The cornea comprises a pool of self-regenerating epithelial cells that are crucial to preserving clarity and visibility. Limbal epithelial stem cells (LESCs), which live in a specialized stem cell niche (SCN), are crucial for the survival of the human corneal epithelium. They live at the bottom of the limbal crypts, in a physically enclosed microenvironment with a number of neighboring niche cells. Scientists also simplified features of these diverse microenvironments for more analysis in situ by designing and recreating features of different SCNs. Recent methods for regenerating the corneal epithelium after serious trauma, including burns and allergic assaults, focus mainly on regenerating the LESCs. Mesenchymal stem cells, which can transform into self-renewing and skeletal tissues, hold immense interest for tissue engineering and innovative medicinal exploration. This review summarizes all types of LESCs, identity and location of the human epithelial stem cells (HESCs), reconstruction of LSCN and artificial stem cells for self-renewal.

Recently, the demand for border crossing has increased massively, with the aim to increase the processing and clearance speed at border crossing points (BCP). The attempt to improve travel convenience, Border Cross Point (BCP) output and national security result in automated border control (ABC) with biometric technology having a majo r effect on the efficiency, and safety of the control processes. The border processing of BCP can be increased by automating biometric recognition and facilitated by clearance procedures. This paper discussed the two structures of an e-gate (ABC) and a prospective benefit of biometrics to the EU border in terms of accuracy, integrity, robustness, and efficiency. Challenges posed by biometrics in border control systems were identified and recommendations such as multimodal systems and smart systems with AI and machine learning were suggested to assist travellers to cross border points faster.

Human life and welfare are utterly dependent on peace. Peace is, thus, vital for the existence and sustainability of humanity. The quest for peace has become a necessity from the origination and existence of humanity. Hence, it has been incumbent on the Church as an institution to be involved in the collaborative pursuit of peace in human society. This paper discusses biblical expositions on peace and how the Church as an institution can ensure peace in human society. This paper is relevant because it makes people aware that the phenomenon of peace has a biblical backing, and hence it is a divine requirement that the Church and humanity in general should do everything possible to ensure and sustain peace in human society. Using texts from the Bible and other secondary data resources from the internet, and published and unpublished literature in the form of books and journal articles, the authors discuss the concept of peace theologically and expound on the role of the Church in ensuring societal peace. This study is necessary because it uncovers what the Bible says about Peace and how the Church, whose operation is centered on the tenets of the Bible, can ensure peace in the society.
