Microscale And Nanoscale Testing Of Materials Using Scanning Probe Technologies
Authors:   ,   Cork Institute of Technology, Phelan Mark
Published: June 2024

Understanding solid surfaces and their properties is of crucial importance for many sectors of industry. This interest stems from the fact that solid surfaces are the working interface between a solid material and its environment and in many cases it is this interface which determines both the suitability and life span of a mechanical component. Furthermore the modification of surface properties using coatings and multi-layered materials has grown significantly, particularly in the case of data storage, optics and microelectronics. The demands of these and other sectors have provided the impetus for the development of material testing techniques applicable to coatings at the micro and nano scale. The advent of scanning probe microscopy (SPM) in the 1980s has provided an ideal platform on which the development of new material testing techniques can be based. SPM systems have surpassed conventional instruments in terms of resolution limits and are capable of measurements at the atomic scale. This thesis examines the use of SPM based techniques in the evaluation of surface properties such as roughness, hardness, wear, adhesion, adhesive force and friction. To fully investigate the feasibility of using scanning probe technologies for material testing at the microscale and nanoscale, a prototype multi-test instrument based on these principles was designed and constructed. Preliminary applications data obtained using this prototype are presented and demonstrate the potential for instruments of this type.
Acidic Marine Biotoxins Implicated In Diarrhetic Shellfish Poisoning
Authors:   ,   Cork Regional Technical College, Carmody Eoin
Published: June 2024

"An okadaic acid (OA) etiology has been demonstrated for most outbreaks of diarrhetic shellfish poisoning (DSP) in Europe, An isomer of OA, dinophysistoxin-2 (DTX-2), has recently been found in Irish waters and, in 1991 and 1994, was the major toxin during prolonged infestations in cultivated mussels (Mytilus edulis) along the south-west coast of Ireland. The OA class of DSP toxins have been analysed by HPLC using modified versions of three established fluorescent derivatisation methods. A ‘dual tag’ method for the confirmation of specific toxins has also been developed. Survey work has been carried out over the past four years on several mussel culturing areas in the south-west of Ireland. Results of seasonal, geographical, as well as horizontal and vertical variations in shellfish toxicity are reported. Evidence that there is a correlation between changes in temperature and subsequent appearance of high cell counts of Dinophysis acufa in the surface water column exists. The monitoring of oceanographic profiles may be useful in predicting future toxic events. Two commercially-available ELISA methods, designed to determine OA were examined for potential use in the analysis of samples containing both OA and DTX-2. Rapid DSP- screening of shellfish in Ireland and other European countries may thus be possible using ELISA. International collaborative studies have been undertaken on new DSP toxins, DTX-2 and DTX-2B, which have been isolated in our laboratoiy. The cytotoxic and protein phosphatase activity of DTX-2 is presented. Mass spectral data for these toxins using LC-ISP-MS, FIA-MS and negative-ion FAB MS/MS techniques is reported. Preliminary findings using ozonolysis for the detoxification of contaminated shellfish is also presented. The synthesis of a new fluorogenic reagent for the analysis of carboxylic acids by HPLC is described. The reagent was found to react readily with saturated fatty acids in aqueous solution, under mild reaction conditions. "

Development Of A New Hydroseeding Process For Soil Stabilisation And Vegetation
Authors:   ,   Regional Technical Collge Tralee, Keane Eileen
Published: June 2024

A variety of mechanical and chemical extraction procedures were used to produce crude alginate gels from 3 seaweed species. These viscous hydrocolloidal substances had excellent adhesive properties but did however prove phytotoxic to germinating seeds. Experimental gels were subsequently refined and germination trials were carried out to determine optimum gel types. Pilot field trials were set up to compare the 2 most favourable gels with existing commercial hydroseeding products imported from Norway and Sweden. These tests involved the use of experimental plots on loam and sand substrates with slopes of 0^, 22^ and 45^. A number of biodegradable organic substances were tested for suitability as mulch materials in combination with the gels. These included seaweed and sewage based composts, produced specifically for this purpose. Commercial mulches imported from the U.S.A. were used as controls. Results show that optimum germination was achieved on alginate gels produced from Ascophyllum nodosum at all gel concentrations. Gels produced from Fucus and Laminaria spp. performed satisfactorily at low concentrations but germination was significantly reduced on higher gel concentrations. The optimum mixture for turf establishment by hydroseeding was a gel produced from Ascophyiium nodosum mixed with a mulch of seaweed compost, sawdust and paper. Remaining mixtures compared favourably with the control products but did however, display some limitations for use as germination media in hydroseeding.
The Analysis And Isolation Of Diarrhetic Shellfish Poisoning Toxins
Authors:   ,   Cork Regional Technical College, Kelly Seán
Published: June 2024

