Authors: Shao Guangzhao , Zhi Yao , Fan Zhongqi , Qiu Wei , Lv Guoyue
Published: July 2023

Background

Lung metastasis (LM) is a common occurrence in patients with hepatocellular carcinoma (HCC), and it is associated with a poorer prognosis compared to HCC patients without LM. This study aimed to identify predictors and prognostic factors for LM in HCC patients as well as develop diagnostic and prognostic nomograms specifically tailored for LM in HCC patients.

Methods

A retrospective analysis was conducted on HCC patients from the Surveillance, Epidemiology, and End Results (SEER) database, covering the period from 2010 to 2015. The study employed multivariate logistic regression analysis to identify risk factors associated with LM in HCC patients. Additionally, multivariate Cox proportional hazards regression analysis was utilized to investigate prognostic factors for HCC patients with LM. Subsequently, two nomograms were developed to predict the risk and prognosis of LM in HCC patients. The performance of the nomograms was evaluated through calibration curves, receiver operating characteristic (ROC) curves, and decision curve analysis (DCA).

Result

This retrospective study included a total of 5,934 patients diagnosed with HCC, out of which 174 patients were diagnosed with LM. Through multivariate logistic regression analysis, several independent risk factors for LM in HCC patients were identified, including tumor grade, tumor size, American Joint Committee for Cancer (AJCC) T stage, and AJCC N stage. Furthermore, multivariate Cox analysis revealed that tumor grade, delayed treatment, surgery, and radiation were independent prognostic factors for HCC patients with LM. To assess the predictive power of the developed nomograms, calibration curves, receiver operating characteristic (ROC) analysis, and decision curve analysis (DCA) were employed. The findings demonstrated that the nomograms exhibited satisfactory performance in both the training and validation sets. Additionally, the prognostic nomogram effectively stratified HCC patients with LM into low- and high-risk groups for mortality.

Conclusion

These two nomograms optimally predicted the risk and prognosis of LM in HCC patients. Both nomograms have satisfactory performance. This would help clinicians to make accurate clinical decisions.

Objective

The aim of this study is to investigate the psychometric characteristics of outpatients diagnosed with somatic symptom disorder (SSD) in biomedical, Traditional Chinese Medicine (TCM) and psychosomatic settings.

Materials and methods

A total of 697 participants who completed SCID-5 and questionnaires were presented in our former study, as 3 of them had missed questionnaire data, a total of 694 participants are presented in this study. A secondary analysis of the psychometric characteristics of Somatic Symptom Disorder–B Criteria Scale (SSD-12), Somatic Symptom Severity Scale of the Patient-Health Questionnaire (PHQ-15), Patient Health Questionnaire-9 (PHQ-9) and General Anxiety Disorder-7 (GAD-7) is done to compare differences among outpatients from the three settings of medical specialties.

Results

Based on the DSM-5 criteria, 90 out of 224 (40.2%) participants enrolled in biomedical departments (represented by neurology and gastroenterology departments), 44/231 (19.0%) in TCM departments, and 101/239 (42.3%) in the psychosomatic medicine departments were diagnosed with SSD. The scores of PHQ-15 in the biomedical, TCM and psychosomatic settings were 11.08 (± 4.54), 11.02 (± 5.27) and 13.26 (± 6.20); PHQ-9 were 10.43 (± 6.42), 11.20 (± 5.46) and 13.42 (± 7.32); GAD-7 were 8.52 (± 6.22), 9.57 (± 5.06) and 10.83 (± 6.24); SSD-12 were 22.26 (± 11.53), 22.98 (± 10.96) and 25.03 (± 11.54) respectively. The scores of PHQ-15, PHQ-9 and GAD-7 in SSD patients were significantly higher in psychosomatic departments than that in biomedical settings (p < 0.05). The cutoff point for SSD-12 was ≥16 in total patients; 16, 16, 17 in biomedical, TCM and psychosomatic settings, respectively. The cutoff point for PHQ-15 was found to be ≥8 in total patients; 8, 9, 11 in biomedical, TCM and psychosomatic settings, respectively.

