The concept of bibliometric analysis, in addition to seeing the developments in any scientific field over a certain period of time, also provides information about where the scientific field in question will evolve in the future by offering a different perspective to understand the evolution of the field related to the concept. Bibliometric analysis method, which is used as an element or content in socio-economic fields such as communication, public relations, advertising, marketing, health, business, economy, finance and banking, technology, education, politics, etc., is the subject of many academic researches and numerous studies in the literature. The concept of bibliometric analysis is intricate and complex, and performing a bibliometric analysis of bibliometric analysis research will be able to provide a panoramic perspective to researchers and organizations in different disciplines. The research aims to evaluate the status of the concept of bibliometric analysis in the international literature within the framework of descriptive analysis with the document review method. For this purpose, after searching the Web of Science database and the necessary limitation procedures, a total of 18.432 published scientific studies published between 1980 and 2023 that include the concept of bibliometric analysis in all research, titles or keywords or have bibliometric analysis content were accessed. A total of 18.432 scientific studies accessed constitute the sample of the study. A total of 18.432 scientific studies with bibliometric analysis content were analyzed with the VOS viewer program to determine the scientific categories and interest orientation in which the interest in bibliometric analysis is concentrated, and the prominent country, organization, author and keyword concept units were reached with the publication-citation mapping technique. As a result of the research, besides the fact that the studies on bibliometric analysis are generally co-authored and that there is a high level of collaborative index in the fields of study, no common concept association related to bibliometric analysis or any common word concept or keyword association related to the expression bibliometric analysis was found.

Authors: Baştemur Kaya Ceren , Çakır Hasan
Published: July 2024

The process of learning a programming language is seen as complicated, especially for those who first start to learn programming language. For this reason, visual programming tools have begun to be used in educational environments. Visual programming tools purpose to concretize abstract programming language concepts. Alice program is one of the visual programming tools. The aim of this study is to determine the effects of the Alice program on programming learning in the education environment. The study group was 18 freshman students enrolled in the Object Based Programming I course at the vocational school computer technology department. The study lasted 8 weeks, with 4 hours each week. The teaching was realized on Gagne’s nine events of instruction model. At the end of the teaching process, two focus group interviews were conducted with the students to determine the obstructing and facilitating factors in using the Alice program. This study was utilized a descriptive case study. The data were analyzed by using the content analysis. When the results were examined; It was seen that the Alice program makes learning the basic code concepts easy and understanding programming logic, and increases the desire to learn programming. However, it was stated that the practicality of writing code could not be improved because code could not be written in the Alice program. It is thought that employing the Alice program is beneficial for enhancing comprehension of programming logic.
Trigeminal nerve hemangioblastoma in the setting of undiagnosed von Hippel–Lindau disease: illustrative case
Authors: Busch Nisha L , Matos Cruz Alejandro , Herbst John , Gyure Kymberly , Wegner Rodney , Yu Alexander , Shepard Matthew J
Published: July 2024

BACKGROUND

Von Hippel–Lindau disease (VHL) is an autosomal dominant tumor predisposition syndrome caused by mutations in the VHL gene. Patients with VHL are predisposed to developing numerous neoplasms, including central nervous system hemangioblastomas that typically arise within the cerebellum, brainstem, or spinal cord. The authors present the unusual case of a 69-year-old patient with a hemangioblastoma of the trigeminal nerve as his initial presentation of VHL.

OBSERVATIONS

A 69-year-old male presented with progressive right-sided V3 paresthesias, gait disturbance, and diplopia. Magnetic resonance imaging demonstrated an enhancing 0.5-cm nodule within the right trigeminal nerve and an associated peritumoral cyst exerting mass effect on the cerebral peduncle. Neural axis imaging demonstrated pia-based enhancing lesions concerning for multiple spinal hemangioblastomas. The patient underwent an uncomplicated retrosigmoid craniotomy for trigeminal nerve hemangioblastoma resection. The patient had postoperative improvement in his gait, diplopia, and facial paresthesias. Genetic testing revealed that the patient was heterozygous for a pathological mutation in the VHL gene.

LESSONS

Hemangioblastomas in adults over 50 years of age should prompt a workup for VHL. Recognizing that cranial nerves are a possible site of hemangioblastoma occurrence is important for neurosurgeons and radiologists alike. Resection of cranial nerve hemangioblastomas is technically challenging but can lead to symptom improvement for patients.

