Affordability, Accessibility, and Utilization of Antimalarial Drugs in Nigeria’s Niger Delta: Emphasis on Artemisinin Combination Therapy (ACT)
Authors: Odion Prisca O. , Suleiman Ismail A.
Published: November 2024

Background: Despite recommendations for artemisinin combination therapies as first-line malaria treatment, chloroquine, and other monotherapies continue to be widely used in Nigeria, primarily due to issues related to availability and affordability.
Objectives: This study aimed to assess the affordability and availability of antimalarial treatments in the Niger Delta, evaluating key factors influencing their use.
Methods: Structured questionnaires focused on affordability and availability were distributed across six local government areas in Delta and Bayelsa States, targeting individuals and various healthcare facilities, including pharmacies, medicine stores, and hospitals. Data were analyzed using SPSS.
Results: Among the 582 respondents, 62.9% (366) were aware of ACTs; however, only 24.9% considered them affordable. Higher education attainment was positively correlated with affordability and preference for ACTs, with those holding tertiary education more likely to afford and prefer ACTs. The overall availability of ACTs was moderate, at 63.1%, but their presence in government-owned primary health centers was notably limited. As a result, there remains a strong preference for monotherapy, with only 28.9% of respondents choosing ACTs despite WHO recommendations.
Conclusion: While ACTs are moderately available, their cost limits accessibility, favoring monotherapy use over the recommended ACT treatments. Enhanced affordability and availability of ACTs are essential to improving adherence to WHO malaria treatment guidelines in the Niger Delta region.

Published: November 2024

The special focus of this paper is to discuss a likely intersection of machine learning, artificial intelligence (AI) technology, and game theory, pointing at the importance of this synthesis both in mathematics and engineering. As these domains develop various means of addressing decision-making problems become more and more sophisticated and can be used in different areas such as economics, security, and social sciences. We will also address selected game-theoretic issues including the concept of decision making in terms of Nash equilibria or in the distinction of games as being cooperative or non-cooperative and how they work in synergy with machine learning approaches bringing in reinforcements and deep learning to leverage forecasting and strategizing. The paper makes references to problem-oriented branches of studies such as autonomous systems or market strategies stressing the importance of the novel direction for further studies. Within the scope of machine learning and game theory the goal is to implement better complex models which utilize real world intricacies for enhancing decision making within a populated agent environment.

Published: November 2024

Aims: Management of cardiac disease in aeromedical expertise can be challenging for asymptomatic crew members, especially during the first aeromedical examination, myocardial bridging is a good example.
Presentation of Case: A 24-year-old student pilot candidate shows repolarization disorders at the ECG in the aeromedical examination, the exploration allowed the discovery of a myocardial bridge on The Coronary computed tomographic angiography (CCTA) of the left anterior descending (LAD) coronary artery responsible for tight stenosis.
Discussion: The prevalence of MB varies according to the method of investigation, ranging from 2% in coronary angiography and 19% in coronary computed tomography to 42% in autopsy.The prevalence among active civilian aircrew (pilots and cabin crew) monitored at CEMPN is 0.4%, all revealed by electrocardiogram abnormalities.
MB are usually small and of no clinical significance, the myocardial bridge proximal segment has been associated with atherosclerosis. Symptomatic patients with myocardial bridges as their only cardiac abnormality may present with myocardial ischemia, acute coronary syndromes, coronary spasm, syncope or even sudden death.
The initial therapeutic strategy in the treatment of MB is medical management. Revascularization is indicated by PCI or surgery, including coronary artery bypass grafting (CABG) or myotomy in the case of symptoms recalcitrant to maximal medical treatment.
The aviation environment may expose aircrew to additional physiological stressors, including hypobaria, hypoxia and sustained acceleration (+Gz). Such exposure may present a risk if associated with cardiovascular abnormalities, potentially leading to incapacity to fly due to symptoms or complications of the myocardial bridge.
Conclusion: The myocardial bridge is an anatomical variant rather than a congenital anomaly with varied symptomatology (ECG abnormality, stable or unstable angina or sudden death), the aeromedical decision is made on a case-by-case basis, and makes a challenge diagnostic, particularly for asymptomatic crews.

