The object of this study is the production costs of ecologically oriented innovative products.
The problem under consideration was to improve the efficiency of cost management for the production of eco-innovative products by improving the methodical approach to identifying reserves for their reduction in order to ensure competitive advantages and strengthen the economic and environmental security of the enterprise.
The devised methodological approach is based on a systematic analysis using economic and mathematical methods. It provides for the establishment of the dependence of costs per dollar of eco-innovative products on factors related to the economic potential of the enterprise, and the search for reserves for reducing costs for the production of eco-innovative products.
The analysis technology was substantiated and modeling of costs per dollar of eco-innovative products of the enterprise was carried out using the principal component analysis. A distinctive feature of the built model was the consideration of the influence of micro-level factors, risk management, and the innovative component of the enterprise's economic potential. The resulting model is significant and reliable since the variation of costs per dollar of innovative products depends on the change in the principal components under investigation by 85 %.
Within the framework of the devised methodical approach, a technology for calculating reserves for reducing production costs of enterprises producing eco-innovative products has been proposed. It was established that the potential of reducing costs per dollar of eco-innovative products for the totality of the investigated enterprises is on average 5.4 cents per dollar of costs.
The area of practical use of the devised methodical approach is the process of minimizing and optimizing costs per hryvnia of eco-innovative products

Published: August 2024

The object of research is the physical processes of electric energy storage in Li-ion batteries. The problem being solved in the work is related to the lack of reliable mathematical models of storage batteries, which leads to the appearance of undesirable effects or emergency situations when changing operating modes.
In the course of the work, Li-ion battery models based on electrochemical theory and electrical circuits were considered. The six most common equivalent battery replacement schemes are presented. The advantages and disadvantages of the considered substitution schemes are given. The dual-polarization mathematical model was found to most accurately describe the performance of the battery at the end of the discharge and charge cycles compared to the first-order Thevenin model, the RC model, and the active resistance battery model. The physical processes in the storage battery during pulse discharge, which is the main part of electrical energy storage systems based on electrochemical technology, were studied. Mathematical modeling was carried out in the Matlab software package using the Simulink application program package. The dependence of the parameters of the equivalent lithium-ion battery replacement scheme according to the second-order Thevenin model on the ambient temperature and state of charge is considered. It was established that the value of EMF E depends more on the change in SOC than on temperature. In turn, the active resistance ROM shows a greater dependence on temperature than on the change in SOC. At high temperatures, the resistance value decreases. The parameters R1 and C1 characterizing the electrochemical polarization vary in the range from 10 to 75 % SOC. The parameters R2 and C2, which depend on the concentration polarization, vary in the intervals from 0 to 25 % SOC and 75 to 100 % SOC.
The recommendations for choosing a Li-ion battery model developed in the work can be used in practice. The established dependencies will help to better design electrical energy storage systems based on electrochemical technology.

The object of the study is the phosphates of the Djebel Onk region, which are part of a vast group of phosphate deposits formed in the Late Cretaceous-Eocene period on the South and Southeast Mediterranean shores. These concentrations of economic interest are operated near the town of Bir El Ater (Tebessa, Algeria). The mining industry based on the extraction and processing of different minerals while respecting the environmental framework plays an important role in the economy of a country. The economic potential of each country will be determined based on the level of production of metals and various mineral substances. In the case of the Djebel Onk phosphate ore, the most dominant mineral in addition to P2O5 is calcium carbonate CaCO3 with more than 50 % in the all-mineral content. In addition, phosphate concentrate contains harmful elements which reduce the value of the market product. Therefore, this study aims to recover the enriched product efficiently and profitably with a minimum of deleterious elements. This work aims to develop a treatment technology with a minimum rejection rate, which allows for achieving production goals and reducing environmental impacts. For this purpose, we proposed an enrichment of these phosphate discharges from the settling process utilizing pneumatic selection (Turbo Separator Ventilate – TSV). The results of the chemical analyses confirm the significant difference in useful and major elements (P2O5) and the minor and harmful elements (MgO). According to the granulochemical analysis of each slice, it is possible to note that the P2O5 content is similar to the various particle-size slices. It is therefore necessary to treat the mass of waste if we want to recover as much phosphate as possible. The obtained X-ray diffractograms highlighted appreciable differences between the raw phosphates and the concentrates, in fact, the qualitative and quantitative variation of the mineralogical species, particularly the calcite, quartz, dolomite, and apatite. TSV is a process used to improve the quality and quantity of phosphate and to eliminate the layer below 0.8 mm. Corresponding to the analyses it was appeared that the P2O5 content 29.5–30 % of the settled product increases to 30.2–31 % after dust removal. Then it is possible to achieve an increase in the quality of phosphate from 63/65 % TPL to 66/68 % TPL.

