Double Dipping: Problems and solutions, with applications to single-cell RNA-sequencing data
Authors: Smidt Tess
Published: October 2024

Symmetry-preserving (equivariant) neural networks are extremely data-efficient and generalize well when applied to diverse domains (e.g. computer vision and atomic systems). But, are there circumstances where equivariance is too strict or otherwise undesirable? In this talk, I’ll discuss how symmetry-preserving neural networks can learn symmetry-breaking information in order to fit a dataset that may have missing information unbeknownst to the researcher. Furthermore, due to the mathematical guarantees of equivariant neural networks, these learned parameters are guaranteed to be minimally symmetry breaking. I’ll describe network architectures that can learn these symmetry-breaking parameters in two distinct settings: 1) symmetry-breaking parameters are learned for an entire dataset to capture global asymmetries in the data and 2) symmetry-breaking parameters are predicted in an equivariant manner for individual examples. Finally, I’ll demonstrate these networks on several prototypical examples and apply them to predicting structural distortions of crystalline materials.
Implications of Improper Sewage Management on Public Health: A Case Study of Kosofe Local Government Area, Lagos State
Authors:   University of Lagos, Lagos, Nigeria, Oluseyi T. , Nweke J. ,   University of Lagos, Lagos, Nigeria
Published: October 2024

Sewage management and its implications on public health remain one of the major challenges of urbanisation faced by developing countries such as Nigeria. As a member of the United Nations (UN), Nigeria is actively involved in ensuring achievement of the Sustainable Development Goals (SDGs), especially those that have direct impact on human health and liveability of dwellings in urban and periurban settlements. The sanitary state of an area is largely influenced by the waste handling practices of residents and involves measures for safe waste evacuation and disposal. This study examined sewage management in the low-income settlement of Agboyi-Ketu, Lagos State. In the sampling area, 21 streets were selected using a stratified sampling technique while 105 buildings were chosen via systematic sampling, after which copies of an interview-administered questionnaire were distributed to respondents. It was found that most of the buildings erected close to the nearby water body did not have septic tanks but had either a pit toilet or a non-functional water closet. Some residents openly defecated into the nearby stream and a number of households with septic tanks disposed their sewage in the stream through sewer pipes, thereby polluting the water. Microbiological analyses were carried out on water samples collected from the area (ground water and surface water) to ascertain their level of potability. It was observed that the underground water and surface water samples were highly contaminated with enteric microorganisms such as E.coli, Klebsiella spp, Pseudomonas spp and Saccharomyces spp, thus making such water unfit for drinking. The study therefore suggests that more efforts should be made to ensure proper sewage disposal in the area to reduce the negative environmental health impacts for which the majority of residents are responsible. If the situation is addressed, then SDG 3 will be attained, i.e., to ensure healthy lives and promote well-being for all at all ages. There will be a reduction in the spread of infectious and communicable waterborne diseases such as tuberculosis, malaria, cholera, hepatitis A, leptospirosis, and typhoid fever. It is also expected that by 2030, SDG 11—making cities inclusive, safe, resilient and sustainable—will be achieved, thereby reducing the adverse per capita environmental impact of cities by paying special attention to municipal and other forms of waste management in cities such as Lagos.
Housing Affordability in Iwo, Nigeria
Authors:   Wesley University Ondo, Ondo State, Yoade Adewale , Onifade Victor ,   University of Lagos, Lagos, Nigeria
Published: October 2024

Housing is recognized as one of the most important in humans' hierarchy of existential needs. However, access to decent, safe and sanitary housing accommodation at affordable disposal rates has been a mirage to most Nigerians especially the middle and low-income segment of the society. In line with SDG 11 which focuses on sustainable cities and communities, this study explores means of making cities safe and sustainable via access to decent and affordable housing. With a focus on Iwo in Nigeria's Osun State, the study aims to ascertain the extent of the problem as well as the challenges it poses to creating a sustainable built environment. Iwo is a typical Nigerian traditional town that has been transformed by modernity. The study utilizes a comprehensive data set containing socio-economic variables of households as well as indicators of housing characteristics including, cost, rent, size and quality. Primary and secondary data were utilized. The basic data set came from a structured questionnaire that was administered to selected residents of the study area. The systematic sampling technique was used to select buildings at intervals of every twentieth building in the nine wards into which the city was stratified. In all, 1,061 copies of the questionnaires were administered on household heads in the city. Secondary data were sourced from published sources such as the report of the survey of housing units in selected urban towns in Osun State by Osun State Ministry of Finance, journal articles, textbooks and the Internet among others. Frequency tables and percentages were used to explain the results of the study. It is suggested that the institutional framework to promote, enhance and encourage affordable housing provision should be created in the town. Findings establish that high cost of acquiring land (RII = 4.22) is the most important challenge of housing delivery while the least challenging factors affecting housing delivery is lack of critical infrastructures in urban and rural areas of the state (RII = 2.15).

