New PMMA-InP/ZnS nanohybrid coatings for improving the performance of c-Si photovoltaic cells
Authors: Althumairi Nouf Ahmed , El-Bashir Samah 
Published: June 2024

Abstract
Luminescent down-shifting (LDS) nanohybrid films are considered a potential solution to match the absorption spectrum of photovoltaic (PV) cells with the AM1.5 solar spectrum. LDS films were prepared by spin-coating polymethyl methacrylate (PMMA) doped with indium phosphide/zinc sulfide (InP/ZnS) quantum dots (QDs). The effect of doping concentration was investigated using X-ray diffraction, thermogravimetric analysis, transmission, and fluorescence spectroscopy. The results demonstrated that all PMMA LDS nanohybrid films were amorphous and exhibited thermal and chemical stability for all the doping concentrations of QDs. The optimal doping concentration was 0.06 wt%, demonstrating a tunable emission of the highest fluorescence quantum yield of 92% and the lowest reabsorption effect. This film showed the maximum enhancement of the efficiency of c-Si PV cells by 24.28% due to the down-conversion of ultraviolet A (UVA) portion of solar spectrum (320–400 nm) to match the sensitivity of c-Si PV cells. The implications of these results are significant for advancing affordable and clean energy in alignment with important sustainable development goals.

Abstract
In this study, the polar root extract of Cyperus scariosus R.Br. was used for the biogenic synthesis of ZnO NPs. The results of this study show that ZnO NPs have a spherical structure with an average size of 85.4 nm. The synthesized catalysts were tested for their photocatalytic activity by degrading methyl orange and methylene blue under sunlight. Improved degradation efficiencies of 79.44% and 84.92% were achieved within 120 min. ZnO NPs exhibited strong antibacterial activity against both Gram-positive Listeria monocytogenes (18 mm) and Staphylococcus epidermidis (20 mm) and Gram-negative strains of Escherichia coli (16 mm) and Bordetella bronchiseptica (14 mm), as shown by the inhibition zones, which were comparable to the positive control (ceftriaxone) but larger than the plant root extract. ZnO NPs showed high antioxidant activity, as a ferric-reducing antioxidant power assay value of 66.29 µg (AAE µg·mL−1) and a DPPH value of 57.44 µg (AAE µg·mL−1) were obtained at a concentration of 500 µL, which was higher than those of the C. scariosus root extract. Quantification of the total phenolic and flavonoid content yielded values of 57.63 µg (GAE µg·mL−1) and 70.59 µg (QCE µg·mL−1), respectively. At a concentration of 500 μL (1 mg·mL−1), the tested nanoparticles (NPs) showed a greater anti-inflammatory effect (84.12%) compared to the root extract of C. scariosus (34.39%). Overall, our findings highlight the versatile properties of green synthesized ZnO NPs and demonstrate their potential for environmental remediation and antimicrobial formulations, as well as promising candidates for further investigation in biomedical fields such as drug delivery and therapy.

Published: June 2024

Abstract
A superhydrophobic copper coating was prepared by combining ionic liquid copper electrodeposition and a brief stearic acid modification process. After modification, the copper stearic acid was well formed and flower-like clusters were present on the surface of the superhydrophobic coating. Finally, the surface of the sample exhibits a good superhydrophobic performance with a contact angle of 158° and obvious self-cleaning behavior. The results of potentiodynamic polarization and electrochemical impedance measurements revealed that the presence of a superhydrophobic surface could improve the anti-corrosion property of the samples.
Kommunikationsdynamiken in „Klassenchats“
Authors: Wenzl Thomas 
Published: June 2024

Zusammenfassung
Der Beitrag geht von der Beobachtung aus, dass sich die Kommunikationsdynamiken in Klassenchats von Schüler*innen im Kindes- und im Jugendalter stark unterscheiden. Während die selbstorgansierten Klassenchats von Kindern regelmäßig in einer Flut von Nachrichten versinken, beruhigt sich diese Situation in den Klassenchats jugendlicher Schüler*innen deutlich. Für diese Differenz bietet der Beitrag eine „kommunikationsstrukturelle“ Deutung an, die nicht an den individuellen kommunikativen Voraussetzungen von Kindern und Jugendlichen ansetzt, sondern die die Peergroups von Kindern und Jugendlichen als kollektive Akteure betrachtet. Es wird die These entfaltet, dass die „Interaktionssysteme“ der Kindheit und der Jugend durch zwei zwar ähnliche, letztlich aber doch strukturell verschiedene Gleichheitsprinzipien gekennzeichnet sind, die es im Falle der Kindheit verunmöglichen, dass in größeren Gruppen sinnvoll „öffentlich“ kommuniziert werden kann, während sich in jugendlichen Peergroups allmählich die kollektive Fähigkeit, als Peergroup öffentlich miteinander zu kommunizieren, herausbildet.

