Congenital Hairy Polyp of Posterior Tonsillar Pillar

Congenital hairy polyps are exceedingly rare congenital anomalies. We report a case of congenital hairy polyp arising from posterior tonsillar pillar which was excised with bipolar cautry.

بررسی مقایسه ای واکنش زیر جلدی RC Prep ساخت ایران با RC Prep نوع Premier بر روی Albinus Rat

زمینه و هدف: با توجه به کاربرد ماده RC- PREP در آماده سازی کانال دندان و ساخت آن در داخل و هم چنین عدم وجود مطالعه INVIVO در این زمینه این مطالعه با هدف مقایسه واکنش زیر جلدی RC-PREP ساخت ایران با RC – PREP نوع PREMIER انجام گرفت.مواد و روشها: جهت بررسی واکنش زیر جلدی RC-PREP ایرانی و نوع آمریکایی آن (Premier) از 21 Rat آلبینوی بالغ با میانگین وزنی 200±25 گرم استفاده شد. پس از قرار دادن لوله ‌ه...

Room temperature spin valve effect in NiFe/WS₂/Co junctions.

The two-dimensional (2D) layered electronic materials of transition metal dichalcogenides (TMDCs) have been recently proposed as an emerging canddiate for spintronic applications. Here, we report the exfoliated single layer WS2-intelayer based spin valve effect in NiFe/WS2/Co junction from room temperature to 4.2 K. The ratio of relative magnetoresistance in spin valve effect increases from 0.1...

Understanding Chaos using Discrete-Time Map for Buck Converter

----Research in nonlinear dynamics and complexity has made remarkable progress in recent years. Almost all power electronic circuits exhibit some kind of nonlinear behavior e.g., quasi-periodicity, subharmonic oscillations, bifurcation, chaos. The aim of this paper is to investigate the nonlinear phenomenon and chaotic behavior in a DC-DC buck converter. The derivation of the discrete-time map ...
