BACKGROUND AND AIMS Gingival recession (GR), a common problem in periodontium, is associated with various etiologic factors. There is controversy over the role and importance of these factors. The aim of this study was to evaluate the etiologic factors of GR in a group of subjects in Northwest Iran. MATERIALS AND METHODS In this case-control study, patients referring to a university clinic (1...

BACKGROUND Various techniques for lengthening short columellae have been used for bilateral cleft nose repair. However, previous methods have not yielded satisfactory results. We performed a full-thickness skin graft to lengthen short columellae during secondary cleft nose repair in adult patients. METHODS Ten bilateral cleft lip and nose patients underwent secondary cheiloplasty with open rh...

BACKGROUND/AIM This study aimed to generate data for the S1 and S2 alar pedicle and body and the alar orientations for both dysmorphic and normal sacra. MATERIALS AND METHODS The study comprised two groups: Group N consisted of 53 normal sacra and Group D included 10 dysmorphic sacra. Various features such as alar pedicle circumference; anterior, middle, and posterior axis of the sacral ala; ...

Designs of heat exchangers have mostly been disconnected to the performance of thermoelectric generator (TEG) systems. The development work, mostly focused on thermoelectric materials, required a significant amount of engineering parametric analysis. In this work, a micro plate-fin heat exchanger applied to a TEG is investigated and optimized to maximize the output power and the cost performanc...

Finite element simulation of stretch flanging process was carried out in order to investigate the effect of process parameters on maximum thinning (%) in stretch flanging process. Influences of initial flange length, punch die clearance, width of sheet metal blank and blank holding force were investigated on maximum thinning (%). Finite element simulation was done using FEM software package ABA...

Abstract This paper investigates the settlement in a pavement due to soil liquefaction. Four 1-g shaking table tests were performed on saturated sand bed-pavement model understand factors affecting liquefaction-induced settlements and their relation thickness width. All with base acceleration of 320 gal laminar box. The revealed that total reduced increase thickness. same but different width sh...

Grazing incidence specular and diffuse X-ray scattering measurements have been used to study variations in polishing of InP single crystal wafers. Excellent agreement between experimental and simulated data is achieved when graded surface layers typically 3081 in thickness, and of higher density than the bulk material, are included. Figuring was found on all samples examined and the width of th...

BACKGROUND The Abductor hallucis muscle (AbdH) plays an integral role during gait and is often affected in pathological foot conditions. The aim of this study was to evaluate the within and between-session intra-tester reliability using diagnostic ultrasound of the dorso-plantar thickness, medio-lateral width and cross-sectional area, of the AbdH in asymptomatic adults. METHODS The AbdH muscl...
