Self-Esteem, Academic Engagement and Fatigue among Undergraduates: Assessing the Role of School Support
Authors: Olatunbosun Stella Oluwakemi , Pillay Jace
Published: November 2024

The academic success or failure of students is influenced by various factors, including psychological elements like self-esteem, academic engagement, and academic fatigue. There is anecdotal evidence to suggest that the support from schools plays a crucial role in shaping these psychological aspects in students. The proposed study examined this contention through quantitative survey research using 314 university students selected using purposive and simple random sampling techniques from two Nigerian public universities. Google Forms were used to survey the sampled respondents' views on the role of school support in self-esteem, academic engagement, and academic fatigue using the "School Support and Undergraduates' Self-esteem, Academic Engagement, and Fatigue Questionnaire." The data obtained for the study were analysed using descriptive statistics (frequency counts and percentages), correlation, and regression analysis at a 5% significance level. The results indicate that high school support for undergraduates positively predicts their self-esteem, academic engagement, and academic fatigue. These findings underscore the effectiveness of diverse school support mechanisms, particularly within the university context, in fostering a positive and productive academic environment for undergraduates. Such support enhances students' self-esteem and academic engagement while significantly reducing academic fatigue. Consequently, expanding the availability and accessibility of university support services would promote self-esteem and academic engagement while alleviating levels of fatigue among undergraduates. This study holds practical importance for the Nigerian university system and other institutions across Sub-Saharan Africa, highlighting the critical role of school support in improving students’ academic outcomes. Recommendations are provided.

Published: November 2024

Propellant is a core fuel in defense and aerospace applications. However, conventional hydrazine fuel is highly volatile, toxic, and carcinogenic, resulting in huge threats to the human body and environment. N,N-dimethylethanamine (DMAZ) is a green, high-energy fuel with a low freezing point, high density, high specific impulse, and high combustion rate, and it is a promising substitute of conventional hydrazine fuel. Nevertheless, the industrial application of DMAZ is limited by long ignition delay. In this study, the mechanism of ignition of DMAZ was explored by summarizing current methods to reduce the ignition delay of DMAZ, including the addition of catalyst, fuel formulation, and tuning molecular structure. This study provides references for applications of amine azide.
Study on Phase Evolution of Calcium Silicate Hydrate (C-S-H) During Solidification of Cr(VI) under Hydrothermal Conditions
Authors: ZHAO Zhiguang , QU Xiaoling , LI Zhanming , TIAN Changan , LI Zaibo
Published: November 2024

In this paper, calcium silicate hydrate (C-S-H) was synthesized by hydrothermal method using CaO and quartz sand as raw materials. The solidification effect of Cr(Ⅵ) in C-S-H was studied using XRD, FTIR, and SEM. The leaching amount of Cr(Ⅵ) after solidification was determined by anatomic absorption spectrometer to analyze and calculate the solidification rate of Cr(Ⅵ). Results show that appropriately increasing the reaction temperature and prolonging the reaction time can help improve the crystallinity of C-S-H. A small Cr(Ⅵ) dosage of Cr/Si < 0.05 is beneficial for the crystallization of C-S-H, but when Cr/Si > 1.0, Cr(Ⅵ) ions inhibit the formation of C-S-H. When Cr/Si <0.15, the solidification efficiency of C-S-H on Cr(Ⅵ) decreases with increasing Cr(Ⅵ) content; The C-S-H with Ca/Si = 1 has the best solidification efficiency for Cr(Ⅵ).

