      Yang, Peiji; Hao, Jie; Li, Zhiguo; Tchuenbou-Magaia, Fideline Laure; Ni, Jiheng; School of Engineering, Computing and Mathematical Sciences, University of Wolverhampton, Wolverhampton, WV1 1LY, UK (Elsevier BV, 2024-05-20)
      Wind-disturbance is a potential eco-friendly technique for tackling leggy seedlings. This study uses orthogonal experimental design and seedlings vigour assessment by strong seedling index (SSI) to investigate wind-disturbance on regulating tomato seedlings growth. Changes in endogenous hormone levels and biomechanical properties of tomato seedlings were investigated using enzyme-linked immunosorbent assay and uniaxial tension tests. Results showed that factors influencing significantly SSI, in descending order, are wind disturbance time (T), seedling age at the onset of wind disturbance (SA), wind velocity (V), and interval time (I). The wind-disturbance effect was found to be optimal with SSI = 0.126 for a condition where V, T, I and SA values are 3 m s−1, 1 min, 30 min, and 15 days, respectively. V and T were positively correlated with the ethylene and abscisic acid content in seedling leaves, abscisic acid and auxin content in stems, cytokinin and ethylene content in roots, and the elastic moduli of stems and roots but negatively associated with the cytokinin content in stems and leaves, auxin and abscisic acid content in roots, and leaves’ elastic modulus. Wind disturbance mechanism for controlling seedlings growth involved eliciting the accumulation of abscisic acid in stems and leaves and reduction of the auxin content in roots to about the optimal threshold for roots growth thereby reducing seedling stems and leaves development and promoting a better roots growth and a high SSI. This work offers theoretical insights and technical guidance for utilising wind-disturbance as a sustainable seedling cultivation and personalised seedling management approach.
    • Impostors or interlopers? Intersectionality and belonging in mid-career academia

      Mondokova, Andrea; Suresh, Subashini; Renukappa, Suresh; Tsouroufli, Maria; Karodia, Nazira (British Academy of Management, 2024-12-31)
      This developmental paper explores the sense of belonging amongst a frequently overlooked group in higher education, the mid-career academics. The ‘leaky pipeline’ in Science, Technology, Engineering, and Mathematics (STEM) academia is a widely accepted phenomenon affecting women and minorities and whilst much of the efforts to date focus on the bottom-up approach by increased recruitment of future STEM academics, this project seeks to focus on the often-forgotten middle part of the pipeline. In an effort to transform academia for the better and to remove any societal, organisational and personal barriers continuously experienced by students and staff, it is essential that all groups receive an equal amount of attention. Therefore, this research seeks to fill the gap in understanding of lived experiences of mid-career STEM academics. This qualitative study sets out to understand how the intersectional self-identification of participants impacts their experiences of (non)belonging in UK higher education. Following the initial stages, the project intends to explore the raised issues in more depth, as well as to expand its reach to include participants from across more UK universities. This will be done to evaluate their experiences of the identified themes and to gauge their proposed solutions. In the long term, the research seeks to develop a blueprint for sustainable solutions towards improving the work environment of academic colleagues employed at post-92 institutions.

      Daniel, Emmanuel; Oshodi, Olalekan Shamsideen; Marte Gomez, Jose; Marte Gomez; School of Architecture and Built Environment, University of Wolverhampton, Wolverhampton, UK (ICE Publishing Ltd., 2024-05-08)
      Shortage of workforce stifles innovation and increases project costs. Information gleaned from literature shows that the ageing workforce and inability to attract young people are reasons for labour shortages in the engineering sector. To address this shortage, several countries have created various programs, such as degree apprenticeship, to ease the process of recruiting, training and retaining young people. The current study seeks to: (i) uncover factors influencing the decision to sign-up for degree apprenticeship programs and (ii) unearth the factors affecting the outcome of degree apprenticeship programmes in engineering. Interviews were conducted to address the research objectives of the study. The findings indicated that awareness, covid-19 pandemic, funding, incentives [financial and non-financial] and diversity are key factors influencing the decision to sign-up for degree apprenticeship. Also, demand for engineering jobs, balance between theory and practical training, collaboration of stakeholders, leadership support, versatility of apprentice experience are the factors affecting the outcome of degree apprentices. Based on the findings, it is evident that raising awareness among stakeholders, such as career counsellors, and collaboration are vital for improving the supply of qualified young people in the engineering sector.
    • Rainwater quality analysis for its potential recovery: a case study on its usage for swimming pools in Poland

