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...

This paper presents a systematic study of the relation between the size of irrigation systems and the management of uncertainty. We specifically focus on studying, through a stylized theoretical model, how stochasticity in water availability and taxation interacts with the stochastic behavior of the population within irrigation systems. Our results indicate the existence of two key population t...

This overview of Sasanian stuccoes includes sites divided chronologically – without losing sight the regional premises. The iconographic repertoire found in hitherto had been then catalogued ornamental, plant, figural, animal, and monograms. Noteworthy is paragraph on transmission architectural decorations. Although just a few motifs influenced Byzantine decorative language, several were transm...

OBJECTIVE To evaluate the safety and efficacy of the OtoClear Safe Irrigation System for removing cerumen from the external auditory canal in children. METHODS Eligible subjects were 6 months-17 years of age with cerumen obstructing > or = 50% of the tympanic membrane (TM) from view (by otoscopy). Pneumatic otoscopy, tympanometry, and audiometry were performed followed by cleansing of the aff...

This paper develops the system of optimal allocation of water resources in irrigation district and irrigation decision support which integrates technologies of decision support, information management, information search and so on. It has the multi-function of water production function calculation, crop water requirement calculation, water resources optimal allocation and realtime amending the ...

In past couple of decades, there is immediate growth in field of agricultural technology. Utilization of proper method of irrigation by drip is very reasonable and proficient. A various drip irrigation methods have been proposed, but they have been found to be very luxurious and dense to use. The farmer has to maintain watch on irrigation schedule in the conventional drip irrigation system, whi...

Cost effective solar power can be the answer for all our energy needs. Solar powered smart irrigation systems are the answer to the Indian farmer. This system consists of solar powered water pump along with an automatic water flow control using a moisture sensor. It is the proposed solution for the present energy crisis for the Indian farmers. This system conserves electricity by reducing the u...

Precision irrigation in fuzzy control system based on crop water stress acoustic monitoring was designed in the paper. Moreover, conventional double fuzzy control model was found to carry out two work mode, normal irrigation and precision irrigation, which aims to both ensure normal growth of crops and achieve effective water-saving. Since five input signals affect output in different degree, t...