Published: November 2024

Resistance spot welding (RSW) is a widely employed technique for joining aluminum and copper alloys, valued for its efficiency and effectiveness. However, the mechanical properties of the resulting welds, particularly their tensile strength and resistance to deformation, often fall short of industrial demands. This study explores the incorporation of Silicon Carbide nanoparticles (SiC NPs) as a method to enhance the mechanical performance of RSW joints in aluminum and copper alloys. Experimental results demonstrate that the addition of SiC NPs significantly improves tensile strength, with gains primarily attributed to grain refinement and the formation of dispersion-strengthening mechanisms. Advanced characterization techniques, including Field Emission Scanning Electron Microscopy (FESEM) and EDS analysis, provide detailed insights into the morphological and structural transformations within the weld zones. These findings underscore the potential of SiC NPs to not only enhance the strength and durability of RSW joints but also to advance the overall quality and reliability of welding processes in aluminum and copper alloys. This research opens new avenues for the application of nanoparticle reinforcement in industrial welding, offering a pathway to achieve superior joint performance.

Auslöser können frühkindliche Stresserfahrungen (Early Life Stress) sein, die prä-, peri- und postnatal auf das kindliche Gehirn wirken. Der vorliegende Band betrachtet Early Life Stress aus einer biopsychosozialen Sichtweise. Was bedeutet Stress? Inwiefern nimmt er Einfluss auf neuroplastische Vorgänge im kindlichen Gehirn? Und wie können präventiv Maßnahmen getroffen werden, um Early Life Stress entgegenzuwirken? Die Autorin zeigt eindrucksvoll, dass stressreiche Umwelterfahrungen im frühen Kindesalter die Entwicklung des Gehirns sowie die spätere Lernfähigkeit beeinflussen können. Sie erstellt ein umfassendes Programm, das durch förderliche Umweltfaktoren im familiären sowie (vor-)schulischen Setting positive Lernerfahrungen ermöglicht und Early Life Stress aktiv entgegenwirkt. Ein Präventionsprogramm, das nicht nur für sinkende Gesundheitskosten sorgen kann, sondern vor allem für eine Steigerung der Lebensqualität von Kindern und Eltern.

Published: November 2024

Background: With the widespread use of electronic devices, visual fatigue has become a prevalent issue in modern society. Non-pharmacological interventions, such as facial massage and exercise, have been proposed as effective methods for alleviating visual fatigue. However, the specific effects and mechanisms behind these interventions require further exploration. Objectives: This systematic review aims to evaluate the effectiveness of facial massage and exercise in reducing visual fatigue and to explore the underlying mechanisms of these interventions. Methods: A comprehensive search was conducted across multiple databases, including PubMed, Web of Science, Scopus, and the Cochrane Library. Randomized controlled trials and crossover experiments were included for both quantitative and qualitative analyses of relevant studies. Results: The findings suggest that both facial massage and exercise can reduce visual fatigue. Facial massage alleviates eye strain by stimulating the parasympathetic nervous system, reducing stress and anxiety, relaxing muscles, and improving blood circulation. Exercise alleviates visual fatigue through two mechanisms: (1) enhancing overall blood circulation, reducing stress, improving sleep quality, and overall health; (2) directly exercising eye muscles through eye yoga, which helps relieve visual fatigue. Conclusions: Preliminary research indicates that facial massage, full-body exercise, and eye yoga hold potential as non-pharmacological interventions for visual fatigue. Eye yoga has experimental support for its ability to strengthen eye muscles and improve focus. Massage stimulates parasympathetic activity and boosts blood circulation, while full-body exercise enhances systemic circulation to relieve eye fatigue. Future research should focus on investigating the mechanisms of these interventions in more detail and comparing the effects of various types, intensities, and durations to provide more precise clinical recommendations.

