Viscoelastic studies of some phenols from dielectric measurements

Abstract: The variation of dielectric relaxation time with the viscosity of the medium is being exploited in drawing certain quantitative conclusions regarding molecular motion and intermolecular forces in liquids, liquid mixtures, dilute solutions and multi-component polar solutes in dilute solution. With no perfect empirical or theoretical equation in place for the variation of dielectric relaxation time with viscosity, the experimental investigations on different systems only can give an insight. In the present study the results of dielectric measurements carried out on pure samples of o-ethyl phenol, 2-n-butylphenol, 4-n-butylphenol, and 2,6-butylphenol in dilute solutions in different mixed solvents (benzene + paraffin) and on binary mixtures (1 : 1) of p-2-n-butylphenol + 4-n-butylphenol and p-bromonitrobenzene + 2,6-butylphenol, are reported. For comparison, the results on p-bromonitrobenzene + m-bromonitrobenzene as an example of mixture of non-associative liquids was also carried out and the results are pr...

CLEM - A Cloud Based Learning Environment for Millennial: Learn - Anytime, Anywhere

Abstract: We propose a new learning environment for millennial, CLEM. It is the blend of classroom teaching and secured open source web tools to reach all types of learners. CLEM gives the flexibility to the learner to choose his own way of learning. The focus of this experimental finding, (CLEM) is on the knowledge gained by the learner, giving less priority to the mode of learning. Here, classroom presence is made mandatory only for the last class of every week, but is optional for the first three, but all the learners, regardless of the mode of learning chosen, are supposed to reflect their understanding on the instructor's web portal, summarizing the content delivered on that particular day. CLEM comprises of classroom teaching and open source web tools like blogs, discussion forums and group mails/messages to deliver the course content. It aims to enhance the active guided independent learning environment. This paper presents how a better learning effect is achieved using CLEM based on the survey and analysis of students' academic performance. The paper also explores how CLEM could be used as a Web Bulletin Board.

Blood Vessels Extraction of Retinal Image Using Morphological Operations

Abstract: Blood vessel extraction is on high demand now-a-days as it plays very important role is diagnosing eye related disease in faster rate and efficient way as compared to manual segmentation and detection. The proposed algorithm focuses mainly on pre-processing, extraction and removing frills. Pre-processing has the main important role to play as the result is totally dependent on this step, so pre-processing is done by the use of Contrast Limited Adaptive Histogram Equalization (CLAHE). In the next step that is extraction of blood vessels is done through mathematical morphological functions as the vessels resemble patterns. The HRF database consisting of 45 images is used. The proposed algorithm is implemented in MATLAB 2013a software. The proposed method provides the accuracy of 95.95%, 96.26% and 95.37% for healthy, glaucoma and diabetic retinopathy cases respectively.

Excited state electric dipole moments of two exalite dyes from solvatocromic shift measurements

Abstract: The determination of excited state electric dipole moment through solvatochromic shifts of two Exalite dyes, namely, E-392A, E-398 have been carried out using fluorescence shifts and have been found to be less than those calculated through absorption shifts. It is felt that the one calculated using shifts in emission are more reliable. The results are presented and discussed. A qualitative estimate of the orientation of dipole moments in ground and excited state are also presented and discussed.