Conclusion

SSD patients from psychosomatic departments had higher level of somatic symptom severity, depression and anxiety than from TCM and biomedical settings. In our specific sample, a cutoff point of ≥16 for SSD-12 could be recommended in all three settings. But the cutoff point of PHQ-15 differs much between different settings, which was ≥8, 9, and 11 in biomedical, TCM, and psychosomatic settings, respectively.
Case report: Total arch replacement with a frozen elephant trunk utilizing open hybrid in-situ fenestration technique for thoracic aortic arch aneurysm
Authors: Takei Yusuke , Wu I-Hui , Chan Chih-Yang , Chi Nai-Hsin
Published: July 2023

Introduction

The frozen elephant trunk technique is a surgical procedure developed for concomitant repair of downstream descending thoracic aorta as a first stage operation for arch resections. Proximalization of the sutured anastomosis reduces technical difficulty of total arch replacement. In this procedure, an anastomosis is performed more proximally using a stent graft. Connect the head and neck vessels are created using in-situ fenestration method.

Case presentation

This study presents the case of a 78-year-old woman with a large thoracic aortic arch aneurysm that was successfully treated with a modified frozen elephant trunk technique (open in situ fenestration). For this method, a hole was created in the neck branches (the left subclavian artery and left common carotid artery), and peripheral stent grafts were placed to simplify neck branch reconstruction. This minimized the risk of recurrent laryngeal nerve injury and bleeding and shortened the procedure time.

Conclusion

The outcomes of this study showed a safe alternative total arch replacement procedure.

Published: July 2023

Language not only plays a powerful role in human life, as it is also a crucial factor in our minds. It shapes our personality, memory and even the way in which we see the world, as well as playing a fundamental role in the building of self-concept and self-esteem. Having a good self-concept, that is, knowing one’s own qualities and strengths, will, in turn, promote good self-esteem. The aim of this research was to analyze self-concept in 50 children (aged 5–7) with functional dyslalia in the city of Granada (Spain). A quantitative approach was taken, with a non-experimental design; it was descriptive, cross-sectional and correlational. The Perception of Child Self-concept Scale (PCS), a Spanish scale, was used. In general, the children who were interviewed showed a medium level of self-concept. It is noteworthy that differences were found in the average scores on the scale according to the sex of the children, with girls showing a higher level of self-concept than boys. Participants scored higher on Factor 1, family attachment, followed by Factor 3, feelings, with the values of both these factors decreasing with age. On the other hand, lower average scores were found for Factor 2, environment, and Factor 4, autonomy. It was found that self-concept was higher in young children (five-year-old children) as well as in those who studied in rural areas. Finally, guidelines for improvement were provided. Self-concept is a fundamental aspect of personality, but it is not innate; it develops and evolves.
Hair Lipid Structure: Effect of Surfactants
Authors: Coderch Luisa , Alonso Cristina , García M. Teresa , Pérez Lourdes , Martí Meritxell
Published: July 2023

Human hair fibres are mainly comprised of proteins (>90%) and lipids (1–9%), which are characterised as exogenous or endogenous, depending on whether they originate from sebaceous glands or hair matrix cells, respectively. Exogenous lipids consist of free fatty acids (FFAs), triglycerides, cholesterol (CH), wax esters, and squalene. Endogenous hair lipids comprise FFAs, CH, ceramides, glycosylceramides, cholesterol sulfate, and 18-methyleicosanoic acid. Lipids were demonstrated to be fundamental against damage and maintenance of healthy hair. Several studies have evaluated the effects of hair lipid content and have shown how hair properties were altered when lipids were removed by solvent extraction. The effect of surfactants on hair lipids is difficult to determine, as the complex structure of the cell membrane complex makes it difficult to determine where surfactants act. Shampoos and conditioners contain surfactants that remove lipids during routine cleansing of hair. However, shampooing does not completely remove all free lipids from the surface layers. The effect of surfactants on the alteration and removal of structural lipids is poorly developed, and there is no consensus on the results. Further research on the lipid composition of the hair could provide information on the penetration pathways of surfactants to improve effectiveness and limit possible damage.

