Abstract:
Transferring data across storage types, formats, including computer systems is data migration. It crucial for system installation, upgrading, and consolidation. Due to various business demands, numerous sectors have prioritized it. The ETL procedure is crucial to data warehouse construction. Data is extracted from different operation kinds and loaded into a data warehouse in diverse contexts using numerous technological methods. This method combines data from diverse sources and operation kinds and converts nonstandard data into standard ones. Systems and techniques may analyze an underlying language structure within the source data integration framework to establish logical syntax. The rapid growth of data-driven decision-making in modern enterprises has increased the reliance on Extract, Transform, and Load (ETL) processes and Data Warehousing systems. These components form the backbone of analytical and business intelligence operations by integrating, cleaning, and consolidating data from multiple sources into a unified repository. However, as the volume and complexity of data increase, so do the risks associated with unauthorized access, data leakage, and system vulnerabilities. This paper presents a comprehensive overview of the architecture of ETL and Data Warehousing systems, highlighting the key stages, workflows, and technologies involved. It further examines common security vulnerabilities, including data breaches, insider threats, injection attacks, and configuration weaknesses that compromise data integrity and confidentiality. Finally, the study explores security mechanisms and best practices such as encryption, authentication, access control, auditing, and secure ETL pipeline design to mitigate these threats. The analysis emphasizes the importance of embedding security measures throughout the data lifecycle to ensure trustworthy and resilient data warehousing environments.

Abstract:
This research assess the impacts of marine pollution on the sustainability of ecosystems at Tanga Port, Tanzania, focusing specifically on oil spills, waste and sewage, ballast water discharge, and the efficacy of regulatory frameworks. A mixed-methods approach was utilized, incorporating survey questionnaires distributed to 80 stakeholders, including ship operators, owners, ecologists, and regulatory officials, alongside qualitative interviews to gather experiential insights. The objective of the study was to identify the ecological consequences of pollution, evaluate the impacts of ballast water, and propose strategies for enhancing sustainable marine pollution management in Tanzania. The results indicated that oil spills, waste and sewage, and ballast water discharge are widely regarded as significant threats to marine biodiversity, aquatic habitats, and the stability of the food chain. Analyses of reliability and validity confirmed that the measurement instruments were reliable, while regression analyses revealed that perceptions of oil, sewage, waste pollution, and ballast water impacts were strong and positive predictors of environmental awareness and proactive behaviors. Overall, the model accounted for 55% of the variance in stakeholder engagement (R² = 0.55). Further analysis showed high levels of awareness regarding local (96.25%) and international (90%) safety regulations among vessel operators, with substantial evidence of regular engagement and inspections by regulatory authorities. Nonetheless, deficiencies in enforcement capacity, particularly concerning ballast water treatment and oil spill response infrastructure, persist as critical issues. The study concludes that although Tanzania has achieved significant progress in regulatory compliance and stakeholder awareness, enhanced institutional capacity, investment in infrastructure, and stricter enforcement are crucial.

Abstract:
The study evaluates the effects of digitalization on the efficiency of supply chain functions in the retail sector of Tanzania, specifically focusing on the Azam Bakhresa Group. As technology advances, retail supply chains face increasing demands to incorporate innovations like artificial intelligence, blockchain, the Internet of Things (IoT), and electronic procurement systems, such as TANePS. The research aims to evaluate how these technologies affect supply chain transparency, efficiency, responsiveness, and overall customer satisfaction in the Tanzanian context. Utilizing a descriptive research design and a mixed-methods approach, the study drew data from 80 respondents, including supply chain professionals, IT specialists, procurement officers, and retail managers, through questionnaires and in-depth interviews. The quantitative data were analyzed using descriptive statistics, while qualitative responses were thematically analyzed to provide depth to the numerical findings. Results indicated a strong consensus on the positive impact of digital tools. Over 95% of respondents recognized that emerging technologies enhance supply chain visibility, accountability, and responsiveness.

Abstract:
Background: Dengue Fever is the most geographically widespread arthropod-borne disease. It can present a variety of clinical spectra varying from asymptomatic illness to dengue shock syndrome.
Case Presentation: 42-year-old female patient who has presented with a three-day history of fever and subsequently developed dengue hemorrhagic fever with multi-organ failure. Despite intensive care management, the patient died three days after admission to a tertiary care hospital.
Conclusion: Early recognition of dengue hemorrhagic fever and appropriate management during the critical phase are crucial.

Abstract:
Coral reefs are among the most productive and ecologically important marine ecosystems, yet they are increasingly threatened by climate change and local environmental stressors. Restoration efforts under controlled laboratory conditions provide a valuable approach to support coral growth and resilience.

Abstract:
The research, titled "Design and Analysis of an Aerodynamic Downforce Enhancement Device for a Race Car," focuses on the implementation and optimization of a ducted fan system to actively generate a low-pressure area beneath the car, thereby enhancing aerodynamic downforce. This innovative approach involves the use of two ducted fans strategically positioned to pull air from underneath the car, channeling it through the underside of the rear wing to maximize rear downforce efficiency. The primary objectives of the study were to increase overall downforce, elevate cornering speeds, optimize drag, and enhance safety measures.

Abstract:
This paper explores the potential of using an Oxy-Hydrogen mixture as an alternative fuel extracted from the water, considering the impending depletion of petroleum fuel. The demand for fossil fuel is increasing, but estimates suggest it will be exhausted before the 2060s. If this occurs, all conventional fuel vehicles will become obsolete. Our research primarily focuses on converting existing petrol engines to run on an Oxy-Hydrogen mixture with slight modifications done to the engine. This study encompasses the production of the Oxy-Hydrogen mixture, lubrication of the fuel system, cooling of the electrolysis process, charging of the battery

Abstract:
Small-scale farming operations are significantly dependent on diesel-powered walking tractors, resulting in high fuel consumption, elevated operational costs, and considerable greenhouse gas emissions (Smith et al., 2018). To mitigate these challenges, this research presents the development of a power-assisted solar-powered walking tractor featuring an automatic power transfer mechanism (Wang et al., 2020).

Abstract:
Background: Pharmacovigilance (PV) is the science of detecting, assessing, and preventing adverse drug reactions (ADRs), which are often not fully recognised in pre-marketing clinical trials [85]. Objective: This review analyses the historical development of PV (1848–2025), comparing global milestones with Indian initiatives, and identifies future challenges and opportunities [86].

Abstract:
Male infertility contributes to nearly half of all infertility cases worldwide, with Oligospermia being a common cause. Garbha Sambhava Samagri is a foundational concept in Ayurveda, delineating the essential factors for successful conception and healthy fetal development as Ritu (Fertile Period), Kshetra (uterus), Ambu (Nutrition) and Beeja (Gametes). Beeja are the male and female reproductive elements of Shukra (sperm) and Artava (ovum), which must be unvitiated and of optimal quality for conception. Ayurveda describes low sperm count as Ksheena Shukra or Shukrakshaya, often attributed to Vata and Pitta vitiation.