Published: October 2024

Housing adequacy is critical to basic human survival, but its deficit remains a major challenge in many cities in Africa. The current global development framework Sustainable Development Goals (SDGs) refocused on the importance of adequate housing to urban sustainability. The SDGs advocate for effective governance framework to develop inclusive solutions to adequate housing. Within the contexts of SDGs 11 and 16, this study explores the Lagos Home Ownership Mortgage Scheme (Lagos HOMS) initiative through the lens of governance. Designed to intervene in vital aspects of the local housing market, the Lagos HOMS initiative targets Lagos residents' first-time homebuyers. Relying on mixed methods data sources, this study benefits from a Partnership for African Social and Governance Research (PASGR) funded research on the role of urban governance in transforming African cities, with Lagos as a case study. We analysed housing governance in Lagos focusing on the concepts of capacity, inclusiveness, accountability and contestation of the Lagos HOMS initiative within the context of sustainable development. Evidence suggests that the initiative ensured transparency and accountability but there was contestation around affordability. The study concludes that these observed policy inconsistencies led to the adoption of “rent-to-own” scheme considered to be 'affordable' and politically relevant but significantly eroded progress made by a hitherto transparent but generally criticised 'unaffordable' mortgage option. With these, we offer some policy recommendations towards achieving inclusive and sustainable housing outcomes in Lagos.

This study discusses public infrastructure in urban mass housing in Nigeria, and how it can impact Sustainable Development. The study was conducted in Owerri, Imo State, Southeast Nigeria. Four purposively selected mass housing neighbourhoods for middle income residents within Owerri metropolis were appraised for neighbourhood infrastructure namely; network and quality of access roads and drainages, availability of public services, availability of communal activity areas, and safety and security measures in place in the neighbourhoods. Case study method was used for the study. Data collection was through pictorial documentation and on-site physical appraisal. The findings of the study show that estate infrastructure where available, were inadequate, thereby detracting from the achievement of environmentally and socially sustainable neighbourhoods for the residents. The study further revealed a clear absence of an integrated housing infrastructure policy which addresses quality of housing infrastructure and its implications for social sustainability. It is therefore recommended that housing estate development in Nigeria must integrate from the beginning, basic facilities and services that will complement the individual housing units, create a sense of community, and ensure proper management and maintenance of the estates. These are considered critical to the attainment of Sustainable Cities and Communities (SDG goal 11).
Climate Resilience and Global Polyethylene Bag Pollution: Exploring Synthesis of Biodegradable Plastic Bags from Cassava (Manihot esculenta) as a Solution
Authors:   Makerere University, Uganda, Byarugaba Isaac
Published: October 2024

Plastic bags are polymers of ethylene and are used in almost every aspect of everyday life across the globe for a variety of functions. After their use and disposal, plastic bags have no end-of-life time because of their non-degradable nature, leading to environmental contamination and pollution. As a way of disposing them, thermal treatment is employed but this leads to emissions that increase the concentration of greenhouse gases in the atmosphere, eventually contributing to the climate crisis. Therefore, synthesis of biodegradable plastic bags offers an environment-friendly alternative for conventional plastic bags. A biodegradable plastic bag prototype was synthesized using renewable raw materials with lower carbon footprints. Among such materials was starch obtained from wasted cassava, glycerin and vinegar which served as plasticizers to make the bag flexible and less brittle. The use of renewable raw materials (cassava) with lower carbon footprints in the production of biodegradable plastic bags can therefore be considered as instrumental in reducing plastic bags waste contamination and pollution of the environment thereby contributing towards achieving climate-resilient cities.

