Biofilia: Aristóteles, Edward o. Wilson y la novela Perdita de Hilary C. Scharper
Authors: González-Vaquerizo Helena
Published: November 2023

En este trabajo se estudia el concepto de biofilia desde una perspectiva humanista, literaria y conservacionista. En primer lugar, se propone adoptar la definición de biofilia de Edward O. Wilson como forma de atracción innata que siente el ser humano por la naturaleza y lo vivo. Esta idea se pone en relación con las distintas formas de filía («amistad, amor») identificadas por Aristóteles en la Ética a Nicómaco. En segundo lugar, se analiza la centralidad del concepto de biofilia en la novela Perdita (2013) de Hilary C. Scharper, una obra que propone la existencia de unos fragmentos perdidos de la Teogonía de Hesíodo y que supone un interesante ejercicio de adaptación del pensamiento científico y humanista a la expresión literaria y mítica.
(Re)construcción identitaria y pertenencia de los mauricianos en la actualidad: el caso de Les Rochers de Poudre d’Or de Nathacha Appanah
Authors: Contreras Pérez Marta
Published: November 2023

A partir de finales del siglo xviii se produjo una gran afluencia de migraciones desde la India hasta Mauricio. Tras la abolición de la esclavitud, los colonizadores británicos buscaron mano de obra barata en los países asiáticos, especialmente en la India. Allí contrataban a trabajadores para labrar los campos de caña de azúcar. Desde entonces existe una gran diversidad cultural, lingüística, religiosa y étnica conviviendo en la isla. Este momento histórico lo relata la autora francófona mauriciana de origen indio, Nathacha Appanah (1973-), en su primera novela, Les Rochers de Poudre d’Or (2003). Emplearemos como corpus de trabajo esta obra literaria con el fin de reflexionar sobre el proceso de (re)construcción identitaria de los migrantes que habitan este territorio. Igualmente, este imaginario se utilizará como marco para teorizar la importancia de la representación y la cohabitación de otras identidades dentro de un mismo espacio geopolítico.

Rise of Anti-Microbial Resistance in India: What is Missing Prevention or Control?
Authors: Tikhute Vishal
Published: November 2023

Antimicrobial resistance (AMR), occurs when microorganisms such as bacteria, viruses, fungi, and parasites evolve in ways that render the medications used to cure the infections they cause ineffective [1]. When the microorganisms become resistant to most antimicrobials, they are often referred to as “superbugs” [1]. AMR is a major public health concern because a resistant infection may kill, can spread to others, and imposes a huge cost on individuals and society [1]. Therefore, this article presents a situational analysis of AMR and advocates for a multi-disciplinary approach to control AMR in India. The most recent and relevant publications on AMR in India were reviewed and analyzed to recommend a comprehensive health policy framework. The study recommends an innovative health policy framework for avoiding emergence, supporting research and development (R&D) for new drugs, and encouraging multi-sectoral coordination. Further amendments to the existing health policy with a targeted approach to prevent the growing epidemic of AMR are required. Failure to do so may cause irreversible damage with high morbidity, mortality, and disability in India.
Evaluation of the Pollution Effect of Abattoir Effluent in River Benue
Authors: Offiono Benjamin
Published: November 2023

