Leachate, which refers to the contaminated fluid that results from water percolating through a landfill or waste disposal site, is a significant concern in sub-Saharan Africa. The uncontrolled release of leachate, particularly from dumpsites, is a primary contributor to groundwater pollution in the region. This research aimed to assess the impact of solid waste dumpsites on groundwater quality, specifically focusing on the landfill at Mkpuka Obosi. The study area was divided into eight concentric cells (C1-C8), each containing water and soil samples for analysis. The parameters examined include Temperature (OoC), pH, Iron (Fe2+), Lead (Pb2+), Copper (Cu), Zinc (Zn2+), Calcium (Ca), Sodium (Na), Magnesium (Mg2+), Suphate (SO2-4), Chloride (Cl-), Nitrate (N03-), Biocarbonate (HCO), Total Dissolved Solid (TDS), Biological Oxygen Demand (BOD), Total Suspended Solid (TSS), Chemical Oxygen Demand (COD), Total Hardness (TH), Electrical conductivity (EC), for the water analyses, while for soil analyses, pH values, Total organic carbon, Iron, Zinc, Temperature, Sand, Slit, Clay, Electric conductivity and copper were analyzed. The results were compared with relevant standards set by organizations like the World Health Organization (WHO). The findings indicated that parameters such as chemical oxygen demand, total suspended solids, chloride, nitrate, sodium, calcium, copper, lead, iron, and electrical conductivity exceeded the recommended standards. This suggests that water contamination from the dumpsite has adversely affected groundwater quality. Analysis of the graphs and tables revealed that the contamination spread decreased proportionally with distance from the dumpsite. As a result, water within approximately 500 m of the centre of the landfill was deemed unsuitable for consumption due to health risks and hazards. The water quality index ranged from 13 to 513, indicating that wells and boreholes located around 500 m from the dumpsite require significant treatment before being considered safe for consumption. The excess presence of sandy soil in the area, attributed to the geological formation, was found to contribute to the rapid flow of contaminants from the dumpsite. Coarse textured soils, being more permeable, have lower sorption potentials, while fine textured soils have slower permeability and higher sorption potentials. Consequently, the high proportion of coarse sandy soil surrounding the landfill favours the accelerated movement of contaminants.

This study investigates the groundwater potential in Opolo-Epie, Yenagoa, Bayelsa State, Nigeria, deploying electrical sounding (VES) surveys and borehole log data analysis. Utilizing the Schlumberger electrode configuration and Terrameter SAS 1000 instrument, coupled with the Global Positioning System (GPS), three VES profiles were conducted and processed using IPI2win software and Starter 5. Key findings from the study reveal promising subsurface features and groundwater prospects. VES 1 identified distinct zones of fine to medium sand with resistivity value of 0.62-28.7 Ωm with a depth of (17.4–47.2 m) and coarse sand with resistivity value of 359 Ωm and a depth of (47.2–56.2 m). VES 2 indicated potential aquifers in the medium sand with resistivity value of 368.4 Ωm with a depth of (5.48–11.45 m) and coarse sand with resistivity value of 1089 Ωm and a depth (11.45-23.92 m), while VES 3 delineated a shallow aquifer in the fine sand layer with a resistivity of 117.4 Ωm and depth zone of (1.92–5.19 m) and a deeper, more promising aquifer in the coarse sand zone with resistivity value of 1680 Ωm and depth of (11.13–22.66 m). Borehole logging confirmed significant sand layers (3–30 meters) with potential for water storage and flow, along with a clay layer (27.1–30 meters) acting as a confining unit for underlying groundwater. The correlation between VES and borehole data revealed consistency in identifying clay layers but discrepancies in interpreting deeper aquifer zones, underscoring VES limitations in resolving thin layers. The study underscores the importance of integrating VES surveys with borehole data for a comprehensive evaluation of groundwater resources. Notably, the borehole logging-identified coarse sand layer (33.3–42.4 meters) appears to be an attractive prospect for a productive aquifer; therefore, additional research is necessary to resolve interpretational differences and determine whether clay layers exist and how thick they are in this zone.

