Organization Studies and the Legal Person
Authors: Brunsson Nils
Published: April 2024

The social construction of legal persons developed in the Western world about one thousand years ago has historically influenced the construction of organizations, including monasteries, guilds, cities, universities, states, associations, and businesses. Yet the notion of legal person was not present in influential, early definitions of organizations; rather organizations were understood as systems of interacting physical persons. This understanding is problematic in several respects, whereas the notion of legal person helps to explain many fundamental characteristics of organizations. Furthermore, a definition of organizations inspired by the notion of legal person makes it easier to distinguish clearly among the three phenomena that constitute the main objects of organization studies: organizations, organizing, and the organized. A clearer distinction among three concepts has the potential to revive old questions and generate new questions for organizational research.

Published: April 2024

In this investigation, the fractional Hirota–Satsuma coupled Korteweg–de Vries (KdV) problem is solved using two modern semi-analytic techniques known as the Aboodh residual power series method (ARPSM) and Aboodh transform iteration method (ATIM). The two suggested approaches are briefly explained, along with how to use them to solve the fractional Hirota–Satsuma coupled KdV problem. Some analytical approximate solutions for the current problem are derived using the proposed techniques until the second-order approximation. To ensure high accuracy of the derived approximation, they are analyzed numerically and graphically and compared with the exact solutions of the integer cases. The offered techniques demonstrate more accuracy in their outcomes compared to other alternatives. The numerical results show that ARPSM and ATIM are highly accurate, practical, and beneficial for solving nonlinear equation systems. The current results are expected to help many physics researchers in modeling their different physical problems, especially those interested in plasma physics.
Beyond cemeteries – excavation of a settlement of Poieneşti-Lucaşeuca Culture in Ivancea, Republic of Moldova
Authors: Meyer Michael , Munteanu Octavian , Iarmulschi Vasile , Schatte Torben
Published: April 2024

The Poieneşti-Lucaşeuca-culture (late 3rd to second half of the 1st century BC), which is distributed in the forest steppe between the east Carpathian Mountains and the river Dniestr, is seen as the result of an immigration of groups from the Jastorf area in North-East Germany. This concept is based on cemeteries: both the form of the grave4s and their material culture (ceramics, jewellery, costume) are foreign in the area, but show clear connections to the North and the North-West. Up to now large settlement excavations are missing that would allow for an evaluation of that concept based on settlement and economic structures as well as on the material culture of everyday life. The project that is presented here with first results, aims to that desideratum. With surveys and test excavations as a starting point on different sites in Central part of Republic of Moldova, the authors are excavating the Poieneşti-Lucaşeuca settlement of Ivancea-Sub Pădure on a large scale. The project is funded by Deutsche Forschungsgemeinschaft.

The paper presents first results like different post buildings and pit dwellings, the spectrum of small finds and a selection of the numerous ceramics including greek imports, and discusses the connectivity that becomes visible. The post buildings have no regional parallels and seem to have the best parallels in the Northwest. In opposite to that the small finds show a broad entanglement especially to the south and West and thus contradict the evidence from the grave. Also, in opposite to the graves the settlement ceramics show clear regional traditions, bus also relations to the North and the Northeast.

Published: April 2024

Objectives: This study was aimed at comparing the “late catch-up” phenomenon between the BuMA Supreme bioresorbable polymer sirolimus-eluting stent and the XIENCE stent through serial optical coherence tomography (OCT) at within 2 months and 2 year follow-ups.

Methods: A total of 49 of 75 patients from the PIONEER-II study were enrolled in a 2 year OCT follow-up study; 44 patients with 50 lesions were included in the statistical analysis. The primary endpoints were neointimal thickness and late luminal loss (LLL) after stent implantation.

Results: The stenosis diameter, and minimum in-stent or in-segment diameter, did not significantly differ between the BuMA Supreme and XIENCE arms at within 2 months and 2 year follow-ups. The strut neointimal coverage and thickness were greater in the BuMA group than the XIENCE group at the 1 and 2 month follow-ups (P = 0.044 and P = 0.010, respectively) but not at the 2 year OCT follow-up. Neither early luminal loss at the within 2 months follow-up (P = 0.849) nor LLL at the 2 year OCT follow-up (P = 0.613) showed differences between device arms. No significant differences in imaging and clinical endpoints were observed between device arms at follow-up.

