aesthetic lines after osteotomies, symmetries of the middle third. It is also used for functional recovery of opening the nasal valve. The evaluation of the results of spreader graft is difficult and subjective. Measuring nasal valve angle is an objectie criteria of functional outcome, the brow tip aesthetic lines referred by Tardy and Sheen are options for aesthetic evaluation. Our common indi...

We introduce the generalized rumor spreading model and investigate some properties of this model on different complex social networks. Despite pervious rumor models that both the spreader-spreader (SS) and the spreader-stifler (SR) interactions have the same rate α, we define α and α for SS and SR interactions, respectively. The effect of variation of α and α on the final density of stiflers is...

OBJECTIVE The aim of this study is to use porous high-density polyethylene grafts (Medpor) in open rhinoplasty and then assess complication rate and aesthetic outcomes. METHODS In a prospective cohort study, we performed open rhinoplasty and employed Medpor as rhinoplasty grafts. Then we compared their complication rate. RESULTS In a total of 64 patients, 84 Medpor grafts--8 dorsal grafts, ...

This paper presents the numerical analysis of a Miniature-Scale Refrigeration System (MSRS) for electronics cooling. The system consists of a simulated electronic chip attached to a microchannel cold plate evaporator, a compressor, a microchannel condenser, and an expansion device. The system uses R-134a as the refrigerant. A copper block heater is designed to simulate the heat generation of an...

Spreader grafts (SGs) have been widely used for both aesthetic and functional reasons to prevent middle vault collapse and treat internal nasal valve insufficiency. Although SG precise fixation can be easily achieved in open rhinoplasty, the difficulties of SG placement in closed rhinoplasties can be discouraging. In the present report, we describe a new custom-made SG (called "rail spreader") ...

UNLABELLED A deviated nose is the result of a set of anatomical abnormalities, and for this reason there are many methods for correcting such defects. Therefore we should not use only one single method in all cases of nasal deformities. AIM In this prospective study we propose a new method using a spreader graft on the convex side of the deviated nose. METHODS We performed rhinoplasty in si...

AIM To compare the apical sealing in mesio-buccal canals of extracted molars obturated with low-temperature thermoplasticized gutta-percha or cold lateral condensation techniques using a .06 or a .02 mm/mm tapered gutta-percha master cone. The secondary aim was to evaluate the depth of spreader penetration in root canals using a .06 or a .02 mm/mm tapered gutta-percha master cone. METHODOLOGY...
