Authors:   MIREA-Russian technological university, Gorbatova Anastasiya V. , Buryakov Arseny M. ,   MIREA-Russian technological university
Published: March 2024

An optimized design of a spintronic terahertz emitter has been developed, based on a bilayer Co/Pt structure with an integrated distributed Bragg reflector. The incorporation of the Bragg mirror between the Co/Pt structure and the silicon substrate enhances optical absorption in the ferromagnetic layer, thereby amplifying spin current generation and, consequently, THz signal. A model was developed for calculating the optical absorption in the ferromagnetic layer of the spintronic emitter, taking into account the parameters of the Bragg mirror (layer thicknesses, period) based on the superlattice structure [TiO2/SiO2]N. This model is grounded on the solution of Maxwell's equations for electromagnetic waves using the COMSOL Multiphysics software. The effect of anti-reflective dielectric coatings on the level of optical absorption in the ferromagnetic layer was also analyzed. The study confirmed that using the optimized Bragg mirror is sufficient for achieving optimal absorption.

The work devoted to study of the electrical properties and morphology of Langmuir-Blodgett films of modified graphene oxide (GO). The Langmuir-Blodgett method was used for studying of formation process of Langmuir monolayers formed on the subphase contained dissolved ions of tin chloride salt. The compression isotherms of monolayers formed in the presence of tin ions shifted towards larger occupied areas. Langmuir monolayers of graphene oxide formed under various conditions were transferred on solid substrates and studied by atomic force microscopy and voltammetry. It has been established that the presence of tin ions in the aqueous subphase leads to changes in the morphology of the formed films. Thus, the average roughness and surface area of such films increased from 0.2 nm and 0.04 μm2 to 5.4 nm and 0.46 μm2, respectively. The presence of tin ions dissolved in the aqueous subphase influenced the type of current-voltage characteristics of the films under study. The maximum reverse current increases from 075 nA to -0.3 nA and the resistance increases from 11 GOhm to 700 GOhm. Temperature annealing of the graphene oxide film at 300°C leads to a decrease in the maximum forward current and an increase in the reverse current from 0.0407 nA and -0.071 nA to 0.0065 nA and 0.0616 nA, respectively. For a film formed in the presence of ions in the subphase, annealing does not affect the maximum forward current, and the current of the reverse branch of the current-voltage characteristic increases from -0.1669 nA to 0.0468 nA.

The propagation channel is significantly modified in the case of 5th Generation New Radio radio access technology (5G NR) in space communication systems. In particular, large delays occur with respect to the terrestrial propagation channel, and signal attenuation increases, resulting in a lower signal-to-noise ratio (SNR). The Doppler shift of the carrier frequency is also significantly increased due to the high velocity of the spacecraft (SC) relative to the user equipment (UE). The aim of the work is to investigate the decoding capability of the physical channels and signals of the 5G NR system in case of its application in satellite communication systems (SCS), as well as to calculate the performance of such a system to assess the applicability of 5G NR in SCS. The ability to correctly decode signals and channels depending on SNR is evaluated using mathematical modelling of 5G NR signal and channel shaping in conjunction with the Quasi Deterministic Radio Channel Generator (QuaDRiGa) model. The research within the paper draws conclusions on the applicability of 5G NR radio access technology in a space communications environment.

