Published: August 2024

In recent years, global climate change has become more and more obvious, and extreme rainfall weather has occurred frequently, which has a serious impact on people’s life and property safety. In order to reduce the risk of urban flooding and contribute to the sustainable development of the urban economy, society, and environment, this study takes Zhengzhou City as the study area. The surface runoff during extreme rainfall events from 2005 to 2023 was simulated using the SCS-CN model, and the spatiotemporal patterns of surface runoff during extreme rainfall conditions and their influencing factors were investigated. The results showed that (1) the average annual extreme rainfall in the study area was 95.6 mm, and the average annual surface runoff was 76.5 mm, with cultivated land contributing the most to surface runoff, accounting for more than 50%. The annual average frequency of extreme rainfall in the study area ranged from 0 to 3 times. (2) During the extreme rainfall events in 2021 and 2023, the surface runoff of the main urban area was relatively great. Under the influence of impermeable surfaces, the surface runoff of the main urban area was greater than that of the surrounding area, even when the rainfall in the main urban area was less than that in the surrounding urban area. In addition, during these two extreme rainfall events, the surface runoff in the slight slope (<5°) area was the greatest; overall, the larger the slope was, the smaller the surface runoff. (3) Differences between rainfall and surface runoff (DRS) of the different administrative districts in the study area showed three trends from 2005 to 2020, with those of most areas showing a clear decreasing trend, which was affected mainly by the surface runoff potential of the land use type. Under the same rainfall conditions (110 mm), the surface runoff of urban land and construction land was 1.4–2.5 times that of various types of woodland and grassland. From 2005 to 2020, the area of urban land and other construction land increased by 104.13%, the coverage area of woodland and grassland decreased by 35.90%, and the surface runoff potential increased in most areas of the study area. To reduce the risk of urban waterlogging, most areas of Zhengzhou, especially the main urban area and slight slope areas, need to rationally regulate land use and increase the coverage ratio of woodland and grassland.

Published: August 2024

Schools provide strategic resources for urban sustainability. An international, interdisciplinary research agenda documents the social and ecological benefits of living in green or re-naturalised schoolyards, a hybrid format of urban nature-based solutions. Focussing on low- and middle-income countries, where implementation lags, this paper addresses the challenges of replicating and scaling successful pilots. A better understanding of capacity building challenges is crucial, considering that schools face several concurrent challenges, including historical preservation of heritage buildings, universal access provision, and infrastructure failure in ageing facilities. This study presents primary evidence from action research to build and promote living schoolyards in Argentina, structured as a comparative case study of attempts to co-develop yards with two schools in Buenos Aires. One was an older school with historical preservation status; the other was a more modern, larger school with relative heritage value. Findings show contrastive outcomes. Our programme advanced only in the former. Historical preservation regulations posed relatively manageable contingencies, whereas insurmountable obstacles came from poor general maintenance and governmental risk aversion. Concluding remarks make suggestions on how to co-design projects with communities to synergise heritage schemes, creatively fix infrastructure deficits, and stir a mindset shift for decision-makers to understand and value urban re-greening.
Perforated and Composite Beam and Arch Design Optimization during Asymmetric Post-Buckling Deformation
Authors: Andrianov Igor , Olevskyi Viktor , Olevskyi Oleksandr , Olevska Yuliia
Published: August 2024