Estimate of Fire Safety Management in Residential Buildings: A Structural Equation Modeling (SEM) Approach
Authors: Jembola Ayobami Dele
Published: November 2024

The devastating consequences of fire incidents have brought global attention to the need for a thorough understanding of the factors responsible for this menace in order to provide a lasting solution. Poor fire safety management in buildings contributes to our societies’ increasing susceptibility to fire disasters. Nigeria, like every other nation in the world, has experienced a number of fire incidents over the years, most of them occurring in residential buildings. Thus, the study aimed to estimate fire safety management in buildings that provide accommodation and sleeping facilities for individuals and/or households, such as apartments, hotels, and hostels, which are referred to as residential buildings. The study was conducted to fill the gaps in the existing literature and provide relevant policy recommendations to address the challenges in fire safety management. The study employed a cross-sectional research design. Primary data were collected from a random selection of one hundred and eighty respondents, including one hundred and twenty (120) building occupants, twelve (12) hostellers, and forty-eight (48) hoteliers, using a well-structured questionnaire. Descriptive statistics and structural equation modeling (SEM) were used to analyze the dataset collected. The study’s findings indicate that fire safety awareness, households/management commitment to fire safety policies and standards, and fire safety practices have significant positive impacts on fire safety management in residential buildings. Conversely, the cause of fire incidents has a significant negative impact on fire safety management in residential buildings, with P-values less than 0.05 under the regression weights. Additionally, the study revealed that the majority of fire incidents in residential buildings stem from human carelessness, errors, poor human behaviors, and malfunctioning mechanical and electrical equipment. Furthermore, the study showed that achieving fire safety management objectives in residential buildings requires a greater awareness of fire safety, a commitment to fire safety policies and standards, and the implementation of fire safety practices among residents, hoteliers, and hostellers. The study thus recommends that residents, hostellers, and hoteliers should adopt a positive attitude towards fire safety management; prioritize fire safety training, fire risk assessment, and routine maintenance of fire safety equipment; ensure the use of surge protectors for electrical equipment; and establish a well-planned and organized emergency action plan and evacuation procedure, complete with proper documentation, to create a standardized system for preventing, mitigating, preparing for, and responding to fire emergencies. Similarly, the fire service should intensify public enlightenment on fire safety management with strict enforcement of fire safety policies and standards to ensure uncompromised fire safety practices and effective fire safety management in buildings.

“Deciphering The Enigma Of Nasal & Paranasal Anatomy Through Computed Tomography (CT) Imaging”
Authors: Bakshi Dr. Vipin Kumar
Published: November 2024

Introduction: the paranasal sinuses are mucosa-lined structures physically contiguous with the nasal cavity that aid in insulation, reducing cranial weight, heating & humidifying the air, imparting resonance to the voice, providing airway defense and simply to replace functionless bone. Sinusitis is rarely life threatening, but the complex anatomy of the facial planes, the associated venous and lymphatic spread and the close location to the central nervous system can lead on to serious complications. It is, therefore, important to understand the normal anatomy of the paranasal sinuses in order to understand the pathogenesis of sinus disease. Hence, the aim of the present study was deciphering the role of ct as the investigation of choice for the preoperative evaluation of the nose & paranasal sinuses and for delineation of obstructive inflammatory sinus disease to aid in the diagnosis and management of recurrent & chronic disease and to define the bony anatomy before surgery. Materials and methods: prospective cross-sectional study was conducted on 100 asymptomatic patients who were getting investigated by computed tomography for non-sinus indications in whom the paranasal sinus region could be included in the field of study referred to department of radio-diagnosis and imaging from indoor and outdoor departments of jan sewa hospital of dr. S. S. Tantia medical college, sri ganganagar. Results: the majority of patients were in the age group of 21-40 years (42.3%) with 70% being male. Patients in the age group equaling or more than 61 years & with diabetes had the most number of incidental findings (68.2 %) agger nasi was the commonest anatomical paranasal sinus variant (82.9 %) followed by concha bullosa (39.3 %), deviation of the nasal septum (35.4 %), onodi cells ( 12.2 %) & haller cells ( 11.8 %). Incidental paranasal sinus abnormality in the form of mucosal thickening, sinus secretions or polyps were detected in 51.9 % patients, mucosal thickening being most common (40.1 %) followed by secretions (31.9 %) and mucosal polyps ( 3.0 %). Incidental paranasal abnormalities were most commonly noted in the ethmoid sinuses (36.7 %) followed by the maxillary sinuses, sphenoid sinuses and then frontal sinuses in descending order of involvement. Conclusion: computed tomography (ct) provides a “road map” for diagnosis and management of recurrent & chronic paranasal sinus disease and to delineate the bony anatomy before sinus surgery and to get an insight into anatomical variants apropos of their clinical relevance & impact on sinus disease.

