Due to the environmental problems caused by wind erosion, it is necessary to stabilize the dust centers with mulches. The objective of the present study was to determine and compare the optimum vinasse mulches based on mechanical indicators for sensitive soil stabilization to wind erosion. In this research, vinasse (0, 100, 200 g) is combined with bagasse (0, 25, 50 g), ash bagasse (0, 25, 50 g), filtercake (0, 12.5, 25 g), and one-liter water (81 treatments). At first, the treatments were determined in the appropriate range of salinity and acidity (35 treatments) and in the next step, the mechanical indicators have been measured after mulching on laboratory trays (2×30×100 cm). Optimum mulches have been determined based on five indicators by mean comparison (Duncan). The mean comparison showed that treatments 33, 30, 34, 32, and 19 show the mean difference between the groups based on layer thickness, impact resistance, compressive strength, and shear strength properly. It can be concluded that vinasse (100 and 200 g) with 50 g bagasse reduces the crack coefficient greatly, and the application of vinasse, bagasse, and filtercake does not affect the compressive strength and impact resistance.

Nowadays, with the expansion of the internet and its associated technologies, recommender systems have become increasingly common. In this work, the main purpose is to apply new deep learning-based clustering methods to overcome the data sparsity problem and increment the efficiency of recommender systems based on precision, accuracy, F-measure, and recall. Within the suggested model of this research, the hidden biases and input weights values of the extreme learning machine algorithm are produced by the Restricted Boltzmann Machine and then clustering is performed. Also, this study employs the ELM for two approaches, clustering of training data and determine the clusters of test data. The results of the proposed method evaluated in two prediction methods by employing average and Pearson Correlation Coefficient in the MovieLens dataset. Considering the outcomes, it can be clearly said that the suggested method can overcome the problem of data sparsity and achieve higher performance in recommender systems. The results of evaluation of the proposed approach indicate a higher rate of all evaluation metrics while using the average method results in rates of precision, accuracy, recall, and F-Measure come to 80.49, 83.20, 67.84 and 73.62 respectively.

Fatigue and sleep disturbance are side effects of radiation therapy. Grape juice is a traditional product rich in antioxidants and polyphenols that have been shown to include positive effects on improving fatigue and sleep disorders. The aim of this study was to assess effects of grape juice consumption on fatigue and sleep quality in women with breast cancer undergoing radiation therapy.

In this controlled clinical trial, 44 women with breast cancer aged 18–70 years were randomly divided into intervention and control groups. The intervention group consumed 100 g of grape juice daily from the beginning of treatment until five weeks and the control group did not consume any medications or placebo. Fatigue scores and sleep quality were assessed and compared between the two groups at the beginning and end of the study using fatigue questionnaires (MFSI-SF) and sleep quality questionnaires (PSQI). study using fatigue and sleep quality questionnaires(MFSI-SF, PSQI ). Data analysis was carried out using paired t-test and independent t-test.

In this study, physical fatigue scales were significantly different between the two groups with the consumption of grape juice (p < 0.05), but the overall fatigue rates were not significant between the two groups (p ≥ 0.05). By examining the scores linked to sleep quality, it was shown that the sleep disorder scale of the intervention group significantly decreased, compared to the control group (p < 0.05). In the overall quality of sleep or PSQI, significant differences were not observed between the two groups (p ≥  0.05).

Findings of the present study reveal that consumption of grape juice can decrease side effects of radiation therapy (physical fatigue and sleep disorders) in women with breast cancer.

Sleep disruption is a common side effect in breast cancer patients undergoing radiotherapy. Therefore, the aim of this study was to assess effects of tahini consumption on sleep quality in breast cancer patients undergoing radiotherapy.

Forty-eight women with breast cancer undergoing radiotherapy were randomly assigned to intervention and control groups. In the intervention group, daily tahini consumption included 48 g during the radiation therapy course (five weeks). Patients completed Pittsburg sleep quality index questionnaires in the baseline and after the finish of radiotherapy. Chi-square, t-test, Mann-Whitney, Wilcoxon and Binary logistic regression analyses were carried out.

Mean (standard deviation) age of the participants was 47.97 y ±10.65. Moreover, 50% of the patients in tahini group and 80.8% of the patients in control group had poor sleep qualities (p = 0/02). Overall, tahini consumption significantly improved the total score of sleep quality, compared to the control group (p = 0/006). Moreover, significant differences were seen between the two groups in most subscales, including subjective sleep quality (p = 0/008), sleep latency (p = 0/01), sleep duration (p = 0/003) and sleep disturbances (p = 0/05). Moreover, the mean changes in the scale of sleep disturbances showed statistically significant differences between the two groups (p = 0.002). The intervention group had lower odds ratios for the subscales of subjective sleep quality (p = 0.01), sleep latency (p = 0.01), sleep duration (p = 0.006), sleep disturbances (p = 0.04) and total score of sleep quality (p = 0.007), compared to the control group.