      Lempart-Rapacewicz, Anna; Zakharova, Julia; Kudlek, Edyta (MDPI, 2023-10-19)
      This paper describes the possibility of using rainwater for filling artificial swimming pools in Poland. The overall purpose of this study is to understand whether the quality of rainwater collected from roofs would be suitable for use in the swimming pools without any additional treatment. The rainwater samples were collected from five areas in the Silesian region and analysed for a number of physico-chemical parameters. The results show that the content of nitrates met Polish standards, whereas the standards set for pH and turbidity would only be met after the water had undergone the treatment process which takes place in every swimming pool installation. The paper further compares rainwater data from this study with the corresponding data for drinking water and groundwater. It shows that the content of ammonia, some metals (Ni, Cr and Mn) and a semimetal are in line with the parameters used for drinking water and are a lot lower compared to those set for groundwater. However, the results indicated some possible consequences which might be harmful for swimming pool users. These include the adverse effects of zinc and other organic micropollutants which are classified as contaminants of emerging concern (CECs). These may form dangerous byproducts in the presence of the chlorine, the use of which is required by the standards to be applied for swimming pool disinfection purposes.
    • Chronic pain evaluation in breast cancer patients using the Self-Report Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS): a single center cross-sectional retrospective study

      Daga, Dhiraj; Shah, Narender Singh; Jain, Sanchit; Sharma, Gaurav; Goel, Harsh; Tavolacci, Sooyun Caroline; Gupta, Boski; Gulia, Kiran; Khan, Tabish H; Usmani, Darksha; et al. (VM Media Group sp. z o.o, 2023-07-13)
      Background: Breast cancer is the most common cancer in India, and the number of survivors has increased over the last few years. Pain is one of the most common symptoms during cancer treatment due to either the disease itself or the adverse effects of treatment. The available data suggests that breast cancer patients have a high prevalence of neuropathic pain. Patients and methods: A cross-sectional observational study was done at the Department of Radiation Oncology, between November 2021 to June 2022. The patients were admitted and screened for participation, non-metastatic post-operative breast cancer on regular follow-up for 2 years after their last chemotherapy or radiotherapy and not having any chronic neuropathy disease and the Self-Report Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS) pain scale was used to assess the neuropathy pain status of patients. Patients’ demographics, clinical characteristics, and treatment of surgery, radiation therapy, and chemotherapy were collected and the comparison of the pain scores between the patients was analysed. Results: A total of 149 patients were included in the study. S-LANSS score was calculated in the study population and more than 61% of participants reported a score equal to or greater than 12, suggesting a predominant neuropathic pain component. Autonomic dysfunction, thermal pain, and allodynia were more prevalent in patients who underwent mastectomies compared to breast-conserving surgery. Whereas the dysesthesia and autonomic dysfunction score was higher in only the anthracycline group. Conclusions: The most important index for quality of life in cancer patients is the presence of persistent chronic pain and it is important to classify it accordingly in order to provide the best management. Using the S-LANSS score, the pattern of neuropathic pain can be determined early which leads to early intervention.
    • An overview of fatty acids-based nutritional quality indices of fish oils from Cameroon: impact of fish pre-treatment and preservation methods

      Dongho Dongmo, Fabrice Fabien; Fogang Mba, Aymar Rodrigue; Njike Ngamga, Fabrice Hervé; Djeukeu Asongni, William; Zokou, Ronice; Simo Noutsa, Boris; Ngo Hagbe, Diana; Tchuenbou-Magaia, Fideline Laure; Ebelle Etame, Rebecca Madeleine (Elsevier, 2024-04-12)
      This research provides a comprehensive examination of fish oils obtained from different fish species in Cameroon. It meticulously evaluates their nutritional quality indices based on fatty acids profile and scrutinizes the impact of diverse pre-treatment procedures on these indices. The fatty acid profiles and nutritional quality indices of seventeen fish species were reviewed, with a focus on the impact of refrigeration, boiling, and drying. The use of both synthetic and natural antioxidants in preserving oil quality during drying was also examined. The oil from Fontitrygon margarita liver had the highest nutritional quality, followed by oils from the fillets of seven other species. However, oils from certain species were found to have poor nutritional quality due to an unacceptable polyunsaturated fatty acids/saturated fatty acids ratio, atherogenicity index hypocholesterolemic/hypercholesterolemic ratio, and other parameters. Interestingly, boiling was found to enhance the nutritional quality of fish oil, while refrigeration and drying appeared to degrade it. Natural antioxidants, especially aqueous spices extracts, proved to be as effective, if not better than synthetic ones in preserving oil quality. Overall, this research enhances our understanding of the health benefits of fish oils and offers valuable insights into optimal oil extraction and preservation practices.
    • Oligopeptide-based molecular labelling of (bio)degradable polyester biomaterials

