Published: October 2023

X-ray fluorescence spectroscopy, scanning electron microscopy energy spectrum, excitation-emission matrix spectroscopy, and Fourier transform infrared spectroscopy was applied to the unearthed jade with multilayered corrosion, to reveal the microstructure, composition structure, and distribution of organic matters. Our results showed that the interior of the jade was mainly composed of layered serpentine with a regular structure, while the white layer structure on the surface is scattered and irregular, and the content of calcite formed by elements Ca and C increases significantly; between the green matrix and the white layer on the surface, there are brown corrosion zones with obvious fluorescence effect and mainly composed of humic acid, which continuously extends inward along the corrosion cracks for accelerating the internal corrosion. This article, for the first time, argued for the corrosive and fluorescent humic acid bands that appear inside serpentine jade and cautions its role in investigating the corrosion of jade.

Published: October 2023

Objectives

This study aims to establish nomograms to accurately predict the overall survival (OS) and progression-free survival (PFS) in patients with non-small cell lung cancer (NSCLC) who received chemotherapy alone as the first-line treatment.

Materials and methods

In a training cohort of 121 NSCLC patients, radiomic features were extracted, selected from intra- and peri-tumoral regions, and used to build signatures (S1 and S2) using a Cox regression model. Deep learning features were obtained from three convolutional neural networks and utilized to build signatures (S3, S4, and S5) that were stratified into over- and under-expression subgroups for survival risk using X-tile. After univariate and multivariate Cox regression analyses, a nomogram incorporating the tumor, node, and metastasis (TNM) stages, radiomic signature, and deep learning signature was established to predict OS and PFS, respectively. The performance was validated using an independent cohort (61 patients).

Results

TNM stages, S2 and S3 were identified as the significant prognosis factors for both OS and PFS; S2 (OS: (HR (95%), 2.26 (1.40–3.67); PFS: (HR (95%), 2.23 (1.36–3.65)) demonstrated the best ability in discriminating patients with over- and under-expression. For the OS nomogram, the C-index (95% CI) was 0.74 (0.70–0.79) and 0.72 (0.67–0.78) in the training and validation cohorts, respectively; for the PFS nomogram, the C-index (95% CI) was 0.71 (0.68–0.81) and 0.72 (0.66–0.79). The calibration curves for the 3- and 5-year OS and PFS were in acceptable agreement between the predicted and observed survival. The established nomogram presented a higher overall net benefit than the TNM stage for predicting both OS and PFS.

Conclusion

By integrating the TNM stage, CT radiomic signature, and deep learning signatures, the established nomograms can predict the individual prognosis of NSCLC patients who received chemotherapy. The integrated nomogram has the potential to improve the individualized treatment and precise management of NSCLC patients.

Published: October 2023

Background

Telemedicine has a great role in delivering clinical services when distance and time are critical factors. Although this tool does not replace a medical examination, it was inevitably needed service during COVID-19 pandemic as it avoided the need for a patient’s visit, particularly at times when confinement measures are being enforced. As technology is sweeping the earth, the role of telemedicine should be evaluated precisely as an ongoing service with great emphasis on patient’s satisfaction.

Patients and methods

Participants of telepsychiatric services using Ain Shams University platform for three consecutive months (July, August, and September 2021) were enrolled in the study. Data were collected using Google form, and patients were approached via telephone calls. De novo questionnaire for assessing patient’s satisfaction was conducted in Arabic to assess patient satisfaction.

Results

A total of 104 participants receiving video consultation. Positive attitude towards remote consultations was concluded, where 80.8% (84) of the patients were satisfied from telepsychiatry services.

Conclusion

Our study highlights high degree of satisfaction among patients receiving telepsychiatry consultations provided by Okasha Institute of Psychiatry, Ain Shams University, Egypt.
The complexities in diagnosing intradiaphragmatic extrapulmonary sequestration: a case report
Authors: Ramos Anna-Kaelle K. J. , Teramae Tori R. , Liang Collin G. Z. , Brazer Miriam L. , Woo Russell K.
Published: October 2023

Background

Extralobar pulmonary sequestration–a congenital lung malformation characterized by nonfunctional lung tissue with its own visceral pleura and without a connection to the normal tracheobronchial tree–is often surgically resected given the potential for infectious complications. We report a case of a child with extralobar pulmonary sequestration in a rare and challenging intradiaphragmatic location, which made preoperative identification and planning difficult.