Mineral is an inorganic element required in minute quantity as an essential nutrient by living organisms to undertake functions necessary to sustain life. Minerals include iron, potassium, nitrogen, calcium, phosphorus, sodium, and sulfur. The formation of soils during weathering processes contributes greatly to the biogeochemical cycling of these elements. Sedimentary rocks have been the most important soil parent materials and thus, the accessibility of mineral nutrient elements to plants is dependent on the ease of weathering of rocks as well as their compositions. The process of weathering is in turn influenced by lithology which makes available new mineral elements of different reactivity for weathering reactions. Natural sources such as soil and water are the two most important sources of mineral nutrient elements for plants. The ability of soil to supply the plants with important nutrient mineral elements as well as the production of quality agricultural crop produce in a given community is all linked to the parent material a soil originated from. In this review, the functions of some mineral elements, accessibility and bioavailability of mineral nutrient elements to plants are discussed. The distribution and influence of lithology and parent materials on crop production in plants are also elucidated.

Urbanization has destroyed wetlands globally, and in the Niger Delta area surge in human population has led to increased encroachment into wetlands area resulting in habitat destruction. This research aims to determine the impact of urbanization on selected wetland areas at Eagle Island, Rivers State. The study was carried out between April 2023 and January 2024. Physico-chemical parameters were assessed using standard procedures. The results of the water quality assessment show the range of temperature, dissolved oxygen, and pH to be within acceptable limits for tropical waters as recommended by WHO, while others, including total dissolved solids and electrical conductivity (µS/cm), were not within acceptable limit as stipulated by WHO. The mean concentration of heavy metals, nitrates, and phosphate in surface water was within the NUPRC permissible limits. The mean concentrations of cadmium, chromium, and lead in sediment were higher than the NUPRC permissible limits, while nickel, iron, nitrate, and phosphate were within the NUPRC permissible limits. The concentration of metals in surface water were: Cd= 0.014 µg/l, Cr = 0.219 µg/l, Ni = 0.651 µg/l, Pb = 0.160 µg/l, Fe = 1.881 µg/l, in the order of Fe>Ni>Cr>Pb>Cd. The result implies that there is a gradual deterioration of environmental quality as a result of human-mediated activities. The soil and water quality in wetland areas are facing degradation because of the unprotected intrusion of private individuals and organizations who enter to carry out the sand filling, swamp reclamation, and construction activities, leading to the loss of wetlands and river systems.

Based on the selection and development of exploration areas and the detection and mapping of mining areas, remote sensing has been used more frequently to acquire information about a geographic area of interest. Remote sensing-based applications reduce the need for field work and ultimately save costs. This effort explores the potential of remotely sensed digital data in highlighting mineralized zones through hydrothermal alteration studies. Landsat 8 OLI data covering the investigated area was used to detect and map locations of hydrothermal alterations. Image processing methods used were spectral enhancement, false colour composites, band rationing and Principal Component Analysis. Results of false colour composites (FCC) of band ratio highlighted generally locations of hydrothermal alterations. The band ratios image of Sabin’s (6/7, 4/2, 4/6, and 4/6 in red–green–blue) revealed the presence of ferric, clay-rich, and ferrous iron minerals, respectively. The principal Components (PCs) of two sets of images (4, 5, 6, 7 H-image and 2, 3, 4, 5 F-image) were generated depicting iron-oxide and hydroxyl mineral deposits as bright pixels. The colour composite of H, F and H+F images enhanced the location of the mineral deposits by showing areas of mineralization in dark blue (clay-rich), bright yellow (Fe-rich), and white (alteration zones in bright reddish to orange) pixels. Fieldwork, previous remote sensing studies, and laboratory analysis were used to verify the image processing results. The remote sensing applications with field geochemical data results show that the spectral and spatial analysis of optical multispectral data in mineral exploration investigations is strengthened. This study recommends the use of remote sensing and geospatial technology in mineral studies through hydrothermal alteration within the basement complex rocks of the Arabian Nubian Shield.

