Adipose tissue is a loose connective tissue distributed in two main anatomic depots including subcutaneous and visceral. Since in many pathological condition and diseases associated with adipose tissue alteration, the micro-components of adipose tissue undergoes considerable changes from mechanical characteristics point of view, it is quite vital to present an accurate structural technique for modelling tissue microstructure. Accordingly, this paper presents a structural model based on adipose tissue main components and interaction between them. Adipocytes was considered as a fluidic spheres and extracellular matrix modeled as solid media. The interaction between these two different phases simulated by solving well-known fluid-structure interaction (FSI) problem. In order to obtain the constitutive parameters for ECM, finite element simulation results fitted to experimental uniaxial compression test data. To make a comparison between the performances of different constitutive models, three conventional hyperelastic models were used for describing the mechanical behavior of ECM. The agreement between experimental data and simulation results confirm that the presented technique has a high potential for modeling adipose tissue microstructure both in normal and pathological condition. Considering the accuracy and mathematical complexity, results show that Yeoh hyperelastic model has a better performance than two others. In all three model, results reveals that the stiffness of adipose tissue ECM is ~ (2-3) times higher than that of the adipose tissue.

The significance of research article (RA) abstract as a key academic genre has recently motivated analysts to focus on this neglected area. Considering a summary function for abstracts, most genre researchers have adopted the conventionally proposed Introduction- Method- Results- Discussion (or Conclusion) (IMRD) model for analysis. However, the problems reported, especially for Results and Discussion sections, question the vitality of such accounts and prompt further scrutiny. Moreover, in spite of claims about disciplinary and cultural variations which can affect communication within and across discourse communities, sufficient contrastive studies which address the Iranian academics' need to communicate with and participate efficiently in the international discourse communities are scarce. Inspired by English for Specific/Academic Purposes tradition of genre analysis, this paper tries to fill these gaps presenting a comparative generic analysis of soft sciences abstracts to see what the characterizing features of the texts of Iranian scholars and their international peers are. The macro-structure, micro-structure, and some features of 100 experimental RA abstracts taken from a number of reputable Iranian (Persian) and international (English) journals were analyzed and explained drawing upon some existing rigorous models. The results revealed similarities in the presence of Introduction, Method, and concluding units, while there were also differences in the realization of units, Moves, and Steps. It is argued that the differences can point to the varying cultural norms and values of the two groups. Plus, considering the inadequacy of the four-way macro-model, an alternative three-way model was suggested, instead. Some implications of the study are discussed, too
