Challenges in Understanding the Mole Concept Among Level 200 Students in Science Colleges of Education in Ghana

This study investigates challenges in understanding the mole concept among pre-service teachers in Ghanaian Colleges of Education. Chemistry education is fundamental for fields such as medicine and engineering, yet students often face difficulties due to inadequate foundational knowledge and ineffective teaching methods. The mole concept is crucial for grasping various chemical phenomena, but its complexity frequently results in significant learning challenges. This study employs a mixed-method explanatory design, combining quantitative diagnostic tests and qualitative interviews with 1,211 pre-service teachers from six selected colleges. The study identifies key challenges in learning the mole concept, including difficulties in translating word problems into equations, determining mole ratios, deriving empirical and molecular formulae, and understanding the relationship between stoichiometric coefficients and moles. The analysis categorizes these challenges into comprehension, transformation, process skills, and encoding errors, with process skills and transformation challenges being the most prevalent. Findings reveal that many students struggle to solve problems without formulae, highlighting a lack of conceptual understanding. Interviews with pre-service teachers confirm quantitative data, indicating that students often rely on rote memorization rather than conceptual grasp. The study concludes that improvements in teaching methods are needed, emphasizing the importance of understanding over memorization and recommending small group collaborative learning. Contributions include filling empirical gaps in the literature regarding pre-service teachers’ challenges and suggesting practical recommendations for enhancing chemistry education.

The Effects of Post-Earthquake Trauma Levels of Nursing Students on their Academic Motivation and Career Decisions.

This study was carried out to determine the effects of post-earthquake trauma levels of nursing students on their academic motivation and career decisions. The sample of this descriptive study consisted of 228 students studying at Gaziantep Islamic Science and Technology University, Department of Nursing. The data were collected using an online questionnaire created by the researchers. This online questionnaire form consists of seven questions about socio-demographic characteristics, and it also includes the Determination of Post-Earthquake Trauma Levels Scale, Academic Motivation Scale, and Career Decision Scale. SPSS 23.0 package program was used for the analysis of the data, and P < 0.05 was accepted for the level of significance. It was determined that the post-earthquake trauma level of the students was above the moderate level (63.49 ± 17.29) and that the extrinsic motivation-identified regulation, extrinsic motivation-external motivation, and intrinsic-knowledge levels were more affected by the earthquake (P < 0.05). In addition, it was determined that the mean Career Decision Scale score of the students (74.20 ± 17.35) was below the average. It was determined that post-earthquake trauma level had positive effects on intrinsic motivation-stimulation, extrinsic motivation, and amotivation, but had no effect on career decision.

Functional metal-organic frameworks derived electrode materials for electrochemical energy storage: a review.

Pristine metal-organic frameworks (MOFs) are built through self-assembly of electron rich organic linkers and electron deficient metal nodes via coordinate bond. Due to the unique properties of MOFs like highly tunable frameworks, huge specific surface areas, flexible chemical composition, flexible structures and a large volume of pores, they are being used to design the electrode materials for electrochemical energy storage devices. As per the literature, MOFs (including manganese, nickel, copper, and cobalt-based zeolitic imidazolate frameworks (ZIFs), University of Oslo (UiO) MOFs, Hong Kong University of Science and Technology (HKUST) MOFs and isoreticular MOFs (IRMOFs)) have attracted much attention in the field of supercapacitors (SCs)/batteries. According to their dimensionality such as 1D, 2D and 3D, pristine MOFs are mainly used as SC materials. Highly porous materials and their composites are capable for intercalation of metal ions (Na+/Li+). Moreover, the supramolecular features (π⋯π, C-H⋯π, hydrogen bond interactions) of redox stable MOFs provide better insight for electrochemical stability. So, this review provides an in-depth analysis of pure MOFs and MOF derived composites (MOF composites and MOF derived porous carbon) as electrode materials and also discusses their metal ion charge storage mechanism. Finally, we provide our perspectives on the current issues and future opportunities for supercapacitor materials.