Background: Thyroid disorders are the most common endocrine abnormality in the world secondary to diabetes mellitus. Thyroid hormones are essential for growth, neuronal development, reproduction and regulation of energy metabolism. It influences the metabolism of all substrates including minerals. Many studies have shown that mineral metabolism is frequently disturbed in thyroid disorders. Materials and Methods: The study was conducted on sixty newly confirmed hypothyroid cases based on the thyroid profile and sixty euthyroid cases were recruited as controls. Blood samples were collected from all the patients for the estimation of serum T3, T4, FT3, FT4, TSH, calcium, phosphorus and magnesium by auto analyzer method. Modified spectrophotometric micro-method was used to measure Serum copper using Bathocuprine Disulphonate Disodium Salt (BCDS) and Guanidine hydrochloride salt. The Statistical software namely SPSS 18.0, and R environment ver.3.2.2 were used for the analysis of the data. Results: It was found that the levels of serum sodium, potassium and calcium were significantly decreased in cases than the controls. Serum magnesium and phosphorus were significantly elevated in cases than controls. Conclusion: Serum calcium, magnesium and phosphorous levels are significantly altered in patients having hypothyroidism. Thyroid diseases have wide spread systemic manifestations including their effects on bone and mineral metabolism. Also thyroid hormone affects the glomerular filtration rate, renal blood flow, tubular reabsorption and excretion of minerals which have direct effect on Calcium, Magnesium and phosphorous level. Thus monitoring of these minerals in hypothyroid patient will be of great benefit in improving clinical manifestation and can be treated appropriately

Authors: Leite L. W. B. , Vieira W. W. S. , Ferreira A. D. S. , Andrade F. T. B.
Published: November 2024

The present work deals with a specific detail of the VSP technique for estimating local compressional, 𝑣𝑃, and shear, 𝑣𝑆 , wave velocities focused on reservoir characterization and seismic interpretation in sedimentary basins. This investigation was based on the presence of fluids (water, oil, gas) in porous rocks and its relationship with the 𝛾 = 𝑣𝑆 𝑣𝑃 ratio, which mainly affects the shear wave velocity. The forward modeling was based on the reflectivity method to simulate seismic sections along depth in the borehole, considering the presence of a reservoir formation with an anomalous 𝛾 ratio value. The seismic processing of the vertical, transversal, and radial components produced by VSP modeling was based on band-pass filtering for upward and downward field separation, semblance picking, and NMO correction for estimating 𝑣𝑃 and 𝑣𝑆 wave velocities. Additionally, we compare different semblance measures to validate the NMO correction. The results show an accurate estimate of the 𝛾 ratio in the target layer, even considering receivers at different depths and high noise levels in the VSP sections. Besides that, the 2D numerical experiment reveals information about the sensitivity of the 𝛾 parameter in a layered medium with velocity variation, principally around regions with the potential presence of oil and gas.
Mango forest Soil Nutritional Components Analysis and Research in Dong District of Panzhihua City
Authors: Jian XIONG
Published: November 2024

Purpose: the pH value of soil determines soil properties and determines whether the activities of plants and microbes in the soil are active or not. A large number of elements such as nitrogen, phosphorous and potassium in soil can reflect a basic characteristic of soil and play a guiding role in further fertilization and soil improvement. Organic matter can reflect the amount of humus in the soil, whether the soil is fertile, the fertility of the soil, and the activities of microbes in the soil. So, this study will focus on exploring the soil pH value, N, P, K factors such as organic matter, because the subjects as the mango trees, and Panzhihua is a large amount of planting mango region, therefore, to appeal the influence of factors on the mango is very direct, hope that the result of the experiment can provide some basic data on mango cultivation, to help farmers to further understanding of the nature of soil and fertilization. Methods: chemical measuring methods were applied to determine the soil pH, organic matter and N, P, K values or concentrations. Results: the average available phosphorus in the whole experimental area is only 5.24, which belongs to a slightly lower level. Conclusions: The content of phosphorus in the soil of mango forest is very low, and the phosphorus element is very deficient. It is suggested to apply phosphorus fertilizer, irrigate mango trees and reduce the pH value to improve the situation of low phosphorus

