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 con- crete by replacing it with supplementary cementitious materials. Geopolymer concrete is one of those potential candidates for alternative cementitious mate- rials. In today’s world, the production of Construction and Demolition (C&D) wastes has been increased worldwide which finds no suitable disposal and can- not 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.

Increasing fuel prices and emission norms have favoured the automobile man- ufactures to 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 attempt has been made in this work to develop natural fiber hybrid composites with natural and synthetic fibers to address the issue of harm to the environment and energy spent on recycling. In this work the flexural, compres- sion, interlaminar shear stress and low velocity impact properties of natural fiber hybrid composite reinforced with carbon +E-glass intra plies, unidirec- tional sunn hemp mat interplies and nano silica particles are investigated for possible application in automobiles. It is found that the addition of nano silica particles enhances the flexural, compression, interlaminar shear strength and low velocity impact properties of the composite.

The disease dengue has created panic in the minds of men and women of this time. Now a day the menacing of dengue has spread from town areas to rural areas. It affects heavily works on body organs and leads to the final state of death. It works for some years on human organs even after coming round from it. It exists in the human body.This disease is not confined now in the congested town area only, but it has broken out in full swing in the rural area. We aim is to identify the factors which are the causes of the origin of dengue and its spread over society at such a large scale. It is also our aim to find the areas of soci- ety; on which consistent endeavor will help to confine in or diminish its effect in the 0- level. Information is collected on at random survey basis, especially from peoples of dengue affected area by Questionnaire Method. Intelligence is also gathered from hospital and Internet to collect data which help to indi- cate factors performed heavily in which situation of Society.

A reliable method for observing the performance of various systems in a student-designed formula car or All-terrain Vehicle (ATV) is quite expensive, and choices are seemed to be bounded. This paper proposes a lightweight, low power consumption and most affordable system which can collect data from various sensors placed in student formula vehicles and send it to a pit stop  or ground station. We have attached multiple sensors to collect data which includes temperature from brake discs, engine, cockpit, RPM of Shaft, Load exerted by driver on brake pedals, and steering angle. An onboard microcon- troller is programmed to collect and transmit data via the LoRa transceiver. At the ground point, a microcontroller with the same LoRa module tuned as the receiver is programmed to receive the data and display it to the crew. This data can be used to analyse the performance of vehicles in test conditions and compare them to design data.

To realize productivity of delaying the existence over sensor networks several plans hold been proposed. Among this plan, a bunching convention is a won- derful approach up to expectation drags out the existence on an organization. Notwithstanding, in applying that technique, a few hubs burn-through energy superfluously so a result over a local weather whereby the gathered records on the sensor hubs effectively covers. In that paper, we endorse a Clustered Multi- hop Routing Algorithm as decreases superfluous facts transmission amongst hubs by means of but the duplication of information. This strategy forestalls data misfortune added respecting by means of connect disappointment prob- lem then consequently the records is gathered dependably. As indicated via the consequences on the present examination, our approach lessens the electricity utilization, expands the transmission proficiency, then delays community quick so contrasted with the cutting-edge bunching strategies.

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.