Published: August 2024

The object of research is the quality indicators of sugar enriched with derivatives of the processing of the fruits of wild plants (viburnum, mountain ash, sea buckthorn, black elder) and potential dangerous factors that may arise during its production. This study is aimed at the analysis and assessment of all risks that arise in the production of sugar enriched with derivatives of processing of wild raw materials. For the production of enriched sugar, pre-cleaned fruits were frozen at a temperature of –18±2 °С, and after defrosting, they were partially dehydrated by the method of osmotic dehydration. For this, a 70 % sugar solution with a temperature of 50±5 °C was used (hydromodule 1). The duration of osmotic dehydration was 1 hour. The derivative product formed as a result of osmotic dehydration of fruits (sugar solution) was used to enrich granulated sugar in the amount of 10 % by mass of sugar. After thorough mixing with the solution, the sugar was dried in a laboratory vacuum dryer and analyzed. Based on the principles of HACCP, a detailed description of the product and its use with a specific purpose has been developed. In particular, the description of all stages of production, from the initial materials to the processing and packaging processes, as well as the definition of all possible dangerous factors that can affect the safety and quality of products. The identification and assessment of all hazardous factors included the analysis of all possible threats to the safety and quality of products at each stage of production. To ensure the quality and safety of enriched sugar obtained from wild raw materials, an assessment of potential dangerous factors at all stages of production was carried out. A HACCP plan has been developed that allows effective management of critical control points and evaluation of the results of this management. This will allow potential manufacturers to produce safe and competitive products of high quality. The practical implementation of these proposals will allow bringing new products to the market - elderberry, sea buckthorn, rowan and viburnum sugar.

This paper provides an overview of the solid waste management market, which is the object of the study, including the processes of collection, transportation, utilization and recycling, supervision and monitoring of these processes. The volume and dynamics of the global waste management market in 2023 and its forecasting until 2033 are considered. The problem solved in the article is to identify the key factors of influence and interconnection on the development of waste management market components to determine the directions of an effective sustainable development policy. The author analyzes the methods of waste management in different European countries and identifies the key factors influencing the market dynamics: the effects of urbanization, environmental regulations, waste-to-energy technologies, circular economy initiatives, smart waste management systems, increased waste recycling, and the development of green infrastructure. It is determined that the growing awareness of environmental problems and increasing public pressure are leading to an increase in government investment in the development of innovative technologies for effective waste management.  It is established that the promotion of recycling infrastructure and the implementation of campaigns aimed at raising awareness among the population leads to an increase in the importance of responsible waste management, the introduction of public-private partnerships in the field of waste management and the development of green infrastructure. The market is analyzed by region, end user, and waste type. According to the regional analysis, North America has the largest market share, but Asia Pacific is showing the fastest growth. North America has a large waste management market due to its developed infrastructure and high level of environmental awareness. However, Asia-Pacific, particularly China and India, is emerging as a growth center due to rapid economic development, population growth, and rapid urbanization, indicating the potential for new waste management markets in this region. According to the analysis by waste type, industrial waste is the largest category, with the electronic segment showing dynamic growth. This analysis allows to forecast the market and trends in the waste management industry, which makes it possible to calculate costs and profits, scale global trends to Ukrainian realities, and offer promising investment opportunities, which is especially important in the times of recovery of Ukraine.

