Students’ Perceptions of Biology Teachers’ Enacted Pedagogical Content Knowledge at Selected Secondary Schools in Lusaka Province of Zambia
Authors: Mapulanga Thumah , Nshogoza Gilbert , Yaw Ameyaw
Published: January 2023

Since teachers’ pedagogical content knowledge (PCK) plays a vital role in attaining educational goals, it has become a favourable construct in science education research. Because students are more perceptive when evaluating teachers, this quantitative survey examined students’ perceptions of biology teachers’ enacted PCK (ePCK). The sample consisted of 319 students from six secondary schools in three districts of Lusaka province, Zambia. Data were collected using a Likert- scale questionnaire called “students’ perceptions of teachers’ enacted PCK” questionnaire. It had a Cronbach’s alpha value of 0.842, indicative of good reliability. Data were collected on six ePCK components: curricular saliency, what makes the subject easy or difficult to understand; conceptual teaching strategies; representations; students’ prior knowledge; and assessment. The findings revealed that the students perceived that their biology teachers’ ePCK was moderate (M=3.61, SD=0.47). While the component ‘students’ prior knowledge’ was the most enacted (M=4.01, SD=0.73), while ‘what makes the subject difficult to understand’ was the least enacted component (M=3.01, SD=0.77). Statistically significant differences were observed in students’ perceptions pertaining to the variables grade level and type of school but not gender. These findings suggest that students’ perceptions of the teachers’ ePCK may highlight areas that teachers may reflect on to improve their PCK and, hence, students’ learning. The implications of these findings on teaching and learning were discussed. The study recommends using students’ perceptions to evaluate teachers’ knowledge and the general teaching-learning process.

The objective of this research was to study the effects of size and spat origin of farmed Mytilus galloprovinciallis in mussel longlines in the east of Bou-Ismail Bay (central coastal Algeria, south-western Mediterranean). The study was conducted from October 2017 to July 2020 in the east of Bou-Ismail Bay. The mussel spat were obtained from four origin sites (Tlemcen, Tenes, Ain Tagourait and the study site) and were seeded on three spat sizes (10–30, 30–60 and >60 mm). The production performance of this species was analysed on 284 random mussel plots using average physical product (APP), gain and loss rates, condition index (CI), percentage of edibility (PE) and shell thickness index (STI). Apart from the CI and loss rate, the performance indicators showed significant differences according to spat size and source (p < 0.05). Overall, the highest APP (4.3) was recorded for the small seeded mussels (10–30) mm and for those originating from Tlemcen, near finfish cages (APP = 4.14). These individuals exhibited more efficient growth and physiology for commercial size and performed better than the spat collected at the study site. The results can be considered a valid contribution to best farming practice for optimising the production of this species in Algeria. It also contributes to the development of integrated multitrophic aquaculture (IMTA) methodology, which is suitable for use in the oligotrophic Western Mediterranean.

Published: January 2023

In this study, monthly heavy metal concentrations in the whole-body tissue of Patella caerulea (Mediterranean limpets), a bioindicator species living in the coastal zone of the Gulf of Izmit (Marmara Sea), were examined for the first time. The mean metal concentrations in Patella caerulea (mg kg-1 dw) were 2.01–5.74 Cd, 2.45–12.90 Cu, 0.74–1.95 Pb, 21.12–109.57 Zn, 16.31–154.67 Ni, and 1120.67–3086.00 Fe. Cd levels in all months and Pb levels in October and November were found to be above the safe limits set by international organizations. The estimated daily intakes and estimated weekly intakes determined for each heavy metal were below the acceptable daily intakes and provisional tolerable weekly intakes. However, the target hazard quotient and total target hazard quotient values calculated for Cd, Ni, and Fe were found to be higher than 1. The carcinogenic risk value was also found to be high.

