Objectives

The present study aimed to evaluate the performance of QuantusFLM® software, which performs quantitative ultrasound analysis of fetal lung texture, in predicting lung maturity in fetuses of diabetic mothers.

Methods

The patients included in this study were between 34 and 38 weeks and 6 days gestation and were divided into two groups: (1) patients with diabetes on medication and (2) control. The ultrasound images were performed up to 48 h prior to delivery and analyzed using QuantusFLM® software, which classified each fetus as high or low risk for neonatal respiratory morbidity based on lung maturity or immaturity.

Results

A total of 111 patients were included in the study, being 55 in diabetes and 56 in control group. The pregnant women with diabetes had significantly higher body mass index (27.8 kg/m2 vs. 25.9 kg/m2, respectively, p=0.02), increased birth weight (3,135 g vs. 2,887 g, respectively, p=0.002), and a higher rate of labor induction (63.6 vs. 30.4 %, respectively, p<0.001) compared to the control group. QuantusFLM® software was able to predict lung maturity in diabetes group with 96.4 % accuracy, 96.4 % sensitivity and 100 % positive predictive value. Considering the total number of patients, the software demonstrated accuracy, sensitivity, specificity, positive predictive value and negative predictive value of 95.5 , 97.2, 33.3, 98.1 and 25 %, respectively.

Conclusions

QuantusFLM® was an accurate method for predicting lung maturity in normal and DM singleton pregnancies and has the potential to aid in deciding the timing of delivery for pregnant women with DM.

Published: April 2023

Sustainable peatland management needs collaboration among many actors. This study portrayed the role of actors in managing peatland in Kubu Raya Regency, West Kalimantan, based on their interests and influence factors. We employ the purposive sampling method to select 13 actors to represent their institutions to assess their organization’s level of interest and influence in peatland management. The results indicated four existing groups categorized as key players, context setter, subject, and crowd. The key player group has the primary role in program planning and implementation of the Forest Management Unit of Kubu Raya, Wetland Ecosystem Management Unit, Regional Development Planning Agency, and Agriculture Service of Kubu Raya Regency. The subject group supports peatland management programs in the implementation and supervision role, which consists of forest concessionaire (PT Ekosistem Khatulistiwa Lestari) and communities. The context setter group has roles in regional planning, regional supervision, and monitoring of fire hazards, including Production Forest Management Institute in Pontianak, Fire Brigade, and Regional Forest Area Designation Agency III in Pontianak. The last stakeholder is the extension worker categorized in the crowd group, which empowers and assists the community in managing peatland. Avoiding conflicts of interest and promoting collaborative actions are essential factors needed to ensure sustainable peatland management.
Reaction dynamics of molecules in highly electronically excited states attained by multiphoton and multiple excitation methods
Authors: Miyasaka Hiroshi , Ito Syoji , Sotome Hikaru
Published: April 2023

Multiphoton absorption and multiple excitation can lead to the formation of highly electronically excited states of molecules. We have been applying these excitation methods to explore specific photochemical reactions, which are rather difficult to attain by normal one-photon absorption processes. In the present review, we will introduce several examples of these photochemical responses specific to highly excited state in the condensed phase, such as two-photon-gated cycloreversion, one-color control of both reactions in photochromic systems and rapid capture of an electron ejected from the higher excited state leading to rapid generation of charge-separated states at the high energy level with a lifetime much longer than microseconds.

The cost of the coolant and its disposal cost are significant issues in metal machining processes. In biocompatible magnesium alloy-based medical implants and instrument manufacturing, the cost hikes are owing to the use of unconventional machining processes and computerised numerical control machines. This research aims to improve machinability performance and optimize process parameters for biocompatible magnesium implant manufacturing for biomedical applications using eco-friendly nanofluid of MoS2 nanoparticles suspended in waste coconut oil. The nanofluid was prepared from the multiple times used waste coconut oil (waste) and was mixed with MoS2 nanoparticles. The orthogonal array L16, Taguchi analysis, and analysis of variance were employed in experimental design and statistical optimization. The machinability performance was determined by measuring and comparing the responses like cutting force, feed force, surface roughness, cutting zone temperature, and tool wear. They were compared with machining using a nanofluid and conventional commercial coolant. The results reveal that the proposed method of machining improved machinability performance appreciably; therefore, the observations of the proposed method were used and the process parameters were optimized. Mathematical models were developed for the prediction of process parameters. The proposed method exhibited the average reduction of the cutting force by 68.23167 N, feed force requirements by 34.180 N, the cutting zone temperature by 60.435°C, the surface roughness by 0.118908 µm, and the tool wear by 039938 mg·h−1.
LEITURA E ESCRITA DO MUNDO
Authors: Lusa Diana
Published: April 2023