Published: August 2024

The object of research is the process of frying a meat-vegetable product in the developed universal low-temperature rotary apparatus. The problem of ensuring the uniformity of the temperature field during low-temperature processing of meat and vegetable products is solved in the developed universal low-temperature rotary apparatus. The expected effect during the approbation of the apparatus is predicted under the condition of eliminating high-temperature intermediate coolants (hot air, etc.) due to the use of a film-like resistive electronic heater of the radiating type. The temperature field is established, which confirms the uniformity of the temperature effect on meat and vegetable products, and a slight deviation within the limits of autonomous exhaust fans is not critical and within the permissible error. Also, the introduction of Peltier elements into the design of the rotary apparatus will allow converting thermal energy into a low-voltage supply voltage (3–6 W) and, already at 20 °C, ensure autonomous operation of fans. The obtained results in the form of practical implementation of the developed apparatus will allow to implement low-temperature processing of meat and vegetable products. This allows to maximally preserve the functional properties of meat raw materials and the physiological properties of vegetable semi-finished products with a high degree of readiness.
The practical implementation of the universal low-temperature rotary apparatus from the side of constructive implementation due to the use of functional containers makes it possible to obtain a wide range of assortment of meat products, both in the shell and without the shell. The elimination of high-temperature intermediate heat carriers (hot air, steam, etc.), their technical networks and generating apparatuss ensures energy and metal-intensive resource savings. In addition, the introduction of multicomponent vegetable semi-finished products of a high degree of readiness (powders, pastes, etc.) into the recipes of meat products will lead to a partial replacement of the main recipe components and an increase in the functional properties of the finished products.

Authors: Sriharyani Yuni
Published: August 2024

This study examines the populist rhetoric of political actor, Muhaimin Iskandar, delivered on @CakIminNow during the 2024 Indonesian presidential election campaign, especially in the tweet dated October 1, 2023 regarding the Celebration of Pancasila Sanctity Day. This study uses a critical paradigm and Roland Barthes' semiotic analysis technique in analyzing nine units of analysis posted on @CakIminNow. The results of this study have revealed that the representation of moderate Islam has been utilized as a tool of populist rhetoric by Muhaimin Iskandar (Cak Imin) as one of the vice presidential candidates in the 2024 election. In addition, moderate Islam is not only seen as a system of beliefs and religious practices but also as a commodity in political marketing communication efforts by political actors. In short, this populist rhetoric functions as a strategy to strengthen the political image and garner voter support during Indonesia’s 2024 presidential election campaign.

In this study, a performance of the complex oxide composition of Pr0.4Sr0.6Co0.2Fe0.7Nb0.1O3–δ was investigated from the viewpoint of its use as a fuel or symmetrical electrode for the electrochemical devices with a LaGaO3-based solid electrolyte. The results show that the above-mentioned oxide can be obtained as a single-phase composition using solid-phase synthesis with a final annealing temperature of 1150 °C. It has been shown that the oxide retains satisfactory stability at 800 °C in an atmosphere of 5 % H2 + Ar, only a minor amount, presumably of Co-Fe alloy, has been detected. The electrical conductivity of the oxide in wet hydrogen exhibits a linear semiconductor-type behavior with a conductivity value of 7 S · cm–1 at 800 °C. The polarization resistance of the Pr0.4Sr0.6Co0.2Fe0.7Nb0.1O3–δ electrode in wet hydrogen atmosphere reaches approximately 1.09 Ω · cm2 at 800 °C, which is a relatively high value for the electrodes of electrochemical devices. A significant reduction in resistance down to 0.43 Ω · cm2 is observed for the electrode activated with impregnated ceria. It has been demonstrated that the observed decrease in resistance is due to the expansion of the area of the electrochemical reaction without changing its mechanism. The long-term tests with a duration of about 220 h at 800 °C in a wet hydrogen atmosphere demonstrate satisfactory stability of the electrochemical activity of the Pr0.4Sr0.6Co0.2Fe0.7Nb0.1O3–δ electrode, which can be considered as a promising electrode for intermediate temperature electrochemical devices, including those of symmetrical design.

Published: August 2024

Glutathione (GSH) is a tripeptide composed of three amino acids: cysteine, glycine, and glutamate. It is essential to many different living things as an antioxidant. GSH serves as a key biomarker and its detection is crucial for studying its levels in living bodies, providing insights into various diseases. In this work, we present the use of a highly sensitive electrochemical sensor to detect GSH utilizing a graphene oxide (GO)–modified indium tin oxide (ITO) electrode immobilized with the enzyme horseradish peroxidase (HRP). The modified electrode was further characterized by Fourier transform infrared spectroscopy, and the spectrum showed that HRP was successfully immobilized onto GO. The electrochemical behavior of the modified ITO was examined by cyclic voltammetry. Cyclic voltammetry demonstrated HRP/GO/ITO electrode has better electrocatalytic activity than bare ITO in the oxidation of GSH in acetate buffer solution. The electrochemical sensor had a 1 µM detection limit and a linear range of 10 to 50 µM. The HRP/GO/ITO electrode resulted in improved electrocatalytic properties, long-term stability, good repeatability, and high sensitivity, and it has a quick response to detect GSH. In addition, GSH concentration in real sample was measured using the HRP/GO/ITO-modified electrode.

