This study evaluated the quantitative and qualitative traits of 13 local summer squash populations. The experiment was carried out in a randomized block design with 3 replications for two years (2019 to 2020). The following traits were considered in this study: number, weight, length, width, and length/width ratio of fruits, seed yield, seed yield/fruit yield ratio, 1000 seeds weight, percentage of empty seeds, seed length, seed width, seed kernel/whole seed ratio, and seed oil percent. Also, quality tests were conducted including ease of separation of skin from the kernel, taste quality, and desirability of seed shape and size from the consumer's point of view. The analysis of variance showed significant differences in most of the studied traits. Based on the results of the mean comparison of traits, the highest seed yield was observed in Ghalami-Kalaleh#1 and Mashhady-Azadshahr and then Mashhady-Khoy populations. The highest taste quality from the consumer point of view belonged to the Goushti-Kalaleh population. The results represent a positive and highly significant correlation between seed yield and fruit number. No significant correlation was observed between seed yield and other related traits. It is recommended that fruit number trait be considered in selecting programs and modifying high-yielding populations.

Multiple sclerosis is one of the most common neurological diseases and affects various aspects of a personchr('39')s life. The aim of this study was to compare the cognitive fusion, self-compassion and flourishing in patients with multiple sclerosis (MS) and normal individuals.

The research design was descriptive and comparative. The statistical population included all patients with MS under the supervision of the Mashhad MS Association in 2020, from which 40 people were selected by purposive sampling. For the normal group, 40 normal people matched to patient group were selected. The instruments used in this study were the cognitive fusion questionnaire of Gilanders et al, self-compassion questionnaire of Neff and Diener, Biswas-Diener Flourishing questionnaire. The collected data were analyzed with multivariate analysis of variance and logistic regression using SPSS-24.

The results of the present study showed that the mean scores of cognitive fusions in patients with multiple sclerosis (40.87±5.69) was higher than normal individuals (14.5±5.22), the mean scores of self-compassions in patients with multiple sclerosis (39.72±7.84) was less than normal people (76±9.53) and the mean score of flourishing in patients with multiple sclerosis (25.7±7.76) was less than normal people (47.42±5.75) (p<0.05). The results of logistic regression showed that cognitive fusion, self-compassion and flourishing predicted MS.

Based on the results of the present study patients with MS have higher cognitive fusion and lower self-compassion and flourishing than normal people. Given that psychological factors play an important role in the quality of life and improve performance of these people, it is necessary for counselors and therapists to consider the importance of psychological factors during the treatment of this disease.

Fragility curves provide damage probability as a function of ground motion characteristics and design parameters. In this study, we developed fragility curves for the precast reinforced concrete system, used in the construction of buildings in some high earthquake-prone zones in Iran. For accurate seismic demand estimation, we developed a numerical model for the precast beam-to-column connection based on the experimental results presented in the relative research. Incremental Dynamic Analysis (IDA) of the 3 and 5-story frames was conducted under the appropriate ground motion records set. The records database includes 10 far-fault records and10 near-fault records in which 5 records have pulses and 5 records do not have pulses. In IDA, multiple nonlinear dynamic analyses of the frames were performed using the OpenSees software under the ground motion records, each record scaled to several levels of seismic intensity from 0.1g up to the level at which structural collapse occurred. Based on the IDA results, the median and standard deviation values for the construction of the fragility curves were proposed at the four damage states of slight, moderate, extensive and complete. Results demonstrate that for a given seismic intensity level, the precast frames are more seismic vulnerable than the cast-in-place moment resisting frames. At a given level of seismic intensity, seismic vulnerability at four damage sates increases with increasing the height of the frames. The probability of exceeding the complete damage state at the design earthquake level was obtained to be 0.56 and 0.63 for the 3 and 5-story precast concrete frames, respectively.Considering that incremental dynamic analysis requires large computation efforts, we evaluated the possibility of using the static pushover analysis (SPO) in the development of fragility curves. For this purpose, the fragility curves were derived based on the pushover curves using the SPO2IDA algorithm. The results show that for all considered models at four damage states, the SPO method provides an acceptable approximation of the fragility curves. The accuracy of the SPO method in the development of fragility curves is improved at higher levels of response. The fragility curve of the 3 and 5-story frames for the complete damage state, developed based on the SPO method, is about 8 percent more than the corresponding curve obtained from the IDA method. Generally, for all structural models and all damage states the probability of exceedance obtained from the SPO method is about 12 percent more than that obtained from the IDA method.