Is It Possible to Increase Fertility in Latvia in the Near Future?
Authors: Komarova Vera , Sondore Anita , Čižo Edmunds , Kokarevica Anita 
Published: June 2024

This article aims to study the medium-term fertility trend in Latvia answering the following research question: is it possible to increase fertility in the near future, as planned in the “Population Reproduction Strategy FAMILY – LATVIA – 2030 (2050)”? The authors analyzed the total fertility rate (TFR) in Latvia for the period of 1970–2022 (53 years). This interdisciplinary (demography, mathematics, economics, sociology) study applies mathematical analysis for investigating socio-demographic trends, as well as the theory of economic cycles for identifying demographic cycles and their phases in Latvia and forecasting fertility rate in the near future. Furthermore, the analysis of data from comparative sociological surveys helped the authors to understand the main reason for the decline in fertility in Latvia. This reason is value changes in society, in which the child is no longer at the center of the value system of men and especially women in Latvia. In turn, short-term ups and downs in fertility are determined mainly by socio-economic and political factors. Based on the results of differentiating the function of the total fertility rate (TFR) it can be expected that the decline in fertility in Latvia will continue for several more years before the bottom of the next demographic cycle is reached and there will be an upturn in a linearly declining fertility trend. Although, the upcoming bottom will be lower than the previous one, i.e. below 1.22–1.25 children on average per woman and the next peak will most likely be below 1.74. Thus, the increase in TFR in Latvia to 1.77 by 2027, planned in the “Population Reproduction Strategy,” is considered by the authors of this study to be absolutely unattainable.
Oxcarbazepine: A usable alternative to carbamazepine in the treatment of trigeminal neuralgia- A pilot study and drug review
Authors: Singla Neetu 
Published: June 2024

Trigeminal neuralgia (TN) is an extremely debilitating neuropathic pain in which Carbamazepine (CBZ) is the preferred drug of choice in pharmacological management and surgical intervention to be considered only when drug therapy proves ineffective. However, it’s long-term use leads to refraction along with severe side effects has made to search for a suitable alternative to CBZ.Present study was conducted to evaluate the effectiveness of Oxcarbazepine (OXC) in those patients, who failed to get adequate relief despite taking CBZ for longer span. 15 patients including 12 males and 3 females (age group 30-65 years) mean age 53.3 years were prescribed OXC in subsequent doses of 300mg, 600mg, 900mg, maximum up to 2400mg and the pain relief was analysed using grading as No response, Moderate and Excellent response. Significant pain relief was observed as the dose was increased in the range of 1200-2400mg. Likert scale (5 points scale) for treatment satisfaction was used in which 2 patients marked as very satisfied, 11 patients were found to be satisfied, whereas only 2 marked as neither satisfied nor dissatisfied. : OXC, proves to be a useable alternative to CBZ in terms of being cost effective, better pain control and less side effects. A brief review of the drug OXC is also added.
Tapiserie króla Stanisława Augusta Poniatowskiego
Authors: Bender Agnieszka 
Published: June 2024

