Published: September 2024

The financial advisory sector in Nigeria, while pivotal for guiding investors and enhancing market efficiency, faces significant challenges related to trust. This paper presents a comprehensive trust-building model aimed at addressing the trust deficit within Nigeria’s investment sector. The model proposes a multifaceted approach to enhance trust through improved transparency, accountability, regulatory reforms, and client education. Trust is a crucial element in financial advisory services, influencing investor confidence and market stability. In Nigeria, historical issues such as regulatory inconsistencies, information asymmetry, and instances of financial misconduct have eroded trust between advisors and clients. The proposed trust-building model emphasizes four key areas: enhancing transparency and accountability, implementing regulatory reforms, improving financial literacy among investors, and leveraging technology. Transparency can be achieved through open disclosure of fees, commissions, and potential conflicts of interest, alongside standardized reporting mechanisms. Regulatory reforms are essential for strengthening oversight and enforcing ethical standards. Improving financial literacy involves educating clients about investment options and risks, empowering them to make informed decisions. Technology plays a critical role by offering real-time updates and personalized advice through fintech platforms and AI-driven tools. Case studies from both developed and developing markets highlight successful trust-building strategies, providing valuable insights for the Nigerian context. For instance, countries with robust regulatory frameworks and advanced technological integration offer practical examples of how transparency and accountability can be effectively implemented. Nigerian case studies demonstrate instances where trust-building initiatives have led to increased investor confidence and market stability. Despite the promising aspects of the model, challenges such as institutional resistance, economic instability, and entrenched industry practices may hinder implementation. Overcoming these barriers requires a collaborative effort from regulators, financial advisors, and investors. The model's anticipated impact includes greater investor confidence, market growth, and a more stable investment environment. By addressing the core issues affecting trust and fostering a culture of transparency and accountability, the proposed model aims to transform Nigeria’s financial advisory sector, ultimately contributing to its long-term development and stability.

Abstract. Volcanic degassing and explosive eruptions inject significant amounts of gas and ash into the atmosphere, impacting the local environment and atmospheric dynamics from local to global scales. While ground- and satellite-based remote sensing systems are key to describing explosive volcanism and assessing associated hazards, direct in situ measurements inside volcanic clouds are not possible with these methods. This study presents an innovative approach using an Unoccupied Aircraft System (UAS) for (i) airborne ash sampling and (ii) measurements of aerosol and gas concentrations (AeroVolc system). Commercial instruments (DJITM Matrice 30 Unoccupied Aerial Vehicle (UAV), AlphasenseTM N3 Optical Particle Counter OPC, SoarabilityTM Sniffer4D Mini2 multigas hardware) were combined with custom-built ash collectors and particle counters to enable a more detailed analysis of volcanic clouds. Here we showcase the deployment of our UAS on Sakurajima (Japan) and Etna (Italy), two volcanoes known for their frequent explosive eruptions and persistent degassing activity, to demonstrate how this approach enables in situ, high-resolution sample and data collection within challenging environments. Results provide grain size distributions (GSDs), information on the occurrence of particle aggregation, as well as solid aerosol (PM1, PM2.5, and PM10) and gas (SO2 and CO2) concentrations. Depending on whether the UAS was operated within or below ash- and/or gas-rich clouds, different insights were gained that open up new perspectives for volcanological research. These insights include the composition, concentration, generation, dispersion and sedimentation patterns of volcanic clouds.
Insights into Greenland Ice Sheet Surface Roughness from Ku-/Ka-band Radar Altimetry Surface Echo Strengths
Authors: Scanlan Kirk M. , Rutishauser Anja , Simonsen Sebastian B.
Published: September 2024