Penelitian ini bertujuan untuk mengetahui pengaruh penyemprotan larutan jeruk nipis dan larutan gula pada dosis 15% dan 20% terhadap lama pipping, daya tetas dan mortalitas telur itik pada mesin tetas. Penelitian ini menggunakan rancangan acak lengkap (RAL) pola faktorial 2x2 dengan jenis larutan penyemprot (P1 : jeruk nipis dan P2 : gula) sebagai faktor pertama dan dosis larutan (D1 :15% dan D2 : 20%) sebagai faktor kedua, serta perlakuan kontrol (P0D0). Masing-masing perlakuan diulang sebanyak 3 kali dan setiap ulangan yang dilakukan terdiri dari 3 butir telur itik. Hasil penelitian menunjukan bahwa penyemprotan larutan jeruk nipis mampu mempercepat lama piping pipping hingga 6,20 - 8,16 jam, meningkatkan daya tetas hingga 33,33% dan menurunkan mortalitas hingga 66,67% dibandingkan perlakuan kontrol, sedangkan penyemprotan menggunakan larutan gula memperlambat lama pipping hingga 4,30 â€“ 7,27 jam, menurunkan daya tetas hingga 55,56% dan meningkatkan mortalitas hingga 44,44% dibanding perlakuan kontrol.
Pengaruh Pemberian Pupuk Bokashi Feses Ayam Dan Daun Kirinyuh Dengan Level Yang Berbeda (0, 15, 30 Dan 45 Ton/Ha) Terhadap Pertambahan Panjang Daun, Produksi Berat Segar, Dan Komposisi Fraksi Serat Pada Pertumbuhan Ketiga Rumput Odot

This research aims to see the increase in leaf length and fresh weight production as well as the fiber fraction content in odot grass plants given chicken feces bokashi fertilizer and kirinyuh leaves in each bed plot at different levels. The research was conducted in Kuta Village, Kanatang District, East Sumba Regency. The main research material used was odot grass cuttings, with soil beds and using chicken feces bokashi fertilizer. The experimental design used was a Completely Randomized Design (CRD) with 4 treatments and 4 replications where each replication consisted of 9 odot grass seedlings/cuttings so that there were a total of 144 experimental units. Treatment P0: no fertilizer (control); P1: fertilizer application 15 tons/ha; P2: fertilizer application 30 tons/ha; P3: fertilizer application 45 tons/ha. The results of the study showed that the application of chicken feces bokashi and kirinyuh fertilizer at doses of 0, 15, 30 and 45 tons/ha in the second week had an effect on leaf length growth, but in the fourth to the eighth week it had no real effect because it was most likely The effect is reduced availability of nutrients in the soil. The fresh weight production results of odot grass had a significant effect on the fertilizer treatment compared to without fertilizer where P3 (923.75g) gave the best results compared to all treatments. Meanwhile, the analysis of fiber content shows that the value for each fiber fraction is good with an average NDF (76.274%); ADF (43,915); Cellulose (30,696); Lignin (3,419); Hemicellulose (32,359); and Silica (0.578). It can be concluded that by administering chicken feces bokashi fertilizer at a level of 45 tons/ha, it is still able to provide the best results for growth and third harvest of odot grass plants.

This research was conducted in Kuta Village, Kanatang District, East Sumba Regency. The tools used include drum plates, thermometers, measuring tape, tarpaulin, books, pens, plastic samples, scales and ovens. The materials used are odot grass cuttings, chicken feces bokashi fertilizer and kirinyuh leaves. The experimental design used in this research was a Completely Randomized Design (CRD) consisting of 4 treatments and 4 replications and each replication consisted of 9 odot grass cuttings, so there were 144 experimental units. This research is a follow-up research on the growth of three odorata grasses (Pennisetum purpureum Cv. Mott) by applying chicken feces bokashi fertilizer and kirinyuh leaves (Chromolaena odorata) at levels of 0, 7; 5, 15 and 22.5 tonnes/ha. The results of this research show that there is a significant difference in the leaf length variable at 2 weeks of age but not a significant difference at 4-8 weeks of age between odot plants given or without bokashi fertilizer. The research results also showed that there were significant differences in the fresh weight production variable between fertilizer treatment (P1: 731 grams; P2: 732 grams; P3: 736 grams) compared to no fertilizer treatment (P0: 656 grams). The fiber fraction test results showed good results where the average cellulose content was 30.26%; hemicellulose 31.39%; and lignin content is only 3.5%. It was concluded that applying fertilizer up to the level of 7.5 tons/ha was still able to provide good results for odot grass plants in the third growth and harvest.