With the ageing population, it is important that the elderly require the help and assistance they may need to carry out their daily lives and have the best quality of life possible. Taiwan is an example of a country where the ageing population continues to grow, to the extent that Taiwan is an Aged Society. Distinguished Professor Dengchuan Cai is Director of the R&amp;D Centre of Product Innovation and Assistive Technology, which is based within the Department of Industrial Design at the National Yunlin University of Science and Technology in Taiwan. He is passionate about R&amp;D and its crucial role is pushing forward scientific enquiry. He and his team are working to develop tools and devices that can benefit the lives of the elderly. Cai is harnessing his background in human factors engineering and industrial design to apply knowledge in skills in functionality, useability and appearance to advance his investigations and wider R&amp;D. One of many foci for the Centre is competitiveness and product value enhancement in the hand tools and aids industry, which is particularly beneficial for the elderly. A key invention for the Centre has been pillows with different heights for when a person is lying on their front or lying on their side to help maintain the natural posture of the spine when sleeping and thereby improve sleep quality. Another key technology is a dementia prevention bicycle built on the concept of reverse pedalling.

Research examining microcirculatory dynamics in diseases that cause oedema using skin blood flow and skin reperfusion pressure

Oedema is a build-up of fluid in the tissues in the body. It can develop due to diseases including heart failure and kidney disease. It usually occurs in the limbs, where it can cause discomfort, joint stiffness or pain. However, fluid can also accumulate in the brain, which is called cerebral oedema or in the blood vessels serving the lungs, called pulmonary oedema. A type of oedema called pitting oedema is more prevalent than the other type, non-pitting oedema. In order to treat the condition, the underlying cause must be resolved. Treatment can involve diuretics to help the release of fluids, positioning to encourage draining or compression to force fluids away. Researchers at the Faculty of Rehabilitation at Reiwa Health Sciences University led by Dr Haruki Kogo are examining the microcirculatory dynamics of diseases that cause oedema using skin blood flow and skin reperfusion pressure. They have developed a device that can diagnose oedema and confirmed the reproducibility and validity of the device. They have registered the trademark and plan to commercialise the device for use in clinical and research settings. The device is able to measure the depth of the surface imprint in pitting oedema patients, simplifying the evaluation of pitting oedema, which will be extremely useful in clinical settings. The researchers tested the device across two hospitals, comparing the results with results obtained from the popular circumference measurement method and ultrasound imaging measurement. The team found that there was a strong correlation between measurements from the device and the tissue thickness measurement derived from the ultrasound. This confirmed that the device is a reliable gauge for the measurement of oedema.

Development and validation of a self-esteem improvement program for family caregivers with dementia ‐ Utilizing ICT

The sense of caregiving burden can be significant among family caring for people with dementia and can impact mental health. Research to find ways to alleviate this burden is extremely important. Dr Yoshihiro Saito, Faculty of Nursing, Reiwa Health Sciences University, Japan, is leading a team working to develop and validate a self-esteem improvement programme designed for family caregivers of those with dementia. The project was inspired by Saito experiencing firsthand the stresses placed on family carers of people with dementia. The goal of the programme is to reduce the self-blame of dementia family caregivers and is informed by Saito’s expertise in cognitive behavioural therapy. A key part of the programme is self-compassion in order to help caregivers realise their worth. Ultimately, the aim is that, through the programme, caregivers can be kinder to themselves and realise the value and significance of their efforts. Alongside heading up this project, Saito is a supervisor for the Cognitive Behavioural Therapy Training Programme of the Ministry of Health, Labour and Welfare in Japan, focusing on popularising cognitive behavioural therapy and training the next generation. In this role, he listens to and reviews recordings of cognitive behavioural therapy sessions, providing practical advice. In the context of Japan’s ageing population, there will be an increase in people with dementia and family caregivers. Therefore, Saitoâ–™s work will be hugely beneficial in assisting those with dementia, caregivers and society.

