The manufacture of ceramic brick goes through the stages of raw material extraction, clay homogenization, material conformation, drying and firing. Drying is the phase that needs greater care, as it involves removing part of the moisture from the brick, in order to preserve its quality after process. This work aims to predict heat and mass transfer in the drying of ceramic bricks in oven using computational fluid dynamics. Considering the constant thermophysical properties, a transient three-dimensional mathematical model was used to predict mass and energy transfer between the material and air during the process. Drying simulations at temperature of 100°C were performed with the air flow in the frontal direction to the ceramic brick holes and the results were compared with those obtained for the air flow in the perpendicular direction to the brick holes reported in the literature. It was found that the position of the brick in relation to the direction of air flow inside the oven affected directly the drying and heating kinetics, and the distribution of temperature and moisture content inside the brick. The positioning of the holes in the brick parallel to the direction of the air flow resulted in reduction at the drying time and, consequently, in energy savings in the process, more uniform drying, and improvement in the product quality.

Published: August 2022

We study in this work, the occurrence of defects modes in the transmission spectrum and the band structure of a perfect photonic asymmetric serial loops structure (ASLS) utilized for narrow-band filtering. The perfect structure presents large photonic bandgaps that result from the modes of the loops resonances and the system periodicity. Besides that, the existence of defects within this perfect ASLS, whether at the segment or loop level, or both of them, causes the appearance of two, three, or four defect modes within gaps with good transmission rates and high-quality factors. These defects modes are extremely sensitive to changes in structural parameters. This system can be used to filter or guide the incoming electromagnetic waves. The interface response theory has been used to accomplish the analytical calculation. Green's function of the full system is determinated using this method. It allows us to calculate the dispersion relation and the transmission rate. Therefore, this paper can provide ideas for the design of multi-channel tunable filter using for frequency division multiplexing and microwave and signal processing.

The growing concern with the environment has driven the development of new technologies for the treatment of produced water. In this context, the filtering hydrocyclone appears as an interesting alternative for the treatment of these waters contaminated with oil from the petroleum industry. This research addresses the flow of fluids inside a hydrocyclone equipped with a porous wall (membrane) containing two tangential inlets and two concentric outlets, with the aim of study the impact of the formation of the polarization layer by concentration on the oily water separation process using CFD. Concentration fields and transmembrane pressure, concentration, and permeate flux profiles are presented and analyzed. The results show that the proposed filtering cyclonic separator concentrates the oil in the central region of the equipment, however, for high oil concentrations; the core expands and approaches the porous wall. Furthermore, the increase in the oil volume fraction causes a decline in the permeate flux, and an increase in feed velocity causes a decrease in the polarization layer.

Published: August 2022

Barkcloth a naturally occurring cellulosic non-woven fabric has recently obtained attention within the scientific community for end use applications in various industries for instance automobile, household furnishing and construction owing to its robust mechanical, thermal and sound absorption properties. In this work, barkcloth was treated with different concentrations of zinc oxide nanoparticles which were deposited with the pad-dry-cure procedure. The Gram-negative Escherichia coli (E. coli) and Gram-positive Staphylococcus aureus (S. aureus) were chosen for the evaluation of the anti-microbial efficacy of Zinc oxide Nanoparticles (ZNPs). The coated barkcloth samples with ZNPs concentration 0.6 g/L optimally performed against the two most common resistant bacteria i.e. the gram +ve and gram –ve bacteria, with the gram negative E-coli bacteria demonstrating a high susceptibility to the ZNPs than gram positive S-aureus.

Authors: Zhang Jin Yang , Zhang Xiao , Chen Jian Yu , Chen Xian Shuai
Published: August 2022

The effect of angle abutment on the stress distribution of bone tissue around implant is not clear. Using abutments with different gingival height (GH) may cause changes in the stress distribution of the implant and implant-bone interface. This study aims to investigate whether angled abutments with varied GH have a significant effect on stress distribution of surrounding bone and the biomechanical behavior of the implant system. Three implant-supported restoration models were designed by changing the angled abutment GH (1 mm, 3 mm and 5 mm). Force of 200N was applied on the crown surface at 45° to the long axis of the implants. The biomechanical performance of the restorations (including implants and angled abutments) and stress distribution pattern were evaluated by finite element analysis (FEA). Results showed that angled abutments with larger GH resulted in increased stresses on the implant and implant-bone interface.
A Brief Study on Defect Reduction of Cast Fe-Ni-Cr Alloy (UNS N08120) for Petrochemical Industry
Authors: Samvatsar Kaustubh , Dave Harsh
Published: August 2022