Case presentation

A 2-year-old boy presented for follow-up of a large left extralobar pulmonary sequestration initially diagnosed on an antenatal ultrasound. Follow-up imaging, including prenatal MRI and postnatal CT angiography, was inconclusive on the precise location of the extralobar pulmonary sequestration in relation to the diaphragm but did reveal a subdiaphragmatic arterial supply from a branch off the celiac trunk. Planned resection with diagnostic thoracoscopy revealed the mass to seemingly be below the diaphragm; however, subsequent abdominal laparoscopy identified it to be within the diaphragm. Once the supplying vessel off the celiac trunk was controlled and divided, the mass was circumferentially excised from the edges of the diaphragmatic muscle. The remaining diaphragmatic defect was then closed, and the patient did well postoperatively.

Conclusions

This case demonstrates the difficulty of making a definitive diagnosis of intradiaphragmatic extralobar pulmonary sequestration without operative intervention. CT angiography and identification of the sequestration’s arterial supply may not be conclusive in determining the precise location if in close proximity to the diaphragm.

Authors: Channawi Ali , Pop Florin-Catalin , Khaled Charif , Gomez Maria Galdon , Moreau Michel , Polastro Laura , Veys Isabelle , Liberale Gabriel
Published: October 2023

Background

The most common mode of ovarian cancer (OC) spread is intraperitoneal dissemination, with the peritoneum as the primary site of metastasis. Cytoreductive surgery (CRS) with chemotherapy is the primary treatment. When necessary, a digestive resection can be performed, but the role of mesenteric lymph nodes (MLNs) in advanced OC remains unclear, and its significance in treatment and follow-up evaluation remains to be determined. This study aimed to evaluate the prevalence of MLN involvement in patients who underwent digestive resection for OC peritoneal metastases (PM) and to investigate its potential prognostic value.

Methods

This retrospective, descriptive study included patients who underwent CRS with curative intent for OC with PM between 1 January 2007 and 31 December 2020. The study assessed MLN status and other clinicopathologic features to determine their prognostic value in relation to overall survival (OS) and progression-free survival (PFS).

Results

The study enrolled 159 women with advanced OC, 77 (48.4%) of whom had a digestive resection. For 61.1% of the patients who underwent digestive resection, MLNs were examined and found to be positive in 56.8%. No statistically significant associations were found between MLN status and OS (p = 0.497) or PFS ((p = 0.659).

Conclusions

In anatomopathologic studies, MLNs are not systematically investigated but are frequently involved. In the current study, no statistically significant associations were found between MLN status and OS or PFS. Further prospective studies with a systematic and standardized approach should be performed to confirm these findings.
Nonbinary Epistemologies: Refusing Colonial Amnesia and Erasure of Jotería and Trans* Latinidades
Authors: Salas-SantaCruz Omi
Published: October 2023

Abstract: The author reflects on the experiences of teaching a Trans* Latinx studies course, where students initially expressed discontent with the syllabus for lacking legible trans subjects. By engaging with decolonial methodologies and theories, the author highlights the limitations of “looking for” (Lugones 2020) trans in traditional archives and theories. The author discusses the importance of embracing the nonsense within the pluriverse of affective belonging and recognizing the possibilities that emerge within the nonsensical and nonbinary theoretical subjectivities that challenge conventional understandings of transgender phenomena. Engaging with U.S. women of color feminist theorizing—rooted in Black, Latinx, Indigenous, and decolonial feminisms—the author discusses the importance of nonbinary thinking practices in confronting the epistemology of ignorance in trans studies. Drawing upon the works of various decolonial and trans* of color scholars, this paper explores the complex diasporic relationality of jotería as a way of existing within coloniality, offering a critical lens to examine the diverse dimensions of queer and trans Latinx life. Nonbinary thinking, in this context, is essential for learning from, alongside, and within oppressed trans of color knowledge, theories, strategies, and ways of existing grounded in particular cosmologies, geographies, histories, and cultures. It also represents a vital political strategy for avoiding and refusing discursive colonization.
Gender Transgressions: Nonbinary Spaces in Greco-Roman Antiquity and Ancient China
Authors: Rich Lou
Published: October 2023