The structural elements of buildings have recently required the development of efficient design solutions due to increased dynamic and thermal loads. The main solution for improving the efficiency of such elements involves creating lightweight non-uniform beam and arch structures from alloyed steel, which has better mechanical characteristics. The most promising approach is the use of welded beams and arches with perforated partitions and composite beams, which are often used together, for instance, as structural elements of cylindrical shells. The development of an effective cross-sectional shape for perforated beams and crane girders is considered, taking into account the strength, local stability, resistance to flat bending, and fatigue deformation. It has been shown that the effective form for perforated beams is a box-shaped structure made of perforated shvellers. Calculations for selecting a rational design from the assortment of hot-rolled shveller profiles have demonstrated that a significant reduction in the weight of the structure can be achieved by using the proposed cross-sectional shape. An evaluation of the fatigue strength of composite metal crane girders operating in harsh conditions has shown the effectiveness of using hot-rolled I-beams as their upper flange, as well as the necessity of using hot-rolled I-beams to ensure strength in their lower part. When choosing the rational parameters of an arch design, multiple recalculations of its bending with respect to technological cutouts in the thickness are necessary; hence, simplified calculation schemes are commonly used. Some authors simplify this process by replacing an arch with a cutout with a solid arch reduced in height by the cutout radius. We have shown that this model does not accurately describe the actual distribution of forces and displacements, leading to inadequate results. We have developed a simplified methodology for the preliminary calculation of a circular arch with a cutout, which includes correction coefficients calculated by us. A calculation of the flat stress–strain state of an elastic circular metal arch with a central semicircular cutout under various ratios of design parameters and uniform external pressure was conducted. A dependence of the stress concentration coefficient at the cutout’s apex on the ratio of the cutout radius and arch thickness was obtained. These results can be generalized for reinforced non-uniform shells and for the fuzzy application of external influences.

Published: August 2024

Antimicrobial resistance (AMR) is one of the biggest threats to human and animal health. Efforts to combat AMR include the introduction of antimicrobial drugs as alternative treatment options. To contribute to an effective plan for the treatment of infectious diseases caused by bacteria, the development of new antimicrobial agents is increasingly being explored. Propolis has garnered significant attention from both scientists and industry due to its extensive spectrum of biological activity. The growing interest in polyphenols of natural origin and their plant sources further encourages the investigation of their chemical composition and biological effects. Propolis serves as a rich source of phenolic compounds. Baltic region propolis, classified as poplar-type propolis, was selected for this study, and extracts were prepared using raw propolis materials from various Baltic countries. The production of liquid extracts utilized a combination of 70 percent ethanol, a mixture of water and poloxamer P407, and DES (deep eutectic solvent). The research aims to produce liquid propolis extracts using different solvents and to assess their chemical composition, antioxidant, and antimicrobial activity against different veterinary pathogens. Antioxidant activity was evaluated using DPPH (2,2-diphenyl-1-picrylhydrazyl), revealing antioxidant activity in all extracts, with results correlating with the total phenolic compound content. It was found that p-coumaric acid predominated in the studied propolis extracts (in ethanol extracts 1155.90–1506.65 mg/g, in DES extracts 321.13–954.76 mg/g, and in polymeric extracts 5.34–30.80 mg/g), with smaller amounts of ferulic acid and vanillin detected. Clinical and reference bacterial strains were collected from the Lithuanian University of Health Sciences, the Academy of Veterinary Medicine, and the Institute of Microbiology and Virology. To effectively treat bacterial infections, the antimicrobial activity of propolis extracts was tested against six pathogenic bacterial species and one pathogenic fungus (S. aureus, S. agalactiae, B. cereus, E. faecalis, E. coli, P. aeruginosa, and C. albicans). Antimicrobial activity studies demonstrated that DES propolis extracts exhibited stronger antimicrobial activity compared to ethanolic propolis extracts. The minimum inhibitory concentration (MIC) values of DES propolis extracts against the tested strains ranged between 50 and 1000 μg/mL. Considering the study results, it can be concluded that propolis from the Baltic region is abundant in phenolic compounds exhibiting antioxidant and antibacterial activities.