In the current advancing world, operability and ease in processability of a material define its selection criteria for the intended applications. Hence, the industrial applications requiring high temperature sustenance, strength and corrosion resistance desperately demand the materials which employ simple processing in an economical way. Contemplating last few decades, it has been discovered that industries like petrochemical, power generation, nuclear energy, etc. greatly relied on nickel-based alloys till Fe-Ni-Cr based alloys were not introduced. The usable components are obtained either in cast or wrought form as per requirements. Fully killed alloy, developed under controlled conditions with some precautions during the casting process can lead to sound casting. The current study adopts a novel preliminary approach to control the quality of cast UNS N08120 material and minimize the possibility of defect generation. The possible reasons behind cast defects and how they transform into intrinsic defects have also been discussed. Calcium-based fluxes are introduced to molten metal as a degassing agent for the elimination of lighter impurities and entrapped gases. By the addition of quicklime (CaO) as a flux material during the sand casting process, an attempt has been made to reduce the presence of gases and impurities by more than 80%.

Published: August 2022

We have recently demonstrated that basophils are protective against intestinal permeability during malaria and contribute to reduced parasite transmission to mosquitoes. Given that IL-18 is an early cytokine/alarmin in malaria and has been shown to activate basophils, we sought to determine the role of the basophil IL-18R in this protective phenotype. To address this, we infected control [IL18rflox/flox or basoIL-18R (+)] mice and mice with basophils lacking the IL-18R [IL18rflox/flox × Basoph8 or basoIL-18R (−)] with Plasmodium yoelii yoelii 17XNL, a nonlethal strain of mouse malaria. Postinfection (PI), intestinal permeability, ileal mastocytosis, bacteremia, and levels of ileal and plasma cytokines and chemokines were measured through 10 d PI. BasoIL-18R (−) mice exhibited greater intestinal permeability relative to basoIL-18R (+) mice, along with increased plasma levels of proinflammatory cytokines at a single time point PI, day 4 PI, a pattern not observed in basoIL-18R (+) mice. Surprisingly, mosquitoes fed on basoIL-18R (−) mice became infected less frequently than mosquitoes fed on basoIL-18R (+) mice, with no difference in gametocytemia, a pattern that was distinct from that observed previously with basophil-depleted mice. These findings suggest that early basophil-dependent protection of the intestinal barrier in malaria is mediated by IL-18, and that basophil IL-18R–dependent signaling differentially regulates the inflammatory response to infection and parasite transmission.

Authors: Schlabach Gretchen A. , Colston Marisa A. , Baker Carrie
Published: August 2022

Context

Professional values (PVs) of health care providers influence their professional decisions and behaviors. Athletic training is one of the remaining health professions without established shared PVs. Commitment to shared PVs, also known as core values, prompts good and right behavior by guiding moral and ethical judgment and professional decision-making.

Objective

To identify shared PVs in athletic training that enable the use of a values orientation, which facilitates adherence to legal, ethical, regulatory, and professional standards.

Design

Cross-sectional survey study.

Setting

Web-based surveys.

Patients or Other Participants

The Athletic Training Strategic Alliance leadership (n = 61/95), National Athletic Trainers’ Association (NATA) membership (n = 4837/35 279), and NATA committee members (n = 277/423).

Main Outcome Measure(s)

Our research consisted of 3 studies, each using a web-based survey to identify shared PVs, as well as a definition and sample behaviors for each PV.

Results

Using a 3-tiered systematic and inclusive process, we identified caring and compassion, integrity, respect, competence, and accountability as the shared PVs among athletic trainers. Definitions and 3 sample behaviors have also been provided and endorsed for each of the 5 shared PVs.

Conclusions

With the establishment of these shared PVs and their recent addition to the NATA Code of Ethics, athletic trainers can immediately incorporate a values orientation into their professional practices.
Incidence of Psychiatric Illness Among COVID-19-Positive Individuals with and Without Loss of Smell or Taste Symptoms in a Tertiary Care Hospital in South India – A Prospective Cohort Study
Authors: Shankar S. , Rahamathulla M. Mohamed Ilyas
Published: August 2022

Background:

COVID infection is known to cause acute and long-term neuropsychiatric presentations. Coronavirus infections are known to have neuroinvasive potential with consequent neuropsychiatric manifestations.