Abstract: Nonbinary presentations, behaviors, and spaces have been observed transculturally throughout history. Whilst historical manifestations differ from our modern notions of nonbinary, this article examines instances of nonbinary transgressions that may have been previously consigned to homoerotic histories. This article deploys such a nonbinary lens to discuss instances that relate to the body, gender presentations, social roles, and language, for the purpose of problematizing both notions of trans-gender history and binary assumptions of gender as untransmutable and immutable.
Transition and Trans*lation beyond Binary History in Mid-century Upper Egypt; or, Portraits of Transfemininity in Asyut
Authors: Botros Beshouy
Published: October 2023

Abstract: In 1958, the popular Egyptian magazine Ākhir Sā`ah ran a story about four people designated “men donning dresses and living as women” in the Upper Egyptian town of Asyut. Ākhir Sā`ah presented brief profiles explaining these people’s gender expression alongside staged photographs and opinions from an Egyptian psychiatrist, the local minister of education, a lawyer, and a social scientist. This article departs from that one. By annotating my trans*lation of the Arabic text, I interrupt its binary logics. Trans*lation is an idiomatic meaning-making process that is in intimate dialogue with the process of transition itself. In the source text, Egyptians living in tension with the gender binary were made legible through the relay of pseudoscientific evidence and details about their early childhood experiences, or in one instance, through a story about a deal between the subject and a spirit, a jinn. My analysis denaturalizes the publication’s ethnographic documentation and teleological narration of these people’s lives. Working through the Arabic text and departing from the Orientalist fixation with philology, I consider the possibilities of rendering gender alterity across languages and employ trans*lation as a method to engage narratological and historiographical processes. In my treatment of these biographies, I clarify how “nonbinary” challenges the emplotment of gender transition and the work of translation as linear processes, and I motion towards its potential to evacuate the overlapping transitions to modernity and the emergence of the postcolonial nation-state, which the aforementioned transfeminine individuals also lived, from similarly teleological narrations and binary logics. Ultimately, I situate these four subjects beyond the interlocking binaries of man/woman, human/spirit, cis/trans, modern/traditional, and East/West. In so doing, I collapse these structures and offer alternative portraits of transfemininity in Asyut.
Desi Genderqueerness: The Mystery and History of Gender Diversity in India
Authors: Bora Raagini
Published: October 2023

Abstract: The goal of this article is to conceptualize a decolonial understanding of an Indian genderqueerness, trying to contest the false temporal binaries of coloniality and postcoloniality. Tracing India’s complex and rich queer and genderqueer history preceding British colonization, I dissect the impact of colonization on postcolonial transphobia and understandings of trans. Through a historical literature review and media content analysis of the controversial film The Pink Mirror (2003), I apply a decolonial lens to reimagine locally produced narratives of queerness and genderqueerness through local genderqueer communities, such as Hijras and Kothis.
Queerly Comprehensible: The Nonbinary Art of Kris Grey
Authors: Straayer Chris
Published: October 2023

Abstract: This essay argues that nonbinary artist Kris Grey deploys a genderqueer aesthetic to undo taxonomy. Their ceramic sculpture and performance art cross and diffuse binaries through reversals, implosions, conversations, and invitations. I contextualize Grey’s art within the work of other contemporary artists who have creatively investigated and engineered gender, sex, and sexuality. Following Vittorio Gallese, I argue that Grey’s embodied images haptically share nonbinary physicality with audiences. Through centrifugal and centripetal reconfigurations, they make new experiences visible, imaginable, and available. Following Caroline Walker Bynum, I argue that by queerly foregrounding the nonbinary underpinning of a master aesthetic discourse, Grey shows the seemingly unfamiliar nonbinary body to be affectively comprehensible.
The Nonbinary Blackness of Pauli Murray and Ornette Coleman: Constraint and Freedom within the Glandular Imaginary
Authors: Stryker Susan
Published: October 2023

