This paper presents an Improved Discrete Particle Swarm Optimization Technique (IDPSO) in order to determine the optimal number and locations of PMUs for complete observability of a power system for normal operating conditions, as well as for single measurement loss and thereby can be used for power system state estimation. The proposed IDPSO is based on the quantum particle swarm optimization which has a good convergence behavior. To increase the efficiency of the proposed IDPSO the concept of time varying inertia weight and time varying acceleration coefficients are incorporated to the proposed algorithm. The efficiency of the proposed method is verified by the simulation results of IEEE 14–bus, 30– bus, 57–bus–118 bus and Tehran 41–BUS test systems.<\div>

The purpose of the present study was to investigate the effect of Acceptance and Commitment Therapy(ACT) on function of families with children suffering from mental retardation. The method of this studywas quasi–experimental with a pre–test post–test design with a control group. The sample of the studyincluded all the mothers with children suffering from mental retardation in Isfahan. Convenience samplingwas used and 40 individuals were selected and assigned to the experimental and control groups randomly.The participants of the experimental group were exposed to Acceptance and Commitment Therapy(ACT)sessions for 8 sessions of 90 minutes. The control group received no intervention. The instrument of thisstudy included Bloom's Family Functioning Scale. Ancova analysis of covariance was used to analyze thedata. The findings of the study showed that Acceptance and Commitment Therapy(ACT) was effective onfunction of families (P<0.0001).Conclusion: it is better that for increase function of family use of Acceptance and Commitment Therapy–(ACT)<\div>

The present study was carried out to determine the influence of treated barley grain with sodium hydroxide, urea and formaldehyde on degradability of crud protein and dry matter using in situ technique in Gizel sheep. Two fistulated sheep with average BW 45±2.5 kg were used in a complete randomized design. The ruminal dry matter (DM) and crud protein (CP) disappearance was measured at 2, 4, 6, 8, 12, 16, 24, 36 and 48 h. The experimental treatments were A: barley grain treated with 3.5% sodium hydroxide and 1.5% urea, B: barley grain treated with 3.5% sodium hydroxide and 0.4% formaldehyde, C: barley grain treated with 3.5% urea and 0.4% formaldehyde. Parameters of crud protein (CP) for soluble fractions were (a) 41.063, 9.58 and 45.9% and fermentable fractions were (b) 51.16, 85.13 and 51.77% for treatments A, B and C, respectively. According to the survey results, it is clear that grain treated with chemical digestion has high feed potential and if further investigation in ruminant diets can be used as an alternative feed.

Understanding what makes couples strong has given helping professionals specific characteristics they can focus on and develop within families. The aim of this study was to investigate the effects of spiritual well–being, family protective factors, and family strength on marital satisfaction in a propositional structural model. The research population consisted of all the married people of the Isfahan city (Iran), in the year of 2012 with preschool children and in the first decade of marriage with at least 9 grades of education level. Subjects were selected randomly through a multistage sampling from 7 parts of the city (N= 304). The instruments used in this study were the Spiritual Well–being Scale, Inventory of Family Protective Factors, Family Strength Scale, and Revised Dyadic Adjustment Scale. Descriptive statistics and a structural equation modeling analytic approach were used. The analytic model explained 89% of the distribution of marital satisfaction. FS had a strong direct effect on DAS (= 0.89). SWB had indirect standard effects on FS (=0.37) through FPF, and on DAS (= 0.76) through FPF and FS. Also, FPF had indirect standard effect on DAS (= 0.52) through FS (p.000). Consisted to the strength–based approach, the results of this study confirmed the interrelationships among spiritual well–being, family protective factors, and family strength and their simultaneous positive effects on marital satisfaction, and suggest that family counselors employ an integrated spiritual–religious, resilient, and strength–based perspective to inform their work with couples.
