sugarcane, which has high water requirements, is grown in khuzestan province (iran). climate and optimizing the use of water is very important to sustainable cultivation of sugarcane. studies of water requirements for sugar cane in khuzestan show that in parts of sugarcane agro-industry, the water applied is more than the actual water requirement of the plant. the present study was conducted to...
Background The separation of runoff components within a model simulation is of great importance for a successful implementation of management measures. Diatoms could be a promising indicator for tile drainage flow due to their diverse preferences to different aquatic habitats. In this study, we collected diatom samples of 9 sites (4 tile drainage, TD, and 5 river sites, Ri) in a German lowland ...
The influence of Pleistocene climatic cycles on Southern Hemisphere biotas is not yet well understood. Australia's eastern coastal margin provides an ideal setting for examining the relative influence of landscape development, sea level fluctuation, and cyclic climatic aridity on the evolution of freshwater biodiversity. We examined the impact of climatic oscillations and physical biogeographic...
Bi-level drainage system is a type of underground drainage systems, in which adjacent drainage lines are installed at different depths. In the Hydraulics Laboratory, Ferdowsi University of Mashhad, a model was built, that include a cube tank 2 meters in length, width and height of 1 meters was made of galvanized. In this model, two rows 20 cm apart from each other drains were installed. As dr...
conclusions pyeloplasty, with adequate spatulation, hemostasis and a watertight anastomosis, represents the mainstay of successful pyeloplasty and there may be no significant benefit for urethral stenting, especially in non-complicated cases. background anderson-hynes dismembered pyeloplasty is the gold standard therapeutic approach to ureteropelvic junction obstruction (upjo). use of a drainag...
background the incidence of prostatic abscess (pa) has markedly declined with the widespread use of antibiotics and the decreasing incidence of urethral gonococcal infections. objectives to evaluate different treatment methods for prostatic abscess and to describe technical points that will improve the outcome of transurethral (tur) drainage of prostatic abscess. patients and methods we perform...
Drainage rigid piles represent a commonly used antiliquefaction treatment for saturated sand foundations. Small-scale model tests on the liquefaction-resistant characteristics of drainage subjected to blasting were conducted in this study. The effect ordinary and disposal foundations was investigated by using carbon dioxide (CO2) fracturing generate explosive vibratory loads. test results showe...
This study assesses the incorporation of nanocellulose in a paperboard feedstock emulating two scenarios industrial processes. It included production 170 g/m2 paperboard, using mixtures short-fiber and long-fiber fractions from recycled pulps with typical mill additives. In all cases, 3 wt. % was added to pulp suspensions. The first scenario involved three types addition mixture 78 long-fiber/2...
In order to produce the world’s growing population food demands, it would be necessary to increase the productivity. Most of this increase should be gain by funding for improving irrigation and drainage at current fields. High costs of these projects and the funds’ limitation make challenges to conduct the projects; so in order to have optimized use of the limited funds, it would be necessary t...
AIM The aim is to investigate, in relation to the volume of blood drained, which type drainage to use after thyroidectomy natural drainage or negative drainage. MATERIAL OF STUDY 141 patients who underwent total thyroidectomy for multinodular thyroid disease between 22 November 2012 and 7 November 2013 were included in the present study. For the 141 patients a randomized method was used with ...
