Volumetric shrinkage critical state induced by desiccation of compacted earth treated and improved with Rice Husk Ash (RHA) and utilized as pavement foundation has been investigated in the laboratory. Ground and soil improvement with the use of rice husk ash has contributed in the management of solid waste in the developing countries where rice production is a common occupation with its attendant solid waste generation. However, the use of biomass-based binders like RHA has reduced the rate at which oxides of carbon are released into the atmosphere, which contribute to greenhouse emission effects. This exercise is an environmentally conscious procedure that keeps the environment safe from the hazards of carbon and its oxides. the preliminary investigation on the test soil showed that it is classified as an A-7-6 soil group according to AASHTO classification. The index properties showed that the soil was highly plastic with high clay content.

Software as a service (SaaS) is a service model of cloud computing by that we can deliver software system applications and use those applications running on the cloud. It is a software distribution model in which programs are managed by a third-party vendor and made accessible over the web to clients. In SaaS, there’s no earlier payment or investment in servers, software system authorizing, and database. We tend to pay as per usage and use it with an online association. SaaS systems are a service-centric cloud computing conveyance model utilized as an IT foundation that is multi-tenant design used to give rich user experience with the necessary set of features that the cloud client needs. A detailed review of the SaaS Architecture is studied together with its Security Issues and inferences are drawn for the same.