Abattoir Effluent could pose a major environmental and health problem to aquatic systems. The long and short term safety and health effect on humans and livestock depend upon the physical and chemical characteristics of the pollutant and exposure to such polluted water system. The Benue River is non-tidal freshwater ecological system located in Makurdi local government area of Benue State, Nigeria. The study is aimed at presenting results of the physical and chemical parameters for the period of April to July 2019. Parameters such as temperature, turbidity, suspended solids, pH, conductivity, dissolved solid, dissolved oxygen, BOD and COD were obtained. Samples were taken at different points in the river within the distance of 200 meters downstream, midstream, upstream and the point source. The concentrations of the parameters were obtained using standard procedures. The results indicate that the water quality parameters like suspended solid (45.2 mg/L), dissolved oxygen (5.2 mg/L), turbidity (24.1 NTU), fell above the standard stipulated by the World Health Organization (WHO), Nigerian Standard for Drinking Water Quality (NSDWQ) and Standard Organization of Nigeria (SON). Statistical analysis was also used to develop a regression equation, the best model gave a correlation coefficient of 0.887 as SS = 133.304 - 0.583SS – 0.837TS – 2.308Temperature. By application of these standard approaches, TDS and EC show strongly positive correlation because the ions from the dissolve solid in water influenced the ability of the water to conduct an elementary current. These two parameters significantly vary among nine sites which are further confirmed by using linear regression. Hence, the water is unsafe for drinking and domestic use. It is recommended that the water should be treated before it can be used for irrigation purpose.
The morphological and genetical characterisation of a native Norway spruce (Picea abies (L.) Karst.) population in the area of Pokljuka mire
Authors: Božič Gregor , Urbančič Mihej
Published: November 2023

Morphometrical and genetical characteristics of two morphologically different sub-populations of spruce trees grown in a frost area of the mire Sijec (altitude 1170 m) on the Pokljuka plateau were studied. The tree height & diameter, needle length & needle volume of 70, approximately 120 to 200 years old trees, were measured. The genetic structure of the two spruce sub-populations were estimated by isozyme analysis on starch gel at 17 polymorphic gene loci. Soil conditions on the research plots examined with a gauge sound and then mapped and investigated in details by lab analyses of soil samples from representative soil profiles. The analysed spruce trees grown on the more productive site belonging to the association Rhytidiadelpho lorei - Piceetum in edge of the mire with mainly automorphic soils were in average 3,8 times taller and thicker than the trees from the extreme site belonging to the association Sphagno girgensohnii - Piceetum. The needle length of these trees was 25,7 % longer and their needle volume 68 % bigger than of the trees from the mire plot on the hydromorphic peat soils. The comparison of the genetic structures has shown distinct differences in frequencies of some alleles and genotypes between the analysed spruce sub-populations.
Aerobic bacteria in holy water from Catholic churches in Slovenia
Authors: Turk Martina , Podgrajšek Vesna , Gostinčar Cene , Gunde-Cimerman Nina
Published: November 2023

Holy water plays an important role in various religions. It is used for baptisms, to bless people, places and objects. In Catholic churches, it is usually offered in the holy water fonts at the entrance of the church. But it is also considered a source of potential pathogens, such as Pseudomonas aeruginosa, Acinetobacter baumanii and enterobacteria. To estimate the potential risk, we studied the composition and antimicrobial resistance of bacteria in holy water from fonts and reservoirs of ten selected Catholic churches in Ljubljana, Slovenia. Bacterial contamination of holy water from fonts was moderate (102 - 105 CFU ml-1), but one to two orders of magnitude higher than in reservoirs, probably due to frequent immersion of fingers in the water. Some genera/species occurred only in fonts (Acinetobacter beijerinckii, A. haemolyticus, Brevundimonas aurantiaca, B. mediterranea, Delftia, Kocuria, Sphingobacterium, Staphylococcus warneri), while few fecal indicator bacteria were isolated. Isolated bacteria have relatively low pathogenic potential, some of them are skin commensals. Bacterial strains isolated in this study were susceptible to antibiotics.While according to our results, the potential of holy water for spreading bacterial infections is modest, to further limit the risks, water should be changed regularly, the fonts cleaned thoroughly, and the water should not be brought in contact with the eyes, ingested or aerosolized and inhaled.

