Hierarchical modelling of volatility spillovers in ship demolition markets
Authors: Açik Abdullah
Published: April 2024

he offered demolition prices are as important as the freight rates in the market in shipowners' decisions to send their ships for demolition. This study aims to determine the most affected and the most affecting countries in the ship demolition market by examining the hierarchical price movements among the prices offered for demolition in major centres around the world. In this direction, integrated causality in variance, Interpretative Structural Modeling (ISM) and MICMAC (Matrices d’Impacts cross-multiplication appliqúe a classmate) analysis are used. According to the obtained results, the price dependence on Turkey is the lowest, while the price dependence in Bangladesh is the highest. Volatility in the market is spreading to other markets from Turkey. These results are thought to be useful in understanding price behaviour in the ship demolition industry, which is a relatively small market.

Authors: Belotserkovsky Marat , Grigorchik Aleksandr , Kukareko Vladimir
Published: April 2024

he structural-phase state and wear resistance of coatings from high-chromium AISI 420 and A756 steels obtained by hypersonic metallisation (HM) were studied. It has been shown that coatings from martensitic steels after deposition contain an increased amount of metastable austenitic phase. In particular, 15 vol.% γ-faze is registered in a AISI 420 steel coating, and 70 vol.% γ-faze in a A756 steel coating. It has been established that during friction of hypersonic metallisation coatings of high-chromium steels, deformation-activated γ→α transformation in their surface layers leads to a significant increase in microhardness and the wear resistance of coatings.
Quality costs in catering
Authors: Malinowska Ewa
Published: April 2024

One of the tools for improving quality in an organisation is the use of quality cost accounting, which can be helpful in the analysis of the qualitative situation of an enterprise and its optimisation. There is no universal model of quality cost accounting. An organisation that decides to implement such an instrument must keep in mind that it is a time-consuming and labour-intensive process. This article presents an example of identification and quantification of quality costs for the catering industry. A presentation of quality costs was made with a division into cost groups: compliance and non-compliance and a method of recording quality costs characteristic of catering production was proposed as well as methods of their analysis and optimisation. The possibility of the use of this tool by large chains operating in the catering industry to identify the strengths and weaknesses of pro-quality activities was highlighted.

Impact of voltage subharmonics and interharmonics on currents in single-phase induction motors
Authors: Pepliński Marcin
Published: April 2024

In very low power drives, a single-phase induction motor is used. This motor, like the 3-phase induction squirrel-cage motor, requires a voltage supply with suitable parameters – of suitable quality, in practice. In energy systems, voltage quality distortions may occur in connection with the deviation of the RMS voltage and the occurrence of harmonics, subharmonics and interharmonics in its waveforms. Subharmonics and interharmonics in the voltage waveforms are particularly detrimental to induction motors. They cause, for example, additional power losses, electromagnetic torque pulsation and motor vibrations. It should be stressed that the existing publications on the impact of the considered distortions on the induction squirrel-cage motor are almost only applicable to 3-phase machines. The article presents the results of research on the influence of subharmonic and interharmonic voltage components on the single-phase induction squirrel-cage motor.

Authors: Chmielewski Mariusz , Malinowska Ewa
Published: April 2024

The aim of this paper is to present suggestions for optimisation of the process of meal preparation in schools, which would lead to a reduction in the operating costs of the facility and more effective use of the resources in question. As a result of the research it was found that in the organisation studied there exists a real possibility of staffing reductions from 4 to 3.5 full-time jobs, which would directly translate into a reduction in the costs related to running an institutional catering establishment. The schedule prepared also enabled determining the shortest possible time of performing the entire meal preparation process, which also constitutes the critical path.
A Few Remarks on the Energy Transfer Analyses During a Time Less than Period T for Voltage and Current Waveforms in Electrical Circuits
Authors: Hartman Marek T.
Published: April 2024

According to the definition the effective value of voltage V is equal to Vrms as to the mean value of u(t) during the energy transfer time T or kT, where k may be 1, 2, 3, 4 etc. However, in power electronics circuits (e.g. rectifiers, choppers, converters, inverters) the energy transfer time, Δt, in many situations is less than the functions period, T (Δt < T). In such a situation the author asks a question – how can we calculate the effective value of voltage V?
Electric Fields in the Vicinity of High-Voltage Power Lines, Optimisation of Power Line Design
Authors: Kostyszyn Roman , Miśków Dominik
Published: April 2024

This paper presents calculations in the distribution of the electrical fields generated by the potential of phase conductors in overhead high-voltage power lines. The calculations relate to the area between the line paths and the terrain, with particular focus on the area near the ground, which is important in terms of any humans present there, temporarily or permanently. Field intensity distribution is determined for different arrangements of phase conductors and line paths, and for different tower designs. The optimisation criterion is the width of the area excluded from residential development, defined as double the distance from the axis of the line where the electrical field strength exceeds the regulatory permitted 1 kV/m value.

