Abstract
Requirements elicitation is the way toward looking for, revealing, getting, and describing requirements for computer-based systems. It is by and large comprehended that requirements are inspired instead of just drawn together. This suggests there are discoveries, growth, and advanced components of the elicitation procedure. Requirements elicitation is a complex procedure, including various exercises with a collection of available systems, methodologies, and instruments for completing them. The paper introduces a thorough study of the essential parts of the strategies, methodologies, and instruments for requirements elicitation, and inspect the ebb and flow issues, pattern and difficulties looked by analyst and professional in the field. ART SCENE is a tool-supported contextual method for requirements elicitation and is created to gather It uses important aspects of other requirements elicitation techniques like contextual inquiry and scenario-based techniques.

Abstract
Despite substantial progress in recent years, ample therapeutic challenges remain in the treatment of the various diseases. Addressing these challenges requires recognition of pristine classes of drugs and development of non invasive and lucrative methods to select the most appropriate therapeutic option for the disease. The present study discusses the drug property of a natural bioactive compounds contained in Zea mays and aims to establish the active principles of bioactivity The present study investigates the renoprotective properties of a natural non-protein compound pelargonidin-3-glucoside confined in Zea mays that inhibits Angiotensin-I Converting Enzyme. The compounds to be explored as better inhibitors with respect to binding of various drugs like Perindopril available in market and the interactions responsible for the bioactivity of the compound have been discussed using computational methods.

Abstract
A composite of Multiwalled Carbon Nanotubes (MWCNTs) and polyaniline (PAni) was synthesized by in situ oxidative polymerization of aniline monomers on poly (sodium 4-styrenesulfonate) (PSS) dispersed MWCNTs to produce coaxial structures of MWCNT-PAni composite. The structural, morphological, thermal, surface, and capacitive properties of the composite were analyzed. Scanning electron microscopy images of the composite revealed nanofibrous structure. Infrared spectrum showed slight shifts for several bands of the composite from the bands of PAni to suggest that the MWCNTs have strong attractive interactions with the PAni backbone. The composite was fabricated onto a graphite electrode and the fabricated electrode was characterized using cyclic voltammetry. The fabricated electrode exhibited specific capacitance fig 1, and the value retained 82.5% after 800 cycles. Owing to the good capacitance behavior and cycling stability, the synthesized composite holds promise for energy storage devices like supercapacitors.

Abstract
Adsorption of hydrogen on certain metals to form a reversible metal hydride has been known to be one of the most compact and safe methods of storing and immobilizing hydrogen gas and its isotopes. Dynamic thermal analysis of a uranium-based getter bed for storage of upto 50 gm hydrogen has been performed in this work. The storage bed has been considered as a pseudo-homogeneous batch reactor with an initial charge of hydrogen and uranium. The vessel dimensions have been assumed similar to the metal alloy canisters available commercially for hydrogen storage. Both heating and cooling systems have been considered available for the beds. The model equations consist of a system of ordinary differential equations and constitutive laws. Variation of bed and coolant temperature, gas pressure and other vessel scale parameters with time, while incorporating particle level transport phenomena and their effects, has been evaluated through a simplified analysis. Effect of temperature dependent cooling and heating has also been investigated. The model enables fast and realistic estimates of getter bed performance under different hydriding conditions with emphasis on the total hydriding time.