Abstract. Surface roughness is an important factor to consider when modelling mass fluxes at the Greenland Ice Sheet (GrIS) surface (i.e., surface mass balance, SMB). This is because it can have important implications for both sensible and latent heat fluxes between the atmosphere and the ice sheet and near-surface ventilation. While surface roughness can be quantified from ground-based, airborne and spaceborne observations, satellite radar datasets provide the unique combination of long-term, repeat observations across the entire GrIS and insensitivity to illumination conditions and cloud cover. In this study, we investigate the reliability and interpretation of a new type of surface roughness estimate derived from the analysis of Ku- and Ka-band airborne and spaceborne radar altimetry surface echo powers by comparing them to contemporaneous laser altimetry measurements. Airborne data are those acquired during the 2017 and 2019 CryoVEx campaigns while the satellite data (ESA CryoSat-2, CNES/ISRO SARAL, and NASA ICESat-2) are those acquired in November 2018. Our results show that because surface roughness across the GrIS is primarily scale-dependent, a revised empirical mapping of quantified radar backscattering to surface roughness gives a better match to the coincident laser altimetry observations than an analytical model that assumes scale-independent roughness. We also show that the radar altimetry-derived surface roughness is best interpreted as the wavelength-baseline linear projection of the scale-dependent surface roughness observed at hundreds of meter scales and is therefore not representative of individual small-scale features. These results provide critical context for interpreting the datasets and evaluating their applicability in modelling GrIS SMB.

Published: September 2024

Este artigo desenvolveu um duplo objetivo. Primeiro, correlacionar as investigações acerca da História Digital, com o ensino de História e os fundamentos da Educação (História da Educação, Filosofia da Educação, Sociologia da Educação, Psicologia da Educação). Para isso, adotou-se a cibercultura enquanto território da história vivida, por meio do qual ocorre o fazer-se de sujeitos sócio-históricos. Segundo, ao demonstrar a presença das discriminações sociorraciais na cibercultura, apontou-se a necessidade de se decolonizar a compreensão, as ações e as narrativas históricas presentes e desenvolvidas nesse território da história vivida digital. É a partir da convergência e do diálogo dos métodos de investigação historiográficos e educacionais que as análises das “práticas de educabilidade histórica digital” foram defendidas como meio de correlacionar aqueles dois objetivos.

This research delves into the properties of x% ZW-BT compounds (x=3% and 7%), synthesized using a solid-state reaction approach. Utilizing X-ray diffraction, the crystal structure of the x% ZW-BT compositions is confirmed, showcasing a distinct tetragonal symmetry devoid of any parasitic phases. With increasing dopant concentrations, slight reductions in lattice parameters are observed, signifying the even diffusion of dopant (Zn2+ and W6+) ions. Moreover, the validation of metal-oxygen bonding vibrations is achieved through Fourier-transform infrared spectroscopy (FTIR) analysis. Scanning electron microscopy (SEM) coupled with energy-dispersive X-ray spectroscopy (EDX) reveals consistent granular arrangements and clear elemental signatures in both compositions. Notably, photocatalytic experiments highlight remarkable degradation rates; within 100 minutes, 3% and 7% ZW-BT achieve degradation levels of 78.04% and 88.9% respectively. These findings underscore the significant potential of these compounds for environmentally friendly photocatalytic applications.

Highly energy efficient and ion permeable ion exchange membranes are in high demand in many modern sectors to clean water, transform energy, and store energy in devices like electro-dialyzer, fuel cells, and batteries. However, greater resistance and reduction in ion permeation of conventional membranes dictate the desire for nanostructured functional ion exchange membranes. This project proposes the fabrication of ion exchange membranes using electroactive nanostructured polyaniline incorporation into ion exchange materials, electrostatically interaction between polymer and nanostructured electroactive material overcomes the problem of high resistance and less ion permeation. Solution casting and post-drying techniques are used for membrane casting. Nanostructured electroactive material helps to increase ionic conduction thus reducing 17% resistance for functional cation exchange membrane (FCEM) and 12% for functional anion exchange membrane (FAEM) also assisting to increase ion permeation. Hydrophilic nanostructured polyaniline electroactive material holds more water and increases water uptake. Cross-linking increases stability as well as reduces 17% and 8% swelling degrees for FCEM and FAEM respectively. Besides the electrochemical property offers an increase limiting current density of 38%, 23% for FCEM and FAEM respectively, and 19% higher desalination performance than non-nanostructured sulfonated polyphenylene oxide (CEM) and quaternized polyphenylene oxide (AEM) membranes.
Kinetics of Electron Transfer Reaction Between Co(II) and Chlorate Ions: Isothermal Reactor Design and Experimental Validation
Authors: Mahwish M Khan Mahwish M Khan
Published: September 2024

