is required, where it is recommended that policy which focuses on landfill diversion and the recycling of residual wastes should be strengthened through mechanisms that gradually phase out incineration and distinguish between open and closed-loop recycling.
Hazardous properties of mineral and organo-mineral plastic additives and management of hazardous plastics
Authors: Hennebert Pierre
Published: June 2023

Many plastic additives are mineral or organo-mineral substances having functions as pigments, heat stabilizers, flame retardants, process adjuvants and the like. Are additivated plastics hazardous when they become waste? Data from the Plastic Additives Initiative, a joint industry and EU effort, was used, along with substance hazard statements from the ECHA website and hazard properties from the waste classification. 20 elements of 91 substances, namely Al, B, Ba, Bi, Cd, Co, Cr, Cu, F, I, Li, Mn, Ni, Pb, Pr, Sb, Sn, Ti, V and Zn were selected, and their additives used in 11 polymers, considered. Of the 91 substances selected, 57 are non-hazardous or are hazardous but used at too low concentration to render the plastic hazardous when it becomes waste. 34 substances (= 37% of 91) are hazardous and make plastics hazardous as waste. These are mainly heat stabilizers (for PVC), or pigments and flame retardants (for all polymers). The sorting of these plastics by the mineral concentration of their additives with online XRF is theoretically achievable. With data from previous papers, 63 additives (= 27% of 233) make plastic hazardous. The brominated flame retardants are the less documented. Only essential use should be encouraged for pigments. Waste management today should focus on turning waste into non-waste, not waste leakage. With occupational safety and health regulations during processing, and with product regulations during its second life, the material should be managed as another hazardous or non-hazardous (virgin) raw material, and given end-of-waste status when it enters the loop.

Authors: Bello Hadi , Ajao Jamiu Olamilekan , Sadiku Nusirat Aderinsola
Published: June 2023

Sawdust and food waste have been part of solid organic waste causing great environmental pollution. Composting is a popular utilization method of converting waste like sawdust and food waste to sanitized and stabilized soil amendment. Unfortunately, many composting systems failed due to a dearth of information as a result of little or no scientific research focused on the effects of the physical properties of composting materials on the composting process. To fill this knowledge gap, three composting experiments of food wastes mixed with sawdust at ratio 20:80, 30:70, and 40:60 and compacted to different initial bulk densities of 15, 20, and 25 kg/m3 respectively was carried out to explore the effect of physical properties on composting of sawdust with food wastes. Physicochemical parameters monitored include bulk density; porosity; particle density, temperature, moisture content; pH, and electrical conductivity (EC). The highest temperature (65.3 oC) was recorded by trial 3 while trial 1 recorded the lowest temperature (49.3 0C). Among trials 1, 2, and 3, the maximum pH (9.2) and EC (5.1 mS/cm) were observed in compost trial 3. Additionally, the lowest pH (5.3) and EC (1.4 mS/cm) was observed in trial 1. Trial 3 had the highest percentage finest and lowest fibrosity content. A significant increase in bulk density, porosity, and particle density was observed in the three compost trials. The compost’s bulk density of (25 kg/m3) in trial 3 was observed to attain maturity and stability as compared with trials 1 and 2.
Analysis of secondary waste from a plastics recycling plant for the production of carboxylic acids
Authors: Vogt Kyra Atessa , Wenzel Leonie , Steinberg Iris
Published: June 2023

The production of bio-based platform chemicals through the chain elongation of short-chain carboxylic acids to medium-chain carboxylic acids by ethanol-acetat fermentation can be a contribution to the circular economy. To avoid further waste, secondary waste that already contains short-chain carboxylic acids can be used. The potential for the production of bio-based carboxylic acids from a secondary waste of a recycling plant for plastic waste is examined in this paper. Therefore, practical experiments with the process water of a recycling plant for plastic waste were conducted in order to assess the potential for carboxylic acids production. At the end of the experiment, the concentrations achieved by chain elongation in the secondary waste result in 496 mg/L butyric acid and 87 mg/L caproic acid and the concentration in the extraction solvent is 933 mg/L caproic acid. To conclude, chain elongation of carboxylic acids in secondary waste, in this case the process water from a treatment plant for plastic waste, is generally possible. In order to estimate the total potential for the production, the fluctuations of the quality of the process water have to be considered.
Influence of “El Niño Southern Oscillation” periods on plant density of Hoffmannseggia aphylla (Fabaceae) an endangered species
Authors: Carevic Felipe , Contreras Roberto
Published: June 2023

