Socio-Demographic and Cultural Factors Influencing Male Spouses’ Support for Cervical Cancer Screening Among Women in Kiambu County, Kenya
Authors: Njoki Waititu Teresia , Oyore (PhD) John Paul , Barasa (PhD) Sarah Fedha
Published: October 2024

Cervical cancer remains a significant global health concern, especially in low and middle-income countries, despite the availability of effective screening methods. While various factors contribute to the suboptimal uptake of screening among women of reproductive age, spousal support particularly from male partners has emerged as a crucial element in encouraging participation. This study explores the influence of male partners’ support on cervical cancer screening behavior, examining the socio-demographic, cultural, and regional factors that shape this dynamic. This study employed a cross-sectional survey design to explore the factors influencing cervical cancer screening rates among women and their male partners in Kiambu County, focusing on sociodemographic factors of the male partner as the independent variable and cervical cancer screening uptake among women as the dependent variable. Data was collected from n=384 respondents at Thika and Kiambu Level V hospitals, utilizing structured questionnaires and interviews. Convenience and purposive sampling were used to select participants, while data reliability was ensured through pre-tests and Cronbach’s Alpha (0.71). The study achieved a 98% response rate, analyzed qualitative data through thematic analysis, and quantitative data descriptively, revealing key insights into partner knowledge, cultural influences, and spousal support in cervical cancer screening. This discussion examines the intricate relationship between socio-demographic and cultural factors and male spousal support for cervical cancer screening among female partners’ and reveals a significant knowledge gap among men regarding cervical cancer, its association with HPV, and the importance of preventive measures, which limits their advocacy for their partners’ health. Additionally, traditional gender roles, cultural norms, and societal attitudes create barriers to open communication and collaborative healthcare decision-making within families. Misconceptions, such as the belief that cervical cancer is linked to sexual promiscuity, further fuel stigma and discourage male support for screening. Religious beliefs and fear of societal judgment also contribute to men’s hesitancy in promoting their partners’ participation in screening. The findings emphasize on the need for targeted education initiatives and cultural sensitivity in addressing these barriers, ultimately enhancing male support and improving cervical cancer screening rates.

Published: October 2024

The study investigated attitudes of student teachers towards using corporal punishment in Eastern Cape schools where the practice continues even though it became illegal in 1996. Qualitative and quantitative research methods were used with purposive sampling. The study was based on the 2021 final year Postgraduate Certificate in Education (PGCE) students who were about to start teaching. A mixed method approach was used, adopting three data collection methods: an online questionnaire, focus groups, and semi-structured interviews. Bronfenbrenner’s ecological systems theory complemented by the theory of planned behaviour provided the theoretical framework for this study. These theories allowed the researcher to look at how various social contexts impact and influence an individual’s attitudes and practices. Findings showed that student teachers experience a dilemma towards using corporal punishment as a discipline strategy due to various factors such as school context, student teacher personality traits, power relations between the students and teachers who mentored them and the quality of training at institutional level. Furthermore, findings showed that understanding attitudes of student teachers towards using corporal punishment as a discipline strategy despite the ban is a complex issue. 75,5 % of the student teachers are sure of the value of using corporal punishment despite its illegality and have continued using it during teaching practice. Some student teachers are in a dilemma in seeing corporal punishment as necessary and a last resort discipline strategy. 24,6% of the student teachers indicated having a negative attitude towards using corporal punishment. Based on the evidence shown the study concludes that some student teachers are going to use corporal punishment, some may use it, therefore it is likely for corporal punishment to be used by student teachers despite the ban.

