Published: December 2022

Pelaksanaan konstruksi berkelanjutan berkaitan erat dengan adanya teknologi beton, sehingga perlu dikembangkannya penelitian inovasi beton yang memiliki mutu tinggi dan memiliki kemampuan mengalir yang baik dalam melewati tulangan namun tetap ramah terhadap lingkungan. Penelitian ini bertujuan untuk menentukan efek subtitusi metakaolin dan variasi agregat limbah pecahan keramik pada kualitas beton memadat mandiri mutu tinggi khususnya kuat lekat. Metode yang digunakan dalam penelitian ini adalah metode eksperimental. Metakaolin berperan sebagai bahan subtitusi semen sedangkan agregat limbah pecahan keramik berperan sebagai bahan subtitusi agregat kasar. Benda uji yang digunakan pada penelitian ini berupa kubus dengan panjang sisi 15 cm serta tulangan ulir diameter 10 mm. Uji kuat lekat dilaksanakan pada beton berumur 28 hari dengan cara menarik tulangan serta mencatat beban dan displacement yang terbaca pada Universal Testing Machine (UTM) dan sensor LVDT yang disambungkan pada alat digital load meter. Hasil penelitian ini menunjukkan bahwa penggunaan metakaolin dan subtitusi agregat kasar dengan agregat limbah pecahan keramik mampu meningkatkan mutu beton. Penggantian variasi agregat limbah pecahan keramik dengan kadar 0%; 20%; 30%; dan 40% menghasilkan nilai kuat lekat berturut-turut 5,14 MPa; 8,03 MPa; 7,56 MPa; dan 5,73 MPa. Kuat lekat beton semakin menurun seiring bertambahnya subtitusi agregat limbah pecahan keramik saat melebihi penggantian kadar agregat limbah pecahan keramik sebanyak 20%.

The eye-tonometers are the important medical devices with measuring function which are necessary for the screenings of the intraocular hypertension (a serious risk factor for the glaucoma). However, it is not an easy task to ensure their correct metrological traceability. There is needed not only a wide range of various equipment but also the relevant know-how. Hence, a training centre for this quantity was established at the Czech Metrology Institute (CMI) within the framework of a smart specialisation concept for the intraocular pressure (IOP) metrology. The paper briefly outlines its history, scope, methodologies and future development plans

Published: December 2022

Natural lighting in building environments is an important aspect for the occupants' mental and physical health. Furthermore, the proper exploitation of this resource can bring energy benefits related to the reduced use of artificial lighting. This work provides some estimates of the energy that can be saved by using a lighting system that recognises indoor illuminance. In particular, it is able to manage the switching on of lights according to the daylight detected in the room. The savings from this solution depend on the size and orientation of the window. The analysis is conducted on an office by means of simulations using the INLUX-DBR code. The locations have an influence on the luminance characteristics of the sky. The analysis is conducted with reference to one city in the south and one in the north of Italy (Cosenza and Milan). The energy saving is almost independent of latitude and therefore representative of the Italian territory. it is highly variable according to exposure, being the highest for southern exposure (97% with the window size equal to 36% of the floor area) and between 26% and 48% (as a function of window size) for northern exposure.

This work presents a corpus of measurement methodologies utilized during a multidisciplinary project, aiming at the protection and conservation of ancient steel joints (clamps and dowels) of the Acropolis monuments, undertaken by the Acropolis Restoration Service (YSMA). The Laboratory of Physical Chemistry of the National Technical University of Athens collaborated with YSMA in designing and evaluating laboratory scale and field experiments, aiming in testing conservation materials.
The first phase involved the application of seven coating systems on uncorroded metal coupons. The application characteristics, physicochemical properties (colour, gloss, hydrophobicity), and the protection performance against accelerated corrosion and polymer photo-oxidation were measured. Poligen CE12 and Paraloid B67 +2% nano-alumina were selected as the two most suitable materials for pilot applications on corroded steel joints and outdoor field exposure at the monument site.
The assessment of the two coatings reversibility and of the corroded surfaces chemical alteration was undertaken by Raman spectroscopy analyses and orthophotographic documentation. During the 1-year field exposure, the corrosion development was retarded, but some local events of active corrosion could not be prevented. The joint areas coated with Paraloid B67 enhanced with 2% nano-alumina enabled more uniform application on corroded surfaces and exhibited better corrosion protection. In case of Poligen CE12, the nature of corrosion products indicated local acceleration of corrosion reactions.

