Authors: hasan shatha sadiq , THAR AHMED , SALIH SHAKIR ahmed
Published: January 2023

Polymer concrete is a fine aggregate bound with a polymer binder instead of cement as in conventional concrete. The main aim of this research is investigation some properties (compressive strength, direct tensile strength, dry density) of epoxy polymer mortar with recycled glass as partial replacements of normal sand. According to the findings of this study, waste glass was substituted for 5%, 10%, 15%, and 20% of the sand in polymer mortar, respectively. When using waste glass as an alternative to natural sand, a decrease in dry density is observed when compared to the reference mixture by 2.14%, 2.23%, 2.32% at 7 days, 14 days and 28 days, respectively. Addition of 5%, 10%, 15% and 20% of waste glass as a partial substitute for natural sand leads to improvement the mechanical properties (direct tensile and compressive strength) of eco friendly polymer mortar. The results showed that recycled glass with 20% replacement ratio has given best results when compared with reference mix and other ratios. Finally, a regression analysis is used to establish the link between tensile strength and compressive strength.

Published: January 2023

Reactive powder concrete is an important and widely utilized materials in modern-day construction. During the last decades, in most countries including Iraq, a large number of old buildings has been demolished so that a million tons of recycled and reuse of building rubble have been produced. This study investigates the possibility of using different demolished building in green reactive powder concrete. The green reactive powder concrete GRPC mixes were prepared with 25% replacement of norm al fine aggregate by recycled aggregate (crushed concrete or waste glass) and waste, glass as a replacement of cement with 10, 20, 30%. The test result showed that it is possible to produced GRPC containing two different waste materials with properties similar to those of normal reactive powder concrete. Strength, properties (flexura1 and compressive strength) of green reactive powder concrete (GRPC) decreases slightly when using waste materials from demolished building as fine aggregate while increases when uses waste, glass powder WCP as a replacement of cement.

Published: January 2023

In aging steel bridges, it is necessary to accurately evaluate Life Cycle Cost (LCC) by judging more suitable timing for repair and reinforcements in order to keep good condition in service for a long period of time. Therefore, it will be important to predict as accurately as possible the remaining strength reduction in future for drawing reasonable maintenance scenario in aging steel structures. Since local corrosion damage often appears depending on structural details in members, it will be thought that corrosion progress according to corrosion environment and periodic inspection results must be considered to remaining strength estimation. In this paper, the remaining bending analyses on corroded H-shape weathering steel which had been used for 20 years, were conducted for future prediction of remaining strength reduction by using local corrosion surface data generated numerically. These surface data were generated by applying a simple generation model based on past corrosion progress model. Moreover, this model can consider locational concentration of attack factors by adopting appropriate probability distribution referred the contour maps of remaining thickness for actual local corrosion surfaces. From the analytical results, both remaining strength and torsional buckling behavior of upper flange with artificial corroded surface were almost the same to experimental results. Also, it will be predicted that remaining strength after 30 years from now was decreased as about 38% than initial state.

Published: January 2023

In Japan, drawing reasonable maintenance scenarios are required because increase in aging bridges is becoming more serious problem. For implementing maintenance scenarios, it will be effective to predict the deterioration of remaining load bearing capacity of structural members or whole bridge considering with corrosion damages in steel bridges. In this study, numerical corrosion surfaces which assumed until 120 years after were generated intending for actual aging truss bridge (about 100 years old) with many local corrosion damages. Each local corrosion surfaces were generated by using a simple corrosion progress model depending on probability distribution. Then, finite element analyses of this truss bridge which has numerical local corrosion surfaces were carried out for clarifying remaining load bearing capacity. Ultimate load bearing capacity was estimated from the maximum live-load magnification (Î±max) based on load-rating method in whole bridge analyses. Also, the deterioration curve of remaining load bearing capacity on whole bridge can be obtained as the relationship between the ï¡max and elapsed years (t). From the analytical results, the maximum load bearing capacity of the initial state model was estimated to Î±max=2.98 if the L live load in JSHB was assumed. And remaining load bearing capacity of whole bridge assuming after 120 years was estimated to Î±max =2.35 from Î±max-t relation. It will mean that the load bearing capacity has been decreased 21.1% than initial state.

