Authors: Khatun Monowara , Hossain Mahmood , Joardar Jagadish Chandra
Published: March 2024

Biochar, a carbonized biomass, can be used as a soil amendment for improving soil fertility and productivity as well as ensuring agricultural sustainability. Biochar can be produced from different materials and at different conditions, so its quality varies greatly as a soil amendment. In this respect, the present study aimed to explore the effectiveness of 4 biochars as a soil ameliorator for securing soil health. The biochars were produced from 3 different biomasses viz., rice straw, sawdust and water hyacinth and their mixture (co-biochar at 1:1:1) at 400 ºC. The biomasses and the biochars were characterized and the results revealed that conversion of biomasses into biochars caused a significant (p<0.05) increase in almost all of the biochar properties. Among the 4 biochars, water hyacinth biochar showed higher ash content, water holding capacity, surface area and total P, K, S, Ca and Zn. So, water hyacinth biochar could be a better choice as a soil amendment than the other three biochars. However, rice straw biochar showed higher cation exchange capacity (CEC), total N and Na and conversion efficiency of C, N, P, K, Na and Zn. Whereas, the co-biochar illustrated higher yield and showed the second highest in fixed C, CEC, total S, Ca and Zn and also in conversion efficiency of C, P, S, Na, K and Ca. Finally, it can be assumed to produce a co-biochar using rice straw at a higher ratio which might have a high potential for C storage and for supplying all of the essential plant nutrients.

Metatypical BCC of The Ear: Partial Amputation of The Auricle as Adequate Dermatosurgical Approach
Authors: A Hristova , L Ivanol , G Tchernev
Published: March 2024

Non-melanoma skin cancer is the most common cancer in the world (1). Basal cell carcinoma (BCC) is the most common malignant neoplasia of the skin, accounting for approximately 80% of all cutaneous tumors (2). High cumulative ultraviolet (UV) light exposure and the presence of Fitzpatrick skin phototype I or II are pathogenetic risk factors (3). UV radiation induces mutations in the tumor suppressor PTCH1 gene, leading to increased Hedgehog (XX/Hh) signaling pathway activity (4). Dysfunction or abnormal activation of the Hedgehog signaling pathway is associated with disorders of embryonic development and the development of cancers such as Goltz–Gorlin syndrome for example (5). BCC has the characteristics of a locally invasive, slow-growing skin cancer, with a metastatic incidence between 0.0028-0.5%, with areas in the head and neck most commonly affected (6). Metatypical basal cell carcinoma (MTBCC) is a rare variant of BCC that has histopathological characteristics of both basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) (7).

Accidents of Geography
Authors: Burton Elise K.
Published: March 2024

Over the past two decades, human geneticists have substantially embraced the concept of “biogeographical ancestry” to account for the racial, ethnic, and linguistic categories they use to analyze and interpret genetic difference. Understanding the ongoing role of these categories in human genetic research therefore requires attention to geneticists’ representations of geography, particularly the geographic maps they use to illustrate gene distribution and migration. This article examines how the methods and imagery of international genetic geography and its major evolutionary narratives have reinforced or refashioned nationalist practices of geography in the Middle East. Geneticists simultaneously conceptualize the region’s physical space as both a historical “crossroads” of human migration and the birthplace of distinct gene sequences and civilizations, alternately blurring and sharpening the boundaries between Europe and Asia. Focusing on genetic research in Turkey and Iran, this paper analyzes how geneticists draw and interpret geographic maps of the region while selectively erasing or highlighting state borders. These genetic maps negotiate between the idealized aims of international projects to reconstruct human evolutionary history, and the reality of practicing science under the constraints of nation-state politics.

In brief

Congenital ZIKV infection promotes alarming effects on male offspring's reproductive biology. This study showed the presence of the ZIKV antigen in the testis parenchyma, decreased testosterone levels, and sperm abnormalities in male offspring born to infected mothers.