Published: March 2024

BACKGROUND: Contemporary Russian system of complex rehabilitation and habilitation of disabled people is in the process of transformation. Application of the biopsychosocial approach through the use of the International Classification of Functioning, Disability and Health as a planning methodology Implementation and evaluation of rehabilitation measures make it possible to implement the key principles of rehabilitation: earlier, comprehensiveness, continuity, individual approach.
AIM: To substantiate the possibility of implementing a modern regional interdepartmental model of integrated rehabilitation in a specialized centre, taking into account the structure of disability and the formation of new target rehabilitation groups.
MATERIALS AND METHODS: Analysis of the dynamics of primary disability of the adult population, description of the structural and functional model of the creation and operation of a multidisciplinary rehabilitation center in conditions of interdepartmental cooperation.
RESULTS: The structure of primary and secondary disability in the Perm Region is characterized by the predominance of persons with disabilities of groups 1 and 2 (60%) of working age, whose disability is caused in 30% of cases by malignant neoplasms. This determines the content of individual rehabilitation and habilitation programs to be developed for persons with disabilities and should be reflected in the development of appropriate infrastructure in the region. Modernization of the whole system, involving the use of targeted rehabilitation groups, ensuring continuity of medical and social activities in the relevant organizations and creating conditions for their continuation in the place of residence, should contribute to the effectiveness of rehabilitation activities in general.
CONCLUSION: Recommendations on improvement of the system of complex rehabilitation in the conditions of a specialized center on the basis of interdepartmental cooperation have been proposed as a result of the research.
Analysis of newly diagnosed disabilities dynamics among medical workers in the Irkutsk region from 2003 to 2021 period
Authors: Rybchenko Natalya V. , Vladymyrova Oksana N.
Published: March 2024

BACKGROUND: The specificity of the professional activities of medical workers is one of the main reasons for their high morbidity, including due to the influence of unfavorable factors in the working environment. The need to reduce labor losses in the industry necessitates the study and analysis of the disability status of doctors within the framework of long-term observation.
AIM: A study of the dynamics of primary disability indicators of doctors working in their specialty in the Irkutsk region at the time of examination, in comparison with the primary disability of the adult population of the Irkutsk region for 19 years from 2003 to 2021.
MATERIALS AND METHODS: An observational retrospective continuous study of primary disability indicators of working doctors in the Irkutsk region for 19 years (2003–2021) was conducted. Analytical, statistical, data copying, and expert assessment methods were used.
RESULTS: During the study period, 1,703 people working as doctors in the Irkutsk region were recognized as disabled for the first time. The average long-term intensive rate of primary disability of doctors for 19 years averaged 75.4 (±7.55) per 10 thousand working doctors, which is 17% lower than the same indicator for the adult population of the region. The following diseases took the first place among doctors during 2003–2011: diseases of the circulatory system, and over the past ten years since 2012 — malignant neoplasms.
CONCLUSIONS: The level of primary disability in physicians responds more quickly and sensitively to changes in social legislation, and is less affected by changes in the number of physicians in the region than the corresponding rates in the adult population of the region as a whole. The nosological structure of doctors disabled mainly coincides with the indicators of the adult population.

Published: March 2024

The current research focus at Chukchi Boardland (CB) revolves around sediment stratification and crustal structure, but investigations into deep stress fields and mantle dynamics are limited. This article presents a study on the anisotropic characteristics of the CB. Shear-wave splitting measurements were conducted using the transverse energy minimization at six stations recovered from the 11th Chinese National Arctic Research Expedition. The observation period for these six stations ranged from 2 August 2020 to 8 September 2020. The results demonstrate significant anisotropy within the CB, with the fast shear-wave polarization direction ranging from N60°E to N70°E. The time delays between fast and slow shear waves were found to be ∼0.7 s. By comparing the anisotropy observed at the CB with that at land stations in Arctic Alaska, this study suggested that the genesis of anisotropy beneath the CB was related to the formation of the Amerasian basin. The tectonic processes of rifting during basin evolution and midocean ridge spreading led to the development of anisotropy in the lithosphere beneath the CB during expansion.
Along-Strike Variation of Rupture Characteristics and Aftershock Patterns of the 2023 Mw 7.8 Türkiye Earthquake Controlled by Fault Structure
Authors: Wan Zhifan , Dong Rendong , Wang Dun , Xu Shiqing , Wang Zhifeng , Wang Qi
Published: March 2024

On 6 February 2023, an Mw 7.8 earthquake occurred along the East Anatolian fault zone (EAFZ) in southeastern Türkiye, representing the strongest earthquake in the region in nearly 80 yr. We investigate rupture characteristics and aftershock patterns of the earthquake through focal mechanism calculation, backprojection analysis, and finite-fault inversion. The results show bilateral rupture propagation of the mainshock with transient supershear speed in the southwest portion of the EAFZ, as well as shallower coseismic slip and abundant normal-faulting aftershocks in the same portion. We attribute these earthquake behaviors to the along-strike variation of fault structure of the EAFZ, which features a more complex fault geometry accompanied by numerous short normal faults in the southwest portion. These results shed light on fault segmentation, rupture speed variation, and slip partitioning along the EAFZ, advancing our understanding of fault structural control on earthquake behaviors in a complex multisegment fault system.