Published: October 2024

The article presents theoretical studies aimed at understanding the physical processes occurring in the production of compound feeds using a centrifugal cascade mixer, which open up new horizons in optimizing feed production technology. Special attention in these studies is paid to the analysis of the mixing process, which, as it turned out, is closely interrelated with the principles of operation of the dispenser. As a result of the analysis, it was found that the dispenser and mixer should be considered as a single system, regardless of the mixing mechanism used in the production process. This made it possible to develop a cascade mixer of feed materials of centrifugal type and continuous action, which is an innovative solution in the field of feed production. This mixer provides a homogeneous mixture of loose feed components and can be integrated into production lines for the preparation of both feed and combined mineral briquettes. The key advantage of the proposed mixer is the use of a centrifugal force field, which, unlike the gravity field, provides more efficient mixing. In this case, the process of preparing compound feeds can be represented as a sequence of three key stages: the metered supply of components, the introduction of one component into the composition of another, transportation (removal) of the finished product from the working area of the mixer. The research allowed us to obtain analytical dependences of the components of the centrifugal force on the angular velocity of the rotor and its radius. This allows you to optimize the operating parameters of the mixer to achieve maximum mixing efficiency. During the research, a mathematical model of the spatial motion of a particle in a mixer was developed. The model is presented in the form of Lagrange equations of the second kind, the generalized coordinates of which are the displacement of the particle along the cone and the polar angle of the particle position. This makes it possible to solve the optimization problems of centrifugal mixers according to a given objective function. Thanks to the conducted research, it was possible to develop an innovative mixer that provides a homogeneous mixture of components of loose compound feeds. The use of centrifugal forces in the mixer made it possible to increase the mixing efficiency and ensure that the final product meets the requirements of the formulation. The research results are of great practical importance and can be used to improve feed production technologies.

Carotid artery stenosis: diagnosis and guidelines for management
Authors: Lee Younseok , Park Jung Hyun
Published: October 2024

In carotid artery stenosis, the carotid arteries become blocked by fatty cholesterol deposits. Older individuals with high cardiovascular risk are disproportionately susceptible to this condition, for which risk factors include smoking, high cholesterol, male sex, and older age. When the vascular endothelium is damaged by the above-mentioned causes, low-density lipoproteins invade the inside of the endothelium and undergo an oxidation process. Monocytes infiltrate the endothelium in response to oxidized low-density lipoproteins and transform into lipid-laden macrophages, thereby activating inflammatory responses. As this inflammatory reaction progresses further, various decomposing enzymes are secreted, causing the atherosclerotic plaque to rupture and various thrombogenic materials to be secreted into the blood, resulting in the formation of blood clots and vascular stenosis or occlusion. This can cause symptoms ranging from mild, such as blurred-vision, to severe, such as life-threatening stroke. Carotid artery stenosis accounts for approximately 10% of all strokes. Therefore, early diagnosis and appropriate management are very important. When choosing between medical and surgical treatment, it is necessary to consider various factors, such as patient characteristics, symptoms, risk factors, and imaging results. In this review, we discuss the pathophysiology of carotid artery stenosis, risk factors, and the importance of prompt diagnosis and treatment. In particular, we focus on how to determine the need for treatment and select management methods for each individual patient.
CRISPR Technologies for In Vivo and Ex Vivo Gene Editing
Authors: CDA-AMC
Published: October 2024

What Is the Issue?
The first therapeutics based on clustered regularly interspaced short palindromic repeats (CRISPR) technologies are entering the market. These gene-editing technologies have the potential to change treatment paradigms and may be used to treat conditions that cannot be treated or cured with current methods. This report aims to provide an overview of these technologies and their current and potential roles in health care.
What Is the Technology?
CRISPR is a novel and emerging technology, first discovered in bacterial immune systems, that can cut DNA strands and be used as a gene-editing tool. A guide ribonucleic acid (RNA) sequence leads the CRISPR-associated nuclease to the target DNA sequence where the cut is made. These edits change the function of the gene, making genes nonfunctional or replacing the coding sequence for 1 gene with another. CRISPR can also be used to increase or decrease the expression of specific genes.
What Is the Potential Impact?
CRISPR-based technologies have a variety of potential applications in health care, including:

treating genetic diseases
understanding the genetic mechanisms of diseases and investigating the relevance of potential drug treatments
managing infectious diseases through detection, treatment, and elimination.