Published: July 2023

Understanding how Aspergillus oryzae responds to light is critical for developing efficient light regulation strategies in the brewing and waste treatment industries. Although continuous light is known to restrict A. oryzae, little is known about A. oryzae’s sensitivity to light with photoperiod. In this study, we used pulse wave modulation (PWM) to generate nine pulsed blue light (PBL) treatments with varying peak light intensities and frequencies. The effect of PBL on A. oryzae was then compared to that of continuous blue light (CBL). Our findings showed that A. oryzae GDMCC 3.31 mycelium developed faster and produced more conidia under PBL with specific peak intensities and frequencies than under CBL treatment when the light dose and average light intensity were held constant. The colony diameter and conidia count under the two PBL treatments (PL-20_40%_1 Hz and PL-400_20%_10 kHz) were 1.13 and 1.22 times greater than under the CBL treatments, respectively. This different response may be mainly attributed to A. oryzae’s adaptation to the light–dark cycles in nature. Furthermore, an interactive effect was found between peak light intensity and frequency. This work includes pulsed wave modulation as a new factor that influences the A. oryzae photoresponse and recommends it in the development of light regulation methods for fermentation.

Published: July 2023

In this work, the quality parameters of the oils of seven different varieties of olives (Olea europaea cvs, “Arbequina”, “Arbosana”, “Cobrançosa”, “Cornicabra”, “Koroneiki”, “Cacereña”, and “Chiquitita”) grown in hedgerow under cold conditions during three consecutive seasons were analyzed in order to evaluate their adaptation to this growing system. For this purpose, virgin olive oils (VOOs) were extracted, and, in addition to evaluating the indices of hydrolytic, oxidative, and sensory deterioration of the oils, their content in photosynthetic pigments and their composition in fatty acids and phenolic compounds were determined. The correlation between oxidative stability and the parameters evaluated has been studied, with the highest correlation coefficients found for the ratio MUFA/PUFA (0.871) and the content of secoiridoid phenolic compounds (0.816). Furthermore, principal component analysis was performed with the phenolic composition data from each season, which demonstrated the major influence of genetic factors in the phenolic composition of VOO. None of the VOOs presented hydrolytic, oxidative, or sensory deterioration, so all of them remained in the “extra” category. However, it should be noted that the mean ultraviolet absorbance values were significantly higher in “Cornicabra” and significantly lower in “Cacereña” oils. In spite of this, the oxidative stability was significantly higher in “Cornicabra” oils (125 h), which also had the highest mean phenolic content (1035 mg kg−1 oil), while the lowest phenolic content values were found in “Arbequina” and “Chiquitita” (58 and 52 h, respectively).

Published: July 2023

Over the past decade, inorganic fillers and sol–gel-based flame-retardant technologies for textile treatments have gained increasing research interest as useful alternatives to hazardous chemicals previously employed in textile coating and finishing. This review presents the current state of the art of inorganic flame-retardant technology for cotton fabrics to scientists and researchers. Combustion mechanism and flammability, as well as the thermal behavior of neat cotton samples, are first introduced. The main section is focused on assessing the effect of inorganic and sol–gel-based systems on the final flame-retardant properties of cotton fabrics, emphasizing their fire safety characteristics. When compared to organic flame-retardant solutions, inorganic functional fillers have been shown to be more environmentally friendly and pollution-free since they do not emit compounds that are hazardous to ecosystems and humans when burned. Finally, some perspectives and recent advanced research addressing the potential synergism derived from the use of inorganic flame retardants with other environmentally suitable molecules toward a sustainable flame-retardant technological approach are reviewed.
How to Influence Privacy Behavior Using Cognitive Theory and Respective Determinant Factors
Authors: Paspatis Ioannis , Tsohou Aggeliki
Published: July 2023

Several studies have shown that the traditional way of learning is not optimal when we aim to improve ICT users’ actual privacy behaviors. In this research, we present a literature review of the theories that are followed in other fields to modify human behavior. Our findings show that cognitive theory and the health belief model present optimistic results. Further, we examined various learning methods, and we concluded that experiential learning is advantageous compared to other methods. In this paper, we aggregate the privacy behavior determinant factors found in the literature and use cognitive theory to synthesize a theoretical framework. The proposed framework can be beneficial to educational policymakers and practitioners in institutions such as public and private schools and universities. Also, our framework provides a fertile ground for more research on experiential privacy learning and privacy behavior enhancement.
Encoding Variables, Evaluation Criteria, and Evaluation Methods for Data Physicalisations: A Review
Authors: Ranasinghe Champika , Degbelo Auriol
Published: July 2023