Abstract: This short essay reflects on desires for body modification expressed by civil rights activist Pauli Murray and jazz innovator Ornette Coleman to offer some preliminary thoughts on the concept of “nonbinary Blackness.” It compares the different ways Murray and Coleman negotiated the “glandular imaginary” that informed mid-twentieth-century ideas about sex, gender, and identity, and influenced decisions they made about their own bodies. The transmasculine Murray reconciled to living as a woman once medical examinations determined that there was no hormonal or gonadal cause for her/their masculine identifications, while Coleman, a seemingly cisgender man, drew creative insight from his decision to undergo the genital surgery of circumcision.
An ERP implementation on a beekeeping and honey value chain
Authors: Ojeda John Marcelo , Rossit Daniel Alejandro , Toncovich Adrián Andrés
Published: October 2023

Goal: This research represents a case study on the selection and implementation of ERP systems in the beekeeping and honey production sector, developing a decentralized and digital system accessible to every stakeholder in a cooperative based in the province of Buenos Aires, Argentina.
Methodology: The work develops an in-depth analysis of the beekeeping activities and how farmers participate and interact with the cooperative. This enables to distinguish the main features and specifications that an ERP system must have to give proper support to the business functions within the cooperative.
Results: This implementation made it possible to make the production process more flexible, improve the traceability of production batches, and reduce costs in the business operation.
Limitations: To generalize the results, other experiences from similar organizations should be incorporated. In addition, it would be convenient to reassess the situation when the implementation is fully developed, since this article presents the implementation of essential and critic modules for the operation of the organization.
Practical implications: A special feature of this study is that the organization is structured as a cooperative, then each producer is a stakeholder in the system meaning that the decision-making processes are decentralized and transparent to each stakeholder.
Originality: This study represents a novel development in using cloud and digital technologies to leverage and foster horizontal organizations such as cooperatives. Digitalization enables to share the information and decisions made by each of the stakeholders, something that strengthens the main purpose of cooperatives. As far as we know, there are no previous studies on developing ERP systems for an agricultural cooperative.

Published: October 2023

This study investigates the effect of aeration rate and feedstock density on the biodrying process to improve the quality of type 2 wet refuse-derived fuel. The aeration rate and feedstock density were varied to investigate these parameters’ effect on the system’s performance. The experiments used 0.3 m3 lysimeters with continuous negative ventilation and five days of operation. In Experiment A, aeration rates of 0.4, 0.5, and 0.6 m3/kg/day were tested with a feedstock bulk density of 232 kg/m3. In Experiment B, the optimum aeration rates determined in Experiment A (0.5 and 0.6 m3/kg/day) were used, and the feedstock density was varied (232 kg/m3, 250 kg/m3, and 270 kg/m3). The results showed that an aeration rate of 0.5 m3/kg/day was the most efficient for a feedstock density of 232 kg/m3; when the aeration rate was increased to 0.6 m3/kg/day, a feedstock density of 250 kg/m3 was the most effective. However, a feedstock density of 270 kg/m3 was not found to be practical for use in the quality improvement system. When the feedstock density is increased, the water in the feedstock and the water resulting from the biodegradation process cannot evaporate due to the feedstock layer’s low porosity, and the system requires an increased aeration rate. Furthermore, the increase in density scaled with increased initial volatile solid content, initial organic content, and initial moisture content, which significantly impacted the final moisture content based on multivariate regression analysis.
Photovoltaic power prediction based on sky images and tokens-to-token vision transformer
Authors: Dai Qiangsheng , Huo Xuesong , Su Dawei , Cui Zhiwei
Published: October 2023

Photovoltaic (PV) power generation has high uncertainties due to the randomness and imbalance nature of solar energy and meteorological parameters. Hence, accurate PV power forecasts are essential in the operation of PV power plants (PVPP) for short-term dispatches and power generation schedules. In this paper, a new deep neural network structure based on vision transformer is proposed to combine sky images and Tokens-To-Token（T2T） for photovoltaic power prediction. The method uses an incremental tokenization module to aggregate neighboring image patches into tokens, which capture the local structural information of the clouds. Then, an efficient T2T-ViT backbone network is used to extract the global attentional relationships of the tokens for power prediction. In order to evaluate the performance of the proposed model, the method was compared with several deep learning architectures such as ResNet and GoogleNet on a dataset collected by the National Renewable Energy Laboratory in Colorado, USA. The results of power prediction were analysed using training loss, prediction error, and linear regression, and they show that the proposed method achieves higher prediction accuracy and lower error compared to the existing methods, especially in short- and ultra-short-term prediction. The paper demonstrates the potential of applying Transformer models to computer vision tasks for renewable energy forecasting. The results show that the proposed method achieves higher prediction accuracy and lower error than several deep learning architectures, such as ResNet and GoogleNet, especially in short- and ultra-short-term prediction.

