Authors: Sarah Abere  , Boma Oyan  , Okeke Uchenna
Published: May 2024

Background: Helicobacter Pylori, a class one carcinogen is common globally with about 50% of the world’s population affected. It causes severe symptoms and complications including peptic ulcer disease and gastric cancer in infected persons. This study therefore aimed to determine the prevalence of Helicobacter Pylori as well as the clinical profile of patients with upper gastrointestinal symptoms seen at the Rivers State University Teaching hospital. Methodology: One hundred consecutive patients with upper GI symptoms undergoing Urea Breath test who fulfilled the inclusion criteria constituted the study population. The data was analyzed using IBM-SPSS Statistics for Windows, Version 22.0. Results were presented as means ± standard deviation and percentages/number for quantitative and qualitative variables respectively, while Categorical variables were compared with Pearson’s Chi-square. Result: Of the one hundred patients studied, 35 (35%) were males and 65 (65%) were females with a mean age of 49.56 ±14. 68. The prevalence of Helicobacter pylori was 33% affecting more females than males. The most common symptoms in the patients at presentation were heartburn (51%), epigastric pain (47%) and dyspepsia (35%). There was an insignificant positive correlation between the detection of Helicobacter pylori and a prior exposure to proton pump inhibitors. Conclusion: There is a high prevalence of Helicobacter pylori among patients with upper gastrointestinal symptoms.

A comprehensive study of machine learning-based methods to predict epileptic seizures
Authors: Tehmina Nisar  , Rashmi Priyadarshini
Published: May 2024

People with epilepsy have many difficulties as a result of this complicated brain condition, which is typified by frequent convulsions. Symptoms of these seizures include bizarre behaviors, odd sensations, and in extreme cases, loss of awareness. These seizures appear as episodes of aberrant electrical impulses in the central nervous system. Successful epilepsy management depends on early seizure detection and identification, which allows for appropriate intervention to minimize risks and improve patient outcomes. Two major reasons have contributed to the extraordinary advancements in the area of epilepsy investigations in the last few years: the explosive development of machine learning techniques and the decreasing cost of non-invasive electroencephalography (EEG) apparatus. The availability of low-cost EEG equipment has made it easier to gather information on brain activity, which has opened up new avenues for monitoring and analyzing episodes of epileptic seizures away from conventional medical settings. The abundance of data and the advancement of machine learning methods have created new opportunities for the early identification and forecasting of seizures. Machine learning algorithms can predict seizures based on EEG data, providing patients with epilepsy with more control and informed decision-making. This paper offers a current review of current methods for treating epileptic seizures. The feature extraction techniques and classification algorithms receive particular focus. The most popular EEG datasets and their accessibility are listed. The approaches that are examined range from those that use more established machine learning techniques, such as naive Bayes models, Support Vector Machines (SVM), and Linear Discriminant Analysis (LDA), to those that take advantage of more recent deep learning techniques, like (Long-Short Term Memory, or LSTM), and deep Convolutional-Neural-Networks (CNN).

Authors: Showkat Hussain Gani
Published: May 2024

The primary objective of the current study is to examine how advertising impacts the consumer behavior of University students (N = 200). This study aims to delve into the influence of advertising on attitudes related to purchasing behavior. A questionnaire was developed to assess the effect of advertising, and the sample data were gathered from college/University students aged between 20 and 30. Specifically, eight fast-moving consumer goods (FMCG) brands, namely Lux, Pears, Dettol, Dove, Head & Shoulders, L'Oreal Paris, Dove and Tresemme, were considered in the analysis. The data collection process involved evaluating the correlations between these brands and their respective advertisements. The analysis encompassed the utilization of mean, standard deviation, frequency, and percentage, which were then presented in tabular form. The findings unveiled that advertisements play a pivotal role in steering preferences and choices, significantly influencing consumer buying behavior. The model employed in this study appeared to have a more pronounced impact on consumers compared to conventional modes of advertising. Additionally, the results indicated that consumers perceive advertisements as a credible source of information in contrast to other opinions, such as those from friends, neighbors, or reference groups. The study demonstrated that advertisements wield a substantial influence across diverse income groups, regardless of the economic bracket. Interestingly, the study found that the costliness of products and the frequency of advertisement repetition did not significantly alter consumer buying behavior. Among the brands considered, DOVE emerged as the most preferred, followed by PEARS. Notably, more consumers were affected by Dove and Tresemme's advertisement than by Head & Shoulders. Due to Head & Shoulder’s competitive pricing, users favor it over other shampoo brands. The flash of advertising on the big screen drew attention to it and had an impact on consumers.