Tendo como proposta embasar-se em referências locais para as análises, de acordo com um pensamento decolonial, esta escrita objetiva refletir sobre a relação da mulher com a leitura e com a escrita. Com um olhar especial ao primeiro livro de Carolina Maria de Jesus, são aprofundadas e discutidas as temáticas: mulheres e escritas de si, escrevivência, mulher negra, leitura de mundo, sendo a discussão transversalizada pelos conceitos gênero, classe e raça. O problema central deste estudo é perceber como a leitura e a escrita emergem no livro Quarto de Despejo, de Carolina Maria de Jesus, mulher, negra, pobre, em um processo de escrevivência. A obra é analisada à luz das teorias de Conceição Evaristo; Paulo Freire; Joan Scott; Guacira Lopes Louro; Constância Lima Duarte e Isabella Rosado Nunes. Perecemos que a fome é o fio que perpassa os escritos de Carolina; sua escrita mostra sua leitura de mundo em se perceber mulher, negra, rejeitada, esquecida juntamente com seus filhos; em entender condições sociais, políticas e injustiças a que está submetida. Com a análise podemos dizer que o livro analisado permite ter uma noção da barbárie social em determinada favela do Brasil na década de 1950. A obra nos apresenta a capacidade da autora de ler seu mundo e agir nele dentro do que lhe é possível, também de questionar o que está posto, as políticas, os políticos, a falta de perspectiva. De trazer seus sonhos: morar em uma casa melhor, limpa, ter comida, ver seus filhos educados e na escola.
Citadels of Crisis
Authors: Obadare Ebenezer
Published: April 2023

Once highly regarded as centers of excellence, Nigerian universities now uniformly occupy the basement of most global university rankings. At the same time, the nation’s academia is all but shorn of the social prestige that previously attached to it. This essay argues that neither the specific degradation of the professoriate, nor the broader crisis of higher education, can be understood without attention to the crisis of the postcolonial Nigerian state. Accordingly, restorative strategies must take into account the historicity of the crisis, and its insertion into a whirlpool of national, regional, and global forces.
“Listen and Be Amazed!”: Odeon, Künneke, and the First Recordings of Complete Symphonies
Authors: Hepokoski James
Published: April 2023

Between 1911 and 1913, Odeon records, in Berlin, produced and made available for sale five complete, four-movement symphonies, the first complete symphonies ever recorded. They were Beethoven’s Fifth and Sixth Symphonies (August and November–December 1911), and then Haydn’s Symphony no. 94 (“Surprise”) and Mozart’s Symphonies nos. 40 and 39 (in that order, March and April 1913). Each was performed by members of the Odeon company’s orchestra, billed as the “Großes Odeon-Streich-Orchester.” While no conductor is identified on the labels, it was surely Eduard Künneke, Odeon’s house conductor at that time. (Arthur Nikisch’s Beethoven’s Fifth with the Berlin Philharmonic would follow, from Grammophon records, in November 1913.) Odeon’s decisions to record these five symphonies took place within two larger corporate contexts, 1907–13: first, that of what was becoming increasingly possible within the enabling yet constraining affordances of the era’s music-recording industry; second, that of how those affordances were giving rise to the more innovative plans and economic gambles of recording extended classical works—longer stretches of operetta and opera, high-prestige orchestral music, and, eventually, symphonies. Much of this history can be traced in reports, reviews, and advertisements in the contemporaneous German trade journal the Phonographische Zeitschrift. The whole is framed here within the contexts of recent media theory and varying views of the impact of sound recordings on twentieth- and twenty-first-century listening practices. As Antoine Hennion put it, “The disc has been powerful enough to introduce modern listeners to musical repertoires conceived with a different relationship in mind.”
Fractured Tablets
Authors: Balberg Mira
Published: April 2023

