Dear Hema,
I hope you are not serious with your request. Scholarly articles published if not available on the net for free have to be obtained after paying for the same. One of the conditions when bought is that it is not copied and sent to others, as authors and publishers lose money. The mere fact that the two posts above yours did not get any responses clearly shows that no one at CiteHR was able to provide the necessary articles. It also happens that people who start their PhD change their mind and drop out, like one I helped did.
Could you also please tell us where you are doing your PhD and in what mode?
Have a nice day.

Hence, I suggest that you search the web and write to the authors of articles yourself and they may help.
