  Today, the situation of urbanization and informal settlement in the world and its theories and experiences contain clear and useful points. While statistics indicate a growing urban population, especially in developing countries, poverty is seen as one of the most important aspects of population concentration in the cities of these countries. The main objective of the present study is to identify, in the first place, the indicators of empowerment of informal settlements with an emphasis on the concept of an asset-based approach as a new approach in contrast to the need-based approach and, secondly, to measure extractive indicators in order to understand the impact of each One of the satisfaction of inhabitants of these settlements is the living conditions and the role of each indicator in improving their living conditions. The study area of ​​the study is the Interobhab district of Islamshahr, which in the year 1395 was about 24 thousand people. At the end of 2007 and beginning of 2008, about 45 thousand people lived in Mid Abad. The method used in the research is based on documentary, surveying and analytical combination. The results of the research indicate that the correlation in the residential building subsystem related to the capital capital index is higher than the rest, and then sub-index of monthly income The financial need index corresponds to the highest level of solidarity with the residents' satisfaction with informal settlements. After these two sub-indicators, we can say that the highest scores refer to sub-indicators of social capital index such as: accountability, trust, participation, institutional capacity.

  Differential scanning calorimetry (DSC) is widely used to determine the crystallinity of semicrystalline polymers. In the two-phase model, the measured heat of fusion is compared to the melting enthalpy of a completely crystalline polymer to get the crystallinity degree. Fusion heat of a polymeric sample is identified by area under the melting endotherm and a baseline. A correct baseline is heat capacity of the semicrystalline sample. It varies with both temperature and crystallinity and is difficult to evaluate. Enthalpy of a process is a state-function quantity and is independent of the process path. In polymer melting, temperature increase and fusion process occur simultaneously. This makes evaluation of the fusion heat challenging. Herein, alternative paths are supposed in which temperature increase and fusion process occur separately and sequentially. This leads to a convenient enthalpy evaluation. Two alternative paths can be defined: first, polymer melts at a constant temperature which is followed by temperature increase of the melt; second, polymer temperature increases without any change in crystallinity degree which is followed by polymer melting at a constant temperature. Lastly, an enthalpy deficiency due to the amorphous-crystalline interface and an excess enthalpy due to the defects present in crystalline regions are investigated how to affect the crystallinity.
