Counter-current acid leaching process for copper azole treated wood waste.

This study explores the performance of a counter-current leaching process (CCLP) for copper extraction from copper azole treated wood waste for recycling of wood and copper. The leaching process uses three acid leaching steps with 0.1 M H2SO4 at 75degrees C and 15% slurry density followed by three rinses with water.

Application of a CCA-treated wood waste decontamination process to other copper-based preservative-treated wood after disposal.

Chromated copper arsenate (CCA)-treated wood was widely used until 2004 for residential and industrial applications. Since 2004, CCA was replaced by alternative copper preservatives such as alkaline copper quaternary (ACQ), copper azole (CA) and micronized copper quaternary (MCQ), for residential applications due to health concerns. Treated wood waste disposal is becoming an issue.

What do we know about partnership with service users and carers in social work education and how robust is the evidence base?

Partnership work with service users and carers in social work education is a policy requirement, and it is also central to the anti-oppressive and rights-based values of social work. This paper reports research findings which are drawn from an educational context, but are also relevant to the wider field of health and social care. The research team undertook a systematic knowledge review using the Evidence for Policy and Practice Information and Coordinating Centre system, which had been used in health and education, but which had not previously been used in social care and social work.

[Intra-familial graft. Respecting public health regulation and professional confidentiality may be incompatible].

Under specific conditions, French law authorizes organ donation despite the donor's seropositivity for certain infectious conditions. The recipient must however be informed of the potential risk of graft-related infection. Anonymous donation being the rule, the rights of the donor are respected since his/her serological status remains a medical secret.

[Patient information: management in the beginning of the XXIth century].

The Conseil d'Etat, the supreme jurisdiction on legislative matters in France, rendered its decree on January 5, 2000, founding its decision on jurisprudence established in 1997 and 1998 by the supreme Court of Appeals. In accordance with this decision, physicians have a legal obligation to inform patients of all possible risks, including very exceptional risks. The information may be given to the patient in any appropriate form.
