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

RETAIL STORE MANAGEMENT
Retail comes from the French word retailler. It was
used with the meaning of "sale in small quantities" in 1433.
Retail is the last phase of an economic activity. As per
Philip Kotler, Retailing includes all the activities involved
in selling goods or services to the final consumers for
personal or non-business use. It is those business firms in
distribution channel that comes at the end of the pipeline
connecting manufacturers and customers.
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.”
CORPORATE SOCIAL RESPONSIBILITY IN INDIAN BANKING INDUSTRY
Initially Indian commercial banks were classified into four core groups viz. State Bank Group (SBG), Nationalized Banks (NBs), Old Private Sector Banks (OPSBs) and New Private Sector Banks (NPSBs). Then one commercial bank was selected from each of the four core groups. The selection of banks from each group was based on a study conducted by IIM-Udaipur along with Economic Times and an independent organization named Futurescape2. Their study identified India‟s top 100 companies for sustainability and CSR.
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
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
कामकाजी माताएँ एवं किशोर
कुछ शोध परिणामों से यह ज्ञात हुआ है कि व्यवसाय का प्रकार, व्यवसाय की स्थिति/पद तथा माता का व्यवसाय से समझौते का स्तर, माता की क्रियाओं की गुणवत्ता तथा बालकों की देख-रेख के स्तर में महत्वपूर्ण भूमिका का निर्वाह करता है। इस सम्बन्ध में हाॅफमैन (1989) बताते हैं कि व्यवसायरत् माताओं की कि‛ाोर बालिकायें सामाजिक रूप से अपने आपको अधिक समर्थ पाती हैं। उनके आत्मवि‛वास, आत्म उपयुक्ततता एवं स्वतंत्रता की भावना में बढ़ोत्तरी होती है। यही तथ्य बालकों के लिए अलग होता है क्योंकि माताओं का व्यवसायरत् होना कि‛ाोर बालकों पर अलग प्रकार का प्रभाव डालता है। इसके विपरीत बहुत ही सफलतम परिवारों में व्यवसायरत् माताओं के कि‛ाोरों की बुद्धिलब्धि तथा पहचान अधिक उच्च कोटि की होती है। यह विपरीत प्रभाव कई कारणों से प्रभावित होता है।
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.
