The objective of the present study investigated on the effects Mellissa officinalis seeds\nexposure to magnetic fields on seed germination, early growth and enzyme activity,\nunder laboratory conditions Mellissa officinalis seeds \n(\ndry and wet\n)\n were studied after\ntreating with different intensities of magnetic field \n(\n0, 25, 50 and 75 mT\n)\nand exposure\ntime \n(\n0, 30 and 60 min\n)\n. There were significant effects among treatments for\ngermination percentage, root length, shoot length, seedling dry mass and seedling vigor\nindex in Mellissa officinalis seeds under different magnetic intensity. In the germinating\nseeds enzyme activities of α-amylase, dehydrogenase and protease were significantly\nhigher in treated seeds in contrast to controls.
Recently, as robots and human have started to share daily life with each other, an interaction between human and robot is being highlighted because of these share and proximity. Thus, in order to make a safe interaction among them, it will be essential to optimize the abilities of robot by adding a pain detection system in it. In this paper, based on the skin functions, we present a set of design criteria for how “thermal pain detecting system” should be designed. The objective of this study is to determine the process of perception pain intensity in human, so we would be able to implement this complex process in robots. Thus by implementing this system in robots or other machines, they would have the capability to sense, think and react automatically to be safe in hazard situations. The fuzzy logic controller provides a means of converting a linguistic control strategy based on expert knowledge into an automatic control strategy. The first aim of this study is to analyse the heat transfer problem in skin tissue based on Pennes bioheat equation by using biological data. Afterward, we have simulated the skin behavior to design and implement this system in robots. Finally, to emulate the thermal pain, we have designed a controller based on the thermal pain model and also apply this controller system in robot finger which is designed in Matlab software. The results of this study show that by applying this system, robot behavior can be one step closer to human behavior.

This study is an applied and correlational study. The target population included all the employees (150) working in Narges Hospital, Iran, out of which 108 were selected randomly using the Krejcie and Morgan table. Content and face validity of the questionnaire was confirmed content analysis of the constructs. Reliability of the measurement was also estimated by Cronbach Alpha and found to be 0.86. The data were collected using a questionnaire and analyzed using descriptive and inferential statistics and regression analysis using SPSS software. The results showed that job characteristics and fair treatment with the employees had a higher relationship with overall job satisfaction compared to customers’ satisfaction. On the other hand, customers’ satisfaction did not have a larger effect on emotional commitment to the organization under study compared to overall job satisfaction. In addition, emotional commitment affected the attraction of potential customers but did not influence attraction of employees

Objective: the objective of the present study was to investigate the effect of combining aqueous extract of saffron and aerobic training on the concentration of blood non-enzymatic antioxidants in the STZ-diabetic rats.\nMethodology: 41 male rats (age: 12 weeks, weight: 314±26.7 gr) were randomly assigned to five groups 1.healthy-control (HC, n=6), 2.diabetic- control (DC, n=10), 3.diabetic-aerobic training (DAT, n=10), 4.diabetic-saffron (DS, n=10) and 5.diabetic-aerobic training-saffron (DATS, n=5). Except group 1, other groups were diabetic by injecting STZ. The 4 and 5 groups orally received 25 mg/kg aqueous extract of saffron for two weeks on a daily basis. The 2 and 3 groups ran on a treadmill for two weeks, five consecutive sessions, with the speed of 12 m/min and slope of 0% for 30 min. 24hours after the last session of exercise, the rats were anesthetizing by chloroform and sacrificed, the chest was cut, the blood was taken straight from their hearts, the blood sample was centrifuged with the speed of 2000 rounds a minute for ten minutes and blood plasma was separated in order to determine the concentration of malondialdehyde (MDA), glutation (GSH) and total antioxidant capacity (TAC). \nResults: Analysis of variance (ANOVA) showed significant differences between the five groups at the levels of malondialdehyde, glutation and TAC (P= 0.001). The results of the Scheffe post hoc test demonstrated that the concentration of malondialdehyde had a significant decrease in the saffron-aerobic training (P= 0.001), diabetic-aerobic training (P= 0.001) and saffron-diabetic (P=0.001) groups compared with the diabetic- control group. The concentration of glutation had the most and least increase in the saffron-aerobic training and diabetic- control groups, respectively (P= 0.012). The concentration of TAC had the most and least increase in the saffron-aerobic training and diabetic- control groups, respectively (P=0.005). \nConclusion:\nThe results of the present study demonstrated that the combination of saffron extract and aerobic training would be appropriate method for reinforcing the blood non-enzymatic antioxidant system in diabetic rats.
Most of the international relations theories explain that states form military alliances in response to common external threats. Conversely, alliances should disintegrate when the threats that occasioned their formation disappear. When the cold war ended in Europe, many observers ex¬pected that NATO\'s demise would soon follow. Even if the alliance did not disappear altogether, it would become an empty shell, no longer performing any useful functions. However, NATO has not become moribund. However, NATO has not only survived but has even added to its elaborate organizational bodies and undertaken new activities. We discuss in this article about Theoretical foundation expansion NATO after cold war. \n\nKeyword:
