A new solubilityparameter, SP, for hydrofluorocarbons (HFCs) has been developed (SP=1.175 ln(np)+ 0.025H-0.063F-0.028α-0.018β where np depends on the molar volume and the molar refractivity; H and F are the number of hydrogens and fluorines, respectively, in the molecule; and α and β are the respective numbers of H-C-F and H-C-C-F connections). Values of SP have been used to predict if an HFC would
已经开发出用于氢氟碳化合物(HFC)的新溶解度参数SP(SP = 1.175 ln(np)+ 0.025 H -0.063 F -0.028α-0.018β,其中np取决于摩尔体积和摩尔折射率;H和F分别是分子中氢和氟的数目;而α和β分别是HCF和HCCF连接的数目。SP的价值HFC已被用来预测HFC在25°C下对于各种碳氢化合物是否是良好的溶剂。在异构HFC族中,对烃具有最大溶解能力的单个HFC是那些氟与氢的分离度最大的HFC。将希尔德布兰德溶解度参数δ与半经验SP值进行比较。

Many non-Aboriginal mental health practitioners are confronted by the lack of practical information pertaining to interventions with Aboriginal clientele. Subsequently, this may have engendered uncertainty in potential therapists and counsellors due to the lack of reliable, practical and culturally appropriate information. Those non-Aboriginal mental health practitioners working in the field with Aboriginal clients do so with varying degrees of success and build upon their knowledge base through personal experience and anecdotal information. Unfortunately, this information is often not made available to others working in the field through journal publication. This Practice Note examines a model of intervention aimed at developing relationships to enhance therapeutic interventions at the individual, family and systems level. As a way of clarification, the model is described via a case study involving a psychological intervention with a remote Aboriginal community.
