Individuals with dementia often experience poor quality of life (QOL) due to behavioral and psychological symptoms (BPSD). Music therapy can reduce BPSD, but most studies have focused on patients mild moderate dementia. We hypothesized that music intervention would beneficial effects compared a no-music control condition, interactive stronger than passive intervention.Thirty-nine individuals severe Alzheimer's disease were randomly blindly assigned two groups (passive or interactive) Control...

Facile H2 heterolysis was found to be mediated by coordinatively unsaturated Cp*Ir and Cp*Rh thiolate complexes. The reaction of iridium complex is reversible, the formation an intermediary Ir-H/thiol detected. reversible conversion between complex+H2 hydride complex+thiol provides intriguing functional model [NiFe] hydrogenase.

The Non-Government Organizations (NGOs) and Non-Profit (NPOs) contributed remarkably to emergency relief activities during the Great East Japan Earthquake. NGOs/NPOs were successful in coordinating with government, private companies, Council of Social Welfare other provide substantial assistance disaster survivors. rise providing was a new phenomenon Japan. This article attempts analyze reason behind such rise.

Abstract Molecular size dependence in third order optical susceptibility χ(3) for evaporated tin-phthalocyanine thin film was examined by methods of a scanning electron microscope technique (SEM) and an harmonic generation (THG) Maker-fringe technique. Evaporated molecular influenced greatly the values χ(3). The thicker grew, greater were. were with increasing orientation OA= A⊥/(A⊥+AII), whose preferential direction parallel to major axis microcrystals.
