Published: September 2024

Objectives

To determine the etiological profile of suspected cases of bacteremia
To establish the antibiotic susceptibility pattern of bacterial isolates

Materials and Methods:
The retrospective study was carried out from January 2022 to December 2022 at Islamabad International Hospital. A total of 639 blood culture isolates were processed manually onto blood agar, chocolate agar, MacConkey’s agar, and bile-esculin agar and were identified on their morphological appearance using gram staining. Isolates were further identified at the species level using the Analytic Profile Index (API). Antibiotic susceptibility testing was performed using the Disk Diffusion method as per Clinical and Laboratory Standards Institute guidelines (M-100 Version 2021)
Results:
Amongst 639 blood culture isolates, only 66 (10.32%) were culture-positive. Prevalent gram-negative bacilli included Salmonella typhi (n= 19) and Escherichia coli (n= 8) whilst Enterococcus (n=4), and Staphylococcus aureus (n=4) were the predominant gram-positive cocci. Salmonella typhi and S. aureus showed 100% resistance to ciprofloxacin whilst enterococcus displayed 75% resistance. Overall, all strains (n=6) of K. pneumoniae and 63% of E. coli showed resistance to over 4 antibiotics.
Conclusion:
Gram-negative bacteria were the main cause of BSIs, where the predominant microorganism was S. typhi. Remarkably all S. typhi isolates were completely resistant to ciprofloxacin.

Authors: Ajit B. Kolekar Sagar B. Porlekar,
Published: September 2024

From the standpoint of safety, the braking system is an essential part of the motorcycle. The capacity of the brake disc composition to endure excessive frictional and durability to wear rate is the most crucial factor to take into account. Tolerating the maximum temperature that developed as a result of friction is also needed. Hence to increase the performance of brake disc we need to improve the thermal performance of brake disc. Thermal performance of brake disc is depending on the kind of material utilized for manufacturing of brake discs. As we know, brake disc assembly is rotating and moving from one place to another place in the actual application. Hence it is challenging task to do thermal analysis of brake disc experimentally. In this present study experimental setup is proposed for measuring the brake disc's surface temperature which can be useful to do the thermal analysis of the brake disc.

Published: September 2024

Atherosclerosis is the mechanistic basis of cardiovascular disorders manifested by damage to the walls of the aorta, coronary, cerebral and peripheral arteries, leading to the development of acute or chronic ischemia of internal organs and tissues. This publication describes a case of spontaneous atherosclerotic lesion of the aorta with the formation of a dissecting aneurysm in an African green monkey male. The ancestors were introduced from Ethiopia and Europe. The case monkey was housed as a family group in an outdoor enclosure with attached smaller room equipped with heating system. It lived 16.4 years. Pathological diagnosis was established through complete autopsy and histopathology. Main disease was chronic atrophic gastroenterocolitis in exacerbation complicated with alimentary dystrophy, cachexia (brown atrophy of the myocardium, liver, skeletal muscles). The concomitant diseases: complicated atherosclerosis of the aorta, dissecting abdominal aortic aneurysm with a large cylindrical organized thrombus in the aneurysm area, stenosing atherosclerosis of the renal arteries, vascular wrinkled left kidney; focal atherosclerosis of the coronary arteries and their branches with small foci of atherosclerotic cardiosclerosis and arteriosclerosis of cerebral arteries. The revealed changes indicate a significant similarity in the pathomorphogenesis of atherosclerotic lesions in African green monkey and humans. It allows us to consider this genus of primates as a promising laboratory model for studying the pathogenesis and mechanisms of regression as well as the effectiveness of therapeutic approaches to the treatment of atherosclerosis and its complications.