Measurement systems in industrial practice are becoming increasingly complex and the system-technical integration levels are increasing. Nevertheless, the functionalities can in principle always be traced back to proven basic functions and basic technologies, which should, however, be understood and developed. For this very reason, the teaching of elementary basics in engineering education is unavoidable. The present paper presents a concept to implement a contemporary training program within the practical engineering education on university level in the special subject area of optical coordinate measuring technology. The students learn to deal with the subject area in a fundamentally oriented way and to understand the system-technical integration in detail from the basic idea to the actual solution, which represents the common practice in the industrial environment. The training program is designed in such a way that the basics have to be worked out at the beginning, gaps in knowledge are closed by the aspect of group work and the targeted intervention of a supervisor. After the technology has been fully developed theoretically, the system is put into operation and applied with regard to a characterizing measurement. The measurement data are then evaluated using standardized procedures. A special part of the training program, which is to promote the own creativity and the comprehensible understanding, represents the evaluation of the modulation transfer function (MTF) of the system by a self-developed algorithmic program section in the script-oriented development environment MALTAB, whereby students can supportively fall back on predefined functions for the evaluation, whose implementation however still must be accomplished.

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 204763, “Minimization of Ultrahigh-Temperature Filtration Loss for Water-Based Drilling Fluid With β-Cyclodextrin Polymer Microspheres,” by Hanyi Zhong, China University of Petroleum and the University of Oklahoma, and Xin Gao, SPE, and Zhengsong Qiu, China University of Petroleum, et al. The paper has not been peer reviewed.

_

Because of the rapid degradation of conventional biopolymer or synthetic polymeric additives at high temperatures (HT) or ultra-HT, effective control of water-based drilling-fluid filtration in these environments remains a major challenge in drilling operations. In the complete paper, β-cyclodextrin polymer microspheres (β-CPMs), generally used for drug release and wastewater treatment, have been evaluated and found to be effective, environmentally friendly ultra-HT filtration reducers.

Experimental Methods

Sodium bentonite (16 g) and deionized water (400 mL) was homogenized by stirring at 10,000 rev/min for 30 minutes. After hydration for another 24 hours, the suspension, which would be the base mud, was ready for use. β-CPMs were mixed into the base mud and hot rolled under temperatures ranging from 120 to 240°C for 16 hours. After hot rolling, the low-temperature/low-pressure (LT/LP) filtration (ambient temperature/0.7 MPa) and high-temperature/high-pressure (HT/HP) filtration test was carried out according to recommended standards. For the HT/HP filtration test, the pressure difference was set to be 3.5 MPa, while the testing temperature was equal to the hot rolling temperature when the temperature was lower than 200°C, and kept at 200°C when the fluid was thermally aged to rise higher than 200°C.

A typical HT-resistant water-based drilling fluid was used as a control sample. Several generally used HT filtration loss agents were added and hot rolled at 220°C to compare their effectiveness in HT filtration control.
Integrated Data Analysis Illuminates Commingled Smart Water-Injection Well

Tsarenko, Valentin N. Tarsky, SPE, and Lisa Jane Robson, Sakhalin Energy Investment Company. The paper has not been peer reviewed.

The objective of the complete paper is to share an evaluation of the background, drilling outcomes, and production and reservoir-pressure effects during 2 years of monitoring the first commingled updip smart water injector drilled in the Piltun area of the Piltun-Astokhskoye offshore oil and gas field in Sakhalin. The authors highlight details of the well-maturation decisions and expectations based on output of dynamic modeling studies.

Setting

The Piltun area consists of six main reservoir units (XXI-S, XXI-3, XXII-1, XXII-2, XXIII, and XXIV-2) being developed over two fault blocks (Block 1 and Block 2). All reservoirs have aquifers and gas caps, although the volumes, reservoir properties, and productivity of these reservoirs varies considerably, with the XXI-S and XXIV-2 reservoirs having the best rock properties and the highest recovery factors.