Conclusions: The BuMA Supreme stent’s faster re-endothelization with no “late catch-up” phenomenon has potential advantages over the XIECE stent for patients with coronary artery disease and high bleeding risk because it decreases the duration of dual antiplatelet therapy.

Published: April 2024

Forebrain neurons deprived of activity become hyperactive when activity is restored. Rebound activity has been linked to spontaneous seizures in vivo following prolonged activity blockade. Here, we measured the time course of rebound activity and the contributing circuit mechanisms using calcium imaging, synaptic staining, and whole-cell patch clamp in organotypic slice cultures of mouse neocortex. Calcium imaging revealed hypersynchronous activity increasing in intensity with longer periods of deprivation. While activity partially recovered 3 d after slices were released from 5 d of deprivation, they were less able to recover after 10 d of deprivation. However, even after the longer period of deprivation, activity patterns eventually returned to baseline levels. The degree of deprivation-induced rebound was age-dependent, with the greatest effects occurring when silencing began in the second week. Pharmacological blockade of NMDA receptors indicated that hypersynchronous rebound activity did not require activation of Hebbian plasticity. In single-neuron recordings, input resistance roughly doubled with a concomitant increase in intrinsic excitability. Synaptic imaging of pre- and postsynaptic proteins revealed dramatic reductions in the number of presumptive synapses with a larger effect on inhibitory than excitatory synapses. Putative excitatory synapses colocalizing PSD-95 and Bassoon declined by 39 and 56% following 5 and 10 d of deprivation, but presumptive inhibitory synapses colocalizing gephyrin and VGAT declined by 55 and 73%, respectively. The results suggest that with prolonged deprivation, a progressive reduction in synapse number is accompanied by a shift in the balance between excitation and inhibition and increased cellular excitability.
Implementation of marine CO2 removal for climate mitigation: The challenges of additionality, predictability, and governability
Authors: Bach Lennart T. , Vaughan Naomi E. , Law Cliff S. , Williamson Phillip
Published: April 2024

Achieving net zero CO2 emissions requires gigatonne-scale atmospheric CO2 removal (CDR) to balance residual emissions that are extremely difficult to eliminate. Marine CDR (mCDR) methods are seen increasingly as potentially important additions to a global portfolio of climate policy actions. The most widely considered mCDR methods are coastal blue carbon and seaweed farming that primarily depend on biological manipulations; ocean iron fertilisation, ocean alkalinity enhancement, and direct ocean capture that depend on chemical manipulations; and artificial upwelling that depends on physical manipulation of the ocean system. It is currently highly uncertain which, if any, of these approaches might be implemented at sufficient scale to make a meaningful contribution to net zero. Here, we derive a framework based on additionality, predictability, and governability to assess implementation challenges for these mCDR methods. We argue that additionality, the net increase of CO2 sequestration due to mCDR relative to the baseline state, will be harder to determine for those mCDR methods with relatively large inherent complexity, and therefore higher potential for unpredictable impacts, both climatic and non-climatic. Predictability is inherently lower for mCDR methods that depend on biology than for methods relying on chemical or physical manipulations. Furthermore, predictability is lower for methods that require manipulation of multiple components of the ocean system. The predictability of an mCDR method also affects its governability, as highly complex mCDR methods with uncertain outcomes and greater likelihood of unintended consequences will require more monitoring and regulation, both for risk management and verified carbon accounting. We argue that systematic assessment of additionality, predictability, and governability of mCDR approaches increases their chances of leading to a net climatic benefit and informs political decision-making around their potential implementation.
CO2 fluxes of vegetation in the Greenbelt of Ontario and increased net ecosystem emissions associated with its removal
Authors: Madsen Sabrina , Wu Dien , Halim Md Abdul , Wunch Debra
Published: April 2024

