More so, the techniques of convolution and subordination are embraced in the definition of our set of functions. Some of our investigations include the coefficient inequality, radii problems, growth, distortion, closure and inclusion properties.

Some earlier known results are special cases of results established for the new subclass defined.

Initial coefficient bounds and Fekete-Szego estimates for functions belonging to this class are obtained. Furthermore, upon varying the involving parameters in our main results, a number of known and new results are stated as corollaries.

Producing documents using computer-supported methods has become common practice in the institution but the management of documents is still done with manual methods. It is also worth noting that the increased volume of document production and distribution through e-mail systems and workstation-based file managers has aggravated problems in document security, control, tracking, and retrieval. In this work, a secured cloud-based electronic document management system was designed (SECEDOMAS). The system consists of three processes, namely: The document entry process, Electronic document management system (EDMS), and Document retrieval and sharing process The system was implemented using HTML, CSS, JavaScript, Laravel (PHP framework), and MySQL.

In particular, necessary and sufficient conditions for the function  to belong to the subclass  is established. Additionally, we provide the ð›…-neighborhood properties for the function  by making use of the necessary and sufficient conditions. The results obtained are new geometric properties for the subclass Â
