Due to the changes in the composition and processing of acrylic resins, it seems appropriate to evaluate the influence of polymerization methods about the alteration of occlusal vertical dimension and the horizontal positioning of artificial teeth of total dentures. For this, 64 specimens were made, simulating a maxillary total denture waxed from a standard maxillary denture. The experimental s...

Evaluating the maxilla-mandibular vertical dimension is of great importance in constructing successful denture prosthesis, however it is a tedious process which may be misinterpreted leading to false readings. Hence with the aid of cephalometric analysis a cephalogram may present a graphic representation .this study aims to introduce a new mathematical method for of determination the occlusal v...

moment-resisting frames have extensive usage in earthquake-prone areas and high ability in energy dissipation.after the earthquake in northridge 1994,kobe 1995 fixed connections of steel structures have shown poor performance and generally they were caught brittle fracture of beam flange weld to the column.in order to remedy to avoid similar situations in future earthquakes,researchers introduc...

let r be a commutative noetherian ring. we study the behavior of injectiveand at dimension of r-modules under the functors homr(-,-) and -×r-.

Background To assess and compare the effectiveness of two surgical procedures (Beagle's technique and modified Beagle's technique) for the reconstruction of the lost interproximal dental papilla. Materials and Methods Twenty sites were selected based on the selection criteria which included patients within the age group of 20-50 years and the presence of Class I and Class II recession of the ...

In recent years, a number of methods have been developed for the dimension reduction and decomposition of multiple linked high-content data matrices. Typically these methods assume that just one dimension, rows or columns, is shared among the data sources. This shared dimension may represent common features that are measured for different sample sets (i.e., horizontal integration) or a common s...

In this paper, we do research on a new compact storage system which is an extension of conventional automated storage and retrieval system (AS/RS). The new system consists of the S/R machine which travels simultaneously in the horizontal and vertical dimension. At the same time, there is a conveyor system which is in charge of motion of depth dimension which means there are several storage cell...

Innovation by knowledge workers is the foundation of sustainable development within an organization. Chinese policy makers use various innovation incentive policies to improve performance at state-owned enterprises, which in line with China’s goal becoming “innovative country”. This study compares impacts issued central government, local governments, and enterprise level (vertical dimension) ex...

intra-oral appliances such as transpalatal arch and nance appliance fail to resist against forces that tend to loosen the anchorage. the infirmity arises due to the long lever arm and the mesial force that is perpendicular to the long axis of the appliance. the butterfly arch is presented here as an intra-oral appliance that withstands the mesially directed forces with a mechanism that puts str...