Updip Water-Injection History

In the original field development plan (FDP) created in 2008 and the reservoir management plan created in 2006, the Piltun area was to be developed by rows of commingled vertical downdip and updip water injectors (UDWIs), displacing oil to mid-rim vertical oil producers. However, the original UDWI concept was challenged early in development when the following geological surprises were encountered during drilling of the initial development wells:

- The structure was significantly higher than expected at the crest of the field.

- Thin, high-permeability (superfacies) layers were encountered in the producers and updip pilot holes.

- The injectivity of the downdip injectors was much lower than expected and required an upgrade to the water-injection pumps.

The FDP was reassessed in 2011. The design of the UDWIs was changed to long horizontal wells located at the gas/oil contact in the XXI-S, XXII-1, and XXIV-2 reservoirs only.

The 2011 FDP assumed that early water breakthrough could be managed by smart-well technology in the oil producers. However, these producers experienced technical failures, and the plan to install smart completions in all mid-rim producers subsequently was aborted.

In a 2015 FDP update, the design of the UDWIs was changed to vertical commingled wells equipped with a smart completion type, targeting only those reservoirs where clear incremental recovery and economic benefit was observed.

Razak, SPE, Jodel Cornelio, SPE, and Atefeh Jahandideh, SPE, University of Southern California, et al. The paper has not been peer reviewed.

_

The physics of fluid flow and transport processes in hydraulically fractured unconventional reservoirs is not well understood. As a result, predicted production behavior using conventional simulation often does not agree with observed field performance data. The discrepancy is caused by potential errors in the simulation model and the physical processes that take place in complex fractured rocks subjected to hydraulic fracturing. In the complete paper, the authors discuss the development of a deep-learning model to investigate the errors in simulation-based performance prediction in unconventional reservoirs.

Introduction

One of the major challenges for petroleum engineers working with unconventional reservoirs is a lack of models that accurately represent a physical relationship between the formation, completion and fluid properties, and production responses.

Statistical predictive models typically are used to extract sets of input parameters that better represent the properties of the field. However, a major drawback with statistical models is their inability to extrapolate from the training data set.

The authors propose a deep-learning predictive model based on a combination of physics and data to account for the errors that may have come from undiscovered physics or imperfect description of unconventional reservoirs. The model leverages the power of deep learning to account for systematic prediction inaccuracies resulting from incomplete knowledge about the reservoir model and the underlying flow processes. Deep neural network models trained with observed production responses and other related data in the field are used to enhance the prediction performance of simulation models with limited knowledge of flow physics in complex, unconventional reservoirs.

The data the authors use for their model consist of the following:

- Formation, completion, and fluid properties for physics-based reservoir simulation (xsim)

- Corresponding simulated production responses (dsim)

- Formation, completion, and fluid properties collected from the field (xfield)

- Related observed production response data (dfield)

The authors define simulation errors (derr) as the difference between dsim and dfield. Each derr is paired with xerr that is the concatenation of the corresponding xsim and xfield. The predictive model integrates a 1D convolutional autoencoder (AE) that extracts temporal trends in the simulation errors as a set of latent variables. These components are used to train deep regression neural networks to represent the complex relationship between the simulation errors and these latent variables.

Self-propulsion of droplets in a controlled and long path at a high-speed is crucial for electrochemical water oxidation, sub-millisecond organic synthesis and programable lab-on-a-chip. To date, extensive efforts have been made to achieve droplet self-propulsion by asymmetric gradient, yet, existing structural, chemical, or thermal gradient cannot last forever. It is equivalent to stating that a long gradient path also cannot sustain the high gradient density to realize the rapid droplet transport. Here, we demonstrate a circularly on/dis-charged mechanism for droplets to achieve the infinite self-propulsion with ultrahigh velocity of meters per second on a superhydrophobic film with positive and negative alternate potential. Two motion styles of the droplets on superhydrophobic films with different potential are proposed. By permutation and combination of these motion styles, droplet can overcome the trade-off between transport velocity and distance. Moreover, the droplets or even filaments can self-propel along the complicated pathways – such as roller coaster (anti-gravity transport), liquid diode, liquid logic gate as well as any patterned trajectory. Being assembled into a microfluidic chip, our strategy would be applied in the field of cell culture, chemical reaction, and diagnostic kit.

