Рассматривается случай, важный для методики моделирования движения судна с помощью композитной модели ледяного покрова (GP-ice), составленной из вмороженных в пресноводный лед полиэтиленовых гранул сферической формы. Вначале определяются геометрические параметры плавающей в воде гранулы и компоновка модели при создании ледового поля. Приведенная толщина определяется как масса полиэтиленовых шаров вместе с намерзшим льдом, отнесенная к величине рассматриваемой площади. Путем решения алгебраических уравнений получены зависимости приведенной толщины от величины намораживаемого между гранулами слоя льда и диаметра гранул. Приведен график этих зависимостей, используемый при реальных опытах с моделями судов ледового плавания в экспериментах в композитном льду при определении характеристик их ледовой ходкости.

A case is considered that is important for the method of modeling the movement of a vessel using a composite ice cover model (GP-ice) composed of spherical polyethylene granules frozen in freshwater ice. First, the geometric parameters of a pellet oating in water and the layout of the model are determined when creating an ice eld. The equivalent thickness is de ned as the mass of polyethylene spheres together with frozen ice, related to the size of the area under consideration. By solving algebraic equations, the dependences of the equivalent thickness on the size of the ice layer frozen between the granules and the diameter of the granules are obtained. A diagram of these dependencies is given, which is used in real experiments with models of ice navigation vessels in experiments in GP-ice to determine the characteristics of their ice propulsion.

Выполнен поиск скрытых закономерностей формирования временных рядов показателей качества речной воды. На примере конкретного водного объекта (реки Исеть) проанализирован амплитудный спектр эмпирических данных, позволивших выявить частоты, которым соответствуют гармоники с наиболее заметньм вкладом в процесс, кажущийся хаотическим. Установлено, что такие гармоники удовлетворительно согласуются с эмпирическими зависимостями, что дает водопользователям инструмент для прогноза периодичности появления повышенной концентрации загрязняющих веществ. Нельзя считать до конца изученной природу обнаруженного явления, возможно связанного с такими гидрофизическими факторами, как «длинная память» и самоорганизация систем, находящихся вдали от термодинамического равновесия, либо с сезонностью изменений качества воды, либо даже с влияющими техногенными процессами. В любом случае выяснение механизмов формирования элементов упорядочивания рассматриваемых временных рядов, кажущихся хаотичными. представляет научный и практический интерес при планировании водохозяйственных решений.

An attempt was made to find hidden patterns in the series of substances that form river water quality. Using water quality data from the Iset River as an example, some time series that seem chaotic at first glance were analysed. The analysis allowed to identify the frequencies and associated harmonics that contribute the most to the process. This in turn can help predict the periodicity of the occurrence of increased concentrations and adapt the water usage to the current conditions. The nature of the detected phenomenon is not fully understood; it may be related to hydrological factors such as "long memory" and self-organisation of systems, as well as to anthropogenic processes. In any case, it is of scientific and practical interest in planning water management decisions to clarify the ordering mechanisms of the seemingly chaotic time series in question. научный и практический интерес при планировании водохозяйственных решений.

В статье приведены результаты исследования системы автоматического управления (САУ) температурой процесса получения биогаза с линейным ПИД-регулятором и широтно-импульсным модулятором. Отмечается, что создание требуемых температурных условий и сохранение их на оптимальном уровне для процесса получения биогаза невозможно без обеспечения теплом в биореакторов-метантенков биогазовой установки (БГУ). При проектировании САУ рассмотрена схема подогрева субстрата на основе оснащения биореактора водяной рубашкой с горячей водой, являющаяся самым простым теплообменным устройство, не требующим дополнительных мер по подготовке пара под давлением и усложнения конструкции биореактора при размещении теплообменных устройств внутри или вне биореактора. В ходе исследований получено, что САУ работает аналогично многопозиционной системе с реализацией максимального воздействия в начале переходного процесса и реализацией умеренного импульсного воздействия регулятора после выхода в установившийся режим, поддерживая при этом заданное значение температуры с допустимыми колебаниями. Практическая значимость полученных результатов состоит в том, что построенную САУ можно применять во всех режимах теплового процесса сбраживания БГУ: мезофильном, психрофильном и термофильном.

