Introduction: Schizophrenia and bipolar I disorder are very common disorders in hospitalized patients. Considering that family problems are one of the factors in the appearance and persistence of schizophrenia and bipolar I disorder, in this study, we decided to investigate and compare the family functioning between these two groups of patients. Methods: The sample consisted of 50 patients with schizophrenia and 50 patients with bipolar I disorder. The third group was the control group which consisted of 50 normal different professions such as teachers, workers, housekeepers and others. Then the Family Functioning Scale (FAD-I) was used and the final results of the three groups were compared by SPSS V21 software. Results: In the schizophrenia group, 88.9% percent of patients had family functioning scores less than 109.81 which showed that they had severe family dysfunction but in the bipolar I disorder group, 11.1% and all participants in the control group, had scores higher than ***: Family dysfunction was seen in schizophrenic patients rather than in the other two groups.

The strengthening mechanisms of Al-TiAl_(3) nanocomposite, fabricated using cold roll bonding, annealing, and accumulative roll bonding(ARB) on Al sheets sandwiching with pure Ti powder were investigated in the present study. With annealing at 590 ℃ for 2 h, TiAl_(3) intermetallic compound was formed. After subsequent ARB process up to 5 cycles, final composite consists of ultrafine Al grains of less than 500 nm with TiAl_(3) particles larger than 200 nm. The strength and hardness of the final composite are 2.5 and 3.5 times the initial values, with an ultimate tensile strength of 400 MPa, which is dominated by grain-boundary strengthening due to the ultrafine Al grains, and Orowan strengthening due to the small TiAl_(3) particles. For comparison, an alternative fabrication route of cold roll bonding–ARB–annealing was also studied. This study showed that annealing before ARB is a critical factor in producing an ultrafine grain structure containing TiAl_(3) particles.