Introduction: Primary biliary cholangitis is a chronic autoimmune hepatopathy and the leading cause of intrahepatic cholestasis. Treatment is mainly based on ursodesoxycholic acid. The aim of our work is to study the epidemiological, clinical and evolutionary profile of PBC, and to determine the factors predictive of a poor response to UDCA in our context. Materials and methods: This is a retrospective descriptive and analytical study of all cases of PBC followed in our training program from June 2012 to February 2023. Results: We recorded all clinical, diagnostic, therapeutic and evolutionary aspects of 70 cases of PBC. Ninety-two percent ( n= 65) were women. The mean age was 57.3 [24-83] years. The circumstances of discovery were dominated by pruritus, and jaundice. M2-type anti-mitochondrial antibodies were positive in 91.4% of cases. 52.14% of cases had associated autoimmune diseases. Treatment was based on UDCA in all cases, combined with corticosteroids and immunosuppressants for patients with overlap syndrome. A biochemical response after one year of treatment according to Paris II criteria was found in 62.85% (44 cases). In univariate analysis, the factors associated with poor response to treatment were : Discovery of cirrhosis at diagnosis , Decompensated cirrhosis , presence of overlap syndrome , poor compliance with UDCA due to non-availability of medication , initial bilirubin level above 30 mg/l , hypoalbuminemia below 35 g/l. Conclusion: Our study shows the frequency of cirrhosis in PBC, which may explain the low response rate to UDCA, a drug that remains difficult to obtain in our Moroccan context, making prognosis poor and management difficult.

Implementasi Kompresi File MP3 dengan Menerapkan Algoritma Levenstein
Authors: Anggraeni Lenita Cahya , Hastawan Ahmad Fashiha , Djuniadi Djuniadi
Published: May 2024

MP3 is an audio format that is often used because the data stored in MP3 format resembles the actual data when recorded.Storage space requirements will also rise if you keep a large number of MP3 files. Because of this, MP3 files must be compressed in order to prevent the storage space from filling up too quickly. This is because the compressed data will be lower in size. The Lossless compression method can be used to compress audio. The author uses the Levenstein Algorithm to implement audio compression in MP3 format. Levenstein's algorithm compresses data without any loss. When a file is compressed using lossless compression, the resulting file has the exact same size as the original file upon decompression. The author will be able to assess the effectiveness of MP3 file compression by using the Levenstein Algorithm to compress MP3 files. This will allow for faster transmission times and less data storage space consumption because the compressed MP3 file will shrink from its initial large size. After compression, the MP3 file's size—which was originally 128 bits—was reduced to 104 bits, yielding an 81.25% compression ratio. The purpose of this computation is to determine whether the compressed files are similar enough to be either decompressed or restored to their original size.

Impact of the distance between the draw holes on the ore loss due to congealing during ore drawing
Authors: Zubkov V.P. , Petrov D.N.
Published: May 2024

The paper considers the results of experimental studies of changes in the ore losses caused by congealing in the stoping zone during the drawing process in conditions of subzero temperatures in underground mining of eore deposits in the cryolithic zone, depending on the distance between the draw holes. Three series of experiments were performed using trench-shaped test benches with various distances betwen the draw holes. The distances between the access crosscuts were assumed to be 180, 200 and 220 mm, which is equal to 9, 10 and 11 m in actual conditions according to the adopted geometric scale of modeling. The results of modeling the bottom drawing in conditions of subzero temperatures, similar to the conditions of the underground ore mining in the cryolithic zone, showed that changes in the distance between the draw holes with the trench-shaped design of the bottom block have a significant impact on the extraction rates. When the distance between the draw holes is increased from 9 m to 11 m, the ore loss due to congealing during the draw phase rises from 24% to 42%. Experimental studies have shown that the increased distance between the draw holes in conditions of subzero temperatures in the bottom area leads to increased ore losses caused by congealing in the stoping area.