Authors: Hardianto Eko , Satriyo Tony Budi
Published: October 2023

The Asian monsoon scallop, Amusium pleuronectes, is a key member of shellfish communities that are the most commercially harvested in Asia. Materials were obtained from four sites in Indonesia: Semarang, Bali Island, Maros and Buru Island. Nucleotide sequence analysis was performed on PCR-amplified mitochondrial DNA 16S rRNA. In total, 556-558 base pair nucleotide sequences were obtained from 8 individuals. Molecular analyses revealed that the samples belong to the A. pleuronectes species. Phylogenetic analyses were carried out by comparing the gene sequences of A. pleuronectes haplotypes in Indonesia with gene sequences of the same base pair length and with the of A. japonicum which was used as an outgroup. The phylogenetic trees were consistent and indicated in the two sub-clades. The presence of A. pleuronectes and the phylogenetic status of the A. pleuronectes Indonesian haplotype were reported. Clarifying the phylogenetic status of ecologically important species provides basic information for biosecurity studies for possible future conservation and control programs.

Published: October 2023

Coral reefs are one of the ecosystems that provide economic and environmental benefits to coastal communities in Indonesia. However, coral reef ecosystems are also one of the ecosystems threatened by climate change at the local scale. The waters of North Sekotong, West Lombok, Indonesia, are a tropical coastal system with beautiful coral reefs and marine ecosystems. Coral reef damage has been widespread in this area due to increased water temperatures. Increased water temperature results in coral reef degradation. Field surveys were conducted on May 23-28, 2016, in collaboration with the Marine and Coastal Resources Research and Development Center, Ministry of Marine Affairs and Fisheries, and coral reef mapping using Landsat 7 and Landsat 8 during 2002 - 2016 as well as processing monthly sea surface temperature (SST) data from the AquaModis and Oi SST V2 satellites and daily SST data from the NOAA Coral Reef Watch satellite. Changes in coral cover area were compared with temperature changes due to climate change. The increase in temperature creates a hotspot phenomenon in the coral reef ecosystem, resulting in coral reef degradation. The results showed that coral reefs in this area have degraded by 17.55% or 78.21 Ha from 455.68 Ha (2002) to 367.46 Ha (2016), with a degradation rate of 2.8 Ha/year in 2002 - 2014; 8.1 Ha/year (2014 - 2014) and 36 Ha/year (2015 - 2016) caused by an increase in SST which caused a hotspot phenomenon with a high enough intensity that there was an increase in temperature in 2016 which reached 9.77oC.

Published: October 2023

The availability and quality of fry is a major problem in blue swimming crab aquaculture, with the high mortality at the larval stage. RNA/DNA ratio is one of the parameters that can be used to evaluate the quality of crab fry, including health, nutrition, and growth conditions. This study aims to analyze the effect of Phronima sp. as a substitute feed for Artemia salina on the RNA/DNA ratio performance of blue swimming crab in juvenile phase (crablet 5) during rearing before cultivation in aquaculture ponds. This research was conducted at the Crab Hatchery Unit of the Brackish Water Aquaculture Fisheries Center (BPBAP) Takalar in February 2023. The study used a quantitative experimental completely randomized design (CRD) with five treatments and three repetitions. The ratio of Phronima sp. and Artemia sp. used were: Treatment A 100% Phronima sp; Treatment B 100% Artemia sp; Treatment C 75% Phronima sp and 25% Artemia sp; Treatment D 25% Phronima sp and 75% Artemia sp.;  and E: Phronima 75%+Artemia salina 25%. The results showed that Artemia salina combined with Phronima sp. increased the RNA/DNA ratio of the crab compared to a single feed (100% Phronima sp. or Artemia salina 100%). The feed combination with the highest RNA/DNA ratio was shown in treatment E (Phronima sp. 25% + Artemia salina 75%) with an RNA/DNA ratio of 2.02 +0.032 ng/µL.
Coding splits in the adnominal possessive construction and alienability: the case of Mandinka (West Mande)
Authors: Creissels Denis
Published: October 2023