Backgrounds and aims: Studies on the natural regeneration of plant species under hyperaridity conditions have been scarce, mainly because of the low germination percentage of the species under these conditions. Presumably, sporadic phenomena such as the El Niño Southern Oscillation (ENSO) could have a positive effect on the natural germination of these species, although this effect has not yet been satisfactorily explored.
M&M: To test the crucial assumption of our statement, a hyperarid region (average rainfall below 5 mm/year) was used as a model to determine the effect of ENSO years on the natural regeneration rate of adult individuals of the endemic legume Hoffmannseggia aphylla (retama) in the Atacama Desert, northern Chile. Thus, the vegetation density of an endemic leguminous species in a sector of the Pampa del Tamarugal, Tarapacá Region, northern Chile, was analyzed for six years.
Results: The density of this species increased during ENSO years, mainly due to water flows from the highest sectors of the Tamarugal pampas, such as the town of Pica, in addition to the increase in humidity and summer rainfall.
Conclusion: Our results highlight the transcendence of the ENSO in the regeneration of leguminous plants.

Statistical Evaluation of Seismic Velocity Models of Permafrost
Authors: Ji Xiaohang , Xiao Ming , Martin Eileen , Zhu Tieyuan
Published: June 2023

The warming climate in high-latitude permafrost regions is leading to permafrost degradation. Estimating seismic velocity in permafrost can help predict the geomechanical properties of permafrost and provide information for planning and designing resilient civil infrastructure in cold regions. Seismic velocities of permafrost are mainly influenced by three components in permafrost: soil grains, water, and ice. Unfrozen water content reflects the variation of ice content and therefore is a key parameter in predicting seismic velocity. This paper statistically evaluates the performance of seven seismic velocity models in predicting seismic wave velocity of permafrost; these models are the time-average model, Zimmerman and King model, Minshull et al. model, weighted equation model, three-phase model, the Biot‐Gassmann theory modified by Lee (BGTL model), and Dou et al. model. The unfrozen water content used in these models is obtained from a modified Dall’Amico’s model that we propose and this new model is evaluated against six existing unfrozen water content models based on soil temperature. The data used in the evaluation are from published laboratory and in-situ data, including 369 data points for joint P- and S-wave velocities from 9 publications and 980 unfrozen water content data points from 13 publications. This study finds that permafrost of all soil types generally shares the same linear trends between P- and S-wave velocities, regardless of porosity, grain size, and temperature. Fitting all existing data, we derive an empirical linear relationship between P- and S-wave velocities. Among the seismic velocity models evaluated in this study, the Minshull et al. model and BGTL model are the most accurate in predicting seismic velocity of permafrost. The study also provides the applications of seismic velocity models for various permafrost soil types.
Effects of past and future autobiographical thinking on the working self-concept
Authors: D'Argembeau Arnaud , Garcia Jimenez Claudia
Published: June 2023

While the role of autobiographical memory in self-representation is well established, the identity function of future thinking has received much less attention. Yet, most people commonly imagine future events that convey meaningful information about the person they wish or expect to become. In three experiments, we assessed the extent to which thinking about such self-defining future events influences the current content of self-representation (i.e., the working self-concept). Participants were asked to think about either a past or future self-defining event, or a control topic, before describing aspects of their identity in the form of ‘I am’ statements (Experiments 1 and 3) or completing scales assessing self-related dimensions (Experiments 2 and 3). We found that thinking about a future self-defining event led participants to conceptualize themselves more in terms of their psychological traits, as did thinking about a past self-defining event. Furthermore, thinking about a future self-defining event increased the sense of present-future self-continuity, whereas thinking about a past self-defining event increased the sense of past-present self-continuity. These results suggest that self-representations are fuelled not only by autobiographical memories, but also by projections into the future.
Family Origins of Life Cycle Attainment: How Brother Correlations Overlap Over the Life Course
Authors: Karlson Kristian Bernt
Published: June 2023

Although stratification scholars increasingly study the role of family background in shaping attainment across the entire life course, research has yet to establish whether the family characteristics that shape attainment early in the career are the same family characteristics that shape attainment late in the career. Applying an extended sibling correlation approach to brothers’ life cycle earnings and family income in the U.S. National Longitudinal Survey of Youth 1979, I document a near-perfect correlation in the family characteristics that affect attainment at early, mid, and late career stages. This result carries important theoretical implications for how stratification scholars conceptualize the impact of family background across the career. Family background appears to constitute a single dimension in determining attainment across the life course. Further analyses also suggest that the imperfect relationship between current and lifetime income is driven exclusively by within-family processes.