Published: November 2023

Long COVID is a global health problem that impairs patients' functional status. More than 200 reported symptoms have been identified where fatigue, dyspnea, and exercise impairment are most common. This study aimed to describe exercise capacity, fatigue, dyspnea, and lung function in previously non‐hospitalized patients with long COVID, and examine the relationship between exercise capacity and fatigue, dyspnea, and lung function. Sixty‐five patients, 54 women (83%), mean age of 39 standard deviation (12) years, were included and completed spirometry, cardiopulmonary exercise test, stair climbing test (SCT), 30 second sit‐to‐stand test (30STST), and questionnaires regarding fatigue and dyspnea. Fatigue was reported by 95% of the participants, whereas 65% reported severe fatigue, and 66% reported dyspnea. Mean exercise capacity measured with peak oxygen uptake (V̇O2peak% pred.) was ≥85% in 65% of the participants. Mean forced expiratory volume in 1 s. and forced vital capacity were 96.6 (10.7)% and 100.8 (10.9)%, respectively, while reduced diffusion capacity for carbon monoxide (DLCO) was found in eight participants (13%). Reduced V̇O2peak kg−1and increased time on SCT were significantly associated with increased dyspnea and reduced DLCObut not with fatigue, while 30STST was associated with increased fatigue and dyspnea in previously non‐hospitalized patients with long COVID.
Monitoring and evaluation of anesthesia depth status data based on neuroscience
Authors: Bi Yuhua , Huang Junping , Li Mei , Li Siying , Lei Heshou
Published: November 2023

Monitoring and analysis of anesthesia depth status data refers to evaluating the anesthesia depth status of patients during the surgical process by monitoring their physiological index data, and conducting analysis and judgment. The depth of anesthesia is crucial for the safety and success of the surgical process. By monitoring the state of anesthesia depth, abnormal conditions of patients can be detected in a timely manner and corresponding measures can be taken to prevent accidents from occurring. Traditional anesthesia monitoring methods currently include computer tomography, electrocardiogram, respiratory monitoring, etc. In this regard, traditional physiological indicator monitoring methods have certain limitations and cannot directly reflect the patient’s neural activity status. The monitoring and analysis methods based on neuroscience can obtain more information from the level of brain neural activity. Purpose: In this article, the monitoring and analysis of anesthesia depth status data would be studied through neuroscience. Methods: Through a controlled experiment, the monitoring accuracy of traditional anesthesia status monitoring algorithm and neuroscience-based anesthesia status monitoring algorithm was studied, and the information entropy and oxygen saturation of electroencephalogram signals in patients with different anesthesia depth were explored. Results: The experiment proved that the average monitoring accuracy of the traditional anesthesia state monitoring algorithm in patients’ blood drug concentration and oxygen saturation reached 95.55 and 95.00%, respectively. In contrast, the anesthesia state monitoring algorithm based on neuroscience performs better, with the average monitoring accuracy of drug concentration and oxygen saturation reaching 98.00 and 97.09%, respectively. This experimental result fully proved that the monitoring performance of anesthesia state monitoring algorithms based on neuroscience is better. Conclusion: The experiment proved the powerful monitoring ability of the anesthesia state monitoring algorithm based on neuroscience used in this article, and explained the changing trend of brain nerve signals and oxygen saturation of patients with different anesthesia depth states, which provided a new research method for the monitoring and analysis technology of anesthesia depth state data.
The Riddle of the Great-souled eiron. Virtue, Deception and Democracy in the Nicomachean Ethics
Authors: Voß Carlotta
Published: November 2023

Aristotle’s use of the term ‘eironeia’ in the Nicomachean Ethics (NE) appears to be inconsistent: first, he attributes the attitude termed ‘eironeia’ to the great-souled man (megalopsychos), who is defined by his virtuousness, then he classifies ‘eironeia’ as one of the two vices which are central to his account of the virtue of truthfulness. Modern attempts to explain and to solve the “riddle of the great-souled eiron” have not been satisfying. This paper argues that the riddle results from Aristotle trying to reconcile aristocratic values with democratic reality. In the process, some insight will be gained on the concept of the megalopsychos in general, on Aristotle’s notion of the virtue of truthfulness and on his depiction of Socrates. Finally, it is argued that Aristotle’s use of the notion of ‘eironeia’ in the NE bears some resemblance to the use of the notion of ‘irony’ in modern political theory.
Le problème de la compréhension de la dualité de la téléologie d’Aristote comme « but » et « bénéficiaire »
Authors: Dos Santos Nélio Gilberto
Published: November 2023