Published: August 2024

In this study, a plasma frequency selective surface (PFSS) was designed with an array of ordinary fluorescent lamps backed by a conducting plate. The proposed PFSS structure was used as a reflector with the spiral two arms Archimedean type Global Navigation Satellite System (GNSS) antenna to reduce the overall size of the antenna system. Characteristics and the performance of the proposed system were presented by using the results of simulations and experiments in the GNSS band. The optimum distance between antenna and PFSS was found to be around 35 mm to achieve a maximum gain in the simulation which is a lower profile than antenna with conventional conductive plate (66 mm at the GNSS center frequency). Experimental results show that the antenna system has mean values of around 6.7 dBiC gain, 1.27 dB axial ratio and less than -10 dB return loss in the range of 1.14 and 1.61 GHz. All these results show that the proposed novel antenna system is suitable for the reception of the GNSS signals with the advantage of its low profile design.
Characterization of Micro-seismic Activity in Northern Cyprus Using Complexity and Corner Frequency Methods
Authors: Yavuz Evrim
Published: August 2024

Cyprus is an island country located in the eastern Mediterranean, to the south of Türkiye and the western of Syria and Lebanon, and is a popular tourist destination. Due to being surrounded by seas on all four sides, meticulous planning of rescue, assistance, and evacuation plans is necessary in the face of disasters such as earthquakes and tsunamis. Tectonically, the southern part of the island is controlled by the Cyprus Arc, while the northern part is dominated by the Kyrenia Range. The demand for raw materials for construction and industry is met through controlled quarry blasting operations carried out by open-pit quarry companies in the districts of Kyrenia and Nicosia. As a result, both natural and artificial seismic events occur in the region, and these quakes are documented in seismic catalogs by seismology centers. However, due to the low energy content of micro-seismic events and the inadequacy of seismic stations on the island, the source types of these seismic events can be misidentified in the catalogs. In this context, the study focuses on 122 seismic events with magnitudes between 0.9≤Ml≤2.7 that occurred in Northern Cyprus during the January 2018 - December 2021 period (4 years). The seismic events recorded by the station LFK, operated by Boğaziçi University Kandilli Observatory and Earthquake Research Institute Regional Earthquake-Tsunami Monitoring Center (KOERI-RETMC), were classified using Linear and Quadratic Discriminant Functions based on complexity and corner frequency methods. According to the results obtained, 10 of the 122 seismic events were identified as natural, and 96 were determined to be artificial, resulting in a general success rate of 86.89%. However, classification results for 16 seismic events were inconclusive with the methods used. As a result, more detailed secondary analyses should be conducted to accurately determine the source types of micro-seismic events, and the seismic catalogs should be updated accordingly.

Authors: Canbolat Fadime
Published: August 2024

In the study, the levels of Cd, Pb, As, and Hg elemental impurities potentially present in coffee bean samples from Indonesia, Kenya, Colombia, Guatemala, and Türkiye were determined using chromatographic analysis, and the analysis results were utilized to assess the risks on human health. The risk assessment of coffee was calculated for one or three servings per day for 365 days a year. Exposure to coffee consumption was calculated according to age groups of young adults and middle-aged adults (20-65 years). When Cd, Pb, As and Hg levels in coffee samples were analyzed, Cd in coffee samples was found to be in the range of approximately 3.70 - 5.89 µg/kg, Pb in the range of 25.68-41.11 µg/kg, As in the range of 1.45-6.64 µg/kg and Hg in the range of 1.06-5.06 µg/kg. Hazard Index (HI) values for all elements in the assessment of non-carcinogenic risks were found to be <1.0. When the cancer risk (CR) value was calculated for Cd, Pb, and As, it was found that the CR value did not exceed the United States Environmental Protection Agency (USEPA) criteria in all coffee samples in both scenarios. Considering the assessment of the health risks of elemental impurities in five different coffee bean samples, it was concluded that all samples' CR and HI values did not exceed the USEPA criteria.

