Changes in surface land use may threaten groundwater quality and ecosystem integrity, particularly in shallow aquifers where links between groundwater and surface activities are most intimate. In this study we examine the response of groundwater ecosystem to agricultural land uses in the shallow alluvial aquifer of the Gwydir River valley, New South Wales, Australia. We compared groundwater qua...

The effect of irrigation on the abundance of Empoasca vitis (Göthe) populations was investigated in four vineyards located in northeastern Italy. In two experiments, we compared leafhopper population densities in plots irrigated (micro-spray irrigation system) or nonirrigated. In another experiment, we studied the effect of various irrigation systems on E. vitis populations over two successive ...

Bandicota bengalensis, a predominant species inhabiting irrigated fields is a potential pest on agricultural crops and is known to live in extensive burrow systems. The burrow opening covered with mud which is an indicator of its activity seems to be discontinuous. An analysis of burrow systems and their occupations indicated reuse of abandoned burrow systems by new entrants. A study simulated ...

BACKGROUND Ventricular tachycardia recurrence can occur after ventricular tachycardia ablation because of incomplete and nontransmural ventricular lesion formation. We sought to compare the lesions made by a novel irrigated needle catheter to conventional radiofrequency lesions. METHODS AND RESULTS Thirteen female sheep (4.6±0.7 years, 54±8 kg) were studied. In 7 sheep, 60-s radiofrequency ap...

We studied the growth and water balance of young plantations of Pinus radiata D. Don and Eucalyptus grandis W. Hill ex Maiden irrigated with effluent for 3 years in a climate of high net evaporation. The plantations were irrigated weekly with secondary-treated municipal effluent at the estimated water-use rate, or at nominally twice or half this rate. Control plots were irrigated with bore wate...

Article history: Received 17 October 2007 Received in revised form 11 February 2008 Accepted 26 February 2008 Available online 14 April 2008 Humin is an important fraction of soil organic matter that is known to tightly bind many organic compounds. The objective of this study was to evaluate the role of humin as a natural sorbent in soils irrigated with freshwater and treated wastewater. To mee...

Objective. To assess the in vivo hemostatic effect of Ankaferd Blood Stopper (ABS). Study Design. An experimental study of an animal anterior epistaxis model. Setting. A tertiary care university hospital. Subjects and Methods. Wistar rats were randomized into 4 groups of 7 each: group 1, control, no pretreatment, irrigated with saline; group 2, no pretreatment, irrigated with ABS; group 3, cont...

We studied the effect of water availability on basal area growth and wood properties of 11-year-old loblolly pine (Pinus taeda L.) trees from contrasting Florida (FL) (a mix of half-sib families) and South Carolina coastal plain (SC) (a single, half-sib family) genetic material. Increasing soil water availability via irrigation increased average wholecore specific gravity (SG) and latewood perc...

The present study was carried out to assess levels of different heavy metals like Iron, Cadmium, Nickel, Lead, Copper and Zinc in vegetables irrigated with water from different sources industrial area of Naini Allahabad. The order of heavy metal concentration was found in Fe > Zn > Cd > Pb > Ni > Cu in irrigated water and Fe > Ni > Zn > Cu > Cd > Pb was observed in industrial contaminated sites...

AIM To determine if the formation of para-chloroaniline (PCA) can be avoided by using an alternative irrigant following sodium hypochlorite but before chlorhexidine. METHODOLOGY Fifty-five single-rooted teeth were decoronated, instrumented to size 40, .06 taper whilst being irrigated with 14% ethylene-diamine-tetra-acetic acid (EDTA) and 6% NaOCl. Samples were then randomly divided into three...
