Stress, Anxiety and Coping in Adults With Down Syndrome: An Exploratory Co-Research Study.

Background: At least half of children and adults with Down syndrome have a major mental health concern during their life but few studies ask people with Down syndrome directly about their experience. We used a co-research model to explore anxiety, stress, and coping in adults with Down syndrome.

Methods: Our group of researchers and adults with Down syndrome conducted an online survey on mental health for adults with Down syndrome.

Homelessness and Disability in Public-School Students.

Objective: To quantify students with disabilities experiencing homelessness in the Northeastern and Mid-Atlantic US state and district public schools and compare them with those without disabilities.

Methods: Data were compiled from state departments of education and federal homelessness data and were merged by using the Local Education Agency identifier. We calculated the proportion of students with and without disabilities experiencing homelessness and corresponding relative risk 95% confidence intervals.

Quantifying the intersection of disability and homelessness in Massachusetts public schools in 2018-2019.

Background: Homelessness has a major impact on the educational and health trajectories of children. Youth with disabilities may be especially vulnerable to experiencing homelessness, but little epidemiological work has been done to characterize dual disparity. Our goal was to describe the relationship between homelessness and disability among students (age 3-21) receiving public education in Massachusetts in 2018-2019.

Treatment of Legacy Nitrogen as a Compliance Option to Meet Chesapeake Bay TMDL Requirements.

In efforts to combat eutrophication, the U.S. Environmental Protection Agency has established aggressive nitrogen, phosphorus, and sediment reduction goals for states and regulated dischargers within the Chesapeake Bay watershed.

Export of nitrogen and phosphorus from golf courses: A review.

Mitigating the environmental impact of nonpoint source pollution from intensively managed urban and agricultural landscapes is of paramount concern to watershed managers. Golf course turfgrass systems, which receive significant fertilizer inputs, have been cited as significant sources of nutrient loading to groundwater and surface water, but a contemporary synthesis of golf course nutrient export rates is lacking. This review of nitrogen (N) and phosphorus (P) loss from golf courses and the factors affecting it aims to support watershed management efforts and decision making.

Feasibility of Using Woodchip Bioreactors to Treat Legacy Nitrogen to Meet Chesapeake Bay Water Quality Goals.

The United States Environmental Protection Agency has established aggressive nutrient reduction goals to achieve water quality objectives for the Chesapeake Bay estuary. Nitrogen (N) reduction goals are proving particularly difficult to meet with an additional 20.4 million kg of annual nitrogen reductions needed by 2025, and many of the easily achievable and low-cost N reductions have been realized.

Biochar fails to enhance nutrient removal in woodchip bioreactor columns following saturation.

Denitrifying bioreactors are edge-of-field structures that remove excess nitrogen (N) from intercepted agricultural drainage by supporting the activity of denitrifying microorganisms with a saturated organic carbon substrate. Although these bioreactors successfully mitigate N export, the typical woodchip systems have little effect on phosphorus (P), which is also often present in environmentally harmful quantities in drainage waters. Currently, the evidence that amending woodchip bioreactors with biochar enhances both N and P removal rates is mixed, but more work is required to test this hypothesis under controlled conditions.

Performance of an under-loaded denitrifying bioreactor with biochar amendment.

Denitrifying bioreactors are recently-established agricultural best management practices with growing acceptance in the US Midwest but less studied in other agriculturally significant regions, such as the US Mid-Atlantic. A bioreactor was installed in the Virginia Coastal Plain to evaluate performance in this geographically novel region facing challenges managing nutrient pollution. The 25.

Effect of Biochar on Nitrate Removal in a Pilot-Scale Denitrifying Bioreactor.

Denitrifying bioreactors (DNBRs) harness the natural capacity of microorganisms to convert bioavailable nitrogen (N) into inert nitrogen gas (N) by providing a suitable anaerobic habitat and an organic carbon energy source. Woodchip systems are reported to remove 2 to 22 g N m d, but the potential to enhance denitrification with alternative substrates holds promise. The objective of this study was to determine the effect of adding biochar, an organic carbon pyrolysis product, to an in-field, pilot-scale woodchip DNBR.

Enhanced nitrate and phosphate removal in a denitrifying bioreactor with biochar.

Denitrifying bioreactors (DNBRs) are an emerging technology used to remove nitrate-nitrogen (NO) from enriched waters by supporting denitrifying microorganisms with organic carbon in an anaerobic environment. Field-scale investigations have established successful removal of NO from agricultural drainage, but the potential for DNBRs to remediate excess phosphorus (P) exported from agricultural systems has not been addressed. We hypothesized that biochar addition to traditional woodchip DNBRs would enhance NO and P removal and reduce nitrous oxide (NO) emissions based on previous research demonstrating reduced leaching of NO and P and lower greenhouse gas production associated with biochar amendment of agricultural soils.
