Authors: Egbeneje Victor O. , Okhale Samuel E. , Imoisi Chinyere , Ogbogo Isaac O. , Ojo Omolade 
Published: October 2023

The use of nanoparticles as corrosion inhibitors has gained popularity because of its increased corrosion efficiency due to increase surface to volume ratio. Nanoparticles which undergo physisorption/chemisorption to the corrosion metal surface and inhibit the corrosion efficiently also have low toxicity, low cost and easy production. In this research work, weight lost method was applied to study the inhibitive properties of silver nanoparticles (AgNPs) synthesized using Senna occidentalis root extract as environmentally benign corrosion inhibitor of mild steel in 0.5 M H2SO4 medium at 298 K and 308 K. It was observed that the corrosion rate of the steel sample decreases with increase in concentration of the silver nanoparticles but increased with rise in temperature. The highest inhibition efficiency of 65.59% was obtained at 308 K at the concentration of 5 gdm-3 and the least of 10.58% at the concentration of 1 gdm-3 at 308 K. The decrease in inhibition efficiency with rise in temperature is suggestive of physical adsorption mechanism. The surface coverage was observed to increase with increasing concentration of the nanoparticles and decreased with increase in temperature. This could be as a result of physical adsorption mechanism. The evaluated activation energy was found to be higher for the inhibited process than for the uninhibited process. The increase in apparent activation energy in the presence of the nanoparticles denotes physical adsorption mechanism, while the reverse is usually attributed to chemical adsorption. The negative values of heat of adsorption Qads suggest that the adsorption phenomenon is exothermic.

Published: October 2023

The post-pandemic business landscape in Africa is characterized by organizational non-performance, employee attrition, lack of resilience, and strategic thinking in recent times. It continues to generate public discussion, concerns, and scientific interest because of its negative impacts. The coronavirus pandemic has also heightened these concerns; though, organizations continue to grapple for ways to improve performance. However inadequate strategic thinking is prevalent and has not received adequate attention post-pandemic, particularly in Nigeria the giant of Africa owning to the population. Therefore, this study aims to determine the association between strategic thinking and the long-term performance of organizations in Nigeria with a representative sample of selected teaching hospitals in Ogun State Nigeria. This is due to the peculiarity of teaching hospitals to live and well-being and the peculiar erratic business environment in Nigeria. The investigation utilized a survey research design comprising 339 medical doctors (Registrars, Senior Registrars, and Consultants) from teaching hospitals in Ogun State, Nigeria. The technique of total enumeration was used. A validated semi-structured questionnaire was utilized to collect data for the study. The constructs' Cronbach's alpha reliability coefficients ranged from 0.88 to 0.92. The rate of response was 93.8%. For the analysis of the data descriptive and inferential statistics were employed (Pearson product-moment correlation and regression analysis). The data analysis revealed that strategic thinking had a significant positive effect on the organizational performance of teaching hospitals in Ogun State, Nigeria (Adj. R2 = 0.051, F(4, 313) = 5.295, p < 0.05). The study concluded that strategic thinking affects the organizational performance of teaching hospitals in Ogun State, Nigeria, and can ensure long-term survival. Due to the correlation between strategic thinking and organizational performance, it is recommended that organizations adopt strategic thinking and ensure that they comprehend its significance to organizational performance. Strategic thinking can be a solution for hospital organizations to remain resilient in uncertain times.
The Portrait of Public Relations Strategic Planning
Authors: Gandariani Titis 
Published: October 2023

Strategic planning is a concept for building a specific and comprehensive work plan. The concept importance of the strategic planning in public relations activities is to facilitate the preparation and analysis of a series of work plans to be carried out. The purpose of this paper is to observe and analyze a series of public relations strategic planning concepts from several pioneers, as Jhon Marston (1963), Cutlip, Center, Broom (2000), Ronald D.Smith (2002), Anne Gregory (2000). The writing method is a qualitative descriptive format. The result of observing is the concept development of strategic planning which was born based on the criticism and development of previous concepts. Making systematic strategic planning, needs to be done by public relations practitioners to facilitate work operations. There are many more specific strategic planning aproaches, although there is no single approach, the essence of planning according to certain elements must exist. This paper is expected to enrich academics’ knowledge, especialy communication science students and public relations practitioners in making effective and comprehensive strategic planning based on scientific concepts and theory.