This book examines the significant role that memory failures play in early rabbinic literature. The rabbis who shaped Judaism in late antiquity envisioned the commitment to the Torah and its commandments as governing every aspect of a person’s life. Their vision of a Jewish subject who must keep constant mental track of multiple obligations and teachings led them to be preoccupied with forgetting: forgetting tasks, forgetting facts, forgetting texts, and—most broadly—forgetting the Torah altogether. In Fractured Tablets, Mira Balberg examines the ways in which the early rabbis approached and delineated the possibility of forgetfulness in practice and study and the solutions and responses they conjured for forgetfulness, along with the ways in which they used human fallibility to bolster their vision of Jewish observance and their own roles as religious experts. In the process, Balberg shows that the rabbis’ intense preoccupation with the prospect of forgetfulness was a meaningful ideological choice, with profound implications for our understanding of Judaism in late antiquity.
Is posterior knee arthroscopy using posterior portals necessary for orthopedic surgeons? The latest evidence on applications and techniques
Authors: Keyhani Sohrab , Movahedinia Mohammad , Sherafat Vaziri Arash , Soleymanha Mehran , Vosoughi Fardis , Tahami Mohammad , LaPrade Robert F
Published: April 2023

Various uses of posterior knee arthroscopy have been shown, including all-inside repair of posterior meniscal lesions, posterior cruciate ligament (PCL) reconstruction or PCL avulsion fixation, extensile posterior knee synovectomy for pigmented villonodular synovitis or synovial chondromatosis, posterior capsular release in the setting of knee flexion contractures, and loose bodies removal.

Posterior arthroscopy provides direct access to the posterior meniscal borders for adequate abrasion and fibrous tissue removal. This direct view of the knee posterior structures enables the surgeon to create a stronger biomechanical repair using vertical mattress sutures.

During PCL reconstruction, posterior arthroscopy gives the surgeon proper double access to the tibial insertion site, which can result in less acute curve angles and the creation of a more anatomic tibial tunnel. Moreover, it gives the best opportunity to preserve the PCL remnant. Arthroscopic PCL avulsion fixation is more time-consuming with a larger cost burden compared to open approaches, but in the case of other concomitant intra-articular injuries, it may lead to a better chance of a return to pre-injury activities.

The high learning curve and overcaution of neuromuscular injury have discouraged surgeons from practicing posterior knee arthroscopy using posterior portals. Evidence for using posterior portals by experienced surgeons suggests fewer complications.

The evidence suggests toward learning posterior knee arthroscopy, and this technique must be part of the education about arthroscopy. In today's professional sports world, where the quick and complete return of athletes to their professional activities is irreplaceable, the use of posterior knee arthroscopy is necessary.
Metagenomic next-generation sequencing in osteoarticular infections with a focus on pediatrics: current concepts and clinical applications
Authors: Gupton Marco , Burns Jessica
Published: April 2023

Osteoarticular infections (OAI) are a significant cause of morbidity and mortality. Cultures and serology are some of the gold standards for identifying infection but are often unable to provide a timely diagnosis or a diagnosis at all.

Genetic testing offers capabilities that other modalities lack. Polymerase chain reaction has multiple versions with various costs and turnaround times. This technology has become implemented in multiple pediatric center OAI diagnostic protocols. There is sufficient literature documenting effectiveness in certain clinical situations, especially with fastidious organism diagnosis, but significant limitation still exists.

Metagenomic next-generation sequencing is an unbiased or hypothesis-free modality with the capability to detect the genetic material of bacteria, viruses, parasites, fungi, and humans from a single sample.

Potential benefits include pathogen identification unaffected by antimicrobial administration, detection of fastidious organisms more quickly, delineation of pathogens in polymicrobial infections, antimicrobial susceptibility, and avoidance of invasive procedures.

It is a resource-intensive modality with little standardization of the complex processes. Appropriate use and definitive clinical impact have yet to be determined.
Preantral follicle numbers and size in heifers carrying Trio, a bovine high fecundity allele

Published: April 2023

In brief

The bovine high fecundity allele, Trio, results in the occurrence of multiple ovulations and is characterized by antral follicles that develop slower and acquire ovulatory capacity at smaller sizes. This study provides novel information on the effect of the Trio allele on early folliculogenesis.