The Batch Stirred Tank Reactor (BSTR) has been commonly used for decades in the chemical process industries and even on a pilot plant or laboratory scale whenever expensive and delicate raw materials and products such as pharmaceuticals or fragile transition metal complexes are involved. This research article describes the details of isothermal BSTR and subsequent experimental validation of the rate law discovered in the previous paper of this series on the electron transfer reaction between Co(II) and chlorate ions in acetic acid solution. A Series of tests were performed to evaluate the efficiency of the BSTR at multiple temperatures and illustrate the differences between the theoretical and experimental conversion of potassium chlorate through relative error. The experimental conversions are calculated with the design equation. Theoretical and experimental conversions are correlated and proportional to the initial concentrations of the reactant and electron transfer reaction among the reactants. Based on the parameters of the design equation, a set with average parameters was chosen and tested over BSTR. The model was then validated for different temperatures and conversions. A design equation for the BSTR has been written and applied for the conversions of 25%, 50%, 75%, and 95%. The time interval is going to be predicted by the model to achieve the desired conversions. The percent relative error between predicted and experimental conversions clearly shows the modeland#39;s predictability, power, and reliability. The precision of the observed rate constant for the electron transfer reaction is found to be 2.2023and#215;〖10〗^(-2 )%

Authors: I. U. Abasiofon, , E. G. Ukpong, , I. Nkanikpo,
Published: September 2024

The disclosure practices of firms may send strong signals to investors thus influencing their perceptions of the company’s risk and ethical standing and this potentially affects the company’s cost of capital. This study therefore examined the effect of corporate social responsibility disclosures on the cost of equity of listed deposit money banks in Nigeria. The research design adopted for this study was ex post facto and secondary data were used. The population of this study consisted of 13 deposit money banks and the sample size of this study was 11 purposively selected banks. The ordinary least square regression analysis was employed in analysing the data and the statistical package employed was E-views version 14. The findings of this study revealed that customer disclosures have a significant positive effect on the cost of equity; environmental responsibility disclosures have a positive but not statistically significant effect on the cost of equity while indigenous venture support disclosures have a significant negative effect on the cost of equity of listed deposit money banks in Nigeria. Based on the above findings, it was concluded that corporate social responsibility disclosures have a significant effect on the cost of equity of listed deposit banks in Nigeria. It was therefore recommended among others that management of deposit money banks should actively seek opportunities to engage with and support local entrepreneurs and transparently disclose these practices as investors are attracted to sustainable and eco-friendly firms thus reducing their risk premium in the cost of capital.

Published: September 2024

The high cost of cement and the associated environmental impact has necessitated many researchers to conduct investigations on alternative stabilizers. The research was aimed at assessing the properties of compressed earth bricks stabilized with locust bean pod powder (LBPP). It involved the addition of LBPP in 0%, 2.5%, 5%, 7.5%, and 10% for a curing period of 3, 7, and 14 days. The laterite used had sand (58%), silt (31%), clay (10.0%), and organic matter (1%). The liquid limit was 30.13%, plastic limit 15.46%, plasticity index 14.67%, shrinkage 1.7%, maximum dry density 1.7 g/cm3, and optimum moisture content 10%. Chemical oxide composition showed SiO2 to be 16.3%, CaO 13.6%, K2O 35.8%, SO3 4.18%, Cl2 3.16, Fe2O3 16.6%, and P2O5 7.64%. Results obtained from stabilized bricks showed that the compressive strength improved from 0.52 N/mm2 for 0% LBPP content at age 3 days to 2.7 N/mm2 for 10% LBPP content at 14 days. The bending strength also increases from 0.02 N/mm2 for 0% LBPP content at age 3 days to 0.25 N/mm2 for 10% LBPP content at 14 days curing age. The researcher concludes that LBPP contains cementitious properties and chemical oxides similar to that of Portland cement and that it improves the compressive and bending strengths of CSEB. The researcher recommends 10% LBPP content and a 14-day curing period for practical applications.

