'As for dignity and respect…. me bollix': A human rights-based exploration of service user narratives in Irish methadone maintenance treatment.

This paper explores the narratives of service users of contemporary methadone maintenance treatment services (MMT) in the Republic of Ireland to obtain their perspectives in the context of them negotiating their right to health METHODS: Participants were recruited and interviewed by a former service user of MMT services. In-depth qualitative interviews were conducted with 40 current and recent users of MMT services RESULTS: Participants overwhelmingly reported a reduced sense of personal agency because of their experiences in MMT treatment. Participants observed that their perceptions of treatment were forged by a sense of reduced autonomy, coercive and disrespectful approaches from healthcare workers.

New Capabilities in MT3D-USGS for Simulating Unsaturated-Zone Heat Transport.

Changes in climate and land use will alter groundwater heat transport dynamics in the future. These changes will in turn affect watershed processes (e.g.

VS2DRTI: Simulating Heat and Reactive Solute Transport in Variably Saturated Porous Media.

Variably saturated groundwater flow, heat transport, and solute transport are important processes in environmental phenomena, such as the natural evolution of water chemistry of aquifers and streams, the storage of radioactive waste in a geologic repository, the contamination of water resources from acid-rock drainage, and the geologic sequestration of carbon dioxide. Up to now, our ability to simulate these processes simultaneously with fully coupled reactive transport models has been limited to complex and often difficult-to-use models. To address the need for a simple and easy-to-use model, the VS2DRTI software package has been developed for simulating water flow, heat transport, and reactive solute transport through variably saturated porous media.

1DTempPro V2: New Features for Inferring Groundwater/Surface-Water Exchange.

A new version of the computer program 1DTempPro extends the original code to include new capabilities for (1) automated parameter estimation, (2) layer heterogeneity, and (3) time-varying specific discharge. The code serves as an interface to the U.S.

1DTempPro: analyzing temperature profiles for groundwater/surface-water exchange.

A new computer program, 1DTempPro, is presented for the analysis of vertical one-dimensional (1D) temperature profiles under saturated flow conditions. 1DTempPro is a graphical user interface to the U.S.

Modeling variably saturated subsurface solute transport with MODFLOW-UZF and MT3DMS.

The MT3DMS groundwater solute transport model was modified to simulate solute transport in the unsaturated zone by incorporating the unsaturated-zone flow (UZF1) package developed for MODFLOW. The modified MT3DMS code uses a volume-averaged approach in which Lagrangian-based UZF1 fluid fluxes and storage changes are mapped onto a fixed grid. Referred to as UZF-MT3DMS, the linked model was tested against published benchmarks solved analytically as well as against other published codes, most frequently the U.

Effectiveness of two opioid antagonists in treating opioid-induced constipation.

Aim: This literature review reports the effectiveness of two peripheral opioid antagonists to relieve constipation caused by prolonged use of opioids, primarily in patients with advanced cancer.

Background: Opioid-induced constipation can cause great discomfort to patients who use opioids for prolonged periods and on occasion decline pain-relief in an effort to help aid laxation. The use of peripheral opioid antagonists can help reverse the slowing of the gut caused by the opioids, but the correct one must be used in order not to reverse the important analgesic effects the opioids provide.

Variations in pesticide leaching related to land use, pesticide properties, and unsaturated zone thickness.

Pesticide leaching through variably thick soils beneath agricultural fields in Morgan Creek, Maryland was simulated for water years 1995 to 2004 using LEACHM (Leaching Estimation and Chemistry Model). Fifteen individual models were constructed to simulate five depths and three crop rotations with associated pesticide applications. Unsaturated zone thickness averaged 4.

Water movement within the unsaturated zone in four agricultural areas of the United States.

Millions of tons of agricultural fertilizer and pesticides are applied annually in the USA. Due to the potential for these chemicals to migrate to groundwater, a study was conducted in 2004 using field data to calculate water budgets, rates of groundwater recharge and times of water travel through the unsaturated zone and to identify factors that influence these phenomena. Precipitation was the only water input at sites in Indiana and Maryland; irrigation accounted for about 80% of total water input at sites in California and Washington.

Flow and storage in groundwater systems.

The dynamic nature of groundwater is not readily apparent, except where discharge is focused at springs or where recharge enters sinkholes. Yet groundwater flow and storage are continually changing in response to human and climatic stresses. Wise development of groundwater resources requires a more complete understanding of these changes in flow and storage and of their effects on the terrestrial environment and on numerous surface-water features and their biota.