Mining The article discusses the main failure causes of centrifugal pumps used in the mine dewatering plants. The factors causing intensive wear of the impellers used in centrifugal pumps of the CNS-33-66...330 type are analysed, as well as the ways of increasing their serviceability. The gas dynamic cold spraying is recognized as the most promising and efficient method of applying functional coatings, which makes it possible to improve the condition of the surface layer and eliminate surface defects of the initial impeller blanks, which have a significant impact on the serviceability of the parts. The main research trends are outlined in the studied area, and practical recommendations are provided on using the gas dynamic cold spraying methid both in the pump manufacturing process and in their overhaul. It is shown that one of the promising trends in development the gas dynamic cold spraying applications is the creation of multilayer coatings on the impeller blades based on compositions of various metal-ceramic powders. Along with the hardening treatment, this combination will allow to provide the impellers with a set of necessary functional characteristics for the hydro-abrasive wear conditions. technological process as a sequence of changing the natural state of the Earth's subsoil to obtain a certain quantity and quality of mineral products is characterized by departures from the specified normative parameter values, which is due to causes of different nature. Most of these causes are man-made, anf they are created during the performance of specific process operations by the personnel. The article presents an original approach to managing the control over the technological process parameters in a coal strip mine. To reduce the magnitude and probability of the process departures from the normative values, the authors propose to create technical and organizational control loops. Each loop is a closed chain of technical means and organizational tools, which secures up-keeping of the normative technological process state. Production risk is proposed to be used as a criterion to assess the efficiency of the control loops. The methodology allowing to calculate the risk is described. The results of the contour approach application to the technological process control at the Solntsevsky coal strip mine are presented.
Analysis of the impact of local resistance of mine workings on the total mine air-flow resistance
Authors: Kobylkin S.S. , Ushakov V.K. , Kuznetsov I.I.
Published: May 2024

This paper aims to provide a quantitative assessment of the effect of local aerodynamic resistance on total mine airflow resistance with account for the friction resistance. The research includes laboratory tests, computer simulations in the Ansys CFD software as well as analytical inferences. The performed studies specified the magnitudes of local resistances at the turnings of mine workings. It has been established that the value of local resistance in all the sections can exceed 10% of the total mine aerodynamic friction resistance. This depends on the geometric parameters of the mine workings, which may result in a significant increase in the ratio of the local resistance value to the aerodynamic friction resistance value. The correlation of the two coefficients, i.e. the friction coefficient and the coefficient of local resistances, are proved to have a significant impact. The sharper the turns of the mine workings are, the greater the ratio of the local resistance to the aerodynamic friction resistance value is. Therefore, it is necessary to take this type of resistance into account when designing mine ventilation systems.
To be or not to be a state? The alignment behaviours of Abkhazia and South Ossetia with Russia
Authors: Aslund Anton
Published: May 2024

This article presents an adaptation of Kuik's hedging theory to analyse the secessionist movements in Abkhazia and South Ossetia, both seeking independence from Georgia with Russian support. By examining their distinctive strategies, this study addresses the extent to which these regions seek to maintain their independence from Russia, as their patron state. The article argues for the need to modify hedging theory to accommodate the unique context of former Soviet actors and de facto states. The adaptation develops the concept of a "political hedge," with a focus on elite-driven nation-building as a mechanism to influence the likelihood of Russian integration. Abkhazia is identified as an illustrative case of hedging behaviour, whereas South Ossetia displays characteristics resembling but distinct from bandwagoning. This analysis contributes to refining the applicability of hedging theory within novel political environments and underscores the significance of elite-led nation-building in shaping state and national legitimacy in secessionist regions.
Putin’s retelling of the Great Patriotic War myth and the construction of Russian national identity
Authors: Preen Alexia
Published: May 2024

Political elites often use the nation’s past to construct the nation’s present identity. In his speeches about the 2022 invasion of Ukraine, President Vladimir Putin frequently uses the Russian national myth of the Great Patriotic War to construct Russia’s present duties, values, and identity. Charges of neo-Nazism and fascism against Ukraine are made to construct the Russian national identity as one that fights proactively against Nazism. However, by using a myth set in the Soviet period, the status of Ukraine as either part of the Russian Self or constituting the foreign Other is highly ambiguous. Although cynical and deeply offensive, Putin’s use of Nazi imagery therefore has a purpose deeper than causing shock and offence.

Authors: Lyes Georgina
Published: May 2024

This paper investigates the effectiveness of current approach to third-country immigrant integration in Europe and assesses the potential for increased EU involvement in shaping integration strategies. Analysing disparities in immigrants' treatment and rights across EU member states, the paper reveals barriers to achieving successful integration and equal rights. The paper contemplates the complex interplay between integration, national sovereignty, and rising nationalism, necessitating careful consideration in any proposed EU intervention. Ultimately, the paper underscores the importance of a comprehensive two-way approach to integration, grounded in respect and empathy, highlighting the potential for EU involvement to address systemic challenges and foster a more inclusive European society.
Zoomorphic Incense Burners of Medieval Khurasan: A study of Islamic metalwork
Authors: Kelly Elizabeth C.
Published: May 2024