Published: September 2024

Advanced age, called geriatrics, negatively affects the aging–related physiological changes on bodysystems. non–steroidal anti–inflammatory drugs (NSAIDs) used in geriatric pets or humans have negative effects on the kidneys. For this purpose, , the effects of Meloxicam and Flunixin Meglumine, which are NSAIDs frequently used in Veterinary Medicine, on the liver and kidney structure and function in geriatric male rats were evaluated. Twenty–four male geriatric rats (30–36 month old) and twenty–four 3–month–old young male Wistar albino rats were used in the study. Six groups were created, with eight rats in each group: young control (YC), young Meloxicam (YM), young Flunixin Meglubine (YFM), geriatric control (GC), geriatric meloxicam (GM), geriatric Flunixin Meglubine (GFM). Control groups (YC and GC) received an intraperitoneal injection of saline using the same volume as in the othergroups. Meloxicam was administered at 5.8 mg·kg-1 to the YM and GM groups, and Flunixin Meglumine at 2.5 mg·kg-1 intraperitoneally to the YFM and GFM groups once a day for 5 days. Neutrophil Gelatinase–Associated Lipocalin (NGAL), Cystatin C (Cyc–c), Kidney Injury Molecule–1 (KIM–1), Interleukin–18 (IL–18), Urea, Creatinine (Crea), Albumin (Alb), and Total Protein (TP) levels, were determined in sera and urine samples. Serum NGAL, Cys–C, and KIM–1 levels in the GC group were found to be significantly higher than those in the YC group (P<0.05). Administration of both NSAIDs caused an increase in serum Cyc–c and NGAL levels in both young and geriatric rats (P<0.05). Since both Meloxicam and Flunixin Meglumine administration caused an increase in NGAL and Cys–c levels in young and geriatric rats, adjusting the drug dose and frequency of administration by evaluating the pretreatment renal function should be considered as a preventive measure.

Ante la disminución de la oferta forrajera ocasionada por los eventos de variabilidad climática, los subproductos de cosecha del café (Coffea arabica), pueden ser una alternativa para la suplementación bovina, en zonas productoras de café. El objetivo de este trabajo fue evaluar la inclusión de ensilaje de cáscara (pulpa) y mucilago de café (ECMC), sobre variables productivas de vacas doble propósito en pastoreo, como estrategia de suplementación estratégica, en la provincia Comunera del departamento de Santander, Colombia. Los tratamientos fueron: pastoreo + ECMC (T1) y pastoreo + alimento balanceado (T2); el ECMC se ofreció a razón de 2 kg·animal-1·día-1 y el balanceado a una dosis de 1000 g·animal-1·día-1, distribuidos en dos ordeños. Los animales pastoreaban praderas de Brachiaria decumbens de 25 días de rebrote. El ECMC tenía un tiempo de almacenamiento de 10 meses al momento de ofrecerlo a los animales. Se utilizaron 12 vacas multíparas doble propósito que registraban 105 días de lactancia. El efecto del ECMC se evaluó durante dos secuencias de medición, cada una de 12 días (siete de adaptación y cinco de medición). La producción de leche (L·vaca-1·día-1), proteína (%P), grasa (%), sólidos totales (%ST), lactosa (%Lac) y nitrógeno ureico en leche (NUL mg·dL-1) se analizaron mediante un diseño de sobre cambio. No hubo efecto de la suplementación con ECMC (P>0,05) sobre la producción de leche (13,5 y 14,2 L·vaca-1·día-1, para las vacas de T1 y T2, respectivamente), ni sobre las variables de composición láctea. En otros estudios también se ha evidenciado el mantenimiento en la producción de leche al utilizar ECMC. Los ECMC pueden ser una opción promisoria para la suplementación bovina, sin embargo, en Colombia es necesario seguir evaluando aspectos de calidad composicional, niveles óptimos de uso y respuesta animal, de esta clase de residuos de cosecha.
Empowering Deaf Students : A Genre Analysis of the film Children of a Lesser God
Authors: Dr. Najla Mosbehi
Published: September 2024