What Else Do We Need to Know?
The long-term effects of CRISPR-based therapies are currently unknown. While the first of these therapies, exagamglogene autotemcel (exa-cel) (Casgevy), is the first and only CRISPR-based therapy to receive regulatory approval anywhere internationally (e.g., US, UK), as well as in Canada in September 2024, the next viable CRISPR-based therapies are still in development, with the pivotal clinical trials not expected to be completed until at least 2027. Several ethical considerations related to the use of CRISPR-based therapies have been identified, including the implications of off-target gene modifications, a need for robust informed consent processes, and a need for ethical and legal guidelines.

Данная статья посвящена рассмотрению и анализу гендерного вопроса Духовно-рыцарских Орденов и Крестовых походов.Целью данной статьи является рассмотрение такого сложного исторического явления как участие женщин в духовно-рыцарских ордена и крестовых походах, что позволяет нам более объективно рассмотреть данный феномен, дав новую точку зрение на происходившие тогда события, показывая также как разные уставы (августинский или бенедиктинский) влияли на отношения к женщинам в разных Орденах -от полного их неприятия до достаточно значимых ролей в иерархии Ордена. Также затрагивается роль сестёр мирянок, которые зачастую были богаты и влиятельны.Актуальность проблематики данной статьи выражена в том, что представлен современный взгляд казахстанских исследователей на гендерный вопрос крестовых походов, в частности роли сестёр госпи-тальерок на основе анализа латинских исторических источников и современных трудов западных ученых. На современном этапе изучения деятельности духовно-рыцарских орденов в условиях Крестовых походов появляются работы по исследованию роли женщин в Орденах, поскольку гендерный вопрос, ранее практически не затрагивающийся, на сегодняшний день, является одним из наиболее важных в исследовании данной проблематики.При работе над статьей были использованы различные научные методы и подходы не только исторической дисциплины как таковой, но и междисциплинарные методы.

Published: October 2024

A infecção por HIV/AIDS entre a população idosa no Paraná é uma preocupação crescente, com um aumento significativo de casos entre indivíduos acima de 60 anos entre 2012 e 2022. Essa tendência revela falhas nas políticas de prevenção, que frequentemente desconsideram as necessidades dos idosos, uma faixa etária que, apesar de mais ativa sexualmente devido ao aumento da longevidade, carece de informações sobre práticas seguras e prevenção. O estigma social relacionado à sexualidade na terceira idade e a falta de educação sexual são fatores que contribuem para comportamentos de risco, como o sexo desprotegido. Além disso, a presença de comorbidades e a polifarmácia complicam o tratamento do HIV, tornando essencial uma abordagem multidisciplinar que integre saúde física e mental. O estudo aponta para a necessidade urgente de políticas públicas adaptadas, campanhas educativas específicas e suporte social, visando não apenas a redução da incidência de novos casos, mas também a melhoria da qualidade de vida dos idosos que convivem com a doença.

Abstract. The representation of aerosol activation is a key source of uncertainty in global composition-climate model simulations of aerosol-cloud interactions. The Abdul-Razzak and Ghan (ARG) activation parameterization is used in several global and regional models that employ modal aerosol microphysics schemes. In this study, we investigate the ability of the ARG parameterization to reproduce simulations with a cloud parcel model, and find its performance is sensitive to the geometric standard deviations (widths) of the lognormal aerosol modes. We recommend adjustments to three constant parameters in the ARG equations, which improve the performance of the parameterization for small mode widths and its ability to simulate activation in polluted conditions. For the accumulation mode width of 1.4 used in the Met Office Unified Model (UM), our modifications decrease the mean bias in the activated fraction of aerosols compared to a cloud parcel model from -6.6 % to +1.2 %. We implemented our improvements in the UM and compared simulated global cloud droplet concentrations with satellite observations. The simulated cloud radiative effect changes by -1.43 Wm-2 and aerosol indirect radiative forcing over the industrial period changes by -0.10 Wm-2.

