Intelligent Lighting Control System for Street and Landscape Lights Based on ZigBee and GPRS
Get PDFTo address the challenges of high energy consumption, costly maintenance, and inefficient management in traditional urban lighting systems, this study presents the development of the TDFY City Lighting Management System. This intelligent lighting control system is based on a hybrid communication architecture combining ZigBee and GPRS technologies. The system integrates loop and individual lamp control to optimize energy usage and reduce operational costs. By leveraging ZigBee’s wireless mesh network for decentralized lighting unit management and GPRS for remote access and monitoring, the system ensures reliable communication, remote fault detection, and efficient maintenance planning. A key feature of the system is its adaptive dimming functionality, which automatically adjusts lighting based on motion sensor input, thereby enhancing both energy efficiency and lighting performance. Implemented in real-world scenarios such as the Taiyuan Botanical Garden and Taiyuan University of Technology, the system achieved up to 40% energy savings. These results demonstrate the system’s scalability, reliability, and potential to serve as a core component in smart city infrastructure, promoting sustainable, cost-effective urban lighting solutions through advanced energy management. 
Level of Perception and Academic Performance in Technology and Livelihood Education among Grade 7 Students of Saint Paul University Surigao
Get PDFThe purpose of this study was to determine Grade 7 students' perceptions of engagement, meaningfulness, instruction and resources, and their academic performance in Technology and Livelihoods Education 7. The participants were profiled in terms of gender, age and academic achievement. The study analysed 138 Grade 7 students taking TLE7 Exploratory courses. The study used a descriptive survey method and data were collected through an adapted and modified questionnaire. The statistical tools used were (Frequency Count and Percentage Distribution, Mean and Standard Deviation, One-Way Analysis of Variance (ANOVA), and the use of verbal interpretation and qualitative description. The results show that the respondents are mainly female (56.52%), aged 13 (53.62%), and 85-89 (48.55%) as the majority of academic performance in terms of their final grade in TLE. The results show that the majority of the participants have a generally positive perception of Technology and Livelihood Education in terms of engagement, meaningfulness, and teaching and resources. And there is a significant difference in the level of perception of Grade 7 students in Technology and Livelihood Education and their academic performance. This study recommends further research to explore students' perceptions of TLE. To address the gender imbalance in participation, future studies should aim for a more balanced representation. In addition, qualitative research such as interviews with teachers and students, as well as comparisons with other schools, can provide insights into why students find TLE engaging and relevant. Finally, the significant difference in perceptions based on academic achievement warrants further investigation. Analysing existing data and combining it with interviews can help to understand the reasons for this difference. Ultimately, adapting the TLE programme to different learning styles could improve engagement for students of all academic backgrounds. 
A Comprehensive Study on Various Cancer Occurred in Pediatric Unit
Get PDFThis thorough investigation looks at the prevalence, identification, management, and results of different malignancies that happen in pediatric units. Even though it is less common than adult cancer, pediatric cancer still contributes significantly to the morbidity and death of children globally. Many juvenile cancers are the subject of this study; these include lymphomas, brain and central nervous system tumors, leukemia’s, and solid tumors including neuroblastoma, Wilms tumor, rhabdomyosarcoma, osteosarcoma, and Ewing sarcoma respectively. Along with the most recent diagnostic methods, including genetic testing, sophisticated imaging, and laboratory testing, we examine the genetic, environmental, and viral risk factors influencing the development of these diseases. The many treatment modalities including stem cell transplantation, radiation therapy, surgery, chemotherapy, and the newly developed fields of targeted therapy and immunotherapy are covered in detail. The study also discusses the short- and long-term side effects of pediatric cancer treatments, emphasizing how important survivorship and post-treatment care are. The focus is on the psychosocial and educational support that juvenile cancer survivors require in order to enhance their quality of life. Personalized medicine and innovative therapy techniques are the main topics of discussion when it comes to the future orientations and current research trends in pediatric oncology. The goal of this research is to give a thorough understanding of pediatric malignancies, providing knowledge that can guide improved therapeutic procedures and enhance the prognosis of young patients. 
Extraction of Dye from Coconut Husk (Cocos Nucifera) and Its Effect on Cotton Fabric Extract
Get PDFThis study examined the extraction of dye from coconut husk and its effects on colouring of cotton fabric. Three different solvents were used in the extraction process namely methanol, ethanol, and acetone. The ethanol fraction gave the highest yield of extraction ranging from (E3) 40.3%, (E2) 24.3%, (E1) 12.2% over acetone with (A3)37.2%, (A2) 22.5%, (A1) 11.2% and methanol with (M3) 30.3%, (M2) 18.1%, (M1) 9.15% respectively. The extract was found to be slightly acidic as the pH of the dye extracted ranges from (A2) 4.6 to (E3) 50. The dye extracted exhibits exceptional light and wash fastness using allum (aliminium sulfate) as mordant. The dyeing process also involves the interaction between the dye molecules and cotton fabric, illustrating the concept of absorption, adsorption and diffusion which makes it significant. The extracted dye can be used to create unique, sustainable textiles with potential applications in fashion, upholstery and other industries. 