Published: August 2024

(1) Background: Bovine viral diarrhea virus (BVDV) causes calf diarrhea, bovine respiratory syndrome, and cow abortion, resulting in substantial economic losses in the cattle industry. Owing to its persistent infection mechanism, BVDV is a major challenge in the treatment of cattle. (2) Methods: To determine how metformin (Met) inhibits the interaction between BVDV and host cells, we treated BVDV-infected cells with Met. We then performed an RNA sequencing (RNA-seq) analysis of Met-treated cells infected with BVDV to identify differentially expressed genes (DEGs). Consequently, the RNA-seq results were validated through real-time quantitative PCR (qPCR). (3) Results: Our analysis revealed 3169 DEGs in the Met-treated cells (Met group) vs. the negative controls (NC group) and 2510 DEGs in the BVDV-infected cells after pretreatment with Met (MetBVDV group) vs. the BVDV-infected cells (BVDV group). The DEGs were involved in MDBK interactions during BVDV infection, as indicated by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses. The potential interactions of the DEGs were confirmed via a protein–protein interaction (PPI) network. Met treatment induced autophagy signaling activity and the expression of the autophagy-related genes ATG2A, ATG4B, ATG10, and ATG12 in BVDV-infected Met-pretreated cells. (4) Conclusions: We found that the host transcriptomic profile was affected by BVDV infection and Met pretreatment. These findings offer valuable new insights and provide support for future studies on the inhibition of BVDV replication by Met.
Source-Oriented Health Risks and Distribution of BTEXS in Urban Shallow Lake Sediment: Application of the Positive Matrix Factorization Model

Published: August 2024

The degradation of sediments in urban environments worldwide is driven by population growth, urbanization, and industrialization, highlighting the need for thorough quality assessment and management strategies. As a result of these anthropogenic activities, benzene, toluene, ethylbenzene, xylenes, and styrene (BTEXS) are persistently released into the environment, polluting sediment. This study employed self-organizing maps (SOMs), positive matrix factorization (PMF), and Monte Carlo simulation of source-oriented health risks to comprehensively investigate sediment in an urban shallow lake in a mid-sized city in central Serbia. The results indicated a mean ∑BTEXS concentration of 225 µg/kg, with toluene as the dominant congener, followed by m,p-xylene, benzene, ethylbenzene, o-xylene, and styrene. Three contamination sources were identified: waste solvents and plastic waste due to intensive recreational activities, and vehicle exhaust from heavy traffic surrounding the lake. Both non-carcinogenic and carcinogenic health risks were below the permissible limits. However, children were more susceptible to health risks. Benzene from vehicle exhaust is the most responsible for non-carcinogenic and carcinogenic health risks in both population groups. The results of this study can help researchers to find a suitable perspective on the dynamics and impacts of BTEXS in lake sediments.

Published: August 2024

This research studies the morphology and morphometry traits of Aseel chickens raised in various regions of Türkiye. We used Turkish Aseel genotypes to assess the live weight and physical features of 60 female and 58 male subjects of varying ages. We measured brood length, breadth, head and beak width, neck and body length, chest width, depth, and circumference, thigh diameter, length, and depth, and leg length. Males' average live weight, chest circumference, thigh length, and comb length, which affect game efficacy, are 3.23 kg, 37.88 cm, 20.69 cm, and 40.20 mm, respectively. Although there was a statistically significant difference between the gender groups for all evaluated characteristics, there was only a statistically significant difference between the age groups for head width and chest circumference, shank depth, diameter, and length, and live weight (P<0.05). The data showed differences among different areas, particularly about the measurements of the comb, prompting researchers to propose a hypothesis suggesting a potential correlation between these changes and regional temperature disparities. We evaluated Turkish Aseels for feather, comb, eye color, markings, and comb type. Medium-weight breeds with hair, earlobes, beards, and spurs Weight and characteristics determine the Turkish Aseel breed. Comb structures were shorter, and their live weight was lower than that of other game roosters or Aseel kinds. Based on their morphology, domestic Aseel males may have a distinct genotype and subtype. Evaluating morphometric characteristics is an important aspect of the research. However, conducting additional comparative research is crucial. Genotyping studies with larger numbers are necessary for greater accuracy.