Authors: Kahagala Hewage Dayani , Camille Christophe , Mirza Olivia , Clarke Todd
Published: January 2023

The structural optimization of innovative materials requires reliable numerical modelling, which can predict the structural behavior of the respective adaptation under possible scenarios. This paper presents the numerical modelling of macro synthetic fiber reinforced concrete (MSFRC) in railway sleeper applications. MSFRC is well known to improve post-peak flexural strength and toughness owing to the crack-bridging mechanism of fibers. Even though the fibers act individually along the crack interface, MSFRC depicts tension hardening as a material. Therefore, this paper highlights the integration of fiber-concrete composite action as a homogenous material towards efficient modelling of MSFRC in terms of computational resources required. The concrete damage plasticity model (CDP) being widely used to simulate the plain concrete behavior, the adaptability of CDP in the numerical analysis of MSFRC was investigated using the experimental data. Since the railway sleeper is subjected to impacts caused by wheel-rail irregularities, the accountability of the CDP parameters under both static and low-velocity impacts was also evaluated. Correspondingly, the modified CDP parameters reasonably represented the static and impact capacity, crack and damage evolution, and structural stiffness of MSFRC sleepers.

Authors: Askarinejad Hossein , Park Jundong , Pourbehi Mohammad
Published: January 2023

Cylindrical steel liquid storage tanks are widely used for water supply and industrial chemicals. The seismic response of these tanks differs from buildings as it stores liquid with different hydrodynamic characteristics. Steel tanks can be exposed to severe damages during earthquakes such as elephant’s foot buckling, diamond shape buckling, roof damage and failure of anchor bolts. This research investigates the seismic behavior of flexible steel water storage tanks using an analytical method. A series of parametric analyses are conducted for a typical liquid storage tank with different geometry properties and soil conditions. The effects of storage tank height, wall thickness, and subsoil type are investigated and their effects on the seismic response of the tank are evaluated and discussed. The results indicate that the soil type (representing shear wave velocity and shear modulus of the soil) has a profound impact on the base shear, overturning moment and hoop stress in the flexible tanks.

E-learning is being considered one crucial method of education, and various models and methods are being used to test its implementation and accomplishments. Among many, the DeLone MacLean information success (IS) success model is the most widely used in the assessment of e-learning systems’ success evaluation. The aim of this research was to study the effectiveness of the platforms used in e-learning at the Mongolian University of Science and Technology. In this study, we used the D&M IS Success Model to examine whether e-learning can be a successful transmitter of knowledge. Our intention was to assess the success of e-learning by the D&M IS Success Model, define the impact of current e-learning practice on individuals, and identify the factors that affect the quality. The survey covered 685 undergraduate and graduate students of the Mongolian University of Science and Technology. Results demonstrated that high-quality systems and information upsurge the individual impact. In addition, increased and continuous usage of e-learning systems plays a mediating role between system quality and individual impact. To ensure the continuous use and effectiveness of e-learning systems, special attention should be paid to factors such as service quality, systems’ simplicity and flexibility, and customer satisfaction.

Rapidly developing computer information technology is bringing significant changes in all aspects of our daily lives. It is no secret to all of us that at present society cannot be imagined without Information Communication Technologies. In general, the development of each country can be judged by the introduction of modern information and communication technologies into the industry. The innovative activity of pedagogues is the main factor in the reform of the education system. One of the most important aspects of modern education is the achievement of the innovative character of the pedagogical activity. The more innovation there is in the pedagogical activity, the better understanding of the teacher's own experiment can be achieved. In it, the teacher participates widely in creating, applying and improving innovation as the subject and organizer of the innovation activity. They seek to analyze the content in science and the essence of changes in knowledge and traditions. This article highlights the importance of using the "mental method" in teaching the" scientific education " module in the development of innovative activities of students of higher educational institutions in an informed environment.

