In the current situation, we frequently observe that the trash cans or dust cans that are located in public spaces in cities are overflowing due to an increase in the amount of waste produced each day. We propose to construct a "Smart Waste Management System utilising IoT" to prevent this because it leads to unclean conditions for people and produces a terrible stench in the surrounding area, which spreads some deadly diseases & human illness. In the proposed system, there are numerous trash cans scattered throughout the city or campus. Each trash can has a low-cost embedded device that tracks the level of the trash cans, and each one will also have a unique ID that makes it simple to determine which trash can is full. The device will broadcast the level and the supplied unique ID when the level hits the threshold limit. The concerned authorities can view these facts online from their location and take fast action to clean the trash cans.

Cosmetics have fascinated the human race for ages. Cosmetics have been found to benefit in several ways such as enhancing appearance, protection, cleansing etc. If fortified with the benefit of herbal ingredients, these personal care products have proven to be a boon for many. The current study involves the formulation of seven shampoos using different herbal extracts and their comparative investigation for physicochemical and performance characteristics. Various herbal extracts using components such as coffee, fenugreek, green tea, bringaraj, onion seeds, orange oil, and lemon oil were developed and compared against the marketed standard. The effect of various extracts on the parameters such as surface tension, foam test and foam stability test, viscosity, cleansing test, sag test, dirt dispersion, wetting time and pH was successfully tested. All the formulations were found to be beneficial in eliminating oil, dirt, and dandruff, encouraging smooth, silky hair appearance, fortifying and darkening hair without altering or harming hair tresses. Our findings suggest the incorporation of fenugreek, lemon and orange peels to increase the cleansing ability. However, the inclusion of onion seeds and green tea has been found to be beneficial in the generation and stability of the foam.

Embedded systems have received significant attention during the last decade mainly because of their numerous applications. They can be found in robotics, smart buildings, fabrication equipments as well as medical, automation, industrial, commercial, military applications. As we know COVID-19 is an infectious disease is a newly discovered. You may be infected by breathing in the virus if you are with in close proximity of someone who has COVID-19, or by touching a contaminated surface & then your eyes, nose or mouth. So it is very harmful & most of the Corona patients are hospitalized so, it is dangerous for hospital staff. A proposed system is a work like medicine distributor in the hospital. In today's world, people are suffering from several diseases and due to this the need for medication has increased exponentially. An average person takes 2-3 tablets a days and there is a chance for the person to miss the tablets. In order to avoid such mistakes an automated system for dispensing medicines is required. In this proposed system, we present a prototype robotic system that automatically dispenses medicines to the patients in the hospital. The robot model which carries medicines for patients will deliver them at the respective time. The robot uses line follower method to deliver the pills to the patient's room. In this way the medication errors can be prevented and the need for the patient to remember their medicines is not needed anymore.
