The dentine-pulp complex is normally protected from the microbial invasion by the intact enamel and cementum. The ingress of invading bacteria occurs when there is a break in the integrity of the overlying enamel and dentine by caries, trauma, and contamination of the pulp during dental treatment (including root canal treatment), seepage of saliva through cracks or inadequate coronal restorations. The bacteria of the carious process advances ahead when the infecting pathogen enters through caries. When there is trauma without pulp exposure, the access of the bacteria is through the dentinal tubules. With the establishment of infection, the microbial flora changes from an initially predominant facultative Gram positive flora to a completely anaerobic Gram negative bacteria when the canals have been infected for 3 months or more

A Detailed Survey On Religiosity And Paranormal Experiences
This study is about people in their formative years. It is about their beliefs and practices. It is about their personality and how it relates to their beliefs. It involves empirical investigation of 1800 college going men (882) and women (918) with an average age of about 20 years. The subjects are predominantly Hindu (85%), with 12% Christian and 3% Muslim student attending colleges in Visakhapatnam urban area. Data were collected from them using the Myers-Briggs Type Indicator (MBTI) and the two specially developed questionnaires that survey religiosity and paranormal beliefs and experiences. Paranormal beliefs and experiences surveyed included sacred as well as secular beliefs, experiences, and practices. While several studies in the West attempted to explore the relationships between personality, paranormal beliefs and religious practices and experiences, there are hardly any investigations in non-Judeo-Christian cultures. The present study can help by throwing light on the cross-cultural relevance of these findings

ENTREPRENEURSHIP AMIDST PANDEMIC COVID19
MSMEs play a notable role in economic and social
development, thereby providing flip to entrepreneurship, as they
have inherent features of being innovative and responsive to
changing market changing aspects. MSMEs not only play a crucial
role in providing large employment opportunities at comparatively
lower capital cost but also encourage entrepreneurial activities in
rural and backward areas. But, the large units or Multi-National
Companies are in a better position in the competitive world with
large capital, human resources and Research & Development

ADVANCE DIAGNOSTIC AIDS IN SCREENING OF ORAL CANCER
Oral cancer is the sixth most common malignancy with almost 500000 new cases reported worldwide annually. The diagnosis of oral cancer at an early stage has a good prognosis as the survival rate is high (around 80%). However, the majority of oral cancer cases are diagnosed at a later stage with a considerably poor 5-year survival rate of 50% according to World Health Organization statistics. Thus, an effective management strategy for oral cancer will depend on its early identification and intervention which would pave the way for superior prognosi

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.
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
Mastering Arduino Basics in 30 Days
Connect the components by following the circuit diagram .Remember that potentiometers have three pins. Outer Pins are used for the vcc (Power Source) and the other is ground. The middle pins (output) give us the variable of resistance value.