The fluxes of carbon dioxide (CO2) to and from vegetation can be significant on a regional scale. It is therefore important to understand the biogenic fluxes of CO2 in order to quantify local carbon budgets. The Greenbelt of Ontario is a protected region of cropland and natural vegetation surrounding the Greater Toronto and Hamilton Area (GTHA) in Ontario, Canada. Recently, changes were proposed to the Greenbelt, including the removal of 2,995 ha (7,400 acres) of protected land to be replaced with housing. In this study, we estimate the biogenic CO2 fluxes of the entire Greenbelt as well as the areas that were proposed for removal by using a modified version of the Solar-induced fluorescence for Modeling Urban biogenic Fluxes vegetation model. We find that, on average, the entire Greenbelt has a net sequestration of 9.9 ± 6.4 TgCO2 each year, where the uncertainty represents half of the interannual variability plus error from the individual years, for the years 2018–2020. The net amount of CO2 absorbed by the Greenbelt is roughly equivalent to a fifth of the annual human-made emissions reported for the entire GTHA. The areas proposed for removal are found to have a net sequestration of 0.0061–0.031 TgCO2 annually. During construction, these lands will remain barren, and the soil will continue to emit CO2, thus changing the area from a net sink to a net source of CO2. For a 3- to 5-year construction period, this soil efflux would result in net ecosystem emissions of 0.314 ± 0.078 TgCO2, in addition to the net sequestration lost by removing the original vegetation (−0.077 ± 0.035 TgCO2). This results in a net difference in biogenic CO2 fluxes of 0.390 ± 0.083 TgCO2, which is equivalent to the average CO2 emissions of roughly 85,000 gasoline passenger vehicles over the course of a year. In addition to biogenic fluxes, there will be CO2 emissions associated with the construction of the proposed single-family housing developments as well as larger per capita emissions associated with low-density housing compared to creating higher density housing using less land.

Published: April 2024

The article presents the results of analytical research of the latest domestic scientific works on the problems of foreign language professional communicative competence formation. The evolution of the purpose and content of the formation of foreign language professional communicative competence of future professionals is disclosed. It is established that the general goal of foreign language training for professional communication is the development of active foreign language competence in everyday, business and professional situations, and professionally oriented intercultural communicative competence of future professionals is defined as the ultimate guideline for achieving this goal. This competence consistsof five system components: communicative, socio-cultural, professional, educational and methodological. Innovations in technological support in the course of training students in higher education institutions for future professional communication are highlighted, including the interdisciplinarity of the course "Foreign language for professional orientation", which introduces the 1-2 course students into future professional activity and motivates to further improve foreign language professional competence; shifting the emphasis from the transforming the information on the formation of skill to acquire knowledge independently and use them in educational and professional activities effectively; a significant reduction of the number of auditorium classes, which is associated with the formation of students’ skill to acquire knowledge independently and apply it in practice efficiently; preparing students for independent study of a foreign language for further professional selfimprovement, that is for independent study.
FEATURES OF THE ORGANIZATION OF DIFFERENTIATED EDUCATION IN THE PRIMARY SCHOOL OF THE NEW UKRAINIAN SCHOOL
Authors: Kilichenko Oksana
Published: April 2024

The article reveals the peculiarities of the implementation of differentiated education in the educational process of primary school. It is noted that each child is a unique individual with unique natural gifts, psychological and physical capabilities, different levels of adaptation to learning. The refore, it is necessary to introduce differentiated learning into the educational process, which we consider as a specially organized educational activity of younger schoolchildren, in the process of which, with the help of taking into account individual characteristics, the selection of forms, techniques and means of learning, there is a direction towards the optimal intellectual development of each child in accordance with his typological characteristics. In order to determine the typification of primary education students, we analyzed the types of learning abilities of students, used the level assessment of educational achievements of primary education students and the typology developed by V.O. Sukhomlynskyi about the division of schoolchildren into groups and the choice of methods of managing their educational process, and used observation of students' educational activities, diagnostic methods, questionnaires, test tasks, and creative tasks. The stages of the implementation of differentiated education in the educational process of primary school are specified, which correspond to the stages of lesson organization and include checking the self-training of students of primary education, preparing them to learn new knowledge during the lesson, initial verification of awareness and understanding of new material, consolidation, generalization and systematization knowledge, instruction on self-training tasks. Attention is drawn to the fact that the use of differentiated education is worthwhile not only during the lessons in primary classes, but also in the process of self-training of students at home. The directions of differentiation of the learning process of third-grade students of the New Ukrainian School have been determined. Current techniques for organizing differentiated education in the third grade of the New Ukrainian School have been selected. Pedagogical conditions for the effective implementation of differentiated education in the educational process of primary school are analyzed.
Grandsons of Grandfather Fyodor Nechaev: Pedigrees of Intelligence in the Field of Genealogy of F. M. Dostoevsky (from the Additions to “The Chronicle of the Generations of Dostoevskys”)
Authors: Drobyshevskaya Inga , Tikhomirov Boris
Published: April 2024