Ecological evaluation was carried out to study the surface water of the Kaani River, Ogoni axis, Rivers State, South-South, Nigeria, for contamination factor (Cf), degree of contamination (Cd), and modified contamination degree (mCd). Over the course of a year, surface water samples were taken from the Kaani River at four separate locations every two months. The atomic absorption spectrophotometry (AAS) method was used to determine the amounts of heavy metals in the samples after they had been prepared according to normal procedures. The metals analyzed were manganese (Mn), cadmium (Cd), copper (Cu), chromium (Cr), lead (Pb), iron (Fe), zinc (Zn), arsenic (As), and nickel (Ni) respectively. The result of the metal concentrations in all stations and months showed the order as As < Cd < Pb < Mn < Cr < Ni < Zn < Fe < Cu. A contamination factor test on the various heavy metals based on their concentrations and the WHO standard revealed that the studied heavy metals were at different levels of contamination and pollution classification in the River at different stations. The values observed for all the trace elements studied, with the exception of Fe, were less than the WHO and NAFDAC requirements for drinking water. The River showed no contamination–moderate pollution with Fe, while that of Mn indicated slight contamination- severe contamination range, Cd fell within no contamination to slight contamination range, slight contamination –slight pollution with Cu, no contamination – slight contamination with Zn, slight contamination – very severe contamination with Cr, moderate contamination- very severe contamination with Pb. As and Ni were at the range of slight contamination – moderate contamination. The analysis results from the River indicated that the water should be treated adequately before consumption. The pollution index analysis showed that the River was not polluted with heavy metals. Contamination degree values showed that the River is at different levels of heavy metal contamination. Modified contamination degree indicated that the River experienced nil to very low degree of contamination by the metals examined.

This study examined semi-unconsolidated surface outcrop samples from three different localities within the Agwu Formations of the Lower Benue Trough (SE Nigeria). This paper focuses on the palynology, petrographic composition and depositional conditions of the three areas by using Quartz, Feldspar and Lithics (QFL system) petrography, including quartz ratios, and palynology. The composition of the Agwu samples is similar to that of the Agbani samples. Lithologic description showed that some sections of the outcrops were ferruginized and calcareous. The sandstone samples from both locations are characterised by a high content of quartz group, ranging from 46 to 95%. The prevailing mineral from this group is calcite (31%–65%), which is indicative of a low degree of the litification of organic matter. Relatively low contents of feldspar are very minimal (not exceeding 9%) and rock fragments (not exceeding 8%) were also determined and palynomorphs were poor. The content of minerals is inferred from microscopic studies and is variable but generally high, varying from 35 to 75%, similar to that of other formations within the study area; it consists mostly of quartz, calcite and clay minerals. This input of mineral matter is probably related to periodic inundations of mangrove swamps which reflect the influence of oxidizing conditions during deposition. The age prediction of the palynomorphs was indeterminate.
The Fall of the Cosmic Mind: Cosmopsychism, the Satan Hypothesis, and Natural Evil
Authors: Cawdron Harvey
Published: January 2025

[Figure: see text]

Christian philosophers often use moral agents to explain the existence of evil. The fall of human beings can be used in explanations of moral evil, and some have posited the existence of angels to explain natural evil. The latter proposal, which has been labelled “the Satan hypothesis,” has faced substantial criticism. Here, I do not dismiss the Satan hypothesis, but present cosmopsychism, the idea that the universe is conscious, as an alternative way of using moral agents to explain natural evil for those skeptical of the Satan hypothesis. After introducing cosmopsychism into this debate and outlining how it can be used instead of the Satan hypothesis, I consider how it can provide an explanation of natural evil.
The Politics of the “New Evangelization” in the Post-Conciliar Catholic Church
Authors: Olkovich Nicholas
Published: January 2025

[Figure: see text]

