Rozwój metod leczenia uzależnienia od nikotyny postępuje powoli, gdyż osoby z zaburzeniami psychicznymi są zazwyczaj wykluczane z udziału w badaniach klinicznych. Istnieje szereg możliwości terapeutycznych wspomagania rzucenia palenia, obejmujących interwencje psychologiczne i farmakologiczne, które powinny być oferowane osobom z zaburzeniami psychicznymi palącymi papierosy. Pierwszym krokiem w pomaganiu osobom palącym wyroby tytoniowe i uzależnionym od nikotyny jest ocena intensywności palenia tytoniu i potwierdzenie uzależnienia od nikotyny. Aktualnie dysponujemy kilkoma formami metod leczenia uzależnienia od nikotyny – od edukacji, psychoterapii poprzez farmakoterapię i terapię zastępczą po uzyskanie stopniowych postępów z zastosowaniem metody redukcji szkód. W leczeniu farmakologicznym uzależnienia od nikotyny można wybrać nikotynową terapię zastępczą, wareniklinę lub bupropion. Zwiększenie skuteczności może być osiągnięte poprzez prowadzenie terapii antynikotynowej w ramach leczenia psychiatrycznego oraz promocji redukcji szkód jako akceptowalnego wyjściowego celu terapeutycznego. Strategia redukcji szkód jest podejściem do rozważenia indywidualnie, szczególnie w przypadku osób niezdolnych do zaprzestania palenia papierosów, pacjentów z ograniczonym wglądem chorobowym, pacjentów w zaostrzeniu choroby oraz uporczywie niewspółpracujących. W pracy przedstawiono zalecenia Polskiego Towarzystwa Psychiatrycznego odnośnie diagnostyki oraz różnych metod leczenia uzależnienia od nikotyny u pacjentów z zaburzeniami psychicznymi.
Dancing Polish Romanticism: Bronisława Niżyńska’s Chopin Concerto and the Balet Polski
Authors: Lian Jordan
Published: June 2023

This article analyses Bronisława Niżyńska’s leadership of the Balet Polski Reprezentacyjny’s (Polish Ballet Representative’s) inaugural 1937-1938 season as a study of the Second Polish Republic’s assertion of national identity. I analyse the ballet, Chopin Concerto, as a choreographic representation of Polish culture for the company’s international debut at the 1937 Exposition Internationale des Arts et Techniques dans la Vie Moderne in Paris, as well as how audiences in London and Paris perceived the choreographic representations of Poland. I preface the Balet Polski’s debut with analysis of the cultural geo-hierarchy that pervaded Europe’s post-imperial system in the interwar years. To do so, I foreground Europe’s cultural cartography with Larry Wolff’s conception of Europe as a continent divided between East and West, while also incorporating Pascale Casanova’s literary mapping of centre and periphery. Concurrently, I adopt choreographic analysis of Chopin Concerto to question canon and cultural hierarchies. The research framework delineates the difficulty Poland, as a new nation in the post-imperial system, faced in asserting its cultural presence.

Published: June 2023

Purpose: The purpose of this study was to examine the effect of pre-service Early Childhood teachers'flipped learning classes and the students' perception of the class, and to seek the direction of teachingand learning for the training of pre-service teachers. Methods: This study involved twenty-one students taking a play guidance class at E University. Theplay guidance class was operated as an intensive course for eleven weeks, and flipped learning wasutilized for seven weeks. First, a paired-sample t-test was conducted to verify the effectiveness of theflipped learning class. Next, text network analysis using the Netminer program and qualitative analysisof the contents of the reflection diary were conducted to examine the perception of the pre-serviceearly childhood teachers' classes. Results: First, the flipped learning classes of pre-service Early Childhood teachers were found to havepositive effects on self-directed learning, learning motivation, and cooperative self-efficacy. Second,because of text network analysis, play appeared as the most important word, followed by infant, class,learning, discussion, observation, teacher, and support as important words. As a result of qualitativelyanalyzing the reflection diary, it was confirmed that it was an opportunity for ‘reinforcing learning’,‘expanding experience’, and ‘experience of recalling the field’. Conclusion: It was confirmed that the flipped learning class is a learner-led class that reflects therecent changes in the educational field, and that it is a meaningful teaching and learning method totrain pre-service teachers in the field of Early Childhood Education.

