In this paper, we classify (n+5)-dimensional nilpotent n-Lie algebras of class two over the arbitrary field, when $n\ge 3$.

Background: Pain is nor always the result of illness or trauma it is also a positive experience in labor and delivery. Pain, due to perineal tear and episiotomy causes distress and anxiety and delays the due emotional tie between mother and the new born. The relief of pain with the aid of non steroid anti- inflammatory sedatives like diclofenac suppositories may result in an improved family health and the mother's ability for self and infant care. Objective: To determine the effects of diclofenac suppository on the intensity of post delivery perineal pain. Design: A clinical trial conducted double blind on a random and control group. First, immediately after perineal repair immediately the intensity of perineal pain was measured with a graduated roller and the first dose of rectal suppository was inserted. The pain was measured by the graduated ruller 12 hours post medication insertion and shown to the subject for identifying the intensity of perineal pain at 24 + 3 48+ 3 and 72+3 hours post delivery a zero score on the answer sheet was evaluated as no pain 1-3 in significant 4-7 moderate and 10 intense pain. Samples: A total of 80 women (first or second delivery) with mediolateral episiotomy or a second degree perineal tear participated in the study the age range was 18-35 years. A non probable continuous group was selected and randomly divided in two groups of 40 each (the study- diclofenac and the control – placebo) Results: The mean pain score 12 hours post delivery in the diclofenac group against the placebo group showed a slight significant difference (p=0.08) the mean pain score 48 hours post partum in the two groups showed a significant different (p=0.03) no significant differences were estimated in the scores 24 and 72 hours post partum in the study and the control group . Conclusion: Diclofenac suppositories showed to be effective in decreasing perineal pain 12 and 48 hours post delivery. Even though statistical tests showed no difference 24 hours post delivery in the two groups yet the medication can well be utilized for post delivery perineal pain relief. Since diclofenac 100 M.G. Suppositories were used only twice in this study prescribing more frequent doses may bring better relief for which further research is recommended.

Objectives: Since problem solving group training is a comprehensive, active program and based-on cognitive behavioral approach, the aim of present study was to determine the effectiveness of problem solving therapy on depression and coping style in patients with type 2 diabetes mellitus. Methods: In an experimental design the study was done with pretest-posttest with control group. Totally 30 female clients who had inclusion criteria with score of 20-28 in Beck Depression Inventory was selected from Prophet Mohammad hospital in Tehran and divided to two groups. Then coping skills questionnaire was completed by experimental and control group. The experimental group participated in seven sessions on problem solving therapy, while the control group received no intervention. T-test analysis and variance analysis with repeated measures on one variable were used for data analysis. Results: The results of variance analysis show that teaching problem solving therapy on Zurilla and Goldfried model lead to significant reducing emotion focused coping skills and significant increasing problem focused coping skills among patients with type 2 diabetes on the experimental group. The results also indicated significant reducing depression between this individual in experimental groups. Discussion: The results of this study indicated that problem solving therapy could be effective way for improvement coping skill and reducing depression in patients with type 2 diabetes mellitus.
