AIM To evaluate the effect of intracanal cryotherapy with negative pressure irrigation (EndoVac) on postendodontic pain after vital single-visit root canal treatment (RCT). MATERIALS AND METHODS A total of 75 single-rooted teeth with single root canal were treated endodontically. After root canal preparation with Protaper Universal rotary system and irrigation, teeth were divided randomly int...

Recent years have seen continued investments in new irrigation dams across Africa, which led to the emergence of irrigated areas their vicinity (or ‘command areas’). The ability irrigate land that was previously only rainfed allows for an increase crop production and is therefore associated with value generated by agriculture. What produced command major African dams? Here we use water modeling...

Pakistan is home to one of the largest and most complex irrigation infrastructure systems in the world, consisting of 25 million hectares of irrigated agriculture, 56,000 kilometers of main canals, and tubewells in excess of 600,000. Nearly 100 million people depend on 107,000 water courses that are fed by 44 canal systems. Ineffective water management policies in the past have affected water a...

cultivated area, yield and production trend of wheat (triticum aestivum l.), barley (hordeum vulgare l.), potato (solanum tuberosum l.), alfalfa (medicago sativa l.) and chickpea (cicer arietinum l.) as the main crops of kurdistan province were studied during 1983-2006 using time series analysis and the situation of future were predicted for 2006-2021 period. the results showed that the cultiva...

BACKGROUND & OBJECTIVES A new irrigation canal system is under construction in Dhenkanal district of Odisha, to increase the production of rice crop and thereby improve the living standard of farmers in the project area. Construction of canal may increase the transmission of malaria by creating vector breeding habitats. Knowledge about bionomics of vectors will support authorities for appropria...

A large amount of the water diverted for irrigated agriculture seeps from earthen canals during its conveyance to fields. Besides a shortfall in availability, variety environmental and economic damages are caused by canal seepage . Polymer sealants provide an economical alternative permanent liners reducing temporarily. Field studies polymer sealant linear anionic polyacrylamide (LAPAM) conduct...

With growing global concern for food and water insecurity, an efficient method to monitor irrigation projects is essential, especially in the developing world where performance often suboptimal. In Nepal, irrigated area has not been objectively recorded, although their assessment substantial implications national policy, project’s annual budgets, donor funding. Here, we present application of L...

The mean water releases at head section of 11 years Nagarjuna Sagar Jawahar right main Canal, Andhra Pradesh, India is found to be 128.13 TMC (3,627.71 MCM). surface availability was estimated as 2,229 MCM. For the efficient utilization groundwater, quality plays a major role in terms selection crop variety for sustainable agriculture. ground quantity command area available 1385 MCM and annual ...

Besides the risk of filling material extrusion throughout the apex, a satisfactory apical seal can be difficult to achieve in canals with open apices or iatrogenic enlargements of the apical constriction. These situations pose a challenge to root canal filling. This paper describes the root canal filling of a maxillary right canine with an overinstrumented apex, complete loss of the apical stop...