Published: June 2023

Purpose: The purpose of this study was to classify college faculty members’ group types for the levelof teaching competency using latent profile analysis and to confirm the influencing factors of individualcharacteristics on latent profile group types. Methods: The data were collected from 482 faculty members at A University using an online survey,and 328 pieces of data were collected. After removing outliers through Z-score, 302 were used for latentprofile analysis. Results: The results of this study are as follows: (1) as a result of the latent profile analysis, four groupswere created according to the level of teaching competency, and we named the groups ‘adaptive’, ‘growth’,‘competent’, and ‘proficient’ referring to the expert development level, (2) individual characteristics (gender,major, career) had a statistically non-significant effect on teaching competency based on the latent profile,(3) faculty members who participated in sustaining teaching support programs were in a higher probabilityaffiliated proficient group rather than an adaptive group, and faculty members who applied programcontent in their classes showed a higher probability of belonging to the proficient group rather thanan adaptive, growth, or competent group. Conclusion: Based on these results, this study suggested a significant implication and the necessityof developing teaching support programs according to group types and constructing a system forcontinuous support. Also, this study suggested that colleges should encourage faculty members toapply the content of teaching support programs in their classes.

Authors: Jaf Pshtiwan T. , Ali Jafar A. , Razzaq Ayad A. A.
Published: June 2023

Corrosion is one of the disasters attacking the drilling tools, particularly the drill pipes. Drilling fluid is the corrosive that increase the rate of corrosion in the pipes. In this study, it is intended to reduce the corrosivity of drilling fluid using a Prosopis farcta powder material. A natural, biodegradable, and environmentally friendly additive is added to the fluid in different particle sizes and amounts to obtain the lowest corrosion rate. Experiments are conducted in a well-like environment (high pressure high temperature filter press) over a wide range of parameters including pressure, temperature, and properties of the drilling fluid under dynamic conditions. The aim is to eliminate or reduce the corrosivity of the mud as well as to control the losses. The results showed a lower corrosion rate, 0.0029 mm/year, using P. farcta material in comparison with those obtained by researchers in the previous studies.

Published: June 2023

Background

This study assessed in-hospital outcomes of patients with chronic systolic, diastolic, or mixed heart failure (HF) undergoing transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR).

Methods

The Nationwide Inpatient Sample database was used to identify patients with aortic stenosis and chronic HF who underwent TAVR or SAVR between 2012 and 2015. Propensity score matching and multivariate logistic regression were used to determine outcome risk.

Results

A cohort of 9,879 patients with systolic (27.2%), diastolic (52.2%), and mixed (20.6%) chronic HF were included. No statistically significant differences in hospital mortality were noted. Overall, patients with diastolic HF had the shortest hospital stays and lowest costs. Compared with patients with diastolic HF, the risk of acute myocardial infarction (TAVR odds ratio [OR], 1.95; 95% CI, 1.20–3.19; P = .008; SAVR OR, 1.38; 95% CI, 0.98–1.95; P = .067) and cardiogenic shock (TAVR OR, 2.15; 95% CI, 1.43–3.23; P < .001; SAVR OR, 1.89; 95% CI, 1.42–2.53; P ≤ .001) was higher in patients with systolic HF, whereas the risk of permanent pacemaker implantation (TAVR OR, 0.58; 95% CI, 0.45–0.76; P < .001; SAVR OR, 0.58; 95% CI, 0.40–0.84; P = .004) was lower following aortic valve procedures. In TAVR, the risk of acute deep vein thrombosis and kidney injury was higher, although not statistically significant, in patients with systolic HF than in those with diastolic HF.

Conclusion

These outcomes suggest that chronic HF types do not incur statistically significant hospital mortality risk in patients undergoing TAVR or SAVR.
Increased Plasma Non–High-Density Lipoprotein Levels and Poor Coronary Collateral Circulation in Patients With Stable Coronary Artery Disease
Authors: Sivri Fatih , Öztürk Ceyhan Banu
Published: June 2023

Background

This study investigated the relationship between coronary collateral circulation (CCC) and non–high-density lipoprotein cholesterol (non–HDL-C) in patients with stable coronary artery disease (CAD). Coronary collateral circulation plays a critical role in supporting blood flow, particularly in the ischemic myocardium. Previous studies show that non–HDL-C plays a more important role in the formation and progression of atherosclerosis than do standard lipid parameters.