Data physicalisations, or physical visualisations, represent data physically, using variable properties of physical media. As an emerging area, Data physicalisation research needs conceptual foundations to support thinking about and designing new physical representations of data and evaluating them. Yet, it remains unclear at the moment (i) what encoding variables are at the designer’s disposal during the creation of physicalisations, (ii) what evaluation criteria could be useful, and (iii) what methods can be used to evaluate physicalisations. This article addresses these three questions through a narrative review and a systematic review. The narrative review draws on the literature from Information Visualisation, HCI and Cartography to provide a holistic view of encoding variables for data. The systematic review looks closely into the evaluation criteria and methods that can be used to evaluate data physicalisations. Both reviews offer a conceptual framework for researchers and designers interested in designing and evaluating data physicalisations. The framework can be used as a common vocabulary to describe physicalisations and to identify design opportunities. We also proposed a seven-stage model for designing and evaluating physical data representations. The model can be used to guide the design of physicalisations and ideate along the stages identified. The evaluation criteria and methods extracted during the work can inform the assessment of existing and future data physicalisation artefacts.

Direct pulp capping (DPC) is reliable in pulp exposure management. Objective: This study aimed to assess the success rate of DPC materials and different laser protocols. The included procedures were CO2 laser (n = 1147), Er: YAG laser (n = 69), and 980 nm diode laser (n = 124), on the one hand, and Ca (OH)2 (n = 376) and bioactive tricalcium silicate paste, on the other (n = 279). Materials and methods: Data from 1995 DPC cases were included. For laser groups, irradiation was used to coagulate the pulp exposure followed by Ca (OH)2 placement. Data with follow-up at 12, 24, and 36 months post-treatment were included. The irradiation parameters for the CO2 laser were as follows: energy density per pulse of 141 J/cm², 1 W power, 0.3 mm beam diameter, 100 ms pulse duration, and 1 Hz, and a series of five pulses maximum were delivered during 5 s. For the 980 diode lasers: 1.5 W power, continuous wave (CW), 400 μm fiber diameter, contact mode, 190.98 W/cm2 power density, and total delivered energy density of 2387 J/cm2. For the Er: YAG laser: 0.5 W output power, 9.95 J/cm2 energy density, a beam diameter of 0.8 mm, 300 µsec pulse duration, 10 Hz, non-contact mode, irradiation with air without water spray, and an average irradiation time of 8–10 s. Results: At the 3-year follow-up, the success percentages were as follows: CO2 (88.01%) > Ca (OH)2 (75.72%) > diode (70.01%) > Er: YAG (54.55%) > bioactive tricalcium silicate paste (51.1%). The timing of permanent filling (immediate or delayed), patient age, size of pulp exposure, tooth type, and exposure etiology significantly affected the success rate. Patients aged ≤ 35 years presented higher success (70.91%) compared to those ≥ 36 years (61.2%). Immediate permanent fillings increase the success rate (71.41%) compared to delayed permanent fillings (65.93%). Exposure in molars and premolars significantly lowers the success rate (60.3%) compared to canines and incisors (72.1%). Idiopathic pulp exposure presented higher success (72.58%) compared to caries-related causes (63.7%). Conclusion: The highest success rate was in the CO2 laser group followed by the diode and Ca (OH)2, Er: YAG, and bioactive tricalcium silicate material (biodentine) groups. The age factor, filling timing, size of exposure, tooth type, and exposure etiology can significantly affect the success rate of DPC.
Urban Land Use Survey Methods: A Discussion on Their Evolution
Authors: Pissourios Ioannis A.
Published: July 2023

Although the tradition of surveying and analyzing urban land uses for town planning purposes dates back to the 19th century, the evolution of survey methods has not been studied in detail. With the intention of filling this gap, the present article reviews the pertinent Anglo-American literature on survey methods, published from the beginning of the 20th century to date, and highlights the key contributions. Additionally, it proposes a periodization of the methodological evolution in three phases and identifies the main discussions developed on survey methodology, so as to provide a basis for more structured research on the subject matter.
Cutaneous Malignant Melanoma with Testicular Metastases in a Wild Rabbit (Oryctolagus cuniculus)
Authors: Abbate Jessica Maria , Palazzolo Simone , Ieni Antonio , Rapisarda Giuseppe Santi , Lanteri Giovanni
Published: July 2023

