Published: February 2024

The study on the computational modelling of Nigeria’s crude oil prices during the Russia – Ukraine war was conducted to determine and select an appropriate model that best describes the functional behaviour of crude oil prices in Nigeria during the Russia – Ukraine war. The research data was the daily price of crude oil prices and the time under review collected from the Central Bank of Nigeria website, and spanned the period from February 24, 2022, to June 13, 2023. The total observations summed up to three hundred and eighteen days (318). Six models were estimated for the study namely; linear, quadratic, cubic, log-linear, linear-log, and log-log models. Nevertheless, the Log-linear Model, which had the values (S= 0.045; R2 = 67.6%; F = 660.29; p=.000), and the smallest accuracy measures (MAE = 0.030; MSE = 0.002; MAPE = 0.034), is adjudged as the best-fit model among the six built regression models. As a result, the Log-linear estimation has the most impact on the crude oil prices of Nigeria during the period of the Russia –Ukraine war under review. The study hereby recommends forecasting crude oil prices using the log-linear model.

Published: February 2024

Cuando se habla de métodos de crianza o formas de educar automáticamente se piensa en “maltrato”. Lo anterior es así derivado de las condiciones de adultocentrismo y violencia que permean dentro de la comunidad. Especialmente este artículo busca explicar el estilo de educación entre la "generación de cristal" y la "generación de cemento", visto lo anterior desde la ciencia de la Criminología. Como método, se realizó una revisión desde la literatura que permita, tener una posición del entendimiento de la crianza y su aplicación en las generaciones mencionadas. Como resultado no se pretende juzgar ni señalar cual método de crianza es el mejor, sino que opta por darle un enfoque criminológico que nos ayudará a observar desde otra perspectiva el por qué dichas generaciones están en constante conflicto. Y cómo conclusión, se consolida la posición de la Criminología, en el entendimiento de la repetición de conductas, especialmente visualizadas en los métodos de crianza.
Potential impacts of cable bacteria activity on hard-shelled benthic foraminifera: implications for their interpretation as bioindicators or paleoproxies

Published: February 2024

Abstract. Hard-shelled foraminifera are protists able to build a calcareous or agglutinated shell (called a “test”). Here we study the impact of sediment acidification on calcareous test preservation. For this study, sediment cores were sampled in the macrotidal Auray estuary located on the French Atlantic coast. Living and dead foraminifera were quantified until 5 cm depth and discriminated using the Cell-Tracker™ Green vital marker. The pH and oxygen profiles combined with quantitative polymerase chain reaction (qPCR) suggested that cable bacteria were most likely to cause the acidifying process. Cable bacteria (CB) are filamentous bacteria coupling sulfide oxidation to oxygen reduction over centimetre distances, generating a strong pH gradient within the first few centimetres of the sediment that could affect the microhabitats occupied by benthic foraminifera. On two different intertidal mudflats, volumetric filament densities have been estimated. They were comparable to those observed in the literature for coastal environments, with 7.4 ± 0.4 and 74.4 ± 5.0 m cm−3 per bulk sediment, respectively. Highly contrasting sediment acidification (from low to very intense) was described from 1.0 to 2.4 ΔpH. This seems to lead to various dissolution stages of the foraminiferal calcareous test from intact to fully dissolved tests revealing the organic lining. The dissolution scale is based on observations of living Ammonia spp. and Haynesina germanica specimens under a scanning electronic microscope. Furthermore, dead foraminiferal assemblages showed a strong calcareous test loss and an organic lining accumulation throughout depth under low pH, hampering the test preservation in deep sediment. These changes in both living and dead foraminiferal assemblages suggest that cable bacteria must be considered in ecological monitoring and historical studies using foraminifera as bioindicators and paleoenvironmental proxies.
UAV approaches for improved mapping of vegetation cover and estimation of carbon storage of small saltmarshes: examples from Loch Fleet, northeast Scotland

