Two different propagation procedures including aeroponics and soil systems were compared for the minitubers production in potato. The minitubers were evaluated for several quality characters. The plant materials were from three cultivars, Agria, Marfona and Savalan. The plantlets were grown in aeroponics and soil production systems at a plant density of 100 plants per m-2 and stem length, root ...

The goal of each root canal therapy is cleaning and obturating the entire root canal system. A thorough knowledge of root and root canal morphology and a good anticipation of their possible morphologic variations are essential and will help to reduce endodontic failure caused by incomplete root canal preparation and obturation. In this study, one case of maxillary molar with two palatal roots ...
background: endodontic leakage research focus mainly on the quality of the apical seal of the root canal system and the newly introduced resilon/epiphany system claim to be superior to gutta-percha in respect to obturation procedure. the aim of this study is to evaluate the root canal obturation completed by resilon/epiphany system. materials and methods: a total of 42 teeth were selected and w...
Assessing the root system and its tensile strength is necessary for determine the impact of roots in increasing the soil shear strength. The present study aims to investigate effects of slope and flow of riverbank on root system of riparian POPULOYS trees. In a relatively direct interval, 6 riparian POPULOYS trees were chosen on the slope of Simereh riverbank. To assess the root system, the cir...
مقدمه و هدف: یکی از مهمترین فاکتورهای موفقیت در درمان ریشه، آماده سازی مناسب کانال ریشه و تا حد امکان حفظ ناحیه پری آپیکال، بدون تغییر می باشد. تعیین طول کارکرد صحیح، فاکتوری ضروری برای رسیدن به به این هدف می باشد. رایج ترین تکنیکهای تعیین طول کارکرد، رادیوگرافی معمولی و آپکس لوکیتورهای الکترونیکی می باشند. هدف این مطالعه و c-shape آزمایشگاهی، ارزیابی دقت آپکس لوکیتور در اندازه گیری طول کار...