The bovine high fecundity allele, Trio, causes overexpression in granulosa cells (GCs) of SMAD6, an inhibitor of BMP15-activated SMAD signalling. Furthermore, the Trio allele results in antral follicles that develop slower, acquire ovulatory capacity at smaller sizes, and have three-fold greater ovulation rate compared to half-sib non-carriers. The present study was designed to determine preantral follicle numbers and size in Trio carrier and non-carrier cattle testing the hypothesis that inhibition of SMAD signalling would alter preantral follicle activation and/or growth. Ovarian tissues from Trio carrier (n = 12) and non-carrier (n = 12) heifers were obtained by laparotomy after follicle wave synchronization. Follicle numbers and dimensions were determined for each stage of development (primordial, transitional, primary, and secondary) from paraffin-embedded sections. There were no differences in the number of primordial, transitional, or secondary follicles or in antral follicle count, circulating AMH, or ovarian volume between carriers and non-carriers. Trio carriers had ~2.5-fold greater (P < 0.01) number of primary follicles than non-carriers, and transitional and primary follicles were larger (~1.2-fold; P < 0.1) in Trio carriers. Oocyte volume of primordial and transitional follicles was not different between genotypes; however, oocytes were larger (P < 0.05) in primary (~1.3-fold) and secondary (~1.8-fold) follicles for Trio carriers. Granulosa cell numbers were not different (P > 0.3) between carriers and non-carriers, irrespective of the stage of development. These results suggest that, after primordial follicle activation, follicles in Trio carrier cattle have slower progression through the primary stage, hence the larger oocyte and greater number of primary follicles.

Authors: Muller Olga
Published: April 2023

Universities have created conditions for organizing an integral system that provides high-quality professional training and social integration of people with limited health opportunities. However, the development of inclusive vocational education requires a systematic solution to a number of problems, which include the problem of the existing deficit in universities of innovative educational programs and forms of education focused on inclusive vocational education. The purpose of the study is to develop the structure of a model of an individual educational trajectory for a student with disabilities and to test its effectiveness experimentally. An individual learning path allows each student, including those with disabilities, to develop a creative individuality, personal and professional qualities. Methods used in the study: generalization, analysis and synthesis of information, comparison, pedagogical experiment. For the experiment, a comparison was made of the performance of two groups of students, divided by the criterion of the presence or absence of health limitations. The author has developed a model of an individual trajectory of a student with health limitations, which is based on modules that are professionally significant actions (learning elements). The theoretical and practical significance of the work is presented by the developed model of an individual educational trajectory for teaching students using modular technology, which can be applied in the practice of teaching universities in order to improve the quality of training students with disabilities.

Analysis of the fatty acid composition of total cellular lipids is important chemotaxonomic characteristic that is used to identify microorganisms, in particular actinobacteria, with the help of fatty acid spectra libraries. Actinobacteria are well known as producers of secondary metabolites, which are of pharmacological and commercial interest. A significant number of actinomycetes is associated with various marine benthic communities. The aim of this study was determination of the fatty acid composition and preliminary identification of actinobacteria isolated from mussels Mytilus galloprovincialis of the Black Sea Odesa Bay. Actinobacteria of 12 isolated strains were grown in a liquid medium at 28° C for 72 h. Methyl esters of fatty acids were determined on a gas chromatograph Agilent. The MIDI Sherlock microorganisms identification system was used to identify the studied strains. It was found that the fatty acids methyl esters profiles of studied actinobacteria strains were characterized by the predominance of 12-17 saturated branched-chain fatty acids with high content of 12-methyltridecanoic, 12-methyltetradecanoic, 14-methylpentadecanoic and 14-methylhexadecanoic fatty acids. All 12 actinobacteria strains isolated from mussels (Mytilus galloprovincialis) of Odesa Bay were identified as members of the Streptomyces genus.

Since the emergence of the newly identified Coronavirus SARS-COV-2, no targeted therapeutic agents for COVID-19 treatment are available, and effective treatment options remain very limited. Successful crystallization of the SARS-CoV-2 main protease (Mpro, PDB-ID 6LU7) made possible the research on finding its potential inhibitors for the prevention of virus replication. To conduct molecular docking, we selected ten representatives of the Cathepsin inhibitors family as possible ligands with a high potential of binding the active site of SARS-CoV-2 main protease as a potential target. The results of molecular docking studies revealed that Ligand1 and Ligand2, with vina scores -8.8 and -8.7 kcal/mol for Mpro, respectively, were the most effective in binding. In silico prediction of physicochemical and toxicological behavior of assessed ligands approved the possibility of their use in clinical essays against SARS-COVID-19.