Melanocytic skin tumours have been rarely described in pet rabbits, and exposure to UV light in sparsely haired areas has been hypothesised to play a cancerogenic role. Here, we describe a case of cutaneous malignant melanoma arising from the skin of the scrotum in an 8-year-old male wild rabbit, with testicular metastases as an unusual metastatic site for melanoma reported in humans to date. The tumour was nearly 5 cm in size, firm, and highly pigmented, with multifocal superficial ulcerations and large areas of intratumoural necrosis. The adjacent testis was 1.5 cm, multinodular, and black, obscuring tissue morphology. Histologically, the dermis was expanded by an infiltrative, densely cellular neoplasm composed of nests and sheets of polygonal to spindle neoplastic melanocytes, supported by scant fibrovascular stroma. Neoplastic cells showed intermediate N/C ratio, moderate basophilic cytoplasm, often obscured by abundant brownish granular pigment, and eccentric nuclei with prominent nucleoli. Cellular pleomorphism and nuclear atypia were severe, and high mitotic activity was observed. Diffuse dermal lymphovascular invasion was also observed. The testis was delimited by a thin tunica albuginea, and the parenchyma was largely obscured in its morphology by densely packed neoplastic cells. Seminiferous tubules, lined with a thin basement membrane and containing neoplastic and scattered spermatogenic cells, were occasionally observed. Neoplastic cells within the skin and the testis were positive for HMB-45, Melan-A, and S-100. The growing popularity of rabbits as pets allows for a greater ability to accumulate data on the spontaneous occurrence of tumours in these animals. Furthermore, descriptions of the biological aspects of spontaneously occurring tumours may serve to improve current knowledge in animal species and humans in which the same neoplasm may occur.
La face inappropriable de la Terre. Une autre façon d'instituer le rapport au sol et aux choses (Afrique de l'ouest)
Authors: Liberski-Bagnoud Danouta
Published: July 2023

Une privatisation et une concentration sans précédent des terres arables de la planète touche l’Afrique subsaharienne de plein fouet. L’une des solutions proposées pour tenter, sinon de mettre un frein à cette ruée verte, du moins d’en pallier les conséquences néfastes qu’elle ne manque pas d’entraîner sur les populations ainsi dépossédées de leurs modes d’existence, est d’intensifier l’implantation du droit de propriété privée foncière en cette partie du monde. Cette proposition ne manque pas d’être paradoxale alors même que l’idéologie propriétaire fait l’objet d’une analyse critique de plus en plus acérée au Nord, en ce qu’elle est, précisément, au coeur de la privatisation actuelle des moyens de subsistance d’une partie de l’humanité. Il est urgent de reconnaître l’intelligence des systèmes de pensée de ces sociétés délogées pour des enjeux qui ne sont pas les leurs, et d’en tirer les leçons qui s’imposent. Depuis notre poste d’observation auprès de sociétés d’agriculteurs sédentaires du Burkina Faso, il s’agira de montrer qu’en accordant à la notion d’inappropriable une place centrale dans les montages rituels qui instituent le rapport au sol et aux choses, ces sociétés réaffirment et préservent la relation d’imbrication de l’homme et du monde. Elles rappellent que la Terre n’est pas seulement ce qui fournit à l’homme les éléments de sa survie, mais qu’elle est aussi ces lieux qui l’abritent, les paysages qu’il parle ou compose, mais aussi, encore plus fondamentalement, ce qui le définit dans sa corporéité même.