In this study, the molecular structure, vibrational frequencies, and atom-in-molecule (AIM) analysis of the benzoic acid monomer and dimer were investigated. Geometry optimization and vibrational frequency calculations for the monomer and dimer were carried out at the density functional theory (DFT) level with the 6-311++G(2d,p) basis set. UV-Vis spectroscopy and electronic properties (i.e., excitation energies, oscillator strengths) were calculated by time-dependent DFT (TD-DFT) in different solvents. The calculated absorption values mainly represented excitation from HOMO-1 (H-1)  LUMO and HOMO  LUMO+2 (L+2). The structure-activity relationship was interpreted by its molecular electrostatic potential (MEP) surface, which is very useful to the research of molecular structures and their physiochemical-property relationships. The highest occupied molecular orbital (HOMO)-lowest unoccupied molecular orbital (LUMO) energy was analysed. The HOMO-LUMO energy gap and other related molecular properties were also calculated. In addition, natural bond orbital (NBO) analysis was carried out to investigate the various intra-intermolecular interactions in the molecular system.

To comprehensively manage wound infection, tri-layer fibre membranes have been designed with two antibacterial agents, including silver nanoparticles (AgNPs) and chitosan oligosaccharide (COS), and their antibacterial properties were evaluated using qualitative and quantitative tests. While the first polycaprolactone (PCL) silver layer and the second plasma-treated PCL layer were fabricated by electrospinning, the third COS layer was constructed via coating and heat-vacuum drying. The formation of the membranes and their fibrous and porous structures were examined using scanning electron microscopy (SEM). The antibacterial activities of the membranes against Pseudomonas aeruginosa, Escherichia coli, and Staphylococcus aureus were examined by disk diffusion and percentage reduction assays, which were performed simultaneously as per the certificates from the Ministry of Health Institute of Public Health in Ho Chi Minh city. The tri-layer membranes, named PCLAg50/PT (plasma treatment)/COS and PCLAg500/PT/COS, achieved desirable antibacterial results with extensive inhibition zones and bacterial reduction rates ranging from 99-100%. In addition, while the PCLAg500 membrane exhibited broad inhibition zones and reduction rates ranging from 94.6-97%, the PCLAg50 membrane achieved reduction rates ranging from 67.5-82.1% despite the absence of inhibition zones. As a result, the fabricated tri-layer membranes could reduce local and opportunistic infections. Depending on infectious risks, the concentration of silver utilsed as an infection-prevention agent must be adjusted from 50 to 500 ppm to ensure safety.

Authors: Telebuh Mirjana , Bertić Želimir , Grozdek Čovčić Gordana
Published: June 2023

Functionality in activities of daily living and social support are often used as indicators of quality of life, especially in research involving gerontological and geriatric populations that assesses the functional independence of the patient and their need to rely on help from others.The effects of a stroke can significantly reduce the quality of life of the elderly. Therefore, the aim of this paper was to examine the relationship between functionality and social support and the quality of life of elderly stroke patients. This study included 50 stroke patients over the age of 65 years. All the participants lived at home in Zagreb. The participants’ quality of life was measured using The World Health Organization Quality of Life Brief Version (WHOQOL-BREF questionnaire), which determines quality of life based on four domains (Physical, Psychological, Social relationships, and Environment). Functionality was measured using the Functional Independence Measure, while social support was measured using the Social Support Scale. The correlation between functionality and quality of life was statistically significant with respect to physical health (r = 0.77, p < 0.00), as well as psychological health (r = 0.53, p < 0.00). The correlation between social support and quality of life was also significant with respect to social support from friends in the Social relationships domain (r = 0.40, p < 0.00) and in the Environment domain (r = 0.45, p < 0.00), as well as in the overall social support in Social relationships (r = 0.29, p < 0.04) and Environment domains (r = 0.35, p < 0.01). A higher level of functionality indicates a higher quality of life in the Physical and Psychological domains, as well as in the overall quality of life of elderly stroke patients. Strong social support from friends can encourage and help elderly stroke patients to integrate into their social environment more successfully, thus potentially increasing their quality of life. The results of this study imply that functionality and social support can be important factors in the quality of life in elderly stroke patients.

