dental implants have provided exceptional rehabilitative options for edentulous and partially edentulous patients. however, as more implants come into play, the more the clinicians come across problems where specific considerations must be taken into account to meet expectations. the toronto bridge is a treatment modality proposed for restoring several teeth lost in patients with increased crow...
در این پایان نامه به طراحی شبکه های حسگر بی سیم در ساختمانهای هوشمند می پردازیم و در جهت مقایسه دو پروتکل معروف wi-fi و zigbee به اندازه گیری پارامترهای load و packet loss در این پروتکل پرداخته و با پیاده سازی طراحی در شبیه ساز پتولمی به انتخاب بهترین پروتکل با توجه به داده های حاصل از شبیه سازی اشاره می کنیم
Background : Normal hearing is essential for development of appropriate academic and psychosocial skills in children. Many causes of hearing loss are preventable and curable. The aim of this study was to investigate the prevalence of types and probable causes of hearing loss in 15-5 years old hearing impaired children in Isfahan. Methods: In a cross-sectional descriptive study conducted dur...
Efficient and one-pot synthesis of 1,8-dioxo-octahydroxanthenes was described by Knoevenagel condensation, Michael addition and cyclodehydration of dimedone. This reaction was carried out through condensation of dimedone and various aromatic aldehydes in the presence of task-specific Brønsted acidic ionic liquid under solvent free conditions. The catalyst could be recycled five times without si...

Root knot nematodes (Meloidogyne spp.) cause yield loss in all countries, of which, M. javanica, is the most widespread species in Iran. In order to identify M. javanica, 100 infected root and soil samples of root knot nematode were collected from different regions of Kerman province. After purification of populations and identification of M. javanica based on morphological and morphometerical ...

conclusions the assr can accurately predict the degree and configuration of hearing loss and discriminate the normal hearing from mild or moderate hearing loss and mild from moderate hearing loss, except for 500 hz. the air-conducted assr could not define the type of hearing loss. results the assr accurately estimates the behavioral thresholds as well as flat and sloping configurations. there w...
