Abstract The increased use of digital technologies in public administration has created new means for controlling the execution of administrative contracts. Of all these digital technologies, global positioning system (GPS) tracking has been recognized as a means to ascertain contractors’ observance of contract terms regarding dates and to identify possible delays in the execution of contractual obligations. The legal validity of GPS data has also posed a number of issues, including its authenticity, its accuracy, and the protection of contractors against false digital evidence. This research focuses on the legal implications of using GPS data as a basis for computing delay penalty calculations in administrative contracts. It also analyzes the possibility of using GPS data as reliable digital evidence to ascertain the contractor’s location and time of arrival and the legitimate use of the data to justify the authority of the administration to impose financial penalties on the contractor. This research is premised on the hypothesis that while GPS data can be used to improve administrative efficiency and accuracy in monitoring contractual obligations, its use must be accompanied by legal and technical verification to ensure the integrity and reliability of the data used. The importance of the stipulations made in contracts with regard to the use of GPS technology is also highlighted by the study, along with the need to ensure the availability of technology and procedural safeguards such as verification of the data, transparency of the data processing, and the availability of an opportunity for the contractors to dispute the data. The significance of providing an opportunity to dispute possible inaccuracies before imposing financial sanctions is also highlighted, thereby maintaining the concepts of fairness and due process through the judiciary in the field of administrative law. Ultimately, the research seeks to provide a balanced framework of law that addresses the interests of the administration in the effective supervision of the contract, as well as the right of the contractor to procedural protection. The establishment of effective digital verification mechanisms would enable the administration to make effective use of the GPS data while protecting the rights of the contractors.
The development of sustainable, plant-derived antimicrobial polymeric biomaterials is increasingly important for managing infections associated with wound environments, particularly in the context of rising antimicrobial resistance. In this study, low-cost bacterial cellulose (BC) was produced using waste-derived fruit media and subsequently modified with Croton confertus leaf extract (CE) through an ex situ infusion process to obtain bioactive BC-CE composites. The physicochemical structure of the composites was characterized using FE-SEM and FTIR analyses, which confirmed successful incorporation of phytochemicals into the nanofibrillar cellulose matrix and demonstrated reduced porosity, enhanced hydrogen-bonding interactions, and improved microstructural stability. BC-CE films revealed better moisture-retention capabilities than pure BC, maintaining structural stability for repeated swelling/drying cycles. Antibacterial performance indicated clear inhibition zones (1.28 cm for Staphylococcus aureus and 1.11 cm for Escherichia coli) and substantial growth containment, with 46% and 36% reductions in bacterial proliferation, respectively. In vivo wound-healing experiments further demonstrated accelerated epithelial regeneration and reduced inflammation in BC-CE-treated wounds compared to BC control dressings. Collectively, these findings highlight the synergistic benefits of integrating plant-derived phytochemicals within a sustainable BC platform, providing a cost-effective and biocompatible polymeric biomaterial with promising potential for next-generation wound-care applications with antimicrobial functionality.
Griseofulvin, a common antifungal, suffers from poor solubility and skin penetration, limiting its topical efficacy. The main purpose of the study is to develop and characterize a griseofulvin-loaded transfersomal gel to enhance topical delivery and sustain antifungal activity. The transfersomes were prepared by thin-film hydration with varying ratios of lecithin and Tween 80 and evaluated for vesicle size, morphology, and entrapment efficiency (EE). The optimized formulation (GRF7) had the highest EE (98.02 ± 0.55
In this research work, the new subclass Upsilon=,a,L,m,phi(qe) of bi-univalent functions related to Fibonacci numbers Sigma is presented. Our primary contributions to this for functions in this particular subclass, the study entails placing restrictions on the absolute values of the second coefficient |a2| and the third coefficient |a3|. Furthermore, Fekete-Szeg & ouml; functional problems are solved by us. In addition, our analysis shows interesting results from the particular parameter values applied in our primary conclusions.
The growing importance of digital technologies in industrial environments has increased academic and managerial interest in understanding how Internet of Things (IoT) adoption can improve sustainability performance. Industrial firms are under rising pressure to enhance resource efficiency, reduce environmental impact, and support long-term sustainable operations. Despite the expanding relevance of IoT in industrial transformation, limited empirical research has examined its effect on sustainability performance through renewable energy and under the influence of green logistics capability. Grounded in the Resource-Based View, this study investigates the impact of IoT adoption on sustainability performance in the industrial sector, while examining the mediating role of renewable energy and the moderating role of green logistics capability. A quantitative approach was adopted, and data were collected from industrial firms using a structured questionnaire. Partial Least Squares Structural Equation Modeling was employed to test the proposed hypotheses. The findings reveal that IoT adoption has a significant positive effect on sustainability performance. Renewable energy was found to mediate this relationship, while green logistics capability strengthened the positive influence of IoT adoption on sustainability performance. The study contributes to the literature by presenting an integrated model that connects digital adoption, renewable energy, green logistics capability, and sustainability performance.