Published: January 2023

There is very limited aquaculture research on candidate probiotics and their effects on fish physiology. In this study, acute applications of four different molecularly identified bacterial species – Brevibacillus brevis FD-1 (A), Pseudomonas fluorescens FDG-37 (B), Bacillus sphaericus FD-48 (C), and B. amyloliquefaciens TV-17C (D), with potential in aquaculture, were tested in rainbow trout (Oncorhynchus mykiss) under static conditions. Physiological changes in blood tissue [hematological indices: erythrocyte count (RBC), leukocyte count (WBC), hemoglobin (Hb), hematocrit (Hct), platelet count (PLT), mean cell hemoglobin concentration (MCHC), mean cell hemoglobin (MCH), and mean cell volume (MCV)], oxidative stress responses in liver and gill tissues [malondialdehyde (MDA) level, antioxidant enzyme activities: superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX), glutathione reductase (GR), glutathione-S-transferase (GST), glucose-6-phosphate dehydrogenase (G6PD)] and acetylcholinesterase (AChE) activity in brain tissue (as neurotoxic biomarker) were investigated. Additionally, behavioral differences were recorded by measuring swimming performance to support neurotoxic findings in all treatment groups. The LC5024 value of FDG-37 strain was determined through analysis as 1.0 × 108 CFU ml-1. Inhibition of enzyme activity, increase in the MDA level, as well as significant differences in hematological indices and swimming performance were determined in rainbow trout treated with B compared to control and other bacterial groups in gills. The potential for using group FD-48 and TV-17C bacterial strains as probiotics in aquaculture is more pertinent when considering the research findings and water quality parameters.

Authors: Al Solami Lafi
Published: January 2023

The concentration of heavy metals in marine fish is important for assessing the health risks associated with fish consumption. In this study, the concentration of metals such as copper, lead and manganese were analyzed in the muscle tissue of five coral reef-associated fish species collected from the central Red Sea, Saudi Arabia. The maximum copper content of 0.183 µg g-1 (ww) was detected in fish samples. Fish samples also showed maximum lead and manganese values of 0.030 and 0.064 µg g-1 (ww), respectively. The metal concentration in fish tissue samples did not vary significantly between the fish species. In conclusion, the results obtained indicate that the content of heavy metals in the coral reef-associated fishes is below the values determined by various agencies for seafood safety.
Effects of diet quantity on growth performance of juvenile sea cucumbers Holothuria scabra
Authors: Al-Harbi Mamdouh
Published: January 2023

Sea cucumbers are in high demand in the world market due to their nutritional and medicinal values. In this study, the growth performance of juvenile sea cucumbers Holothuria scabra fed with different proportions of two feeds was analyzed. Commercially available sea cucumber feed (feed-A) and formulated feed (feed-B) were used for the experiments. Animals fed with 2% feed-A showed a negative growth rate. Maximum growth was observed in animals fed with 8% feed-A and feed-B. While feed-A treated groups showed significant variation (P < 0.05) in growth performance between different percentages of diets, feed-B treated animals showed no such variation. Feed-B treated animals showed higher growth rates compared to feed-A treated sea cucumbers. Water quality parameters and anoxic conditions of the soil in culture tanks did not change due to the higher percentage of feeds. In conclusion, this study showed that diet percentage is an important factor for the optimum growth of sea cucumbers.
Assessment of 8-hydroxy-2-deoxyguanosine activity, apoptosis, acetylcholinesterase and antioxidant enzyme activity in Capoeta umbla brain exposed to chlorpyrifos
Authors: Kirici Mahinur
Published: January 2023

