The rapid propagation of Eichhornia crassipes has a threatening impact on the aquatic environment. For most small water areas with good ecology, daily manual monitoring and salvage require considerable financial material resources. Unmanned boats have important practical significance for automatic cleaning crassipes. To ensure that target can be accurately detected, we solve problems exist in l...

Pleurotus tuber-regium is a tuberous wild mushroom species, highly expensive, nutritious, very rich in proteins and known to possess medicinal values. The dwindling forests and the absence of commercial cultivation of this mushroom have resulted in scarcity of the sclerotia. The study was conducted to determine the optimum temperature, pH and light regime for the growth of P. tuber-regium and e...

The biodegradability of water hyacinth for biogas and biofertilizer production was studied under mesophilic conditions. effects pretreatments were also included in this investigation. It found that has a low 27% when monodigested, while 3:1 ratio with cow manure, the increases to 46%. At elevated biodegradability, biomethane potential 185 LCH4/kgVS, manure 216 LCH4/kgVS. Gompertz kinetic model ...
