Hello and thank you for interesting to the topic
Every day we read a lot of articles in different fields. Sometimes we have some questions about them a lot of which can be answered by ourselves. But there are some obscurities or questions only corresponding authors can answer. Although a lot of them have admirable responsibility a few of them don't answer you at all. What do you think is the best treatment with them? Do you think sending an Email and report to the journal is a good way? or you suggest other solutions?
