The soil sorption coefficient Kd and the soil organic carbon sorption coefficient KOC of pesticides are basic parameters used by environmental scientists and regulatory agencies worldwide in describing the environmental fate and behavior of pesticides. They are a measure of the strength of sorption of pesticides to soils and other geosorbent surfaces at the(More)
It is often presumed that all chemicals in soil are available to microorganisms, plant roots, and soil fauna via dermal exposure. Subsequent bioaccumulation through the food chain may then result in exposure to higher organisms. Using the presumption of total availability, national governments reduce environmental threshold levels of regulated chemicals by(More)
The large-scale commercial cultivation of transgenic crops has undergone a steady increase since their introduction 10 years ago. Most of these crops bear introduced traits that are of agronomic importance, such as herbicide or insect resistance. These traits are likely to impact upon the use of pesticides on these crops, as well as the pesticide market as(More)
A self regulating profession, such as nursing, has to have in place systems which deal with practitioners considered unfit to practise. In addition, students studying to enter the profession may also be subject to systems to address concerns about their professional suitability. While the NMC have left it up to each Higher Education Institution (HEI) to(More)
While cultivation of transgenic crops takes place in seven of the EU member states, this constitutes a relatively limited part of the total acreage planted to these crops worldwide. The only glyphosate-resistant (GR) crop grown commercially until recently has been soybean in Romania. In addition, large-scale experimental European data exist for GR sugar and(More)
During application of agrochemicals spray droplets can drift beyond the intended target to non-target receptors, including water, plants and animals. Factors affecting this spray drift include mode of application, droplet size, which can be modified by the nozzle types, formulation adjuvants, wind direction, wind speed, air stability, relative humidity,(More)
This study sought to describe experiences and perceptions of cardiac rehabilitation among a sample of women from South Asian communities. Data were collected via eight semi-structured interviews with staff and a focus group discussion with nine clients from a community-based, culturally sensitive cardiac rehabilitation service. A number of individual,(More)
One of the fundamental problems facing providers and commissioners of health services is how to maintain the skills and knowledge of the workforce during the initial development and implementation of home care services. This small-scale project sought to ascertain if it was possible to use human patient simulation scenarios to educate community nurses about(More)
Recognition of physical deterioration in patients with mental health problems has been recognized as a significant problem. Areas of particular concern include rapid tranquilization, physical restraint, the consumption of alcohol and illicit drugs have the potential to result in sudden and catastrophic patient deterioration. Simulation sessions, using(More)
Falls among older people represent a major public health issue, which can in part be tackled through an integrated falls service combining both primary and secondary prevention. Many falls can be prevented following comprehensive assessment to identify risk factors and to plan interventions to eliminate them or ameliorate their effect. Community nursing(More)