Approche contrastive anglais-français de la création lexicale science-fictionnelle
Authors: Ray Alice
Published: January 2023

Imaginary genres have always played with language and lexicon in order to build their worlds. The science fiction genre, in particular, creates a lexicon on the borderline between literary creation and scientific and technical terminology so the stories can be framed elsewhere or in the future. The translation of these invented words can be a real challenge for translators because of their very nature as hybrids, but also because of the science fictional megatext. The translation treatment from English into French of these neologisms, known as “fiction terms”, shows different strategies of lexical (re)creation. Following a terminological approach, this paper presents a contrastive analysis of lexical creation strategies and morpho- syntactic structures between the two languages on a list of science fictional terms from the audiovisual field and extracted from a corpus of science fiction novels.
Problèmes d’acceptabilité des occurrences relevées dans les corpus informatisés : exemple des prédicats nominaux désignant une propriété ou un trait de caractère

Published: January 2023

In this paper, we present the problems encountered during our research in the field of nominal predication in Polish, in particular concerning nouns referring to properties and character traits. In a previous work on predicates referring to various activities and behaviors, carried out with the use of electronic corpora (the National Corpus of Polish Language, as well as electronic sources available on the Internet), we obtained a dictionary of verb-noun collocations with high lexical coverage comparing to traditional dictionaries (not based on electronic corpus research). Using the same corpus data and methodology as before, we conducted a study of the class of predicative nouns referring to properties and character traits. However, the results obtained following the application of this method proved to be unsatisfactory. In this article, we consider the reasons for this in order to optimize research methods later in our work.

Authors: Guo Shiying , Yu Wei , Wilson David I. , Young Brent R.
Published: January 2023

Cream cheese, a popular condiment, is widely used in people’s daily diet and in dessert making. To ensure high-quality cream cheese production, the pH value is generally used as the indicator to determine the end point of cream cheese fermentation. The inoculation time and time-dependent concentrations of biomass, lactose, lactic acid are all crucial for pH prediction. However, the inoculation time could vary for industrial applications with multiple fermenters. Moreover, the inoculation time impact on fermentation has not been investigated. This paper aims to build a cream cheese fermentation model predicting pH. The model includes a semi-batch kinetic model and an artificial neural network (ANN) model. The outcome of the model will help the cream cheese industries understand the inoculation time impact on fermentation time and organise better fermenter scheduling.
Cancer made me a shallower person: A minoritarian story in comics
Authors: Tzouva Pinelopi
Published: January 2023

The most widely circulated breast cancer narratives today have the structure of a Bildungsroman. They market personal growth, overcoming, and self-improvement, and reflect a strikingly neoliberal stance, even towards a potentially fatal illness as breast cancer. This is not the case with Miriam Engelberg’s graphic novelCancer Made Me a Shallower Person: A Memoir in Comics(2006), which resists this dominant tendency. Engelberg’s book, does manifest some of the typical Bildungsroman traits (e. g. introspective hero, need for belonging). Mostly, however, it is torn between opposing tendencies: Engelberg oscillates between vulnerability and detachment, irony and expectation, the urge to withdraw from a frightening situation and the desire to speak up against all the injustice and bad practices she witnesses. Engelberg never gives in to “the pressure to become someone different – someone nobler and more courageous than (she) was” (Engelberg 2006: xiii), but mocks and denounces all oppressive cultural attitudes. Instead of becoming “deeper” and more spiritual, in the socially prescribed ways, she chooses “the path of shallowness” (xiii), and remains a witty and critical outsider. These attributes, together with the episodic fragmentation of Engelberg’s book, bring it closer to a picaresque, the protagonist of which, like her, occupies a marginal position, moves from situation to situation, and makes the reader aware of the social norms while she simultaneously challenges and destabilizes them (Moenandar 2017: 5). The goal of my article is to examine Engelberg’s memoir as a minoritarian, hybrid form of writing between Bildungsroman and picaresque, pointing to alternatives to the dominant stories of overcoming and neoliberal survivorship.
Three-dimensional simulation of capillary rheometry for an estimation of extensional viscosity
Authors: Tseng Huan-Chang
Published: January 2023