"This research was initiated to examine the Diarrhetic Shellfish Poisoning (DSP) toxin profiles in mussels (Mytilus edulis) in south-west Ireland. Extensive sampling and testing of shellfish was conducted during the toxic periods of 1991 to 1994. This was the most comprehensive study ever undertaken of toxin profiles in shellfish from a single cultivation area. A new toxin named dinophysistoxin-2 (DTX-2), which is an isomer of okadaic acid (OA), was the major toxin during prolonged DSP episodes. This toxicity in shellfish occuired soon after high cell counts of Dinophysis acuta were observed. As well as seasonal variability in toxin levels, substantial variations were also observed both horizontally and vertically, within the water column. DTX-2 was isolated from mussel hepatopancreas using extensive chromatographic procedures. It was found to be a potent inhibitor of protein phosphatase and its activity is similar to that of OA. Another new compound, code-named DTXB-91, was also isolated in small quantities. This was confrrmed to be a diarrhetic toxin from its potent inhibition of protem phosphatase activity and was determined to be an isomer of okadaic acid by LC-MS/MS analysis. These potent bioactive compounds have been made available to a number of research institutes for biochemical studies of cellular reactions. The confirmation of DTX-2 in Portuguese shellfish has been made possible by the availability of toxin standard. Furthermore, reports of the presence of DTX-2 in the dinoflagellate, Prorocentrum lima, has been shown to be incorrect. Two commercially available ELISA methods and a rapid cytotoxicity test, designed to detect okadaic acid, have been evaluated for their potential use as a DSP toxin screening method for European shellfish. Four fluorescent HPLC methods, used to analyse for DSP toxins in shellfish, have been evaluated. 1-Bromoacetylpyrene (BAP) has been successfully used as a derivatising agent for the analysis of okadaic acid, DTX-1, DTX-2 and DTXB-91."
The Measurement Of Angiotensin-converting Enzyme In Human Serum
Authors:   ,   Cork Institute of Technology, Kenny Andrew
Published: June 2024

"The measurement of angiotensin converting enzyme using the substrate FAPGG was investigated with a view to optimising its performance. It was found that a 100 mnol/l triethanolamine-HCl buffer gave a significantly higher absorbance change then the existing TRIS-HCl in the method. As this buffer has not been previously described in the measurement of ACE it was decided to introduce this buffer into a kinetic procedure and evaluate the modified method. The reference interval for the triethanolamine Method was determined by measuring the ACE activity on 200 serum from blood donors and a significant difference (P < 0.05) in the SACE activity of male and female donors was observed. The modified method was found to correlate well with the existing TRIS CL assay on the Hitachi 704. The purchase by the laboratory of the Hitachi 911 provided an opportunity of running the ACE assay as a kinetic method over a longer incubation period. With the improved performance characteristics of the modified method, the possibility of detecting measurable amounts of ACE in CSF was determined but was found to be too insensitive to measure such low activity.. The potential interference by bilirubin haemoglobin and lipids was investigated. The effect therapeutic ACE inhibitors on the assay was investigated. A dose related response was seen in relation to the ACE inhibitors lisinopril and captopril was seen but inhibition of ACE by captopril was found to decrease on storage at 4°C. A sample would need to be analysed within a few hours in order to give on accurate indication of the degree of inhibition. The potential to use SACE as a bioassay of ACE inhibitors or as a test of compliance is discussed. The millimolar absorptivity of FAPGG on three instruments was evaluated, and compared with calibration as a way of measuring ace activity."

Authors: Viola Juan Bautista
Published: June 2024

Ante la extensión de discursos de odio y el ascenso de partidos de extrema derecha en la Unión Europea (UE), este artículo explora el accionar de las instituciones del proceso de integración europeo para proteger a la comunidad LGBTIQ+ puntualmente frente a lo acontecido en Hungría y Polonia. Primeramente, se analizan tanto las disparidades en el reconocimiento de derechos de las diversidades sexuales en los Estados miembros como la aceptación en la sociedad europea. Seguidamente se presentan los instrumentos jurídicos con los que la UE puede defender a las personas LGBTIQ+. Por último, se analizan las acciones que han llevado adelante tres de las instituciones de la UE, a saber, la Comisión Europea, el Parlamento Europeo y el Tribunal de Justicia de la Unión Europea. Todo esto permitirá concluir que, aun con sus limitaciones, la UE se ha constituido como un contrapeso al accionar anti-LGBTIQ+ de algunos gobiernos de extrema derecha.