Infection with ZIKV during pregnancy is associated with fetal developmental problems. Although neurological issues are being explored more in experimental studies, limited research has focused on the reproductive health consequences for offspring born to infected mothers. In this context, this study aimed to assess the impact of ZIKV infection during pregnancy on the testes and sperm of adult male offspring. Female mice were intraperitoneally inoculated with a Brazil strain of ZIKV during the 5.5th day of embryonic gestation. The offspring were evaluated 12 weeks after birth to analyze cellular and molecular changes in the testes and sperm. A novel approach combining variable-angle spectroscopic ellipsometry and machine learning modeling was also introduced for sperm sample analysis. The study revealed the presence of ZIKV protein in the testis parenchyma of adult male offspring born to infected mothers. It was shown that the testes exhibited altered steroidogenesis and inflammatory mediators, in addition to significant issues with spermiogenesis that resulted in sperm with DNA fragmentation, head defects, and protamination failure. Additionally, sperm dielectric properties and artificial intelligence showed potential for rapid identification and classification of sperm samples from infected mice. These findings provide crucial insights into the reproductive risks for men born from ZIKV-infected pregnant women.
Assessing Seasonal Changes in Physicochemical Traits and Biochemical Profiles of Key Carp Species in Masani Barrage Lake and JLN Canal
Authors: Yadav Sonal , Kumar Naveen
Published: March 2024

Our thorough seasonal analysis of Masani Barrage Lake and JLN Canal in Rewari reveals the profound impact of seasonal changes on aquatic ecosystems. Both water bodies display distinct patterns in temperature, pH, salinity, and other parameters. The unique characteristics of lakes, with greater temperature fluctuations and nutrient cycling, contribute to differences in phytozooplankton and ecological dynamics compared to more regulated canals. Additionally, our study on common carp tissues shows clear seasonal variations in moisture, ash, protein, lipid, and fatty acid levels, indicating specific metabolic responses to environmental conditions. Understanding these nuances is crucial for grasping the diverse influences of these habitats on fish physiology, with lakes experiencing more significant variations than canals due to their larger and more open systems.
A Cloud-Based Platform for Leaf Disease Segmentation and Classification using Hybrid Deep Learning Model
Authors: Subash L. , Arulselvi G.
Published: March 2024

This paper presents a cloud-based hybrid deep learning method for classifying leaf diseases. At first, sensors aid in detecting soil factors such as moisture content, pH level, air temperature, and humidity. The hybrid Recurrent Layer based Deep Convolutional Neural Network (RLDCNN) approach consists of five distinct stages: preprocessing, segmentation, handcrafted feature extraction, feature selection, and classification. The preprocessing of image involves removal of noise using Averaged Double Plateau Histogram Equalisation (ADPHE). Afterwards, the specific part of the image that is impacted is divided into segments using an improved Wavelet transform. After the process of segmentation, the GLCM (Gray-Level Co-occurrence Matrix) is used to extract features. The hybrid Fire Hawk with Egret Swarm Optimisation (FHESO) algorithm is a very efficient approach for feature selection, significantly lowering the dimensionality of features. The detection of apple, banana mango and groundnut leaf disease are accomplished via the use of a Recurrent Layer based Deep Convolutional Neural Network (RLDCNN), which is trained using the Deer Hunting Algorithm (DHA) that has been created. The suggested concept is implemented inside a cloud-based collaborative framework to provide immediate assistance to farmers. The experimental findings exhibit favourable outcomes, demonstrating a high level of accuracy, precision, a low rate of loss, recall, and F-score. The RLDCNN network method outperforms previous parameters, obtaining an accuracy of 98.51% according to comparative research.

Authors: Jara Gaspar Ricardo Junior
Published: March 2024

La clasificación exacta y temprana de la Displasia del Desarrollo de la Cadera (DDC) en pacientes pediátricos es imperativa para un tratamiento eficaz, reduciendo así las complicaciones a largo plazo. Las metodologías convencionales de diagnóstico manual muestran limitaciones, principalmente por la variabilidad interobservador y la necesidad de pericia especializada, llevando a diagnósticos inconsistentes o retrasados. Este artículo aborda esta problemática mediante la implementación de técnicas avanzadas de aprendizaje profundo para analizar radiografías pélvicas de infantes de 3 a 6 meses, utilizando ResNet50 para superar los desafíos del desvanecimiento del gradiente y proporcionar evaluaciones precisas. Adicionalmente, enfrentamos las cuestiones de privacidad, escasez y desequilibrio de los datos médicos aplicando Redes Generativas Antagónicas (GANs) para generar datos sintéticos de alta calidad, enriqueciendo así nuestro conjunto de entrenamiento y fortaleciendo la robustez de nuestro modelo. La integración del sistema propuesto con ResNet50 y técnicas de GANs fue clave para alcanzar una precisión del 97.3% en la clasificación de radiografías pélvicas con presencia o ausencia de DDC.