This study intends to show that the usually given meaning of the teleological dualism τὸ οὗ/τὸ ᾧ of Aristotle’s De anima, understood as “an aim or goal” and “the beneficiary”, does not come from Aristotle, but from a controversial interpretation of the ancient commentators. It originates on the attempt of certain Peripatetics to appropriate the Stoic distinction between “happiness” and “the happy subject” designated as the σκοπός and the τέλος of moral action. After this historical accuracy, we will propose a different reading of the Aristotelian distinction according to the context of De anima as designating the tendency in the individual towards its preservation and use.
Low-temperature relaxation of various samarium phosphate glasses
Authors: Gaafar Mohamed El-Sayed , Marzouk Samir Yousef
Published: November 2023

Glasses constructed, (1 − x) (0.6595P2O5–0.0958ZnO–0.2447PbO) · xSm2O3 with x = 0.00, 0.0045, 0.0089, 0.0132, and 0.0261 mol%, had been created to investigate the attenuation of longitudinal ultrasonic waves at 2, 4, 6, and 14 MHz frequencies between 120 and 300 K. At a variety of temperatures, clear peaks of a large absorption curve have been seen. These peaks are dependent on the structure of the glass as well as the switching frequency. Maximum peaks have been shown to shift to higher temperatures, and the increase in overall frequency points to the presence of some kind of relaxation process. A thermally induced relaxation process is responsible for producing a calm approach, which has been identified as a result of this mechanism. A quiet approach has been defined as a consequence of a thermally triggered relaxation mechanism. The variance of the mean energy of activation of the mechanism counts on primarily the amount of Sm2O3 mol%. Such dependency has been evaluated based on the loss of normal linear solid form, attaining low dispersion, and a large allocation of Arrhenius kind relaxation through temperature-autonomous relaxation power. The measured acoustical energy of activation values have been quantifiably represented based on the number of loss centers (amount of oxygen atoms that now move at a double-well potential).

-person noncooperative differential games. More precisely, due to a preorder induced by a convex cone on a real linear normed space, we define a new concept called ordering stability of equilibria against the perturbation of the right-hand side functions of state equations for the differential game. Moreover, using the set-valued analysis theory, we present the sufficient conditions of the ordering stability for such differential games.

Published: November 2023

In order to solve the problem of accumulation of glass waste seriously affecting people’s life safety, it is of great significance to study the crushing mechanism of glass waste. At present, no scholars have studied and analyzed the waste glass head, especially the single-axis compression test. In this study, a three-dimensional waste glass is established by discrete element software, and the single-axis compression characteristics of waste glass at different loading rates are analyzed by using Hertz contact model provided by the software. The results show that the loading rate is influenced by the equilibrium iteration rate and stress loading step length. The study also analyzes the pressure plate extruding waste glass in different positions. Finally, the stress–strain strength of five groups of waste glass under the action of uniaxial compression is analyzed, and the stress strength is between 0.3 and 0.56 MPa. This study provides a theoretical basis for further study of the breakage characteristics of waste glass under composite loading.
Mechanisms of chemical vapor generation by aqueous boranes for trace element analysis: a rather long and unfinished story
Authors: D’Ulivo Alessandro
Published: November 2023

This paper reports a summary of the studies on the mechanisms that govern the generation of hydrides and other volatile species through reaction with aqueous boranes (CVG). This derivatization reaction has been used since the early 1970s for elemental determination and speciation from the trace level down to the ultratrace level and below. An IUPAC project, concluded in 2011, reported on the mechanisms of hydrogen transfer from borane to the analytical substrate and served to remove erroneous concepts that had dominated CVG until the early 2000s. Following the conclusion of the IUPAC project, many studies have been published on the mechanisms of CVG under conditions approaching those of analyzes of real samples. These studies included the definition of more general reaction models, which valid under non-analytical conditions, the mechanism of action of additives and interferences in CVG of volatile hydrides. In addition to the analytical utility for CVG, the results represent a contribution to the knowledge of the chemistry of aqueous boranes. Other studies will be necessary to clarify still unknown aspects, among them the identity of volatile transition metal species formed by reaction of metal ions with aqueous boranes.

