After China, India has the world’s largest MSMEs (Micro, Small, and Medium Enterprises). According to government estimates, the country has roughly
63.05 million small enterprises, 0.33 million small businesses, and around 5,000 major businesses. The Micro, Small, and Medium Enterprises (MSME) sector of the Indian economy is a vibrant and dynamic sector. It adds to the country’s economic and social development. MSMEs, second only to farming, encourage enterprise and create the most job vacancies at a relatively cheap capital cost. MSMEs now operate in almost every key sector of the Indian economy, including food processing, textiles and apparel, agricultural data sources, leather and cowhide stuff, sports merchandise, plastic items, electro- restorative equipment, and computer software, to name a few. With their devo- tion to modern yield, fares, business, and creation for the Indian and global markets, SMEs play a critical role in the Indian economy. The focus of this study is on existing advertising mediums for SMEs in the administration’s area, as well as the scope of internet marketing. With the passage of time, internet media has grown in importance in marketing, and it may be the ideal vehicle for SMEs to achieve success in marketing.

There is a continuous demand and burning of limited fossil fuel prompted the urgent need to develop renewable, abundant, and clean energy source. There- fore, for solving the energy crisis, the production of green hydrogen by elec- trochemical water splitting plays a vital role in achieving this goal. But, this electrochemical energy production process is kinetically sluggish due to multi- electron transfer reactions Therefore, the development of an efficient inexpen- sive catalyst towards OER have been required to accelerate the rate of oxy- gen evolution. We effectively designed and synthesized sheet-like morphology of lanthanum doped cobalt selenate through the one-pot hydrothermal route. The synthesized material is confirmed by different techniques. Herein prepared sheet-like La doped CoSe2O5 material is employed as an efficient electrocata- lyst towards OER in alkaline medium. This electrocatalyst show the low Over- potential and the low the Tafel slop value. Also successfully doped with the rare earth metal it show the large exchange current density and the active sites.

Increasing fuel prices and emission norms have favoured the automobile manufactures the use of lightweight materials. Land fill regulations imposed by many environmental governing agencies encourage the use of products which will decompose easily or which will require lesser energy for recycling. In this scenario, an effort has been made to build natural fibre hybrid composites combining natural and synthetic fibres to solve the problems of environmental impact and energy wasted on recycling in this study. In this work the flexural, compression, interlaminar shear stress and low velocity impact properties of composites reinforced with plies containing carbon fibres in the weft direction and E-glass fibres in the warp direction, parallel oriented sunn hemp mats and 40 µ SiO2 particles are investigated for possible application in automobiles. It is observed that the reinforcement of the composite with 40 µ SiO2 particles enhances the flexural, compression, interlaminar shear strength and low velocity impact properties of the composite.

Cement concrete and other cement-based composites find wide application in the construction industry. The manufacturing of cement releases a large amount of CO2, so the use of cement has become a major area of environmental concern. Attempts have been made to minimize the quantity of cement in concrete by replacing it with supplementary cementitious materials. Geopolymer concrete is one of those potential candidates for alternative cementitious materials. In today’s world, the production of Construction and Demolition (C&D) wastes has been increased worldwide which finds no suitable disposal and cannot be used in ordinary concrete due to potential deterioration of concrete quality. However, C&D waste can be safely used with geopolymer concrete with and without the usage of Supplementary Cementitious Materials (SCMs) and play a major role in improving the strength and durability properties of concrete

In this paper we have proposed a room sanitation robot. The world around us is facing new threats day by day, latest being the corona virus. Social distancing, wearing masks, sanitizing the hands and disinfecting rooms are some precautionary measures to be taken against this deadly virus. Hence our project aims at disinfecting the rooms by deploying robots instead of manpower. Steriloid is a sanitizing robot which can be used to sanitize rooms, pathways, roads etc. It can be controlled in two modes manually or automatically. In the Automatic mode, the robot moves around the room with the help of two ultrasonic sensors. The sensors detect the obstacle while the robot is in motion and control the robot accordingly. In the Manual mode, complete control of the robot is in the user's hands. A mobile application is used to control the robot via a Bluetooth module. So the robot can move to any location. Sanitizer or sanitizing liquid is filled inside a reservoir and a pump is placed inside it. When the robot starts moving, the pump can be turned on from the mobile or manually and it starts sanitizing the room.

Education is continuing its journey since man is on earth. It may be the nature taught man in the yester years, gurukulas in the golden period of many kings, Government Schools and colleges’ post-independence era and convents, international schools, deemed universities in the 21st century, its common objective of all these institutions is to educate the human race. Education is not just reading the books and getting a degree from a University, it is the holistic development of an individual physically, mentally, financially and economically. The aim of education is to bring overall development of an individual and make him today a productive citizen, for tomorrow’s nation. Every country develops its education system to express and promote its unique socio-cultural identity and to meet the growing demand of job and career opportunities. The country has reached a stage in economic and technological progress and efforts must be made to ensure that the fruits of change reach all the sections of the society. The National Education Policy- 1986 focused on common curriculum framework that contains a common core along with other components that are flexible. Child-centric approach is given prominence in elementary education, followed by secondary education giving prominence to girl child education and SC, ST and BC categories of education. The National Education Policy-2020, which is reformed after 34 years, emphasized more on holistic approach with multi-disciplinary courses and students are facilitated with bucket system of choosing subjects of their interest. This paper focuses on the comparative study on the highlighted aspects of NEP of both 1986 and 2020.