The article presents the results of a study of an automatic control system (ACS) for the temperature of the biogas production process with a linear PID controller and a pulse width modulator. It is noted that the creation of the required temperature conditions and their preservation at an optimal level for the process of obtaining biogas is impossible without providing heat in the bioreactors-methane tanks of the biogas plant. When designing the ACS, the scheme of substrate heating based on equipping the bioreactor with a water jacket with hot water is considered, which is the simplest heat exchange device that does not require additional measures to prepare steam under pressure and complicate the design of the bioreactor when placing heat exchange devices inside or outside the bioreactor. In the course of research, it was found that the ACS works similarly to a multi-position system with the implementation of maximum exposure at the beginning of the transition process and the implementation of a moderate pulse effect of the regulator after entering the steady state, while maintaining a set temperature value with permissible uctuations. The practical signi cance of the results obtained is that the constructed ACS can be used in all modes of the thermal fermentation process of the biogas plant: mesophilic, psychrophilic and thermophilic.

What does it take to be a good in-house translator? Constructs of expertise in the workplace
Authors: Schlager Daniela , Risku Hanna
Published: July 2024

In this paper, we explore constructs of translation expertise and experts held by practitioners working in the translation sector. Practitioner perspectives are often overlooked in the translation studies debate around expertise yet they can yield valuable insights and enrich the academic discourse. In our analysis, we draw on data from a qualitative interview study that focuses on the selecting and hiring process for in-house translators. The interviews were conducted with employers and translation professionals in Austria and reveal their understandings of what it takes to be a good translator. Aside from a relevant educational background as well as language and translation skills, these practitioners place particular emphasis on soft skills and the willingness of applicants to learn and adapt to diverse teams, tasks, and work situations. The emerging picture of translation expertise in the workplace is highly dynamic and context-dependent, calling for a more nuanced understanding of expertise in translation studies which highlights its social constructedness and encompasses situative and performative factors.
What makes a video game localisation tester? Exploring the effect of individual factors on error detection
Authors: Calvo-Ferrer José Ramón , Muñoz Villena Antonio Jesús
Published: July 2024

Video game quality assurance (QA) is vital to ensuring a high-quality gaming experience across different languages and regions. Competent localisation testers are expected to have advanced language skills, exceptional attention to detail, and familiarity with the game they are testing. However, individual testing performance differs, prompting the question of what constitutes a proficient localisation tester. In this study, students (N = 43) from the degree in Translation and Interpreting from the University of Alicante and the Specialist degree in Translation for the Video Game Industry from the University of Vigo were asked to test a localised video game which contained deliberate errors introduced for the purpose of this study. Subsequently, they completed questionnaires regarding localisation-related attitudes, personality traits, and trait anxiety levels. The results of various bivariate correlation and multivariate linear regression analyses indicate that translation expertise, low emotional stability, and a preference for screen reading were significant predictors of higher error detection rates. Furthermore, other variables such as attitudes towards video games, punctiliousness, and reading speed correlated with error detection in video game localisation testing. These findings may contribute to the enhancement of tester selection and training processes, resulting in superior localisations and more satisfying player experiences across diverse languages and cultures.
An Experimental Study on Viewing Perception and Gratification of Danmu Subtitled Online Video Streaming
Authors: Lu Sijing , Chen Xijinyan
Published: July 2024

With the surge of participatory culture and dynamic of media convergence, danmu have experienced their continued proliferation on East Asian online streaming. Facilitated by pseudo-synchronicity and congruency technologies, existing research has focused on describing and conceptualising the final product of danmu rather than being grounded in the empirical process of receiving danmu. We know little of how audiences perceive danmu and to what extent danmu affect viewers’ gratifications. Adopting an online-based experiment, this study contributes to examining viewers’ engagement with and gratifications from different types of danmu. It attempts to understand what types of danmu matter to the audience’s viewing gratifications in terms of its content and multimodality, and what (dis)connections can be observed between the audience reception of danmu and conventional subtitles. The results show that extra cultural information danmu stand out as the most gratifying type, significantly satisfying viewers’ utilitarian and hedonic needs for information and entertainment seeking. Scrolling speed and size are the two most influential multimodal factors in viewers’ gratifications with danmu. However, the potential connections between conventional subtitles and danmu depend highly on a video's content or genre.
Unveiling the redox non-innocence of metallocorroles: Exploring K-edge X-ray absorption near-edge spectroscopy with a multiconfigurational wave function approach
Authors: Khurana Rishu , Liu Cong
Published: July 2024

