synthesis and characterization of 6-(hydroxymethyl)-14, 16-dimethyl-13, 14, 16, 17-tetrahydro-6h-13, 17-epiminodibenzo [e, l] [1, 4] dioxacyclotridecin-15 (7h)-oneabstractnew 6-(hydroxymethyl)-14, 16-dimethyl-13, 14, 16, 17-tetrahydro-6h-13, 17-epiminodibenzo [e, l] [1, 4] dioxacyclotridecin-15 (7h)-one (2a) was synthesized in good yield by the petrenko–kritchenko reaction of 2, 2'-((3-hydroxyp...
schiff base sal-2,5-clan = 2-(2,5-dichlorobenzylideneamino)phenol used as a new precursor for preparation of poly-2-(2,5-dichlorobenzylideneamino)phenol (pdcbap). in an aqueous alkaline medium, naocl oxidant is capable of oxidative poly-condensation reaction (op). both sal-2,5-clan and pdcbap were characterized by solubility tests, ft-ir, 1h-nmr spectroscopy and tg-dta studies. ft-ir and 1h-nmr...
background: the final objective of root canal therapy is to create a hermetic seal along the length of the root canal system. for this purpose, many methods and materials have been introduced. the purpose of this study was to compare the apical microleakage in a new obturation technique (true-tug-back) with two other obturation techniques (lateral condensation and chloroform dip technique). met...
Mixed ferroelectrics exhibit unusual precursor effects. In KTa12xNbxO3, polar nanoregions have been shown to condense approximately 20 K above the transition for all Nb concentrations, 1.2%,x,50%, as a result of medium-range collective interactions between Nb off-center ions. These interactions are also responsible for the observation of hysteresis loops in the polarization and dielectric nonli...
The problem of static, non-linear, large three-dimensional deformation of riser bundles used in offshore oil and gas production is studied within the limits of small strain theory. The mathematical model consists of the models of component-risers and connectors which hold risers together. Each riser is modelled as a thin walled, slender, extensible or inextensible tubular beam-column. It is sub...
The majority of the computation of the full component Lagrangian of supergravity coupled to chiral multiplets and a linear multiplet in the U(1)K formulation is presented here. The few remaining quantities to be calculated are isolated for future study. We include an anomalous U(1) factor in the gauge group, and an effective theory of gaugino and hidden sector matter condensation through static...
This paper describes the design and implementation of a radiosonde which can measure the meteorological temperature, humidity, pressure, and other atmospheric data. The system is composed of a CPU, microwave module, temperature sensor, pressure sensor and humidity sensor array. In order to effectively solve the humidity sensor condensation problem due to the low temperatures in the high altitud...
This work develops a framework for recognition of two hand dynamic gestures, using condensation algorithm. The work is broadly divided into three parts. First part of this work deals with skin color identification using color segmentation using' Gaussian Mixture Model'. In the Second part hand motions are modeled as trajectories of some estimated parameters over time. During training, one templ...
Aim: To compare bacterial leakage in root canals obturated with the modified single-cone, lateral condensation, and continuous wave of condensation techniques. Methods: Distobuccal root canals of maxillary molars were shaped up to ProTaper F2 and obturated with modified singlecone, lateral condensation or continuous wave of condensation technique. Two-chamber bacterial model using Enterococcus ...