Framing a Model for Mobile Learning Using Augmented Reality
Authors: Radosavljević Slavica , Radosavljević Vitomir
Published: June 2023

This paper considers the possibility of creating a framework for mobile learning with elements of augmented reality, intending to better adapt teaching content to students who are in the same or different loca­tions. The framework, in which the use of mobile devices in learning is ob­served, depends on the purpose for which the mobile device is used (for re­search purposes, simulation, etc.), on technical capabilities, and the level of user capabilities. The goal is to achieve a quick and efficient understanding of the learning content, as well as good cooperation from the participants. The sustainable link between AR and HE goals must be established in ac­cordance with the cognitive approach, according to the axioms of the theo­ries related to learning, with the aim of unifying the association of this tech­nology with the teaching–learning process.
A Proposed Blockchain-Based Solution for a Data-Driven Vehicle Lifecycle Management
Authors: Barolli Ezmolda , Zeneli Muhamet
Published: June 2023

Vehicle lifecycle data and stakeholders’ data related to it have a non-open approach to data access. The lack of accurate, reliable, trans­parent, and accessible data consequently leads to a lack of trust, but also a risk analysis that is not always relevant. This paper consists of analyzing the factors to determine if a blockchain-based solution could increase trust and collaboration between different stakeholders in vehicle lifecycle man­agement and the insurance industry. The goal is to model a data-driven ap­proach on a blockchain-based solution that helps reduce barriers to finding data on all vehicle transactions. The methods used are based on the anal­ysis of the current systems and platforms of vehicle lifecycle management and insurance policies from the business model perspective and security as­pects. The proposed technical solution consists of a general architecture for a permissioned blockchain-based vehicle lifecycle management used by manufacturers, insurance companies, and other stakeholders.

Halotrichite has been identified in geothermal fields of the Kambalny-Pauzhetka-Koshelev region, the Bolshoi Semiachik complex, and the Mutnovsky volcano (Kamchatka, Russia). Halotrichite forms efflorescence on soils heated up to 70°C, around steam-gas vents and boiling springs. Tschermigite, rozenite, szomolnokite, gypsum, alunogen, barite, melanterite, hexahydrite, and minerals of the copiapite, alunite and voltaite groups were found in close association with halotrichite. The chemical composition of halotrichite samples from different geothermal fields is similar and characterized by Mg substitution in the Fe2+ position, with Fe2+:Mg ratio ranging from 90:10 to 50:50, and also by Fe3+ substitution in the Al position in some samples, with Al:Fe3+ reaching up to 85:15. Halotrichite is a typical mineral of low-temperature volcanic setting, formed as a result of alteration of parent minerals by hydrothermal fluid and represents an intermediate form of crystallization of leached elements. At the same time, the local conditions of mineral formation — such as variations in Eh, pH, surface temperature, and elemental composition — do not reflect in the chemical composition or other thin typomorphic features of halotrichite. The mechanism of halotrichite formation is probably identical in both geothermal fields and zones of oxidation of sulfide deposits.

A Ciência é um caminho construído por homens e mulheres, porém a presença das mulheres na História da Ciência é uma questão que sinaliza atenção e necessita de uma transformação no que diz respeito a imagem de quem faz Ciência. O machismo cientifico criou barreiras e silenciou mulheres que foram essenciais para o conhecimento cientifico. Esta pesquisa buscou explorar o Google como recurso tecnológico, considerando a ferramenta como base de dados.  A pesquisa realizada teve como objetivo analisar como são apresentados os principais resultados da plataforma Google em três línguas: Português; Espanhol e Inglês, utilizando os termos meninas ciência; chicas ciências e science girls. As pesquisas indicam que a partir de 2009 as questões de gênero na Ciência vêm recebendo maior atenção. Além disso, constatou-se que os resultados em Português em sua grande maioria fazem referência a projetos de extensão de Universidades Públicas do Brasil. Dois projetos de extensão de Universidades Federais podem ter inspirado na criação de outros projetos sobre a temática no Brasil. O público alvo desses projetos são meninas do Ensino Fundamental. No ensino fundamental o Ensino de Ciências pode servir como um espaço fundamental para aproximar meninas de discussões sobre a participação das Mulheres na Ciência.