Abstract. Lacustrine sediments are natural archives for the surrounding area's biogeochemical dynamics; in particular, the isolation and extreme conditions in which desert lakes are located make them ideal study models for studying perturbations in the ecosystem. Specifically, Inka-Coya Lake is in the Atacama Desert, where the presence of metals and metalloids associated with the active geological activity and local mining industry is a crucial driver for the biological dynamics in this ecosystem, as have been suggested for macroinvertebrates and plankton communities in the lake. In this study, we aimed to characterize the microbial communities that inhabit deep lacustrine sediments and their interaction with the surrounding environment. The results show that the microbial community from lacustrine sediments contains over 70 % unclassified organisms, highlighting this ecosystem's microbial taxonomic novelty. Our results indicate that the microbial communities cluster in three distinct zones: a superficial community, an intermediate and mixed community, and a more specialized anaerobic community in the deeper sediments. The microbial composition is dominated by chemoheterotrophic bacteria strongly associated with methane metabolism. Additionally, there is statistical evidence of strong correlations between particular taxa such as Sulfurimonadaceae, Metanoregulaceae, and Ktedonobacteroceae with elements like Cu, As, Fe, Ni, and V, and magnetic properties of the surrounding environment. Further detailed studies of the metabolic repertoire of these communities are necessary to understand the complex dynamics between microbial life and geochemical composition in this fragile and extreme environment.
Recent observations and glacier modeling point towards near complete glacier loss in western Austria (Ötztal and Stubai mountain range) if 1.5 °C is not met

Published: October 2024

Abstract. Most glaciers in Austria are expected to disappear in the coming decades. The general trend to deglaciation is apparent from observations of past glacier change as well as projections of future glacier evolution in the region. However, the projected timing of ice loss varies considerably between models and data sources. We enhance observations of regional glacier area and volume change with a new inventory for the Ötztal and Stubai range in western Austria and use this data to initialize and calibrate the Open Global Glacier Model (OGGM), generating projections for all glaciers in the study region until 2100 under different climate scenarios. Observations show that approximately 19 % of glacier area and 23 % of glacier volume were lost between 2006 and 2017 (values are relative to 2006 area and volume and equivalent to annual loss rates of 1.7 % and 2.1 %, respectively). Five glaciers disappeared between 2006 and 2017 and are no longer included in the 2017 inventory. Estimating future change by extrapolating the change rates observed between 2006 and 2017 produces a considerably slower glacier decline than the model projections for all scenarios, highlighting the need for dynamic, climate-aware glacier models to quantify the range of possible futures and trajectories to deglaciation. By adapting OGGM to incorporate the multitemporal, high-resolution observational data available for the study region, the model performance improved compared to using global, lower resolution data and, for the first time, enabled the model to simultaneously match observed area and volume changes at a regional scale. This increases confidence in the regional projections, which show 2.7 % of the 2017 glacier volume in the region remaining by 2100 in a global warming scenario of +1.5 °C above pre-industrial temperatures. Applying a +2 °C scenario, this volume is reached around 30 years earlier and deglaciation is near complete by 2100 (0.4 % of 2017 volume remaining). Gepatschferner, the largest glacier in the region, is expected to retain 5.4 % of its 2017 volume in a +1.5 °C scenario and 0.4 % in a +2 °C scenario. Over 100 glaciers, i.e. roughly one third of the glaciers in the study region, are likely to disappear by 2030 even in the +1.5 °C scenario. Glacier loss in the study region under current warming trajectories (+2.7 °C) is expected to be near total before 2075 (less than 1 % of 2017 volume remaining).
Impacts of Sea Ice Leads on Sea Salt Aerosols and Atmospheric Chemistry in the Arctic
Authors: Emme Erin , Horowitz Hannah
Published: October 2024

