New perspectives on morphosyntactic variation in African youth language practices
Authors: Gibson Hannah , Hollington Andrea , Nassenstein Nico , Reilly Colin 
Published: October 2024

Abstract
Recent years have seen an increase in scholarly attention paid to youth language practices in Africa, with studies examining a range of linguistic phenomena. A parallel development has seen the emergence of work studying morphosyntactic microvariation in Bantu languages, with a view to better understanding structural variation in closely related languages or varieties. This special collection brings together those working in the fields of youth language practices and morphosyntactic variation in Bantu, with a view to exploring the synergies in these areas, as well as moving this domain of inquiry forward. The contributions are united by the authors’ commitment to addressing specific morphosyntactic phenomena which may have otherwise gone unnoticed, or which are less documented in the existing literature – in particular, in the scholarship on the respective base language or dominant language. We hope that the collection of papers both contributes to this body of work and inspires others to take up some of these issues in future research.

Conclusiones El fenotipo hipertensión-obesidad abdominal es una opción sencilla, útil para identificar a personas con disglucemia y resistencia a la insulina.
Maternal Health Financing and Postpartum Detentions: Political Will as an Underlying Determinant For Respectful Maternity Care in Kenya
Authors: Odada Kerigo 
Published: October 2024

Maternal health financing is one of the critical aspects of health financing that the Kenyan government has focused on from as early as 1965. Over the years, through several policy initiatives, the government has demonstrated its commitment to providing free access to maternal healthcare services, especially for the poor, although with limited success. Like many other government projects, the implementation of free maternity care initiatives has been full of political, technical and financial challenges, which, as of 2024, have taken a turn for the worst with the government’s 2024/25 national budget slashing the budgetary allocation for free maternal health care by half. Presently, the maternal healthcare financing model either prevents women from accessing maternity care services due to the high cost of care or places them at risk of postpartum detention and abuse in hospitals. This article, through a qualitative methodological approach involving the analysis of secondary data collected from various sources available via desktop research, therefore demonstrates that legal recognition of rights without equitable health financing plans and political will does not address the challenges associated with inequitable access to respectful maternity care.

Provenance of Paleogene Strata at Slim Buttes, South Dakota: Implications for post-Laramide Evolution of Western Laurentia
Authors: Moll Joseph , Maher Harmon , Malone Joshua , Malone David , Craddock John 
Published: October 2024

Slim Buttes is a 30 km long by 10 km wide set of buttes containing Paleogene strata in northwest South Dakota. At Reva Gap in northern Slim Buttes, Eocene-Oligocene terrestrial strata of Chadron and Brule Formations of the White River Group unconformably overlie the Paleocene Fort Union Formation. An angular unconformity separates the White River Group from overlying Oligocene and Miocene strata of the Arikaree Group. Using detrital zircon U-Pb ages, we determine the provenance of these rocks as part of a broader synthesis of post-Laramide sedimentation in the Rocky Mountains and western Great Plains. The Chadron Formation age spectrum is dominated by Cretaceous and Proterozoic grains that are interpreted to be locally recycled from the underlying Cretaceous and Paleocene strata. The Brule Formation has a maximum depositional age of ~34 Ma; Paleogene zircons dominate the age spectrum, and a wide variety of older zircons are also present. The Oligocene zircons are interpreted to have been sourced from volcanic systems in the Great Basin to the southwest, while the subsequent proportions of the zircons were derived from a variety of source areas in the Nevadaplano and Rocky Mountain areas to the southwest. Sparse amounts of Archean zircons are thought to represent the burial of Laramide uplifts throughout Wyoming at the time of Brule deposition, making for a regional paleotopography with little relief across the western interior of the United States. The Miocene-age Arikaree Group sand has a maximum depositional age of ~26 Ma and a multimodal detrital zircon age spectrum. The Arikaree Group provenance likely represents continued sourcing in the Great Basin volcanic systems and Nevadaplano, the beginnings of the re-exhumation of Laramide basement uplifts, and subsequent sediment evacuation out of the western interior and into the Gulf of Mexico to the southeast. Our findings indicate that the transport process and detrital zircon provenance signatures of these strata are decoupled, and each have their own independent evolution. The volcanic signature is primarily transported via aeolian processes (i.e. volcanic ash), and the recycled detrital zircon signature is primarily transported via fluvial processes.