Materials and Methods

The study was conducted in a tertiary care hospital, and COVID-19-positive individuals were grouped based on the presence or absence of loss of smell (anosmia) or taste symptoms (ageusia). Group 1 without smell or taste disturbance, and Group 2 with smell or taste disturbance. Both groups were followed up for 6 months to assess the new onset of psychiatric illness.

Results

The onset of new psychiatric illness was present in 8 out of 30 (26.66%) cases in group 2 when compared with 2 out of 30 (6.66%) cases in Group 1, with a relative risk of 4 (95% confidence interval 0.9247–17.3023). In 10 cases, the pattern of psychiatric illness was depression (16.66%), anxiety (6.6%), posttraumatic stress disorder (3.33%), acute psychosis (3.33%), and acute stress disorder (3.33%). Both groups were compared in terms of socio-demographic profile, inflammatory markers, and computed tomography severity score, and no significant difference was noted between the two. A relative risk of 4 indicates that COVID-19-infected individuals who lose their sense of smell or taste are more likely to develop new-onset psychiatric illness.

Conclusion

Impact of COVID-19 on the central nervous system is very evident, and loss of smell or taste symptoms could be an early marker. Early recognition and prompt treatment with immunotherapy or newer therapies will prevent the emergence of psychiatric disturbance and its disability.

Indonesia's local rice varieties (Oryza sativa L.) have a wide range of diversity that can be valuable sources for crop improvement with molecular markers. This study investigated local rice varieties' genetic diversity and population structure using simple sequence repeat (SSR) markers. The SSR markers demonstrated their informativeness for genotypic characterization as represented by the gene diversity indices and polymorphic information content. The UPGMA dendrogram divided 63 varieties into two distinct clusters with different levels of sub-grouping and the tendency according to their origins, as supported by PCoA. In contrast, PCA of these varieties according to agro-morphological traits was scattered in all quadrants. Thus, DNA level variation analyzed by SSR seems to complement the phenotypic traits, which were not well structured and revealed significant genetic diversity among varieties, within, and among populations (P<0.01). The pattern of grouping structure analysis of total varieties into two subpopulations is similar to the dendrogram according to SSR markers but better resembles the pedigree information of the set local varieties. These findings have implied their importance in rice breeding for genetic improvement, maintenance, and management of local genetic resources in Indonesia.

Published: August 2022

Cardiovascular disease (CVD) is the leading cause of global mortality and disability. Hyperlipidemia is a major risk factor for CVD that can be controlled through medical therapy, appropriate nutrition, and lifestyle. This study aimed to identify the cang salak tea diet’s effect on the ApoC3 gene expression in a hyperlipidemia rat. 18 male Wistar rats were divided equally into three groups. A high-fat-diet-induced two groups of rats, and one group was the control. Once hyperlipidemia had been achieved, one of the two groups was treated with the cang salak tea, and one group was given a standard diet for four weeks. Authenticated rat and liver tissue were collected as a source of RNA isolation. Isolated RNA was used as a reaction template for the relative quantitation qPCR using β-actin as the housekeeping gene. The ApoC3 gene was specifically amplified with a Tm value of 82.73°C, Cq 17-19, and produced a sigmoid curve. The relative expression level of the ApoC3 gene in hyperlipidemia rats fed with the cang salak tea diet was 0.46 times significantly lower than the control (1.17) and P2 (1.32) groups. These results indicate that the cang salak tea has antihyperlipidemic properties to reduce CVD risk.

Bambara groundnut (Vigna subterranea (L.) Verdc.), also called ground peas or Bambara groundnut, is a West African seed legume of the Fabaceae family, playing an important social and economic role. The objective of the current study was to determine the occurrence, distribution and incidence of this disease on Bambara groundnut in agroecological production zones in Benin and to identify the causal agents responsible for the damages caused to the crop. A survey was conducted from 2019 to 2020 in five agroecological zones (AEZs) of Benin (AEZ2, AEZ3, AEZ4, AEZ5 and AEZ6). A total of 30 fields of Bambara groundnut were surveyed from 10 municipalities located in the agroeclogical zones of production at the early vegetative stage of the crop. Fields’ size of 0.5 ha were selected and scouted alongside both diagonals to evaluate the damping-off disease incidence. The results showed that damping-off occurred in four out of the five AEZs surveyed. The incidence rates varied from 0.00 to 23.33% in the AEZs 5 and 6 in 2019, and from 0.00 to 18.33% in the AEZ 6 in 2020. The highest incidence rates were obtained in the West Zone of Atacora (AEZ 4) and in the Food crop region of South (AEZ 3). Results of the correlation test showed a relationship between incidence, distribution of damping-off and climatic factors. However, most of regression equations showed a strong relationship between chemical properties of soils and incidence of damping-off. Sclerotium rolfssi was identified in the laboratory as the causal agent of the damping-off disease and isolated from diseased plants in the fields and during greenhouse pathogenicity tests. To the best of our knowledge, this is the first report of identification of pathogenic fungus as the causal agent of damping-off on Bambara groundnut seedlings in Benin.