People with hearing loss often need special skills to learn language and communicate. The film Children of a Lesser God focuses on the link between hearing impairment and speech. It portrays the way deaf students struggle to gain hospitality in the hearing world. It revolves around a romantic relationship between a deaf girl and a hearing speech teacher. This paper tackles the communicative skills that James achieves with his deaf students and Sarah through genre analysis as an analytic angle. It has been found that James uses innovative teaching techniques to help his deaf students have a better understanding for somatic sensations, such as vibration, playing loud rock music, reading hi lips and interpreting his sign language. Children of a Lesser God delves into the intricate challenges faced by individuals with hearing loss in the realm of language acquisition and communication. This exploration revolves around the romantic relationship between James, a hearing speech teacher, and Sarah, a deaf former student, uncovering the interplay between hearing impairment and expressive language skills. The film also challenges societal attitudes toward deafness, questioning whether it is viewed as a limitation or a distinctive mode of communication. This genre analysis provides a comprehensive examination of how the film surpasses conventional norms of the romance genre while shedding light on the innovative teaching methods employed by James to support his deaf students and his girlfriend, Sarah. The central conflict of the narrative arises from the contrasting communication styles and perceptions of James and Sarah. Sarah’s resistance to conforming to the hearing world presents a unique challenge for James, who endeavors to connect with her through American Sign Language (ASL). The film’s title, Children of a Lesser God, underscores societal attitudes toward the deaf, framing the exploration of autonomy, understanding, and the right to define one’s identity. Beyond the romantic storyline, the narrative expands to address the broader challenges faced by deaf students in their pursuit of education and communication. In light of the limited research on the intersection between films and language pathologies, especially deafness, this study uses genre analysis to explore the film’s distinctive exploration of communication dynamics and educational practices. The primary objectives include examining how the film transcends conventions of the romance genre and deciphering the teaching methods employed by James to empower deaf students.
Identity Crisis and Human Predicament in Vikram Seth’s A Suitable Boy and Chitra Banerjee’s Queen of Dreams
Authors: Suhani Nagar  , Dr. Ashutosh Dubey
Published: September 2024

Several factors contribute significantly to shaping an individual’s identity and distinguishing the cultural ethos of a particular group or community from others. These factors intricately interconnect with the evolution of diverse cultural practices and beliefs within a given community or geographical area. This complex interplay includes elements such as the ecological context of a region, the foundational functioning of economic institutions, the structure of family units, upbringing practices for children, as well as the narratives woven through tales, myths, legends, and historical events. This research paper delves into the exploration of identity crisis and human predicament as depicted in Chitra Banerjee Divakaruni’s Queen of Dreams (2004) and Vikram Seth’s A Suitable Boy (1993). Vikram Seth aims to explore his profound and committed humanistic concerns evident in his novel, A Suitable Boy (1993). Seth’s works delve into the human condition within a chaotic society. He dedicates his art and craft to the study and observation of characters, attitudes, and behaviours of individuals he encounters in contemporary life. Seth’s primary focus revolves around universal human elements like loneliness, alienation, love, passion, marriage, family, music, changing times, corruption, realism, nuclear madness, and disarmament. Seth’s literary world often portrays frustration, destruction, and disappointment. He emphasizes fulfilled love that leads to marriage and family, prioritizing rational love over superficial or romantic notions. Each of his novels concludes with a sense of disappointment and withdrawal from happiness. His vision of love and relationships centres on social stability, security, togetherness, and social order. Seth distinctly favours the institution of marriage and family, forming a thematic cluster that characterizes his works. Divakaruni’s novels stand as a testament to the preservation of her homeland’s cultural heritage. Her literary works vividly depict characters embracing a bicultural identity. Divakaruni skilfully interweaves Indian heritage with the American experience, offering a unique perspective on the South Asian Diaspora. These diasporic cultures arise from the dispersion of diverse communities across the globe, driven by various historical and obligatory factors. Throughout her body of work, Divakaruni delves into the profound identity crisis experienced by women, as they embark on a quest to discover their genuine selves. In her capacity as an immigrant writer, she stands out from her contemporaries, as she skilfully brings together women from diverse backgrounds, communities, ages, and nationalities. These women find a common bond in their shared experiences and relationships while residing in foreign lands.

