Landfilling has been widely used for solid waste disposal; however, the generation of leachate can pose a major threat to surrounding environment in form soil salinity. Two native plants North America Puccinellia nuttalliana (alkaligrass) and Typha latifolia (cattail) were selected this study investigate bioaccumulation sodium (Na+) chloride (Cl-) under controlled greenhouse conditions. The treatments include irrigation using fertilizer (F), landfill (LL), tap water (control, C). Plants...

Because traditional QC is discontinuous, laboratories use additional strategies to detect systematic error. One strategy, the delta check, best suited large The moving average (MA) monitors mean patient analyte value but cannot equitably error in skewed distributions. Our study combines check and MA develop an of deltas (AoD) strategy that consecutive, intrapatient results.Arrays differences (delta) between paired results collected within 20-28 h each other were generated from historical...

Within- and/or between-instrument variation may falsely indicate patient trends or obscure real trends. We employ a methodology that transforms sequential intra-patient results into estimates of biologic and analytic variation. previously derived realistic (sb) blood gas (BG) hematology analytes. extend this to derive the imprecision two GEM 4000 BG analyzers.A laboratory data repository provided arterial BG, electrolyte metabolite generated by 4000s on ICU patients in 2012-2013. tabulated...

In this study, cattail (Typha latifolia) was used to remove Na+ and Cl− from polluted soil (PS) in a solid waste open dumping site. Hydroponic system also evaluated landfill leachate. The results indicated that the grown PS had higher biomass yield of 44.4 ± 3.29 g compared control (35.3 4.28 g).

The GEM 4000 (Instrumentation Laboratory, Bedford, MA) is a point-of-care analyzer, primarily used in critical care setting to measure blood gases, glucose, electrolytes, and hemoglobin. Previous studies have shown that the instrument demonstrates increased imprecision compared similar analyzers for iCa, gases when external quality control material run. In this study, accuracy was assessed by comparing patient test results corresponding central laboratory patients whose specimens were tested...

Serial differences between intrapatient consecutive measurements can be transformed into Taylor series of variation vs time with the intersection at = 0 (y0) equal to total (analytical + biological preanalytical). With small preanalytical variation, y0, expressed as a percentage mean, is variable component reference change value (RCV) calculation: (CVA2 CVI2)1/2.We determined between-day RCV patient data for 17 analytes and compared them healthy participants' RCVs. We analyzed 653 days...