As the number of Spanish-speaking patients with cancer in the USA grows, it is vital that reliable online breast cancer information is available in Spanish. The main objective of our study was to determine the quality and reliability of online videos in Spanish regarding breast cancer. We conducted a YouTube search using the phrase “cancer de mama” (breast cancer) and graded their quality and reliability using the Journal of the American Medical Association (JAMA) Benchmark Criteria, Global Quality Score (GQS), and the Modified DISCERN Questionnaire. Videos were characterized by descriptive variables. Videos were primarily from Spain (36.4%) and Mexico (17.9%). ‘professional’ videos had the highest JAMA mean rank (99.53), the highest GQS mean rank (102.86) and the and second-highest DISCERN (101.10) mean rank. ‘Personal’ videos, by contrast, had the lowest mean rank values for GQS (72.28) and DISCERN (68.83) scores. A significant majority of online breast cancer videos in Spanish were of poor quality and reliability. ‘Professional’ videos are of higher quality and reliability than videos of other typologies; however, they have a limited range of content. In addition, a small percentage of videos were uploaded from the USA.
El desplazamiento ambiental en Colombia: Retos y avances de la Sentencia T-369 de 2021 de la Corte Constitucional
Authors: Ramírez Cerón Rosa Stephanie
Published: March 2024

In the Judgment T-369 of 2021, the Constitutional Court of Colombia reviews a case of human displacement caused by the diversion of the Cauca River for the Pescadero Ituango Hydroelectric Project (Hidroituango). This constitutional decision highlights the various routes established by jurisprudence for managing environmental displacement. However, this research aims to demonstrate that the existing protocols for addressing environmental displacement are not sufficient, especially considering that the incorporation of this special category of human migration into the Colombian legal system is necessary. Giving prominence to these concepts would facilitate the creation of a comprehensive care pathway focused on every stage of the environmental catastrophe generated by human movement.

National-Populism, Post-Truth, and the Logic of Postmodernism: A Multidisciplinary Insight into the Crisis of Liberal Democracy
Authors: Zeli Alfredo
Published: March 2024

2024 is said to be a decisive year for liberal democracy in the world. The national-populist phenomenon that has been on the rise in recent years occasions renewed and sustained academic debate on the existential challenges faced by liberal democracy. It is a paradigmatic assumption of the liberal mainstream that the rise of national-populist leaders and their constituency pose a fundamental threat to democratic survival. But are national-populism and the Western model of liberal democracy divorced in any essential way? If, as the liberals maintain, national-populism rests and thrives upon the post-truth condition of societal fragmentation and individual psycho-cognitive isolation characterizing contemporary society, we must investigate whether this condition is something foreign to liberal democracy and therefore removable as such. By mobilizing a multidisciplinary corpus, this article shows that postmodernism, defined as the cultural superstructure of consumerist capitalism, is what underpins and perpetuates the interrelated phenomena of infinitely increasing social fragmentation and individual isolation. In the most advanced contemporary stage, called “late postmodernity,” the subjects of Western consumerist capitalist societies are purely driven by a hedonist-narcissistic pleasure principle that defuses all potential for the radical contestation of the existing hegemonic power structure of the liberal-democratic state. The post-truth condition, of which national-populism is an outgrowth, poses no essential threat to liberal democracy as long as both are sustained and promoted, at the structural level, by the hegemonic mode of production.
De la tutela antidiscriminatoria a la protección de situaciones de vulnerabilidad. Posibilidades y límites en el derecho de la Unión Europea
Authors: Rodríguez Sanz de Galdeano Beatriz 
Published: March 2024

