मानवाधिकार का आधार मानव के सर्वांगीण विकास के लिए साधन
उपलब्ध कराना है। वस्तुतः मानवाधिकार की नींव ऐसे विचारों से
निर्मित है, जिनके अनुसार सभी व्यक्तियों को प्रकृति ने समान रूप से
समान अधिकार प्रदान किए हैं। मानवाधिकार प्रत्येक व्यक्ति को जन्म
के साथ ही प्राप्त हो जाते हंै, और मृत्युपर्यन्त तक संरक्षित रहते हैं।
मानवाधिकारो ं की प्राप्ति की एकमात्र अर्हता व्यक्ति का मानव होना है
अर्थात् सम्पूर्ण मानवों को यह अधिकार स्वतः ही प्राप्त हो जाते है।
मानवाधिकार गुण-धर्म, प्रतिभा, बुद्धि आदि ऐसे तत्व हैं, जिनसे वंचित
मानव की तुलना पशु से ही की जा सकती है।
STEM CELLS IN DENTISTRY
“And now science has presented us with a hope called stem cell research, which may provide our scientists with many answers that have for so long been beyond our grasp. I don't see how we can turn our backs on this. There are so many diseases that can be cured or at least helped. We've lost so much time already. I can't bear to lose any more.”
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

Sabjiyo ki Adhunik kheti (Hindi)
भारत एक कृषि प्रधान देश है जहाँ की लगभग 70 प्रतिषत जनता कृषि कार्य करती है। बढ़ती हुई जनसंख्या तथा भूमि की उत्पादन दर कम होने के कारण कभी-कभी भोजन की पूर्ति की समस्या गंभीर रूप धारण कर लेती है। भारत में खाद्य पदार्थों का कम उत्पादन होने का दूसरा कारण यह भी है कि यहाँ अधिकतर लोगों की काम करने की क्षमता कम है क्योंकि वे असंतुलित एवं कम पोषण आहार के ऊपर निर्भर रहते हैं अतः स्वास्थय ठीक न रहने से उनकी कार्य करने की क्षमता भी कम होती है। इस प्रकार स्वस्थ्य जीवन के लिए सन्तुलित एवं पोषक आहार जरूरी है।
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
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.
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.
