Centrifugal pumps are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor.

Today, most countries are struggling with the increased number of patients and increased costs of patient care per patient. This is happened because of an unhealthy lifestyle, habits, including stress which increasingly leads to chronic illness such as heart disease even in younger age. Also, it is difficult for doctors to monitor the particular patient for total working hours. In many critical conditions such as the patient is located far away from the hospital or also in case of an old patient who suffers from heart disease and physical disorders, continuous monitoring of the patient is not possible. Normally it is difficult to keep track of abnormalities in patient itself manually. Body temperature is 37 degree Celsius for a normal human being. Patients are not well with manual treatment which doctors normally used for tracking, so there must be a device which would help patient keep track of their health by themselves.

Car security system can be divided into two main parts: one is the active security systems. The other is the passive security system. Anti-lock braking system (ABS) is an important active security system. It can effectively enhance the driving stability, reduce the braking distance, and to some extent, prevent the accident from happening. The emergency brake of a moving car may cause sudden locking of the wheel.

Wastewater treatment is the process of converting wastewater into bilge water so that it can be discharged into the water bodies so that it can be mixed and gets reused due to the natural filtration process. Wastewater usually contains toxic chemicals, bacteria, and other harmful resins. The treatment unit aims at reducing the contaminants to acceptable levels so that it can be discharged back into environment.

Soil Bioengineering is the use of living plant materials to perform engineering function. This technique can be used to treat eroding banks, excess gravel, and unstable slopes and can provide a finished product that treats the problem as well as providing appropriate riparian vegetation.

Upcoming high-rise building techniques employ various forms of curtain wall consisting large discrete panels attached to a steel or reinforced concrete framework. Gun-applied elastomeric sealant are generally used to fill the gaps and joints, applied in-situ in order to seal the gaps and to accommodate movement.

Lime has been used as binding materials since ages because it offers greater durability and less strength while being compared with cement. Hydrated lime is soft, flexible and has the ability to move without cracks. Natural Admixtures are used to increase the strength of lime at an earlier time and this reduces the emission of carbon dioxide on the environment produced by the cement.
