Abstract Background Brown plant hopper (Nilaparvata lugens Stal.) a very damaging pest to rice crops. One of the efforts control it is use entomopathogenic fungi (EPF). Three fungal local isolates found in Indonesia were effective controlling brown pest. This study aimed molecularly identify 3 isolates. Molecular identification important get exact identity these fungi. The accuracy EPF will gre...
Developing countries offer potentially some of the most important growth opportunities for companies both from the developing as the developed world. It is therefore interesting to note that a recent review of the last twenty years of empirical research grounded in institutional theory found that most studies focused on developed countries (95 percent) and that only a small portion (five percen...

An unstable discharge rate occurs during dry fine powder from a hopper because of the significant two-phase solid/gas interactions that occur in flows. In addition, air bubble phenomenon may silo discharge. this study, we conducted experiments using semi-conical dual-structure hopper, and examined effects on internal flow structure, cavity fluid pressure, pressure inside airtight section, when ...