Abstract. Sea salt aerosols (SSA) alter Arctic climate through interactions with radiation and clouds. The processes contributing to Arctic cold season (November–April) SSA remain uncertain. Observations from coastal Alaska suggest emissions from open leads in sea ice, which are not included in climate models, may play a dominant role. Their Arctic-wide significance has not yet been quantified. Here, we combine satellite data of lead area (the AMSR-E product) and a chemical transport model (GEOS-Chem) to quantify pan-Arctic SSA emissions from leads during the cold season from 2002–2008 and predict their impacts on atmospheric chemistry. Lead emissions vary seasonally and interannually. Total monthly SSA emissions increase by 1.0–1.8 % (≥60° N latitude) and 5.8–8.4 % (≥75° N). The AMSR-E product detects at least 50 % of total lead area as compared to optical MODIS satellite images. SSA concentrations increase primarily at the location of leads, where standard model concentrations are low. GEOS-Chem overestimates SSA concentrations at Arctic sites even when lead emissions are not included, suggesting underestimation of SSA sinks and/or uncertainties in SSA emissions from blowing snow and open leads. Multi-year monthly mean surface bromine atom (Br) concentrations increase 2.8–8.8 % due to SSAs from leads. Changes in ozone concentrations are negligible. While leads contribute <10 % to Arctic-wide SSA emissions in the years 2002–2008, these emissions occur in regions of low background aerosol concentrations. Leads are also expected to increase in frequency under future climate change. Thus, lead SSA emissions could have significant impacts on Arctic climate.
The impact of synoptic storm likelihood on European subseasonal forecast uncertainty and their modulation by the stratosphere

Published: October 2024

Abstract. Weather forecasts at subseasonal-to-seasonal (S2S) timescales have little forecast skill in the troposphere: individual ensemble members are mostly uncorrelated and span a range of atmospheric evolutions that are possible for the given set of external forcings. The uncertainty of such a probabilistic forecast is then determined by this range of possible evolutions – often quantified in terms of ensemble spread. Various dynamical processes can affect the ensemble spread within a given region, including extreme events simulated in individual members. For forecasts of geopotential height at 1000 hPa (Z1000) over Europe, such extremes are mainly comprised of synoptic storms propagating along the North Atlantic storm track. We use ECMWF reforecasts from the S2S database to investigate the connection between different storm characteristics and ensemble spread in more detail. We find that the presence of storms in individual ensemble members at S2S timescales contributes about 20 % to the total Z1000 forecast uncertainty over northern Europe. Furthermore, certain atmospheric conditions associated with substantial anomalies in the North Atlantic storm track show reduced Z1000 ensemble spread over northern Europe. For example, during periods with a weak stratospheric polar vortex, the genesis frequency of Euro-Atlantic storms is reduced and their tracks are shifted equatorwards. As a result, we find weaker storm magnitudes and lower storm counts, and hence anomalously low subseasonal ensemble spread, over northern Europe.

Historial roots and future pathways: Centring disaster justice in the Brazilian Amazon forest fires
Authors: Sepulveda Ariel
Published: October 2024

Over the past decade, forest fires in the Brazilian Amazon have surged due to deforestation, weak governance, and agribusiness expansion, creating a highly flammable environment. Often portrayed as natural disasters, these fires are not isolated incidents, but rather the culmination of historical, political, and economic factors that have systematically favoured profit over environmental protection. As such events expose existing vulnerabilities, affected communities are left with few resources to adequately recover. This briefing paper addresses how disaster justice can be ensured in such communities and how disaster events can be prevented and managed in the future.

CFD modeling of DME synthesis based on methanol dehydration process by an adiabatic reactor: Characterization
Authors: Mofidian Roozbeh
Published: October 2024

Today, Dimethyl ether (DME) can be used as a fuel in various applications, including as a substitute for diesel fuel. Despite its advantages, there are some challenges associated with DME as a fuel. One of the main challenges is the limited availability of DME refueling stations and the need for dedicated storage facilities due to their different properties compared to traditional fuels. DME shows promise as a clean-burning alternative fuel with the potential to reduce emissions and dependence on fossil fuels, especially in the transportation and power generation sectors. Ongoing research and development efforts are focused on improving production methods, expanding infrastructure, and exploring new applications for DME as a fuel. DME is a colorless gas that can be used as a fuel or as a precursor for the production of other chemicals. The most common method for DME synthesis involves the dehydration of methanol. Methanol is first converted to dimethyl ether by removing a molecule of water. This reaction is typically catalyzed by acidic materials such as alumina or zeolites. In this work, to study the physical properties of the methanol dehydration reaction, CFD modeling of the adiabatic reactor has been accomplished. The researchers showed that the use of an alumina catalyst, which has selective mechanical properties and unique surface properties, is a suitable choice as a catalyst for DME synthesis. The results of this study indicate that laboratory data such as pressure, energy, and velocity in the adiabatic reactor satisfy the reaction conditions well. Also, temperature profile diagrams with changes in temperature, pressure, and velocity show that the reaction of methanol dehydration is strongly dependent on environmental factors and presents different results under the influence of other conditions.