Synthesis, Structure, Thermal Properties and Reactivity Studies on Manganese Amidinates and ß-Ketoiminates Supported by DFT: Potential Precursors for Vapor Deposition of Mn-Based Thin Films
Authors: Wilken Martin , Muriqi Arbresha , Krusenbaum Annika , Nolan Michael , Devi Anjana
Published: April 2024

To identify Mn based organometallic compounds that serve as precursors for chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes, systematic synthetic approaches with ligand variation, detailed characterization and theoretical input from density functional theory (DFT) studies were adopted. In this context, a series of new homoleptic all-nitrogen and mixed oxygen/nitrogen-coordinated Mn(II) complexes bearing the acetamidinate, formamidinate, guanidinate and ß-ketoiminate ligands have been successfully synthesized for the first time. The compounds were thoroughly characterized by single crystal X-ray diffraction, Evans NMR, mass spectrometry and elemental analysis. To evaluate their potential use as precursors for Mn-based materials, the thermal properties were investigated in detail. The specific choice of these ligand classes with changes in structure and coordination sphere and side chain variations result in significant structural differences whereby mononuclear and dinuclear complexes are formed. This was supported by density functional theory (DFT) studies. The most promising Mn(II) compounds in terms of the thermal properties, namely Bis(N,N´-ditertbutylformamidinato)manganese(II) and Bis(4-(isopropylamino)pent-3-en-2-onato)manganese(II) were used in reactivity studies with DFT to explore their interaction with oxidizing co-reactants such as oxygen and water which are relevant for CVD and ALD process development.

Authors: Iqbal Fatima , Upadhyay Astha , Tehrani Rouzbeh , Rowles Lewis
Published: April 2024

The increasing environmental concerns associated with petroleum-based ion exchange resins have spurred interest in sustainable alternatives, such as biopolymeric beads derived from chitosan. This study evaluated the sustainability of three porous chitosan particles synthesized with low-toxicity solvents (methylpentane porous chitosan particles, azocarboxamide porous chitosan particles, and tween porous chitosan particles) using techno-economic analysis and life cycle assessment. The results, normalized to both mass of particles produced and percent removal of methylene blue, revealed that azocarboxamide porous chitosan particles were the most cost-effective variant, despite the methylpentane ones exhibiting the highest removal efficiency. Environmental impacts were consistent across most categories, with azocarboxamide porous chitosan particles showing higher impacts for human toxicity (carcinogenic) and ozone depletion potential. Sensitivity analysis identified precursor costs, synthesis yield, chitosan and NaOH amounts, and electrical energy consumption as key drivers of sustainability. The findings emphasize the importance of considering both synthesis yield and treatment efficacy when evaluating the sustainability of chitosan-based ion exchange resins. Process optimization and exploration of eco-friendly alternatives are recommended to enhance the sustainability of these materials. This study contributes to the development of sustainable water treatment methods and promotes the transition towards a circular economy in the ion exchange resin industry.
A modified all-in-one DMSO-activating and base releasing reagent for the Parikh-Doering-type benzylic oxidation reaction
Authors: Xie Jiaqian , Male Louise , Jones Alan
Published: April 2024

The Parikh-Doering reaction, an example of the series of DMSO-mediated selective oxidation named reaction family, finds ongoing use in natural product synthesis when mild oxidative reaction conditions are required. The original conditions require the use of Py-SO3 and NEt3 along with DMSO and DCM. As part of our ongoing interest in sulfating agents, we recently disclosed the novel structure of tributylsulfoammonium betaine (TBSAB) that has a formal N-S bond (not dative) and may indicate that other N(sp3) amine-SO3 complexes have been misassigned. Herein, we explore a commercial sulfating agent, triethylamine-sulfur trioxide complex, as an all-in-one sulfation and base releasing reagent for a modified Parikh-Doering reaction. Single crystal X-ray crystallography further confirms our hypothesis than triethylamine-sulfur trioxide complex exists as triethylsulfoammonium betaine (TESAB). Employing TESAB as an all-in-one reagent, a range of primary and secondary alcohols were screened for competency. Reactivity was observed for the first time with 1) a non Py-SO3 sulfating agent and 2) without the need for additional base. Moderate to good yields of aldehydes and ketones can be prepared in an atom-efficient improvement with concomitant removal of toxic pyridine by-products.