Published: August 2024

As minorias sexuais e de gênero sofrem de estigma e preconceito. Mulheres que não se enquadram nos padrões normativos da sociedade experimentam grandes níveis de estresse e podem ter mais prejuízos na saúde mental. O suporte de uma rede de apoio pode ser fundamental no enfrentamento dessas vivências. Este estudo buscou avaliar se existem relações entre apoio social, estresse de minoria e indicadores de ansiedade e depressão em mulheres lésbicas e bissexuais brasileiras. Trata-se de um estudo de delineamento quantitativo, correlacional e transversal. Participaram desta pesquisa 53 mulheres cisgênero, brasileiras e residentes do Brasil, com idades entre 18 e 50 anos. As participantes responderam ao questionário sociodemográfico, Escala de Apoio Social, Protocolo de Avaliação do Estresse de Minoria em Lésbicas, Gays e Bissexuais– Versão feminina e a Escala de Ansiedade, Depressão e Estresse. Os resultados indicaram que existe uma correlação entre os indicadores de apoio social e do indicador de revelação da sexualidade do protocolo de avaliação do estresse de minoria. Levando em consideração os achados, fortalecer a rede de apoio pode possibilitar uma revelação da identidade sexual de uma forma menos violenta, espontânea e com acolhimento, servindo de apoio no enfrentamento em situações de preconceito.

Authors: Villaseñor José Luis , Ortiz-Bermúdez Enrique , Murguía-Romero Miguel
Published: August 2024

Background: Endemism can originate from multiple biogeographic and evolutionary processes that promote the formation or persistence of species with restricted distributions (rare species). Understanding rare species’ distributions is a central question in biogeography and is crucial for biodiversity conservation.
Questions: What are the rarest plant species in Mexico? How are they distributed? Under what risk categories should they be classified?
Studied species: Vascular species considered rare in the flora of Mexico.
Study site: Mexico.
Methods: “Rare species” were defined as species endemic to Mexico whose distribution is restricted to a single 1 × 1° cell. We analyzed rare species’ distributions and proposed the risk category for each according to IUCN criteria. For some of the species distributed in the cell with the highest number of rare species, we compared the proposed category with published evaluations.
Results: We identified 2,705 rare species. The richest cells in terms of rare species are in southern Mexico. Only 302 species had been previously evaluated under IUCN criteria. The remaining 2,403 qualify for the Near Threatened (NT) category or higher. The cell with the highest rare species richness, located in the Sierra Norte of Oaxaca, contained only 10 species with an existing IUCN risk category; for another 81 species, the categories of Vulnerable (VU), Endangered (EN) or Critically Endangered (CR) are indicated.
Conclusions: Recognizing the rarity of these 2,705 species will increase attention on them, allowing more precise appraisal of their extinction risk and possible strategies for their conservation.

Authors: Nayak Namitha , Mehrotra Sandhya , Mehrotra Rajesh
Published: August 2024

Protoplast transfection is routinely used to study the sub-cellular localization of fluorescent-tagged proteins. Using N. benthamiana protoplasts is advantageous as it is a hardy plant that grows well, especially in tropical climates. Isolating protoplasts from the leaves of young 3-4-week-old N. benthamiana plants compensates for the benefits of using the ephemeral Arabidopsis. Moreover, the larger protoplast size of N. benthamiana offers better visualization of fluorescent proteins at lower magnifications. The protocol described here is an easy method for N. benthamiana protoplast isolation and transfection with simple and economical modifications to increase yield and transfection efficiency. The protocol is optimized for easy performance with minimal laboratory equipment.
Un enfoque transformador de la salud global. Reseña

Published: August 2024

¿Se puede escribir un buen libro académico cuando se percibe que la rabia es lo que ha llevado al autor a escribir el libro? Esta es una pregunta que surge al leer el libro “Repensar la salud global. Marcos de poder”[1], pues la autora habla explícitamente de cómo comenzó su rabia hacia la inequidad (p. 72) y de cómo de alguna manera todavía sigue teniendo esta rabia (p. 93). La respuesta a dicha pregunta la podrá tener el lector al finalizar el libro, después de leer relatos como este durante la epidemia del cólera en Haití hablando de personas siendo atendidas en tiendas de campaña al aire libre: “Se hicieron agujeros en la base de los colchones para que el signo revelador del cólera, la diarrea constante e implacable, pudiera manejarse más fácilmente sin tener que trasladar a los pacientes” (p. 79). Lo cierto es que la doctora Rochelle Burgess dice que escribió este libro con la esperanza de llevar al lector en un viaje para iluminar la complejidad de cómo funcionan las dinámicas de poder en el ámbito de la salud global desde la posición de una psicóloga de salud comunitaria, en cuyo ejercicio profesional encontró su insatisfacción con la salud global.