Published: December 2022

Objective

To analyze the risk factors of postoperative intracranial infection in neurosurgery, so as to provide reference for prevention and treatment of postoperative intracranial infection in neurosurgery.

Methods

156 patients who underwent postoperative intracranial infection in neurosurgery of our hospital from January 2016 to April 2022 were analyzed retrospectively. Pair principle was adopted, and the same number of cases from uninfected cases were selected as the control group; the clinical data of the two groups were statistically analyzed by SPSS22.0 software.

Results

Univariate analysis showed that primary disease, emergency operation, duration of operation, type of incision, operation mode, duration of indwelling drainage tube after operation, use of microscope during operation, whether to enter ICU, cerebrospinal fluid leakage after operation and secondary operation were the risk factors of postoperative intracranial infection (P < 0.05); multivariate logistic regression analysis showed that operation duration ≥ 4h, incision type, cerebrospinal fluid leakage and second operation were independent factors of postoperative intracranial infection (P < 0.05).

Conclusion

There are many risk factors for postoperative intracranial infection in patients from neurosurgery. It is necessary to take targeted preventive measures, such as shortening the operation time, treating cerebrospinal fluid leakage in time, avoiding secondary operation as much as possible, and using antibiotics prophylactically during perioperative period. These measures can effectively reduce the probability of postoperative intracranial infection in neurosurgery patients.

Published: December 2022

Classic denoising algorithms have always suffered from the disadvantage of being slow, even for the famous BM3D.This paper presents a fastst and effective image denoising algorithm, which is based on the aggregation. It is a relatively faster method that first applies other known denoising algorithms (such as DCT for Discrete Cosine Transform, Wavelet Transform, Wiener Filter Denoising, etc.), selects different chunking specifications and different parameters to obtain several different denoised images, and then aggregate them to obtain the final denoised image.However, not arbitrarily generated noise reduction image aggregation can get good results, only the right combination can get good denoising results.One of the suitable combinations is proposed in the paper guided by the above ideaExperiments show that the algorithm has good noise reduction performance, and the algorithm has the fastest running time among all classical algorithms, and the running time is only equivalent to less than one-tenth of other algorithms.

Published: December 2022

Purpose: Oculocutaneous albinism (OCA) is a group of rare, genetic disorders caused by absent/reduced melanin biosynthesis. The aim of this study was to explore the neurovisual, cognitive, adaptive, and behavioral profile of children affected by OCA, also evaluating any possible effect of the visual acuity deficit on the clinical profile.
Methods: Eighteen children (9 males, mean age 84.5 months ±41.2; range 18-181 months) with a molecular confirmed diagnosis of OCA were enrolled in the study. We collected data on clinical history, neurodevelopmental profile, neurological and neurovisual examination, cognitive, adaptive and emotional/behavioral functioning.
Results: A global neurodevelopmental impairment was detected in half of the children, without evolving into an intellectual disability. All the sample showed signs and symptoms of visual impairment. Low adaptive functioning was observed in 3 cases (17%). A risk for internalizing behavioral problems was documented in 6 cases (33%), for externalizing problems in 2 (11%) and for both in 5 (28%). Twelve children (67%) showed one or more autism-like features. Correlation analyses revealed significant associations between the visual acuity level and Performance Intelligence Quotient (p=0.001), Processing Speed Index (p=0.021), Vineland total score (p=0.020), Vineland communication (p=0.020) and socialization (p=0.037) domains.
Conclusions: Children with OCA may present a global neurodevelopmental delay that seems to ameliorate with age, and emotional/behavioral difficulties, along with the well-known visual impairment. An early neuropsychiatric evaluation and habilitative training are recommended to improve vision-related performance, neurodevelopment, and any psychological difficulties.