      Rydz, Joanna; Duale, Khadar; Sikorska, Wanda; Musioł, Marta; Janeczek, Henryk; Marcinkowski, Andrzej; Siwy, Mariola; Adamus, Grażyna; Mielczarek, Przemysław; Silberring, Jerzy; et al. (Elsevier, 2024-04-21)
      Nowadays, a very important motivation for the development of new functional materials for medical purposes is not only their performance but also whether they are environmentally friendly. In recent years, there has been a growing interest in the possibility of labelling (bio)degradable polymers, in particular those intended for specific applications, especially in the medical sector, and the potential of information storage in such polymers, making it possible, for example, to track the ultimate environmental fate of plastics. This article presents a straightforward green approach that combines both aspects using an oligopeptide, which is an integral part of polymer material, to store binary information in a physical mixture of polymer and oligopeptide. In the proposed procedure the year of production of polymer films made of poly(l-lactide) (PLLA) and a blend of poly(1,4-butylene adipate-co-1,4-butylene terephthalate) and polylactide (PBAT/PLA) were encoded as the sequence of the appropriate amino acids in the oligopeptide (PEP) added to these polymers. The decoding of the recorded information was carried out using mass spectrometry technique as a new method of decoding, which enabled the successful retrieval and reading of the stored information. Furthermore, the properties of labelled (bio)degradable polymer films and stability during biodegradation of PLLA/PEP film under industrial composting conditions have been investigated. The labelled films exhibited good oligopeptide stability, allowing the recorded information to be retrieved from a green polymer/oligopeptide system before and after biodegradation. The MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide assay) study of the PLLA and PLLA/PBAT using the MRC-5 mammalian fibroblasts was presented for the first time.
    • FGF23 expression is a promising immunohistochemical diagnostic marker for undifferentiated pleomorphic sarcoma of bone (UPSb)

      Al-Hassi, Hafid O; Ali, Naser M; Cooke, Hannah; De Silva, Shamini; Brini, Anna T; Babu, Pavithra; Sumathi, Vaiyapuri; Morris, Mark R.; Niada, Stefania; Research Institute of Healthcare Science, Faculty of Science and Engineering, University of Wolverhampton, Wolverhampton WV1 1LY, UK; et al. (MDPI AG, 2024-02-14)
      Background: Undifferentiated pleomorphic sarcoma of bone (UPSb) is a rare primary bone sarcoma that lacks a specific line of differentiation. Distinguishing between UPSb and other malignant bone sarcomas, including dedifferentiated chondrosarcoma and osteosarcoma, is challenging due to their overlapping features. We have previously identified that UPSb tumours have elevated mRNA levels of Fibroblast Growth Factor 23 (FGF23) transcripts compared to other sarcomas including osteosarcoma. In the present study, we evaluated the specificity and practicality of FGF23 immunoreactivity as a specific diagnostic tool to differentiate UPSb tumours from osteosarcomas and dedifferentiated chondrosarcomas. Methods: A total of 10 UPSb, 10 osteosarcoma, and 10 dedifferentiated chondrosarcoma cases (all high-grade), were retrieved and immunohistochemistry for FGF23 was performed. Results: FGF23 protein was expressed at high levels in 80–90% of undifferentiated pleomorphic sarcoma of the bone cases, whereas it was expressed at significantly lower levels in dedifferentiated chondrosarcoma and osteosarcoma cases. A semiquantitative analysis, considering the intensity of immunoreactivity, confirmed significantly elevated FGF23 expression levels in UPSb tissues compared to those observed in osteosarcoma and dedifferentiated chondrosarcoma tissues. Conclusions: The results we present here suggest that FGF23 immunohistochemistry may be a useful tool to aid in differentiating UPSb from morphologically similar malignant bone sarcomas, especially in situations where sampling is restricted and there is limited clinical information available.
    • Differential responses of Hollyhock (Alcea rosea L.) varieties to salt stress in relation to physiological and biochemical parameters

