This article presents the results of research on the structural-phase regularities and behavior of periclase-spinel refractories under high-gradient thermal loads. The findings from the analysis of structural-phase variability in the refractory samples are used to achieve the desired thermal resistance. Based on the investigation of the subsolidus structure of the MgO–FeO–Al2O3–TiO2 system, predictions were made regarding the characteristics of solid-phase exchange reactions, considering the existence of solid solutions with various types of crystal structures in specific areas of the system. This enabled the application of new principles for ensuring thermal stability in the developed periclase-spinel refractories, specifically through organizing a fragmented, micro-cracked structure by combining solid-phase exchange reactions with the establishment of mobile equilibrium upon reaching stationary-state temperatures. An additional feature is the possibility of phase invertibility of solid spinel solutions, including changes in the type of spinel structure, in particular quandilite. Physicochemical research methods confirmed the enhanced ability of the material to flexibly adapt its phase composition and microstructure to thermal loads. The feasibility of these principles for achieving the structural-phase adaptability of the material to thermal shocks was validated by electron microscopy analysis.

Authors:   Lviv Polytechnic National University, Melnyk S. , Rohovyi Yu. , Melnyk Yu. , Zamula M.
Published: November 2024

The regularities of extraction of adsorbate from spent bleaching earth (SBE) of sunflower oil by the esteraldehyde fraction (EAF) have been established. The content of the substances adsorbed by SBE was 34.1%, including 19.2% free fatty acids (FFA) and 11.1% moisture. The influence of temperature (50 and 700C), extraction duration (60 and 120 min), and the mass ratio of EAF to SBE ((2–4):1) on the extraction parameters has been determined. It was found that increasing these process parameters enhances the extraction degree of the adsorbate and FFA from the bleaching earth, reaching 41.9% and 34.4%, respectively, at a temperature of 700C, extraction duration of 120 min, and a mass excess of EAF to SBC at a ratio of 4:1. Optimal conditions for the removal of FFA from SBE were identified. It was established that strong acidic sites are present on the surface of the bleaching earth, with the acidity of fresh, spent, and EAF-treated bleaching earth being 0.79, 0.77, and 0.74 mmol H+ per gram, respectively. The basicity of fresh bleaching earth was 0.073 mmol OH– per gram, indicating the ability of bleaching earth to catalyze the esterification of FFA with ethanol. The suitability of the obtained extract for the production of FFA ethyl esters was demonstrated.

Authors:   Azerbaijan Technical University, Talybov G.М.
Published: November 2024

A convenient method for the synthesis of propargyl(allyl) aryloxyethers is proposed. It is notable that the synthesized compounds exhibit increased reactivity and are rich in nucleophilic centers. Experimental data have established that these compounds are stable and do not undergo hydrolysis. The yields of the target products in both cases are up to 89.2%. The reaction duration and the volume of substituents at the alkoxy group do not significantly affect the yield of the target products. The composition of the synthesized compounds includes groups of signals from protons of the allyl and propargyl groups. The reactions and purity of the obtained compounds were monitored by thin layer chromatography. The yields of allyl ethers are higher than those of propargyl ethers. Some physicochemical properties of the synthesized compounds are presented, and their composition and structure are confirmed by elemental analysis. All synthesized compounds have been identified by IR and NMR spectroscopy.

Background & Aims Experiencing stigmatization behaviors in children with post-burn deformities can leave lasting negative effects on their mental and social health, and is considered an important issue in the child's growth and development. This research aims to investigate the perceived stigmatization in children with deformities or visible scars caused by burns referred to treatment centers in Tehran, Iran. Materials & Methods In this cross-sectional study, 190 children aged 8-18 years with a history of burns resulted in deformities or visible scars participated. Sampling was done using a convenience method from October 20, 2021, to October 20, 2022. The 21-item perceived stigmatization questionnaire (PSQ) was used to collect information. Data analysis was performed in SPSS software, version 21 using independent T-tests and analysis of variance. Results The mean total score of PSQ was 2.199 ± 0.562. The domain of confusing/staring behaviors had the highest score of 2.517±0.820. Perceived stigmatization showed significant relationships with children’s age (P=0.030), gender (P= 0.010), educational level (P< 0.001), time since burn (P<0.001), and frequency of reconstructive burn surgery (P=0.009). Moreover, perceived stigma in children was significantly correlated with their mothers' education level (P=0.007) and occupation (P=0.003). Conclusion Female children with deformities or visible scars caused by burns tend to experience stigmatization behaviors more frequently than males. These children experience these behaviors mostly during early adolescence. Additionally, a higher number of reconstructive surgeries and a shorter time since the burn accident are linked to high perception of stigmatization in these children. Moreover, children of employed mothers and those whose mothers have higher educational levels report more perceived stigmatization. It is important for nurses to identify these issues and refer the cases who require additional support to available social treatment centers for further assistance.