INTRODUÇÃO: A gestação promove uma série de alterações fisiológicas no aparelho cardiovascular, as quais podem descompensar doenças cardíacas preexistentes ou manifestar novas doenças antes desconhecidas. A insuficiência cardíaca (IC) é a complicação mais comum entre gestantes com doenças cardíacas, com potencial de causar repercussões para a mãe e o bebê. OBJETIVO: Avaliar as repercussões da insuficiência cardíaca na gravidez e a existência de fatores de risco associados. METODOLOGIA: Trata-se de uma revisão integrativa na base de dados PUBMED utilizando os descritores “PREGNANCY AND HEART FAILURE” para artigos publicados entre 2019 e 2024. RESULTADOS: Estudos revisionais afirmam que um histórico hipertensivo na gravidez está somado a um risco aproximadamente 2 vezes maior para uma doença cardiovascular. Em uma análise de coorte transversal prospectiva verificou-se que 22% dos partos sofrem interferência de condições cardiometabólicas, essas, somadas ao aumento da idade média materna aumentam consideravelmente os desfechos cardiovasculares graves. Tais fenômenos se explicam pelo alto nível de estresse fisiológico e hemodinâmico ao qual o organismo feminino é submetido. No que tange à prevenção de danos nesses casos, é necessário o acompanhamento com uma equipe multidisciplinar desde o início da gestação. Os DIUs compõem a indicação de método contraceptivo nesses casos. CONCLUSÃO: Mulheres grávidas com cardiomiopatias estão associadas a maiores taxas de incidência de distúrbios hipertensivos, diabetes gestacional, restrição do crescimento intrauterino fetal, parto prematuro e internações em UTIs. Além disso, as gestantes com IC possuem uma maior taxa de mortalidade hospitalar do que na população em geral.

Integrative and Complementary Practices (ICPs) are therapeutic approaches that integrate traditional and complementary methods with conventional ones, promoting comprehensive and humanized care, recognized and regulated by the Unified Health System (UHS) in Brazil. This study aimed to conduct a literature review on ICPs, reporting the services offered by the municipality of Juiz de Fora, MG, Brazil. Sources included clinical trials, cohort studies, systematic reviews, full articles, official documents, legislation, theses, dissertations, and others. It was observed that ICPs provide benefits in health promotion and disease prevention through less invasive and more natural methods, reducing costs and contributing to overall well-being, as they consider the human being holistically, addressing physical, emotional, and spiritual needs. In this context, the Ministry of Health has already formalized 30 practices, highlighting phytotherapy, acupuncture, homeopathy, anthroposophic medicine, chiropractic, osteopathy, and massage therapy, among others, which allow the participation of various professionals as these are non-exclusive activities. ICPs encompass different knowledge and therapeutic care approaches, involving beliefs about health, disease, and healing, and various ways of coping with illnesses. In Juiz de Fora, MG, the municipality offers services in addition to phytotherapy, including acupuncture, anthroposophy, meditation, Reiki, and homeopathy. Therefore, ICPs represent an important strategy for promoting health and well-being, offering effective and humanized therapeutic alternatives, valuing prevention and treatment of diseases holistically, promoting comprehensive care, and improving the population's quality of life.

Published: August 2024

Introdução: A obesidade caracteriza uma epidemia em todo o mundo, e a cirurgia bariátrica é considerada o tratamento mais efetivo a longo prazo para obesidade grave, em comparação ao tratamento clínico. As duas técnicas bariátricas mais realizadas são o Bypass e o Sleeve. Várias questões devem ser avaliadas quando se trata na escolha do método de cirurgia bariátrica. Objetivo: O objetivo deste estudo é evidenciar vantagens e desvantagens de cada um destes métodos, a fim de basear a discussão para a melhor escolha para cada paciente. Métodos: Este estudo configura uma revisão de literatura, baseada em artigos científicos de maior importância. Discussão: o Sleeve ganhou popularidade rapidamente, e, em 2014, se tornou o procedimento bariátrico mais realizado no mundo, porém possui suas contraindicações. O Bypass ainda é considerado padrão ouro, uma vez que induz uma maior perda de peso a longo termo em comparação ao Sleeve, mas também possui suas desvantagens. Independentemente do procedimento escolhido, o paciente pode esperar um reganho fisiológico do peso com o passar do tempo, que se inicia geralmente após dois anos do procedimento, o que não caracteriza uma falha do tratamento. Conclusão:  Não existe o melhor procedimento para todos os pacientes. Deve-se entender os riscos e benefícios de cada um dos métodos, além das contraindicações de cada um. Portanto, a escolha do procedimento a ser realizado deve ser baseada em pilares científicos e sociais, sendo sempre individualizado para cada paciente.