Candida parapsilosis intracerebral abscess and intralesional amphotericin B: a novel treatment approach to a rare infection. Illustrative case
Authors: Basson Dion , Kogilan Naidoo Theshan , Elliott Eugenne , Saul-Macala Yonella , Ding He Wen , Thomas Antony
Published: July 2024

BACKGROUND

Candida parapsilosis has been implicated in central nervous system (CNS) infections (i.e., meningitis or ventriculitis) but has not been previously reported to cause intracerebral abscesses. CNS infections secondary to C. parapsilosis are notoriously difficult to treat due to the poor CNS penetration of amphotericin B. Historically, intraventricular amphotericin B has been used to treat C. parapsilosis ventriculitis.

OBSERVATIONS

A 15-year-old female with no comorbidities presented with nonresolving headaches, photophobia, fevers, and meningism. Computed tomography (CT) of the brain revealed a right frontal abscess. After multiple drainage surgeries, subsequent CT scans showed reaccumulation of her abscess. C. parapsilosis was cultured, and the patient was then taken to the operating room where an external ventricular drain catheter was successfully placed within the abscess cavity. Pus was repeatedly aspirated, followed by the instillation of intralesional amphotericin B twice a day for 2 weeks. The patient’s clinical condition improved substantially with complete resolution of symptoms, improvement of infective markers, and resolution of radiological features of the abscess. Follow-up of the patient revealed the absence of symptoms and image characteristics of abscess on CT 3 months posttreatment.

LESSONS

Intralesional amphotericin B is a novel but effective treatment of C. parapsilosis intracerebral abscess, an organism not previously described as a cause of intracerebral abscesses.

Interlayer resistance of bilayer membrane to gas permeation
Authors: Ugrozov V. V.
Published: July 2024

To describe gas transfer through a bilayer membrane with a thin selective layer on the surface of a highly permeable gutter layer, it was first proposed to take into account the interlayer resistance arising at the boundary of this membrane layers and a model of gas transfer through a bilayer membrane was developed. An analytical expressions for permeability and selectivity of such a membrane taking into account this resistance is obtained. It is shown that the interlayer resistance can noticeably affect the transport characteristics of the membrane. It is found that even in the case of small diffusion resistance to gas permeation of the gutter layer, its sorption and kinetic parameters influence the permeability and selectivity of the membrane as a whole.
Prospects for the development of hydrogen energy. Polymer membranes for fuel cells and electrolysers
Authors: Stenina I. A. , Yaroslavtsev A. B.
Published: July 2024

Due to increased attention to hydrogen energy and the fact that many countries adopted the programs of its development the question of the prospects for this area becomes relevant. Initially, Russian hydrogen energy development program was focused on producing hydrogen from natural gas. However, owing to the changed international situation and the declared course to the use of “green” hydrogen, the production of which is not associated with the emission of carbon oxides, special attention should obviously be paid to the development of fuel cells (FC) and electrolysers. In this review, the main advantages and disadvantages of fuel cells of various types are considered. Today, the most developed industry is low-temperature fuel cells based on proton-exchange membrane. At the same time, fuel cells based on anion-exchange membranes with OH--ion conductivity are also promising. Their key advantage is the possibility of using significantly cheaper non-perfluorinated membranes and platinum-free catalysts. Considerable attention in the review is paid to fuel cells operating at elevated temperatures.
The second part of this review discusses in detail the membranes currently used in these devices and promising materials that can replace them in the near future.

Published: July 2024

Polynaphthoylenebenzimidazoles (PNBI) with keto-(PNBI-CO) and sulfonic (PNBI-SO2) bridge groups were obtained by solid-state polycyclization of polyaminoimides (PANI) synthesized by polycondensation of 1,4,5,8-naphthalenetetracarboxylic acid dianhydride with 3,3`,4,4`-tetraaminobenzophenone and 3,3`,4,4`-tetraaminodiphenylsulfone in N-methylpyrrolidone, respectively. The polycondensation process and resulting chemical structure of PANI and PNBI were controlled by 1H NMR, 13C NMR and IR spectroscopy. It is shown that the temperature of solid-state polycyclization change makes it possible to obtain polymers of several of cyclization degrees. The experimental values of the gas permeability and diffusion coefficients for He, H2, N2, O2, CO2, CH4 were obtained. The gas solubility coefficients and the ideal selectivity for various gas pairs were calculated. It has been established that, in terms of the permeability-selectivity ratio, completely cyclized PNBIs occupy a more favorable position compared to incompletely cyclized ones. This result is important for polymer and a method selection to develop a selective layer of new composite membranes. The gas transport characteristics achieved for competely cyclized PNBI-SO2, as well as the film-forming properties, along with the very high thermal stability of polymers of this polymer class, are interest of further expanding the range of PNBI obtained, as well as the prospects for such new polymers using of in various gas separation processes.