Zoomorphic incense burners were produced in medieval Khurasan between c.441-597/1050-1200. This book examines their role, function and meaning. It includes a database with defined classification criteria that enables them to be contextualised with other contemporaneous metalwork. Multicultural medieval Khurasan prospered from mercantile activities facilitated by the trade routes. The increased wealth, including middle-class patronage, movement of artisans and goods, along with the resultant transcultural exchanges, all contributed towards a changing aesthetic in artwork that reflect interests and lifestyles. The zoomorphic incense burners that emerged during this time displayed a hybridised iconography of feline and equine characteristics. The analysis indicates they are associated with symbols of power, sovereignty, the military and hunting. Their decorative palmette motifs provide representations of esfand, a plant considered to have talismanic and apotropaic properties known for inducing bravery amongst warriors.
From Iceland to New Iceland: An archaeology of migration, continuity and change in the late 19th and early 20th centuries
Authors: Edwald Maxwell Ágústa
Published: May 2024

In 1876 Páll Gunnlaugsson and Nanna Jónsdóttir auctioned off their belongings and emigrated from Iceland to North America with their two young sons. A year earlier, Jón Guttormsson and Pálína Ketilsdóttir emigrated from a different Icelandic fjord with their young son Vigfús and settled in New Iceland, Canada. This book looks at the processes of migration and settlement, and the cultural changes and continuities that arise from entanglements with new environments. It weaves the results of archaeological excavations at two farms, Hornbrekka, Iceland and Víðivellir, New Iceland together with the rich historical archive of the emigration period. The discussion focuses on four themes through which specific changes in the lives of the emigrants and their descendants are explored: ethnic identity, wealth, improvement, and modernity. The book provides a critical examination of how change occurs through continuities and argues that either/or categories are inherently unhelpful in explaining cultural change.
In Search of Norfolk’s First Stone Churches: The use of ferruginous gravels and sands and the reuse of Roman building materials in early churches
Authors: Wade-Martins Peter
Published: May 2024

This work takes a fresh look at the evidence for early church building in Norfolk, focusing particularly on how locally available stone and the materials from ruined Roman buildings were reused in Norfolk’s first stone churches. The author first identifies the stones and Roman materials used in early church buildings before limestone ashlar was readily available. A second section reviews and presents survey results from more than 650 churches in the county. Finally, the author presents an illustrated catalogue of the study sites which will serve as a foundational reference for any researcher interested in Norfolk’s ecclesiastical and architectural history. As a result, Wade-Martins revolutionises our understanding of early church buildings in the county, identifying many early buildings which were not previously recognised.
Flax lines mutant for chlorophyll coloration in the genetic collection of VIR

Photosynthesis is one of the main biological processes that ensure life on the planet. The use of knowledge about the genetic control of chlorophyll biosynthesis will help to increase the productivity of flax. The paper presents a study of hybrids from the crosses of five lines defective in chlorophyll coloration and five with green coloration of the plant, differing in other morphological characteristics.

Inheritance of 4 nuclear genes controlling the chlorophyll coloration of the plant has been established. The independent genes ygp1 (in the gc-210 line) and ygp2 (in the gc-473 line) control the yellow-green coloration of a young plant (Xanthovirescens). The complementary interaction of these genes, which causes the yellow color of a young plant, has been demonstrated. The genes ygp2 (in gc-473) and ygp2-2 (in gc-570) were proved to be allelic but not identical, since mutations were obtained independently. The non-cumulative polymeric gene interaction which has been established in the case of zeb1 and zeb2 genes (both in the gc-281 line), cause an increase in photosensitivity and alternation of white and green stripes of leaves (Viridoalbostriata). These genes mask the action of the ygp1 and ygp2 genes. For the first time in the world, the maternal type of inheritance of the chlorophyll coloration of the plant, controlled by the chloroplast gene ygp3 of the gc-480 line, has been established in flax. It was found that the gc-570 line, in addition to the ygp2-2 gene, is homozygous for the genes CSB1 (ciliation of the false septa of the boll) and YSED1 (dominant yellow seeds), while the gc-480 line, in addition to the ygp3 gene, is homozygous for the CSB1 and dlb3 genes (light blue corolla). The allelism but not equality of the dlb3 genes in the gc-480 and gc-210 lines has been proven. The genes ygp1 and ygp2, which are responsible for chlorophyll coloration may be promising for labeling varieties. It is necessary to study them in more detail for the possible creation of plastic varieties capable to endure unfavorable environmental conditions at early stages of development.