W artykule postawiono dwa pytania badawcze: po pierwsze, co wiemy na temat tapiserii w zbiorach ostatniego króla Polski, po drugie zaś, czy coś z tych zbiorów przetrwało.
Niestety w wiedzy na temat tapiserii ostatniego polskiego króla, ze względu na braki w materiale źródłowym oraz nieliczne przetrwałe obiekty, istnieje wiele luk trudnych do wypełnienia.
Reasumując, należy stwierdzić, że w przeciwieństwie do swoich królewskich poprzedników, Stanisław August, mimo kilku inicjatyw, z których większość nie doczekała się realizacji, nie wykazał zbyt dużego zainteresowania tapiseriami. Jego decyzje były i w tej kwestii chwiejne. Wymienić można kilka czynników, które — jak się wydaje — przyczyniły się do takiego stanu rzeczy. Po pierwsze, tapiserie nadal były bardzo drogie, a król, tak jak i cała Rzeczpospolita, stale borykał się z problemami finansowymi. Po drugie, Poniatowski, mimo pewnych nacisków ze strony Madame Geoffrin, wyczuł, że tapiserie jako pożądany od wieków element wystroju wnętrz królewskich rezydencji zaczęły stopniowo wychodzić z mody, wypierane przez styl „à la grecque”, do którego bardziej pasowały obicia ścienne z lekkich i tańszych jedwabnych adamaszków.
Zachowały się trzy obiekty związane z omawianym tematem:
— projekt tapiserii do Sypialni króla, Paryż, 1766 r., Warszawa — Zamek Królewski, Victor Louis,— tapiseria z portretem króla Jana III Sobieskiego, Polska, lata 60. XVIII w. (?), Muzeum Narodowe w Warszawie, warsztat François Glaize’a,— tapiseria ekran kominkowy z herbem króla Stanisława Augusta Poniatowskiego, Słonim, 1788 r., Muzeum Narodowe w Warszawie, warsztat Johana Carla Kletscha.
O zasadach ustroju terytorialnego Rzeczpospolitej Polskiej i konsekwencjach z nich wynikających słów kilka
Authors: Stec Mirosław 
Published: June 2024

Dotychczasowe doświadczenia, a przede wszystkim rezultaty, stawiające Polskę wśród krajów Unii Europejskiej najlepiej wykorzystujących możliwości rozwojowe uzyskane dzięki umiejętnemu połączeniu własnego, regionalnego potencjału aktywności ze strumieniem środków finansowych pochodzących z funduszy europejskich, a co znajduje potwierdzenie w jednoznacznie pozytywnych ocenach działań samorządu wynikających z badań opinii społecznej, pozwalają stwierdzić, że trafnie sformułowano w Konstytucji i ustawach wprowadzających reformę terytorialną w 1998 r. założenia aksjologiczne i ideowe, a następnie, z nich wynikające, instrumentarium ustrojowoprawne, pozwalające uruchomić i uaktywnić maksimum możliwości tkwiących w społecznościach regionalnych i lokalnych. Dlatego ze słowami zdecydowanej krytyki winna się spotkać aktywność legislacyjna tak Sejmu, jak i Rządu RP, w ostatnich kilku latach, której rezultatem jest wyraźne łamanie zasady decentralizacji i wprowadzanie rozwiązań centralistycznych, wyrażające się, w szczególności, w – po pierwsze – odbieraniu samorządowi, zwłaszcza wojewódzkiemu, do niego należących z natury swej zadań (choćby w zakresie ochrony środowiska), po drugie – ograniczaniu samodzielności finansowej poprzez zmniejszanie dochodów własnych (zwłaszcza podatkowych) i wprowadzaniu w to miejsce uznaniowego finansowania o charakterze dotacyjnym z różnego typu funduszy rządowych, po trzecie – przyznawaniu organom administracji rządowej, nieznajdujących ustrojowego uzasadnienia, uprawnień władczych wobec organów samorządowych (np. w sferze oświaty czy ochrony zdrowia). Dalsze prowadzenie takiej polityki oznacza jednoznaczny powrót do modelu ustroju terytorialnego właściwego Polskiej Rzeczpospolitej Ludowej, opartego na centralistycznych strukturach rad narodowych.
Fibril-forming motif of non-expanded ataxin-3 revealed by scanning proline mutagenesis
Authors: Meng Sheng-Rong , Ma Chao , Chen Jie , Wang Li-Qiang , Hu Hong-Yu , Liang Yi 
Published: June 2024