Five new species of Aiouea Aubl. (Lauraceae) are described and illustrated: A. acuminata van der Werff & Penagos, A. acutifolia Penagos & van der Werff, A. intermedia Penagos & van der Werff, A. pelykiflora Penagos & van der Werff, and A. pubescens Penagos & van der Werff. Aiouea acuminata resembles Nectandra hypoleuca Hammel, which differs in having six 2-locular and three 4-locular stamens and in its distribution. Aiouea acutifolia differs from the related A. laevis (Mart.) Kosterm. in having nine fertile stamens (vs. six in A. laevis) and in its broader leaves (4.5–11 vs. 3.5–6 cm). Flowers of A. intermedia are unique in having nine 2-locular stamens, with some stamens retaining one or two upper vestigial sterile locules, and coriaceous leaves with domatia as tufts of hairs in the axils of secondary veins. Aiouea pelykiflora has flowers with tepals incurved, giving flowers a campanulate shape. Aiouea pubescens has flowers with six fertile stamens and domatia as tufts of hairs in the axils of midrib and secondary veins. The different concepts of Aiouea, Aiouea sensu Renner and Aiouea sensu Rohde et al., are discussed.

The taxonomy of Calyceraceae, a small family of angiosperms endemic to southern South America and sister of Asteraceae, has recently been revised based on molecular phylogenetic analyses and the evolution of flower morphology. Despite the efforts for precision by those authors, some further nomenclatural adjustments to the classification previously provided are needed: Boopis Juss. is applied as the correct name for the “Pilose group,” and Xiphodesma Pozner & Zijlstra is a new genus name published to accommodate B. anthemoides Juss. In addition, lectotypes are designated for four names: Anomocarpus tenuis Miers, B. anthemoides var. subscandens Speg., B. leucanthema Poepp. ex Less., and B. pusilla Phil.

Published: August 2024

"The pervaporation process is investigated in this work under the guises of process design improvements and process performance. Several avenues of research were investigated. The main aim of the project was to investigate the use of liquid ring vacuum pumps for permeate recovery at laboratory and industrial scales. Due to technical and economical issues, these pumps were deemed unsuitable. This analysis then had to be extended further. Previous work investigated the use of dry vacuum pump systems on a lab scale and this work was extended to industrial scale simulations. Results from the lab scale process particularly those relating to pump lifetime were also considered. Elsewhere steam jet ejectors were previously considered and this analysis was also expanded upon. No immediate option for Improvement in permeate recovery was found. Research in vacuum technology was then considered to ascertain future possibilities. The next aim was to extend the work of a previous project. This work developed a model for prediction the flux In a PV system without the need for experimentation. The use of dimensionless numbers offered a way to possibly improve the prediction of this model. These attempts to predict the mass transfer in the boundary layers adjacent to the membrane. However Instead of modelling the boundary layers, it was decided to Investigate possible methods for destroying these layers. This was deemed to be more beneficial due to the possible increases in performance and lack of promise for the pre-existing approach. Module design Is a key element in this strategy. Several modules were proposed for further research as well as a strategy for testing these modules. The final two areas determine the effect of permeate pressure and performance indicators (flux and selectivity) on PV performance. In permeate pressure a previous classification system developed elsewhere was tested and simplified."
Enhanced Vacuum Drying Through Improved Solvent Recovery, Reduced Process Cycle Times And Prediction Of Drying Duration
Authors:   ,   Cork Institute of Technology, Mesa Delgado Diana
Published: August 2024