      Sadeghi, Arezoo; Razmjoo, Jamshid; Karimmojeni, Hassan; Baldwin, Timothy C; Faculty of Science and Engineering, University of Wolverhampton, Wulfruna St, Wolverhampton, WV1 1LY, UK (Springer Science and Business Media LLC, 2024-04-06)
      The response of 14 Hollyhock (Alcea rosea L.) varieties to salinity were evaluated in a field experiment over two growing seasons. Carotenoid, Chl a, Chl b, total Chl, proline and MDA content, CAT, APX and GPX activity and petal and seeds yields were determined in order to investigate the mechanism of salt tolerance exhibited by Hollyhock, and too identify salt tolerant varieties. Overall, the photosynthetic pigment content,petal and seed yields were reduced by salt stress. Whereas the proline and MDA content, and the CAT, APX and GPX activities increased as salt levels increased. However, the values of the measured traits were dependent upon the on the level of salt stress, the Varietie and the interaction between the two variables. Based upon the smallest reduction in petal yield, the Masouleh variety was shown to be the most salt tolerant, when grown under severe salt stress. However, based upon the smallest reduction in seed yield, Khorrmabad was the most tolerant variety to severe salt stress. These data suggest that the selection of more salt tolerant Hollyhock genotypes may be possible based upon the wide variation in tolerance to salinity exhibited by the varieties tested.
    • Mental health of mothers with malnourished children in Nepal: a prospective observational study

      Sharma, Asmita; Sharma, Yograj; Thapa, Asha; Kar, Nilamadhab (Nepal Health Research Council, 2024-03-31)
      Background: Maternal mental health may influence the nutritional status of their children. It was intended to assess the mental health status of the mothers of children admitted to a nutrition rehabilitation center. We specifically explored the relationship between maternal mental health and malnutrition of the child; to observe any change of maternal depressive/anxiety symptoms and weight gain in the child following admission. Methods: In a prospective observational study, malnutrition of children was assessed based on weight for height z scores using the WHO Anthro-Survey-Analyser. We evaluated anxiety using the Generalized Anxiety Disorder Scale (GAD-7) and depression by Patient Health Questionnaire (PHQ-9). Demographic and clinical variables were collected. Results: The degree of malnutrition of the children at admission and discharge was: mild (3.6% v 31.7%), moderate (37.7% v 26.3%), severe (58.7% v 8.4%), and no malnutrition (0.0% v 33.5%) (p<0.001). At admission, 12% of mothers had anxiety, depression, or both, which decreased to 3.0% at the time of discharge. There was no difference in malnutrition scores among children of mothers with or without anxiety/depression at admission or discharge, except that children of depressed mothers continued to have significantly greater levels of malnutrition at discharge compared with the mothers without depression. Maternal anxiety or depression was not associated with the severity of malnutrition. Conclusions: A proportion of mothers of children with malnutrition had clinical anxiety and depression; and maternal mental health concerns, especially depression may influence the nutrition of children. It is imperative to explore maternal mental health routinely for malnourished children.
    • Quality of life and well-being of dermatology patients: Influence of associated anxiety and depression in relation to satisfaction of care