En el presente artículo se realiza una aproximación a la construcción dogmática del concepto de vulnerabilidad llevada a cabo desde la Filosofía del Derecho, con el fin de analizar la virtualidad de esta nueva categoría en la interpretación y aplicación del derecho positivo y, muy en particular, en la garantía de la prohibición de discriminación en el ejercicio de cualquier derecho. Se presta especial atención a la utilidad de este nuevo concepto para superar algunas limitaciones del derecho discriminatorio, que todavía se encuentra anclado en la identificación de grupos objeto de discriminación y pierde de vista la toma en consideración de situaciones particulares e individualizadas de discriminación y la necesidad de asegurar un ejercicio efectivo de los derechos.
Sobre la posibilidad de celebrar actuaciones procesales digitales (en particular las vistas) en el orden social de la jurisdicción tras los últimos vaivenes normativos
Authors: Tascón López Rodrigo
Published: March 2024

En la actualidad, el Orden Social de la Jurisdicción padece una situación que dista mucho de ser la ideal, con retrasos que a fuer de excesivos resultan injustificados, con riesgo de acabar por lesionar el derecho fundamental a la tutela judicial efectiva, como ha tenido que declarar el máximo intérprete de la Constitución. Frente a esta situación, y junto con otras soluciones posibles (de forma señera, la mayor dotación de medios materiales y humanos), la tecnología se presenta como un bálsamo de fierabrás, potencial remedio que puede ofrecer soluciones para (casi) todos los males que sufren los tribunales laborales.En concreto, el presente ensayo plantea para el debate si la celebración de actuaciones procesales digitales (en especial, aun cuando no solo, las vistas) podría contribuir a mejorar el desenvolvimiento (y la celeridad) de los Tribunales laborales, llegando a una conclusión afirmativa, aun cuando matizada  especialmente a la vista de las últimas reformas habidas en materia procesal.

Published: March 2024

Aim: Venous blood derivatives (VBDs) have been suggested as substitutes for Fetal Bovine Serum (FBS) to improve the clinical transition of cell-based therapies. The literature is not clear about which is the best VBDs substitute. The present study aimed to evaluate the influence of VBDs on cell viability and describe a new method to seed these cells in a 3D Platelet-Rich Fibrin (PRF). Methods: Blood was processed to obtain Platelet-Poor Plasma from PRF (P-PRF), Human Serum (HS), Platelet-Poor Plasma from PRP (P-PRP), activated-PRP (a-PRP), and Platelet lysate (PL). Cells were supplemented with each VBD at 10% and FBS at 10% was the control. Cell viability (fibroblast 3T3/NIH) test was evaluated with MTT assay in two ways: i) cell-seeded and expanded with VBD; ii) cell-seed with FBS and expanded with VBD. To seed the Fibrin construct, cells were suspended in PBS and dropped into the blood sample before performing Choukroun’s protocol for PRF. Constructs were cultured for 7 days in VBD supplements and FBS. Histological and Immunohistochemical analysis with vimentin was performed. Cell viability was analyzed by one-way ANOVA. Results: VBD’s production time was very heterogeneous. Cells expanded in HS and a-PRP has grown faster. VBD-supplemented culture media provided cell culture highly sensible to trypsin/EDTA 0.25%. Cells seeded and expanded with VBD presented viability comparable to FBS in HS, a-PRP, and P-PRP (p>0.05) and lower in P-PRF and PL groups (p<0.05). The viability of cell seed with FBS and expanded with VBD was similar between P-PRF, a-PRP, PL, and FBS (p>0.05) and lower in HS and P-PRP (p<0.005). PRF-seeded cells showed a positive expression of vimentin and were able to maintain all cells supplemented with VBD. Conclusion: VBD supplements were able to maintain fibroblast cells in 2D and 3D cultures. The new method of the fibrin-cell construct was efficient to insert the cells into the fibrin network.