Methods

A total of 226 patients with stable CAD and stenosis of more than 95% in at least 1 epicardial coronary artery were included in the study. Rentrop classification was used to assign patients into group 1 (n = 85; poor collateral) or 2 (n = 141; good collateral). To adjust for the observed imbalance in baseline covariates between study groups, propensity-score matching was used. Covariates were diabetes, Gensini score, and angiotensin-converting enzyme inhibitor use.

Results

In the propensity-matched population, the plasma non–HDL-C level (mean [SD], 177.86 [44.0] mg/dL vs 155.6 [46.21] mg/dL; P = .001) was statistically higher in the poor-collateral group. LDL-C (odds ratio [OR], 1.23; 95% CI, 1.11–1.30; P = .01), non–HDL-C (OR, 1.34; 95% CI, 1.20–1.51; P = .01), C-reactive protein (OR, 1.21; 95% CI, 1.11–1.32; P = .03), systemic immune-inflammation index (OR, 1.14; 95% CI, 1.05–1.21; P = .01), and C-reactive protein to albumin ratio (OR, 1.11; 95% CI, 1.06–1.17; P = .01) remained independent predictors of CCC in multivariate logistic regression analysis.

Conclusion

Non–HDL-C was an independent risk factor for developing poor CCC in stable CAD.
Is the Roman Catholic Church in the Philippines Turning Dark Green? Catholic Bishops Conference of the Philippines’ Environmentalism from Anti-Mining to Climate Crisis Response
Authors: Peracullo Jeane C.
Published: June 2023

The article examines whether the Catholic Bishop’s Conference of the Philippines (CBCP) has become “dark green.” It explores CBCP’s pastoral letters on environmental issues from 1988 to 2019. Using the framework outlined by Bron Taylor in Dark Green Religion: Nature, Spirituality, and the Planetary Future, I argue that there are shifts in the environmental consciousness of the Catholic Bishops, as evident in the pastoral letters. Since 1988, the Catholic Bishops Conference of the Philippines has exhibited a reliable commitment to environmentalism and its prophetic mission amidst various environmental challenges.
Meaning-Making Mechanisms on the Boundary between Religion and Sports

Published: June 2023

What characterises religious meaning-making on the boundary between church and sports? Drawing on Sanne F. Akkerman and Arthur Bakker’s theory about boundary crossing, this article analyses religious meaning-making in sermons from Christian services in the context of international sports events. The article demonstrates that potential learning mechanisms at this boundary are more effective when not only seeking harmonious coordination and legitimisation but also bringing out differences and confrontation.
My Body is Where I Exist: Poverty, Disability, and Embodied Resistance as a Theology of Practice
Authors: Radford Wren
Published: June 2023

This paper explores embodiment as a locus for theological practices of addressing socio-economic inequality, focusing particularly on the intersections of disability and poverty. Engaging the work of Sharon Betcher and Mayra Rivera, the paper explores the relationship between spirit and flesh, and highlights the need for theologies to engage with and learn from unruly, excluded bodies. The paper constructs three poetic accounts from a collaborative project with UK activists to highlight embodied practices of navigating and resisting inequality, and the creative, sensory knowledges necessary for developing critiques of oppressive systems.
60 años de historia natural en Colombia después de la Independencia: un análisis desde la transculturación científica
Authors: Piñeros Veloza Ivonne Patricia
Published: June 2023

En 1819 se proclamó la República de la Gran Colombia. Simón Bolívar fue el primer presidente y Francisco de Paula Santander su vicepresidente. El inicio de la República tuvo varios problemas de orden social, económico y político por resolver, los cuales no fueron impedimento para el desarrollo del conocimiento científico en el país. El objetivo de este artículo es analizar los hechos científicos que sucedieron entre 1820 y 1880, desde el concepto de Transculturación Científica. El artículo está dividido en tres apartados donde se abordan, cronológicamente, los avances de las disciplinas relacionadas con la historia natural. Se pudo concluir que en este periodo el desarrollo del conocimiento científico dejó grandes resultados y las bases para los futuros científicos nacionales.
El mito tecnológico. Una lectura a propósito de la crítica de Franz Hinkelammert al neoliberalismo
Authors: Moreno Gómez Jaime Alexander
Published: June 2023

