factor  is introduced for direct head loss calculation and sizing in dual-diameter laterals of sprinkler and trickle irrigation systems when the hazen-williams equation is to be applied. application of this factor prevents trial and error and uses fewer head-loss equations in calculating the total friction loss and designing dual-diameter laterals. the proposed factor is a function of total num...

OBJECTIVE   The purpose of this study was to assess the presence of the golden proportion (GP) in the facial view tooth-to-tooth width proportion of the six maxillary anterior teeth and to evaluate the width/height (W/H) ratios of the incisors of patients with maxillary lateral incisor (LI) agenesis treated either with implants or orthodontically (by moving canines into the position of the late...

Recent acoustic research has challenged the traditional understanding of the spirantization of Spanish /b d g/. We compare acoustic and EPG results on the realization of /d/ in different contexts. Whereas we largely confirm recent observations regarding the postfricative context, we also show that after nasals and laterals the intensity curve associated with the voiced obstruent /d/ does not of...

in the present study, hydraulic properties of low pressure drip irrigation systems in lateral pipes were evaluated by mathematical model with the aid of experimental data resulting from testing of tubes available in iran. in this regard, emitters discharge were measured in different initial heads from 0.45 to 1.8 m for laterals with outside diameter of 32 mm with different lengths of 89, 60, 30...

This case shows an excellent esthetic treatment outcome using implant-retained crowns replacing maxillary laterals and canines in hypodontia patient with unusual incidence of spontaneous diastema closure after the placement of implants. To our knowledge, this is the first case report showing maxillary midline diastema closure after implant placement.

abstract in order to study the effects of cultivation method and water quantities in drip irrigation on yield of potato, an experiment was carried out using a split plot based on randomized complete block design with 4 replications in torogh agricultural research station (mashhad, iran) for tow years (2001 and 2002). the main-plots were divided into 3 levels of irrigation: i1= 100, i2= 80 and i...