Authors: Mesa Torres Leonardo , Ramirez Salinas Yamilia
Published: March 2024

In the last few years, many researchers have been investigating the theoretical and experimental aspects of the of the use of the electromagnetic field and its effects on living organisms, and this is evidenced by the number of scientific papers published in different journals; however, there are no reports of a therapy that combines the use of the magnetostatic field (permanent magnets) and cryotherapy for the treatment of knee synovitis. The objective of this work lies in the design and simulation of a magnetic knee brace, with permanent magnets, for the treatment of SRP. It is concluded that magnetic induction generated by the configuration of the knee brace is feasible for this pathology and with cryotherapy it has high analgesic and anti-inflammatory effectiveness, since it relieves pain and inflammation caused by knee injuries (arthritis, osteoarthritis, SRP); and accelerates the rehabilitation time of athletes/physical exercise practitioners, with respect to conventional treatment; which has a direct impact on the patient's quality of life, mainly in the work, social and economic spheres.

Authors: ŚCIERANKA SANDRA
Published: March 2024

The tasks of a modern teacher are definitely different from those they had to perform a decade ago. In the era of various changes taking place, constantly developing, but also accompanying digitization in every sphere of life, the role of the teacher takes on a new meaning – flexibility and openness to changes on their part become necessary. Therefore, teachers face new challenges, roles and skills to expand. The conducted considerations are aimed at showing the impact of digitization both on the daily work of the teacher, the performance of professional functions, as well as his relationship with students. The punchline becomes the need to use artificial intelligence tools, as well as the essence and necessity of media literacy of modern teachers, which is reflected in the entire didactic process carried out among students shaped by digitization and the world of media. Among the others, the aim of the work was to determine attitudes of the educators (on the rating scale) about the presented approach to the work.

Authors: Buksa Łukasz
Published: March 2024

Digital communication has been evolving dynamically over the past few decades under the overwhelming influence of widespread access to the Internet, the development of mobile devices, especially smartphones, the popularization of instant messaging and social media. The use of Facebook, Twitter, Instagram, microblogs and blogs, and online communicators (such as WhatsApp or Messenger), among others, enables Generation Z and Alpha to exchange information with other users, post content or read posts. Online, mediated communication is what the young and children devote several hours a day to, sometimes with more emotional involvement than direct contact. They feel they are real participants in the virtual world, finding it more appropriate, more attractive than the outside world. The purpose of the article is to answer the question of whether this is true participation or rather a form of escape, a need for compensation, balancing deficiencies in needs, and what are the potential consequences of this.

PREDICTION OF PARAMETERS OF BOILER SUPERHEATER BASED ON TRANSFER LEARNING METHOD
Authors: Tong Shuiguang , Yang Qi , Tong Zheming , Wang Haidan , Chen Xin
Published: March 2024

The superheater in the boiler is the key of equipment connecting high-temperature steam to the turbine for power generation. At present, the problems of large variable fluctuations, strong timing coupling, and multi-power plant data utilization prevent the temperature, flow, and pressure prediction of the boiler superheater. In this paper, a method for predicting the parameters of boiler superheater based on a transfer learning model is proposed, which realizes the joint utilization of data from multiple power plants. The method first collects data from a waste incineration boiler power plant for pre-training the long short-term memory (LSTM)-transformer model, and then completes the transfer learning training on the new power plant. The proposed method has the advantages of high prediction accuracy, good robustness, and more reliable location prediction with drastic changes. The predictions on the test set are within ± 5% of the experimental value. Compared with the model not trained by the transfer learning, the proposed method achieves the lowest relative errors for all prediction intervals in the 3-15 min range. Compared to the linear regression (LR), support vector regression (SVR), and random forest (RF), the proposed method improves the average absolute percentage error (MAPE) by 30%, 13%, and 20%, respectively. Flatter loss sharpness value and better robust performance obtained from the transfer learning method is verified by an experimental verification. Finally, a digital system design for power plants with real-time data visualization monitoring, parameter prediction, and fault warning functions are implemented.

