Study of Heavy Metal ion adsorption from Synthetic Wastewater with the help of biomass and analysis of Mathematical Model
Abstract: The biofilm matrix is a mixture of secreted polymers, metabolites and nutrients ingested, lysis solution products, and even particle debris. This matrix, which is polyanionic by nature, is essential for the activated carbon of metal cations. In this study, the heavy metal adsorption mechanism in biofilms is modelled in one spatial dimension. The numerical method is a free-boundary value issue for nonlinear parabolic and quadratic partial differential equations. Parabolic equations …

An Insight into Industrial Automation
Abstract: Automation is the process of following a pre-defined sequence of operations with or without human labour, by using specialized equipment and machines that perform and control manufacturing processes. Automation in full sense can only be achieved through the combined use of devices, techniques, and equipment capable of perceiving the manufacturing process, making decisions regarding the changes, needed in the operation, and control.

Investigation on the influence of calcium Fluoride and Barium Fluoride on cutting performance during hard turning with minimal fluid application
Abstract: Recently the concept of minimal fluid application has gained attention in metal cutting industry as it has the ability to resemble pure dry turning and at the same time free from all the problems related to large scale use of cutting fluid as in conventional wet turning. Since a very small quantity of cutting fluid is doing cooling and lubrication in minimal fluid application, there must be some performance enhancers …

Review on Vibration Problems in Turbomachinery
Abstract: Vibration suppression of turbomachinery is an important engineering problem. Vibration caused by mass imbalance is a common problem in rotating the turbomachinery systems. Imbalance occurs if the principal axis of inertia of the rotor is not coincident with its geometric axis. Higher speeds cause much greater centrifugal imbalance forces, and the current trend of rotating equipment toward higher power density clearly leads to higher operational speeds. In this paper, a …

Tai Chi Therapy's Effectiveness on Depression and Quality of Life in Elderly Residents of Old Age Homes in Kanyakumari District, Tamil Nadu, India
Abstract: Growing older is the process of ageing. If we can make sure that we are lengthening life in the middle and not simply at the end, older people will live longer and in better health. The “longevity dividend” might be substantial for the societies that adapt to this shifting demography and invest in healthy ageing (WHO). Due to the socio-demographic changes, older adults at times are forced to transit from …
