Abstract
The electrolysis of renewable energy to produce hydrogen has become a strategy for supporting a decarbonized economy. However, it is typically not cost-effective compared to conventional carbon-emitting methods. Due to the predicted intermediate of low-and zero-marginal-cost renewable energy sources, the ability of electrolysis to connect with electricity pricing offers a novel way to cost reduction. Moreover, renewables, particularly photovoltaics, have a deflationary effect on the value of the grid when they are deployed. This study investigates solar electrolysis configurations employing photovoltaic cells to feed a proton exchange membrane water electrolyzer for hydrogen production. Using experimental meteorological data at 1-min precision, the system has been evaluated in Baghdad, the capital of Iraq. Positioned at the yearly optimum tilt angle for the selected site, the solar array is rated at 12 kWp. Temperature effects on solar module energy loss are taken into account. Several electrolyzers with capacities ranging from 2 to 14 kW in terms of hydrogen production were examined to determine the efficacy and efficiency of renewable sources. MATLAB was utilized for the simulation procedure, with a 2021–2035 project lifespan in mind. The results suggest that a variety of potentially cost-competitive options exist for systems with market configurations that closely approximate wholesale renewable hydrogen. At 4313 h of operation per year, the planned photovoltaic array generated 18,892 kWh of energy. The achieved hydrogen production cost ranges between $5.39/kg and $3.23/kg, with an ideal electrolyzer capacity of 8 kW matching a 12 kWp photovoltaic array capable of producing 450 kg/year of hydrogen at a cost of $3.23/kg.

Abstract

Objectives
Collaborative Online International Learning (COIL) is an innovative teaching pedagogy involving faculty collaboration and student co-learning across global partner schools. Guided by the cross-cultural alignment model, the purpose of this educational research project was to analyze the impact of COIL on the knowledge, skills, and attitudes of nursing students in two global partner schools and to determine if groups of students were impacted differently.

Methods
Students engaged in synchronous and asynchronous learning sessions using a secure digital platform over several weeks. Data was gathered from students using an optional, anonymous, online, retrospective pre-posttest survey.

Results
COIL enhances student understanding of key global nursing concepts and culturally responsive care. Differences across schools were observed.

Conclusions
COIL is a feasible and cost-effective way to integrate global education into the curriculum of undergraduate nursing education. Recommendations for future COIL experiences are made.
An exceptionally rare case of Cushing’s syndrome caused by ectopic ACTH syndrome due to olfactory neuroblastoma in childhood

Published: January 2023

Abstract

Objectives
Ectopic adrenocorticotropic hormone secretion/syndrome (EAS) is caused by excess secretion of ACTH leading to hypercortisolism by non-pituitary, commonly malignant origins. We present a rare case of esthesioneuroblastoma (ENB) complicated by EAS in the follow-up period.

Case presentation
A child presented with nasal obstruction at the age of 10 months. Polypoid mass obstructing the right nasal passage was detected. Magnetic resonance imaging (MRI) showed a lesion limited within the nasal cavity. The lesion was completely removed by nasal endoscopic surgery. The pathologic examination revealed a diagnosis of esthesioneuroblastoma. It was confined to the nasal cavity so chemotherapy/radiotherapy was not administered and began to follow up. At 28 months of age, he presented with rapid weight gain. Laboratory data were consistent with Cushing’s syndrome (CS). High-dose dexamethasone suppression test and imaging studies led us to think of ectopic ACTH syndrome originated from ENB relapse. After partial resection of the tumor, ketoconazole treatment was started along with chemotherapy. Hypercortisolemia was kept under control with ketoconazole treatment as long as the treatment was maintained.

Conclusions
Cushing syndrome is a rare endocrine disorder. Adrenal sources of hypercortisolism and ectopic sources of ACTH overproduction should be investigated especially in young children.