Published: July 2024

Water vegetation in lakes or reservoirs can change the water's ecology. Water vegetation in Jatiluhur Reservoirs is dominated by water hyacinth (Eichhornia crassipes). Water hyacinth in lakes or reservoirs becomes an invasive weed that can cause ecological degradation. Jatiluhur Reservoir is one of the water bodies affected by the uncontrolled growth of water vegetation. The study was conducted to determine the spatial and temporal distribution patterns of water vegetation and its effect on Jatiluhur Reservoir. Water vegetation's spatial and temporal distribution was analyzed using Sentinel-2A satellite image data. The Normalized Difference Vegetation Index (NDVI) algorithm was used to see the distribution of water vegetation in the reservoir waters. The observations show that the movement of water vegetation starts from the inlet area and then moves along with the flow of water to the center of the reservoir. Finally, it accumulates in the outlet area. The correlation between vegetation cover area and month of observation obtained the equation y=662.5x + 128.1. Based on the equation, the increasing vegetation cover area in the Jatiluhur Reservoir is predicted to reach 128.1 ha per month. The physical method used for controlling the growth and distribution of vegetation (water hyacinth) in Jatiluhur Reservoir by taking in the waters. Efforts to control vegetation physically must notice the increasing rate of water hyacinth distribution.
Analysis of Distortion and Fragmentation in James Joyce's Finnegans Wake
Authors: Ajmal Muhammad , Hussain Zahida , Bashir Rahat
Published: July 2024

The current study examined the elements of distortion and fragmentation as post modernistic deconstructive techniques in James Joyce’s ‘Finnegans Wake’. He used structurally and grammatically incorrect phrases and sentences in his works to represent the anarchy of traditional literary norms. The current study employed a literary close-reading approach to assess the disruptive traditional narrative structures and linguistic conventions of modern day literary texts. This study demonstrates Joyce’s uses of distortion and fragmentation to convey the themes of cyclical nature of history and the fragmentation in the novel. ‘Finnegans Wake’ by James Joyce is a semantically challenging novel since it is difficult to read and hard to interpret, with many scholars and readers proposing different theories about its semantic significance. The novel seems to be an example of avant-garde experimentation and a well written and recorded commentary on Irish history, culture, and politics. Moreover, the study also draws on critical and theoretical frameworks, including postmodernism and deconstruction, while contextualizing Joyce's use of distortion and fragmentation within broader literary and philosophical traditions and norms. Therefore, this current study contributes to the ongoing critical conversation around the selected novel ‘Finnegans Wake’. Additionally, it also offers new insights into Joyce's innovative and challenging literary style as how masterfully he knits fragmentation and distortion to depict anarchy and chaos in society, particularly, and in world, generally.

Published: July 2024

This report presents an evaluation of the concentration of total aflatoxins in a range of dry fruits obtained from local markets in Lahore, Pakistan. It also proposes some risk mitigation strategies through detoxification. The analysis involved appropriate techniques to accurately quantify the total aflatoxin (AF) content in each sample. According to the findings, AFs were not found in any of the branded dry fruit samples. However, AFB1 contamination in open samples of almonds, peanuts, apricots, walnuts, raisins, figs, and coconut was found in concentrations exceeding the EU guidelines. Furthermore, dry fruit samples collected from branded companies showed no AF- contamination. These findings suggest potentially high health risks posed by using dry fruits from open markets. This fact further emphasizes the importance of detoxification methods for safer consumption.

Authors: Tiwana Pernian Sanawar , Raheel Saman
Published: July 2024

The primary objective of this research is to investigate the knowledge, attitudes, and practices regarding menstruation among educated young adult females in urban and rural settings of Lahore (Pakistan). In pursuit of our research objectives, a total of six in-depth interviews were conducted with young adult females enrolled in both undergraduate and postgraduate programs within a public sector university in Lahore (Pakistan). The collected data underwent meticulous analysis utilizing a thematic approach. The study's findings highlighted the lack of sufficient knowledge among females upon the onset of menarche. Primary sources of information included mothers and elderly sisters; however, open discussions are frequently evaded or postponed on maintaining hygiene during the monthly cycles. Further, cultural, societal norms and religious considerations significantly influenced the imposition of restrictions and practices related to menstruation among females. The research elucidated the experiences of young females as they reflected on their initial encounters, and highlighted the challenges faced including religious and social constraints during menstruation in local settings. The study strongly advocated for the compulsory integration of sex education for both girls and boys at the adolescence stage in Pakistan, based on the identified gaps in knowledge and practices.

