The purpose of this prospective, randomized, single-blind study was to compare the in vivo antibacterial efficacy of a hand/rotary technique versus a hand/rotary/ultrasound technique in mesial root canals of necrotic mandibular molars. The hand/rotary group consisted of 16 mesial roots prepared with a hand/rotary technique. The hand/rotary/ultrasound group consisted of 15 mesial roots prepared ...

BACKGROUND The most important and demanding aspect of endodontic therapy is considered to be cleaning and shaping. Irrigation is considered a vital adjunct to instrumentation of the root canal for canal debridement. Until date, there is no single solution that simultaneously removes the smear layer and disinfects the entire root canal system. Thus, this in vitro study was designed to evaluate t...

A proper understanding of factors affecting evaporation and drift losses in sprinkle irrigation is important for developing water conservation strategies. For estimating drift and evaporation losses during the set sprinkler irrigation event, several outdoor single-sprinkler and block irrigation tests have been conducted. Various sprinkler±nozzle±riser height combinations were used and the varia...

Both the economics and the engineering of irrigation design are typically based on the assumption of a single source. The more general economic problem is to determine which sources should be developed and how water should be allocated and delivered to various receptor-farmers. This is a problem in network economics. We begin our exploration with the problem of allocating irrigation water from ...

PURPOSE To compare the protective properties and ease of manipulation during cataract surgery of corneal coating with a gel (eyeDRO; AL.CHI.MI.A. S.R.L, Italy) and corneal irrigation with balanced salt solution (BSS). METHODS We analyzed the data of 51 patients receiving either eyeDRO or BSS during routine cataract surgery performed within a 20-day period in 2016. The selected parameters were...

Embedded System based submersible motor control to prevent it from over load, dry run and single phasing using GSM for Agriculture Irrigation is the work done in this project which can be used to control and monitor the submersible motor used for agriculture irrigation using GSM network. This project provides the development of mobile phone as remote control application for submersible motor pu...

We examined resource limitations on growth and carbon allocation in a fast-growing, clonal plantation of Eucalyptus grandis urophylla in Brazil by characterizing responses to annual rainfall, and response to irrigation and fertililization for 2 years. Productivity measures included gross primary production (GPP), total belowground carbon allocation (TBCA), bole growth, and net ecosystem product...

Abstract In most developing countries non-irrigation status often dominates adoption of traditional and modern irrigation technology. In this paper, we study the effect of production risk on irrigation technology choice among small-scale farmers in Chile, applying sample selection and discrete choice models. We find that more educated farmers, with credit access, receiving extension services, a...

OBJECTIVE Patients with diabetes often present with pedal wounds resistant to standard wound healing modalities and become chronic in nature. These chronic wounds in diabetic patients have a high incidence of complications including infection and amputation. Negative pressure wound therapy has been found to facilitate healing of the stagnant pedal wound. This protocol was designed to determine ...