Published: November 2024

The huge cost and high labor demand associated with the current deep litter system of poultry farming poses a great challenge to poultry farming. These drawbacks which currently threatens this system of farming, have been attributed to the over-involvement of humans in almost all aspects of operation of this farming system. The consequences are increased disease outbreak, weakness and poor bird feeding. To ameliorated some of these challenges, an automated poultry feeding system is developed and presented in this paper. The proposed system mimics the roles of real-life poultry attendants in delivery of feed and water to birds at specified interval of time. The system controls the dispensing of poultry feed (liquid and solid) through a program written on ATmega328P microcontroller via the Arduino Uno. The system senses the level of feed and water in the respective trough and intelligently dispense water and feed in response to the sensed levels. The current system is able to effectively sense and predict the level of feed and water in the farm at an accuracy of 98.79% and dispense same within a response time of 50-60ms.

The paper, in assessing the trends, challenges, and the emerging technologies in respect of regulations within finance and investment, notes how the subject-matter of law and finance, with the attribution of power becoming increasingly multidimensional, leads to regulatory scrutiny against banks and other financial institutions, so there must be good mechanisms to deal with compliance. The core findings of the study indicate that while traditional compliance frameworks are cracking, the introduction of technologies, including blockchain and artificial intelligence, would provide offbeat solutions to enhance compliance effectiveness. However, newer technologies introduce an array of challenges as well, including that of data privacy and the need for reinventing the existing legal framework. The study argues for an articulated work linkage between financial institutions and the regulators along with the developers of the technology to build a flexible regulatory landscape which accommodates innovation alongside compliance. The study points towards collaborative efforts involving all stakeholders to ensure technology-enabled solutions are always present on the plate for consideration
An Analytical Study On The Correlation Between Soybean And Palm Oil Prices And The Interplay Of Market Forces
Authors: Bhatter Ishaan
Published: November 2024

This paper studies the price relationship between two important agricultural commodities: soybean oil and palm oil. For the analysis the following statistical methods – Pearson correlation and multivariate regression – have been used on a simulated dataset over a fifteen-year period. The present study unwraps the economic, environmental, and policy factors that contribute to their interconnected nature. While the results show a strong positive correlation between the two future prices, the outcomes also provide a much broader perspective on the role of economic conditions, including the global supply chain and demand spillover. Moreover, environmental trends and policy shifts together shape future price trends equally. In addition, the paper forecasts the possible future price trend of each commodity using ARIMA and helps to determine the market direction. This research contributes to the broader discussion on agricultural economics and commodity markets, offering a data-driven perspective that supports strategic planning and informed action in the face of market uncertainties and environmental challenges

Published: November 2024

The Inner Niger Delta (DIN) is a vast wetland where socio-economic activities (agriculture, livestock breeding, fishing, navigation) are dependent on its fairly complex hydrological regime whose hydrodynamic functioning depends on river inputs from the upstream basins: the upper Niger and Bani. The flooding surface of the DIN is closely linked to its hydrological regime. It was calculated by the HAV (Height-Area-Volume) model during the study period from 1960 to 2020. The HAV model is designed on the basis of two modules: physical and hydrological. The design of the physical module resulted in the development of the HAV matrix of DIN, calculation engine of hydrological module. The hydrological module is designed on MATLAB; it calculates the variation in the volume of stored water and converts it into flooded surface area. During the study period, the maximum flood area in the DIN was estimated at 37,252 km² in 1967 compared to 8,466 km² in 1993. She is observed from mid-October until the end of December, i.e. a duration of at least three and a half months (3.5 months). The flooded area generally reaches its maximum in November in the DIN

Electrostriction is a property of all naturally occurring dielectrics whereby they are mechanically deformed under the application of an electric field. It is demonstrated here that an artificial metamaterial nanostructure comprising arrays of dielectric nanowires, made of silicon and indium tin oxide, is reversibly structurally deformed under the application of an electric field, and that this reconfiguration is accompanied by substantial changes in optical transmission and reflection, thus providing a strong electro‐optic effect. Such metamaterials can be used as the functional elements of electro‐optic modulators in the visible to near‐infrared part of the spectrum. A modulator operating at 1550 nm with effective electrostriction and electro‐optic coefficients of order 10−13 m2 V−2 and 10−6 m V−1, respectively, is demonstrated. Transmission changes of up to 3.5% are obtained with a 500 mV control signal at a modulation frequency of ≈6.5 MHz. With a resonant optical response that can be spectrally tuned by design, modulators based on the artificial electrostrictive effect may be used for laser Q‐switching and mode‐locking among other applications that require modulation at megahertz frequencies.