The article discusses the infection of wetland birds in Uzbekistan with the trematodes Schistosomatidae Stiles et Hassall, 1898. The research covered 282 individuals from the main groups of birds represented by the orders Pelecaniformes, Ciconiformes, Anseriformes, Gruiformes, Podicipediformes and Charadriiformes. The Schistosomatidae fauna of Uzbekistan includes 13 species: Bilharziella polonica (Kowalewsky, 1895), Trichobilharzia ocellata (La Valette, 1854), T. filiformis (Szidat, 1938), T. kowalewskii (Ejsmont, 1929), T. tatianae (Spasskaja, 1953), Macrobilharzia macrobilharzia Trawassos, 1923, Ornithobilharzia canaliculata (Rudolphi, 1819), O. baeri Fain, 1955, Dendritobilharzia pulverulenta (Braun, 1901), D. loossi Skrjabin, 1924, D. anatinarum Cheatum, 1941, Gigantobilharzia acotylea Odhner, 1910 and Gigantobilharziella monocotylea (Szidat, 1930). Predominant are representatives of the genera Trichobilharzia and Dendritobilharzia. The species composition of Schistosomatidae is most diverse in birds from the lower reaches of the Amu Darya, where a high rate of infection with larvae of some of these trematodes was also recorded in aquatic molluscs. 11 species of molluscs were registered in the studied regions: Galba truncatula (Muller, 1774), Stagnicola corvus (Gmelin, 1791), Radix auricularia (Linnaeus, 1758), Lymnaea stagnalis (Linnaeus, 1758), Physa fontinalis (Linnaeus, 1758), Physella acuta (Draparnaud, 1805), Planorbis planorbis (Linnaeus, 1758), P. tangitarensis Germain, 1918, Anisus spirorbis (Linnaeus, 1758), Gyraulus albus (Muller, 1774), Melanoides kainarensis Starobogatov et Izzatullaev, 1980, from the families Lymnaeidae (4 species), Planorbidae (4 species), Physidae (2 species) and Thiaridae (1 species). They are identified as intermediate hosts of Schistosomatidae and were infected with 7 species of flukes. The total rate of infection with larval stages of Schistosomatidae in molluscs was about 2.0%. The highest infection rate was observed in Melanoides kainarensis – 5.3%. Morpho-biological indicators for mature forms of B. polonica from different bird species (Anas platyrhynchos and Oxyura leucocephala) were confirmed by molecular genetic studies. The study identified foci of birds’ infection with Schistosomatidae and the occurrence of human cercarial dermatitis.

Large carnivores play an important role as indicators of the state of the natural ecosystems. The analysis of the number and distribution of large carnivores (brown bear – Ursos arctos, Eurasian lynx – Lynx lynx and grey wolf – Canis lupus) was established in the Ukrainian Carpathians and Ukrainian Polissya. Annual data on the number of large carnivores on the territories of hunting units and nature conservation areas from 2009 to 2019 was summarized. To analyze the number and distribution of large carnivores in the Ukrainian Carpathians, data from 4 regions were taken into account, namely Lviv, Zakarpattia, Ivano-Frankivsk and Chernivtsi regions. To analyze the number and distribution of large carnivores in Ukrainian Polissya, data from 6 regions were taken into account – Volyn, Rivne, Zhytomyr, Kyiv, Chernihiv and Sumy regions. According to official data obtained from hunting units and nature conservation areas in 2019, there were 375 bears, 435 lynxes and 563 wolves in the Ukrainian Carpathians; and 4 bears, 128 lynxes and 609 wolves in Ukrainian Polissya. Based on the collected data, the maps of the distribution of large carnivores in the Ukrainian Carpathians and Ukrainian Polissya were created in the format of a grid of squares of 10 by 10 km (cell size 100 km²), namely – density maps of populations of large carnivores, as well as maps of forest habitats of large carnivores. The obtained results provided a better understanding of the dynamics of large carnivores over the last decade in terms of regions, as well as the density of populations of large carnivores in certain areas and their distribution areas in the Ukrainian Carpathians and Ukrainian Polissya. However, the summary results of the number of individuals obtained based on official reports of hunting units and nature conservation areas are overestimated due to the problem of "double" accounting of animals by users of adjacent lands (hunting units, nature conservation areas). Therefore, it is important to establish synchronization of accounting between users of adjacent lands (nature protection areas, forestries, etc.), to use unified research methods, and to exchange monitoring data and information between institutions of different state subordination. Such scientifically based data are the basis for the development and implementation of measures for the conservation and management of large carnivore populations at the regional, national and international levels.

