Abstract. Guemou L, Fellah S, Mairif M, Chouhim KML, Moussaoui B, Bouzemarene IN, Boubekeur C. 2023. Floristic diversity of the steppe area of Tissemsilt, Northwest of Algeria. Biodiversitas 24: 2483-2491. This study uses a stigmatist phytoecological technique to survey and evaluate the plant diversity of the Tissemsilt steppe region. The floristic analysis allowed us to draw up a list of 105 taxa, including 86 genera distributed across 34 families with a dominance of Asteraceae (24.76%), Poaceae (9.5%), and Fabaceae (8.6%). The comparison of the different biological types showed the importance of Therophytes (51.42%) that adapt well to environmental conditions. On the biogeographical level, our study affirmed the affinity of the Algerian steppe vegetation with the Mediterranean flora. The methodology adopted for the biodiversity measurement through the flora analysis using several ecological indexes has disclosed an important diversity through the Shannon index (4.96). At the same time, the Evenness of Pielou indicated regularity in the distribution of species (0.73). However, the perturbation index (63.8%) revealed an environment opening. It confirmed the presence of the phenomenon of Therophytization in this region by the dominance of Therophytes annual species more or less needing trophic, water resources and opening areas.

Abstract. Oktavia F, Sudarsono, Dinarti D. 2021. Preliminary QTL detection for Corynespora Leaf Fall disease resistance in rubber plant. Nusantara Bioscience 13: 53-61. Corynespora Leaf Fall (CLF) disease caused by Corynespora cassiicola fungus is one of the most important diseases of rubber trees. Conventional breeding to obtain the resistant rubber clones was constrained by the long time required for selection processes. This study was aimed to identify resistant loci linked with CLF disease on the rubber tree. Analysis was conducted on 104 F1 of BPM 1 x RRIM 600. The resistance evaluation of the population had been done against two C. cassiicola isolates and the molecular analysis was generated by using 28 selected SSR markers. There was a phenotypic variation in F1 resistance to both isolates with leaf wilting intensities ranged from 5.2% to 33.4% on CC-06 isolate, and from 3.5% to 36.4% on CC-22 isolate. There was no QTL identified on the genetic linkage map, but a single marker analysis showed that some loci associated with CLF disease. The associated loci can be used as a preliminary information to develop molecular markers linked with resistance to CLF disease to assist the rubber breeding programs.

Abstract. Gunay M, Genc TT. 2023. Molecular identification of yeasts from Turkish traditional cheeses: Extracellular enzyme activities and physiological properties important for dairy industry. Nusantara Bioscience 15: 1-11. The determination of yeast microbiota in cheeses and the physiological properties of yeasts are very important for the dairy industry. In addition, the physiological features, proteolytic and lipolytic activities, and stress tolerance of yeasts have a significant role in the selection of starter yeast species for cheese ripening. This study aimed to determine industrially important yeasts isolated from cheese samples. Molecular techniques identified the isolated yeast strains. The yeast strains’ extracellular enzyme activities, fermentation capacities, and thermotolerance and osmotolerance properties were also evaluated. A total of 81 yeast strains were isolated and characterized from three types of cheese samples. PCR-RFLP determined the isolated yeast strains and sequence analysis of ITS1-5.8S-ITS2 and 26S rDNA regions. A maximum parsimony tree was constructed by MEGA X software to evaluate the phylogenetic relationship of identified yeast strains. Candida intermedia, Candida parapsilosis, Clavispora lusitaniae, Debaryomyces hansenii, Kluyveromyces marxianus, Pichia kudriavzevii, and Wickerhamomyces anomalus yeast species were identified on cheese samples. The distribution of identified yeast species on cheese samples was determined as 48.1% for W. anomalus, 17.3% for K. marxianus, 14.8% for C. parapsilosis, 8.6% for D. hansenii, 4.9% for Cl. lusitaniae, 3.7% for C. intermedia and 2.5% for P. kudriavzevii. The W. anomalus yeast species was common in three cheese types. All strains of W. anomalus and P. kudriavzevii yeast species, three C. parapsilosis, and two Cl. lusitaniae yeast strains have important physiological properties for industrial applications. These yeast strains have the potential to be used in combination as starter cultures to improve cheese maturation in the future. This comprehensive study identifies yeast species by ITS1-5.8S-ITS2 and 26S rDNA regions and determines industrially important yeast species using multiple criteria (extracellular enzyme activity, stress tolerance, and fermentation capacity).