X-ray Absorption Near-Edge Spectroscopy (XANES) is an advanced technique for probing the local electronic structure of catalysts and is particularly effective in identifying the non-innocent nature of ligands in transition metal complexes. Metallocorroles with non-innocent corrole rings exhibit unusual electronic structures that challenge traditional density functional theory (DFT) methods, necessitating more rigorous methods that provide a reliable description of electron correlation. Herein, we explored the K-edge XANES spectra of metallocorroles of Fe, Mn, and Co using TDDFT and wavefunction-based methods. This is the first investigation to employ multireference methods, specifically RASSCF, RASPT2, and MC-PDFT, to study the redox noninnocent nature of metallocorroles reflected in their XANES spectra. We quantified the percentage of the non-innocent character of the corrole and the oxidation states of the metal in these complexes. Additionally, we captured more than singly excited excitations responsible for the pre-edge peak in the K-edge XANES spectra using multireference methods, that are beyond the capabilities of DFT. Our findings demonstrate that these advanced computational techniques are crucial for accurately predicting the XANES spectra, thereby providing a more reliable understanding of the electronic properties of such complexes. Furthermore, this study provides a new strategy for investigating the ligand redox noninnocence via integrated experimental and computational XANES.

Authors: Castelló-Martínez Araceli , Miguélez-Juan Blanca
Published: July 2024

La igualdad de género es uno de los Objetivos de Desarrollo Sostenible (ODS) de la Agenda 2030. Sin embargo, en la industria publicitaria diversos estudios han demostrado la escasa presencia de mujeres trabajando en el ámbito de la creatividad, ocupando cargos directivos y formando parte de los jurados de los festivales. El objetivo del estudio es analizar la presencia de mujeres en el ámbito de los festivales publicitarios. La metodología se basa en un análisis cuantitativo de las ediciones de 2000 a 2023 de los Premios Nacionales de Creatividad del Club de Creativos y de Cannes Lions International Festival of Creativity. Se analizan en el periodo indicado la composición de los jurados de ambos festivales, los premios especiales a profesionales del sector (cdec de Honor y Lion of St. Mark, respectivamente), las fichas técnicas de los grandes premios (Gran Premio Nacional de Creatividad y Grand Prix conseguidos por España, respectivamente) y los equipos directivos de las entidades organizadoras. Los resultados demuestran la infrarrepresentación femenina en los festivales publicitarios, especialmente en la composición de los jurados, en los reconocimientos especiales y en las fichas técnicas de las campañas más destacadas, corroborando los hallazgos de investigaciones previas. Pese a las iniciativas emergentes que defienden la paridad en la profesión publicitaria, esta igualdad todavía no es real ni se materializa en los eventos que visibilizan la industria y reconocen su evolución: los festivales publicitarios.

Authors: Naik B. M.
Published: July 2024

This paper presents the brief need and importance of synergy between higher and technical education and industry. A win-win game between industry and institute is very essential in raising their respective performances to greater heights. If synergy is achieved, then higher and technical education in India can hope to become globally competitive. India can then become a hub of education to attract students from abroad, as desired by the government. Synergy will also enable Indian industry to be competitive by world standards and enable India to become a developed country with a high rank in the world. NEP-2020 recommends synergy between the university and industry. In the past, many conferences and seminars in India have taken place, but the progress has been rather slow. This paper makes suggestions to bring synergy into practice. This paper is based on observations made during personal visits to several universities in developed countries, like the USA, UK, Germany, and India.

aims: To assess whether diabetes treatment satisfaction differs by ethnicity among participants with insufficient glycaemic control of type 2 diabetes mellitus in a clinical trial involving additional oral diabetes medications. Patient satisfaction is used as an indicator of healthcare quality. However, data on patients’ diabetes treatment satisfaction in the context of insufficient glycaemic control is limited. methods: Individuals with type 2 diabetes and an HbA1c of 58–110mmol/mol (7.5–12.5%) were recruited across Aotearoa New Zealand to participate in an 8-month randomised crossover study of vildagliptin and pioglitazone as add-on therapy to metformin and/or sulfonylurea. Participants completed the Diabetes Treatment Satisfaction Questionnaire (DTSQ) at baseline pre-randomisation. Treatment satisfaction scores were compared between ethnic groups and other characteristics using the analysis of variance and linear regression. Perceived hyper- and hypoglycaemia were summarised separately. results: Between February 2019 and March 2020, 346 participants (41% women, 32% Pacific peoples, 23% Māori, 26% European) completed the DTSQ. Mean (SD) age was 57.5 (10.9) years, diabetes duration was 9 (6.3) years and HbA1c was 75 (12)mmol/mol (9.0[3.2]%). At study entry, 40% were receiving monotherapy for diabetes. Treatment satisfaction was rated highly, with a score of 29(6) (interquartile range 25–33). Pacific peoples and older people reported greater treatment satisfaction than other groups (p <0.001). conclusions: Diabetes treatment satisfaction was high, particularly among Pacific peoples, despite suboptimal glycaemic control and insufficient glucose-lowering therapy.