It is difficult to directly measure the steady extensional viscosity of thermoplastic composite materials, especially at high extension rates. The famous Cogswell method was derived analytically from the pressure drop of entrance flow in commercial capillary rheometers for estimating the extensional viscosity. However, using Cogswell´s extensional viscosity has always resulted in over-predictions of pressure drop. Recently, the GNF-X (eXtended Generalized Newtonian Fluid) model with a weighted shear/extensional viscosity was proposed to show the typical extension-induced vortex growth in entrance flow simulations. Under given various values of Trouton’s ratio for extensional viscosity, the GNF-X model is introduced to perform three-dimensional flow simulations of capillary rheometry over a range of apparent shear rates. The difference between the predicted pressure drops and the relevant experimental data is minimized such that the estimation of extensional viscosity is optimized herein.

Spanish as a heritage language in Europe: a demolinguistic perspective
Authors: Loureda Lamas Óscar , Moreno-Fernández Francisco , Álvarez Mella Héctor
Published: January 2023

This paper offers an estimation of the number of Spanish speakers in Europe in order to analyze the demographic dynamics according to their migratory backgrounds. This demolinguistic approach allows us to quantify this group of Spanish heritage speakers and outline their demographic and linguistic profiles. Through analyzing specific family, social, educational, and geographic settings, this paper identifies a heterogeneous group of 1.7 million Spanish heritage speakers. Moreover, we discuss the social dynamics involved in the intergenerational transmission of the Spanish language in different contexts: spaces in which Spanish is an official language and in which different geographic varieties coexist, and spaces beyond the national borders of predominantly Spanish-speaking countries. In the latter, the demolinguistic analysis suggests that barely a third have been linguistically socialized in environments favorable to the intergenerational transmission of the Spanish language.
λ/20 surface nanostructuring of ZnO by mask-less ultrafast laser processing
Authors: Bai Shi , Li Zhaoxu , Obata Kotaro , Kawabata Shota , Sugioka Koji
Published: January 2023

Fabrication of nanostructures with a feature size much smaller than the laser wavelength is challenging due to the optical diffraction limit. It’s well known that the irradiation of polarized ultrafast laser generates periodic nanostructures, so called laser-induced periodic surface structures (LIPSS). Owing to the modulated field, the surface is periodically ablated to form specific patterns, which can be used for some photonic applications including surface-enhanced Raman scattering (SERS). In this paper, we investigate the morphologies of LIPSS on ZnO substrates by mask-less ultrafast laser processing. By adjusting the laser processing parameters, including fluence, pulse number, polarization, and pulse duration, the homogenous nanostrip array and nanopillar array are created. Furthermore, by adjusting the laser fluence, a single nanogroove with a width of ∼20 nm and a single nanocavity with a diameter of ∼24 nm are created. The gold nanoparticles are then coated on the ZnO nanopillar array for SERS application. We found that the concentration of defects in ZnO substrate is increased by the laser irradiation, which is beneficial for SERS performances to achieve an enhancement factor of SERS as high as 2.28 × 107.
Mineral Clays for Cleaning Tidelines on Paper-Based Artworks
Authors: Desbrière Alimatou , Dupont Anne-Laurence , Bajon-Bouzid Thalia , Drieu la Rochelle Isabelle
Published: January 2023