Published: February 2024

Abstract. Saltmarsh environments are recognised as key components of many biophysical and biochemical processes at the local and global scale. Accurately mapping these environments, and understanding how they are changing over time, is crucial for better understanding these systems. However, traditional surveying techniques are time-consuming and are inadequate for understanding how these dynamic systems may be changing temporally and spatially. The development of uncrewed aerial vehicle (UAV) technology presents an opportunity for efficiently mapping saltmarsh extent. Here we develop a methodology which combines field vegetation surveys with multispectral UAV data collected at two scales to estimate saltmarsh area and organic carbon storage at three saltmarshes in Loch Fleet (Scotland). We find that the Normalised Difference Vegetation Index (NDVI) values for surveyed saltmarsh vegetation communities, in combination with local tidal data, can be used to reliably estimate saltmarsh area. Using these area estimates, together with known plant community and soil organic carbon relationships, saltmarsh soil organic carbon storage is modelled. Based on our most reliable UAV-derived saltmarsh area estimates, we find that organic carbon storage is 15 %–20 % lower than previous area estimates would indicate. The methodology presented here potentially provides a cheap, affordable, and rapid method for saltmarsh mapping which could be implemented more widely to test and refine existing estimates of saltmarsh extent and is particularly well-suited to the mapping of small areas of saltmarsh environments.

Abstract. Land cover governs the biogeophysical and biogeochemical feedbacks between the land surface and atmosphere. Holocene vegetation-atmosphere interactions are of particular interest, both to understand the climate effects of intensifying human land use and as a possible explanation for the Holocene Conundrum, a widely studied mismatch between simulated and reconstructed temperatures. Progress has been limited by a lack of data-constrained, quantified, and consistently produced reconstructions of Holocene land cover change. As a contribution to the Past Global Changes (PAGES) LandCover6k Working Group, we present a new suite of land cover reconstructions with uncertainty for North America, based on a network of 1445 sedimentary pollen records and the REVEALS pollen-vegetation model coupled with a Bayesian spatial model. These spatially comprehensive land cover maps are then used to determine the pattern and magnitude of North American land cover changes at continental to regional scales. Early Holocene afforestation in North America was driven by rising temperatures and deglaciation, and this afforestation likely amplified early Holocene warming via the albedo effect. A continental-scale mid-Holocene peak in summergreen trees and shrubs (8.5 to 4 ka) is hypothesized to represent a positive and understudied feedback loop among insolation, temperature, and phenology seasonality. A last-millennium decrease in summergreen trees and shrubs with corresponding increases in open land likely was driven by a spatially varying combination of intensifying land use and neoglacial cooling. Land cover trends vary within and across regions, due to individualistic taxon-level responses to environmental change. Major species-level events, such as the mid-Holocene decline of eastern hemlock, may have altered regional climates. The substantial land-cover changes reconstructed here support the importance of biogeophysical vegetation feedbacks to Holocene climate dynamics. However, recent model experiments that invoke vegetation feedbacks to explain the Holocene Conundrum may have overestimated the land cover forcing by replacing Northern Hemisphere grasslands >30° N with forests; an ecosystem state that is not supported by these land cover reconstructions. These Holocene reconstructions for North America, along with similar LandCover6k products now available for other continents, serve the Earth system modeling community by providing better-constrained land cover scenarios and benchmarks for model evaluation, ultimately making it possible to better understand the regional- to global-scale processes driving Holocene land cover dynamics.