Non-Ewald methods for evaluating the electrostatic interactions of charge systems: similarity and difference
Authors: Fukuda Ikuo , Nakamura Haruki
Published: December 2022

In molecular simulations, it is essential to properly calculate the electrostatic interactions of particles in the physical system of interest. Here we consider a method called the non-Ewald method, which does not rely on the standard Ewald method with periodic boundary conditions, but instead relies on the cutoff-based techniques. We focus on the physicochemical and mathematical conceptual aspects of the method in order to gain a deeper understanding of the simulation methodology. In particular, we take into account the reaction field (RF) method, the isotropic periodic sum (IPS) method, and the zero-multipole summation method (ZMM). These cutoff-based methods are based on different physical ideas and are completely distinguishable in their underlying concepts. The RF and IPS methods are "additive" methods that incorporate information outside the cutoff region, via dielectric medium and isotropic boundary condition, respectively. In contrast, the ZMM is a "subtraction" method that tries to remove the artificial effects, generated near the boundary, from the cutoff sphere. Nonetheless, we find physical and/or mathematical similarities between these methods. In particular, the modified RF method can be derived by the principle of neutralization utilized in the ZMM, and we also found a direct relationship between IPS and ZMM.
New data on the hessite of the Baley ore field in Eastern Transbaikalia (Russia)
Authors:   Institute of Natural Resources, Ecology and Cryology SB RAS, Chita, Yurgenson G.
Published: December 2022

The relevance lies in the need to have information about the prevalence and paragenesis of hessite, which is one of the main mineral carriers of Te in the gold and silver ores of the unique Baley ore field in Transbaikalia. Te refers to the rarest chemical elements, the use of which has been steadily increasing lately. During the development of the Baleysky and Taseyevsky gold and silver deposits in 1929–1993, only Au and Ag were extracted from the ores, all Te went into the dump. Both deposits are not fully developed. The resources of the Au category P1 of the Baleyskoye field are estimated at 35 tons. The remaining Au reserves of the Taseyevskoye field, approved by the GKZ, amount to 105 tons. In the coming years, it is planned to extract the remaining reserves of Au-Ag ores from these deposits, containing Te mainly in the form of hessite, so knowledge about it will be important for the development of technology for its associated extraction. The purpose of the research is to study the mineral associations of the Baley ore field containing hessite. The object of research is Au–Ag ores of the Baley ore field, the subject of research is the forms of isolation and variations of the chemical composition of hessite. Method and methodology – optical and electron microscopy with the identification of shapes and sizes of individuals and aggregates of hessite, as well as the determination of its chemical composition. Research results: for the first time, the study of the ores of the Baley ore field with a high Te content was carried out and the relatively wide development of hessite was established. It is in association with petzite, altaite, silvanite, empresite, stutzite, pilsenite, as well as tellurium-containing uytenbogaardite, gold, many sulfosols and sulfides, quartz, dolomite, siderite, kaolinite, adular and other minerals. The peculiarity of the hessite Baley ore field is the variability of its composition. Two groups of hessite individuals have been identified. The first one includes hessite, which does not contain impurities. Of these, stoichiometric composition has only 22 %. They correspond to the composition of Ag2Te, in 32.2 % of cases there is an excess of Ag compared to Te (up to Ag2,1Te0,9), and in 45,8 % of samples there is a lack of Ag (up to Ag1,86 Te1,14). In part of the hessite individuals, it is compensated by the Au replacing it. For the first time, hessite containing an admixture of Pb, probably replacing Ag, was identified