Since the qubit’s performance of solid-state spin centers depends highly on the host material, spin centers using new host materials may offer new qubit applications. We investigate the optical properties of Ce-implanted MgO and MgAl2O4 as potential materials holding the optically accessible qubit. We find that the photoluminescence of Ce-implanted MgAl2O4 is more than 10 times brighter than that of Ce-implanted MgO and observe polarization-dependent emission of Ce center in MgAl2O4 with 2% at 4 K under 500 mT, suggesting that the properties required for initializing and reading the state of the spin qubit have been achieved.

Published: June 2024

In this study, we propose a strategy to construct high-performance ultra-thin optical power converters (OPCs) based on Gires–Tournois resonator configurations operating in high-order modes. Despite reducing the absorber thickness by 5.8 to 8.1 times, the proposed ultra-thin OPCs exhibit the same (comparable) energy absorption characteristic and demonstrate superior electrical performance compared to a thick OPC. It is revealed that such high absorption effects originated from the excitation of optical asymmetric Fabry–Perot-type high-order inference resonance modes and the electrical performance enhancement can be attributed to the reduction of the absorber thickness.

Published: June 2024

This study aims to determine whether the influence of entrepreneurship education and the use of social media among students affects entrepreneurial interest through entrepreneurial motivation. This type of research is quantitative research. The research design uses a survey method with a questionnaire as a data collection instrument. The study population was all Entrepreneurship Students of Universitas Negeri Makassar which amounted to 427 students. While the sampling technique uses Proportional Random Sampling technique, which is calculated using the Slovin formula with a sample size of 84 respondents or 22% of the total population. The research method used in this research is quantitative. The results showed that indirectly entrepreneurship education and the use of social media affect the interest in entrepreneurship with entrepreneurial motivation as an intervening variable. However, for the direct effect of only entrepreneurship education and the use of social media on entrepreneurial interest that has no effect, while for the effect on entrepreneurial motivation there is a significant effect. This research can be a source of information or reference for teaching staff or lecturers so that they can direct and guide students regarding the development of entrepreneurial interests, students are also expected to deepen their interest in business management so that they are not only focused on the knowledge produced, but also able to do business and develop it.

Authors: Saputra Aji , Saprudin Saprudin , Sambiri Usman
Published: June 2024

Computational Thinking is a skill that plays a significant role in improving students' skills, achievements, and global competitiveness. This research aims to determine the Computational Thinking abilities of preservice physics teachers for each indicator by creating a simulation using the Scratch application. This research is a descriptive qualitative study. The respondents involved in the research were 10 pre-service physics teachers at Khairun University. The respondents are students who have taken Computer Programming courses. The saturated sampling technique was used to determine the respondents. The data collection technique for this research is a test. The instrument used is a simple project to simulate projectile motion. The results of this research show that all students were able to complete the abstraction and generalization components perfectly. Furthermore, in the decomposition and algorithmic thinking components, two students made incorrect commands in the Scratch application. However, after the interview, it was revealed that the error was not due to their lack of understanding of physics concepts, but rather due to the limitations of mathematical operations in the Scratch application. Importantly, several students explained that most of the Computational Thinking components had already been developed through their habit of solving physics phenomena cases. Therefore, it can also be concluded that Computational Thinking can train students to solve physics problems effectively.
Establishing Inclusion for SEN in Faith-based Schools in Thailand: A Case Study
Authors: Japon Kimberly R. , Abordo Ian C.
Published: June 2024

In Thailand, research on inclusion program predominantly focused on inclusion programs in government-run schools. The need to understand specific inclusion of students with special needs (SEN) within faith-based settings cannot be neglected. This study addresses this gap by investigating the processes by which diverse faith-based schools in Thailand foster the inclusion of students with special needs. Through in-depth interviews with nine participants and observations from two faith-based schools, a case study was employed, incorporating within-case and cross-case analysis. Findings reveal that faith-based schools established inclusion models aligned to the schools’ mission statements and values. Inclusive practices were open communication, parental involvement, teachers’ collaboration, and specific inclusion strategies such as accommodation and modification, as well as celebrating diversity and inclusion. Barriers to inclusion include lack of knowledge, skills, and training in inclusion. Further research on the long-term influence of faith-based schools’ values on inclusion practices and the quality of life of SEN can enhance global understanding of faith-based approaches to inclusivity.