The Impact of the Party’s Foreign Policy (1965–1975) on the Outcome of the Vietnamese Revolution
Get PDFThe Party’s independent and autonomous foreign policy was formed and developed across successive revolutionary periods. During the national democratic revolution (1945–1975), the Party recognised and addressed the challenge of maintaining independence and autonomy in foreign affairs while simultaneously seeking international support and assistance. This approach involved combining national strength with global trends to build a unified force, ultimately leading the Vietnamese revolution to its historic victory in the Spring of 1975, resulting in the liberation of the South, national reunification, and the commencement of a transitional period towards socialism. In the subsequent period of defending independence and initiating reform (1975–1985), the Party’s independent and autonomous foreign policy gradually adapted to both global and domestic changes. Moreover, Party thinking evolved significantly, particularly regarding the relationship between independence, autonomy, and international integration. 
Decorative Symbolism of Islamic Motifs: Aesthetic and Cultural Analysis of Calligraphy in Mughal Textiles
Get PDFOne of the world's most renowned periods of creative and artistic development was the Mughal Empire (1526–1857), when Islamic art flourished and was inspired by indigenous cultures. Among its artistic legacy, Islamic calligraphy on textiles is a vital form of aesthetic expression. This study explores Islamic calligraphy's decorative symbolism and aesthetic dimensions within Mughal-era textiles. Drawing upon historical references and visual analyses, the research examines how calligraphic elements were integrated with traditional Islamic motifs, such as floral and geometric patterns, to reflect cultural, religious, and political ideals. The paper also highlights the unique material techniques, design philosophies, and cross-cultural influences that shaped the visual language of Mughal textiles. By comparing Mughal calligraphic practices with those of other Islamic empires, including the Ottoman and Safavid dynasties, this study provides a comprehensive understanding of the role of calligraphy in textile art. The findings contribute to broader discussions of Islamic art heritage and its continuing influence in contemporary design
Performing Parliament: Executive Scripting, Symbolic Interaction, and the Social Life of Legislation in Sierra Leone
No full textThis article examines the dynamics of parliamentary performance in Sierra Leone’s 4th and 5th Parliaments (2012–2023), focusing on the interplay of formal rules, informal practices, and symbolic performances. Moving beyond frameworks of neopatrimonialism, electoral financing, and corruption, the study explores how executive scripting, ritualized deference, and symbolic acts such as walkouts, silences, and applause structured legislative life. Drawing on theories of symbolic interactionism and informal institutions, it demonstrates how parliamentary behaviour often reflected shadowboxing rather than substantive deliberation, creating an institutional culture marked by distrust, fragile alliances, and ritualized obedience. The analysis highlights the limits of colonial-era procedural legacies when confronted with postcolonial informal logic of loyalty and survival. It argues that Sierra Leone’s parliament functions less as a deliberative policy arena than as a contested stage of performance, where MPs navigate fatalistic outcomes through make-belief practices that signal loyalty, secure survival, yet erode institutional credibility
Renewal of Economic Thinking in Vietnam in the Period 1986 - 1991: From Theoretical Perception to Practical Policy Making
No full textIn the context of complex world developments and the socio-economic crisis in the country, Vietnam faced many difficulties, especially in the economy. Therefore, in the period of 1986 - 1991, the Communist Party of Vietnam abolished the centralized, bureaucratic, subsidized economic mechanism, developed according to the market mechanism under state management, and built a multi-sector commodity economy, in which the state economy played a leading role. Due to the breakthrough innovation in economic thinking, the production and business activities of factories and enterprises were put into operation with high productivity and efficiency, meeting the consumption needs of the people, making the distribution and circulation of goods convenient. People's lives were significantly improved
Response of Rapeseed Crop to Supplemental Phosphorus Levels and Plant Distribution within the Field
No full textA field experiment was conducted in the Al-Rumaitha district area, 37 km north of Al-Muthanna Governorate, during the winter season of 2021-2022, with the aim of studying the effect of plant distribution systems within the field and the addition of supplementary phosphate fertilization on the growth and yield of rapeseed (Pactol variety). A complete randomized block design was used using the split-plot method and with four replicates. The cultivation systems included the main-plotss and the supplementary addition of phosphorus to the sub-plots. The results indicated the effect of the third supplementary addition of phosphorus on total branches number, mustards number per plant, grains number per mustard, while the first addition treatment outperformed in leaf area, and the fourth addition treatment gave the highest average in plant height. The 1000 grains weight had no significant effect. Plant distribution systems affected growth and yield traits, where the third plant distribution system gave the highest leaf area, the first system outperformed 1000 grains weight, while the plant distribution systems did not affect the other traits significantly. The interaction between the third addition treatment and the third plant distribution system achieved the highest average number of grains per mustard
Dynamics of Environmental Conditions and Persistence of Malaria, a Tropical Disease in the City of Koudougou in Burkina Faso
No full textMalaria is one of the oldest diseases in human history. The first scientific knowledge about this epidemic dates back to Hippocrates (5thcentury BC). The discovery of Plasmodium, the parasite responsible for malaria, by Alphonse Laveran in 1880 opened up a new and more dynamic front in the fight against this disease. However, socio-environmental factors were largely overlooked in the fight against the disease. This study therefore focuses on the socio-environmental determinants causing the emergence and persistence of malaria in the city of Koudougou. Very few studies have examined the relationship between malaria and the urban environment in medium-sized cities in Burkina Faso. The methodological approach of this research is based on a literature review and field surveys of 372 households in three (03) sectors of the city of Koudougou. The processing method used is essentially based on descriptive statistical analyses. This work shows that socio-environmental factors maintain the morbidity of this disease in the city of Koudougou, based on the results of the surveys compared with data from local health facilities. Indeed, 30% of those surveyed live less than 500 metres from a waste dump and 24% of the same respondents acknowledge the existence of a water source or flood zone near their homes
