This research investigated the accumulation of four heavy metals: Pb, Cd, As, and Hg in male and female crabs obtained from four creeks in Bayelsa State and the potential health risks associated with their consumption. The heavy metals were analyzed using Micro-Wave Plasma Atomic Emission Spectrophotometer 4200 Agilent. The mean concentrations of Pb (mg/kg) in the male crabs obtained in Nembe, Taylor, Kolo and Nuno creeks were 41.13±0.17, 31.23±0.12, 38.70±0.33 and 11.63±0.37 respectively, whereas those of the female crabs were 45.63±0.25, 32.00±0.24, 40.00 0.08 and 12.20±0.08 respectively. The mean concentrations of Cd (mg/Kg) in the male crabs from the same creeks were 46.77±0.42, 37.23±0.17, 41.83±0.37 and 28.60±0.29 respectively, whereas those of the female crabs were 47.73±0.37, 39.65±0.45, 45.03±0.25 and 29.40±0.08 respectively. The mean concentrations of As (mg/Kg) in the male crabs from the same creeks were 5.067±0.21, 4.83±0.21, 4.73±0.21 and 1.77±0.12 respectively, whereas those of the female crabs were 6.03±0.17, 5.13±0.17, 5.10±0.08 and 2.07±0.12 respectively. The mean concentrations of Hg (mg/Kg) in the male crabs from the same creeks were 7.87±1.37, 5.57±0.16, 6.80±1.14 and 5.93±0.90 respectively, whereas those of the female crabs were 9.20±0.99, 6.40±0.54, 9.23±1.01 and 6.17 ±0.09 respectively. The concentrations of all the heavy metals were generally higher than the permissible level by Food and Agriculture Organization and World Health Organization in seafood. Statistical analysis of the level of the studied metals showed there is a significant difference p< (0.05). The Total Hazard Quotient (THQ) in all the blue crab in all the creeks were less than 1. The Estimated Metal Intake, Health Risk Index, and Carcinogenic Risk indicated a risk of developing cancer over time due to the ingestion of Pb, Cd, and As. From the results, the health risks associated with exposure to the heavy metals through the consumption of the blue crabs for the inhabitants in the study area are in the order: Pb ˃Cd>Hg>As. Therefore, blue crabs from the creeks under study are considered unsafe for consumption.

Abstract2D polymeric fullerene scaffolds, composed of covalently bonded superatomic C60 nanoclusters, are emerging semiconductors possessing unique hierarchical electronic structures. Hitherto their synthesis has relied on complex and time‐consuming reactions, thereby hindering scalable production and limiting the technological relevance. Here, the study demonstrates a facile electrochemical exfoliation strategy based on the intercalation and expansion of a layered fullerene superlattice, to produce large size (≈52.5 µm2) and monolayer thick 2D polymeric C60 with high exfoliation yield (≈83%). In situ reduction of solvated protons (H+) weakens the interlayer interactions thereby promoting the rapid and uniform intercalation of tetra‐n‐butylammonium (TBA+), ensuring gram‐scale throughput and high structural integrity of exfoliated 2D polymeric C60. As a proof of concept, the solution‐processed 2D polymeric C60 nanosheets have been integrated into thin‐film photodetectors, exhibiting a broad spectral photoresponse ranging from 405 to 1200 nm, with a peak photocurrent at 850 nm and a stable response time. This efficient and scalable exfoliation method holds great promise for the advancement of multifunctional composites and optoelectronic devices based on 2D polymeric C60.

Published: February 2025

AbstractThis paper considers the bipartite consensus (BC) of second‐order delayed multi‐agent systems under signed graphs via aperiodically intermittent control (AIC). Firstly, to break the bottleneck of limited state information from the leader, a novel distributed observer is introduced based on the output information. Secondly, a new aperiodically intermittent controller is designed to achieve the consensus goal and reduce the control cost. By employing inequality techniques and Lyapunov stability theory, some sufficient conditions for ensuring BC of second‐order multi‐agent systems is ultimately obtained. Finally, the effectiveness of the theoretical analysis is demonstrated through a numerical example.