The article presents the results of archival research devoted to the study of the Moscow branch of the family tree of Fyodor Mikhailovich Dostoevsky. The object of consideration was the generation of the grandchildren of the grandfather of the writer Fyodor Timofeevich Nechaev: the Dostoevskys (the children of Maria, his daughter from his first marriage), the Shers and the Stavrovskys (the children of the daughters of F. T. Nechaev from his second marriage — Olga and Ekaterina). Biographical data about the relatives and cousins of F. M. Dostoevsky were extracted from parish and consistory metric books stored in the Central State Archive of the City of Moscow. With a few exceptions (Mikhail, Andrey), metric records of the birth of the writer's siblings are being introduced into scientific circulation for the first time; in some cases, archival documents allowed correcting inaccuracies that were present in the biographical literature about Dostoevsky. Of the thirteen Sher brothers and sisters, male and female cousins of the writer, the names of seven were not previously mentioned even in the fundamental “Chronicle of the Generations of Dostoevskys” (2012). Of the seven Stavrovsky brothers and sisters, two were also named for the first time. Metric birth records are provided for all twenty of these relatives of Dostoevsky; for those who died in infancy, there are also death records. In four cases, the article published metric records of the wedding of the writer’s male and female cousins. In conclusion, the importance of biographical information about the Shers and the Stavrovskys is emphasized for the study of such an important event in the life of F. M. Dostoevsky in the 1870s, as was the litigation over the inheritance of A. F. Kumanina, the writer's mother's sister and half-sister of Olga Sher and Ekaterina Stavrovskaya (the so-called “the Kumanin heritage case”).
“On Saturdays We Went to Take Lessons in Mathematics to Lamovsky”: Alexander Mikhailovich Lamovsky and the Dostoevsky Family
Authors: Davletbaeva Varvara , Emchenko Elena
Published: April 2024

Alexander Mikhailovich Lamovsky (Lomovsky), a well-known mathematics teacher in Moscow and the founder of the Russian Hunting Club, has been interacting with the Dostoevsky family for many years. He was a friend of F. M. Dostoevsky at L. I. Chermak’s boarding school. In the 1830s and 1840s Lamovsky also taught mathematics to all the Dostoevsky brothers; he continued to communicate with Fyodor Mikhailovich, having become one of the leading teachers at the Konstantinovsky Land-Surveying Institute. The article presents the data from A. M. Lamovsky’s formulary list dated April 27, 1850, as well as information about him and his family from little-known essays, obituaries and archival documents. These materials made it possible to describe the pedagogical and official activities of A. M. Lamovsky, to determine the attitude towards him not only of people close to him, but also of pupils and teachers of the Land-Surveying Institute. Thanks to his high professionalism, he became the right-hand man of both A. L. Apukhtin (the director of the Konstantinovsky Land-Surveying Institute) and M. N. Muravyev, a trustee of this Institution. Noting Lamovsky’s professional and public achievements, the authors of the article pointed out that Lamovsky became one of the few friends of Dostoevsky at the Chermak boarding school with whom the writer met later on in life: they may have seen each other in the 1860s and 1870s during Dostoevsky’s stay in Moscow. The writer noted the surname “Lamovsky” in his notebook of 1862–1864, intending to use his friend’s hunting story “about quails” in the story “The Double,” but did not do it due to a lack of time for a cardinal revision of the work. This untold story has remained a mystery in Dostoevsky’s biography and creative history.
Terminological Thesaurus of the Gospel Text by Dostoevsky: Сorpus Analysis and Interpretation Results
Authors: Borisova Valentina
Published: April 2024