Published: February 2024

Abstract. Rapid expansion of mariculture during past decades has raised substantial concerns about impacts on the coastal environment, notably eutrophication. This study focuses on one of the world’s highest density mariculture sites, Sansha Bay, Fujian Province, China, featuring integrated multi-trophic aquaculture practices involving croaker, kelp and oyster, based on examination of nutrient distributions and releases. A two-endmembers-mixing model showed significant addition of dissolved inorganic nitrogen (DIN; 6.9 ± 4.1 μmol L-1) and phosphorus (DIP; 0.45 ± 0.29 μmol L-1) associated with mariculture activities in spring 2020. A mass balance model estimated an annual release of N and P from cage fish farming systems fed with mixed trash fish feed and formulated feed of (2.42 ± 0.15)×104 tons and (5.33 ± 0.37)×103 tons, respectively. Of the total feed input, 52.8 ± 4.7 % of DIN and 33.0 ± 3.7 % of DIP were released into seawater, values much higher than the riverine input and exchange with offshore coastal waters. A co-culture strategy involving kelp and oyster production in 2020 removed (1.08 ± 0.01)×103 tons of N and (1.56 ± 0.08) ×102 tons of P, respectively. Therefore, adjusting feed strategies and improving feed conversion rates could alleviate eutrophication caused by mariculture expansion in this ecosystem.
New estimates of sulfate diffusion rates in the EPICA Dome C ice core
Authors: Rhodes Rachael H. , Bollet-Quivogne Yvan , Barnes Piers R. F. , Severi Mirko , Wolff Eric W.
Published: February 2024

Abstract. To extract climatically relevant chemical signals from the deepest, oldest Antarctic ice, we must first understand the degree to which chemical ions diffuse within solid ice. Volcanic sulfate peaks are the ideal target for such an investigation because they are high amplitude, short duration (~3 years) events with a quasi-uniform structure. Here we present analysis of the EPICA Dome C sulfate record over the last 450 kyr. We identify volcanic peaks and isolate them from the non-sea salt sulfate background to reveal the effects of diffusion: amplitude damping and broadening of peaks in the time domain with increasing depth/age. Sulfate peak shape is also altered by the thinning of ice layers with depth that results from ice flow. Both processes must be simulated to derive effective diffusion rates. This is achieved by running a forward model to diffuse idealised sulfate peaks at different rates while also accounting for ice thinning. Our simulations suggest a median effective diffusion rate of sulfate ions of 2.4 ± 1.7 x 10-7 m2 yr-1 in the Holocene ice, slightly faster than suggested by previous work. The effective diffusion rate observed in deeper ice is significantly lower, and the Holocene ice shows the highest rate of the last 450 kyr. Beyond the Holocene, there is no systematic difference between the effective diffusion rates of glacial and interglacial periods despite variations in soluble ions concentrations, dust loading and ice grain radii. Effective diffusion rates for 40 to 200 ka are relatively constant, on the order of 1 x 10-8 m2 yr-1. Our results suggests that the diffusion of sulfate ions within volcanic peaks is relatively fast initially, perhaps through the inter-connected vein network, but slows significantly after 40 kyr. In the absence of clear evidence for a controlling environmental factor on sulfate diffusivity with depth/age, we hypothesize that the rapid decrease in diffusion rate from the time of deposition to ice of 50 ka age may be due to a switch in the mechanism of diffusion resulting from the changing location of sulfate ions within the ice microstructure.
Mechanisms and intraseasonal variability of the South Vietnam Upwelling, South China Sea: role of circulation, tides and rivers
Authors: Herrmann Marine , To Duy Thai
Published: February 2024

Abstract. Summer monsoon southwest wind induces the South Vietnam Upwelling (SVU) over four main areas along the southern and central Vietnamese coast: offshore the Mekong shelf (MKU), along the Southern and Northern coasts (SCU and NCU) and offshore (OFU). Previous studies have highlighted the roles of wind and Ocean Intrinsic Variability (OIV) in the SVU intraseasonal to interannual variability. The present study complements these results by examining the influence of tides and river discharges and investigating the physical mechanisms involved in MKU functioning. MKU is driven by non chaotic processes, explaining its negligible intrinsic variability. It is triggered first by the interactions of currents over a marked topography. The surface convergence of currents over the southwestern slope of the Mekong shelf induces a downwelling of the warm northeastward alongshore current. It flows over the shelf and encounters a cold northwestward bottom current when reaching the northeastern slope. The associated bottom convergence and surface divergence lead to an upwelling of cold water which is entrained further north by the surface alongshore current. Tides and rivers do not modify the chronology of upwelling for the four areas. Tides do not significantly influence OFU and NCU intensity. They strengthen the circulation-topography-induced MKU through two processes. First, tidal currents weaken the current over the shallow coastal shelf by enhancing the bottom friction. This increases the horizontal velocity gradient hence the resulting surface convergence and divergence and the associated downwelling and upwelling. Second, they reinforce the surface cooling upstream and downstream the shelf through lateral and vertical tidal mixing. This tidal reinforcement explains 72 % of MKU intensity on average over the summer, and is partly transmitted to SCU through advection. River discharges do not significantly influence OFU, NCU and SCU intensity. Mekong waters slightly weaken MKU (by 9 % on the annual average) by strengthening the stratification.
Co- and postseismic subaquatic evidence for prehistoric fault activity near Coyhaique, Aysén Region, Chile