Este artículo tiene como objetivo, plantear el concepto de la tecnología como mito, y por lo tanto como un espacio mítico, lugar de enunciación desde donde el ser humano establece la comprensión que tiene de la realidad que le corresponde vivir, y así, plantea su actuar sobre ella. Para ello se presenta brevemente y a manera de barrunto una introducción de un análisis de la coyuntura vivida con la pandemia del Covid-19, que servirá para contextualizar la urgencia de reflexionar sobre el tema central, y que además permitirá bosquejar la conclusión de este escrito. Luego se abordará el problema planteado desde la propuesta económico-teológica del pensador crítico Franz Hinkelammert, quien a lo largo de su obra ha presentado, de manera implícita, un análisis sobre el tema de la tecnología, y quien desarrolla radicalmente la concepción de la tecnología como un mito de la modernidad. Hacer este acercamiento nos obligará a recorrer las reflexiones que este mismo pensador tiene sobre la racionalidad económica perfecta, así mismo que sobre la concepción de la economía que emergió con la revolución industrial y que se radicaliza tras las subsiguientes revoluciones que se plantean en esa línea. A lo largo de este desarrollo argumental nos veremos en la obligación de pasar por otros conceptos clave de la propuesta de Hinkelammert, como el de ideología liberal y su concepción de concepto límite. El de mala infinitud que viene desde la lectura que nuestro autor hace de Hegel.  Y por supuesto el concepto de mito y espacio mítico, así como el de tecnología y su vínculo con el imaginario social de progreso que es impuesto dentro de la racionalidad económica y social del sistema-mundo imperante.
Teoría crítica de la tecnología en Latinoamérica: educando sobre el acceso a electricidad
Authors: Nelson Andrés Ravelo Franco
Published: June 2023

La convocatoria del XVIII Congreso Internacional de Filosofía Latinoamericana se equivocó al afirmar que los estudios sociales latinoamericanos sobre ciencia y tecnología no habían establecido una relación explícita con la filosofía. Como contraejemplo, este artículo analiza un curso de extensión fuertemente influenciado por los dos campos. Este estudio buscó identificar cómo el caso problematiza la educación en ciencia y tecnología en Latinoamérica y para esto se orientó por preguntas clave de la filosofía latinoamericana. Los resultados superan una discusión apenas didáctica para cuestionar si dicha educación debe/puede crear condiciones para que diferentes actores/actrices estudien su relación con el conocimiento, la tecnología y la propia educación, asumiendo su lugar histórico en la transformación de estas instituciones y de las desigualdades que reproducen.
Presupuestos metodológicos del posthumanismo para abordar el objeto tecnológico
Authors: Saab Alfredo
Published: June 2023

El presente artículo busca caracterizar los principios metodológicos más relevantes que usa el posthumanismo para abordar el objeto tecnológico. De esa manera, quiere contribuir al desarrollo de una metodología posthumanista dentro del llamado posthumanismo filosófico. Tales fundamentos se enuncian a partir de la construcción de ocho conceptos básicos: paradigmático, maquínico, arqueológico, geológico, material, vital, social y ontológico. La investigación sintetiza la propuesta de varios autores que desde el posthumanismo buscan la superación de la tradicional dicotomía sujeto-objeto, la constitución de una sociedad de máquinas, el derrumbamiento del antropocentrismo y la deconstrucción del concepto “humano”. El término “objeto” es cuestionado desde los diversos presupuestos metodológicos que intervienen para una representación desde el continuum naturaleza-cultura. Una posibilidad no antropocéntrica de la realidad.
Teleconflicto: la virtualidad como producto de realidad en el conflicto colombiano
Authors: Forero Medina Nelson Camilo
Published: June 2023

El presente artículo busca señalar la existencia de dos conflictos, al menos, que se presentan en Colombia. El primero es un conflicto directo mayoritariamente sufrido en zonas rurales. El segundo es un tele-conflicto. De su raíz griega es un conflicto que se vive desde lejos (tele). Este último, si bien es virtual, produce efectos reales en los sujetos con un alto poder de decisión, especialmente en zonas urbanas. Con ello se busca señalar el rol de los medios como condición de posibilidad para la existencia del conflicto, pero no sólo debido al uso (abuso) que se pueda dar de ellos para la continuación del conflicto, sino por la misma manera en que es medializado. Para ello se analiza como caso empírico la refrendación de los acuerdos de paz de La Habana entre el estado colombiano y la guerrilla de las FARC-EP. Para ello se hará un análisis fenomenológico de la manera en que los medios interactúan con el sujeto. Con ello se busca observar el rol constitutivo de los medios de la experiencia humana. Con este punto como pivote, se señala la existencia de los dos conflictos previamente nombrados.
Una comprensión (in)material de las técnicas. A propósito de fomentar vínculos entre las humanidades y los Estudios de la Ciencia y la Tecnología
Authors: Antolínez Uribe David
Published: June 2023