Published: March 2024

The maintenance of adequate fluoride (F) concentration in the public water supply is fundamental for ensuring that the community use of F can reach the maximum benefit for caries control and minimum risk for dental fluorosis. Thus, surveillance systems must use accurate and valid analytical methods to determine F concentration and, according to the literature, give preference to the ion-specific electrode (F- ISE) analysis. Aim: The objective of this study was to compare the accuracy of the ISE and SPADNS methods in the determination of the F concentration in the same water sample. Methods: Duplicate water samples were taken from 30 sampling sites in the municipality of Maringá, state of Paraná, monthly for 12 months, totaling 276 samples. An aliquot was analyzed by the FOP-UNICAMP Oral Biochemistry laboratory, using the F- ISE method, and the other one, by the SANEPAR laboratory in Maringá/PR, using the SPADNS method. Descriptive analysis and Pearson’s correlation test were applied, with a significant level of p<0.05. Results: Results were expressed as ppm F (mg F/L), and a very strong positive correlation (r= 0.91; p<0.001) was detected between the two methods of analysis. Conclusion: Our findings suggest that the determination of f luoride concentration in water can be made with accuracy by the SPADNS method, a standardized analysis protocol.
Examining the practices and success of community-based tourism: A study at Barru Regency, Indonesia
Authors: Junaid Ilham
Published: March 2024

Community-based tourism (CBT) is a way to encourage the community to get involved in tourism, and its success depends on the level of participation. Although many academics have discussed CBT, such a concept needs evaluation related to its implementation and how the community benefits. This paper aims to (1) identify the practices of CBT and factors affecting the conduct of beach tourism; (2) evaluate the success of CBT from the perspective of the local people. This paper employs the conceptual framework of success criteria for CBT by utilising qualitative data from in-depth interviews and observations at Ujung Batu Beach, Barru Regency. The research reveals that the practice of beach tourism consists of two, approaches: existing condition management and proposed people management. Six factors affect the conduct of tourism: boat parking by the fishermen, waste management, limited community participation, the natural condition of the coastal area, the existence of the local organisation and the availability of facilities. There should be more efforts to achieve the goals of CBT, including support from the coastal residents, promotion of uniqueness and environmental conservation. This paper contributes to advancing the knowledge of CBT from the perspective of beach tourism.
Domination criticism and freedom criticism on flood news in online media from a Foucauldian view
Authors: Christantyawati Nevrettia , Izzati Yuyun Wahyu , Dayanti Liestianingsih Dwi
Published: March 2024

This article discusses the issue of flood disaster polemics in online media using McKerrow’s critical rhetorical theory analysis, with the main aim of getting closer to discourse formations that have not been discussed in previous research on political interest contestation. This research uses Fairclough’s critical discourse analysis method to reveal flood news articles from 2019-2021 on Tirto.id. Meanwhile, the Foucauldian perspective in this study is used as a review of McKerrow’s critical rhetoric to analyze power, right and truth. Furthermore, this triangulation is explained in two criticisms, namely, criticism of domination and freedom in the online media Tirto.id in reporting on the flood. This study found that in terms of power, Tirto.id discusses criticism of power as a struggle for power in the social status of the upper and lower middle classes. Dominance tends to appear in social disparities and discrepancies in the effects of development on poor communities and the surrounding ecosystem. In terms of rights, Tirto.id discusses demands for ecological justice for lower middle class society. Finally, in terms of truth, the discourse about flood victims includes the lower classes as a result of land grabbing. This study concludes that criticism of domination shows that the government is not very serious about the concept of ecological justice for all groups. Criticism of freedom shows that Tirto.id expresses satire that floods are only suffered by poor people, not rich people.

Authors: Pratiwi Oktafiani C. , Marwah Sofa , Ramadhanti Wita
Published: March 2024

Pekalongan batik sub-culture development is influenced by three cultures namely Javanese, Chinese and Arabic. Most studies of batik use a cultural and socioeconomic analysis by focusing mainly its cultural aspects. This research aims to analysis transformation of social and economic assets, by using a different perspective namely cross-cultural theory and democratization framework in order to explain the political economic contestation among the entrepreneurs. This research uses Robert Dahl’s conceptual framework regarding the development of democracy and only uses three of the seven relevant aspects, namely: (a) representation, (b) diversity, and (c) conflict. Case studies as a qualitative methodology are used with in-depth interview techniques, observation and literature reviews as data collection tools. The results of this study are, Pekalongan batik sub-culture has formed a kind of long acculturation formation in the cultural perspective, but secondly it also contributes to develop a kind of political contestation, conflicts and gender-bias political practices This study concludes that regional autonomy and decentralization policies have created space for political contestation and opened up opportunities to transform the social/economic capital of batik entrepreneurs as assets for political contestation and have even raised the issue of identity politics.