Published: October 2023

In recent years, the field of hypersonics has witnessed substantial growth in research and development activities, driven by its diverse range of applications spanning both military and commercial sectors. Governments and private companies in several countries have made substantial investments in hypersonic technologies to gain a competitive edge, secure or enhance strategic capabilities, and bolster deterrence measures. In this rapidly evolving landscape, the ability to swiftly and accurately identify emerging technologies becomes paramount. Leveraging the advancements in information technology and computer science, which enable the analysis of vast datasets and the extraction of concealed trends and patterns, this study aims to provide valuable insights to decision-makers in the hypersonics domain. Our focus is on scientific publications related to hypersonics, encompassing the years 2000 to 2020. We employ state-of-the-art natural language processing and machine learning techniques to comprehensively characterize the research landscape. The urgency of this endeavor lies in the necessity for organizations to remain at the forefront of hypersonic research. By algorithmically identifying and tracking 12 key latent research themes and examining their temporal evolution, we offer a structured and objective analysis of the field. Our methodology eliminates subjectivity from the assessment, facilitating consistent comparisons both across topics and across different time intervals. In addition, through our extensive publication similarity analysis, we uncover nuanced patterns that shed light on the cyclical nature of research trends over the two decades under investigation. This comprehensive examination of the hypersonics research landscape not only underscores its critical significance but also provides a robust foundation for informed decision-making. As such, our study serves as a valuable resource for stakeholders seeking to navigate the dynamics of the rapidly advancing field of hypersonics effectively.

O presente trabalho teve por objetivo apresentar os dados de um mapeamento geológico focado no minério de areia branca média (ABM) na região rural entre os municípios de Itaquitinga e Goiana, estado de Pernambuco, numa área de 36 km², localizados geologicamente na sub-bacia Olinda. Os resultados permitiram contribuir para o entendimento da geologia local e gênese do depósito mineral colúvio-eluvial em superfície e subsuperfície para fins de exploração e explotação do minério ABM. A partir da análise de furos de sondagem disponibilizados pela empresa Itapessoca Agro Industrial, bem como com os dados coletados no trabalho de campo, foram elaborados mapa geológico e mapa de ocorrência do minério ABM, ambos em detalhe (escala 1:15.000). Foram realizados ensaios físicos que permitiram caracterizar o minério como areia branca média pobremente selecionada, subangulosa a subarredonda. Os resultados das análises químicas nas amostras de ABM revelaram teores médios altíssimos de SiO2 de 98,61%, bem como teores baixos dos principais elementos deletérios (TiO2 de 0,29%, Al2O3 de 0,69% e Fe2O3 de 0,12%), dentre outros. O minério ABM integra estratigraficamente o conjunto dos depósitos colúvio-eluviais, que se apresenta cobrindo a Fm. Barreiras na forma de “sheet sands”, e tem sua origem associada a um processo de intemperismo químico decorrentes da circulação de água meteórica. O intemperismo químico, causado pela presença de águas pluviais, gerou uma intensa lixiviação na Fm. Barreiras, criando como produto residual a formação de depósitos arenosos de areia, que foram classificadas e individualizadas em areia branca média (ABM), areia cinza clara média (ACcM) e aAreia cinza escura média (ACeM), localizados no topo e nas encostas dos tabuleiros costeiros. Os resultados deste trabalho demonstraram que a ABM se classifica como um recurso mineral indicado, com reserva provável de aproximadamente 12,1 M ton na área estudada e que se apresenta como minério economicamente viável para explotação por satisfazer as demandas industriais da construção civil.