Word and Image in Alison Bechdel's Memoirs
Authors: Moloney Ciara
Published: April 2024

Abstract: Alison Bechdel's graphic memoirs— Fun Home, Are You My Mother? and The Secret of Superhuman Strength —explore the relationship between word and image, both in their form, as comics, and narratively, via Bechdel's musings on self-expression, sexuality, psychoanalysis, and exercise. On each of these sites, she is deeply concerned with the pervasive dichotomies of subject/object, self/other, and past/present. The fraught dichotomy between words and images forms the organizing force for how she writes and draws about all dichotomies, as she disrupts the hierarchy between word and image of Lacan's symbolic order without, as many feminists scholars have, deeming the symbolic order of language inherently patriarchal. Drawing from Julia Kristeva's theorizing of Lacan's symbolic order, Hillary Chute's comics theory, as well as W.J.T. Mitchell's work on the relationship between word and image, I analyze each book sequentially. In her memoirs, Bechdel disrupts the very distinction between word and image. When she recreates book passages and letters, these are not simply transcriptions, but drawings of physical pages, treating words as images. Chute and DeKoven's definition of comics focuses on it as a dual medium, but in Bechdel's memoirs, the relationship between word and image is not as stable as duality. It is a collaboration requiring constant renegotiation.

Authors: Shegena GK , Ibrahim AA , Takele MK , Birri DJ
Published: April 2024

Background: Mother-to-child transmission (MTCT) of HIV is the primary source of HIV infection in children younger than 15 years. The knowledge of pregnant women about MTCT and its prevention is essential in the control of MTCT of HIV.
Objective: To assess the knowledge of Mother-to-Child Transmission of HIV (MTCT) and the prevention of MTCT (PMTCT) of HIV among pregnant women attending the antenatal clinic at the Wereda 04 Health Center, Kolfe Keranio sub-city, Addis Ababa, Ethiopia.
Methods: This study used a cross-sectional design. It used systematic random sampling to select 231 participants from the clinic attendees. Data were collected using a semi-structured questionnaire. Binary logistic regression was used to determine the association between variables.
Results: About 78.1% and 74.6% of the participants knew MTCT and PMTCT of HIV, respectively. Close to half (43.5%) agreed that MTCT of HIV could occur through breastfeeding, 33.5 % agreed it could be transmitted during pregnancy, and 23% agreed it could be transmitted during labour and delivery. Nearly 75% knew that MTCT of HIV is preventable, but only about half (47.9%) knew that MTCT is preventable through antiretroviral therapy (ART). The knowledge of pregnant women about MTCT and PMTCT was associated with place of residence as it was lower in rural women. 
Conclusions: Some of the participants were not knowledgeable about MTCT and PMTCT of HIV. Effective health education is recommended for women of reproductive age to reduce the MTCT of HIV.

Authors: Bhoir VV , Gujar DA
Published: April 2024

Periodontal plastic surgery is a more conservative and precise technique practised to create more functional and aesthetic results for the treatment of mucogingival problems. The presence of an aberrant frenum is one of the aetiological factors associated with the persistence of a midline diastema. Inadequate dental plaque removal, poor oral hygiene, bifid tongue, impaired speech, and mucogingival problems like recession and black triangles need more attention. Ankyloglossia, or tongue-tie, is a congenital anomaly with an abnormally short lingual frenulum. The aberrant frenum can be treated with surgical removal of the frenum using either frenectomy or frenotomy procedures. In the present case series, frenectomy was performed using a conventional scalpel technique for the treatment of tongue tie.

Published: April 2024

To improve their writing learning outcomes, it is necessary to carry out learning activities that involve student participation (student-centered). This can be achieved by using the Flipped Classroom technique as an appropriate teaching strategy. Because the flipped classroom is a relatively new method among Indonesian educators, it might be considered a new variation of imaginative learning. The current research, which is based on a descriptive case study, strives to provide a thorough and contextualized image of a specific phenomenon it is used to explain phenomena and circumstances that occur in real life. This was done through a google form using mobile phones and the internet to find out students'' perceptions of writing English. Practically speaking, the interviews were addressed to six participants (three men and three women). The outcomes of the semi-structured interviews reveal some similar patterns in general. Different participants had a degree of resemblance with their English class interviews. Second, while numerous other respondents claimed to be involved at the same level, the reasons for their statements differed. This perspective can help guide the design of questions so that students'' ideas about their participation in English e-learning are captured accurately. The aim of this study is to highlight the problems and solutions associated with teaching English writing to junior high school students. On the one hand, these difficulties include student talent On the other hand, the difficulties include students'' failure to generate ideas for writing in English, students'' lack of knowledge of English vocabulary, and students'' lack of motivation to learn to write in English

Referring to the importance of knowing the aspects of English learners in reading, this study identifies and analyzes the self-perceptions of English learners in reading. As the main data, scores on the self-perception scale in reading were collected from a self-perception survey using the Reader Self-Perception Scale (RSPS) questionnaire. The main data in the form of four aspects of self-perception, namely progress (P), observational comparison (OC), social feedback (SF), and physiological state (PS) were analyzed qualitatively to determine the level of each aspect/dimension of self-perception studied. This study found that the progress aspect was in a low category, while the other three aspects, namely observational comparison, social feedback, and physiological state were in the medium category. Based on these results, it is hoped that the level of reading self-perception of English language learners in higher education in this context can be improved, one of which is the presence of pedagogical and psychological support that can give a positive effect on self-efficacy assessments in reading.