      Mohapatra, Prasanta; Sahu, Piyush; Mohapatra, Ankita; Kar, Nilamadhab (Medknow Publications, 2024-03-11)
      Background: Many patients attending dermatology clinics have mental health problems which may affect their well-being. Aims: It was intended to study the influence of anxiety and depression on well-being and quality of life (QOL) in relation to satisfaction of dermatological care in an out-patient setting. Materials and Methods: In a cross-sectional study, dermatological patients were assessed for well-being (WHO-5 Well-Being scale), overall QOL, anxiety (General Anxiety Disorder, GAD-7), and depression (Patient health questionnaire, PHQ-9). Satisfaction of care in the dermatology clinic (1: not at all satisfied to 10: very satisfied) and the likelihood of recommending it (1: not at all likely to 10: very likely) were assessed on a 1 to 10 scale. Demographic and clinical variables were also collected. Results: The sample (n = 150) covered a range of dermatological diagnoses including allergy/eczema (53.3%), inflammatory/infective diseases (19.3%), sexually transmitted diseases (10.0%), psycho-somatic diseases (9.3%), and auto-immune diseases (7.3%). A clinically relevant level (moderate degree or above) of depression (12.7%) and anxiety (8.0%) was present in considerable proportions of patients, suggesting that overall 18.7% of patients had anxiety, depression, or both. The satisfaction and recommendation scores were at an appreciable level; however, they did not influence the anxiety and depression scores. Anxiety and depression were negatively correlated with well-being and overall QOL. Conclusion: Anxiety and depression present in a considerable proportion of dermatological patients significantly impaired their well-being and QOL despite high satisfaction and likelihood of recommendation of care in the dermatology clinic. Identifying and supporting psychiatric problems of dermatological patients are needed.
    • Public education for mental health: Revisiting its intervention potential

      Kar, Nilamadhab (Medknow Publications, 2024-03-18)
      It is well known that public knowledge about mental illnesses is not at an expected level, and misinformation and stigma continue to be commonplace. These factors have a negative impact on appropriate and timely help seeking, adherence to treatment, and consequently on the clinical outcomes. There are robust public education materials and resources available through various platforms, such as the print and electronic media and the Internet. In fact, there is information overload, and a considerable proportion of the information is inaccurate, unscientific, and unreliable. Considering this, there is a need for appropriate guidance to be provided by the mental health professionals to the patients, caregivers, and general public. Public education for mental health is not only helpful but is also an effective intervention that is not adequately used. It should be actively encouraged and practiced routinely. This may improve the mental health literacy of the general public; the help seeking, engagement, and adherence of the patients with the treatment process would possibly be better, and these may help the intervention and outcome of mental illnesses.
    • Impact of disasters on the disaster responders: A review of stress, coping, resilience, and supportive methods

      Kar, Nilamadhab (Medknow Publications, 2024-03-18)
      As disasters are becoming more common, there is an ever-increasing need for support from personnel working in those situations, from search and rescue to emergency health care, relief, and postdisaster short- and long-term support. Exposure to traumatic situations affects disaster responders psychologically for various reasons and to different degrees. These mental health sequelae need to be identified, and the responders should be appropriately supported. A narrative review was conducted from the available literature in this regard. There are reports of the impact of disaster stress on disaster responders, and many have short- and long-term consequences. These are mostly anxiety, depression, and posttraumatic stress. In some cases, it might impair their effectiveness in disaster work. There is information about improving preparedness for disaster exposure, coping strategies, and effective psychological intervention methods for the responders. However, the availability and adequacy of the support system in various situations are not clear. The impact of disaster trauma on disaster responders needs to be extensively studied and support systems should be in place to manage the negative psychosocial outcomes.
    • Profile of nonattending patients at psychiatric outpatient clinics before (in-person model) and during COVID-19 pandemic (telepsychiatry model): A comparison study

      Kiani, Mahum; Kar, Nilamadhab (Medknow Publications, 2024-03-18)
      BACKGROUND: Missed appointments in mental health services have been a concern; as nonattendance may be associated with various clinical risk factors. AIMS: We intended to compare the profile of nonattenders at psychiatric outpatient clinics before (in-person model) and during the COVID-19 pandemic when the services changed to remote consultations (telepsychiatry model). MATERIALS AND METHODS: Clinical features (diagnosis, medical and psychological treatment, care program approach, and first contact), risk to self and others, and demographic variables (age, gender, ethnicity, accommodation, occupation, and benefits) were collected from the electronic records. The outcomes after the missed appointment were also noted. RESULTS: The sample consisted of 23 nonattenders in January 2020 (pre-COVID-19) and 32 nonattenders in November 2020 (during COVID-19); with an overall rate of nonattendance of 20% and 22%, respectively. Nonattenders during COVID-19 were significantly (P < 0.05) younger (36.4 ± 10.2 vs. 45.3 ± 15.0), and had more male patients (68.8% vs. 31.3%) compared to pre-COVID-19. There were no differences in other demographic variables, diagnoses, treatment received, or level of care. Risk to self was significantly more during COVID-19 (34.4% vs. 8.7%, P < 0.05) and risk to others was less (0.0% vs. 17.4%, P < 0.05). Significantly more (P < 0.05) nonattenders were contacted by letters during COVID-19 (81.3%) than pre-COVID-19 (52.2%); a higher (P < 0.05) proportion of nonattenders were discharged from services during COVID-19 (34.4%) compared to pre-COVID-19 period (8.7%). CONCLUSIONS: During COVID-19, when psychiatric outpatient services changed to remote consultations, there were differences in the profile of nonattenders and their risks. The results suggest that telepsychiatry services should explore the profile of nonattenders and their risks for arranging appropriate support.
    • Assessment and documentation of substance abuse by crisis resolution home treatment team: A quality improvement project