Published: November 2023

Recent research has explored the potential of rice husk biochar as a low-cost adsorbent for the removal of contaminants from aqueous solutions, including aldrin, mercury (Hg2+), lead (Pb2+), and cadmium (Cd2+). Experimentation involved adding varying doses of biochar to wastewater with different contamination levels, agitating the mixture for 60 min, and filtering the solutions for analysis. The experiment revealed impressive removal efficiencies: 100% for aldrin, 99.92% – 99.99% for Hg2+, 95.90% – 99.52% for Pb2+, and 88.60% – 99.46% for Cd2+. In binary and quaternary mixtures, Hg2+ showed higher removal efficiency than Pb2+ and Cd2+, with the exception of aldrin. The adsorption order was identified as aldrin > Hg2+ > Pb2+ > Cd2+. The Freundlich adsorption isotherm best described heavy metals in the mono and quaternary component adsorption, while the Langmuir adsorption isotherm was a better fit for the binary component. Consequently, the study highlights rice husk biochar as an efficient, sustainable, and environmentally friendly option for wastewater treatment.
Study on the seismic performance of through-tenon joints with pullout tenon gaps between mortise and tenon shoulder
Authors: Huan Junhong , Sun Zemeng , Guo Xiaodong , Chu Tianyang , Zhou Xiaoyi , Wang Wei , Yang Yating
Published: November 2023

Through-tenon joints are widely used in ancient timber buildings. To study the influence of the gaps between mortise and tenon shoulder on the seismic performance of through-tenon joints, a 1:3.52 scaled model was constructed and used for low cyclic loading test. Finite element analysis was conducted to study the mechanical behavior of the through-tenon joint. The seismic performance parameters of the model such as moment-rotation hysteresis curves, envelope curves, degradation of rigidity, and energy dissipation capacity were compared. The analyses showed similar changing characteristics, which indicated that the finite element analysis results were reliable. Based on the results, 7 through-tenon joint finite element analysis models with different gaps between mortise and tenon shoulder were established. The seismic performance of each of the through-tenon joints with different gaps between mortise and tenon shoulder were studied. The moment-rotation hysteresis curve of the through-tenon joint had an obvious pinching effect, and the through-tenon joint had good rotational loading capacity and good deformation ability. The peak rotational loading capacity, initial stiffness, and energy dissipation capacity of the joint decreased, while the gap between mortise and tenon shoulder increased.

Researchers have recently been interested in employing nanoparticles (NPs) obtained from herbal extracts through green synthesis for various applications. This study investigated the detoxification of aflatoxins, which are toxic substances produced by molds Aspergillus flavus and Aspergillus parasiticus. The present work examined the levels of aflatoxins in hazelnut and peanut puree. Turkish black tea extract (BTE), Turkish green tea extract (GTE), green synthesized black tea-based iron oxide nanoparticles (BTFeONPs), and green tea-based iron oxide nanoparticles (GTFeONPs) were produced for aflatoxin removal. Characterizations and various antioxidant and antimicrobial activities of the tea extracts and iron oxide nanoparticles (FeONPs) were investigated. The aflatoxin levels of hazelnut puree used for this study were 6.57 ± 0.06 µg/kg for aflatoxin B1 and 13.03 ± 0.16 µg/kg for total aflatoxin, whereas the aflatoxin levels of (AFLB1) peanut puree were 7.79 ± 0.15 µg/kg for AFLB1 and 15.21 ± 0.12 µg/kg for total aflatoxin. Using soluble BTE resulted in a 40 to 50% decrease in aflatoxin levels in hazelnut and peanut purees, while soluble GTE led to a 30 to 45% decrease. Meanwhile, using BTFeONPs and GTFeONPs resulted in a 33 to 48% and 40 to 50% decrease, respectively, in aflatoxin levels in hazelnut and peanut purees.

