Despite various comparative studies in the field of cultural heritage protection in the world, there is still a significant lack of comparative research on policies related to the legal system of countries' governance. The purpose of this study is to address the comparative policies in Iran and Italy, with a particular focus on the results of the executive experiences of two different types of policies in the cities of Oroumieh (North-West of Iran) and Turin (in North-West of Italy).

Utilising the comparative, analytical, bibliographic and descriptive historical research methodology, which is based on the study of the local, national and international comprehensive review of regulations and policy-making of cultural heritage preservation policies in Iran and Italy. In this research, the related documents in three languages (Persian, Italian and English) have been examined to compare profoundly and comprehensively the policies and regulations adopted in these two countries to be able to analyze the national and transnational regulations and local policies in the cultural heritage sector.

In addition to many cultural similarities and numerous commonalities, especially in the multiplicity of urban cultural heritage in historical centers, the results suggest that the legislation structure in Iran is much more centralized than in Italy. Also, the findings suggest that Italy focuses on aligning its previously centralized national legislative system in line with contemporary European heritage and preservation policies.

The paper outlines how to use historical and cultural similarities through comparative study to benefit the experiences of two historical countries in urban heritage conservation and policy-making part despite their differences.

This paper aims to Separation and sorting of biological cells is desirable in many applications for analyzing cell properties, such as disease diagnostics, drugs delivery, chemical processing and therapeutics.

Acoustic energy-based bioparticle separation is a simple, viable, bio-compatible and contact-less technique using, which can separate the bioparticles based on their density and size, with-out labeling the sample particles.

Conventionally available bioparticle separation techniques as fluorescence and immunomagnetic may cause a serious threat to the life of the cells due to various compatibility issues. Moreover, they also require an extra pre-processing labeling step. Contrarily, label-free separation can be considered as an alternative solution to the traditional bio-particle separation methods, due to their simpler operating principles and lower cost constraints. Acoustic based particle separation methods have captured a lot of attention among the other reported label-free particle separation techniques because of the numerous advantages it offers.

This study tries to briefly cover the developments of different acoustic-based particle separation techniques over the years. Unlike the conventional surveys on general bioparticles separation, this study is focused particularly on the acoustic-based particle separation. The study would provide a comprehensive guide for the future researchers especially working in the field of the acoustics, in studying and designing the acoustic-based particle separation techniques.

The study insights a brief theory of different types of acoustic waves and their interaction with the bioparticles is considered, followed by acoustic-based particle separation devices reported till the date. The integration of acoustic-based separation techniques with other methods and with each other is also discussed. Finally, all major aspects like the approach, and productivity, etc., of the adopted acoustic particle separation methods are sketched in this article.