Nature and Imagination: Influence of the female poets of British Romanticism on the poetry of Rabindranath Tagore
Authors: Baharul Sheik
Published: September 2024

This research article explores the profound influence of female poets from the British Romantic Canon, specifically Charlotte Smith (1749-1806) and Felicia Dorothea Hemans (1793-1835), on the poetic works of Rabindranath Tagore (1861-1941), focusing on their treatment of Nature and Imagination. While the Romantic Period traditionally emphasizes male poets, this study contends that the contributions of female Romantic poets are equally significant in shaping literary discourse. Tagore, a renowned figure in Bengali and world literature, was deeply influenced by the poetic themes and stylistic innovations of British Romanticism. Smith and Hemans, through their exploration of nature as a source of sublime beauty and spiritual inspiration, introduced Tagore to a poetic sensibility that transcended geographical and cultural boundaries. Their emphasis on the emotional and imaginative response to natural landscapes resonated profoundly with Tagore’s own philosophical and poetic outlook. This article employs a comparative analysis of selected works by Smith, Hemans, and Tagore to delineate the thematic and stylistic affinities between them. It examines how Tagore adapted and synthesized elements of Romantic poetics, particularly the celebration of nature’s evocative power and the privileging of individual emotion and intuition. Moreover, it investigates how Tagore, drawing from his exposure to British Romanticism through translations and critical engagements, incorporated these influences into his own literary oeuvre, thereby enriching the aesthetic and philosophical dimensions of his poetry. By reassessing the role of female Romantic poets in shaping Tagore’s poetic imagination, this study contributes to a broader understanding of cross-cultural literary exchanges and the transcultural dynamics of literary influence. It underscores the transformative impact of transnational literary connections in fostering innovation and diversity within literary traditions. Ultimately, this research elucidates the enduring relevance of the British Romantic Canon and its female voices in global literary landscapes, highlighting their lasting impact on Tagore’s literary legacy.

Published: September 2024

The positivistic style in the development of science in the modern period resulted in the dichotomy of science and religion and the loss of moral values, giving rise to many wars. In this case, religion is considered a moral control that maintains social harmony. This research aims to discover the relationship between social science (as a form of scientific knowledge) and religious science, as well as efforts to shape the relationship between the two. This research is a library research study using the Titus epistemological approach. This research found that firstly, the objects of study in social science and religious science are compatible with humans and their environment, even though in religion the object of study is physical and metaphysical, while in social science the object is based on reason and empirical. Second, the research methodology of social science is different from religious science except in the case of hermeneutics. Third, the concept of validity between the two is different. From these three findings, it can be concluded that the ‘dialogue’ relations between social science and religious science in terms of epistemology is in humans and their environment, and the existence of hermeneutics in its methodology.

BÜYÜK İSTİFA DALGASI VE TÜRK İŞGÜCÜ PİYASALARI: YAPISAL PERSPEKTİFTEN BİR ANALİZ
Authors: Baştürk Şenol
Published: September 2024

Pandemi döneminin işgücü piyasalarında yarattığı en ilgi çekici sonuçlardan birisi, kapanma döneminin ardından gönüllü istifa oranlarının çarpıcı biçimde artışıdır. Akademik araştırmaların büyük bir kısmı, büyük istifa olgusuyla 21. Yüzyılın çalışma karşıtı kültürü arasında bağlar kuran işgücü arz açıkları perspektifine sahiptir. Ancak bu yaklaşım, olgunun boyutlarını anlama ve işgücü piyasalarındaki farklılaşmaları kavrama konusunda yapısal perspektif tarafından yetersiz bulunmuştur. Yapısal perspektifteki çalışmaların ampirik sonuçları, büyük istifanın ücretli çalışmadan çıkma olarak tanımlanmasını desteklemez. Hareketliliklerin tabakalı işgücü piyasalarının mantığına uygun olarak birincil işgücü piyasalarında dijital beceri sahiplerinin fırsat alanlarının genişlemesine; ikincil işgücü piyasalarında ise çalışanların düzenli işlere geçişi şeklinde iki temel biçime sahip olduğunu iddia eder. Bu çalışma yapısal perspektifin varsayımlarının Türk işgücü piyasaları için test edilmesine odaklanmaktadır. Yapılan betimsel analizde, Türkiye’de pandemi döneminde işten işe geçişlerin özellikle ikincil işgücü piyasalarında arttığını ve bunun düzenli işlere geçişlere uygun bir niteliğe sahip olduğunu göstermiştir. Buna karşın birincil piyasalarda benzer bir hareketliliğe dair bulgular ile karşılaşılmamıştır.