Published: December 2022

Personality traits are qualities that make a person distinctive and describe stable behavior patterns. Therefore, understanding the influence of personality traits on behavioral intention will help predict investors’ investment decisions. This study aims to assess the impact of personality traits, i.e., openness to experience, neuroticism, conscientiousness, agreeableness, and extraversion, on investors’ behavioral intentions. Moreover, it assesses the mediating effect of attitude, subjective norms, and perceived behavioral control between investors’ personality traits and behavioral intention. The study employed a structured questionnaire on a sample of 413 retail investors. Further, obtained data were empirically examined on Smart-PLS 3.3 using the PLS-SEM method. The study found that perceived behavioral control, subjective norms, and attitude positively affected behavioral intention. However, the personality traits did not influence the intention directly. Further, mediation analysis revealed that attitude and subjective norm fully mediated the relationship between extraversion, neuroticism, openness, and intention. In contrast, attitude and subjective norms did not exhibit a mediating relationship between agreeableness, conscientiousness, and intention. Finally, perceived behavioral control fully mediated the relationship between personality traits and intention, except for conscientiousness. The study contributes by extending the applicability of the theory of planned behavior by examining the impact of big-five personality traits on behavioral intention and mediating the role of the theory of planned behavior’s dimension between personality traits and intention.
Propuesta de mejora en el diseño de interfaz y experiencia de usuario (UX) en Moodle: valoración del alumnado
Authors: Segovia-García Nuria
Published: December 2022

Las dificultades experimentadas por los estudiantes en el uso de los Learning Management System (LMS) pueden generar, entre otros, problemas de adaptación a la metodología virtual. El trabajo presentado parte del análisis de las principales dificultades experimentadas por el alumnado de una universidad virtual para posteriormente implementar una interfaz renovada y analizar si este rediseño ha contribuido a mejorar su experiencia de usuario (UX). Se ha empleado un cuestionario que, además de otros aspectos, integra la escala User Experience Questionnaire (UEQ). Las mejoras implementadas a través de una navegación simplificada y centrada en los elementos de uso habitual, junto con diferentes opciones de visualización del entorno y un diseño responsivo y adaptativo han generado una percepción positiva por parte del alumnado mejorando su experiencia de usuario. Se concluye la necesidad de establecer un diseño centrado en el alumnado que fomente el desarrollo experiencias de aprendizaje satisfactorias y acordes con las necesidades de estos. Facilitar una navegación sencilla (transparencia) donde el alumnado tenga el control de dónde se encuentra en todo momento (controlabilidad), y que lo pueda hacer desde cualquier lugar y dispositivo (efectividad) son aspectos que deberían estar siempre presentes en el diseño de estos entornos de aprendizaje.
Espíritu hacker: empoderando ciudadanos digitales
Authors: Pretto Nelson De Luca , Brandão Lapa Andrea , Bartolomé Pina Antonio
Published: December 2022

Abordamos la educación a partir de la perspectiva de los primeros hackers, aquellos apasionados por la programación compartida y el código abierto, pero también de todos los que entienden el conocimiento humano como un bien común. Desde el código de ética hacker, destacamos algunos de sus principios, como libertad, pasión, apertura, valor social, cuidado, acción y creatividad, para reflexionarlos desde la educación. Lo contemporáneo tensiona la democracia y la educación para la ciudadanía. Tal contexto requiere un cambio de paradigma que, defendemos, que puede venir inspirado por el espíritu hacker, con profesores e investigadores como intelectuales públicos. Se comprometen con su entorno social y cultural, y asumen el rol político del educador como activista en la formación de ciudadanos implicados con la transformación social en prácticas colectivas y colaborativas con y a través de las redes digitales. Los artículos incluidos en este núemro especial ofrecen una mirada más cercana a todo ese ecosistema tecnológico y educativo para ampliar el debate teórico y proponer un cambio de mirada para las políticas públicas.
The Frame of Love Affair and Its Representation in the Lexico-Semantic System of the Russian Language
Authors: Bushueva L. A.
Published: December 2022

The article analyses the means of linguistic explication of the frame love affair in the Russian language. The data came from Russian etymological, explanatory, and derivational dictionaries. The concept was described through the paradigmatic, syntagmatic, and derivational peculiarities of the words that represent the concept. The concept was reconstructed as a frame with the following slots: aim, action, agent, counter-agent, patient, evaluation, and result. The aim of the research was to show how the words that name the act of love affair represent this cognitive frame model. The act of love affair proved to reject previous beliefs and feelings while replacing the former with the other. The agent violates fidelity in love, which is evaluated as violating the moral law. The frame is verbalized as the following slots: 1) the agent (traitor, cheater, adulterer/adulteress) is an insidious person who is in a legal relationship with the patient; 2) the act (to cheat on somebody, to commit adultery) is committed in secret and includes marital unfaithfulness and a change of partner; 3) the evaluation of the act and the agent (treacherous, unfaithful, adulterous) is negative. Several slots had no verbal expression but could be explicated from idioms and examples: 1) the patient is the spouse of the agent; 2) the counter-agent is the person the agent enters into an illegal relationship; 3) the result depends on the particular situation.
Correlation of Similarities and Differences in the Croatian and Serbian Languages
Authors: Bagdasarov A. R. , Bychenko A. A.
Published: December 2022