The performance of repair materials is greatly enhanced by the integrity of the rehabilitation system, which depends on the behaviour of the boundary or interface bond between the repair material and the concrete substrate. The effects of the implementation of repair materials (casting or spraying), the spraying direction and the roughness of the concrete substrate on the interfacial bond behaviour were experimentally investigated through four-point bending tests on prisms of size 300 × 76.2 × 40 mm. As a first step, 2 cm thick concrete substrates were fabricated with five different types of surface roughness. After 28 days of curing, the repair material (a high-performance (high-ductility) fibre-reinforced cementitious composite (HPFRCC)) was sprayed or poured into specific moulds. The HPFRCC was developed using local materials and had a tensile strain capacity of 3.7%. The spraying direction and surface roughness of the concrete substrate were found to impact the ultimate deflection rate significantly; upward spraying produced the lowest deflection rate and downward spraying the highest. Because beams are often repaired from the lower part and spraying is in the upwards direction, the casting method must be used because of the negative effect of gravity on the interfacial bonding between the concrete substrate and the repair material.
The Polish-Belarusian border in the sense of religious and cultural security in the 21st century
Authors: Zalewska Justyna
Published: March 2024

The article contains a report on research conducted on the Polish-Belarusian border in 2018, the aim of which was to identify the sense of religious security of the inhabitants of this region. The basic thesis is that the sense of religious security is related to formal belonging to a religious minority and individual experiences, which can be understood not only as personal experiences, but also as family ones, experienced in the past and passed down from generation to generation. It was assumed that religious identity and formal declaration of religion are part of broader cultural awareness, but do not determine the attitude towards the state. The article attempts to systematize the key concepts of security: religious, denominational and cultural. A characterization of a borderland person was made – that is, a person living at the crossroads of cultures – and the research results were discussed.
Security as a criterion for assessing the right to information
Authors: Niedźwiecki Ryszard
Published: March 2024

This article is based on the premise that law and ethics play a key role in prioritizing security and access to and dissemination of information. In most countries, and certainly in every democratic state, there are laws guaranteeing citizens the right of access to public information. This law recognizes the importance of transparency and transparency in the activities of government and public institutions. On the other hand, information has a huge impact on various areas of security, so there is a need to manage, protect and monitor information.

Dünyada yaşanan teknolojik gelişmelerin yanı sıra ekonomik krizlerin de her an ortaya çıkmasının muhtemel olduğu günümüzde, firmalar için performans ölçümü ve değerlemesi oldukça önemlidir. Ayrıca rekabetçi piyasa alanında da firmanın hem rekabet gücünün artırılması hem de piyasadaki yerinin belirlenmesinde performans tespitine ihtiyaç duyulmaktadır. Bu bakımdan firma performansının tespiti konusunda farklı yöntemlerden yararlanılmaktadır. Çalışma kapsamında Borsa İstanbul’da (BIST), İmalat Sektörü - Taş ve Toprağa Dayalı Alt Sektöründe işlem gören ve çimento imalatı faaliyetinde bulunan 10 firmanın 2013-2022 dönemine ilişkin belirlenen finansal oranlarının farklı kriter ağırlıklarına göre performans sıralaması tespit edilerek, kullanılan kriter ağırlıklarına göre uygulanan çok kriterle karar verme yöntemiyle firmaların piyasa değerleri kıyaslanmıştır. Kriter ağırlıklarının belirlenmesinde AHP (Analytic Hierarchy Process) ve Entropi yöntemleri kullanılmıştır. Çalışmada firmaların performansları, Cari Oran, Nakit Oran, Asit-Test Oranı, Net Kâr Marjı, Esas Faaliyet Kârlılığı, Özsermaye Kârlılığı, Finansal Kaldıraç, Satışlardaki Büyüme, Stok Devir Hızı, Aktif Devir Hızı, Özsermaye Devir Hızı ve Hisse Başına Kazanç olmak üzere 12 kriter dikkate alınarak, kullanılan farklı kriter ağırlıklarına göre TOPSIS (The Technique for Order of Preference by Similarity to Ideal Solution) çok kriterli karar verme yöntemiyle belirlenmiştir.
Le dispositif anti-COVID-19 de l’Université Alassane Ouattara au prisme des réalités du terrain

