t he development of national Quality Per formance s tandards for d isposable a bsorbent Products for a dult Incontinence
2013Co-Authors: Nancy Muller, Elaine McinnisAbstract:Disposable absorbent Products are widely used in inpatient care settings and in the community to manage adult urinary and fecal incontinence, but few Product standards exist to help guide their Production or optimal use. Increasing costs and reduced revenues have caused a number of states to evaluate absorbent Product use among persons who receive care at home with the assistance of the Medicaid Waiver Program, further increasing concerns about the lack of Product performance standards. To address these issues, the National Association For Continence (NAFC) formed a council of experts and key stakeholders with the objective of establishing national, independent quality performance standards for disposable absorbent Products provided by states to Waiver Program recipients. The Council consisted of representa- tives from five purposefully selected states, technical directors from six Nonwoven Product manufacturers, an officer of the Nonwoven manufactures trade association, a delegate from an academic nursing program and professional societ- ies, a family caregiver, and a patient representative. Following a consensus method and guidelines for use, nine specific recommendations were developed, posted for public comment, and further refined. Final recommendations for Product performance assessment include: rewet rate (a measure of a Product's ability to withstand multiple incontinent episodes between changes), rate of acquisition (a measure of the speed at which urine is drawn away from the skin by a Product, Product retention capacity (a measure of a Product's capacity to hold fluid without rewetting the skin), sizing options, absorbency levels, Product safety, closure technology, breathable zones (a measure of the air permeability across a textile-like fabric at a controlled differential pressure), and elasticity. The Council also set values for and recommended four quantifiable parameters, and the testing methodology associated with each, to help consumers and states evalu - ate absorbent Products (medium adult size): Maximum Rewet Rate: 250 g for standard briefs or underwear and >400 g for premium briefs or underwear; and Breathability of Zones: Minimum of >100 cubic feet per minute. As these recommendations are implemented, research is needed to evaluate the impact on both cost and quality of care for further refinement and modifications, particularly as technology and knowl - edge is advanced.

Development and Use of Moisture-Suction Relationships for Geosynthetic Clay Liners
DigitalCommons@CalPoly, 2014Co-Authors: Risken, Jacob LawAbstract:A laboratory test program was conducted to determine the moisture-suction relationships of geosynthetic clay liners (GCLs). Moisture-suction relationships were determined by combining suction data from pressure plate tests, contact filter paper tests, and relative humidity tests, then fitting water retention curves (WRCs) to the data. WRCs were determined for wetting processes and drying processes in terms of gravimetric moisture content and volumetric moisture content. The effects of GCL type, hydration solution, wet-dry cycles, and temperature on the moisture-suction relationships were analyzed. The three GCLs of the test program consisted of configurations of woven and Nonwoven geotextiles reinforced with needlepunched fibers. A geofilm was adhesively bonded to the Nonwoven side of one of the GCL Products. The hydration solution tests involved hydrating GCLs with deionized water, tap water, 0.1 M CaCl2, or soil water from a landfill cover test plot for a 30-day conditioning period prior to testing. Cyclic wet-dry tests were conducted on the GCL specimens subjected to 20 wet-dry cycles from 50% to 0% gravimetric moisture content prior to testing. Temperature tests were conducted at 2°C, 20°C, and 40°C. GCL type affected moisture-suction relationships. The GCLs with an adhesively-bonded geofilm exhibited lower air-entry suction and higher residual suction than GCLs without a geofilm. The degree of needlepunched fiber pullout during hydration contributed to hysteresis between wetting WRCs and drying WRCs. Hysteresis was high for suction values below air-entry suction and was low for suction values greater than air-entry suction. Cation exchange reduced the water retention capacity for all three GCL types. The saturated gravimetric moisture contents were reduced from approximately 140% to 70% for wetting WRCs and 210% to 90% for drying WRCs for GCLs hydrated in deionized water compared to CaCl2 solution. Hysteresis of the Nonwoven Product decreased from 71%, to 62%, to 28% with respect to deionized water, tap water, and CaCl2 solution. Hysteresis of the woven Product exposed to soil water was 24% and 0%, in terms of saturated gravimetric moisture content and saturated volumetric moisture content, respectively. The swell index, Atterberg Limits, mole fraction of bound sodium, and scanning electron microscopy images that were determined of bentonite from the conditioned GCLs indicated that changes in water retention capacity corresponded with cation exchange. Wet-dry cycles and temperature affected the moisture-suction behavior for GCLs. Wet-dry cycles reduced hysteresis and increased the swelling capacity of GCL specimens. Microscopy images indicated that wet-dry cycles caused weak orientation of the clay particles. Increasing temperature resulted in a small decrease in water retention capacity. Results of the test program provided a means for predicting unsaturated behavior for GCLs

Cyclic shear test of a geosynthetic clay liner for a secondary containment application
Geosynthetics International, 2010Co-Authors: Chris Athanassopoulos, Patrick J. Fox, Jason D. RossAbstract:ABSTRACT: This note presents the results of a cyclic shear test of a secondary containment liner system composed of sand/GCL/sand. The GCL was a needle-punch-reinforced woven/Nonwoven Product with a thin geomembrane laminated to the Nonwoven side. Under a normal stress of 100 kPa, shearing occurred at the sand/geomembrane interface and the GCL sustained no visible damage after 25 cycles of loading with a displacement amplitude of 20 mm and a frequency of 1 Hz. Material property tests performed on pre-cyclic and post-cyclic GCL samples provided additional evidence that the GCL specimen did not sustain damage due to cyclic loading. Analysis of the cyclic loading data indicates hysteretic stress-displacement behavior that is broadly similar to natural soils and displays strength and stiffness degradation as well as reduction in damping ratio with continued cycling.