Transportation entails the movement of persons and goods from one place to the other. The available transportation systems as well as their efficiency and operations are major factors contributing to the achievement of economic growth as well as access to industries and infrastructures and sustainable living conditions in a particular area. The main objective of this study was to examine the convenience, pattern and efficiency of the mobility of residents of Ijoko area of Ogun State, Nigeria. With the aid of a structured questionnaire, the available transport variables were investigated to obtain people's movement trends in the study area. The survey material (questionnaire) was distributed to two hundred and forty (240) households and recovered from two hundred and twenty-seven (227) of them. The distribution of the survey material was based on stratified random sampling, as the target group was identified, divided into smaller units and presented with copies of the questionnaire. The results obtained from the study were analysed and discussed. The study revealed that although the residents of Ijoko were facing great difficulties in accessing their households, offices or businesses, and the roads were hardly motorable, residents were unwilling to leave the area because many of them were house owners (landlords). They preferred to stay at their houses than to experience delay, congestion, unpleasant or uncomfortable rides in the course of their movements in and out of Ijoko. Furthermore, Ijoko residents preferred to limit their movements to only important and compulsory places such as work, hospital, school, market and weekly religious activities. Consequently, sustainable access to infrastructures is a prerequisite to economic growth and sustainable living and can only be achieved in the Ijoko area of Ogun State via the reconstruction of Ijoko roads and provision of road furniture such as drainages, walkways, shoulders, kerbs, as well as traffic markings, signs and streetlights.

Published: October 2024

Today, many real estate developers in Nigeria are confronted with confusing procedures for guaranteeing that acquisition of excised lands is free from encumbrances and pending disputes among landowning families' (locally referred to as 'omo onile'). Without diligent and exhaustive investigation, purchasing excised land for real estate development may be fraught with complications and uncertainties encompassing the excision process, compensation and issues of original ownership of such land. This study focuses on Igando-Oloja community of Ibeju-Lekki, Lagos State. The core question guiding the study is: How were real estate developers in the community able to address the uncertainty associated with land transactions for development? A case-study scenario was utilised, which involved interviews with Igando-Oloja community leaders and developers who have purchased land in the subject area. Three categories of developers' complicated land acquisition issues were unravelled. One is a category of developers that bought the same land that had been sold to a third party by a group of disgruntled landowning families, causing litigation and delaying development. In the second category, two developers bought excised land from members of a landowning family but not all stakeholders were represented in the payment/compensation process, thus land purchase discussions had to start anew. Finally, some developers were victims of governmental excision of already purchased lands. However, prompt out-ofcourt settlement resulted from the alternative dispute resolution mechanism deployed by the landowning families and the developers. This article thus offers insight into developers' adoption of an out-of-court resolution resilience strategy that expedites the process while protecting those involved and maximising the time value of money for developers and other parties in land transaction disputes.

Access to land remains a challenge in developing countries. This paper evaluates the effectiveness of various methods of accessing land and associated constraints in Benin City, Nigeria. Using a cross-sectional survey design, a total of 236 respondents comprising 210 household heads/owners of properties and 26 heads of practice in estate firms were sampled. Tools such as standard deviation and the relative importance index (RII) as well as factor analysis (FA) were used for data analysis. Results reveal that purchase, community allocation, and gifting are the best ways to gain access to the property in the study area. Key barriers to obtaining property are the high cost of acquisition, the uncertainty of tenure, and the difficulties in completing a land transaction. It is recommended that the city's zoning code is revised, to ensure equitable access to properties. An urgent need to address the problem of the exclusionary indigenous land-ownership syndrome is revealed. This will ameliorate the bottleneck associated with community and family land allocation.
A Critical Investigation on Housing and Musical Noise Pollution in Selected Neighborhoods in Lagos, Nigeria
Authors:   University of Lagos, Lagos, Nigeria, Olusoji Stephen
Published: October 2024

Musical noise endangers the health, well-being and peaceful coexistence of people in neighbourhoods, particularly in the urban centers. Archival materials, library sources, unstructured interviews, observation and available statistics from government and its agencies were the data sources for this study. Simple random percentile revealed the presence of uncontrolled noise pollution, which was more pronounced in the high-density areas of Lagos such as Mushin, Oshodi, Ajegunle, and Alimosho, among others, when compared with the low-density areas of Ikoyi, Victoria Island, Lekki, and Banana Island. Several factors accounted for the prevalence of musical noise pollution in the low- and high-density areas of Lagos, including level of compliance with good neighbourliness, observance of basic social ethics, decorum and comportment, and educational level. The study suggests that government should promulgate more stringent laws to curb this social malaise and prosecute individuals and organisations that breach the law. Sustained public enlightenment should be carried out by relevant government agencies, communities and the people to create awareness on the inherent dangers of loud and uncontrolled music. Emphasis is on the urgent need for urban renewal in the zoning, design and construction of residential buildings, particularly in areas regarded as slums.