Deletion of cyclin dependent kinase inhibitor 2a gene as a marker of oropharyngeal carcinomas non-associated with human papillomavirus and its prognostic value
Authors: Shponka I.S. , Bondarenko O.O. , Kovtunenko O.V. , Rakhmanov V.V.
Published: July 2024

Patients with human papilloma virus associated oropharyngeal squamous cell carcinoma generally have better treatment outcomes and prognosis compared to those with non-papillomavirus-associated oropharyngeal squamous cell carcinoma. However, prognostic evaluation for non-papillomavirus-associated oropharyngeal squamous cell carcinoma remains a problem that could be solved through the molecular mechanisms of squamous cell carcinoma for the purpose of further development of target therapies. Detection of cyclin dependent kinase inhibitor 2a gene deletion in oropharyngeal squamous cell carcinomas can have clinical significance as it may serve as a prognostic marker and potentially guide treatment decisions. To investigate and analyze cyclin dependent kinase inhibitor 2a gene alterations in oropharyngeal squamous cell carcinoma comparing with clinical data (age of the patient, TNM stage), their histological features and occurrence of papillomavirus infection markers (p16 expression). Formalin-fixed and paraffin-embedded samples after transoral radical surgery of oropharyngeal tumors from 26 male patients with average age 57.35±10.33 years were studied. Histological, immunohistochemical analyses and fluorescent in-situ hybridization were performed to assess histological features, p16 expression, and cyclin dependent kinase inhibitor 2a gene gene abnor­malities respectively. Homozygous deletion of cyclin dependent kinase inhibitor 2a gene was statistically analyzed and compared with p16 expression, age, and occurrence of nodal metastases in investigated patients. Our study demonstrated that the patients with non-papillomavirus-oropharyngeal squamous cell carcinoma with cyclin dependent kinase inhibitor 2a gene homozygous deletion had the highest risk of the nodal metastases development. Our findings suggest that not only detection of the loss of p16 expression, but also the evaluation of homozygous cyclin dependent kinase inhibitor 2a gene deletion might be predictive of worse outcome specifically in oropharyngeal squamous cell carcinomas.

Published: July 2024

Objective of the research was to find out the effectiveness of the use of osteoplastic materials based on the multipotent mesenchymal stromal cells of the adipose tissue during surgical treatment for restoration of bone defects in dental patients. The clinical material included examination of 79 patients who underwent replacement of bone defects of the alveolar processes and/or an alveolar part of the appropriate jaw by means of different osteoplastic materials and their combinations or without their application (the control group). Acid phosphatase activity in the oral fluid of patients was determined by means of the unified “end point” method. Alkaline phosphatase activity in the oral fluid was determined using a set of reagents produced by the company “Filisit-Diagnostika” (Ukraine). Oral fluid mineralization index (MI) of patients was calculated according to the ratio of enzymatic activity of alkaline phosphatase (ALP) to acid phosphatase (AP) according to the formula: MI=ALP/AP. Histological material was taken at the stage of installation of a dental implant. It was established that the use of a composition based on multipotent mesenchymal stromal cells of adipose tissue, platelet-enriched blood plasma and bone tissue substitute containing hydroxyapatite contributes to the improvement of regenerative processes in the bone tissue of the jaws, which is confirmed by a 28.68% decrease in acid phosphatase activity, an increase by 25, 97% of alkaline phosphatase activity in the oral fluid of group B patients and, accordingly, a 77.08% increase in the ratio of alkaline to acid phosphatase. According to the results of histological studies and phase-contrast microscopy, after 6-8 months of observation, in patients of group B, the areas of jaw defects were filled with newly formed bone tissue, identical to native bone, and the resulting trepanobioptas had the structure of cancellous bone with osteoblastic elements forming a chain around osteoid tissue. Having analyzed the results of biochemical and histological studies it was established that application of an osteoplastic composition based on the multipotent mesenchymal stromal cells of the adipose tissue, bone tissue substitute with hydroxyapatite and platelet-rich plasma allows restoration of bone defects of the alveolar processes and an alveolar part of the appropriate jaw in shorter terms. The method is an optimal alternative to traditional osteoplastic materials to be used in modern dental practice and dental implantation.