Published: July 2023

En la selva baja caducifolia durante la época de secas, la disponibilidad de los pastos se ve reducida en calidad y cantidad. En los pastos nativos e introducidos el contenido y disponibilidad de proteína cruda y minerales como Ca y P se reduce. Por sus características nutricionales, el follaje verde de las especies arbóreas puede ser una fuente importante de alimento para el ganado. El objetivo del presente trabajo fue determinar la composición química del follaje verde de las nuevas especies arbóreas nativas con potencial forrajero en la Región de Tierra Caliente. Se aplicaron encuestas a 15 ganaderos, en cada uno de los municipios que constituyeron el área de estudio: Carácuaro, Huetamo y San Lucas, del estado de Michoacán. Los productores encuestados refirieron la existencia de 73 árboles que no habían sido referidos previamente. A 67 de ellos se les determinó, proteína cruda, fibra detergente neutra, fibra detergente ácida, materia orgánica, cenizas, calcio y fósforo. De las especies evaluadas en el presente estudio, 98.53% de las especies presentaron niveles mayores a 8% de proteína cruda; 61.19% presentaron concentraciones entre 49.54% a 59.58% de FDN, por lo que se esperaría presenten niveles aceptables de digestibilidad. La mayoría de las especies (74.63%) presentaron en promedio 0.21% de fósforo, lo cual contrasta con el rastrojo de maíz que aporta sólo el 0.10% de este mineral. La diversidad y el contenido químico de las especies evaluadas, aporta un juicio nutricional preliminar para su uso en la alimentación como una fuente de forraje de calidad y complementación en la dieta de los rumiantes durante la época de estiaje permitiendo prácticas productivas sustentables para el desarrollo de la ganadería.

Published: July 2023

En el estado de Quintana Roo, México, la producción de chile jalapeño se caracteriza por el uso de materiales criollos de tamaño chico y mediano con una amplia variación en la forma del fruto. El tamaño del fruto puede ser una limitante en la comercialización, las innovaciones tecnológicas como el uso de variedades con mejor calidad de fruto pueden incrementar la competitividad de la cadena de valor del chile jalapeño, sin embargo, es necesario conocer las preferencias de los comercializadores, por lo que el objetivo de este trabajo fue recabar información sobre las características de calidad de fruto que son requeridas a los productores por parte de los acopiadores de chile jalapeño.

Se diseñó una encuesta sobre la base de un cuestionario de preguntas de opción múltiple considerando los atributos de calidad de productos frescos que incluyen la apariencia, textura, sabor y el componente de seguridad alimentaria. La encuesta a productores se realizó en mayo de 2023, la encuesta a comercializadores se realizó en junio de 2023.

Se encontró que los productores cultivan a pequeña escala, el rango de superficie de parcela va de 0.5 ha a 4.0 ha. Los productores producen fruto de tamaño chico y mediano, pero no es una limitante dado que los comercializadores acopian fruto de este tamaño para sus clientes que procesan el jalapeño. La obtención de frutos de tamaño grande y extragrande no tendría dificultades para su comercialización, los comercializadores pueden desplazar frutos de este tamaño, aunque es necesario un volumen mínimo de 13 a 14 toneladas.

No hay ninguna preferencia por la forma del fruto, en el color se prefieren frutos de color verde esmeralda. Se prefieren frutos sin corchosidad pero se aceptan frutos hasta con 25 % de corchosidad. El 100% de los productores encuestados manifestaron que sus compradores les piden frutos enteros, frutos sanos exentos de podredumbre, limpios y exentos de plagas y enfermedades. Los comercializadores reportan que el cliente para quien acopian solicitan que los frutos cumplan con el intervalo de seguridad de los plaguicidas utilizados.

La cruza manual entre materiales nativos de tomate es una forma de aumentar la variación genética. Antes de realizar los cruzamientos se requiere conocer el momento oportuno en base a las condiciones del medio ambiente, para lograr el mayor porcentaje de amarre de fruto y, por consiguiente, éxito en el mejoramiento genético. El objetivo fue realizar cruzamientos manuales entre poblaciones de tomate nativo bajo las condiciones ambientales del Campo Experimental Zacatepec, Morelos, México como base esencial para emprender su mejora genética. Se seleccionaron flores en estado de botón, se eliminaron estambres, dejando solamente las estructuras femeninas. De tres a cinco días después, se revisó el desarrollo biológico de los estigmas, cuando se mostró receptivo se llevó a cabo la polinización, del 21 de septiembre al 10 de octubre del 2022, de 10:30 a.m. a 13:00 p.m. El material genético fueron aproximadamente 40 progenitores. Se registró la temperatura y la humedad relativa. El porcentaje de amarre de frutos fue la variable respuesta. Durante 20 días se realizó 67 cruzas manuales. El porcentaje de amarre de frutos fue muy variable. El menor fue de 33% y el mayor de 100%. La temperatura promedio que se presentó fue de 29.68 °C y la humedad relativa de 64.19%. En las horas de la polinización fue aumentando la temperatura y la humedad relativa fue disminuyendo. Los dos factores principales que afectan el amarre de frutos son la temperatura y la humedad relativa. Estos resultados representan la base fundamental para emprender el mejoramiento genético de tomate nativo mexicano.