In the current study, the effects of age and breed on the quality of the semen of indigenous cattle breeds have been examined. Four indigenous cattle breeds from the sub-tropical region of India, including Gir, Rathi, Sahiwal, and Tharparkar, have been selected to know the effect of non-genetic factors on semen characteristics. The study used the data of three semen traits, viz. total ejaculation volume (EV; in ml), sperm motility (SM), and sperm concentration (SM; in million per ml), for analyzing the impact of age and breed (n = 8477), for the semen collected and preserved by Frozen Semen Bank, Bassi, Jaipur, India, from the pooled dataset of Information Network for Animal Productivity & Health (INAPH, 2017-2022). Except for SM, it was found that the impact was significant in connection to age as well; young age groups (18 to 30 to 31 to 43 months) produced the greatest results for all other semen traits, whereas adult groups (44 to 56 to 57 to 69 months) had the highest estimates for SM. During the study, it was found that Sahiwal bulls gave the highest estimated value for most of the semen traits while Rathi bulls showed the highest estimated values for EV. All seminal features were found to have the lowest values in Tharparkar bulls, and the overall breed influence was found to be non-significant.

The buccal mucosa is regarded as an ideal location for administering medications for both local and systemic absorption. Mucin and polymers interact chemically during the mucoadhesion process. Much emphasis has been paid to the use of mucoadhesive polymers in buccal medication delivery. There are now many mucoadhesive dosage forms available, including pills, patches, disks, wafers, ointments, and gels. Buccal patches stand out among them for their higher comfort and flexibility. With their effective carrier capacity, smart materials like stimuli-responsive hydrogels, liposome-based patches, polymeric micelles, etc. play a crucial role in the development of these drug delivery systems by extending the drug's residence time at the site of absorption, improving drug bioavailability, reducing the frequency of dosing, and increasing patient compliance. Different designs and production techniques, including as electrospinning, electrospraying, and 3D printing, are thought to be novel and effective ways to manufacture buccal patches with certain distinctive qualities in comparison to conventional procedures like solvent casting. Aiming to develop buccal mucoadhesive patches as a novel controlled drug delivery system, this review aims to examine and introduce the most promising smart polymeric materials, new designs, and production techniques.
A Review Article on Transdermal Drug Delivery System
Authors: Abhishek Abhishek , Katnauria Akshit , Happy Happy , Kumar Verma Kapil
Published: September 2024

When compared to more conventional drug delivery methods, transdermal administration has many benefits. High bioavailability, the lack of first pass hepatic metabolism, stable medication plasma concentrations, and the non-invasive nature of therapy are a few of these. The stratum corneum, the skin's topmost layer, is the main barrier to medication molecules penetrating it. The study of how to get beyond this layer and improve transdermal drug delivery (TDD) is therefore of great interest. The purpose of this review article is to offer a remark on the most current developments in TDD enhancement methods. Techniques to increase skin penetration have been developed to boost bioavailability and broaden the range of medications for which topical and transdermal distribution is an effective alternative. These approaches include drug selection, prodrugs and ion pairs, supersaturated drug solutions, eutectic systems, complexation, liposomes, vesicles, and particles. These enhancement strategies are centered on optimizing the interaction between the drug and the vehicle. Enhancement through hydration-induced stratum corneum change, chemical enhancers that affect the stratum corneum's lipid and keratin composition, and effects on partitioning and solubility are also covered. It is discussed how penetration enhancers and retarders work and how they could be used in therapeutic settings.

Published: September 2024

The spike protein of SARS-CoV-2, particularly its subunit Spike Protein 1 (S1), has been identified as a crucial component in the pathogenesis of COVID-19. Recent studies have revealed that SARS-CoV-2 Spike Protein 1 has the ability to activate microvascular endothelial cells, which play a vital role in maintaining vascular integrity and regulating inflammatory responses. This activation of microvascular endothelial cells by the spike protein has significant implications for COVID-19 pathogenesis. It can lead to endothelial dysfunction, increased vascular permeability, recruitment of immune cells, and the release of inflammatory molecules, contributing to the systemic inflammatory response observed in severe cases of COVID-19. Furthermore, it can exacerbate tissue damage and contribute to the cytokine storm. Understanding the mechanisms and consequences of SARS-CoV-2 Spike Protein 1-mediated activation of microvascular endothelial cells is crucial for developing targeted therapeutic interventions to mitigate the inflammatory response and improve patient outcomes. This knowledge may also guide the exploration of existing medications to modulate endothelial dysfunction and attenuate the pathogenic effects of spike protein activation. Continued research in this field is warranted to uncover precise mechanisms and develop effective strategies to combat this aspect of the disease.
