We present an asymptotic analysis (with the scaled mean free path as small parameter) of the spherical-harmonics expansion (SHE-) model for semiconductors in the case of a large electric eld. The Hilbert and Chapman-Enskog expansions are performed and the dependence of macro-scopic parameter-functions such as the mobility and the diiusivity on the details of the considered elastic and inelastic...

Multiscale design for dealing with 2-scale material and product system is implemented by employing the probabilistic analytical target cascading (PATC) and polynomial chaos expansion (PCE) approaches in this paper. PATC allows design autonomy at each scale subsystem by formulating the multiscale design problem as a hierarchical structure. PCE ensures uncertainties to be propagated within and ac...

A simple SAS software program (SAS Institute, Inc., Cary, North Carolina) was developed for fitting an exact formulation of the 2-stage clonal expansion model accommodating piecewise constant exposures and left and right censoring of observations. Data on leukemia mortality and occupational exposure to benzene among rubber hydrochloride production workers in Ohio (1940-1996) were analyzed by us...

Rapid palatal expansion(RPE) with the tooth-born appliance is not sufficient to apply to the patients with periodontal problem or insufficient tooth anchorage, and it leads to tipping of the anchorage teeth and increasing teeth mobility and root resorption. To avoid these disadvantages, we present the case using palatal screws and custommade palatal expander. A 23-year-old patient underwent sur...

The purpose of this study was to evaluate the morphological structure of palatal rugae in Turkish orthodontic subjects with different sagittal skeletal malocclusions. Orthodontic dental casts of 105 patients (Class I [23 females, 12 males]; 35, Class II [18 females, 17 males]; and 35, Class III [14 females, 21 males] 10-22 years old) were analyzed for rugae patterns. Palatal rugae pattern and n...

BACKGROUND The associations between the length and morphological shape-related characteristics of palatal rugae have not been fully explored. OBJECTIVE We aimed to assess the possible association among various geometric configurations of the palatal rugae in an adult population. MATERIALS AND METHODS The maxillary dental casts of 217 non-growing subjects (95 males, 122 females, mean age 25....

Background:Rugae are the anatomical folds that are located on the anterior third of palate behind the incisive papillae. They are also known as "Plica palatine," and the study of these patterns is called palatoscopy. It can be used in various fields such as sex determination, orthodontics and forensic odontology Aim And Objective:The objective of this article is to analyse different palatal rug...

Thirty-nine Klebsiella pneumoniae carbapenemase (KPC)-producing Pseudomonas aeruginosa isolates, all exhibiting high-level resistance to carbapenems and other β-lactam antibiotics, were isolated in Hangzhou, China. Molecular epidemiology analysis indicated the presence of two dominant clones, namely, clones A and B, both of which belong to sequence type 463 (ST463). A genetic environment analys...

This study was designed to obtain and compare the nasalance scores produced by normal Malay children and those with repaired palatal cleft. Data from 103 noncleft children and 27 children with repaired clefts were included. All children were of Malay origin with the Malay language (Kelantan dialect) as their first language. Two short and simple test stimuli were constructed in the Malay languag...

The feasibility and possible effects of palatal soft-tissue expansion in palatal repair were studied. A prospective longitudinal animal experiment was performed in 75 growing cats assigned to 5 groups. In 31 cats, a midline defect was made, and bipediced flaps were raised at the age of 8 weeks (stimulated Langenbeck operation) in order to create palatal scars. At the age of 14 weeks, custom-mad...