The key bottlenecks hindering the practical implementations of lithium‐metal anodes in high‐energy‐density rechargeable batteries are the uncontrolled dendrite growth and infinite volume changes during charging and discharging, which lead to short lifespan and catastrophic safety hazards. In principle, these problems can be mitigated or even solved by loading lithium into a high‐surface‐area, conductive, and lithiophilic porous scaffold. However, a suitable material that can synchronously host a large loading amount of lithium and endure a large current density has not been achieved. Here, a lithiophilic 3D nanoporous nitrogen‐doped graphene as the sought‐after scaffold material for lithium anodes is reported. The high surface area, large porosity, and high conductivity of the nanoporous graphene concede not only dendrite‐free stripping/plating but also abundant open space accommodating volume fluctuations of lithium. This ingenious scaffold endows the lithium composite anode with a long‐term cycling stability and ultrahigh rate capability, significantly improving the charge storage performance of high‐energy‐density rechargeable lithium batteries.

As a type of flexible electronics, wearable heaters have attracted broad attention because of their giant potential market value, such as for use in wearable thermotherapy. Wearable heaters are required to simultaneously possess high stretchability and dynamic stability, in order to realize joints or muscles thermotherapy during exercising. Here, a high‐performance electrically driven heater using the conductive composite of liquid‐metal (LM) and polydimethylsiloxane (PDMS) is reported, which is patterned as sinusoidal structure by the printing technology of direct ink writing. Because high conductive LM is chosen as the active material, the LM@PDMS stretchable heater possesses high stretchability (>100% strain) and good conductivity (1.81 × 103 S cm−1). It also exhibits superb dynamic stability, due to the 3D conductive network of LM in matrix and the sinusoidal structure of the composite. While being stretched to the strain level of 100%, the heating temperature variation of LM@PDMS stretchable heater is less than 8%. This relatively low temperature variation is several times smaller than that of existing heaters at the same large strain levels. It is demonstrated that the LM@PDMS stretchable heater worn on the knee joint works well during strenuous exercise, thus proving great potential in wearable thermotherapy.
Bare Silica Opals for Real‐Time Humidity Sensing

Published: November 2018

The photonic properties of 3D colloidal crystals made of Stöber silica spheres are shown to significantly depend on the relative humidity of the environment. The photonic bandgap of bare artificial opals formed by hydrophilic silica markedly varies in humid air along the entire range of water vapor concentration without the need for infiltration of functionalization. The optical changes are highly sensitive to humidity variation (especially in low‐humidity range) and very fast response times of 60 ms, mainly ascribed to the absence of intermediate processes, the favorable bandgap characteristics (high intensity and sharp edges) and the high air accessibility to the open opal voids. Contrary to common approaches for photonic crystal sensors—seeking visual detection via large spectral shifts but having important shortcomings,—it is demonstrated that the well‐defined photonic bandgap of bare silica opals allows, even for moderate shifts, outstanding sensing performance by proper monitoring with inexpensive equipment (no spectroscopic detection is needed). As a result, the rapid and reproducible photonic response enables accurate, real‐time retrieval of the ambient humidity. The economical, one‐step fabrication, and the efficient performance make silica artificial opals suitable for a new type of precise, low‐cost, and real‐time humidity sensors.

Since their inception, quantum dots have proven to be advantageous for light management applications due to their high brightness and well‐controlled absorption, scattering, and emission properties. As quantum dots become commercially available at large scale, the need for robust, stable, and flexible optical components continues to drive the development of robust and flexible quantum dot composite materials. In this review, after a thorough introduction to quantum dots, discussion delves into methods for fabricating quantum dot loaded composite optical elements such as thin films, microfabricated patterns, and microstructures. The importance of surface chemistry and ligand engineering, host matrixes, wet processing, and unique patterning methodologies is presented by considering photostability, aggregation, and phase separation of quantum dots in corresponding composites. With regard to prospective optical applications of quantum dot materials, emphasis is placed on light emitting and guiding composite materials for lasing applications, specifically whispering gallery mode‐based photonic microsystems. These developments will enable novel flexible, portable, and miniaturized optoelectronic devices such as light‐emitting diodes, flexible pixelated displays, solar cells, large‐area microwaveguides, omnidirectional micromirrors, optical metasurfaces, and directional microlasers.
