Published: November 2023

Inhaled corticosteroids are known to be relatively safe for long-term use in inflammatory respiratory diseases and it has been repurposed as one of the potential therapies for outpatients with coronavirus disease 2019 (COVID-19). However, inhaled corticosteroids have not been accepted for COVID-19 as a standard therapy because of its lack of proven benefits. Therefore, this study aimed to evaluate the effectiveness of inhaled corticosteroids in patients with COVID-19. Randomized controlled trials comparing the efficacy of inhaled corticosteroid treatment in patients with COVID-19 were identified through literature electronic database searches up to March 10, 2023. Meta-analyses were conducted for predefined outcomes, and the certainty of evidence was graded using the grading of recommendations, assessment, development, and evaluation approach. Overall, seven trials (eight articles) were included in this systematic review. Compared with usual care, inhaled corticosteroids was associated with significantly improved clinical recovery at 7 and 14 days in patients with COVID-19. In subgroup analysis, only budesonide showed significant efficacy in clinical recovery, whereas no significant benefit was observed for ciclesonide. Moreover, inhaled corticosteroids use was not significantly associated with all-cause hospitalization, all-cause mortality, admission to intensive care unit, or the use of mechanical ventilation. Our systematic review used evidence with very low to moderate certainty. Although based on limited evidence, our results suggest that inhaled corticosteroids treatment, especially budesonide, improves the clinical recovery of patients with COVID-19. More trials and meta-analyses are needed to assess the efficacy of inhaled corticosteroids for COVID-19 treatment.

Authors: Bölkény Ildi , Vadászi Marianna , Saliby Ammar
Published: November 2023

Green hydrogen, using renewable electricity that breaks down water molecules into hydrogen and oxygen, holds great promise for meeting global energy demand while contributing to climate policy goals. Interest in green hydrogen production technologies has increased considerably. This is because the potential uses of hydrogen cover many sectors, including power generation, manufacturing processes in steel and cement production, fuel cells for electric vehicles, and power grid stabilization. One possible use of green hydrogen is to blend it with natural gas and deliver it to end-users using existing natural gas pipeline storage and networks, thereby increasing performance and reducing emissions. In the case of underground storage of a hydrogen natural gas mixture, it is important to assess its impact on the reservoir beforehand, which rock permeability studies can do. This article deals with the theory of rock permeability testing for natural gas and natural gas-hydrogen mixtures.

Published: November 2023

The peel of a potato contains many biologically active compounds of various directions, which can be extracted for further use. The peel contains the largest amount of steroidal glycoalkaloids (SGAs) of potato, the extraction of which may be interesting for protecting plants from pests, as well as for the development of pharmaceuticals. The article studied the mechanisms that affect the accumulation and activity of SGAs in plants. Possibilities of their isolation from the potato peel by the acid method with the study of the effect of extraction factors on the yield of SGAs were studied. The object of the study was potato varieties Nakra and Kometa with the content of SGAs 422 and 251 mg/kg of potatoes. The concentration of compounds that passed into the solution was estimated by the spectrophotometric method. The possibility of reusing extracts on new peel masses has been established. When the extracts were concentrated by evaporation, the content of SGAsin them increased markedly. As a result of acid extraction, 200–1000 mg of SGAs/kg of peel (0.20–0.60 mg of SGAs/ml of extract) were extracted. Нydromodulus is a significant factor of acid extraction of SGAs. However, acid concentration and temperature can also influence the extraction process. The most optimal parameters for the process of extraction of steroidal glycoalkaloids with dilute sulfuric acid were established: acid hydromodulus 2.3, temperature 55 °C, acid concentration 0.1%, and extraction duration 30 min.

The aim of this research is the isolation and physicochemical characterization of water-soluble polysaccharides in the seeds of the turnip Brassica rapa of the family Brassicaceae cultivated in Uzbekistan.

For the first time, water-soluble polysaccharides were isolated from turnip seeds by sequential water extraction. Polysaccharides are deproteinized and separated by ion exchange chromatography, purified on a Sephadex G-100 column. Two polysaccharide fractions BSP-1-1 and BSP-2-1 were obtained. The results of IR spectroscopic studies showed that the isolated polysaccharides consist mainly of α-linked pyranose units. Analysis of the monosaccharide composition showed that the composition of the neutral polysaccharide BSP-1-1 is represented by monosaccharides in the following composition: ribose – 5.05%, arabinose – 56.38%, mannose – 5.87%, glucose – 8.63% and galactose – 24.05%. The composition of the anionic polysaccharide BSP-2-1 is represented by monosaccharides: ribose – 6.35%, arabinose – 60.15%, mannose – 7.19%, glucose – 4.12% and galactose – 22.16%. It was determined that the isolated polysaccharides consist mainly of arabinose (BSP-1-1 – 56.3%, BSP-2-1 – 60%) and galactose (BSP-1-1 – 24%, BSP-2-1 – 22%). Based on the data obtained, it can be assumed that the studied polysaccharides from the seeds of the turnip Brassica rapa belong to the type of arabinogalactans.