In this study, neurotoxic responses to exposure to chlorpyrifos (CPF) at different doses (55 and 110 µg l-1) and at different time intervals (24 and 96 h) were investigated in Siraz fish (Capoeta umbla) using 8-hydroxy 2-deoxyguanosine (8-OHdG) activity, caspase-3, acetylcholinesterase (AChE) and oxidative stress parameters [malondialdehyde (MDA), catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx) and glutathione reductase (GR)]. In this study, the LC50 value of CPF was determined for the first time for C. umbla and calculated as 440 µg l-1. In this study, 12.5% (55 µg l-1) and 25% (110 µg l-1) of the LC50 value were used. The obtained data indicate a significant increase in the MDA level and inhibition of antioxidant enzymes in the brain (p < 0.05). Considering DNA damage and the apoptotic process, no significant changes were found in 8-OHdG and caspase-3 activity at both doses exposed for 24 h, but a significant increase was detected in both markers at 96 hours compared to the control group (p < 0.05). In the case of AChE activity, which is one of the neurotoxic markers in the brain, while inhibition was determined only at the high concentration (110 µg l-1) at the end of 24 hours, a decrease in enzyme activity was observed at the end of 96 hours in both concentration groups. In the light of all these results, we can say that CPF showed inhibitory effects on enzyme activity and inducing effects on MDA, caspase-3 and 8-OHdG levels. Based on these results, it can be concluded that CPF contributes to oxidative stress in fish and may have neurotoxic effects.
Intercellular and extracellular amino acids of different bloom species in the Mediterranean Sea
Authors: Hosny Shimaa , El-Sheekh Mostafa , Labib Wagdy
Published: January 2023

The presented laboratory experiment was designed to characterize the quantity and compositional variation of algal extracellular amino acids (AAs) that may represent an alternative nutrient source in a natural environment. To resemble algal bloom scenarios, analyses were conducted in mono- and/or co-cultures of the bloom-forming species Skeletonema costatum, Scrippsiella trochoidea, Ulva fasciata, and Corallina officinalis during their active growth phase. The study revealed that S. costatum exhibited higher production of the dominant AAs than S. trochoidea. Alanine, lysine, and threonine acids are the dominant amino acids in S. costatum and S. trochoidea filtrates, which may play a role in mucus formation during mucosal phytoplankton blooms with negative ecological effects. On the other hand, aspartic, glutamine, alanine, and leucine acids are the dominant amino acids in macroalgae. In co-culture experiments, U. fasciata shows strong and rapid allelopathic activity against these two potentially harmful species. The AA production offers an advantage to species with the capacity to absorb them to form blooms. Thus, anthropogenic inorganic nutrient inputs may be less important for the development of algal blooms in coastal waters. A major difference that distinguishes this work from others is the use of specific multi-taxa cultures of phytoplankton and macroalgae. The study represents a new research effort in Alexandria waters.

Background/Aim: Several blood and serum-based parameters have been described as prognostic markers of clear cell renal cell carcinoma (ccRCC). But most of these markers have inconsistent results and are not used in routine clinical practice. Therefore, novel potential predictor biomarkers are needed for the management of ccRCC patients in clinical practice. Here, we investigate the predictive value of a novel marker, serum C-NLR score, for pathological characteristics and oncological outcomes of ccRCC.
Methods: A total of 162 RCC patients who underwent radical or partial nephrectomy between January 2015 and January 2021 were evaluated in a retrospective cohort study setting. The serum C-NLR score was compared according to the tumor histopathology-associated parameters. The predictive role of those parameters and C-NLR score on the oncological outcomes of ccRCC was also investigated.
Results: The median serum C-NLR scores exhibited statistically significant increases in ccRCC patients with pathological necrosis, lymphovascular invasion, and variant differentiation. Among histopathological characteristics, only tumor necrosis and variant differentiation were associated with overall survival (OS) and tumor grade with metastasis-free survival (MFS) (no metastasis detected in grade 1–2 tumors) in Kaplan Meier analyses. Serum C-NLR score was also associated with OS but not MFS. In the univariate analyses, tumor necrosis, variant differentiation, and C-NLR score were associated with OS of localized RCC patients who underwent nephrectomy (HR: 0.29; 95% CI: 0.08–1.01; P=0.04, HR: 6.01; 95% CI: 1.66–21.82; P=0.006 and, HR: 1.21; 95% CI: 0.20–5.16; P=0.04). However, in the multivariate analysis, only variant differentiation and C-NLR score were associated with OS (HR: 1.43; 95% CI: 0.82–2.98; P=0.03 and HR: 1.21; 95% CI: 0.20–5.16; P=0.04). Tumor grade was directly associated with MFS because grade 1–2 tumors did not exhibit any metastasis.
Conclusion: Serum C-NLR score was higher in worse histopathological entities. Moreover, it predicts the OS for patients with ccRCC as an independent factor.
DIGITAL MONOPOLIES: TASKS AND PROSPECTS OF LEGISLATIVE ANTIMONOPOLY REGULATION
Authors:   Russian State University for the Humanities, Timofeev Stanislav V.
Published: January 2023

