 Abstract

Nanostructured material has drawn huge attention due to their attractive photo detection properties. Compare with other materials ZnO has much importance in the device fabrication purpose due to its direct wide band gap of ~ 3.3ev, large excitation binding energy of ~ 60mv at room temperature and high electron mobility. Many works have been reported that use ZnO for the purpose of UV photodetectors. This thesis presents the simulation studies of ZnO based Ultraviolet (UV) Photo-Transistor with and without plasmonic. By using plasmonics the output current increase by a factor of 100, It also improve the source photo current and sensitivity. The simulations were carried out using ATLAS software. The material used in this project is ZnO with a doping concentration of 10^17/cm^3.The plasmonic layer was of platinum nanoparticles. The photodetector was irradiated with intensity of 550 mW/cm^2 UV radiation of wavelength 350nm. The output currents of ZnO based UV Photo Transistors with and without plasmonic layer were found to be 1.2755�10^-5A and 3.048�10^-7A respectively. And the maximum responsivity of the devices was found to be 0.0654mA/W and 0.18????A/W with and without plasmonic layer; respectively it was also observed that there is an appreciable increase (factor of 100) in source photo current in devices with a plasmonic layer.

 Abstract

Learning Disabilities (LD) are problems or difficulties related to the processing of information. A child would find it as a herculean task to understand, articulate his/her thoughts in words, have problems in reasoning, and perform mathematical operations.Another disadvantagethese children have is that since they look �normal� to societal standards, their handicap isn�t considered or handled in the right manner. Instead,they are very often mistaken to be a lazy orstupid or disinterested child. This further discourages children to take any sort of interest in their school work. Such children need to be handled with love and care and lot more patience, rather than being labeled or pushed away as a waste of time to be corrected or taught. An understanding of LD is very important. It is vital for teachers to have the right attitude while dealingwith learning disabled children. The present study aimed at assessing and comparing the attitude of primary school teachers towards learning-disabled children of both government and private schools. The investigator developed a questionnaire to study the demographic characteristics of the respondents and the attitude of teachers with regard to LDin children. The total sample comprised of 400 teachers, of which 200 were from 16 government schools and 200 were from 16 private schools in Urban Bangalore city. Statistical analysis of the acquired data was carried out by applying percentages, mean, standard deviation, chi square and �t� test. The findings of the study revealed that a statistically significant association was found between the level of attitude among the government and private school respondents. The chi-square value being 73.37 was found to be significant at 1% level. It is also seen that the private school respondents had a higher mean score percentage related to attitude (M = 63.60%) when compared to government school respondents (M = 53.10%) on LD in children. However, it was found that both the groups had moderate attitude towards LD in children.

 Abstract

Brain Tumor is an abnormal and uncontrollable growth of brain cells inside the brain. The identification of a brain tumor is a challenge due to the complications in the structure of the brain. We can classify brain tumors in a human brain with the help of these MRI Images collected as Big Data. Classification is the best approach for the identification of images like any kind of medical imaging. Magnetic Resonance Imaging (MRI) which supports to diagnosis the disease easily. Much higher accuracy can be achieved by gaining a better data set with high - resolution images taken directly from the MRI scanner. Moreover, classification techniques can be used to raise the accuracy even higher and reach a level that will allow this tool to be a significant asset to any medical facility dealing with brain tumors. Classification is used for classifying data into different classes according to some constraints. Several major kinds of Classification Algorithms including Artificial Neural Network (ANN) and Support Vector Machine (SVM) are used for classification. On the comparative study towards the while, paper provides a comprehensive inspection of Changed Classification Algorithms and their topographies.

 Abstract

Then God formed man out of the dust of the ground and breathed into his nostrils the breath of life, and man became a living being.Man has made tremendous progress in almost every walk of life. Objects once considered impossible to be achieved have now been achieved by us. What we have achieved and accomplished today could not have been imagined in their dreams by our past generations. Modern scientists and researchers have absolutely changed our life style. Science has been incessantly pouring on us new materials and devices to make our life more happy and comfortable. However, pollution of environment has contaminated our body and mind. We witness despair and disappointment on the faces of our young generation. Signs of restlessness are apparently visible in the dry and dull eyes of our young men and women. Sloping shoulders, flat chests and bulging stomaches have become their characteristics. This research Paper dealt with Pranayam a part of Yoga education as depicted by Maharshi Patanjali as four padas or parts samadhiPada,Sadhanapada,Vibhutipada,Kaivalyapada. How did pranayam effect up on the holistic which related to spiritual realm of a mankind and its development experimented in this research.

 Abstract

A summarization of the different points of the various chapters of the entire thesis has been incorporated in this chapter. A summary, being the essence of the total work , contains the gist but lacks the details of logic and presentation. In the present summary, the chapter serials precede the point serials, so, the fourth point of the third chapter is denoted as 3.4 and so on. It is desirable to refer to the main body of the thesis whenever the summarized statements do not seem to convey the total meaning.