Published: November 2023

For better learning achievements in a networked society the great variety of virtual learning environments (VLE) is being developed and used. VLE is going to be integrated into Lithuanian education. One of the steps during the integration is VLE localization into Lithuanian.In this paper the main aspects of VLE localization are presented. Since most of modern VLEs are webbased, their localization is based not only on common software localization principles, but also onsweb site localization specifics. Two open source VLEs –  ``  `  ATutor“ and  `` ` Moodle“ – are analyzed. Basic locale items (as characters encoding, date and time formats, calendar format, parameters in localization strings, etc.) used in VLE, are discussed, their adaptation to Lithuanian locale is evaluated. Additional requirements for VLE localization are presented.As a result of the analysis, not sufficient VLE internationalization level has been noticed. Some locale items, used in VLE, are not compatible with Lithuanian locale. To solve these problems, VLE source should be modified, thus open source VLEs have an advantage from localization point of view.

Анотація. Ця стаття присвячена високошвидкісним літальним апаратам (ЛА), а конкретно до поверхонь, що управляють, таким як аеродинамічне кермо, крила і стабілізатори, які застосовуються на таких ЛА. При русі в щільних шарах атмосфери, особливо на великих числах Маха, передня частина аеродинамічного керма (АДР) піддається великим механічним, тепловим і динамічним навантаженням. Обгар передньої кромки керма призводить до зміни його форми геометрії і площі, зміни його масово-габаритних характеристик. Це призводить у результаті до погіршення керованості виробу, особливо на кінцевій ділянці польоту, коли має бути досягнута мета польоту, визначувана кінцевими параметрами руху. Метою цієї статті є аналіз існуючих конструкцій, а також пошук конструкції, що максимально усуває вказані недоліки. Постановка завдання полягає в оптимізації конструкції даних АДР за критеріями надійності, керованості, мінімальної ваги, габаритних і інерційних характеристик. Оскільки надійність керованості залежить від останніх трьох критеріїв, то оптимізація повинна здійснюватися за рахунок поліпшення цих критеріїв. Розглянута існуюча конструкція аеродинамічного керма, яка дозволяє застосувати її в літальних апаратах, які рухаються в щільних шарах атмосфери при швидкостях, що перевищують число Маха, а також конструкція, яка дозволяє підвищити надійність керованості ЛА і уникнути обгорання передньої кромки АДР. Існуючі конструктивні рішення не забезпечують повною мірою, необхідній ефективності. Відсутність захисту від теплових навантажень забезпечується погіршенням вагових, габаритних і інерційних характеристик АДР і приводу, оскільки вимагає застосування додаткового теплозахисного покриття. Тому актуальний пошук технічних рішень, що усуває ці недоліки, на шляху підвищення надійності керованості за рахунок зниження вагових, габаритних і інерційних характеристик АДР. Приведений порівняльний аналіз і особливості цих конструкцій, а також викладені основні проблемні питання, що виникають при проектуванні приведених варіантів конструкції аеродинамічного руля.

Анотація. Зараз у бойових діях різного масштабу особливо важливими стали операції з використанням всіх типів ракет. Одночасно з цим збільшується значення заходів протидії проти таких ракет. Для успішного виконання бойових завдань необхідно передбачити та ефективно протидіяти різним заходам вірогідного противника при застосуванні твердопаливних оперативно-тактичних ракет. Одним з перспективних підходів є зміна траєкторії ракети на різних етапах її польоту за допомогою систем керування вектором тяги твердопаливного двигуна. У даній роботі розглядаються різні методи керування вектором тяги оперативно-тактичних ракет на початковій ділянці польоту з метою протидії системам протиповітряної оборони противника. Описано такі методи керування, як векторне керування з використанням засобів автоматичного керування, програмоване керування вектором тяги, метод внутрішнього керування вектором тяги та гібридне керування вектором тяги. Кожен з цих методів має свої переваги та недоліки і відкриває широкі можливості для подальшого технічного вдосконалення. Різні методи керування вектором тяги можуть бути використані залежно від ситуації на полі бою та конкретної ділянки польоту. Застосування цих методів дозволяє підвищити маневреність та непередбачуваність руху ракети, ускладнити завдання системам протиповітряної оборони противника та підвищити ймовірність успішного виконання бойового завдання. Виконання наведених вимог є пріоритетними у сучасних умовах, що робить перспективною подальшу працю за згаданими напрямками дослідження.  Загальноприйняті рекомендації щодо вибору методу керування вектором тяги на початковій ділянці польоту включають аналіз характеристик систем протиповітряної оборони противника, оцінку потенційних загроз та вибір оптимальної стратегії керування. Висновки даної роботи можуть бути використані для практичного застосування відповідних методів керування вектором тяги твердопаливних оперативно-тактичних ракет у реальних умовах бойових дій. Збільшення розуміння та ефективного використання цих методів сприятиме поліпшенню стратегій та тактик ведення бойових дій і допоможе забезпечити перевагу у конфліктах з вірогідними противниками.