The article deals with the issues of antimonopoly regulation of the activities of companies that are global digital giants. The activity of such companies is a kind of challenge for the antimonopoly authorities in all coun- tries of the world. Against the background of the pandemic, digital platforms are gaining special importance and are rapidly increasing their market share. During the period of active development of the digital economy, which is based on the information technology and innovative solutions, issues arise that are not typical for traditional markets for goods and services. There is a need to develop a new system of antitrust regulation that can protect competition, but at the same time takes into account the interests of companies operating in digital markets. In the digital economy, the main categories of antimonopoly regulation are fundamentally changing: it is more difficult to determine whet-her the price is monopoly; the points of application of the above regulation are shifting, as more and more transactions take place online and it is impossible to determine a specific responsible person; it becomes more complicated to form an evidence base in an antitrust case. Since the Internet overcomes both physical and legal boundaries, when building a regulatory system for the digital economy, it is necessary to take into account international experience and promote synchronization of the an- titrust laws of those countries where the largest players in digital markets are based. Participants in economic activity do not try to compete in some com- modity market, where are already many players, but generate new markets where they strive to become absolute monopolists. Today, “digital giants” have a large number of market power levers through the use and creation of new platforms, control and collection of data about users and product market par- ticipants, and the use of innovative methods of personalized marketing.

ECONOMIC EFFICIENCY OF EARLY EXTRACTION OF METHANE FROM COAL SEAMS IN MODERN CONDITIONS
Authors:   Российский университет дружбы народов, Мазурчук Т.М. , Черняев М.В. ,   Российский университет дружбы народов
Published: January 2023

One of the key problems of the coal industry in the modern world is the effective degassing and elimination of methane and other gaseous impurities from the developed seams. A high concentration of methane has a negative impact not only on the performance of the mine, but in case of significant excesses, it can lead to a stop in production. Coal mining companies are losing significant financial resources to restore the working capacity of mines and utilize gas impurities, meanwhile, more and more experts are turning to early degassing, which allows you to get rid of most of the natural gas even before the field is put into operation. The purpose of this work is to identify and analyze modern tools for early degassing of coal mines in Russia, taking into account sanctions restrictions on the import of foreign equipment, as well as economic instability in the international energy market. Utilization of methane with early degassing is possible not only by “standard” methods of emission into the atmosphere and flaring, but also by direct use both in the production itself in the generation of heat and electricity, and with subsequent transportation to the end consumer. This method increases economic efficiency and allows to provide power supply to the developed field without connection to the central networks. Also, early degassing has a positive effect on safety and reduces the risk of accidents involving people. The scientific basis of this study was Russian and foreign opinions and assessments of industry experts, statistical data of companies in the fuel and energy complex of Russia, information on patents and import substitution of foreign equipment in the coal industry, federal and regional regulatory databases.

Published: January 2023

This paper discusses the impact of macroeconomic factors on the activities of agricultural organizations. In particular, this paper examines the issues of forecasting the bankruptcy of agricultural organizations in modern conditions (for example, sanctions) of the Russian Federation. In the course of their activities, agricultural organizations in modern conditions may face the problem of bankruptcy. In order to avoid such a problem, agricultural organizations take into account many factors in their activities. To achieve results in this work, the following indicators were analyzed: the structure of exports of the Russian Federation for January 2021–January 2022; the monthly inflation rate in 2022; the population of the Russian Federation for 2018-2021 and June 2022; the number of agricultural organizations by value for 2021. The analysis showed that agricultural organizations need to take into account macroeconomic indicators in their activities, since such factors can lead to bankruptcy