      Raja, Usman; Misra, Anurag; Kar, Nilamadhab (Medknow Publications, 2024-03-18)
      AIM: Substance abuse is associated with mental health crises, leading to increased attendance in A and E and hospital admissions. This quality improvement project (QIP) evaluated the assessment and documentation of substance abuse of patients admitted under the crisis resolution home treatment team (CRHT) as well as any change following a teaching session as an intervention. METHODS: Data from 40 consecutive patients admitted under the CRHT from the 1st of September 2023 were collected. The CRHT uses the “Core Crisis Resolution Team Fidelity Scale” as the standard of practice and this was utilized as the benchmark for the QIP. A teaching session for nursing staff was conducted as an intervention. Following the teaching session, the second cycle of data was collected from 40 consecutive patients. RESULTS: Substance abuse was documented by CRHT in 30% of patients (12/40). However, the proportion was 70% (28/40) when documentation by other secondary services, such as mental health liaison, community mental teams, and the sources of referral were considered. Following the educational session, CRHT documented substance abuse for 37.5% (15/40). When documentation by secondary services was checked, the percentage of patients with documented substance abuse was 67.5% (27/40). CONCLUSION: The QIP suggested a minor improvement in the documentation of substance use after the educational session of the nurses. Multiple sessions of sessions, a longer period before reassessment to allow change of practice, and a prompt in the evaluation document might improve the assessment and documentation of substance use by the patients in CRHT.
    • Exploring international perspective on factors affecting urban socio-ecological sustainability by green space planning

      Teimouri, Raziyeh; Karuppannan, Sadasivam; Sivam, Alpana; Gu, Ning; Yenneti, Komali (MDPI, 2023-09-25)
      Urban green space (UGS) is one of the most important components of urban systems to create sustainable cities. This crucial urban element performs many social and ecological functions to facilitate a better quality of life for urban residents. The main aim of this study is to identify the most critical factors contributing to cities’ social and ecological sustainability through UGS planning and development. To achieve this aim, an integrated socio-ecological approach was followed to collect and analyse the data, which comprised context analysis and an international experts survey. Therefore, firstly, the main influencing factors for urban social and ecological sustainability that can be achieved by UGS planning were extracted by reviewing the related literature. In the next step, to find the most critical factors, an online international survey of academicians and experts drawn from a number of countries was conducted. Based on the experts’ opinions, twenty-two factors out of sixty-five, including twelve social factors and ten ecological factors, achieved the highest scores. According to the results, the key factors of accessibility from the social sustainability category and protection from the ecological sustainability category play the most important roles in maximising the social and ecological benefits of UGS.
    • Are current UK coastal defences good enough for tomorrow? An assessment of vulnerability to coastal erosion

