Abstract The element free Galerkin (EFG) method, which is based on the moving least square (MLS) approximation, requires only nodal data and no element connectivity. These features make the method more flexible than the conventional FEM. Nevertheless, direct imposition of the essential boundary conditions in the EFG method is always difficult because the shape functions obtained from the MLS approximation do not have the Kronocker-delta property. A new method named "the complementary integral method" is proposed here to overcome this difficulty. The presented method is more consistent with the variational basis of the EFG method. Several numerical examples are used to illustrate the implementation and performance of the method. The numerical examples including the Poisson's equation and 2D static and dynamic elasticity problems show that the method converges fast with reasonably accurate result for both the unknown variables and its derivatives.

Aims: Modernization theory today, as one of the newest theories, suggests the application of contemporary architecture in the process of action in valuable cultural and historical contexts. The most challenging issue among these is to identify the differences and similarities of this theory with other competing opinions and analyze its strengths and weaknesses. The main goal of the research is to reread the theory of contemporization for adding quality to the old textures through the experience of creating value for the heritage of contemporary architecture.

Methods: The current research strategy is logical reasoning strategy. It is a descriptive-analytical research method that uses the tactic of comparative comparison to advance the research process. The theoretical framework of the research is a combination of the master architecture theory and the theory of contemporization. Hence, the research analyzes and rereads the strengths and weaknesses of the theory of contemporization by comparing competing theories.

Findings: The analysis of research findings in two fields including the field of formal system (physical-structural system) and content system (1- economic, 2- social system and 3- environmental system) shows that the theory of contemporization can be better than the theory competitors such as reconstruction, renovation, improvement and regeneration; In the category of quality, it acts as a part of historical and cultural contexts and increases the quality of life of the residents.

Conclusion: The results of the research show that the theory of contemporization by emphasizing the design approaches and values of contemporary architecture increases the quality of historical and cultural contexts; Along with simultaneous emphasis on formal system and content system.

which have lost their main functions, and their abandonment and lack of proper use causes them to be destroyed more and more. Nowadays, historical buildings can no longer be used as in the past and by changing the use of historical buildings, they are saved from certain death, and the concept of contemporizing all these achievements is in mind.

Methods: In this study, the time range is related to the traditional houses located in the neighborhoods of Tehran in the period from 1941 to 1966., most of the houses are related to the central core of Tehran and the surrounding and neighborhood streets of Elginab, Waliasr, Karim Khan Zand, etc. The techniques used in the applied method of this research in order to modernize modern historical monuments are preparing and completing the questionnaire, using the interpretive structural modeling (ISM) approach and linear regression technique.

Findings: Among the 42 indicators studied in the five physical-structural, perceptual, functional, socio-economic and natural-environmental dimensions, the indicators of preserving old residents, improving the quality of housing, using special colors, easy access on foot, etc. are completely inappropriate conditions in terms of the principles of modernization They play a role in the historical monuments of Tehran metropolis.

Conclusion: The four indicators of neighborhood authenticity and sense of belonging, the use of a special form, the presence of necessary activities and the recognizability of spaces have the highest and best quality compared to other studied indicators from the point of view of the theory of contemporization, and they have medium-high conditions in terms of the points obtained.

Although chemotherapy is one of the effective methods in cancer treatment its effects may be moderated due to drug resistance. The main objective of this paper is to propose optimal finite cancer treatment duration. In this paper, a mathematical model of tumor growth by adding radiotherapy, chemotherapy and metastasis of cancer cells terms is extended. Stability analysis shows that the tumor free equilibrium point is unstable. Hence, changing the dynamics of the system around this equilibrium point for achieving finite duration treatment method is essential. Therefore, the effects of chemotherapy drug are considered not only on cells populations but also on the dynamics of the system. For this purposes, State Dependent Riccati Equation (SDRE) based optimal control is used. So chemotherapy agent is used as the control input to the extended cancer nonlinear model. Then, in order to show the flexibility in design, two different types of input weighting matrices are selected. Moreover, the robustness of this control method is investigated by simulation. Results show that changing the dynamics of the system is necessary for finite duration cancer treatment method.