Beyond the first week: sustaining the feeling of social inclusion and sense of belonging for students

ABSTRACT Purpose Promoting inclusive student communities and a sense of belonging is essential for university students’ well-being and mental health. Our aim in this study was to explore how universities can enhance student well-being by facilitating interactions that contribute to a sense of belonging within the university environment. Methods Through thematic analysis of 309 written narratives collected from students at the Norwegian University of Science and Technology (NTNU), we explored significant events related to their studies, social lives, or personal experiences. Results Introduction Week is important for students’ well-being, providing a key opportunity to form initial social connections and foster a sense of belonging. However, its impact is inconsistent, and building lasting relationships requires continued effort throughout the academic journey. Recognizing and addressing potential challenges when expectations are unmet is essential for enhancing student belonging. Conclusions Our findings suggest that while Introduction Week plays an essential role in breaking social barriers and ensuring immediate social inclusion, the greatest challenge lies in establishing structures that facilitate belonging and relationships throughout the entire period of studies. Recognizing the diverse needs of students, universities should offer a variety of platforms for engagement and connection to enhance student well-being.

Comparative Evaluation of Antibiotic Therapies for Subclinical Staphylococcal Mastitis in Goats

Subclinical mastitis (SCM) is characterized by inflammation of the udder without visible signs of inflammation in the animal, udder and milk and hence could be diagnosed by laboratory examination only. Effective treatment of SCM in goats is crucial for maintaining quality milk production. This study was conducted at the Department of Veterinary Medicine, College of Veterinary Science and Animal Husbandry, Nanaji Deshmukh Veterinary Science University, Jabalpur (M.P.), India. A total of 236 lactating goats irrespective of age, breed, parity and stage of lactation, from both organized and unorganized sectors in and around Jabalpur, were screened over a period of six month. Based on modified California mastitis test scores, 83 goats tested positive for subclinical mastitis resulting in an overall occurrence of 35.17% (83/236). A total of 48 milk samples that tested positive for modified California mastitis test were further analyzed for bacterial isolation and identification. Among them, 34 (70.83%) samples were positive for only Staphylococcus spp., while 12 (25%) samples exhibited mixed infection with Staphylococcus spp. and Gram-positive bacilli. Then, 18 goats, positive for subclinical Staphylococcal mastitis were divided into three groups i.e. G1, G2 and G3 with six goats in each group for therapeutic study and six apparently healthy goats were taken as healthy control group (G4). G1 Goats were treated with Inj. Enrofloxacin LA @ 7.5 mg/kg b. wt. I/M single dose; G2 with Inj. Ceftizoxime @ 10 mg/kg b. wt. I/V single dose and G3 with Inj. Oxytetracycline LA @ 20 mg/kg b. wt. I/M single dose. The responses of therapeutic assessment were evaluated on the basis of somatic cell count and modified California mastitis test score. The most effective response for subclinical Staphylococcal mastitis in goats was observed with Ceftizoxime followed by Enrofloxacin LA and the least with Oxytetracycline LA.

Therapeutic Efficacy of Eucalyptus Oil as Teat Dip in Subclinical Mastitis in Goats

Mastitis, an inflammation of the parenchyma of mammary gland, results in alterations to the chemical and physical composition of milk due to a variety of infectious and non-infectious causes. The present work was conducted in the Department of Veterinary Medicine, College of Veterinary Science and Animal Husbandry, Nanaji Deshmukh Veterinary Science University, Jabalpur, Madhya Pradesh (M.P.). A total of 256 lactating goats irrespective of age, breed, parity and stage of lactation belonging to both organized and unorganized sectors at Jabalpur were screened from “February 2024 to July 2024”. On the basis of modified California mastitis test (MCMT) score, out of 256 lactating goats, 98 goats were found positive for subclinical mastitis with overall occurrence as 38.28% on animal basis and 33.33% on udder halves basis. Therapeutic study on 24 milk samples positive for subclinical mastitis by MCMT was conducted and categorized into four treatment groups (G1, G2, G3 and G4), each group comprised of 6 goats. Six apparently healthy goats were selected as healthy control group (G5). Two different teat dips viz. Eucalyptus oil 98% + DMSO 2% BID for 14 days in groups G1 and G3 and 5% Povidone iodine BID for 14 days in groups G2 and G4 were used as teat dips, respectively. Moreover, goats of groups G3 and G4 were commonly treated with parenteral antibiotic amoxicillin sulbactam @10 mg/kg b.wt. I/M OD for 3 days. Significantly higher values of somatic cell count, standard plate count, pH, freezing point and significantly lower value of lactose were observed in subclinical mastitis affected goats. The mean density and mean water percentage values varied within normal physiological range. On the basis of restoration of milk parameters and standard plate count, the most effective therapy was elicited by Eucalyptus oil 98%+ DMSO 2% as teat dip in combination with antibiotic amoxicillin sulbactam (G3).