The article presents the integrated results of the corpus analysis and interpretation of the terminological dictionary from 700 articles published in the “Problems of Historical Poetics” journal from 1990 to 2021 Based on this data and taking into account the rich lexicographic tradition that reflects the author’s original or thematic terminology — from Antony Khrapovitsky’s “Dictionary to the works of Dostoevsky” (1921) to recent thesaurus-type dictionaries, a thesaurus of the gospel text by F. M. Dostoevsky is compiled. It is a conceptual apparatus that representatively reflects the current state of the study of the writer’s gospel text using terms and concepts that belong to the spheres of general historical poetics and ethnopoetics, theology and philosophy. Dictionary entries devoted to such key concepts of Russian literary criticism of the 21st century as “historical poetics,” “ethnopoetics,” “gospel text,” etc. are given as illustrative examples. The article concludes that this dictionary has promising applied value for solving educational and scientific problems.
Lateral-Torsional-Roll Response of Long Precast Concrete Girders: Uncracked Buckling Load
Authors: Galik William D. , Wiebe Richard , Stanton John F.
Published: April 2024

Lateral buckling of precast and prestressed concrete girders that are not fully restrained against twisting rota¬tions at their ends may occur during lifting and handling. Typically, the critical load at which this instability oc¬curs has been estimated by ignoring torsional deforma¬tions. Although that approach permits a closed-formed solution, it is unconservative. This study includes the torsional deformations and develops a series solution for the simplest case of an end-supported girder. The solu¬tion is then extended to include overhangs. A balance between accuracy and usability is struck by truncating to a one-mode solution. By comparing with two known special cases, the first term is found to be sufficiently accurate while clearly illustrating the effect of torsional flexibility on girder stability. Accounting for torsional deformations reduces the predicted buckling load by an amount that can be conveniently defined with a knockdown factor applied to the traditional buckling load that ignores torsion. In this sense, the effect of torsion is separated from lateral bending. Downward (major-axis) deflection improves stability, whereas that net upward camber does the op¬posite. Use of lightweight concrete reduces the safety factor against lateral buckling.
Experimental Investigation of Multiple-Strand Lifting Loops
Authors: Chhetri Sandip , Cross Rachel Chicchi
Published: April 2024

An experimental investigation of 28 tests was conduct¬ed to determine the load-carrying capacity of 0.6 in. (15.2 mm) diameter prestressing strand lifting loops. The parameters studied were number of strands in a loop (1, 2, 3, or 4), lifting device (shackle or hook), vertical offset or use of a crushed sleeve, projection of loop from the top of the concrete, and splaying of strand legs. Strand rupture was the primary failure mode, though pullout and side-face blowout became prominent modes in multiple-strand cases. A uniform bond stress of 100 psi (690 kPa) can be used to deter¬mine a safe load. Multipliers of 1.9, 2.8, and 3.3 were determined for double-, triple-, and quadruple-strand loops. Hooks decreased the loop’s capacity by approx¬imately 12% relative to a 2.4 in. (61 mm) diameter pin. A vertical offset of 1 in. (25.4 mm) decreased the loop’s capacity by approximately 42%. Efforts should be made to ensure even loading of the multiple strands within a loop.
Between-session chasing of losses and wins in an online eCasino
Authors: Zhang Ke , Rights Jason D. , Deng Xiaolei , Lesch Tilman , Clark Luke
Published: April 2024

Background and aims

This study characterized chasing behaviour as the time to return to an online gambling website after a losing or a winning visit.

Methods

We analyzed a naturalistic dataset from an eCasino (PlayNow.com, the provincial platform for British Columbia, Canada), comprising 1,909,681 sessions from 15,544 individuals. Analyses distinguished sessions on slot machines, blackjack, roulette, video poker, probability games, or mixed-category sessions.

Results

Overall, gamblers on most games returned more slowly as a function of the prior loss, and more quickly as a function of the prior win. Loss chasing intensities in blackjack, probability, video poker, and mixed sessions did not differ significantly from slot machines, but roulette was associated with shorter intervals to return (b = −0.13, p < 0.001). Similarly, win chasing did not vary across slot machines, blackjack, probability games, and video poker, but roulette (b = −0.08, p < 0.001) and mixed (b = −0.02, p = 0.009) sessions were associated with shorter intervals.