Authors:   Memorial University of Newfoundland, St. John's, Canada, Oyedele Obasanjo
Published: October 2024

In developing countries, the capacity to handle life-threatening health and nutritional risks is under great threat. Studies have emphasised effective communication of food risks as a measure for motivating behavioural patterns which would correct this imbalance. This study investigates the media used for publicity of food risks, level of awareness and sensitivity of consumers, as well as stakeholders' collaboration for effective prevention and control of food risks. The mixed-method design utilised involved the distribution of 110 copies of questionnaires among consumers within Surulere Local Government in Lagos and interview sessions with representatives of food manufacturing companies, mass media and regulatory bodies. Television, radio, social media, and public messages by the National Agency for Food and Drug Administration and Control (NAFDAC) were prominent media of food risks communication; the activities of the regulators led to increase in consumers' awareness and sensitivity to food risks and their benefits. Manufacturers were found to adhere to standards in food production, storage, and distribution. There was an effective collaboration among stakeholders and leading to food safety, trust and standard maintenance, and quick information provisioning.

BACKGROUND

Both rhabdomyosarcoma (RMS) and central retinal artery occlusion (CRAO) are rare medical diseases, and their simultaneous occurrence in the same patient is extraordinarily uncommon. This study presents a comprehensive overview of the clinical manifestations, diagnostic imaging results, and therapeutic interventions of a patient with both conditions.

CASE SUMMARY

In this report, we present a 30-year-old male who presented with significant protrusion, pain and vision loss and was diagnosed with RMS in the orbit and sinus with CRAO. Following resection of the sinus and orbital mass and enucleation of the right eye, the patient experienced symptom improvement.

CONCLUSION

This article provides an in-depth analysis of the patient’s clinical manifestations, the tumor’s anatomical origin, and the etiology of CRAO. The concurrent manifestation of both RMS and CRAO is exceedingly uncommon in clinical practice.
Diabetic ulcer with cutaneous squamous cell carcinoma: A case report
Authors: Luo Yun , Li Chen-Ying , Wang Yu-Qing , Xiang Sheng-Min , Zhao Cheng
Published: October 2024

BACKGROUND

Chronic skin ulcers are a risk factor for the development of skin tumors. In patients with diabetes, chronic refractory ulcers may also contribute to higher susceptibility to skin tumors. Timely surgical removal of chronic and nonhealing diabetic foot ulcers can effectively prevent progression to squamous cell carcinoma. Such cases may be misdiagnosed owing to currently insufficient clinical evidence. However, in cases of chronic ulcer wounds, it is crucial to enhance clinical awareness regarding their potential progression into malignant lesions.

CASE SUMMARY

An 84-year-old male patient with diabetes presented with a significantly ulcerated area on his foot. The ulcer had been present to varying degrees since 1996. Between 2012 and July 2019, even after receiving treatments such as herbal medicines or heat clearance and detoxification complete healing of the wound was not achieved. In July 2020, histopathological analysis confirmed a well-differentiated cutaneous squamous cell carcinoma. After the treatments, the ulcer wound healed slowly and did not expand.

CONCLUSION

Potentially malignant lesions in chronic ulcer wounds should be identified and treated in a timely manner to prevent their progression.

Published: October 2024

This article aims to evaluate the driving forces of outsourcing strategies on the organizational performance of mobile network operators in mainland Tanzania. The objectives are to identify the driving forces of outsourcing and determine the challenges of outsourcing in telecommunication companies. The article adopted a descriptive cross-sectional survey. The selection of mobile companies is based on high market share and operation period. Findings show that customer needs for high-quality services, high-rated change in service, reduction of operational expenditure, and accessing the world’s capability are among the major driving forces for outsourcing. Dependability, loss of security, hidden costs, and selection of competent partners to mention a few are the challenges faced by telecom companies. It is noted that outsourcing enables network operators to advance their organizational performance in terms of operating cost, productivity, profitability, and market share. However, customer satisfaction suffers due to the inconsistency of the quality of service offered. Therefore, it is advised that mobile operators closely monitor outsourcing service providers to ensure that agreed service levels are met, thereby, safeguarding the reputation of the company to customers.
Rhetoric Is Dead? The Fear of Stasis Behind Post-Truth Rhetoric
Authors: Jenkins Eric S.
Published: October 2024