Physiochemical and Mechanical Aspects of CO2 Storage in Deep Saline Aquifers: An Experimental Study
Authors: Ahmed Musa E. M. , Paker Deniz M. , Dindoruk Birol , Drylie Stephen 
Published: October 2024

Abstract
The storage of carbon dioxide (CO2) in subsurface reservoirs is an important option for mitigating anthropogenic greenhouse gas emissions and addressing the global challenge of climate change. However, implementing carbon capture and storage (CCS) technologies involves many complex and coupled processes requiring thorough investigation. These complexities arise from the complex interactions in the subsurface between geological, hydrological, geochemical, and geomechanical factors. Understanding and managing these multifaceted processes are essential for successful and safe deployment of CCS as a vital component of sustainable energy and environment strategies. This experimental study investigates the multi-threaded impact of CO2 storage within a sandstone reservoir.
We employ a comprehensive approach, integrating batch reactor, X-ray diffraction (XRD), inductively coupled plasma (ICP) analysis, acoustic measurements, and routine core analysis (RCA) to examine the physiochemical and mechanical response of the selected rock-fluid system. We measured the changes in Berea sandstone before and after 30 days of CO2 storage at selected reservoir conditions (1500 psi and 150°F). Cores and effluent fluids collected at the end of the storage period were analyzed to measure the changes in the critical geochemical and geomechanical parameters (i.e., rock porosity, permeability, mineralogy, mechanical properties) between post-storage and pre-storage. The novelty of this work lies in its comprehensive and multi-dimensional approach to studying CO2 storage in sandstone reservoirs (i.e., saline aquifers), providing valuable insights for the advancement of sustainable carbon capture and storage solutions.
The results reveal significant alterations in mineralogy, fluid chemistry, and geomechanical stability. Notably, XRD analysis indicated the formation of new mineral phases, such as halite, and the dissolution of carbonate minerals. ICP analysis showed substantial increases in bicarbonate and sulfate ion concentrations, indicating intense mineral dissolution and ion exchange processes. RCA data demonstrated a decrease in porosity by 0.5% and permeability by 24.0%, attributed to mineral precipitation within pore spaces. Acoustic measurements highlighted changes in geomechanical stability, with alterations in acoustic velocities reflecting changes in rock stiffness and density
This research advances our quantitative understanding of the complex interactions within sandstone reservoirs during CO2 storage at the selected timescale that can capture the first order changes in the rock-fluid system. It provides critical information on kinetics, petrophysical properties and geomechanics, contributing essential knowledge for safe and efficient carbon capture and storage (CCS) technology implementation.

Abstract

Background: Acute heart failure is the gradual or rapid change of heart failure signs and symptoms, which poses a unique diagnostic and management challenge, requiring urgent therapy. It is responsible for nearly one million hospitalizations each year globally with rising rates. Despite therapeutic advances, it is associated with poor prognosis. Therefore, his study aimed to assess in-hospital mortality and its associated factors among adult acute heart failure patients in a tertiary hospital, Harar, Eastern Ethiopia.
Methods: A hospital based retrospective cross-sectional study was employed among 454 adult acute heart failure patients treated in the medical ward of Haramaya University Hiwot Fana Comprehensive Specialized Hospital from June 01, 2016 to May 31, 2021. Data was collected using structured data abstraction format from July 15 to August 14, 2021. Collected data was entered to Epi-Data version 3.1, exported to, and analyzed using statistical package for social science (SPSS) version 21.0. Bivariate and multivariate logistic regression was used to identify factors associated with in-hospital mortality.
Results: A total of 454 acute heart failure patient’s medical records were reviewed. More than half, 282(62.1%) of patients were females. The median age of patients was 45 years (±28 IQR). In-hospital mortality was 18.9% and it was more prevalent in the first week of admission, 61(70.9%). Sex (female) (adjusted odds ratio (AOR) = 2.83, P = 0.001)), having smoking history (AOR = 2.51, P = 0.031), generalized body swelling (AOR = 2.67, P = 0.001), hypotension (AOR = 4.56, P = 0.001), and tachycardia (AOR = 4.57, P = 0.000) were factors associated with in-hospital mortality.
Conclusions: In-hospital mortality is found to be very high among acute heart failure adult patients. Therefore, dedicated programs need to be developed to reduce mortality from acute heart failure and further prospective study should be conducted to investigate the problem in-depth.