 Abstract

Since long time there is lot of progress in anti-HIV-1 therapy, still antiviral chemotherapy suffers from various side effects and drug resistance. The oxadiazole compound has proved to inhibit integration activity to block viral replication at non-toxic concentrations. To understand the properties, a linear quantitative structure activity relationship (QSAR) model is presented for modeling and predicting the inhibition of HIV-1 integrase. The model was produced by using the stepwise multiple linear regression technique on a database that consist of 67 recently discovered 1, 3, 4-oxadiazole substituted naphthyridine derivatives. The developed QSAR model was evaluated for statistical significance and predictive power; Physicochemical Parameters of all compounds have been calculated using chemsketch program of ACD labs. Further topological indices were calculated using dragon software and connectivity indices along with correlation matrix was used to find out the relationship among compound. The compounds are divided into training set of 55 compounds which includes 82% of whole data set and test set of 12 compounds which include 18% of whole data set. Then the models are made by using observed and estimated values and by plotting graph between them. Thus, the key conclusion of this study is its connectivity index order 1, lowest unoccupied molecular orbitals and further it has significant affect on the inhibition of HIV-1 integrase activity by 1, 3, 4-oxadiazole substituted naphthyridine derivatives. The study will be helpful in designing potent antagonists of HIV-1 integrase.We have observed that in our case R2 for models with biparameteric, tetraparametric molecular descriptors are 0.7368 and 0.7560 respectively while as Veerasamy Ravichandran et al reported 0.643 and 0.748. That's why our results are much more superior then the result reported by Veerasamy Ravichandran et al.

 Abstract

�Oh little one, you are always playing. You are ever happy. You are indifferent to the joys and sorrows of the world. You are my guru.� Said Abadhoota in Srimad Bhagabat, looking at a child playing. (Sahu, 2002) The one who descends on earth as the messenger of the past and ambassador of the future-containing within him/ herself all powers and possibilities is the child. Each child is unique. Each can express his/her unique potentialities if provided with adequate nurture, appropriate environment and the opportunity. Each one can flourish, shine in his / her own line. The world smiles when the child smiles. The child is not only a potential asset of family and nation but also the future of the world. It is the imperative need of citizens of the world to nourish and educate children leading to their total development and self- expression.Sound health can earn all success and happiness in life. A diseased life is disgusting and most painful which hampers all achievement. A diseased body produces a diseased/ depressed mind and weak thoughts. The rapid industrialisation by modern science and technology has created a situation which prevents man for care and attention on his/her personal health. Good health is nature�s gift to man, but man by being occupied with the mechanical life style, has developed a tendency of drifting away from nature. And there is only one way to get out of this vicious circle of mechanical life style is �Pranayam�. It is a science and art of better living. Every child in the world should be taught to Practise Pranayam. It enables their body and mind to function smoothly and efficiently and grow in accordance with the laws of nature. Pranayam has a lot of benefits on human life, Pranayam can provide to the human beings an easy solution for agitation, worries, anger, disappointment, fear and lust & other mental problems. More than that it increases the mental capacity, memory power, sharpness, understanding, foresight investigating power, grasping, wisdom intelligence, and other mental qualities. The child can lead a happy and disease-free life with the knowledge and regular Practice of Pranayam. Regular Practice of Pranayam creates the habit of deep breathing automatically. The most apparent benefits of Pranayam are increased oxygenation of blood and increased blood circulation.Generally speaking Pranayam is a system of rhythmic breathing, which strengthens their lungs, normalizes their blood circulation, thereby curing all diseases and giving them longevity. Much research has been done with regards to the effect of Yoga and Pranayam on the adults and the old on various aspects of their personality. But the effect of Pranayam on the school children on various aspects of their personality leading to their holistic development is yet to be found out, Hence the study.

 Abstract

Highway maintenance, especially pavement rehabilitation or resurfacing, requires lane closures. This work develops an integrated model to help highway agencies in developing traffic control plans for maintenance activities and efficiently managing traffic around highway work zones. Thus, the objective of this study is to develop methods for optimizing work zone characteristics in order to minimize the combined total costs for highway agencies and users. Work zone models are developed for three cases: (1) a single maintained road with steady traffic inflows, (2) a single maintained road with time-dependent inflows and, (3) a road network with multiple detour paths, as well as plans for maintenance activities and managing traffic around highway work zones.

One of the famous Indian writers, Namita Gokhale has sieved different emotions and presented this beautiful concoction of feelings of women from the perspective of a woman. The protagonist, an acid attack survivor, who has the lost the love of her life, feels the pain intimidating and as a solace, she finds her childhood home in the hills soothing to the core. Either one has to bear the pain and live through without a sigh, or find a replacement to fill in the void, and transfer oneself into different realm. The novelist, in this book, has given the answer to the question of survival, which is full of illusions distanced thoroughly from reality. This particular paper is an analysis of those painful events, which have rendered nothing but an agonising life to a woman.