Los estudios de ciencia y tecnología (STS) han replanteado nuestra comprensión de la ciencia y sus implicaciones en el tejido social. Sin embargo, se ha evidenciado una marcada tendencia de explorar con mayor detalle las ciencias naturales y las grandes producciones tecnológicas, dejando de lado las ciencias sociales donde no abundan los artefactos técnicos. El objetivo de este artículo es hacer un recuento de la evolución de este campo disciplinar para mostrar el origen de sesgo y reflexionar sobre sus implicaciones filosóficas. Asimismo, se apelan a algunas tesis de la teoría actor-red (ANT) y la ontología orientada a los objetos (OOO) para proponer la noción de técnica (especialmente las técnicas intelectuales) como una unidad de análisis alternativa que le permita a los STS superar ciertas predilecciones materialistas y aproximarse de mejor forma a las humanidades.
Entre voces y silencios. Biopolítica de las resistencias en la cotidianidad del conflicto territorial en los Llanos Orientales de Colombia
Authors: Quintana-Arias Ronald Fernando
Published: June 2023

Con el objetivo de evidenciar la forma en que la diversidad sociodemográfica ha resignificado el proceso de desarrollo territorial y origina líneas de fuga que trascienden la hegemonía de los poderes económicos-políticos-ambientales en los Llanos-Orientales, se realiza una metodología experimental que combina análisis situacionales, la genealogía, y la reconstrucción histórica de fenómenos sociales a través de 87 entrevistas a líderes sociales entre el 2019-2021. Los resultados muestran un territorio de activa conexión cultural que favorecen la lucha contra hegemónica dentro de las metáforas de “el mito del Estado nación” y “la imposibilidad de generar alternativas”. El análisis expone la existencia de rebeliones de conducta a través de resistencias cotidianas creativas, políticas y culturales, que favorecen el poder de la confianza, la solidaridad, la cooperación, el afecto, así como los liderazgos colectivos. Se concluye que el poder central no tiene la capacidad de capturar estas resistencias ya que no tiene la potencia analítica para percibir la reconfiguración del espíritu humano ni las variaciones del tejido social.
Integrating Computational Thinking and Data Science: The Case of Modding Classification Games
Authors: Grizioti Marianthi , Kynigos Chronis
Published: June 2023

Even though working with data is as important as coding for understanding and dealing with complex problems across multiple fields, it has received very little attention in the context of Computational Thinking. This paper discusses an approach for bridging the gap between Computational Thinking with Data Science by employing and studying classification as a higher-order thinking process that connects the two. To achieve that, we designed and developed an online constructionist gaming tool called SorBET which integrates coding and database design enabling students to interpret, organize, and analyze data through game play and game design. The paper presents and discusses the results of a pilot study that aimed to investigate the data practices secondary students develop through playing and modifying SorBET games, and to determine the impact of game modding on student critical engagement with CT. According to the results, students developed and used certain data practices such as data interpretation and data model design to become better players or to design an interesting classification game. Moreover, game modding process motivated students to question the original games’ content, leading them to develop a critical stance towards the game data model and representations.

The substantiation of the technical and economic parameters of the air launch aerospace system, which consists of a reusable unmanned aerial vehicle and integrated launch vehicle, is given. A combination of a turbofan engine and a ramjet engine is used as the unmanned aerial vehicle propulsion system. The considered vehicle is capable of delivering a payload into low-Earth orbits without the use of a spaceport. We have developed the methodology of the technical and economic substantiation of the parameters of the air launch aerospace system. The results were obtained by searching for the minimum of the objective function, which established the relationship between the technical and economic parameters of the aerospace system. For the objective function solution, the design parameters of the integrated launch vehicle and unmanned aerial vehicle were determined, as well as the limitation of the total acceleration velocity of the aerospace system. The methods used allowed us to determine the velocity constraints provided by the operation of the turbofan engine, ramjet engine, and the three solid propellant motors of integrated launch vehicle stages, as well as maximum dynamic pressure and maximum permissible temperature on the unmanned aerial vehicle surface. We determined the scheme for estimating the cost of launching the spacecraft into Earth orbit by the air launch aerospace system. The result of the substantiation is the determination of the technical and economic parameters of the integrated launch vehicle, unmanned aerial vehicle, and the aerospace system as a whole. The influence of the maximum temperature on the surface of the unmanned aerial vehicle and the specific impulse of the ramjet engine on the parameters of the aerospace system was also evaluated. The substantiation is the first step towards the creation of the Ukrainian aerospace air launch system.