Mining activities radically change natural ecosystems, the recovery of which is not possible without the restoration of native or transformed communities of autotrophic and heterotrophic organisms. In order to analyze the success of biodiversity restoration using unified methods, an inventory of higher plant flora and avifauna species in the technogenic territories of the Poltava Mining and Processing Plant was carried out. The dominant species identified in mining dumps, tailings, bypass and drainage canals, urban wastewater treatment and bioengineering facilities and on the PMP territory have been studied in detail. The studies were carried out in the spring-summer period of 2021–2022. The avifauna includes 140 species belonging to 18 orders and 45 families (Passeriformes predominate – 62.0%). 103 species nest on the PMP territory, 32 nomadic and 5 transient species are also registered. The nesting avifauna is dominated by representatives of both native nemoral (16.0%, n = 103) and forest-steppe (13.0%) and tropical (14.0%) avifauna. A significant number of birds belong to limnophiles, which prevail in the territories of the urban wastewater treatment plant (66.7%, n = 30) and tailings (62.5%, n = 24). They are also common in the bypass and drainage canals, where hydro- and hygrophilous phytocenoses have formed, similar to floodplain and real meadows as part of adjacent wetland ecosystems. Among the surrounding natural biogeocenoses, there are no steppe ones with their inherent unique floristic composition, which explains the small number of stepants in the studied flora and campophiles in the avifauna. In recovery successions, general patterns were revealed: biogeocenoses surrounding the technogenic territories of the PMP are the main source of producer diasporas and a variety of consumers, which are so necessary for the restoration of degraded landscapes. Phanerophytes from the genera Populus, Pinus, Fraxinus, Ulmus, Morus, Juglans, etc. are determinants in the sylvacenoses formed on the dumps and territories of the plant. Therefore, dendrophiles characteristic of neighbouring pine and floodplain forests, as well as garden phytocenoses in the private sector territory, dominate in the ornithocomplexes. Nationally rare avifauna includes 5 species, two of which nest. Among the identified bird species, the following nesting species are listed in the Red Book of Ukraine: Columba oenas, Himantopus himantopus, as well as transient and nomadic species: Hieraaetus pennatus, Haliaeetus allbicilla, Milvus migrans. The success of the natural formation of plant communities, the rich ornithological complex with the participation of rare species, and the location of the PMP territory within the migration routes indicate the expediency of further research into the possibilities of their inclusion in the nature reserve fund with the status of “territory of renaturalization”.

Published: April 2023

The Mediterranean Sea is one of the busiest areas worldwide in terms of maritime activity and faces considerable anthropogenic disturbances, such as pollution by hydrocarbons and heavy metals. This study evaluated the environmental status of three sites on the Algerian coast using the annelid polychaete Perinereis cultrifera as a biomonitoring sentinel species. It included different reproductive parameters such as oocyte diameter, frequency distributions, sexual maturity index, biochemical quantitative parameters represented by the vitellogenins and vitellins, and a histological study of the coelome during the reproductive period. The results showed that the females collected from El-Kala (healthy site) have the highest diameter 304.1 ± 24.3 μm during April but the values were increased in Annaba 290.0 ± 21.0 μm and Skikda 245.3 ± 26.7 μm. Significant differences were observed between worms from the three study sites during the three months of the study. Moreover, the size-frequency indicated that a relatively high proportion of females containing mature oocytes was found in April in females collected at El-Kala 52.4%, 46.4% in females collected at Annaba and 36.7% in females collected at Skikda. In addition, regarding the sexual maturity index, the highest values were recorded in April (3.8, 2.9, and 1.9) at the El-Kala, Annaba, and Skikda study sites. However, the biochemical analysis demontrated that the highest mean concentration of vitellogenin was in females of El-Kala (5.3 ± 0.3 µg/mg of coelomic fluid) in April, and the lowest mean concentration was measured in females of Skikda (1.5 ± 0.2 µg/mg of coelomic fluid). Therefore, the highest mean concentration of vitellin was measured in females of El-Kala (4.4 ± 0.2 µg/mg of oocytes) in April, while the lowest mean concentration of vitellin was measured in females of Skikda (1.02 ± 0.2 µg/mg of oocytes) in May. Significant differences were observed between worms from the three sites during the three months of the study. Furthermore, histological observations revealed that oogenesis was asynchronous, with oocytes at different stages of vitellogenesis simultaneously present. The structure of the oocytes of females collected at El-Kala showed intense vitellogenic activity due to the presence of very dense yolk cells. In contrast, the oocytes of the females collected from the two polluted sites (Annaba and Skikda) were small, vitellogenesis presented low intensity, and yolk cells were less frequent at the periphery and less uniform at the cytoplasmic mass; the nucleus was smaller, indicating a slower vitellogenic activity. These observations confirm the previously obtained results.