The aim of becoming a society based on the rational utilization of the natural resources, has led to the consideration of many alternatives by academic and industrial sectors. The forest sector may be particularly prominent in trying to achieve these goals when using residues of their processes, for timber and pulp production. One of the most important requirements in society is the energy production. Co-products of wood processing and cellulose mills can be used for bioenergy generation. The densification of biomass involves handling, transportation and storage issues, and furthermore, when industrial forest residues such as lignin are added to this biomass, the final energetic product may have some improved properties, adding value to the chain. The purpose of this study was to evaluate the usage of the woody industrial waste, the sawdust from Joannesia princeps Vellozo enriched with Kraft lignin as an additive, aiming to produce briquettes. One of the main findings from this work was the possibility to obtain a briquette with better properties (higher bulk density and higher resistance) when using 6% of Kraft lignin as an additive and a pressure of 1500 PSI.

Este artigo tem como objetivo apresentar a análise de narrativas autobiográficas referentes a experiências de intercâmbios vividas por duas professoras-pesquisadoras no doutorado em uma universidade da Espanha no âmbito da aprendizagem e apropriação da língua espanhola e outros saberes. Neste sentido, o planejamento e a execução deste trabalho se deram, inicialmente, no diálogo das pesquisadoras sobre internacionalização, através de um minicurso, com estudantes vinculados à licenciatura em Letras - Língua Espanhola, e durante uma mesa-redonda em uma Semana Universitária, com alunos de diferentes cursos e instituições de ensino, além do público externo em geral, durante o ano de 2021. Para fomentar o registro desses diálogos e a realização deste estudo, utilizamos a metodologia de narrativas autobiográficas, de caráter informativo-descritivo, para coletar os relatos das experiências internacionais por meio dos diários de campo das duas professoras-pesquisadoras em questão, abordando as dimensões de ingresso e permanência na formação doutoral no exterior. Os resultados da pesquisa indicam, entre outros aspectos, que o financiamento da formação acadêmica no exterior é uma dimensão importante, pois interfere em diferentes sentidos, em particular, na escolha do destino, sobretudo para acadêmicos de baixa renda. Além disso, as narrativas de estudantes do Sul Global remetem a aprendizagens distintas durante o intercâmbio (língua estrangeira, currículo, história, geografia, cultura etc.), bem como constituem-se em ponto de referência para análises de políticas públicas e práticas de internacionalização.

Published: August 2022

Embora seja um processo que ocorre há muitos anos, a internacionalização do ensino superior intensificou-se nas últimas duas décadas devido ao avanço da globalização junto às tecnologias de comunicação. No cenário brasileiro, ela ganhou maior destaque na última década com a criação do Programa Ciências sem Fronteiras (CsF), o que contribuiu para que um número maior de instituições de ensino superior acelerasse suas agendas de internacionalização. Inserida neste contexto, a mobilidade é uma das principais atividades desse processo e promove uma interação cultural e cognitiva entre universidades e nações. Nos últimos anos, as universidades paranaenses destacaram-se em rankings sul-americanos e mundiais por adotarem práticas que visam à internacionalização das suas atividades. Inserido nesse contexto, este trabalho tem como objetivo investigar como a mobilidade é apresentada nos documentos oficiais das sete universidades estaduais paranaenses. Para atingirmos tal objetivo, guiamo-nos pelos estudos da internacionalização, como o de Knight (2004, 2012), De Wit (2015, 2019) e Finardi (2015); pela Terminologia de Krieger e Finatto (2020), Barros (2004), Barbosa (1998, 2004) e Faulstich (2001). A metodologia escolhida foi a Linguística de Corpus (BERBER-SARDINHA, 2004), utilizando-se o software Sketch Engine. O corpus de estudo é composto pelos documentos de política ou plano de internacionalização das instituições estaduais do Paraná. Após a análise, constatamos que o termo “mobilidade” ocorre como hiperônimo e seus hipônimos demonstram como ela é tratada nos documentos institucionais.