La langue et la culture sont indissociables, car la culture se manifeste dans la langue et grâce à cette dernière, pourrait être fournie la base nécessaire à la manifestation de la culture. La traduction est un discours socioculturel où les sociétés humaines pourront afficher leur identité culturelle en invoquant l'autre. La problématique principale autour de laquelle s’organise cette recherche est celle de savoir comment dans la traduction, les culturèmes provoquent le déplacement des frontières sémantiques et comment l’union entre le nous et les autres, comme l’explique Y. Lotman dans la théorie de la sémiosphère, serait possible.  Cette recherche aura pour objectif de montrer que dans la traduction du roman Papillon, la transmission du sens des culturèmes dépend des situations discursives fondées sur deux systèmes sémantiques convergents et divergents. La présente étude est fondée sur l'analyse du corpus c’est-à-dire le roman Papillon d’Henry Charrier traduit par Parviz Naghibi. Ainsi les données principales de la recherche seront collectées à partir du corpus. Après avoir analysé les stratégies du traducteur, nous chercherons à apporter des solutions pour la bonne transmission du sens des culturèmes dans le processus de traduction. Enfin, nous essayerons de déterminer les typologies de traduction des culturèmes du point de vue de J. Fontanille. Les résultats de cette recherche indiquent que le traducteur n’a pas réussi à transférer le sens des culturèmes, car en adoptant des stratégies qui ne sont pas convenables pour traduire des éléments culturels d’une langue à l’autre, il n’a pas essayé de réduire les distances entre le nous et l’autre.

The sensitivity of the moving platform of parallel mechanisms to the uncertainties in the design and control stages is of paramount importance. The mechanism has to be designed such that the negative effect of the foregoing errors is minimized. The latter issue has encouraged many researchers to derive and propose relevant indices being responsible for outputting a metric representing the kinetostatic performance of parallel mechanisms. Most of such indices entail severe drawbacks in the sense of leading to physically inapplicable interpretation, which was considerably alleviated by the emergence of kinematic sensitivity. Nevertheless, none of the studies heretofore has investigated the influence of the uncertainties in the passive joints on the kinetostatic performance. In other words, the assumption has always been that the aforementioned errors are negligible. This paper proposes a novel formulation for the kinematic sensitivity index, which, apart from that of the active joints, takes the effect of the uncertainties in the passive joints into account, and brings about the advantage that the mechanism can be optimized and improved in terms of kinetostatic performance, together with the workspace. The formulation, for the sake of illustration and verification, is also applied to the 4-bar linkage and 3-RPR parallel mechanisms, as well as the Tripteron robot. The results of the implementation of the proposed kinematic sensitivity index, which takes the effect of the uncertainties in the passive joints into account, show that the values associated with the case-studies considered in this paper fall within the intervals 1-2.4, 0.1-0.9 and 0.6-2.2, respectively.

The use of medicinal plants in food has a long history. Flaxseed oil and eucalyptus essential oil are highly regarded due to their biological properties. In this research, the aim is to investigate the antimicrobial properties of zein nanofibers containing flaxseed oil and eucalyptus essential oil to control staphylococcus aureus and escherichia coli bacteria in a laboratory environment. For this purpose, flaxseed oil mixed with eucalyptus essential oil in zein solution. Then, it was converted into nanofibers using an electrospinning machine. In order to study the characteristics and antimicrobial properties of the nanofibers, tests including scanning electron microscopy (SEM), fiber diameter determination with Image J software, atomic force microscopy (AFM), X-ray diffraction (XRD), thermal gravimetric analysis (TGA) were performed. Investigation of antimicrobial properties of produced nanofibers by disk diffusion method were performed. The SEM results showed that the morphology of the electrospun fibers was uniform and free of beads. AFM images represented three-dimensional and tubular images of fibers obtained from electrospinning zein/flaxseed oil/eucalyptus essential oil. The X-ray diffraction pattern showed an increase in the crystallinity intensity of the treatments compared to the control sample. Based on thermal analysis results, eucalyptus and flaxseed oil increased the thermal stability of zein nanofibers. The results showed that the addition of flaxseed oil to eucalyptus essential oil strengthened the antimicrobial properties of nanofibers. According to the results of the present research, the zein/flaxseed oil/eucalyptus essential oil fibers can be used as natural antimicrobials.