Authors: Sebti Latifa , Baroudi Faten
Published: November 2024

Arab international students are considered an integral part of American universities bringing cultural and academic perspectives that enrich campus diversity. Grounded in Bronfenbrenner’s (1977) ecological theory of development, we seek to understand the mutual interactions of ecological factors contributing to Arab international students’ campus engagement and academic success in the United States. We used open-ended questionnaires with 18 Arab students to capture their overall lived experiences and conducted semi-structured interviews with five students to get rich insights into their experiences. The findings of this study have revealed the significant role of global and sociopolitical context in shaping Arab international students’ social and academic engagement, identity, and wellbeing. Implications of this study drive the need for a sociopolitical turn in designing a culturally engaging campus environment and enacting critical pedagogy to support diverse students’ engagement and identity development.
Beyond the concrete jungle: The value of urban biodiversity for regional conservation efforts
Authors: Ventura Lior , Diederik Strubbe , Shwartz Assaf
Published: November 2024

Urbanization deletes and degrades natural ecosystems, contributing to the ongoing biodiversity crisis. Yet, on the local scale, well-managed cities can host significant biodiversity, including endemic and threatened species. Understanding the trade-off between local and regional biodiversity outcomes is limited, primarily due to the lack of comprehensive sampling across heterogeneous urban areas and adjacent regions. To address this knowledge gap and assess urban areas' value for conserving the regional species pool, we conducted an extensive bird survey across an urbanized metropolitan area and its surrounding region (>300 km²). The survey included 11 cities, 24 rural settlements, agricultural areas, and natural habitats, employing high-resolution geographic data (e.g., 3D vegetation layer) to examine land cover effects on α- and β-diversity metrics. Our findings reveal that urban avian diversity can surpass adjacent non-urban areas, with urban green spaces among the most species-rich habitats. Most regional bird species did not avoid urban areas, indicating their significant potential for regional conservation, particularly in human-dominated areas. Across the region, avian communities were highly heterogeneous, driven by species turnover rather than loss, highlighting urban biodiversity complexity. However, factors associated with urbanization negatively affected both α- and β-diversity, with synanthropic species most prevalent in urban habitats. Our findings suggest that strategic urban planning, focusing on compact development and accommodating non-synanthropic species in green spaces, can significantly contribute to regional conservation efforts.

Around 36% of the total waste has not been managed properly, including 4K1P waste (paper, wood, cloth, rubber, and plastic), which is flammable and can be made into RDF briquettes using the pyrolysis method and paraffin adhesive which will used three variations of raw materials, namely from organic, inorganic and mixed waste. The quality of the three briquettes was compared based on calorific value, ash content, water content, and PLTU fuel requirements if used as fuel for a 7.5 MW capacity PLTU. The weight of the initial raw material for briquettes is 2 kg which produces 875 grams of paper carbon charcoal, 648 grams of wood, 1.09 kg of plastic, 856 grams of cloth, and 1.16 kg of rubber, resulting in 10 pieces of organic, inorganic and mixed briquettes each. The test results show that inorganic briquettes have the best quality with a calorific value of 8,075.92 cal/g, water content of 1.75%, and ash content of 10.84%, where the calorific value and water content meet SNI-01-6235-2000. The minimum fuel requirement for a PLTU using RDF briquettes is inorganic briquettes, namely 3.05 tonnes/hour with an annual requirement of 26,205.6 tonnes/year. It can be concluded that inorganic briquettes have the best quality and require the least amount of fuel to be used in PLTU.

The use of liquefied petroleum gas (LPG) as household fuel in Indonesia has increased because it has greater heating power and equipment efficiency than other fuels. LPG is flammable and can explode if a leakage occurs and is exposed to a fire source. Therefore, explosions can be anticipated by installing a gas leakage detector equipped with a danger warning feature called Tor-G (LPG Detector) based on the NodeMCU ESP8266 microcontroller using an MQ-2 sensor with a buzzer and LED as a danger warning feature. Tor-G can detect when a gas leakage occurs and provides a danger signal in the form of a sound from a buzzer which can be heard several meters away by the homeowner so that an explosion can be anticipated quickly.  This research carried out four tests: the sensor accuracy test, the sensor responsiveness test, the distance between the sensor and the leakage source test, and the responsiveness of the buzzer and LED test. The results of the tests show that the sensor only detects the LPG. The sensor readings are accurate since the value of Rs/Ro on the Tor-G is not much different from that of Rs/Ro on the datasheet, thus producing an error value in the 0% -0.08% range. The ideal installation position of the Tor-G is 75 cm from the gas cylinder and the danger warning system from the buzzer and red LED lights up within 18.88 seconds.