Objective. Characterize the fungal coenosis of the root zone of soybean plants and investigate the functional effect of isolated micromycetes on plants. Methods. The mycocenosis of different spheres of the root zone of soybean plants was studied under the conditions of field experiments on sod-medium-podzolic dusty-sandy soil. Soil sampling, isolation, accounting and cultivation of fungi were carried out according to generally accepted methods. Measuring the number of micromycetes in the spacing and the rhizosphere of soybean was carried out by the Waksman’s soil dilutions method. To extract mycobiota of rhizoplane, the method of washing from the surface of soybean roots, followed by dilution and deep sowing in the digest medium was used. Endophytes were isolated from the tissues of healthy unaffected soybean roots after their surface sterilization with alcohol (96%) for 1.5 min. Cultural and morphological characteristics of fungi were studied on wort agar, Chapek's agar medium, and potato-glucose agar. Their identification was carried out according to the determinants appropriate for a specific systematic group of micromycetes. The functional effect of micromycetes on plants was evaluated using bioassays on corn seedlings. Results. The mycocenosis of sod-podzolic soil was formed by micromycetes belonging to the genera Acremonium Link, Alternaria Nees, Cladosporium Corda, Fusarium Link:Fr, Gliocladium Corda, Mortierella Coem, Mucor Mich, Penicillium Link:Fr, Rhizopus Ehrenb, Trichoderma Hers, among which micromycetes of the genus Penicillium (28.05 ± 3.13 thous CFU per 1 g of dry soil) were the most common. Under the influence of root exudates, the total number of soya bean rhizospheric soil fungi increased threefold and amounted to 212.30 ± 16.73 thous CFU per 1 g of dry soil; in the rhizosphere fungi of the genus Fusarium prevailed (152.63 ± 13.27 thous CFU per 1 g of dry soil). Mycocenosis of the rhizoplane of soybean plants was qualitatively and quantitatively depleted, as compared to the rhizosphere, and consisted mainly of representatives of the genera Fusarium (10.18 ± 3.93 thous CFU per 1 g of dry roots) and Gliocladium (6.88 ± 1.20 thous CFU per 1 g of dry roots). The endophytic mycobiota of soybean was formed by micromycetes of the genera Penicillium (44 %), Chaetomium (21 %), Fusarium (21 %), Verticillium (7 %), Phoma (7 %). Micromycetes isolated from the root zone of soybean plants differed in their functional effect on plants. The largest share of the studied fungi (61 %) are producers of growth-stimulating substances of various origin, 18 % of strains are characterized by a phytotoxic effect on plants, 21 % do not have a pronounced effect on plants. Conclusion. The fungal coenosis of the root zone of soybean was characterized, the functional effect of isolated micromycetes on plants was investigated.

Introduction: Acute haematogenous osteomyelitis (AHO) of the acetabulum is a rare condition in children. Presentation of case: We report a rare case in a ten-year-old child who had an acute presentation with new-onset hip pain and fever evolving for one week. The standard radiograph was without abnormalities. Emergency MRI showed osteoarthritis of the hip, with a 15 mm internal acetabular subchondral lacuna. Therefore, the child had antibiotic therapy. Pain relief and radiological improvement was obtained after 3 months of antibiotic treatment. At a two-year follow-up, the X-ray was normal. Discussion: Diagnosis is delayed because of the deep-seated location. Staphylococcus aureus is the most common causative organism. In the event of strong clinical-radiological suspicion, empirical treatment must be started rapidly, in order to obtain satisfactory results. Conclusion: Because of the atypical location of acute osteomyelitis of the acetabulum, diagnosis can be delayed. In some cases, treatment may be based on antibiotics therapy alone.

