Effect of chemical control of weeds on yield and yield components of rapeseed in Ahvaz region

To investigate the effect of chemical control of weeds on yield and yield components of rapeseed in Ahvaz region, a split-plot experiment was conducted in a randomized complete block design with four replications in 2012. The main factor in this experiment was 6 treatments including: control without the weed, application of Trifluralin herbicide, 2.5 liter per hectare pre planting, Butisan Star herbicide, 2.5 liters per hectare of the crop, Pre-emergence, Sethoxydim herbicide, 3 liters per hectare, Lonetral herbicide; 0.9 liters per hectare and control with the weed and the sub-factor included two cultivars of rapeseed (Hyola 308 and Hyola 401). The results showed that control treatment and Hyola 401 had the highest yield, and among the herbicides Trifluralin herbicide improved yield of rapeseed by better control of the weed. This fact shows high adaptability of Hyola 401 to the climate of Khuzestan (Iran) and also high ability of Trifluralin in controlling weeds in rapeseed

Association of Decorative Elements in Haj Agha Ali House, the Largest Adobe House in the World

Historical houses in Qajar era are among the most significant works of that time which represent specific features of that time having a close relationship with daily life of people. The houses are important for their plans and architectural spaces and they are also culturally and aesthetically unique because they contain many decoration and elements which are treasures of art and handicrafts.  In this development, research was conducted in a library. Here motifs used in Haj Agha Ali house have been categorized after analysis and comparison. In fact, decoration is an integral part of traditional architecture in Iran as they show the type of using space and they also represent the dominant mind set of that time. Qajar art as occasion served was exposed with western elements and reacted upon them. The result of such reaction in architectural decoration is that in many cases imported elements are created with traditional elements in an associated combination. Although in some cases, the full unity is not the case but generally, the artists of that time could get to a general unity in architectural decorations with a combination of different cultural elements. Because there have been no comprehensive studies about the decorations of the house, the present study can introduce aesthetics features and concepts and open the doors of modern plans for the younger generations

Strategic evaluation and analysis of improving the level of loyalty in tourism destinations (Case: Study: Yazd city)

Introduction: Loyalty of a tourist to a specific destination is a key issue in urban tourism management. A high level of loyalty in a destination can have positive consequences for the development of tourism in that region. One of the important topics in this field is the strategic measurement and analysis of the level of tourism loyalty in different dimensions and components and providing strategies to improve it. In the meantime, measuring the goals, capabilities of cities, and the opportunities and challenges ahead in the field of tourism loyalty and knowing the competitors of the destination are taken into account for the strategic analysis of tourism loyalty. As one of the urban tourism destinations of Iran, the city of Yazd attracts a large number of domestic and foreign tourists every year with its many tourist spaces and products. the main goal of the research is to provide strategies for the development of the loyalty level of Yazd city through the recognition and evaluation of the objectives, capabilities, opportunities, challenges and competitors of the city's tourism and evaluating its strategic suitability.Data and Method: the current research is applied in terms of its purpose and descriptive of the survey type based on its nature and method. The required data is prepared based on the library and field method. The statistical sample of the research was 30 people from the group of experts, including officials and managers of tourism, researchers and researchers, owners of tourism businesses, and a number of residents with a history of the city, which due to the limited statistical population, the whole number method was used to get samples. became. For the strategic analysis of the research, Meta-SWOT analytical model, which is an advanced SWOT model, has been used.Results: The results showed that the most important resources and capabilities in order to improve the level of tourism loyalty in the city of Yazd include the positive effects of the globalization of the city of Yazd on improving the character of the city and its historical attractions, changing the positive mentality of tourists towards the city, understanding its scientific and historical value. And to arouse their feelings, to raise the quality of services, relative participation of citizens in social and tourism programs, acceptable tourism security and urban infrastructure and services, agency services and health tourism ConclusionThe result of the strategic analysis shows the greater homogeneity of Yazd's tourism capabilities and external factors and goals in terms of strategic fit, and the aforementioned capabilities play an important role in improving the level of loyalty at a medium level, and based on this, solutions have been presented to improve it

Protective effect of perserved solutions of Krebs contains verapamil, adrenaline and propranololol in comparision with Krebs and Heparinated blood on desqumation of the endothelial cell in Saphenous vein of Guinea pig

Background and Objective: The most important factor in the integrity of saphenous vein is the health degree of endothelium which guaranties the dilation of them after cronary bypass sergery. Kind of preservative soulution has a key role in endothelial protection. This study was done to evaluate Protective effect of perserved solutions of krebs contains verapamil, adrenaline and propranololol in comparision with Krebs and Heparinated blood on desqumation of the endothelial cell in Saphenous vein of Guinea pig. Methods: This experimental study was done on 28 male Guinea pigs with 380±40g weight.for separating 3mm of saphenous vein rings and Measuring of rings nitric oxide released in preserving solutions: Krebs (K), Krebs plus propranolol (K+P), adrenaline (K+A) and verapamil (K+V) compaired with heparinized blood at 30, 45, 60 and 90 minutes after harvesting measured by micro plate Griess reaction. Rings also stained by H&E and examined by light microscopy to evaluate endothelial desqumation. Results: Average concentration of nitric oxide (NO) in the Krebs plus Verapamil solution (K+V) Vs Heparinized Blood (HB), Krebs (K), Krebs plus Adrenaline (K+A) and Krebs plus Propanololol (K+P) revealed significant increase in NO release (P<0.05). The maximum NO measurement was 45 minuts after harvesting. Also histological study with H&E staining showed that endothelial layer was intact only in Krebs plus verapamil in compaired to control group, but in the other solutions the vascular intimal cells had suffered different degrees. Conclusion: It seems that Krebs solutions containing verapamil has more efficiently to the proper functioning of the saphenous veins endothelium in animal modle