Liquefied Petroleum (LPG) is very common in daily cooking activities. Therefore, preventive measures must be taken to reduce the risk of fire and explosion due to LPG leakages. One action that can be taken is to install a regulator lever that can open automatically when a leakage is detected. In this research, Pulse Width Modulation (PWM) is used to control the rotational speed of the servo motor on the regulator lever, which aims to implement an automatic control system that is responsive when an LPG leakage is detected. Using servo motor control to automatically open the regulator lever can reduce the impact of accidents or losses due to LPG leakages. The test results show that the regulator lever can be opened effectively with a pulse value of 0.55 ms at a rotation angle of 0° in 0 seconds, while it can be closed with a pulse value of 2.45 ms at an angle rotation of 180° in 1.66 seconds. This shows that the regulator responds appropriately to the level of danger detected and is precise in adjusting position. The use of PWM on servo motors in the regulator control system has proven effective in increasing responsiveness to LPG leakages, as seen from the fast response (0 to 1.66 seconds) and accuracy (100% success percentage for 15 trials). This shows that using PWM can respond to emergencies quickly and precisely.

Smoking remains a significant public health challenge globally, contributing to a wide range of detrimental health outcomes including cardiovascular diseases, cancer, and respiratory disorders. Despite concerted efforts to curb smoking rates through policy interventions, effective monitoring and enforcement remain complex and resource-intensive tasks for health authorities and organizations. Innovative approaches leveraging advanced technologies such as visual detection systems powered by deep learning offer promising solutions to enhance smoking behavior detection and monitoring. Integrating the Google Cloud Vision API enables real-time identification of smoking indicators and discrimination from complex visual backgrounds. This capability not only supports proactive health monitoring but also strengthens the enforcement of public health policies aimed at reducing smoking prevalence. The research methodology utilizes a dataset of 600 images sourced from the Kaggle platform, encompassing diverse scenarios to optimize model training. Techniques such as image segmentation, feature extraction, and machine learning-based classification are employed to achieve high levels of precision and recall in identifying smokers and cigarette smoke. Despite the advantages of scalability, robust infrastructure, and high availability facilitated by cloud computing, the study acknowledges challenges such as bandwidth constraints and security risks associated with handling sensitive health data. Nevertheless, technological innovations in visual detection systems and cloud services are underscored as pivotal in mitigating the health impacts of smoking and advancing public health initiatives.

PT. PLN Nusantara Power Unit Generation Tenayan is a company operating in the Steam Power Plant sector in Pekanbaru, Indonesia. One of the main components of a steam power plant (PLTU) is a steam turbine. A steam turbine is a machine that functions to convert kinetic energy into electrical current. Operational failures are often caused by less than optimal instrumentation in the steam turbine. This research uses the failure mode and effect analysis (FMEA) method with the aim of identifying the type of failure, the cause of the failure, the effect of the failure, and determining the RPN value. The analysis results from this research show that the turbine instrumentation components still meet performance standards because the risk priority number (RPN) value is less than 200. The conclusion from this research is that errors in steam turbine instrumentation are inaccurate sensor readings, switches cannot deactivate the equipment, and readings control room does not match local readings, the instrumentation component with the highest risk priority number (RPN) is the solenoid valve with a value of 140, and the instrumentation component with the lowest risk priority number (RPN) is the pressure indicator with a value of 30. The component given top priority in action The recommendation is for the solenoid valve component, namely to carry out maintenance every 6 months and add an overspeed protection system

We were inspired to write this commentary because of an encounter at a conference where physicians told medical and undergraduate students that they laugh when patients Google search medical information. We recognized these actions to be rooted in oppression.  Despite public commitments made by the medical community and other health professional groups to combat racism and other forms of oppression, some healthcare encounters continue to be rooted in racism and discrimination. We specifically address anti-Indigenous racism and its impacts on the health and well-being of Indigenous Peoples to Turtle Island. We recommend the implementation of anti-racist and anti-colonial pedagogies to ensure that medical schools, other health professional programs, and healthcare institutions are training anti-oppressive care providers.