This paper describes a numerical investigation on the seismic design and behavior of a novel reinforced-concrete buckling-restrained brace component for use in precast concrete lateral-load-resisting frames. The design procedure aimed to develop a brace with ductile behavior under reversed cyclic loading. Nonlinear finite element analyses were conducted to investigate the following potential undesirable failure modes of the brace: global buckling of the brace, closure of the end gaps, and local translational buckling of the energy-dissipation bars. The results indicated that failure through global buckling is unlikely for practical brace designs. Closure of the end gaps can be prevented by designing a wide-enough gap at each end of the brace, but design must also ensure that local buckling of the energy-dissipation bars does not occur over their unsupported length across the end gaps. An axially decoupled steel shear dowel can be used to permit a wider end gap without triggering translational buckling of the energy-dissipation bars. Braces that are designed to prevent undesirable failure modes can provide stable behavior up to ductile low-cycle fatigue fracture of the energy-dissipation bars.
Investigating UHPC in deck bulb-tee girder connections, part 1: Analytical investigation
Authors: Haroon Abdullah , Hamid Waleed , Steinberg Eric , Walsh Kenneth , Miller Richard , Shahrooz Bahram
Published: April 2023

Precast concrete deck bulb-tee girder systems offer an excellent choice for prestressed concrete bridges with spans of 100 ft (30.48 m) or more. These girders are placed side by side in the field and connected using longitudinal joints. The wide top flange of the girders acts as a deck, eliminating the need for a cast-in-place concrete deck and providing a solution for accelerated bridge construction. However, the longitudinal joints between the girders often crack under service loads, allowing for water and deicing chemicals to enter the system and cause corrosion. An analytical study with ultra-high-performance concrete (UHPC) longitudinal joints was performed to investigate the joint performance when subjected to thermal and live loads. A continuity diaphragm with UHPC in the top flange was also investigated for negative moment over pier. Results of the investigation suggest that the use of UHPC can improve the performance of the connections. The high bond strength of the UHPC reduces the connection length and allows for simpler reinforcement details.

Háttér és célkitűzések

A diszpozicionális perfekcionizmus többdimenziós jelenség, mely a személy önmagával szemben állított magas sztenderdjei (perfekcionista törekvések) mellett irreális elvárásokat (perfekcionista aggodalmak) is magában foglalhat. Azt, hogy a személyiségműködésben a perfekcionizmus egészséges vagy maladaptív, önkritikus vonulata a meghatározó, a két perfekcionizmuskomponens aránya határozza meg. Utóbbit különböző pszichopatológiai jelenségek rizikó- és fenntartó faktoraként tartják számon. Kutatásunk célja nem klinikai kamaszpopulációban a multidimenzionális perfekcionizmus különböző mentális egészségmutatókkal (pl. pszichés tünetek, nem szuicidális önsértés) való összefüggéseinek feltárása volt.

Módszer

Vizsgálatunkban 1015 középiskolás (66,1% lány; átlagéletkor 16,81 év; szórás = 1,42) vett részt. A perfekcionizmus komponenseit a Majdnem Tökéletes Skála rövid változatával, az önsértő viselkedést az Állítások az Önsértés Kapcsán Kérdőívvel mértük fel. A pszichés tüneteket a Képességek és Nehézségek Kérdőívvel, míg a mentális jóllétet a Serdülő Mentális Egészség Kontinuum Skála rövid változatával térképeztük fel.

Eredmények

Az önkritikus perfekcionista csoportba sorolható tanulók jelzik a legrosszabb mentális állapotot, körükben a legmagasabb – közel 50% – az aktuális önsértők aránya. Többszörös lineáris és multinomiális regressziós modelleken alapulva rámutattunk, hogy az önkritikus perfekcionizmus jelenléte növeli, míg az adaptív perfekcionista hozzáállás csökkenti mind a mentális betegség tünetszámot, mind az egy hónapon belüli önsértés esélyét. A látens klaszterezéssel azonosított önsértő csoportok közül a Súlyos önsértők csoportjában a legmarkánsabb az önkritikus perfekcionista hozzáállás és a legalacsonyabb a szubjektív jóllét.