Conclusions: While undergraduate health science students generally demonstrate an acceptable level of knowledge and positive attitudes toward HBV infection prevention, there remain significant gaps in practice, particularly regarding vaccination uptake and adherence to standard precautions.

Exploring How Female Scientists are Uplifted in Research Networks in STEM Fields in Public Universities in Uganda

Participation in research networks is inevitable for the female scientists in the Science Technology Engineering and Mathematics (STEM) fields because they provide a platform for collaborative activities. New research communities of women are created to support each other through mentoring, advancing shared research interests, co-organizing conferences with men, participating in the editorial and the publications. It was on this basis that this study explored how female scientists were uplifted by research networks in STEM fields in public universities in Uganda. This study was anchored on the existential phenomenology by Martin Heidegger in the interpretive world view. Eight female scientists in research networks in STEM fields in public universities in Uganda were interviewed and they were selected from the hard applied and hard pure disciplines as classified in Becher and Biglan’s typology of academic disciplines. Using thematic analysis, two themes such as research collaboration activities and capacity development emerged in this study. This qualitative study set out to explore how female scientists were uplifted in research networks in public universities in Uganda.The public universities included Makerere University, Mbarara University of Science and Technology, Gulu University and Busitema University. Both semi-structured interviews and document check data generation strategies were used in this study. In semi-structured interviews, a sample comprising eight female academics with not less than five years in research networks in public universities were selected, while documents such as the annual reports and strategic plans were used. This study concludes that research networks are uplifting the female scientists in STEM fields in public universities in Uganda because they were internationally exposed, networked, funded, research skills were strengthened, and progressed in career. This study concludes that it was important for female scientists to access physical and human resource in their research networks as this increased their research performance and outputs in STEM fields in public universities in Uganda. This study therefore recommends that, to uplift female scientists in research networks in STEM fields in public universities in Uganda, female scientists in the research networks and senior colleagues should act as ambassadors and mentors to young female scientists in STEM fields

Association of STAT1 gene with milk fat and protein yield in Holstein Friesian crossbred cattle maintained in the sub-tropical climate of India.

Signal transducers and activators of transcription (STAT) genes are involved in signal mediation of various hormones and cytokines. STAT1 located on chromosome number 2 is involved in mammary gland development and is associated with milk composition traits in bovines. This study aimed to find any relationship and impact of STAT1/BspHI gene with milk fat and protein yields in a herd of Holstein Friesian (HF) crossbred cattle of sub-tropical climate of Northern India. Milk composition data of 535 adult HF crossbred cows for a period of 12 years was collected from the records maintained at Livestock Farm, Guru Angad Dev Veterinary and Animal Sciences University. First lactation data of 222 animals was chosen for further analysis. After data correction for non-genetic factors (season of calving, period of calving, interaction effect of season and period of calving and age at first calving) these animals were categorised into two groups based on corrected high and low milk fat and protein yields. Forty animals were then selected for blood collection and further laboratory analysis. Amplified using PCR-RFLP technique, the 314 bp STAT1 gene was digested using BspHI restriction enzyme. C-T polymorphism at nucleotide position 201 and 260 of the STAT1 amplicon was observed. At 201, for genotype AA and Aa, the genotypic frequencies were 0.80 and 0.20%. At 260, for genotype BB and Bb, the genotypic frequencies were 0.25 and 0.75%. Least square analysis showed a significant association of all genotypes with milk fat and protein yields. Hence, STAT1 can be used as a potential candidate gene to aid in better animal selection in breeding programmes.
