In today's software industry, technological prowess and ever-evolving customer requirements have led to more complex software demands. Agile based software development is increasingly being adopted by the software practitioners as it assures early software development and high quality software products. Also, it offers responsiveness to changes in user requirements, providing for their quick absorption during software development. In this paper, we elaborate the significance, benefits and increasing adoption of Agile methodologies in context of today's complex and evolving software demands. The main objective of this paper is to conduct an empirical study into the choice among the most popular Agile methodologies, Scrum, Extreme Programming and Kanban. Further, this paper provides for a comparative analysis among various agile software development methodologies. Our survey results reveal higher adoption of Scrum based development in present-day software industry as compared to Extreme Programming and Kanban methodologies.

: Nanomaterials have applications in almost every field and among them, green nanomaterials have various biological applications. Green nanomaterials are specifically useful for drug and DNA delivery applications. Considering that cellulose is the most abundant and easily available biomolecules, and it has been used for preparing greener cellulose nanomaterials. Cellulosic nanowhiskers are a cost-effective and green alternative to chemical non-viral gene delivery systems. Cellulose nanowhiskers are commonly extracted from plant sources, and they are generally prepared by sulfuric and hydrochloric acid hydrolysis of plant cellulose. In this review, the topic of cellulose nanowhiskers as green biocompatible materials for gene and drug delivery is discussed with several practical examples.

AbstractDistributed computing architecture has been around for a while, but not all of its benefits could be leveraged due to issues such as inter-operability, industry standards and cost efficiency that could provide agility and transparency to the business process integration. Web services offer a cross platform solution that provides a wrapper around any business object and exposes it over the Internet as service. Web services typically work outside of private networks, offering developers a non-proprietary route to their solutions. The growth of this technology is imminent; however, there are various factors that could impact its adoption rate. This paper provides an in-depth analysis of various factors that could affect adoption rate of this new technology by the industry. Various advantages, pitfalls and future implications of this technology are considered with reference to a practitioner survey conducted to establish the main concerns effecting adoption rate of Web services.