Can Segmental Branch Embolization of the Left Gastric Artery Be an Alternative in the Treatment of Recurrent Dieulafoy Lesion Bleeding? A Case report
Authors: Sönmez Gamze , İleri Serez , Çay Ferdi , Peynircioğlu Bora , Keskin Onur
Published: August 2024

Dieulafoy lesions, rare developmental vascular malformations within the gastrointestinal system, present a diagnostic challenge due to their inconspicuous nature. These lesions, primarily located near the esophagogastric junction, can lead to life-threatening bleeding. Although accounting for approximately 1.5-2% of upper gastrointestinal bleeding cases, the exact prevalence remains uncertain. Commonly diagnosed through esophagogastroduodenoscopy, the small size of these lesions often results in oversight during initial endoscopy, necessitating a high index of suspicion, especially in cases of recurrent bleeding. While endoscopic methods are the standard treatment, this case presentation introduces the use of embolization as a rare but effective modality in managing recurrent Dieulafoy lesion bleeding. The presented case underscores the importance of diverse treatment approaches and contributes valuable insights to the medical literature, enhancing the understanding and management of this infrequent yet potentially serious condition.

Published: August 2024

The study aims to investigate plant growth promotion (PGP) activities of thermophilic bacteria isolated from the Jakrem hot spring in Meghalaya, North-East India, and determine their effect on Brassica juncea's growth. The bacteria were isolated by a culture-dependent approach following a serial dilution method in a nutrient agar medium. All the isolates were determined for PGP attributes such as indole acetic acid, phosphate solubilization, hydrolytic enzymes, and siderophore production. The potent bacterial isolates were characterized by 16S rDNA sequencing and phylogenetic analysis. Altogether, 53 bacterial isolates were obtained, most belonging to the genus Bacillus. Of the total isolates, 37.7% exhibited both PGP and hydrolytic enzyme activities. Three isolates, namely JAB1, JAB8, and JAB100, showed promising PGP and were identified as Bacillus velezensis, B. proteolyticus, and Bacillus sp., respectively. The PGP attributes of these isolates were determined in vivo on B. juncea, and their effects were measured in terms of shoot and root length biomass and biochemical contents. It was observed that combined inoculation of all three isolates significantly enhanced the growth and development of B. juncea, evident by increased shoot and root length, fresh and dry weight, and higher levels of protein, phenol, flavonoid, and chlorophyll content compared to the control. In conclusion, the study highlights the potential application of thermophilic Bacillus spp. from hot springs as bioinoculants to enhance crop productivity in sustainable agricultural practices.

Authors: Mukilan Murugan , Adithya Rameshbabu , Pruthivi Senthilkumar
Published: August 2024

Probiotics are defined as beneficial microorganisms that are responsible for the maintenance of homeostasis mechanisms within the host system, especially in humans. Other than homeostasis, it is also used to improve a host system's cognition, immune functions, and antioxidant levels. Over the past decades, probiotic microorganisms have been used most commonly as traditional fermented foods in our country and some parts of southeast asia. These fermented food products majorly consist of Lactobacillus species, including Lactobacillus acidophilus, L. fermentum, and L. plantarum. The present study explored the potential role of three different lactobacillus strains (L. acidophilus, L. fermentum, and L. Plantarum) in forming brain plasticity changes (BPC) with the help of a cue-based learning paradigm (CBLP). Two staged behavioral studies were conducted for all behavioral analysis groups (BAG) before (without probiotic infusions - WiPI) and after probiotic infusions (with probiotic infusions - WPI) in RBLP. Behavioral responses of the WiPI & WPI phases showed the effect of a stress-free habituated environment in developing BPC and strengthening of BPC by oral infusions of probiotic microorganisms (PM). WiPI and WPI behavioral analysis were used in this study to validate BPC in a laboratory-controlled environment. Infusion of probiotic microorganisms through oral passage may have a more significant impact on the synthesis, production, and transmission of neurotransmitter precursor compounds (NPC) from the gut to the central nervous system (CNS) through the blood-brain barrier (BBB). Increased transmission of the NPC strengthens the formed plasticity changes, which results in the formation of cognitive memory functions. Thus, the present study proved that probiotic microorganisms may play a major role in cognition development through the BPC.