Aim: To evaluate and compare the load to failure testing of an all-ceramic material based on their processing techniques. Methods: 24 copings of all ceramic lithium disilicate were fabricated using the press technique (n=12, Group 1) and milling technique (n=12, Group 2) on mandibular molar teeth with uniform reduction of 1.2mm axially and 1.5mm occlusally. The intaglio surface of all copings were subjected to conditioning: etched using 5% hydrofluoric acid followed by the application of silane coupling agent (Monobond-S) and the application of Primer (Multilink N Primer) on the surfaces of prepared teeth. The copings were bonded to their corresponding tooth using luting agent (Multilink N). After 24 hours of storage in water at room temperature, specimens were loaded on a universal testing machine with the application of compressive load along the long axis of the specimens at a crosshead speed of 1mm/min until fracture. Fracture load values (N) were recorded and resulted to statistical analysis using Student unpaired‘t’ test. Result: The mean load to failure values (SD) of (Group 1) pressed lithium disilicate copings 2134.17 + 289.72 N were significantly (p<0.05) lower when compared to the mean load to failure values of (Group 2) milled lithium disilicate copings (2399.92 + 285.35 N). Significance: Group 2 demonstrated significantly greater load to failure value as compare to the Group 1 (p<0.05).Though, the load to failure values for milled lithium disilicate is significantly greater than that of pressed lithium disilicate but both of its variants can be effectively utilized for posterior restorations where high masticatory forces are present.

Authors: Singh Dr. Mayank Kumar , Kumar Dr. Vijay , Beri Dr. Yogita
Published: September 2024

India is a very diverse country and is divided into many states and regions. The factors, that originate are most significant for the overall growth process, relate to basic requirements of schooling, availability of food, minimum purchasing power and facilities like safe drinking water, health care infrastructure, better transport and many others to attain true sense of development. The government has to take necessary actions to improve the economic and social status across the nation without any biasness. Besides this the states are marked with wide disparity in socio-economic development. Various policies have been floated time and again to reduce these regional disparities. But the ongoing economic growth had proved to be a huge stumbling block in the reform process. However, recent outburst against inequality in developed countries, which followed the global financial crisis, has put the economic disparity at the forefront in economic debate worldwide. Further, India as a republic being 75 years old has seen both good times and periods of turbulence. These years have seen the development of a lively democracy and society where Indians have achieved excellence in the various fields. But the comparative performance of individual states has become one of most important areas of research. Given the regional disparities in India, a study of Indian states is important if the country has to develop economically in a balanced way. This study relates to an analysis of the social and economic indicators in the process of inter-regional disparities in India.