In the adnominal possessive construction of Mandinka (a West Mande language spoken in Gambia, Senegal, and Guinea Bissau), the possessor NP may be simply juxtaposed to the possessee or flagged by the postposition lá. This coding split shows unusual properties in comparison with most of the languages having formally similar coding splits. Crucially, any noun can be modified by an unflagged possessor, depending on the semantic nature of the possessor and of its relation to the possessee. The present-day distribution of the two constructions cannot be analyzed as reflecting an alienability contrast, nor can the alienability contrast account for the emergence of this coding split. The data analyzed in this study suggest that the lá-construction initially referred to situations where the possessor determines the location of the possessee, but is grammaticalized differently depending on the grammatical nature of the head noun and the semantic nature of the modifier. The Mandinka data also show the limits of explanations in terms of discourse frequency, and the need to admit that semantic features such as animacy and control may play a crucial role in the genesis of coding splits in the adnominal possession construction.

Published: October 2023

Abstract. The article is devoted to the analysis of the features of various distributed generation systems from the point of view of their inclusion in a single distributed energy system. It is shown that the need to switch to distributed generation is associated with the need to create reliable power supply systems that can maintain their performance in the event of partial or complete destruction of any part of such a system. The devices of solar, wind and hydropower, as well as the possibility of using small modular nuclear reactors as devices for distributed generation are analyzed. It is shown that the most promising for application are environmentally friendly solar cells. Wind generation and small hydropower plants can also be used to create sustainable and reliable power supply systems. Small modular reactors can be used to power large cities and industrial consumers. The analysis of economic and energy parameters of various devices of distributed generation is carried out. It is concluded that the elements of a distributed generation system can be not only individual devices, but also systems of such devices at the level of a territorial region. Keywords: distributed generation; electrical system; solar energy; solar power plants, wind energy; modular nuclear reactors; intelligent networks.
Climate and weather-related factors limiting outdoor activities and impacting tourism: Case studies in Slovenia
Authors: Mikoš Matjaž , Golja Aleš , Bezak Nejc
Published: October 2023

Tourism must adapt to climate change while doing its part to help fulfil the Sustainable Development Goals. In scientific literature, climate services for tourism are under-researched. Slovenia (Central Europe), with its diverse climate and topography, was chosen as a case study to investigate climate change’s effects on the country as a tourist destination. Using publicly available meteorological data, the Tourism Climate Index and the Holiday Climate Index were estimated. The two indices show a weak relation to the statistical data on overnight stays in selected municipalities for the period 2019-2021. The climate change impact on ski tourism in nine ski areas in Slovenia was estimated using statistically significant negative trends of annual number of days with snow cover. The negative trends were more pronounced for the period 1961-1990 over 1991-2020; 1987 was determined as a turning point in the trend detection. Typical outdoor activities on the Soča River in western Slovenia include rafting and canoe rafting. The trends in river discharges were used to estimate the impact of climate change on the number of navigable days per year and per season (March 15 – October 31), and no clear trends were found in this case study. Further investigations are needed to support tourism adaptation strategies and investigate climate-tourism interaction.