Nausea and vomiting during pregnancy are common occurrences in the first trimester. This can be attributed to an increase in estrogen and progesterone hormones produced by human chorionic gonadotropin (HCG) in the placenta. Various therapies can be employed as antiemetics in pregnant women, and one of them is traditional therapy involving the administration of ginger extract. This research design uses a literature review methodology, gathering data from international and national journals that meet the inclusion and exclusion criteria. The databases utilized include Google Scholar, PubMed, and Garuda. To understand the effectiveness of ginger extract administration as an antiemetic in pregnant women. The methodology employed is a literature review, utilizing the Google Scholar database to search for articles published between 2013 and 2023 in both Indonesian and English languages. Ginger can reduce nausea and vomiting by modulating gastrointestinal effects such as smooth muscle contractions and stimulating gastric motility. It inhibits 5-HT3 receptors in the central nervous system, hampers carminative effects, reduces cisplatin effects, and has effects similar to dimenhydrinate. Administering ginger infusion twice a day for 4-7 days has shown a decrease in the occurrence of nausea and vomiting in pregnant women. Additionally, ginger aromatherapy with 5 ml for four consecutive days can reduce the incidence of nausea and vomiting in pregnant women with hyperemesis gravidarum. Ginger extract can reduce nausea and vomiting in pregnant women.

Design of Additional Dissipative Structures for Seismic Retro-fitting of Existing Buildings
Authors: Bergami Alessandro Vittorio
Published: March 2024

This paper presents an innovative approach for improving the seismic protection of existing structures by introducing an additional dissipative structure (ADS). The seismic energy impacting the building can be dissipated through the contribution provided by the ADS, thereby reducing the need for the existing building to ensure its seismic capacity. This retrofitting technique is well-suited for structures facing architectural restrictions or challenging-to-update elements. It can help address foundation issues by applying loads to new external components. This paper describes the design of the ADS and proposes a displacement-based design procedure. The design process involves a non-linear static analysis and a simple procedure that must be iteratively repeated until the retrofitting target is achieved. This approach is simple and computationally efficient and can also be used for complex and irregular structures. Such structures are frequently encountered, and existing structures often exhibit unusual geometries and materials requiring extensive numerical modeling. The efficacy of the technique was evaluated using the case studiy of a school building located in central Italy. The results of numerical analyses indicated that owing to the ADS’s contribution, the seismic capacity of both buildings was enhanced, addressing the challenges associated with complex foundation interventions.

Newborn screening (NBS) is hailed as a public health success, but little is known about what happens to these children after diagnosis. There has been difficulty gathering long-term follow-up (LTFU) data consistently, reliably, and with minimal effort by state NBS programs from clinicians. Six programs have been working towards a core minimal LTFU dataset, starting with data elements proposed by the Advisory Committee on Heritable Disorders in Newborns and Children’s Follow-up and Treatment workgroup (ACHDNC FUTR). This minimal data set could begin to address the impact of early diagnosis by NBS. After three rounds of data collection and revision to a data collection tool that defines the minimal LTFU data elements, the group agreed that it was most important for the dataset to capture two items for the denominator--diagnosis and if the child moved or died—with three outcomes: if the child was still alive, if the child had contact with a specialist, and if they received appropriate care specific to their diagnosis within the year. All six programs were able to provide these data. In 2022, about 83.8% (563/672) of the children in these LTFU programs were alive, 92.0% saw a specialist, and 87.7% received appropriate care.

