Abstract The economic development of rural economies across the global south is often related to access water and infrastructure. It has been argued that construction new dams would unleash agricultural potential African nations are exposed seasonal scarcity, strong interannual rainfall variability, associated uncertainties in availability. While security presented as pathway poverty alleviatio...

In the present study the effect of sewage water and canal water irrigation were compared by their physicochemical properties and heavy metals concentration in soil. The mean values of different physico-chemical parameters and heavy metals were : Bulk density (gm/cm) 1.26, Water holding capacity(%)-53.60, Temperature(oC)-16.33, Electrical conductivity (dsm-1)0.122, pH-7.5, Organic carbon (%)-1.9...

Aim: The objective of this study was to evaluate the effectiveness of manual and ultrasonic instrumentation with varying irrigation protocols on removal of the smear layer from root canal walls. Methods: Forty extracted single rooted human teeth stored in 0.5% saline were used. Periodontal soft tissues were removed followed by crown separation at the CEJ. All the teeth were randomly divided int...

Abstract A determined expansion in the productive capacity of Spanish agriculture was a fundamental and contentious objective during crisis country’s ancien régime formation liberal state, years transition from eighteenth to nineteenth centuries. In this study we examine reorientation that occurred an ambitious project for irrigation region Valencia. region, characterised by well-rooted commerc...

INTRODUCTION The purpose of this study was to determine the effects of citrus aurantifolia (CA) extract on smear layer removal in different parts of root canals. MATERIALS AND METHODS Thirty-nine single-rooted human teeth were randomly divided into three experimental (n=12) and one control (n=3) groups. Teeth were instrumented using MTwo rotary instruments. Root canals were irrigated with NaO...

This work provides a description of the research conducted to assess methods for the discrimination between irrigated and rainfed open-tree canopies using advanced spaceborne thermal emission and reflection radiometer (ASTER) satellite imagery and discrete anisotropic radiative transfer (DART) radiative transfer 3D simulation model. Summer and winter ASTER images were acquired over a study area...

AIM To monitor chlorine consumption from nonagitated aqueous sodium hypochlorite (NaOCl) solutions in human root canals using a recently developed assay, which can determine the order of magnitude of available chlorine in small volumes of liquid. METHODOLOGY The root canals of 80 extracted single-rooted human teeth were instrumented to ProTaper Universal F4 and irrigated using 1% NaOCl. Subse...

INTRODUCTION Effective debridement of the root canal system with chemical irrigants prior to obturation is the key to long-term success of endodontic therapy. The purpose of this study is to compare the antibacterial activity of 2.5% sodium hypochlorite (NaOCl) and 2% iodine potassium iodide (IKI) solutions as intracanal disinfectant in infected root canals during one-visit endodontic treatment...
