Abstract-The gravity model to the blood supply chain is a conceptual framework that seeks to explain and optimize the distribution of blood products within a healthcare system. It is useful when identifying suitable geographical location within arrange. It is also used to find location that minimizes the cost of transporting raw material from the supplier and finished goods to the markets served. This model also assumes that the transportation cost grows linearly with the quantity shipped. All distances are calculated as the geometric distance between two points on the plane. Using a numerical example, the applicability of the proposed network is analyzed.

Abstract-This paper presents a solution to the inefficiencies of traditional manual attendance systems by proposing a face recognition-based attendance system. project aims to enhance the manual attendance process by using a mobile platform and face recognition technology. The design consists of three main modules: inputting attendance information, signing in with facial recognition, and maintaining attendance records. It begins by explaining the principles of face detection and classification, followed by an analysis of how to build a face recognition classifier. The system is then implemented on an Android platform, allowing for practical use in workplaces.

Abstract-Manufacturing green nanoparticles is a safe, secure, and promising technique. In the current study, piper dravidii leaves extract was used to prepare iron oxide nanoparticles (Fe2O3-NPs) and cobalt oxide nanoparticles (CoO-NPs). UV-visible spectroscopy, scanning electron microscopy (SEM), dynamic light scattering (DLS), vibrating sample magnetometer (VSM), and differential scanning calorimetry (DSC) were used to evaluate the produced Fe2O3-NPs and CoO-NPs. The surface plasmon resonance effect was used to validate the synthesis of FeONPs. FeONPs have an average particle size of about 163.5 nm, a polydispersity index of 0.091, and a zeta potential of -13.8 mV, according to dynamic light scattering (DLS). At 176.91°C, differential scanning calorimetry (DSC) revealed an endothermic peak. With a magnetization value of 3.483 emu/g at ambient temperature, iron nanoparticles were shown to have superparamagnetic characteristics by the Vibrating Sample Magnetometer (VSM) examination, suggesting that they might be used in a magnetically targeted medication delivery system. It has been shown that this biosynthetic method is economical, environmentally benign, and has a lot of potential for use in biomedical research.