"Drying of pharmaceuticals and fine chemicals is often accomplished under vacuum conditions to enhance energy efficiency and to avoid overheating of thermo sensitive materials. This project aims to study vacuum drying operations to obtain a better understanding of this process so as to optimize drying performance. This project obtained industrial data collected from a range companies in Ireland. Pharmaceutical companies started assessing processes and making changes to drying processes from 2004 onwards; these initiatives are due to economic pressures, environmental issues and the Process Analytical Technology (PAT) initiative launched by the FDA in 2004. Vacuum drying has been used in industry for at least eight decades. Apart from control systems, little other significant research has been published during the past thirty years. There is a lack of published information on practical issues; this is particularly marked in the pharmaceutical industry, probably due to the constraints of FDA regulations. This study presents a description of the different vacuum drying configurations and equipment currently in use in industry. Solvent recovery rates, disposal and destination of the solvent evaporated from vacuum dryers are also assessed. Drying curves from industrial dryers are studied for a variety of products. This research also reviews relevant instrumentation and techniques for monitoring operations and for end point determination, including moisture content analysis and inferential measurements. Miscellaneous issues have been identified in industrial vacuum drying such as sampling, balling, solvent boiling, formation of solvent pockets, puffing of product and dryer cleaning. Industry uses a variety of methods for end-point determination so as to reduce energy consumption and increase efficiency. This project concludes that there are many opportunities to enhance vacuum drying operations and the dissemination of practical information is a necessity as no standard procedures are in place. This area warrants further research as many gaps have been identified during this study. This project is funded by the Environmental Protection Agency (EPA) under the Environmental Technologies Masters Scholarship Programme."
The Application Of Viral Marketing To The Irish Film Industry
Authors:   ,   Cork Institute of Technology, O'Mahony Stephen
Published: August 2024

"The research examines the concept of viral marketing and in particular, its application to the Irish film industry. It explores the merits of viral marketing as a promotional technique for Irish film and the associated online social media channels through which viral messages are disseminated. Further to this, the study identifies the extent to which viral marketing and online social media have been adopted by Irish consumers and enterprise. Given that viral marketing is still in its relative infancy, the research also takes a conceptual approach so that it contributes to the continued understanding of the practice in general. A number of findings are derived from the depth interviews which took place with industry experts. While viral marketing is growing in popularity and prominence, the research concludes that ambiguity and a general lack of knowledge still surrounds many aspects of the concept. Further academic research is needed in the area to resolve these issues so that viral marketing can overcome its apparent stigma, which has thus far stunted its universal adoption. Despite these discrepancies, however, respondents to the research enthusiastically discussed the merits of viral marketing when used properly. In an Irish context, there was unanimity in the belief that Irish commercial entities are collectively far behind Irish consumers in terms of their adoption of online social media, and in their receptiveness to viral marketing campaigns. Research on the Irish film industry concludes that filmmakers should explore these avenues of promotion, indicated by a number of findings. Film as a medium is found to be naturally suited to viral promotion; furthermore, the research finds that Irish consumers are enthusiastic adopters of online media in general, relevant to research on the indigenous film industry. Finally, the pioneering Storyland initiative by national broadcaster Raidio Teilifis Eireann is discussed as a significant development in the area, as it demonstrates the receptiveness of the Irish public to promotion via online media. The research contributes to the growing body of literature on the area of viral marketing, which strives to further develop and understand this enigmatic concept. Moreover, it helps to bridge the gap in literature that exists which examines the concept in an Irish context."