Following rhetorical theorist Michael McGee, Benjamin Bennett-Carpenter and Michael J. McCallion contend that the term “new evangelization” may be understood as an “ideograph,” a symbolic reference point that galvanizes Catholics with different ideological sensibilities. This paper explores the “political” struggle to fix the meaning of this ideograph after the Second Vatican Council by distinguishing between two broad trends. The roots of the new evangelization as a nodal point in the post-conciliar era lie in the Latin American church's appropriation of Vatican II, beginning with the Conference of Latin American Bishops’ meeting at Medellin in 1968. This first strand of interpretation views justice as a constitutive dimension of the church's mission and tends to view evangelization in light of “liberation.” As articulated by Pope John Paul II, a second more mainstream or official strand views evangelization in principally spiritual terms and focuses on developing “new methods” for communicating doctrine and on fostering personal conversion to Christ within the secularized West. This approach tends to emphasize humankind's vertical relationship to God—as well as the uniqueness of Christ—and to view the poor as recipients of charitable work rather than as agents of transformation. Although Pope Francis’ program of ecclesial reform seeks to retrieve elements of the first strand, some proponents of the second strand have responded by rejecting Francis outright or by sanitizing his vision for their own purposes.
Looking and Listening for Lived Theologies of Truth and Reconciliation: Learning from a Diffuse Art Installation in the Anglican Diocese of Ottawa
Authors: Johnson Sarah Kathleen
Published: January 2025

[Figure: see text]

Christian complicity in colonialism and the need for truth telling and reconciliation with Indigenous peoples have been a central focus of academic theological research shared at the Canadian Theological Society in recent years. Many Canadian churches have offered official apologies and made formal commitments to right relations with Indigenous peoples. This paper considers the experience of “people in the pews.” Taking a diffuse visual art installation of white ceramic feathers as a starting point, it traces the contours of how local congregations in the Anglican Diocese of Ottawa are engaged with truth and reconciliation intellectually, emotionally, and actively. It names the need to bridge the gaps between academic theology and lived theology, and official church statements and everyday practices in congregations. It invites academic theologians to consider the questions: To whom are we listening? Who is listening to us?
The Philosophical Faith of Father Sergius Bulgakov
Authors: Gonotskaya Nadezhda Vasiljevna , Garadzha Nikita Vladimirovich
Published: January 2025

The Article examines the world view evolution of Father Sergius Bulgakov; namely, the stage of his radical reorientation to the problems of philosophical idealism and religious metaphysics. That world view is shaped by a tension between his mystical spiritual experiences described in his diary and jos attempts to externalize them as Christian politics. He articulates the relationship between philosophy and religion as an antinomy and therefore cannot be resolved only through rationalization. It demands for the orthodox consciousness the justification of philosophy in the light of religion. Overcoming the autonomy of reason is possible due to the rooting of philosophical reason in a specific religious experience. It is in the religious existential experience of the transcending subject that it is possible to go beyond the limits of empirical existence and overcome limitations of the secular autonomous reason. Thus, Bulgakov's views are largely in tune with European existential philosophy in interpreting the nature of philosophy as creativity rooted in the deepest, pre-rational foundations of human existence.

Matrimonial Property Rights: An Analytical and Comparative Study between Ugandan Civil Law and Islamic Law
Authors: Walusimbi Abdul Hafiz Musa
Published: January 2025

This research explores the trends in conceptualizing the matrimonial property in both statutory and Islamic laws in Uganda. Judges in both civil and Shariah courts have deliberated extensively on this concept, considering various socio-economic factors when determining what constitutes matrimonial property and the criteria for its distribution upon the dissolution of marriage. A qualitative study approach was employed to review both substantive and case laws, aiming to reveal the judges’ considerations regarding what constitutes matrimonial property and the basis for determining its distribution upon the dissolution of marriage. Data were collected through observation, in-depth study, and analysis of written materials reflecting the theoretical concepts used in this study. The study concludes that the concept of matrimonial property has developed gradually. Although secular and Islamic laws have taken different approaches to recognize it, both regimes acknowledge the woman’s contribution to matrimonial property. Consequently, they emphasize equity rather than equality in determining the shares upon the dissolution of marriage.
Identifying Gaps in Care Upon Discharge from Inpatient Psychiatry Settings to the Community
Authors: Kapty Connor
Published: January 2025

This literature review examines gaps in care within healthcare systems that negatively impact service users as they transition from inpatient psychiatric settings to community settings. Topics such as historical contexts, readmission rates, intrapersonal factors, and institutional limitations are taken into account to explain the complex relationship between community and inpatient psychiatric services and how they influence current gaps in care. Interventions to address these limitations are explored, which is aimed at examining different models of care and their subsequent impact on gaps in care. In these interventions, concepts such as continuity of care and therapeutic relationships are then proposed as vital factors when addressing gaps in care. Finally, this literature review suggests areas for future research to improve upon gaps in care.