Published: August 2022

The following were the identified and defined classes of emerging contaminants of concern (ECCs): pharmaceutical and personal care products (PPCPs), perfluorinated compounds (PFCs), plasticizers, agrochemicals, industrial additives and agents (IAAs), flame retardants (FRs), Nanopar-ticles (NPs), steroids and hormones, gasoline additives. From 1983 to 1990, an estimated 15,000 metric tons of pesticides were reported to have been imported annually. In 2016, a yearly application of about 130,000 metric tons of pesticides was reported for Nigeria. Nigeria’s pesticides imports were worth USD128.671 in that year. Of the applied pesticides, about 85% ended in the environment as contaminants/pollutants. While few individuals in the households or neighbourhoods deal with pesticides, almost all human beings deal with PPCPs. PPCPs are taken to prevent or cure diseases and/or to sustain wellbeing. Nigeria produced 30 % of its PPCPs demands while 70% imported. In 2012, 2013 and 2014, Nigeria imported PPCPs worth USD425 million, USD481 million and USD530 million respectively. In 2018, Nigeria imported PPCPs worth USD606.31 million, while the total amount of pharmaceuticals procured was USD866.16 million. Almost all the candidates of ECCs had been detected in the Nigerian environment. Untoward episodes of pesticides abuse ranging from abuse to death, have been profiled. Some of the factors responsible for these were weak regulatory instruments on accessing these pesticides, bad economy, stigmatization and lack of resilience.

Manufacture and Design an Apparatus for Measuring the Thermal Resistance of Building Materials
Authors: Saliby Ammar , Kovács Béla
Published: August 2022

A good thermal design of buildings plays a key role in reducing the thermal loads of heating and air conditioning systems and thus reducing energy consumption. This study develops a steady-state apparatus for measuring the thermal resistance of building materials by using an absolute technique. The apparatus is designed to accommodate the full and actual size of the tested samples of building materials used in the Syrian market to ease testing. Therefore, suitable samples do not have to be built for the apparatus; the thermal resistance is measured for many samples, and the results are compared with the thermal insulation code for buildings in the Syrian Arab Republic. The results show that the difference between the resistance values obtained from the experiments and the Syrian thermal insulation code is due to the materials used in the local markets and their non-compliance with the code. These materials need testing and quality control during the manufacturing process.

THE EFFECT OF CORPUS-BASED ACTIVITIES ON VOCABULARY ACQUISITION OF A1-A2 LEVEL SEVENTH GRADERS - A CASE STUDY
Authors: Rizvić-Eminović Edina , Neslanović Vildana
Published: August 2022

Corpus-based activities (CBAs) have been used in FLT in recent decades, especially in countries where educational systems are well developed. However, this is not the case in Bosnia and Herzegovina. That is why a case study was conducted in a primary school in Bosnia and Herzegovina including 48 7th grade students divided into an experimental and a control group to investigate the effect of the use of corpus-based activities on vocabulary acquisition. In both groups blended learning methods were applied due to COVID restrictions. The aim was also to determine whether the use of CBAs had any impact on the students' motivation for participating in vocabulary learning activities. The students' results achieved in the pre- and post-tests which included new vocabulary items were analyzed and compared. The students' responses in the five-point Likert scale motivation questionnaires completed prior to and after the use of CBAs were also compared and discussed. Statistical analysis of the results confirmed that there was a positive effect of the use of CBAs on vocabulary acquisition of A1 – A2 level seventh graders, as well as on their motivation for participating in such activities. Contrary to statistically significant improvement in vocabulary acquisition, there is no statistically significant increase in the motivation to learn new vocabulary items in either of the groups, for which some possible explanations are also discussed in the paper.

