stem cells are undifferentiated self regenerating multi potential cells. there are three types of stem cells categories by the ability to form after cells and correlated with the body’s development process. totipotent: these stem cells can form an entire organism such as fertilized egg. ploripotent: ploripotent cells are those that can form any cell in the body but cannot form an entire organis...

the highly substituted pyridine derivatives are found to exhibit diverse pharmacological activities. they are also emerged as potential medicinal leads in developing therapeutic agents for the treatment of various diseases. in this work, a series of 2-amino-3,5-dicarbonitrile-6-thio-pyridine derivatives have been synthesized at room temperature via one-pot, multi-component reaction of various a...

green space, as a social development indicator has environmental, social, cultural, economical, and skeletal aspects and to be able to play its role effectively, the first and most important step is to select an appropriate site for it. site selection necessitates stability analysis of urban green space. the main three steps are identifying stability factors, ahp-based weighting factors and lay...

this research is aimed at developing a model for measuring and comparison amount of supply and demand for different urban services from quality of life and equity perspectives, in urban built-up areas. this paper explains different steps of implementing the model as a tool for evaluating accessibility of residents to various services according to two main criteria: land per capita and distance ...

In order to achieve the large-scale reductions in carbon emissions necessary to reduce the impact of climate change, fundamental technological changes will be required. In this regard, Green IT and IS may be able to play a pivotal role; however, such initiatives require new skills of IS leaders that are not sufficiently addressed in current university programs. In the process of developing prac...

Multi-component coupling reaction (MCR) is a powerful synthetic tool for the synthesis of biologically active compounds. Development of such multi-component coupling reaction strategies in visible light has been of considerable interest, as they provide simple and rapid access to a large number of organic molecules through a sustainable path. An efficient and green protocol for the synthesis of...