Pre-trained CNN-based TransUNet Model for Mixed-Type Defects in Wafer Maps
Authors: Kim Youngjae , Lee Jee-Hyong , Jeong Jongpil
Published: July 2023

Classifying the patterns of defects in semiconductors is critical to finding the root cause of production defects. Especially as the concentration density and design complexity of semiconductor wafers increase, so do the size and severity of defects. The increased likelihood of mixed defects makes finding them more complex than traditional wafer defect detection methods. Manually inspecting wafers for defects is costly, creating a need for automated, artificial intelligence (AI)-based computer vision approaches. Previous research on defect analysis has several limitations, including low accuracy. To analyze mixed-type defects, existing research requires a separate model to be trained for each defect type, which is not scalable. In this paper, we propose a model for segmenting mixed defects by applying a pre-trained CNN-based TransUNet using N-pair contrastive loss. The proposed method allows you to extract an enhanced feature by repressing extraneous features and concentrating attention on the defects you want to discover. We evaluated the model on the Mixed-WM38 dataset with 38,015 images. The results of our experiments indicate that the suggested model performs better than previous works with an accuracy of 0.995 and an F1-Score of 0.995.
Optimizing the reinforcement of buildings and structures in automatic design processes
Authors: Kvasnikov A. A. , Sumarokov E. V.
Published: July 2023

Introduction. Reinforcement is one of the most important processes in designing reinforced concrete structures. The need to optimize the reinforcement process arises from the constant increase in the volume and complexity of construction projects, as well as from the economy and efficiency requirements. In this regard, automatic design processes are becoming increasingly relevant, being conducive to significant acceleration and improvement of the quality of these works. Other areas of civil and industrial construction are also adopting automatic design processes in order to reduce construction and production costs. Mixed Integer Programming (MIP), Simplex Method (SM), and Genetic Algorithm (GA) are commonly used.

Aim: to develop an algorithm for optimizing the reinforcement process of reinforced concrete structures of buildings and structures and to design a program for automating the process.

Materials and methods. The paper relies upon the results of the calculations performed by the authors in the Lira program. Furthermore, the authors created a digital information model of the building in the Revit program. The Python programming language was used to test the results. A ready-made solution was created in C# using RevitAPI.

Results. The paper substantiates the relevance and demonstrates the feasibility of optimization of technological solutions in the process of designing buildings and structures made of reinforced concrete according to the criterion “reliability – efficiency”. To this end, existing design software was integrated into a single modeling and design module, and the necessary software was proposed for development. The genetic algorithm was chosen as the main method for optimizing the reinforcement of structures. Tools for processing the calculation results, creating a duplicate of the calculation model in the design environment and analyzing the calculations were elaborated.

Conclusion. The selected genetic algorithm accelerates the design process, and saves time when designing reinforced concrete structures. The results of the study are instrumental in developing the software for the automation of reinforcement.
Steel savings in an industrial building column with account for effect of crane girder stiffness
Authors: Farfel M. I. , Mikhailik E. D.
Published: July 2023

Introduction. Construction science always seeks to save materials, including in the design of steel frameworks. Currently, in modern construction standards, structural analysis of frameworks for industrial buildings, namely their columns, is carried out without considering the stiffness of the crane girder which receives the load from the overhead crane. However, this factor can give a certain economy of metal, since the stiffness of crane structures directly affects the stability of columns of industrial buildings, and therefore the metal consumption of the framework.

Aim. To achieve savings of steel due to taking into account the effect of crane girder stiffness on the stability of an industrial building framework.

Materials and methods. For these purposes, the authors of the paper used classical methods of structural mechanics. A programmed cyclic algorithm of the Mathcad software was used to find the critical forces and effective length coefficients at various stiffnesses of the column elements. Columns of an industrial building are usually two-member. Given that, its structural design is twice statically indeterminate by the deflection method. The bearing capacity of an industrial building column is found by deriving the critical force, which is determined from the equation obtained by setting equal to zero the stability determinant consisting of the coefficients of the linear equation system by the deflection method. In addition, the effective length coefficient for the upper and lower parts of the column is determined. The paper compares the results obtained with the scheme without taking into account the crane girder.

Results. Considering the effect of the crane girder stiffness enabled the material consumption of the column to be reduced by 30 %. Critical forces and effective length coefficients were found at various stiffnesses of the column elements, using a programmed cyclic algorithm of the Mathcad software.

Conclusion. Taking into account the stiffness in the structures of the elements in the industrial building frameworks reduces metal consumption.