La maladie à coronavirus qui secoue le monde entier depuis décembre 2019, n'a épargné aucun secteur d'activités. La détection du premier cas de la COVID-19~en mars 2020 sur le sol ivoirien aura suffi à ordonner la fermeture des établissements d'enseignement primaire, secondaire et supérieur. Après avoir examiné la situation sanitaire, et probablement pour éviter l'année blanche, le Conseil National de Sécurité (CNS) ordonna, le 14~mai 2020, la réouverture des établissements éducatifs. Les chefs d'établissement devaient alors s'assurer de l'application stricte des mesures barrières édictées dans le cadre de la lutte contre la COVID-19. L'Université Alassane Ouattara s'appropria donc ces mesures. Malgré ce fait, des cas de COVID-19~y étaient détectés en juin 2020. En conséquence, les autorités universitaires réagissaient en adoptant des mesures sanitaires et pédagogiques afin de freiner la propagation du coronavirus. Ce chapitre se propose d'en faire un compte rendu. En s'appuyant sur des données empiriques collectées sur l'espace universitaire, l'étude analyse la réponse de l'Université Alassane Ouattara face à la pandémie du coronavirus, en mettant le focus sur les contraintes et opportunités occasionnées par la mise en place d'un dispositif anti-COVID-19.
Faiblesses de la mise en œuvre des mécanismes de gestion de la covid-19 dans le système éducatif au Cameroun

Published: March 2024

Au Cameroun comme de nombreux autres pays du monde où la pandémie du COVID-19~a été enregistrée, les écoles ont été fermées momentanément pour limiter l'expansion de la maladie. Diverses mesures ont été adoptées pour achever l'année académique 2019/2020. Dans ce chapitre, nous examinons les principales faiblesses des mécanismes de gestion du COVID-19~mis en place par le Cameroun dans le domaine éducatif afin d'assurer la continuité des classes. Nous nous appuyons sur la recherche documentaire et les enquêtes de terrain réalisées auprès du personnel enseignant et apprenant dans différentes villes du pays. Il ressort de cette réflexion que l'application des mesures de riposte mis en place par le gouvernement pour assurer la continuité des cours à la suite de la fermeture des établissements pour cause de COVID-19, présente de nombreuses faiblesses. D'un point de vue opérationnel, il a été relevé, en ce qui concerne la diffusion des cours à la télé, un accès inégal des apprenants aux équipements nécessaires pour ces cours à distance, avec une disponibilité irrégulière de l'électricité à l'échelle nationale. L'usage des plateformes en ligne et des réseaux sociaux n'a pas suffisamment été préparé, car non seulement près de 55 % des enseignants ne connaissent pas suffisamment utiliser ces nouveaux canaux (téléphones androïde, réseaux sociaux, etc.) pour dispenser les enseignements, mais aussi l'acquisition de tels équipements n'est pas à la portée de tous les apprenants.
Histoire du patrimoine culturel du Sénégal
Authors: DJIGO Adama
Published: March 2024

La patrimonialisation de valeurs et de biens culturels ou l’appropriation de l’objet patrimonial ne sont jamais « neutres » ; elles font apparaître des enjeux culturel, identitaire, sociologique ou politique. Il semble qu’au Sénégal, les opérations de mise en patrimoine et de valorisation de l’héritage culturel, initiées par l’État ou par des communautés, découlent des idéologies politiques et des préoccupations socio-économiques. Cet article essaie d’examiner les mécanismes et les logiques qui soutiennent l’institutionnalisation, les mises en scène du patrimoine culturel relevant du registre officiel ou des entreprises de quête de références identitaires. L’analyse tourne autour de la création, la restructuration et la normalisation par l’État (colonial et post-indépendance) de mémoires et traditions historiques. Le débat porte aussi sur les nouvelles imaginations, réappropriations de racines identitaires – déferlantes sur l’espace public – et qui résultent des dénonciations de systèmes politiques, socioculturels ou des tentatives de reformulation de valeurs.
