Abstract: Articles 454 and 455 of the Civil Code are ambiguous in terms of the examples of the "right of rescission", the examples of "the implied condition of prohibition of the customer in the assignment" and the meaning of the word "void"; however, the supreme court decision as a unified judicial precedent No. 810 dated 24/06/2021is also vague and outside the scope of the lawsuits. A court has described the option of violation of the payment of installments and the delivery of the goods upon rescission as an implicit prohibition of the customer's assignment, and has ruled on the invalidity of the possessions and eviction. But in similar lawsuits, another court, from the terms of the same contract, did not describe such a concept, and with a different interpretation of the law, ruled against the seller. The supreme court emphasized the intent of the contracting parties in the case of the right to rescind the contract and return of goods sold, by commenting on an implicit matter, and did not comment on the legal status of the possession of the seller, and believes that the owner's right of priority does not invalidate the condition and the right of rescission against the return of the goods. While, according to the opinion of the majority of late and contemporary jurisprudents, deduced from Articles 454 and 455 of the Civil Code, the customer's right of assignment in the contractual right of rescission is dependent null. Thus, since the implicit matter of the return of goods sold and the request for eviction is based on the request for the cancellation of the assignment, the decision of the court is logically voidable.

linking of futures studies with the tourism industry can create a suitable position for research in the field of urban tourism. The present study is seeking to analyze of key affecting propellants on the development of tourism in Rasht city with future studies approach. The present study in terms of purpose is qualitative and in terms of data collection method and final results is applied. To conduct this research, 34 factors were extracted as the main factors in 5 dimensions (environmental, socio-cultural, planning-institutional, infrastructure-welfare, economic) and Then the propellants factors were identified by using the Delphi method. For data analysis, the interaction analysis method was used in MICMAC software. The results of the study indicate that due to the distribution of variables, tourism development in the Rasht metropolis is unstable. Then the key factors were ranked that the variables of development of relations with neighbors, animal life, the existence of shopping centers, were ranked first to third, respectively. According to the studies conducted in this field, so far no study has been conducted in relation of tourism development futures studies in the studied area. Finally, four scenarios were presented for the future studies of the tourism industry in the Rasht metropolis.

The over-exploitation of groundwater has led to many problems in the country. Since groundwater level is a variable that varies over the time and place, it can be considered as a spatio-temporal dataset. The purpose of this study is to investigate the spatial-temporal variation of the groundwater level in Jask plain from 1997 to 2013 to determine the spatial trend of groundwater changes. First, interpolation was carried out based on the Kriging and the Radial Basis Functions (RBF), and then accuracy was evaluated using MBE, MAE and RMSE statistics. The findings suggested that, compared with RBF, Kriging can estimate groundwater levels more accurately in the study area. Consequently, for each time in the study period, a groundwater level map was produced based of the method. To identify the spatial variability of the groundwater level, R2 and Man-Kendall test were used. The results of the R2 statistics indicated a significant variation in the water level. Similarly, the results of the Man-Kendall test showed a decreasing trend in the north-to-northwest margin with a high intensity of nearly -1. Generally, in different parts of the study area, the process of change has a specific and meaningful pattern.

The effects of mulches on weeds and cucumber (Cucumis sativus L.) yield, examined by field experiment at Research Station of Tabriz University in 2012, based on randomized complete block designed with four replications. Treatments included four kinds of mulches such as transparent plastic, black plastic, wheat straw, paper and control (mulch free). Results showed that black plastic was the most successful in weeds control, so that up to one month after sowing time (the first time sampling), some weeds were controled 100 percent, and all traits were reduced in some others. Two monthes after sowing time (the second sampling time), also all traits of weeds presented under black plastic significantly were reduced. After block plastic, paper was very important in weed control. At bigening of the growth season, transparent plastic caused increases in weed growth, but increasing of temperature under this kind of mulch, during season, weeds were bleached. The effects of wheat straw on weeds control was not significant. Cucumber yield in mulch treatments significantly was increased, so that from 21.25 t/h in control were reached to 57.4, 47.7, and 36.65 t/h in transparent plastic, black plastic and paper, respectively. The results of this experiment showed that using of suitable mulch, by controlling of weeds improved cucumber performance.

This research aims at comparing the effectiveness of training skills of parents in problem solving and expressiveness on the social adaptation and educational progress of their children.This study was conducted randomly on 24 high school boys in Somehsara. The research method was semi- experimental proper to dimentions. The means of research were questionnaires relating to social adjustment of high school students (AISS) (Sinha and Sink, 1993). (b) the average of the lessons of these students in grade one in high school to analyze the achieved data, first the averages and standard deviations were used and then for testing hypothesis analysis of the variance of a few variables was used. The research results showed that the program of parents' expressing skill has had influence on the increasing of the social adaptation and educational achievement of their students. Problem solving skill has had influence on children's social adaptation, but it hasn't had any influence on their educational achievement. The Findings of this research can be applied to students` educational progress, growth and advancement of social adaptation