H. pylori affects more than half of the world's population and is associated with chronic gastritis, which can progress to serious complications such as peptic ulcer disease, gastric cancer, and MALT lymphoma. Epidemiological studies allow for the assessment of the level and changes in the prevalence of H. pylori infection. This paper addresses the results of H. pylori prevalence studies conducted in the Russian Federation. The high prevalence of H. pylori in adults and children in the 1990s and its significant reduction in recent years are reported. The prevalence of infection in adults is greater than in children in all time intervals studied, which is probably associated with poorer sociohygienic conditions in childhood in previous generations. The results of epidemiological studies on the prevalence of H. pylori are heterogeneous and depend on the time of the study, the region, and diagnostic method. The prevalence of H. pylori infection as determined by the 13C urea breath test has been found to be lower than that observed in serological studies. This discrepancy is attributed to the greater specificity of the breath test in detecting current infection KEYWORDS: Helicobacter pylori, epidemiological study, prevalence of H. pylori, Helicobacter infection, Russian Federation.

Gastroesophageal reflux disease (GERD) is widespread in the population due to the high incidence of its risk factors. Among these factors, epigenetic factors (excess body weight, obesity, smoking, the use of drugs that promote relaxation of the lower esophageal sphincter, hiatal hernia, etc.) play a significant role. The impact of these factors is primarily manifested through the development of persistent motor disorders at the esophagogastric junction. Furthermore, it is essential to consider the aggressive and protective factors of the esophageal mucosa when evaluating the risk of disease progression and categorizing patients at high risk for erosive reflux esophagitis and Barrett's esophagus in the general cohort of patients with GERD. A treatment approach based on risk factor modification and the use of combination therapy with a proton pump inhibitor and an esophageal protector has been demonstrated to enhance the efficacy of GERD treatment in a number of ways. Firstly, it has been shown to facilitate the achievement of clinical, endoscopic and histological remission. Secondly, it has been shown to prevent disease progression, particularly in patients at high risk for erosive reflux disease and Barrett's esophagus.

The alkali and alkaline earth metals such as potassium, sodium, barium and strontium are generally used as oxidizer in fireworks. The arbitrary use of these chemicals in fireworks is an acute issue responsible for higher emissions. Hence, efforts are underway to monitor these chemicals in fireworks. This work reports the precise determination of potassium and sodium in fireworks samples by flame photometry. The average deviation by flame photometry analysis was 7 to 8 % and 3 to 4 % for potassium and sodium, respectively, when the concentration of the respective metal nitrates in fireworks composition was less than 50%. The effect of different components in fireworks mixture, such as nitrate and metal precursor, were also studied to understand their impact on results. A brief study in terms of limit of detection (LOD), limit of quantification (LOQ) and dynamic range was also performed, which showed 0.42 and 3.26 mg/L as LOD and 1.29 and 9.88 mg L-1 as LOQ for the analysis of sodium and potassium, respectively. In summary, the study proved the prospective of flame photometry for determining sodium and potassium in fireworks samples.

The full-scale military invasion of the Russian Federation on the territory of Ukraine led to the emergence of a number of substantial destabilising processes and phenomena of a socio-economic nature, one of which is the strengthening of forced emigration of a substantial number of the economically active population of Ukraine. The purpose of the study was a comprehensive review and analysis of the current scientific legacy of papers devoted to the examination of the features, state, and problems of forced labour migration and identifying its impact on the national labour market and economic entities. The theoretical and methodological basis of the study as made up of general scientific heuristic methods, historiographic analysis and synthesis, comparison, and systematisation. Based on the results of the study, it was established that in the modern scientific discourse, the essence of forced labour migration is defined as a complex and dangerous socio-economic phenomenon that manifests itself in the uncontrolled movement of the population for the purpose of employment within the country and extends to other countries of the world. It was determined that most of the researchers are inclined to argue that the scale of forced labour migration has acquired threatening importance, the threatening trends of which were particularly acute during the war of the Russian Federation against Ukraine in 2022-2023, during which there is a critical increase in the volume of forced labour migration from Ukraine to European countries. There is an opinion among the scientific community that the processes of forced labour migration cause substantial problems in the national and international labour market. Most of the researchers argue that the most substantial problem caused by forced labour migration is the increase in the unemployment rate, which in Ukraine during the war reached 35% of the economically active population, which substantially unbalances the international and European labour markets, causing it to increase competition for highly paid jobs. Based on the assessment of researchers' opinions, the main ways to reduce imbalances in the development of the labour market in Ukraine and methods for minimising the risks of unemployment growth are proposed. The obtained research results can be used to create generalising reviews and more effectively work with the bibliography on the subject
