Abstract-A big challenge in the urban cities is that of waste management as there is a rapid growth in the rate of urbanization and thus there is a need of sustainable urban development plans. As the concept of smart cities is very much trending these days and the smart cities cannot be complete without smart waste management system. There needs to be system that gives prior information of the filling of the bin that alerts the municipality so that they can clean the bin on time and safeguard the environment. To avoid all such situations we intend to propose a solution for this problem "Smart Garbage Bin", which will alarm and inform the authorized person when the garbage bin is about to fill. Then message will be send to the authorized person to collect the garbage from the particular area. The authorized person will sends the message from his web application to the garbage collectors by sending a SMS .This system maintain a dry waste and a wet waste separately. This will help to reduce the overflow of the garbage bin and thus keeping the environment clean.

In numerous aspects of digital marketing usage, India is among the top two countries in the world. Almost all businesses currently use digital marketing. Thousands of start-up businesses with new ideas strive to break into the corporate sector every year. Unless they have a good marketing plan, start-ups and SMEs will be unable to compete with established and lucrative organisations. One of the leading causes of business failure is a lack of a comprehensive digital marketing strategy. However, not all of the tools available to a digital marketer are equally productive. The barrier between the “haves” and the “have nots” is narrowing as technology interventions become more widely available. Some digital marketing methods succeed, while others fail. In view of the importance of digital marketing usage in India, this paper provides a framework based on Diffusion of Innovation (DOI). It also makes use of Technology-Organization-Environment (TOE) theory for obtaining conceptual framework. Two constructs are used by the researcher to frame the conceptual framework: technical and environmental. The current study employs an exploratory research design in which the study attempts to investigate the level of awareness of digital marketing tools as well as the factors influencing the adoption of digital marketing by start-ups and Small and Medium Enterprises (SMEs) using a positivist research philosophical stand. For statistical interpretation, the study used the SPSS tool and Smart PLS. The current study’s population consists of owners and managers of manufacturing and service-based start-ups and SMEs operating in Karnataka’s North Karnataka area. To collect answers from the audience, this study employs a mixed methodological technique. Smart PLS - Structural Equational Modelling (SEM) is used to validate relevant hypotheses. For factor grouping and identification, the SPSS programme was employed. To obtain the SEM model, the discovered components were iterated using Smart PLS software.

Background- The goal of the whole study was to examine the formulation of tablets containing sustained-release metoprolol succinate employing Aegle marmelose (Bael), a member of the Rutaceae family, as the matrix forming polymer. Excipients play an important function in enhancing a formulation's quality. Result-The use of aegle marmelose polymers in pharmacy is similar to that of synthetic polymers, which have a wide range of potential applications in innovative drug delivery systems as matrix formers. Due to the fact that these polysaccharide gums are naturally plentiful, biocompatible, biodegradable, and non-immunogenic, and because they boost the economy by giving people access to low-cost formulations made using locally accessible materials. In order to get the desired features of components for drug delivery systems, they can also be altered in a variety of ways, which makes them competitive with the synthetic additives that are now available. The formulation of metoprolol succinate matrix tablets uses the fruits of the Aegle marmelosto as a binder. The metoprolol succinate tablet was created using a 32 factorial design (F1 to F9), and from that F6 batch, tablets were tested for weight variation, hardness, friability, drug content, drug release research, stability study, solubility study, swelling property, and drug excipients compatibility.. Conclusion-Metoprolol succinate tablets that have been manufactured and tested for stability reveal no major alterations, making aegel marmalos polysaccharide a more suitable natural binder than synthetic one Additionally, the goal of the study was to determine the potential of natural polysaccharide.
