Machinery for sowing wheat directly into rice residues has become more common in the rice-wheat systems of the north-west Indo-Gangetic Plains of South Asia, with increasing numbers of farmers now potentially able to access the benefits of residue retention. However, surface residue retention affects soil water and temperature dynamics, thus the optimum sowing date and irrigation management for...
Introduction This in vitro study was designed to evaluate and compare different endodontic irrigation and activation systems for removal of the intracanal smear layer. Methods and Materials Forty recently extracted, non-carious human intact single rooted premolars were selected and divided into five groups (n=10) according to the root canal irrigation systems; syringe and needle irrigation (C...
A decrease in water resources around the globe in irrigated agriculture has resulted in a steep decline in irrigation water availability. Therefore, management options for efficient use of available irrigation water are inevitable. Deciding the critical time, frequency and amount of irrigation are compulsory to achieve higher crop outputs. Hence, this two-year field study was conducted to asses...
Simulating irrigation systems by accounting for various water loss rates is necessary while modeling the hydrology of cultivated canal-irrigated watersheds. The existing approaches to modeling canal irrigation use situation-specific optimization procedures. In addition, they are focused on a water management perspective rather than a hydrologic perspective. In this study, an approach is develop...
BACKGROUND Root canal irrigation carries a risk of extrusion of irrigant into the periapical tissues which can be associated with pain, swelling, and tissue damage. Studies have shown less extrusion with sonic or apical negative pressure devices compared with syringe and side-port needle or passive ultrasonic irrigation with continuous irrigant flow. This study aimed to evaluate the effectivene...
Significant changes in population and cultivation of farmland in Western U.S. over the past 200 years has required the use of extensive irrigation to sustain crop growth in the region. This irrigation has altered the land surface processes in the region and subsequently the local climates by increasing soil moisture levels higher than they naturally would be if no irrigation had taken place. An...
Two distinctive features of Sasanian bridges are their designation as weir-bridges and function in the facilitation irrigation. This has often been used to emphasise a specific administrative centralisation. The author stresses continuity investments infrastructures, from Arsacids Islamic period via Sasanians. It is presented that members elite governing classes well private entrepreneurs provi...
BACKGROUND To evaluate the effects of the amount of irrigation on heat generated during implant site preparation. MATERIAL AND METHODS Ten freshly dissected sheep mandibles were sectioned into 30 equal bone blocks and transferred into a heat-controlled water tank. Implant socket preparations were performed with four consecutive drills. Temperature measurements were performed with a thermocoup...
Anethum graveolens Linn. (Umbelliferae, A. graveolens) is a widely used spice with a long history of traditional medicinal use for the treatment of various ailments. The biosynthesis of secondary metabolites in medicinal and aromatic plants is affected by abiotic stresses such as water deficit. This study was carried out to evaluate seed yield and essential oil of dill under five irrigation dis...
PURPOSE The efficacy of antibiotic therapy for acute sinusitis is controversial. This study aimed to compare the efficacies of amoxicillin with nasal irrigation and nasal irrigation alone for acute sinusitis in children. METHODS This randomized, double-blind, controlled study included 80 children aged 4-15 years with a clinical presentation of acute sinusitis. Patients were randomly assigned ...