ABSTRACTObjectiveThe objective of this study was to evaluate the feasibility of delivering two psychotherapies for primary care patients with depression.MethodsPatients were referred for psychotherapy from primary care services and were randomly assigned to either Intensive Activation Therapy (IAT; behavioural activation therapy plus cognitive remediation) or Patient‐directed Psychoeducation (PDP; a novel psychotherapy based on the diathesis‐stress model). The interventions were delivered over 10–12 sessions (IAT) and five sessions (PDP). Feasibility was evaluated by recruitment numbers, patient interviews, ability to deliver an adequate dose, managing risk in a non‐medical setting, training new therapists and ensuring treatment fidelity. Mood and functioning were measured at baseline and 12 weeks. Qualitative interviews were conducted at 12 weeks.ResultsIt was feasible to deliver both therapies to primary care patients with severe depression at baseline. Both therapies were effective, with no difference in improving mood and functioning.ConclusionsThis feasibility study suggests that both IAT and PDP can be feasibly delivered in primary care and could be effective in treating severe depression. The next phase will involve training primary care clinicians to deliver the interventions within routine practice and a further study of the effectiveness of the two therapies in routine clinical care.

ABSTRACTObjectivesTraumatic dental injuries (TDIs) are a significant concern in pediatric populations, affecting children's oral health‐related quality of life (OHRQoL) and overall development. This study aims to examine TDI prevalence, types, risk factors, and impacts on OHRQoL among Tanzanian school children.Materials and MethodsEmploying a cross‐sectional analytical approach, the study assessed TDIs in school children aged 8–10 in Ilala district, Tanzania, using a multistage cluster sampling technique. Data collection employed structured questionnaires and clinical examinations, applying Ellis and Davey's classification and the Child Perception Questionnaire (CPQ 8–10) for TDIs and OHRQoL assessments, respectively. Statistical analyses included frequency distributions, chi‐square, Mann–Whitney and Kruskal–Wallis tests, and binary logistic regression.ResultsAmong 501 participants, 25.1% reported previous oral trauma with a TDI prevalence of 37.5%. Crown fractures were the most common injury (79.8%), with significant associations found between TDI prevalence and inadequate lip coverage (p = 0.037) and overjet (p < 0.001). Over 60% experienced an oral impact, notably in oral symptoms (52.5%), emotional well‐being (25.1%), and functional limitation (22.8%) domains. Children with TDIs showed higher OHRQoL impacts on emotional and social well‐being domains.ConclusionsThe high prevalence of TDIs among Tanzanian school children significantly impacts their OHRQoL, emphasizing the need for comprehensive pediatric dental care approaches that encompass preventive strategies and address the multifaceted aspects of oral health.

AbstractIntroductionRetinal vasculometry (RV) provides a neurovascular biomarker which may relate to cognitive status. However, the presence and form of association remains unclear and unexamined at scale.MethodsArtificial intelligence–enabled RV measures from 66,350 UK Biobank study participants were related to combined cognition scores. Differences in RV were examined per standard deviation (SD) increase in cognitive score, using multilevel linear regression, adjusted for age, sex, measurement center, ethnicity, and within‐person RV clustering.ResultsOne hundred ten thousand two hundred eighty‐two retinal images from 63,165 (95%) participants (mean age 56.6 years, 55.5% female) were analyzed. A one SD increase in cognition score was strongly associated with increased arteriolar width, arteriolar tortuosity, increased venular width particularly among those < 50 years and venular area among those > 50 years; also, inversely associated with venular tortuosity, and arteriolar and venular width variance.DiscussionThese easily accessible, affordable, and non‐invasive RV measures should be evaluated further as an early predictor of future neurodegenerative disease.Highlights
How cognitive status relates to retinal vasculometry (RV) measures remains uncertain and unexamined at scale.
Using data from a large population‐based study (UK Biobank) we show strong graded associations between cognitive status and RV, which contrast with some RV associations observed with aging. Specifically, increased arteriolar tortuosity, arteriolar and venular width (at younger ages), and area are positively associated, and venular tortuosity and arteriolar and venular width variability are inversely associated with higher cognitive status, all showing strong, graded, precise relationships. These associations appeared to be strongest for fluid intelligence and prospective memory tests.
These easily accessible, non‐invasive RV measures provide a neurovascular marker indicative of cognitive status, which should be evaluated as early predictors of neurodegenerative disease.