Published: June 2024

The urgency of using AI in the educational environment as a medium for optimizing student learning personalization in synchronous and asynchronous learning needs to be done to ensure that students experience improved attitudes, motivation, and learning satisfaction, which is reflected in student competencies. This study aimed to investigate the impact of ChatGPT use frequency on students' attitudes, satisfaction levels, and competence in higher education learning goals. The type of research employed was non-experimental quantitative research, specifically ex-post facto research. The sample size was 257 people, which was determined using the criteria of Issac and Michael (1971) and sampling distribution with a proportional random sampling technique. Data collection techniques that utilize questionnaires are effective in obtaining quantitative data. The PLS SEM analysis was used to determine the effect of exogenous latent variables on endogenous latent variables. The study revealed that reliability and satisfaction with ChatGPT positively impact learning outcomes, while the perceived impact on competence does not significantly enhance learning objectives. Increased usage frequency moderates these effects, diminishing the positive influence of perceptions, reliability, and satisfaction and shifting the impact on competence to negative and insignificant. These findings highlight the complexity of integrating ChatGPT into education, suggesting that initial positive perceptions may not be sustained with frequent use.

Authors: Hani Umi , Subhan Yan Ardian , Rasyad Himsyar
Published: June 2024

Purpose: The objective of this study is to examine the patriarchal society of Disney’s Cinderella using patriarchal analysis. Cinderella is a well know adaptation of the fairytale. Although seemingly a harmless cartoon about princess, it actually has a harmful representation of a patriarchal society.
Methodology/approach: Descriptive qualitative and library research methods were used to analyze and describe the quotations and transcripts based on the Kate Millet theory of sexual politics. 
Results/findings: From the research, two signs of patriarchal society are depicted: (1) the ideological sign where every male character in the movie thinks of women as something to be subjugated at and to be married to continue the family line. (2) Psychological signs where the female character including Cinderella is accepting their traditional role as home maker and not making any effort to escape the patriarchy
Limitations: This study depicted many signs of patriarchal society in the film, but this discussion is limited only into two clear signs of patriarchal society
Contribution: Hopefully, this analysis can contribute to the field of film, literary studies, and sociological perspectives.

Kuala Langsa merupakan kawasan padat penduduk di perairan hutan mangrove. Cemaran mikroplastik di perairan menjadi permasalahan yang cukup serius bagi organisme perairan. Penelitian ini bertujuan untuk mengetahui keberadaan jenis mikroplastik dan jenis bivalvia yang banyak mengandung mikroplastik. Penelitian ini merupakan penelitian survey dan pengambilan sampel menggunakan transek. Pengambilan sampel terbagi menjadi 2 lokasi yaitu dekat pemukiman warga dan kawasan hutan mangrove. Jenis bivalvia yang didapat yaitu kerang dara (Anadara granosa), kerang lokan (Geloina erosa) dan kerang kepah (polymesoda erosa). Pengamatan partikel mikroplastik dilakukan dengan menggunakan mikroskop stereo dilaboratorium FKIP Biologi Universitas Syahkuala. Hasil penelitian menunjukkan bahwa ketiga spesies bivalvia mengandung partikel mikroplastik yang bervariasi. Mikroplastik yang ditemukan berbentuk fragmen, Line dan film. Berdasarkan lokasi pengambilan sampel bahwa lokasi pertama yaitu dekat daerah pemukiman warga ditemukan mikroplastik sebanyak 16 partikel dari 2 spesies Bivalvia. Sedangkan lokasi kedua yaitu di daerah kawasan hutan mangrove ditemukan sebanyak 12 partikel dari 3 spesies Bivalvia. Berdasarkan perhitungan partikel mikroplastik setiap spesies bivalvia bahwa jenis kerang darah (Anadara granosa) paling banyak terakumulasi oleh mikroplastik.

Mangrove crab (Scylla paramamosain) is one of crab species that live in mangrove area. The purpose of this research was to obtain the morphometric and alometric of mangrove crab in mangrove area in santen island Banyuwangi. The sample of this research were taken by used transek methode by divide the area in to 3 stations. The first station was located in upper course of mangrove, the second station in down stream of mangrove, and the third station in the middle of mangrove zone. This research was measure about carapac length (CL), carapac width (CW), abdoment leng (AL), abdoment width (AW), hand bite length (HBL), hand bite width (HBW), frontal length (FL), and frontal width (FW). The alometric was observed about relation of morphometric measurement and bodymass in female and male of crab. The result of this research showed 3 species from all of the stations. But the focus of measurement was in one species called Scylla paramamosain. The result of male morphometric measurement minimal CL: 6,5 cm, CW: 8,5 cm, AL: 4 cm, AW: 1,5 cm, HBL: 10 cm, HBW: 1,5 cm, FL: 1 cm, FW: 2 cm, Body mass: 200 gram.