Published: February 2024

Abstract. Chilean Patagonia is confronted with several geohazards due to its tectonic setting, i.e., the presence of a subduction zone and numerous fault zones (e.g. the Liquiñe-Ofqui Fault Zone). This region has therefore been the subject of numerous paleoseismological studies. However, this study reveals that the seismic hazard is not limited to these large tectonic structures by identifying past fault activity near Coyhaique in the Aysén Region. Mass wasting deposits in Lago Pollux, a lake located ca. 15 km SW of this region’s capital, were identified through analysis of reflection-seismic data and was linked to a simultaneous event recorded in nearby Lago Castor. Furthermore, a coeval ~50 year-long catchment response was identified in Aysén Fjord based on the multiproxy analysis of a portion of a sediment core. Assuming that this widely recognized event was triggered by an earthquake, ground-motion modelling was applied to derive the most likely magnitude and source fault. The model showed that an earthquake rupture along a local fault, in the vicinity of Lago Pollux and Lago Castor, with a magnitude of 5.6–6.8, is the most likely scenario.
Impacts of updated reaction kinetics on the global GEOS-Chem simulation of atmospheric chemistry
Authors: Bates Kelvin H. , Evans Mathew J. , Henderson Barron H. , Jacob Daniel J.
Published: February 2024

Abstract. We updated the chemical mechanism of the GEOS-Chem global 3-D model of atmospheric chemistry to include new recommendations from the NASA Jet Propulsion Laboratory (JPL) chemical kinetics Data Evaluation 19-5 and from the International Union of Pure and Applied Chemistry (IUPAC) and to balance carbon and nitrogen. We examined the impact of these updates on the GEOS-Chem version 14.0.1 simulation. Notable changes include 11 updates to reactions of reactive nitrogen species, resulting in a 7 % net increase in the stratospheric NOx (NO + NO2) burden; an updated CO + OH rate formula leading to a 2.7 % reduction in total tropospheric CO; adjustments to the rate coefficient and branching ratios of propane + OH, leading to reduced tropospheric propane (−17 %) and increased acetone (+3.5 %) burdens; a 41 % increase in the tropospheric burden of peroxyacetic acid due to a decrease in the rate coefficient for its reaction with OH, further contributing to reductions in peroxyacetyl nitrate (PAN; −3.8 %) and acetic acid (−3.4 %); and a number of minor adjustments to halogen radical cycling. Changes to the global tropospheric burdens of other species include −0.7 % for ozone, +0.3 % for OH (−0.4 % for methane lifetime against oxidation by tropospheric OH), +0.8 % for formaldehyde, and −1.7 % for NOx. The updated mechanism reflects the current state of the science, including complex chemical dependencies of key atmospheric species on temperature, pressure, and concentrations of other compounds. The improved conservation of carbon and nitrogen will facilitate future studies of their overall atmospheric budgets.
Changing snow water storage in natural snow reservoirs
Authors: Aragon Christina Marie , Hill David F.
Published: February 2024