Abstract. The article presents the results of experimental investigation of the ST-40M Hall thruster modification developed by the Space Electric Thruster Systems (SETS). The thruster used a new filament hollow cathode with an emitting insert made of lanthanum hexaboride (LaB6). The use of a new hollow cathode made it possible to study the thruster’s parameters in the discharge power range of 300 – 550 W. The investigation was carried out using a stabilized voltage supply as a discharge power supply. As a result of experimental investigation, the current-voltage characteristics of the discharge in the accelerating channel of the thruster were obtained at fixed values of the anode’s mass flow rate of the working gas - xenon. The experimental dependences of thrust on the anode’s mass flow rate of the working substance and the discharge voltage, as well as the dependences of the specific impulse and thruster efficiency on the discharge voltage, are obtained. Experimental studies have shown that with a change in the discharge voltage in the range of 250 – 400 V and a change in the mass flow rate of the working gas in the range of 0.9 – 2.2 mg/s, the thruster provides a thrust value of 12 – 33 mN, a specific impulse value of 1200 – 1800 s, and the maximum value of the anode’s efficiency is 48 – 52%. The article also contains oscillogramsillustratingtherepeatedprocessofthethrusterstarting. Experimentalinvestigationofthemodified thruster ST-40M with the new hexaboride hollow cathode showed a significant improvement in thruster parameters compared to the prototype parameter before modification. In the process of experimental investigation, it was found that in some modes of the thruster operation, significant fluctuations in the discharge current occur, which led to a significant decreasing in the thruster parameters. For a more accurate clarification of the nature and parameters of the discharge current oscillations, it is necessary to conduct additional studies. The obtained experimental parameters of the modified ST-40M thruster made it possible to determine the values of its optimal parameters for various space missions.

Анотація. Металеві ткані сітки з квадратними чарунками є основним робочим елементом капілярних роздільників фаз рідина-газ. Капілярні роздільники фаз використовуються у баках космічних літальних апаратів для утримання палива у визначених місцях баків в умовах космічної мікрогравітації. Сепарація рідини та газу на сітках відбувається завдяки дії сил поверхневого натягу на поверхні розділу фаз всередині чарунок сітки. Зменшити розміри чарунок сіток, що промислово виготовляються, можна за допомогою методу деформування структури плетення їх волокон. Розроблено методику розрахунку еквівалентного капілярного діаметру пор сіток з деформованою структурою плетіння. Розроблена методика використовує математичні моделі, які враховують тип плетіння сітки (полотняний, саржевий), кут переплетення волокон сітки та крайовий кут змочування її поверхні з рідиною. Також методика використовує алгоритм врахування технологічних похибок при виготовлені сітки. За допомогою розробленої методики отримано графічні залежності еквівалентного капілярного діаметру пор сіток з квадратними чарунками мікронних розмірів, що виготовляються промислово від кута переплетення їх волокон внаслідок деформації. Отримана методика та залежності можуть бути використані при проектуванні капілярних роздільників фаз у паливних баках космічних літальних апаратів, а також при проектуванні капілярних пристроїв інших технічних систем, що мають у своєму складі сітки з деформованою структурою плетіння, а також недеформовані сітки з квадратними чарунками, такі як теплообмінники, фільтри, змішувачі, хімічні реактори та ін. Наукова новизна отриманих результатів полягає у розроблені нового алгоритму розрахунку еквівалентного капілярного діаметру пор сіток з деформованою структурою плетіння. Отриманий алгоритм враховує тип плетіння сітки (полотняний, саржевий), вплив крайового кута змочування матеріалу сітки і палива, а також похибки при виробництві сітки.