The purpose of the scientific work is to assess the quality of a set of scientometric indicators to determine the degree of truth of publication scientific collaborations. The paper presents the definition of a publication collaboration of scientists. The main types of collaborations are described: true and false. A list of external and internal alternatives (indicators) for their assessment has been formed. As an analysis of the system for evaluating scientific activity, a ninescreen diagram of the system for evaluating activities in the field of publication activity of the FSBEI HE “Nosov Magnitogorsk State Technical University” (NMSTU). From the analysis of the scheme, it can be seen that today there is a traditional system for evaluating publication collaborations. It has been determined that the existing system for assessing the degree of truth of publication collaborations must be supplemented with decisionmaking scenarios and an updated list of indicators for assessing links between the authors of scientific papers. For this, a group of experts (heads of scientific and educational organizations) was selected, who formed a list of external and internal alternatives (indicators) to assess the truth of publication collaborations of scientists of a higher educational institution. For the reliability of the results of the formation of the list of alternatives, it was decided that it was necessary to assess the competence and consistency of experts. The list of external alternatives for evaluating the validity of publication collaborations was used as the initial data for peer review. Coefficients were calculated to assess competence and consistency. It is concluded that the generated list of external alternatives is considered qualitative for assessing the degree of truth of publication collaborations.

Authors: Sitasiwi Agung Janika , Mardiati Siti Muflichatun , Melati Alfriyan Krisna
Published: November 2023

Daun mimba (Azadirachta indica) memiliki banyak manfaat dalam bidang kesehatan. Hasil pengujian yang sudah dilakukan menunjukkan bahwa pemberian ekstrak daun mimba dapat mempengaruhi sistem reproduksi pada hewan jantan, namun efek yang diberikan tidak signifikan terhadap organ testis. Ukuran senyawa yang terlalu besar diduga tidak dapat menembus blood-tissue barrier sehingga perlu dikemas dalam formula dengan ukuran yang lebih kecil, berupa nanopartikel. Tujuan penelitian ini adalah mengetahui pengaruh sediaan nanokitosan ekstrak etanol daun mimba (SNEEDM) terhadap histologis testis tikus putih. Penelitian ini menggunakan 32 ekor tikus umur 2 bulan dibagi menjadi 4 perlakuan yaitu K- (aquades 2ml), K+ (larutan sediaan nanokitosan 2ml). P1 (diberi sediaan nanokitosan dan ekstrak dengan perbandingan 1:0.5), P2 (diberi sediaan nanokitosan dan ekstrak etnaol daun mimba dengan perbandingan 1:1). Hasil penelitian menunjukkan pemberian ekstrak etanol mimba dalam bentuk nanopartikel kitosan berpengaruh tidak nyata terhadap bobot testis, diameter tubulus seminiferus dan skor kerusakan tubulus seminiferus namun berpengaruh nyata terhadap ketebalan epitel tubulus seminiferus (P<0.05), sehingga dapat disimpulkan bahwa pemberian SNEEDM berpengaruh terhadap penurunan ketebalan lapisan epitel tubulus seminiferus. Azadirachta indica have many health benefits. The results of tests that have been carried out show that the administration of neem leaf extract can affect the reproductive system in male animals, but the effect given is not significant to the testicular organs. The size of the compound that is too large is thought to be unable to penetrate the blood-tissue barrier, so it could be packed in a small size particles. The purpose of this study was to determine the effect of neem leaf ethanol extract nanocytosan preparation (SNEEDM) on the histology of white rat testes. This study used 32 rats aged 2 months divided into 4 treatments namely K- (2ml distilled water), K+ (treated by 2ml preparation of nanochitosan solution), P1 (treated by preparation of nanochitosan and neem leaf ethanol extract 1:0.5 in proportion), P2 (treated by preparation of nanochitosan and neem leaf ethanol extract with 1:1 in proportion). The results are the administration of neem ethanol extract in the form of chitosan nanoparticles had no significant effect on testicular weight, seminiferous tubule diameter and seminiferous tubule damage score but had a significant effect on seminiferous tubule epithelial thickness (P <0.05), so it can be concluded that the administration of SNEEDM has an effect on reducing the thickness of the seminiferous tubule epithelial layer.
Reconceptualizing the curation of prescribed learning resources in an immersive block teaching model
Authors: Thorpe Clare , St. Clair Honey Tanya , Wilson Erica
Published: November 2023

