Abstract Much of the nonpoint N and P entering surface waters Midwest is from agriculture. We determined if constructed wetlands could be used to reduce exports agricultural tile drainage systems waters. Three treatment (0.3 0.8 ha in area, 1200 5400 m 3 volume) that intercepted subsurface water were 1994 on Colo soils (fine‐silty, mixed, superactive, mesic Cumulic Endoaquoll) between upland maize ( Zea mays L.) soybean [ Glycine max (L.) Merr.] cropland adjacent Embarras River. Water (tile...
Tile drainage is the major source of nitrate in upper Midwest, and end-of-tile removal techniques such as wood chip bioreactors have been installed that allow current farming practices to continue, with removed through denitrification. There few multiyear studies examining controls on rates. We evaluated performance two during first 3 yr operation examined factors regulated removal. Bioreactor 2 was subject river flooding, not assessed. 1 had average monthly rates 23 44 g N m−3 d−1 Year 1,...
Highlights Denitrifying woodchip bioreactors treat nitrate-N in a variety of applications and geographies. This review focuses on subsurface drainage bed-style designs (including in-ditch). Monitoring reporting recommendations are provided to advance bioreactor science engineering. Abstract. enhance the natural process denitrification practical way nitrate-nitrogen (N) N-laden water matrices. The design construction for treatment U.S. is guided by USDA-NRCS Conservation Practice Standard...
To determine the incidence of a long QT interval as marker for sudden death in patients with anorexia nervosa and to assess effect refeeding. define by linear regression analysis estimation upper limit confidence (95% CI) compare this commonly used Bazett rate correction formula.Prospective case control study.Tertiary referral unit eating disorders.41 consecutive admitted over an 18 month period. 28 age sex matched normal controls.maximum measured on 12 lead electrocardiograms.43.6%...
Histological changes attributable to busulphan were found at necropsy in the lungs of six out 14 cases chronic granulocytic leukaemia. The alveoli contained persistent fibrinous oedema converting fibrous tissue, and also atypical cells. Only one seven controls with leukaemia showed oedema, cells absent. In from rare fatal pulmonary fibrosis due busulphan, histological similar but more severe. It is concluded that commonly causes on occasions it becomes severe or enough cause lungs. name lung...
Farms less than two hectares constitute most farm holdings in Africa.Most of these farms are operated by rural smallholder farmers who dependent on agriculture for their economic livelihoods.However, they constrained lack capital assets that would enable them to increase agricultural productivity, food security and income.Despite challenges, smallholders contribute significantly the economy, play a significant role natural resource conservation.Therefore, represent critical population...
This study aims at understanding the impacts of projected climate change on hydrological processes within Maumee River watershed (16 395 km 2 ) lying in Lake Erie Basin using soil and water assessment tool (SWAT). The model was calibrated validated for a baseline time‐period 1995–2005. Downscaled ensemble temperature precipitation data from three general circulation models (GCMs) then used to assess future flow, sediment, nutrient loading mid‐century (2045–2055) late‐century (2089–2099) time...
To assess whether the increase in malignant melanoma incidence could be due, at least part, to changes histological criteria of malignancy, pathologists Australia, France, Italy, New Zealand, Norway, Sweden, United Kingdom, States and USSR reviewed diagnoses 50 consecutive pigmented naevi (40 junctional compound; 10 intradermal) 20 melanomas made each participating centre around 1930, 1955 1980. Collaborating re-read material, 2,665 cases all, either from original slide (82%) or a recut...
Summary A prospective blind trial was conducted comparing the analgesia and adverse effects produced by caudal extradural blockade (caudal block) with of dorsal nerves penis (penile in 38 boys undergoing elective circumcision. Analgesia assessed senior nurses using a linear analogue scale response to direct questioning over first 7 hours after surgery. The degree duration postoperative similar two groups. However, block group had higher incidence motor (p = < 0.01). One technical failure...
Abstract A low-cost [$30 (U.S. dollars)] consumer grade GPS receiver with a sideways-mounted antenna has been applied to measure tidal water levels at mesotidal coastal site using an interferometric reflectometry approach. The proof-of-concept system was installed approximately 16 m above mean sea level in close proximity conventional bubbler tide gauge that provided validation data. received signal-to-noise ratios (SNR) for the satellites view were recorded several months during two...
Drainage water management (DWM) is the practice of varying drainage intensity a subsurface system to ensure that no more transported from field than necessary for optimizing crop growth and facilitating seedbed preparation other agrotechnical practices. This variation achieved by using stop logs in control structure adjust outlet elevation system. An experiment was set up test hypothesis implementation this will reduce nitrate (NO<sub>3</sub>) loads systems Illinois, United States, without...
Reducing nitrate loads from corn and soybean, tile-drained, agricultural production systems in the Upper Mississippi River basin is a major challenge that has not been met. We evaluated range of possible management practices biophysical social science perspectives could reduce losses tile-drained fields Salt Fork Embarras watersheds east-central Illinois. Long-term water quality monitoring on these showed averaged 30.6 23.0 kg N ha yr (Embarras watersheds, respectively), with maximum...
Nitrate (NO3−) removal in denitrifying bioreactors is influenced by flow, water chemistry, and design, but it not known how these widely varying factors impact the production of nitrous oxide (N2O) or methane (CH4) across sites. Woodchip link hydrosphere atmosphere this respect, so five full-size Illinois, USA, were monitored for NO3−, N2O, CH4 to better document where treatment technology resides along pollution swapping climate smart spectrum. Both surface fluxes dissolved forms N2O...
ABSTRACT: To quantify the effectiveness of best management practice (BMP) implementation on runoff, sediment, and nutrient yields from a watershed, Nomini Creek watershed water quality monitoring project was initiated in 1985, Westmoreland County, Virginia. The changes nonpoint source (NPS) loadings resulting BMPs were evaluated by comparing selected parameters data series obtained before, during, after periods BMP implementation. results indicated that watershed‐averaged curve number, (N P)...