The article analyses the literature on the dependence of mechanical properties (tensile strength, hardness, etc.) of grey cast iron castings on the percentage of chemical elements in its composition and on the carbon equivalent, degree of eutecticity, and the ratio of carbon to silicon content. On the example of assessing the mechanical properties of cast iron with lamellar graphite, these dependencies are considered in the probabilistic aspect. It is emphasised that even within the same ranges of percentage of chemical elements in cast iron, as defined in standards or specifications, the values of its carbon equivalent, eutecticity, and the ratio of carbon to silicon content may be different. On the other hand, with different percentage ratios of chemical elements in the cast iron composition, the values of its carbon equivalent may be the same. It is shown that the conclusion about the presence or absence of correlation, in particular, between the hardness of castings and the carbon equivalent of the grey cast iron from which they are made, depends on the interval of variation of this argument. If the variation in the hardness of castings is significant and the interval for changing its carbon equivalent, calculated according to the chemical composition of cast iron specified in the standard for a particular casting product, is relatively short, the dependence of cast iron hardness on its carbon equivalent may not be evident. The disadvantage of the known empirical formulas intended for the approximate calculation of the tensile strength and hardness of cast iron based on its carbon element and eutecticity is the uncertainty of the choice of these indicators. It is proposed to use in such formulas the mathematical expectations (average values) of the carbon equivalent, eutecticity degree and the ratio of carbon to silicon content determined in the probabilistic approach using the Monte Carlo method. It is recommended that the distributions of chemical elements in grey cast iron within their intervals provided for in the standards be considered in accordance with the normal Gaussian law. Based on the information on the chemical composition and properties of grey cast iron with lamellar graphite smelted in accordance with the requirements of DSTU 8833-2019, the dependence of the carbon equivalent and the degree of eutecticity on the ratio of carbon to silicon content, as well as the strength and hardness of castings on these characteristics of the chemical composition of cast iron, have been identified. The formulas for determining the mechanical properties of grey cast iron with lamellar graphite have been calculated. Keywords: cast iron, casting, chemical composition, carbon equivalent, carbon to silicon ratio, degree of eutecticity, hardness, strength.

The analysis of the world market of iron and iron castings in 2002-2022 is presented. During the period from 2002 to 2022, the production of iron in the world grew at an average annual rate from 5.7 to 1.3%. An increase in the domestic consumption of iron by the producing countries was noted. The main consumers of cast iron are steel and cast iron production. The volumes of production, export, import, and consumption of cast iron compared to world GDP in 2002, 2012, and 2022 are shown. The top ten producers of cast iron in 2018 and 2022 are presented. Ukraine occupies the 12th position. A comparison of the dynamics of the production of iron and cast iron shows that during 2002-2021, the average annual growth rate of production of cast iron in the world was 4.0%, and that of cast iron was 2.0%. The ratings of the world manufacturers of iron castings in 2018 and 2021 were considered. The production of iron castings in the world is characterized by both increasing (2002-2011) and stable production (2012-2021). Today, cast iron remains the most widely used casting material. The main reasons for the long-lasting dominance of cast iron in a wide range of products are related to its mechanical and physical properties and its competitive price. If all ferrous alloys in the global foundry production make up more than 80%, then we are living in the Iron Age. The review provides two examples from the "cast iron world" that describe the development of centrifugal casting of high-strength cast iron pillars with lengths from 9 to 30 m and with a casting cycle time of up to 12 minutes for a base pillar. Such utility poles weigh less than wooden poles and are much lighter than concrete poles, have high fire resistance, withstand significant wind loads and have a service life of more than 75 years, surpassing both steel and wood. It was also noted that cast iron is actively used for the production of household utensils, with a projected increase in its output. Keywords: market, cast iron, cast iron castings, trends, production.
Market status of the energy, produced from animal biomass and prospects for development in Bulgaria
Authors: Georgieva Nely , Tsankov Petko , Hristov Vasil , Kirov Kalin
Published: October 2023

Bulgaria has long fulfilled its commitments to the use of renewable energy sources (RES) in the national energy mix, with the Eurostat data for 2020 showing a share of 23.3%, while the EU average is 22.1%. This places us third in terms of achieving the national energy targets for this indicator for 2020. However, if we analyze the data provided, we will find that this is mainly due to the installed photovoltaic and wind installations. Energy production from biomass ranks only fourth in the national mix, with a much smaller share compared to the potential that Bulgaria has.
The aim of this study is to identify the problems for wider use of animal biomass waste for biogas production in Bulgaria by analyzing the current regulatory framework and incentives provided for the development of biogas technologies, as well as analyzing the existing infrastructure of operating biogas plants in Bulgaria.
Retinalis artéria macroaneurysmák diagnosztikai és kezelési lehetőségei eseteink kapcsán

Közleményünkben négy, szövődményes retinalis artéria macroaneurysmával
diagnosztizált beteg kórtörténetét mutatjuk be. Célunk a betegség változatos
megjelenésének bemutatása és a különböző terápiás lehetőségek ismertetése. A
retinalis artéria macroaneurysma ritka, de potenciálisan látásvesztést okozó
szemészeti kórkép. Kialakulásának hátterében a retinalis artériának a magas
vérnyomás okozta arterioscleroticus átalakulása áll. A macroaneurysmák lehetnek
aszimptomatikusak, illetve társulhatnak látásromlást okozó exsudativ vagy
haemorrhagiás szövődménnyel. Kezelésük a tünetektől függően történhet lézeres
fotokoagulációval, intravitrealis injekciókkal, illetve vitrectomiával.
Bemutatott eseteink is szemléltetik, hogy minden eset egyedi mérlegelést
igényel, mert az egységes terápiás ajánlás még kidolgozásra vár. A szemészeti
kezelés mellett kiemelkedően fontos a beteg belgyógyászati gondozásba vétele.