Abstract

The presence and extent of metastatic disease in axillary lymph nodes (ALNs) in the setting of breast cancer (BC) are important factors for staging and therapy planning. The purpose of this study was to perform a multiparametric sonographic evaluation of ALNs to better differentiate between benign and metastatic nodes. Ninety-nine patients (mean age 54.1 y) with 103 BCs were included in this study, and 103 ALNs were examined sonographically. B-mode parameters, such as size in two dimensions, shape, cortical thickness and capsule outline, were obtained, followed by vascularity assessment via colour Doppler and microflow imaging and stiffness evaluation via shear wave elastography. Postoperative histopathological evaluation was the reference standard. In the statistical analysis, logistic regression and ROC analyses were conducted to search for feature patterns of both types of ALNs to evaluate the prediction qualities of the analysed variables and their combinations. For a cortex larger than 3 mm, without a circumscribed margin of the LN capsule and SWE (E max > 26 kPa), the AUC was 0.823. Multiparametric assessment, which combined conventional US, quantitative SWE and vascularity analysis, was superior to the single-parameter approach in the evaluation of ALNs.

Published: October 2024

Abstract

This research was conducted to determine the effect of bacterial strains isolated from different sources on the development of melon plants. Plant growth promotion mechanisms such as calcium, potassium and phosphorus solubilization, nitrogen fixation, phytohormone, siderophore and ACC-deaminase production and their growth at different pH and salt concentrations were determined. In order to determine the effect of bacterial strains on plant growth, field trials were established according to the randomized blocks experimental design with three replicates and carried out with two years of repetition. In the experiment established for this purpose, 11 different applications [IT 22 (Bacillus safensis), IT 22 + Fertilizer, IT 63 (Acinetobacter calcoaceticus), IT 63 + Fertilizer, IT 93 (Acinetobacter calcoaceticus), IT 93 + Fertilizer, IT 115 (Serratia rubidaea), IT 115 + Fertilizer and control (fertilizer only)] were included. In terms of all parameters examined, the best result was obtained from the Mix + Fertilizer application, while only the highest value of WSDM (9.9%) was measured in the IT 93 + Fertilizer application. The results of the study show that fertilizer-free IT 93 and Mix applications provide higher melon yield than fertilizer, suggesting that bacterial single or mixed applications can be used as a very effective method to reduce the use of chemical fertilizers. In addition, higher fruit yield per decare was obtained in the blocks where bacteria and fertilizer were applied together, except for IT 115 + Fertilizer application, compared to the control group. This result was an indication that a significant reduction in chemical use will be achieved with the inclusion of the determined bacterial strains in fertilization programs.

Abstract

Bioremediation using plants and microorganisms effectively mitigates heavy metal soil contamination and improves soil conditions. Phytoremediation with leguminous plants and rhizobacteria enhances metal bioavailability and promotes plant growth. This study evaluates microbial community structure in soils with varying concentrations of tailings from the Fundão Dam disaster in Mariana, MG, Brazil. Microbial diversity was measured by fluorescent in situ hybridization in treatments with different tailings concentrations and in the presence of Leucaena leucocephala. Higher tailings proportions reduced bacterial densities, with pure ore tailings (T100%) showing the lowest bacteria percentage. However, after 14 months of leucaena cultivation, this treatment had the highest number of prokaryotes. The presence of leucaena plants modified the densities of Bacteroidetes and the Pseudomonas genus. Experimentation time influenced the densities of Actinobacteria, Acidobacteria, and Firmicutes. The interaction between legume presence and sampling time altered the density of Proteobacteria and Gallionella ferruginea. The results show that iron ore tailings impact the microbial community in the plant rhizosphere, offering insights for bioremediation strategies to restore soil quality in mining-affected areas.

Published: October 2024

Abstract

Aim: This study analyzed the associations between various clinical and imaging parameters with overall survival (OS) and recurrence-free survival (RFS) in vulvar cancer.
Materials and Methods: A total of 45 patients diagnosed with vulva tumors were retrospectively analyzed. Data were extracted from medical records, including age, tumor size, ADC, SUVmax, and metastases identified through MRI and PET. Survival outcomes were estimated using Kaplan-Meier methods, while associations between variables and survival were assessed using Cox regression. Optimal cut-points for continuous variables were determined using maximally selected rank statistics.
Results: The median OS was 9.97 years, with age, tumor size, and SUVmax measurements significantly influencing OS. Optimal cut-points at 4-year survival were established for age 65.9 years, the largest axial dimension of 5.50 cm, craniocaudal dimension of 4.7 cm, SUVmax of 22.0, and ADC value of 1.026 x10-3 mm2/s. Patients with measurements above these cut points typically had worse survival outcomes.
Conclusion: Age, Size, and SUVmax predict survival in patients with vulvar cancer.