It was shown that clinostating conditions induce autophagy without increasing of programmed cell death (PCD) index in the epidermal cells of the root apex of A. thaliana seedlings. After the phase of activation of autophagy, its regulatory weakening occurs, which probably indicates adaptive changes to the conditions of clinostating. The induction of autophagy correlates with an increase in the expression levels of atg8 genes, some of which (atg8e and atg8i) may be involved in the implementation of autophagy under the simulated microgravity conditions. The transcriptional activity of cytoskeleton genes involved in the implementation of stress-induced autophagy, in particular α- and β-tubulin genes, was analyzed. Joint expression of α- and β-tubulin genes and atg8 under the simulated microgravity conditions was revealed. These results illustrate the role of the cytoskeleton in the development of microgravity-induced autophagy and make it possible to identify genes specific to this type of stress. The induction of autophagy and PСD was studied under the action of gamma irradiation as a concomitant factor of space flights, as well as under the combined action of acute irradiation and clinostating. Gamma irradiation in doses equivalent to those in the spacecraft cabin (1 - 6 Gy) induced dose-dependent changes in the topology and cytogenetic state of the root apical meristem, as well as slightly inhibited of the early plant development. In the meristem, heterogeneity increased, PCD indexes, mainly proliferative death and autophagy, increased. With the combined action of gamma irradiation (2 Gy) and clinostating, the density of autophagosomes in the epidermal cell root apices of 6-day-old seedlings increased (24 hours after irradiation), and after 4 days it decreased, compared to the non-irradiated control.

In the paper, we show that the spectrum of acoustic-gravity waves in an isothermal atmosphere includes four specific evanescent modes. These modes are the solutions of the system of hydrodynamic equations for small atmospheric disturbances under the assumption that one of the quantities (horizontal or vertical components of particle velocity, density fluctuations, or temperature) is equal to zero. Three of the four specific modes (the Lamb wave, the Brunt-Väisälä oscillation, and the f-mode) are well known, but they were previously obtained as independent solutions. The recent discovery by the authors of the evanescent γ-mode made it possible to show that all four specified modes form a certain family of special modes of the isothermal atmosphere. On the spectral diagram of the frequency and the wave vector, there are four dispersion curves of these special modes in which one of the perturbed quantities is equal to zero. These curves belong to the evanescent region of the acoustic-gravity wave spectrum. They intersect each other at five points. It is shown that the specific modes cannot interact at the intersection points. The polarization ratios between two perturbed quantities have a different sign on either side of a particular curve if one of the quantities on this curve is zero. These properties can be used as indicators of the specific modes in experimental studies of the evanescent spectrum of AGWs. By using polarization relations, the possibility of observing these modes in the Earth’s atmosphere and on the Sun is also analyzed.

Direct calibration of indenter tip geometry by optical surface topography measuring instruments
Authors: Maculotti Giacomo , Kholkhujaev Jasurkhuja , Genta Gianfranco , Galetto Maurizio
Published: June 2023

Instrumented indentation test (IIT) is a depth-sensing hardness test allowing nano- to macro-mechanical characterisation of surface mechanical properties. Indenter tip geometry calibration allows nano-scale characterisation, overcoming the limits of conventional hardness tests. Calibration is critical to ensure IIT traceability and applicability for quality verification in manufacturing processes. The accuracy and precision of IIT are mainly affected by the indenter tip geometry calibration. State-of-the-art indenter tip geometry calibration reports either direct calibration by AFM, which is highly expensive and unpractical for industry, or indirect calibration methods, which are less accurate, precise and robust. This work proposes a practical, direct calibration method for IIT indenter tip geometry by optical surface topography measuring instruments. The methodology is complemented by uncertainty evaluation. The proposed approach is applied to Berkovich and Vickers indenters and its advantages are proven in terms of accuracy and precision of mechanical characterisation on metallic and ceramic material.
