The purpose of this study was to evaluate and compare the dental effects of bonded rapid maxillary expansion (RME) and bonded slow maxillary expansion (SME) treatment methods. Subjects with a maxillary bilateral crossbite were selected and two treatment groups each with 12 patients were constructed. At the beginning of treatment, the average chronological ages were 11.96 years for the RME group...

OBJECTIVE Rapid maxillary expansion (RME) is used to expand the maxilla and increase arch perimeter; yet, there are few reports on its effects on the sphenoid bone. With cone-beam computed topography (CBCT), it is possible to visualize sphenoid bone changes. The purpose of this study was to investigate sphenoid bone changes observed in conjunction with RME treatments, using CBCT. METHODS Sixt...

Grey theory was proposed by Prof. Deng [1] for more than 30 years. It has been successfully applied in many academic fields, such as electrical engineering, education, mechanical engineering, agriculture, high-tech sectors and so on [2-8]. Grey theory is famous for easy calculation and satisfactory result. Comparing to other methods, grey theory need only as few as four data could be modeled to...

in order to evaluate the efficiency of empirical competition models for simulation of sugar beet (beta vulgaris l.) yield at interference with redroot pigweed (amaranthus retroflexus l.), a factorial experiment based on randomized complete block design with three replications was carried out. factors were weed densities (d1=1, d2= 4, d3= 8, d4=12 and d5=16 plants m-1 of row) and relative time o...

The prevalence of dental fluorosis in the United States has increased during the last 30 years. In this study, we used a mathematical model commonly employed by the U.S. Environmental Protection Agency to estimate average daily intake of fluoride via all applicable exposure pathways contributing to fluorosis risk for infants and children living in hypothetical fluoridated and nonfluoridated com...

Consumption of edible bird's nest (EBN) has been a common practice for the health benefits it is believed to provide. Hence, this study aimed investigate effects both traditional (TEBN) and convenient bird’s (CEBN) on spatial learning male Sprague Dawley rats in radial arm maze (RAM). A total 24 (270-300 g) were allocated into three groups based diet given namely pellet only (control group), mi...

abstract major of hydrological systems are very complicated and it is not possible to understand them completely, therefore simplification is necessary to understand or control of a part of the system behavior such as water balance relationships. hydrological models are simple structure of complicated systems in water cycle in the nature. the first goal of a hydrological model is function predi...

OBJECTIVE To analyze the responsiveness of the Fibromyalgia Health Assessment Questionnaire (FHAQ) in a group of patients with fibromyalgia (FM). METHODS Observational, prospective and longitudinal study related to the project ICAF was taken part in 15 Spanish centers. 232 patients were included and diagnosed of FM: 98.3% were women, the mean age was 47 years old, they were analyzed at a basa...