Published: January 2025

Currently known from two valid species, Haplocanthosaurus priscus and H. delfsi, the Late Jurassic sauropod Haplocanthosaurus (Morrison Formation, Western United States) has often been described as an enigmatic sauropod taxon due to its unstable phylogenetic position and paucity of specimens. Here, we quantify the number of Haplocanthosaurus specimens known from the literature and in collections. Although most regions of the postcranial skeleton are known, the most commonly found elements of Haplocanthosaurus are vertebrae (dorsals and caudals) and tibiae. Our investigation identified twelve individuals of Haplocanthosaurus from ten localities across four states, Colorado, Utah, Montana (private specimen), and Wyoming, making Haplocanthosaurus spatially widespread in the central part of the Morrison Formation. The existence of twelve individuals across four states indicates this genus was widely distributed and more abundant than historically thought. Haplocanthosaurus has been characterized as a ‘primitive’ sauropod restricted to the lower half of the Morrison Formation, but the identification of Haplocanthosaurus in the Dry Mesa Dinosaur Quarry confirms that the genus was also present within the upper part of the Morrison Formation.

Spontaneous intracranial hypotension (SIH) is an increasingly diagnosed condition typically characterized by orthostatic headache and other symptoms caused by a decrease in cerebrospinal fluid (CSF) volume. The initial imaging work-up for patients with high pretest probability of SIH
begins with a brain MRI and total spine MRI. At our institution, if MRI demonstrates a spinal longitudinal extradural collection, dynamic CT myelography is performed to localize the CSF leak. Most spinal longitudinal extradural collections are ventral; thus, dynamic CT myelography is most
commonly performed with the patient in the prone position to elucidate the site of leak. If a lateral or dorsal extradural CSF collection is evident on MRI, lateral decubitus digital subtraction myelography or lateral decubitus CT myelography could be performed to identify less-common sites
of leak. If the MRI does not demonstrate an extradural CSF collection, then the patient undergoes a conventional myelogram. If the site of leak is not identified, this would typically be followed by bilateral lateral decubitus digital subtraction myelography. Treatment options are determined
on the basis of the ability to accurately locate the site and type of leak. This review presents several SIH cases to elucidate the imaging modalities for diagnosis, management algorithm, and therapeutic options.Learning Objectives: To understand the imaging findings, management algorithm,
and treatment options for spontaneous intracranial hypotension.

Spondyloarthritis is a group of diseases that cause inflammatory arthritis of the spine, sacroiliac joints, and peripheral joints. This group includes ankylosing spondylitis, psoriatic arthritis, arthritis associated with inflammatory bowel disease, reactive arthritis, undifferentiated
spondyloarthritis, and juvenile spondyloarthritis. Imaging of the sacroiliac joints and spine is crucial for the diagnosis of axial spondyloarthritis. Imaging of the sacroiliac joints is included in the classification criteria of axial spondyloarthritis. Radiographs have been used for decades
to image chronic changes in the sacroiliac joints and spine. CT is sensitive for demonstrating initial bone erosions and sclerosis. MR imaging is superior in detecting early inflammatory changes in bone and soft tissue. This review article summarizes features of various subtypes of spondyloarthropathies,
including their complications, and provides a brief review of potential differential diagnoses.Learning Objectives: To identify key imaging features of spondyloarthritis, including complications, and recognize top differential considerations.