Objective: This work focused on the influence of managerial entrenchment on investment decisions. The objective was to understand the main characteristics of this variable in order to develop an instrument that could measure it..
 
Theoretical Framework: The decision-making process in finance is influenced by several factors related to the decision maker, such as their psychological and cognitive biases, their risk tolerance, and even their intentions to entrench themselves in the management of a company. Behavioral finance began to address the complexity of the decision-making process, starting from the complexity of the individual themself, displacing the idea of the pragmatic decision of Homo economicus that traditional theory represented
 
Method: A questionnaire was developed and applied to a sample of 154 managers. Then, the instrument was subjected to an exploratory factor analysis and a reliability test.
 
Results and Discussion: The findings of this research pointed to three components for measuring managerial entrenchment. These components were called “Managers’ Decision Autonomy”, “Power Hierarchies” and “Freedom of action” in the use of the organization’s financial resources. As a result, the instrument was validated, which was found to be capable of measuring entrenchment with consistent reliability.
 
Research Implications: The practical and theoretical implications of this research are discussed, providing insights into how the results can be applied or measured management entrenchment practices in investment decision-making.
 
Originality/Value: Thus, this qualitative study contributes both to the finance literature by summarizing the main characteristics of managerial entrenchment and to behavioral finance studies by providing a validation instrument for one of its main subjects of study.

Terapi Antiretroviral (ARV) bertujuan untuk mengurangi risiko penularan HIV/AIDS, menghambat perburukan infeksi oportunistik, meningkatkan kualitas hidup Orang DenganHIV/AIDS (ODHA) dengan menurunkan jumlah viral load dan meningkatkan jumlah CD4. Kunci keberhasilan terapi ARV adalah mempertahankan retensi. Lost To Follow Up (LTFU) dan kegagalan pengobatan menjadi kendala bagi ODHA dalam mencapai keberhasilan pengobatan ARV. Penelitian ini bertujuan untuk mengetahui prediktor hambatan mendapatkan retensi pengobatan ARV. Penelitian ini menggunakan rancangan case control dengan jumlah sampel 100 responden. Analisis data dilakukan dengan menggunakan metode chi-square. Hasil analisis bivariat, prediktor buruknya retensi berdasarkan persepsi pasien terhadap hambatan menjalani terapi ARV adalah kendala biaya transportasi (p=0.002; COR=8.34), kendala jarak perjalanan ke RSDM (p=0.002; COR=5.06), hambatan kesibukan lainnya (p=<0.001; COR=6,64), memiliki Pengawas Menelan Obat (p=0.003; COR=6.64), mengungkapkan status ODHA kepada orang lain (p=0.004; COR= 12.25), dan stigma (p=<0.001; COR= 12,3). Berdasarkan hasil uji multivariat persepsi pasien terhadap hambatan dalam menjalankan terapi ARV yang paling berdampak pada buruknya retensi terapi adalah mengungkapkan status ODHA kepada orang lain (AOR=13.1; p=0.042).

A vueltas con la biografía: una aproximación historiográfica
Authors: Rhalizani Palacios Juan  
Published: July 2024

Resumen
La simbiosis entre la contigüidad biográfica e histórica es casi tan antigua como esta última. No debe extrañarnos pues que las reflexiones sobre cómo escribir biografías sean hoy en día prolíficas, pues han preocupado a multitud de historiadores durante los últimos doscientos años. En efecto, también escritores, literatos y eruditos más antiguos se preocuparon de proyectar en la biografía distintos aspectos de su labor profesional, si bien con el paso de los años fueron aclimatándose a las nuevas tendencias, a los gustos de los lectores y al mundo académico. Con el paso a una historiografía más analítica tras la Segunda Guerra Mundial parecía que la biografía, en especial la de tipo político, podía desparecer del panorama. Nada más lejos de la realidad si tenemos en cuenta cómo el giro lingüístico y cultural propició desde los años ochenta un nuevo interés por parte de los historiadores interesados en cultivar la historia narrativa y el fenómeno de la individualidad. Así, el objetivo del siguiente artículo es efectuar un breve recorrido por las formas en las que la biografía o los relatos de vida han sido concebidos por la historiografía europea. En la parte introductoria abarcaremos desde sus orígenes hasta finales del siglo XIX; en la segunda, la central, explicaremos los cambios experimentados en el XX y en la tercera nos centraremos concretamente en la historiografía española desde autores tales como Pío Baroja hasta Isabel Burdiel.