Why does post-truth discourse feel true? This article argues that post-truth fears the death of rhetoric, rather than truth, and traces that fear to the voluminous, rapid, and intense production of stasis on social media. Social media enable and weaponize the production of stasis, and that production generates affects more aligned with death than life (stagnation, hopelessness) that explain why post-truth feels true. These fears and their concomitant hopes constitute an affective economy also present in philosophy’s predominant images of rhetoric. Some images picture rhetoric as movement, whereas others emphasize rhetoric’s capacity to secure the status quo. Social media beckon a supplementary image—a vortex—in which rhetorical movement functions to produce standstill. This image suggests the need to consider affects generated by rhetorical processes as much as from texts. Post-truth’s affective economy also drives stasis production generally, and scholars should attend to the affective economies driving various rhetorical modes.
Vector Rhetoric: GPT’s Rhetorical Agency
Authors: Kulchar Douglas
Published: October 2024

The growing capabilities of large language models (LLMs) pose important questions for rhetorical theory and pedagogy. This article offers an overview of how LLMs like GPT work and a consideration of whether they should be considered rhetorical agents. To answer this question, the article considers structural and argumentative similarities in classical theorizations of rhetoric and the philosophy of Wilfrid Sellars. GPT’s particular method of encoding statistical patterns in language gives it some rudimentary semantics and reliably generates acceptable natural language output, so it should be considered to have a degree of rhetorical agency. But it is also badly limited by its restriction to written text, and an analysis of its interface shows that much of its rhetorical savvy is caused by the highly restricted rhetorical situation created by the ChatGPT interface.

How Do Paediatricians Manage Comfort with Uncertainty in Clinical Decision-Making
Authors: McMahon Colin J. , Spooner Muirne , Sibbald Matthew , Asoodar Maryam
Published: October 2024

Background: While healthcare practice is inherently characterised by uncertainty, there is a paucity of formal curricular training to support comfort with uncertainty (CWU) in postgraduate training. Indeed, some evidence suggests medical training inherently conflicts with CWU in emphasizing pedagogies focussing on “fixing” the problem. While referral patterns increase significantly, dealing with uncertainty has direct implications for patient referral rates and use of valuable healthcare resources.
Methods: Paediatricians in Ireland were invited to participate. Face-to-face interviews were conducted after participants watched videos of varied clinician-patient interactions.. Two researchers independently analysed the collected data using thematic analysis. Triangulation and member checking was performed to ensure validity of findings. A reflection journal documented the research journey.
Results: Thirty four paediatricians participated. Five themes were identified: the interplay between quality of information, uncertainty and decision-making, confidence in clinical assessment and first-hand patient evaluation, anxiety and fear experienced by medical professionals when dealing with complex and serious conditions, strategies employed by medical professionals in managing their own uncertainty and the impact of societal and parental expectations on medical decision-making. These are moderated by a number of factors, most significantly the child’s caregivers’ comfort with doctors reassurance (CDR). Enacted management will diverge from the consultant’s clinical plan when the caregiver’s CDR cannot be satisfactorily supported.
Discussion: Clinician CWU in the paediatric context is inextricably linked to caregiver CDR. The complexities and central importance of social context in understanding CWU has important implications for how we develop educational activities to support clinician CWU and patient/care-giver CDR. This may translate to efficient use of limited resources in healthcare settings.

percurso formativo do professor de Educação Física na Educação de Jovens e Adultos
Authors: Gonçalves Patrick da Silveira , Wittizorecki Elisandro Schultz
Published: October 2024

O presente estudo buscou compreender como o processo de construção histórica do professorado de Educação Física direciona-os para a atuação na Educação de Jovens e Adultos (EJA). Participaram da pesquisa dois professores de Educação Física da Rede Pública Municipal de Canoas, Rio Grande do Sul. Para a produção de informações, a pesquisa lançou mão de entrevistas. Entendemos que os os contextos que levam esses professores à EJA são diversos, variando entre a necessidade de cumprir a carga horária prevista para professores ingressantes e a complementação da renda defasada, demonstrando a ausência de critérios objetivos para a designação de professores a essa modalidade. Essas condições indicam um descompromisso das políticas de formação com as especificidades da EJA, impactando negativamente o desenvolvimento pedagógico nessa área. Além disso, observou-se que a intensificação do trabalho e a precarização das condições laborais contribuem para uma prática docente fragmentada e desalinhada com os princípios emancipatórios da EJA, o que pode comprometer a qualidade do ensino oferecido.

