No journal is having any power or authority to reject any research.

They may reject an article on various grounds related with publication of the article.

Thanks.

reasons are many. Here aresome

1. A manuscript scope different from that of the global journa

2. Failure by authors to format and present tthe manuscript in accordance with journal guidelines

3. Poor presentation of manuscript

4. Lack of novelty in the study

5. In appropriate statistical analysis

6. Lack of international relevance in the manusript

Probable reasons are:

1. Suitability

2. Results violating the basic principles

3. Research methods may not be proper

4. Any kind of conflict

5. Repetitive research and plagiarism

The topic does not match the journal's goals, the language is not good, the idea of research is old and bad luck. These probably represent some of the reasons for which the researches are rejected by reputable journals.

Awesome notes

If no explanation is given, then the editor doesn't agree with your ideas.

Our journal rejects the paper for the following reasons:

- The paper topic is not in correspondence with the journal topics.

- Very bad English

- Paper is poorly exposed (the title does not reflect on the subject, explanations not logical and unscientific, curves that does not correspond to the literature, ...)

- The percentage of plagia is very high.

- The author is on the black list of the journal.

Interesting

In an ideal world research papers should be rejected if the work presented is of low quality, or if the style of presentation is much below standard.

In many cases not being related to the scope of the journal cause rejection in the very first phase by the editors. Other reasons could be low quality, not having enough contribution, or not being able to elaborate your contribution adequately and properly.

1) Manuscript is not in scope of the journal; 2) the language is not good; 3) the regulations for formatting the manuscript are not according to the journal guidelines.

The subject of the paper would not attract new readers.

* All previous answers are excellent and fruitful.

** However, I met some "traders" Journals that refuse the suggestion of new interesting equations in Applied Sciences. They say clearly that they prefer new experimental data to disseminate more volumes and issues.

*** Others refuse the publication of new findings because they have no theoretical precedents, despite it are verified by several systems!

I agree with Abdullah Noori
