AIMS AND OBJECTIVES This randomised controlled trial was conducted to estimate the cost-effectiveness of a nurse-led education and psychosocial support programme for patients with heart failure (HF) and their partners. BACKGROUND There are few studies evaluating cost-effectiveness of interventions among HF patient-partner dyads. METHODS Dyads randomised to the experimental group received nu...

The materials which are applied in modem motor vehicles can be considered to be optimally accommodated to the actual demands. Normally a change of materials is only required if by that a cost reduction can be realized, or if the demands change. Such changes at present or in the near future mainly concern ecological aspects: consumption reduction; weight reduction; low emission of pollutants by ...

In this work, prawn shell was studied as raw material for the production of mesoporous adsorbents via hydrocarbonization, studying the effect of temperature and time on the process reactivity and final characteristics of the hydrochars. By suitable characterization technique analyses (N2 adsorption at 77 K, SEM observation, ultimate analysis, surface composition), the materials were examined. I...

Adsorption is one important technique in fluoride removal from aqueous solutions. The viability of adsorption techniques is greatly dependent on the development of adsorptive materials. A large number of materials have been tested at a fluoride concentration greater than 2 mg/l, and the lowest limit for fluoride reduction by them is about 2 mg/l. Decreasing the fluoride concentration to less th...