Published: September 2024

The study focuses on optimizing molybdenum extraction using N-(2-hydroxybenzylidene) aniline (HAS) through ultrasonic-assisted and conventional methods. Ultrasonic-assisted extraction reached equilibrium in just 15 seconds, compared to the 15 minutes required by conventional extraction. The research explored the influence of various factors, including extraction time, acid concentration, and molybdenum concentration, to maximize process efficiency. Advanced mathematical models, represented by polynomial equations, were developed for both extraction methods. These equations allow for the optimization of the extraction processes without the need for extensive experimental work, providing a powerful tool for predicting optimal conditions. The ultrasonic-assisted extraction showed its highest efficiency under conditions of 15 seconds, 0.01 M acid concentration, 0.02 M HAS, and 0.01 M molybdenum concentration. Meanwhile, the conventional method achieved optimal results with 15 minutes, 1 M acid concentration, 0.1 M HAS, and 0.01 M molybdenum concentration. The polynomial models derived from this study offer a framework for optimizing the extraction process, significantly reducing the need for time-consuming and resource-intensive experiments. The study highlights the significant advantages of ultrasonic-assisted extraction in terms of both efficiency and time savings. By providing a means to optimize extraction processes through mathematical modeling, this research contributes to advancements in the field of molybdenum extraction and establishes a foundation for further innovation.

A dynamic frictionless contact problem between an elasto-visco-plastic body and a deformable obstacle is numerically studied in this paper. The contact is modeled using the normal compliance contact condition involving adhesion effect of contact surfaces and the thermo-elasto-visco-plastic constitutive law is employed to simulate the thermal effects. The adhesion of the contact surfaces is considered and is modeled with a surface variable, the bonding field, whose evolution is described by a first order differential equation. We provide variational formulation which can be put into a general model of system defined by a second order evolution equality, a first order evolution equation and a first order differential equation. The existence and the uniqueness of the weak solution were established. The proofs are based on evolution equations with monotone operators, differential equations and fixed point theorem. The applied approach leads to a system involving variational equalities and we focuse on the study of fully discrete approximation scheme where both the spatial and temporal variables are discretized. The finite difference method and finite element method are popular numerical methods to discretize problems involving ordinary and partial differential equations. In this work, we will use the first-order finite differences to approximate time derivatives. Moreover, our discussion will be limited to the case of uniform partitions of the time interval and we will use the finite elements for spatial discretizations of variational equalities. For a numerical scheme, we prove the existence and uniqueness of the solutions, and derive optimal order error estimates under certain regularity assumption on the solution of the continuous problem. The additional assumptions on the solution regularity are needed for optimal order error estimates and may not always be valid. Nevertheless, weaker solution regularity assumptions can be used to derive error estimates with lower convergence orders.

The date palm filler has been used as reinforcing filler for Vinyl ester resin (VER) in order to obtain VER/ date palm materials biocomposites. Different loadings of date palm (1 to 5 phr – parts per hundred parts of resin) with a homogeneous particle size having an average diameter of 125µm were added to the VER. These biocomposites were produced by a contact molding process. The results of the investigation revealed that the increase in stress and strain at break with the increase in filler content. The increase in impact resistance up to a filler content of 2phr, for vinyl ester resin of date palm filler biocomposites. In addition, the density of date palm filler induced significant variations in the density of the resin and made it possible to develop biocomposites with densities close to that of the matrix because for the lower concentrations the DP filler are well dispersed into the resin, but entanglements are evidenced when the filler content increases .This study concluded that the date palm filler enhances the properties of composites, a good correlation was observed between the results of the mechanical tests and the physical analysis revealing that the biocomposite obtained has good mechanical strength and lightness.

In our research, we explored how effective it is to use Panicum maximum meal (PMM) in place of fish meal for young Nile tilapia's food. We formulated five different meals that all had the same levels of protein and energy but varied in how much PMM they contained, replacing 0, 25, 50, 75, or 100% of the fish meal protein. For 75 days, we fed these specially prepared meals to young fish (each meal was given to 30 fish starting with an average weight of about 10.2 grams). We looked into how this change affected their growth, how well they used the food, their body makeup, and how well they could digest the nutrients. Compared to the usual fish meal diet, replacing half of the fish meal with PMM didn't negatively impact their growth or how efficiently they turned food into body mass, even though their ability to digest solid food components went down significantly. Fish that ate the diet with the most Corn Gluten Meal (CGM) had too much triglyceride in their blood, and any diet with more than half CGM led to too much cholesterol. Examining the fish that were given a diet with 50% CGM, we noticed they retained more protein and less fat in their bodies. A mathematical model suggested that the optimal growth rate for young Nile tilapia occurs when their diet includes up to a 25% substitution of PMM. Our study shows that CGM can effectively replace up to half of the protein from fish meal in Nile tilapia diets.