Published: November 2023

Este estudo realizou uma revisão sistemática da literatura brasileira e internacional publicada entre 2015 e 2020 sobre bibliométricos, operacionalização teórica e metodológica e direcionalidade de efeitos das relações entre a parentalidade e o temperamento infantil em estudos sobre crianças de quatro a sete anos. A busca nas bases de dados BVS-Psi, Portal Regional da BVS, MEDLINE, Academic Search Premier, SocINDEX, SCOPUS, ScienceDirect, PsycInfo e PsycArticles, a partir das palavras-chave “parenting”, “child temperament” e “infant temperament” resultou em 24 estudos selecionados para análise. Predominaram pesquisas norte-americanas, com delineamento quantitativo, uso de questionários e mães respondentes. O referencial teórico-metodológico utilizado para avaliar a parentalidade mostrou-se diversifi cado, enquanto o Modelo Psicobiológico destacou-se na avaliação do temperamento. Constatou-se que temperamento e parentalidade possuem associação direta e indireta e os efeitos dessa relação reverberam no desenvolvimento infantil. Destaca-se a importância de programas de intervenção para a promoção da parentalidade positiva e o desenvolvimento de habilidades regulatórias infantis.
Foco prosódico e clivagem no processamento de elipses no português brasileiro
Authors: Alves Fonseca Aline , Oliveira da Silva Andresa Christine , Greco Carvalho Júlia , Campos e Souza Marcella
Published: November 2023

Este trabalho investiga a influência da marcação de foco prosódico contrastivo e do que chamamos de “foco sintático” por meio da clivagem, na resolução de ambiguidades em estruturas elípticas replacive: “Durante o ensaio da orquestra, (foi) o violinista (que) impressionou o maestro, não o solista”. Esta pesquisa foi inspirada em Carlson (2015), que investigou sentenças similares em inglês. Conduzimos duas atividades experimentais com uma combinação de 7 condições experimentais de clivagem e foco prosódico. Após ouvirem as sen­tenças, os participantes (N=66) respondiam perguntas como: “O que aconteceu em...?”. A resposta podia ser uma interpretação de objeto: “Ninguém impressionou o solista”; ou uma interpretação de sujeito: “O solista não impressionou ninguém.” Os resultados apontam que ambas as estratégias de focalização (foco prosódico e clivagem) influenciaram o aumento da interpretação de sujeito. Quando as pistas de focalização são conflitivas, a clivagem exerceu um papel decisivo na interpretação final. Nossos resultados estão alinhados com os de Carlson (2015) para o inglês. O foco prosódico desempenha um importante papel na resolução de ambiguidades, como em Schafer et al. (1996). No entanto, conforme Kiss (1998), a clivagem transmite um foco contrastivo e exaustivo para a sentença, sendo, portanto, uma pista de desambiguização mais efetiva do que outras.

In this study, we sought to examine firewood use patterns in artisanal ceramic production by a quilombola community in the context of forest scarcity in Northeastern Brazil. This article aimed to answer the following questions: (1) Is the firing of ceramic products related to the perceived quality, diversity, or plant part used as firewood? (2) Does the diversity of plants used as firewood vary according to the age and gender of artisan potters? (3) What are the physical and energetic properties of the species most commonly used as firewood? Our main findings were that resource availability and accessibility seem to be the determining factors of firewood use. Exotic species were widely used. Variables commonly described as predictors of firewood diversity, such as age and gender, were not relevant in the context of forest scarcity. The most used exotic species have good physicochemical properties and can be a viable alternative to meet the firewood demand of ceramic production. However, the results showed that these species are more readily available to potters who have access to private woodlands. Therefore, in the studied context, we suggest the need for conservation strategies that foster the creation of energy forests composed of exotic species and, in parallel, promote conservation and reforestation actions aimed at native species.