Abstract. This work introduces a novel snow metric, snow water storage (SwS), defined as the integrated area under the snow water equivalent (SWE) curve (units: length-time, e.g., m d). Unlike other widely used snow metrics that capture snow variables at a single point in time (e.g., maximum SWE) or describe temporal snow characteristics (e.g., length of snow season), SwS is applicable at numerous spatial and temporal scales. This flexibility in the SwS metric enables us to characterize the inherent reservoir function of snowpacks and quantify how this function has changed in recent decades. In this research, changes in the SwS metric are evaluated at point, gridded and aggregated scales across the conterminous United States (hereafter US), with a particular focus on 16 mountainous Environmental Protection Agency (EPA) Level III Ecoregions (ER3s). These ER3s account for 72 % of the annual SwS (SwSA) in the US, despite these ER3s only covering 16 % of the US land area. Since 1982, spatially variable changes in SwSA have been observed across the US with notable decreasing SwSA trends in the western US and in the 16 mountainous ER3s. All mountainous ER3 (except for the Northeastern Highlands in New England) exhibit decreasing trends in SwSA resulting in a 22 % overall decline in SwSA across mountainous ER3s. The peak monthly SwS (SwSM) occurs in March at all spatial scales, while the greatest percentage loss of SwSM occurs early in the snow season, particularly in November. Unsurprisingly, the highest elevations contribute most to SwSA in all mountain ranges, but the specific elevations that have experienced loss or gain in SwSA over the 39-year study period vary between mountain ranges. Comparisons of SwS with other snow metrics underscore the utility of SwS, providing insights into the natural reservoir function of snowpacks, irrespective of SWE curve variability or type (e.g., ephemeral, mountain, permanent). As we anticipate a future marked by increased climate variability and greater variability in mountain snowpacks, the spatial and temporal flexibility of snow metrics such as SwS may become increasingly valuable for monitoring and predicting snow water resources.

Authors: E. V. Thomas  , Uttam Kumar
Published: February 2024

Self-propelled rice transplanting machines were commercially produced and used in Japan. Countries like Thailand, Bangladesh, India, Sri Lanka and Pakistan are still carrying out researches for development of mechanical rice transplanter suitable for their countries. Most power-operated transplanters use two-dimensional four-bar linkage mechanism in their planting unit with the transplanting finger an extension of the coupler link. Design of power-operated planting mechanisms involves a process of analytical synthesis to analyse the path of motion and velocity of finger at the point of picking of the seedling and at the point of planting. Link dimensions are modified until a suitable mechanism is obtained. This paper summarizes some of the planting designs for development of rice transplanters.

Foi objetivo deste estudo revisar a literatura sobre o ensino da postura corporal nos Instrumentos de Cordas Friccionadas (ICF) na Educação a Distância (EaD). O corpus documental teve 17 estudos analisados com base na Análise Temática de Conteúdo. Os principais desafios do ensino da postura de ICF na EaD são a manutenção da relação afetiva do aluno com o conhecimento, adaptar as aulas presenciais à EaD, dispositivos sem os recursos mínimos para a EaD, falta de acesso à internet e falta de domínio dos dispositivos e softwares. As estratégias para dirimir as dificuldades são diálogos para motivar os alunos, gravar e enviar aulas e “áudio guias” previamente aos encontros síncronos, gravar o estudo dos alunos e dar feedbacks, ministrar aulas de musicalização e construir instrumentos alternativos para a falta de ICF. Considerando a natureza processual da postura, o Ensino Híbrido pode contribuir no ensino dos ICF.
The genesis of opera singing in Ukrainian chamber vocal music
Authors: Kadanceva Natalia , Kablova Tetiana , Liu Yeyu
Published: February 2024

The article considers the specifics of chamber and vocal genres in Ukrainian music culture. Genre evolution of Ukrainian chamber and vocal music covers the XVIII-XX centuries. and consists of 3 stages: from Cantus and song-romance music of the XVIII-early XIX centuries, then romance (mid-XIX century) of strophic and three-part form, to pan-European parallels in the form of lyrical vocal miniature through type or recitative monologue, including touches of arioso expressiveness. The Ukrainian Cantus as a genesis for creation of chamber vocal culture is analyzed. It is determined that the Ukrainian Cantus becomes the basis of the national romance line in the chamber sphere, which extremely actively covered the lyrical array of singing and in the chamber variety, anticipating the aria in the Ukrainian urban-salon sphere. It is noted that the genesis and evolution of Ukrainian romance in the links with folklore and cult tradition, which determined the place of chamber vocal music in Ukrainian opera.