Understanding the extent of genetic variability within the segregating generations is crucial for identifying superior segregants with high yield and better market acceptability. Thus, the present study was carried out to quantify the extent of genetic variation available in the segregating population of rice. Three crosses, viz., CO 55 × IC 457996, CO 55 × IC 464685, and CO 55 × IC 115439 were evaluated using a non-randomized experimental design for six yield attributing and two physical grain quality traits in F2 generation. The inheritance pattern of basal leaf sheath colour and grain colour in CO 55 × IC 115439 indicate digenic complementary gene interaction (9:7), whereas grain colour in CO 55 × IC 464685 exhibits inhibitory gene action (13:3). The positively skewed nature of productive tillers per plant and single-plant yield in the F2 segregants emphasizes the need for intensive selection to facilitate rapid improvement due to the influence of complementary gene action. Moderate to high GCV with high heritability and GAM for traits such as plant height, productive tillers per plant, hundred seed weight, grain width, and single-plant yield in the F2 segregants underscore the prevalence of additive gene action and thus provide the most effective condition for simple phenotypic selection. Moreover, productive tillers per plant and single-plant yield showed a strong positive association in all the crosses. Therefore, productive tillers per plant can be considered an indicator trait when selecting high-yielding segregants for grain yield improvement.
Unveiling the Dynamic Impact of Queer Celebrities on School Youth’s Perceptions of Gender and Sexual Diversity
Authors: Botha Tercia , Nichols Henry
Published: August 2024

This study explored the disruption of queer celebrities on the normalisation of heterosexuality and cisnormativity amongst school youth.  Qualitative research was employed with a phenomenological research design to conduct semi-structured interviews with seven high school learners between the ages of 16 and 17 in the town of Kroonstad in the Free State Province of South Africa.  The findings highlight the symbiotic relationship between queer celebrities and school youth gravitating between self-identification, challenging stereotypes, visibility, and advocacy.  Bigger platforms for queer celebrities should be created in schools to raise awareness of LGBTQ+ issues and equal rights. This will contribute to a more inclusive society, making its way to educational settings, and leading to more inclusivity of gender and sexual diversity in the school system.

On dating apps, the image that users project of themselves, especially in terms of physical attributes, is important. This study explored how individuals of different generations and genders present their desirability through photos and self-descriptions—‘bios’—on their Tinder profiles. Through a virtual ethnographic study, 400 profiles of users aged 18–70 years were analysed and grouped into generation- and gender-based categories. The photographs were thematically analysed using observation matrices and descriptions. The results showed that, although all groups try to present themselves positively, generation- and gender-based differences exist in how individuals present their physicality through photographs (postures, angles, type of photo, place, facial expressions, body stereotypes, sexualisation) and bios. With respect to generations, these differences are attributable to the values and preferences of each group. Regarding gender differences, the influence of sociocultural stereotypes and ideals of femininity and masculinity is observed.

Objectives: Transposition of the great arteries (TGA) is a rare congenital heart disease that occurs in 3 in 10,000 newborns and is rapidly fatal (90%) within one year if left untreated. The prognosis of this pathology changed after introducing an early arterial switch operation (ASO), while the left ventricle could still adapt to systemic high-pressure conditions. Appropriate regulation of thyroid hormones positively impacts metabolism, cardiac function, and postoperative recovery. Therefore, regular thyroid hormone monitoring and thyroid function monitoring of TGA patients may help to improve the health status and prognosis of this group of postoperative patients.
Methods: In our study, 127 patients who underwent ASO at our pediatric cardiac surgery clinic between 01.01.2014 and 18.09.2021 were retrospectively analyzed and included. Among the patients, 43% (n=54) were females, and 57% (n=73) were males.
Results: The coronary arteries were normal in 89.7% (n=114) and abnormal in 10.3% (n=13) of the patients. Twenty-one of the patients exited, and mortality was calculated to be 16.5%. There were no significant differences in mortality or thyroid stimulating hormone (TSH), free thyroxine (T4), or free triiodothyronine (T3) values (P=0.674, P=0.345, P=0.478). In our study, in which we investigated the effect of thyroid hormone levels on prognosis in neonatal patients with TGA with normal free T3, T4, and TSH values, we found that TSH levels were greater in the group with advanced aortic regurgitation and exitus, although the effect of thyroid hormones on postoperative results was not statistically significant.
Conclusions: Congenital hypothyroidism is a common disease with cardiac effects. During the neonatal period, this disease may conceal itself. Careful, expert clinical follow-up and clinical trials are crucial to improve outcomes in the surgical treatment of transposition of the great arteries, a complex congenital heart disease.

