Synthesis of plutonium trifluoride by hydro-fluorination and novel thermodynamic data for the PuF3-LiF system
PuF3 was synthetized by hydro-fluorination of PuO2 and subsequent reduction of the product by hydrogenation. The obtained PuF3 was analysed by X-Ray Diffraction (XRD) and found phase-pure. High purity was also confirmed by the melting point analysis using Differential Scanning Calorimetry (DSC). PuF3 was then used for thermodynamic assessment of the PuF3-LiF system. Phase equilibrium points and enthalpy of fusion of the eutectic composition were measured by DSC. XRD analyses of selected samples after DSC measurement confirm that after solidification from the liquid, the system returns to a mixture of LiF and PuF3

Psychological intervention in patients with poor compliance
In this article, the authors examine the compliance of periodontal patients from a behavioral psychology perspective. The causes of non-compliance are analyzed along with the main methods of intervention. An experiment was carried out in which various behaviour modification techniques were compared. This study, in particular, examined the effect of periodontist's use of behaviour modification techniques on patient compliance in four treatment maintenance conditions. A functional analysis of compliance and non-compliance behaviour revealed various treatment opportunities. Hence, 4 treatment conditions (which included basic oral hygiene instructions, performance feedback, behavioural self-management, and positive reinforcement) were compared in 3 phases. Data collected over a period of 3 months indicated that behavioural self-management plus positive reinforcement increase patient compliance significantly. Implications for further research are discussed in terms of analyzing the cost of each component procedure for both the patient and the doctor in terms of time, money and effort required. Hence, the present study demonstrates that behavioural strategies can make a significant contribution to the area of patient management