The presentation will describe how the curation of prescribed learning resources has been reconceived as an enabler of an immersive block teaching model. Contemporary higher education curriculum relies on high quality learning resources to engage students, to encourage them to adopt deeper learning approaches (Gledhil et al., 2017) and to support students’ academic adjustment to university (Owusu-Ageyman & Mugume, 2023). Little has been written about learning resources and reading lists within the digital transformation of higher education in the post-pandemic environment. The presentation will showcase a new way to position prescribed learning resources accessed as an integral feature of constructively aligned pedagogy within an immersive teaching model. Through the lens of an institutional case study at Southern Cross University, the presentation will show how prescribed learning resources delivered via integrated reading list technology are an enabling element of an innovative, student-centred, university-wide curriculum renewal project. At a time of increasing student expectations of teaching quality, academic, educational design and library staff need to review whether reading lists of learning resources are fit for purpose (Brewerton, 2014) and consider the cognitive load placed on students by reading (Barile et al., 2022). The presentation will outline the evidence-based, policy-led approach adopted by Southern Cross University and will demonstrate how learning resources and reading lists can contribute to student success. Prescribed learning resources and reading lists are now seen as pedagogical tools within the immersive teaching model, providing a variety of media-rich learning resources aligned to unit learning outcomes. Reading list parameters ensure that a manageable volume of learning is implemented, reducing cognitive load and barriers to participation. The approach to reading lists taken by Southern Cross University to empower immersive teaching practices provides a refreshed model for the use of prescribed learning resources in unit and curriculum design, development, and delivery.

Published: November 2023

This paper discusses the design process in the development of an undergraduate early childhood course. This design process was grounded in learning theory, using a team-based collaborative process to consider, develop and refine the course design. It started with a reflection on the learners and the learning environment. It then moved into an iterative process of investigation, creation and refinement of a new course that addresses the characteristics of the learners, the learning environment, authentic assessment and the learning outcomes holistically. This paper details the design process from initial conceptual thinking through to the final proposal ready for the University governance process and accreditation approval. Future directions could consider investigating the experience of all stakeholders involved in the process, as well as the student experience of the new course, to inform the process of collaborative course design.

Wilderness Ethics in the Anthropocene
Authors: Tongyang Liu
Published: November 2023

The concept of wilderness has been deconstructed with the arrival of the age of Anthropocene, so the wilderness ethics of the Anthropocene was once ignored. But in fact, what has been deconstructed is only the “natural” wilderness as pure nature, not the “untrammeled” wilderness. In addition, the environmental system corresponding to the traditional wilderness concept still exists, and is still the closest to the original natural environmental system. There is a debate on how to treat this environmental system in the age of Anthropocene, so it is necessary to clarify the concept of wilderness in the Anthropocene and rebuild the wilderness ethics. The wilderness ethics of Anthropocene is a responsive one, which calls for both sides to interact and blend without denying the autonomy of both sides: On the one hand, we should establish a holistic view of harmonious coexistence between man and the wilderness, basing on the ideological basis provided by the Anthropocene to break the binary opposition between culture and nature. The view does not include a sacred order. On the other hand, we should affirm the autonomy and uncertainty of the “untrammeled” wilderness. The wilderness ethics of the Anthropocene enlightens us that we should regulate the intervention of human and technology in a certain range when protecting the wilderness, respect “locality” and derive ecological wisdom from indigenous peoples.