Vegetal Cinema in Christine Montalbetti’s Novel Western
Authors: Bédard-Goulet Sara 
Published: January 2023

This article examines the vegetal agency taking place in the novel Western (2005) (Western: A Novel, translated by Betsy Wing in 2009) by contemporary French writer Christine Montalbetti. Building on the cinematographic performativity of the novel itself and on a materialist ecocritical approach, it studies the mobility of plants in this narrative to identify how the cinematographic transmediality contributes to engage the vegetal in the foreground. This analysis allows to feed the characterisation of cinematographic devices in the contemporary novel and to prolong the reflection on nonhuman agency and its presence in literature today.
The image of Hungarian Literature as a polysystem in Serbia: A brief overview
Authors: Čudić Marko 
Published: January 2023

AbstractThe paper offers a general overview of the place that Hungarian literature occupies in the polysystem of translated literature in Serbia. Unlike established philological disciplines with a longer tradition (English, German, French or Russian philology), which offer several different historical overviews of the history of a given literature, thus enabling the experts, the students and the general public to gain a more systematic insight into the respective literatures, there has only been one history of Hungarian literature published in Serbia so far. Given the fact that it was published back in 1976, and that many aspects of its methodology and insights have become outdated, it is an urgent necessity to produce a new work on the subject, specifically for the Serbian readership.
RESEARCH OF OSCILLATIONS DURING END-MILLING AND THEIR INFLUENCE ON THE FORMATION OF THE MACHINED SURFACE
Authors: Dyadya S. , Kozlova О. , Kushnir E. , Karamushka D. 
Published: January 2023

Purpose. Study of oscillations that occur during end-milling and their influence on the formation of the processed surface.
Research methods. The research was carried out using the experimental method, in which oscillograms of part oscillations were recorded with the allocation of cutting time during milling. Basic fragments of oscillograms were studied using the analytical method, on which the parameters characterizing the milling process were measured, and their relationship with the processed surface was determined.
Results. When milling with low spindle rotation frequencies, with down and up direction of feed, the part is affected by various types of oscillations, which are characteristic of the first and second speed zones of oscillations. During up and down end-milling, only forced oscillations operate in the first high-speed oscillation zone. In the second speed zone during up milling, the accompanying natural vibrations of the technological system are superimposed on the forced oscillations. It has been experimentally and analytically proven that the resulting deviation from the position of elastic equilibrium of the first wave of the accompanying oscillations affects the pitch and height of the waviness of the processed surface, which confirms the connection between the dynamics of end-milling and shaping.
Scientific novelty. The impact of accompanying free oscillations of the technological system during cutting on the formation of the processed surface is evaluated using parameters characterizing the dynamics of end-milling.
Practical value. The obtained results prove the influence of the cutting speed on the amplitude of the accompanying free oscillations of the technological system and provide an opportunity to choose cutting modes that ensure vibration stability of milling.

The study covers the free linear shrinkage of samples from PLA, HIPS, and ABS filaments used for FDM 3D printing in the ranges of extrusion operating temperatures (t). It was found that the PLA filament features by shrinkage values in the range of 0.2–0.6 % at Δt =200÷220 °С. HIPS filaments (Δt = 220÷240 °С) and ABS filaments (Δt = 240÷270 °С) have a shrinkage of 0.3–0.8 %. Linear shrinkage values must be taken into account when designing mathematical models of the future cast product. The influence of the print density dр (degree of internal structure filling) on the ash residue A when burning out samples obtained from the studied filaments was investigated. It was shown that the A value also increases with an increase in dр (5–15–30 %). The PLA filament has minimum A values (0.19–0.48 %). It was concluded that the PLA filament features the highest processability in the FDM 3D printing of casting patterns for casting into refractory ceramic molds (RCM) in terms of the set of free linear shrinkage and ash residue indicators. Clusters were made by FDM 3D printing from the PLA filament to produce «Nozzle» castings by casting into RCMs. Clusters were used to form RCMs. When burning out the clusters from RCMs, it was found that some RCMs cracked under linear heating. This was due to excessive pressure exerted by the expanding filament when heated to its softening temperature, and pressure exerted by gas emitted during the subsequent filament burn-out. The proportion of cracked RCMs increased with an increase in the heating rate. A stepwise mode of RCM heating combined with RCM calcination was developed in order to prevent cracking. There was no RCM cracking when clusters were removed in the stepwise mode. Experimental «Nozzle» castings were obtained from BrA9ZH3L bronze. The casting quality met the design documentation requirements.
Comparative analysis of the effect of Ni, Mn, Fe and Si additives on the microstructure and phase composition of hypereutectic aluminum-calcium alloys