The article introduces a comparative analysis of some interlingual variant formations in the linguistic structures of the Croatian and the Serbian literary languages. The general integration processes that occurred in the Slavic linguistic world in the XIX and the early second half of the XX centuries did not unite individual Slavic languages or their variants. By the end of the XX century, linguistic convergence was replaced by linguistic divergence. After the collapse of the Socialist Federal Republic of Yugoslavia, the new states that arose in the post-Yugoslavian space fixed the status of Croatian and Serbian as official languages. At present, Croatian and Serbian have their own codified norms; they develop and function autonomously and independently in different ethnic cultures and states. The widening gap between the post-Yugoslavian states of Serbia and Croatia contributed to the interlingual divergence between these languages. Their linguistic structure has multiple differences at phonetic, phonological, grammatical, lexical, syntactic, and stylistic levels. This research showed that the most prominent differences occur at the lexical level. As for linguistic standardization and codification, the Croatian language reveals a prescriptive-descriptive approach to language regulation, while Serbian is characterized by a descriptive-prescriptive approach. The authors illustrate this conclusion by various intervariant or equivalent language units from parallel reference books and online discourse.
Translative Linguistics: an Aspectualized Review of Initial Provisions. Part 1. Gnoseology of Translation
Authors: Golev N. D.
Published: December 2022

The article introduces translative linguistics as a special branch in the study of natural languages and describes the history of its development. Translative linguistics uses the methods of quantitative linguistics, combinatorial linguistics, associative grammar, lexicography, etc. It focuses on the same aspects of language as historical grammar, phonetics, political linguistics, etc. The ontology of translational linguistics sees the natural language and its units as its research object. Translation (reserve translation, machine translation, and reverse machine translation) acts as a research method that translational linguistics uses to describe the patterns of the translated language. The author reviews various scientific publications to describe the concepts and terms of translational linguistics. The author uses the method of linguistic logic, which is understood as incorporating a new concept in the traditional system of theoretical linguistic concepts.

Las orquídeas son una de las flores más importantes que se cultivan en Sri Lanka para la exportación y el mercado local. Uno de los principales obstáculos para la expansión del cultivo de orquídeas es el limitado suministro de materiales de plantación de calidad. Las técnicas de micropropagación pueden aplicarse con éxito para la propagación masiva de orquídeas. Pero la micropropagación es costosa, lo que aumenta el coste de producción. Por lo tanto, esta investigación se llevó a cabo para sustituir el costoso agar para el subcultivo in vitro de plántulas de Cattaleya. Las plántulas de Cattaleya de dos meses de edad se subcultivaron en los medios Murashige y Skoog (MS) y Knudson C (KNC) como medios basales. Como agentes gelificantes se utilizaron sagú, sémola, harina de maíz, sémola + agar, harina de maíz + agar. El tratamiento de control se realizó con agar. Los cultivos se mantuvieron en la sala de cultivo. El número de hojas, el número de raíces, la longitud y la anchura de las hojas y el porcentaje de contaminación se registraron a intervalos de cuatro semanas. El sagú y la sémola + agar mostraron un mayor rendimiento y un bajo porcentaje de contaminación como agentes gelificantes alternativos en el medio MS. El sagú, la harina de maíz, el sagú + agar, la sémola + agar y la harina de maíz + agar mostraron mayores rendimientos y bajos porcentajes de contaminación en los medios KNC. Los resultados de este estudio proponen que el sagú, la sémola y la harina de maíz pueden utilizarse como agentes gelificantes alternativos en los medios MS y KNC para las prácticas de subcultivo de orquídeas.