Published: October 2024

O artigo parte do diagnóstico de que a noção de colaboração se tornou central no debate sobre a formação interprofissional no campo da saúde, sem, contudo, estar adequadamente fundamentada e esclarecida em seu sentido pedagógico. Diante deste quadro, busca apresentar um fundamento pedagógico inovador para a formação de profissionais da saúde, a partir de uma leitura hermenêutica da noção de colaboração. Tendo por base uma pesquisa bibliográfica, primeiro, revisita-se a literatura sobre Educação Interprofissional em Saúde a fim de identificar nela o significado subjacente à noção de colaboração. Em seguida, recorrendo à obra de Gadamer, reconstrói-se a noção de diálogo em sentido hermenêutico. Por fim, tenta-se mostrar como a noção de diálogo em sentido hermenêutico pode oferecer novo (e inovador) sentido para a noção de colaboração, transformando-se em fundamento pedagógico para a formação e a atuação profissional em saúde. Conclui-se que há um ganho formativo na compreensão da colaboração como diálogo.

Published: October 2024

Dados coletados nos últimos seis anos pelo grupo de pesquisa Infantia revelam que, nos contextos observados, existem várias práticas envolvendo o uso de materiais como lápis e papel. Essas intervenções impactam significativamente o desenvolvimento, o aprendizado, bem como as interações sociais das crianças. Além disso, o texto examina a relação entre inovação e tecnologia, particularmente a integração de dispositivos digitais na educação infantil. No entanto, esses contextos muitas vezes ignoram como as crianças aprendem, interagem, vivenciam e constroem social y culturalmente sua compreensão da realidade. Materiais e objetos cotidianos estão amplamente ausentes das práticas educacionais na Educação Infantil brasileira, com as crianças sendo ensinadas usando métodos tipicamente projetados para ambientes de Ensino Fundamental. Os dados também destacam situações educativas envolvendo objetos cotidianos, ressaltando a importância de implementar abordagens educacionais que promovam o aprendizado e o desenvolvimento em contextos da primeira infância.

Introduction: Catamenial pneumothorax is a rare but potentially life-threatening condition that affects women of reproductive age. It is characterized by the recurrent occurrence of pneumothorax during or around the menstrual period. The pathophysiology of catamenial pneumothorax is not well understood, but is thought to be related to the presence of endometrial tissue in the pleural cavity.

Case Presentation: A 42-year-old woman was referred to our outpatient department for further thoracic surgical treatment. She already had two previous episodes of pneumothorax that occurred during her menstrual period. A chest X-ray revealed a right-sided pneumothorax and she was admitted to the hospital where a chest tube was placed to treat the pneumothorax. CT scan revealed the presence of endometrial tissue under the right diaphragm. The patient underwent a total laparoscopic hysterectomy to remove the source of endometrial tissue. The subdiaphragmatic endometrial tissue was also removed. She subsequently underwent thoracoscopic treatment to treat the pneumothorax.

Conclusion: The aim of this study was to review the clinical features, diagnostic criteria, and treatment options for catamenial pneumothorax. In addition, the study highlights the importance of a multidisciplinary approach to the management of catamenial pneumothorax, involving pulmonologists, gynecologists, and thoracic surgeons. Further studies are needed to optimize the management of this rare condition.

Este artículo propone una red de sensores inalámbricos para recolectar automáticamente datos relacionados con parámetros de agua en granjas de camarón. Una topología de malla se utilizó en la implementación de la red. Esta topología aumenta la confiabilidad de transmisión de datos. Para reducir el consumo de energía, los módulos de hardware disponibles con el modo de ahorro de energía se utilizaron. Los nodos fueron colocados en plataformas flotantes para recolectar y transmitir datos de temperatura del agua a diferentes velocidades. La red de sensores fue probada en entornos de laboratorio y campo (tanques y granjas). Los resultados obtenidos hasta la fecha son alentadores y demuestran las posibilidades de explotar hardware electrónico de bajo costo para aplicaciones de la acuicultura inteligente.