Bevezetés: A koronavírus-világjárvány jelentős terhet rótt az
intenzív terápiás osztályokra, és rávilágított az ellátást végző szakemberek
hiányára. A megnövekedett munkaterhek és a magas halálozási arány miatt az
intenzív ellátásban dolgozókat a korábbinál nagyobb fizikai és pszichés stressz
érte a pandémia alatt. Célkitűzés: Kutatásunk célja volt annak
vizsgálata, hogy a koronavírus-járvány milyen hatást gyakorolt az intenzív
ellátásban dolgozók érzelmi, mentális és morális állapotára.
Módszer: Munkacsoportunk a Semmelweis Egyetem
Aneszteziológiai és Intenzív Terápiás Klinikájának dolgozói körében végzett
papíralapú kérdőíves vizsgálatokat. Első felmérésünk a világjárvány kezdetekor,
2020-ban, a második a harmadik járványhullám után, 2021-ben történt. Validált
kérdőíveket alkalmaztunk (Szakmai Életminőség Skála, Demoralizációs Skála,
Észlelt Stressz Kérdőív, Események Hatása Kérdőív és Poszttraumás Növekedés
Kérdőív), és a demográfiai adatokon túl az életmódról, a szabadidős
tevékenységről, a táplálkozási szokásokról és a pszichés támogatás elfogadásáról
gyűjtöttünk információkat. Eredmények: A két vizsgálat
résztvevőinek létszáma és demográfiai összetétele eltér, tükrözve a személyi
állománynak a járvány idejét jellemző változását. Az egyes dolgozói és a
szociodemográfiai csoportok között a pandémia előtt nem mutatkozott különbség,
ám egy évvel később az ápolók minden negatív skálán szignifikánsan magasabb
pontszámot értek el a többi csoporthoz képest. Kevesen vettek igénybe
pszichológiai segítséget a vizsgált időszakokban (9,5–12,7%), ugyanakkor
pszichológiai támogatás iránti igényt a válaszadók harmada megfogalmazta. Az új
munkakörben dolgozók szignifikánsan nagyobb mértékű poszttraumás növekedést
(2,91 ± 0,82 vs. 2,20 ± 1,06, p = 0,016) mutattak.
Megbeszélés: Eredményeink alapján az ápolók képezik a
leginkább leterhelt dolgozói csoportot egy bizonytalan és stresszes időszakban.
A pandémia alatt rendelkezésre álló pszichés támogatás önmagában nem bizonyult
elégségesnek. Következtetés: A dolgozók mentális egészségének
javításához további lépések szükségesek. Orv Hetil. 2023; 164(42):

Published: October 2023

A mono-, majd duális hormon(inkretin)receptor-agonisták terápiába állítását
követően a 2-es típusú diabetes és az elhízás gyógyszeres kezelésének egyik új
lehetőségeként a hármashormonreceptor-stimulálás, a glükagonreceptor kiegészítő
aktiválása felé fordult a figyelem. A dolgozat a szénhidrát-anyagcserében
betöltött szerepe mellett áttekinti a glükagon további élettani feladatait,
kiemelten az intrainsularis parakrin szabályozásban, az energiaforgalomban és az
étvágy befolyásolásában való részvételét. Kitér a hármas kombináció lehetséges
előnyeire, és röviden érinti az első hármashormonreceptor-agonistával, a
retatrutiddal kapcsolatos preklinikai humán vizsgálatok hatékonysággal és
biztonságossággal kapcsolatos adataira is. A biztató eredmények további
megerősítése előrelépést jelenthet e kórformák és kísérő állapotaik – így a
steatosis hepatis − kezelésében. Orv Hetil. 2023; 164(42): 1656–1664.