Published: August 2022

This study investigated the growth mindset of college students in English language learning and the challenges they encounter in an online setting. Using a researcher-made questionnaire about the growth mindset of college students in English language learning and the challenges they encounter in an online setting, data from the 60 respondents in the study coming from the different colleges or departments of the Notre Dame of Midsayap College were analyzed quantitatively. Findings indicated that students have a high growth mindset and that factors such as motivation, criticism, environment, and effort had played a major role in their English language learning. Major challenges of students in an online setting include finding difficulty in accessing online materials due to poor internet connection, experiencing headaches and body pains due to prolonged exposure to gadgets, and getting bored easily when class time is too lengthy. The least challenges encountered by students in an online setting yet also hampered their learning are lacking gadgets such as a cellphone and laptops, feeling disconnected from the instructor, and excessive workloads. Furthermore, there is no significant difference in a growth mindset in terms of sex and college or department. However, it was found out that College of Nursing (CN) got the highest mean when it comes to their growth mindset. Meanwhile, College of Information Technology, and Engineering (CITE) got the lowest mean. Moreover, there is a significant relationship between the growth mindset of English language learning and the challenges they encountered in an online setting.

Authors: Cudillo Christine Joy A. , Mutya Romel C. , Adlaon Mauricio S.
Published: August 2022

This study investigates parents' challenges and their child's academic performance in science in modular distance learning. It also tests the significant difference between parents’ challenges to their profile variables and their child’s academic performance. In this descriptive-survey research design, data were gathered from 318 parents of secondary students in public secondary schools situated on the island using convenience sampling. Gathered data were systematically treated and analyzed using frequency, percentage count, mean, standard deviation, one-way analysis of variance (ANOVA), and Pearson-r correlation. Findings revealed that individual-related challenges such as finances, supervision of child's studies, and poor teaching skills were the most significant challenges parents experienced in implementing modular learning. Parents disagreed that instructional and institutional challenges affect them in modular distance learning. The respondents' children performed satisfactorily in science during the first and second quarters of the school year. There was a moderately significant relationship between individual-related and instructional-related challenges. However, a weak significant relationship is surfaced between parents' institutional-related challenges and their child's academic performance. No significant difference was observed regarding individual-related, instructional-related, and institutional-related challenges when grouped according to their profile variables. The study concluded that modular distance learning contributed fairly and minimally to students' science performance brought about by continued social and academic adjustment. School and parents' involvement in implementing modular learning is essential for improving the modality.

Authors: Shaharuddin Sharifah Syakila Syed , Harun Minah
Published: August 2022

The speech act is a study of pragmatics whereby utterances serve an essential function beyond verbal communication. It is an act of performing some activity through spoken words. In leadership, speech acts play a crucial role in the interaction between leaders and their followers. It not only conveys information but also initiates a desirable action or behaviour among the followers. Thus, leaders must be capable of utilizing different speech acts effectively to influence their followers to act or behave in a specific way and accomplish their leadership goals. This study has been undertaken in response to previous researchers who have found significant differences in speech acts of male and female leaders, with an objective to analyze the speech acts of female student leaders in a Malaysian secondary school according to Theory of Speech Acts by Bach & Harnish (1979). We collected data through in-depth interviews with three research participants who had been selected via purposive sampling. These participants were female students aged 17 years old with at least four years of leadership experience. After an in-depth qualitative analysis of interview data, we have demonstrated that speech acts of the research participants varied among constative, directive, commissive. Constatives, informative, assertive, and predictive acts. Among them, informative, assertive, and predictive speech acts dominated their utterances. In conclusion, the participants' speech acts indicated that, in general, they wished to be persuasive in their leadership roles and responsibilities.

THE IMPACT OF KNOWLEDGE MANAGEMENT PROCESSES ON TEACHERS’ DIGITAL SKILLS
Authors: Karageorgou Zoi
Published: August 2022

The impact of IR 4.0 has initiated a new paradigm shift for Greek educational institutions to ensure that all teachers are able to develop new teaching practices related to digital technologies. However, the majority of teachers use traditional teaching methods. Measures are needed to encourage teachers to acquire digital skills and integrate them into the educational process. Knowledge management processes can be used as an alternative strategy by schools to help teachers equip themselves with new skills and to meet the challenges ahead. Therefore, the aim of this study is to investigate whether knowledge management processes can be used as an alternative strategy by schools to equip teachers with the necessary digital skills. Hence, the four knowledge processes-acquisition, storage, distribution, and use-were related to teachers' digital skills. To this end, a quantitative study was conducted with a sample of 668 secondary school teachers from the Epirus region of Greece and analyzed using Partial Least Square Structural Path-Modeling (PLS-PM). The research results showed that knowledge management processes have a positive impact on teachers' digital skills.