Discussion and conclusions

The average behavioural patterns provide limited evidence for loss chasing but clearly indicate win chasing. Although slot machines are commonly considered a high-risk product, roulette in our analyses was associated with the greatest chasing intensities.
Morphological and structural properties of silver/chlorargyrite nanoparticles prepared using Senecio madagascariensis leaf extract and interaction studies with bovine serum albumin
Authors: Hlapisi Nthabeleng , Songca Sandile P. , Ajibade Peter A.
Published: April 2024

Senecio madagascariensis leaf extract was used to synthesize silver/chlorargyrite nanoparticles. XRD diffraction patterns confirmed the nanocrystalline phase with a face-centered crystal structure of metallic silver. The TEM revealed that the silver and silver chloride nanoparticles were spherical and polydisperse with a decreasing size with respect to the concentration of the silver salt and an average size in the range 13–25 nm. The optical band gaps for Ag/AgCl are 2.71, 2.73, and 2.66 eV for nanoparticles prepared with 20 mM, 50 mM, and 100 mM, respectively. The SEM–EDX confirmed the presence of elemental Cl and Ag. The results show that S. madagascariensis could be used to prepare environmentally friendly bioactive silver nanoparticles. Fluorescence data indicated that static quenching played a role in the formation of the complex between AgNPs and BSA.

Earth’s atmosphere is a mixture of many gases which include pollutants such as SO2, NO2, NO, and O3 that have absorption  in the ultraviolet (UV) wavelength region. Therefore, the development of  broadband UV laser sources that are useful in a differential absorption spectroscopy (DOAS) system for environmental research is necessary. In this research, we present the DOAS system using the Ce:LiCAF laser for determining SO2 gas concentration in the atmosphere. The Ce:LiCAF laser has a full width at half maximum of 2 nm with a wavelength range from 286 to 291 nm and a peak wavelength of 288.5 nm. The results show that the DOAS system accurately determines the gas concentration with a measurement error of 6 %. This result can serve as the basis for developing practical DOAS systems with the ability to monitor a wide range of gasses and survey many other types of pollutants.
Thermal behavior of irradiation-induced-deep level in bulk GaN used for fabricating blue light emitting diodes
Authors: Tran Thien Duc , Le Thi Hai Thanh
Published: April 2024

Bulk GaN was irradiated by 2 MeV electron beam at a fluence of 5 × 1016 cm2 and studied by deep level transient spectroscopy (DLTS). After irradiation, a broad peak, including at least two traps, was detected. The trap D1 (EC – 0.16 eV) observed from a broad peak is induced during the annealing process below 550K and completely annealed out at 550K after ~ 10 hours. The annealing process at 550K also forms a new trap D2 (EC – 0.25 eV). From the isothermal study the activation energy of the trap D2 in the annihilation process is obtained and has a value of 1.3 ± 0.3 eV. The pre-factor of the annihilation process suggested this process to be related to the free-carrier capture by multi-phonon emission. From the thermal behavior, the trap D2 was suggested to be related to gallium vacancy.

Introduction: Different physical, social, affective, and sexual changes take place during adolescence, such as the sexual debut. Objective: To explore the factors associated with the onset of sexual activity in adolescents attending school (12–16 years) in Bucaramanga. Materials and Methods: This analytical cross-sectional study included 440 adolescents from a public school. An instrument developed by Latin American Center for Perinatology - History of Adolescents was applied, and descriptive and bivariate analyses were conducted using a binomial regression model adjusted by age and sex, with sexual activity onset as the outcome and possible associated factors as exposures. Results: The prevalence of the onset of sexual activity was 22.27% (95% CI: 18.56–26.46). Factors associated with greater prevalence of sexual activity onset were having a criminal record and partner PR=3.24, (95%CI: 2.60–4.05) and PR=2.00, (95%CI: 1.42–2.82), respectively. Male gender PR=1.19, (95% CI: 0.84–1.67), using tobacco PR=1.23 (95% CI: 0.73–2.06), alcohol consumption PR=1.23, (95% CI: 0.73–2.06), and other psychoactive substance use PR=1.78, (95% CI: 0.99–3.19) were risk factors; meanwhile, socializing with friends was a protective factor PR=0.27, (95% CI: 0.20–0.36). Discussion: Follow-up by parents and school support decrease the risk of adolescent sexual activity onset. Furthermore, interventions in the family and school settings are important. Conclusion: There are conditions that could promote the beginning of sexual activity in adolescence such as being male, having a partner, having a criminal record, smoking, and consuming alcohol or other substances could promote adolescent sexual activity onset, while socializing with friends was found to be a protective factor.