El Ecuador en los últimos años ha sido señalado como el país más emprendedor de América Latina, sin embargo, esos emprendimientos no se mantienen en el largo plazo, analizar el escenario en que se desarrollan y destacar los factores que inciden en su sustentabilidad y sostenibilidad es el objetivo del presente artículo. En cuanto a la estructura y dentro de ella la metodología empleada en el trabajo, se plantea inicialmente la revisión conceptual del emprendimiento como campo de investigación, las características del emprendedor, así como también el escenario en que se desenvuelve dada su importancia para la sostenibilidad de los emprendimientos. En cuanto a los datos utilizados, se los toma del reporte Global Entrepreneurship Monitor (GEM) 2015, quienes utilizan una metodología que les permite capturar interacciones entre individuos y entorno como son las encuestas a la población a un mínimo de 2000 adultos en edades comprendidas entre 18 y 64 años seleccionados al azar, y la opinión de expertos sobre los componentes de las Condiciones Marco Emprendedoras, a través de la Encuesta Nacional de Expertos. En la parte final se realizan las conclusiones del trabajo y se proponen algunas acciones de Administración estratégica que permitirían la sustentabilidad de los emprendimientos.

Monte Carlo Simulation of Electron Beam Induced Current in Au/Si Schottky Diodes: effects of metal layer thickness and minority carrier diffusion length
Authors: Hafsi Zoulikha , Khane Yasmina , Mansouri Khaled
Published: October 2024

The Electron Beam Induced Current (EBIC) technique, when combined with scanning electron microscopy (SEM), offers valuable insights into the electronic properties of semiconductor materials at the nanoscale. This study leverages EBIC and Monte Carlo simulations to investigate the behavior of Schottky diodes, particularly focusing on the influence of gold layer thickness on current gain and backscatter electron (BSE) yield. The simulation results reveal the significant effects of depletion depth and minority carrier diffusion length on the diode’s performance. A key finding is that the EBIC current decreases with increased gold layer thickness, due to a higher BSE fraction. Additionally, at low beam energies, the current is negligible when the interaction volume is confined within the metal layer, while at higher energies, some penetration into the semiconductor occurs, generating a measurable EBIC current. These findings provide a better understanding of the interplay between metal layer thickness and semiconductor performance, which is crucial for optimizing semiconductor devices.
Experimental investigation on the flexural performance of reinforced cold-formed steel 'C' section beams

A very interesting technical objective for the improvement of the mechanical performance of cold formed profiles is to avoid its instability or even to reduce its effect. Among the proposed solutions, the reinforcement of the section with struts offers an optimal alternative. Positioned parallel to the web and fixed to the edges of the flanges, the struts perfectly counteract local instability and delay global instability. This study is a component of an experimental and numerical strategy to determine how much of an impact this kind of reinforcement will have on the overall strength of a bent C-beam.Two profile sizes and various variants of strut reinforcement are proposed. Experimentally, the profile is progressively braced between its flanges with square pieces, the side of which is equal to the height of the web. Thus, blocking their warping, at defined spacing, one could judge the contribution of the device added to the flexural rigidity. Following a finites elements modelling (ABAQUS) andthen a characterization of the cross-section according to Eurocode 3, the article proposes a prediction model that can estimate the contribution of the struts to the flexural rigidity of these profiles. The results were encouraging, as the flexural inertia can double at certain strut spacing, with almost no change in weight.

This article reports the results of a theoretical study of the host/guest inclusion complex involving a herbicide called Diuron in β-cyclodextrin. Various computational techniques were used to determine the structure, geometry and stability energies of the complex. The analysis of the diuron/β-CD inclusion complex was performed both in vacuum and in water in a 1:1 ratio. The DFT/B97-3C method was used to obtain the structures of the complexes and to calculate their stability energies. The specific configurations were determined using nuclear magnetic resonance spectroscopy. The interaction bonds were investigated and the formation of conventional hydrogen bonds was detected by AIM analysis. The nature of the interactions was further elucidated using the method of non-covalent interactions (NCI). This showed that hydrogen bonds and van der Waals interactions contribute significantly to the formation of the inclusion complex. To gain more insight into the absorption and emission energies of the investigated complex, the gap energy (EHOMO-ELUMO) was calculated.