Este artigo procura demonstrar como demais elementos musicais, muitas vezes negligenciados, apontam para um incremento na expressividade e constituição estética da música brasileira na época da Tropicália. Para tanto nos valemos do conceito de Serialismo Tropical (XXXX, 2020) que denota uma apropriação específica de técnicas serialistas européias. Como exemplo apresentaremos uma detalhada análise que pretende explicitar os elementos musicais que corroboram com nossa hipótese a partir da canção Let's Play That (1972) do artista Jards Macalé. Esperamos demonstrar como diversos elementos musicais se integram para formar um "programa de arte" (Pareyson, 2001) específico que  representa esteticamente uma expressão contra a opressão generalizada vigente na época.
Francisco Xavier Baptista’s keyboard works
Authors: Nejmeddine Mafalda S.
Published: February 2024

The Portuguese composer Francisco Xavier Baptista (1741-1797) wrote sixteen keyboard sonatas, two of which are preserved under the name of Francisco Xavier Bachixa. From an analysis based on the Sonata Theory by Hepokoski and Darcy, this study identifies the characteristics of Baptista’s sonatas, as well as his sonata model: a cycle of two movements that ends with a minuet, this being representative of a clear formal transformation. Furthermore, the comparison of the single-movement sonatas indicated by the name Bachixa shows that these were the last works written by the composer and reveals a new formal and stylistic approach to the composition of the Portuguese keyboard sonata in the late 18th century.

Desde la metodología analítica, deductiva y conceptual  se revisa el uso de modos en la Grecia clásica, conceptos modales medievales, nacionalistas y del siglo XX, así como su empleo en las músicas populares latinoamericanas y el jazz. También se considera brevemente la construcción modal en culturas como las africanas y asiáticas, cuyas estructuras interválicas no corresponden a las teóricamente establecidas en occidente. Finalmente se hacen aproximaciones sobre el funcionamiento modal en prácticas patrimoniales en el Ecuador y en objetos arqueológicos encontrados, con el propósito de tener como resultado una amplia gama de posibilidades de reflexión antropológica sobre la música modal y de creación musical contemporánea, basadas en la investigación etnográfica e histórica.

Background/Aims: Nonalcoholic fatty liver disease (NAFLD) is a common disease with severe inflammatory processes associated with numerous gastrointestinal diseases, such as inflammatory bowel disease (IBD). Therefore, we investigated the relationship between NAFLD and IBD and the possible risk factors associated with the diagnosis of IBD. Methods: This longitudinal nationwide cohort study investigated the risk of IBD in patients with NAFLD alone. General characteristics, comorbidities, and incidence of IBD were also compared. Results: Patients diagnosed with NAFLD had a significant risk of developing IBD compared to control individuals, who were associated with a 2.245-fold risk of the diagnosis of IBD and a 2.260- and 2.231-fold of increased diagnosis of ulcerative colitis and Crohn’s disease, respectively (P< 0.001). The cumulative risk of IBD increased annually during the follow-up of patients with NAFLD (P< 0.001). Conclusions: Our results emphasize that NAFLD significantly impacts its incidence in patients with NAFLD. If patients with NAFLD present with risk factors, such as diabetes mellitus and dyslipidemia, these conditions should be properly treated with regular follow-ups. Furthermore, we believe that these causes may be associated with the second peak of IBD.