Існуючі сучасні проблеми виробництва штучного холоду пов’язані з використанням нетрадиційних і відновлювальних джерел енергії та з виконанням світових екологічних вимог. Сонячна енергетика узгоджується з концепцією розподіленого виробництва енергії з отриманням трьох корисних ефектів: електрики, тепла та холоду. Абсорбційні водоаміачні термотрансформатори (АТТ) є елементом енергоперетворювальної системи. В роботі представлено синтез схем і циклів понижувальних АТТ з залученням термодинамічного аналізу «методом циклів». Здійснено поетапний перехід від оборотного циклу-зразка до теоретичного циклу водоаміачного термотрасформатора з інженерними обмеженнями шляхом зміни параметрів циклу: температур гріючого джерела та охолоджуючого середовища, зони дегазації. У аналізі температуру виробництва холоду прийнято постійною, зону дегазації прийнято чинником ефективності циклу. Розглянуто термодинамічну схему та цикл гібридного термотрасформатора – одноступенева абсорбційна машина з механічним бустером (компресором або ежектором). Запропоновано напрямки у роз-витку термотрансформатора у випадку низької температури гріючого джерела або високої температури охолоджуючого середовища. Надано термодинамічні схеми гібридних систем з компресором (ежектором) на стороні високого тиску та на стороні низького тиску з механічним та тепловим приводом бустера. Розглядаючи ежектор як пароструминний компресор, встановлено, що термодинамічні цикли термохімічних компресорів з тепловим приводом бустерів збігаються. Різноманіття схемних рішень гібридних термотрасіорматорів значно більше циклових, тому для абсорбційно-компресорних розглянуто лише циклові рішення. Безліч схем засновано на взаємному розміщенні основного та додаткового контурів. Будь-яке схемне рішення має як позитивні, так і негативні якості. Тільки результати термоекономічного аналізу за конкретних умов експлуатації можуть вказати оптимальне схемне рішення

Published: April 2024

The effectiveness of the supersonic combustor is strongly dependent on the design of the strut fuel injector. This research employs numerical analysis to investigate the combustion and flow features of the supersonic combustor, utilizing Ansys Fluent for solving the unsteady Reynolds-averaged Navier-Stokes equations along with the finite-rate/eddy-dissipation model and shear stress transport k-ω turbulence model. To boost both mixing and combustion performance, a new two-strut concept is introduced into the scramjet combustor. While previous studies have focused mostly on stable 2D two-strut setups, the current investigation aims to fill a gap by exploring an unsteady three-dimensional two-strut configuration. The validation process begins by comparing numerical methods with experimental data obtained from open literature. Following this, a comparative analysis is conducted between the mixing and overall pressure
loss performance of a generic strut and the recently introduced two-strut configuration. The computational findings exhibit a satisfactory alignment with the data collected from experiments. Importantly, the inclusion of the two-strut signifies a notable enhancement in the supersonic combustor's mixing level, surpassing the performance of the original single-strut design. The mixing efficiency plot indicates that two-strut achieves full mixing earlier, covering a distance of 0.182 m, compared to the DLR strut, with a 24% boost in mixing efficiency.