AbstractObjectivesThis study evaluated a novel contrast‐enhanced (CE) fluoroscopy protocol for endoscopic retrograde cholangiopancreatography, which optimizes image processing to enhance contrast of devices and contrast media. We compared the CE protocol with the conventional standard protocol to assess its potential for reducing radiation exposure while improving image visibility.MethodsThe study utilized a multidirectional fluoroscopy unit and phantoms to evaluate the new CE protocol against the conventional protocol. Comparisons included radiation dose rates, spatial resolution, and concentration resolution under various fluoroscopic conditions. The investigation aimed to determine if the CE protocol offered improved visibility while potentially reducing radiation exposure.ResultsThree CE protocol modes (LOW‐7.5 fps, MID‐3.75 fps, and LOW‐3.75 fps) achieved lower dose rates than the standard MID‐7.5 fps mode commonly used in clinical practice. Dynamic spatial resolution was significantly superior in all three CE modes compared to the standard protocol (p < 0.0167). Static spatial resolution did not differ significantly between protocols. Only the CE MID‐3.75 fps mode showed superior concentration resolution compared to the standard protocol (p < 0.00833).ConclusionsThe novel CE fluoroscopy protocol provides superior dynamic spatial resolution in endoscopic retrograde cholangiopancreatopgraphy while reducing radiation exposure, potentially enhancing procedure guidance and safety for both patients and clinicians.
The Comprehensive Analysis of Stratification and Chemical Reaction on MHD Flow Along an Impulsively Started Infinite Vertical Plate in Presence of Radiation and Heat Source Through Porous Medium

Published: February 2025

ABSTRACTThis study analytically investigates the impact of thermal stratification on unsteady magnetohydrodynamic flow along an infinite vertical plate in a porous medium, incorporating chemical reaction, radiation, and heat source. Using the Laplace transform method, exact solutions for velocity, temperature, and concentration profiles were derived, offering a novel approach without approximations. Results show that increased stratification significantly reduces velocity and temperature profiles, with peak velocity decreasing by approximately 35% compared with the nonstratified case (). Higher radiation and Darcy number enhance heat transfer, as reflected in an increased Nusselt number. These findings offer critical insights for optimizing thermal and mass transfer systems in industrial applications, such as cooling processes, energy optimization, and pollution control.
Freeing the Collective Mind: Making Decisions With or Without Group Biases
Authors: Charles Aurelie 
Published: February 2025

Abstract
This chapter shows that group membership and its associated cognitive bias within the self makes the assumption of “individual” decision-making problematic in that it creates a cognitive illusion of the “self” versus “others”, when the self is in essence dynamic and relational. The consequence of such illusion is a mirror effect in resource allocation based on group bias. It makes the whole system of resource allocation entirely reliant on the arbitrary nature of human perception, which differ across individuals. Aggregating group biases at the macro-level then leads to herd behaviour which can have a positive or negative impact on resource allocation, consumption and conservation. Group dynamics can however work towards resource allocation and conservation if decisions are made without group biases at the micro-level, or if group biases are regulated at the macro level.
War and Peace

Abstract
The death of Fred Hall and the outbreak of the Second World War held the College back. But war would nourish a democratic spirit in a highly mobilised country which saw itself as fighting for freedom and the defeat of fascism. Crucially, the College managed to continue operating and attracted younger co-operative employees and members as well as visitors from colonies and soldiers from Poland and Canada. War would also break many of the bonds of empire as colonial peoples asserted the need for their own freedoms which posed challenges for co-operators. In these difficult times, plans for the future gestated, not least for co-operative education. As hurried adjustments and contingencies were being put in place, discussions about the purpose and principles of co-operative education surfaced. Indeed, in the long term, the war gave impetus and vitality to the felt need for a new college. Two world wars within a generation had been a punishing experience that led to demands for a different type of peace. Co-operators were able to take advantage of the centenary celebrations of the Rochdale Pioneers to raise funds to buy a new base for the College, Stanford Hall, an eighteenth-century country estate.
Decline, Crisis and Renewal, 1977–1999

Abstract
The new Principal, Robert Houlton, inherited problems that had been festering for years. Each of the core areas of provision were transformed or squeezed. The College responded with shorter, intensive, in-country, on-site training and consultancy services as well as an early form of access course. But, in the 1990s, the collapse of residential educational study led to vexed exchanges about the very existence of the College. Throughout the period, the College would continue to assert the need for co-operative education while attempting to sustain Stanford Hall. It was a time when the ‘business’ side of the movement predominated and viewed co-operative education as an additional cost. In such unpropitious circumstances, spurred on by the 1994 centenary celebrations, the College developed a new practice and vision of co-operative education, based upon values and principles.
Conclusion

Abstract
The Co-operative College represents an important and unique attempt to bring together forms of education and learning that have been kept separate in wider educational institutions and practices. Social education that focused upon the place and purpose of the co-operative movement within broader social, political, economic and political contexts was a staple of co-operative education for many years. Management and secretarial education was an example of technical learning especially for employees of the movement. Additionally, perhaps the most successful element of the College was the education and training for overseas co-operators that spanned the years of colonialism and independence. As a form of ‘multi-lateral’ institution, it made connections between all these areas of provision. Its vision of co-operation as an educational force based upon a distinctive set of values and principles remains significant.