The Giant African land snail, Achatina achatina, is an invasive species recognized for being a serious agricultural pest and vector for diverse parasites that cause diseases in humans. This study assessed the prevalence of parasites harboured by the snails collected from bushes in the Otuoke community of Bayelsa State, Nigeria. The snail samples were collected and transported to the laboratory for examination using wet mouth preparation and teasing methods. Subsequently, they were classified by size into small, medium and large. The body organs were individually teased and examined under the microscope. 122 snail samples (32 small, 54 medium, 36 large) were randomly collected for this study and examined for the presence of eggs or larvae of parasites, out of which 108 (88.5%) were infected. The larvae of only two species of parasites, Angiostrongylus cantonensis (90.1%) and Strongyloides stercoralis (9.9%)) were recovered from the infected snails, with A. cantonensis being most prevalent, 737 (90.1%). The parasites were most prevalent in the medium snails (42.6%), followed by the small size (23.8%) and then, the large size snails with the least prevalence of infection. The slime, intestine and stomach were infected, with the parasites being more in the slime (88.5%) than any other body parts. Since the Giant African land snail serves as an intermediate host for several parasites, a thorough understanding of the snail parasites' lifecycles and modes of transmission to humans is important, for human health and welfare, sustainable snail farming, and for maintenance of snail biodiversity.

This study sought to assess the patterns of substance abuse among healthcare professionals in selected hospitals in Asaba, Delta State. The work was guided by six research objectives and three hypotheses. Relevant literature was reviewed under the study’s objectives and research questions. Data was acquired using a research questionnaire distributed to 400 healthcare professionals selected from three different hospitals in Asaba. 360 of the respondents properly filled out and returned their questionnaires, which were used for data analysis. Data analysis employed descriptive and inferential statistics. The results, presented in tables, displayed frequencies and percentage distributions. The findings indicated that the majority of respondents (78.1%) believed that alcohol was the most commonly abused substance among healthcare professionals, followed by tobacco (67.5%). The study also found that the reasons healthcare professionals engage in substance abuse include: easy access (62.5%), excessive workloads (56.9%), and stress (51.7%). The results also revealed that age and marital status influenced substance abuse among healthcare professionals, as indicated by 48.1% of respondents. Male healthcare professionals were more likely to abuse substances than their female counterparts, as submitted by 62.5% of respondents. The study also revealed that substance abuse among healthcare professionals significantly impacted their judgment in the hospital, as strongly agreed upon by 51.7% of participants. The hypotheses tested in the study confirmed significant associations between age and substance abuse, gender and substance abuse, as well as marital status and substance abuse among healthcare professionals in hospitals in Asaba, Delta State. Based on the study’s findings, it is recommended that the government organise community awareness programs aimed at educating healthcare professionals and society as a whole about the detrimental effects of substance abuse.

Aim: The aim of the study was to compare the anti-microbial efficacy against oral pathogens, anti-inflammatory, and antioxidant activity of ethanolic and aqueous extract of Erythrina variegata. Materials and Methods: Agar well diffusion method was used to assess the antimicrobial activity of ethanolic and aqueous extract of Erythrina variegata against Enterococcus faecalis and Candida albicans at 25µL, 50µL, and 100µL by measuring the zone of inhibition. Anti-inflammatory activity was assessed using the Bovine Serum Albumin (BSA) assay and anti –oxidant activity was assessed using the DPPH assay. Results: Enterococcus faecalis and Candida albicans were found to be less sensitive to both, aqueous and ethanolic extract of Erythrina variegate. The anti-inflammatory activity of ethanolic extract of Erythrina variegata was higher than the aqueous extract at lower concentrations. Anti-oxidant activity of aqueous extract of Erythrina variegata was higher than the ethanolic extract and standard values at all concentrations. Conclusion: Findings from this study suggest that both, aqueous and ethanolic extracts of Erythrina variegata leaves have the potential anti-inflammatory and anti-oxidant activity and can be used as an alternative to commercially available drugs. However, further research needs to be done on the antimicrobial activity against oral pathogens of the plant.