Terms such as sustainability and spatial intelligence prevail in the debate on urbanism in Algeria. These indeed reflect a wish to fall in line with international trends in urban development; however, there is also an important gap between what is proclaimed and what is actually being done. This gap becomes most evident during the transition from planning to actual construction, where the objective often shifts towards simply maximizing the number of housing units. The following section details this disconnection, focusing on the cases of planned new cities and, more particularly, the case of Ali Mendjeli. Based on a mix of field observation and bibliographic analysis, we discuss the difficulty in bringing together project stakeholders and the causes that have led to the divergence from expected urban goals. It will also underscore the deficit that characterizes or exists between the principles defining urban development in Algeria and the actual realities of spatial production, which can give an indication of the shortcomings of current planning practice.

Radiation oncology is a specialized medical field that employs various forms of radiation therapy to treat cancer and other diseases. Decision-making in this domain often involves intricate considerations. This paper investigates applying natural language processing (NLP) techniques for classifying clinical text data to recommend the appropriate radiation therapy modality proton therapy or photon therapy. We use the Clinical Text Classification subset of the ROND database, which consists of only 100 manually annotated cancer cases. We start by pre-processing the text data, extracting TF-IDF features, and applying random oversampling to handle the class imbalance issue. We train and evaluate several machine learning models, including support vector machines (SVM), random forest, decision trees, and naive Bayes on this textual data alone. The SVM model achieved the highest accuracy of 95% after oversampling. To enhance interpretability, we apply SHAP values method which provide  insights into which features are most important for the model's predictions towards recommending  therapy  and how they impact those predictions, which  be crucial for understanding and interpreting  machine learning model.

Accurate and efficient detection of hotspots in photovoltaic (PV) panels is paramount for guiding maintenance decisions, enhancing power generation, and ensuring the safety and stability of power stations. In this context, this study applies the Real-Time Detection Transformer (RT-DETR) for the real-time identification of hotspots on PV panels to improve their performance. The use of RT-DETR eliminates the need for traditional post-processing methods like Non-Maximum Suppression (NMS), leading to faster and more accurate detection. A comparative analysis reveals that RT-DETR stands out with zero postprocessing time, whereas YOLO v8 requires over 1.0 ms for similar image analysis tasks. Notably, RT-DETR achieves a higher mean Average Precision (mAP) of 0.802, compared to YOLO v8-l's 0.673, despite the latter having more parameters. This points to RT-DETR's superior efficiency in both speed and accuracy. Additionally, RT-DETR's F1 score of 88% further demonstrates its precision, surpassing that of YOLO v8-l, while maintaining a high frame rate. These results confirm RT-DETR as an effective tool for real-time hotspot detection, suitable for operation on low-power devices such as drones and infrared-equipped smartphones, offering a practical solution for areas with limited resources. The study showcases the potential of RT-DETR in enabling rapid and accurate hotspot detection in PV panels, a significant step forward in photovoltaic technology management.

Currently, wireless communication systems are found everywhere and in large numbers, which increases the amount of radio frequency (RF) signals scattered in the air day by day, which indicates the need to exploit this wasted energy. Energy recovery is one of the solutions to solve this problem which relies on the system called "Rectenna" or rectifier antenna to transform this energy (RF) into useful continuous energy. This recovered energy will be stored or reused to power various low-consumption electronic objects such as sensors, RFID equipment, or other objects that will be installed and used in very large numbers, especially with the implementation of the 5G mobile network around the world. The objective of our work is the study, the simulation and finally the realization of a rectenna system, for the recovery of the signals of the 5G mobile network, in the frequency band between [3.4 – 3.8 GHz], and to try to increase the efficiency of the rectenna by the realization of two types of antennas.