Abstract. Rahayu SYS, Fadila A, Fahmi MR. 2023. Identification of metallothionein protein in Anodonta woodiana as a biomarker of mercury (Hg) contamination. Nusantara Bioscience 15: 90-94. Heavy metal contamination can affect the survival of aquatic biota and will accumulate in the bodiesorganisms. Moreover, contamination identification at the molecular level can be analyzed using biomarker analysis. Biomarkers are responses measured individually, ranging from enzymes and xenobiotic measurements to organ and overall conditions. Biomarker analysis can be done by checking the metallothionein protein, this expression can be induced by Reactive Oxygen Species (ROS). Metallothionein (MT) has a thiol group with nucleophilic properties. As a result, this group can make Metallothionein able to find metals and free radicals. Therefore, prevention that can be done to reduce contamination at a higher trophic level requires monitoring the molecular level by observing the metallothionein protein. For example, Anodonta woodiana (Rea, 1834) or kijing taiwan induced by HgCl2 aims to characterize their absorption ability in the environment through metallothionein protein. That was conducted by the SDS-PAGE (Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis) method. SDS-PAGE electrophoresis results showed that the size of the metallothionein protein was 7 kDa, 15 kDa, and >30 kDa. Size >30 kDa is a group of proteins related to stress control or Heat shock protein (Hsp). The presence of Hsp is due to the body increasing stress protein synthesis and metallothionein to reduce normal protein synthesis. Based on the results obtained, this study revealed that A. woodiana could absorb HgCl2, as evidenced by the metallothionein protein characterization results.
Nonlinear optimization considering target feature points for bitelecentric camera calibration: experimental study
Authors: Zhu Jiangping , Luo Xiaopeng , Xiao Wenfan , Zhou Pei
Published: June 2023

The telecentric camera has found extensive application in microscopy imaging due to its remarkable attributes of maintaining constant magnification and minimal distortion within its depth of field. In telecentric imaging technology, the accuracy of measurements frequently hinges upon the calibration precision of the telecentric camera. In real-world scenarios, the shallow depth of field characteristic of telecentric cameras often leads to out-of-focus targets during the capturing process, which in turn results in the inability to accurately extract pixel coordinates of feature points, making it difficult for optimization algorithms to converge to the optimal value. We propose a nonlinear optimization algorithm based on pixel coordinates of optimized feature points for bitelecentric cameras. Incorporating pixel coordinates into the optimization process yields the theoretically optimal solution based on bitelecentric camera model. The obtained pixel coordinates are used for second initial value estimation, followed by the optimization of all parameters. Compared to existing methods, the proposed approach significantly reduces reprojection errors under both blurry and clear target conditions. Experimental results demonstrate superior performance in processing blurry defocused images.

Published: June 2023

The economic consequences of wind turbines on property prices and land values are a widely discussed political and social issue. In this study, in addition to the previous research on the impact of wind turbines on property prices, the influence of wind turbines on standard land values was examined for the first time. The study thus provides new insights, particularly with regard to the debate on distance areas and financial compensation payments for residents.

The chosen investigated area is located in Northern Germany and comprises three coastal districts in the state Schleswig-Holstein with a total of 1382 land zones and a high density of wind turbines. Using ordinary least squares models, the significant influence of wind turbines on the standard land values could be shown within a radius of up to 9 km. Using an exemplary municipality for the study area, an average change in the standard land value of 7.33% per 1000 m distance could be determined. Overall, the standard land values of less densely populated areas were affected more than urban areas.
From public debates to institutional establishment: Exploring the mission of the National Museum of Contemporary Art in Greece
Authors: Pandi Tina , Markellou Marina , Solomon Esther , Valianatos Thomas
Published: June 2023

In December 1997, the National Museum of Contemporary Art (Ethniko Mouseio Synchronis Technis–EMST) was established by law in Athens under the auspices of the Hellenic Ministry of Culture, compensating for the long-term absence of a state museum of contemporary art in Greece. Following the restitution of democracy in 1974, the question ‘what kind of museum do we need for contemporary art in Greece?’ was raised by artists and other professionals (critics, curators, gallerists, researchers) and explored through a series of public debates and events. However, only in the 1990s was this demand supported by politicians, eventually leading to the establishment of the EMST in 1997. This article examines the public debates developed by art professionals from 1976 to 1997 regarding the mission of the museum as an open, experimental institution in relation to the broader cultural and sociopolitical context. It also analyses the legislation related to its establishment and questions whether the above priorities and expectations were reflected in the relevant legal provisions.
‘Let’s go now to the difficult part of the day’: Judges’ mediatized identities in MasterChef Greece
Authors: Sarakatsianou Dimitra , Stamou Anastasia G. , Kamarianou Eleni
Published: June 2023

Viewing the MasterChef Greece judges’ identities as mediatized, namely, as constructed via particular semiotic resources (linguistic, visual, spatial) mostly resulting from decisions made by the show’s production, we examine the communicative and social functions of the show as being a popular example of a reality TV programme. The judges hold a crucial role, as their assessment affects the subsequent development of the show. By adopting a micro-level discourse analytical approach, we focus on the analysis of two interactions, in which two different judge personas emerge, namely the ‘harsh’ and the ‘supportive’ judge. The analysis of these interactions indicates that the two personas serve the judges’ mediatized identities as both professional chefs (expertise) and TV presenters (suspense, viewers’ engagement). Yet, they are related to contrasting constructions of both the culinary (authority vs. mentoring, hegemonic vs. ‘soft’ masculinity) and the (reality) TV world (negative vs. positive emotionality). Both personas seem to relate to the broader Greek sociocultural context, such as the gendered ideologies and the politeness strategies prevailing in Greek society. However, while the ‘harsh’ judge persona reflects more overt and traditional forms of control and regulation, based on surveillance and suppression, the ‘supportive’ judge persona echoes the more covert technologies of governance of late modernity, based on self-reflexivity and emotionalism.

Assessment and strategy development for SARS-CoV-2 screening in wildlife: A review
Authors: Italiya Jignesh , Bhavsar Tanvi , Černý Jiří
Published: June 2023

Coronaviruses (members of the Coronaviridae family) are prominent in veterinary medicine, with several known infectious agents commonly reported. In contrast, human medicine has disregarded coronaviruses for an extended period. Within the past two decades, coronaviruses have caused three major outbreaks. One such outbreak was the coronavirus disease 2019 (COVID-19) caused by the coronavirus severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Over the 3-year COVID-19 outbreak, several instances of zooanthroponosis have been documented, which pose risks for virus modifications and possible re-emergence of the virus into the human population, causing a new epidemic and possible threats for vaccination or treatment failure. Therefore, widespread screening of animals is an essential technique for mitigating future risks and repercussions. However, mass detection of SARS-CoV-2 in wild animals might be challenging. In silico prediction modeling, experimental studies conducted on various animal species, and natural infection episodes recorded in various species might provide information on the potential threats to wildlife. They may be useful for diagnostic and mass screening purposes. In this review, the possible methods of wildlife screening, based on experimental data and environmental elements that might play a crucial role in its effective implementation, are reviewed.

Intranasal dexmedetomidine with morphine or tramadol: A comparative study of effects on alfaxalone requirements for anesthesia in cats
Authors: Hommuang Kewvaree , Koatsang Nattika , Srikullabutr Suttiporn , Sattasathuchana Panpicha , Thengchaisri Naris
Published: June 2023

Background and Aim: Intranasal (IN) sedatives provide a non-invasive route for premedication drug administration. This study compared the cardiorespiratory and sparing effects of IN dexmedetomidine combined with morphine (DM) or tramadol (DT) on alfaxalone requirements for anesthesia induction in cats.

Materials and Methods: Twenty-four cats were randomly assigned to three groups: Dexmedetomidine combined morphine (IN dexmedetomidine 20 µg/kg plus 0.2 mg/kg morphine), DT (IN dexmedetomidine 20 µg/kg plus 1 mg/kg tramadol), or control (no premedication). The intravenous dose of 1% alfaxalone for endotracheal intubation was recorded with sedation scores, cardiorespiratory parameters (heart rate and respiration rate), and side effects.

Results: Both DM and DT were associated with significantly higher sedation scores than baseline, and sedation scores were found to be highest 20 min after premedication. Sedation scores were comparable between DM and DT groups. Side effects, including hypersalivation, vomiting, and pupillary dilation, were observed in the DM and DT groups. The dosage of alfaxalone required in the DM group (1.5 ± 0.3 mg/kg) was comparable to that of the DT group (2.0 ± 0.6 mg/kg, p = 0.0861), and both groups required significantly less alfaxalone than the control group (3.0 ± 0.6 mg/kg; p < 0.01). Heart and respiratory rates were comparable between the DM and DT groups. Duration of anesthesia in the control group (11 ± 4 min) was significantly shorter than in the DM (29 ± 5 min, p = 0.0016) and DT (38 ± 14 min, p < 0.001) groups.

Conclusion: Intranasal administration of DM or DT produces good sedation and offers an alternative, non-invasive route for cats undergoing general anesthesia.

Evaluation of testosterone, estradiol and progesterone immunoassay calibrators by liquid chromatography mass spectrometry
Authors: Handelsman David J. , Jones Graham , Kouzios Dorothy , Desai Reena
Published: June 2023

Objectives

In clinical practice, steroid measurements are performed mainly by direct, non-extraction immunoassays adapted to high throughput, automated immunoassay platforms and employing secondary calibrators. The accuracy of such steroid immunoassays is limited by cross-reactivity with structurally related steroids and nonspecific matrix interference as well as the metrological traceability of manufacturer supplied calibrators. The accuracy of steroid immunoassay calibrators has been little investigated by independent chemical methods.

Methods

Steroid concentrations of 41 calibrators (4–6 replicates per calibrator) supplied by four manufacturers for use in testosterone (T), estradiol (E2), and progesterone (P4) commercial immunoassays were measured by ultra-pressure liquid chromatography-mass spectrometry (UPLC-MS).

Results

Among 14 non-zero T calibrators, six (43 %) deviated significantly from the label concentration with 29 % outside 20 % of it. Among 14 E2 calibrators, eight (57 %) deviated significantly, whereas seven (50 %) were outside 20 % of the label concentration. Among 11 P4 calibrators, eight (73 %) deviated significantly whereas four (36 %) were outside within 20 % of the label concentration.

Conclusions

We conclude that inaccurate calibration of manufacturer’s supplied standards may contribute to inaccuracy of commercial direct steroid immunoassays.
An improved Kloubuchar ionospheric correction model for single frequency GNSS receivers
Authors: Devanaboyina Venkata Ratnam
Published: June 2023

The enhancement of positional accuracy of single frequency ionospheric correction models is an urgent need for low-cost and smartphone GNSS users. The available single frequency ionospheric correction models such as Klobuchar, NeQuick-G, NTCM, and Klob-BDS are providing ionospheric corrections for multi GNSS systems such as GPS, Galileo, BDS, and NAVIC systems. Otherwise, Global Ionospheric Map (GIM) Total Electron Content (TEC) corrections are also available to the GNSS users. In this letter, an improved Klobuchar ionospheric model is implemented. The slant TEC of dual Frequency GPS TEC observations is considered a reference. The Klobuchar model slant TEC observations are improved by taking the grid-based residual TEC corrections with the Adjusted Spherical Harmonic Function model. The Single frequency users can improve the ionospheric delay estimation using Klobuchar model and grid-based TEC residual corrections. The improved ionospheric correction model is tested under the biggest geomagnetic storm conditions during 24th Solar cycle that occurred in March 2015 over India. The proposed hybrid slant ionospheric TEC algorithms are evaluated with individual single frequency ionospheric models (Klobuchar, and GPS TEC) under adverse space weather conditions.
Unveiling and validation of a disulfidptosis determined prognostic model for osteosarcoma: new insights from prognosis to immunotherapy and chemotherapy
Authors: Zou Jiahao , Chen Liang , Xu Hao
Published: June 2023

Objectives

Disulfidptosis, a novel form of cell death, has been reported to the be result of high levels of SLC7A11 protein after glucose starvation that led to cell death. In this study, we aimed to illustrate the association between disulfidptosis and osteosarcoma.

Methods

Patients were collected from TARGET-OS and GSE21257, with a sequence matrix and clinical features. A total of 77 disulfidptosis genes were collected from the literature. A disulfidptosis-related prognostic signature (DSPR) was constructed using univariate Cox analysis, LASSO regression, and risk score computation. Nomograms were established by integrating independent prognostic factors and DSPR signatures. The Student’ t-test or Mann-Whitney U test was used to compare between the two groups. The Log-rank test, univariate and multivariate Cox regression was performed for survival analysis.

Results

A total of three distinct subtypes (C1, C2, and C3) with varying overall survival prognoses were identified. Comparison between C1 and C3 subtypes revealed 56 differentially-expressed genes, with six genes linked to prognosis. Using LASSO regression, a DSPR signature was constructed, which served as an independent prognostic indicator [hazard ratio (HR)=4.370, 95 % confidence interval (CI): 1.837–10.388, p<0.001], and further validated in an external GSE21257 cohort (HR=4.000, 95 % CI: 1.517–10.183, p=0.004). Nomogram incorporating clinical factors and DSPR signatures showed high predictive accuracy, with AUC values of 0.952 at 1-year, 0.890 at 2-year, and 0.873 at 3-year follow-up. Personalized therapy prediction indicated that low-point patients benefited more from anti-PD-1 immunotherapy, while for high-point patients, chemotherapy was a better treatment option.

Conclusions

In this study, we identified disulfidptosis-associated genes and unraveled their roles in osteosarcoma prognosis, constructed a prognostic signature, and provided guidance for personalized treatment strategies.

The 237Np (t
1/2 = 2.1 × 106 y) nuclide is produced in nuclear facilities. Its investigation is relevant to earth sciences as concerns environmental pollution and material circulation. We expected that this nuclide should be able to be analyzed by mass spectrometry with a neptunium tracer as a spike, such as that of 236gNp (t
1/2 = 1.5 × 105 y). Our research group has collected fundamental data for cross-sections of the 232Th + 7Li reaction for use in spike production. In addition to the complete fusion reaction, incomplete fusion also occurs, especially in the reaction of 7Li, which splits into α and t, and only a part of the projectile fuses with the target nucleus. In this study, the excitation functions of Pa isotopes, as products of the incomplete fusion reaction, were measured. The reaction mechanism is discussed by comparing the experimental values with those calculated using the EMPIRE code. In addition, we investigated the effect of incomplete fusion reaction on the entire reaction.
Experiencia del proceso de obtención de marcas de pisadas en material óseo según el tipo de sedimento y la profundidad
Authors: Saqqa Carazo Miriam
Published: June 2023

Esta experiencia se enmarca dentro del ámbito del estudio tafonómico de los huesos. La importancia de estos estudios radica en su utilidad a la hora de conocer y distinguir los procesos sufridos por los materiales óseos hasta su hallazgo. Son una de las maneras de acercarse más y de forma más concreta a los ambientes humanos con los que se relacionaban. Dentro de estos procesos sufridos por el material óseo esta experiencia se centra en un proceso físico concreto que da lugar a las marcas de pisadas. Las marcas que aparecen en los restos óseos, y que se han relacionado con el proceso físico del pisoteo, han sido objeto de estudio desde los años 80. El estudio de estas marcas se ha visto relacionado con el interés de conocerlas mejor y de esta manera poder diferenciarlas de otras marcas, como son las marcas producidas por la descarnación, corte o por material lítico en general. P. Andrews y J. Cook en 1985 fueron los primeros en señalar la similitud que existía entre ambas marcas, aunque también expresaron que existían diferencias entre ambas. De esta manera durante los años 80 y 90 del siglo XX, varios estudios se han centrado en determinar si con únicamente un estudio microscópico, y no con la necesidad de utilizar tecnología como el Microscopio Electrónico de Barrido (MEB), es posible identificar y diferenciar cualquier otra marca de las marcas de pisadas. En torno a esta idea se enfocan los intereses de esta experiencia. Una experiencia que desde un punto de vista humilde pretendía reproducir, observar las circunstancias y aspectos que rodean al proceso de la obtención de marcas de pisadas (tramplingmarks) en restos óseos; restosenterrados bajo diferentes tipos de sedimentos; sumando diversas variables, que tenían como fin arrojar más luz sobre dicha experiencia. De igual manera se pretendía observar si con mecanismos microscópicos,menos complejos que el MEB, se podían obtener unos resultados que fueran útiles para este campo de estudio.

PREMISAS INICIALES DE LA EXPERIENCIALa experiencia tenía como objetivo la elaboración de punzones de hueso siguiendo las diferentes técnicas documentadas en este tipo de material arqueológico para, posteriormente, examinar las marcas dejadas en el instrumento con el fin de distinguirlas y atribuirlas a los diferentes procesos de elaboración.El punzón es un instrumento puntiagudo usado para hacer incisiones y perforaciones en diversas superficies. Puede ser utilizado para realizar perforaciones en cuero, decoración en cerámica, etc. Este instrumento puede realizarse en varios materiales como hueso, madera o en metal.Para la elaboración de los punzones se utilizaron metapodios de cordero, previamente descarnados mediante cocción. Debido a la corta edad de los individuos todos los huesos tienen la epífisis sin soldar a la diáfisis. Antes de comenzar la experiencia, los metapodios se dejaron al aire libre durante varios días para someterlos a un secado natural. Como instrumentos para la elaboración de los punzones se utilizaron lascas de sílex y arenisca. La observación de las marcas traceológicas se ha realizado con una lente binocular.

Published: June 2023

El uso intensivo de pieles por parte de las sociedades cazadoras-recolectoras en climas templados y fríos, ha sido ampliamente corroborado en base a la información etnográfica, etnohistórica y al registro arqueológico. En cuanto a este último, aún cuando las pieles sólo se hayan conservado en casos excepcionales, existe información indirecta de su uso a través del análisis funcional de base microscópica, que ha puesto en evidencia la existencia de instrumentos que fueron utilizados para el procesamiento de pieles. Sin embargo, es poca la información que tenemos sobre el modo de procesamiento de las pieles de mamíferos marinos. Las experimentaciones realizadas hasta el momento han sido relativamente limitadas y la información etnográfica y etnohistórica sobre este tipo de cuero/piel en particular es escasa y contradictoria. Por este motivo, decidimos abordar un estudio experimental específico procesando un cuero de lobo marino de dos pelos (Arctocephalus australis).Las hipótesis sobre los modos de procesamiento a ensayar surgieron por un lado, de las descripciones etnohistóricas sobre las técnicas utilizadas por los Alacalufes, y por otro de la evaluación de los resultados del análisis funcional de base microscópica en instrumentos de sitios arqueológicos. En base a ellas se diseñó un protocolo experimental para ensayar la efectividad de distintos tipos de instrumentos y las etapas de procesamiento, en función de los resultados y productos que se deseaba obtener. Como correlato del trabajo experimental, buscamos identificar y caracterizar los rastros de uso que quedan en los instrumentos después del trabajo. El objetivo de este trabajo es presentar los resultados obtenidos durante la experimentación y discutir acerca de las líneas de análisis para determinar tanto la presencia como el uso del cuero en los sitios arqueológicos fueguinos.
Politics of the Absolute: Hegel and Object Oriented Ontology (Excerpt)
Authors: William Johns Charles
Published: June 2023

Within the last fifteen years there has been somewhat of a mini-renaissance of the philosophical concept of the absolute found in Quentin Meillassoux’s 2008 work After Finitude1 but also found in the Speculative Realism movement in general2. In this paper I will start by briefly describing the various mutations of this absolute in contemporary philosophy. I will then suggest some political implications associated with these notions of the absolute and then move onto an analysis of the absolute ‘whole’ (Hegel et’al) and the absolute (non-relative) independence of the discrete unit or individual object in the work of Graham Harman.
Del saber y del amor del inconsciente
Authors: Kargodorian Silvia
Published: June 2023

Para Jacques Lacan (1901-1981) el inconsciente opera, como el lenguaje, mediante metáforas o metonimias. Esto quiere decir que un significante (la palabra que designa a una persona, un objeto, una relación, un síntoma, etc.) se sustituye por otro con el cual guarda algún tipo de relación (por ejemplo, de semejanza). Desde una perspectiva psicoanalítica, se abordan contribuciones y debates desde la filosofía, la clínica psicoanalítica, la legibilidad de un discurso como un vínculo social fundado en la intersubjetividad y por último el énfasis en la cuestión política punto central de reflexión de nuestra investigación.

Published: June 2023

After a brief reflection on the characteristics of the historiography of psychoanalysis in recent decades, this article aims to show certain dilemmas and/or debates that cross the psychoanalytic field both in the region and in the contemporary world. To this end, the focus will be placed on the campaign organized by Nina Krajnik in favor of the psychoanalytic clinic and against the theoretical psychoanalysis of Slavoj Žižek, Alenka Zupan?i? and Mladen Dolar. It is of particular interest to examine how Krajnik’s arguments are embedded in a broader project aiming both at an expansion of the World Association of Psychoanalysis (WAP) headed by Jacques- Alain Miller, and at obtaining a monopoly over psychoanalytic theory and its political effects. It will be shown that it is possible to find the first manifestations of this process in Latin America even before the WAP project. In this sense, based on the productions of Dolar, Zupancic and Žižek, some current contributions of the Slovenian school will be shown, which are taken up here in the light of the Latin American context, seeking to illuminate the theoretical, institutional, political, ideological and cultural implications of the domination and hegemony of the Millerian current in the psychoanalytic field. This logic of power, as will be seen, has not prevented the emergence and development of some radical and irreverent approaches which, nevertheless, seem to have failed: in some Latin American countries, such as Argentina, Millerian psychoanalysis managed to impose itself even more intensely than in France itself. This poses a challenge and a dilemma worthy of consideration and which must be taken up.
Sobre las funciones de la argumentación y sobre la argumentación en el espacio variacional de los sistemas lingüísticos.
Authors: Rodríguez Monsiváis Raúl Enrique
Published: June 2023

Este trabajo tiene el objetivo de mostrar que los argumentos como construcción lingüística participan de los rasgos variacionales de los sistemas lingüísticos. Esto conduce a mantener una visión más dinámica de los argumentos. Este variacionismo y dinamismo se muestra principalmente en los diversos objetivos que se pretenden alcanzar al producir argumentos, pero también en otros aspectos vinculados al grado de distancia o cercanía comunicativa entre interlocutores, al grado de formalidad de la situación comunicativa y a si ocurre en un contexto dialógico o monológico.
Preparation, characterization of chitin-based activated carbon for Orange II removal
Authors: Wang Yanan , Ji Qingsong , Li Haichao
Published: June 2023

Chitin-based activated carbon (CAC) was prepared by a two-step process of carbonization and potassium carbonate chemical activation. The CAC was characterized using scanning electron microscopy (SEM), N2 adsorption/ desorption, Fourier transform infrared (FT-IR) spectroscopy, and X-ray photoelectron spectroscopy (XPS). The adsorption performance of CAC for Orange II (O II) was evaluated in terms of contact time, adsorption temperature, initial concentration, adsorption kinetics, adsorption isotherms, and thermodynamics. The CAC had a surface area of 1320 m2 g-1 and a total pore volume of 1.10 cm3 g-1. The maximum monolayer adsorption capacity was 1010 mg g-1 at 318.2 K for O II, respectively. Equilibrium isotherms showed that the Langmuir model had a higher coefficient of determination than the Freundlich model. The thermodynamic results indicated that the adsorption process of O II onto CAC 800 was spontaneous and endothermic. Given the results of this work, CAC can be used as an efficient adsorbent for the removal of dyes from wastewater.

COVID-19 has become a virus spreading quickly across the world.The government of Indonesia also immediately adjusted theconditions to minimize the spread of the COVID-19 virus byimplementing the health protocols 5M namely, wearing a mask,washing hands, keeping distance, avoiding crowds, and reducingmobility. With the advancement of technology, games can be used aseducational media to support users learning processes and increasetheir knowledge. Therefore, we conducted a study using the learningsupport media, namely interactive games based on a personalcomputer platform with the Windows operating system to help theusers understand the prevention of the COVID-19 virus byimplementing health protocols. This study proposes using a structurefor the iterative cycle process called the ADDIE model framework andusing the Unity game engine for its game development tools. Tomeasure the feasibility of interactive games as educational media, weuse the System Usability Scale method. Based on the applicationtesting of 50 respondents, interactive games get a score of 90 on a scalethat is acceptable. The results also indicate that interactive games aseducational media will improve the users learning process andmotivation about implementing the health protocols.
Changes in wealth inequality in the modern European-American civilization
Authors: Čižo Edmunds , Mietule Iveta , Kokarevica Anita , Ostrovska Inta , Komarova Vera
Published: June 2023

This study is aimed to analyze changes in wealth inequality in the modern European-American civilization (EAC). The research object includes five parts of the EAC from West to East: USA, Western Europe, Latvia, Ukraine, Russia. Statistical deciles is a tool for measuring and comparing wealth inequality: the top 10% (including the top 1%), the middle 40% and the bottom 50% of the population. 1995 and 2021 are time points for diachronic analysis. The source of empirical information is the data of the World Inequality Database. The study results showed that in different parts of the modern EAC, wealth inequality has different level and trends of changes: from rapid concentrating to deconcentrating. The USA and Russia are vivid examples of rapidly increasing wealth inequality and very strong wealth concentration, although average per adult national wealth in the USA is 4-5 times higher than in Russia. The USA, Western Europe, and Russia differ from each other in the cultural dimensions of Hofstede. The novelty of this study is the use by the authors of economic analysis for a deeper and more comprehensive understanding of the modern EAC, based not only on system-forming religious and cultural differences, but also on economic ones.
Factors influencing Vietnam youth’s participation in the nighttime economy
Authors: Nguyen Thi Thu Thuy
Published: June 2023