These results have shown that tahini consumption during radiotherapy increases the quality of sleep in patients with breast cancer.

 Depressed people are faced with problems in cognitive abilities,emotion regulation and alexithymia.According to previous studies, time perspective as a person's view of his past, present, and personal futurecan help him in improving his cognitive abilities and emotion regulation. The aim of this study was to evaluate the effectiveness of time horizon therapy on cognitive abilities, emotion regulation and alexithymia in depressed teenagers in Yazd.

Statistical population of the quasi-experimental present study include all yazd’s depressed teenaged depressed girl.21 of depressed teenaged girl were purposefully chosen and randolmly were assigned in one interval group (8members) and one control group(13members). The Emotional Regulation Scale (Graz and Roemer, 2004), the Toronto Alexithymia Scale(TAS) (Bagby, Parker, & Taylor, 1994) and the Cognitive Ability Questionnaire (Nejati, 2013) were used to collect research data.
The interval group participated in time perspective program, six 60-minute sessions, twice a week, while the control group was placed on a waiting list. Also, post hoc test was performed to evaluate the stability of the results two months after the training.Statistics data were analyzed using analysis of variance method with repetitive measurement in SPSS_25 software.

Findings showed that Time-perspective therapy has a significant effect on increasing cognitive ability and emotional regulation and reducing alexithymia in depressed female teenaged girls (p <0.05). But effects of intervention just about cognitive ability variable was permanent over the time.(p<0.05).

The results showed that the time perspective program by focusing on factors such as active time managing can have a permanent and ideal effects on cognitive ability.

In order to evaluate the effects of Thymbra spicata and Echinacea purpurea powders on quality of thigh muscle in broiler chickens orally challenged with Campylobacter jejuni, a total of 192 one day old broiler chickens (Ross 308) were randomly assigned to six dietary treatments in a completely randomized design with four replicates of eight birds for 42 days of age. The experimental dietary treatments included: 1) basal diet without additive (control group); 2, 3) basal diet supplemented with Thymbra spicata powder (2.5 and 5 g/kg); 4, 5) basal diet supplemented with Echinacea purpurea powder (2.5 and 5 g/kg) and 6) basal diet supplemented with Erythromycin (0.275 g/kg). All of the chicks were oral-gavaged with Campylobacter jejuni (4×1011 cfu/mL, one mL per bird) on d 21. In the finisher and entire periods, broiler chickens fed Echinacea purpurea (2.5 g/kg), Echinacea purpurea (5 g/kg), and Thymbra spicata (2.5 g/kg) had a higher feed efficiency than those on control diet (P<0.05). Moreover, feeding broiler chickens on diets supplemented with Echinacea purpurea (5 g/kg) and Thymbra spicata (2.5 g/kg) caused a decrease in malondialdehyde concentration of thigh muscle (P<0.05). Furthermore, broiler chickens fed diet containing Thymbra spicata (5 g/kg) had higher press loss (41/2%) and lower crude protein (22.7%) in thigh muscle (P<0.05). According to current results, Echinacea purpurea and Thymbra spicata powders at level of 2.5 g/kg could be recommended because of improving performance and reducing malondialdehyde.

Urinary tract infections are one of the most important bacterial infections, and the most common cause of these infections is E.coli. Considering the importance of E.coli in the development of urinary tract infection in the gastrointestinal tract, the present study was conducted to compare the E.coli causative agent of E.coli infection with E.coli dominating the natural flora of the gastrointestinal tract on the basis of antibiotic resistance and some acute genes. For this descriptive study, 30 women with urinary tract and urinary tract infections were collected from the 30 patients. After colonization and confirmation, three colonies were randomly selected from different parts of each plate (fecal samples and each individual sample) were selected for review. The frequency of hly D and cnf1 genes were determined by PCR method and a phenotypic study of antibiotic resistance of isolates were performed using antibiotic disks. Data were analyzed using descriptive statistics and Chi-square test. Generally 90 isolates of urine and 90 fecal isolates were isolated from the samples. Comparison of the results of urine and fecal isolates showed that the prevalence of examined genes in urine strains was higher than that of fecal isolates (p <0.05). The highest resistance to stool and urinary flora was observed with trimethoprim sulfamethoxazole and gentamicin antibiotics. The highest susceptibility to ciprofloxacin antibiotic (32.2%) was found in urine isolates. In uric acid and fecal Escherichia coli, 37.7% and 46.6% of isolates were resistant to three antibiotics and more. In 9 out of 30 patients, antibiotic resistance and acute genes had the same pattern. Most fecal flora is not an infectious agent, but isolates with higher genetic parameters are effective in causing infection. Considering the greater resistance to trimethoprim sulfamethoxazole and gentamicin antibiotics in both groups, fecal flora may be involved in transferring the gene to antibiotic resistance to urine.