The recent outburst of COVID-19 has utterly revolutionized the world in every sector of life, be it health, economy, tourism, employment or education. Internet revolution, for the first time, with such pace and potential played the most important role amidst crises. Though, work from home and virtual education system have been existing long before the outburst of COVID-19, however, the rampant and widespread use of internet appeared as a result of global pandemic which mandated social isolation as the most important COVID combating measure. It was the December of 2019, when COVID-19 outburst in the Chinese district of Wuhan and then started spreading to other countries. Along with many other measures to combat the situation, virtual education system was introduced at every level of education; PG, primary, secondary, higher secondary, graduation and post-graduation level. Once, the global expedition for vaccination is launched successfully, and many people got vaccinated as well, and the danger of COVID-19 shattered to an extent, different institutions started to normalize their systems to the pre-COVID-19 era. Readjustment to the traditional education system from virtual/ online education system was also commenced. When the online or virtual education system was launched, it wasn’t adapted without hardships, like learning to use virtual education tools to the problem of the affordability of these tools and access to internet. However, once the whole education system switched to the virtual class system, a call back to the traditional education system came, since the hovering threat of COVID spread was shedding away. To this, the reaction was observed. Many of the students wanted to continue their education with the online/virtual system, for which, they present many reasons. This research paper targets the population of the university students and aims at exploring the difficulties the university students are facing in readjustment to the traditional education system. Also, some recommendations are given to ease the issue of readjustment to the traditional education system keeping in view the targets of educational institutes.

This community service aims to help improve the community's food security by utilizing narrow land with hydroponic techniques. The land in the Pakal District, Surabaya City, is included in the narrow land caused by land use change. In addition, this community service provides real knowledge and skills on hydroponic planting procedures. The methods used are observation, discussion, simulation, and project-based mentoring. These simulations and mentoring activities consist of several activities, namely land cleaning, garden making, seedling cultivation, plant maintenance, and hydroponic plant harvesting. The results of the activities show that the program can be well implemented, as seen from the enthusiasm of the community to participate in opening the land and planting hydroponic plants from start to finish. The hydroponic land initially was neglected and poorly maintained. After this program, the previously neglected land was transformed into a beautiful garden, and the hydroponic land can be utilized by the surrounding community to grow vegetables or plants needed for daily life.

Primary teacher working group assistance is one of the preparations for the teacher working group (KKG) in preparing the existing work program. The purpose of carrying out this activity is to carry out assistance to the SD teacher working group in designing an annual work program. The mentoring method used is the GROW Coaching Model approach which consists of 4 main stages, namely Grow, Reality, Options, and Will. The subjects of this activity were elementary school teachers in the Indonesia-Malaysia border region, especially in the KKG Group I Saka Taru environment, Lumar District, Bengkayang Regency, West Kalimantan. Mentoring activities are carried out by first delivering discussion material related to relevant activities as an example of an annual work program that can be carried out by the KKG Group I Saka Taru. The next stage is to make an annual work program roadmap and indicators of achievement in the implementation of the annual work program. This SD teacher working group assistance has produced an annual work program that is ready to be implemented one year ahead

Big Data in healthcare: cybersecurity and legal protection of personal data
Authors: Polubinskaya Svetlana V.
Published: June 2023

Digitalization of Russian healthcare leads to an increase of digital medical data, which eventually becomes Big Data and requires secure ways to collect, process, store and use such information. In this article, the authors analyze legal acts that govern ways to protect medical information in digital form, as well as those that establish the legal regime of personal data. The authors draw attention to the risks of re-identification of anonymized medical data and difficulties to comply with some requirements of the personal data legislation in use of Big Data technologies. In discussion on liability for offences and crimes in the sphere of computer information, the authors propose to consider healthcare information systems containing personal data as objects of critical information infrastructure of the Russian Federation. Such regime would allow to charge unlawful access to the information contained and other criminal acts under Article 274¹ of the Criminal Code of the Russian Federation. Prevalence of information and communication technologies as a method of encroachments on the digital medical data, and ultimately an intrusion into privacy, leads authors to the conclusion about expediency of addition of Article 137 of the Criminal Code of the Russian Federation with the relevant aggravating circumstance.