Published: November 2023

Due to the adverse effects of synthetic chemical antioxidants, natural plant extracts, such as Penthorum chinense Pursh extract, have been demonstrated to possess antioxidative properties in Chinese sausages. Nevertheless, some physicochemical properties remain obscure. This study sought to determine the direct relationships between changes in pH, moisture, water activity, total viable count, color traits, volatile flavor compounds, and sausage quality. Therefore, P. chinense Pursh extract (PCPE) were added to Chinese sausage instead of synthetic chemical antioxidants. The results proved that the PCPE could reduce the a
w value and stabilize the pH and moisture. The total number of bacterial colonies in the 0.1 % and 0.3 % sample groups was 7 % lower than that in the blank group on the 35th day. The PCPE could also maintain an acceptable appearance in Chinese sausage; the 0.3 % PCPE group presented a better final a* value, and the 0.1 % PCPE group had a better b* value. Additionally, eight volatile flavor compounds (ROAV > 0.1), contributing to the flavor of Chinese sausage, were identified in the 0.3 % PCPE group by the ROAV analysis. Overall, the P. chinense Pursh extract could be a potential alternative to synthetic chemical antioxidants in the production of Chinese sausages.

A mini review on synthetic and biosurfactants: origin and structure, physicochemical properties, applications, cost of production, toxicity, biodegradability and environmental effects
Authors: Abdel-Rahem Rami A.
Published: November 2023

A comparison is made between synthetic and biosurfactants in terms of their origin, structure, physico-chemical properties, applications, production costs, toxicity, biodegradability and environmental impact. It is shown that the chemical structure of surfactants synthesised by living organisms is more complicated than that of those produced by classical methods. The reduction in water surface tension induced by synthetic and biosurfactants is almost the same. Due to their origin and structure, biosurfactants are preferred in medical, cosmetic and food applications, mainly because they are less toxic than synthetic surfactants. Synthetic surfactants require more time and special environmental conditions to start the biodegradation process compared to biosurfactants, which can easily start biodegradation under normal physical conditions. This mini-review highlights this new category of surfactants (biosurfactants). It also provides a comparison between synthetic and biosurfactants is provided using the available data reported in the literature.

Abstract. The research focuses on addressing the challenges of evaluating the effectiveness of modern power systems in countries with different configurations. Given the growing interest of con-sumers in the impact on the electricity supply schedule, the research is divided into two main parts. Firstly, a model has been developed to assess the operational efficiency of the power system. Secondly, a method for analyzing the efficiency of the energy system has been developed, based on a model of changes in energy system quality indicators. The presented model takes into account energy system characteristics such as the probability of network failure, normalized frequency of electricity, and the volume of consumed and supplied electrical energy. It is expected that this model will provide a more accurate assessment of the efficiency of the energy system under normal operating conditions. Additionally, a method for analyzing the operational efficiency of the energy system has been developed, based on a model of changes in energy system quality indicators. The uniqueness of this method lies in the introduction of a new comprehensive indicator of energy system efficiency, deter-mined by the convolution method of partial indicators, namely: the volume of electricity supply, supply quali-ty, and electricity supply efficiency. The reliability of the model is confirmed by calculations of the daily schedule of supply and load Keywords: electric power system, electricity supply efficiency, evaluation of power supply system effi-ciency, electricity indicators, load schedule, consumer management, electricity supply quality.

Latar Belakang: Persentase status gizi Provinsi Jawa Barat terdiri dari 1,4% status gizi sangat kurus dan 6,1% status gizi kurus, maka diperlukan intervensi kepada anak-anak usia sekolah untuk mencegah status gizi buruk di wilayah Desa Kadumangu Metode: Penelitian ini adalah penelitian deskriptif dengan rancangan cross sectional. Sampel diambil menggunakan teknik purposive sampling. Kriteria sampel yaitu laki-laki dan perempuan usia 6-12 tahun. Tahap pertama pengambilan data adalah pengambilan data tinggi badan, berat badan, dan FFQ. Tahap kedua adalah pengambilan data tinggi badan dan berat badan setelah sosialisasi. Hasil: Persentase perubahan berat badan setelah sosialisasi yaitu 83% berat badan naik, 13% tetap, dan 4% turun. Frekuensi makan anak-anak kurang dari 3 kali dalam sehari. Kebiasaan makan anak-anak adalah mengonsumsi beras (karbohidrat), daging ayam (lauk hewani), tempe serta tahu (lauk nabati), bayam (sayur), dan apel (buah). Jajan yang paling sering dikonsumsi adalah minuman instan dan serbuk serta makanan manis dan gurih. Hasil uji paired sample test menyatakan sig.(2 tailed) sebesar 0,06. Kesimpulan: Secara deskriptif ada perbedaan rata-rata nilai berat badan sebelum dan sesudah sosialisasi. Namun berdasarkan paired sample test, sig.(2 tailed) p > 0,05, sehingga sosialisasi tidak berpengaruh terhadap status gizi anak.