Using high throughput amplicon sequencing to determine the diet of two generalist stink bugs (Hemiptera) in agricultural and urban landscapes. v1
Authors: Berteloot Olivier
Published: April 2024

The use of DNA metabarcoding has become an increasingly popular technique to inferfeeding interactions in herbivores and generalist predators and are especiallyuseful when the organism of interest is polyphagous. Inferring host plantpreference of native and invasive herbivore insects can be helpful inestablishing effective Integrated Pest Management strategies (IPM). Both stinkbugs, Halyomorpha halys, and Pentatoma rufipes, are knownpests that cause severe economic damage in agroecosystems, primarily commercialfruit orchards. In this study, we performed Molecular Gut Content Analysis(MGCA) of these two polyphagous herbivore stink bug species using next-generationamplicon sequencing (NGAS) of the Internal Transcribed Spacer 2 (ITS2) barcoderegion. Additionally, a laboratory experiment with a host switch from a mixeddiet to a monotypic diet with H. halys was conducted to determine thedetectability of the original host plants in a time series up to 3 days afterthe host switch occurred. In our field samples, we detected 55 unique plantgenera across the two stink bug species. The sampling location significantlyimpacts the observed genera in the diet of both stink bug species, while weobserve no significant seasonal differences. Moreover, this study providesadditional support for the efficiency of DNA metabarcoding techniques to infer thedietary composition of polyphagous herbivores, delivering species-levelresolution of hostplant-herbivore interactions. Lastly, our study provide aninitial framework for more extensive DNA metabarcoding studies further tounravel the polyphagous diet of these two pentatomid herbivores.

El presente estudio evalúa los contenidos emocionales del programa de Lengua y Literatura Española ComunicARTE y el impacto que éstos producen en el desarrollo de la competencia socioemocional de alumnos de segundo ciclo de Educación Primaria. Se analizan los contenidos del programa a partir de un modelo teórico de Competencia Socioemocional y se realiza un estudio de 2 años con evaluación pre-postest en 5 grupos experimentales y 2 grupos control (n=170). Del análisis cualitativo del programa se desprende que se trabaja de forma explícita la competencia emocional y sus principales dimensiones. El análisis de regresión lineal indica que el programa ComunicARTE tiene un impacto significativo en el desarrollo de la competencia emocional del alumnado de los grupos experimentales, contrarrestando su punto de partida, inferior a la medida, y especialmente en los niños. Aunque el desarrollo se observa en todas las dimensiones de la competencia emocional, especialmente mejoran la regulación emocional, la autonomía emocional y las competencias de vida y bienestar. El Programa resulta ser un buen material para integrar el desarrollo de la competencia emocional en el horario lectivo a través de la asignatura de Lengua y Literatura.

BACKGROUND: The effect of Helicobacter pylori (HP) on the course of sialadenosis (sialosis) of parotid salivary glands in patients with HP-associated gastrointestinal pathologies remains a relevant issue.
AIM: To improve the effectiveness of diagnosis in patients with parotid salivary gland sialadenosis and acid-dependent diseases associated with HP.
MATERIALS AND METHODS: The study included 40 patients aged 47.03±6.33 years with sialadenosis of parotid salivary glands and HP-associated gastrointestinal diseases diagnosed by immunochromatographic antigenic test using fecal samples and enzyme immunoassay of blood serum for anti-H. pylori IgG before eradication treatment. All patients underwent a comprehensive examination including basic tests (collection of complaints, anamnesis data, external examination and palpation of the regional lymph nodes and salivary glands, oral cavity examination), sialometry, express test (Helicobacter test), polymerase chain reaction diagnostics of parotid salivary gland secretion for HP, and measurement of proinflammatory cytokine levels (interleukin-1β and interleukin-6, and tumor necrosis factor-α in pg/mL). Patients with sialadenosis of the parotid salivary glands depending on HP detection in parotid secretions were divided into groups I (n=7, aged 45.14±8.51 years, negative) and II (n=33, aged 47.42±5.85 years, positive). The control group included 20 practically healthy people aged 45.40±6.54 years.
RESULTS: In group I (HP not detected in the parotid secretion), a reactive–dystrophic process of parotid salivary glands was found, which resulted from an increase in the concentration of proinflammatory interleukins. In group II (HP detected in the parotid saliva), severe sialosis of the parotid salivary glands was observed, which was caused by local inflammation and changes in cytokine status.
CONCLUSION: The comprehensive plan of the examination of people with parotid salivary gland sialadenosis and HP-associated gastrointestinal tract diseases should also include Helicobacter test, and the levels of proinflammatory cytokines in parotid secretions must be measured.
