The prediction of the distribution of quantitative variables in a forest stand is of great interest to forest managers, for the evaluation of forest resources and scheduling of future silvicultural treatments. The aim of this research was to model the distribution of quantitative variables for Quercus persica in open forests in Iran. To investigate the probability distribution of trees in natural stands, 642 trees were selected for measurement using a systematic random sampling method. Selected trees were measured and data were analyzed. Gamma, beta, normal,lognormal, exponential and Weibull probability distributions were fitted to the height distribution of trees. Variables of distribution functions were estimated using the maximum likelihood estimation method. Actual probability and probability which derived from functions was compared using Kolmogorov–Smirnov and Anderson–Darling tests. Beta, Weibull and Weibull probability distributions explained the distributions of tree height, DBH and crown area.

·AIM:To report the characteristics and clinical presentations of retinoblastoma in a series of pediatric patients from Iran. ·METHODS:In this retrospective study, profiles of pediatric patients with retinoblastoma archived in a referral eye hospital in north-west of Iran during 7 years (n =40 patients with 57 eyes) were reviewed. Demographics, as well as the laterality, clinical manifestations and the types of treatment were the major endpoints. The Student’s t test, Mann-Whitney U -test, Chi-square or Fishers’ Exact test was used for analysis where appropriate. ·RESULTS:There were 23 cases (57.7%) with unilateral and 17 cases (42.5%) with bilateral involvement. The male to female ratio was 1 to 1.4 with a mean admitting age of 24.0±11.3 (range:5-62) months. The mean diagnosis delay was (7.4±9.6) months (range:10 days to 13 months). The most common presenting sign was leukocoria (97.5%) followed by proptosis (7.5%), strabismus (7.5%), hyphema (5%), orbital cellulitis (5%) and glaucoma (2.5%). Enucleation was performed in 95.7% of the cases with unilateral involvement and at least one eye of the patients with bilateral disease. A second enucleation was performed in other 3 patients (17.6%) of the latter group. ·CONCLUSION:This is the first study evaluating a series of Iranian children with retinoblastoma.

Sixteen Afshari male lambs (mean live weight 35 ± 1.21 kg, 10 month of age) were used to study the effect of different levels of pistachio epicarp silage (0%, 8%, 17% and 25%) on wool characteristics. The fleece weight (FW), staple length on shoulder (STS), flank (STF), back (STB) and rump (STR), true wool fiber (TW), modulated fiber (MF), kemp fiber (KF) percentage, mean wool fiber diameter (MD) and its coefficient variation (CVMD), breaking load (BL), wool tenacity (WT) and extension (E) were measured. These data were analyzed by one-way ANOVA using SAS software package. The total mean of FW, STS, STB, STF STR;TW, MF, KF, MD, CVMD, BL, WT and E of wool were 1622.2 ± 0.2 gr, 6.20 ± 0.26 cm, 6.80 ± 0.20 cm, 6.50 ± 0.20 cm, 6.90 ± 0.20 cm, 63.30 ± 1.6 mu, 8.30 ± 1.6 mu, 28.40% ± 2.5%, 37.0 ± 0.9 mu, 47.02% ± 2.99%, 7.60 ± 0.3 kgf, 3.40 ± 0.2 gf/tex and 31.1% ± 1.7% respectively, although there was significant difference among treatments on FW, MF, KF, MD, BL and WT. The results showed that feeding lambs with 25% pistachio epicarp silage of total dry matter intake affected wool characteristics and its effect was similar with the control group.

The devastating complexity of decision making in severe dynamic competitive environment of the universe, has forced the wise managers to have relevant strategic plans for their firms. In this paper, a new approach by utilizing Mahalanobis-Taguchi System (MTS) and clustering algorithm in formulating the strategy has been proposed. In this approach, first by performing environmental analysis all internal and external factors affecting organization will be listed. Then the long range goals will be identified by top managers. By applying MTS the main set of factors affecting goals will come out. By identifying main factors, the goal-factor matrix will be formed. At this stage, by using clustering algorithm the proper clusters containing goals and factors influencing them will be constructed. Finally, from the created clusters the appropriate strategies would be generated. The advantage of applying this method is its accuracy and ease of applications in the environment with plenty of goals and numerous factors with interactions among them.