Published: January 2023

El presente trabajo se enfoca en las prácticas de difusión científica que implementan académicos de Ciencias Sociales en la Universidad de Sonora (UNISON). El supuesto inicial que guía el estudio es que las políticas que evalúan la actividad científica han provocado cambios en las dinámicas de producción científica en Ciencias Sociales. A partir de esto, se plantea analizar las dinámicas de difusión científica de académicos de dicha institución. El estudio contempla a los académicos que participan en el Sistema Nacional de Investigadores (SNI), que figura como una política de carácter meritocrático en función del desempeño en actividades de investigación. Para ello, se realizó un cuestionario a un total de 40 profesores reconocidos por el sistema; se presenta un estudio de alcance descriptivo que analiza las tendencias y frecuencias en que los académicos utilizan determinadas estrategias de difusión científica, asimismo, se establecieron cruces entre los indicadores del instrumento y las características del perfil docente. Los principales resultados denotan una priorización a la producción de artículos científicos sobre el resto de los productos (capítulos de libro, ponencias, obras monográficas), se visibilizan publicaciones colocadas en medios internacionales y una tendencia a la publicación en redes científicas.

Para ello se desarrolla el método discursivo a lo largo del estudio. Finalmente, se alcanzan unos resultados que reflejan una evolución eficiente de los contenidos gamificados por la empresa informativa, pero que deben estar delimitados por objetivos y normas, de forma que se pueda obtener el interés del prosumer y que éste sea libre de elegir en qué comunidades y contenidos desea participar.
A COMPARISON OF “THE BLACK COAT” AND “THE OVERCOAT”: SIGNIFYING THE PRIMAL ROLE OF WOMEN WRITERS IN THE RUSSIAN SHORT STORY TRADITION
Authors: M. Padmavathy
Published: January 2023

This paper examines the paradigm shift in the genre of Russian horror short stories, and this tectonic shift is exemplified by a parallel reading of Nikolai Gogol’s “The Overcoat” and Ludmilla Petrushevskaya’s “The Black Coat”. The juxtaposition of these two stories exposes how male writers have always been placed on a pedestal in the Russian literary canon. In contrast, this paper highlights how the contributions of their female counterparts have been constantly sidelined, though both streams of works enriched the vast field of the Russian literary empire. Narratology theory is used to highlight the narrative techniques of both authors since it examines what narratives share and what makes them unique. This is illustrated by demonstrating how writers like Petrushevskya have dismantled the common notion that only male writers contribute to the technical aspects of a genre. Using the comparative methodology, this paper also traces the tradition of this genre and the holistic perspective towards the Russian women writers who outpoured their creative capacity, good enough to be recognised and appreciated. The conclusion of the paper discusses the way Ludmilla Petrushevskaya broke the former institution of short stories with a touch of psychic horror (female psyche) by going along with the characteristic features of Russian literature: the inner world of characters.
PALLAVA ELEMENTS IN SOUTH AND SOUTHEAST ASIAN ART – VISUAL APPRAISAL
Authors: Rajarajan R.K.K. , Rajarajan Jeyapriya

It is a known fact that contact between the Tamil country and Southeast Asia, including Śrī Laṅkā and China was a long-established tradition. References to the yavanas in Tamil Caṅkam literature and the notes supplied by Greek, Roman, and Egyptian classical authors would establish the fact that commercial intercourse between the east and west was an immemorial process 1, datable to at least a few centuries earlier than the Christian era 2. However, it was under the Pallavas and Cōḻas that the arts of the country made a daring intrusion into the distant lands 3. In this process of sharing artistic idioms from the subcontinent, the Āndhras of the Amarāvati School, the Guptas, and the Pālas of Beṅgal played a vital role. The Pallava link with the Malaya peninsula was blood-based because a collateral branch of the family is said to have ruled the distant land under Hiranyavarmaṉ whose son Nandivarmaṉ Pallavamalla (731-96 CE) became the ruler of Kāñci when there was no direct male heir to occupy the throne after the premature death of Parameśvaravarmaṉ II (Minakshi (1941), Subramaniam (1967) 80-94).
Metoda optymalnego projektowania sieci bazowej w monitoringu deformacji konstrukcji w elektrowni wodnej Song Hinh, Wietnam
Authors: PHAM Quoc Khanh
Published: January 2023