Aims: The misfolding of ataxin-3 in neurons is the hallmark of a neurodegenerative disease, spinocerebellar ataxia type 3 (SCA3), also known as Machado-Joseph disease (MJD). Ataxin-3 consists of a N-terminal Josephin domain and a C-terminal polyglutamine (polyQ) tract. The length of the polyQ tract is positively correlated with the disease. The aggregation of ataxin-3 in vitro is a two-step process, with the first step involving the aggregation of the Josephin domain and the second step involving an expanded polyQ tract. However, the fibril-forming motif of the Josephin domain is not well understood.
Methods: In this study, we employed 3D profile algorithm and scanning proline mutagenesis to identify the fibril-forming motif of non-expanded ataxin-3.
Results: By using thioflavin T fluorescence kinetics, sarkosyl-insoluble SDS-PAGE, transmission electron microscopy (TEM), and Fourier transform infrared spectroscopy (FTIR), we identified the fibril-forming motif of the Josephin domain of non-expanded ataxin-3 as 79VISNAL84.
Conclusions: We demonstrated that the proline mutation in the fibril-forming motif of the Josephin domain could inhibit the aggregation of expanded ataxin-3, which shows some therapeutic promise.
Interrelatedness of the naming of children in the South African cultural context
Authors: Madima Thizwilondi 
Published: June 2024

The study seeks to explore the interrelatedness around the naming of children in the traditional societies of Southern Africa. Traditionally, among the Vhavenda, Vatsonga, Bapedi, Xhosa, Zulu, Swati and other various African cultures in Southern Africa, it was the duty of the grandparents to name their grandchildren. The naming was largely influenced by the events which occurred in the family. The study was conducted first to establish the interrelatedness in the naming of children among the multicultural context of traditional societies of Southern Africa, secondly to determine whether the naming has implications to the behaviour and character of the child while they grow. Senior citizens who are knowledgeable were interviewed on what were considered in the naming process and what are the cultural values that are attached to this process. Data was collected using semi structured interviews and analysed thematically. Afrocentric theory was utilised as the basis for the research findings. The research findings were of paramount importance around some of the individual names among different cultures and the implications of the behaviour of a child when he grows. The paper recommends the reimagining of the spirituality around some individuals names and the naming process, the revival of the traditional naming process is meant for cultural heritage preservation.
Reducing prejudice against learners with disabilities in inclusive settings through the Afrocentric model of inclusion
Authors: Mokobane Sonti 
Published: June 2024

Attitudinal barriers and discriminatory practices continue to prevent the full participation of learners with disabilities in developmental learning contexts. Although disability has been on the psychological agenda for some time, there is limited empirical evidence on adopting African models to buffer prejudices. This paper addresses this critical gap by examining the experiences of disabled children subjected to prejudices in inclusive settings and the adaptation of the Afrocentric model to buffer those behaviors. The paper was guided by Allport's Social Reflection Theory, which explains why some groups may be targets of prejudice. The exploratory qualitative case study was undertaken in 4 inclusive schools in Gauteng province. Participants were 20 educators and 40 disabled learners in inclusive schools. Purposive sampling was used to choose participants in the study. Data was collected through semi-structured interviews with educators, and the researcher observed the engagement of the educators and 40 disabled learners. Data collected were analyzed through qualitative thematic data analysis. From the themes that emerged in the findings, the following themes were discussed: advancing the truth in our praxis, fairness, harmony, and humanness. The paper, therefore, recommends that educators apply the practice of including the emerged themes in their learning content for improved grades and low dropout rates.

One of Indonesia's current development sectors is climate change control. Program Kampung Iklim was created, so that communities at the site level can carry out adaptation, mitigation, and institutional actions & sustainable support. Palasari hamlet is a ProKlim hamlet, but has low participation from the female population, so that achieving program sustainability is slightly hampered. The purpose of this study was to determine women's participation in the Program Kampung Iklim. The method used in this research is a case study with data collection through interviews, observation, and documentation. The results showed that women's participation went through 4 stages, (1) women's participation in ProKlim planning, including response participation such as asking questions in socialization activities and participation of tools and materials. (2) Women's participation in the implementation of ProKlim, there is participation of support, there is also participation of expertise and labor. (3) Women's participation in the utilization of ProKlim results, there is an increase in knowledge because it is reflected in the skills in utilizing yard land to improve food security. (4) Women's participation in the evaluation of ProKlim, namely by giving opinions/responses when the activities/programs have been implemented. ProKlim is a series of processes using the principle of empowerment, with the aim of reducing greenhouse gas emissions to create prosperity.