Authors:   ,   Cork Institute of Technology, McCarthy Suzanne
Published: August 2024

The purpose of this thesis is to analyse how the HSE South handled the Swine Flu pandemic. This was largely focused on how the HSE communicated with their publics as well as how they carried out such a large public information campaign. It is also important to understand how the public felt about the management of this pandemic. This thesis was dependant on interviewing various individuals from relevant backgrounds. This included PR and communication personnel employed by the HSE, representative of the media and health care professionals who deal directly with different communities within the general public. The objectives of this thesis are to establish how the HSE carried out such a large public infonnation campaign, in relation to the swine flu pandemic and to investigate how the HSE not only communicated with their publics but also how effective those methods of communication used were. It also aims to analyse how the HSE handled the pandemic in regards to their efforts made in addressing the pandemic and to examine the overall opinions of interviewees. To conclude this thesis will portray how communication methods are practised in the health care sector. It will analyse the HSE’s ability to deal with pandemics, which are liable to occur at any time, and how the HSE informed their publics in relation to these pandemics. Whilst investigating the HlNl pandemic in particular it was found that the HSE had dealt with this pandemic in a much more organised and detailed fashion than had been acknowledged by the media. The author also makes recommendations based on the research carried out and literature studied. One of the primary recommendations involves the use of social media tools in such pandemics.

Published: August 2024

"This study presents an account of practice-based educational research that was conducted during three half-year cycles between 2008 and 2010 in the CIT Cork School of Music (CSM) piano laboratories with Junior piano pupils and their teachers as participants. The study sought to explore teaching approaches in the PianoLab classes and to evaluate interlinking resources for young pianists in the context of their wider music education. In line with action-oriented qualitative methods, the first cycle involved preliminary data gathering, through questionnaires and interviews, from musicianship and piano teachers on topics related to teaching materials. Subsequently, a Focus Group was set up to facilitate interaction on curriculum planning for the PianoLab. During the second cycle, materials were evaluated by teachers and pupils. This data was included in a Course Portfolio, in which a course unit was designed, enacted and realised. A Teaching for Understanding (TfU) framework incorporating a constructivist theory of learning was used as a pedagogical approach. In collaboration with PianoLab teachers, feedback from course evaluation was gathered from other CIT Cork School of Music teachers, students and parents. Findings from these qualitative data, interpreted thematically, suggested that the TfU instructional design developed qualitative aspects of student work in the early stages of the acquisition of new skills, and that participation in the ensemble music-making aspect of the PianoLab programme had provided an impetus for learning during this acquisition.

Influence Of Coulomb Interactions On Emission Dynamics In Semiconductor Quantum Dot Systems
Authors:   ,   Cork Institute of Technology, Gradkowski Kamil
Published: August 2024

"In this thesis the novel self-assembled quantum dots based on GaSb/GaAs technology are investigated for the possible application in the near- and mid-infrared, i.e. telecommunication networks, solar cells, gas sensors and imaging systems. These heterostructures exhibit a type-Il band alignment, which means that one species of carriers is confined to the dot, while the other is outside in the surrounding matrix. This physical separation of carriers leads to profound Coulomb interactions, which makes the optical properties of these structures dependent on the injected charge density. The relationship between two of those properties, the emission energy and transition probability, leads to an intricate and complex emission dynamic. The mechanism responsible for this behavior is investigated by employing experimental and theoretical techniques on several structures that provide diverse confinement scenarios, i.e. where the electrons are confined in the dot and holes are outside as well as an alternate situation. The experiment is based on time-resolved photo- luminescence, which allows for a simultaneous observation of spectral and temporal evolution of the emission. The results are then corroborated with a self-consistent model based on an 8-band k-p formalism, which provides an explanation for the observable features. For comparison, a novel type-I InAs/GaAs quantum dot system design based on a tunnel injection scheme is investigated under a high-excitation regime, where it also exhibits an interesting emission dynamics that involves an inhibition of the optical transition probability in a charged quantum dot."
Assessing The Impact Of Social Media On The Celebrity Industry: A Public Relations Perspective
Authors:   ,   Cork Institute of Technology, O'Sullivan Jessica
Published: August 2024