This research examines the factors that influence the behavior of young Vietnamese participants in the nighttime economy (NTE). The established factors were based on the results of a questionnaire distributed among 405 young individuals living, learning, and working in Hanoi, Da Nang, and Ho Chi Minh City. The data obtained confirm the predictive power of the theory of planned behavior (TPB) model to describe the NTE participants’ behavior. The study showed that perceived benefits have a direct influence on NTE participation behavior and an indirect influence through attitudes and the intention to participate; risk perception has only a direct effect on NTE participation behavior. One of the most significant factors in shaping behavioral intentions is financial readiness for consumption, which emphasizes the pragmatism and rationalism of NTE participants in spending their own money. In addition to being pragmatic and rational, the NTE participants’ behavior is influenced by cultural opportunities and the development of nightlife facilities.
Properties of self-compacting concrete modified with m-sand and spent foundry slag
Authors: Udayasree B. , Kumar G. Shravan
Published: June 2023

Due to significant industrialization, many countries have adopted the practice of industrial symbiosis, which involves utilizing the waste produced by one industry as a resource for another industry. The utilization of spent foundry sand (SFS), which is derived from the metal casting industry, poses a significant risk to both the environment and living organisms as a result of the existence of inorganic and organic substances. Nevertheless, this waste material can serve as a valuable resource for the construction sector. The utilization of SFS is significantly restricted due to insufficient comprehension of its concrete performance, despite its extensive range of applications. It is imperative to comprehend the behavior of spent foundry sand in concrete, particularly in relation to achieving a structure that is both strength-efficient and durable. The current study explores the usability of M-sand and spent foundry sand in self-compacting concrete. Reference concrete was produced by replacing river sand with 100% M-sand. M-sand was substituted with spent foundry sand in ratios ranging from 0 to 30%. Compared to the reference mix, SCC's mechanical and durability properties with 20% SFS were better. In comparison to the reference mix, SCC containing 20% SFS had higher mechanical and durability characteristics at 3, 7, 28 days, and 28 days, respectively. With 20% SFS, replacement showed better mechanical properties at all curing ages and better durability performance at 28 days of the curing period.
Klasztor w Suchej Beskidzkiej. Prepozyci w latach 1658–1709
Authors: Łatak Kazimierz
Published: June 2023

The article is situated in the current studies on the history and monastic culture in Poland in modern times. Its content consists of synthetic biographies of the provosts of the Lateran Canons Regular prebend in Sucha Beskidzka, who ruled in the years 1658–1709. The provosts were witnesses but above all co-creators of the history of the monastery, which played a significant religious, social and cultural role in the region. Above all, however, it was an important part of the town’s infrastructure, a symbol in its landscape, a shrine to which the faithful from the whole area made pilgrimages during the indulgenced feast, and a place of learning and teaching. Therefore, the biographies of its superiors, despite their encyclopaedic character, will undoubtedly be useful to researchers interested in the problems of monasticism in Poland, but also, and perhaps above all, to those researching the past of the town, the parish and the complex of monastic buildings.
Profanacje sakralne w aglomeracji krakowskiej w świetle kroniki Stefana Ranatowicza
Authors: Pęgier Małgorzata
Published: June 2023

Although the problem of sacral profanation was present in the reality of Polish society and clergy in the seventeenth century, however, it was not a subject eagerly discussed by chroniclers and historiographers in general. Stefan Ranatowicz CRL (1617–1694), author of the chronicle of the monastery of Canons Regular of the Lateran Congregation in Krakow at the Corpus Christi Church in Kazimierz, he raised this issue many times in the pages of his book, but he did it not to cause a sensation or to attract the reader with an interesting subject, but only to show future generations what not to do. He claimed that the described deeds of the ancestors are to be a model for posterity, but also a warning to them, therefore, he did not shy away from reporting not very commendable behavior. It fit perfectly into the didactic intention of his historiography.