Published: March 2024

Emerging pollutants (EPs) encompass natural or synthetic substances in the environment that pose potential risks but have only recently been recognized or monitored. EPs consist of various categories including pesticides, pharmaceuticals, hormones, mycotoxins, and endocrine disrupting chemicals (EDCs). Through several pathways, EPs can access food, potentially leading to health impacts when their safe concentrations are exceeded. Milk, being a highly nutritious and a heavily consumed food product by many consumers of different ages, is a crucial food matrix where EPs should be regularly monitored. In literature, large number of studies was dedicated for the determination of different EPs in dairy milk, employing different analytical techniques. Chromatographic based techniques were the most prevalent means for analysis of EPs in milk, which demonstrated significant efficiency, sensitivity and accuracy for this specific purpose. Prior to chromatographic analysis, extraction of EPs from a complex matrix like milk, is essential. This review comprehensively covers relevant research papers on extraction and subsequent detection and determination of EPs in milk by chromatographic methods from 2018 and until 2023.

Entamoeba histolytica, throughout its lifecycle, encounters a variety of stressful conditions. This parasite possesses Heat Shock Response Elements (HSEs) which are crucial for regulating the ex-pression of various genes, aiding in its adaptation and survival. These HSEs are regulated by Heat Shock Transcription Factors (EhHSTFs). Our research has identified seven such factors in this parasite, designated as EhHSTF1 through EhHSTF7. Significantly, under heat shock condi-tions and in the presence of the antiamoebic compound emetine, EhHSTF5, EhHSTF6, and EhHSTF7 show overexpression, highlighting their essential role in gene response to these stressors. Currently, only EhHSTF7 has been confirmed to recognize the HSE in the promoter of the EhPgp5 gene (HSE_EhPgp5), leaving the binding potential of the other EhHSTFs to HSE yet to be explored. Consequently, our study aimed to examine both in vitro and in silico the oligomeri-zation and binding capabilities of the recombinant EhHSTF5 protein (rEhHSTF5) to HSE_EhPgp5. The in vitro results indicate that the oligomerization of rEhHSTF5 is concentration-dependent, with its dimeric conformation showing a higher affinity for HSE_EhPgp5 than its monomeric state. In silico analysis suggests that the alpha 3 α-helix (α3-helix) of the DNA-binding domain (DBD5) of EhHSTF5 is crucial in binding to the major groove of HSE, primarily through hydro-gen bonding and salt-bridge interactions. In summary, our results highlight the importance of oligomerization in enhancing the affinity of rEhHSTF5 for HSE_EhPgp5 and demonstrate its abil-ity to specifically recognize structural motifs within HSE_EhPgp5. These insights significantly contribute to our understanding of one of the potential molecular mechanisms employed by the parasite to efficiently respond to various stressors, thereby enabling successful adaptation and survival within its host environment.

Published: March 2024

In the drive towards environmental restoration and sustainable energy solutions, effective utilization and management of agricultural crop residues are vital to mitigate greenhouse gas (GHG) emissions and waste accumulation. Converting biogenic wastes into biofuels and bioproducts has the potential to tackle the energy crisis and contribute to environmental remediation. In this investigation, teff husk, primarily generated in Ethiopia during teff production within the agro-industrial sector, is used as the feedstock for the slow pyrolysis process. In Ethiopia, it is estimated that over 1.75 million tons of teff husk are generated annually, with a significant portion being incinerated in the fields, resulting in substantial environmental pollution. This study focuses on assessing teff husk as a potential material for slow pyrolysis, a crucial stage in biochar production, to tap into its biochar-producing potential. To determine the composition of the biomass, the teff-husk was initially analyzed by thermogravimetry. The significant presence of fixed carbon indicates that teff husk is a viable candidate for pyrolytic conversion into biochar particles. The process of slow pyrolysis took place at three varied temperatures—specifically, at 400, 450, and 500 °C. Process parameters of slow pyrolysis such as reaction time, temperature, and heating rate were enhanced to obtain maximum biochar yields. The highest biochar yield of 43.4 wt% was recorded at optimized reaction time, temperature, and heating rate of 120 min, 400 °C, and 4.2 °C/min, respectively. Furthermore, biochar's physicochemical, SEM-EDX, FTIR, and TGA characterization were performed. The thermal stability and carbon content of biochar were found to rise at higher temperatures. Unlike fuel recovery, the results suggest that teff-husk can be used as a feedstock for biochar production.