Salt-freezing coupling is one of the main factors affecting the durability of recycled concrete. Investigating the chloride ion transport performance in recycled concrete containing recycled aggregate is essential to clarify the resistance of recycled concrete to chloride ion erosion due to the use of recycled aggregate produced from waste concrete. The objective of this paper is to investigate the migration behaviors and binding characteristics of chloride ions in recycled concrete, which were exposed to the salt-freezing coupling environment. The microstructure of the recycled concrete was conducted through scanning electron microscope (SEM), while the process of chloride ions migration was simulated by COMSOL software. The results indicated that the degree of recycled concrete, prepared by recycled coarse aggregate [RCA]and different particle size fly ash [NF], frost damage was higher in a 3 % NaCl solution compared to water. The contents of free chloride ions in recycled concrete subjected to freezing-thawing [F-T] cycle in water was minimally influenced by the NF content or the replacement rate of RCA. Under F-T conditions in a 3 % NaCl solution, increasing the NF content at the same replacement rate of RCA results in a decreasing-then-increasing trend in both the free chloride ion content and the chloride ion binding capacity in the concrete. Recycled concrete containing 15 % NF had a superior salt frost resistance compared to recycled concrete without NF or with ultrafine fly ash [SF]. With the replacement rates of RCA increasing, the contents of free chloride ions rose, the salt resistance of recycled concrete decreased. Using Fick’s second law, the chloride ion diffusion coefficient was calculated using MATLAB, and COMSOL software simulation accurately portrayed the diffusion state of free chloride ions in the recycled concrete.

Effectively designing molecular geometries is essential to advancing pharmaceutical innovations, a domain, which has experienced great attention through the success of generative models and, in particular, diffusion models. However, current molecular diffusion models are tailored towards a specific downstream task and lack adaptability. We introduce UniGuide, a framework for controlled geometric guidance of unconditional diffusion models that allows flexible conditioning during inference without the requirement of extra training or networks. We show how applications such as structure-based, fragment-based, and ligand-based drug design are formulated in the UniGuide framework and demonstrate on-par or superior performance compared to specialised models. Offering a more versatile approach, UniGuide has the potential to streamline the development of molecular generative models, allowing them to be readily used in diverse application scenarios.
Exploring QGP-Like Phenomena with Charmonia in p+p Collisions at √s=13 TeV

Published: January 2025

In ultra-relativistic collisions of nuclei at the Large Hadron Collider, the created QCD environment rapidly changes, leading to a non-adiabatic evolution of the quantum states involved. Considering this, we first examine the pre-equilibrium state of QCD matter and its effect on the initially produced charmonium using a temperature-independent Hamiltonian. As the QCD matter reaches local thermal equilibrium, this Hamiltonian transforms to its finite temperature counterpart. To model the pre-equilibrium stage, we use the bottom-up thermalization approach to determine the effective temperature of the QCD matter, followed by a Gubser-type expansion for the thermalized medium. Additionally, we consider collisional damping, gluonic dissociation, and regeneration mechanisms, which specifically modify the charmonium yield in the thermalized medium. Mainly, the gluonic dissociation and collisional damping cause a reduction in the yield conversely, regeneration through gluonic de-excitation enhances the yield of charmonium. Further, we explore the combined effects of these mechanisms on the collective yield of charmonium states with transverse momentum (\(p_T\)) and event multiplicity in the proton-proton collisions at \(\sqrt{s}=13\) TeV. Based on our findings, we contend that the combined effects of these mechanisms can serve as a robust probe for determining the possible existence of a thermalized QCD medium in such a small collision system.
Compositional Data Analysis for Modelling and Forecasting Mortality with the α-Transformation

Published: January 2025

Mortality forecasting is crucial for demographic planning and actuarial studies, particularly for predicting population ageing rates and future longevity risks. Traditional approaches largely rely on extrapolative methods, such as the Lee-Carter model and its variants which use mortality rates as inputs. In recent years, compositional data analysis (CoDA), which adheres to summability and non-negativity constraints, has gained increasing attention from researchers for its application in mortality forecasting. This study explores the use of the \(\alpha\)-transformation as an alternative to the commonly applied centered log-ratio (CLR) transformation for converting compositional data from the Aitchison simplex to unconstrained real space. The \(\alpha\)-transformation offers greater flexibility through the inclusion of the \(\alpha\)parameter, enabling better adaptation to the underlying data structure and handling of zero values, which are the limitations inherent to the CLR transformation. Using age-specific life table death counts for males and females in 31 selected European countries/regions from 1983 to 2018, the proposed method demonstrates comparable performance to the CLR transformation in most countries with improved forecast accuracy in some cases. These findings highlight the potential of the \(\alpha\)-transformation as a competitive alternative transformation technique for real-world mortality data within a non-functional CoDA framework.