W artykule przedstawiono metodę optymalnego projektowania sieci bazowej w monitoringu przemieszczeń poziomych elektrowni wodnych na podstawie średniego poziomu rezydualnego zmierzonych wartości. Gdy funkcją docelową jest najsłabszy błąd pozycjonowania, uzyskany wynik po optymalizacji jest unikalnym planem, który nie zależy od projektantów i ich doświadczenia. Jest to więc pomocne dla jednostek produkcyjnych, ponieważ nie potrzebują one ekspertów do projektowania sieci. Eksperyment dla podstawowej sieci monitorowania deformacji w elektrowni wodnej Song Hinh pokazuje, że 44%, 50% i 60% początkowego pomiaru można zmniejszyć, gdy średni poziom pozostałości zostanie wybrany odpowiednio 0,5, 0,4 i 0,3. Najsłabszy błąd pozycji sieci po optymalizacji wynosi odpowiednio 2,4 mm, 2,5 mm i 2,6 mm, wszystkie są mniejsze niż wymagane ±3,6 mm. Metodę tę stosuje się głównie dla sieci kątów bocznych, które zostały zmierzone przez tachimetr, bez uwzględnienia optymalnej sieci projektowej w kierunku pierwszeństwa.

Zagłębie Górnicze Berbești, położone na obszarze Podkarpacia Getyckiego, jest częścią Zagłębia Centralnego (EC) Govora, posiada cztery odkrywki: Alunu, Olteț, Panga i West Berbești. Biorąc pod uwagę, że w Europie istnieje koncepcja rezygnacji z produkcji energii w oparciu o spalanie paliw kopalnych, zwłaszcza węgla, relatywnie krótko funkcjonować będą cztery odkrywki. Jednym z głównych problemów związanych z eksploatacją złóż węgla brunatnego jest stabilność gruntów na obszarze górniczym po zamknięciu eksploatacji. Badania przeprowadzono w taki sposób, aby uwzględnić w analizie stateczności czynniki i przyczyny naturalne, tenedencje terenów Podkarpacia Getyckiego do osuwisk, czynników i przyczyn antropogenicznych (wydobycie węgla brunatnego) oraz skutków oddziaływań towarzyszących. Analizy stateczności uwzględniały różne hipotezy związane z geometrią zboczy i wpływem czynników zewnętrznych. Przeprowadzono także analizę predykcyjną długoterminowej stabilności gruntów (zwłaszcza końcowych zboczy odkrywek) z uwzględnieniem zachowania się gruntów w czasie. Na podstawie uzyskanych wyników, po wykonaniu serii analiz statystycznych przeprowadzono analizę ryzyka, wykorzystując metodologię opracowaną przez część zespołu badawczego. Na wstępie należy zaznaczyć, że badania koncentrowały się na obszarach wydobywczych West Berbești i Panga, ponieważ wydobycie węgla brunatnego zostanie zakończone do końca 2022 roku. Biorąc jednak pod uwagę podobne warunki (geologia, morfologia, tektonika, strefy sejsmiczne, warunki pogodowe i klimatyczne, zastosowanych metod eksploatacji), zespół badawczy uważa, że znaczna część zawartych wniosków i rekomendacji w tym badaniu można uznać za ważne i dla pozostałych obszarów czynnych (odkrywki Alunu i Olteț). W tym kontekście opracowanie kończy się szeregiem wniosków dotyczących stabilności gruntów w zagłębiu górniczym Berbești (zachodnie Berbești i obwód