We study the lattice of submonoids of the uniform block permutation monoid containing the symmetric group (which is its group of units). We prove that this lattice is distributive under union and intersection by relating the submonoids containing the symmetric group to downsets in a new partial order on integer partitions. Furthermore, we show that the sizes of the

Abstract
This paper presents the design, fabrication, and implementation of a single-layer resonant-reflection grating-waveguide structure (RR-GWS) optimized for laser operation in the 2 μm wavelength region. The RR-GWS was designed to function effectively across a broad spectral region ranging from 1.9 μm to 2.1 μm. Reflectance measurements confirmed the structure’s wideband performance within this spectral region, with 99% resonant reflectivity. Incorporating the RR-GWS into a Ho: YAG thin-disk laser system, as a cavity folding mirror, it demonstrated very good power-handling capability and efficacy in wavelength and polarization selection. The 2 μm laser system achieved a linearly polarized output power of 36 W, with an optical efficiency of 34.6%. Additionally, the laser demonstrated a spectral bandwidth of < 0.5 nm full width at half maximum, i.e., 12 times narrower than that obtained with an equivalent all-mirror reference cavity.

Published: February 2025

Abstract

Introduction
Angioleiomyoma, a vascular leiomyoma is a rare, benign smooth-muscle tumor observed to occur anywhere in the body, most frequently in the lower extremities but very rarely in the digestive system. Angioleiomyoma in the hindgut is infrequent and in particular, rectal/perianal location has been observed very rarely.

Case report
We describe herein a case of a 50-year-old male patient complaining of perineal discomfort and a swelling at the level of the left ischio-rectal fossa, moderately painful. This solid mass in the left ischio-rectal space was in close relationship with the wall of the ano-rectal junction. After surgical removal and histopathology, the mass resulted an angioleiomyoma, vascular type, desmin positive, a very rare neoplasm. Extensive immune-histochemical studies are fundamental for the correct diagnosis and to rule out other mesenchymal tumors.
Discussion/conclusion.
Angioleiomyoma is a very rare neoplasm of the gastrointestinal tract, and the fundamental problem of peri-rectal/perianal angioleiomyoma is represented by differential diagnosis from gastrointestinal stromal tumors (GISTs) and other perianal/perirectal swellings. For correct differential diagnosis, the histopathology supported by extensive immune-histochemical study adopting a panel of specific tissue markers is important. The surgical treatment is mandatory with complete excision and subsequent follow-up since local recurrence may occur.

Abstract
Traffic accidents are a major global health and economic concern. As such, research into understanding driving behaviors becomes essential to minimize the associated risks. Among various factors that can influence driving behaviors, listening to music while driving is a complex task that needs investigation. Music can enhance arousal and manage stress, which could potentially improve one’s driving performance. Listening to music, however, also competes for cognitive resources, increasing one’s mental workload and potentially degrading the driving ability. This study investigates the impact of listening to music with different tempos on drivers and their performance using an Artificial Intelligence (AI) approach. A total of 26 participants are subjected to three driving scenarios in a unique simulated experiment, while utilizing a motion platform. The conditions are driving while listening to slow-tempo music, and fast-tempo music, and with no music. A dataset is created by collecting data through Tobii eye-tracking glasses, Equivital sensor belts, and a software tool. This dataset is preprocessed and used to train a convolutional neural network-long short-term memory (CNN-LSTM) model. This model’s performance is optimized through hyperparameter tuning and Chi-squared feature selection, in order to maximize accuracy and minimize computation time. The model performance is compared with those from a densely layered deep learning model and several classical machine learning models. The devised CNN-LSTM model outperforms other machine learning models, achieving an average accuracy rate of 99.29% with minimal variance across multiple evaluations, demonstrating its effectiveness and consistency in classifying drivers’ behaviors under varying auditory conditions.