Fourier Transform Infrared Spectroscopy (FTIR) and chemometrics were successfully used in this research in conjunction with the Attenuated Total Reflectance (ATR) technique to determine bulberry molasses (MM) canesugar adulteration. Mulberry molasses was adultered by incorporating two fructose syrups (FS), one glucose syrup (GS), one sucrose syrup (SS), and two specific high fructose corn syrups (HFCS). Calibration sets were developed for mulberry molasses by spiking sugar syrups. The actual percentage of adulteration linked to FTIR predicted results by partial least square (PLS). The preferred spectral range was 1184-944 cm-1 for prediction of adulteration levels of F20, F30, HFCS50, HFCS55 and 1090-950 cm-1 for sucrose. This method was employed to distinguish between mulberry molasses and adulterated samples. According to the findings, the FTIR technique is an accurate and affordable method that can rapidly detect sugar adulteration in mulberry molasses.

Foreign Capital Inflows and the Real Exchange Rate in Kenya
Authors: Mabwa Catherine
Published: October 2024

Despite Kenya's efforts to attract foreign capital inflows, the country has faced challenges sustaining the inflow of foreign investments and continued surge in real exchange rate. The purpose of this empirical paper is to highlight the impact of foreign capital inflows (foreign direct investment, foreign portfolio investment and foreign remittances) on the exchange rate in Kenya from 1992 to 2022 as a sample, with a particular focus on disaggregated foreign capital inflows. The study time series methodology improves on previous research on this topic by engaging Autoregressive distributed lag (ARDL) approach that can be used to examine the short-run and long-run dynamic interactions of the variables simultaneously and is more robust for small sample size of data. The research results reveal a robust and negative association between foreign capital inflows and exchange rate in Kenya. The results show that in general, foreign capital inflows does strengthen real exchange rate. At the disaggregated level, the results show that foreign direct investment, portfolio investment and remittances are associated with exchange rate appreciation in Kenya. Therefore, government and policymakers should enhance policies geared at attracting foreign capital inflows to preserve the value of the domestic currency.

Published: October 2024

The growing utilization of inorganic fertilizers results in the depletion of a minimal quantity of essential elements, including phosphorus, nitrogen, and potassium. The residual fraction is discharged into the environment as organic waste, posing a threat to the ecosystem.The black soldier fly larvae (BSFL) have been acknowledged as a solution for the increasing problem of organic waste. BSFL provides numerous benefits, including their current use of waste material, known as frass, as an organic fertilizer. The aim of this study is to examine the fertilizing properties of frass and its effects on plant growth parameters and nutrient concentration in maize kernels when consumed. This will be compared to other cultivation methods including synthetic fertilizers, conventional compost, and no compost. Following a 90-day timeframe, a comprehensive analysis was performed to assess the growth characteristics and nutrient composition within the kennels. The results of this study indicate that frass positively affects plant growth and has a favorable blend of nutrients, as previously demonstrated by studies investigating the nutrient levels in maize. This study showcased the capacity of utilizing frass as a carrier to boost agricultural output and enhance the accessibility of particular nutrients in plants. Further investigation is required to substantiate these conclusions. The widespread use of black soldier fly larvae in the agricultural sector in poor countries, particularly in Sub-Saharan Africa, has the capacity to have a beneficial effect on integrated sustainable agriculture and the achievement of Sustainable Development Goals 2, 11, and 12.
