Introduction: From a long time ago, benefiting from technology has been an inevitable thing for human interests, which is born and based on science. It can be claimed that there is harmony between ethics, science and technology, which promote each other. In this article, the researcher discusses this harmony and compatibility. Material and Methods: The current review study was descriptive and using the study of sources and research keywords among the books and articles published in the databases of Thomson Information Institute, Science Direct and Pub Med. Conclusion: As science and technology continue to advance and become more integrated into our daily lives, ethical considerations become increasingly important. For example, the rise of artificial intelligence (AI) has raised questions about the potential implications of creating machines that can make autonomous decisions and take actions. If science and technology were considered as a tool, it should have been able to subjugate humans and influence all aspects of behavior and values. While it has become a problem that eventually becomes aligned with morality by applying reason, and people now seek help from it as a tool.

Geocriticism with a focus on the subject of place is one of the fundamental concepts in literature, the study of place in literary works became more important, especially in the postmodern era because not only literature plays an important role in the representation of space, but also the presence of geography has expanded in approaches such as thematic and postcolonial criticism. In geocriticism, the relation between imagination and reality is considered, it is the author's experience which means this linked to the category of place, so the author's view of a particular place is considered. In other words, It is not the description of the real places that matters, but it's the author's imagination that makes up the geography of the work. This approach is also related to thematic criticism. The theme of time and space shifts has been particularly popular in the literature for ages, with characters searching for their lost identities, so they begin the journey to know themselves by shifting in space as well as time. Reza. Ghasemi, who is one of the contemporary Iranian writers living in France, deals with this issue in the novel The Nocturnal Harmony of Wood Orchestra. In the present article, with the descriptive-analytical processing, the story is analyzed relying on the opinions of Bertran Westphal, in the scope of geographical criticism. In this novel, a vivid and dynamic image of the city of Paris and Tehran is displayed for the active audience, because the place and time shift in this story is not linear and the author does this with his own logic and without confusion, but it is necessary for the reader to sort out this confusing tangle in order to reach the world represented by the narrator.

Background and aim: Improper dimensional changes in impression materials, including of additional silicone impression materials can cause the failure of prosthetic treatments. The aim of this study was to investigate the effect of different temperatures on the dimensional stability of polyvinyl siloxane impression material. Materials and methods: In this in vitro study, 99 Harmony medium (Elsodent-France) additional silicone impression were prepared according to the manufacturer's instructions. The impressions were kept in the environment with temperatures of 4, 25 and 40 C°. Then with time intervals: one hour, one day and one week after molding, plastering was done. The diameter, width and height of plaster casts were measured by S. D. M digital caliper. Dimensional changes were analyzed by Two Way ANOVA and POST HOC test Results: Changes in the diameter dimension,at the temperature of 25 °C at all times compared to each other and at 40 °C during 1 week compared to 1 hour and 1 day, there were significant differences. Changes in the width dimension,at 4°C, 1 hour compared to 1 day, at 25°C, 1 week compared to 1 hour and 1 day, and at 40°C, 1 hour compared to 1 week had a significant difference. Changes in the height dimension,at 25 °C and 40 °C, there were significant differences between 1 week compared to 1 hour and 1 day (p < 0. 05). Changes at 25 °C in 1 hour, 4 °C in 1 day and 4 °C in 1 week were within the clinical standard range (1. 5%). Conclusion: In the scope of the present study, it seems that the dimensional stability of the investigated additional silicone is influenced by the temperature of the storage environment and the impression time, and the best time and temperature is 1 hour and 25 °C.

South Africa shows some similarities 10 Iran in respect of revolution resources and social problems. Their problems and ways of solving could be useful for us. Besides observable harmony and function there are enough grounds for disharmony and dysfunction. Racial conflict and marked inequality provide the potential of conflict much more than in the USA. After more than 3 centuries, now the blacks have the power and with that, there arises the process of social comparison with whites, feeling relatively deprived and new wishes. As a result the crime is rising and the blacks tend to kill white farmers and rape white women, ete. Also the state tends to act in the same direction and reply to the wishes of voters 10 reduces the room for the whites. In turn, the whites are unhappy of course and tend to leave the country. But without them South Africa will become another country and loose rapidly its privilege in Africa and the world.

Response surface methodology is a common tool in optimizing processes. It mainly concerns situations when there is only one response of interest. However, many designed experiments often involve simultaneous optimization of several quality characteristics. This is called a Multiresponse Surface Optimization problem. A common approach in dealing with these problems is to apply desirability function approach combined with an optimization algorithm to determine the best settings of control variables. As the response surfaces are often nonlinear and complex a number of meta-heuristic search techniques have been widely for optimizing the objective function. Amongst these techniques genetic algorithm, simulated annealing, tabu search and hybridization of them have drawn a great deal of attention so far This study presents the use of harmony search algorithm for Multiresponse surface optimization. It is one of the recently developed meta-heuristic algorithms that has been successfully applied to several engineering problems. This music inspired heuristic is conceptualized from the musical process of searching for a perfect state of harmony. The performance of the algorithm is evaluated by an example from the literature. Results indicate the efficiency and outperformance of the method in comparison with some previously used methods.

This paper presents a social harmony search algorithm to solve optimization problems with continuous design variables. Although the Harmony Search (HS) algorithm (HSA) has proven its ability in finding near global regions within a reasonable time, it is rather inefficient in performing local search. The proposed method applies the harmony search optimizer for global optimization and normal distribution is employed to update the position of each design variable of a new harmony found by the first rule of the HS (memory consideration) in every stage to rapidly attain the feasible solution space. Normal distribution works as a global search in early iterations and as a local search in final iterations to improve HS in order to quickly converge and find better solutions. Various benchmark optimization problems are used to illustrate the effectiveness and robustness of the proposed method. Finally, the experimental results reveal the superiority of the proposed method in quick convergence and finding better solutions compared to the classic HS, its recently developed variants, and some other optimization algorithms.
