Other red flags are evident. First, aside from Moinuddin Sarker, the editorial board of this "American Journal of Engineering" is devoid of editors from the United States. (Good journals need not have US editors, but one has to wonder about the honesty of an "American journal" that has such tenuous connections with America.)
Second, it is not clear how many of the editors are engineers. One is a postdoc (polymer science) at Shah abdul Latif University in Pakistan. Others specialize in such subjects as animal breeding, genitourinary tumors, health and epidemiology, hypoxia, and "Logic, Philosophy of Maths and African Science."
Third, the journal touts its inclusion in the American National Engineering Database (and in no other indexing service). ANED has been described as a "fake database by fake publisher" in India.
Fourth, the journal promises peer review within a week. Competent peer review within a week is not routinely possible.
Finally, AJER insists that it is an "official international journal," whatever that means.