Clay minerals possess several properties such as ion exchange capability, alkaline pH, adsorptive, swelling, and plastic behaviour, most of which are governed by their interactions with water. They have the capacity to interact with soluble molecules, which is particularly interesting for art conservation treatments. For all these reasons clays deserve to be considered for green and sustainable paper conservation interventions. In this work two phyllosilicates with different properties, namely montmorillonite and sepiolite, were investigated for the removal of tidelines on artificially aged paper samples. Water exchange, cleaning efficiency, and pH were evaluated comparing the clays to gellan gum, a benchmark cleaning hydrogel. A pouch made with regenerated cellulose was used to avoid direct contact of the minerals with the paper. The water sorption capacity of the clays combined with the specific permeability of the cellulosic membrane allowed for a homogeneous and easy to control cleaning. The formation of new tidelines, an inherent risk to any local conservation treatment of paper, was avoided. As an example, sepiolite was used for the local cleaning of a paper-based artwork’s multiple tidelines.

Influence of Striker Design on the Absorbed Energy of Low-Energy Reference Specimens Used for the Indirect Verification of Charpy Impact Testers
Authors: Schuurmans Johan
Published: January 2023

Attempts to optimize the design of instrumented strikers for accurate dynamic force measurement were successful for a Toni MFL 300J Charpy impact tester (C-type hammer). However, the instrumented strikers for a Tinius Olsen IT406 machine (U-type hammer) failed to meet the indirect verification requirements at the low-energy level specified in ASTM E23-18, Standard Test Method for Notched Bar Impact Testing of Metallic Materials. To investigate whether the design of the striker contributes to the absorbed energy of low-energy reference specimens, the Charpy impact test was simulated for different striker designs by using finite element analysis. This exercise confirmed a contribution to the absorbed energy, attributed to the elastic energy stored in the striker at the point of brittle fracture (striker energy). The striker energy is proportional to the striker compliance, which is much larger for strikers for U-type machines than for C-type machines. Consequently, the absorbed energy of low-energy reference materials tested on C-hammer machines will be lower than when tested on U-hammer machines. The possibility of correcting the absorbed energy by subtracting the striker energy was investigated. For this purpose, historical records of instrumented tests on low-energy reference materials performed on pendulum impact testers with different strikers were analyzed. Correcting the absorbed energy shifts the striker bias. With no correction, more than half of the indirect verifications at the low-energy level failed, whereas nearly all passed after correction. Although a bias remained for individual strikers, the averaged corrected bias of all strikers was close to zero, indicating that the proposed method of correcting the absorbed energy of low-energy reference materials for the striker energy can potentially cancel out the striker influence, thereby yielding a striker/machine-independent value for low-energy reference materials.

Published: January 2023

Individuals experiencing homelessness face disproportionate rates of chronic health and mental conditions, disparities, and other disadvantages that contribute to being unsheltered and that call out to social workers at the micro and macro levels—in collaboration with colleagues across professional and service sectors—to examine, mitigate, and eliminate. This mixed-methods study documented the social and health determinants that put people experiencing homelessness at risk for chronic conditions that may lead to increased cancer risk, using a survey created by the research team and administered to 74 (n=74) unhoused male and female adults over the age of 18. We hypothesized that lack of access to healthcare perpetuates chronic disease and may increase cancer risk. The findings suggest areas where social workers—in keeping with the profession’s values of service, dignity and worth of the person, and social justice— must advocate for health education, screenings, care, engage in policy work, and drive further research.

Authors:   Universidad de Chile, Andrade Carlos , Sepúlveda Paula ,   Universidad de Cádiz
Published: January 2023

Field education is a component of the training process that allows the knowledge learned in the classroom to be applied in territorial spaces, which has been particularly difficult in the context of the COVID-19 pandemic. This requires accompaniment and monitoring for the acquisition of the expected skills. For this reason, the present study seeks to observe the relationship between the student's assessment of the support provided both by the practice center in the territories and by the university in the context of the pandemic. A quantitative design with an explanatory scope is used using secondary data for the analysis. As a result, it is highlighted that training in social work is correlated with how the students evaluate the accompaniment provided by the insertion centers in the territories and how they evaluate the accompaniment of the university in the field education process, which leads to the conclusion about the relevance of strengthening the conditions for accompaniment in the territories and the need for that the accompaniment given by the university to reinforce the link with the students in the training process.