Következtetések

Hazai középiskolás mintában is megerősítést nyert, hogy a perfekcionizmus önkritikus komponense rizikófaktorként határozható meg a rosszabb lelki egészségmutatók, kiemelten a nem szuicidális önsértés tekintetében. Az összefüggések alapján a mentális egészség szűrésében és fejlesztésében iskolai közegben is megfontolandó a tanulók perfekcionizmusjellemzőinek azonosítása.

As part of the PADAPT project, the authors compiled the invasion biological database of the alien vascular flora of Hungary, which contains the nativeness, residence time, introduc- tion mode and invasion status of 878 alien or cryptogenic taxa. In the absence of adequate evidence, the classification of some species was only possible into uncertain, transitional cat- egories. The definitions of most categories are compatible with several international termi- nologies, but are primarily based on Central European traditions. Of the 560 taxa that have already been naturalised in Hungary, 85 are invasive, and 22 of them are transformer alien vascular plants. Only 5 of these transformers are included in the European list of Invasive Alien Species of Union concern (Ailanthus altissima, Asclepias syriaca, Elodea nuttallii, Heracleum mantegazzianum and H. sosnowskyi), which require uniform preventive interventions and treatments throughout the continent, while the rest of transformers in Hungary (e.g., Robinia pseudoacacia, Fallopia × bohemica and Solidago gigantea) draw attention to the unique, local and/ or regional invasion biological situation of the Pannonian Basin and Central Europe.

Differentiated instruction in the EFL classroom: An interview study on Hungarian primary and secondary school EFL teachers' views and self-reported practices
Authors: Kótay-Nagy Annamária
Published: April 2023

In recent decades, there have been growing expectations for language teachers to use differentiated instruction (DI) in their classrooms to address the diverse needs of their students. Currently, however, relatively little is known about how teachers of English as a foreign language (EFL) working in Hungarian public education view the concept of DI and implement it in practice. The present study sought to explore this question by interviewing eight Hungarian primary and secondary school EFL teachers on their views and practices of DI. More specifically, the study strove to explore the participants' understanding of and attitude towards DI as well as the differentiation strategies they report to use and the challenges and enablers they perceive when implementing DI. The data were subjected to template analysis. Results suggest that teachers have a solid understanding of the goals of DI and show a primarily positive attitude towards the approach but are less conscious about the strategies available to them and tend to differentiate mostly intuitively. They perceive challenges both in planning and delivering differentiated lessons, such as coping with increased preparation time and having to multitask in class. Exchanging good practices in formal and informal training sessions, cooperating with colleagues and parents, and having rearrangeable furniture and digital tools in the classrooms emerged as enablers of DI. Implications point toward the need for professional development opportunities that help teachers conceptualize their intuitive approaches and extend their repertoire of DI strategies. Researching how technology may enhance DI practices also appears to be warranted.
Numerical simulation of replacement method to improve unsaturated expansive soil
Authors: Alnmr Ammar , Ray Richard
Published: April 2023

In this paper, a parametric study is done with various removal and replacement materials to study the effectiveness of the removal and replacement method on the wetting depth in the expansive soil and the amount of differential heave caused by climate conditions and common irrigation scenarios for the southern region of Syria. Soil suction changes and associated soil deformations are analyzed using finite element codes, VADOSE/W and SIGMA/W. The paper concludes that the optimum thickness for replacement with high permeability soil should be at least 1 m. In addition, it concludes that replacing soil with a permeability coefficient lower than the permeability coefficient of the site soil contributes to a 56% and 79% reduction in total and differential heave, respectively.
Ser racional y uso de razón. Una distinción filosófica (¿inadvertida?) en Francisco de Vitoria
Authors: Gutiérrez-Xivillé Ana-Carolina
Published: April 2023

El presente trabajo es un intento por mostrar que la distinción filosófica entre “ser racional” y “uso de razón” subyace a la posición de Francisco de Vitoria y ofrece el fundamento de legitimidad de su desarrollo político-jurídico. El examen filológico de los textos de las Relectiones y el análisis filosófico-conceptual contextualizado han permitido reconstruir argumentos antropológico-filosóficos, epistemológicos y éticos y explicitar, así, un concepto universal de ser humano que, a su vez, se ha revelado como fundamento de un concepto universal de derecho que concierne a todo ser humano, gracias al cual la propuesta vitoriana alcanzaría aceptación y repercusión global.
