While publishing a scientific article, even though it satisfied the aim & scope of the journal, a scientific paper rejected by one journal is accepted by another one journal. is there peer review process not effective or reviewers not ideal.
1. A large number of similar papers have been submitted or published recently in the journal and therefore the article is being rejected bu the journal. The second journal does accept the article as there are not similar articles.
2-It all depends on reviewers, The same article can have different fate with different reviewers!.
It depends... The article may be, in general, good, but sometimes, you are "lucky" with reviewers in one journal and "less lucky" in another (e.g. in terms of how well they understand your topic, methods etc. and if they consider your topic, theoretical/empirical contribution, data/methods... important/original), also, some editors may have different preferences regarding methods, topics, studied countries etc. So, if you get rejected from a journal, read the reviews, learn what you can and change what is reasonable to change and then, send the paper elsewhere.

The peer review process is not perfect but it is the best thing we have. Good journals have better peer reviewers and will use at least two, with an editor overseeing the reviews to ensure some degree of quality.
You also need to take into account the quality and reach of the journal, whether they have already published similar papers recently, if they are looking for items for a special issue, and how well a submitted article builds on articles already published in that journal. Once you select a journal I would always recommend looking at articles published in the last 10 years which might be relevant using keyword searches.
Why not offer to become a reviewer yourself? It would help you to understand the peer review process from the inside.
When ever your article is related to scope of the corresponding journal,it will be accepted easy. if the article not met the scope and aim it'll be rejected.