Cantilever plate mid-span patch method for dynamically testing the in-plane Poisson's ratio of oriented strand board
Authors: Zou Yuying , Wang Zheng , Zhang Yifan , Zhou Yuhao , Shen Zhaoyu
Published: January 2023

A cantilever plate span-to-span patch method was proposed and demonstrated for dynamic testing of OSB Poisson’s ratio with high testing accuracy, simplicity, ease of implementation, and effectiveness. It is based on the patch method with zero transverse stress equal to the cantilever plate. Its effectiveness was verified by the four-point bending method and the patch strain gauge method with zero transverse stress. The simulation and theoretical analysis showed that the relative errors of OSB longitudinal and transverse Poisson’s ratios dynamically tested by the span-in patch method and the patch method with zero transverse stress were within ±3.8%. The OSB longitudinal and transverse Poisson’s ratios dynamically tested by the span-in patch method were in good agreement with those tested by the four-point bending method. Thus, the method is applicable to the cantilever plates with l/b= 5 to 6, b/h = 4 to 10, and l/b = 4, b/h = 7 to 10 for cantilevered plates, etc.

Background. Preoperative planning and design of microsurgical perforator flaps are the main steps for successful operation. The aim of this study was to determine the concordance between thermographic images obtained with smartphone thermal imaging camera and hand-held Doppler in the anterolateral thigh flap (ALT) model. Methods. A concordance study of diagnostic tests was carried out in Hospital of Lithuanian University of Health Sciences Kaunas Clinics, Plastic and Reconstructive Surgery Department during 2020–2022. Patients’ who were scheduled to undergo reconstruction with ALT flap and healthy volunteers were included in the study. Dynamic thermal images were performed with smartphone thermal camera FLIR One PRO in the typical ALT flap territory. The number and distance of hotspots in the thermogram with respect to anterior superior iliac spine were recorded in the study protocol. Later, the examination was repeated with hand-held Doppler and the control of hotspot was performed. Sensitivity, specificity and concordance index calculations were performed. Statistical analysis was performed using IMB SPSS 23.0. Results. A total of 100 ALT flap territories were examined. 266 hotspots were detected with thermal imaging and 275 perforators with hand-held Doppler. In 96.6% of cases, hotspots detected by a thermal camera were confirmed by hand-held Doppler as perforators. The sensitivity and specificity of thermography for the detection of perforators with respect to the hand-held Doppler were 93.5% and 96.9% respectively. The measure of concordance kappa index was 0.095 (p = 0.001). Conclusion. Smartphone thermal imaging have a high concordance with hand-held Doppler in perforator mapping, thus could be considered a useful adjunct to conventional methods.

Knowledge and attitude of farmers are among factors that influence pesticide intoxication in farms. They are influenced by several variables, including education. Farmers’ knowledge and attitude on pesticide intoxication may change after they receive interventions, such as education about pesticides. This study aimed to determine the level of knowledge and attitude of farmers on pesticide intoxication before and after an education session on pesticides in Sei Selincah Sub-district, Kalidoni District. This was a quasi-experimental observational analysis with a two-group pretest posttest design with a control group. This study used primary data from farmers in Sei Selincah Sub-district, Kalidoni District. Sampling was performed using the purposive sampling method and seventy-six respondents who met the inclusion and exclusion criteria were recruited. Results of the statistical tests using the Wilcoxon test showed that there was no difference in the level of knowledge and attitude of farmers before and after education, both fort the intervention group and the control group (p>0.05). Thus, education does not influence the level of knowledge and attitude on pesticides and pesticide intoxication among farmers.

