The use of denture adhesives is common among denture wearers, and it is also prescribed by many dentists. Prescribing denture adhesives has been viewed by many prosthodontists as a means of ...compensating for any defects in the fabrication procedures. Denture adhesives add to the retention and thereby improve chewing ability, reduce any instability, provide comfort and eliminate the accumulation of food debris beneath the dentures. Consequently, they increase the patient's sense of security and satisfaction. However, obtaining the advice of the dental practitioner prior to the use of adhesives is a must.
This study was undertaken to compare the retention between sectional border molding using low fusing greenstick compound and single step border molding using condensation silicone (putty) impression ...material in three stages- A. Immediately following border molding, B. After final impression and C. With the finished permanent denture base.
In this study evaluation of retentive values of sectional border molding (Group I) (custom impression trays border molded with green stick compound ) and single step border molding (Group II) ( border molding with condensation silicone (putty) impression material ). In both techniques definitive wash impression were made with light body condensation silicone and permanent denture base with heat cure polymerization resin.
Group II was significantly higher (mean=8011.43) than Group I (mean=5777.43) in test-A. The t-value (1.5883) infers that there was significant difference between Group I and Group II (p =0.15). Group I was significantly higher (mean=6718.57) than Group II (mean=5224.29) in test -B. The t-value (1.6909) infers that there was significant difference between Group I and Group II (p=0.17). Group II was higher (mean=4025.14) than Group I (mean=3835.07) in test -C. The t-value was 0.1239. But it was found to be statistically insignificant (p=0.005).
Within the limitation of this clinical study border molding custom tray with low fusing green stick compound provided similar retention as compared to custom impression tray with condensation silicone in permanent denture base.

Aim:
To compare the effect of four different finishing systems and diamond paste on ceramic roughness with the objectives of evaluating the roughness of ceramic surface of prepared specimens after ...abrasion, finishing and polishing.
Materials & Methods:
A total of 50 test specimens were fabricated in the form of discs of diameter 13mm and 0.6mm thickness. Test specimens were then randomly distributed into five groups of 10 and coded. All the test specimens were then abraded with 125μm diamond in unidirectional motion to create surface roughness that will simulate occlusal or incisal correction. The values were recorded and the specimens were then finished using the various finishing systems. multiple range tests by Duncan's procedure. One way Anova was used to calculate the p-value
Results:
After fini shing, the Ra,Rq,Rz and Rt values showed a tendency to decline to levels much inferior to the values obtained after the preparation of the specimens. Ra values of group III specimens were slightly higher and the increase was significant. The highest Rt value 5.29 obtained after polishing is below the lowest roughness values 7.42 obtained after finishing the specimens.
Conclusions:
Finishing and polishing procedures have a significant role in reducing the roughness of ceramics.Following abrasion with diamond point to simulate clinical adjustment the roughness values doubled when compared to the initial reading.Ra, Rq,Rz and Rt values suggest that Sof lex is the most efficient of all the systems tested followed by auto glazing.After the final diamond paste polishing, sof lex group specimens showed the best finish and auto glazed specimens showed a value almost as equal to the so flex group.

Recently, the importance of targeted covalent inhibitors in addressing potency, selectivity and drug resistance has become of great interest, especially in the area of non-small cell lung cancer ...(NSCLC). Although several covalent EGFR TKIs that are advancing in NSCLC clinical development are active against mutations which are refractory to the reversible TKI drugs Tarceva and Iressa, limited chemical diversity has been explored; all of the irreversible and reversible clinical compounds share the same quinazoline scaffold. We describe the design of a novel pyrimidine-based irreversible inhibitor of EGFR (CNX17) which is active against both the WT EGFR as well as the resistance mutation L858R/T790M in biochemical assays. The inhibitor is also a potent inhibitor of EGFR signaling, including the L858R/T790M resistance mutation in cells (H1975 cell line, EC50 441 nM). Importantly, it also potently inhibits proliferation in both HCC827 (EGFR
Δ746-750
EC50 < 5 nM) and H1975 (EC50 134 nM). This novel chemical scaffold may be an important addition to the armamentarium in overcoming drug resistance to current EGFR therapies.

The Telecom operator companies in order to optimize the capital investments, they share their operations with the infrastructure management companies. There are so many challenges in power system for ...the infrastructure management companies as well as telecom operators. These telecom companies are looking for effective solutions that can reduce their operating cost in managing their power system. The aim of this project is to overcome the challenges facing in the power sector of telecom companies. This project consists of the combination of hardware and software system that gives a "Real Time" data of the telecom sites presents in remote areas and also generate reports that can give an analysis of the energy used by different operators to the concerned companies. A Centralized Management System where all the information of remote equipment monitoring, access, control and security is assured in one common platform. It bridges the vital site to Network Administrator to view the real site status and its criticalities. The System is made mainly with an aspect of security and energy saving. This is done with the help of SCADA (Supervisory Control And Data Acquisition) which monitors and controls the remote sites. The system gives a solution to the critical issues with the help of SCADA. The Remote monitoring system is designed with the purpose of monitoring of telecom sites in remote areas which increases energy saving and reduces manpower. The data received at the server are used to generate highly elaborative and explanatory reports in the form of graphs and comparative data sheet, by which a track on the overall performance of the cell sites can be kept.
With the development of wireless communication technologies, IEEE 802.11 standard has undergone a rapid growth, thanks to low cost and high-speed connectivity. More importantly, the Future wireless ...networks are expected to have the privilege of ubiquitous connectivity extending its support to several applications. Hence effective mechanisms need to be developed to exploit the diversity across a multiple access points and to provide a uniform load distribution in order to improve the QoS of users and to improve the overall composite capacity. In this paper, we propose a cognitive handoff mechanism that adaptively applies full channel scheme before and First Satisfaction First Reservation Handoff (FSFR-HO) Mechanism after minimum delay limitation time of sensitive application used in MH by considering the current active application in use rather than a single fixed threshold value and dynamically changing the threshold value depending upon the currently active applications. In addition to it, we also propose distributive Load Balancing scheme which completely avoids unnecessary overloading of access points by considering the load at the target access point before associating with it.
Techniques for designing fixed parameter algorithms Aravind Prasad, A. G.; Shine, S.
2014 International Conference on Control, Instrumentation, Communication and Computational Technologies (ICCICCT),
2014-July
Conference Proceeding
Fixed parameter approach is one of the theoretically rich and useful design technique to deal with NP-completeness. It analizes running times both in terms of input size and the parameter. The fixed ...parameter O(1) tractable problems can be solved in time f (k)*n O(1) (where n is the size of the given object) for some computable function f. Three design techniques: depth-bounded search trees, kernelization, and iterative compression to develop fixed parameter algorithms are surveyed in this paper. All techniques are described with respect to vertex cover problem.