Moringa peregrina (Forssk.) Fiori is an important neglected plant species, with medicinal, industrial and nutritional values, growing in South-East part of Iran. In spite of its high importance in various points of views, the species is not paid enough attention regarding various biologic aspects such as karyotypic characteristics. Four plant populations as well as two tissue cultured samples of the species were used for karyotypic studies. Chromosome dimensions were recorded on which several statistics were estimated for karyotypic asymmetric comparisons on the mentioned plant populations and samples. The recorded karyotypic data were analyzed by nested and factorial statistic models. Chromosomes counting reviled the constant diploid karyotype with 2n=2x=28 chromosomes for all of the studied samples. Analysis of variance showed significant differences (α=1%) between the plant populations and samples based on the recorded karyotypic characteristics. Several anioploid cells were also recorded. It was concluded that the species contains small chromosomes, so that general chromosome means of the studied samples varied between 1.19 to 2.1 μ. The longest genome (51.2μ) belonged to Kenshki sample which was tissue culture based sample. The shortest genome (33.3μ) belonged to Garhoon plant population. In other words tissue culture based samples grouped in distinct classes compared to other studied plant populations. Chanf plant population showed the most symmetric karyotype (45%) based on TF%, whereas, Kenshki plant population revealed the most asymmetric karyotype (41%). DRL statistic and karyotype formula also clarified the mentioned symmetry conditions.

The noble principle of ‘saint-ship’ is one of the main axes of Islamic Sufism and Gnosticism. The need of wayfarer to the help and guidance of a perfect master (shaykh) and saint in the complex mystical journey has constantly been emphasized in educative books of Sufism – whether prose or poem. Hakīm Termāzī is the first Sufi to introduce the concept of saint-ship within the form of a theory and an intellectual system. However, Mohī al-Dīn Ibn Arabī was the one who systematized this theory in a complete and comprehensive manner.The present paper aims at presenting the evolution of saint-ship thought and its related discussions based on the most important prose books of Sufism, and in some cases the poems of prominent Gnostic figures. It covers the theories on saint-ship from third century hejri to the contemporary time that is the beginning of the Constitution. Study of Ibn Arabī and his disciples, related to the al-Andalus school, is due to the importance of Ibn Arabī in the realm of Islamic mysticism and his focus on the perfect human and master.

The mechanisms which are plots for individual's willing to use Morphine are not yet recognized. Carried out researches indicated that tendency to narcotics is increased during stress or after it. In this research we studied the desire change of the second generation to morphine using induced restraint stress which is a kind of behavioral sensitization.

This research was a kind of experimental interferer. At first mice were crossed after insuring about their pregnancy, Sub stress was put on them using special instruments. Some of the embryos head was cut to be studied histologically. After maturing their embryos in order to clarify their left and right handedness to be studied using T-Maze and they were compared with the control group. In order to find the effectiveness of the administrated acute morphine, five groups of stressed and non-stressed were chosen Both groups were divided into five: a control (without being injected), saline, Morphine 1 mg/kg, morphine 10 mg/kg and morphine 50 mg/kg. They were studied. Movement measuring done after being injected by open filled. Mentioned groups in the previous experiment, In order to determine their previous induced sensitization, were reexamined 48 hours after being injected 1 mg/kg morphine.

Findings showed that the tissue thickness on the frontal cortex in stressed group was less than the control group (p<0.01) And also the number of stressed right handedness in males was less, but the number of left handedness in female ones was higher. Injection low dose morphine in experimental group had no effect, but in high dose caused induced motion activations. But this motion activity was much less than the control group. The low dose morphine injection (1 mg/Kg) in stressed groups caused induced motion activities which this action in dose 50mg/kg was significant statistically (** P<0/01).

Results showed that inducing a psychological relatively slight stress (a short-term restrain) could cause major changes, firstly in embryos brain and secondly in right handedness and left handedness and thirdly a response to morphine.