Published: January 2023

The article provides an overview of research and development of databases since their appearance in the 60s of the last century to the present time. The following stages are distinguished: the emer- gence formation and rapid development, the era of relational databases, extended relational data- bases, post-relational databases and big data. At the stage of formation, the systems IDS, IMS, Total and Adabas are described. At the stage of rapid development, issues of ANSI/X3/SPARC database architecture, CODASYL proposals, concepts and languages of conceptual modeling are highlighted. At the stage of the era of relation-al databases, the results of E. Codd’s scientific activities, the theory of dependencies and normal forms, query languages, experimental research and development, optimization and standardiza- tion, and transaction management are revealed. The extended relational databases phase is devot- ed to describing temporal, spatial, deductive, ac- tive, object, distributed and statistical databases, array databases, and database machines and data warehouses. At the next stage, the problems of post-relational databases are disclosed, namely, NOSQL-, NewSQL- and ontological databases. The sixth stage is devoted to the disclosure of the causes of occurrence, characteristic properties, classification, principles of work, methods and technologies of big data. Finally, the last section provides a brief overview of database research and development in the former Soviet Union.
Recovery and Construction of Churches in the Ardatov Diocese in 2011–2021
Authors: Mariskin Oleg I. , Kirillov Eduard P.
Published: January 2023

Introduction. Qualitatively new changes in relations between the state and the church in Russia and Mordovia began during the period of perestroika and socio-economic transformation of the 1990s. One of the manifestations of this process is the gradual return of buildings belonging to the Church in the past and the construction of new churches.

Results and Discussion. Over the decade, the Ardatov Diocese of the Mordovian Metropolitanate passed the eventful path of formation and development. Today it conducts active spiritual, social, charitable and educational activities, restores the lost and erects new churches and monasteries. At the beginning, in a significant part of the parishes, the service was carried out in churches that were not restored after many years of destruction, in equipped houses of worship, in adapted premises. The task of restoring, repairing the facades and interiors of old churches with the status of objects of cultural heritage of federal and regional significance was urgent. Many forces and resources for the implementation of this goal are applied by the clergy, clergy and parishioners of the Ardatov Diocese. In the diocese has been actively building new churches, and in small parishes – Orthodox chapels.

Conclusion. The diverse socially significant activities of the Ardatov Diocese and the Russian Orthodox Church as a whole testify not only to the revival of the traditions of Orthodox spirituality itself, but also to the positive role of the Church in the processes of harmonizing social relations, in strengthening political and economic stability in the country.
Psychedelic integration challenges: Participant experiences after a psilocybin truffle retreat in the Netherlands
Authors: Lutkajtis Anna , Evans Jules
Published: January 2023

This article reports on integration challenges that were experienced by nine individuals who attended a three-day legal psilocybin truffle retreat in the Netherlands. The study employed a qualitative phenomenological approach, using semi-structured interviews to gain an understanding of participants' (n = 30) psilocybin experiences and their after-effects. While the study did not actively seek to measure integration issues or unexpected side effects, nine out of thirty participants (30%) spontaneously reported a post-experience integration challenge. These challenges included: mood fluctuations, ‘post-ecstatic blues’, disconnection from community, re-experiencing symptoms, spiritual bypass and perceived lack of support. Integration challenges were transient; they occurred immediately after the psilocybin experience (once the main psychedelic effects had worn off) and in the days and weeks following the retreat, and resolved with time. Integration challenges were also correlated with positive after-effects including long-term remission of significant health conditions. The experiences related in this article align with existing literature that describes the ‘spiritual emergency’ phenomenon; that is, the potential challenges that can arise after ecstatic experiences and how these challenges may be integral to the transformative potential of such experiences. We discuss the implications for psychedelic integration and harm reduction practices and for future psychedelic research.