Use of MRI and CT in Private Imaging Facilities in Canada (2021-2023)
Authors: CADTH  
Published: October 2023

The private, for-profit imaging landscape is expanding and is anticipated to continue expanding due to changes in some provincial government policies aimed at reducing wait lists.
The collection of data on private imaging can help to build a complete and comprehensive picture of overall procedural capacity across the country.
Estimates on the number of publicly funded exams conducted in private facilities can inform the extent to which wait times have been impacted by the shift in some provincial government policies.
The number of MRI and CT exams conducted at private facilities has increased over the past 4 fiscal years, with the exception of the first year of the COVID-19 pandemic (2020 to 2021).
Payment through private insurance and out-of-pocket payments were the main funding sources for MRI scans in 2021 to 2023 in the private setting. Provincial health care insurance was the main funding source for CT scans conducted at private facilities.
A physically based correction for stray light in Brewer spectrophotometer data analysis
Authors: Savastiouk Vladimir , Diémoz Henri , McElroy C. Thomas 
Published: October 2023

Abstract. Brewer ozone spectrophotometers have become an integral part of the global ground-based ozone monitoring network collecting data since the early 1980s. The double-monochromator Brewer version (MkIII) was introduced in 1992. With the Brewer hardware being so robust, both single- and double-monochromator instruments are still in use. The main difference between the single Brewers and the double Brewers is the much lower stray light in the double instrument. Laser scans estimate the rejection level of the single Brewers to be 10−4.5, while the doubles improve this to 10−8, virtually eliminating the effects of stray light. For a typical single-monochromator Brewer, stray light leads to an underestimation of ozone of approximately 1 % at 1000 DU ozone slant column density (SCD) and can exceed 5 % at 2000 DU, while underestimation of sulfur dioxide reaches 30 DU when no sulfur dioxide is present. This is because even a small additional stray light contribution at shorter wavelengths significantly reduces the calculated SCD at large values. An algorithm for stray light correction based on the physics of the instrument response to stray light (PHYCS) has been developed. The simple assumption is that count rates measured at any wavelength have a contribution from stray light from longer, and thus brighter, wavelengths because of the ozone cross-section gradient leading to a rapid change in intensity as a function of wavelength. Using the longest measured wavelength (320 nm) as a proxy for the overall brightness provides an estimate of this contribution. The sole parameter, on the order of 0.2 % to 0.6 %, that describes the percentage of light at the longest wavelength to be subtracted from all channels is determined by comparing ozone calculations from single- and double-monochromator Brewers making measurements side-by-side. Removing this additional count rate from the signal mathematically before deriving ozone corrects for the extra photons scattering within the instrument that produce the stray light effect. Analyzing historical data from co-located single- and double-monochromator Brewers provides an estimate of how the stray light contribution changes over time in an instrument. The corrected count rates of the measured wavelengths can also be used to improve other calculations: the sulfur dioxide column and the aerosol optical depth, the effective temperature of the ozone layer, or any other products. A multi-platform implementation of PHYCS, rmstray, to correct the count rates for stray light and save the corrected values in a new B-file for use with any existing Brewer data analysis software is available to the global Brewer user community at https://doi.org/10.5281/zenodo.8097038 (Savastiouk and Diémoz, 2023).
Technical note: Discrete in situ vapor sampling for subsequent lab-based water stable isotope analysis
Authors: Herbstritt Barbara , Gralher Benjamin , Seeger Stefan , Rinderer Michael , Weiler Markus 
Published: October 2023