Published: August 2024

Geguritan (Javanese poetry) is a fascinating literary work to study from various perspectives, one of which is from the perspective of ecocriticism. Ecocriticism examines environmentally oriented criticism of literary works. This research examines ecocriticism in the geguritan "Sendhang Tirta Panggesangan," created by S. Wignya Raharja. This type of research is qualitative descriptive research. The data in this research is in the form of sentences in the "Sendhang Tirta Panggesangan" geguritan. The data collection technique used was the literature study technique, which involved studying reference sources from similar articles regarding literary ecocriticism. The data analysis technique used is content analysis, which is carefully reading the geguritan and analyzing it using literary ecocriticism. The results of the research show that there is ecocriticism contained in the "Sendhang Tirta Panggesangan" geguritan in the form of a depiction of the sendhang environment, which has been polluted and is no longer natural as a result of human activities.

Suriye’de yaşanan iç savaş nedeniyle milyonlarca insan başta Türkiye ve Lübnan gibi komşu ülkeler olmak üzere başka ülkelere göç etmek zorunda kalmıştır. Türkiye de sınır komşusu olma, dini, kültürel ve tarihi bağlar nedeniyle Suriyelilerin sığındığı önemli ülkelerden birisi olmuştur. 2022 itibariyle Türkiye’de üç buçuk milyondan fazla Suriyeli geçici koruma altındadır. Göç İdaresi Başkanlığının verilerine göre bunların yaklaşık dörtte biri yükseköğrenim çağındaki gençlerden oluşmaktadır. YÖK bünyesindeki devlet ve vakıf üniversitelerinde öğrenim görmekte olan Suriye uyruklu öğrenci sayısı ise elli üç bin civarındadır. Geçici koruma kapsamındaki üniversite öğrencilerinin yaşadıkları eğitim sorunlarının tespit edilmesi onların eğitimine yönelik politikaların oluşturulması ve uygulanması aşamalarında faydalı olabilecektir. Nitel araştırma yöntemlerinden olgu bilim olarak desenlenen bu çalışmanın amacı geçici koruma altındaki Suriye uyruklu öğretmen adaylarının eğitim ve uyum sorunlarının belirlenmesidir. Bu bağlamda araştırmanın çalışma grubunu Kilis 7 Aralık Üniversitesi Kilisli Muallim Rıfat Eğitim Fakültesinin farklı bölümlerinde okumakta olan yaklaşık 20 Suriyeli öğrenci oluşturmaktadır. Araştırmanın verileri görüşme formu yardımıyla toplanmıştır. Görüşme formunda demografik bilgiler ve katılımcıların yaşadıkları eğitim ve uyum sorunlarını belirlemeye yönelik yarı yapılandırılmış görüşme soruları bulunmaktadır. Araştırmada elde edilen veriler bilgisayar ortamına aktarılmış, Maxqda programı kullanılarak analiz edilmiştir. Veriler içerik analizi yöntemiyle analiz edilmiş ve tümevarım yöntemi kullanılmıştır. Elde edilen verilerden kodlamalar yapılmış, kodlardan kategoriler ve kategorilerden temalar oluşturulmuştur. Çalışma sonucunda Suriyeli öğrencilerin Türkçe seviyelerinden kaynaklı sorunlar yaşadıkları, maddi sıkıntı çektikleri ve bunun eğitim hayatlarını etkilediği, bazılarının iletişim kurmakta zorlandığı ve ayrımcılığa ve ötekileştirmeye maruz kaldığı ve ailesinden destek alamayanların olduğu tespit edilmiştir. Ayrıca büyük kısmının okudukları bölüme aidiyet hissi duyduğu belirlenmiştir.
