Synthesis, IR and Raman Spectroscopic Studies of (Ba,Sr)TiO3 Borosilicate Glasses with Addition of La2O3  [PDF]
Chandkiram Gautam, Avadhesh Kumar Yadav, Vijay Kumar Mishra, Kunwar Vikram
Open Journal of Inorganic Non-metallic Materials (OJINM) , 2012, DOI: 10.4236/ojinm.2012.24005
Abstract: A series of glasses were prepared by rapid melt quench method in the glass system (65-x)[(Ba0.6Sr0.4)TiO3]-30[2SiO2-B2O3]-5[K2O]-x[La2O3] (x = 0, 1, 2, 5 and 10). X-ray diffraction of glass samples were carried to check its amorphousity. Density of glass samples were measured using Archimedes principle. The refractive index of these glass samples lies between 2.39 to 2.80. Optical properties of these glass samples were studied using Infrared (IR) and Raman spectroscopic techniques. IR measurements were done over a continous spectral range 450 - 4000 cm-1 to study their stucture networking systematically while Raman spectra were recorded over a continous spectral range 200 - 2000 cm-1.IR spectra of all glass samples showed number of absorption peaks. These absorption peaks occurs due to asymetric vibrational streching of borate by relaxation of the bond B-O of trigonal BO3. The Raman spectra of all glass samples exhibited different spectral bands and intensity of these bands changes drastically. The network structure of these glass samples is mainly based on BO3 and BO4 units placed in different structural groups.

Multilinear Dyadic Operators And Their Commutators
Ishwari Kunwar
Mathematics , 2015,
Abstract: We introduce multilinear analogues of dyadic paraproduct operators and Haar Multipliers, and study boundedness properties of these operators and their commutators. We also characterize dyadic BMO functions via the boundedness of certain paraproducts and also via the boundedness of the commutators of multilinear Haar Multipliers and paraproduct operators.
Multilinear dyadic operators and their commutators in the weighted setting
Ishwari Kunwar
Mathematics , 2015,
Abstract: In this article, we investigate the boundedness properties of the multilinear dyadic paraproduct operators in the weighted setting. We also obtain weighted estimates for the multilinear Haar multipliers and their commutators with dyadic BMO functions.
Evolution of Spatially Inhomogeneous Eco-Systems: An Unified Model Based Approach
Ambarish Kunwar
Quantitative Biology , 2004, DOI: 10.1142/S0129183104006856
Abstract: Recently we have extended our the "unified" model of evolutionary ecology to incorporate the {\it spatial inhomogeneities} of the eco-system and the {\it migration} of individual organisms from one patch to another within the same eco-system. In this paper an extension of our recent model is investigated so as to describe the {\it migration} and {\it speciation} in a more realistic way.
Single Flap Otoendoscopic Myringoplasty for Large Central Perforation—A Pilot Study  [PDF]
Vikram Kulkarni, Mudit Mittal
International Journal of Otolaryngology and Head & Neck Surgery (IJOHNS) , 2014, DOI: 10.4236/ijohns.2014.34030

Introduction: Otoendoscopic myringoplasty has been successfully used for repair of small to medium sized perforation using various materials. Very few studies have used this method for repair of large central perforation. Goals: To evaluate the transcanal otoendoscopic approach to reconstruct large central perforation by raising single flap. Methods Utilized: Pilot study on forty patients with chronic suppurative otitis media dry stage with large central perforation in medical college hospital and research centre was conducted. A zero degree 4 mm otoendoscope and custom made suction elevator was used for myringoplasty. Results: The perforation of thirty eight patients had healed by the end of two months. Conclusion: Otoendoscopic myringoplasty is effective in managing large central perforation and patients need to be observed for longer period to calculate the successful rate.

Materialism, Fashion Involvement, Fashion Innovativeness and Use Innovativeness: Exploring Direct and Indirect Relationships  [PDF]
Vikas Gautam, Vikram Sharma
Theoretical Economics Letters (TEL) , 2018, DOI: 10.4236/tel.2018.811158
Abstract: The objective of the current study was to examine the direct and indirect impacts of materialism on use innovativeness in case of fashion products among Indian consumers. An empirical study was conducted to test these relationships with 282 respondents comprised of 59 percent males and 41 percent of females. Proposed conceptual study model was tested with the help of higher order structural equation modeling by using IBM AMOS 21.0. We confirmed full mediation of fashion involvement in the relationship between materialism and use innovativeness. Furthermore, our study results found full mediation of fashion innovativeness in the relationship between materialism and use innovativeness. On the other hand, materialism had a direct significant negative impact on use innovativeness in case of fashion products. We strongly recommend to the fashion product marketers to highlight the concept of use innovativeness in the entire marketing mix for better business prospects.
Providing Security in VPN by using Tunneling and Firewall
Sonam Wadhwa,Kunwar Pal
International Journal of Engineering and Advanced Technology , 2013,
Abstract: The use of security increased consistently day by day. Huge amount of network requires large amount of security. For maintain things consistent and proper functioning, people require secure way to share information over the network. To accomplish this goal Virtual Private Network is one of the popular techniques. It constructs logical link by using existing public infrastructure. Internet is one of the public networks and VPN utilize the internet to connect the users. IPSec Protocol is a protocol suite based on VPN to protect the communication. For uninterrupted VPN services, it is necessary to provide some mechanism by the combination of tunneling and firewall. This paper proposes a new kind of configuration for security to the public network.