Abstract. Methodological advancements have been made in in situ observations of water stable isotopes that have provided valuable insights into ecohydrological processes. The continuous measurement capabilities of laser-based analyzers allow for high temporal resolutions and non-destructive minimally invasive study designs of such in situ approaches. However, isotope analyzers are expensive, heavy, and require shelter and access to electrical power, which impedes many in situ assays. Therefore, we developed a new inexpensive technique to collect discrete water vapor samples in the field via diffusion-tight inflatable bags that can later be analyzed in the lab. In a series of structured experiments, we tested different procedural settings, bag materials, and closure types for diffusion tightness during storage as well as for practical handling during filling and extraction. To facilitate reuse of sampling bags, we present a conditioning procedure using ambient air as primer. In order to validate our method, direct measurements through hydrophobic in situ probes were compared to repeated measurements of vapor sampled with our bags from the same source. All steps are summarized in a detailed standard operating procedure (SOP). This procedure represents the preparation and measurement of calibration and validation vapor standards necessary for processing of unknown field-collected vapor samples in the foreseen application. By performing pertinent calibration procedures, accuracy was better than 0.4 ‰ for δ18O and 1.9 ‰ for δ2H after 1 d of storage. Our technique is particularly suitable when used in combination with minimally invasive water vapor sampling in situ probes that have already been employed for soils and tree xylem. It is an important step towards minimally invasive monitoring of stable isotope distributions and also time series in virtually undisturbed soils and trees without the need to have an analyzer in the field. It is therefore a promising tool for many applications in ecohydrology and meteorology.

Published: October 2023

Abstract. The size and density of a population are essential parameters in primate ecology and conservation. Such information, however, is still scarce for many forest primate species. The Djaffa Mountains guereza (Colobus guereza gallarum) is an endemic Ethiopian taxon for which data about its distribution and population size are missing. Therefore, we aimed to estimate the abundance and population size of the Djaffa Mountains guereza in four forests in the Ahmar Mountains southeast of the Ethiopian Rift Valley. We conducted line-transect surveys in the forests. Within an area of 183 km2, we sampled 19 transects covering a distance of 75.9 km. We encountered 73 guereza clusters which most likely represent social groups. Since the detection distances and cluster sizes did not differ among the four forests, we applied a conventional distance sampling (CDS) model and estimated a population density of 20.6 clusters per square kilometer, i.e., 109.6 individuals per square kilometer or 20 061 individuals within the complete study area. This abundance is relatively high compared to other C. guereza taxa. However, given that the habitat and population of C. g. gallarum are already highly fragmented, further monitoring of the population and exploration of the possibilities of reconnecting its habitat should be priorities for the conservation of this taxon.
The Mortality Narratives in Cultural Representations: Themes and Tropes in Malayalam Cinema
Authors: Gopinath Swapna 
Published: October 2023

Malayalam cinema is a vibrant creative space that post 1990s, underwent a transformation, leading to a proliferation of films, uniquely experimental in nature. An interesting perspective explored in detail was that of mortality, analysis of death from a microcosmic perspective. Evaluating death as an event in Deleuzian framework enables us to gain interesting insights and the film used for study here is Ee. Ma. Yau. (2018) which has a funeral foregrounded in the narrative. The paper traces the encounter with death in popular films, over time, to comprehend social discourses built around mortality in India, specifically in the southern state of Kerala in India. Death and the social interventions in this context emerge as aspects significant for this study.
Analysis of a Second-Order Factor Model of Attitude Toward Mathematics
Authors: Gün Özge , Bulut Safure 
Published: October 2023

Based on a multidimensional definition of attitude, this study tested a second-order factor model of attitude toward mathematics using data from 1960 7th-grade students. This study found that students’ attitudes toward mathematics are identified with cognitive, affective, and behavioral factors. This study confirmed three hypotheses: the cognitive component of attitude toward mathematics is explained by students’ confidence in learning mathematics and their beliefs about the usefulness and importance of mathematics; the affective component of attitude toward mathematics is explained by their liking of mathematics and mathematics anxiety; and the behavioral component of attitude toward mathematics is explained by learner behaviors toward mathematics and the time they spent on mathematics at home. Moreover, the final model obtained through factor analysis revealed strong relationships between the three components of attitude and attitude toward mathematics.