Published: January 2023

A comparative analysis of the phase composition and morphology of primary crystals in hypereutectic alloys of the Al–Ca–Ni–X system (where X is Fe, Si, Mn) was carried out by calculation and experimental methods, including the construction of liquidus surfaces. Additional alloying of the base Al–6%Ca–3%Ni alloy with iron and silicon leads to the formation of coarse elongated primary crystals up to 100 μm in length. It was found that the addition of manganese, on the contrary, leads to the formation of relatively small (average size about 20 μm) compact primary crystals of two four-component phases. Presumably, they are phases based on ternary compounds Al9CaNi and Al10CaMn2. The composition of eutectics in quaternary alloys has been determined. All aluminum-calcium eutectics are characterized by a higher proportion of the second phases, a thinner structure compared to the aluminum-silicon eutectic in AK18 silumin, and are also capable of spheroidization upon heating, starting from 500 °C. The combination of compact and spherical particle morphology after annealing in the 63-2Mn alloy appears to be favorable for deformation. Comparison of the manufacturability of the experimental alloy Al–8%Ca–1%Ni–2%Mn and the grade silumin AK18 showed the advantage of the former. In terms of the totality of its characteristics, the experimental alloy can be considered as the basis for the development of hypereutectic alloys of a new generation as an alternative to piston silumins of the AK18 type. The experimental alloy, the microstructure of which is characterized by a compact morphology and small size of primary crystals and a fine structure of the eutectic, in contrast to hypereutectic silumins, does not require special modification.

Published: January 2023

Many approaches have been proposed using Electroencephalogram (EEG) to detect epilepsy seizures in their early stages. Epilepsy seizure is a severe neurological disease. Practitioners continue to rely on manual testing of EEG signals. Artificial intelligence (AI) and Machine Learning (ML) can effectively deal with this problem. ML can be used to classify EEG signals employing feature extraction techniques. This work focuses on automated detection for epilepsy seizures using ML techniques. Various algorithms are investigated, such as Bagging, Decision Tree (DT), Adaboost, Support vector machine (SVM), K-nearest neighbors(KNN), Artificial neural network(ANN), Naïve Bayes, and Random Forest (RF) to distinguish injected signals from normal ones with high accuracy. In this work, 54 Discrete wavelet transforms (DWTs) are used for feature extraction, and the similarity distance is applied to identify the most powerful features. The features are then selected to form the features matrix. The matrix is subsequently used to train ML. The proposed approach is evaluated through different metrics such as F-measure, precision, accuracy, and Recall. The experimental results show that the SVM and Bagging classifiers in some data set combinations, outperforming all other classifiers

Authors: Banerjee Swapan 
Published: January 2023

HIV impairs the immune system by attacking CD4 cells, a specific type of white blood cell. Most children living with HIV are found in Sub-Saharan Africa, yet this group has a dearth of data on cancer rates. Malignancies are common in children living with HIV, and immunosuppression and oncogenic co-infections are major contributing factors. This review study aims to sort and review the different diet types that may help boost innate immunity among HIV-positive children suffering from leukemiaWith the medical topic heading words (MeSH), this review was compiled from articles available without a subscription. HIV-related leukemia, the "inflammatory diet," "immunity-boosting food," and the "HIV diet kinds" were the others. This article only considers publications that have been published and are available online (in open-access databases such as the Directory of Open Access Journals, PubMed, Google Scholar, Semantic Scholar, etc.) between the years 2000 and 2022. As a result of extensive reviews, some effective diet types have come out to support the article’s objective, which is the best dietary approach to prescribe for HIV-induced leukemia. Micronutrient-rich dietary interventions, vitamin A-rich diets, Zinc enriched diet types, Neutropenic diets, Nordic diets, and some traditional Asian diets have been found significant and more effective for long years. The best, most affordable, and most commonly available strategy to maintain good health is to eat more foods that strengthen the immune system. According to the research, the Indian diet is complete with spices, citrus fruits, certain vegetables, herbal tea, honey, and other traditional foods that can strengthen the immune system. Research into diet and Ayurveda is being prioritized in many countries, including the West, mirroring India's approach..
