Oxidation is a chemical reaction that transfers electrons from a substance to an oxidizing
agent. Oxi- dation reactions can produce free radicals, which start chain reactions that damage
cells.
Unfortunately, our natural defenses are imperfect. They limit the harm caused by oxygen
but do not eliminate it completely. There is some evidence that as the years go by; oxygeninduced damage to body tissues may accumulate.
This damage has been hypothesized to be a major contributor to ageing and to many of
the degenerative diseases of ageing, including cardiovascular disease, cancer, cataracts, the
age-related decline in the immune system and degenerative diseases of the nervous system

Fracture Behavior of Biological Materials and Interfaces
Fracture Behavior of Inhomogeneous Biological Materials and Interfaces
Biological materials like bone, nacre, human tooth layers are inhomogeneous materials made up of soft collagen, and hard, hydroxyapatite (HAP) mineral arranged in such a fashion so that these materials have higher strength and toughness, the measure of crack resisting behavior in materials, at the same time, which is exclusive in nature for different class of materials available for different application areas. The interfaces in these biological materials are designed in such a fashion so that the load transfer between the constituents takes place so smoothly, therefore, become a region of strength, not susceptible to failure like in other man-made materials and composites. It is important to understand these aspects of biological materials so that they can be mimicked to the novel materials to satisfy the growing need of different industries.
This work is focused on studying different layers of human tooth, and its interface for crack initiation and growth, the crack arresting behavior of the interface layer of the outer cover of human tooth, the enamel, and the inner, dentine, called dentine enamel junction. These works are done by developing a numerical model using the commercial finite element analysis tool, ABAQUS. The crack growth pattern of the enamel and the dentine has also been investigated. The role of porosity and permeability on the energy release rate which is the measure of fracture toughness has also been investigated. The key features of the book are:
- Study on the role of shear modulus of the defect and the matrix material in which the defect is embedded on the energy release rate.
- The role of small coating layer between the outer matrix and the inner layer on the fracture behavior, especially the stress concentrations in these different layers due to change in the elastic modulus.
- The crack growth pattern in human enamel, the outer tooth layer.
- The crack arresting phenomena of the interfacial, dentine enamel junction (DEJ).
- The role of porosity and permeability on the energy release rate in the inner layer of human tooth, dentine.
DENTAL IMPLANT IMAGING
Computed tomography (CT) has been the gold
standard for many years as the information provided is
three-dimensional and generally very accurate. However,
CT examinations are expensive and deliver a relatively
high radiation dose to the patient. The latest imaging
modality introduced is cone beam volumetric tomography
(CBVT) and this technology is very promising with regard
to pre-implant imaging.
BIO MATERIALS FOR DENTAL IMPLANTS
Many surgical procedures have been developed to restore more favorable anatomy for prosthesis support. They include vestibuloplasty, Vestibuloplasty with skin or mucosal grafting; and augmentation with bone grafting procedures. These procedures offered short-term improvement to denture stability and retention; however none showed long-term clinical success. Hence implant dentistry had evolved into a reasonably predictable treatment modality for the majority of such patients
Changing Scenario of Business and Management
The Govt. of India introduced economically favorable policy for housing in June 2015with a vision to provide shelter for all. There are several projects that were scheduled but could not take off due to the pandemic and the remaining existing ones were halted due to various reasons. Thus, PMAY also faced the brunt of pandemic and this chapter aims at highlighting those limitations and providing future roadmap for PMAY.
Why & how NETWORK MARKETING
Network marketing is the fastest growing business in this 21st century in U.S number of people involved in the N.M grew from 18 million to 20 million in 2015. And 11% increase from the previous year. While network marketing continue to attract predominantly women. The business model represents every generation and is generally reflective of America’s diverse population
Unconditional Love Mom
My world is just a small place with all the comforts- Mother’s lap.” This anthology is written in all genres and languages which makes it more beautiful just like our dear mother. A relationship of a mother and a child is “unconditional” because she loves with our flaws, our mistakes, our grievances, continually forgiving us, giving us another chance to improve and a lot more. Unconditional means loving them without any conditions, regardless of the circumstances, accepting them as they are. A mother can only do such wonders. Every page is fascinating and utterly addictive. Mothers will always bring our teeths shine brighter and make us laugh louder because from where we all came into existence is the only place where the unconditional love started. After all God’s perfection on earth lies in our mothers. Thankyou Mom for everything. Hope you thanked your mom too after reading this book.”
ANALOG ELECTRONICS
A better device is the triac, bidirectional thyristor, which allows the full a.c. power to be controlled. It comprises two thyristors connected in parallel and working in opposition but controlled by the same gate. The trigger pulses to a triac are provided by a special device called diac, bidirectional breakdown diode. It is, in effect, two Zener diodes connected back to back. The diac conducts in either direction if the applied voltage reaches the breakdown voltage of about 30 V. This