      Kantamaneni, Komali; Rice, Louis; Du, Xiaoping; Allali, Belqais; Yenneti, Komali (Taylor & Francis, 2022-01-16)
      Coastal vulnerability and its physical, economic and social consequences at national and international scales is of high scientific, political and policy interest. Anthropogenic climate change and coastal erosion threaten the very fabric of a society. Indications, that coastal hazards are impacting diverse coastal areas severely across the world, and it is no longer a vague future threat that can’t be ignored. Rising eustatic sea levels synthesized by the growing frequency and scale of coastal hazards like storm surges, coastal erosion and coastal landslides threaten low-lying and unprotected coastal areas in the United Kingdom even if they have coastal defenses. However, there is still significant uncertainty about the degree of vulnerability along different coastal stretches, particularly in England. To fill this uncertainty, the current study estimated the coastal vulnerability of the coastal erosion hotspot Camber, England, by establishing a coastal vulnerability index. This index was developed by compounding various existing parameters and termed as Erosion Coastal Vulnerability Index (ECVI). Results illustrate that 67% of coastal area fall between high and very high vulnerability categories, and current coastal defenses are not strong enough to tackle the severe coastal erosion in Camber. Within the evaluation, thematic maps were generated to enable the intensity of the vulnerability for different coastal stretches to be identified. The evaluated vulnerable hotspot should be treated urgently by regional and national policy organizations to ameliorate the impacts of coastal erosion and other associated risks. Without action, the hotspot is likely to encounter unprecedented new vulnerabilities, disasters and humanitarian catastrophes. The current study results allow for a local, regional and national comparison that may help to evaluate changes in coastal erosion vulnerability.
    • Wind flow and its interaction with a mobile solar PV system mounted on a trailer

      Eslami Majd, Alireza; Adebayo, David Shina; Tchuenbou-Magaia, Fideline Laure; Willetts, James; Nwosu, Dave; Matthews, Zachary; Ekere, Nduka Nnamdi (MDPI, 2024-02-29)
      Efficient implementation of clean energy technologies is paramount, with mobile solar PV systems on trailers (MSPTs) emerging as pivotal solutions, particularly in regions with limited power grid access. This endeavour is vital for meeting escalating electricity demands and aligning with the UN Sustainable Development Goal (SDG), aimed at ensuring dependable and sustainable energy provision in developing countries. This study investigates the aerodynamic behaviour of a designed MSPT using numerical simulation and experimental methods, thereby offering optimization potential for MSPT design and enhancing overall performance and reliability. Specifically, the study focuses on the effects of wind velocity and tilt angles on the drag and lift forces, as well as drag and lift coefficients on the panel used in the MSPT system. The overall wind force on the entire MSPT, including nine large solar PV panels, is scrutinised, considering combined wind flow and system geometry effects. The numerical investigations were conducted using ANSYS-Fluent software (version 2022/R2) and experimental testing was performed within the C15-10 Wind Tunnel, utilizing scaled-down models to validate the accuracy of the simulation. The findings from the numerical investigations showed an increased turbulence caused by gaps between panels, resulting in almost 62% higher suction flow velocity and 22% higher suction pressure compared to a single panel. Drag and lift forces on the entire MSPT were approximately 6.7 and 7.8 times greater than those on a single panel with the same 30-degree tilt angle, respectively. The findings revealed that scaling forces on a single panel is insufficient for accurately predicting the aerodynamic forces on the entire MSPT. The insights and the knowledge from this study pave the way for further improvements in mobile solar PV technology.
    • An herbal tea blend of hibiscus sabdariffa, zingiber officinale, and mentha spicata: a potent source of antioxidant and anti-obesity properties

      Dongho Dongmo, Fabrice Fabien; Nkepndep Touohou, Suzie Vanissa; Ebelle Etame, Rebecca Madeleine; Lienou Lienou, Landry; Manz Koule, Jules Christophe; Goeithe Mbiatat, Hilaire De; Tchuenbou-Magaia, Fideline Laure; Gouado, Inocent (AMO Publisher, 2024-01-01)
      Background: There is an urgent need to find safer and more sustainable solutions to tackle the rising global epidemic obesity and associated complications. The main objective of this study was to develop formulations of herbal tea blend from three plant species and to assess the antioxidant and antiobesogenic properties of the best formulation. Methods: The best formulation (FX) obtained (80% Hibiscus sabdariffa, 10% Zingiber officinale and 10% Mentha spicata) was validated by their better sensory acceptability and antioxidant properties. In vivo study using high-fat diet Wistar rats revealed that FX alleviated oxidative stress and metabolic disorders including those affecting hepatic and renal functions caused by high-fat died. Results: The administration of FX resulted in a reduction in food intake, body weight gain and metabolic efficiency index alongside lower blood content in triglycerides, total cholesterol, LDL-cholesterol, glucose, and atherogenic index when compared to the control groups. The results were comparable if not better than those obtained from the reference groups treated with a standard obesity treatment medicine, Orlistat. Conclusion: The developed herbal blend showed promising results for use as a safer product for obesity prevention and management as well as other oxidative stress-related health issues.