"There has been an increased interest from academics, public relations professionals and industry professionals in the importance of social media in the role of public relations. This study aims to contribute to the understanding of the effect social media has on the celebrity industry, from a public relations perspective. A qualitative research design was chosen, and the primary methods used to gather the data were semi-structured interviews with online communication professionals from the public relations industry and an online music producer who uses various forms of social media to distribute and promote his music. All interviewees were chosen due to their insight and knowledge pertaining to the topic. The interviews are supported with a focus group where participants were chosen due to their knowledge and their exposure, as consumers, to celebrities and social media. The research findings show how social media is changing the role of PR in relation to the celebrity industry. Through the research process, the author learned of the exposure that arises for celebrities from embracing social media, and also the benefits of social media for the PR industry. It can be concluded that there are both advantages and disadvantages to these industries adopting social media; and while some have progressed to implement it successfully, many PR practitioners as well as celebrities are in the process of learning how to practice social media activities to the best effect. Both industries are experimenting with the platfomis of social media, and those who are tuned in and observing this new phenomenon are beginning to reap the rewards."
Induction of Callusogenesis and Indirect Morphogenesis in the Populus deltoides Marshall × Populus alba L. Hybrid in vitro
Authors: Фоменко Н.Г. , Жолобова О.О.
Published: August 2024

Виды и гибриды Populus часто используются в качестве модельных объектов в биотехнологии и селекции лесных деревьев, а также активно применяются в защитном лесоразведении, благодаря таким качествам как быстрые темпы роста и хорошая адаптация к условиям деградированных почв. Культура растительных клеток и тканей может использоваться в качестве инструмента для селекции растений путем разработки стратегий отбора сомаклональных вариаций и устойчивых к стресс-факторам генотипов. В статье представлены результаты исследования по индукции каллусогенеза и непрямого морфогенеза у гибрида Populus deltoides Marshall × Populus albaL. (Populus F1). В качестве первичных эксплантов использовали листовые сегменты и побеги растений, выращенных в культуре in vitro. Индукцию каллусогенеза осуществляли на питательной среде Murashige и Scoog (MS), дополненную синтетическим ауксином 2,4-Д либо цитокинином ТДЗ в пяти концентрациях 0,5-2,5 мг/л с интервалом 0,5. Активная индукция и формирование компактного первичного каллуса были достигнуты при невысоких концентрациях (0,5-1 мг/л) ТДЗ на листовых эксплантах. Для остановки ростовых процессов каллусной культуры и формирования морфогенных зон в качестве стресс-фактора использовали 20 г/л полиэтиленгликоля 6000, с последующим переносом трансплантов каллуса на питательную среду MS для непрямой регенерации побегов. Полученные регенеранты активно росли и укоренялись после их отделения от каллуса и переноса на свежую питательную среду. По результатам проведенного исследования разработан простой и эффективный протокол регенерации гибрида Populus F1 путем непрямого морфогенеза из каллусных тканей в культуре in vitro.

En 1907, James Ramsay Hunt identificó un nuevo síndrome caracterizado por erupciones vesiculares en la región auricular y/o mucosa oral, acompañadas de afectaciones neurológicas en nervios craneales. Este síndrome, causado por la reactivación del virus de la varicela-zóster (VVZ), principalmente afecta al nervio facial, provocando parálisis facial periférica y síntomas adicionales como hipoacusia, náuseas, vértigo y nistagmos. El SRH muestra una mayor prevalencia en pacientes inmunodeprimidos y su incidencia aumenta con la edad, siendo más común en mayores de 60 años y poco frecuente en niños menores de 6 años. Se lleva a cabo una revisión bibliográfica exhaustiva para explorar el papel crucial de los enfermeros en el diagnóstico y tratamiento del SRH. Se analiza cómo los enfermeros facilitan la identificación temprana de síntomas, manejan cuidados especializados y educan tanto a pacientes como cuidadores sobre la naturaleza y manejo del síndrome
