Introduction: This in vitro study was designed to compare the antimicrobial effects of PIPS® laser activation of irrigant against established 3-week bacterial biofilms to traditional needle irrigation in root canal therapy. Methods: Twenty-four extracted human teeth of one common canal configuration (Vertucci Type II) were endodontically cleaned and shaped using two different preparations (flar...

Plastic film mulching (PM) is widely utilized for maize production in China. However, the effect of PM on the grain yield of crops has not been established, and the biochemical mechanism underlying the increase or decrease in grain yield under PM is not yet understood. Grain filling markedly affects the grain yield. The objective of this study was to investigate the effects of PM on maize grain...

A comparative study about twomodels, Muskingum and integrator-delay (ID) models, for canal control is presented.The former is a simplified hydrological model which is very simple and extensively used in hydraulic engineering for simulation and prediction. The latter is also a model with physical meaning and is widely used for irrigation canals control. Due to a lack of general awareness of Musk...

The use of Precision Agriculture systems is in its infancy in Greece, because of the high fragmented land and the adherence of farmers to traditional farming methods. This paper presents the design, implementation and performance evaluation of an integrated agricultural monitoring and irrigation system using energy-autonomous wireless sensors and actuators. Monitoring and irrigation of the fiel...

[1] Using sugarcane as a case study, this paper shows how an agronomic model can be used to estimate the marginal value of stored irrigation water with uncertain future rain. We do this by estimating production functions that have the water available for use as the variable factor of production (referring to them as allocation production functions). These differ from more ‘‘traditional’’ produc...

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 Periodontitis is inflammation of supporting tooth structure. Most individuals get affected by this disease if oral hygiene is not maintained. There are various mechanical and chemical methods for oral hygiene maintenance. In recent past, interest has been diverted toward the herbal/traditional product in oral hygiene maintenance as they are free from untoward effect. AIM To asses...
